[0040] Reference Figure 1 as well as Figure 2 As shown, the coating equipment involved in the embodiment of the present application is used to coat an electrode plate. The electrode plate has a first coating surface (not shown) and a second coating surface (not shown). The coating equipment includes: a coating device 100 and a feeding device 200.

[0041] Specifically, the coating device 100 includes a driving component 110, a first coating component 120 and a second coating component 130. The first coating component 120 is arranged on a side of the electrode plate close to the first coating surface along the first direction, and the second coating component 130 is arranged on a side of the electrode plate close to the second coating surface along the first direction, and the first coating component 120 and the second coating component 130 are both connected to the driving component 110. The driving component 110 drives the first coating component 120 and the second coating component 130 to move along the second direction relative to the electrode plate. The first coating component 120 has a third coating surface 121, and the third coating surface 121 is arranged parallel to the first coating surface. The second coating component 130 has a fourth coating surface 131, and the fourth coating surface 131 is arranged parallel to the second coating surface; the feeding device 200 is used to provide coating to the first coating component 120 and the second coating component 130; wherein the first direction is perpendicular to the second direction.

[0042] It should be noted that the first direction is Figure 2 The direction indicated by x is the thickness direction of the electrode plate, and the second direction is Figure 2 The direction indicated by y is the height direction of the electrode plate.

[0043] In the above-mentioned coating equipment, the coating can be provided to the first coating component 120 and the second coating component 130 through the feeding device 200, and the first coating surface of the electrode plate is coated through the third coating surface 121 of the first coating component 120, and the second coating surface of the electrode plate is coated through the fourth coating surface 131 of the second coating component 130. Since the first coating component 120 and the second coating component 130 are both connected to the driving component 110, the driving component 110 drives the first coating component 120 and the second coating component 130 to move in the second direction relative to the electrode plate, therefore, the first coating component 120 and the second coating component 130 can be driven by the driving component 110 to move in the second direction for coating, and it can be ensured that the first coating component 120 and the second coating component 130 are coated. The smoothness of movement during the coating process can be improved to improve the coating surface smoothness of the first coating surface and the second coating surface. Furthermore, since the third coating surface 121 is arranged in parallel with the first coating surface, when the first coating component 120 coats the first coating surface, the contact area between the third coating surface 121 and the coating surface of the first coating surface can be increased, thereby further improving the coating surface smoothness of the first coating surface. Similarly, since the fourth coating surface 131 is arranged in parallel with the second coating surface, when the second coating component 130 coats the second coating surface, the contact area between the fourth coating surface 131 and the coating surface of the second coating surface can be increased, thereby further improving the coating surface smoothness of the second coating surface. In this way, when coating the electrode plate, the above-mentioned coating equipment can improve the flatness of the coating surface.

[0044] Reference Figures 2 to 4 As shown, the coating device 100 also includes a bracket 140, the bracket 140 has a first connecting part 141 and a second connecting part 142, the first connecting part 141 and the second connecting part 142 are arranged at intervals along the first direction, and the first connecting part 141 and the second connecting part 142 are both extended along the second direction, the first coating component 120 is slidably connected to the first connecting part 141, and the first coating component 120 slides along the second direction relative to the first connecting part 141, the second coating component 130 is slidably connected to the second connecting part 142, and the second coating component 130 slides along the second direction relative to the second connecting part 142, and the electrode plate is arranged between the first connecting part 141 and the second connecting part 142.

[0045] It can be understood that the first coating component 120 can slide along the second direction relative to the first connecting portion 141, so as to achieve the movement of the first coating component 120 along the second direction, thereby coating the first coating surface of the electrode plate. Similarly, the second coating component 130 can slide along the second direction relative to the second connecting portion 142, so as to achieve the movement of the second coating component 130 along the second direction, thereby coating the second coating surface of the electrode plate. Furthermore, since the first connecting portion 141 and the second connecting portion 142 are both extended along the second direction, the first connecting portion 141 and the second connecting portion 142 can be arranged in parallel along the second direction, so that the first coating component 120 and the second coating component 130 are parallel in the moving path, thereby improving the consistency of the coating surface of the first coating surface of the electrode plate and the coating surface of the second coating surface, so that the coating surface of the first coating surface and the coating surface of the second coating surface can be parallel.

