Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal substrate glass production, in particular to a multi-edge detection device for liquid crystal substrate glass. Background Technique

[0002] The semi-finished product processing process is an important part of the production of liquid crystal glass substrates. The semi-finished product processing process is mainly used for a series of processes such as horizontal segmented cutting, Robot feeding, weighing, vertical cutting, cooling, thickness measurement, automatic detection, manual sampling inspection, sorting, and blanking after the glass flows out of the muffle furnace. The task of the process is to convey, weigh, longitudinally cut, sort, pack, and feed the formed and horizontally cut glass plates to the grinding process. Among them, the integrity of the glass after longitudinal cutting is particularly important. Once the longitudinal cutting quality is poor and the integrity of the glass itself is poor, it will have a great impact on subsequent processes such as packing or flowing into the grinding process.

[0003] At present, in the glass substrate production line, a inspection machine is used to judge glass defects. Due to the particularity of the inspection machine, it can accurately detect glass missing blocks, but its ability to detect multi-edges of glass is greatly insufficient. When the multi-edges of the glass are not detected in time and flow into the subsequent processes, whether it is packing or directly flowing into the grinding process, it will have a great impact, resulting in production interruption and seriously affecting the operation rate. Therefore, we propose a multi-edge detection device for liquid crystal substrate glass. Content of the Utility Model

[0005] To achieve the above purposes, the utility model is realized through the following technical solutions: A multi-edge detection device for liquid crystal substrate glass, including a glass conveying track and a plurality of transport trolleys arranged on the upper part of the glass conveying track. A plurality of transport trolleys can all move on the glass conveying track. The driving end of each transport trolley carries a liquid crystal substrate glass. A gantry is connected in a section of the glass conveying track. Servo drive modules are installed on both sides of the gantry. A slide cylinder is installed at the driving end of the servo drive module. A photoelectric sensor is installed at the driving end of the slide cylinder. The servo drive module can drive the photoelectric sensor to reciprocate along the edge of the liquid crystal substrate glass. During the movement, the photoelectric sensor detects the liquid crystal substrate glass.

[0006] Further, a clamping jaw is installed at the driving end of the transport trolley. The clamping jaw is set as a suction cup structure. Through the negative pressure adsorption of a plurality of suction cups on the liquid crystal substrate glass, the transport trolley can carry the liquid crystal substrate glass and move along the glass conveying track.

[0007] Further, a support arm is installed at the driving end of the sliding table cylinder. The support arm is arranged in a "Z" shape, and the end of the support arm is connected with a mounting seat which is arranged in a "U" shape.

Detailed implementation mode

[0021] 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 work shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-5 , the present invention provides a technical solution: a multi-sided detection device for liquid crystal substrate glass, including a glass conveying track 1. The glass conveying track 1 is a circulating conveying structure. At regular intervals on the glass conveying track 1, a transport trolley 2 is provided. That is to say, the transport trolley 2 can move cyclically along the glass conveying track 1. A jaw 3 structure composed of a plurality of suction cups is equipped at the driving end of each transport trolley 2. Through this jaw 3, the transport trolley 2 can carry a liquid crystal substrate glass 11. That is to say, the transport trolley 2 can carry a liquid crystal substrate glass 11 and move along the glass conveying track 1;

[0023] In the section along the glass conveying track 1, a gantry 4 is provided. A sensor (i.e., a position sensor) capable of sensing the arrival of the transport trolley 2 is provided on the gantry 4. When the transport trolley 2 carrying the liquid crystal substrate glass 11 comes to the position of the gantry 4, it will be detected by the position sensor. At this time, the transport trolley 2 stops moving. Servo drive modules 5 are installed on both sides of the gantry 4. The servo drive module 5 is actually a structure in which a servo motor drives a ball screw to rotate to achieve driving. A sliding table cylinder 6 is installed at the driving end of the servo drive module 5. A "Z"-shaped support arm 7 is installed at the telescopic end of the sliding table cylinder 6. The end of the support arm 7 is connected to a "U"-shaped mounting seat 8. A photoelectric sensor 9 is installed inside the mounting seat 8. Among them, the photoelectric sensor 9 is composed of a transmitting end 91 and a receiving end 92. The transmitting end 91 and the receiving end 92 are symmetrically installed on the inner side of the mounting seat 8. For a qualified liquid crystal substrate glass 11, its edge will not block the transmitting end 91 and the receiving end 92. On the contrary, for a liquid crystal substrate glass 11 with multi-sided problems, it will block the transmitting end 91 and the receiving end 92. When the liquid crystal substrate glass 11 is in place, the sliding table cylinder 6 pushes the overall movement of the support arm 7, the mounting seat 8, the transmitting end 91 and the receiving end 92, so that the transmitting end 91 and the receiving end 92 are located on both sides of the edge of the liquid crystal substrate glass 11. The servo drive module 5 drives the overall movement of the sliding table cylinder 6, the support arm 7, the mounting seat 8, the transmitting end 91 and the receiving end 92 from top to bottom. During the movement, the photoelectric sensor 9 detects the liquid crystal substrate glass 11.

[0024] Please refer to Figure 6, the detection device is also equipped with a background terminal 10. The background terminal 10 can communicate with the photoelectric sensor 9. The background terminal 10 is built-in with an alarm module 101. The background terminal 10 can control the alarm module 101 to issue an alarm. When the photoelectric sensor 9 detects the liquid crystal substrate glass 11 with a multi-sided problem, it will immediately feedback to the background terminal 10. The background terminal 10 controls the alarm module 101 to issue an alarm, and the transport cart 2 will transport the liquid crystal substrate glass 11 with the multi-sided problem to the waste area.
