[0002] During battery processing, the cells undergo mechanical / ultrasonic flattening, encapsulation, casing, collector plate welding, and sealing welding before they are assembled into batteries. To ensure high battery yield, the battery casing must be cleaned before the cells are casing to remove dust and other debris adhering to the inner walls.

[0055] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0056] The following combination Figures 1-10 , the battery shell dust removal system based on the turret provided by the embodiment of the invention is described in detail through specific embodiments and application scenarios.

[0057] like Figure 1 、 Figure 2 、 Figure 3 and Figure 9 As shown, an embodiment of the present invention provides a battery shell dust removal system based on a turret, comprising: a turret 2, a battery shell carrier 5, a loading unit 6, a dust removal unit 1 and a first unloading unit 7;

[0058] The loading unit 6, the dust removal unit 1 and the first unloading unit 7 are sequentially arranged along the circumference of the turret 2; the battery shell carrier 5 is used to move to the positions corresponding to the loading unit 6, the dust removal unit 1 and the first unloading unit 7 in sequence under the drive of the turret 2;

[0059] The battery shell carrier 5 includes an adapter frame 51, a fixing seat 52 and a transfer mechanism 53; the adapter frame 51 is connected to the turret 2, and the fixing seat 52 and the transfer mechanism 53 are respectively provided on the adapter frame 51; the fixing seat 52 is used to fix the support cup 20, and the support cup 20 is used to support the vertically distributed battery shell 10;

[0060] The loading unit 6 is used to load the battery shell 10; the dust removal unit 1 is used to remove dust from the battery shell 10; the transfer mechanism 53 is used to separate the battery shell 10 that has completed dust removal from the support cup 20; the first unloading unit 7 is used to receive the battery shell 10 from the transfer mechanism 53 and unload the battery shell 10.

[0061] It is understandable that the turret 2 includes a tower body 21 and a rotary drive mechanism 22, and the rotary drive mechanism 22 and the tower body 21 are power-coupled to drive the tower body 21 to rotate around its central axis. The battery shell carrier 5 is detachably arranged on the peripheral wall of the tower body 21. Multiple battery shell carriers 5 can be provided, and multiple battery shell carriers 5 are arranged in sequence along the circumference of the turret 2. This design allows each battery shell carrier 5 to pass through the dust removal unit 1 in sequence during one rotation of the turret 2, thereby completing the dust removal operation of multiple battery shells 10 at one time based on the dust removal unit 1, which not only has high dust removal efficiency but also occupies little site space.

[0062] For the battery shell carrier 5, the adapter frame 51 has a first side wall and a second side wall arranged in a reverse direction. The first side wall is connected to the turret 2, and the second side wall is connected to the fixing seat 52. The fixing seat 52 is used to fix the vertically distributed support cups 20. The transfer mechanism 53 and the fixing seat 52 are respectively arranged on the side of the adapter frame 51 away from the turret 2. The transfer mechanism 53 can be connected to the battery shell 10 and control the battery shell 10 to move upward to achieve separation of the battery shell 10 from the support cup 20. Among them, the transfer mechanism 53 can be a robotic arm, a clamp, etc., which is not specifically limited.

[0063] like Figure 8 As shown, the support cup 20 includes a cup body 201 and a magnet 202; the fixing seat 52 is connected to part of the peripheral wall of the cup body 201, the cup body 201 is cylindrical, the magnet 202 is arranged in the cup body 201, and the inner wall of the cup body 201 is provided with a retaining ring, which is coaxially arranged with the cup body 201 and is located near the bottom end of the cup body 201; the battery shell 10 is inserted into the support cup 20, and the retaining ring is supported on the bottom end of the battery shell 10. This design not only uses the support cup 20 to support the battery shell 10, but also facilitates the dust removal head 141 to first pass through the retaining ring and then be inserted into the battery shell 10 to remove dust from the battery shell 10.

