Description

Technical Field

[0001] This application relates to the field of photovoltaic cell string production, specifically a cell processing device. Background Technology

[0002] To prevent localized stress on the edges of the cells caused by solder ribbons during the lamination of battery string modules, which could lead to microcracks in the cells, such as... Figure 11 As shown, during battery string production, a membrane strip 200 can be placed between two adjacent battery cells 100. The membrane strip 200 is bonded to the upper edge of one battery cell 100 and extends to the lower edge of the other battery cell 100. The membrane strip 200 buffers the stress exerted on the edge of the battery cell 100 by the solder ribbon 300. Before producing this type of battery string, the membrane strip 200 needs to be pre-bonded to the edge of the battery cell 100 to achieve the desired effect. Figure 12 The battery cell 100 shown has a membrane strip 200, and then several battery cells 100 with membrane strips 200 are connected in series to form a battery string by welding ribbon.

[0003] Furthermore, for this type of battery string, when defective cells are present, the defective cells and their associated membrane strips need to be removed from the string. A new cell with the membrane strip (i.e., the replacement cell) is then welded to the vacated position after the defective cell was removed. Similarly, the membrane strip needs to be bonded to the edge of the new cell to obtain the required replacement cell.

[0004] Existing solar cell processing devices, such as the cell supply mechanism in Chinese invention patent application CN119325296 A, can only bond membrane strips to the solar cells and cannot perform online fabrication of the membrane strips. Therefore, when the supply of membrane strips is untimely, it will lead to a decrease in the membrane strip bonding efficiency of the solar cells. Utility Model Content

[0005] To address the aforementioned technical problems, this application provides a battery cell processing apparatus, the detailed technical solution of which is as follows:

[0006] A solar cell processing apparatus includes a solar cell supply mechanism, a film strip feeding mechanism, a film strip traction mechanism, a film strip pressing and cutting mechanism, a film strip slitting mechanism, a cutting platform, a conveying mechanism, and a pre-adhesion mechanism, wherein:

[0007] The cell supply organization is configured to supply cells;

[0008] The cutting platform is configured to translate between the film-attaching station, the slitting station, and the film-removing station;

[0009] The film tape feeding mechanism is configured to carry the film tape roll and drive the film tape roll to rotate to feed the film tape.

[0010] The film belt pressing and cutting mechanism is located between the film belt feeding mechanism and the film belt traction mechanism. The free end of the film belt released from the film belt roll is pressed by the film belt pressing and cutting mechanism. The film belt traction mechanism is configured to clamp the free end of the film belt from the film belt pressing and cutting mechanism and to pull the clamped film belt to the cutting platform located at the film splicing station.

[0011] The film belt pressing and cutting mechanism is configured to press and cut the film belt to obtain a film sheet on the cutting platform;

[0012] The film strip slitting mechanism is set at the slitting station and is configured to slit the film sheet on the cutting platform at the slitting station to obtain several film strips;

[0013] The conveying mechanism is configured to pick up film strips from the cutting platform, pick up solar cells from the solar cell supply mechanism, and stack the picked-up film strips and solar cells onto the pre-adhesion mechanism, wherein the film strips are stacked to the edge of the solar cells;

[0014] The pre-adhesion mechanism is configured to pre-adhere the membrane strip to the solar cell.

[0015] The solar cell processing apparatus provided in this application comprises a film strip traction mechanism, a film strip pressing and cutting mechanism, a film strip slitting mechanism, and a cutting platform that work together to automatically cut film sheets from the film strip roll and automatically slit the film sheets into several film strips, thereby realizing the online preparation of film strips. This allows the conveying mechanism to promptly pick up the film strips from the cutting platform and stack the film strips and solar cells picked up from the solar cell supply mechanism onto the pre-bonding mechanism to complete the bonding of the film strips and solar cells, avoiding a decrease in film strip bonding efficiency due to untimely film strip supply.

[0016] In some embodiments, the film tape pressing and cutting mechanism includes a first mounting frame, a first pressing component, a cutting component, and a second pressing component, wherein: the first pressing component, the cutting component, and the second pressing component are all disposed on the first mounting frame; the film tape passes sequentially through the first pressing component and the second pressing component, wherein the first pressing component is configured to press the film tape from a first side of the cutting component, and the second pressing component is configured to press the film tape from a second side of the cutting component to a first end of a cutting platform located at the film splicing station, the first end of the cutting platform being the end of the cutting platform closest to the film tape pressing and cutting mechanism; the cutting component is configured to cut the pressed film tape between the first pressing component and the second pressing component to obtain a film sheet on the cutting platform.

[0017] As the membrane strip passes through the first pressing assembly and the second pressing assembly in sequence, when the cutting assembly cuts the membrane strip, the first pressing assembly and the second pressing assembly press the membrane strip from both sides of the cutting assembly, so that the membrane strip is fully taut when it is cut, thereby forming a straight cut and ultimately ensuring that a membrane with a straight edge is obtained.

[0018] In some embodiments, the first pressing assembly includes a pressure plate, a first pressure plate, and a first lifting drive, wherein: the pressure plate is disposed on a first mounting frame; the first lifting drive is disposed on the first mounting frame, the first pressure plate is connected to a movable part of the first lifting drive, and the first pressure plate is located above the pressure plate; the film strip passes between the first pressure plate and the pressure plate, and the first lifting drive is configured to drive the first pressure plate to rise and fall to press the film strip onto the pressure plate or release the film strip; the second pressing assembly includes a second pressure plate and a second lifting drive, wherein: the second lifting drive is disposed on the first mounting frame, the second pressure plate is connected to a movable part of the second lifting drive; the second lifting drive is configured to drive the second pressure plate to rise and fall to press the film strip onto a first end of the cutting platform or release the film strip; a cutting gap is provided between the first pressure plate and the second pressure plate for the cutter of the cutting assembly to pass through.

[0019] The first lifting drive unit moves the first pressure plate up or down toward or away from the pressure plate, enabling rapid pressing and releasing of the film strip passing between the first pressure plate and the pressure plate. The second lifting drive unit moves the second pressure plate up or down toward or away from the first end of the cutting platform, enabling the film strip to be pressed against the first end of the cutting platform from the second side of the cutting assembly or released from the film strip. The cutting gap between the first and second pressure plates provides movement and cutting space for the cutting assembly, allowing it to move perpendicularly across the cutting gap to cut the film strip.

