Description

Technical Field

[0001] This invention relates to the field of circuit breaker technology, and in particular to an automatic processing equipment for circuit breaker accessories. Background Technology

[0002] Molded case circuit breakers (MCCBs) automatically disconnect the current when the current exceeds the trip setting. An MCCB consists of a housing made of plastic insulator and control components housed inside the housing. MCCBs typically include two functions: overload delay protection and short-circuit instantaneous protection. Overload delay protection works by thermally deforming the bimetallic strip. When the circuit breaker is overloaded, overheating causes the bimetallic strip to bend and deform, triggering the tripping rod to rotate and trip. This tripping mechanism usually has an adjustable rod with a bevel on the tripping rod. The lateral position of the adjusting rod is adjusted by a knob, thus adjusting the distance between the bevel and the adjusting screw on the bimetallic strip. Short-circuit instantaneous protection works by the sudden increase in current during a short circuit, causing the moving and stationary iron cores on the tripping rod to separate, thereby breaking the circuit.

[0003] However, in actual use, the inventors found that the traditional manual assembly of the contact assembly was quite troublesome. First, the moving contact assembly was assembled into the housing, and the moving contact was manually tilted upwards to facilitate the insertion of the moving contact into the stationary contact assembly. Then the stationary contact assembly was assembled into the housing. This process was time-consuming and labor-intensive, resulting in low circuit breaker assembly efficiency. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing an automatic circuit breaker contact processing device. This device can drive the moving contact to tilt upwards at a specified angle and automatically insert it into the stationary contact housing. This facilitates the assembly of the stationary contact assembly, provides better positioning, higher assembly accuracy, saves manpower, and improves the assembly efficiency of circuit breakers.

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0038] Example 1 like Figures 1-17 As shown, an automatic processing equipment for circuit breaker accessories is provided. The circuit breaker includes a housing 7, and a moving contact assembly 8 and a stationary contact assembly 9 installed inside the housing 7. The moving contact assembly 8 includes a support shaft 81, several sets of moving contact supports 82 hinged to the support shaft 81, a moving contact 83 on the moving contact support 82, a braid 84 at one end of the moving contact 83, a terminal 85 at one end of the braid 84, and several sets of anti-slip clamps 86 on the support shaft 81. The stationary contact assembly 9 includes a stationary contact housing 91, a stationary contact 92 disposed on the stationary contact housing 91, a slot 93 formed on the stationary contact housing 91 for inserting the moving contact 83 into the interior of the stationary contact housing 91, and two sets of limiting grooves 94 disposed on the stationary contact housing 91. The housing 7 has several sets of moving contact mounting chambers 71, several sets of stationary contact mounting chambers 72, and several sets of wire braid mounting chambers 73 respectively. The inner wall of the stationary contact mounting chamber 72 is provided with a limiting strip 74 that slides and matches the limiting groove 94. The stationary contact mounting chamber 72 is provided with a stationary contact mounting seat 75. One side of the stationary contact mounting chamber 72 is provided with a strip-shaped clearance hole 76 for the moving contact 83 to rotate. A first strip-shaped bearing hole 77 for supporting the bracket connecting shaft 81 is provided on the side plate between two adjacent sets of moving contact mounting chambers 71, and the anti-slip clamp is clamped on the side plate between two adjacent sets of moving contact mounting chambers 71. The braid mounting chamber 73 has a second strip-shaped bearing hole 78 for supporting the braid 84 on one side wall, and a terminal mounting base 79 is provided inside the braid mounting chamber 73. The assembly equipment includes a feeding mechanism 2, a moving contact assembly mechanism 3, a stationary contact assembly mechanism 4, which are arranged sequentially along the circumferential direction on the frame 1, and a turntable mechanism 6 arranged on the frame 1 for carrying the housing to transfer between different workstations. The stationary contact assembly mechanism 4 includes a conveying assembly 41 disposed on the outside of the frame 1 for providing stationary contact assemblies, a clamping assembly 42 disposed on the frame 1 for clamping stationary contact assemblies, a flipping assembly 43 disposed on the clamping assembly 42 for driving the moving contact to rotate by a specified angle, and a winding assembly 44 disposed on the clamping assembly 42 for organizing the wire braids. The conveying assembly 41 intermittently provides the stationary contact assembly, the clamping assembly 42 clamps and assembles the stationary contact assembly into the stationary contact mounting chamber of the housing, the flipping assembly 43 drives the moving contact bracket to rotate the moving contact upward by a specified angle, before the stationary contact assembly is assembled into the stationary contact mounting chamber, the moving contact is inserted into the inside of the stationary contact housing through the strip hole, and the winding assembly 44 organizes the braids in the braid mounting chamber.

