This application claims priority of Taiwanese Patent Application No. 106117527, filed on May 26, 2017, and Taiwanese Patent Application No. 106207571, filed on May 26, 2017.
The disclosure relates to a sensor, and more particularly to a sensor with a light signal module having multi-directional light emitting surfaces.
In the manufacturing process of semiconductors, sensing and monitoring of the flow rate and the pressure of a fluid are required to ensure normal operation of a machine (such as robotic arm, vacuum chuck, etc.), and conventional flow meters and manometers are utilized as monitoring devices. These monitoring devices generally include a warning light at a front side thereof to be seen by a user for alarming the user when the operation of the machine is not normal (for example, when the flow rate or the pressure of the fluid flowing in the machine is not within a certain range). However, it is not easy to see the warning light when the user moves around and is not in front of the machine, and the user may not be able to respond to an abnormal operation promptly.
Therefore, an object of the disclosure is to provide a sensor that can alleviate at least one of the drawbacks of the prior art.
According to the disclosure, a sensor is provided to measure an object, and includes a housing, a sensor module and a light signal module. The sensor module is disposed in the housing, and is configured to detect the object and to send a measured information so as to produce an instruction set corresponding to the measured information. The light signal module is disposed in the housing, and is electrically connected with the sensor module. The light signal module is actuated by the instruction set to emit light therefrom. The light signal module has a front light emitting surface and a lateral light emitting surface which respectively face two different directions from each other. Therefore, a user can easily observe the light emitting from the front and lateral light emitting surfaces of the light signal module.
Other features and advantages of the disclosure will become apparent in the following detailed description of the embodiments with reference to the accompanying drawings, of which:
Before the disclosure is described in greater detail, it should be noted that where considered appropriate, reference numerals or terminal portions of reference numerals have been repeated among the figures to indicate corresponding or analogous elements, which may optionally have similar characteristics.
Referring to FIGS. and 2, a first embodiment of the sensor 10 according to the disclosure is adapted to be mounted on an upright plate wall 8 which has a mounting hole, and is disposed for measuring an operating parameter an object (not shown). The operating parameter is, for example, flow rate or pressure of a fluid flowing in the object. The sensor 10 includes a housing 1, a sensor module 2 (see

With reference to
The housing 1 is made from a non-translucent material. The light emitting unit 32 is mounted on a circuit board 33 disposed adjacent to the translucent lampshade 31.
In this embodiment, the translucent lampshade 31 is attached to the front edge 120 of the surrounding wall 12 and the front wall 11 of the housing 1. The front light emitting surface 311 is flush with the front wall 11. The direction that the front light emitting surface 311 faces is substantially perpendicular to the direction that the lateral light emitting surface 312 faces. The translucent lampshade 31 is in the form of a square frame. Specifically, the lateral light emitting surface 312 includes a left light emitting surface portion, a right light emitting surface portion opposite to the left light emitting surface portion, an upper light emitting surface portion, and a lower light emitting surface portion opposite to the upper light emitting surface portion. Also, the translucent lampshade 31 has first and second translucent sections 313, 314 adjoined to each other. In this embodiment, the first and second translucent sections 313, 314 are disposed at upper and lower sides, respectively, to be opposite and adjoined to each other in an upper-and-lower direction and cooperatively define the front and lateral light emitting surfaces 311, 312. The light emitting unit 32 has first and second light emitting assemblies 321, 322 which are disposed at the first and second translucent sections 313, 314, respectively. The light signal module 3 further has a light resist unit (not shown) disposed between the first and second translucent sections 313, 314 to prevent passage of light emitting from the first light emitting assembly 321 through the second translucent section 314, and passage of light emitting from the second light emitting assembly 322 through the first translucent section 313. The instruction set has a plurality of commands. The first light emitting assembly 321 is actuated by one of the commands to emit light through the first translucent section 313. The second light emitting assembly 322 is actuated by another one of the commands to emit light through the second translucent section 314. The light emitted from each of the first and second light emitting assemblies 321, 322 may be red or green in color. That is, each of the first and second light emitting assemblies 321, 322 may emit light having at least one color. The numbers of the translucent sections of the translucent lampshade 31 and the light emitting assemblies of the light emitting unit 32 may be changed depending on different needs, e.g., only one or more than two.
