Description

Technical Field

[0001] The invention relates to the technical field of solid plate surface treatment, in particular to a polycarbonate solid plate surface treatment device. Background Art

[0002] Polycarbonate is a unique thermoplastic engineering plastic that combines high-performance mechanical, optical and thermal properties. It is widely used in the manufacture of various products, such as solid flat panels, hollow flat panels, U-shaped lock panels and other panels. Among them, polycarbonate solid flat panels have excellent impact resistance, and are thinner and lighter than glass, with a very high ignition point and are not easy to break. They are widely used in building lighting, indoor and outdoor decoration, lighting fixtures and other products. During production, in order to improve the physical and optical properties of polycarbonate solid flat panels to better meet the needs of specific applications, the transparency of polycarbonate solid flat panels can be increased by grinding, reducing light scattering, and obtaining a smooth, high-gloss mirror effect.

[0003] However, there are still the following problems in the process of polishing polycarbonate solid plates: the traditional single-sided polishing method requires the solid plate to be flipped over after polishing one side and then processed on the other side. The flipping and repositioning operations will affect the overall processing efficiency, especially in batch polishing operations. At the same time, repositioning after flipping may cause position errors, which in turn affects the consistency and polishing quality of the upper and lower surfaces of the solid plate. Secondly, applying polishing force to the solid plate from only one direction will cause uneven local pressure on the solid plate, and the solid plate is prone to offset. Its stability needs to be improved, and it also has a certain impact on the uniformity of polishing. Summary of the invention

[0015] 2. The present invention adopts a method of using two grinding mechanisms to simultaneously perform comprehensive and sufficient grinding on the upper and lower surfaces of the solid flat plate. This grinding method can not only greatly shorten the processing time and improve the grinding efficiency, but also help to maintain the uniform consistency of the grinding of both surfaces of the solid flat plate and improve the grinding quality.

A telescopic spring 311 is connected between the outer side of the corner of the L-shaped clamp 31 and the corresponding sliding groove wall. A fixing hole 312 is provided on the L-shaped clamp 31. Two connecting plates 223 distributed left and right are installed between the two front and rear opposite guide groove plates 216. A connecting plate 223 distributed left and right is installed between the upper and lower grinding mechanisms 2. A fixing part for fixing the L-shaped clamp 31 is provided, and the fixing part includes a limiting rod 313 installed on one side of the connecting plate 223 close to the workbench 1 and matched with the corresponding fixing hole 312, a frustum section is provided at the lower end of the limiting rod 313 located at the top, and a plug column 314 is installed at the lower end of the frustum section and is plugged and matched with the corresponding limiting rod 313 located below, the limiting rod 313 below is located at the lower side of the L-shaped clamp 31, and a connecting part is provided between the two upper and lower opposite mounting blocks 213, and the connecting part includes a connecting block 221 installed at the lower end of the upper mounting block 213, and a connecting groove matching with the corresponding connecting block 221 is provided at the upper end of the mounting block 213 located at the bottom.

[0033] In the initial state, the upper grinding mechanism 2 is in a position away from the workbench 1, and the lower grinding mechanism 2 is in a position close to the workbench 1 and located below the rectangular through groove 11. At the same time, the two side grinding rollers 214 in the upper and lower grinding mechanisms 2 are in a state of being away from each other, and the elastic telescopic plates 219 connected to the U-shaped plates 218 are in a retracted state. With the cooperation of the movable column 220 and the guide groove plate 216, the middle grinding roller 217 and the corresponding side grinding roller 214 always remain flush with each other. During work, the solid flat plate to be polished can be placed in the rectangular through groove 11 first, and placed between the upper ends of the left and right side grinding rollers 214 and the middle grinding roller 217 below, and also between the four L-shaped clamps 31. The left and right side grinding rollers 214 and the middle grinding roller 217 below can provide a stable multi-point bottom support for the solid flat plate, and the four L-shaped clamps 31 can elastically limit the solid flat plate circumferentially under the action of the corresponding telescopic springs 311.

[0034] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 and Figure 8 The upper ends of the two front and rear guide groove plates 216 at the bottom, which are away from each other, are each equipped with a support plate 222 fixedly connected to the lower end surface of the workbench 1. The sides of the two left and right side grinding rollers 214, which are away from each other, are each provided with a guide member for limiting and guiding the side grinding rollers 214. The guide member includes a longitudinal plate 224 installed between two front and rear opposite mounting blocks 213 at one end away from the workbench 1. A guide plate 225 is installed in the middle of the side of the longitudinal plate 224 away from the middle grinding roller 217. A fixing plate 226 slidably connected to the corresponding guide plate 225 is installed on the side of the connecting plate 223 close to the workbench 1. The fixing plate 226 located at the bottom is fixedly connected to the lower end surface of the workbench 1.

