DETAILED DESCRIPTION

[0064] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0065] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described here can be implemented in an order other than those illustrated or described here. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0066] Next, a coating device according to an embodiment of the present invention will be described.

[0067] like Figure 1 As shown, the coating device according to the embodiment of the present invention includes a turntable 110 , two sets of adsorption platforms 120 , a loading device 200 and a coating device 300 .

[0068] First, the turntable 110 and the two groups of adsorption platforms 120 are explained. The turntable 110 is rotatable, and a relatively arranged loading station and coating station are formed on the turntable 110. The two groups of adsorption platforms 120 are arranged on the turntable 110, and are respectively located at the loading station and the coating station. The turntable 110 can drive the adsorption platforms 120 to rotate, so that the adsorption platforms 120 can be switched between the loading station and the coating station. Each group of adsorption platforms 120 includes at least one adsorption platform 120, and the adsorption platform 120 is used to carry the battery cell. It should be noted here that the number of adsorption platforms 120 in the two groups of adsorption platforms 120 arranged on the turntable 110 needs to be the same, and the positions are set correspondingly, so that each time the turntable 110 rotates, the two groups of adsorption platforms 120 can be accurately switched between the loading station and the gluing station.

[0069] Optionally, each group of adsorption platforms 120 includes two, three or four adsorption platforms 120. Each adsorption platform 120 can adsorb one battery cell, that is, multiple battery cells can be loaded or coated simultaneously, which can improve efficiency and increase production capacity.

[0070] like Figure 2 As shown, two groups of adsorption platforms 120 are arranged on the turntable 110, and each group of adsorption platforms 120 includes three adsorption platforms 120. Figure 3As shown, two groups of adsorption platforms 120 are arranged on the turntable 110, and each group of adsorption platforms 120 includes two adsorption platforms 120. The turntable 110 can drive the adsorption platforms 120 to switch between the loading station and the coating station, that is, during the loading process at the loading station, the coating station performs the coating operation synchronously, which can improve efficiency.

[0071] In other embodiments, multiple groups of adsorption platforms 120, that is, more than two groups of adsorption platforms 120, can be arranged on the turntable 110. In addition to the loading station and the coating station, other stations can be arranged on the turntable 110 according to actual needs. Each station is correspondingly provided with a group of adsorption platforms 120, and all stations can operate synchronously. These should all be understood within the scope of the present utility model.

[0072] Next, the loading device 200 and the coating device 300 are described. The loading device 200 is disposed adjacent to the loading station of the turntable 110, and the loading device 200 can transfer the battery cells to the adsorption platform 120 located at the loading station. The coating device 300 is disposed adjacent to the coating station of the turntable 110, and the coating device 300 can coat the battery cells carried on the adsorption platform 120.

[0073] The loading device 200 transfers the battery cells to the adsorption platform 120 of the loading station, and the turntable 110 rotates to move the adsorption platform 120 of the loading station to the coating station. During the rotation of the turntable 110, the adsorption platform 120 located at the coating station moves to the loading station, and the coating device 300 coats the battery cells. After the coating is completed, the battery cells are unloaded, and then the turntable 110 rotates again, and this reciprocating process can efficiently load and coat the battery cells.

[0074] Specifically, when only the loading station and the coating station are set on the turntable 110, the turntable 110 can rotate clockwise, or counterclockwise, or alternately clockwise and counterclockwise each time during operation; when multiple stations are set on the turntable 110, the turntable 110 can rotate clockwise, or counterclockwise each time during operation.

[0075] In the above coating equipment, the turntable 110 carries two groups of adsorption platforms 120, each group of adsorption platforms 120 includes one or more adsorption platforms 120 that can adsorb battery cells, the loading device 200 can transfer one or more battery cells to the adsorption platform 120 of the loading station, and the coating device 300 can synchronously coat one or more battery cells on the adsorption platform 120 of the coating station. The turntable 110 carries the adsorption platform 120 to switch between the loading station and the coating station, and can perform loading operations and coating operations simultaneously, with high efficiency and large production capacity. It should be noted here that the number of battery cells adsorbed by each group of adsorption platforms 120 needs to be the same. Specifically, the number of each group of adsorption platforms 120 is not less than the number of battery cells adsorbed, that is, each group of adsorption platforms 120 is provided with a preset number of adsorption platforms 120 to adsorb the same preset number of battery cells, or each group of adsorption platforms 120 is provided with multiple adsorption platforms 120 to adsorb a small number of battery cells, and the extra adsorption platforms 120 can turn off the adsorption function to cope with battery cell coating operations with different quantity requirements.

