Description

Technical Field

[0001] The invention relates to the technical field of printing consumables used in laser printers, and in particular to an electronic imaging device of a processing box. Background Art

[0002] In electronic imaging equipment, such as electrostatic copiers or digital copiers and all-in-one printers, a process cartridge containing toner is provided, see Figures 1 to 3 An existing processing box includes a drum frame 10 and a developing frame 15, wherein a first end wall 11 is provided at one end of the drum frame 10, and a second end wall 16 is provided at one end of the developing frame 15. A photosensitive drum 13 is mounted on the drum frame 10, and a developing roller 18 is mounted on the developing frame 15. When the processing box is installed in an electronic imaging device for operation, the electronic imaging device needs to supply power to the developing roller 18. For this purpose, a conductive member 20 is provided in the processing box, and a conductive protrusion 21 is provided on the conductive member 20. In order to reduce the volume of the processing box, the conductive member 20 is arranged between the first end cover 11 of the drum frame 10 and the second end wall 16 of the developing frame 15.

[0003] from Figure 3 It can be seen that the first end wall 11 of the drum frame 10 is the outermost end wall of the processing box, that is, the end wall close to the electronic imaging device, so the conductive protrusion 21 needs to extend to the first end wall 11 so as to be electrically connected to the conductive terminal on the electronic imaging device. To this end, a through hole 14 is provided on the first end wall 11, and the conductive protrusion 21 protrudes toward the first end wall 11 and is penetrated in the through hole 14, so that the outer wall of the conductive protrusion 21 is exposed to the first end wall 11. In order to save the production cost of the conductive member 20, the existing conductive protrusion 21 is integrally formed and arranged on the conductive member 20.

[0004] Since the positions and shapes of the conductive terminals in different types of electronic imaging devices are different, the positions and shapes of the conductive protrusions 21 of the process boxes adapted to different types of electronic imaging devices are also different, which results in the need to use conductive members 20 of different structures for process boxes of different types. For the manufacturer of process boxes, it is necessary to equip the conductive members 20 of different types, which increases the production cost of the process boxes on the one hand, and on the other hand, since the conductive members 20 of different structures are only different in the shape of the conductive protrusions 21, it also leads to waste in the production of the conductive members 20.

[0005] In addition, the design of the conductive protrusion 21 and the conductive member 20 being integrally formed also brings difficulty to the assembly of the processing box. Since the conductive member 20 is installed between the first end wall 11 and the second end wall 16, and the through hole 14 is provided on the first end wall 11, the conductive protrusion 21 needs to be inserted into the through hole 14. Therefore, when assembling the processing box, the conductive member 20 is usually fixed to the developing frame 15 first, and then the drum frame 10 is installed on the developing frame 15. At this time, the first end wall 11 will be blocked by the conductive protrusion 21, and a large force is required to install the drum frame 10. In addition, the first end wall 11 may scratch the conductive protrusion 21 during the installation process, which affects the connection stability between the conductive protrusion 21 and the conductive terminal of the electronic imaging device. Summary of the invention

[0006] A first object of the present invention is to provide a processing box that is easy to assemble and can easily replace conductive parts.

[0007] A second object of the present invention is to provide an electronic imaging device using the above-mentioned processing box.

[0008] In order to achieve the first purpose of the present invention, the processing box provided by the present invention includes a developing frame and a drum frame, a developing roller is arranged in the developing frame, a photosensitive drum is arranged in the drum frame, the drum frame has a first end wall, the developing frame has a second end wall, and a conductive bracket is arranged between the first end wall and the second end wall; wherein a detachably connected conductive part is arranged on the conductive bracket, and the conductive part protrudes from a side of the conductive bracket close to the first end wall.

[0009] It can be seen from the above scheme that the conductive part can be detachably mounted on the conductive bracket. When assembling the processing box, the drum frame, the conductive bracket and the developing frame can be assembled first, and finally the conductive part can be installed on the conductive bracket. In this way, when assembling the drum frame, the conductive part will not interfere with the drum frame, which is convenient for assembling the processing box. In addition, since the conductive part is detachably mounted on the conductive bracket, conductive parts of different shapes can be replaced according to different types of processing boxes. After replacing the conductive parts, the processing box can be compatible with different types of electronic imaging devices, thereby improving the compatibility of the processing box. The processing box manufacturer does not need to prepare a large number of conductive brackets, but only needs to prepare conductive parts of different shapes, thereby reducing the production cost of the processing box.

[0010] A preferred solution is that a first through hole penetrating the first end wall is provided on the first end wall, and the conductive member is inserted into the first through hole.

[0011] It can be seen from this that the outer end surface of the conductive member can be exposed on the first end wall, so as to facilitate the electrical connection between the conductive member and the conductive terminal of the electronic imaging device.

