[0001] The present invention relates to the technical field of carrier glass manufacturing, and particularly to a method for detecting the position of carrier glass and an overflow down-draw forming device. Background Art

[0002] The surface of the carrier glass produced by the overflow down-draw process has good planar smoothness because it only contacts the air. During the production process of the overflow down-draw method, the carrier glass overflows from the overflow brick, is stretched to the required thickness by the traction roller, then cut into the size required by the user by the cutting mechanism, and finally the breaking mechanism adsorbs the carrier glass by the suction cup and breaks it along the cutting line to form the final glass product.

[0003] During the production process of the above-mentioned carrier glass, factors such as the position change of the traction roller of the overflow down-draw forming device due to vibration and the springback of the cut carrier glass will cause the shape of the carrier glass to change, making the carrier glass not in the same plane at the three positions of the traction roller, the cutting mechanism, and the breaking mechanism, resulting in the carrier glass shaking and twisting and generating new mechanical stress, which affects the stability of the quality of the carrier glass. Summary of the Invention

[0013] S6: Adjust the position of the carrier glass at the breaking mechanism along the Z direction so that the carrier glass at the breaking mechanism is aligned with the two third detection blocks.

[0014] As a preferred solution, a first hole is provided through the detection block along the X direction, and the spacing of the first hole along the Z direction is equal to the thickness of the carrier glass;

[0015] In step S2, by adjusting the position of the two first detection blocks along the Z direction, the first hole of the first detection block is aligned with the carrier glass at the traction roller.

[0016] As a preferred solution, in step S4, the carrier glass at the cutting mechanism is aligned with the first hole of the second detection block after position adjustment;

[0017] In step S6, the carrier glass at the breaking mechanism is aligned with the first hole of the third detection block after position adjustment.

[0018] As a preferred solution, in steps S2, S4 and S6, the first holes of the detection blocks and the carrier glass at the corresponding positions are irradiated along the X direction by laser rays respectively to detect whether the first holes of the detection blocks and the carrier glass at the corresponding positions are aligned.

[0019] As a preferred solution, a second hole is provided through the detection block along the Y direction, the first hole and the second hole are in the same plane in the Z direction, and the X direction, the Y direction and the Z direction are perpendicular to each other in pairs;

[0020] In step S3, the second holes of the two second detection blocks after position adjustment are aligned with the second holes of the two first detection blocks one by one;

[0027] The beneficial effects of the present invention are:

[0028] The position detection method of the carrier glass proposed by the present invention is to install a detection block on each of the two sides along the X direction at the traction roller, cutting mechanism, and breaking mechanism. First, taking the carrier glass at the traction roller as a reference, adjust the positions of the two first detection blocks along the Z direction so that the first detection blocks are aligned with the carrier glass at the traction roller. Then, taking the first detection block as a reference, adjust the positions of the second detection blocks along the Z direction so that the two second detection blocks are in the same plane as the two first detection blocks in the Z direction. Then, taking the second detection block as a reference, adjust the position of the carrier glass at the cutting mechanism along the Z direction so that the carrier glass at the cutting mechanism is aligned with the two second detection blocks. Finally, taking the second detection block as a reference, adjust the positions of the third detection blocks along the Z direction so that the two third detection blocks are in the same plane as the two second detection blocks in the Z direction. Finally, taking the third detection block as a reference, adjust the position of the carrier glass at the breaking mechanism along the Z direction so that the carrier glass at the breaking mechanism is aligned with the two third detection blocks. The position detection method of the carrier glass takes the position of the carrier glass at the traction roller along the Z direction as a reference, and adjusts the positions of the carrier glasses at the cutting mechanism and the breaking mechanism along the Z direction respectively through the detection blocks, so that the three positions of the carrier glass at the traction roller, cutting mechanism, and breaking mechanism are all in the same plane, avoiding the shaking and distortion of the carrier glass and improving the quality of the carrier glass.

[0029] The overflow down-draw forming equipment proposed by the present invention adopts the above-mentioned position detection method of the carrier glass. Taking the position of the carrier glass at the traction roller along the Z direction as a reference, it adjusts the positions of the carrier glasses at the cutting mechanism and the breaking mechanism along the Z direction respectively through the detection blocks, so that the three positions of the carrier glass at the traction roller, cutting mechanism, and breaking mechanism are all in the same plane, avoiding the shaking and distortion of the carrier glass and improving the quality of the carrier glass.

It can be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Additionally, it should be noted that for the sake of description, only parts related to the present invention are shown in the drawings rather than all of them.

