Description

Technical Field

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

[0002] In the display manufacturing industry, product yield directly determines a company's production efficiency and market competitiveness, and particles are one of the core indicators affecting yield during display production. The production process of displays is precise and complex, from substrate processing and thin-film deposition to photolithography and encapsulation. It demands extremely high cleanliness in the production environment and during equipment operation. Even tiny particles adhering to the display substrate or the surface of key components can cause defects such as dead pixels, bright lines, and uneven color in the display panel, and in severe cases, even lead to the scrapping of an entire batch of products. Therefore, strict particle control has become an industry consensus and a core production requirement in the display manufacturing field.

[0003] In some key processes of display screen production, precise operation relies on specific production equipment. The optical axis, as a crucial transmission component, plays a vital role in driving the movement of parts in specific processes. To meet the positional adjustment requirements of components during the process, the optical axis needs to continuously move back and forth axially. During this movement, the optical axis inevitably comes into contact with and rubs against other adjacent components in the equipment. Due to the material properties of the components and the physical effects of the friction process, this contact friction generates a large number of particles. These particles are directly scattered inside the production equipment and in the process operation area. If not cleaned promptly and effectively, they can easily spread and adhere to critical parts of the display screen production process, thus posing a serious threat to product quality and yield.

[0004] To address the particles generated by friction along the optical axis, the industry has attempted to clean them using conventional suction fans. However, in practical applications, this method has proven to be extremely inefficient. The core reason is that during axial movement and friction, the surface of the optical axis generates electrostatic effects. Simultaneously, the particles generated by friction between the optical axis and components are small in size and possess strong adsorption properties, causing most particles to adhere tightly to the optical axis surface and become difficult to remove. Suction fans can only effectively clean a small amount of particles suspended in the air or lightly attached; they are almost ineffective at removing particles firmly adhering to the optical axis surface. Currently, the industry has not found a more efficient and suitable particle cleaning technology for this scenario. The challenge of cleaning particles generated by optical axis friction has become a significant bottleneck restricting the improvement of cleanliness in display manufacturing equipment and the stability of product yield, urgently requiring a breakthrough.

[0028] The components include: housing 1, through hole 1a, pipe connector 1b, notch 1c, vertical plate 2, horizontal section 2a, vertical section 2b, first vertical hole 2b1, brush 3, handle 3a, second vertical hole 3a1, and brush bristles 3b. Detailed Implementation

[0029] like Figure 1-7 As shown, this embodiment includes a housing 1, a suction fan, a vertical plate 2, and a brush 3.

[0030] The shell 1 is a box structure with the opening facing upward. In this embodiment, the shell 1 adopts a cubic structure. In other embodiments, the shell 1 may also adopt a triangular prism or a cylinder shape.

[0031] The bottom of the housing 1 is provided with a through hole 1a, specifically, the through hole 1a is located at the very center of the bottom.

[0032] The suction fan is connected to the through hole 1a through a pipe. Furthermore, in this embodiment, a pipe connector 1b is provided on the bottom outer side of the housing 1, which is connected to the through hole 1a. The pipe connector 1b is connected to the suction fan through a pipe, and the pipe connector 1b and the pipe are detachably connected. Specifically, the pipe connector 1b and the pipe can be fastened together by using a clamp.

[0033] The upright plate 2 is erected at the bottom of the shell 1, specifically on the side of the through hole 1a. The upright plate 2 should not block the through hole 1a, nor should it be too far away from the through hole 1a.

[0034] In this embodiment, the upright plate 2 adopts an L-shaped plate structure, which includes a rectangular horizontal section 2a and a rectangular vertical section 2b perpendicular to the horizontal section 2a.

[0035] The horizontal section 2a of the upright plate 2 is fixed to the bottom of the housing 1 by at least two bolts, which prevent the upright plate 2 from rotating. The vertical section 2b of the upright plate 2 is provided with a first vertical hole 2b1, which is specifically a vertically arranged oval hole.

[0036] In this embodiment, the brush 3 includes a handle 3a and bristles 3b. The handle 3a is a sheet-like structure, specifically a rectangular sheet with the same shape and size as the vertical section 2b of the upright plate 2. The handle 3a is provided with a second vertical hole 3a1, the position of which corresponds to the first vertical hole 2b1. After the bolt passes through the first vertical hole 2b1 and the second vertical hole 3a1, the brush 3 is fixed to the upright plate 2 by tightening with a nut.

[0037] The bristles 3b are located at the upper end of the handle 3a.

[0038] In this embodiment, the first vertical hole 2b1 and the second vertical hole 3a1 have the same shape and size, and their positions correspond. In the initial installation state, the handle 3a coincides exactly with the vertical section 2b of the upright plate 2, and at this time, the first vertical hole 2b1 and the second vertical hole 3a1 also coincide exactly. The space inside the housing 1 is relatively narrow. The advantage of this structure is that during installation, as long as the vertical section 2b of the upright plate 2 coincides with the handle 3a of the brush 3, the position can be known to be in place. At the same time, when adjusting the brush 3 upwards, the maximum adjustment distance is the distance of one vertical hole.

[0039] To ensure that the brush 3 is only adjustable up and down, this embodiment has two first vertical holes 2b1 and two corresponding second vertical holes 3a1 arranged side by side. This embodiment can provide space for adjusting the height of the brush 3 by tightening and loosening the bolts in the narrow space of the housing 1 through the vertical misalignment of the bolts in the two first vertical holes 2b1.

[0040] In another embodiment, the first vertical hole 2b1 or the second vertical hole 3a1 is a round hole. In this case, the brush 3 can be adjusted upwards by the distance of one vertical hole. However, the bolt positions of the fixed plate 2 and the handle 3a cannot be moved. The adjustment of the height of the brush 3 by tightening and loosening the bolts in the narrow space inside the housing 1 is not as flexible as in this embodiment.

[0041] Preferably, in this embodiment, notches 1c for accommodating the optical axis are provided on two opposite sidewalls of the housing 1. Specifically, the two notches 1c are semicircular in position and shape. By having the notches 1c cover the optical axis, it can be ensured that all particles on the optical axis fall into the housing 1.

[0042] Furthermore, two upright plates 2 and two brushes 3 are each set and located on both sides of the through hole 1a, with the brush surfaces of the two brushes 3 corresponding to the two notches 1c respectively. When the optical axis moves back and forth, the upward-set brushes 3 act on the optical axis. From the perspective of relative motion, if the optical axis is set to a stationary state, then the brushes 3 are brushing back and forth on the optical axis.

[0043] It should be noted that the descriptions of directions such as up, down, left, right, front, back, top, bottom, tail, horizontal, and vertical in this application are all based on the accompanying drawings and are only used to more clearly express the technical solution, and do not indicate any limitation on the scope of protection.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
