[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0032] Example 1, referring to Figures 1-5This is the first embodiment of the present invention, which provides a metal sheet processing machine tool, which includes a grinding machine tool 1 and a fixing mechanism 2.

[0033] Specifically, the grinding machine tool 1 includes a vertical plate 11 and a sanding belt 12 for grinding metal sheets. The sanding belt 12 is located on one side of the vertical plate 11. The specifications of the sanding belt 12 can be selected according to the grinding requirements of the metal sheets to meet the grinding requirements. The sanding belt 12 adopts a ring-shaped closed structure and is sleeved on the outside of the transmission adjustment component 13.

[0034] Specifically, the transmission adjustment component 13 is installed on one side of the vertical plate 11 and cooperates with the sanding belt 12 to realize the transmission of the sanding belt 12. It can also adjust the shape of the sanding belt 12 according to the shape of the metal plate to be ground, so that the sanding belt 12 can meet the grinding of straight plates and curved plates. The transmission adjustment component 13 maintains the tension of the sanding belt 12. When grinding straight metal plates, the bottom surface of the outer side of the sanding belt 12 is flat and fully fits the contact surface with the straight metal plate, ensuring the flatness of the ground surface. When grinding curved metal plates, according to the radius of curvature of the curved plate, as the sanding belt 12 moves down to contact the plate, under the support of the transmission adjustment component 13, the bottom of the outer side surface forms a corresponding arc shape, fully fitting the outer surface of the curved metal plate. At the same time, it compensates for the length deviation of the sanding belt 12 caused by the shape change, keeps the tension stable, and ensures that the contact pressure between the sanding belt 12 and the workpiece is uniform during the grinding of curved plates.

[0035] Specifically, the applicator 14 is installed on the transmission adjustment component 13 and the vertical plate 11, and cooperates with the transmission adjustment component 13. It is used to apply a thin layer of polishing paste to metal plates with special grinding and polishing requirements. The applicator 14 can not only apply polishing paste, but also replace the polishing paste in the paste box 141 with other application auxiliary materials to meet the grinding operation. For example, when grinding metal for fine grinding / difficult-to-machine materials: apply cooling and lubricating materials to prevent burns and blockages. When grinding soft metals: apply anti-stick materials to extend the life of the sanding belt 12.

[0036] Specifically, the movable seat 15 is located below the sanding belt 12 and has several through holes arranged in a linear array on the movable seat 15.

[0037] Specifically, the fixing mechanism 2 is installed on the movable seat 15 and the transmission adjustment component 13, and is used to fix and unlock the metal plate.

[0038] The fixing component 21 is fixed to the inner cavity of the through hole on the movable seat 15 by the support rod. It is used to fix and unlock the metal plate. There are several fixing components 21, and the number is the same as the number of through holes. After the plate is placed on it, the metal plate can be initially fixed by the fixing component 21, and the operator can manually adjust it. After the sanding belt 12 is pressed onto the plate by the transmission adjustment component 13, it can be reinforced again to prevent movement during the sanding process.

[0039] The power-on / off component 22, installed on the transmission adjustment component 13, is used to enable the power-on and power-off operation of the fixing component 21. With the power-on / off component 22, after the sanding belt 12 moves down and presses onto the sheet metal, the power-on / off component 22, driven by the transmission adjustment component 13, energizes the fixing component 21, generating electromagnetic attraction to reinforce the metal sheet. After grinding, when the sanding belt moves up, the power supply line is disconnected, and the electromagnetic attraction of the fixing component 21 disappears. At this point, the operator can directly pick up the ground metal sheet. Automatic power-on / off is achieved through the linkage with the stroke of the transmission adjustment component 13. The structure is simple and highly reliable; the linkage process is synchronized with the pressing and resetting actions of the sanding belt 12, eliminating the need for manual control by the operator and improving grinding efficiency; the electromagnetic attraction fixing method is adaptable to metal sheets of different shapes (straight / curved), providing strong fixing stability.

[0040] Example 2, refer to Figures 2-8 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0041] Specifically, the grinding machine tool 1 also includes a base 16 set on the worktable. A Y-axis moving module 17 for moving the movable seat 15 and the fixed member 21 along the Y-axis is installed on the base 16. An X-axis moving module 18 for moving the movable seat 15 and the fixed member 21 along the X-axis is installed on the Y-axis moving module 17, and the movable seat 15 is installed on the X-axis moving module 18. A Z-axis moving module 19 for moving the vertical plate 11 along the Z-axis is installed on the base 16, and the vertical plate 11 is installed on the Z-axis moving module 19.

