[0002] With the rapid development of electronic information technology, demand for electronic glass, a key component in electronic products such as display panels and touch screens, continues to grow. The production process for electronic glass requires extremely high cleanliness and precision; even the slightest scratch or contamination can render the product scrapped. Therefore, effective protective measures to ensure surface quality during the production, transportation, and storage of electronic glass are crucial.

[0003] Currently, one of the protective measures for electronic glass is to lay release paper between the glasses to prevent damage caused by friction or collision between the glasses, thereby effectively protecting the glass surface. The traditional method of laying paper for electronic glass mainly relies on manual operation, which has many shortcomings. First, manual paper laying is slow and inefficient, and it is difficult to meet the needs of large-scale production. Secondly, manual paper laying cannot ensure the flatness and positioning accuracy of the release paper, which can easily cause the release paper to overlap or misalign, thereby affecting product quality and even causing the product to be scrapped. In addition, manual paper laying also has problems such as high labor intensity, easy fatigue of operators, and safety hazards.

[0004] To overcome the shortcomings of manual paper laying, automated paper laying equipment has emerged in recent years. These devices typically use robotic arms or conveyor belts to automatically transport release paper between glass panels, attempting to improve paper laying efficiency and accuracy.

DETAILED DESCRIPTION

[0023] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0024] like Figures 1 to 5 As shown, the fully automatic off-line paper laying machine for electronic glass described in this embodiment is used to automatically complete the laying of isolation paper between glasses on the electronic glass production line, thereby improving production efficiency and product quality. The paper laying machine is arranged on the glass conveyor line, and its frame 10 serves as the supporting structure of the entire equipment to ensure the stability of the equipment. A paper feeding mechanism 20, a tensioning roller mechanism 30 and a paper laying mechanism are installed on the frame 10. The paper feeding mechanism 20 is used to store and supply isolation paper, for example, it can be in the form of roll paper, and can automatically release the isolation paper as needed; the tensioning roller mechanism 30 is located between the paper feeding mechanism 20 and the paper laying mechanism, and is used to control the tension and conveying speed of the isolation paper, to ensure that the isolation paper enters the paper laying mechanism smoothly, and to avoid problems such as paper wrinkles or breaks.

[0025] The paper laying mechanism is sequentially provided with a first paper feeding mechanism 40, a paper cutting mechanism 50, and a second paper feeding mechanism 60 along the paper laying direction. The paper feeding mechanism 20 is coupled to the first paper feeding mechanism 40 via a tensioning roller mechanism 30. The first paper feeding mechanism 40 delivers the release paper supplied by the paper feeding mechanism 20 to the paper cutting mechanism 50. The delivery speed of the first paper feeding mechanism 40 can be adjusted according to the conveying speed of the glass to ensure that the release paper and the glass move synchronously.

[0026] Specifically, the paper cutting mechanism 50 includes a first bridge body 51, a paper cutter 52, a paper pressing plate 53 and a paper cutting table 54, all of which are arranged along the width direction of the isolation paper. The first bridge body 51 is provided with multiple first cylinders 55 arranged along the width direction of the isolation paper. The output ends of the multiple first cylinders 55 are connected to a knife seat 56, and the paper cutter 52 is detachably mounted on the knife seat 56; there are two paper pressing plates 53, and the two paper pressing plates 53 are mounted on the knife seat 56 through a spring 72 mechanism 70 and are located on both sides of the paper cutter 52; the paper cutting table 54 is arranged opposite to the two paper pressing plates 53, and the paper cutting table 54 is provided with a knife groove 541 adapted to the paper cutter 52; the second paper feeding mechanism 60 is used to deliver the isolation paper cut by the paper cutter 52 to the paper laying station, that is, the second paper feeding mechanism 60 transports the cut paper to the paper laying station to complete the paper laying operation. Its conveying speed can be adjusted according to the glass conveying speed to ensure that the cut paper can be accurately laid between the electronic glasses. The working principle of the retreat mechanism 70 will be described in detail below.

