For example, "connection" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0066] In the description of this specification, it should be understood that the orientation terms such as "upper" and "lower" described in the embodiments of the present application are described from the angles shown in the drawings and should not be construed as limiting the embodiments of the present application. In addition, in the context, it should also be understood that when it is mentioned that one component is connected "above" or "below" another component, it can not only be directly connected "above" or "below" another component, but also be indirectly connected "above" or "below" another component through an intermediate component.

[0067] The consumable cartridge is an important component in a printing device. When the printing device is an inkjet printer, the corresponding consumable cartridge is an ink cartridge storing ink; when the printing device is a laser printer, the corresponding consumable cartridges are a processing cartridge, a developing cartridge, a toner cartridge, etc. storing toner.

[0068] In order to store information such as the production factory information of the consumable cartridge, the ink volume information, the consumable cartridge category information, and the ink color, generally, a chip is provided on the consumable cartridge. The chip is generally fixed to the consumable cartridge by means of gluing or welding. The installation position of the chip is lower than the plane of the consumable cartridge where the chip is located. Existing chip disassembly tools and disassembly methods are difficult to disassemble it, or it is easy to damage the chip during the disassembly process, resulting in inability to recycle.

[0069] The present application discloses a chip disassembly fixture. The chip disassembly fixture disassembles the bearing part along the edge of the bearing part through the disassembly part, so that the bearing part and the chip installed on the bearing part are separated from the ink cartridge together, which facilitates the recycling and reuse of the chip and avoids the waste of chip resources.

[0070] To make the solution easy to understand, first, a brief introduction to the ink cartridge 1 of the prior art is given. The ink cartridge 1 is generally used for installation in a recording device (such as a printer), and the ink cartridge 1 stores ink. When the recording device records, the ink in the ink cartridge 1 will be displayed on the recording medium (such as paper, or other printing media that can carry ink).

[0071] Reference Figures 1 to 3As shown, the ink cartridge 1 includes a housing 11, a handle portion 12, a first engaging portion 121, and a second engaging portion 111. The housing 11 is used to contain ink, and an ink outlet 14 is provided at the bottom (-Z direction) of the housing 11. The ink outlet 14 is used to discharge the ink in the housing 11 onto a recording device. The handle portion 12 is provided on the +X side of the housing 11, and the handle portion 12 is inclined with respect to the +X side of the housing 11. The first engaging portion 121 is provided on the handle portion 12, and the first engaging portion 121 extends in the X direction away from the handle portion 12. The second engaging portion 111 protrudes on the -X side of the housing 11, and the second engaging portion 111 is disposed opposite to the handle portion 12 and is closer to the ink outlet 14 than the handle portion 12. When the ink cartridge is installed on the recording device, the handle portion 12 is engaged with the recording device; the second engaging portion 111 is also engaged with the recording device. Thus, under the action of the first engaging portion 121 and the second engaging portion 111, the ink cartridge 1 is stably fixed on the recording device to achieve ink filling.

[0072] The ink cartridge 1 further includes a chip 13. The chip 13 is provided at the bottom of the housing 11, and cartridge information is stored in the chip 13. The chip 13 is disposed in the same plane as the ink outlet 14 and is closer to the handle portion 12 than the ink outlet 14. Generally, the chip 13 can be installed on the housing 11 by welding. The chip 13 can be used to record information such as the ink volume of the ink cartridge 1 and the number of times the ink cartridge 1 is used. When the ink cartridge 1 is installed on the recording device, the chip 13 can transmit the information on the chip 13 to the recording device by being electrically connected to the recording device. To avoid resource waste, the chip 13 on the ink cartridge 1 can be removed and installed on a new ink cartridge for reuse. The ink cartridge chip disassembly fixture 2 of the present application is for disassembling the chip 13.

[0073] It should be noted that in the following description, the length direction of the ink cartridge is defined as the X direction, the width direction of the ink cartridge is defined as the Y direction, and the height direction of the ink cartridge is defined as the Z direction. The X direction, Y direction, and Z direction are perpendicular to each other.

