BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a metal shell cutting and assembling machine, and more particularly to a machine capable of cutting away metal shells from a material tape and assembling the metal shell with a plastic body of a connector.
2. Description of the Prior Art
With the development of science and technology, it has been possible for enterprise to continue to improve the assembly efficiency and the quality of electrical products, and reduce the cost thereof. Correspondingly, it becomes more and more important for automatically assembling of the electrical products to employ high integrated and high intelligent device. Connectors are one of the electrical products.
For the connectors, the source material of metal shells of the connectors is generally a roll of metal sheet. As a convenience for plating, the metal shells of the connectors are configured to connect together with a material tape under the condition of having no specific demand. A pre-break section is located between the material tape and each metal shell. When assembling, the operator may take the metal shell by his hand, and then bend up and down the pre-break section to make the metal shell detach from the material tape. It is followed that the operator pre-inserts a plastic body of the connector into the metal shell and lastly puts them into a tool for being pressed completely, thereby completing to assemble the metal shell and the plastic body of a connector.
But both detaching the metal shell from the material tape and pre-inserting the plastic body into the metal shell are completed by the manual operation. On one hand, the manual operation can result in many problems such as increasing the labor intensity of the operator, reducing the manufacture efficiency and increasing the labor cost, and is disadvantageous for mass production. On the other hand, the manual operation may make the assembled product apt to be oxidized and deformed so the product quality is difficult to be ensured and the defective rate of the product is high.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The following embodiment with reference to the accompanying drawings now has been given for detail describing the technology, the feature, the object and the effect of the present invention.
Please refer to FIGS. 1 to 3, a metal shell cutting and assembling machine 1 of the present invention is used for cutting a material tape 2 with metal shells 21 and assembling the metal shell 21 with a plastic body 3 of a connector, as shown in FIG. 12. The metal shell cutting and assembling machine 1 comprises a frame 11, a material-feeding mechanism 12, a pre-press mechanism 13, a metal shell-cutting mechanism 14, a plastic body-inserting mechanism 15, a metal shell-inserting mechanism 16 and a controller (not shown in all FIGS). The frame 11 has a material tape-transferring channel provided for transferring the material tape. The metal shell-inserting mechanism 16 is mounted on the frame 11 above the material tape-transferring channel and is adjacent to an input port 1142 (labeled in FIG. 3) of the material tape-transferring channel. The pre-press mechanism 13 is mounted on the frame 11 above the material tape-transferring channel and is adjacent to an output port 1133 (labeled in FIG. 5) of the material tape-transferring channel. The material-feeding mechanism 12 is mounted on the frame 11 below the material tape-transferring channel and is adjacent to the input port 1142 of the material tape-transferring channel. The metal shell-cutting mechanism 14 is mounted on the frame 11 below the material tape-transferring channel and faces to the pre-press mechanism 13. When the pre-press mechanism 13 firmly presses the metal shell 21 of the material tape 2, the metal shell-cutting mechanism 14 can cut away the metal shell 21 from the material tape 2. The plastic body-inserting mechanism 15 is disposed on the frame 11 outside of the output port 1133 of the material tape-transferring channel, and can insert the plastic body 3 into the metal shell 21 pushed by the metal shell-inserting mechanism 16. The controller controls the coordinated movements of the material-feeding mechanism 12, the pre-press mechanism 13, the metal shell-cutting mechanism 14, the plastic body-inserting mechanism 15 and the metal shell-inserting mechanism 16. The specific movements are described as follows:
