Description

Technical Field

[0001] This utility model relates to the field of copper busbar rolling, and in particular to a copper busbar rolling machine. Background Technology

[0002] In fields such as power equipment, new energy vehicles, rail transit, and industrial electrical control, copper busbars, as core components for high-current conductive connections, are widely used in devices such as distribution cabinets, inverters, and battery modules. To meet different installation spaces and electrical connection requirements, copper busbars often need to undergo forming processes such as bending, folding, or rolling. Among these, the rolling process is mainly used to manufacture key components such as ring busbars, motor winding connection terminals, and grounding rings.

[0003] As disclosed in the utility model patent application CN222535965U, a mechanism for processing rolled copper busbars includes: a copper busbar with a through hole at one end; a worktable with an opening; a rolling disc with a positioning groove on its outer wall for inserting the copper busbar; a locking mechanism having a positioning shaft that extends and retracts into the positioning groove and then into the through hole; a drive assembly that drives the rolling disc to rotate, roll the copper busbar, and vertically extend and retract to complete demolding; an auxiliary rolling mechanism having rollers that roll the copper busbar toward the rolling disc, and an elastic structure that drives the rollers to adaptively adjust the distance between them and the rolling disc; a guide mechanism that guides the copper busbar toward the positioning groove; and limiting rollers that limit the copper busbar on both sides.

[0004] The positioning shaft of the above-mentioned device needs to be inserted into the through hole at the end of the copper busbar. However, the copper busbar may have slight offset during the guiding and transmission process. If there is no centering or floating compensation structure, the positioning shaft may not be able to be accurately inserted into the through hole, causing the equipment to alarm or be damaged. The elastic structure realizes the adaptive adjustment of the roller through the spring, but the spring force is not adjustable. Different thickness copper busbars (such as 3mm vs 10mm) require different roller pressures. The fixed spring may not be able to adapt, which may cause the thin copper busbar to be over-pressed and deformed, and the thick copper busbar to be under-pressed and slipped.

[0005] Therefore, it is necessary to provide a new copper busbar rolling machine to solve the above-mentioned technical problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a copper busbar rolling machine.

A drive assembly is installed below the worktable, and an auxiliary winding mechanism is installed on the top of the worktable, located on one side of the winding disc. A limit roller assembly is installed between the guide mechanism and the auxiliary winding mechanism. A positioning groove for inserting copper busbars is formed inward on the outer wall of the winding disc, and the locking mechanism is located above the positioning groove. The locking mechanism includes a telescopic drive, a positioning block, a universal ball, a limit hemisphere, and a rotating hemisphere. A connecting hemisphere and a positioning cone rod are connected. A telescopic driver is installed inside the reel. The output end of the telescopic driver is fixedly connected to the bottom of the positioning block. The top inner wall of the positioning block is fixedly connected to the outer wall of the universal ball.

The bottom inner wall of the rotating hemisphere is rotatably connected to the outer wall of the universal ball. The top of the connecting hemisphere is fixedly connected to the bottom of the positioning cone rod.

[0008] Preferably, the inside of the rolling disc is provided with a cavity for accommodating the locking mechanism, and the cavity is provided with an opening that communicates with the positioning groove and is adapted to the positioning shaft.

[0009] Preferably, the driving component drives the rotating reel to roll the copper busbar and move it vertically to complete the demolding. The driving component includes a motor that drives the rotating reel to rotate and a lifter that drives the rotating reel to move up and down.

[0010] Preferably, the copper busbar has a through hole at its end, and a guide mechanism is installed on the top of the workbench. The guide mechanism consists of two guide rollers that are spaced apart vertically and rotate actively, and at least two sets are arranged horizontally. The copper busbar is located between the two guide rollers that are spaced apart vertically.

[0011] Preferably, the auxiliary winding mechanism has rollers that roll the copper busbar toward the winding disc, and an elastic structure that drives the rollers to adaptively adjust the distance between them and the winding disc. The elastic structure includes a positioning plate mounted on the worktable, a movable plate spaced apart from the positioning plate and used to rotate the mounting rollers, and a spring between the positioning plate and the movable plate. One side of the positioning plate is fixedly connected to an electric push rod two, one end of the electric push rod two is fixedly connected to a mounting plate, and the bottom of the mounting plate is fixedly connected to the top of the worktable.

[0012] Preferably, the limiting roller assembly is installed between the guiding mechanism and the auxiliary winding mechanism and corresponds to the positioning groove to limit the copper busbar on both sides. The axial cross-section of the limiting roller is I-shaped. The limiting roller assembly includes a guide rail, a slider, a mounting base, an electric actuator, and the limiting roller. The top of the worktable is provided with a mounting groove. The top of the inner wall of the mounting groove is fixedly connected to the bottom of the guide rail. The top of the guide rail is slidably connected to the bottom of the slider. The top of the slider is fixedly connected to the bottom of the mounting base. The side of the mounting base away from the copper busbar is fixedly connected to the output end of the electric actuator. One end of the electric actuator is fixedly connected to one side of the worktable. The top of the mounting base is fixedly connected to the bottom of the limiting roller.

[0013] Compared with related technologies, the copper busbar rolling machine provided by this utility model has the following beneficial effects: Through the composite floating structure composed of a universal ball, a limiting hemisphere, a connecting hemisphere, and a rotating hemisphere, the positioning cone rod can be freely adjusted within ±1mm offset in the X-axis or Y-axis direction and ±5° angle. This can effectively compensate for the inconsistency of through hole position caused by position error and processing deviation during the copper busbar conveying process. The front end of the positioning cone rod has a tapered structure. When it approaches the through hole of the copper busbar, it can be automatically corrected by the inclined plane and inserted smoothly. This avoids the traditional rigid pin from getting stuck or damaging the edge of the through hole due to slight misalignment, improves the success rate of clamping at one time, and reduces manual intervention.

[0017] In the specific implementation process, such as Figure 1-3As shown, this utility model provides a copper busbar rolling machine including a worktable 3 with an opening. A rolling disc 5 is vertically guided and installed in the opening, and a locking mechanism is installed inside the rolling disc 5. A drive assembly 6 is installed below the worktable 3, and an auxiliary rolling mechanism is installed on the top of the worktable 3, located on one side of the rolling disc 5. A limit roller 12 assembly is installed between the guide mechanism and the auxiliary rolling mechanism. The drive assembly 6 drives the rolling disc 5 to rotate, rolling the copper busbar 1 and performing vertical telescopic movement to complete demolding. The drive assembly 6 includes a mechanism to drive the rolling disc 5. The rotating motor and the lifting device that drives the winding reel 5 to move up and down are included. A through hole 2 is provided at the end of the copper busbar 1. A guide mechanism is installed on the top of the worktable 3. The guide mechanism consists of two guide rollers 7 arranged vertically and horizontally, rotating actively, with at least two sets arranged horizontally. The copper busbar 1 is located between the two guide rollers 7. The auxiliary winding mechanism has rollers 18 that roll the copper busbar 1 towards the winding reel 5, and an elastic structure that drives the rollers 18 to adaptively adjust the distance from the winding reel 5. The elastic structure includes a fixed... Positioning plate 15, movable plate 17 spaced apart from positioning plate 15 and used for rotating mounting roller 18, spring 16 between positioning plate 15 and movable plate 17, electric push rod 13 fixedly connected to one side of positioning plate 15, mounting plate 14 fixedly connected to one end of electric push rod 13, bottom of mounting plate 14 fixedly connected to top of worktable 3, limiting roller 12 assembly installed between guide mechanism and auxiliary winding mechanism and corresponding to positioning groove, limiting copper busbar 1 on both sides, the axial section of limiting roller 12 is I-shaped, limiting roller 12 assembly The worktable 3 includes a guide rail 8, a slider 9, a mounting base 10, an electric actuator 11, and a limiting roller 12. The top of the worktable 3 has a mounting groove. The top of the inner wall of the mounting groove is fixedly connected to the bottom of the guide rail 8. The top of the guide rail 8 is slidably connected to the bottom of the slider 9. The top of the slider 9 is fixedly connected to the bottom of the mounting base 10. The side of the mounting base 10 away from the copper busbar 1 is fixedly connected to the output end of the electric actuator 11. One end of the electric actuator 11 is fixedly connected to one side of the worktable 3. The top of the mounting base 10 is fixedly connected to the bottom of the limiting roller 12. It should be noted that the outer wall of the rolling disc 5 has an inwardly curved positioning groove, the width of which is slightly larger than the thickness of the copper busbar 1 (e.g., 0.2~0.5mm larger), and the depth is not less than 1 / 2 of the width of the copper busbar. This groove is used to guide the insertion of the end of the copper busbar 1 and prevent radial offset. The motor and the lifting device are controlled by the same control system. The working process is as follows: first, the motor is started to drive the rolling disc 5 to rotate, completing the rolling of the copper busbar 1. After the rolling is completed, the motor stops, the lifting device starts, and drives the rolling disc 5 to rise vertically to achieve demolding. After demolding, the lifting device resets, ready for the next cycle. The roller 18 is a polyurethane-coated wheel with a smooth, burr-free surface to prevent scratching the surface of the copper busbar 1. The spring 16 is a compression spring. The clamping force can be set by adjusting the distance between the positioning plate 15 and the mounting plate 14 to adapt to the clamping requirements of copper busbars 1 of different thicknesses; the electric push rod 2 13 is used to adjust the position of the mounting plate 14 of the auxiliary winding mechanism; the electric push rod 11 drives the mounting seat 10 to slide along the guide rail 8, thereby adjusting the lateral distance between the limiting roller 12 and the winding disc 5 to adapt to copper busbars 1 of different widths; the axial section of the limiting roller 12 is I-shaped, and its two side flanges can prevent the copper busbar 1 from shifting or warping during the transmission process, ensuring that it always enters the positioning groove along the predetermined path; at least one set of limiting roller 12 assemblies is set along the transmission direction of the copper busbar 1, located at the exit of the guide mechanism and the entrance of the auxiliary winding mechanism respectively, forming continuous limiting.

