Description

Technical Field

[0001] This utility model relates to the field of battery processing technology, specifically to an automatic adhesive tape pasting mechanism for cylindrical battery cells. Background Technology

[0002] During the production of cylindrical batteries, adhesive tape needs to be pasted onto the circumferential head of the cylindrical cell. After the adhesive tape is pasted around the circumferential head of the cylindrical cell, it is cut off. After cutting, some adhesive tape still protrudes from the end face of the cylindrical cell. Usually, the adhesive tape protruding from the end face of the cylindrical cell is manually pressed and pasted back to the end face of the cell.

[0003] Manually pressing and pasting the adhesive tape extending from the cylindrical battery cell end face to the cell end face is labor-intensive and very inefficient. Utility Model Content

[0004] The purpose of this invention is to provide an automatic adhesive tape application mechanism to solve the problem of low production efficiency caused by manual tape application, pressing, and edge finishing.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] An automatic adhesive tape application mechanism includes a feeding device for feeding battery cells. A first power unit is located on one side of the bottom of the feeding device, and a battery cell receiving device is located on the other side. When the battery cell is at the bottom of the feeding device, the first power unit pushes the battery cell onto the receiving device. A sensor is located above the feeding device. A pressing device is located above the battery cell, and adhesive tape is located between the pressing device and the battery cell. A cutter is located on the side of the pressing device and above the adhesive tape. The receiving device is connected to a second power unit. When the pressing device presses the adhesive tape onto the battery cell, the second power unit drives the receiving device and the battery cell to rotate, and the adhesive tape is applied around the end of the battery cell. An adhesive tape retraction device is located on one side of the receiving device, pressing the portion of the adhesive tape protruding from the end of the battery cell onto the end face of the battery cell. The receiving device is mounted on a mounting component, which is connected to a third power unit. The third power unit tilts the mounting component. When the mounting component tilts, the battery cell slides down and is retracted along a feeding device.

[0007] Furthermore, the feeding device includes a ramp surface and vertical limiting plates located on both sides of the ramp surface. A U-shaped groove is provided at the end of the ramp surface, and a vertical limiting block is provided at the bottom of the ramp surface, with the limiting block located outside the U-shaped groove.

[0008] Furthermore, the first power unit includes a first cylinder, which is mounted on a limiting plate on one side, and the driving end of the first cylinder is connected to an L-shaped push plate.

[0009] Furthermore, the second power unit includes a drive motor, the receiving device includes a moving roller, the drive roller includes a driving roller and a driven roller, the driving roller and the driven roller are movably connected to the mounting parts on the horizontal mounting plate, and the driving roller and the driven roller are close to the notch on one of the limiting plates.

[0010] Furthermore, a vertical mounting plate is provided on one side of the horizontal mounting plate, and an adhesive tape applicator is provided on the vertical mounting plate. The adhesive tape applicator includes an adhesive tape tray, an adhesive tape pulling cylinder, a guide roller, an adhesive tape pressing cylinder, an adhesive tape receiving plate, and a U-shaped adhesive tape limiting component, all mounted on the vertical mounting plate. The adhesive tape receiving plate is used to receive the adhesive tape, and the U-shaped adhesive tape limiting component is provided on the adhesive tape receiving plate, with the U-shaped adhesive tape limiting component and the vertical mounting plate located on opposite sides of the adhesive tape receiving plate.

[0011] Furthermore, a clamping device is installed on the vertical mounting plate. The clamping device includes a pressing cylinder, which is mounted on the vertical mounting plate via a mounting bracket. Each pressing cylinder has a driving end connected to a clamping roller. When the pressing cylinder drives the clamping roller to move downward, the clamping roller contacts the battery cell located on the driving roller.

[0012] Furthermore, the vertical mounting plate is provided with an opening, and one end of the adhesive tape retracting device passes through the opening to contact the battery cell located on the drive roller. The adhesive tape retracting device includes an adhesive tape retracting cylinder, a support plate connected to the drive end of the adhesive tape retracting cylinder, an adhesive tape pressing cylinder located on the support plate, an adhesive tape pressing component connected to the drive end of the adhesive tape pressing cylinder, and a retracting tapered component connected to the end of the support plate facing the battery cell.

