Technical Field

[0001] The utility model relates to the technical field of battery manufacturing equipment, in particular to a tool for clamping a stacking assembly. Background Art

[0002] In the process of making all-solid-state batteries, the pole pieces and other materials are first stacked on the stacking table to form a stacking assembly; then the stacking assembly is transferred to the edge sealing station to perform edge sealing on the four edges of the stacking assembly. However, during the transfer of the stacking assembly, the stacked layers of materials are prone to positional offset, resulting in reduced stacking accuracy of the stacking assembly, which in turn has an adverse effect on the quality of the all-solid-state battery containing the stacking assembly. Utility Model Content

[0003] Based on this, it is necessary to provide a tooling for clamping a stacking assembly to improve the above defects in order to address the problem in the prior art that positional offsets are easily generated between the stacked layers of materials during the transfer process of the stacking assembly, resulting in reduced stacking accuracy of the stacking assembly, and further adversely affecting the quality of the all-solid-state battery containing the stacking assembly.

[0005] When the first clamping mechanism clamps the laminate assembly, it blocks a portion of the edge of the laminate assembly; when the second clamping mechanism clamps the laminate assembly, it blocks another portion of the edge of the laminate assembly.

[0006] In one embodiment, the first clamping mechanism includes a first clamping plate and a second clamping plate, and the first clamping plate and the second clamping plate can be respectively covered on the bottom surface and the top surface of the stacking assembly and are configured to clamp the stacking assembly.

[0007] In one embodiment, the first clamping mechanism further includes a first magnetic member, and the first magnetic member is disposed on the first clamping plate and / or the second clamping plate. Under the action of the magnetic force generated by the first magnetic member, the first clamping plate and the second clamping plate jointly clamp the lamination assembly.

[0008] In one embodiment, the second clamping mechanism includes a third clamping plate and a fourth clamping plate, and the third clamping plate and the fourth clamping plate can be respectively covered on the bottom surface and the top surface of the stacking assembly and are configured to clamp the stacking assembly.

[0009] In one embodiment, the second clamping mechanism further includes a second magnetic member, and the second magnetic member is disposed on the third clamping plate and / or the fourth clamping plate. Under the action of the magnetic force generated by the second magnetic member, the third clamping plate and the fourth clamping plate jointly clamp the lamination assembly.

[0010] In one embodiment, the area where the first clamping plate contacts the bottom surface of the laminate assembly is the first area, the area where the third clamping plate contacts the bottom surface of the laminate assembly is the second area, and the first area and the second area do not overlap each other.

[0011] In one embodiment, the area where the second clamping plate contacts the top surface of the laminate assembly is the third area, the area where the fourth clamping plate contacts the top surface of the laminate assembly is the fourth area, and the third area and the fourth area do not overlap each other.

[0012] In one embodiment, the first clamping mechanism further includes a first positioning member, which is mounted on the first clamping plate or the second clamping plate and is used to position the first clamping plate and the second clamping plate.

[0013] In one embodiment, the second clamping mechanism further includes a second positioning member, which is mounted on the third clamping plate or the fourth clamping plate and is used to position the third clamping plate and the fourth clamping plate.

[0014] In one embodiment, the first positioning member and the second positioning member are respectively located on different sides of the laminate assembly, so that the first clamping plate and the second clamping plate and the third clamping plate and the fourth clamping plate respectively cover different edges of the laminate assembly.

[0015] In one embodiment, the tooling further includes a switching mechanism, and the switching mechanism includes a support platform and a lifting unit;

[0016] The support platform is used to carry the first clamping plate and the third clamping plate, and the lifting unit is used to lift the second clamping plate covering the top surface of the stacking assembly so that the second clamping plate is separated from the stacking assembly.

[0017] In one embodiment, the jacking unit includes a first driving component and a jacking block installed at the driving end of the first driving component, and the first driving component is used to drive the jacking block to move to mate with or separate from the first clamping plate, and is also used to drive the jacking block to perform a jacking movement when the jacking block is mated with the second clamping plate.

[0020] When the tooling for clamping the stack assembly is actually used, the stack assembly is first clamped and fixed by the bottom and top surfaces of the stack assembly using the first clamping mechanism. At this time, the first clamping mechanism does not cover all the edges of the stack assembly, that is, part of the edges of the stack assembly are exposed. Then, the edges of the stack assembly that are exposed are edge-sealed. Then, the stack assembly is clamped and fixed by the bottom and top surfaces of the stack assembly using the second clamping mechanism. Then, the first clamping mechanism is removed, so that the stack assembly is clamped and fixed only by the second clamping mechanism. At this time, the edges of the stack assembly that have not been edge-sealed are exposed. Then, the edges of the stack assembly that have not been edge-sealed are edge-sealed, thereby achieving the purpose of completing the edge sealing of all the edges around the stack assembly. Finally, the second clamping mechanism also releases the stack assembly.

