Description

Technical Field

[0001] The present application relates to the field of laser cutting technology, and in particular to a laser cutting jig and a laser cutting system. Background Art

[0002] The pole piece of a battery usually includes a current collector and an active material layer loaded on the current collector. In order to improve the production efficiency of the battery, especially for laminated batteries, in the pole piece production process, a larger original pole piece (length and / or width) is usually prepared first, and then the original pole piece is cut into smaller target pole pieces using a cutting device.

[0003] Related technologies use laser cutting equipment to cut the pole piece. In the process of laser cutting, the original pole piece needs to be fixed on the laser cutting jig first. There is a circle of cutting grooves on the laser cutting jig. After the laser cutting equipment is started, it will emit laser and control the laser to route along the cutting groove. After the laser has traveled along the cutting groove for a circle, a target pole piece with a specific pattern will be obtained. Then the original pole piece is moved and the process of laser routing along the cutting groove is repeated to obtain the next target pole piece. Please refer to Figure 1 After laser cutting, multiple hollow cutting tracks B will be left on the original pole piece A. There will be a spacing area between two adjacent cutting tracks B. In the moving direction of the original pole piece, the width H of this spacing area is 5mm to 8mm. The existence of the spacing area will cause material waste and increase the production cost of the pole piece. Utility Model Content

[0044] First, see Figures 3 to 8 The embodiment of the present application provides a laser cutting tool 10, which is used to fix the sheet to be laser cut. The sheet here includes but is not limited to the pole piece in the battery, and the pole piece can be a positive pole piece or a negative pole piece. When in use, the laser cutting tool 10 cooperates with a laser cutting device (not shown in the figure), and the laser cutting tool 10 first fixes the sheet to be cut, and then the laser cutting device performs laser cutting on the fixed sheet.

[0045] Specifically, the laser cutting tool 10 includes a carrier platform 1, which is used to carry the sheet to be cut. An adsorption area 1a is provided on the carrier platform 1, and the adsorption area 1a refers to the area on the carrier platform 1 used to adsorb and fix the sheet to be cut. That is to say, the laser cutting tool 10 fixes the sheet by vacuum adsorption. In order to achieve adsorption and fixation, adsorption through holes 11 are distributed in the adsorption area 1a, and the adsorption through holes 11 are arranged through the carrier platform 1 along the thickness direction of the carrier platform 1. Optionally, the number of adsorption through holes 11 is multiple, and the multiple adsorption through holes 11 are arranged at intervals in the adsorption area 1a. As an example, the multiple adsorption through holes 11 are arranged at equal intervals in the adsorption area 1a. When in use, the laser cutting tool 10 needs to cooperate with a vacuum device (not shown) to achieve vacuum adsorption. The vacuum device specifically refers to a device for generating negative pressure, such as a vacuum air pump. As an example, the vacuum equipment is provided with a suction head, which creates negative pressure on the first side of the loading platform 1 (for example, the side corresponding to the back side). Under the action of the negative pressure, the air on the second side of the loading platform 1 (for example, the side corresponding to the front side) can pass through the adsorption through hole 11 to flow to the first side of the loading platform 1. If a sheet is placed in the adsorption area 1a, the sheet will block the air flow from the second side of the loading platform 1 to the first side of the loading platform 1, and under the action of the negative pressure, the sheet is adsorbed on the loading platform 1, thereby achieving adsorption and fixation of the sheet.

[0046] Here, the adsorption area 1a can be a local area or the entire area on the carrier platform 1. As an example, see Figure 1 , the adsorption area 1a is a local area on the loading platform 1, and the loading platform 1 is also provided with a support area 1b. In the support area 1b, the loading platform 1 is not provided with an adsorption through hole 11. In this way, even if the vacuum equipment creates negative pressure on the first side of the loading platform 1, the surface of the support area 1b will not adsorb the sheet to be cut. The support area 1b is only used to support the sheet to be cut, and the sheet to be cut is carried on the support area 1b. Optionally, the support area 1b is adjacent to the adsorption area 1a, and the surface of the adsorption area 1a and the surface of the support area 1b are coplanar. In this way, the sheet to be cut is placed on the loading platform 1. When a part of the sheet to be cut is adsorbed on the adsorption area 1a, a certain degree of deformation will occur. By using the support area 1b to support another part of the sheet to be cut, the overall deformation of the sheet to be cut can be reduced, thereby ensuring the cutting accuracy.

