A double-station ceramic wafer grinding device

Abstract

This invention belongs to the field of ceramic grinding technology, specifically a dual-station ceramic disc grinding device. It includes an outer frame with multiple stabilizing frames arranged in the middle. A flipping frame is located in the middle of the stabilizing frame via a flipping mechanism. The flipping frame has diagonally arranged clamping members at its four corners. The outer sides of the flipping frame are clamped to hold the edges and corners of ceramic discs of different specifications during grinding. When the control unit of this invention is activated, the flipping frame flips within the stabilizing frame. When the ground ceramic disc is flipped to face the ground, the conversion unit also activates simultaneously, causing the two vertical conversion plates in each group to alternate states accordingly. This ensures that the two lower conversion plates, parallel to the ground, always support the ground-facing side of the ceramic disc, while the two upper conversion plates keep the upper part of the flipping frame open. This allows for grinding one side of the ceramic disc, followed by flipping the disc to grind the back side of the grounded surface.

Description

Technical Field

[0001] This invention belongs to the field of ceramic grinding technology, specifically a dual-station ceramic disc grinding device. Background Technology

[0002] Ceramic sheets refer to thin sheet-like ceramic materials produced through processes such as molding and sintering. They are indispensable basic components in modern industry and high-tech fields. Based on function, ceramic sheets are mainly divided into the following categories: 1. Electronic ceramic sheets: such as alumina ceramic sheets, which are the most commonly used substrates for circuit boards and chip packaging; 2. Structural ceramic sheets: utilizing their high strength and wear resistance, they are used in mechanical seal rings, bearings, cutting tools, insulating parts of engine spark plugs, and high-temperature furnace liners; 3. Functional ceramic sheets: such as artificial bone joints, dental implants, high-intensity lighting (LED packaging), military protective windows, and honeycomb ceramic carriers in automotive exhaust purifiers. Sintered ceramic blanks (called "green blanks" or "sintered bodies") cannot directly meet the requirements for use. The surface after sintering is rough and may contain unevenness, burrs, or sintering defects, requiring grinding to obtain an ultra-smooth surface.

[0003] The prior art discloses a Chinese patent with application number CN120170591A, which discloses an automated ceramic grinding machine tool. It discloses that the driving mechanism drives two sets of components, namely the limiting mechanism and the reciprocating lead screw body, to operate. After the limiting mechanism limits and fixes the ceramic workpiece, the driving mechanism can drive the control seat and the position of the CNC grinding machine to be freely adjusted. This makes it more convenient for the CNC grinding machine to perform automated cutting on the ceramic workpiece, thereby improving the efficiency of the equipment during use.

[0004] While the aforementioned device is capable of grinding ceramics, it still has some drawbacks: The aforementioned device can only grind one ceramic disc at a time. When grinding a ceramic disc, both its upper and lower surfaces are usually ground. However, when grinding only one side, the ceramic disc must be clamped and fixed to prevent it from slipping during the grinding process. Therefore, after grinding one side, the ceramic disc must first be unfixed, then flipped over and fixed again. This repeated manual flipping and clamping greatly reduces processing efficiency. Furthermore, it is not suitable for grinding ceramic discs of different thicknesses. Summary of the Invention

[0005] The purpose of this invention is to provide a dual-station ceramic disc grinding device to solve the problems mentioned in the background art.

[0006] The objective of this invention can be achieved through the following technical solutions: A dual-station ceramic disc grinding device includes an outer frame, with multiple stabilizing frames arranged in the middle of the outer frame. A rotating frame is located in the middle of the stabilizing frames via a rotating mechanism. The rotating frame has diagonally arranged clamping members at its four corners. Clamping members on both sides of the rotating frame hold ceramic discs of different sizes for grinding. Two sets of vertically staggered conversion plates are rotatably mounted on both sides of the rotating frame. Each set of two conversion plates remains vertical during conversion. A changing mechanism is located on the outside of the rotating frame to adjust the position of the two conversion plates in each set. One side of the outer frame is electrically operated via a sliding mechanism. The block is slidably mounted with a displacement frame. Multiple external rods are rotatably mounted on the upper horizontal section of the displacement frame. A cross rod is vertically slidably mounted inside the external rod. A grinding disc for grinding ceramic discs is fixedly mounted at the bottom of the cross rod. A horizontal placement plate is provided on the upper part of the grinding disc. An internal ring that rotates inside the horizontal placement plate is fixedly mounted on the outside of the horizontal placement plate. A cleaning unit is provided on the upper part of the horizontal placement plate to suck up the dust generated by the grinding disc during operation. The displacement frame is also equipped with a position adjustment unit to adjust the height of the horizontal placement plate so as to meet the needs of grinding ceramic discs of different thicknesses.

