Description

Light guide plate cutting machine

technical field

The invention relates to a light guide plate cutting machine.

Background technique

Since the light guide plate is similar to an acrylic plate, there are many ways to cut the light guide plate, including laser or direct cutting, but the current relatively low-cost or relatively simple cutting method is to draw a line on the light guide plate, and then press on both sides. Disconnect the light guide plate like scratching glass.

However, because this method is extended from the traditional light guide plate, there are many kinds of light guide plate with its own development, such as the light guide plate with many bumps and pits on the surface, so it can be done with ordinary scratches. When scribing, the pits cannot be effectively scribbled, resulting in uneven cross-sections or roughness when the light guide plate is opened.

Detailed ways

The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, and the implementation scope of the present invention is not limited thereto.

As shown in Figures 1 to 5, a light guide plate cutting machine described in this embodiment, a light guide plate cutting machine, a light guide plate cutting machine, includes a shelving platform b11 for placing the light guide plate, and the shelving platform b11- The side is provided with a push plate b12 and a push cylinder that drives the push plate b12 forward; it also includes a first press cylinder b21, and the power output end of the first press cylinder b21 is connected with a cutting head for marking the light guide plate b5; also includes a track b41 horizontally arranged on the resting platform b11, the first press-down cylinder b21 is slidably connected with the track b41; also includes a track b41 that can make the first press-down cylinder b21 reciprocate on the track b41 Cylinder; the other side of the laying platform b11 is provided with a first pressing plate b31 with an L-shaped cross section and a second pressing cylinder b22 that pushes the first pressing plate b31 down; the first pressing plate b31 is far away from one side of the laying platform b11 A second pressing plate b32 with an L-shaped cross section and a third pressing cylinder b23 for pushing down the second pressing plate b32 are also provided on the side. The track b41 is two cylindrical rods.

The cutting head b5 includes three main cutting heads a11, and the bottom of each main cutting head a11 is provided with a wedge-shaped main blade a12;

A connecting rod a31 is provided between two adjacent main cutter heads a11, and a convex corrugation a34 is arranged on the opposite side between two adjacent main cutter heads a11, and a slide is provided between two adjacent main cutter heads a11. Block a32, the two sides of slide block a32 are provided with the first guide groove that cooperates with convex a34; Also include screw rod a33, the bottom of described screw rod a33 is connected with the top of slide block a32, screw rod a33 passes connecting rod a31, the top Screwed with adjusting nut;

An auxiliary cutter head a21 is provided between two adjacent main cutter heads a11, and the bottom of the auxiliary cutter head a21 is provided with a wedge-shaped auxiliary blade a22, and the main viewing surface of the auxiliary blade a22 is an acute triangle; Both sides are provided with a second guide groove that can cooperate with the convex corrugation a34, and the auxiliary cutter head a21 can move up and down along the convex corrugation a34; a compression spring a35 is connected between the top of the auxiliary cutter head a21 and the bottom of the connecting rod a31.

The specific principle is shown in Figure 5. The light guide plate of the present invention is placed on the light guide plate resting platform b11, and the push plate b12 is pushed forward to push the light guide plate to a predetermined position. The second pressing cylinder b22 presses down the first pressure plate b31 and fixes it For the light guide plate, the first pressing cylinder b21 presses down to press the cutting head b5 on the light guide plate, and then the first pressing cylinder b21 reciprocates once on the track b41 to draw a track shape on the light guide plate. Then, the second pressing cylinder b22 lifts up the first pressing plate b31. After being lifted up, the pushing plate b12 pushes the line of the light guide plate to the edge of the resting platform b11, or the outside of the resting platform b11, and then the second pressing down cylinder b22 The first pressing plate b31 is pressed down to fix the light guide plate.
