[0028] Example 1

[0029] like Figure 1 As shown, an embodiment provides a dustproof wiring device 1, which includes: a nut mounting flange 11, a first flexible magnetic strip group 12, a threading strip assembly 13, a steel strip assembly 14, a second flexible magnetic strip group, a guide block 15, a cover plate 16 and an ARM arm flange seat 2.

[0030] The nut mounting flange 11 is connected to the linear guide rail 5 outside the column 3 of the robot to ensure the stability of the device.

[0031] The first flexible magnetic stripe group 12 is attached to the outer side of the column 3, and its two ends are respectively fixed to the upper cover plate 31 and the lower base plate 32 of the column 3 to achieve stable double-end fixation. The middle part of the first flexible magnetic stripe group 12 is closely connected to the outer side of the nut mounting flange 11 to enhance the compactness of the overall structure.

[0032] Preferably, the first flexible magnetic strip group 12 consists of two flexible magnetic strips arranged in parallel.

[0033] The strapping strip assembly 13 is arranged on the outside of the first flexible magnetic strip group 12 and is connected to the nut mounting flange 11 through screws.

[0034] In this embodiment, if Figure 2 , 3As shown in Figure 4, the strip assembly 13 includes two parallel vertical plates 131, a connecting plate 132 and two symmetrically arranged inclined plates 133. The connecting plate 132 is located between the two vertical plates 131. The two inclined plates 133 are respectively connected to the two ends of the connecting plate 132. A receiving groove is formed between the inclined plate 133 and the two vertical plates 131. A first wiring hole 134 is provided on the side of one vertical plate 131. A second wiring hole 135 is provided on the side of the connecting plate 132 close to the column 3. The second wiring hole 135 is connected to the first wiring hole 134 through an L-shaped wiring cavity, which facilitates the orderly threading of the cable 4. The wire harness is collected from the ARM of the robot and passes through the first wiring hole 134 and the second wiring hole 135 of the strip assembly 13 to enter the interior of the column 3. Moreover, when the robot column 3 moves up and down, the steel belt assembly 14 is always in contact with the first flexible magnetic strip group 12 to effectively prevent the dust generated inside the column 3 from affecting the cleanliness of the glass panel.

[0035] Preferably, the first wiring hole 134 and the second wiring hole 135 are square in shape, and both the first wiring hole 134 and the second wiring hole 135 are rounded to reduce cable wear and increase service life.

[0036] Further preferably, the number of the first wiring hole 134 and the number of the second wiring hole 135 are respectively set to ≥ 2. In this embodiment, the number of the first wiring hole 134 and the number of the second wiring hole 135 are respectively set to 2.

[0037] The steel belt assembly 14 includes a first steel belt 141 and a second steel belt 142. The first steel belt 141 covers the outside of the connecting plate 132 and the inclined plate 133, and the second steel belt 142 covers the outside of the first flexible magnetic strip. The first steel belt 141 is connected to the second steel belt 142. In this embodiment, the second steel belt 142 is attached to the middle of the two parallel flexible magnetic strips. The upper and lower ends of the steel belt assembly 14 are respectively fixed to the upper cover plate 31 and the lower base plate 32 of the column 3 by a pressing block 143, and the upper and lower ends of the steel belt assembly 14 are respectively connected to the pressing block 143 by screws.

[0038] The second flexible magnetic stripe group is attached to the outside of the first steel strip 141. The second flexible magnetic stripe group and the first flexible magnetic stripe group 12 are mutually attracted by magnetic force, so that the strip threading assembly 13 remains stable.

[0039] The guide block 15 is installed in the receiving groove of the strip and is located outside the second flexible magnetic strip group. The upper and lower ends of the strip assembly 13 covered by the first steel strip 141 are pressed by the guide block 15.

[0040] The cover plate 16 is connected to the two vertical plates 131 respectively by screws. The outer side of the belt strip assembly 13 is sealed with the cover plate 16.

[0041] The combined structure of the first flexible magnetic stripe group 12, the belt threading strip assembly 13, the steel strip assembly 14, the second flexible magnetic stripe group and the cover plate 16 forms an integrated dust-proof and wiring system, avoiding the problem of dust adhesion caused by gaps caused by lifting in the split structure.

[0042] like Figure 5 As shown, the ARM arm flange seat 2 is connected to the cover plate 16, and a third wiring hole 21 and a fourth wiring hole 22 are provided in the ARM arm flange seat 2. The third wiring hole 21 and the fourth wiring hole 22 are respectively used for the cable layout of the ARM upper arm and the lower arm, so as to achieve more efficient and orderly cable management.

[0043] Preferably, the third wiring hole 21 and the fourth wiring hole 22 are circular to facilitate threading.

[0044] The dustproof wiring device 1 is easy to install, and the first flexible magnetic strip group 12, the steel belt assembly 14 and other components are installed on the outside of the column 3, which is convenient for subsequent disassembly and maintenance. By adopting the magnetic dustproof method of the flexible magnetic strip group and the steel belt assembly 14, combined with the optimized design of the threading strip structure to realize the threading function, low-cost and efficient dustproof and wiring effects are achieved.

[0045] Example 2

[0046] like Figure 6 and 7 As shown, Example 2 shows a column-type display panel handling robot designed for clean level 10 environment, which is mainly used for handling glass panels. The robot structure includes a movable column 33, a fixed column 34 and an ARM arm flange seat 2, wherein the ARM arm flange seat 2 is specially designed for installing the ARM arm and is flexibly installed on the movable column 33 through a linear guide rail 5; and the movable column 33 is also movably connected with the fixed column 34 by means of a linear guide rail 5. In order to enhance the dustproof performance, the dustproof wiring device 1 described in Example 1 is provided between the movable column 33 and the ARM arm flange seat 2, and between the fixed column 34 and the movable column 33.

[0047] The movable column 33 and the fixed column 34 are both designed as a vertical hollow structure to facilitate the cable to pass through. Specifically, the side of the movable column 33 is provided with a first threading hole 331, and the side of the fixed column 34 is provided with a second threading hole 341.

[0048] like Figure 8It is shown in detail that the wiring path of the cable 4 is ingeniously designed: first, it passes through the hollow area of ​​the fixed column 34, is led out to the outside through the second threading hole 341, and is arranged in order along the cable drag chain. Then, the cable cleverly enters the hollow part of the movable column 33 through the dust-proof wiring device 1, and then passes out from the first threading hole 331, and continues to extend along the cable drag chain. Finally, the cable is smoothly connected to the ARM arm flange seat 2 through another dust-proof wiring device 1. This wiring scheme not only ensures efficient cable management, but also greatly improves the dust-proof effect. In addition, with the lifting and lowering movement of the movable column 33 and the ARM arm flange seat 2, the cable 4 can adapt flexibly to maintain stable connection and transmission performance.

[0049] The column-type display panel handling robot is mainly used in the front process end of the flat panel display factory, for substrate interaction between CST and CV or process equipment, and is suitable for Glass before cutting and Panel after cutting.
