Description

Technical Field

[0001] The present disclosure relates to the technical field of printer consumables, and in particular to a chip writing and reading device. Background Art

[0002] Printing consumables have a chip that records information about the printing consumables. When the printing consumables are installed in the printer body, the printer's processor can communicate with the chip. The data in the chip of the manufactured printing consumables is sometimes modified according to customer requirements, so the chip of the manufactured printing consumables needs to be read and written. Common chip reading and writing devices include handheld test heads, which are connected to the chip to achieve electrical connection. During this operation, it is necessary to manually maintain the electrical connection for a certain period of time to achieve data transmission between the chip reading and writing device and the chip until the data transmission is completed.

[0003] However, during manual operation, manually maintaining downward pressure will cause hand fatigue and be time-consuming and labor-intensive. Utility Model Content

For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present disclosure can be understood according to specific circumstances.

[0048] refer to Figure 1 , Figure 1 The chip code writing and reading device 1000 provided by the embodiment of the present disclosure includes a positioning member 100, a test head body 200 and a hook 300. Figure 2 and Figure 13 As shown, the chip code writing and reading device 1000 includes a test head 1001, and the positioning member 100, the test head body 200 and the hook 300 are used to constitute the test head 1001. The test head 1001 may include at least two hooks 300.

[0049] The chip writing and reading device 1000 is used to write and read codes on a chip 2003. For example, the chip 2003 is a component of the printing consumable 2000 and can store information data related to the printing consumable 2000. The printing consumable 2000 may include a housing 2001, a chip holder 2002, and a chip 2003. The chip holder 2002 is connected to the housing 2001. The chip 2003 is disposed on the chip holder 2002 of the printing consumable 2000 along a first direction, which may be parallel to the Z-axis. The chip holder 2002 has an outwardly convex flange 2022 surrounding the chip 2003. The outwardly convex flange 2022 protrudes from the chip holder body 2012 of the chip holder 2002 along the XY plane.

[0050] It should be noted that common printing consumables 2000 include toner cartridges, ink cartridges, etc. For ease of understanding, the embodiments of this disclosure mainly take toner cartridges as an example, but it is easy to understand that as long as printing consumables with a chip seat 2002 and a chip 2003 are required, the inventive concept of this specification is applicable, including but not limited to toner cartridges.

[0051] by Figure 1 The Z-axis is vertical, and the chip writing and reading device 1000 and the printing consumable 2000 can be docked in the vertical direction. It is easy to understand that the docking direction of the chip writing and reading device 1000 and the printing consumable 2000 is not limited to vertical docking. In addition, different postures can be maintained or adjusted after docking.

[0052] Combine Figures 3 to 7 As shown, in some embodiments, the test head body 200 includes a probe 5 for electrically connecting to the chip 2003. Optionally, the needle tip of the probe 5 can be elastic to absorb the deviation of the docking size and maintain the electrical connection state.

[0053] like Figure 4 、 Figure 5 and Figure 7As shown, positioning member 100 is connected to test head body 200. Positioning member 100 includes a docking portion 1, through which probe 5 passes. Docking portion 1 is used to dock with chip holder 2002 along a first direction. Depending on the depth of chip 2003 relative to chip holder 2002, docking portion 1 can be attached to chip 2003.

[0054] The chip writing / reading device 1000 includes at least two hooks 300 for engaging with the chip holder 2002. These hooks 300 are arranged around the docking portion 1. For example, the chip writing / reading device 1000 includes at least two hooks 300 arranged opposite each other along the Y-axis, which can be parallel to the second direction. At least during engagement, the hooks 300 are positioned relative to the test head body 200, and the hooks 300 cooperate with the docking portion 1 to ensure a stable connection between the chip writing / reading device 1000 and the printing consumable 2000.