[0039] In this embodiment, the stationary contact assembly mechanism 4 and the moving contact assembly mechanism 3 work together to achieve the following: First, when assembling the stationary contact assembly, the moving contact is driven to tilt upwards at a specified angle and automatically inserted into the stationary contact housing. This not only facilitates the assembly of the stationary contact assembly within the housing but also the assembly between the stationary and moving contact assemblies. The positioning effect is good, the assembly accuracy is high, and the assembly effect of the circuit breaker is improved. Second, the moving and stationary contact assemblies are automatically assembled sequentially, resulting in orderly assembly work, high automation, reduced manpower, and improved assembly efficiency of the circuit breaker. This allows for continuous batch assembly of circuit breakers, increasing the economic benefits for the enterprise.

[0040] In detail, firstly, the turntable mechanism 6 rotates the positioning box 62 to the station of the feeding mechanism 2 and stops. The second transfer platform 24 transfers the housing to the station of the feeding mechanism 2 and stops. The feeding mechanism 2 transfers the housing into the positioning box 62 via the second electric gripper 23. Then, the turntable mechanism 6 carries the positioning box 62 to the station of the moving contact assembly mechanism 3 and stops. The third transfer platform 31 transfers the second carrier box 32, which temporarily stores the moving contact assembly, to the station of the moving contact assembly mechanism 3 and stops. The moving contact assembly mechanism 3 uses the third electric gripper 36 to clamp the anti-slip chuck on the support shaft of the moving contact assembly, and the wire-straightening assembly 37 holds the wire braid. The moving contact assembly is then lifted. During the assembly process, the straightening assembly 37 straightens the braid, facilitating its descent into the second strip-shaped bearing hole 78 of the braid mounting chamber 73. As the moving contact assembly is installed into the moving contact mounting chamber of the housing, the straightening assembly 37 drives one end of the braid towards the moving contact. Simultaneously, the pressing assembly 38 presses the braid down into the braid mounting chamber, causing it to fall in a V-shape. The braid is then secured in the second strip-shaped bearing hole 78 of the braid mounting chamber 73. At the same time, the terminal 85 falls onto the terminal mounting base 79 of the braid mounting chamber 73, completing the assembly of the moving contact assembly. Then, the turntable mechanism 6, carrying the positioning box 62, rotates to the stationary contact assembly... When the workstation of mechanism 4 stops, the first transfer platform 411 transfers the first carrier box 412, which temporarily stores the stationary contact assembly, to the workstation of the stationary contact assembly mechanism 4 and stops. The clamping assembly 42 transfers the stationary contact assembly to the stationary contact mounting chamber of the housing. During the process of the stationary contact assembly descending into the stationary contact mounting chamber, the clamp 4394 first elastically presses the anti-slip clamp of the bracket connecting shaft to prevent the bracket connecting shaft from rotating. At the same time, the pressure roller 448 elastically presses on the braid in the second strip-shaped carrier hole to prevent the braid from detaching from the second strip-shaped carrier hole. Then, the flipping assembly 43 drives the moving contact bracket to rotate the moving contact upward by a specified angle. The first hydraulic component 424 passes through the first electric gripper. 426 drives the stationary contact assembly to move horizontally to the position directly above the stationary contact mounting chamber, so that one end of the raised moving contact is inserted into the stationary contact cover 91 through the slot 93. Finally, the stationary contact assembly continues to descend into the stationary contact mounting chamber. The flipping assembly 43 does not drive the moving contact bracket to rotate the moving contact upward. Due to gravity and the downward movement of the stationary contact assembly, the moving contact rotates downward to reset until the stationary contact assembly is assembled into the stationary contact mounting chamber. At the same time, during the assembly of the stationary contact assembly, the winding assembly 44 organizes the wire braids into an S-shaped distribution inside the braid mounting chamber to prevent the wire braids from tangling, thus completing the assembly of the stationary contact assembly.

