Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of sheet grinding, and specifically relates to a grinding device, a grinding method and a sheet processing technology for sheet processing. Background Art
[0002] Grinding is a mechanical processing method for removing materials. It refers to the processing method of removing excess materials on the workpiece with abrasives and grinding tools. Grinding processing is one of the widely used material removal methods; for the processing method of removing excess materials on the workpiece with grinding tools, according to different process purposes and requirements, there are various forms of grinding processing techniques. In order to meet the development needs, grinding technology is developing towards precision, low roughness, high efficiency, high speed and automatic grinding. There are many forms of grinding processing methods. In production, it mainly refers to grinding with a grinding wheel; most grinding machines use a high-speed rotating grinding wheel for grinding processing, and a few use other grinding tools such as oilstones and abrasive belts and free abrasives for processing, such as honing machines, superfinishing machines, abrasive belt grinding machines, grinding machines and polishing machines.
[0003] In order to achieve mechanized automatic processing, the current sheet processing process is mainly based on a production line. In the production line, the sheet is conveyed to each processing station for processing through a conveying device. When the sheet is subjected to grinding treatment, the sheet needs to be conveyed to the grinding station for grinding processing. During the conveying process of the sheet, due to its flat characteristics, when it is conveyed on a general conveying device, its position will change on the conveying device. Especially when the conveying rollers on the conveying device are made of hard materials, when they come into contact with the hard sheet, sliding is very likely to occur. In addition, even if the conveying rollers are replaced with materials such as rubber with a certain frictional force, due to different contacts and frictional forces, the conveying forces received by the sheet on the conveying rollers are also different, which makes the position of the sheet very likely to change during conveying. Even more so, during grinding, since the sheet is on the conveying device and it is difficult to fix the sheet to the conveying device, during the grinding process, the grinding wheel needs to apply a fixed-point pressure to the sheet to achieve a better grinding effect. Therefore, during grinding, the sheet needs to be relatively stable. Summary of the Invention
[0004] (I) Technical Problems to be Solved
[0005] Aiming at the deficiencies of the prior art, the present invention provides a grinding device for sheet processing, a grinding method and a sheet processing technology, which have the advantages that when the moving frame descends, the positioning frame is first docked with the positioning connection cylinder on the docking side arm (this docking process can use the prior art sensing docking, such as infrared detection docking, etc.), so that the bottom of the positioning frame extends into the positioning connection cylinder. At this time, under the pressing action of the moving frame, the positioning and pushing component is pressed on the sheet conveying mechanism, so that the sheet will not slide between the sheet conveying mechanism during grinding. This solves the problem that when the sheet is conveyed on a general conveying device, its position will change on the conveying device. Especially when the conveying rollers on the conveying device are made of hard materials, when contacting with the hard sheet, it is very easy to occur sliding phenomenon. In addition, even if the conveying rollers are replaced with materials with certain friction such as rubber, due to different contacts and frictions, the conveying forces received by the sheet on the conveying rollers are also different, so that the sheet is very easy to change its position during conveying. Even more, during grinding, since the sheet is on the conveying device and it is difficult to fix the sheet with the conveying device, and a certain pressure between the grinding wheel and the sheet is required to make the grinding effect better during grinding, so during grinding, a relatively stable sheet is more needed.

[0018] (III) Beneficial effects
[0019] Compared with the prior art, the present invention provides a grinding device, a grinding method and a plate processing technology for plate processing, which have the following beneficial effects:
[0020] 1. The plate processing grinding equipment straightens the plate conveyed forward by the straightening component in the plate straightening mechanism, so that the state of the plate is consistent with the conveying direction of the plate conveying mechanism, and then the straightened plate continues to be conveyed forward until one side of the far end of the plate contacts the positioning and pushing component, at which time the plate conveying mechanism stops conveying, and then the other end of the positioning and pushing component pushes the plate on the surface of the plate conveying mechanism to position and fix it, and then the plate conveying mechanism is started again. Driven by the plate conveying mechanism, the positioning and pushing component fixes the plate on the plate conveying mechanism, and the positioning and pushing component and the plate are moved together on the plate conveying mechanism. The plate is transported by the conveying mechanism to the direction of the positioning and grinding mechanism, so that the plate can be stably transported on the plate conveying mechanism, avoiding sliding between the plate and the plate conveying mechanism when using conventional conveying methods; when the plate is transported to the bottom of the positioning and grinding mechanism, the position is determined by the positioning frame and the positioning pushing assembly, so that the plate is located directly under the grinding assembly, and then the plate is ground by the grinding assembly; during processing, the positioning pushing assembly, with the cooperation of the positioning frame, fixes the plate and the plate conveying mechanism, avoiding sliding between the plate and the plate conveying mechanism during grinding.
