[0002] During battery manufacturing, the cells undergo a series of processes, including mechanical / ultrasonic flattening, encapsulation, casing, current collector welding, and sealing welding, before being assembled into a battery.

[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] The following is combined Figures 1-6The invention provides a detailed description of the battery casing dust removal mechanism and turret-type battery casing dust removal equipment through specific embodiments and application scenarios.

[0042] In the first aspect, such as Figure 1 and Figure 2 As shown, the present invention provides a battery casing dust removal mechanism 1, including: a fixed frame 11, a lifting frame 12, an elastic element 13 and a dust removal element 14;

[0043] The fixed frame 11 is configured to be located on one side of the turret 2, and the lifting frame 12 is movably located on the fixed frame 11 in the vertical direction; the dust removal component 14 includes a dust removal head 141, which is located on the lifting frame 12, and the elastic member 13 is located between the fixed frame 11 and the lifting frame 12.

[0044] The lifting frame 12 is provided with a first rolling element 120, which is configured to roll in contact with the first cam rail 3 on the turret 2; the lifting frame 12 is used to move up and down relative to the fixed frame 11 between a first height and a second height under the elastic force of the elastic element 13 and the lifting guidance of the first cam rail 3.

[0045] When the lifting frame 12 is at its first height, the dust removal head 141 is inserted into the battery casing 10 on the turret 2 to remove dust from the battery casing 10; when the lifting frame 12 is at its second height, the dust removal head 141 is separated from the battery casing 10.

[0046] Understandably, 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, which 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.

[0047] The turret 2 can drive the first cam track 3 to rotate around its axis of rotation. The first rolling element 120 can only move up and down vertically 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 distributed battery casing 10 to rotate, and the first rolling element 120 rolls along the extension direction of the first cam track 3 during this process.

[0048] Specifically, the elastic element 13 is used to apply an elastic tension to the lifting frame 12 vertically downwards; the first cam track 3 is used to drive the first rolling element 120 to raise the lifting frame 12, 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 casing 10 from bottom to top to remove dust from the battery casing 10. During the process of the lifting frame 12 rising from the second height to the first height, the elastic element 13 is gradually stretched and switches from the initial state to the stretched state, storing a large amount of elastic potential energy.

[0049] At the same time, the first cam track 3 can also guide the first rolling element 120 to descend. During the descent of the first rolling element 120, the elastic element 13 will return from the stretched state to the initial state, thereby driving the lifting frame 12 to descend, and then the lifting frame 12 will drive the dust removal head 141 to separate from the battery case 10.

[0050] Optionally, the first rolling element 120 may be a roller or a rolling bearing, and the first rolling element 120 is rotatably disposed on the lifting frame 12 about a horizontal axis.

[0051] Optionally, the elastic element 13 can be a spring, which is vertically distributed, with its upper end connected to the bottom end of the lifting frame 12 and its lower end connected to the bottom end of the fixed frame 11.

[0052] Meanwhile, multiple elastic elements 13 can be provided, and multiple elastic elements 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, so as to separate the dust removal head 141 from the battery case 10.

[0053] Optionally, the dust removal head 141 can be a brush, a blower, 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 housing 10 to ensure that the dust removal head 141 can be inserted and withdrawn relative to the battery housing 10 in the vertical direction during the rotation of the battery housing 10 with the turret 2.

[0054] As can be seen from the above, the battery casing dust removal mechanism 1, through the configuration of a fixed frame 11, a lifting frame 12, an elastic element 13, and a dust removal component 14, can achieve the lifting frame 12 driving the dust removal component 14 to move up and down relative to the fixed frame 11 with the cooperation of the elastic element 13 and the first cam track 3 on the turret 2. This ensures that the dust removal head 141 can complete the insertion and extraction actions in the vertical direction relative to the battery casing 10 as the battery casing 10 rotates with the turret 2, thereby achieving dust removal of the inner wall of the battery casing 10. This design requires no manual intervention; the lifting and lowering control of the dust removal head 141 can be achieved through simple mechanical linkage, enabling convenient dust removal of vertically distributed battery casings 10 and ensuring efficient dust removal of the battery casing 10.

