Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of chip reading and writing, and particularly relates to a chip reading and writing device. BACKGROUND

[0002] A printer is a commonly used office equipment. The printer has consumables such as ink cartridges and developing cartridges. A chip is arranged on the consumable, which is used to store relevant information about the consumable, such as attribute information such as a consumable model, a production date, a manufacturer, a serial number, a chip program version, and the like. With the update of the consumable model and the like, the current program content in the chip needs to be updated, which requires the use of a chip reading and writing device to burn the chip program, that is, to perform a "rework" process on the chip that needs to be upgraded.

[0003] In addition, in order to enable an ink cartridge refilled with ink or a compatible manufacturer's ink cartridge to be normally used on an image forming device main body, it is necessary to restore the ink cartridge or the toner cartridge information to an initial state, in particular, to restore the recorded recording material capacity information recorded in the storage chip to an initial state, including an ink remaining amount or a toner sufficient state, referred to as an image cartridge initial state information, so that the image forming device can meet the requirement of detecting the recorded recording material capacity in the information interaction process, and the ink cartridge or the toner cartridge with the storage chip fixed thereon can be reused. This process is referred to as "resetting" of the chip.

[0004] In the existing rework / resetting device, as described in patent WO2021147861A8, a test head module (probe module) is fixedly arranged on the device main body by screws or welding. Since the contact arrangement and function definition of different ink cartridge chips are different, the existing device can only be applied to specific ink cartridge testing, resulting in poor applicability. SUMMARY

[0005] The present application provides a chip reading and writing device to at least solve the technical problem that the existing chip reading and writing device cannot conveniently replace the test head module.

[0006] In order to achieve the above-mentioned purpose, the present application provides a chip reading and writing device, which comprises a base, a probe module and an ink cartridge positioning mechanism; the base is provided with a quick dismounting structure, and the probe module is detachably mounted on the base through the quick dismounting structure; the ink cartridge positioning mechanism is provided with a to-be-read-and-written ink cartridge, and the ink cartridge positioning mechanism is movably arranged relative to the probe module.

[0007] Further, the ink cartridge positioning mechanism is connected with the base through a moving mechanism, and the moving mechanism drives the to-be-read-and-written ink cartridge mounted on the ink cartridge positioning mechanism to move in the probe extension direction of the probe module.

[0008] Furthermore, the ink cartridge positioning mechanism is also provided with a first locking member and an ink cartridge mounting part. The ink cartridge mounting part is used to install the ink cartridge to be read and written, and the first locking member is used to fix and unlock the ink cartridge mounting part so that the ink cartridge mounting part is detachably connected to the ink cartridge positioning mechanism.

[0009] Furthermore, a second locking member is provided between the ink cartridge positioning mechanism and the base. The second locking member has a locked state and an open state. In the locked state, the ink cartridge positioning mechanism is locked in the ink cartridge test position. In the open state, the ink cartridge positioning mechanism moves in the probe extension direction of the probe module through the moving mechanism.

[0010] Furthermore, it also includes an electrical module, which is detachably mounted on the base via the quick-release structure. The quick-release structure has a fixed state and a relaxed state. In the relaxed state, the electrical module and the probe module are both in a movable state. In the fixed state, the electrical module and the probe module are both in a fixed installation state.

[0011] Furthermore, the quick-release structure has an elastic mechanism and a third locking element. A mating connector is provided between the electrical module and the probe module. The elastic force of the elastic mechanism is greater than the locking force of the mating connector. In the relaxed state, the mating connector is disengaged under the elastic force of the elastic mechanism. In the fixed state, the mating connector is connected under the locking force of the third locking element.

[0012] Furthermore, the quick-release structure also includes a front positioning module and a rear positioning module, which are movably connected by the third locking member. The probe module is positioned on one of the front positioning module and the rear positioning module, and the electrical module is positioned on the other of the front positioning module and the rear positioning module.

