Description

Technical Field

[0001] This utility model belongs to the field of display glass production technology, and specifically relates to a glass substrate pre-wetting and cleaning device. Background Technology

[0002] As a core material in display panel manufacturing, the surface cleanliness of glass substrates directly affects the yield of subsequent processes. In the pre-wet cleaning stage, physical rinsing is necessary to remove particles and organic contaminants from the substrate surface, while avoiding water residue that could cause secondary contamination. In existing technologies, traditional cleaning devices often employ a fixed nozzle layout, with the spray angle and substrate spacing not adjustable. When handling irregularly shaped substrates or workpieces with unevenly distributed contaminants, this can easily lead to rinsing dead zones and incomplete cleaning. While some adjustable devices have position adjustment functions, the adjustment mechanism is slow to respond, making it difficult to match the high-speed operation requirements of production lines. Furthermore, the lack of residual liquid treatment structures results in uneven water film thickness on the substrate surface, increasing the load on subsequent drying processes. Utility Model Content

[0003] To address the issue of insufficient cleaning efficiency for glass substrates in existing technologies, a pre-wetting cleaning device for glass substrates is proposed. This invention provides the following technical solution:

[0004] A glass substrate pre-wetting cleaning device includes a crossbeam erected on a conveyor line. Two cleaning components are symmetrically arranged on the crossbeam. Each cleaning component includes a lifting drive device, a mounting plate, a rotating drive device, a water supply pipe, and a nozzle for rinsing the glass substrate. The lifting drive device is mounted and connected to the crossbeam and driven by the mounting plate. The rotating drive device is mounted and connected to the mounting plate and driven by the water supply pipe. The nozzle is connected in communication with the water supply pipe.

[0005] Preferably, the crossbar is provided with sliding grooves on both sides, and a slide rail installed on the conveyor line is slidably connected to the sliding grooves.

[0006] Preferably, a walking drive device is installed on both sides of the cross frame, a toothed plate is fixedly connected to one side of the slide rail, and a walking gear meshing with the toothed plate is connected to the output end of the walking drive device.

[0007] Preferably, a guide rod is fixedly connected to the mounting plate, and a guide hole is provided on the crossbar, with the guide rod slidably connected vertically to the guide hole.

[0008] Preferably, a scraper is fixedly connected to the underside of the mounting plate.

[0009] Preferably, the scraper is located on the lower rear side of the mounting plate, and the water supply pipe is located on the lower front side of the mounting plate.

[0010] Preferably, the scraper is connected to the mounting plate via a fixing plate. The fixing plate is C-shaped and has a positioning groove with an opening facing forward in the middle for inserting the mounting plate.

[0011] Preferably, the fixing plate is connected to the mounting plate and the scraper by bolts.

[0012] Preferably, the scraper includes an insert plate and a scraper strip. The insert plate is provided with a slot that opens downward and extends through the left and right sides. The cross-section of the slot and the cross-section of the upper end of the scraper strip are both inverted U-shapes. The scraper strip is inserted into the slot.

[0013] Preferably, multiple nozzles are arranged at equal intervals.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The vertical displacement adjustment function enables precise control of the distance between the nozzle and the glass substrate surface, which can effectively avoid the risk of mechanical collision and maintain a stable rinsing pressure for a long time, ensuring both safety and work efficiency in the cleaning process, especially suitable for high-precision glass substrate processing scenarios.

[0016] 2. The rotary drive device gives the water pipe multi-angle adjustment capability, so that the spray direction of the nozzle can be dynamically adapted to match the curvature of the substrate surface and the distribution characteristics of pollutants. Combined with the fan-shaped rinsing surface formed by the tilted nozzle, the cleaning coverage is significantly expanded and the edge dead corners of traditional solutions are eliminated, and the cleaning efficiency is significantly improved under complex working conditions.

[0017] 3. The scraper adopts an inverted U-shaped slot and a plug-in structure for the scraper blade. The double anti-detachment design ensures the stability of high-speed scraping operations. In addition, the guide groove on the inner wall of the slot discharges the seeping liquid in real time, effectively avoiding the risk of rust and jamming at the connection point, significantly extending the service life of the scraper blade and simplifying the maintenance process.

