Description

Technical Field

[0001] The invention belongs to the field of conveying technology, and specifically relates to conveying thin materials, and in particular to a glass substrate packaging paper conveying mechanism and a conveying process. Background Art

[0002] Glass substrates, especially glass substrates for computers and tablets, are usually wrapped with pearl paper, which has a very smooth surface.

[0003] In the related art, a driving roller is usually arranged on the workbench, and the driving roller rotates circumferentially to drive the packaging paper to move horizontally on the workbench; however, if the distance between the driving roller and the workbench is too small, a large squeezing force will be applied to the packaging paper, which may easily cause the paper to deform or break; and if the distance between the driving roller and the workbench is too large, the driving roller will idle, and thus the packaging paper cannot be driven to be transported normally. Therefore, it is necessary to adjust the distance between the driving roller and the workbench according to the thickness of the packaging paper to facilitate the transportation of the packaging paper.

[0004] Therefore, due to the changes in humidity and temperature in the working environment, the increase in humidity will cause the paper to become larger, thereby reducing the friction, resulting in a decrease in the friction between the packaging paper and the drive roller, thereby causing the drive roller to idle relative to the packaging paper, which is a technical problem that urgently needs to be solved in this field.

[0005] It should be noted that the above information disclosed in this background technology section is only used to understand the background technology of the present application concept, and therefore, the above description is not considered to constitute information of the prior art.

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

[0029] The research found that the shortcomings of the prior art are as follows: In the related art, the packaging paper is driven to move by setting a driving roller on the upper surface of the packaging paper. However, if the distance between the driving roller and the workbench is too small, a large squeezing force will be applied to the packaging paper, which may easily cause the paper to deform or break; and if the distance between the driving roller and the workbench is too large, the driving roller will idle, and thus the packaging paper cannot be driven to be transported normally. Therefore, it is necessary to adjust the distance between the driving roller and the workbench according to the thickness of the packaging paper to facilitate the transportation of the packaging paper.

[0030] However, due to changes in humidity and temperature in the working environment, the friction between the packaging paper and the driving roller will decrease, resulting in the driving roller idling relative to the packaging paper.

[0031] Therefore, how to solve the problem of idling of the driving roller relative to the packaging paper is a technical problem that urgently needs to be solved in the field.

[0032] The defects existing in the above solutions are the results obtained by the inventor after practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed by the present invention in this article for the above problems should be the contributions made by the inventor to the present invention during the disclosure process.

[0033] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0034] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0035] like Figures 1 to 6As shown, some embodiments provide a glass substrate packaging paper transmission mechanism, including: a workbench 1; the paper is suitable for horizontal movement on the upper surface of the workbench 1; in order to reduce the friction force when the paper moves on the workbench 1, the workbench 1 is provided with a driven roller below the paper, which is suitable for driving the driven roller to rotate circumferentially when the paper moves horizontally. A transmission roller 2 is rotatably arranged on the workbench 1, and a plurality of air holes 20 are opened in the circumferential direction of the outer wall; a driving motor 5 is arranged on one side of the workbench 1, and the transmission roller 2 is connected to the driving motor 5. The driving motor 5 is suitable for driving the driving roller to rotate circumferentially. An adsorption component 3 is arranged in the transmission roller 2, and is suitable for negative pressure adsorption of the paper to move toward the transmission roller 2; the adsorption component 3 is suitable for negative pressure adsorption of the paper to increase the friction force between the paper and the transmission roller 2, and the transmission roller 2 drives the paper to move when it rotates circumferentially. The detection member 4 is arranged above the paper and located on one side of the unloading section of the transmission roller 2; the detection member 4 includes: a support plate 41, which is arranged parallel to the workbench 1; a sensor 42, which is arranged at equal intervals on the lower bottom wall of the support plate 41, and the sensor 42 is electrically connected to the control module to detect whether there are cracks on the surface of the bent paper. Preferably, the sensor 42 is a visual sensor 42. After the paper is adsorbed by the negative pressure tube 33, the transmission roller 2 rotates to drive the paper to bend upward, and the upward bending of the paper can magnify the cracks on the surface of the paper. The sensor 42 is suitable for detecting whether there are cracks on the surface of the paper. Among them, the adsorption component 3 negatively adsorbs the paper so that it fits with the outer wall of the transmission roller 2, and the transmission roller 2 rotates circumferentially to drive the paper to move horizontally; the paper is adsorbed by the negative pressure of the adsorption component 3 and bends upward, and the detection member 4 is suitable for detecting whether there are cracks on the surface of the paper. By setting the adsorption component 3, when the paper moves to the bottom of the transmission roller 2, there is a gap between the paper and the outer wall of the transmission roller 2, and the negative pressure tube 33 negatively adsorbs the paper, causing it to move toward the outer wall of the transmission roller 2 to increase the friction between the paper and the transmission roller 2. The transmission roller 2 rotates to drive the paper to move, avoiding the traditional situation where the transmission roller 2 rotates idly relative to the paper. In the process of negative pressure adsorption of the paper, the negative pressure tube 33 can also clean the dust on the surface of the paper; the paper is bent upward by the negative pressure adsorption, which can magnify the cracks on the surface of the paper, and improve the detection accuracy of the detection element 4 on the paper.