[0007] The cleaning unit includes a cam fixed on an inner ring, an air box fixedly mounted on a horizontal plate, a piston slidably mounted in the middle of the air box, an arc-shaped block at one end of the piston that abuts against the cam, a spring sleeved on the piston, a filter box communicating with the horizontal plate fixedly mounted on the top of the horizontal plate, a suction pipe fixedly mounted on the bottom of the air box, one end of the suction pipe being connected to a side wall box rotatably connected to the upper outer side of the grinding disc, and multiple cleaning ports on the grinding disc.

[0008] The position adjustment unit includes a synchronization frame that is connected to multiple horizontally placed plates, and a rectangular frame that is fixed to the vertical section in the middle of the displacement frame. A vertically arranged threaded rod is mounted in the middle of the rectangular frame via a motor. An inner plate that slides on the rectangular frame is mounted on the outer thread of the threaded rod. The inner plate is cross-shaped and fixed to the synchronization frame. The top of the displacement frame is also equipped with a drive unit for driving multiple grinding discs to perform grinding operations synchronously.

[0009] The drive unit includes an electric push plate, an L-shaped component is fixedly installed at the telescopic end of the electric push plate, a control plate is fixedly installed at the bottom of the L-shaped component and meshes with a rotating wheel fixed to the outside of multiple external rods, a lower component is fixedly installed in the middle of the lower end face of the control plate, a fixing component is provided on the lower side of the control plate and fixedly installed on the side of the displacement frame, a stabilizing rod is fixedly installed on the fixing component, and the lower component is located outside the stabilizing rod and is slidably nested.

[0010] The clamping part includes two symmetrically arranged electric push rods. A control frame is fixedly installed at the far end of each of the two electric push rods. Sloping grooves are opened at both ends of the control frame. Vertical shafts are fixedly installed on the two symmetrical clamping parts of the horizontal section of the two conversion plates. The two vertical shafts slide and nest in the sloping grooves above them respectively.

[0011] The conversion unit includes a central wheel that is rotatably connected to the tilting frame via a motor. The upper and lower sides of the central wheel are meshed with staggered drive teeth. The drive teeth on both sides mesh with side wheels that rotate with the tilting frame and are symmetrically distributed on both sides of the central wheel. The side wheels on both sides are coaxially mounted with symmetrically distributed rotation control plates. The two ends of the rotation control plates are rotatably mounted with internal sliding parts. The upper and lower conversion plates of each group are provided with guide grooves. The two internal sliding parts on the rotation control plates slide within the guide grooves provided on the upper and lower conversion plates of each group.

[0012] When the two rotating control plates rotate closer to each other, the upper conversion plates in both groups rotate to a horizontal position with respect to the ground, and the corresponding lower conversion plates in both groups rotate to a vertical position with respect to the ground. Conversely, when the two rotating control plates rotate further apart, the two upper conversion plates are perpendicular to the ground and open the upper part of the tilting frame. Conversely, the two lower conversion plates are parallel to the ground and close the lower part of the tilting frame.

[0013] Side members are fixedly installed on both sides of the tilting frame. A shaft is fixedly installed at the far end of each side member. An inner support plate is located inside the stabilizer and used to support the shaft. A traction plate is rotatably installed on the close side of each inner support plate. The end of the traction plate away from the inner support plate is rotatably connected to the corresponding side member. A prying frame is installed on the outside of the shafts on both sides. Support members are fixed to the stabilizer and rotate inside the middle of the side of the prying frame on both sides. A control unit is connected to the multiple prying frames to push down the prying frames so as to tilt the tilting frame inside the stabilizer.

[0014] The control unit includes a cylinder fixed inside the external frame, and a kit located outside the prying frame is fixedly mounted on the top of the cylinder.

[0015] While the control unit controls the tilting frame to tilt within the stabilizing frame, the transformation unit controls the position of the upper and lower transformation plates to change. When the tilting frame completes its tilting within the stabilizing frame, the alternation between the upper and lower transformation plates is completed.