[0021] In this way, during the transfer and edge sealing process of the stack assembly, the stack assembly is clamped by using the first clamping mechanism or the second clamping mechanism, that is, the stack assembly is always in a clamped state, thereby avoiding positional offset between the layers of material of the stack assembly, greatly improving the stacking accuracy of the stack assembly, and further facilitating improving the quality of the all-solid-state battery containing the stack assembly.

[0032] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

[0036] See also Figure 1 and Figure 4 One embodiment of the utility model provides a tool for clamping a stacking assembly A, comprising a first clamping mechanism 10 and a second clamping mechanism 20. The first clamping mechanism 10 and the second clamping mechanism 20 can both clamp or release the stacking assembly A by the bottom surface A1 and the top surface A2 of the stacking assembly A, and the first clamping mechanism 10 and the second clamping mechanism 20 can clamp or release the stacking assembly A at the same time. When the first clamping mechanism 10 clamps the stacking assembly A, it blocks part of the edge of the stacking assembly A, so that the blocked edge of the stacking assembly A cannot be edge-sealed at this time, and only the edge of the stacking assembly A in an exposed state (i.e., not blocked) can be edge-sealed. When the second clamping mechanism 20 clamps the stacking assembly A, it blocks another part of the edge of the stacking assembly A, so that the unblocked edge of the stacking assembly A can be edge-sealed at this time. That is, the first clamping mechanism 10 and the second clamping mechanism 20 respectively block different edges of the stacking assembly A.

[0037] It should be noted that the laminate assembly A can be a laminated battery cell of an all-solid-state battery. Of course, in other embodiments, the laminate assembly A can also be other stacked products that need to be edge-sealed, which is not limited here.

[0038] The tooling for clamping the stacking assembly A, when actually used, first uses the first clamping mechanism 10 to clamp and fix the stacking assembly A by the bottom surface A1 and the top surface A2 of the stacking assembly A. At this time, the first clamping mechanism 10 does not cover all the edges of the stacking assembly A, that is, part of the edges of the stacking assembly A are in an exposed state. Then, the edges of the stacking assembly A in an exposed state are edge-sealed. Then, the second clamping mechanism 20 is used to clamp and fix the stacking assembly A by the bottom surface A1 and the top surface A2 of the stacking assembly A. Then, the first clamping mechanism 10 is removed, so that the stacking assembly A is clamped and fixed only by the second clamping mechanism 20. At this time, the edges of the stacking assembly A that have not been edge-sealed are in an exposed state. Then, the edges of the stacking assembly A that have not been edge-sealed are edge-sealed, thereby achieving the purpose of completing the edge sealing of all the edges around the stacking assembly A. Finally, the second clamping mechanism 20 also releases the stacking assembly A.

[0039] In this way, during the transfer and edge sealing process of the stack assembly A, the stack assembly A is clamped by the first clamping mechanism 10 or the second clamping mechanism 20, that is, the stack assembly A is always in a clamped state, thereby avoiding positional offset between the layers of material of the stack assembly A, greatly improving the stacking accuracy of the stack assembly A, and further facilitating improving the quality of the all-solid-state battery containing the stack assembly A.

[0040] It should be noted that when the first clamping mechanism 10 is used to clamp the laminate assembly A, the edge of the laminate assembly A in the shielded state is named as the first edge, and the remaining edges in the exposed state are named as the second edge. At this time, since the second edge of the laminate assembly A is in the exposed state, the second edge of the laminate assembly A can be edge-sealed.

[0041] When the stacking assembly A is clamped by the second clamping mechanism 20, the edge of the stacking assembly A blocked by the second clamping mechanism 20 belongs to the second edge portion (i.e., the edge that has been edge-sealed). At this time, the first edge portion is exposed, so the edge portion can be edge-sealed, so that the edge of all edges around the stacking assembly A can be edge-sealed through two edge-sealing processes.

