Description

Technical Field

[0001] This utility model relates to the field of battery production technology, specifically to a battery electrode group loading tool. Background Technology

[0002] A battery electrode group is a structure composed of several overlapping positive and negative plates; the electrode group has the functions of storing electrical energy, releasing electrical energy, and maintaining voltage stability. During battery production, the assembled electrode group needs to be pressed into the battery casing. Patent publication CN213936329U, "A Battery Electrode Group Insertion Device," provides a device that uses a second cylinder to drive a pressure plate downwards, pressing the battery electrode group into the battery casing.

[0003] However, since the width of the pressure plate does not change in the existing technology, and there are many specifications and models of electrode groups, when different specifications of electrode groups are put into the groove, in order to make the electrode groups bear force evenly, it is necessary to select a pressure plate of different widths according to the model of the electrode group, which has low flexibility and narrow application range. Summary of the Invention

[0004] This utility model addresses the problem that the tooling used for pressing electrode groups into the slot is difficult to adapt to electrode groups of different specifications. It provides a battery electrode group slotting tooling that can adjust the width of the slotting tooling according to different electrode group specifications, and has a wide range of applications.

[0005] To solve the above problems, the technical solution of this utility model is:

[0006] A battery terminal group insertion fixture includes a support plate, a pressure plate, and side pressure rods. There are two pressure plates, each U-shaped. The two pressure plates are slidably secured to the left and right sides of the support plate. A slotted hole is provided in the center of the support plate. A drive rod is rotatably connected between the left and right sides of the slotted hole. A drive ring is fixedly fitted around the center of the drive rod. External threads one and two are respectively provided on the peripheral walls of the drive rods on the left and right sides of the drive ring, with opposite thread directions. Connecting plates are threaded to the drive rods on both sides of the drive ring. Each connecting plate slides left and right within the slotted hole, and its upper and lower ends are connected to the upper and lower inner surfaces of the pressure plate on the same side. Side pressure rods are provided on opposite sides of the two pressure plates, and each side pressure rod is driven by a screw to move closer to or away from the pressure plate on the same side.

[0007] Furthermore, the upper and lower inner surfaces of each pressure plate slide in contact with the upper and lower surfaces of the bearing plate, respectively; and connecting rods are connected to the front and rear of the top surface of the bearing plate between the two pressure plates.

[0008] Furthermore, the two connecting plates are symmetrical about the middle of the drive rod. The left connecting plate is provided with a threaded hole 1 that corresponds to the external thread 1, and the right connecting plate is provided with a threaded hole 2 that corresponds to the external thread 2.

[0009] Furthermore, the lower end of the drive ring is higher than the plane containing the outer bottom surface of the pressure plate; the outer diameter of the drive ring is smaller than the width of the strip hole.

[0010] Furthermore, each of the side pressure rods is threaded with a screw at its center. One end of the screw is rotatably connected to the pressure plate on the same side, and the other end is connected to a rotating plate. Each side pressure rod has through holes at its front and rear. Each through hole has a limiting rod. One end of each limiting rod is fixedly connected to the pressure plate on the same side, and the other end passes through the corresponding through hole.

[0011] Furthermore, the bottom surface of each of the side pressure rods is flush with the outer bottom surface of the pressure plate; and an elastic pad is provided on the outer bottom surface of each pressure plate and the outer bottom surface of each side pressure rod.

[0012] The beneficial effects of this utility model through the above technical solution are as follows:

[0013] This invention uses a rotating drive rod to make two pressure plates move relative to each other or in opposite directions, thereby enabling the two pressure plates to adapt to pole groups ranging from narrow to wide. It has a wide range of applications, is easy to adjust, and ensures that the left and right sides of the pole group can be stressed evenly, making it easier for the pole group to be inserted into the slot.

