Description

Technical Field

[0001] This application belongs to the field of printing technology, specifically relating to a code writing and reading device component and printing consumables. Background Technology

[0002] In the printer industry, the consumable body is fixed inside the printer, and the chip is fixed on the consumable body. The chip's data needs to be upgraded and updated periodically. To facilitate this upgrade, a dedicated code writer / reader device is designed. Specifically, when upgrading the chip's data, the operator holds the code writer / reader device and makes contact between the device's spring and the contacts on the chip. This establishes an electrical connection, allowing the data to be transferred from the code writer / reader device to the chip, thus completing the upgrade.

[0003] However, since data transmission takes time, chip data upgrades also take time. During this time, operators need to hold the code writer / reader device and remove it only after the data transmission is complete. This can easily lead to operator fatigue. Furthermore, if the operator holds the device incorrectly or shakes their hand, the pins of the code writer / reader device may separate from the contacts on the chip, resulting in data upgrade failure. Utility Model Content

[0004] The purpose of this application is to provide a code writing and reading device component and printing consumables, which can solve the problems in related technologies where fixing the code writing and reading device by hand can easily cause operator fatigue and cause chip data upgrade and update failures.

[0005] In a first aspect, embodiments of this application provide a code-writing device component for reading and writing data on chips used in printing consumables, including:

[0006] A code writing and reading device, comprising a device body and a spring pin connected to the device body;

[0007] A positioning bracket for detachably connecting to the printing consumables, the positioning bracket having a fixing groove into which a portion of the main body of the device is embedded;

[0008] The device body and the wall of the fixing groove can be limited and fitted in the direction from the spring needle to the device body, so that the spring needle can be electrically connected to the contacts on the chip of the printing consumable.

[0009] Secondly, this application embodiment also provides a printing consumable adapted to the above-mentioned code writing and reading device component. The printing consumable includes a consumable body, a chip, and a chip holder. The chip is disposed on the chip holder, and the chip holder is connected to the consumable body. The positioning bracket of the code writing and reading device component is detachably connected to the chip holder, so that the spring pin of the code writing and reading device is electrically connected to the contacts on the chip of the printing consumable.

[0010] In this embodiment, a portion of the device body is embedded in the fixing groove of the positioning bracket. The connection between the code writing / reading device and the positioning bracket is achieved through a limiting engagement between the device body and the groove wall in the direction from the spring pin to the device body. Since the positioning bracket is connected to the printing consumables, the code writing / reading device can be fixed to the printing consumables, eliminating the need for the operator to hold the device. Furthermore, the limiting engagement between the device body and the groove wall in the direction from the spring pin to the device body ensures good contact between the spring pin and the chip, guaranteeing stable data transmission and enabling data upgrades and updates to the chip. This design frees the operator's hands, and the code writing / reading device is less susceptible to external interference that could cause it to separate from the chip's contacts, thus ensuring the stability and integrity of data transmission and improving the success rate of data upgrades and updates.

[0039] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0040] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0041] The following description, in conjunction with the accompanying drawings, details the code writing and reading device components and printing consumables provided in the embodiments of this application through specific implementations and application scenarios.

[0042] refer to Figures 1-17 This application provides a code writing and reading device component for reading and writing data of the chip 500 of printing consumables. That is, the code writing and reading device component can be used to upgrade and update the data of the chip 500 of printing consumables.

[0043] The code writing and reading device assembly may include a code writing and reading device 100 and a positioning bracket 200. The code writing and reading device 100 may include a device body 110 and a spring pin 120 connected to the device body 110. The positioning bracket 200 can be used to detachably connect to printing consumables. The positioning bracket 200 may be provided with a fixing groove 210, and a part of the device body 110 may be embedded in the fixing groove 210.

