Description

Technical Field

[0001] The present invention relates to the technical field of liquid crystal glass grinding, and specifically provides an efficient liquid crystal glass grinding device. Background Art

[0002] Liquid crystal glass is a special glass substrate used for manufacturing liquid crystal displays. During the production process, it needs to be finely processed to ensure that the surface of the liquid crystal glass is smooth and free of defects. After cutting the liquid crystal glass into rectangles of specific sizes according to requirements, it is usually necessary to grind the burrs on the edges of the liquid crystal glass through a grinding mechanism, so that the edges of the liquid crystal glass are smoother and more regular. In the prior art, when grinding the four sides of a rectangular liquid crystal glass, generally, multiple grinding wheels move regularly along the four sides of the liquid crystal glass to grind the four sides sequentially or simultaneously. At the same time, during the operation of the grinding wheels, it is necessary to continuously inject coolant into the grinding wheels through a nozzle to reduce the temperature on the surface of the grinding wheels and the edges of the liquid crystal glass, and to wash away the debris generated by grinding.

[0003] However, the traditional method of grinding the edges of liquid crystal glass has the following problems: 1. In the prior art, liquid crystal glass usually conforms to the size ratio of liquid crystal displays, that is, a rectangle with a length significantly greater than the width. During the processing, to ensure the consistency of the grinding accuracy of each side of the liquid crystal glass, when grinding the four sides of the rectangular liquid crystal glass sequentially or simultaneously, the time required for a single grinding wheel to grind the long side will definitely be significantly longer than the time required to grind the short side. That is to say, when grinding the four edges of a single liquid crystal glass 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 on the short side stops working, the grinding wheel on the long side still needs to continue grinding, which results in a low overall efficiency of single-piece feeding and single-piece grinding for a batch of liquid crystal glass. When multiple sets of grinding equipment are used to grind multiple liquid crystal glasses simultaneously, although the total number of liquid crystal glasses ground within the same time increases, it also increases the number of grinding wheels and supporting equipment, thus resulting in an increase in the overall processing cost. 2. When feeding and discharging the liquid crystal glass, usually, the processed liquid crystal glass is first discharged and then the liquid crystal glass to be processed is fed into the grinding mechanism for processing. The above operation method of sequentially feeding and discharging the liquid crystal glass is more cumbersome and has low efficiency, thus affecting the overall grinding efficiency of the liquid crystal glass.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The grinding mechanism provided by the present invention can realize grinding two liquid crystal glasses synchronously with fewer grinding wheels. At the same time, while ensuring the same grinding accuracy, a single grinding wheel can sequentially grind the two short sides on the same side of the two liquid crystal glasses, and the time required for it to grind the two short sides is basically the same as the time required to grind a single long side, so that the working hours of the short-side grinding wheel and the long-side grinding wheel are basically the same, and thus the overall efficiency of batch grinding of liquid crystal glasses can be greatly improved at a lower processing cost.

[0018] 2. Through the feeding mechanism of the present invention, not only can the two stacks of liquid crystal glasses distributed at intervals on the left and right be pushed and fed from bottom to top synchronously, but also the feeding position can be kept unchanged all the time, so that the conveying mechanism only needs to move horizontally to synchronously dock and pick up the paired liquid crystal glasses and quickly convey them into the grinding mechanism, thus greatly simplifying the operations of picking up and conveying of the conveying mechanism, and at the same time improving the overall feeding and grinding efficiency of the liquid crystal glasses.

[0019] 3. Through the conveying mechanism of the present invention, it can realize synchronous docking and picking up of the paired liquid crystal glasses to be ground fed by the feeding mechanism and the paired liquid crystal glasses that have been processed in the grinding mechanism. Thus, only through a single horizontal movement, the conveying mechanism can convey the paired liquid crystal glasses to be ground into the grinding mechanism for processing and convey the processed paired liquid crystal glasses forward for blanking. The above operation method can realize synchronous feeding and blanking conveying of the liquid crystal glasses, thus greatly simplifying the operations of overall feeding and blanking conveying of the liquid crystal glasses, and further improving the overall conveying efficiency of the liquid crystal glasses and the overall grinding and processing efficiency.

