Description

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.

[0004] A tool for clamping a lamination assembly, comprising:

[0005] A bottom plate, used for carrying the lamination assembly;

[0006] The first clamping plate and the second clamping plate can both be covered on a side of the lamination assembly away from the bottom plate; and

[0007] A magnetic attraction member, wherein the magnetic attraction member is arranged on the bottom plate, or the magnetic attraction member is arranged on the first clamping plate and the second clamping plate; under the action of the magnetic attraction force generated by the magnetic attraction member, the first clamping plate or the second clamping plate and the bottom plate jointly clamp the laminated assembly;

[0008] Wherein, when the first clamping plate cover is arranged on the lamination assembly, the first clamping plate covers a part of the edge of the lamination assembly; when the second clamping plate cover is arranged on the lamination assembly, the second clamping plate covers another part of the edge of the lamination assembly.

[0009] In one embodiment, the area where the first clamping plate contacts the surface of the lamination assembly facing away from the base plate is the first area, and the area where the second clamping plate contacts the surface of the lamination assembly facing away from the base plate is the second area, and the first area and the second area do not overlap each other.

[0010] In one embodiment, the tooling further includes a first positioning member, which is mounted on one of the base plate and the first clamping plate; when the first clamping plate is covered on the stacking assembly, the first positioning member positions the first clamping plate on the base plate.

[0011] In one embodiment, the tooling further comprises a second positioning member, wherein the second positioning member is mounted on one of the base plate and the second clamping plate; when the second clamping plate is covered on the lamination assembly, the second positioning member positions the second clamping plate on the base plate.

[0012] 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 respectively cover different edges of the laminate assembly.

[0013] In one embodiment, the first positioning member and the second positioning member are respectively located on two sides of the stacking assembly in the first direction, so that the first clamping plate and the second clamping plate respectively cover two side edges of the stacking assembly in the first direction.

[0014] In one embodiment, the tooling further includes a switching mechanism, and the switching mechanism includes a support platform and a lifting unit;

[0015] The support platform is used to support the base plate, and the lifting unit is used to lift the first clamping plate that covers the side of the lamination assembly away from the base plate, so that the first clamping plate is separated from the lamination assembly.

[0016] 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 first clamping plate.

[0017] In one of the embodiments, the switching mechanism further comprises a first pressing unit arranged corresponding to the support platform, and the first pressing unit can controllably press the lamination assembly onto the base plate.

[0018] In one of the embodiments, the switching mechanism further comprises a second pressing unit arranged corresponding to the support platform, and the second pressing unit can controllably press the second clamping plate onto the lamination assembly.

[0019] The above-mentioned tooling for clamping the laminated assembly, when actually used, first places the base plate on the lamination table, and stacks the laminated material (such as pole pieces) on the base plate to form a laminated assembly. After the stacking is completed, the first clamping plate cover is set on the top of the laminated assembly (that is, the cover is set on the side of the laminated assembly away from the base plate), so that the first clamping plate and the base plate clamp the laminated assembly between the two under the action of the magnetic attraction generated by the magnetic suction part, thereby achieving the clamping of the laminated assembly. At this time, the first clamping plate does not cover all the edges of the laminated assembly, that is, part of the edges of the laminated assembly are in an exposed state. Then, the edges of the laminated assembly in the exposed state are edge-sealed. Then, the second clamping plate cover is set on the side of the laminated assembly away from the base plate, and the first clamping plate is removed, so that the second clamping plate and the base plate clamp the laminated assembly between the two under the action of the magnetic attraction generated by the magnetic suction part, that is, the laminated assembly is still in a clamped state. At this time, the edges of the laminated assembly that have not yet been edge-sealed are in an exposed state. Then, the edge of the lamination assembly that has not been subjected to the edge sealing treatment is subjected to the edge sealing treatment, thereby achieving the purpose of edge sealing on all edges around the lamination assembly. Finally, the second clamping plate is removed, and the lamination assembly on the bottom plate is taken out.

[0020] In this way, during the transfer and edge sealing process of the stacking assembly, the stacking assembly is clamped by using the first clamping plate or the second clamping plate and the bottom plate, that is, the stacking assembly always remains in a clamped state, thereby avoiding positional offset between the layers of material of the stacking assembly, greatly improving the stacking accuracy of the stacking assembly, and further facilitating improving the quality of the solid battery containing the stacking assembly.