[0042] Specific to Figure 2In the embodiment shown, the lamination assembly A includes a first edge a1, a second edge a2, a third edge a3 and a fourth edge a4 which are connected end to end in sequence along its own circumference, and the first edge a1, the second edge a2, the third edge a3 and the fourth edge a4 are enclosed together to form a rectangular outer contour. The first edge a1 and the third edge a3 are opposite to each other in a first direction X1, and the second edge a2 and the fourth edge a4 are opposite to each other in a second direction X2, and the first direction X1 is perpendicular to the second direction X2. When the first clamping mechanism 10 clamps the lamination assembly A (see Figures 1 to 3 ), the first clamping mechanism 10 covers the first edge a1 of the laminate assembly A, but does not cover the second edge a2, the third edge a3 and the fourth edge a4 of the laminate assembly A, that is, the second edge a2, the third edge a3 and the fourth edge a4 of the laminate assembly A are exposed. At this time, the second edge a2, the third edge a3 and the fourth edge a4 of the laminate assembly A can be edge-sealed.

[0043] When the second clamping mechanism 20 clamps the lamination assembly A (see Figures 4 to 6 ), the second clamping mechanism 20 blocks the third edge a3 of the laminate assembly A, but does not block the first edge a1, the second edge a2 and the fourth edge a4 of the laminate assembly A, that is, the first edge a1, the second edge a2 and the fourth edge a4 of the laminate assembly A are exposed. At this time, the first edge a1 of the laminate assembly A can be edge-sealed. In this way, after two edge-sealing processes, the edge sealing of all the edges around the laminate assembly A is completed.

[0044] It should be noted that the shape formed by the edges of the stack assembly A is not limited to a rectangle, but may also be other shapes, such as a polygon or an irregular shape, which is not limited here.

[0045] See also Figures 1 to 3 As shown, in the embodiment of the present application, the first clamping mechanism 10 includes a first clamping plate 11 and a second clamping plate 12. The first clamping plate 11 and the second clamping plate 12 can be respectively covered on the bottom surface A1 and the top surface A2 of the stacking assembly A, and are configured to clamp the stacking assembly A. In this way, when the first clamping mechanism 10 is needed to clamp the stacking assembly A, the first clamping plate 11 is first placed on the stacking table, and the stacking material (such as the pole piece) is stacked on the first clamping plate 11 to form the stacking assembly A. After the stacking is completed, the second clamping plate 12 is covered on the top surface A2 of the stacking assembly A, and the first clamping plate 11 and the second clamping plate 12 are made to clamp the stacking assembly A therebetween, thereby achieving the clamping of the stacking assembly A.

[0046] Furthermore, the first clamping mechanism 10 also includes a first magnetic member 13, which is arranged on the second clamping plate 12, so that the first magnetic member 13 generates a magnetic attraction force on the first clamping plate 11. Under the action of the magnetic attraction force generated by the first magnetic member 13, the first clamping plate 11 and the second clamping plate 12 jointly clamp the laminated assembly A therebetween. In this way, the magnetic attraction force generated by the first magnetic member 13 is used to realize that the first clamping plate 11 and the second clamping plate 12 jointly clamp the laminated assembly A, without the need to set up an additional locking mechanism, which greatly simplifies the structure of the tooling and simplifies the operation process. Optionally, the first magnetic member 13 can be a magnet.

[0047] It should be noted that the first magnetic member 13 is not limited to being disposed on the second clamping plate 12. In other embodiments, the first magnetic member 13 may also be disposed on the first clamping plate 11, and the first magnetic member 13 is used to generate a magnetic attraction force on the second clamping plate 12, so that the first clamping plate 11 and the second clamping plate 12 can jointly clamp the laminated assembly A therebetween. In another embodiment, the first magnetic member 13 is disposed on both the first clamping plate 11 and the second clamping plate 12, and the magnetic attraction force is generated between the first magnetic member 13 on the first clamping plate 11 and the first magnetic member 13 on the second clamping plate 12, so that the first clamping plate 11 and the second clamping plate 12 can jointly clamp the laminated assembly A therebetween.

[0048] See also Figures 4 to 6 Specifically, in the embodiment, the second clamping mechanism 20 includes a third clamping plate 21 and a fourth clamping plate 22, which can be respectively covered on the bottom surface A1 and the top surface A2 of the laminate assembly A, and can controllably clamp the laminate assembly A. In this way, when the second clamping mechanism 20 is needed to clamp the laminate assembly A, first, the third clamping plate 21 is covered on the bottom surface A1 of the laminate assembly A, and then the fourth clamping plate 22 is covered on the top surface A2 of the laminate assembly A, and the third clamping plate 21 and the fourth clamping plate 22 are made to clamp the laminate assembly A therebetween. Then, the first clamping plate 11 and the second clamping plate 12 are removed, so that the laminate assembly A is only clamped by the third clamping plate 21 and the fourth clamping plate 22, thereby realizing the clamping of the laminate assembly A by the second clamping mechanism 20.

