Description

Technical Field

[0001] This utility model belongs to the field of display manufacturing, and specifically relates to a friction particle collection device. Background Technology

[0002] In the core processes of display manufacturing, the coating machine plays an indispensable and crucial role, and its operational stability directly affects the smoothness of the production process and the final quality. To achieve precise transfer of the substrate during the process, the coating machine is equipped with a pulley assembly that specifically supports the bottom guide rod of the substrate carrier. Multiple sets of pulleys are arranged in an orderly array, and the guide rod can slide smoothly above the pulley assembly along a preset straight direction, thereby completing the transfer of the substrate at different process stages.

[0003] However, since the guide rod is made of metal, friction inevitably occurs between its contact surface and the pulley during their continuous relative movement. This friction causes minor wear on the metal surface, resulting in tiny particles. Although these particles are small, they can significantly impact display production: they may float in the process environment inside the machine, and once they adhere to the substrate surface or enter the coating chamber, they can easily cause coating defects, abnormal display areas, and ultimately directly reduce the yield rate of display products, leading to efficiency losses and cost pressures for manufacturers.

[0004] Currently, there is no effective solution in the industry for the problem of particles generated by friction between the metal guide rod and the pulley. Utility Model Content

[0028] The components include: pulley 1, mounting shaft 2, bracket box 3, mounting plate 3a, through hole 3b, first magnet 4, protective cover 5, support box 6, second magnet 7, and cover plate 8. Detailed Implementation

[0029] like Figure 1-5 As shown, this embodiment includes a bracket box 3, a first magnet 4, a protective cover 5, a support box 6, a second magnet 7, and a cover plate 8.

[0030] This embodiment is applied to the scenario where the guide rod slides on the pulley 1. Therefore, the bracket box 3 is placed directly below the pulley 1. In this scenario, the pulley 1 is fixed on the mounting shaft 2, and the pulley 1 and the mounting shaft 2 are coaxial.

[0031] The opening of the bracket box 3 faces upward and is directly opposite the pulley 1.

[0032] In this embodiment, one side plate of the bracket box 3 is set as a mounting plate 3a. The mounting plate 3a has a through hole 3b corresponding to the mounting shaft 2. The mounting plate 3a has a certain thickness, which is greater than the diameter of the mounting bolt. The through hole 3b passes through the pulley 1 and is sleeved on the mounting shaft 2. The mounting bolt passes through the thickness surface of the mounting plate 3a and abuts against the mounting shaft 2 to fix the bracket box 3 on the mounting shaft 2.

[0033] In this embodiment, the side plate on the bracket box 3 opposite to the mounting plate 3a is higher than the guide rod to prevent the tiny particles generated by the friction between the guide rod and the pulley 1 from flying out of the bracket box 3.

[0034] The first magnet 4 is located inside the bracket box 3, directly below the pulley 1. The first magnet 4 is long and its length direction is consistent with the length direction of the guide rod.

[0035] The protective cover 5 is placed over and fits against the first magnet 4. In this embodiment, bolts are used to pass through the bottom of the protective cover 5, the first magnet 4 and the bracket box 3 in sequence and then connected with nuts to fix the protective cover 5 and the first magnet 4 inside the bracket box 3.

[0036] The protective cover 5 is designed to fit the first magnet 4. This not only makes it easier to fix the two firmly, but also ensures that the magnetic force of the first magnet can penetrate the protective cover 5. The protective cover 5 is preferably made of a thin plastic material.

[0037] The support box 6 is located on the side of the pulley 1. The support box 6 can be located on one side of the pulley 1 with the guide rod moving forward as the front, and this side is the front of the pulley 1; or the support box 6 can be located on the front and back sides of the pulley 1 respectively.

[0038] In this embodiment, the support box 6 is fixed on the bracket box 3. Specifically, the bolt passes through the bottom plate of the bracket box 3 and is threaded to the thickness surface of the mounting plate 3a, thereby fixing the support box 6 on the bracket box 3.

[0039] The opening of the support box 6 faces upward, and a second magnet 7 is provided inside the support box 6. Specifically, the second magnet 7 is strip-shaped, and its length direction is consistent with the length direction of the guide rod. The second magnet 7 is located directly below the guide rod.

[0040] It also includes a cover plate 8, which covers the second magnet 7 and is fixed by bolts. Specifically, the bolts are threaded through the cover plate 8 and the second magnet 7 and then connected to the bottom plate of the support box 6, thereby fixing the cover plate 8 and the second magnet 7 to the support box 6.

[0041] Preferably, the thickness of the second magnet 7 is equal to the height of the nut of the bolt used to fix the support box 6 to the bracket box 3, so that the second magnet 7 and the nut of the bolt can serve to support the cover plate 8.

[0042] Furthermore, the bolts and the second magnet are located on two opposite sides of the support box 6, which allows the cover plate 8 to be subjected to more even force.

[0043] Similarly, the cover plate 8 is also made of thin plastic material to ensure that the magnetic force of the second magnet 7 can penetrate the top surface.

[0044] Preferably, the height of the installed cover plate 8 is less than the height of the support box 6, so that the cover plate 8 and the side plate of the support box 6 form a groove structure, which can collect the fine particles generated by the friction between the guide rod and the pulley 1.
