When the chip holder 300 is mounted on the chip receiving portion 130, the chip 200 carried on the chip holder 300 can face away from one end of the drum frame 121 (i.e., in the A1 direction), so as to facilitate the chip 200 to abut against and be electrically connected to the imaging device. The chip receiving portion 130 is provided with a first positioning portion 131, a second positioning portion 132, and a engaging portion 133. In the second direction, the first positioning portion 131 is located at one end of the chip receiving portion 130 in the B1 direction, the engaging portion 133 is located at one end of the chip receiving portion 130 in the B2 direction, and the second positioning portion 132 is disposed close to the engaging portion 133.

[0068] As Figure 10 shown, the chip holder 300 is provided with a chip mounting portion 330, a first positioned portion 310, a second positioned portion 320, and a notch portion 360. The chip mounting portion 330 protrudes on the side surface of the chip holder 300 in the A1 direction. The chip mounting portion 330 is disposed close to one side of the chip holder 300 in the B2 direction in the second direction, and the side surface of the chip mounting portion 330 in the B2 direction is flush with the side surface of the chip holder 300 in the B2 direction; in the third direction, the chip mounting portion 330 is located at a substantially middle position of the chip holder 300. A chip mounting groove for mounting the chip 200 is recessed on the surface of the chip mounting portion 330 in the A1 direction. The chip 200 can be fixed in the chip mounting groove by means of pasting, clamping, welding, etc., so that the chip 200 is mounted on the chip holder 300. The chip mounting portion 330 is further provided with electrical contact guiding ribs 340.

[0069] Refer to Figures 8 to 12, the first positioned part 310 is arranged on one side of the chip holder 300 in the B1 direction, the second positioned part 320 is arranged close to one side of the chip holder 300 in the B2 direction, and the first positioned part 310 cooperates with the first positioning part 131, and the second positioned part 320 is adapted to the second positioning part 132, so as to position the chip 200 on the chip accommodating part 130.

[0070] Reference Figure 8 , the first positioning part 131 is a positioning hole arranged on the chip accommodating part 130, and the second positioning part 132 is a first positioning protrusion arranged on the chip accommodating part 130. Preferably, the positioning hole is a round hole arranged on the chip accommodating part 130, and it penetrates the drum frame 121 along the first direction (A1 and A2 directions); the first positioning protrusion is a substantially cuboid bump arranged on the chip accommodating part 130, and it protrudes from the surface of the chip accommodating part 130 along the direction away from the box body 100 (A1 direction). Optionally, the positioning hole and the first positioning protrusion can also be other geometric shapes, and the present application does not limit this.

[0071] Reference Figures 10 to 12 , the first positioned part 310 and the second positioned part 320 are arranged on the same side surface (the side surface in the A2 direction) of the chip holder 300. The first positioned part 310 is a positioning column arranged on the chip holder 300. The positioning column is arranged on the surface of the chip holder 300 facing the box body 100 (the surface along the A2 direction) and protrudes along the A2 direction. The positioning column is a cylindrical positioning column arranged on the chip holder 300, and its diameter is slightly smaller than the diameter of the positioning hole (the first positioning part 131). The second positioned part 320 is a positioning groove arranged on the chip holder 300. The positioning groove is a groove recessed on the surface of the chip holder 300 facing the box body 100, and its shape is slightly larger than the size of the first positioning protrusion. When the chip 200 is installed on the chip holder 300, the positioning groove and the chip 200 are located on opposite side surfaces of the chip holder 300. That is, in the first direction, the chip 200 faces away from the box body 100, and the positioning groove faces the box body 100. When the chip holder 300 is installed on the chip accommodating part 130, the positioning column on the chip holder 300 is inserted into the positioning hole, and the positioning groove is sleeved on the first positioning protrusion, so as to accurately position the chip holder 300 on the chip accommodating part 130 on the processing box.

[0072] Such as Figure 6 、 Figures 8 to 12As shown, after the chip holder 300 is positioned within the chip receiving portion 130, it is also necessary to cooperate the notch portion 360 with the engaging portion 133 on the chip receiving portion 130 to fix the chip holder 300 within the chip receiving portion 130. Specifically, the notch portion 360 is a side notch provided on the side of the chip holder 300 in the B2 direction. The notch portion 360 is recessed along the B1 direction. The notch portion 360 is generally a rectangular groove. A transverse protrusion 361 is provided within the notch portion 360. The transverse protrusion 361 extends along the third direction and extends from one side in the C1 direction of the notch portion 360 to approximately the middle position of the notch portion 360 along the C2 direction. The transverse protrusion 361 is located on the side in the A2 direction of the notch portion 360 in the first direction. The side surface of the transverse protrusion 361 in the A1 direction is an engaging surface 363 for engagement. There is a certain distance between the engaging surface 363 and the side surface of the notch portion in the A1 direction.

[0073] As Figure 6 , Figure 8 , Figure 9 shown, the engaging portion 133 is a snap structure provided on the chip receiving portion 130. The snap structure is partially inserted into the notch portion 360 and engages with the engaging surface 133 of the transverse protrusion 361, thereby fixing the chip holder 300 on the chip receiving portion 130. Specifically, the engaging portion 133 (snap structure) is rotatably provided on the chip receiving portion 130. Pivot holes 1333 are provided on both the chip receiving portion 130 and the engaging portion 133. After the pivot holes of the two are aligned, the engaging portion 133 is installed on one side (the side in the B2 direction) of the chip receiving portion 130 through the rotating shaft 134 sequentially passing through the pivot holes 1333 and can rotate along the rotating shaft 134. The rotating shaft 134 extends along the third direction (i.e., the rotation axis of the engaging portion 133 is along the C1 and C2 directions). The pivot hole of the engaging portion 133 is opened at one end (the end in the A2 direction). A hook 1331 is provided at the other end (the end in the A1 direction) of the engaging portion 133. The hook 1331 is used to engage the transverse protrusion 361 within the notch portion 360. The engaging portion 133 can rotate around the rotation axis between the positions where the hook 1331 engages and disengages. Optionally, the rotating shaft can also be fixedly provided on one of the engaging portion 133 and the chip receiving portion 130, and a mating pivot hole is provided on the other, which can also achieve the rotational cooperation between the two.

[0074] Furthermore, a mounting post 1332 is provided on one end (the end in the A2 direction) of the engaging portion 133. When the engaging portion 133 is installed in the chip accommodating portion 130, an elastic member (not shown) is provided between the chip accommodating portion 130 and the engaging portion 133. One end of the elastic member (such as a spring) can be sleeved on the mounting post 1332 of the engaging portion 133, and the other end abuts against the chip accommodating portion 130, so that the elastic member can exert an elastic force on the engaging portion 133. When in use, the engaging portion 133 (snapping structure) is pried open to overcome the elastic force and rotate on the chip accommodating portion 130 to a position where the hook 1331 is disengaged. When the engaging portion 133 is not pried open, the engaging portion 13 is located at a position where the hook 1331 can clamp the chip frame 300 under the elastic force of the elastic member (engaged with the lateral protrusion 361 in the notch portion 360).

[0075] During the process of installing the chip rack 300 to the chip accommodating portion 130, the engaging portion 133 is first bend to overcome the elastic force and rotate, and then the chip rack 300 is accurately positioned on the chip accommodating portion 130 on the processing box by cooperating the positioning column on the chip rack 300 with the positioning hole on the chip accommodating portion 130 and the positioning protrusion with the positioning groove on the chip rack 300. Then, the snap structure is released, so that the engaging portion 133 is engaged with the engaging surface 363 of the transverse protrusion 361 in the upper notch portion 360 on the side of the chip rack 300 under the action of elastic force, and the chip rack 300 is fixed on the chip accommodating portion 130, so that the chip 200 removed from the old processing box can be installed on the new processing box.

[0076] In some other embodiments, the snap-fitting portion 133 is a fixed snap-fit, that is, it cannot rotate relative to the chip accommodating portion 130. The snap-fitting portion 133 may be an elastic snap-fit, which may clamp the lateral protrusion 361 under its own elastic action, so that the chip frame 300 may also be smoothly installed and fixed. Preferably, the snap-fitting structure may be an integrally formed structure with the chip accommodating portion 130.

[0077] refer to Figure 13 and Figure 14 In some other embodiments, a pivot hole 1333 is provided at one end of the snap-fit ​​portion 133. The pivot hole 1333 is preferably a bar-shaped hole. The rotating shaft 134 passes through the bar-shaped hole and is installed on the chip receiving portion 130, so that the snap-fit ​​portion 133 can have a certain space to move in the radial direction (the direction intersecting the axis of rotation) while rotating. The chip receiving portion 130 is also provided with a slot 135. When the snap-fit ​​structure is installed in the chip receiving portion 130, the mounting column 1332 can be inserted into the slot 135. When in use, the mounting column 1332 is moved diagonally ( Figure 13The engaging portion 133 is moved along the P direction, the P direction intersecting the first direction and the second direction, so that the engaging portion 133 rotates and moves on the chip accommodating portion 130, and the mounting post 1332 on the engaging portion 133 moves in the direction of disengaging from the slot 135, so that the hook 1331 is disengaged from the transverse protrusion 361 in the notch 360 of the chip frame 300; and when the engaging portion 133 is not moved, the mounting post 1332 is clamped in the slot 135, so that the engaging portion 133 is in the position of the hook 1331 (along the Figure 13 The chip rack 300 is clamped in the N direction, where the N direction is parallel to the first direction.

[0078] In some other embodiments, in order to further fix the chip rack 300 on the chip rack 300 accommodating portion, the snap-fitting portion 133 may also be a backing adhesive provided on the chip rack 300 or the chip rack 300 accommodating portion, so that the chip rack 300 and the chip accommodating portion 130 are fixed by adhesion with the backing adhesive instead of being fixed by a snap-fit ​​structure.

[0079] In this embodiment, when the processing box chip frame 300 and the chip 200 are recycled and used again:

[0080] First, on the recycled processing box, the engaging portion 133 is moved to disengage the hook 1331 of the engaging portion 133 from the transverse protrusion 361 of the notch 360 on the chip frame 300 , and then the chip frame 300 and the chip 200 are pulled out in a direction away from the box body 100 .
