Description

Technical Field

[0001] The present invention relates to the technical field of LCD screen patches, in particular to a buffer-type patch device for attaching polarizers to LCD screens. Background Art

[0002] LCD screens are mainly composed of two glass substrates, color filters, polarizers, drive circuits and backlights. Liquid crystal material is placed between the two glass substrates. The color filter contains red, green and blue pixels for displaying image colors. The polarizer controls the polarization direction of light, and the backlight provides light source. LCD screens usually contain two polarizers: the lower polarizer (close to the backlight side) converts the non-polarized light of the backlight into unidirectional polarized light; the upper polarizer (close to the viewing side) is perpendicular to the polarization direction of the lower polarizer (e.g., vertical direction). The attachment of polarizers to LCD screens is a key process in screen production or maintenance, and its accuracy directly affects the display effect of the screen. The core function of the polarizer is to filter polarized light in non-specific directions, and cooperate with the liquid crystal layer inside the LCD to realize the "light switch" function;

[0003] When performing press-attachment processing of polarizers on LCD screen substrates, the pressure plate directly applies unadjustable pressure to the polarizer, which is difficult to control and can easily damage the LCD screen and affect the patch effect.

[0030] The driving shaft of the synchronous motor 5 passes through the circular receiving plate 6 and is fixedly connected to the fixed side plate 7. The top of the square receiving plate 301 is fixedly connected to the bottom of the hydraulic push rod 2.

[0031] There are two vertical sleeves 4, and the two vertical sleeves 4 are distributed at the bottom of the rectangular hanging plate 1. There are two straight electric slide rails 8, and the two straight electric slide rails 8 are distributed on one side of the fixed side plate 7. There are two multifunctional inner clamping devices 9, and the two multifunctional inner clamping devices 9 are distributed on one side of the straight electric slide rail 8.

[0032] Multiple buffer springs 302 are provided, and the multiple buffer springs 302 are distributed between the square receiving plate 301 and the square pressure plate 303. The outer side of the inner sliding block 307 is slidably connected to the inner wall of the rectangular long hole 305. The side of the small electric slide rail 308 close to the inner sliding block 307 is fixedly connected to one side of the square receiving plate 301.

[0033] The top of the square pressure plate 303 is fixedly connected to an inner support rod 309, the top of the inner support rod 309 is fixedly connected to a limited position circular block 310, and the bottom of the square receiving plate 301 is fixedly connected to a bottom ring plate 311;

[0034] The top of the inner support rod 309 passes through the square receiving plate 301 and is slidably connected to the square receiving plate 301. There are multiple inner support rods 309, and the multiple inner support rods 309 are distributed at the top of the square pressure plate 303, which is located inside the buffer spring 302. There are multiple bottom ring plates 311, and the multiple bottom ring plates 311 are distributed at the bottom of the square receiving plate 301, which is located outside the buffer spring 302. When in use, the LCD screen substrate is placed between the two multifunctional inner clamping devices 9, and the two multifunctional inner clamping devices 9 are driven by the straight electric slide rail 8 to move toward each other to adjust the LCD screen substrate. After the polarizer is fixed by the inner clamp, the polarizer is placed on the LCD screen substrate. The hydraulic push rod 2 pushes the buffer pressing device 3 downward to perform a double patch process of pressing and rolling on the polarizer. After the polarizer is pasted, the hydraulic push rod 2 drives the buffering patch device to move back a distance upward, and then the synchronous motor 5 is started to drive the straight electric slide 8 through the fixed side plate 7 to turn the LCD screen substrate clamped by the multifunctional inner clamping device 9 180 degrees. Then, the polarizer is placed on the LCD screen substrate, and the hydraulic push rod 2 pushes the buffer pressing device 3 to perform patch processing on the polarizer.

[0035] The hydraulic push rod 2 pushes the square receiving plate 301 downward and drives the square pressure plate 303 at the bottom to move downward together through the buffer spring 302. The square pressure plate 303 stops moving when it moves down and contacts the polarizer. At this time, the square receiving plate 301 continues to move downward and compresses the buffer spring 302. When the buffer spring 302 is compressed, it continuously increases the thrust on the square pressure plate 303, so that the pressure of the square pressure plate 303 on the polarizer gradually increases. By arranging the buffer spring 302 between the square receiving plate 301 and the square pressure plate 303, increasing pressure is applied to the polarizer. At the same time, the inner sliding block 307 can be driven by the small electric slide rail 308 to drive the circular pressure roller 306 to roll the pressed polarizer, and the circular pressure roller 306 is used to roll the polarizer that is not completely pressed. The bottom ring plate 311 moves down and stops moving when it contacts the square pressure plate 303. At this time, the compressed buffer spring 302 is located on the inside of the bottom ring plate 311 and is always in an incompletely contracted state. By providing a bottom ring plate 311 at the bottom of the square receiving plate 301, it is convenient to accommodate the compressed buffer spring 302 so that it is always in an incompletely contracted state. After the polarizer is pasted, the square receiving plate 301 is driven upward by the hydraulic push rod 2, so that the buffer spring 302 is continuously stretched until the buffer spring 302 is fully stretched, driving the bottom square pressure plate 303 to move up together.

