Description

Technical Field

[0001] This utility model relates to the technical field of glass substrate processing equipment, and in particular to a glass substrate handling arm structure. Background Technology

[0002] Glass substrates are one of the key basic materials in the flat panel display industry. A transparent conductive layer of In2O3 or SnO2, namely ITO film, is deposited on the surface. Transparent conductive patterns are formed by photolithography. These patterns are composed of pixel patterns and external lead patterns. Therefore, the external leads cannot be soldered in the traditional way and can only be connected by conductive rubber strips or conductive tapes.

[0003] Traditional glass handling suction cups have a fixed stroke. When the glass is too large, the suction area is insufficient, which can easily generate stress and cause damage during handling. In severe cases, it may damage the glass substrate and render it unusable. Utility Model Content

[0041] To facilitate understanding by those skilled in the art, the present invention will be further described below in conjunction with embodiments and accompanying drawings. Specific embodiments of the present invention will be described below. It should be noted that, in order to provide a concise description of these embodiments, this specification cannot provide a detailed description of all features of the actual embodiments.

[0042] refer to Figures 1 to 7 As shown, this utility model provides a glass substrate transport arm structure, including a support base 1 and at least two transport arms 2 connected to the support base 1. Each transport arm 2 is provided with a support portion 3. The support portion 3 is equipped with a detection switch 31 for detecting the positioning of the glass substrate body. A first adsorption member 32 and a second adsorption member 33 are respectively installed at both ends of the support portion 3. A third adsorption member 300 is installed on at least one side of the transport arm 2. The third adsorption member 300 is arranged at the same height as the first adsorption member 32 and the second adsorption member 33.

[0043] refer to Figure 1 , 2 As shown, in practical applications, the support base 1 is connected to an external device. The external device drives the support base 1 to move and smoothly grasp the glass substrate. The external device is a robotic arm or industrial robot to achieve smooth transfer of the glass substrate. The detection switch 31 is a positioning detection switch 31. When the glass substrate is accurately placed on the support 3, the detection switch 31 confirms that the glass substrate is in the preset position, thereby accurately determining the position of the glass substrate. The glass substrate is adsorbed by the first adsorption member 32, the second adsorption member 33, and the third adsorption member 300 to achieve precise positioning of the glass substrate. Specifically, the third adsorption member 300 can be installed on both sides of the transport arm 2 to increase the adsorption area of ​​the glass substrate and improve adsorption stability. The third adsorption member 300 can also be installed on a single side of the transport arm 2, and the third adsorption member 300 can be located on different sides of the transport arm 2 to meet the transport needs of glass substrates of different sizes, increase the adsorption area of ​​the glass substrate, prevent the glass substrate from falling off, thereby preventing damage to the glass substrate during transport and ensuring the structural integrity of the glass substrate.

[0044] refer to Figure 1 , 2As shown in this embodiment, at least two third adsorption elements 300 are installed on one side of the transport arm 2 to increase the adsorption area on the glass substrate and improve adsorption stability.

[0045] refer to Figure 2 As shown, in this embodiment, a first cable clamp 4 is installed on the transport arm 2. The first cable clamp 4 and the third suction member 300 are located on the same side of the transport arm 2. The first cable clamp 4 is located between two adjacent third suction members 300. The first cable clamp 4 is provided with a receiving channel 41 for the cable on the third suction member 300 to pass through. The two ends of the receiving channel 41 correspond to the third suction member 300 respectively. (Reference) Figure 1 , 2 As shown, in practical applications, the cables required for the installation of the third adsorption component 300 do not pass through the inside of the transport arm 2. The cables on the third adsorption component 300 are threaded through the receiving channel 41. The receiving channel 41 accurately positions the cables on the third adsorption component 300, which helps to reduce mechanical vibration caused by cable swinging or tangling. The stable cable layout can avoid the influence of electromagnetic interference in the vacuum environment on the drive signal.

[0046] refer to Figure 1 , 2 As shown, in this embodiment, a second cable clamp 5 is installed on the transport arm 2. The second cable clamp 5 and the third adsorption member 300 are located on the same side of the transport arm 2. The second cable clamp 5 is provided with a receiving channel 51 for the cable on the third adsorption member 300 to pass through. The receiving channel 51 accurately positions the cable of the third adsorption member 300 between the transport arm 2 and the support base 1, which helps to reduce mechanical vibration caused by cable swinging or tangling. The stable cable layout can avoid the influence of electromagnetic interference in the vacuum environment on the drive signal.

