Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal panel manufacturing, in particular to a guide mechanism for a glass washing machine. Background Art

[0002] When glass cleaning machines in LCD panel manufacturing plants use conveyor wheels to transport glass, guide wheels are installed on both sides of the conveyor wheel to prevent the glass from shifting during transportation. This helps to regulate the glass transportation route.

[0003] However, during long-term use, the glass on the transmission wheel contacts the guide wheel, which can easily cause the side wall of the guide wheel to be worn by the edge of the glass. When the guide wheel is worn to a certain depth, it is very easy to cause glass fragments.

[0004] In order to solve the problem of guide wheel wear, the guide wheel needs to be replaced frequently, but frequent replacement of guide wheels will increase material costs. Therefore, it is urgent to design an adjustable guide wheel to solve the problem of frequent replacement and extend the service life of a single guide wheel. Utility Model Content

[0005] The purpose of the present utility model is to provide a guide mechanism of a glass washing machine in which the guide wheel can be reused multiple times, thereby solving the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions:

[0007] A guide mechanism for a glass washing machine, which is used to guide the transportation direction of a glass sheet and limit the glass sheet from both sides, and comprises: a fixed bracket; a column fixed to the fixed bracket along the height direction of the fixed bracket; a guide wheel rotatably mounted on the outer circumference of the column, and the outer circumferential surface of the guide wheel is in contact with the glass sheet; a sliding pad which is movably mounted on the column and is respectively arranged on the upper and lower sides of the guide wheel; and a locking ring screwed on one end of the column extending from the upper side of the fixed bracket, for fixing the upper end of the column to the fixed bracket.

[0008] Compared with the prior art, the bearing and the pick-and-place arm having the bearing involved in the present invention have at least the following beneficial effects:

[0009] The present invention adjusts the height of the guide wheel by stacking sliding pads. The position of the base (lower cover) remains unchanged, and the stress point of the guide wheel is changed to achieve the function that could be achieved by replacing the guide wheel in the past. That is, the concept of adjustability is introduced for the disposable consumables (guide wheels) in the past, which greatly extends the service life of the consumables, thereby achieving the purpose of reducing costs. In addition, in the technical solution of the present invention, the column can be fixed by designing a U-shaped fixing bracket. The two-point fixing bracket can effectively reduce the impact of excessive stress from the glass sheet on the column, prevent the column from tilting, and make the guide wheel rotate more stably. In addition, a through hole is provided on the upper cover of the U-shaped fixing bracket, and the upper cover can be flipped upward, which greatly facilitates the disassembly and assembly of the column and saves the time of replacing the guide wheel.

DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work are within the scope of protection of this application.

[0016] like Figure 1 As shown, the guide mechanism 100 of the glass cleaning machine provided by the present invention is used in conjunction with a conveying device for glass sheets to guide the transport direction of the glass sheets and limit the glass sheets from both sides. Typically, a plurality of guide mechanisms 100 of the glass cleaning machine are provided along two opposing sides of the conveying device. That is, the guide mechanism 100 of the glass cleaning machine is provided along the conveying direction of the glass sheets. The guide mechanism 100 of the glass cleaning machine includes a fixed bracket 10, a column 20, a guide wheel 30, a plurality of sliding pads 40, and a locking ring 50. The fixed bracket 10 is fixedly mounted on the conveying device; the column 20 is mounted on the fixed bracket 10; the plurality of sliding pads 40 and the guide wheel 30 are mounted on the column 20; and the locking ring 50 is connected to the top of the column 20 to position the guide wheel 30 at different positions relative to the column 20.

