A contoured design based on the product's appearance ensures the product is securely fixed between the upper and lower pressure plates, and that the spring-loaded ejector pins make good contact with the test points on the PCB. The control board then performs high-speed automatic functional tests on the module.

[0003] Currently, existing testing equipment lacks sufficient safety during operation. If an object or hand accidentally enters the working area of ​​the testing instrument, it can easily cause safety hazards and is detrimental to safe production. Utility Model Content

[0004] The purpose of this utility model is to provide a hand-protection structure for testing electronic control module circuit boards, aiming to solve the problem that existing equipment is not safe enough during operation. If an object or hand is accidentally put into the working area of ​​the testing instrument, it can easily cause safety hazards and is not conducive to safe production.

[0005] To achieve the above objectives, this utility model provides a hand-protection structure for detecting electronic control module circuit boards, including a device body, a detection mechanism on the device body, and a protective mechanism.

[0006] The protective mechanism includes a positioning block, a mounting box, a safety light curtain, a locking block, a fixing plate, a limiting post, a locking nut, and an operating device. The positioning block is detachably connected to the equipment body and is symmetrically arranged. The mounting box is detachably connected to the positioning block and is located on one side of the positioning block. The safety light curtain is detachably connected to the mounting box and electrically connected to the equipment body. The locking block is detachably connected to the housing of the safety light curtain, and two are arranged vertically. The fixing plate is detachably connected to the mounting box and is located on the side of the mounting box near the locking block. The limiting post is integrally formed with the fixing plate and is slidably connected to the locking block. The locking nut is threadedly connected to the limiting post and abuts against the uppermost locking block. The operating device is located on the front and right sides of the equipment body.

[0007] The operating device includes a start button and an emergency stop button. The start button is symmetrically arranged on the front side of the device body, and the emergency stop button is arranged on the right side of the device body.

[0008] The testing mechanism includes a lower gauge and a cooperating device. The lower gauge is disposed on the worktable of the equipment body, and the cooperating device is disposed on the upper side of the lower gauge.

[0010] A cooling fan is provided on the interface board at the rear of the device body.

[0011] This utility model discloses an anti-pinch structure for detecting electronic control module circuit boards. During processing, the circuit board is fixed and detected by a detection mechanism. Simultaneously, a safety light curtain provides protection during detection. When an operator's limb or arm enters the sensing area of ​​the safety light curtain during processing, the control system cuts off the power to the corresponding moving component of the equipment, and the component stops moving. This avoids potential safety hazards if an object or hand accidentally enters the working area of ​​the testing instrument. It also solves the problem of insufficient safety in existing equipment during operation, which can easily cause safety hazards if an object or hand accidentally enters the working area of ​​the testing instrument, thus hindering safe production.

It is understood that the aforementioned solution is more conducive to safe production.

[0021] In this embodiment, a detection mechanism is provided on the device body 101, which is used to fix and detect the circuit board.

[0022] The positioning block 102 is detachably connected to the device body 101 and is symmetrically arranged. The mounting box 103 is detachably connected to the positioning block 102 and is located on one side of the positioning block 102. The safety light curtain 104 is detachably connected to the mounting box 103 and is electrically connected to the device body 101. The locking block 105 is detachably connected to the housing of the safety light curtain 104 and two are arranged vertically. The fixing plate 106 is detachably connected to the mounting box 103 and is located on the side of the mounting box 103 near the locking block 105. The limiting post 107 is integrally formed with the fixing plate 106 and is slidably connected to the locking block 105. The locking nut 108 is threadedly connected to the limiting post 107 and abuts against the uppermost locking block 105. The operating device is located on the front and right sides of the device body 101. The positioning block 102 is fixed by bolts, and the mounting box 103 is connected to the positioning block 102 by bolts. The locking block 105 is fixed to the housing of the safety light curtain 104 by bolts and is provided with a U-shaped locking groove. The fixing plate 106 is fixed by bolts, and the fixing plate 106 is integrally vertically provided with the limiting post 107. The bottom of the limiting post 107 is provided with two spaced cards to form a locking groove to slide with the lower locking block 105, and the top is provided with a single card to cooperate with the upper locking block 105. The locking nut 108 is directly installed on the external thread end of the top of the limiting post 107. The operating device is used for equipment operation. A removable sealing plate is installed on the mounting box 103 by bolts.

[0023] Secondly, the start buttons 109 are symmetrically arranged on the front side of the device body 101; the emergency stop button 110 is located on the right side of the device body 101. The purpose of having two start buttons 109 is that the device needs to be pressed simultaneously to start, further preventing the operator's free arm from entering the device's working area during operation. The emergency stop button 110 is used for emergency stopping of the device.

[0024] Then, the lower inspection fixture 111 is set on the worktable of the equipment body 101; the mating device is set on the upper side of the lower inspection fixture 111. The lower inspection fixture 111 is used for circuit board placement support, and the mating device is used for inspection and mating.

The cylinder output end is connected to the upper inspection fixture 112, and the solenoid valve is used for cylinder reversing control.

[0026] Finally, a cooling fan 114 is provided on the interface board on the rear side of the device body 101.

[0027] This invention addresses the safety concerns of existing equipment, where accidental entry of objects or hands into the testing instrument's working area poses a significant safety hazard and compromises safe production. During processing, the circuit board is fixed and tested via the aforementioned detection mechanism. Simultaneously, the safety light curtain 104 provides protection during testing. When an operator's limbs or arms enter the sensing area of ​​the safety light curtain 104 during processing, the control system cuts off the power to the corresponding moving components of the equipment body 101, stopping their movement. This prevents accidental entry of objects or hands into the testing instrument's working area. Furthermore, the two start buttons 109 require simultaneous pressing to activate the device, further preventing unused arms from entering the working area. This effectively solves the safety issues inherent in existing equipment, addressing the problem of accidental entry of objects or hands into the testing instrument's working area.