[0046] Reference Figure 2 as well as Figure 3 As shown, the coating equipment also includes a fixing device 300, which is detachably connected to the bracket 140, and the electrode plate is fixedly connected to the fixing device 300. The fixing device 300 has a fixing plane 310. In the second direction, the symmetric center plane of the first connecting part 141 and the second connecting part 142 coincides with the fixing plane 310, and the center plane of the electrode plate coincides with the fixing plane 310.

[0047] Specifically, in the above-mentioned embodiments, referring to Figure 3 As shown, the fixing device 300 includes a fixing frame 320 , and the electrode plate is fixedly connected to the fixing frame 320 by bolts. The plane on the fixing frame 320 where the electrode plate is fixed is the fixing plane 310 .

[0048] Further, in the above-mentioned embodiment, referring to Figure 3As shown, the bracket 140 also has a third connecting portion 143, the first connecting portion 141 and the second connecting portion 142 are fixedly connected to the third connecting portion 143, and the third connecting portion 143 is arranged between the first connecting portion 141 and the second connecting portion 142, the third connecting portion 143 extends along the second direction, and the third connecting portion 143 is provided with a plurality of connecting holes (not shown) spaced along the second direction, the fixing device 300 also includes a base 330, the fixing frame 320 is fixedly connected to the base 330, and the base 330 is provided with a plurality of connecting members (not shown) spaced along the second direction, each connecting member is passed through a connecting hole to fix the base 330 to the third connecting portion 143, thereby ensuring the parallelism of the fixing plane 310 in the second direction, so as to improve the consistency of the coating surface of the first coating surface of the electrode plate and the coating surface of the second coating surface, so that the coating surface of the first coating surface and the coating surface of the second coating surface can be parallel.

[0049] Specifically, in the above-mentioned embodiments, referring to Figure 3 As shown, the third connection part 143 has a positioning surface 1431 on one side along the first direction, and the symmetric center plane of the first connection part 141 and the second connection part 142 coincides with the positioning surface 1431. When the fixing device 300 is connected to the third connection part 143, the positioning surface 1431 coincides with the center plane of the electrode plate.

[0050] It can be understood that in the second direction, since the symmetry center plane of the first connection part 141 and the second connection part 142 coincides with the fixed plane 310, the center plane of the electrode plate coincides with the fixed plane 310. Therefore, the center plane of the electrode plate can be located on the symmetry center plane of the first connection part 141 and the second connection part 142, so that the first coated surface and the second coated surface of the electrode plate can be symmetrically arranged relative to the symmetry center plane of the first connection part 141 and the second connection part 142, so as to further improve the consistency of the coating surface of the first coated surface and the coating surface of the second coated surface of the electrode plate, so that the coating thickness of the first coated surface is consistent with the coating thickness of the second coated surface.

[0051] Reference Figure 2 as well as Figure 4 As shown, the driving assembly 110 includes a first driving member 111 and a second driving member (not shown). The first driving member 111 and the second driving member are respectively located on both sides of the fixing device 300 along the first direction. The first driving member 111 and the second driving member are both driven and connected to the fixing device 300, and the first driving member 111 and the second driving member both drive the fixing device 300 to move along the first direction.

[0052] Specifically, in the above-mentioned embodiment, the first driving member 111 is disposed on the first connecting portion 141 , and the second driving member is disposed on the second connecting portion 142 .

[0053] It can be understood that, since the first driving member 111 and the second driving member are both connected to the fixing device 300, and the first driving member 111 and the second driving member both drive the fixing device 300 to move along the first direction. Therefore, the first driving member 111 and the second driving member can drive the fixing device 300 to move between the first connecting portion 141 and the second connecting portion 142, so that the electrode plate fixed on the fixing device 300 can move between the first connecting portion 141 and the second connecting portion 142, so as to adjust the position of the electrode plate between the first connecting portion 141 and the second connecting portion 142, and ensure that the center plane of the electrode plate can coincide with the symmetric center plane of the first connecting portion 141 and the second connecting portion 142, so as to further improve the consistency of the coating thickness of the first coating surface and the coating thickness of the second coating surface, and improve the coating accuracy.

[0054] Continue to refer to Figure 2 as well as Figure 4 As shown, the driving assembly 110 also drives the first coating assembly 120 and the second coating assembly 130 to move along the first direction relative to the electrode pad.