[0016] The beneficial effects of this invention are: 1. This invention uses multiple clamping components positioned close to or far apart from each other to clamp the four corner edges of ceramic sheets of different specifications during grinding operations. The flipping frame flips within the stabilizing frame, ensuring that the ceramic sheet with one side already ground faces the grinding disc after being flipped so that it will not fall off during the flipping process. Furthermore, when the clamping components clamp the sides of the ceramic sheet, they are always lower than the top surface of the ceramic sheet. Therefore, when multiple clamping components clamp the ceramic sheet after the conversion plates at the two bottoms are placed, they will not interfere with the grinding disc when grinding the surface of the ceramic sheet.

[0017] 2. This invention enables the control unit to activate and rotate the rotating frame within the stabilizing frame. When the ceramic sheet that has been ground is rotated to face the ground, the conversion unit also activates simultaneously, causing the two vertical conversion plates in each group to alternate states accordingly. This ensures that the two conversion plates at the bottom, parallel to the ground, can always support the side of the ceramic sheet facing the ground. Furthermore, the two conversion plates on both sides of the ceramic sheet facing the grinding surface of the grinding disc, which are perpendicular to the ground, can reserve space for the grinding disc. In other words, the two conversion plates at the top open the upper part of the rotating frame, enabling continuous grinding of the back side of the ground ceramic sheet after grinding one side by rotating the ceramic sheet.

[0018] 3. In this invention, when the grinding disc is rotated by an external rod via a crossbar to grind the surface of the ceramic sheet, the crossbar also drives the cam to rotate simultaneously. When the cam rotates, it intermittently squeezes the arc-shaped block at one end of the piston. When the arc-shaped block is squeezed, it compresses the air box through the piston. When the cleaning port at the bottom of the grinding disc comes into contact with the surface of the ceramic sheet, it sucks in the dust from the surface of the ceramic sheet. Finally, the dust generated during grinding is sucked into the filter box. When the motor is turned on, it drives the threaded rod to rotate. When the threaded rod rotates, it drives the built-in plate to move up and down on the rectangular frame, which can meet the grinding needs of ceramic sheets of different thicknesses.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figure 1-10As shown, this invention is a dual-station ceramic disc grinding device, including an outer frame 1. Multiple stabilizing frames 10 are arranged in the middle of the outer frame 1. A rotating frame 11 is provided in the middle of the stabilizing frame 10 via a rotating part. Clamping members 13 are arranged diagonally at the four corners of the rotating frame 11. The outer sides of the rotating frame 11 clamp ceramic discs of different specifications for edge and corner clamping during grinding via clamping parts. Specifically, before grinding the ceramic disc, it is first placed on two lower conversion plates 12. Since the lower conversion plates 12 are parallel to the ground, they can initially support the ceramic disc during grinding, allowing the multiple clamping members 13 to approach and clamp the ceramic disc. The positions of the multiple clamping members 13 can be adjusted to allow for closer or farther proximity, thus satisfying the requirements for grinding ceramic discs of different specifications. The ceramic sheet is clamped at the four corner edges and simultaneously clamped by multiple clamping members 13. The flipping frame 11 can also be flipped within the stabilizing frame 10. When the ceramic sheet with one side polished is flipped so that the unpolished ceramic surface faces the polishing disc 25 for polishing, the ceramic sheet will not fall off when the flipping frame 11 is flipped. When the clamping members 13 clamp the sides of the ceramic sheet, the clamping members 13 are always lower than the top surface of the ceramic sheet. Therefore, when the multiple clamping members 13 clamp the ceramic sheet after the conversion plates 12 at the two bottoms are placed, they will not interfere with the polishing disc 25 when polishing the polishing surface of the ceramic sheet. Furthermore, the polishing disc 25 is located on the polishing surface of the ceramic sheet and performs a covering polishing. Therefore, it can meet the corresponding requirements of the multiple clamping members 13 for polishing ceramic sheets of different specifications after clamping. Two sets of vertically intersecting conversion plates 12 are rotatably mounted on both sides of the flipping frame 11. Each set of two conversion plates 12 is always in a vertical state during conversion. The outside of the flipping frame 11 is provided with a conversion part for adjusting the state of the two conversion plates 12 in each set. When grinding one side of a ceramic sheet, and then grinding the back side of the ground surface, the control unit is activated to rotate the tilting frame 11 within the stabilizing frame 10. When the ground ceramic sheet is rotated to face the ground, the conversion unit is also activated simultaneously to allow the two vertical conversion plates 12 in each group to alternate states. This ensures that the two lower conversion plates 12, which are parallel to the ground, can always support the side of the ceramic sheet facing the ground. At this time, the two conversion plates 12 on both sides of the grinding surface of the ceramic sheet facing the grinding disc 25, which are perpendicular to the ground, can reserve space for the grinding disc 25. That is, the two upper conversion plates 12 open the upper part of the tilting frame 11. A displacement frame 2 is slidably mounted on one side of the external frame 1 via an electric slider. Multiple external rods 21 are rotatably mounted on the upper horizontal section of the displacement frame 2. A cross rod 22 is vertically slidably mounted inside the external rod 21. A grinding disc 25 for grinding ceramic discs is fixedly mounted at the bottom of the cross rod 22. A horizontal placement plate 23 is provided on the upper part of the grinding disc 25. An internal ring 24 that rotates inside the horizontal placement plate 23 is fixedly mounted on the outside of the horizontal placement plate 23. A cleaning unit for sucking up the dust generated by the grinding disc 25 during operation is provided on the upper part of the horizontal placement plate 23. When the external rod 21 rotates, it can synchronously drive the grinding disc 25 to rotate, thereby realizing the grinding operation of the ceramic disc below the grinding disc 25. It should be noted that when the ceramic disc is flipped after one side is ground, the electric slider is activated to drive the displacement frame 2 to lift upward on the side of the external frame 1, thereby moving the grinding disc 25 upward and leaving enough space for the flipping frame 11 to flip within the stabilizing frame 10. When the external rod 21 rotates, it can also synchronously clean the unit, so that the dust generated by the grinding disc 25 during the grinding of the ceramic disc can be collected uniformly. The displacement frame 2 is also equipped with a position adjustment unit for adjusting the height of the horizontal placement plate 23 so as to meet the requirements for grinding ceramic sheets of different thicknesses; By setting the position adjustment unit, the cross bar 22 can drive the grinding disc 25 to move up and down, so that the grinding disc 25 can perform grinding operations on ceramic discs of different thicknesses. The cleaning unit includes a cam 26 fixed on the inner ring 24, an air box 27 fixedly installed on the horizontal plate 23, a piston 28 slidably installed in the middle of the air box 27, an arc-shaped block abutting against the cam 26 at one end of the piston 28, and a spring sleeved on the piston 28, a filter box 29 communicating with the horizontal plate 23 fixedly installed on the top of the horizontal plate 23, a suction pipe 271 fixedly installed at the bottom of the air box 27, one end of the suction pipe 271 connected to a side wall box 272 rotatably connected to the upper outer side of the grinding disc 25, and a plurality of cleaning ports 251 provided on the grinding disc 25.

