Description

Technical Field

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

[0002] Lithium-ion battery electrodes are a coating composed of particles, evenly applied to a metal current collector. Lithium-ion battery electrode coatings can be considered a composite material, primarily consisting of a mixture of active material particles, a conductive agent, and a binder, with pores filled with electrolyte.

[0003] In battery manufacturing, laser technology can be used for electrode slicing, electrode 3D microstructuring, tab slicing, aluminum-plastic film slicing, welding, and marking. Laser processing is used for slicing, annealing, structuring, and 3D printing of lithium-ion battery electrodes, reducing manufacturing costs and improving the electrochemical performance and service life of lithium-ion batteries.

[0004] Patent document CN202934243U discloses a laser slicer for electrode coating and blanking. The laser slicer delivers the electrode sheet flatly to the adsorption base of an adsorption table device through a sheet storage system. The laser blade of the laser slicer is driven by a motor transmission device to slice at a uniform speed. After cutting, a dust collection device is activated to absorb the waste material and dust after slicing. The adsorption device is activated by a transmission device and reaches the position of the adsorption table. The cylinder pushes the movable connecting rod to grab the cut electrode sheet blank and send it to the next process cycle. This realizes the automation of the equipment, greatly improving production efficiency, making it suitable for popularization and application, with a simple structure and easy operation.

[0005] However, in the process of implementing the above technical solution, it was found that the above technical solution had the following technical problems:

[0006] After completing the slicing of the battery cell, the laser slicer used for electrode coating and blanking uses a dust suction device to suck out waste and dust, and uses an adsorption device to grab the cut electrode sheet blanks, which can realize the automation of product production. However, in actual application, the slicing, dust suction and grabbing are carried out successively. In the process of electrode slicing, the overall time is relatively long, which is not conducive to maximizing the production efficiency in the process of automatic electrode slicing. Summary of the Invention

[0007] In order to overcome the problem that the existing laser slicer for electrode sheet coating and blanking performs slicing, dust collection and grabbing in the actual application process, the overall time-consuming process of electrode sheet slicing is long, which is not conducive to maximizing the production efficiency of the electrode sheet automated slicing process, the embodiment of the present application provides a laser slicing device for lithium battery electrode sheets after coating. When the processing table structure is driven by the screw assembly A to make reciprocating motion on the inner side of the gantry, on the one hand, one side of the push rod is blocked by one end of the pin key A to push up the push plate, so that the push plate rotates around the shaft rod, which is conducive to leaving space for the electrode sheet to be processed to pass through on the surface of the push plate and the processing table. 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 column sleeve to tighten the torsion spring. When the push plate crosses one end of the push rod, it can move from the top of the processing table to the top of the receiving table to ensure that the processed electrode sheet is transferred during the electrode sheet blanking process and the processed electrode sheet is removed during the electrode sheet processing process, which is conducive to shortening the waiting time and improving the processing efficiency.

[0008] The technical solution adopted by the embodiment of the present application to solve the technical problem is:

[0011] The bottom of the processing table structure is provided with a bearing chassis, the center of the top of the bearing chassis is assembled and connected with a gantry, the inner side of the top of the gantry is provided with a device support, and the inner side of the bottom of the gantry is provided with a transfer structure; the processing table structure includes a receiving table and a processing table, the bottom of the receiving table is hingedly connected to a support plate, and an electric push rod is hingedly connected between the inside of the support plate and the bottom of one end of the receiving table;

[0012] Among them, the lithium battery electrode sheet is sliced and processed by the laser slicing device body on the top of the processing table, and when the processing table structure moves to the side of the gantry, the sliced electrode sheet is transferred to the top of the receiving table by the transfer structure, and then the electric push rod controls the receiving table to unload to the side of the dust suction structure, and the dust on the electrode sheet is simultaneously removed by the dust suction structure.

[0014] In one possible implementation, a waste receiving bucket is provided on the inner side of one end of the support plate, and strip grooves are processed at the two corners at the top of one end of the waste receiving bucket, and pin blocks are pinned at the two corners of one end of the support plate; one end of the pin block extends into the interior of the strip groove to store the waste receiving bucket at the bottom of one end of the support plate.