[0076] According to some embodiments of the utility model, the adsorption platform 120 includes a table top and an adjustment mechanism connected under the table top, and the adjustment mechanism is capable of adjusting the position of the table top. The coating equipment also includes: a first camera 420 and an alignment system. The first camera 420 is arranged above the loading station of the turntable 110, and the first camera 420 is capable of capturing a first image of the battery cell on the adsorption platform 120 located on the loading station. The alignment system connects the first camera 420 and the adjustment mechanism to control the adjustment mechanism to adjust the position of the table top according to the difference between the first image and the predetermined image, and the predetermined image corresponds to the coating area of ​​the coating device 300.

[0077] The adjustment mechanism may be an XYθ platform or a UVW platform. The position of the tabletop can be adjusted by the alignment mechanism.

[0078] like Figure 1 As shown, the first camera 420 is arranged on the crossbeam of the gantry 410, and the first camera 420 collects the first image of the battery cell at the loading station. The alignment system adjusts the position of the table through the adjustment mechanism so that the difference between the first image (the image of the battery cell on the table) and the predetermined image is less than a predetermined threshold value. When the turntable 110 rotates, the adsorption platform 120 switches from the loading station to the coating station, and the coating area of ​​the coating station corresponds to the predetermined image. Since precise alignment has been performed at the loading station, the coating device 300 can accurately coat the battery cell. The alignment action is performed when the coating device 300 is coating the previous battery cell, thereby improving efficiency.

[0079] In some embodiments of the present invention, the coating device further includes a second camera 430 and a processor. The second camera 430 is disposed above the loading station of the turntable 110 and is used to collect a second image of the battery cell. The processor is connected to the second camera 430 to determine whether the battery cell is a fragment according to the second image.

[0080] The coating equipment also includes a light source assembly, which is arranged below the loading station of the turntable 110 and is used to provide light for the battery cell on the loading station to improve the imaging effect of the second camera 430 and to determine whether cracks appear in the battery cell based on the second image.

[0081] In other embodiments, the second camera 430 may also be disposed above the coating station of the turntable 110 to collect a second image of the battery cell. The processor is connected to the second camera 430 to determine whether the battery cell is a fragment according to the second image. If the battery cell is a fragment, it can be directly unloaded at the coating station.

[0082] like Figure 1 As shown, the second camera 430 is set on the crossbeam of the gantry 410 and is located above the loading station of the turntable 110. The second camera 430 and the processor can detect the fragments of the adsorption platform 120, so as to facilitate timely relevant actions (pause the operation of the equipment and alarm, timely pick up the fragments to the outside of the adsorption platform 120, etc.), avoid coating the fragments and cause the coated screen to break. Furthermore, the light source assembly is located below the loading station of the turntable 110. The light source assembly, the second camera 430 and the processor can detect the hidden cracked battery cells of the adsorption platform 120, so as to facilitate timely relevant actions and unloading, avoid coating the cracked battery cells, and cause waste of the coating process.

[0083] Furthermore, a sheet of breathable table paper is laid on the adsorption platform 120, and the adsorption platform 120 carries the battery cell through the table paper. The second camera 430 is also used to collect the paper image of the table paper. The processor also determines whether the table paper meets the predetermined appearance requirements based on the paper image.

[0084] like Figure 1 When the turntable 110 moves the adsorption platform 120 to the loading station, the second camera 430 and the processor determine whether the table paper meets the predetermined appearance requirements. If it does, the loading action can be performed. If it does not meet the predetermined appearance requirements (such as wrinkles, dirt, damage, foreign matter, and the size of the outline is smaller than the size of the battery cell, etc.), it can be replaced to avoid loading the battery cell onto the table paper that meets the predetermined appearance requirements, which may cause the battery cell to be contaminated, the battery cell coating accuracy is poor, and the battery cell is broken. It should be noted that if the table paper is laid on the adsorption platform 120, the second camera 430 needs to be set above the loading station of the turntable 110.

