Description

Technical Field

[0001] This utility model relates to the field of lithium battery manufacturing equipment, and in particular to a device for screening surface defects in a large number of lithium batteries. Background Technology

[0002] Lithium-ion battery surface screening equipment can be broadly categorized into manual inspection equipment and automated inspection equipment. Manual inspection equipment relies on operator visual inspection and simple tools, offering high flexibility but relatively low efficiency. Automated inspection equipment, on the other hand, employs machine vision, laser measurement, and artificial intelligence technologies, enabling high-speed, high-precision inspection and making it suitable for large-scale production.

[0003] While existing lithium battery surface screening processes can acquire surface images using cameras and then use artificial intelligence for judgment to complete the screening, each operation usually involves only one object and cannot collect images continuously, resulting in low efficiency. When testing a large number of batteries, multiple machines are often required to perform the tests simultaneously, increasing machine costs. Utility Model Content

[0004] Therefore, this utility model was made in view of the above problems. The purpose of this utility model is to solve the problem that, although the existing lithium battery surface screening process can acquire surface images through a camera and then judge them through artificial intelligence to complete the screening, only one object is operated at a time, which makes the efficiency low. When testing a large number of batteries, multiple machines are often required to perform the test simultaneously, which increases the machine cost. This utility model achieves the above objective through the following technical solution:

[0005] A device for screening surface defects of a large number of lithium batteries includes: a base plate, a shell, an information collector 1, an information collector 2, a drive device, a friction block, a sponge block, and a fixing block. The drive device includes a motor, a gear 1, a gear 2, a fan, and a gear ring. The motor drives the gear 1 to rotate. The gear 1 meshes with two gears 2. The fan is coaxially arranged with the gears 2. The gears 2 mesh with the inner tooth angle of the gear ring. The friction block is connected to the rotating shaft of the motor. The fixing block is fixed to the inner wall of the shell. The information collector 1 is arranged on both sides of the shell. The information collector 2 is arranged at both ends of the battery block. The sponge block is arranged on the outer tooth angle of the gear ring.

[0006] Preferably, there are two information collectors, symmetrically distributed on both sides of the fixed block, which collect complete surface information of both sides of the battery block through the gap.

[0007] Preferably, there are two information collectors, one of which is mounted on the drive device and the other is fixed to the inner wall of the outer casing, corresponding to the two ends of the battery block respectively.

[0008] Preferably, the bottom end of the fixing block is provided with an enlarged gap for the automatic falling and sorting of the battery blocks that have been tested.

[0009] Preferably, there are multiple sponge blocks, evenly distributed on the outer tooth corner of the toothed ring, which come into contact with the side of the battery block for cleaning as the toothed ring rotates.

[0010] Preferably, the friction block rotates in the opposite direction to the gear ring, the surface of the friction block is rough and contacts the battery block, driving the battery block to rotate.

[0011] This invention uses a friction block to contact the battery block and rotate in the opposite direction to the toothed ring. This causes the battery block to rotate under the influence of the friction block as it follows the toothed ring. Therefore, during the rotation of the battery block, the two information collectors can collect complete side information of the battery block by passing through the gap on the fixed block.

[0012] This invention features a sponge block that rotates and contacts the side of the battery block as the battery block rotates. This allows the sponge block to clean the side of the battery block, causing surface dust to slide off. During this process, the fan rotates to generate airflow that blows away the dust, thus achieving the purpose of cleaning the battery block and avoiding the problem of dust blocking surface information collection.

[0013] This invention allows operators to continuously insert battery blocks between the gear ring and the fixing block, increasing the capacity and timeliness of large-scale battery collection. It avoids the problems inherent in existing lithium battery surface screening processes, where only one object is typically selected per operation, leading to low efficiency. Furthermore, testing large numbers of batteries often requires multiple machines simultaneously, increasing machine costs. Attached Figure Description

Detailed Implementation

[0017] Preferred embodiments of this utility model will be described in detail with reference to the accompanying drawings, which will facilitate the implementation of these embodiments by those skilled in the art. However, this utility model can be implemented in various different forms, and therefore is not limited to the embodiments described below. Furthermore, for clarity, components not connected to this utility model will be omitted from the drawings.

[0018] like Figure 1-2 As shown, an apparatus for screening surface defects of a large number of lithium batteries includes: a base plate 100, a shell 200, an information collector 1 300, an information collector 2 400, a driving device 500, a friction block 600, a sponge block 700, a fixing block 800, and a battery block 900.

