Description

Technical Field

[0001] The utility model relates to the technical field of glass detection, and specifically relates to a glass surface defect detection device. Background Art

[0002] In the field of glass manufacturing technology, after the glass is manufactured, it is usually necessary to detect glass defects. The method is to irradiate the glass to be detected with a light source, and then use an image acquisition device to collect the image of the irradiated area and send it to a processing unit for analysis to detect whether there are defects such as nodules, line channels, ripple marks, bubbles, and stones in the glass. The existing optical glass detection devices usually can only detect one side of the glass. When detecting the other side, it is necessary to manually flip the glass and then detect it again, which is rather troublesome and the detection efficiency is low.

[0003] After retrieval, the Chinese patent publication number is CN219065331U, which discloses an optical glass surface linear defect detection device. In this patent, the components in the moving assembly cooperate to drive the second U-shaped plate to move, which can make the transmission rollers on both sides squeeze the glass. Then, the components in the transmission assembly cooperate to drive the transmission rollers to drive the glass to move. Then, the detection plates on both sides are used to detect both sides of the glass simultaneously, so as to improve the detection efficiency.

[0004] However, when the above device is used, due to the setting of the groove structure, part of the glass to be detected inserted into the inner cavity of the groove cannot be detected, resulting in inaccurate overall glass detection. At the same time, when the transmission rollers on both sides squeeze the glass to be detected, if the thickness of the glass is relatively thin, it is difficult for the transmission rollers on both sides to effectively fix and drive the glass to move synchronously. If the glass thickness is relatively thick, it may be difficult to place it into the inner cavity of the groove. Content of the Utility Model

[0005] The utility model provides a glass surface defect detection device, which has the advantages of effectively fixing glass to be detected with different thicknesses and driving the glass to move synchronously, facilitating synchronous detection of both sides of the whole glass, and solving the problems of inability to effectively and stably fix glasses of different sizes and inability to detect some glasses.

[0006] Technical solution of the utility model: A glass surface defect detection device, including a bottom plate. On the left side of the top of the bottom plate, a side plate is fixedly installed. Inside the cavity of the side plate, a plurality of roller cylinders are detachably installed. A conveyor belt is wound around the outer surface of the roller cylinders. On the right front side of the top of the bottom plate, a control panel is fixedly installed. In the middle of the right side of the top of the bottom plate, a chute is opened. Inside the cavity of the chute, a sliding plate is movably installed. On the top of the sliding plate, a cross plate is fixedly installed. In the middle of the top of the cross plate, a right detection column is fixedly installed. In the middle of the right side of the bottom plate, a driving block is fixedly installed. In the middle of the left side of the driving block, a telescopic column is fixedly installed. On the top of both the side plate and the cross plate, a plurality of side columns are fixedly installed. On one side of the side columns, a rubber pad is fixedly installed. In the middle of the top of the side plate, a left detection column is fixedly installed.

[0007] Preferably, the control panel is electrically connected to all the roller cylinders and the driving block through wires. All the roller cylinders are evenly distributed on the left side inside the cavity of the side plate. On the top of the control panel, a plurality of buttons are fixedly installed. Thus, when in use, through different buttons on the top of the control panel, the start and stop of all the roller cylinders and the driving block are respectively controlled.

[0008] Preferably, the cross-sectional shape of the inside of the sliding plate matches the cross-sectional shape of the inside of the chute. The distance between the left side of the sliding plate and the left side inside the cavity of the chute when not working matches the distance between the left side column and the right side column when not working. Thus, during the use process, when the sliding plate moves leftward to the leftmost side inside the cavity of the chute, at this time, the right side column fits against the left side column. Furthermore, different thicknesses of glass can be effectively clamped and fixed during the use process.

[0009] Preferably, the driving block is connected to the right side of the sliding plate through the telescopic column passing through the bottom plate. The telescopic length of the telescopic column is greater than the width of the inside of the chute. Thus, when in use, the driving block starts to control the left and right movement of the telescopic column, thereby controlling the left and right movement of the sliding plate inside the cavity of the chute.

