[0063] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0064] Unless otherwise defined, all technical and scientific terms used in the present invention have the same meanings as commonly understood by those skilled in the art to which the present invention belongs. The terms used in the present invention and the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The terms "including" and "having" and any variations thereof in the present invention and the claims and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first" and "second" in the present invention and the claims and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order or a primary-secondary relationship.

[0065] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connected," and "attached" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0066] The term "and / or" in this disclosure simply describes an association between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this disclosure generally indicates that the related objects are in an "or" relationship.

[0067] In the embodiments of the present invention, identical reference numerals denote identical components, and for the sake of brevity, detailed descriptions of identical components in different embodiments are omitted. It should be understood that the thickness, length, width, and other dimensions of various components in the embodiments of the present invention, as well as the overall thickness, length, width, and other dimensions of the integrated device shown in the drawings, are merely illustrative and do not constitute any limitation on the present invention.

[0068] The term "plurality" used in the present invention refers to two or more (including two).

[0069] The following combination Figures 1 to 14 The plate cutting system 100 and the plate cutting method of the present invention are described below.

[0070] like Figures 1 to 8 As shown, a plate cutting system 100 according to a first embodiment of the present invention includes a cutting table 10 , a cutting device 20 and a stacking device 30 .

[0071] The station 101 of the cutting table 10 has a cutting area 102, each of which is provided with a plurality of support portions 103 for supporting the plate; the cutting device 20 is used to cut the plate A to be cut; the stacking device 30 includes a plurality of stepped slicing plates 301 and a toggle member 302, the plurality of stepped slicing plates 301 being provided correspondingly to the cutting area 102 and spaced apart along the first direction F1 (see Figure 5 ), the multiple support parts 103 corresponding to the cutting area 102 are spaced apart and distributed along the first direction F1, the upper surface of the stepped slicing plate 301 includes a plurality of support surfaces 3011, and along the second direction F2, the heights of the plurality of support surfaces 3011 decrease successively, and the first direction F1 and the second direction F2 are perpendicular.

[0072] Multiple stepped slicing plates 301 are constructed to be able to be raised and lowered to switch between a first position and a second position. In the first position, multiple support surfaces 3011 are lower than the upper surface of the support portion 103, or in other words, the support surface 3011 at the highest height is lower than the upper surface of the support portion 103; in the second position, multiple support surfaces 3011 are higher than the upper surface of the support portion 103 and are used to support the cut plate B, or in other words, the support surface 3011 at the lowest height is higher than the upper surface of the support portion 103.

[0073] The toggle member 302 is configured to move between the stepped slicing plates 301 along the second direction F2 when the stepped slicing plates 301 are in the second position to toggle the cut sheets B. In other words, the lower end of the toggle member 302 is positioned between adjacent stepped slicing plates 301, and the toggle member 302 then toggle the plurality of stepped cut sheets B along the second direction in a direction where the height of the plurality of support surfaces 3011 gradually decreases.

[0074] The working process of the plate cutting system 100 is as follows: the plate A to be cut is placed on multiple support parts 103, wherein the stepped slicing plate 301 is in the first position; the cutting device 20 is controlled to cut the plate A to be cut, forming multiple cut plates B distributed along the second direction F2; the stepped slicing plate 301 is controlled to rise to the second position, so that the multiple cut plates B are correspondingly supported on multiple support surfaces 3011, that is, the multiple cut plates B are distributed in a stepped manner; the toggle member 302 is controlled to move along the second direction F2, so that the cut plates B at a higher height fall onto the cut plates B at a lower height, and finally the multiple cut plates B are stacked together; the stacked plates C are removed from the stacking device 30, and the stepped slicing plate 301 is restored to the first position.

[0075] Thus, the automatic stacking of the cut plates B is achieved, the working efficiency is high, and the labor intensity of the staff is reduced.

[0076] It is understood that the upper surface of the stepped slicing plate 301 includes multiple support surfaces 3011, and the heights of the multiple support surfaces 3011 are successively lowered along the second direction F2. Therefore, when the stepped slicing plate 301 rises to the second position and the cut sheets B are supported on the multiple support surfaces 3011, the heights of the multiple cut sheets B are successively lowered. Therefore, when the toggle member 302 moves along the second direction F2, it can toggle the cut sheets B at a higher position onto the cut sheets B at a lower position, thereby achieving the sequential stacking of the multiple cut sheets B. The height difference between adjacent support surfaces 3011 is much greater than the maximum thickness of the sheets, which helps ensure a smooth stacking process.