[0043] The technical solution of the present invention will be further described below in conjunction with the drawings and through specific embodiments.

[0044] As Figure 1 shown, this embodiment proposes an overflow down-draw forming device to produce carrier glass 10 through the overflow down-draw process. Specifically, the overflow down-draw forming device includes a frame (not shown in the figure) and a traction roller 1, a cutting mechanism 2, and a breaking mechanism 3 arranged on the frame in sequence along the Y direction. The two traction rollers 1 are arranged oppositely and rotate in opposite directions to stretch the overflowing carrier glass 10 to the required thickness. The cutting mechanism 2 includes an anvil 21 and a cutter 22. The anvil 21 and the cutter 22 are arranged on both sides of the carrier glass 10 in the thickness direction, so that when the cutter 22 scribes and cuts on the carrier glass 10, the anvil 21 can provide good support. After the carrier glass 10 is scribed and cut, it continues to move to the breaking mechanism 3. The breaking mechanism 3 includes a bracket and suction cups. A plurality of suction cups are evenly distributed on the bracket, and the distribution range of the suction cups is approximately equal to the scribed and cut range of the carrier glass 10, so that a plurality of suction cups evenly adsorb on the carrier glass 10, and then the adsorbed carrier glass 10 is broken along the cutting line by the flipping action of the bracket to form glass products.

[0045] Furthermore, the overflow down-draw forming device further includes an upper guiding part 6 and a lower guiding part 7 installed on the frame. Both the upper guiding part 6 and the lower guiding part 7 are a plurality of roller wheels, and the plurality of roller wheels are installed on the roller shaft at intervals along the X direction. The upper guiding part 6 is adjacent to the cutting mechanism 2, and the lower guiding part 7 is adjacent to the breaking mechanism 3. Both the upper guiding part 6 and the lower guiding part 7 play a guiding and supporting role for the carrier glass 10. At the same time, both the upper guiding part 6 and the lower guiding part 7 can be displaced relative to the frame along the Z direction to adjust the position of the carrier glass 10 at the corresponding position along the Z direction.

[0046] During the production process of the above-mentioned carrier glass 10, various factors such as the position change of the traction roller 1 of the overflow down-draw forming device caused by vibration and the springback of the cut carrier glass 10 will cause the shape of the carrier glass 10 to change, resulting in the carrier glass 10 not being in the same plane at the three positions of the traction roller 1, the cutting mechanism 2, and the breaking mechanism 3, causing the carrier glass 10 to shake and twist and generating new mechanical stress, affecting the stability of the quality of the carrier glass 10.

[0047] To solve the above problems, as Figure 1 shown, the overflow down-draw forming device further includes at least six detection blocks 4. By dividing the six detection blocks 4 into three groups in pairs, two detection blocks 4 in the first group are respectively installed on both sides of the traction roller 1 along the X direction (the width direction of the carrier glass 10), two detection blocks 4 in the second group are respectively installed on both sides of the cutting mechanism 2 along the X direction, and two detection blocks 4 in the third group are respectively installed on both sides of the breaking mechanism 3 along the X direction. Through the six detection blocks 4, the carrier glass 10 is in the same plane at three positions, namely, at the traction roller 1, at the cutting mechanism 2, and at the breaking mechanism 3.

[0048] As Figure 2 shown, the three detection blocks 4 on the same side in the X direction are installed on the frame at intervals along the same straight line in the Y direction through a mounting bracket (not shown in the figure), so as to realize the positioning installation of the detection blocks 4, without the need for position adjustment in the X direction and the Y direction, improving the adjustment efficiency.

[0049] As Figure 3 shown, this embodiment also proposes a method for detecting the position of the carrier glass. The overflow down-draw forming device makes the carrier glass 10 in the same plane at three positions, namely, at the traction roller 1, at the cutting mechanism 2, and at the breaking mechanism 3, through the method for detecting the position of the carrier glass provided in this embodiment.