[0041] Furthermore, such as Figures 6-7 As shown, the turntable mechanism 6 includes a turntable 61 rotatably mounted on the frame 1 and several sets of positioning boxes 62 mounted on the turntable 61 and used to support the housing. A buffer pad is provided at the bottom of the positioning box 62.

[0042] It should be noted that the rotary table 61 is driven by an existing external motor, and the rotary table 61 intermittently carries the housing between different workstations.

[0043] Furthermore, such as Figure 6 and Figure 8 As shown, the feeding mechanism 2 includes: The second lifting unit 21 is mounted on the frame 1, and the structure of the second lifting unit 21 is the same as that of the first lifting unit 421. The second robotic arm 22 is located at the output end of the second lifting unit 21; The second electric gripper 23 is disposed at the output end of the second robotic arm 22; The second transfer platform 24 is disposed outside the frame 1 and is used to provide the housing.

[0044] It should be noted that the structure and function of the second robotic arm 22 and the second electric gripper 23 are existing technologies and will not be described in detail here.

[0045] In this embodiment, by cooperating with the loading mechanism 2 and the turntable mechanism 6, the housing on the second transfer platform 24 can be automatically transferred to the positioning box 62 of the turntable 61 to complete the automatic loading of the housing. Moreover, when the assembled circuit breaker returns to the position of the loading mechanism 2, the assembled circuit breaker can be transferred to the second transfer platform 24 to complete the automatic unloading of the circuit breaker.

[0046] In detail, the second lifting unit 21 drives the second electric gripper 23 to descend, and the second robotic arm 22 clamps the housing on the second transfer platform 24 through the second electric gripper 23 and transfers the housing into the positioning box 62 of the rotary table 61.

[0047] Furthermore, such as Figure 6 and Figures 9-12 As shown, the moving contact assembly mechanism 3 includes: The third transfer platform 31 is located outside the frame 1 and is used to provide the moving contact assembly. A second carrier box 32 for temporarily storing the moving contact assembly is placed on the third transfer platform 31. The third lifting unit 33 is mounted on the frame 1, and the structure of the third lifting unit 33 is the same as that of the first lifting unit 421. The third robotic arm 34 is disposed at the output end of the third lifting unit 33; The second hanger 35 is disposed at the output end of the third robotic arm 34; The third electric gripper 36, several sets of the third electric gripper 36 are arranged on the second hanger 35, and the third electric gripper 36 is used to clamp the anti-slip chuck on the bracket connecting shaft. A wire straightening assembly 37 is mounted on the second hanger 35 and is used to clamp and pull the straight braid. A wire pressing assembly 38 is disposed on the wire straightening assembly 37 and is used to press the braid down into the braid mounting chamber.

[0048] In this embodiment, the moving contact assembly mechanism 3 and the turntable mechanism 6 work together to automatically assemble the moving contact assembly with accurate positioning, thereby positioning the moving contact assembly in the moving contact mounting chamber of the housing. On the other hand, they can clamp and pull the straight braid, facilitating the braid to fall into the second strip-shaped bearing hole of the braid mounting chamber, and press the braid down into the braid mounting chamber in a V-shape, facilitating the automatic and accurate assembly of the braid into the braid mounting chamber, preventing the braids from tangling together, and ensuring that the moving contact assembly can be assembled smoothly.

