Description

Technical Field

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

[0002] With the rapid development of the battery industry, cell assembly processes are becoming increasingly sophisticated, standardized, and reliable in their design. Among these processes, the winding of the cell tape is an essential step in cell assembly, and the industry is placing increasingly higher demands on it.

[0003] Battery cell tape primarily serves for insulation and fixation, protecting the battery's internal structure and preventing safety hazards after assembly. However, some battery cell tape wrapping positions have specific requirements, such as needing to be wrapped around the end of the cell so that the tape extends beyond the cell's end. Currently, this type of wrapping is usually done manually, which is inefficient, results in poor tape consistency, and leads to a low yield rate. Utility Model Content

The elastic member is connected to the second positioning member and the second support member respectively. When the cylindrical cell is in the coating space, the cylindrical cell squeezes the second positioning member in the direction away from the first positioning member.

[0039] Please see Figures 1 to 4 One embodiment of this utility model provides an automatic coating device for cylindrical battery cells, including: a battery cell conveying mechanism 10, a battery cell lifting mechanism 20, a coating dispensing mechanism 30, and a tape transfer mechanism 40;

[0040] The cell conveying mechanism 10 is used to convey cylindrical cells 50;

[0041] The cell lifting mechanism 20 is used to drive the cylindrical cell 50 to rise, fall and rotate. The cell lifting mechanism 20 is located on the side of the cell conveying mechanism 10. The cell lifting mechanism 20 includes a first support component 21, a second support component 22, a rotary pressing component 23 and a two-axis translation drive component 24.

[0042] The first support component 21 includes a first support member 211 and a first positioning member 212, wherein the first positioning member 212 is disposed on the first support member 211;

[0043] The second support assembly 22 includes a second support member 221, an elastic member (not shown), and a second positioning member 222. The second support member 221 and the first support member 211 are respectively disposed on both sides of the cell conveying mechanism 10. The second positioning member 222 is movably disposed on the second support member 221 and can move in the direction of approaching and moving away from the first positioning member 212. The first positioning member 212 and the second positioning member 222 are respectively positioned and engaged with the end of the cylindrical cell 50. A coating space 25 for restricting the cylindrical cell 50 is formed between the first support member 211, the second support member 221, the first positioning member 212, and the second positioning member 222. The elastic member is connected to the second positioning member 222 and the second support member 221 respectively. When the cylindrical cell 50 is in the coating space 25, the cylindrical cell 50 squeezes the second positioning member 222 in the direction away from the first positioning member 212. The elastic member generates elastic deformation, and the elastic force of the elastic member drives the second positioning member 222 to press the cylindrical cell 50 towards the first positioning member 212.

[0044] The rotary clamping assembly 23 is disposed on the side or top of the overmolding space 25 and is used to drive the cylindrical battery cell 50 to rotate.

[0045] The two-axis translation drive assembly 24 is driven to connect with the first support member 211 and the second support member 221. The first support member 211 and the second support member 221 move closer to each other and further away from each other under the drive of the two-axis translation drive assembly 24, and move up and down under the drive of the two-axis translation drive assembly 24.

[0046] The adhesive dispensing mechanism 30 is used to dispense the adhesive tape 60;

[0047] The tape transfer mechanism 40 is located between the glue dispensing mechanism 30 and the cell lifting mechanism 20. The tape transfer mechanism 40 drives the tape 60 to move from the glue dispensing mechanism 30 to the glue wrapping space 25.

[0048] In this embodiment, the example is taken where, after the coating is completed, the front half 61 of the tape 60 is suspended while the rear half 62 of the tape 60 is attached to the outer peripheral surface of the cylindrical cell 50. The purpose of this coating method is that the front half 61 of the tape 60 can be attached to the end of the cylindrical cell 50 in a subsequent step, so that the tape 60 can seal the end edge of the cylindrical cell 50.