[0037] The spaced-type locking mechanism 907 includes an inscribed circular rod 9071, one end of which is fixedly connected to a square clamping block 9072, one side of which is provided with a circular through hole 9073, an inner smooth circular plate 9074 being slidably connected to the inner wall of the circular through hole 9073, one side of which is fixedly connected to a rounded sleeve block 9075, an inner side of which is fixedly connected to a rounded plastic pad 9076, a side of the inner smooth circular plate 9074 away from the rounded sleeve block 9075 is fixedly connected to a push spring 9077, a side of the inner smooth circular plate 9074 close to the push spring 9077 is fixedly connected to a circular sleeve shell 9078, a side of the circular sleeve shell 9078 is penetrated and slidably connected to a T-shaped circular rod 9079, and the inscribed circular rod 90 The end of 9071 away from the square block 9072 is fixedly connected to the inner side of the concave vent shell 906, the end of the push spring 9077 away from the inner smooth circular plate 9074 is fixedly connected to the inner side of the concave vent shell 906, the end of the T-shaped round rod 9079 away from the circular sleeve 9078 is fixedly connected to the inner side of the concave vent shell 906, the circular through hole 9073 passes through the square block 9072 and extends to the end of the inscribed round rod 9071 away from the square block 9072. When in use, the LCD screen substrate is placed between the two concave vent shells 906 and on the correction clamping rod 911 at the bottom of the side angle block 910. At this time, the two concave vent shells 906 are driven to move toward each other by the straight electric slide rail 8, and the concave vent shells 906 move, driving the spaced-type clamping inside. The mechanism 907 moves together until the spaced-type locking mechanism 907 stops when it is in close contact with the LCD screen substrate. At this time, the LCD screen substrate is clamped and fixed. The two concave vent shells 906 move toward each other to fix the LCD screen substrate in an internal clamping manner. When the concave vent shell 906 approaches the LCD screen substrate, the high-pressure air pump 902 draws gas into the square vent shell. The gas passes through the vent pipe 905 from the square vent shell and enters the concave vent shell 906. When the gas fills the inside of the concave vent shell 906, it is ejected outward through the air jet hole 908. By opening a plurality of air jet holes 908 on the inside of the concave vent shell 906, dust is blown off the surface of the LCD screen substrate. The gas ejected from the air jet hole 908 and the concave arc plate 90 29 contacts and flows along the arc path of the concave arc plate 9029 toward the LCD screen. The concave arc plate 9029 is provided on the inner side of the concave vent shell 906 to guide the ejected gas. A correction block is provided on one side of the concave vent shell 906 to correct the parallel height position of the LCD screen substrate. When the concave vent shell 906 moves toward the LCD screen substrate, it drives the inner inscribed circular rod 9071 and the square block 9072 to move together. When the LCD screen substrate gradually approaches the square block 9072, it contacts the circular plastic pad 9076 and pushes the rounded sleeve block 9075 to move into the circular through hole 9073 until the side of the LCD screen substrate is in tight contact with the circular plastic pad 9076 and the square block 9072 at the same time.At this point, the LCD screen substrate is secured by the inner clamp. A circular plastic pad 9076 is positioned on one side of the square clamp 9072 to press against the side of the LCD screen substrate, increasing static friction. A rounded corner sleeve 9075 is sleeved around the outer side of the circular plastic pad 9076 to facilitate sliding contact with the LCD screen substrate. A push spring 9077 is positioned on one side of the inner sliding circular plate 9074 to ensure that the circular plastic pad 9076 is constantly in press contact with the side of the LCD screen substrate. A circular sleeve 9078 is sleeved around the T-shaped round rod 9079 to limit the maximum outward movement of the rounded corner sleeve 9075.