[0013] Furthermore, the adhesive tape pressing component includes a circular surface, a through hole in the center of the circular surface, and multiple planar pressing pieces evenly spaced along the circumference of the circular surface.

[0014] Furthermore, the conical component includes a ring with multiple flanges evenly spaced on the ring. The flanges and the battery cell are located on opposite sides of the ring, and each flange is at a preset angle to the surface of the ring. The ring and the multiple flanges form a cone shape. When the adhesive paper protruding from the end of the battery cell is pressed onto the end face of the battery cell by pressing the pressing piece, each pressing piece is located in the gap between two flanges.

[0015] Furthermore, the third power device includes a feeding cylinder, the drive end of the feeding cylinder is connected to a mounting component, and a vertical support component is connected to each side of the bottom surface of the mounting component. The two vertical support components are hinged to a hinge shaft at both ends, and the hinge shaft is located on two support seats (5-4) on the horizontal mounting plate.

[0016] The beneficial effects of this utility model are:

[0017] 1. This application can achieve automatic edge trimming after the adhesive tape is pasted. This application uses a power mechanism to automatically press and trim the edges, which is different from manual pressing. This application can make the adhesive tape protruding from the end face of the battery cell evenly pasted on the end face of the battery cell.

[0018] 2. Compared with the traditional manual pressing and finishing, this application realizes automatic pressing and finishing of the adhesive tape and automatic unloading after finishing, replacing manual labor and improving production efficiency. Attached Figure Description

Detailed Implementation

[0035] To make the purpose, technical solution and advantages of this utility model clearer, the present utility model will be further described below with reference to the accompanying drawings.

[0036] like Figure 1 , Figure 2 and Figure 3 As shown, the battery cell 1 is placed on the feeding device 2 manually. The battery cell feeding device 2 includes a ramp surface 2-1 and vertical limiting plates 2-2 located on both sides of the ramp surface 2-1. The ramp surface 2-1 is an inclined surface at a certain angle to the horizontal plane. The battery cell 1 slides down the ramp surface 2-1 to the bottom of the ramp surface 2-1. A vertical limiting block is set at the bottom of the ramp surface 2-1 to prevent the battery cell 1 from continuing to slide.

[0037] A sensor 3 is provided above the end of the slope 2-1. In one specific embodiment, the sensor 3 can be a reflective photoelectric sensor, which can be mounted on a bracket on the cell feeding device 2. The sensor 3 is positioned at the top of the mounting bracket, so that the sensor 3 is located above the end of the slope 2-1. The sensor 3 is used to detect whether there is a cell 1 at the end of the slope 2-1.

[0038] A first cylinder 4 is mounted on one of the limiting plates 2-2 via a mounting bracket. The first cylinder 4 is located on one side of the end of the ramp surface 2-1. The other limiting plate 2-2 has a notch at the end of the ramp surface 2-1. When the sensor 3 detects that there is a battery cell 1 at the end of the ramp surface 2-1, the PLC program receives the signal that there is a battery cell 1 at the end of the ramp surface 2-1. The PLC program controls the first cylinder 4 to work, and the first cylinder 4 drives the battery cell 1 located at the end of the ramp surface 2-1 to move forward in a straight line.

[0039] The first cylinder 4 can be a rodless cylinder. An L-shaped push plate can be installed on the rodless cylinder. The push plate contacts the side of the battery cell. The push plate needs to be covered with a soft material, such as silicone, to prevent scratching the battery cell. A U-shaped groove is provided at the end of the ramp surface 2-1. When the battery cell 1 is located in the U-shaped groove, the L-shaped push plate connected to the drive end of the rodless cylinder pushes the battery cell 1 forward.

[0040] A horizontal mounting plate 5 is provided on one side of one of the limiting plates 2-2. A mounting bracket is provided on the horizontal mounting plate 5, and a cell rotation drive device 6 is mounted on the mounting bracket. The cell rotation drive device 6 includes a drive motor 6-1 and a drive roller. The drive roller includes a driving roller 6-2 and a driven roller 6-3, which are movably connected to the mounting component 5-1 on the horizontal mounting plate 5 via bearings. When the driving roller 6-2 and driven roller 6-3 are close to the notch on one of the limiting plates 2-2, the first cylinder 4 pushes the cell 1 to move above the driving roller 6-2 and driven roller 6-3. Figure 4 As shown, the driving roller 6-2 and the driven roller 6-3 receive the battery cell 1.

