Description

Technical Field

[0001] This invention relates to the field of graphite production, and more specifically to a feeding device for a semiconductor cylindrical graphite precision grinding equipment. Background Technology

[0002] Graphite, an allotrope of carbon, is chemically stable and possesses rich industrial properties, making it widely used in production and daily life. Graphene, a product of graphite raw materials, exhibits excellent performance and is considered a revolutionary material for the future. The enormous industrial potential of graphite and graphene products has driven the vigorous development of the graphite production and processing industry. In the production of semiconductor graphite products, a process involves cutting square-section semiconductor graphite rods into cylindrical graphite rods. This process typically uses a pusher-type feeder. However, the semiconductor cylindrical graphite after the first cutting is generally quite rough, and its surface smoothness does not yet meet the requirements for use. Therefore, further fine grinding is necessary. Because the semiconductor cylindrical graphite is smaller after the first grinding, it tends to accumulate during feeding by the pusher-type feeder. This often results in multiple cylindrical graphite rods being pushed into the feed section of the fine grinding equipment, requiring rearrangement of the semiconductor cylindrical graphite on the surface of the feed section to prevent them from entering the fine grinding equipment simultaneously, significantly impacting the processing efficiency of semiconductor products. Summary of the Invention

[0003] This invention provides a feeding device for a semiconductor cylindrical graphite fine grinding equipment, which avoids material accumulation during the fine grinding of graphite rods, thereby stabilizing the feeding of the fine grinding equipment and improving processing efficiency.

[0004] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a feeding device for a semiconductor cylindrical graphite fine grinding equipment, comprising a feeding plate, a lifting section, and a feeding plate. The lifting section includes a lifting rod, a lifting arc plate, and an auxiliary straight plate. The auxiliary straight plate is a flat plate extending vertically downward from the upper edge of the feeding plate. The lifting arc plate is an arc-shaped plate with an upward concave opening. The upper end of the lifting rod is connected to the lifting arc plate, and the lower end of the lifting rod is connected to the motor shaft end. The auxiliary straight plate has vibration-dropping protrusions, which are spherical protrusions protruding outward from the surface of the auxiliary straight plate.

[0005] Preferably, the lifting arc plate and the lifting rod are connected by a telescopic transition part, which is used to maintain the stability of the material on the surface of the lifting arc plate.

[0006] Preferably, the telescopic conversion part includes a conversion groove, a telescopic plate, a sleeve rod groove, and a pushing column. The conversion groove is a through groove extending downward from both sides of the lifting arc plate to the arc panel that connects with the lifting arc plate. The telescopic plate is an arc-shaped panel. The telescopic plate is inserted into the conversion groove on both sides through cylindrical inserts on both sides of the edge. The sleeve rod groove is a hollow frame extending downward at an incline from the bottom surface of the telescopic plate. The pushing column is horizontally mounted in the sleeve rod groove on both sides, and the middle part of the pushing column is connected to the lifting rod.

[0007] Preferably, the sleeve groove also has a rod embedding groove, which is an arc-shaped groove that is recessed from the groove wall where the sleeve groove contacts the telescopic plate to the side near the material feeding plate.

[0008] Preferably, the telescopic plate also has a soothing surface that protects the material surface.

[0009] Preferably, the soothing surface is a flat plate that extends in the opposite direction from the edge of the telescopic plate near the feeding plate.

[0010] Preferably, the bottom surface of the lifting arc plate also has a slow-moving groove to prevent the telescopic plate from sliding too quickly.

[0011] Preferably, the easing groove is a cross-shaped straight groove that is recessed inward from the bottom surface of the lifting arc plate.

[0012] In summary, the present invention has the following beneficial effects.

[0013] 1. Graphite rods and other materials on the feeding plate will accumulate on the surface of the lifting arc plate. During the upward process, the lifting arc plate will come into contact with the shaking protrusions on the surface of the auxiliary straight plate and vibrate, shaking off the extra material on the surface of the lifting arc plate. This ensures that the lifting arc plate lifts one graphite rod at a time, ensuring stable material reception at the feed section of the precision grinding equipment and improving processing efficiency.

[0014] 2. During the process of the telescopic plate extending from the conversion slot, it can separate the adjacent graphite rods to prevent adjacent graphite rods from being lifted at the same time. At the same time, the upward-bending telescopic plate can better protect and limit the graphite rods located on the surface of the lifting arc plate, preventing them from accidentally falling off the surface of the lifting arc plate when it passes the shaking off the protruding particles.

[0015] 3. The grooved insert allows the push rod to be stably embedded when it rises to the top of the sleeve groove, making the push plate pushed by the lifting rod more stable and preventing the push rod from slipping on the sleeve groove wall.

[0016] 4. The smoothing surface increases the contact area of ​​the telescopic plate when pushing adjacent graphite rods or other materials outward, preventing excessive pressure on the graphite rod surface from damaging it. Furthermore, the smoothing surface increases the mass of the outer end of the telescopic plate, thus providing additional weight and momentum for retraction when the plate fully extends from the conversion slot, making retraction easier.

