Description

[Technical field]

[0001] The present invention relates to the field of electronic imaging technology, and in particular to a method for remanufacturing a processing box and a regenerated processing box obtained by using the method. [Background technology]

[0002] The process cartridge is a detachable part widely used in electronic imaging devices. The electronic imaging device is provided with a driving member for providing power to the process cartridge; a detection component is also provided on the process cartridge. When a new process cartridge is installed on the electronic imaging device, the electronic imaging device recognizes it as a specific process cartridge through the action of the detection component and the electronic imaging device, and recognizes the process cartridge according to the information preset in the electronic imaging device, thereby reminding the user to replace the new process cartridge in time.

[0003] In addition, in order to make the electronic imaging device use only its own processing box, the device manufacturer also sets a chip on the processing box that is connected to the electronic imaging device's electrical signal. Now, taking a specific processing box as an example, Figure 1 The figure shows a processing box in the prior art.

The material of the developing roller 14 can be, for example, elastic rubber and a metal shaft core or a conductive resin.

[0040] A handle 171 is provided on the other side of the process cartridge body 17 relative to the developing roller 14 in the third direction.

[0041] The detection component 11 includes a rotating member 111 and a detected member 112, and is used for the imaging device to identify the processing box and to receive the rotational driving force from the power receiving component 19 to work.

[0042] A support frame 13 is provided at the second end of the processing box body 17 in the first direction, and the support frame 13 is used to install the chip assembly 12. Specifically, the support frame 13 is located on the opposite side of the processing box body 17 relative to the protective cover 15 in the first direction, and the support frame 13 is detachably fixed to the protective cover 15, and specifically, it can be connected with the protective cover 15 by snapping.

[0044] The chip 20 has an electrical contact surface 201 and another surface arranged opposite to the electrical contact surface. In a second direction intersecting both the first direction and the third direction, the chip 20 is fixed on a chip fixing member 121 , and the chip fixing member 121 is connected to an elastic support member 123 via an elastic member 122 .

[0045] The chip fixing member 121 is located on a side away from the processing box body 17 in the second direction, and has a chip fixing surface 1211, a first groove 1213, and a second groove 1215. The chip fixing surface 1211 is provided at one end of the chip fixing member 121 in the second direction, and the other end of the chip fixing member 121 in the second direction is provided with an opening and a cavity inside, and a first protrusion is provided in the cavity to cooperate with the elastic member 122 to fix one end of the elastic member 122. When one end of the elastic member 122 is fixed to the first protrusion, at least a part of the elastic member 122 is located in the cavity of the chip fixing member 121.

The limiting pillars 1217a and 1217b are inserted into the first through hole 151, and the limiting pillar 1217c is inserted into the second through hole 131, so that the chip assembly can be moved in the first direction, the second direction, and the third direction respectively (move within the size range of the first through hole 151 and the second through hole 131).

[0046] The elastic support member 123 is provided with an opening at one end close to the chip fixing member 121 in the second direction and has a cavity inside. A second protrusion 1232 is provided in the cavity to cooperate with the elastic member 122 to fix the other end of the elastic member 122. Two clamping parts 1231 are provided on the elastic support member 123. The two clamping parts 1231 are symmetrically arranged on both sides of the elastic support member 123 in the first direction. The two clamping parts 1231 are respectively clamped and connected with the second grooves 1215 symmetrically arranged on the chip fixing member 121, so that the elastic member 122 is always in a pressed state in the second direction.

[0047] The elastic member 122 may be a compression spring, or a tension spring, a spring sheet, an elastic rubber, an elastic sponge, etc. The elastic expansion and contraction direction of the elastic member 122 may be set along the second direction.

[0048] The steps of the remanufacturing method of the recycled processing box are described below. A remanufacturing method of a processing box specifically includes the step of remanufacturing the chip assembly of the processing box. After the support frame 13 of the chip assembly is removed from the processing box 1, the chip assembly 12 can be easily removed. Then the remanufacturing step of the chip assembly is described.

[0049] Figure 8 is a flow chart showing the remanufacturing method of the chip assembly. In addition, the manufacturer can perform the following processing by manual operation or automated device. When recycling and remanufacturing the chip assembly, first, remove the chip fixing part 121, the elastic part 122, the elastic support part 123, and the chip 20 of the chip assembly 12 (step S1). Secondly, the first groove 1213 of the chip fixing surface 1211 on the chip fixing part 121 in the second direction relative to a side surface of the chip 20 is machined. The machining method can be drilling or milling to penetrate the first groove 1213 and cut off the rib 1212 together to form a through hole 1216 extending in the second direction (step S2). The structure of the chip fixing part 121 after machining is as shown in FIG. Fig. 9 and Fig.10 Finally, a new chip 30 is installed at the same position of the chip fixing surface 1211 of the chip fixing member 121 having the through hole 1216 after machining, as shown in FIG. Fig.11 Then, one end of the elastic member 122 is fixed to the first protrusion 1214 of the chip fixing member 121, and the other end is connected to the second protrusion 1232 of the elastic support member 123. The two symmetrically arranged snap-fitting portions 1231 on the elastic support member 123 are respectively snap-fitted into the two symmetrically arranged second grooves 1215 of the chip fixing member. (Step S3), as shown in FIG. Fig.12 shown.

[0050] In addition, the chip 20 of the chip assembly 12 may be removed (step S1). The first groove 1213 of the chip fixing surface of the chip fixing part 121 is machined, and the machining method may be drilling or milling, so that the first groove 1213 is penetrated, and the rib 1212 is cut off together to form a through hole 1216 extending in the second direction (step S2). A new chip 30 is installed at the same position of the chip fixing surface 1211 on the chip fixing part 121 having the through hole 1216 (step S3). The thickness of the new chip 30 in the second direction may be greater than that of the original chip 20, and a part of the new chip 30 will be embedded in the through hole 1216.

[0051] Furthermore, the manufacturer rewrites the information or data of the removed chip 20, so that the chip 20 can be reconnected or recognized by the electronic imaging device when it is working. Afterwards, the rewritten or rewritten chip 20 that is checked to be normal is installed on the machined chip fixture 121 (step S3).

[0052] In addition, if Fig.13 As shown, the remanufacturing method of the processing box also includes a process box body remanufacturing step, when the processing box body 17 is recycled, after remanufacturing, such as replacing new parts, filling the developer, resetting the detection component 11, etc., (step S4). It also includes an assembly step, after the processing box body and the chip assembly are remanufactured, the remanufactured chip assembly 12 together with the chip assembly fixing support frame 13 are assembled to the remanufactured processing box body, (step S5). In this way, the recycling and remanufacturing of the entire processing box is completed.

[0053] Preferably, in order to save resources, a reusable chip partial structure can also be designed, and the chip fixing part 121 is machined to penetrate the first groove 1213. After the rib 1212 is cut off, a through hole 1216 is formed to reserve space for the new chip 30. Whether a new chip or a rewritten chip, or even other types of chips are used, they can be installed in the machined chip fixing part 121, so that the regenerated processing box can be compatible with the use of multiple chips, thereby improving the versatility of the regenerated processing box, realizing the recycling and reuse of processing box and chip component resources, saving resources and reducing waste.