[0042] The Y-axis moving module 17, X-axis moving module 18, and Z-axis moving module 19 all adopt a dual-guide rail lead screw transmission structure, which is existing technology. The working principle of this part is also existing technology, which can be clearly understood by those skilled in the art, and will not be described in detail here. The moving seat 15 is installed on the slider of the X-axis moving module 18, and the fixing part 21 is integrated and installed on the moving seat 15 to support and fix the metal plate. The X-axis and Y-axis modules cooperate to realize the adjustment of the metal plate at any position on the horizontal plane, which can meet the grinding and positioning requirements of plates of different sizes. Through the setting of the Z-axis moving module 19, when the driving vertical plate 11 and the transmission adjustment part 13 on it move down, the sanding belt 12 moves down to contact the plate, triggering the on / off element 22 to energize the fixing part 21; when the sanding belt 12 moves up to reset, the on / off element 22 triggers the power off, realizing the linkage control of "movement-on / off-grinding".

[0043] Specifically, the transmission adjustment component 13 includes two movable plates 131 that rotate on one side of the vertical plate 11. Each of the two movable plates 131 has a side roller 132 rotating at its lower end, and the side roller 132 cooperates with the sanding belt 12. The side roller 132 is rotatably connected to the movable plate 131 through a bearing. A vertical cylinder 133 is fixed on one side of the vertical plate 11 through a support rod. A vertical rod 134 slides on the vertical cylinder 133. A pressure roller 135 rotates at the lower end of the vertical rod 134, and the pressure roller 135 cooperates with the sanding belt 12. The pressure roller 135 is rotatably connected to the vertical rod 134 through a bearing. A piston 136 is fixedly sleeved on the vertical rod 134, and the piston 136 slides on the inner wall of the vertical cylinder 133. A spring 137 is sleeved on the surface of the vertical rod 134, and the two ends of the spring 137 are respectively fixed to the bottom of the piston 136 and the inner wall of the vertical cylinder 133.

[0044] Short blocks 138 are symmetrically distributed and fixed on one side of the vertical plate 11. An arc-shaped rod 139 is fixed between the two short blocks 138. Two movable plates 131 are slidably sleeved on the arc-shaped rod 139. Springs 1310 are sleeved at both ends of the arc-shaped rod 139. The two ends of the springs 1310 are fixed to the bottom of the short blocks 138 and the surface of the movable plates 131, respectively. Springs 1311 are sleeved in the middle section of the arc-shaped rod 139. The two ends of the springs 1311 are fixed between the two movable plates 131. A motor 1312 is fixed on one side of the vertical plate 11. A transmission disc 1313 is fixed to the output shaft of the motor 1312. The sanding belt 12 is driven and sleeved on the surface of the transmission disc 1313 and the side roller 132.

[0045] The transmission adjustment component 13 is based on the movable plate 131, side rollers 132, vertical cylinder 133, and pressure roller 135, and works with the arc rod 139 and multiple sets of springs to realize the transmission support and adaptive adjustment of the shape of the sanding belt 12. The two side rollers 132 at the lower end provide support points on both sides of the sanding belt 12. The vertical rod 134 drives the pressure roller 135 to slide up and down along the vertical cylinder 133. The pressure roller 135 abuts against the middle of the inner side of the sanding belt 12, forming a three-point support structure of "support on both sides + pressure in the middle", which ensures the stability of the sanding belt 12 during operation.

[0046] The piston 136 slides against the inner wall of the vertical cylinder 133 to prevent the vertical rod 134 from skewing when sliding. The elastic restoring force of the spring 137 is transmitted to the vertical rod 134 through the piston 136, so that the pressure roller 135 always maintains the holding force on the sanding belt 12, compensating for the loosening of the sanding belt 12 due to wear and avoiding slippage. The center of the arc rod 139 is the same as the rotation center of the movable plate 131. When the sanding belt 12 moves down and presses against the plate, the movable plate 131 can rotate along the trajectory of the arc rod 139, thereby driving the side roller 132 to adjust its position and change the shape of the sanding belt 12.