[0015] In one possible implementation, two multi-stage telescopic tubes are provided on the bottom inner wall of one end of the waste receiving bucket, and both of the multi-stage telescopic tubes are composed of multiple square tubes that are connected step by step; the outermost one of the multiple square tubes is hinged to one end of the electric push rod, and the innermost one of the multiple square tubes is fixed to the bottom inner wall of one end of the waste receiving bucket. When the electric push rod controls the receiving platform to rotate around the hinge point between it and the support plate, the multi-stage telescopic tube is used in cooperation with the pin block and the strip groove to push the waste receiving bucket to slide to one side at the bottom of the support plate.

[0016] In one possible implementation, the dust suction structure includes a dust suction hood, the cross-section of the dust suction hood is U-shaped, the inner wall of the dust suction hood is processed with a plurality of small holes for dust suction, the outer wall of the dust suction hood is assembled and connected with a dust suction tube connected to the plurality of small holes, and one end of the dust suction tube is assembled and connected to the vacuum cleaner body; when the receiving table is tilted around the hinge rotation with the support plate, large-volume electrode sheet waste slides from the surface of the receiving table to the inside of the waste receiving hopper, and the electrode sheet is adsorbed by the dust suction hood to remove dust.

[0017] In a possible implementation, two symmetrical corner blocks are assembled and connected at the top of one corner of the supporting chassis, a material receiving chute frame is assembled and connected between the two corner blocks, a dust suction bracket is assembled and connected at the top of the two corner blocks, the top of the dust suction bracket is assembled and connected to two corner brackets, and a proximity switch is assembled and connected at the bottom of one side of the dust suction bracket;

[0018] Among them, one side of the two corner brackets is assembled and fixed to the outer wall of the dust hood. When the waste receiving bucket extends from the bottom of one side of the support plate and approaches the proximity switch, the proximity switch connects the internal circuit of the vacuum cleaner body, so that the vacuum cleaner body absorbs the electrode sheet and dust through the dust suction pipe and the dust suction hood.

[0019] In one possible implementation, the transfer structure includes a pushing plate, both ends of which are integrally formed with a shaft rod, one end of the shaft rod is interference fit with a bearing on the outside, the bearing is interference fit with a sleeve on the outside, and one end of the sleeve is processed with a seat frame; the seat frame is assembled between the two sides of the gantry, and when the processing table structure moves inside the gantry, the electrode sheet is pushed from the top of the processing table plate to the top of the receiving table plate with the help of one side of the pushing plate.

[0020] In one possible implementation, the processing table has multiple aluminum alloy profiles processed into a plate shape, supporting the lithium battery electrode sheet to be processed on the top of the processing table, and the waste material cut from the electrode sheet falls into the groove of the aluminum alloy profile.

[0021] In one possible implementation, a column sleeve is inserted into the interior of one end of an aluminum alloy profile at the center of the processing table, and three pin keys B and one pin key A are processed on the outer wall of one end of the column sleeve. The interior of one end of the column sleeve is rotatably connected to a shaft column, and the top of the shaft column is processed with a push rod perpendicular to the axis; the column sleeve is pinned to the interior of one end of the aluminum alloy profile through three pin keys B and one pin key A; the push rod is vertically upward, and when the processing table structure is driven by the screw assembly A to move from one side to the other side on the inner side of the gantry, the push plate is lifted by one end of the push rod, so that it rotates around the shaft rod and crosses the electrode sheet to be processed on the top of the processing table.

[0022] In one possible implementation, a support rod is integrally formed at one end of the shaft column, and a torsion spring is sleeved on the outside of the support rod; the two ends of the torsion spring are respectively fixed to the inside of the column sleeve and the support rod, and one end of the pin key A extends to one side of the shaft column to prevent the push rod from being driven by the torsion spring to rotate inside the column sleeve.

[0023] The beneficial effects of this application are:

[0024] First, in this solution, the electric push rod is used to control the rotation of the receiving table, so that the electrode sheet slides along the side of the inclined surface toward the dust collection hood, and the waste receiving bucket is simultaneously pushed to slide out to one side at the bottom of the support plate. With the help of the waste receiving bucket extending close to the proximity switch, the proximity switch is connected to the internal circuit of the vacuum cleaner body, so that the vacuum cleaner body can suck up the electrode sheet and dust through the dust collection pipe and the dust collection hood. When the electric push rod is reset and the waste receiving bucket is driven away from the proximity switch by the multi-stage telescopic tube, the power is cut off for the vacuum cleaner body, so that the electrode sheet adsorbed to the inside of the dust collection hood falls to the bottom to the inside of the material receiving chute frame under the influence of its own gravity, which is conducive to combining the unloading and dust removal work into the same operation step, thereby shortening the processing time;

