Description

Technical Field

[0001] This invention belongs to the field of glass substrate production technology, and specifically relates to a self-weight grid-type shrink placement rack for glass substrates. Background Technology

[0002] Glass substrates are one of the key basic materials in the flat panel display industry.

[0003] The existing technology has the following problems: When glass substrates are produced and placed, they are mostly temporarily stored on A-frames. When a large number of glass substrates or glass substrates of different specifications need to be placed, a large number or multiple A-frames are required. This results in the glass substrates being placed in a messy or irregular manner. Therefore, there is an urgent need for a convenient glass substrate self-weight grid-type shrink placement rack to solve the above problems. Summary of the Invention

[0004] To address the problems mentioned in the background section, this invention provides a self-weight grid-type shrink-fit storage rack for glass substrates, which is convenient to use.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a self-weight grid-type shrink-fit placement rack for glass substrates, comprising a glass substrate placement end frame assembly, wherein the glass substrate placement end frame assembly is provided with multiple sets of independent glass substrate grid-type placement rack assemblies, the multiple sets of independent glass substrate grid-type placement rack assemblies forming a self-weight grid-type shrink-fit placement rack structure on the glass substrate placement end frame assembly, and the multiple sets of independent glass substrate grid-type placement rack assemblies being used to classify and place glass substrates of different specifications, and the multiple sets of independent glass substrate grid-type placement rack assemblies concentrating and gathering various types and quantities of glass substrates within the glass substrate placement end frame assembly;

[0006] The glass substrate placement end frame assembly includes a glass substrate placement end frame, with side protective frames fixedly installed on both sides of the glass substrate placement end frame. Multiple U-shaped support frames are fixedly installed on the inner wall of the glass substrate placement end frame. A bidirectional threaded screw is rotatably mounted on each U-shaped support frame. Internal threaded blocks are installed at both ends of the bidirectional threaded screw. Telescopic push arms are installed on both sides of each of the two internal threaded blocks. A first transmission pulley is fixedly mounted at the bottom end of the bidirectional threaded screw, and a transmission belt is mounted on the first transmission pulley. Retracting arms are rotatably mounted on both sides of the bottom of the U-shaped support frame. Retracting rotating rollers are rotatably mounted at the ends of the retracting arms. A tension spring is installed between the retracting arms and the glass substrate placement end frame.

[0007] Preferably, the glass substrate grid-type independent placement rack assembly includes a glass substrate placement rack and a supporting top frame. The bottom of the glass substrate placement rack is provided with a drive shaft, the drive shaft is provided with a spiral guide groove and a limiting end platform, and a push spring is sleeved on the top of the drive shaft. The bottom surface of the supporting top frame is fixedly provided with an end connecting vertical arm platform, a bottom supporting arc plate and a moving wheel. The center of the supporting top frame is provided with a top frame center groove. A guide sliding sleeve seat is rotatably provided on the bottom supporting arc plate through a bearing seat. The inner wall of the guide sliding sleeve seat is provided with a guide protrusion slide head, and a second transmission belt pulley is fixedly provided at the bottom of the guide sliding sleeve seat through the supporting vertical arm.

[0008] Preferably, the first conveyor belt pulley is located below the U-shaped support frame, and the bottom rod of the bidirectional threaded screw extends below the U-shaped support frame. Through the tension of the tension spring, the retracting rotating roller at the end of the retracting arm tightly abuts against the side of the conveyor belt.

[0009] Preferably, the drive shaft slides through the central groove of the top frame and the supporting top frame, the limiting end platform is located below the supporting top frame, the push spring is located above the supporting top frame, and the two ends of the push spring abut against the glass substrate placement frame and the supporting top frame, respectively.

[0010] Preferably, the drive shaft slides up and down within the guide sleeve base, and the guide convex slide head is inserted into the spiral guide groove on the drive shaft. Through the up and down sliding of the drive shaft and the cooperation of the guide convex slide head and the spiral guide groove, the guide sleeve base drives the second transmission belt pulley to rotate in both directions.

