[0023] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] See also Figure 1 and Figure 2 The present invention provides a glass printing positioning device, comprising: a sheet material guide component 1 and a clapper positioning component 2, wherein the sheet material guide component 1 is transversely mounted on the feed end of a conveyor belt 4, and the clapper positioning component 2 is transversely mounted on the conveyor belt 4 and is located behind the sheet material guide component 1.

[0025] The sheet guide assembly 1 includes: a mounting seat 11, a guide rod 12, a screw rod 13, a hand wheel 14, a position indicator 15, a guide device 16, a screw nut 161, a guide wheel 162, and a tightening handle 163. The mounting seat 11 is symmetrically arranged on the left and right sides of the conveyor belt 4, and the two guide rods 12 are laterally supported above the conveyor belt 4. The screw rods 13 are respectively arranged on the two mounting seats 11 on the left and right sides. The screw rods 13 are parallel to the two guide rods 12 and are located in the middle of the two guide rods 12. The hand wheel 14 is arranged on the screw rod 13 and is located outside the mounting seat 11. The position indicator 15 is connected to the hand wheel 14. The guide device 16 is provided on the screw rod 13 and the guide rod 12 and is located on the inner side of the mounting seat 11. The screw nut 161 is sleeved on the screw rod 13 and connected to the guide device 16. The guide device 16 guides the glass sheet material. A row of guide wheels 162 are provided at the bottom of the guide device 16 to guide the glass sheet material. The tightening handle 163 is provided on the guide device 16, and the guide device 16 is fixed to the guide rod 12 by the tightening handle 163. Loosening the tightening handle 163 on the guide device 16 and turning the hand wheel 14 will cause the guide device 16 to move along the guide rod 12. The position value of the guide device 16 is displayed by the position display 15, so as to conveniently and accurately move the distance of the guide device 16 to meet the requirements of glass sheets of different specifications and sizes.

[0026] In the middle of the guiding rod 12, there are also two sets of shunting devices 17 arranged side by side. Each set of the shunting device 17 includes: a shunting block movably sleeved on the guiding rod 12, and a spacer 171 arranged on the shunting block. The shunting block is fixed on the guiding rod 12 through a set screw handle 163. Loosen the set screw handle 163 on the shunting device 17, and the shunting device 17 can be moved along the guiding rod 12 to an appropriate distance to adapt to glass plate materials of different specifications. The bottom of the shunting device 17 is provided with a spacer 171. When two glass plate materials need to be produced simultaneously, the two spacers 171 cooperate with the guiding devices 16 on the left and right sides to respectively conduct conveying and guiding for the two glass plate materials, realizing the shunting of the two glass plate materials. When only a single glass plate material is produced, the two spacers 171 need to be removed, and the guiding devices 16 on the left and right sides conduct conveying and guiding for the single glass plate material.

[0027] The platen positioning assembly 2 includes: a stop rod 21, rubber columns 22, a cylinder 23, a profile mounting seat 24, a profile 25, a reflection optical fiber seat 26, a first reflection optical fiber 27, a second reflection optical fiber 28, and an opposed optical fiber 29. The stop rod 21 and the profile 25 are horizontally arranged above the conveyor belt 4 one above the other. The stop rod 21 is fixed on the equipment through the cylinders 23 on the left and right sides. The cylinders 23 drive the stop rod 21 to move up and down. Under the action of the cylinders 23, the stop rod 21 descends to block the glass panel conveyed forward for platen positioning (straightening the skewed plate material and aligning the two plate materials). A number of rubber columns 22 are inlaid on the stop rod 21, and the rubber columns 22 block and straighten the glass plate material conveyed forward. The profile 25 is arranged above the stop rod 21, and the profile 25 is fixed on the equipment through the profile mounting seats 24 on the left and right sides. Two sets of reflection optical fiber seats 26 are arranged on the profile 25, and the two sets of reflection optical fiber seats 26 respectively correspond to the left and right two glass plate materials below. A first reflection optical fiber 27 and a second reflection optical fiber 28 are installed on each reflection optical fiber seat 26. The first reflection optical fiber 27 is arranged in front of the profile 25, and the second reflection optical fiber 28 is arranged behind the profile 25. The detection position of the first reflection optical fiber 27 is the position where the glass plate material is straightened, which is used to detect whether the glass plate material is straightened and feed back the induction information to the control system of the equipment. Then, the cylinder 23 drives the stop rod 21 to retract upward, and the aligned glass plate material runs to the printing station for pattern spraying. The second reflection optical fiber 28 detects whether the glass plate material that has completed alignment has completely exited the stop rod 21, preventing the lifted stop rod 21 from accidentally operating and descending for platen action, thereby pressing the glass plate material that has not completely exited the stop rod 21 and causing an abnormality. The opposed optical fibers 29 are installed in pairs on both sides of the conveyor belt 4 and in front of the stop rod 21. The opposed optical fibers 29 are used to sense the glass plate material. When the opposed optical fibers 29 sense the glass plate material conveyed forward, they feed back the signal to the control system of the equipment, and the control system then issues an instruction to drive the cylinder 23 to drive the stop rod 21 to descend to the platen height.

