Description

Technical Field

[0001] The present invention relates to the technical field of liquid crystal glass substrate equipment detection, and particularly relates to a detection device for the rollers of a edge roller machine. Background Art

[0002] The overflow down-draw method is an advanced process technology for manufacturing high-quality flat glass. During the production of liquid crystal glass using the overflow down-draw method, the edge roller machine plays a key role in controlling the size, shape, thickness uniformity, and surface quality of the product, and is one of the important devices for ensuring the production of high-quality substrate glass.

[0003] When the edge roller machine is working, the rollers of the edge roller machine rotate at a certain speed and release the edge of the glass ribbon. The frictional force and traction force generated by the clamping and rotation of the rollers of the edge roller machine act on the glass ribbon to make the glass ribbon descend at a uniform speed.

[0004] Due to the fact that the rollers of the edge roller machine may be affected by many factors such as material properties, processing and manufacturing processes, and air bubbles and impurities, when the rollers of the edge roller machine enter the furnace and are affected by high temperature, there may be a deviation from the desired effect of the designer, and it is difficult to evaluate the clamping state of the rollers, which may lead to uneven thickness of the glass ribbon, uneven internal stress, or the appearance of wrinkles and corrugations, thus affecting the quality of the glass ribbon. Therefore, a detection device for detecting the clamping state of the rollers is provided to solve the above problems. Summary of the Invention

[0005] To solve the technical problems existing in the above background art, the present invention proposes a detection device for the rollers of an edge roller machine.

[0013] The second pointer assembly is mounted on the plate body, and a second transmission gear meshing with the second sector gear plate is coaxially arranged on the pointer shaft of the second pointer assembly;

[0014] Wherein, when the first clamping assembly and the second clamping assembly are driven by the first roller shaft and the second roller shaft to slide towards each other along the guiding groove, the deformation of the U-shaped spring tube drives the first link mechanism and the second link mechanism to act, respectively causing the first sector gear plate to drive the first pointer assembly to rotate and the second sector gear plate to drive the second pointer assembly to rotate, and displaying the corresponding clamping force value on the scale dial.

[0015] Preferably, the first clamping assembly includes a first Y-shaped push rod and a first roller provided at its branch end;

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] Compared with the prior art, by combining mechanical transmission with the deformation of the bourdon tube, high-precision measurement of the clamping force during the rotation of the roller shaft is achieved, and whether the clamping state of the roller shaft on the edge roller is abnormal can be detected in real time; moreover, the Y-shaped push rod structure is used to achieve line contact with the roller shaft in the rotating state, which can ensure that the acting force between the Y-shaped push rod structure and the roller shaft always passes through the center of the roller shaft, thereby ensuring the balance of the roller shaft and making the measurement result more accurate; and through the mounting frame and the fine-tuning components on the mounting frame, the overall detection device can adapt to different working conditions.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] As Figures 1 - 6 shown, this embodiment provides a detecting device for the roller shaft of a edge pulling machine, which is used to detect the clamping force between two roller shafts on the edge pulling machine. It is characterized by including:

[0034] A plate body 5, the plate body 5 is arranged between the first roller shaft 1 and the second roller shaft 2. A guiding groove 51 is horizontally formed on the plate body 5, and a dial 10 is installed on the plate body 5;

[0035] A first clamping assembly, the first slider 71 of the first clamping assembly is adaptively installed in the guiding groove 51 of the plate body 5, and the first clamping assembly can slide along the path of the guiding groove 51;

[0036] A second clamping assembly, the second slider 131 of the second clamping assembly is adaptively installed in the guiding groove 51 of the plate body 5, and the second clamping assembly can slide along the path of the guiding groove 51;

[0037] A U-shaped spring tube 9, the U-shaped spring tube 9 is installed on the plate body 5. One end of the U-shaped spring tube 9 is connected to the first sector gear plate 23 through a first link mechanism, and the other end of the U-shaped spring tube 9 is connected to the second sector gear plate 24 through a second link mechanism;

[0038] A first pointer assembly, the first pointer assembly is installed on the plate body 5, and a first transmission gear 25 meshing with the first sector gear plate 23 is coaxially arranged on the pointer shaft of the first pointer assembly;

[0039] A second pointer assembly, the second pointer assembly is installed on the plate body 5, and a second transmission gear meshing with the second sector gear plate 24 is coaxially arranged on the pointer shaft of the second pointer assembly;

[0040] Wherein, when the first clamping assembly and the second clamping assembly are driven by the first roller shaft 1 and the second roller shaft 2 to slide towards each other along the guiding groove 51, the deformation of the U-shaped spring tube 9 drives the first link mechanism and the second link mechanism to act, respectively enabling the first sector gear plate 23 to drive the first pointer assembly to rotate and the second sector gear plate 24 to drive the second pointer assembly to rotate, and displaying the corresponding clamping force value on the dial 10.

[0041] Overall, the detection device is installed between the first roller 1 and the second roller 2, and the first clamping assembly is abutted against the first roller 1, and the second clamping assembly is abutted against the second roller 2. Through the movement of the first roller 1 and the second roller 2, the first clamping assembly and the second clamping assembly are pushed to slide towards each other along the guide groove 51. The first slider 71 and the second slider 131 squeeze the U-shaped spring tube 9 to deform. The deformations at both ends of the U-shaped spring tube 9 are converted into rotational movements of the first sector gear 23 and the second sector gear 24 through the first link mechanism and the second link mechanism. Since the first sector gear 23 meshes with the first transmission gear 25, the first pointer assembly deflects, and the second sector gear 24 meshes with the second transmission gear, the second pointer assembly deflects. By rotating the first pointer assembly and the second pointer assembly, the clamping forces generated by the first roller 1 and the second roller 2 can be respectively displayed.