[0021] 2. The plate processing grinding equipment straightens the plate being transported at the front end of the plate conveying mechanism through the straight channel in the straight component. When the plate enters the straight channel during the transportation process, if the plate is in an inclined state, one of its inclined sides contacts the straight channel, and in the state of continuing transportation, the plate is gradually straightened and transported between the straight rollers. In the initial stage, the straight roller first contacts one side of the plate, and as the plate is transported forward and under the action of the elastic compression member, the straight roller pushes the plate toward the middle until the pressures borne by the elastic compression members on both sides are the same, and the plate is transported forward at the middle part of the plate conveying mechanism; wherein the elastic compression member adopts a spring and sleeve structure, and the straight roller is connected to the end of the elastic compression member through a rotating base, so that after the straight roller contacts the plate, it can compress the elastic compression member and have a certain rolling correction effect at the same time.
[0022] 3. The plate processing grinding equipment, after the plate is positioned and fixed on the surface of the plate conveying mechanism by the other end of the positioning pushing component, the plate conveying mechanism is started again. Driven by the plate conveying mechanism, the positioning pushing component fixes the plate on the plate conveying mechanism, and the positioning pushing component and the plate are conveyed in the direction of the positioning grinding mechanism under the conveyance of the plate conveying mechanism, so that the plate can be stably conveyed on the plate conveying mechanism, avoiding sliding between the plate and the plate conveying mechanism when the conventional conveying method is adopted; wherein, the positioning clamp in the positioning pushing component is initially located at a position away from the end of the straightening component. When the plate passes through the straightening roller in the straightening component, it enters the front end of the positioning clamp, and the plate and the positioning clamp continue to be conveyed for a distance, and then the operation of the plate conveying mechanism is suspended. Then, the moving clamp in the positioning pushing component moves toward the positioning clamp under the pull of the pulling cable, and the two sides of the moving clamp are aligned with the docking side arms, so that the moving clamp cooperates with the positioning clamp to clamp the plate, wherein the positioning connecting tube corresponds to the center position of the plate after the clamping is completed.
[0023] 4. The grinding equipment for plate processing uses an elastic clamping plate arranged on the front side of the positioning clamping plate. The plate is pushed by the moving clamping plate to move toward the positioning clamping plate until the plate contacts the elastic clamping plate and continues to be conveyed forward to compress the elastic clamping plate. Then the push rod inside the elastic clamping plate moves toward the inside of the positioning clamping plate and pushes the expansion support rod inside the positioning clamping plate. In the state of the wedge-shaped components on both sides, the expansion support rod is moved toward both sides of the positioning clamping plate until the expansion support rod is extended into the conveying guide rails on both sides of the conveying frame. After the plate conveying mechanism is started again, when the positioning pushing component clamps the plate for conveying on the plate conveying mechanism, the expansion support rod is conveyed along the conveying guide rail to avoid tilting or horizontal movement when the positioning pushing component moves.
