Description

Technical Field

[0001] This utility model relates to an automatic detection inkjet printing mechanism for liquid crystal glass, and in particular to an automatic detection inkjet printing mechanism for liquid crystal glass. Background Technology

[0002] During the process of packaging LCD glass into boxes, the LCD glass needs to be transported, inspected, and marked on a conveyor line. Marking can only be performed after the LCD glass has passed the inspection.

[0003] When LCD glass is transported on the conveyor line, it is easy to move and deviate, which makes it impossible for the visual inspection agency to detect all the abnormalities of the LCD glass and to fully inspect whether the LCD glass is qualified.

[0004] In summary, how to achieve automated detection and coding of liquid crystal glass has become an urgent problem for researchers in this field. Utility Model Content

[0005] The technical problem to be solved by this utility model is: how to achieve automated detection and coding of liquid crystal glass;

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] This utility model relates to a liquid crystal glass inspection and coding mechanism, comprising: a conveyor line adapted to transport liquid crystal glass; a visual inspection mechanism slidably disposed above the conveyor line; a coding mechanism slidably disposed above the conveyor line and located behind the visual inspection mechanism; and a alignment mechanism disposed on both sides of the conveyor line. When the liquid crystal glass is transported by the conveyor line to the area below the visual inspection mechanism, the alignment mechanism adjusts the position of the liquid crystal glass for inspection. If the inspection is qualified, the liquid crystal glass continues to be transported by the conveyor line to the area below the coding mechanism for coding. If the inspection is unqualified, the liquid crystal glass does not remain below the coding mechanism for coding.

[0008] In this solution, the conveyor line transports the LCD glass in a linear motion. When the LCD glass is transported to the area below the vision inspection mechanism, the alignment mechanism aligns the LCD glass to facilitate scanning and detection by the vision inspection mechanism. Subsequently, the vision inspection mechanism performs a two-axis linear motion to conduct a comprehensive visual inspection of the LCD glass. Once the LCD glass passes the inspection, it is transported to the area below the inkjet printing mechanism, where the inkjet printing mechanism performs a three-axis motion to print codes on the LCD glass, thus realizing automated inspection and inkjet printing of the LCD glass.

[0009] To illustrate how the visual inspection mechanism achieves two-axis linear motion, this utility model employs a visual inspection mechanism comprising: two first slides arranged in parallel, their length direction parallel to the movement direction of the liquid crystal glass, and located on both sides above the conveyor line; a bracket, both ends of which are connected to the output ends of the first slides and span across the conveyor line; a second slide mounted on the bracket, its length direction perpendicular to the movement direction of the liquid crystal glass; a support frame connected to the output ends of the second slides; and a visual detector fixed to the support frame.

[0010] In this scheme, two first slides work to drive the bracket to move along the liquid crystal glass conveying direction. A second slide is fixed on the bracket, and a support frame is fixed at the output end of the second slide. A vision detector is fixed on the support frame. The vision detector can detect the glass on the conveying line and realize the two-axis movement of the vision detector with the cooperation of the first slide and the second slide.

[0011] In order to illuminate the vision detector, the present invention employs a ring light fixed on the support frame; the vision detector is fixed in the middle of the ring light;

[0012] The ring light illuminates the LCD glass, enabling the visual detector to detect anomalies more efficiently.

[0013] To illustrate the specific structure of the correction mechanism, this utility model adopts the correction mechanism comprising: cylinders fixed on both sides of the conveyor line; and a push plate fixed to the output end of the cylinders and adapted to abut against the side of the liquid crystal glass.

[0014] The cylinders on both sides of the conveyor line work synchronously, driving the two push plates closer together, so that the LCD glass will move towards the middle of the conveyor line, making it easier for the visual inspection mechanism to inspect.

[0015] To illustrate the three-axis motion of the inkjet printing mechanism, this utility model employs an inkjet printing mechanism comprising: a third slide table disposed above one side of the conveyor line; a third slide rail disposed parallel to the third slide table above the other side of the conveyor line; a second bracket, one end of which is fixedly connected to the output end of the third slide table, and the other end of which is slidably connected to the third slide rail; a fourth slide table fixed on the second bracket; a lifting module connected to the output end of the fourth slide table and controlled by the fourth slide table to move perpendicularly to the direction of movement of the liquid crystal glass; and a printhead fixed to the output end of the lifting module and controlled by the lifting module to perform lifting and lowering movements.

[0016] In this solution, one end of the second bracket is slidably connected to the third slide table, and the other end is slidably connected to the third slide rail. When the third slide table is working, it drives the second bracket and the fourth slide table on the second bracket to move along the movement direction of the liquid crystal glass. The lifting module is fixed at the output end of the fourth slide table, realizing movement perpendicular to the direction of the liquid crystal glass. When the lifting module is working, it drives the printhead to move up and down, realizing the three-axis linear motion of the printhead to print codes on the surface of the liquid crystal glass.