[0018] In the specific implementation process, refer to Figure 4-5 As shown, this utility model provides a copper busbar winding machine. A positioning groove for inserting a copper busbar 1 is formed on the outer wall of the winding disc 5. A locking mechanism is located above the positioning groove. The locking mechanism includes a telescopic driver 19, a positioning block 20, a universal ball 21, a limiting hemisphere 22, a rotating hemisphere 23, a connecting hemisphere 24, and a positioning cone rod 25. The telescopic driver 19 is installed inside the winding disc 5. The output end of the telescopic driver 19 is fixedly connected to the bottom of the positioning block 20. The top inner wall of the positioning block 20 is fixedly connected to the outer wall of the universal ball 21. The top is fixedly connected to the bottom of the limiting hemisphere 22, the universal ball 21 is located in the inner wall of the limiting hemisphere 22, the inner wall of the limiting hemisphere 22 is rotatably connected to the outer wall of the connecting hemisphere 24, the bottom inner wall of the connecting hemisphere 24 is fixedly connected to the top outer wall of the rotating hemisphere 23, the bottom inner wall of the rotating hemisphere 23 is rotatably connected to the outer wall of the universal ball 21, the top of the connecting hemisphere 24 is fixedly connected to the bottom of the positioning cone rod 25, the inside of the rolling disc 5 is provided with a cavity 4 for accommodating the locking mechanism, and the cavity 4 is provided with an opening that communicates with the positioning groove and is adapted to the positioning shaft; It should be noted that the locking mechanism is used to align the through hole 2 at the end of the copper busbar 1 with the positioning groove on the rolling disc 5, and then automatically insert the positioning cone rod 25 into the through hole 2 to fix the copper busbar 1 axially and prevent axial slippage during the rolling process. During operation, the telescopic driver 19 pushes the positioning block 20 downward, causing the positioning cone rod 25 to extend downward. When the positioning cone rod 25 approaches the through hole of the copper busbar 1, its floating structure allows for fine adjustment of the angle and position, achieving automatic centering and smooth insertion. The universal ball 21 is a standard ball joint structure, with its ball head embedded in the ball socket at the top of the positioning block 20. It serves as the base for the rotating hemisphere 23, the connecting hemisphere 24, and the positioning cone rod 25 to achieve angle floating adjustment of the through hole 2 of the copper busbar 1, facilitating the smooth insertion of the positioning cone rod 25. The connecting hemisphere 24 is pressed by the limiting hemisphere 22. The connecting hemisphere 24 is allowed to tilt freely within a range of ±5°. The connecting hemisphere 24 and the rotating hemisphere 23 form a rotary pair, allowing the positioning cone 25 to rotate synchronously with the copper busbar 1 during the rolling process, preventing it from twisting and breaking. The bottom of the positioning cone 25 is fixed to the top of the connecting hemisphere 24 by a pin, ensuring reliable force transmission. The telescopic actuator 19 is an electric push rod, pneumatic cylinder, or hydraulic cylinder, preferably a servo electric cylinder with position feedback, which can accurately control the extension or retraction stroke. The floating structure can achieve ±1mm offset compensation in the X-axis or Y-axis direction, and the angle compensation range is ±5°, which is sufficient to cope with the positioning error during the copper busbar 1 conveying process. The surface of the universal ball 21 is chrome-plated to improve wear resistance. The limiting hemisphere 22 is screwed into the positioning block 20 by threads and is equipped with anti-loosening washers or locking glue to prevent vibration from loosening.