[0019] The outer casing 200 is mounted on the upper wall of the base plate 100 via a connecting rod;

[0020] The information collector 300 consists of two units, which are connected by a connecting rod and installed on both sides of the outer casing 200. They mainly pass through the gap in the fixing block 800 to collect information from the side of the battery block 900.

[0021] There are two information collectors 400, one of which is installed on the drive device 500 and the other is installed on the inner wall of the outer casing 200. The two information collectors 400 are located at both ends of the battery block 900 and mainly function to collect information from both ends of the battery block 900.

[0022] The drive device 500 is mounted on the housing 200;

[0023] The friction block 600 is mounted on the rotating shaft of the motor 510, and the two rotate in the same direction; the friction block 600 has a rough surface and can contact the battery block 900.

[0024] More than 700 sponge blocks are arranged on the outer tooth corner of the toothed ring 550, which can contact the battery block 900 to clean the dust on its surface during specific implementation;

[0025] The fixing block 800 is fixedly installed on the inner wall of the outer shell 200. The fixing block 800 has multiple gaps, and a larger gap is provided at its bottom end to allow the battery block 900 to fall.

[0026] like Figure 2 As shown, the drive device 500 includes: a motor 510, a first gear 520, a second gear 530, a fan 540, and a gear ring 550;

[0027] The motor 510 is rotatably mounted on the housing 200 via a connecting rod;

[0028] The gear 520 is mounted on the rotating shaft of the motor 510;

[0029] The number of gears 530 is two, which mesh with gear 520 and gear ring 550, and their rotation shaft is rotatably mounted on the outer casing 200.

[0030] There are two fans 540, which are respectively mounted on two gears 530;

[0031] The inner tooth angle of the gear ring 550 meshes with the gear 2 530, and the inner tooth angle can be used to support the battery block 900.

[0032] Working principle of this utility model:

[0033] In practice, the operator continuously inserts battery block 900 into... Figure 1 The motor 510 is positioned between the gear ring 550 on its right side and the fixed block 800. The motor 510 rotates, driving gear one 520 to rotate. Gear one 520, in turn, drives gear ring 550 to rotate via gear two 530. The rotation of gear ring 550 then drives battery block 900 to rotate. Figure 1 Rotate counterclockwise in the specified state;

[0034] As the battery block 900 rotates with the gear ring 550, the friction block 600 also rotates clockwise under the drive of the motor 510. The friction block 600 contacts the battery block 900 and rotates in the opposite direction to the gear ring 550. This causes the battery block 900 to rotate on its own under the drive of the friction block 600 as it rotates with the gear ring 550.

[0035] Therefore, during the rotation of the battery block 900 following the gear ring 550, the two information collectors 300 can completely collect the side information of the battery block 900 through the gap between the fixed blocks 800; at the same time, the two information collectors 300 are positioned on both sides of the fixed blocks 800, and in specific implementation, they can collect the side information of the battery block 900 inside one side of the fixed block 800 through the gap between the fixed blocks 800, which ensures that the information collectors 300 can collect information during the rotation of the battery block 900 around the friction block 600;

[0036] Complete side information of battery block 900 is collected through the gap on the fixed block 800; at the same time, the two information collectors 400 can collect information from both ends of battery block 900 during this period.

[0037] As the battery block 900 rotates with the gear ring 550, the sponge block 700 rotates and contacts the side of the battery block 900, allowing the sponge block 700 to clean the side of the battery block 900 and allow surface dust to slide off. During this process, gear 1 520 drives gear 2 530 to rotate, and the rotation of gear 2 530 drives the fan 540 to rotate, creating airflow that blows away the dust, thus cleaning the battery block 900 and preventing dust from obstructing surface information collection. After the data collection is completed, the battery block 900 rotates with the gear ring 550 and finally falls from the bottom of the fixed block 800 through a large gap for sorting.

[0038] Meanwhile, throughout the entire acquisition process, the operator can continuously insert the battery block 900 between the toothed ring 550 and the fixing block 800 without interruption. This increases the capacity and timeliness of acquiring a large number of batteries, avoiding the problems of existing lithium battery surface screening processes. Although surface images can be acquired by cameras and then judged by artificial intelligence to complete the screening, there is often only one object per operation, which makes the efficiency low. When testing a large number of batteries, multiple machines often need to be used simultaneously, which increases the machine cost.
