Technical Field

[0001] This invention relates to the field of battery manufacturing technology, and in particular to a turret-type cylindrical battery cell large-area dust removal device and its control method. Background Technology

[0002] The battery cell is the most important component of a battery. After undergoing a series of processes including mechanical / ultrasonic flattening, encapsulation, casing, current collector welding, and sealing welding, the battery cell can be assembled into a finished battery.

Detailed Implementation

[0040] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0041] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0042] The following is combined with Figures 1 to 6 This invention describes a turret-type cylindrical battery cell large-area dust removal device according to an embodiment of the present invention.

[0043] like Figure 1 , Figure 2 and Figure 3 As shown in the figure, the turret-type cylindrical battery cell large-area dust removal equipment provided in this embodiment of the invention includes: a dust removal device 1, a first detection device 2, and a rejection device.

[0044] The dust removal device 1 includes a first turret mechanism 11, a plurality of first clamping mechanisms 12, and a dust removal mechanism 13. Each first clamping mechanism 12 is arranged sequentially at intervals along the circumference of the first turret mechanism 11, and the two ends of the first clamping mechanism 12 are used to abut against the two opposite ends of the battery cell, respectively. The dust removal mechanism 13 is located on one side of the first turret mechanism 11 and is used to remove dust from the circumferential surface of the battery cell held by the first clamping mechanism 12. The first detection device 2 is arranged at intervals with the dust removal device 1 and is used to detect the cleanliness of the battery cell after dust removal. The rejection device is used to reject defective battery cells before and / or after dust removal.

[0045] Specifically, both the dust removal device 1 and the first detection device 2 can be rotary disc structures. The dust removal device 1 is used to remove dust from the circumferential surface of the battery cell to ensure that the cleanliness of the battery cell surface meets the requirements before it is installed in the casing. The battery cell after being dusted by the dust removal device 1 is transferred to the first detection device 2, which is used to detect the cleanliness of the dust-removed battery cell.

[0046] The rejection device is used to reject defective battery cells before or after dust removal, ensuring production line efficiency. For example, the rejection device includes a first rejection mechanism 31 and a second rejection mechanism 32. The first rejection mechanism 31 is located on the inlet side of the dust removal device 1 and is used to reject first-batch defective battery cells whose height does not meet the requirements for dust removal when they are conveyed to the dust removal device 1. First-batch good-quality battery cells that meet the height requirements enter the dust removal device 1. The second rejection mechanism 32 is located on one side of the first detection device 2 and is used to reject second-batch defective battery cells whose cleanliness does not meet the requirements after dust removal.

[0047] like Figure 2 As shown, in an optional embodiment, the first turret mechanism 11 includes a rotating body 111, a support member 112, and an annular track 113. The support member 112 is disposed around the rotating body 111 and includes a mounting plate 1121 and a bearing plate 1122. The mounting plate 1121 is connected to the rotating body 111, and the bearing plate 1122 is vertically disposed on the mounting plate 1121 for supporting the battery cell. The annular track 113 is coaxially disposed with the rotating body 111 and is opposite to the bottom of the support member 112.

[0048] The first clamping mechanism 12 includes a lifting component 121 and a pressing component 122. The lifting component 121 is movably mounted on the mounting plate 1121 in the vertical direction, and the bottom of the lifting component 121 abuts against the annular track 113. The pressing component 122 is disposed opposite to the lifting component 121. The lifting component 121 and the pressing component 122 are used to abut against the two ends opposite to the battery cell. The dust removal mechanism 13 is disposed on one side of the first clamping mechanism 12 and is used to remove dust from the circumferential surface of the battery cell.

[0049] like Figure 2As shown, the first turret mechanism 11 includes a rotating body 111, which includes a rotating shaft, a first support plate, and a second support plate. The first and second support plates are sleeved on the rotating shaft and are spaced apart. The first turret mechanism 11 also includes a support member 112, which is located circumferentially around the rotating body 111. The support member 112 includes a mounting plate 1121 and a bearing plate 1122. The mounting plate 1121 is placed vertically, with one end connected to the first support plate and the other end connected to the second support plate. The bearing plate 1122 is vertically positioned above the mounting plate 1121 and is placed horizontally. The bearing plate 1122 is used to support the battery cells. It can be understood that the battery cells to be cleaned are placed in a tray, and the battery cells and the tray are placed together on the bearing plate 1122. The annular track 113 is coaxially arranged with the rotating body 111, and the annular track 113 is located at the bottom of the mounting plate 1121.

