Description

Technical Field

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

[0002] Lithium-ion battery surface screening equipment is widely used in all stages of lithium-ion battery production, including cell manufacturing, module assembly, and finished product inspection. In the cell manufacturing stage, the equipment is used to detect surface defects and dimensional accuracy of the cells; in the module assembly stage, it is used to ensure the cleanliness of the battery surface and the accuracy of markings; and in the finished product inspection stage, it is used for final quality control.

[0003] Existing lithium battery surface screening devices mainly collect information through high-definition camera components, and then analyze and judge the quality of the batteries through external analysis devices, and then classify them. However, the existing equipment often performs multiple operations such as detection and sorting separately, and requires manual intervention. This not only requires multiple operating machines to cooperate, but also generates a lot of labor costs. 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 existing equipment often involves multiple separate operations such as inspection and sorting, requiring manual intervention. This not only necessitates the coordination of multiple operating machines but also incurs significant labor costs. This utility model achieves the above objective through the following technical solution:

[0005] A device for screening the surface of cylindrical batteries includes: a housing, an electric telescopic rod, a support device, a drive device, a first camera acquisition device, a second camera acquisition device, a second elastic telescopic rod, a second push plate, and a falling guide plate. The support device includes a fixed plate, a rotating plate, a rack, a first push plate, and push rods. The fixed plate is connected to the output end of the electric telescopic rod. The rotating plate is rotatably mounted on the fixed plate. Two racks are located on both sides of the fixed plate. The first push plate is mounted on the fixed plate via a connecting rod. Two push rods are located on one side of the second elastic telescopic rod. The drive device includes a power block, a gear, the first elastic telescopic rod, and a balance frame. The power block meshes with the rack via the gear. The balance frame is located at the top of the first elastic telescopic rod. The first camera acquisition device is located on the inner wall of the housing. Two second cameras are symmetrically arranged at both ends of the battery. The second elastic telescopic rod is linked to the second push plate. The falling guide plates are symmetrically distributed on both sides of the drive device.

[0006] Preferably, the surface of the power block has a frosted texture, and it is driven by friction when in contact with the battery.

[0007] Preferably, a rotating rod is provided at the central axis of the power block, and the rotating rod is mounted on the inner wall of the outer casing via a rotating bearing.

[0008] Preferably, there are two elastic telescopic rods, which are vertically set on the inner wall of the outer casing via a connecting rod.

[0009] Preferably, the falling guide plate is divided into two groups, which tilt to the left and right respectively to guide the sorting of qualified and defective batteries.

[0010] This utility model uses an electric telescopic rod to drive a fixed plate to move toward the second elastic telescopic rod, which in turn drives a rack to move. The movement of the rack drives the power block to rotate, thereby causing the battery on it to rotate. During this process, the first camera acquisition device completes data acquisition from the side of the battery, and the second camera acquisition device completes data acquisition from both ends.

[0011] This utility model controls the collision between the push plate 2 or push plate 1 and the battery by controlling the different states of the electric telescopic rod. The whole process is guided by an active drive component, which avoids the problem that existing equipment often separates multiple operation steps such as detection and sorting, and requires manual intervention. This not only requires the cooperation of multiple operating machines, but also generates a lot of labor costs.

[0012] This utility model, through the coordinated movement of the electric telescopic rod and the elastic telescopic rod II, can not only limit the battery's descent process, but also drive the battery to rotate and sort the batteries according to their type. Attached Figure Description

[0019] like Figure 1-3 As shown, a device for screening the surface of cylindrical batteries includes: a housing 100, an electric telescopic rod 200, a support device 300, a drive device 400, a camera acquisition device 500, a guide frame 600, an elastic telescopic rod 700, a push plate 800, a camera acquisition device 900, a battery 1000, and a falling guide plate 1100.

[0020] The electric telescopic rod 200 is installed on the inner wall surface of the outer casing 100;

[0021] The support device 300 is installed on the output end of the electric telescopic rod 200;

[0022] The drive device 400 is rotatably mounted on the inner wall of the housing 100 via a rotary bearing;

[0023] The camera acquisition device 500 is installed on the inner wall of the outer casing 100 and mainly serves to collect information from the side of the battery 1000.

[0024] The guide frame 600 is located on the upper part of the outer casing 100 and mainly serves to guide the battery 1000 to fall to the designated position.

[0025] The second elastic telescopic rod 700 is disposed on the inner wall of the outer casing 100, and the second elastic telescopic rod 700 always has a driving force in the direction of the electric telescopic rod 200.

