Description

Technical Field

[0001] The present invention belongs to the technical field of sheet polishing, and particularly relates to an automatic grinding and polishing device for sheet processing. Background Art

[0002] Sheet grinding and polishing is a common process in sheet processing. In scenarios such as architectural decoration, furniture, and electronic products, the smoothness of the sheet surface directly affects the product grade. Also, in mass production, surface polishing can eliminate color differences and processing marks, ensuring surface consistency among different batches or components. After the surface of metal sheets is polished, the oxide layer and micropores can be removed, facilitating subsequent spraying, electroplating, or anodizing treatments, and enhancing the rust and corrosion resistance. After polishing, transparent materials such as glass and acrylic can reduce light scattering and improve the light transmittance or reflection effect (such as mirrors, display panels).

[0003] When polishing a sheet, generally, the sheet is first fixed, and then a polishing wheel is held by hand or driven by a robotic arm to polish the surface of the sheet. For example, a sheet polishing device disclosed in the publication number CN222222185U. First, an operator places the sheet to be polished on a placement rack, makes the junction of the two side edges of the sheet abut against two buffer plates, positions the sheet on the placement rack, and then polishes the upper end of the sheet through the polishing wheel.

[0004] For existing sheet polishing devices, although they can achieve sheet polishing, when polishing both the upper and lower ends of the sheet, the sheet is fixed on a fixture, and one end of the sheet is polished. After polishing one end of the sheet, the sheet is removed from the fixture, flipped, and then fixed on the fixture again for polishing the other end. This requires two times of clamping and disassembling the sheet, resulting in a relatively complex sheet polishing operation. Summary of the Invention

The negative pressure pipe absorbs the polishing impurities at the upper end of the plate through the suction head, avoiding dust adhering to the polishing shaft and affecting the polishing effect of the polishing shaft, and also avoiding dust overflow during the polishing of the plate. Moreover, the suction head can absorb the heat on the polishing shaft, avoiding heat accumulation, and avoiding physical changes such as expansion and deformation on the surface of the plate caused by heat, which will affect the uniformity and precision of polishing, avoiding the polishing shaft working in a high-temperature environment, and accelerating the wear of the polishing tool, and avoiding the wear and deformation of the polishing shaft at high temperature, which will affect the polishing effect and the service life of the polishing shaft;

[0019] 3. Support plates that can move up and down are arranged above and below the moving plate.

Detailed implementation manners

[0034] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the attached drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0035] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0036] As Figures 1-8 shown, an automatic grinding and polishing device for sheet processing provided by an embodiment of the present invention includes a frame 101, and further includes: a moving plate 103, and a guiding chute 102 horizontally arranged on the side wall of the frame 101. A guiding part 104 is arranged on the moving plate 103, and the guiding part 104 is slidably connected in the guiding chute 102; a moving assembly 3 is arranged on the frame 101, and the moving assembly 3 is used to drive the moving plate 103 to move; a through placing groove 105 is arranged on the moving plate 103, and a clamping assembly 2 is arranged in the placing groove 105, and the clamping assembly 2 is used to fix the sheet in the placing groove 105; elastic telescopic rods 106 are rotatably connected to the inner walls of the front and rear sides of the frame 101, a polishing shaft 107 is rotatably connected between the two elastic telescopic rods 106, a rotating assembly 4 is arranged on the elastic telescopic rod 106, and the rotating assembly 4 is used to drive the polishing shaft 107 to rotate; first hydraulic cylinders 108 are rotatably connected to the inner walls of the front and rear sides of the frame 101, and the telescopic ends of the first hydraulic cylinders 108 are rotatably connected to the elastic telescopic rods 106.

