Description
Technical field
This utility model is related to laser engraving apparatus field, and specifically a kind of laser carries out accurate engraving to light guide plate
Equipment.
Background technology
There are the various ways such as LCD, LED widely using as the display of IT product.Wherein LED because energy consumption it is low,
The reasons such as resolution is high, maximization occupy mainstream market.LED cannot be imaged after self-luminous, need to be through imaging device ability
It is implemented as picture, but backlight is needed using imaging device providing light source.Backlight is divided into directly according to the position distribution of light source
Following formula and side incident type, as lightening representative side incident type in occupation of main middle and high end market.
In order that the light source of side light-in backlight becomes uniformly area source from line source to need to carry out essence to light guide plate
Close pattern processing.The pattern processing mode of light guide plate has printing, etching, and injection etc. and utilizes laser beam at the method for physical property
Laser processing.It is wherein conventional for laser carving method.
Prior art laser engraving equipment as shown in figure 1, it include generating laser 8, mobile platform 9, stone material matter it is flat
Platform 10, Y-axis rail 11, linear electric motors 12, reflecting mirror 13, stone frame 14, X-axis rail 15, light guide plate 16, light collecting lenss 17.It is existing
The vibration that technology 1 causes to absorb X-axis back and forth movement, in bottom the platform 10 of stone material matter is constituted.The top of platform 10 has
Y-axis rail 11 makes mobile platform 9 to move with Y-axis.Mobile platform 9 is felt by the linear electric motors 12 ordered are received with rule
Know the position of Y-axis.Generating laser 1 and optical frames 13 are arranged at the top of platform 10, and arrange X on the stone frame 7 that can bear vibration
Axle rail 15, the light beam from the transmitting of generating laser 8 is by relying on the light harvesting of light collecting lenss 17 after optical mirror 13.Light guide plate 16
Movement in being placed on after mobile platform 9 to prevent processing is fixed by vacuum pump.Light collecting lenss 12 are ordered by controller is received
The linear electric motors of order back and forth movement on X-axis rail 15.
As shown in Figure 2 and Figure 3, prior art operation principle is：Start the light beam launched by reflection from generating laser 8
Mirror 13 is radiated on light collecting lenss 17, and at this moment light collecting lenss 17 pass through the linear electric motors 12 for receiving control command on X-axis rail
Carry out back and forth movement and the pattern engraving of a line a line is proceeded by light guide plate 16 using the laser beam for irradiating.At this moment exist
The time point linear electric motors 12 for processing a line are transplanted on next stride by receiving the order of controller light guide plate 16.
Prior art laser engraving equipment exist shortcoming be：
1 pattern processing machine former as described above be by light collecting lenss 17 after X-direction or so back and forth movement a line one
The equipment that row pattern is processed and mobile platform 9 carrys out reprocessabilty to Y-direction stepping.In this case per a line, processing is required for
Acceleration and deceleration, and because the inertia of acceleration and deceleration causes vibrations, such vibrations to increase error to precise pattern processing.
2 need using the strong stone material of hardness to solve this vibrations, and the existing mobile difficult and valency because equipment is reppeared
The problem that lattice are jumped up.
3 often row plus man-hour requirements accelerate, time of deceleration but the time of acceleration-deceleration cannot processing graphic pattern, and
And because Y-axis transfer time point also cannot processing graphic pattern be allowed to large losses time reduce productivity.
4 other X-axis need high-speed motion to make the bearing being mounted on X-axis rail 15 usually wear and tear needs replacing to cause expense
The problems such as movable rate of rising and equipment is reduced
5 other display devices maximize and cause light guide plate also to maximize.At this moment in order to process the light guide plate X-axis of maximization
Displacement be also required to increase, but the increase of displacement can cause the loss of laser power and occur in laser power
Difference, having an impact to processing processing uniform pattern on large-scale light guide plate, and carve site precision cannot accomplish less than 80 μm.
6 need the laser generator and optical device of plural number in addition to improving productivity, and at this moment manufacturing cost will be big
Width increases.
