Description

Technical Field

[0001] This application relates to the technical field of lithium battery coating, and more particularly to a coating device. Background Technology

[0002] With the country's vigorous promotion of new energy development, the demand for lithium batteries is increasing across all industries, with the electric vehicle industry being particularly prominent. In the later stages of lithium battery manufacturing, a blue film needs to be coated on the outside of the battery. The main function of this blue film is to protect the battery from external scratches or electrolyte corrosion.

[0003] In the existing technology, the process of coating the outside of lithium batteries with blue film is mostly still in a semi-automatic processing mode, which still requires human intervention to assist in the processing. Not only is the equipment structure complex, but the coating efficiency is also low, making it difficult to guarantee the coating quality and adapt to the needs of mass production and high-efficiency processing.

The process involves placing a rolled strip of film onto a film supply device, which then outputs the film to the entrance of the coating area. A feeding robot pushes the film from the entrance into the coating area. As the film passes through the coating area, a pressing mechanism presses the film onto the upper and lower surfaces of the material. A cutting mechanism then cuts off the portion of the film pressed onto the material to form a sheet film covering both surfaces. Finally, a picking robot picks up the film from the feeding robot and removes it from the coating area. This simple structure achieves automated coating without human intervention, significantly improving coating efficiency and avoiding the impact of human error on coating quality. This ensures better coating quality and better meets the demands of mass production and high-efficiency processing. Attached Figure Description

[0073] The present application will be further described below with reference to the accompanying drawings and preferred embodiments, but the implementation of the present application is not limited thereto.

[0074] Please see Figures 1 to 7 The coating equipment 100 of this application is suitable for cutting and attaching a rolled strip film 200 to cover the material 202. For ease of description, in this embodiment, the coating equipment 100 of this application coats nine areas on the sheet film 201 ( Figure 1 The sheet-like film 201 shown includes regions A1, A2, A3, A4, A5, A6, A7, A8, and A9, which are pressed onto the five surfaces of the material 202. Figure 2In the material 202 shown: the upper surface S1, the left surface S2, the lower surface S3, the front surface S4, and the rear surface S5. Specifically, region A1 of the sheet film 201 is attached to surface S1 of the material 202, region A2 of the sheet film 201 is attached to surface S2 of the material 202, region A3 of the sheet film 201 is attached to surface S3 of the material 202, regions A4, A5, and A6 of the sheet film 201 are attached to surface S4 of the material 202, and regions A7, A8, and A9 of the sheet film 201 are attached to surface S5 of the material 202.

[0075] The coating equipment 100 of this application includes: a frame 10 and a film supply device 20, a cutting mechanism 30, a pressing mechanism 40, a feeding robot 80a, and a picking robot 80b, all mounted on the frame 10. A coating area 11 is distributed on the frame 10. The film supply device 20 carries a roll of strip film 200 and outputs it to the entrance of the coating area 11. The feeding robot 80a pushes the material 202 against the strip film 200 located at the entrance of the coating area 11. Upon entering the coating area 11, the pressing mechanism 40 presses the strip film 200 located within the coating area 11 onto the upper and lower surfaces of the material 202 passing through the coating area 11. The cutting mechanism 30 cuts out the portion of the strip film 200 pressed onto the upper and lower surfaces of the material 202 to form a sheet film 201 covering the upper and lower surfaces of the material 202. The picking robot 80b receives the material 202 covered with the sheet film 201 from the feeding robot 80a and removes it from the coating area 11. The specific structure and working principle of the feeding robot 80a and the picking robot 80b are well known to those skilled in the art and are conventional technical means, therefore, they will not be described in detail here. The rolled strip film 200 is placed on the film supply device 20, and then the film supply device 20 outputs the strip film 200 to the entrance of the coating area 11. Then, the feeding robot 80a pushes the material 202 at the entrance of the coating area 11 and moves the strip film 200 into the coating area 11. During the process of the material 202 passing through the coating area 11, the pressing mechanism 40 presses the strip film 200 in the coating area 11 onto the upper and lower surfaces of the material 202. Then, the cutting mechanism 30 cuts out the part of the strip film 200 pressed onto the upper and lower surfaces of the material 202 to form a sheet film 201 covering the upper and lower surfaces of the material 202. Then, the picking robot 80b picks up the material 202 covered with the sheet film 201 from the feeding robot 80a and moves it out of the coating area 11. With a simple structure, it achieves automated coating without human intervention, significantly improving coating efficiency and avoiding the impact of human instability on coating quality. This ensures better coating quality and better adapts to the demands of mass production and high-efficiency processing. Specifically, as follows:

