Description

Technical Field

[0001] The utility model relates to the field of battery winding machines, in particular to a lithium battery winding machine with a built-in disc loading mechanism. Background Art

[0002] The lithium battery winding machine in the prior art generally unloads the material after winding is completed, and the material is conveyed out of the machine by a belt, and the product is loaded onto a tray by an independent machine, that is, the tray loading machine is arranged outside the lithium battery winding machine as a separate discrete mechanism. Under this structure, the battery cell unloading is affected by the material roll and cannot be directly horizontally transferred to the right outside the machine body. An independent product lifting mechanism is required, which is composed of a set of clamps that can be opened and closed to clamp the battery cell, and form a height difference through eccentric rotation, or clamp the battery cell and lower it to avoid the electrode material roll. In addition, the battery cell passes under the material roll and is easily contaminated, so a dustproof plate needs to be made separately. The battery cell is loaded onto a tray outside the winding machine body, and then the defective product sorting mechanism and the battery cell loading mechanism are combined into an independent tray loading machine, which requires a large plant space, and the handling and loading and unloading of the whole machine is time-consuming and energy-consuming. Utility Model Content

[0003] The utility model provides a lithium battery winding machine with a built-in disc loading mechanism to solve at least one of the above technical problems.

[0004] To solve the above problems, as one aspect of the utility model, a lithium battery winding machine with a built-in disc loading mechanism is provided, comprising: a shell, a disc loading mechanism, a flattening device, a positive electrode material roll unloading mechanism, a negative electrode material roll unloading mechanism and a winding mechanism, the disc loading mechanism, the flattening device, the positive electrode material roll unloading mechanism, the negative electrode material roll unloading mechanism and the winding mechanism are all arranged in the shell, the disc loading mechanism and the winding mechanism are both arranged between the positive electrode material roll unloading mechanism and the negative electrode material roll unloading mechanism, the materials on the positive electrode material roll unloading mechanism and the negative electrode material roll unloading mechanism are both transported to the winding mechanism, and the products output by the winding mechanism are transmitted to the disc loading mechanism after passing through the flattening device.

[0005] Preferably, a second CCD detection mechanism, a diaphragm cutting mechanism, a tail glue sticking mechanism, and a material unloading mechanism are sequentially arranged between the winding mechanism and the flattening device.

[0006] Preferably, a Hipot testing mechanism, a belt transmission mechanism, a third CCD detection mechanism, and a defective product sorting mechanism are sequentially arranged between the flattening device and the tray loading mechanism.

[0007] Due to the adoption of the above technical solution, the utility model integrates the loading mechanism into the shell of the lithium battery winding machine, so that the product (i.e., the battery cell) can be loaded on the plate inside the winding machine body, without the need to design a special lifting mechanism for product transportation. At the same time, the product does not pass under the material roll, reducing dust pollution. In addition, the product is sorted as defective products after being flattened, reducing the transportation distance.

[0008] The utility model has the following characteristics: short conveying distance, reduced pollution; saving the cost of the outer cover of the tray loading machine, reducing the occupied space, no need to increase the product lifting, and simplifying the handling and installation.

[0011] The following is a detailed description of the embodiments of the present invention, but the present invention can be implemented in many different ways as defined and covered by the claims.

[0012] As one aspect of the utility model, a lithium battery winding machine with a built-in disc loading mechanism is provided, comprising: a shell 1, a disc loading mechanism 2, a flattening device 3, a positive electrode material roll unloading mechanism, a negative electrode material roll unloading mechanism and a winding mechanism 4, wherein the disc loading mechanism 2, the flattening device 3, the positive electrode material roll unloading mechanism, the negative electrode material roll unloading mechanism and the winding mechanism 4 are all arranged in the shell 1, the disc loading mechanism 2 and the winding mechanism 4 are both arranged between the positive electrode material roll unloading mechanism and the negative electrode material roll unloading mechanism, the materials on the positive electrode material roll unloading mechanism and the negative electrode material roll unloading mechanism are both transported to the winding mechanism 4, and the product output by the winding mechanism 4 is transmitted to the disc loading mechanism 2 after passing through the flattening device 3.