[0027] When the electronic glass is transported to the paper laying station, the paper feeding mechanism 20 releases the isolation paper, the tensioning roller mechanism 30 controls the isolation paper tension and speed, and the isolation paper is fed by the first paper feeding mechanism 40 according to the speed of the glass feeding, so that the isolation paper and the glass move forward synchronously. When the electronic glass reaches the paper laying station, the paper cutting mechanism 50 cuts the isolation paper. At this time, the first bridge body 51 serves as the support structure of the paper cutting mechanism 50, and multiple first cylinders 55 are started synchronously, driving the knife seat 56 to move downward, driving the paper cutter 52 to cut, the paper pressing plate 53 presses the isolation paper against the paper cutting table 54, and the knife groove 541 guides the paper cutter 52 to cut, ensuring cutting accuracy. Then the second paper feeding mechanism 60 continues to transport the cut paper forward to ensure that it is laid on the electronic glass. In this way, through the above structural design, the paper size after cutting is uniform, the quality is stable, and the repeatability is good.

[0028] In some embodiments, as Figure 2 、 Figure 5 and Figure 6 In this embodiment, the two paper pressing plates 53 are arranged one high and one low, and the paper cutting table 54 has a high and low table 542 adapted to the two paper pressing plates 53, and the high and low table 542 is located on both sides of the notch of the knife groove 541.

[0029] In this way, the two cardboard pressing plates 53 are designed with one high and one low, and are combined with the corresponding high and low surfaces 542 on the paper cutting table 54, so that the release paper is tilted when it is pressed, rather than horizontal. This tilted design complements the cutting method of the serrated blade (paper cutter 52), which can significantly improve cutting efficiency and quality. Specifically, when the release paper is fed into the paper cutting mechanism 50 and pressed by the cardboard pressing plate 53, due to the height difference between the cardboard pressing plate 53 and the table 542, the release paper will form an inclined angle. At this time, when the serrated blade moves downward to cut, its serrated blade will more easily cut into the release paper in sequence, forming multiple small incisions. That is, due to the existence of the inclined angle, the contact area of ​​each sawtooth with the release paper is larger, and the pressure applied is more concentrated, making it easier to overcome the resistance of the release paper and allowing the blade to cut smoothly. This cutting method not only improves cutting efficiency, but also effectively reduces the tearing and burring of the release paper, thereby further improving the cutting quality.

[0030] In some embodiments, as Figure 6 As shown, a silicone pad 531 is provided on the side of the two paper pressing plates 53 facing the paper cutting table 54. The silicone pad 531 has a high friction coefficient and can enhance the friction between the paper pressing plates 53 and the release paper. That is, when the paper pressing plates 53 press the release paper, the silicone pad 531 can effectively prevent the release paper from sliding or deflecting during the cutting process, thereby improving cutting accuracy and stability.

[0031] In some embodiments, as Figure 2 、 Figure 5 As shown, the retreat mechanism 70 includes a U-shaped connecting seat 71, a spring 72 and a guide rod 73. The two pressure paper boards 53 are fixedly connected to the two ends of the U-shaped connecting seat 71, and a guide seat 74 is provided on the top of the U-shaped connecting seat 71; the guide rod 73 is slidably arranged in the guide seat 74, and the bottom end of the guide rod 73 passes through the guide seat 74 and is fixedly connected to the knife seat 56; the spring 72 is passed through the guide rod 73, and one end of the spring 72 is fixed to the top end of the guide rod 73, and the other end abuts against the guide seat 74.

[0032] When the cutter 52 is in the working state, the two pressing plates 53 are in the initial position under the action of the spring 72 of the spring mechanism 70. At this time, the pressing plates 53 will cover the blade of the cutter 52 to avoid possible damage caused by the exposed blade. When the cutter 52 needs to be pressed down for cutting, the cutter 52 will first contact the pressing plate 53 and move downward against the elastic force of the spring 72. At this time, the pressing plate 53 will move downward with the cutter 52 until the pressing plate 53 contacts the cutting table 54. The spring 72 is compressed and stores a certain amount of elastic potential energy. Then the cutter 52 continues to press down until it enters the knife groove 541 to complete the cutting of the release paper. When the cutting is completed, the cutter 52 returns to its original position, the elastic potential energy of the spring 72 is released, and the pressing plate 53 is pushed upward to cover the blade of the cutter 52 again, returning to its initial state, thereby ensuring the safety of the operator.