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figure 1 and a high-efficiency grinding device for liquid crystal glass, which includes a bottom plate 1. On the upper side of the bottom plate 1, there are a grinding mechanism 4 and a feeding mechanism 2 distributed front and back, and a conveying mechanism 3 located above the feeding mechanism 2 and the grinding mechanism 4.

[0032] Please refer to Figure 1 and Figure 2 . The feeding mechanism 2 includes a supporting table 21 fixedly arranged on the upper side of the bottom plate 1 through four rods one. On the supporting table 21, there are 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. A matching component 25 is jointly arranged on the pushing component 23 and the positioning component 24.

[0033] Please refer to Figure 2 , Figure 3 and Figure 4 . The supporting component 22 includes a placing frame 221 symmetrically and fixedly arranged on the upper side of the supporting table 21 through two rods two on the left and right. The left and right symmetric placing frames 221 are fixedly connected through a rod three. Inside the left and right symmetric placing frames 221, there is a stack of liquid crystal glass placed. At the four corners of the placing frame 221, there are L-shaped baffles 222 fixedly arranged. On the front side of the left and right symmetric placing frames 221, there are correction plates 223 with inclined lower ends symmetrically and fixedly arranged. On the front surface of the placing frame 221, there is a discharge slot 224 located below the correction plate 223 and penetrating front and back. On the rear surface of the placing frame 221, there is a pushing slot 225 penetrating front and back. On the lower surface of the placing frame 221, there is a sliding slot 226 penetrating up and down. Among them, the front and rear ends of the sliding slot 226 are respectively communicated with the discharge slot 224 and the pushing slot 225.

[0034] Please refer to Figure 2 , Figure 3 and Figure 4 . The pushing component 23 includes a pneumatic cylinder one 231 fixedly arranged on the upper side of the supporting table 21 through a support one and located between the left and right two placing frames 221. The telescopic end of the pneumatic cylinder one 231 is fixedly provided with a rectangular connecting plate 232 that moves back and forth. Symmetrically fixed at the left and right ends of the rectangular connecting plate 232 are L-shaped moving frames 233 located behind the placing frame 221. Among them, the L-shaped moving frame 233 is an inverted L-shaped plate member. On the horizontal section of the L-shaped moving frame 233, there are spring rods one 234 elastically and slidably arranged symmetrically on the left and right. The upper ends of the left and right symmetric spring rods one 234 are jointly fixedly provided with a pushing block 235 with an inclined rear side. Among them, the hardness of the pushing block 235 is lower than the hardness of the liquid crystal glass. The left and right symmetric pushing blocks 235 respectively slide back and forth along the corresponding sliding slots 226.

[0035] When the rectangular connecting plate 232 is driven by the first pneumatic cylinder 231 to move forward from the rearmost end, 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. The pushing blocks 235 move forward until they enter the pushing grooves 225 on the corresponding placing racks 221 and fit against the rear ends of the lowermost liquid crystal glasses in the corresponding placing racks 221. With the continuous driving of the first pneumatic cylinder 231, the pushing blocks 235 continuously push the corresponding liquid crystal glasses forward along the corresponding sliding grooves 226 until the liquid crystal glasses are pushed out from the corresponding discharge slots 224. At this time, the remaining liquid crystal glasses move downward to make up the position.

[0036] When the pushing block 235 is driven by the first pneumatic cylinder 231 to move backward from the foremost end to reset, the pushing block 235 contacts the front end of the corresponding lowermost liquid crystal glass. The front end of the liquid crystal glass cooperates with the inclined surface at the rear side of the corresponding pushing block 235, so that the pushing block 235 first moves downward to the lower side of the corresponding liquid crystal glass until the continuously backward moving pushing block 235 disengages from the corresponding liquid crystal glass. At this time, under the action of the first spring rod 234, the pushing block 235 moves upward to reset, so that the pushing block 235 can be driven by the first pneumatic cylinder 231 to synchronously push the paired liquid crystal glasses at the lowermost side forward until all the stacks of liquid crystal glasses in the corresponding placing racks 221 are pushed forward for feeding.

[0037] Please refer to Figure 2 、 Figure 3 、 Figure 5 and Figure 6 As shown in FIGS.