[0035] See also Figure 1 , Figure 2 and Figure 3, a driving component for driving the grinding mechanism 2 located above to move up and down and a moving member for controlling the up and down movement of the U-shaped frame 21 located above are provided at the upper end of the workbench 1. The driving component includes four vertical guide rails 111 which are installed at the upper end of the workbench 1, are located outside the rectangular through groove 11 and are distributed in a rectangular shape. A top plate 112 is slidably installed up and down between the four vertical guide rails 111. Two connecting columns 113 which are distributed front and back and are fixedly connected to the top plate 112 are installed at the upper ends of the left and right two connecting plates 223 located above. Among them, two electric sliders 116 which are slidably installed on two vertical guide rails 111 located on the same diagonal line and are fixedly connected to the upper end surface of the top plate 112. The moving member includes a cylinder 114 installed on the top plate 112. The lower end of the pushing section of the cylinder 114 is installed with a sliding plate 115 which is slidably connected to the upper end of the horizontal section of the U-shaped frame 21 located above.

[0036] Please refer to Figure 1-Figure 8 , after the placement of the solid flat plate is completed, the electric slider 116 can drive the top plate 112 to move downward along the corresponding vertical guide rail 111. The top plate 112 drives the entire grinding mechanism 2 located above to move downward synchronously through the cylinder 114, the sliding plate 115 and the connecting column 113 until the left and right two side grinding rollers 214 and the middle grinding roller 217 located above are simultaneously pressed against the upper end of the solid flat plate. During this process, the side grinding rollers 214 located above can drive the mounting blocks 213 on their front and rear sides to move downward synchronously. The connecting plates 223 located above can drive the corresponding limiting rods 313 to move downward synchronously. The longitudinal plates 224 located above drive the corresponding guide plates 225 to move downward synchronously. Since the grinding mechanism 2 located below is fixed to the lower end of the workbench 1 under the action of the corresponding fixing plates 226 and support plates 222, the mounting blocks 213, the limiting rods 313, the longitudinal plates 224 and the guide plates 225 located below are also fixed below the workbench 1. The mounting blocks 213 located above gradually insert the connecting blocks 221 at their lower ends into the connecting grooves at the upper ends of the corresponding mounting blocks 213 located below. Under the action of the mounting blocks 213, the connecting blocks 221 and the connecting grooves on the upper and lower sides, the two side grinding rollers 214 facing each other up and down can form a stable whole.

[0037] The L-shaped plate 31 is fixed to the upper and lower surfaces of the L-shaped plate 31, and the upper and lower surfaces of the L-shaped plate 31 are fixed to the upper and lower surfaces of the L-shaped plate 31.

[0038] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 , a matching rod 227 is installed on the upper end of the guide plate 225 located at the bottom, away from the corresponding longitudinal plate 224, and a matching slot plate 228 matching the corresponding matching rod 227 is installed on the lower end of the guide plate 225 located at the top, away from the corresponding longitudinal plate 224. A guide slot 229 that slides left and right with the corresponding matching slot plate 228 is opened on the upper end of the workbench 1. The position corresponding to the connecting plate 223 at the upper end of the workbench 1 is provided with a limiter for upper and lower limiting the guide plate 225. The limiter is located on the side of the fixed plate 226 away from the corresponding longitudinal plate 224. The limiter includes two vertical plates 230 that are distributed front and back about the guide slot 229 and are installed on the upper end of the workbench 1. The side close to the front and rear vertical plates 230 is opened. A triangular clamping block 231 is slidably installed in the mounting groove. The inclined surfaces of the front and rear triangular clamping blocks 231 are arranged opposite to each other, and a side spring 232 is connected between the triangular clamping block 231 and the corresponding mounting groove wall.

