Description

Technical Field

[0001] The present invention belongs to the technical field of glass substrate production, and particularly relates to a self-pressure-relieving handling arm mechanism for glass substrates. Background Art

[0002] The glass substrate is one of the key basic materials in the flat panel display industry. A layer of In2O3 or SnO2 transparent conductive layer, i.e., ITO film layer, is vapor-deposited on the surface. Transparent conductive patterns are made by photolithography processing. These patterns are composed of pixel patterns and outer lead patterns. Therefore, traditional soldering cannot be performed on the outer leads, and they can only be connected through conductive rubber strips or conductive tapes, etc. If scratched, cut, or corroded, the device will be scrapped.

[0003] The prior art has the following problems: When handling glass substrates, most of the existing devices use clamping or suction cup methods, which are prone to causing damage such as indentations. Therefore, there is an urgent need for a glass substrate handling structure different from the traditional one to solve the above problems. Summary of the Invention

[0004] To solve the problems raised in the above background art, the present invention provides a self-pressure-relieving handling arm mechanism for glass substrates, which has the characteristics of convenient handling and use.

The airbag-type glass substrate handling arm assembly is arranged at the end of a telescopic glass substrate handling arm assembly. A set of airbag-type glass substrate handling arm assemblies are arranged at both ends of the telescopic glass substrate handling arm assembly. The airbag-type glass substrate handling arm assembly forms an airbag-type clamping structure during glass substrate handling at the end of the telescopic glass substrate handling arm assembly. The telescopic glass substrate handling arm assembly forms an extension or contraction structure of the clamping structure above the airbag-type glass substrate handling arm assembly.

An installation top seat arm platform is fixedly arranged on the top of the top U-shaped frame. Second internal threaded seat blocks are threadedly arranged at both ends of the second bidirectional threaded screw. A glass substrate handling telescopic arm is arranged between the two second internal threaded seat blocks.

[0008] Preferably, a clamping contact airbag structure for the glass substrate during handling is formed between the glass substrate clamping airbags on the T-shaped seat arm frames at both ends of the first bidirectional threaded screw. By the approach or separation of the two first internal threaded seat blocks, the handling and clamping or release of the clamping of the glass substrate between the two opposed glass substrate clamping airbags are realized.

[0009] Preferably, in the initial state, the glass substrate clamping airbag is communicated with an external pressurized air supply device through an airbag inlet pipe, a one-way valve is arranged inside the airbag inlet pipe, and the excessive air pressure of the glass substrate clamping airbag is discharged through an air pipe air leakage groove on the airbag discharge pipe.

[0010] Preferably, an annular ring platform is arranged inside the airbag discharge pipe, the annular ring platform is located at the bottom of the air pipe air leakage groove, the guiding through sliding rod is slidably connected with the airbag discharge pipe through a guiding through sliding groove, and both ends of the sealing top pushing spring respectively abut against the sealing piston and the top of the airbag discharge pipe. By the top pushing of the sealing top pushing spring, the sealing piston always presses and seals against the bottom annular ring platform inside the airbag discharge pipe.

[0011] Preferably, a glass substrate airbag clamping structure is formed between two opposed glass substrate clamping airbags on a set of the airbag type glass substrate handling arm assemblies. When the two glass substrate clamping airbags clamp the glass substrate, the excessive clamping air pressure of the glass substrate clamping airbag is discharged through the airbag discharge pipe. Through the protection of the airbag discharge pipe, a glass substrate handling and clamping structure with a rated air pressure is formed between the two glass substrate clamping airbags.

[0012] Preferably, a complete set of glass substrate self-relieving pressure handling arm unit is formed between two sets of the airbag type glass substrate handling arm assemblies and a set of glass substrate telescopic handling arm assemblies.

