[0002] The priority of the Chinese invention patent application No. 202310974544.7, application name “A consumable chip and consumable box”, and the Chinese invention patent application No. 202311312332.9, application name “A consumable chip and consumable box”, submitted to the China Patent Office on October 11, 2023, are incorporated in the present utility model in their entirety by cross-reference. Technical Field

[0003] The present application relates to the field of printing and imaging, and in particular to a consumable chip and a consumable box. Background Art

[0004] Printing devices, such as printers, copiers, and fax machines, are used to image information onto an imaging medium such as paper using imaging materials such as ink. The imaging process of the printing device requires auxiliary imaging information to complete the imaging process. This auxiliary imaging information is typically recorded on a consumable chip. The consumable chip is removably installed in a consumable cartridge. The consumable cartridge can be an ink cartridge filled with ink or a toner cartridge filled with toner. The ink cartridge and toner serve as the recording materials. The consumable cartridge is removably installed in the printing device.

[0005] When the consumables cartridge is installed in a printing device, the consumables chip in the cartridge establishes an electrical connection with the printing device and performs data communication with the printing device. For example, the consumables chip can be used to control authentication and data matching between the consumables cartridge and the printing device, and to provide imaging-assisted information to the printing device during subsequent imaging processes. Specifically, the consumables chip on the consumables cartridge can be electrically connected to the printing device via corresponding terminals.

[0006] Common consumable chips are equipped with chip select, clock, and data terminals to facilitate data communication with the printer. The chip select and clock terminals of the consumable chip receive chip select and clock signals, respectively, from the printer, while the data terminals receive command information from the printer. Alternatively, the consumable chip can send data to the printer via the data terminals. Typically, a printer can be installed with multiple consumable cartridges, and the printer uses the chip select signal to select the consumable chip it needs to communicate with.

Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0052] The terms used in the embodiments of the present application are for the purpose of describing specific embodiments only and are not intended to limit the present application. The singular forms "a", "an", "the" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise.

[0053] It should be understood that the term "and / or" as used herein simply describes a relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A alone, A and B together, or B alone. Furthermore, the character " / " in this document generally indicates an "or" relationship between the associated objects.

[0054] See also Figure 1a , is a structural diagram of a communication system provided in an embodiment of the present application. Figure 1aAs shown, the communication system includes a host 100 and a chip 200. The host 100 is provided with a communication port 101, and the slave is provided with an interface module 201. A communication link is established between the communication port 101 and the interface module 201. Through the communication link, the host 100 and the chip 200 can transmit information. Specifically, the communication port 101 and the interface module 201 can be electrically connected by means of a stylus, a contact or a spring, so as to establish a communication link. In other embodiments, the communication link can also be a contactless communication link, that is, a wireless communication link. In this case, the communication port 101 and the interface module 201 may include an antenna or a coil for transmitting wireless signals. The host 100 involved in the embodiment of the present application is a device that can perform data processing, control or related operations, and the chip 200 is used to be installed on the host 100 to assist the host 100 in completing related functions.

[0055] In one example, the host may be a computer, and the chip may be a peripheral device / apparatus of the computer. In another example, the host may be a mobile terminal (e.g., a mobile phone, a tablet computer, a PDA (Personal Digital Assistant), etc.), and the chip may be an accessory or peripheral device or apparatus of the mobile terminal, such as a lithium battery chip, a wearable device chip, etc. In some application scenarios, for example Figure 1b Host 100 is a printing device 110, and chip 200 is a consumable chip 210. Printing device 110 is provided with a communication port 112, and consumable chip 210 is provided with an interface module 211. A communication link is established between communication port 112 and interface module 211, enabling information to be transmitted between printing device 110 and consumable chip 210. For example, during the imaging process, consumable chip 210 is used to provide identification information and record material usage status.

[0056] For ease of description, the following describes the technical solutions provided by the embodiments of the present application using the printing device 110 and the consumable chip 210 as examples. However, those skilled in the art will appreciate that, in addition to the printing device 110 and the consumable chip 210, the technical solutions provided by the embodiments of the present application may also be applicable to other types of hosts and chips, and the embodiments of the present application are not limited thereto.