[0064] Furthermore, an annular groove 203 is provided at the bottom end of the cup body 201. The annular groove 203 extends along the circumference of the cup body 201. A radio frequency tag is installed in the annular groove 203. The radio frequency tag can be read by a reader / writer to bind information between the cup 20 and the battery shell 10 it supports, and also facilitate the tracking of the position of the cup 20.

[0065] The loading unit 6 may be a robotic arm known in the art, such as a six-axis robotic arm, which picks up the battery shell 10 and transfers the battery shell 10 to the tray 20 stored on the fixing seat 52 .

[0066] like Figure 2 As shown, the loading unit 6 can also be configured to include a loading conveyor line 61, a loading turntable 62, and a loading enclosure 63. The loading conveyor line 61 can be a chain plate conveyor. The loading turntable 62 is rotatably disposed on one side of the turret 2. The loading enclosure 63 is circumferentially disposed outside the loading turntable 62. The output end of the loading conveyor line 61 extends to the lower side of the loading turntable 62 and the loading enclosure 63. The loading turntable 62 is provided with a plurality of notch-shaped shifting openings along the circumference. The plurality of shifting openings are symmetrically distributed with respect to the center of the loading turntable 62 in the same direction.

[0067] In actual application, the loading turntable 62 and the turret 2 both rotate relative to the vertically distributed rotation axis, and the loading turntable 62 is arranged on one side of the turret 2; the turret 2 is configured to rotate in a counterclockwise direction, and the loading turntable 62 is configured to rotate in a clockwise direction.

[0068] At the same time, the loading conveyor line 61 is used to realize the transportation of a single row of trays 20, and each tray 20 is used to support a vertically distributed battery shell 10; when the tray 20 is transferred to between the loading turntable 62 and the loading enclosure 63 under the transportation of the loading conveyor line 61, the gear mouth of the loading turntable 62 is clamped on the side of the tray 20 facing the loading turntable 62, and the loading enclosure 63 is limited to the side of the tray 20 away from the loading turntable 62, so that under the drive of the loading turntable 62, the tray 20 supporting the battery shell 10 is transferred to the fixed seat 52 of the battery shell carrier 5.

[0069] Furthermore, the dust removal unit 1 can adjust the position of the dust removal head 141 through a driving mechanism to drive the dust removal head 141 to reciprocate in the vertical direction, thereby controlling the dust removal head 141 to insert and withdraw from the battery shell 10 to complete the dust removal operation of the battery shell 10.

[0070] The dust removal head 141 can be a brush, a blowing head, or a dust extraction head; the maximum outer diameter of the dust removal head 141 should be smaller than the inner diameter of the battery shell 10 to ensure that when the battery shell 10 rotates along with the turret 2, the dust removal head 141 can be inserted and extracted relative to the battery shell 10 in the vertical direction.

[0071] Furthermore, the first unloading unit 7 can adopt a robotic arm well known in the art, for example, a six-axis robotic arm; after the transfer mechanism 53 separates the dust-removed battery shell 10 from the tray 20, the battery shell 10 can be picked up by the first unloading unit 7 and unloading operations can be performed on the battery shell 10.

[0072] For the battery shell dust removal system of the present invention, by sequentially arranging the loading unit 6, the dust removal unit 1 and the first unloading unit 7 along the circumference of the turret 2, when the battery shell carrier 5 rotates along with the turret 2, it can be ensured that the battery shell carrier 5 reaches the positions corresponding to the loading unit 6, the dust removal unit 1 and the first unloading unit 7 in sequence. During this process, the loading unit 6 first performs the loading operation of the battery shell 10, and realizes the use of the fixed seat 52 of the battery shell carrier 5 as a carrier, and the vertically distributed battery shell 10 is placed using the support cup 20. Then, the dust removal unit 1 is used to perform dust removal on the battery shell 10, and then the transfer mechanism 53 of the battery shell carrier 5 separates the dust-removed battery shell 10 from the support cup 20 on the fixed seat 52. Finally, the first unloading unit 7 is used to receive the battery shell 10 from the transfer mechanism 53, and the battery shell 10 is unloaded.