[0038] Please refer to Figure 2 、 Figure 3 、 Figure 4 and Figure 5, the fitting assembly 25 includes two sets of guide frames 251 symmetrically distributed left and right. Each set is composed of guide frames 251 symmetrically and fixedly arranged on the lower side of the corresponding positioning frame 242 through rod four. Guide grooves 252 are formed on the symmetrically distributed guide frames 251 left and right. The guide groove 252 is composed of a horizontal straight groove and an inclined groove distributed front and back. On the front sides of the vertical sections of the symmetrically distributed L-shaped moving frames 233 left and right, connecting rods one 253 are symmetrically and fixedly arranged left and right. The front ends of the symmetrically distributed connecting rods one 253 are jointly fixedly provided with a driving head 254 located between the corresponding left and right guide frames 251. Symmetrically fixed on the left and right ends of the driving head 254 are sliding shafts 255 that are slidably engaged with the corresponding guide grooves 252.

[0039] When the L-shaped moving frame 233 moves forward from the rearmost end driven by the first pneumatic cylinder 231, the L-shaped moving frame 233 drives the corresponding driving head 254 to move forward synchronously through the connecting rod one 253. The driving head 254 drives the sliding shafts 255 at both ends to move forward along the corresponding guide grooves 252. The sliding shafts 255 first cooperate with the inclined sections of the corresponding guide grooves 252, so that the corresponding guide frames 251 and positioning frames 242 move downward by a specific distance until the sliding shafts 255 enter the horizontal sections of the corresponding guide grooves 252. At this time, the positioning frame 242 is exactly aligned with the discharge slot 224 on the front side of the corresponding placing frame 221, and the pushing block 235 is exactly in contact with the rear end of the corresponding liquid crystal glass. With the continuous driving of the first pneumatic cylinder 231, the pushing block 235 pushes the corresponding liquid crystal glass completely into the corresponding positioning frame 242. 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 operation method can synchronously and stably push and limit the paired liquid crystal glasses into the corresponding positioning frames 242 respectively, so as to ensure the stability when the subsequent conveying mechanism 3 docks and picks up the liquid crystal glasses to be polished.

[0040] When the driving head 254 is driven by the air cylinder 231 to move backward and reset to the rearmost end, the driving head 254 cooperates with the inclined section of the corresponding guiding groove 252 through the sliding shaft 255, and under the synchronous action of the second spring rod 243, the corresponding guiding frame 251 and the positioning frame 242 can be synchronously moved upward to reset. When the positioning frame 242 resets upward, it can drive the pair of liquid crystal glasses to be polished upward at the same time to be butted and fitted with the conveying mechanism 3 for feeding. At this time, the rotating plate 245 is exactly completely separated from the corresponding L-shaped limiting plate 241, so that it can rotate to release the fitting limit on the front end of the liquid crystal glass. During the upward movement of the liquid crystal glass, the calibration plate 223 can calibrate and limit the corresponding liquid crystal glass through the inclined surface at the lower end. The above operation method can not only synchronously push and feed two stacks of liquid crystal glasses from bottom to top in sequence, but also ensure that the feeding position always remains unchanged, so that the conveying mechanism 3 no longer needs to move up and down repeatedly to dock and pick up liquid crystal glasses at different heights, ensuring that the conveying mechanism 3 can quickly dock and pick up and convey the paired liquid crystal glasses, thereby greatly simplifying the picking and conveying operations of the conveying mechanism 3 and improving the overall feeding efficiency of the liquid crystal glasses.

[0041] Please refer to Figure 1 and Figure 7 , the conveying mechanism 3 includes a conveying component 31 arranged on the upper side of the bottom plate 1, and two adsorption components 32 are arranged front and back on the conveying component 31.

[0042] Please refer to Figure 1 and Figure 7 , the conveying component 31 includes two U-shaped brackets 311 with openings facing downward, which are fixedly arranged on the upper side of the bottom plate 1 front and back. A first guide rail 312 is fixedly arranged between the horizontal sections of the two U-shaped brackets 311. Two electric sliders 313 are slidably arranged front and back on the first guide rail 312. A U-shaped connecting plate 314 is fixedly arranged on the lower sides of the two electric sliders 313.

