Description

Technical Field

[0001] This invention relates to the technical field of graphite boat carving and grooving equipment, specifically to a graphite boat processing center. Background Technology

[0002] The processing of graphite boat sheets first requires cutting graphite blocks into graphite slices, then carving grooves into the surface of the slices, and finally manually installing graphite shims into the shim holes of the slices. In existing graphite engraving machines, the graphite boat sheets are fixed in place using a clamping device to maintain their position and allow for engraving and grooving. However, vibrations are inevitably generated during grooving. When these vibrations resonate severely with the vibrations at the clamping point, they can damage the graphite boat sheets, resulting in a decrease in the number of qualified graphite boat sheets. Therefore, we aim to improve the yield of qualified graphite boat sheets while maintaining the required grooving accuracy. We design a processing device that protects the graphite boat sheets from resonance damage during processing, thus ensuring product quality. Summary of the Invention

The receiving portion is provided with a dust-guiding groove corresponding to the support platform. The dust-guiding groove is connected to the negative pressure chamber. The height of the dust-guiding groove increases as it extends outward.

[0009] Preferably, the top of the ash-guiding channel is provided with an adjustable angle adjustment device, which includes a rotating plate, a vertical rod axially connected to one end of the rotating plate, and a plate. The other end of the rotating plate is axially connected to the top side wall of the ash-guiding channel. The vertical rod is fixed to both ends of the upper surface of the plate.

[0010] Preferably, the extension line of the rotating plate intersects the center line of the graphite boat sheet to be engraved and slotted.

[0011] Preferably, the receiving part is provided with a dust removal hole between the support platform and the dust inlet channel, the dust removal hole is connected to the dust removal channel, and the dust removal channel is higher than the negative pressure chamber.

[0012] Preferably, the first motor is mounted on the frame and connected to the first rotating screw via a belt.

[0013] In summary, the present invention has the following beneficial effects.

[0014] 1. The external pipe of the negative pressure port is connected to a high-pressure blower. The high-pressure blower draws air outward. When no graphite boat is loaded, air is drawn in from the microporous support plate and drawn out from the negative pressure chamber through the negative pressure hole. When a graphite boat is loaded, air is drawn in from the microporous support plate and drawn out from the negative pressure chamber through the negative pressure hole. After the air is drawn out, the graphite boat is firmly attached to the microporous support plate and cannot move, ensuring that the graphite boat remains in position and does not shift during subsequent carving and grooving.

[0015] 2. By connecting a high-pressure blower to the negative pressure base, negative pressure is applied to the graphite boat sheet. The negative pressure attraction stably adsorbs the graphite boat sheet, keeping its position from shifting. At the same time, the negative pressure attraction absorbs the vibrations generated during engraving, protecting the graphite boat sheet.

[0016] 3. Two symmetrically arranged reinforcing inclined surfaces draw air outwards via a high-pressure blower. The air between the two adjacent support platforms is removed. Due to the presence of the reinforcing inclined surfaces, a fan-shaped negative pressure attraction zone is formed. This fan-shaped negative pressure attraction zone strengthens the attraction force on the graphite boat portion located between the two support platforms, further enhancing the fixing effect on the graphite boat. This prevents the graphite boat from shifting during carving and grooving, thus preventing errors caused by the displacement of the graphite boat and improving the accuracy of carving and grooving.

[0017] 4. By setting up a dust-guiding groove with an inclined top surface, the dust particles generated after carving and grooving can be attracted and guided by the negative pressure airflow of the dust-guiding groove, so that the dust leaves the graphite boat sheet while carving and grooving. This ensures that the graphite boat sheet is not affected by the dust particles generated during carving and grooving, thus affecting the accuracy of the next grooving step and ensuring the quality of grooving.

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0028] Example 1

[0029] like Figures 1 to 7 As shown, a graphite boat sheet processing center includes a frame 1, a worktable 2, an engraving device 3 for engraving and grooving graphite boat sheets, and a power system 4 for controlling the movement of the engraving device 3. The worktable 2 includes a porous negative pressure base 5 and a microporous support plate 6. The upper surface of the porous negative pressure base 5 is recessed downward to form a receiving portion 7. The microporous support plate 6 is connected to the receiving portion 7. A negative pressure chamber 8 is provided below the receiving portion 7. The receiving portion 7 has a negative pressure hole 20 communicating with the negative pressure chamber 8. A negative pressure port 10 communicating with the negative pressure chamber 8 is opened on the side wall of the porous negative pressure base 5. The negative pressure port 10 is connected to an external pipe 11, which is connected to a high-pressure blower 12. As shown... Figure 1The high-pressure blower 12 shown is indicated by a dashed line and can be installed in the frame 1. The high-pressure blower 12 is chosen in this application because it can both draw in and blow air, depending on whether it is connected to the inlet or outlet. When the high-pressure blower 12 draws air outwards, without the graphite boat sheet loaded, air is drawn in from the microporous support plate 6 and extracted from the negative pressure chamber 8 through the negative pressure hole 20. When the graphite boat sheet is loaded, air is drawn in from the microporous support plate 6 and extracted from the negative pressure chamber 8 through the negative pressure hole 20. After extraction, the graphite boat sheet is firmly adhered to the microporous support plate 6 and cannot move, ensuring that the graphite boat sheet maintains its position and does not shift during subsequent engraving and grooving. The engraving device 3 includes a sliding base 13, a mounting bracket 14, and an engraving knife 15. The sliding base 13 is connected to the frame 1, and the lower end of the mounting bracket 14 is connected to the sliding base 13. The engraving knife 15 is mounted on the mounting bracket 14. The power system 4 includes a third motor 18 for controlling the vertical movement of the engraving knife 15, a second motor 17 for controlling the horizontal movement of the mounting bracket 14 on the sliding base 13, and a first motor 16 for controlling the forward and backward movement of the sliding base 13 on the frame 1.