[0041] like Figure 5 and Figure 6 As shown, a vertical mounting plate 7 is provided on one side of the horizontal mounting plate 5. An adhesive tape applicator 8 is provided on the vertical mounting plate 7. The adhesive tape applicator includes an adhesive tape tray 8-1, a guide roller cylinder 8-2, two guide rollers 8-3, an adhesive tape pressing cylinder 8-4, an adhesive tape receiving plate 8-5, a side plate 8-5-1, a U-shaped adhesive tape limiting component 8-6, an adhesive tape pulling cylinder 8-7, a pressing clamp 8-8, a pressing clamp cylinder 8-9, and a slide rail 8-10.

[0042] The adhesive tape roll is mounted on a cylindrical rod on the adhesive tape reel. The adhesive tape roll can rotate freely on the adhesive tape reel to release the adhesive tape 9, as shown. Figure 6As shown, the guide roller 8-3 has a through hole for the adhesive tape 9 to pass through. The adhesive tape receiving plate 8-5 is a long, horizontal plate used to receive the adhesive tape 9. A vertical side plate 8-5-1 is connected to the side of the adhesive tape receiving plate 8-5. The adhesive tape receiving plate 8-5 and the side plate 8-5-1 are L-shaped. The side of the side plate 8-5-1 facing the adhesive tape receiving plate 8-5 is the front. A pressing clamp cylinder 8-9 is installed on the front of the side plate 8-5-1. The driving end of the pressing clamp cylinder 8-9 is connected to the pressing clamp 8-8. When the PLC controls the pressing clamp cylinder 8-9 to work, the end of the pressing clamp 8-8 can press the adhesive tape 9 onto the adhesive tape receiving plate 8-5, or the end of the pressing clamp 8-8 can be moved away from the adhesive tape receiving plate 8-5. A long, narrow through hole 7-2 is provided on the vertical mounting plate 7 at a position relative to the adhesive tape receiving plate 8-5. A flat plate can be connected to the front side of the vertical mounting plate 7. A vertical slide rail 8-10 is provided on the flat plate, and the slide rail 8-10 is parallel to the vertical mounting plate 7. A U-shaped slider 8-5-2 is installed on the back of the side plate 8-5-1. The top of the slide rail 8-10 is located in the opening of the U-shaped slider 8-5-2. The slide rail 8-10 and the U-shaped slider 8-5-2 are in clearance fit. An adhesive tape pulling cylinder 8-7 is provided on the back of the vertical mounting plate 7. The driving end of the adhesive tape pulling cylinder 8-7 passes through the through hole 7-2 and is connected to the top surface of the side plate 8-5-1. In the initial state, with the pressure cylinder 8-4 and the pressing clamp 8-8 not pressed down, the adhesive tape 9 can be manually passed through the guide roller 8-3, the adhesive tape receiving plate 8-5, and the U-shaped adhesive tape limiting member 8-6, ensuring that the front end of the adhesive tape 9 always extends beyond the adhesive tape receiving plate 8-5. When the adhesive tape 9 is on the adhesive tape receiving plate 8-5, the pressure cylinder 8-4 is not pressed down, the pressing clamp 8-8 is pressed down, and the adhesive tape pulling cylinder 8-7 is working, the adhesive tape pulling cylinder 8-7 drives the slider 8-5-2 to move along the slide rail 8-10. When the slider 8-5-2 moves along the slide rail 8-10 towards the drive roller 6, the adhesive tape receiving plate 8-5 and the adhesive tape 9 move synchronously towards the drive roller 6, thereby causing the front end of the adhesive tape 9 to move above the drive roller.