[0074] Embodiment 1

[0075] As Figure 4 Figure 5As shown, this embodiment discloses a chip disassembly fixture 2, which includes a fixture component 20, a disassembly portion 30, and a force application portion 40. The fixture component 20 includes a positioning portion 21, which is used to position the ink cartridge to prevent the ink cartridge from moving during the chip disassembly process. The positioning portion 21 is provided with an opening portion 211, and the position of the opening portion 211 corresponds to the position of the chip 13 on the ink cartridge, for exposing and positioning the chip 13. The disassembly portion 30 is movably installed on the fixture component 20, and the disassembly portion 30 can move relative to the fixture component 20 to disassemble the chip assembly, where the chip assembly includes a chip carrier portion and a chip provided on the chip carrier portion. Exemplarily, when the disassembly portion 30 moves on the fixture component 20, the disassembly portion 30 can disassemble the chip carrier portion where the chip 13 is located, so that the chip 13 on the chip carrier portion is also removed together. The force application portion 40 is installed on the fixture component 20, and the force application portion 40 can move relative to the fixture component 20. The force application portion 40 is used to receive an external force to drive the disassembly portion 30 to move, so that the disassembly portion 30 moves on the fixture component 20 to disassemble the chip 13 and the chip carrier portion. The chip disassembly fixture 2 of this embodiment drives the disassembly portion 30 to move on the fixture component 20 through the force application portion 40, and can thus disassemble the chip 13 and the chip carrier portion on the ink cartridge. Its structure is simple and the operation is convenient, solving the problem of difficult operation during the installation or disassembly of the chip 13 on the ink cartridge 1 in the prior art, and greatly improving the reusability of the chip 13.

[0076] Further, the opening portion 211 penetrates through the positioning portion 21 of the fixture component 20 in the height direction, and the length of the opening portion 211 is greater than the length of the chip 13, so that the chip can be completely exposed from the opening portion 211 during the chip disassembly process, facilitating the taking of the disassembled chip 13 and the chip carrier portion.

[0077] Referring to Figure 6 As shown, the fixture component 20 further includes a first engaged portion 212 and a second engaged portion 213, and the first engaged portion 212 and the second engaged portion 213 are located on both sides of the positioning portion 21 in the X direction. Among them, the first engaged portion 212 is used to engage with the first engaged portion 121 on the ink cartridge housing, and the second engaged portion 213 is used to engage with the second engaged portion 111 on the ink cartridge housing, so that the positioning portion 21 can be stably engaged with the housing of the ink cartridge, ensuring the positioning of the disassembly portion 30 and the carrier portion where the ink cartridge chip 13 is located.

[0078] Also referring to Figure 6 and Figure 7As shown, the fixture member 20 further includes an assembling portion 20a which is connected to the positioning portion 21 and located between the positioning portion 21 and the force - applying portion 40. The dismounting portion 30 is inclinedly installed on the assembling portion 20a, so that an inclined dismounting path is formed during the movement of the dismounting portion 30, and the inclined dismounting path extends along the axial direction of the force - applying portion 40. Specifically, the positioning portion 21 is provided with a positioning groove 21a, and the assembling portion 20a is provided with an installation groove 22 and an installation hole 224. The installation groove 22 is located between the positioning groove 21a and the force - applying portion 40. Among them, when the fixture member 20 is installed on the ink cartridge, during normal disassembly, the installation groove 22 is a groove with an open bottom; when the fixture member 20 is placed in reverse, the installation groove 22 is a groove with an upward - opening. The installation hole 224 is located between the installation groove 22 and the positioning groove 21a, and the installation groove 22, the installation hole 224 and the positioning groove 21a are respectively communicated. The dismounting portion 30 is arranged in the installation groove 22 and can slide in the installation groove 22, so that a part of the structure of the dismounting portion 30 can extend into the positioning groove 21a through the installation hole 224 to realize the disassembly of the chip.

[0079] To limit the dismounting portion 30, the fixture member 20 further includes a first limiting portion and a second limiting portion. The first limiting portion is arranged on both sides in the installation groove 22 and is used to limit the dismounting portion 30 in the depth direction of the installation groove 22. The second limiting portion is arranged at the end of the installation groove 22 and is used to limit the dismounting portion 30 in the length direction of the installation groove 22.

[0080] Refer to Figures 8 to 10 As shown, the installation groove 22 is provided with a bottom surface 22a and two relatively - arranged side surfaces. Each side surface respectively includes a first part 22b and a second part 22c. The width between the two first parts 22b is different from the width between the two second parts 22c, and the width between the two second parts 22c is greater than the width between the two first parts 22b. And a limiting end surface 222 is arranged at the end of the first part 22b close to the bottom surface. A gap 221 is formed between the limiting end surface 222 and the bottom surface 22a to form the first limiting portion.

