Abstract
Description
Technical Field
[0001] This utility model relates to the field of automated assembly of lithium-ion cylindrical batteries, specifically to an online positioning carrier for cylindrical batteries. Background Technology
[0002] With the increasing demand for high-performance cylindrical batteries from new energy vehicles, energy storage systems, and portable electronic products, the automation, precision, and yield of battery assembly have become key factors restricting production capacity and quality. On a typical cylindrical battery assembly line, the wound bare cells need to pass through the following stages sequentially: 1. Welding station: Laser or hot-press welding is performed on the battery cell tabs to the busbar or end cap; 2. Insertion Station: Precisely insert the battery cell into the metal casing; 3. Sealing station: Mechanically press or rotate to lock the metal casing; 4. Testing station: Performs performance and safety tests on the packaged battery, including charge / discharge, leakage, and airtightness.
[0003] In all the aforementioned workstations, the positioning and fixing of the battery cells are prerequisites for ensuring accurate solder joints, tight packaging, and stable testing. Currently, production lines often use universal positioning carriers composed of upper and lower clamps, side plates, or soft sponges. However, these traditional solutions have the following main shortcomings: 1. Insufficient positioning accuracy: The carrier size is loosely matched with the cell diameter, which can easily cause radial or axial offset, resulting in misalignment of the electrode welding, jamming or tilting of the housing insertion, and affecting the subsequent capping quality.
[0004] 2. Limited clamping methods: These methods rely heavily on top and bottom clamping or side single-point clamping, which cannot simultaneously constrain the minute vibrations and rotations of the battery cell in three degrees of freedom. Under high-speed production lines (cycle time ≤ 3s / piece), the battery cell shakes frequently, resulting in a high alignment failure rate.
[0005] 3. Poor automation adaptability: Traditional positioning carriers require manual replacement or adjustment to adapt to different specifications (such as 18650, 21700, 4680, etc.) of battery cells; the debugging cycle is long, the production line switching efficiency is low, and it is difficult to meet the flexible production needs of automotive grade or multiple models.
[0006] 4. Durability and cleanliness issues: Some soft or elastic materials are prone to aging and deformation under high temperature and high humidity conditions; at the same time, they are difficult to clean, causing dust or electrolyte residue to adhere to the surface of the clamp, affecting the cleanliness and safety of the battery.
[0007] Therefore, there is an urgent need for an online positioning carrier that can achieve rapid switching between multiple battery cell specifications, three-dimensional rigid constraints, high-speed and stable clamping, and resistance to high temperature and chemical corrosion, in order to meet the stringent requirements of modern battery production lines for assembly accuracy, automation level and production yield. Utility Model Content
[0008] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a cylindrical battery online positioning carrier that achieves high-precision positioning through bidirectional synchronous locking (horizontal + vertical), and has modular design, high efficiency and automation and stable reliability, which significantly improves the accuracy and efficiency of cylindrical battery assembly.
[0009] To achieve the above objectives, this utility model is implemented through the following technical solution: a cylindrical battery line positioning carrier, including a base and a carrier body, wherein a fixing plate is vertically arranged on the base, a first connecting plate is arranged on one side of the middle of the fixing plate through a support plate, a horizontal plate is arranged on the first connecting plate, the horizontal plate cooperates with a horizontal push block, the horizontal push block cooperates with the carrier body, a blocking block is arranged at the top of the fixing plate, a movable block is arranged below the blocking block, the movable block is connected to the lower positioning push block through a lower positioning push block fixing plate, and the lower positioning push block cooperates with the carrier body.
[0010] Preferably, the carrier body includes a base plate, one end of which is provided with a left clamping push rod that cooperates with a horizontal push block. The base plate is connected to a second connecting plate via a connecting block. The second connecting plate is connected to a transmission belt. The upper right end of the second connecting plate is connected to the bottom of the base plate via a pad. A battery limiting groove is provided on the base plate above the pad, and a cylindrical battery is provided in the battery limiting groove. A lower clamping push block is provided below the second connecting plate below the pad.
[0011] The beneficial effects of this utility model are: 1. The structure of this utility model is reasonable. Through the linkage design of the horizontal push block and the lower positioning push block, the cylindrical battery is rigidly fixed in both directions, reducing the positional deviation during the assembly process. It is suitable for high-precision automated production lines.
[0012] 2. The main body of the vehicle and the positioning mechanism are designed separately (such as adjustable fixing plates and support plates), which can be adapted to cylindrical batteries of different sizes. Only the limit groove or push block stroke needs to be adjusted.
[0013] 3. Seamlessly connects with chain conveyor belts and works with robotic arms for loading and unloading to achieve continuous assembly line operation and improve production efficiency.
[0014] 4. The mechanical limit design of the blocking block and the lower positioning push block fixing plate avoids overload damage to the battery; the flexible adjustment of the movable block can adapt to the battery tolerance. Attached Figure Description
[0015] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments; Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation
[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0017] Reference Figure 1 The specific embodiment adopts the following technical solution: a cylindrical battery line positioning carrier, including a base 1, a fixing plate 2 is vertically arranged on the base 1, a first connecting plate 4 is arranged on one side of the middle of the fixing plate 2 through a support plate 3, a horizontal plate 5 is arranged on the first connecting plate 4, the horizontal plate 5 cooperates with a horizontal push block 6, the horizontal push block 6 cooperates with the carrier body, a blocking block 7 is arranged at the top of the fixing plate 2, a movable block 8 is arranged below the blocking block 7, the movable block 8 is connected to the lower positioning push block 10 through a lower positioning push block fixing plate 9, and the lower positioning push block 10 cooperates with the carrier body.
[0018] It is worth noting that the main body of the carrier includes a base plate 11. A left clamping push rod 12 is provided at one end of the base plate 11. The clamping push rod 12 cooperates with the horizontal push block 6. The base plate is connected to the second connecting plate 14 via a connecting block 13. The second connecting plate 14 is connected to the transmission belt. The upper right end of the second connecting plate 14 is connected to the bottom of the base plate via a pad 15. A battery limiting groove is provided on the base plate above the pad 15. A cylindrical battery 16 is provided in the battery limiting groove. A lower clamping push block 17 is provided below the second connecting plate 14 below the pad 15.
[0019] The working principle of this specific embodiment is as follows: The carrier body (base plate 11) is connected to the chain conveyor belt via the second connecting plate 14 and is moved to the workstation by the conveyor belt. An external robot arm places the cylindrical battery 16 into the battery limiting groove of the carrier. At this time, the battery is initially fixed but not completely locked. When the carrier reaches the target workstation, the horizontal push block 6 on the fixing plate 2 pushes the left clamping push rod 12 of the carrier to the left, causing the base plate 11 to move to the left. Through the cooperation of the pad 15 and the battery limiting groove, the side of the cylindrical battery is clamped to prevent horizontal shaking. At the same time, the lower positioning push block 10 (driven by the movable block 8 and the lower positioning push block fixing plate 9) moves upward, pushing the lower clamping push block 17 of the carrier, so that the bottom of the battery limiting groove is in close contact with the cylindrical battery, avoiding vertical displacement.
[0020] The top blocking block 7 restricts the travel of the movable block 8, ensuring moderate positioning force and preventing excessive compression of the battery. The synchronized movement of the horizontal push block 6 and the lower positioning push block 10 achieves bidirectional locking of the battery (horizontal + vertical), ensuring assembly accuracy. After positioning is completed, the carrier is transported to the next station by a chain conveyor belt for subsequent operations (such as welding, inspection, etc.).

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