[0030] The bottom of the receiving part 7 protrudes upward and is provided with a support platform 19, and the upper end of the support platform 19 is provided with a through negative pressure hole 20.

[0031] The cross-sectional area of ​​the support platform 19 on the horizontal plane becomes smaller and smaller. The support platform 19 has four inclined negative pressure adsorption and flow guiding sides 21, and there is an elongated hole 22 between two adjacent support platforms 19.

[0032] An elongated hole 22 is located in the center between two adjacent support platforms 19. The elongated hole 22 includes a reinforcing inclined surface in the same direction as the negative pressure adsorption and guiding side 21 on the same side. The two symmetrically arranged reinforcing inclined surfaces draw air outward through the high-pressure blower 12, and the air between the two adjacent support platforms 19 is drawn away. Due to the presence of the reinforcing inclined surfaces, a fan-shaped negative pressure attraction zone is formed. The fan-shaped negative pressure attraction zone strengthens the attraction force on the graphite boat portion located between the two support platforms 19, further enhancing the fixing effect on the graphite boat, so that the graphite boat does not shift during carving and grooving, preventing errors caused by the displacement of the graphite boat, and improving the accuracy of carving and grooving.

[0033] The microporous support plate 6 has symmetrical folded holes 23 on its left and right halves. Each folded hole 23 includes an upper folded portion 24 and a lower vertical hole 25 that are interconnected. The upper folded portions 24 on the left and right halves are mirror-symmetrical. The receiving portion 7 has a dust-guiding groove 26 corresponding to the support platform 19. The dust-guiding groove 26 is connected to the negative pressure chamber 8, and the height of the dust-guiding groove 26 increases towards the outer edge. By setting the dust-guiding groove with an inclined top surface, the dust particles generated after carving and grooving can be attracted and guided by the negative pressure airflow of the dust-guiding groove. This allows the dust to leave the graphite boat sheet during carving, ensuring that the graphite boat sheet is not affected by the dust particles generated during carving and grooving, thus affecting the accuracy of the next grooving step and ensuring the quality of grooving.

[0034] The top of the ash-guiding channel 26 is provided with an adjustable angle adjustment device 27. The angle adjustment device 27 includes a rotating plate 28, a vertical rod 29 axially connected to one end of the rotating plate 28, and a plate 30. The other end of the rotating plate 28 is axially connected to the top side wall of the ash-guiding channel 26. The vertical rod 29 is fixed to both ends of the upper surface of the plate 30. The lower surface of the plate 30 is in contact with the graphite boat sheet to be engraved and grooved. The axial connection protrusion rod 31 protrudes from the axial connection point between the rotating plate 28 and the vertical rod 29 toward the side wall of the nearest receiving part 7. The side wall of the receiving part 7 on the same side is provided with a corresponding limiting groove 32.

[0035] The extension line of the rotating plate 28 intersects the center line of the graphite boat piece to be carved and grooved. This enhances the suction effect.

[0036] The receiving part 7 has a dust removal hole 33 between the support platform 19 and the dust inlet channel 26. The dust removal hole 33 is connected to the dust removal channel 42, which is higher than the negative pressure chamber 8. This ensures that the removed dust does not affect the high-pressure blower 12.

[0037] The first motor 16 is mounted on the frame 1 and is connected to the first rotating screw 35 via a belt. The sliding base 13 is screwed to the first rotating screw 35 via a first slider 36. The bottom ends of the sliding base 13 are connected to the first slider 36. The frame 1 is provided with a first sliding groove 37 corresponding to the first slider 36, and the first slider 36 is connected to the first sliding groove 37. The second motor 17 is mounted on the sliding base 13 and is connected to the second rotating screw 38 via a belt. The mounting bracket 14 is connected to the second rotating screw 38 via a second slider 39. 8. A screw connection is made. The second slider 39 is mounted on the mounting bracket 14. The sliding base 13 has a second sliding groove 40 corresponding to the second slider 39, and the second slider 39 is connected to the second sliding groove 40. The third motor 18 is mounted on the mounting bracket 14 and is connected to the third rotating screw 43 via a belt. The mounting bracket 41 is screwed to the third rotating screw 43 via the third slider 44, and the mounting bracket 41 is connected to the third slider 44. The mounting bracket 14 has a third sliding groove 45 corresponding to the third slider 44, and the third slider 44 is connected to the third sliding groove 45. The belts are not shown in the accompanying drawings, but those skilled in the art can clearly understand the belt connection method from the drawings.
