Description

Technical Field

[0001] The utility model belongs to the technical field of LED crystal film screen mounting structures, in particular to an LED crystal film screen mounting structure. Background Art

[0002] LED crystal film screens use flexible substrates, such as polyester film or polyimide film, instead of traditional rigid glass or metal substrates, which allows LED screens to be more easily bent, folded and installed on irregular surfaces. Due to the characteristics of the flexible design, LED crystal film screens can be applied to a wider variety of scenarios, such as curved displays, special shape installation requirements, etc., expanding the application field of LED display technology. However, LED crystal film screens usually use flexible polyester film or polyimide film as a substrate. This material itself is soft, and the LED chips or modules need to be firmly fixed on it through mounting technology to prevent them from moving or being damaged during use. The mounting process usually involves protection and packaging steps to ensure that the LED chips are protected from environmental influences and mechanical damage, while improving their reliability and durability in various application scenarios.

[0003] However, during the use of the existing LED crystal film screen mounting structure, a large number of bubbles may remain inside the sealant. These bubbles will reduce the filling density of the sealant and affect its sealing performance. During long-term use, external moisture may penetrate through the weak area where the bubbles are located, causing the LED chip to become damp, affecting its luminous effect and lifespan.

During long-term use, external moisture may penetrate through the weak area where the bubbles are located, causing the LED chip to get damp, affecting its luminous effect and lifespan is solved.

[0005] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0006] The utility model is a LED crystal film screen mounting structure, comprising a rectangular support plate 1, on which a rolling mechanism and a supporting mechanism are arranged;

[0007] A LED crystal film screen is provided at the rear side of the first rectangular support plate. The rolling mechanism includes a rotating component and a displacement component. The rotating component includes two trapezoidal chutes opened at the rear side of the first rectangular support plate. A first slider is slidably connected to the inner wall of the lower trapezoidal chute, and a second slider is slidably connected to the inner wall of the upper trapezoidal chute.

[0008] Further, a rack is fixedly connected to the rear side of the first rectangular support plate, and a gear is fixedly connected to the extending portion at the top side of the rotating shaft. The gear meshes with the rack.

[0009] Further, the displacement component includes two second rectangular support plates fixedly connected to the rear side of the first rectangular support plate. A reciprocating lead screw is rotatably connected between the two second rectangular support plates. The right side of the reciprocating lead screw rotatably penetrates the outer wall of the second rectangular support plate on the right side and extends to the outside. The reciprocating lead screw threadedly penetrates the first slider, and a motor is fixedly connected to the extending portion on the right side of the reciprocating lead screw.

[0010] Further, the support mechanism includes a first support component and a second support component. The first support component includes a plurality of circular grooves opened on the first rectangular support plate, and a connecting rod penetrates through each of the plurality of circular grooves.

[0011] Further, a limiting block is fixedly connected to the rear side of each of the plurality of connecting rods, and a suction cup is fixedly connected to the rear side of each of the plurality of limiting blocks.

[0014] The utility model has the following beneficial effects:

[0015] 1. By setting up a rolling mechanism, after the pressing roller contacts the LED crystal film screen, start the motor. The motor drives the reciprocating lead screw to rotate, thereby driving the pressing roller on the rotating shaft to move left and right through the first slider. When the pressing roller moves left and right, it will drive the pressing roller on the rotating shaft to rotate under the action of the rack and gear. The left and right movement of the pressing roller can cover the entire sealing area of the LED crystal film screen, ensuring that the sealant can be evenly pressed at each position, avoiding the situation of insufficient local pressing or excessive pressing, making the pressing effect more comprehensive and uniform. The rotation of the pressing roller while moving left and right can further enhance the pressing effect, thereby better removing the bubbles in the sealant, making the combination of the sealant with the wafer and the crystal film screen closer and firmer.

[0028] Please refer to Figures 1-5As shown in the figure, the utility model relates to a mounting structure for an LED crystal film screen, which includes a rectangular support plate 1. A rolling mechanism 2 and a support mechanism 3 are arranged on the rectangular support plate 1. An LED crystal film screen 101 is arranged at the rear side of the rectangular support plate 1.

The top of the rotating shaft 214 rotatably penetrates through the outer wall of the second slider 213 and extends to the outside. A pressing roller 215 is fixedly connected to the outer wall of the rotating shaft 214. A rack 216 is fixedly connected to the rear side of the rectangular support plate 1. A gear 217 is fixedly connected to the extending part on the top side of the rotating shaft 214. The gear 217 meshes with the rack 216. The displacement component 22 includes two rectangular support plates 221 fixedly connected to the rear side of the rectangular support plate 1. A reciprocating lead screw 222 is rotatably connected between the two rectangular support plates 221.
