Description
Technical Field
The invention relates to the field of printing and imaging, in particular to a method for repairing a regenerative ink box, a repairing chip and the regenerative ink box.
Background
Existing printer cartridge chips include enable, data, address and clock contacts that communicate with enable, data, address and clock lines, respectively, of the printer, receive commands from the printer and respond, with the cartridge chip storing information relating to the use and configuration of the cartridge. In order to avoid that users repeatedly use the ink cartridge with the exhausted ink, original cartridge manufacturers adopt a method that the use information of the ink cartridge cannot be directly reset, for example, a storage unit adopts a fuse bit to record the ink quantity information. When the ink in the ink box is used up, the storage unit on the ink box can record the state information that the ink is used up, so that the ink box can not be used any more.
Some ink box manufacturers develop a repair chip, and reset the ink box with the original chip of the ink box and the outside of the repair chip, so that when the printer acquires the ink residual information of the ink box, the information fed back by the ink box reflects the information that the ink of the ink box is not exhausted. Existing repair chips typically have the same number of enable, data, address and clock contacts as the cartridge original chip. As shown in fig. 1, the repair chip is electrically connected to the corresponding contacts of the original chip, and is also electrically connected to the enable line, the data line, the address line, and the clock line of the printer. The repairing chip receives command information from the printer according to a communication protocol between the printer and the original chip of the ink box, and when the printer sends a read data command, the returning data of the original chip is modified, so that the printer considers that the ink of the ink box is not exhausted, and the ink box can be continuously used. When the ink box is repaired by adopting the repairing method, all contacts of the original chip are required to be electrically connected with the repaired chip, and due to the small volumes of the original chip and the repaired chip, the problems of insufficient soldering, missing soldering, short circuit and the like are easy to occur in the welding process due to the small contact areas. The requirement on the welding process in the repair process is high, and after the welding is finished, all contacts of the original chip and the repaired chip need to be checked one by one to ensure that the electric connection is good. Therefore, the more contacts which need to be connected between the original chip and the repair chip are, the more contacts which need to be welded on the same tiny circuit board are, and the welding difficulty is increased; the more contacts needed to be connected between the original chip and the repaired chip are, the greater the welding difficulty is, and the more scrapped ink boxes are caused by poor welding; the more contacts needing to be connected between the original chip and the repaired chip, the more contacts needing to be checked in the later period, and the workload of ink box regeneration is increased.
Chinese patent application No. 201520073875.4 discloses a repair chip, an ink cartridge and a printer, the repair chip including: the substrate is provided with a front surface and a back surface; a hollowed-out portion disposed substantially and at a position corresponding to a position of a nozzle control contact of a flexible circuit board of the ink cartridge (i.e., an original chip of the ink cartridge); the memory unit contact is arranged on the front surface of the substrate and is electrically connected with the memory unit of the repair chip; the signals can pass through the contacts and are arranged on the front surface and the back surface of the substrate, and the signals corresponding to the positions on the front surface and the back surface can pass through the contacts to be connected and communicated with each other. The utility model discloses a when repairing the chip and installing on the flexible circuit board of ink horn, can ensure that the position of repairing the chip installation is accurate, reduce to a certain extent and repair the short circuit risk that arouses when chip electric connection is to the flexible circuit board of ink horn, improved the yield of regeneration ink horn. However, when the number of contacts to be welded is still large, a large part of the product is still discarded due to short circuit.

The ink box is arranged on the printer, a clock contact of an original chip of the ink box is electrically connected with a clock line of the printer, an enabling contact of the original chip is electrically connected with an enabling line of the printer, a data contact of the original chip is electrically connected with a data line of the printer, and m address contacts of the original chip are respectively and correspondingly electrically connected with m address lines of the printer one to one. As shown in FIG. 1, the DATA communication between the ink cartridge and the printer is performed in a serial communication mode, in which a clock line CLK, an enable line LOAD, and a DATA line DATA are shared, and address lines ADD1 to ADDm are used separately. Each address line corresponds to a block address of the original chip. Since the internal part of the original chip of the ink box has no crystal oscillator, the clock signal transmitted by an external printer is used as a sampling clock, and the address lines are respectively sampled at the rising edge and the falling edge of the clock. FIG. 2 shows valid read data commands sent by the printer: only one address line (ADD 1) has a high-low level change, and the rest address lines (ADD 2-ADDm) are kept at a low level. At this time, the printer selects the block address corresponding to the address line ADD1, and the repair chip samples and decodes the signal appearing on the address line ADD 1. When an enable signal is asserted on the enable line, DATA corresponding to the address value sampled and decoded from the block address corresponding to the address line ADD1 is returned to the printer via the DATA line DATA.
Therefore, when the printer sends a valid read data command, the signal line CLK, the address line ADD1-m, and the enable line LOAD are all combined. By utilizing the correlation characteristics among certain signal lines of the printer in the communication process, whether the command of the printer is a valid read data command or not is judged correctly, the current memory address to be operated is automatically confirmed, and corresponding repair data is taken out from the corresponding memory address and returned to the printer through the data line of the printer.

The judging method of the command type of the printer by the command judging unit is as shown in FIG. 6: if at most one address contact in the m-1 address contacts monitors that a signal exists on a corresponding address line, judging that a command sent by the printer is a valid data reading command; otherwise, it is determined that the command sent by the printer is not a valid read data command.
The data return device is electrically connected with the command judgment unit, the data return device is electrically connected with the address judgment device, and when the command judgment unit judges that the command sent by the printer is a valid read data command, the address judgment device determines the address block where the repair data needing to be returned is located:
the address block memory stores the one-to-one correspondence between the printer address lines and the address blocks. If the address contact does not monitor a signal on m-1 address lines of the printer, the address judgment device judges that an address block where the repair data needing to be returned is located is an address block corresponding to the address line which is not monitored by the repair chip in the address block memory; if the address contact monitors that m-1 address lines of the printer have signals and only 1 address line has signals, the address judgment device judges that the address block where the repair data needing to be returned is located is as follows: and the address block memory is used for storing address blocks corresponding to the address lines with signals.
The data sending unit searches the corresponding address block for the repair data stored in the address corresponding to the ID value (data index value), and sends the repair data through the data contact and transmits the repair data to the printer through the data line of the printer. The information indicating the remaining ink amount of the ink cartridge obtained by the printer is made not to be 0, i.e., the printer is made to consider that the ink in the ink cartridge is not depleted.
Subsequently, the comparator compares the ID value (data index value) with the IDmax value (data index maximum value) of the corresponding address block:
if ID < IDmax, the counter increments the ID value by 1;
if ID > = IDmax, the counter sets the ID value to an initial value of 0.
In addition, if the command judging means judges that the command transmitted from the printer is not a valid read data command, the counter sets the ID value to an initial value of 0.

Therefore, the repair chip sets the first valid enable signal determination means. The first effective enabling signal judging device is electrically connected with the enabling contact so as to judge whether the effective enabling signal is the first effective enabling signal or not when the enabling contact monitors that the effective enabling signal appears on the printer enabling line.

Subsequently, the repair chip sets the Flag value in the storage device to false; the counter performs an addition 1 process on the ID value so that ID = ID + 1; the timer restarts counting.
The command judging device is electrically connected with the first effective enabling signal judging device, and when the first effective enabling signal judging device judges that the effective enabling signal monitored by the enabling contact is the first effective enabling signal, the command judging device judges whether a command sent by the printer is a valid data reading command:
