[0030] The following will clearly and completely describe the concept, specific structure and technical effects of the utility model in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technical personnel in this field without creative work are all within the scope of protection of the utility model. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the utility model can be combined interchangeably without conflicting with each other, refer to Figure 1-7 .

[0031] The utility model provides:

[0032] Reference Figure 1-3A diaphragm swing roller mechanism includes a swing roller reciprocating drive device and a swing roller mounting frame 12 arranged at the output end of the swing roller reciprocating drive device, a diaphragm swing roller assembly is arranged on the swing roller mounting frame 12, and the swing roller reciprocating drive device is used to drive the diaphragm swing roller assembly to reciprocate linear motion so that the diaphragm 9 passing through the diaphragm swing roller assembly swings back and forth.

[0033] In this embodiment, the swing roller reciprocating drive device includes a linear motor device 11, and the swing roller mounting frame 12 is mounted on the output end of the linear motor device 11. The linear motor device 11 can drive the diaphragm swing roller assembly to reciprocate linearly through the swing roller mounting frame 12. In other embodiments, if necessary, the implementer can also use other mechanisms that can perform linear reciprocating motion as the swing roller reciprocating drive device, such as a motor screw mechanism, an electric cylinder mechanism, etc.

[0034] In addition, in this embodiment, the diaphragm swing roller assembly includes a first swing roller group 13 and a second swing roller group 14, and the diaphragm 9 can pass through the first swing roller group 13 and pass out of the second swing roller group 14. Among them, the first swing roller group 13 includes two first swing rollers, and the second swing roller group 14 includes two second swing rollers. The two first swing rollers are arranged in pairs and there is a gap between the two first swing rollers for passing the diaphragm 9, and the two second swing rollers are arranged in pairs and there is a gap between the two second swing rollers for passing the diaphragm 9.

[0035] When used, the diaphragm first passes through the gap between the two first swing rollers of the first swing roller group 13, and then passes through the gap between the two second swing rollers of the second swing roller group 14. During the lamination process, the linear motor device 11 drives the first swing roller group 13 and the second swing roller group 14 to swing back and forth, and the amplitude and beat of the swing are consistent with the lamination requirements, which can be determined by machine preset settings and debugging.

[0036] In the present technical solution, after the diaphragm 9 passes through the second swing roller group 14, the linear motor device 11 drives the second swing roller group 14 to swing back and forth, and the reciprocating folding of the diaphragm can be achieved by relying on this function. Therefore, it is no longer necessary to set a special reciprocating device between the second swing roller group 14 and the stacking table to achieve the reciprocating folding of the diaphragm, so that the distance between the second swing roller group 14 and the stacking table can be set as small as possible, thereby improving the stacking efficiency.

[0037] Furthermore, a diaphragm pressing plate device is provided on the swing roller mounting frame 12, and the diaphragm pressing plate device includes a diaphragm pressing plate driving cylinder 15 and a diaphragm pressing plate 16 driven to rise and fall by the diaphragm pressing plate driving cylinder 15, and the diaphragm pressing plate driving cylinder 15 can drive the diaphragm pressing plate 16 to move downward to press the diaphragm at the corresponding stacking position. During the stacking process, when the diaphragm 9 is in the reciprocating folding process, the diaphragm pressing plate 16 is driven downward by the diaphragm pressing plate driving cylinder 15, and the lower end of the diaphragm pressing plate 16 will press the diaphragm to avoid the change of the diaphragm position during the folding process, thereby ensuring the stacking quality. The diaphragm pressing plate 16 has two pieces, and the two diaphragm pressing plates 16 press the diaphragms at both ends in turn.

[0038] In this embodiment, the diaphragm plate driving cylinder 15 converts the linear motion of its output shaft into the lifting motion of the diaphragm plate 16 through a transmission mechanism, and the transmission mechanism can use an existing device that meets the requirements to perform its motion conversion function. In other embodiments, if it meets the needs, an electric cylinder, an oil cylinder, or a motor screw mechanism can be used to replace the diaphragm plate driving cylinder 15.