[0047] In detail, in the adsorption area 1a, a cutting groove 12 is also provided on the carrier platform 1. The cutting groove 12 is an air-avoiding groove for routing the laser emitted by the laser cutting device when the laser cutting device cuts the sheet. Usually, the laser cutting device emits a laser that travels around the cutting groove 12 to cut the target sheet with a specific pattern. Here, the cutting groove 12 can be a groove formed by the surface of the adsorption area 1a on the carrier platform 1 being concave inward, or it can be a hollow groove provided in the adsorption area 1a and penetrating the carrier platform 1 along the thickness direction of the carrier platform 1.

[0048] As an example, the cutting groove 12 is a hollow groove set through the loading platform 1, so that when the vacuum equipment creates negative pressure on one side of the loading platform 1, the cutting groove 12 can also be used to adsorb and fix the sheet to be cut. Optionally, the width of the hollow groove is 2mm to 3mm. In the related art, the cutting groove 12 is usually only 1mm, which leads to poor compatibility of the laser cutting tool 10. When the size of the target sheet to be cut is slightly different, the laser cutting tool 10 must also be replaced. By increasing the width of the cutting groove 12, the compatibility of the laser cutting tool 10 with different target sheets can be improved. Of course, the width of the hollow groove cannot be too large. If the width of the hollow groove is too large, the sheet to be cut will be concave and deformed at the hollow groove during the vacuum adsorption process, affecting the cutting accuracy and shape of the target sheet. By setting the width of the hollow groove to 2mm to 3mm, within this range, the laser cutting tool 10 not only has a certain compatibility with the target sheet but also helps to ensure the cutting accuracy of the target sheet. As an example, the width of the hollow groove is 2.0 mm, 2.1 mm, 2.2 mm, 2.3 mm, 2.4 mm, 2.5 mm, 2.6 mm, 2.7 mm, 2.8 mm, 2.9 mm or 3.0 mm.

[0049] In more detail, the cutting groove 12 defines at least two adjacent pattern cutting areas 13. Figure 3 , the dotted line in the figure shows the pattern cutting area 13, where the pattern cutting area 13 refers to the area on the carrier platform 1 corresponding to the cutting track of a single target sheet when the laser cutting device cuts the sheet through the carrier platform 1. Since the laser light is routed along the cutting groove 12 when the laser cutting device cuts the sheet, the boundary of the pattern cutting area 13 is naturally located in the cutting groove 12. The extension direction of the cutting groove 12 determines the extension direction of the boundary of the pattern cutting area 13, so the cutting groove 12 ultimately determines the shape and number of the pattern cutting area 13. This means that the pattern cutting area 13 is defined by the cutting groove 12.

[0050] The adjacent arrangement of two pattern cutting areas 13 means that there is no overlap between the pattern cutting area 13 and the pattern cutting area 13, but there is a common boundary. Here, the common boundary can be a point or a line. As an example, the cutting groove 12 defines two tangential circular pattern cutting areas 13, and the common boundary here is a point.

