Specifically, the feeding module 20 includes a first linear module 210 and an installation station 220. The installation station 220 is arranged on the first linear module 210. The first linear module 210 is arranged on the workbench 10 and is used to drive the installation station 220 to reciprocate along a first direction. The staff places the battery cell 80 to be processed on the installation station 220 so that the side sealing edge 810 of the battery cell 80 is parallel to the first direction. Under the action of the first linear module 210, the battery cell 80 moves along the first direction to a position corresponding to the glue dispensing mechanism, and the glue dispensing mechanism distributed on both sides of the first linear module 210 is automatically pressed. The module 30 can be moved to the glue dispensing position 811 of the battery cell 80 for glue dispensing under the drive of the linear motion module 310. After the glue dispensing work is completed, under the action of the first linear module 210, the battery cell 80 continues to move along the first direction to the position corresponding to the folding mechanism. The folding modules 40 distributed on both sides of the first linear module 210 include a second linear module 410 and a folding assembly 420 arranged on the second linear module 410. The folding assembly 420 changes the edge sealing 810 on both sides of the battery cell 80 from a horizontal state to a vertical state along the second direction under the drive of the second linear module 410.

[0021] The first linear module 210 of this embodiment adopts existing devices and can be a lead screw type linear module, which has the advantages of stable operation, fast response and high precision, etc., which is not specifically limited here.

[0022] In this embodiment, the staff only needs to place the battery cell 80 on the installation station 220 , and no human hands will touch the battery cell 80 again during the gluing and folding process, thereby improving the control of the appearance quality of the battery cell 80 .

[0024] As a preferred solution of this embodiment, refer to Figure 2 and Figure 7 The installation station 220 includes a first base 221 and a first vacuum suction cup 222. The first base 221 is arranged on the first linear module 210. A mounting slot 2201 is formed on the first base 221. The first vacuum suction cup 222 is arranged in the mounting slot 2201. The mounting slot 2201 is also connected to an external negative pressure device (not shown in the figure) through a first air pipe (not shown in the figure).

[0025] Among them, the installation station 220 of this embodiment is composed of a first base 221 and a first vacuum suction cup 222. The first base 221 is arranged on the first linear module 210, and reciprocates along the first direction under the action of the first linear module 210. The installation slot 2201 formed on the first base 221 provides an installation environment for the first vacuum suction cup 222 to be set on the first base 221, so that the first vacuum suction cup 222 is fixed on the first base 221. During use, the battery cell 80 is set on the first vacuum suction cup 222, and the installation slot 2201 is connected to the external negative pressure equipment through the first air pipe. Under the action of the external negative pressure equipment, the battery cell 80 is stably adsorbed on the first vacuum suction cup 222, so as to prepare for the subsequent dispensing and folding processes. This method of adsorbing the battery cell 80 through negative pressure will not cause damage to the surface of the battery cell 80, thereby ensuring the yield of the battery cell 80; the negative pressure adsorption method is suitable for battery cells 80 of different shapes and sizes, so as to improve the applicability of the dispensing and folding equipment of this embodiment; the negative pressure equipment is usually easy to operate, and the fixing and disassembly process is fast, thereby improving the processing efficiency of the battery cell 80.

[0026] Of course, in order to improve the working efficiency of the dispensing and folding process, a plurality of first vacuum suction cups 222 can be arranged on the first base 221 along the first direction, and each first vacuum suction cup 222 is provided with a battery cell 80. When dispensing, the hot melt glue machine 320 can dispense glue to the side edge 810 of each battery cell 80 under the action of the first linear module 210, thereby improving the dispensing efficiency. Figure 2 shows an example in which three battery cells 80 are arranged on the first base 221, wherein each battery cell 80 is fixed by two first vacuum suction cups 222, thereby improving the stability of the arrangement of the battery cell 80.