[0076] Please continue reading. Figures 1 to 7The pressing mechanism 40 includes: a first lifting drive mechanism 41, a second lifting drive mechanism 42, a first lifting frame 43, a second lifting frame 44, a first pressing roller 45, and a second pressing roller 46. The first lifting drive mechanism 41 and the second lifting drive mechanism 42 are both vertically mounted on the frame 10. The first lifting frame 43 and the second lifting frame 44 move vertically on the frame 10. The first lifting frame 43 is driveably connected to the first lifting drive mechanism 41, and the second lifting frame 44 is driveably connected to the second lifting drive mechanism 42. The first lifting frame 43 can be driven vertically up and down by the first lifting drive mechanism 41, and the second lifting frame 44 can be driven vertically up and down by the second lifting drive mechanism 42. The first pressing roller 45 is pivotally connected to the first lifting frame 43 in the front-to-back direction, and the second pressing roller 46 is pivotally connected to the second lifting frame 44 in the front-to-back direction. The first pressing roller 45 is located above the second pressing roller 46, and the coating area 11 is located vertically between the first pressing roller 45 and the second pressing roller 46. Furthermore, the pressing mechanism 40 also includes: a third lifting drive mechanism 47a, a fourth lifting drive mechanism 48a, a third lifting frame 47b, a fourth lifting frame 48b, a first pressing scraper 49a, and a second pressing scraper 49b. The third lifting drive mechanism 47a and the fourth lifting drive mechanism 48a are both vertically mounted on the frame 10. The third lifting frame 47b and the fourth lifting frame 48b are both vertically movable on the frame 10. The third lifting frame 47b is driven by the third lifting drive mechanism 47a, and the fourth lifting frame 48b is driven by the fourth lifting drive mechanism 48a. Thus, the third lifting frame 47b can be driven vertically up and down by the third lifting drive mechanism 47a, and the fourth lifting frame 48b can be driven vertically up and down by the fourth lifting drive mechanism 48a. The first pressing scraper 49a is fixed to the third lifting frame 47b in the front-back direction, and the second pressing scraper 49b is fixed to the fourth lifting frame 48b in the front-back direction. The first pressing scraper 49a is located above the second pressing scraper 49b and is located to the left of the first pressing roller 45. The second pressing scraper 49b is located to the left of the second pressing roller 46. Then, when the feeding robot 80a moves the material 202 into the coating area 11, firstly, the area A2 of the sheet film 201 is attached to the surface S2 of the material 202. Then, the first lifting drive mechanism 41 drives the first lifting frame 43 to move the first pressure roller 45 vertically downward. At the same time, the second lifting drive mechanism 42 drives the second lifting frame 44 to move the second pressure roller 46 vertically upward, so that the first pressure roller 45 rolls the area A1 of the sheet film 201 to be attached to the surface S1 of the material 202, and the second pressure roller 46 rolls the area A3 of the sheet film 201 to be attached to the surface S3 of the material 202.When the material 202 is moved below the first pressing scraper 49a, the third lifting drive mechanism 47a drives the third lifting frame 47b to move the first pressing scraper 49a vertically downward. At the same time, the fourth lifting drive mechanism 48a drives the fourth lifting frame 48b to move the second pressing scraper 49b vertically upward. This causes the area A1 of the sheet film 201 scraped by the first pressing scraper 49a to adhere to the surface S1 of the material 202, and the area A3 of the sheet film 201 scraped by the second pressing scraper 49b to adhere to the surface S3 of the material 202. As a result, the area A1 of the sheet film 201 is completely adhered to the surface S1 of the material 202, and the area A3 of the sheet film 201 is completely adhered to the surface S3 of the material 202. In this embodiment, there may be a problem that the first pressing roller 45 cannot completely press the right edge of the surface S1 of the material 202, and the second pressing roller 46 cannot completely press the right edge of the surface S3 of the material 202. However, the first pressing scraper 49a can completely press the right edge of the surface S1 of the material 202, and the second pressing scraper 49b can completely press the right edge of the surface S3 of the material 202. Thus, through the secondary pressing action of the first pressing scraper 49a and the second pressing scraper 49b, it is ensured that the area A1 of the sheet film 201 is completely attached to the surface S1 of the material 202, and the area A3 of the sheet film 201 is completely attached to the surface S3 of the material 202, resulting in a more reasonable structure.

[0077] It should be noted that the specific structure and working principle of the first lifting drive mechanism 41, the second lifting drive mechanism 42, the third lifting drive mechanism 47a and the fourth lifting drive mechanism 48a are well known to those skilled in the art. For example, a drive structure that uses a motor to drive the lead screw to rotate and drive the lead screw nut to move, or a cylinder drive, are all conventional technical means. Therefore, they will not be described in detail here.

[0078] Please continue reading. Figures 1 to 7The film supply device 20 includes: an unwinding mechanism 21, a film preparation mechanism 22, and a film pulling mechanism 23, all mounted on the frame 10. The unwinding mechanism 21 carries a rolled strip of film 200. The film preparation mechanism 22 pulls the strip of film 200 out of the unwinding mechanism 21. The film pulling mechanism 23 pulls the strip of film 200 from the film preparation mechanism 22 to the wrapping area 11. Specifically, the film preparation mechanism 22 includes: a first guide roller 221, a second guide roller 222, a third guide roller 223, a first linear actuator 224, a second linear actuator 225, a fifth lifting frame 226, and a lifting pressure plate 227. The first guide roller 221 and the second guide roller 222 are both pivotally connected to the frame 10 in the front-rear direction. The first guide roller 221 is located to the right of the second guide roller 222. The first linear actuator 224 can be a cylinder, but is not limited thereto.

The fifth lifting frame 226 moves vertically on the frame 10 and is fixedly connected to the drive end of the first linear actuator 224.

