Abstract

An injection-moulded box for liquid crystal display panels, comprising side walls (100) and a bottom surface plate (200). The side walls (100) surround the bottom surface plate (200), wherein the bottom surface plate (200) comprises an inner bottom plate (210) and an outer bottom plate (230), and reinforcing structures (220) are arranged between the inner bottom plate (210) and the outer bottom plate (230). The injection-moulded box for the liquid crystal display panels has greatly increased bearing capacity and less tendency to deform. The problem that the quality of the liquid crystal display panels is affected by mutually overlaying the injection-moulded boxes is avoided. The number of times for which the injection-moulded boxes can be recovered is increased. The packaging cost is reduced. The problem of the injection-moulded box with a large size being heavy is solved.

Liquid crystal panel injection box

Technical field

The invention relates to the field of manufacturing and packaging of liquid crystal panels, in particular to a liquid crystal panel injection molding box.

Background technique

In the electronics industry, the production assembly of electronic products requires complex supply chain support. Usually, parts of electronic products are mass-produced, manufactured in different places, transported, and transported to an assembly factory for assembly. In the field of liquid crystal display devices, liquid crystal panels are the core components of liquid crystal display devices, and the reliability of packaging needs to be considered in transportation. However, in the loading and transportation process, the packaging boxes with the liquid crystal panels are usually stacked on each other, and the lower packaging boxes are squeezed by the multi-layer stacked packaging boxes, which cannot withstand external pressure due to the conventional packaging method, resulting in liquid crystals. The panel is deformed, causing unnecessary losses to the enterprise.

The bottom panel of the traditional injection box adopts a T-shaped rib structure, and the bottom panel and the rib wall are thick. When the package is injection molded, the bottom panel is concave due to uneven shrinkage, and the time of carrying the product in the injection box increases, the bottom The concave depression of the panel is more and more serious, and the concave of the bottom panel causes the injection molding box to press the liquid crystal panel in the box when stacking, and the concave phenomenon of the bottom panel is difficult to avoid in the injection molding process of the packaging box, and at the same time, the bottom The concave injection box of the panel is not conducive to recycling, which increases the packaging cost. In addition, when carrying a large-sized liquid crystal panel, the package is often designed to have a large structural size, which increases the weight of the injection molding box, is inconvenient for the work of the operator, and affects work efficiency.

Summary of the invention

The technical problem to be solved by the invention is to provide a liquid crystal panel injection molding box, strengthen the structural strength of the bottom of the injection molding box, improve the flatness of the bottom of the injection molding box, save materials, and realize a large-sized and light-weight injection molding box.

In order to achieve the above object, the present invention adopts the following technical solutions:

A liquid crystal panel injection molding box comprising a side wall and a bottom panel, the side wall surrounding the bottom panel, wherein the bottom panel comprises an inner bottom plate and an outer bottom plate, and the inner bottom plate and the outer bottom plate are disposed There is a strengthening structure.

Further, the reinforcing structure is composed of a plurality of units and has a grid shape.

Further, each of the units includes a frame, and the frame connects the inner bottom plate and the outer bottom plate.

Further, the frame is a polygonal structure, and a space formed by enclosing the inner bottom plate and the outer bottom plate is hollow.

Further, the frame is quadrangular, and a plurality of the quadrilateral cells are connected to each other such that the cross section of the bottom panel has a continuous serpentine structure.

Further, the frame is hexagonal, and the hexagonal cells are connected in sequence, and the hexagonal cells are connected in a staggered manner, so that the reinforcing structure is in a honeycomb shape.

The beneficial effects of the invention:

The invention provides a liquid crystal panel injection molding box, which has the characteristics of simple structure, material saving, high flatness, compact structure and uniform force, so that the bearing capacity of the injection molding box is greatly improved, deformation is not easy, and the injection molding boxes are prevented from overlapping each other. And affect the quality of the LCD panel, increase the number of injection box recycling, reduce the package The cost of loading solves the problem of heavy-duty injection box.

detailed description

In order to better explain the technical features and structures of the present invention, the preferred embodiments of the present invention and the accompanying drawings are described in detail below.

Example 1

Referring to FIGS. 1 to 3 , a liquid crystal panel injection molding box includes a side wall 100 and a bottom panel 200 , the side wall 100 surrounding the bottom panel 200 , wherein the bottom panel 200 includes an inner bottom plate 210 and an outer bottom plate 230 . A reinforcing structure 220 is disposed between the inner bottom plate 210 and the outer bottom plate 230, and the reinforcing structure 220 is used to improve the structural strength and weight of the injection molding box.

The reinforcing structure 220 is composed of a plurality of units 221 in a grid shape. Each of the units 221 includes a frame 21 located inside the bottom panel 200, connecting the inner bottom plate 210 and the outer bottom plate 230 of the bottom panel 200, and forming a hollow region with the inner bottom plate 210 and the outer bottom plate 230. To reduce the weight of the injection box. The reinforcing structure 220 is designed into a grid-like structure, so that the injection box has high flatness, compact structure and uniform force, which greatly improves the bearing capacity of the injection box and is not easily deformed. At the same time, the interior of each unit 221 in the grid is a hollow structure. Helps save the bottom panel material, reduces weight, and solves The problem of heavy-duty injection box is heavier.

The reinforcing structure 220 is a polygonal grid, and the frame 21 of each unit 221 has a polygonal structure. In the design and manufacture process, the type, wall thickness and diameter of the frame 21 can be selected according to the number and weight of the liquid crystal carrying panels. In this embodiment, the frame 21 of each unit 221 of the reinforcing structure 220 is quadrangular, and a plurality of the quadrangular units 221 are connected to each other, so that the cross section of the bottom panel 200 has a continuous serpentine structure, and the middle portion of the mouth shape is hollow. Helps reduce the weight of the injection box.

Referring to FIG. 4, in this embodiment, the frame 21 of each unit 221 of the reinforcing structure 220 is hexagonal, the front and rear hexagonal units 221 are sequentially connected, and the left and right hexagonal units 221 are alternately connected, so that the reinforcing structure 220 is The honeycomb is located between the inner bottom plate 210 and the outer bottom plate 230 of the bottom panel 200. It can be known from the basic physics knowledge that the compressive strength of the box is provided by the four side walls, and the compressive strength generated by the intersection of the two side walls is the largest. It is reasonably inferred that when the number of sputum increases, the resistance generated by the box The greater the compressive strength, therefore, the hexagonal reinforcing structure 220 helps to increase the structural strength and load carrying capacity of the injection box.
