Description

Technical Field

[0001] This utility model relates to the field of film-applying auxiliary fixtures, and in particular to a film-applying auxiliary fixture for backlight production. Background Technology

[0002] A backlight is a light source located behind a liquid crystal display (LCD), and its emission effect directly affects the visual effect of the LCD module. LCDs themselves do not emit light; they display graphics or are the result of their modulation of light. Widely used in touchscreens, backlights, LCD / LCMs, mobile phones, tablets, GPS devices, solar cells, and other industries, our company is a leader in the field. Our multi-machine automated film-coating production line achieves fully automated production, saving customers over 80% of production workers and significantly reducing labor costs. We provide a complete set of applicable production processes and solutions. During backlight production, a film coating process is performed, where the backlight is clamped by fixtures before the coating is applied.

[0003] For example, Chinese Patent Publication No. CN210270426U discloses an auxiliary film-applying fixture for backlight production, relating to the field of backlight production technology. The fixture includes a main body, a support rod on top of the main body, a support plate mounted on top of the support rod, a first sliding groove on the inner side of the support plate, a fixed clamping block on top of the support plate, and a movable clamping plate on one side of the fixed clamping block. This design is reasonable and easy to operate. The movable clamping plate slides between the first limiting rod and the support plate, reaching a position where it can clamp the backlight component. Sponges at both ends protect the backlight component and prevent pressure from excessively stiff clamps during clamping.

[0004] However, in the above solution, the device clamps the backlight by bringing the two clamps close to each other. But clamping the backlight with only two clamps cannot quickly position the backlight, causing the backlight to be out of the center of the clamp. As a result, when applying film to multiple backlights, the position of each backlight is different, which can easily affect the film application efficiency. Utility Model Content

[0005] This invention provides a film-applying auxiliary fixture for backlight production to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A backlight production film-applying auxiliary fixture includes a worktable. The top of the worktable has a cleaning structure. A clamping groove is formed on the top of the worktable. Four through-type sliding grooves are formed at the bottom of the clamping groove. The four sliding grooves are symmetrically arranged front-back and left-right. A sliding rod is fixedly connected to each of the four sliding grooves. A sliding block is slidably connected to the outer sidewall of each of the four sliding rods. The four sliding blocks are slidably connected to the four sliding grooves respectively. A second clamping plate is fixedly connected to the top of the left and right sliding blocks. A sliding groove is formed on the top of the front and rear sliding blocks. Two guide rods are fixedly connected to each of the two sliding grooves. A connecting plate is slidably connected to the outer sidewall of the two guide rods in the two sliding grooves. The two connecting plates are slidably connected to the two sliding grooves respectively. Springs are fixedly connected to the sidewalls of the two connecting plates. One end of each spring is fixedly connected to the sidewall of the two sliding grooves respectively. A first clamping plate is fixedly connected to the top of each connecting plate.

[0008] The bottom of the workbench is rotatably connected to a second screw, the bottom of which is fixedly connected to a turntable. A connecting block is threaded onto the outer ring sidewall of the second screw. Connecting rods are rotatably connected to all four sides of the connecting block via rotating shafts. One end of each of the four connecting rods is rotatably connected to the bottom sidewall of four sliding blocks via rotating shafts.

[0009] As a further improvement to this technical solution: the cleaning structure includes two side plates, both of which are fixedly connected to the top side wall of the workbench. The two side plates are located on both sides of the clamping groove. A limit rod is fixedly connected between the two side plates. A sliding plate is slidably connected to the outer side wall of the limit rod. A first screw is rotatably connected to the side wall of one of the side plates. One end of the first screw passes through the sliding plate and is threadedly connected to the sliding plate. Another end of the first screw passes through the other side plate and is rotatably connected to the side plate. A motor is fixedly connected to the top of the workbench. One end of the first screw is fixedly connected to the output shaft of the motor. A cleaning plate is provided at the bottom of the sliding plate.

[0010] As a further improvement to this technical solution: a cleaning roller is rotatably connected to the bottom of the sliding plate, and an adhesive film roll is provided on the surface of the cleaning roller.

[0011] As a further improvement to this technical solution: rubber pads are provided on the side walls of the two first clamping plates and the two second clamping plates to protect the backlight and prevent the two first clamping plates and the two second clamping plates from scratching the surface of the backlight.

[0012] As a further improvement to this technical solution: both springs are made of stainless steel, which can increase the strength and service life of the two springs.

[0013] As a further improvement to this technical solution: four support rods are fixedly connected to the bottom of the workbench.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. When it is necessary to clamp and fix the backlight, place the backlight in the clamping groove, and then rotate the turntable. The turntable drives the second screw to rotate. When the second screw rotates, it can drive the connecting block to move. The connecting block can simultaneously pull the four sliding blocks to move through the four connecting rods. The four sliding blocks simultaneously drive the two second clamping plates and the two first clamping plates to move closer to each other, thereby clamping and fixing the backlight. By rotating the second screw, the two first clamping plates and the two second clamping plates can clamp the backlight at the same time. By moving the two first clamping plates and the two second clamping plates at the same time, the backlight can be kept in the center of the clamping groove, which facilitates the quick positioning of the backlight.