Detailed Implementation

[0022] The directional terms mentioned in the following embodiments, such as "up", "down", "left", and "right", are only for reference to the accompanying drawings. Therefore, the directional terms used are for illustration and not for limiting the invention of this utility model.

[0023] like Figure 1-3 As shown, a glass substrate pre-wetting cleaning device includes a crossbeam 1 mounted on a conveyor line. Two cleaning components 2 are symmetrically arranged on the crossbeam 1. Each cleaning component 2 includes a lifting drive 21, a mounting plate 22, a rotary drive 23, a water supply pipe 24, and a nozzle 25 for rinsing the glass substrate. The lifting drive 21 is mounted to the crossbeam 1, and its output end is hinged to the mounting plate 22. The rotary drive 23 is mounted to the mounting plate 22 and driven by the water supply pipe 24. The nozzle 25 is connected to the water supply pipe 24 and operates vertically. The displacement adjustment function enables precise control of the distance between the nozzle 25 and the glass substrate surface, which can avoid the risk of collision and maintain a moderate rinsing pressure. The rotary drive device 23 gives the water pipe 24 the ability to adjust the angle, so that the nozzle 25 can dynamically adjust the spray direction according to the curvature of the substrate surface or the distribution characteristics of pollutants, which significantly improves the cleaning coverage under complex working conditions. In addition, the tilted nozzle 25 can achieve the effect of rinsing to both sides. Combined with the rotary drive, a fan-shaped rinsing surface is formed, which effectively eliminates cleaning dead corners, achieves efficient pre-cleaning treatment, and improves cleaning efficiency.

[0024] Furthermore, slide grooves 11 are provided on both sides of the cross frame 1, and slide rails 3 installed on the conveyor line are slidably connected to the slide grooves 11, so that the cross frame 1 can adapt to glass substrates of different lengths and specifications, and match the cleaning cycle with the speed of the conveyor line to achieve seamless connection of the production process.

[0025] Furthermore, a walking drive device 4 is installed on both sides of the cross frame 1, and a toothed plate 6 is fixedly connected to one side of the slide rail 3. The output end of the walking drive device 4 is connected to a walking gear 5 that meshes with the toothed plate 6. With the help of encoder feedback, position closed-loop control is realized, so as to realize high-precision automatic movement of the cross frame 1.

[0026] Furthermore, a guide rod 26 is fixedly connected to the mounting plate 22, and a guide hole is provided on the crossbeam 1. The guide rod 26 is vertically slidably connected to the guide hole, which can prevent the mounting plate 22 from tilting or deflecting.

[0027] Furthermore, a scraper 27 is fixedly connected to the lower part of the mounting plate 22. The scraper 27 is located on the lower rear side of the mounting plate 22, and the water supply pipe 24 is located on the lower front side of the mounting plate 22. Specifically, the scraper 27 includes an insert plate 271 and a scraper 272. The insert plate 271 is provided with a slot that opens downward and extends through the left and right sides. The cross-section of the slot and the cross-section of the upper end of the scraper 272 are both inverted U-shapes. The scraper 272 is inserted into the slot, providing double protection against falling off, facilitating quick replacement of the scraper 272, and preventing the scraper 272 from accidentally falling off during high-speed scraping operations. A guide groove is provided on the inner wall of the slot to drain the seeping liquid in time and prevent corrosion and jamming at the connection parts.

[0028] The scraper 27 is connected to the mounting plate 22 via a fixing plate 28. The fixing plate 28 is C-shaped and has a positioning groove 281 with its opening facing forward in the middle. The upper side wall of the positioning groove 281 abuts against the upper side of the mounting plate 22, and there is a gap between the lower side wall of the positioning groove 281 and the mounting plate 22 for bolting the scraper 27. At the same time, the fixing plate 28 is also connected to the mounting plate 22 via bolts.

[0029] Furthermore, multiple nozzles 25 are evenly spaced to ensure that the distribution of water flow impact force remains highly uniform and to avoid micro-deformation of the substrate caused by local over-rushing.

[0030] Specifically, the lifting drive device 21 uses a cylinder, while the rotary drive device 23 and the walking drive device 4 use servo motors or stepper motors.
