Description

Technical Field

[0001] This utility model relates to lithium battery inkjet printing, specifically a lithium battery inkjet printing device. Background Technology

[0002] Lithium battery inkjet printing mainly refers to the process of marking on the surface of battery adhesive tape. Battery adhesive tape is a protective layer that is pasted on the outer ring of a cylindrical battery, and inkjet printing is usually carried out after the battery has been wrapped with adhesive tape.

[0003] For example, Chinese patent publication CN104553360B, published on June 22, 2016, discloses a lithium battery inkjet printing device, which includes a feeding device, a dispensing device, and a conveyor belt connected in sequence, and an inkjet printer located on one side of the conveyor belt. The feeding device includes: an upright lithium battery slot, an inclined guide plate, a gripping mechanism, and a baffle plate; the dispensing device includes: a lithium battery baffle plate, and the conveyor belt is supported below the feeding end of the bent section. The lithium battery inkjet printing device of this invention has a compact structure, a high degree of automation, and can quickly and effectively distribute boxed lithium batteries evenly onto the conveyor belt for inkjet printing, reducing labor costs and providing high inkjet printing accuracy, effectively improving production efficiency and lithium battery quality.

[0004] One limitation of this technology is that the coding is performed after the battery is fully manufactured. However, for some small-scale workshops, battery adhesive tape is usually wrapped manually around the cylindrical battery, and the tape itself is pre-cut by automated equipment. If the coding could be performed on the battery adhesive tape during the cutting stage, it would help simplify the production process and reduce the number of steps compared to coding after battery assembly.

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0029] Please see Figure 1-5 This utility model provides a technical solution: a lithium battery inkjet printing device for inkjet printing on battery adhesive tape 1. The device mainly includes a fully automatic online inkjet printer, a first support platform 2, a working plate 5, a second support platform 3, and a cutting assembly 4.

[0030] Specifically, the coding execution end 200 of the fully automatic online inkjet printer is fixedly installed on the bracket 21 on the side wall of the first support platform 2, with its working surface facing the first support platform 2, and is used to perform coding on the passing battery adhesive paper 1.

[0031] The working plate 5 is rotatably equipped with a support guide roller 51, a negative pressure guide roller 52, and a tape mounting plate 53. The support guide roller 51 and the negative pressure guide roller 52 are respectively rolled and connected to both sides of the battery adhesive tape 1 passing through; the tape is mounted on the tape mounting plate 53, the back of which is in rolling contact with the negative pressure guide roller 52, and the adhesive side is in contact with the coding side of the battery adhesive tape 1, so as to achieve coverage and protection of the coding area.

[0032] A hot air blower 10 is fixedly installed on the second support platform 3, with its hot air outlet facing the moving battery adhesive tape 1 on the platform surface. This is used to treat the tape with hot air after it is bonded, thereby enhancing its adhesion strength to the battery adhesive tape.

[0033] The cutting component 4 is located on the side of the second support platform 3 near the first support platform 2, and includes a single-blade cutting blade 41 that can move in the vertical direction, used to cut the battery adhesive paper 1 to a fixed length after the coding and coating are completed.

[0034] In this embodiment, the processing flow of the battery adhesive tape 1 is as follows: First, after the battery adhesive tape 1 enters the device, it is printed by the inkjet printing execution end 200; then, when passing between the support guide roller 51 and the negative pressure guide roller 52, the adhesive surface of the tape released by the tape mounting plate 53 adheres to the printing surface to form a cover; next, the battery adhesive tape 1 enters the second support platform 3, and the hot air blower 10 blows hot air on the tape area to enhance the adhesion effect; finally, the cutting component 4 cuts the battery adhesive tape 1 according to the preset length.

[0035] As a preferred embodiment of this utility model, combined with Figure 4As shown, the cutting assembly 4 includes a basic frame consisting of an upper crossbeam 42 and a lower crossbeam 43, connected by two symmetrically welded guide rollers 44. A moving part 45 is slidably mounted on these two guide rollers 44, and a single-blade cutting blade 41 is fixedly installed on this moving part 45. To ensure cutting accuracy and safety, the guide rollers 44 are provided with limiting parts 46 with blade holes, and the upper crossbeam 42 is provided with a corresponding blade receiving groove 421 to provide space for the upward movement of the cutting blade. In terms of drive, an electric push rod 47 installed on the lower crossbeam 43 has its output end fixedly connected to the moving part 45, which can precisely control its lifting and lowering. The cutting action is triggered by a sensing system: a Hall sensor (not shown in the figure) arranged on the second support platform 3 measures the length by sensing the number of times the roller rolls on the battery adhesive paper 1. When the preset value is reached, a signal is sent to start the electric push rod 47 to complete one cutting cycle.

[0036] As another embodiment, combined with Figure 4 As shown, a diagonal rod 70 is fixedly installed on the first support platform 2, and a rotating disk 71 is rotatably mounted at the end of the diagonal rod 70 for assembling the disc-shaped battery adhesive paper 1. The rotating disk 71 is fixed to the limiting plate 72 by bolts at the axis to ensure stability during the unwinding process.

[0037] Furthermore, combined Figure 2 As shown, the installation height of the supporting guide roller 51 and the negative pressure guide roller 52 is lower than the working surfaces of the first support platform 2 and the second support platform 3. Guide roller shafts 8 are respectively provided on their adjacent sides to guide the direction of the battery adhesive paper 1. A downward pressure guide roller 54 is also rotatably mounted on the working plate 5. The battery adhesive paper 1 is introduced downwards via the guide roller shaft 8 on the first support platform 2, passes between the supporting guide roller 51 and the negative pressure guide roller 52, continues downwards around the downward pressure guide roller 54, and then is guided upwards to the guide roller shaft 8 on the second support platform 3, forming a stable conveying path.

[0038] An H-shaped mounting bracket 31 is fixed on the second support platform 3, on which multiple spoon-shaped elastic elements 9 are installed in a linearly equidistant arrangement. The outer arc surface of the spoon-shaped elastic element 9 slides in contact with the adhesive tape on the surface of the battery adhesive paper 1, thereby achieving a pressing and positioning function.

[0039] Furthermore, combined Figure 1 As shown, a limit plate 6 is fixed to the second support platform 3 by bolts, and a predetermined gap is left between it and the platform surface. The battery adhesive tape 1 passes through this gap and enters the working area of ​​the hot air blower 10.

[0040] It should be noted that a limit plate 531 is fixed to the tape mounting plate 53 by bolts at the shaft center, which is used to axially limit the assembled tape roll and prevent it from shifting during operation.

[0041] As another embodiment, combined with Figure 5As shown, symmetrical transmission wheel sets 22 are arranged on the second support platform 3. Each set includes two guide rollers arranged vertically. The two guide rollers located on the same horizontal plane are connected to the output end of the drive motor inside the platform via a synchronous belt. The battery adhesive paper 1 passes through the transmission wheel sets 22, and the air outlet of the hot air blower 10 is located between the two sets of transmission wheels. The transmission wheel sets 22 are not only used to transport the battery adhesive paper 1, but also to flatten and position it, ensuring uniform hot air treatment and accurate cutting position.

[0042] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
