Description

Technical Field

[0001] This invention relates to the field of circuit breaker technology, specifically to a primary and secondary integrated circuit breaker and its processing equipment. Background Technology

[0002] A primary and secondary integrated circuit breaker is an intelligent switching device that integrates a primary conductive circuit and a secondary control unit. One of its core manufacturing processes is to use injection molding to seal an insert (such as a copper conductive insert) inside the insulating pole of the circuit breaker to form a conductive path. Before injection molding, the insert needs to be placed in a designated position inside the mold before the mold is closed for injection molding. After injection molding, the insert and the insulating pole form an integrated sealed structure.

[0003] Currently, the operation of placing the aforementioned inserts into the mold is usually done manually. That is, the operator uses hand tools or directly grasps the insert by hand, puts the insert through the predetermined opening of the mold into the cavity, and judges whether the insert has reached the predetermined position by visual inspection or experience after placement. In order to improve the positioning accuracy of the insert in the mold, some molds are equipped with auxiliary structures such as positioning pins or limiting grooves to help the operator position the insert.

[0004] However, the above-mentioned manual operation method still has the following drawbacks: since the injection mold is usually preheated to a high temperature before injection, the mold temperature can reach more than 100 degrees Celsius. When loading materials, the operator needs to come into close contact with the mold opening area, which poses a risk of burns. In addition, the degree of automation is low. Summary of the Invention

[0005] The purpose of this invention is to provide a primary and secondary integrated circuit breaker and its processing equipment to solve the problems in the prior art where personnel need to come into close contact with the mold opening area during material loading, which poses a risk of burns, and the degree of automation is low.

[0006] The technical problem to be solved by the present invention can be achieved by the following technical solution: a primary and secondary integrated circuit breaker, comprising a circuit breaker body and an insert embedded in the circuit breaker body, the insert having an outwardly extending conductive rod, the insert being fixed inside the insulating pole of the circuit breaker body by injection molding process, and the conductive rod extending outside the insulating pole.

[0007] A processing device for manufacturing the primary and secondary fusion circuit breaker includes a conveyor table, a gantry frame is fixedly installed on one side of the top of the conveyor table, two sets of lifting plates for supporting inserts are hinged to the front side of the gantry frame, the ends of the lifting plates are bent areas, and limit posts are installed on the top wall of the lifting plates near the bent areas.

[0008] Preferably, a hydraulic cylinder is rotatably mounted on the top wall of the conveyor platform, and the top of the hydraulic cylinder is rotatably connected to the bottom of the lifting plate.

[0009] Preferably, a cylinder is provided in the middle of the gantry frame, and a push plate adapted to the outer wall of the insert is fixedly installed at the extended end of the cylinder.

[0010] Preferably, a horizontal plate for limiting and fixing the cylinder is provided above the gantry frame.

[0011] Preferably, two sets of guide rods are slidably provided on the inner wall of the conveyor table, and the bottom of the guide rods extends to the bottom of the conveyor table and is fixedly installed with friction blocks.

[0012] Preferably, the top of the guide rod extends above the conveyor table and is rotatably mounted with rollers that abut against the lifting plate.

[0013] Preferably, a limiting ring is fixedly installed on the outer wall above the guide rod, and a guide sleeve coaxially arranged with the guide rod is also installed on the conveying platform. A thrust spring is sleeved on the outer wall of the guide rod located between the limiting ring and the guide sleeve.

[0014] Preferably, a positioning ring is provided on the outer side wall of the lifting plate, and a rotating shaft is provided on the outer wall of the lifting plate to limit the positioning ring. An electric push rod is fixedly installed at the bottom of the positioning ring, and a snap-fit ​​sleeve is installed at the extended end of the electric push rod. An adjusting rod is installed between the two sets of snap-fit ​​sleeves.

[0015] Preferably, a servo motor for driving the rotation of the shaft is embedded in the inner wall of a set of lifting plates.

[0016] Compared with the prior art, the beneficial effects of this application are as follows: 1. This invention constructs a fully automated operation process from insert loading, lifting and conveying, transfer and docking to pushing into the mold by setting two sets of lifting plates hinged to the gantry, hydraulic cylinders driving the lifting plates to rotate, and cylinder push plates for pushing inserts. This replaces the manual operation of putting inserts into high-temperature molds, which not only eliminates safety hazards, but also improves production efficiency and product consistency.