[0085] In some embodiments of the present invention, the loading device 200 includes a suction cup 220 and a loading moving mechanism 210. The number of the suction cups 220 is consistent with the number of the adsorption platforms 120 located at the loading station, the suction cups 220 are used to adsorb the battery cells, or the suction cups 220 are used to adsorb the battery cells and the table paper, and the loading moving mechanism 210 drives the suction cups 220 to move.

[0086] The loading moving mechanism 210 may be a linear module.

[0087] It can be understood that the feeding device 200 has a first working state and a second working state. In the first working state, the feeding moving mechanism 210 can drive the suction cup 220 to absorb the battery cell to transfer the battery cell to the absorption platform 120 located at the feeding station. In the second working state, the feeding moving mechanism 210 can drive the suction cup 220 to absorb the table paper to transfer the table paper to the absorption platform 120 located at the feeding station. The feeding device 200 has both the feeding function of the battery cell and the feeding function of the table paper, so that the coating equipment structure is simple.

[0088] In other equivalent embodiments, the adsorption platform 120 may not be disposed on the turntable 110, for example, it may be disposed on a linear drive mechanism, and the linear drive mechanism can drive the adsorption platform 120 to move to the loading station and the coating station. The adsorption platform 120 may also be fixed, and the loading station and the coating station are located at the same position.

[0089] like Figure 3 As shown, two suction cups 220 adsorb two battery cells, and the loading moving mechanism 210 also includes two. The two loading moving mechanisms 210 respectively drive the two suction cups 220 to move, thereby moving the two battery cells to the two adsorption platforms 120 of the loading station.

[0090] It should be noted that the above are only optional examples, and the two suction cups 220 can also move two pieces of table paper to the adsorption platform 120. The adsorption platform 120 of the loading station can also include three or four, and the corresponding suction cups 220 are also three or four. The loading moving mechanism 210 can also include only one, and one loading moving mechanism 210 drives the two suction cups 220 to move. These should all be understood within the scope of the present utility model.

[0091] Furthermore, the coating device also includes a paper carrier 500, which includes a first paper carrier, a second paper carrier, a paper carrier moving mechanism 520 and a controller. The first paper carrier and the second paper carrier are arranged adjacent to each other and are both used to carry table paper. Multiple unused table paper can be stacked on the first paper carrier. The paper carrier moving mechanism 520 connects the first paper carrier and the second paper carrier to synchronously drive the first paper carrier and the second paper carrier to move and switch between a first position and a second position. In the first position, the suction cup 220 can transfer the table paper in the first paper carrier to the adsorption platform 120. In the second position, the suction cup 220 can transfer the table paper on the adsorption platform 120 to the second paper carrier. The controller is connected to the processor, the loading device 200 and the paper carrier moving mechanism 520, so as to control the paper carrier moving mechanism 520 to move the first paper carrier and the second paper carrier to the second position according to the processor determining that the table paper does not meet the predetermined appearance requirements, and control the loading device 200 to transfer the table paper on the adsorption platform 120 to the second paper carrier. Then, the controller controls the paper carrier moving mechanism 520 to move the first paper carrier and the second paper carrier to the first position, and controls the loading device 200 to transfer the unused table paper in the first paper carrier to the adsorption platform 120.

[0092] It can be understood that the loading device 200 also has a third working state, and the loading moving mechanism 210 can drive the suction cup 220 to transfer the table paper on the adsorption platform 120. The loading device 200 has both the loading function of the battery cell and the loading and unloading function of the table paper, making the coating equipment structure simple.

[0093] Specifically, in the second working state, the loading moving mechanism 210 drives the suction cup 220 to adsorb the table paper to transfer the table paper to the adsorption platform 120 located at the loading station; in the first working state, the loading moving mechanism 210 drives the suction cup 220 to adsorb the table paper in the first paper carrier (located in the first position) to the adsorption platform 120; in the third working state, the loading moving mechanism 210 drives the suction cup 220 to adsorb the table paper on the adsorption platform 120 to the second paper carrier (located in the second position).

[0094] The paper carrier moving mechanism 520 may be a linear module.

[0095] like Figure 4 As shown, the paper loading device 500 includes four paper loading seats, two first paper loading seats, and two second paper loading seats. The first paper loading seats are used to hold multiple unused table paper. The second paper loading seats are used to hold table paper that does not meet the predetermined appearance requirements.

