Description

Technical Field

[0001] This utility model relates to the field of lithium battery manufacturing equipment, and in particular to a convenient lithium battery surface defect screening device. Background Technology

[0002] The significance of surface screening for lithium batteries lies in improving product quality, enhancing safety, and reducing production costs. Through rigorous surface screening, defective batteries can be identified and rejected promptly, ensuring the quality of products leaving the factory and reducing customer complaints and returns. Simultaneously, surface screening also enhances battery safety, preventing safety hazards caused by surface defects.

[0003] Existing lithium battery surface screening processes often require manual judgment of the battery surface. This manual judgment process is not only time-consuming, but also causes eye fatigue due to prolonged manual work, and is prone to omissions. Utility Model Content

[0004] Therefore, this utility model was developed in view of the above problems. The purpose of this utility model is to solve the problem that the existing lithium battery surface screening process often requires manual judgment of the battery surface through the design of a nozzle that moves up and down. This manual judgment process is not only time-consuming, but also causes eye fatigue due to prolonged manual work, and is prone to omissions. This utility model achieves the above objective through the following technical solution:

[0005] A convenient lithium battery surface defect screening device includes: a base plate, a support, a collector 1, a rotating rod, a limiting plate, and an adjustment device. The adjustment device includes an electric telescopic rod, a drive block, a conversion block, a collector 2, and a power block. The electric telescopic rod is vertically mounted on the base plate. The inner rod of the electric telescopic rod is threaded and engages with the drive block. The drive block is fixed on the conversion block, which is rotatably mounted on the outer rod of the electric telescopic rod. The power block is connected to the top of the inner rod of the electric telescopic rod. There are two limiting plates, which are mounted on the support via the rotating rod. The collector 1 is positioned above and to the side of the limiting plate.

[0006] Preferably, the rotating rod has a built-in worm spring, so that the limiting plate always has a driving force to rotate toward the battery block.

[0007] Preferably, the inner side of the limiting plate is provided with a protrusion for fixing the position of the battery block.

[0008] Preferably, the protrusions of the limiting plate are made of elastic rubber to prevent the battery block from shifting when it rotates.

[0009] Preferably, the power block is driven to rotate by a motor, and the surface of the power block is provided with friction patterns. When the power block comes into contact with the battery block, it causes the battery block to rotate around its axis.

[0010] Preferably, the bracket is provided with a blocking plate to limit the maximum rotation angle of the limiting plate.

[0011] This utility model uses an electric telescopic rod to drive the power block to move down, so that its inner rod passes through the drive block and drives the drive block and the conversion block to rotate. The rotation of the conversion block causes the second collector on it to rotate to the other side of the battery block to complete the image acquisition.

[0012] This invention uses an electric telescopic rod to drive a power block to move battery blocks to the top or bottom of a limiting plate. After the battery blocks are released from the limiting plate, they can be sorted by the operator. This method is not only simple but also allows for quick sorting of battery blocks. At the same time, the entire process does not require employees to use their eyes for a long time, avoiding the time-consuming and visually tiring process of manual judgment, which is also prone to omissions.

Detailed Implementation

[0016] 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.

[0017] like Figure 1 As shown, a convenient lithium battery surface defect screening device includes: a base plate 100, a support 200, a collector 300, a rotating rod 400, a limiting plate 500, a blocking plate 600, an adjusting device 700, and a battery block 800.

[0018] The bracket 200 is disposed on the upper wall surface of the base plate 100;

[0019] The data collector 300 is mounted on the bracket 200 and located above the limiting plate 500. It is mainly used to collect data from the side of the battery block 800.

[0020] There are two rotating rods 400, which are rotatably mounted on the bracket 200. A worm spring is provided at the connection position between the rotating rod 400 and the bracket 200. Under the action of the worm spring, the rotating rod 400 always has a driving force to drive its upper limit plate 500 to rotate toward the battery block 800.

[0021] There are two limiting plates 500, which are respectively set on the two rotating rods 400 and located on both sides of the battery block 800 to support and limit the movement. The limiting plate 500 has multiple protrusions on the side near the battery block 800 to limit and keep the battery block 800 in the middle position between the two limiting plates 500.

[0022] There are two blocking plates 600, which are set on the bracket 200 and mainly serve to limit the maximum rotation angle of the limiting plate 500.

[0023] The adjustment device 700 is disposed on the upper wall surface of the base plate 100;

[0024] like Figure 2 As shown, the adjustment device 700 includes: an electric telescopic rod 710, a drive block 720, a conversion block 730, a collector 740, and a power block 750;

[0025] The electric telescopic rod 710 is vertically mounted on the upper wall of the base plate 100. The inner rod of the electric telescopic rod 710 is threaded so that it can engage with the drive block 720.

[0026] The drive block 720 is mounted on the conversion block 730 and engages with the electric telescopic rod 710.

[0027] The conversion block 730 is rotatably mounted on the outer rod of the electric telescopic rod 710;

[0028] The second data acquisition device 740 is mounted on the conversion block 730 and can acquire images from both ends of the battery block 800 in specific implementation.

[0029] The motor 760 is mounted on the top of the inner rod of the electric telescopic rod 710 via a connecting rod, and in specific implementation, it serves to drive the power block 750 to rotate.

[0030] One end of the power block 750 is mounted on the top of the inner rod of the electric telescopic rod 710 via a connecting rod, and the other end is connected to the output end of the motor 760. The surface of the power block 750 is provided with a pattern to increase friction. In specific implementation, the external controller can drive the power block 750 to rotate by controlling the motor 760, thereby driving the battery block 800 to rotate.

[0031] Working principle of this utility model:

[0032] First, the electric telescopic rod 710 drives the power block 750 upwards to the side of the bottom of the limiting plate 500. Then, the operator places the battery block 800 between the two limiting plates 500, so that the battery block 800 is limited between the two limiting plates 500, and its bottom contacts the power block 750. Figure 1 As shown;

[0033] Driven by the motor 760, the power block 750 rotates, causing the battery block 800 to rotate. Acquisition device 1 300 then captures images of the side of the battery block 800, while acquisition device 2 740 captures images of one side of the battery block 800. The electric telescopic rod 710 drives the power block 750 to move downward, and its inner rod passes through the drive block 720, causing the drive block 720 and the conversion block 730 to rotate. The rotation of the conversion block 730 causes acquisition device 2 740 on it to rotate to the other side of the battery block 800 to complete the image acquisition.

[0034] After the image acquisition is completed, when there is a problem with the battery block 800, the electric telescopic rod 710 drives the power block 750 to move upward, causing the battery block 800 to move upward above the limit plate 500. Then the battery block 800 is released from the limit plate 500, and the staff can take out the problematic battery block 800 and place it in the designated collection box.

[0035] When the battery block is fine, the electric telescopic rod 710 drives the power block 750 to move down, causing the battery block 800 to move down to below the limit plate 500. Then the battery block 800 is also released from the limit plate 500. After that, the staff can take out the battery block 800 that is fine and place it in another designated collection box.

[0036] This method is not only simple but also allows for quick sorting of battery blocks 800. At the same time, the entire process does not require employees to use their eyes for extended periods, avoiding the time-consuming and visually tiring process of manual judgment, which is also prone to omissions.