[0044] The device body 110 and the groove wall of the fixing groove 210 can be mutually restrained in the direction from the spring pin 120 to the device body 110, so that the spring pin 120 can be electrically connected to the contact 510 on the chip 500 of the printing consumable. This setting can fix the device body 110 to the positioning bracket 200. Since the positioning bracket 200 is connected to the printing consumable, the code writing and reading device 100 can be fixed on the printing consumable, so that the operator does not need to hold the code writing and reading device 100. At the same time, it can maintain good contact between the spring pin 120 and the chip 500, thereby ensuring the stability of data transmission and enabling data upgrades and updates to the chip 500.

[0045] In the above embodiments, the groove wall of the fixing groove 210 can limit and support the main body 110 of the device, which can prevent the main body 110 of the device from tilting or shifting, thereby improving the stability of the connection between the code writing and reading device 100 and the positioning bracket 200, avoiding interruption of the upgrade process, and eliminating the need for manual assistance in fixing, thus improving upgrade efficiency and ease of use.

[0046] It should be noted that the main body 110 of the device may be equipped with a code writing and reading module, which is electrically connected to the spring pin 120 to upgrade and update the data of the chip 500 through the spring pin 120.

[0047] In an optional embodiment, at least one slot 112 may be provided on one of the first side wall of the device body 110 and the groove wall of the fixing groove 210, and at least one engaging part 211 may be provided on the other. The engaging part 211 can engage with the slot 112 so that the device body 110 and the groove wall of the fixing groove 210 are in upper limit engagement in the direction from the spring pin 120 to the device body 110.

[0048] Optionally, the device body 110 may be provided with a connecting part 111, which can be embedded in the fixing groove 210 to connect the device body 110 and the fixing groove 210. The slot 112 may be provided on the connecting part 111, and the snap-fit ​​part 211 may be provided on the groove wall of the fixing groove 210.

[0049] In this embodiment, by embedding a portion of the device body 110 into the fixing groove 210 of the positioning bracket 200 (for example, embedding the connecting part 111 into the fixing groove 210), and by engaging the snap-fit ​​part 211 with the slot 112, the writing and reading device 100 can be connected to the positioning bracket 200. Since the positioning bracket 200 is connected to the printing consumables, the writing and reading device 100 can be fixed on the printing consumables, thus eliminating the need for the operator to hold the writing and reading device 100. In addition, when the snap-fit ​​part 211 is engaged with the slot 112, the spring pin 120 can be in a compressed state, allowing the spring pin 120 to fully contact the contact 510 on the chip 500. At this time, the spring pin 120 can maintain good contact with the chip 500, thereby ensuring the stability of data transmission and enabling data upgrades and updates to the chip 500. This setup frees up the operator's hands, and the status of the code reader 100 is less susceptible to external interference and separation from the contact 510 of the chip 500, thus ensuring the stability and integrity of data transmission and improving the success rate of data upgrades and updates.

[0050] In other embodiments, the device body 110 and the groove wall of the fixing groove 210 can be connected by fasteners such as screws, so that the device body 110 and the groove wall of the fixing groove 210 are in upper limit engagement in the direction from the spring pin 120 to the device body 110.

[0051] The limiting engagement between the device body 110 and the wall of the fixing groove 210 in the direction from the spring pin 120 to the device body 110 is achieved by the snap-fitting part 211 and the slot 112. Compared with the limiting engagement between the device body 110 and the wall of the fixing groove 210 in the direction from the spring pin 120 to the device body 110 achieved by fasteners such as screws, when disassembling and assembling the device body 110 and the positioning bracket 200, the operator only needs to insert the device body 110 into the fixing groove 210 or pull the device body 110 out of the fixing groove 210. The operation is simple and convenient and does not require the use of other tools.