[0039] When the guide plate 225 at the top moves downward, it can drive the corresponding matching slot plate 228 to move downward synchronously, and the matching slot plate 228 gradually slides and cooperates with the corresponding matching rod 227 at the bottom, and finally the matching slot plate 228 can move downward to conflict with the corresponding guide plate 225. The connection and cooperation between the matching slot plate 228 and the matching rod 227 can increase the connection stability between the two upper and lower opposite guide plates 225. In addition, when the guide plate 225 at the top moves downward, it can conflict with the inclined surfaces of the front and rear triangular blocks 231 in the corresponding limiter and enter between the front and rear corresponding vertical plates 230. The front and rear triangular blocks 231 can be synchronously moved in the opposite direction to the corresponding installation grooves under the downward pressure, and the side springs 232 shrink synchronously with the movement of the corresponding triangular blocks 231. After the upper guide plate 225 moves down and passes through the triangular block 231, the front and rear triangular blocks 231 can move synchronously towards each other to the upper end of the corresponding guide plate 225 under the rebound force of the corresponding side springs 232. Subsequently, the upper guide plate 225 can use external force to synchronously push the front and rear triangular blocks 231 in opposite directions when moving up, so that the guide plate 225 can smoothly break away from the limiting member. The upper guide plate 225 can be limited in the up and down and front and back directions through the cooperation between the vertical plate 230 and the triangular block 231. Under the connection and cooperation between the matching slot plate 228 and the matching rod 227, the lower guide plate 225 is also limited. In addition, the guide plate 225 can also limit the corresponding connecting plate 223, fixing member and connecting member through the fixing plate 226.

[0040] In the subsequent process of the side grinding roller 214 moving back and forth left and right to grind the solid flat plate, the front and rear two mounting blocks 213 connected to the side grinding roller 214 can drive the guide plate 225 to move synchronously along the corresponding fixed plate 226 through the longitudinal plate 224, and the matching slot plate 228 can move synchronously along the corresponding guide slot 229. Through the cooperation between the guide plate 225 and the fixed plate 226, and between the matching slot plate 228 and the guide slot 229, a stable guide can be provided for the movement of the side grinding roller 214 to prevent the side grinding roller 214 from shaking during grinding and affecting the grinding effect.

[0041] See also Figure 1 , Figure 2 , Figure 3 and Figure 4, a linkage assembly is arranged between the upper and lower grinding mechanisms 2. The linkage assembly includes side plates 241 installed at the front and rear ends of the U-shaped frame 21. Linkage gears 242 are arranged on both the front and rear sides of the workbench 1. Vertical racks 243 are meshed on both the left and right sides of the linkage gears 242. The vertical rack 243 on the left is installed at the lower end of the corresponding upper side plate 241 and is in vertical sliding fit with the corresponding lower side plate 241. The vertical rack 243 on the right is vertically slidably installed on the corresponding lower side plate 241 and is in vertical sliding fit with the corresponding upper side plate 241. A locking member for locking the corresponding vertical rack 243 is arranged at the upper end of the lower side plate 241. The locking member includes a moving plate 244 fixedly connected to the vertical rack 243 on the right. Two connecting springs distributed left and right with respect to the corresponding vertical rack 243 are connected between the moving plate 244 and the upper end of the corresponding side plate 241. An electric telescopic rod 246 installed at the upper end of the corresponding side plate 241 is arranged on the right side of the moving plate 244. A C-shaped plate 248 is installed at the left end of the telescopic section of the electric telescopic rod 246.

[0042] When the upper grinding mechanism 2 moves downward as a whole, the vertical rack 243 on the left moves downward synchronously with the upper side plate 241. The linkage gear 242 rotates synchronously therewith and drives the vertical rack 243 on the right to move upward along the lower side plate 241. The moving plate 244 moves upward synchronously with the corresponding vertical rack 243, and the connecting springs expand synchronously therewith. After the vertical rack 243 on the right and the moving plate 244 complete the upward movement, the C-shaped plate 248 can be pushed to move leftward by the electric telescopic rod 246 until the moving plate 244 is caught between the upper and lower horizontal sections of the C-shaped plate 248, completing the locking between the vertical rack 243 on the right and the lower side plate 241.

[0043] Please refer to Figure 2-Figure 4After the connection, coordination and locking between the upper and lower grinding mechanisms 2 are completed, the upper and lower surfaces of the solid flat plate can be polished synchronously by using the side grinding rollers 214 and the middle grinding roller 217 on the upper and lower sides. Specifically, the cylinder 114 can be used to push the upper shaped frame 21 to move up and down reciprocatingly, and the existing driving source can be used to drive the side grinding rollers 214 and the middle grinding rollers 217 to work synchronously. The upper shaped frame 21 can drive the corresponding connecting rods 212 on the left and right sides to open and close synchronously through the connecting shaft 211. When closing, the angle between the connecting rods 212 on the left and right sides is turned from the initial obtuse angle to an acute angle, and the connecting rod 212 can be reciprocated left and right along the corresponding guide groove plate 216 through the sliding column 215 to ensure that the connecting rod 212 can pass through the mounting block 213 The corresponding side grinding roller 214 is driven to perform smooth left and right reciprocating grinding on the surface of the solid flat plate. The elastic telescopic plate 219 is synchronously extended and retracted with the movement of the profile frame 21, but the middle grinding roller 217 can always grind the surface of the solid flat plate. The connecting rods 212 on the left and right sides and the side grinding rollers 214, the guide groove plate 216, the middle grinding roller 217 and the solid flat plate form multiple triangular structures, thereby increasing the structural stability of the side grinding rollers 214 and the middle grinding rollers 217 during the grinding process. It should be noted that in order to ensure that the solid flat plate is always in a stable state during the grinding process, the side grinding rollers 214 on the left and right sides always maintain a certain distance from the middle grinding roller 217, thereby maintaining multi-point and balanced support for the solid flat plate.

