Description

Technical Field

[0001] This utility model belongs to the technical field of coating device technology, specifically relating to a coating device for the head of a battery cell. Background Technology

[0002] After the cylindrical battery cell is wound, the electrodes at both ends of the cell are exposed. This may affect the performance and quality of the cell during subsequent processing. Therefore, insulating tape is needed to cover the exposed electrodes to ensure the quality of the battery cell.

[0003] Existing cell-head adhesive coating devices typically use a displacement module to move the adhesive-gripping claws holding the cell to the adhesive outlet. A follower then drives a coating roller to press down the adhesive paper, securing it to the cell head. The follower and displacement module then move the coating rollers and gripping claws to the desired length, and a rotation module drives the gripping claws to rotate, thus rotating the cell and completing the coating process. However, this method is prone to problems. If the adhesive paper tension fluctuates or disappears during coating, some adhesive paper may loosen and adhere to the cell, leading to wrinkles and reducing its practicality. Utility Model Content

[0019] In summary, this utility model has at least the following advantages:

[0020] The battery cell head coating device provided by this utility model, when the adhesive paper is conveyed from right to left, the lifting component moves the battery cell closer to the adhesive area, so that the battery cell is located between the roller unit and the drive spindle. After the adhesive paper is pulled to the battery cell, the adhesive side of the adhesive paper faces down. The lifting component moves the roller unit upward, so that the lifting component and the drive spindle press the adhesive side of the adhesive paper onto the battery cell. Subsequently, the coating driver works, and the drive spindle rotates clockwise, thereby driving the battery cell to roll on the roller unit. That is, under the driving action of the drive spindle, the battery cell and the rollers in the roller unit roll synchronously under the action of friction, so that the adhesive paper can be continuously pressed against and wound on the battery cell. Since the drive spindle and the roller unit apply a certain amount of pressure to the battery cell and the adhesive paper during and after winding, and the rollers of the roller unit roll against the adhesive paper, the adhesive paper can be firmly wound on the head of the battery cell, thereby effectively preventing the adhesive paper from loosening and sticking to the battery cell when the adhesive paper pressure fluctuates or disappears, thus avoiding wrinkling. Therefore, the cell head coating device of this application is more practical. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only some embodiments of this utility model, not all embodiments.

[0035] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0036] In the following embodiments and accompanying drawings, reference is made to Figure 1 The coordinate system is defined with the arrow pointing to the right on the X-axis, the arrow pointing to the front on the Y-axis, and the arrow pointing to the top on the Z-axis.

[0037] Example 1:

[0038] like Figures 1 to 4As shown, this embodiment provides a battery cell head coating device 10, including: a frame 400; a lifting mechanism 200, including a positioning component 220 and a lifting component 210 for driving the positioning component 220 to rise or fall, the positioning component 220 including a positioning frame 221 and a roller unit 222 for forming a V-shaped rolling support for the periphery of the battery cell 510, the output end of the lifting component 210 is connected to the positioning frame 221, and the roller unit 222 is disposed on the positioning frame 221; and a coating mechanism 300, including a coating driver 320 and a drive spindle 310 for driving the battery cell 510 on the roller unit 222 to rotate, the coating driver 320 is connected to the frame 400, the output end of the coating driver 320 is connected to the drive spindle 310, and the drive spindle 310 abuts against and drives the battery cell 510 to rotate on the roller unit 222 to wrap the head of the battery cell 510 with coating.

[0039] Specifically, a coating mechanism 300 is installed on the front side of the frame 400, and a lifting mechanism 200 is located below the coating mechanism 300. A conveyor line 500 transports the battery cell 510 along the X-axis and is located between the lifting mechanism 200 and the coating mechanism 300. A lifting assembly 210 supports a positioning frame 221 and moves the positioning frame 221 upwards. The positioning frame 221 can be, but is not limited to, concave, and the conveyor line 500 passes through the positioning frame 221. A roller unit 222 is installed on the positioning frame 221 and supports the left and right sides of the battery cell 510. A coating driver 320 drives the drive spindle 310 to rotate on the frame 400. The coating driver 320 can be, but is not limited to, a motor. The method by which a motor drives the drive spindle 310 to rotate is known to those skilled in the art and is feasible; therefore, it will not be described in detail in this embodiment.