[0055] Meanwhile, compared to the horizontal dust removal design of the battery casing 10, the dust removal design of the present invention not only simplifies the dust removal control process, but also helps to reduce the space occupied.

[0056] In some embodiments, such as Figure 1 and Figure 6 As shown, the dust collector head 141 has an inner cavity and an air hole communicating with the inner cavity. The air hole is located on the surface of the dust collector head 141, and the inner cavity is configured to communicate with a blower and / or a negative pressure dust collection device.

[0057] Specifically, the dust removal head 141 is cylindrical, and the battery casing 10 is open at the bottom. The bottom end of the dust removal head 141 is connected to the lifting frame 12, so that it can be inserted vertically from bottom to top into the battery casing 10 under the action of the lifting frame 12; after completing the dust removal operation on the battery casing 10, the dust removal head 141 can also be driven by the lifting frame 12 to leave the battery casing 10 from the bottom side.

[0058] Meanwhile, the top and peripheral walls of the dust collector head 141 are provided with multiple air holes. When the inner cavity is connected to the blower, the compressed gas input by the blower can be distributed to each air hole through the inner cavity, and then sprayed onto the inner wall of the battery casing 10 through the air holes to remove dust from the inner wall of the battery casing 10; when the inner cavity is connected to the negative pressure dust collection device, under the drive of negative pressure, the air and dust in the battery casing 10 can enter the negative pressure dust collection device in sequence through the air holes and the inner cavity.

[0059] In some embodiments, such as Figure 2 and Figure 6 As shown, the dust removal component 14 also includes: a first vent connector 142 and a second vent connector 143; the inner cavity is connected to the first vent connector 142 and the second vent connector 143 respectively; the first vent connector 142 is configured to be connected to a blower; and the second vent connector 143 is configured to be connected to a negative pressure dust collection device.

[0060] Furthermore, in order to automatically perform dust removal on the battery casing 10 and ensure the dust removal effect, the battery casing dust removal mechanism 1 is also equipped with a detection element 15. The detection element 15 is connected to the control module, and the control module is electrically connected to the first vent connector 142 and the second vent connector 143 respectively.

[0061] The detection element 15 is used to detect the lifting height of the lifting frame 12; the control module is used to control the first vent connector 142 and the second vent connector 143 to connect sequentially when the detection element 15 detects that the lifting frame 12 is at the first height.

[0062] Specifically, the detection element 15 can be a photoelectric switch and is mounted on the fixed frame 11; the lifting frame 12 is equipped with a sensing plate. When the sensing plate rises with the lifting frame 12 and reaches a position that can trigger the photoelectric switch, the lifting frame 12 is at the first height. At this time, the control module controls the first ventilation connector 142 to be turned on according to the feedback signal, so that the dust removal head 141 blows air into the battery case 10, and sets the blowing time of the dust removal head 141.

[0063] When the blowing time reaches the preset value, the control module controls the first air connector 142 to close and the second air connector 143 to open, so that the negative pressure dust collection equipment can collect dust in the battery case 10 through the dust collection head 141, thereby completing the automatic dust removal operation of the battery case 10.

[0064] The first vent connector 142 and the second vent connector 143 are both equipped with solenoid valves that can be opened and closed in response to the control module. The control module can be a PLC controller or a microcontroller known in the art.

[0065] In some embodiments, such as Figure 1 As shown, the lifting frame 12 includes a lifting seat 121, a mounting platform 122, and a suspension 123; the lifting seat 121 is located on the side of the mounting platform 122 away from the turret 2 and is movably mounted on the fixed frame 11 in the vertical direction; the suspension 123 is located on the side of the mounting platform 122 facing the turret 2 and is connected to the first rolling element 120; the dust removal head 141 is located on the mounting platform 122.