[0077] For example, for one workstation 101, there may be only one cutting area 102; or, the workstation 101 of the cutting table 10 has multiple cutting areas 102, each cutting area 102 is provided with multiple stepped slicing plates 301, and the arrangement directions of the stepped slicing plates 301 in different cutting areas 102 are different.

[0078] Specifically, the plurality of stepped slicing plates 301 are located between two support portions 103 spaced apart along a first direction F1. It is understood that the first direction F1 and the second direction F2 are different for different cutting areas 102. The first direction F1 and the second direction F2 herein do not refer to specific directions; rather, the first direction F1 and the second direction F2 are determined by the actual plate cutting plan path.

[0079] Exemplarily, the cutting device 20 may be a laser cutting device, or the cutting device 20 may be a roller shear cutting device, or the cutting device 20 may be a pendulum cutting device.

[0080] The toggle member 302 can be a toggle rod or a toggle plate. The movement of the toggle member 302 in the spatial position can be driven by a separate drive assembly, or can also share a set of drive assemblies with the cutting device 20.

[0081] Illustratively, the supporting surfaces 3011 are connected via a connecting surface, and the angle between the supporting surface 3011 and the connecting surface can be an obtuse angle, a right angle, or an acute angle, which can be selected according to actual conditions.

[0082] According to some embodiments of the present invention, reference may be made to Figures 4 to 8 The stacking device 30 further includes a debris receiving member 303 , which is connected between adjacent stepped slicing plates 301 .

[0083] For example, the debris receiving member 303 can be made of either a soft or hard material, and this is not a specific limitation and can be selected based on actual needs. As the height of the plurality of support surfaces 3011 decreases, the height of the debris receiving member 303 also gradually decreases, and the height of the debris receiving member 303 is lower than the height of the supporting portion 3041, thereby allowing debris to be gathered together as much as possible, thereby improving debris collection efficiency.

[0084] In the above technical solution, by providing the debris receiving member 303, the debris dropped due to cutting or vibration can be received, thereby reducing the scattering of the debris into the surrounding environment and reducing the difficulty of collecting the debris.

[0085] In some embodiments, reference may be made to Figure 5 The plurality of stepped slicing plates 301 are all mounted on a mounting plate 305. A reinforcing plate 306 may be connected between the stepped slicing plates 301 and the mounting plate 305 to ensure stable connection and mounting of the stepped slicing plates 301. A debris receiving member 303 is disposed above the mounting plate 305 to reduce the possibility of debris falling onto the mounting plate 305.

[0086] In some embodiments, the mounting plate 305 can be connected to the telescopic end of the telescopic component 307, and the telescopic end of the telescopic component 307 can drive the substrate 6021 to move up and down. The telescopic component 307 is installed on the bracket, and the mounting plate 305 can be connected to a guide column. The bracket is also provided with a guide cylinder, and the guide column is passed through the guide cylinder to guide the movement of the mounting plate 305.

[0087] According to some embodiments of the present invention, reference may be made to Figures 5 to 8 The stacking device 30 also includes a supporting member 304, which is located on one side of the stepped slicing plate 301 in the second direction F2 and close to the support surface 3011 at the lowest height; the supporting member 304 includes a supporting portion 3041 and a stop portion 3042, the height of the supporting portion 3041 is not higher than the support surface 3011 at the lowest height, and the supporting portion 3041 is configured to receive the stacked plate C that falls from the support surface 3011 at the lowest height; the stop portion 3042 is located on the side of the supporting portion 3041 that is away from the stepped slicing plate 301, and the stop portion 3042 is located above the supporting portion 3041 and is arranged at a set angle to the supporting portion 3041.

[0088] In the above technical solution, by setting the stop part 3042, on the one hand, the stop part 3042 can stop the stacked plates, reducing the possibility of the cut plates B falling from the supporting member 304; on the other hand, the stop part 3042 can play the role of regularizing the stacked plates C, that is, aligning the edges of the stacked plates C as much as possible.

[0089] Exemplarily, the height of the bearing part 3041 can be lower than the height of the lowest support surface 3011. Alternatively, the height of the bearing part 3041 can be equal to the height of the lowest support surface 3011. Exemplarily, the set angle can be 90°, 75°, 60°, 45°, etc., which is not limited herein as long as the stop part 3042 has a stop effect.

[0090] In some embodiments, the support part 103 can be configured to support the cutting device 20. Figure 8 The bearing part 304 further comprises a connecting plate 3043 located on the side of the bearing part 3041 away from the stop part 3042, the connecting plate 3043 is connected with the bearing part 3041, and the plurality of stepped sub-plates 301 are connected with the connecting plate 3043.

