Description

TECHNICAL FIELD

[0001] The utility model belongs to battery formation fixture technical field especially relates to a bidirectional clamping battery formation fixture. BACKGROUND

[0002] The battery formation fixture is used for battery formation. When the battery is formed, the battery is connected with the formation power supply, and the battery is pressurized when the battery is formed, so that pressure formation is realized. For example, the pressure formation device of the soft package battery adjustable spring module disclosed in the Chinese utility model patent with the authorization announcement number CN217405493U comprises a gear box and a front end plate, a driving motor and a speed reducer box arranged on the gear box and the front end plate, a rear end plate, a plurality of support shafts and a plurality of lead screws for connecting the gear box and the front end plate and the rear end plate, and a plurality of layer plates arranged equidistantly between the gear box and the front end plate and the rear end plate. The device further comprises a spring module arranged between the gear box and the front end plate and the rear end plate. The spring module comprises a reference plate mounted on the lead screw, a driving plate connected with the reference plate through a special-shaped bolt and a bolt, and a plurality of special-shaped bolts arranged in an array in the middle part of the reference plate and the driving plate. The lower part of the special-shaped bolt is provided with a spring, so as to adjust the compression amount of the spring arranged on the special-shaped bolt by rotating the special-shaped bolt.

[0003] In the technical scheme disclosed in the above patent document, the spring module is used to push the battery in one direction. If the formation fixture needs to form more batteries, the length of the fixture will be increased, so that the stroke will be increased when the battery is pushed, and the time for clamping the battery will be increased.

[0004] For example, the Chinese utility model patent with publication No. CN218004990U discloses a two-way compression structure's formation clamp, which comprises two mounting seats, two groups of lead screws, a power mechanism, two groups of compression mechanisms, a guide mechanism and laminated plates. The two mounting seats are oppositely arranged. The guide mechanism is arranged between the two mounting seats and is slidably connected to the guide mechanism. The two groups of lead screw assemblies are parallel to each other and are oppositely arranged on both sides of the laminated plates. Each lead screw assembly comprises at least one lead screw, and the two ends of the lead screw are provided with left-handed threads and right-handed threads, respectively. The left-handed threads are sleeved with a first nut sleeve, and the right-handed threads are sleeved with a second nut sleeve. One compression mechanism is connected to the first nut of the two groups of lead screw assemblies, and the other compression mechanism is connected to the second nut of the two groups of lead screw assemblies, and the laminated plates are located between the two compression mechanisms. The power mechanism is connected to the lead screw and is used for driving the lead screw to rotate, so that the two compression mechanisms move towards each other to press the laminated plates, or move in the opposite direction to release the laminated plates. When the battery is compressed between the laminated plates, the power mechanism drives each lead screw to rotate at the same time, and under the action of the left-handed threads and the right-handed threads of the lead screw, the two compression mechanisms can move towards each other at the same time, so as to push the laminated plates to translate along the guide mechanism, and the battery is compressed. After the formation is completed, the power mechanism drives each lead screw to rotate in the opposite direction, so that the two compression mechanisms move in the opposite direction, and the battery is completely released. Since the two compression mechanisms move towards each other or in the opposite direction at the same time when the battery is clamped and released, the time for the power mechanism to drive the lead screw to rotate and make the two compression mechanisms compress or completely release the laminated plates can be shortened, the efficiency is improved, and the efficiency of the formation is improved. It can be seen that the patent document can solve the problem of long movement time of the battery clamping spring module.

[0005] In the above patent document, the two groups of compression mechanisms are used to realize the clamping of the laminated plates by synchronous movement. However, the compression mechanisms in the patent document also use multiple independent compression springs to realize the pressure retention of the battery by compression. Since the two compression mechanisms move towards each other to compress the battery, there is no fixed supporting surface when the battery is compressed, and under the condition that the force of the spring is uneven, the problem of inclination of the pressing plate connected to the spring is easily caused. In addition, the thickness of the battery is different, and when the battery is compressed, the single spring is subjected to excessive force, which causes the problem of inclination of the pressing plate connected to the spring, resulting in uneven compression of the battery during the formation process and the inability to accurately control the pressure of the battery during the formation process.

[0038] Refer to Figure 4 and Figure 5The pushing mechanism 500 comprises a moving carrier plate 510, an elastic rubber plate 520 and a pressing plate 530. The moving carrier plate 510 is provided with a mounting hole, and a left-hand threaded nut 501 is arranged in the mounting hole. The elastic rubber plate 520 is provided with two side surfaces parallel to each other in the thickness direction, and the elastic rubber plate 520 and the pressing plate 530 are arranged in sequence on the inner side of the moving carrier plate 510.

Moreover, the second adjusting gear 350 is also convenient to assemble with the adjusting rod 910, and the second adjusting gear 350 does not need to be sleeved from one end of the adjusting rod 910. In addition, by connecting the second adjusting gear 350 with the gear shaft 912, the second gear 350 and the gear shaft 912 can be integrally machined; and after the diameter of the adjusting rod 910 is determined, the diameter of the second adjusting gear 350 can be effectively reduced, and then the size of the adjusting seat 320 is reduced, so that the adjusting seat 320 can avoid occupying a large space.
