[0067] This embodiment provides an automated assembly device for circuit breaker contacts, such as Figure 1 and Figure 2 As shown, the automatic assembly equipment is used to assemble the moving conductor 6, the moving contact 7 and the insulating pull rod 8 in the circuit breaker contact into one body through the connecting pin shaft 9. The automatic assembly equipment includes a workbench 1, a positioning assembly 2, a first drive assembly 3, a second drive assembly 4 and a third drive assembly 5. Among them, the first drive assembly 3, the positioning assembly 2 and the second drive assembly 4 are arranged in sequence along the first direction and all three are arranged on the workbench 1. The positioning assembly 2 is used to position the moving conductor 6, the first drive assembly 3 is used to drive the moving contact 7 to move along the first direction and extend into the moving conductor 6, and the second drive assembly 4 is used to drive the insulating pull rod 8 to move in the opposite direction of the first direction and extend into the moving conductor 6. The moving conductor 6 can be fixed by the positioning assembly 2, and then the first drive assembly 3 and the second drive assembly 4 are used to drive the moving contact 7 and the insulating pull rod 8 to move respectively, so that the moving contact 7 and the insulating pull rod 8 extend into the moving conductor 6 in the first direction and the opposite direction of the first direction respectively, and the pin hole on the moving contact 7 and the pin hole on the insulating pull rod 8 are aligned. The third driving component 5 is used to drive the connecting pin 9 to move along the second direction and insert it into the pin hole of the moving contact 7 and the pin hole of the insulating pull rod 8. In this way, the third driving component 5 can be used to drive the connecting pin 9 to extend into the moving conductor 6 along the second direction and insert it into the pin hole of the moving contact 7 and the pin hole of the insulating pull rod 8, thereby achieving the purpose of assembling the moving contact 7 and the insulating pull rod 8 through the connecting pin 9, thereby improving the assembly efficiency.

[0068] The first direction described in this embodiment is Figure 1 and Figure 2 The direction indicated by the arrow P in the middle, the second direction is Figure 1 and Figure 2The directions indicated by the arrows S in the middle, wherein the first direction is in the same direction as the axial direction of the moving conductor 6 positioned on the positioning assembly 2, and the second direction is perpendicular to the first direction.

[0069] Combination Figure 3 As shown, the positioning assembly 2 in this embodiment includes a clamping mechanism 21 and a positioning plate 20. The positioning plate 20 is provided with a positioning hole 200 for cooperating with a connecting hole located at the end of the moving conductor 6, and the clamping mechanism 21 includes a first clamping seat 210, a second clamping seat 211, a first linear drive 212 and a second linear drive 213. The first clamping seat 210 is formed with a first clamping portion, and the second clamping seat 211 is formed with a second clamping portion, and the first clamping portion and the second clamping portion cooperate to clamp the moving contact 7. The first linear drive 212 is arranged on the workbench 1 and is used to drive the first clamping seat 210 to reciprocate along the third direction, and the second linear drive 213 is arranged on the workbench 1 and is used to drive the second clamping seat 211 to reciprocate along the third direction. The third direction is Figure 1 and Figure 2 The third direction is perpendicular to both the first direction and the second direction. During operation, the manipulator can grab the moving conductor 6 and place the moving conductor 6 at a predetermined position. The predetermined position can be determined by the control program of the manipulator or by setting a support structure on the workbench 1. Figure 3 As shown, in this embodiment, a positioning seat 22 is further provided on the workbench 1, and the upper end surface of the positioning seat 22 forms a support for the moving conductor 6, so that the manipulator can determine the placement height of the moving conductor 6. After the moving conductor 6 is placed in place, the first clamping seat 210 and the second clamping seat 211 are driven to move by the first linear driver 212 and the second linear driver 213 respectively, and the moving conductor 6 can be clamped and positioned by the first clamping seat 210 and the second clamping seat 211. In addition, the manipulator can also use a pin shaft to pass through the positioning hole 200 of the positioning plate 20 and extend into the opening on the moving conductor 6, so as to further ensure the stability of the moving conductor 6.

