[0002] Cell packaging is a key process in the manufacturing process of lithium batteries. Cell leakage will not only make the product scrapped, but also pollute the equipment. Reducing the proportion of this defect has an important impact on stabilizing the quality of the cell.

[0003] In the prior art, many important processes are involved in battery cell packaging, which usually include: aluminum-plastic film shell loading, battery cell loading and positioning, battery cell shelling, aluminum-plastic film folding, battery cell top and side sealing and other processes. Most of the current companies carry out battery cell packaging in the form of a single-line assembly line, which not only consumes a lot of manpower and material resources, but also has low production efficiency, occupies a large space and has low utilization rate. In addition, most lithium battery packaging production lines need to manually complete the aluminum-plastic film folding process before the battery cell top and side sealing process. The manual folding method consumes a lot of manpower and affects production efficiency. Alternatively, a folding equipment station is set up separately, and the aluminum-plastic film and battery cell in the jig are taken out and folded in the folding mechanism, and then transferred back to the jig for subsequent processes. This method consumes a lot of material resources, occupies a large space and is cumbersome to operate, affecting production efficiency, and needs to be solved urgently. Utility Model Content

At the same time, the folding process of the aluminum-plastic film can be completed during the cyclic transportation of the work station fixture, without occupying additional equipment stations, thus saving space.

[0005] The above invention objectives of the present application are achieved through the following technical solutions:

At the same time, by setting a overlapping platform on the first linear module and the second linear module, it can play a connecting role in facilitating the transfer of the work station fixtures between various tracks.

[0019] In a preferred example, the present application can be further configured as follows: the top sealing device and the side sealing device are sequentially arranged on one side of the third linear module, and a detection mechanism is arranged at one end of the first linear module close to the third linear module, and when the overlapping platform drives the work station fixture to move to one end of the first linear module close to the third linear module, the detection mechanism is used to detect the folding alignment of the aluminum-plastic film shell.

The mounting plate J3 and the folding plate J4 are both provided with an adapting groove J6 that is adapted to the pit position of the aluminum-plastic film J5. When the folding plate J4 is fitted to the mounting plate J3, a matching groove J6 is formed between the two adapting grooves J6. The outer side of the circulating conveyor line J1 is provided with a feeding device J8, a top sealing device J9, a side sealing device J10 and a feeding device (not shown in the figure) in sequence along the conveying direction. The feeding device J8 is used to convey the aluminum-plastic film J5 shell and the battery cell J7 to the work station fixture J2. The top sealing device J9 and the side sealing device J10 are used to perform top sealing and side sealing processes on the aluminum-plastic film J5 shell respectively. The feeding device is used to feed the packaged battery cell J7.

Compared with the single-line assembly line, the structural design is more compact and reasonable and can reduce the occupied space. The station fixture J2 automatically completes the reset after passing through the processes of loading, top sealing, side sealing and unloading in sequence, so as to improve the efficiency of the battery cell J7 packaging. In addition, by arranging a folding device on the station fixture J2 and arranging two sets of driving devices J16 in the circular conveyor line J1, after the circular conveyor line J1 drives the station fixture J2 to move to the loading device J8 for loading, one of them The group drive device J16 can then drive the folding plate J4 on the work station fixture J2 to rotate until the mounting plate J3 and the folding plate J4 are fitted together to complete the folding of the aluminum-plastic film J5, which is convenient for the subsequent top sealing and side sealing processes. Before the circulating conveyor line J1 drives the work station fixture J2 to move to the unloading device for unloading, another group drive device J16 can open the folding plate J4 to facilitate the unloading device to take out the packaged battery cell J7. Compared with setting up a folding device separately on the production line, the work station fixture J2 can complete the folding process of the aluminum-plastic film J5 during the circulating conveying process, and there is no need to occupy additional equipment stations, saving space, and the structural design is reasonable and compact.

[0035] It should be noted that the specific structures and principles of the feeding device J8, the top sealing device J9, the side sealing device J10 and the unloading device are common knowledge to those skilled in the art, and corresponding conventional equipment can be selected, which will not be elaborated here.

[0036] like Figure 3 As shown, in order to realize the driving of the folding plate J4 to rotate, the station fixture J2 is rotatably installed with a rotating rod J17, the folding plate J4 is fixedly connected to the rotating rod J17, the rotating rod J17 is coaxially fixedly connected with a gear J18, the station fixture J2 is slidably provided with a rack J19, the rack J19 is meshed with the gear J18, the rack J19 is provided with a positioning member J20, the positioning member J20 is provided with a positioning groove J21, the driving device J16 includes a double-axis moving component J161 and a driving device J16 connected to the double-axis moving component J161.

When the alignment column J162 is plugged into the alignment slot J21, the double-axis moving assembly J161 is used to drive the alignment column J162 to move along the sliding direction of the rack J19. When the work station fixture J2 moves to the loading device J8 or the unloading device, the alignment column is driven by the double-axis moving assembly J161. J162 performs biaxial movement, and can simultaneously complete the plug-in cooperation between the alignment column J162 and the alignment groove J21, and enable the alignment column J162 to drive the rack J19 to slide on the work station fixture J2, so that the rotating rod J17 drives the folding plate J4 to rotate under the transmission action of the gear J18 and the rack J19, until it is fitted to the mounting plate J3 to complete the folding process of the aluminum-plastic film J5 or open the folding plate J4, so as to facilitate the subsequent unloading device to take out the packaged battery cell J7, and the structure is compact and practical.

At this time, the air pump J24 is started to vacuum the air pump J24 through the first air hole J22 and the air channel, so that the second air hole J23 continuously produces an adsorption effect on the aluminum-plastic film J5 shell on the folding plate J4, so that the aluminum-plastic film J5 shell can always fit with the folding plate J4 during the folding process, so as to prevent the aluminum-plastic film J5 shell from being separated from the folding plate J4 due to its own gravity, so as to enhance the folding effect of the aluminum-plastic film J5 shell.

[0039] It should be noted that the hanging position of the tension spring J27 is related to the position of the connector J26. The staff can adjust the hanging position of the tension spring J27 according to the actual installation position of the connector J26, so that the tension spring J27 can continuously provide the connector J26 with force to rotate the folding plate J4 close to the mounting plate J3.

The first linear module J11 and the second linear module J12 are both slidably provided with a lap platform J15. The two lap platforms J15 are both slidably matched with the station fixture J2. When the lap platform J15 slides to one end of the first linear module J11 close to the third linear module J13 or one end of the second linear module J12 close to the third linear module J13, the lap platform J15 is connected Through the third linear module J13, when the overlapping platform J15 slides to one end of the first linear module J11 close to the fourth linear module J14 or one end of the second linear module J12 close to the fourth linear module J14, the overlapping platform J15 is connected to the fourth linear module J14, and by setting the first linear module J11, the second linear module J12, the third linear module J13 and the fourth linear module J14, a U-shaped circular conveying route can be performed for the work station fixture J2, and at the same time, by setting the overlapping platform J15 on the first linear module J11 and the second linear module J12, it can play a connecting role in facilitating the transfer of the work station fixture J2 between various tracks.