[0043] U-shaped adhesive tape limiting component 8-6 is installed on the adhesive tape receiving plate 8-5, and the U-shaped adhesive tape limiting component 8-6 and the vertical mounting plate 7 are located on opposite sides of the adhesive tape receiving plate 8-5. When the adhesive tape 9 is on the adhesive tape receiving plate 8-5, the adhesive tape 9 is located at the opening of the U-shaped adhesive tape limiting component 8-6, and the movement of the adhesive tape 9 is limited by the U-shaped adhesive tape limiting component 8-6. The guide roller 8-3 is installed on the vertical mounting plate 7 through the mounting base. The guide roller 8-3 can be designed with a pattern such as a diamond pattern to enhance friction. One of the guide rollers 8-3 is connected to the drive end of the guide roller cylinder 8-2. When the guide roller cylinder 8-2 is working, the guide roller 8-3 connected to the guide roller cylinder 8-2 rotates. The rotation of the guide roller 8-3 drives the adhesive tape 9 forward. The guide roller 8-3 plays a guiding role. It is preferable to set two guide rollers 8-3. When the adhesive tape 9 is positioned on the guide roller 8-3 and the adhesive tape receiving plate 8-5, the guide roller cylinder 8-2 pulls the adhesive tape 9 to move. The adhesive tape pressing cylinder 8-4 is mounted on the vertical mounting plate 7, located above one of the guide rollers 8-3. After the adhesive tape 9 is pasted around the end of the battery cell 1, it needs to be cut. During cutting, the front end of the adhesive tape pressing cylinder 8-4 presses against the guide roller to prevent the adhesive tape from shifting during cutting. The contact surface between the adhesive tape pressing cylinder 8-4 and the adhesive tape 9 is typically made of silicone or polyurethane to avoid damaging the surface of the adhesive tape 9. Initially, the adhesive tape 9 can be manually pulled through the guide roller 8-3 and positioned on the adhesive tape receiving plate 8-5. Subsequently, the adhesive tape 9 can be moved by pulling the adhesive tape cylinder 8-7.

[0044] like Figure 6As shown, a clamping device 10 is installed on the vertical mounting plate 7. The clamping device 10 includes a pressing cylinder 10-1. The pressing cylinder 10-1 is installed on the vertical mounting plate 7 through a mounting bracket. Preferably, two pressing cylinders 10-1 are provided. The driving end of each pressing cylinder 10-1 is connected to a pressing roller 10-2. When the battery cell 1 is located on the driving roller 6-2 and the driven roller 6-3, the PLC controls the pressing cylinder 10-1 to work. The pressing cylinder 10-1 drives the pressing roller 10-2 to move downward, so that the pressing roller 10-2 contacts the battery cell 1. A magnetic inductive switch is usually installed on the cylinder. When the magnetic inductive switch on the lower cylinder 10-1 senses that the drive end of the lower cylinder 10-1 has moved to its maximum stroke, the PLC controls the drive motor 6-1 to work. The drive motor 6-1 drives the active roller 6-2 to rotate through the synchronous belt. The driven roller 6-3 achieves friction transmission with the active roller 6-2. The cylindrical battery cell 1 is placed on the active roller 6-2 and the driven roller 6-3. The motor drives the drive roller to rotate through the synchronous belt pulley, thereby driving the cylindrical battery cell 1 to rotate. Since the adhesive paper 9 is between the pressing roller 10-2 and the battery cell 1, when the pressing roller 10-2 moves downward, the adhesive paper 9 is pressed down by the pressing roller 10-2 and pasted to the end of the battery cell 1. Since the battery cell 1 is rotating, the adhesive paper 9 is pasted around the end of the battery cell 1 for 1 circumference. The pressing cylinder 10-1 drives the pressing roller 10-2 to press onto the battery cell 1. The battery cell rotation drive device 6 drives the battery cell 1 to rotate. The pressing device 10 fixes the battery cell 1, preventing slippage in the drive transmission. The pressing roller 10-2 is movably mounted on the receiving bracket. When the battery cell 1 rotates, the pressing roller 10-2 can rotate synchronously. Only during the adhesive tape application stage will both pressing rollers 10-2 press onto the battery cell 1 simultaneously. When the adhesive tape is being rolled up, the pressing roller 10-2 closer to the adhesive tape roll-up device 12 is lifted by the cylinder and does not press onto the battery cell 1, while the pressing roller 10-2 farther away from the adhesive tape roll-up device 12 presses onto the battery cell 1. In one specific embodiment, the lengths of the two pressing rollers 10-2 can also be designed so that when the adhesive tape is being rolled up, both pressing rollers 10-2 press on the battery cell 1. The length of the pressing roller 10-2 closest to the adhesive tape winding device 12 only needs to be sufficient to avoid the working space of the adhesive tape winding device 12.

