Description

Technical Field

[0001] This utility model relates to the field of battery casing processing technology, specifically a battery casing sheet metal laser processing mechanism. Background Technology

[0002] Currently, most laser welding of batteries involves manually pressing the battery caps to ensure a tight fit with the battery. This method is inefficient for mass production, has a low pass rate, easily generates scrap, is labor-intensive, has low work efficiency, and high production costs, which reduces the company's market competitiveness and hinders its rapid development. Furthermore, the battery casing is generally made of metal, which can easily cause short circuits when it comes into contact with metal clamps, making efficient production difficult.

[0003] The existing Chinese patent CN202861628U describes a laser welding auxiliary device for battery casings. However, when used to fix battery casings that are lower than the height of the cylinder, it cannot secure the battery, thus limiting its applicability. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, one of the objectives of this utility model is to provide a laser processing mechanism for battery casing sheet metal.

[0005] One of the objectives of this utility model is achieved through the following technical solution:

[0006] A sheet metal laser processing mechanism for battery casing includes a base plate, a cylinder fixedly connected to the top of the base plate near the center, a top plate fixedly connected to the power output end of the cylinder, a limit frame fixedly connected to the top of the base plate near the left side, a movable plate provided directly above the limit frame, a bearing fixedly connected to the top of the movable plate, a threaded rod fixedly inserted into the top of the bearing, a screw hole opened on the top of the top of the top plate near the left side, the top end of the threaded rod passing through the screw hole and fixedly connected to a rocker wheel.

[0007] Preferably, a limiting hole is provided on the top plate near the right side, and a guide post is movably provided through the inner cavity of the limiting hole, and the guide post is fixedly connected to the top of the bottom plate.

[0008] Preferably, a limiting plate is fixedly connected to the left side of the movable plate, and a limiting groove is formed on the left side of the top plate, with the limiting plate movably passing through the limiting groove.

[0009] Preferably, the threaded rod is threadedly connected to the threaded hole.

[0010] Preferably, a scale is provided on the left side of the limiting plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model discloses a sheet metal laser processing mechanism for battery casings. During use, if the height of the battery is less than the distance between the top of the movable plate and the bottom plate, the screw rod is rotated by the rocker wheel, and the screw rod drives the movable plate to move downward until the distance between the top of the movable plate and the bottom plate is less than the height of the battery. Then, the cylinder is controlled to drive the top plate and the movable plate to move downward. The downward movement of the movable plate presses and fixes the battery. By adjusting the height of the movable plate, this device can be used to fix batteries of different sizes, which greatly improves the adaptability of the device.

[0013] 2. The present invention relates to a sheet metal laser processing mechanism for battery casings. The setting of the scale allows the movable plate height to be recorded when the movable plate is adjusted to a suitable position for a battery of the corresponding size. This facilitates the subsequent resetting of the movable plate according to the recorded scale dimensions when processing batteries of different sizes.

[0014] The above description is merely an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this utility model more apparent and understandable, preferred embodiments are described below in detail with reference to the accompanying drawings.

[0022] Please see Figure 1-3 This utility model provides a technical solution: a battery shell sheet metal laser processing mechanism, including a base plate 1, a cylinder 2 fixedly connected to the top of the base plate 1 near the center position, a top plate 3 fixedly connected to the power output end of the cylinder 2, a limit hole 5 opened on the top plate 3 near the right side, a guide post 4 movably passing through the inner cavity of the limit hole 5, and the guide post 4 fixedly connected to the top of the base plate 1.

[0023] A limiting frame 6 is fixedly connected to the top of the base plate 1 near the left side. A movable plate 7 is located directly above the limiting frame 6. A limiting plate 8 is fixedly connected to the left side of the movable plate 7. A limiting groove 9 is opened on the left side of the top plate 3. The limiting plate 8 moves through the limiting groove 9. A bearing 11 is fixedly connected to the top of the movable plate 7. A threaded rod 13 is fixedly inserted into the top of the bearing 11. A screw hole 12 is opened on the top of the top of the top plate 3 near the left side. The top end of the threaded rod 13 passes through the screw hole 12 and is fixedly connected to a rocker wheel 14. The threaded rod 13 is threadedly connected to the screw hole 12. A scale 10 is opened on the left side of the limiting plate 8.

[0024] Working Principle: This utility model discloses a sheet metal laser processing mechanism for battery casings. During use, the cylinder 2 is first controlled to move the top plate 3 and the movable plate 7 downwards, so that the cylinder 2 is in its original length state. Then, the height of the movable plate 7 is adjusted according to the height of the battery. If the height of the battery is less than the distance between the movable plate 7 and the top of the bottom plate 1, the rocker wheel 14 drives the threaded rod 13 to rotate. The threaded rod 13 rotates in the inner cavity of the screw hole 12 and the bearing 11. Under the action of the thread, the threaded rod 13 moves downwards, which drives the movable plate 7 to move downwards. The movable plate 7 drives the limiting plate 8 to move in the inner cavity of the limiting groove 9 until the distance between the movable plate 7 and the top of the bottom plate 1 is less than the height of the battery. Then, the rocker wheel 14 is stopped rotating. After that, the cylinder 2 is first controlled to move the top plate 3 and the movable plate upwards. Then, the battery is first placed in the inner cavity of the limiting frame 6. Then, the cylinder 2 is first controlled to move the top plate 3 and the movable plate 7 downwards. The movable plate 7 moves downwards to press and fix the battery. After that, sheet metal laser welding is performed on the battery casing.

[0025] If the height of the battery is greater than the distance between the top of the movable plate 7 and the bottom plate 1, there is no need to adjust the height of the movable plate 7.

[0026] By adjusting the height of the movable plate 7, the device can be used to fix batteries of different sizes, greatly improving its adaptability.

[0027] The scale 10 allows the height of the movable plate 7 to be recorded when the corresponding size battery is adjusted to a suitable position. This makes it convenient for the movable plate 7 to be reset according to the recorded scale dimensions when processing batteries of different sizes in the future.
