Detailed Implementation

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0039] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0040] like Figure 1 and Figure 2 As shown, the oiling equipment 100 of this application embodiment includes a conveying device 110 and a brushing device 120, an oiling device 130, a cleaning device 140, and a drying device 150 arranged sequentially along the conveying direction of the conveying device 110. The conveying device 110 is used to convey battery cells 200, the brushing device 120 is used to brush the battery cells 200 with a first cleaning liquid, the oiling device 130 is used to spray rust-preventive oil onto the battery cells 200, the cleaning device 140 is used to spray a second cleaning liquid onto the battery cells 200, and the drying device 150 is used to blow air onto the battery cells 200. Among them, the brushing device 120 includes a first brushing mechanism 121, which includes two side brush assemblies 1211 and a first spray assembly 1212. The two side brush assemblies 1211 are arranged at intervals. The first spray assembly 1212 is used to spray the first cleaning liquid onto one of the side brush assemblies 1211. The side brush assembly 1211 is used to brush the outer peripheral surface 210 of the battery cell 200.

[0041] like Figure 17 As shown, the conveying device 110 conveys the battery cell 200 along the first direction X, and the battery cell 200 remains vertical during the conveying process. The battery cell 200 is a cylindrical battery with its axis extending along the vertical direction Z. The outer peripheral surface 210 of the battery cell 200 refers to the cylindrical surface of the battery cell 200, that is, the side surface extending around its axis; the top surface 220 of the battery cell 200 refers to its upper side surface along the vertical direction Z, and the bottom surface 230 of the battery cell 200 refers to its lower side surface along the vertical direction Z. The first cleaning fluid is ordinary circulating water, and the second cleaning fluid is purified water; in other embodiments, the first and second cleaning fluids may also be other types of cleaning fluids.

[0042] The oiling device 100 of this application embodiment includes a first brushing mechanism 121. The first brushing mechanism 1211 includes two side brush assemblies 1211 and a first spray assembly 1212. The first spray assembly 1212 sprays a first cleaning liquid onto one of the side brush assemblies 1211 to improve the brushing effect on the outer peripheral surface 210 of the battery cell 200. The other side brush assembly 1211 brushes the outer peripheral surface 210 of the battery cell 200 from the other side to completely remove residual electrolyte, reduce the impact of insufficient brushing on the oiling effect, and thus improve the uniformity and comprehensiveness of oiling.

[0043] like Figure 2 and Figure 5 As shown, the two side brush assemblies 1211 are a first side brush assembly 1211a and a second side brush assembly 1211b, respectively. The first side brush assembly 1211a and the second side brush assembly 1211b are spaced apart along the second direction Y on both sides of the conveying device 110 to brush the outer peripheral surface 210 of the battery cell 200 from both sides. The first spray assembly 1212 is disposed along the second direction Y on the outside of the first side brush assembly 1211a, that is, on the side of the first side brush assembly 1211a away from the second side brush assembly 1211b.

[0044] like Figure 1 and Figure 5 As shown, in some embodiments of this application, the side brush assembly 1211 includes a plurality of spaced-apart column brushes 1213, and the first brushing mechanism 121 further includes a first lifting assembly 1214 and a first driving assembly 1215. The first lifting assembly 1214 is used to drive the two side brush assemblies 1211 to descend to a first brushing height position, and the first spray assembly 1212 is configured to spray a first cleaning liquid onto the side brush assembly 1211 located at the first brushing height position; the first driving assembly 1215 is disposed at the execution end of the first lifting assembly 1214 and is used to drive the plurality of column brushes 1213 to rotate around their own axis.