[0027] As a preferred solution of this embodiment, refer to Figure 1 and Figure 3 The linear motion module 310 includes a third linear module 311 and a fourth linear module 312 arranged on the third linear module 311. The hot melt glue machine 320 is arranged on the fourth linear module 312. The third linear module 311 is arranged on the workbench 10, and is used to drive the hot melt glue machine 320 to reciprocate along the second direction. The fourth linear module 312 is used to drive the hot melt glue machine 320 to reciprocate along the vertical direction; the hot melt glue machine 320 includes a material tank 321, a material pipe 322, a glue dispensing nozzle 323 and a solenoid valve 324. The material tank 321 is arranged on the fourth linear module 312. One end of the material pipe 322 is connected to the material tank 321, and the other end is connected to the glue dispensing nozzle 323. The solenoid valve 324 is arranged on the glue dispensing nozzle 323, and is used to control the glue dispensing nozzle 323 to dispense glue to the glue dispensing position 811 of the battery cell 80.

[0028] In the actual working process, the battery core 80 is fixed on the first vacuum suction cup 222, and the first linear module 210 works to transport the battery core 80 to between the two dispensing modules 30 for dispensing.

[0029] Specifically, the linear motion module 310 is composed of a third linear module 311 and a fourth linear module 312, and the two cooperate to adjust the position of the hot melt glue machine 320 in the vertical direction and the second direction, so that the hot melt glue machine 320 can reach the glue dispensing position 811 of the battery cell 80, and perform glue dispensing on battery cells 80 of different sizes, thereby improving the practicality of the glue dispensing and folding equipment of this embodiment; the hot melt glue machine 320 of this embodiment is composed of a material tank 321, a material pipe 322, a glue dispensing nozzle 323 and a solenoid valve 324. The material tank 321 is used to store hot melt glue. During use, a heating rod is provided in the material tank 321, which is used to heat the hot melt glue to a melted fluid state. Under the control of the solenoid valve 324, the melted hot melt glue is transported along the material pipe 322 to the glue dispensing nozzle 323, flows out along the glue dispensing nozzle 323, and adheres to the glue dispensing position 811 of the battery cell 80, thereby achieving the purpose of glue dispensing the side sealing edge 810 of the battery cell 80. The hot melt adhesive machine 320 of this embodiment has a controllable usage amount of hot melt adhesive, which reduces waste; at the same time, its efficient production capacity also reduces labor and time costs, and improves the dispensing efficiency of the battery cell 80.

[0030] The third linear module 311 and the fourth linear module 312 of this embodiment can be linear motor type linear modules, which have the advantages of simple structure, fast response and high precision, etc., which are not specifically limited here.

One end of the driving cylinder 421 is arranged at the end of the mounting plate 423 away from the first linear module 210. The driving end of the driving cylinder 421 is connected to the flipping assembly 422. The flipping assembly 422 is rotatably arranged between the two first mounting frames 424. The driving cylinder 421 is used to push the flipping assembly 422 from a horizontal state to a vertical state, thereby driving the side edge sealing 810 of the battery cell 80 to change from a horizontal state to a vertical state; wherein the height of the driving end of the driving cylinder 421 is higher than the end connected to the mounting plate 423.

[0032] In the actual working process, after the glue dispensing work is completed, the first linear module 210 works to transport the battery cell 80 to between the two folding modules 40 for folding work.

[0033] Specifically, the folding assembly 420 is composed of a driving cylinder 421, a flip assembly 422, a mounting plate 423 and two first mounting frames 424. The mounting plate 423 is arranged on the second linear module 410, and the two first mounting frames 424 are arranged on the mounting plate 423 to provide an installation environment for the setting of the flip assembly 422. More specifically, the flip assembly 422 is rotatably arranged between the two first mounting frames 424. Before the battery cell 80 is folded, the flip assembly 422 is in a horizontal state. The module 410 drives the mounting plate 423 to reciprocate along the second direction, so that the side sealing edges 810 on both sides of the battery cell 80 are respectively located on the flipping components 422 of the two dispensing modules 30. Under the action of the driving cylinder 421, the flipping component 422 can be flipped upward 90° from the horizontal state to the vertical state, thereby driving the side sealing edge 810 of the battery cell 80 to change from the horizontal state to the vertical state, and under the action of the hot melt adhesive, the side sealing edge 810 is attached to the battery cell 80 body, completing the folding work of the battery cell 80. The folded side sealing edge 810 is flush with the thickness direction of the battery cell 80.