[0040] It is worth noting that when the adhesive tape 111 is conveyed from right to left, the lifting assembly 210 moves the battery cell 510 closer to the adhesive surface, so that the battery cell 510 is positioned between the roller unit 222 and the drive spindle 310, pulling the adhesive tape 111 close to the battery cell 510 with the adhesive side of the adhesive tape 111 facing down. The lifting assembly 210 moves the roller unit 222 upward, so that the lifting assembly 210 and the drive spindle 310 press against the adhesive side of the adhesive tape 111 on the battery cell 510. Subsequently, the adhesive wrapping driver 320 operates, and the drive spindle 310 rotates clockwise, thereby causing the battery cell 510 to roll on the roller unit 222, that is, on the drive spindle 310. Driven by shaft 310, the battery cell 510 and the rollers in roller unit 222 roll synchronously under friction, thereby continuously pressing and winding the adhesive tape 111 onto the battery cell 510. Because the drive shaft 310 and roller unit 222 apply a certain amount of pressure to the battery cell 510 and the adhesive tape during and after winding, and the rollers of roller unit 222 roll and press against the adhesive tape 111, the adhesive tape 111 can be securely wound around the head of the battery cell 510. This effectively prevents the adhesive tape 111 from loosening and sticking to the battery cell 510 when the tension of the adhesive tape 111 fluctuates or disappears, thus avoiding wrinkling. Therefore, the battery cell head adhesive wrapping device 10 of this application is more practical.

[0041] To facilitate the support of the battery cell 510 by the roller unit 222, such as Figure 2 and Figure 3 As shown, in some embodiments, the roller unit 222 includes at least two rollers, which are disposed opposite to each other on both sides of the positioning frame 221.

[0042] Specifically, two rollers are arranged side-by-side on the left and right sides of the positioning frame 221, and the gap between them is set to correspond to the width of the battery cell 510, such as being slightly smaller than the width of the battery cell 510, so that the left and right sides of the battery cell 510 can be supported by the rollers on the left and right sides. (Reference) Figure 1 The number of rollers can be selected, but is not limited to, four. The two front rollers are rotatably mounted on the front side of the positioning frame 221, and the two rear rollers are rotatably mounted on the rear side of the positioning frame 221. Thus, the four rollers are arranged in a square on the positioning frame 221, and the conveyor line 500 is located between the front and rear rollers to facilitate the component clamping the battery cell 510 onto the roller unit 222. When the drive spindle 310 rotates clockwise, the battery cell 510 rotates counterclockwise under the action of friction, causing the two front and rear rollers on the left to rotate clockwise, and subsequently causing the two front and rear rollers on the right to rotate clockwise. This ensures that the adhesive tape 111 can fully contact the battery cell 510, resulting in better flatness of the adhesive tape 111 after coating.

[0043] It is understood that the number and arrangement of rollers in roller unit 222 are based on actual production needs and are not limited here. It is only necessary to ensure that they can provide V-shaped support for the periphery of battery cell 510 and rotate synchronously with the rotation of battery cell 510. For example, the number of rollers can be set to two, the rollers can be set to cylindrical, and the two rollers can rotate on the left and right sides of positioning frame 221 respectively.

[0044] Example 2

[0045] This embodiment is a further implementation of Embodiment 1, such as... Figure 1 and Figure 2 As shown, in this embodiment, the lifting mechanism 200 further includes a clamping unit 223. The clamping unit 223 includes two three-axis cylinders 2231, a front abutment member 2232 and a rear abutment member 2233. The two three-axis cylinders 2231 are installed on the other two sides of the positioning frame 221. The output end of one three-axis cylinder 2231 is connected to the front abutment member 2232, and the output end of the other three-axis cylinder 2231 is connected to the rear abutment member 2233.

[0046] Specifically, the lifting assembly 210 drives the clamping unit 223 to clamp the battery cell 510. The clamping unit 223 is used to clamp the front and rear ends of the battery cell 510. The three-axis cylinder 2231 is used to drive the corresponding component to move along the X-axis and Y-axis directions. One three-axis cylinder 2231 is installed on the front side of the positioning frame 221 and its output end is connected to the front abutment 2232. The other three-axis cylinder 2231 is installed on the rear side of the positioning frame 221 and its output end is connected to the rear abutment 2233. The front abutment 2232 is located between the two rollers on the front side. The front abutment 2232 can be selected from, but is not limited to, a rotating pressure head. The rear abutment 2233 is located between the two rollers on the rear side. The rear abutment 2233 can be selected from, but is not limited to, a pressure head. After the battery cell 510 is transported to the designated position via the conveyor line 500, the piston rod of the front three-axis cylinder 2231 retracts and the piston rod of the rear three-axis cylinder 2231 extends, so as to push the rotating pressure head and the pressure head to clamp the battery cell 510 respectively.

