Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of battery, in particular to a laser dust removal device and a battery welding device. BACKGROUND

[0002] In the processing of lithium batteries, laser coding is generally performed on the parts of lithium batteries, such as cover plates, by a multi-station turntable. The turntable is provided with stations at a fixed position around the turntable. The cover plate is clamped on the turntable, and the cover plate is driven to rotate by the turntable to sequentially pass through each station, thereby completing the processing of the cover plate. In the laser coding process of the cover plate of the lithium battery, dust removal is a crucial process step.

[0003] In the related art, a station is generally provided for the dust removal process. The turntable stops at the dust removal station for dust suction, and then rotates to the next station after the dust suction is completed. However, the independent dust removal station increases the size of the turntable and the number of stations, resulting in an increase in the floor area occupied by the equipment. Moreover, the separation of the timing of coding and dust removal may cause the spread of processing dust. Alternatively, the dust removal function is integrated into the coding station. However, the dust removal mechanism needs to perform a long stroke movement to avoid the rotation of the turntable, which in turn prolongs the processing time of the coding station and reduces the overall production efficiency.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0024] In the related art, a dust removal process is generally provided with a separate station, and the turntable stops at the dust removal station for dust suction. After the dust suction is completed, the turntable rotates to the next station. However, the independent dust removal station increases the size of the turntable and the number of stations, resulting in an increase in the equipment floor area. Moreover, the timing separation of coding and dust removal may cause the risk of diffusion of processing dust. Alternatively, the dust removal function is integrated into the coding station. However, the dust removal mechanism needs to perform a long stroke movement to avoid the rotation of the turntable, which in turn prolongs the processing time of the coding station and reduces the overall production efficiency.

[0025] To solve the above problems, the embodiment of the present application provides a laser dust removal device, which can combine the dust removal mechanism and the turntable into one body. On the basis of not increasing the size of the turntable and the number of stations, the coding and dust removal are simultaneously performed, and the processing time of the single station is reduced.

[0026] The technical solutions of the embodiments of the present application are described in detail below with reference to the drawings.

[0027] Referring to Figure 1 and Figure 2 The embodiment of the present application provides a laser dust removal device, which includes a turntable 1, a clutch mechanism 3 and a dust removal mechanism 2. The turntable 1 is provided with a plurality of stations 10 along the circumference thereof. The clutch mechanism 3 is arranged on the turntable 1, and a dust removal passage 30 is formed in the clutch mechanism 3. The dust removal mechanism 2 includes a plurality of dust removal suction pipes 20 arranged along the circumference of the turntable 1. One end of at least one dust removal suction pipe 20 is connected to the clutch mechanism 3, and the other end faces the corresponding station. When the turntable 1 rotates, the clutch mechanism 3 is used to selectively connect at least one dust removal suction pipe 20 to the dust removal passage 30.

[0028] The laser dust removal device of the embodiment of the present application can include a rack for supporting the turntable 1. The turntable 1 can rotate around its own center.

[0029] The rotary table 1 is provided with a plurality of workstations 10 along the circumference thereof, for example, the rotary table 1 is provided with four workstations along the circumference thereof, and the four workstations can be respectively a feeding and scanning code workstation, a code marking workstation, a post-marking scanning code workstation and a discharging workstation. The feeding and scanning code device and the area corresponding to the rotary table 1 form the feeding and scanning code workstation, the code marking device and the area corresponding to the rotary table 1 form the code marking workstation, the post-marking scanning code device and the area corresponding to the rotary table 1 form the post-marking scanning code workstation, and the discharging device and the area corresponding to the rotary table 1 form the discharging workstation. Among them, dust removal operation needs to be carried out in the code marking workstation, and the code marking workstation is a set workstation. It should be noted that the set workstation can be designed as multiple according to production requirements. During operation, the workpiece is clamped from the feeding and scanning code position to the rotary table 1, and after the scanning code gun outside the rotary table 1 completes the scanning code operation on the workpiece, the rotary table 1 rotates by 90°, so that the workpiece rotates from the feeding and scanning code position to the code marking workstation and stops rotating. When the rotary table 1 rotates to the code marking workstation, the laser outside the rotary table 1 performs code marking operation on the workpiece, and the clutch mechanism 3 selectively connects the dust removal suction pipe 20 corresponding to the code marking workstation with the dust removal channel 30, and the other three workstations do not need dust removal, and the corresponding dust removal suction pipe 20 is not connected with the dust removal channel 30. Then the rotary table 1 continues to rotate, and the same operation is performed to complete the post-marking scanning code and cover plate discharging operations of the workpiece.

