[0033] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] Reference Figures 1 to 6As shown, an embodiment of the present invention provides a chip assembly 10, which is applied to a chip reading and writing system. The chip reading and writing system includes at least a server 20 and a client 30, wherein:

[0035] Server 20 is responsible for database management, rework-related program control, and other system functions. Server 20 is configured with rework-related programs (scripts, etc.) and other system functions (encryption, logging, background management, etc.). It can store and send and receive data to be burned, release the latest version of software and data, remotely manage and upgrade client software, and interact with client 30 for data.

[0036] The client 30 is used for UI interaction, command and data control. The client 30 includes one or more of a laptop, tablet computer or mobile phone, and is responsible for the human-machine interface, system functions and the transfer of rework data. The client 30 is configured with the rework equipment App software (UI interface, rework functions, account management, etc.). The client 30 can be connected to the server 20 through network transmission.

[0037] The chip assembly 10 includes a preset communication interface 11 and a chip body 12. A communication module is provided in the chip body 12. The communication module is used to connect to the client 30 signal through the preset communication interface 11 to receive the data to be burned transmitted by the client 30. The communication module receives the USB protocol signal transmitted by the preset communication interface 11.

[0038] Furthermore, a DFU (Device Firmware Upgrade) program (upgrade module) is also provided in the chip body 12, which is used for data conversion and processing when the chip firmware is upgraded. The chip component 10 can directly convert and process the data to be burned sent by the client 30, thereby reducing the hardware requirements for the chip reading and writing device. Preferably, the data conversion and processing here can include at least one conversion and processing process of data communication protocol conversion, data encryption and decryption, data calculation, etc.

[0039] In the embodiment provided by the present invention, the preset communication interface 11 can transmit data with the client 30 using the USB protocol through the burning component 40 , or can directly transmit data with the client 30 using the USB protocol.

[0040] Reference Figure 1As shown, when the preset communication interface 11 realizes data transmission with the client 30 using the USB protocol through the burning component 40, the burning component 40 does not contain a single-chip microcomputer and a program, and the workflow for upgrading the chip body 12 is only between the server 20, the client 30 and the chip body 12. The burning component 40 only performs the function of data transmission, and the data transmission and reception control is controlled by the interaction between the client 30 and the chip component 10. There are fewer devices, a simpler circuit, and a lower cost.

[0041] In one feasible embodiment, the preset communication interface 11 of the chip component 10 is a USB interface, and the burning component 40 uses a USB device end to establish a signal connection with the USB interface of the chip component 10. In another feasible embodiment, the preset communication interface 11 of the chip component 10 is a USB burning contact on the chip body 12, and the burning component 40 uses a probe to establish a signal connection with the USB burning contact of the chip component 10. In the printing device, if the printer contact protocol transmits an analog signal, then the chip body 12 will add a USB burning contact. If the printer contact protocol transmits a digital signal, then the USB burning contact and the printer contact are the same. The chip uses the IIC digital protocol when working at the front door, and uses the USB protocol to communicate with the client 30 during upgrading. In an embodiment of the present application, the printer contacts and the USB burning contacts are shared, and the chip automatically identifies whether it is a USB or IIC protocol.

[0042] The burning device 40 includes a USB socket. When the client 30 is inserted through the USB socket, it presents a USB drive letter or a HID device. The data transmission and reception between the client 30 and the chip component 10 can be performed as a USB drive reading and writing files or a HID device such as a mouse and keyboard reading and writing data.

[0043] In the embodiment of the present application, the chip body 12 has its own upgraded data processing function and can directly use the USB protocol to transmit data with the client 30 such as a mobile phone. The burning part 40 is only responsible for electrical connection and does not perform data processing, thereby saving the cost of the microcontroller, minimizing the cost, and greatly reducing the hardware cost of the rework equipment. The test head is easier to mass-produce, with better consistency and stability. There is no need to develop a test head program, and all programs are processed in the background of the client 30 and the server 20.

[0044] Reference Figure 2 As shown, when the preset communication interface 11 directly transmits data with the client 30 using the USB protocol, the preset communication interface 11 of the chip component 10 can be a USB interface, and the preset communication interface 11 can communicate directly with the client 30 via a USB cable. The preset communication interface 11 of the chip component 10 can also be a wireless module. When the chip body 12 is upgraded, the client 30 is directly used to wirelessly upgrade the chip body 12, which saves more materials, reduces equipment costs, and improves user experience.

[0045] In the embodiments provided by the present utility model, Figure 3 as well as Figure 4 As shown, the chip assembly 10 includes a first consumable box 13, a first mounting portion 14 is provided on the first consumable box 13, a chip body 12 is installed in the first mounting portion 14, a preset communication interface 11 is directly or indirectly electrically connected to the chip body 12, the preset communication interface 11 includes a USB interface, a DFU program is provided in the chip body 12, and the communication module in the chip body 12 is respectively connected to the preset communication interface 11 and the DFU program signal. When the preset communication interface 11 receives the client 30 directly or indirectly using the USB protocol signal communication, the DFU program can directly convert and process the upgrade package after receiving the transmitted upgrade package.