The unwinding mechanism 21 is located to the right of the first guide roller 221. After the strip film 200 is output from the unwinding mechanism 21 and the release paper 203 is torn off, it is first wound around the top side of the first guide roller 221, then around the bottom side of the third guide roller 223, and then around the top side of the second guide roller 222. When film preparation is required, the second linear actuator 225 drives the lifting pressure plate 227 to press the strip film 200 against the top side of the second guide roller 222 to prevent the strip film 200 from being transported in reverse. Then, the first linear actuator 224 drives the fifth lifting frame 226 to move the third guide roller 223 downward. The third guide roller 223 presses the strip film 200 downward, thereby pulling the strip film 200 out of the unwinding mechanism 21, completing the film preparation operation of the strip film 200 for use in subsequent processes.

[0079] Furthermore, the film-pulling mechanism 23 includes: a fifth lifting drive mechanism 231, a sixth lifting frame 232, a third linear actuator 233, a first translation frame 234, a film-pulling rod 235, a brake mechanism 236, and a first auxiliary pressure roller 237. The fifth lifting drive mechanism 231 is mounted on the frame 10, and the sixth lifting frame 232 moves vertically on the frame 10. The sixth lifting frame 232 is connected to the fifth lifting drive mechanism 231, allowing the fifth lifting drive mechanism 231 to drive the sixth lifting frame 232 to move vertically up and down. It should be noted that the specific structure and working principle of the fifth lifting drive mechanism 231 are well known to those skilled in the art. For example, a drive structure that uses a motor to drive the lead screw to rotate and drive the lead screw nut to move horizontally, or a cylinder drive, can be used. These are all conventional technical means, and therefore will not be described in detail here. The second guide roller 222 is located above the pressing mechanism 40, and the sixth lifting frame 232 moves below the second guide roller 222. The third linear actuator 233 can be selected as a cylinder, but is not limited thereto. The third linear actuator 233 is fixed to the sixth lifting frame 232 in the left-right direction. The first translation frame 234 is movable on the sixth lifting frame 232 in the left-right direction and is fixedly connected to the output end of the third linear actuator 233. The film-pulling rod 235 is pivotally connected to the first translation frame 234 in the front-back direction. The brake mechanism 236 is located on the first translation frame 234, and the end of the film-pulling rod 235 is associated with the brake mechanism 236. The brake mechanism 236 can lock to prevent the film-pulling rod 235 from rotating or release to allow the film-pulling rod 235 to rotate. It should be noted that the specific structure and working principle of the brake mechanism 236 are well known to those skilled in the art and are conventional technical means, so they will not be described in detail here. The first auxiliary pressure roller 237 is pivotally connected to the first lifting frame 43 in the front-back direction, and the first auxiliary pressure roller 237 is located directly above the first pressure roller 45. The strip film 200 output by the unwinding mechanism 21 is first wound around the top side of the first pass roller 221, then around the bottom side of the third pass roller 223, then around the top side of the second pass roller 222, then around the right side of the first auxiliary pressure roller 237, and then detachably adhered to the left side of the film pulling rod 235. When the strip film 200 needs to be pulled vertically downward through the wrapping area 11, the fifth lifting drive mechanism 231 drives the sixth lifting frame 232 to move vertically upward until the film pulling rod 235 is directly opposite the first auxiliary pressure roller 237 in the left-right direction and the film pulling rod 235 is located to the right of the first auxiliary pressure roller 237 in the left-right direction. Then, the third linear drive 233 drives the first translation frame 234 to move to the left and approach the first auxiliary pressure roller 237 until the film pulling rod 235 presses against the strip film 200 on the right side of the first auxiliary pressure roller 237. At this time, the brake mechanism 236 locks to prevent the film pulling rod 235 from rotating, so that the strip film 200 is attached to the film pulling rod 235.Then the fifth lifting drive mechanism 231 drives the sixth lifting frame 232 to move vertically downward until the film pulling rod 235 moves downward to a position lower than the second pressure roller 46, thus completing the downward pulling of the strip film 200 through the entrance of the coating area 11.

