Description

Technical Field

[0001] The utility model relates to the technical field of photoelectric switches, in particular to a testing device for photoelectric switches. Background Art

[0002] A photoelectric switch, short for photoelectric proximity switch, detects the presence of an object by blocking or reflecting a light beam. This is accomplished by connecting a synchronous circuit to the circuit. This detection is not limited to metal; any object that reflects (or blocks) light can be detected. The photoelectric switch converts input current into a light signal at the transmitter, which is then emitted. The receiver then detects the target object based on the intensity or presence of the received light.

[0003] After the photoelectric switch is produced, in order to ensure that it can work normally, the photoelectric switch needs to be powered on and tested. Before testing the photoelectric switch, the inspection personnel need to place the photoelectric switches one by one in the fixture and fix them before testing. The light beam emitted by the photoelectric switch is blocked by the baffle fixed on the fixture to detect whether the photoelectric switch is working properly.

[0004] However, in the prior art, multiple photoelectric switches are generally used for testing to facilitate detection. Since photoelectric switches are divergent, there will generally be a certain offset. If one of the adjacent photoelectric switches does not emit light, the light beam emitted by the photoelectric switch that normally emits a light beam may diffuse into the photoelectric switch that cannot emit a light beam normally, causing the photoelectric switch that cannot normally operate to pass the test, thereby reducing the accuracy of the photoelectric switch test.

A fixing hole 11 is defined in the center of the back of each of the regions. The fixing hole 11 is located on the fixing mechanism 2.

[0029] A driving cavity 12 is provided on the other side of the interior of the base 1. A rotating shaft 6 is provided downward at the front end above the top of the base 1. The bottom of the rotating shaft 6 is located below the driving cavity 12. A turbine 8 is provided on the surface of the rotating shaft 6 and located at the driving cavity 12. The surface of the turbine 8 is meshed with a worm rod 9, and the two ends of the worm rod 9 are located on both sides of the driving cavity 12. A baffle 5 is provided on the top of the surface of the rotating shaft 6, and the bottom of the baffle 5 is located at the top of the base 1.

[0030] Furthermore, a drive motor 7 is fixedly connected to one side of the base 1 , and an output end of the drive motor 7 is connected to the worm gear 9 .

[0031] Furthermore, sliding grooves 15 are downwardly provided on both sides of the top of the fixing mechanism 2 , and the bottom of the sliding grooves 15 is in the same horizontal plane as the top of the base 1 .

[0032] Furthermore, an electric telescopic rod 14 is fixedly connected to the bottom center of the sliding groove 15, the tops of the two electric telescopic rods 14 are connected to the sliding rod 13, the sliding rod 13 is engaged and slidably connected to the sliding groove 15, and the front of the sliding groove 15 is connected to the two ends of the back of the fixed plate 3.

[0033] Furthermore, a through slot is provided at the center of the fixing plate 3 , the size of the through slot is connected to the size of the fixing inner cavity 17 , and the light-transmitting plate 4 is fixedly connected to the interior of the through slot.

[0034] Furthermore, a reflector is fixedly connected to the inner side surface of the baffle 5 .

[0035] Specifically, the utility model drives the motor 7 to rotate the worm gear 9, which drives the turbine 8 to rotate. The rotation of the turbine 8 rotates the shaft 6, which drives the baffle 5 to rotate. The baffle 5 drives the reflector to rotate, thereby adjusting the angle of the reflector, allowing the device to test the photoelectric switch at different angles, thereby performing multi-angle testing, avoiding photoelectric switches that cannot work normally from passing the test, and improving the accuracy of the photoelectric switch test.

[0036] The present invention is a test device for a photoelectric switch. In a fixing mechanism 2, a fixing inner cavity 17 is divided into several areas by a horizontal partition plate 10 and a vertical partition plate 16. The size of the area matches the size of the photoelectric switch. The photoelectric switch can be fixed by inserting the connecting wire of the photoelectric switch into the fixing hole 11. The photoelectric switch can be fixed very simply by inserting the connecting wire into the fixing hole 11 and connecting it to a power supply. The fixing of the photoelectric switch in the present invention is relatively simple, which is conducive to improving detection efficiency.

[0037] In addition, after the fixation is completed, the electric telescopic rod 14 is extended to the minimum value, and the fixing plate 3 is covered on the surface of the fixing mechanism 2 to prevent the photoelectric switch from falling, thereby further fixing the photoelectric switch. In order to prevent the fixing plate 3 from affecting the photoelectric switch, a light-transmitting plate is provided at the center of the fixing plate 3.

[0038] Working principle: When in use, the staff first inserts the rear end connection line of the photoelectric switch to be tested into one of the fixing holes 11, then places the photoelectric switch body into a certain area separated by the fixed inner cavity 17, inserts the connection line into the interface of the power supply to fix the photoelectric switch, and then fixes the other photoelectric switches according to the above method.

[0039] After all the fixation is completed, the staff will simultaneously start the two electric telescopic rods 14 through the controller to extend and retract the electric telescopic rods 14, thereby causing the sliding rod 13 to slide downward along the sliding groove 15. When the electric telescopic rods 14 are extended to the shortest value, the fixing plate 3 will be covered on the surface of the fixing mechanism 2 to fix the photoelectric switch again to improve the stability of the fixation.

[0040] Then the photoelectric switch can be tested. During the test, the light-emitting board can be moved by driving the motor 7. The movement of the baffle 5 uses the self-locking property of the turbine 8 and the worm rod 9 to prevent the baffle 5 from automatically rotating when it does not need to rotate, thereby affecting the measurement.

[0041] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