[0037] In an embodiment of the present invention, during use, the first hydraulic cylinder 108 extends. The polishing shaft 107 is located above the moving plate 103, and the moving plate 103 moves away from the polishing shaft 107. A plate is placed in the placement groove 105, and the clamping assembly 2 fixes the plate in the placement groove 105. The moving assembly 3 drives the moving plate 103 to move towards the polishing shaft 107. When the polishing shaft 107 contacts the upper end of the plate, the elastic telescopic rod 106 presses the polishing shaft 107 against the upper end of the plate by elastic force. The rotating assembly 4 drives the polishing shaft 107 to rotate, and the rotating polishing shaft 107 grinds and polishes the upper end of the plate until the moving plate 103 drives the plate to completely pass below the polishing shaft 107. Subsequently, the moving plate 103 drives the plate to move in the reverse direction and reset. The first hydraulic cylinder 108 contracts, the first hydraulic cylinder 108 drives the elastic telescopic rod 106 to rotate downward, and the elastic telescopic rod 106 drives the polishing shaft 107 to be located below the moving plate 103. The moving plate 103 drives the plate to pass above the polishing shaft 107, and the polishing shaft 107 grinds and polishes the lower end of the plate. Then the moving plate 103 drives the plate to move in the reverse direction and reset, thereby completing the grinding and polishing process of the upper and lower ends of the plate. The plate can be taken out of the placement groove 105. Through one-time clamping of the plate, the upper and lower ends of the plate are automatically ground and polished, reducing the number of clamping times during the grinding and polishing of the plate, thereby simplifying the steps of grinding and polishing the plate and improving the efficiency of grinding and polishing the plate.

[0038] As Figure 1 and Figure 4 shown, as a preferred embodiment of the present invention, the clamping assembly 2 includes a clamping plate 201 horizontally slidably connected to the inner wall of the placement groove 105. A connecting block 204 is fixed to the upper end of the clamping plate 201. A first cylinder 202 is fixed to the upper end of the moving plate 103. The telescopic end of the first cylinder 202 is connected to the connecting block 204. An avoidance groove 203 for avoiding the movement of the connecting block 204 is provided on the moving plate 103.

[0039] In an embodiment of the present invention, when the plate is in the placement groove 105, the first cylinder 202 extends, the first cylinder 202 drives the clamping plate 201 to move, and the clamping plate 201 cooperates with the inner wall of the placement groove 105 to fix the plate. The first cylinder 202 contracts, the first cylinder 202 drives the clamping plate 201 away from the placement groove 105, and thus the plate is released.

[0040] As Figure 1 and Figure 4 shown, as a preferred embodiment of the present invention, the moving assembly 3 includes a threaded sleeve 301 fixed to the guiding portion 104, and a lead screw 302 rotatably connected to the side wall of the frame 101. The lead screw 302 is threadedly connected to the threaded sleeve 301. A first motor 303 is fixed to the frame 101. The rotating end of the first motor 303 is connected to the lead screw 302.

[0041] In the embodiment of the present invention, the first motor 303 drives the lead screw 302 to rotate. Under the guiding action of the guiding chute 102 and the guiding portion 104, the rotating lead screw 302 drives the threaded sleeve 301 to move through a threaded transmission manner. The threaded sleeve 301 drives the guiding portion 104 to move, and the guiding portion 104 drives the moving plate 103 to move.

[0042] As Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 shown, as a preferred embodiment of the present invention, the elastic telescopic rod 106 includes a telescopic sleeve 1061, a telescopic rod 1062 and a tension spring 1063. The telescopic rod 1062 is slidably connected inside the telescopic sleeve 1061. The two ends of the tension spring 1063 are respectively connected to the telescopic sleeve 1061 and the telescopic rod 1062. The telescopic sleeve 1061 is rotatably connected to the inner wall of the frame 101. The telescopic end of the first hydraulic cylinder 108 is rotatably connected to the telescopic sleeve 1061. The polishing shaft 107 is rotatably connected to the telescopic rod 1062.

[0043] In the embodiment of the present invention, when the polishing shaft 107 contacts the plate, the tension spring 1063 pulls the telescopic rod 1062, and the telescopic rod 1062 drives the polishing shaft 107 to abut against the plate.

[0044] As Figure 5 , Figure 6 and Figure 7 shown, as a preferred embodiment of the present invention, the rotating assembly 4 includes a second motor 401 fixed on the telescopic rod 1062, and a driving gear 402 fixed on the rotating end of the second motor 401. A transmission gear is fixed on the polishing shaft 107, and the transmission gear meshes with the driving gear 402.