Please refer to FIGS. 1 to 4, the frame 11 has a bottom plate 111, a supporting plate 112 and a channel component defining the material tape-transferring channel. The bottom plate 111 is parallel to a horizontal plane. The supporting plate 112 is stood on the bottom plate 111. The channel component is mounted on the supporting plate 112. For convenience to adjust the position of the bottom plate 111, the bottom plate 111 is fixed to a sliding block 117, which is mounted on a guiding rail 118 provided for the sliding block 117 sliding thereon. In order to enhance the supporting force of the bottom plate 111 and the supporting plate 112, a plurality of reinforcing ribs 116 is disposed on a connection position of the bottom plate 111 and the supporting plate 112. The channel component includes an upper leading plate 113 and a lower leading plate 114. Two sides of the upper leading plate 113 are mounted on the supporting plate 112, and one end of the upper leading plate 113 is fixedly and straightly connected to the lower leading plate 114. The upper leading plate 113 and the lower leading plate 114 are under the state of parallel connection. The upper leading plate 113 disposes a push rod-sliding groove 1131 formed on a top surface 1130 thereof and provided for a push rod 161 (labeled in FIG. 5) sliding. An upper transferring channel 1132 is formed on a bottom surface of the upper leading plate 113. A lower transferring channel 1141 is formed on a top surface 1140 of the lower leading plate 114 and corresponding to the upper transferring channel 1132. The upper transferring channel 1132 and the lower transferring channel 1141 together form the material tape-transferring channel to transfer the material tape 2. In order to make the material tape 2 be more reliably transferred in the material tape-transferring channel, blocking plates 115 are formed on two sides of the bottom surface of the upper leading plate 113. A flattening device 19 is located adjacent to the input port 1142 of the material tape-transferring channel. It is noteworthy that the input port 1142 of the material tape-transferring channel is one end of the lower transferring channel 1141, which is apart from the upper leading plate 113; and the output port 1133 of the material tape-transferring channel is one end of the upper transferring channel 1132, which is apart from the lower leading plate 114.
Referring to FIGS. 1, 2, 8 and 9, the material-feeding mechanism 12 is mounted on the frame 11 below the material tape-transferring channel, as shown in FIG. 3. The material-feeding mechanism 12 is adjacent to the input port 1142 (labeled in FIG. 3) of the material tape-transferring channel. The material-feeding mechanism 12 includes a material tape-driving member, a pulling claw 121, a shaking block 123 and a pivot shaft (not shown in all FIGS). In this embodiment, the material tape-driving member is a material tape-transferring cylinder 122, which is mounted on the supporting plate 112 below the material tape-transferring channel and is electrically connected to the controller. The pulling claw 121 has a tip end 1211 for being inserted into a positioning hole of the material tape 2. For convenience to feed and release the material tape 2 by the pulling claw 121, a left side of the tip end 1211 is configured to a vertical flat surface, and a right side thereof is an inclined surface. To be convenient for the shaking block 123 driving the pulling claw 121 to draw the material tape 2, the pulling claw 121 and the shaking block 123 are straightly jointed together, and are reversely fixed two sides of the pivot shaft. The pivot shaft is rotatably mounted on the material tape-transferring cylinder 122. When the tip end 1211 of the pulling claw 121 is inserted into the positioning hole of the material tape 2, the pulling claw 121 and the shaking block 123 are parallel to one horizontal plane, and the shaking block 123 can be prevented by the frame 11 from rotating along clockwise. The clockwise is based on the shaking block 123 shown in FIG. 8. When the material tape-transferring cylinder 122 moves back and forth along the direction of the material tape-transferring channel, it can drive the pulling claw 121 to also move back and forth along the direction of the material tape-transferring channel. Because the tip end 1211 of the pulling claw 121 is inserted into the positioning hole of the material tape 2, the left side of the tip end 1211 is a vertical flat surface and the right side thereof is an inclined surface, the pulling claw 121 can transfer the material tape 2 only along a single direction thereby satisfying the cutting demand of the material tape 2.