[0030] It should be understood that each of the above workstations does not change with the rotation of the rotary table 1.

[0031] The embodiment of the present application can selectively connect at least one dust removal suction pipe 20 with the dust removal channel 30 through the clutch mechanism 3 when the rotary table 1 rotates, which is equivalent to that the clutch mechanism 3 can selectively connect the dust removal suction pipe 20 corresponding to the workstations that need dust removal, such as the code marking workstation, with the dust removal channel 30, while the dust removal suction pipes 20 corresponding to the workstations that do not need dust removal are not connected with the dust removal channel 30, so that the dust removal mechanism integrated on the rotary table 1 can always connect the dust removal suction pipe 20 corresponding to the workstations that need dust removal, such as the code marking workstation, with the dust removal channel 30 every time the rotary table 1 rotates, which can realize code marking and dust removal at the same time without increasing the size of the rotary table and the number of workstations, and reduces the processing time of a single workstation.

[0032] As an optional embodiment, referring to Figure 3 , the clutch mechanism 3 includes a first part 31 and a second part 32 that can rotate relative to each other, the first part 31 is connected with a plurality of dust removal suction pipes 20, and the second part 32 is provided with a dust removal channel 30; and selectively connecting at least one dust removal suction pipe 20 with the dust removal channel 30 when the rotary table 1 rotates.

[0033] In the embodiments of the present application, the clutch mechanism 3 comprises a first component 31 and a second component 32 which are rotatable relative to each other. In an exemplary first mode, the first component 31 is rotatable with the rotating disc 1, and the second component 32 is stationary relative to the rotating disc 1. Alternatively, in a second mode, the second component 32 is rotatable with the rotating disc 1, and the first component 31 is stationary relative to the rotating disc 1.

[0034] In the first mode, the first component 31 (rotating member) is connected to a plurality of dust suction pipes 20 and rotates synchronously with the rotating disc 1. The second component 32 (stationary member) has a dust removal passage 30 formed therein and is stationary. In this mode, the suction pipe interfaces of the first component 31 are distributed along the circumference, and the inlets of the dust removal passage 30 of the second component 32 are located at fixed positions.

[0035] When the rotating disc 1 rotates, the first component 31 drives the dust suction pipes 20 to pass through the inlets of the dust removal passage 30 of the second component 32 in sequence. The communication between the dust suction pipes 20 and the dust removal passage 30 is selectively achieved only when at least one dust suction pipe 20 is rotated to align with at least one inlet of the dust removal passage 30 (other dust suction pipes 20 are in a disconnected state). In this mode, the second component 32 is stationary, and the dust removal passage 30 can be directly connected to an external dust removal device without the risk of hose entanglement.

[0036] In the second mode, the first component 31 (stationary member) is connected to a plurality of dust suction pipes 20. The second component 32 (rotating member) has a dust removal passage 30 formed therein and rotates synchronously with the rotating disc 1. In this mode, the inlets of the dust removal passage 30 are designed on the rotating path of the second component 32 and periodically align with the interfaces of the stationary dust suction pipes 20.

[0037] When the rotating disc 1 rotates, the inlets of the dust removal passage 30 of the second component 32 sweep through the dust suction pipes 20 of the first component 31 in sequence. The communication between the dust removal passage 30 and the dust suction pipes 20 is selectively achieved only when at least one inlet of the dust removal passage 30 is rotated to align with at least one dust suction pipe 20. In this mode, the stationary first component 31 can be designed to have the dust suction pipes arranged in a concentrated manner (e.g., radially), reducing the complexity of the rotating part.

[0038] As a preferred embodiment, referring to Figure 5 and Figure 6 , the first component 31 has a plurality of first connection interfaces 33 formed along the circumference thereof, each first connection interface 33 aligning with and communicating with at least one dust suction pipe 20. The second component 32 has at least one second connection interface 34 provided along the circumference thereof, the second connection interface 34 communicating with the dust removal passage 30. At least one dust suction pipe 20 is selectively aligned with and communicated with the second connection interface 34 when the rotating disc 1 rotates.