[0024] When the external rod 21 drives the grinding disc 25 to rotate via the cross rod 22 to grind the surface of the ceramic sheet, the cross rod 22 also synchronously drives the cam 26 to rotate. When the cam 26 rotates, it intermittently squeezes the arc-shaped block at one end of the piston 28. When the arc-shaped block is squeezed, it compresses the gas in the air box 27 through the piston 28. When the gas in the air box 27 is compressed, it generates a suction force in the side wall box 272 through the suction pipe 271. The side wall box 272 rotates with the external rotation of the grinding disc 25. Therefore, while not affecting the rotation of the grinding disc 25 to grind the ceramic sheet, it can also clean the ceramic sheet when the cleaning port 251 at the bottom of the grinding disc 25 comes into contact with the ceramic sheet surface. Dust on the surface of the ceramic disc is sucked in and eventually drawn into the filter box 29. The filter box 29 has a removable filter screen, and the filter screen can be replaced to clean the filter box 29 when too much dust is collected. The cleaning port 251 has multiple ports and is arranged in a staggered manner on the grinding contact surface of the grinding disc 25. Therefore, it can ensure that the multiple grinding contact surfaces of the grinding disc 25 are fully ground with the ceramic disc, and at the same time, it can ensure that the cleaning port 251 collects the dust generated on the ceramic disc multiple times when the grinding disc 25 rotates on the ceramic disc to ensure effective cleaning of the dust on the ceramic disc. The position adjustment unit includes a synchronization frame 231 connected to multiple horizontally placed plates 23, and a rectangular frame 232 fixed to the vertical section in the middle of the displacement frame 2. A vertically arranged threaded rod 233 is rotatably mounted in the middle of the rectangular frame 232 via a motor. An inner plate 234 that slides on the rectangular frame 232 is rotatably mounted on the outer thread of the threaded rod 233. The inner plate 234 is cross-shaped and fixed to the synchronization frame 231. The top of the displacement frame 2 is also provided with a drive unit for driving multiple grinding discs 25 to perform grinding operations synchronously.

