Description

Technical Field

[0001] The present invention relates to the technical field of laser slicing of electrode sheets, and specifically to a laser slicing device for lithium battery electrode sheets after coating. Background Art

[0002] The lithium battery electrode is a coating composed of particles, which is uniformly coated on a metal current collector. The lithium-ion battery electrode sheet coating can be regarded as a composite material, mainly composed of an active material phase in which active material particles, a conductive agent, and a binder are mixed with each other and pores filled with an electrolyte.

[0003] In battery manufacturing, laser technology can be used for electrode sheet slicing, three-dimensional microstructure processing of electrodes, tab slicing, aluminum-plastic film slicing, welding, and marking, etc. Laser processing technology is used for slicing, annealing, structuring, and 3D printing of lithium-ion battery electrodes, which can reduce manufacturing costs and improve the electrochemical performance and service life of lithium-ion batteries.

[0004] The patent document with the publication number CN202934243U, a laser slicing machine for electrode sheet coating and blanking, sends the electrode sheet flat to the adsorption bottom plate of the adsorption table device through a sheet storage system. The laser knife of the laser slicing device will slice at a constant speed through a motor drive device. After slicing, the dust collection device is started to suck up the waste and dust after slicing. The adsorption device is started through the drive device, reaches the position of the adsorption table, and the push cylinder pushes the movable connecting rod to grab the cut electrode sheet blank and send it to the next process for circulation. It realizes the automation of the equipment, greatly improves the production efficiency, is suitable for popularization and application, and has a simple structure and convenient operation.

[0005] However, in the process of implementing the above technical solution, it is found that the above technical solution has the following technical problems: After the laser slicing machine for electrode sheet coating and blanking completes the slicing work of the battery sheet, it uses a dust collection device to suck out waste and dust, and grabs the cut electrode sheet blank with the help of an adsorption device, which can realize the automation of product production. However, in the actual application process, the method of slicing, dust collection, and grabbing and taking materials in sequence takes a relatively long time in the process of slicing the electrode sheet, which is not conducive to maximizing the production efficiency in the automated slicing process of the electrode sheet. Summary of the Invention

[0006] In order to overcome the deficiencies of the existing laser slicing machine for electrode sheet coating and blanking. During the actual application process, the methods of slicing, dust suction, and grasping and feeding are carried out successively. In the process of slicing the electrode sheet, the overall time consumption is relatively long, which is not conducive to maximizing the production efficiency in the automated slicing process of the electrode sheet. The embodiment of the present application provides a laser slicing device for a lithium battery electrode sheet after coating. When the processing table structure is driven by the lead screw assembly A to make a reciprocating motion inside the gantry, on the one hand, one side of the ejector rod is blocked by one end of the pin key A to lift the push plate, and the push plate rotates around the shaft rod, which is beneficial to leaving a space for the to-be-processed electrode sheet to pass through on the surface of the push plate and the processing table board. On the other hand, one end of the ejector rod is blocked by one side of the push plate, driving the shaft column to rotate inside the column sleeve to tighten the torsion spring. When the push plate crosses one end of the ejector rod, it can move from the top of the processing table board to the top of the receiving table board to ensure the transfer of the processed electrode sheet during the blanking process of the electrode sheet and the removal of the processed electrode sheet during the processing of the electrode sheet, which is beneficial to shortening the waiting time and improving the processing efficiency.

[0007] The technical solution adopted by the embodiment of the present application to solve its technical problems is: A laser slicing device for a lithium battery electrode sheet after coating, including a laser slicing device main body, a processing table structure, and a dust suction structure. The processing table structure is arranged at the bottom of the laser slicing device main body; The dust suction structure is arranged on one side of the processing table structure; A bearing chassis is arranged at the bottom of the processing table structure. The center of the top of the bearing chassis is connected with a gantry in an assembled manner. The inner side of the top of the gantry is provided with a device support. The inner side of the bottom of the gantry is provided with a transfer structure; the processing table structure includes a receiving table board and a processing table board. The bottom of the receiving table board is hinged to a support plate. An electric push rod is hinged between the inside of the support plate and the bottom of one end of the receiving table board. Among them, the lithium battery electrode sheet is sliced and processed by the laser slicing device main body on the top of the processing table board. When the processing table structure moves to one side of the gantry, the sliced electrode sheet is transferred to the top of the receiving table board by the transfer structure, and then the electric push rod controls the receiving table board to discharge to one side of the dust suction structure, and the dust suction structure synchronously removes the dust on the electrode sheet.