[0080] Furthermore, the cutting mechanism 30 includes: a cutting translation drive mechanism 31, a second translation frame 32, a fourth linear actuator 33, a first cutter 34, a second auxiliary pressure roller 35, a fifth linear actuator 36, and a horizontal pressing plate 37. The cutting translation drive mechanism 31 is mounted on the frame 10 in the front-back direction, and the second translation frame 32 is mounted on the frame 10 in the front-back direction. The second translation frame 32 is connected to the cutting translation drive mechanism 31, so the cutting translation drive mechanism 31 drives the second translation frame 32 to move in the front-back direction. It should be noted that the specific structure and working principle of the cutting translation drive mechanism 31 are well known to those skilled in the art. For example, a drive structure that uses a motor to drive the lead screw to rotate and drive the lead screw nut to move, or a cylinder drive, etc., can be used. These are all conventional technical means, so they will not be described in detail here. The fourth linear actuator 33 can be a cylinder, but is not limited thereto. The fourth linear actuator 33 is fixed to the second translation frame 32 in the left-right direction. The first cutter 34 is fixedly connected to the drive end of the fourth linear actuator 33, with its blade facing forward. The second auxiliary pressure roller 35 is pivotally connected to the first lifting frame 43 in the front-back direction, and is located directly above the first auxiliary pressure roller 237. The fifth linear actuator 36 can be a cylinder, but is not limited thereto. The fifth linear actuator 36 is fixed to the first lifting frame 43 in the left-right direction. The horizontal pressing plate 37 is fixedly connected to the drive end of the fifth linear actuator 36 in the front-back direction, and is detachably pressed against the right side of the second auxiliary pressure roller 35. The second guide roller 222 is located above the second auxiliary pressure roller 35, and the strip film 200 passes between the second auxiliary pressure roller 35 and the horizontal pressing plate 37. When the film-pulling rod 235 pulls the strip film 200 downwards to a position below the second pressure roller 46, the feeding robot 80a pushes the material 202 into the wrapping area 11, moving the strip film 200 located at the entrance of the wrapping area 11. As the material 202 passes through the wrapping area 11, the pressing mechanism 40 presses the strip film 200 located in the wrapping area 11 onto the upper and lower surfaces of the material 202. Then, the fifth linear actuator 36 drives the horizontal pressing plate 37 to press the strip film 200 against the right side of the second auxiliary pressure roller 35. Then, the fourth linear actuator 33 drives the first cutter 34 to move to the right and extend the strip film 200 between the film pulling rod 235 and the second auxiliary pressure roller 35. Then, the cutting and translation driving mechanism 31 drives the second translation frame 32 to move from front to back, so that the part of the strip film 200 pressed against the upper and lower surfaces of the material 202 can be cut out to form a sheet film 201 covering the upper and lower surfaces of the material 202.

[0081] Please see Figures 1 to 3 and Figure 8The coating equipment 100 of this application further includes a side-cutting mechanism 50 mounted on the frame 10. The side-cutting mechanism 50 is located on the left side of the coating area 11. The material handling robot 80b moves the material 202 covered with sheet film 201 in the coating area 11 to the side-cutting mechanism 50. The side-cutting mechanism 50 includes a side-cutting mounting frame 51, a side-cutting translation frame 52, a sixth linear actuator 53, a seventh linear actuator 54, a side-cutting mounting base 55, a side-cutting baffle 56, a second cutter 57, and a third cutter 58. The side-cutting mounting frame 51 is fixed to the frame 10 and is located on the left side of the coating area 11. The sixth linear actuator 53 can be a cylinder, but is not limited thereto. The sixth linear actuator 53 is fixed to the side-cutting mounting frame 51 in the front-back direction. The side-cutting translation frame 52 moves on the side-cutting mounting frame 51 in the front-back direction and is fixedly connected to the drive end of the sixth linear actuator 53. The side-cutting mounting base 55 moves left and right on the side-cutting translation frame 52. The seventh linear actuator 54 is fixed left and right on the side-cutting mounting base 55, and its drive end is fixedly connected to the side-cutting translation frame 52. The side-cutting baffle 56 is vertically fixed to the side-cutting translation frame 52. The second cutter 57 and the third cutter 58 are horizontally fixed to the side-cutting mounting base 55, spaced apart vertically. The side-cutting baffle 56 is located vertically between the second cutter 57 and the third cutter 58, with the cutting edges of both the second cutter 57 and the third cutter 58 facing left. Thus, the side-cutting baffle 56 blocks the sheet-like film 201 in the vertical direction, and the second cutter 57 and the third cutter 58 cut the sheet-like film 201 on both sides of the side-cutting baffle 56. In this embodiment, side-cutting mechanisms 50 are provided on both the front and rear sides of the left side of the coating area 11, that is, two symmetrical side-cutting mechanisms 50 are provided on the left side of the coating area 11. In other words, in this embodiment, the material 202 that the picking robot 80b moves to the side-cutting mechanism 50 consists of region A1 of the sheet film 201 attached to the surface S1 of the material 202, and region A3 of the sheet film 201 attached to the surface S3 of the material 202. It is necessary to cut the sheet film 201 between regions A4 and A5, between regions A5 and A6, between regions A7 and A8, and between regions A8 and A9. The front-side side-cutting mechanism 50 is driven by the sixth linear actuator 53 to move the side-cutting translation frame 52 and the side-cutting baffle 56 backward to block region A5 of the vertical sheet film 201. Then, the seventh linear actuator 54 drives the side-cutting mounting base 55 to move to the left, so that the second cutter 57 cuts regions A4 and A5 on the sheet film 201 above the side-cutting baffle 56, and drives the third cutter 58 to cut regions A5 and A6 on the sheet film 201 below the side-cutting baffle 56. The cutting between regions A7 and A8, and between regions A8 and A9 on the sheet film 201 is performed by the rear-side side-cutting mechanism 50.

[0082] Please see Figures 1 to 3 and Figure 9 The coating equipment 100 of this application further includes: a side scraping mechanism 60 disposed on the frame 10. The side scraping mechanism 60 includes: a side pressure mounting frame 61, a side pressure clamping and positioning mechanism 62, an eighth linear driver 63, a ninth linear driver 64, a tenth linear driver 65, a side pressure translation frame 66, a first side pressure lifting frame 67a, a second side pressure lifting frame 68a, a first side pressure block 67b, a second side pressure block 68b, a film-removing mounting frame 69a, a pneumatic finger 69b, and a film-removing piece 69c. The side pressure mounting frame 61 is fixed on the frame 10, and the side pressure clamping and positioning mechanism 62 is disposed on the side pressure mounting frame 61. After the material 202 covered with the sheet film 201 is cut into sheet film 201 by the side cutting mechanism 50, it can be clamped and positioned on the side pressure clamping and positioning mechanism 62 to clamp and position the material 202, thereby facilitating the subsequent pressing operation. It should be noted that the specific structure and working principle of the side-pressure clamping and positioning mechanism 62 are well known to those skilled in the art. For example, multiple cylinders can be used to drive multiple clamping blocks to clamp and position the material 202. These are all conventional technical means, so they will not be described in detail here.