[0020] In some embodiments, a plurality of clearance grooves are arranged side by side at intervals at one end of the pressure plate near the second pressure plate, and a plurality of pressure teeth are arranged side by side at intervals at the bottom of the first pressure plate, with clearance gaps formed between adjacent pressure teeth, and the clearance gaps corresponding one-to-one with the clearance grooves; the membrane belt traction mechanism includes a plurality of clamping members arranged side by side, with the clamping members corresponding one-to-one with the clearance grooves, and each clamping member passes through the corresponding clearance gap and clearance groove to clamp the free end of the membrane belt.

[0021] When the membrane belt is cut, the edge of the new free end of the membrane belt is flush with the edges of the pressure plate and the first pressure plate. In other words, the free end of the membrane belt is pressed between the pressure plate and the first pressure plate. By providing clearance grooves and clearance gaps at the ends of the pressure plate and the bottom of the first pressure plate, the areas of the pressed free end of the membrane belt corresponding to the clearance grooves and clearance gaps can be exposed. This allows the clamping members of the membrane belt traction mechanism to pass through the corresponding clearance gaps and clearance grooves to clamp the free end of the membrane belt.

[0022] In some embodiments, the cutting assembly includes a first translational drive and a cutter, wherein: the first translational drive is disposed on a first mounting bracket, and the cutter is connected to a movable part of the first translational drive; the first translational drive is configured to drive the cutter to translate along a direction perpendicular to the traction direction of the film strip, so that the cutter passes through the cutting gap to cut the film strip.

[0023] The first translational drive unit drives the cutter to pass through the cutting gap from the side of the film strip to cut the film strip. On the one hand, this ensures a complete cut of the film strip. On the other hand, it eliminates the need for a corresponding cutting plate to cut the film strip, thus simplifying the structure of the cutting assembly.

[0024] In some embodiments, the first mounting bracket includes a first mounting support, a second mounting support, and a third lifting drive, wherein: the second mounting support is slidably and vertically connected to the first mounting support; both the first clamping assembly and the second clamping assembly are disposed on the second mounting support; and the cutting assembly is disposed on the first mounting support; the third lifting drive is disposed on the first mounting support and is configured to drive the second mounting support to move up and down between a first high position and a first low position; when the third lifting drive drives the second mounting support to descend to the first low position, the film strip is laid on the cutting platform; when the third lifting drive drives the second mounting support to rise to the first high position, the new free end of the film strip after cutting is higher than the cutting platform.

[0025] The first and second clamping components are mounted on a liftable second mounting bracket driven by a third lifting drive. When the film belt traction mechanism pulls the film belt onto the cutting platform, the second mounting bracket descends to its first low position, and the film belt traction mechanism also descends synchronously, thus laying the film belt onto the cutting platform and clamping it for subsequent cutting. After the cutting component cuts the film belt, the second mounting bracket is raised to its first high position, and the first clamping component lifts the clamped film belt. This ensures that the new free end of the film belt after cutting is higher than the support platform, facilitating the film belt traction mechanism to clamp the new free end of the film belt at a high position during the next cut, and preventing interference between the film belt traction mechanism and the cutting platform when pulling the film belt.

[0026] In some embodiments, the film strip slitting mechanism includes a first movable module, a second mounting frame, a film pressing plate, and a slitting assembly, wherein: the second mounting frame is connected to a movable part of the first movable module; the film pressing plate is buoyantly connected to the bottom of the second mounting frame via a first buffer connector, and the film pressing plate is provided with a plurality of slitting slits running from top to bottom through the film pressing plate; the slitting assembly is disposed on the second mounting frame and located above the film pressing plate; the first movable module is configured to drive the second mounting frame to move, thereby causing the film pressing plate to press the film sheet located on the cutting platform at the slitting station; the slitting assembly is configured to pass through the plurality of slitting slits to slit the pressed film sheet into a plurality of film strips.

[0027] The pressure plate first presses the film sheet on the cutting platform at the slitting station under the drive of the first moving module. Then, the slitting component passes through several slitting slits on the pressure plate and cuts the pressed film sheet into several film strips. This ensures the slitting quality of the film sheet and guarantees that the obtained film strips have straight edges. In addition, since the pressure plate is buoyantly connected to the bottom of the second mounting frame via the first buffer connector, the pressure plate can achieve elastic pressing of the film sheet. This ensures that the pressure plate can achieve all-round pressing of the film sheet, ultimately improving the slitting effect of the film sheet.

[0028] In some embodiments, the slitting assembly includes a second translational drive, a mounting plate, a fourth lifting drive, a vibration module, a cutter holder, and a plurality of blades, wherein: the mounting plate is buoyantly connected to the movable part of the second translational drive via a second buffer connector; the fourth lifting drive is disposed on the mounting plate; the cutter holder is connected to the movable part of the fourth lifting drive; and a plurality of blades are arranged side-by-side on the cutter holder and correspond one-to-one with the slitting slits; the fourth lifting drive is configured to drive the cutter holder to descend, so that the plurality of blades pass downward through the corresponding slitting slits; the second translational drive is configured to drive the cutter holder to reciprocate along the extension direction of the slitting slits, thereby driving the plurality of blades to slit the diaphragm into a plurality of diaphragm strips; the vibration module is disposed on the movable part of the second translational drive and drivenly connected to the mounting plate, and the vibration module is configured to drive the mounting plate to vibrate up and down relative to the movable part of the second translational drive.

[0029] By configuring the slitting assembly, it can pass downwards through several slitting slits on the pressure plate and slit the membrane sheet into several strips in one go, thereby improving the slitting efficiency. Furthermore, during the slitting process, the vibration module drives the mounting plate to vibrate up and down, which in turn causes the blades to vibrate synchronously. This vibration effectively reduces the continuous friction force experienced by the blades during cutting, further improving the slitting effect and resulting in strips with straighter edges and reduced debris.

[0030] In some embodiments, the vibration module includes a vibration motor, an eccentric shaft, a follower, and a vibration frame, wherein: the vibration frame is fixedly connected to the mounting plate, and the vibration frame is provided with an oblong hole; the vibration motor is disposed on the movable part of the second translation drive, the eccentric shaft is drivenly connected to the vibration motor, the follower is disposed on the eccentric shaft and located in the oblong hole; the vibration motor is configured to drive the eccentric shaft to rotate, so as to drive the mounting plate to vibrate up and down relative to the movable part of the second translation drive via the follower and the vibration frame.

