自動(dòng)點(diǎn)膠機(jī)焊接過(guò)程中，會(huì)遇到焊接不良的問(wèn)題，這些問(wèn)題詳細(xì)表現(xiàn)有漏焊、虛焊、連焊、焊點(diǎn)不潤(rùn)滑等現(xiàn)象的，濟(jì)南雙組份打膠機(jī)廠家提示大家，針對(duì)這些焊接不良問(wèn)題，我們認(rèn)真察看，找出構(gòu)成這些不良的緣由，然后再有針對(duì)性的去處置。
In the welding process of automatic dispensing machine, we will encounter problems of poor welding. These problems are manifested in detail as missed welding, virtual welding, continuous welding, non-lubrication of solder joints and so on. Jinan two-component dispensing machine manufacturer reminds us that in view of these welding problems, we should carefully observe and find out the causes of these defects, and then deal with them pertinently.
1、漏焊。漏焊普通是指在焊接過(guò)程中，焊盤(pán)上沒(méi)有錫的現(xiàn)象。自動(dòng)點(diǎn)膠機(jī)呈現(xiàn)這種情況的緣由大致有兩點(diǎn)，一是烙鐵頭沒(méi)有接觸到焊點(diǎn)，這個(gè)時(shí)分我們就要調(diào)整該點(diǎn)的坐標(biāo)，使烙鐵頭接觸到焊點(diǎn)，這樣就不會(huì)呈現(xiàn)漏焊;在一個(gè)就是焊盤(pán)外表氧化比擬嚴(yán)重，錫基本粘不在上面。
1. Leakage welding. Leakage welding generally refers to the phenomenon that there is no tin on the pad during the welding process. There are roughly two reasons for this situation in automatic dispensing machine. One is that the soldering head does not touch the solder joint. At this time, we need to adjust the coordinates of the spot so that the soldering head touches the solder joint, so that there will be no leak soldering; the other is that the surface of the soldering pad is oxidized seriously, and the tin is basically not adhered to it.
2、虛焊。虛焊普通是指在焊接過(guò)程中看上去焊點(diǎn)還能夠，實(shí)踐上焊接時(shí)不撈的或是透錫量不行。構(gòu)成這種情況的緣由首要是烙鐵頭在焊盤(pán)上的停留時(shí)間不行或是溫渡過(guò)低構(gòu)成的。因此我們只需延伸烙鐵頭的停留時(shí)間或是升高溫度就能夠處置的
2. Virtual welding. Virtual welding generally means that the solder joint can be seen in the process of welding, but in practice it is not salvaged or tin penetration is not good. The main reason for this situation is that the retention time of the soldering head on the pad is not good or the temperature is too low. So we only need to extend the residence time of the soldering head or raise the temperature to dispose of it.

3、連焊。連焊普通是指緊鄰的幾個(gè)兩個(gè)焊點(diǎn)或是幾個(gè)焊點(diǎn)的焊盤(pán)鏈接在一同的現(xiàn)象。構(gòu)成此種現(xiàn)象的緣由要么是送錫量太多或是兩個(gè)點(diǎn)之間的空隙太小所構(gòu)成的。遇到這種情況，應(yīng)該削減錫量，然后在看能否是烙鐵頭的方位能否正確，如不正確，應(yīng)及時(shí)停止調(diào)整
3. Continuous welding. Continuous welding usually refers to the phenomenon that several adjacent solder joints or pads of several solder joints are linked together. The reason for this phenomenon is either too much tin feeding or too small gap between the two points. In this case, we should first reduce the amount of tin, and then see if the orientation of the iron head is correct. If not, we should stop adjusting in time.
4焊點(diǎn)不潤(rùn)滑、拉尖。焊點(diǎn)不潤(rùn)滑、拉尖是指焊過(guò)之后焊點(diǎn)成型欠好或是有毛刺并有拉尖的現(xiàn)象。此種緣由首要是由于錫的活動(dòng)性欠好構(gòu)成的，這個(gè)有時(shí)分也和我們參數(shù)的設(shè)置欠好也是有一定緣由的，要么就是停留時(shí)間過(guò)長(zhǎng)，構(gòu)成助焊劑蒸發(fā)過(guò)快，在烙鐵頭的抬起過(guò)程中就會(huì)構(gòu)成拉尖的現(xiàn)象。這個(gè)假設(shè)經(jīng)過(guò)參數(shù)的設(shè)置無(wú)法處置的話，我們就要思索錫絲的問(wèn)題。
4. The solder joint is not lubricated and sharp. Unlubricated solder joints and pointed solder joints refer to the phenomenon of poor solder joint formation or burr and pointed solder joints after soldering. This is mainly due to the inadequate activity of tin, which is sometimes due to the inadequate setting of our parameters. Either the residence time is too long and the flux evaporates too fast, which will lead to the phenomenon of tightening during the lifting process of the soldering head. If this assumption can not be dealt with by setting parameters, we should consider the problem of tin wire.
后，在焊接過(guò)程中，呈現(xiàn)上述這些不良焊點(diǎn)的緣由也有可能是由于烙鐵頭該換而沒(méi)有及時(shí)改換。更多關(guān)于雙組份打膠機(jī)的精彩內(nèi)容請(qǐng)收藏我們的官網(wǎng)：http://linshi.jncsjx.com謝謝支持。
Finally, in the welding process, the reason for these bad solder joints may also be that the soldering head should be replaced instead of being replaced in time.
