Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automation equipment, in particular to a multi-station integrated machining equipment for battery connecting piece production. BACKGROUND

[0002] In the battery production and assembly process, the battery connecting piece is a key component for realizing the electrical connection between battery monomers, and its machining precision and efficiency directly affect the quality and production progress of the battery product. At present, the machining of the battery connecting piece usually needs to go through multiple processes such as drilling and bending. The existing machining mode usually uses single-station independent equipment to complete each process, that is, the drilling equipment is used to complete the punching operation first, and then the workpiece is manually transported to the bending equipment for bending machining.

[0003] This traditional machining mode has many disadvantages: first, the processes are dispersed, multiple equipment is needed, the equipment purchase cost and site occupation cost are high; second, the workpiece needs to be transported and positioned multiple times, which not only increases the labor intensity, but also easily leads to a decrease in machining precision due to positioning errors, affecting product consistency; third, the transportation interval between stations is long, the machining continuity is poor, the overall production efficiency is low, and it is difficult to meet the needs of large-scale batch production.

[0004] Therefore, it is of great significance to develop a multi-station equipment that can integrate drilling, bending and other processes to realize continuous and automated machining, in order to improve the machining efficiency and precision of the battery connecting piece and reduce production costs. SUMMARY

[0005] Therefore, the purpose of the present application is to provide a multi-station integrated machining equipment for battery connecting piece production to solve the problems of dispersed machining processes, low efficiency, poor precision and high labor cost in the prior art.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical scheme: A multi-station integrated machining equipment for battery connecting piece production, comprising a jig assembly, a conveying assembly, a drilling assembly, a rack assembly and a bending assembly; The rack assembly comprises an equipment rack, and the top end of the equipment rack is provided with a machine table to provide installation support for each functional assembly. The conveying assembly comprises a conveying belt, which is installed at the top end of the machine table and is used to realize the continuous conveying of the jig and the workpiece. The feeding end of the conveying belt is provided with a guide frame to facilitate the accurate introduction of the jig loaded with the battery connecting piece into the clamping mechanism. Limiting strips are provided on the top end of the conveying belt near the drilling assembly and the bending assembly to limit the positioning of the connecting piece and ensure the machining positioning precision. The drilling assembly includes a drilling frame, which is fixedly installed on the top of the machine platform near the feed end of the conveyor belt. A lifting seat is slidably installed on the front of the drilling frame. A lifting electric cylinder is installed on the top of the drilling frame. The telescopic end of the lifting electric cylinder is fixedly connected to the lifting seat. The lifting seat is driven to slide up and down along the drilling frame by the lifting electric cylinder. A drilling motor is installed on the top of the lifting seat. A drill bit is driven to the output end of the drilling motor. The drill bit is driven to rotate at high speed by the drilling motor, which, together with the lifting movement of the lifting seat, realizes the drilling operation. The bending assembly includes a bending frame, which is fixedly connected to the top of the machine base and located on the discharge side of the conveyor belt, enabling the workpiece after drilling to be quickly transferred to the bending station. The bottom end of the bending frame is equipped with a pressing cylinder and a bending cylinder. There are two bending cylinders, which are symmetrically distributed on both sides of the pressing cylinder. The extension and retraction ends of the bending cylinder and the pressing cylinder are respectively equipped with a bending plate and a pressing block. The pressing cylinder drives the pressing block to press the middle of the workpiece, and the bending cylinders on both sides drive the bending plate to achieve downward bending of the workpiece at the drilling position. The fixture assembly includes a fixture placed at the top of the conveyor belt to support the battery connector. The fixture only supports the middle part of the connector, so that the parts of the connector that need to be bent and drilled are exposed at both ends of the fixture, which facilitates subsequent drilling and bending processing. The system also includes a clamping mechanism comprising a first fixing plate and a second fixing plate, which are symmetrically distributed on the front and rear sides of the conveyor belt for precise positioning and fixing of the battery connector during the drilling process. The front of the first fixing plate is equipped with cylinders one and two, and the telescopic ends of cylinders one and two are respectively equipped with pressure blocks one and two, which are used to fix the middle of the battery connector. The back of the second fixing plate is equipped with cylinders three, four, and five, and the telescopic ends of cylinders three, four, and five are respectively equipped with clamping plate one, a support block, and clamping plate two. The surface of the support block has a support hole. When cylinder four is in the expanded state, the support hole is located directly below the drill bit. The support block supports the workpiece at the drilling position, preventing workpiece deformation during drilling, and the support hole provides clearance for the drill bit, preventing damage to the drill bit.

[0007] Compared with the prior art, the beneficial effects of the present invention are: 1. Integrated design: The drilling and bending components are integrated on the same frame. The continuous transfer of workpieces is achieved through the conveying component, realizing the integrated processing of drilling and bending processes. There is no need for manual transfer of workpieces, which shortens the processing cycle, improves production efficiency, and reduces equipment space occupation and purchase costs.

