[0048] This application provides Figure 1-12 The technical solution of the circuit breaker automatic wiring tool shown in the embodiment is as follows:

[0049] The circuit breaker automatic wiring tool comprises a frame 30, a first wiring device 10 and a second wiring device 20 respectively arranged at the upper and lower parts of the frame 30; the first wiring device 10 comprises a first clamping mechanism 110 and a first orientation adjustment mechanism 120; the second wiring device 20 comprises a second clamping mechanism 210 and a second orientation adjustment mechanism; the first clamping mechanism 110 and the second clamping mechanism 210 both comprise clamping claws; the clamping claws comprise two facing clamping plates 111, and a clamping drive mechanism 115 for driving the two clamping plates 111 to move closer or further away; wherein the clamping claws The plate 111 is made of insulating material, and conductive contacts 112 are provided on the lower parts of the opposite sides of the two clamping plates 111; the first orientation adjustment mechanism 120 is used to drive the first clamping mechanism 110 to move up and down, so that the two conductive contacts 112 of the first clamping mechanism 110 can clamp the circuit breaker contacts to be connected to the circuit breaker contacts; the second orientation adjustment mechanism is used to drive the second clamping mechanism 210 to move up and down, front and back, and left and right, so that the two conductive contacts 112 of the second clamping mechanism 210 can clamp the circuit breaker contacts to be connected to the circuit breaker contacts.

[0050] Wherein, for the second orientation adjustment mechanism, optionally, the second orientation adjustment mechanism comprises a three-direction motion mechanism combination, a whole machine propulsion mechanism 230; a plurality of second clamping mechanisms 210 are fixedly connected on the three-direction motion mechanism combination, so that the three-direction motion mechanism combination drives the second clamping mechanisms 210 to move up and down, forward and backward, and left and right; the whole machine propulsion mechanism 230 comprises a main plate 232 for loading the three-direction motion mechanism combination, a first X-axis guide rail 233, and a second driving component 231; the rack 30 is provided with the first X-axis guide rail 233 extending in the forward and backward direction, the bottom surface of the main plate 232 is provided with a first X-axis sliding block 234, the first X-axis sliding block 234 is in sliding connection with the first X-axis guide rail 233, and the output end of the second driving component 231 is fixedly connected with the main plate 232, so that the second driving component 231 drives the main plate 232 to move forward and backward, so as to drive the whole three-direction motion mechanism to move forward and backward. Further optionally, the three-direction motion mechanism combination comprises a height switching mechanism 240 and a two-direction motion mechanism combination; the height switching mechanism 240 is coupled above the main plate 232, the two-direction motion mechanism combination is coupled above the height switching mechanism 240, a plurality of third clamping mechanisms 220 are connected on the height switching mechanism 240, and a plurality of second clamping mechanisms 210 are connected on the two-direction motion mechanism combination; wherein, the height switching mechanism 240 drives the third clamping mechanisms 220 and the two-direction motion mechanism combination to move up and down, and the two-direction motion mechanism combination drives the second clamping mechanisms 210 to move forward and backward and left and right, so that the second clamping mechanisms 210 can move forward and backward, left and right, and up and down. Further optionally, the third clamping jaw 110c comprises two opposite clamping plates 111 and a clamping driving mechanism 115 for driving the two clamping plates 111 to approach or move away from each other; wherein, the clamping plates 111 are made of insulating material, and the opposite side surfaces of the two clamping plates 111 are provided with conductive contact blocks 112 at the lower part;

[0051] Specifically, the circuit breaker automatic wiring tool provided by the embodiment of the present application is suitable for automatic wiring of ZW32 and ZW20 type circuit breakers. During use, due to the size difference of the circuit breakers, the orientation of the clamping jaws (first clamping jaw 110a, second clamping jaw 110b, third clamping jaw 110c) of the clamping mechanisms (first clamping mechanism 110, second clamping mechanism 210, third clamping mechanism 220) is adjusted through the first orientation adjustment mechanism 120 and the second orientation adjustment mechanism, so as to accurately position them, and the conductive contact blocks 112 of the two clamping plates 111 of the clamping jaws are brought close to clamp the contacts of the circuit breakers;

[0052] The two clamping plates 111 of the clamping jaws (first clamping jaw 110a, second clamping jaw 110b, and third clamping jaw 110c) are made of insulating material, and the conductive contacts 112 are made of conductive material (including but not limited to copper) for connecting external wires. As a result, when the conductive contacts 112 automatically clamp the contacts of the circuit breaker, the conductive contacts 112 and the external wires on the conductive contacts 112 cooperate to achieve automatic wiring of the circuit breaker contacts. In addition, except for the path between the conductive contacts and the external wires, the clamping plates 111 are made of insulating material to prevent the circuit breaker from forming an electrical connection with other components, facilitating circuit breaker testing.