[0046] The preset communication interface 11 can communicate with the client 30 directly through a USB cable, or indirectly through the burning component 40. At this time, the burning component 40 only plays a connecting role. Regardless of whether it communicates with the client 30 directly or indirectly, the chip upgrade workflow is only carried out between the server 20, the client 30 and the chip component 10.

[0047] The preset communication interface 11 has a variety of installation positions. Several installation positions of the preset communication interface 11 are listed below for illustration. It is understandable that those skilled in the art can be inspired by this and conceive of more embodiments.

[0048]

First installation position

[0049] In this embodiment, referring to Figure 3 As shown, the preset communication interface 11 is directly connected to the contacts on the chip body 12 and then installed together to the first installation portion 14. Preferably, the preset communication interface 11 is a USB interface, and the chip body 12 is electrically connected to the USB interface.

[0050] The first mounting portion 14 has various structural forms. In one structural form, the first mounting portion 14 is located in an area on the outer wall of the first consumable box 13, and the chip body 12 is directly installed on the outer wall of the first consumable box 13 by embedding, snapping, or bonding. In another structural form, the first mounting portion 14 is a mounting cavity formed by a plurality of side walls, and the chip body 12 is accommodated in the mounting cavity. The side walls of the mounting cavity can resist external impact and provide a certain degree of protection for the chip body 12. These side walls can be formed by being recessed on the outer wall of the first consumable box 13, or they can be protruding from the outer wall of the first consumable box 13.

[0051] When the first mounting portion 14 is a mounting cavity, a communication port 16 can be opened on the first consumable box 13, and the communication port 16 is connected to the first mounting portion 14. After the preset communication interface 11 and the chip body 12 are installed in the first mounting portion 14 by embedding or snapping, the preset communication interface 11 corresponds to the position of the communication port 16, so that the preset communication interface 11 is exposed to the outside through the communication port 16, which facilitates direct or indirect electrical connection between the preset communication interface 11 and the chip end.

[0052]

Second installation position

[0053] Different from the first installation position, the preset communication interface 11 is not installed together with the chip body 12 in the first installation portion 14. Figure 4 As shown, a second mounting portion 15 is provided on the first consumable box 13, and the preset communication interface 11 is installed in the second mounting portion 15. The preset communication interface 11 is electrically connected to the contacts of the chip body 12 through the first connecting portion. The first connecting portion can be a variety of structural forms such as a wire, a flexible circuit board, etc., which are not limited here.

[0054] The second mounting portion 15 has various structural forms. In one structural form, the second mounting portion 15 is located in an area on the outer wall of the first consumable box 13, and the chip body 12 is directly installed on the outer wall of the first consumable box 13 by embedding, snapping, or bonding. In another structural form, the second mounting portion 15 is a mounting cavity formed by a plurality of side walls, and the chip body 12 is accommodated in the mounting cavity. The side walls of the mounting cavity can resist external impact and provide a certain degree of protection for the preset communication interface 11. These side walls can be formed by being recessed on the outer wall of the first consumable box 13, or they can be protruding from the outer wall of the first consumable box 13.

[0055] When the second mounting portion 15 is a mounting cavity, a communication port 16 can be opened on the first consumable box 13, and the communication port 16 is connected to the second mounting portion 15. After the preset communication interface 11 is installed in the second mounting portion 15 by embedding or snapping, the preset communication interface 11 corresponds to the position of the communication port 16, so that the preset communication interface 11 is exposed to the outside through the communication port 16, which facilitates direct or indirect electrical connection between the preset communication interface 11 and the chip end.

[0056]

The third installation position

[0057] In this embodiment, unlike the first installation position and the second installation position, the preset communication interface 11 is detachably installed on the first consumable box 13, and the preset communication interface 11 can be used as an independent component. The preset communication interface 11 has an external module connected to the client 30 signal and an internal module electrically connected to the communication module.

[0058] The external module can be a USB interface, etc., and the internal module can be a contact pin or a spring, etc. Under normal circumstances, the preset communication interface 11 is located at the first mounting part 14 or the second mounting part 15. When data needs to be burned, the preset communication interface 11 can be removed from the first consumable box 13 and inserted into the USB port of the client 30 (mobile phone, tablet or computer). It will present a U disk drive letter or H ID device. The transmission and reception between the client 30 and the chip component 10 can be used as a U disk to read and write files to implement upgrades. The background program of the client 30 can directly interact with the chip body 12 for data, which is more convenient and quick.

