[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. The automatic dispensing machine for LCD screen packaging of this utility model, when the width of the LCD screen is greater than the width of the placement plate, only needs to rotate the first rocker wheel to adjust the distance between the two first movable plates. The first rocker wheel drives the worm gear to rotate through the rotating rod. The worm gear drives the worm wheel that meshes with it to rotate. The worm wheel drives the bidirectional screw to rotate. The bidirectional screw rotates in the inner cavity of the two first screw holes. The two first movable plates move towards the placement plate in the direction of the bidirectional screw on the thread. The first movable plate moves to the outer edge of the first limiting plate. The first movable plate drives the second movable plate to move to fit against the side wall of the LCD screen, thereby clamping and fixing the LCD screen.
[0014] 2. This utility model relates to an automatic dispensing machine for LCD screen packaging. When the width of the LCD screen is less than the width of the placement plate, the first rocker wheel is rotated to move the first movable plate to be in contact with the side wall of the placement plate. Then, the second rocker wheel is rotated to adjust the position of the second movable plate. The second rocker wheel drives the lead screw to rotate in the inner cavity of the second screw hole. The lead screw drives the second movable plate to move until the second movable plate is in contact with the side wall of the LCD screen, thereby clamping and fixing the LCD screen. This solves the problem that existing dispensing machines do not have a fixing mechanism, and different fixing mechanisms need to be replaced for different sizes of LCD screens. This can easily lead to excessive dispensing point errors, increase the difficulty of dispensing operations, reduce work efficiency, and cause inconvenience to users.

The support columns 2 are fixedly connected to the top of the worktable 1. A control box 5 is provided on the side wall of the support column 2. A placement plate 6 is fixedly connected to the top of the worktable 1 near the center. A worm gear 8 is provided inside the placement plate 6. A bidirectional screw 9 is fixedly passed through the inner cavity of the worm gear 8. Two fixing plates 10 are fixedly connected to the top of the inner cavity of the placement plate 6. The two ends of the bidirectional screw 9 pass through the adjacent fixing plates 10. First movable plates 7 are provided on both the left and right sides of the placement plate 6. The first limiting plate 19 is fixedly connected to both the left and right sides of the placement plate 6. The side of the first limiting plate 19 away from the placement plate 6 moves through the adjacent first movable plate 7. The first movable plate 7 has a first screw hole 11. The two ends of the bidirectional screw 9 pass through the adjacent first screw hole 11. The bidirectional screw 9 and the first screw hole 11 are threadedly connected. The bidirectional screw 9 and the fixed plate 10 are rotatably connected. The top of the worm gear 8 is provided with a worm 12 that meshes with it. The inner cavity of the worm 12 is fixedly connected with a rotating rod 13. The two ends of the rotating rod 13 pass through the front and rear sides of the placement plate 6. The rotating rod 13 and the placement plate 6 are rotatably connected. The cross-section of the placement plate 6 is U-shaped with the U-shaped opening facing down. The front end of the rotating rod 13 is fixedly connected to a first rocker wheel 14.
[0024] A second movable plate 15 is provided on the side of the first movable plate 7 near the center of the placement plate 6. A bearing is fixedly connected to the side of the second movable plate 15 away from the center of the placement plate 6. A lead screw 16 is fixedly inserted into the inner cavity of the bearing. A second screw hole 17 is provided on the first movable plate 7 near the top. The lead screw 16 passes through the adjacent second screw hole 17 and is fixedly connected to a second rocker wheel 18. The lead screw 16 and the second screw hole 17 are connected by a thread. A second limiting plate 20 is fixedly connected to the side of the second movable plate 15 away from the center of the placement plate 6. The side of the second limiting plate 20 away from the second movable plate 15 moves through the first movable plate 7.
[0025] Working principle: The automatic dispensing machine for LCD screen packaging of this utility model, during use, places the LCD screen on top of the placement plate 6. When the width of the LCD screen is greater than the width of the placement plate 6, simply rotate the first rocker wheel 14 to adjust the distance between the two first movable plates 7. The first rocker wheel 14 drives the worm gear 12 to rotate through the rotating rod 13. The worm gear 12 drives the worm wheel 8 that meshes with it to rotate. The worm wheel 8 drives the bidirectional screw 9 to rotate. The bidirectional screw 9 rotates in the inner cavity of the two first screw holes 11. The two first movable plates 7 move towards the placement plate 6 in the direction of the bidirectional screw 9 on the thread. The first movable plates 7 move on the outer edge of the first limiting plate 19. The first movable plates 7 drive the second movable plate 15 to move to fit against the side wall of the LCD screen, thereby clamping and fixing the LCD screen.
[0026] When the width of the LCD screen is less than the width of the placement plate 6, first rotate the first rocker wheel 14 to move the first movable plate 7 to be in contact with the side wall of the placement plate 6. Then rotate the second rocker wheel 18 to adjust the position of the second movable plate 15. The second rocker wheel 18 drives the lead screw 16 to rotate in the inner cavity of the second screw hole 17. The lead screw 16 moves relative to the second screw hole 17 towards the LCD screen. The lead screw 16 drives the second movable plate 15 to move. The second movable plate 15 moves within a limited trajectory set by the second limiting plate 20 until the second movable plate 15 moves to be in contact with the side wall of the LCD screen, thereby clamping and fixing the LCD screen. This solves the problem that existing dispensing machines do not have a fixing mechanism. Under the requirements of different sized LCD screens, different fixing mechanisms need to be replaced, which easily leads to excessive dispensing point errors, increases the difficulty of dispensing operation, reduces work efficiency, and causes inconvenience to users.
