Abstract: In order to realize the efficient supply and delivery of screws in the production line, then apply to the automatic product assembly line, this paper designs a screw feeder control system based on STC12C5410 single chip microcomputer. STC12C5410 is the hardware core controller of the system, including the function of material shortage alarm, arranging and conveying screws and so on. The system mainly realizes feeding by the photoelectric switch and solenoid valves, which effectively improves the efficiency and stability of screw conveying. In addition, the circuit of adjusting the torque of the electric batch and controlling the brake of the motor is designed, and the simulation and experiment are carried out to provide the technical preparation for the later integration of this function into the matching electric batch.
Key words : STC12C5410;screw feeder;torque control;motor brake control

    在自動(dòng)化生產(chǎn)線中,常用產(chǎn)品裝配中的擰緊螺絲環(huán)節(jié),采用自動(dòng)化設(shè)備鎖附螺絲已經(jīng)成為了大勢(shì)所趨。而螺絲供料機(jī)是自動(dòng)鎖附螺絲機(jī)的重要組成部分,它將機(jī)、電、氣融為一體,是一種自動(dòng)將螺釘排列并輸送的機(jī)構(gòu),為自動(dòng)化生產(chǎn)線上的主要技術(shù)設(shè)備之一。螺絲供料機(jī)合理的結(jié)構(gòu)和可靠的供料系統(tǒng),是螺絲供料機(jī)能夠安全可靠工作的兩個(gè)關(guān)鍵因素。

    傳統(tǒng)的螺絲供料機(jī)芯片采用AT89C51單片機(jī)作為核心,占用空間大,需要在配套電批上手動(dòng)調(diào)節(jié)電批的扭力,輸送螺釘程序沒有經(jīng)過優(yōu)化導(dǎo)致卡料率高[1]。因此本設(shè)計(jì)采用STC12C5410單片機(jī)為主控芯片,此款單片機(jī)為28個(gè)引腳封裝,可以實(shí)現(xiàn)功能的同時(shí)節(jié)省空間,不造成浪費(fèi)。本文控制開發(fā)了螺絲供料機(jī)的控制系統(tǒng),經(jīng)過實(shí)驗(yàn)驗(yàn)證,能夠使其穩(wěn)定高效地工作。傳統(tǒng)的螺絲供料機(jī)配套電批采用手動(dòng)調(diào)節(jié)電批扭力,以適應(yīng)不同型號(hào)的螺絲。本文設(shè)計(jì)了一種可對(duì)電批的扭力進(jìn)行調(diào)整,達(dá)到一定扭力制動(dòng)的電路,以適用于不同工件的擰螺絲工序。經(jīng)實(shí)驗(yàn)與仿真,為今后對(duì)配套電機(jī)的功能改進(jìn)提供了思路,具有很好的應(yīng)用前景。