[0083] Specifically, the eighth linear actuator 63 is fixed to the side pressure mounting bracket 61 in the front-to-back direction, and the side pressure translation bracket 66 moves on the side pressure mounting bracket 61 in the front-to-back direction. The side pressure translation bracket 66 is fixedly connected to the drive end of the eighth linear actuator 63. The ninth linear actuator 64 is vertically fixed to the side pressure translation bracket 66, and the first side pressure lifting bracket 67a moves vertically on the side pressure translation bracket 66. The first side pressure lifting bracket 67a is fixedly connected to the drive end of the ninth linear actuator 64, and the first side pressure block 67b is fixed to the first side pressure lifting bracket 67a. The tenth linear actuator 65 is vertically fixed to the side pressure translation bracket 66, and the second side pressure lifting bracket 68a moves vertically on the side pressure translation bracket 66. The second side pressure lifting bracket 68a is fixedly connected to the drive end of the tenth linear actuator 65, and the second side pressure block 68b is fixed to the second side pressure lifting bracket 68a. The second side pressure block 68b is located directly below the first side pressure block 67b. The film-dispensing mounting bracket 69a is fixed to the side-pressure mounting bracket 61. The pneumatic finger 69b can be a swing finger cylinder, but is not limited to this. The pneumatic finger 69b is fixed to the film-dispensing mounting bracket 69a, and the film-dispensing plate 69c is fixed to one drive end of the pneumatic finger 69b. Then, after the material 202 is clamped and positioned by the side-pressure clamping and positioning mechanism 62, the pneumatic finger 69b drives the film-dispensing plate 69c to rotate and swing, pushing the vertical sheet film 201 to the left to move away from the horizontal part of the sheet film 201. Then, the eighth linear actuator 63 drives the side pressure translation frame 66 to move in the front-back direction towards the material 202. The ninth linear actuator 64 then drives the first side pressure lifting frame 67a to move the first side pressure block 67b downwards. The tenth linear actuator 65 drives the second side pressure lifting frame 68a to move the second side pressure block 68b upwards, so that the first and second side pressure blocks 67b and 68b respectively scrape and press the sheet-like film 201 downwards to the horizontal position. In this embodiment, the eighth linear actuator 63, the ninth linear actuator 64, the tenth linear actuator 65, the side pressure translation frame 66, the first side pressure lifting frame 67a, the second side pressure lifting frame 68a, the first side pressure block 67b, the second side pressure block 68b, the film-pulling mounting frame 69a, the pneumatic finger 69b, and the film-pulling sheet 69c are provided on both the front and rear sides of the side pressure clamping and positioning mechanism 62. Regions A4 and A6 on the sheet film 201 are scraped and adhered to surface S4 of material 202, and regions A7 and A9 on the sheet film 201 are scraped and adhered to surface S5 of material 202. First, the pneumatic fingers 69b on the front and rear sides drive the corresponding film-pulling plates 69c to rotate and swing, thereby moving regions A5 and A8 on the sheet film 201 to the left, away from regions A4 and A6, and regions A7 and A9, on the sheet film 201.Then, the eighth linear actuator 63 drives the side-pressure translation frame 66 to move in the front-back direction towards the material 202. Next, the ninth linear actuators 64 on both sides drive the first side-pressure lifting frames 67a on both sides to move the corresponding first side-pressure blocks 67b downwards, so that regions A4 and A7 of the sheet film 201 are scraped downwards onto the corresponding surfaces S4 and S5 of the material 202 via the first side-pressure blocks 67b on both sides. Finally, the tenth linear actuator 65 on both sides drives the second side-pressure lifting frames 68a on both sides to move the corresponding second side-pressure blocks 68b upwards, so that regions A6 and A9 of the sheet film 201 are scraped upwards onto the corresponding surfaces S4 and S5 of the material 202 via the second side-pressure blocks 68b on both sides.

[0084] Among them, the eighth linear actuator 63, the ninth linear actuator 64 and the tenth linear actuator 65 can all be selected as cylinders, but are not limited to this.

[0085] Please see Figure 3 In detail, the coating equipment 100 of this application also includes a first transfer device 80c, which transfers the material 202 that has been side-cut on the side-cutting mechanism 50 to the side-scraping mechanism 60. It should be noted that the specific structure and working principle of the first transfer device 80c are well known to those skilled in the art. For example, a transfer robot or other technical solutions can be used, which are all conventional technical means. Therefore, they will not be described in detail here.

