[0021] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] The embodiment of the present application provides a lamination assembly, which can solve the technical problem of low lamination efficiency in the related art of using a screw rod to separately control the lateral and longitudinal movement of the pressing knife.

[0023] See also Figure 1As shown, a lamination assembly provided by an embodiment of the present application may include: a support assembly 1; an integrated module, the integrated module including a first linear motor 21 and a lamination table 22 installed on the first linear motor 21, the first mover and the second mover of the first linear motor 21 are both installed with a second linear motor 23, and each of the second linear motors 23 is installed with a press assembly 24, the support assembly 1 can support the integrated module, and the press assembly 24 can press the pole piece placed on the lamination table 22; the first linear motor 21 is configured to drive the second linear motor 23 to move horizontally, and the second linear motor 23 is configured to drive the press assembly 24 to move longitudinally, the first linear motor 21 and the second linear motor 23 drive the structures installed on each automatic member to move horizontally and longitudinally respectively, so that the press assembly 24 can complete the pressing of the pole piece.

[0024] The embodiment of the present application fixes the knife pressing assembly 24 to the second linear motor 23, so that the first linear motor 21 can drive the knife pressing assembly 24 to move in the horizontal direction, and the second linear motor 23 drives the knife pressing assembly 24 to move in the longitudinal direction. Since the knife pressing assembly 24 is fixed to the second linear motor 23, when the first linear motor 21 drives the second linear motor 23 to move in the horizontal direction, the knife pressing assembly 24 is also synchronously driven to move in the horizontal direction. Furthermore, the second linear motors 23 respectively installed on the first mover and the second mover are arranged on opposite sides of the stacking table 22, which means that knife pressing assemblies 24 are arranged on opposite sides of the stacking table 22, and the first linear motor 21 The knife pressing assemblies 24 on both sides of the stacking platform 22 can be driven to move toward or away from each other, so that the knife pressing assemblies 24 on both sides of the stacking platform 22 can synchronously press the pole pieces placed on the stacking platform 22. At this time, the two second linear motors 23 can be connected to a controller, and the controller controls the movers on the second linear motors 23 to move simultaneously. The first linear motor 21 and the second linear motor 23 both directly convert electrical energy into mechanical energy of linear motion, thereby increasing the moving speed of the knife pressing assembly 24, thereby improving the overall working efficiency of the stacking platform 22, and solving the technical problem of low stacking efficiency in the related technology of using screw rods to separately control the horizontal and vertical movement of the knife pressing.

[0025] In some optional embodiments, the support assembly 1 may include: a support bottom plate 11 and limiting plates 12 fixed to opposite sides of the support bottom plate 11. The support bottom plate 11 is provided with a through-hole for a component. The support bottom plate 11 and the limiting plates 12 on both sides thereof can jointly form a "U" shape; an electric cylinder lifting assembly 13, the electric cylinder lifting assembly 13 is fixed to the support bottom plate 11, and the piston rod of the electric cylinder lifting assembly 13 passes through the through-hole and is connected to the first linear motor 21. The electric cylinder lifting assembly 13 drives the first linear motor 21 to move longitudinally. In the embodiments of the present application, driving the first linear motor 21 to move longitudinally by the electric cylinder lifting assembly 13 means that the lamination table 22 can be driven to move longitudinally. It should be understood that when laminating, a pole piece placement manipulator is usually used to place the pole piece on the lamination table 22. After one lamination is completed, a lamination picking manipulator is used to take away the lamination. The pole piece placement manipulator and the lamination picking manipulator can be arranged at different heights to cooperate with the lamination table 22. In the embodiments of the present application, by setting the electric cylinder lifting assembly 13, the lamination table 22 can move a certain distance longitudinally relatively quickly, enhancing the placement efficiency of the pole piece and the picking efficiency of the lamination.

[0026] In some optional embodiments, vertical slide rails are provided on both of the limiting plates 12, that is, vertical slide rails can be provided on the limiting plates 12 located on opposite sides of the support bottom plate 11. The first linear motor 21 is fixed with sliders that cooperate with the vertical slide rails. The limiting plates 12 can limit the first linear motor 21, reducing the possibility of the first linear motor 21 falling out of the support assembly 1. In the embodiments of the present application, the support bottom plate 11, the limiting plates 12, and the vertical slide rails can be an integrally formed structure. By fixing sliders that cooperate with the vertical slide rails on both sides of the first motor respectively, the first linear motor 21 can be further prevented from disengaging from the support assembly 1, and the first linear motor 21 can move more smoothly longitudinally.