[0019] The working principle provided by this utility model is as follows: The copper busbar 1 to be processed is placed into the guiding mechanism, and two or more sets of actively rotating guide rollers 7 (set at intervals) rotate synchronously to smoothly transport the copper busbar 1 to the rolling area. The copper busbar 1 runs between the upper and lower rollers to prevent warping or deviation. When the electric actuator 11 is activated, it pushes the mounting base 10 to slide along the guide rail 8. The slider 9 slides on the guide rail 8, which drives the I-shaped limiting roller 12 to move laterally and adjust it to a position that matches the current width of the copper busbar 1 (automatically set by the system). This achieves limiting of the flanges on both sides to prevent lateral displacement or warping. At least two sets of limiting rollers are set (at the guide outlet and the auxiliary winding inlet) to form continuous guidance. When the electric actuator 13 is activated, it pushes the mounting plate 14 to move the entire auxiliary winding mechanism toward the winding disc 5. Under the action of the positioning plate 15 and the spring 16, the movable plate 17 brings the roller 18 close to the winding disc 5. The roller 18 is a polyurethane coated wheel with a smooth surface to prevent scratching the copper busbar 1. The preload of the spring 16 has been set according to the thickness of the copper busbar to ensure proper compression. The front end of the copper busbar 1 continues to advance, and its end is inserted into the arc-shaped positioning groove on the outer ring wall of the coiled disc 5. The width of the positioning groove is 0.2~0.5mm larger than the thickness of the copper busbar, and the depth is ≥1 / 2 of the width of the copper busbar, to ensure stable embedding and prevent radial slippage. When the telescopic actuator 19 (servo electric cylinder) is activated, it pushes the positioning block 20 to move downward, which in turn drives the positioning cone rod 25 to extend downward. When it approaches the end through hole 2 of the copper busbar 1: the universal ball 21 acts as a ball joint base, allowing the overall structure to offset within ±1mm in the X-axis or Y-axis direction. The connecting hemisphere 24 can tilt ±5° under the constraint of the limiting hemisphere 22 to achieve angle compensation. The front end of the positioning cone rod 25 is tapered, which automatically centers and smoothly inserts into the through hole 2 to achieve axial fixation of the copper busbar 1 and prevent slippage during the rolling process. The control system starts the motor in the drive assembly 6, which drives the winding disc 5 to rotate. Under the guidance of the positioning groove, the copper busbar 1 is gradually rolled into a circle. During the rolling process: the positioning cone rod 25 rotates synchronously with the copper busbar 1 through the rotating pair formed by the rotating hemisphere 23 and the connecting hemisphere 24 to avoid twisting and breaking. The auxiliary winding mechanism roller 18 continuously applies radial pressure under the elastic force of the spring 16 to assist in forming and prevent wrinkling. The system detects the rolling angle through the encoder and automatically stops after reaching the set value (including overwind compensation). When the motor stops, the control system commands the telescopic driver 19 to retract, the positioning cone 25 to be pulled out of the copper busbar through hole 2, the lock is released, the electric push rod 13 drives the auxiliary winding mechanism to return to its original position, and the roller 18 moves away from the winding disc 5. When the lifting device is activated, the winding disc 5 is lifted vertically along the straight guide structure. The wound copper busbar rings fall off the winding disc 5 due to gravity or slight vibration and fall into the collection area below. The lifting process is smooth and without scratches, protecting the surface quality of the copper busbar. The lifting device resets, the reel 5 returns to its initial height, the limit roller 12 can maintain its current position or automatically adjust according to the next batch, and the system enters standby mode to prepare for the next cycle.

[0020] This copper busbar rolling machine has the following advantages: 1. The composite floating structure consisting of the universal ball 21, the limiting hemisphere 22, the connecting hemisphere 24, and the rotating hemisphere 23 allows the positioning cone 25 to be freely adjusted within ±1mm offset in the X-axis or Y-axis direction and ±5° angle. This effectively compensates for the positional error during the copper busbar 1 conveying process and avoids jamming or damage to the through hole caused by rigid insertion. The front end of the positioning cone 25 is tapered, which facilitates automatic centering insertion into the through hole 2 and improves the success rate of locking at one time. 2. Two or more sets of actively rotating guide rollers 7, spaced vertically, form a "clamping" conveyor to prevent the copper busbar 1 from warping or slipping. Synchronous drive ensures smooth operation and is suitable for copper busbars 1 of different lengths. The axial section of the limiting roller 12 is I-shaped, and the flanges on both sides effectively restrict the lateral movement of the copper busbar 1, preventing lateral deviation or jumping during high-speed feeding or the initial bending stage. The electric push rod 11 drives the mounting base 10 to slide along the guide rail 8, realizing automatic adjustment of the limiting width. Multiple specifications can be preset and switched with one key, making it suitable for flexible production lines. The entire process from feeding to rolling is "stable, accurate, and without deviation," ensuring the consistency of subsequent rolling quality.