A first signal and a second signal are generated by the control unit in response to the measured information, and are transmitted to a control computer (not shown) through a transmission hole 121 (see
The sensor 10 may include a display module 4 and an input module 5 disposed at the front of the housing 1 and electrically connected with the control unit.
With reference to
Referring to
In this embodiment, the light signal module 3 is in the form of a rectangular frame, and the first and second translucent sections 313, 314 are disposed opposite to and adjoined to each other in a left-and-right direction (The first translucent section 313 is at a left side while the second translucent section 314 is at a right side).
Moreover, the light emitting unit 32 is disposed to generate a first light with a first color and a second light with a second color that is different from the first color. The measured information has a measured value. The sensor module 2 has a first predetermined value built therein such that the light emitting unit 32 is actuated by the instruction set to emit the first light with the first color on condition that the measured value is smaller than the first predetermined value, and such that the light emitting unit 32 is actuated by the instruction set to emit the second light with the second color on condition that the measured value is equal to or larger than the first predetermined value. Also, the light emitting unit 32 is disposed to further generate a third light with a third color that is different from both the first and second colors. The sensor module 2 has a second predetermined value built therein and larger than the first predetermined value such that the light emitting unit 32 is actuated by the instruction set to emit the second light with the second color on condition that the measured value is equal to or larger than the first predetermined value and smaller than the second predetermined value, and such that the light emitting unit 32 is actuated by the instruction set to emit the third light with the third color on condition that the measured value is equal to or larger than the second predetermined value.
For example, in the second embodiment, the first color is green, the second color is orange, and the third color is red. The measured information has a value representing a pressure of the object and shown on a left side of the display module 4, and another value representing a flow rate of the object and shown on a right side of the display module 4. The sensor module 2 further has a third predetermined value built therein and a fourth predetermined value built therein and larger than the third predetermined value. The predetermined values are built in the control unit by a user input from the input module 5. When the pressure value is smaller than the first predetermined value, the first light emitting assembly 321 is actuated by one command of the instruction set to emit the green light (the first light). When the pressure value is equal to or larger than the first predetermined value but smaller than the second predetermined value, the first light emitting assembly 321 is actuated by one command of the instruction set to emit the orange light (the second light). When the pressure value is equal to or larger than the second predetermined value, the first light emitting assembly 321 is actuated by one command of the instruction set to emit the red light (the third light). On the other hand, when the flow rate value is smaller than the third predetermined value, the second light emitting assembly 322 is actuated by one command of the instruction set to emit the green light (the first light). When the flow rate value is equal to or larger than the third predetermined value but smaller than the fourth predetermined value, the second light emitting assembly 322 is actuated by one command of the instruction set to emit the orange light (the second light). When the flow rate value is equal to or larger than the fourth predetermined value, the second light emitting assembly 322 is actuated by one command of the instruction set to emit the red light (the third light). Thus, a user can monitor the pressure and flow rate of the object by seeing front, upper and lower sides of the light signal module 3 of the sensor 10.
The various aspects of the light signal module 3 can deviate from the example shown and described herein. For example, the light signal module may be configured to blink or to be lighted to alarm a user. Each of the first and second light emitting assemblies 321, 322 is configured by an LED capable of emitting light of various colors. In the modified forms, each of the first and second light emitting assemblies 321, 322 may have a plurality of LEDs capable of emitting light with various colors.
Furthermore, in the above embodiments, the light signal module 3 is configured to surround the housing 1. Alternatively, the light signal module 3 may be formed as an elongated strip, or any form having the front and lateral light emitting surfaces 311, 312.
With reference to
As illustrated, according to the sensor 10 of the disclosure having front and lateral light emitting surfaces 311, 312 which respectively face two different directions from each other, a user can easily see the light signal module 3 for facilitating monitoring of a machine or an object. With the sensor module 2 capable of producing the instruction set corresponding to the measured information to actuate the light signal module 3 to emit light, the user can readily get the measured information from the light signal module 3. Furthermore, with the coupling frame 61 and the front protective cover 7 made from a translucent material, the light emitted from the light signal module 3 can pass therethrough.
While the disclosure has been described in connection with what are considered the exemplary embodiments, it is understood that this disclosure is not limited to the disclosed embodiments but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