[0045] In the embodiment of the present invention, the second motor 401 drives the driving gear 402 to rotate. The driving gear 402 drives the transmission gear to rotate, and the transmission gear drives the polishing shaft 107 to rotate.

[0046] As Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 10 , Figure 11 , Figure 12As shown, as a preferred embodiment of the present invention, a negative pressure pipe 701 is provided between two elastic telescopic rods 106. Both ends of the negative pressure pipe 701 are rotatably connected to two telescopic rods 1062 respectively. A plurality of suction heads 702 are installed on the negative pressure pipe 701. One end of the negative pressure pipe 701 is connected to the hose of the vacuum cleaner, and the other end of the negative pressure pipe 701 is connected to a swing rod 705. A fixed shaft 706 is fixed on the swing rod 705. A sector-shaped sunk groove one 704 is provided on the telescopic rod 1062. The swing rod 705 is rotatably connected in the sector-shaped sunk groove one 704. A torsion spring 703 is fixed on the negative pressure pipe 701, and the end of the torsion spring 703 is fixed on the telescopic rod 1062. A sector-shaped sunk groove two 707 is provided on the inner wall of the frame 101, and the fixed shaft 706 is movably arranged in the sector-shaped sunk groove two 707.

[0047] In the embodiment of the present invention, when the hydraulic cylinder one 108 extends, the polishing shaft 107 is located above the moving plate 103. The torsion spring 703 drives the negative pressure pipe 701 to rotate, and the negative pressure pipe 701 drives the swing rod 705 to abut against one end of the sector-shaped sunk groove one 704. At this time, the suction head 702 is inclined downward. When the polishing shaft 107 polishes the upper end of the plate, the vacuum cleaner generates negative pressure in the negative pressure pipe 701. The negative pressure pipe 701 absorbs the polishing impurities at the upper end of the plate through the suction head 702, avoiding dust adhering to the polishing shaft 107 and affecting the polishing effect of the polishing shaft 107, and also avoiding dust overflow during plate polishing. Moreover, the suction head 702 can absorb the heat on the polishing shaft 107, avoiding heat accumulation and preventing the heat from causing physical changes on the plate surface, such as expansion and deformation, which will affect the polishing uniformity and accuracy, avoiding the polishing shaft 107 working in a high-temperature environment and accelerating the wear of the polishing tool, and avoiding the wear and deformation of the polishing shaft 107 at high temperature, which will affect the polishing effect and the service life of the polishing shaft 107.

[0048] When the hydraulic cylinder one 108 contracts, the telescopic sleeve 1061 and the telescopic rod 1062 drive the polishing shaft 107 to move below the moving plate 103. During this process, the telescopic rod 1062 drives the swing rod 705 and the fixed shaft 706 to move downward until the fixed shaft 706 contacts the lower end of the sector-shaped sunk groove two 707. The sector-shaped sunk groove two 707 pushes the fixed shaft 706 and the swing rod 705 to rotate upward, and the swing rod 705 drives the suction head 702 to rotate upward, thereby making the suction head 702 inclined upward and making the suction head 702 face the lower end of the plate, facilitating the suction head 702 to absorb polishing impurities and heat.

[0049] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 8 and Figure 9As shown, as a preferred embodiment of the present invention, L-shaped fixing frames 501 are fixed to both the upper and lower ends of the moving plate 103. Two guide shafts 502 are slidably connected to the L-shaped fixing frames 501. A support plate 504 is fixed to one end of the two guide shafts 502 close to the moving plate 103. A second cylinder 503 is fixed to one end of the L-shaped fixing frame 501 away from the moving plate 103. The telescopic end of the second cylinder 503 is connected to the support plate 504. A limit screw rod 505 is fixed to one end of the support plate 504 away from the moving plate 103. At least one nut 506 is threadedly connected to the limit screw rod 505.

