Description

Technical Field

[0001] The invention relates to the technical field of liquid crystal glass grinding, in particular to a liquid crystal glass high-efficiency grinding device. Background Art

[0002] Liquid crystal glass is a special glass substrate used to manufacture liquid crystal displays. It needs to be finely processed during the production process to ensure that the surface of the liquid crystal glass is smooth and free of defects. After the liquid crystal glass is cut into rectangles of a specific size according to requirements, it is usually necessary to grind the burrs on the edges of the liquid crystal glass through a grinding mechanism to make the edges of the liquid crystal glass smoother and more regular. In the prior art, when grinding the four sides of the rectangular liquid crystal glass, generally multiple grinding wheels are moved regularly along the four sides of the liquid crystal glass, so that the four sides are grinded sequentially or synchronously. At the same time, during the working process of the grinding wheel, it is necessary to continuously spray coolant to the grinding wheel through a nozzle to reduce the temperature of the grinding wheel surface and the edge of the liquid crystal glass, and to wash away the debris generated by grinding.

[0003] However, the conventional method of grinding the edge of liquid crystal glass has the following problems: 1. In the prior art, liquid crystal glass is usually in proportion to the size of a liquid crystal display, that is, it is a rectangle whose length is significantly greater than its width. In order to ensure the consistency of the grinding accuracy of each side of the liquid crystal glass during processing, when the four sides of the rectangular liquid crystal glass are grinded sequentially or simultaneously, the time required for a single grinding wheel to grind the long side must be significantly longer than the time required to grind the short side. That is to say, when the four edges of a single piece of liquid crystal glass are grinded simultaneously, the total time required depends on the length of the long side, that is, the time required for a single grinding wheel to grind one side of the long side. When the grinding wheel of the short side stops working, the grinding wheel of the long side still needs to continue grinding. This This results in a low overall efficiency for single-piece loading and single-piece grinding of batches of liquid crystal glass; and when multiple sets of grinding equipment are used to grind multiple pieces of liquid crystal glass at the same time, although the total number of liquid crystal glasses polished in the same time increases, the number of grinding wheels and supporting equipment also increases, resulting in an increase in the overall processing cost; 2. When loading and unloading the liquid crystal glass, the processed liquid crystal glass is usually unloaded first, and then the liquid crystal glass to be processed is loaded and conveyed to the grinding mechanism for processing. The above-mentioned operation method of loading and unloading the liquid crystal glass in sequence is relatively cumbersome and inefficient, which will affect the efficiency of the overall grinding processing of the liquid crystal glass.

[0032] See also Figure 1 and Figure 2 The feeding mechanism 2 includes a supporting platform 21 fixedly arranged on the upper side of the base plate 1 by four rods, and the supporting platform 21 is provided with a positioning component 24 and a supporting component 22 distributed front and back, and a pushing component 23 located below the supporting component 22 and the positioning component 24, and a matching component 25 is commonly arranged on the pushing component 23 and the positioning component 24.

[0033] See also Figure 2 , Figure 3 and Figure 4 The supporting assembly 22 includes a display rack 221 which is symmetrically fixed on the upper side of the supporting platform 21 through a second rod, and the symmetrical display racks 221 are fixedly connected by a third rod. A stack of liquid crystal glasses is placed in each of the symmetrical display racks 221. L-shaped baffles 222 are fixedly arranged at the four corners of the display racks 221. A correction plate 223 with an inclined lower end is symmetrically fixedly arranged on the front side of the display rack 221. A discharge trough 224 located below the correction plate 223 and extending front to back is provided on the front surface of the display rack 221. A push trough 225 extending front to back is provided on the rear surface of the display rack 221. A sliding trough 226 extending up and down is provided on the lower surface of the display rack 221, wherein the front and rear ends of the sliding trough 226 are respectively connected to the discharge trough 224 and the push trough 225.

[0034] See also Figure 2 , Figure 3 and Figure 4 The pushing assembly 23 includes a pneumatic cylinder 231 fixedly arranged on the upper side of the supporting platform 21 through a support and located between the left and right display racks 221. The telescopic end of the pneumatic cylinder 231 is fixedly provided with a rectangular connecting plate 232 that moves forward and backward. The left and right ends of the rectangular connecting plate 232 are symmetrically fixed with L-shaped moving racks 233 located behind the display racks 221, wherein the L-shaped moving rack 233 is an inverted L-shaped plate, and a spring rod 234 is symmetrically elastically slidably arranged on the horizontal section of the L-shaped moving rack 233. The upper ends of the left and right symmetrical spring rods 234 are commonly fixed with a pushing block 235 with a slope on the rear side, wherein the hardness of the pushing block 235 is lower than that of the liquid crystal glass, and the left and right symmetrical pushing blocks 235 slide forward and backward along the corresponding sliding grooves 226 respectively.