[0070] It should be noted that the first linear actuator 212 and the second linear actuator 213 in this embodiment are both slide cylinders, and a group of first electric push rods 214 are also arranged between the first moving seat 10 and the second moving seat 11, and the pressure force of the slide cylinder can be preset so that the first moving seat 10 and the second moving seat 11 have a tendency to move closer to each other. When the moving conductor 6 needs to be placed, the first electric push rod 214 is used to apply pressure to the first moving seat 10 and the second moving seat 11 and overcome the force of the first linear actuator 212 and the second linear actuator 213, so that the first moving seat 10 and the second moving seat 11 are relatively far away. After the moving conductor 6 is placed between the first moving seat 10 and the second moving seat 11, the first electric push rod 214 is controlled to retract, and the first moving seat 10 and the second moving seat 11 are driven by the first linear actuator 212 and the second linear actuator 213 to move closer to each other and clamp the moving conductor 6.

[0071] It should also be noted that in other optional embodiments, the aforementioned first electric push rod 214 may not be provided. In this case, the first linear actuator 212 and the second linear actuator 213 may be common actuators such as pneumatic rods or electric push rods, and the first clamping seat 210 and the second clamping seat 211 may be driven to move in the third direction or in the opposite direction thereof by the first linear actuator 212 and the second linear actuator 213, respectively, so as to drive the first clamping seat 210 and the second clamping seat 211 to move closer to or farther from each other, thereby achieving the clamping and positioning of the moving conductor 6.

[0072] Combination Figure 1 , Figure 2 and Figure 4As shown, the first driving assembly 3 in this embodiment includes a first moving seat 10, a first clamping mechanism 30 and a first driving mechanism 31. The first moving seat 10 is slidably arranged on the workbench 1 along the first direction, the first clamping mechanism 30 is used to clamp and position the moving contact 7, the first clamping mechanism 30 is openably arranged on the first moving seat 10 along the third direction, and the first driving mechanism 31 is connected to the first moving seat 10 and is used to drive the first moving seat 10 to slide back and forth along the first direction. The first driving mechanism 31 in this embodiment is an electric push rod fixedly arranged on the workbench 1, and its output end is fixedly connected to the first moving seat 10. The structure of the first clamping mechanism 30 in this embodiment is similar to the aforementioned clamping mechanism 21. Specifically, the first clamping mechanism 30 includes a first clamping seat 300, a second clamping seat 301, two groups of first slide cylinders 302 and a group of second electric push rods 303. Among them, the two groups of first slide cylinders 302 are connected to the first clamping seat 300 and the second clamping seat 301 respectively, and the second electric push rod 303 is arranged between the first clamping seat 300 and the second clamping seat 301. When working, the second electric push rod 303 first applies a force to the first clamping seat 300 and the second clamping seat 301 to make the two move away from each other, and then the manipulator grabs the moving contact 7 and places the moving contact 7 between the first clamping seat 300 and the second clamping seat 301. Afterwards, the second electric push rod 303 is controlled to retract, and the first clamping seat 300 and the second clamping seat 301 are moved closer to each other under the action of the first slide cylinder 302 and the moving contact 7 is clamped and positioned. Then, the first moving seat 10 can be driven by the first driving mechanism 31 to drive the moving contact 7 to move along the first direction, so that the moving contact 7 can extend into the interior of the moving conductor 6.

[0073] It is easy to understand that in other optional embodiments, the first driving mechanism 31 may also include a driving motor and a transmission mechanism. The transmission mechanism may be a common rack and pinion transmission mechanism or a belt transmission mechanism. The driving motor drives the rack or transmission belt to move, and the first movable seat 10 is fixed on the above-mentioned rack or transmission belt. The first movable seat 10 can move back and forth along the first direction under the drive of the first driving mechanism 31.