The second bidirectional threaded screw is driven by the second drive motor to rotate bidirectionally. At this time, the two second internally threaded seat blocks move closer to or away from each other. At this time, the glass substrate handling telescopic arm is in an extended or contracted arm structure.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: When the present invention is in use, a complete set of glass substrate self-pressure-relieving handling arm units is formed between the two sets of airbag-type glass substrate handling arm assemblies and one set of glass substrate telescopic handling arm assemblies. Through the telescoping of the glass substrate telescopic handling arm assembly, a glass substrate handling arm structure with adjustable spacing is formed between the two sets of airbag-type glass substrate handling arm assemblies. An airbag exhaust pipe is provided at the glass substrate clamping airbag of the airbag-type glass substrate handling arm assembly. At this time, an annular ring platform is provided inside the airbag exhaust pipe. The annular ring platform is located at the bottom of the air pipe exhaust groove. The guiding through sliding rod is slidably connected to the airbag exhaust pipe through the guiding through chute. The two ends of the sealing pushing spring respectively abut against the sealing piston and the top of the airbag exhaust pipe. Through the pushing of the sealing pushing spring, the sealing piston always presses and seals against the bottom annular ring platform inside the airbag exhaust pipe. Through this method, the protection of the air pressure inside the glass substrate clamping airbag is realized. During actual use, in the initial state, the glass substrate clamping airbag is communicated with an external pressurized air supply device through the airbag inlet pipe. A one-way valve is provided inside the airbag inlet pipe. The excessive air pressure of the glass substrate clamping airbag is discharged through the air pipe exhaust groove on the airbag exhaust pipe. Through this method, the air pressure inside the glass substrate clamping airbag is within a safe range. When the glass substrate is clamped and handled, a clamping contact airbag structure for handling the glass substrate is formed between the glass substrate clamping airbags on the T-shaped seat arm frames at both ends of the first bidirectional threaded screw. Through the approach or separation of the two first internally threaded seat blocks, the handling and clamping or release of the clamping of the glass substrate between the two opposing glass substrate clamping airbags is realized. At this time, when the two glass substrate clamping airbags are in contact with the glass substrate, the excessive clamping air pressure of the glass substrate clamping airbag is discharged through the airbag exhaust pipe. Through the protection of the airbag exhaust pipe, a glass substrate handling and clamping structure with a rated air pressure is formed between the two glass substrate clamping airbags. Through this method, it is avoided that the pressure between the two glass substrate clamping airbags and the glass substrate is too large. When the clamping force is too large, at this time, the pressure of the glass substrate clamping airbag increases. When it exceeds the safety value, the excessive air pressure is discharged through the airbag exhaust pipe. Through this method, the clamping and fixing method during glass substrate handling is changed, and the traditional handling and fixing method that is prone to producing indentations or adsorption marks is changed.

Detailed implementation manners

[0021] 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-5, the present invention provides the following technical solution: A self-relieving handling arm mechanism for a glass substrate, including an airbag-type glass substrate handling arm assembly 100. The airbag-type glass substrate handling arm assembly 100 is arranged at the end of the telescopic glass substrate handling arm assembly 200. A set of airbag-type glass substrate handling arm assemblies 100 are arranged at both ends of the telescopic glass substrate handling arm assembly 200. The airbag-type glass substrate handling arm assembly 100 forms an airbag-type clamping structure during the handling of the glass substrate at the end of the telescopic glass substrate handling arm assembly 200. The telescopic glass substrate handling arm assembly 200 forms an extension or contraction structure of the clamping structure above the airbag-type glass substrate handling arm assembly 100. A complete set of self-relieving handling arm units for the glass substrate is formed between the two sets of airbag-type glass substrate handling arm assemblies 100 and a set of telescopic glass substrate handling arm assemblies 200. Through the expansion and contraction of the telescopic glass substrate handling arm assembly 200, a glass substrate handling arm structure with adjustable spacing is formed between the two sets of airbag-type glass substrate handling arm assemblies 100;

[0023] The airbag type glass substrate handling arm assembly 100 includes a U-shaped side frame 101. Inside the U-shaped side frame 101, a first double-threaded screw rod 102 is rotatably arranged. And at the bottom of the U-shaped side frame 101, a first driving motor 104 is fixedly arranged. At both ends of the first double-threaded screw rod 102, first internal thread seat blocks 103 are threadedly arranged. On the first internal thread seat blocks 103, T-shaped seat arm frames 105 are fixedly arranged. On the inner side surface of the T-shaped seat arm frames 105, glass substrate clamping airbags 106 are arranged. And on the outer side surface of the T-shaped seat arm frames 105, airbag exhaust pipes 108 are fixedly arranged. One end of the glass substrate clamping airbag 106 is provided with an airbag inlet pipe 107. On the airbag exhaust pipe 108, an air pipe air release groove 109 and a guiding through chute 110 are arranged. And inside the airbag exhaust pipe 108, a guiding through sliding rod 111 is slidably arranged. At the top of the guiding through sliding rod 111, a limiting ball head 112 is fixedly arranged. And at the bottom of the guiding through sliding rod 111, a sealing piston 113 is fixedly arranged. A sealing push spring 114 is sleeved on the guiding through sliding rod 111. Between the glass substrate clamping airbags 106 on the T-shaped seat arm frames 105 at both ends of the first double-threaded screw rod 102, a clamping contact airbag structure for handling the glass substrate is formed. By the approach or separation of the two first internal thread seat blocks 103, the handling and clamping or release of the clamping of the glass substrate between the two opposed glass substrate clamping airbags 106 are realized. In the initial state, the glass substrate clamping airbag 106 is communicated with an external pressurized air supply device through the airbag inlet pipe 107. A one-way valve is arranged inside the airbag inlet pipe 107. The excessive air pressure of the glass substrate clamping airbag 106 is discharged through the air pipe air release groove 109 on the airbag exhaust pipe 108. An annular ring platform is arranged inside the airbag exhaust pipe 108. The annular ring platform is located at the bottom of the air pipe air release groove 109. The guiding through sliding rod 111 is slidably connected with the airbag exhaust pipe 108 through the guiding through chute 110. The two ends of the sealing push spring 114 respectively abut against the sealing piston 113 and the top of the airbag exhaust pipe 108. Through the pushing of the sealing push spring 114, the sealing piston 113 always presses and seals on the bottom annular ring platform inside the airbag exhaust pipe 108. Between the two opposed glass substrate clamping airbags 106 on a set of airbag type glass substrate handling arm assemblies 100, a glass substrate airbag clamping structure is formed. When the two glass substrate clamping airbags 106 clamp the glass substrate, the excessive clamping air pressure of the glass substrate clamping airbag 106 is discharged through the airbag exhaust pipe 108. Through the protection of the airbag exhaust pipe 108, a glass substrate handling and clamping structure with a rated air pressure is formed between the two glass substrate clamping airbags 106;