[0045] After cell 1 rotates one and a half times, it indicates that the adhesive tape 9 has been successfully applied around the end of cell 1. The rotation angle of drive motor 6-1 can be set to a preset angle. Then, cell 1 will rotate one and a half times. Figure 9As shown, a cutting cylinder 11 is mounted on the vertical mounting plate 7 via a bracket. The drive end of the cutting cylinder is connected to a cutter 11-1. When the PLC receives a signal from the drive motor 6-1 to rotate at a preset angle, the PLC controls the cutting cylinder 11 to work, causing the cutter 11-1 to move downwards to cut the adhesive paper 9. In this utility model, the adhesive paper pulling cylinder 8-2 works according to a set frequency. When the drive motor 6-1 works to rotate the battery cell 1 and apply the adhesive paper, the rotation of the battery cell 1 can drive the adhesive paper 9 forward. When the drive motor 6-1 is working, the adhesive paper pulling cylinder 8-2 can be stopped by the PLC control.

[0046] like Figure 10 As shown, after the adhesive tape 9 has been pasted around the end of the battery cell 1, part of the adhesive tape 9 protrudes from the end of the battery cell 1. It is necessary to tuck the part of the adhesive tape 9 that protrudes from the end of the battery cell 1, that is, to stick the part of the adhesive tape 9 that protrudes from the end of the battery cell 1 onto the end face of the battery cell, that is, to stick it onto the top surface or bottom surface of the cylindrical battery cell 1.

[0047] The adhesive tape applicator 8, the cutting cylinder 11, and the clamping device 10 are sequentially installed on the vertical mounting plate 7. For example... Figure 1 , Figure 7 , Figures 11 to 13 As shown, a tape retracting device 12 is installed on the workbench. An opening 7-1 is provided on the vertical mounting plate 7, which enables communication between the two sides of the vertical mounting plate 7. The opening 7-1 corresponds to the position of the drive roller and the battery cell 1 on the drive roller, and the opening 7-1 also corresponds to the position of the tape retracting device 12. One end of the tape retracting device 12 can pass through the opening 7-1 to contact the battery cell 1.

[0048] The adhesive tape retracting device 12 includes an adhesive tape retracting cylinder 12-1, a support plate 12-2 connected to the drive end of the adhesive tape retracting cylinder 12-1, an adhesive tape pressing cylinder 12-3 located on the support plate 12-2, an adhesive tape pressing member 12-4 connected to the drive end of the adhesive tape pressing cylinder 12-3, and a retracting tapered member 12-5 connected to the end of the support plate 12-2 facing the battery cell 1.

[0049] like Figures 12 to 13 As shown, the adhesive tape pressing component 12-4 is connected to the drive end of the adhesive tape pressing cylinder 12-3 via a bracket. The adhesive tape pressing component 12-4 includes a circular surface 12-4-1, with a through hole in the center to reduce interference and weight. Multiple planar pressing tabs 12-4-2 are evenly spaced along the circumference of the circular surface 12-4-1, and the circular surface 12-4-1 and the multiple pressing tabs 12-4-2 are on the same plane. In a preferred embodiment, six pressing tabs 12-4-2 can be evenly spaced along the circumference of the circular surface 12-4-1.

[0050] like Figure 13As shown, the conical member 12-5 is connected to the end of the support plate 12-2 facing the battery cell 1 via a bracket. The conical member 12-5 includes an annular ring 12-5-1. When the adhesive tape at the end of the battery cell 1 is trimmed, the through hole in the middle of the annular ring 12-5-1 is used to accommodate the end of the battery cell 1 with the adhesive tape 9. Multiple flanges 12-5-2 are evenly spaced on the annular ring 12-5-1. The flanges 12-5-2 and the battery cell 1 are located on opposite sides of the annular ring 12-5-1. Each flange forms a preset angle with the surface of the annular ring 12-5-1. The preset angle can be 30°-60°. The annular ring 12-5-1 and the multiple flanges 12-5-2 form a cone. As a preferred embodiment, six flanges 12-5-2 can be evenly spaced on the annular ring 12-5-1, forming a cone. The number of pressing tabs 12-4-2 and flanges 12-5-2 are equal. In the initial state, the adhesive tape pressing tabs 12-4 and the inward tapered tabs 12-5 are spaced apart by a preset distance. There are gaps between the multiple spaced flanges 12-5-2. When the part of the adhesive tape 9 protruding from the end of the battery cell 1 is pressed and attached to the end face of the battery cell by the pressing tabs 12-4-2, each pressing tab 12-4-2 is located in the gap between two flanges 12-5-2. Each pressing tab 12-4-2 is attached with sponge adhesive, so that the junction between the adhesive tape 9 and the end face of the battery cell is more tightly adhered.