[0013] Preferably, a second CCD detection mechanism 22 , a diaphragm cutting mechanism 23 , a tail glue sticking mechanism 24 , and a material unloading mechanism 25 are sequentially arranged between the winding mechanism 4 and the flattening device 3 .

[0014] Preferably, a Hipot testing mechanism 26, a belt transmission mechanism 27, a third CCD detection mechanism 28, and a defective product sorting mechanism 29 are sequentially arranged between the flattening device 3 and the tray loading mechanism 2.

[0015] Among them, each of the above-mentioned mechanisms can adopt the corresponding mechanisms conventional in the field to achieve the corresponding functions, which will not be repeated here.

[0016] In order to explain the present invention more clearly, the structures of the positive electrode material roll unwinding mechanism, the negative electrode material roll unwinding mechanism and the diaphragm unwinding mechanism matched therewith in the present invention are described in detail below. These mechanisms in the present invention belong to the prior art and can be implemented by using the existing structures known in the art. The following are only preferred specific structural implementations.

[0017] Preferably, the positive electrode material roll unwinding mechanism and the negative electrode material roll unwinding mechanism have the same structure, and the positive electrode material roll unwinding mechanism includes a pole piece unwinding mechanism 5, an unwinding tension mechanism 6, a laser cutting mechanism 7, a dust removal mechanism 8, a cache mechanism 9, a gluing mechanism 10, a driving mechanism 11, a first CCD detection mechanism 13, a pole piece tension mechanism 12, a correction mechanism 14, a pole piece length measuring mechanism 15, and a cutting and feeding mechanism 16 which are arranged in sequence.

[0018] Preferably, a pre-rolling mechanism 17 is provided between the cutting and feeding mechanism 16 and the winding mechanism 4 .

[0019] Preferably, the lithium battery winding machine further comprises an upper diaphragm unloading mechanism cooperating with the positive electrode material unloading mechanism, and a lower diaphragm unloading mechanism cooperating with the negative electrode material unloading mechanism.

[0020] Preferably, the upper diaphragm unloading mechanism has the same structure as the lower diaphragm unloading mechanism, and the upper diaphragm unloading mechanism includes a diaphragm unwinding mechanism 18, a diaphragm tension mechanism 19, a static electricity removal mechanism 20 and a diaphragm length measuring mechanism 21 which are arranged in sequence.

[0021] In the above technical scheme, the utility model places the positive electrode material coil unwinding mechanism on the right side and the negative electrode material coil unwinding mechanism on the left side. The two, the disc loading mechanism 2, the flattening device 3, and the winding mechanism 4 are all well-known structures or technologies in the prior art, and any known structure in the prior art can be adopted. The working process and principle from the positive electrode material coil unwinding mechanism, the negative electrode material coil unwinding mechanism to the winding mechanism 4 are the same as those in the prior art, and will not be repeated here.

[0022] During operation, after the clamp of the unloading mechanism 25 clamps the battery cell 30, the battery cell 30 is transferred via another clamp. During this process, there is no height difference, so the lifting mechanism in the prior art can be eliminated, and the battery cell 30 is directly placed on the flattening mechanism 3. During this period, the product is flattened, Hipot tested, CCD tested, etc., and finally transported by the belt transmission mechanism 27 for defective product sorting and battery cell tray loading.

[0023] Due to the adoption of the above technical solution, the utility model integrates the loading mechanism 2 into the shell 1 of the lithium battery winding machine, so that the product (i.e., the battery cell 30) can be loaded into the winding machine body, without the need to design a special lifting mechanism for product transportation. At the same time, the product does not pass under the material roll, reducing dust pollution. In addition, the product is sorted for defective products after being flattened, reducing the transportation distance.

[0024] The utility model has the following characteristics: short conveying distance, reduced pollution; saving the cost of the outer cover of the tray loading machine, reducing the occupied space, no need to increase the product lifting, and simplifying the handling and installation.

[0025] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