Referring to FIGS. 1, 2, 6 and 7, the pre-press mechanism 13 is mounted on the frame 11 above the material tape-transferring channel, as shown in FIG. 3. And the pre-press mechanism 13 is adjacent to the output port 1133 (labeled in FIG. 5) of the material tape-transferring channel. The pre-press mechanism 13 includes a metal shell pressure plate 131, a pressure plate-driving member and a spring member (not shown in all FIGS). In this embodiment, the pressure plate-driving member is a pressure plate-driving cylinder 132, which is mounted on a cylinder fixture plate 133 and is electrically connected to the controller. The cylinder fixture plate 133 is mounted on a pressure plate-mounting plate 134, which is mounted on the upper leading plate 113. The spring member is elastically mounted between the cylinder fixture plate 133 and the metal shell pressure plate 131 so that the cylinder fixture plate 133 and the metal shell pressure plate 131 are elastically contacted with each other. An output shaft of the pressure plate-driving cylinder 132 is connected to one end of a cylinder-connecting block 135. The other end of the cylinder-connecting block 135 is connected to the metal shell pressure plate 131 for driving the metal shell pressure plate 131 to move toward the metal shell 21 for pressing the metal shell 21. In order to make the metal shell pressure plate 131 more stably and more reliably press the metal shell 21 of the material tape 2, the pressure plate-mounting plate 134 disposes a pressure plate-sliding groove (not shown in all FIGS), which can guide the metal shell pressure plate 131 to slide therein. The metal shell pressure plate 131 disposes a pressure plate-guiding rail to engage with the pressure plate-sliding groove.
Referring to FIGS. 1, 2, 8 and 9, the metal shell-cutting mechanism 14 is mounted on the frame 11 below the material tape-transferring channel, as shown in FIG. 3. The metal shell-cutting mechanism 14 faces to the pre-press mechanism 13 so that the mechanisms 14, 13 are separately located right below and right above the material tape-transferring channel, thereby ensuring that the metal shell-cutting mechanism 14 and the pre-press mechanism 13 can cooperate in harmony. The metal shell-cutting mechanism 14 includes a metal shell-cutting driving member, a metal shell cutter 141, a metal shell die base 143 cooperating with the metal shell cutter 141 in cutting the metal shell 21, and a cutter fixture seat 144. In this embodiment, the metal shell-cutting driving member is a metal shell-cutting cylinder 142 electrically connected to the controller. The metal shell die base 143 is straightly connected to the output port 1133 of the material tape-transferring channel and is mounted on the supporting plate 112. The metal shell die base 143 disposes a waste material passage (not shown in all FIGS), in which a waste material 20 remained after cutting away the metal shell 21 by the metal shell-cutting mechanism 14 can be continuously transferred. The metal shell-cutting cylinder 142 is mounted on the supporting plate 112 and can drive the metal shell cutter 141 to move toward the metal shell die base 143 for cutting the material tape 2 coming from the material-feeding mechanism 12 and for detaching the metal shell 21 and the waste material 20 from the material tape 2. The metal shell 21 after detached is held between the metal shell pressure plate 131 and the metal shell cutter 141. The cutter fixture seat 144 is mounted on the supporting plate 112 and disposes a cutter-sliding groove (not shown in all FIGS) provided for the metal shell cutter 141 sliding therein. The metal shell cutter 141 is mounted on the cutter fixture seat 144 and can freely slide thereby making the metal shell cutter 141 be capable of reliably working.
Referring to FIGS. 1, 2, 11 and 12, the plastic body-inserting mechanism 15 is disposed on the frame 11 outside of the output port 1133 of the material tape-transferring channel, as shown in FIG. 3. The plastic body-inserting mechanism 15 can push the plastic body 3 to make it be inserted into the metal shell 21, which is coming from and pushed by the metal shell-inserting mechanism 16. The plastic body-inserting mechanism 15 includes a frame body 154, a plastic body-pushing driving member and a plastic body-pushing rod 151. The frame body 154 forms a plastic body-transferring passage 150 and a push rod passage 153 perpendicularly communicating with the plastic body-transferring passage 150. The push rod passage 153 is parallel disposed above the material tape-transferring channel. Horizontal central lines of the push rod passage 153 and the material tape-transferring channel coincide with each other. In one embodiment, the plastic body-pushing driving member is a plastic body-pushing cylinder 152 electrically connected to the controller. An output shaft of the plastic body-pushing cylinder 152 is connected to one end of a plastic body-pushing head 156, and the other end of the plastic body-pushing head 156 is fixedly connected to the plastic body-pushing rod 151 for driving the plastic body-pushing rod 151 to move along the push rod passage 153 thereby pushing the plastic body 3 to make it be assembled with the metal shell 21.
