[0016] Figure 1 This is a top view of the automatic assembly equipment for the powder discharging knife involved in the utility model; Figure 2 This is a three-dimensional diagram of the automatic assembly equipment for the powder discharging knife involved in the utility model; Figure 3 It is a three-dimensional diagram of a powder discharge knife feeding device in the automatic powder discharge knife assembly equipment involved in the utility model.

[0017] The processing box includes at least a developing shell that can accommodate the developer and a developing member rotatably arranged in the developing shell. The developing member can be used to carry the developer and supply the developer to the external photosensitive member. The processing box is also provided with a powder discharge knife that contacts the developing member. The powder discharge knife is used to evenly distribute the developer on the surface of the developing member.

[0018] The present application relates to an automatic assembly device for a powder discharge knife. Hereinafter, a processing box without a powder discharge knife installed is referred to as a "part to be assembled". The automatic assembly device for a powder discharge knife is used to install the powder discharge knife to the part to be assembled. The powder discharge knife involved in the present application can be a flexible part or a rigid metal part. When the powder discharge knife is a flexible part, the powder discharge knife is preferably a sheet-like structure.

[0019] like Figure 1-Figure 3 As shown, the automatic assembly equipment 1 for the powder discharge knife has an up-down direction / height direction / vertical direction, a front-back direction / length direction / longitudinal direction and a left-right direction / width direction / transverse direction. The automatic assembly equipment 1 for the powder discharge knife includes a machine 11, a conveying device 12 for parts to be assembled, a powder discharge knife loading device 13 and a powder discharge knife installation device 14; the conveying device 12 for parts to be assembled is arranged on the machine 11, for loading the parts to be assembled 100 and conveying / delivering the parts to be assembled 100 along the conveying direction. In this embodiment, the conveying direction is from back to front; the powder discharge knife loading device 13 is arranged on the conveying device 11 for parts to be assembled 2, the powder knife loading device 13 is used to load the stacked powder knives 41 and transport the powder knife 41 along the loading direction. Along the front-to-back direction, the loading direction intersects with the conveying direction; the powder knife installation device 14 is arranged on the machine table 11, and is used to take out the powder knife 41 and install it to the part to be assembled 100. The powder knife installation device 14 can move between the assembly station and the loading station. At the loading station, the powder knife installation device 14 can grab the powder knife 41. At the assembly station, the powder knife installation device 14 can install the grabbed powder knife 41 to the part to be assembled 100.

[0020] Specifically, the powder knife feeding device 13 and the powder knife installation device 14 are arranged in the left and right directions. Further, the powder knife installation device 14 includes a bracket 141, a moving part 142 installed on the bracket 141 and a material taking part 143 installed on the moving part 142. Specifically, Figure 2 As shown, the moving component 142 is used to drive the picking component 143 to move between the assembly station and the loading station, that is, the picking component 143 can move between the assembly station and the loading station along with the moving component 142, so that after the picking component 143 grabs the powder knife 41, the powder knife 41 can be installed on the to-be-assembled part 100. The picking component 143 is provided with a picking portion (such as a suction cup), and the picking portion can grab the powder knife 41 as the picking component 143 extends relative to the moving component 142, and after returning to the assembly station with the grabbed powder knife 41, the powder knife 41 can be installed on the to-be-assembled part 100. Among them, the moving component 142 can be a device such as a servo electric cylinder, a manipulator, etc. that can drive the picking component 143 to move, and the picking component 143 can be a device such as an electric push rod, a pneumatic push rod, etc. that can perform telescopic movement.

[0021] Furthermore, the powder knife loading device 13 includes a base 131, a conveyor belt 132 arranged on the base 131, a partition 133 arranged on the conveyor belt 132 and a powder knife loading motor 134. Specifically, the powder knife 41 is stacked and placed on the conveyor belt 132; the conveyor belt 132 can rotate to transport / transmit the powder knife 41 to the loading station along the loading direction, and the conveyor belt 132 is tilted relative to the vertical direction (up and down direction), and its tilt direction is that along the conveying direction, the upper end of the conveyor belt 132 is located on the downstream side of the lower end, that is, in this embodiment, along the direction from back to front, the upper end of the conveyor belt 132 is located in front of the lower end to prevent the powder knife 41 from being transported / transmitted during the transportation / transmission process. When tilted, the powder knife 41 can be stacked more stably, and the tilting direction is parallel to the loading direction; at least one partition 133 is provided on the conveyor belt 132, and the partition 133 is used to support the powder knife 41 stacked on the conveyor belt 132. In this embodiment, a plurality of partitions 133 are provided on the conveyor belt 132, and the plurality of partitions 133 are arranged at intervals on the conveyor belt 132. From top to bottom, the plurality of partitions 133 are successively the first partition 133, the second partition 133...the Nth partition 133; the powder knife loading motor 134 is used to control the rotation and movement of the conveyor belt 132. When the conveyor belt 132 rotates, the powder knife 41 is driven to be transported / transmitted along the loading direction.

