Abstract
Description
Technical Field
[0001] This utility model relates to the technology of removing impurities before sealing a storage battery, specifically to a storage battery impurity removal device. Background Technology
[0002] In the manufacturing process of batteries, the precision of the assembly process plays a crucial role in battery quality. Among these processes, the internal cleaning procedure before the battery cover is closed is particularly important, especially the removal of impurities from the separator area, which is a core step in preventing battery short circuits and extending battery life.
[0003] Battery separators are typically made of porous materials. Their main function is to isolate the positive and negative plates, preventing direct contact and short circuits, while allowing electrolyte to freely permeate for ion conduction. However, various impurities are inevitably generated during battery assembly. If these impurities remain on the separator surface or in the pores, they may puncture the separator's insulation layer, causing partial conductivity between the positive and negative plates and triggering a short circuit. Short circuits not only cause battery capacity degradation and unstable energy output, but in severe cases, they can also lead to overheating, leakage, and other quality problems.
[0004] Currently, the cleaning method mainly relies on manual operation, which is inefficient, inconsistent, and difficult to effectively remove impurities, resulting in the continued risk of residual impurities.
[0005] Based on this, this utility model was designed for the automated removal of impurities from semi-finished batteries. Summary of the Invention
[0006] This utility model proposes a battery impurity removal device, which is installed between the front conveyor belt of the battery semi-finished product conveying device and the top cover installation station. It can automatically remove impurities from the battery semi-finished product, improving efficiency and effectively removing impurities.

[0008] The battery clamping fixture includes a base plate, with a left side plate fixed to one end and a right side plate fixed to the other end. The left side of the left side plate is fixedly connected to the output shaft of the rotary motor. A horizontal cylinder is fixedly installed on the base plate, and the piston rod of the horizontal cylinder is fixedly connected to a movable clamping plate. The movable clamping plate and the right side plate form a clamping assembly for clamping the battery.
[0009] An impurity collection device is provided below the battery clamping fixture.

[0012] Based on the above scheme, as a preferred option, flexible pads are fixedly installed on the opposite surfaces of the movable clamping plate and the right side plate.

[0018] By designing a combination of a rotary motor, a battery clamping fixture, and an impurity collection device, impurities can be quickly removed from the semi-finished battery, preventing impurities from remaining inside the finished battery and causing internal short circuits.
[0019] Flexible pads are fixedly installed on the opposite surfaces of the movable clamp and the right side plate to increase the friction when clamping the battery.
[0020] The cooperation between the guide sleeve and the guide rod increases the contact area of the guiding part, thereby ensuring the stability of the guide and improving its service life.