[0050] The first clamping mechanism 12 includes a lifting assembly 121 and a clamping assembly 122, both of which can be mounted on a mounting plate 1121. The lifting assembly 121 and the clamping assembly 122 are located on opposite sides of the support plate 1122. The lifting assembly 121 is movably mounted on the mounting plate 1121 in the vertical direction, and its bottom abuts against the annular track 113. The mounting plate 1121 is connected to a rotating body 111. During the rotation of the rotating body 111, the rotating body 111 drives the lifting assembly 121 and the clamping assembly 122 to rotate. The bottom of the lifting assembly 121 moves along the annular track 113, and the lifting assembly 121 can move vertically upward to lift the battery cell on the support plate 1122, so that the lifting assembly 121 abuts against the bottom surface of the battery cell, and the clamping assembly 122 abuts against the top surface of the battery cell. The further pressing component 122 can drive the battery cell to rotate, thereby completing the dust removal operation on the circumferential surface of the battery cell through the dust removal mechanism 13. Multiple first clamping mechanisms 12 can simultaneously clamp multiple battery cells to be dusted, and as the rotating body 111 rotates, the clamped multiple battery cells are dusted in sequence, resulting in high dust removal efficiency.

[0051] like Figure 3 As shown, a dust removal station is provided on one side of the first clamping mechanism 12, and a dust removal mechanism 13 is located at the dust removal station. The dust removal mechanism 13 includes a dust removal pipe 131. One end of the dust removal pipe 131 has an opening that faces the circumferential surface of the battery cell held by the first clamping mechanism 12. The opening is circular or elliptical in shape, and its size matches that of the battery cell. The other end of the dust removal pipe is connected to an adsorption unit or a blowing unit.

[0052] For example, the other end of the dust removal pipe 131 is connected to the adsorption unit, and the opening is the dust suction port. The dust suction port is opposite to the circumferential surface of the battery cell and is located close to the battery cell. The adsorption unit can provide negative pressure gas. When the battery cell to be dusted rotates to the dust removal station, it is clamped by the lifting component 121 and the pressing component 122. The driving component drives the battery cell to rotate around its own axis. The adsorption unit provides negative pressure gas, which adsorbs and removes dust from the circumferential surface of the battery cell through the dust removal pipe 131. The dust removal efficiency is high and the dust removal effect is excellent.

[0053] For example, the other end of the dust removal pipe 131 is connected to the blowing unit, and the opening is the air outlet. The air outlet is opposite to the circumferential surface of the battery cell and is set close to the battery cell. The blowing unit blows gas toward the circumferential surface of the battery cell through the dust removal pipe 131 to remove impurities adhering to the circumferential surface of the battery cell. After the battery cell to be dusted rotates to the dust removal station, it is clamped by the lifting component 121 and the pressing component 122. The driving component drives the battery cell to rotate around its own axis, and gas is blown toward the circumferential surface of the battery cell through the dust removal pipe 131. The dust removal efficiency is high and the dust removal effect is excellent.

[0054] After the dust removal operation is completed, the dust-removed battery cells are transferred to the first detection device 2 via a transfer turntable. The first detection device 2 has a similar structure to the dust removal device 1. The first detection device 2 includes a second turret mechanism, multiple second clamping mechanisms, and an image acquisition mechanism 21. The second turret mechanism has a similar structure to the first turret mechanism 11, and the second clamping mechanism has a similar structure to the first clamping mechanism 12. The specific structures of the second turret mechanism and the second clamping mechanism will not be described in detail.

[0055] After dust removal, the battery cells are transferred to the second turret mechanism, where a second clamping mechanism holds them. A detection station is located on one side of the second clamping mechanism, where an image acquisition mechanism 21 is positioned to acquire images of the dust-removed battery cells. Essentially, the image acquisition mechanism 21 acquires images of the circumferential surface of the dust-removed battery cells. Multiple second clamping mechanisms 12 can simultaneously hold multiple dust-removed battery cells. As the second turret mechanism rotates, the dust removal quality of the clamped battery cells is sequentially detected, resulting in high detection efficiency.