Referring to FIGS. 1, 2 and 5, the metal shell-inserting mechanism 16 is mounted on the frame 11 above the material tape-transferring channel, as shown in FIG. 3. The metal shell-inserting mechanism 16 is adjacent to the input port 1142 (labeled in FIG. 3) of the material tape-transferring channel. The metal shell-inserting mechanism 16 includes a metal shell-pushing rod 161 and a metal shell-pushing driving member. In one embodiment, the metal shell-pushing driving member is a metal shell-pushing cylinder 162, which is mounted on the upper leading plate 113 by a cylinder fixture seat 164 and is electrically connected to the controller. An output shaft of the metal shell-pushing cylinder 162 is connected to one end of a metal shell-pushing head 165, and the other end of the metal shell-pushing head 165 is fixedly connected to the metal shell-pushing rod 161. The metal shell-pushing cylinder 162 can drive the metal shell-pushing head 165 to work, and then the metal shell-pushing head 165 can drive the metal shell-pushing rod 161 to slide along the push rod-sliding groove 1131 of the upper leading plate 113. Whereby the metal shell 21, which is held between the metal shell pressure plate 131 of the pre-press mechanism 13 and the metal shell cutter 141 of the metal shell-cutting mechanism 14, can be pushed unto an assembling end of the push rod passage 153 of the plastic body-inserting mechanism 15.
In order to ensure the assembly quality of the metal shell 21, the metal shell-inserting mechanism 16 further includes a pre-inserting driving member, which is a pre-inserting driving cylinder 163 mounted on the cylinder fixture seat 164 and electrically connected to the controller. The metal shell-pushing cylinder 162 is mounted on the pre-inserting driving cylinder 163. When assembling the metal shell 21, the pre-inserting driving cylinder 163 first starts to work for driving the metal shell-pushing cylinder 162 to move along the material tape-transferring channel, and for simultaneously driving the metal shell-pushing rod 161 to work. When the pre-inserting driving cylinder 163 moves to a designated position, the metal shell-pushing cylinder 162 starts to work. Whereby the metal shell 21 attached on metal shell-pushing rod 161 can be pushed unto the assembling end of the push rod passage 153 of the plastic body-inserting mechanism 15 for assembling.
Referring to FIGS. 1, 2 and 10, the metal shell cutting and assembling machine 1 also comprises a waste material-cutting mechanism 18 mounted on the frame 11 below the material tape-transferring channel, as shown in FIG. 3. The waste material-cutting mechanism 18 includes a waste material cutting driving member, a waste material cutter 181, a waste material die base 183 and a waste material transferring component. In one embodiment, the waste material cutting driving member is a waste material-cutting cylinder 182, which is mounted on the bottom plate 111 by a cylinder bracket 184 and is connected to the controller. The waste material die base 183 is mounted on a tail end of the waste material passage of the metal shell die base 143, and is straightly connected to the waste material passage. The waste material cutter 181 is mounted on the supporting plate 112 by a cutter fixture base 185. The cutter fixture base 185 disposes a cutter-sliding groove 1850 provided for the waste material cutter 181 sliding therein so that the waste material cutter 181 can be capable of reliably working. The waste material transferring component includes a first connecting rod 186 and a second connecting rod 187. One end of the first connecting rod 186 is pivotally connected to a piston rod of the waste material-cutting cylinder 182, and the other end thereof is pivotally connected to one end of the second connecting rod 187. The other end of the second connecting rod 187 is pivotally connected to the frame 11 by a pivotal connecting frame 188 and touches onto the waste material cutter 181. In order to enhance the touching reliability between the second connecting rod 187 and the waste material cutter 181 and reduce the friction force therebetween, an idler wheel 189 is disposed on one end of the waste material cutter 181. The waste material-cutting cylinder 182 can drive the first connecting rod 186, which is pivotally connected to the piston rod thereof, to work. Then the first connecting rod 186 can drive the end of the second connecting rod 187, which is pivotally connected to it, to work. Whereby the other end of the second connecting rod 187 can be driven to swing up and down around the pivotal connecting frame 188. The second connecting rod 187 swinging up and down can push the waste material cutter 181 to slide up and down in the cutter-sliding groove 1850 of the cutter fixture base 185. The waste material cutter 181 can cooperate with the waste material die base 183 in cutting away the waste material 20 from the material tape 2. For convenience to reclaim the waste material 20, the present machine 1 also comprises a waste material collection device, which is disposed adjacent to a tail end of the waste material passage of the metal shell die base 143. The waste material collection device is a waste material collection box 17.