[0017] 2. This invention utilizes the downward pressing action of the lifting plate at its lowest position. Through the coordinated action of rollers, guide rods, thrust springs, and friction blocks, the conveyor table is automatically limited and stabilized during the two key processes of feeding and pushing, ensuring the smoothness of cylinder movement and the precision of insert placement. During the walking and resetting phases, the limit is automatically released without affecting the movement of the equipment. The entire mechanism requires no additional power source and achieves automatic switching between limit setting and limit release entirely through the equipment's own actions.

[0018] 3. This invention adds a swingable adjustment rod driven by a servo motor, which provides an initial limit when the insert is loaded. During the rotation of the support plate, the rod swings adaptively with the posture of the insert. After the insert is transferred to the mold hook, the servo motor drives the adjustment rod to deflect so that the bottom of the insert fits against the inner wall of the push plate. Then, an electric push rod moves the adjustment rod to the bottom of the insert to provide bottom support. Thus, posture correction and bottom support are completed before the insert is pushed. This solves the technical problem that the push plate cannot fully fit the outer wall of the insert and the insertion position deviation is caused by the offset of the center of gravity of the T-shaped insert, thus ensuring the insertion accuracy of the insert.

[0028] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0029] Example 1 In the production process of existing integrated primary and secondary circuit breakers, inserts (such as copper conductive inserts) need to be sealed inside the insulating poles of the circuit breaker through injection molding. Before injection molding, the inserts need to be placed in the designated positions of the mold. However, this operation is usually done manually, that is, the operator needs to manually put the inserts into the mold with high temperature. This not only poses safety hazards such as burns, but also has a low degree of automation, affecting production efficiency and product consistency.

[0030] like Figures 1 to 6 In this embodiment, a processing device for manufacturing a primary and secondary fusion circuit breaker is provided, including a conveyor table 4. A gantry frame 2 is fixedly installed on one side of the top of the conveyor table 4. Two sets of lifting plates 5 for supporting inserts are hinged to the front side of the gantry frame 2. The ends of the lifting plates 5 are bent areas, and limit posts 10 are installed on the top wall of the lifting plates 5 near the bent areas. A hydraulic cylinder 9 is rotatably installed on the top wall of the conveyor table 4, and the top of the hydraulic cylinder 9 is rotatably connected to the bottom of the lifting plate 5. A cylinder 7 is provided in the middle of the gantry frame 2. A push plate 8 adapted to the outer wall of the insert is fixedly installed at the extended end of the cylinder 7. A horizontal plate 6 is provided above the gantry frame 2 to limit and fix the cylinder 7.

[0031] like Figure 6 , Figure 7 , Figure 8 As shown, the working principle of this processing equipment is as follows: 1. The insert (copper conductive insert) constituting the primary and secondary integrated circuit breaker is precisely placed in the bending area between the two sets of lifting plates 5. That is, the conductive rod arranged horizontally inside the insert is located in the bending area and its end extends outside the bending area for later use with the mold hook. At this time, the extended end of the hydraulic cylinder 9 is in the shortest retracted state, and the lifting plate 5 is in the lowest position, which facilitates the insertion operation. 2. Control the extended end of the hydraulic cylinder 9 to be fully extended, i.e., the longest position. The hydraulic cylinder 9 pushes the two sets of lifting plates 5, which rotate upward synchronously with the hinge point of the gantry frame 2 as the fulcrum, pushing the insert upward to the predetermined height. After maintaining this state, the entire equipment along with the insert is transported to the designated position between the two sets of molds through the cooperation of the conveyor table 4 and the limiting fixture 1. 3. Control the extension end of the hydraulic cylinder 9 to retract to half its length, and the lifting plate 5 rotates downward with its hinge point with the gantry 2 as the fulcrum. As the lifting plate 5 moves downward, the bottom wall of the conductive rod arranged horizontally in the insert gradually descends until it contacts the top wall of the mold hook, thereby completing the smooth transfer of the insert from the lifting plate 5 to the mold hook. At this time, the insert and the push plate 8 correspond to each other. 4. As the insert is transferred to the mold hook, the hydraulic cylinder 9 continues to retract to the fully reset state, i.e., the shortest position, which drives the lifting plate 5 to reset synchronously. Fifth, control the cylinder 7 to extend, and push the insert that has been transferred to the mold hook to the predetermined position inside the mold in the horizontal direction. After the insert installation is completed, control the cylinder 7 to reset, control the hydraulic cylinder 9 to extend upward to the safe length, and move the equipment out between the two sets of molds through the limit fixture 1. Then control the extended end of the hydraulic cylinder 9 to retract to the fully reset state and enter the next working cycle.