[0056] like Figure 6As shown, the second rejection mechanism 32 is located near the first detection device 2. The second turret mechanism has a sorting turntable 6, a first unloading turntable, and a second unloading turntable arranged circumferentially. The battery cells held by the second clamping mechanism are transferred to the sorting turntable 6 as the second turret mechanism rotates. The second rejection mechanism 32 includes a movable paddle 321 and a drive push rod 322. The movable paddle 321 is mounted on the end face of the sorting turntable 6. The drive push rod 322 has a reciprocating stroke towards the corresponding unloading station and is used to drive the movable paddle 321. The drive push rod 322 pushes the second good-quality battery cells that meet the cleanliness requirements into the first unloading turntable via the movable paddle 321, and further transfers them to the good-quality output chain plate 7 via the rotation of the first unloading turntable. The drive push rod 322 also pushes the second defective battery cells that do not meet the cleanliness requirements into the second unloading turntable via the movable paddle 321, and further transfers them to the defective output chain plate 8 via the rotation of the second unloading turntable.

[0057] In this embodiment of the invention, a plurality of first clamping mechanisms 12 are arranged sequentially at intervals along the circumference of the first turret mechanism 11. The first clamping mechanisms 12 are used to clamp the opposite ends of the battery cells. The plurality of first clamping mechanisms 12 can clamp a plurality of battery cells at the same time. The dust removal mechanism 13 removes dust from the circumferential surface of the battery cells. The dust removal equipment occupies a small space, has high dust removal efficiency, and has a good dust removal effect. At the same time, by setting a first detection device 2 and a rejection device, defective battery cells are rejected before and after dust removal, which helps to improve the working efficiency of the production line.

[0058] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in an optional embodiment, the lifting assembly 121 includes a lifting rod 1212, a top plate 1211, and a roller 1213. One end of the top plate 1211 is connected to the lifting rod 1212, and the other end is connected to the roller 1213. The roller 1213 can roll along the annular track 113 to make the top plate 1211 move in the vertical direction. The top plate 1211 drives the lifting rod 1212 to lift the battery cell. The lifting rod 1212 is used to abut against one end of the battery cell.

[0059] The clamping assembly 122 includes a mounting bracket 1221, a pressure head 1222, and a driving member 1223. The mounting bracket 1221 is disposed on the mounting plate 1121, the pressure head 1222 is disposed on the mounting bracket 1221, and the driving end of the driving member 1223 is connected to the pressure head 1222. The pressure head 1222 is used to abut against the other end of the battery cell.

[0060] Specifically, the lifting assembly 121 includes a lifting rod 1212, a top plate 1211, and rollers 1213. The top plate 1211 is vertically oriented, and a connecting plate is provided on the top of the top plate 1211. The connecting plate is horizontally placed, and the bottom of the lifting rod 1212 is connected to the connecting plate. The rollers 1213 are installed on the bottom of the top plate 1211, rotatably connected to the top plate 1211, and rollingly contacting the annular track 113. The top of the lifting rod 1212 is also provided with a driven wheel, which is rotatably connected to the lifting rod 1212 and can rotate around the axis of the lifting rod 1212. It can be understood that the support plate 1122 has a first through hole, and the bottom of the cup has a second through hole. The lifting rod 1212 can pass through the first through hole and the second through hole in sequence, moving vertically upward to lift the battery cell placed in the cup.

[0061] The clamping assembly 122 includes a mounting bracket 1221, a pressure head 1222, and a drive component 1223. The mounting bracket 1221 is located on top of the mounting plate 1121, and the drive component 1223 is fixed to the mounting bracket 1221. The drive component 1223 can be a motor, and the drive shaft of the motor is connected to the pressure head 1222. The motor can drive the pressure head 1222 to rotate around its own axis. The central axis of the pressure head 1222 is consistent with the central axis of the push rod 1212.

