[ technical field ] A method for producing a semiconductor device

The application relates to the technical field of printing, in particular to a power receiving part and a powder cylinder.

[ background of the invention ]

The powder cartridge is a replaceable consumable widely used in the field of electronic imaging, is used on an image forming apparatus and supplies developer to the image forming apparatus. An image forming apparatus is a device that forms an image on a recording material by an electrophotographic image forming process technology, such as: electrophotographic copies, laser printers, electrophotographic printers, facsimile machines, word processors, and the like.

The existing powder cartridge mainly comprises a cartridge body and a power receiving part. A large amount of developer is filled in the cylinder; the cylinder is generally cylindrical in structure. A power receiving member is generally provided on a side wall at one end in the longitudinal direction of the cylinder. The power receiving component is connected with the cylinder body. The power receiving member receives a rotational driving force from the image forming apparatus and transmits the rotational driving force to the other portion of the powder cartridge so that the powder cartridge can discharge the developer to the outside. A powder outlet of the powder cartridge for discharging the developer is usually located near or on the power receiving part.

A portion of the conventional image forming apparatus connected to the powder cartridge is a rotational driving force transmitting member of the image forming apparatus. The rotational drive force transmitting member is provided with a special structure having a needle-like means at the center of the rotational drive force transmitting member and substantially flush with the opening of the rotational drive force transmitting member. When the powder cartridge is mounted on the image forming apparatus, the rotational driving force transmitting member moves toward the powder cartridge, and the needle-like means of the rotational driving force transmitting member correspondingly penetrates deeply into the power receiving member. Then the pushing device surrounding the inner wall of the rotary driving force transmission part retracts along the direction far away from the powder cylinder, then the image forming device drags the powder cylinder to move towards the direction far away from the rotary driving force transmission part, the powder cylinder is opened, and the developer can flow out; when the image forming device stops imaging work and the powder cylinder is detached from the image forming device, the image forming device drags the powder cylinder to move towards the direction of the rotary driving force transmission part to close the upper opening of the powder cylinder, the pushing device surrounding the inner wall of the rotary driving force transmission part pushes towards the direction of the powder cylinder, the rotary driving force transmission part moves towards the direction far away from the powder cylinder, and at the moment, the powder cylinder can be taken out. Due to the reasons that the existing powder cylinder is poor in structural design, not standard in use, unqualified in production materials and the like, the rotary driving force transmission part cannot be meshed with the power receiving part or is easy to disengage after being meshed.

[ detailed description ] embodiments

Example one

The present embodiment provides a power receiving component, as shown in fig. 1 and fig. 2, including a movable portion 110, a receiving portion 120, a transmission portion 130, a first elastic member 150, and preferably, an elastic washer 140.

As shown in fig. 3, the transmission part 130 is provided with a protruding eave 131 and a protruding block 132. The transmission part 130 is connected with the powder cylinder body, and the inner wall of the powder cylinder body can be abutted against the outer wall of the transmission part 130 or the outer wall of the powder cylinder body can be abutted against the inner wall of the transmission part 130. The connection method includes, but is not limited to, thermoforming, gluing, riveting, and other prior art in mechanical industry, and is not described herein.

The receiving part 120 is provided with a receiving tooth 123, a support rod 124, a transmission rod 125, a drop-off prevention groove 126, a first locking tooth 122 and a second locking tooth 121. Wherein the receiving teeth 123 can receive a rotational driving force from the image forming apparatus; the support rod 124 has elasticity and can be deflected radially inwards along the rotating shaft of the powder cylinder body; the transmission rod 125 can abut against the convex block 132, so that the rotation driving force is transmitted from the receiving part 120 to the transmission part 130 and then to the powder cylinder body; the first and

second locking teeth

122 and 121 serve to prevent the receiving part 120 from being removed from the transmission part 130. When the powder cartridge normally operates in the image forming apparatus, the first locking tooth 122 just abuts against the ledge 131, or the first locking tooth 122 does not abut against the ledge 131 yet. The second locking tooth 121 is a backup measure for a safety measure when the first locking tooth 122 is broken or when the receiving portion 120 is pulled out of a position where the first locking tooth 122 abuts against the flange, and at this time, the second locking tooth 121 abuts against the flange to prevent the receiving portion 120 from being pulled out of the transmission portion 130 as a whole. Preferably, to ensure smooth separation of the receiving part 120 and the transmission part 130, the first and

second locking teeth

122 and 121 do not interfere with other parts of the transmission part 130. If a failure occurs in the image forming apparatus to prevent the entire receiving unit 120 from being pulled out of the driving unit 130, the quality of the printing operation may be deteriorated, the inside of the image forming apparatus may be damaged, and if the damaged powder cartridge is not properly disposed of, the health of the user may be deteriorated, or air and water may be polluted.

