A large cam 93 that acts on the pulley 64 is sleeved in the middle of the camshaft 91, and the wheel surfaces of the two are in contact with each other. A connecting gear 94 is also sleeved on the camshaft 91, and a driving gear 95 is meshed on one side of the connecting gear 94. The driving gear 95 is sleeved on the output shaft of the uniform speed motor 96, and the uniform speed motor 96 is fixed inside the mounting seat 6.

[0062] Furthermore, a support platform 88 is fixed to the outer side of the detection platform 1, and an operation panel and a display 82 are arranged on the support platform 88. Figure 1 and Figure 4 shown.

[0063] Furthermore, a first side baffle 81 acting on the circuit breaker 4 is symmetrically arranged at the edge of the upper end surface of the detection platform 1, and the first side baffle 81 plays a role of limiting and guiding. Figure 1 shown.

[0064] When the present embodiment is in use, a plurality of groups of circuit breakers 4 are first placed on the conveyor 2 in sequence, and move along with the belt 3 toward the detection platform 1 until the front group of circuit breakers 4 contacts the first side baffle 81, at which time the servo motor 18 is started, and the No. 1 rotating shaft 16 drives the first gear 15 to rotate, and when the first gear 15 rotates, the push rod 11 is driven to move linearly to the right along the slide slot 12, and the push connecting piece 14 contacts the surface of the circuit breaker 4, pushing the circuit breaker 4 to move linearly to the right, and is transferred from the belt 3 to the upper end surface of the detection platform 1, and the circuit breaker 4 continues to move right on the upper end surface of the detection platform 1.

[0065] At this time, the uniform speed motor 96 on the cam driver 9 is started to drive the gear 95 to rotate, and the connecting gear 94 is driven to rotate through meshing reduction, and the large cam 93 coaxial with the connecting gear 94 makes a circular motion. When the protruding part of the large cam 93 moves to the top and contacts the pulley 64, the two generate an extrusion force to cause the pulley seat 63 and the lifting column 60 to move upward (causing the return spring 62 to be compressed), thereby causing the sampling tube 54 to move upward, and the sealing cover 55 to rise to the right end surface area of ​​the detection platform 1, blocking and positioning the forward route of the circuit breaker 4, and allowing the sealing cover 55 to buckle at the position of the ventilation hole 5 to form a seal. At this time, the power connection hole and the load connection hole of the circuit breaker 4 are respectively aligned with the two groups of storage holes 85, and then the power connector 83 and the load connector 84 are extended out of the storage hole 85 and inserted into the corresponding power connection hole and load connection hole, so that the circuit breaker 4 is located on the simulated detection circuit to test whether the circuit breaker 4 can light up normally.

[0066] The circuit breaker 4 is powered on for a period of time, and the suction pump 42 is started. The hot air (also called sampled air) inside the circuit breaker 4 is sucked from the ventilation hole 5 by the air inlet 56, and the hot air passes through the sampling tube 54 and the bellows 53 in sequence and enters the air sampling box 41. Then, the sampled air is slowly introduced into the air storage bag 46 through the compressed air pipe 45, so that the air storage bag 46 begins to inflate. The temperature and humidity of the sampled air are measured by the probes of the temperature sensor 47 and the humidity sensor 48 respectively, and the internal environment state of the circuit breaker 4 when working normally is tested. The data is displayed on the external display 82, and then the solenoid valve 51 is opened. The sampled air in the air storage bag 46 is slowly discharged outward through the exhaust pipe 50. Under the cooperation of the deformation force of the air storage bag 46 itself and the restoring force of the two sets of tension springs 49, the air storage bag 46 exhausts the internal air and returns to the dry and contracted state. The sampled air flowing in the exhaust pipe 50 passes through the limestone filter layer, so that the moisture in the air is absorbed by the limestone.

[0067] By starting the screw motor 68, the small gear 67 is driven to rotate, and the large gear 66 is driven to rotate through meshing reduction, causing the bidirectional screw 31 to rotate, causing the two sets of connecting seats 36 at the positions of the positive threaded portion 33 and the reverse threaded portion 34 to move toward each other (the screw nut in the screw nut sleeve 35 moves at the threaded portion position), and the rough surface 39 of the clamping plate 37 is used to contact the side of the circuit breaker 4 on the test bench 1. The two sets of clamping plates 37 clamp the circuit breaker 4. When the No. 1 rotating shaft 16 rotates, the No. 1 sprocket 19 on the No. 1 rotating shaft 16 moves accordingly, and is connected and transmitted through the synchronous chain 22, so that the No. 2 sprocket 21 moves, and the No. 2 sprocket 21 is connected to the No. 1 rotating shaft 16. The second gear 23 coaxial with the sprocket 21 rotates, causing the displacement seat 24 to which the second tooth portion 27 belongs to move linearly to the right along the track groove 25, that is, to keep synchronous movement in the same direction as the push rod 11, so that the bent connecting arm 28 pulls the entire clamping seat 30 to move to the right, and the circuit breaker 4 that has been tested in the clamping seat 30 passes over the mounting seat 6 (under the dual conditions that the power connector 83 and the load connector 84 are recovered into the storage hole 85 and the sealing cover 55 returns to its downward position), and is transferred to the top of the assembly line conveyor. At this time, the two sets of clamps 37 are released to allow the circuit breaker 4 to fall into the assembly line conveyor, forming a continuous pushing and unloading operation. Embodiment 2