[0055] Specifically, in the above-mentioned embodiment, continue to refer to Figure 2 as well as Figure 4 As shown, the driving component 110 also includes a third driving member 112 and a fourth driving member 113. The third driving member 112 is arranged on the first connecting portion 141, and the second driving member is arranged on the second connecting portion 142. The first coating component 120 is drivingly connected to the third driving member 112, and the third driving member 112 drives the first coating component 120 to move along the first direction relative to the electrode plate. The second coating component 130 is drivingly connected to the fourth driving member 113, and the fourth driving member 113 drives the second coating component 130 to move along the first direction relative to the electrode plate.

[0056] More specifically, in the above-mentioned embodiment, the third driving member 112 and the fourth driving member 113 are both cylinders, which can achieve an adjustment accuracy of more than 0.1 mm.

[0057] Furthermore, in other embodiments, the third driving member 112 and the fourth driving member 113 may also be composed of a servo motor and a precision ball screw. The transmission is achieved by driving the precision ball screw with the servo motor, which can achieve an adjustment accuracy of more than 0.01 mm.

[0058] Further, in the above-mentioned embodiment, continue to refer to Figure 2 as well as Figure 4As shown, the driving component 110 includes a fifth driving member 114 and a sixth driving member 115. The first coating component 120 is drivingly connected to the fifth driving member 114. The fifth driving member 114 drives the first coating component 120 to move in the second direction relative to the electrode plate. The second coating component 130 is drivingly connected to the sixth driving member 115. The sixth driving member 115 drives the second coating component 130 to move in the second direction relative to the electrode plate.

[0059] Specifically, in the above-mentioned embodiment, the fifth driving member 114 and the sixth driving member 115 are both composed of a servo motor and a planetary reducer, which can accurately adjust the moving speed of the first coating component 120 and the second coating component 130 along the second direction to meet the requirements of different coating processes.

[0060] Furthermore, in other embodiments, the fifth driving member 114 and the sixth driving member 115 may also be other driving devices such as cylinders, DC motors, and stepper motors.

[0061] Specifically, the fifth driving member 114 drives the first coating assembly 120 to move at a maximum speed between 0.1 m / min and 1 m / min in the second direction, and the sixth driving member 115 drives the second coating assembly 130 to move at a maximum speed between 0.1 m / min and 1 m / min in the second direction.

[0062] It can be understood that since the driving component 110 can drive the first coating component 120 and the second coating component 130 to move along the first direction relative to the electrode plate, the driving component 110 can make the first coating component 120 and the second coating component 130 approach or move away from the electrode plate along the first direction, so as to adjust the distance between the third coating surface 121 and the first coating surface, and adjust the distance between the fourth coating surface 131 and the second coating surface, so as to adjust the coating thickness of the first coating surface and the coating thickness of the second coating surface, which can be adjusted according to the coating requirements of different electrode plates to improve the applicability of the above-mentioned coating equipment.

[0063] Specifically, in the above-mentioned embodiment, the coating thickness of the first coating surface and the second coating surface can be adjusted between 0.5 mm and 5 mm.

[0065] It can be understood that the first sliding member 122 can drive the second sliding member 123 and the first coating member 124 to move along the second direction by sliding the first sliding member 122 relative to the first connecting portion 141, thereby achieving coating of the first coating surface. Furthermore, the second sliding member 123 can drive the first coating member 124 to slide along the first direction by sliding the second sliding member 123 relative to the first sliding member 122, so as to adjust the distance between the third coating surface 121 and the first coating surface, thereby adjusting the coating thickness of the first coating surface, so as to achieve automated coating of the electrode plates, improve coating efficiency, and facilitate mass production of the electrode plates.

[0067] More specifically, in the above embodiment, in the second direction, the lengths of the third coating surface 121 and the fourth coating surface 131 are both between 5 mm and 50 mm.

[0068] Reference Figure 5 as well as Figure 6As shown, the first coating component 120 also includes a first feeding member 125 and a first guiding member 126. The output end of the feeding device 200 is connected to the input end of the first feeding member 125. One end of the first guiding member 126 is connected to the first coating member 124. The end of the first guiding member 126 away from the first coating member 124 is connected to the first feeding member 125. The first feeding member 125 is extended along a third direction. The first feeding member 125 is provided with a plurality of first feeding holes 1251 spaced apart along the third direction. The first guiding member 126 is provided with first blocking portions 1261 at both ends of the third direction. Each first blocking portion 1261 is extended along the second direction, and each first blocking portion 1261 is arranged between the first feeding member 125 and the first coating member 124. Any first feeding hole 1251 is located between the first blocking portions 1261 at both ends of the first guiding member 126. The third direction is perpendicular to the first direction and the second direction.