[0066] Understandably, the lifting seat 121 and the suspension 123 are respectively vertically arranged on the lower side of the mounting platform 122 so that the upper side of the mounting platform 122 is exposed. The dust removal head 141 is arranged on the mounting platform 122 in a vertically distributed manner. This design not only facilitates the rolling cooperation between the first rolling element 120 and the first cam track 3 on the turret 2 without interference between them, but also facilitates the mounting platform 122 to support the dust removal head 141 to be smoothly inserted into or pulled out of the battery case 10.

[0067] The lifting base 121 and the lifting frame 12 are provided with the sliding guide structure shown in the above embodiment. The sensing sheet can be set on the lifting base 121 to trigger the photoelectric switch on the fixed frame 11.

[0068] In the second aspect, such as Figure 3 As shown, the present invention also provides a turret-type battery casing dust removal device, comprising: a turret 2, a battery casing carrier 5, and a battery casing dust removal mechanism 1 as described in any of the above.

[0069] The battery housing carrier 5 is used to carry vertically distributed battery housings 10; the battery housing carrier 5 is located on the periphery of the turret 2 and can rotate under the drive of the turret 2.

[0070] The first cam track 3 is connected to the turret 2 and makes rolling contact with the first rolling element 120 on the battery casing dust removal mechanism 1.

[0071] Specifically, the turret 2 includes a turret body 21 and a rotary drive mechanism 22. The rotary drive mechanism 22 and the turret body 21 are dynamically coupled to drive the turret body 21 to rotate around its central axis. The first cam track 3 is connected to the lower end of the turret body 21 and extends along the circumference of the turret body 21 to rotate with the turret body 21.

[0072] Meanwhile, the battery housing carrier 5 is detachably installed on the periphery of the tower body 21. Multiple battery housing carriers 5 can be installed, and multiple battery housing carriers 5 are arranged sequentially along the circumference of the turret 2. This design can complete the dust removal operation of multiple battery housings 10 at one time during the rotation of the turret 2, which not only has high dust removal efficiency, but also occupies little space.

[0073] Since the turret-type battery casing dust removal device includes a battery casing dust removal mechanism 1, and the specific structure of the battery casing dust removal mechanism 1 is as described in the above embodiments, the turret-type battery casing dust removal device shown in this embodiment includes all the technical solutions of the above embodiments. Therefore, it has at least all the beneficial effects obtained by all the technical solutions of the above embodiments, which will not be described in detail here.

[0074] In some embodiments, such as Figure 3 and Figure 4 As shown, the first cam track 3 includes multiple upper convex sections 31 and multiple lower concave sections 32; the multiple upper convex sections 31 and multiple lower concave sections 32 are connected alternately in sequence along the circumference of the turret 2.

[0075] exist Figure 4 The rotation direction of the turret 2 is indicated by an arc-shaped arrow. Since the battery casing dust removal mechanism 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 sequentially roll into contact with the first rolling member 120, and this cycle repeats. When the first rolling member 120 moves along the upper convex section 31, the upper convex section 31 drives the first rolling member 120 to raise the lifting frame 12; when the first rolling member 120 moves along the lower concave section 32, the elastic member 13 drives the lifting frame 12 to descend.

[0076] Specifically, since multiple upper convex sections 31 and multiple lower concave sections 32 are alternately connected along the circumference of the turret 2, during the rolling process of the first rolling element 120 along the first cam track 3, the first rolling element 120 will pass through the alternately arranged upper convex sections 31 and lower concave sections 32 in sequence. Thus, based on the mutual cooperation between the first cam track 3 and the elastic element 13, the lifting frame 12 can reciprocate to perform lifting and lowering movements.

[0077] Thus, when each battery casing 10 is evenly distributed around 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 reciprocate up and down at a set position by the lifting frame 12, thereby realizing the dust removal operation of each battery casing 10 in sequence.