[0047] There are two springs 1310. The elastic force of the springs 1310 can limit the excessive sliding of the movable plate 131 and prevent the side roller 132 from detaching from the sanding belt 12. The spring 1311 is located between the two movable plates 131 and can realize the automatic reset of the movable plates 131: when sanding a straight plate, the sanding belt 12 is pushed by the reaction force of the plate to push the side roller 132, causing the two movable plates 131 to slide to both sides along the arc rod 139 and stretch the spring 1311; when the sanding is completed, the spring 1311... The elastic restoring force drives the movable plate 131 to reset, so that the sanding belt 12 returns to its initial state. The surface of the transmission disc 1313 is processed with anti-slip teeth to increase the friction with the sanding belt 12 and ensure stable power transmission. The surface of the side roller 132 is treated with smooth chrome plating to reduce friction loss with the sanding belt 12. When the motor 1312 drives the transmission disc 1313 to rotate, it drives the sanding belt 12 to rotate around the transmission disc 1313 and the side roller 132. With the holding force of the pressure roller 135, the metal sheet is polished.

[0048] When grinding straight metal sheets, as the sanding belt 12 moves downward, the side rollers 132 and pressure rollers 135 contact the straight metal sheet with the help of the sanding belt 12. As the belt moves downward, the opening angle between the two movable plates 131 increases, and at the same time, the vertical rod 134 moves on the vertical cylinder 133. The two side rollers 132 and the pressure roller 135 together support the sanding belt 12 to a flat state, ensuring that the sanding belt 12 is completely in contact with the surface of the straight sheet. When grinding curved metal sheets, the curved sheet pushes the sanding belt 12 to deform inward, and the sanding belt 12 drives the side rollers 132 to move towards the center. The movable plate 131 slides along the curved rod 139 and compresses the spring 1311. At this time, the sanding belt 12 adjusts with the position of the side rollers 132 to form an arc shape that matches the curvature of the curved sheet. The pressure roller 135 maintains the holding force on the sanding belt 12 under the action of the spring 137, ensuring that the sanding belt 12 is in close contact with the surface of the curved sheet.

[0049] Specifically, the applicator 14 includes a paste box 141 fixed on the vertical plate 11, a bend 142 connecting the paste box 141 and the vertical cylinder 133, a three-way valve 144 fixed on one side of the vertical plate 11 by a support, a bend 2 143 connecting the vertical cylinder 133 and the three-way valve 144, a bend 3 145 connecting the three-way valve 144, and a paste outlet 146 connecting the end of the bend 3 145 away from the three-way valve 144, with a paste outlet hole 147 on the paste outlet 146, a bend 4 148 connecting the three-way valve 144 and the paste box 141, and a one-way valve 149 and a one-way valve 2 1410 respectively installed at the ends of the bend 142 and the bend 2 143 near the vertical cylinder 133.

[0050] The coating component 14 uses the reciprocating motion of the piston 136 inside the vertical cylinder 133 as its core power source. It works in conjunction with multiple sets of bends, one-way valves, and three-way valves 144 to achieve quantitative delivery and circulation of the paste. The piston 136 and the vertical rod 134 are sealed with the cylinder 211. One-way valve 149 only allows paste to flow from the paste tank 141 into the vertical cylinder 133, and one-way valve 1410 only allows paste to flow from the vertical cylinder 133 into the three-way valve 144 to prevent backflow of the paste and ensure that the delivery direction is controllable. The opening and rotation of the three-way valve 144 can only be 90 degrees back and forth. When the grinding conditions require quantitative delivery of the paste, the three-way valve 144 is rotated to keep the bend 143 and the bend 145 connected. When the transmission adjustment component 13 drives the vertical rod 134 to move up and down, the piston 136 reciprocates with the vertical rod 134 inside the vertical cylinder 133, and the automatic delivery of the paste is achieved by using the pressure difference.

[0051] Material suction stage: The vertical rod 134 drives the piston 136 to move down inside the vertical cylinder 133, and a negative pressure is formed in the upper space of the vertical cylinder 133. One-way valve 2 1410 is closed and one-way valve 149 is opened. The paste in the paste box 141 flows into the upper part of the vertical cylinder 133 through the bend pipe 142 under atmospheric pressure.