[0047] refer to Figure 3 As shown, in this embodiment, the first adsorption member 32 includes an adsorption seat 321, an adsorption hole 322 disposed on the adsorption seat 321, and a sealing gasket 323. The support part 3 is provided with a connecting hole 32. The adsorption seat 321 is installed on the support part 3. The connecting hole 32 communicates with the adsorption hole 322. The sealing gasket 323 seals the connection between the connecting hole 32 and the adsorption hole 322. In practical applications, the connecting hole 32 is connected to a vacuum generator, which is a vacuum pump. When the glass substrate body is accurately placed on the support part 3, the vacuum pump generates a negative pressure in the connecting hole 32 and the adsorption hole 322, thereby successfully adsorbing the glass substrate body. The sealing gasket 323 prevents gas leakage along the connection between the connecting hole 32 and the adsorption hole 322, ensuring the airtightness of the structure. Specifically, the first adsorption member 32 and the second adsorption member 33 have the same structure, which facilitates the successful adsorption of the glass substrate body and ensures the airtightness of the structure.

[0048] refer to Figure 1 , 3 As shown, in this embodiment, the support part 3 is provided with an installation groove 301, and the adsorption seat 321 is installed in the installation groove 301. The structure is compact and saves space. A buffer washer 320 is installed on the top of the adsorption seat 321. The top of the buffer washer 320 is higher than the top of the adsorption hole 322, so that when the glass substrate is adsorbed by negative pressure, the glass substrate body is in contact with the buffer washer 320, which helps to reduce the impact and vibration of external force on the glass substrate body and protect the glass substrate body from damage. By surrounding the top of the adsorption hole 322 with the buffer washer 320, it is easy to form a sealed space between the glass substrate body and the adsorption hole 322.

[0049] refer to Figure 2 , 4 As shown, in this embodiment, the conveying arm 2 is provided with a gas supply channel 21, which is connected to the connecting hole 32. The third adsorption element 300 is connected to an adsorption tube, which is connected to the gas supply channel 21. The support base 1 is provided with an installation cavity 101, which is connected to the gas supply channel 21. In actual application, a negative pressure is connected to the installation cavity 101. The negative pressure can be smoothly filled into the connecting hole 32, the adsorption tube and the third adsorption element 300 through the gas supply channel 21, thereby successfully adsorbing the glass substrate body.

[0050] refer to Figure 5 , 6 As shown, in this embodiment, the first wire clamp 4 includes a wire clamp box 401, mounting portions 402 disposed at both ends of the wire clamp box 401, and a locking member 403. The locking member 403 is used to lock the mounting portion 402 to the transport arm 2. The accommodating channel 41 includes a straight section and an extended section. The straight section passes through both ends of the wire clamp box 401, and the extended section is connected to one side of the straight section. The extended section is located between the mounting portions 402. In actual application, the locking member 403 uses screws to smoothly install or remove the wire clamp box 401. The accommodating channel 41 is configured with a straight section and an extended section. Please refer to the attached diagram. Figure 6 In the diagram, the section above the dotted line is the straight section, and the section below the dotted line is the extension section. The straight section meets the cable transmission requirements, facilitates normal cable connection, and meets installation and communication needs. The extension section accommodates the foldable parts of the cable, saving space and making cable management easier. Specifically, the first cable clamp 4 and the second cable clamp 5 have the same structure, but the length of the first cable clamp 4 is shorter than the length of the second cable clamp 5, so that the first cable clamp 4 and the second cable clamp 5 can meet different cable accommodating needs, and facilitate the installation and folding of the corresponding cable by the second cable clamp 5.

[0051] refer to Figure 1 , 7As shown, in this embodiment, both the first adsorption element 32 and the second adsorption element 33 are connected to an adsorption connector 6. The adsorption connector 6 is installed in the gas delivery channel 21, and an isolation gasket 61 is connected between the adsorption connector 6 and the gas delivery channel 21. One end of the adsorption connector 6 is connected to the connecting hole 32, and the other end of the adsorption connector 6 is connected to the negative pressure generating device through a pipeline to ensure smooth delivery of negative pressure. The adsorption connector 6 is provided with an assembly groove 62, and the transport arm 2 is equipped with an assembly block 7. Part of the assembly block 7 is inserted into the assembly groove 62. By providing adsorption connectors 6 at the connection between the first adsorption element 32 and the second adsorption element 33, when maintaining and expanding the system, only the damaged or adjusted adsorption connector 6 needs to be replaced, without disassembling the entire gas delivery channel 21 system, which facilitates maintenance and reduces maintenance time. The cooperation between the assembly groove 62 and the assembly block 7 facilitates the positioning of the adsorption connector 6 during installation, improves installation efficiency, and facilitates quick installation or removal of the adsorption connector 6.