[0010] Preferably, the bottoms of the right detection column and the left detection column are at the same horizontal plane as the top surface of the conveyor belt. Both the left detection column and the right detection column are connected to an external display screen through wires. Thus, when in use, when the glass moves past the left detection column and the right detection column, the data generated by the detection is displayed through the external display screen.

[0011] Preferably, the side columns are distributed in a one-to-one correspondence on the front and rear sides of the top of the side plate and the cross plate. The side columns are evenly distributed on the front and rear sides of the left detection column and the right detection column.

[0012] Preferably, the rubber pad is made of synthetic rubber. The rubber pad is fixed on the opposite sides of the right detection column and the left detection column. The distance between the opposite sides of the left and right rubber pads is less than the distance between the right side of the side plate and the left side of the cross plate. Therefore, during use, by moving the cross plate to the left, the left and right rubber pads are made to closely adhere to the left and right sides of the glass to be detected. Combining with the material characteristics of the rubber pad, the friction with the glass to be detected is increased, thereby effectively fixing the glass to be detected.

[0013] Preferably, the heights of the left detection column and the right detection column are higher than the height of the side column. The heights of the left detection column and the right detection column are the same. The leftmost side column and the rightmost side column are both close to the left and right sides of the bottom plate. Therefore, during use, by utilizing the length of the bottom plate and the height of the left detection column, it is convenient to detect glass of a certain height and width.

[0014] The working principle and beneficial effects of the present utility model are as follows:

[0015] For this glass surface defect detection device, through the combined use of the side column structure and the rubber pad structure, when working, after placing the glass to be detected on the top of the conveyor belt, the cross plate, the right detection column, and the right side column move left synchronously, thereby stably clamping the glass to be detected. Combining with the large friction between the glass to be detected and the conveyor belt, the conveyor belt rotates to drive the glass to be detected to move backward. By making the bottoms of the left detection column and the right detection column be at the same horizontal plane as the top of the conveyor belt, the left and right sides of the glass to be detected on the top of the conveyor belt can be completely detected, achieving the effect of effectively fixing glass of different thicknesses to be detected and driving the glass to move synchronously, facilitating the synchronous detection of both sides of the overall glass.

Detailed implementation manners

[0022] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.