[0057] During the imaging process, the printing device 110 needs the assistance of the imaging auxiliary information of the consumable chip 210 in the consumable box 21 to complete the imaging process. The consumable box 21 can be Figure 2The structure shown. In addition to being recorded in the printing device 110, the imaging auxiliary information of the printing device 110 is also recorded on the consumable chip 210'. The consumable chip 210' here refers to a new model chip whose recycling volume is not yet sufficient. The consumable chip 210' mainly plays the role of identity identification and providing the use status of the recording material. Therefore, when the consumable chip 210' is installed on the printing device 110, the printing device 110 will read the information of the consumable chip 210' and will also send the status and related information of the printing job to the consumable chip 210'. In an embodiment of the present application, the consumable chip 210' is connected to the printing device 110 through electrical contact. For example, the contact pin on the printing device 110 makes electrical contact with the contact part in the consumable chip 210' to achieve a communication connection.

[0058] like Figure 3 As shown, the printing device 110 includes a stylus holder 111, which includes an upper end surface 1111 of the stylus holder 111 in the Y-axis direction, a front end surface 1112 of the stylus holder 111 in the X-axis direction, a first stylus 1113, a second stylus 1114, a third stylus 1115, a fourth stylus 1116, and a fifth stylus 1117. Figure 4 As shown, the consumable chip 210' includes a data terminal 2101, a chip select terminal 2102, a clock terminal 2103, a power terminal 2104, and a ground terminal 2105. Specifically, the first contact pin 1113 of the printing device 110 can contact the data terminal 2101 of the consumable chip 210', the second contact pin 1114 of the printing device 110 can contact the chip select terminal 2102 of the consumable chip 210', the third contact pin 1115 of the printing device 110 can contact the power terminal 2104 of the consumable chip 210', the fourth contact pin 1116 of the printing device 110 can contact the clock terminal 2103 of the consumable chip 210', and the fifth contact pin 1117 of the printing device 110 can contact the ground terminal 2105 of the consumable chip. In this way, the printing device 110 can send a data signal to the consumable chip 210' through the contact between the first contact pin 1113 and the data terminal 2101, the printing device 110 can send a chip select signal to the consumable chip 210' through the contact between the second contact pin 1114 and the chip select terminal 2102, the printing device 110 can send a clock signal to the consumable chip 210' through the contact between the fourth contact pin 1116 and the clock terminal 2103, the printing device 110 can provide an operating voltage to the consumable chip 210' through the contact between the third contact pin 1115 and the power terminal 2104, and the printing device 110 can provide a unified reference low level for the data received and sent between the printing device 110 and the consumable chip 210' through the contact between the fifth contact pin 1117 and the ground terminal 2105, thereby ensuring the correctness and stability of the communication process.

[0059] Based on the concept of environmental protection and recycling, it is often necessary to recycle used consumable chips and replace the old wafers of the consumable chips with wafers that can be used again in the consumable box. However, since the new model consumable chips have just been launched on the market, the recycling volume is not sufficient, while the old model consumable chips have been launched on the market for many years and there is a large amount of recycling inventory. Therefore, the old model consumable chips can be used to convert them into consumable chips that can be used on the printing equipment currently launched on the market.

[0060] See also Figure 5 , is a first chip 210 of the prior art, that is, an old type of consumable chip, the first chip 210 includes a first plane 2101 and a second plane 2102, such as Figure 6 As shown, the second plane 2102 includes a first chip storage module 21021, and the first plane 2101 includes contacts NC1, NC2, RST, SCL, VCC, GND, SDA, A, and B. The shape of the contacts is not limited and can be an irregular wave shape or a rectangle. The contacts RST, SCL, VCC, GND, and SDA are contacts for transmitting signals, which transmit different signals respectively, and therefore are different types of contacts. NC1 and NC2 are short-circuit detection contacts, and A and B are high-voltage contacts for receiving high-voltage signals sent by the printing device 110. The contacts RST, SCL, VCC, GND, and SDA are different types of contacts from NC1 and NC2 and A and B, respectively, so each contact can refer to a first-type contact or a second-type contact, and each type of contact is staggered. The first chip 210 includes a first mounting portion 2106, a second mounting portion 2107, a third mounting portion 2108, and a fourth mounting portion 2109, which are respectively connected to the positioning posts (not shown) of the consumable box. Figure 5 Taking contact NC1 as an example, the area of ​​the contact is divided into three parts: L, M, and N. At least one part of the contact refers to at least one of the three areas; all other contacts can also be divided into three parts: L, M, and N, among which the M area is the area where the printer stylus contacts the contact.

