Description

Technical Field

[0001] This invention relates to the field of aluminum busbar welding technology, specifically to an aluminum busbar positioning welding device and method. Background Technology

[0002] Aluminum busbars are conductive connecting materials made of pure aluminum. They effectively reduce the weight of components in fields such as power electronics, automotive electronics, and photovoltaics. They can efficiently transfer heat in high-power equipment and maintain stable operating temperatures. They can be bent, punched, and processed as needed, flexibly adapting to various application scenarios. They play a wide role in many fields and powerfully promote the performance improvement and functional expansion of related equipment.

[0003] The Chinese patent application number 2024100618879 describes a welding device for aluminum busbars with positioning function. It uses a fixed stop bar to limit the rear end of the aluminum busbar, and the limiting plate can fix and clamp the aluminum busbar. The cable is placed between the pressure block and the clamping block. The toothed groove is set to prevent the cable from being skewed. The clamping block moves synchronously with the second nut seat. The welding end of the cable can be overlapped on the surface of the aluminum busbar. The positioning is accurate and the welding operation is convenient.

[0004] However, in the actual use of the above equipment, although it can achieve precise positioning of the welding end of the ribbon cable and the surface of the aluminum busbar, in the actual production process, due to factors such as operating accuracy, tool wear or unstable process parameters, some of the wire harnesses in the ribbon cable are prone to local deformation or bending after stripping.

[0005] Furthermore, during the transfer of cabling, collisions with handling tools, stacking and squeezing, or bumps and vibrations during transportation can easily cause the cabling to bend and deform. When these bent cablings are directly welded to the aluminum busbar, because the bent parts cannot fit tightly against the aluminum busbar, some cablings inevitably remain unwelded. This welding defect seriously affects the conductivity, stability, and overall welding quality of the welded joint, reduces the performance and reliability of the product, and poses a great safety hazard and performance bottleneck to the normal operation of the equipment.

[0006] To address the aforementioned technical shortcomings, a solution is proposed. Summary of the Invention

[0007] The purpose of this invention is to provide an aluminum busbar positioning and welding device and method to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: an aluminum busbar positioning and welding device, comprising a support base, a frame arranged above the support base, a reciprocating support seat slidably connected to the top of the support base, a base support fixedly installed at the top center of the reciprocating support seat, a linkage frame arranged above the base support, and a busbar combing component arranged on the top of the base support.

[0009] The cable management assembly includes two flat push plate frames, a management module, a pressing contact block, a bottom push plate frame, and a top push plate frame set inside the linkage frame. A positioning frame is symmetrically fixedly installed on the top of the bottom support platform. A push rod is slidably connected inside the positioning frame, and the push rod is located outside the positioning frame and fixedly connected to the side wall of the flat push plate frame.

[0010] Furthermore, an installation groove is provided at the top center of the bottom support platform, and the bottom push plate frame is slidably connected in the installation groove. Multiple combing modules are fixedly installed on the side wall of the flat push plate frame, the top of the bottom push plate frame, and the bottom of the top push plate frame. Abutting contact blocks are fixedly installed at the end of the flat push plate frame, the end of the top push plate frame, and the top of the bottom support platform.

[0011] Furthermore, the positioning frame has a slider slidably connected inside it through a groove at the top. The bottom end of the slider is fixedly connected to the top of the push rod. A pressing module is fixedly installed inside the linkage frame on both sides of the top push plate frame. A flat pressing module that cooperates with the pressing module is fixedly connected to the top of the slider.

[0012] Furthermore, multiple sets of limiting sleeves are fixedly installed on the top of the reciprocating support seat and on both sides of the base platform by bolts. A limiting rod is fixedly installed on the bottom of the linkage frame, and the limiting rod is slidably connected in the limiting sleeve. Support arms are fixedly connected to both ends of the linkage frame, and rollers are movably connected to the side walls of the support arms through bearings.

[0013] Furthermore, rails are fixedly installed on both sides of the bottom of the frame by bolts, and the side walls where the two rails are connected are provided with rail grooves, and rollers are slidably connected in the rail grooves.

[0014] Furthermore, the top of the supporting base is respectively provided with a receiving platform and a sliding seat. A material discharge groove is opened at the center of the top of the receiving platform. Multiple sets of electric push rods are fixedly installed on the top of the receiving platform and on both sides of the material discharge groove. The output end of the electric push rod is fixedly connected to a clamping frame.

[0015] Furthermore, a lifting plate is provided above the sliding seat, and the lifting plate and the sliding seat are connected by a lifting cylinder. The side wall of the lifting plate has multiple sets of slots, and multiple sets of electric grippers are rotatably connected in the slots.

[0016] Furthermore, the receiving platform is fixedly connected to the top of the support base, and the sliding seat is slidably connected to the top of the support base.