[0014] This invention, by adjusting the distance between the side pressure rod and the same-side pressure plate, can prevent the electrode tabs of the electrode group from being subjected to top pressure and avoid damage. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0020] like Figures 1-3As shown, a battery terminal group insertion tooling includes a support plate 1, a pressure plate 2, and a side pressure rod 3. The support plate 1 is a rectangular plate, and there are two pressure plates 2, each U-shaped. The two pressure plates 2 are slidably locked onto the left and right sides of the support plate 1, respectively. A strip-shaped hole 4 is provided in the middle of the support plate 1. The strip-shaped hole 4 is a rectangular hole opened along the width direction of the support plate 1. A drive rod 5 is rotatably connected between the left and right sides of the strip-shaped hole 4. The drive rod 5 is a round rod, and a drive ring is fixedly fitted around the middle of the drive rod 5. 6. External threads 7 and 8 are respectively provided on the peripheral walls of the drive rods 5 on the left and right sides of the drive ring 6. The threads of external threads 7 and 8 are opposite in direction. Connecting plates 9 are threaded to the drive rods 5 on both sides of the drive ring 6. Each connecting plate 9 is slidably disposed in the strip hole 4. The connecting plate 9 is a rectangular plate that slides in contact with the strip hole 4 on the front and rear sides. The upper and lower ends of each connecting plate 9 are connected to the upper and lower inner surfaces of the pressure plate 2 on the same side. Side pressure rods 3 are provided on the opposite sides of the two pressure plates 2. Each side pressure rod 3 is driven by the screw 10 to move closer to or away from the pressure plate 2 on the same side.

[0021] The upper and lower inner surfaces of each pressure plate 2 are respectively in sliding contact with the upper and lower surfaces of the bearing plate 1; the front and rear of the top surface of the bearing plate 1 between the two pressure plates 2 are connected by connecting rods 11.

[0022] The two connecting plates 9 are symmetrical about the middle of the drive rod 5. The left connecting plate 9 is provided with a threaded hole 12 that corresponds to the external thread 7, and the right connecting plate 9 is provided with a threaded hole 13 that corresponds to the external thread 8.

[0023] The driving ring 6 is a circular ring, and the lower end of the driving ring 6 is higher than the plane where the outer bottom surface of the pressure plate 2 is located; the outer diameter of the driving ring 6 is smaller than the width of the strip hole 4.

[0024] Each of the side pressure rods 3 is threaded with a screw 10 at its middle. One end of the screw 10 is rotatably connected to the pressure plate 2 on the same side, and the other end is connected to a rotating plate 14. Each side pressure rod 3 has a through hole 16 at its front and rear. Each through hole 16 has a limiting rod 15 inside it. One end of each limiting rod 15 is fixedly connected to the pressure plate 2 on the same side, and the other end passes through the corresponding through hole 16.

[0025] The bottom surface of each of the side pressure rods 3 is flush with the outer bottom surface of the pressure plate 2; each of the outer bottom surfaces of the pressure plate 2 and each of the side pressure rods 3 is provided with an elastic pad 17, which is a sheet made of elastic rubber.

[0026] In use, this utility model is connected to a drive device via a connecting rod 11, which drives the utility model to move upward or downward. The drive device is located on the slotting mechanism. When a wide pole group needs to be pressed, the drive ring 6 is rotated, and the drive rod 5 rotates with the drive ring 6. When the drive rod 5 rotates, since the external threads 1 7 and external threads 2 8 on the left and right sides of the drive rod 5 rotate in opposite directions, the rotation of the drive rod 5 can drive the two connecting plates 9 to move in opposite directions. The two pressure plates 2 move in opposite directions with the connecting plates 9 they are connected to, until the distance between the opposite sides of the two side pressure rods 3 matches the width of the pole group. Then, the rotation of the drive ring 6 is stopped, and the screw 10 is rotated. Since the two ends of the side pressure rods 3 are limited, the screw 10 is rotated. When the side pressure rod 3 moves away from or towards the same-side pressure plate 2, the position of the side pressure rod 3 is adjusted according to the position of the electrode lugs of the electrode group as needed, so that the distance between the side pressure rod 3 and the same-side pressure plate 2 is directly above the electrode lugs. This allows the electrode lugs on the electrode group to pass between the side pressure rod 3 and the pressure plate 2 when the electrode group is pressed, without causing pressure damage to the electrode lugs. Similarly, rotating the drive ring 6 in the opposite direction allows the two pressure plates 2 to move relative to each other. The two pressure plates 2 can adapt to narrow electrode groups, and the present invention has a wide range of applications. Moreover, the outer bottom surface of each pressure plate 2 and the outer bottom surface of each side pressure rod 3 are provided with elastic pads 17, which will not cause pressure damage to the electrode group.

However, the present utility model is not limited to the above embodiments. Any equivalent or equivalent modifications or substitutions to the technical solutions of the present utility model without departing from the spirit of the present utility model or the scope of disclosure shall fall within the protection scope of the present utility model.
