Description

Technical Field

[0001] This application relates to the field of disconnector manufacturing equipment technology, specifically to an assembly device for moving contacts. Background Technology

[0002] Moving contacts are the core movable components in electrical equipment (such as circuit breakers, contactors, and disconnectors) that enable circuit switching. Their assembly quality directly affects the conductivity, mechanical life, and operational safety of the equipment. Moving contacts generally include conductive components (arc-extinguishing contacts), arc-extinguishing components (small and large nozzles), insulating components (piston rods), and sealing components (arc-extinguishing chamber flanges, check valves, and arc-extinguishing contact seats). Currently, assembly is typically done manually. However, due to the large number of components in moving contacts, existing manual assembly methods are inefficient and struggle to guarantee product consistency. Utility Model Content

[0003] This application aims to address one of the technical problems in related technologies to a certain extent. To this end, this application provides an assembly device for moving contacts.

[0004] To achieve the above objectives, this application adopts the following technical solution: an assembly device for a moving contact, wherein the moving contact includes an arc-extinguishing chamber flange, a one-way valve, a piston rod, a moving arc contact, a moving arc contact seat, a small nozzle, an air chamber, and a large nozzle, and the assembly device includes:

[0005] The frame includes a base and a lifting seat that can be raised and lowered relative to the base;

[0006] A support platform, which is disposed on the base and is provided with a first support seat and a second support seat; and,

[0007] A tooling platform is provided on the lifting seat and configured to be able to translate relative to the support platform. The tooling platform is provided with a first screwing tool, a second screwing tool and a third screwing tool.

[0008] The first support base is used to place the arc-extinguishing chamber flange, one-way valve, piston rod and moving arc contact, the second support base is used to place the gas chamber, the first screwing tool is used to tighten the moving arc contact seat to the arc-extinguishing chamber flange, the second screwing tool is used to tighten the small nozzle to the moving arc contact seat to obtain the first intermediate structure, and the third screwing tool is used to tighten the large nozzle to the gas chamber to obtain the second intermediate structure.

[0009] The application of this application has the following beneficial effects: By setting up a support platform and a tooling platform that can be moved relative to each other, the first, second, and third tightening tooling can be conveniently controlled to move relative to the first and second support seats according to assembly requirements. When it is necessary to tighten the assembly of the moving arc contact seat and the arc-extinguishing chamber flange, the first tightening tooling is controlled to align with the first support seat; when it is necessary to tighten the assembly of the small nozzle and the moving arc contact seat, the second tightening tooling is controlled to align with the first support seat; and when it is necessary to tighten the assembly of the large nozzle and the air chamber, the third tightening tooling is controlled to align with the second support seat. A lifting seat that can be raised and lowered relative to the base can be set up, which can drive the tooling platform to move up and down relative to the support platform. This allows for convenient control of the distance between the tooling platform and the support platform. Adjusting the distance between them to a larger value facilitates the robotic arm's gripping of the moving contact components relative to the support platform and the tooling platform, avoiding interference problems. When a tightening operation is required, the tooling platform can be controlled to move closer to the support platform. This enables automated assembly of the moving contact, improving assembly efficiency and product consistency.

[0042] This embodiment provides an assembly device for moving contacts, such as... Figure 1 , Figure 2 , Figure 3 and Figure 8 As shown, the assembly equipment includes a frame 1, a support platform 2, and a tooling platform 3. The frame 1 includes a base 10 and a lifting seat 12 that can move up and down relative to the base 10. The support platform 2 is disposed on the base 10 and has a first support seat 20 and a second support seat 21. The tooling platform 3 is disposed on the lifting seat 12 and configured to translate relative to the support platform 2. The tooling platform 3 has a first tightening tool 4, a second tightening tool 5, and a third tightening tool 6. In this embodiment, the first support seat 20 is used to place the arc-extinguishing chamber flange 90, the one-way valve 91, the piston rod 92, and the moving arc contact 93. The second support seat 21 is used to place the gas chamber 96. In this embodiment, the first tightening tool 4 is used to tighten the moving arc contact seat 94 to the arc-extinguishing chamber flange 90, the second tightening tool 5 is used to tighten the small nozzle 95 to the moving arc contact seat 94 to obtain a first intermediate structure, and the third tightening tool 6 is used to tighten the large nozzle 97 to the gas chamber 96 to obtain a second intermediate structure.

