Description

Technical Field

[0001] This invention relates to the field of medical carbon rod processing technology, and specifically to a production process for medical carbon rods. Background Technology

[0002] The manufacturing process of medical carbon rods is quite complex, and the precision of each step directly affects the performance of the final product. These carbon rods use high-purity carbon as the main base material, while also doping with trace amounts of metallic elements such as cerium, lithium, strontium, magnesium, calcium, nickel, and titanium to optimize their conductivity, arc stability, and thermal radiation characteristics.

[0003] In certain treatment devices, two medical carbon rods are used as electrodes. When energized, the carbon in the gap between the electrodes is heated and vaporized, forming conductive plasma, which excites an electric arc discharge, generating ultra-high temperatures of up to about 3000°C and radiating a strong continuous spectrum of light. This physical process constitutes the technical basis of "carbon light therapy" and can be used in certain skin disease or physiotherapy devices.

[0004] Unlike traditional carbon rods, medical carbon rods are often designed with a hollow structure, and their core function depends on the active material (such as conductive paste, drug release carrier, or bioactive factor) filled in the central channel. Therefore, the "core-filling" process becomes a crucial step in determining product performance. To ensure uniform filling and accurate positioning, the hollow carbon rod must be precisely aligned and reliably fixed before filling. However, in existing technologies, this alignment and clamping process largely relies on manual operation, resulting in low positioning accuracy, poor consistency, and low work efficiency. Summary of the Invention

[0005] (1) Technical problems to be solved The purpose of this invention is to overcome the shortcomings of the prior art, adapt to practical needs, and provide a medical carbon rod production process that eliminates the need for manual operation in the hollow carbon rod alignment and clamping process during the core filling step, thereby solving the above-mentioned technical problems.

[0006] (2) Technical solution To achieve the objectives of this invention, the technical solution adopted is as follows: a production process for medical carbon rods, comprising the following steps: a. Preparation of hollow carbon rods; b. Preparation of the core material; c. Fill the hollow carbon rod with the core filling equipment; d. Heat and cure the filled rod. e. Cut the cured rod into the specified length, and then process one end into a tapered bevel. The filling device in step c includes a base, a filling assembly is provided on one side of the base, a motor is fixedly provided on the base, a rotating ring is rotatably provided on the base, a transmission assembly for driving the rotating ring to rotate is provided between the motor and the rotating ring, and multiple placement discs are evenly distributed along the circumferential direction on the rotating ring, and a positioning assembly is provided on each placement disc.

[0007] The transmission assembly includes a gear rotatably mounted on a base, the output end of the motor rotatably passes through the base and is fixedly connected to the gear, and the rotating ring has a plurality of meshing teeth evenly distributed along the circumferential direction for meshing with the gear.

[0008] The positioning component includes a positioning groove on the placement plate, two symmetrically distributed first positioning components arranged along the width direction of the positioning groove, two symmetrically distributed second positioning components arranged along the length direction of the positioning groove, and a linkage component that cooperates with the first and second positioning components.

[0009] The first positioning component includes a first push plate that is reciprocally movable on one side of the positioning groove, and the bottom end of the first push plate is on the same horizontal plane as the bottom end of the hollow carbon rod placed on the placement plate.

[0010] The second positioning component includes a second push plate that is reciprocally movable on one side of the positioning groove. An extension plate is fixedly provided at the lower end of the second push plate. The extension plate is located in the positioning groove. Two limiting inclined blocks are fixedly provided on one side of the extension plate, and the two limiting inclined blocks are symmetrically arranged.

[0011] The linkage component includes an external gear ring rotatably mounted on a placement plate, a mounting plate fixedly mounted on the base, an arc-shaped rack that mates with the external gear ring fixedly mounted on the mounting plate, two protrusions evenly distributed along the circumferential direction on the inner circumferential wall of the external gear ring, a first mating wedge fixedly mounted on the opposite side of the two first push blocks for mates with the protrusions, and a second mating wedge fixedly mounted on the opposite side of the two second push blocks for mates with the protrusions.

[0012] The first mating inclined block has a first inclined surface and a second inclined surface, and the second mating inclined block has a third inclined surface and a fourth inclined surface.