[0049] Furthermore, the second clamping mechanism 20 also includes a second magnetic member 23, which is arranged on the fourth clamping plate 22, so that the second magnetic member 23 generates a magnetic attraction force on the third clamping plate 21. Under the action of the magnetic attraction force generated by the second magnetic member 23, the third clamping plate 21 and the fourth clamping plate 22 jointly clamp the laminated assembly A therebetween. In this way, the magnetic attraction force generated by the second magnetic member 23 is used to realize the third clamping plate 21 and the fourth clamping plate 22 jointly clamping the laminated assembly A, without the need to set up an additional locking mechanism, which greatly simplifies the structure of the tooling and simplifies the operation process. Optionally, the second magnetic member 23 can be a magnet.

[0050] It should be noted that the second magnetic member 23 is not limited to being set on the fourth clamping plate 22. In other embodiments, the second magnetic member 23 can also be set on the third clamping plate 21, and the second magnetic member 23 is used to generate a magnetic attraction force on the fourth clamping plate 22, so that the third clamping plate 21 and the fourth clamping plate 22 can jointly clamp the laminated assembly A therebetween. In another embodiment, the second magnetic member 23 is provided on both the third clamping plate 21 and the fourth clamping plate 22, and the magnetic attraction force is generated between the second magnetic member 23 on the third clamping plate 21 and the second magnetic member 23 on the fourth clamping plate 22, so that the third clamping plate 21 and the fourth clamping plate 22 can jointly clamp the laminated assembly A therebetween.

[0051] Specifically in the embodiment, when the first clamping mechanism 10 clamps the laminate assembly A, the area where the first clamping plate 11 contacts the bottom surface A1 of the laminate assembly A is the first area. When the second clamping mechanism 20 clamps the laminate assembly A, the area where the third clamping plate 21 contacts the bottom surface A1 of the laminate assembly A is the second area. The first area and the second area do not overlap with each other. In this way, since the first area and the second area do not overlap, the first clamping plate 11 and the third clamping plate 21 can be simultaneously covered on the bottom surface A1 of the laminate assembly A (that is, the first clamping plate 11 and the third clamping plate 21 will not interfere with each other), so that when switching the clamping mode, the first clamping plate 11 and the second clamping plate 12 can be removed after the third clamping plate 21 and the fourth clamping plate 22 clamp the laminate assembly A, ensuring that the laminate assembly A is always in a clamped state, and further ensuring the stacking accuracy of the laminate assembly A.

[0052] Specifically in the embodiment, when the first clamping mechanism 10 clamps the laminate assembly A, the area where the second clamping plate 12 contacts the top surface A2 of the laminate assembly A is the third area. When the second clamping mechanism 20 clamps the laminate assembly A, the area where the fourth clamping plate 22 contacts the top surface A2 of the laminate assembly A is the fourth area. The third area and the fourth area do not overlap with each other. In this way, since the third area and the fourth area do not overlap, the second clamping plate 12 and the fourth clamping plate 22 can be simultaneously covered on the top surface A2 of the laminate assembly A (that is, the second clamping plate 12 and the fourth clamping plate 22 will not interfere with each other), so that when switching the clamping mode, the second clamping plate 12 can be removed after the third clamping plate 21 and the fourth clamping plate 22 clamp the laminate assembly A, ensuring that the laminate assembly A is always in a clamped state, and further ensuring the stacking accuracy of the laminate assembly A.

[0053] Specifically in the embodiment, the first clamping mechanism 10 further includes a first positioning member 14 (see Figure 2), the first positioning member 14 is installed on the first clamping plate 11. When the first clamping plate 11 and the second clamping plate 12 are respectively covered on the bottom surface A1 and the top surface A2 of the laminate assembly A, the first positioning member 14 positions the second clamping plate 12 on the first clamping plate 11, that is, the first positioning member 14 positions the first clamping plate 11 and the second clamping plate 12, ensuring that the position accuracy of the first clamping plate 11 and the second clamping plate 12 is high, and avoiding the failure to cover the third clamping plate 21 and the fourth clamping plate 22 due to the deviation of the position of the first clamping plate 11 and the second clamping plate 12.