[0035] When the rectangular connecting plate 232 is driven to move forward from the rear end by the pneumatic cylinder 231, the L-shaped moving frames 233 at both ends of the rectangular connecting plate 232 drive the corresponding pushing blocks 235 to move forward synchronously, and the pushing blocks 235 move forward until they enter the pushing groove 225 on the corresponding display rack 221, and fit with the rear end of the lowest liquid crystal glass in the corresponding display rack 221. With the continuous driving of the pneumatic cylinder 231, the pushing blocks 235 continue to push the corresponding liquid crystal glass forward along the corresponding sliding groove 226 until the liquid crystal glass is pushed out of the corresponding discharge groove 224. At this time, the remaining liquid crystal glass moves downward to fill the position.

[0036] When the push block 235 is driven by the pneumatic cylinder 231 to move backward from the front end to reset, the push block 235 contacts the front end of the corresponding lowermost liquid crystal glass, and the front end of the liquid crystal glass cooperates with the inclined surface on the rear side of the corresponding push block 235, so that the push block 235 first moves downward to the lower side of the corresponding liquid crystal glass, until the push block 235 that continues to move backward is separated from the corresponding liquid crystal glass. At this time, under the action of the spring rod 234, the push block 235 moves upward and resets, so that the push block 235 can be driven by the pneumatic cylinder 231 to push the paired liquid crystal glasses located at the lower side forward synchronously until all the stack of liquid crystal glasses in the corresponding display rack 221 are pushed forward for loading.

[0037] See also Figure 2 , Figure 3 , Figure 5 and Figure 6 The positioning assembly 24 includes two groups of L-shaped limit plates 241 symmetrically fixedly arranged on the front side of the supporting platform 21, each group is composed of two L-shaped limit plates 241 symmetrically arranged on the upper side of the supporting platform 21, a positioning frame 242 is symmetrically and slidably arranged on the upper side of the supporting platform 21, and two spring rods 243 elastically and slidably connected to the supporting platform 21 are fixedly arranged at the four corners of the lower surface of the positioning frame 242, and a rotating seat 244 is symmetrically and fixedly arranged at the front end of the positioning frame 242, and a rotating plate 245 that cooperates with the corresponding L-shaped limit plate 241 for limiting the position is rotatably arranged between the symmetrical rotating seats 244, and a rotating shaft 246 rotatably connected to the corresponding rotating seat 244 is fixedly arranged at the lower end of the rotating plate 245, and a pad 247 is fixedly arranged on the end of the rotating shaft 246 away from the rotating plate 245, and a torsion spring 248 is fixedly arranged on the pad 247 and the side of the corresponding rotating seat 244 away from the rotating plate 245.

[0038] See also Figure 2 , Figure 3 , Figure 4 and Figure 5The matching component 25 includes two groups of guide frames 251 symmetrically distributed on the left and right sides, each group is composed of a guide frame 251 symmetrically fixedly arranged on the lower side of the corresponding positioning frame 242 through a rod member 4, and a guide groove 252 is opened on the left and right symmetrical guide frames 251, wherein the guide groove 252 is composed of a horizontal straight groove and an oblique groove distributed front and back, and the front side of the vertical section of the left and right symmetrical L-shaped movable frame 233 is symmetrically fixedly provided with a connecting rod 1 253, and the front end of the left and right symmetrical connecting rod 1 253 is jointly fixedly provided with a driving head 254 located between the corresponding left and right guide frames 251, and the left and right ends of the driving head 254 are symmetrically fixedly provided with a sliding shaft 255 that slidably cooperates with the corresponding guide groove 252.