Referring to FIGS. 1 to 12, the work principle of the present metal shell cutting and assembling machine 1 will be specifically described.
The following is an assembling process of the metal shell 21 and the plastic body 3 of the connector.
First, the material tape 2 with the metal shell 21 passes through the flattening device 19 to be mounted in the material tape-transferring channel of the frame 11. The tip end 1211 of the pulling claw 121 is inserted into the positioning hole of the material tape 2. Next, the controller controls the material tape-transferring cylinder 122 to move along a first direction pointed by an arrow A of FIG. 1. When the material tape-transferring cylinder 122 moves from a rightmost end to a leftmost end, the material tape 2 can be transferred a distance, which is equal to a distance between two adjacent positioning holes of the material tape 2, and is also equal to a distance between two cutting sections of two adjacent metal shell 21 of the material tape 2. The moving distance of the material tape-transferring cylinder 122 can be freely adjusted according to two adjacent positioning holes of the different material tape 2. When the material tape-transferring cylinder 122 arrives at the leftmost end, the controller controls the pressure plate-driving cylinder 132 of the pre-press mechanism 13 to move along a second direction pointed by an arrow B of FIG. 1. Because there is the spring member disposed between the metal shell pressure plate 131 and the cylinder fixture plate 133, the metal shell pressure plate 131 can follow the cylinder-connecting block 135 fixed on the output shaft of the pressure plate-driving cylinder 132 to move downward together under the function of the gravity of the metal shell pressure plate 131 until firmly pressing the metal shell 21 of the material tape 2 transferred by the material-feeding mechanism 12. Whereby it has got ready for the metal shell-cutting mechanism 14 to cutting the metal shell 21.
Secondly, the controller controls a piston rod of the metal shell-cutting cylinder 142 of the metal shell-cutting mechanism 14 to move along a reverse direction of the second direction pointed by the arrow B of FIG. 1. The piston rod of the metal shell-cutting cylinder 142 can push the metal shell cutter 141 to slide in the cutter fixture seat 144. The metal shell cutter 141 cooperating with the metal shell die base 143 can cut away the metal shell 21 from the material tape 2. When the metal shell cutter 141 after cutting away the metal shell 21 continues to be pushed upward, the cylinder-connecting block 135 carrying the metal shell pressure plate 131 can only move along the reverse direction of the second direction pointed by the arrow B of FIG. 1. Specially, the metal shell cutter 141 can push the metal shell pressure plate 131 to move along the reverse direction of the second direction pointed by the arrow B of FIG. 1, because the pushing force of the metal shell cutter 141 produced by the metal shell-cutting cylinder 142 is larger than a resultant force including the gravity of the metal shell pressure plate 131 and the elastic force of the spring member. Now, the metal shell 21 after being cut away can be held between the metal shell cutter 141 and the metal shell pressure plate 131, and just faces to the metal shell-pushing rod 161 of the metal shell-inserting mechanism 16. Namely, the metal shell 21 is lying on a moving passage of the metal shell-pushing rod 161 of the metal shell-inserting mechanism 16. Whereby the metal shell-pushing rod 161 can push the metal shell 21 onto the assembling end of the push rod passage 153 of the plastic body-inserting mechanism 15.