[0069] It should be noted that the third party Figure 2 The direction indicated by z is the length direction of the electrode plate.

[0070] Specifically, in the above-mentioned embodiment, each first material supply hole 1251 is connected to a nozzle to improve the uniformity of the material supply from the first material supplying member 125 to the first coating member 124 .

[0071] More specifically, in the above-mentioned embodiment, the nozzle connected to each first feeding hole 1251 is a duckbill nozzle, which can further improve the uniformity of the feeding of the first feeding member 125 to the first coating member 124 .

[0072] It can be understood that the material can be fed into the first feeding member 125 through the feeding device 200, and the material can be fed to the first coating member 124 through the first feeding member 125. In this process, since one end of the first guide member 126 is connected to the first coating member 124, the end of the first guide member 126 away from the first coating member 124 is connected to the first feeding member 125, and the first feeding member 125 is provided with a plurality of first feeding holes 1251 spaced apart along the third direction, the slurry can be fed through the plurality of first feeding holes 1251. The material flows out of the first material supply member 125 through the material hole 1251, and flows through the first material guide member 126, so as to be guided by the first material guide member 126, and finally flows to the first coating member 124 through the first material guide member 126, so as to realize the coating function of the first coating member 124, and the plurality of first material supply holes 1251 can ensure that the first coating member 124 is covered with the coating slurry at all places along the third direction, so as to improve the coating uniformity of the first coating member 124, further, improve the flatness of the coating surface of the first coating surface, and at the same time When the first guide member 126 is provided with first stoppers 1261 at both ends along the third direction, each first stopper 1261 is extended along the second direction, and each first stopper 1261 is arranged between the first feeding member 125 and the first coating member 124. Therefore, the first stoppers 1261 at both ends of the first guide member 126 can provide a certain flow guiding effect for the slurry, so as to ensure that the slurry on the first guide member 126 can flow to the first coating member 124, thereby avoiding the first guide member 125 from flowing to the first coating member 124. The slurry on 6 drips along the third direction to the outside of the first coating component 120, thereby reducing the slurry loss. Moreover, since any first feed hole 1251 is located between the first blocking parts 1261 at both ends of the first guide member 126, it is possible to prevent the slurry flowing out of each first feed hole 1251 from directly dripping from the first feed hole 1251 to the outside of the first coating component 120, so that the slurry flowing out of each first feed hole 1251 can flow to the first guide member 126, thereby further reducing the slurry loss.

[0073] Specifically, in the above-mentioned embodiments, referring to Figure 7 as well as Figure 8As shown, the second coating assembly 130 also includes a second feeding member 135 and a second guiding member 136. The output end of the feeding device 200 is connected to the input end of the second feeding member 135. One end of the second guiding member 136 is connected to the second coating member 134. The end of the second guiding member 136 away from the second coating member 134 is connected to the second feeding member 135. The second feeding member 135 is extended along a third direction. The second feeding member 135 is provided with a plurality of second feeding holes 1352 spaced apart along the third direction. The second guiding member 136 is provided with second stopping portions 1361 at both ends along the third direction. Each second stopping portion 1361 is extended along the second direction, and each second stopping portion 1361 is arranged between the second feeding member 135 and the second coating member 134. Any second feeding hole 1352 is located between the second stopping portions 1361 at both ends of the second guiding member 136.

[0074] Furthermore, in the above-mentioned embodiment, each second material supply hole 1352 is connected to a nozzle to improve the uniformity of the material supply from the second material supply member 135 to the second coating member 134 .

[0075] More specifically, in the above-mentioned embodiment, the nozzle connected to each second feeding hole 1352 is a duckbill nozzle, which can further improve the uniformity of the feeding of the second feeding member 135 to the second coating member 134 .

[0076] Reference Figure 5 as well as Figure 6 As shown, the first guide member 126 also has a first guide portion 1262 and a second guide portion 1263, the second guide portion 1263 is connected to the first coating member 124, one end of the first guide portion 1262 is connected to the first feeding member 125, and the other end of the first guide portion 1262 is connected to the second guide portion 1263, in the first direction, the third coating surface 121 is located on the side of the second guide portion 1263 away from the first guide portion 1262, and any first feeding hole 1251 is located on the side of the first guide portion 1262 away from the second guide portion 1263, in the third direction, both ends of the first guide portion 1262 and both ends of the second guide portion 1263 are provided with a first blocking portion 1261; wherein, the first guide portion 1262 and the second guide portion 1263 are arranged at an angle, and the angle between the first guide portion 1262 and the second guide portion 1263 can be adjusted under the action of external force.