[0026] There are two push plates 800, which are set on the output end of the elastic telescopic rod 700 via a connecting rod.

[0027] There are two camera acquisition devices 900, which are set on the inner wall of the outer casing 100 via connecting rods. The camera acquisition devices 900 are located at both ends of the battery 1000 and can collect information from both ends of the battery 1000.

[0028] There are four falling guide plates 1100, which are divided into two groups and symmetrically arranged on both sides of the drive device 400. The falling guide plate 1100 on the left side is tilted to the left and the one on the other side is tilted to the right. The falling guide plate 1100 mainly guides the battery 1000 to fall, so that the battery 1000 can fall accurately into the designated collection box.

[0029] like Figure 3 As shown, the support device 300 includes: a fixed plate 310, a rotating plate 320, a rack 330, a push plate 340, and a push rod 350;

[0030] The fixing plate 310 is installed on the output end of the electric telescopic rod 200;

[0031] The rotating plate 320 is rotatably mounted on the fixed plate 310, and the rotating plate 320 has a built-in motor that can control the rotation state of the rotating plate 320.

[0032] There are two racks 330, which are arranged on both sides of the fixing plate 310;

[0033] The push plate 340 is mounted on the fixed plate 310 via a connecting rod;

[0034] There are two push rods 350, which are set on the side of the fixed plate 310 near the second elastic telescopic rod 700. The push rods 350 are always in contact with the second push plate 800.

[0035] like Figure 3-4 As shown, the drive device 400 includes: a power block 410, a gear 420, an elastic telescopic rod 430, and a balance frame 440;

[0036] A rotating rod is provided at the central axis of the power block 410, and the rotating rod is set on the inner wall of the outer shell 100 through a rotating bearing; the surface of the power block 410 is provided with a frosted texture, which can increase the friction force when driving the battery 1000 to rotate.

[0037] The number of gears 420 is two, which are set on the rotating rod of the power block 410. A one-way rotating bearing is provided between the gears 420 and the rotating rod so that the rotation direction of the gears 420 driving the rotating rod is fixed.

[0038] There are two elastic telescopic rods 430, which are vertically set on the inner wall of the outer shell 100 via connecting rods;

[0039] The balance frame 440 is mounted on the top of the elastic telescopic rod 430.

[0040] Working principle of this utility model:

[0041] In practice, the operator lowers the battery 1000 onto the balance frame 440 via the guide frame 600. During the descent, the rotating plate 320 and the push plate 800 are vertically upward, which helps to limit the descent of the battery 1000. After the battery 1000 falls onto the balance frame 440, it will press down on the elastic telescopic rod 430. During this process, the elastic telescopic rod 430 can buffer the descent of the battery 1000. At the same time, the elastic telescopic rod 430, when compressed and contracted, will send a signal to the rotating plate 320 via an external controller, causing it to rotate towards the electric telescopic rod 200 to a near-horizontal position.

[0042] Then, the electric telescopic rod 200 drives the fixed plate 310 to move toward the elastic telescopic rod 700, which in turn drives the rack 330 to move. The movement of the rack 330 drives the gear 420 to rotate, which in turn drives the power block 410 to rotate. The rotation of the power block 410 causes the battery 1000 on it to rotate. During this process, the camera acquisition device 500 completes the data acquisition of the side of the battery 1000, and the camera acquisition device 900 completes the acquisition of data from both ends.

[0043] After data acquisition, the external controller determines the condition of battery 1000. When battery 1000 is functioning correctly, the electric telescopic rod 200 retracts, and the pusher plate 800 moves towards the elastic telescopic rod 700, colliding with battery 1000 and squeezing it out from the balance frame 440. The battery then falls through the guide plate 1100 into an external collection box. Conversely, if battery 1000 has a problem, the electric telescopic rod 200 extends, and the pusher plate 340 moves towards the elastic telescopic rod 700, colliding with battery 1000 and squeezing it out from the balance frame 440. The battery then falls through the guide plate 1100 on the other side into another external collection box. The entire process is guided by an active drive component, the electric telescopic rod 200, avoiding the problems of existing equipment where multiple steps such as detection and sorting are often performed separately and require manual intervention. This not only requires multiple operating machines to cooperate but also incurs significant labor costs.

[0044] The coordinated movement between the electric telescopic rod 200 and the elastic telescopic rod 700 can not only limit the falling process of the battery 1000, but also drive the battery 1000 to rotate and sort the battery 1000 according to its category.