[0039] When the L-shaped moving frame 233 moves forward from the rear end driven by the pneumatic cylinder 1 231, the L-shaped moving frame 233 then drives the corresponding driving head 254 to move forward synchronously through the connecting rod 1 253, and the driving head 254 then drives the sliding shafts 255 at both ends to move forward along the corresponding guide groove 252, and the sliding shafts 255 then first cooperate with the inclined section of the corresponding guide groove 252, so that the corresponding guide frame 251 and the positioning frame 242 move downward by a specific distance until the sliding shaft 255 enters the horizontal section of the corresponding guide groove 252, at which time the positioning frame 242 is just aligned with the discharge slot 224 on the front side of the corresponding display frame 221, and the pushing block 235 is just aligned with the corresponding liquid crystal display frame 251. The rear end of the glass is fitted, and with the continuous driving of the pneumatic cylinder 231, the pushing block 235 pushes the corresponding liquid crystal glass completely into the corresponding positioning frame 242, wherein the vertical section of the L-shaped limiting plate 241 can fit and limit the rotating plate 245, so that the rotating plate 245 is stably in a vertical state and cannot rotate, to ensure that when the liquid crystal glass is pushed into the positioning frame 242, the rotating plate 245 can stably fit and limit the front end of the liquid crystal glass. The above-mentioned operation method can realize the synchronous and stable pushing and limiting of the pairs of liquid crystal glasses in the corresponding positioning frames 242, thereby ensuring the stability of the subsequent conveying mechanism 3 when docking and taking materials for the pairs of liquid crystal glasses to be polished.

[0040] When the driving head 254 is driven by the pneumatic cylinder 1 231 to move backward and reset to the rearmost end, the driving head 254 then cooperates with the inclined section of the corresponding guide groove 252 through the sliding shaft 255, and under the synchronous action of the spring rod 243, the corresponding guide frame 251 and the positioning frame 242 can be synchronously moved upward and reset. When the positioning frame 242 is reset upward, it can simultaneously drive the liquid crystal glass to be polished to move upward and dock with the conveying mechanism 3 for loading. At this time, the rotating plate 245 is completely separated from the corresponding L-shaped limit plate 241, so that it can rotate to release the bonding with the front end of the liquid crystal glass. Limiting, wherein in the process of the liquid crystal glass moving upward, the correction plate 223 can correct and limit the corresponding liquid crystal glass through the inclined surface at the lower end. The above operation mode can not only realize the synchronous pushing and loading of the two stacks of liquid crystal glasses from bottom to top, but also ensure that the loading position always remains unchanged, so that the conveying mechanism 3 no longer needs to repeatedly move up and down to dock and pick up liquid crystal glasses at different heights, ensuring that the conveying mechanism 3 can quickly dock, pick up and transport paired liquid crystal glasses, thereby greatly simplifying the picking and conveying operations of the conveying mechanism 3 and improving the overall loading efficiency of the liquid crystal glass.

[0043] See also Figure 2 , Figure 3 , Figure 7 and Fig. 9 Each group of the adsorption components 32 includes two fixed plates 321 symmetrically fixed on the U-shaped connecting plate 314, and a base 322 is fixedly arranged at the four corners of the lower surface of the fixed plate 321. Four connecting rods 323 are evenly fixedly arranged on the lower side of the base 322. A vacuum suction cup 324 is commonly fixedly arranged at the lower ends of the four connecting rods 323, and a plurality of air holes 325 are evenly opened on the surface of the vacuum suction cup 324.

[0044] When the liquid crystal glass to be polished driven by the positioning frame 242 moves upward and resets synchronously, the vacuum suction cup 324 on the corresponding fixed plate 321 above the liquid crystal glass is then fitted with the upper surface of the liquid crystal glass, and the corresponding docked liquid crystal glass is positioned and taken out by vacuum adsorption, and then the electric slider 313 moves forward from the rear end along the guide rail 312, and the U-shaped connecting plate 314 drives the two fixed plates 321 with liquid crystal glasses positioned on the rear side to move forward synchronously, and the front end of the liquid crystal glass presses the upper end of the rotating plate 245 that is completely separated from the L-shaped limiting plate 241, so that the rotating plate 245 rotates forward to make way until it is completely separated from the liquid crystal glass. At this time, the pad 247 drives the rotating shaft 246 and the rotating plate 245 to rotate backward and reset under the action of the torsion spring 248. When the electric slider 313 moves to the front end, the two liquid crystal glasses to be polished are just moved to the top of the polishing mechanism 4, so that the two liquid crystal glasses to be polished can be loaded into the polishing mechanism 4 for processing.