[0011] Preferably, the rear end of the telescopic push arm is configured as an open fork structure, and the front end of the telescopic push arm is configured as a closed structure. The front end of the telescopic push arm is rotatably connected to the side of the end connecting vertical arm platform via a shaft pin. The rear end of the telescopic push arm is rotatably connected to two internal threaded seats at both ends of the bidirectional threaded screw via a shaft pin. The telescopic push arm serves as a push arm structure that extends and retracts on the glass substrate grid-type independent placement rack assembly.

[0012] Preferably, the second transmission pulley at the bottom of the guide sleeve base forms a drive structure that drives the first transmission pulley to rotate, and the transmission belt is wound between the first transmission pulley and the second transmission pulley.

[0013] Preferably, the glass substrate placement rack is configured with an inclined structure. The more glass substrates of the same type placed on the glass substrate placement rack, the greater the force of the telescopic push arm retracting backward. The more glass substrates placed on the glass substrate placement rack are removed, the greater the force of the telescopic push arm extending forward.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: When the present invention is used, multiple sets of glass substrate grid-type independent placement rack assemblies form a self-weight grid-type retractable placement rack structure on the glass substrate placement end frame assembly. The working principle is as follows: the telescopic push arm serves as the push arm structure for the glass substrate grid-type independent placement rack assembly to extend and retract on the glass substrate placement end frame assembly; the drive shaft slides up and down within the guide sleeve base; the guide convex slide head is inserted into the spiral guide groove on the drive shaft; through the up and down sliding of the drive shaft and the cooperation of the guide convex slide head and the spiral guide groove, the guide sleeve base drives the second transmission belt pulley to perform a bidirectional rotation action; the second transmission belt pulley at the bottom of the guide sleeve base forms... The drive structure that drives the first conveyor pulley to rotate includes a conveyor belt wound between the first and second conveyor pulleys. The glass substrate placement rack is designed with an inclined structure. The more glass substrates of the same type placed on the glass substrate placement rack, the greater the gravity on the rack, which will press the rack down. At this time, through the up-and-down sliding of the drive shaft and the cooperation of the guide convex slide head and the spiral guide groove, the guide sleeve seat drives the second conveyor pulley to rotate. Through the action of the conveyor belt, the first conveyor pulley will rotate simultaneously. At this time, the two internal threaded blocks at both ends of the bidirectional threaded screw move away from each other, that is, the internal threaded blocks move towards the end of the bidirectional threaded screw. At this point, the force of the telescopic push arm retracting backward increases, which is to collect the glass substrates during placement. Multiple sets of independently arranged glass substrate racks gather various types and quantities of glass substrates into the glass substrate placement end frame assembly. Simultaneously, during material retrieval, as a glass substrate is removed from the rack, the weight exerted by the substrate on the rack decreases. Then, the above actions reverse, and the force of the telescopic push arm extending forward increases, pushing the independently arranged glass substrate rack assembly off the glass substrate placement end frame assembly. In this way, multiple sets of independently arranged glass substrate racks are used to classify and place glass substrates of different specifications. The grid-type independent placement rack assembly gathers various types and quantities of glass substrates into the glass substrate placement end frame assembly. Simultaneously, through this structure, as more glass substrates are placed, the grid-type independent placement rack assembly automatically retracts into the glass substrate placement end frame assembly; conversely, as fewer glass substrates are placed, the grid-type independent placement rack assembly automatically pops out from within the glass substrate placement end frame assembly. This indicates to the user which set of the grid-type independent placement rack assembly has no substrates, or, when placing glass substrates of the same specification and type, the amount of substrates on each set can be discerned by the amount of substrates removed during the use of glass substrates.

The bottom rod of the bidirectional threaded screw 104 extends to the bottom of the U-shaped support frame 102. Through the tension of the tension spring 105, the retracting rotating roller 107 at the end of the retracting arm 106 tightly abuts against the side of the conveyor belt 109.

A push spring 204 is sleeved on the top of the drive shaft 202. The bottom surface of the supporting top frame 205 is fixedly provided with an end-connecting vertical arm platform 214, a bottom supporting arc plate 208, and a moving wheel 207. A top frame is located at the center of the supporting top frame 205. A guide sleeve seat 210 is rotatably mounted on the bottom support arc plate 208 via a bearing seat in the central slide groove 206. A guide protruding slide head 209 is provided on the inner wall of the guide sleeve seat 210.