[0049] The working principle of an automatic coating device for cylindrical battery cells according to one embodiment of the present invention is described below:

[0050] Cell positioning steps: The cell conveying mechanism 10 conveys the cylindrical cell 50 between the first support member 211 and the second support member 221. The two-axis translation drive assembly 24 drives the first support member 211 and the second support member 221 to move closer to each other until the first support member 211 and the second support member 221 are at the bottom of the cylindrical cell 50 and the first positioning member 212 and the second positioning member 222 respectively abut against the two ends of the cylindrical cell 50, and the rotation pressing assembly 23 abuts against the outer circumferential surface of the cylindrical cell 50. Then the two-axis translation drive assembly 24 drives the first support member 211 and the second support member 221 to rise so that the cylindrical cell 50 is removed from the cell conveying mechanism 10. When the first positioning member 212 and the second positioning member 222 abut against the two ends of the cylindrical battery cell 50, the second positioning member 222 will be unable to move after contacting the cylindrical battery cell 50. The second positioning member 222 will stretch or compress the elastic member, causing the elastic member to undergo elastic deformation. The elastic deformation of the elastic member can be used to adapt to cylindrical battery cells 50 of different lengths. The elastic force of the elastic member can also provide buffering to prevent the second positioning member 222 from impacting the cylindrical battery cell 50.

[0051] Steps for taking tape 60: The tape 60 is released by the tape dispensing mechanism 30, and the tape transfer mechanism 40 moves the tape 60 to the tape wrapping space 25.

[0052] The battery cell positioning step and the tape removal step 60 can be performed simultaneously to improve work efficiency. Of course, they can also be performed at different times.

[0053] Coating Step: After the tape 60 is moved to the coating space 25, the tape 60 is placed at the edge of the outer peripheral surface of the cylindrical cell 50. At this time, a portion of the rear half 62 of the tape 60 is initially bonded to the outer peripheral surface of the cylindrical cell 50, while the front half 61 of the tape 60 extends from the end of the cylindrical cell 50 along the axial direction of the cylindrical cell 50. Next, the rotary clamping assembly 23 rotates, and the cylindrical battery cell 50 is driven to rotate by the friction between the rotary clamping assembly 23 and the cylindrical battery cell 50. As the cylindrical battery cell 50 rotates, the rear half 62 of the tape 60 moves between the rotary clamping assembly 23 and the outer circumferential surface of the cylindrical battery cell 50. The rear half 62 of the tape 60 will be pressed on the outer circumferential surface of the cylindrical battery cell 50, realizing the tape 60 wrapping the cylindrical battery cell 50. After the wrapping is completed, the rear half 62 of the tape 60 is adhered to the outer circumferential surface of the cylindrical battery cell 50 around the circumference of the cylindrical battery cell 50, while the front half 61 of the tape 60 extends from the end of the cylindrical battery cell 50. Finally, the two-axis translation drive assembly 24 drives the first support member 211 and the second support member 221 to descend, causing the cylindrical battery cell 50 to fall back onto the battery cell conveying mechanism 10. The two-axis translation drive assembly 24 drives the first support member 211 and the second support member 221 to move away from each other, thereby separating the first support member 211 and the second support member 221 from the cylindrical battery cell 50. The battery cell conveying mechanism 10 can then convey the coated cylindrical battery cell 50 away and convey the next cylindrical battery cell 50 into the space between the first support member 211 and the second support member 221 for coating.

[0054] The specific structure of the elastic element can be designed according to actual needs. For example, the elastic element can be a sheet or a spring. In this embodiment, the elastic element is a spring. The two ends of the spring are connected to the second positioning element 222 and the second support element 221, respectively. The second positioning element 222 is slidably engaged with the second support element 221 through two guide rods 2221, and the spring can be sleeved on the outside of the guide rods 2221.

[0055] Please see Figure 5 and Figure 6 In some optional embodiments, both the first support member 211 and the second support member 221 include a support base 2111 and two support portions 2112. The two support portions 2112 are arranged side by side on the support base 2111 and located at the bottom of the coating space 25. The support portions 2112 are rotatably engaged with the support base 2111, and the two-axis translation drive assembly 24 is drivenly connected to the support base 2111. Since the cylindrical battery cell 50 is coated in a horizontal position, the bottom surface of the cylindrical battery cell 50 is part of the outer peripheral surface and is curved. The two support portions 2112 support the bottom surface of the cylindrical battery cell 50 on both sides, making the cylindrical battery cell 50 more stable when rotating circumferentially.