[0053] In the embodiment of the present application, the orientation of the clamping mechanism's claws is adjusted through an orientation adjustment mechanism (a first orientation adjustment mechanism 120 and a second orientation adjustment mechanism) so that the clamping mechanism smoothly reaches a desired position. The claws then cooperate with the conductive contacts 112 on the two clamping plates 111 to automatically clamp the contacts of the circuit breaker, thereby achieving automatic wiring of the contacts of the circuit breaker for testing the circuit breaker. Furthermore, during the test, the use of the claws to clamp the contacts ensures stable wiring, good electrical contact, and a clear conductive path, thereby meeting the requirements of circuit breaker maintenance. The application of this tool in actual maintenance can save a lot of manpower, improve maintenance efficiency, and enhance the quality of test results.

[0054] It should be noted that:

[0055] The gripper described in the embodiment of the present application is an air gripper, that is, the clamping drive mechanism 115 that drives the two clamping plates 111 to move closer or further apart is a cylinder. The working principle of the air gripper, which is designed through structure and construction to enable the cylinder to drive the two clamping plates 111 to move closer or further apart, is prior art and will not be repeated here. The design concept of the present application is to design the insulating clamping plates 111 and the conductive contact blocks 112 in the gripper. Therefore, how to realize how the driving mechanism in the gripper drives the clamping plates 111 to clamp or release, those skilled in the art can select from existing automatically driven clamping grippers, including but not limited to air grippers.

[0056] Optionally, the first orientation adjustment mechanism 120 includes a frame 122 and a first driving component 121 fixedly connected to the top of the frame 30; the bottom surface of the frame 122 is fixedly connected to a plurality of first clamping mechanisms 110; the output end of the first driving component 121 is fixedly connected to the top of the frame 122, and is used to drive the frame 122 to move up and down, thereby driving the first clamping mechanism 110 to move up and down. Optionally, the first orientation adjustment mechanism 120 includes a frame 122, a fixed plate 123, a guide column 124, and a first driving component 121; the fixed plate 123 is fixedly connected to the frame 30, and the first driving component 121 is fixedly connected to the fixed plate 123; the output end of the first driving component 121 and the bottom of the guide column 124 are fixedly connected to the top of the frame 122; a linear bearing 1231 matching the guide column 124 is provided on the fixed plate 123; wherein, the linear bearing 1231 is mounted on the guide column 124, so that the first driving component 121 drives the frame 122 to move up and down, and the guide column 124 slides up and down in the linear bearing 1231.

[0057] During use, the output end of the first drive component 121 drives the frame 122 to move up and down, thereby driving the first clamping mechanism 110 to move up and down. Furthermore, through the design of the fixed plate 123 and the guide post 124, during use, the output end of the first drive component 121 applies force to the frame 122, driving it up and down, causing the guide post 124 to slide up and down within the linear bearing 1231 of the fixed plate 123. This design ensures more stable up and down movement of the entire plane of the frame 122, preventing the frame 122 from shaking or tilting in the front, back, left, or right directions.

[0059] The design of providing the spring floating mechanism 113 on the first clamping mechanism 110 and the elastic block 114 on the second clamping mechanism 210 and the third clamping mechanism 220 allows the first clamping mechanism 110, the second clamping mechanism 210, and the third clamping mechanism 220 to play a certain buffering role when contacting the circuit breaker when they are driven to the circuit breaker contact positioning area for clamping, thereby preventing the circuit breaker from being damaged by severe collision when contacting the clamping mechanism;

[0060] In addition, the spring floating mechanism 113 of the first clamping mechanism 110, the elastic block 114 of the second clamping mechanism 210, and the third clamping mechanism 220 are designed to be made of insulating materials to further prevent the circuit breaker from forming an electrical connection with other components except for the conductive contacts and external wires, thereby facilitating testing of the circuit breaker.

[0064] When in use, the second position adjustment mechanism operates as follows:

[0065] The operation process of the whole machine propulsion mechanism 230 is as follows: the output end of the second driving component 231 is fixedly connected to the main board 232, so that the second driving component 231 drives the first X-axis slider 234 of the main board 232 to slide back and forth on the first X-axis guide rail 233, so that the main board 232 slides back and forth, thereby driving the three-directional motion mechanism (including the first carrier plate 242, the second carrier plate 252, the third carrier plate 262 and the second clamping mechanism 210 and the third clamping mechanism 220) thereon to move back and forth;
