[0056] Reference Figure 1-Figure 6 The present invention provides a battery assembly production line, comprising:

[0057] A base 1, a conveyor belt assembly 2 is vertically arranged on the top of the base 1, a plurality of placement seats 12 are fixedly connected to the conveyor belt assembly 2 at equal intervals, and placement holes 39 are respectively opened on the top and bottom of the placement seat 12, and the placement holes 39 are used to place the battery aluminum shell 13;

A welding assembly and an insulating sheet pasting assembly are respectively arranged in the front bracket 3 from bottom to top. An insulating sheet conveyor belt assembly 43 is arranged on one side of the conveyor belt assembly 2.

The insulating sheet pasting assembly and the insulating sheet conveyor belt assembly are arranged correspondingly.

[0059] The rear bracket 14 has a heat shrink tube sleeve assembly and a heat drying assembly arranged from top to bottom in the rear bracket 14 . The heat shrink tube sleeve assembly is used to sleeve the heat shrink tube on the battery aluminum shell 13 , and the heat drying assembly is used to heat the heat shrink tube on the battery aluminum shell 13 with hot air.

[0060] The conveyor belt assembly 2 is placed vertically, which can change the conveyor belt from occupying space horizontally to occupying space vertically; the main function of the placement seat 12 is to drive the battery aluminum shell 13 to move along the conveyor belt assembly 2; the main function of the two groups of placement holes 39 is to prevent the battery aluminum shell 13 from falling from the placement seat 12; the main function of the insulating sheet conveyor belt assembly 43 is to rotate with the conveyor belt assembly 2 to convey the insulating sheet to the insulating sheet pasting assembly; the main function of the insulating sheet pasting assembly is to paste the insulating sheet on the battery aluminum shell 13; the main function of the welding assembly is to weld the battery aluminum shell; the main function of the heat shrink tube sleeve assembly is to sleeve the heat shrink tube of appropriate length on the battery aluminum shell 13, and the main function of the heat baking assembly is to bake the heat shrink tube sleeved on the battery aluminum shell 13. On the whole, the present invention can automatically complete the production work of welding, pasting insulating sheets, and sleeve heat shrink tubes of battery aluminum shells. At the same time, by vertically arranging the conveyor belt assembly, the floor space of the automated production line is reduced by occupying the height space.

[0061] A further optimized solution is that the welding assembly includes a first cylinder 4 horizontally fixedly connected in the front bracket 3, the telescopic end of the first cylinder 4 is arranged close to the conveyor belt assembly 2, and the telescopic end of the first cylinder 4 is fixedly connected to a fixed block 5, and the side of the fixed block 5 away from the first cylinder 4 is fixedly connected to a tin nozzle 7 and a soldering iron tip 6.

[0062] like Figure 1 As shown, with the rotation of the conveyor belt assembly 2, the placement seat 12 close to the front bracket 3 side moves upward in steps. When the battery aluminum shell 13 to be welded moves to a height corresponding to the tin nozzle 7, the first cylinder 4 extends the telescopic end, driving the fixed block 5 to move toward the direction of the battery aluminum shell 13, so that the solder removed from the tin nozzle 7 corresponds to the part to be welded of the battery aluminum shell 13. At the same time, the soldering iron head 6 welds the solder to the battery aluminum shell 13 to complete the welding work of the battery aluminum shell 13.

[0063] A solder supply device is also provided, the main function of which is to make the solder extend from the tin nozzle 7. The solder attack device is a conventional device, and its structure and working process will not be described in detail.

[0064] Subsequently, the telescopic end of the first cylinder 4 is retracted, and the next battery aluminum shell 13 is moved to the processing station.

[0065] A further optimized solution is that the insulating film pasting assembly includes a driving linear guide rail 8 horizontally fixedly connected to the front bracket 3, and a moving rod 9 is vertically arranged on the driving linear guide rail 8.

A suction cup 18 is arranged at the telescopic end of the second cylinder 10, and the suction cup 18 is arranged corresponding to the insulating film on the insulating film conveyor belt assembly 43.

[0066] In a further optimized solution, the insulating sheet conveyor belt assembly 43 is connected to the conveyor belt assembly 2 through a differential transmission, so that when the conveyor belt assembly 2 rotates in steps, the insulating sheet conveyor belt assembly 43 also rotates in steps, achieving a one-to-one correspondence between the insulating sheet and the battery aluminum shell 13. The insulating sheet conveyor belt assembly 43 is a common setting, and its structure and working process will not be described in detail.