[0061] Example 1

[0062] Figure 7-8 This is a schematic diagram of the adapter chip 310 provided in this application.

[0063] The adapter chip 310 includes a first surface 3101 and a second connection surface 3102. The first surface 3101 includes at least two contact portions. In this embodiment, the first surface 3101 of the adapter chip 310 includes 9 contact portions B1-B9, and the second connection surface 3102 includes 9 connection portions A1-A9. The second connection surface 3102 is a reverse schematic diagram of the first surface 3101, wherein B1 and A1 are the same terminal and can be electrically connected between B1 and A1. Similarly, B2, B3, B4, B5, B6, B7, B8, and B9 correspond to A2, A3, A4, A5, A6, A7, A8, and A9, which are the same terminal. The contact portion and the connection portion are the front and back sides of the same terminal, respectively. Figure 9 As shown, the adapter chip 310 is welded to the first chip 210 to form a consumable chip 410, the contact NC1 contacts A3, the contact RST contacts A9, the contact SCL contacts A2, the contact NC2 contacts A1, the contact A contacts A7, the contact VCC contacts A8, the contact GND contacts A6, the contact SDA contacts A5, and the contact B contacts A4. Figure 8 As shown, A7 is connected to A2 via a wire, A3 is connected to A5 via a wire, and A4 is connected to A6 via a wire. When A2 is soldered to the SCL terminal of the first chip 210, A7 can access the SCL function. Soldering involves printing a certain area of ​​tin on a portion of the connecting portion on the second connection surface 3102 and a portion of the contacts on the first plane 2101 of the first chip 210, and then heating them to connect them. When A5 is soldered to the SDA contact of the first chip 210, A3 can access the SDA function. When A6 is soldered to the GND contact of the first chip 210, A4 can access the GND function. Therefore, the six contacts of the adapter chip and the first chip each have an overlapping area, where the overlapping area is the area M in contact with the contact pins.

[0064] Before the adapter chip 310 is combined with the first chip 210, the first chip storage module 21021 of the first chip 210 needs to be replaced. Figure 10 , switching to a consumable chip 410 memory 4102 that is applicable to a new model of printing equipment, some components can be appropriately added without changing the bonding wires of the first chip 210.

[0065] When the first plane 2101 and the second connection surface 3102 are combined with each other, A8 and the contact VCC of the first plane 2101 , and A9 and the contact RST of the first plane 2101 are exactly in corresponding positions, so there is no need for switching through wires. Therefore, the first method is: A8 can be directly welded to the contact VCC of the first plane 2101, and A9 is directly welded to the contact RST of the first plane 2101; the second method is: A8 is directly welded to the VCC contact of the first plane 2101, and A9 (B9) is a hollow part, so that the second contact pin 1114 of the printing device passes through the adapter chip 310 and directly contacts the contact RST of the first chip 210; the third method is: A9 is directly welded to the contact RST of the first plane 2101, and A8 (B8) is a hollow part, so that the third contact pin 1115 of the printing device passes through the adapter chip 310 and directly contacts the contact VCC of the first chip 210; the fourth method is: A8 (B8) and A9 (B9) are hollow parts, so that the second contact pin 1114 and the third contact pin 1115 of the printing device pass through the adapter chip 310 and directly contact the contact VCC and the contact RST of the first chip 210 respectively. Welding at corresponding positions can ensure the aesthetics of the adapter chip 310 , and hollowing out the contacts can save the material of the adapter chip 310 , each having its own advantages.

[0066] like Figure 9 The adapter chip 310 is combined with the first chip 210 to form a consumable chip 410. B3 on the first surface of the adapter chip 310 obtains the SDA function, B9 obtains the RST function, B7 obtains the SCL function, B8 obtains the VCC function, and B4 obtains the GND function, which respectively contact the first contact pin 1113, the second contact pin 1114, the fourth contact pin 1115, the third contact pin 1116, and the fifth contact pin 1117 of the printing device to establish an electrical connection for communication, thereby realizing communication between the printing device 110 and the consumable chip 410.

