Description

Technical Field

[0001] The utility model belongs to the field of isostatic graphite processing, in particular to an isostatic graphite carbon rod marking device. Background Art

[0002] Isostatically pressed graphite boasts high strength, density, purity, and a dense and uniform structure, making it widely used in fields such as semiconductors, solar energy, electrical discharge machining (EDM), and nuclear energy. Many products require surface marking after they come off the production line. However, marking graphite carbon rods requires a different approach from other industries. Common side- or top-marking methods, such as side-marking, can easily knock over the product and produce poor marking results on cylindrical sides. Currently, most operations rely on manual marking, resulting in inconsistent marking positions and labor-intensive processes.

[0003] In the prior art, there are also fiber laser marking machines used to mark carbon rods and other graphite carbon rods. However, there is a problem that when the carbon rod and other graphite carbon rods are moved to the marking head position for marking, movement will occur, resulting in unclear marking and reduced marking quality. CN219115129U discloses a carbon rod fiber laser marking machine, in which the carbon rod enters from the blanking plate to the top of the feeding plate, and the carbon rod is manually pushed. The carbon rod moves to the position of the operating frame, and the carbon rod enters between the two inclined plates. The two inclined plates guide the carbon rod to enter between the two limit plates for limited placement. At this time, the moving component drives the marking head to move and perform marking operations on the surface of the carbon rod. However, this marking operation still requires manual pushing of the carbon rod, and graphite powder affects the human body. Moreover, the limit plate is used for limiting. For cylindrical carbon rod products, there is still a problem that movement will occur during marking, resulting in unclear marking. Utility Model Content

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies and defects mentioned in the above background technology and provide an isostatic graphite carbon rod marking device that can realize full-automatic marking with clear marking effect and good result stability.

[0005] In order to solve the above technical problems, the technical solutions proposed by the present invention are as follows:

[0006] An isostatically pressed graphite carbon rod marking device, comprising:

[0007] base,

[0008] a conveyor belt mounted on a base;

[0009] The clamping device includes a pair of clamping jaws and a guide column connected to the clamping jaws. The pair of clamping jaws are located on both sides of the conveyor belt and are used to clamp the graphite carbon rods that need to be coded.

[0010] A pair of telescopic cylinders, each connected to a clamping jaw, controls the clamping jaw's telescopic movement to clamp or release the graphite carbon rod;

[0011] The fiber laser marking machine is fixed on the base and includes a marking head and a photoelectric sensor. The marking head is located above the conveyor belt. When the photoelectric sensor senses the material, the conveyor belt stops conveying and the clamp clamps the graphite carbon rod. After the fiber laser marking machine marks the graphite carbon rod, the conveyor belt conveys the graphite carbon rod.

[0012] In one embodiment, baffles are provided on both sides of the conveyor belt.

[0013] In one embodiment, the baffle is in an eight-shaped shape at the inlet section of the conveyor belt, and the baffle is arranged in parallel at the conveying section of the conveyor belt.

[0014] In one embodiment, the clamping head of the clamping jaw is arc-shaped or V-shaped.

[0015] In one embodiment, the fiber laser marking machine includes a support base, which includes a column fixed on a base and a bottom plate located on the column, wherein a telescopic cylinder is located below the bottom plate.

[0016] In one embodiment, the fiber laser marking machine includes a linear module fixed on a base plate, and the marking head can move up and down along the linear module.

[0017] In one embodiment, the surface of the clamping jaws for clamping the graphite carbon rod is provided with sponge.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: the isostatically pressed graphite carbon rod marking device of the present application utilizes a conveyor belt to transport the graphite carbon rod. At the same time, when the graphite carbon rod is transported to the bottom of the marking head of the fiber laser marking machine, the conveyor belt stops conveying, and the graphite carbon rod is clamped by a clamp, and then the fiber laser marking machine is used to mark the graphite carbon rod, completing the marking operation. The entire marking process adopts a mechanized operation, which solves the adverse effects of working in an artificial graphite dust environment. The graphite carbon rod is fixed by the clamp before marking, and no movement occurs during marking, so the marking is clear and the position is uniform, which facilitates the subsequent code recognition operation.

[0024] See also Figure 1 , an isostatically pressed graphite carbon rod marking device, comprising: a base 10, a clamping device, a telescopic cylinder 30 and a fiber laser marking machine 40. A conveyor belt 12 is installed on the base 10 for conveying the graphite carbon rod 1. The clamping device comprises a pair of jaws 22 and a guide column 24 connected to the jaws, and the guide column 24 is used to position the clamp 22. Each jaw 22 is connected to two guide columns 24. A pair of jaws 22 are respectively located on both sides of the conveyor belt 12 and are symmetrically arranged, and are used to clamp the graphite carbon rod 1 that needs to be coded. A pair of telescopic cylinders 30, each telescopic cylinder 30 is connected to a jaw 22, controls the telescopic movement of the jaw 22 to clamp or release the graphite carbon rod 1. The fiber laser marking machine 40 is fixed on the base 10 and includes a marking head 42 and a photoelectric sensor. The marking head 42 is located above the conveyor belt 12. When the photoelectric sensor senses the graphite carbon rod, the conveyor belt 12 stops conveying and the clamp 22 clamps the graphite carbon rod. After the fiber laser marking machine 40 marks the graphite carbon rod, the conveyor belt 12 conveys the graphite carbon rod out.

[0025] In one embodiment, baffles 14 are provided on both sides of the conveyor belt 12 to limit the position of the graphite carbon rods and prevent them from rolling off. Preferably, the baffles 14 are shaped like a figure eight at the conveyor belt entrance and are arranged parallel to the conveyor belt conveyor section. This arrangement of baffles 14 facilitates the placement of the graphite carbon rods, as the figure eight structure can guide graphite carbon rods 1 that are not in the middle position.

[0026] In one embodiment, the clamping head of the clamping jaw 22 is arc-shaped or V-shaped, which can more firmly clamp the graphite carbon rod.

[0027] In one embodiment, the fiber laser marking machine 40 includes a support base, which includes a column 440 fixed to the base 10 and a bottom plate 442 located on the column 440. A telescopic cylinder 30 is located below the bottom plate 442 and between the columns 440. The positioning of the support base and the telescopic cylinder 30 can better control the position of the marking head 42 and more accurately align it with the graphite carbon rod to be marked.

[0028] In one embodiment, the fiber laser marking machine 40 includes a linear module 444 fixed to a base plate 442, along which a marking head 42 can move up and down. For graphite carbon rods of different lengths, the distance between the marking head 42 and the graphite carbon rod can be adjusted by moving the marking head 42.

[0029] In one embodiment, the surface of the clamping jaws 22 for clamping the graphite carbon rod is provided with sponge to prevent the clamping jaws 22 from scratching the graphite carbon rod.

[0030] The isostatically pressed graphite carbon rod marking device of the present application utilizes a conveyor belt 12 to convey the graphite carbon rod. Simultaneously, when the graphite carbon rod 1 is conveyed to the position directly below the marking head 42 of the fiber laser marking machine 40, the conveyor belt 12 stops conveying, and after the graphite carbon rod 1 is clamped by the clamp 22, the fiber laser marking machine 10 is used to mark the graphite carbon rod 1, completing the marking operation of the graphite carbon rod 1. The entire marking process is mechanized, which solves the adverse effects of working in an artificial graphite dust environment. Furthermore, the graphite carbon rod 1 is fixed by the clamp 22 for marking, and no movement occurs during marking, achieving clear marking and uniform positioning, facilitating subsequent code recognition operations.
