Description

TECHNICAL FIELD

[0001] The utility model relates to transportation technical field, especially a kind of anti-deviation mechanism. BACKGROUND

[0002] With the continuous progress of display technology, ultra-thin liquid crystal panel is transported by virtue of its light, high definition, low power consumption and other significant advantages, in the production process of ultra-thin liquid crystal panel, transportation link is a crucial link. From the cutting of panel, detection to final assembly, it needs to go through multiple processes and different production equipment, which requires the panel to be accurately and stably transported between various stations to ensure the continuity of production process and the stability of product quality.

[0003] In the transportation of ultra-thin liquid crystal panel, roller transportation is a common and efficient way. The roller transportation system is usually composed of multiple parallel rollers, and the panel is placed on the rollers and moved forward by the rotation of the rollers. However, in the actual production process, due to various factors, the panel will be subjected to uneven friction when transported on the rollers, which will gradually change the direction of the panel and cause the panel to deviate during transportation. In order to effectively solve this problem, a common anti-deviation method is to use mechanical limiting device. This device limits the movement trajectory of the panel by setting physical boundaries, thereby preventing it from deviating. Unfortunately, this mechanical limiting method is a rigid contact between the liquid crystal panel, and during the transportation process, the mechanical limiting device and the edge of the panel will produce frequent friction and collision as the panel moves continuously. Especially for ultra-thin liquid crystal panel, which is a fragile and easily damaged component with precise structure and fragile texture, the wear and tear caused by this rigid contact is particularly prominent, which seriously affects the quality and service life of the panel.

[0004] Therefore, the present application develops an anti-deviation mechanism to solve the problems in the prior art. UTILITY MODEL CONTENT

[0027] The content of the utility model will be further described in detail in combination with specific embodiments:

[0028] As Figures 1-3 Shown, an anti-deviation mechanism, including multiple rotating mechanisms 1, and multiple rotating mechanisms 1 are arrayed along the first direction.Each rotating mechanism 1 includes drive shaft 11 and multiple rotating parts 12 fixedly sleeved on drive shaft 11. Wherein, drive shaft 11 is stably supported by multiple bearing seats 2, to ensure that it can rotate smoothly.When the product is placed above rotating mechanism 1, the product will be in contact with the outer surface of each rotating part 12, under the drive of drive shaft 11, rotating part 12 starts to rotate, relies on the friction between rotating part 12 and product, makes product move along the first direction, realizes the transmission of product on production line.Specifically, as Figure 5 Shown, the axial direction of drive shaft 11 is X direction, and the first direction is Y direction perpendicular to X direction.

[0029] In this embodiment, as Figures 1-2As shown, multiple rotating parts 12 on each rotating mechanism 1 are mounted on the drive shaft 11 in two opposite directions, and the number of rotating parts 12 mounted in both directions is the same. When the product is placed above the rotating mechanism 1 and moves along the first direction as the rotating parts 12 rotate, the rotating parts 12 in different mounting directions contact the product and apply friction, causing the product to be subjected to a force at a certain angle to the first direction. Because the number of rotating parts 12 in the two opposite mounting directions is the same, the magnitudes of the two forces at an angle to the first direction experienced by the product during movement are equal, thus forming a dynamic balance correction mechanism to prevent the product from shifting during transportation. Because the rotating part 12 has a clamping part 122 at its center, and the clamping part 122 protrudes to one side, the force on both sides of the rotating part 12 along the axial direction is uneven, and during movement, there is a situation where it tilts towards the clamping part 122. Figure 6 As shown, at this time, the rotating part 12 generates an upward support force on the product. This support force will generate a first component force and a second component force. The first component force is set along the axial direction of the drive shaft 11. Therefore, if the installation directions of the rotating parts 12 are all the same, the resultant force of the first component force will be in one direction, causing the product to move in the Y direction while also moving in the X direction. However, the rotating parts 12 are installed on the drive shaft 11 in two opposite directions, and the number of rotating parts 12 installed in the two directions is the same. The first component force will cancel each other out, causing the product to move in the Y direction and avoiding deviation of the product movement.

[0030] Furthermore, the rotating part 12 located at the outermost position of the drive shaft 11 has an installation direction opposite to that of the rotating part 12 immediately adjacent to it. At the same time, all rotating parts 12 located between any two adjacent bearing seats 2 have the same installation direction, which makes the product subject to more uniform friction during transportation and reduces product shaking and swaying caused by the difference in the installation direction of the rotating parts 12. In addition, the rotating parts 12 on both sides of the bearing seat 2 have opposite installation directions, which has a corrective effect on the product, ensuring the stability of the product during transportation and ensuring that the product will not deviate during transportation.

[0031] like Figures 3-4As shown, if the driving shaft 11 and the rotating part 12 are displaced during the product transportation, the friction force of the rotating part 12 on the product will change, so that the friction force on the product cannot be balanced, and the product will be offset or vibrated. Therefore, in the embodiment, the rotating part 12 comprises a rotating body 121 and a clamping part 122. The rotating body 121 is uniformly provided with a plurality of deformation parts 123 at intervals along the inner contour thereof, and the deformation parts 123 protrude from the surface of the rotating body 121 in the axial direction of the driving shaft 11. The clamping part 122 is installed on the outer surfaces of all the deformation parts 123 in a sleeving manner. In addition, the clamping part 122 is provided with a connecting structure (not shown in the figure) for adjusting the tightness at the two ends thereof. The connecting structure used in the application is a screw assembly. In the initial state, when the screw assembly is not tightened, the inner wall surface of the clamping part 122 closely fits on the outer surfaces of the deformation parts 123. At the same time, since the clamping part 122 is not completely fixed at this time, there is a certain adjustment gap 3 at the two ends thereof. When the rotating part 12 needs to be installed on the driving shaft 11 or the tightness needs to be adjusted, the operator can change the tightness of the clamping part 122 by rotating the screw assembly. With the tightening of the screw assembly, the clamping part 122 will gradually shrink, and the pressure of the inner wall surface of the clamping part 122 on the deformation parts 123 will increase, so that the deformation parts 123 will be elastically deformed to a certain extent, and the rotating part 12 will be more tightly fixed on the driving shaft 11 as a whole, effectively preventing the rotating part 12 from loosening or sliding on the driving shaft 11, and further preventing the product from being offset during the movement.

[0032] The above embodiments are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and implement it, and cannot limit the protection scope of the present application. For those skilled in the art, it is obvious that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present application. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