[0050] In the embodiment of the present invention, when the upper end of the plate is ground and polished, the second cylinder 503 below the moving plate 103 extends. Under the guiding action of the guide shaft 502, the second cylinder 503 drives the lower support plate 504 to move upward. The lower support plate 504 supports the lower end of the plate, thereby avoiding the pressure when the polishing shaft 107 grinds and polishes the plate, which may cause the plate to deform. The second cylinder 503 above the moving plate 103 contracts, and the upper support plate 504 is above the polishing shaft 107, thus not affecting the movement of the polishing shaft 107 relative to the plate.

[0051] When the lower end of the plate is ground and polished, the second cylinder 503 above the moving plate 103 extends. Under the guiding action of the guide shaft 502, the second cylinder 503 drives the upper support plate 504 to move downward. The upper support plate 504 supports the upper end of the plate, thereby avoiding the pressure when the polishing shaft 107 grinds and polishes the plate, which may cause the plate to deform. The second cylinder 503 below the moving plate 103 contracts, and the lower support plate 504 is below the polishing shaft 107, thus not affecting the movement of the polishing shaft 107 relative to the plate.

[0052] When the support plate 504 moves, it can drive the limit screw rod 505 to move. The limit screw rod 505 moves relative to the L-shaped fixing frame 501 to adjust the position of the nut 506 on the limit screw rod 505. After the nut 506 contacts the L-shaped fixing frame 501, the movement of the limit screw rod 505 is restricted, thereby adjusting the stroke of the limit screw rod 505, and then adjusting the stroke of the support plate 504, so that the support plate 504 can support plates of different thicknesses.

[0053] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 8 and Figure 9As shown, as a preferred embodiment of the present invention, a plurality of supporting blocks 605 are evenly fixed to the upper end of the supporting plate 504 below the moving plate 103. A discharging plate 601 and a feeding plate 602 are fixed to the inner wall of the frame 101. A placing sink 603 is provided at the upper end of the feeding plate 602. A plurality of strip-shaped notches 604 for avoiding the plurality of supporting blocks 605 are provided on both the discharging plate 601 and the feeding plate 602.

[0054] In the embodiment of the present invention, the plate is placed in the placing sink 603, and the placing sink 603 positions the plate. The cylinders two 503 above and below the moving plate 103 are both in a contracted state, so that the supporting plates 504 above and below the moving plate 103 are both away from the moving plate 103. At this time, the feeding plate 602 is located between the moving plate 103 and the supporting blocks 605 on the lower supporting plate 504. The moving plate 103 moves above the feeding plate 602. The cylinder two 503 below the moving plate 103 extends. Under the guiding action of the guiding shaft 502, the cylinder two 503 drives the lower supporting plate 504 to move upward. The lower supporting plate 504 drives the supporting blocks 605 to move upward. The supporting blocks 605 pass through the strip-shaped notches 604 and lift the plate in the placing sink 603 until the plate is sent into the placing groove 105, thus realizing automatic material taking before the plate is ground and polished.

[0055] After the plate is ground and polished, the cylinder two 503 below the moving plate 103 extends. Under the guiding action of the guiding shaft 502, the cylinder two 503 drives the lower supporting plate 504 to move upward. The lower supporting plate 504 drives the supporting blocks 605 to support the lower end of the plate. The cylinder two 503 above the moving plate 103 contracts. The upper supporting plate 504 is above the polishing shaft 107, so as not to affect the movement of the polishing shaft 107 relative to the plate. The moving plate 103 drives the plate to move above the discharging plate 601. At this time, the supporting blocks 605 are located in the strip-shaped notches 604 of the discharging plate 601. The clamping assembly 2 releases the plate. The cylinder two 503 below the moving plate 103 contracts. Under the guiding action of the guiding shaft 502, the cylinder two 503 drives the lower supporting plate 504 to move downward. The lower supporting plate 504 drives the supporting blocks 605 to move downward. The supporting blocks 605 drive the plate to move downward, so that the supporting blocks 605 place the ground and polished plate on the discharging plate 601. The ground and polished plate is discharged. The worker places the plate on the feeding plate 602 and removes the plate on the discharging plate 601, avoiding delaying the grinding and polishing of the plate by the grinding and polishing device due to loading and unloading.