[0051] Here, the cutting groove 12 defines at least two adjacent pattern cutting areas 13, which means that a single cutting groove 12 can define multiple pattern cutting areas 13, and there is a common boundary between the multiple pattern cutting areas 13, and there is no isolated pattern cutting area 13. Multiple means two or more. As an example, the cutting groove 12 defines two pattern cutting areas 13, and the two pattern cutting areas 13 are distributed in the shape of a Chinese character 'Ri' (日), and the common boundary is a side line. As an example, the cutting groove 12 defines four pattern cutting areas 13, and the four pattern cutting areas 13 are distributed in the shape of a Chinese character 'Tian' (田), and the common boundary is four side lines. It should be noted here that a single cutting groove 12 can define multiple pattern cutting areas 13, and the shapes of the pattern cutting areas 13 can be the same or different, which is not limited here. All the groove segments in a single cutting groove 12 are connected, and there is no isolated groove segment.

[0052] The laser cutting jig 10 provided by the embodiment of the present application sets the cutting groove 12 in the adsorption area 1a of the loading platform 1, and the cutting groove 12 defines at least two adjacent pattern cutting areas 13. Then there will be a common boundary between the pattern cutting areas 13. When using the laser cutting jig 10 to cooperate with the laser cutting equipment to cut the sheet material, at least two adjacent target sheet materials can be obtained each time of cutting, improving the cutting efficiency while increasing the number of target sheet materials cut on the sheet material per unit area, thereby improving the utilization rate of the sheet material and reducing waste.

[0053] To more clearly illustrate the advantages of the laser cutting jig 10 provided by the embodiment of the present application, the laser cutting jig 10 provided by the embodiment of the present application is used to cooperate with the laser cutting equipment to cut the original pole piece into the target pole piece. Please refer to Figure 2 , Figure 2 Shown is the top view structure diagram of the original pole piece after laser cutting. As can be seen from Figure 2 , the number of the spacer areas (the width is also H) is 3, and the number of the obtained target pole pieces is 8. Please refer to Figure 1 , Figure 1 Shown is the top view structure diagram of the original pole piece after laser cutting in the related art. As can be seen from Figure 1It can be seen that the number of spacing areas (width is also H) is 5, and the number of target pole pieces cut is 6. It can be seen that compared with the related art, the original pole pieces of the same area can be cut to obtain more target pole pieces after the laser cutting fixture 10 provided in the embodiment of the present application is used, the utilization rate of the original pole pieces is improved, and material waste is reduced.

[0054] In some embodiments, see Figures 3 to 5 , the cutting groove 12 includes an annular groove 121 and a separation groove 122. The annular groove 121 generally refers to a circle of grooves located in the outermost layer of the cutting groove 12, and the separation groove 122 generally refers to a groove located in the annular groove 121 in the cutting groove 12, and both ends of the separation groove 122 are connected to the annular groove 121. That is to say, the number of the annular groove 121 is one, and the number of the separation grooves 122 can be one or more. When the number of the separation grooves 122 is multiple, the multiple separation grooves 122 can be arranged to intersect (that is, to achieve communication between the two), or the multiple separation grooves 122 can be arranged at intervals. The cutting groove 12 defines at least two adjacent pattern cutting areas 13, that is, the annular groove 121 and the separation groove 122 jointly define at least two adjacent pattern cutting areas 13, and the two adjacent pattern cutting areas 13 share the same separation groove 122, that is, the common boundary between the two adjacent pattern cutting areas 13 is the edge line.

[0055] As an example, see Figure 5 When using the laser cutting fixture 10 in conjunction with the laser cutting equipment to cut the sheet, starting from point c, first go around the annular groove 121, you can go clockwise or counterclockwise, here we take the counterclockwise direction as an example, the laser light route is c→d→e→f→g→h→c, after returning to point c, go along the separation groove 122, the route is c→f, and the sheet cutting is completed. Compared with the related art, every time two target sheets are cut, the route c→f can be saved, thereby improving the cutting efficiency.