[0052] Pressing stage: The vertical rod 134 drives the piston 136 to move upward in the vertical cylinder 133, the pressure in the upper space of the vertical cylinder 133 increases, the one-way valve 149 closes and the one-way valve 2 1410 opens, the paste is pressed into the three-way valve 144 through the second bend 143, and then squeezed out from the paste outlet hole 147 of the paste outlet head 146 through the third bend 145 to achieve quantitative coating. The stroke of the piston 136 is controlled by the displacement of the pressure roller 135 of the transmission adjustment component 13 relative to the vertical cylinder 133, and is controlled according to the downward grinding force.

[0053] When the grinding conditions do not require the delivery of paste, turn the three-way valve 144 to keep the second bend 143 and the fourth bend 148 connected, and return the paste to the paste tank 141. This can be used for equipment debugging or paste circulation to prevent curing. The paste outlet 146 is made of wear-resistant hard alloy material and is 0.1mm away from the surface of the sanding belt 12. The paste outlet hole 147 is a micron-sized circular hole and is perpendicular to the running direction of the sanding belt 12 to ensure uniform paste coating.

[0054] Example 3, referring to Figures 1-6 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0055] Specifically, the fixing component 21 includes a cylindrical body 211 fixed to the inner cavity of the through hole by a support rod. An electromagnet 212 is embedded in the upper end of the cylindrical body 211. A rubber ring 213 for cleaning and protecting the electromagnet 212 is provided on the cylindrical body 211. Elastic strips 214 arranged in a circumferential array are embedded inside the rubber ring 213. A support plate 215 is fixed to the inner wall of the cylindrical body 211. A spline rod 216 slides on the support plate 215. The rubber ring 213 is sleeved on the surface of the spline rod 216. A permanent magnet 217 that cooperates with the metal plate is fixed at the upper end of the spline rod 216. A pressure block 218 is slidably sleeved on the spline rod 216. The lower end of the rubber ring 213 is fixed to the top of the pressure block 218. A spring 219 is sleeved on the surface of the spline rod 216. The two ends of the spring 219 abut against the bottom of the pressure block 218 and are fixed to the top of the support plate 215, respectively.

[0056] The fastener 21 is based on the dual magnetic cooperation of electromagnet 212 and permanent magnet 217, and is protected by rubber ring 213. It can firmly fix the metal plate and automatically clean and protect the electromagnet 212. The electromagnet 212 is embedded in the groove at the upper end of the cylinder 211 and is connected to the power supply line of the on / off component 22. When energized, it generates a strong electromagnetic attraction. The permanent magnet 217 is located directly above the electromagnet 212 and can slide up and down with the spline rod 216 to form a magnetic attraction superposition effect with the electromagnet 212, which enhances the fixing force.

[0057] A fixing ring 2110 is fixed to the outer surface of the cylinder 211. A circular array of rods 2111 slides on the fixing ring 2110. A scraper ring 2112 is fixed to the upper end of each rod 2111, and a ring body 2113 is fixed to the lower end of each rod 2111. A rotating cylinder 2114 rotates at the lower end of the cylinder 211. A circular block 2115 is fixed to the lower end of a splined rod 216, and the circular block 2115 slides on the inner wall of the rotating cylinder 2114. A guide groove 2116 is provided, and a ball bearing 2117 is embedded in the round block 2115. The ball bearing 2117 slides in the guide groove 2116. A spring 2118 abuts between the bottom of the round block 2115 and the inner wall of the rotating cylinder 2114. The spring 2118 is located in the inner cavity of the rotating cylinder 2114. A connecting rope 2119 passes through the rotating cylinder 2114, and the two ends of the connecting rope 2119 are respectively fixed to the bottom of the ring 2113 and the surface of the rotating cylinder 2114.

[0058] The rubber ring 213 is a trumpet-shaped annular elastic structure. The elastic strip 214 is made of polyurethane and is distributed in a circumferential array to enhance the elastic recovery force of the rubber ring 213 and prevent the rubber ring 213 from deforming due to long-term compression. The edges of the rubber ring 213 and the scraper ring 2112 are rounded to prevent damage during contact and movement. The rounded edges can prevent the sharp corners of the scraper ring 2112 from wearing down the rubber ring 213. The guide groove 2116 is divided into three parts. The first and third parts are where the ball bearings 2117 do not cause the rotating drum 2114 to rotate when they move inside. The second part is where the ball bearings 2117 can cause the rotating drum 2114 to rotate when they move inside. The rotating drum 2114 is rotatably connected to the cylinder 211 through the bearing. The round rod 2111 passes through the fixed ring 2110 and is slidably connected to it.