[0078] Furthermore, in order to ensure that the dust removal head 141 can reciprocate vertically in a stable manner, both the upper convex section 31 and the lower concave section 32 are arc-shaped (e.g., circular arc), so that the first cam track 3 extends along a sinusoidal trajectory in the circumference of the turret 2.

[0079] In some embodiments, such as Figure 4 and Figure 6 As shown, the battery housing carrier 5 includes an adapter frame 51 and a fixing seat 52; the adapter frame 51 is connected to the turret 2, and the fixing seat 52 is located on the adapter frame 51; the fixing seat 52 is used to fix the cup 20, and the cup 20 supports the battery housing 10; the dust removal head 141 can be inserted through the cup 20 and extend into the battery housing 10.

[0080] Specifically, the adapter 51 has a first sidewall and a second sidewall facing away from each other. The first sidewall is connected to the turret 2, and the second sidewall is connected to the fixing seat 52. The fixing seat 52 is used to fix the cups 20 distributed vertically.

[0081] like Figure 6 As shown, the cup holder 20 includes a cup body 201 and a magnet 202; the fixing base 52 is connected to part of the peripheral wall of the cup body 201. The cup body 201 is cylindrical, and the magnet 202 is located inside the cup body 201. A retaining ring is provided on the inner wall of the cup body 201. The retaining ring is coaxially arranged with the cup body 201 and located near the bottom end of the cup body 201. The battery case 10 is inserted into the cup holder 20, and the retaining ring supports the bottom end of the battery case 10. This design allows the cup holder 20 to support the battery case 10 while also facilitating the dust removal head 141 to pass through the retaining ring first and then insert into the battery case 10 for dust removal.

[0082] Furthermore, the bottom end of the cup body 201 is provided with an annular groove 203, which extends circumferentially along the cup body 201. The annular groove 203 is used to install an RFID tag. The RFID tag can be read by a reader to bind information to the cup holder 20 and the battery case 10 it supports, and also facilitates the tracking of the position of the cup holder 20.

[0083] In some embodiments, in order to facilitate the fixing of the cup holder 20, the fixing base 52 can be configured as a magnetic card holder 521, which is used to be locked onto at least part of the peripheral wall of the cup holder 20 and magnetically attracted to the cup holder 20.

[0084] Understandably, the magnetic card holder 521 is provided with a snap-fit ​​structure, which can snap-fit ​​with the peripheral wall of the cup 20 based on the snap-fit ​​structure; at the same time, the magnetic card holder 521 can also be provided with a magnetic suction component, which can attract the magnet 202 inside the cup 20 to ensure that the cup 20 is reliably snapped in the snap-fit ​​structure.

[0085] The magnetic components and the magnets 202 inside the cup holder 20 can both be neodymium iron boron magnets to ensure the magnetic attraction effect between the magnetic card holder 521 and the cup holder 20.

[0086] Specifically, the magnetic card holder 521 has an arc-shaped card groove 5211 on the side opposite to the turret 2, and an arc-shaped baffle 5212 is provided at the upper end of the magnetic card holder 521. The arc-shaped baffle 5212 is located on the groove wall of the arc-shaped card groove 5211 and extends along the extension direction of the arc-shaped card groove 5211. The groove wall of the arc-shaped card groove 5211 is used to fit against the peripheral wall of the cup holder 20, and the arc-shaped baffle 5212 is used to stop on the top surface of the cup holder 20.

[0087] Understandably, the groove wall of the arc-shaped groove 5211 extends circumferentially relative to the central axis of the cup 20 to ensure that the groove wall of the arc-shaped groove 5211 can fit against the peripheral wall of the cup 20.

[0088] Meanwhile, by setting an arc-shaped stop 5212 on the top surface of the stop cup 20, the cup 20 can be positioned vertically, effectively preventing the cup 20 from moving upward when touched by the lifting frame 12 during the dust removal process of the battery case 10.