[0013] The top surface of the placement tray has four fixing plates evenly distributed along the circumference. Two fixing plates are located on one side of the first push plate, and the other two fixing plates are located on one side of the second push plate. Each fixing plate is provided with a limiting hole. Each first push plate is fixedly provided with a first limiting rod, which can reciprocate within the limiting hole. A first reset spring is fixedly provided between the fixing plate located on one side of the first push plate and the first push plate. Each second push plate is fixedly provided with a second limiting rod, which can reciprocate within the limiting hole. A second reset spring is fixedly provided between the fixing plate located on one side of the second push plate and the second push plate.

[0014] The filling assembly includes a cylinder, and a liquid pump is fixedly mounted on the piston rod of the cylinder. A thin tube is connected to the outlet end of the liquid pump, and the inlet end of the liquid pump is connected to the tank containing the filling core through a pipe.

[0015] The width of the positioning groove is 2-3 mm larger than the diameter of the hollow carbon rod to be processed.

[0016] Beneficial effects: With the setup of the first positioning component, the second positioning component, and the linkage component, when filling hollow carbon rods, the operator only needs to place the hollow carbon rod into the space enclosed by the four push plates on the placement plate. The hollow carbon rod can be automatically and accurately centered and reliably fixed before filling. This centering and clamping process does not rely on manual operation, thereby improving work efficiency. Attached Figure Description

Detailed Implementation

[0018] The following is in conjunction with the appendix Figure 1-12 The present invention is further illustrated by the embodiments: A manufacturing process for medical carbon rods includes the following steps: Preparation of hollow carbon rods; The specific steps for preparing hollow carbon rods are as follows: 150 parts of carbon black and 30-40 parts of asphalt are heated until softened and then pressed into blocks. The blocks are placed in a baking jar and heated to 550-600℃ for 1-3 days, then to 900-1000℃ for 2-4 days. The mixture is then cooled in the air. 20-35 parts of graphite are then added and ground together into 200-250 mesh powder. The powder is mixed with 50-60 parts of liquid asphalt to form a soft gel. The gel is then molded into hollow rod blanks using a mold and placed back into the baking jar for baking (550-600℃ → 900-1000℃). The rods are then cooled in the air-isolated environment to obtain hollow carbon rods. The hollow carbon rods are characterized by one end being open and the other end being closed.

[0019] Core preparation; The specific steps for preparing the core are as follows: mixing metal oxides, fluorosilicates, iron salts, potassium salts, rare earth metals, and metal fluorides, crushing and grinding them into 100-400 mesh micro powder (core material), adding an appropriate amount of resin, stirring evenly, and making a fillable gel.

[0020] c. Fill the hollow carbon rod with the core filling equipment; d. Heat and cure the filled rod. e. Cut the cured rod into the specified length, and then process one end into a tapered bevel. The filling device in step c includes a base 1, a filling assembly is provided on one side of the base 1, a motor 2 is fixedly mounted on the base 1, a rotating ring 3 is rotatably mounted on the base 1, a first annular groove 600 is provided on the base 1, a first positioning ring 601 that can rotate within the first annular groove 600 is fixedly mounted on the rotating ring 3, a transmission assembly for driving the rotating ring 3 to rotate is provided between the motor 2 and the rotating ring 3, and a plurality of placement discs 4 are evenly distributed along the circumferential direction on the rotating ring 3, and a positioning assembly is provided on each placement disc 4.

[0021] The transmission assembly includes a gear 30 rotatably mounted on the base 1. The output end of the motor 2 rotatably passes through the base 1 and is fixedly connected to the gear 30. The rotating ring 3 has a plurality of meshing teeth 31 evenly distributed along the circumferential direction for meshing with the gear 31. A protective shell 400 is fixedly mounted on the base 1. The gear 30 and the meshing teeth 31 are both located inside the protective shell 400, and the rotating ring 3 is located outside the protective shell 400.

[0022] The positioning component includes a positioning groove 40 disposed on the placement plate 4, two symmetrically distributed first positioning components disposed along the width direction of the positioning groove 40, two symmetrically distributed second positioning components disposed along the length direction of the positioning groove 40, and a linkage component that cooperates with the first and second positioning components.