[0086] Please see Figures 1 to 3 and Figure 10The coating equipment 100 of this application further includes a side rolling mechanism 70 mounted on the frame 10. The side rolling mechanism 70 includes a roller mounting frame 71, a roller clamping and positioning mechanism 72, an eleventh linear driver 73, a twelfth linear driver 74, a first roller translation frame 75, a second roller translation frame 76, a third roller translation frame 77, an elastic element 78, and a roller cylinder 79. The roller mounting frame 71 is fixed on the frame 10, and the roller clamping and positioning mechanism 72 is mounted on the roller mounting frame 71. After the side scraping mechanism 60 scrapes areas A4 and A6 on the sheet film 201 onto the surface S4 of the material 202, and scrapes areas A7 and A9 on the sheet film 201 onto the surface S5 of the material 202, the material 202 can be clamped and positioned on the roller clamping and positioning mechanism 72 to facilitate subsequent pressing operations. It should be noted that the specific structure and working principle of the measuring roller clamping and positioning mechanism 72 are well known to those skilled in the art. For example, multiple cylinders can be used to drive multiple clamping blocks to clamp and position the material 202. These are all conventional technical means, and therefore will not be described in detail here. Specifically, the eleventh linear actuator 73 is fixed to the measuring roller mounting frame 71 in the left-right direction, and the first measuring roller translation frame 75 moves in the left-right direction on the measuring roller mounting frame 71. The first measuring roller translation frame 75 is fixedly connected to the drive end of the eleventh linear actuator 73. The twelfth linear actuator 74 is fixed to the first measuring roller translation frame 75 in the left-right direction, and the second measuring roller translation frame 76 moves in the left-right direction on the first measuring roller translation frame 75. The second measuring roller translation frame 76 is fixedly connected to the drive end of the twelfth linear actuator 74. The third measuring roller translation frame 77 moves along the front-to-back direction on the second measuring roller translation frame 76. An elastic element 78 abuts against the third measuring roller translation frame 77 and the second measuring roller translation frame 76, and the elastic element 78 constantly drives the third measuring roller translation frame 77 to move towards the measuring roller clamping and positioning mechanism 72. In this embodiment, the elastic element 78 can be selected as a spring. Specifically, the elastic element 78 is compressed and abuts against the third measuring roller translation frame 77 and the second measuring roller translation frame 76, and the elastic force of the elastic element 78 pushes the third measuring roller translation frame 77 towards the measuring roller clamping and positioning mechanism 72. The measuring roller cylinder 79 is pivotally connected to the second measuring roller translation frame 76 in the vertical direction. Then, after the measuring roller clamping and positioning mechanism 72 clamps and positions the material 202, the eleventh linear driver 73 drives the first measuring roller translation frame 75 to move closer to the material 202, and the twelfth linear driver 74 drives the second measuring roller translation frame 76 to move closer to the material 202, so that the measuring roller cylinder 79 rolls on the vertical sheet film 201 part to adhere to the vertical surface of the material 202, and the elastic force of the elastic member 78 pushes the third measuring roller translation frame 77 to move closer to the measuring roller clamping and positioning mechanism 72, so that the measuring roller cylinder 79 maintains rolling on the vertical surface of the material 202.In this embodiment, the front and rear parts of the first measuring roll transfer frame 75 are provided with a twelfth linear actuator 74, a second measuring roll transfer frame 76, a third measuring roll transfer frame 77, an elastic element 78, and a measuring roll cylinder 79, so that the front and rear sides of the material 202 are respectively provided with a twelfth linear actuator 74, a second measuring roll transfer frame 76, a third measuring roll transfer frame 77, an elastic element 78, and a measuring roll cylinder 79, so as to roll and attach the area A5 on the sheet film 201 to the surface S4 of the material 202, and roll and attach the area A8 on the sheet film 201 to the surface S5 of the material 202. First, the eleventh linear actuator 73 drives the first measuring roller translation frame 75 to move closer to the material 202, and the twelfth linear actuators 74 on the front and rear sides drive the corresponding second measuring roller translation frame 76 to move closer to the material 202. This causes the measuring roller cylinders 79 on the front and rear sides to roll the areas A5 and A8 of the sheet film 201 onto the surfaces S4 and S5 of the material 202. The elastic force of the elastic members 78 on the front and rear sides pushes the third measuring roller translation frame 77 on the front and rear sides towards the measuring roller clamping and positioning mechanism 72. This ensures that the measuring roller cylinders 79 on the front and rear sides can maintain rolling on the surfaces S4 and S5 of the material 202, so that the areas A5 and A8 of the sheet film 201 are completely attached to the surfaces S4 and S5 of the material 202.

[0087] Please see Figure 3 In detail, the coating equipment 100 of this application also includes a second transfer device 80d, which transfers the material 202 that has been pressed on the upper and lower sides of the sheet film 201 on the side scraping mechanism 60 to the side rolling mechanism 70. It should be noted that the specific structure and working principle of the second transfer device 80d are well known to those skilled in the art. For example, a transfer robot or other technical solutions can be used, which are all conventional technical means. Therefore, they will not be described in detail here.

