Description

Technical Field

[0001] This application relates to the field of copper busbar welding fixtures, and more specifically, to a copper busbar welding processing apparatus. Background Technology

[0002] Copper busbar flexible connectors are a type of flexible conductive device used in the power batteries of new energy vehicles. They utilize the elasticity of flexible expansion joints for protection, preventing the breakage of switches or busbars due to short circuits or thermal expansion and contraction. They are also unrestricted in terms of assembly angle, easy to install, and highly flexible. In particular, they have fast heat dissipation and good conductivity, making them widely used for conductive applications in lithium battery modules of new energy vehicles. Power batteries consist of multiple batteries stacked in series. To increase driving range, new energy electric vehicles require a large number of lithium battery modules, each composed of several battery boxes, resulting in a complex spatial arrangement. To adapt to different working environments, copper foil is used as the material for flexible connectors. Multiple copper foil sheets are stacked neatly according to specifications, and a polymer diffusion welding machine is used to weld the overlapping surfaces at both ends of the flexible connector to solidify the multiple layers of copper foil.

[0003] Patent document CN115365738A discloses a welding fixture and welding machine for copper busbars used in new energy vehicles. This invention belongs to the field of copper busbar welding fixture technology, and in particular, a welding fixture and welding machine for copper busbars used in new energy vehicles. It includes a clamping mechanism, which includes a first clamping rod, a second clamping rod, and a fixing rod. The first clamping rod and the second clamping rod both compress and fix the surface of the copper busbar through the fixing rod. In the above application, the extrusion block is pressed down in the slot, and the lower end of the extrusion block is used to expand the vertical angle between the first clamping rod and the second clamping rod, so that the first clamping rod and the second clamping rod cooperate to clamp and fix the copper busbar through the fixing rod. However, when the first clamping rod and the second clamping rod clamp the copper busbar, the copper busbar may not be able to fit tightly with the inner side of the first clamping rod and the second clamping rod, which makes it easy to cause skewing after clamping. It is not convenient to push the copper busbar inward during clamping, and it is not convenient to make the copper busbar fit tightly with the first clamping rod and the second clamping rod.

[0033] Example 1, see Figures 1-8This embodiment provides a copper busbar welding processing device, including a support plate 1, a welding device 2 fixedly installed above the support plate 1, and a movable welding head 3 arranged below the welding device 2. The movable welding head 3 is part of the welding device 2, has an electric telescopic component, and can extend and retract downwards for welding items. This is prior art. A back plate 4 is fixedly connected above the support plate 1. A first clamping rod 401 and a second clamping rod 402 are rotatably connected to the front of the back plate 4. The first clamping rod 401 and the second clamping rod 402 are specifically shaped as a straight bar with rods protruding forward at both ends.

A support member 5 is disposed below the copper busbar body 403. The support member 5 includes two support bars 501, which are fixedly connected to the upper part of the support plate 1. Two rotating rollers 502 are rotatably connected to the front of the support bars 501. The rotating rollers 502 are movably fitted to the lower part of the copper busbar body 403, and the copper busbar body 403 is placed on the rotating rollers 502 to facilitate its placement between the first clamping rod 401 and the second clamping rod 402. A rotating column 404 is rotatably connected to the upper part of the support plate 1, and a lever is fixedly connected to the outer surface of the rotating column 404. The movable block 405 is circular and eccentrically positioned on the rotating column 404. A gear 406 is fixedly connected to the outer surface of the rotating column 404. The gear 406 is cylindrical and relatively thick. A first rack 407 meshes with the left side of the gear 406. The first rack 407 is slidably connected to the upper part of the support plate 1. A protruding slide bar is provided on the upper part of the support plate 1 for sliding the first rack 407. A slide groove is provided below the first rack 407 for sliding. A pusher 6 is provided on the upper part of the back plate 4. The pusher 6 includes a support base 601, which is C-shaped and fixedly connected to the rear of the back plate 4. An electric push rod 602 is fixedly connected to the top of the inner surface of the support base 601. A push block is fixedly connected to the lower end of the electric push rod 602. 603. A first spring 604 is fixedly connected to the top of the inner surface of the support base 601. A hinge arm 605 is hinged to the lower end of the first spring 604. The hinge arm 605 includes two long strips that are hinged to each other. The left and right ends of the hinge arm 605 are respectively hinged to the upper ends of the first clamping rod 401 and the second clamping rod 402. A hydraulic component 7 is provided between the pushing member 6 and the first rack 407. The hydraulic component 7 includes a first hydraulic chamber 701, which contains liquid. The first hydraulic chamber 701 is fixedly connected to the left side of the support base 601. A first hydraulic rod 702 is slidably connected to the inner surface of the first hydraulic chamber 701. The first hydraulic rod 702 is L-shaped and is slidably connected to the first hydraulic chamber 701 via a piston.In its normal state, the first hydraulic rod 702 extends into the upper middle part of the first hydraulic chamber 701. The first hydraulic rod 702 is fixedly connected to the left side of the push block 603. A second hydraulic chamber 703 is fixedly connected to the front of the back plate 4. A flexible hose 704 connects the second hydraulic chamber 703 and the first hydraulic chamber 701, providing communication between them. A second hydraulic rod 705 is slidably connected to the inner surface of the second hydraulic chamber 703, and is slidably connected to the second hydraulic chamber 703 via a piston. The second hydraulic rod 705 is fixedly connected to the rear of the first rack 407. A grinding component 8 for grinding the welded end face is mounted on the right side of the copper busbar body 403, and a feeding component 9 for facilitating material feeding is mounted on the left side of the copper busbar body 403.