[0091] According to some embodiments of the present application, the support part 103 can be configured to support the cutting device 20. Figure 4 Figure 5 and Figure 7 The support part 103 comprises a plurality of support bodies 1031 arranged at intervals along the second direction F2, and the cutting device 20 is configured to cut positions corresponding to positions between adjacent support bodies 1031.

[0092] For example, along the first direction F1, the support surfaces 3011 are arranged one by one with the support bodies 1031, or one support body 1031 corresponds to one support surface 3011, or one support surface 3011 corresponds to one support body 1031.

[0093] For example, the plurality of support bodies 1031 arranged at intervals along the first direction F1 are used to support the same cut plate B. The plurality of support bodies 1031 arranged at intervals along the second direction F2 are respectively used to support a plurality of cut plates B.

[0094] The cutting device 20 is configured to cut positions corresponding to positions between adjacent support bodies 1031, so that the cutting device 20 is less likely to cut the support bodies 1031 during cutting of the plate A to be cut, and the support bodies 1031 are less affected, which is conducive to prolonging the service life of the support bodies 1031; meanwhile, the cut plate B can be accurately supported on the support bodies 1031.

[0095] In some embodiments, the support part 103 comprises an adsorption part 1032 configured to adsorb and fix the plate.

[0096] For example, the adsorption part 1032 is a vacuum adsorption part, i.e., the support bodies 1031 adsorb and fix the plate by vacuum adsorption, for example, the upper end surface of the support part 103 is a vacuum adsorption port. Alternatively, the adsorption part 1032 is an electrically controlled magnetic adsorption part, i.e., the support bodies 1031 adsorb and fix the plate by magnetic adsorption, and the plate is a metal plate.

[0097] ​In the technical solution, the plate is fixed by adsorption, so that the plate can be quickly fixed and separated from the support part 103, and the work efficiency is high.

[0098] According to some embodiments of the application, the cutting device 20 is a laser cutting device.

[0099] That is, the embodiment of the application uses laser cutting technology instead of the original roll cutting or shearing technology, and the edge effect of the cut plate B obtained by cutting is good.

[0100] The laser cutting device is also configured to have an automatic edge finding and height following function, and to set different cutting sizes according to the lug specifications. When the specifications of the starting sheet change under different processes, the cutting path, the support part 103 and the stepped segmentation plate 301 distribution can be adjusted according to the actual size. The cutting flexibility is high, the requirement for the flatness of the plate surface is low, and the system adaptability is strong.

[0101] According to some embodiments of the application, reference can be made to Figure 2 and Figure 11 The cutting table 10 includes a three-degree-of-freedom mounting assembly 104 for mounting the cutting device 20 to drive the cutting device 20 to move in three degrees of freedom, and the actuator 302 is arranged on the cutting device 20.

[0102] Exemplarily, the three-degree-of-freedom mounting assembly 104 includes a first guide rail, a second guide rail and a third guide rail, the extension directions of the first guide rail, the second guide rail and the third guide rail are perpendicular to each other in pairs, the first guide rail and the second guide rail extend horizontally, and the third guide rail extends vertically. The first guide rail is provided with two, the second guide rail is arranged on the two first guide rails, the third guide rail is arranged on the second guide rail, the cutting device 20 is mounted on the third guide rail and can move up and down along the third guide rail, the third guide rail is mounted on the second guide rail and can move along the second guide rail, and the second guide rail is mounted on the first guide rail and can move along the first guide rail.

[0103] The cutting device 20 moves in three degrees of freedom, which refers to translational degrees of freedom, so that the cutting device 20 can reach any position of the working position 101 for cutting, and the position of the cutting device 20 in the up-down direction can be followed to change according to the thickness change of the plate.

[0104] The actuator 302 is arranged on the cutting device 20, so that the three-degree-of-freedom mounting assembly 104 can drive the actuator 302 to move in three degrees of freedom without the need to additionally set a driving assembly for driving the actuator 302 to move.

[0105] According to some embodiments of the application, reference can be made to Figure 1 The cutting table 10 has a plurality of working positions 101, and the cutting device 20 is configured to be movable between the plurality of working positions 101.

[0106] By setting multiple workstations 101, multiple workstations 101 can simultaneously perform different processes, for example, one workstation 101 performs the cutting process on the to-be-cut plate A, and another workstation 101 performs the stacking and feeding process of the to-be-cut plate A and the cut plate C, thereby increasing production efficiency and improving the utilization efficiency of the cutting device 20.