[0049] In detail, the third lifting unit 33 drives the third electric gripper 36 to lift and lower. The third robotic arm 34, through the third electric gripper 36, grips the anti-slip chuck on the bracket coupling, lifting the moving contact assembly on the third transfer platform 31 and transferring the moving contact assembly to the moving contact mounting chamber of the housing. During the lifting of the moving contact assembly, the wire straightening assembly 37 clamps the end of the wire braid near the terminal 85 and drives the terminal 85 away from the moving contact, straightening and tightening the wire braid to prevent the wire braids from tangling together. The lifting of the moving contact assembly is completed when it descends to the moving contact mounting chamber. During the assembly process, the wire-straightening assembly 37 drives the terminal 85 to approach the moving contact, and the wire-pressing assembly 38 presses the wire braid down in a V-shape into the wire braid mounting chamber, so that the wire braid is stuck in the second strip-shaped bearing hole 78 of the wire braid mounting chamber 73. The terminal 85 is assembled onto the terminal mounting seat 79 of the wire braid mounting chamber 73. At the same time, the moving contact assembly is assembled into the moving contact mounting chamber, and the bracket coupling 81 is stuck in the first strip-shaped bearing hole 77 on the side plate between two adjacent sets of moving contact mounting chambers 71. The anti-slip clamp is held on the side plate between two adjacent sets of moving contact mounting chambers 71.

[0050] Furthermore, such as Figures 10-11 As shown, the wire straightening assembly 37 includes: Extension frame 371, a plurality of the extension frames 371 are mounted on the second hanger 35; The upright 372 is slidably mounted on the extension frame 371. The extension frame 371 is provided with a second driving member 373, which is used to drive the upright 372 to translate. The second driving component 373 includes a second lead screw 3731 disposed on the extension frame 371, a second threaded block 3732 threaded on the second lead screw 3731, and a second motor 3733 disposed on the extension frame 371 and used to drive the second lead screw 3731. The upright 372 is disposed at the bottom of the second threaded block 3732. The fourth electric gripper 374 is disposed at the lower end of the upright 372 and is used to grip the braid.

[0051] In this embodiment, the straightening component 37 can automatically clamp and pull the straight braids to prevent them from tangling together, making it easy for the braids to be automatically and accurately assembled into the braid installation chamber.

[0052] In detail, when the third electric gripper 36 holds the moving contact assembly, the fourth electric gripper 374 holds the end of the wire braid near the terminal 85. When the starting contact assembly is hoisted, the second motor 3733 of the second drive unit 373 drives the second lead screw 3731 to rotate. The second lead screw 3731 drives the upright 372 to move the fourth electric gripper 374 through the second threaded block 3732, so that the fourth electric gripper 374 carries the wire braid connected to the terminal 85 away from the moving contact, thereby straightening and tightening the wire braid.

[0053] Furthermore, such as Figures 10-12 As shown, the crimping assembly 38 includes: The second hydraulic component 381 is mounted on the extension frame 371 via a lug plate. Fixing plate 382, ​​the fixing plate 382 is disposed at the output end of the second hydraulic component 381; A pressure plate 383 is slidably disposed at the bottom of the fixed plate 382 via a sliding groove, and a fourth elastic element 384 is provided between the pressure plate 383 and one end of the sliding groove. A limiting rail 385 is provided on the upright 372 and is used to drive the pressure plate 383 to move horizontally to avoid the upright 372.

[0054] In this embodiment, the pressure assembly 38 ensures that the braids can be accurately assembled into each braid mounting chamber, and that the braids are accurately locked in the second strip-shaped bearing hole 78 on one side wall of the braid mounting chamber 73 for supporting the braids 84, thereby improving the assembly accuracy of the braids.

[0055] In detail, during the process of the moving contact assembly descending into the moving contact mounting chamber, the second motor 3733 of the second drive unit 373 drives the second lead screw 3731 to move and reset the upright 372 in the opposite direction through the second threaded block 3732, so that the upright 372 brings the braid connected to the terminal 85 closer to the moving contact through the fourth electric gripper 374. At the same time, the second hydraulic unit 381 drives the pressure plate 383 to descend. The pressure plate 383 presses down on the braid, which falls into the braid mounting chamber in a taut V-shape, so that the braid is stuck in the second strip-shaped bearing hole 78 of the braid mounting chamber 73, and the terminal 85 is assembled onto the terminal mounting seat 79 of the braid mounting chamber 73.