[0031] A simple vibration module is provided, in which a vibration motor drives an eccentric shaft to rotate, and the eccentric shaft pushes a follower to slide in the waist-shaped hole of the vibration frame, thereby causing the vibration frame to vibrate, and finally causing the mounting plate to vibrate up and down relative to the moving part of the second translation drive.

[0032] In some embodiments, the film strip slitting mechanism further includes two first alignment components disposed at the bottom of the second mounting frame; the first alignment component includes a drive member and an alignment member that is drively connected to the drive member, the alignment members of the two first alignment components are disposed opposite to each other and located below the pressure plate; the two alignment members are configured to move closer to each other or further away from each other, and when they move closer to each other, they correct the position of the film on the cutting platform.

[0033] By setting two first straightening components on opposite sides of the pressure plate, the position of the membrane can be corrected before the membrane is cut, so that the opposite two side edges of the membrane are parallel to the cutting slit on the pressure plate, and finally ensure that a rectangular membrane strip can be obtained after the membrane is cut.

[0034] In some embodiments, a plurality of slitting grooves are arranged side by side at intervals on the cutting platform. The slitting grooves correspond one-to-one with the slitting slits and extend in the same direction. Each blade extends downward through the corresponding slitting slit and then into the corresponding slitting groove. The cutting platform is also provided with a plurality of first adsorption holes for adsorbing the film.

[0035] By incorporating slitting grooves on the cutting platform, the membrane strip slitting mechanism is bypassed, allowing each cutter of the slitting mechanism to first enter its corresponding slitting groove after descending, and then move towards the membrane sheet to cut it, thus smoothly obtaining membrane strips. By providing a first suction hole on the bearing surface of the cutting platform, the platform can receive and hold the membrane sheet, preventing displacement during platform movement and ensuring the quality of the membrane strip slitting. After the membrane sheet is slitting, the membrane strip is held adsorbed on the cutting platform, preventing misalignment during platform movement, and ultimately ensuring that the conveying mechanism can smoothly pick up the membrane strip from the cutting platform.

[0036] In some embodiments, the cutting platform includes a third mounting frame, a first platform, a second platform, and a fifth lifting drive, wherein: the first platform is disposed on the third mounting frame; the fifth lifting drive is disposed on the third mounting frame; the second platform is connected to a movable part of the fifth lifting drive and is located at the end of the first platform away from the film belt pressing and cutting mechanism; the fifth lifting drive is configured to drive the second platform to move up and down between a second high position and a second low position; when the second platform descends to the second low position, the bearing surface of the second platform is lower than the bearing surface of the first platform, and the film belt traction mechanism pulls the clamped film belt onto the first platform, the film belt traction mechanism being located above the second platform; after the film belt traction mechanism releases the film belt, the second platform rises to the second high position, the bearing surface of the second platform is at the same height as the bearing surface of the first platform, and the bearing surface of the second platform carries the free end of the film belt released by the film belt traction mechanism.

[0037] By configuring the cutting platform, it is ensured that after the membrane belt traction mechanism pulls the membrane belt onto the cutting platform, the free end of the membrane belt can also bear and adhere tightly to the bearing surface of the cutting platform, and interference between the membrane belt traction mechanism and the cutting platform is avoided.

[0038] In some embodiments, the film belt traction mechanism includes a second moving module, a clamping plate, a pressure plate, a pressure plate drive, a rotating shaft, and a plurality of grippers, wherein: the clamping plate is connected to a movable part of the second moving module, and the second moving module is configured to drive the clamping plate to translate and move up and down; the rotating shaft is disposed on the clamping plate, and a plurality of grippers are rotatably connected to the rotating shaft side by side, a compression spring is disposed between the first end of the gripper and the clamping plate, and the second end of the gripper is a clamping end; the pressure plate drive is disposed on the clamping plate, and the pressure plate is connected to a movable part of the pressure plate drive, and the pressure plate drive is configured to drive the pressure plate to move toward or away from the plurality of grippers; when the pressure plate drive drives the pressure plate to move toward the plurality of grippers, the pressure plate drives the first ends of the plurality of grippers to move downward, and a clamping gap for the film belt to enter is formed between the clamping ends of the plurality of grippers and the clamping plate, and the compression spring is compressed; when the pressure plate drive drives the pressure plate to move away from the plurality of grippers, the compression spring is depressurized and rebounds, and the clamping ends of the grippers press the film belt tightly onto the clamping plate.

[0039] A simple and stable film strip traction mechanism is provided, which can ensure that the free end of the film strip is clamped from the film strip pressing and cutting mechanism and the clamped film strip is pulled to the cutting platform.

[0040] In some embodiments, the conveying mechanism includes a third moving module, a fourth mounting frame, a sixth lifting drive, a suction cup assembly, and an adsorption strip, wherein: the fourth mounting frame is connected to a movable part of the third moving module; the suction cup assembly and the sixth lifting drive are both disposed on the fourth mounting frame; the adsorption strip is connected to the movable part of the sixth lifting drive via a third buffer connector, and the sixth lifting drive is configured to drive the adsorption strip to move up and down between a third high position and a third low position; when the adsorption strip rises to the third high position, the adsorption surface of the adsorption strip is higher than the adsorption end of the suction cup assembly, and the third moving module is configured to drive the fourth mounting frame to move, so as to drive the suction cup assembly to pick up the battery cell from the battery cell supply mechanism and place the battery cell on the pre-adhesion mechanism; when the adsorption strip falls to the third low position, the adsorption surface of the adsorption strip is lower than the adsorption end of the suction cup assembly, and the third moving module is configured to drive the fourth mounting frame to move, so as to drive the adsorption strip to pick up the film strip from the film strip supply mechanism and place the film strip on the battery cell of the pre-adhesion mechanism.

[0041] By configuring the handling mechanism, it can handle both solar cells and membrane strips, thereby reducing equipment costs.

[0042] In some embodiments, the pre-adhesion mechanism includes a fifth mounting frame, a pre-adhesion platform, and a second alignment component, wherein: the pre-adhesion platform is disposed on the fifth mounting frame, a heating component is disposed within the pre-adhesion platform, and a second adsorption hole is disposed on the bearing surface of the pre-adhesion platform; the pre-adhesion platform is configured to adsorb and heat the film strip and the battery cell, so that the film strip is pre-adheded to the battery cell; the second alignment component is disposed on the fifth mounting frame and located on the periphery of the pre-adhesion platform, and the second alignment component is configured to align the position of the battery cell placed on the pre-adhesion platform.