[0059] A stop block 2120 is fixedly sleeved on the upper surface of the spline rod 216, and the stop block 2120 cooperates with the pressure block 218. A spring piece 2121 is fixed between the bottom of the scraper ring 2112 and the top of the fixing ring 2110.

[0060] When the metal plate is placed on the movable seat 15, the plate presses down on the permanent magnet 217, which drives the spline rod 216 and the abutment 2120 and round block 2115 to move down. This causes the ball bearing 2117 to move from the first part of the guide groove 2116 through the second part and into the third part, causing the rotating drum 2114 to rotate and stop. The spring 2118 is also compressed. When the rotating drum 2114 rotates, it pulls the connecting rope 2119 to move the ring body 2113 downward. The ring body 2113 drives the scraper ring 2112 downward through the round rod 2111, so that the scraper ring 2112 cleans the impurities attached to the outer surface of the rubber ring 213 on the surface of the electromagnet 212 that was cleaned last time.

[0061] As the stop block 2120 moves down and contacts the pressure block 218, the spline rod 216 continues to move down, causing the pressure block 218 to move down as well. This moves the rubber ring 213 into the cylinder 211, exposing the electromagnet 212. At the same time, the spring 219 is compressed, and the bottom of the metal plate contacts the top of the electromagnet 212. Then, the subsequent on / off switch 22 is energized and magnetically fixes the metal plate. When the plate is polished, the electromagnet 212 is de-energized. When the plate is removed, the elastic restoring force of the spring 219 pushes the pressure block 218 up. The pressure block 218 causes the upper surface of the rubber ring 213 to adhere to the surface of the electromagnet 212. The elastic friction of the rubber ring 213 cleans the metal debris on the surface of the electromagnet 212, achieving a "clean upon removal" linkage effect.

[0062] When the plate is placed and fixed, the pressure block 218 moves down, and the rubber ring 213 is in a stretched state, with its upper end face flush with the surface of the electromagnet 212, which does not affect the contact between the plate and the electromagnet 212. When the plate is removed, the pressure block 218 moves up, and the rubber ring 213 contracts and presses tightly against the surface of the electromagnet 212. The elastic force of the elastic strip 214 causes the rubber ring 213 to rub against the surface of the electromagnet 212, scraping away the metal debris remaining during the polishing process and preventing the debris from affecting the magnetic attraction effect of the electromagnet 212. At the same time, the rubber ring 213 can prevent the plate from colliding with the surface of the electromagnet 212 when it is placed directly, playing a protective role and extending the service life of the electromagnet 212. During the process of removing and resetting the plate, the scraper ring 2112 can clean the rubber ring 213 again.

[0063] During the plate grinding stage, the abutment block 2120 and the pressure block 218 remain in contact, the rubber ring 213 is in a stretched state, and the scraper ring 2112 remains in a downward state, ensuring that the plate and the surface of the electromagnet 212 are in close contact, and grinding is performed without interference from the cleaning structure.

[0064] With the setting of the spring piece 2121, the round rod 2111 drives the scraper ring 2112 to move down, and the spring piece 2121 is compressed and deformed. At this time, the elastic restoring force of the spring piece 2121 is stored inside, providing power for the reset of the scraper ring 2112 and for secondary cleaning pressure compensation. The cylinder 211 is provided with a moving hole for the movement of the connecting rope 2119, and the corners are rounded and smoothed. The connecting rope 2119 is a steel wire rope to prevent the connecting rope 2119 from rubbing against the edge of the moving hole and breaking.

[0065] Specifically, the switching device 22 includes a trigger plate 221 fixed to the upper end of the vertical rod 134. The trigger plate 221 has a guide hole 222. Two square rods 223 are symmetrically fixed on the surface of the vertical cylinder 133. A block 1 224 and a block 225 are slidably sleeved on the square rods 223 respectively. A limit block 226 is fixed to one end of the square rod 223. A spring piece 227 is fixed between the surface of the limit block 226 and the surface of the block 1 224. A conductive ring 1 228 and a conductive ring 229 are fixed on the opposite side of the block 1 224 and the block 2 225 respectively. The conductive ring 1 228 and the conductive ring 229 cooperate with each other. A sliding column 2210 is fixed on the opposite side of the two blocks 1 224. The sliding column 2210 slides in the guide hole 222. The conductive ring 229 is electrically connected to the electromagnet 212 through a wire.