[0024] 5. The grinding equipment for plate processing is set in a tilted state through the front end of the sliding track. When the plate comes out of the straightening roller in the straightening component and enters from the bottom of the tilted sliding track, and the plate contacts the positioning clamp, the plate is first transported by the plate conveying mechanism, pushing the positioning clamp to move together until the docking side arm and the rack at the bottom of the sliding track enter the conveying roller shaft, and the rack is meshed with the conveying teeth on the conveying roller shaft. At this time, the operation of the plate conveying mechanism is suspended, and the winding shaft in the positioning pushing component is wound and pulled to move the moving clamp from the tilted part of the sliding track toward the positioning clamp, and the positioning clamp is used to clamp the plate. When the plate grinding process is completed, the positioning pushing component needs to release the clamping of the plate, the winding shaft unwinds and pulls the cable, and then under the tension of the reset spring set at the tilted end of the sliding track, the moving clamp returns to the tilted end of the sliding track again, so that the plate can be positioned and clamped next time.

Detailed implementation manners
[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0035] Please refer to Figure 1-8, a grinding device for sheet processing, comprising a sheet conveying mechanism 1, a sheet straightening mechanism 2, and a positioning and grinding mechanism 3. The sheet conveying mechanism 1 conveys a single sheet towards the positioning and grinding mechanism 3, and during the conveying process, the sheet passes through the sheet straightening mechanism 2 for straightening treatment. The sheet straightening mechanism 2 includes a straightening component 4 and a positioning and pushing component 5. The straightening component 4 is located above the sheet conveying mechanism 1, and the positioning and pushing component 5 is located at the end of the straightening component 4. The positioning and grinding mechanism 3 is located above the sheet conveying mechanism 1, and the positioning and grinding mechanism 3 includes a positioning frame 31 and a grinding component 32. The positioning frame 31 is located above the sheet conveying mechanism 1, and the grinding component 32 is located between the positioning frame 31 and the sheet conveying mechanism 1. When the positioning and pushing component 5 follows the sheet conveying mechanism 1 through the positioning and grinding mechanism 3, the sheet conveying mechanism 1 stops, and the positioning frame 31 is docked with the positioning and pushing component 5.
[0036] During use, place the sheet to be ground at the front end of the sheet conveying mechanism 1. The sheet is conveyed towards the processing station by the sheet conveying mechanism 1, so that the sheet passes through the sheet straightening mechanism 2. The straightening component 4 in the sheet straightening mechanism 2 straightens the sheet being conveyed forward, so that the state of the sheet is consistent with the conveying direction of the sheet conveying mechanism 1. Then the straightened sheet continues to be conveyed forward until one side of the distal end of the sheet contacts the positioning and pushing component 5. At this time, the sheet conveying mechanism 1 pauses the conveying. Then, the other end of the positioning and pushing component 5 is used to push the sheet to be positioned and fixed on the surface of the sheet conveying mechanism 1. After that, the sheet conveying mechanism 1 is started again. Driven by the sheet conveying mechanism 1, the positioning and pushing component 5 fixes the sheet on the sheet conveying mechanism 1, and the positioning and pushing component 5 and the sheet are conveyed towards the positioning and grinding mechanism 3 under the conveying of the sheet conveying mechanism 1, so that the sheet can be stably conveyed on the sheet conveying mechanism 1, avoiding the occurrence of sliding between the sheet and the sheet conveying mechanism 1 when using the conventional conveying method. When the sheet is conveyed below the positioning and grinding mechanism 3, the position is determined by the positioning frame 31 and the positioning and pushing component 5, so that the sheet is located directly below the grinding component 32. Then, the grinding component 32 performs grinding processing on the sheet. During the processing, due to the cooperation of the positioning and pushing component 5 with the positioning frame 31, the sheet is fixed between the sheet and the sheet conveying mechanism 1, avoiding the occurrence of sliding between the sheet and the sheet conveying mechanism 1 during the grinding process.
[0037] Further, the sheet conveying mechanism 1 includes a conveying frame 11. Conveying roller shafts 12 are provided on both side walls of the conveying frame 11. Support rollers 13 are provided at the other ends of the conveying roller shafts 12. Conveying teeth 14 are provided on the conveying roller shafts 12. The conveying roller shafts 12 provided on both side walls of the conveying frame 11 in the sheet conveying mechanism 1 drive the positioning and pushing assembly 5. At the same time, the support rollers 13 convey the sheet, enabling it to enter the straightening assembly 4 from the entrance of the sheet conveying mechanism 1 for straightening treatment. A conveyor belt for synchronous rotation of the conveying roller shafts 12 is provided on the side of the conveying frame 11. At the same time, a motor is used in cooperation with the belt drive mode to make the conveying roller shafts 12 on both sides rotate synchronously.
