Kugadzirwa kwePCB yekudhinda resipi yekupisa kweHigh-Speed ​​​​POS Mechanisms

PCB yeprinta inoridzwa nethermal risiti inodzora musoro wemagetsi anodziya ane simba guru, mota inodya mapepa, mucheki, masensa uye kutaurirana kwePOS muchikamu chidiki. Dambudziko rayo guru rekugadzira nderenguva yesimba: bhodhi rinofanira kuendesa mapuroteni anodzokororwa ekupisa ukuwo mota nemitoro yemucheki ichigovana, pasina kugadzirisa logic kana kuchinja huwandu hweprint.

Highleap Electronics inogadzira mabhodhi ekudzora printa yerisiti yekupisa yakagadzirwa nevatengi uye maPCBA assembly ane controlled sourcing, SMT/through-hole assembly, inspection, programming uye functional testing inotsamira pavatengi. Hunhu hwekudhinda hunoenderana neprinta yakaburitswa, bepa, pressure, firmware uye magetsi sesystem imwe chete, saka ma interfaces iwayo anofanira kuiswa mukuburitswa kwekugadzira.

Tsanangurai nzira yekudhinda neenvelopu yemagetsi pamberi pebhodhi guru

PCB yekudhinda inoripirwa nethermal risiti inofanira kugadzirwa yakatenderedza nzira chaiyo, kwete "musoro wethermal" wakajairika. Nzira dzakasiyana muhuwandu hwemadot, kuramba kwemusoro, mapoka estrobe, hunhu hwethermistor, feed-motor winding, cutter load, sensors uye connector pinout. Maprinta ePOS emazuva ano anowanzo shandisa 24 V main rail kunyangwe chikamu chelogic chichishanda nevoltage yakaderera.

Nzira dzekutengesa dzinoratidza kukura kwedambudziko: mashandiro e24 V, kumhanya kwekudhinda kwemazana emamirimita pasekondi, hupenyu hwekudhinda hurefu uye mamiriyoni emitambo yekucheka zvinhu zvinotarisirwa zvakajairika. Saka PCB yekutonga inofanirwa kuita sesystem yesimba rekufamba-nekupwanya, kwete kungochinjisa-ku-kudhinda chete.

Dzora Simba reMusoro weThermal PaDot Pane Kubata Musoro Semutoro Unodzivisa

Rima nehunhu hwekudhinda zvinoenderana nesimba rinopihwa, kunzwisiswa kwepepa, kuramba musoro, nhoroondo yemadot, voltage yekupa uye tembiricha yemusoro. Saka dhizaini yakasimba inobatanidza shanduko yedata/latch ne strobe timing uye thermal compensation. Kutyaira dot rega rega rakumbirwa ne pulse yakafanana patembiricha dzese kunogona kugadzira kudhinda kwakajeka kana kuchitonhora, kupisa zvakanyanya kana kuchipisa kana kupisa kwakanyanya pamifananidzo yakakora.

• Simbisai mepu chaiyo yekubatanidza musoro nemepu yeboka restrobe kubva kumutengesi wemechanism.
• Pima 24 V inodonha zvakanaka mumusoro panguva yekudhinda nhema, kwete chete panguva yekushanda.

Sei nzira yakakwana yekuzviedza isina kukwana?

Nekuti patani imwe chete yemavara echiedza ingasamboshandisa huwandu hwakanyanya hwemagetsi. Kugadzirwa uye DVT zvinofanirwa kusanganisira mifananidzo yakakora, mapatani ebhaibheri/QR uye kutevedzana kwekudhinda kwakasimba kuitira kuti voltage iderere, tembiricha yemusoro uye kutaurirana kwemota/cutter zvionekwe.

Kuparadzanisa Printhead Pulses kubva kuMotor neCutter Noise pa24 V Rail

Musoro, injini yekudyisa uye cheka zvese zvinokwikwidzana kuti pave nesimba rimwe chete mumaprinta akawanda madiki. Ma waveforms avo aripo iye zvino akasiyana: musoro unogadzira ma pulses anodzokororwa, mota inogadzira commutation/step current uye cheka inogona kugadzira mutoro mukuru wenguva pfupi kana stall. Magadzirirwo emagetsi uye kuronga firmware zvinofanirwa kudzivirira mitoro iyi kuti isakonzere MCU reset, Ethernet drop, USB errors kana kusasimba kweprint density.

Gadzira Sensor Harness Inotenderedza Kubata Mapepa, Kwete Mazinga Ekufunga Chete

Maprinta emarisidi anoshandisa pepa rinobuda, rinosvika pamucheto, rinovhura chifukidziro, rinocheka uye dzimwe nguva rinoona mavara matema. Masaini aya anowanzo buda mubhodhi guru kuburikidza netambo dzinochinjika kana waya dziri pedyo nemamota nenzira yepepa. Kuchengetedzwa kweconnector uye ESD/noise tolerance zvinokosha sedunhu re sensor.