[0051] When the adhesive tape 9 protruding from the end of the battery cell 1 is attached to the end face of the battery cell by the adhesive tape retraction device 12, the adhesive tape retraction cylinder 12-1 extends, and the retraction cone 12-5 is coaxial with the battery cell 1. The retraction cone 12-5 is pushed forward, causing the adhesive tape 9 protruding from the end face of the battery cell 1 to enter the inside of the retraction cone 12-5, thereby causing the adhesive tape 9 protruding from the end face of the battery cell 1 to bend inward and retract. After the adhesive tape is retracted, the adhesive tape pressing device 12-4 is pushed forward, and each pressing piece 12-4-2 is located in the gap between the two flanges 12-5-2, pressing the portion of the adhesive tape 9 protruding from the end of the battery cell 1 onto the end face of the battery cell. In this utility model, the adhesive tape pressing part 12-4 is toothed and does not interfere with the inward conical part 12-5. The toothed pressing part is covered with sponge adhesive, which makes the adhesive tape adhere more firmly to the end face of the battery cell when it extends and presses. After the adhesive tape pressing part 12-4 is pressed, it retracts. The drive motor 6-1 works to drive the battery cell 1 to rotate and change the pressing position of the adhesive tape. The adhesive tape pressing part 12-4 presses again. After pressing, the adhesive tape pressing part 12-4 and the inward conical part 12-5 retract.

[0052] The drive roller 6-2 is movably connected to the mounting piece 5-1 on the horizontal mounting plate 5 via a bearing. For example... Figure 1 , Figure 11 , Figure 14 and Figure 15As shown, a vertical support 5-2 is connected to each side of the bottom surface of the mounting component 5-1. The two ends of the two vertical support components 5-2 are hinged to the hinge shaft 5-3. The hinge shaft 5-3 is located on two support seats 5-4 on the horizontal mounting plate 5, and the two support seats 5-4 provide support for the hinge shaft 5-3.

[0053] This utility model also includes a feeding device 13, which includes a feeding cylinder 13-1 and a battery cell recovery part 13-2. The driving end of the feeding cylinder 13-1 is connected to the side or bottom of the mounting component 5-1. The battery cell recovery part 13-2 is in the shape of a slide, with an inclined surface at the top and a flat surface at the bottom. The battery cell recovery part 13-2 is supported on the worktable by multiple support rods and is located on the side of the drive roller.

[0054] After the adhesive tape pressing part 12-4 and the inward conical part 12-5 are retracted, the PLC controls the feeding cylinder 13-1 to work. The feeding cylinder 13-1 extends, and the vertical support part 5-2 and the hinge shaft 5-3 are connected. The extension of the feeding cylinder 13-1 causes the vertical support part 5-2 to drive the mounting part 5-1 to rotate around the hinge shaft, causing the mounting part 5-1, the drive roller and the battery cell to flip over as a whole. The battery cell 1 is fed out along the sliding battery cell recycling part 13-2. After feeding out, the feeding cylinder 13-1 retracts, driving the mounting part 5-1 back to its original horizontal position. The battery cell is then manually removed from the battery cell recycling part 13-2.

[0055] This utility model's automatic battery cell labeling mechanism includes a feeding device 2, a battery cell rotation drive device 6, a battery cell pressing device 10, an adhesive tape retracting device 12, and a feeding device 13. The adhesive tape retracting device 12 includes an adhesive tape pressing component 12-4 and a retracting conical component 12-5. After the adhesive tape is pasted onto the head of the battery cell and cut, the battery cell is placed on the battery cell rotation drive device 6, and the battery cell pressing device 10 presses the battery cell. The adhesive tape retracting device 12 extends out, and the retracting conical component 12-5 is coaxial with the battery cell. The retracting conical component 12-5 pushes forward to bend the adhesive tape extending from the end face of the battery cell. After the adhesive tape is bent, the adhesive tape pressing component 12-4 extends out, and the adhesive tape presses... The pressing part 12-4 is toothed and does not interfere with the inward tapered part 12-5. The toothed pressing part is covered with sponge adhesive. When it extends to press, it makes the adhesive paper adhere more firmly to the end face of the battery cell. After the adhesive paper pressing part 12-4 is pressed, it retracts. The battery cell rotation drive device 6 drives the battery cell to rotate, changing the position of the adhesive paper pressing part. The adhesive paper pressing part 12-4 pressing mechanism presses again. After pressing, the adhesive paper retraction device 12 retracts, the battery cell pressing device 10 lifts up, and the unloading device 13, including the unloading cylinder 13-1, extends to make the battery cell 1 tilt and slide down, completing the unloading. After unloading, the entire mechanism retracts to return to its original state, ready for the next adhesive application. This process is repeated.