[0068] Based on the first embodiment, the power connector 83 and the load connector 84 are generally inserted into the corresponding power connector and load connector by manual operation, which is time-consuming and labor-intensive, has a low degree of automation, and the plugging and unplugging force cannot be accurately controlled. In order to solve the above technical problems, we have the following design, such as Figure 11-13 shown.

[0069] Specifically, a cylindrical receiving groove 70 is provided inside the testing platform 1 and directly below the two groups of receiving holes 85. A moving roller 71 is movably provided in the cylindrical receiving groove 70. Bar grooves 72 are symmetrically provided on both sides of the moving roller 71. Limiting blocks extending into the bar grooves 72 are installed on the side walls of the cylindrical receiving groove 70 to play a role of limiting and guiding. Fig.11 and Fig.12 shown.

[0070] One end of the moving roller 71 is fixedly connected to the groove wall of the cylindrical receiving groove 70 through the connecting spring 73. Fig.12 shown.

[0071] The end of the moving roller 71 away from the connecting spring 73 is provided with an arc portion 74, and the arc portion 74 extends outward from the outer side of the detection platform 1 in a natural state. The upper end of the displacement seat 24 is provided with a guide wheel 75 acting on the arc portion 74. Fig.11 and Fig.12 shown.

[0072] Furthermore, two groups of inclined grooves 76 are provided on the upper end surface of the moving roller 71, and slopes 77 are provided at the bottom of the two groups of inclined grooves 76 (one side of the slope 77 is high and the other side is low), and traction structures 78 are installed in the two groups of inclined grooves 76. Fig.12 shown.

[0073] Specifically, the traction structure 78 includes a lifting rod 781, a spring sleeve 782, an insulating roller 783, a compression spring 784 and a joint assembly groove 785. Fig.13 shown.

[0074] In this embodiment, the lower end of the lifting rod 781 is located in the inclined groove 76, and a spring sleeve 782 is fixed to the upper end of the lifting rod 781. An insulating roller 783 is fixed to the middle of the upper end surface of the spring sleeve 782. The insulating roller 783 is made of insulating material. A compression spring 784 is fixed between the spring sleeve 782 and the bottom of the storage hole 85 and is sleeved on the outside of the insulating roller 783 (the compression spring 784 is used to maintain the contact force between the lifting rod 781 and the slope 77). A connector assembly groove 785 is provided inside the insulating roller 783, which acts on the power connector 83 and the load connector 84 respectively, and the insulating roller 783 moves in the storage hole 85.

[0075] When the present embodiment is in use, after the push rod 11 pushes the circuit breaker 4 to the specified position, the servo motor 18 moves in the reverse direction, the push rod 11 returns to the left, and at the same time, the No. 1 rotating shaft 16 undergoes a series of transmissions to make the displacement seat 24 return to the left along the track groove 25 in a straight line. When the displacement seat 24 is close to the initial movement position, the guide wheel 75 on the displacement seat 24 contacts the arc portion 74 of the moving roller 71, generating a mutual force, pushing the moving roller 71 in the cylindrical receiving groove 70 to move inward in a straight line for a distance (causing the connecting spring 73 to be compressed), thereby causing the two sets of traction structures 78 to move in the inclined groove 76 respectively, and the bottom of each set of lifting rods 781 slides relatively along the slope 77, causing the lifting rods 781 to carry The movable insulating roller 783 moves upward, and the insulating roller 783 moves in the connector assembly groove 785 (the compression spring 784 is squeezed and compressed), driving the power connector 83 and the load connector 84 upward through the storage hole 85, and automatically inserting them into the corresponding power connection hole and load connection hole; when the displacement seat 24 starts to move to the right, thereby separating the guide wheel 75 and the movable roller 71, the movable roller 71 returns to its original position under the expansion elastic force of the connecting spring 73, and the lifting rod 781 loses its restraint. Under the action of the restoring elastic force of the compression spring 784, the lifting rod 781 and the insulating roller 783 return downward, so that the power connector 83 and the load connector 84 are pulled out of the connector hole and return to the storage hole 85 respectively.
