Description

Technical Field

[0001] This utility model belongs to the field of current collector production, and in particular relates to a positioning tooling for battery current collector production. Background Technology

[0002] In a battery, the current collector mainly functions to collect and conduct current. It is usually in full contact with the active material of the electrode so as to collect the current generated by the active material to form a larger current output. At the same time, the current collector can also separate the positive and negative electrodes of the battery, preventing electrochemical reactions from occurring directly inside the battery, thereby avoiding problems such as short circuits. Alkaline environmentally friendly batteries are batteries with high capacity, stable voltage, good environmental performance and long storage life, and are widely used in many fields. The current collector of alkaline environmentally friendly batteries is made of brass wire that has been stretched and straightened into a needle shape. Positioning fixtures are required during its production.

[0003] Comparing with Chinese Patent No. CN218743987U, a positioning fixture is disclosed, including a positioning base, a mold positioning block, and a wire drawing mold. The mold positioning block is welded to the upper end of the positioning base, and a positioning groove is formed on the mold positioning block. An alignment groove is formed at the bottom of the positioning groove. An alignment block is welded and fixed to the lower end of the wire drawing mold, and a positioning hole is formed at the upper end of the wire drawing mold. A positioning component is provided at the upper end of the mold positioning block. The positioning component includes a positioning motor. A telescopic rod assembly is connected to the lower end of the positioning motor, and a positioning pressure block is rotatably connected to the lower end of the telescopic rod assembly. Both the positioning pressure block and the positioning hole are circular structures.

[0004] The aforementioned patent can only position and clamp the stretching die, but it cannot position and guide the copper wire feed. Therefore, a new device needs to be designed. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 A positioning fixture for battery current collector production includes a main body device for positioning and fixing a mold, and a clamping device on the main body device for synchronously sliding and clamping copper wires. The clamping device is equipped with a guide device for clamping, guiding, and rolling straightening the copper wires.

[0025] In this embodiment: the main device includes a positioning base 101, a positioning plate 102 is provided at the rear end of the positioning base 101, a stretching die 103 is installed in the positioning plate 102, a fixing component is provided on the stretching die 103, the fixing component includes a screw 105, an insert block 106 is installed at the lower end of the screw 105, and a knob 104 is provided at the upper end of the screw 105. The positioning base 101 is fixed on the stretching equipment. In use, the screw 105 is rotated by the knob 104, which pushes the insert block 106 downward to insert into the top of the stretching die 103 and fix it inside the positioning plate 102.

[0026] In this embodiment: the clamping device includes a sliding assembly, a positive and negative threaded screw 202 is rotatably mounted in the middle of the sliding assembly, a motor 203 is mounted at the top of the positive and negative threaded screw 202, two sliding plates 205 are symmetrically slidably mounted on one side of the sliding assembly, the sliding assembly includes a slide base 201, two slide rods 204 are symmetrically arranged on both sides inside the slide base 201, the slide base 201 supports the motor 203 to drive the positive and negative threaded screw 202 to rotate, so that it pushes the two sliding plates 205 to slide relative to each other along the slide rods 204;

[0027] In this embodiment: the guiding device includes an upper mounting plate 301 and a lower mounting plate 303 symmetrically arranged vertically. An upper straight roller 302 is rotatably mounted on one side of the upper mounting plate 301, and a lower straight roller 304 is rotatably mounted on one side of the lower mounting plate 303. A front guide roller 305 is mounted at the front end of both the upper mounting plate 301 and the lower mounting plate 303, and a rear guide roller 306 is mounted at the rear end of both the upper mounting plate 301 and the lower mounting plate 303. There are three upper straight rollers 302 and two lower straight rollers 304, and the three upper straight rollers 302 and the two lower straight rollers 304 are arranged alternately. The front guide roller 305 and the rear guide roller 306 are both provided with limiting grooves 307. The limiting grooves 307 are arc-shaped. The slide plate 205 drives the upper mounting plate 301 and the lower mounting plate 303 to slide relative to each other, thereby driving the pair of front guide rollers 305 and rear guide rollers 306 to center and clamp the copper wire, so that the copper wire is located inside the limiting groove 307 and is limited and guided. At the same time, the upper straightening roller 302 and the lower straightening roller 304 approach each other to straighten the copper wire. After being straightened, the copper wire passes backward through the stretching die 103 under the limiting guidance of the rear guide roller 306 for stretching.

[0028] Working principle: The positioning fixture is fixed to the stretching equipment via the positioning base 101. In use, the screw 105 is rotated by the knob 104, causing it to push the insert block 106 downwards into the top of the stretching die 103 and fix it inside the positioning plate 102. Then, one end of the traction copper wire is introduced backwards between the two front guide rollers 305, passing between the upper straight roller 302 and the lower straight roller 304, and then exiting between the two rear guide rollers 306. Finally, the slide 201 supports the motor 203 to drive the positive and negative threaded screw 202 to rotate. This causes the two sliding plates 205 to slide relative to each other along the sliding rod 204. The sliding plates 205 then drive the upper mounting plate 301 and the lower mounting plate 303 to slide relative to each other, thereby driving the pair of front guide rollers 305 and rear guide rollers 306 to center and clamp the copper wire, so that the copper wire is located inside the limiting groove 307 and is limited and guided. At the same time, the upper straightening roller 302 and the lower straightening roller 304 move closer to each other to straighten the passing copper wire. After being straightened, the copper wire passes backward through the stretching die 103 under the limiting guidance of the rear guide roller 306 for stretching.