[0054] Optionally, the first positioning member 14 is a positioning pin, and a positioning hole corresponding to the positioning pin is provided on the second clamping plate 12. When the first clamping mechanism 10 clamps the laminate assembly A, the positioning pin is inserted into the positioning hole on the second clamping plate 12, so that the second clamping plate 12 is positioned by the cooperation between the positioning pin and the positioning hole. It is understandable that the number of the first positioning members 14 can be two or more, which is not limited here.

[0055] It should be noted that the first positioning member 14 is not limited to being disposed on the first clamping plate 11. In other embodiments, the first positioning member 14 may also be disposed on the second clamping plate 12, as long as the second clamping plate 12 can be positioned on the first clamping plate 11, which is not limited here.

[0056] Specifically in the embodiment, the second clamping mechanism 20 further includes a second positioning member 24 (see Figure 5 ), the second positioning member 24 is installed on the third clamping plate 21. When the third clamping plate 21 and the fourth clamping plate 22 are respectively covered on the bottom surface A1 and the top surface A2 of the laminate assembly A, the second positioning member 24 positions the fourth clamping plate 22 on the third clamping plate 21, that is, the second positioning member 24 positions the third clamping plate 21 and the fourth clamping plate 22, ensuring that the position accuracy of the third clamping plate 21 and the fourth clamping plate 22 is high, and avoiding the failure to cover the first clamping plate 11 and the second clamping plate 12 due to the deviation of the position of the third clamping plate 21 and the fourth clamping plate 22.

[0057] Optionally, the second positioning member 24 is a positioning pin, and a positioning hole corresponding to the positioning pin is provided on the fourth clamping plate 22. When the second clamping mechanism 20 clamps the laminate assembly A, the positioning pin is inserted into the positioning hole on the fourth clamping plate 22, so that the fourth clamping plate 22 is positioned by the cooperation between the positioning pin and the positioning hole. It is understandable that the number of the second positioning members 24 can be two or more, which is not limited here.

[0058] It should be noted that the second positioning member 24 is not limited to being disposed on the third clamping plate 21. In other embodiments, the second positioning member 24 may also be disposed on the fourth clamping plate 22, as long as the fourth clamping plate 22 can be positioned on the third clamping plate 21, which is not limited here.

[0059] It should be noted that, since the first clamping plate 11 and the second clamping plate 12 need to be positioned by the first positioning member 14, the first clamping plate 11 and the second clamping plate 12 need to extend to an edge of the laminate assembly A and cooperate with the first positioning member 14, so that the first clamping plate 11 and the second clamping plate 12 will cover the corresponding edge of the laminate assembly A. Similarly, since the third clamping plate 21 and the fourth clamping plate 22 need to be positioned by the second positioning member 24, the third clamping plate 21 and the fourth clamping plate 22 need to extend to an edge of the laminate assembly A and cooperate with the second positioning member 24, so that the third clamping plate 21 and the fourth clamping plate 22 will cover the corresponding edge of the laminate assembly A.

[0060] In order to ensure that all edges around the laminate assembly A can be edge-sealed after two edge-sealing processes, in a specific embodiment, the first positioning member 14 and the second positioning member 24 are respectively located on different sides of the laminate assembly A, so that the first clamping plate 11 and the second clamping plate 12 and the third clamping plate 21 and the fourth clamping plate 22 respectively cover different edges of the laminate assembly A. In other words, the first clamping plate 11 and the second clamping plate 12 cover one side edge of the laminate assembly A, and the third clamping plate 21 and the fourth clamping plate 22 cover the other side edge of the laminate assembly A.

[0061] In this way, when the first clamping mechanism 10 clamps the laminate assembly A, the edges of the laminate assembly A other than the edges blocked by the first clamping plate 11 and the second clamping plate 12 are edge-sealed. When the second clamping mechanism 20 clamps the laminate assembly A, the edges of the laminate assembly A previously blocked by the first clamping plate 11 and the second clamping plate 12 are edge-sealed, thereby ensuring that all edges around the laminate assembly A are edge-sealed after two edge-sealing processes, when the laminate assembly A is clamped by the first clamping mechanism 10 and when the laminate assembly A is clamped by the second clamping mechanism 20.