[0017] The present invention also proposes a method for positioning and welding aluminum busbars, comprising the following steps: placing and tightening the busbars, combing the busbars, tightening the busbars and relieving stress, placing the aluminum busbars and preparing for welding, and welding operation.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. In use, this invention achieves precise combing and stabilization of the wiring harness through the cooperation of structures such as track grooves, rollers, pressing modules, and flat pressing modules. The numerous combing modules on the top push plate frame, flat push plate frame, and bottom push plate frame comb the wiring harness from multiple directions to make it neat. At the same time, the pressing contact block immediately presses against the wiring harness after combing to overcome the stress of the wiring harness and prevent it from springing back and bending. It is also in contact with the end of the wiring harness before feeding to prevent sagging and stress deformation.

[0020] 2. When using this invention, the aluminum busbar is positioned and fixed by the automatic feeding system, and then the contact block is released from the end of the cable in a timely manner. The aluminum busbar achieves tight and effective contact with the bottom of the cable. The entire process does not require moving the cable, avoiding secondary damage or positional deviation that may be caused by cable movement, and greatly improving the efficiency and accuracy of welding.

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1: As Figures 1-7 As shown, an aluminum busbar positioning and welding equipment includes a support base 1, a frame is provided above the support base 1, a welding mechanism for welding aluminum busbars is installed on the top of the inner wall of the frame, the welding mechanism is prior art, a reciprocating support seat 2 is slidably connected to the top of the support base 1, a bottom support platform 3 is fixedly installed at the top center of the reciprocating support seat 2, and a linkage frame 4 is provided above the bottom support platform 3.

[0032] The top of the support base 1 is respectively provided with a receiving platform 17 and a sliding seat 18, and the top of the base platform 3 is provided with a cable management assembly, such as... Figure 1 and Figure 2 As shown, the top of the support base 1 has multiple sets of guide grooves. Threaded rods are movably connected to the guide grooves via bearings and are driven by motors installed on the outer side of the support base 1. The bottom of the reciprocating support 2 and the bottom of the sliding seat 18 are threadedly connected to the corresponding threaded rods. The reciprocating movement of the reciprocating support 2 and the sliding seat 18 is achieved by driving them with an external motor. It should be noted that the external driving method for the reciprocating support 2 and the sliding seat 18 is not limited to the combined drive of the threaded rod and the motor.

[0033] A feeding slot is provided at the top center of the receiving platform 17. The feeding slot at the top of the receiving platform 17 is used to place the ribbon cable. When placing the ribbon cable, the part to be welded should be placed on the outside of the receiving platform 17 to facilitate subsequent combing and welding. Multiple sets of electric push rods are fixedly installed on the top of the receiving platform 17 and on both sides of the feeding slot. The output end of the electric push rod is fixedly connected to the clamping frame 19. The clamping frame 19 on both sides of the feeding slot adaptively clamps the ribbon cable under the action of the motor to prevent the ribbon cable from shifting during the combing and welding process, which would affect the accuracy of subsequent processing.

[0034] A lifting plate 20 is provided above the sliding seat 18. The lifting plate 20 and the sliding seat 18 are connected by a lifting cylinder. The side wall of the lifting plate 20 has multiple slots. Multiple electric grippers 21 are rotatably connected in the slots. The receiving platform 17 is fixedly connected to the top of the bearing base 1. The sliding seat 18 is slidably connected to the top of the bearing base 1. The electric grippers 21 are existing mechanisms. The lifting plate 20 is used to place aluminum bars.

[0035] Once the aluminum busbar is placed on top of the lifting plate 20, the electric gripper 21 rotates to clamp and position the side wall of the aluminum busbar, preventing displacement during transport and welding that could reduce welding precision. Figure 1 As shown, the position of the receiving platform 17 does not affect the movement of the sliding seat 18 or the automatic feeding of the aluminum busbar.

[0036] Example 2: The cable management component of this example includes two flat push plate frames 501, a management module 502, a pressing contact block 503, a bottom push plate frame 504, and a top push plate frame 505 set inside the linkage frame 4. A positioning frame 10 is symmetrically fixedly installed on the top of the bottom support 3. A push rod 11 is slidably connected inside the positioning frame 10. A compression spring is connected to the inner side wall of the positioning frame 10, and the other end of the compression spring is fixedly connected to the end of the push rod 11. The push rod 11 can reset itself without external force. The end of the push rod 11 located outside the positioning frame 10 is fixedly connected to the side wall of the flat push plate frame 501.

[0037] A mounting groove is provided at the top center of the bottom support platform 3. The bottom push plate frame 504 is slidably connected in the mounting groove. A compression spring is fixedly connected to the bottom of the inner wall of the mounting groove, and one end of the compression spring is fixedly connected to the bottom of the bottom push plate frame 504, so that the bottom push plate frame 504 can automatically reset without external force.

[0038] Multiple combing modules 502 are fixedly installed on the side wall of the flat push plate frame 501, the top of the bottom push plate frame 504, and the bottom of the top push plate frame 505. The combing modules 502 comb the messy wire bundles at the ends of the cable, making them smooth and neat. Abutting contact block 503 is fixedly installed at the ends of the flat push plate frame 501, the ends of the top push plate frame 505, and the top of the bottom support 3.

