Description

Technical Field

[0001] This utility model relates to a quantum dot film material processing device, specifically a quantum dot liquid crystal material processing device. Background Technology

[0002] Quantum dot films, as a novel nanomaterial with unique optical properties, can precisely and efficiently convert high-energy blue light into red and green light. Quantum dots can be formed into a thin film on the LED backlight of LCD displays, emitting full-spectrum light when illuminated by blue LEDs. By finely adjusting the backlight, color gamut performance can be significantly improved, making colors more vivid. The processing of quantum dot film materials typically requires cutting.

[0003] In the prior art, a utility model patent with patent number "CN 217122134 U" discloses a cutting device for quantum dot films, including a transmission frame, a cutting frame, and a moving plate. The transmission frame contains two rollers rotatably connected to it via rotating rods. The two rollers are connected by a transmission belt. A motor is fixedly connected to the right end of the rear surface of the transmission frame, and the motor output is fixedly connected to a rotating rod at one end of each roller via a rotating shaft. A cutting plate is fixedly connected to the upper surface of the transmission belt. Limiting frames are fixedly connected to both ends of the upper surface of the cutting plate. A pull rod is provided at the upper end of the limiting frame, penetrating the limit frame and slidably connected to the penetrating portion. A pressure plate is fixedly connected to the lower end of the pull rod. Airbags are fixedly connected to both ends of the lower surface of the pressure plate. Springs are provided on the surface of the pull rod, with each end fixedly connected to the limiting frame and the pressure plate respectively. This utility model provides a cutting device for quantum dot films, which can improve the cutting efficiency of quantum dot films, thereby improving work efficiency.

[0004] However, in the aforementioned patent, both levers need to be pulled up simultaneously before the quantum dot film can be placed. Since the two levers are set up independently, each lever needs to be pulled up with two hands. Therefore, placing the quantum dot film requires another person, and thus requires two people to work together to place the quantum dot film on the cutting board. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] A quantum dot liquid crystal material processing apparatus includes a conveyor 1, a cutting mechanism 3 above the conveyor 1, and cutting seats 2 spaced apart along the conveying direction on the conveying section of the conveyor 1. An infrared sensor is provided on one side of the conveyor 1, located below the cutting mechanism 3 and corresponding to the cutting seats 2. The quantum dot liquid crystal film is placed on the cutting seats 2 and fixed, and then conveyed on the conveyor 1 to the area below the cutting mechanism 3. When the infrared sensor detects that a cutting seat 2 has been conveyed to the area below the cutting mechanism 3, the conveyor 1 stops conveying, and the cutting mechanism 3 performs the cutting.

[0023] The cutting seat 2 includes a base plate 15 fixedly mounted on the conveyor 1. Support portions 16 extend upwards from both sides of the base plate 15. The line connecting the two sides of the base plate 15 is perpendicular to the conveying direction of the conveyor 1. Limiting frames 17 extend inwards from the upper ends of the two support portions 16, but are not connected, with a large gap between them to facilitate the placement of the quantum dot liquid crystal film. A vertical pull rod 18 slides vertically on each limiting frame 17, and a guide hole extends vertically through each limiting frame 17. The guide hole matches the pull rod 18, and the pull rod 18 passes through the guide hole. The lower end of the pull rod 18 is fixedly provided with a pressure plate 19, which is located below the limiting frame 17. A spring is sleeved on the pull rod 18, and the two ends of the spring are respectively connected to the pressure plate 19 and the limiting frame 17. The spring has a vertical elastic force. When the quantum dot liquid crystal film is placed on the substrate 15, the pressure plate 19 is pushed downward under the action of the spring force, pressing on the quantum dot liquid crystal film to press and fix it.

[0024] The upper end of the pull rod 18 passes through the limiting frame 17 and is fixedly equipped with a connecting frame 8. The connecting frame 8 is located above the limiting frame 17. A cam 5 is symmetrically provided on each of the two outer walls of the base plate 15. The cam 5 is sideways. A rotating transmission rod 4 passes through the base plate 15. Both cams 5 are fixedly installed on the transmission rod 4. One end of the transmission rod 4 is connected to a handle 9. The two cams 5 are respectively connected to the two connecting frames 8 through a lifting frame. Shaking the handle 9 drives the transmission rod 4 to rotate, so that the two cams 5 on the transmission rod 4 rotate synchronously. Then, the lifting frame pushes the connecting frame 8 to move vertically, thereby pulling up the pull rod 18.

[0025] With this invention, when fixing the quantum dot liquid crystal film on the cutting seat 2, only one hand needs to turn the handle 9 to simultaneously pull up the two levers 18, and the other hand can place the quantum dot liquid crystal film on the substrate 15, and then lower the two levers 18 to press the quantum dot liquid crystal film. Only one person is needed to operate it. The structure is simple and easy to operate.

[0026] In a preferred embodiment, the lifting frame includes a guide sleeve 6 fixedly mounted on the outer wall of the support portion 16. The guide sleeve 6 is vertically positioned, and a vertical guide rod 7 is slidably mounted inside the guide sleeve 6. The upper end of the guide rod 7 is fixedly connected to the connecting frame 8, and the lower end of the guide rod 7 is slidably mounted against a cam 5. When the cam 5 rotates, it can push the guide rod 7 vertically, thereby driving the connecting frame 8 to move vertically and pulling up the pull rod 18.

[0027] In a preferred embodiment, the lower surface of the pressure plate 19 is provided with an air cushion 20. The air cushion 20 achieves soft contact with the quantum dot liquid crystal film.

[0028] In a preferred embodiment, the cutting mechanism 3 includes a bracket 21 and a laser cutting blade 14. The laser cutting blade 14 is oriented in the same direction as the cutting seat 2. The laser cutting blade 14 is mounted on the bracket 21 via a transverse moving mechanism and a longitudinal moving mechanism. The bracket 21 is mounted on the frame of the conveyor 1.

[0029] In a preferred embodiment, the longitudinal moving mechanism includes a longitudinal guide rail 22 fixed on the bracket 21. The length direction of the longitudinal guide rail 22 is perpendicular to the conveying direction of the conveyor 1. A first slide block 10 is slidably mounted on the longitudinal guide rail 22. The first slide block 10 is driven to move by a first lead screw. One end of the first lead screw is connected to a first motor 23. The transverse moving mechanism is mounted on the first slide block 10.

[0030] In a preferred embodiment, the transverse moving mechanism includes a transverse guide rail 11 disposed on a first slide block 10, the transverse guide rail 11 being disposed perpendicular to the longitudinal guide rail 22, a second slide block 12 being slidably disposed on the transverse guide rail 11, the second slide block 12 being driven to move by a second lead screw, one end of the second lead screw being connected to a second motor 13, and the laser cutting blade 14 being disposed on the second slide block 12.