[0067] After the consumable chip 410 is installed on the consumable box 21 , it is then installed on the printing device 110 .

[0068] The consumable box and consumable chip of the present application can realize the recycling of a large number of low-value old-model chips and convert them into high-value consumable chips suitable for new-model printing equipment. It is only necessary to produce an adapter chip, and the adapter chip includes simple wires inside, and produce consumable chips 410 memories 4102 suitable for new-model printing equipment. There is no need to design a complex circuit structure for the new-model chip.

[0069] Example 2

[0070] like Figure 11As shown, the adapter chip 310 of this embodiment has a smaller area than that of embodiment 1, which can effectively save production costs. For a specific number of contact pins, the adapter chip 310 includes 4 contact parts, namely B3, B7, B8 and B4. The first groove 3108 and the second groove 3109 respectively coincide with the edges of the third mounting part 2108 and the fourth mounting part 2109 to match the positioning column of the consumable box; the second connecting surface 3102 includes 7 connecting parts, namely A2-A8, and A9 is a hollow part, among which B3 and A3 are different sides of the same terminal, B7 and A7 are different sides of the same terminal, B8 and A8 are different sides of the same terminal, and B4 and A4 are different sides of the same terminal; contact NC1 contacts A3, contact SCL contacts A2, contact A contacts A7, contact VCC contacts A8, contact GND contacts A6, contact SDA contacts A5, and contact B contacts A4, as shown Figure 12 As shown, A7 is connected to A2 through a wire, A3 is connected to A5 through a wire, and A4 is connected to A6 through a wire. When A2 is welded to the SCL of the first chip 210, A7 can obtain the SCL function. When A5 is welded to the contact SDA of the first chip 210, A3 can obtain the SDA function. When A6 is welded to the contact GND of the first chip 210, A4 can obtain the GND function.

[0071] Figure 13 As shown, when the adapter chip 310 is welded to the first chip 210 to form the consumable chip 410, the contact NC2 is exposed, and the second contact pin 1114 passes through the hollow portion B9 of the adapter chip 310 and contacts the contact RST of the first chip 210. B3 on the first surface of the adapter chip 310 obtains the SDA function, B7 obtains the SCL function, B8 obtains the VCC function, and B4 obtains the GND function, which respectively contact the first contact pin 1113, the fourth contact pin 1115, the third contact pin 1116, and the fifth contact pin 1117 of the printing device to establish an electrical communication connection; in some cases, B8 can also be hollow, and the third contact pin 1116 passes through B8 and contacts the contact VCC of the first chip 210, and can also transmit power signals.

[0072] Example 3:

[0073] Figure 14-15 Schematic diagram of the adapter chip 310 provided in this application. The adapter chip 310 includes a first surface 3101 and a second connection surface 3102. In this embodiment, the second connection surface 3102 of the adapter chip 310 includes connection portions 31021 to 31026. Figure 15The second connection surface 3102 is a reverse schematic diagram of the first surface 3101. The connection portion 31021 is connected to the connection portion 31025 via a wire, the connection portion 31022 is connected to the connection portion 31023 via a wire, and the connection portion 31024 is connected to the connection portion 31026 via a wire. The middle position of the adapter chip 310 is hollowed out, so that when the adapter chip 310 is fixed to the first chip 210, all the contacts of the first plane 2101 are exposed, allowing the contact pins on the printing device 110 to contact the contacts of the first plane 2101 of the first chip 210. The six contacts of the adapter chip and the first chip have overlapping areas, and the overlapping areas do not coincide with the areas contacted by the contact pins. At the same time, the adapter chip 310 can also adapt to the first mounting portion 2106 and the second mounting portion 2107 of the first chip 210 without affecting the matching of the first chip 210 with the positioning posts on the consumable box.