[0039] The first component 31 rotates with the rotating disc 1, and the plurality of first connecting ports 33 distributed circumferentially of the first component 31 sequentially pass through the fixed second connecting ports 34. The communication between the dust removal channel 30 and the dust removal suction pipe 20 is selectively realized only when at least one first connecting port 33 rotates to coincide with at least one second connecting port 34. In this mode, the rotating first connecting port 33 can quickly switch the suction pipe, which is suitable for high-frequency switching scenarios (such as high-speed rotating dust removal). Moreover, the fixed dust removal channel 30 can be directly hard-piped connected to an external system, without the risk of hose entanglement.

[0040] The second component 32 rotates with the rotating disc 1, and the second connecting ports 34 sequentially sweep through the fixed first connecting ports 33 of the first component 31. The corresponding dust removal suction pipe 20 is activated only when at least one second connecting port 34 is aligned with at least one first connecting port 33. In this mode, a plurality of non-adjacent suction pipes can be simultaneously communicated by designing the number and distribution of the second connecting ports 34 (such as symmetrical arrangement). Moreover, the suction pipes of the fixed first component 31 can be arranged in a concentrated manner to reduce the volume of the rotating part.

[0041] As a preferred embodiment, referring to Figure 3 , the first component 31 is connected with the rotating disc 1 and can drive a plurality of dust removal suction pipes 20 to rotate with the rotating disc 1; the second component 32 is fixedly arranged relative to the rotating disc 1, and at least one second connecting port 34 is arranged relative to a set station; and when the rotating disc 1 rotates, at least one second connecting port 34 corresponding to the set station is selectively aligned and communicated with at least one first connecting port 33.

[0042] The embodiments of the present application are exemplarily described by taking the feeding and scanning code station-encoding station-scanning code station after encoding-feeding station as an example.

[0043] In the working process, the dust removal channel 30 of the second component 32 is fixed relative to the rotating disc 1 and does not rotate, and can be connected to an external negative pressure air source. The second component 32 only opens one second connecting port 34 relative to the encoding station. The first component 31 opens four first connecting ports 33, each of which is connected with two dust removal suction pipes 20, and the first component 31 is fixed on the rotating disc 1 and can rotate with the rotating disc 1. Each time the rotation stops, a first connecting port 33 will rotate to the encoding station, the second connecting port 34 corresponding to the encoding station is aligned and communicated with the first connecting port 33 rotating to the encoding station, and a negative pressure dust removal effect is generated; while the other three first connecting ports 33 are not communicated with the second connecting ports 34, and no negative pressure dust removal effect is generated. Therefore, the effect of simultaneous encoding and dust removal of the encoding station at each rotation stop can be realized.

[0044] As a preferred embodiment, referring to Figure 3 , the first component 31 is coaxially arranged with the rotating disc 1, and the first component 31 is sleeved outside the second component 32.

[0045] The first component 31 is coaxially arranged with the rotary disc 1 and sleeved outside the second component 32 in the embodiment of the application, so that the space utilization can be improved, the coaxial sleeving structure maximally saves the radial installation space, and the circumferential uniform arrangement of the dust removal suction pipes 20 is facilitated, and the external rotary component is more conducive to heat dissipation and maintenance.

[0046] As a preferred embodiment, a radial sealing ring is arranged on the rotary contact surface between the first component 31 and the second component 32. The radial sealing ring is more suitable for the rotary working condition and improves the stability of dynamic rotation.

[0047] As a preferred embodiment, referring to Figure 4 , Figure 6 and Figure 7 , the rotary disc 1 is provided with a mounting hole 11, and the second component 32 is provided with a notch 320 at one end close to the rotary disc 1 in the circumferential direction; the clutch mechanism 3 further comprises a locking piece 35, one end of the locking piece 35 penetrates through the mounting hole 11 and is limitedly matched with the notch 320, so that the second component 32 is fixed relative to the rotary disc 1.

[0048] The high-precision positioning and locking of the notch 320 and the locking piece 35 in the circumferential direction are facilitated.