[0038] Further, the straightening assembly 4 includes a straightening channel 41, straightening rollers 42 and an elastic compression member 43. The straightening channel 41 is fixed above the conveying frame 11. The inner distance of the straightening channel 41 becomes shorter along the conveying direction of the sheet conveying mechanism 1. The straightening channel 41 is symmetrically arranged left and right. The straightening rollers 42 are located at the end of the straightening channel 41. The elastic compression member 43 is horizontally arranged above the sheet conveying mechanism 1. One end of the elastic compression member 43 is fixed above the conveying frame 11, and the other end of the elastic compression member 43 is connected to the straightening rollers 42. The straightening channel 41 in the straightening assembly 4 straightens the sheet being conveyed at the front end of the sheet conveying mechanism 1. When the sheet in the conveying process enters the straightening channel 41, if the sheet is in an inclined state, one of its inclined sides contacts the straightening channel 41, and in the continued conveying state, the sheet is gradually straightened and conveyed between the straightening rollers 42. At the initial stage, the straightening rollers 42 first contact one side of the sheet. As the sheet is conveyed forward and under the action of the elastic compression member 43, the straightening rollers 42 push the sheet towards the middle until the pressures borne by the elastic compression members 43 on both sides are the same, and the sheet is conveyed forward at the middle part on the sheet conveying mechanism 1. Among them, the elastic compression member 43 adopts a structure of a spring and a sleeve. The straightening rollers 42 are connected to the end of the elastic compression member 43 through a rotating base, so that after the straightening rollers 42 contact the sheet, they can compress the elastic compression member 43 and have a certain role in rolling correction at the same time.
[0039] Further, the positioning and pushing assembly 5 includes a positioning clamping plate 51, a moving clamping plate 52, a docking side arm 53, and a positioning connection cylinder 54. The positioning clamping plate 51 is arranged at the tail of the straightening assembly 4. The positioning clamping plate 51 is located above the conveying rack 11. The docking side arms 53 are installed on both sides of the positioning clamping plate 51. The moving clamping plate 52 is located at the other end of the docking side arms 53. A pulling cable 55 is arranged on the moving clamping plate 52. The positioning connection cylinder 54 is located above the docking side arms 53. In the initial state, the positioning clamping plate 51 in the positioning and pushing assembly 5 is located at a position far from the end of the straightening assembly 4. When the plate passes through the straightening rollers 42 in the straightening assembly 4 and enters the front end of the positioning clamping plate 51, and after the plate and the positioning clamping plate 51 continue to be conveyed for a certain distance together, the operation of the plate conveying mechanism 1 is paused. Then, the moving clamping plate 52 in the positioning and pushing assembly 5 moves towards the positioning clamping plate 51 under the pulling of the pulling cable 55, and the two sides of the moving clamping plate 52 are aligned with the docking side arms 53, so that the moving clamping plate 52 cooperates with the positioning clamping plate 51 to clamp the plate. After the clamping is completed, the positioning connection cylinder 54 corresponds to the center position of the plate.
[0040] Further, one end of the pulling cable 55 is located inside the docking side arm 53. A cable take-up reel 56 is arranged at the other end inside the docking side arm 53. The driving end of the cable take-up reel 56 is connected to the pulling cable 55. A sliding track 57 is arranged on the side of the docking side arm 53. Both ends of the moving clamping plate 52 are slidably connected to the sliding track 57. By winding the pulling cable 55 by the cable take-up reel 56 arranged at one end of the pulling cable 55, the moving clamping plate 52 at the other end of the pulling cable 55 can move towards the positioning clamping plate 51. When the moving clamping plate 52 moves, it moves along the sliding track 57, and thus the plate is clamped between the moving clamping plate 52 and the positioning clamping plate 51. The cable take-up reel 56 uses an existing steel cable winding mechanism to wind the pulling cable 55, which will not be elaborated here.