[0008] In a possible implementation manner, the top of the bearing chassis drives the processing table structure to make a reciprocating motion from front to back at the bottom of the laser slicing device main body through an assembled lead screw assembly A. The top of the gantry drives the device support to make a reciprocating motion from one side to the other side inside the gantry through an assembled lead screw assembly B. The inside of the device support drives the laser slicing device main body to make a reciprocating motion from top to bottom at the device support through an assembled lead screw assembly C.

[0009] In a possible implementation, a waste receiving hopper is provided inside one end of the support plate. Bar-shaped grooves are machined at both corners at the top of one end of the waste receiving hopper. Pin blocks are pinned at both corners of one end of the support plate; one end of the pin block extends into the inside of the bar-shaped groove, and the waste receiving hopper is received at the bottom of one end of the support plate.

[0010] In a possible implementation, two multi-stage telescopic tubes are provided at the inner wall of the bottom of one end of the waste receiving hopper. Both of the two multi-stage telescopic tubes are composed of a plurality of square tubes sleeved step by step; the outermost one of the plurality of square tubes is hinged to one end of the electric push rod, and the innermost one of the plurality of square tubes is fixed to the inner wall of the bottom of one end of the waste receiving hopper. When the electric push rod controls the receiving table board to rotate around its hinge point with the support plate, with the cooperation of the multi-stage telescopic tube and the pin block, the waste receiving hopper is pushed to slide out to one side at the bottom of the support plate.

[0011] In a possible implementation, the dust suction structure includes a dust suction hood. The cross-section of the dust suction hood is U-shaped. A plurality of small holes for dust suction are machined on the inner wall of the dust suction hood. A dust suction pipe communicated with the plurality of small holes is assembled and connected to the outer wall of the dust suction hood. One end of the dust suction pipe is assembled and connected to a dust collector body; when the receiving table board tilts during rotation around its hinge with the support plate, large-volume electrode sheet waste slides from the surface of the receiving table board into the inside of the waste receiving hopper, and the electrode sheet is adsorbed by the dust suction hood to remove dust.

[0012] In a possible implementation, two symmetric angle blocks are assembled and connected to the top of one corner of the bearing chassis. A material receiving trough frame is assembled and connected between the two angle blocks. A dust suction support bracket is assembled and connected to the top of the two angle blocks. Two angle frames are assembled and connected to the top of the dust suction support bracket. A proximity switch is assembled and connected to the bottom on one side of the dust suction support bracket; Wherein, one side of the two angle frames is assembled and fixed to the outer wall of the dust suction hood. When the waste receiving hopper extends out from the bottom of one side of the support plate and approaches the proximity switch, the proximity switch turns on the internal circuit of the dust collector body, so that the dust collector body sucks the electrode sheet and dust through the dust suction pipe and the dust suction hood.

[0013] In a possible implementation, the transfer structure includes a push plate. Shaft rods are integrally formed at both ends of the push plate. A bearing is in interference fit with the outside of one end of the shaft rod. A shaft sleeve is in interference fit with the outside of the bearing. A seat frame is machined at one end of the shaft sleeve; the seat frame is assembled between both sides of the gantry. When the processing table structure moves inside the gantry, one side of the push plate is used to push the electrode sheet to move from the top of the processing table board to the top of the receiving table board.

[0014] In a possible implementation, the processing platen is made of multiple aluminum alloy profiles formed into a plate shape. The lithium battery electrode sheet is supported on the top of the processing platen for processing, and the waste material cut from the electrode sheet falls into the trough of the aluminum alloy profile.

[0015] In a possible implementation, a bushing is inserted into the inside of one end of an aluminum alloy profile at the center of the processing platen. Three keyways B and one keyway A are machined on the outer wall of one end of the bushing. A shaft column is rotatably connected to the inside of one end of the bushing. A push rod perpendicular to the axis is machined on the top of the shaft column; the bushing is keyed to the inside of one end of the aluminum alloy profile through three keyways B and one keyway A; the push rod is vertically upward. When the processing table structure is driven by the lead screw assembly A to move from one side to the other side inside the gantry, one end of the push rod jacks up the push plate, causing it to rotate around the shaft rod and straddle the electrode sheet to be processed on the top of the processing platen.

[0016] In a possible implementation, a support rod is integrally formed at one end of the shaft column, and a torsion spring is sleeved outside the support rod; both ends of the torsion spring are respectively fixed to the inside of the bushing and the support rod, and one end of the keyway A extends to one side of the shaft column to prevent the push rod from driving the shaft column to rotate inside the bushing under the action of the torsion spring.