[0056] Furthermore, such as Figure 6 and Figures 13-14 As shown, the conveying assembly 41 includes a first transfer platform 411 disposed on the outside of the frame 1 and a first carrier box 412 placed on the first transfer platform 411 for temporarily storing the stationary contact assembly. The clamping assembly 42 includes: The first lifting unit 421 is mounted on the frame 1; The first lifting unit 421 includes a threaded rod 4211 rotatably mounted on the frame 1, a lifting platform 4212 threaded onto the threaded rod 4211, and a stepper motor 4213 mounted on the frame 1 for driving the threaded rod 4211. The first robotic arm 422 is mounted on the lifting platform 4212. The first robotic arm 422 is disposed at the output end of the first lifting unit 421; The first hanger 423 is disposed at the output end of the first robotic arm 422; The first hydraulic component 424 is mounted on the first hanger 423; Connecting plate 425, wherein the connecting plate 425 is disposed at the output end of the first hydraulic component 424; A first electric gripper 426, and several sets of the first electric grippers 426 are disposed on the connecting plate 425.

[0057] In this embodiment, the conveying component 41 and the clamping component 42 work together to automatically lift and assemble the stationary contact component, which is highly automated and improves the assembly efficiency of the stationary contact component.

[0058] In detail, the stepper motor 4213 of the first lifting unit 421 drives the threaded rod 4211 to rotate. The threaded rod 4211 drives the first electric gripper 426 to lift and lower through the lifting platform 4212. The first robotic arm 422 uses the first electric gripper 426 to pick up the stationary contact assembly on the first transfer platform 411 and simultaneously transfers several sets of stationary contact assemblies to the respective stationary contact mounting chambers of the housing.

[0059] Furthermore, such as Figures 14-17 As shown, the flipping component 43 includes: Extension plate 431, and several sets of the extension plate 431 are disposed on the first hanger 423; A first lifting rod 432 is slidably disposed on the extension plate 431, and a first elastic element 433 is provided between the upper end of the first lifting rod 432 and the extension plate 431. The hanging plate 434 is disposed at the lower end of the first hanging rod 432, and the bottom of the hanging plate 434 is provided with a clearance notch 435 for avoiding the braid; Anti-slip wheels 436, two sets of anti-slip wheels 436 are rotatably mounted on the hanging plate 434, and are used to drive the moving contact bracket to rotate the moving contact upward by a specified angle; The first ratchet 437 and two sets of the first ratchet 437 are rotatably mounted on the hanging plate 434 and drive the anti-slip wheel 436 to rotate through the transmission of belt and pulley. U-shaped frame 438, the U-shaped frame 438 is disposed at the bottom of the extension plate 431, and a first rack 439 for driving the first ratchet 437 is disposed on the U-shaped frame 438; A horizontal plate 4391 is disposed between two adjacent extension plates 431; The second rod 4392 passes through and is slidably disposed on the horizontal plate 4391, and a second elastic element 4393 is provided between the upper end of the second rod 4392 and the horizontal plate 4391. A clamp 4394 is disposed at the lower end of the second rod 4392 and is used to press down the anti-slip clamp of the bracket connecting shaft.

[0060] It should be noted that during the process of the stationary contact assembly descending into the stationary contact mounting chamber, the bottom of the hanging plate 434 descends and abuts against the bottom of the stationary contact mounting chamber. The stationary contact assembly continues to descend, and the first rack 439 of the U-shaped frame 438 continues to descend. First, the first ratchet 437, driven by the first rack 439, rotates the anti-slip wheel 436. The anti-slip wheel 436 drives the moving contact bracket to rotate the moving contact upwards by a specified angle. Then, it waits for one end of the moving contact to be inserted into the stationary contact cover 91 through the slot 93. Afterwards, the first rack 439 continues to descend and disengage from the first ratchet 437. The first ratchet 437 no longer drives the moving contact to rotate. Due to gravity, the moving contact rotates downwards as the stationary contact assembly descends. Then, after the moving contact assembly is assembled, the first robotic arm 422 drives the first hanger 423 to rise and reset, and also raises the first rack 439. The rise of the first rack 439 will not drive the first ratchet 437 to rotate, and the first ratchet 437 will not drive the contact support to rotate the moving contact again.