[0027] In some optional embodiments, a reinforcing plate 211 is fixed to the side of the first linear motor 21 away from the second linear motor 23. The reinforcing plate 211 is slidably installed on the vertical slide rail. The reinforcing plate 211 can enhance the support stability of the support assembly 1 for the first linear motor . Slidingly installing the reinforcing plate 211 on the vertical slide rail can reduce its influence on the movement of the first linear motor 21 while enhancing the support stability of the first linear motor 21.

[0028] In some optional embodiments, the integrated module may further include: a screw lifting assembly, one end of the screw lifting assembly is supported on the stacking table 22, and the other end is connected to the first linear motor 21, and the screw lifting assembly is configured to drive the stacking table 22 to move longitudinally. It should be understood that during the process of pressing a stack several times, in order to enhance the accuracy of the pole piece pressing position, each pole piece is usually pressed at the same height. Therefore, in order to ensure that after the previous pole piece is placed on the stacking table 22 and the pressing is completed, and the next pole piece is placed on the pole piece, the pressing knife assembly 24 can still maintain the same height to press the next pole piece. Therefore, during the pressing process of a stacking, the stacking table 22 needs to be lowered to a certain height each time the pole piece is pressed. In the embodiment of the present application, the screw lifting assembly is used to drive the stacking table 22 to move longitudinally, so that each height adjustment of the stacking table 22 can be relatively subtle and have better adjustment accuracy, that is, the final stacking can have a higher pass rate.

[0029] In some optional embodiments, the screw lifting assembly includes a screw module fixing part 251 and a screw assembly 252 connected to the screw module fixing part 251, the screw module fixing part 251 is fixed to the stacking table 22, and the screw module fixing part 251 should be arranged on the side of the stacking table 22 close to the first linear motor 21; the first linear motor 21 is equipped with a vertical linear rail 212, and the vertical linear rail 212 is arranged on opposite sides of the screw lifting assembly, and the vertical linear rail 212 is spaced apart from the screw lifting assembly and the stacking table 22 respectively. It should be understood that in order to ensure that the two sets of knife pressing assemblies 24 are always located on the opposite sides of the stacking table 22 as much as possible, On the other hand, the first mover and the second mover can be set to a certain moving range. The first mover and the second mover usually do not move to the middle of the first linear motor 21. The vertical linear rail 212 can be fixed at the middle position of the first linear motor 21 near its longitudinal direction, and the first mover, the second mover and the vertical linear rail 212 will not interfere with each other; the opposite sides of the screw module fixing part 251 are fixed with moving blocks 2511 that cooperate with the vertical linear rail 212. With the cooperation of the moving block 2511 and the vertical linear rail 212, the occurrence of offset of the stacking table 22 can be reduced during the longitudinal movement, which has a certain guiding effect on the movement of the stacking table 22.

[0030] Preferably, a stabilizing slide 26 cooperating with the vertical linear rail 212 is fixed on one side of the stacking platform 22 close to the screw module fixing part 251. The stabilizing slide 26 and the moving block 2511 can be respectively arranged on opposite sides of the vertical rail. The stabilizing slide 26 can directly cooperate with the vertical linear rail 212, or a stabilizing block can be further arranged between the stabilizing slide 26 and the vertical linear rail 212. The stabilizing slide 26 slides relative to the vertical linear rail as the stacking platform 22 moves. The stabilizing slide 26 can further enhance the stability of the stacking platform 22 along the longitudinal movement, prevent it from deflecting during the movement, and enable the stacking work to proceed smoothly.

[0032] In some optional embodiments, the knife pressing assembly 24 may include: a control cylinder 241, the control cylinder 241 is fixed to the mounting seat 27, one side of the mounting seat 27 should be close to the lamination table 22, and the control cylinder 241 is arranged on the side of the mounting seat 27 away from the lamination table 22; a cutter head 242, the cutter head 242 is connected to the control cylinder 241, and the cutter heads 242 of at least two groups of the knife pressing assemblies 24 protrude toward the side close to each other, the cutter head 242 may have a vertical section and a transverse section, the transverse section extends toward the side close to the lamination table 22, and part of the transverse section is projected on the lamination table 22. During the lamination pressing process, the control cylinder 241 can always be in an open state, which can control the downward pressure of the cutter head 242 to prevent damage to the pole piece.

[0033] In some optional embodiments, the support assembly 1 is also fixed with a wire harness storage box 14, which can be installed on one side of the limit plate 12 in the support assembly 1.