[0033] In some embodiments, as Figure 5 As shown, the first paper feed mechanism 40 includes a servo motor, an upper roller 42, and a driven lower roller 43. Both the lower roller 43 and the upper roller 42 are arranged along the width of the release paper and spaced apart to form a paper feed path. The servo motor offers advantages such as fast response and high control accuracy. Working in conjunction with the upper roller 42 and the lower roller 43, it ensures the stability and reliability of the paper feed mechanism.

[0034] In some embodiments, as Figure 5 As shown, vertically arranged guide rails 44 and sliders 45 slidably connected to the guide rails 44 are provided at both axial ends of the upper roller 42, and the ends of the upper roller 42 are rotatably mounted on the sliders 45; the frame 10 is fixedly mounted with a second cylinder 46, the second cylinder 46 is vertically arranged, and the power output end of the second cylinder 46 is hinged to the slider 45.

[0035] Through this structural design, the second cylinder 46 can control the up and down movement of the slider 45, thereby controlling the lifting and lowering of the upper roller 42. For example, when the release paper needs to be replaced or equipment maintenance needs to be performed, the upper roller 42 can be lifted by controlling the extension and retraction of the second cylinder 46, making it easier for the operator to perform related operations. In addition, the power output end of the second cylinder 46 is hingedly connected to the slider 45, giving the upper roller 42 a certain degree of freedom. This means that the upper roller 42 can float slightly up and down in the vertical direction. In actual operation, the upper roller 42 will exert a certain amount of pressure on the release paper in the paper feed channel under the action of its own gravity. This pressure can enhance the friction between the release paper and the lower roller 43, improve the stability and reliability of paper feeding, and ensure that the release paper remains flat during the paper feeding process, avoiding problems such as slipping or wrinkling.

[0036] In some embodiments, as Figure 2 、 Figure 3 and Figure 5 As shown, the slider 45 is provided with a second bridge 80 extending along the width of the release paper. A pressure block 81 is hingedly connected to the second bridge 80. A plurality of rollers 82 are rotatably mounted on one side of the pressure block 81, which contact the upper roller 42. A compression spring 83 is fixedly mounted on the opposite side. The end of the compression spring 83 facing away from the pressure block 81 is connected to the second bridge 80. In practice, the compression spring 83 constantly applies downward pressure to the pressure block 81, which is transmitted to the upper roller 42 via the rollers 82. This increases the pressure of the upper roller 42 on the release paper, thereby improving the friction between the release paper and the upper and lower rollers, making the release paper more stable during paper feeding and less prone to slipping or deviation, thereby improving the stability and reliability of paper feeding.

[0037] In some embodiments, as Figures 2 to 5 As shown, the second paper feeding mechanism 60 includes a guide plate 61 arranged obliquely downward, a plurality of belts 62 arranged at intervals along the width direction of the release paper, and a transmission shaft 63 for synchronously driving each belt 62 to rotate synchronously. The edge of the guide plate 61 extends toward the paper cutting table 54 to form an arc plate 64 that is matched with the surface of the paper cutting table 54, and an opening is opened on the guide plate 61 to expose the belt 62. The servo motor is connected to the transmission shaft 63 through a transmission mechanism, and the belt surface of the belt 62 is flush with the plate surface of the guide plate 61.

[0038] With this structural design, the edge of the guide plate 61 extends to form an arc plate 64, which is smoothly matched with the surface of the paper cutting table 54, ensuring a smooth transition of the release paper from the paper cutting mechanism 50 to the second paper feeding mechanism 60, effectively preventing the release paper from bending or wrinkling during the transition process, and ensuring the flatness of the release paper; and multiple belts 62 are evenly distributed on the guide plate 61, and openings corresponding to the belts 62 are opened on the guide plate 61 so that the belts 62 can fully contact the release paper. When the release paper is output from the paper cutting mechanism 50, it will fall on the arc plate 64 of the guide plate 61, and then move downward along the guide plate 61, and be evenly supported and clamped by multiple belts 62, thereby achieving smooth and reliable transportation.

[0039] This fully automatic offline paper laying machine for electronic glass features fast cutting speed and high efficiency. It precisely controls the size and position of the release paper, ensuring its flatness and positional accuracy. The cut release paper is uniform in size, stable in quality, and highly repeatable. Furthermore, automated operation reduces manual intervention, labor intensity, and the likelihood of safety incidents, effectively meeting the needs of large-scale production.