[0013] Furthermore, the front positioning module has a probe module cooperating positioning part, and the probe module is provided with a probe module positioning part. The probe module positioning part and the probe module cooperating positioning part are configured to initially position the probe module on the front positioning module; the rear positioning module is also provided with an electrical module cooperating positioning part, and the electrical module positioning part and the electrical module cooperating positioning part are configured to initially position the electrical module on the rear positioning module.

[0014] Furthermore, the quick-release structure includes two opposing sub-positioning modules, with the electrical module and the probe module clamped and positioned between the two sub-positioning modules; wherein the third locking element is disposed on at least one of the sub-positioning modules.

[0015] Furthermore, the third locking member is provided with a locking buckle and a push-pull mechanism. One of the front positioning module or the rear positioning module is provided with a positioning module connector. The locking buckle is connected to the positioning module connector. One end of the push-pull mechanism is connected to the locking buckle, and the other end is connected to the other of the front positioning module or the rear positioning module. The locking buckle pushes and pulls the positioning module connector through the push-pull mechanism, thereby causing the front positioning module and the rear positioning module to move closer to or further away.

[0016] This application provides a chip read / write device that, by setting up a quick-release structure, allows for convenient and rapid replacement of the probe module, thereby improving the applicability of the chip read / write device.

[0033] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0035] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0036] It should be noted that the directional terms such as "upper," "lower," "left," and "right" described in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0037] The chip stores data, and chip read / write devices are used to program or reset data onto the chip. The data stored in the chip may include program data and / or information data. Program data is used to control the chip's internal logic; information data is used to record relevant information about the consumable cartridge.

[0038] Existing chip reading and writing devices include probe modules. Typically, in order to ensure that the probes on the probe module can make good contact with the ink cartridge chip contacts during testing, the probe module is usually fixed to the base using non-removable or difficult-to-remove methods such as screws or welding. This results in the chip reading and writing device being only applicable to a certain type of ink cartridge rework or reset, which is not conducive to the universality of the device.

[0039] Furthermore, current ink cartridge products with printheads have numerous contacts per product, high contact density, and small gaps. Reading and writing devices generally use the original carriage method for rework / reset operations, which can only be performed on a single product, resulting in low efficiency. In addition, the original carriage installation method uses an arc-shaped upward or downward pressure method for the ink cartridge 2, as shown in the embodiment of patent CN201821678092.9. Both installation and removal require manual operation, which involves a large amount of force and is not suitable for long-term operation. Moreover, the arc-shaped upward or downward pressure method for the ink cartridge 2 causes the chip contacts and the carriage test probe to scrape against each other, making the carriage test probe prone to deformation.

[0040] In view of this, this application provides a chip read / write device, such as... Figure 1 As shown, the chip reading and writing device 1 is equipped with an ink cartridge 2 to be read and written. The chip reading and writing device 1 is connected to the control host 4 through the connecting component 3. The connecting component 3 can be a connecting wire, a docking port, or a wireless unit. It is only necessary to achieve a communication connection with the control host 4. The control host 4 controls the chip reading and writing device 1 to read and write the chip storage unit on the ink cartridge 2.

[0041] In one embodiment of this application, such as Figure 2 As shown, the chip reading and writing device 1 includes a base 15 for supporting the main structure. An electrical module 11, a positioning module 12, a probe module 13, and an ink cartridge positioning mechanism 14 are disposed on the base 15. The positioning module 12 is used to install and position the electrical module 11 and the probe module 13. The base 15 is provided with a guide rail mechanism 151 (a moving mechanism, or other movable mechanism, such as a gear rack or pulley) that cooperates with the bottom and side of the ink cartridge positioning mechanism 14. The ink cartridge positioning mechanism 14 is slidably disposed on the base 15 via the guide rail mechanism 151 and is movable relative to the probe module 13. The ink cartridge positioning mechanism 14 can be moved toward the probe extension direction of the probe module via the guide rail mechanism 151, or it can be moved in the direction intersecting the probe extension direction of the probe module 13 by setting an auxiliary guide rail (not shown), thereby adjusting the relative position of the chip contact of the ink cartridge to be read and written installed on the ink cartridge positioning mechanism and the probe of the probe module 13.

