Description

Technical Field

[0001] This utility model relates to the field of electrode production equipment technology, and in particular to an electrode winding device. Background Technology

[0002] In the lithium battery industry, electrode manufacturing involves coating positive and negative electrode slurries onto the surface of continuously running foil, drying them, and then winding them into electrode rolls for subsequent processing.

[0003] According to the search, the announcement number is CN109279423B, which describes an electrode unwinding and rewinding device. This device can prevent the electrode from shifting between the electrode and the winding roller during the winding process and ensure parallel unwinding and rewinding.

[0004] Existing technologies have the following problems:

[0005] In existing winding devices, after winding is completed, the electrode plates on the tensioning mechanism will disconnect from the electrode plates on the winding roller. As a result, the electrode plates on the winding roller will become loose due to the disconnection of the electrode plates, which is not conducive to subsequent use.

[0006] To address these shortcomings, we proposed an electrode winding device. Utility Model Content

A first transmission wheel is provided on the surface of the other winding roller. The first transmission wheel is connected to a second transmission wheel via a synchronous belt. The second transmission wheel is mounted on the surface of a tension roller. A first electric cylinder is provided on the side surface of the device body. A fixed roller is provided on the telescopic end of the first electric cylinder via a mounting base. The fixed roller is sleeved with the winding roller. A rotating ring is sleeved on the surface of the fixed roller. A telescopic rod is provided on the outer side of the rotating ring. A telescopic spring is provided inside the telescopic rod. A clamping wheel is provided on the side surface of the telescopic rod.

[0010] Preferably, a meter counter is provided at the end of one of the tensioning rollers.

[0014] Preferably, a control panel is provided on the side surface of the device body.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) In this utility model, the electrode roller is placed between the fixed rollers, the rotating ring is sleeved on the surface of the fixed roller, and the first electric cylinder is started at the same time to make the fixed roller and the electrode roller fixedly connected. Then the servo motor can be started to drive the winding roller. Under the action of the winding roller and the fixed roller, the electrode roller is driven to perform the winding operation. As the winding operation proceeds, the clamping wheel on the telescopic rod clamps the outer side of the electrode. Under the action of the telescopic spring, the electrode is fixed, which can prevent the electrode from becoming loose after winding.

[0017] (2) In this utility model, the meter counter is installed at the end of the tension roller. With the cooperation of the first transmission wheel, the second transmission wheel and the synchronous belt, the tension roller rotates synchronously with the winding roller, thereby driving the meter counter to perform meter counting operations, so that the winding length of the electrode sheet can be known in real time.

A telescopic spring 11 is provided inside the telescopic rod 10. A clamping wheel 12 is provided on the side surface of the telescopic rod 10.

[0027] In this implementation scheme: the electrode roller is placed between the fixed rollers 18, the rotating ring 9 is sleeved on the surface of the fixed roller 18, and the first electric cylinder 15 is started at the same time to make the fixed roller 18 and the electrode roller fixedly connected. Then the servo motor 2 is started to drive the take-up roller 3. Under the action of the take-up roller 3 and the fixed roller 18, the electrode roller is driven to perform the take-up operation. As the take-up operation is carried out, the clamping wheel 12 on the telescopic rod 10 clamps the outer side of the electrode and fixes the electrode under the action of the telescopic spring 11, which can prevent the electrode roll from loosening after winding.

[0028] Specifically, a meter counter 8 is provided at the end of a tension roller 4.

[0029] In this implementation scheme: the meter counter 8 will perform meter counting as the tension roller 4 rotates, thereby detecting the winding length of the electrode sheet in real time.

[0030] Specifically, a second electric cylinder 17 is provided on the inner bottom surface of the device body 1, and a support seat 16 is provided on the telescopic end of the second electric cylinder 17.

[0031] In this implementation scheme: the second electric cylinder 17 is used to push the support seat 16 so that the support seat 16 can support the electrode sheet, making it convenient to remove the electrode sheet from the winding device.

[0032] Specifically, the meter counter 8 is a roller-type meter counter 8, and the smallest unit of the meter counter 8 is 1cm.

[0033] In this implementation plan, the low price will greatly reduce the production cost of the winding device.

[0034] Specifically, the lower surface of the device body 1 is provided with support legs 13.

[0035] In this implementation plan: by setting support legs 13, the height of the device body 1 is increased, thereby reducing the erosion of the device body 1 by ground moisture.

[0036] Specifically, a control panel 14 is provided on the side surface of the device body 1.

[0037] In this implementation scheme: a control panel 14 is set up to control the winding device. The control circuit of the control panel 14 can be implemented by simple programming by those skilled in the art. It is common knowledge in the art. It is only used and not modified. Therefore, the control method and circuit connection will not be described in detail.

[0038] Working principle: The electrode roller is placed between the fixed rollers 18, and the rotating ring 9 is sleeved on the surface of the fixed roller 18. At the same time, the first electric cylinder 15 is started to fix the fixed roller 18 and the electrode roller. Then, the servo motor 2 is started to drive the take-up roller 3. Under the action of the take-up roller 3 and the fixed roller 18, the electrode roller is driven to perform the take-up operation. As the take-up operation is carried out, the clamping wheel 12 on the telescopic rod 10 clamps the outer side of the electrode. Under the action of the telescopic spring 11, the electrode is fixed and can prevent the electrode roll from loosening after winding.