[0050] Specifically, the method for detecting the position of the carrier glass includes the following steps:

[0051] S1: One detection block 4 is respectively installed on both sides in the X direction at the traction roller 1, the cutting mechanism 2, and the breaking mechanism 3 through which the carrier glass 10 passes in sequence, and the detection block 4 is adjustable in position along the Z direction;

[0052] S2: Adjust the position of the first detection block 4 on both sides of the traction roller 1 along the Z direction so that the two first detection blocks 4 are aligned with the carrier glass 10 at the traction roller 1;

[0053] S3: Adjust the position of the second detection block 4 on both sides of the cutting mechanism 2 along the Z direction so that the two second detection blocks 4 are in the same plane as the two first detection blocks 4 in the Z direction;

[0054] S4: Adjust the position of the carrier glass 10 at the cutting mechanism 2 along the Z direction so that the carrier glass 10 at the cutting mechanism 2 is aligned with the two second detection blocks 4;

[0055] S5: Adjust the position of the third detection block 4 on both sides at the breaking mechanism 3 along the Z direction so that the two third detection blocks 4 are in the same plane as the two second detection blocks 4 in the Z direction;

[0056] S6: Adjust the position of the carrier glass 10 at the breaking mechanism 3 in the Z direction so that the carrier glass 10 at the breaking mechanism 3 is aligned with the two third detection blocks 4.

[0057] By installing a detection block 4 on each side in the X direction at the traction roller 1, the cutting mechanism 2, and the breaking mechanism 3, first adjust the positions of the two first detection blocks 4 in the Z direction with the carrier glass 10 at the traction roller 1 as the reference so that the first detection blocks 4 are aligned with the carrier glass 10 at the traction roller 1. Then, with the first detection block 4 as the reference, adjust the position of the second detection block 4 in the Z direction so that the two second detection blocks 4 are in the same plane in the Z direction as the two first detection blocks 4. Then, with the second detection block 4 as the reference, adjust the position of the carrier glass 10 at the cutting mechanism 2 in the Z direction so that the carrier glass 10 at the cutting mechanism 2 is aligned with the two second detection blocks 4. Finally, with the second detection block 4 as the reference, adjust the position of the third detection block 4 in the Z direction so that the two third detection blocks 4 are in the same plane in the Z direction as the two second detection blocks 4. Finally, with the third detection block 4 as the reference, adjust the position of the carrier glass 10 at the breaking mechanism 3 in the Z direction so that the carrier glass 10 at the breaking mechanism 3 is aligned with the two third detection blocks 4. The position detection method of the carrier glass is based on the position of the carrier glass 10 at the traction roller 1 in the Z direction, and adjusts the positions of the carrier glass 10 at the cutting mechanism 2 and the breaking mechanism 3 in the Z direction through the detection block 4 respectively, so that the three positions of the carrier glass 10 at the traction roller 1, the cutting mechanism 2, and the breaking mechanism 3 are all in the same plane, avoiding the shaking and distortion of the carrier glass 10 and improving the quality of the carrier glass 10.

[0058] As Figure 4 shown, the detection block 4 is provided with a first hole 41 penetrating in the X direction, and the spacing of the first hole 41 in the Z direction is equal to the thickness of the carrier glass 10. The detection block 4 is provided with a second hole 42 penetrating in the Y direction, and the first hole 41 and the second hole 42 are in the same plane in the Z direction, and the X direction, the Y direction, and the Z direction are perpendicular to each other in pairs. Specifically, the detection block 4 is a square tube, and a first hole 41 is provided on each of the two side walls of the detection block 4 in the X direction, and a second hole 42 is provided on each of the two side walls of the detection block 4 in the Y direction.

[0059] It should be noted that the detection block 4 adjusts the coordinate of the detection block 4 in the Z direction through the mounting bracket. When the detection block 4 is aligned with the carrier glass 10, the first hole 41 is disposed opposite to the side surface of the carrier glass 10 in the X direction, and the projection of the first hole 41 in the X direction completely falls on the corresponding side surface of the carrier glass 10 in the X direction. Since the first hole 41 and the second hole 42 are in the same plane in the Z direction, the first hole 41 and the second hole 42 have the same position in the Z direction, that is, the same Z-direction coordinate. When the first hole 41 is aligned with the carrier glass 10 at the corresponding position, the second hole 42 is also aligned with the carrier glass 10 at the corresponding position.

[0060] In step S2, the positions of the two first detection blocks 4 in the Z direction are adjusted so that the first hole 41 of the first detection block 4 is aligned with the carrier glass 10 at the traction roller 1. Based on the carrier glass 10 at the traction roller 1, the detection blocks 4 on both sides of the traction roller 1 in the X direction are adjusted in place. Specifically, the detection block 4 can adjust the two first detection blocks 4 in place by adjusting the mounting bracket. Since the mounting bracket is a prior art, it only needs to be able to adjust the position of the detection block 4 in the Z direction, and the specific structure and adjustment process of the mounting bracket will not be described in detail.

