[0002] In the battery manufacturing process, cell stacking is required, and the stacking table is mainly used to carry the electrode sheets and separators to be stacked into cells with mutual isolation. At present, there are different types of stacking tables on the market. Traditional stacking machines control the up-down and back-and-forth movement of the pressing knife by a cylinder. Cylinder control has problems such as low reliability, slow movement, short life and large size. Utility Model Content

[0003] To address the aforementioned problems in the existing technology, this utility model provides a novel stacking stage, the specific technical solution of which is as follows:

[0004] A novel stacking stage includes a base, a left pressure claw device, and a right pressure claw device. The left pressure claw device is installed on the left side of the base, and the right pressure claw device is installed on the right side of the base. The left pressure claw device and the right pressure claw device have the same structure. The right pressure claw device includes a motor eccentric transmission mechanism, a motor screw lifting mechanism, and a pressure claw assembly. The motor eccentric transmission mechanism drives the pressure claw assembly to move horizontally, and the motor screw lifting mechanism drives the pressure claw assembly to move up and down.

[0005] As a preferred embodiment of this utility model, the motor eccentric transmission mechanism includes a first motor, a driving pinion, a gear eccentric wheel, a linkage mechanism, and a linear slide rail. The driving pinion is mounted on the output shaft of the first motor. The first motor transmits power to the gear eccentric wheel through the driving pinion. The rotation of the gear eccentric wheel drives the linkage mechanism to swing. A pressure claw assembly is connected above the linkage mechanism. The pressure claw assembly is slidably connected to the linear slide rail, which is installed horizontally.

[0006] As a preferred embodiment of this utility model, the linkage mechanism includes a crank, a connecting plate, a slide block, and a swing plate. The crank is mounted on the eccentric shaft of the gear eccentric wheel. The connecting plate is connected above the crank. The slide block is slidably connected to the back of the connecting plate. The swing plates are connected to both sides of the connecting plate. The swing plates are connected to the pressure claw assembly.

[0007] As a preferred embodiment of this utility model, the motor screw lifting mechanism includes a second motor, a screw, a nut, and a lifting connecting block. The second motor drives the screw to rotate, the screw is threadedly connected to the nut, the nut is installed inside the lifting connecting block, and a pressure claw assembly is connected above the lifting connecting block.

[0008] As a preferred embodiment of this utility model, the pressure claw assembly includes a front sliding seat, a front cylinder, a front pressure claw, a rear sliding seat, a rear cylinder, and a rear pressure claw. The front cylinder is installed on the side of the front sliding seat and drives the front pressure claw to press down on the electrode sheet. The rear cylinder is installed on the side of the rear sliding seat and drives the rear pressure claw to press down on the electrode sheet.

[0009] As a preferred embodiment of this utility model, a pressure regulating valve for adjusting the pressure claws is installed around the base.

[0010] Beneficial effects: The stacking table can change the movement trajectory of the pressure claw by changing the motor motion curve of the motor screw lifting mechanism and the motor eccentric transmission mechanism, which can achieve arbitrary trajectory adjustment. Using a motor as the power source, a planned motor curve can be used to improve the movement speed and accuracy of the stacking table. Through this structural design, a smaller size structure can be achieved. Attached Figure Description

[0016] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the position or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

The right pressure claw device 3 includes a motor eccentric transmission mechanism 31, a motor screw lifting mechanism 32, and a pressure claw assembly 33. The motor eccentric transmission mechanism 31 drives the pressure claw assembly 33 to move horizontally, and the motor screw lifting mechanism 32 drives the pressure claw assembly 33 to move vertically.

[0019] like Figure 2 and 3 As shown, the eccentric transmission mechanism of the motor includes a first motor 311, a driving pinion 312, a gear eccentric wheel 313, a connecting rod mechanism, and a linear slide rail 315. The driving pinion 312 is mounted on the output shaft of the first motor. The first motor 311 transmits power to the gear eccentric wheel 313 through the driving pinion 312. The rotation of the gear eccentric wheel 313 drives the connecting rod mechanism to swing. The connecting rod mechanism includes a crank 316, a connecting plate 317, a slide block 318, and a swing plate 319. The crank 316 is mounted on the eccentric shaft of the gear eccentric wheel 313. 6.

Pressure claw assembly 33 is connected above the linkage mechanism. Pressure claw assembly 33 is slidably connected to linear slide rail 315. Linear slide rail 315 is horizontally installed. The rotation of gear eccentric wheel 313 causes crank 316 to move. Crank 316 drives swing plate 319 to swing through connecting plate 317. Since linear slide rail 315 is horizontally installed, pressure claw assembly 33 moves horizontally.

[0020] like Figure 4 As shown, the motor screw lifting mechanism 32 includes a second motor 321, a screw 322, a nut, and a lifting connecting block 324. The second motor 321 drives the screw 322 to rotate. The screw 322 is threadedly connected to the nut, which is installed inside the lifting connecting block 324. A pressure claw assembly 33 is connected above the lifting connecting block 324.

The front sliding seat 331 and the rear sliding seat 334 are slidably connected to a linear slide rail 315. The swing plates 319 on both sides are respectively connected to the front sliding seat 331 and the rear sliding seat 334. The linear slide rail 315 is installed on a horizontal plate 320. Vertical plates are installed at the bottom of both sides of the horizontal plate 320. The vertical plates are slidably connected to the base 1. The lifting connecting block 324 is connected to the middle of the horizontal plate 320. The front cylinder 332 is installed on the side of the front sliding seat 331. The front cylinder 332 drives the front pressure claw 333 to press down on the electrode. The rear cylinder 335 is installed on the side of the rear sliding seat 334. The rear cylinder 335 drives the rear pressure claw 336 to press down on the electrode. The pressure regulating valve 4 for adjusting the pressure claw is installed around the base 1.

It should not be considered that the specific implementation of the present utility model is limited to these descriptions.