[0081] Refer to Figure 11 As shown, the dismounting portion 30 is set as a cutting knife. The cutting knife includes a knife head 33, a knife body 32 and a pushed portion 31. Preferably, the knife head 33, the knife body 32 and the pushed portion 31 can be an integrally - formed structure. The knife head 33 and the pushed portion 31 are respectively located at both ends of the knife body 32. The knife head 33 has a wedge - shaped structure, and the knife head 33 is arranged at the horizontally - arranged end of the knife body 32, and the pushed portion 31 is arranged on the vertically - arranged part of the knife body 32, so that the dismounting portion 30 is generally in an "L" - shaped structure as a whole.

[0082] When the disassembly part 30 moves on the fixture part 20, one end of the cutter head 33 of the disassembly part 30 is set close to the positioning part 21, and one end of the pushed part 31 of the disassembly part 30 is set close to the force-applying part 40. The pushed part 31 abuts against the force-applying part 40 and can receive the drive of the force-applying part 40 to move the disassembly part 30 in the installation groove 22, so that the cutter head 33 can move along a preset track to disassemble the chip 13 and the chip 13 carrying part from the cartridge housing.

[0083] Referring to Figure 12 As shown, the cutter body 32 includes a first cutter body part 32a and a second cutter body part 32b that are connected to each other. The pushed part 31 is connected to one end of the second cutter body part 32b away from the first cutter body part 32a, and the cutter head 33 is connected to one end of the first cutter body part 32a away from the second cutter body part 32b. Moreover, the widths of the first cutter body part 32a and the second cutter body part 32b are different, and the width of the second cutter body part 32b is greater than the width of the first cutter body part 32a. The width of the first cutter body part 32a corresponds to the width between the two first parts 22b in the installation groove 22, and the width of the second cutter body part 32b corresponds to the width between the two second parts 22c in the installation groove 22. When the disassembly part 30 is installed in the installation groove 22, the part of the second cutter body part 32b protruding from the first cutter body part 32a can move in the gap 221 and is prevented from falling out of the installation groove 22 under the limitation of the limiting end face 222. At the same time, a first limited part 23b1 is also provided at the front end of the part of the second cutter body part 32b protruding from the first cutter body part 32a.

[0084] When the disassembly part 30 is installed in the installation groove 22, the cutter head 33 of the disassembly part 30 can extend into the positioning groove 22 through the installation hole 224. The cutter body 32 and the pushed part 31 of the disassembly part 30 can be pushed by the force-applying part 40 to move in the installation groove 22, so that the cutter head 33 moves in the installation hole 224 to disassemble the chip 13 positioned by the positioning part 21 and the chip carrying part.

[0085] In this embodiment, the assembly part 20a is provided with an inclined installation surface, and the disassembly part 30 is installed on this inclined installation surface. Specifically, the bottom surface 22a can be set to be inclined, and in the length direction of the positioning part 21, the height of one side of the bottom surface 22a is higher than the height of the other side of the bottom surface 22a, that is, the height of the first side end face 22a1 is higher than the height of the second side end face 22a2, forming an inclined installation surface, and the disassembly part 30 is installed on the inclined bottom surface 22a.

[0086] In some other embodiments, the disassembly part 30 can also be set to be inclined, or the cutter head 33 on the disassembly part 30 can be set to be inclined. In this way, the bottom surface 22a of the installation groove can be set to be inclined or non-inclined, as long as the final inclined shape is the same as the inclined shape of the bottom surface 22a in the above installation groove 22, that is, the disassembly can be carried out according to the above inclined preset path, and no limitation is made here.

[0087] Continue to refer to Figure 8 As shown, the second limiting part 223 is the end face where both sides of the installation groove 22 are connected to the bottom surface, and it is flush with the end face of the installation hole 224. When the disassembly part 30 moves along the +Y axis direction in the installation groove 22 to the position of the second limiting part 223, the first limited part 23b1 on the tool body 32 is blocked and limited by the second limiting part 223, and the disassembly part 30 can no longer move, so that the moving distance of the disassembly part 30 in the installation groove 22 is fixed, and the position where the cutter head 33 on the disassembly part 30 inserts into the shell of the ink cartridge is fixed. At the same time, the disassembly part 30 cuts the carrier part where the chip is located from one end to the other end, and cuts off the chip and the carrier part where the chip is located from the shell of the ink cartridge.