[0074] When the connection part 31022 is welded to the SCL of the first chip 210, the connection part 31023 can obtain the signal transmitted by the contact SCL. Welding is to print a certain area of ​​tin at the contact point between the part of the connection part on the second connection surface 3102 and at least a part of the contact part on the first plane 2101 of the first chip 210, and fix the two together by heating to achieve electrical connection. When the connection part 31025 is welded to the contact SDA of the first chip 210, the connection part 31021 can obtain the signal transmitted by the contact SDA. When the connection part 31024 is welded to the contact GND of the first chip 210, the connection part 31026 can obtain the signal transmitted by the contact GND. Since when the first plane 2101 and the second connection surface 3102 are combined with each other, the installation position of the adapter chip 310 just corresponds to the contact VCC and contact RST of the first plane 2101, there is no need to transfer through wires.

[0075] Example 4:

[0076] The middle of the adapter chip 310 is hollowed out. Figure 16 and Figure 14 The difference is that the contacts of the first plane 2101 are not all exposed, but the contacts that do not need to contact the contact pins on the printing device 110 are covered, so that the contact area between the adapter chip 310 and the first chip 210 can be increased, and solder can be applied to the contact NC2 of the first chip 210 to weld it to the corresponding part of the second connection surface 3102 of the adapter chip 310, or the two can be pasted together, so that the adapter chip 310 can be more firmly installed on the first chip 210, and the connection part 31022 is connected to the connection part 31023 through a wire, leaving enough space for the wire, and the large hollow area of ​​the previous embodiment can save material for the adapter chip 310, each having its own advantages.

[0077] Example 5:

[0078] Figure 17 and Figure 14 The difference is that the adapter chip 310 does not adapt to the shape of the first mounting portion 2106 and the second mounting portion 2107 of the first chip 210, but covers the first mounting portion 2106 and the second mounting portion 2107, so that the wires connecting 31021 and 31025 and the wires connecting 31022 and 31023 do not need to be bent to adapt to the mounting portion.

[0079] Before the transfer chip 310 is combined with the first chip 210, Figure 6 The first chip storage module 21021 of the first chip 210 (generally a wafer using a soft package or a hard package) is replaced, which may include removing the old wafer, inserting a new wafer, binding the wafers, packaging the wafers, etc. Figure 19 , switch to the consumable chip storage module 4101 that is suitable for the new model printing equipment.

[0080] like Figure 18 The adapter chip 310 is combined with the first chip 210 to form a consumable chip 410. The contact method between the contact pin and the contact point of this combination is also applicable to Examples 3 and 4. At least a portion of the contact NC1 of the first chip 210 is welded to the connecting portion 31021 of the adapter chip 310, and there is a wire connection between the connecting portion 31021 and 31025, which is equivalent to the connecting portion 31021 being connected to the contact SDA of the first chip 210, thereby obtaining the SDA function. When the first contact pin 1113 contacts NC1, it is equivalent to the electrical connection between the first contact pin 1113 and the contact SDA of the first chip 210.

[0081] At least a portion of the contact SCL of the first chip 210 is welded to the connection part 31022 of the adapter chip 310, and there is a wire connection between the connection parts 31022 and 31023, which is equivalent to the connection part 31023 being connected to the contact SCL of the first chip 210, thereby obtaining the SCL function. When the fourth contact pin 1116 contacts the contact A, it is equivalent to the electrical connection between the fourth contact pin 1116 and the contact SCL of the first chip 210.

[0082] At least a portion of the contact GND of the first chip 210 is welded to the connection part 31024 of the adapter chip 310, and there is a wire connection between the connection parts 31024 and 31026, which is equivalent to the connection part 31026 being connected to the contact GND of the first chip 210, thereby obtaining the GND function. When the fifth contact pin 1117 contacts the contact B, it is equivalent to the electrical connection between the fifth contact pin 1117 and the contact GND of the first chip 210.

[0083] because Figure 4 The new chip and Figure 5 The positions of contacts RST and VCC on the first chip are consistent, so there is no need to reconnect these two contacts. The second contact pin 1114 contacts the contact RST, and the third contact pin 1115 contacts the contact VCC, thereby enabling communication between the printing device 110 and the consumable chip 410. All contacts on the first plane 2101 are exposed, allowing the contact pins on the printing device 110 to contact the contacts on the first plane 2101 of the first chip 210.

