The height of the limit rod 214 corresponding to the counterweight block 213 from bottom to top increases successively. According to the distance required to move for each force value gear, the height of each limit rod 214 from the fixed seat 211 is set, and each counterweight block 213 is placed above the corresponding limit rod 214, thereby achieving different initial heights of different counterweight blocks 213. According to the height of different counterweight blocks 213, the configuration block 213 can be prevented from being affected by external force and contacting the adjacent counterweight block 3, ensuring that all counterweight blocks 3 can be contacted in turn after being pushed by the movable rod 2, thereby ensuring that different levels of pressure can be applied to the touch switch under the movable rod 2.

[0034] The driving device 221 drives the pressing device 223 to move the touch switch downward and continue to press downward, so that the pressing column 226 slides to the top of the sliding space until the pressure sensor 222 reaches a specific pressure, thereby realizing the pressing detection of the button in the test piece 4.

[0036] Therefore, by setting up two workstations, the pressing detection device 2 and the rotating detection device 3 are separated, and different detections can be performed on the two products simultaneously, thereby improving the detection efficiency.

[0037] Each workstation is also provided with a light detection assembly, which includes a camera device 41 arranged on the frame 1, a pull-up door 42 arranged on the frame 1 to cooperate with the manufacture of a darkroom, and a switching device 43 for supplying power to the test piece 4. The switching device 43 is arranged in the detection tooling 7. The camera device 41 is fixed on the frame 1 and arranged above the test piece 4 to photograph the test piece 4. The camera device 41 is electrically connected to the display of the general control center 8 to photograph and display the backlight condition of the test piece 4. The pull-up door 42 can be driven by a pneumatic device, and slide rails are arranged on both sides of the pull-up door 42. The slide rails are fixedly connected to the pull-up door 42 to realize the lifting and lowering control of the pull-up door 42. After the pull-up door 42 is lowered, it forms a darkroom together with the frame 1, and the test piece 4 is covered in the darkroom. Therefore, there is no need to set up a special backlight detection darkroom. The pull-up door 42 is used to cooperate with the frame 1 to manufacture the darkroom, thereby reducing costs. When testing pressing or rotating, there is no need to disassemble the testing tool 7. The Y-axis driving device is controlled to control the test piece 4 to move inward along the Y-axis, and then the pull-up door 42 is pulled down to create a darkroom environment for backlight testing. A switching device 43 is provided in the testing tool 7 to convert the electricity at the power supply of the main control center 8 into a corresponding voltage and provide it to the test piece 4 to make it emit light, and the camera device 41 is used to take pictures.

[0038] The detection tool 7 includes a tool base plate 71 and a positioning tool 72 disposed on the tool base plate 71 for fixing the test piece 4 . An IC card for detecting and matching the positioning tool 72 is disposed on the tool base plate 71 .

[0039] Each IC card corresponds to a detection tool 7. After the host computer in the main control center 8 selects the model, the test can only start after the IC card is scanned and matched successfully, so as to prevent the wrong detection tool from being replaced.

[0040] The pressure detection device 2 and the rotation detection device 3 are respectively arranged on the position adjustment mechanism through a quick-change structure. The quick-change structure includes a fixing plate, a pin and a screw. The fixing plate and the nut of the Z-direction driving device in the position adjustment mechanism are positioned and fixed by the pins and screws. The screws are convenient for disassembly and installation, and are convenient for disassembly, maintenance and adjustment of each detection device.

[0041] The pressure detection device 2 and the rotation detection device 3 are both provided with an adapter plate 81 and an air valve 83. The main control center 8 is respectively connected to the two adapter plates 81 and the two air valves 83 to realize power supply and air supply to the pressure detection device 2 and the rotation detection device 3. The adapter plate 81 is used to integrate the electrical connections on the detection devices. The electrical aspects of each detection device are connected to the main control center 8 through a connector, and the electrical connection or port on each detection device is realized by plugging and unplugging the connector. Similarly, the air valve 83 centrally controls the pneumatic connection on its corresponding detection device, so that the main air pump of the main control center 8 is connected to the air valve 83 to supply air.

[0042] The main control center 8 is also provided with an emergency stop button for controlling the entire device to stop working, so as to avoid accidents such as over-limit action of each drive component and collision.

[0043] Specifically, before testing the test piece 4, a pressure sensor is fixed on the Y-axis driving device, and the position adjustment mechanism drives the pressure sensor to move to the bottom of the pressure calibration component 21, and controls the pressure calibration component 21 to move downward, so that the measuring round head 2121 contacts the measuring plate, and continues to move downward until the movable rod 212 moves. The pressure value of the pressure sensor at this time is the force of the pressure calibration component 21 at this gear, and each time a counterweight block 213 is driven, it is recorded to obtain the force corresponding to each level of the counterweight block 213. This force is the force to push the pressure calibration component 21 at each gear. If the gear force needs to be adjusted, it can be achieved by replacing the counterweight block 213 to achieve pressure calibration of the pressure calibration component 21; When the test piece 4 needs to be inspected, the corresponding inspection tooling 7 is selected to position and fix the test piece 4, and the main connection port of the test piece 4 is connected to the adapter 43. This can provide power to the backlight function in the test piece 4, and can transmit the feedback signals of the knobs, buttons and touch switches in the test piece 4 to the host computer of the main control center 8, so as to know whether the functions of each switch are normal during the inspection.

[0044] After the upper computer in the main control center 8 is selected, the IC card 82 on the detection tool 7 is scanned by the scanner of the main control center 8. The detection can be started only after the match is successful, which can prevent the detection tool 7 from being replaced incorrectly and thus detecting the wrong product. The detection tool 7 is then fixed to the corresponding Y-axis drive device 52.

[0045] When the test piece 4 needs touch detection, it is adjusted to the bottom of the pressure calibration component 21 through the position adjustment mechanism, and the X-axis drive device and the Z-axis drive device are driven to make the measuring round head 2121 contact the test piece 4 and continue to move downward until the counterweight block 213 corresponding to the required gear pressure is moved, until the touch detection of each pressure is completed, it can also be moved to the bottom of the pressing column 226, and the pressing component 22 is controlled to move downward little by little until the required pressure is reached and the touch detection is completed.

[0046] When the test piece 4 needs to press the detection button, the position adjustment mechanism is controlled to move the test piece 4 to below the pressing column 226 or the measuring round head 2121, and then the pressing assembly 22 moves down until the required pressure is reached and stops, completing the pressing detection.

[0047] When the test piece 4 needs to be tested for rotation function, the testing tool 7 is switched to another station, and the position adjustment mechanism is driven to move the test piece 4 under the clamp 31, and then the electric rotating clamp is controlled to clamp and turn the knob on the test piece 4 to complete the rotation test.

[0048] When the backlight function of the test piece 4 needs to be tested, the Y-axis drive device is controlled to move the test piece 4 inward, and the pneumatic device that controls the pull-up door 42 is driven to lower the pull-up door 42 to create a darkroom environment. At this time, the main control center 8 is controlled to supply power to make the test piece 4 illuminate, and the camera device 41 is started to shoot and display it on the display screen of the main control center 8 to complete the backlight test; then the pull-up door 42 is raised, the position adjustment mechanism is reset, and after taking out the detection tooling 7, the test piece 4 is removed to complete the test.
