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 extensively is 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 as thin as a wafer extremely fragile flap, and the effects on surface cleanliness requires very high, so can't use manual operations, realize mechanized operation but adopt feed box to add the mode of getting sheet equipment.
General feed box as shown in Figure 1, it is a box body, the height of box body or width are consistent with polaroid, at opening part the gear edge is set, afterbody arranges charging ram in the box body, and charging ram pushes up this folded polaroid from behind, allow this folded polaroid move to opening part, when arriving gear along the position, blocked by the gear edge all around, then slice getting device is taken the monolithic polaroid away from the front sucking-off.The purpose of charging ram is to allow the polaroid that stacks continue to remain on opening part, realizes friction feeding.
As previously mentioned, owing to be stacked for the production of the polaroid of liquid crystal display, add static and the high relation of surface finish own in feed states, the situation that multi-disc (take 2 ~ 3 as many) polaroid is sticked together and is got sheet equipment and take away often occurs.Even the situation that large quantities of polaroids all are sucked out, drop appears, these all can cause polaroid damage, scrap.According to field statistics, according to the difference of polaroid dimensions, the loss that causes because of above-mentioned situation is 2% ~ 30%, and size more lossy is more.
Summary of the invention
The present invention is exactly in order to overcome the defective of the described existing polaroid feed box of background technology, to invent a kind of polaroid feed box that can improve the 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 the gear edge, it is characterized in that: the angle of gear edge and cartridge inner surface is provided with the slope.
Box body and domatic angle are 5 ~ 60 °.
Be preferably: angle is 10 ~ 50 °.
Further preferred: angle is 15 ~ 45 °
Further preferred: angle is 20 ~ 40 °, and optimum effective scope is 20 ~ 35 °.
Owing to there is described slope, so the polaroid in the feed box of the present invention is from being sucked out to opening part in the box, the track that experiences no longer is straight line, but has a track that closes up gradually, can allow like this and stack polaroid when closing on opening and inboard wall of cartridge forms the matching relationship of an interference, because of the elasticity of polaroid, cause slight outwardly-bent, with the polaroid that stacks separately.So the present invention can actv. reduces the situation of multi-disc polaroid adhesion, according to field experiment, the average rate of dropping can be reduced in 10%.In the 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.
Description of drawings

Fig. 2, feed box structure of the present invention;
Fig. 3, experiment effect tabulation of the present invention.
The specific embodiment
Such 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: gear along 3 and the angle of box body 1 inside face be provided with slope 4.Slope 4 has along the place at each gear.The polaroid 5 that stacks is placed in the box body 1, feeding rod 2 withstands on the back and pushes away forward, feeding rod is had an effect with the pusher cylinder, and feeding equipment 6 is to rely on the means of inhaling, gluing to come 5 sucking-offs of outermost polaroid in the opening part outside, is transported to lower road and carries out fitting work.Because the existence on slope 4, can produce slight outwardly-bently by the polaroid of opening part, the polaroid that is sticked together is thoroughly separated, reduce the adhesion accident.
According to the present invention, the angle of slope and cartridge inner surface has been carried out a large amount of experiments, the angular range that obtains is 5 ~ 60 °, height 6 ~ 9mm is good.
Concrete observed data such 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 the mm of 100.5 * 56.9(unit) etc. the polaroid of 17 kinds of specifications, current yield by 5000 is tested, ramp angles is from 5 ~ 60 °, per 5 ° of scopes record 2 and above polaroid adhesion fraction defective.
On the whole, adopt the present invention, the situation that the average fraction defective of 2 adhesions is lower than 10.8%, 3 adhesion is almost 0.And do not adopt the corresponding data of slope (ramp angles is 0 °), since this size of 70.81 * 47.9mm up, the adhesion fraction defective just surpasses the fraction defective of 13%, 86.8 * 65.5mm specification even reaches 30.44%, has a strong impact on production.
Below enumerate a plurality of specification data, the bad accident rate of pressing 2 adhesions is the basis, describes:
The polaroid of embodiment 1,32.2 * 29.9mm, in 5 ° of angles, the adhesion accident rate is 2.12%; In 30 ° of angles, the adhesion accident rate is 0.37%; In the time of 60 ° of angles, the adhesion accident rate is 1.93%.
The polaroid of embodiment 2,69.2 * 43.1mm, in 5 ° of angles, the adhesion accident rate is 6.02%; In 30 ° of angles, the adhesion accident rate is 0.58%; In the time of 60 ° of angles, the adhesion accident rate is 4.36%.
Find simultaneously, when the size of polaroid is larger, because its stiction force can increase, can obtain better effect so angle need to improve.
The polaroid of embodiment 3,86.7 * 58.08mm, in 10 ° of angles, the adhesion accident rate is 7.75%; In 30 ° of angles, the adhesion accident rate is 0.22%; In the time of 60 ° of angles, the adhesion accident rate is 6.9%.
The polaroid of embodiment 4,100.5 * 56.9mm, in 10 ° of angles, the adhesion accident rate is 7.82%; In 30 ° of angles, the adhesion accident rate is 0.39%; In the time of 60 ° of angles, the adhesion accident rate is 9.89%.
By above-mentioned great many of experiments as can be known, 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 the liquid crystal display polaroid commonly used, carry out the feeding of polaroid with feed box of the present invention, reduction effect in the adhesion accident rate is obvious, well beyond expectation.And simple in structure, easily manufactured.