[0062] The lifting assembly 121 and the clamping assembly 122 rotate with the first turret mechanism 11. The roller 1213 moves along the annular track 113. When the roller 1213 reaches the high position of the annular track 113, the top plate 1211 drives the top rod 1212 to move vertically upward. The top rod 1212 passes through the first and second through holes and gradually lifts the battery cell in the cup until the top surface of the driven wheel abuts against the bottom surface of the battery cell. The pressure head 1222 abuts against the top surface of the battery cell, clamping the battery cell by the top rod 1212 and the pressure head 1222. Then, the driving component 1223 drives the pressure head 1222 to rotate, and the dust removal pipe 131 of the dust removal mechanism 13 adsorbs impurities on the circumferential surface of the battery cell. After the dust removal operation is completed, the roller 1213 continues to move along the circular track 113. When the roller 1213 reaches the lower position of the circular track 113, the top plate 1211 drives the top rod 1212 to move vertically downwards. The pressure head 1222 gradually separates from the top surface of the battery cell, and the top rod 1212 gradually separates from the bottom surface of the battery cell, until the pressure head 1222 and the top rod 1212 are completely separated from the battery cell. The dust-removed battery cell can then be transferred to the first testing device 2 to test the cleanliness of the battery cell after dust removal.

[0063] In this embodiment of the invention, the roller 1213 moves along the annular track 113, so that the top plate 1211 can move in the vertical direction. The top plate 1211 drives the top rod 1212 to move in the vertical direction to lift the battery cell. The overall structure is compact and can easily achieve the clamping and releasing of the battery cell.

[0064] like Figure 2 As shown, in an optional embodiment, the annular track 113 is constructed with an arc-shaped track, and the roller 1213 moves along the arc-shaped track, which can drive the top plate 1211 to move in the vertical direction.

[0065] Specifically, the circular track 113 is composed of an arc-shaped track and a straight track connected end to end. The arc-shaped track corresponds to the dust removal station and consists of an ascending arc segment and a descending arc segment. The roller 1213 can roll along the trajectory line of the circular track 113.

[0066] The first turret mechanism 11 drives the first clamping mechanism 12 to rotate to the arc-shaped track. Under the drive of the first turret mechanism 11, the roller 1213 first rolls along the rising arc segment so that the top plate 1211 moves upward in the vertical direction until the roller 1213 rolls to the highest point of the rising arc segment. At this time, the top surface of the driven wheel abuts against the bottom surface of the battery cell, and the pressure head 1222 abuts against the top surface of the battery cell. The pressure head 1222 and the driven wheel press against the opposite ends of the battery cell.

[0067] After the pressure head 1222 and the driven wheel press against the battery cell, the first turret mechanism 11 stops rotating. Then, the driving component 1223 drives the pressure head 1222 to rotate. The pressure head 1222 and the driven wheel drive the battery cell to rotate around its own axis, and the dust removal mechanism 13 performs dust removal on the battery cell. After the dust removal is completed, under the drive of the first turret mechanism 11, the roller 1213 continues to roll along the descending arc, so that the top plate 1211 moves vertically downwards until the roller 1213 rolls to the lowest point of the descending arc. The driven wheel and the pressure head 1222 separate from the battery cell, and then the dust-removed battery cell can be transferred to the first detection device 2.

[0068] In this embodiment of the invention, the first turret mechanism 11 drives the roller 1213 to roll along the arc-shaped track. The roller 1213 drives the top rod 1212 to move upward or downward in the vertical direction through the top plate 1211. The lifting assembly 121 does not require a driving source, has a simple structure, and is reliable in operation.

[0069] like Figure 3 and Figure 5 As shown, in an optional embodiment, the lifting assembly 121 further includes a first elastic assembly 1214; the first elastic assembly 1214 includes a first fixed block 12141, a first movable block 12142 and a first elastic member 12143, the first movable block 12142 is disposed on the top plate 1211, the first fixed block 12141 is disposed on the mounting plate 1121, one end of the first elastic member 12143 is connected to the first fixed block 12141, and the other end of the first elastic member 12143 is connected to the first movable block 12142.