[0089] In some embodiments, such as Figure 5 As shown, the fixing base 52 also includes a limiting bracket 522, which is disposed on the upper side of the magnetic bracket 521. The limiting bracket 522 has an arc-shaped notch on the side away from the turret 2. The arc-shaped notch can fit against the peripheral wall of the battery case 10. The limiting bracket 522 can also be configured to magnetically attract the battery case 10 to ensure that the battery case 10 is reliably placed in the cup 20 during dust removal operations.

[0090] Furthermore, such as Figure 3 As shown, the battery case carrier 5 also includes a transfer mechanism 53; the transfer mechanism 53 and the fixed base 52 are respectively disposed on the adapter 51 and are arranged in a vertically opposite manner; the transfer mechanism 53 is used to control the separation of the battery case 10 from the cup 20; wherein, the dust removal head 141 can pass through the cup 20 and extend into the battery case 10.

[0091] Understandably, the transfer mechanism 53 and the fixed base 52 are respectively located on the side of the adapter 51 away from the turret 2. The transfer mechanism 53 can be connected to the battery case 10 and control the battery case 10 to move upward so as to separate the battery case 10 from the cup 20.

[0092] The transfer mechanism 53 can be a robotic arm, gripper, etc., and there are no specific limitations on it.

[0093] In some embodiments, such as Figure 4As shown, the transfer mechanism 53 includes a sliding frame 531, a gripper 532, and a second rolling element 533. The sliding frame 531 is movably mounted on the adapter 51 in the vertical direction. The gripper 532 and the second rolling element 533 are respectively mounted on the sliding frame 531. The gripper 532 is used to hold the battery case 10. The turret 2 is provided with a fixed second cam track 4, which extends circumferentially along the turret 2. The second rolling element 533 rolls in contact with the second cam track 4 and can drive the sliding frame 531 to move the gripper 532 up and down under the guidance of the second cam track 4.

[0094] Understandably, a sliding guide structure is provided between the sliding frame 531 and the adapter frame 51. The sliding guide structure includes a slide rail and a slide groove, which 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.

[0095] The second rolling element 533 is located at the upper end of the sliding frame 531 and can roll along the extension direction of the second cam track 4; the second rolling element 533 can be a roller or a rolling bearing.

[0096] The gripper 532 can be a pneumatic gripper or an electric gripper. The gripping end of the gripper 532 is set vertically downward and corresponds to the upper end of the battery case 10.

[0097] In some embodiments, such 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 battery casing dust removal mechanism 1 is arranged.

[0098] When the second rolling element 533 moves along the lower convex section 41, the gripper 532 is at a height position that can grip the battery case 10; when the second rolling element 533 moves along the upper concave section 42, the gripper 532 grips the battery case 10 and separates the battery case 10 from the cup 20.

[0099] Understandably, both the lower convex section 41 and the upper concave section 42 have horizontal segments. When the second rolling element 533 moves along the horizontal segment of the lower convex section 41, the gripper 532 is at a third height, with the gripping ends of the gripper 532 located on opposite sides of the battery casing 10. When the second rolling element 533 moves from the horizontal segment of the lower convex section 41 toward the upper concave section 42, the gripper 532 clamps the battery casing 10 and moves it upwards while holding it in place. When the second rolling element 533 moves to the horizontal segment of the upper concave section 42, the gripper 532 is at a fourth height, thus separating the battery casing 10 from the cup 20.

[0100] In some embodiments, multiple battery casing dust removal mechanisms 1 are provided, and the multiple battery casing dust removal mechanisms 1 are arranged sequentially along the circumference of the turret 2.

[0101] Understandably, when the second cam track 4 includes a lower convex section 41 and an upper concave section 42, the multiple battery casing dust removal mechanisms 1 are arranged opposite to the horizontal segments of the lower convex section 41.

[0102] Since each battery casing dust removal mechanism 1 can perform a dust removal process on the battery casing 10 once, when the battery casing 10 rotates circumferentially under the drive of the turret 2, multiple battery casing dust removal mechanisms 1 can repeatedly perform dust removal processes on the same battery casing 10 to ensure the dust removal effect on the battery casing 10.

[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.