[0032] It should be emphasized that the core improvement of this embodiment lies in: by setting up two sets of lifting plates 5 hinged to the gantry 2, hydraulic cylinders 9 that drive the lifting plates 5 to rotate, and cylinders 7 and push plates 8 for pushing inserts, a fully automated operation process is constructed from insert loading, lifting and conveying, transfer and docking to pushing into the mold, which replaces the manual operation of putting inserts into the high-temperature mold, thus eliminating safety hazards and improving production efficiency and product consistency.

[0033] It should be noted that the limiting post 10 is used to limit the lateral position of the insert during the lifting process of the lifting plate 5, so as to prevent the insert from shifting laterally during the lifting process; the limiting plate 11 is used to position the axial position of the insert.

[0034] It should be noted that the outer wall of the push plate 8 is adapted to the outer wall of the insert to ensure that the push plate 8 and the outer wall of the insert are closely fitted during the pushing process of the cylinder 7, so as to push the insert smoothly and accurately to the predetermined position inside the mold and avoid the insert being pushed off-center due to poor fit.

[0035] like Figures 1 to 2 In this embodiment, a horizontal plate 6 is provided above the gantry frame 2, and the cylinder 7 is fixedly installed on the horizontal plate 6. The horizontal plate 6 plays a role in limiting and fixing the cylinder 7, ensuring that the cylinder 7 maintains a stable working posture during repeated extension and retraction, thereby ensuring that the push plate 8 can accurately push the insert along the same trajectory each time.

[0036] In this embodiment, the insert has a T-shaped structure, and its horizontally arranged conductive rod area is used to abut and cooperate with the bent area of ​​the support plate 5.

[0037] Example 2 It is understandable that in Embodiment 1, insert feeding and cylinder 7 pushing are two key processes that directly affect the final mold entry accuracy of the insert. When the insert is fed, it will be impacted and collided when it is placed on the support plate 5. When it is pushed, the extension of cylinder 7 will generate a reaction force. Both of these conditions will cause the conveyor table 4 to shake. The shaking of the conveyor table 4 will not only affect the accuracy of the initial position of the insert, but also directly affect the smoothness of the movement when cylinder 7 pushes the push plate 8, causing the insert to deviate from the predetermined position, and thus affecting the positioning accuracy of the insert inside the circuit breaker after injection molding.

[0038] like Figures 1-2 , Figure 4 , Figure 6 To address the aforementioned issues, two sets of guide rods 19 are slidably mounted on the inner wall of the conveyor table 4. The bottom of the guide rods 19 extends below the conveyor table 4 and is fixedly fitted with friction blocks 20; the top of the guide rods 19 extends above the conveyor table 4 and is rotatably fitted with rollers 23 that abut against the lifting plate 5. A limit ring 21 is fixedly mounted on the outer wall above the guide rods 19. A guide sleeve 18, coaxially arranged with the guide rods 19, is also mounted on the conveyor table 4. A thrust spring 22 is sleeved on the outer wall of the guide rods 19 located between the limit ring 21 and the guide sleeve 18.

[0039] like Figure 6 , Figure 7 , Figure 8 As shown, the working principle is as follows: When the hydraulic cylinder 9 is in its shortest retracted state, the lifting plate 5 is in its lowest position. The bottom of the lifting plate 5 presses the roller 23 downward. The roller 23 compresses the thrust spring 22 through the guide rod 19, causing the friction block 20 to press downward until it is in close contact with the top wall of the limiting fixture 1. The conveyor table 4 is stopped and stabilized. The impact generated when the insert is inserted is absorbed by the friction block 20, ensuring the positioning of the insert by the limiting post 10 and the limiting plate 11. After the insert is loaded, the hydraulic cylinder 9 extends to its longest position, the lifting plate 5 moves away from the lowest position, the pressure on the roller 23 is released, the thrust spring 22 pushes the guide rod 19 to reset, the friction block 20 disengages from the top wall of the limiting fixture 1, the limit is released, and the equipment moves freely between the two sets of molds through the limiting fixture 1. As the hydraulic cylinder 9 extends from its longest position to half its length, and the equipment moves to the designated position and completes the transfer of the insert to the mold hook, the hydraulic cylinder 9 simultaneously retracts to its shortest position. The lifting plate 5 returns to its lowest position and squeezes the roller 23 again. The friction block 20 re-engages tightly with the top wall of the limiting fixture 1, and the conveyor table 4 returns to its limit and stops. Subsequently, the cylinder 7 extends to push the insert into the mold. Since the conveyor table 4 has been reliably limited, the cylinder 7 moves smoothly, and the insert is accurately pushed into the mold.