[0034] See also Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, an embodiment of the utility model provides a tool for clamping a laminate assembly A, including a base plate 10, a first clamping plate 20, a second clamping plate 30 and a magnetic member 40. The base plate 10 is used to carry the laminate assembly A. In actual use, the base plate 10 is placed on a lamination table (not shown), and then the laminate material is stacked on the base plate 10 to form the laminate assembly A. The first clamping plate 20 and the second clamping plate 30 can be selectively covered on the side of the laminate assembly A away from the base plate 10. The magnetic member 40 is arranged on the base plate 10. Under the action of the magnetic attraction force generated by the magnetic member 40, the first clamping plate 20 or the second clamping plate 30 and the base plate 10 jointly clamp the laminate assembly A therebetween, thereby achieving the clamping of the laminate assembly A. When the first clamping plate 20 is disposed on the side of the laminate assembly A away from the bottom plate 10, the first clamping plate 20 blocks part of the edge of the laminate assembly A, so that the blocked edge of the laminate assembly A cannot be edge-sealed at this time, and only the edge of the laminate assembly A in an exposed state (i.e., not blocked) can be edge-sealed. When the second clamping plate 30 is disposed on the side of the laminate assembly A away from the bottom plate 10, the second clamping plate 30 blocks another part of the edge of the laminate assembly A, so that the unblocked edge of the laminate assembly A can be edge-sealed at this time. In other words, the first clamping plate 20 and the second clamping plate 30 respectively block different edges of the laminate assembly A.

[0035] It should be noted that the magnetic member 40 is not limited to being disposed on the bottom plate 10. In other embodiments, see Figure 1 and Figure 2 As shown, the magnetic attraction member 40 can also be arranged on the first clamping plate 20 and the second clamping plate 30, that is, the first clamping plate 20 and the second clamping plate 30 are both provided with the magnetic attraction member 40. When the first clamping plate 20 is covered on the side of the laminate assembly A away from the bottom plate 10, the magnetic attraction member 40 on the first clamping plate 20 generates a magnetic attraction force to adsorb the bottom plate 10, so that the first clamping plate 20 and the bottom plate 10 jointly clamp the laminate assembly A between the two, thereby achieving the clamping of the laminate assembly A. When the second clamping plate 30 is covered on the side of the laminate assembly A away from the bottom plate 10, the magnetic attraction member 40 on the second clamping plate 30 generates a magnetic attraction force to adsorb the bottom plate 10, so that the second clamping plate 30 and the bottom plate 10 jointly clamp the laminate assembly A between the two, thereby achieving the clamping of the laminate assembly A. Optionally, the magnetic attraction member 40 can be a magnet.

[0036] 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.

[0037] When the tooling for clamping the stack assembly A is actually used, the bottom plate 10 is first placed on the stacking table, and the stacking materials (such as pole pieces) are stacked on the bottom plate 10 to form the stack assembly A. After the stacking is completed, the first clamping plate 20 is placed on the top of the stack assembly A (that is, the side of the stack assembly A facing away from the bottom plate 10), so that the first clamping plate 20 and the bottom plate 10 are clamped together by the magnetic attraction force generated by the magnetic attraction member 40, thereby achieving the clamping of the stack assembly A (such as Figure 3 and Figure 4 As shown). At this time, the first clamping plate 20 does not cover all the edges of the laminate assembly A, that is, part of the edges of the laminate assembly A are exposed. Then, the edges of the laminate assembly A that are in an exposed state are edge-sealed. Then, the second clamping plate 30 is placed on the side of the laminate assembly A away from the bottom plate 10, and the first clamping plate 20 is removed, so that the second clamping plate 30 and the bottom plate 10 clamp the laminate assembly A therebetween under the action of the magnetic attraction generated by the magnetic attraction member 40, that is, the laminate assembly A is still in a clamped state (as shown). Figure 6 and Figure 7 ). At this time, the edge of the laminate assembly A that has not been edge-sealed is exposed. Then, the edge of the laminate assembly A that has not been edge-sealed is edge-sealed, so that the edge of all edges around the laminate assembly A is edge-sealed. Finally, the second clamping plate 30 is removed, and the laminate assembly A on the bottom plate 10 is taken out.

[0038] In this way, during the transfer and edge sealing process of the stack assembly A, the stack assembly A is clamped by using the first clamp 20 or the second clamp 30 and the base plate 10, that is, the stack assembly A always remains 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.