[0047] Furthermore, a retaining rotating member is provided on one of the adjacent ends of the front retaining member 2232 and the rear retaining member 2233 respectively.

[0048] Specifically, the rotating abutment can be, but is not limited to, bearings. Bearings are fitted onto the ends of the front abutment 2232 and the rear abutment 2233 near the battery cell 510. Thus, during the coating process of the battery cell 510, the rotating pressure head and the pressure head abut against the front and rear ends of the battery cell 510 via corresponding bearings. That is, the battery cell 510 is limited by the bearings on both sides, and the bearings can rotate with the battery cell 510 as it rotates. This prevents damage to the battery cell 510 from the rotating pressure head and the pressure head due to their fixed clamping action, and also prevents the ends of the battery cell 510 from shifting due to the absence of limiting components.

[0049] To facilitate the use of the lifting assembly 210, such as Figure 2 As shown, in some embodiments, the lifting assembly 210 includes a lifting driver 211, the output of which is connected to the positioning frame 221.

[0050] Specifically, the lifting driver 211 may be, but is not limited to, a slide cylinder, which is mounted on the base. When the rotating pressure head clamps the battery cell 510, the piston rod of the slide cylinder extends, pushing the positioning frame 221 upward to lift the clamping unit 223, thereby delivering the battery cell 510 to the glue-coating position.

[0051] Example 3

[0052] This embodiment is a further implementation of embodiment 1 or 2, such as... Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, the cell head coating device 10 further includes a coating feeding mechanism 100. The coating feeding mechanism 100 includes an unwinding reel 110, a plurality of dispensing rollers 120, and a coating clamping assembly 130. The unwinding reel 110 and the plurality of dispensing rollers 120 are mounted on the frame 400. The coating clamping assembly 130 includes a coating clamping drive unit 131 and a coating clamping unit 132. The output end of the coating clamping drive unit 131 is connected to the coating clamping unit 132 to drive the coating clamping unit 132 to move the adhesive paper 111 to the coating position.

[0053] Specifically, the unwind reel 110 is installed at the upper end of the frame 400, and adhesive tape 111 is wound on the unwind reel 110. Multiple dispensing rollers 120 are located on the right side of the frame 400, and each dispensing roller 120 guides the adhesive tape 111 outwards. The adhesive clamping assembly 130 is located on the left side of the frame 400. The adhesive clamping unit 132 clamps the adhesive tape 111 flowing out of the unwind reel 110, and the adhesive tape 111 protrudes slightly from the left side of the adhesive clamping unit 132. The adhesive clamping drive unit 131 drives the adhesive clamping unit 132 to convey the adhesive tape 111 to the battery cell 510. The adhesive tape 111 is fed out through the glue dispensing roller 120 via the unwinding reel 110. The glue clamping drive unit 131 drives the glue clamping unit 132 to clamp the adhesive tape 111 and send the adhesive tape 111 between the drive spindle 310 and the battery cell 510. During the glue wrapping process, the glue clamping unit 132 releases the adhesive tape 111 and the glue clamping drive unit 131 drives the glue clamping unit 132 to return to its original position.

[0054] To facilitate the driving of the clamping unit 132 by the clamping drive unit 131, such as Figure 3 and Figure 4 As shown, in some embodiments, the adhesive clamping drive unit 131 includes an X-axis driver 1311, an X-axis slide rail 1312, a mounting base 1313, a Z-axis driver 1314, a Z-axis slide rail 1315, and a mounting plate 1316. The mounting base 1313 is slidably disposed on the X-axis slide rail 1312. The output end of the X-axis driver 1311 is connected to the mounting base 1313. The Z-axis slide rail 1315 and the Z-axis driver 1314 are connected to the mounting base 1313. The mounting plate 1316 is slidably disposed on the Z-axis slide rail 1315, and the output end of the Z-axis driver 1314 is connected to the mounting plate 1316. The adhesive clamping unit 132 is disposed on the mounting plate 1316.