[0040] It should be emphasized that the core improvement of this embodiment is that: by utilizing the downward pressing action of the lifting plate 5 at its lowest position, the conveyor table 4 is automatically limited and stabilized during the two key processes of feeding and pushing through the linkage of roller 23, guide rod 19, thrust spring 22 and friction block 20, ensuring the smooth movement of cylinder 7 and the precision of insert placement; while automatically releasing the limit during the walking and resetting phases, without affecting the movement of the equipment, the entire mechanism does not require an additional power source, and fully utilizes the equipment's own actions to achieve automatic switching between limit and release.

[0041] It should be noted that the guide sleeve 18 provides precise axial guidance for the guide rod 19, ensuring that the friction block 20 accurately contacts the top wall of the limiting fixture 1.

[0042] It should be noted that the safety length in Embodiment 1 is set according to actual production. Its purpose is to control the lifting plate 5 to move upward a certain distance so that the thrust spring 22 pushes the limiting ring 21 upward, thereby preventing the bottom of the friction block 20 from contacting the limiting fixture 1, reducing the running friction, and extending the service life of the friction block 20.

[0043] In this embodiment, the roller 23 contacts the bottom of the lifting plate 5 through rolling friction, reducing the frictional resistance between the lifting plate 5 and the guide rod 19, and avoiding jamming or abnormal wear.

[0044] Example 3 It is understandable that in Embodiment 2, the insert has a T-shaped structure, with its horizontally arranged conductive rods placed in the bending area of ​​the two sets of lifting plates 5 as support, and its vertically arranged bottom extending downwards. During the process of the hydraulic cylinder 9 driving the lifting plate 5 to rotate from the lowest position to the longest position and then retract from the longest position to half position, the support angle of the lifting plate 5 continuously changes. Because the horizontally arranged area of ​​the insert is relatively heavy compared to the vertically arranged suspended area, it is difficult for the vertically arranged bottom of the insert to always remain in a vertically suspended state when the angle of the lifting plate 5 changes. This causes the push plate 8 to fail to fully fit the outer wall of the insert when it starts to push, and the insert may deviate from the predetermined position. After injection molding, the positional accuracy of the insert inside the circuit breaker cannot be guaranteed, resulting in quality defects such as uneven wall thickness in some areas, which affects the performance of the circuit breaker.

[0045] like Figure 3 , Figure 5 To address the aforementioned issues, a positioning ring 14 is provided on the outer side wall of the lifting plate 5. A rotating shaft 12 is provided on the outer wall of the lifting plate 5 to limit the positioning ring 14. An electric push rod 15 is fixedly installed at the bottom of the positioning ring 14. A snap-fit ​​sleeve 16 is installed at the extended end of the electric push rod 15. An adjusting rod 17 is installed between two sets of snap-fit ​​sleeves 16. A servo motor 13 for driving the rotating shaft 12 to rotate is embedded on the inner wall of one set of lifting plates 5.

[0046] like Figure 6 , Figure 7 , Figure 8 As shown, the working principle is as follows: During the initial loading of the insert, the horizontally positioned conductive rod is placed in the bending area of ​​the two sets of lifting plates 5, and the vertically extended conductive rod of the insert is aligned with the outer wall of the adjusting rod 17 to ensure accurate initial positioning. Subsequently, the hydraulic cylinder 9 extends to its longest position, the lifting plate 5 rotates upward, and the adjusting rod 17 rotates with the lifting plate 5. The vertically extended area of ​​the insert rotates due to the influence of the center of gravity, making the vertically extended area of ​​the insert approach a vertical state. When the hydraulic cylinder 9 extends halfway, the lifting plate 5 rotates downward, and the insert... The vertical overhanging area of ​​the insert approaches a vertical state again under its own weight. When the insert is just transferred to the mold hook, the cylinder 7 moves to the mold side, and the upper part of the push plate 8 fits against the outer wall of the horizontal setting area of ​​the insert. Then, the servo motor 13 is controlled to rotate, and the adjusting rod 17 moves to one side of the insert, so that the outer wall of the bottom vertical overhanging area of ​​the insert is completely fitted against the inner wall of the push plate 8. The servo motor 13 stops working, and after fitting, the electric push rod 15 is controlled to extend. The servo motor 13 is controlled to work again, and the adjusting rod 17 is moved to the bottom of the insert.