[0044] At the same time, under the action of the vertical racks 243, the linkage gear 242 and the locking parts on the left and right sides, the side plate 241 located at the bottom can drive the lower Q-shaped frame 21 to move back and forth synchronously with the vertical rack 243 located on the right side. Since the two upper and lower side grinding rollers 214 opposite to each other are connected and cooperated with each other, the upper and lower grinding mechanisms 2 can cooperate to perform synchronous and consistent grinding on the upper and lower surfaces of the solid flat plate. The grinding forces of the upper and lower grinding mechanisms 2 on the solid flat plate can offset each other, ensuring that the solid flat plate is subjected to uniform and balanced forces during the grinding process, thereby improving the grinding quality of the solid flat plate. In addition, grinding the upper and lower surfaces of the solid flat plate at the same time is also conducive to improving the grinding efficiency.

[0045] See also Figure 3 and Figure 8A pushing member for pushing the linkage assembly to move left and right is provided at the upper end of the workbench 1, and the pushing member includes a moving groove 121 opened on both the front and rear sides of the workbench 1, and the rectangular groove 11 is located between the moving grooves 121. A moving block 122 is installed in the moving groove 121 for sliding left and right. A rotating shaft 123 that cooperates with the workbench 1 to slide left and right is installed on the side away from the front and rear moving blocks 122. The linkage gear 242 is rotatably connected to the corresponding rotating shaft 123. A guide rod 124 that is connected to the corresponding upper and lower side plates 241 for sliding up and down is installed on the moving block 122. A supporting spring 125 is connected between the lower end of the guide rod 124 and the lower end of the corresponding side plate 241 located below. A pushing plate is installed on the upper right end of the moving block 122, and the right end of the pushing plate is connected to the left end of the pushing section of the electric push rod 126 installed on the upper end of the workbench 1. The stiffness coefficient of the support spring 125 is much greater than the stiffness coefficient of the connecting spring, and the support spring 125 has sufficient stiffness coefficient to ensure the stability of the position of the support frame 21 before grinding, so that the left and right side grinding rollers 214 and the middle grinding roller 217 located below can stably support the solid plate.

[0046] During the synchronous operation of the upper and lower grinding mechanisms 2, the guide rod 124 can connect and guide the two shaped frames 21 to move up and down through the cooperation with the side plate 241, further improving the stability between the upper and lower grinding mechanisms 2. In order to make the solid flat plate more evenly and fully ground, the side grinding roller 214 and the middle grinding roller 217 can be reciprocated left and right. Specifically, the front and rear electric push rods 126 can synchronously push the moving block 122 to move back and forth along the corresponding moving groove 121 through the push plate. The guide rod 124 moves synchronously with the moving block 122 and drives the upper and lower side plates 241 and the shaped frame 21 to move synchronously. Among them, the shaped frame 21 located at the top can move left and right along the slide plate 115, and the linkage assembly moves synchronously therewith. The connecting rods 212, the elastic expansion plate 219, the side grinding rollers 214 and the middle grinding rollers 217 on the left and right sides are driven to move synchronously through the connecting shaft 211. The guide groove plate 216 remains stationary under the action of the connecting plate 223 and the connecting column 113. The connecting rod 212 can drive the sliding column 215 and the elastic expansion plate 219 can drive the moving column 220 to move synchronously along the corresponding guide groove plate 216. In this process, the side grinding rollers 214 and the middle grinding rollers 217 can fully and comprehensively grind the un-grinded area of ​​the solid flat plate.

[0047] After completing the comprehensive grinding of the upper and lower surfaces of the solid flat plate, the side grinding rollers 214 and the middle grinding rollers 217 in the upper and lower grinding mechanisms 2 can be reset by the cooperation between the moving parts and the pushing parts, and then the limit of the guide plate 225 by the limit part can be released first, and then the upper grinding mechanism 2 can be driven by the driving assembly to move up and reset, and the cooperation between the guide part, the connecting part and the fixing part can be released synchronously, and the L-shaped clamping plate 31 can be released from the fixation with the solid flat plate, and finally the polished solid flat plate can be taken out, and other solid flat plates can be polished in the same way as above.