[0008] 2. Precise positioning and high machining accuracy: A dedicated clamping mechanism is set up, and multiple sets of cylinders drive the pressure block and clamping plate to achieve precise positioning and fixation of the workpiece. At the same time, the limit strips on both sides of the conveyor belt ensure the stability of the jig's conveying trajectory. During drilling, the support block is precisely aligned with the drill bit position to provide effective support for the workpiece, avoid machining deformation, and significantly improve machining accuracy and product consistency.

[0009] 3. High degree of automation: The workpiece is automatically transported by the conveyor belt, and the various actuators are driven by cylinders and electric cylinders to complete the positioning, drilling, bending and other actions. The manual intervention is minimal, which reduces the intensity of manual labor, reduces human operation error, and improves processing stability.

[0010] 4. Reasonable structure and strong versatility: The fixture only supports the middle part of the workpiece, leaving the machining parts at both ends of the workpiece exposed, which is convenient to adapt to the machining requirements of battery connectors of different specifications. By adjusting the cylinder stroke and fixture size, multiple varieties of machining can be achieved, which is highly versatile.

[0020] Please see Figures 1-5This invention provides a technical solution for a multi-station integrated processing equipment for battery connector production: A multi-station integrated processing equipment for the production of battery connectors includes a jig assembly, a conveying assembly, a drilling assembly, a frame assembly, and a bending assembly; The rack assembly includes an equipment rack 1, with a platform 3 mounted on the top of the equipment rack 1 to provide a support base for the installation of various functional components; The conveying assembly includes a conveyor belt 2, which is installed on the top of the machine base 3 to realize the continuous conveying of the fixture and the workpiece. The feed end of the conveyor belt 2 is provided with a guide frame 13 to facilitate the accurate introduction of the fixture loaded with the battery connector into the clamping mechanism 15. A limit strip 17 is provided on the top of the conveyor belt 2 near the drilling assembly and bending assembly. The limit strip 17 prevents the battery connector from shifting during the conveying process and ensures the processing positioning accuracy. The drilling assembly includes a drilling frame 11, which is fixedly installed on the top of the machine base 3 near the feed end of the conveyor belt 2. A lifting seat 10 is slidably installed on the front of the drilling frame 11. A lifting cylinder 9 is installed on the top of the drilling frame 11. The telescopic end of the lifting cylinder 9 is fixedly connected to the lifting seat 10. The lifting seat 10 is driven to slide up and down along the drilling frame 11 by the lifting cylinder 9. A drilling motor 8 is installed on the top of the lifting seat 10. The output end of the drilling motor 8 is connected to the drill bit 14. The drill bit 14 is driven to rotate at high speed by the drilling motor 8, which, together with the lifting movement of the lifting seat 10, realizes the drilling operation. The bending assembly includes a bending frame 6, which is fixedly connected to the top of the machine base 3 and located on the discharge side of the conveyor belt 2, so as to realize the rapid transfer of the workpiece after drilling to the bending station. The bottom end of the bending frame 6 is equipped with a pressing cylinder 7 and a bending cylinder 5. There are two bending cylinders 5, which are symmetrically distributed on both sides of the pressing cylinder 7. The extension and retraction ends of the bending cylinder 5 and the pressing cylinder 7 are respectively equipped with a bending plate 4 and a pressing block 16. The pressing cylinder 7 drives the pressing block 16 to press the middle of the workpiece, and the bending cylinders 5 on both sides drive the bending plate 4 to achieve downward bending of the workpiece at the drilling position. The fixture assembly includes a fixture 12, which is placed at the top of the conveyor belt 2 to support the battery connector. The fixture 12 only supports the middle part of the connector, so that the parts of the connector that need to be bent and drilled are exposed at both ends of the fixture 12, which facilitates subsequent drilling and bending processes. It also includes a clamping mechanism 15, which includes a first fixing plate 21 and a second fixing plate 23. The first fixing plate 21 and the second fixing plate 23 are symmetrically distributed on the front and rear sides of the conveyor belt 2, and are used to accurately position and fix the battery connector during the drilling process. The front of the first fixing plate 21 is equipped with a first cylinder 18 and a second cylinder 20. The telescopic ends of the first cylinder 18 and the second cylinder 20 are respectively equipped with a first pressure block 22 and a second pressure block 29, which are used to fix the middle part of the battery connector. The second fixing plate 23... The back of drill bit 14 is equipped with cylinders 25, 26, and 27. The telescopic ends of cylinders 25, 26, and 27 are respectively equipped with clamping plate 24, support block 19, and clamping plate 28. The surface of support block 19 is provided with support hole 30. When cylinder 26 is in the expanded state, support hole 30 is located directly below drill bit 14. The support block 19 supports the workpiece drilling position to avoid workpiece deformation during drilling. At the same time, support hole 30 provides clearance space for drill bit 14 to prevent damage to the drill bit.

