Description

Technical Field

[0001] The invention relates to the technical field of aluminum busbar wire welding, and in particular to an aluminum busbar wire positioning welding device and method. Background Art

[0002] Aluminum busbars are conductive connecting materials made of pure aluminum. They effectively reduce the weight of components in power electronics, automotive electronics, photovoltaics and other fields. They can efficiently transfer heat in high-power equipment and maintain a stable operating temperature. They can be bent, punched and processed as needed, and are flexibly adapted to a variety of application scenarios. They play a wide range of roles in many fields, and have effectively promoted the performance improvement and function expansion of related equipment.

[0003] The Chinese patent with application number 2024100618879 is specifically a welding device for aluminum busbars with a positioning function. A fixed baffle is used to limit the rear end of the aluminum busbar. The limit plate can fix and clamp the aluminum busbar. The busbar is placed between the pressure block and the clamping block. A tooth groove is provided to prevent the busbar from being skewed. The clamping block moves synchronously with the second nut seat. The welding end of the busbar can be overlapped on the surface of the aluminum busbar, which is accurately positioned and convenient for welding operations.

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

[0005] Moreover, during the transportation of the cables, collisions with handling tools, stacking and squeezing, as well as bumps and vibrations during transportation can easily cause the wiring harness to bend and deform. When these bent cables are directly welded to the aluminum bus, the bent parts cannot fit tightly with the aluminum bus, and inevitably part of the wiring harness is not welded. This welding defect seriously affects the conductivity and stability of the welding joint and the overall welding quality, reduces the performance and reliability of the product, and brings great safety hazards and performance bottlenecks to the normal operation of the equipment.

[0006] In view of the above technical defects, a solution is now proposed. Summary of the invention

[0012] Furthermore, a plurality of sets of limit sleeves are fixedly installed on the top of the reciprocating support seat and on both sides of the bottom support platform by bolts, a limit rod is fixedly installed on the bottom of the linkage frame, and the limit rod is slidably connected in the limit sleeve, and support arms are fixedly connected at 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 a rail groove is opened on the side wall where the two rails are connected, and the roller is slidably connected in the rail groove.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Embodiment 1: Figure 1-Figure 7 As shown, an aluminum row wire positioning welding device includes a bearing base 1, a frame is arranged above the bearing base 1, a welding mechanism for aluminum row wire welding is installed on the top of the inner wall of the frame, and the welding mechanism is a prior art. A reciprocating support seat 2 is installed in a sliding connection on the top of the bearing base 1, and a bottom support platform 3 is fixedly installed at the top center of the reciprocating support seat 2, and a linkage frame 4 is arranged above the bottom support platform 3;

[0032] The top of the supporting base 1 is provided with a material receiving platform 17 and a sliding seat 18, and the top of the bottom supporting platform 3 is provided with a wire arrangement and combing component. Figure 1 and Figure 2 As shown, a plurality of guide grooves are provided on the top of the bearing base 1, threaded rods are movably connected in the guide grooves through bearings, and driven by a corresponding motor installed on the outer side of the bearing base 1, while the bottom of the reciprocating support seat 2 and the bottom of the sliding seat 18 are threadedly connected to the corresponding threaded rods, and the reciprocating movement of the reciprocating support seat 2 and the sliding seat 18 is achieved by driving an external motor. It should be explained here that the external driving method of the reciprocating support seat 2 and the sliding seat 18 is not limited to the cooperative drive of the threaded rod and the motor.

[0033] A material discharge trough is provided at the top center of the material receiving table 17. The material discharge trough on the top of the material receiving table 17 is used to place the wiring harness. When placing the wiring harness, the part to be welded needs to be placed on the outside of the material receiving table 17 to facilitate subsequent combing and welding. A plurality of electric push rods are fixedly installed on the top of the material receiving table 17 and on both sides of the material discharge trough. A tightening frame 19 is fixedly connected to the output end of the electric push rod. The tightening frames 19 on both sides of the material discharge trough adaptively tighten the wiring harness under the action of the motor to avoid the problem of deviation of the wiring harness during combing and welding, which affects the subsequent processing accuracy.

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

[0035] When the aluminum bar is placed on the top of the lifting plate 20, the electric clamp 21 rotates and presses and calibrates the side wall of the aluminum bar to avoid the problem of displacement of the aluminum bar during transportation and welding, which may reduce the welding accuracy. Figure 1 As shown, the position of the receiving platform 17 does not affect the movement of the sliding seat 18 and the automatic loading of the aluminum row.

[0036] Embodiment 2: The cable combing assembly of this embodiment includes two flat pushing plate frames 501, a combing module 502, a tight contact block 503, a bottom pushing plate frame 504 and a top pushing plate frame 505 arranged inside the linkage frame 4, and a positioning frame 10 is symmetrically fixedly installed on the top of the bottom support platform 3. The internal sliding connection of the positioning frame 10 is connected with a push rod 11, and the inner side wall of the positioning frame 10 is connected with a compression spring, 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, and the push rod 11 is located at one end outside the positioning frame 10 and is fixedly connected to the side wall of the flat pushing plate frame 501.