[0049] When the paired liquid crystal glasses are to be polished synchronously, the two liquid crystal glasses to be polished are first transported to the top of the lifting platform 431 by the electric slider 1 313, and then the corresponding fixing plates 321 are driven to move upward by the two pneumatic cylinders 2 433 until the vacuum suction cups 324 on the fixing plates 321 below are attached to the lower surfaces of the corresponding liquid crystal glasses and the liquid crystal glasses are stably adsorbed and positioned. At this time, the adsorption and positioning of the upper surfaces of the two liquid crystal glasses are released, and then the positioned liquid crystal glasses are synchronously driven downward by the two pneumatic cylinders 2 433 to reset until the four sides of the two liquid crystal glasses are respectively aligned with the corresponding grinding wheels 423 (such as Figure 8 As shown), at this time, not only are the short sides of the same side of the two liquid crystal glasses collinear, but all the long sides are parallel and coplanar, so that the two electric sliders 413 are moved from one end of the corresponding guide rail 412 to the other end, so that the corresponding drive assembly 421 and the grinding wheel 423 can be ground along the short sides of the same side of the two liquid crystal glasses. At the same time, the three electric sliders 417 are moved from one end of the corresponding guide rail 416 to the other end, so that the corresponding drive assembly 421 and the grinding wheel 423 can be ground synchronously along the long sides of the corresponding liquid crystal glasses, wherein the middle grinding wheel 423 can simultaneously grind the adjacent long sides of the two liquid crystal glasses. In order to ensure the consistency of the grinding accuracy of the edges of the liquid crystal glasses, the moving speed of each electric slider 413 and each electric slider 417 must be the same.

[0050] Taking the LCD glass panel corresponding to the mainstream 16:10 ratio LCD display as an example, assuming that the polishing speed is 1 unit (i.e. 1 ratio), it takes 16 seconds to polish the long side of the LCD glass of this ratio and 10 seconds to polish the short side. Since the total time required for polishing the four edges of a single piece of LCD glass at the same time depends on the length of the long side, that is, the time required for a single grinding wheel 423 to polish one side of the long side, the total time required to polish a single piece of LCD glass of this ratio is 16 seconds, and the total time required to polish two pieces in sequence is 32 seconds; when the cost is increased by using multiple sets of polishing equipment to polish two pieces of LCD glass at the same time, although it only takes 16 seconds to polish the two pieces of LCD glass, at least 8 grinding wheels 423 are required to work synchronously, and when the short side grinding wheel 423 stops working, the long side grinding wheel 423 will still need to continue to polish for a long time; when through When the grinding mechanism 4 provided in the present invention grinds the 16:10 liquid crystal glass, not only can two pieces of liquid crystal glass be grinded at the same time by only five grinding wheels 423, but the total time required for grinding is only slightly greater than the sum of the time required for grinding the two short sides of the liquid crystal glass of this ratio, that is, slightly greater than 20 seconds; when the liquid crystal glass panel corresponding to the 21:9 ratio liquid crystal display of the same mainstream size is to be grinded, the grinding mechanism 4 in the present invention needs 21 seconds to grind two pieces of liquid crystal panels of this ratio by five grinding wheels 423, while the existing method of grinding two pieces of liquid crystal glass separately in sequence needs 42 seconds, and the method of grinding two pieces of liquid crystal glass synchronously by eight grinding wheels 423 needs 21 seconds. Therefore, according to the above conclusion, when grinding liquid crystal glass in batches, the grinding mechanism 4 in the present invention has obvious advantages in terms of the efficiency of the overall liquid crystal glass grinding process and the cost control of the overall processing.

[0051] When the two processed liquid crystal glasses are to be unloaded synchronously, the electric slider 1 313 is first moved to the rear end. At this time, the two fixing plates 321 on the front side of the U-shaped connecting plate 314 are respectively aligned with the corresponding processed liquid crystal glasses, and the two fixing plates 321 on the rear side of the U-shaped connecting plate 314 are respectively aligned with the liquid crystal glasses loaded in the corresponding positioning frame 242. Then, the corresponding processed liquid crystal glasses are driven to move upward by the pneumatic cylinder 2 433 until the upper surface of the processed liquid crystal glasses is attached to and docked with the vacuum suction cup 324 on the corresponding fixing plate 321 above, and the lower side can be released. The positioning and adsorption are performed, and at the same time, the two liquid crystal glasses to be polished are positioned and adsorbed by the vacuum suction cup 324 on the corresponding fixed plate 321 above the positioning frame 242, and finally the electric slider 313 is moved to the front end, so that the two liquid crystal glasses to be polished are moved to the top of the lifting platform 431 for loading, and at the same time, the two processed liquid crystal glasses are synchronously transported forward for unloading. The above operation method can realize the synchronous loading and unloading of the liquid crystal glasses, thereby greatly simplifying the overall loading and unloading operations of the liquid crystal glasses, thereby improving the overall transportation efficiency of the liquid crystal glasses and the overall grinding efficiency.