[0039] Please note that, see Figure 3 and Figure 4 When the first clamping plate 20 is placed on the side of the laminate assembly A away from the bottom plate 10, 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.

[0040] See also Figure 6 and Figure 7 When the second clamping plate 30 is placed on the side of the laminate assembly A away from the bottom plate 10, the edge of the laminate assembly A blocked by the second clamping plate 30 belongs to the second edge (i.e., the edge that has been edge-sealed). At this time, the first edge is exposed, so the first edge can be edge-sealed, thereby achieving edge-sealing of all edges around the laminate assembly A through two edge-sealing processes.

[0041] Specific to Figure 4 and Figure 7 In 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 plate 20 is placed on the side of the lamination assembly A away from the bottom plate 10 (see Figure 4 ), the first clamping plate 20 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 are edge-sealed.

[0042] When the second clamping plate 30 is placed on the side of the lamination assembly A away from the bottom plate 10 (see Figure 7), the second clamping plate 30 covers the third edge a3 of the laminate assembly A, but does not cover 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 is edge-sealed. In this way, after two edge-sealing processes, the edge sealing of all edges around the laminate assembly A is completed.

[0043] 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.

[0044] Please continue to see Figure 4 and Figure 7 As shown, in the embodiment, when the first clamping plate 20 is disposed on the side of the lamination assembly A away from the bottom plate 10 (such as Figure 3 and Figure 4 The area where the first clamping plate 20 contacts the surface of the side of the lamination assembly A facing away from the bottom plate 10 is the first area A1 (see Figure 7 When the second clamping plate 30 is placed on the side of the lamination assembly A away from the bottom plate 10 (such as Figure 6 and Figure 7 The area where the second clamping plate 30 contacts the surface of the side of the lamination assembly A facing away from the bottom plate 10 is the second area A2 (see Figure 4 ). The first area A1 and the second area A2 do not overlap each other. In this way, since the first area A1 and the second area A2 do not overlap, the first clamping plate 20 and the second clamping plate 30 can be simultaneously covered on the surface of the side of the stacking assembly A away from the bottom plate 10, so that when switching the clamping mode, the first clamping plate 20 can be removed after the second clamping plate 30 and the bottom plate 10 clamp the stacking assembly A, ensuring that the stacking assembly A is always in a clamped state, further ensuring the stacking accuracy of the stacking assembly A.

[0045] See also Figures 3 to 7 Specifically, in the embodiment, the tooling for clamping the lamination assembly A further includes a first positioning member 50. The first positioning member 50 is mounted on the base plate 10. When the first clamping plate 20 is covered on the side of the lamination assembly A away from the base plate 10, the first positioning member 50 positions the first clamping plate 20 on the base plate 10. In this way, the first positioning member 50 is used to position the first clamping plate 20, ensuring that the position accuracy of the first clamping plate 20 is high, and avoiding the failure to cover the second clamping plate 30 due to the deviation of the position of the first clamping plate 20.

[0046] Optionally, the first positioning member 50 is a positioning pin, and a positioning hole corresponding to the positioning pin is provided on the first clamping plate 20. When the first clamping plate 20 is covered on the side of the stacking assembly A away from the bottom plate 10, the positioning pin is inserted into the positioning hole on the first clamping plate 20, so that the first clamping plate 20 is positioned by the cooperation between the positioning pin and the positioning hole. It can be understood that the number of the first positioning members 50 can be two or more, which is not limited here.

[0047] It should be noted that the first positioning member 50 is not limited to being disposed on the bottom plate 10. In other embodiments, the first positioning member 50 may also be disposed on the first clamping plate 20, as long as the first clamping plate 20 can be positioned on the bottom plate 10, which is not limited here.

[0048] Furthermore, the tooling for clamping the lamination assembly A further includes a second positioning member 60, which is mounted on the bottom plate 10. When the second clamping plate 30 is covered on the lamination assembly A, the second positioning member 60 positions the second clamping plate 30 on the bottom plate 10. In this way, the second clamping plate 30 is positioned by the second positioning member 60, ensuring that the position accuracy of the second clamping plate 30 is better, and avoiding interference with the first clamping plate 20 when the second clamping plate 30 is covered due to deviation in the position of the second clamping plate 30.

