Description

Technical Field

[0001] The utility model relates to the detection field, in particular to a glass edge breakage detection device. Background Art

[0002] Glass screen printing refers to the use of screen printing plates and glass glazes to perform decorative printing on glass products. The glass screen printing process requires the use of a glass screen printer as described in the announcement number "CN218287085U" to print on the glass, and completes the processes of stretching the screen, sizing, drying, exposure, developing, drying flat glass, cutting, grinding, cleaning and drying, printing, sintering, etc.

[0003] As glass is fragile, it is necessary to ensure that the edges of the glass are not broken before printing. If broken, the screen will be damaged during the printing process, and ink will be wasted, affecting production. At present, in order to prevent the glass from breaking before printing, it is often necessary to add an inspection station to observe the edge of the glass through manual visual inspection and screen out broken glass in time. However, this visual inspection method has errors in naked eye detection and is inefficient, so it needs to be solved urgently. Summary of the invention

[0004] In order to avoid and overcome the technical problems existing in the prior art, the utility model provides a glass edge breakage detection device. The utility model realizes automatic detection of glass edge breakage, and has high detection efficiency and accuracy.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A glass edge breakage detection device comprises a detection platform and an X-axis slide rail suspended above the detection platform surface through a mounting frame, the glass to be detected is fixed on the positioning platform and the positioning platform and the X-axis slide rail are slidably matched, the edge of the glass to be detected is arranged parallel to the X-axis slide rail; at least one group of detection optical fibers is also fixed between the X-axis slide rail and the detection platform surface, and the detection optical fibers and the edge of the glass to be detected are located in the same vertical plane.

[0007] As a further solution of the utility model: two groups of detection frames are symmetrically arranged below the bracket of the X-axis slide rail, and detection optical fibers are arranged on the two detection frames to correspond to the positions of the two side edges of the glass.

[0008] As a further solution of the utility model: a Z-axis slide rail is provided on the detection frame along the vertical direction, and the detection frame slides and cooperates with the bracket of the X-axis slide rail along the vertical direction through the Z-axis slide rail, and the moving path of the detection frame and the moving path of the positioning platform avoid each other in the vertical direction.

[0009] As a further solution of the utility model: the detection frame is horizontally provided with a Y-axis slide rail arranged perpendicularly to the X-axis slide rail, and the detection optical fiber is fixed after sliding along the Y-axis slide rail; the detection frame is also provided with a scale arranged along the length direction of the Y-axis slide rail.

[0010] As a further solution of the utility model: two sets of supporting frames parallel to each other are arranged on the positioning platform along the direction perpendicular to the X-axis slide rail, and conveying belts for conveying glass are arranged on the two supporting frames along the length direction, and the conveying belts are driven to rotate by the driving wheel.

[0011] As a further solution of the utility model: along the conveying direction of the conveyor belt, an adsorption platform which can be raised and lowered in the vertical direction is arranged at the rear end of the support frame, and the adsorption platform abuts against the glass surface after rising in the vertical direction; an adsorption hole connected with the vacuum adsorption equipment is opened on the surface of the adsorption platform.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model suspends the X-axis slide rail on the surface of the detection table so that when the X-axis slide rail transports the glass to be detected, the detection optical fiber can be located below the glass. By aligning the detection optical fiber with the edge of the glass to be detected and calculating the passing time of the detection optical fiber sensing, it can be determined whether the edge of the transported glass is chipped or broken, thereby realizing automatic detection of broken glass edges with high detection efficiency and accuracy.

[0014] 2. The detection frame of the utility model can freely adjust the detection height of the detection optical fiber through the sliding cooperation of the bracket of the Z-axis slide rail and the X-axis slide rail. The arrangement of the Y-axis slide rail can adjust the horizontal distance between the detection optical fiber and the edge of the glass. With the cooperation of each other, the position of the detection optical fiber can be freely adjusted to adapt to the detection of glass of different sizes.

[0015] 3. The utility model receives and conveys the glass through the conveyor belt on the positioning table. When the glass is delivered to the right place, the glass is vacuum adsorbed and positioned through the adsorption table to ensure that the glass remains stable during the conveying process and the accuracy of the detection results is ensured.

[0023] 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

[0024] Please refer to Figures 1 - 2 , in the embodiments of the present invention, a glass edge breakage detection device includes a detection table 1 and an X-axis slide rail 2 suspended above the tabletop of the detection table 1 through a mounting frame 11. The X-axis slide rail 2 is an electric slide rail for driving the positioning table 3 to slide, and the positioning table 3 is used to position the glass to be detected

[0025] The positioning table 3 includes two groups of parallel supporting brackets. The supporting brackets and the X-axis slide rail 2 are arranged perpendicular to each other for receiving and conveying the glass to be detected. The conveying unit on the supporting bracket is preferably a conveyor belt 32. The conveyor belt 32 is driven by a driving wheel 31 to rotate. After the glass is conveyed to the supporting bracket by the production line, it is conveyed along the direction perpendicular to the X-axis slide rail 2 on the conveyor belt 32 to the end of the supporting bracket. An adsorption table 33 may be provided at the end of the supporting bracket. The adsorption table 33 is driven by a linear power source such as a cylinder or a linear screw rod, so as to generate a lifting action in the vertical direction. When the glass is conveyed to the position along the supporting bracket, the adsorption table 33 rises and abuts against the lower surface of the glass. Adsorption holes 331 are formed on the adsorption table 33. The adsorption holes 331 can be connected to suction components such as a vacuum suction pump to adsorb the glass by vacuum suction to prevent the glass from shaking. After the detection is completed, the driving wheel 31 rotates in reverse to send the glass along the X-axis slide rail 2 direction to the next production station; for example, it can enter the next station, rotate 90 degrees and then be conveyed back to the detection device to detect the upper and lower sides of the glass

[0026] Two groups of detection frames 4 are symmetrically arranged below the bracket of the X-axis slide rail 2. A Y-axis slide rail 44 perpendicular to the X-axis slide rail 2 is horizontally opened on the detection frame 4. The detection optical fiber 43 slides along the Y-axis slide rail 44 and is fixed, so as to adjust the horizontal distance between the detection optical fiber 43 and the edge of the glass to be detected. A scale 42 arranged along the length direction of the Y-axis slide rail 44 is also provided on the detection frame 4 to judge the adjustment distance of the detection optical fiber 43

[0027] A Z-axis slide rail 41 is provided on the detection frame 4 in the vertical direction. The detection frame 4 is fixed after slidingly mating with the bracket of the X-axis slide rail 2 in the vertical direction through the Z-axis slide rail 41, so as to adjust the height of the detection optical fiber 43.

[0028] When the positioning table 3 fixes the glass and slides along the X-axis slide rail 2, the two side edges of the glass pass through the detection optical fiber 43, and the times t1 and t2 sensed by the two detection optical fibers 43 are recorded. t1 × shuttle speed = the left side length of the glass, and t2 × shuttle speed = the right side length of the glass. By comparing the lengths of the left and right sides or the values of t1 and t2, it can be determined whether the edge of the conveyed glass is missing a corner or broken, so as to determine whether the glass is broken.
