The incomplete gear 59 rotates continuously to drive the rectangular plate 502 to move up and down reciprocatingly, and the gear 56 is driven to rotate reciprocatingly through the rack 2 57.

[0061] Here’s how it works:

[0062] In the actual production process of intelligent circuit breakers, they need to be inspected, but manual inspection is inefficient and unsafe. In this embodiment, a stage 3 is used to fix the intelligent circuit breaker, and two rotatable rotating seats 35 are used to clamp the ends of the intelligent circuit breaker, and then the locking rod 33 is rotated, and the end of the locking rod 33 is pressed against the side of the intelligent circuit breaker to fix the intelligent circuit breaker.

[0063] Then the terminal in the detection slot 34 is pulled out, the terminal is connected to the intelligent circuit breaker, the circuit breaker action voltage detector is connected to the intelligent circuit breaker, and then the screw rod 22 is started to move the intelligent circuit breaker into the detection chamber 13.

[0064] When the intelligent circuit breaker is located below the monitoring chamber 15, the bidirectional motor 26 is started to control the two support blocks 21 to move toward each other, lift the loading platform 3, and slide the intelligent circuit breaker into the detection groove, abut against the inner wall of the detection groove to seal the detection groove. The intelligent circuit breaker enters the monitoring chamber 15, and then the circuit breaker action voltage detector tests the intelligent circuit breaker. The heat generated by the current when the intelligent circuit breaker is working is monitored by the temperature and humidity sensor in the monitoring chamber 15, and the heat changes generated when the intelligent circuit breaker is working are tested in real time.

[0065] After the temperature and humidity detection is completed, it is sent to the second detection slot for visual inspection of the panel of the intelligent circuit breaker, and the intelligent circuit breakers with damaged panels or those that do not meet product requirements are removed. Then it is sent to the third detection slot and the rectangular frame 17 is moved by the cylinder 2 18. The rectangular frame 17 pushes and squeezes the operating handle of the intelligent circuit breaker to simulate the manual operating handle. The manual operation part of the intelligent circuit breaker is tested, which eliminates the manual operation method and improves the safety of product testing. Under the monitoring of the circuit breaker action voltage detector, the working condition of the manual opening and closing of the intelligent circuit breaker can be detected, and the sensitivity of the opening and closing of the intelligent circuit breaker can be judged by voltage monitoring.

[0066] In the above process, the side wall of the circuit breaker can be pressure-tested synchronously, as follows: the lead screw 53 is controlled to rotate by the motor 2 to move the position of the cam 55 up and down, so that the cam 55 is located between the two levers 46, and then the cylinder 14 pushes the fixed plate 51 close to the intelligent circuit breaker, so that the cam 55 abuts against the lever 46, and the incomplete gear 59 is driven to rotate by the motor 3 590, and the incomplete gear 59 is meshed with the rack 3 58. The incomplete gear 59 continues to rotate to drive the rectangular plate 502 to move up and down reciprocatingly, and the gear 56 is driven to rotate reciprocatingly through the rack 2 57.

[0067] The cam 55 pushes the moving rod 41 to approach the intelligent circuit breaker, squeezes the side of the intelligent circuit breaker, and detects the pressure resistance performance of the intelligent circuit breaker. Then the spring 38 pulls the ring 37 to reset. The cam 55 rotates one circle to complete a cycle, and this cycle is repeated to continuously detect the intelligent circuit breaker, automatically test, and improve the safety and efficiency of detection.