[0043] By incorporating a heating component within the pre-bonding platform and providing a second adsorption hole on its bearing surface, the platform adsorbs and heats the battery cells when the transport mechanism stacks them onto the platform. When the transport mechanism places the film strip at the edge of the battery cell, the film strip is then bonded to the cell. Furthermore, a second alignment component on the periphery of the pre-bonding platform ensures the battery cells are aligned with the platform, guaranteeing that the film strip is aligned with the battery cells when stacked.

[0066] To make the above-mentioned objects, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0067] As described in the background section, existing solar cell processing equipment can only bond membrane strips to solar cells and cannot perform online fabrication of membrane strips. Therefore, when the supply of membrane strips is untimely, it will lead to a decrease in the membrane strip bonding efficiency of the solar cells.

[0068] In view of this, this application provides a battery cell processing apparatus that can automatically prepare membrane strips and bond the prepared membrane strips to the battery cell.

[0069] like Figures 1 to 3 As shown, the solar cell processing apparatus of this application includes a solar cell supply mechanism (not shown in the figure), a film strip feeding mechanism 11, a film strip traction mechanism 12, a film strip pressing and cutting mechanism 13, a film strip slitting mechanism 14, a cutting platform 15, a conveying mechanism 3, and a pre-adhesion mechanism 4, wherein:

[0070] The cell supply organization is configured to supply cells.

[0071] The cutting platform 15 is configured to translate between the film-attaching station E, the slitting station F, and the film-removing station G.

[0072] The film tape feeding mechanism 11 is configured to carry the film tape roll 500 and drive the film tape roll 500 to rotate to feed the film tape.

[0073] The film tape pressing and cutting mechanism 13 is located between the film tape feeding mechanism 11 and the film tape traction mechanism 12. The free end of the film tape released from the film tape roll 500 is pressed by the film tape pressing and cutting mechanism 13. The film tape traction mechanism 12 is configured to clamp the free end of the film tape from the film tape pressing and cutting mechanism 13 and to pull the clamped film tape to the cutting platform 15 located at the film splicing station.

[0074] The film tape pressing and cutting mechanism 13 is configured to press and cut the film tape to obtain a film sheet on the cutting platform 15.

[0075] The film strip slitting mechanism 14 is located at the slitting station and is configured to slit the film sheet on the cutting platform 15 located at the slitting station to obtain several film strips.

[0076] The conveying mechanism 3 is configured to pick up film strips from the cutting platform 15, pick up solar cells from the solar cell supply mechanism, and stack the picked-up film strips and solar cells onto the pre-adhesion mechanism 4, wherein the film strips are stacked at the edge of the solar cells.

[0077] The pre-adhesion mechanism 4 is configured to pre-adhere the membrane strip to the battery cell.

[0078] The optional operation process of the battery cell processing apparatus in this application embodiment is as follows:

[0079] In the initial state, the free end of the film strip released from the film roll is pressed into the film strip pressing and cutting mechanism 13.

[0080] The cutting platform 15 moves to the film bonding station E, and the film belt traction mechanism 12 clamps the free end of the film belt from the film belt pressing and cutting mechanism 13. Then the film belt pressing and cutting mechanism 13 releases the welding strip, and the film belt traction mechanism 12 can pull the clamped film belt onto the cutting platform 15.

[0081] Next, the membrane tape pressing and cutting mechanism 13 presses the membrane tape again and cuts the membrane tape to obtain a membrane sheet on the cutting platform 15.

[0082] Next, the cutting platform 15 carries the film sheet to the slitting station F, where the film strip slitting mechanism 14 cuts the film sheet on the cutting platform 15 to obtain several film strips. Subsequently, the cutting platform 15 carries the several film strips to the film taking station G.

[0083] Next, the conveying mechanism 3 picks up solar cells from the solar cell supply mechanism and stacks the picked-up solar cells onto the pre-bonding mechanism 4. Subsequently, the conveying mechanism 3 picks up film strips from the cutting platform 15 and stacks the film strips onto the solar cells. The pre-bonding mechanism 4 pre-bonds the film strips onto the solar cells, thereby obtaining the desired result. Figure 12 The battery cell 100 shown has a membrane strip 200.

[0084] As can be seen, the solar cell processing apparatus provided in this application, wherein the film strip traction mechanism 12, film strip pressing and cutting mechanism 13, film strip slitting mechanism 14 and cutting platform 15 cooperate with each other to automatically cut the film from the film strip roll and automatically cut the film into several film strips, thereby realizing the online preparation of film strips. This allows the conveying mechanism 3 to pick up the film strips from the cutting platform 15 in a timely manner and stack the film strips and the solar cells picked up from the solar cell supply mechanism onto the pre-bonding mechanism 4 to complete the bonding of the film strips and the solar cells, avoiding the reduction of film strip bonding efficiency due to untimely film strip supply.

[0085] Optionally, the cutting platform 15 is connected to the third translation drive, which drives the cutting platform 15 to translate and switch between the film receiving station E, the slitting station F, and the film taking station G. The third translation drive can be any existing linear drive that can drive the cutting platform 15 to reciprocate, such as a drive consisting of a cylinder or motor, a lead screw, a lead screw nut, and a slider.

[0086] like Figures 2 to 3 As shown, optionally, the film tape pressing and cutting mechanism 13 includes a first mounting frame 131, a first pressing assembly 132, a cutting assembly 133, and a second pressing assembly 134, wherein the first pressing assembly 132, the cutting assembly 133, and the second pressing assembly 134 are all disposed on the first mounting frame 131. The film tape passes sequentially through the first pressing assembly 132 and the second pressing assembly 134, wherein the first pressing assembly 132 is configured to press the film tape from a first side (e.g., the left side) of the cutting assembly 133, and the second pressing assembly 134 is configured to press the film tape from a second side (e.g., the right side) of the cutting assembly 133 to a first end (e.g., the left end) of the cutting platform 15 located at the film splicing station, the first end of the cutting platform 15 being the end of the cutting platform 15 closest to the film tape pressing and cutting mechanism 13. The cutting assembly 133 is configured to cut the pressed film tape between the first pressing assembly 132 and the second pressing assembly 134 to obtain a film sheet on the cutting platform 15.