Simultaneously, the material tape 2 after being cutting away the metal shell 21 passes through the waste material passage of the metal shell die base 143 and is transferred at the waste material-cutting mechanism 18 provided for cutting away the waste material 20. Now, the controller controls the piston rod of the waste material-cutting cylinder 182 of the waste material-cutting mechanism 18 to extend toward the bottom plate 111, so that the first connecting rod 186 pivotally connected to the piston rod of the waste material-cutting cylinder 182 can be driven to move, and can further drive the one end of the second connecting rod 187, which is pivotally connected to the first connecting rod 186, to move. Therefore, the other end of the second connecting rod 187 can be raised toward the reverse direction of the second direction pointed by the arrow B of FIG. 1 around the pivotal connecting frame 188, for pushing the waste material cutter 181 to slide in the cutter fixture base 185. The waste material cutter 181 cooperating with the cutter fixture base 185 can cut away the waste material 20. The waste material 20 after being cut away just falls into the waste material collection box 17.
Next, the controller controls the pre-inserting driving cylinder 163 of the metal shell-inserting mechanism 16 to move along the first direction pointed by the arrow A of FIG. 1. The pre-inserting driving cylinder 163 can drive the metal shell-pushing cylinder 162 fixedly connected thereto to move, so that the metal shell-pushing rod 161 can follow the metal shell-pushing cylinder 162 to move in the push rod-sliding groove 1131 of the upper leading plate 113 for engaging with the metal shell 21, which is held between the metal shell pressure plate 131 and the metal shell cutter 141. When the pre-inserting driving cylinder 163 moves to the designated position, the controller controls the metal shell-pushing cylinder 162 to continue to move along the first direction pointed by the arrow A of FIG. 1, and to drive the metal shell-pushing head 165 to move. Whereby the metal shell-pushing rod 161 fixed on the metal shell-pushing head 165 can be driven to continue to slide in the push rod-sliding groove 1131 and can push the metal shell 21 onto the assembling end of the push rod passage 153 of the plastic body-inserting mechanism 15. Then, the controller controls the plastic body-pushing cylinder 152 of the plastic body-inserting mechanism 15 to move for pushing the plastic body-pushing head 156 connected to the output shaft thereof to move along a third direction pointed by an arrow C of FIG. 1. Whereby the plastic body-pushing rod 151 fixed on the plastic body-pushing head 156 can be driven to slide along the push rod passage 153 of the frame body 154, to push the plastic body 3, which is transferred from the plastic body-transferring passage 150 to the push rod passage 153, onto the assembling end of the push rod passage 153, and to assemble the plastic body 3 and the metal shell 21 coming from the metal shell-pushing rod 161 into a combination component.
When restoring, the controller controls the pressure plate-driving cylinder 132 of the pre-press mechanism 13 to move along the reverse direction of the second direction pointed by the arrow B of FIG. 1, and to pull the cylinder-connecting block 135 connected to the output shaft thereof to upward. The cylinder-connecting block 135 pulled upward can drive the metal shell pressure plate 131 to slide in the pressure plate-mounting plate 134. Because the spring member is disposed between the metal shell pressure plate 131 and the cylinder fixture plate 133, the metal shell pressure plate 131 can follow the cylinder-connecting block 135 to slowly restore to the original state for being ready to next work. Next, the controller controls the plastic body-pushing cylinder 152 of the plastic body-inserting mechanism 15 to restore along a reverse direction of the third direction pointed by the arrow C of FIG. 1 for being ready to next work. Now, the controller controls the piston rod of the waste material-cutting cylinder 182 of the waste material-cutting mechanism 18 to retract away from the bottom plate 111. The first connecting rod 186 pivotally connected to the piston rod of the waste material-cutting cylinder 182 can be driven to move, and further drive the one end of the second connecting rod 187 to move. Now, the other end of the second connecting rod 187 can move downward around the pivotal connecting frame 188, namely move toward the bottom plate 111, so that the waste material cutter 184 can follow the second connecting rod 187 to move downward, thereby making the waste material-cutting mechanism 18 restore to the original state for being ready to next work.
