自動點膠機設備本身是控制膠水吐出量和吐出時間的裝置,對點膠機膠水要求方面,膠水一定不能有氣泡,一個小小氣即會造成許多焊盤沒有膠水,造成空打現(xiàn)象,導致產(chǎn)生不合格的產(chǎn)品,所以每次中途更換膠管時必須排空連接處,對于膠水的固化,一般生產(chǎn)廠家已給出溫度曲線,在實際應盡可能采用較高溫度來固化,使膠水固化后有足夠強度。
Automatic dispensing machine equipment itself is to control the amount of glue spit out and spit out the time of the device, the dispensing machine glue requirements, glue must not have bubbles, a small gas will cause many pads without glue, resulting in the phenomenon of empty punching, resulting in the production of unqualified products, so each midway to replace the hose must be emptied connection, for the curing of glue, General manufacturers have given the temperature curve, in practice should be as far as possible to use a higher temperature to solidify, so that the glue after curing has sufficient strength.
膠水的粘度直接影響點膠的質(zhì)量,粘度大,則膠點會變小,甚至拉絲;粘度小,膠點會變大,進而可能滲染焊盤。點膠過程中,應對不同粘度的膠水,選取合理的背壓和點膠速度。所以自動點膠機設備應根據(jù)不同同品質(zhì)的膠水、點膠機工作環(huán)境溫度等情況來來選擇壓力。環(huán)境溫度高則會使膠水粘度變小、流動性變好,這時需調(diào)低背壓即可保證膠水的供給,反之亦然。
The viscosity of the glue directly affects the quality of the dispensing, the viscosity is large, then the glue point will become smaller, or even brushed, the viscosity is small, the glue point will become larger, and then may seep the pad. In the process of dispensing, the glue with different viscosity should be selected, and reasonable back pressure and dispensing speed should be chosen. Therefore, automatic dispensing machine equipment should be based on different quality of glue, dispensing machine operating environment temperature and other conditions to choose the pressure. High ambient temperature will make the glue viscosity smaller, better fluidity, then need to lower the back pressure to ensure the supply of glue, and vice versa.
自動點膠機設備點膠量的大小根據(jù)工作經(jīng)驗,膠點直徑的大小應為焊盤間距的一半,貼片后膠點直徑應為膠點直徑的1.5倍,這樣即可以保證有充足的膠水來粘結(jié)元件又避免過多膠水浸染焊盤,點膠量多少由螺旋泵的旋轉(zhuǎn)時間長短來決定,實際中應根據(jù)室溫、膠水的粘性等選擇泵的旋轉(zhuǎn)時間。總之,使用自動點膠機可大大提高生產(chǎn)效率和減小產(chǎn)品的報廢,節(jié)省膠水,便可達到產(chǎn)品量化和提高經(jīng)濟效率的目的。
The size of the dispensing device of automatic dispensing machine according to the working experience, the diameter of the rubber point should be half the spacing of the pad, After the patch, the diameter of the adhesive point should be 1.5 times times the diameter of the glue point, so that you can ensure that there is sufficient glue to bond the element and avoid too much glue dipping pad, the amount of dispensing is determined by the length of the spiral pump rotation time, in practice should be based on room temperature, glue viscosity and other choice of pump rotation time. In short, the use of automatic dispensing machine can greatly improve production efficiency and reduce product scrapping, save glue, you can achieve product quantification and improve economic efficiency purposes