[0073] As can be seen from the above, the present invention can sequentially perform the loading, dust removal and unloading processes of the battery shell 10 , thereby achieving efficient dust removal of the vertical battery shell 10 and reducing the occupation of site space.

[0074] In some embodiments, as Figure 3 、 Figure 4 and Figure 5 As shown, the dust removal unit 1 includes a fixed frame 11, a lifting frame 12, an elastic member 13 and a dust removal member 14; the fixed frame 11 is arranged on one side of the turret 2, and the lifting frame 12 is movably arranged on the fixed frame 11 along the vertical direction; the dust removal member 14 includes a dust removal head 141, which is arranged on the lifting frame 12, and the elastic member 13 is arranged between the fixed frame 11 and the lifting frame 12;

[0075] like Figure 4 and Figure 6 As shown, a first rolling member 120 is provided on the lifting frame 12, and the first rolling member 120 is in rolling contact with the first cam track 3 on the turret 2; the lifting frame 12 is used to lift and lower between a first height and a second height relative to the fixed frame 11 under the elastic force of the elastic member 13 and the lifting and lowering guidance of the first cam track 3; when the lifting frame 12 is at the first height, the dust removal head 141 is inserted into the battery shell 10 to remove dust from the battery shell 10; when the lifting frame 12 is at the second height, the dust removal head 141 is separated from the battery shell 10.

[0076] It is understandable that a sliding guide structure is provided between the fixed frame 11 and the lifting frame 12. The sliding guide structure includes a slide rail and a slide groove. The slide rail and the slide groove slide together in the vertical direction to guide the lifting frame 12 to rise and fall relative to the fixed frame 11 in the vertical direction.

[0077] The first cam track 3 is disposed on the underside of the turret 2. The turret 2 can drive the first cam track 3 to rotate about its rotation axis. The first rolling element 120 can only be raised and lowered vertically along with the lifting frame 12 and cannot rotate relative to the turret 2. During the rotation of the turret 2, the turret 2 drives the vertically arranged battery casings 10 to rotate, and the first rolling element 120 rolls along the extension direction of the first cam track 3.

[0078] Specifically, the elastic member 13 is used to apply an elastic pulling force vertically downward to the lifting frame 12; the first cam track 3 is used to drive the first rolling member 120 to drive the lifting frame 12 to rise, so that the lifting frame 12 rises from the second height to the first height, ensuring that the dust removal head 141 can be inserted into the battery case 10 from the bottom up to remove dust from the battery case 10. In the process of the lifting frame 12 rising from the second height to the first height, the elastic member 13 is gradually stretched and switches from the initial state to the stretched state, storing a large amount of elastic potential energy.

[0079] At the same time, the first cam track 3 can also guide the first rolling member 120 to descend. During the descent of the first rolling member 120, the elastic member 13 will recover from the stretched state to the initial state, thereby driving the lifting frame 12 to descend, and then the lifting frame 12 drives the dust removal head 141 to separate from the battery shell 10.

[0080] Optionally, the first rolling element 120 may be a roller or a rolling bearing, and the first rolling element 120 is rotatably provided on the lifting frame 12 around a horizontal axis.

[0081] Optionally, the elastic member 13 may be a spring, which is vertically distributed, with the upper end of the spring connected to the bottom end of the lifting frame 12 , and the lower end of the spring connected to the bottom end of the fixing frame 11 .

[0082] At the same time, multiple elastic members 13 can be provided, and multiple elastic members 13 can be arranged side by side. This design can ensure that the lifting frame 12 can be stably and reliably lowered from the first height to the second height to achieve the separation of the dust removal head 141 from the battery shell 10.

[0083] As can be seen from the above, the dust removal unit 1 is configured with a fixed frame 11, a lifting frame 12, an elastic member 13 and a dust removal member 14. Under the cooperation of the elastic member 13 and the first cam track 3 on the turret 2, the lifting frame 12 can drive the dust removal member 14 to move up and down relative to the fixed frame 11. It can ensure that the dust removal head 141 is inserted and withdrawn relative to the battery shell 10 in the vertical direction during the rotation of the battery shell 10 along with the turret 2, thereby realizing the dust removal operation on the inner wall of the battery shell 10. This design does not require manual participation, and the lifting and lowering control of the dust removal head 141 can be achieved through a simple mechanical linkage. It can conveniently perform dust removal on the vertically distributed battery shells 10, ensuring the dust removal efficiency of the battery shells 10.