[0043] By setting up mutually movable support platforms 2 and tooling platforms 3, the first tightening tool 4, the second tightening tool 5, and the third tightening tool 6 can be conveniently controlled to translate relative to the first support base 20 and the second support base 21 according to assembly requirements. When it is necessary to tighten the assembly of the moving arc contact seat 94 and the arc extinguishing chamber flange 90, the first tightening tool 4 is controlled to align with the first support base 20; when it is necessary to tighten the assembly of the small nozzle 95 and the moving arc contact seat 94, the second tightening tool 5 is controlled to align with the first support base 20; and when it is necessary to tighten the assembly of the large nozzle 97 and the air chamber 96, the third tightening tool 6 is controlled to align with the second support base 21. A lifting seat 12 that can be raised and lowered relative to the base 10 is provided. The lifting seat 12 can drive the tooling platform 3 to move up and down relative to the support platform 2, thereby conveniently controlling the distance between the tooling platform 3 and the support platform 2. Adjusting the distance between the two to a larger value makes it easier for the robotic arm 14 to grasp the components of the moving contact 9 relative to the support platform 2 and the tooling platform 3, avoiding interference problems. When a screwing operation is required, the tooling platform 3 can be moved closer to the support platform 2. This enables automated assembly of the moving contact 9, improving assembly efficiency and product consistency.

[0044] It should be noted that, in combination Figure 2 , Figure 3 and Figure 8 As shown, the moving contact 9 in this embodiment includes an arc-extinguishing chamber flange 90, a one-way valve 91, a piston rod 92, a moving arc contact 93, a moving arc contact seat 94, a small nozzle 95, an air chamber 96, and a large nozzle 97.

[0045] It is easy to understand that, Figure 1 The robotic arm 14 shown, used for grasping, placing, and moving the various components of the moving contact 9, can be included in the assembly equipment provided in this embodiment, or it can be used as a separate device in conjunction with the assembly equipment provided in this embodiment. This robotic arm 14 is a prior art product, and its working principle will not be described in detail here.

[0046] like Figure 1 and Figure 2 As shown, the frame 1 in this embodiment includes a base 10, a support frame 11 fixedly mounted on the base 10, and a lifting seat 12 mounted on the support frame 11. The lifting seat 12 is slidably mounted on the support frame 11 via a slide rail structure. In this embodiment, a lifting drive unit 13 for driving the lifting seat 12 to move up and down relative to the base 10 is also provided on the support frame 11. Specifically, the lifting drive unit 13 is an electric push rod.

[0047] In addition, to achieve relative sliding between the support platform 2 and the tooling platform 3, the assembly equipment provided in this embodiment further includes a first drive unit 32 disposed on the lifting seat 12 and a second drive unit 22 disposed on the base 10. The first drive unit 32 is connected to the tooling platform 3 and is used to drive the tooling platform 3 to move horizontally, while the second drive unit 22 is connected to the support platform 2 and is used to drive the support platform 2 to move horizontally. Of course, only the first drive unit 32 or only the second drive unit 22 may be provided. In this embodiment, the first drive unit 32 is an electric slide table, and the second drive unit 22 is an electric push rod.