[0041] Further, the docking side arm 53 is fixedly connected to the sliding track 57. A rack 58 is arranged at the bottom of the docking side arm 53 and the sliding track 57. The rack 58 is meshed with the conveying teeth 14; through the rack 58 arranged at the bottom of the docking side arm 53 and the sliding track 57, which cooperates with the conveying teeth 14 on the conveying roller shaft 12, after the moving clamping plate 52 and the positioning clamping plate 51 clamp and fix the plate, the positioning and pushing assembly 5 can be conveyed synchronously with the plate on the plate conveying mechanism 1.
[0042] Furthermore, an elastic clamping plate 511 is provided on the front surface of the positioning clamping plate 51. The elastic clamping plate 511 contacts the side surface of the plate. A push rod 512 is provided on the back surface of the elastic clamping plate 511. The push rod 512 extends into the positioning clamping plate 51. An expansion support rod 513 is provided inside the positioning clamping plate 51. The expansion support rod 513 extends towards both ends outside the positioning clamping plate 51. The push rod 512 and the expansion support rod 513 are directly connected by a wedge-shaped member. Conveyor guide rails 15 are provided on both side walls of the conveyor frame 11. The expansion support rod 513 extends outwards into the conveyor guide rails 15. The expansion support rod 513 is in sliding fit with the conveyor guide rails 15; through the elastic clamping plate 511 provided on the front surface of the positioning clamping plate 51, the plate moves towards the positioning clamping plate 51 under the push of the moving clamping plate 52 until it contacts the elastic clamping plate 511 and then continues to be conveyed forward, compressing the elastic clamping plate 511. Then, the push rod 512 inside the elastic clamping plate 511 moves into the positioning clamping plate 51 and pushes the expansion support rod 513 inside the positioning clamping plate 51. In the state of the wedge-shaped members on both sides, the expansion support rod 513 moves towards both sides of the positioning clamping plate 51 until the expansion support rod 513 extends into the conveyor guide rails 15 on both sides of the conveyor frame 11. When the plate conveying mechanism 1 is started again and the positioning and pushing assembly 5 clamps the plate and conveys it on the plate conveying mechanism 1, the expansion support rod 513 is conveyed along the direction of the conveyor guide rails 15, preventing the positioning and pushing assembly 5 from tilting or moving horizontally when moving.
[0043] Furthermore, the front end of the sliding track 57 is upturned. A return spring 59 is provided between the moving clamping plate 52 and the sliding track 57. The return spring 59 is in a compressed state. One end of the return spring 59 is fixed to the upturned end of the sliding track 57; by setting the front end of the sliding track 57 in an upturned state, when the plate comes out from the straightening rollers 42 in the straightening assembly 4 and enters from the bottom of the upturned sliding track 57 and contacts the positioning clamping plate 51, the plate is first conveyed by the plate conveying mechanism 1 and pushes the positioning clamping plate 51 to move together until the rack 58 at the docking side arm 53 and the bottom of the sliding track 57 enters the conveying roller shaft 12. At this time, the operation of the plate conveying mechanism 1 is paused. The take-up reel 56 in the positioning and pushing assembly 5 winds up and pulls the cable 55, causing the moving clamping plate 52 to move from the upturned part of the sliding track 57 towards the positioning clamping plate 51 and cooperating with the positioning clamping plate 51 to clamp the plate. When the grinding process of the plate is completed and the positioning and pushing assembly 5 needs to release the clamping of the plate, the take-up reel 56 unwinds and pulls the cable 55. Then, under the pulling force of the return spring 59 provided at the upturned end of the sliding track 57, the moving clamping plate 52 returns to the upturned end of the sliding track 57 again for the next positioning and clamping of the plate.
