Technical Field
[0001] The utility model generally relates to the field of light guide plate processing, and in particular to a light guide plate nozzle cutting device. Background Art
[0002] Light guide plates (LGPs) are a high-tech material with extremely high reflectivity and a lack of light absorption. They are manufactured from optical-grade acrylic or PC sheets and can be categorized by shape as either flat or wedge-shaped. LGPs are widely used in various electronic products. To improve efficiency and reduce costs, they are often produced using injection molding. Therefore, cutting of the semi-finished nozzle is necessary during the final processing of the finished product.
[0003] When existing nozzle cutting equipment is cutting the nozzle of a light guide plate, the light guide plate may move, causing the incision to deviate. Utility Model Content
[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desired to provide a light guide plate nozzle cutting device that prevents the light guide plate from moving during cutting.

[0006] When the pressing plate and the cutting blade are both in a suspended state, the distance between the pressing plate and the first fixing seat is smaller than the distance between the cutting blade and the first fixing seat.
[0007] According to the technical solution provided in the embodiments of the present application, the light guide plate is placed on the first fixed plate, and the driving mechanism drives the sliding seat toward the first fixed plate, allowing the cutting blade to cut the light guide plate nozzle. Before the cutting blade cuts the light guide plate nozzle, the pressing plate will press the light guide plate to prevent the light guide plate from moving during the cutting process, thereby preventing the incision from shifting.

The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0014] Please refer to Figures 1 to 3 The light guide plate nozzle cutting device of the present invention includes a first fixed plate 100, a first fixed frame 200, a first fixed seat 300, a pressing plate 400, a driving mechanism 500 and a sliding seat 600. The first fixed frame 200 is fixedly connected to the first fixed plate 100, the first fixed seat 300 is detachably fixed to the first fixed plate 100, the first fixed seat 300 is used to fix the light guide plate 700 to be processed, the sliding seat 600 is slidably connected to the first fixed frame 200, the driving mechanism 500 drives the sliding seat 600 to slide in the vertical direction, and the sliding seat 600 is detachably fixed on the side facing the first fixed seat 300. A second fixed seat 620 is fixedly connected, and a cutting knife 621 is fixedly connected to the side of the second fixed seat 620 facing the first fixed seat 300. The sliding seat 600 is fixedly connected to the second fixed plate 610. The clamping plate 400 is fixedly connected to multiple sliding rods 410. The sliding rods 410 are slidingly connected to the second fixed plate 610. The clamping plate 400 is located at the bottom of the sliding rod 410, and a limiting plate 411 is provided on the top of the sliding rod 410. When the clamping plate 400 and the cutting knife 621 are both in a suspended state, the distance between the clamping plate 400 and the first fixed seat 300 is smaller than the distance between the cutting knife 621 and the first fixed seat 300.
[0015] In an embodiment of the present invention, the first fixed frame 200 is fixedly connected to the first fixed plate 100, and the first fixed frame 200 is a gantry frame. The sliding seat 600 is slidably connected to the first fixed frame 200, and the driving mechanism 500 drives the sliding seat 600 to slide relative to the first fixed frame 200, and the sliding seat 600 slides in the vertical direction. The light guide plate 700 to be processed is fixed on the first fixed frame 300, and the driving mechanism 500 drives the sliding seat 600 to approach the first fixed frame 300, thereby driving the cutting knife 621 to cut the water outlet of the light guide plate. After cutting is completed, the driving mechanism 500 drives the sliding seat 600 away from the first fixed frame 300, and the light guide plate on the first fixed frame 300 is replaced.
[0016] The clamping plate 400 is fixedly connected to a plurality of sliding rods 410, which are slidably connected to the second fixed plate 610. The clamping plate 400 is located at the bottom of the sliding rods 410, and a limit plate 411 is provided on the top of the sliding rods 410. The limit plate 411 prevents the sliding rods 410 from separating from the second fixed plate 610. The clamping plate 400 can move with the sliding seat 600. When the driving mechanism 500 drives the sliding seat 600 toward the first fixed seat 300, the clamping plate 400 first contacts the light guide plate 700 to be processed, and the cutting blade 621 then contacts the light guide plate 700 to be processed. After the clamping plate 400 contacts the light guide plate 700 to be processed, the sliding seat 600 continues to descend. At this time, the sliding rod 410 will slide relative to the second fixed plate 610, and the limiting plate 411 will move away from the second fixed plate 610. The clamping plate 400 loses the lifting force of the second fixed plate 610. The clamping plate 400 will press the light guide plate 700 to be processed under the action of its own gravity to prevent the light guide plate from moving during the water outlet cutting process of the light guide plate, thereby preventing the incision from being offset.