[0048] Combination Figure 3 and Figure 4As shown, the first screwing fixture 4 in this embodiment includes a first sleeve 40, a first detection unit 41, and a first linear actuator 42. The first sleeve 40 has a receiving cavity for accommodating the moving arc contact seat 94, and is provided with a first through hole 400 and a second through hole 401. The first detection unit 41 is disposed outside the first sleeve 40 and detects the position information of the moving arc contact seat 94 through the first through hole 400. The first linear actuator 42 is disposed outside the first sleeve 40, and its output shaft is configured to extend through the second through hole 401 into the receiving cavity and connect with the moving arc contact seat 94. With this structural design, when the robotic arm 14 grasps the moving arc contact seat 94 and places it into the receiving cavity of the first sleeve 40, the position information of the moving arc contact seat 94 can be detected by the first detection unit 41. The positional information mentioned here refers to two aspects: firstly, whether the moving arc contact seat 94 is inserted into the first sleeve 40; and secondly, whether the pin hole on the moving arc contact seat 94 is aligned with the second through hole 401. In this embodiment, the first detection unit 41 is an infrared reflective sensor that emits infrared light and determines the distance to the target object by detecting the time difference between the emitted and received reflected infrared light.

[0049] In this embodiment, the first sleeve 40 is configured to rotate under the action of external force. Specifically, the first screwing tool 4 in this embodiment also includes a first connecting rod 43 disposed on the first sleeve 40. The first screwing tool 4 can be rotated as a whole by driving the first connecting rod 43 with external force.

[0050] The specific working process of the first screwing fixture 4 is described as follows: After the robotic arm 14 grasps the moving arc contact seat 94 and places it into the receiving cavity of the first sleeve 40, the time difference between the emission and reception of infrared rays by the first detection unit 41 changes due to the obstruction of the moving arc contact seat 94, thus indicating that the moving arc contact seat 94 has been placed into the first sleeve 40. It should be noted that the pin hole on the moving arc contact seat 94 has two possible positions after it is placed into the first sleeve 40: one is that it is offset from the first detection unit 41 circumferentially (in most cases), and the other is that it is aligned with the first detection unit 41. It is easy to understand that the change in the time difference between the emission and reception of infrared rays by the first detection unit 41 is different in these two different situations. Therefore, if the pin hole of the moving arc contact seat 94 is aligned with the first detection unit 41 after the moving arc contact seat 94 is placed inside the first sleeve 40, the first tightening fixture 4 can be rotated by a set angle to align the pin hole of the moving arc contact seat 94 with the second through hole 401. The set angle refers to the circumferential interval angle between the first detection unit 41 and the first linear actuator 42. If the pin hole on the moving arc contact seat 94 fails to align with the first detection unit 41 after the moving arc contact seat 94 is placed inside the first sleeve 40, the first tightening fixture 4 needs to be rotated again until the time difference between the first detection unit 41 emitting and receiving infrared light changes again, indicating that the pin hole on the moving arc contact seat 94 is now aligned with the first detection unit 41. Then, the first tightening fixture 4 can be rotated by a set angle to align the pin hole of the moving arc contact seat 94 with the second through hole 401.

[0051] After the pin hole of the moving arc contact seat 94 is aligned with the second through hole 401, the first linear driver 42 operates so that its output shaft passes through the second through hole 401 and is inserted into the pin hole of the moving arc contact seat 94. In this way, the moving arc contact seat 94 can be rotated by the first screwing fixture 4.

[0052] Combination Figure 3 and Figure 5As shown, the second screwing fixture 5 in this embodiment includes a second sleeve 50, a second detection unit 51, and a second linear actuator 52. The second sleeve 50 has a receiving cavity for accommodating a small nozzle 95, and is provided with a first opening 500 and a second opening 501. The second detection unit 51 is disposed outside the second sleeve 50 and detects the position information of the small nozzle 95 through the first opening 500. The second linear actuator 52 is disposed outside the second sleeve 50, and its output shaft is configured to extend through the second opening 501 into the receiving cavity and connect with the small nozzle 95. In this embodiment, the second sleeve 50 is configured to rotate under external force. Similarly, the second screwing fixture 5 in this embodiment also includes a second connecting rod 53 disposed on the second sleeve 50. Driving the second connecting rod 53 with external force can drive the entire second screwing fixture 5 to rotate.