[0016] 2. When clamping backlights of different sizes, because the sliding grooves at the bottom of the two first clamping plates are shorter than those at the bottom of the two second clamping plates, the two first clamping plates will contact the backlights first. When the two first clamping plates contact the backlights, they drive the two connecting plates to slide in the sliding grooves. At the same time, the connecting plates compress the springs. Under the action of the springs, the two first clamping plates can always be pressed against the side walls of the backlights until the two second clamping plates are pressed against the side walls of the backlights, thereby clamping and fixing backlights of different sizes. At the same time, when the two first clamping plates and the two second clamping plates move simultaneously, the backlights can be kept in the center of the clamping grooves, which facilitates the quick positioning of backlights of different sizes.

Two guide rods 22 are fixedly connected in each of the two sliding grooves 21. The outer sidewalls of the two guide rods 22 in the two sliding grooves 21 are slidably connected to a connecting plate 20. The two connecting plates 20 are slidably connected in the two sliding grooves 21 respectively. Springs 23 are fixedly connected to the sidewalls of the two connecting plates 20 respectively. One end of each spring 23 is fixedly connected to the sidewall of the two sliding grooves 21. The top of each connecting plate 20 is fixedly connected to a first clamping plate 5.

[0030] The bottom of the workbench 1 is rotatably connected to a second screw 12, the bottom of the second screw 12 is fixedly connected to a turntable 13, the outer ring side wall of the second screw 12 is threaded with a connecting block 17, and the four connecting blocks 17 are rotatably connected to connecting rods 18 through a rotating shaft. One end of each of the four connecting rods 18 is rotatably connected to the bottom side wall of the four sliding blocks 16 through a rotating shaft.

[0031] Please see Figure 1 , Figure 3 The cleaning structure includes two side plates 2, both of which are fixedly connected to the top side wall of the workbench 1. The two side plates 2 are located on both sides of the clamping groove 4. A limit rod 3 is fixedly connected between the two side plates 2. A sliding plate 7 is slidably connected to the outer side wall of the limit rod 3. A first screw 11 is rotatably connected to the side wall of one of the side plates 2. One end of the first screw 11 passes through the sliding plate 7 and is threadedly connected to the sliding plate 7. The other end of the first screw 11 passes through the other side plate 2 and is rotatably connected to the side plate 2. A motor 8 is fixedly connected to the top of the workbench 1. One end is fixedly connected to the output shaft of the motor 8. The bottom of the sliding plate 7 is provided with a cleaning plate 9. The bottom of the sliding plate 7 is rotatably connected to a cleaning roller 19. The surface of the cleaning roller 19 is provided with an adhesive film roll. When the motor 8 is started, the output shaft of the motor 8 drives the first screw 11 to rotate. When the first screw 11 rotates, it can drive the sliding plate 7 to move. The sliding plate 7 simultaneously drives the cleaning plate 9 and the cleaning roller 19 to move. The cleaning plate 9 can perform preliminary cleaning on the surface of the backlight, and the cleaning roller 19 can perform secondary adhesion cleaning on the surface of the backlight, thereby facilitating the improvement of the subsequent film application effect.

[0032] Please see Figure 1 , Figure 3-5The two first clamping plates 5 and the two second clamping plates 6 are all equipped with rubber pads on their side walls, which can protect the backlight and prevent the two first clamping plates 5 and the two second clamping plates 6 from scratching the surface of the backlight.

[0033] Please see Figure 4-5 Both springs 23 are made of stainless steel, which increases their strength and service life.

[0034] The working principle of this utility model is as follows: When it is necessary to clamp and fix the backlight, the backlight is placed in the clamping groove 4, and then the turntable 13 is rotated. The turntable 13 drives the second screw 12 to rotate. When the second screw 12 rotates, it can drive the connecting block 17 to move. The connecting block 17 can simultaneously pull the four sliding blocks 16 to move through the four connecting rods 18. The four sliding blocks 16 simultaneously drive the two second clamping plates 6 and the two first clamping plates 5 to move closer to each other, thereby clamping and fixing the backlight. By rotating the second screw 12, the two first clamping plates 5 and the two second clamping plates 6 can be driven to clamp the backlight at the same time. By moving the two first clamping plates 5 and the two second clamping plates 6 at the same time, the backlight can be kept in the center of the clamping groove 4, which facilitates the rapid positioning of the backlight.

[0035] When clamping backlights of different sizes, because the sliding grooves 10 at the bottom of the two first clamping plates 5 are shorter than the sliding grooves 10 at the bottom of the two second clamping plates 6, the two first clamping plates 5 will contact the backlights first. When the two first clamping plates 5 contact the backlights, the two first clamping plates 5 drive the two connecting plates 20 to slide in the sliding groove 21. At the same time, the connecting plates 20 compress the spring 23. Under the action of the spring 23, the two first clamping plates 5 can always be pressed against the side wall of the backlight until the two second clamping plates 6 are pressed against the side wall of the backlight, thereby clamping and fixing backlights of different sizes. At the same time, when the two first clamping plates 5 and the two second clamping plates 6 move at the same time, the backlight can be kept in the center of the clamping groove 4, which makes it easy to quickly position backlights of different sizes.

[0036] By starting the motor 8, the output shaft of the motor 8 drives the first screw 11 to rotate. When the first screw 11 rotates, it can drive the sliding plate 7 to move. The sliding plate 7 simultaneously drives the cleaning plate 9 and the cleaning roller 19 to move. The cleaning plate 9 can perform preliminary cleaning on the backlight surface, and the cleaning roller 19 can perform secondary adhesion cleaning on the backlight surface, thereby facilitating the improvement of the subsequent film application effect.