[0023] Please refer to Figures 1 to 4As shown in the figure, a glass surface defect detection device includes a bottom plate 1. On the left side of the top of the bottom plate 1, a side plate 2 is fixedly installed. A plurality of rollers 3 are detachably installed in the inner cavity of the side plate 2. A conveyor belt 4 is wound around the outer surface of the rollers 3. On the right front side of the top of the bottom plate 1, a control panel 5 is fixedly installed. In the middle of the right side of the top of the bottom plate 1, a chute 6 is opened. A sliding plate 7 is movably installed in the inner cavity of the chute 6. On the top of the sliding plate 7, a cross plate 8 is fixedly installed. In the middle of the top of the cross plate 8, a right detection column 9 is fixedly installed. In the middle of the right side of the bottom plate 1, a driving block 10 is fixedly installed. The control panel 5 is electrically connected to all the rollers 3 and the driving block 10 through wires. All the rollers 3 are evenly distributed on the left side of the inner cavity of the side plate 2. On the top of the control panel 5, a plurality of buttons are fixedly installed. Thus, when in use, through different buttons on the top of the control panel 5, the start and stop of all the rollers 3 and the driving block 10 are respectively controlled. In the middle of the left side of the driving block 10, a telescopic column 11 is fixedly installed. The driving block 10 is connected to the right side of the sliding plate 7 through the telescopic column 11 passing through the bottom plate 1. The telescopic length of the telescopic column 11 is greater than the width of the inner cavity of the chute 6. Thus, when in use, the driving block 10 starts to control the left and right movement of the telescopic column 11, thereby controlling the left and right movement of the sliding plate 7 in the inner cavity of the chute 6. On the tops of both the side plate 2 and the cross plate 8, a plurality of side columns 12 are fixedly installed. The cross-sectional shape of the inner cavity of the sliding plate 7 matches the cross-sectional shape of the inner cavity of the chute 6. The distance between the left side of the sliding plate 7 and the left side of the inner cavity of the chute 6 when not working matches the distance between the left side column 12 and the right side column 12 when not working. Thus, during the use process, when the sliding plate 7 moves to the leftmost side of the inner cavity of the chute 6, at this time, the right side column 12 fits against the left side column 12. Furthermore, during the use process, glasses of different thicknesses can be effectively clamped and fixed. On one side of the side column 12, a rubber pad 13 is fixedly installed. The rubber pad 13 is made of synthetic rubber material. The rubber pad 13 is fixed on the opposite sides of the right detection column 9 and the left detection column 14. The distance between the opposite sides of the left and right rubber pads 13 is less than the distance between the right side of the side plate 2 and the left side of the cross plate 8. Thus, during the use process, by moving the cross plate 8 to the left, the left and right rubber pads 13 are closely attached to the left and right sides of the glass to be detected. With the material characteristics of the rubber pad 13, the friction force with the glass to be detected is increased, thereby effectively fixing the glass to be detected. In the middle of the top of the side plate 2, a left detection column 14 is fixedly installed. The bottoms of the right detection column 9 and the left detection column 14 are at the same horizontal plane as the top surface of the conveyor belt 4. Both the left detection column 14 and the right detection column 9 are connected to an external display screen through wires. Thus, when in use, when the glass moves past the left detection column 14 and the right detection column 9, the data generated by the detection is displayed through the external display screen. The side columns 12 are distributed in the front and back sides of the tops of the side plate 2 and the cross plate 8 in one-to-one correspondence. The side columns 12 are evenly distributed on the front and back sides of the left detection column 14 and the right detection column 9. The heights of the left detection column 14 and the right detection column 9 are higher than the height of the side column 12. The heights of the left detection column 14 and the right detection column 9 are the same. The left side column 12 and the rightmost side column 12 are both close to the left side and the right side of the bottom plate 1. Thus, when in use,Utilize the length of the bottom plate 1 and the height of the left detection column 14 to facilitate the detection of glass with a certain height and width.

[0024] Working principle: During operation, place the glass to be detected on the top surface of the conveyor belt 4, making the top side of the glass to be detected lean against the rubber pad 13 on the right side of the left side column 12. Utilize the frictional force between the outer surface of the conveyor belt 4 and the left rubber pad 13 and the glass to be detected to simply stop the glass on the outer surface of the conveyor belt 4. Then press the button on the top of the control panel 5 to start the driving block 10, extend the telescopic column 11, causing the sliding plate 7 to move leftward in the inner cavity of the chute 6, that is, driving the cross plate 8 and the right detection column 9 and the right side column 12 on its top to move leftward synchronously. During the movement, as the right side column 12 moves leftward, slowly push the glass to move leftward until it is vertical on the top of the conveyor belt 4. When the right side column 12 cannot move anymore, at this time, the left and right side columns 12 stably place the glass to be detected vertically on the outer surface of the top of the conveyor belt 4. Then press other buttons on the top of the control panel 5 to start all the rollers 3, drive the conveyor belt 4 to rotate. Utilize the frictional force between the conveyor belt 4 and the glass to be detected to be greater than the frictional force between the left and right sides of the glass to be detected and the sides in contact with the left and right rubber pads 13, so that the glass to be detected moves backward as the conveyor belt 4 rotates. When the glass to be detected moves past the left detection column 14 and the right detection column 9, utilize the fact that the bottoms of the left detection column 14 and the right detection column 9 are at the same horizontal plane as the top surface of the conveyor belt 4 to facilitate the simultaneous and complete detection of the left and right sides of the glass to be detected.

[0025] In summary, this glass surface defect detection device, compared with general similar devices, has the advantages of effectively fixing glass to be detected with different thicknesses and driving the glass to move synchronously, facilitating the synchronous detection of both sides of the overall glass.

[0026] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