[0028] The working principle of the present invention is as follows:

[0029] 1. Double-sheet blank positioning:

[0030] Please refer to Figure 1 , where two glass sheets are fed side by side into the conveyor belt 4 manually or by the upstream automatic line. The conveyor belt drives the sheets into the sheet guiding assembly 1, and the sheet guiding assembly 1 guides and diverts, and roughly positions the two glass sheets (glass sheet one 31 and glass sheet two 32). The two glass sheets will continue to move forward and be sensed by the opposed fiber optic 29. At the same time as the sensing, a descending signal is sent to the cylinder 23. The glass sheets continue to move forward until they are blocked by the front stop bar 21. The first-arriving glass sheet slides and rubs on the conveyor belt 4. When the latter glass sheet touches the stop bar 21 and is aligned, the two reflection fibers one 27 on the left and right sides are triggered simultaneously, and the cylinder 23 drives the stop bar 21 to rise. The two glass sheets move forward simultaneously to the printing station of the equipment for pattern spraying. The two reflection fibers two 28 detect whether the glass sheets that have completed the board alignment have completely exited the board stop bar 21, so as to avoid being damaged due to abnormal in-and-out board signals of the glass sheets transported in a front-back flow manner.

[0031] 2. Single-sheet blank positioning:

[0032] Please refer to Figure 2 , remove the two spacers 171, and a single glass sheet 33 is fed into the conveyor belt 4 manually or by the upstream automatic line. The conveyor belt drives the sheet into the sheet guiding assembly 1, and the guiding devices 16 on the left and right sides of the sheet guiding assembly 1 convey, guide, and roughly position the single glass sheet 33. The single glass sheet 33 will continue to move forward and be sensed by the opposed fiber optic 29. At the same time as the sensing, a descending signal is sent to the cylinder 23. The glass sheet continues to move forward until it is blocked by the front stop bar 21. The single glass sheet 33 slides and rubs on the conveyor belt 4 and is aligned. The two reflection fibers one 27 on the left and right sides are triggered simultaneously, and the stop bar 21 rises. The single glass sheet 33 moves forward to the printing station of the equipment for pattern spraying; the two reflection fibers two 28 detect whether the glass sheets that have completed the board alignment have completely exited the board stop bar 21, so as to avoid being damaged due to abnormal in-and-out board signals of the glass sheets transported in a front-back flow manner.

[0033] In summary, the present invention has the following beneficial effects:

[0034] 1. In the front section, the sheet guiding assembly conveys, guides, and roughly positions the glass sheets, and in the rear section, the board alignment assembly performs board alignment and fine positioning, which can effectively improve the spraying quality of the pattern;

[0035] 2. It can flexibly be compatible with the production of glass panels of different specifications and sizes;

[0036] 3. It can flexibly be compatible with the production modes of single-piece glass sheet materials and double-piece glass sheet materials;

[0037] 4. The platen positioning component adopts dual fiber optic signal detection to ensure smooth positioning and protect the sheet material from being damaged by pressure.

[0038] The above are only the preferred embodiments of the present invention and are 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.