[0088] At the same time, refer to Figure 10 and Figure 13 As shown, the force application part 40 includes a driving part 42 and a handle 41. The driving part 42 is installed on the fixture part 20 and can move, so as to abut against the pushed part 31 of the disassembly part 30 in the installation groove 22. The handle 41 is connected to the driving part 42, and the handle 41 can receive an external force to drive the driving part 42 to move on the fixture part 20, so as to push the disassembly part 30 to move and disassemble the chip 13. Specifically, the fixture part 20 is provided with a screw hole 23. In the width Y direction of the fixture part 20, the screw hole 23 is arranged at the other end of the fixture part 20 opposite to the positioning part 21. On the fixture part 20, the installation hole 224, the installation groove 22 and the screw hole 23 are arranged in sequence in the width direction of the fixture part 20, and both the installation hole 224 and the screw hole 23 communicate with the installation groove 22. The driving part 42 is a cylindrical structural part, and the outer circumferential surface of the driving part 42 is provided with a thread 421. The driving part 42 is installed in the screw hole 23 by matching the thread 421 with the internal thread 231 in the screw hole 23, and the driving part 42 can move and rotate in the screw hole 23 through the cooperation of the thread 421 and the internal thread 231 in the screw hole 23. One end of the driving part 42 connected with the handle 41 extends outside the fixture part 20, and the other end of the driving part 42 passes through the screw hole 23 and falls into the installation groove 22 to abut against the pushed part 31 on the disassembly part 30. When in use, the handle 41 can be rotated outside the fixture part 20, so that the driving part 42 can rotate in the screw hole 23, and one end of the driving part 42 in the installation groove 22 pushes the disassembly part 30 to move on the installation groove 22, and the disassembly part 30 can disassemble the chip 13 and the chip carrier part. In some other embodiments, the driving part 42 can also be a prismatic structural part, which is not limited here.

[0089] Refer to Figures 14 to 16 As shown, when the chip disassembly fixture in this embodiment is in use:

[0090] First, the fixture member 20 is engaged with the engaging portion on the ink cartridge housing through the engaged portion of the positioning portion 21, so that the position of the chip 13 corresponds to the opening portion 211 on the fixture member 20, thereby exposing the chip 13 through the opening portion 211 of the positioning portion 21.

[0091] Then, rotate the handle 41 of the biasing portion 40, the rotary driving member 42 moves on the fixture member 20, pushing the disassembly portion 30 to move within the mounting groove 22 and the mounting hole 224, so that the cutting head 33 of the disassembly portion 30 extends into the ink cartridge housing along the inclined bottom surface and the inclined direction of the chip 13, that is, the bearing portion where the chip is located. Continue to rotate the biasing portion 40, pushing the disassembly portion 30 to move until the first limited portion 32b1 abuts against the second limiting portion 223, and the disassembly portion 30 cuts off the bearing portion where the chip is located, and the chip and the chip bearing portion are disassembled from the ink cartridge housing.

[0092] Finally, install the disassembled chip 13 and the chip bearing portion on the chip mounting portion of the new ink cartridge.

[0093] Embodiment 2

[0094] This embodiment provides another chip disassembly fixture. The difference between this embodiment and Embodiment 1 is that the structures of the disassembly portion and the mounting groove in this embodiment are different from those of the disassembly portion and the mounting groove in Embodiment 1.

[0095] As Figure 17 and Figure 21 shown, in this embodiment, the chip disassembly fixture further includes two third limiting portions 221, which are respectively arranged at the bottom of the mounting groove 22 and on both sides within the mounting groove 22, and the distance between the two third limiting portions 221 is less than the distance between the two sides of the mounting groove 22. The third limiting portion 221 is used to limit the disassembly portion 30 in the width direction of the mounting groove 22. A protrusion is further provided on the end surface of the mounting groove 22 close to the positioning portion 21. The protrusion protrudes along the direction away from the positioning portion 21, and is arranged at the upper part of the mounting groove 22 and is connected to the side surface of the mounting groove 22. It can also be integrally formed. And a engaging portion 222 is provided on the protrusion facing the bottom of the mounting groove 22. One end of the engaging portion 222 is connected to the protrusion, and the other end is suspended. There is a gap between the engaging portion 222 and the bottom and side surface of the mounting groove 22 in the height and length directions, forming a first limiting portion. Among them, the number of the engaging portions 222 is also set to two, and the two engaging portions 222 are arranged oppositely. And the end of the engaging portion 222 close to the bottom of the mounting groove 22 protrudes more than the protrusion, that is, the distance between the two engaging portions 222 is less than the distance between the two protrusions, and the distance between the two protrusions is basically the same as the distance between the two third limiting portions 221.