[0055] These hooks 300 are used to surround the chip holder 2002, optionally intermittently. Space is formed between these hooks 300, and the space between at least two hooks 300 can be expanded or repositioned. The engaging portion 4 of at least one hook 300 is resilient relative to the test head body 200, allowing the engaging portion 4 to engage with or disengage from the convex flange 2022.

[0056] Specifically, when connecting the chip code writing and reading device 1000 to the printing consumable 2000, the latching portion 4 can be forced to spring, ensuring that the docking portion 1 is docked with the chip holder 2002 and the probe 5 is electrically connected to the chip 2003. The latching portion 4 can then snap into place with the convex flange 2022 of the chip holder 2002 in its natural or near-natural state. This allows the operator to write and read codes on the chip 2003 without manual support. After code writing and reading are completed, the latching portion 4 can be made to spring, allowing the chip code writing and reading device 1000 to be detached from the printing consumable 2000.

[0057] By providing the positioning member 100 and the hook 300 , it is ensured that the probe 5 can be stably electrically connected to the chip 2003 for a period of time, and the connection and removal of the chip writing and reading device 1000 and the printing consumables 2000 are achieved through the elasticity of at least one clamping part 4 .

[0058] The chip code writing and reading device 1000 of the embodiment of the present disclosure is easy to operate.

[0059] In some embodiments, the hook 300 clamps the chip holder 2002 , which helps to accurately align the probe 5 with the chip 2003 .

[0060] refer to Figure 1 、 Figure 6 、 Figure 7 and Figure 8In some embodiments, the positioning member 100 further includes a positioning portion 9, which surrounds the docking portion 1 and is configured to fit snugly over the chip holder 2002. For example, if the chip holder 2002 is rectangular, the inner circle of the positioning portion 9 can be rectangular or configured to grip the four edges of the chip holder 2002 to prevent rotation in the XY plane. This positioning portion 9 allows for accurate positioning, ensuring a good electrical connection between the probe 5 and the chip 2003.

[0061] For example, the positioning portion 9 has a groove for avoiding the hook 300. The positioning portion 9 can be divided into several segments, each of which is respectively against the chip holder 2002. Along the Z-axis direction, the positioning portion 9 protrudes from the docking portion 1, and the position of the clamping portion 4 can protrude from the positioning portion 9.

[0062] refer to Figure 4 and Figure 5 In some embodiments, the chip code writing and reading device 1000 further includes at least one elastic member 7. Each hook 300 may correspond to one elastic member 7, or may correspond to multiple elastic members 7. The elastic member 7 may be a tension spring, a torsion spring, an elastomer, or the like, to provide a force in a predetermined direction to the hook 300. Exemplarily, the elastic member 7 is a compression spring, and the elastic member 7 is compressed by the positioning member 100 and the hook 300, or by the test head body 200 and the hook 300.

[0063] The positioning member 100 further includes a mounting portion 2 connected to the test head body 200. Figure 7 and Figure 8 The test head body 200 may be provided with a mounting groove, and the mounting portion 2 may be embedded in the mounting groove. By configuring the mounting portion 2, the structure of the chip writing and reading device 1000 is easier to manufacture.

[0064] Each hook 300 includes a connecting portion 3 and a clamping portion 4. The connecting portion 3 is positioned relative to the test head body 200, and the clamping portion 4 protrudes from the docking portion 1 along a first direction. For example, the connecting portion 3 of at least one hook 300 is rotatably connected to the mounting portion 2. The elastic member 7 is used to drive the corresponding connecting portion 3 to bring the corresponding clamping portion 4 closer to the other clamping portion 4. The elastic member 7 drives the rotational arrangement of the hook 300, ensuring a stable connection between the docking portion 1 and the probe 5 when connected to the printing consumable 2000, allowing for flexible operation of the hook 300 and ensuring its service life.