[0074] Further, combined with Figure 1 , Figure 2 and Figure 5As shown, the automated assembly equipment provided in this embodiment also includes a first calibration component 35, and the first calibration component 35 includes an opening and closing mechanism and a third linear drive 350. Among them, the opening and closing mechanism includes a first movable block 351 and a second movable block 352 that can open and close relative to each other along the second direction, and the first movable block 351 and the second movable block 352 are both provided with a first calibration shaft 353 adapted to the pin hole of the moving contact 7, and the third linear drive 350 is connected to the opening and closing mechanism and is used to drive the opening and closing mechanism to reciprocate along the third direction. The moving contact 7 is provided at its end with an opening extending along its axial direction and an opening extending along its radial direction. For the convenience of description, the opening on the moving contact 7 extending along its radial direction is referred to as the first connecting pin hole 70, and the opening extending along its axial direction is referred to as the jack 71. Accordingly, in combination with Figure 6 and Fig.10 As shown, pin holes for connection are provided at both ends of the insulating pull rod 8. For the convenience of description, the pin hole provided at one end of the insulating pull rod 8 close to the moving contact 7 is called the second connection pin hole 80, and the pin hole provided at the other end is called the third connection pin hole 81. During assembly, one end of the insulating pull rod 8 is inserted into the jack 71 of the moving contact 7, and the second connection pin hole 80 on the insulating pull rod 8 is aligned with the first connection pin hole 70 on the moving contact 7, and then the connecting pin shaft 9 is used to pass through the first connection pin hole 70 and the second connection pin hole 80 for connection. The third connection pin hole 81 provided at the other end of the insulating pull rod 8 is used to connect with the driving structure, so that the driving structure can drive the insulating pull rod 8 to move and drive the moving contact 7 to move relative to the static contact to realize the circuit on and off.

[0075] In order to improve the accuracy of assembly, the first calibration component 35 is used to calibrate the angle accuracy of the moving contact 7 along the circumferential direction in this embodiment. Specifically, before the moving contact 7 is grasped and placed by the manipulator, the opening and closing mechanism is first driven by the third linear driver 350 to move in the opposite direction along the third direction, so that the opening and closing mechanism moves to a position where the moving contact 7 can be avoided. After the moving contact 7 is placed on the first clamping mechanism 30, the opening and closing mechanism is driven by the third linear driver 350 to move to a set position along the third direction. The set position means that, assuming that the placement position of the moving contact 7 is accurate, when the opening and closing mechanism is located at the set position, the first calibration axis 353 can be aligned with the first connecting pin hole 70 on the moving contact 7. A pneumatic clamp can be used as the opening and closing mechanism, and the first moving block 351 and the second moving block 352 can be controlled to approach or move away from each other by inflation and exhaust, so that the first calibration axis 353 can be matched with the first connecting pin hole 70 on the moving contact 7 to determine whether the angle of the moving contact 7 along the circumferential direction is accurate.

[0076] Accordingly, combined Figure 1 , Figure 2 , Fig. 9 and Fig.10As shown, the second driving assembly 4 in this embodiment includes a third moving seat 12, a second clamping mechanism 40 and a fifth driving mechanism 41. At the same time, the automated assembly equipment also includes a second calibration assembly arranged on the side where the second driving assembly 4 is located. Specifically, the third moving seat 12 is slidably arranged on the workbench 1 along the first direction, the second clamping mechanism 40 is openably arranged on the third moving seat 12 along the third direction, the second clamping mechanism 40 is used to clamp and position the insulating pull rod 8, and the fifth driving mechanism 41 is connected to the third moving seat 12 and is used to drive the third moving seat 12 to slide back and forth along the first direction. During operation, the insulating rod 8 can be grasped by the manipulator and placed in the second clamping mechanism 40. Specifically, the second clamping mechanism 40 includes a fifth linear actuator 400, a first clamping block 401 and a second clamping block 402. The fifth linear actuator 400 can drive the first clamping block 401 and the second clamping block 402 to move away from each other, and the manipulator can extend one end of the insulating rod 8 between the first clamping block 401 and the second clamping block 402, and then the insulating rod 8 is clamped and positioned by the first clamping block 401 and the second clamping block 402. Then, the third moving seat 12 is driven by the fifth driving mechanism 41, and the second clamping mechanism 40 and the insulating rod 8 are driven to move in the opposite direction of the first direction until the end of the insulating rod 8 is docked with the moving contact 7.

