[0002] In recent years, with the rapid development of the electronics industry, the requirements and standards for battery assembly have been continuously improving. Against this background, a high-level battery assembly production line is particularly important for ensuring product consistency.

[0003] Since different electronic products require batteries of different sizes, corresponding connection flexible flat cables must be equipped for these batteries. The processing of "tab ears" and "flexible flat cables" becomes a key link in this process. Specifically, "tab ears" refer to the parts at both ends of the battery used to connect the external circuit; while "flexible flat cables" are flexible printed circuit boards used to connect various electronic components.

[0004] Before traditional automatic welding equipment welds a flexible flat cable, it usually needs to fix the flexible flat cable first and ensure that the welding part is not blocked. The previous operation methods often relied on operators to manually adjust the flexible flat cable, which was not only time-consuming but also likely to affect work efficiency.

Detailed implementation manners

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0025] Please refer to Figures 1-6 ;

[0026] An automatic bending mechanism for a flexible cable includes a rotary conveying device 1. A number of fixtures 2 are arranged in an annular array on the rotary conveying device 1. An adjustable clamping assembly 3 is provided on the fixture 2. The clamping assembly 3 is used to clamp the battery. By adjusting the clamping assembly 3, batteries of different sizes can be clamped. An extension 4 is provided on the fixture 2. An adjustable pressing and bonding assembly 5 for pressing and bonding the ear and the flexible cable is provided on the extension 4. A positioning device 6 is provided at the outer end of the rotary conveying device 1. A fixing plate 9 is provided on the positioning device 6. Preferably, the positioning device 6 of the present utility model is composed of a linear module and a cylinder. The linear module realizes the movement of the slider by driving the lead screw through a stepping motor, and the cylinder is arranged on the slider. The fixing plate 9 is fixedly installed at the output end of the cylinder. The fixing plate 9 is driven by the cylinder to perform a lifting movement. Since the distances between the two ears of different batteries are different, a fixed bending member 7 and a movable bending member 8 are provided on the fixing plate 9. Taking the position of the fixed bending member 7 as a reference, the position of the movable bending member 8 is adjusted so that the parts of the fixed bending member 7 and the movable bending member 8 in contact with the two ears and the flexible cable respectively correspond, thereby bending the two flexible cables simultaneously. By providing the adjustable movable bending member 8, the ears with different distances can be adapted, and the applicable range is improved. Specifically, first, the position of the movable bending member 8 is adjusted so that the parts of the fixed bending member 7 and the movable bending member 8 in contact with the two ears and the flexible cable respectively are aligned. The lifting and movement of the fixed bending member 7 and the movable bending member 8 are driven by the positioning device 6, so that the fixed bending member 7 and the movable bending member 8 bend the flexible cable. Since it is necessary to avoid blocking the parts where the flexible cable is in contact with the ear, the fixed bending member 7 and the movable bending member 8 start from the rear of the flexible cable and sweep over to bend the flexible cable, eliminating the need for manual bending of the flexible cable and improving work efficiency.

[0027] In this embodiment, the fixed bending member 7 includes a bracket 71 fixedly connected to the fixing plate 9. A first cross beam 72 is provided on the bracket 71. One end of the first cross beam 72 is provided with a downward extending bending portion 73 for bending one of the flexible cables. The movable bending member 8 includes a moving guide rail 81 provided on the fixing plate 9. A moving slider 82 is movably connected to the moving guide rail 81. A fixed seat 83 is provided on the moving slider 82. An adjusting block 84 is installed on the fixed seat 83. A second cross beam 85 is provided on the adjusting block 84. One end of the second cross beam 85 is provided with a downward extending bending portion 86 for bending the other flexible cable. A first cylinder 87 is provided on one side of the moving slider 82. The output end of the first cylinder 87 is fixedly connected to the moving slider 82. By pushing the moving slider 82 by the first cylinder 87, the position of the bending portion 86 can be adjusted, so as to achieve the purpose of bending flexible cables with different distances and improve the practicability.

[0028] Specifically, after the lamination assembly 5 presses the flexible cable and the tab firmly, the cylinder 1 87 is used to push the moving slider 82 to adjust the position of the movable bending member 8, so that the positions where the fixed bending member 7 and the movable bending member 8 are respectively in contact with the two tabs and the flexible cable are aligned. The positioning device 6 is used to lift the fixed bending member 7 and the movable bending member 8, and then move them in the direction of the flexible cable. When the first bending part 73 of the fixed bending member 7 and the second bending part 86 of the movable bending member 8 move to the rear of the flexible cable, the positioning device 6 drives the fixed bending member 7 and the movable bending member 8 to descend. When it descends to a height where the lower end surfaces of the first bending part 73 and the second bending part 86 are slightly higher than the height of the part where the lamination assembly 5 presses the flexible cable and the tab firmly, the descent stops. Then the positioning device 6 moves in the direction away from the jig 2. When the positioning device 6 moves, the first bending part 73 and the second bending part 86 respectively sweep across their corresponding flexible cables, thereby bending the two flexible cables simultaneously.

[0029] Further, an adjustment hole three 88 is provided on the adjustment block 84. The adjustment hole three 88 is an elliptical hole. The adjustment block 84 is connected to the fixed seat 83 by using a screw passing through the adjustment hole three 88, so that the position of the second bending part 86 can be manually adjusted further to make the distance between the first bending part 73 and the second bending part 86 larger.

[0030] Further, the clamping assembly 3 includes a first fixing member 31 provided on one side of the jig 2. A limiting groove 32 connected to the rotary conveying device 1 is provided on the side of the jig 2 away from the first fixing member 31. A sliding member 33 is provided on the limiting groove 32. An adjustment hole one 34 is provided on the sliding member 33. The sliding member 33 is connected to the jig 2 by using a screw passing through the adjustment hole one 34. The length of the limiting groove 32 is greater than the length of the sliding member 33. By loosening the screw, the sliding member 33 can move freely along the limiting groove 32 to adjust the distance between the sliding member 33 and the first fixing member 31, so as to fix batteries of different sizes.

[0031] In this embodiment, the lamination assembly 5 includes two spaced positioning blocks 51. Adjustment holes two 52 are provided on both of the two positioning blocks 51. Both of the two positioning blocks 51 are connected to the jig 2 by using screws passing through the adjustment holes two 52. By loosening the screws, the positions of the two positioning blocks 51 can be adjusted according to the distance between the battery tabs. Avoidance spaces 53 are provided on both of the two positioning blocks 51. The tabs extend out from the avoidance spaces 53. A concave step 54 is provided on the side of the avoidance space 53 away from the jig 2. The end of the tab is bent manually at the position of the concave step 54.

[0032] In addition, the pressing assembly 5 further includes a second cylinder 55. The output end of the second cylinder 55 is fixedly connected with a second fixing member 56. The second fixing member 56 is driven to move by the second cylinder 55. A pressing member 57 is installed on the second fixing member 56. The pressing member 57 is connected to the second fixing member 56 by using screws to pass through its side wall. When the second fixing member 56 moves, the pressing member 57 is driven to move together. A pressing portion 58 corresponding to the lower concave step 54 is provided on the pressing member 57. Specifically, the wiring harness is placed at the lower concave step 54 manually or automatically and abuts against the tab. Then the second cylinder 55 retracts. When the second cylinder 55 retracts, it drives the pressing portion to move towards the wiring harness direction, so as to press the wiring harness and the bent portion of the tab together.