[0021] Multiple infrared sensors are installed on the conveyor belt 2 to sense the position of the fixture 12. Each component will execute the operation command only after reaching the designated position. The fixture 12 is equipped with a centering scale, and the battery connector is placed at the top of the fixture 12 in a centered position.

[0022] The specific steps are as follows: 1. Workpiece loading: Place the battery connector to be processed on the top of the fixture 12. According to the processing requirements, expose the two ends of the fixture 12 at the positions where the battery connector needs to be bent and drilled. The fixture 12 only supports the middle part of the battery connector to ensure that the processing part is not obstructed.

[0023] 2. Conveying and positioning: The fixture 12 loaded with battery connectors is guided into the conveyor belt 2 through the guide frame 13. The conveyor belt 2 is started, driving the fixture 12 to be conveyed towards the drilling assembly. Under the limiting action of the limit bar 17, the fixture 12 is conveyed smoothly along the preset trajectory until the fixture 12 reaches the drilling position, at which point the conveyor belt 2 stops running.

[0024] 3. First drilling and fixing: Start cylinder 4 26. The telescopic end of cylinder 4 26 extends, driving the support block 19 to move directly below the position to be drilled at one end of the battery connector, so that the support hole 30 is aligned with the position to be drilled; then start cylinder 1 18 and cylinder 3 25. The telescopic end of cylinder 1 18 extends, driving the pressure block 1 22 towards the workpiece. The telescopic end of cylinder 3 25 extends, driving the clamping plate 1 24 towards the workpiece. The pressure block 1 22 and the clamping plate 1 24 cooperate to clamp and fix the middle part of the battery connector.

[0025] 4. First drilling: Start the drilling motor 8, which drives the drill bit 14 to rotate at high speed; at the same time, start the lifting cylinder 9, which extends and drives the lifting seat 10 to slide downward, thereby driving the drill bit 14 to move downward to drill the position of the battery connector; after drilling is completed, the extension end of the lifting cylinder 9 retracts and drives the drill bit 14 to return to its original position, and the drilling motor 8 stops running; the extension ends of cylinder 18 and cylinder 325 retract, driving the pressure block 22 and clamping plate 24 to return to their original positions, releasing the fixation of the workpiece.

[0026] 5. Second drilling and fixing: Start cylinder 20 and cylinder 5 27. The telescopic end of cylinder 20 extends and drives the pressure block 29 to move towards the workpiece. The telescopic end of cylinder 5 27 extends and drives the clamping plate 28 to move towards the workpiece. The pressure block 29 and the clamping plate 28 work together to clamp and fix the middle part of the battery connector. At this time, the other end of the battery connector is located above the support block 19. This can be achieved by adjusting the position of the fixture or the stroke of the support block.

[0027] 6. Second drilling: Repeat the drilling action in step 4, start the drilling motor 8 and lifting cylinder 9, drive the drill bit 14 to drill the other end of the battery connector; after drilling is completed, reset all parts and loosen the fixation on the workpiece.

[0028] 7. Bending Conveying: Conveyor 2 starts again, driving the drilled workpiece and fixture 12 towards the bending assembly until they reach the bending station, at which point conveyor 2 stops running.

[0029] 8. Bending process: Start the pressing cylinder 7. The telescopic end of the pressing cylinder 7 extends and drives the pressing block 16 to move downward, pressing and fixing the middle part of the battery connector. Then, start the two symmetrically distributed bending cylinders 5. The telescopic end of the bending cylinder 5 extends and drives the bending plate 4 to move upward. The bending plate 4 acts on the punched position of the battery connector, bending the punched position downward to the preset angle. After the bending is completed, the telescopic ends of the bending cylinder 5 and the pressing cylinder 7 retract, driving the bending plate 4 and the pressing block 16 to reset, releasing the fixation of the workpiece.

[0030] 9. Discharge: The conveyor belt 2 starts and transports the workpiece and fixture 12 that have completed the bending process to the discharge end of the equipment. The processed battery connector is removed from the fixture 12 by manual or automated equipment. The fixture 12 can be recycled and reused.

[0031] The above description is merely a preferred embodiment of the present invention and does not limit the scope of protection of the present invention. For those skilled in the art, the present invention can have various modifications and variations. Any changes, modifications, substitutions, integrations, and parameter alterations to these embodiments within the spirit and principles of the present invention, achieved through conventional substitutions or by achieving the same function without departing from the principles and spirit of the present invention, fall within the scope of protection of the present invention.
