Description

Technical Field

[0001] The invention relates to the technical field of plate cleaning equipment, and in particular to a plate scrubbing equipment. Background Art

[0002] Currently, after the production of some boards is completed, the surface of the boards needs to be brushed and cleaned. Boards include display panels, glass substrates, and carrier glass. Taking the display panel as an example, in the display panel cleaning process, the surface of the display panel needs to be brushed with a brushing equipment.

[0003] The existing scrubbing equipment includes a mounting frame and a disc brush. Two mounting frames are arranged relatively to each other and can move closer to or farther from each other. Multiple disc brushes are rotatably mounted on the side where the two mounting frames are close to each other. The bristles of the disc brushes are generally made of soft materials such as nylon or polyvinyl alcohol. When the scrubbing equipment is working, the mounting frame drives the disc brush to press against the display panel, causing the bristles of the disc brush to deform to a certain extent. With the rotation of the disc brush itself, the stains and impurities on the surface of the display panel are removed by physical friction.

[0004] Due to the influence of the deformation of the mounting frame, the installation error of the mounting frame and the installation error of the disc brush, after the disc brush is installed on the mounting frame, the multiple disc brushes in the group of disc brushes close to the display panel are not in the same horizontal plane, which will cause the multiple disc brushes to press against the display panel and produce different deformations. If the deformation is too large, the display panel will be scratched or even damaged. If the deformation is too small, the cleaning effect will be affected. Therefore, each time the disc brush is installed, a lot of time is required to adjust the levelness, which greatly affects the production progress and efficiency. Summary of the invention

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0035] Refer to the following Figures 1 to 3 The plate scrubbing equipment provided by the present invention is described.

[0036] The plate scrubbing device comprises a mounting frame 1 and a disc brush, wherein a plurality of mounting frames 1 are arranged in parallel along a first direction, and two mounting frames 1 in each pair of mounting frames 1 are arranged along a second direction, the second direction is perpendicular to the first direction, and the two mounting frames 1 in each pair of mounting frames 1 are arranged opposite to each other and can approach and move away from each other. In each pair of mounting frames 1, a plurality of disc brushes are rotatably installed on the side where the two mounting frames 1 are close to each other.

[0037] Specifically, in this embodiment, the plate to be scrubbed takes the display panel 100 as an example. The display panel 100 is placed horizontally and conveyed along the first direction. It can be conveyed manually or automatically by a conveying device. The specific conveying method is not limited. In this embodiment, the multiple disc brushes on each mounting frame 1 are arranged along the third direction, and the third direction is perpendicular to the second direction and the first direction. In this embodiment, the first direction and the third direction are both horizontal directions, and the second direction is a vertical direction. In other embodiments, the first direction can also be tilted to a certain extent, that is, adaptive adjustment is performed as needed.

[0038] The plate scrubbing device also includes a base 6, and a pair of bases 6 are provided for each pair of mounting frames 1, and each pair of bases 6 are distributed along the third direction, and a pair of mounting frames 1 are provided between the pair of bases 6; and each base 6 is slidably connected to a sliding seat 61 along the second direction, and both ends of each mounting frame 1 are slidably connected to the sliding seat 61, and the mounting frame 1 slides along the third direction, and each of the above-mentioned sliding parts can be driven by a driving member such as a cylinder, an oil cylinder or a servo motor. In this embodiment, a cylinder is used as an example, and each sliding part is guided by a linear track. The specific structure is the prior art and will not be repeated here. In some other embodiments, an integral frame or substrate can also be driven to replace the above-mentioned base 6, and the specific form is not limited.

[0039] Based on the above, when the display panel 100 needs to be cleaned, the display panel 100 is placed between a pair of mounting frames 1. When the display panel 100 is conveyed forward, the pair of mounting frames 1 drive a plurality of disc brushes to abut against the upper and lower surfaces of the display panel 100, and all the disc brushes rotate simultaneously, thereby scrubbing the surface of the display panel 100. During the cleaning process, a cleaning agent may be sprayed onto the surface of the display panel 100 through a spray device to enhance the scrubbing effect of the display panel 100.