[0049] As a preferred embodiment, the first component 31 is fixedly arranged relative to the rotary disc 1, and at least one first connecting port 33 is arranged relative to a set station; the second component 32 is connected with the rotary disc 1 and can rotate with the rotary disc 1; and when the rotary disc 1 rotates, the at least one first connecting port 33 corresponding to the set station is selectively aligned and communicated with the at least one second connecting port 34.

[0050] The embodiment of the application is exemplarily described by taking the feeding and code scanning station, the code marking station, the code marking and code scanning station after marking and the discharging station as examples.

[0051] During the working process, the first component 31 is provided with one first connecting port 33 relative to the code marking station, one first connecting port 33 connects two dust removal suction pipes 20, and the first component 31 is fixed relative to the rotary disc 1 and does not rotate. The second component 32 is fixed on the rotary disc 1 and can rotate with the rotary disc 1. The second component 32 is provided with four second connecting ports 34. Each time the rotation stops, one second connecting port 34 rotates to the code marking station, the first connecting port 33 corresponding to the code marking station is aligned and communicated with the second connecting port 34 rotating to the code marking station, and the negative pressure dust removal effect is generated; and the other three second connecting ports 34 are not communicated with the first connecting port 33, and the negative pressure dust removal effect is not generated. Therefore, the code marking and dust removal effects of the code marking station at each time of rotation stop can be realized.

[0052] As an optional embodiment, referring to Figure 1 and Figure 2, the dust suction pipe 20 away from the clutch mechanism 3 one end is equipped with dust suction pipe assembly 21, dust suction pipe assembly 21 includes along the radial direction of the turntable 1 is equipped with dust suction pipe 210, and the dust suction pipe 210 is vertically connected with dust suction head 211, dust suction head 211 and dust suction pipe 210 together form the bearing space 22 for carrying workpiece.

[0053] The radial dust suction pipe 210 forms the main airflow channel in the embodiment of the application, and the vertical dust suction head 211 generates vortex effect to increase dust capture efficiency. The L-shaped structure formed by the dust suction head 211 and the dust suction pipe 210 can simultaneously realize workpiece bearing positioning and dust splashing prevention.

[0054] As an optional embodiment, referring to Figure 1 、 Figure 3 and Figure 4 , the dust removal mechanism 2 further comprises a negative pressure pipe 23, which is in communication with the dust removal channel 30 and is used to provide negative pressure to the dust removal channel 30. High-efficiency dust collection can be achieved.

[0055] Corresponding to the foregoing application function implementation device embodiment, the application further provides a battery welding device and a corresponding embodiment.

[0056] Referring to Figure 8 , the embodiment of the application further provides a battery welding device, which comprises the foregoing laser dust removal device and a plurality of welding devices arranged along the circumference of the turntable 1; the area corresponding to the plurality of welding devices of the turntable 1 forms a plurality of workstations 10.

[0057] In the embodiment of the application, taking the four workstations arranged along the circumference of the turntable 1 as an example, the four workstations can be a feeding and code scanning workstation, a code marking workstation, a code scanning workstation after marking, and a discharging workstation. The area corresponding to the feeding and code scanning device of the turntable 1 forms the feeding and code scanning workstation, the area corresponding to the code marking device of the turntable 1 forms the code marking workstation, the area corresponding to the code scanning device after marking of the turntable 1 forms the code scanning workstation after marking, and the area corresponding to the discharging device of the turntable 1 forms the discharging workstation. Among them, dust removal operation needs to be performed at the code marking workstation, and the code marking workstation is a set workstation. It should be noted that a plurality of set workstations can be designed according to production requirements. During operation, the workpiece is clamped from the feeding and code scanning position to the turntable 1, and after the code scanning gun outside the turntable 1 completes the code scanning operation on the workpiece, the turntable 1 rotates by 90°, so that the workpiece rotates from the feeding and code scanning position to the code marking workstation and stops rotating. When the turntable 1 rotates to the code marking workstation, the laser outside the turntable 1 performs code marking operation on the workpiece, and the clutch mechanism 3 selectively connects the dust suction pipe 20 corresponding to the code marking workstation with the dust removal channel 30, and the dust suction pipe 20 corresponding to the other three workstations is not connected with the dust removal channel 30. Then the turntable 1 continues to rotate, and the same operation is performed to complete the code scanning after marking and the cover plate discharging of the workpiece.