[0062] Optionally, the first positioning member 14 and the second positioning member 24 are respectively located on both sides of the laminate assembly A in the first direction X1, so that the first clamping plate 11 and the second clamping plate 12 cover one side edge of the laminate assembly A in the first direction X1, and the third clamping plate 21 and the fourth clamping plate 22 cover the other side edge of the laminate assembly A in the first direction X1 (such as Figure 2 and Figure 5 As shown, the first clamping plate 11 and the second clamping plate 12 cover the first edge a1 of the laminate assembly A, and the third clamping plate 21 and the fourth clamping plate 22 cover the third edge a3 of the laminate assembly A).

[0063] Please continue to see Figure 7 and Figure 8As shown, in the embodiment of the present application, the tooling for clamping the laminate assembly A also includes a switching mechanism (not shown). The switching mechanism is used to remove the second clamping plate 12 after the second clamping mechanism 20 clamps the laminate assembly A, that is, the state of clamping the laminate assembly A by the first clamping mechanism 10 is switched to the state of clamping the laminate assembly A by the second clamping mechanism 20. The switching mechanism includes a support platform 31 and a lifting unit 32. The support platform 31 is used to carry the first clamping plate 11 and the third clamping plate 21, and the lifting unit 32 is used to lift the second clamping plate 12 covered on the top surface A2 of the laminate assembly A, so that the second clamping plate 12 is separated from the laminate assembly A, thereby realizing the unloading of the second clamping plate 12.

[0064] Thus, the third clamping plate 21 is placed on the support platform 31, and after the lamination assembly A completes the first edge sealing process (i.e., Figure 2 In the illustrated embodiment, after edge banding treatment is performed on the second edge a2, the third edge a3 and the fourth edge a4 of the laminate assembly A, the first clamp plate 11, the second clamp plate 12 and the laminate assembly A therebetween are transferred as a whole to the support platform 31. At this time, the first clamp plate 11 and the third clamp plate 21 are supported on the support platform 31, the laminate assembly A is located on the first clamp plate 11 and the third clamp plate 21, and the second clamp plate 12 is located on the top surface A2 of the laminate assembly A. Then, the fourth clamp plate 22 is covered on the top surface A2 of the laminate assembly A, so that the third clamp plate 21 and the fourth clamp plate 22 clamp the laminate assembly A under the magnetic attraction of the second magnetic attraction member 23. Then, the lifting unit 32 lifts the second clamp plate 12 so that the second clamp plate 12 is separated from the laminate assembly A. At this time, the laminate assembly A is clamped by the third clamp plate 21 and the fourth clamp plate 22. Then, the third clamping plate 21, the fourth clamping plate 22 and the laminate assembly A therebetween are transferred as a whole to the edge banding station, where the laminate assembly A is subjected to a second edge banding process, that is, the edge of the laminate assembly A previously blocked by the first clamping plate 11 and the second clamping plate 12 (i.e., Figure 5 In the embodiment shown, the first edge a1) is sealed.

[0065] Specifically in the embodiment, the lifting unit 32 includes a first driving component 322 and a lifting block 321 installed at the driving end of the first driving component 322. The first driving component 322 is used to drive the lifting block 321 to move to be matched with or separated from the second clamping plate 12. The first driving component 322 is also used to drive the lifting block 321 to perform a lifting movement when the lifting block 321 is matched with the second clamping plate 12, so that the lifting block 321 lifts the second clamping plate 12. In this way, when the second clamping plate 12 needs to be removed, the first driving component 322 first drives the lifting block 321 to move toward the second clamping plate 12 until the lifting block 321 is matched with the second clamping plate 12; then the first driving component 322 drives the lifting block 321 to move upward, thereby driving the second clamping plate 12 to overcome the magnetic attraction of the first magnetic attraction member 13 and move upward, so that the second clamping plate 12 is separated from the lamination assembly A.

[0066] Specifically, the switching mechanism also includes a base 40, and the support platform 31 is fixedly mounted on the base 40. The first driving assembly 322 includes a first moving seat 3221, a first translation driving member 3223 and a first lifting driving member 3225. The first moving seat 3221 is movably connected to the base 40. The first translation driving member 3223 is mounted on the base 40 and is drivingly connected to the first moving seat 3221, so that the first translation driving member 3223 can drive the first moving seat 3221 to move relative to the base 40. The first lifting driving member 3225 is mounted on the first moving seat 3221, so that the first lifting driving member 3225 can move relative to the base 40 with the first moving seat 3221. The lifting block 321 is mounted on the driving end of the first lifting driving member 3225, so that the first lifting driving member 3225 can drive the lifting block 321 to rise or fall.