[0084] The adapter chip 310 is used to direct the signals generated by the contact pins corresponding to the new chip model to the SDA, SCL, and GND contacts of the first chip 210. This is primarily because the first chip storage module of the first chip 210 is disposed on the second plane 2102. After the first chip is modified, the new storage module also needs to be secured to the second plane 2102. Signal vias exist on the circuit board between the first plane 2101 and the second plane 2102 of the first chip 210, electrically connecting the first chip storage module 21021 to the multiple contacts on the first plane 2101. Therefore, after the new storage module is secured to the second plane 2102, it can be electrically connected to the multiple contacts on the first plane 2101 of the first chip 210 through the existing signal vias on the circuit board, eliminating the need for complex processing such as drilling and rewiring on the circuit board of the first chip 210.

[0085] A resistor is connected in series between contact A and contact B of the first chip 210. To avoid signal interference, the present application also requires cutting off the signal wire between contact A and contact B, or removing the resistor connected in series between the two.

[0086] After the consumable chip 410 is installed on the consumable box 21 , it is then installed on the printing device 110 .

[0087] Example 6:

[0088] like Figure 20 As shown, the adapter chip 310 is roughly in the shape of a square. The adapter chip contacts the first chip in the N and L areas of the contacts. Each contact pin only contacts the M area of ​​the contacts of the first chip 210 and does not contact the adapter chip 310. The adapter chip 310 also includes a bending portion 3100, which includes an adapter chip storage module 31001. The bending portion 3100 can wrap a portion of the first chip 210 and contact the adapter chip 31001. Figure 14-15 The difference of the adapter chip 310 is that Figure 14-15 The adapter chip 310 includes 6 connection parts, does not include a storage module, and needs to be Figure 6The first chip storage module 21021 of the first chip 210 is replaced. The current adapter chip 310 includes five connecting parts, including an adapter chip storage module, and the first chip storage module 21021 of the first chip 210 does not need to be replaced. The welding method of the five connecting parts of the adapter chip 310 is that the connecting part 31021 is welded to the contact NC1, the connecting part 31022 is welded to the contact RST, the connecting part 31023 is welded to the contact A, the connecting part 31024 is welded to the contact VCC, and the connecting part 31025 is welded to the contact B. The adapter chip storage module 31001 can replace the first chip storage module 21021 of the first chip 210, so as to adapt to the new functions of the new model printing device. This method does not require the first chip storage module 21021 of the first chip 210 to be removed, reducing the process of disassembling the old storage module and installing the new storage module. The adapter chip 310 can be produced and processed as a whole in multiple pieces, with high efficiency and yield. Compared with the first chip, which has been divided into independent individuals, it faces the problem of low efficiency and yield during processing. In addition, the adapter chip 310 does not require wires for contact part transfer. Even if the transfer is not performed through wires, the function of the contact part can be changed and adjusted when the adapter chip storage module 31001 is connected to each connection part. For example, when the first contact pin 1113 contacts the contact NC1 of the first chip 210, although the contact NC1 does not have the function of transmitting data, since a part of the contact NC1 is welded to the connection part 31021, and the connection part 31021 is connected to the adapter chip storage module 31001, the adapter chip storage module 31001 can adjust the function of the connection part 31021 to the function of transmitting data.

[0089] Example 7:

[0090] Figure 21 Similar to the sixth embodiment, the only difference is that the shape of the adapter chip 310 is changed into a long strip, and the adapter chip contacts the first chip at the N region and the L region of the contact. Figure 22 This is a front view of the consumable chip 410 formed when the adapter chip 310 is welded to the first chip 210. The connection portion 31021 is welded to a portion of the contact NC1, the connection portion 31022 is welded to a portion of the contact RST, the connection portion 31023 is welded to a portion of the contact A, the connection portion 31024 is welded to a portion of the contact VCC, and the connection portion 31025 is welded to a portion of the contact B. Figure 22When the consumable chip 410 is installed in the printing device 110, the fourth contact pin 1116 contacts the contact A, the first contact pin 1113 contacts the contact NC1, the second contact pin 1114 contacts the contact RST, the fourth contact pin 1116 contacts the contact A, the third contact pin 1115 contacts the contact VCC, and the fifth contact pin 1117 contacts the contact B. Each contact pin only contacts the M area among the contacts of the first chip 210 and does not contact the adapter chip 310.