[0045] The side brush assembly 1211 includes a plurality of column brushes 1213 spaced apart along the first direction X. The rotation axis of the column brushes 1213 is parallel to the vertical direction Z. The brushing device 120 also includes a frame 125. A first lifting assembly 1214 is mounted on the frame 125. The execution end of the first lifting assembly 1214 is provided with a first lifting plate 1216. A first drive assembly 1215 and two side brush assemblies 1211 are all mounted on the first lifting plate 1216. The first lifting assembly 1214 drives the first lifting plate 1216 to move along the vertical direction Z, so as to drive the first drive assembly 1215 and the two side brush assemblies 1211 to rise and fall synchronously. The first drive assembly 1215 drives the plurality of column brushes 1213 of the side brush assembly 1211 to rotate synchronously.

[0046] The first spray assembly 1212 is mounted on the frame of the conveying device 110 via a first spray bracket 1217. The first spray assembly 1212 includes a plurality of first spray heads 1218 spaced apart along a first direction X. Each first spray head 1218 corresponds to a column brush 1213 of the first side brush assembly 1211a. The plurality of first spray heads 1218 are positioned at a first brushing height position. The first lifting assembly 1214 drives the side brush assembly 1211a to descend along the vertical direction Z to the first brushing height position. Each first spray head 1218 is used to spray a first cleaning liquid onto the corresponding column brush 1213.

[0047] The first lifting assembly 1214 is a common motor lead screw and nut mechanism, and the first drive assembly 1215 is a common motor synchronous belt mechanism. There are two first drive assemblies 1215, and each first drive assembly 1215 drives the multiple column brushes 1213 of the corresponding side brush assembly 1211 to rotate.

[0048] With this configuration, the side brush assembly 1211 can be lowered to the first brushing height position simply and reliably, and the height position of the first spray assembly 1212 is fixed, which facilitates connection with an external pumping device.

[0049] In other embodiments, the first spray assembly 1212 may also be installed on the first lifting plate 1216; or, the side brush assembly 1211 may also be used to brush the outer peripheral surface 210 of the battery cell 200 by means of the brush belt reciprocating along the first direction X.

[0050] like Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments of this application, the brushing device 120 further includes a second brushing mechanism 122. The first brushing mechanism 121 and the second brushing mechanism 122 are arranged at intervals along the conveying direction of the conveying device 110. The second brushing mechanism 122 includes a top brush assembly 123, a bottom brush assembly 124, a second spray assembly 1221, and a third spray assembly 1222. The top brush assembly 123 is disposed above the bottom brush assembly 124. The top brush assembly 123 is used to brush the top surface 220 of the battery cell 200, and the bottom brush assembly 124 is used to brush the bottom surface 230 of the battery cell 200. The second spray assembly 1221 is used to spray the first cleaning liquid onto the top brush assembly 123, and the third spray assembly 1222 is used to spray the first cleaning liquid onto the bottom brush assembly 124.

[0051] The second scrubbing mechanism 122 is disposed downstream of the first scrubbing mechanism 121 along the first direction X, the top brush assembly 123 is disposed above the bottom brush assembly 124 along the vertical direction Z, the second spray assembly 1221 includes a plurality of second spray heads 1225 disposed along the first direction X, and the third spray assembly 1222 includes a plurality of third spray heads 1226 disposed at intervals along the first direction X.

[0052] With this configuration, the top brush assembly 123 and the bottom brush assembly 124 can be sprayed with the first cleaning liquid to clean the top surface 220 and bottom surface 230 of the battery cell 200. The outer peripheral surface 210 of the battery cell 200 is first cleaned by the first cleaning mechanism 121, and then the end surface of the battery cell 200 is cleaned by the second cleaning mechanism 122. This configuration not only provides sufficient space for the side brush assembly 1211, the top brush assembly 123 and the bottom brush assembly 124 to be equipped with corresponding spraying components, thereby improving the cleaning effect, but also reduces the travel resistance of the battery cell 200, thereby reducing the load on the conveying device 110 while ensuring the cleaning effect.

[0053] In other embodiments, the first brushing mechanism 121 and the second brushing mechanism 122 may also be integrated in the same work station. For example, the bottom brush assembly 124 is disposed on the lower side of the side brush assembly 1211, and the top brush assembly 123 and the side brush assembly 1211 are both installed on the first lifting plate 1216.