[0087] As the membrane strip passes through the first pressing assembly 132 and the second pressing assembly 134 in sequence, when the cutting assembly 133 cuts the membrane strip, the first pressing assembly 132 and the second pressing assembly 134 press the membrane strip from both sides of the cutting assembly 133, so that the membrane strip is fully taut when it is cut, thereby forming a straight cut and ultimately ensuring that a membrane with a straight edge is obtained.

[0088] Optionally, the first pressing assembly 132 includes a pressure plate 1321, a first pressure plate 1322, and a first lifting drive 1323, wherein: the pressure plate 1321 is disposed on the first mounting bracket 131; the first lifting drive 1323 is disposed on the first mounting bracket 131; the first pressure plate 1322 is connected to a movable part of the first lifting drive 1323, and the first pressure plate 1322 is located above the pressure plate 1321; the membrane tape passes between the first pressure plate 1322 and the pressure plate 1321; and the first lifting drive 1323 is configured to drive the first pressure plate 1322 to rise or fall, thereby pressing the membrane tape against the pressure plate 1321 or releasing the membrane tape.

[0089] The first lifting drive 1323 drives the first pressure plate 1322 to move up or down toward or away from the pressure plate 1321, thereby achieving rapid pressing and releasing of the membrane strip passing between the first pressure plate 1322 and the pressure plate 1321. The first lifting drive 1323 can be any existing linear drive, such as a cylinder or an electric cylinder.

[0090] Optionally, the second pressing assembly 134 includes a second pressure plate 1341 and a second lifting drive 1342, wherein: the second lifting drive 1342 is disposed on the first mounting bracket 131, and the second pressure plate 1341 is connected to a movable part of the second lifting drive 1342. The second lifting drive 1342 is configured to drive the second pressure plate 1341 to rise and fall, so as to press the film strip to the first end of the cutting platform 15 or release the film strip. A cutting gap H is provided between the first pressure plate 1322 and the second pressure plate 1341 for the cutter 1332 of the cutting assembly 133 to pass through.

[0091] The second lifting drive 1342 drives the second pressure plate 1341 to move towards or away from the first end of the cutting platform 15, thereby pressing the film strip to the first end of the cutting platform 15 from the second side of the cutting assembly 133 or releasing the film strip. The cutting gap H between the first pressure plate 1322 and the second pressure plate 1341 provides the cutting assembly 133 with movement and cutting space, allowing the cutting assembly 133 to move across the cutting gap perpendicular to the length direction of the welding strip to cut the film strip. The second lifting drive 1342 can also be any existing linear drive, such as a cylinder or electric cylinder.

[0092] After the membrane tape is cut by the cutting assembly 133, the edge of the new free end of the membrane tape produced by the cutting is almost flush with the edge of the pressure plate 1321 and the first pressure plate 1322. That is, the free end of the membrane tape is pressed between the pressure plate 1321 and the first pressure plate 1322. In order to enable the membrane tape traction mechanism 12 to smoothly clamp the free end of the membrane tape.

[0093] like Figure 2 As shown, optionally, the end of the pressure plate 1321 near the second pressure plate 1341 (e.g., the right end) is provided with a plurality of clearance grooves 1324 spaced apart side by side, and the bottom of the first pressure plate 1322 is provided with a plurality of pressure teeth spaced apart side by side, with clearance gaps 1325 formed between adjacent pressure teeth, and the clearance gaps 1325 corresponding one-to-one with the clearance grooves 1324. The membrane belt traction mechanism 12 includes a plurality of clamping members arranged side by side, each clamping member corresponding one-to-one with the clearance grooves 1324, and each clamping member passes through the corresponding clearance gap 1325 and clearance groove 1324 to clamp the free end of the membrane belt.

[0094] By providing clearance grooves 1324 and clearance gaps 1325 at the ends of the pressure plate 132 and the bottom of the first pressure plate 1322 respectively, the free end of the membrane belt is exposed in the area corresponding to the clearance grooves 1324 and clearance gaps 1325. In this way, each clamping member of the membrane belt traction mechanism 12 can pass through the corresponding clearance gaps 1325 and clearance grooves 1324 to clamp the free end of the membrane belt.

[0095] like Figure 2As shown, optionally, the cutting assembly 133 includes a first translation drive 1331 and a cutter 1332, wherein: the first translation drive 1331 is disposed on the first mounting bracket 131, and the cutter 1332 is connected to the movable part of the first translation drive 1331; the first translation drive 1331 is configured to drive the cutter 1332 to translate along a direction perpendicular to the traction direction of the film strip, so that the cutter 1332 passes through the cutting gap H to cut the film strip.

[0096] The first translation drive 1331 drives the cutter 1332 to pass through the cutting gap H from the side of the film strip to cut the film strip. On the one hand, it can ensure the complete cutting of the film strip. On the other hand, it can cut the film strip without setting a cutting plate corresponding to the cutter 1332, thus making the structure of the cutting assembly 133 simpler.

[0097] The first translation drive 1331 can be any existing linear drive that can drive the cutter 1332 to translate along a direction perpendicular to the traction direction of the film belt, such as a cylinder or an electric cylinder.

[0098] like Figure 3 As shown, optionally, the first mounting frame 131 includes a first mounting bracket 1311, a second mounting bracket 1312, and a third lifting drive 1313, wherein: the second mounting bracket 1312 is slidably and vertically connected to the first mounting bracket 1311; the first clamping assembly 132 and the second clamping assembly 134 are both disposed on the second mounting bracket 1312; and the cutting assembly 133 is disposed on the first mounting bracket 1311; the third lifting drive 1313 is disposed on the first mounting bracket 1311 and is configured to drive the second mounting bracket 1312 to move up and down between a first high position and a first low position; when the third lifting drive 1313 drives the second mounting bracket 1312 down to the first low position, the film strip is laid on the cutting platform 15; when the third lifting drive 1313 drives the second mounting bracket 1312 up to the first high position, the new free end of the film strip after cutting is higher than the cutting platform 15.

[0099] The first clamping assembly 132 and the second clamping assembly 134 are mounted on the liftable second mounting bracket 1312 driven by the third lifting drive 1313. When the film belt traction mechanism 12 pulls the film belt above the cutting platform 15, the second mounting bracket 1312 descends to the first low position, and the film belt traction mechanism 12 also descends synchronously, thereby enabling the film belt to be laid on the cutting platform 15 and clamped for subsequent cutting.

