Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only for explaining the utility model, and be not used in restriction the utility model.
Please refer to Fig. 1-Fig. 4, as shown in Figures 1 to 4, the solar battery sheet operplate printing table top that the utility model provides comprises metal table top 1, lower metal table top 5, glass 4 and LED backlight 6, and upper metal table top 1 is oppositely arranged with lower metal table top about 5; Wherein:
Upper metal table top 1 offers trough body structure, and trough body structure runs through the upper and lower surface of metal table top 1; Particularly, trough body structure comprises the upper groove body 2 and lower groove 3 that set gradually from top to bottom, and the groove width of upper groove body 2 is greater than the groove width of lower groove 3, thus forms a step between upper groove body 2 and lower groove 3;
Glass 4 is fixedly installed in upper groove body 2, concrete, and glass 4 is fixedly installed on the step that formed between upper groove body 2 and lower groove 3.And the width of glass 4 and length match with the groove width of upper groove body 2 and flute length respectively, and the thickness of glass 4 and the groove depth of upper groove body 2 match; Thus make the upper surface of the upper surface of glass 4 and upper metal table top 1 in same level, and realize seamless link between glass 4 and upper metal table top 4; Even if thus use for a long time, the position of glass 4 also can not change, and thus can not cause the out-of-flatness of printing table; Reduce further the fragment that solar battery sheet causes in printing process, improve the yield rate of product, decrease printing table maintaining and obtain difficulty, improve Housing Starts; And because glass 4 is fixedly installed in upper groove body 2, thus in use do not need to regulate the levelness between glass 4 and upper metal table top 1, thus facilitate the use of solar battery sheet operplate printing table top, save operation.
The position that lower metal table top 5 up and down cell body 3 is relative is fixedly installed LED backlight 6, and LED backlight 6 convexedly stretches in lower groove 3, and the size of LED backlight 6 and the size of lower groove 3 match.
Upper metal table top 1 is installed in aggregates with lower metal table top about 5.
Wherein, glass 4 is pasted and fixed in upper groove body 2 by inorganic glue, particularly, is achieved a fixed connection between four sides of the bottom surface of glass 4 and step, glass 4 and the madial wall of upper groove body 2 by inorganic glue.Wherein, the main feature of this inorganic glue has: 1. after the glue solidifies, volume can not expand; 2., when higher than 50 DEG C, can not come unstuck; 3. the solubility in alcohol is lower; 4. be convenient to clear up residual solid gum.
Wherein, LED backlight 6 is Height Adjustable; Particularly, the height of LED backlight 6 regulates by screw, and particularly, the pedestal of LED is fixed on lower metal table top 5 by four screws, and LED is fixed on LED pedestal by four screws again, and four screw sides are provided with four jackscrews.The height of LED is regulated as follows by four jackscrews and four fixed screws: 1. unclamp four fixed screws; 2. rotate jackscrew, the tighter LED of jackscrew is higher, and the more loose LED of jackscrew is lower; 3. after adjusting to proper height, tighten four fixed screws, locking position is to prevent LED change in location.Height Adjustable due to LED backlight, thus can be adjusted to the gap between LED backlight and glass minimum, thus facilitate capture.Wherein, when printing, equipment is the particular location determining silicon chip, needs to carry out capture to determine position of silicon wafer, so capture here refers to silicon chip edge capture to two edges of silicon chip.Lamp and glass spaces less, the reflex of glass to light is more not obvious, and capture is more clear more accurate.
Further, preferably, the brightness of LED backlight 6 is adjustable.Particularly, the brightness of LED backlight regulates by regulating the power output of LED, and the brightness of power output more headlight is higher, and the brightness of power more lampet is less.
Wherein, upper metal table top 1 is the metal material after cure process, and particularly, upper metal table top 1 is the stainless steel through cure process.This is because upper metal table top 1 has following particularity: 1. the flatness of table top is very high; 2. metal table top uniform aperture digging diameter 1mm in the scope of center 155mm × 155mm; 3. dig the cell body of two long 240mm of the dark 7mm of wide 5mm.Wherein, the light transmission of glass 4 is greater than 90%, and its hardness is greater than 7.
In another specific embodiment of the present utility model, the quantity of trough body structure is 3, and the quantity of glass 4 corresponds to 3, and the quantity of LED backlight 6 corresponds to 3; As shown in Figure 5.Why the quantity of trough body structure is set to 3 by the utility model, and the quantity correspondence of glass 4 is set to 3, and the corresponding reason being set to 3 of quantity of LED backlight 6 is: operations area is increased, can keep good hardness simultaneously.Mean will be equipped with three cameras this is because arrange three LED, at different three points, capture is carried out to silicon chip, accurately can judge the particular location of silicon chip, improve the printing precision of printing machine.
The assembling process of the solar battery sheet operplate printing table top that the utility model provides is as follows:
1) metal table top 1 and lower metal table top 5 in preparation; Wherein, the size of upper metal table top 1 is 240mm × 240mm, and thickness is 10mm, and material is the stainless steel after sclerosis.The size of lower metal table top 5 is 240mm × 240mm, and thickness is 15mm, and material is stainless steel.
2) on upper metal table top 1, offer trough body structure, trough body structure runs through the upper and lower surface of metal table top 1; Particularly, trough body structure comprises the upper groove body 2 and lower groove 3 that set gradually from top to bottom, and the groove width of upper groove body 2 is greater than the groove width of lower groove 3, thus forms a step between upper groove body 2 and lower groove 3;
Glass 4 is fixedly installed in upper groove body 2, concrete, and glass 4 is fixedly installed on the step that formed between upper groove body 2 and lower groove 3.And the width of glass 4 and length match with the groove width of upper groove body 2 and flute length respectively, and the thickness of glass 4 and the groove depth of upper groove body 2 match.
The foregoing is only preferred embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model.Obviously, those skilled in the art can carry out various change and modification to utility model and not depart from spirit and scope of the present utility model.Like this, if these amendments of the present utility model and modification belong within the scope of the utility model claim and equivalent technologies thereof, then the utility model is also intended to comprise these change and modification.