[0067] Thus, when the second clamping plate 12 needs to be removed, the first translation driver 3223 first drives the first movable seat 3221 to move relative to the base 40, thereby driving the lifting block 321 to gradually move closer to the second clamping plate 12 until the lifting block 321 is matched with the second clamping plate 12. Then, the first lifting driver 3225 drives the lifting block 321 to rise, so that the lifting block 321 drives the second clamping plate 12 to rise, so that the second clamping plate 12 is separated from the lamination assembly A, that is, the second clamping plate 12 is unloaded. Optionally, both the first translation driver 3223 and the first lifting driver 3225 can be cylinders.

[0068] Optionally, the first movable seat 3221 can be installed on the base 40 via a guide structure such as a slide rail and a slider, so that the guide structure can be used to guide the movement of the first movable seat 3221 relative to the base 40, ensuring that the first movable seat 3221 can drive the lifting block 321 to accurately mate with or separate from the second clamping plate 12.

[0069] Furthermore, the second clamping plate 12 has a matching portion (not shown) for matching with the lifting block 321, so that the lifting block 321 can match or separate with the matching portion on the second clamping plate 12. When the lifting block 321 matches with the matching portion on the second clamping plate 12, the second clamping plate 12 can rise or fall together with the lifting block 321. Optionally, the matching portion can be a matching groove.

[0070] Optionally, the number of the lifting units 32 may be two, and the two lifting units 32 are respectively arranged on opposite sides of the support platform 31, so that the second clamping plate 12 is lifted simultaneously by the two lifting units 32, ensuring that the second clamping plate 12 can be stably and reliably separated from the lamination assembly A. Of course, in other embodiments, more lifting units 32 may be provided, as long as the second clamping plate 12 can be stably lifted, which is not limited here.

[0071] Specifically in the embodiment, the switching mechanism further includes a first pressing unit 33, which can controllably press the laminate assembly A onto the first clamping plate 11. In this way, before unloading the second clamping plate 12, the laminate assembly A is pressed onto the first clamping plate 11 by the first pressing unit 33, so that when the second clamping plate 12 is subsequently lifted by the lifting unit 32, the laminate assembly A will not move with the second clamping plate 12.

[0072] Further, the first pressing unit 33 includes a second driving assembly 332 and a first pressing block 331 installed at the driving end of the second driving assembly 332. The second driving assembly 332 is used to drive the first pressing block 331 to move above the laminate assembly A. The second driving assembly 332 is also used to drive the first pressing block 331 to press down when the first pressing block 331 is above the laminate assembly A until the first pressing block 331 presses the laminate assembly A onto the first clamping plate 11.

[0073] Specifically, the second driving assembly 332 includes a second moving seat 3321, a second translation driving member 3323 and a second lifting driving member 3325. The second moving seat 3321 is movably connected to the base 40. The second translation driving member 3323 is installed on the base 40 and is drivingly connected to the second moving seat 3321, so that the second translation driving member 3323 can drive the second moving seat 3321 to move relative to the base 40. The second lifting driving member 3325 is installed on the second moving seat 3321, so that the second lifting driving member 3325 can move relative to the base 40 with the second moving seat 3321. The first pressing block 331 is installed at the driving end of the second lifting driving member 3325, so that the second lifting driving member 3325 can drive the first pressing block 331 to rise or fall. Optionally, both the second translation driving member 3323 and the second lifting driving member 3325 can use cylinders.

[0074] Optionally, the second movable seat 3321 can be installed on the base 40 via a guide structure such as a slide rail and a slider, so that the guide structure can be used to guide the movement of the second movable seat 3321 relative to the base 40, ensuring that the second movable seat 3321 can drive the first clamping block 331 to accurately enter or exit the upper position of the stacking assembly A.

[0075] Specifically in the embodiment, the switching mechanism further includes a second pressing unit 34, which can controllably press the fourth clamping plate 22 against the top surface A2 of the laminate assembly A. In this way, before unloading the second clamping plate 12, the fourth clamping plate 22 is pressed against the top surface A2 of the laminate assembly A by the second pressing unit 34, so that when the second clamping plate 12 is subsequently lifted by the lifting unit 32, the fourth clamping plate 22 and the laminate assembly A will not move with the second clamping plate 12.

[0076] Further, the second pressing unit 34 includes a third driving assembly 342 and a second pressing block 341 installed at the driving end of the third driving assembly 342. The third driving assembly 342 is used to drive the second pressing block 341 to move above the fourth clamping plate 22. The third driving assembly 342 is also used to drive the second pressing block 341 to press down when the second pressing block 341 is above the fourth clamping plate 22, until the second pressing block 341 presses the fourth clamping plate 22 onto the top surface A2 of the lamination assembly A.

