Embodiment 1

[0063] see Figure 1-Figure 9 , the present invention provides the following technical solutions:

[0064] A sheet feeding structure for a lithium battery winding machine, comprising:

[0065] The frame body 1, the frame body 1 is composed of a first support table 101, a second support table 102 and a side plate 103, such as figure 1 In the state shown, the second supporting platform 102 is located on one side of the first supporting platform 101, and the side plate 103 is fixed on the top of the second supporting platform 102;

[0066] see figure 1 , a telescopic mechanism 4 is provided on the top of the above-mentioned first supporting platform 101. In this embodiment, the telescopic mechanism 4 is a cylinder structure, but the telescopic mechanism 4 includes but is not limited to the above-mentioned embodiments. Screw nut structure, rack and pinion structure or other embodiments with linear motion, so they will not be described in detail;

[0067] see figure 1 and fi...

Embodiment 2

[0092] see Figure 1-Figure 9 , Since the pole piece is prone to deviation during the conveying process, this embodiment additionally sets up a deviation correction detection mechanism 10 and a deviation correction reading mechanism 11 on the basis of the embodiment 1, and the details are as follows:

[0093]The deviation correction detection mechanism 10 is arranged on the conveying table 3 and is located at the feeding position of the roller shaft feeding mechanism 9. It is also electrically connected with the upper control system to output the deviation correction signal. The deviation correction detection mechanism 10 is composed of the first screw nut assembly and the deviation correction detection mechanism. The first screw nut assembly is composed of a forward and reverse rotation motor 1001, a first screw rod 1002, a first nut 1003, an L-shaped plate 1004 and an adjustment block 1005. The L-shaped plate 1004 is fixed on the inner wall of the conveying table 3, The forw...

Embodiment 3

[0097] A working method for a sheet feeding structure of a lithium battery winding machine, comprising the following steps:

[0098] S1, the upper control system automatically brakes the moving mechanism 5 to shorten to realize the contact between the cutter orbit mechanism 6 and the signal transmission roller 7, when the cutter orbit mechanism 6 contacts the signal transmission roller 7, the upper control system stops the moving mechanism 5;

[0099] specific: as Figure 7 The pole piece walking path is set in the state shown, and the servo motor is driven to realize pole piece transportation. The upper control system automatically brakes the moving cylinder 502 to shorten, and the moving cylinder 502 shortens to drive the connecting bar 503 to move in a straight line, and then it moves through the guide rod 504 and moves. The seat 505 realizes that the track body 601 gradually approaches the signal transmission roller 7. When the innermost inner wall of the track body 601 is...

Abstract

The invention provides a sheet feeding structure of a lithium battery winding machine and a working method of the sheet feeding structure, and belongs to the technical field of lithium battery winding machines. The conveying table is arranged on the frame body; the roll shaft piece conveying mechanism is arranged on the conveying table and is used for conveying the pole pieces; the telescopic mechanism is arranged on the frame body; the sliding mechanism is arranged on the frame body in a sliding mode and connected with the telescopic mechanism, and sliding is achieved based on stretching and retracting of the telescopic mechanism; the moving mechanism is arranged on the sliding mechanism; the signal transmission roller is arranged on the conveying table; and the cutter track mechanism is arranged on the moving mechanism, the signal transmission roller makes contact with the cutter track mechanism based on stretching and retracting of the moving mechanism, and then the telescopic mechanism drives the sliding mechanism to slide so that the signal transmission roller can roll in the cutter track mechanism. The pole piece cutting device aims at solving the technical problem that in the prior art, due to the fact that a cutter is poor in structural stability, pole piece cutting cannot be rapidly and accurately achieved.

Description

technical field [0001] The invention belongs to the technical field of lithium battery winding machines, and in particular relates to a sheet feeding structure of a lithium battery winding machine and a working method thereof. Background technique [0002] As a green energy source, lithium-ion batteries have been widely used as power sources for mobile devices such as wireless communications, digital cameras, and notebook computers. The power source has a very broad application prospect. In the current lithium battery equipment, the winding form of the battery is adopted by the majority of lithium battery manufacturing enterprises due to its stable battery performance and high manufacturing efficiency, and the market accounts for a large proportion. Therefore, the corresponding battery winding machine demand is also large. [0003] The existing sheet feeding structure of the lithium battery winding machine generally includes a manipulator clamping structure, a manipulator s...