[0017] The beneficial effects of this application are as follows: First, in this solution, the receiving platen is controlled by an electric push rod to rotate, so that the electrode sheet slides down along the inclined plane to one side of the dust suction hood, and at the same time, the waste material receiving hopper is pushed to slide out to one side at the bottom of the support plate. By means of the waste material receiving hopper extending close to the proximity switch, the proximity switch is turned on to connect the internal circuit of the vacuum cleaner body, so that the vacuum cleaner body can suck the electrode sheet and dust through the suction pipe and the dust suction hood. When the electric push rod resets and drives the waste material receiving hopper away from the proximity switch by means of the multi-stage telescopic pipe, the vacuum cleaner body is powered off, which is convenient for the electrode sheet adsorbed to the inside of the dust suction hood to fall to the inside of the material receiving trough rack under the influence of its own gravity, which is beneficial to combining the unloading and dust removal operations into the same operation step and shortening the processing time; Second, in this solution, when the processing table structure is driven by the lead screw assembly A to reciprocate inside the gantry, on the one hand, one side of the push rod is blocked by one end of the keyway A to jack up the push plate, causing the push plate to rotate around the shaft rod, which is beneficial to leaving a space for the electrode sheet to be processed to pass through on the surface of the push plate and the processing platen. On the other hand, one end of the push rod is blocked by one side of the push plate, driving the shaft column to rotate inside the bushing to twist the torsion spring. When the push plate straddles one end of the push rod, it can move from the top of the processing platen to the top of the receiving platen to ensure the transfer of the processed electrode sheet during the blanking process of the electrode sheet and the removal of the processed electrode sheet during the processing of the electrode sheet, which is beneficial to shortening the waiting time and improving the processing efficiency.

[0020] The technical solutions in the embodiments of the present application are to solve the problems in the above background technology, and the general idea is as follows: Embodiment 1: This embodiment introduces the specific structure of a laser slicing device for a lithium battery electrode sheet after coating. Specifically, refer to Figures 1 - 6 As shown in the figure, it includes a laser slicing device main body 10, a processing table structure 9 arranged at the bottom of the laser slicing device main body 10, and a dust suction structure 8 arranged on one side of the processing table structure 9. A bearing chassis 1 is arranged at the bottom of the processing table structure 9. A gantry 2 is assembled and connected at the center of the top of the bearing chassis 1. A device support 6 is arranged inside the top of the gantry 2, and a transfer structure 7 is arranged inside the bottom of the gantry 2; Among them, the top of the bearing chassis 1 drives the processing table structure 9 to make a reciprocating motion from front to back at the bottom of the laser slicing device main body 10 through an assembly screw rod assembly A3. The top of the gantry 2 drives the device support 6 to make a reciprocating motion from one side to the other side inside the gantry 2 through an assembly screw rod assembly B4, and the inside of the device support 6 drives the laser slicing device main body 10 to make a reciprocating motion from top to bottom at the device support 6 through an assembly screw rod assembly C5 (the screw rod assembly is a technical application in the prior art of laser slicing of lithium battery electrode sheets and will not be elaborated); As Figures 2 - 6 shown, the processing table structure 9 includes a receiving table board 901 and a processing table board 902. The bottom of the receiving table board 901 is hinged to a support plate 904, and an electric push rod 905 is hinged between the inside of the support plate 904 and the bottom of one end of the receiving table board 901; A waste receiving hopper 903 is arranged inside one end of the support plate 904. Strip-shaped grooves 11 are processed at both corners at the top of one end of the waste receiving hopper 903, and pin blocks 907 are pin-connected at both corners of one end of the support plate 904; Among them, by placing the lithium battery electrode sheet on the top of the processing table board 902, the laser slicing device main body 10 can perform slicing processing on it based on the prior art. When the processing table structure 9 moves to one side of the gantry 2, the sliced electrode sheet can be blocked by the transfer structure 7 arranged inside the gantry 2 and in a fixed state, and thus transferred to the top of the receiving table board 901; At the same time, when the electric push rod 905 controls the receiving table board 901 to rotate around its hinge point with the support plate 904, the electrode sheet on the top of the receiving table board 901 can slide down along the inclined plane to the bottom; As Figures 3 - 6 shown, two multi-stage telescopic tubes 906 are arranged at the inner wall of the bottom of one end of the waste receiving hopper 903. Both multi-stage telescopic tubes 906 are composed of a plurality of square tubes sleeved step by step; Among them, by hinging the outermost one of the multiple square tubes to one end of the electric push rod 905, fixing the innermost one of the multiple square tubes to the bottom inner wall at one end of the waste receiving hopper 903, and inserting one end of the pin block 907 into the inside of the strip-shaped groove 11, the waste receiving hopper 903 is received at the bottom of one end of the support plate 904. When the electric push rod 905 controls the receiving table plate 901 to rotate around its hinge point with the support plate 904, with the cooperation of the multi-stage telescopic tube 906 and the pin block 907 and the strip-shaped groove 11, the waste receiving hopper 903 is pushed to slide out to one side at the bottom of the support plate 904, realizing that when the receiving table plate 901 rotates at one end of the support plate 904, the waste receiving hopper 903 slides out from the bottom of one end of the support plate 904; Such as Figure 1 、 Figure 4 and Figure 5 As shown in the figure, the dust suction structure 8 includes a dust suction hood 801. The cross-section of the dust suction hood 801 is U-shaped. A plurality of small holes for dust suction are processed on the inner wall of the dust suction hood 801. The outer wall of the dust suction hood 801 is assembled and connected with a dust suction pipe 803 communicated with the plurality of small holes. One end of the dust suction pipe 803 is assembled and connected with a dust collector body 804; At the top of a corner of the bearing chassis 1, two symmetrically arranged corner blocks 806 are assembled and connected. A material receiving trough frame 802 is assembled and connected between the two corner blocks 806. The top of the two corner blocks 806 is assembled and connected with a dust suction support 805. The top of the dust suction support 805 is assembled and connected with two corner frames 808. At the bottom on one side of the dust suction support 805, a proximity switch 807 is assembled and connected; Among them, one side of the two corner frames 808 is assembled and fixed to the outer wall of the dust suction hood 801. When the electric push rod 905 controls the receiving table plate 901 to rotate around its hinge point with the support plate 904 and uses the multi-stage telescopic tube 906 to push the waste receiving hopper 903 to slide out to one side at the bottom of the support plate 904, when the waste receiving hopper 903 extends close to the proximity switch 807, the proximity switch 807 is turned on to connect the internal circuit of the dust collector body 804 (here, the working principle of the proximity switch 807 refers to the known technology, and for the internal circuit of the dust collector body 804 that is not the part emphasized in this application, the existing technology can be directly applied. This application only discloses the installation position and activation method of the proximity switch 807). When the receiving table plate 901 discharges materials to one side of the dust suction structure 8, the dust collector body 804 can suck the electrode sheets and dust through the dust suction pipe 803 and the dust suction hood 801.