[0052] Optionally, at least two slots 112 may be provided on the first side wall of the device body 110, including a first slot 1121 and a second slot 1122. The first slot 1121 and the second slot 1122 may be located on opposite sides of the device body 110. It should be noted that the first side wall of the device body 110 includes two opposite side walls of the device body 110. Furthermore, at least two engaging portions 211 may be correspondingly provided on the groove wall of the fixing groove 210, including a first engaging portion 2111 and a second engaging portion 2112. The first engaging portion 2111 can engage with the first slot 1121, and the second engaging portion 2112 can engage with the second slot 1122. This configuration allows for the connection between the two opposite sides of the equipment body 110 and the wall of the fixing groove 210, which helps to improve the connection strength between the equipment body 110 and the positioning bracket 200, and ensures that the equipment body 110 and the positioning bracket 200 are in equilibrium under force, thereby helping to extend the service life of the equipment body 110 and the positioning bracket 200.

[0053] In an optional embodiment, one of a first positioning groove 113 and a positioning part 212 may be provided on the second sidewall of the device body 110 adjacent to the first sidewall, and the other of the first positioning groove 113 and the positioning part 212 may be correspondingly provided on the groove wall of the fixing groove 210, and the positioning part 212 may be embedded in the first positioning groove 113. With this configuration, when connecting the code writing / reading device 100 to the positioning bracket 200, it is not necessary to identify the orientation of the code writing / reading device 100; simply aligning the first positioning groove 113 and the positioning part 212 is sufficient, thereby preventing the code writing / reading device 100 from failing to connect to the chip 500 due to incorrect insertion. Here, one of the first positioning groove 113 and the positioning part 212 may also be provided on the first sidewall of the device body 110, i.e., adjacent to the card slot 112 or the card engaging part 211, and the other of the first positioning groove 113 and the positioning part 212 may be correspondingly provided on the groove wall of the fixing groove 210.

[0054] In this embodiment, a first positioning groove 113 may be provided on the second side wall of the device body 110. Specifically, the first positioning groove 113 may be provided on the connecting part 111 mentioned above, and a positioning part 212 may be provided on the groove wall of the fixing groove 210.

[0055] In optional embodiments of this application, such as Figure 10As shown, a fixing plate 220 can be disposed within the fixing groove 210. The fixing plate 220 can have a positioning through hole 221, which can correspond to the spring pin 120. The spring pin 120 can pass through the positioning through hole 221 and electrically connect to the contact 510 of the chip 500. Furthermore, in the radial direction of the spring pin 120, the spring pin 120 can be limited and engaged with the wall of the positioning through hole 221. This configuration allows the positioning through hole 221 to limit the movement of the spring pin 120, preventing it from tilting and ensuring that the spring pin 120 accurately contacts the contact 510 on the chip 500. It also makes the connection between the code writing / reading device 100 and the positioning bracket 200 more reliable.

[0056] Optionally, the code writing and reading device 100 may include a plurality of spring pins 120. The number of spring pins 120 may be consistent with the number of contacts 510 on the chip 500, and the plurality of spring pins 120 may correspond one-to-one with the plurality of contacts 510 on the chip 500.

[0057] In this embodiment, the fixing plate 220 may be provided with multiple positioning through holes 221, which can correspond one-to-one with multiple contacts 510 on the chip 500. In this way, the multiple positioning through holes 221 can respectively limit the multiple spring pins 120 to ensure that each spring pin 120 can accurately contact each contact 510 on the chip 500. In addition, the positioning through holes 221 on the fixing plate 220 can also serve as weight-reducing holes to reduce the weight of the positioning bracket 200.

[0058] In another alternative embodiment, the positioning bracket 200 is provided with a first elastic arm 230 and a second elastic arm 240, and a clamping space is formed between the first elastic arm 230 and the second elastic arm 240; the chip fixing seat 400 of the printing consumable includes a first chip limiting plate 421 and a second chip limiting plate 422 disposed opposite to each other. When the spring pin 120 is electrically connected to the contact 510 on the chip 500 of the printing consumable, the first chip limiting plate 421 and the second chip limiting plate 422 are limited within the clamping space.