[0025] When the height of the grinding disc 25 is adjusted to accommodate ceramic sheets of different thicknesses, the motor is turned on, causing the threaded rod 233 to rotate. As the threaded rod 233 rotates, it causes the inner plate 234 to move up and down on the rectangular frame 232. As the inner plate 234 moves up and down, it drives the synchronous frame 231. As the synchronous frame 231 moves up and down, it synchronously drives multiple horizontally placed plates 23 to move up and down. As the multiple horizontally placed plates 23 move up and down, they respectively drive the corresponding cross rods 22 to move up and down within the outer rod 21. As the cross rods 22 move up and down, they drive the grinding disc 25 to adjust its position to meet the grinding needs of ceramic sheets of different thicknesses. Furthermore, by adjusting the height of the grinding disc 25, different grinding forces can be applied to the ceramic sheets, thus making the grinding process of ceramic sheets more versatile. The drive unit includes an electric push plate 31. An L-shaped part 32 is fixedly installed at the telescopic end of the electric push plate 31. A control plate 33 that meshes with a rotating wheel 3 fixed to the outside of a plurality of external rods 21 is fixedly installed at the bottom of the L-shaped part 32. A lower component 34 is fixedly installed in the middle of the lower end face of the control plate 33. A fixing member 35 that is fixedly installed to the side of the displacement frame 2 is provided on the lower side of the control plate 33. A stabilizing rod 36 is fixedly installed on the fixing member 35. The lower component 34 is located outside the stabilizing rod 36 and is slidably nested.

[0026] When multiple grinding discs 25 are grinding ceramic discs, the electric push plate 31 is activated for telescopic operation. During telescopic operation, the electric push plate 31 drives the control plate 33 via the L-shaped component 32, causing multiple rotating wheels 3 to rotate. The rotating wheels 3 simultaneously drive the external rod 21 to rotate. Furthermore, when the L-shaped component 32 moves horizontally, it slides on the stabilizing rod 36 via the lower component 34. The stabilizing rod 36 also provides stable guidance to the control plate 33. The rotation of the external rod 21 simultaneously drives the cross rod 22 to rotate, and the rotation of the cross rod 22 simultaneously drives the grinding discs 25 to rotate, thus... The surface of the ceramic sheet is being ground. Since the inner ring 24 rotates with the cross rod 22 and is rotatably connected within the horizontal placement plate 23, while the cross rod 22 slides up and down within the outer rod 21, when the horizontal placement plate 23 moves the inner ring 24 up and down, the cross rod 22 also moves up and down within the outer rod 21 along with the horizontal placement plate 23. This allows the cross rod 22 to both drive the grinding disc 25 to rotate and to move up and down within the outer rod 21 with the position adjustment unit. The clamping part includes two symmetrically arranged electric push rods 131. A control frame 132 is fixedly installed at the far end of each of the two electric push rods 131. An inclined groove 133 is opened at both ends of the control frame 132. Vertical shafts 134 are fixedly installed on the two symmetrical clamping members 13 of the horizontal section of the two conversion plates 12. The two vertical shafts 134 are respectively located in the inclined grooves 133 above them and slide nested.

[0027] When ceramic discs of different specifications are clamped in the flipping frame 11, the electric push rods 131 on both sides are extended and retracted. When the electric push rods 131 on both sides retract, they drive the control frames 132 on both sides to move closer to each other. The inclined grooves 133 on the control frames 132 push the vertical shaft 134. When the vertical shaft 134 is pushed, it drives the clamping parts 13 to move. The control frames 132 on both sides drive the two corresponding clamping parts 13 to move closer to the center of the ceramic disc. At this time, the four clamping parts 13 move closer to each other until they clamp the four corner edges of the ceramic disc. When the electric push rods 131 on both sides are opened and pushed forward, the control frames 132 on both sides drive the two corresponding clamping parts 13 to move away from each other, and gradually move away along the diagonal of the ceramic disc, losing the clamping of the ceramic disc, so that the ceramic disc that has completed the grinding operation can be picked up. The conversion unit includes a central wheel 122 rotatably connected to the tilting frame 11 via a motor. The upper and lower sides of the central wheel 122 are meshed with staggered drive teeth 123. The drive teeth 123 on both sides mesh with side wheels 124 that rotate with the tilting frame 11 and are symmetrically distributed on both sides of the central wheel 122. The side wheels 124 on both sides are coaxially rotatably mounted with symmetrically distributed rotation control plates 125. The two ends of the rotation control plates 125 are rotatably mounted with internal sliding parts 126. Each set of upper and lower conversion plates 12 is provided with guide grooves 121. The two internal sliding parts 126 on the rotation control plates 125 slide within the guide grooves 121 provided on the upper and lower conversion plates 12 of each set.