[0077] The fifth linear actuator 400 in this embodiment is fixedly arranged on the third moving seat 12, the first clamping block 401 is fixedly connected to one side of the fifth linear actuator 400 and can move along the third direction under the drive of the fifth linear actuator 400, and the second clamping block 402 is fixedly connected to the other side of the fifth linear actuator 400 and can move in the opposite direction along the third direction under the drive of the fifth linear actuator 400. The fifth linear actuator 400 in this embodiment is a bidirectional electric push rod, and the first clamping block 401 and the second clamping block 402 can be driven to move away from or close to each other by the fifth linear actuator 400. It is easy to understand that in some optional embodiments, the first clamping block 401 and the second clamping block 402 can be driven to move close to each other by the fifth linear actuator 400 to clamp and position the insulating pull rod 8. In this embodiment, a tension spring 43 is arranged between the first clamping block 401 and the second clamping block 402, and the two ends of the tension spring 43 are respectively fixedly connected to the first clamping block 401 and the second clamping block 402 and press the two to make the two have a tendency to move close to each other. When the first clamping block 401 and the second clamping block 402 need to be moved away from each other so as to facilitate the insertion of the insulating rod 8, the fifth linear actuator 400 applies a force to the first clamping block 401 and the second clamping block 402 to overcome the force of the tension spring 43. When the first clamping block 401 and the second clamping block 402 need to be moved closer to each other to clamp and position the insulating rod 8, the fifth linear actuator 400 is controlled to retract, and the first clamping block 401 and the second clamping block 402 move closer to each other under the action of the tension spring 43 and clamp and position the insulating rod 8.

[0078] The fifth driving mechanism 41 in this embodiment is a slide cylinder. It is easy to understand that in other optional embodiments, the fifth driving mechanism 41 may also include a driving motor and a transmission mechanism. The transmission mechanism may be a common rack and pinion transmission mechanism or a belt transmission mechanism. The driving motor drives the rack or transmission belt to move, and the third movable seat 12 is fixed on the above-mentioned rack or transmission belt. The third movable seat 12 can move back and forth along the first direction under the drive of the fifth driving mechanism 41.

[0079] In order to improve the accuracy of assembly, the angle accuracy of the movable insulating rod 8 along the circumferential direction is calibrated by the second calibration component in this embodiment. Specifically, the second calibration component includes two second calibration shafts 42, which are respectively arranged on the first clamping block 401 and the second clamping block 402, and the second calibration shafts 42 are adapted to the end hole structure of the insulating rod 8 (the aforementioned third connecting pin hole 81). By setting the second calibration shaft 42, on the one hand, it can be judged whether the insulating rod 8 is placed in place, and the alignment accuracy of the second connecting pin hole 80 on the insulating rod 8 and the first connecting pin hole 70 on the movable contact 7 in the subsequent assembly steps can be improved.

[0080] In addition, combined Figure 7 As shown, there is a docking hole 60 in the moving conductor 6 for the end of the moving contact 7 to pass through. In the related art, the following problems still exist in the process of installing the moving contact 7 into the moving conductor 6 by manual assembly operation: since the part of the moving contact 7 passing through the docking hole 60 is designed to fit with the inner wall of the docking hole 60, it is difficult to ensure that the moving contact 7 completely translates along its axis during actual operation, which will inevitably cause the end of the moving contact 7 to collide with the edge of the docking hole 60, thereby causing internal damage to the moving conductor 6 (the moving contact 7 is generally made of metal, and the part of the moving conductor 6 where the docking hole 60 is located is generally polytetrafluoroethylene).

[0081] In order to solve the above technical problems, Figure 1 , Figure 2 and Figure 8As shown, the first drive assembly 3 in this embodiment further includes a second drive mechanism 32, a third drive mechanism 33 and a first guide rod 34. The second drive mechanism 32 is arranged on the first moving seat 10 and is used to push the contact 7 along the first direction. The third drive mechanism 33 is arranged on the other side of the positioning assembly 2 relative to the second drive mechanism 32 along the first direction. The first guide rod 34 is connected to the third drive mechanism 33 and can be driven by the third drive mechanism 33 to move in the reverse direction of the first direction to dock with the moving contact 7. The first guide rod 34 in this embodiment is provided with a first protrusion 340 for plugging with the end hole structure of the moving contact 7. The docking refers to the first protrusion 340 on the first guide rod 34 extending into the jack 71 of the moving contact 7. During assembly, the first guide rod 34 is driven by the third drive mechanism 33 to move in the reverse direction of the first direction until the end of the first guide rod 34 passes through the moving conductor 6 and docks with the moving contact 7. The second driving mechanism 32 then drives the moving contact 7 to push the first guide rod 34 along the first direction and move along the first direction until the moving contact 7 passes through the docking hole 60 in the moving conductor 6 and extends into the moving conductor 6 .