[0077] Specifically, in the above-mentioned embodiment, at the same end of the first material guide portion 1262 and the second material guide portion 1263 along the third direction, there is a certain gap between the first material stop portion 1261 arranged on the first material guide portion 1262 and the first material stop portion 1261 arranged on the second material guide portion 1263. When the angle between the first material guide portion 1262 and the second material guide portion 1263 is adjusted, interference between the first material stop portion 1261 arranged on the first material guide portion 1262 and the first material stop portion 1261 arranged on the second material guide portion 1263 can be avoided.

[0078] It can be understood that, in the first direction, the third coating surface 121 is located on the side of the second material guide portion 1263 away from the first material guide portion 1262, and any first material supply hole 1251 is located on the side of the first material guide portion 1262 away from the second material guide portion 1263. Fig. 9 As shown, after the slurry flows out of the first feeding member 125 through the first feeding hole 1251, it can flow through the first guiding portion 1262, the second guiding portion 1263 and the first coating surface in sequence. Since the first guiding portion 1262 and the second guiding portion 1263 are arranged at an angle, a first guiding space 1264 can be defined between the first guiding portion 1262 and the second guiding portion 1263 to slow down the flow speed of the slurry on the first guiding member 126, so that part of the slurry can be stored in the first guiding space 1264, thereby ensuring that the third coating surface 121 has sufficient slurry, improving the coating quality, and preventing the slurry from dripping due to excessive flow rate. At the same time, in the third direction, First material blocking portions 1261 are provided at both ends of the first material guide portion 1262 and both ends of the second material guide portion 1263. Therefore, when the slurry is stored in the first material guide space 1264, the first material blocking portion 1261 can prevent the slurry from flowing out of the first material guide hole space along the third direction, thereby reducing the slurry loss. Furthermore, since the angle between the first material guide portion 1262 and the second material guide portion 1263 is adjustable, the angle between the first material guide portion 1262 and the second material guide portion 1263 can be adjusted according to the angle of the first coating surface, thereby adjusting the angle of the third coating surface 121 so that the third coating surface 121 can be parallel to the first coating surface.

[0079] Specifically, refer to Figure 7 as well as Figure 8As shown, the second guide member 136 also has a third guide portion 1362 and a fourth guide portion 1363, the fourth guide portion 1363 is connected to the second coating member 134, one end of the third guide portion 1362 is connected to the second feeding member 135, and the other end of the third guide portion 1362 is connected to the fourth guide portion 1363. In the first direction, the fourth coating surface 131 is located on the side of the fourth guide portion 1363 away from the third guide portion 1362, and any second feeding hole 1352 are both located on the side of the third material guide portion 1362 away from the fourth material guide portion 1363, and in the third direction, both ends of the third material guide portion 1362 and both ends of the fourth material guide portion 1363 are provided with second material blocking portions 1361; wherein, the third material guide portion 1362 and the fourth material guide portion 1363 are arranged at an angle to define a second material guide space 1364, and the angle between the third material guide portion 1362 and the fourth material guide portion 1363 can be adjusted under the action of external force.

[0080] Specifically, in the above-mentioned embodiment, at the same end of the third guide portion 1362 and the fourth guide portion 1363 along the third direction, there is a certain gap between the second material stopping portion 1361 arranged on the third guide portion 1362 and the second material stopping portion 1361 arranged on the fourth guide portion 1363, so that when the angle between the third guide portion 1362 and the fourth guide portion 1363 is adjusted, interference between the second material stopping portion 1361 arranged on the third guide portion 1362 and the second material stopping portion 1361 arranged on the fourth guide portion 1363 can be avoided.

Since the second guide portion 1263 is fixedly connected to the first coating member 124, when the first coating member 124 rotates about the third direction, the second guide portion 1263 can be driven to rotate about the third direction through the first coating member 124, so as to adjust the angle between the second guide portion 1263 and the first guide portion 1262, and adjust the angle of the third coating surface 121 so that the third coating surface 121 can be parallel to the first coating surface.