[0053] The second detection unit 51 in this embodiment is also an infrared reflective sensor. The working principle of the second screwing fixture 5 is the same as that of the first screwing fixture 4, and will not be described again here.

[0054] Combination Figure 3 and Figure 6 As shown, the third screwing fixture 6 in this embodiment includes a connecting frame 60 and a gripper 61 disposed on the connecting frame 60. The gripper 61 is used to clamp and fix the large nozzle 97. The connecting frame 60 is configured to rotate under the action of external force. Similarly, the third screwing fixture 6 in this embodiment also includes a third docking rod 62 disposed on the connecting frame 60. By driving the third docking rod 62 with external force, the third screwing fixture 6 can be rotated as a whole, thereby causing the large nozzle 97 held by the fixture to rotate.

[0055] Furthermore, such as Figure 1 and Figure 3 As shown, the assembly equipment provided in this embodiment also includes a turning power unit 7 disposed on the lifting seat 12. The turning power unit 7 is located above the tooling platform 3. The turning power unit 7 includes a power source 70 and a coupling joint 71 that can be driven to rotate by the power source 70. The coupling joint 71 is used to dock with the first turning tooling 4, the second turning tooling 5, and the third turning tooling 6 respectively. Specifically, the coupling joint 71 in this embodiment is hexagonal, and slots for mating with the coupling joint 71 are provided at the ends of the first docking rod 43, the second docking rod 53, and the third docking rod 62. When the coupling joint 71 is inserted into the slot, it can drive the corresponding first turning tooling 4, the second turning tooling 5, and the third turning tooling 6 to rotate.

[0056] The screwing power unit 7 in this embodiment also includes a third drive unit 72 disposed on the lifting base 12 and a mounting bracket 73 connected to the third drive unit 72. The power source 70 is disposed on the mounting bracket 73, and the third drive unit 72 is used to drive the power source 70 and the connector 71 to move up and down. Through the above structural design, the insertion and separation of the connector 71 relative to the first docking rod 43, the second docking rod 53 and the third docking rod 62 can be easily realized.

[0057] To prevent jamming during the tightening operation, this embodiment also includes a structural design for the tooling platform 3. Specifically, in conjunction with... Figure 3 and Figure 7 As shown, the tooling platform 3 in this embodiment includes a support frame 30 and three sets of elastic pressure components 31. Each elastic pressure component 31 includes a connecting column 310 disposed on the support frame 30, a connecting plate 311 slidably disposed on the connecting column 310, a limiting block 312 disposed on the connecting column 310, and an elastic element 313 disposed between the support frame 30 and the connecting plate 311. The elastic element 313 applies pressure to the connecting plate 311, causing it to tend to move away from the support frame 30. The first tightening tool 4, the second tightening tool 5, and the third tightening tool 6 are respectively connected to the connecting plate 311 in the three sets of elastic pressure components 31.

[0058] Taking the operation of tightening the moving arc contact seat 94 to the arc-extinguishing chamber flange 90 using the first tightening fixture 4 as an example, the working principle of the elastic pressure application component 31 in this embodiment is explained as follows: First, the lifting seat 12 drives the fixture platform 3 to move down as a whole, so that the moving arc contact seat 94 located in the first tightening fixture 4 abuts against the arc-extinguishing chamber flange 90 located on the first support seat 20. It should be noted here that in this embodiment, the first support seat 20 and the second support seat 21 are spaced apart. In this way, when the first tightening fixture 4 is aligned with the first support seat 20, the spacing between the third tightening fixture 6 and the first support seat 20 and the second support seat 21 is aligned, thereby avoiding interference when the fixture platform 3 moves down.

[0059] Subsequently, the tooling platform 3 continues to move downward via the lifting seat 12. The reaction force applied by the arc-extinguishing chamber flange 90 to the moving arc contact seat 94 can push the first tightening tool 4 and the connecting plate 311 to move upward in the opposite direction and compress the elastic element 313. Then, the first tightening tool 4 and the moving arc contact seat 94 are driven to rotate by the tightening power unit 7, so that the moving arc contact seat 94 is tightened onto the arc-extinguishing chamber flange 90. During the tightening process, the elastic element 313 can continuously apply downward pressure to the first tightening tool 4 and the moving arc contact seat 94 to ensure that the moving arc contact seat 94 can also move downward while rotating, avoiding jamming during the tightening operation.

