[0040] The positioning mechanism 100 is installed in the frame 10 and includes a driver, a turntable 101, a fixture, a fixture drive, an air knife, and a fixed plate 110; the driver includes a splitter 150 and a motor 151, among which the turntable 101 and the output shaft of the splitter 150 It is connected and can be driven by a motor 151; the fixtures are distributed on the rotating axis of the turntable 101 at equal angles, and the number is equal to the number of divisions in the circumference of the divider 150; the fixture includes a fixed plate 102 and a pressure plate 103, a fixed plate 102 and a pressure plate 103 is connected by hinge 104, fixed plate 102 is fixed on turntable 101; the fixture drive includes A cylinder 111, B cylinder 130 and C cylinder 131. The vertical B cylinder 130 and the horizontal C cylinder 131 are connected to form a closed drive, corresponding to The feeding mechanism 200 is installed on the fixed plate 110 to drive the pressing plate 103 to turn and close; the A cylinder 111 is installed on the fixed plate 110 corresponding to the discharging mechanism to open the pressing plate 103; the air knife includes A nozzle 140 and B nozzle 160 , B tuyere 160 is installed on the fixed plate 110 corresponding to the feeding mechanism. When the pressing plate 103 is closed, the ion wind is blown out to the diaphragm 301 in a controlled manner, so that it turns with the pressing plate 103 to enclose the pole piece 210 on the fixture; D cylinder 141 and E cylinder, D cylinder 141, E cylinder 142 are respectively connected with A nozzle 140, corresponding to the installation of the first sealing mechanism 400, A nozzle 140 moves vertically and horizontally, blows out ion wind to flatten the diaphragm 301 The pole piece 210 is attached to facilitate sealing.

[0041] The position of the feeding mechanism 200 shown corresponds to the feeding station setting of the positioning mechanism 100, and includes a storage tank 201, a positioner 202, a manipulator 203, and a suction cup 205. The pole piece 210 is stored in the storage tank 201, The plurality of storage tanks 201 are divided into two groups, which are switched by the indexer 202, and the A suction cup 205 sucks the pole piece 210 into the fixed plate 102 of the fixture.

[0042] The position of the laminating mechanism 300 shown corresponds to the feeding station of the positioning mechanism 100 next to the heat-sealing station, including the B motor 302, the reel 303, the gripper 304, the driver 305, and the film material 301. The driver 305 drives the gripper. 304 clamps the film material 301, sends the diaphragm into the fixed plate 102 of the aforementioned jig, and cuts the film material after placing the pole piece 210.

[0043] The sealing mechanism shown includes a first sealing mechanism 400 and a second sealing mechanism 500, which are respectively arranged at the top sealing station and the side sealing station of the heat sealing station, that is, the top edge and the side edge of the heat-press packaging diaphragm, Make it wrap the pole piece. The first sealing mechanism 400 is installed on the frame 10 and includes a seal A 401 and an F cylinder 402. The A seal 401 is aligned with one side of the package, and the built-in electric heating tube controls the temperature. The F cylinder 402 drives the hot pressing film 301 to Glue one side. The second sealing mechanism 500 shown is installed on the frame 10 and includes a G cylinder 501, an upper seal 502, a lower seal 503, and an H cylinder 504. The upper seal 502 has a built-in electric heating tube to control the temperature and is connected to the G cylinder 501. The lower seal 503 and The H cylinder 504 is connected, and the two are aligned up and down on the other side of the package. The G cylinder 501 and the H cylinder 504 drive both sides of the hot-pressing adhesive film 301.

[0044] The discharging mechanism 600 shown is installed on the side of the turntable 101 of the frame 10, and its position corresponds to the discharging station of the positioning mechanism 100. It includes a B robot 601, a B suction cup 602, a trough 603, a J cylinder 604, a cutter 605, The K cylinder 607 is connected to the cutter 605 to divide the multiple sealed packaging bags into a single section. The B suction cup 602 puts each packaged product into the trough 603.

[0045] The key point of the design of the present invention is that, on the one hand, the positioning mechanism is equipped with a special fixture to accurately position the film material and pole piece; ion wind is used to remove the static electricity of the film material before packaging and flatten it in the hot-press packaging, and the product packaging effect is good. ; On the other hand, its feeding mechanism, discharging mechanism and packaging mechanism can complete multiple pole piece operations at one time and collect materials into the trough. In this way, the pole piece can be packaged with a diaphragm reliably, which has the advantages of simplicity, reliability, high speed, good product consistency, accurate positioning, and automatic operation.

[0046] The above are only the preferred embodiments of the present invention and do not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention belong to The protection scope of the technical solution of the present invention.