[0054] like Figure 1 , Figure 3 and Figure 6 As shown, in some embodiments of this application, the top brush assembly 123 includes a plurality of spaced-apart top brush members 1231, and the second brushing mechanism 122 further includes a second lifting assembly 1223 and a second driving assembly 1224. The second lifting assembly 1223 is used to drive the top brush assembly 123 to descend to a second brushing height position, and the second spray assembly 1221 is configured to spray a first cleaning liquid onto the top brush assembly 123 located at the second brushing height position; the second driving assembly 1224 is disposed at the execution end of the second lifting assembly 1223 and is used to drive the plurality of top brush members 1231 to rotate around their own axis.

[0055] Multiple top brush components 1231 are spaced apart along the first direction X, and the rotation axis of the top brush components 1231 is parallel to the vertical direction Z. A second lifting assembly 1223 is mounted on the frame 125. The actuating end of the second lifting assembly 1223 is provided with a second lifting plate 1227. The second drive assembly 1224 and the top brush components 123 are both mounted on the second lifting plate 1227. The second lifting assembly 1223 drives the second lifting plate 1227 to move along the vertical direction Z, so as to drive the second drive assembly 1224 and the top brush components 123 to lift and lower synchronously. The second drive assembly 1224 drives the multiple top brush components 1231 to rotate synchronously.

[0056] The top brush component 1231 corresponds one-to-one with the second spray head 1225. The second spray assembly 1221 is mounted on the frame of the conveying device 110 via the second spray bracket 1228. Multiple second spray heads 1225 are set at the second brushing height position. The second lifting assembly 1223 drives the top brush assembly 123 to descend vertically in the Z direction to the second brushing height position. Each second spray head 1225 is used to spray the first cleaning liquid onto the corresponding top brush component 1231.

[0057] The second lifting component 1223 is a common motor lead screw and nut mechanism, and the second drive component 1224 is a common motor synchronous belt mechanism, which will not be described in detail here.

[0058] With this configuration, the top brush assembly 123 can be lowered to the second brushing height position simply and reliably, and the height position of the second spray assembly 1221 is fixed, which facilitates connection with an external pumping device.

[0059] In other embodiments, the second spray assembly 1221 may also be installed on the second lifting plate 1227.

[0060] like Figure 7 As shown, in some embodiments of this application, the bottom brush assembly 124 includes a third drive assembly 1241, a timing belt 1242, and a brush bar 1243. The brush bar 1243 is configured as a segment of the timing belt 1242. The third drive assembly 1241 is used to drive the timing belt 1242 to reciprocate, thereby driving the brush bar 1243 to reciprocate. The brush bar 1243 is used to brush the bottom surface 230 of the battery cell 200. The third spray assembly 1222 is used to spray a first cleaning liquid onto the brush bar 1243.

[0061] The brush bar 1243 has a brush structure on its upper side and can be attached to the upper side of the timing belt 1242. Both ends of the brush bar 1243 can also be connected to the timing belt 1242, forming a complete annular transmission belt. The timing belt 1242 reciprocates along the first direction X, driving the brush bar 1243 to reciprocate along the first direction X, thus brushing the bottom surface 230 of the battery cell 200. Multiple third spray heads 1226 of the third spray assembly 1222 spray a first cleaning solution onto the brush bar 1243.

[0062] With this configuration, the brush strip 1243 can thoroughly clean the bottom surface 230 of the battery cell 200, and the brush strip 1243 can catch the dripping first cleaning liquid, which not only improves the cleaning effect, but also reduces the phenomenon of waste liquid splashing from the second cleaning mechanism 122.

[0063] In other embodiments, the bottom brush assembly 124 may also employ multiple rotating brush heads, with each rotating brush head corresponding to a top brush 1231.