[0056] In some embodiments, see Figures 3 to 5 , both ends of the separation groove 122 protrude from the annular groove 121 respectively, so that when the laser light is routed along the separation groove 122, the routing length of the laser light can be appropriately extended to both ends of the separation groove 122 to ensure the cutting of the sheet and reduce the probability of two adjacent target sheets being connected together. Optionally, the length of the protrusions from the annular groove 121 at both ends of the separation groove 122 is 1mm to 2mm. As an example, the length of one end of the separation groove 122 protruding from the annular groove 121 is 1mm, 1.2mm, 1.4mm, 1.6mm, 1.8mm or 2mm; the length of the protrusion from the other end of the separation groove 122 from the annular groove 121 is 1mm, 1.2mm, 1.4mm, 1.6mm, 1.8mm or 2mm.

[0057] In some embodiments, see Figures 6 to 8 , the loading platform 1 includes a support plate 101 and an adsorption plate 102. Specifically, a hollow area 1011 is provided on the support plate 101, and the hollow area 1011 is obtained by partially hollowing out the support plate 101. The adsorption plate 102 refers to a plate body used for adsorbing and fixing the sheet material, and the adsorption plate 102 is provided with adsorption through holes 11. Of course, this does not mean that adsorption through holes 11 cannot be provided on the support plate 101. In one case, some adsorption through holes 11 can also be provided on the support plate 101. Usually, when only the adsorption through holes 11 are provided on the adsorption plate 102, the hollow area 1011 overlaps with the adsorption area 1a. When the adsorption through holes 11 are also provided on the support plate 101, the adsorption area 1a is larger than the hollow area 1011, and the hollow area 1011 is located in the adsorption area 1a.

[0058] There are multiple adsorption plates 102, and the multiple adsorption plates 102 are all located in the hollow area 1011, and the side of each adsorption plate 102 is spaced from the support plate 101, specifically, the side of the adsorption plate 102 is opposite to the inner side wall of the hollow area 1011 on the support plate 101 and there is a gap, and the gap is formed as an annular groove 121. Multiple adsorption plates 102 are arranged at intervals, specifically, multiple adsorption plates 102 are arranged at intervals edge to edge, so that there is also a gap between the edges of two adjacent adsorption plates 102, and the gap is formed as a separation groove 122. In this way, one adsorption plate 102 corresponds to one pattern cutting area 13. Optionally, the support plate 101 and the adsorption plate 102 are both flat plates, and the support plate 101 is parallel to the adsorption plate 102, and the adsorption plates 102 are also parallel to each other.

[0059] Since the adsorption plate 102 is arranged in the hollow area 1011 at an interval relative to the support plate 101, the loading platform 1 also includes a support portion 103, which is used to support and fix the adsorption plate 102. Specifically, the support portion 103 is fixed on the support plate 101, the support portion 103 usually corresponds to the hollow area 1011, the support portion 103 is located on the back of the adsorption plate 102, and the adsorption plate 102 is supported on the support portion 103. Usually, the adsorption plate 102 has a front side for carrying the sheet material, and the back side of the adsorption plate 102 refers to a side surface of the adsorption plate 102 opposite to its front side. As an example, the support portion 103 includes a supporting protrusion, which is a protrusion protruding on the inner side wall of the hollow area 1011, and the number of the supporting protrusions is multiple, and the multiple supporting protrusions are distributed on the inner side wall of the hollow area 1011 at intervals.

[0060] As an example, the support portion 103 includes a support bar, which is arranged in the hollow area 1011 and crosses the hollow area 1011, and both ends of the support bar are fixedly connected to the support plate 101, and the adsorption plate 102 is fixed on the support bar. The number of support bars can be one or more. Optionally, the adsorption plate 102 and the support bar are integrally formed, and a through hole corresponding to the adsorption through hole 11 on the adsorption plate 102 is opened on the support bar. In addition, at the position corresponding to the cutting groove 12, an avoidance groove 1031 is also recessed on the support bar to prevent the support bar from being cut by laser.

