Description

Technical Field

[0001] The present invention relates to the technical field of liquid crystal display modules, and particularly to a plastic suction tray for a liquid crystal display module with PIN pins pointing upwards. Background Art

[0002] The plastic suction tray for a liquid crystal display module is made of a plastic hard sheet with a specific groove by a plastic suction process, and the liquid crystal display module is placed in the groove to play a role in protecting the liquid crystal display module. The structure of the cell of the existing plastic suction tray for a liquid crystal display module is as Figure 1 shown. The liquid crystal display module adopts a downward-embedded method of PIN pins in this cell, and the retaining walls are designed at the four corners of the cell. However, when the size of the PIN pins at the four corners of the liquid crystal display module from the glass edge is less than 4.5 mm, due to this too small size, there is not enough size in the cell of the plastic suction tray to design the retaining walls. In this way, during transportation or dropping, the liquid crystal display module cannot be effectively clamped and moved, causing the PIN pins of the liquid crystal display module to be deformed due to impact, and further resulting in poor appearance or quality problems of the liquid crystal display module. Currently, for such liquid crystal display modules with relatively extreme outer shapes, only soft packaging materials such as EPE foam or polystyrene foam can be selected, and these soft packaging materials have high costs, high mold opening costs, complicated manufacturing processes, high production costs, and high recycling costs, and are not the main selected materials for packaging. In view of the packaging of such liquid crystal display modules with relatively extreme outer shapes, it is necessary to solve the drawback that the retaining walls cannot be effectively designed in the traditional design from the design, and achieve the purpose of low material cost, recyclability and energy consumption reduction while meeting the transportation reliability of the product. Summary of the Invention

[0003] The problem to be solved by the present invention is that when the size of the PIN pins at the four corners of the liquid crystal display module from the glass edge is less than 4.5 mm, it is impossible to design the retaining walls in the cell of the plastic suction tray, and a plastic suction tray for a liquid crystal display module with PIN pins pointing upwards is provided.

[0004] To solve the above problems, the present invention is realized by the following technical solutions:

[0005] A plastic suction tray for a liquid crystal display module with PIN pins pointing upward, comprising a plastic suction tray body and at least one cell formed on the plastic suction tray body; each cell is a groove in the shape of a quadrilateral-like, and the left and right side walls of the groove are in contact with the two PIN-pin sides of the liquid crystal display module, and the front and rear side walls of the groove are in contact with the two non-PIN-pin sides of the liquid crystal display module; the left side wall of each cell is formed by connecting 6 left wall segments end to end; the first left wall segment in the first layer, i.e., the uppermost layer, is a vertical wall, the second left wall segment in the second layer is a horizontal wall, the third left wall segment in the third layer is an inclined wall, the fourth left wall segment in the fourth layer is a vertical wall, the fifth left wall segment in the fifth layer is a horizontal wall, and the sixth left wall segment in the sixth layer, i.e., the lowermost layer, is a vertical wall; the right side wall of each cell is formed by connecting 5 right wall segments end to end; the first right wall segment in the first layer, i.e., the uppermost layer, is a vertical wall, the second right wall segment in the second layer is an inclined wall, the third right wall segment in the third layer is a vertical wall, the fourth right wall segment in the fourth layer is a horizontal wall, and the fifth right wall segment in the fifth layer, i.e., the lowermost layer, is a vertical wall; the heights of the first left wall segment and the first right wall segment are equal, the heights of the third left wall segment and the second right wall segment are equal, the heights of the fourth left wall segment and the third right wall segment are equal, and the heights of the sixth left wall segment and the fifth right wall segment are equal.

[0006] In the above solution, the heights of the sixth left wall segment and the fifth right wall segment are higher than the overall height of the liquid crystal display module.

[0007] In the above solution, the inclination angles of the third left wall segment and the second right wall segment are equal and they are mirror-symmetrical to each other.

[0008] In the above solution, the included angle between the third left wall segment and the fourth left wall segment is 135°, and the included angle between the second right wall segment and the third right wall segment is also 135°.

[0009] In the above solution, the lengths of the fifth left wall segment and the fourth right wall segment are equal.

[0010] Compared with the prior art, the present invention has the following characteristics:

[0011] 1. The two sides of the cell in contact with the non-PIN-pin side of the liquid crystal display module adopt a ramp anti-slip tray design, which enables the PIN pins of the liquid crystal display module to be inserted into the cell with the PIN pins pointing upward, and the top ends of the PIN pins of the liquid crystal display module are effectively cleared, ensuring that the PIN pins of the liquid crystal display module will not hit the wall of the plastic suction tray, solving the problem that when more than two plastic suction trays are stacked, the bottom of the upper plastic suction tray hits the PIN pins of the liquid crystal display module inside the lower plastic suction tray, effectively improving the stacking operation tolerance and production first-pass rate, achieving efficient packaging, and ensuring the safety and reliability during transportation.

The blister material is common in the market and has a high market share. The production process is simple, the production cost is low, it can be recycled, and it can effectively reduce the packaging cost and recycling cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to specific examples.