[0064] In some embodiments of this application, the second brushing mechanism 122 further includes a bottom brush mounting plate 1229, and the bottom brush assembly 124 and the third spray assembly 1222 are both disposed on the bottom brush mounting plate 1229.

[0065] With this configuration, the relative positions of the third spray assembly 1222 and the bottom brush assembly 124 remain unchanged, ensuring the spraying effect on the brush strip 1243, and thus ensuring the brushing effect on the bottom surface 230 of the battery cell 200.

[0066] In other embodiments, the bottom brush assembly 124 can also be vertically and vertically mounted on the frame 125 in the Z direction, and the corresponding lifting drive assembly drives the bottom brush assembly 124 to adjust to a preset brushing height position, and the third spray assembly 1222 is fixedly set at the preset brushing height position.

[0067] It is understood that the first brushing mechanism 121 in this embodiment of the application is provided with a first spray assembly 1212, the second brushing mechanism 122 is provided with a second spray assembly 1221 and a third spray assembly 1222, and the side brush assembly 1211, the top brush assembly 123 and the bottom brush assembly 124 are respectively provided with corresponding spray assemblies. High-quality brushing operations can be performed on the outer peripheral surface 210, top surface 220 and bottom surface 230 of the battery cell 200, which improves the overall brushing effect and can improve the uniformity and comprehensiveness of oiling.

[0068] like Figure 8 , Figure 9 and Figure 10 As shown, in some embodiments of this application, the oiling device 130 includes a plurality of oiling spray assemblies 131 arranged at intervals. Each oiling spray assembly 131 includes two side oiling spray sections 1311, a top oiling spray section 1312, and a bottom oiling spray section 1313 arranged opposite to each other. The bottom oiling spray section 1313 is disposed below the top oiling spray section 1312.

[0069] The side oil spraying section 1311 is used to spray anti-rust oil onto the outer peripheral surface 210 of the battery cell 200, the top oil spraying section 1312 is used to spray anti-rust oil onto the top surface 220 of the battery cell 200, and the bottom oil spraying section 1313 is used to spray anti-rust oil onto the bottom surface 230 of the battery cell 200.

[0070] The oiling device 130 also includes an oiling bracket 132, a plurality of oiling spraying components 131 are spaced apart along the first direction X on the oiling bracket 132, two side oiling spraying parts 1311 are spaced apart along the second direction Y on both sides of the conveying device 110, respectively spraying anti-rust oil from both sides of the battery cell 200 along the second direction Y; the top oiling spraying part 1312 and the bottom oiling spraying part 1313 are arranged opposite each other along the vertical direction Z, respectively spraying anti-rust oil from the top and bottom sides of the battery cell 200.

[0071] The side oiling spray section 1311 includes three spray heads 1314 spaced apart along the first direction X. The top oiling spray section 1312 and the bottom oiling spray section 1313 both include three spray heads 1314 spaced apart along the first direction X.

[0072] With this configuration, rust-preventive oil can be sprayed onto the battery cell 200 from different angles, ensuring that the outer peripheral surface 210, top surface 220 and bottom surface 230 of the battery cell 200 are all coated with rust-preventive oil, forming a passivation protective film.

[0073] like Figure 11 As shown, in some embodiments of this application, the cleaning device 140 includes a plurality of cleaning spray assemblies 141 arranged at intervals. The cleaning spray assembly 141 includes two side cleaning spray sections 1411, a top cleaning spray section 1412 and a bottom cleaning spray section 1413 arranged opposite to each other. The bottom cleaning spray section 1413 is disposed below the top cleaning spray section 1412 and is used to spray a second cleaning liquid onto the bottom surface 230 of the battery cell 200.

[0074] The side cleaning spray section 1411 sprays a second cleaning liquid onto the outer peripheral surface 210 of the battery cell 200, the top cleaning spray section 1412 sprays a second cleaning liquid onto the top surface 220 of the battery cell 200, and the bottom cleaning spray section 1413 sprays a second cleaning liquid onto the bottom surface 230 of the battery cell 200. The structure of the cleaning device 140 is the same as that of the oiling device 130, and will not be described further here.