[0056] In some optional embodiments, the rotary clamping assembly 23 includes a clamping roller 231 and a rotary drive module 232. The clamping roller 231 is rotatably disposed on the side or top of the overmolding space 25. The rotary drive module 232 is driven to the clamping roller 231. The clamping roller 231 presses against the outer peripheral surface of the cylindrical battery cell 50. The rotary drive module 232 drives the clamping roller 231 to rotate, thereby driving the cylindrical battery cell 50 to rotate through the clamping roller 231. The rotary drive module 232 may be a rotary drive motor. The output shaft of the rotary drive motor is driven to the clamping roller 231. In this embodiment, the rotary drive motor is disposed on the second positioning member 222 and can move together with the second positioning member 222.

[0057] In some optional embodiments, the second positioning member 222 is provided with a positioning part 2222 that abuts against the cylindrical battery cell 50. The diameter of the positioning part 2222 is smaller than the diameter of the cylindrical battery cell 50, so that when the positioning part 2222 abuts against the cylindrical battery cell 50, the positioning part 2222 is within the projection range of the cylindrical battery cell 50 in the projection direction parallel to the axial direction of the cylindrical battery cell 50. This helps to avoid the positioning part 2222 from contacting the front half 61 of the tape 60. The positioning part 2222 can avoid the tape 60, thereby facilitating the implementation of a special coating method.

[0058] In some optional embodiments, the positioning part 2222 is provided with a positioning groove 2223, which is positioned and engaged with the electrode 51 of the cylindrical cell 50, thereby improving the positioning stability of the cylindrical cell 50.

[0059] The specific structure of the two-axis translation drive assembly 24 can be selected according to actual needs. For example, in some optional embodiments, the two-axis translation drive assembly 24 includes two lifting drive modules 241 and two lateral translation drive modules 242. The two lifting drive modules 241 are respectively arranged on both sides of the cell conveying mechanism 10 and are driven connected to the first support member 211 and the second support member 221. The two lateral translation drive modules 242 are respectively arranged on both sides of the cell conveying mechanism 10 and are driven connected to the first support member 211 and the second support member 221. The rotation pressing assembly 23 is arranged on the first positioning member 212 or the second positioning member 222. In this embodiment, the lifting drive module 241 is driven to connect with the lateral translation drive module 242, and the lateral translation drive module 242 is directly driven to connect with the first support member 211 or the second support member 221. The lifting drive module 241 drives the lateral translation drive module 242 to lift, thereby indirectly driving the first support member 211 or the second support member 221 to lift. Of course, in other embodiments, the lateral translation drive module 242 can also be driven to connect with the lifting drive module 241, and the lifting drive module 241 can be directly driven to connect with the first support member 211 or the second support member 221. The lateral translation drive module 242 drives the lifting drive module 241 to translate, thereby indirectly driving the first support member 211 or the second support member 221 to move.

[0060] Of course, the two-axis translation drive assembly 24 can also be driven and connected to the rotary pressing assembly 23 independently. That is, the two-axis translation drive assembly 24 also includes a third lateral translation drive module 242 and a third lifting drive module 241. When the first support member 211, the second support member 221, the first positioning member 212 and the second positioning member 222 are in place, the third lifting drive module 241 and the third lateral translation drive module 242 drive the rotary pressing assembly 23 to move to the side or top of the rubber-coating space 25.

[0061] The specific structures of the lifting drive module 241 and the lateral translation drive module 242 can be designed according to actual needs. For example, the lifting drive module 241 and the lateral translation drive module 242 can be a lead screw drive module, a rotary motor translation drive module, a belt translation drive module, a cylinder translation drive module, or a linear motor translation drive module, etc. In this embodiment, the lifting drive module 241 adopts a linear motor translation drive module, and the lateral translation drive module 242 adopts a rotary motor translation drive module.