[0025] Secondly, in this solution, when the processing table structure is driven by the screw assembly A to make reciprocating motion on the inner side of the gantry, on the one hand, one side of the push rod is blocked by one end of the pin key A to lift the push plate, so that the push plate rotates around the shaft rod, which is beneficial to leaving space on the surface of the push plate and the processing table for the electrode sheet to pass through. 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 column sleeve to tighten the torsion spring. When the push plate crosses one end of the push rod, it can move from the top of the processing table to the top of the receiving table to ensure that the processed electrode sheet is transferred during the electrode sheet unloading process, and the processed electrode sheet is taken out during the electrode sheet processing process, which is beneficial to shorten the waiting time and improve the processing efficiency.

[0042] The technical solution in the embodiments of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0043] Example 1: This example introduces the specific structure of a laser slicing device for lithium battery electrode sheets after coating. Figures 1-6 As shown, it includes a laser slicing device body 10, a processing table structure 9 arranged at the bottom of the laser slicing device body 10, and a dust collection structure 8 arranged on one side of the processing table structure 9. A supporting frame 1 is provided at the bottom of the processing table structure 9. A gantry frame 2 is assembled and connected at the center of the top of the supporting frame 1. A device support 6 is provided on the inner side of the top of the gantry frame 2, and a transfer structure 7 is provided on the inner side of the bottom of the gantry frame 2.

[0044] Among them, the top of the supporting chassis 1 drives the processing table structure 9 to reciprocate from front to back at the bottom of the laser slicing device body 10 by assembling the screw assembly A3, the top of the gantry 2 drives the device support 6 to reciprocate from one side to the other side on the inner side of the gantry 2 by assembling the screw assembly B4, and the inside of the device support 6 drives the laser slicing device body 10 to reciprocate from top to bottom at the device support 6 by assembling the screw assembly C5 (the screw assembly is a technical application in the existing field of lithium battery electrode laser slicing technology and will not be described in detail);

[0045] like Figures 2 to 6 As shown, the processing table structure 9 includes a receiving table 901 and a processing table 902. The bottom of the receiving table 901 is hingedly connected to a support plate 904. An electric push rod 905 is hingedly connected between the inside of the support plate 904 and the bottom of one end of the receiving table 901.

[0046] A waste receiving hopper 903 is provided on the inner side of one end of the support plate 904. The two corners at the top of one end of the waste receiving hopper 903 are processed with strip grooves 11. The two corners at one end of the support plate 904 are pinned with pin blocks 907.

[0047] Among them, by placing the lithium battery electrode sheet on the top of the processing table 902, the laser slicing device body 10 can slice it based on the existing technology. When the processing table structure 9 moves to the side of the gantry 2, the sliced electrode sheet can be blocked by the transfer structure 7 set on the inner side of the gantry 2 and in a fixed state, and then transferred to the top of the receiving table 901;

[0048] At the same time, when the electric push rod 905 controls the receiving platform 901 to rotate around the hinge point between it and the support plate 904, the electrode sheet on the top of the receiving platform 901 can slide down along the slope to the bottom;

[0049] like Figures 3 to 6 As shown, two multi-stage telescopic tubes 906 are provided on the bottom inner wall of one end of the waste receiving hopper 903. Both multi-stage telescopic tubes 906 are composed of a plurality of square tubes connected step by step.

[0050] The outermost one of the plurality of square tubes is hinged to one end of the electric push rod 905, 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 bucket 903, and one end of the pin block 907 extends into the interior of the strip groove 11, so that the waste receiving bucket 903 is stored at the bottom of one end of the support plate 904. When the electric push rod 905 controls the receiving platform 901 to rotate around the hinge point between it and the support plate 904, the multi-stage telescopic tube 906 is used to cooperate with the pin block 907 and the strip groove 11 to push the waste receiving bucket 903 to slide to one side at the bottom of the support plate 904, so that when the receiving platform 901 rotates at one end of the support plate 904, the waste receiving bucket 903 slides out from the bottom of one end of the support plate 904.