[0042] In addition, a second locking member 143 is provided on the ink cartridge positioning mechanism 14. The second locking member 143 is connected to the base and is configured in cooperation with the guide rail mechanism 151. The ink cartridge positioning mechanism 14 slides on the guide rail mechanism 151 toward the probe module 13 and finally locks the second locking member 143, locking the ink cartridge positioning mechanism 14 in the ink cartridge test position (locked state). When the second locking member 143 is opened, the ink cartridge positioning mechanism 14 is pulled / pushed open and moves away from the probe extension direction of the probe module 13 on the guide rail mechanism 151 until the ink cartridge loading and unloading position (open state). In the embodiment of this application, the ink cartridge positioning mechanism 14 in the ink cartridge test position is close to the probe module 13, so that the chip contact 22 on the ink cartridge 2 contacts the probe 1331 on the probe module 13. The ink cartridge positioning mechanism 14 in the ink cartridge loading and unloading position is away from the probe extension direction of the probe module 13, making the ink cartridge 2 easy to install and remove.

[0043] In the embodiments of this application, such as Figures 2-4 As shown, the ink cartridge positioning mechanism 14 is provided with an ink cartridge mounting part 142, which is used to mount the ink cartridge 2; as Figure 3 As shown, a chip 21 is provided on one side of the ink cartridge 2, and chip contacts 22 are provided on the chip 21. The ink cartridge 2 is mounted on the ink cartridge mounting part 142 with the chip mounting surface facing the probe module 13. Under the action of the second locking member 143 and the guide rail mechanism 151, the ink cartridge positioning mechanism 14 can drive the ink cartridge 2 to move towards the probe module 13 in the probe extension direction of the probe module 13, so that the chip contacts 22 on the ink cartridge 2 contact the probes 1331 on the probe module 13, ensuring accurate positioning. Finally, the second locking member 143 locks the ink cartridge positioning mechanism 14 in the ink cartridge test position, as shown. Figure 4 As shown.

[0044] In one embodiment of this application, since the sizes of ink cartridges of different brands and models vary, the ink cartridge mounting part 142 and the ink cartridge positioning mechanism 14 can be separated (detached). The ink cartridge positioning mechanism 14 is also provided with a first locking member 141 for fixing and unlocking the ink cartridge mounting part 142, so that the ink cartridge mounting part 142 and the ink cartridge positioning mechanism 14 can be detachably connected, which facilitates the replacement of the appropriate ink cartridge mounting part 142 according to the ink cartridge brand and model, and ensures its stability during movement.

[0045] Preferably, the first locking member 141 is a tension spring or plunger mechanism and has an unlocking retaining buckle, so that the first locking member 141 can remain in the unlocked state in the replacement ink cartridge mounting part 142.

[0046] In one embodiment of this application, such as Figure 5As shown, a positioning module 12 is supported and installed on the base 15. In the embodiments of this application, the positioning module 12 includes a quick-release structure. The probe module 13 is detachably positioned on the positioning module 12 through the quick-release structure. The quick-release structure of this application includes disassembly and assembly parts that do not require external tools, and can be quickly disassembled and assembled by hand.

[0047] In one embodiment of this application, a fixing part is provided on one of the positioning module 12 and the probe module 13, and a quick-release locking part is provided on the other. Preferably, the quick-release locking part is provided on the probe module 13. Preferably, the quick-release locking part is connected to the fixing part on the positioning module 12 using a self-locking button or a press arm quick-locker, so as to realize the quick assembly and disassembly of the probe module 13 on the positioning module 12.

[0048] In one embodiment of this application, the positioning module 12 includes a rear positioning module 121, a front positioning module 123, and a third locking member 122 (quick-release locking member). At least one of the rear positioning module 121 and the front positioning module 123 is connected and supported on the base 15. Alternatively, the positioning module 12 is further provided with a fixed support member (not shown), which is connected and supported on the base 15. The third locking member 122 is used to connect the rear positioning module 121 and the front positioning module 123.

