Description

Repair chip, regeneration chip, ink horn of regeneration and printer system
Technical field
The present invention relates to imaging consumable chip regeneration field, more particularly to a kind of reparation chip, regeneration chip, ink horn of regeneration And printer system.
Background technology
With expanding economy, the regeneration of discarded print cartridge become " low-carbon, environmental protection, green printing, whole world energy-conservation, The synonym of emission reduction, environmentally friendly trend ".
Existing ink-cases of printers chip includes enabling contact, data contact, address contact and clock contact, and they distinguish Energy line, data wire, address wire and clock line are connected with printer, order from printer is received and simultaneously responds, ink Box chip memory storage by print cartridge used in connection with and configuration information.Original-pack print cartridge manufacturer has reused ink in order to avoid user Most print cartridge, using can not direct reduction print cartridge use information method, for example memory cell using fuse bit come ink Measure information.When the ink of print cartridge is used up, the memory cell on print cartridge can record the status information that ink has exhausted, and make print cartridge It can not be used again.
There is print cartridge manufacturer to develop reparation chip, the chip external world will be repaired print cartridge is resetted with print cartridge former chip, So that printer is when obtaining the ink remaining information of print cartridge, print cartridge feedack reflects the unspent letter of its print cartridge ink Breath.It is existing repair chip typically have the enable contact of quantity identical with the former chip of print cartridge, data contact, address contact and when Clock contact.The corresponding contact that chip is repaired with original chip is electrically connected, while making energy line, data wire, address with printer Line and clock line electrical connection.Chip is repaired to receive from printer life according to the communication protocol between printer and the former chip of print cartridge Information is made, and when printer sends reading data command, the returned data to former chip is modified so that printer is thought The ink of print cartridge does not exhaust, so that print cartridge can continue to be used.Repairing the normal work of chip needs external power source to repair Multiple chip circuit is powered, therefore reparation chip is additionally provided with power contact and earthing contact.Such as Fig. 1, it is necessary to chip being repaired Power contact is electrically connected by former chip with the power line of printer, and the earthing contact for repairing chip is passed through into former chip and printing Being electrically connected to ground for machine, realizes power supply of the printer to reparation chip.
Need all contacts of former chip being electrically connected with repairing chip when repairing print cartridge using above-mentioned restorative procedure Connect, and because former chip and reparation chip volume are small, contact area very little is easy to rosin joint, leakage occur in welding process The problems such as weldering, short circuit.Not only high to the welding process requirement in repair process, welding also needs to check former core one by one after completing Each contact of piece and reparation chip ensures that they electrically connect well.Therefore, connection is needed between former chip and reparation chip Contact is more, needs the number of contacts of welding more on same small circuit board, adds the difficulty of welding；Former chip Need the contact of connection more between chip repairing, weld that big difficulty is bigger, because failure welding causes the print cartridge scrapped It is more；Need the contact of connection more between former chip and reparation chip, the later stage needs the number of contacts checked more, adds The workload of ink box regenerating；The power supply of regeneration chip comes from printer signal, it is necessary to by the power contact and ground of regeneration chip Line contact is connected by aluminum steel or copper cash with PCB or FPC plates, further causes the increase of welding difficulty.Meanwhile, The number of contacts used in repairing between chip and former chip is too many, causes ink horn of regeneration easily to be sent out when machine is installed in progress Raw bad the problems such as（Especially when the chip using FPC plates as substrate is installed, due to the characteristic of FPC plates, easily deform upon and lead Open circuit is caused, causes bad）.Cause the yields of the regeneration production of discarded print cartridge relatively low.
The A of application publication number CN 105398226, the data of publication of application 2016 year 03 month application for a patent for invention of 16 days is disclosed A kind of restorative procedure of ink horn of regeneration, reparation chip and ink horn of regeneration.The reparation chip is wired without the institute of monitoring printer Road, only need monitoring printer makes energy line, data wire, and 0 ~ n-1 root boost lines.So as to reduce and printer and former core The number of contacts of piece electrical connection, and then the welding difficulty and workload during ink box regenerating are simplified, reduced from source The risk that print cartridge is scrapped in repair process.Chip is repaired according to the characteristics of communication protocol between the former chip of print cartridge and printer, Monitored according only to it the, signal characteristic on small number of printer circuit judges the command type that printer is sent, and When judging to draw the order of printer transmission as effective reading data command, according only to its monitoring, small number of printing Signal on machine circuit determines that printer needs the data obtained, and is back to printer by the data wire of printer.The skill Art scheme is to repair the improvement for the program progress for performing restorative procedure on chip to print cartridge to reduce in ink box regenerating production process Need the number of contacts of welding.Therefore, the execution of the technical scheme depends on the renewal to repairing chip software, and needs to repair The program of multiple chip carries out relative complex judgement and logical operation process.