[0012] A further solution is that the first through hole is located at a top corner of the first end wall, and at least a portion of a peripheral wall of the first through hole is an outer peripheral wall of the first end wall.

[0013] It can be seen that the first end wall is not provided with an opening but with a through hole, thereby improving the strength of the first end wall.

[0014] A further solution is that the conductive bracket is provided with at least one first mounting hole, and a contact portion is provided on a side of the first mounting hole close to the second end wall; the conductive member is provided with at least one mounting pin, and a snap-fit ​​portion is provided at the end of the mounting pin, the mounting pin passes through the first mounting hole, and the snap-fit ​​portion abuts against the abutment portion.

[0015] It can be seen that the conductive member and the conductive bracket are connected through the first mounting hole and the mounting pin, which can facilitate the installation and removal of the conductive member.

[0016] A further solution is that the conductive bracket is provided with at least one positioning hole, and at least one positioning column is provided on the end surface of the conductive member close to the conductive bracket, and the positioning column is inserted into the positioning hole.

[0017] It can be seen that the positioning of the conductive component on the conductive bracket is achieved through the cooperation between the positioning column and the positioning hole, thereby improving the position accuracy of the conductive component assembly.

[0018] An optional solution is that a second mounting hole is provided on the conductive bracket; the conductive member includes a conductive contact portion and a connecting portion, and the connecting portion can be detachably inserted into the second mounting hole.

[0019] A further solution is that the conductive contact portion is arranged in a strip shape, and the connecting portion is arranged at one end of the conductive contact portion.

[0020] A further solution is that a second through hole penetrating the first end wall is provided on the first end wall, the connecting portion passes through the second through hole, and the conductive contact portion is located on an end surface of the first end wall away from the conductive bracket.

[0021] It can be seen that the connecting portion of the conductive member can pass through the first end wall and be inserted into the conductive bracket, thereby achieving the connection and fixation between the conductive drum frame and the conductive bracket, and the assembly of the drum frame and the conductive bracket is simpler.

[0022] A further solution is that a third mounting hole is provided on the second end wall, and a mounting column is provided on one side of the conductive bracket close to the third mounting hole, and the mounting column is inserted into the third mounting hole.

[0023] It can be seen that the fixed cooperation between the developing frame and the conductive bracket can be achieved through the cooperation between the third installation hole and the installation column.

[0024] To achieve the second objective of the present invention, the electronic imaging device provided by the present invention includes a housing, a process cartridge installation cavity is provided in the housing, and the process cartridge installation cavity is installed with the above-mentioned process cartridge.

[0047] The present invention is further described below in conjunction with the accompanying drawings and embodiments. DETAILED DESCRIPTION

[0048] The electronic imaging device of the present invention can be a laser printer, and a processing box installation cavity is provided in the electronic imaging device. The processing box of the present invention can be installed in the processing box installation cavity. The processing box includes a drum frame and a developing frame, and is also provided with a conductive component.

[0049] Processing box first embodiment:

[0050] See also Figure 4 The process box of this embodiment has a drum frame 30 and a developing frame 40. A first end wall 31 is provided at one end of the drum frame 30, and a second end wall 41 is provided at one end of the developing frame 40. In the length direction of the process box, the first end wall 31 and the second end wall 41 are located at the same end of the process box, and there is a gap between the first end wall 31 and the second end wall 41. The conductive bracket 50 is arranged between the first end wall 31 and the second end wall 41. A developing roller 42 is installed on the developing frame 40, and the developing roller 42 can rotate along its own axis relative to the developing frame 40.

[0051] See also Figure 4 and Figure 5 , a conductive member 60 is mounted on the conductive bracket 50, and both the conductive bracket 50 and the conductive member 60 are made of conductive materials, such as conductive resin materials or conductive metal materials. Therefore, the conductive bracket 50 and the conductive member 60 constitute a conductive assembly of this embodiment. In this embodiment, the conductive member 60 is detachably mounted on the conductive bracket 50, see Figure 6The conductive bracket 50 is provided with two first mounting holes 51 and two positioning holes 55. Preferably, the first mounting hole 51 is a through hole, that is, the first mounting hole 51 passes through the two side surfaces of the conductive bracket 50, and the positioning hole 55 is a blind hole, that is, the positioning hole 55 does not pass through the two side surfaces of the conductive bracket 50.

[0052] See also Figure 7 The conductive member 60 is provided with two mounting pins 61, each of which extends downward from the conductive member 60 body, specifically, in a direction close to the conductive bracket 50. In addition, a buckle portion 62 is provided at the end of the mounting pin 61, and the mounting pin 61 can pass through the first mounting hole 51. Figure 8 and Fig. 9 A contact portion 56 is provided on one side of the first mounting hole 51 close to the second end wall 41 . When the conductive member 60 is mounted on the conductive bracket 50 , the buckling portion 62 of the mounting pin 61 abuts against the contact portion 56 , thereby achieving fixation between the conductive member 60 and the conductive bracket 50 .