[0096] In this embodiment, the bottom surface of the installation groove 22 is also inclined, and its inclined state can be the same as that of the bottom surface of the installation groove described in the first embodiment, that is, in the length direction of the positioning portion 21, the height of one side of the bottom surface of the installation groove 22 is higher than that of the other side, forming an inclined installation surface. The disassembly portion 30 is installed on the inclined bottom surface of the installation groove 22, so that the disassembly portion 30 forms an inclined disassembly path when moving.

[0097] As Figure 22 and Figure 23 shown, the disassembly portion 30 includes a cutter head 33, a cutter body 32, and a pushed portion 31. The cutter body 32 includes a first cutter body portion 322 and two second cutter body portions 321. The two second cutter body portions 321 are respectively connected to both sides of the first cutter body portion 322 to form a "U" - shaped structure. The pushed portion 31 is connected to the first cutter body portion 322, and the setting direction of the pushed portion 31 is exactly opposite to the setting direction of the two second cutter body portions 321. The cutter head 33 is provided with three, and the three cutter heads 33 are respectively connected to the first cutter body portion 322 and the two second cutter body portions 321. In some other embodiments, the cutter head here can also be set to two, four or more, which is not limited here.

[0098] When the disassembly portion 30 is installed in the installation groove 22, the inner sides of the two second cutter body portions 321 are in contact with the third limiting portion 221, so that the third limiting portion 221 can limit the disassembly portion 30 from moving along the length direction in the installation groove 22. At the same time, the first cutter body portion 322 is in contact with the engaging portion 222 to prevent the disassembly portion from falling out of the installation groove 22.

[0099] Referring to Figure 24 shown, the second limiting portion 223 protrudes on the end of the installation groove 22 far from the positioning portion 21. When the disassembly portion 30 moves along the + Y - axis direction in the installation groove 22, the pushed portion 31 on the disassembly portion 30 is limited by the second limiting portion 223, so that the moving distance of the disassembly portion 30 in the installation groove 22 is fixed, and the position where the cutter head 33 on the disassembly portion 30 inserts into the shell of the ink cartridge is fixed. Specifically, the second limiting portion 223 is the end surface of the protrusions on both sides of the installation groove 22 far from the positioning portion, and it is parallel to the end surface of the installation hole 224. When the disassembly portion 30 moves to the position of the second limiting portion 223 in the installation groove 22, the pushed portion 31 on the disassembly portion 30 is blocked by the second limiting portion 223, and the disassembly portion 30 can no longer move. The disassembly portion 30 disassembles the carrier portion where the chip is located from three sides, and cuts off the chip and the carrier portion where the chip is located from the shell of the ink cartridge.

[0100] Referring to Figure 25 and Figure 26 shown, when the chip disassembly fixture in this embodiment is in use:

[0101] First, the fixture member 20 is engaged with the engaging portion on the ink cartridge housing through the engaged portion of the positioning portion 21, so that the position of the chip 13 corresponds to the opening portion 211 on the fixture member 20, thereby exposing the chip 13 through the opening portion 211 of the positioning portion 21.

[0102] Then, rotate the handle 41 of the biasing portion 40, the rotary driving member 42 moves on the fixture member 20, pushing the disassembly portion 30 to move within the mounting groove 22 and the mounting hole 224, so that the cutter head 33 of the disassembly portion 30 extends into the ink cartridge housing, that is, the carrying portion where the chip is located. Continue to rotate the biasing portion 40, pushing the disassembly portion 30 to move until the pushed portion 31 abuts against the second limiting portion 223, and the disassembly portion 30 cuts off the carrying portion where the chip is located from three sides, and the chip and the chip carrying portion are disassembled from the ink cartridge housing.

[0103] Finally, install the disassembled chip 13 and the chip carrying portion on the chip installation portion of the new ink cartridge.

[0104] In this embodiment, other structures and descriptions are the same as those in Embodiment 1, and will not be described here.

[0105] In some other embodiments, the bottom surface of the mounting groove 22 can also be set as a plane, and the chip and the chip carrying portion are disassembled from the ink cartridge housing by using the three-sided cutter head of the disassembly portion.

