[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] In a specific embodiment, Figure 1-Figure 6 As shown, the automatic working process of the all-in-one machine is disclosed; A protective base 1 and a protective cover 2 fixedly mounted on the upper end of the protective base 1; A switch door 3 is slidably installed inside the protective cover 2, a fixed base 4 is fixedly installed inside the protective base 1, a driving motor 7 is fixedly installed on the upper end of the fixed base 4, and a rotating shaft 9 is fixedly installed on the output end of the driving motor 7, and the rotating shaft 9 is rotatably installed on the upper end of the fixed base 4, and a moving block 8 is threadedly installed on the outer side of the rotating shaft 9; A rotating motor 17 is mounted on the outer side of the moving block 8, and a vacuum suction cup 18 is rotatably mounted on the upper end of the rotating motor 17. A vent pipe 5 is fixedly mounted on the upper end of the protective cover 2. A mounting frame 15 is fixedly mounted on the upper end of the protective base 1, and the mounting frame 15 is located inside the protective cover 2. An input unit 10 is fixedly installed on the outer side of the fixed base 4, and the input unit 10 is located inside the protective cover 2, and a touch screen is provided on the upper end of the input unit 10. A limit guide rail 6 is fixedly installed on the upper end of the fixed base 4, and the limit guide rail 6 is slidably connected to the rotating motor 17.

[0018] During the use of the integrated machine, the ingot needs to be placed on the upper end of the vacuum suction cup 18, and then the laser projector 16 can project the aperture on the ingot, and the ingot and the suction cup can be adjusted by naked eyes to see whether they are concentric. The concentric circles projected by the laser and the suction cup are concentric, which is more accurate. The adjustment of the ingot is mainly to make the outer circle of the ingot and the nearest projection circle overlap as much as possible. At the same time, because the specification of the ingot blank is 162MM, it is required to be processed to 150.2MM, which has enough size and will not affect the finished workpiece; After the ingot is placed, the vacuum chuck 18 can be used to absorb and position the ingot. The grinding member 14 is a grinding wheel of three different sizes, which can realize the end face grinding and outer circle grinding of the ingot. The X axis of the grinding member 14 drives the grinding wheel to swing back and forth on the ingot, and the Z axis feeds downward. When the lower knife reaches the set thickness, the grinding stops and each axis stops at its own safety position. During the external cylindrical grinding of the ingot, the grinding wheel for external cylindrical grinding sticks to the outer circle of the ingot and swings up and down. The X-axis feeds and the C-axis grinding wheel rotates all the time. When the X-axis reaches the set value, it stops at the respective safety positions. After the above two processes are completed, it becomes a complete cylinder. Next, the orientation instrument is used to find the deviation value of the end face and the position of the positioning edge of the cylinder. After measuring these two values, the silicon carbide rod is trimmed. The orienting instrument assembly 21 is provided with a cylindrical orienting instrument and an end face orienting instrument inside, which can perform orientation measurement; During the growth of silicon carbide crystals, there is a certain deviation angle between the growth direction and the crystal orientation. In simple terms, the silicon carbide crystal sheet is a standard disc from a macroscopic point of view, but from a microscopic point of view, the internal crystal structure is not necessarily completely vertical. Therefore, it is necessary to orient the crystal, and then adjust the angle of the processing table to ensure that the microscopic internal crystal structure is used during processing. X-rays are used as a means of orientation detection. Before the orientation instrument assembly 21 is used for measurement, the distance between the X-ray and the ingot is 50±0.01MM, the angle of the X-ray injection cannot be changed, the surface of the workpiece to be measured must be clean and free of water stains, and the orientation instrument orientation is divided into 4 steps and only needs to be started with one button; At the same time, the operator can observe the processing status of the silicon carbide crystal through the multiple switch doors 3, which is convenient for the operator to observe from multiple angles.