[0053] In addition, two positioning posts 63 are provided on one side of the conductive member 60 close to the conductive bracket 50. Preferably, the two positioning posts 63 are symmetrically arranged on the conductive member 60. Moreover, after the conductive member 60 is installed on the conductive bracket 50, the positioning posts 63 are inserted into the positioning holes 55, so as to realize the positioning of the conductive member 60 and the conductive bracket 50. At the same time, through the cooperation of the two mounting pins 61 and the first mounting hole 51, and the cooperation of the two positioning posts 63 and the positioning holes 55, the conductive member 60 can be prevented from moving relative to the conductive bracket 50, and the stability of the conductive member 60 during use is ensured, so as to ensure that the current can be output from the conductive terminal of the electronic imaging device through the conductive member 60 and the conductive bracket 50 to the developing roller 42.

[0054] See also Figure 4 and Fig.10 A first through hole 32 is provided on the first end wall 31 of the drum frame 30, and after the process box is assembled, the conductive member 60 is inserted into the first through hole 32, so that the outer end surface of the conductive member 60 is exposed to the first end wall 31, so that the conductive member 60 can contact with the conductive terminal of the electronic imaging device. Fig.10 It can be seen that the first through hole 32 is located at the top corner of the first end wall 32, and a portion of the peripheral wall of the first through hole 32 is the outer peripheral wall of the first end wall 32. Therefore, the conductive bracket 50 does not form an opening at the top corner, which improves the strength of the conductive bracket 50.

[0055] See also Fig.11 and Fig.12, a mounting hole 46 is provided on the second end wall 41 of the developing frame 40, and a mounting post 56 is provided on the side of the conductive bracket 50 facing the second end wall 41. In addition, a mounting post 45 protruding toward the conductive bracket 50 is also provided on the second end wall 41, and a mounting hole 57 is provided on the conductive bracket 50. When the conductive bracket 50 is mounted to the developing frame 40, the mounting post 56 is inserted into the mounting hole 46, and the mounting post 45 is inserted into the mounting hole 57, so that the conductive bracket 50 and the developing frame 40 are fixed.

[0056] In addition, a through hole 48 is also provided on the second end wall 41 of the developing frame 40, and the roller shaft 43 of the developing roller 42 can pass through the through hole 48 and abut against the conductive bracket 50, so that the current output from the electronic imaging device can flow to the roller shaft 43 of the developing roller 42 after passing through the conductive part 60 and the conductive bracket 50.

[0057] When assembling the processing box, after fixing the conductive support 50 on the developing frame 40, the drum frame 30 is installed on the developing frame 40. At this time, the conductive support 50 is clamped between the first end wall 31 and the second end wall 41. Since the conductive member 60 is not installed on the conductive support 50, the installation of the drum frame 30 is very convenient. Then, the conductive member 60 is passed through the first through hole 32 and installed on the conductive support 50 to complete the assembly of the processing box. It can be seen that the installation of the conductive member 60 is very convenient and simple, which can improve the assembly efficiency of the processing box. In addition, since the conductive member 60 will not be scratched during the installation of the drum frame 30, it is beneficial to ensure the structural integrity of the assembled conductive member 60 and improve the product quality of the processing box.

[0058] On the other hand, the conductive members 60 of different structures and shapes can be selected according to the different types of electronic imaging devices, so that the assembled processing box can meet the needs of different types of electronic imaging devices. In this way, the manufacturer of the processing box only needs to prepare one conductive bracket 50 and prepare multiple different conductive members 60, but does not need to prepare multiple conductive brackets 50 of different structures, thereby reducing the reserve cost of raw materials and the overall production cost of the processing box.

[0059] Processing box second embodiment:

[0060] See also Figures 13 to 15The processing box of this embodiment has a drum frame 70 and a developing frame 80. A first end wall 71 is provided at one end of the drum frame 70, and a second end wall 81 is provided at one end of the developing frame 80. In the length direction of the processing box, the first end wall 71 and the second end wall 81 are located at the same end of the processing box, and there is a gap between the first end wall 71 and the second end wall 81. The conductive bracket 90 is arranged between the first end wall 71 and the second end wall 81. The drum frame 70 is mounted with a photosensitive drum 72, which can rotate along its own axis relative to the drum frame 70, and the developing frame 80 is mounted with a developing roller 82, which can rotate along its own axis relative to the developing frame 80.