[0034] In practical use, the copper busbar body 403 to be welded is first placed above the rotating rollers 502 on the front of the two support bars 501, so that the copper busbar body 403 is between the first clamping rod 401 and the second clamping rod 402, and the right end of the copper busbar body 403 is in contact with the grinding machine 804. Then, the electric push rod 602 is activated to extend it. The extension of the electric push rod 602 will push the push block 603 down. The descent of the push block 603 will push the first clamping rod 401 and the second clamping rod 402, increasing their vertical angle. At this time, the lateral angle between the first clamping rod 401 and the second clamping rod 402 will decrease, thereby clamping the copper busbar body 403 tightly. As the push block 603 descends, it will also drive the first hydraulic rod 702 to descend. The descent of the first hydraulic rod 702 will... The first hydraulic chamber 701 slides downwards, thereby drawing liquid from the second hydraulic chamber 703 through the hose 704. This causes the second hydraulic rod 705 to retract into the second hydraulic chamber 703. At this time, the second hydraulic rod 705 pulls the first rack 407 to slide backwards. The backward sliding of the first rack 407 causes the gear 406 to rotate clockwise. The clockwise rotation of the gear 406 causes the rotating column 404 to rotate clockwise. At this time, the actuating block 405 rotates clockwise with the rotating column 404 and pushes against the front of the copper busbar body 403, so that the copper busbar body 403 is completely inserted into the first clamping rod 401 and the second clamping rod 402 and fits against the inner wall of the first clamping rod 401 and the second clamping rod 402. This facilitates positioning the copper busbar body 403 when clamping it, so that the copper busbar body 403 is in a constant Y-axis clamping position.

[0035] Example 2, see Figures 1-8The grinding assembly 8 includes a slide rail 801 with a trapezoidal cross-section. The slide rail 801 is fixedly connected to the upper part of the support plate 1. A sliding seat 802 is slidably connected above the slide rail 801. A dovetail groove is provided below the sliding seat 802 for sliding on the slide rail 801. A limiting block 803 is movably fitted to the left side of the sliding seat 802. The limiting block 803 is fixedly connected to the upper part of the support plate 1. A grinding machine 804 is fixedly installed above the sliding seat 802. The grinding machine 804 includes a motor and a... A grinding wheel, a prior art technology, is used for grinding. The grinding assembly 8 also includes a support plate 805, which is U-shaped and fixedly connected to the upper part of the support plate 1. A second rack 806 is slidably connected to the front of the support plate 805. A protruding slide bar is provided on the support plate 805 for the second rack 806 to slide left and right. A groove is provided on the back of the second rack 806 for sliding. The second rack 806 meshes with a gear 406 at the rear. The second rack 806 is offset from the first rack 407, and is positioned above the first rack 407. A telescopic rod 807 is fixedly connected to the right end of the second rack 806. A hydraulic pipe 808 is fixedly connected above the bearing plate 1. A square support is located below the hydraulic pipe 808 for fixing it. Liquid is contained within the hydraulic pipe 808. The hydraulic pipe 808 has two right-angle bends. A first piston rod 809 is slidably connected to the inner surface of the hydraulic pipe 808. A top plate 810 is fixedly connected to the left end of the first piston rod 809, which is located at the left end of the hydraulic pipe 808. A second spring 811 is elastically connected between the top plate 810 and the left end of the hydraulic pipe 808. A second piston rod 812 is slidably connected to the inner surface of the hydraulic pipe 808. The second piston rod 812 is located at the right end of the hydraulic pipe 808. The second piston rod 812 is fixedly connected to the left side of the sliding seat 802. A third spring 813 is elastically connected between the sliding seat 802 and the right end of the hydraulic pipe 808.