[0062] Please see Figure 7The specific structure of the glue dispensing mechanism 30 can be selected according to actual needs. For example, in some optional embodiments, the glue dispensing mechanism 30 includes a glue storage component 31, a first clamping component 32, a cutting component 33, a second clamping component 34, and a clamping translation component 35. The glue storage component 31 is used to store the tape 60. The first clamping component 32 and the second clamping component 34 are both used to clamp the tape 60. The cutting component 33 is disposed between the first clamping component 32 and the second clamping component 34. The clamping translation component 35 is driven to connect with the second clamping component 34. The second clamping component 34 moves closer to and further away from the first clamping component 32 under the drive of the clamping translation component 35. The tape 60 released by the glue storage component 31 passes sequentially through the first clamping component 32 and the cutting component 33, and then reaches the second clamping component 34. The tape transfer mechanism 40 drives the tape 60 to move from the cutting component 33 and the second clamping component 34 to the coating space 25. The tape 60 taking steps: The end of the tape 60 wound on the adhesive storage component 31 passes sequentially through the first clamping component 32 and the cutting component 33, and is clamped by the second clamping component 34. The second clamping component 34 clamps the end of the tape 60 and moves away from the first clamping component 32 until the tape 60 is pulled to a suitable length. Then, the first clamping component 32 clamps the tape 60 tightly, and the cutting component 33 cuts the tape 60. Subsequently, the tape transfer mechanism 40 moves the cut tape 60 to the wrapping space 25, and the second clamping component 34 moves towards the first clamping component 32 and clamps the end of the cut tape 60. Then, the second clamping component 34 moves away from the first clamping component 32, so that the tape 60 is pulled to a suitable length again, and the next segment of tape 60 is cut.

[0063] The specific structure of the glue storage assembly 31 can be selected according to actual needs. For example, the glue storage assembly 31 can use a winding wheel, which can wind up the tape 60.

[0064] The specific structures of the first clamping assembly 32 and the second clamping assembly 34 can be selected according to actual needs. For example, the first clamping assembly 32 and the second clamping assembly 34 can be finger cylinders. In this embodiment, the first clamping assembly 32 and the second clamping assembly 34 include two clamping plates and a power module for driving the two clamping plates to clamp and cooperate. The power module can be a cylinder or an electric cylinder, etc. The two clamping plates can cooperate to clamp the adhesive tape 60. The clamping translation assembly 35 is driven and connected to the power module of the second clamping assembly 34.

[0065] The specific structure of the clamping and translation component 35 can be selected according to actual needs. For example, the clamping and translation component 35 can be a lead screw drive component, a rotary motor translation drive component, a belt translation drive component, a cylinder translation drive component, or a linear motor translation drive component, etc. In this embodiment, the clamping and translation component 35 adopts a linear motor translation drive component.

[0066] The specific structure of the cutting assembly 33 can be selected according to actual needs. For example, the cutting assembly 33 includes a cutting blade and a cutting moving module. The cutting moving module drives the cutting blade to move towards the tape 60 to cut the tape 60. The cutting moving module can be a lead screw drive module, a rotary motor translation drive module, a belt translation drive module, a cylinder translation drive module, or a linear motor translation drive module, etc. When the cutting blade is cutting, the first clamping assembly 32 and the second clamping assembly 34 clamp the tape 60 to straighten the tape 60, thereby preventing the tape 60 from bending during cutting and causing cutting failure.

[0067] In some optional embodiments, the adhesive dispensing mechanism 30 further includes a plurality of guide rollers 36 disposed between the adhesive storage assembly 31 and the first clamping assembly 32. The adhesive tape 60 dispensed from the adhesive storage assembly 31 sequentially passes through the plurality of guide rollers 36, the first clamping assembly 32, and the cutting assembly 33, and then reaches the second clamping assembly 34. The guide rollers 36 are used to tighten the adhesive tape 60, preventing the adhesive tape 60 from bending and adhering to other structures. In this embodiment, the guide rollers 36 and the take-up reel are rotatably mounted on a frame located on one side of the cell conveying mechanism 10.