[0061] See also Figures 16 to 18 The conductive bracket 90 is detachably mounted with a conductive member 100. The shape of the conductive member 100 of this embodiment is different from that of the conductive member of the first embodiment. Accordingly, the mounting hole of the conductive bracket 90 is also changed accordingly. A second mounting hole 91 is provided on the conductive bracket 90. Fig.17 It can be seen that the second mounting hole 91 is a circular through hole that penetrates the conductive bracket 90. The conductive member 100 includes a conductive contact portion 101 and a connecting portion 102. The conductive contact portion 101 is generally strip-shaped, and a conductive protrusion 105 is provided at the first end of the conductive contact portion 101. The connecting portion 102 is provided at the second end of the conductive contact portion 101. A spline 103 is provided at the free end of the connecting portion 102. The connecting portion 102 can be detachably inserted into the second mounting hole 91, and can be removed from the conductive contact portion 101. Fig.18 It can be seen that the spline 103 is interference-fitted with the second mounting hole 91 , thereby achieving the installation of the conductive member 100 and the conductive bracket 90 .

[0062] The conductive protrusion 105 protrudes in a direction away from the conductive bracket 90. On the assembled processing box, the conductive protrusion 105 is exposed outside the first end wall 71, so as to contact the conductive terminal of the electronic imaging device.

[0063] The conductive member 100 may be integrally formed or may be separated. For example, the conductive contact portion 101 and the connecting portion 102 are separated. If the conductive contact portion 101 and the connecting portion 102 are separated, the connecting portion 102 and the conductive contact portion 101 may be connected by a threaded connection, or a through hole may be provided in the conductive contact portion 101, and a mounting post may be provided at the end of the connecting portion 102, and the connection is achieved by interference fit between the mounting post and the through hole. This embodiment preferably uses an integrally formed method.

[0064] In this embodiment, the conductive contact portion 101 does not directly contact the conductive bracket 90. In fact, the conductive contact portion 101 and the conductive bracket 90 are respectively located on two sides of the first end wall 71. Fig.19, a second through hole 75 penetrating the first end wall 71 is provided on the first end wall 71, the second through hole 75 is a circular through hole, and the connecting portion 102 of the conductive member 100 can pass through the second through hole 75 and be inserted into the second mounting hole 91 of the conductive bracket 90. In addition, the conductive contact portion 101 is located on the end surface of the first end wall 71 away from the conductive bracket 90. In this way, the conductive member 100, the first end wall 71 and the conductive bracket 90 can be fixed by the connecting portion 102, so that the conductive member 100 has the function of connecting the first end wall 71 and the conductive bracket 90.

[0065] See also Fig.19 and Fig. 20 An opening 76 is provided at a top corner of the first end wall 71, and the conductive contact portion 101 of the conductive member 100 is located in the opening 76. In this way, the conductive contact portion 101 can be designed into different shapes without being restricted by the shape of the first end wall 71, thereby meeting the requirements for being applicable to different types of electronic imaging devices.

[0066] See also Fig.21 and Fig. 22 , a mounting hole 84 is provided on the second end wall 81 of the developing frame 80, and a mounting post 94 is provided on the side of the conductive bracket 90 facing the second end wall 81. In addition, a mounting post 85 protruding toward the conductive bracket 90 is also provided on the second end wall 81, and a mounting hole 95 is provided on the conductive bracket 90. When the conductive bracket 90 is mounted to the developing frame 80, the mounting post 94 is inserted into the mounting hole 84, and the mounting post 85 is inserted into the mounting hole 95, thereby achieving the fixing between the conductive bracket 90 and the developing frame 80.

[0067] In addition, a through hole 88 is provided on the second end wall 81 of the developing frame 80, and a roller shaft 83 ( Fig.15 The conductive member 100 (shown) can pass through the through hole 88 and abut against the conductive bracket 90, so that the current output from the electronic imaging device can flow to the roller shaft 83 of the developing roller 82 after passing through the conductive member 100 and the conductive bracket 90.

[0068] When assembling the processing box, after the conductive bracket 90 is fixed to the developing frame 80, the drum frame 70 is installed on the developing frame 80. At this time, the conductive bracket 90 is clamped between the first end wall 71 and the second end wall 81. Since the conductive member 100 is not installed on the conductive bracket 90, the installation of the drum frame 80 is very convenient. Then, the conductive member 100 is installed on the conductive bracket 90. Specifically, the connecting portion 102 of the conductive member 100 passes through the second through hole 75 of the first end wall 71 and is inserted into the second mounting hole 91 of the conductive bracket 90, and the assembly of the processing box is completed. In this embodiment, since the connecting portion 102 needs to pass through the second through hole 75 and be inserted into the second mounting hole 91, the second through hole 75 and the second mounting hole 91 are coaxially arranged, and further, the second through hole 75 and the second mounting hole 91 are connected to each other.
