Technical Field
[0001] This application belongs to the field of lamination technology, and more specifically, relates to an upper lamination device and a lamination machine using the upper lamination device. Background Technology
[0002] A laminating machine is a device that stacks multiple electrode films into a product. The stacking process of multiple electrode films is usually carried out by an upper stacking device and a lower stacking device working together. Currently, the upper stacking device usually includes an upper stacking base and a cylinder for driving the upper stacking base to move up and down. The output end of the cylinder is connected to the upper stacking base to drive the upper stacking base to move closer to or away from the lower stacking base.
[0003] However, the lifting and lowering of the upper stacking seat is driven by a cylinder. When the upper stacking seat and the lower stacking seat work together to stack multiple electrode films, a large downward pressure is required. This places high demands on the output power of the cylinder, resulting in poor adaptability. Utility Model Content
[0004] The purpose of this application is to provide an upper stacking device and a stacking machine to solve the problem in the related art where the cylinder drives the upper stacking seat to rise and fall, resulting in insufficient stacking pressure between the upper stacking seat and the lower stacking seat, thus causing poor adaptability.
[0005] To achieve the above objectives, the technical solution adopted in the embodiments of this application is as follows:
[0006] On the one hand, an upper stacking device is provided, comprising:
[0007] Upper stacking support;

The two first sensors are spaced apart along the length direction of the stacking screw, and the first sensing plate is located between the two first sensors.
[0016] In one embodiment, the stacking screw, the stacking nut, the upper stacking seat, and the guide seat are combined to form an upper stacking unit. There are multiple upper stacking units, and the number of upper stacking drive units is the same as the number of upper stacking units. The multiple upper stacking drive units are respectively connected to multiple stacking screws.
[0017] In one embodiment, the upper stacking device further includes a stacking auxiliary seat and a stacking auxiliary power unit for driving the stacking auxiliary seat to rise and fall. The stacking auxiliary power unit is mounted on the upper stacking support, and the output end of the stacking auxiliary power unit is connected to the stacking auxiliary seat.
[0018] In one embodiment, the stacking auxiliary power unit includes a stacking auxiliary screw rotatably mounted on the upper stacking bracket, a stacking auxiliary nut mounted on the stacking auxiliary screw, and a stacking auxiliary motor for driving the stacking auxiliary screw to rotate forward and backward.

[0020] On the other hand, a stacking machine is provided, including the upper stacking device provided in any of the above embodiments.
[0021] The upper stacking device and laminating machine provided in this application have at least the following beneficial effects: This application rotatably mounts a stacking screw on an upper stacking bracket, and installs a stacking nut on the stacking screw, with the stacking nut connected to an upper stacking seat. When the upper stacking drive unit drives the stacking screw to rotate forward and backward, the stacking nut can reciprocate on the stacking screw, thereby driving the upper stacking seat closer to or away from the lower stacking seat. The cooperation between the upper and lower stacking seats achieves the stacking and forming of multiple electrode films.

[0038] Please see Figure 1 and Figure 2 The upper stacking device provided in this application embodiment will now be described. This upper stacking device includes an upper stacking bracket 1, a stacking screw 21, a stacking nut 22, an upper stacking seat 23, and an upper stacking drive unit 3. The upper stacking bracket 1 can be mounted on the frame of the stacking machine. The stacking screw 21 is rotatably mounted on the upper stacking bracket 1 and can rotate in both directions. The stacking nut 22 is mounted on the stacking screw 21 and can move up and down as the stacking screw 21 rotates. For example, when the stacking screw 21 rotates forward, the stacking nut 22 can move downward on the stacking screw 21; when the stacking screw 21 rotates in the reverse direction, the stacking nut 22 can move upward on the stacking screw 21. The upper stacking seat 23 is connected to the stacking nut 22 and can be driven by the stacking nut 22 to achieve lifting and lowering. Optionally, the upper stacking seat 23 can be sleeved on the stacking screw 21 and located at the bottom of the stacking screw 21. The upper stacking drive unit 3 is mounted on the upper stacking bracket 1, and the output end of the upper stacking drive unit 3 is connected to the stacking screw 21. The upper stacking drive unit 3 can drive the stacking screw 21 to rotate, thereby driving the upper stacking seat 23 to reciprocate on the stacking screw 21 through the stacking nut 22. By rotatably mounting the stacking screw 21 on the upper stacking bracket 1, and installing the stacking nut 22 on the stacking screw 21, the stacking nut 22 is connected to the upper stacking seat 23. When the upper stacking drive unit 3 drives the stacking screw 21 to rotate forward and backward, the stacking nut 22 can reciprocate on the stacking screw 21, thereby driving the upper stacking seat 23 to move closer to or away from the lower stacking seat. The stacking of multiple electrode films is achieved through the cooperation of the upper stacking seat 23 and the lower stacking seat. Through the driving cooperation of the upper stacking drive unit 3 and the stacking screw 21, the screw transmission efficiency is higher than that of the traditional cylinder transmission efficiency, and the precision is higher. It can effectively meet the stacking pressure requirements of multiple electrode films and has good adaptability.