[0049] Optionally, the second positioning member 60 is a positioning pin, and a positioning hole corresponding to the positioning pin is provided on the second clamping plate 30. When the second clamping plate 30 is covered on the side of the laminate assembly A away from the bottom plate 10, the positioning pin is inserted into the positioning hole on the second clamping plate 30, so that the second clamping plate 30 is positioned by the cooperation between the positioning pin and the positioning hole. It can be understood that the number of the second positioning members 60 can be two or more, which is not limited here.

[0050] It should be noted that the second positioning member 60 is not limited to being disposed on the bottom plate 10. In other embodiments, the second positioning member 60 may also be disposed on the second clamping plate 30, as long as the second clamping plate 30 can be positioned on the bottom plate 10, which is not limited here.

[0051] It should be noted that, since the first clamping plate 20 needs to be positioned by the first positioning member 50, the first clamping plate 20 needs to extend to the corresponding edge of the laminate assembly A and cooperate with the first positioning member 50, so that the first clamping plate 20 will cover the corresponding edge of the laminate assembly A. In order to ensure that all edges around the laminate assembly A can be sealed after two edge sealing processes, in a specific embodiment, the first positioning member 50 and the second positioning member 60 are respectively located on different sides of the laminate assembly A, so that the first clamping plate 20 and the second clamping plate 30 respectively cover different edges of the laminate assembly A.

[0052] In this way, when the first clamping plate 20 and the bottom plate 10 clamp the laminate assembly A, the edges of the laminate assembly A other than the edges blocked by the first clamping plate 20 are edge-sealed. When the second clamping plate 30 and the bottom plate 10 clamp the laminate assembly A, the edges of the laminate assembly A previously blocked by the first clamping plate 20 are edge-sealed, thereby ensuring that all edges around the laminate assembly A are edge-sealed after two edge-sealing processes, when the first clamping plate 20 and the bottom plate 10 clamp the laminate assembly A and when the second clamping plate 30 and the bottom plate 10 clamp the laminate assembly A.

[0053] Optionally, the first positioning member 50 and the second positioning member 60 are respectively located on both sides of the stack assembly A in the first direction X1, so that the first clamping plate 20 and the second clamping plate 30 respectively cover the two side edges of the stack assembly A in the first direction X1 (that is, the first clamping plate 20 and the second clamping plate 30 respectively cover the first edge a1 and the third edge a3 of the stack assembly A).

[0054] Please continue to see Figure 1 and Figure 2 In the embodiment of the present application, the tooling for clamping the lamination assembly A further includes a switching mechanism (not shown in the figure), which is used to remove the first clamping plate 20 after the second clamping plate 30 is covered on the lamination assembly A. The switching mechanism includes a support platform 71 and a lifting unit 72. The support platform 71 is used to carry the bottom plate 10, and the lifting unit 72 is used to lift the first clamping plate 20 that is covered on the side of the lamination assembly A away from the bottom plate 10, so that the first clamping plate 20 is separated from the lamination assembly A, thereby realizing the unloading of the first clamping plate 20.

[0055] In this way, after the stacking assembly A completes the first edge-banding process (i.e., after the second edge a2, the third edge a3, and the fourth edge a4 of the stacking assembly A are edge-banded), the base plate 10, the first clamping plate 20, and the stacking assembly A therebetween are transferred as a whole to the support platform 71. At this time, the base plate 10 is supported on the support platform 71, the stacking assembly A is located above the base plate 10, and the first clamping plate 20 is located above the stacking assembly A. Then, the second clamping plate 30 is covered on the stacking assembly A, so that the second clamping plate 30 and the base plate 10 clamp the stacking assembly A under the action of the magnetic suction member 40. Then, the lifting unit 72 lifts the first clamping plate 20, so that the first clamping plate 20 is separated from the stacking assembly A. At this time, the stacking assembly A is clamped by the base plate 10 and the second clamping plate 30. Then, the stacking assembly A is subjected to the second edge-banding process, i.e., the edge of the stacking assembly A previously blocked by the first clamping plate 20 (i.e., the first edge a1) is edge-banded.