[0019] In one specific embodiment, Figure 1-Figure 8 As shown, the process of multi-angle processing by the integrated machine is disclosed; A fixed vertical plate 11 is fixedly installed on the upper end of the protection base 1, and a directional guide rail 19 and a horizontal motor 27 are fixedly installed on one end of the fixed vertical plate 11 close to the rotating motor 17, and a moving plate 12 and a vertical guide rail 26 are slidably installed on the outer side of the directional guide rail 19; An adjustment plate 24 is slidably mounted on one end of the vertical guide rail 26 away from the directional guide rail 19, and a driving member 13 and an orienting instrument assembly 21 are fixedly mounted on one end of the adjustment plate 24 away from the directional guide rail 19, and a grinding member 14 is fixedly mounted on the output end of the driving member 13, and is located on the left side of the vacuum suction cup 18; A rotary motor 23 is provided at the lower end of the orientation instrument assembly 21, and the output end of the rotary motor 23 is fixedly connected to the rotary motor 17, and the upper end of the orientation instrument assembly 21 is connected to the air vent 5, and a laser projector 16 is fixedly installed on the outer side of the orientation instrument assembly 21; A servo motor 25 is fixedly mounted on the upper end of the fixed vertical plate 11 , and an output end of the servo motor 25 is connected to a vertical guide rail 26 on the outer side of the driving member 13 .

[0020] The rotary table is driven by a rotating motor 17 and is equipped with a rotary encoder, which can accurately locate the rotation angle and stop using pneumatic brakes and brake discs. It has good stability and accurate positioning. The table moves back and forth on the limit guide rail 6, adding a variety of grinding methods to facilitate the processing of outer circles and cutting angles. The laser projector 16 is powered on to generate red light, which is gathered by the spotlight cover. The lampshade is pasted with reflective paper, so that the light passes through the scale gap of the mask and is projected on the surface of the silicon carbide blank. Because silicon carbide is cast through a mold ingot, the shape of the outer surface is inconsistent. The operator needs to adjust the silicon carbide according to the scale line so that the entire circle of light is on the silicon carbide, and then open the solenoid valve of the vacuum suction cup 18 to suck the silicon carbide crystal, and then run the program to grind the upper surface and outer circle of the silicon carbide. After grinding the outer circle, a complete cylinder can be formed. After the outer circle and crystal of silicon carbide are ground, the transverse motor 27 automatically controls the inward and outward movement of the detection head so that the indicator needle of the orientation instrument assembly 21 touches the outer circle of silicon carbide. The laser head emits laser, and the workbench starts to rotate slowly under the drive of the drive motor 7. The laser receiver 16 receives the laser emitted by the laser transmitter into the silicon carbide crystal, and determines the polarity position of silicon carbide through the received laser data. When the polarity orientation is accurate, the motor stops and the pneumatic brake is turned on to fix the entire workbench. Then the grinding piece 14 is ground with a knife, and the workbench moves back and forth to grind millimeter incisions at the polarity position. The movable cart can realize automated detection and shaping of silicon carbide crystals with high accuracy and easy use.

[0021] Based on the above embodiments, Figure 2-Figure 7 As shown, the automatic collection process of the all-in-one machine is disclosed; A discharge plate 22 is fixedly installed inside the protective base 1, and one end of the discharge plate 22 away from the protective base 1 is located outside the protective base 1, and a guide plate 20 is fixedly installed inside the protective base 1, and the guide plate 20 is located at the upper end of the discharge plate 22.

[0022] When using the silicon carbide crystal special shaping machine, the silicon carbide crystal powder will be scattered on the upper end of the guide plate 20, and the interior of the guide plate 20 is recessed downward, and the recessed part at the lower end of the guide plate 20 is open, which will cause the silicon carbide crystal powder to be scattered through the opening to the upper end of the discharge plate 22. At this time, the silicon carbide crystal powder can be cleaned up centrally, which increases the overall practicality.