[0088] Please see Figures 1 to 5The film supply device 20 further includes: a web-aligning translation frame 24, a web-aligning translation drive mechanism 25, a web-aligning detection sensor 26, and a release paper winding mechanism 27. The web-aligning translation frame 24 is movably mounted on the frame 10 in the front-back direction, and the web-aligning translation drive mechanism 25 is fixed on the frame 10 in the front-back direction. The web-aligning translation frame 24 is drively connected to the web-aligning translation drive mechanism 25, and the unwinding mechanism 21 is mounted on the web-aligning translation frame 24. The web-aligning detection sensor 26 is mounted on the frame 10, and the web-aligning detection sensor 26 is located between the unwinding mechanism 21 and the film preparation mechanism 22 along the transmission direction of the strip film 200. The strip film 200 is transmitted through the detection area of ​​the correction detection sensor 26. When the correction detection sensor 26 detects that the transmission position of the strip film 200 deviates from the preset position, the correction translation drive mechanism 25 drives the correction translation frame 24 to move in the front-back direction to adjust the transmission position of the strip film 200 and prevent the transmission position of the strip film 200 from shifting in the front-back direction, making the structure safer and more reliable. It should be noted that the specific structure and working principle of the correction translation drive mechanism 25 are well known to those skilled in the art. For example, a drive structure that uses a motor to drive the lead screw to rotate and drive the lead screw nut to move, or a cylinder drive, are all conventional technical means, and therefore will not be described in detail here.

[0089] Furthermore, the release paper winding mechanism 27 is mounted on the web guiding and translation frame 24. The release paper 203, torn off from the unwinding mechanism 21 after the strip film 200 is output, is guided and wound onto the release paper winding mechanism 27 via a roller. In this embodiment, the unwinding mechanism 21 passively pulls and unwinds the strip film 200, while the release paper winding mechanism 27 is actively wound up the release paper 203 torn off the strip film 200 by a motor. The specific structures and working principles of the unwinding mechanism 21 and the release paper winding mechanism 27 are well known to those skilled in the art and are conventional techniques; therefore, they will not be described in detail here.

[0090] Please see Figures 3 to 5 and Figure 11The coating equipment 100 of this application also includes a waste film recycling mechanism 90 disposed on the frame 10. After the strip film 200 rolled up on the unwinding mechanism 21 is output, it is necessary to replace it with another roll of strip film 200. The two strip films 200 need to be bonded together by adhesive tape. However, the part of the two strip films 200 bonded together by adhesive tape needs to be cut off. The waste film recycling mechanism 90 can recycle the part of the two strip films 200 bonded together by adhesive tape. The waste film recycling mechanism 90 includes: a waste film recycling mounting frame 91, a pressure roller 92, a thirteenth linear actuator 93, a waste film recycling lifting frame 94, an opening and closing actuator 95a, a first clamping plate 95b, a second clamping plate 95c, a fourteenth linear actuator 96, a waste film recycling translation frame 97, a rotary actuator 98, and a rotary hanger 99. The waste film recycling mounting frame 91 is fixed to the frame 10, and the pressure roller 92 is pivotally connected to the waste film recycling mounting frame 91 in the front-to-back direction. The thirteenth linear actuator 93 can be a cylinder, but is not limited to it. The thirteenth linear actuator 93 is vertically fixed to the waste film recycling mounting frame 91, and the waste film recycling lifting frame 94 is vertically movable on the waste film recycling mounting frame 91. The waste film recycling lifting frame 94 is fixedly connected to the drive end of the thirteenth linear actuator 93, and is driven by the thirteenth linear actuator 93 to move the waste film recycling lifting frame 94 vertically up and down. The opening and closing actuator 95a can be selected as a two-finger translational gripper, but is not limited thereto. The opening and closing actuator 95a is vertically fixed on the waste film recycling lifting frame 94. The first clamping plate 95b and the second clamping plate 95c are fixed one-to-one on the two opening and closing drive ends of the opening and closing actuator 95a. The opening and closing directions of the two opening and closing drive ends of the opening and closing actuator 95a are arranged in the left and right directions. The fourteenth linear actuator 96 can be selected as a cylinder, but is not limited thereto. The fourteenth linear actuator 96 is fixed in the left and right directions on the waste film recycling mounting frame 91. The waste film recycling translation frame 97 is movable in the left and right directions on the waste film recycling mounting frame 91. The waste film recycling translation frame 97 is fixedly connected to the drive end of the fourteenth linear actuator 96. The rotary actuator 98 can be selected as a motor, but is not limited thereto. The rotary actuator 98 is fixed on the waste film recycling translation frame 97. The rotary bracket 99 is pivotally connected to the waste film recycling translation frame 97 in the front and back directions. The rotary bracket 99 is drively connected to the drive end of the rotary actuator 98. The first clamping plate 95b and the second clamping plate 95c are located below the pressure roller 92, which is located below the film pulling rod 235, and the rotating bracket 99 is located to the right of the pressure roller 92.Then, when the upper ends of the two strip films 200 with adhesive tape adhering to their ends are cut by the cutting mechanism 30, they remain adhered to the film-pulling rod 235 and are driven downwards by the film-pulling rod 235 until they descend between the first clamping plate 95b and the second clamping plate 95c. The opening and closing driver 95a drives the first clamping plate 95b and the second clamping plate 95c to clamp the lower ends of the cut portions of the two strip films 200 with adhesive tape adhering to their ends, so that the cut portions of the two strip films 200 with adhesive tape adhering to their ends are hung between the film-pulling rod 235 and the first clamping plate 95b and the second clamping plate 95c. Then, the fourteenth linear driver 96 drives the waste film recycling translation frame 97 to the left. The movement causes the rotating bracket 99 to move closer to the pressure roller 92 until the pressure roller 92 pushes and adheres the cut portions of the two strip films 200 with adhesive paper attached to their ends onto the rotating bracket 99. At this time, the opening and closing driver 95a drives the first clamping plate 95b and the second clamping plate 95c to open and release the lower ends of the cut portions of the two strip films 200 with adhesive paper attached to their ends. Then, the rotating driver 98 drives the rotating bracket 99 to rotate so that the cut portions of the two strip films 200 with adhesive paper attached to their ends are rolled up on the rotating bracket 99, avoiding the messy stacking of the cut portions of the two strip films 200 with adhesive paper attached to their ends, making the structure more reasonable.