[0017] The fixed bracket 10 is a hollow, semi-enclosed frame that, when viewed from the left and right sides, forms a "U" shape with its opening facing the right. The fixed bracket 10 includes an upper cover 101, a lower cover 103 opposite the upper cover 101, and a back plate 105 perpendicularly connected to the upper and lower covers 101 and 103 at the upper and lower ends, respectively. The lower cover 103 is fixedly mounted on the conveying device, the back plate 105 is fixedly mounted on the end of the lower cover 103 away from the conveying device, and one end of the upper cover 101 is fixedly mounted on the end of the back plate 105 away from the lower cover 103. The upper and lower covers 101 and 103 are arranged parallel to each other at intervals. One end of the column 20 is fixedly mounted on the end of the lower cover 103 away from the back plate 105, and the other end passes through the end of the upper cover 101 away from the back plate 105. The lower cover 103 forms the base of the column 20. The upper cover 101 is rotatably mounted on the upper end of the back plate 105 by a hinge or the like, that is, the upper cover 101 can be folded upward relative to the back plate 105. An inverted "L"-shaped reinforcement component 107 and a straight "L"-shaped reinforcement component 107 are respectively provided at the upper and lower four corners of the inner wall of the fixed bracket 10. An opening 109 is formed on the side of the fixed bracket 10 opposite to the back plate 105. In addition, a through hole 1011 is further provided at the front end of the upper cover 101 near the opening 109 for the upper end of the column 20 to pass through. The through hole 1011 is a hole structure with an opening on one side to facilitate the column 20 to enter the through hole 1011 through the opening. The shape of the through hole 1011 can be circular, square, etc., as long as it is convenient for installing the column 20.

[0018] The column 20 is a rod-shaped structure typically made of stainless steel. The lower end of the column 20 is fixed to the lower cover 103 of the fixed bracket 10. The upper end of the column 20 passes through the through-hole 1011 of the upper cover 101 and protrudes upward from the upper cover 101. Male threads are formed on the outer wall of the upper half of the column 20 to threadably engage with the locking ring 50.

[0019] The guide wheel 30 has a hollow hole (not shown) formed in its center along its longitudinal axis. The pillar 20 extends through the hole, allowing the guide wheel 30 to rotatably fit around the periphery of the pillar 20. The guide wheel 30 has a roughly rectangular cross-section along its longitudinal direction, with a smooth outer wall that contacts the glass sheet. The guide wheel 30 is typically made of polyetheretherketone (PEEK). Alternatively, the guide wheel 30 can be made entirely of PEEK or have an inner layer of PEEK and an outer layer coated with PU adhesive.

[0020] The sliding block 40 is a rectangular, cube-shaped, or circular block with a central hole. It is mounted on the column 20. The sliding block 40 can slide up and down relative to the column 20 by external force applied by the operator. In this embodiment, the sliding block 40 is preferably circular, with a diameter smaller than that of the guide wheel 30. Furthermore, the height of the guide wheel 30 can be adjusted by manually adding or removing the sliding blocks 40.

[0021] The inner surface of the locking ring 50 is formed with a female thread that mates with the male thread on the upper end of the column 20. By meshing the female and male threads, the locking ring 50 can be screwed downward and tightened until its lower end tightly abuts the upper surface of the upper cover plate 101. The locking ring 50 serves to stably secure the upper end of the column 20 to the fixing bracket 10.

[0022] In this embodiment, there are multiple sliding blocks 40. A portion of the sliding blocks 40 is positioned below the guide wheel 30 to support and elevate the guide wheel 30, while another portion of the sliding blocks 40 is supported on the upper surface of the guide wheel 30 and fills the space between the upper surface of the guide wheel 30 and the upper cover 101. The sliding blocks 40 above the guide wheel 30 stabilize the rotation of the guide wheel 30, preventing the guide wheel 30 from tilting or shaking during rotation, thereby preventing damage to the glass sheet in contact with it.

[0023] In the guide mechanism 100 of the glass washing machine of the present invention, when a glass sheet is being conveyed by the conveying device, the two side edges of the glass sheet contact the outer circumference of the guide wheel 30 and slide forward along the outer circumference, driving the guide wheel 30 to rotate during the sliding process. Over time, the glass sheet causes the sidewalls of the guide wheel 30 to be scratched by friction. When the scratches reach a certain depth, they can easily cause the glass sheet to break. In this case, the guide wheel 30 can be raised by increasing the number of sliding blocks 40 located below the guide wheel 30.