[0051] Ruru Figure 1 、 Figure 4 and Figure 5 As shown, the dust collection structure 8 includes a dust collection hood 801, the dust collection hood 801 has a U-shaped cross-section, the inner wall of the dust collection hood 801 is processed with a plurality of small holes for dust collection, the outer wall of the dust collection hood 801 is assembled and connected to a plurality of small holes in communication with the dust collection tube 803, one end of the dust collection tube 803 is assembled and connected to the vacuum cleaner body 804;

[0052] Two symmetrical corner blocks 806 are assembled and connected at the top of one corner of the supporting chassis 1. A material receiving chute frame 802 is assembled and connected between the two corner blocks 806. A dust collection bracket 805 is assembled and connected to the top of the two corner blocks 806. Two corner brackets 808 are assembled and connected to the top of the dust collection bracket 805. A proximity switch 807 is assembled and connected to the bottom of one side of the dust collection bracket 805.

[0053] Among them, one side of the two corner brackets 808 is assembled and fixed to the outer wall of the dust hood 801. When the electric push rod 905 controls the receiving platform 901 to rotate around the hinge point between it and the support plate 904, the multi-stage telescopic tube 906 is used to push the waste receiving bucket 903 to slide to one side at the bottom of the support plate 904. The waste receiving bucket 903 extends close to the proximity switch 807, so that the proximity switch 807 is connected to the internal circuit of the vacuum cleaner body 804 (here, the working principle of the proximity switch 807 refers to the known technology, and the part of the internal circuit of the vacuum cleaner body 804 that does not need to be emphasized in this application can be directly applied to the existing technology. This application only discloses the setting position and starting method of the proximity switch 807). When the receiving platform 901 unloads material to one side of the dust collection structure 8, the vacuum cleaner body 804 can absorb the electrode sheets and dust through the dust collection pipe 803 and the dust collection hood 801.

[0054] The above design allows the processing table structure 9 to be controlled by the screw assembly A3 to reciprocate back and forth inside the gantry 2, so that the sliced lithium battery electrode sheet is blocked by the transfer structure 7 and transferred from the top of the processing table 902 to the top of the receiving table 901 (as shown in FIG. Figure 2 As shown in FIG, the electrode sheet is transferred from area A to area B), while the unprocessed electrode sheet continues to be placed on the top of the processing plate 902. The electric push rod 905 controls the receiving plate 901 to rotate around the hinge point between it and the support plate 904, so that the electrode sheet slides along the slope toward the side of the dust collection cover 801;

[0055] During this process, the multi-stage telescopic tube 906, in conjunction with the pin block 907 and the strip groove 11, can synchronously push the waste receiving bucket 903 to slide out to the side at the bottom of the support plate 904 to receive the large volume of waste generated during the laser slicing process. At the same time, the waste receiving bucket 903 is extended close to the proximity switch 807, so that the proximity switch 807 connects to the internal circuit of the vacuum cleaner body 804, allowing the vacuum cleaner body 804 to absorb the electrode sheet and dust through the dust collection tube 803 and the dust collection cover 801 (because the electrode sheet is much heavier than the waste, it slides farther along the surface of the receiving platen 901 and can be sucked up inside the dust collection cover 801);

[0056] Subsequently, when the electric push rod 905 is reset and controls the receiving platform 901 to rotate around the hinge point between it and the support plate 904 and to be leveled, the waste receiving bucket 903 is driven to retract to the bottom of one end of the support plate 904 with the help of the multi-stage telescopic tube 906 and away from the proximity switch 807, thereby cutting off the power to the vacuum cleaner body 804. At this time, the electrode sheet adsorbed to the inside of the dust cover 801 falls to the bottom to the inside of the material receiving trough frame 802 due to its own gravity (here the unloading and dust removal work are combined into the same operation step), so as to facilitate centralized transfer to the next process.

[0057] Example 2: Based on Example 1, Figure 1 、 Figure 2 、 Figures 7 to 10 As shown, this embodiment introduces the specific structure of the transfer structure 7, which includes a push plate 701. Both ends of the push plate 701 are integrally formed with a shaft 702. A bearing 703 is interference-fitted on the outside of one end of the shaft 702. A sleeve 704 is interference-fitted on the outside of the bearing 703. A seat 705 is processed on one end of the sleeve 704.