[0082] In this embodiment, the first guide rod 34 is also made of polytetrafluoroethylene, and the end of the first guide rod 34 will not damage the movable conductor 6 even if it bumps when passing through the docking hole 60 in the movable conductor 6. The guidance of the first guide rod 34 can prevent the end of the movable contact 7 from bumping against the edge of the docking hole 60 on the movable conductor 6.

[0083] Furthermore, since it is necessary to extend the first guide rod 34 and the insulating pull rod 8 into the moving conductor 6 along the same side of the moving conductor 6, the automated assembly equipment provided in this embodiment further includes a second movable seat 11 slidably disposed on the workbench 1 and a fourth drive mechanism 16 connected to the second movable seat 11, and the fourth drive mechanism 16 is used to drive the second movable seat 11 to slide back and forth along the third direction. The third drive mechanism 33 and the second drive assembly 4 are arranged at intervals along the third direction and both are disposed on the second movable seat 11. By arranging the second movable seat 11 and the fourth drive mechanism 16, the positions of the second drive assembly 4 and the third drive mechanism 33 along the third direction can be switched, and then the insulating pull rod 8 or the first guide rod 34 can be aligned with the moving conductor 6 in the corresponding assembly step.

[0084] The second driving mechanism 32 in this embodiment is an electric cylinder, which can achieve precise position control and precise thrust control. The third driving mechanism 33 in this embodiment is a slide cylinder, and the fourth driving mechanism 16 is an electric push rod.

[0085] Combination Figure 1 , Fig.11 and Fig.12As shown, the third driving assembly 5 in this embodiment includes a fourth moving seat 13, a sixth linear driver 50 and a seventh linear driver 51. Among them, the fourth moving seat 13 is slidably arranged on the workbench 1 along the third direction, the sixth linear driver 50 is connected to the fourth moving seat 13 and is used to drive the fourth moving seat 13 to slide back and forth along the third direction, and the seventh linear driver 51 is fixedly arranged on the fourth moving seat 13 and is used to drive the connecting pin 9 to move along the second direction. The sixth linear driver 50 and the seventh linear driver 51 in this embodiment are both electric push rods. In this embodiment, a positioning groove (not shown in the figure) for positioning the connecting pin 9 is formed at the output end of the seventh linear driver 51, and the connecting pin 9 can be grasped by a manipulator and placed in the above-mentioned positioning groove. The sixth linear driver 50 and the seventh linear driver 51 in this embodiment are both electric push rods.

[0086] Furthermore, the third driving assembly 5 in this embodiment further includes a fifth moving seat 14, a sixth driving mechanism 52, a sixth moving seat 15, an eighth linear actuator 53, a ninth linear actuator 54 and a second guide rod 55. Similar to the aforementioned arrangement of the first guide rod 34, in this embodiment, the second guide rod 55 is arranged to dock with the connecting pin 9 to prevent the connecting pin 9 from bumping and damaging the edge of the second connecting pin hole 80 on the insulating pull rod 8.

[0087] Specifically, the fifth moving seat 14 in this embodiment is slidably disposed on the workbench 1, the sixth driving mechanism 52 is connected to the fifth moving seat 14 and is used to drive the fifth moving seat 14 to slide back and forth along the first direction, the sixth moving seat 15 is slidably disposed on the fifth moving seat 14, the eighth linear driver 53 is connected to the sixth moving seat 15 and is used to drive the sixth moving seat 15 to slide back and forth along the third direction, the ninth linear driver 54 is fixedly disposed on the sixth moving seat 15, and the second guide rod 55 is connected to the ninth linear driver 54 and can be driven by the ninth linear driver 54 to move in the reverse direction along the second direction to dock with the connecting pin 9. Among them, the second guide rod 55 is provided with a second protrusion 550 for plugging with the end hole structure of the connecting pin 9.

[0088] like Figure 7 As shown, the moving conductor 6 is provided with an assembly hole 61, and the assembly hole 61 can allow the connecting pin 9 and the second guide rod 55 to pass through the moving conductor 6 along the radial direction of the moving conductor 6. Before the moving conductor 6 is grasped by the manipulator and placed in the positioning assembly 2, the connecting pin 9 is first grasped by the manipulator and positioned at the output end of the seventh linear actuator 51. The fourth moving seat 13 is driven to move along the third direction by the sixth linear actuator 50, so that the seventh linear actuator 51 with the connecting pin 9 moves to a preset position, and the preset position refers to a position that enables the connecting pin 9 to align with the first connecting pin hole 70 and the second connecting pin hole 80 during assembly.