[0066] The guide hole 222 is divided into three parts. The first and third parts prevent the block 224 from moving when the sliding column 2210 moves inside it. The second part allows the block 224 to move when the sliding column 2210 moves inside it. Through the cooperation between the guide hole 222 of the trigger plate 221 and the sliding column 2210, the linear motion of the vertical rod 134 is converted into the horizontal sliding of the block 224, thereby realizing the contact and separation of the conductive ring 228 and the conductive ring 229. Both the conductive ring 228 and the conductive ring 229 are annular copper conductive sheets with silver plating to enhance conductivity and oxidation resistance. The conductive ring 229 is connected to the electromagnet 212 through a wire, and the conductive ring 228 is connected to an external power source through a wire. When the two are in contact, a closed circuit is formed.

[0067] When the Z-axis moving module 19 drives the vertical plate 11 to move downward, the sanding belt 12 moves closer to the metal plate. At the same time, the vertical rod 134 moves downward with the sanding belt 12, and the trigger plate 221 moves downward synchronously. After the sanding belt 12 contacts the plate, as it moves downward, the vertical rod 134 moves upward relative to the vertical cylinder 133, causing the sliding column 2210 to enter the third part from the first part of the guide hole 222 through the second part, driving the two blocks 1 224 to slide along the square rod 223 towards the direction of block 225. When the sanding belt 12 contacts the plate... When the material surface contacts and generates a preset holding force, the conductive ring 228 on block 224 and the conductive ring 229 on block 225 are in close contact, the spring 227 is compressed, the circuit is completed, the electromagnet 212 is energized to generate electromagnetic attraction to fix the plate. After grinding, the Z-axis moving module 19 drives the vertical plate 11 to move upward, the conductive ring 228 and the conductive ring 229 are separated, the circuit is broken, the electromagnet 212 is de-energized, the electromagnetic attraction disappears, and it is convenient for the operator to pick up the part.

[0068] A detachable and fixed cover 110 is installed on one side of the vertical plate 11 to cover its internal structure and provide protection.

[0069] In use, it adapts to multiple grinding modes: the motor 1312 drives the transmission disc 1313 to rotate the sanding belt 12. When grinding straight plates, the sanding belt 12 remains flat under the support of the side roller 132 and the pressure roller 135, and is completely in contact with the plate. When grinding curved plates, the plate pushes the sanding belt 12 to deform, the side roller 132 slides along the curved rod 139, and the pressure roller 135 maintains the holding force under the action of the spring. The sanding belt 12 adapts to form the corresponding arc shape to ensure uniform grinding.

[0070] Automatic fixing and unlocking: The metal sheet is placed on the moving seat 15. The permanent magnet 217 is pressed down, which drives the spline rod 216 to move down. The scraper ring 2112 cleans the rubber ring 213 at the same time. The pressure block 218 moves down, and the rubber ring 213 is in a stretched state and disengages from the electromagnet 212, exposing the electromagnet 212. The upper surface of the rubber ring 213 is flush with the surface of the electromagnet 212, which does not affect the contact between the sheet and the electromagnet 212. The Z-axis moving module 19 drives the vertical plate 11 to move down. When the sanding belt 12 holds the sheet, the trigger plate 221 acts to drive the conductive ring to contact. The electromagnet 212 is energized and superimposed with the permanent magnet 217 to fix the sheet. After grinding, the vertical plate 11 moves up, the conductive ring separates and the power is cut off, and the sheet can be easily removed. The rubber ring 213 automatically cleans the debris on the surface of the electromagnet 212.

[0071] Automatic application of auxiliary materials: When the sanding belt 12 moves up and down, the vertical rod 134 drives the piston 136 to reciprocate in the vertical cylinder 133, and uses the pressure difference to draw auxiliary materials from the paste box 141, and evenly apply them to the sanding belt 12 through the three-way valve 144 and the paste outlet 146; when no application is needed, the three-way valve 144 is switched to allow the material to flow back, avoiding waste and curing.

[0072] Precise positioning and movement: The X-axis moving module 18 and the Y-axis moving module 17 drive the moving base 15 to move the plate horizontally, while the Z-axis moving module 19 adjusts the height of the vertical plate 11 to achieve grinding at different positions of the plate and adapt to diverse processing needs.
