Description

Technical Field

[0001] The utility model relates to the technical field of LCD glass substrate edge guide wheels, in particular to a protection mechanism for LCD glass substrate edge guide wheels. Background Art

[0002] At present, in the panel production industry, glass substrates are transported by conveying mechanisms. During the conveying process, in order to prevent the conveying trajectory of the glass substrate from deviating, guide wheels are set on both sides of the equipment of the conveying mechanism to guide and limit the trajectory, so that the glass substrate can be transported on the assembly line as required.

[0003] At present, during the conveying process of TFT LCD, the side guide wheel (Guide Roller) during the conveying of glass often causes glass breakage due to installation design reasons. At the same time, when the glass is conveyed at an angle of 5 degrees, the side guide wheel is worn. When the above problems occur, it is necessary to replace the new side guide wheel in time. However, such a solution increases the cost of operating consumables. Therefore, the present application proposes a protective mechanism for the side guide wheel of LCD glass substrate to solve the above problems. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides a protective mechanism for an edge guide wheel of an LCD glass substrate, which has the advantage of reducing replacement costs and solves the problem of wear of the edge guide wheel when the glass is tilted and transported.

[0005] To achieve the above object, the utility model provides the following technical solutions: a protective mechanism for an edge guide wheel of an LCD glass substrate, comprising an edge guide wheel base, two adjusting screws are installed on the upper surface of the edge guide wheel base, a support rod is threadedly connected on the upper surface of the edge guide wheel base and near the right end thereof, and an edge guide wheel body is fixed on the top end of the support rod;

[0006] The bottom of the side guide wheel base is slidably connected to the side guide wheel support frame, the outer side of the side guide wheel body is fixed with a shaft sleeve retaining spring, and the top end of the shaft sleeve retaining spring is fixed with a side wheel bearing sleeve.

[0007] Furthermore, a mounting groove is provided on the upper surface of the side guide wheel base.

[0008] Furthermore, the cross-sectional shape of the side guide wheel support frame is L-shaped.

[0009] Furthermore, the two adjusting screws are both inserted into the interior of the mounting slot.

[0010] Furthermore, the support rod is in the shape of a hexagonal stainless steel column.

[0011] Furthermore, the side guide wheel body is threadedly connected to the support rod via a fixing screw.

[0012] Furthermore, the two adjusting screws are threadedly connected to the upper surface of the side guide wheel support frame.

[0013] Furthermore, the two side wheel bearing sleeves are both UPE sleeves with a thickness of 2 mm.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] 1. The protection mechanism of the edge guide wheel of the LCD glass substrate is designed with a hexagonal stainless steel support rod with a diameter of 8 mm and a length of 80 to 120 mm. When the glass passes through the edge guide wheel body, the support rod will be slightly deformed due to the tilted gravity, thereby reducing the collision force between the contact glass and the external Guide Roller. The collision force when in contact with the glass is reduced according to the deformation and bending deformation, thereby reducing the purpose of fragmentation. When the edge of the glass rubs against the edge wheel bearing sleeve, the edge wheel bearing sleeve can be replaced after a certain period of operation. The cost of replacing the edge wheel bearing sleeve is much lower than that of the standard edge guide wheel body, thereby achieving the purpose of reducing loss.

[0016] 2. The protective mechanism of the edge guide wheel of the LCD glass substrate fixes the edge guide wheel support frame to the transmission unit area of ​​the external equipment, and adjusts the position of the edge guide wheel base by adjusting two adjustment screws, thereby achieving the purpose of changing the suitable width of the glass transmission, tightens the support rod and the edge guide wheel base by fixing screws, and then fixes the support rod and the edge guide wheel body by fixing screws.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1 to 3 In this embodiment, a protective mechanism for an edge guide wheel of an LCD glass substrate includes an edge guide wheel base 1. Two adjusting screws 3 are installed on the upper surface of the edge guide wheel base 1. A support rod 4 is threadedly connected to the upper surface of the edge guide wheel base 1 near its right end, and an edge guide wheel body 6 is fixed to the top of the support rod 4.

[0023] The bottom of the side guide wheel base 1 in this embodiment is slidably connected to the side guide wheel support frame 5, the outer side of the side guide wheel body 6 is fixed with a shaft sleeve retaining spring 8, the top of the shaft sleeve retaining spring 8 is fixed with a side wheel bearing sleeve 7, the side wheel bearing sleeve 7 and the shaft sleeve retaining spring 8 are fixed by bolts to facilitate subsequent replacement, and the side guide wheel support frame 5 is fixed to the transmission unit area of ​​the external equipment. By adjusting the two adjusting screws 3, the position of the side guide wheel base 1 is adjusted, thereby achieving the purpose of changing the suitable width of the glass transmission. The two side wheel bearing sleeves 7 are both UPE sleeves with a thickness of 2 mm.

[0024] In this example, a mounting groove 2 is provided on the upper surface of the side guide wheel base 1, and the cross-sectional shape of the side guide wheel support frame 5 is L-shaped.

The shape of the support rod 4 is a hexagonal stainless steel column, and the hexagonal stainless steel support rod 4 with a design diameter of eight millimeters and a length of eighty millimeters. To one hundred and twenty millimeters, when the glass passes through the side guide wheel body 6, due to the effect of the tilted gravity, the support rod 4 will be slightly deformed due to gravity, thereby reducing the force of contact with the glass, and the contact force with the glass is reduced according to the deformation and bending deformation, thereby reducing the purpose of fragmentation. The side guide wheel body 6 is threadedly connected to the support rod 4 by a fixing screw. When the glass passes through the friction with the side wheel bearing sleeve 7, the side wheel bearing sleeve 7 can be replaced after a certain period of operation. The cost of replacing the side wheel bearing sleeve 7 is much less than that of the standard side guide wheel body 6, thereby achieving the purpose of reducing loss. The two adjusting screws 3 are threadedly connected to the upper surface of the side guide wheel support frame 5.

[0025] It should be noted that the hexagonal stainless steel support rod 4 is designed to have a diameter of eight millimeters and a length of eighty to one hundred and twenty millimeters. When the glass passes through the side guide wheel body 6, due to the effect of the inclined gravity, the support rod 4 will be slightly deformed due to gravity, thereby reducing the force contacting the glass. The contact force with the glass is reduced according to the deformation and bending deformation, thereby reducing the purpose of fragmentation. When the glass passes through the friction with the side wheel bearing sleeve 7, the side wheel bearing sleeve 7 can be replaced after a certain period of operation. The cost of replacing the side wheel bearing sleeve 7 is much less than that of the standard side guide wheel body 6, thereby achieving the purpose of reducing losses.