[0021] In the above design, during the process that the processing table structure 9 reciprocates back and forth inside the gantry 2 under the control of the lead screw assembly A3, the completed sliced lithium battery electrode sheets are blocked by the transfer structure 7 and transferred from the top of the processing table plate 902 to the top of the receiving table plate 901 (such as Figure 2As shown in the figure, it is transferred from area A to area B), while the top of the processing platen 902 continues to place the unprocessed electrode sheets. The receiving platen 901 is controlled by the electric push rod 905 to rotate around its hinge point with the support plate 904, so that the electrode sheets slide down along the inclined plane to one side of the dust suction hood 801; During this process, by means of the multi-stage telescopic tube 906 in cooperation with the pin block 907 and the strip groove 11, the waste receiving hopper 903 can be synchronously pushed to slide out to one side at the bottom of the support plate 904 to pick up the large-volume waste generated during the laser slicing process. At the same time, by extending the waste receiving hopper 903 close to the proximity switch 807, the proximity switch 807 is turned on to connect the internal circuit of the vacuum cleaner body 804, so that the vacuum cleaner body 804 can suck the electrode sheets and dust through the dust suction pipe 803 and the dust suction hood 801 (because the electrode sheets are much heavier than the waste due to their own weight and slide farther along the surface of the receiving platen 901, they can be sucked inside the dust suction hood 801); Subsequently, when the electric push rod 905 is reset and the receiving platen 901 is controlled to rotate around its hinge point with the support plate 904 to be flattened, with the help of the multi-stage telescopic tube 906, the waste receiving hopper 903 is driven to retract to the bottom of one end of the support plate 904 and away from the proximity switch 807, thereby cutting off the power supply to the vacuum cleaner body 804. At this time, the electrode sheets adsorbed to the inside of the dust suction hood 801 fall to the inside of the material receiving trough rack 802 under the influence of their own gravity (here, the unloading and dust removal operations are combined into the same operation step), which is convenient for centralized transfer to the next process.