[0056] In the above embodiments of the present invention, an automatic grinding and polishing device for sheet processing is provided. When in use, the first hydraulic cylinder 108 extends, and the polishing shaft 107 is located above the moving plate 103. The second cylinders 503 above and below the moving plate 103 are both in a contracted state, so that the support plates 504 above and below the moving plate 103 are both far away from the moving plate 103. Place the sheet in the placement sink 603, and the placement sink 603 positions the sheet. The moving plate 103 moves above the feeding plate 602, and the second cylinder 503 below the moving plate 103 extends. Under the guiding action of the guiding shaft 502, the second cylinder 503 drives the lower support plate 504 to move upward. The lower support plate 504 drives the supporting block 605 to move upward. The supporting block 605 passes through the strip-shaped notch 604 and lifts the sheet in the placement sink 603 until the sheet is sent into the placement groove 105. The first cylinder 202 extends, and the first cylinder 202 drives the clamping plate 201 to move. The clamping plate 201 cooperates with the inner wall of the placement groove 105 to fix the sheet, thereby realizing automatic material taking before grinding and polishing the sheet;

[0057] The moving plate 103 drives the sheet to move towards the polishing shaft 107. When the polishing shaft 107 contacts the upper end of the sheet, the tension spring 1063 pulls the telescopic rod 1062, and the telescopic rod 1062 drives the polishing shaft 107 to press against the upper surface of the sheet. The rotating assembly 4 drives the polishing shaft 107 to rotate, and the rotating polishing shaft 107 grinds and polishes the upper end of the sheet. The lower support plate 504 drives the supporting block 605 to support the lower end of the sheet, thereby avoiding the pressure on the sheet during grinding and polishing by the polishing shaft 107, which may cause the sheet to deform, until the moving plate 103 drives the sheet to completely pass below the polishing shaft 107. Subsequently, the moving plate 103 drives the sheet to move in the reverse direction and reset. The first hydraulic cylinder 108 contracts, and the first hydraulic cylinder 108 drives the elastic telescopic rod 106 to rotate downward. The elastic telescopic rod 106 drives the polishing shaft 107 to be located below the moving plate 103;

[0058] The second cylinder 503 above the moving plate 103 extends. Under the guiding action of the guiding shaft 502, the second cylinder 503 drives the upper support plate 504 to move downward. The upper support plate 504 supports the upper end of the sheet, thereby avoiding the pressure on the sheet during grinding and polishing by the polishing shaft 107, which may cause the sheet to deform. The second cylinder 503 below the moving plate 103 contracts, and the lower support plate 504 is located below the polishing shaft 107, so as not to affect the movement of the polishing shaft 107 relative to the sheet. The moving plate 103 drives the sheet to pass above the polishing shaft 107, and the polishing shaft 107 grinds and polishes the lower end of the sheet;

[0059] The cylinder two 503 below the moving plate 103 extends. Under the guiding action of the guiding shaft 502, the cylinder two 503 drives the lower supporting plate 504 to move upward. The lower supporting plate 504 drives the supporting block 605 to support the lower end of the plate. The cylinder two 503 above the moving plate 103 contracts, and the upper supporting plate 504 moves upward and resets. The moving plate 103 drives the plate to move above the discharging plate 601. At this time, the supporting block 605 is located in the strip-shaped notch 604 of the discharging plate 601, and the clamping assembly 2 releases the plate. The cylinder two 503 below the moving plate 103 contracts. Under the guiding action of the guiding shaft 502, the cylinder two 503 drives the lower supporting plate 504 to move downward. The lower supporting plate 504 drives the supporting block 605 to move downward. The supporting block 605 drives the plate to move downward, so that the supporting block 605 places the polished plate on the discharging plate 601, thus completing the grinding and polishing of one plate. The moving plate 103 moves towards the feeding plate 602 and takes materials again.

[0060] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