[0049] In the embodiments of this application, the positioning module 12 has two sub-positioning modules arranged opposite to each other, and the two sub-positioning modules position and clamp the electrical module 11 and the probe module 13 between the two sub-positioning modules; preferably, the positioning components on the two sub-positioning modules are partially or completely mirrored; preferably, the third locking member 122 is disposed on one of the sub-positioning modules.

[0050] like Figure 6 As shown is a partial (view A) enlarged view of the positioning module 12. One end of the third locking member 122 is fixedly connected to the rear positioning module 121, and the other end of the third locking member 122 is fixedly connected to the front positioning module 123. The third locking member 122 has a telescopic mechanism, which allows the rear positioning module 121 and the front positioning module 123 to move relative to or away from each other under the action of the third locking member 122; or, one of them moves relative to or away from the other.

[0051] In the embodiments of this application, the third locking member 122 is provided with a locking buckle 1221, and a front positioning module connector 1222 is provided at one end fixedly connected to the front positioning module 123. The front positioning module connector 1222 is fixed to the card interface 1231 provided on the front positioning module 123. The locking buckle 1221 is connected to the front positioning module connector 1222 through the push-pull mechanism 1223. The locking buckle 1221 pushes and pulls the front positioning module connector 1222 through the push-pull mechanism 1223, thereby causing the front positioning module 123 to move towards or away from the rear positioning module 121.

[0052] In a preferred embodiment of this application, the rear positioning module 121 is provided with an opening 1212 for the passage of the push-pull mechanism 1223. The push-pull mechanism 1223 is connected to the locking buckle 1221 and the front positioning module 123 through the opening 1212. The front positioning module 123 is provided with a card interface 1231 for fixing the front positioning module connector 1222. In other embodiments of this application, the opening 1212 can be omitted, and the push-pull mechanism 1223 can protrude through the edge of the rear positioning module 121. The card interface 1231 can also be omitted, and it can be fixed directly by welding or screws. Examples are not provided here. The embodiments of this application are used to illustrate the connection of the push-pull mechanism 1223 and are not intended to limit the scope.

[0053] In one embodiment of this application, the push-pull mechanism 1223 can be disposed on the side of the front positioning module 123, or on the side of the rear positioning module 121, or on both sides. When the push-pull mechanism 1223 is disposed on one side, the locking buckle 1221 is disposed on the other side. One of the front positioning module 123 and the rear positioning module 122 is fixedly connected to the base 15, and the other moves toward or away from the fixed side. When the push-pull mechanism 1223 is disposed on both sides, the positioning module 12 is also provided with an additional fixed support member. The fixed support member is fixedly connected to the base 15 and provides movable support for the front positioning module 123 and the rear positioning module 121. The locking buckle 1221 drives the push-pull mechanism 1223 to make the front positioning module 123 and the rear positioning module 121 move relative to or away from each other. Preferably, the locking buckle 1221 is disposed in the middle position of the front positioning module 123 and the rear positioning module 121.

[0054] Preferably, the positioning module 122 further includes a spring 1224 and / or a telescopic bearing 1225 disposed between the front positioning module 123 and the rear positioning module 121, so that when the locking buckle 1221 is in the relaxed (open) state, the front positioning module 123 and / or the rear positioning module 121 can automatically move away from each other under the force of the spring 1224 and / or the telescopic bearing 1225.

[0055] In the embodiments of this application, the front positioning module 123 is used to position the probe module 13, and the third locking member 122 is used to adjust the position of the front positioning module 123, so as to move the probe module 13 closer to or away from the electrical module 11. Before removing the probe module 13, the locking buckles 1221 of the sub-positioning modules on both sides are loosened, and the connection between the electrical module 11 and the connector of the electrical module 11 is separated by the force of the spring 1224, so as to facilitate the removal of the probe module 13.

[0056] like Figure 6 and Figure 9As shown, the front positioning module 123 is provided with a probe module mating positioning part 1232 that cooperates with the probe module 13 for positioning, and the probe module 13 is provided with a probe module positioning part 1321. The probe module positioning part 1321 and the probe module mating positioning part 1232 are mated together to initially position the probe module 13 onto the front positioning module 123. Preferably, one of the probe module mating positioning part 1232 and the probe module positioning part 1321 is a groove structure, and the other is a protrusion structure that mates with the groove. Preferably, the protrusion structure is provided on both sides of the non-probe setting surface of the probe module 13.

