[0002] Die bonding is a crucial step in display manufacturing, involving the precise attachment of LED chips or other semiconductor chips to a substrate. The quality of this process directly impacts the performance and reliability of the final product.

[0003] However, in existing technologies, most display screen die bonding baking air ducts are fixedly installed at the top inside the baking oven, making it inconvenient to adjust the position of the air ducts according to needs. This reduces the effect of display screen die bonding baking and increases the baking time. Moreover, the temperature of the display screen die bonding components is high after baking, and workers are prone to burns if they take them out directly, posing a certain safety hazard. In addition, the bottom of the traditional placement plate is sealed, which can only bake the display screen die bonding components on one side, resulting in an imperfect baking effect and thus reducing the curing effect of the display screen die bonding components. Utility Model Content

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0043] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0044] Example 1, such as Figure 1-4 As shown, this utility model provides a die bonding baking device for display screen processing, including: baking oven 1, door panel 101, baking assembly, and placement assembly;

[0045] The baking assembly includes: a hot air blower 103 fixedly installed at the top center of the baking oven 1, the output end of the hot air blower 103 passing through the baking oven 1; a telescopic tube 114 fixedly installed at the top center of the interior of the baking oven 1, the telescopic tube 114 being fixedly connected to the output end of the hot air blower 103; a guide tube 115 fixedly installed at the bottom of the telescopic tube 114; multiple connecting tubes 106 fixedly installed at the lower end of the guide tube 115; two annular tubes 105 fixedly installed on the outer surface of the connecting tubes 106; multiple air guide heads 107 fixedly installed at the bottom of the annular tubes 105; an air guide box 116 fixedly installed at the bottom of the air guide tube 115; multiple air guide plates 118 fixedly installed at the bottom of the air guide box 116; electric push rods 104 fixedly installed on both sides of the top of the baking oven 1, the output end of the electric push rod 104 passing through the baking oven 1 and fixedly connected to one of the annular tubes 105; and a transparent plate 102 fixedly installed on the outer surface of the door panel 101 near the upper end.

[0046] In this embodiment, two electric push rods 104 are simultaneously activated to drive the annular tube 105 and the air guide tube 115 to adjust up and down as needed. The positions of the annular tube 105 and the air guide tube 115 are adjusted according to requirements. The two electric push rods 104 are the same in model and power, so their synchronous movement can be controlled to better solidify the display screen die-bonding components. When the air guide tube 115 moves, it drives the telescopic tube 114 to extend and retract, which improves the hot air delivery. The hot air blower 103 delivers hot air to the telescopic tube 114, and then through the telescopic tube 114, it is transmitted to the interior of the air guide tube 115. Multiple connecting pipes 106 are fixedly installed at the lower end of the air guide tube 115, and the air is transported through the multiple connecting pipes 106. Hot air can be diffused into the interior of the annular tube 105. Multiple air guides 107 are fixedly installed on the outer surface of the annular tube 105. The lower end of the air guide 107 is inclined to prevent hot air from blowing directly onto the display die bonding assembly and damaging some components. The air guide box 116 fixedly installed at the bottom of the air guide tube 115 can diffuse the hot air, making the hot air diffuse more evenly into the interior of the baking oven 1, so that the internal temperature is uniform. Multiple air guide plates 118 are fixedly installed at the bottom of the air guide box 116. The air guide plates 118 are inclined to prevent hot air from blowing directly onto the display die bonding assembly. The curing effect of the display die bonding assembly can be observed through the transparent plate 102 installed on the outer surface of the door panel 101.

[0047] Example 2, as Figure 1-4As shown, the placement assembly includes: a baking table 108 fixedly installed at the lower end of the oven 1; a T-shaped groove 117 is provided at the center of the baking table 108 near the upper end; a T-shaped plate 109 is movably embedded inside the T-shaped groove 117; a circular placement box 111 is fixedly installed at the top center of the T-shaped plate 109; a circular hollow plate 112 is fixedly installed at the center of the circular placement box 111, with a certain gap between it and the bottom of the circular placement box 111; multiple air vents 113 are provided on the outer surface of the circular placement box 111 near the lower end; and a handle 110 is fixedly installed on one side of the T-shaped plate 109.

[0048] In this embodiment, the display die bonding assembly to be cured is placed on a circular perforated plate 112. There is a gap between the circular perforated plate 112 and the bottom of the circular placement box 111. Multiple air vents 113 are opened on the outer surface of the circular placement box 111 near the lower end. Hot air blown out by the hot air blower 103 enters the interior of the circular placement box 111 through the air vents 113. The hot air passing through the circular perforated plate 112 can bake and cure the other side of the display die bonding assembly, which improves the die bonding effect. Double-sided baking helps to ensure that each layer can be fully cured and reduces the risk of delamination. The handle 110 can be used to pull the T-shaped plate 109 to take the circular placement box 111 out of the oven 1, making it easier to remove the display die bonding assembly and improving safety.

[0049] Working principle: Simultaneously activating two electric push rods 104 drives the annular tube 105 and the air guide tube 115 to adjust vertically. The positions of the annular tube 105 and the air guide tube 115 are adjusted as needed to better solidify the display screen's die-bonding components. As the air guide tube 115 moves, it drives the telescopic tube 114 to extend and retract, improving hot air delivery. The hot air blower 103 delivers hot air to the telescopic tube 114, which then transmits it to the interior of the air guide tube 115. Multiple connecting pipes 106 are fixedly installed at the lower end of the air guide tube 115, allowing hot air to diffuse into the annular tube 105. Multiple air guides 107 are fixedly installed on the outer surface of the tube 105. The lower end of the air guide 107 is inclined to prevent hot air from blowing directly onto the display die bonding assembly and damaging some components. The air guide box 116 fixedly installed at the bottom of the air guide tube 115 can diffuse the hot air and make the hot air diffuse more evenly into the interior of the oven 1, so that the internal temperature is uniform. Multiple air guide plates 118 are fixedly installed at the bottom of the air guide box 116. The air guide plates 118 are inclined to prevent hot air from blowing directly onto the display die bonding assembly. The curing effect of the display die bonding assembly can be observed through the transparent plate 102 installed on the outer surface of the door panel 101.

[0050] The display die bonding assembly to be cured is placed on the circular cutout plate 112. There is a gap between the circular cutout plate 112 and the bottom of the circular placement box 111. The outer surface of the circular placement box 111 near the lower end has multiple air vents 113. Hot air blown out by the hot air blower 103 enters the interior of the circular placement box 111 through the air vents 113. The hot air passing through the circular cutout plate 112 can bake and cure the other side of the display die bonding assembly, which improves the die bonding effect. Double-sided baking helps to ensure that each layer can be fully cured and reduces the risk of delamination. The handle 110 can be used to pull the T-shaped plate 109 to take the circular placement box 111 out of the oven 1, making it easier to remove the display die bonding assembly and improving safety.

[0051] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