[0034] The second linear module 410 of this embodiment may be a linear motor type linear module, which has the advantages of simple structure, fast response and high precision, and is not specifically limited here. Figure 4 The driving motor of the second linear module 410 is not shown.

[0035] As a preferred solution of this embodiment, refer to Figure 1 , Figure 4 and Figure 5 , fixing holes (not shown in the figure) are formed on the two first mounting frames 424; the flip assembly 422 includes a mounting shaft 4221 and a rotating block 4222, both ends of the mounting shaft 4221 are inserted into the fixing holes, the rotating block 4222 is rotatably sleeved on the mounting shaft 4221, and the side of the rotating block 4222 away from the first linear module 210 is connected to the driving end of the driving cylinder 421; horizontal limit grooves 4241 are formed on the two first mounting frames 424, and the rotating block 4222 is located in the horizontal limit grooves 4241.

[0036] The flip assembly 422 is composed of a mounting shaft 4221 and a rotating block 4222. The two ends of the mounting shaft 4221 are fixed on the two first mounting frames 424 by inserting into the fixing holes on the first mounting frames 424. The rotating block 4222 is formed with an avoidance hole 4223. The rotating block 4222 is rotatably sleeved on the mounting shaft 4221 through the avoidance hole 4223. The rotating block 4222 is connected to the driving end of the driving cylinder 421. In actual use, the rotating block 4222 is in a horizontal state before the folding process is performed. When the side edge seal 810 of the battery cell 80 is moved to the folding station, it is flatly laid on the rotating block 4222. Under the action of the driving cylinder 421, the rotating block 4222 is flipped from a horizontal position to a vertical state, so that the side edge seal 810 of the battery cell 80 is transformed from a horizontal state to a vertical state, and the folding work of the battery cell 80 is completed. The horizontal limit groove 4241 is set to enable the rotating block 4222 to be in an initial state before the folding work, so that under the action of the second linear module 410, after the dispensing module 30 approaches the installation station 220, the side sealing edge 810 of the battery cell 80 can be flatly laid on the rotating block 4222 to improve the folding work efficiency.

[0038] Among them, the first slide rail 412 on the connecting plate 411 is slidably connected to the first slider 4231 on the mounting plate 423. When processing battery cells 80 of different specifications, the dispensing and folding equipment of this embodiment can adjust the position of the mounting plate 423 according to the width of the battery cell 80 to improve the applicability of the dispensing and folding equipment. After adaptively adjusting the position of the mounting plate 423, fasteners are set on the strip holes 4232 set on the mounting plate 423 to fix the mounting plate 423 to the connecting plate 411, so that the second linear module 410 drives the connecting plate 411 and the mounting plate 423 to move together.

[0039] Therefore, before using the dispensing and folding equipment of this embodiment, the position of the mounting plate 423 can be adjusted according to the specifications of the battery cell 80 to improve the applicability of the dispensing and folding equipment.

The driving end of the driving member 520 is connected to the fixed pressure plate 530, thereby driving the fixed pressure plate 530 to move in the vertical direction, so as to drive the fixed pressure plate 530 to press the battery cell 80 and fix the battery cell 80. In this embodiment, multiple battery cells 80 can be fixed simultaneously on the first base 221 along the first direction. The fixed pressure plate 530 is a rectangular structure, and its structural size corresponds to the battery cell 80, so that multiple battery cells 80 can be fixed simultaneously.