[0040] In addition, since there is a certain gap between two adjacent disc brushes on the same mounting frame 1, an invalid cleaning area, i.e., a cleaning blind area, will appear on the surface of the display panel 100; therefore, in this embodiment, on two adjacent mounting frames 1 distributed along the first direction, the multiple disc brushes on the two mounting frames 1 are staggered, so that the cleaning blind area is covered by the cooperation of the multiple mounting frames 1, and the mounting frames 1 can slide along the third direction, which further reduces the cleaning blind area and improves the cleaning effect of the display panel 100.

[0041] Furthermore, each disc brush includes a mounting seat 2, a mounting shaft 3 and a disc brush body 4. The mounting seat 2 is connected to the mounting frame 1, and the mounting shaft 3 is rotatably connected to the mounting seat 2. The axial direction of the mounting shaft 3 is perpendicular to the surface of the plate, and the mounting shaft 3 can be extended and retracted along its own axial direction. The disc brush body 4 is connected to the side of the mounting shaft 3 away from the mounting frame 1, and the bristles of the disc brush body 4 can be deformed when they abut the plate.

[0042] Specifically, the mounting seat 2 is in a circular cylindrical shape, and the mounting seat 2 is vertically arranged. The mounting seat 2 is provided with a mounting groove 21 at one end close to the mounting frame 1, and the interior of the mounting groove 21 is provided with a bearing 22. The mounting shaft 3 includes a shaft core 31 and a shaft sleeve 32, and the shaft sleeve 32 is slidably sleeved on the outside of the shaft core 31. One of the shaft core 31 and the shaft sleeve 32 is rotatably connected to the mounting seat 2, and the other is connected to the disc brush body 4. Specifically in this embodiment, the end of the shaft core 31 away from the shaft sleeve 32 extends out of the mounting seat 2, and the inner ring of the bearing 22 is penetrated. The end of the shaft sleeve 32 away from the shaft core 31 extends out of the mounting seat 2 in a direction away from the mounting frame 1, and is connected with a connecting plate 322. The disc brush body 4 is detachably connected to the connecting plate 322 by bolts. The bristles on the disc brush body 4 are made of plastic material, and polyvinyl alcohol is used as an example in this embodiment. In some other embodiments, the shaft sleeve 32 can also be rotatably connected to the mounting seat 2, and the shaft core 31 is connected to the disc brush body 4.

[0043] Furthermore, each mounting frame 1 is rotatably provided with a driving shaft 11, which is driven by a motor, and the axial direction of the driving shaft 11 is perpendicular to the axial direction of the mounting shaft 3. The driving shaft 11 can drive all the mounting shafts 3 on the mounting frame 1 where it is located to rotate, and a bevel gear transmission, a chain transmission or a belt transmission is adopted between the driving shaft 11 and the mounting shaft 3. In this embodiment, a pair of bevel gears are used between the driving shaft 11 and each shaft core 31, so as to realize the rotation of the mounting shaft 3 and drive the disc brush body 4 to rotate synchronously. In addition, the bevel gear has the advantages of noise reduction, shock absorption, light weight, low cost, long life, high load bearing capacity, easy molding and good lubricity.

[0044] Furthermore, the shaft sleeve 32 is provided with a flow port 321, which is located outside the mounting seat 2. The flow port 321 can be used to fill or extract a medium into or from the shaft sleeve 32, and a valve is connected to the flow port 321. The medium in this embodiment is compressed air, and the flow port 321 is connected to a vacuum air source, such as an air pump or an air tank, through a hose. A manual ball valve, a manual pressure regulating valve, and an electric proportional valve are sequentially arranged in the middle of the hose along the direction from the vacuum air source to the flow port 321. In other embodiments, an air inlet valve and an exhaust valve can also be installed in the middle of the hose.