[0023] The first positioning component includes a first push plate 50 that is reciprocally movable on one side of the positioning groove 40. The bottom end of the first push plate is on the same horizontal plane as the bottom end of the hollow carbon rod placed on the placement plate 4. With this arrangement, when the hollow carbon rod is pushed towards the positioning groove 40, the first push plate can be pushed from the bottom end of the hollow carbon rod, which makes it less likely for the hollow carbon rod to break than if it is pushed from the middle.

[0024] The second positioning component includes a second push plate 51 that is reciprocally movable on one side of the positioning groove 40. An extension plate 52 is fixedly provided at the lower end of the second push plate 51. The extension plate 52 is located in the positioning groove 40. Two limiting inclined blocks 53 are fixedly provided on one side of the extension plate 52, and the two limiting inclined blocks 53 are symmetrically arranged and located in the positioning groove 40.

[0025] By setting the extension plate, when the second push plate 51 moves closer to push the hollow carbon rod, the extension plate can push the bottom end of the hollow carbon rod that has fallen into the positioning groove. Compared with pushing from the middle of the hollow carbon rod to clamp it, pushing from the bottom end of the hollow carbon rod is less likely to cause the hollow carbon rod to break, thereby reducing the defect rate of the equipment. The hollow carbon rod is more accurately positioned and fixed by two limiting inclined blocks 53 and the second push plate 51, so that when the cylinder 501 moves down with the liquid pump 502 and the thin tube 503 to the upper end of the hollow carbon rod for core filling, the thin tube 503 can be inserted into the hollow carbon rod more smoothly for core filling.

[0026] The linkage component includes an outer gear ring 60 rotatably mounted on a placement plate 4, a second annular groove 650 on the placement plate 4, a second positioning ring 651 fixedly mounted on the outer gear ring 60 that can rotate within the second annular groove 650, a mounting plate 61 fixedly mounted on the base 1, an arc-shaped rack 62 fixedly mounted on the mounting plate 61 that mates with the outer gear ring 60, two protrusions 63 evenly distributed along the circumferential direction on the inner peripheral wall of the outer gear ring 60, a first mating wedge 64 fixedly mounted on the opposite side of the two first push blocks 50 for mating with the protrusions 63, and a second mating wedge 65 fixedly mounted on the opposite side of the two second push blocks 51 for mating with the protrusions 63; a cover 401 fixedly mounted on the placement plate 4, the cover 401 covering three-quarters of the area of ​​the outer gear ring 60.

[0027] The first mating wedge 64 has a first inclined surface 641 and a second inclined surface 642, and the second mating wedge 65 has a third inclined surface 651 and a fourth inclined surface 652. The presence of these four inclined surfaces allows the first and second push plates to move and to reduce their moving and resetting speeds when the protrusion pushes the first and second mating wedges, and when the protrusion moves away from their center. This makes it less likely that the hollow carbon rod will be damaged when the first and second push plates push it to move or release it for resetting.

[0028] The top surface of the placement tray 4 is evenly distributed with four fixing plates 70 along the circumferential direction. Two fixing plates 70 are located on one side of the first push plate 50, and the other two fixing plates 70 are located on one side of the second push plate 51. Each fixing plate 70 is provided with a limiting hole. Each first push plate 50 is fixedly provided with a first limiting rod 71, which can reciprocate within the limiting hole. A first reset spring 72 is fixedly provided between the fixing plate 70 located on one side of the first push plate 50 and the first push plate 50. Each second push plate 51 is fixedly provided with a second limiting rod 73, which can reciprocate within the limiting hole. A second reset spring 74 is fixedly provided between the fixing plate 70 located on one side of the second push plate 51 and the second push plate 51.

[0029] The filling assembly includes a vertical rod 500 disposed on one side of the base 1, a cylinder 501 fixedly disposed on the vertical rod 500, a liquid pump 502 fixedly disposed on the piston rod of the cylinder 501, a thin tube 503 connected to the outlet end of the liquid pump 502, and the inlet end of the liquid pump 502 connected to the can containing the filling core through a pipe 504.

[0030] The width of the positioning groove 40 is 2-3 mm larger than the diameter of the hollow carbon rod to be processed; this setting allows the hollow carbon rod to fall into the positioning groove 40 more smoothly when it comes to the top of the positioning groove 40.