The movable portion 110 is provided with an abutting portion 111 and an urging portion 112. The contact portion 111 can contact the image forming apparatus and move the movable portion 110 in the direction of the rotational axis of the powder cartridge cylinder. The height of the radial projection of the abutting part 111 on the rotation axis of the powder cylinder is larger than that of the radial projection of the receiving tooth 123 on the rotation axis of the powder cylinder. The pushing part 112 can enter the anti-slip groove 126, and when the pushing part 112 is in the anti-slip groove 126, the supporting rod 124 cannot be shifted radially inward along the rotation axis of the powder cartridge barrel due to the movable part 110.

A first elastic member 150 is further provided between the movable portion 110 and the receiving portion 120. Preferably, the first elastic member 150 is a spring. The movable position of the movable portion 110 is limited by the receiving portion 120.

The process of loading the powder cartridge into the image forming apparatus is described in detail below. The movable member 998 of the image forming apparatus is located inside the rotational driving force transmitting member 999.

In the first step, as shown in fig. 4, when the powder cartridge is not loaded in the image forming apparatus, the urging portion 112 of the power receiving member is in the escape preventing groove 126, and the support rod 124 cannot be displaced radially inward along the rotational axis of the powder cartridge cylinder. The receiving portion 120 and the transmission portion 130 are in close contact with each other, so that the developer stored in the powder cartridge body cannot flow out. Preferably, an elastic gasket 140 is further disposed between the receiving portion 120 and the transmission portion 130 to improve sealing performance.

Second, after the powder cartridge is loaded into the image forming apparatus, since the radial distance between the abutting portion 111 and the rotational axis of the powder cartridge cylinder is greater than the radial distance between the receiving teeth 123 and the rotational axis of the powder cartridge cylinder, the movable member 998 on the image forming apparatus pushes the abutting portion 111 to move the movable portion 110 toward the powder cartridge cylinder, and the urging portion 112 is separated from the escape-preventing groove 126, as shown in fig. 5. The support rod 124 may now be biased radially inward along the axis of rotation of the cartridge barrel.

Third, the rotational driving force transmitting member 999 of the image forming apparatus moves in the direction of the cylindrical body of the powder cartridge. Due to the interference between the rotational driving force transmitting member 999 and the driving teeth 123, the support rods are displaced radially inward along the rotational axis of the powder cartridge barrel, and the receiving portion 120 is engaged with the rotational driving force transmitting member 999 as shown in fig. 6.

In the fourth step, the movable member 998 of the image forming apparatus moves in a direction away from the powder cartridge body. Due to the first elastic member 150, the movable portion 110 follows the movable member 998 to move away from the powder cartridge barrel until the pushing portion 112 is forced into the escape-preventing groove 126, as shown in fig. 7. At this time, the support rod 124 cannot be displaced radially inward along the rotational axis of the powder cartridge cylinder due to the abutting and pressing by the abutting portion 112.

In the fifth step, the image forming apparatus drags the transmission portion 130 or the powder container cylinder to move in a direction away from the rotational driving force transmitting member 999 (in the same direction as the direction of the powder container cylinder in the third step). Since the support rod 124 cannot be displaced radially inward along the rotational axis of the powder cartridge body, the receiving portion 120 cannot be disengaged from the rotational driving force transmitting member 999, and a gap through which the developer stored in the powder cartridge body can flow out can occur between the receiving portion 120 and the transmission portion 130, as shown in fig. 8. Then, the image forming apparatus can transmit the rotational driving force to the receiving portion 120 through the rotational driving force transmitting member 999, and then to the transmission portion 130 through the transmission rod 125 and the protrusion 132, and finally to the powder cartridge body, so that the developer stored in the powder cartridge body can continuously flow out.

When the powder cartridge is removed from the image forming apparatus, in the state of fig. 8, the image forming apparatus pushes the transmission part 130 or the powder cartridge cylinder to close the gap between the receiving part 120 and the transmission part 130, and the state of fig. 7 is changed; then the movable part 998 moves towards the direction of the powder tube body and drives the movable part 110 to move towards the direction of the powder tube body, and the state is changed into the state shown in fig. 6; then, the rotational driving force transmitting member 999 moves in a direction away from the powder container cylinder, and the state of fig. 5 is changed; then the movable part 998 moves in the direction away from the powder cylinder body, and the movable part 110 moves along with the movable part 998 until the pushing part 112 interferes with the anti-falling groove 126 to prevent the movable part 110 from moving further in the direction away from the powder cylinder; finally, the user can pull out the powder cartridge, and the power receiving part can be restored to the state shown in fig. 4.

Example two

The present embodiment is substantially the same as the power receiving part according to the first embodiment, except that the power receiving part according to the present embodiment further includes a second elastic member 160, and the shape of the receiving portion 120 is modified to accommodate the second elastic member 160.