[0100] After the cutting component 133 cuts the film strip, the second mounting bracket 1312 is controlled to rise to the first high position, and the first clamping component 132 lifts the clamped film strip, so that the new free end of the film strip after cutting is higher than the cutting platform 15, which makes it convenient for the film strip traction mechanism 1 to clamp the new free end of the film strip at the high position during the next cutting, and avoids interference between the film strip traction mechanism 12 and the cutting platform 15 when pulling the film strip.

[0101] Optionally, the second mounting bracket 1312 is slidably and vertically connected to the first mounting bracket 1311 via a slide rail pair. The third lifting drive 1313 can be any existing linear drive that can drive the second mounting bracket 1312 to lift and slide, such as a cylinder or an electric cylinder.

[0102] like Figure 6 As shown, optionally, the film strip slitting mechanism 14 includes a first moving module 141, a second mounting frame 142, a film pressing plate 143, and a slitting assembly 144, wherein: the second mounting frame 142 is connected to the movable part of the first moving module 141. The film pressing plate 143 is buoyantly connected to the bottom of the second mounting frame 142 via a first buffer connector 145, and the film pressing plate 143 is provided with several slitting slits running from top to bottom through the film pressing plate 143; the slitting assembly 144 is disposed on the second mounting frame 142 and located on the upper side of the film pressing plate 143. The first moving module 141 is configured to drive the second mounting frame 142 to move, so as to cause the film pressing plate 143 to press the film sheet located on the cutting platform 15 at the slitting station. The slitting assembly 144 is configured to pass through the several slitting slits to slit the pressed film sheet into several film strips.

[0103] The pressure plate 143 first presses the film sheet on the cutting platform 15 located at the slitting station under the drive of the first moving module 141. Then, the slitting assembly 144 passes through several slitting slits on the pressure plate 143 and cuts the pressed film sheet into several film strips. This ensures the slitting quality of the film sheet and guarantees that the obtained film strips have straight edges. Furthermore, since the pressure plate 143 is buoyantly connected to the bottom of the second mounting bracket 142 via the first buffer connector 145, the pressure plate 143 can achieve elastic pressing of the film sheet, improving the pressing effect. The first buffer connector 145 can be, for example, a spring that can contract vertically when compressed.

[0104] The first moving module 141 can employ various existing drive devices capable of driving the second mounting frame 142 to move up and down and translate. For example, the first moving module 141 includes a translation drive unit and a lifting drive unit, wherein the lifting drive unit is connected to the movable part of the translation drive unit, and the second mounting frame 142 is connected to the movable part of the lifting drive unit. The lifting drive unit is used to drive the second mounting frame 142 to move up and down, and the translation drive unit is used to drive the second mounting frame 142 to translate. The first moving module 141 can also employ other drive devices such as a robotic arm.

[0105] like Figures 6 to 7 As shown, optionally, the slitting assembly 144 includes a second translation drive 1441, a mounting plate 1442, a fourth lifting drive 1443, a vibration module 1444, a cutter holder 1445, and a plurality of blades 1446. The mounting plate is buoyantly connected to the movable part of the second translation drive 1441 via a second buffer connector 1447. The fourth lifting drive 1443 is mounted on the mounting plate 1442. The cutter holder 1445 is connected to the movable part of the fourth lifting drive 1443. The plurality of blades 1446 are arranged side-by-side on the cutter holder 1445 and correspond one-to-one with the slitting seams. The fourth lifting drive 1443 is configured to drive the cutter holder 1445 to descend, causing the plurality of blades 1446 to pass downward through the corresponding slitting seams. The second translation drive 1441 is configured to drive the cutter holder 1445 to reciprocate along the extension direction of the slitting seams, thereby causing the plurality of blades 1446 to slit the diaphragm into a plurality of diaphragm strips. Vibration module 1444 is disposed on the movable part of second translation drive 1441 and drivenly connected to mounting plate 1442. Vibration module 1444 is configured to drive mounting plate 1442 to vibrate up and down relative to the movable part of second translation drive 1441.

[0106] By configuring the slitting assembly 144, it can pass downward through several slitting slits on the pressure plate 143 and slit the film into several film strips in one go, improving the slitting efficiency of the film. In addition, during the slitting process, the vibration module 1444 drives the mounting plate 1442 to vibrate up and down, which in turn drives the blade 1446 to vibrate up and down synchronously. The vibration can effectively reduce the continuous friction force experienced by the blade 1446 during cutting, thereby further improving the slitting effect of the film, obtaining film strips with straighter edges, and reducing debris.

[0107] The second translation drive 1441 can be any existing linear drive capable of driving the mounting plate 1442 to reciprocate, such as a drive consisting of a motor, a lead screw, a lead screw nut, and a slider. The mounting plate 1442 is connected to the bottom of the slider via the second buffer connector 1447. The motor drives the lead screw to rotate, thereby causing the lead screw nut and the slider to translate, thus driving the mounting plate 1442 to translate synchronously. The second buffer connector 1447 can be, for example, a spring that can contract vertically when compressed.

[0108] like Figure 7 As shown, optionally, the vibration module 1444 includes a vibration motor 1448, an eccentric shaft 1449, a follower 1450, and a vibration frame 1451, wherein: the vibration frame 1451 is fixedly connected to the mounting plate 1442, and the vibration frame 1451 is provided with an oblong hole. The vibration motor 1448 is mounted on the movable part of the second translation drive 1441, the eccentric shaft 1449 is drivenly connected to the vibration motor 1448, and the follower 1450 is mounted on the eccentric shaft 1449 and located within the oblong hole. The vibration motor 1448 is configured to drive the eccentric shaft 1449 to rotate, so as to drive the mounting plate 1442 to vibrate up and down relative to the movable part of the second translation drive 1441 via the follower 1450 and the vibration frame 1451.

[0109] Specifically, when the vibration motor 1448 drives the eccentric shaft 1449 to rotate, the eccentric shaft 1449 pushes the follower 1450 to slide in the waist-shaped hole of the vibration frame 1451, thereby causing the vibration frame 1451 to vibrate, and ultimately causing the mounting plate 1442 to vibrate up and down relative to the moving part of the second translation drive 1441.

[0110] Optionally, the vibration module can also be made of cylinder, which drives the vibration frame 1451 to move up and down to achieve vibration.

