Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery production, and particularly relates to a special scale for product switching of a winding machine. Background Technique

[0002] When the current battery production wire is pulled and products of different sizes need to be switched, tooling needs to be replaced. After replacement, the equipment needs to be re-adjusted; winding is a key process for the formation of battery cores. Every time the product is switched, the product material line and the position of the inductor need to be re-adjusted; when adjusting the material line, the normal electrode plate is used to run the equipment to debug the material line, and there is no special means for rapid debugging; every time products of different specifications are switched, tooling such as winding needles is replaced. After replacement, due to changes in the diameter of the winding needle, the thickness and width of the electrode plate, and the distance between the tabs, the winding machine cannot produce normal battery cores without debugging, and defects such as tab errors, inconsistent battery core widths, and inconsistent lengths cannot be processed into finished battery cores (when producing automotive batteries, there are requirements for the tabs, thickness, width, and length dimensions of the battery cores, and they need to be within the specified range); moreover, a large amount of electrode plates and time will be consumed when debugging the material line. Content of the Utility Model

[0003] The purpose of the utility model is to solve the problem that a large amount of electrode plates and time are consumed when debugging the material line during the product switching of the existing winding machine.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A special scale for product switching of a winding machine, characterized in that: it includes a magnetic adsorption base vertically adsorbed on the equipment large plate of the winding machine by magnetic adsorption, a vertical rod is detachably connected to the magnetic adsorption base, a first scale is arranged on the front surface of the vertical rod, and it also includes a first card and a second card that are slidably arranged up and down on the vertical rod for measuring the relative position of the edge of the electrode plate. A first sliding block and a second sliding block are slidably sleeved on the vertical rod, the second sliding block is located above the first sliding block, the first card is slidably inserted into the rear end of the first sliding block and is perpendicular to the vertical rod, the second card is slidably inserted into the rear end of the second sliding block and is perpendicular to the vertical rod, and it also includes a second scale vertically arranged on the second card for measuring the position of the tab.

[0006] A further improvement is that: both the first scale and the second scale have corresponding scales.

[0007] A further improvement is that: through holes for sliding are vertically penetrated in the middle of the first sliding block and the second sliding block, and the first sliding block and the second sliding block are slidably sleeved on the vertical rod through the corresponding through holes for sliding.

[0008] Further improvements are as follows: Card slots are horizontally and penetratingly opened at the rear ends of the first sliding block and the second sliding block. The first card is slidably inserted into the card slot of the first sliding block, and the second card is slidably inserted into the card slot of the second sliding block.

[0009] Further improvements are as follows: Both the first card and the second card are stainless steel cards.

[0010] Further improvements are as follows: A connecting seat is fixedly connected to the bottom of the vertical rod, and the connecting seat is detachably installed on the magnetic suction base.

[0011] Further improvements are as follows: Connecting seat threaded holes are symmetrically and vertically penetratingly opened on the connecting seats on both sides of the vertical rod, and base threaded holes corresponding to the connecting seat threaded holes are opened on the upper surface of the magnetic suction base.

The scale part determines the positions of the various sensors of the winding machine, as well as the positions of the sensor sensing the pole piece and the tab position; it can quickly achieve the debugging of the winding wire and reduce material consumption in the absence of materials;

[0016] It can conveniently and quickly measure data such as the relative edge distance of the pole piece and the position of the tab, facilitating the position adjustment of each sensor, shortening the product switching time, reducing the consumption of materials such as pole pieces, reducing the debugging difficulty, enabling the production wire to be quickly put into production, greatly improving the production efficiency, reducing human and material resources, and saving costs.

[0031] Among them, a magnetic absorption switch 11 is arranged on the magnetic absorption base 1.

[0032] Among them, the relative positions where each sensor should be located can be calculated through the following scheme according to the designed pole piece parameters (A: distance from the large plate to the side of the anode pole tab; B: pole piece width; C: pole tab height; D: pole tab width; E: distance between the edge of the pole piece and AT11; G: travel of the serpentine deviation correction sensor; L: depth of the Mark hole; F: four-stage deviation correction travel; E: length of the four-stage deviation correction pinch roll):

[0033] Product after cutting and pulling: position of AT11 (A + B - D);
