Description

Technical Field

[0001] This application relates to the field of testing equipment technology, and specifically discloses a glass cutting edge crack damage testing device. Background Technology

[0002] Glass panels are cut to size during production, and microcracks can easily form on the cut edges during this process. These microcracks significantly weaken the overall strength of the glass panel, thus greatly affecting its performance. Therefore, timely and effective inspection is necessary to determine the extent of damage. Currently, defect inspection of glass panels is mainly done manually on-site, which consumes a lot of manpower and resources and is inefficient. In addition, microcracks are less than 0.1mm wide and cannot be directly observed with the naked eye, making it easy to miss them.

[0003] To address the aforementioned issues, this application discloses a glass cutting edge crack damage detection device. Utility Model Content

The linear guide rail and the first servo screw module are arranged side by side on the detection platform along the second direction. The transport platform is slidably arranged on the linear guide rail and connected to the first servo screw module.

[0007] More preferably, the dual-axis rotary drive unit includes a gearbox and a servo motor. Inside the gearbox, two first gears are rotatably arranged. Inside each of the two first gears, a main shaft passes through the transport platform and connects to the rotating platform. Inside the gearbox, two rotatable worms mesh with the two first gears respectively. The two worms extend to the outside of one side of the gearbox and are respectively equipped with second gears driven by a gear transmission belt. The servo motor is located on the other side of the gearbox and is connected to one of the worms.

[0008] More preferably, the vacuum suction cup has a square structure, and the length and width of the vacuum suction cup are smaller than the length and width of the glass to be tested.

The above method frees up manpower and improves work efficiency.

[0014] 2. This application ensures that operators can accurately place the two pieces of glass on the two adsorption and fixing mechanisms by placing the positioning unit on the testing platform, thereby facilitating accurate testing in the later stage.

[0018] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0019] In the description of this application, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the component or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Example

[0020] To address the shortcomings of existing technologies that primarily rely on manual, offline inspection for defect detection in glass panels (mainly rectangular glass panels), which consumes significant manpower and resources and is inefficient, this paper refers to... Figures 1-3 As shown, this application discloses a glass cutting edge crack damage detection device, including a detection platform 10, a glass transport mechanism 20, a dual-station rotating mechanism 30, a dual-station detection mechanism 40, and two adsorption and fixing mechanisms 50. The glass transport mechanism 20 includes a transport platform 21 arranged above the inspection platform 10 along a first direction. Above the inspection platform 10 is a moving drive unit 22 connected to the transport platform 21 for driving it to move along the first direction. The moving drive unit 22 includes a linear guide rail 221 and a first servo screw module 222. The linear guide rail 221 and the first servo screw module 222 are arranged side by side on the inspection platform 10 along a second direction. The transport platform 21 is slidably mounted on the linear guide rail 221 and connected to the first servo screw module 222. When the operator places two glass panels on the two adsorption and fixing mechanisms 50 at the loading and unloading position, the first servo screw module 222 will cooperate with the linear guide rail 221 to drive the transport platform 21 to the inspection position. Otherwise, the process will not be described in detail.

[0021] The dual-station rotating mechanism 30 includes two rotating platforms 31 arranged side by side above the transport platform 21 along the second direction. A dual-axis rotating drive unit 32 is provided below the detection platform 10, connecting its two rotating parts to the two rotating platforms 31 respectively. Two adsorption and fixing mechanisms 50 are respectively arranged on the two rotating platforms 31, and each of the two adsorption and fixing mechanisms 50 includes a vacuum suction cup 51. Preferably, the vacuum suction cup 51 has a square structure, and the length and width of the vacuum suction cup 51 are smaller than the length and width of the glass to be tested. The dual-axis rotary drive unit 32 includes a gearbox 321 and a servo motor 322. Inside the gearbox 321, two first gears 323 are rotatably arranged. Each of the two first gears 323 has a main shaft 324 that passes through the transport platform 21 and connects to the rotary platform 31. Inside the gearbox 321, two rotatable worm gears 325 mesh with the two first gears 323 respectively. The two worm gears 325 extend to one side of the gearbox 321 and are each equipped with a second gear 327 that is driven by a gear transmission belt 326. The servo motor 322 is located on the other side of the gearbox 321 and connects with one of the worm gears 325. When fixing the two glass panels, the operator places the two glass panels to be inspected on two vacuum suction cups 51, and ensures that the four cut edges of the two glass panels protrude from the vacuum suction cups 51. During the inspection process, if the crack damage inspection of one cut edge of the two glass panels is completed, the servo motor 322 drives a worm gear 325 to rotate and, through the transmission of two second gears 327, causes another worm gear 325 to rotate. In this way, the two first gears 323 start to drive the two drive shafts to rotate together, causing the two rotating platforms 31 to rotate, thereby facilitating the subsequent crack damage inspection of the next cut edge. The dual-station inspection mechanism 40 includes a frame 41 located near the end of the conveying platform 21 and above the inspection platform 10 along the second direction; a bidirectional moving drive unit 42 located along the second direction on the side of the frame 41 facing the conveying platform 21; two lifting drive units 43 connected to the two drive parts of the bidirectional moving drive unit 42; and two inspection units 44 connected to the lifting parts of the two lifting drive units 43. The bidirectional moving drive unit is preferably a bidirectional lead screw module, the lifting drive unit 43 is a second servo lead screw module, and the inspection unit 44 is preferably a microscopic imager.

[0022] When performing crack and breakage detection on the cut edge of two glass panels, two lifting drive units 43 drive two detection units 44 to descend to a set position. After that, the bidirectional movement drive unit 42 drives the two lifting drive units 43 to move along the second direction on the cut edge of the two glass panels until the two detection units 44 complete the crack and breakage detection on the cut edge. It should also be noted that in this application, any glass panel with cracks or damage at the cut edge is considered a defective product, while the rest is considered a qualified product.

[0023] Furthermore, the testing equipment of this application shall be equipped with a touch screen display (not shown in this application), so that operators can easily understand the relevant testing information in a timely manner and thus know whether the glass panel is a qualified product.

[0024] In addition to the above, this application also provides a placement and positioning unit 60 at the loading and unloading position of the testing platform 10. The placement and positioning unit 60 includes a U-shaped frame 61 horizontally set at the loading and unloading position of the testing platform 10. The two vertical parts of the U-shaped frame 61 are respectively provided with first positioning blocks 62 for restricting the movement of the transport platform 21, and the horizontal part of the U-shaped frame 61 is provided with second positioning blocks 63 for positioning the glass. In the loading and unloading state, the transport platform 21 of this application will be blocked by the two first positioning blocks 62. That is to say, there must be a distance between the transport platform 21 and the second positioning block 63. This can ensure that the glass panel is exposed to the adsorption and fixing mechanism 50 and can ensure the positioning and placement of the glass panel.