[0111] like Figure 6 As shown, optionally, the film strip slitting mechanism 14 further includes two first alignment components 146 disposed at the bottom of the second mounting bracket 142, with the two first alignment components 146 located on opposite sides of the pressure plate 143. Each first alignment component 146 includes a driving member and alignment members that are driveably connected to the driving member. The alignment members of the two first alignment components 146 are disposed opposite each other and located below the pressure plate 143. The two alignment members are configured to move closer to or further away from each other; when they move closer, they correct the position of the film on the cutting platform 15.

[0112] Specifically, the first moving module 141 first drives the second mounting bracket 142 to descend a predetermined height, so that the two first straightening components 146 are respectively located on opposite sides of the cutting platform 15, and the pressure plate 143 does not contact the film on the cutting platform 15. The driving components of the two first straightening components 146 synchronously drive the corresponding straightening components to move closer to each other, thereby correcting the position of the film on the cutting platform 15. Subsequently, the first moving module 141 drives the second mounting bracket 142 to continue descending until the pressure plate 143 presses the film onto the cutting platform 15.

[0113] As can be seen, by setting two first straightening components 146 on opposite sides of the pressure plate 143, the position of the membrane can be corrected before the membrane is cut, so that the opposite two side edges of the membrane are parallel to the cutting seam on the pressure plate 143, and finally ensure that a rectangular membrane strip is obtained after the membrane is cut.

[0114] The driving component can be, for example, a cylinder, while the regulating component can be a regulating plate or regulating bar connected to the telescopic rod of the cylinder.

[0115] like Figure 4 As shown, optionally, the cutting platform 15 has a plurality of slitting grooves 151 arranged side by side at intervals on its bearing surface. The slitting grooves 151 correspond one-to-one with the slitting slits and extend in the same direction. Each blade 1446 extends downward through the corresponding slitting slit and into the corresponding slitting groove 151, thereby cutting the film. The cutting platform 15 also has a plurality of first adsorption holes 152 for adsorbing the film on its bearing surface.

[0116] By setting a slitting groove 151 on the cutting platform, the blades 1446 of the film strip slitting mechanism 14 are avoided, allowing each blade 1446 of the film strip slitting mechanism 14 to first enter the corresponding slitting groove 151 after descending, and then move towards the film to cut the film, so as to smoothly obtain film strips. By setting a first adsorption hole 152 on the bearing surface of the cutting platform 15, the cutting platform 15 can receive the film and adsorb the film, avoiding displacement of the film during the movement of the cutting platform 15, which would affect the slitting and forming quality of the film strip. After the film is slitting is completed, the film strip is held adsorbed on the cutting platform 15, preventing the film strip from being misaligned during the movement of the cutting platform 15, and ultimately ensuring that the conveying mechanism can smoothly pick up the film strip from the cutting platform 15.

[0117] like Figure 4As shown, optionally, the cutting platform 15 includes a third mounting frame 153, a first platform 154, a second platform 155, and a fifth lifting drive 156, wherein: the first platform is mounted on the third mounting frame 153. The fifth lifting drive is mounted on the third mounting frame 153, and the second platform is connected to the movable part of the fifth lifting drive and located at the end of the first platform away from the film belt pressing and cutting mechanism 13. The fifth lifting drive 156 is configured to drive the second platform 155 to move up and down between a second high position and a second low position. When the second platform 155 descends to the second low position, the bearing surface of the second platform 155 is lower than the bearing surface of the first platform 154, and the film belt traction mechanism 12 pulls the clamped film belt onto the first platform 154. The film belt traction mechanism 12 is located above the second platform 155. After the membrane belt traction mechanism 12 releases the membrane belt, the second platform 155 rises to the second highest position. The bearing surface of the second platform 155 is at the same height as the bearing surface of the first platform 154. The bearing surface of the second platform 155 supports the free end of the membrane belt released by the membrane belt traction mechanism 12.

[0118] Specifically, before the membrane belt is laid onto the cutting platform 15, the second platform 155 first descends to the position shown by the membrane belt traction mechanism 12. Figure 4 At the second lowest position shown, when the film belt traction mechanism 12 lays the film belt onto the cutting platform 15, the second platform 155 can avoid the film belt traction mechanism 12, allowing the film belt traction mechanism 12 to pull the free end of the film belt above the second platform 155. Subsequently, the film belt traction mechanism 12 releases the film belt, and at the same time, the second platform 155 rises to the second highest position, so that the bearing surface of the second platform 155 and the bearing surface of the first platform 154 are restored to the same height. The film belt is jointly supported by the second platform 155 and the first platform 154, and the free end of the film belt is located on the bearing surface of the second platform 155.

[0119] It can be seen that by setting the cutting platform 15 in this way, it can be ensured that after the film belt traction mechanism 12 pulls the film belt onto the cutting platform 15, the free end of the film belt can also be supported and adhered to the bearing surface of the cutting platform 15.

[0120] like Figure 5As shown, optionally, the membrane belt traction mechanism 12 includes a second moving module 121, a clamping plate 122, a pressure plate 123, a pressure plate drive 124, a rotating shaft 125, and a plurality of grippers 126. The clamping plate 122 is connected to a movable part of the second moving module 121, and the second moving module 121 is configured to drive the clamping plate 122 to translate and move up and down. The rotating shaft 125 is disposed on the clamping plate 122, and a plurality of grippers are rotatably connected side-by-side to the rotating shaft 125. A compression spring is provided between the first end of each gripper 126 and the clamping plate 122, and the second end of each gripper 126 is a clamping end. The pressure plate drive 124 is disposed on the clamping plate 122, and the pressure plate 123 is connected to a movable part of the pressure plate drive 124. The pressure plate drive 124 is configured to drive the pressure plate 123 to move toward or away from the plurality of grippers 126. When the pressure plate drive 124 drives the pressure plate 123 to move toward the plurality of grippers 126, the pressure plate 123 causes the first ends of the plurality of grippers 126 to move downward, forming a gripping gap between the gripping ends of the plurality of grippers 126 and the clamping plate 122 for the film belt to enter, and the compression spring is compressed. When the pressure plate drive 124 drives the pressure plate 123 to move away from the plurality of grippers 126, the compression spring is depressurized and rebounds, and the gripping ends of the grippers 126 press the film belt tightly onto the clamping plate 122.