[0106] In some other embodiments, the mounting groove 22 of the fixture member in the above two embodiments can also be set reversely and connected to the positioning portion 21 in the above two embodiments. For example, during normal disassembly, the mounting groove 22 can be set as a groove with an opening at the top, so that the movement process of the disassembly portion 30 can be seen during the disassembly process, and it can further prevent the disassembly portion from falling off, making the disassembly process more convenient.

[0107] The ink cartridge chip disassembly fixture provided by the present application positions the ink cartridge and the chip through the positioning portion, and applies a force to the disassembly portion through the biasing portion, so that the disassembly portion acts on the chip carrying portion, separating the chip carrying portion from the ink cartridge housing, and thus the chip and the chip carrying portion on the ink cartridge can be disassembled. The structure is simple and the operation is convenient, solving the problem of difficult operation during the disassembly of the chip on the ink cartridge in the prior art, shortening the disassembly time, improving the disassembly efficiency, saving time and effort, and the chip disassembly fixture has a relatively simple structure, relatively low manufacturing difficulty and manufacturing cost, greatly improving the reusability of the chip.

[0108] A chip disassembly fixture provided by the present application facilitates the separation of the bearing part and the chip 13 together from the housing of the ink cartridge 1, and then installs the disassembled bearing part and the chip 13 together into the installation part of a new ink cartridge, realizing the secondary utilization of the chip, improving the utilization rate of the chip, contributing to saving the cost of the chip, and having good environmental protection performance.

[0109] Embodiment III

[0110] This embodiment provides another chip disassembly fixture. The difference between this embodiment and Embodiment I is that the structures of the fixture components and the disassembly part in this embodiment are different from those of the fixture components and the disassembly part in Embodiment I.

[0111] As Figure 27 shown, the fixture component 60 includes a positioning part 21 and an assembly part 70. The positioning part 21 is provided with a positioning groove 61. The assembly part 70 is movably arranged on the positioning part 21, and the assembly part 70 is movably located between the positioning groove 61 and the force application part 40. The disassembly part 30 is inclinedly installed on the assembly part 70, so that the disassembly part 30 forms an inclined disassembly path during the movement process, and this inclined disassembly path extends along the axial direction of the force application part 40. When the force application part 40 applies pressure to the assembly part 70 and pushes the assembly part 70 to move towards the direction close to the positioning groove 61, it can drive the disassembly part 30 to move towards the ink cartridge installed in the positioning groove 61 to realize the disassembly of the chip and the chip bearing part on the ink cartridge.

[0112] Referring to Figure 28 and Figure 29 shown, the positioning part 21 is further provided with a sliding groove 62. The sliding groove 62 penetrates the positioning part 21 in the height direction, and the sliding groove 62 is arranged on both sides of the positioning groove 61 and has a certain distance from the positioning groove 61. The sliding groove 62 is arranged close to the assembly part 70.

[0113] Furthermore, the assembly part 70 includes a moving part 71, a joint part 72 and a clamping convex part 713. The clamping convex 713 is connected to the moving part 71, and the clamping convex part 713 is slidably and cooperatively connected with the sliding groove 62. Specifically, the clamping convex part 713 is in an "L" shape, and one end thereof has a clamping abutting surface 713a. The clamping abutting surface 713a abuts against the bottom surface of the sliding groove 62, so that the clamping convex part 713 can move in the sliding groove 62. The moving part 71 is used for assembling the disassembly part 30, and the joint part 72 is connected to the moving part 71, so that the disassembly part 30 is clamped between the moving part 71 and the joint part 72.

[0114] In this embodiment, the assembly part 70 is provided with an inclined installation surface, and the disassembly part 30 is installed on this inclined installation surface. Specifically, the moving part 71 can be provided with an inclined installation surface, and its inclined state extends obliquely upward away from the force application part along the axial direction of the force application part, and the disassembly part 30 is installed on the inclined installation surface of the moving part 71.

[0115] In some other embodiments, the disassembly portion 30 may also be arranged to be inclined, or the blade head on the disassembly portion 30 may be arranged to be inclined, so that the movable portion 71 may be provided with an inclined mounting surface or not, as long as the final inclined shape is ensured to be the same as the inclined shape of the above-mentioned movable portion 71, that is, the disassembly may be carried out according to the above-mentioned inclined preset path, and there is no limitation here.

