Description

TECHNICAL FIELD

[0001] The present application relates to busbar production equipment field, specifically to a multi-angle bending high-voltage busbar bending machine. BACKGROUND

[0002] The battery busbar is a strip-shaped connecting piece for connecting the battery cells, and the high-voltage busbar is a wire for the high-voltage system of the battery, which has a rectangular cross section and can replace the commonly used traditional round wire. The high-voltage busbar can be used in a relatively narrow space, such as a battery pack. When connecting each high-voltage module in the battery pack, the traditional round cable occupies a large space. Therefore, the flattened busbar can be used as a wire, which can leave additional space for the battery pack, thereby reducing the volume of the battery. In addition, since the surface area of the high-voltage busbar is larger than that of the traditional round wire, the heat dissipation capacity of the wire is improved.

[0003] At the same time, the use of rigid high-voltage busbar can facilitate the robot to grasp and assemble, so it is necessary to bend the busbar according to its assembly position during the production process. The busbar usually needs to be bent multiple times at different lengths to match the assembly position. The existing busbar bending equipment mainly includes clamp rotary bending and die stamping bending. The clamp rotary bending is to hold the busbar by a clamp and rotate the clamp by a motor to realize bending. The bending points need to be bent and fed alternately to realize sequential bending, which is low in efficiency. The stamping bending is to press and bend the busbar by the two side molds after the busbar is sent into the mold. Since the length of the inside fold line of the mold is greater than the length of the straight busbar extending into the mold, there is a problem of pulling when the multiple points of the busbar are bent synchronously, which can easily cause the internal metal wire to stretch and break or the outer protective skin to tear, affecting the product quality. SUMMARY

By setting the guide roller rolling along the bending mold bending side, the guide plate is used to support the pressure assembly sliding, thereby quickly realizing the extrusion bending of multiple bending points of the busbar.

[0037] The bottom frame 701 of the movable seat 7 is fixed with a driving rod 706 in front, the end of which is fixed with a rear supporting plate 707, the workbench 1 in front of the supporting plate 101 is fixed with a driving assembly 9, which comprises two groups of vertical shafts 902 parallel to each other and distributed transversely, the vertical shafts 902 extend vertically, the bottom ends of the two groups of vertical shafts 902 are provided with bases 901 fixed to the top of the workbench 1, the bottom ends of the vertical shafts 902 are rotatably connected to the bases 901 through bearings, the top ends of the two groups of vertical shafts 902 are fixed with belt pulleys 903, the outer sides of the two groups of belt pulleys 903 are rotatably connected with a transmission belt 904, the front side of the transmission belt 904 is fixed with a front supporting plate 905, the front supporting plate 905 is fixed with a driven rod 906 extending transversely to the outside of the connecting piece 407, and the driven rod 906 is welded and fixed with the connecting piece 407, the pressure assembly 4 is fixed to the front side of the transmission belt 904 through the driven rod 906 and the front supporting plate 905, when the telescopic end of the feeding cylinder 6 is fully retracted, the feeding cylinder 6 pulls the movable seat 7 to the feeding position, the movable seat 7 and the pressure assembly 4 are connected synchronously through the transmission belt 904, and then the feeding action and the bending action of the busbar are alternately matched, so that one feeding cylinder 6 serves as the power source for feeding the busbar and driving the pressure assembly 4 to transversely move and bend the busbar, the gas circuit structure of the equipment is simplified, and the cutting mechanism (not shown in the figure) is arranged between the fixed seat 8 and the bending die plate 3 to cut the busbar after the busbar is bent, so that the finished product of the bent busbar is cut by the cutting mechanism, and the feeding and bending actions of the next section of the busbar are facilitated.

[0038] With the above structure, when the busbar needs to be bent, the busbar is sequentially threaded between the upper clamping plate 704 and the lower clamping plate 705 of the movable seat 7 and the fixed seat 8, and it is ensured that the busbar is threaded along the trumpet-shaped trumpet cover 104 through the guide cylinder 103. At this time, it is ensured that the fixed seat 8 is in a loosened state with respect to the busbar, and the movable seat 7 is in a clamped state with respect to the busbar. Then, the feeding cylinder 6 is elongated to push the movable seat 7 to slide along the slide rail 102, so that the busbar supported by the movable seat 7 slides towards the bending die plate 3. When the busbar extends to the front of the bending die plate 3, the fixed seat 8 clamps the busbar, the movable seat 7 loosens the busbar, and the feeding cylinder 6 is retracted to pull the movable seat 7 back to the feeding position. During the process of pulling the movable seat 7 back by the feeding cylinder 6, the driving rod 706 of the movable seat 7 cooperates with the rear support plate 707 to pull the transmission belt 904 to rotate. The transmission belt 904 and the front support plate 905 and the driven rod 906 on the front surface thereof are used to support the pressure assembly 4 to slide transversely along the guide plate 5. At this time, the pressure cylinder 402 of the pressure assembly 4 pushes the pressure roller 403 to abut against the front surface of the busbar, so that the busbar is pushed into the accommodating groove 301 of the bending die plate 3 by the pressure roller 403. At the same time, the pressure assembly 4 slides along the guide groove 501 in the length direction, and cooperates with the spring 408 to push the pressure roller 403 to abut against the front surface of the bending die plate 3 at all times, so as to push the busbar along the bending die plate 3 to be bent at multiple angles by the pressure roller 403. Thus, the bending and forming process of the busbar is realized.

[0039] By arranging the guide roller that rolls along the bending side of the bending die plate 3, the pressure assembly 4 is supported by the guide plate 5 to slide, and then the extrusion bending of multiple bending points of the busbar is quickly realized. The advantages of the rotary bending of the busbar and the high efficiency of the stamping bending are combined, so as to improve the bending efficiency and ensure the product quality of the busbar.

[0040] The guide cylinder 103 is arranged to straighten the busbar before the busbar is conveyed to the bending station. The transmission belt 904 of the driving assembly 9 is used to drive the pressure assembly 4 to move transversely along the front surface of the bending die plate 3 during the process of retracting the movable seat 7 by the feeding cylinder 6.