[0043] Of course, after the folding work is completed, the driving member 520 drives the fixed pressing plate 530 to move away from the battery cell 80, and the fixed pressing plate 530 releases the pressure on the battery cell 80. The driving member 520 adopts the existing driver 630, for example, the driving member 520 can be a driving cylinder 421, which is not specifically limited here.

A second slide rail 611 is arranged on the support table 610 along the second direction. A second slider 621 is arranged on the side of the alignment plate 620 close to the support table 610. The second slide rail 611 is slidably connected to the second slider 621. The driver 630 is located on the side of the support table 610 away from the first linear module 210. The driver 630 is used to drive the alignment plate 620 to move along the second direction so that the two alignment plates 620 cooperate to correct the battery cell 80 along the first direction.

[0045] In actual application, the staff places the battery cell 80 on the first vacuum suction cup 222 at the loading station. Manual placement of the battery cell 80 will cause a certain deviation in the position of the battery cell 80. By setting the alignment components 60 on both sides of the first linear module 210, the alignment components 60 are composed of a support platform 610, an alignment plate 620 and a driver 630. The second slider 621 of the alignment plate 620 is connected to the second slide rail 611 on the support platform 610 in a sliding manner in the second direction, and under the action of the driver 630, the alignment plate 620 is driven to move in the second direction, so that the two alignment plates 620 correct the battery cell 80 along the first direction, thereby improving the processing efficiency of the dispensing and folding equipment on the battery cell 80, and ensuring the yield rate of the battery cell 80. The above-mentioned driver 630 adopts an existing driving device, for example, the driver 630 can be a driving cylinder 421, which is not specifically limited here.

[0047] Among them, after the battery cell 80 is glued and folded, under the action of the first linear module 210, the installation station 220 continues to move along the first direction and reaches the unloading module 70. At this time, the external negative pressure device that controls the first vacuum suction cup 222 is closed, and the unloading module 70 is used to remove the battery cell 80 on the installation station 220 from the installation station 220 and transfer it to the next processing step equipment or the receiving area; specifically, the unloading module 70 is composed of a fifth linear module 710, a sixth linear module 720 and a manipulator 730. The fifth linear module 710 and the sixth linear module 720 respectively adjust the position of the manipulator 730 along the first direction and the vertical direction, so that the manipulator 730 can accurately move to the installation station 220 to grab the battery cell 80 on the installation station 220.

[0048] The setting of the above-mentioned unloading module 70 can quickly remove the battery cell 80 from the installation station 220. Under the action of the first linear module 210, the installation station 220 returns to the loading station along the first direction, and the above-mentioned feeding action is cycled to realize the assembly line processing of the battery cell 80.

[0051] The manipulator 730 is composed of a second base 731 and a second vacuum suction cup 732. The second base 731 is arranged on the second mounting frame 721 on the sixth linear module 720. The mounting hole 7311 formed on the second base 731 provides an installation environment for the second vacuum suction cup 732 to be arranged on the second base 731, so that the second vacuum suction cup 732 is fixed on the second base 731. During use, the adsorption force between the battery cell 80 and the first base 221 is cancelled, and the second vacuum suction cup 732 is adjusted to be located on the top of the battery cell 80 and in contact with the battery cell 80. The mounting hole 7311 is connected to the external negative pressure device through the air pipe. Under the action of the external negative pressure device, the battery cell 80 is stably adsorbed on the second vacuum suction cup 732, and the battery cell 80 is taken away under the action of the fifth linear module 710 and the sixth linear module 720, and transferred to the next processing process equipment or the material receiving area. The external negative pressure device controlling the second vacuum suction cup 732 is closed, and the battery cell 80 falls off from the second vacuum suction cup 732. Complete the gluing and folding work of battery cell 80.

[0052] Of course, in this embodiment, a plurality of second bases 731 may be disposed on the second mounting frame 721 at the same time.
