Description

Vibration alignment device for light guide plate

Technical Field

The application belongs to the technical field of light guide plate processing equipment, and particularly relates to a vibration alignment device for a light guide plate.

Background

The light guide plate (light guide plate) is formed by printing light guide points on the bottom surface of an optical acrylic/PC plate by using a material which has extremely high reflectivity and does not absorb light, such as laser engraving, grid engraving and UV screen printing, and sucking the stay of light emitted from a light source such as a lamp on the surface of the optical acrylic plate by using the optical acrylic plate, and when the light is incident on each light guide point, the reflected light is diffused in various angles (or directions) and then the reflection condition is destroyed and emitted from the front surface of the light guide plate. In addition, the light guide plate can uniformly emit light through various light guide points with different densities and different sizes.

Light guide plates are widely used in liquid crystal display light source systems and technical information about light guide plates is not lacking in the published chinese patent literature, and examples thereof are CN1187639C (light guide plate and method for manufacturing a mold thereof), CN100376955C (light guide plate and method for manufacturing the same), CN100389330C (method for manufacturing a light guide plate), CN100529874C (light guide plate) and CN101738676B (method for manufacturing a light guide plate), and so forth.

As known in the art, in the process of manufacturing the light guide plate, the microstructure units need to be transferred to the end surface of the light guide plate by a transfer device such as a thermal transfer wheel, for example, the patent application publication CN104369531B recommends "a heat transfer device and a transfer method for the end surface of the light guide plate", and the specific structure and method of the patent application can be seen in paragraphs 0028 to 0029 and examples 1 to 3. The technical effects of the four aspects summarized in the technical effects column of the specification can be objectively reflected by the patent proposal. But there are the following drawbacks: the proposal of the patent transfers the micro-mechanism to the end surface of the light guide plate piece by piece, so the transfer efficiency is relatively low, on one hand, the proposal is inconvenient to be suitable for the requirement of industrialized high-efficiency production of the light guide plate, and on the other hand, the maximum efficiency of the transfer device can not be exerted, thus the processing cost is high and the energy consumption is large.

In theory, if the microstructure can be transferred to the end surfaces of a stack of light guide plates at a time, it is needless to say that the transfer efficiency can be significantly improved and the aforementioned technical problem can be eliminated, but since the transfer process is located after the polishing process, that is, the end surfaces of the light guide plates to be transferred need to be polished by the polishing device first, and then the polished end surfaces of the light guide plates, that is, the polished surfaces, are transferred to the microstructure by the transfer device (typically, only one end surface needs to be polished and transferred). Specifically, after the end face polishing is completed, the light guide plate is typically transferred to a transfer station (i.e., a microstructure transfer station) by an in-line operator. However, since the technical requirements for the microstructure transfer are very strict, if the polished stack of light guide plates is transferred to the transfer station by manual transfer and is secondarily clamped, it is impossible to keep the end surfaces of the stack of light guide plates in a Ji Zheng state, so that the transfer process requirements cannot be met, that is, the problem of high yield of microstructure transfer is easily generated.

The foregoing problems are readily apparent if there has been a reasonably constructed and simple light guide plate alignment device that automatically aligns finished polished light guide plates into a stack.

Technical information of clamping the light guide plates is seen in the published chinese patent document, and typically, as recommended in the patent application publication No. CN106256497a, a "positioning jig for polishing a light guide plate" is to clamp a stack of light guide plates in a rectangular positioning seat, clamp a stack of light guide plates by a set of cylinders (four) and a pressing plate, and when polishing of a light guide plate at the bottom of the positioning seat is completed, a set of cylinders work in opposite directions and the pressing plate is simultaneously released, so that a light guide plate at the bottom of which polishing is completed is taken out from an elongated slot of the positioning seat by an on-line operator, then clamp a light guide plate again by a set of cylinders and pressing plate, polish an alternate polishing plate at the bottom of the positioning seat again by a polishing device, and repeat this until polishing of a stack of light guide plates is completed (see paragraph 0025 of the specification of the patent). However, this patent does not give a technical teaching of how the polished light guide plate is transferred to a transfer device in a state of being formed in a bundle. More typically, "an automatic positioning device for a light guide plate printing CCD", provided in CN205149165U, the structure of the patent scheme is: a baffle plate pushed by a positioning cylinder is arranged on the left side, the right side and the rear side of a supporting frame respectively, an opening is formed on the front side of the supporting frame, a positioning motor and a correcting motor are arranged at the bottom of the supporting frame, and two image sensors are arranged above the corresponding supporting frame; the working principle of the patent scheme is as follows: the light guide plate placed in the support frame is roughly positioned by the positioning cylinders arranged on the left side, the right side and the rear side of the support frame, the spatial position positioning information is transmitted to the positioning motor and the correction motor by the two image sensors, and the light guide plate is finely positioned under the work of the correction motor (see the specification of 0011 and 0014 of the patent).

The aforesaid CN205149165U provides a technical teaching for aligning a stack of light guide plates, and can objectively honor the technical effects described in paragraph 0006 of the specification, but the following drawbacks still exist in this patent scheme: firstly, because a continuous positioning measure is lacking in the process of transferring the bundle of light guide plates with the fine positioning to the transfer device, when the bundle of light guide plates is taken out from the support frame and clamped to the transfer station, the situation of shifting affecting the leveling still occurs, so that the printing quality of the microstructure is difficult to ensure; secondly, if the support frame and the finely aligned light guide plates are directly clamped on the transfer printing device, the leveling (alignment) effect of the light guide plates is guaranteed, but the bottom of the support frame is provided with a correction motor and a positioning motor, and two image sensors are arranged at the upper part of the support frame, and due to the existence of an electric circuit electrically connected with the correction motor and a pipeline connected with air inlets and air outlets of four positioning cylinders, interference situations can be generated on the transfer printing device, and on the other hand, the automatic positioning device for the CCD printing of the light guide plates is easy to damage and the whole automatic positioning device for the CCD printing of the light guide plates can be damaged, and especially the cooperative power chain among all stations can be damaged; thirdly, if the on-line operator transfers and clamps the bundle of light guide plates which are subjected to fine positioning on the transfer device, the transfer operation efficiency is greatly affected because the regularity of the light guide plates is ensured as much as possible in the transfer process, and the on-line operator is always in a highly stressed state with careful wings, which is not beneficial to constructing a loose operation environment and operation atmosphere.

There is a need for improvements in the art to which the present inventors have advantageously devised, and the technical solutions described below are developed in this context.
