Patent Application

The subject matter herein generally relates to disassembly devices, and more particularly to a disassembly device for disassembling a test object.
Generally, after an object is made, functions of the object need to be tested. Some objects need to be disassembled during the testing process. However, the disassembly method in the related art generally uses tools such as wrenches and screwdrivers, which may damage the object.
Implementations of the present disclosure will now be described, by way of embodiments, with reference to the attached figures.
It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. Additionally, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures and components have not been described in detail so as not to obscure the related relevant feature being described. The drawings are not necessarily to scale and the proportions of certain parts may be exaggerated to better illustrate details and features. The description is not to be considered as limiting the scope of the embodiments described herein.
Several definitions that apply throughout this disclosure will now be presented.
The term “coupled” is defined as connected, whether directly or indirectly through intervening components, and is not necessarily limited to physical connections. The connection can be such that the objects are permanently connected or releasably connected. The term “substantially” is defined to be essentially conforming to the particular dimension, shape, or other word that “substantially” modifies, such that the component need not be exact. For example, “substantially cylindrical” means that the object resembles a cylinder, but can have one or more deviations from a true cylinder. The term “comprising” means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in a so-described combination, group, series and the like.
The first actuating portion 11 and the second actuating portion 12 fix different portions of the test object 20. The first actuating portion 11 applies a pulling force F1 on the test object 20, and the second actuating portion 12 applies a pulling force F2 on the test object 20 opposite the pulling force F1, thereby disassembling the test object 20. As shown in
The disassembly device 10 can be used for disassembling the test object 20 to be tested. In one embodiment, the test object 20 is a waterproof structure of a lens end of an outdoor walkie-talkie, which is formed by ultrasonic welding, and a welding strength can be tested by disassembling the test object 20 by the disassembly device 10. The higher the welding strength is, the better the waterproof performance. In one embodiment, the test object 20 is disassembled by the disassembly device 10, and values of the pulling force F1 and the pulling force F2 are between 30 and 50 kgf.
Referring to
The fixing plate 111 is substantially a flat plate and defines a first through hole 1111. The first through hole 1111 is used for holding a preset portion of the test object 20 to fix the test object 20. A plurality of connecting posts 113 is mounted on a surface of the fixing plate 111 facing the actuating plate 112, and the plurality of connecting posts 113 is located between the fixing plate 111 and the actuating plate 112. In one embodiment, the connecting posts 113 extend in a direction perpendicular to the surface of the fixing plate 111. The plurality of connecting posts 113 is used for fixing and connecting the fixing plate 111 and the actuating plate 112. Each connecting post 113 is fixedly connected to the actuating plate 112 by a fixing member 114, such as a screw. In one embodiment, each connecting post 113 is integrally formed with the fixing plate 111. In other embodiments, each connecting post 113 is fixed to the fixing plate 111 by a fixing member 123.
The actuating plate 112 is substantially a flat plate. The actuating plate 112 defines a plurality of connecting holes 1121 penetrating the actuating plate 112. A number of the connecting holes 1121 is greater than a number of the connecting posts 113. A same number of the connecting holes 1121 as the connecting posts 1113 are used for setting the fixing members 114, and the remaining number of connecting holes 1121 are used for fixedly connecting the actuating plate 112 to an external tensile tester (not shown). The pulling force F1 applied by the first actuating portion 11 on the test object 20 is measured by the tensile tester. In one embodiment, a number of the connecting holes 1121 for fixedly connecting the tensile tester is one and is located at a center of the actuating plate 112. In one embodiment, there are nine connecting holes 1121, eight connecting posts 113, and eight fixing members 114.
The second actuating portion 12 is substantially flat. A second through hole 121 is defined in the second actuating portion 12. The second through hole 121 is used for receiving the test object 20. The second actuating portion 12 defines a plurality of connecting holes 122. A portion of the connecting holes 122 is used for setting the fixing members 123 to fix the test object 20, and the remaining portion of the connecting holes 122 is used for fixing the second actuating portion 12 to at least one external tensile tester (not shown) for testing the pulling force F2. In one embodiment, two connecting holes 122 are defined in the second actuating portion 12 for fixedly connecting to two tensile testers, respectively. The two tensile testers are connected symmetrically to the second actuating portion 12.
Shapes of the first through hole 1111 and the second through hole 121 are designed to match outer shapes of portions of the test object 20 to be fixed.
For example, as shown in
A protrusion 221 is provided on a side of the bottom cover 22 facing away from the top cover 21. Referring to
In one embodiment, the first actuating portion 11 and the second actuating portion 12 are made of aluminum. In another embodiment, the first actuating portion 11 and the second actuating portion 12 are made of stainless steel for enhancing the tensile strength. In another embodiment, the fixing plate 111 and the second actuating portion 12 are made of elastic materials for accommodating test objects of different shapes and sizes.
In one embodiment, the fixing plate 111 further defines an opening 1112 penetrating one side edge of the fixing plate 111 and communicating with the first through hole 1111. The opening 1112 enhances deformation of the fixing plate 111 for accommodating test objects of different shapes and sizes.
Thicknesses of the fixing plate 111, the actuating plate 112, and the second actuating portion 12 may be equal or different. The thicknesses of the fixing plate 111, the actuating plate 112, and the second actuating portion 12 are defined as d, wherein 2 mm≤d≤4 mm. In one embodiment, the fixing plate 111, the actuating plate 112, and the second actuating portion 12 have the same thickness, d=2 mm. In another embodiment, the thicknesses of the fixing plate 111, the actuating plate 112, and the second actuating portion 12 have the same thickness, d=4 mm. By increasing the thicknesses, the tensile strength of the disassembly device 10 is enhanced.
The disassembly device 10 uses the first actuating portion 11 and the second actuating portion 12 to apply the pulling force F1 and the pulling force F2 in opposite directions to disassemble the test object 20. Compared to the destruction tool in the related art (such as a wrench), it is not easy to damage the test object 20, and the test object 20 can be reassembled and put into use. Therefore, the test fixture 10 is beneficial in prolonging the service life of the test object 20 and saving manufacturing costs.
The embodiments shown and described above are only examples. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the detail, including in matters of shape, size and arrangement of the parts within the principles of the present disclosure up to, and including, the full extent established by the broad general meaning of the terms used in the claims.