[0039] It should be explained here that the size of the clamping contact block 503 installed in different positions is different, but the function is the same. The clamping contact block 503 is located near the combing module 502. After the cable is combed, it can be clamped in time to prevent the cable from becoming messy again. The clamping contact block 503 presses the end of the combed cable, making the cable bundle at the end of the combed cable more compact.

[0040] The positioning frame 10 has a sliding groove at the top and a slider 9 is slidably connected inside it. The bottom end of the slider 9 is fixedly connected to the top of the push rod 11. The linkage frame 4 is fixedly installed inside and on both sides of the top push plate frame 505. The top of the slider 9 is fixedly connected to a flat pressing module 7 that cooperates with the pressing module 8.

[0041] like Figure 5 and Figure 6 As shown, the bottom of the pressing module 8 and the top of the flat pressing module 7 are both set as mutually cooperating inclined surfaces. The contact cooperation between the inclined surfaces of the pressing module 8 and the flat pressing module 7 realizes the automatic sliding of the flat pressing module 7, which further drives the flat push plate frame 501 to move closer to the ribbon cable.

[0042] Multiple sets of limiting sleeves 6 are fixedly installed on the top of the reciprocating support 2 and on both sides of the base platform 3 by bolts. A limiting rod 12 is fixedly installed on the bottom of the linkage frame 4, and the limiting rod 12 is slidably connected in the limiting sleeve 6. When the linkage frame 4 moves reciprocally in the vertical direction, it cooperates with the limiting rod 12 to slide stably in the limiting sleeve 6, thereby realizing the stable lifting and lowering of the linkage frame 4. Both ends of the linkage frame 4 are fixedly connected to support arms 13, and the side walls of the support arms 13 are movably connected to rollers 14 through bearings.

[0043] The bottom of the frame is fixed to both sides by bolts with rails 15. A rail groove 16 is formed on the side wall where the two rails 15 connect, and the roller 14 is slidably connected within the rail groove 16. Figure 2 As shown, the track groove 16 is an inclined groove, and the roller 14 slides in a directional manner in the track groove 16 and drives the linkage frame 4 to reciprocate and move up and down through the support arm 13.

[0044] As can be seen from Embodiment 1 and Embodiment 2, the working principle of the present invention is as follows:

[0045] The cable is clipped into the feeding slot at the top of the receiving platform 17, and the end to be welded to the aluminum busbar end face is placed outside the feeding slot. The clamping frames 19 on both sides of the feeding slot clamp the outside of the cable under the action of the electric push rod to prevent the cable from moving during the combing and welding process. One end of the cable is placed in the space composed of the flat push plate frame 501, the top push plate frame 505 and the bottom push plate frame 504.

[0046] Under the action of the external drive mechanism, the reciprocating support 2 moves horizontally along the top of the bearing base 1. When the roller 14 moves from the high position to the low position of the track groove 16, it drives the linkage frame 4 to descend through the support arm 13. During the descent, the linkage frame 4 drives the top push plate frame 505 and the pressing module 8 to descend synchronously. The top push plate frame 505 drives the combing module 502 at its bottom to comb the top wire harness of the cable.

[0047] After the pressing module 8 comes into contact with the flat pressing module 7, it further pushes the slider 9, the push rod 11 and the flat push plate frame 501 to move synchronously until the combing module 502 on the side wall of the flat push plate frame 501 combs the wire harnesses on both sides of the cable. The bottom push plate frame 504 combs the wire harnesses at the bottom of the cable under the pressure of the top push plate frame 505 and the cable.

[0048] The top push plate frame 505, bottom push plate frame 504, flat push plate frame 501 and combing module 502 work together to comb the messy wire bundles on the surface of the ribbon cable. The combed ribbon cable is fully pressed by the abutting contact blocks 503 set at each position, making the ribbon cable more compact and facilitating precise welding in the future.

[0049] After the ribbon cable is combed and tightened, the tightening contact block 503 does not completely move out of the end of the ribbon cable. At this time, the tightening contact block 503 still effectively tightens the end of the ribbon cable, further offsetting the stress of the wire harness itself. At the same time, it can also prevent the ribbon cable from bending naturally due to its own weight. The aluminum strip is placed on the top of the lifting plate 20 and positioned and fixed on the outside by the electric gripper 21. The sliding seat 18 pushes the aluminum strip until it is close to the ribbon cable. At this time, the tightening contact block 503 further disengages from the end of the ribbon cable under the action of the reciprocating support seat 2. The aluminum strip makes effective contact with the bottom of the ribbon cable under the action of the lifting push cylinder. Then the welding mechanism descends and welds the ribbon cable and the aluminum strip.

[0050] The preferred embodiments of the present invention disclosed above are merely illustrative of the invention. These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the invention, thereby enabling those skilled in the art to better understand and utilize the invention.
