Description

Technical Field

[0001] The utility model relates to the field of display screen production, and more specifically, to a glass plate cleaning mechanism. Background Art

[0002] During the production of glass plates for the inner and outer screens of display screens, it is necessary to ensure dust-free operation in the production workshop to prevent dust from entering and affecting the production qualification rate of display screens. When the equipment is in operation for a long time and the glass plates are transported, the static electricity carried on their surface will absorb some fine dust, which needs to be cleaned in time to avoid defective products in the subsequent display screen production process.

[0003] Most existing glass plate cleaning mechanisms use dust blowing for cleaning, which not only has a poor cleaning effect, but may also cause the fan to suck in dust and drop it onto the glass plate. Another method is to use a rubber roller to roll over the surface of the glass plate to clean the dust. Although this method has a good cleaning effect, the rubber roller needs to be replaced frequently to avoid excessive dust on the rubber roller that reduces the cleaning effect and easily causes the dust to stick back to the glass plate.

[0004] Therefore, a novel glass plate cleaning mechanism is needed to solve the above problems. Utility Model Content

[0005] One purpose of the utility model is to solve the problem that the existing glass plate cleaning mechanism has poor cleaning effect or requires frequent maintenance, thus affecting production efficiency.

[0006] According to one aspect of the utility model, a glass plate cleaning mechanism is provided, comprising a mounting frame and a tape roller, wherein the mounting frame is fixed to the top of a conveyor belt, the tape roller is rotatably connected to the mounting frame, a tape roll is mounted on the tape roller, the tape on the tape roll is passed through a support roller and then wound onto a winding roller, and the support roller is used to press the adhesive surface of the tape against the glass plate.

[0007] Through this solution, the adhesive tape is used to stick away the dust on the surface of the glass plate. The adhesive tape can be driven as the glass plate is conveyed forward, so that the moving speed of the adhesive tape is consistent with the moving speed of the glass plate, ensuring that the glass plate can be cleaned with a new adhesive tape, avoiding the problem of repeated cleaning with used adhesive tape causing dust to stick back to the glass plate.

[0008] Preferably, the support roller is connected to a support cylinder, the support cylinder is fixed to a mounting frame, and the support cylinder is used to drive the support roller to move up and down.

[0009] Through this solution, when cleaning is not needed, the support cylinder drives the support roller to retract upward to avoid touching the conveyor belt and causing tape contamination. When cleaning is needed, the support roller is extended downward to the glass plate, thereby improving ease of use.

[0010] Preferably, the support cylinder is connected to the piston rod of the support cylinder through an elastic mechanism, the elastic mechanism includes a base, an extrusion spring and a slider, the slider is vertically slidably connected to the base, the extrusion spring always applies a downward thrust to the slider, and the support roller is rotationally connected to the slider.

[0011] Through this solution, the elastic mechanism can prevent the support cylinder from causing damage to the glass plate due to excessive force, and play a role in flexible cleaning.

[0012] Preferably, the stroke of the supporting cylinder is greater than the minimum distance between the supporting roller and the tape roller.

[0013] Through this solution, it is ensured that a new adhesive tape can be pulled out for cleaning after the support cylinder is extended, avoiding the used adhesive tape being pressed against the glass plate again to cause contamination of the glass plate, and further improving the reliability of the device.

[0014] Preferably, the rotating shaft of the winding roller is connected to the winding motor through a synchronous belt.

[0015] Through this solution, the winding motor only serves to wind up the tape, preventing the tape from sagging and contaminating the glass plate due to loose winding. The winding motor can also fix the used tape, preventing the used tape from being pulled out again and pressing against the glass plate during the extension of the support cylinder.

[0016] Preferably, the tape roller comprises a roller, an end cover and a limiting ring, the tape roll is sleeved on the roller, the limiting ring is arranged on both sides of the tape roll, and the limiting ring is fixed to the end of the roller by a pin.

[0017] Through this solution, the tape roll can be removed by removing the end cover after pulling out the pin, which avoids the problem of loosening caused by rotation of the tape roll compared to the traditional threaded connection.

[0018] One of the technical effects of the utility model is that the glass plate cleaning mechanism can realize effective cleaning of the glass plate while reducing the maintenance process, eliminating the need for frequent replacement of rubber rollers, and avoiding the problem of dust sticking back to the glass plate caused by repeated use of used tape, thereby greatly improving reliability.

[0025] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0026] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present invention, its application, or uses.

[0027] Techniques and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the techniques and equipment should be considered part of the specification.