[0116] like Figure 30 and Figure 31 As shown, the assembly portion 70 also includes an abutment portion 715, which is arranged away from the positioning portion 61, and the abutment portion 715 connects the moving portion 71 together, and can abut against the force-applying portion 40. Under the action of the force-applying portion 40, the assembly portion 70 moves on the clamp component 60.

[0117] Furthermore, the assembly portion 70 further includes a fourth limiting portion 714. When the assembly portion 70 is mounted on the clamp component 60, the fourth limiting portion 714 is arranged opposite to the positioning groove 61, and the fourth limiting portion 714 is arranged between the positioning groove 61 and the abutting portion 715. In some other embodiments, the fourth limiting portion 714 can also be arranged on the end surface of the abutting portion 715 facing the positioning groove 61. A second limited portion 63 is also arranged on the positioning groove 61 in the direction of the fourth limiting portion 714, and the second limited portion 63 can abut against the fourth limiting portion 714 to limit the moving distance of the moving portion 71 on the clamp component 60.

[0118] Continue to refer to Figure 30 As shown, the assembly portion 70 further includes a contact portion 712, which is disposed on the other side of the moving portion 71 away from the abutment portion 715, and the contact portion 712 is disposed approximately in a plane, and the contact portion 712 is disposed in a square shape, and the engaging protrusion 713 is disposed on the contact portion 712 protruding downward, and is disposed close to the fourth limiting portion 714, which penetrates the contact portion 712 in the height direction. The contact portion 712 contacts the upper end surface of the clamp component 60 and can move on the clamp component 60.

[0119] In this embodiment, a convex rib structure can be provided in the positioning groove 61, and the convex rib is provided at a position close to the second limited portion 63, and has a higher height close to one end of the second limited portion 63; the disassembly portion can also be arranged upwardly tilted, and can also be arranged into other structures, as long as the chip and the chip carrier can be disassembled.

[0120] like Figure 32 As shown, in this embodiment, when the disassembly fixture is used:

[0121] First, place the ink cartridge upside down within the positioning portion 61 on the fixture member 60 such that the chip faces upward and is adjacent to the disassembly portion. The ink cartridge 1 is exposed within the positioning portion 61, and the ink cartridge is stably positioned on the fixture member 60 through the positioning portion 61.

[0122] Rotate the handle of the force - applying portion, and the rotary driving member moves on the fixture member 60, pushing the assembly portion 70 fixedly provided with the disassembly portion, such that the cutter head of the disassembly portion 30 disassembles the chip and extends into the housing of the ink cartridge, i.e., the carrying portion where the chip is located. Continue to rotate the force - applying portion 40, pushing the assembly portion 70 to continue moving until the fourth limiting portion 714 abuts against the second portion to be limited 63, and the handle cannot be rotated. The disassembly portion cuts off the carrying portion where the chip is located, and the chip and the chip - carrying portion are disassembled from the housing of the ink cartridge.

[0123] Finally, install the disassembled chip or the chip and the chip - carrying portion on the chip - mounting portion of a new ink cartridge.

[0124] Among them, fixing the ink cartridge within the positioning portion or providing an elastic engagement portion within the positioning portion to achieve the effect of positioning the ink cartridge helps improve the accuracy of disassembling the edge position of the carrying portion.

[0125] Embodiment 4

[0126] This embodiment provides another chip disassembly fixture. The structure of this embodiment is basically the same as that of Embodiment 3, except that when disassembling the chip and the chip - carrying portion on the ink cartridge, the ink cartridge and the disassembly component move together.

[0127] As Figure 33 and Figure 34 shown, the chip disassembly fixture includes a fixture member 60, a disassembly portion 30, and a force - applying portion 40. The fixture member 60 includes a positioning portion 21 and an assembly portion 70. The positioning portion 21 is provided with a positioning groove 61, and the length of the positioning groove 61 is greater than the length of the ink cartridge 1. When the ink cartridge 1 is installed into the positioning groove 61, the ink cartridge 1 can move left and right within the positioning groove 61. The assembly portion 70 is detachably installed on the positioning portion 21 and is located between the positioning groove 61 and the force - applying portion 40, and can move on the fixture member 60 under the action of the force - applying portion 40. As Figure 35 shown, the assembly portion 70 includes a moving portion 71 and a joining portion 72. The moving portion 71 is slidably connected to the positioning portion 21 and can move on the positioning portion 21. The joining portion 72 is joined to the moving portion 71 and is used to fix the disassembly portion 30. The disassembly portion 30 is provided between the moving portion 71 and the joining portion 72.

