[0024] A fixing device for LCD production, comprising a substrate 1. On the top of the substrate 1, symmetrically arranged sliding seats 3 are slidably mounted. On the outer wall of the top of the substrate 1, symmetrically arranged movable grooves 2 are provided. The two sliding seats 3 are respectively slidably arranged on the inner walls of the two movable grooves 2. On the top of the two sliding seats 3, placing seats 4 are fixedly mounted. On the top of the two placing seats 4, placing grooves 5 are provided. On the outer wall of the top of the substrate 1, a guiding track 12 is fixedly mounted. A guiding block 14 is slidably arranged in the inner wall of the guiding track 12. On the outer walls of both sides of the guiding block 14, symmetrically arranged connecting frames 16 are fixedly connected. On the two connecting frames 16, guiding rods 13 are hingedly arranged. On the outer walls of the opposite sides of the two sliding seats 3, guiding brackets 15 are fixedly connected. One ends of the two guiding rods 13 are respectively hingedly arranged on the two guiding brackets 15. On the right side of the top of the substrate 1, a fixing plate 6 is fixedly arranged. On the left outer wall of the fixing plate 6, a lead screw 17 is rotatably mounted. A threaded hole is provided on the guiding block 14, and the lead screw 17 is screwed on the inner wall of the threaded hole. On the left outer wall of the guiding track 12, a mounting plate 18 is fixedly connected. On the outer wall of one side of the mounting plate 18, a driving motor 19 is fixedly mounted. The output shaft of the driving motor 19 is connected to the end of the lead screw 17. Starting the driving motor 19 drives the lead screw 17 to rotate. The lead screw 17 cooperates with the arranged guiding track 12 to drive the guiding block 14 to move horizontally. The guiding block 14 drives the two connecting frames 16 to move horizontally. The two connecting frames 16 cooperate with the two arranged guiding brackets 15 to change the inclination angles of the two guiding rods 13. When the inclination angles of the two guiding rods 13 change, the two arranged guiding brackets 15 can drive the two sliding seats 3 to move in opposite or relative directions, so that the two sliding seats 3 can drive the two placing seats 4 to move in opposite or relative directions, achieving the effect of adjusting the distance between the two placing seats 4, facilitating the placement of LCDs of different sizes in the placing grooves 5 provided on the two placing seats 4. When the distance between the two placing seats 4 is adjusted, the two ends of the LCD to be processed are respectively placed on the two placing grooves 5, so that the two ends of the LCD abut against the inner walls of the two placing grooves 5.

[0025] In a specific embodiment, a support plate 7 is fixedly arranged on the outer wall of the top of the fixed plate 6. A support rod 11 with an L-shaped structure is fixedly connected to the outer wall of the left side of the substrate 1. The support rod 11 is fixedly connected to the outer wall of the bottom of the support plate 7. A support seat 8 is fixedly installed on the outer wall of the top of the support plate 7. A chute is formed in the top of the support seat 8, and a support block 22 is slidably arranged on the inner wall of the chute. A limit seat 9 is fixedly installed on the outer wall of the top of the support block 22. A rubber pad 10 is fixedly connected to the outer wall of one side of the limit seat 9. A fixed seat 20 is fixedly arranged on the outer wall of the top of the support plate 7. A cylinder 21 is fixedly installed on the outer wall of one side of the fixed seat 20. The piston rod of the cylinder 21 is connected to the outer wall of one side of the support block 22. After the LCD is placed, the cylinder 21 is started to work. With the cooperation of the provided support seat 8, the cylinder 21 drives the support block 22 to move horizontally. The support block 22 drives the limit seat 9 to move towards the side close to the LCD until the rubber pad 10 installed on one side of the limit seat 9 contacts the side wall of the LCD, so as to be able to position the LCD and achieve the fixing effect on the LCD.

[0026] The implementation principle of a fixing device for LCD production in this embodiment is as follows:

[0027] When it is necessary to fix the LCD, the driving motor 19 is started to drive the lead screw 17 to rotate. The lead screw 17 drives the guide block 14 to move horizontally with the cooperation of the provided guide rail 12. The guide block 14 drives the two connecting frames 16 to move horizontally. The two connecting frames 16 change the inclination angles of the two guide rods 13 with the cooperation of the two guide brackets 15. When the inclination angles of the two guide rods 13 change, the two guide brackets 15 can drive the two sliding seats 3 to move in opposite or relative directions, so that the two sliding seats 3 can drive the two placing seats 4 to move in opposite or relative directions, achieving the effect of adjusting the distance between the two placing seats 4, which is convenient for placing LCDs of different sizes in the placing grooves 5 formed in the two placing seats 4. After the distance between the two placing seats 4 is adjusted, the two ends of the LCD to be processed are respectively placed on the two placing grooves 5, so that the two ends of the LCD abut against the inner walls of the two placing grooves 5. After the LCD is placed, the cylinder 21 is started to work. With the cooperation of the provided support seat 8, the cylinder 21 drives the support block 22 to move horizontally. The support block 22 drives the limit seat 9 to move towards the side close to the LCD until the rubber pad 10 installed on one side of the limit seat 9 contacts the side wall of the LCD, so as to be able to position the LCD and achieve the fixing effect on the LCD.