[0044] Furthermore, the grinding assembly 32 includes a grinding wheel 34, a CNC grinding system and a movable frame 35. The movable frame 35 is located above the positioning frame 31, and the grinding wheel 34 is located on the movable frame 35. The CNC grinding system is used to control the operation of the grinding wheel 34. The grinding wheel 34 is controlled by the CNC grinding system in the grinding assembly 32 to grind the plate at the bottom of the movable frame 35. When in use, the movable frame 35 moves downward, and firstly the positioning frame 31 is docked with the positioning connecting tube 54 on the docking side arm 53 (the docking process can adopt the existing technology of induction docking, such as: infrared detection docking, etc.), so that the bottom of the positioning frame 31 extends into the positioning connecting tube 54. At this time, under the downward pressure of the movable frame 35, the positioning pushing assembly 5 is pressed on the plate conveying mechanism 1, so that the plate will not slide between the plate conveying mechanism 1 during grinding.
[0045] A grinding method uses a grinding device for plate processing.
[0046] Working principle: When in use, the plate to be ground is placed at the front end of the plate conveying mechanism 1, and the plate is conveyed to the processing station through the plate conveying mechanism 1, so that the plate passes through the plate straightening mechanism 2, and the positioning and pushing component 5 is driven by the conveying rollers 12 arranged on the two side walls of the conveying frame 11 in the plate conveying mechanism 1, and the conveying belt that rotates synchronously with the conveying rollers 12 arranged on the side of the conveying frame 11 is adopted. At the same time, the motor cooperates with the belt transmission method to make the conveying rollers 12 on both sides rotate synchronously, and then the plate is conveyed by the support rollers 13, so that it enters the straightening component 4 from the entrance of the plate conveying mechanism 1 for correction processing;
[0047] Then the straightening component 4 in the plate straightening mechanism 2 straightens the plate being transported forward, so that the state of the plate is consistent with the transport direction of the plate transporting mechanism 1, and then the straightened plate continues to be transported forward until one side of the far end of the plate contacts the positioning and pushing component 5; the plate being transported at the front end of the plate transporting mechanism 1 is straightened through the straightening channel 41 in the straightening component 4, and when the plate in the transport process enters the straightening channel 41, if the plate is in an inclined state, one of its inclined sides contacts the straightening channel 41, and in the state of continuing to be transported, the plate is gradually straightened and transported to the straightening roller The straight roller 42 is between the wheels 42. In the initial stage, the straight roller 42 first contacts one side of the plate, and as the plate is transported forward, under the action of the elastic compression member 43, the straight roller 42 pushes the plate toward the middle until the pressures borne by the elastic compression members 43 on both sides are the same, and the plate is transported forward at the middle part of the plate conveying mechanism 1; wherein the elastic compression member 43 adopts a spring and sleeve structure, and the straight roller 42 is connected to the end of the elastic compression member 43 through a rotating base, so that after the straight roller 42 contacts the plate, it can compress the elastic compression member 43 and have a certain rolling correction effect;
[0048] At this time, the sheet conveying mechanism 1 pauses conveying. Then, the other end of the positioning and pushing component 5 pushes the sheet to be positioned and fixed on the surface of the sheet conveying mechanism 1. After that, the sheet conveying mechanism 1 is restarted. Driven by the sheet conveying mechanism 1, the positioning and pushing component 5 fixes the sheet on the sheet conveying mechanism 1. And the positioning and pushing component 5 and the sheet are conveyed towards the positioning and grinding mechanism 3 under the conveyance of the sheet conveying mechanism 1, so that the sheet can be stably conveyed on the sheet conveying mechanism 1, avoiding sliding between the sheet and the sheet conveying mechanism 1 when using the conventional conveying method. Among them, the positioning clamping plate 51 in the positioning and pushing component 5 is initially located at a position far from the end of the straightening component 4. When the sheet passes through the straightening roller 42 in the straightening component 4 and enters the front end of the positioning clamping plate 51, and the sheet and the positioning clamping plate 51 continue to be conveyed for a certain distance, the operation of the sheet conveying mechanism 1 is paused. Then, the moving clamping plate 52 in the positioning and pushing component 5 moves towards the positioning clamping plate 51 under the pulling of the pulling cable 55, and aligns the two sides of the moving clamping plate 52 with the docking side arms 53, so that the moving clamping plate 52 cooperates with the positioning clamping plate 51 to clamp the sheet. After clamping, the positioning connection cylinder 54 corresponds to the center position of the sheet.