[0023] Figure 1 This is a schematic diagram of the structure of this utility model;
[0024] Figure 2 This is a schematic diagram showing the interaction between this utility model and the semi-finished product conveying device and the front-end conveyor belt; Detailed Implementation
[0025] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort. Example
[0026] like Figure 1-2 As shown, a battery cleaning device includes a rotary motor worktable 1, a rotary motor 2 fixedly mounted on the rotary motor worktable, an output shaft 3 of the rotary motor fixedly connected to one end of a battery clamping fixture, and a bracket 9 rotatably connected to the other end of the battery clamping fixture.
[0027] The battery clamping fixture includes a base plate 4, with a left side plate 5 fixed to one end of the base plate and a right side plate 6 fixed to the other end. The left side of the left side plate is fixedly connected to the output shaft of the rotary motor, and a connecting shaft 7 is fixedly connected to the right end of the right side plate. The connecting shaft is rotatably connected to a bearing 8 on a bracket.
[0028] A middle plate 10 is fixedly installed on the base plate. A horizontal cylinder 11 is fixedly installed on the base plate between the middle plate and the left side plate. The piston rod of the horizontal cylinder passes through the middle plate and is fixedly connected to a movable clamping plate 12. The movable clamping plate and the right side plate form a clamping assembly for holding the battery. Flexible pads 13 are fixedly installed on the opposite surfaces of the movable clamping plate and the right side plate to increase the friction when clamping the battery.
[0029] The movable clamping plate has a gap between it and the base plate. To ensure the movable clamping plate does not deform during long-term use and to improve its service life, at least two guide sleeves 14 are fixedly installed on the left side of the intermediate plate. The left side plate of the movable clamping plate is fixedly installed with the same number of guide rods 15 as the guide sleeves. The guide rods pass through the guide sleeves and slide in cooperation with them. There is no need to design a guide structure between the movable clamping plate and the base plate, such as a guide groove on the base plate or a guide rail on the movable clamping plate. Such guide structures affect the strength of the base plate, are relatively complex to manufacture, and have a small mating area between the groove and the guide rail, which is not conducive to the long-term use of the equipment.
[0030] An impurity collection device is provided below the battery clamping fixture, and the distance between the impurity collection device and the base plate is at least enough not to interfere with the flipping of the base plate.
[0031] The impurity collection device includes a base frame 16, a lifting cylinder 17 fixedly mounted on the base frame, a support frame 18 whose piston rod is fixedly connected to the lifting cylinder, a collection hopper 19 mounted on the support frame, and a flexible rubber 20 fixedly mounted around the upper end of the collection hopper. An exhaust fan 21 is installed inside the support frame, and the exhaust fan's inlet pipe 22 extends into the collection hopper. Wheels are installed at the bottom of the base frame.
[0032] This utility model is applied in the process of initially assembling a storage battery (semi-finished product) and before installing the top cover, specifically between the semi-finished product conveying device 28 and the front conveyor belt 25 of the top cover installation station.
[0033] During use, the semi-finished battery 27 is pushed into the base plate by the drive cylinder 26 on the semi-finished product conveying device. The horizontal cylinder drives the movable clamping plate to clamp the semi-finished battery tightly against the right side plate. The rotary motor starts, and the battery clamping fixture rotates 180 degrees. The lifting cylinder drives the collection bucket to move upward. The rubber on the collection bucket presses against the movable clamping plate, the right side plate, and the battery casing. The exhaust fan draws air, and impurities in the semi-finished battery (especially impurities on the separator) fall into the collection bucket under the action of gravity and the suction of the exhaust fan. The lifting cylinder resets, the rotary motor resets, the horizontal cylinder resets, and the drive cylinder pushes the battery onto the front conveyor belt. The drive cylinder resets again.
[0034] The movable clamp is at the same height as the right side plate. Two batteries are grouped together, and there can be a slight gap between the rubber and the battery casing, as long as it does not affect the generation of suction. Example
[0035] Based on Embodiment 1, in order to avoid the problem that some impurities on the partition cannot be sucked out by suction alone, a blower 23 is installed in the support frame. The blower's air supply pipe extends into the collection hopper 24. The blower and the exhaust fan are connected by a NOT gate circuit and can also work independently.
[0036] In use, the semi-finished battery is pushed onto the base plate by the drive cylinder on the semi-finished product conveying device. The horizontal cylinder drives the movable clamping plate to hold the semi-finished battery tightly against the right side plate. The rotary motor starts, and the battery clamping fixture rotates 180 degrees. The lifting cylinder drives the collection hopper to move upward. The rubber on the collection hopper presses against the movable clamping plate, the right side plate, and the battery casing. The blower blows air into the battery casing for 2-3 seconds. Then, the lifting cylinder returns to its downward position and moves upward again, allowing the rubber on the collection hopper to press against the movable clamping plate, the right side plate, and the battery casing. The exhaust fan draws air, and impurities inside the semi-finished battery fall into the collection hopper under the action of gravity, the push of the blower, and the suction of the exhaust fan. The lifting cylinder, the rotary motor, and the horizontal cylinder return to their original positions. The drive cylinder pushes the battery onto the front conveyor belt, and the drive cylinder returns to its original position.
[0037] It should be noted that the above embodiments can be freely combined as needed. The above description is only a preferred embodiment of this utility model. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