[0045] Based on the above, before the disc brush works, the manual ball valve is opened to realize the on-off of the gas circuit, and then the pressure inside the regulating hose of the manual ball valve is adjusted, and then the pressure inside the sleeve 32 is precisely adjusted through the electrical proportional valve, so that the sleeve 32 can slide along its axial direction relative to the shaft core 31, so that the distance between each disc brush body 4 and the mounting frame 1 can be individually and precisely adjusted, so as to facilitate the adjustment of multiple disc brush bodies 4 on the same mounting frame 1 to the same plane. When brushing the display panel 100, all the disc brush bodies 4 are driven to abut against the display panel 100 through the mounting frame 1, so that the deformation of multiple disc brush bodies 4 abutting against the display panel 100 can be the same, and then the surface of the display panel 100 is rotated and brushed by the disc brush body 4 to remove the stains and debris on the surface of the display panel 100, which not only ensures the cleaning effect of the plate, but also prevents the display panel 100 from being damaged, greatly speeding up the production progress and improving the production efficiency. It should be noted that, due to the connection of the hose to the shaft sleeve 32 , the shaft sleeve 32 performs reciprocating rotation during operation, rather than unidirectional full circle rotation, in order to protect the hose.

[0046] In addition, when the disc brush body 4 made of polyvinyl alcohol is used with detergent, the external dimensions of the disc brush body 4 will change to a certain extent after a period of time due to the influence of temperature and detergent; since there are a large number of disc brush bodies 4, different disc brush bodies 4 are affected to different degrees, resulting in changes in the horizontal plane of the disc brush body 4. Through the individually adjustable disc brush body 4, the disc brush bodies 4 with different deformation amounts can be adjusted to the same height, thereby further accelerating the production progress and improving production efficiency.

[0047] It is worth noting that the outer sleeve of the shaft sleeve 32 is provided with a sealing ring 5, and the shaft sleeve 32 is rotatably matched with the inner ring of the sealing ring 5, and the sealing ring 5 is connected to the mounting seat 2. The sealing ring 5 seals the gap between the mounting seat 2 and the shaft sleeve 32, so that external dust, liquids, cleaning agents and other substances are not easy to enter the interior of the mounting seat 2 and cause pollution to the shaft core 31, thereby making the sliding of the shaft sleeve 32 more stable. The inner ring of the sealing ring 5 is provided with an annular groove 51 along its circumference, and the annular groove 51 is provided with two grooves along the axial direction of the sealing ring 5. The annular groove 51 can improve the rigidity and strength of the sealing ring 5, making the sealing ring 5 more durable and stable, and at the same time increase the heat dissipation area of ​​the sealing ring 5, which is convenient for the sealing ring 5 to dissipate heat.

[0048] Furthermore, the plate scrubbing device further comprises a pressure detection mechanism, which is configured to detect the pressure exerted by the disc brush body 4 on the surface of the plate when scrubbing the plate. Specifically in this embodiment, the pressure detection mechanism comprises a film pressure sensor and a controller, and the film pressure sensor and the electrical proportional valve are both electrically connected to the controller.

[0049] Specifically, when detecting the pressure of the disc brush body 4 on the surface of the display panel 100, a thin film pressure sensor is attached to the surface of the display panel 100, and then the display panel 100 passes between two groups of disc brush bodies 4. The pressure states at different positions are fed back by the thin film pressure sensor, and the electrical signal is transmitted to the controller. The controller then controls the opening of the electrical proportional valve to automatically adjust the position of each disc brush body 4, so that the pressure of each disc brush body 4 on the surface of the display panel 100 reaches a preset value, so as to ensure the cleaning effect while protecting the display panel 100.

[0050] In addition, after the position adjustment of the disc brush body 4 is completed, the product with the thin film pressure sensor can be reversed to detect the pressure of each disc brush body 4 acting on the surface of the display panel 100 again, so that the overall pressure uniformity is greater than 95% (95% is a recommended value, and the parameter can be adjusted according to actual conditions, uniformity = 1-(maximum pressure-minimum pressure) / (maximum pressure+minimum pressure)), and this reciprocating cycle is a cycle. If the uniformity cannot be adjusted to the preset value after three cycles, the equipment will issue an alarm to prompt the staff whether the group of disc brush bodies 4 needs to be replaced. After the adjustment of the first group of disc brush bodies 4 is completed, the pressure value corresponding to the pressing amount of the first group of disc brush bodies 4 is set as the target value, and the subsequent disc brush bodies 4 are adjusted based on this. The pressure value deviation of the disc brush bodies 4 on the surface of the display panel 100 on the multiple pairs of mounting frames 1 is ±5%, thereby taking into account both the cleaning effect and the protection of the display panel 100.

[0051] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