[0049] In the above process, by winding the pulling cable 55 through the winding shaft 56 provided at one end of the pulling cable 55, the moving clamping plate 52 at the other end of the pulling cable 55 can move towards the positioning clamping plate 51. When the moving clamping plate 52 moves, it moves along the sliding track 57, and then clamps the sheet between the moving clamping plate 52 and the positioning clamping plate 51. The docking side arms 53 and the rack 58 provided at the bottom of the sliding track 57 cooperate with the conveying teeth 14 on the conveying roller shaft 12, so that after the moving clamping plate 52 and the positioning clamping plate 51 clamp and fix the sheet, the positioning and pushing component 5 can be conveyed synchronously with the sheet on the sheet conveying mechanism 1.
[0050] The elastic clamping plate 511 provided on the front surface of the positioning clamping plate 51. The sheet moves towards the positioning clamping plate 51 under the push of the moving clamping plate 52 until it contacts the elastic clamping plate 511 and continues to be conveyed forward, compressing the elastic clamping plate 511. Then, the push rod 512 inside the elastic clamping plate 511 moves towards the inside of the positioning clamping plate 51 and pushes the expansion support rod 513 inside the positioning clamping plate 51. In the state of the wedge-shaped members on both sides of it, the expansion support rod 513 moves towards both sides of the positioning clamping plate 51 until the expansion support rod 513 extends into the conveying guide rails 15 on both sides of the conveying frame 11. After the sheet conveying mechanism 1 is restarted again, when the positioning and pushing component 5 clamps the sheet and is conveyed on the sheet conveying mechanism 1, the expansion support rod 513 is conveyed along the direction of the conveying guide rail 15, avoiding tilting or horizontal movement when the positioning and pushing component 5 moves.
[0051] The front end of the sliding track 57 is set in a tilted state. When the sheet comes out of the straightening roller 42 in the straightening component 4, it enters from the bottom of the tilted sliding track 57 and makes the sheet contact with the positioning clamping plate 51. The sheet first pushes the positioning clamping plate 51 to move together under the conveyance of the sheet conveying mechanism 1 until the docking side arm 53 and the rack 58 at the bottom of the sliding track 57 enter the conveying roller shaft 12, and the rack 58 meshes with the conveying teeth 14 on the conveying roller shaft 12. At this time, the operation of the sheet conveying mechanism 1 is suspended, and the positioning clamping plate 51 is used to move the sheet. The reel 56 in the push assembly 5 reels and pulls the cable 55, so that the movable clamping plate 52 moves from the tilted part of the sliding track 57 to the direction of the positioning clamping plate 51, and cooperates with the positioning clamping plate 51 to clamp the plate. When the plate grinding process is completed, the positioning push assembly 5 needs to release the clamping of the plate, and the reel 56 unwinds and pulls the cable 55. Then, under the tension of the reset spring 59 set at the tilted end of the sliding track 57, the movable clamping plate 52 returns to the tilted end of the sliding track 57 again, so as to position and clamp the plate next time.
[0052] When the plate is transported to the bottom of the positioning and grinding mechanism 3, the position is determined by the positioning frame 31 and the positioning pushing assembly 5, so that the plate is located directly below the grinding assembly 32, and then the grinding assembly 32 performs grinding processing on the plate; the CNC grinding system in the grinding assembly 32 controls the grinding wheel 34 to grind the plate at the bottom of the movable frame 35. When in use, the movable frame 35 moves downward, and firstly the positioning frame 31 is docked with the positioning connecting tube 54 on the docking side arm 53 (the docking process can adopt the existing technology of induction docking, such as infrared detection docking, etc.), so that the bottom of the positioning frame 31 extends into the positioning connecting tube 54. At this time, under the downward pressure of the movable frame 35, the positioning pushing assembly 5 is pressed on the plate conveying mechanism 1, so that the plate will not slide between the plate conveying mechanism 1 during grinding.