[0058] The processing platen 902 is made of multiple aluminum alloy profiles processed into a plate shape, supporting the lithium battery electrode sheet on the top of the processing platen 902 for processing. The waste material from the electrode sheet can fall into the groove of the aluminum alloy profile to ensure that the surface of the entire processing platen 902 is kept clean.

[0059] Secondly, by assembling the mount 705 between the two sides of the gantry 2, when the processing table structure 9 moves inside the gantry 2, the electrode sheet can be pushed from the top of the processing table 902 to the top of the receiving table 901 by means of one side of the pushing plate 701 (small debris generated during the processing of the electrode sheet falls into the groove of the aluminum alloy profile);

[0060] like Figures 7 to 10 As shown, a column sleeve 708 is inserted into one end of an aluminum alloy profile at the center of the processing table 902. The outer wall of one end of the column sleeve 708 is processed with three pin keys B711 and one pin key A709. The inner part of one end of the column sleeve 708 is rotatably connected to a shaft column 707. The top of the shaft column 707 is processed with a push rod 706 perpendicular to the axis.

[0061] One end of the shaft column 707 is integrally formed with a support rod 712, and the outer portion of the support rod 712 is sleeved with a torsion spring 710;

[0062] Among them, the interior of the aluminum alloy profile is pinned by three pin keys B711 and one pin key A709. When the column sleeve 708 is inserted into the interior of one end of the aluminum alloy profile, the column sleeve 708 can be fixed to the aluminum alloy profile;

[0063] Secondly, by fixing the two ends of the torsion spring 710 to the inside of the column sleeve 708 and the support rod 712 respectively, and extending one end of the pin key A709 to the side of the shaft column 707, the push rod 706 is prevented from rotating inside the column sleeve 708 driven by the torsion spring 710, so that the push rod 706 is kept in a vertical upward position;

[0064] Furthermore, the processing table structure 9 is driven by the screw assembly A3 to move from one side to the other side inside the gantry 2 (by Figure 2 When the push plate 701 moves from point A to point B in the middle, one side of the push rod 706 is blocked by one end of the pin key A709, which pushes up the push plate 701, causing the push plate 701 to rotate around the shaft 702, leaving space between the push plate 701 and the surface of the processing table 902 for the electrode sheet to be processed to pass through;

[0065] At the same time, when the processing table structure 9 is driven by the screw assembly A3 to move from the other side to the side inside the gantry 2 (by Figure 2 When the push plate 701 moves from point B to point A), 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 column sleeve 708 to tighten the torsion spring 710, so that the push plate 701 can cross over one end of the push rod 706 without being blocked by it.

[0066] The above design utilizes a column sleeve 708 mounted on the inside of an aluminum alloy profile on the processing table 902 to support the shaft column 707 with the push rod 706 when the processing table structure 9 is driven by the screw assembly A3 to make reciprocating motion on the inner side of the gantry 2. When the processing table 902 carries the electrode sheet to be processed and moves to the bottom of the laser slicing device body 10, one side of the push rod 706 is blocked by one end of the pin key A709 to lift the push plate 701, so that the push plate 701 rotates around the shaft rod 702, which is conducive to leaving space between the push plate 701 and the processing table 902, providing sufficient space for the electrode sheet to be processed to pass through.

[0067] At the same time, when it is necessary to transfer the processed electrode sheet from the top of the processing table 902 to the top of the receiving table 901, one end of the push rod 706 is blocked by one side of the pushing plate 701, driving the shaft column 707 to rotate inside the column sleeve 708 to tighten the torsion spring 710 (after the pushing plate 701 crosses over the push rod 706, the torsion spring 710 is used to reset the push rod 706 to a state supported by one end of the pin key A709). When the pushing plate 701 crosses over one end of the push rod 706, the electrode sheet and small debris generated during the processing of the electrode sheet can be moved from the top of the processing table 902 to the top of the receiving table 901. The small debris falls into the groove of the aluminum alloy profile during this process.

[0068] It is worth noting that the above-mentioned processing table structure 9 is driven by the screw assembly A3 to make reciprocating motion on the inner side of the gantry 2, so that the processed electrode sheet is transferred from the top of the processing table 902 to the top of the receiving table 901 during the electrode sheet unloading process. The processed electrode sheet is removed and unloaded during the slicing process of the electrode sheet by the laser slicing device body 10, which is conducive to shortening the waiting time and improving the processing efficiency.

[0069] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all embodiments. However, obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