[0084] At the same time, compared with the horizontal dust removal design of the battery shell 10, the dust removal design of the present invention not only simplifies the dust removal control process, but also helps to reduce the occupation of site space.

[0085] In some embodiments, as Figure 4 and Figure 8 As shown, the dust removal head 141 has an inner cavity and air holes connected to the inner cavity. The air holes are provided on the surface of the dust removal head 141, and the inner cavity is configured to be connected to the blowing device and / or the negative pressure dust collecting device.

[0086] Specifically, the dust removal head 141 is cylindrical, and the battery case 10 is disposed with its bottom opening open. The bottom end of the dust removal head 141 is connected to the lifting frame 12, so that the dust removal head 141 can be vertically inserted from the bottom to the top of the battery case 10 under the drive of the lifting frame 12. After completing the dust removal operation on the battery case 10, the dust removal head 141 can also be driven by the lifting frame 12 to leave the battery case 10 from the bottom side of the battery case 10.

[0087] At the same time, multiple air holes are provided on the top and peripheral walls of the dust removal head 141. When the inner cavity is connected to the air blowing device, the compressed gas input by the air blowing device can be distributed to each air hole through the inner cavity, and then sprayed from the air holes to the inner wall of the battery shell 10 to remove dust from the inner wall of the battery shell 10; when the inner cavity is connected to the negative pressure dust collection device, the air and dust in the battery shell 10 can enter the negative pressure dust collection device through the air holes and the inner cavity in sequence under the drive of negative pressure.

[0088] In some embodiments, as Figure 5 and Figure 8 As shown, the dust removal component 14 also includes: a first ventilation joint 142 and a second ventilation joint 143; the inner cavity is connected to the first ventilation joint 142 and the second ventilation joint 143 respectively; the first ventilation joint 142 is configured to be connected to the blowing device; the second ventilation joint 143 is configured to be connected to the negative pressure dust collection device.

[0089] Further, if Figure 4 As shown, in order to automatically perform dust removal on the battery shell 10 and ensure the dust removal effect, the dust removal unit 1 is further provided with a detection member 15, the detection member 15 is connected to the control module, and the control module is electrically connected to the first ventilation connector 142 and the second ventilation connector 143 respectively;

[0090] The detection member 15 is used to detect the lifting height of the lifting frame 12; the control module is used to control the first ventilation joint 142 and the second ventilation joint 143 to be connected in sequence when the detection member 15 detects that the lifting frame 12 is at a first height.

[0091] Specifically, the detection part 15 can adopt a photoelectric switch and be arranged on the fixed frame 11; the lifting frame 12 is provided with a sensor sheet. When the sensor sheet rises along with the lifting frame 12 and reaches a position that can trigger the photoelectric switch, the lifting frame 12 is at a first height. At this time, the control module first controls the first ventilation joint 142 to be turned on according to the feedback signal, so that the dust removal head 141 blows air into the battery shell 10, and sets the blowing time of the dust removal head 141.

[0092] When the blowing time reaches the preset value, the control module controls the first ventilation connector 142 to be cut off and controls the second ventilation connector 143 to be turned on, so that the negative pressure dust collection equipment collects the dust in the battery shell 10 through the dust removal head 141, thereby completing the automatic dust removal operation of the battery shell 10.

[0093] The first ventilation connector 142 and the second ventilation connector 143 are both configured with solenoid valves capable of performing opening and closing control in response to a control module. The control module may be a PLC controller or a single chip microcomputer.