[0057] In one embodiment of this application, such as Figure 7 As shown, the chip reading and writing device 1 is equipped with an electrical module 11, which includes a housing for providing protection and support to ensure the safety of the internal circuit board; a back cover for protecting the communication circuit board and providing necessary heat dissipation; a communication circuit board consisting of one or more circuit boards working together to be responsible for data transmission and processing; and interfaces with multiple interfaces on the back for connecting to the control host 4 via network cables or other means to achieve data communication.

[0058] Preferably, the electrical module 11 is further provided with a probe interface 111, which is used for electrical connection with the probe module 13. Preferably, the probe interface 111 can be connected to the probe module adapter 134 using a European male or female plug. In the embodiments of this application, other connector structures can also be provided to connect the probe interface 111 to the probe module adapter 134.

[0059] In the embodiments of this application, the electrical module 11 is detachably installed on the base 15 through the quick-release structure of the positioning module 12. The quick-release structure has a fixed state and a relaxed state. In the relaxed state, the electrical module 11 and the probe module 13 are both in a movable state. In the fixed state, the electrical module 11 and the probe module 13 are both in a fixed installation state. This arrangement allows the electrical module and the positioning module of the chip reading and writing device to be disassembled and installed together, which is more convenient.

[0060] In the embodiments of this application, since the connector between the probe interface 111 and the probe module adapter 134 has a certain locking force (connector holding force), when the locking buckle 1221 is opened to take out the electrical module 11 or the probe module 13, the tension of the spring 1224 and / or the telescopic bearing 1225 overcomes the locking force between the probe interface 111 and the probe module adapter 134, and automatically disengages, making the operation more convenient and faster.

[0061] In the embodiments of this application, the elastic force of the spring 1224 is greater than the locking force (retaining force) of the mating connector. In the relaxed state, the connector is disconnected under the elastic force of the spring 1224, and in the fixed state, the connector is connected under the locking force of the locking buckle 1221.

[0062] Preferably, the electrical module 11 is further provided with an electrical module positioning part 112, and the rear positioning module 121 (e.g., at a position away from the rear end of the probe module 13) is further provided with an electrical module mating positioning part 1211, so that the electrical module 11 is initially positioned on the rear positioning module 121. Preferably, one of the electrical module mating positioning part 1211 and the electrical module positioning part 112 is a groove structure, and the other is a protrusion structure that mates with the groove; preferably, the protrusion structure is provided at the tail end of the rear positioning module 121 of the two sub-positioning modules to form a receiving space, which mates with the groove structure of the electrical module positioning part 112 for positioning, so that the receiving space can accommodate or partially accommodate the electrical module 11.

[0063] Preferably, the rear positioning module 121 is further provided with a rotating plunger 1213 or other cooperating positioning part for rotating and locking the electrical module 11 for further positioning.

[0064] Installation method: There are mounting slots on both sides of the outer shell of the electrical module 11, which cooperate with the bosses on the support plate of the positioning module 12. During installation, the positioning module 12 is inserted from top to bottom and then locked by the rotating plungers 1213 on both sides; during removal, the operation is reversed, that is, first loosen the rotating plungers 1213, and then take out the electrical module 11 from bottom to top.

[0065] The modular design facilitates installation and maintenance, reduces equipment downtime, and improves work efficiency. The modular design also makes replacement and maintenance simple and quick. Through this design, electrical module 11 can work efficiently with other modules to ensure the stable operation of the entire read / write system.

[0066] In one embodiment of this application, such as Figure 8a The diagram shown is a disassembled view of the probe module 13. Figure 8B shows the overall structure of the probe module 13, which includes a probe protection plate 131, a probe module fixing frame 132, a probe plate 133, and a probe module adapter 134.

[0067] Probe module mounting frame 132: Provides structural support and protection to ensure the stability of internal components.

[0068] Probe protection plate 131: Protects probe plate 133 from damage when not in operation.