[0068] The specific structure of the tape transfer mechanism 40 can be selected according to actual needs. The tape transfer mechanism 40 can adsorb the tape 60 in different ways. For example, in some optional embodiments, the tape transfer mechanism 40 includes a vacuum adsorption component 41 and a moving drive component 42. The vacuum adsorption component 41 is used to adsorb the tape 60, and the moving drive component 42 is driven by the vacuum adsorption component 41. Under the drive of the moving drive component 42, the vacuum adsorption component 41 moves from the adhesive dispensing mechanism 30 to the adhesive wrapping space 25. The vacuum adsorption component 41 is connected to a vacuum generating device and has several vacuum adsorption holes. A negative pressure is formed at the vacuum adsorption holes, thereby achieving the adsorption of the tape 60. Of course, the tape transfer mechanism 40...

[0069] The specific structure of the moving drive assembly 42 can be selected according to actual needs. For example, the moving drive assembly 42 can drive the vacuum adsorption assembly 41 to translate. The moving drive assembly 42 can be a lead screw drive assembly, a rotary motor translation drive assembly, a belt translation drive assembly, a cylinder translation drive assembly, or a linear motor translation drive assembly, etc. Alternatively, the moving drive assembly 42 can drive the vacuum adsorption assembly 41 to move by rotating it. For example, the moving drive assembly 42 includes a swing arm and a swing drive module. The swing drive module drives the swing arm to rotate, and the vacuum adsorption assembly 41 is mounted on the swing arm. The swing drive module can be a telescopic assembly or a motor. Of course, if the path between the glue-coating space 25 and the glue-dispensing mechanism 30 is relatively complex, the moving drive assembly 42 can also be a multi-axis translation drive assembly. The multi-axis translation drive assembly drives the vacuum adsorption assembly 41 to translate in at least two directions, or translate in at least one direction and rotate in another direction. The structure of the multi-axis translation drive assembly is a technology known to those skilled in the art and will not be described in detail here.

[0070] In some optional embodiments, the cell conveying mechanism 10 includes a conveying assembly 11 and a plurality of cell positioning seats 12. The plurality of cell positioning seats 12 are arranged equidistantly along the conveying direction of the conveying assembly 11. The cell positioning seats 12 are provided with positioning grooves 121 that cooperate with the positioning of the cylindrical cell 50. The second support member 221 and the first support member 211 are respectively provided on both sides of the conveying assembly 11, and the cell positioning seat 12 is located between the first support member 211 and the second support member 221. The positioning groove 121 is used to position the cylindrical cell 50. The cylindrical cell is placed horizontally in the positioning groove 121, and both ends of the cylindrical cell 50 extend from both sides of the positioning groove 121 to outside the positioning groove 121. The first support member 211 and the second support member 221 are movable to both sides of the positioning seat and support the bottom of the part of the cylindrical cell 50 that extends out of the positioning groove 121.

[0071] The conveying assembly 11 can be a mesh belt conveying assembly, a roller conveying assembly, a chain conveying assembly, or a belt conveying assembly, etc. For example, in this embodiment, the conveying assembly 11 can be a belt conveying assembly, and multiple battery cell positioning seats 12 are arranged sequentially along the conveying direction of the belt of the belt conveying assembly.

[0072] In some optional embodiments, the automatic coating equipment for cylindrical battery cells also includes a controller. The controller is signal-connected to the battery cell conveying mechanism 10, the battery cell lifting mechanism 20, the glue dispensing mechanism 30, and the tape transfer mechanism 40, and is used to control the operation of the battery cell conveying mechanism 10, the battery cell lifting mechanism 20, the glue dispensing mechanism 30, and the tape 60 transfer mechanism 40. The controller can be signal-connected wirelessly or wiredly to structures such as the conveying assembly 11, the rotary drive module 232, the lifting drive module 241, the lateral translation drive module 242, the first clamping assembly 32, the cutting assembly 33, the second clamping assembly 34, the clamping translation assembly 35, the tape 60 transfer mechanism 40, the vacuum adsorption assembly 41, and the movement drive assembly 42, thereby facilitating automated control.

[0073] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
