Description

Technical Field

[0001] This utility model relates to the field of lithium battery manufacturing and transfer technology, and in particular to a feeding device for lithium battery production. Background Technology

[0002] Lithium-ion batteries, as high-performance energy storage devices, are widely used in new energy vehicles, consumer electronics, and energy storage systems. Their production involves the precision processing of various raw materials, including positive and negative electrode sheets, separators, and current collectors. Among these, wound electrodes need to be transferred between processes in a ring-shaped roll form. These materials are typically stacked in a hollow ring structure, requiring efficient and non-destructive automated transfer via a feeding device during production. This places extremely high demands on the stability and safety of the feeding process.

[0003] Currently, the industry commonly uses cylindrical forklift-type feeding equipment to transfer annular roll materials. The main body of this equipment is a vertically positioned cylindrical support shaft. During operation, a forklift or robotic arm drives the support shaft horizontally into the central hole of the annular roll material, using the contact between the outer wall of the cylindrical shaft and the inner hole of the roll material to support the material. To accommodate roll materials of different inner diameters, the equipment is usually equipped with retractable auxiliary supports or limiting baffles, but the core transfer function still relies on the physical contact between the cylindrical shaft and the roll material.

[0004] The existing cylindrical shaft feeding method has significant drawbacks: Dynamic sliding risk: The cylindrical shaft and the inner wall of the annular roll material are in line contact, resulting in limited frictional resistance. During start-up and shutdown or when the path is bumpy, the roll material is prone to sliding axially or even falling off, requiring frequent shutdowns for adjustment; reliance on manual intervention: To prevent slippage, operators must manually insert pins or locking pins through the roll material and support shaft after loading. This process is inefficient, and manual operation can easily lead to positioning errors; Safety and compatibility defects: The pin holes need to be precisely aligned with the inner hole of the roll material, making it sensitive to the material's orientation. Furthermore, the manual locking mode is difficult to adapt to the needs of high-speed automated production lines, posing a risk of personal injury and limiting the overall production capacity increase. Utility Model Content

[0005] To overcome the drawback of requiring manual pin insertion for axial sliding, this invention provides a stable feeding device for lithium battery production.

[0006] A feeding device for lithium battery production includes a feeder with a feeding arm. An electric slide rail is installed at the bottom rear end of the feeding arm. A pressure plate is connected to the top rear end of the feeding arm. A sliding block is slidably connected within the electric slide rail. A pressing block is connected to the top of the sliding block, and the top of the pressing block is slidably connected to the pressure plate. A fixing plate is connected to the front end of the feeding arm. A locking block is slidably connected to the front end of the feeding arm. A connecting frame is connected to the bottom of the locking block. Several springs are arranged between the fixing plate and the connecting frame. The front end of the pressing block is pressed against the connecting frame. A stabilizing component is provided on the feeder to restrict the sliding of the raw material.

[0007] In a preferred embodiment of this utility model, the stabilizing component includes a mounting frame, the rear end of the feeding arm is connected to the mounting frame, a limit plate is slidably connected to the feeding arm, one end of the mounting frame is threadedly connected to an adjusting screw, the front end of the adjusting screw is rotatably connected to the limit plate, and the other end of the mounting frame is slidably connected to a guide rod, the front end of the guide rod is fixedly connected to the limit plate.

[0008] In a preferred embodiment of this utility model, a sponge pad is connected to the front side of the limiting plate.

[0009] In a preferred embodiment of this utility model, graduated rings are evenly arranged on the guide rod.

[0010] In a preferred embodiment of this utility model, a plurality of rollers are rotatably connected to the middle of the connecting frame, and the extrusion block is rotatably connected to the rollers.

[0011] In a preferred embodiment of this utility model, a guide block is connected to the front end of the feeding arm.

[0012] Compared with the prior art, the present invention has the following advantages: 1. Through the linkage design of the locking block and the spring, when the feeding arm inserts the roll material, the locking block is squeezed inward to compress the spring. After the roll material has completely passed through, the spring automatically rebounds, pushing the locking block outward to form a mechanical stop, blocking its physical path of sliding along the axial direction of the feeding arm, thus achieving the purpose of stable transportation.

[0013] 2. Through the transmission cooperation between the electric slide rail and the extrusion block, when the electric slide rail drives the extrusion block to move horizontally forward, the downward pressure connecting frame forces the locking block to retract and unlock, triggering the locking block to reset, releasing the lock on the roll material, eliminating the manual pin operation step, and optimizing the feeding process.

Detailed Implementation

[0018] First, it should be noted that in different described embodiments, the same components are given the same reference numerals or the same component names. The disclosure contained throughout this specification can be applied semantically to the same components having the same reference numerals or the same component names. The location descriptions selected in the specification, such as upper, lower, lateral, etc., also refer to the directly described and illustrated figures and are semantically applied to the new location when the location changes.

