The light guide plate alignment process of the pneumatic impactor 1 for aligning the light guide plate having the above configuration will be described with reference to FIGS. 1 to 7.

Prior to the explanation, assuming that the pneumatic pressure is always uniform, in order to maximize the hitting force, the hitting time t should be derived to the minimum. This applies Newton's law of motion.

Strike Amount = Strike Power * Time = Movement Change

       = Mass * speed change

= f * t = m * Δv

t: time when the striking plate 450 is in contact with the light guide plate side

m: mass of the striking plate 450

v: instantaneous speed at the time of driving the blower plate 450

v ₀ : instantaneous speed of impact plate 450 hitting the light guide plate

The present invention can maximize the hitting efficiency of hitting the light guide plate (LGP) by minimizing the variable condition t (time) in order to maximize f (hit force) at f = (m * Δv) / t.

In the initial state before hitting the LGP, the switch 310 of the manual switch unit 300 maintains the state before being pressed. In the standby state before the switch 310 of the manual switch unit 300 is pressed, the pneumatic valve unit 200 maintains the first mode state.

As shown in FIG. 5A, air introduced through the external air inlet 211 in the first mode is discharged through the first air outlet 221. The air discharged through the first air outlet 221 branches in two directions via the first pneumatic branch 700, as shown in FIG. 4. Air in one direction branched from the first pneumatic branching part 700 flows into the first pneumatic inlet 420 of the striking plate part 400, and the air in the other direction is switched pneumatic supply port 330 of the manual switch part 300. Flows into) to maintain the standby state. In addition, the pneumatic pressure introduced into the first pneumatic inlet 420 of the striking plate 400 may support and support the striking plate driving piston 410 to maintain an initial state in which it is not extended.

When the switch 310 of the manual switch unit 300 is pressed by an operator, the pneumatic valve unit 200 starts inflow and recovery of air in the first mode state.

Pneumatic pressure introduced into the manual switch unit 300 is discharged through the switch pneumatic discharge port 340 is supplied to the mode 1 air inlet 240. The air pressure supplied to the mode 1 air inlet 240 pressurizes the valve piston 270 to be converted to the second mode as shown in FIG. 5B.

The air introduced through the external air inlet 211 in the second mode is discharged through the second air outlet 223. The air discharged through the second air outlet 223 branches in two directions via the second pneumatic branching unit 710 as shown in FIG. 4. Air in one direction branched from the second pneumatic branch 710 is introduced into the second pneumatic inlet 430 of the striking plate 400, the air in the other direction is reinforced pneumatic inlet 520 of the blow reinforcement unit 500 Flows into.

As the blow plate 400 is supplied with air pressure to the second pneumatic inlet 430, the blow plate driving piston 410 is extended so that the blow plate 450 hits the light guide plate LGP as shown in FIG. . Here, the pneumatic pressure previously introduced through the first pneumatic inlet 420 and supported so that the striking plate driving piston 410 is not extended is introduced into the valve body 210 through the first air outlet 221 and thus through the second exhaust port. Exhausted through 215. The pneumatic pressure introduced through the first pneumatic inlet 420 is relatively smaller in size than the pneumatic introduced through the second pneumatic inlet 430, so that the impact plate driving piston 410 can be smoothly moved.

At this time, the striking reinforcement unit 500 is moved together in conjunction with the movement of the striking plate 450, the reinforcement piston 540 is moved in the same direction as the striking plate 450 by the inertia according to the movement. The reinforcing pneumatic inlet 520 and the reinforcing pneumatic outlet 530 are opened by the movement of the reinforcing piston 540, and the pneumatic flow into the reinforcing pneumatic inlet 520 is discharged to the reinforcing pneumatic outlet 530.

The pneumatic pressure discharged through the reinforced pneumatic outlet 530 is introduced into the valve body 210 through the mode 2 air inlet 260, and presses the valve piston 270 to switch back to the mode 1.

As the mode 1 is switched again, the supply direction of the pneumatic pressure is changed, and the striking plate driving piston 410 is instantaneously restored to an unextended state.

That is, since the pneumatic supply direction is switched by the striking part 500 when the striking plate 450 presses the LGP, the striking plate 450 is forced to move quickly to the rear (initial state). The contact time between the light guide plate LGP and the striking plate 450 is minimized. Accordingly, the striking force of the LGP may be maximized.

Here, when the operator continues to press the switch 310, the blow plate 450 is switched in a short time because the pneumatic valve unit 200 is continuously switched to the first mode and the second mode and supplies and retrieves the pneumatic pressure. Successively hitting the light guide plate (LGP). As a result, the plurality of LGPs may be aligned in a short time.

Here, the contact time of the light guide plate (LGP) and the striking plate 450 may be adjusted by adjusting the gap and frictional force between the reinforcing piston 540 of the striking reinforcement unit 500 and the inner wall surface of the reinforcing support frame 510.

When the manual pressurization of the switch 310 is removed, the striking reinforcement part 500 returns the reinforcement piston 540 to the initial state by the spring 580, and the switch piston 360 is also the initial state by the switch spring 380. Return to.

As described above, according to the pneumatic blower for aligning the light guide plate of the present invention, a pneumatic blower that is heavy due to a large capacity pneumatic cylinder is provided by providing a device of a size and weight suitable for use by a worker through a blow reinforcement unit for increasing instantaneous blow force. It can save unnecessary labor that was consumed by using blower or hitting bag.

In addition, it is possible to eliminate the side cracking failure by the uniformity of the hitting method that was previously uneven according to the working skill and environment.

Embodiment of the pneumatic impactor for alignment of the light guide plate described above is merely exemplary, and those skilled in the art to which the present invention pertains can make various modifications and other equivalent embodiments therefrom. You can see well. Therefore, it will be understood that the present invention is not limited to the forms mentioned in the above detailed description.