[0061] In some embodiments, the adsorption through hole 11 includes a first through hole 111 and a second through hole 112, wherein the first through hole 111 is arranged on the adsorption plate 102, and the second through hole 112 is arranged on the support plate 101 around the annular groove 121. The number of the first through hole 111 may be one or more. Optionally, the number of the first through hole 111 is multiple, and the multiple first through holes 111 are arranged at intervals on the adsorption plate 102. The number of the second through hole 112 may be one or more. Optionally, the number of the second through hole 112 is multiple, and the multiple second through holes 112 are arranged at intervals on the support plate 101 around the annular groove 121. Since the adsorption plate 102 and the support plate 101 are arranged at intervals, the annular groove 121 defined by the two is a hollow groove. When the sheet is placed on the loading platform 1, when the vacuum device is started, the position of the annular groove 121 can also form a negative pressure, thereby forming a force to pull the sheet into the annular groove 121, and the sheet is easy to sink and deform, which not only affects the cutting accuracy of the target sheet, but also may cause the sheet to be unable to be cut. By opening a first through hole 111 on the adsorption plate 102 and a second through hole 112 on the support plate 101, when the vacuum device is started, the sheet is adsorbed and fixed through the first through hole 111 and the second through hole 112, the deformation of the sheet corresponding to the position of the annular groove 121 is alleviated, and the cutting accuracy of the target sheet is ensured. Optionally, the first through hole 111 is a straight through hole. Optionally, the second through hole 112 is a step hole, the step hole has a larger hole section close to the front of the support plate 101, and the step hole has a smaller hole section close to the back of the support plate 101. By setting the second through hole 112 as a stepped hole, and the larger end of the stepped hole is close to the front of the support plate 101, it is beneficial to ensure that the edge of the sheet can be better adsorbed on the front of the support plate 101, reducing the risk of the sheet sinking. Here, the front of the support plate 101 refers to the surface for supporting the sheet, and the back of the support plate 101 is the side surface opposite to the front.

[0062] In some embodiments, on the side away from the support portion 103, the surface of the adsorption plate 102 is coplanar with the surface of the support plate 101. On the side away from the support portion 103, the surface of the adsorption plate 102 is the front of the adsorption plate 102, and on the side away from the support portion 103, the surface of the support plate 101 is the front of the support plate 101, and the front of the adsorption plate 102 is coplanar with the front of the support plate 101. Usually, when the sheet is placed on the loading platform 1, the sheet is mainly located on the front of the adsorption plate 102, but the edge of the sheet may extend onto the support plate 101. By setting the front of the adsorption plate 102 and the front of the support plate 101 to be coplanar, the sheet can be kept flat and the deformation of the sheet during the adsorption fixation process can be reduced.

[0063] In some embodiments, a mounting hole 14 is further provided on the carrier platform 1, and the laser cutting jig 10 further includes a fastener (not shown), which is used to pass through the mounting hole 14 to fix the laser cutting jig 10 to other equipment, such as laser cutting equipment, vacuum equipment, or a separate mounting frame. The carrier platform 1 includes a support plate 101 and an adsorption plate 102, and the mounting hole 14 is provided on the support plate 101 and close to the edge of the support plate 101. Usually, there are multiple mounting holes 14. In other embodiments, other mounting structures may also be provided on the carrier platform 1 to fix the laser cutting jig 10, such as buckles.

[0064] In the second aspect, the embodiment of the present application also provides a laser cutting system, which is used to laser cut the sheet. Specifically, the laser cutting system includes laser cutting equipment, vacuum equipment and the above-mentioned laser cutting jig 10. The laser cutting equipment is provided with a laser cutting head, which is used to emit laser light and use the laser light to cut the sheet. The vacuum equipment is provided with a suction head, which is used to suck the air in the adsorption through hole 11 on the laser cutting jig 10 to achieve adsorption and fixation of the sheet. Among them, the laser cutting head and the suction head are respectively located on the opposite sides of the laser cutting jig 10 and correspond to the adsorption area.

[0065] Optionally, the laser cutting system further comprises a transport device for transporting the sheet, and the transport device is, for example, a transport roller.

[0066] The embodiments of the present application are introduced in detail above.
