Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery production, in particular to a chain belt threading mechanism. Background Art

[0002] Lithium-ion power batteries have high operating voltage (three times that of nickel-cadmium batteries and nickel-hydrogen batteries), large specific energy (up to 165WH / kg, three times that of nickel-hydrogen batteries), small size, light weight, long cycle life, low self-discharge rate, no memory effect, and no pollution, etc., so they are widely welcomed in the market.

[0003] In the production process of battery cells, the pole piece needs to pass through different rollers, and after adjustment and correction by various assemblies, it needs to be wound with the diaphragm in the winding assembly to make a qualified battery cell. The existing winding machine requires manual insertion of the pole piece into different mechanisms before production, so it needs to be pulled onto different rollers, which not only makes it easy to put the pole piece into the wrong position, and scratch the pole piece with different assemblies, but also wastes a lot of time and affects production efficiency. Utility Model Content

[0004] The main purpose of the utility model is to provide a chain threading mechanism to solve the above technical problems and improve the threading efficiency.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] As a preferred technical solution, the chain structure includes a chain, a first sprocket, a second sprocket and a third sprocket. The first sprocket is fixed to one end of the roller structure, the second sprocket is installed on one side of the ear smoothing support plate structure, and the third sprocket is arranged above the roller structure. The first sprocket, the second sprocket and the third sprocket are connected by the chain.

[0008] As a preferred technical solution, the chain structure also includes a hand-cranked sprocket assembly, and the hand-cranked sprocket assembly is installed on one side of the roller structure.

[0009] As a preferred technical solution, the hand-cranked sprocket assembly includes a handle and a hand-cranked sprocket, the handle is fixed to the hand-cranked sprocket, and the hand-cranked sprocket is connected to the chain.

[0010] As a preferred technical solution, the chain structure also includes a tensioning sprocket, and the tensioning sprocket is connected to the chain.

[0011] The beneficial effect of the utility model is that the above-mentioned chain threading mechanism first puts the threading rod into the two chain structures when threading, fixes the end of the pole piece on the threading rod with adhesive tape, and operates the hand-cranked sprocket assembly to make the chain drive drive the threading rod to move, thereby realizing threading, without the need for manual direct pulling of the material belt, avoiding damage to the pole piece, reducing the threading time, and improving production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 The utility model is a schematic structural diagram of a chain threading mechanism. DETAILED DESCRIPTION

[0013] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0014] like Figure 1 As shown, a chain belt threading mechanism includes a large plate 1, a roller structure 2, a pole lug smoothing support plate structure 3, a chain structure 4 and a belt threading rod (not shown in the figure), two large plates 1 are provided, and multiple roller structures 2 and pole lug smoothing support plate structures 3 are provided. The two ends of the roller structures 2 and the pole lug smoothing support plate structures 3 are respectively fixed on the two large plates 1, and the pole lug smoothing support plate structure 3 is installed between the two roller structures 2 for supporting the pole piece and the pole lug. Two chain structures 4 are also provided, and the chain structure 4 is installed on the large plate 1. The belt threading rod is inserted into the two chain structures 4. When threading, the chain structure 4 is first driven to drive the pole piece to pass through the roller structure 2 and the pole lug smoothing support plate structure 3, and then moved to the winding mechanism a for winding.

[0015] Specifically, the chain structure 4 includes a chain 44, a first sprocket 41, a second sprocket 42, a third sprocket 43, a hand-cranked sprocket assembly 45 and a tensioning sprocket 46. The first sprocket 41 is fixedly arranged at the end of the roller structure 2, and the pole piece passes through the roller structure 2 to realize the pole piece threading. The second sprocket 42 is installed on one side of the pole ear smoothing support plate structure 3. The third sprocket 43 is arranged around the roller structure 2 and is located above the roller structure 2, so that the chain 44 can be looped back to form a closed loop. The first sprocket 41, the second sprocket 42, the third sprocket 43, the hand-cranked sprocket assembly 45 and the tensioning sprocket 46 are connected by the chain 44. The hand-cranked sprocket assembly Component 45 is installed on one side of the roller structure 2. Rotating the hand-cranked sprocket assembly 45 can drive the chain 44 to transmit, thereby driving the pole piece to be threaded. The tensioning sprocket 46 can keep the chain 44 taut to prevent the chain 44 from loosening and disengaging during the transmission process, and at the same time prevent the chain 44 from sagging and colliding with the pole ear smoothing support plate structure 3. The hand-cranked sprocket assembly 45 includes a handle 451 and a hand-cranked sprocket 452. The handle 451 is fixed to the hand-cranked sprocket 452, and the hand-cranked sprocket 452 is connected to the chain 44. Operating the handle 451 can rotate the hand-cranked sprocket 452, thereby transmitting the chain 44 to drive the threading rod to move, thereby threading the pole piece.

[0016] The diameter of the strap-threading rod is larger than the distance between the pole lug-smoothing support plate structure 3 and the pole piece, so as to avoid bending and deformation of the strap-threading rod during use.

[0017] The above-described embodiments are only preferred examples of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made based on the structures, features and principles described in the patent application scope of the present invention should be included in the scope of the patent application of the present invention.
