Description

Technical Field

[0001] This application relates to the field of light guide plate processing technology, specifically to a light guide plate cutting device. Background Technology

[0002] Light guide plates generally refer to high-tech sheets made of optical-grade acrylic or PC materials. To improve production efficiency and save materials, injection molding is typically used to manufacture light guide plates. Because the mold used for injection molding has multiple chambers, and there are connecting cavities between adjacent chambers, the light guide plate is still a semi-finished product after demolding and needs to be cut to remove excess material. Existing light guide plate cutting equipment generates plastic powder during the cutting process. This powder falls onto the machine, and when it accumulates significantly, it can affect production or be blown into the air by the wind, polluting the environment. Utility Model Content

[0003] To address the issue of plastic powder generation from existing light guide plate cutting devices impacting production, this application provides a light guide plate cutting device. The specific technical solution of this application is as follows:

[0004] A light guide plate cutting device includes a machine base, a transport mechanism for transporting the light guide plate, and a cutting mechanism for cutting the light guide plate, all mounted on the machine base. The cutting mechanism includes a cutting blade and a placement seat. The cutting blade is positioned above the placement seat. The device also includes a suction mechanism for absorbing powder. The suction mechanism includes a fan, a dust collection box, and an air inlet box. A through hole is provided on the machine base, located below the placement seat. The air inlet box is positioned below the through hole and connected to the air inlet of the fan to guide the airflow above the through hole into the fan. The dust collection box is connected to the air outlet of the fan to collect the powder in the airflow blown out by the fan.

[0005] Furthermore, the suction mechanism also includes an isolation block, which is disposed in the air inlet box.

[0006] Furthermore, the inner wall of the air inlet box is provided with raised strips on both sides, and the isolation block is placed on the raised strips.

[0007] Furthermore, the bottom of the dust collection box is provided with an opening, and a filter screen is provided above the opening.

[0008] Furthermore, the bottom of the dust collection box is provided with support feet.

[0009] Furthermore, the transport mechanism includes a first suction component for transporting the light guide plate to the placement stage and a second suction component for transporting the light guide plate away from the placement stage. The first suction component is movably mounted on the machine base, and the second suction component is fixedly mounted on the machine base.

[0010] Furthermore, the cutting mechanism is positioned above the through hole, and the cutting mechanism also includes a cylinder, which is vertically downward, and the cutting blade is fixedly connected to the piston rod of the cylinder.

[0011] Furthermore, the placement base is provided with a push block and a guide groove, and the push block is movably disposed in the guide groove.

[0012] Compared with existing technologies, the advantages of this application are as follows: The light guide plate cutting device described in this application is provided with a placement seat for placing the light guide plate. A through hole is provided below the placement seat, and the through hole is connected to a fan through an air inlet box. When the cutting mechanism generates plastic powder during the cutting of the light guide plate, the fan draws the plastic powder from the through hole into a dust collection box through the air inlet box, preventing the plastic powder from accumulating on the machine or drifting into the air. The fan generates downward airflow, which can cool the cutting mechanism, preventing overheating and ensuring a flat light guide plate cut by the cutting structure, thus effectively improving production quality.

[0024] The following description, in conjunction with the accompanying drawings, further illustrates specific embodiments of this application, making the technical solution and its beneficial effects clearer and more explicit. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, but should not be construed as limiting it.

[0025] like Figure 1 and Figure 6As shown, a light guide plate cutting device includes a machine base 1, a transport mechanism for transporting a light guide plate 2, and a cutting mechanism 3 for cutting the light guide plate 2, all mounted on the machine base 1. The cutting mechanism 3 includes a cutting blade 4 and a placement seat 5. The cutting blade 4 is positioned above the placement seat 5. The device also includes a suction mechanism 6 for absorbing powder. The suction mechanism 6 includes a fan 7, a dust collection box 8, and an air inlet box 9. The machine base 1 has a through hole 10 located below the placement seat 5. The air inlet box 9 is positioned below the through hole 10 and is connected to the air inlet of the fan 7 to guide the airflow above the through hole 10 into the fan 7. The dust collection box 8 is connected to the air outlet of the fan 7 to collect the powder in the airflow blown out by the fan 7. The fan 7 generates a downward airflow in the through hole 10. When the cutting mechanism 3 cuts the light guide plate 2, the plastic powder falling down and the plastic powder sticking to the light guide plate 2 will enter the fan 7 under the action of the airflow and be collected in the dust collection box 8. This can prevent the powder from accumulating on the machine 1 and also prevent the light guide plate 2 from having powder sticking to it, which would affect the subsequent processing of the light guide plate 2.

[0026] In one embodiment, the suction mechanism 6 further includes an isolation block 11, which is disposed in the air inlet box 9. The isolation block 11 can prevent large objects from being sucked into the fan 7 and affecting the operation of the fan 7.

[0027] In one embodiment, the inner wall of the air inlet box 9 is provided with protruding strips 12 on both sides, and the isolation block 11 is placed on the protruding strips 12. The isolation block 11 is placed in the air inlet box 9 to facilitate the installation and removal of the isolation block 11.

[0028] In one embodiment, the dust collection box 8 has an opening 13 at its bottom, and a filter screen 14 is disposed above the opening 13. The filter screen 14 can effectively retain plastic powder in the dust collection box 8. The opening 13 is located at the bottom of the dust collection box 8, allowing the airflow from the fan 7 to blow out from the bottom of the dust collection box 8, preventing the blown airflow from affecting the intake box 9's absorption of plastic powder.

[0029] In one embodiment, the dust collection box 8 is provided with support feet 15 at the bottom. The support feet 15 make it easier for airflow to blow out from the bottom of the dust collection box 8.

[0030] In one embodiment, the transport mechanism includes a first suction component 16 for transporting the light guide plate 2 to the placement table and a second suction component 17 for transporting the light guide plate 2 away from the placement table. The first suction component 16 is movably disposed on the machine base 1, and the second suction component 17 is fixedly disposed on the machine base 1.

[0031] In one embodiment, the cutting mechanism 3 is disposed above the through hole 10. The cutting mechanism 3 includes a cylinder 18, which is disposed vertically downwards. The cutting blade 4 is fixedly connected to the piston rod of the cylinder 18.

[0032] In one embodiment, the placement seat 5 is provided with a push block 19 and a guide groove 20, with the push block 19 movably disposed in the guide groove 20. The push block 19 can straighten the position of the light guide plate 2 on the placement seat 5, so that the cutting mechanism 3 can cut the light guide plate 2 more accurately.

[0033] The light guide plate cutting device described in this application is equipped with a placement seat 5 for placing the light guide plate 2. A through hole 10 is provided below the placement seat 5. The through hole 10 is connected to a fan 7 via an air inlet box 9. When the cutting mechanism 3 cuts the light guide plate 2 and generates plastic powder, the fan 7 draws the plastic powder from the through hole 10 into a dust collection box 8 through the air inlet box 9, preventing the plastic powder from accumulating on the machine base 1 or drifting into the air. The fan 7 generates a downward airflow, which cools the cutting mechanism 3, preventing it from overheating and ensuring the light guide plate 2 cut by the cutting mechanism is flat, thus effectively improving production quality.

[0034] In the description of this specification, the terms "in one embodiment," "preferred," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of this application.