[0070] Specifically, the first movable block 12142 and the first fixed block 12141 are arranged parallel to each other at intervals along the height direction, and the top plate 1211 and the mounting plate 1121 are arranged parallel to each other at intervals. The first movable block 12142 is installed at the bottom of the top plate 1211 and can be fixed to the top plate 1211 by welding or screwing. The first movable block 12142 can move synchronously with the top plate 1211. The first fixed block 12141 is installed on the mounting plate 1121 and can be fixed to the mounting plate 1121 by welding or screwing. It can be understood that the first fixed block 12141 is located below the bearing plate 1122.

[0071] The first elastic element 12143 can be a cylindrical spring. One end of the first elastic element 12143 is connected to the first fixed block 12141, and the other end of the first elastic element 12143 is connected to the first movable block 12142. When the top plate 1211 moves upward in the vertical direction, the top plate 1211 drives the first movable block 12142 to move upward, and the first elastic element 12143 is compressed. When the top plate 1211 moves downward in the vertical direction, the top plate 1211 drives the first movable block 12142 to move downward, and the first elastic element 12143 gradually returns to its initial state.

[0072] In this embodiment of the invention, the first elastic element 12143 can provide the lifting assembly 121 with a certain floating space, which is conducive to the smooth rise and fall of the top plate 1211, and thus conducive to the smooth rise and fall of the top rod 1212.

[0073] like Figure 3 As shown, in an optional embodiment, the first elastic component 1214 further includes a guide block 12144, which is disposed on the mounting plate 1121 and located between the first fixed block 12141 and the first movable block 12142. The first elastic member 12143 passes through the guide block 12144.

[0074] Specifically, the guide block 12144 is located between the first movable block 12142 and the first fixed block 12141. The guide block 12144 can be fixed to the mounting plate 1121 by welding or screwing. The guide block 12144 is provided with a guide hole, the diameter of which is adapted to the diameter of the first elastic element 12143.

[0075] After the first elastic element 12143 passes through the guide hole of the guide block 12144, its two ends are connected to the first fixed block 12141 and the first movable block 12142, respectively. The reciprocating motion of the top plate 1211 in the vertical direction causes the first elastic element 12143 to be repeatedly compressed and rebounded in the vertical direction. The guide block 12144 ensures that the first elastic element 12143 can always deform in the vertical direction, effectively preventing the first elastic element 12143 from deviating, which is conducive to further improving the stability of the movement of the top rod 1212.

[0076] like Figure 3 and Figure 5 As shown, in an optional embodiment, the clamping assembly 122 further includes a second elastic assembly 1224; the second elastic assembly 1224 includes a second fixed block 12241, a second movable block 12242, and a second elastic member 12243. The second movable block 12242 is disposed on the mounting bracket 1221, the second fixed block 12241 is disposed on the mounting plate 1121, one end of the second elastic member 12243 is connected to the second fixed block 12241, and the other end of the second elastic member 12243 is connected to the second movable block 12242.

[0077] Specifically, the second movable block 12242 and the second fixed block 12241 are arranged parallel to each other at intervals along the height direction, and the mounting frame 1221 and the mounting plate 1121 are arranged at intervals. The mounting frame 1221 can be movably connected to the mounting plate 1121 via a connecting block, and the mounting frame 1221 can move slightly in the vertical direction. The second movable block 12242 is installed at the bottom of the mounting frame 1221, and the second movable block 12242 can be fixed to the mounting frame 1221 by welding or screwing, and the second movable block 12242 can move synchronously with the mounting frame 1221. The second fixed block 12241 is installed at the top of the mounting plate 1121, and the second fixed block 12241 can be fixed to the mounting plate 1121 by welding or screwing.

[0078] The second elastic element 12243 can be a cylindrical spring. One end of the second elastic element 12243 is connected to the second fixed block 12241, and the other end of the second elastic element 12243 is connected to the second movable block 12242. When the mounting bracket 1221 moves upward in the vertical direction, it drives the second movable block 12242 to move upward, and the second elastic element 12243 is compressed. When the mounting bracket 1221 moves downward in the vertical direction, it drives the second movable block 12242 to move downward, and the second elastic element 12243 gradually returns to its initial state.