[0128] In this embodiment, the assembling part 70 is provided with an inclined mounting surface, and the disassembling part 30 is mounted on this inclined mounting surface. Specifically, the moving part 71 can be provided with an inclined mounting surface, and its inclined state can be the same as that of the inclined mounting surface of the moving part described in Embodiment III. The disassembling part 30 is mounted on the inclined mounting surface of the moving part 71.

[0129] The fixture member 60 is further provided with a screw hole 62, and the screw hole 62 is provided at one end of the fixture member 60 away from the positioning groove 61. The assembling part 70 is arranged between the screw hole 62 and the positioning groove 61, and the screw hole 62 cooperates with the force applying part 40 so that the force applying part 40 can rotate and move within the screw hole 62.

[0130] As Figure 36 shown, the positioning groove 61 has a first end 61a and a second end 61b. The first end 61a is close to the assembling part 70, and the second end 61b is far from the assembling part 70. When the ink cartridge 1 is installed into the positioning groove 61, the side end of the ink cartridge is close to the first end 61a, and the position where the chip on the ink cartridge is located is close to the disassembling part 30 on the assembling part 70.

[0131] Furthermore, the position where the ink cartridge 1 is installed in the positioning groove 61 is not unique. The ink cartridge can abut against the first end 61a of the positioning groove 61, or can abut against the second end 61b of the positioning groove 61, or can be placed between the first end 61a and the second end 61b. When disassembling the chip and the chip carrier, rotate the force applying part 40, and the force applying part 40 pushes the assembling part 70 to move towards the ink cartridge. When the assembling part 70 abuts against the ink cartridge, if the ink cartridge 1 does not abut against the second end 61b of the positioning groove, rotate the force applying part 40 again, and the ink cartridge will move together with the combining part 70 until the ink cartridge abuts against the second end 61b of the positioning groove. Continue to rotate the force applying part 40, and the disassembling part 30 will disassemble the chip and the chip carrier on the ink cartridge until the chip and the chip carrier are disassembled.

[0132] In addition, an elastic member (not shown in the figure) can be further provided on the second end 61b of the positioning groove 61. The elastic member is arranged towards the first end 61a, one end of which is connected to the second end 61b, and the other end is suspended. When the ink cartridge is installed into the positioning groove 61, the side end of the ink cartridge can abut against the elastic member, and under the action of the force applying part 40, the assembling part 70 and the ink cartridge will move together in the direction of compression of the elastic member. At this time, the elastic member is compressed. When the compression force of the elastic member is large enough, it will push the ink cartridge towards the assembling part 70, that is, the chip and the chip carrier on the ink cartridge move towards the disassembling part 30. In this way, the disassembling part 30 can disassemble the chip and the chip carrier faster under the dual action of the elastic force and the rotational force. The elastic member can be a spring, a compression spring or a spring sheet, etc. There is no limitation here. Refer to Figure 37 shown.

[0133] In some other embodiments, to make it easier to disassemble the chip on the ink cartridge, the disassembly part 30 can be inclined or horizontally arranged. When the disassembly part is horizontally arranged, a cutting part for disassembling the chip and the chip carrier part from different directions needs to be provided on the fixture part. When the chip and the chip carrier part are disassembled horizontally by a certain distance, they are cut from the top along the height direction; the cutting part can also be set as a separate component (such as scissors), and when the chip and the chip carrier part are disassembled horizontally by a certain distance, the connection with the ink cartridge housing is directly cut off; alternatively, the cutting part can be not provided, and the chip and the chip carrier part are disassembled by bending. Through the above settings, it is convenient for the chip and the chip carrier part to be separated from the housing of the ink cartridge.

[0134] The ink cartridge chip disassembly fixture of the present application disassembles the chip and the chip carrier part on the ink cartridge by setting an inclined disassembly path on the fixture part and disassembling the chip and the chip carrier part along the inclined disassembly path, so that the chip and the chip carrier part are separated from the ink cartridge housing. The structure is simple and the operation is convenient, solving the problem of difficult operation in the process of disassembling the chip on the ink cartridge in the prior art, shortening the disassembly time, improving the disassembly efficiency, saving time and effort, and the chip disassembly fixture has a relatively simple structure, and the manufacturing difficulty and manufacturing cost are also relatively low, greatly improving the reusability of the chip.

[0135] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed in the present application should be covered by the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
