Ho ea ka litlhoko tsa theknoloji tsa bahlahisi ba fapaneng, mekhoa e nepahetseng ea ho lekanya bolelele ba li-tubes ka mekhoa e fapaneng ea ho lekanya bolelele.Ho na le tse latelang:
1, Tekanyo ea bolelele ba grating
Molao-motheo oa motheo ke: lipheletsong tse ka ntle tsa li-tubes tse nepahetseng li fanoa ka bolelele bo tsitsitseng ba li-grating tse peli, ho sebelisoa ha grating e se nang rodless cylinder e haufi le lipheletsong tsa li-tubes tse nepahetseng, ho sebelisa tšitiso ea leseli ho finyella tekanyo e nepahetseng ea bolelele ba tube.
E tšoauoa ka ho nepahala ho phahameng.Empa tekanyo e theko e boima ebile e thata ho e boloka, phello ea lerōle le vibrate ke sebaka se hlokolosi haholo.

2, Tekanyo ea bolelele ba khamera.
Tekanyo ea bolelele ba k'hamera ke ts'ebeliso ea ts'ebetso ea litšoantšo ho fihlela tekanyo e nepahetseng ea bolelele ba li-tubes, molao-motheo ke letoto le lekanang la li-switch tsa photoelectric tse kentsoeng ka har'a tube ea conveyor e nepahetseng ka nako e itseng, ho eketseha ha leseli le khamera karolong e 'ngoe.Ha li-tubes tse nepahetseng sebakeng sena li ka khethoa ke lik'hamera tse nepahetseng tsa bolelele ba li-tube tse nkang setšoantšo skrineng se le maemong a ipapisitseng le switch ea photoelectric.
Likarolo li fumaneha bakeng sa ho lekanya marang-rang, li-tubes tse nepahetseng li ka fumanoa ka ho lekanya bolelele ba data ha sebaka se selelele, ho se na nako.Khaello ke: Haeba u sa fane ka mohloli oa khanya, li-tubes tse nepahetseng li tla kena-kenana le tšitiso e ka ntle, empa ka mor'a ho sebelisa leseli ka lebaka la li-tubes tsa ad hoc precision ka mor'a hore li-tube tsa chamfered li qetelle ha khanya e khanyang e le matla haholo. ho baka diphoso tsa ho bala.

3, Encoder e lekanya bolelele
Molao-motheo ke ho kenya encoder ka silindara ho silindara ho khothaletsa ts'ebeliso ea li-tubes tse nepahetseng ka har'a motsamao oa li-roller ka lehlakoreng le leng la letoto le ntseng le phahama la li-switch tsa photoelectric, li-tubes tse nepahetseng li fihlelleha ha li-cylinders tsa switch photoelectric li sutumelletsa pheletso ea tube, ho tsoa ho 'malo oa ho rekota oa khouto, o fetotse sekhahla sa silinda, hore o tsebe ho bala bolelele ba li-tubes tse nepahetseng.
E tšoauoa ka tlhokahalo ea ho phahamisa li-tubes tse nepahetseng tse lekanyang bolelele.Ho phaella moo, ho na le phetoho e itseng ea photoelectric e lemoha phoso, u ka 'na ua hloka ho lekanyetsoa ka botlalo.

4, Encoder ea ho lekanya bolelele e ntlafalitsoeng
Mokhoa ona ke tekanyo e sa tobang, ka ho lekanya sebaka se pakeng tsa li-tubes tse peli tse nepahetseng ka ntlha e fapaneng e lekantsoeng ka mokhoa o sa tobang oa bolelele ba tube.Ka li-tubes tse nepahetseng lipheletsong tse peli tsa seteishene sa ho lekanya ho theha koloi e telele, boemo ba pele ke boemo ba zero, sebaka sa L. Ebe u tsamaisa bolelele ba tube e nepahetseng ea mohlophisi ho isa pheletsong e 'ngoe le e 'ngoe ea sebaka se tsamaeang (L2, L3), L-L2- L3, ke bolelele ba li-tubes tse nepahetseng.