[0079] The push rod 1212 moves vertically upwards. After the top surface of the battery cell contacts the pressure head 1222, the push rod 1212 continues to move upwards, causing the mounting bracket 1221 to move slightly upwards. The mounting bracket 1221 then moves the second movable block 12242 upwards, compressing the second elastic element 12243 until the top surface of the battery cell is pressed against the pressure head 1222, ensuring that the push rod 1212 and the pressure head 1222 clamp the battery cell. Simultaneously, if the push rod 1212 moves excessively vertically due to unforeseen circumstances, the deformation of the second elastic element 12243 under pressure can prevent the pressure head 1222 from damaging the battery cell.

[0080] In this embodiment of the invention, the second elastic member 12243 can provide a certain floating space for the clamping assembly 122, so that the pressure head 1222 can press against the battery cell, ensuring the stability of clamping the battery cell, and at the same time effectively preventing the pressure head 1222 from damaging the battery cell.

[0081] like Figure 2 As shown, in an optional embodiment, the support member 112 further includes a limiting block 1123; the limiting block 1123 is disposed on the side of the support plate 1122 facing the pressing assembly 122, the limiting block 1123 is used to adapt to the shape of the cup, the limiting block 1123 is used to limit the position of the cup, and the cup is used to place the battery cell.

[0082] Specifically, the limiting block 1123 is installed on the top surface of the support plate 1122. The limiting block 1123 is adapted to the shape of the cup. The central axis of the limiting block 1123 is consistent with the axis of the first through hole of the support plate 1122. The limiting block 1123 is used to limit and fix the position of the cup, so that the battery cell placed in the cup can be coaxial with the lifting assembly 121 and the pressing assembly 122.

[0083] Furthermore, to ensure a tighter fit between the cup holder and the limiting block 1123, a magnetic piece is provided on the peripheral wall of the limiting block 1123, and the outer wall of the cup holder is provided with a material that attracts the magnetic piece, such as a metal or alloy material like iron, nickel, or cobalt. The cup holder and the limiting block 1123 are firmly attached, effectively preventing the battery cell from shifting during dust removal and ensuring the quality of dust removal.

[0084] In an optional embodiment, a plurality of first clamping mechanisms 12 are provided, and the plurality of first clamping mechanisms 12 are arranged sequentially at intervals along the rotation direction of the first turret mechanism 11.

[0085] Specifically, multiple first clamping mechanisms 12 are arranged sequentially along the rotation direction of the first turret mechanism 11. Multiple mounting plates 1121 are provided around the rotating body 111. The pressing component 122 in each first clamping mechanism 12 is connected to the mounting plate 1121 in a one-to-one correspondence. The lifting component 121 in each first clamping mechanism 12 is connected to the mounting plate 1121 in a one-to-one correspondence. The bottom of each lifting component 121 abuts against the annular track 113.

[0086] like Figure 1 As shown, the number of dust removal mechanisms 13 is set according to requirements. For example, the first turret mechanism 11 has four dust removal stations arranged circumferentially, and the number of dust removal mechanisms 13 is four. The four dust removal mechanisms 13 are set at the four dust removal stations, and each dust removal mechanism 13 corresponds to a first clamping mechanism 12. The first turret mechanism 11 drives multiple first clamping mechanisms 12 to rotate to the dust removal station. The four first clamping mechanisms 12 corresponding to the four dust removal stations clamp four battery cells to be dusted. The dust removal operation of four battery cells can be performed simultaneously through the four dust removal mechanisms 13, which is conducive to further improving the dust removal efficiency.

[0087] like Figure 1 and Figure 6 As shown, in an optional embodiment, the rejection device includes a first rejection mechanism 31 and a second rejection mechanism 32; the first rejection mechanism 31 is located on one side of the dust removal device 1 and is used to reject defective battery cells before dust removal; the second rejection mechanism 32 is located on one side of the first detection device 2 and is used to transport battery cells that pass the inspection after dust removal to the good product output chain plate 7, and to transport battery cells that fail the inspection after dust removal to the defective product output chain plate 8.

[0088] Specifically, the feed chain plate 4 is located on one side of the dust removal device 1, and a feed turntable 5 is provided between the feed chain plate 4 and the dust removal device 1. A second detection device, including a height detector, is located above the feed turntable 5. The feed chain plate 4 transports the battery cells to be dusted to the feed turntable 5. The height detector detects the height of the battery cells before dust removal. The first good battery cells that meet the height requirements are transferred to the first turret mechanism 11 by the rotation of the feed turntable 5. The first rejection mechanism 31 rejects the first good battery cells that do not meet the height requirements. The first rejection mechanism 31 can be a push rod to push the first good battery cells that do not meet the height requirements off the feed turntable 5.