[0091] The working principle of the coating equipment 100 is explained in detail below with reference to the attached drawings:

[0092] First, the rolled strip film 200 is placed on the film supply device 20, and then the film preparation mechanism 22 pulls the strip film 200 out. The release paper 203 that is torn off after the strip film 200 is output from the unwinding mechanism 21 is guided by the roller and wound onto the release paper winding mechanism 27.

[0093] Then, the film-pulling mechanism 23 pulls the strip film 200 downwards to the entrance of the coating area 11. The feeding robot 80a then pushes the material 202, located at the entrance of the coating area 11, into the coating area 11. As the material 202 passes through the coating area 11, the pressing mechanism 40 presses the strip film 200 located in the coating area 11 onto the upper and lower surfaces of the material 202. Finally, the cutting mechanism 30 presses the strip film 200 onto the material 202. The lower surface portion is cut out to form a sheet film 201 covering the upper and lower surfaces of the material 202. Then, the material 202 covered with the sheet film 201 is picked up by the material handling robot 80b, moved out of the coating area 11 and transferred to the side cutting mechanism 50. The side cutting mechanism 50 cuts the sheet film 201 between regions A4 and A5, between regions A5 and A6, between regions A7 and A8, and between regions A8 and A9.

[0094] Then, the material 202 that has been side-cut on the sheet film 201 by the first transfer device 80c is transferred to the side scraping mechanism 60, and the side scraping mechanism 60 scrapes the areas A6 and A9 of the sheet film 201 upward onto the corresponding surfaces S4 and S5 of the material 202.

[0095] Then, the second transfer device 80d moves the material 202, which has been pressed on the upper and lower sides of the sheet film 201 on the side scraping mechanism 60, to the side rolling mechanism 70. The side rolling mechanism then completely attaches the areas A5 and A8 of the sheet film 201 to the surfaces S4 and S5 of the material 202, thereby completing the coating process of the material 202.

[0096] When the unwinding mechanism 21 finishes outputting the rolled strip film 200, and another rolled strip film 200 is put on, the cut portion of the two strip films 200 with adhesive paper attached to their ends is wound up onto the waste film recycling mechanism 90.

[0097] For example, the material 202 used for coating processing by the coating equipment 100 of this application can be a lithium battery, that is, the rolled strip film 200 is cut and attached to the lithium battery to complete the coating processing of the lithium battery. Of course, the material 202 used for coating processing by the coating equipment 100 of this application can also be selected as other types of products according to actual use needs, all of which are within the protection scope of this application, so they will not be described in detail here.

[0098] Since the coating equipment 100 of this application has a coating area 11 distributed on the frame 10, the film supply device 20 carries the rolled strip film 200 and outputs it to the entrance of the coating area 11. The feeding robot 80a pushes the material 202 to move the strip film 200 located at the entrance of the coating area 11 into the coating area 11. The pressing mechanism 40 presses the strip film 200 located in the coating area 11 onto the upper and lower surfaces of the material 202 that has passed through the coating area 11. The cutting mechanism 30 cuts out the part of the strip film 200 pressed onto the upper and lower surfaces of the material 202 to form a sheet film 201 covering the upper and lower surfaces of the material 202. The picking robot 80b receives the material 202 covered with the sheet film 201 from the feeding robot 80a and moves it out of the coating area 11. The rolled strip film 200 is placed on the film supply device 20, and then the film supply device 20 outputs the strip film 200 to the entrance of the coating area 11. Then, the feeding robot 80a pushes the material 202 at the entrance of the coating area 11 and moves the strip film 200 into the coating area 11. During the process of the material 202 passing through the coating area 11, the pressing mechanism 40 presses the strip film 200 in the coating area 11 onto the upper and lower surfaces of the material 202. Then, the cutting mechanism 30 cuts out the part of the strip film 200 pressed onto the upper and lower surfaces of the material 202 to form a sheet film 201 covering the upper and lower surfaces of the material 202. Then, the picking robot 80b picks up the material 202 covered with the sheet film 201 from the feeding robot 80a and moves it out of the coating area 11. With its simple structure, it achieves automated coating without the need for human intervention, and greatly improves coating efficiency. It avoids the impact of human instability on coating quality, thus better ensuring coating quality and better adapting to the needs of mass production and high-efficiency processing.

[0099] The present application has been described above with reference to the embodiments, but the present application is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations made in accordance with the nature of the present application.