[0018] Refer to Figure 2 , a blister tray for a liquid crystal display module with PIN pins pointing upwards, including a blister tray body 1. In this embodiment, the blister tray body 1 is made of PET material. Anti-drop strengthening structures, namely anti-misalignment corners 3, are provided at the four corners of the blister tray body 1. In addition, an upwardly convex stack tray support structure 4 is provided at the edge of the blister tray body 1. A number of cells 2 are arranged neatly in the middle of the blister tray body 1. Each cell 2 is a groove in the shape of a quadrilateral-like. The liquid crystal display module 5 is inserted into the cell 2, that is, the groove, with the PIN pins pointing upwards.

[0019] The front and rear side walls of each cell 2 are in contact with the two non-PIN pin sides, that is, the glass, of the liquid crystal display module 5. It can follow the existing structure and is not the focus of the present invention. The left and right side walls of each cell 2 are in contact with the two PIN pin sides, that is, the PIN pins, of the liquid crystal display module 5. This is the design focus of the present invention. In the present invention, the side view schematic diagram of each cell 2 is as Figure 3As shown, the left wall of each cell 2 is formed by connecting 6 left wall segments end to end, and the right wall of each cell 2 is formed by connecting 5 right wall segments end to end. For the left wall of each cell 2: The first left wall segment located in the first layer, i.e., the topmost layer, is a vertical wall; the second left wall segment located in the second layer is a horizontal wall; the third left wall segment located in the third layer is an inclined wall; the fourth left wall segment located in the fourth layer is a vertical wall; the fifth left wall segment located in the fifth layer is a horizontal wall; the sixth left wall segment located in the sixth layer, i.e., the bottommost layer, is a vertical wall. For the right wall of each cell 2: The first right wall segment located in the first layer, i.e., the topmost layer, is a vertical wall; the second right wall segment located in the second layer is an inclined wall; the third right wall segment located in the third layer is a vertical wall; the fourth right wall segment located in the fourth layer is a horizontal wall; the fifth right wall segment located in the fifth layer, i.e., the bottommost layer, is a vertical wall. The liquid crystal display module 5 is laid across the surfaces of the fifth left wall segment and the fourth right wall segment with the PIN pins facing upward.

[0020] To ensure the symmetry of the left and right side walls of each cell 2 for the convenience of embedding the liquid crystal display module 5, the heights of the first left wall segment and the first right wall segment are equal; the heights of the third left wall segment and the second right wall segment are equal; the heights of the fourth left wall segment and the third right wall segment are equal; the heights of the sixth left wall segment and the fifth right wall segment are equal; the lengths of the fifth left wall segment and the fourth right wall segment are equal; the inclination angles of the third left wall segment and the second right wall segment are equal and they are mirror-symmetrical. In this example, the included angle between the third left wall segment and the fourth left wall segment is 135°, and the included angle between the second right wall segment and the third right wall segment is also 135°.

[0021] The upper end of the first left wall segment is connected to the first right wall segment of the adjacent cell 2, and the upper end of the first right wall segment is connected to the first left wall segment of the adjacent cell 2. The lower end of the sixth left wall segment is connected to the lower end of the fifth right wall segment. In order to leave enough height space for the liquid crystal display module 5 embedded in the cell 2 of the blister tray when two blister trays are stacked, the heights of the sixth left wall segment and the fifth right wall segment are higher than the overall height of the liquid crystal display module 5, and it is preferably that the lower end of the sixth left wall segment is horizontally connected to the lower end of the fifth right wall segment.

[0022] The present invention rationally designs the cells 2 of the blister tray in combination with the outer shape of the liquid crystal display module 5, which can effectively improve the drawbacks existing in the traditional design where the PIN pins of the liquid crystal display module 5 face downwards. It enables the liquid crystal display module 5 to be installed in reverse, that is, the PIN pins point upwards. Since the thickness of the bottom end of the PIN pin of the liquid crystal display module 5, which is the end close to the glass substrate, is greater than the thickness of the top end of the PIN pin, and the strength of the bottom end of the L-shaped PIN pin is greater than the strength of the top end of the straight-line PIN pin, when the liquid crystal display module 5 is inserted into the cell 2 with the PIN pins facing upwards, the liquid crystal display module 5 can better abut against the side wall of the cell 2, and can ensure the embedding stability between the four sides of the liquid crystal display module 5 and the side wall of the cell 2, preventing the deformation of the PIN pins of the liquid crystal display module 5. In this way, there is no need to additionally add retaining walls around the cell 2, thus overcoming the problem that the liquid crystal display module 5 cannot be reasonably designed with retaining walls due to the too small distance between the four corners of the liquid crystal display module 5 and the glass edge.

[0023] It should be noted that although the embodiments described above of the present invention are illustrative, they are not limitations of the present invention. Therefore, the present invention is not limited to the above specific embodiments. Without departing from the principle of the present invention, any other embodiments obtained by those skilled in the art under the inspiration of the present invention are regarded as within the protection scope of the present invention.