[0036] Reference Figure 4The adsorption component 3 includes: a positioning tube 31, which is arranged inside the transmission roller 2, and a plurality of annular grooves 34 are opened in the circumferential direction of the outer wall; preferably, a negative pressure pump is arranged at the bottom of the workbench 1, and the negative pressure pump is connected with the positioning tube 31, and the negative pressure pump is suitable for negative pressure suction of the air in the positioning tube 31. A positioning ring 32 is sleeved in the annular groove 34 and rotates relative to the positioning tube 31; the negative pressure tube 33 is suitable for driving the positioning ring 32 to make it rotate in a pendulum-like manner in the annular groove 34. One end of the negative pressure tube 33 is arranged on the outer wall of the positioning ring 32, and the other end is in contact with the inner wall of the transmission roller 2 and is adapted to the air hole 20; after the negative pressure tube 33 is connected with the air hole 20, the positioning tube 31 negatively suctions the air in the negative pressure tube 33, so that the paper moves toward the outer wall of the transmission roller 2.

[0037] The negative pressure tube 33 is a metal part, and the negative pressure tube 33 is suitable for sliding on the inner wall of the transmission roller 2. When the paper does not move below the transmission roller 2, several of the negative pressure tubes 33 have different angles with the horizontal plane; at this time, at least two negative pressure tubes 33 are perpendicular to the horizontal plane, at least two negative pressure tubes 33 have an angle of 30 degrees with the horizontal plane, and at least two negative pressure tubes 33 have an angle of 60 degrees with the horizontal plane. Furthermore, the bottom wall of each of the annular grooves 34 is provided with an electromagnetic component 36, and the electromagnetic component 36 is magnetically connected to the negative pressure tube 33.

[0038] The electromagnetic components are sequentially located directly below, obliquely below, and near the side wall of the detection component 4 of the positioning tube 31. The arrangement of the electromagnetic components 36 can ensure that when the paper does not move below the transmission roller 2, the negative pressure tubes 33 are at different angles with the horizontal plane; and when the electromagnetic components 36 are powered off, the power-off method here can be electrically controlled or manually controlled. The magnetic attraction of the electromagnetic components 36 to the negative pressure tube 33 disappears, and the negative pressure tube 33 is suitable for pendulum-like rotation relative to the positioning tube 31.

[0039] Reference Figure 5 The bottom wall of the annular groove 34 is provided with an adjustment hole 35, the adjustment hole 35 faces the workbench 1, and the opening size of the adjustment hole 35 is larger than the inner diameter of the negative pressure tube 33. The adjustment hole 35 is in a water drop shape, and the opening spacing of the adjustment hole 35 gradually decreases from the direction directly below the positioning tube 31 to the direction of the detection member 4.