[0022] Embodiment 2: Based on Embodiment 1, as Figure 1 、 Figure 2 、 Figures 7 - 10 shown, this embodiment introduces the specific structure of the transfer structure 7. The transfer structure 7 includes a push plate 701. Shaft rods 702 are integrally formed at both ends of the push plate 701. An outer bearing 703 is in interference fit with one end of the shaft rod 702, and an outer bushing 704 is in interference fit with the bearing 703. A seat frame 705 is machined at one end of the bushing 704; Among them, the processing platen 902 is made of multiple aluminum alloy profiles processed into plate shapes. The lithium battery electrode sheets are supported and processed on the top of the processing platen 902. The waste generated by slicing the electrode sheets can fall into the channels of the aluminum alloy profiles to ensure that the surface of the entire processing platen 902 is clean; Secondly, by assembling the seat frame 705 between both sides of the gantry 2, when the processing table structure 9 moves inside the gantry 2, the electrode sheets can be pushed from the top of the processing platen 902 to the top of the receiving platen 901 by one side of the push plate 701 (the small-volume debris generated during the electrode sheet processing process falls into the channels of the aluminum alloy profiles); As Figures 7 - 10As shown, a bushing 708 is inserted into the interior of one end of an aluminum alloy profile at the center of the processing platen 902. Three key pins B711 and one key pin A709 are machined on the outer wall of one end of the bushing 708. A shaft column 707 is rotatably connected to the interior of one end of the bushing 708. A push rod 706 perpendicular to the axis is machined on the top of the shaft column 707; One end of the shaft column 707 is integrally formed with a support rod 712, and a torsion spring 710 is sleeved outside the support rod 712; Among them, by keying the interior of the aluminum alloy profile with three key pins B711 and one key pin A709, when the bushing 708 is inserted into the interior of one end of the aluminum alloy profile, the bushing 708 can be fixed to the aluminum alloy profile; Secondly, by fixing the two ends of the torsion spring 710 to the interior of the bushing 708 and the support rod 712 respectively, one end of the key pin A709 extends to one side of the shaft column 707, blocking the push rod 706 from driving the shaft column 707 to rotate inside the bushing 708 under the action of the torsion spring 710, so that the push rod 706 can be in a vertically upward state; Furthermore, when the processing table structure 9 is driven by the lead screw assembly A3 to move from one side to the other side inside the gantry 2 (from Figure 2 point A to point B in the figure), one side of the push rod 706 is blocked by one end of the key pin A709 to push up the push plate 701, causing the push plate 701 to rotate around the shaft rod 702, leaving a space between the push plate 701 and the surface of the processing platen 902 for the electrode sheet to be processed to pass through; At the same time, when the processing table structure 9 is driven by the lead screw assembly A3 to move from the other side to one side inside the gantry 2 (from Figure 2 point B to point A in the figure), one end of the push rod 706 is blocked by one side of the push plate 701, driving the shaft column 707 to rotate inside the bushing 708 to twist the torsion spring 710 tightly, so that the push plate 701 can cross one end of the push rod 706 without being blocked by it.

[0023] The above design, when the processing table structure 9 is driven by the lead screw assembly A3 to make a reciprocating motion inside the gantry 2, uses the bushing 708 installed inside an aluminum alloy profile on the processing platen 902 to support the shaft column 707 with the push rod 706. When the processing platen 902 carries the electrode sheet to be processed and moves to the bottom of the laser slicing device main body 10, one side of the push rod 706 is blocked by one end of the key pin A709 to push up the push plate 701, causing the push plate 701 to rotate around the shaft rod 702, which is beneficial to leaving a space between the push plate 701 and the surface of the processing platen 902 to provide enough space for the electrode sheet to be processed to pass through; Meanwhile, when it is necessary to transfer the processed electrode sheet from the top of the processing platen 902 to the top of the receiving platen 901, one end of the ejector rod 706 is blocked by one side of the push plate 701, driving the shaft column 707 to rotate inside the bushing 708 to tighten the torsion spring 710 (after the push plate 701 crosses the ejector rod 706, with the help of the reset of the torsion spring 710, the ejector rod 706 is reset to the state supported by one end of the pin key A709). When the push plate 701 crosses one end of the ejector rod 706, the electrode sheet and small-volume debris generated during the processing of the electrode sheet can move from the top of the processing platen 902 to the top of the receiving platen 901, and the small-volume debris falls into the channel of the aluminum alloy profile during this process; It should be noted that through the above processing table structure 9 driven by the lead screw assembly A3 to reciprocate inside the gantry 2, the processed electrode sheet is transferred from the top of the processing platen 902 to the top of the receiving platen 901 during the blanking process of the electrode sheet, and the processed electrode sheet is unloaded during the slicing process of the electrode sheet by the laser slicing device main body 10, which is beneficial to shortening the waiting time and improving the processing efficiency.

[0024] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
