Description

Technical Field

[0001] This utility model relates to the field of liquid crystal display module technology, and in particular to a packaging structure for preventing misplacement of liquid crystal display modules. Background Technology

[0002] LCD display modules contain various components and screens, all of which are relatively fragile and prone to breakage, especially at their edges and corners. Therefore, they require protection during shipping and transit to minimize transportation damage. Currently, blister trays are used to secure and protect LCD display modules. A blister tray is a plastic container with specific grooves made from rigid plastic sheets (such as PVC or PET) using a thermoforming process. It is primarily used to secure electronic components and precision instruments, preventing damage from shaking or collisions during transport. Its structural design precisely adapts to the shape of the product, and the grooves effectively prevent displacement or friction damage during transport, while also serving a display function.

[0003] However, in recent years, with the increasing variety of LCD display product styles, some circular display module structures have emerged. These modules have a circular cover plate on the front and FPC and other components attached to the back, with the back structure completely obscured by the circular cover plate. According to customer requirements, these circular products need to be shipped with the cover plate facing upwards and the back components facing downwards in a blister tray. However, because these products appear identical from all angles and lack clear markings to differentiate placement angles, it's difficult to accurately position them properly when loading them onto the blister tray. This can lead to misplacement or even reversed placement, causing FPC distortion or tearing of the display module's bonding points during transport, resulting in functional defects. Adding a positioning structure at the handle of the protective film on the front of the cover to lock it into place with the blister tray would require increased rigidity, increasing costs. Furthermore, the protective film on the front of the cover needs to be removed during manufacturing; re-attaching it would not meet accuracy requirements and would hinder rapid positioning later. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the existing technology by providing a packaging structure for shipping liquid crystal display modules to prevent misplacement.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A packaging structure for preventing misplacement of liquid crystal display modules includes a liquid crystal display module and a blister tray. The liquid crystal display module comprises a module body, a cover plate, an FPC (Flexible Printed Circuit), and foam. The cover plate is attached to the front side of the module body, and the foam is attached to the back side of the module body. The FPC connects to the module body and is bonded to the bonding area of ​​the foam. A release film covers the non-bonding area of ​​the foam. A tear handle protruding from the edge of the cover plate is provided on the edge of the release film, and a positioning hole is provided on the tear handle. The blister tray has several module placement slots, and positioning posts are provided in the module placement slots. When the liquid crystal display module is placed in a module placement slot, the positioning posts and positioning holes can cooperate to fix the position and angle of the liquid crystal display module in the blister tray.

[0007] Furthermore, the module placement slot includes a main slot and a positioning slot that are interconnected. The main slot is used to place the liquid crystal display module, and the positioning post is disposed in the positioning slot.

[0008] Furthermore, the positioning post is positioned at the center of the positioning groove.

[0009] Furthermore, the positioning hole is located at the center of the tearing handle.

[0010] Furthermore, the shape and size of the main groove are matched with the shape and size of the cover plate.

[0011] Furthermore, the shape and size of the positioning groove are matched with the shape and size of the tearing hand.

[0012] Furthermore, both the positioning hole and the positioning post are circular.

[0013] Furthermore, the release film is a blue film.

[0014] Furthermore, the height of the positioning post is 2-3mm.

[0015] Furthermore, the blister tray is provided with eight module placement slots.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] By employing a segmented release film design on the foam covering the back of the FPC product, the release film on the adhesive area of ​​the foam surface is first peeled off during FPC assembly. The remaining release film has positioning holes on its tear-off handle. Corresponding positioning posts are provided on the blister tray to mate with these positioning holes, used to position the angle and orientation of the display module on the tray. Through this positioning and mating design between the display module and the blister tray, even without obvious markings on the display module surface, the positioning holes and posts ensure a consistent orientation of the product within the packaging, preventing damage to components and glass due to misplaced products, thus avoiding product failure.

[0018] Other features and advantages of this invention will be set forth in the following description or may be learned by practicing this invention. Attached Figure Description

[0026] like Figure 1-3 As shown, a packaging structure for preventing misplacement of liquid crystal display modules includes a liquid crystal display module and a blister tray.

[0027] like Figure 2 As shown, the liquid crystal display module includes a module body 2, a cover plate 3, an FPC 4, and foam 5. The cover plate 3 is attached to the front side of the module body 2, and the foam 5 is attached to the back side of the module body 2. The FPC 4 is connected to the module body 2 and is bonded to the bonding area 51 of the foam 5. A release film 6 is covered on the non-bonding area 52 of the foam 5. The edge of the release film 6 is provided with a tear handle 7 protruding from the edge of the cover plate 3, and the tear handle 7 is provided with a positioning hole 8.

[0028] like Figure 1 As shown, the blister tray 1 is provided with several module placement slots, including a main slot 10 and a positioning slot 11 that are interconnected. The main slot 10 is used to place the liquid crystal display module, and the positioning slot 11 is provided with a positioning post 9. The shape and size of the main slot 10 match the shape and size of the cover plate 3, and the shape and size of the positioning slot 11 match the shape and size of the tear handle 7. When the liquid crystal display module is placed in the main slot 10 and the release film 6 is placed in the positioning slot 11, the positioning post 9 and the positioning hole 8 can be connected to fix the position and angle of the liquid crystal display module in the blister tray 1.

[0029] Preferably, the positioning post 9 is located at the center of the positioning groove 11, and the height of the positioning post 9 is 2-3mm. The positioning hole 8 is located at the center of the tear handle 7. Both the positioning hole 8 and the positioning post 9 are circular.

[0030] like Figure 3 As shown, the release film 6 covering the surface of foam 5 is segmented, consisting of a portion covering the bonding area 51 and a portion covering the non-bonding area 52. Before bonding FPC4, the release film 6 covering the bonding area 51 needs to be removed, leaving the release film on the non-bonding area 52 intact.

[0031] Preferably, the release film 6 is a blue film. The release material coated on the surface of the blue film makes its release force uniform and controllable, the peeling process stable and leaves no residue, making it suitable for high-precision process requirements. Furthermore, the blue film has high hardness and flatness, making it suitable for the positioning and placement of LCD display modules.

[0032] Preferred, such as Figure 1 As shown, the rectangular blister tray 1 has eight module placement slots. The module placement slots in each column are staggered to make full use of the space on the blister tray 1 and place more products.

[0033] The usage process and principle of the above embodiments are as follows:

[0034] First, before bonding the FPC4, the release film 6 covering the bonding area 51 needs to be removed, leaving the release film 6 on the non-bonding area 52. The FPC4 is then bonded to the back of the module body 2. Next, the LCD module is placed in the main slot 10 of the module placement groove. By adjusting the orientation angle of the LCD module, the tear handle 7 of the release film 6 is placed into the positioning slot 11. At this point, the positioning post 9 and the positioning hole 8 can be properly engaged, ensuring the consistency of the LCD module's position and angle in the blister tray 1. This prevents the LCD modules from mixing or reversing during packaging, avoids quality problems such as damage during product packaging and transportation, and improves the yield rate of products reaching the customer. This design also eliminates the step of bonding the film on the front of the module, saving costs and improving efficiency.

[0035] The above specific embodiments are only for illustrating the technical concept and structural features of this utility model, and are intended to enable those skilled in the art to implement them. However, the above content does not limit the protection scope of this utility model. Any equivalent changes or modifications made in accordance with the spirit and essence of this utility model shall fall within the protection scope of this utility model.