[0043] Please refer to Figure 2 , Figure 3 , Figure 7 and Figure 9 , each adsorption component 32 includes two fixing plates 321 which are symmetrically fixed on the left and right sides of the U-shaped connecting plate 314. Four bases 322 are fixedly arranged at the four corners of the lower surface of the fixing plate 321. Four second connecting rods 323 are uniformly fixedly arranged on the lower sides of the bases 322. A vacuum chuck 324 is fixedly arranged at the lower ends of the four second connecting rods 323. A plurality of air holes 325 are uniformly formed on the surface of the vacuum chuck 324.

[0044] When the positioning frame 242 drives the liquid crystal glass to be polished to move upward and reset synchronously, the vacuum suction cups 324 on the corresponding fixed plate 321 above the liquid crystal glass are attached to the upper surface of the liquid crystal glass accordingly, and the liquid crystal glass to be docked is positioned and picked up through vacuum adsorption. Then, the electric slider 313 moves forward along the guide rail 312 from the rear end, and the U-shaped connecting plate 314 drives the two fixed plates 321 with the liquid crystal glass positioned at the rear side to move forward synchronously. 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, causing the rotating plate 245 to rotate forward to make way until it is completely separated from the liquid crystal glass. At this time, the backing plate 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 just move above the grinding mechanism 4, so that the two liquid crystal glasses to be polished can be loaded into the grinding mechanism 4 for processing.

[0045] Please refer to Figure 1 、 Figure 7 、 Figure 8 and Figure 9 ,the grinding mechanism 4 includes a guiding component 41 arranged on the upper side of the bottom plate 1, a grinding component 42 arranged on the guiding component 41, and a lifting component 43 located inside the guiding component 41. An adsorption component 32 is also arranged on the upper side of the lifting component 43, wherein the adsorption component 32 on the upper side of the lifting component 43 is arranged opposite to the adsorption component 32 on the conveying mechanism 3.

[0046] Please refer to Figure 7 、 Figure 8 and Figure 9 ,the guiding component 41 includes two groups of first struts 411 fixedly arranged on the upper side of the bottom plate 1 from front to back. Each group consists of two symmetric first struts 411 on the left and right. The four first struts 411 are distributed in a matrix. A second guide rail 412 is fixedly arranged between the two symmetric first struts 411 on the left and right. The two second guide rails 412 in the front and back are symmetrically arranged. Electric sliders 413 are slidably arranged on the front and back symmetric second guide rails 412. On the side of the electric slider 413 away from the corresponding second guide rail 412, an L-shaped connecting plate 414 is fixedly arranged. On the opposite sides of the front and back symmetric second guide rails 412, three second struts 415 are evenly fixedly arranged from left to right. A third guide rail 416 is fixedly arranged between the front and back symmetric second struts 415 through a first plate member. Electric sliders 417 are slidably arranged on the three third guide rails 416.

[0047] Please refer to Figure 8 and Figure 9, grinding assemblies 42 are provided on both the L-shaped connecting plate 414 and the electric slider three 417. The grinding assembly 42 includes a driving assembly 421 and a grinding wheel 423 mounted on the driving end of the driving assembly 421. A plurality of nozzles 422 are evenly installed on the lower side of the driving assembly 421 and located on the outer periphery of the grinding wheel 423. Among them, the driving assemblies 421 on the L-shaped connecting plate 414 and the driving assemblies 421 on the lower side of the electric slider three 417 are vertically distributed.

[0048] Please refer to Figure 7 and Figure 9 , the lifting assembly 43 includes a lifting platform 431 fixedly arranged on the upper side of the bottom plate 1 through a rod five. Pneumatic cylinders two 433 are symmetrically and fixedly arranged on the left and right sides of the lower side of the lifting platform 431. The telescopic ends of the pneumatic cylinders two 433 are provided with an adsorption assembly 32 that moves up and down. The fixing plate 321 in the adsorption assembly 32 is fixedly connected to the telescopic end of the pneumatic cylinder two 433. Two groups of guide rods 432 are slidably arranged on the left and right sides of the lifting platform 431. Each group is composed of four guide rods 432 fixedly arranged at the four corners of the lower surface of the corresponding fixing plate 321.