[0038] When the present invention is in operation, the LCD screen substrate is placed between the two multifunctional inner clamping devices 9, and the two multifunctional inner clamping devices 9 are driven by the straight electric slide 8 to move toward each other to fix the LCD screen substrate. Then, the polarizer is placed on the LCD screen substrate, and the buffered pressing device 3 is pushed downward by the hydraulic push rod 2 to perform a dual patch processing of pressing and rolling on the polarizer. After the polarizer is patched, the buffered patch device is driven upward by the hydraulic push rod 2 for a distance, and then the synchronous motor 5 is started to drive the LCD screen substrate clamped by the multifunctional inner clamping device 9 on the inner side of the straight electric slide 8 through the fixed side plate 7 to flip 180 degrees. Then, the polarizer is placed above the LCD screen substrate, and the buffered pressing device 3 is pushed by the hydraulic push rod 2 to perform patch processing on the polarizer.

[0039] The hydraulic push rod 2 pushes the square receiving plate 301 to move downward and drives the square pressure plate 303 at the bottom to move downward together through the buffer spring 302. The square pressure plate 303 stops moving when it moves down and contacts the polarizer. At this time, the square receiving plate 301 continues to move downward and compresses the buffer spring 302. When the buffer spring 302 is compressed, it continuously increases the thrust on the square pressure plate 303, so that the pressure of the square pressure plate 303 on the polarizer gradually increases. By arranging the buffer spring 302 between the square receiving plate 301 and the square pressure plate 303, increasing pressure is applied to the polarizer. At the same time, the inner sliding block 307 can be driven by the small electric slide rail 308 to drive the circular pressure roller 306 to roll the pressed polarizer. 06 The polarizer that has not been fully pressed is subjected to roller coating treatment. An inner supporting rod 309 is provided inside the buffer spring 302 to internally support and stabilize the buffer spring 302. When the square receiving plate 301 continues to move downward, it drives the bottom ring plate 311 to move downward together. The bottom ring plate 311 stops moving when it moves down to contact with the square pressing plate 303. At this time, the compressed buffer spring 302 is located inside the bottom ring plate 311 and is always in an incompletely contracted state. By providing a bottom ring plate 311 at the bottom of the square receiving plate 301, it is convenient to accommodate the compressed buffer spring 302 so that it is always in an incompletely contracted state. After the polarizer is attached, the square receiving plate 301 is driven upward by the hydraulic push rod 2, so that the buffer spring 302 The buffer spring 302 is continuously extended until it is fully extended, driving the bottom square pressure plate 303 to move upward, placing the LCD screen substrate between the two concave vent shells 906 and on the correction clamping rod 911 at the bottom of the side angle block 910. At this time, the two concave vent shells 906 are driven to move toward each other by the straight electric slide rail 8. When the concave vent shells 906 move, the inner spaced-type clamping mechanism 907 is driven to move together until the spaced-type clamping mechanism 907 is in close contact with the LCD screen substrate. At this time, the LCD screen substrate is clamped and fixed. The LCD screen substrate is fixed by the inner clamping method by moving the two concave vent shells 906 toward each other. When the concave vent shells 906 are close to the LCD screen substrate, the high-pressure air pump is used to press the concave vent shells 906 into the inner spaced-type clamping mechanism 907. 902 draws gas into the square vent shell, and the gas passes through the vent pipe 905 from the square vent shell into the concave vent shell 906. When the gas fills the concave vent shell 906, it is ejected outward through the air jet hole 908. By opening multiple air jet holes 908 on the inner side of the concave vent shell 906, dust is blown off the surface of the LCD screen substrate. The gas ejected from the air jet hole 908 contacts the concave arc plate 9029 and flows along the arc path of the concave arc plate 9029 toward the LCD screen. The ejected gas is guided by setting a concave arc plate 9029 on the inner side of the concave vent shell 906. A correction block is set on one side of the concave vent shell 906 to correct the height parallelism of the LCD screen substrate.When the concave vent shell 906 moves toward the LCD screen substrate, it drives the inner circular rod 9071 and the square clamp 9072 to move together. When the LCD screen substrate gradually approaches the square clamp 9072, it contacts the circular plastic pad 9076 and pushes the rounded sleeve 9075 to move into the circular through hole 9073 until the side of the LCD screen substrate is in tight contact with the circular plastic pad 9076 and the square clamp 9072 at the same time. At this time, the LCD screen substrate is fixed by the inner clamp and is fixed by the square clamp 907. A circular plastic pad 9076 is provided on one side to press against the side of the LCD screen substrate to increase static friction. A rounded corner block 9075 is installed outside the circular plastic pad 9076 to facilitate sliding contact with the LCD screen substrate. A push spring 9077 is installed on one side of the inner sliding circular plate 9074 to ensure that the circular plastic pad 9076 is constantly in press contact with the side of the LCD screen substrate. A circular sleeve 9078 is installed on the T-shaped round rod 9079 to limit the maximum outward movement distance of the rounded corner block 9075.