In this structure, the stacking motor 31 drives the stacking driving wheel 32 to rotate, and the stacking belt 33 drives the stacking driven wheel 211 and the stacking screw 21 to rotate, thereby driving the upper stacking seat 23 to move closer to or away from the lower stacking seat.
[0040] In one embodiment, both the outer peripheral surfaces of the stacking drive wheel 32 and the stacking driven wheel 211 are provided with toothed grooves, and the inner side of the stacking belt 33 is provided with a rack that can mesh with the toothed grooves, thus preventing the stacking belt 33 from slipping. Of course, in other embodiments, the stacking motor 31 and the stacking lead screw 21 can also be connected by a gear set; or, the upper stacking drive unit 3 can also be a motor directly connected to the stacking lead screw 21, without making a limitation here.
[0041] In one embodiment, see Figure 2 As a specific embodiment of the upper stacking device provided in this application, the upper stacking device further includes a guide seat 24. One end of the guide seat 24 is connected to the stacking nut 22, and the other end of the guide seat 24 is slidably mounted on the upper stacking bracket 1. The guide seat 24 can be located between the stacking nut 22 and the upper stacking seat 23. This structure allows for the lifting and positioning of the upper stacking seat 23 and the stacking nut 22 via the guide seat 24, thereby improving the accuracy of each stacking operation of the upper stacking seat 23.
[0042] In one embodiment, see Figure 1 and Figure 2 As a specific embodiment of the upper stacking device provided in this application, a guide rail 11 is installed on the upper stacking bracket 1, and the guide rail 11 is arranged parallel to the stacking screw 21; a slider 241 is installed on the guide seat 24, and the slider 241 is slidably installed on the guide rail 11. This structure can improve the reliability of the reciprocating lifting and lowering of the guide seat 24 through the sliding cooperation between the slider 241 and the guide rail 11.

The two first sensors 12 are spaced apart along the length direction of the stacking screw 21, and the first sensing plate 242 is located between the two first sensors 12. With this structure, through the sensing cooperation between the first sensing plate 242 and the two first sensors 12, the lifting stroke of the guide seat 24 can be sensed and limited, thereby limiting the lifting stroke of the upper stacking seat 23.
[0044] In one embodiment, see Figure 1 and Figure 2 As a specific embodiment of the stacking device provided in this application, the stacking screw 21, stacking nut 22, upper stacking seat 23, and guide seat 24 are combined to form an upper stacking unit 2. There are multiple upper stacking units 2, and the number of upper stacking drive units 3 is the same as the number of upper stacking units 2. The multiple upper stacking drive units 3 are respectively connected to multiple stacking screws 21. This structure, through the cooperation of multiple upper stacking units 2 and multiple upper stacking drive units 3, enables multiple upper stacking seats 23 to perform stacking operations on the electrode films, improving the uniformity of the stacking force.
[0045] In one embodiment, see Figure 1 and Figure 3 As a specific embodiment of the upper stacking device provided in this application, the upper stacking device further includes a stacking auxiliary seat 4 and a stacking auxiliary power unit 5 for driving the stacking auxiliary seat 4 to rise and fall. The stacking auxiliary power unit 5 is mounted on the upper stacking support 1, and the output end of the stacking auxiliary power unit 5 is connected to the stacking auxiliary seat 4. In this structure, the stacking auxiliary seat 4 can be driven to rise and fall by the stacking auxiliary power unit 5, and the stacking auxiliary seat 4 can cooperate with the upper stacking seat 23 to realize the stacking process of the electrode film.
[0046] In one embodiment, see Figure 1 The number of upper stacking units 2 and upper stacking drive units 3 can both be four, with the four upper stacking units 2 arranged in a ring array around the stacking auxiliary power unit 5. In this structure, the four upper stacking units 2 can provide stacking pressure at the four corners of the electrode film, and the stacking auxiliary seat 4 can provide stacking pressure at the center of the electrode film.
[0047] In one embodiment, see Figure 3As a specific embodiment of the upper stacking device provided in this application, the stacking auxiliary power unit 5 includes a stacking auxiliary screw 51 rotatably mounted on the upper stacking bracket 1, a stacking auxiliary nut 52 mounted on the stacking auxiliary screw 51, and a stacking auxiliary motor 53 for driving the stacking auxiliary screw 51 to rotate forward and backward. The stacking auxiliary motor 53 is mounted on the upper stacking bracket 1, and the output shaft of the stacking auxiliary motor 53 is connected to the stacking auxiliary screw 51. The stacking auxiliary seat 4 is connected to the stacking auxiliary nut 52, and the stacking auxiliary screw 51 and the stacking screw 21 are arranged parallel to each other. In this structure, the stacking auxiliary screw 51 is driven to rotate forward and backward by the stacking auxiliary motor 53, and the stacking auxiliary nut 52 can be raised and lowered on the stacking auxiliary screw 51, which in turn can drive the stacking auxiliary seat 4 to be raised and lowered. This can cooperate with the upper stacking seat 23 to realize the stacking and forming of the electrode film.
[0048] In one embodiment, see Figure 3 As a specific embodiment of the upper stacking device provided in this application, a second sensing plate 41 is installed on the stacking auxiliary seat 4, and two second sensors 13 are installed on the upper stacking bracket 1. The two second sensors 13 are spaced apart along the length direction of the stacking auxiliary lead screw 51, and the second sensing plate 41 is located between the two second sensors 13. With this structure, the lifting stroke of the stacking auxiliary seat 4 can be limited by the sensing cooperation between the second sensing plate 41 and the two second sensors 13.

The laminating nut 22 is connected to an upper laminating seat 23. When the upper laminating drive unit 3 drives the laminating screw 21 to rotate forward and backward, the laminating nut 22 can reciprocate on the laminating screw 21, thereby driving the upper laminating seat 23 to move closer to or away from the lower laminating seat. The laminating of multiple electrode films is achieved through the cooperation between the upper laminating seat 23 and the lower laminating seat. Through the driving cooperation of the upper laminating drive unit 3 and the laminating screw 21, the screw transmission efficiency is higher than that of traditional cylinder transmission, and the precision is higher, effectively meeting the laminating pressure requirements of multiple electrode films and exhibiting good adaptability.