[0096] The processor determines that the table paper laid on the adsorption platform 120 does not meet the predetermined appearance requirements, and the controller controls the paper carrier moving mechanism 520 to move the first paper carrier and the second paper carrier to the second position (the position where the suction cup 220 can pass through the second paper carrier), and the feeding moving mechanism 210 of the feeding device 200 drives the suction cup 220 to move to the top of the adsorption platform 120, and the suction cup 220 sucks up the table paper that does not meet the predetermined appearance requirements, and the feeding moving mechanism 210 moves the suction cup 220 to the position of the second paper carrier, and the suction cup 220 0 puts down the sucked table paper to the second paper carrier, the controller controls the paper carrier moving mechanism 520 to move the first paper carrier and the second paper carrier to the first position (the position where the suction cup 220 can pass through the first paper carrier), the suction cup 220 moves to absorb the unused table paper in the first paper carrier, the feeding moving mechanism 210 moves the suction cup 220 to the position of the absorption platform 120, the suction cup 220 puts down the table paper, and the absorption platform 120 absorbs the table paper, thereby realizing the automatic replacement of the table paper and improving the replacement efficiency of the table paper.

[0097] Further, the first paper carrier includes a first paper carrier 513 and a plurality of first positioning rods 511. The first paper carrier 513 is used to carry the table paper. The plurality of first positioning rods 511 are arranged around the first paper carrier 513. The second paper carrier includes a second paper carrier 514 and a plurality of second positioning rods 512.

[0098] The paper carrier 500 further includes a moving plate 530 and a support column 553. The moving plate 530 is connected to the lower part of the first paper carrier and the second paper carrier through the support column 553. The first paper carrier 513, the second paper carrier 514 and the moving plate 530 can move horizontally synchronously. The paper carrier moving mechanism 520 is connected to the moving plate 530, and the first paper carrier 513 and the second paper carrier 514 are moved through the moving plate 530. The first paper carrier 513 and the second paper carrier 514 can be integrally formed or arranged adjacent to each other.

[0099] like Figure 4 As shown, the first paper carrier and the second paper carrier are an integrally formed plate, and a simple first paper carrier can be formed by a first paper carrier 513 and a plurality of first positioning rods 511, and a simple second paper carrier can be formed by a second paper carrier 514 and a plurality of second positioning rods 512. The paper carrier moving mechanism 520 is connected to the moving plate 530, and drives the moving plate 530 to move horizontally. Due to the driving of the support column 553, the first paper carrier 513 and the second paper carrier 514 can move synchronously with the moving plate 530, so that the first paper carrier 513 and the second paper carrier 514 can move back and forth between the first position and the second position.

[0100] It should be noted that the above are only optional examples, and the first paper carrier 513 and the second paper carrier 514 can also be two boards that can be arranged adjacent to each other, which should be understood to be within the scope of the present utility model.

[0101] In some embodiments of the present invention, the paper carrier 500 further includes a first lifting plate 541 and a first lifting mechanism 542. The first lifting plate 541 is disposed below the movable plate 530, and a plurality of first positioning rods 511 pass through the first paper carrier 513 and the movable plate 530 from top to bottom to the first lifting plate 541, and the first lifting plate 541 can be lifted and lowered synchronously with the plurality of first positioning rods 511. The first lifting mechanism 542 is connected to the first lifting plate 541 to drive the first lifting plate 541 to lift and lower. The first lifting mechanism 542 includes a motor or a cylinder 331c.

[0102] like Figure 4 As shown, the first lifting mechanism 542 drives the first lifting plate 541 to rise and fall, and the first lifting plate 541 drives the multiple first positioning rods 511 to rise and fall synchronously. During the process of the suction cup 220 sucking the table paper from the first paper carrier, the distance between the suction cup 220 and the table paper is small. In order to avoid the interference of the first positioning rod 511 on the suction cup 220, the first positioning rod 511 can be lowered, so that the suction cup 220 can stably suck up the table paper from the first paper carrier. Moreover, the lifting and lowering of the first positioning rod 511 can also facilitate the addition of new table paper.

[0103] In some embodiments of the present invention, the paper carrier 500 further includes a second lifting plate 551 and a second lifting mechanism 552. The second lifting plate 551 is disposed below the movable plate 530, the first end of the support column 553 is connected to the bottom ends of the first paper carrier 513 and the second paper carrier 514, the support column 553 passes through the movable plate 530 and the second end thereof is connected to the second lifting plate 551, and the second lifting plate 551 can move synchronously with the support column 553. The second lifting mechanism 552 is connected to the second lifting plate 551 to drive the second lifting plate 551 to rise and fall. The second lifting mechanism 552 includes a motor or a cylinder 331c.

