[0002] In the process of producing proximity sensors, it is necessary to test the performance of the proximity sensors from the side. The existing test devices for the production of inductive proximity sensors can meet the basic needs of testing the various performances of proximity sensors, but usually the proximity sensors are flexibly fixed by a clamping structure. Before each test, the proximity sensor needs to be placed in the clamping structure and then clamped and fixed. After the test of the proximity sensor is completed, the clamping and fixation of the proximity sensor needs to be released before the proximity sensor can be taken out. Before and after the test, there is an additional operation of flexibly fixing the proximity sensor in sequence, which is very troublesome and will affect the basic needs of testing the proximity sensor.

[0003] For example, the utility model with announcement number CN 217213209 U discloses a testing device for proximity sensor production. In the technical solution of this patent, in the process of detecting the proximity sensor, it is necessary to first place the proximity sensor between a first limit block and a second limit block, and then clamp and fix the proximity sensor by means of a first electric push rod, a first transmission rod, a second electric push rod, and a second transmission rod. After the proximity sensor is fixed, it is necessary to release the clamping and fixation of the proximity sensor by means of the first electric push rod, the first transmission rod, the second electric push rod, and the second transmission rod, and then the proximity sensor can be taken out. The placement and removal of the proximity sensor cannot be completed quickly, which is very troublesome, and thus affects the efficiency of testing the proximity sensor. Utility Model Content

In the following description, a large number of specific details are given in order to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details.

[0024] like Figure 1 , 2 As shown in Figures 3 and 4, a test device for the production of inductive proximity sensors includes a test table 101, a support leg 102 is provided at the bottom of the test table 101, a placement slot 103 is provided at the top of the test table 101, four side ends of the placement slot 103 are laterally provided with first telescopic push rods 104, the inner ends of the output shafts of the four first telescopic push rods 104 are respectively provided with positioning plates 105, the bottoms of the four positioning plates 105 are respectively provided with supporting sliders 106, the bottom of the placement slot 103 is provided with supporting slide grooves 107 respectively matched with the four supporting sliders 106, vertical rods 108 are also provided at the top corners of the test table 101, a top plate 109 is commonly provided on the tops of the four vertical rods 108, and a lifting and movable test module is provided at the bottom of the top plate 109. Through the cooperation of the support slide groove 107 and the support slider 106, the movement of the positioning plate 105 can be guided and supported, avoiding the positioning plate 105 being in a suspended state and causing the output shaft of the telescopic push rod to be deformed and damaged, thereby extending the service life of the first telescopic push rod 104.

[0025] like Figure 1 , 2As shown, the lifting and movable test module includes a first linear slide 201 which is arranged at the left and right side ends of the bottom of the top plate 109 and runs along the front-to-back direction, a second linear slide 202 which runs along the left-right direction is commonly arranged at the bottom of the slide seats of the two first linear slides 201, a second telescopic push rod 203 is vertically arranged at the bottom of the slide seat of the second linear slide 202, a mounting plate 204 is arranged at the lower end of the output shaft of the second telescopic push rod 203, and a plurality of detection probes 205 are arranged at the bottom of the mounting plate 204.

[0026] like Figure 3 As shown, a control panel 110 is also provided on the test bench. The control panel 110 is electrically connected to the four first telescopic push rods 104, the two first linear slides 201, the second linear slide 202 and the multiple detection probes 205 respectively. The control panel 110 is also provided with a display area 111 for displaying the test results.

[0027] The user can use the placement guide of the four positioning plates 105 to quickly and accurately place the proximity sensor to the corresponding position in the placement slot 103, and then the position of a detection probe 205 can be adapted to the plug-in part of the proximity sensor by moving the two first linear slides 201 left and right and the slide seat of the second linear slide 202 forward and backward.