[0059] This design allows for a detachable connection between the positioning bracket 200 and the chip holder 400, and facilitates the installation and removal of the positioning bracket 200. Specifically, when installing the positioning bracket 200, simply press it down to embed the first chip limiting plate 421 and the second chip limiting plate 422 into the clamping space to connect the positioning bracket 200 to the chip holder 400. When removing the positioning bracket 200, simply pull it up to disengage the first chip limiting plate 421 and the second chip limiting plate 422 from the clamping space to separate the positioning bracket 200 from the chip holder 400. The operation is simple and convenient.

[0060] Of course, the positioning bracket 200 can also be connected to the chip holder 400 by fixing screws or the like.

[0061] In this embodiment, the chip holder 400 may further include a frame 410, with the first chip limiting plate 421 and the second chip limiting plate 422 both disposed on the frame 410, and an installation space may be formed between the first chip limiting plate 421 and the second chip limiting plate 422, with the chip 500 disposed in the installation space so that the chip 500 can be detachably disposed on the chip holder 400.

[0062] To prevent chip 500 from detaching from the mounting space, such as Figure 14 As shown, at least one of the first chip limiting plate 421 and the second chip limiting plate 422 has a chip limiting part 424 at its end opposite to the frame 410. Along the direction from the spring pin 120 to the device body 110, the chip 500 can be limited and engaged with the chip limiting part 424. This improves the stability of the chip 500.

[0063] In an optional embodiment, at least one of the first chip limiting plate 421 and the second chip limiting plate 422 may be provided with a first limiting part 423, and at least one of the first elastic arm 230 and the second elastic arm 240 may be provided with a corresponding second limiting part 250. In the direction from the spring needle 120 to the device body 110, the second limiting part 250 may cooperate with the first limiting part 423 for limiting.

[0064] This configuration prevents the positioning bracket 200 from separating from the chip holder 400 in the direction from the spring pin 120 to the device body 110, thereby improving the stability of the connection between the positioning bracket 200 and the chip holder 400. At the same time, through the limiting cooperation of the second limiting part 250 and the first limiting part 423, the spring pin 120 of the code writing and reading device 100 can be kept in a compressed state and in close contact with the contact 510 on the chip 500, thereby improving the electrical conductivity between the code writing and reading device 100 and the chip 500.

[0065] Optionally, in order to further improve the stability of the connection between the positioning bracket 200 and the chip holder 400 and to ensure the force balance between the positioning bracket 200 and the chip holder 400, a first limiting part 423 can be provided on both the first chip limiting plate 421 and the second chip limiting plate 422, and a second limiting part 250 can be provided on both the first elastic arm 230 and the second elastic arm 240. In the direction from the spring pin 120 to the device body 110, each second limiting part 250 can respectively cooperate with each first limiting part 423 for limiting.

[0066] Optionally, both the first elastic arm 230 and the second elastic arm 240 are located within the fixing groove 210, and both are connected to the fixing plate 220. The positioning through hole 221 is located between the first elastic arm 230 and the second elastic arm 240, thus making it easier for the spring pin 120 to contact the contact 510 on the chip 500. Both the first elastic arm 230 and the second elastic arm 240 are spaced apart from the groove wall of the fixing groove 210. This allows the first elastic arm 230 and the second elastic arm 240 to be elastic and have room for deformation.

[0067] In an optional embodiment, the chip holder 400 of the printing consumable may be provided with a positioning rib 430, and a second positioning groove 213 may be provided on the groove wall of the fixing groove 210 corresponding to the positioning rib 430, the second positioning groove 213 for the positioning rib 430 to be embedded therein. Along the extending direction of the consumable body 300 of the printing consumable, the second positioning groove 213 can cooperate with the positioning rib 430 for limiting.

[0068] With this configuration, the second positioning groove 213, in conjunction with the positioning rib 430, can position the positioning bracket 200, thereby enabling the spring pin 120 to accurately align with the contact 510 on the chip 500 and make contact with the contact 510 on the chip 500. Furthermore, the positioning rib 430 can also limit the positioning bracket 200 to prevent it from moving in the extension direction of the consumable body 300, which would cause the spring pin 120 to separate from the contact 510 on the chip 500, thereby improving the stability of the electrical connection between the code writing / reading device 100 and the chip 500.