[0024] Specifically, see Figure 1 (a)~(e). Figure 1 (a) is a cross-sectional view of the guide mechanism 100 of the glass washing machine according to the present invention when the guide wheel 30 is in the first position during use; at this time, a stress point A is formed between the glass sheet G and the side wall of the guide wheel 30 . Figure 1 (b) is Figure 1 (a) is a schematic diagram of the guide wheel 30 being raised and the glass piece G contacting the contact point B on the guide wheel 30 ; at this time, a first dent is formed on the side wall of the guide wheel 30 . Figure 1 (c) is Figure 1 (b) shows a schematic diagram of the guide wheel 30 after being raised again; at this time, a second dent is formed on the side wall of the guide wheel 30. Figure 1(d) is Figure 1 (c) shows a schematic diagram of the guide wheel 30 after being raised again; at this time, a third indentation is formed on the side wall of the guide wheel 30. Figure 1 (e) is Figure 1 (d) is a schematic diagram of a guide wheel in a discarded state.

[0025] In this embodiment, Figure 1 As shown in (a), when used for the first time, two sliding pads 40 are provided below the guide wheel 30, and four sliding pads 40 are provided between the upper surface of the guide wheel 30 and the lower surface of the upper cover 101. The glass piece G contacts point A (stress point) on the outer peripheral surface of the guide wheel 30. After a period of use, a dent is generated on the outer peripheral surface of the guide wheel 30 due to the sliding friction of the glass piece. At this time, the operator can rotate the locking ring 50 and remove it, and then flip the upper cover 101 upward (towards the rear of the back plate 105) to open the upper cover 101, and then remove the guide wheel 30 on the outer periphery of the column 20 and the four sliding pads 40 above it, and add a sliding pad 40 (as shown in FIG. 1 ) on the basis of the two sliding pads 40 on the lower cover 103. Figure 1 (b)). Afterwards, the operator re-installs the guide wheel 30 on the outer periphery of the column 20 and places three sliding blocks 40 above the guide wheel 30. That is, when the height of the opening 109 of the fixed bracket 10 remains unchanged, for every additional sliding block 40 below the guide wheel 30, one sliding block 40 above the guide wheel 30 needs to be reduced accordingly. Figure 1 As shown in (b), after the glass sheet G is raised, the contact point between the glass sheet G and the guide wheel 30 changes. Specifically, at this time, the glass sheet G will contact the contact point B slightly below the first indentation on the outer surface of the guide wheel 30. After a period of use, a second indentation will be generated on the circumference of the contact point B (as shown in FIG. Figure 1 (c)). When the depth of the second dent reaches the specified level, the guide wheel 30 and the sliding pad 40 above it can be disassembled using the same method as above, and the number of sliding pads 40 below the guide wheel 30 can be increased based on the previous method, while the number of sliding pads 40 above the guide wheel 30 can be reduced accordingly. After the third dent is generated on the outer surface of the guide wheel 30 (as shown in FIG. Figure 1 As shown in (d), repeat the above method to change the number of upper and lower sliding pads 40 of the guide wheel 30. Generally, when the length of the longitudinal connecting line of the dent exceeds two-thirds of the height of the guide wheel 30, it is possible to consider replacing the guide wheel 30, that is, scrapping the guide wheel 30 (such as Figure 1 (e)).

[0026] In summary, after repeated use, the guide wheel 30 will develop dents on its outer surface. In this case, the guide wheel 30 needs to be raised to change the stress point where it contacts the glass sheet. However, the force applied to the guide wheel 30 is tilted, and over time, the column 20 may become skewed or bent due to the force. The present invention secures the column 20 with a U-shaped fixing bracket 10. This two-point fixing bracket 10 effectively mitigates the effects of excessive stress on the column 20. Furthermore, the upper cover 101 of the U-shaped fixing bracket 10 is provided with a through hole and can be flipped relative to the back plate 105, greatly facilitating the assembly and disassembly of the column 20 and saving replacement time. In other words, the present invention introduces the concept of adjustability to a previously disposable consumable (guide wheel), significantly extending its service life and thus reducing costs. The replacement cycle of the guide wheel 30 is directly related to the height of the guide wheel 30 itself and the height of the sliding pad 40. Evaluation shows that the service life of each guide wheel 30 can be extended by three times.