[0060] To facilitate assembly, a connecting cylinder 314 is also provided in this embodiment. The upper end of the connecting cylinder 314 is fixedly installed to the connecting plate 311 via a shaft. The connecting cylinders 314 provided in the three sets of elastic pressure components 31 are respectively used to be fixedly connected to the first screwing tool 4, the second screwing tool 5 and the third screwing tool 6.

[0061] Combination Figure 1 and Figure 8 As shown, the assembly equipment provided in this embodiment also includes an assembly table 8 and an electric screwdriver 83. The assembly table 8 is used to place the first intermediate structure and the second intermediate structure, and the electric screwdriver 83 is used to tighten the arc-extinguishing chamber flange 90 in the first intermediate structure to the air chamber 96 in the second intermediate structure. The electric screwdriver 83 is an existing product, and its working principle will not be described in detail. A robotic arm 14 can be used to grasp the electric screwdriver 83 for operation.

[0062] Furthermore, the assembly equipment also includes a drive motor 80 mounted on the assembly table 8 and a positioning structure mounted on the output end of the drive motor 80. The positioning structure is used to position the first intermediate structure and the second intermediate structure circumferentially. With this structural design, the drive motor 80 can drive the first and second intermediate structures to rotate, facilitating the screw-tightening operation of the electric screwdriver 83. After tightening one screw, there is no need to change the position of the electric screwdriver 83; simply driving the first and second intermediate structures to rotate via the drive motor 80 will align the other hole with the screw.

[0063] like Figure 8 As shown, the positioning structure in this embodiment includes a positioning ring 81 and a spring plunger 82 disposed on the positioning ring 81. Specifically, a through hole is provided on the positioning ring 81, and the spring plunger 82 is fixedly disposed in the through hole, with the ball head of the spring plunger 82 extending out of the inner wall surface of the positioning ring 81. The spring plunger 82 is an existing product, and its working principle is existing technology, which will not be described in detail here. The robotic arm 14 grasps the second intermediate structure and places it inside the positioning ring 81. The large nozzle in the second intermediate structure extends into the positioning ring 81, and positioning is achieved by squeezing the ball head of the spring plunger 82.

[0064] Combination Figure 1 , Figure 2 , Figure 3 and Figure 8The working process of the assembly equipment is described as follows: First, the robotic arm 14 sequentially places the arc-extinguishing chamber flange 90, one-way valve 91, piston rod 92, and moving arc contact 93 of the moving contact 9 onto the first support base 20. It is easy to understand that positioning pins or other positioning components can be set on the first support base 20 according to the shape of components such as the arc-extinguishing chamber flange 90 and piston rod 92 to prevent the components from shaking. Then, the first screwing tool 4 screws the moving arc contact seat 94, which is placed inside the first sleeve 40, onto the arc-extinguishing chamber flange 90 in the aforementioned integrated structure. Next, the second screwing tool 5 screws the small nozzle, which is placed inside the second sleeve 50, onto the moving arc contact seat 94 in the aforementioned integrated structure, obtaining the first intermediate structure. Additionally, the robotic arm 14 places the air chamber 96 onto the second support base 21, and then the third screwing tool 6 screws the clamped large nozzle onto the air chamber 96, obtaining the second intermediate structure. Then, the robotic arm 14 picks up the first intermediate structure and the second intermediate structure and places them on the assembly table 8. The robotic arm 14 then picks up the electric screwdriver 83 and tightens the arc-extinguishing chamber flange 90 in the first intermediate structure and the gas chamber 96 in the second intermediate structure to complete the assembly.

[0065] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Those skilled in the art should understand that this application includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of this application will be included within the scope of the claims.