[0039] Furthermore, the membrane swing roller mechanism also includes a membrane roller device fixedly connected to the swing roller reciprocating drive device. In this embodiment, the membrane roller device includes a fixed roller 17, a correction roller 18 and a correction roller drive device for driving the correction roller 18.

[0040] In use, after the diaphragm 9 is unwound from the diaphragm unwinding mechanism, the diaphragm 9 first passes around the fixed roller 17, and then passes around the deflection correction roller 18. In the process of the diaphragm passing around the deflection correction roller 18, the deflection correction roller driving device drives the deflection correction roller 18 to perform corresponding actions to correct the deflection of the diaphragm 9, and the diaphragm 9 after the deflection correction process enters the first swing roller group 13 and the second swing roller group 14.

[0041] Among them, the deviation correction roller driving device can use existing air cylinders, oil cylinders, electric cylinders, motor screw mechanisms and other devices as actuators, which will not be repeated here.

[0042] Based on the above-mentioned diaphragm swing roller mechanism, the utility model also provides:

[0043] Reference Figure 4-7 , a lamination device, the lamination device includes the diaphragm swing roller mechanism, and also includes a lamination table module 2, a pole piece clamping module 4 and a knife pressing module 3 arranged on the front and rear sides of the lamination table module 2. The lamination table module 2 is used for lamination of pole pieces and diaphragms 9, the pole piece clamping module 4 is used to sequentially send pole pieces from both sides to corresponding lamination positions on the lamination table module 2, and the knife pressing module 3 is used to press the pole pieces placed on the lamination table module 2 to prevent displacement of the pole piece position.

[0044] Specifically in the present embodiment, the stacking table module 2 includes a stacking table linear motor device 21 and a lifting stacking table 22 arranged on the output end of the stacking table linear motor device 21. The stacking table linear motor device 21 can drive the entire lifting stacking table 22 to perform a linear position. The pressing knife module 3 is also arranged on the output end of the stacking table linear motor device 21 and can move horizontally synchronously with the lifting stacking table 22.

[0045] The lifting stacking platform controls the lifting drive device, the lifting guide and the stacking platform. The stacking platform is lifted and guided by the lifting guide. The action end of the lifting drive device is connected to the lifting platform and can drive the lifting platform to perform lifting movements. The lifting drive device can use a motor screw device as an actuator to achieve precise lifting stroke control. During the stacking process, the diaphragm 9 and the pole piece are stacked at the stacking platform. For each pole piece stacked on the stacking platform, the lifting drive device can drive the stacking platform to drop by the corresponding stacked thickness, so that the stacking plane on the stacking platform is always consistent, thereby improving the stacking consistency and improving product quality.

[0046] In addition, the press tool module 3 includes a press tool drive device 31 and a pole piece press tool 32 arranged at the output end of the press tool drive device 31, and a pole piece tab press sheet 33 is arranged on the pole piece press tool 32. In the present embodiment, the press tool drive device 31 adopts a motor screw mechanism as an actuator. In other embodiments, other driving devices can also be used as actuators if they meet the requirements. When used, the press tool drive device 31 can drive the pole piece press tool 32 to press the pole piece to avoid changes in the position of the pole piece. Synchronously, the pole tab press sheet 33 also presses the pole piece of the pole piece, thereby effectively improving the quality of the product lamination.

[0047] Furthermore, the pole piece clamping module 4 has two groups and is symmetrically arranged on the left and right sides of the stacking table module 2. The pole piece clamping module 4 is used to clamp the pole piece and place the pole piece on the stacking table module 2. When used, the pole piece clamping module 4 can adopt an existing manipulator device that can be used to carry pole pieces, including a clamping type clamp, an adsorption type clamp, etc.