[0061] Further, in step S3, the second holes 42 of the two second detection blocks 4 after position adjustment are aligned with the second holes 42 of the two first detection blocks 4 one by one. Based on the first detection block 4 adjusted in place, the position of the second detection block 4 in the Z direction is adjusted in place. At this time, the positions of the four first holes 41 and the four second holes 42 in the first detection block 4 and the second detection block 4 are equal in the Z direction. By analogy, in step S5, the second holes 42 of the two third detection blocks 4 after position adjustment are aligned with the second holes 42 of the two second detection blocks 4 one by one. Based on the second detection block 4 adjusted in place, the position of the third detection block 4 in the Z direction is adjusted in place. At this time, the positions of all the first holes 41 and all the second holes 42 in the six detection blocks 4 are equal in the Z direction.

[0062] In step S4, the carrier glass 10 at the cutting mechanism 2 is aligned with the first hole 41 of the second detection block 4 after position adjustment. At this time, the carrier glass 10 at the cutting mechanism 2 and the carrier glass 10 at the traction roller 1 have the same position in the Z direction, that is, they are in the same plane in the Z direction. Further, in step S6, the carrier glass 10 at the breaking mechanism 3 is aligned with the first hole 41 of the third detection block 4 after position adjustment. At this time, the carrier glass 10 at the breaking mechanism 3 and the carrier glass 10 at the cutting mechanism 2 have the same position in the Z direction, that is, they are in the same plane in the Z direction, so that the carrier glass 10 is in the same plane in the Z direction at the three positions of the traction roller 1, the cutting mechanism 2, and the breaking mechanism 3.

[0063] Further, as Figure 5 and Figure 6 shown, the overflow down-draw forming device further includes a laser emitter 5, which can emit laser rays to irradiate the first holes 41 of the detection blocks 4 and the carrier glass 10 at corresponding positions along the X direction; alternatively, the laser emitter 5 irradiates the second holes 42 of three detection blocks 4 located on the same side in the X direction along the Y direction. Since the laser rays have the characteristics of concentrated direction, single color and high brightness, it is convenient to visually check whether the first holes 41 of the first detection block 4 are aligned with the carrier glass 10 at the traction roller 1, which is beneficial to improving the adjustment accuracy.

[0064] In steps S2, S4 and S6, the first holes 41 of the detection blocks 4 and the carrier glass 10 at corresponding positions are irradiated along the X direction by laser rays respectively to detect whether the first holes 41 of the detection blocks 4 are aligned with the carrier glass 10 at corresponding positions. Specifically, hold the laser emitter 5 and irradiate the first holes 41 of the first detection block 4 along the X direction. If the laser rays can completely irradiate the corresponding side surfaces of the carrier glass 10 at the traction roller 1 along the X direction after passing through the two first holes 41 of the first detection block 4, it means that the first holes 41 are aligned with the carrier glass 10. And so on, the laser emitter 5 can be held to irradiate the first holes 41 of the second detection block 4 and the first holes 41 of the third detection block 4 along the X direction in turn.

[0065] Further, in steps S3 and S5, the second holes 42 of three detection blocks 4 located on the same side in the X direction are irradiated along the Y direction by laser rays to detect whether the second holes 42 of three detection blocks 4 located on the same side in the X direction are aligned. Hold the laser emitter 5 and emit laser rays along the Y direction. Taking the second hole 42 of one of the first detection blocks 4 as a reference, adjust the positions of the second holes 42 of the second detection block 4 and the second holes 42 of the third detection block 4 located on one side in the X direction along the Z direction, so that the laser rays passing through the second hole 42 of the first detection block 4 can completely and unobstructedly pass through the second holes 42 of the second detection block 4 and the second holes 42 of the third detection block 4 on the same side. Repeat the above operation to adjust the second holes 42 of the second detection block 4 and the second holes 42 of the third detection block 4 located on one side in the X direction in place along the Z direction.

[0066] As Figure 1As shown, in step S4, the position of the carrier glass 10 at the cutting mechanism 2 in the Z direction is adjusted by the upper guiding portion 6 disposed adjacent to the cutting mechanism 2. In step S6, the position of the carrier glass 10 at the breaking mechanism 3 in the Z direction is adjusted by the lower guiding portion 7 disposed adjacent to the breaking mechanism 3. By adjusting the positions of the upper guiding portion 6 and the lower guiding portion 7 relative to the machine frame in the Z direction, a supporting force can be applied to the carrier glass 10 at the corresponding position, so as to adjust the position of the carrier glass 10 at the corresponding position in the Z direction respectively, making full use of the original components of the overflow down-draw forming equipment, without the need to additionally increase an adjusting mechanism, simplifying the structure and reducing the cost of the overflow down-draw forming equipment.