[0075] With this configuration, the second cleaning fluid can be sprayed onto the battery cell 200 from different angles, ensuring that the outer peripheral surface 210, top surface 220 and bottom surface 230 of the battery cell 200 can be thoroughly cleaned.

[0076] It is understood that the aforementioned scrubbing device 120, oiling device 130 and cleaning device 140 all include corresponding liquid supply devices, which will not be described in detail here.

[0077] like Figure 12 , Figure 13 and Figure 14As shown, in some embodiments of this application, the air drying device 150 includes a first top air blowing section 151, two oppositely arranged side air blowing sections 153 and a bottom air blowing section 154, and the air outlet of the first top air blowing section 151 is an flared structure.

[0078] The air drying device 150 also includes an air drying bracket 155 and a second top air blowing section 152. The first top air blowing section 151, the second top air blowing section 152, two oppositely arranged side air blowing sections 153 and a bottom air blowing section 154 are all arranged on the air drying bracket 155. The first top air blowing section 151 and the second top air blowing section 152 are arranged on the upper side of the conveying device 110 and are used to blow the battery cells 200 from the top. The two side air blowing sections 153 are arranged on both sides of the conveying device 110 along the second direction Y, and their air outlets are arranged opposite each other along the second direction Y to blow the battery cells 200 from both sides. The bottom air blowing section 154 is arranged on the lower side of the conveying device 110 and is used to blow the battery cells 200 from the bottom.

[0079] The drying rack 155 comprises two side air blowing sections 153 and a first top air blowing section 151, forming an air blowing assembly 156. Multiple air blowing assemblies 156 are provided, spaced apart along a first direction X. The air outlets of the first top air blowing section 151 and the side air blowing sections 153 are flat-mouthed. The length direction of the air outlet of the first top air blowing section 151 extends along a second direction Y, and the length direction of the air outlet of the side air blowing section 153 extends along the first direction X. Multiple bottom air blowing sections 154 are provided, spaced apart along the first direction X, and the air outlets of the bottom air blowing sections 154 are upward-facing flared structures.

[0080] Multiple second top air blowing sections 152 are provided, and multiple second top air blowing sections 152 are spaced apart along the first direction X on the air drying bracket 155. The air outlet of the second top air blowing section 152 is a downward-facing flared structure.

[0081] The air drying device 150 is equipped with a corresponding air supply device to provide air with air pressure to each air blowing section.

[0082] With this configuration, air can be delivered to the surface of the battery cell 200 through the first top air blowing section 151 and the side air blowing section 153 of the flat-mouth structure, which can increase the wind speed and improve the blowing efficiency; combined with the bottom air blowing section 154 of the flared structure to deliver air to the surface of the battery cell 200, the blowing area can be increased and the blowing coverage can be improved.

[0083] In a preferred embodiment, the central axis of the air outlet of the bottom air blowing section 154 extends in the vertical direction Z. The bottom air blowing section 154 is provided with a rotation drive member, which is installed on the air drying bracket 155. The rotation drive member can drive the bottom air blowing section 154 to rotate around its own axis, further increasing the air supply area and forming multi-angle airflow to blow the battery cell 200 from different angles.

[0084] In a preferred embodiment, the second top blowing section 152 is disposed downstream of the plurality of blowing assemblies 156 along the conveying direction (i.e., the first direction X) of the conveying device 110, and the central axis of the air outlet of the second top blowing section 152 is parallel to the vertical direction Z. The second top blowing section 152 can rotate around its own axis to thoroughly blow the battery cell 200.

[0085] like Figure 15 As shown, in some embodiments of this application, the oiling device 100 further includes a drying device 160, which is disposed downstream of the air drying device 150, for drying the battery cells 200.