[0107] According to some embodiments of the present application, reference can be made to Figure 1 The workstations 101 of the cutting table 10 have multiple cutting areas 102, and the arrangement directions of the stepped slicing plates 301 of different cutting areas 102 are different.

[0108] In the above technical solution, the workstations 101 have multiple cutting areas 102, and for different cutting areas 102, the arrangement directions of the stepped slicing plates 301 are different, or in other words, the cutting directions or cutting paths of the cutting device 20 are different, to adapt to different shapes of the to-be-cut plate A, so that the to-be-cut plate A is maximally utilized.

[0109] At the same time, the cut plates B of different cutting areas 102 can also share part of the poking members 302, to reduce the number of setting of the poking members 302.

[0110] The plate cutting system 100 can also be provided with a scrap collecting box, which can be arranged below the cutting area 102. The remaining plate of the to-be-cut plate A after cutting can fall into the scrap collecting box, to facilitate the work personnel to handle.

[0114] According to some embodiments of the present invention, reference may be made to Figure 10 The plate cutting system 100 further includes a first box 40, a second box 50 and a transport robot 60. The first box 40 is used to store the plate A to be cut, and the second box 50 is used to store the stacked plates C. The transport robot 60 includes a robot body 601, a first clamp 602 and a second clamp 603. The first clamp 602 includes a base plate 6021 and a suction cup 6022. A plurality of suction cups 6022 are provided on the base plate 6021. The suction cup 6022 is used to suck the plate A to be cut. The base plate 6021 is aligned with the free end of the robot body 601. The transport robot arm 60 is configured to transport the plate A to be cut in the first box 40 to the cutting area 102 through the first clamp 602; the second clamp 603 includes a base 6031 and at least one pair of jaws 6032, and the pair of jaws 6032 are installed on the base 6031 in an openable and retractable manner. The base 6031 is connected to the free end of the robot arm body 601, and the jaws 6032 are used to clamp the stacked plate C. The transport robot arm 60 is configured to transport the stacked plate C from the stacking device 30 to the second box 50 through the second clamp 603.

[0115] Exemplarily, the first box body 40 and the second box body 50 can be respectively arranged at two sides of the carrying mechanical arm 60. The first box body 40 and the second box body 50 are both arranged on the support frame 501, the support frame 501 is formed with a positioning column 502, the outer diameter of the positioning column 502 gradually decreases along the direction from top to bottom, the bottom of the first box body 40 and the second box body 50 is formed with a positioning hole 503, and the positioning column 502 is suitable to be inserted into the positioning hole 503, so that each time when the first box body 40 and the second box body 50 are placed on the support frame 501, the first box body 40 can be placed in the same position, and the second box body 50 can be placed in the same position.

[0116] Referring to Figure 13 A plurality of groups of partition plates can be arranged in the second box body 50, each group of partition plates includes two partition plates, and the stacked back plate C is arranged between the two partition plates, and adjacent two groups of partition plates are spaced apart to place the stacked back plate C.

[0117] The movement freedom degree of the mechanical arm body 601 can be selected according to actual needs, which is not specifically limited here.

[0118] Referring to Figure 12 The free end of the mechanical arm body 601 is connected with a clamp mounting disc 604, the clamp mounting disc 604 has a plurality of mounting columns 6041 extending in the radial direction, one end of the plurality of mounting columns 6041 is connected with each other, and the other end of the plurality of mounting columns 6041 is provided with a connecting flange, and the first clamp 602 and the second clamp 603 are detachably connected with the connecting flange, so that the clamps can be conveniently replaced according to needs.

[0119] Exemplarily, the suction cup 6022 of the first clamp 602 can be a vacuum suction cup or a magnetic suction cup. The middle part of the base plate 6021 and the outer side of the base plate 6021 can be provided with a suction cup 6022, so as to increase the adsorption area and increase the adsorption stability when adsorbing the plate.

[0120] Exemplarily, the second clamp 603 includes a base 6031 and two pairs of clamping jaws 6032, the included angle between one pair of clamping jaws 6032 is greater than zero in the open state, and the one pair of clamping jaws 6032 are parallel to each other in the closed state. The two pairs of clamping jaws 6032 are respectively used to support the two end portions in the length direction of the cut back plate B, so as to stabilize the grabbing of the cut back plate B.

[0121] In order to improve the stability of the stacked plate C during the plate transfer process of the second clamp 603, the second clamp 603 also includes an elastic pressing member 605, which is located between the two pairs of clamps 6032. The elastic pressing member 605 includes a first rod body, a second rod body and a spring pressure plate.