[0019] Example: A feeding device for lithium battery production, such as... Figures 1-3 As shown, the assembly includes a feeder 1, a loading arm 2, an electric slide rail 3, a sliding block 4, a pressure plate 5, an extrusion block 6, a fixing plate 7, a spring 8, a connecting frame 9, a locking block 10, and a stabilizing component. The feeder 1 is equipped with a loading arm 2. Several guide wheels are rotatably connected to the outer wall of the front end of the loading arm 2 to reduce the frictional resistance with the inner wall of the roll material during insertion. An electric slide rail 3 is installed at the bottom of the rear end of the loading arm 2. A pressure plate 5 is connected to the top of the rear end of the loading arm 2. A sliding block 4 is slidably connected inside the electric slide rail 3. An extrusion block 6 is connected to the top of the sliding block 4. The top of the extrusion block 6 is slidably connected to the pressure plate 5, and the bottom of the sliding block 4 protrudes from the loading arm 2. At the bottom, when the electric slide rail 3 fails, the extrusion block 6 can be manually pushed by the sliding block 4. The front end of the feeding arm 2 is connected to the fixing plate 7, and the front end of the feeding arm 2 is slidably connected to the locking block 10. The bottom of the locking block 10 is connected to the connecting frame 9. Several springs 8 are set between the fixing plate 7 and the connecting frame 9. The front end of the extrusion block 6 is squeezed and engaged with the connecting frame 9. The feeder 1 drives the feeding arm 2 to insert into the center hole of the roll material. When inserted, the roll material squeezes the locking block 10 inward and compresses the spring 8 to store energy. After the roll material has completely passed through, the spring 8 rebounds and pushes the locking block 10 outward to form a mechanical limit. The feeder 1 is equipped with a stabilizing component to limit the sliding of the raw material.

[0020] like Figure 1 and Figure 3As shown, the stabilizing component includes a mounting frame 11, a guide rod 12, a limiting plate 13, and an adjusting screw 14. The mounting frame 11 is connected to the rear end of the feeding arm 2, and the limiting plate 13 is slidably connected to the feeding arm 2. The adjusting screw 14 is threadedly connected to one end of the mounting frame 11, and the front end of the adjusting screw 14 is rotatably connected to the limiting plate 13. The guide rod 12 is slidably connected to the other end of the mounting frame 11, and the front end of the guide rod 12 is fixedly connected to the limiting plate 13. Rotating the adjusting screw 14 pushes the limiting plate 13 to move axially, and the limiting plate 13 contacts the side of the roll material, forming a double-point clamping with the locking block 10.

[0021] like Figure 3 As shown, it also includes a sponge pad 15, and the front side of the limiting plate 13 is connected to the sponge pad 15, which is in flexible contact.

[0022] like Figure 3 As shown, it also includes a scale ring 16. The scale ring 16 is evenly arranged on the guide rod 12, and the displacement of the limit plate 13 is quantitatively displayed through the scale ring 16.

[0023] like Figure 2 As shown, it also includes rollers 17. Several rollers 17 are rotatably connected in the middle of the connecting frame 9. The pressing block 6 is rotatably connected to the rollers 17. The rollers 17 convert sliding friction into rolling friction.

[0024] like Figure 1 As shown, it also includes a guide block 18. The front end of the feeding arm 2 is connected to the guide block 18, and the guide block 18 guides the feeding arm 2 to insert into the center hole without deviation.

[0025] Workers control the feeding arm 2 to move up and down via the feeder 1. After the feeding arm 2 is aligned with the center hole of the raw material, the feeder 1 is pushed. Guided by the guide block 18, the feeding arm 2 inserts into the raw material. Then, the feeder 1 controller lifts the raw material. During the insertion of the feeding arm 2 into the raw material, the locking block 10 at the front end of the feeding arm 2 is squeezed by the raw material. The inner wall of the roll radially squeezes the locking block 10, forcing the locking block 10 to slide radially inward along the feeding arm 2. Several springs 8 are compressed by the connecting frame 9. When the raw material has completely passed through the locking block 10, the springs 8 rebound, pushing the connecting frame 9 and the locking block 10 to move upward. The part of the locking block 10 that protrudes from the feeding arm 2 restricts the sliding of the raw material, thereby limiting the slippage of the raw material during movement and ensuring the stability and safety of the transportation process.

[0026] When material needs to be unloaded, the operator activates the electric slide rail 3, which drives the sliding block 4 and the extrusion block 6 to slide forward. The extrusion block 6 is restricted by the pressure plate 5, so that when the front end of the extrusion block 6 extrudes the connecting frame 9, it can still maintain a fixed height. The extrusion block 6 presses down the connecting frame 9, compressing all the springs 8, and by driving the locking block 10 to slide down, it releases the restriction on the material sliding out of the feeding arm 2, and the material is unloaded. When the extrusion block 6 extrudes the connecting frame 9, the roller 17 contacts the extrusion block 6, changing the sliding friction into the rolling friction of the roller 17, reducing the frictional resistance.

[0027] For raw materials of different widths, in order to further restrict the slippage of the raw materials, the operator rotates the adjusting screw 14. The adjusting screw 14 pushes the limiting plate 13 to slide on the feeding arm 2 through the threaded connection with the mounting frame 11. The guide rod 12 connected to the other end of the limiting plate 13 slides in the mounting frame 11 to ensure the stability of the limiting plate 13. After the limiting plate 13 moves, the sponge pad 15 contacts the end face of the roll material and forms an axial bidirectional limiting together with the locking block 10. The position of the limiting plate 13 can also be initially adjusted before picking up the material. When the adjusting screw 14 is rotated, the guide rod 12 moves accordingly. The position of the limiting plate 13 is determined by the reading of the scale ring 16.

[0028] Although this disclosure has been described with respect to only a limited number of embodiments, those skilled in the art who benefit from this disclosure will understand that various other embodiments can be devised without departing from the scope of this invention.