[0024] The glass substrate telescopic handling arm assembly 200 includes a top U-shaped frame 201. A second bidirectional threaded screw 202 is rotatably arranged inside the top U-shaped frame 201, and a second driving motor 205 is arranged at one end of the top U-shaped frame 201. An installation top seat arm platform 203 is fixedly arranged at the top of the top U-shaped frame 201. Second internal threaded seat blocks 204 are threadedly arranged at both ends of the second bidirectional threaded screw 202. A glass substrate handling telescopic arm 206 is arranged between the two second internal threaded seat blocks 204. The top of the glass substrate telescopic handling arm assembly 200 is fixed on the reserved position of the robotic arm through fastening bolts and the installation top seat arm platform 203. By driving the second bidirectional threaded screw 202 to rotate bidirectionally through the second driving motor 205, at this time, the two second internal threaded seat blocks 204 are in the actions of approaching or moving away from each other. At this time, the glass substrate handling telescopic arm 206 is in an extended or contracted arm structure.

[0025] Working principle and usage process of the present invention: When the present invention is in use, a complete set of self-pressure-relief handling arm unit for glass substrates is formed between two sets of airbag-type glass substrate handling arm assemblies 100 and one set of telescopic glass substrate handling arm assembly 200. Through the telescoping of the telescopic glass substrate handling arm assembly 200, a glass substrate handling arm structure with adjustable spacing is formed between the two sets of airbag-type glass substrate handling arm assemblies 100. An airbag air release pipe 108 is provided at the glass substrate clamping airbag 106 of the airbag-type glass substrate handling arm assembly 100. At this time, an annular ring platform is provided inside the airbag air release pipe 108, and the annular ring platform is located at the bottom of the air pipe air release groove 109. The guiding through sliding rod 111 is slidably connected to the airbag air release pipe 108 through the guiding through chute 110. The two ends of the sealing push spring 114 respectively abut against the sealing piston 113 and the top of the airbag air release pipe 108. Through the pushing of the sealing push spring 114, the sealing piston 113 always presses and seals against the bottom annular ring platform inside the airbag air release pipe 108. In this way, the protection of the air pressure inside the glass substrate clamping airbag 106 is realized. During actual use, in the initial state, the glass substrate clamping airbag 106 is communicated with an external pressurized air supply device through the airbag inlet pipe 107. A one-way valve is provided inside the airbag inlet pipe 107. The excessive air pressure of the glass substrate clamping airbag 106 is discharged through the air pipe air release groove 109 on the airbag air release pipe 108. In this way, the air pressure inside the glass substrate clamping airbag 106 is within a safe range. When clamping and handling the glass substrate, a clamping contact airbag structure for handling the glass substrate is formed between the glass substrate clamping airbags 106 on the T-shaped seat arm brackets 105 at both ends of the first double-threaded screw rod 102. By approaching or separating the two first internal thread seat blocks 103, the handling and clamping or release of the clamping of the glass substrate between the two opposing glass substrate clamping airbags 106 are realized. At this time, when the two glass substrate clamping airbags 106 are in contact with the glass substrate, the excessive clamping air pressure of the glass substrate clamping airbag 106 is discharged through the airbag air release pipe 108. Through the protection of the airbag air release pipe 108, a glass substrate handling and clamping structure with a rated air pressure is formed between the two glass substrate clamping airbags 106. In this way, it is avoided that the pressure between the two glass substrate clamping airbags 106 and the glass substrate is too large. When the clamping force is too large, at this time, the pressure of the glass substrate clamping airbag 106 increases. When it exceeds the safety value, the excessive air pressure is discharged through the airbag air release pipe 108. In this way, the clamping and fixing method during glass substrate handling is changed, and the traditional handling and fixing method that is prone to generating indentations or adsorption marks is changed.