[0069] Optionally, such as Figure 17 As shown, the second positioning groove 213 can be a notch formed in the groove wall of the fixing groove 210. The notch can include a first region 2131 and a second region 2132 that are connected to each other. The second region 2132 can be located at the edge of the groove wall, and the first region 2131 can be located on the side of the second region 2132 closer to the device body 110. Furthermore, the opening area of ​​the second region 2132 gradually decreases along the direction from the edge of the groove wall to the device body 110. This arrangement facilitates the embedding of the positioning rib 430 into the second positioning groove 213, thereby facilitating the installation of the positioning bracket 200 on the chip holder 400.

[0070] Of course, the second positioning groove 213 may also include only the first region 2131, that is, the opening area of ​​the second positioning groove 213 remains unchanged along the edge of the groove wall to the main body of the equipment 110.

[0071] Optionally, the positioning rib 430 includes at least a first positioning rib 431 and a second positioning rib 432. It should be noted that the number of positioning ribs 430 is at least two, including at least a first positioning rib 431 and a second positioning rib 432. The first positioning rib 431 may be located on the side of the first chip limiting plate 421 opposite to the chip 500, and a first gap 440 may be provided between the first positioning rib 431 and the first chip limiting plate 421. The second positioning rib 432 may be located on the side of the second chip limiting plate 422 opposite to the chip 500, and a second gap 450 may be provided between the second positioning rib 432 and the second chip limiting plate 422.

[0072] When the spring needle 120 is electrically connected to the contact 510 on the chip 500 of the printing consumable, the first elastic arm 230 extends into the first gap 440 and the second elastic arm 240 extends into the second gap 450, so that the first limiting part 423 and the second limiting part 250 are limited and engaged.

[0073] With this configuration, the first positioning rib 431 and the first chip limiting plate 421 can limit the first elastic arm 230, and the second positioning rib 432 and the second chip limiting plate 422 can limit the second elastic arm 240. This can prevent the first elastic arm 230 and the second elastic arm 240 from deforming too much and failing to clamp the first chip limiting plate 421 and the second chip limiting plate 422, and prevent the second limiting part 250 from being unable to cooperate with the first limiting part 423 for limiting. This can further improve the connection stability between the positioning bracket 200 and the chip fixing seat 400.

[0074] In an optional embodiment, a first clearance groove 231 may be provided on the side of the first elastic arm 230 opposite to the second elastic arm 240. When the first elastic arm 230 extends into the first gap 440, the end of the first positioning rib 431 near the first chip limiting plate 421 is embedded in the first clearance groove 231. This can prevent the first elastic arm 230 from interfering when it extends into the first gap 440, facilitating installation. In addition, the first clearance groove 231 and the first positioning rib 431 cooperate to limit the first elastic arm 230, so as to prevent the first elastic arm 230 from moving in the extension direction of the consumable body 300 under force, causing the second limiting part 250 to separate from the first limiting part 423. Furthermore, the first positioning rib 431 can also prevent the first elastic arm 230 from deforming in the direction away from the first chip limiting plate 421.

[0075] A second clearance groove 241 can be provided on the side of the second elastic arm 240 away from the first elastic arm 230. When the second elastic arm extends into the second gap 450, the end of the second positioning rib 432 near the second chip limiting plate 422 can be embedded in the second clearance groove 241. Similarly, this can prevent the second elastic arm 240 from interfering when it extends into the second gap 450, facilitating installation. In addition, the second clearance groove 241 and the second positioning rib 432 can cooperate to limit the second elastic arm 240, so as to prevent the second elastic arm 240 from moving in the extension direction of the consumable body 300 under force, causing the second limiting part 250 to separate from the first limiting part 423. Furthermore, the second positioning rib 432 can also prevent the second elastic arm 240 from deforming in the direction away from the second chip limiting plate 422.

