Description
Technical field
The present invention relates to a kind of production facilities of liquid crystal display assembling parts, the feed box of the polaroid on especially a kind of liquid crystal display automatic production line.
Background technology
Liquid crystal display is extensively incorporated on the display equipments such as mobile phone, TV, telltale.In the manufacturing process of liquid crystal display, need to use a kind of important parts: polaroid, this is a kind of very thin extremely fragile flap, and effects on surface purity requirements is very high, so cannot manual operations be used, but feed box is adopted to add the mode of getting sheet equipment and realize mechanized operation.
General feed box as shown in Figure 1, it is a box body, height or the width of box body are consistent with polaroid, arrange gear edge at opening part, in box body, afterbody arranges charging ram, and charging ram pushes up this folded polaroid from behind, this folded polaroid is allowed to move to opening part, when arriving gear along position, four periderm gears are along blocking, and then slice getting device takes monolithic polaroid away from sucking-off above.The object of charging ram is to allow the polaroid stacked continue to remain on opening part, realizes friction feeding.
As previously mentioned, because the polaroid for the production of liquid crystal display is stacked when feed states, add electrostatic and the high relation of surface finish own, often occur that multi-disc (be many with 2 ~ 3) polaroid is sticked together by the situation of getting sheet equipment and taking away.The situation even occur that large quantities of polaroid is all sucked out, dropping, these all can cause the damage of polaroid, scrap.According to field statistics, according to the difference of polaroid dimensions, the loss caused because of above-mentioned situation is 2% ~ 30%, and size more lossy is more.
Summary of the invention
The present invention is exactly the defect in order to overcome the existing polaroid feed box described in background technology, invents a kind of polaroid feed box that can improve feeding effect, reduce multi-disc polaroid adhesion accident.
This liquid crystal display polaroid feed box, comprises box body, feeding rod, and the opening part of box body is provided with gear edge, it is characterized in that: the angle of gear edge and cartridge inner surface is provided with slope.
Box body and domatic angle are 5 ~ 60 °.
Be preferably: angle is 10 ~ 50 °.
Further preferably: angle is 15 ~ 45 °
Further preferred: angle is 20 ~ 40 °, optimum effective scope is 20 ~ 35 °.
Owing to there is described slope, so the polaroid in feed box of the present invention is sucked out from box to opening part, the track experienced is no longer straight line, but there is a track closed up gradually, can allow like this stack polaroid when closing on opening and inboard wall of cartridge form the matching relationship of an interference, because of the elasticity of polaroid, cause slight being bent outwardly, the polaroid stacked is separated.So the present invention can reduce the situation of multi-disc polaroid adhesion by actv., according to field experiment, the average rate of dropping can be reduced within 10%.In most preferred situation, 2 adhesion rates can be low to moderate 0.24%, 3 and above adhesion rate be 0! This and prior art ratio are impayable progress, have increased substantially production efficiency, have saved cost.

Fig. 3, experiment effect list of the present invention.
Detailed description of the invention
As Fig. 2, the present invention includes box body 1, feeding rod 2, the opening part of box body is provided with gear along 3, it is characterized in that: the angle kept off along 3 and box body 1 inside face is provided with slope 4.Slope 4 has along place at each gear.The polaroid 5 stacked is placed in box body 1, push away forward after feeding rod 2 withstands on, feeding rod is had an effect with pusher cylinder, and reclaimer device 6 is that dependence suction, sticky means are come outermost polaroid 5 sucking-off outside opening part, is transported to lower road and carries out fitting work.Due to the existence on slope 4, the polaroid by opening part can produce slight being bent outwardly, and the polaroid be sticked together thoroughly is separated, and reduces adhesion accident.
According to the present invention, carried out a large amount of experiments to the angle of slope and cartridge inner surface, the angular range obtained is 5 ~ 60 °, and height 6 ~ 9mm is good.
Concrete observed data is as Fig. 3, choose 32.2 × 29.9, 51.91 × 29.82, 59.8 × 37.06, 62.2 × 40.4, 61 × 35.5, 63.3 × 47.9, 69.2 × 43.1, 70.81 × 47.9, 73.8 × 57.1, 76.89 × 51.36, 78.1 × 52.6, 77.1 × 58.4, 86.7 × 58.08, 94.1 × 54.6, 86.8 × 65.5, 101.4 × 58.25 and 100.5 × 56.9(unit mm) etc. the polaroid of 17 kinds of specifications, test by the current yield of 5000, ramp angles is from 5 ~ 60 °, every 5 ° of scopes, record 2 and above polaroid adhesion fraction defective.
On the whole, adopt the present invention, the average fraction defective of 2 adhesions is lower than 10.8%, and the situation of 3 adhesions is almost 0.And do not adopt the corresponding data of slope (ramp angles is 0 °), from this size of 70.81 × 47.9mm up, adhesion fraction defective is just more than 13%, and the fraction defective of 86.8 × 65.5mm specification even reaches 30.44%, has a strong impact on production.
Below enumerate multiple specification data, based on the bad accident rate of 2 adhesions, be described:
Embodiment 1, the polaroid of 32.2 × 29.9mm, when 5 ° of angles, adhesion accident rate is 2.12%; When 30 ° of angles, adhesion accident rate is 0.37%; When 60 ° of angles, adhesion accident rate is 1.93%.
Embodiment 2, the polaroid of 69.2 × 43.1mm, when 5 ° of angles, adhesion accident rate is 6.02%; When 30 ° of angles, adhesion accident rate is 0.58%; When 60 ° of angles, adhesion accident rate is 4.36%.
Find, when the size of polaroid is larger time, because its stiction force can increase, so angle needs to improve just can obtain better effect simultaneously.
Embodiment 3, the polaroid of 86.7 × 58.08mm, when 10 ° of angles, adhesion accident rate is 7.75%; When 30 ° of angles, adhesion accident rate is 0.22%; When 60 ° of angles, adhesion accident rate is 6.9%.
Embodiment 4, the polaroid of 100.5 × 56.9mm, when 10 ° of angles, adhesion accident rate is 7.82%; When 30 ° of angles, adhesion accident rate is 0.39%; When 60 ° of angles, adhesion accident rate is 9.89%.
From above-mentioned great many of experiments, 32.2 × 29.9,51.91 × 29.82,59.8 × 37.06,62.2 × 40.4,61 × 35.5,63.3 × 47.9,69.2 × 43.1,70.81 × 47.9,73.8 × 57.1,76.89 × 51.36,78.1 × 52.6,77.1 × 58.4,86.7 × 58.08,94.1 × 54.6,86.8 × 65.5,101.4 × 58.25 and these 17 kinds of specifications of 100.5 × 56.9mm are sizes of conventional liquid crystal display polaroid, the feeding of polaroid is carried out with feed box of the present invention, in the reduction of adhesion accident rate, effect obviously, well beyond expectation.And structure is simple, easily manufactured.