[0094] In some embodiments, as Figure 4 As shown, the lifting frame 12 includes a lifting seat 121, a carrying platform 122 and a suspension 123; the lifting seat 121 is arranged on the side of the carrying platform 122 away from the turret 2, and is movably arranged on the fixed frame 11 along the vertical direction; the suspension 123 is arranged on the side of the carrying platform 122 facing the turret 2, and is connected to the first rolling member 120; the dust removal head 141 is arranged on the carrying platform 122.

[0095] It is understandable that the lifting seat 121 and the suspension 123 are respectively vertically arranged on the lower side of the carrying platform 122, so that the upper side of the carrying platform 122 is exposed, and the dust removal head 141 is arranged on the carrying platform 122 in a vertically distributed manner. This design is not only conducive to the rolling cooperation between the first rolling member 120 and the first cam track 3 on the turret 2 without interference with each other, but also conducive to the carrying platform 122 supporting the dust removal head 141 to be smoothly inserted into the battery shell 10 or pulled out from the battery shell 10.

[0096] The above-mentioned sliding guide structure is provided between the lifting seat 121 and the lifting frame 12 , and the sensor sheet can be provided on the lifting seat 121 to trigger the photoelectric switch on the fixing frame 11 .

[0097] In some embodiments, as Figure 3 and Figure 6 As shown, the first cam track 3 includes a plurality of convex sections 31 and a plurality of concave sections 32 ; the plurality of convex sections 31 and the plurality of concave sections 32 are alternately connected in sequence along the circumference of the turret 2 .

[0098] exist Figure 6The curved arrow in the figure indicates the rotation direction of the turret 2. Since the dust removal unit 1 remains in the same position on one side of the turret 2, as the turret 2 drives the first cam track 3 to rotate in this direction, the upper convex section 31 and the lower concave section 32 alternately contact the first rolling element 120, and this cycle continues. When the first rolling element 120 moves along the upper convex section 31, the upper convex section 31 is used to drive the first rolling element 120 to drive the lifting frame 12 to rise, thereby allowing the dust removal head 141 to pass through the support cup 20 and the battery housing 10 from bottom to top. When the first rolling element 120 moves along the lower concave section 32, the elastic member 13 is used to drive the lifting frame 12 to descend, thereby allowing the dust removal head 141 to leave the battery housing 10 and the support cup 20 from top to bottom.

[0099] Since multiple convex sections 31 and multiple concave sections 32 are alternately connected in sequence along the circumference of the turret 2, when the first rolling element 120 rolls along the first cam track 3, the first rolling element 120 will pass through the alternatingly arranged convex sections 31 and concave sections 32 in sequence, so that based on the mutual cooperation between the first cam track 3 and the elastic member 13, the lifting frame 12 can be lifted and lowered reciprocatingly.

[0100] In this way, when each battery shell 10 is evenly distributed along the circumference of the turret 2 and rotates at a set speed driven by the turret 2, the dust removal head 141 can be driven to move up and down at a set position by the lifting frame 12 to realize dust removal operations on each battery shell 10 in turn.

[0101] Further, if Figure 6 As shown, in order to ensure that the dust removal head 141 can stably perform reciprocating lifting motion in the vertical direction, the upper convex section 31 and the lower concave section 32 are both arc-shaped (for example, circular arc-shaped), so that the first cam track 3 extends along a sinusoidal trajectory in the circumferential direction of the turret 2.

[0102] In some embodiments, as Figure 7 As shown, in order to facilitate the fixation of the support cup 20 , the fixing base 52 includes a magnetic holder 521 . The magnetic holder 521 is used to be clamped on at least a portion of the peripheral wall of the support cup 20 and magnetically attracted to the support cup 20 .

[0103] It is understood that the magnetic holder 521 is provided with a snap-fit ​​structure that can be snap-fitted to the peripheral wall of the cup 20 based on the snap-fit ​​structure. Furthermore, the magnetic holder 521 can also be provided with a magnetic attraction member that can attract the magnet 202 in the cup 20 to ensure that the cup 20 is securely secured to the snap-fit ​​structure. The magnetic attraction member and the magnet 202 in the cup 20 can both be neodymium iron boron magnets to ensure a strong magnetic attraction between the magnetic holder 521 and the cup 20.