[0055] Specifically, a concave notch is provided on the left side of the frame 400. The X-axis driver 1311 is installed on the rear side of the frame 400. The X-axis driver 1311 can be, but is not limited to, a cylinder. The X-axis slide rail 1312 is installed on the rear side of the frame 400 and can be configured as two parallel ones. The two ends of the mounting base 1313 slide on the X-axis slide rail 1312 via sliders. The Z-axis slide rail 1315 passes through the concave notch and is installed on the mounting base 1313. The Z-axis driver 1314 is fixedly connected to the mounting base 1313 and is located on one side of the Z-axis slide rail 1315. The Z-axis driver 1314 can be, but is not limited to, a cylinder. The mounting plate 1316 slides on the Z-axis slide rail 1315, and the clamping unit 132 is installed on the mounting plate 1316. Thus, during the conveying of the clamping unit 132, the X-axis driver 1311 drives the mounting base 1313 to slide to the left on the X-axis slide rail 1312, thereby moving the clamping unit 132 to the left until the adhesive paper 111 is delivered between the drive spindle 310 and the battery cell 510. Then, the Z-axis driver 1314 drives the mounting plate 1316 to slide on the Z-axis slide rail 1315, thereby adjusting the position of the clamping unit 132 downwards or upwards, bringing it closer to the battery cell 510. The method of moving the cylinder-driven components is known to those skilled in the art and is feasible, and will not be described in detail in this embodiment.

[0056] To facilitate the use of the adhesive clamping drive unit 131, such as Figure 4 As shown, in some embodiments, the output of the X-axis driver 1311 is connected to the mounting base 1313 via a floating connector, and the output of the Z-axis driver 1314 is connected to the mounting plate 1316 via a floating connector.

[0057] Specifically, the X-axis driver 1311 is connected to the mounting base 1313 via a floating joint, and the Z-axis driver 1314 is connected to the mounting plate 1316 via a floating joint. This floating joint design ensures that the displacement of the clamp-on drive unit 131 can be adjusted, while also preventing installation errors from scratching the cylinder inner wall and causing leaks. It also helps reduce errors, protect related components, maintain stable equipment operation, and extend the equipment's service life.

[0058] To facilitate the use of the clamping unit 132, such as Figure 3 and Figure 5 As shown, in some embodiments, the adhesive clamping unit 132 includes an upper clamping plate 1321, a lower clamping plate 1322, and a pneumatic finger 1323. The output end of the pneumatic finger 1323 is connected to the upper clamping plate 1321 and the lower clamping plate 1322 to drive the upper clamping plate 1321 and the lower clamping plate 1322 to move closer or further away from each other. The lower clamping plate 1322 is provided with an air guide port 1324 for flattening the adhesive paper 111.

[0059] Specifically, the pneumatic finger 1323 is mounted on the mounting plate 1316. The upper clamping plate 1321 and the lower clamping plate 1322 are clamped or opened by the pneumatic finger 1323 to clamp or release the adhesive tape 111. It is understood that the left end of the adhesive tape 111 protrudes from the left end of the lower clamping plate 1322, and the adhesive surface of the adhesive tape 111 is located on the lower side to adhere the adhesive tape 111 to the battery cell 510 below. The method by which the pneumatic finger 1323 drives the upper clamping plate 1321 and the lower clamping plate 1322 is known to those skilled in the art and is feasible, and will not be described in detail here. An air vent 1324 is provided on the upper surface of the lower clamping block. When the adhesive tape 111 is clamped, the air vent 1324 can allow air to pass through to flatten the adhesive surface of the adhesive tape 111, preventing the adhesive tape 111 from falling due to gravity and thus affecting the success rate of wrapping.

[0060] It is worth noting that the number and shape of the air guide ports 1324 are subject to actual production needs and are not limited here. For example, the width of the end of the air guide port 1324 near the upper clamping plate 1321 is greater than the width of the end away from the upper clamping plate 1321. In this way, the cross-sectional area of ​​the upper end of the air guide port 1324 is larger, which makes the airflow diffusion direction wider, thereby making the effect of the blown adhesive paper 111 better.