[0086] The conveying device 110 includes a drying conveying mechanism 114. The drying channel of the drying device 160 extends in a curved manner, and correspondingly, the conveying direction of the drying conveying mechanism 114 also extends in a curved manner. For example, the drying channel is a serpentine channel, and the drying conveying mechanism 114 extends in an S-shape. A magnetic attraction section is provided at the bend of the drying conveying mechanism 114 to magnetically attract the battery cells 200, reducing the possibility of material jamming at the bend.

[0087] By setting up the drying device 160, the second cleaning fluid remaining on the surface of the battery cell 200 can be dried by hot air.

[0088] like Figure 1 and Figure 15 As shown, in some embodiments of this application, the conveying device 110 includes a jig conveying mechanism 112 and a chain conveying mechanism 113. The jig conveying mechanism 112 is positioned corresponding to the brushing device 120. The chain conveying mechanism 113 is positioned downstream of the jig conveying mechanism 112. The chain conveying mechanism 113 is positioned corresponding to the oiling device 130, the cleaning device 140, and the drying device 150.

[0089] The conveying device 110 also includes a feeding mechanism 111 for receiving battery cells 200, and a fixture conveying mechanism 112 is located downstream of the feeding mechanism 111.

[0090] like Figure 1As shown, the fixture conveying mechanism 112 includes a fixture driving assembly 1121 and a plurality of fixtures spaced apart. The fixture driving assembly 1121 is used to drive the fixtures to move, and the fixtures are used to clamp the outer peripheral surface 210 of the battery cell 200. That is, during the process of the battery cell 200 passing through the first brushing mechanism 121 and the second brushing mechanism 122, it moves along the first direction X under the drive of the fixtures.

[0091] like Figure 1 As shown, the chain conveying mechanism 113 includes a chain drive assembly 1131 and a chain assembly 1132. The chain drive assembly 1131 drives the chain assembly 1132 to run, and the chain assembly 1132 carries and conveys the battery cells 200. That is, the battery cells 200 are placed on the chain assembly 1132 during the processes of the oiling device 130, cleaning device 140, and drying device 150, and move along the first direction X under the drive of the chain drive assembly 1131. The chain assembly 1132 includes two chains arranged side-by-side along the second direction Y. The battery cells 200 are placed on the two chains, and a gap forms a drainage groove between the two chains.

[0092] Specifically, there are three chain conveyor mechanisms 113, which are respectively installed in the oiling device 130, the cleaning device 140 and the drying device 150. Each chain conveyor mechanism 113 is set independently to facilitate the adjustment of the conveying speed and adapt to different rhythms.

[0093] This configuration overcomes the resistance caused by various brushing components during the brushing process, exposes the bottom surface 230 of the battery cell 200, effectively transports the battery cell 200 while allowing brushing of all surfaces of the battery cell 200; and allows waste liquid to be discharged in a timely manner during the subsequent oiling device 130, cleaning device 140 and drying device 150 processes, while leaving sufficient installation space on the upper side of the battery cell 200 to arrange the various devices.

[0094] In other embodiments, the conveying device 110 may also use a jig or chain to convey the battery cells 200.

[0095] like Figure 1 As shown, in some embodiments of this application, the workpiece fed into the conveying device 110 is an assembly of a battery cell 200 and a cup holder. The battery cell 200 is inserted into the cup holder. The fixture conveying mechanism 112 also includes a driven chain assembly 1122. During the process of the fixture driving the battery cell 200 forward, the driven chain assembly 1122 carries the cup holder and runs driven by it.

[0096] This configuration allows for the safe and reliable delivery of battery cells 200 with cup holders.

[0097] like Figure 16 As shown, in some embodiments of this application, the oiling device 130 further includes a lifting mechanism 133, which includes a push rod assembly 1331 and a positioning assembly 1332. The push rod assembly 1331 is configured to push the battery cell 200 upward, separating the battery cell 200 from the cup holder; the positioning assembly 1332 is disposed on the upper side of the push rod assembly 1331 and is configured to abut against the top surface 220 of the battery cell 200.