[0077] Specifically, the third driving assembly 342 includes a third moving seat, a third translation driving member 3423 and a third lifting driving member. The third moving seat is movably connected to the base 40. The third translation driving member 3423 is installed on the base 40 and is drivingly connected to the third moving seat, so that the third translation driving member 3423 can drive the third moving seat to move relative to the base 40. The third lifting driving member is installed on the third moving seat, so that the third lifting driving member can move relative to the base 40 with the third moving seat. The second clamping block 341 is installed at the driving end of the third lifting driving member, so that the third lifting driving member can drive the second clamping block 341 to rise or fall. Optionally, both the third translation driving member 3423 and the third lifting driving member can adopt cylinders.

[0078] Optionally, the third movable seat can be installed on the base 40 via a guide structure such as a slide rail and a slider, so that the guide structure can be used to guide the movement of the third movable seat relative to the base 40, ensuring that the third movable seat can drive the second clamping block 341 to accurately enter or exit the upper position of the fourth clamping plate 22.

[0079] Specific to Figure 7 and Figure 8In the illustrated embodiment, two lifting units 32 are provided, and the two lifting units 32 are respectively arranged on both sides of the support platform 31 in the second direction X2. The first pressing unit 33 and the second pressing unit 34 are respectively arranged on both sides of the support platform 31 in the first direction X1.

[0080] The working process of the tooling for clamping the lamination assembly A is described below in conjunction with the accompanying drawings:

[0081] First, the first clamping plate 11 is placed on a lamination table, and lamination materials are stacked on the first clamping plate 11 to form a lamination assembly A.

[0082] Then, the second clamping plate 12 is placed on the top surface A2 of the laminate assembly A (at this time, the first clamping plate 11 and the second clamping plate 12 are positioned by the first positioning member 14), so that the first clamping plate 11 and the second clamping plate 12 jointly clamp the laminate assembly A under the action of the magnetic attraction provided by the first magnetic attraction member 13. At this time, the first edge a1 of the laminate assembly A is blocked by the first clamping plate 11 and the second clamping plate 12, and the second edge a2, the third edge a3 and the fourth edge a4 of the laminate assembly A are exposed.

[0083] Then, the first clamping plate 11, the second clamping plate 12 and the laminate assembly A therebetween are transferred as a whole to the edge banding station, and the second edge a2, the third edge a3 and the fourth edge a4 of the laminate assembly A are edge banded at the edge banding station.

[0084] Then, the third clamping plate 21 is placed on the support platform 31, and the first clamping plate 11, the second clamping plate 12 and the laminate assembly A therebetween are transferred as a whole to the support platform 31. At this time, the first clamping plate 11 and the third clamping plate 21 are covered on the bottom surface A1 of the laminate assembly A, and the second clamping plate 12 is covered on the top surface A2 of the laminate assembly A.

[0085] Then, the fourth clamp 22 is covered on the top surface A2 of the stacking assembly A (at this time, the third clamp 21 and the fourth clamp 22 are positioned using the second positioning member 24), so that the third clamp 21 and the fourth clamp 22 jointly clamp the stacking assembly A under the action of the magnetic force provided by the second magnetic member 23.

[0086] Then, the lamination assembly A is pressed onto the first clamping plate 11 by using the first clamping unit 33 , and the fourth clamping plate 22 is pressed onto the top surface A2 of the lamination assembly A by using the second clamping unit 34 .

[0087] Then, the second clamping plate 12 is lifted by the lifting unit 32 to separate the second clamping plate 12 from the lamination assembly A. Since the distance between the second clamping plate 12 and the first clamping plate 11 is far enough, the magnetic attraction force generated by the first magnetic attraction member 13 is small enough or does not generate any magnetic attraction force.

[0088] Then, the first clamping unit 33 releases the laminate assembly A, the second clamping unit 34 releases the fourth clamping plate 22, and the third clamping plate 21, the fourth clamping plate 22 and the laminate assembly A therebetween are transferred as a whole to the edge banding station (at this time, the third edge a3 of the laminate assembly A is blocked by the third clamping plate 21 and the fourth clamping plate 22, and the first edge a1, the second edge a2 and the fourth edge a4 of the laminate assembly A are exposed). The first edge a1 of the laminate assembly A is edge banded at the edge banding station. At this time, the purpose of edge banding all the edges around the laminate assembly A is achieved.

[0089] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0090] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