[0104] Further, if Figure 7As shown, an arc-shaped slot 5211 is provided on the side of the magnetic holder 521 facing away from the turret 2, and an arc-shaped rib 5212 is provided on the upper end of the magnetic holder 521. The arc-shaped rib 5212 is located on the slot wall of the arc-shaped slot 5211 and extends along the extension direction of the arc-shaped slot 5211; wherein, the slot wall of the arc-shaped slot 5211 is used to fit with the peripheral wall of the support cup 20, and the arc-shaped rib 5212 is used to stop the top surface of the support cup 20.

[0105] It is understandable that the groove wall of the arc-shaped groove 5211 is extended circumferentially relative to the central axis of the support cup 20 to ensure that the groove wall of the arc-shaped groove 5211 can fit the peripheral wall of the support cup 20 .

[0106] At the same time, by setting an arc-shaped retaining edge 5212 for stopping the top surface of the support cup 20, the support cup 20 can be positioned in the vertical direction. During the dust removal process of the battery shell 10, the support cup 20 can be effectively prevented from moving upward under the touch of the lifting frame 12.

[0107] Furthermore, when the fixing seat 52 of the battery shell carrier 5 is configured as a magnetic holder 521, in order to ensure the reliability of the magnetic holder 521 fixing the support cup 20, a fence can also be configured on the outside of the turret 2. The fence extends along the circumference of the turret 2, and the fence abuts against the peripheral wall of the support cup 20 toward one side of the turret 2.

[0108] In some embodiments, as Figure 7 As shown, the fixing seat 52 also includes a limit card seat 522, which is arranged on the upper side of the magnetic card seat 521. The limit card seat 522 is provided with an arc-shaped notch on the side away from the turret 2. The arc-shaped notch can fit with the peripheral wall of the battery shell 10. The limit card seat 522 can also be configured to be magnetically attracted to the battery shell 10 to ensure that the battery shell 10 is reliably arranged in the support cup 20 during the dust removal operation.

[0109] In some embodiments, as Figure 3 As shown, the transfer mechanism 53 includes a sliding frame 531, a clamping claw 532 and a second rolling member 533; the sliding frame 531 is located on the upper side of the fixed base 52 and is movably provided on the adapter frame 51 along the vertical direction; the clamping claw 532 and the second rolling member 533 are respectively provided on the sliding frame 531;

[0110] The turret 2 is provided with a second cam track 4 fixed along the circumference. The second rolling member 533 is in rolling contact with the second cam track 4 and can drive the sliding frame 531 to drive the clamping jaw 532 to rise and fall under the guidance of the second cam track 4, so that the clamping jaw 532 clamps the battery shell 10 and controls the separation of the battery shell 10 from the tray 20.

[0111] It is understandable that a sliding guide structure is provided between the sliding frame 531 and the adapter frame 51. The sliding guide structure includes a sliding rail and a sliding groove. The sliding rail and the sliding groove slide together in the vertical direction to guide the sliding frame 531 to rise and fall relative to the adapter frame 51 in the vertical direction.

[0112] The second rolling member 533 is disposed at the upper end of the sliding frame 531 and is capable of rolling along the extension direction of the second cam track 4. The second rolling member 533 may be a roller or a rolling bearing. The clamping jaw 532 may be a pneumatic or electric clamping jaw. The clamping end of the clamping jaw 532 is vertically downwardly disposed and corresponds to the upper end of the battery case 10.

[0113] In some embodiments, as Figure 3 As shown, the second cam track 4 includes a lower convex section 41 and an upper concave section 42; the lower convex section 41 and the upper concave section 42 are connected, and the lower convex section 41 corresponds to the position where the dust removal unit 1 is arranged; when the second rolling member 533 moves along the lower convex section 41, the clamping jaw 532 is at a height that can clamp the battery shell 10; when the second rolling member 533 moves along the upper concave section 42, the clamping jaw 532 clamps the battery shell 10, and the battery shell 10 is separated from the tray 20.