[0047] It should be emphasized that the core improvement of this embodiment lies in the addition of a swingable adjustment rod 17 driven by a servo motor 13, which provides an initial limit when the insert is loaded. During the rotation of the support plate 5, the rod swings adaptively with the posture of the insert. After the insert is transferred to the mold hook, the servo motor 13 drives the adjustment rod 17 to deflect so that the bottom of the insert fits against the inner wall of the push plate 8. Then, the electric push rod 15 drives the adjustment rod 17 to move to the bottom of the insert to provide bottom support. Thus, the posture correction and bottom support are completed before the insert is pushed, solving the technical problem that the push plate 8 cannot fully fit against the outer wall of the insert and the insertion position deviation is caused by the offset of the center of gravity of the T-shaped insert, and ensuring the insertion accuracy of the insert.

[0048] It should be noted that the positioning ring 14 is fitted onto the outer wall of the rotating shaft 12, and the rotating shaft 12 is fixedly installed on the outer wall of the lifting plate 5. The positioning ring 14 can rotate freely around the rotating shaft 12, thereby realizing the swing of the electric push rod 15 and the adjusting rod 17 around the rotating shaft 12. The snap-fit ​​sleeve 16 is fixedly installed on the extended end of the electric push rod 15, and the two ends of the adjusting rod 17 are respectively snapped into the two sets of snap-fit ​​sleeves 16, which facilitates the installation, disassembly and replacement of the adjusting rod 17.

[0049] It should be noted that the servo motor 13 is embedded in the inner wall of a set of lifting plates 5, and the output shaft of the servo motor 13 is connected to the rotating shaft 12 for transmission. Through the precise control of the servo motor 13, the angle of the rotating shaft 12 can be precisely adjusted, thereby ensuring that the adjusting rod 17 can accurately reach the predetermined position under different working conditions.

[0050] As can be seen from Embodiments 1, 2, and 3 of this invention, in this application, the hydraulic cylinder 9, air cylinder 7, electric push rod 15, and servo motor 13 are all controlled by a PLC controller (programmable logic controller) according to a preset timing program. Each actuator is connected to the PLC controller via a corresponding solenoid valve or driver. The above control method is a conventional technical means in the field of industrial automation, and those skilled in the art can implement it according to the working timing disclosed in the specification.

[0051] The conveyor 4 is a track-type walking mechanism or an AGV trolley. The conveyor 4 is fixedly installed above the limiting fixture 1, and the bottom of the conveyor 4 is provided with a ground rail 3. The conveyor 4 travels along the preset path on the limiting fixture 1 via the ground rail 3 to realize the transfer of equipment between workstations. The specific structure of the conveyor 4 and the limiting fixture 1 and their driving methods are well known in the field and will not be described in detail here.

[0052] Example 4 This application also provides a primary and secondary fusion circuit breaker manufactured using the processing equipment described in Embodiments 1 to 3 above; The integrated primary and secondary circuit breaker includes a circuit breaker body and an insert embedded within the circuit breaker body. The insert has an outwardly extending conductive rod. The insert is fixed inside the insulating pole of the circuit breaker body by injection molding, and the conductive rod extends outside the insulating pole.

[0053] The specific manufacturing process of the circuit breaker is as follows: the insert is placed in a predetermined position inside the injection mold cavity using the processing equipment described in Embodiments 1 to 3 above. Then the mold is closed and injection molding is performed. Molten insulating material fills the mold cavity and wraps the insert. After the material solidifies, the insert and the insulating pole form an integral solidified structure, thus obtaining the primary and secondary fusion circuit breaker described in this embodiment.

[0054] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed application.