[0031] In this embodiment, the length of the hollow carbon rod is the same as the height of the first push plate 50 and the second push plate 51 set on the placement tray 4. This allows the operator to vertically place the hollow carbon rod into the space enclosed by the four push plates. After the operator releases the hollow carbon rod, the upper end of the hollow carbon rod will tilt and abut against the first or second push plate. Therefore, through the coordinated action of the four push plates, the tilted hollow carbon rod can be pushed straight more smoothly.

[0032] The working principle of this invention includes the following process: The operator first places the hollow carbon rod with the through-hole end facing upwards and vertically between the two first push plates 50 and the two second push plates 51 (the hollow carbon rod is positioned so that one end rests against the side of the first push plate 50, the side of the second push plate 51, or between the angles between the first push plate 50 and the second push plate 51). Then, the motor 2 is started, causing the gear 30 to rotate. The gear 30 drives the meshing teeth 31 to rotate. When the meshing teeth 31 rotate counterclockwise with the rotating ring 3, causing the placement disk 4 on the rotating ring 3 to approach the arc-shaped rack 62, the outer gear ring 60 will mesh with the arc-shaped rack 62. Then, the outer gear ring 60 will rotate on its own... When the external gear ring 60 rotates, it will cause the protrusion 63 to rotate as well. After the external gear ring 60 rotates 45°, the protrusion 63 will first abut against the first mating inclined block 64, thereby pushing the first mating inclined block 64 to move. This allows the two first mating inclined blocks 64 to bring the first push block 50 closer together. When the first push block 50 comes together, it will push the hollow carbon rod located therein to the top of the positioning groove 40 (at this time, the protrusion 63 just abuts against the intersection of the two inclined surfaces on the first mating inclined block 64, that is, the protrusion 63 abuts against the middle of the first mating inclined block 64). Then, as the protrusion 63 rotates until it no longer abuts against the first mating inclined block 64, the first push plate 50 will be reset by the first reset spring 72. Returning to the initial position, the hollow carbon rod falls into the positioning groove 40, thus initially limiting its position in the width direction of the positioning groove 40 (at this time, the hollow carbon rod is tilted against the groove wall of the positioning groove 40 or the side of the second push plate 51). As the protrusion 63 continues to rotate 90°, when the protrusion 63 abuts against the second mating wedge 65, the two second mating wedges 65 bring the second push blocks 51 closer together. When the second push blocks 51 bring the extension plate 52 closer together, they limit the hollow carbon rod located in the positioning groove 40 along the length direction of the positioning groove 40. Furthermore, the setting of the two limiting wedges 53 allows the hollow carbon rod to be initially limited by the two second push blocks 51. When fully clamped, it can also be further accurately limited along the width direction of the positioning groove 40. When the intersection of the two inclined surfaces on the protrusion 63 and the second mating inclined block 65 is abutted (that is, the protrusion abuts the middle of the second mating inclined block 65), the thin tube 503 is just above the hollow carbon rod. Therefore, when it reaches the position directly above the hollow carbon rod, the two limiting inclined blocks 53 and the second push plate 51 can more accurately position and fix the hollow carbon rod. Thus, when the cylinder 501 moves down with the liquid pump 502 and the thin tube 503 to the upper end of the hollow carbon rod for core filling, the thin tube 503 can be inserted into the hollow carbon rod more smoothly for core filling. After the core filling is completed, the rotating ring 3 rotates again when the motor 2 is restarted. As the arc-shaped rack 62 meshes with the outer gear ring 60, the outer gear ring 60 continues to rotate 45°. Therefore, when the outer gear ring 60 moves to a position where it no longer meshes with the arc-shaped rack 62, the protrusion 63 also stops pressing against the second mating inclined block 65. Under the reset action of the second reset spring 74, the second push plate 51 no longer clamps the rod after the core filling, making it easier for the operator to directly remove the rod after the core filling, thus improving work efficiency.

Those skilled in the art can readily grasp the spirit of the present invention based on the above embodiments and make different extensions and variations, but as long as they do not depart from the spirit of the present invention, they are all within the protection scope of the present invention.
