Description

Technical Field

[0001] This utility model relates to the field of lithium battery cell marking technology, and in particular to a marking device for lithium battery cells. Background Technology

[0002] A battery cell is the core component of a lithium battery. It refers to a single electrochemical cell containing positive and negative electrodes and is generally not used directly. A battery cell mainly consists of positive electrode material, negative electrode material, electrolyte, separator, and casing. A lithium battery, on the other hand, is a complete battery unit composed of a battery cell plus a protective circuit board and casing, and can be used directly. After the battery cells are tested, problematic cells are marked and centrally processed.

[0003] However, marking lithium battery cells usually requires both hands, i.e., one hand holds the raw material and the other hand marks it, which is very inconvenient. Moreover, the marking is usually done with stickers or ink pads, which are not firm and are easily scratched and damaged. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a marking device for lithium battery cells. When marking lithium battery cells, it is usually necessary to use both hands, that is, one hand holds the raw material and the other hand marks it, which is very inconvenient. Moreover, when marking, stickers or ink pads are usually used, which are not firm and are easily scratched and damaged.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is a marking device for lithium battery cells, including a handle and a switch. The switch is installed on the front wall of the handle, a material cylinder support ring is connected to the upper end of the handle, a material dispensing structure is installed inside the material cylinder support ring, a marking structure is installed on the inner wall of the material dispensing structure, and a shaping structure is connected to the front wall of the handle.

[0006] As a further embodiment of this utility model: the feeding structure includes: a material cylinder, a first sealing cover, a rotating handle, and a second sealing cover; the material cylinder is installed on the inner wall of the material cylinder support ring, the first sealing cover is installed on the rear end face of the material cylinder and is threadedly connected to the material cylinder, the rotating handle is installed on the rear wall of the first sealing cover, and the second sealing cover is fitted onto the front end face of the material cylinder and is threadedly connected to the material cylinder.

[0007] As a further embodiment of this utility model: the marking structure includes: a ball valve, a flow guide rod, a spring positioning sleeve, a stamp fixing frame, and a marking stamp; the ball valve is installed on the inner wall of the material cylinder, the flow guide rod is installed on the front end face of the ball valve, the spring positioning sleeve is installed on the front end face of the material cylinder, the stamp fixing frame is installed on the front end face of the flow guide rod, and the marking stamp is installed on the inner wall of the stamp fixing frame.

[0008] As a further embodiment of this utility model: the shaping structure includes: a shaping fixing frame, a shaping connecting sleeve, and an ultraviolet irradiation lamp; the shaping fixing frame is installed on the front wall of the handle, the shaping connecting sleeve is connected to the outer wall of the shaping fixing frame, and the ultraviolet irradiation lamp is installed on the shaping connecting sleeve.

[0009] As a further embodiment of this utility model: a battery compartment is installed inside the handle.

[0010] As a further aspect of this utility model: the material cylinder is filled with UV dye adhesive.

[0011] As a further embodiment of this utility model, a return spring is fitted onto the outer wall surface of the drainage rod.

[0012] The present invention adopts the above technical solution and has the following advantages compared with the prior art:

[0013] The ball valve is automatically reset by a return spring, ensuring that the UV dye adhesive in the barrel is not wasted. The amount of adhesive dispensed is constantly controlled as the marking stamp is pressed, achieving adjustable marking concentration and preventing unclear marking. At the same time, it enables one-handed operation, solving the problem that lithium battery cells usually require two hands to mark, i.e., one hand to hold the raw material and the other hand to mark, which is very inconvenient.

[0014] Because ultraviolet light has high energy and can rapidly trigger chemical reactions, the curing process is very fast. Therefore, UV adhesive can cure almost instantly in a short time, forming a strong bond or coating. The operator points the ultraviolet lamp at the mark, pulls the switch to turn on the ultraviolet lamp, and the UV dye adhesive is cured instantly, ensuring that the mark is not easily scratched or damaged. This solves the problem that when marking is usually done with stickers or ink pads, the marks are not firm and are easily scratched and damaged. Attached Figure Description

Detailed Implementation

[0020] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0021] Example 1, please refer to Figures 1-4 A marking device for lithium battery cells includes a handle 1 and a switch 2. The switch 2 is mounted on the front wall of the handle 1. A material cylinder support ring 3 is connected to the upper end of the handle 1. A material feeding structure is installed inside the material cylinder support ring 3. A marking structure is installed on the inner wall of the material feeding structure. A shaping structure is connected to the front wall of the handle 1.