[0089] Furthermore, by driving the fifth moving seat 14 and the sixth moving seat 15 to move respectively through the sixth driving mechanism 52 and the eighth linear driver 53, the ninth linear driver 54 and the second guide rod 55 located on the sixth moving seat 15 can be driven to adjust their positions. Before the manipulator grabs the moving conductor 6 and places the moving conductor 6 in the positioning assembly 2, the positions of the ninth linear driver 54 and the second guide rod 55 are first adjusted to a position where the moving conductor 6 can be avoided. After that, the manipulator grabs the moving conductor 6 and places the moving conductor 6 in the positioning assembly 2, and then the sixth driving mechanism 52 and the eighth linear driver 53 drive the fifth moving seat 14 and the sixth moving seat 15 to move respectively, which can drive the ninth linear driver 54 and the second guide rod 55 located on the sixth moving seat 15 to adjust their positions, so that the second guide rod 55 moves to be coaxial with the connecting pin 9.

[0090] The sixth driving mechanism 52 in this embodiment is a slide cylinder, and the eighth linear drive 53 and the ninth linear drive 54 are both electric push rods.

[0091] The process of assembling circuit breaker contacts using the automated assembly equipment provided in this embodiment is described as follows:

[0092] First, the moving conductor 6, the moving contact 7, the insulating pull rod 8 and the connecting pin 9 are respectively grabbed by the manipulator and placed at the corresponding positions. The first guide rod 34 is driven by the third driving mechanism 33 to pass through the moving conductor 6 in the opposite direction of the first direction until the first protrusion 340 on the first guide rod 34 is inserted into the jack 71 of the moving conductor 6. Then, the first moving seat 10 is driven by the first driving mechanism 31 to move in the first direction, driving the moving contact 7 and the second driving mechanism 32 to move in the first direction. During this process, the moving contact 7 pushes the first guide rod 34 to move in the first direction. After the stroke of the first driving mechanism 31 reaches a certain value, the second driving mechanism 32 pushes the contact 7 so that the moving contact 7 pushes the first guide rod 34 to move in the first direction until the first connecting pin hole 70 on the moving contact 7 is aligned with the second guide rod 55.

[0093] Afterwards, the first guide rod 34 is driven to withdraw the moving conductor 6 in the first direction by the third driving mechanism 33, and the second movable seat 11 is driven to move in the third direction by the fourth driving mechanism 16, so that the positions of the first guide rod 34 and the insulating rod 8 can be switched, so that the insulating rod 8 is aligned with the moving conductor 6. Then, the third movable seat 12 and the insulating rod 8 located on the third movable seat 12 are driven to move in the opposite direction of the first direction by the fifth driving mechanism 41, until the insulating rod 8 moves to the point where its second connecting pin hole 80 is aligned with the first connecting pin hole 70.

[0094] Then, the ninth linear drive 54 drives the second guide rod 55 to move in the opposite direction along the second direction, so that the second guide rod 55 docks with the connecting pin 9, and finally the seventh linear drive 51 drives the connecting pin 9 to move in the second direction. During this process, the connecting pin 9 pushes on the second guide rod 55 until the end of the connecting pin 9 passes through the first connecting pin hole 70 and the second connecting pin hole 80 along the second direction.

[0095] Afterwards, the nut is grasped by a robot and screwed onto the end of the connecting pin 9 to realize the assembly of the moving contact 7 and the insulating pull rod 8.

[0096] It should be noted that the manipulator described in this embodiment is an existing device, and its working principle will not be described in detail. In addition, the moving distance and position of each component can also be determined by common detection elements such as displacement sensors and position detection sensors to ensure that the first connecting pin hole 70, the second connecting pin hole 80 and the connecting pin shaft 9 are aligned. The setting and use of the above-mentioned detection elements belong to the technology well known in the art and will not be described in detail here.

[0097] The above are only specific embodiments of the present application, but the protection scope of the present application is not limited thereto. Those skilled in the art should understand that the present application includes but is not limited to the contents described in the drawings and the above specific embodiments. Any modification that does not deviate from the functional and structural principles of the present application will be included in the scope of the claims.