[0017] The beneficial effects of this utility model are as follows: This utility model is a liquid crystal glass inspection and coding mechanism. The conveyor line transports the liquid crystal glass in a linear motion. When the liquid crystal glass is transported to the underside of the vision inspection mechanism, the alignment mechanism aligns the liquid crystal glass to facilitate scanning and detection by the vision inspection mechanism. Subsequently, the vision inspection mechanism performs a two-axis linear motion to perform a comprehensive visual inspection of the liquid crystal glass. When the liquid crystal glass passes the inspection, it is transported to the underside of the coding mechanism, where the coding mechanism performs a three-axis motion to print codes on the liquid crystal glass, thus realizing automated inspection and coding of the liquid crystal glass.

Detailed Implementation

[0022] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0023] like Figure 1As shown, this utility model is a liquid crystal glass inspection and coding mechanism, comprising: a conveyor line 1, adapted for transporting liquid crystal glass; a visual inspection mechanism 2, slidably disposed above the conveyor line 1; a coding mechanism 3, slidably disposed above the conveyor line 1 and located behind the visual inspection mechanism 2; and a correction mechanism 4 disposed on both sides of the conveyor line 1. When the liquid crystal glass is transported by the conveyor line 1 to below the visual inspection mechanism 2, the correction mechanism 4 adjusts the position of the liquid crystal glass for inspection. If the inspection is qualified, the liquid crystal glass continues to be transported by the conveyor line 1 to below the coding mechanism 3 for coding. If the inspection is unqualified, the liquid crystal glass will not remain below the coding mechanism 3 for coding.

[0024] In this solution, the conveyor line transports the LCD glass in a linear motion. When the LCD glass is transported to the area below the vision inspection mechanism, the alignment mechanism aligns the LCD glass to facilitate scanning and detection by the vision inspection mechanism. Subsequently, the vision inspection mechanism performs a two-axis linear motion to conduct a comprehensive visual inspection of the LCD glass. Once the LCD glass passes the inspection, it is transported to the area below the inkjet printing mechanism, where the inkjet printing mechanism performs a three-axis motion to print codes on the LCD glass, thus realizing automated inspection and inkjet printing of the LCD glass.

[0025] like Figure 1 As shown, to illustrate how the visual inspection mechanism achieves two-axis linear motion, this utility model employs a visual inspection mechanism 2 comprising: two first slides 21, arranged in parallel with their length direction parallel to the movement direction of the liquid crystal glass, and located on both sides above the conveyor line 1; a bracket 22, with both ends connected to the output ends of the first slides 21, and spanning above the conveyor line 1; a second slide 23, mounted on the bracket 22 with its length direction perpendicular to the movement direction of the liquid crystal glass; a support frame 24, connected to the output ends of the second slides 23; and a visual detector 25, fixed on the support frame 24.

[0026] In this scheme, two first slides work to drive the bracket to move along the liquid crystal glass conveying direction. A second slide is fixed on the bracket, and a support frame is fixed at the output end of the second slide. A vision detector is fixed on the support frame. The vision detector can detect the glass on the conveying line and realize the two-axis movement of the vision detector with the cooperation of the first slide and the second slide.

[0027] like Figure 1 As shown, in order to illuminate the vision detector, the present invention uses a ring light 26 fixed on the support frame 24; the vision detector 25 is fixed in the middle of the ring light 26.

[0028] The ring light illuminates the LCD glass, enabling the visual detector to detect anomalies more efficiently.

[0029] like Figure 1 As shown, in order to illustrate the specific structure of the correction mechanism, the present invention adopts the correction mechanism 4, which includes: cylinders 41 fixed on both sides of the conveyor line 1; and a push plate 42, which is fixed to the output end of the cylinders 41 and adapted to abut against the side of the liquid crystal glass.

[0030] The cylinders on both sides of the conveyor line work synchronously, driving the two push plates closer together, so that the LCD glass will move towards the middle of the conveyor line, making it easier for the visual inspection mechanism to inspect.

[0031] like Figure 2 As shown, to illustrate the three-axis motion of the inkjet printing mechanism, this utility model employs an inkjet printing mechanism 3 comprising: a third slide 31, which is disposed above one side of the conveyor line 1; a third slide rail 32, which is disposed parallel to the third slide 21 above the other side of the conveyor line 1; a second bracket 33, one end of which is fixedly connected to the output end of the third slide 21, and the other end of which is slidably connected to the third slide rail 32; a fourth slide 34, which is fixed on the second bracket 33; a lifting module 35, which is connected to the output end of the fourth slide 34 and is controlled by the fourth slide 34 to move perpendicularly to the direction of movement of the liquid crystal glass; and a printhead 36, which is fixed to the output end of the lifting module 35 and is controlled by the lifting module 35 to perform lifting and lowering movements.

[0032] In this solution, one end of the second bracket is slidably connected to the third slide table, and the other end is slidably connected to the third slide rail. When the third slide table is working, it drives the second bracket and the fourth slide table on the second bracket to move along the movement direction of the liquid crystal glass. The lifting module is fixed at the output end of the fourth slide table, realizing movement perpendicular to the direction of the liquid crystal glass. When the lifting module is working, it drives the printhead to move up and down, realizing the three-axis linear motion of the printhead to print codes on the surface of the liquid crystal glass.

[0033] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model.