[0061] In this embodiment, the rotating component 43 and the clamping component 42 work together to drive the moving contact to rotate upward and tilt up, making it easier for the moving contact to be inserted into the stationary contact cover 91 through the slot 93, which is beneficial for the assembly of the stationary contact assembly.

[0062] In detail, during the descent of the stationary contact assembly into the stationary contact mounting chamber, the clamp 4394 first elastically presses against the anti-slip chuck of the bracket connecting shaft to prevent the bracket connecting shaft from rotating. Then, the bottom of the hanging plate 434 descends and abuts against the bottom of the stationary contact mounting chamber. The first electric gripper 426 continues to descend with the stationary contact assembly, and the first rack 439 of the U-shaped frame 438 continues to descend. Driven by the first rack 439, the first ratchet 437 rotates the anti-slip wheel 436, which in turn drives the moving contact bracket to rotate. As the moving contact rotates upwards by a specified angle, the first hydraulic component 424 drives the connecting plate 425 to move the first electric gripper 426 horizontally, causing the first electric gripper 426 to move the stationary contact assembly horizontally to the position directly above the stationary contact mounting chamber, and causing one end of the raised moving contact to be inserted into the slot 93 of the stationary contact cover 91. The first electric gripper 426 continues to lower the stationary contact assembly. As the stationary contact assembly lowers, the moving contact rotates downwards due to gravity until the stationary contact assembly is assembled into the stationary contact mounting chamber.

[0063] Furthermore, such as Figures 15-17 As shown, the winding assembly 44 includes: The elastic telescopic member 441 is slidably disposed on the extension plate 431. The extension plate 431 is provided with a first driving member 442, which is used to drive the elastic telescopic member 441 to translate. The first driving component 442 includes a first lead screw 4421 disposed on the extension plate 431, a first threaded block 4422 threaded on the first lead screw 4421, and a first motor 4423 disposed on the extension plate 431 and used to drive the first lead screw 4421. The winding clamp 443 is disposed at the lower end of the elastic telescopic member 441 and is used to organize the braids in an S-shaped distribution inside the braid installation chamber; The second ratchet 444 is disposed on the elastic telescopic member 441; The second rack 445 is disposed on the extension plate 431 and is used to drive the second ratchet 444 to rotate. The third rod 446 passes through and is slidably disposed on the extension plate 431, and a third elastic element 447 is disposed between the upper end of the third rod 446 and the extension plate 431. Pressure roller 448 is disposed at the lower end of the third rod 446 and is used to press on the braid in the second strip-shaped bearing hole to prevent the braid from detaching from the second strip-shaped bearing hole.

[0064] It should be noted that the elastic telescopic component 441 consists of a telescopic rod and a spring.

[0065] In this embodiment, by using the winding assembly 44 and the clamping assembly 42 together, the braids inside the braid mounting chamber can be arranged in an S-shape during the assembly of the stationary contact assembly, preventing the braids from tangling.

[0066] In detail, during the process of descent and assembly of the stationary contact assembly into the stationary contact mounting chamber, the pressure roller 448 first descends and elastically presses onto the braid in the second strip-shaped bearing hole. The winding clamp 443 descends and abuts against the bottom of the braid mounting chamber, with the braid located between the two clamps of the winding clamp 443. Then, the extension plate 431 continues to descend, and the elastic telescopic member 441 retracts. At the same time, the first motor 4423 of the first drive member 442 drives the first lead screw 4421 to rotate. The first lead screw 4421 drives the elastic telescopic member 441 to translate the winding clamp 443 through the first threaded block 4422. During the translation, the second ratchet 444 on the elastic telescopic member 441 translates along the second rack 445. The second rack 445 drives the second ratchet 444 to rotate the winding clamp 443 180 degrees through the elastic telescopic member 441, so that the winding clamp 443 arranges the braid inside the braid mounting chamber into an S-shaped distribution.