[0067] like Figure 1 As shown, when a battery aluminum shell 13 moves toward the direction of the second cylinder 10 along with the placement seat 12, before the battery aluminum shell 13 reaches the station for pasting the insulating sheet, the first height adjustment member drives the second cylinder 10 to move to a position at the same height as the insulating sheet to be picked up, and at the same time drives the second cylinder 10 to rise synchronously with the insulating sheet. At this time, the second cylinder 10 extends the telescopic end and absorbs the insulating sheet with the suction cup 18. As the insulating sheet continues to rise, when the insulating sheet moves to the top turning point of the insulating sheet conveyor belt assembly 43, the insulating sheet is gradually separated from the conveyor belt from the edge under the action of the suction cup 18, thereby avoiding the damage or failure of the insulating sheet caused by conventional violent picking of the insulating sheet.

[0068] Afterwards, the second cylinder 10 retracts and, driven by the driving linear guide rail 8, moves the insulating sheet to align with the battery aluminum shell 13. Then, the telescopic rod of the second cylinder 10 is extended again to stick the insulating sheet to the outer wall of the battery aluminum shell 13.

[0069] The suction cup 18 is provided with the negative pressure required for picking up the insulating sheet by the negative pressure device.

[0072] To further optimize the solution, a heat shrink tube delivery assembly 15 is also provided on the rear bracket 14, and the main function of the heat shrink tube delivery assembly 15 is to deliver the heat shrink tube upward to the moving plate 28. The heat shrink tube delivery assembly 15 is a conventional device, and its structure and working process are not described in detail.

[0073] like Figure 1 and Figure 2 As shown, the heat shrink tube conveying assembly 15 conveys the heat shrink tube upward, and the fifth motor 35 drives the movable disk 28 to align a conical hole 29 with the heat shrink tube. After that, the second height adjustment member drives the sliding seat 44 to move downward, and drives the movable disk 28 to move downward to a set height, so that the end of the heat shrink tube passes through the conical hole 29 and is clamped in the conical hole 29. After that, the third motor 31 is started to drive the cutter 32 to rotate. At the same time, the fourth motor 34 rotates, and the cutter 32 moves to the heat shrink tube by pushing the movable block 30, and cuts off the heat shrink tube.

[0074] Afterwards, the fifth motor 35 drives the moving plate 28 to rotate until the heat shrink tube is aligned with the battery aluminum shell 13. At the same time, the fourth motor 34 drives the moving block 30 to reset the cutter 32. At this time, the second height adjustment member drives the sliding seat 44 to move downward, so that the heat shrink tube is sleeved on the battery aluminum shell 13, completing the pre-sleeving of the heat shrink tube.

[0075] As a further optimization scheme, two sets of clamping mechanisms (not shown in the figure) are arranged in the rear bracket 14, and the two sets of clamping mechanisms are respectively arranged at appropriate positions above the movable plate 28 and at appropriate positions below the cutter 32. After the end of the heat shrink tube extends into the tapered hole 29, the two clamping assemblies clamp the heat shrink tube, and then the cutter 32 performs the cutting work, which can improve the cutting efficiency. The clamping mechanism is a conventional device in the field, and its specific structure will not be described in detail.

[0076] In a further optimized solution, a feeding belt 19 and a feeding belt 20 are further provided on the base 1. The feeding belt 19 is provided on a side of the conveyor belt assembly 2 close to the front bracket 3, and the feeding belt 20 is provided on a side of the conveyor belt assembly 2 close to the rear bracket 14;

[0077] A material moving assembly 11 is respectively arranged between the upper material belt 19 and the conveyor belt assembly 2, between the lower material belt 20 and the conveyor belt assembly 2, and on the top of the conveyor belt assembly 2. The material moving assembly 11 arranged corresponding to the upper material belt 19 is used to place the battery aluminum shell 13 to be processed on the upper material belt 19 into the placement hole 39, and the material moving assembly 11 arranged corresponding to the lower material belt 20 is used to place the processed battery aluminum shell 13 in the placement hole 39 onto the lower material belt 20. The material moving assembly 11 located at the top of the conveyor belt assembly 2 is used to move the battery aluminum shell 13 from the placement seat 12 close to the front bracket 3 to the placement seat 12 close to the rear bracket 14.