The spring pressure plate is used to press the stacked plate C, and the spring is sleeved on the second rod body. The two ends of the spring respectively stop at the spring pressure plate and the first rod body.

[0122] For example, the robot body 601 can be a six-axis robot arm, which can switch between the first clamp 602 and the second clamp 603 under different motions. The first clamp 602's multiple sets of vacuum suction cups 6022 simultaneously hold the surface of the starting electrode. The second clamp 603 uses air grippers to drive two sets of jaws 6032 to grasp the stacking lugs, while a spring pressure plate compresses the stacking lugs to complete the grasping action.

[0123] In this embodiment, the first clamp 602 and the second clamp 603 are integrally mounted on the robot arm body 601 , thereby improving the flexibility and working efficiency of the transport robot arm 60 .

[0124] According to some embodiments of the present invention, the plate A to be cut is a starting plate, and the plate B after cutting is a hanging ear plate.

[0125] The starting electrode sheet is a metal sheet that is cut to form the lugs. The surface of the starting electrode sheet is rough and uneven. As the stepped slabs 301 are stacked and dropped, the lugs will collide and rub against each other. However, even if some degree of deformation occurs, it does not affect the use of the lugs. Therefore, the plate cutting system 100 of the embodiment of the present application is well suited for cutting starting electrode sheets to form lugs and completing the automatic stacking process of the lugs.

[0126] The second aspect of the present invention further provides a plate cutting method.

[0127] According to the plate cutting method of the second aspect of the present invention, based on the plate cutting system 100 in any of the above embodiments, the plate cutting method includes placing the plate A to be cut on multiple support parts 103, wherein the stepped slicing plate 301 is in the first position; controlling the cutting device 20 to cut the plate A to be cut, forming multiple cut plates B distributed along the second direction F2; controlling the stepped slicing plate 301 to rise to the second position, so that the multiple cut plates B are correspondingly supported on multiple support surfaces 3011; controlling the toggle member 302 to move along the second direction F2, so that the cut plates B at a higher height fall onto the cut plates B at a lower height, and finally the multiple cut plates B are stacked together; the stacked plates C are removed from the stacking device 30, and the stepped slicing plate 301 is restored to the first position.

[0128] The plate cutting method according to the second embodiment of the present invention realizes a fully automated process of placing plates, cutting plates, stacking plates and removing plates, has high production efficiency and can reduce the labor intensity of staff.

[0129] According to some embodiments of the present invention, the cutting table 10 has two workstations 101, and the cutting device 20 is configured to be movable between the two workstations 101. During the process of cutting the plate A to be cut located at the workstation 101 on one side, the stacked plate C at the workstation 101 on the other side is removed and the plate A to be cut is placed on the multiple support parts 103 of the workstation 101 on the other side.

[0130] Exemplarily, the transport robot arm 60 can perform pick-and-place operations on the plates at two workstations 101 .

[0131] In the above technical solution, the two workstations 101 operate alternately, which reduces the waiting time of the cutting device 20 when the transport robot arm 60 transfers the plate, speeds up the production speed of the plate cutting system 100, and improves the operating efficiency of the transport robot arm 60.

[0132] According to some embodiments of the present invention, the maximum thickness of the plate A to be cut is obtained, and the cutting power of the cutting device 20 is adjusted to match the cutting power of the cutting device 20 with the maximum thickness of the plate A to be cut.

[0133] The thickness of ordinary plates is relatively uniform, so there is no need to consider the maximum thickness. However, the surface of the starting plate is uneven, and the thickness varies at different locations on the starting plate. Therefore, the maximum thickness of the starting plate must be determined before cutting. In other words, the power that matches the maximum thickness of the starting plate must be used at any location when cutting the starting plate to ensure that the plate A to be cut can be completely cut.

[0134] For example, the maximum thickness of the sheet material A to be cut can be obtained through automatic measurement. For example, after the sheet material A to be cut is placed in the cutting area 102, a thickness measuring component, such as a magnetic thickness gauge or a laser scanner, measures the maximum thickness of the sheet material A to be cut. The control component then adjusts the cutting power of the cutting device 20 based on the maximum thickness of the sheet material A to be cut so that the cutting power of the cutting device 20 matches the maximum thickness of the sheet material A to be cut. This allows the cutting device 20 to fully penetrate the sheet material A to reduce the occurrence of incomplete cutting.

[0135] Alternatively, a manual method may be used, or the maximum thickness of the plate A to be cut may be obtained according to production conditions. For example, a maximum thickness of a batch of plates may be estimated, and the cutting power of the cutting device 20 may be adjusted based on the maximum thickness as a set value.