[0098] The lifting mechanism 133 is installed on the oiling bracket 132. The lifting rod assembly 1331 is located on the lower side of the battery cell 200. Multiple lifting rod assemblies 1331 are provided and are spaced apart along the first direction X. The positioning assembly 1332 is located on the upper side of the battery cell 200. Multiple positioning assemblies 1332 are provided and are spaced apart along the first direction X. The lifting rod assembly 1331, the positioning assembly 1332 and the battery cell 200 are arranged in a one-to-one correspondence. The push rod assembly 1331 includes a first cylinder 1333 and a push rod 1334. The first cylinder 1333 drives the push rod 1334 to push upward, lifting the battery cell 200 upward. The positioning assembly 1332 includes a second cylinder 1335 and a pressure rod 1336. The second cylinder 1335 drives the pressure rod 1336 to press downward. The end of the pressure rod 1336 is provided with a groove. The groove of the pressure rod 1336 locks the top of the battery cell 200. The push rod 1334 and the pressure rod 1336 together limit one battery cell 200 in the vertical direction Z.

[0099] like Figures 1 to 17 As shown, the working principle of the oiling device 100 in this embodiment is as follows:

[0100] Battery cell 200 is fed to feeding mechanism 111, and fixture conveying mechanism 112 receives and clamps battery cell 200 and conveys battery cell 200 along the first direction X.

[0101] The battery cell 200 passes through the first brushing mechanism 121, and the first spraying assembly 1212 sprays the first cleaning liquid onto the first side brush assembly 1211a. The first side brush assembly 1211a and the second side brush assembly 1211b jointly brush the outer peripheral surface 210 of the battery cell 200 from both sides in the second direction Y.

[0102] The battery cell 200 passes through the second brushing mechanism 122. The second spray assembly 1221 sprays the first cleaning liquid onto the top brush assembly 123, and the third spray assembly 1222 sprays the first cleaning liquid onto the brush strip 1243 of the bottom brush assembly 124. Multiple top brushes 1231 and brush strips 1243 jointly brush the top surface 220 and bottom surface 230 of the battery cell 200.

[0103] The chain conveyor mechanism 113 receives and transports the battery cell 200. The battery cell 200 passes through the oiling device 130. The oiling spraying assembly 131 sprays anti-rust oil onto the battery cell 200 from the top, bottom, front, rear, left and right sides.

[0104] The battery cell 200 passes through the cleaning device 140, and the cleaning spray assembly 141 sprays a second cleaning liquid onto the battery cell 200 from the top, bottom, front, rear, left and right sides.

[0105] The battery cell 200 passes through the drying device 150, and the blowing assembly 156 blows air onto the battery cell 200 from the top, bottom, left and right sides. The first bottom blowing part 154 rotates around the vertical axis while blowing air, which can form a spiral wind and blow the battery cell 200 from multiple angles.

[0106] The battery cell 200 passes through the drying device 160 and is discharged after drying.

[0107] The oiling device 100 of this application embodiment has a brushing device 120 equipped with three spray components, which improve the brushing effect on the outer peripheral surface 210, top surface 220 and bottom surface 230 of the battery cell 200 respectively; the oiling device 130 includes a lifting mechanism 133, which can lift the battery cell 200 from the cup holder, improving the comprehensiveness of oiling; both the oiling device 130 and the cleaning device 140 adopt multi-directional spraying, spraying from various angles, improving the oiling effect and cleaning effect; the drying device 150 has a bottom blowing part 154 with a flared structure at the bottom, and the bottom blowing part 154 can rotate, improving the comprehensiveness of air blowing. The oiling device 100 of this application embodiment has made improvements in the brushing, oiling, cleaning and drying steps, which improves the overall oiling uniformity and comprehensiveness, and has a better oiling effect.

[0108] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0109] The above description is merely a preferred embodiment of this application and is not intended to limit this application.