[0078] like Figure 1As shown, as the conveyor belt assembly 2 rotates, the top of the placement seat 12 on the right side rotates to the left side, and the original top will be facing down at the bottom, and the battery aluminum shell 13 will fall. Therefore, when the conveyor belt assembly 2 rotates step by step to a placement seat 12 at the highest position of the vertical section, the material transfer assembly 11 on the conveyor belt assembly 2 can move the battery aluminum shell 13 from the right side to the left side, and place it in the placement hole 39 at the top of the left placement seat 12, so as to realize the transfer of the battery aluminum shell 13.

[0079] A further optimized solution is that the material moving assembly 11 located at the top of the conveyor belt assembly 2 includes a support 21 fixedly connected to the side wall of the conveyor belt assembly 2, one end of a rocker arm 22 is hinged in the support 21, a first motor 23 is transmission-connected between the rocker arm 22 and the support 21, the other end of the rocker arm 22 is fixedly connected to a fixed clamp 24, the other end of the rocker arm 22 is also slidably connected to a movable clamp 27, the movable clamp 27 and the fixed clamp 24 are used to clamp the battery aluminum shell 13, a first screw rod 26 is rotatably connected in the rocker arm 22, the first screw rod 26 is transmission-connected to the movable clamp 27, and one end of the first screw rod 26 is transmission-connected to the second motor 25.

[0080] like Figure 1 and Figure 3 As shown, the rocker arm 22 moves to the right side driven by the first motor 23, so that the fixed clamp 24 corresponds to the side wall of the battery aluminum shell 13. Then, the second motor 25 rotates to drive the first screw rod 26 to rotate, and drives the movable clamp 27 to move toward the direction of the battery aluminum shell 13 through threaded transmission to clamp the battery aluminum shell 13. Then, the first motor 23 drives the rocker arm 22 to rotate 180 degrees counterclockwise, and places the battery aluminum shell 13 in the placement hole at the top of the placement seat 12 on the left, thereby realizing the transfer of the battery aluminum shell 13.

[0081] For further optimization, the spacing between two adjacent placement seats 12 must be satisfied that when the placement seat 12 on the right side of the conveyor belt assembly 2 is at the highest point of the vertical end, the placement seat 12 on the left side of the conveyor belt assembly 2 is also at the highest point of the vertical end.

[0082] According to a further optimization scheme, the position of the conical hole 29 corresponding to the top of the movable disk 28 may also be provided with a fixed clamp block 24 and a movable clamp block 27 according to the structure of the material transfer assembly 11. The heat shrink tube is clamped by the fixed clamp block 24 and the movable clamp block 27. After the heat shrink tube is put on the battery aluminum shell 13, the heat shrink tube can be released through the opened movable clamp block 27.

[0083] According to a further optimized solution, the heat drying assembly includes a plurality of heat drying guns 17 fixedly connected to the rear bracket 14 , and the plurality of heat drying guns 17 are sequentially arranged below the sliding seat 44 from top to bottom.

[0084] like Figure 1As shown, the main function of the heat drying gun 17 is to dry the heat shrink tube so that it can be fixedly sleeved on the battery aluminum shell 13. Arranging a plurality of heat drying guns 17 can make multiple heat drying guns work alternately, thereby improving the operation stability of the equipment.

[0085] According to a further optimized solution, the first height adjustment member includes a third screw rod 40 vertically rotatably connected to the moving rod 9, the second cylinder 10 is threadedly sleeved on the third screw rod 40 through a connecting block 42, and one end of the third screw rod 40 is transmission-connected to a seventh motor 41.

[0086] like Figure 6 As shown, the seventh motor 41 rotates to drive the third screw rod 40 to rotate, and the third screw rod 40 drives the connecting block 42 to move up and down through thread transmission, thereby realizing the up and down movement of the second cylinder 10.

[0087] According to a further optimized solution, the second height adjustment member includes a rack 36 fixedly connected to the side wall of the sliding seat 44 , a sixth motor 38 is fixedly connected to the rear bracket 14 , and an output shaft of the sixth motor 38 is fixedly sleeved with a gear 37 , which meshes with the rack 36 .

[0088] like Figure 2 As shown, the sixth motor 38 rotates to drive the gear 37 to rotate. When the gear 37 rotates, it drives the rack 36 to move through the meshing of the gear teeth. By controlling the rotation direction of the sixth motor 38, the up and down movement of the rack 36 is controlled, thereby achieving height control of the movable plate 28.