[0042] As Figure 1 , Figure 3 , Figure 4 and Figure 6 shown, in this embodiment, the first clamping assembly includes a first Y-shaped push rod 7 and a first roller 8 provided at its branched end;

[0043] The second clamping assembly includes a second Y-shaped push rod 13 and a second roller 141 provided at its branched end.

[0044] Specifically, the first clamping assembly includes a first Y-shaped push rod 7 and a first roller 8 provided at its branched end, and the second clamping assembly includes a second Y-shaped push rod 13 and a second roller 141 provided at its branched end. By forming a line contact between the roller and the roller shaft, while maintaining the balance of force, the friction formed between the two can also be reduced, and the accuracy of the detected clamping force can be improved.

[0045] As Figure 1 and Figure 5 shown, in this embodiment, the first link mechanism includes a first rotating frame 20 hinged to the plate body 5, one end of which is hinged to the end of the U-shaped spring tube 9 through a first connecting rod 19, and the other end is fixedly connected to the first sector gear 23;

[0046] The second link mechanism includes a second rotating frame 22 hinged to the plate body 5, one end of which is hinged to the other end of the U-shaped spring tube 9 through a second connecting rod 21, and the other end is fixedly connected to the second sector gear 24.

[0047] Specifically, when the first slider 71 and the second slider 131 move towards each other along the guide groove 51, the two ends of the U-shaped bellows 9 are deformed. The first connecting rod 19 drives the first rotating frame 20 to rotate, causing the first sector gear plate 23 to drive the first transmission gear 25 to rotate, and further causing the first pointer 11 to deflect. Similarly, the second connecting rod 21 drives the second rotating frame 22 to rotate, causing the second sector gear plate 24 to drive the second transmission gear to rotate, and further causing the second pointer 12 to deflect. At this time, the real-time clamping force values of the first roller shaft 1 and the second roller shaft 2 are displayed on the dial 10.

[0048] As Figure 1 and Figure 5 shown, in this embodiment, hairsprings 26 are provided on the pointer shafts of the first pointer assembly and the second pointer assembly. One end of the hairspring 26 is fixed to the pointer shaft, and the other end is fixed to the mounting post 52 of the plate body 5.

[0049] By providing the hairsprings 26, the reset of the first pointer 11 and the second pointer 12 can be realized, and the tiny gap between the first transmission gear 25 and the second transmission gear can be eliminated, reducing the error between the first pointer 11 and the second pointer 12.

[0050] As Figures 1 - 2 shown, in this embodiment, a first scale line 101 and a second scale line 102 are further provided on the dial 10. The first scale line 101 and the second scale line 102 respectively correspond to the movement tracks of the first pointer assembly and the second pointer assembly.

[0051] Specifically, by providing the first scale line 101 and the second scale line 102 on the movement tracks of the first pointer 11 and the second pointer 12 respectively, the deviation value of the clamping force of the first roller shaft 1 and the second roller shaft 2 can be more clearly compared, facilitating the adjustment of subsequent equipment.

[0052] As Figures 3 - 4 shown, in this embodiment, it further includes a mounting frame 3 with adjustable height. The mounting frame 3 includes a cross beam connected to the edge puller and a column provided with a vertical slide rail. The plate body 5 is fixed to different height positions of the column by screws 6.

[0053] By providing the mounting frame 3 with adjustable height, the horizontal sections of the first Y-shaped push rod 7 and the second Y-shaped push rod 13 are adjusted to be flush with the axes of the first roller shaft 1 and the second roller shaft 2 in height. By adjusting the horizontal sections, it can be ensured that the first roller 8 is symmetric about the axis of the first roller shaft 1, and the second roller 141 is symmetric about the axis of the second roller shaft 2, enabling the first Y-shaped push rod 7 and the second Y-shaped push rod 13 to be more balanced in force.

[0054] Specifically: by moving the installation frame 4 along the direction of the column of the installation rack 3, the lifting adjustment of the plate body 5 is realized. After the lifting adjustment of the plate body 5 is completed, the fixing between the installation frame 4 and the column is realized by tightening the screw 6.

[0055] As Figures 3 - 4 shown, in this embodiment, the installation rack 3 is provided with a fine adjustment component, which includes a knob 15, an adjustment gear 17 coaxially arranged with the knob 15, and a rack 18 consistent with the extending direction of the column. The adjustment gear 17 meshes with the rack 18.

[0056] By rotating the knob 15 to realize the rotation of the adjustment gear 17, through the meshing between the adjustment gear 17 and the rack 18, the adjustment block 16 can be lifted and lowered along the direction parallel to the column to drive the plate body 5 to rotate, and finally the fine adjustment of the height of the plate body 5 is realized, which can make the adjustment accuracy of the first Y-shaped push rod 7 and the second Y-shaped push rod 13 higher, so as to improve the overall detection accuracy of the device.

[0057] Of course, for those skilled in the art, the present invention is not limited to the details of the above exemplary embodiments, but also includes the same or similar structures that can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