[0037] A mounting groove is provided at the top center of the bottom support platform 3, and 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 reset itself 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 arrangement to make them smoothly and neatly arranged. 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 platform 3 are fixedly installed with tight contact blocks 503.

[0039] It needs to be explained here that the pressing contact blocks 503 installed at various positions have different sizes but the same functions, and the pressing contact blocks 503 are arranged near the combing module 502, so that the cables can be pressed in time after being combed to avoid the problem of the cables becoming messy again, and the pressing contact blocks 503 press the ends of the combed cables to make the wire harnesses of the combed cables more tightly arranged.

[0040] The positioning frame 10 is slidably connected with a slider 9 inside thereof through a slide groove provided at the top, and the bottom end of the slider 9 is fixedly connected to the top of the push rod 11, and a pressing module 8 is fixedly installed inside the linkage frame 4 and on both sides of the top push plate frame 505, and the top end of the slider 9 is fixedly connected with a flat pressing module 7 matched 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 configured as mutually matching inclined surfaces, and the contact and cooperation between the pressing module 8 and the inclined surfaces of the flat pressing module 7 are utilized to realize the automatic sliding of the flat pressing module 7, and further drive the flat pushing plate frame 501 to move closer to the cable arrangement;

[0042] A plurality of sets of limit sleeves 6 are fixedly installed on the top of the reciprocating support seat 2 and on both sides of the bottom support platform 3 by bolts. A limit rod 12 is fixedly installed on the bottom of the linkage frame 4, and the limit rod 12 is slidably connected in the limit sleeve 6. When the linkage frame 4 reciprocates in the vertical direction, the limit rod 12 slides stably in the limit sleeve 6 to achieve stable lifting of the linkage frame 4. Support arms 13 are fixedly connected at both ends of the linkage frame 4, and the side walls of the support arms 13 are movably connected with rollers 14 through bearings.

[0043] Rails 15 are fixedly installed on both sides of the bottom of the frame by bolts, and a rail groove 16 is opened on the side wall where the two rails 15 are connected, and the roller 14 is slidably connected in the rail groove 16. Figure 2 As shown, the track groove 16 is an inclined groove, and the roller 14 performs directional sliding in the track groove 16 and drives the linkage frame 4 to perform reciprocating lifting and lowering movement through the support arm 13.

[0044] Combining the first and second embodiments, it can be seen that the working principle of the present invention is as follows:

[0045] The cable is clamped in the discharge trough on the top of the receiving platform 17, and one end for welding with the end face of the aluminum cable is placed outside the discharge trough. The tightening frames 19 located on both sides of the discharge trough tighten the outer side of the cable under the action of the electric push rod to prevent the cable from moving during the combing and welding process, and one end of the cable is placed in the space formed by the flat push plate frame 501, the top push plate frame 505 and the bottom push plate frame 504;

[0046] The reciprocating support seat 2 moves horizontally along the top of the bearing base 1 under the action of the external driving mechanism. When the roller 14 moves from the high position to the low position of the track groove 16, the supporting arm 13 drives the linkage frame 4 to descend. 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 the bottom thereof to comb the top wire harness of the cable arrangement.

[0047] After the pressing module 8 contacts the flat pressing module 7, the slider 9, the push rod 11 and the flat pushing plate frame 501 are further pushed to move synchronously, until the combing module 502 on the side wall of the flat pushing plate frame 501 combs the wire bundles on both sides of the cable, and the bottom pushing plate frame 504 combs the wire bundles at the bottom of the cable under the pressure of the top pushing plate frame 505 and the cable.

[0048] The top push plate frame 505, the bottom push plate frame 504, the flat push plate frame 501 and the combing module 502 cooperate with each other to comprehensively comb the messy wire bundles on the surface of the cable arrangement, and the tightening contact blocks 503 arranged at various positions are used to fully tighten the combed cable arrangement, so that the cable arrangement is more compact and convenient for subsequent precise welding;

[0049] After the cable is combed and tightened, the tightening contact block 503 is not completely removed from the end of the cable, and the tightening contact block 503 at this time still effectively tightens the end of the cable, further offsetting the stress of the wiring harness itself, and also avoiding the problem of natural bending of the cable due to its own gravity. The aluminum bar is placed on the top of the lifting plate 20 and is positioned and fixed on the outside by the electric clamp 21. The sliding seat 18 pushes the aluminum bar until it is close to the cable. At this time, the tightening contact block 503 is further separated from the tightening of the end of the cable under the action of the reciprocating support seat 2, and the aluminum bar is effectively contacted with the bottom of the cable under the action of the lifting cylinder. Then the welding mechanism descends and welds the cable and the aluminum bar.

[0050] The preferred embodiments of the present invention disclosed above are only used to help explain the present invention. The preferred embodiments do not describe all the details in detail, nor do they limit the invention to only specific implementation methods. Obviously, many modifications and changes can be made according to the content of this specification.