[0104] like Figure 4 As shown, the second lifting mechanism 552 drives the second lifting plate 551 to move up and down, the second lifting plate 551 drives the support column 553 to move up and down, and the support column 553 drives the first paper carrier 513 and the second paper carrier 514 to move up and down. When the suction cup 220 cannot move up and down (to ensure the height stability of the suction cup 220), in order to make the gap between the suction cup 220 and the table paper a predetermined gap (the gap that the suction cup 220 can absorb the table paper), the first paper carrier 513 is driven to move up and down by the second lifting mechanism 552, and the table paper moves up and down following the first paper carrier 513, so that the gap between the table paper and the suction cup 220 can be the predetermined gap.

[0105] In some embodiments of the present invention, the coating device 300 includes a screen holder 310 , a scraper assembly 330 , an ink return blade assembly 320 , a coating moving mechanism 340 , and a coating lifting mechanism 360 .

[0106] The screen holder 310 is formed with a slot that can accommodate the screen. The scraper assembly 330 and the ink return knife assembly 320 are arranged above the slot. The scraper assembly 330 and the ink return knife assembly 320 cooperate to transfer the coating glue on the screen to the battery cell carried on the adsorption platform 120. The coating moving mechanism 340 connects the scraper assembly 330 and the ink return knife assembly 320 to drive the scraper assembly 330 and the ink return knife assembly 320 to move. The coating lifting mechanism 360 is connected to the screen holder 310 to drive the screen holder 310 to rise and fall.

[0107] like Figure 5 As shown, a screen is inserted into the slot of the screen holder 310. When working, the coating glue is poured onto the screen, and the coating moving mechanism 340 drives the scraper assembly 330 and the ink return knife assembly 320 to move horizontally. The scraper assembly 330 and the ink return knife assembly 320 cooperate with each other to transfer the coating glue to the battery cell.

[0108] The coating lifting mechanism 360 lifts the screen holder 310 , and the screen follows the screen holder 310 to rise and fall, so that the screen has a predetermined screen gap from the adsorption platform 120 , and the coating glue can be transferred to the predetermined area of ​​the battery cell more accurately.

[0109] like Figure 6 As shown, the scraper assembly 330 includes a scraper 332 and a first driving mechanism 331, and the scraper 332 is driven to rise and fall by the first driving mechanism 331. The ink return knife assembly 320 includes an ink return knife 322 and a second driving mechanism 321, and the ink return knife 322 is driven to rise and fall by the second driving mechanism 321.

[0110] In some embodiments of the present invention, when a group of adsorption platforms 120 includes a plurality of adsorption platforms 120 spaced apart from each other, the coating device 300 may have the following two structures:

[0111] Structure 1: A slot is provided on the screen holder 310 , and a plurality of spaced-apart coating patterns are formed on the screen accommodated in the slot, and the plurality of coating patterns correspond to the plurality of adsorption platforms 120 one by one.

[0112] For example, a group of adsorption platforms 120 includes four adsorption platforms 120, each adsorption platform 120 adsorbs a battery cell to the coating station, and four coating patterns are formed on the mesh of a screen, and four battery cells can be coated at the same time.

[0113] Structure 2: A plurality of slots are spaced apart on the screen holder 310, one slot corresponds to one scraper assembly 330 and one ink return knife assembly 320, and each slot can accommodate one screen.

[0114] like Figure 5 As shown, a group of adsorption platforms 120 includes two adsorption platforms 120, two slots are arranged at intervals on the screen vertically, the two slots accommodate two screens, and a scraper assembly 330 and an ink return knife assembly 320 are arranged on each screen.

[0115] Compared with structure 2, structure 1 has a relatively simple coating device 300 structure, and the number of screens is also small, which can save costs. Compared with structure 1, structure 2 can coat each battery cell on the adsorption platform 120 relatively independently, which is convenient for adjustment and improves coating stability.

[0116] In some embodiments of the present invention, the coating moving mechanism 340 includes a translation mechanism 341 and a support frame 342. The translation mechanism 341 is arranged on one or both sides of the screen holder 310 in the horizontal direction. The support frame 342 is arranged above the screen holder 310, and the coating moving mechanism 340 is connected to the scraper assembly 330 and the ink return knife assembly 320 through the support frame 342. The support frame 342 is also connected to the translation mechanism 341, and the translation mechanism 341 can move the support frame 342 longitudinally.