[0028] When the conversion unit cooperates with the control unit to control the tilting frame 11 to tilt within the stabilizer frame 10, the motor is turned on to drive the center wheel 122 to rotate. When the center wheel 122 rotates, it drives the meshing drive teeth 123 on its upper and lower sides to move closer or further apart. This causes the drive teeth 123 on the upper and lower sides to drive the side wheels 124 on both sides to rotate closer or further apart. When the side wheels 124 on both sides rotate closer together, they drive the rotation control plates 125 on both sides to tilt closer together. This causes the state of the two interlaced conversion plates 12 to change. When the rotation control plates 125 on both sides rotate closer together, they slide in the corresponding guide grooves 121 through the internal sliding parts 126 on their upper and lower sides. When the two rotating control plates 125 rotate closer to each other, the upper conversion plates 12 of the two sets rotate to a horizontal state with respect to the ground, and the corresponding middle and lower conversion plates 12 of the two sets rotate to a vertical state with respect to the ground. Conversely, when the two rotating control plates 125 rotate further apart, the two upper conversion plates 12 are perpendicular to the ground and open the upper part of the tilting frame 11. Conversely, the two lower conversion plates 12 are parallel to the ground and close the lower part of the tilting frame 11.

[0029] Side members 14 are fixedly installed on both sides of the tilting frame 11. A shaft 15 is fixedly installed at the far end of each side member 14. An inner support plate 16 is provided below the shaft 15, which is fixed inside the stabilizer 10 and used to support the shaft 15. A traction plate 17 is rotatably installed on the close side of each inner support plate 16. The end of the traction plate 17 away from the inner support plate 16 is rotatably connected to the corresponding side member 14. A prying frame 18 is installed on the outside of the shafts 15 on both sides. A support member 181 is provided on both sides of the prying frame 18, which is fixed to the stabilizer 10 and rotates inside the middle of the side of the prying frame 18. A control unit is connected among the multiple prying frames 18 to push down the prying frame 18 so as to tilt the tilting frame 11 inside the stabilizer 10.

[0030] The control unit includes a cylinder 182 fixed inside the outer frame 1, and a kit 183 located outside the prying frame 18 is fixedly mounted on the top of the cylinder 182 and rotatably connected to it.

[0031] When the tilting frame 11 is tilted within the stabilizing frame 10, the opening assembly 183 retracts. When the assembly 183 retracts, the cylinder 182 presses down on the prying frame 18. When the prying frame 18 is pressed down, it tilts between the two corresponding support members 181 on the stabilizing frame 10. At this time, the prying frame 18 drives the shaft 15 to lift up so that it is separated from the inner support plate 16. At this time, the tilting frame 11 is also lifted up within the stabilizing frame 10. When the tilting frame 11 is lifted up, the side member 14 is moved up simultaneously, thereby pulling the traction plate 17 to rotate. Under the action of the traction plate 17, the tilting frame 11 is tilted within the stabilizing frame 10. When the tilting frame 11 has finished tilting, the control assembly 183 moves up to reset. At this time, one side of the prying frame 18 loses the downward pressure. The prying frame 18 drives the tilting frame 11 to be placed on the inner support plate 16 again through the shaft 15. While the control unit controls the flipping frame 11 to flip within the stabilizing frame 10, the transformation unit controls the position of the upper and lower transformation plates 12 to change. When the flipping frame 11 completes the flipping within the stabilizing frame 10, the alternation of the states between the upper and lower transformation plates 12 is completed.

[0032] The above description is merely an example and illustration of the concept of the present invention. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the concept of the invention or exceed the scope defined in the claims, they should all fall within the protection scope of the present invention.