[0076] Based on the code writing / reading device component provided in this application embodiment, this application embodiment also provides a printing consumable, which can be adapted to the code writing / reading device component described in any of the above embodiments. The printing consumable may include a consumable body 300, a chip 500, and a chip holder 400. The chip 500 may be disposed on the chip holder 400, and the chip holder 400 may be connected to the consumable body 300. The positioning bracket 200 of the code writing / reading device component may be detachably connected to the chip holder 400, so that the spring pin 120 of the code writing / reading device 100 is electrically connected to the contact 510 on the chip 500 of the printing consumable.

[0077] The beneficial effects achieved by the printing consumables provided in this application embodiment are consistent with the beneficial effects achieved by the code writing and reading device component provided in this application embodiment, so they will not be repeated here.

[0078] Optionally, such as Figure 16 As shown, the consumable body 300 may be provided with a mounting groove 310, and at least a portion of the frame 410 may be embedded in the mounting groove 310. Furthermore, one of the frame 410 and the consumable body 300 may be provided with a limiting protrusion 311, and the other may be provided with a limiting hole 411. The limiting protrusion 311 can extend into the limiting hole 411 and engage with it, thus enabling a detachable connection between the frame 410 and the consumable body 300. In this embodiment, the consumable body 300 may be provided with at least two limiting protrusions 311, and the frame 410 may be provided with at least two limiting holes 411. Each limiting protrusion 311 can extend into its respective limiting hole 411, and the limiting hole 411 can extend along the extending direction of the consumable body 300. Here, the shapes of the limiting protrusions 311 may be the same or different.

[0079] When it is necessary to upgrade and update the data of chip 500, first embed part of the main body 110 of the code writing and reading device 100 into the fixing groove 210 of the positioning bracket 200, and let the spring pin 120 of the code writing and reading device 100 pass through the positioning through hole 221. At this time, the snap-fit ​​part 211 on the groove wall of the fixing groove 210 snaps into the snap-fit ​​groove 112 on the main body 110, thereby realizing the connection between the code writing and reading device 100 and the positioning bracket 200. Then, the positioning bracket 200 is aligned with the chip holder 400, and the positioning bracket 200 is moved downward so that the positioning rib 430 on the chip holder 400 is embedded in the second positioning groove 213 on the positioning bracket 200, and the first elastic arm 230 and the second elastic arm 240 of the positioning bracket 200 are respectively inserted into the first gap 440 and the second gap 450 of the chip holder 400. At the same time, the first chip limiting plate 421 and the second chip limiting plate 422 on the chip holder 400 are limited in the clamping space between the first elastic arm 230 and the second elastic arm 240, and the second limiting part 250 on the first elastic arm 230 and the second elastic arm 240 contacts and fastens with the first limiting part 423 on the first chip limiting plate 421 and the second chip limiting plate 422 in the direction from the spring pin 120 to the device body 110, thereby realizing the connection between the positioning bracket 200 and the chip holder 400. At this time, the spring pin 120 is in a compressed state and contacts the contact point 510 on the chip 500.

[0080] It should be noted that the clamping force between the second limiting part 250 and the first limiting part 423 is greater than the elastic force of the spring pin 120. This ensures the connection stability between the positioning bracket 200 and the chip fixing seat 400, and ensures that the spring pin 120 can be in a compressed state, thereby improving the electrical conductivity between the spring pin 120 and the chip 500.

[0081] After the data transmission between the code writing / reading device 100 and the chip 500 is completed, that is, after the data upgrade and update of the chip 500 is completed, a force is applied to the code writing / reading device assembly away from the chip fixing base 400, that is, the code writing / reading device 100 is pulled upward, causing the first elastic arm 230 and the second elastic arm 240 of the positioning bracket 200 to deform, thereby allowing the second limiting part 250 to separate from the first limiting part 423, thus allowing the positioning bracket 200 to separate from the chip fixing base 400. Finally, the code writing / reading device 100 is removed, and the entire data transmission is completed.

[0082] Optionally, the main body of the printing consumable 300 can be a toner cartridge.

The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