[0067] Example 2 like Figure 18As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows: Furthermore, such as Figure 18 As shown, it also includes a pressing mechanism 5, which includes: The fourth lifting unit 51 is mounted on the frame 1, and the structure of the fourth lifting unit 51 is the same as that of the first lifting unit 421. The pressing mold 52 is disposed at the output end of the fourth lifting unit 51 and is used to press the moving contact assembly and the stationary contact assembly into place.

[0068] In this embodiment, the pre-assembled moving contact assembly and stationary contact assembly can be pressed into place by the press-fitting mechanism 5, thus completing the assembly of the circuit breaker.

[0069] Work process: First, the turntable mechanism 6 rotates the positioning box 62 to the station of the loading mechanism 2 and stops. The second transfer platform 24 transfers the housing to the station of the loading mechanism 2 and stops. The loading mechanism 2 transfers the housing into the positioning box 62 via the second electric gripper 23. Then, the turntable mechanism 6 carries the positioning box 62 to the station of the moving contact assembly mechanism 3 and stops. The third transfer platform 31 transfers the second carrier box 32, which temporarily stores the moving contact assembly, to the station of the moving contact assembly mechanism 3 and stops. The moving contact assembly mechanism 3 uses the third electric gripper 36 to clamp the anti-slip clamp on the support shaft of the moving contact assembly. The wire straightening assembly 37 holds the wire braid. During the lifting of the moving contact assembly, the wire straightening assembly 37 straightens the wire braid for easy lifting. The wire braid falls into the second strip-shaped bearing hole 78 of the wire braid mounting chamber 73. During the process of assembling the moving contact assembly into the moving contact mounting chamber of the housing, the wire straightening assembly 37 drives one end of the wire braid to move towards the moving contact. At the same time, the wire pressing assembly 38 presses the wire braid down into the wire braid mounting chamber, causing the wire braid to fall into the wire braid mounting chamber in a V-shape. The wire braid is then stuck in the second strip-shaped bearing hole 78 of the wire braid mounting chamber 73. Simultaneously, the terminal 85 falls onto the terminal mounting seat 79 of the wire braid mounting chamber 73, completing the assembly of the moving contact assembly. Then, the turntable mechanism 6, carrying the positioning box 62, rotates to the stationary contact assembly mechanism 4 and stops. The first transfer platform 411 transfers the first bearing box 41, which temporarily stores the stationary contact assembly, to the stationary contact assembly. When the stationary contact assembly mechanism 4 stops at its station, the clamping assembly 42 transfers the stationary contact assembly to the stationary contact mounting chamber of the housing. During the descent of the stationary contact assembly into the stationary contact mounting chamber, the clamp 4394 first elastically presses the anti-slip clamp of the bracket connecting shaft to prevent the bracket connecting shaft from rotating. At the same time, the pressure roller 448 elastically presses the braid in the second strip-shaped bearing hole to prevent the braid from detaching from the second strip-shaped bearing hole. Then, the flipping assembly 43 drives the moving contact bracket to rotate the moving contact upward by a specified angle. The first hydraulic component 424 drives the stationary contact assembly to move horizontally to the position directly above the stationary contact mounting chamber through the first electric gripper 426, so that one end of the raised moving contact is inserted into the stationary contact cover 91 through the strip hole 93. Inside, the stationary contact assembly continues to descend into the stationary contact mounting chamber. The flipping assembly 43 does not drive the moving contact bracket to rotate upwards with the moving contact. Due to gravity and the downward movement of the stationary contact assembly, the moving contact rotates downwards to reset until the stationary contact assembly is assembled into the stationary contact mounting chamber. At the same time, during the assembly of the stationary contact assembly, the winding assembly 44 organizes the wire braids into an S-shaped distribution inside the braid mounting chamber to prevent the wire braids from tangling. Finally, the turntable mechanism 6 carries the positioning box 62 to the station of the pressing mechanism 5 and stops. The fourth lifting unit 51 drives the pressing mold box 52 to descend, pressing the pre-assembled moving contact assembly and stationary contact assembly into place, completing the assembly of the circuit breaker.