[0056] In this invention, when the battery cell 1 is located on the drive roller, the adhesive tape 9 is above the drive roller and the battery cell. The pressing roller 10-2 presses down, pressing the adhesive tape 9 onto the end of the battery cell 1. The pressing clamp 8-8 is released, and the battery cell 1 rotates. After the battery cell 1 rotates one and a half times, the adhesive tape 9 is pasted around the end of the battery cell 1. Then, the pressing clamp 8-8 and the adhesive tape pressing cylinder 8-4 press down, and the cutter 11-1 cuts the adhesive tape. After the adhesive tape is cut, the adhesive tape pressing cylinder 8-4 moves up, and the adhesive tape pulling cylinder 8-7 drives the slider 8-5-2 to retract. During the retraction, the pressing clamp 8-8 is in a clamping state. After the adhesive tape pulling cylinder 8-7 retracts, the guide roller cylinder 8-2 operates, pushing the guide roller 8-3 to rotate to pull the adhesive tape for storage. When the adhesive tape on the adhesive tape tray 8-1 is pulled apart for storage, the adhesive tape pressing cylinder 8-4 presses down on the adhesive tape to complete the storage of the adhesive tape. In this invention, when the adhesive paper pulling cylinder 8-7 is working, it drives the slider 8-5-2 to move along the slide rail 8-10 toward the drive roller 6. At the same time, the adhesive paper receiving plate 8-5 and the adhesive paper 9 move toward the drive roller 6. When the adhesive paper pulling cylinder 8-7 reaches its maximum stroke, the front end of the adhesive paper 9 moves above the drive roller. The battery cell 1 rotates so that when the adhesive paper is pasted at the front end of the battery cell, the pressing clamp 8-8 is released. The rotation of the battery cell 1 drives the front end of the adhesive paper 9 to move forward, thereby realizing the forward movement of the stored adhesive paper, so that the front end of the adhesive paper 9 is above the drive roller.

[0057] The specific method for automatically applying adhesive tape to cylindrical battery cells using the mechanism of this utility model is as follows:

[0058] In the initial state, the manual puller pulls the adhesive paper 9 above the drive roller, the mechanism starts, and the manual places the battery cell 1 on the feeding device 2. The battery cell 1 slides down the slope 2-1.

[0059] When cell 1 slides to the bottom of slope 2-1, the reflective photoelectric sensor detects that there is a cell at the bottom of slope 2-1. After receiving the signal that there is a cell at the bottom of slope 2-1, the PLC program controls the first cylinder 4 to push cell 1 onto the driving roller 6-2 and the driven roller 6-3. When the driving end of the first cylinder 4 is at its maximum stroke, cell 1 is completely located on the driving roller 6-2 and the driven roller 6-3.

[0060] The magnetic induction switch on the first cylinder 4 can sense that the drive end of the first cylinder 4 is at its maximum stroke. When the PLC program receives the signal that the drive end of the first cylinder 4 is at its maximum stroke, it controls the first cylinder 4 to return to its original position and controls the pressing cylinder 10-1 to work. The adhesive paper pulling cylinder 8-7 works so that the front end of the adhesive paper 9 is above the drive roller and the battery cell, and between the battery cell and the pressing cylinder 10-1. The working of the pressing cylinder 10-1 drives the pressing roller 10-2 to move downward. The pressing roller 10-2 presses down so that the adhesive paper 9 sticks to the end of the battery cell 1. The magnetic induction switch on the pressing cylinder 10-1 senses that the drive end of the pressing cylinder 10-1 has reached its maximum stroke.