[0089] The second rejection mechanism 32 is located on one side of the first detection device 2. After the battery cells on the first detection device 2 complete image acquisition, they are transferred to the sorting turntable 6. The second rejection mechanism 32 includes a movable paddle 321 and a drive push rod 322. The movable paddle 321 is installed on the end face of the sorting turntable 6, and the drive push rod 322 has a reciprocating stroke toward the corresponding unloading station. The drive push rod 322 is used to drive the movable paddle 321. The drive push rod 322 pushes the good battery cells that meet the cleanliness requirements into the first unloading turntable through the movable paddle 321, and is further transferred to the good product output chain plate 7 by the rotation of the first unloading turntable. The drive push rod 322 pushes the defective battery cells that do not meet the cleanliness requirements into the second unloading turntable through the movable paddle 321, and is further transferred to the defective product output chain plate 8 by the rotation of the second unloading turntable.

[0090] like Figure 7 As shown, the present invention also provides a control method based on the above-mentioned turret-type cylindrical battery cell large-area dust removal equipment, comprising:

[0091] Step 910: Obtain the target height threshold and the actual height information of the battery cell.

[0092] In this step, the target height threshold can be either the acceptable height range for battery cells or the height range for a specific model of battery cell. The controller uses a height detector to detect the actual height of the passing battery cells.

[0093] Step 920: Based on the actual height information and the target height threshold, control the rejection device to reject the first defective battery cell and send the first good battery cell into the first turret mechanism 11 of the dust removal device 1.

[0094] In this step, the controller compares the actual height information of the battery cell with the target height threshold. The battery cell that meets the target height threshold is the first good battery cell, and the battery cell that does not meet the target height threshold is the second good battery cell. The first good battery cell is transferred to the first turret mechanism 11 of the dust removal device 1 through the feeding turntable.

[0095] Step 930: Control the dust removal mechanism 13 to remove dust from the first good battery cell.

[0096] In this step, the first clamping mechanism 12, driven by the first turret mechanism 11, brings the first good battery cell to the dust removal station, and the dust removal mechanism 13 removes dust from the circumferential surface of the first good battery cell.

[0097] Step 940: Control the first clamping mechanism 12 to send the dust-removed first good product battery cell into the first testing device 2, and obtain the actual dust removal image of the first good product battery cell after dust removal.

[0098] In this step, the first good battery cell after dust removal is sent to the first detection device 2. The image acquisition mechanism 21 acquires the actual dust removal image of the first good battery cell. The actual dust removal image is the surface image of the first good battery cell after dust removal, which is obtained by the image acquisition mechanism 21. The actual dust removal image includes the dust removal part of the first good battery cell.

[0099] Step 950: Based on the actual dust removal image, control the rejection device to reject the second batch of defective battery cells and send the second batch of good battery cells to the next work station.

[0100] In this step, the battery cells held on the first detection device 2 are transferred to the sorting turntable after being detected. The controller compares the actual dust removal image with the target dust removal image, or directly performs intelligent detection on the actual dust removal image to identify the cleanliness of the circumferential surface of the first good battery cell. The first good battery cell that meets the cleanliness requirements is designated as the second good battery cell, and the first good battery cell that does not meet the cleanliness requirements is designated as the second bad battery cell.

[0101] The second rejection mechanism 32 pushes the second good battery cell that meets the cleanliness requirements into the first feeding turntable, and further transfers it to the good output chain plate 7 through the rotation of the first feeding turntable; the second rejection mechanism 32 pushes the second bad battery cell that does not meet the cleanliness requirements into the second feeding turntable, and further transfers it to the bad output chain plate 8 through the rotation of the second feeding turntable.

[0102] The control method for a large-area dust removal device for turret-type cylindrical battery cells provided by this invention compares the battery cells before and after dust removal, sends the battery cells that meet the requirements to the next process, and removes the battery cells that do not meet the requirements, thereby ensuring the dust removal quality of the battery cells and improving the dust removal efficiency.

[0103] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