[0036] In practical use, when gear 406 rotates clockwise, it also causes the second rack 806 to slide to the right on the support plate 805. At this time, the second rack 806 will drive the telescopic rod 807 to move to the right, causing the telescopic rod 807 to push against the top plate 810. At this time, the telescopic rod 807 will retract to delay pushing against the top plate 810. When the telescopic rod 807 is fully retracted, the continued sliding of the second rack 806 to the right will drive the telescopic rod 807 to push against the top plate 810, causing the first piston rod 809 to extend into the liquid. Inside the hydraulic tube 808, the second spring 811 is compressed, pushing the liquid inside the hydraulic tube 808 through the first piston rod 809, thereby pushing out the second piston rod 812 at the other end of the hydraulic tube 808. The second piston rod 812 slides to the right, pushing the sliding seat 802 to slide to the right on the slide rail 801. As the sliding seat 802 moves away from the hydraulic tube 808, the third spring 813 is stretched. The sliding seat 802 then moves to the right, causing the grinder 804 to slide to the right. After leaving the copper busbar body 403, space is made for the movable welding head 3. The movable welding head 3 on the welding equipment 2 then descends to contact the copper busbar body 403 for welding. After welding, the movable welding head 3 is removed. At this point, the electric push rod 602 pulls the push block 603 upwards to loosen the fixation on the copper busbar body 403. The push block 603 then drives the first hydraulic rod 702 to push the liquid in the first hydraulic chamber 701 into the second hydraulic chamber 703, causing the second hydraulic rod 705 to move towards the second hydraulic chamber 703. The first rack 407 extends outward, causing it to slide forward, which in turn causes the gear 406 to rotate counterclockwise. The counterclockwise rotation of the gear 406 causes the second rack 806 to slide to the left, so that the telescopic rod 807 no longer presses against the top plate 810. At this time, the second spring 811 and the third spring 813 will elastically reset, causing the sliding seat 802 to slide to the left and drive the polishing machine 804 to move to the left and re-fit with the copper busbar body 403. At this time, the polishing machine 804 is started to polish the welding end face of the copper busbar body 403.

[0037] Example 3, see Figures 1-6The feeding assembly 9 includes a connecting plate 901, which is inclined and fixedly connected to the upper part of the support plate 1. A feeding groove 902 is fixedly connected to the upper part of the connecting plate 901 and is located below the copper busbar body 403. A receiving groove 903 is provided on the left side of the support plate 1 to receive the connecting rod 907. A base plate 904 is hinged to the lower part of the support plate 1, with a gap between the base plate 904 and the support plate 1. The base plate 904 and the support plate 1 are hinged together by a hinge seat located slightly to the right of the middle of the support plate 1. The feeding assembly 9 also includes a first top block 905, which is fixedly connected to the top of the base plate 904. A second top block 906 is slidably connected above the first top block 905. Inclined surfaces are provided on the first top block 905 and the second top block 906. The second top block 906 is slidably connected to the bottom of the support plate 1. A connecting rod 907 is fixedly connected above the second top block 906. The connecting rod 907 is L-shaped and is fixedly connected to the left end of the second rack 806. The sliding of the second rack 806 can drive the connecting rod 907 to make the second top block 906 slide.

[0038] In practical use, when the second rack 806 moves to the right, it will drive the connecting rod 907 to make the second top block 906 slide to the right on the first top block 905. The planes between the second top block 906 and the first top block 905 will slide against each other. At this time, the distance between the bearing plate 1 and the base plate 904 remains constant. When the second rack 806 moves to the left, it will drive the connecting rod 907 to make the second top block 906 slide to the left on the first top block 905. At this time, the second top block 906 will leave the first top block 905. After the bearing plate 1 loses its support, it will cause the components above it to tilt to the left. At this time, the copper busbar body 403, which has been loosened, will tilt to the left. The rotating roller 502 will rotate and slide the copper busbar body 403 to the left into the unloading groove 902 so as to unload the welded copper busbar body 403.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