[0061] To facilitate timely cutting of the adhesive tape 111, such as Figure 3 As shown, in some embodiments, the glue feeding mechanism 100 further includes a glue cutting assembly 140, which includes a glue cutting driver 141 and a cutter 142, with the output end of the glue cutting driver 141 connected to the cutter 142.

[0062] Specifically, the glue-cutting actuator 141 is mounted on the frame 400 and positioned between the Y-axis actuator and the drive spindle 310. The glue-cutting actuator 141 drives the cutter 142 to cut the adhesive paper 111. After the adhesive is applied, the pneumatic finger 1323 again controls the upper clamping plate 1321 and the lower clamping plate 1322 to clamp the adhesive paper 111, and then the glue-cutting actuator 141 drives the cutter 142 to cut the adhesive paper 111. The glue-cutting actuator 141 can be, but is not limited to, a three-axis cylinder 2231. The method by which the three-axis cylinder 2231 drives the cutter 142 to cut the adhesive paper 111 is known to those skilled in the art and is feasible; therefore, it will not be described in detail in this embodiment.

[0063] To facilitate the clamping of adhesive by the clamping unit 132, such as Figure 3 As shown, in some embodiments, the lower clamping plate 1322 protrudes from the end of the upper clamping plate 1321 near the drive spindle 310.

[0064] Specifically, the left end of the lower clamping plate 1322 protrudes beyond the left end of the upper clamping plate 1321. This allows the left end of the lower clamping plate 1322 to support the adhesive tape 111 when the cutter 142 cuts it, making it easier for the cutter 142 to cut the tape. It also facilitates the guiding and conveying of the adhesive tape 111.

[0065] Working principle:

[0066] like Figures 1 to 4 As shown, after the battery cell 510 is transported to the designated position by the glue feeding mechanism 100, two three-axis cylinders 2231 respectively push the front abutment 2232 and the rear abutment 2233 to clamp the battery cell 510; the lifting driver 211 pushes the positioning frame 221 upward, thereby raising the positioning assembly 220 and sending the battery cell 510 to the glue wrapping position; the adhesive paper 111 is transported to the designated position by the unwinding reel 110 through each glue output roller 120; the pneumatic finger 1323 controls the upper clamping plate 1321 and the lower clamping plate 1322 to clamp the adhesive paper 111; then the X-axis driver 1311 starts to work, pushing the mounting base 1313 to move to the left along the X-axis slide rail 1312 through the floating joint, sending the adhesive paper 111 between the drive spindle 310 and the battery cell 510. During this period, the Z-axis driver 1314 can push the mounting plate 1316 through the floating joint to make the glue clamping unit 132 move along the Z-axis slide rail 131. The device moves in five directions to adjust its position; simultaneously, the adhesive wrapping driver 320 starts working, driving the drive spindle 310 to rotate, which in turn drives the battery cell 510 to rotate, starting to wrap the adhesive tape 111 onto the battery cell 510; during the adhesive wrapping process, the pneumatic finger 1323 controls the upper clamping plate 1321 and the lower clamping plate 1322 to release the adhesive tape 111, and the X-axis driver 1311 drives the adhesive clamping unit 132 to move to the right; after the adhesive wrapping is completed, the pneumatic finger 1323 again controls the upper clamping plate 1321 and the lower clamping plate 1322 to clamp the adhesive tape 111, and then the adhesive cutting driver 141 drives the cutter 142 to cut the adhesive tape 111, and then resets, while the adhesive wrapping driver 320 continues to work, completely wrapping the adhesive tape 111 onto the battery cell 510; the lifting driver 211 drives the positioning assembly 220 to descend; the three-axis cylinder 2231 drives the front abutment 2232 and the rear abutment 2233 to reset. As can be seen, the equipment has a compact structure, enabling continuous and uninterrupted adhesive application with high efficiency; the adhesive tape 111 does not wrinkle, resulting in good adhesive application and thus achieving the desired effect. Figure 6 The 510 battery cell with the tape applied is 111.

[0067] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0068] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0069] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0070] In this invention, unless otherwise expressly specified and limited, "above or below" the first feature may include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on" the first feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the first feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0071] Although the description of this utility model has been given in conjunction with the specific embodiments described above, it is obvious to those skilled in the art that many substitutions, modifications, and variations can be made based on the above description. Therefore, all such substitutions, modifications, and variations are included within the spirit and scope of the appended claims.