[0056] Specifically in the embodiment, the lifting unit 72 includes a first driving assembly 722 and a lifting block 721 installed at the driving end of the first driving assembly 722. The first driving assembly 722 is used to drive the lifting block 721 to move to be matched with or separated from the first clamping plate 20. The first driving assembly 722 is also used to drive the lifting block 721 to perform a lifting movement when the lifting block 721 is matched with the first clamping plate 20, so that the lifting block 721 lifts the first clamping plate 20. In this way, when the first clamping plate 20 needs to be removed, the first driving assembly 722 first drives the lifting block 721 to move toward the first clamping plate 20 until the lifting block 721 is matched with the first clamping plate 20; then the first driving assembly 722 drives the lifting block 721 to move upward, thereby driving the first clamping plate 20 to overcome the magnetic attraction of the magnetic attraction member 40 and move upward, so that the first clamping plate 20 is separated from the lamination assembly A.

[0057] Specifically, the switching mechanism also includes a base 80, and the support platform 71 is fixedly mounted on the base 80. The first driving assembly 722 includes a first moving seat 7221, a first translation driving member 7223 and a first lifting driving member 7225. The first moving seat 7221 is movably connected to the base 80. The first translation driving member 7223 is mounted on the base 80 and is drivingly connected to the first moving seat 7221, so that the first translation driving member 7223 can drive the first moving seat 7221 to move relative to the base 80. The first lifting driving member 7225 is mounted on the first moving seat 7221, so that the first lifting driving member 7225 can move relative to the base 80 with the first moving seat 7221. The lifting block 721 is mounted on the driving end of the first lifting driving member 7225, so that the first lifting driving member 7225 can drive the lifting block 721 to rise or fall.

[0058] Thus, when the first clamping plate 20 needs to be unloaded, the first translation driver 7223 first drives the first moving seat 7221 to move relative to the base 80, thereby driving the lifting block 721 to gradually move closer to the first clamping plate 20 until the lifting block 721 is matched with the first clamping plate 20. Then, the first lifting driver 7225 drives the lifting block 721 to rise, so that the lifting block 721 drives the first clamping plate 20 to rise, so that the first clamping plate 20 is separated from the lamination assembly A, that is, the first clamping plate 20 is unloaded. Optionally, both the first translation driver 7223 and the first lifting driver 7225 can be cylinders.

[0059] Optionally, the first movable seat 7221 can be installed on the base 80 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 7221 relative to the base 80, ensuring that the first movable seat 7221 can drive the lifting block 721 to accurately mate with or separate from the first clamping plate 20.

[0060] Furthermore, the first clamping plate 20 has a matching portion (not shown) for matching with the lifting block 721, so that the lifting block 721 can match or separate with the matching portion on the first clamping plate 20. When the lifting block 721 matches with the matching portion on the first clamping plate 20, the first clamping plate 20 can rise or fall together with the lifting block 721. Optionally, the matching portion can be a matching groove.

[0061] Optionally, the number of the lifting units 72 may be two, and the two lifting units 72 are respectively arranged on opposite sides of the support platform 71, so that the first clamping plate 20 is lifted simultaneously by the two lifting units 72, ensuring that the first clamping plate 20 can be stably and reliably separated from the lamination assembly A. Of course, in other embodiments, more lifting units 72 may be provided, as long as the first clamping plate 20 can be stably lifted, which is not limited here.

[0062] Specifically in the embodiment, the switching mechanism further includes a first pressing unit 73, which can controllably press the laminate assembly A onto the bottom plate 10. In this way, before unloading the first clamping plate 20, the laminate assembly A is pressed onto the bottom plate 10 by the first pressing unit 73, so that when the first clamping plate 20 is subsequently lifted by the lifting unit 72, the laminate assembly A will not move with the first clamping plate 20.

[0063] Further, the first pressing unit 73 includes a second driving assembly 732 and a first pressing block 731 installed at the driving end of the second driving assembly 732. The second driving assembly 732 is used to drive the first pressing block 731 to move above the lamination assembly A. The second driving assembly 732 is also used to drive the first pressing block 731 to press down when the first pressing block 731 is above the lamination assembly A until the first pressing block 731 presses the lamination assembly A onto the bottom plate 10.

[0064] Specifically, the second driving assembly 732 includes a second moving seat 7321, a second translation driving member 7323 and a second lifting driving member 7325. The second moving seat 7321 is movably connected to the base 80. The second translation driving member 7323 is installed on the base 80 and is drivingly connected to the second moving seat 7321, so that the second translation driving member 7323 can drive the second moving seat 7321 to move relative to the base 80. The second lifting driving member 7325 is installed on the second moving seat 7321, so that the second lifting driving member 7325 can move relative to the base 80 with the second moving seat 7321. The first pressing block 731 is installed at the driving end of the second lifting driving member 7325, so that the second lifting driving member 7325 can drive the first pressing block 731 to rise or fall. Optionally, both the second translation driving member 7323 and the second lifting driving member 7325 can use cylinders.