[0114] It is understood that both the lower convex section 41 and the upper concave section 42 have horizontal sections. When the second rolling member 533 moves along the horizontal section of the lower convex section 41, the clamping jaws 532 are at a third height, with the clamping ends of the clamping jaws 532 located on opposite sides of the battery case 10. When the second rolling member 533 moves from the horizontal section of the lower convex section 41 toward the upper concave section 42, the clamping jaws 532 clamp the battery case 10 and move it upward. When the second rolling member 533 moves to the horizontal section of the upper concave section 42, the clamping jaws 532 are at a fourth height, thereby separating the battery case 10 from the tray 20.

[0115] In some embodiments, multiple dust removal units 1 are provided, and the multiple dust removal units 1 are arranged in sequence along the circumference of the turret 2. When the second cam track 4 includes a lower convex section 41 and an upper concave section 42, the multiple dust removal units 1 are arranged opposite to the horizontal section of the lower convex section 41.

[0116] Since each dust removal unit 1 can perform a dust removal process on the battery shell 10 once, when the battery shell 10 rotates circumferentially driven by the turret 2, multiple dust removal units 1 can repeatedly perform dust removal processes on the same battery shell 10 multiple times to ensure the dust removal effect of the battery shell 10.

[0117] In some embodiments, as Figure 9As shown, the first unloading unit 7 includes a first unloading turntable 71, a supporting seat 72 and a first enclosure 73; the supporting seat 72 is arranged around the first unloading turntable 71 and can rotate under the drive of the first unloading turntable 71; the first enclosure 73 is arranged around the outer side of the first unloading turntable 71;

[0118] When the battery shell carrier 5 moves to the position corresponding to the first unloading unit 7, the transfer mechanism 53 and the battery shell 10 are separated, and the supporting seat 72 supports the bottom end of the battery shell 10 and the side of the battery shell 10 facing the first unloading turntable 71. The first enclosure 73 is limited to the side of the battery shell 10 away from the first unloading turntable 71, so that the unloading operation of the battery shell 10 can be carried out under the drive of the first unloading turntable 71.

[0119] Specifically, since there are multiple battery shell carriers 5 evenly distributed along the circumference of the turret 2, in order to facilitate the unloading operation of the battery shells 10 that have been dust-removed on each battery shell carrier 5, multiple supporting seats 72 can be correspondingly provided, and the multiple supporting seats 72 are evenly distributed along the circumference of the first unloading turntable 71.

[0120] In actual application, the first unloading turntable 71 and the turret 2 both rotate relative to the vertically distributed rotation axis, and the first unloading turntable 71 is arranged on one side of the turret 2; the turret 2 is configured to rotate in a counterclockwise direction, and the first unloading turntable 71 is configured to rotate in a clockwise direction.

[0121] When the battery shell carrier 5 moves to the position corresponding to the first unloading unit 7, the clamping jaw 532 on the battery shell carrier 5 is opposite to a supporting seat 72 on the first unloading unit 7, and the clamping jaw 532 switches from a closed state to an open state to release the battery shell 10 on the supporting seat 72; as the first unloading turntable 71 continues to rotate, the battery shell 10 will leave the turret 2 and rotate along with the first unloading turntable 71 under the limitation of the supporting seat 72 and the first enclosure 73, and can be transferred from the first unloading turntable 71 to the battery cell shell entry station, and the battery shell 10 is placed on the outside of the battery cell at the battery cell shell entry station.

[0122] In some embodiments, as Figure 9 As shown, the supporting seat 72 includes a magnetic seat body 721 and a support plate 722; the magnetic seat body 721 is connected to the first unloading turntable 71, and an arc-shaped notch is provided at one end of the magnetic seat body 721 away from the first unloading turntable 71, and the wall surface of the arc-shaped notch is used to stick to the peripheral wall of the battery shell 10 and be magnetically attracted to the battery shell 10; the support plate 722 is provided in the arc-shaped notch and extends along the lower side edge of the arc-shaped notch; the support plate 722 is used to support the bottom end of the battery shell 10.

