Description

Technical Field

[0001] This utility model relates to an automatic feeding device for a battery assembly line. Background Technology

[0002] Some rechargeable batteries use a pouch lithium battery encapsulated in a casing. During production, these pouch batteries are typically transported to the assembly station and automatically assembled into the casing via an assembly line. During feeding, multiple pouch batteries are loaded onto a pallet; during loading, clamps are used to move the pouch batteries one by one onto the conveyor belt of the assembly line. Because the pallets are large, the battery clamps are unsuitable, and empty pallets must be manually removed, making the operation cumbersome and inefficient. Utility Model Content

[0020] The following description, in conjunction with the accompanying drawings, further illustrates the proposed solution:

[0021] See appendix Figure 1-17 An automatic feeding device for a battery assembly line includes an assembly conveyor belt 2, a feeding mechanism 1, a lifting mechanism 3, a feeding conveyor belt 4, and a recycling conveyor belt 5.

[0022] The feeding mechanism 1 includes a suction mechanism 10 and a linear sliding module 16; the suction mechanism 10 is mounted on the linear sliding module 16 and is driven by the linear sliding module 16 to slide laterally; the linear sliding module 16 includes a slide rail 161 and a slide table 162 slidably mounted on the slide rail 161. The slide rail 161 is arranged on two columns 163 and is in the shape of a gantry.

[0023] Below the suction mechanism 10, along the sliding direction of the suction mechanism 10, there are sequentially arranged a feeding station 200, a loading station 100, and a recycling station 300.

[0024] The feeding station 200 is used to place battery materials 6, which includes a tray 62 and a plurality of soft-pack batteries 61 loaded on the tray 62.

[0025] The loading station 100 is located at the input end of the assembly conveyor belt 2, which is used to transport batteries to the assembly station.

[0026] The feeding mechanism 1 includes a first working state of moving the pouch battery 61 from the feeding station 200 to the feeding station 100 and a second working state of moving the tray 62 from the feeding station 200 to the recycling station 300. The suction mechanism 10 includes a fixed frame 11 and a first suction component 12 and a second suction component 13 that are vertically and vertically mounted on the fixed frame 11. When the feeding mechanism 1 is in the first working state, the first suction component 12 rises and falls independently to pick up and release the pouch battery 61; when the feeding mechanism 1 is in the second working state, the first suction component 12 and the second suction component 13 rise and fall synchronously to pick up and release the tray 62.

[0027] The automatic feeding device for the battery assembly line of this technical solution allows both the soft-pack battery 61 and the tray 62 to be transported by the feeding mechanism 1. The first suction component 12 of the feeding mechanism 1 can be used alone or in conjunction with the second suction component 13 to meet the handling requirements of the soft-pack battery 61 and the tray 62 and improve production efficiency.

[0028] The material suction mechanism 10 further includes a first cylinder 14 for driving the first material suction assembly 12 to rise and fall, and a second cylinder 15 for driving the second material suction assembly 13 to rise and fall. The first material suction assembly 12 includes a first bracket 122 and a plurality of first suction nozzles 121 mounted on the first bracket 122; the cylinder body of the first cylinder 14 is fixed to a fixed frame 11, and the telescopic rod of the first cylinder 14 is fixedly connected to the first bracket 122. The second material suction assembly 13 includes a second bracket 132 and a plurality of second suction nozzles 131 mounted on the second bracket 132; the cylinder body of the second cylinder 15 is fixed to the fixed frame 11, and the telescopic rod of the second cylinder 15 is fixedly connected to the second bracket 132. When the feeding mechanism 1 is in the second working state, the first cylinder 14 and the second cylinder 15 are linked; the first suction nozzle 121 and the second suction nozzle 131 are respectively connected to an adsorption negative pressure generator (not shown in the attached figure), and the adsorption negative pressure generator is configured to generate suction force for the first suction nozzle 121 and the second suction nozzle 131 to adsorb battery material 6.

[0029] The first suction nozzle 121 and the second suction nozzle 131 of this technical solution are driven by the first cylinder 14 and the second cylinder 15 respectively. The structure is compact, the layout is reasonable, and it is easy to implement.

[0030] Both the first suction nozzle 121 and the second suction nozzle 131 include a mouth part 111, a tube part 112, a limiting part 113, and a spring 114. The limiting part 113 is fixed to the upper end of the tube part 112, the mouth part 111 is located at the lower end of the tube part 112, and the spring 114 is sleeved on the tube part 112. Both the first support 122 and the second support 132 include a support rod 110. The tube part 112 is movably inserted into the support rod 110. One end of the spring 114 abuts against the bottom side of the support rod 110, the other end of the spring 114 abuts against the mouth part 111, and the limiting part 113 abuts against the top side of the support rod 110. The support rod 110 has a through hole 1101 for the tube part 112 to pass through. In this embodiment, the limiting part 113 is screwed to the upper end of the tube part 112.

[0031] The first suction nozzle 121 and the second suction nozzle 131 of this technical solution adopt an elastic telescopic structure, which has a buffering effect when adsorbing materials, and can prevent excessive contact with battery materials 6 during adsorption, thereby preventing damage to the soft-pack battery 61 or the suction nozzle.