[0059]

Fourth installation position

[0060] In this embodiment, the difference from the aforementioned installation position is that the preset communication interface 11 is not provided on the first consumable box 13, but is provided outside the first consumable box 13. Specifically, referring to Figure 5 as well as Figure 6 As shown, the chip assembly 10 also includes a cover body 17, which is provided with an open accommodating cavity. The cover body 17 is detachably covered on at least a portion of the first consumable box 13, and at least a portion of the first consumable box 13 extends from the opening into the accommodating cavity. The first consumable box 13 can be detachably connected to the cover body 17 by snapping. The preset communication interface 11 is provided on the cover body 17 and is arranged corresponding to the chip body 12.

[0061] Reference Figure 5 as well as Figure 6 As shown, the preset communication interface 11 includes a first connecting end 111 and a first USB interface 112 that are electrically connected. The first connecting end 111 is arranged facing the first consumable box 13 and is electrically connected to the contacts on the chip body 12. The first USB interface 112 is arranged facing outward.

[0062] The cover 17 can protect the first consumable box 13. When burning data, the first connection end 111 and the contact of the chip body 12 set on the first consumable box 13 have been abutted. Then, the USB connection line is used to establish a communication connection between the first USB interface 112 and the client 30. The first USB interface 112 transmits the acquired data to the first connection end 111, and then transmits the acquired data to the chip body 12.

[0063] When burning data, the first connection end 111 on the cover body 17 can always abut against the contact of the chip body 12, so there is no need for manual alignment, and automatic alignment is more accurate. There is no need to worry about the first connection end 111 being out of contact with the contact of the chip body 12. The upgrade is more stable, which improves the convenience of customer upgrades. Moreover, the preset communication interface 11 is suitable for mass production in factories, and the USB connection cable can be provided by the user, which is more cost-effective.

[0064] In this embodiment, the first connection terminal 111 can use a probe or a spring, and the first USB interface 112 can be a USB socket, which is not limited here. Specifically, the cover 17 can be the protective cover originally provided on the toner cartridge. To save costs, the pre-installed communication interface 11 is embedded in the protective cover. The protective cover has a built-in USB socket and spring. The spring contacts the chip body 12 tightly and accurately. Using the USB socket for docking, there is no need for manual alignment, freeing up hands, making operation more convenient, avoiding programming failures caused by manual testing jitter, and making upgrades more stable.

[0065]

Fifth installation position

[0066] In this embodiment, the chip assembly 10 also includes a packaging box, and the first consumable box 13 is accommodated in the packaging box. A window is opened on the packaging box, and at least part of the preset communication interface 11 is exposed outside the packaging box through the window. The preset communication interface 11 can be set on the first consumable box 13 or in the packaging box, which is not limited here. The preset communication interface 11 is electrically connected to a second connecting part, and the second connecting part is detachably connected to the chip body 12.

[0067] In one feasible embodiment, a first consumable box 13 is packaged in the packaging box, and a corresponding window is provided on the packaging box. In other feasible embodiments, the packaging box can also be used to package multiple first consumable boxes 13, and a corresponding window is provided on the packaging box for the preset communication interface 11 to leak out. The exposed preset communication interface 11 is electrically connected to the chip body 12 on multiple first consumable boxes 13 at the same time, and can be burned simultaneously or sequentially.

[0068] During rework and upgrade, since the preset communication interface 11 is directly exposed on the packaging box, the operation is more convenient and the alignment is easy, and there is no need to disassemble the packaging box, thereby improving the rework efficiency.

[0069] Preferably, the first connecting part is detachably connected to the chip body 12, for example, by spot welding with a flexible board, or by connecting to the chip body 12 with an incision. With such an arrangement, when the user takes out the first consumable box 13 for use, the first connecting part and the preset communication interface 11 can be removed, which facilitates the installation of the first consumable box 13 on the machine, and there is no need to pre-open a hole in the first consumable box 13 to accommodate the preset communication interface 11.

[0070]

Sixth installation position

[0071] In this embodiment, the prefabricated communication interface 11 and the chip body 12 can be detachably arranged on the first consumable box 13. Specifically, the first mounting portion 14 is a chip rack that can be detachably fixed to the first consumable box 13. The preset communication interface 11 and the chip body 12 are both installed on the chip rack. The preset communication interface 11 is directly connected to the contacts on the chip body 12, or is electrically connected to the contacts of the chip body 12 through the first connecting portion.

[0072] When burning is required, the chip frame can be removed, and the preset communication interface 11 can be directly inserted into the USB port of the client 30 (mobile phone, tablet or computer) via a USB cable. The transmission and reception between the client 30 and the chip component 10 can be used as a USB disk to read and write files to implement the upgrade. The background program of the client 30 can directly interact with the chip body 12 for data. After the upgrade, the chip frame is put back into the first consumable box 13.

[0073]

Seventh installation position

[0074] In this embodiment, the preset communication interface 11 is a wireless module. When the chip assembly 10 is upgraded, the client 30 is directly used to wirelessly upgrade the chip body 12, which saves materials, reduces equipment costs, and improves user experience.
