摘要:波峰焊是將熔融的液態(tài)焊料,借助與泵的作用,在焊料槽液面形成特定形狀的焊料波,插裝了元器件的PCBA置與傳送鏈上,經(jīng)過某一特定的角度以及一定的浸入深度穿過焊料波峰而實(shí)現(xiàn)焊點(diǎn)焊接的過程。作為一種傳統(tǒng)的焊接技術(shù),目前波峰焊依然在電子領(lǐng)域發(fā)揮著積極作用,所以波峰焊機(jī)器設(shè)備的智能化和節(jié)能越來(lái)越重要。本案例使用顧美觸摸屏PLC一體機(jī),全自動(dòng)控制控制波峰焊工藝,使生產(chǎn)流程更加簡(jiǎn)潔,工藝更加優(yōu)化,節(jié)能和智能化。
一.原理
按照工藝流程,通過PLC編程控制波峰焊設(shè)備各個(gè)工位運(yùn)作,在有產(chǎn)品到達(dá)噴霧位置或波峰位置的時(shí)候,自動(dòng)啟動(dòng)噴霧和波峰,并可以實(shí)時(shí)采集溫度到PLC中,再通過PLC傳到觸摸屏上實(shí)現(xiàn)實(shí)時(shí)溫度監(jiān)控,并可以實(shí)時(shí)監(jiān)控各個(gè)工位部件的運(yùn)作狀態(tài)。
二.優(yōu)勢(shì)
與傳統(tǒng)的工藝具有以下優(yōu)點(diǎn):
1.能精確的控制錫爐的開關(guān)時(shí)間,提前熔錫,解決了用戶在使用過程中去定時(shí)打開錫爐和關(guān)閉錫爐的問題,這套系統(tǒng)還為客戶設(shè)計(jì)了三個(gè)定時(shí)的開關(guān)錫爐的時(shí)間,按照正常上班,周末上班,其他定時(shí)開關(guān)錫爐,能有效的為客戶節(jié)省電費(fèi)和時(shí)間。
2.本系統(tǒng)自帶4路模擬量輸入功能,能有效的實(shí)時(shí)監(jiān)控預(yù)熱溫度,錫爐溫度作用,并設(shè)有自動(dòng)保護(hù)功能,在錫爐熔錫溫度沒有到達(dá)設(shè)定溫度時(shí)不能手動(dòng)自動(dòng)啟動(dòng)波峰,對(duì)產(chǎn)品實(shí)施了保護(hù)功能。
3.在全自動(dòng)狀態(tài)下,噴霧和波峰都由產(chǎn)品來(lái)控制,當(dāng)有產(chǎn)品到達(dá)噴霧位置時(shí),控制系統(tǒng)自動(dòng)啟動(dòng)噴霧,并且可以根據(jù)產(chǎn)品寬度手動(dòng)設(shè)置噴霧速度,當(dāng)產(chǎn)品完成噴霧時(shí)自動(dòng)關(guān)閉噴霧,再有產(chǎn)品來(lái)時(shí)再次啟動(dòng);當(dāng)產(chǎn)品到達(dá)波峰位置時(shí)自動(dòng)啟動(dòng)波峰,產(chǎn)品焊接完成自動(dòng)關(guān)閉波峰(可手動(dòng)設(shè)置)。節(jié)省了助焊劑和電能,真正達(dá)到節(jié)能作用!
4.手動(dòng)狀態(tài)下,可以手動(dòng)開啟關(guān)閉各個(gè)原件,可以有效的調(diào)機(jī)和查找問題。
5.參數(shù)設(shè)置;在參數(shù)設(shè)置的畫面里,可以設(shè)置傳動(dòng)運(yùn)輸速度,自動(dòng)噴霧速度,生產(chǎn)產(chǎn)量,自動(dòng)開關(guān)錫爐時(shí)間,定期維護(hù)時(shí)間等,可根據(jù)要求添加。
6.本系統(tǒng)具有自動(dòng)計(jì)數(shù)功能,可以統(tǒng)計(jì)產(chǎn)品的數(shù)量,并可以設(shè)定產(chǎn)量,當(dāng)?shù)竭_(dá)產(chǎn)量是自動(dòng)發(fā)出信號(hào),提醒客戶計(jì)數(shù)到達(dá)。
7.本系統(tǒng)還有具有維護(hù)時(shí)間到期提醒,通過設(shè)定維護(hù)時(shí)間定期提醒客戶維護(hù),從而增加機(jī)器的使用壽命。
8.本系統(tǒng)還具有密碼鎖機(jī)功能;在這套系統(tǒng)共設(shè)置五期的定期鎖機(jī)功能,可供客戶自己選擇,時(shí)間一到期自動(dòng)停止機(jī)器運(yùn)行,解決了客戶收款難問題。
9.自動(dòng)報(bào)警功能,當(dāng)溫度過高或過低自動(dòng)報(bào)警。
三.控制系統(tǒng)
配置可編程控制器與觸摸屏一體機(jī),把波峰焊的性能智能化、自動(dòng)化、人性化變成現(xiàn)實(shí),具有穩(wěn)定性高、功能豐富、操作簡(jiǎn)單、使用方便、控制靈活等優(yōu)點(diǎn)配置有4路模擬量輸入2路模擬量輸出可以對(duì)多路溫度進(jìn)行監(jiān)控。
四.操作性能
1.觸摸屏可中英文顯示,具有豐富的顯示功能,將波峰焊的各個(gè)工位運(yùn)行狀態(tài)和采集到錫爐熔錫的溫度、加熱器工作狀態(tài)、當(dāng)前時(shí)間、報(bào)警信息等準(zhǔn)確直觀的顯示出來(lái)。簡(jiǎn)單的通過手指點(diǎn)擊觸摸屏進(jìn)行操作設(shè)置,并可查核、設(shè)定和修改各種調(diào)節(jié)參數(shù),實(shí)現(xiàn)人機(jī)對(duì)話,易懂、易學(xué)、易記,操作簡(jiǎn)單、方便。
五.綜合特點(diǎn)
1.采用可編程控制器跟觸摸屏PLC一體機(jī),鍋爐的運(yùn)行狀態(tài)清晰可見。所有操作都簡(jiǎn)單地通過點(diǎn)擊觸摸屏輕松完成,鍋爐控制器的超級(jí)顯示功能、控制功能十分齊全。
2.能全自動(dòng)的啟動(dòng)噴霧,噴霧完成后,自動(dòng)關(guān)閉噴霧,節(jié)省了原料;全自動(dòng)波峰可以自動(dòng)控制波峰的起落,節(jié)省了電能!達(dá)到了節(jié)省原料節(jié)省能源的功效。