[0065] Optionally, the second movable seat 7321 can be installed on the base 80 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 7321 relative to the base 80, ensuring that the second movable seat 7321 can drive the first clamping block 731 to accurately enter or exit the upper position of the stacking assembly A.

[0066] Specifically in the embodiment, the switching mechanism further includes a second pressing unit 74, which can controllably press the second clamping plate 30 onto the laminate assembly A. In this way, before unloading the first clamping plate 20, the second clamping unit 74 is used to press the second clamping plate 30 onto the laminate assembly A, so that when the first clamping plate 20 is subsequently lifted by the lifting unit 72, the second clamping plate 30 and the laminate assembly A will not move with the first clamping plate 20.

[0067] Further, the second pressing unit 74 includes a third driving assembly 742 and a second pressing block 741 installed at the driving end of the third driving assembly 742. The third driving assembly 742 is used to drive the second pressing block 741 to move above the second clamping plate 30. The third driving assembly 742 is also used to drive the second pressing block 741 to press down when the second pressing block 741 is above the second clamping plate 30, until the second pressing block 741 presses the second clamping plate 30 onto the lamination assembly A.

[0068] Specifically, the third driving assembly 742 includes a third moving seat, a third translation driving member 7423 and a third lifting driving member. The third moving seat is movably connected to the base 80. The third translation driving member 7423 is installed on the base 80 and is drivingly connected to the third moving seat, so that the third translation driving member 7423 can drive the third moving seat to move relative to the base 80. 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 80 with the third moving seat. The second clamping block 741 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 741 to rise or fall. Optionally, both the third translation driving member 7423 and the third lifting driving member can adopt cylinders.

[0069] Optionally, the third movable seat can be installed on the base 80 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 80, ensuring that the third movable seat can drive the second clamping block 741 to accurately enter or exit the upper position of the second clamping plate 30.

[0070] Specific to Figure 1 and Figure 2In the illustrated embodiment, two lifting units 72 are provided, and the two lifting units 72 are respectively arranged on both sides of the support platform 71 in the second direction X2. The first pressing unit 73 and the second pressing unit 74 are respectively arranged on both sides of the support platform 71 in the first direction X1.

[0071] The working process of the tooling for clamping the lamination assembly A is described below in conjunction with the accompanying drawings:

[0072] First, the base plate 10 is placed on a lamination table, and lamination materials are stacked on the base plate 10 to form a lamination assembly A.

[0073] Then, the first clamping plate 20 is placed on the laminate assembly A (at this time, the first positioning member 50 is used to position the first clamping plate 20), so that the first clamping plate 20 and the bottom plate 10 clamp the laminate assembly A (such as Figure 3 and Figure 4 At this time, the first edge a1 of the laminate assembly A is blocked by the first clamping plate 20, and the second edge a2, the third edge a3 and the fourth edge a4 of the laminate assembly A are exposed.

[0074] Then, the bottom plate 10, the first clamping plate 20 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.

[0075] Then, the base plate 10 , the first clamping plate 20 and the lamination assembly A therebetween are transferred as a whole to the support platform 71 .

[0076] Then, the second clamping plate 30 is placed on the lamination assembly A (at this time, the second clamping plate 30 is positioned by the second positioning member 60 ), so that the second clamping plate 30 and the base plate 10 clamp the lamination assembly A under the action of the magnetic attraction provided by the magnetic attraction member 40 .

[0077] Then, the lamination assembly A is pressed onto the base plate 10 by using the first pressing unit 73 , and the second clamping plate 30 is pressed onto the lamination assembly A by using the second pressing unit 74 .

[0078] Then, the first clamping plate 20 is lifted by the lifting unit 72, so that the first clamping plate 20 is separated from the lamination assembly A (such as Figure 1 and Figure 2 shown).

[0079] Then, the first clamping unit 73 releases the laminate assembly A, and the second clamping unit 74 releases the second clamping plate 30, and the bottom plate 10, the second clamping plate 30, 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 second clamping plate 30, 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.