[0123] It is understood that since the battery case 10 is generally constructed of a steel shell, the support base 72 is configured as a magnetic base 721 and a support plate 722. This allows the support base 721 to not only support the battery case 10 but also to attract the battery case 10, thereby ensuring reliable support of the battery case 10. The magnetic base 721 may be assembled from a plastic base and a permanent magnet embedded in the plastic base.

[0124] At the same time, by setting an arc-shaped notch at the end of the magnetic base 721 away from the first unloading turntable 71, it is not only convenient for the arc-shaped notch on the supporting seat 72 to cooperate with the arc-shaped slot 5211 on the fixing seat 52, thereby realizing the transfer of the battery shell 10 from the fixing seat 52 to the supporting seat 72, but also the wall surface of the arc-shaped notch and the support plate 722 can form a supporting structure adapted to the battery shell 10, thereby ensuring the reliability of supporting the battery shell 10.

[0125] In some embodiments, as Figure 1 and Figure 10 As shown, the battery shell dust removal system further includes: a second unloading unit 8, a loading unit 6, a dust removal unit 1, a first unloading unit 7 and a second unloading unit 8 are sequentially arranged along the circumference of the turret 2;

[0126] The second unloading unit 8 includes a second unloading turntable 81 and a second enclosure 82; the second unloading turntable 81 is provided with a plurality of gear shifting openings along the circumference, and the second enclosure 82 is arranged around the outer side of the second unloading turntable 81;

[0127] When the battery shell carrier 5 moves to the position corresponding to the second unloading unit 8, the tooth mouth is clamped on the side of the support cup 20 facing the second unloading turntable 81, and the second enclosure 82 is limited to the side of the support cup 20 away from the second unloading turntable 81, so that the unloading operation of the support cup 20 can be performed under the drive of the second unloading turntable 81.

[0128] It is understandable that the battery shell dust removal system first uses the loading unit 6 to load the battery shell 10, and then uses the dust removal unit 1 to perform dust removal on the battery shell 10. After the transfer mechanism 53 of the battery shell carrier 5 separates the dust-removed battery shell 10 from the support cup 20 on the fixed seat 52, the first unloading unit 7 is used to unload the battery shell 10, and finally the second unloading unit 8 is used to unload the support cup 20.

[0129] In actual application, the second unloading turntable 81 and the turret 2 both rotate relative to the vertically distributed rotation axis, and the second unloading turntable 81 is arranged on one side of the turret 2; the turret 2 is configured to rotate in a counterclockwise direction, and the second unloading turntable 81 is configured to rotate in a clockwise direction.

[0130] When the support cup 20 reaches the position corresponding to the second unloading turntable 81 under the transfer of the battery shell carrier 5, the gear mouth on the second unloading turntable 81 is clamped on the side of the support cup 20 facing the second unloading turntable 81. As the second unloading turntable 81 and the turret 2 continue to rotate, the support cup 20 disengages from the arc-shaped slot 5211 on the fixed seat 52 and is located between the second unloading turntable 81 and the second enclosure 82, so as to realize the unloading processing of the support cup 20 under the drive of the second unloading turntable 81.

[0131] Furthermore, the second unloading unit 8 also includes a discharge buffer line 83; the first end of the discharge buffer line 83 extends to the lower side of the second unloading turntable 81 and the second enclosure 82, and the second end of the discharge buffer line 83 extends to other workstations for battery processing.

[0132] It is understandable that the discharge buffer line 83 can adopt a chain plate conveyor, and the first end of the discharge buffer line 83 extends along the circumference of the second discharge turntable 81 and is located between the second discharge turntable 81 and the second enclosure 82.

[0133] The discharge buffer line 83 is used to receive multiple cups 20 output from the second unloading turntable 81, and can cache multiple cups 20 along its extension direction to meet the use requirements of the cups 20 by the collecting plate welding station, battery cell sealing welding station, flipping station and other stations.

[0134] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