[0032] The feeding conveyor belt is used to transport stacked battery materials 6; the output end of the feeding conveyor belt 4 is located below the feeding station 200; the lifting mechanism 3 is located at the output end of the feeding conveyor belt 4 to lift the stacked battery materials 6 to the feeding station 200. The stacked battery materials 6 are lifted to the feeding station 200 step by step by the lifting mechanism 3, which can save space and eliminates the need to lay them flat on the conveyor belt in layers.

[0033] The lifting mechanism 3 includes a fork 31 and a screw lifting mechanism 32; the fork 31 is mounted on the screw lifting mechanism 32 and is driven up and down by the screw lifting mechanism 32; the fork 31 is provided with an opening 312 that allows the feeding conveyor belt 4 to pass through, so that when the fork 31 descends, it can pass over the feeding conveyor belt 4, thereby allowing the battery material 6 on the feeding conveyor belt 4 to move above the fork 31, and the battery material 6 can be lifted when the fork 31 moves upward.

[0034] The forklift 31 is driven by the screw lifting mechanism 32, which can lift materials step by step.

[0035] In this embodiment, the feeding conveyor belt 4 includes two belts, which are spaced apart; the fork 31 includes three evenly spaced fork plates 311, and the space between adjacent fork plates 311 forms the clearance opening 312.

[0036] The lead screw lifting mechanism 32 includes a frame 321 and a lead screw 322 and a motor 323 mounted on the frame 321. The lead screw 322 is rotatably mounted on the frame 321. The frame 321 includes a guide post 3211 parallel to the lead screw 322. One end of the fork 31 is sleeved on the guide post 3211 and the lead screw 322 and is threadedly engaged with the lead screw 322. The output end of the motor 323 is connected to the lead screw 322 through a gear transmission structure 324 to drive the lead screw 322 to rotate.

[0037] The recycling conveyor belt 5 is used to receive and transport the pallet 62; the recycling station 300 is located at the input end of the recycling conveyor belt 5.

[0038] The assembly conveyor belt 2, the feeding conveyor belt 4, and the recycling conveyor belt 5 are mounted on their respective support frames (not shown in the attached drawings).

[0039] The pouch batteries 61 are arranged in a matrix within the corresponding recesses of the tray 62, in this embodiment, a 3-row x 4-column arrangement. The sliding direction of the suction mechanism 10 corresponds to the row direction of the pouch batteries 61, and the assembly conveyor belt 2 extends along the column direction of the pouch batteries 61. The first suction nozzles 121 are divided into four groups corresponding to the column number of the pouch batteries 61, with two first suction nozzles 121 in each group, and the four groups of first suction nozzles 121 are respectively mounted on four support rods. That is, the first suction assembly 12 can absorb one row of pouch batteries 61 at a time. The second suction nozzles 131 are divided into at least two groups, with each group of second suction nozzles 131 spaced apart along the row direction of the pouch batteries 61.

[0040] When the feeding mechanism 1 is in the second working state, the first suction nozzle 121 and the second suction nozzle 131 are configured to perform suction action at the feeding station 200, and the first cylinder 14 and the second cylinder 15 are configured to move upward and perform repeated extension and retraction activities after the first suction nozzle 121 and the second suction nozzle 131 perform suction action, so as to achieve the effect of vibrating the tray 62 and prevent the tray 62 from sticking to the soft-pack battery 61 underneath.

[0041] The workflow of this technical solution is as follows:

[0042] 1. Place the stacked battery material 6 on the feeding conveyor belt 4 and let it be conveyed to the lifting mechanism 3, where it is lifted by the fork 31 to the feeding station 200.

[0043] 2. The feeding mechanism 1 is in its first working state: the suction mechanism 10, driven by the linear sliding module 16, moves above the feeding station 200. The first cylinder 14 drives the first suction component 12 to descend until it contacts the first suction nozzle 121, adsorbing the soft-pack battery 61. Figure 1As shown; the first suction nozzle 121 rises to separate the pouch battery 61 from the tray 62; the suction mechanism 10 slides above the loading station 100, the first suction assembly 12 descends and releases the pouch battery 61, as... Figure 15 As shown; repeat the operation until the pouch battery 61 on tray 62 has been moved.

[0044] 3. The feeding mechanism 1 switches to the second working state: Driven by the linear sliding module 16, the suction mechanism 10 moves above the feeding station 200. The first cylinder 14 and the second cylinder 15 descend synchronously, causing the first suction nozzle 121 and the second suction nozzle 131 to contact the tray 62 and suction the tray 62. Figure 16 As shown; after adsorbing the tray 62, the first cylinder 14 and the second cylinder 15 drive the first suction nozzle 121 and the second suction nozzle 131 to move upward. Then, the first cylinder 14 and the second cylinder 15 perform multiple short-stroke repeated extension and retraction movements to achieve a vibration effect, so that the tray 62 is fully separated from the tray 62 below it and does not stick to the soft-pack battery 61. After that, the suction mechanism 10 slides to the top of the recycling station 300 and lowers the tray 62.

[0045] 4. The lifting mechanism 3 lifts the lower battery material 6 to the feeding station 200, and the feeding mechanism 1 repeats the above operation.

[0046] The above preferred embodiments should be regarded as illustrative examples of the embodiments of the present application. Any technical deductions, substitutions, improvements, etc. that are similar to or based on the present application should be considered within the scope of protection of this patent.