[0069] Probe board 133: Multiple probes 1331 are welded on it to form a probe group for actual read and write operations. The probe group can perform read and write operations on multiple ink cartridges 2 at the same time, thereby significantly improving efficiency.

[0070] Probe module adapter 134: Connects to electrical module 11 and is electrically connected to probe interface 111 to ensure stable data transmission.

[0071] Preferably, the probe plate 133 is equipped with a switch 1332, which can be adjusted according to different product models and has good versatility.

[0072] Preferably, the probe protection plate 131 is provided with a probe through hole 1311, so that the probe 1331 can extend out of the surface of the probe protection plate 131 and contact the chip contact 22 of the ink cartridge 2; the probe protection plate 131 is also provided with a switch through hole, so that the switch 1332 can extend out of the surface of the probe protection plate 131 for easy control.

[0073] Preferably, a probe module positioning part 1321 is provided on the probe module fixing frame 132. The probe module positioning part 1321 is configured in conjunction with the probe module mating positioning part 1232 to initially position the assembled probe module 13 onto the front positioning module 123. Preferably, the probe module positioning part 1321 consists of two mounting ribs on both sides of the probe module fixing frame 132.

[0074] Installation steps:

[0075] Align the probe module positioning part 1321 with the mounting slot of the probe module mating positioning part 1232, and insert it to complete the installation.

[0076] Connection method:

[0077] After installation, push the locking buckles 1221 on both sides of the positioning module 12 backward at the same time. Use the pressure of the clamp to insert the probe module adapter 134 (European male connector) of the probe module 13 into the probe interface 111 (European female connector) of the electrical module 11, thereby realizing the connection.

[0078] Replacement steps:

[0079] First, loosen the locking buckles 1221 on both sides of the positioning module 12, and use the force of the spring 1224 to separate the probe module adapter 134 from the probe interface 111, so that the probe module 13 can be removed.

[0080] In other embodiments, one or more self-locking button quick-lockers can be used to enable quick replacement of the probe module 13.

[0081] In the embodiments of this application, the probe module 13 adopts a modular design, allowing different probe modules 13 to be replaced according to different products. Thus, when the device needs to read or write to different products, only the corresponding probe module 13 needs to be replaced, enhancing the device's versatility.

[0082] This design not only improves the flexibility of the equipment but also simplifies the maintenance and upgrade process, thereby enhancing overall work efficiency.

[0083] The chip reading and writing device 1 provided in this application keeps the ink cartridge 2 and the probe 1331 moving on the same horizontal line, reducing problems such as probe wear, bending and breakage, and ensuring the accuracy and reliability of the test.

[0084] In the embodiments of this application, since the ink cartridge 2 and the probe 1331 remain at the same level during movement, the wear on the probe 1331 when in contact with the ink cartridge 2 is significantly reduced (traditional ink cartridge readers with printheads experience downward and upward movements, scraping the probe 1331, see patent CN201821678092.9). This means that the service life of the probe 1331 is extended, reducing the frequency of probe 1331 replacement and thus lowering maintenance costs; during horizontal movement, the probe 1331 is less susceptible to lateral pressure, reducing the risk of bending and breakage. This improvement allows the probe 1331 to maintain good working condition even after prolonged use, ensuring the continuity of testing; by reducing the high sliding friction between the ink cartridge 2 and the probe 1331, stable contact between the contact 22 and the probe 1331 is ensured. This stable contact helps improve the accuracy of testing, ensures the reliability of data reading and writing, and avoids test failures due to poor contact. Maintaining the same horizontal height during the movement of ink cartridge 2 from the pick-up position to the test position simplifies the operation process, making it more convenient for users to use the device and improving work efficiency.

[0085] The use of various locking components and guide rails reduces labor intensity, is suitable for long-term operation, and improves user experience.

[0086] This module's design makes positioning operations more flexible, efficient, and user-friendly, improving the overall performance of the device.

[0087] In one embodiment of this application, one or more ball bearing structures can be used to limit the movement between the cartridge positioning mechanism 14 and the base 15, thereby increasing the stability and accuracy of the movement.