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0026] Example 1

[0027] like Figures 1 to 6As shown, a feeding device for a semiconductor cylindrical graphite precision grinding equipment includes a feeding plate 1, a lifting section, and a feeding plate 2. The lifting section includes a lifting rod 3, a lifting arc plate 4, and an auxiliary straight plate 5. The auxiliary straight plate 5 is a flat plate extending vertically downward from the upper edge of the feeding plate 2. The lifting arc plate 4 is an arc-shaped plate with an upward concave opening. The upper end of the lifting rod 3 is connected to the lifting arc plate 4, and the lower end of the lifting rod 3 is connected to the motor shaft end. The auxiliary straight plate 5 has shaken-off protrusions 6, which are spherical protrusions protruding outward from the surface of the auxiliary straight plate 5. The graphite rods and other materials on the feeding plate 1 will accumulate on the surface of the lifting arc plate 4. At this time, the motor shaft end will perform a telescopic movement, which will drive the lifting rod 3 to move up and down, pushing the lifting arc plate 4 to move up and down to transport the graphite rods. During the upward movement, the lifting arc plate 4 will come into contact with the shaking protrusions 6 located on the surface of the auxiliary straight plate 5 and vibrate, shaking off the extra material on the surface of the lifting arc plate 4, ensuring that the lifting arc plate 4 lifts one graphite rod at a time, and ensuring the stable material receiving of the feed part of the fine grinding equipment.

[0028] The lifting arc plate 4 and the lifting rod 3 are connected by a telescopic transition part, which is used to maintain the stability of the material on the surface of the lifting arc plate 4.

[0029] The telescopic conversion section includes a conversion groove 7, a telescopic plate 8, a sleeve rod groove 9, and a pushing column 10. The conversion groove 7 is a through groove that extends downward from both sides of the lifting arc plate 4 to the arc plate and the lifting arc plate 4. The telescopic plate 8 is an arc-shaped panel. The telescopic plate 8 is inserted into the conversion groove 7 on both sides through cylindrical inserts on both sides of the edge. The sleeve rod groove 9 is a hollow frame that extends downward at an incline from the bottom surface of the telescopic plate 8. The pushing column 10 is horizontally mounted in the sleeve rod groove 9 on both sides. The middle part of the pushing column 10 is connected to the lifting rod 3. In the initial state, the lifting rod 3 is in a low position, pulling down the extrusion column 10 so that the extrusion column 10 is located at the lower end of the sleeve groove 9. At this time, the telescopic plate 8 is located in the conversion groove 7. When the lifting rod 3 rises, it pushes the inclined sleeve groove 9, causing the telescopic plate 8 to move in the conversion groove 7. The outer edge of the telescopic plate 8 extends towards the feeding plate 1 until the cylindrical insert touches the end of the conversion groove 7. At this time, as the lifting rod 3 continues to rise, the lifting arc plate 4 and the telescopic plate 8 rise simultaneously, lifting the graphite rod or other materials located on the surface of the lifting arc plate 4 until the graphite rod is sent to the upper feeding plate 2. During the extension of the telescopic plate 8 from the conversion slot 7, it can separate adjacent graphite rods, preventing them from being lifted simultaneously. Simultaneously, the upward-curving telescopic plate 8 provides better protection and restraint for the graphite rods located on the surface of the lifting arc plate 4, preventing them from accidentally falling off the surface of the lifting arc plate 4 when it passes the dislodged protrusions 6. When the lifting rod 3 retracts, the telescopic plate 8 gradually retracts into the conversion slot 7. The pushing column 10 descends to its lower end in the sleeve groove 9, pulling the telescopic plate 8 downwards, ensuring it is completely retracted into the conversion slot 7, ready for the next material lifting operation. Specifically, as... Figure 3As shown, when the sleeve groove 9 descends, the graphite rod below can be squeezed by the arc surface at the lower end. Since the telescopic plate 8 can move flexibly in the conversion groove 7, the squeezing force will not be very large, pushing the graphite rod away from the extrusion column 10, which facilitates the descent and reset of the lifting arc plate 4.

[0030] The sleeve groove 9 also has a rod-embedding groove 11, which is an arc-shaped groove recessed from the groove wall where the sleeve groove 9 contacts the telescopic plate 8 towards the side near the discharge plate 1. The rod-embedding groove 11 allows the extrusion column 10 to be stably embedded when it rises to the top of the sleeve groove 9, making it more stable when the lifting rod 3 pushes the telescopic plate 8, and preventing the extrusion column 10 from slipping on the wall of the sleeve groove 9.

[0031] The telescopic plate 8 also has a soothing surface 12 to protect the material surface.

[0032] The smoothing surface 12 is a flat plate that extends in the opposite direction from the edge of the telescopic plate 8 near the discharge plate 1. The smoothing surface 12 can increase the contact area of ​​the telescopic plate 8 when it pushes adjacent graphite rods and other materials outward, preventing excessive pressure on the surface of the graphite rods and thus preventing damage. In addition, the setting of the smoothing surface 12 increases the mass of the outer end of the telescopic plate 8, thereby increasing the weight force for retraction when the telescopic plate 8 needs to be retracted after it has fully extended out of the conversion slot 7, making it easier to retract.

[0033] There is also a slow-moving groove on the bottom surface of the lifting arc plate 4 to prevent the telescopic plate 8 from sliding too quickly.

[0034] The easing groove is a cross-shaped straight groove that is recessed inward on the bottom surface of the self-lifting arc plate 4. In the initial stage when the lifting rod 3 rises and lifts the lifting arc plate 4, the telescopic plate 8 will be squeezed and extended outward. At this time, due to the presence of the easing groove, the bottom surface of the lifting arc plate 4 has a good roughness, which prevents the cylindrical insert rod from slipping on the bottom surface of the lifting arc plate 4, ensuring that the telescopic plate 8 extends stably, and the easing surface 12 that abuts against the surface of the adjacent graphite rod is also stably squeezed and pushed.