[0061] After receiving a signal that the drive end of the pressing cylinder 10-1 has reached its maximum stroke, the PLC controls the drive motor 6-1 to work. The drive motor 6-1 drives the drive roller and the battery cell 1 to rotate. After the drive motor 6-1 rotates to a preset angle, the adhesive tape 9 is pasted around the end of the battery cell 1.

[0062] When the PLC receives the signal that the drive motor 6-1 rotates to a preset angle, it controls the drive motor 6-1 to stop working and controls the cutting cylinder 11 to drive the cutter 11-1 to move downward. When the drive end of the cutting cylinder 11 reaches the maximum stroke, the cutter 11-1 cuts the adhesive paper 9. The magnetic induction switch on the cutting cylinder 11 can sense whether the drive end of the cutting cylinder 11 has reached the maximum stroke.

[0063] When the PLC receives a signal that the cutting cylinder 11 has reached its maximum stroke, it controls the cutting cylinder 11 to return to its original position and controls the tape retraction cylinder 12-1 to operate. The operation of the tape retraction cylinder 12-1 drives the retraction cone 12-5 towards the battery cell 1. When the driving end of the tape retraction cylinder 12-1 reaches its maximum stroke, the tape 9 at the end of the battery cell 1 enters the retraction cone 12-5, causing the tape extending from the battery cell end face to bend inward. The magnetic induction switch on the tape retraction cylinder 12-1 can detect whether the driving end of the tape retraction cylinder 12-1 has reached its maximum stroke.

[0064] When the PLC receives a signal that the drive end of the adhesive tape retracting cylinder 12-1 has reached its maximum stroke, it controls the adhesive tape pressing cylinder 12-3 to operate. The adhesive tape pressing cylinder 12-3 drives the adhesive tape pressing piece 12-4 to move towards the battery cell 1. Each pressing piece 12-4-2 is located in a gap between the two flanges 12-5-2. When the drive end of the adhesive tape pressing cylinder 12-3 reaches its maximum stroke, the pressing piece 12-4-2 presses the portion of the adhesive tape 9 protruding from the end of the battery cell 1 onto the end face of the battery cell. The magnetic induction switch on the adhesive tape pressing cylinder 12-3 can detect whether the drive end of the adhesive tape pressing cylinder 12-3 has reached its maximum stroke.

[0065] When the PLC receives a signal that the drive end of the adhesive tape pressing cylinder 12-3 has reached its maximum stroke, it controls the adhesive tape pressing cylinder 12-3 to return to its original position and controls the drive motor 6-1 to rotate by a preset angle, so that the battery cell 1 rotates by a preset angle. When the PLC receives a signal that the drive motor 6-1 has rotated by a preset angle, it controls the drive motor 6-1 to stop working and controls the adhesive tape pressing cylinder 12-3 to work again, so that after changing the pressing position, the pressing plate 12-4-2 presses the adhesive tape protruding from the end of the battery cell 1 again. When the PLC receives a signal that the drive end of the adhesive tape pressing cylinder 12-3 has reached its maximum stroke again, it controls the adhesive tape pressing cylinder 12-3 to return to its original position and controls the pressing cylinder 10-1 to return to its original position.

[0066] After receiving the signal for the return of the pressing cylinder 10-1, the PLC controls the feeding cylinder 13-1 to operate. When the driving end of the feeding cylinder 13-1 reaches its maximum stroke, the feeding cylinder 13-1 causes the mounting part 5-1 to tilt to the side, allowing the battery cell 1 to slide down and be retrieved along the battery cell recovery section 13-2. The magnetic induction switch on the feeding cylinder 13-1 can sense whether the driving end of the feeding cylinder 13-1 has reached its maximum stroke.

[0067] When the PLC receives a signal that the drive end of the unloading cylinder 13-1 has reached its maximum stroke, it controls the unloading cylinder 13-1 to return to its original position.

[0068] In this invention, initially, the adhesive tape 9 is manually pulled above the drive roller. In subsequent stages, the adhesive tape pulling cylinder 8-7 moves the front end of the adhesive tape 9 above the drive roller. These steps are repeated to achieve the feeding of cylindrical battery cells, automatic adhesive tape application, automatic edge trimming of the adhesive tape protruding from the battery cell end, and battery cell unloading.