[0065] refer to Figure 4 、 Figure 8 and Figure 9In some embodiments, the hook 300 further includes a button 8. The button 8 is connected to the connecting portion 3. The button 8 and the engaging portion 4 are located on opposite sides of the connecting portion 3, forming a lever. The placement of the button 8 allows for effective force application. Optionally, the button 8 and the engaging portion 4 are located on opposite sides of the connecting portion 3. The button 8 can be used to control the engaging portion 4, enabling the two hooks 300 to engage and disengage, thereby facilitating the connection and disconnection of the chip writing and reading device 1000 and the printing consumables 2000.

[0066] In some embodiments, the elastic member 7 is a compression spring. For example, the elastic member 7 is compressed by the mounting portion 2 and the button 8 to maintain a preload. Inserting the elastic member 7 through the button facilitates a compact structure, provides ample room for elastic deformation, and facilitates installation of the elastic member 7.

[0067] refer to Figure 1 、 Figure 3 and Figure 4 In some embodiments, the test head body 200 includes a housing, which includes an outer bottom 210 and an outer cover 220 that are coupled together along the second direction. The structures of the outer bottom 210 and the outer cover 220 can be similar. For example, the test head body 200 includes a circuit assembly 230, which is disposed on the outer bottom 210, for example, by screws. The outer cover 220 can be fastened to the outer bottom 210, for example, by screws.

[0068] The positioning member 100 and the hook 300 are removably mounted to the housing. For example, the mounting portion 2 and the connecting portion 3 are located within the housing, effectively protecting the various components. The button 8 passes through the outer bottom 210 or the outer cover 220, ensuring access to the hook 300. The test head 1001 and the chip writing and reading device 1000 that includes it are both easy to assemble and manufacture, while also protecting the circuit assembly 230 and the hook 300.

[0069] refer to Figure 1 、 Figure 4 and Figure 8 In some embodiments, the mounting portion 2 has a rotational engagement groove 12. The connecting portion 3 serves as a connecting shaft. The test head body 200 and the mounting portion 2 clamp the connecting portion 3 with a gap, restricting the connecting portion 3 within the rotational engagement groove 12. This gap ensures sufficient rotational space for the connecting portion 3 and, consequently, the hook 300. By cleverly utilizing the structure of the assembled test head body 200 and the positioning member 100, the required motion restriction of the hook 300 is achieved. The components are simple in structure and easy to install.

[0070] refer to Figure 1 and Figure 4The hook 300 has a first support surface 10 and a second support surface 11. The cross-section of the first support surface 10 in the YZ plane is tilted relative to the Z axis, forming a gap with the positioning member 100 that gradually increases in the direction away from the connecting portion 3, ensuring that the button 8 can be pressed. The cross-section of the second support surface 11 in the YZ plane is tilted relative to the Z axis. The tilted design of the first and second support surfaces 10 and 11 not only ensures the movement space of the button 8, but also provides a certain degree of support for the hook 300, preventing serious deformation of the hook 300, making the hook 300 more structurally strong, long-lasting, and durable.

[0071] refer to Figure 10 , Figure 10 FIG. 1 shows a chip code writing and reading device according to an embodiment of the present disclosure. In some embodiments, the chip code writing and reading device 1000 includes a positioning member 100 , a test head body 200 , and at least two hooks 300 . The hooks 300 can be fixedly connected to the test head body 200 .

[0072] Exemplarily, the test head body 200 includes a housing. The docking portion 1 is spaced apart from the housing along a second direction perpendicular to the first direction. The hook 300 may be located within this space. The housing may include a clearance gap to accommodate the hook 300. The hook 300 is integrally formed with the outsole 210 or the outer cover 220.

[0073] The optional hook 300 includes a connecting portion 3 and a snap-on portion 4. The connecting portion 3 is located between the housing and the docking portion 1. The connecting portion 3 is an elastic connection fixed to the housing, allowing the snap-on portion 4 to spring in a second direction relative to the test head body 200. The hook 300 achieves this springing of the snap-on portion 4 by deforming its own elastic connecting portion 3, without the need for external components. This allows the test head 1001 of the chip writing and reading device 1000 to have fewer parts, resulting in a simple overall structure and quick assembly.