As shown in fig. 9, the second elastic member 160 is located on the receiving portion 120, and preferably, the second elastic member 160 is located on the receiving teeth 123, but the second elastic member 160 may be disposed at other positions of the receiving portion 120. A recess may be provided on the receiving tooth 123 such that the second elastic member 160 is received in the recess. When the movable portion 110 moves in the direction of the rotational axis of the powder cartridge barrel toward the direction of the powder cartridge barrel, the support rod 124 is biased radially inward with respect to the rotational axis of the powder cartridge barrel by the second elastic member 160. In this embodiment, the second elastic member 160 is a ring-mounted elastic member, and is disposed coaxially with the rotation shaft of the power receiving part. Preferably, the second elastic member 160 is a rubber band.

Compared with the power receiving component in the first embodiment, the power receiving component in the first embodiment has the advantages that the second elastic member 160 restrains the receiving part 120 radially inwards due to the elastic force, so that the interference between the receiving teeth 123 and the image forming device is reduced during the mounting and dismounting of the powder cylinder, and the unsmooth mounting and dismounting processes of the powder cylinder caused by the friction and collision between the receiving teeth 123 and the image forming device are prevented.

Preferably, in order to prevent the aged fracture from falling into the image forming apparatus to damage the quality of the electronic image or damage the image forming apparatus when the second elastic member 160 is a rubber product, the second elastic member may be connected to the receiving teeth 123 or the supporting bar 124. Bonding, thermoforming, interference fit, etc. may be used and will not be described in detail herein.

EXAMPLE III

The present embodiment is substantially the same as the power receiving member of the first embodiment, except that the

movable portions

110a and 110b of the present embodiment are different from the movable portion 110 of the first embodiment.

The process of loading the powder cartridge into the image forming apparatus is described in detail below. The movable member 997 on the image forming apparatus is located outside the rotational driving force transmitting member 999.

In the first step, as shown in fig. 10, when the powder cartridge is not loaded in the image forming apparatus, the urging portion 112a (112b) of the power receiving member is in the escape prevention groove 126, and at this time the support rod 124 cannot be displaced radially inward along the rotational axis of the cylindrical body of the powder cartridge. The receiving portion 120 and the transmission portion 130 are in close contact with each other, so that the developer stored in the powder cartridge body cannot flow out. Preferably, an elastic gasket 140 is further disposed between the receiving portion 120 and the transmission portion 130 to improve sealing performance.

Second, after the powder cartridge is loaded into the image forming apparatus, since the radial distance between the abutting portion 111a (111b) and the rotational axis of the cylindrical body of the powder cartridge is greater than the radial distance between the receiving teeth 123 and the rotational axis of the cylindrical body of the powder cartridge, the movable member 997 on the image forming apparatus pushes the abutting portion 111a (111b), so that the movable portion 110a (110b) moves toward the cylindrical body of the powder cartridge, and the retreat portion 112a (112b) is separated from the escape prevention groove 126, as shown in fig. 11. The support rod 124 may now be biased radially inward along the axis of rotation of the cartridge barrel.

Third, the rotational driving force transmitting member 999 of the image forming apparatus moves in the direction of the cylindrical body of the powder cartridge. Due to the interference between the rotational driving force transmitting member 999 and the driving teeth 123, the support rods are displaced radially inward along the rotational axis of the powder cartridge barrel, and the receiving portion 120 is engaged with the rotational driving force transmitting member 999 as shown in fig. 12.

In the fourth step, the movable member 997 of the image forming apparatus is moved in a direction away from the powder cartridge body. Due to the existence of the first elastic member 150, the movable portion 110a (110b) moves in the direction away from the powder cartridge barrel body following the movable member 997, but unlike the first embodiment, the movable member 997 limits the distance of the movement of the movable portion 110a (110b) in the direction away from the powder cartridge, so that the abutting portion 112a (112b) cannot completely enter the drop-off preventing groove 126. As shown in fig. 13. At this time, the support rod 124 cannot freely shift radially inward along the rotational axis of the powder cartridge cylinder due to the abutting pressing by the abutting portion 112a (112b), but if a proper force is applied, the end of the support rod 124 near the escape prevention groove 126 and the receiving tooth 123 may still shift slightly radially inward along the rotational axis of the powder cartridge cylinder.

