[0020] like Figures 1 to 6As shown, the testing equipment for the switch spring in the micro switch provided by this utility model includes a base plate 1, a tooling stage 2, a slide cylinder 3, a vertical moving slide 4, a test head assembly 5, a horizontal moving slide 6, a micro motor 7, a sensor assembly 8, a sensing assembly 9, and a control console 10.

[0021] The substrate 1 provides the necessary fixed platform for the entire test equipment.

[0022] The tooling stage 2 is used to support and fix the microswitch to be tested, and is mounted on the base plate 1. For example... Figure 2 As shown, it includes a platform body 21 and positioning elements 22 and positioning pins 23 disposed around the platform body.

[0023] See Figures 3 to 5 The slide cylinder 2 provides power for the horizontal movement of the test head and is connected to the test head assembly 5 via the vertically moving slide 4. The vertically moving slide 4 includes a fixed side 41 and a moving side 42. The fixed side 41 is fixed to the position where the slide cylinder 3 extends outward, and a slide rail is provided on the fixed side 41. A groove is provided on one side of the moving side 42, allowing it to move vertically within the slide rail of the fixed side 41. The test head assembly 5 is located on the other side of the moving side 42. The test head assembly 5 includes a test head 51 and two adapters 52 and 53. The test head 51 is fixed to the moving side 42 of the vertically moving slide 4 via one adapter 52. It is fixed to the moving side 62 of the horizontally moving slide 6 via the other adapter 53. The moving side 62 of the horizontal moving slide 6 is also provided with a groove, and the fixed side 61 is provided with a slide rail. The sliding of the slide cylinder 3 can drive the horizontal moving slide 6 to slide, thereby causing the test head 51 to protrude above the switch spring (not shown in the figure) in the micro switch. The fixed side 61 of the horizontal moving slide 6 is fixed to the micro motor 7. The micro motor 7 here is a lead screw motor 72. The lead screw motor is fixed by the motor bracket 71 and is perpendicular to the base. Therefore, the lead screw motor 72 can drive the lead screw to work, causing the vertical moving slide 4 connected to the horizontal moving slide 6 and the test head assembly 5 to move up and down, thereby realizing the vertical movement of the test head 51. After the test head 51 is retracted, the switch spring is below it. The vertical movement of the test head 51 allows the switch spring to be pressed against by the test head 51.

[0024] The sensor assembly 8 is fixed on the base plate 1 and is used to detect the vertical movement distance of the test head assembly 5. Specifically, the sensor assembly 8 includes a fixing frame 81 and a GT2 sensor 82; wherein, the fixing frame 81 is fixed on the base plate 1, and 82 is fixed on the fixing frame, and the GT2 sensor 8 is located above the fixed side 41 of the horizontal moving slide 6. By detecting the vertical movement of the horizontal moving slide 6 (i.e., the test head 51), the vertical travel of the switch spring can be obtained.

[0025] like Figure 6 As shown, the sensing component 9 is disposed on the substrate 1, including a sensing base 91 and a sensing head 92; wherein, the sensing head is provided with three conductive rods 921 for detecting the upper and lower limits of the spring-loaded height of the three microswitches. To accommodate different models of microswitches, an extension member 93 can be added between the sensing head 92 and the sensing base 91 to increase the height of the sensing head 92. Furthermore, the positions of the sensing component 9 and the tooling stage 2 can be interchanged as needed to improve the adaptability of this invention.

[0026] The control console 10 is the control center of the entire testing equipment, which includes a programmable logic controller (PLC) 101, a human-machine interface 101, and indicator lights 102. The PLC is electrically connected to the slide cylinder 3, the micro motor 7, the sensor assembly 8, the sensing head 91 of the sensing assembly 9, the micro switch, the human-machine interface 101, and the indicator lights 102, respectively, for the logic control of each component. The specific control process will be described in detail below.

[0027] The working process of this utility model will be further described in detail below with reference to the accompanying drawings.

[0028] Before testing, the micro switch is assembled on the tooling table 2. The micro switch can be accurately assembled using the positioning parts 22 and 23 on the tooling table 2. The micro switch will then have wiring connected to the PLC of the testing equipment via a connector.

[0029] During testing, the equipment is powered on, and the PLC controls the slide cylinder 3 to extend, causing the horizontal sliding slide 6 to move forward. Since the vertical sliding slide 4 is on the slide cylinder 3, the vertical sliding slide 4 connected to the slide cylinder 3, as well as the test head 51, will all be pushed forward. After the slide cylinder 3 is extended to its position, the test head 51 will be located above the switch spring in the micro switch. Then, the PLC controls the micro motor to drive the lead screw. The fixed side 61 of the horizontal sliding slide 6 is fixed to the lead screw, and together with the vertical sliding slide 4, it drives the test head 51 to move downward, thereby pressing against the switch spring.

[0030] During the test, the micro motor 7 drives the test head 51 to move downwards gradually, which can simulate the up and down travel of the switch spring. At the same time, the GT2 sensor 82 detects the travel in real time, and the PLC displays the data read by the GT2 sensor 82 in real time on the human interaction interface 102.

[0031] When the test head 51 is pushed onto the switch spring of the micro switch, the conductive rod 921 on the sensing head 92 disconnects from the switch spring in the micro switch. The PLC records the test value. When any one of the three switch springs of the micro switch is triggered for the first time, and when all three are triggered, the PLC records the test value and calculates the height difference to determine the trigger height of the switch spring. Simultaneously, the PLC has a preset reference value for the switch spring. The detected value is compared with the reference value. If the test result is outside the reference value range, it is considered NG (Not Good), and the red indicator light illuminates, indicating that the product is unqualified. If the test result is within the reference value range, it is considered OK, and the green light illuminates, indicating that the product is qualified.

[0032] In summary, the testing equipment provided by this utility model achieves two main functions through an intelligent control system: first, automatic testing, which is achieved by the coordinated drive of the micro motor 7 and the slide cylinder 3 to realize the automated and precise execution of testing actions; second, data measurement and feedback, which uses the GT2 sensor 82 to complete the measurement of product parameters and provides real-time feedback of test results status through the indicator light 102.