[0028] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0029] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0030] like Figures 1 to 4 As shown, a glass plate 200 cleaning mechanism in an embodiment of the present application includes a mounting frame 100 and a tape roller 110. The mounting frame 100 is fixed to the top of the conveyor belt 300. The tape roller 110 is rotatably connected to the mounting frame 100. A tape roll 101 is installed on the tape roller 110. The tape 102 on the tape roll 101 is wound onto a winding roller 130 after passing through a supporting roller 120. The supporting roller 120 is used to press the adhesive surface of the tape 102 against the glass plate 200.

[0031] Through the scheme of this embodiment, the adhesive tape 102 is used to stick away the dust on the surface of the glass plate 200. The adhesive tape 102 can be driven as the glass plate 200 is conveyed forward, so that the moving speed of the adhesive tape 102 is consistent with the moving speed of the glass plate 200, ensuring that the glass plate 200 can be cleaned with a new adhesive tape 102, avoiding the problem of repeated cleaning with the used adhesive tape 102 causing the dust to stick back to the glass plate 200.

[0032] The bottom of the mounting frame 100 is fixed to the two side brackets of the conveyor belt 300, so that the tape roll 101 can be located directly above the glass plate 200. The width of the tape roll 101 is consistent with the width of the glass plate 200. Multiple tape rolls 101 can be arranged side by side to adapt to the width of the glass plate 200, or the tape roll 101 can be of customized width for easy replacement.

[0033] In one embodiment of the present application, the support roller 120 is connected to a support cylinder 121, which is fixed to the mounting frame 100. The support cylinder 121 is used to drive the support roller 120 to move up and down. When cleaning is not required, the support cylinder 121 drives the support roller 120 to retract upward to avoid contacting the conveyor belt 300 and causing contamination of the tape 102. When cleaning is required, the support roller 120 is extended downward to the glass plate 200, thereby improving the convenience of use.

[0034] In one embodiment of the present application, the support cylinder 121 is connected to the piston rod of the support cylinder 121 through an elastic mechanism 140, the elastic mechanism 140 includes a base 142, a squeeze spring 141 and a slider 143, the slider 143 is vertically slidably connected to the base 142, the squeeze spring 141 always applies a downward thrust to the slider 143, and the support roller 120 is rotatably connected to the slider 143. The elastic mechanism 140 can prevent the support cylinder 121 from causing damage to the glass plate 200 due to excessive force, and plays a role in flexible cleaning.

[0035] In one embodiment of the present application, the stroke of the support cylinder 121 is greater than the minimum distance between the support roller 120 and the tape roller 110. This ensures that after the support cylinder 121 is extended, a new tape 102 can be pulled out for cleaning, thereby preventing the used tape 102 from being applied to the glass plate 200 again to contaminate the glass plate 200, and further improving the reliability of the device.

[0036] In one embodiment of the present application, the rotating shaft of the winding roller 130 is connected to the winding motor 131 through a synchronous belt. The winding motor 131 only serves to wind up the adhesive tape 102 to prevent the adhesive tape 102 from sagging and contaminating the glass plate 200 due to loose winding. The winding motor 131 can also serve to fix the used adhesive tape 102 to prevent the used adhesive tape 102 from being pulled out again and pressed against the glass plate 200 during the extension of the support cylinder 121.

[0037] The winding motor 131 is a stepper motor or a servo motor, which can adjust its own speed according to the conveying speed of the conveyor belt 300, so that the recovery speed of the tape 102 is consistent with the moving speed of the glass plate 200, avoiding the problem that the tape 102 is not recovered in time and falls onto the glass plate 200.

[0038] In one embodiment of the present application, the tape roller 110 includes a roller 111, an end cap 112, and a limiting ring 114. The tape roll 101 is sleeved on the roller 111, and the limiting ring 114 is arranged on both sides of the tape roll 101. The limiting ring 114 is fixed to the end of the roller 111 through a pin 113. After the pin 113 is pulled out and the end cap 112 is removed, the tape roll 101 can be removed. Compared with the traditional threaded connection, the problem of loosening caused by the rotation of the tape roll 101 is avoided.

[0039] One technical effect of the utility model is that the glass plate cleaning mechanism can realize effective cleaning of the glass plate while reducing the maintenance process, without the need to frequently replace the rubber roller, and can avoid the problem of dust sticking back to the glass plate caused by the reuse of the used tape, thereby greatly improving reliability. Although some specific embodiments of the utility model have been described in detail through examples, it should be understood by those skilled in the art that the above examples are only for illustration and not for limiting the scope of the utility model. It should be understood by those skilled in the art that the above embodiments can be modified without departing from the scope and spirit of the utility model.