[0022] Please see Figures 1-3 The material feeding structure includes: a material cylinder 4, a first sealing cover 5, a rotating handle 6, and a second sealing cover 7; the material cylinder 4 is installed on the inner wall of the material cylinder support ring 3, the first sealing cover 5 is installed on the rear end face of the material cylinder 4 and is threadedly connected to the material cylinder 4, the rotating handle 6 is installed on the rear wall of the first sealing cover 5, and the second sealing cover 7 is fitted on the front end face of the material cylinder 4 and is threadedly connected to the material cylinder 4.

[0023] Please see Figures 3-4 The marking structure includes: a ball valve 8, a flow guide rod 9, a spring positioning sleeve 10, a stamp fixing frame 11, and a marking stamp 12; the ball valve 8 is installed on the inner wall of the material cylinder 4, the flow guide rod 9 is installed on the front end of the ball valve 8, the spring positioning sleeve 10 is installed on the front end of the material cylinder 4, the stamp fixing frame 11 is installed on the front end of the flow guide rod 9, and the marking stamp 12 is installed on the inner wall of the stamp fixing frame 11.

[0024] In this embodiment, the ball valve 8 is automatically reset by the reset spring 16, ensuring that the UV dye glue in the barrel 4 is not wasted. The glue output is constantly controlled when the marking stamp 12 is pressed, so as to realize the function of adjustable marking concentration and prevent unclear marking.

[0025] The barrel 4 contains UV dye adhesive. In this embodiment, the product cured with UV adhesive has good weather resistance and can resist the influence of environmental factors such as ultraviolet rays, moisture, and high temperature, maintaining long-term stability and making the marking not easily damaged.

[0026] Please see Figure 3 A return spring 16 is fitted on the outer wall of the drain rod 9. In this embodiment, the ball valve 8 is automatically reset by the return spring 16.

[0027] Specifically, the operator holds handle 1, unscrews the second sealing cap 7, places the marking stamp 12 downwards, and rotates the rotating handle 6 clockwise. The rotating handle 6 causes the first sealing cap 5 to rotate in the material cylinder 4. After rotating to a certain extent, a gap is created between the material cylinder 4 and the first sealing cap 5, ensuring that the UV dye adhesive in the material cylinder 4 can be discharged smoothly. Then, the operator aligns the marking stamp 12 with the top of the lithium battery cell to be marked, keeps the material cylinder 4 vertically downwards, and presses the marking stamp 12. The marking stamp 12 is driven by the guide rod 9, and the ball valve 8 is pushed into the material cylinder 4. The return spring 16 contracts, and at this time, a gap is created between the ball valve 8 and the material cylinder 4. The UV dye adhesive enters the marking stamp 12 along the guide rod 9 through the guide groove opened on the stamp fixing frame 11. The marking stamp 12 marks the lithium battery cell. Then, the operator lifts handle 1, the marking stamp 12 is removed from the lithium battery cell, the return spring 16 expands, and drives the ball valve 8 to reset, blocking the material cylinder 4.

[0028] Example 2, please refer to Figure 1 The shaping structure includes: a shaping fixing frame 13, a shaping connecting sleeve 14, and an ultraviolet irradiation lamp 15; the shaping fixing frame 13 is installed on the front wall of the handle 1, the shaping connecting sleeve 14 is connected to the outer wall of the shaping fixing frame 13, and the ultraviolet irradiation lamp 15 is installed on the shaping connecting sleeve 14.

[0029] A battery compartment is installed inside the handle 1. In this embodiment, the ultraviolet lamp 15 is powered by the battery in the battery compartment.

[0030] In this embodiment, because ultraviolet light has high energy and can quickly trigger a chemical reaction, the curing process is very fast. Therefore, UV adhesive can cure almost instantly in a short time to form a strong bond or coating, ensuring that the markings are not easily scratched or damaged.

[0031] Specifically, after the marking stamp 12 marks the lithium battery cell, the operator aims the ultraviolet irradiation lamp 15 at the mark, pulls the switch 2 to turn on the ultraviolet irradiation lamp 15, and instantly cures the UV dye adhesive to ensure that the mark is not easily scratched or damaged.

[0032] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