In the fifth step, the image forming apparatus drags the transmission portion 130 or the powder container cylinder to move in a direction away from the rotational driving force transmitting member 999 (in the same direction as the direction of the powder container cylinder in the third step). Since the support rod 124 is restricted from radially inwardly shifting along the rotational axis of the powder cartridge barrel, the force required to disengage the receiving portion 120 from the rotational driving force transmitting member 999 is much greater than the frictional force between the receiving portion 120 and the transmission portion 130, and a gap is formed between the receiving portion 120 and the transmission portion 130 through which the developer stored in the powder cartridge barrel can flow out, as shown in fig. 14. Then, the image forming apparatus can transmit the rotational driving force to the receiving portion 120 through the rotational driving force transmitting member 999, and then to the transmission portion 130 through the transmission rod 125 and the protrusion 132, and finally to the powder cartridge body, so that the developer stored in the powder cartridge body can continuously flow out.

The process when the power receiving member is detached from the image forming apparatus is substantially the same as the detachment process in the first embodiment, and will not be described again. The advantage of this embodiment is that in some types of machines, the rotational driving force transmitting member can be displaced a small distance in the direction of the powder cartridge barrel during the process of removing the powder cartridge from the image forming apparatus due to problems such as accuracy, and the powder cartridge can be removed more easily using the embodiment than the first embodiment.

Fig. 15 shows the movable portion 110a, and fig. 16 shows the movable portion 110 b. Both of these movable portions can be used in the aspect of the present embodiment, which is different in that the abutting portion 111b of the movable portion 110b is less likely to be deformed and damaged than the abutting portion of the movable portion 110a, and a reinforcing rib 113b is provided in the vicinity of the urging portion 112 b. The use of these two different movable portions depends mainly on the size of the power receiving part, the amount of developer contained in the powder cartridge, product cost constraints of different qualities, and the like.

Example four

The present embodiment mainly provides another movable portion, the first movable portion 110c1 and the second movable portion 110c2, and the other portions are the same as the power receiving element in the third embodiment.

As shown in fig. 17 and 18, the first movable portion 110c1 and the second movable portion 110c2 according to the present embodiment are shown. The first movable portion 110c1 and the second movable portion 110c2 are independent of each other and each can perform the function of the movable portion 110. When the first movable portion 110c1 and the second movable portion 110c2 are assembled and mounted on the power receiving part, one elastic member is disposed between each of the two movable portions, the first movable portion 110c1 and the second movable portion 110c2, and the receiving portion 120. Due to the action of the elastic member and the restriction of the separation preventing groove 126 of the receiving part 120, the combination of the first movable part 110c1 and the second movable part 110c2 is located on the same plane, and the structure of the combination is similar to that of the movable part 110b (fig. 16) in the third embodiment. The same applies to the structures of the first movable section 110c1 and the second movable section 110c2 when the image forming apparatus is operating normally, which is basically the same as the power receiving member in the third embodiment. This is shown in fig. 17a and 18 a.

However, when the internal components of the image forming apparatus are broken and deformed due to long-time operation, or the internal components of the image forming apparatus interfere with the movable portion due to accuracy problems in the production process of the image forming apparatus, if the movable portion is of an integral structure, the movable portion is restricted from displacement and cannot operate normally, and the powder cartridge cannot be mounted normally, which affects electronic imaging. However, in the present embodiment, if the second movable portion 110c2 is restricted from moving, the first movable portion 110c1 can still normally complete the function of the movable portion, so that the powder cartridge can normally work, as shown in fig. 17b and 18 b; similarly, when the first movable portion 110c1 is restricted from moving, the second movable portion 110c2 can still perform its function normally, so that the powder cartridge can work normally, as shown in fig. 17c and 18 c.

For example, in the fourth step of the third embodiment, when the powder cartridge is mounted on the image forming apparatus, in the process that the movable member 997 of the image forming apparatus moves in the direction away from the cylindrical body of the powder cartridge, if the second movable portion 110c2 is restricted from moving, the first movable portion 110c1 can still normally move in the direction away from the cylindrical body of the powder cartridge, and the movable portion 120 is restricted, so that the movable portion 120 cannot be disengaged from the rotational driving force transmission member 999 of the image forming apparatus, as shown in fig. 19 and 20, and the fifth step can be continued, so that the developer can normally flow out. The states shown in fig. 19 and 20 are the same as the states shown in fig. 17b and 18b, and the states shown in fig. 17c and 18c are similar to these states and are not described again.

It should be noted that, in this embodiment, when the first movable portion 110c1 is pushed to the direction of the powder container barrel to the maximum distance and the first movable portion 110c1 is fixed, the distance that the second movable portion 110c2 can move relative to the first movable portion 110c1 in the direction away from the powder container barrel is greater than or equal to the displacement that the second movable portion 110c2 is pushed by the movable member 997 on the image forming apparatus, so as to ensure that in the state of fig. 17c and 18c, when the displacement of the first movable portion 110c1 is limited, the second movable portion 110c2 can move to the direction away from the powder container barrel by a sufficient distance, thereby preventing the supporting rod 124 on the transmission portion 120 from radially shifting inward with respect to the rotation axis of the powder container barrel.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit the same; although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present application.