[0117] like Figure 5 As shown, the translation mechanism 341 is a linear motor module arranged on both sides of the screen holder 310 horizontally, and a support frame 342 is arranged above the translation mechanism 341 to drive the support frame 342 to move longitudinally. The scraper assembly 330 and the ink return knife assembly 320 are arranged on the support frame 342 and move synchronously with the support frame 342.

[0118] It should be noted that the above are only optional examples. The support frame 342 can be connected to the top of the screen holder 310 through a track and a slider. The translation mechanism 341 is set on the side of the support frame 342 and connected to the slider, thereby driving the support frame 342 to move longitudinally. These should all be understood to be within the scope of the present utility model.

[0119] In some embodiments of the present invention, the screen holder 310 includes a first slot and a second slot that are laterally spaced apart, and the coating equipment includes a first height measuring device 351 and a second height measuring device 352. The first height measuring device 351 and the second height measuring device 352 are both arranged on the support frame 342. The first height measuring device 351 faces the first slot to measure a first distance between it and the screen accommodated in the first slot, and the second height measuring device 352 faces the second slot to measure a second distance between it and the screen accommodated in the second slot.

[0120] like Figure 5As shown, the first height measuring device 351 tests the first distance, and the second height measuring device 352 tests the second distance, so that the height difference between the screen contained in the first slot and the screen contained in the second slot can be known, which is convenient for relevant personnel to make corresponding adjustments, adjust the screens so that the first screen and the second screen are kept at the same level, or adjust the height of the adsorption platform 120 so that the distance between the first screen and the second screen and the adsorption platform 120 is consistent.

[0121] Furthermore, the coating device 300 further includes a first screen adjustment mechanism 361 and / or a second screen adjustment mechanism 362. The first screen adjustment mechanism 361 is disposed near the first slot and is used to adjust the height of the screen accommodated in the first slot. The second screen adjustment mechanism 362 is disposed near the second slot and is used to adjust the height of the screen accommodated in the second slot.

[0122] The first screen adjustment mechanism 361 and the second screen adjustment mechanism 362 can be mechanisms such as cylinders, micro motors or adjustment bolts that can adjust the screen height up and down.

[0123] The first screen adjustment mechanism 361 and the second screen adjustment mechanism 362 can make the height of the screen in the first slot and the screen in the second slot consistent (the mesh cloths of the screens are coplanar), so that the printing effects of two adsorption platforms 120 in a group of adsorption platforms 120 can be kept consistent.

[0124] In some embodiments of the present invention, the scraper assembly 330 includes a scraper 332 and a first driving mechanism 331. The first driving mechanism 331 is connected to the scraper 332 to drive the scraper 332 to perform lifting motion. The first driving mechanism 331 includes a motor module 331a and a pressure sensor 331b, and the pressure sensor 331b is used to detect the force applied by the motor module 331a to the scraper 332, or the first driving mechanism 331 includes a cylinder 331c and a proportional valve 331d, and adjusting the proportional valve 331d can adjust the thrust of the cylinder 331c.

[0125] like Figure 6 and Figure 7 As shown, the scraper assembly 330 has two structures.

[0126] Structure 1, such as Figure 7 As shown in the middle left figure, the motor module 331a drives the scraper 332 to rise and fall, and the force applied to the scraper 332 by the motor module 331a is detected by the pressure sensor 331b. The force applied to the scraper 332 by the motor module 331a corresponds to the force applied to the screen and the battery cell by the scraper 332, which makes it easy for the user to accurately adjust the force applied by the motor to the scraper (adjust the height of the scraper 332), thereby improving the coating effect of the battery cell and increasing the stability of the coating.

[0127] Structure 2, such as Figure 7 As shown in the middle right figure, the cylinder 331c drives the scraper 332 to rise and fall, and the thrust of the cylinder 331c, that is, the force applied by the cylinder 331c to the scraper 332, is adjusted by the proportional valve 331d. This is convenient for accurately adjusting the force (the size of the air pressure) applied by the cylinder 331c to the scraper 332, thereby improving the coating effect of the battery cell and increasing the stability of the coating.

[0128] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