Then, the controller controls the piston rod of the metal shell-cutting cylinder 142 of the metal shell-cutting mechanism 14 to restore along the second direction pointed by the arrow B of FIG. 1. Under the function of the elastic force and the gravity of the metal shell cutter 141, the metal shell cutter 141 can follow the piston rod of the metal shell-cutting cylinder 142 to restore for being ready to next work. Now, the controller controls the pre-inserting driving cylinder 163 together with the metal shell-pushing cylinder 162 to move along the reverse direction of the first direction pointed by the arrow A of FIG. 1, so that the metal shell-pushing rod 161 connected to the metal shell-pushing head 165 can be driven to slide in the push rod-sliding groove 1131 of the upper leading plate 113 and to move away from the assembling end of the push rod passage 153 for finally restoring to the original state. The combination component disengaged with the metal shell-pushing rod 161 can be transferred to a corresponding device along a component-collecting channel 155 of the frame body 154.
Finally, the controller controls the metal shell-pushing cylinder 162 continues to move along the reverse direction of the first direction pointed by the arrow A of FIG. 1, and to drive the metal shell-pushing head 165 to restore, and to further drive the metal shell-pushing rod 161 to restore for being ready to next work. Now, the controller controls the material tape-transferring cylinder 122 of the material-feeding mechanism 12 to move along the reverse direction of the first direction pointed by the arrow A of FIG. 1 thereby driving the pulling claw 121 and the shaking block 123 to follow it to move. Because the left side of the tip end 1211 of the pulling claw 121 is a vertical flat surface and the right side thereof is an inclined surface, the pulling claw 121 can not drive the material tape 2 to move along the reverse direction of the first direction pointed by the arrow A of FIG. 1, thereby ensuring the working reliability of the material-feeding mechanism 12. After the material tape-transferring cylinder 122 restoring to the original state, because the pulling claw 121 and the shaking block 123 straightly jointed together are located two sides of the pivot shaft, the pulling claw 121 can rotate along clockwise (as based on FIG. 9) around the pivot shaft under the gravity of the shaking block 123 until the frame 11 prevents the shaking block 123 from rotating. Now, the pulling claw 121 and the shaking block 123 are again parallel to the horizontal plane, and the tip end 1211 of the pulling claw 121 is again inserted into a next positioning hole of the material tape 2 for being ready to next work.
As described above, the metal shell cutting and assembling machine 1 employs the material-feeding mechanism 12 to automatically transfer the material tape 2, and employs the pre-press mechanism 13 to firmly press the metal shell 21 on the material tape 2 transferred by the material-feeding mechanism 12, and employs the metal shell-cutting mechanism 14 can cut away the metal shell 21 pressed by the pre-press mechanism 13. So the present machine 1 can automatically cut the material tape 2 with the metal shell 21. Moreover, the present machine 1 also employs the metal shell-inserting mechanism 16 to push the metal shell 21, which is held between the pre-press mechanism 13 and the metal shell-cutting mechanism 14, onto the plastic body-inserting mechanism 15, so that the plastic body 3 coming from the plastic body-inserting mechanism 15 and the metal shell 21 coming from the metal shell-inserting mechanism 16 can be assembled together. Therefore, the present machine 1 can be capable of automatically assemble the metal shell 21 with the plastic body 3. The present machine 1 can enhance the manufacture efficiency, reduce the labor cost and be suitable for mass production. Moreover the obtained assembling component has a good uniformity and a high qualification rate.