[0074] In some embodiments, the connecting portion 3 is configured as a curved structure that bulges inward from the housing. When forced to move, the engaging portion 4 moves outward. Consequently, the elastic deformation of the curved connecting portion 3 reduces its diameter and increases its wrap angle. While tension is applied to the outer diameter of the connecting portion 3, its longer, smoother outer periphery disperses the applied force. This curved structure helps ensure the performance and service life of the connecting portion 3.

[0075] refer to Figure 11 , Figure 11The chip writing and reading device of the embodiment of the present disclosure is shown. In the chip writing and reading device 1000, the extension direction of the hook 300 is inclined relative to the Z-axis direction, and the hook 300 gradually tilts outward from the connecting portion 3 to the clamping portion 4. When multiple hooks 300 are clamped with the chip holder 2002, the resultant force on the multiple hooks 300 is roughly along the Z-axis direction, and for each hook 300, the force it receives can be decomposed into a component force along the extension direction and a component force perpendicular to the extension direction. This vertical component force can promote the deformation of the hook 300 and prevent the hook 300 from being damaged by simple tension when it is stuck. Such an inclined setting is conducive to ensuring the service life of the hook 300.

[0076] refer to Figure 12 , Figure 12 A chip code writing and reading device according to an embodiment of the present disclosure is shown. The chip code writing and reading device 1000 includes a positioning member 100, a test head body 200, and at least two hooks 300. The hook 300 can be fixedly connected to the test head body 200. The test head body 200 includes a housing. The docking portion 1 is spaced apart from the housing along a second direction perpendicular to the first direction. The hook 300 can be located in the space. Any hook 300 includes a connecting portion 3 and a clamping portion 4, and the connecting portion 3 is located between the housing and the docking portion 1.

[0077] Exemplarily, the connecting portion 3 is a rigid connecting portion, and the clamping portion 4 is capable of resiliently moving in a second direction relative to the connecting portion 3. The resilient direction of the clamping portion 4 may intersect with the first direction, but in the second direction, the clamping portion 4 is ensured to cross the edge of the convex flange 2022 of the chip holder 2002. In the engaged state, the clamping portion 4 is interference-fitted between the main body of the hook 300 and the chip holder 2002. By providing a rigid connecting portion and configuring the clamping portion 4 to resiliently move, the clamping portion 4 and the convex flange 2022 of the chip holder 2002 are engaged through elastic deformation of the clamping portion 4. During this process, the connecting portion 3 is substantially free of deformation, which helps to ensure the service life of the connecting portion 3. Furthermore, the overall structure of the clamping portion 300 is simpler, eliminating the need for additional structures that cooperate with the mounting portion 2.

[0078] refer to Figure 13 In some embodiments, the chip writing and reading device 1000 further includes a data input device 1003 and a data line 1002. The data input device 1003 is electrically connected to the circuit assembly 230 of the test head body 200 via the data line 1002, facilitating the docking unit 1 to be docked with the printing consumable 2000, and enabling the data input device 1003 to operate normally.

[0079] For example, data line 1002 is detachably connected to a second interface of test head 1001 via a first interface. The second interface of test head 1001 may be disposed on circuit board structure 6 of circuit assembly 230 and electrically connected to probe 5 via circuit board structure 6. The second interface and probe 5 may face each other in opposite directions along the Z-axis.

[0080] For example, the data line 1002 has a certain degree of flexibility and can be bent. The data input device 1003 may include a memory and a processor. The data input device 1003 may include a touch screen.

[0081] The technical features of the embodiments disclosed above can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0082] The embodiments disclosed above merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent protection of the present application. It should be noted that a person skilled in the art could make several variations and improvements without departing from the concept of the present application, all of which fall within the scope of the patent protection claimed by the present application. Therefore, the scope of the patent protection of the present application shall be subject to the appended claims.