[0040] When the paper moves to the bottom of the transmission roller 2, the negative pressure tube 33 connects the air hole 20 and the adjustment hole 35, and the negative pressure pump sucks the air in the negative pressure tube 33. The negative pressure tube 33 is suitable for negative pressure adsorption of the paper, so that it moves toward the outer wall of the transmission roller 2 to increase the friction between the paper and the transmission roller 2, and the transmission roller 2 rotates circumferentially to drive the paper to move horizontally; when the paper is adsorbed and bent toward the direction of the transmission roller 2, the horizontal movement of the paper is suitable for driving the corresponding negative pressure tube 33, so that the negative pressure tube 33 rotates like a pendulum relative to the positioning tube 31, and the negative pressure tube 33 gradually swings from the bottom of the positioning tube 31 toward the direction of the detection member 4, and the positioning ring 32 gradually closes the adjustment hole 35. At this time, the negative pressure suction force of the negative pressure tube 33 on the paper gradually decreases until the adjustment hole 35 is closed, and the negative pressure tube 33 loses the negative pressure suction force on the paper, and the negative pressure tube 33 swings downward to return to its original position under the action of gravity.

[0041] Some embodiments provide a glass substrate packaging paper transmission mechanism, including: A workbench 1; a driving roller 2, which is rotatably arranged on the workbench 1 and has a plurality of air holes 20 circumferentially opened on its outer wall; an adsorption component 3, which is arranged in the driving roller 2 and is suitable for negative pressure adsorption of paper to move toward the driving roller 2; the adsorption component 3 includes: a positioning tube 31, which is arranged inside the driving roller 2 and has a plurality of adjustment holes 35 opened on its outer wall; a positioning ring 32, which is sleeved on the outer wall of the positioning tube 31 and rotates relative to the positioning tube 31; a negative pressure tube 33, one end of which is arranged on the outer wall of the positioning ring 32 and extends radially along the positioning ring 32, and the negative pressure tube 33 is suitable for connecting the adjustment hole 35 with the air hole 20; wherein, when the paper has not moved to the bottom of the driving roller 2, the plurality of the negative pressure tubes 33 have different angles with the horizontal plane; after the adjustment hole 35 is connected with the air hole 20, the positioning tube 31 negatively sucks the air in the negative pressure tube 33 to move the paper toward the outer wall of the driving roller 2.

[0042] Furthermore, the adjustment hole 35 faces the workbench 1, and the opening size of the adjustment hole 35 is larger than the inner diameter of the negative pressure tube 33; the adjustment hole 35 is teardrop-shaped, and the opening spacing of the adjustment hole 35 gradually decreases from the unloading section side of the transmission roller 2 located directly below the positioning tube 31.

[0043] Furthermore, an electromagnetic component 36 is provided on the bottom wall of each annular groove 34 , and the electromagnetic component 36 is magnetically connected to the negative pressure tube 33 ; several of the electromagnetic components are sequentially located directly below, obliquely below, and close to the side wall of the positioning tube 31 .

[0044] Some embodiments provide a transmission process of a transmission mechanism, the transmission process comprising: The adsorption component 3 performs negative pressure suction to adsorb the paper with negative pressure, so that the paper moves toward the outer wall of the transmission roller 2, and the transmission roller 2 rotates circumferentially to drive the paper to move; When the paper moves, it drives the negative pressure tube 33 of the adsorption assembly 3 to swing relative to the positioning tube 31; During the process of the paper being negatively pressured by the negative pressure tube 33, the driving roller rotates circumferentially to bend the paper, and the detection element 4 is suitable for detecting whether there is a crack on the surface of the paper at the bending surface; The negative pressure tube 33 swings relative to the positioning tube 31, and the negative pressure suction force of the negative pressure tube 33 on the paper gradually decreases until the paper is separated from the negative pressure suction force of the negative pressure tube 33; The negative pressure tube 33 is reset and swung under the action of gravity until the negative pressure tube 33 is located directly below the positioning tube 31 .