[0049] When grinding a pair of liquid crystal glasses synchronously, first, the two liquid crystal glasses to be ground are conveyed above the lifting platform 431 through the electric slider one 313. Then, the corresponding fixing plates 321 are driven to move upward by the two pneumatic cylinders two 433 until the vacuum suction cups 324 on the lower fixing plate 321 are attached to the lower surface of the corresponding liquid crystal glass and stably adsorb and position the liquid crystal glass. At this time, the adsorption positioning on the upper surfaces of the two liquid crystal glasses is released. Then, the two pneumatic cylinders two 433 synchronously drive the positioned liquid crystal glasses to move downward and reset until the four sides of the two liquid crystal glasses are respectively aligned with the corresponding grinding wheels 423 (as shown in Figure 8 ). At this time, not only the short sides on the same side of the two liquid crystal glasses are collinear, but also all the long sides are parallel and coplanar. Thus, when the two electric sliders two 413 move from one end to the other end of the corresponding guide rails two 412 respectively, the corresponding driving assemblies 421 and grinding wheels 423 can grind along the short sides on the same side of the two liquid crystal glasses. At the same time, when the three electric sliders three 417 move from one end to the other end of the corresponding guide rails three 416 respectively, the corresponding driving assemblies 421 and grinding wheels 423 can grind along the long sides of the corresponding liquid crystal glasses synchronously. Among them, 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 each edge of the liquid crystal glass, the moving speeds of the electric sliders two 413 and the electric sliders three 417 need to be the same.

[0050] Taking the liquid crystal glass panel corresponding to a liquid crystal display with a mainstream size in a 16:10 ratio as an example, assuming the grinding speed is 1 unit (i.e., 1 ratio), then it takes 16 seconds to grind the long side of the liquid crystal glass of this ratio and 10 seconds to grind the short side. Since when simultaneously grinding the four edges of a single liquid crystal glass, the total time required depends on the length of the long side, which is the time required for a single grinding wheel 423 to grind one side of the long side, so the total time required to grind a single liquid crystal glass of this ratio is 16 seconds, and the total time required to grind two liquid crystal glasses sequentially is 32 seconds; when using multiple sets of grinding equipment to simultaneously grind two liquid crystal glasses by increasing the cost, although it only takes 16 seconds to grind two liquid crystal glasses, at least 8 grinding wheels 423 need to work synchronously, and there will be a situation where the long-side grinding wheel 423 will still need to continue grinding for a long time while the short-side grinding wheel 423 stops working; when grinding the 16:10 liquid crystal glass by the grinding mechanism 4 set in the present invention, not only can two liquid crystal glasses be simultaneously ground with only 5 grinding wheels 423, but also the total time required for grinding is only slightly longer than the sum of the times required to grind the two short sides of the liquid crystal glass of this ratio, that is, slightly longer than 20 seconds; when grinding the liquid crystal glass panel corresponding to a liquid crystal display with a 21:9 ratio of the same mainstream size, the grinding mechanism 4 in the present invention takes 21 seconds to grind two liquid crystal panels of this ratio with 5 grinding wheels 423, while the existing method of grinding two liquid crystal glasses separately in sequence takes 42 seconds, and the method of synchronously grinding two liquid crystal glasses with 8 grinding wheels 423 takes 21 seconds. Therefore, according to the above conclusion, when batch-grinding liquid crystal glass, the grinding mechanism 4 in the present invention has obvious advantages in both the overall efficiency of liquid crystal glass grinding and the overall processing cost control.

[0051] When the two processed liquid crystal glasses are to be discharged synchronously, first move the electric slider 313 to the rearmost 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 frames 242. Then, drive the corresponding processed liquid crystal glasses to move upward through the air cylinder 433 until the upper surfaces of the processed liquid crystal glasses are in contact with and docked and adsorbed by the vacuum suction cups 324 on the upper corresponding fixing plates 321. At this time, the positioning adsorption on the lower side thereof can be released. At the same time, the two liquid crystal glasses to be polished are positioned and adsorbed by the vacuum suction cups 324 on the upper corresponding fixing plates 321 above the positioning frames 242. Finally, move the electric slider 313 to the front end, so as to move the two liquid crystal glasses to be polished above the lifting platform 431 for loading, and at the same time synchronously convey the two processed liquid crystal glasses forward for discharging. The above operation mode can realize the synchronous loading and discharging transportation of the liquid crystal glasses, thus greatly simplifying the operations of the overall loading and discharging transportation of the liquid crystal glasses, and further improving the overall transportation efficiency of the liquid crystal glasses and the overall polishing processing efficiency.