The drive shaft 202 slides up and down in the guide sleeve seat 210. The guide convex slide head 209 is inserted into the spiral guide groove 203 on the drive shaft 202. Through the up and down sliding of the drive shaft 202 and the cooperation of the guide convex slide head 209 and the spiral guide groove 203, the guide sleeve seat 210 drives the second transmission pulley 211 to rotate in both directions. The second transmission pulley 211 at the bottom of the guide sleeve seat 210 forms a drive structure that drives the first transmission pulley 110 to rotate. The transmission belt 109 is wound between the first transmission pulley 110 and the second transmission pulley 211. The glass substrate placement rack 201 is set with an inclined structure. The more glass substrates of the same type are placed on the glass substrate placement rack 201, the greater the force of the telescopic push arm 108 retracting backward. The more glass substrates placed on the glass substrate placement rack 201 are taken out, the greater the force of the telescopic push arm 108 extending forward.

[0026] Working principle and usage process of the present invention: When the present invention is used, multiple sets of glass substrate grid-type independent placement rack assemblies 200 form a self-weight grid-type retractable placement rack structure on the glass substrate placement end frame assembly 100. The working principle is as follows: the telescopic push arm 108 serves as the push arm structure for the glass substrate grid-type independent placement rack assembly 200 to extend and retract on the glass substrate placement end frame assembly 100. The drive shaft 202 slides up and down within the guide sleeve seat 210. The guide convex slide head 209 is inserted into the spiral guide groove 203 on the drive shaft 202. Through the up and down sliding of the drive shaft 202 and the cooperation of the guide convex slide head 209 and the spiral guide groove 203, the guide sleeve seat 210 drives the second transmission belt pulley 211 to rotate in both directions. The second transmission pulley 211 at the bottom of the sliding sleeve base 210 forms a drive structure that drives the first transmission pulley 110 to rotate. The transmission belt 109 is wound between the first transmission pulley 110 and the second transmission pulley 211. The glass substrate placement rack 201 is set with an inclined structure. The more glass substrates of the same type placed on the glass substrate placement rack 201, the greater the gravity on the glass substrate placement rack 201. At this time, the glass substrate placement rack 201 will be pressed down. At this time, through the up and down sliding of the drive shaft 202 and the cooperation of the guide convex slide head 209 and the spiral guide slide groove 203, the guide sliding sleeve base 210 drives the second transmission pulley 211 to rotate. Through the action of the transmission belt 109, the first transmission pulley 110 will rotate at the same time. At this time, the two internal threaded seats 103 at both ends of the bidirectional threaded screw 104 move away from each other, that is, the internal threaded seats 103 move towards the end of the bidirectional threaded screw 104. At this time, the force of the telescopic push arm 108 retracting backward increases, that is, the glass substrate is stored when it is placed. At this time, multiple sets of glass substrate grid-type independent placement rack assemblies 200 gather various types and quantities of glass substrates into the glass substrate placement end rack assembly 100. At the same time, when the glass substrate is taken out during material retrieval, the weight of the glass substrate on the glass substrate placement rack 201 decreases. At this time, the above actions are reversed. At this time, the force of the telescopic push arm 108 extending forward is greater, and the glass substrate grid-type independent placement rack assembly 200 moves from the glass substrate placement end rack. The components are pushed out from the assembly 100. In this way, multiple sets of glass substrate grid-type independent placement rack assemblies 200 are used to classify and place glass substrates of different specifications. These multiple sets of glass substrate grid-type independent placement rack assemblies 200 gather various types and quantities of glass substrates into the glass substrate placement end frame assembly 100. Simultaneously, through this structure, as more glass substrates are placed, the glass substrate grid-type independent placement rack assemblies 200 automatically retract into the glass substrate placement end frame assembly 100; when fewer glass substrates are placed, the glass substrate grid-type independent placement rack assemblies 200 automatically pop out from the glass substrate placement end frame assembly 100, indicating to the user which set of glass substrate grid-type independent placement rack assemblies 200 is empty, or which requires the placement of glass substrates of the same specification and type.By observing the amount of material ejected, one can determine the quantity of substrates placed on each of the individual glass substrate grid-type placement rack assemblies 200, or the quantity of substrates removed during the use of glass substrates.

[0027] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