[0121] Specifically, when it is necessary to pull the film strip, the pressure plate drive 124 first drives the pressure plate 123 to move toward the plurality of grippers 126, thereby forming a gripping gap between the gripping ends of the plurality of grippers 126 and the gripping plate 122 for the film strip to enter. Subsequently, the second moving module 121 drives the gripping plate 122 to move toward the free end of the film strip to be gripped, until the free end of the film strip moves into the gripping gap between the gripping ends of the plurality of grippers 126 and the gripping plate 122. Subsequently, the pressure plate drive 124 drives the pressure plate 123 to move away from the plurality of grippers 126, and the gripping ends of the grippers 126 press the film strip onto the gripping plate 122 under the push of the compression spring, thereby performing the gripping of the film strip. Finally, the second moving module 121 drives the gripping plate 122 to move toward the cutting platform 15 to pull the film strip onto the cutting platform 15. Multiple grippers 126 work together to clamp the free end of the membrane strip from multiple positions, ensuring a strong clamping force on the free end of the membrane strip.

[0122] The second moving module 121 can employ various existing drive devices capable of driving the clamping plate 122 to rise, fall, and translate. For example, the second moving module 121 includes a translation drive unit and a lifting drive unit, wherein the lifting drive unit is connected to the movable part of the translation drive unit, and the clamping plate 122 is connected to the movable part of the lifting drive unit. The lifting drive unit is used to drive the clamping plate 122 to rise and fall, and the translation drive unit is used to drive the clamping plate 122 to translate. The second moving module 121 can also employ other drive devices capable of driving the clamping plate 122 to rise, fall, and translate, such as a robotic arm.

[0123] The pressure plate drive component 124 can be, for example, a cylinder, an electric cylinder, etc.

[0124] like Figures 8 to 9 As shown, optionally, the conveying mechanism package 3 includes a third moving module 31, a fourth mounting bracket 32, a sixth lifting drive component 33, a suction cup assembly 34, and an adsorption strip 35, wherein: the fourth mounting bracket is connected to the movable part of the third moving module; the suction cup assembly 34 and the sixth lifting drive component 33 are both mounted on the fourth mounting bracket 32; the adsorption strip 35 is connected to the movable part of the sixth lifting drive component 33 via a third buffer connector 36, and the sixth lifting drive component 33 is configured to drive the adsorption strip 35 to move up and down between a third high position and a third low position; the adsorption strip 35 When the adsorption strip 35 rises to the third highest position, the adsorption surface of the adsorption strip 35 is higher than the adsorption end of the suction cup assembly 34. The third moving module is configured to drive the fourth mounting frame to move, so as to drive the suction cup assembly 34 to pick up the battery cell from the battery cell supply mechanism and place the battery cell on the pre-adhesion mechanism. When the adsorption strip 35 falls to the third lowest position, the adsorption surface of the adsorption strip 35 is lower than the adsorption end of the suction cup assembly 34. The third moving module 31 is configured to drive the fourth mounting frame 32 to move, so as to drive the adsorption strip 35 to pick up the film strip from the film strip supply mechanism and place the film strip on the battery cell of the pre-adhesion mechanism.

[0125] Specifically, when it is necessary to move battery cells, the sixth lifting drive 33 first drives the adsorption strip 35 to the third highest position, so that the adsorption surface of the adsorption strip 35 is higher than the adsorption surface of the suction cup assembly 34. Then, the third moving module 31 drives the fourth mounting bracket 32 ​​to move, thereby causing the suction cup assembly 34 to pick up the battery cells from the battery cell supply mechanism 2 and place the battery cells on the pre-adhesion mechanism 4. When it is necessary to move film strips, the sixth lifting drive 33 first drives the adsorption strip 35 to the third lowest position, so that the adsorption surface of the adsorption strip 35 is lower than the adsorption surface of the suction cup assembly 34. Then, the third moving module 31 drives the fourth mounting bracket 32 ​​to move, thereby causing the adsorption strip 35 to pick up the film strip from the film strip supply mechanism 1 and place the film strip on the battery cells located in the pre-adhesion mechanism 4.

[0126] It is evident that by configuring the conveying mechanism 3, it is possible to convey both the battery cells and the membrane strips, thereby reducing equipment costs.

[0127] The third moving module 31 can employ various existing drive devices capable of driving the fourth mounting frame 32 to rise and move. For example, the third moving module 31 includes a translation drive unit and a lifting drive unit, wherein the lifting drive unit is connected to the movable part of the translation drive unit, and the fourth mounting frame 32 is connected to the movable part of the lifting drive unit. The lifting drive unit is used to drive the fourth mounting frame 32 to rise and fall, and the translation drive unit is used to drive the fourth mounting frame 32 to move. The third moving module 31 can also employ other drive devices capable of driving the fourth mounting frame 32 to rise and move, such as a robotic arm. The sixth lifting drive unit 33 can employ various existing drive units capable of driving the suction strip 35 to rise and fall, such as a cylinder or an electric cylinder.

[0128] Of course, in other embodiments, the suction strip 35 can be fixedly mounted on the fourth mounting bracket 32, and the suction cup assembly 34 can be connected to the sixth lifting drive member 33. The sixth lifting drive member 33 drives the suction cup assembly 34 to rise and fall, so that the suction surface of the suction cup assembly 34 is higher or lower than the suction surface of the suction strip 35. Specifically, when it is necessary to move the battery cell, the sixth lifting drive member 33 first drives the suction cup assembly 34 to fall, so that the suction surface of the suction strip 35 is higher than the suction surface of the suction cup assembly 34. Then, the third moving module 31 drives the fourth mounting bracket 32 ​​to move, thereby driving the suction cup assembly 34 to pick up the battery cell from the battery cell supply mechanism 2 and place the battery cell on the pre-adhesion mechanism 4. When it is necessary to move the film strip, the suction cup assembly 34 is first driven to rise by the sixth lifting drive 33, so that the adsorption surface of the adsorption strip 35 is lower than the adsorption surface of the suction cup assembly 34. Then, the third moving module 31 drives the fourth mounting frame 32 to move, thereby driving the adsorption strip 35 to pick up the film strip from the film strip supply mechanism 1 and place the film strip on the battery cell located in the pre-adhesion mechanism 4.

[0129] like Figure 10 As shown, optionally, the pre-adhesion mechanism 4 includes a fifth mounting frame 41, a pre-adhesion platform 42, and a second alignment component 43. The pre-adhesion platform 42 is mounted on the fifth mounting frame 41, and a heating component is installed within it. A second adsorption hole 44 is provided on the bearing surface of the pre-adhesion platform 42. The pre-adhesion platform 42 is configured to adsorb and heat the film strip and the battery cell, thereby pre-adheding the film strip to the battery cell.