[0022] Next, the process of the picking component 143 grabbing the powder knife 41 will be described in detail. Specifically, along the left-right direction, the picking component 143 first moves along with the moving component 142 from the assembly station to the loading station. Then, the picking component 143 extends relative to the moving component 142 in a direction opposite to the loading direction and squeezes the powder knife 41. The picking component then grabs the powder knife 41. Alternatively, the powder knife 41 is squeezed and grabbed by the picking component. Then, the picking component 143 retracts along the loading direction with the grabbed powder knife 41 and moves along with the moving component 142 along the left-right direction and returns to the assembly station. Finally, the powder knife 41 is installed on the component to be assembled 100.

[0023] Furthermore, when the material picking component 143 squeezes the powder knives 41, the stacked powder knives 41 and the partitions 133 will be subjected to downward pressure. Since multiple partitions 133 are provided on the conveyor belt 132, the powder knives 41 are supported separately by multiple partitions 133, and each partition 133 supports a set number of powder knives 41. In this way, it can be avoided that the powder knives 41 are squeezed and tilted by the material picking component 143 due to too many powder knives 41. It is also convenient for the material picking component 143 / material picking part to grab the powder knives 41. Moreover, providing multiple partitions 133 can prevent a single partition 133 from being damaged due to excessive pressure.

[0024] In one embodiment, the picking component 143 is configured to extend a different / variable distance in a direction parallel to the loading direction when grabbing the powder knife 41, that is, on the first partition 133, the picking component 143 keeps the conveyor belt 132 stationary from grabbing the first powder knife 41 to grabbing the last powder knife 41. Therefore, the powder knife loading motor 134 is configured to control the conveyor belt 132 to move at a long time interval and a long distance. Specifically, along the inclined direction of the conveyor belt 132, on the first partition 133, after the picking component 143 grabs the last powder knife 41 on the bottom layer, the powder knife loading motor 134 controls the conveyor belt 132 to move a first distance S1 along the loading direction, so that the second partition 133 moves to the position where the first partition 133 is located, and the conveyor belt 132 stops moving, that is, the first distance S1 is the distance between two adjacent partitions 133, and the picking component 143 returns to the assembly station after grabbing the powder knife 41 at the loading station. Position and install the powder knife 41 to the part to be assembled 100, and then move from the assembly station to the loading station to continue grabbing the first powder knife 41 on the top layer of the second partition 133. After a first time interval T1, the powder knife loading motor 134 controls the conveyor belt 132 to move a first distance S1 along the loading direction. The first time interval T1 means that on a single partition 133, the material-taking component 143 starts from grabbing the first powder knife 41 on the top layer and ends with grabbing the last powder knife 41 on the bottom layer.

[0025] In one embodiment, the picking component 143 is configured to extend the same / unchanged distance in a direction parallel to the feeding direction when grabbing the powder knife 41. In order to enable the powder knife 41 stacked below to be grabbed by the picking component 143, the powder knife loading motor 134 is configured to control the conveyor belt 132 to move at short time intervals and short distances. Specifically, along the inclined direction of the conveyor belt 132, on a single partition 133, after the picking component 143 grabs the first powder knife 41 on the top layer, the powder knife loading motor 134 controls the conveyor belt 132 to move a second distance S2 along the feeding direction, so that the second powder knife 41 is transported to the position where it is grabbed by the picking component 143 (the position where the first powder knife 41 is located), and the conveyor belt 132 stops moving, that is, the second distance S2 is the distance between two adjacent powder knives 41, or in other words, the second distance S2 is the thickness of a single powder knife 41; the picking component 143 After grabbing the powder knife 41 at the loading station, 43 returns to the assembly station and installs the first powder knife 41 to the part to be assembled 100, and then moves from the assembly station to the loading station to continue grabbing the second powder knife 41. After a second time interval T2, the powder knife loading motor 134 controls the conveyor belt 132 to move a second distance S2 along the loading direction. The second time interval T2 means that the material-taking component 143 starts from grabbing the first powder knife 41 and ends with grabbing the second powder knife 41. The first powder knife 41 and the second powder knife 41 are arranged adjacent to each other.

[0026] Furthermore, the first time interval T1 is greater than the second time interval T2, and the first distance S1 is greater than the second distance S2.

[0027] The utility model provides an inclined conveyor belt and multiple partitions, so that the powder knives can remain stable when they are stacked and installed, thereby preventing the powder knives from tipping over, and can improve the installation efficiency of the automatic assembly equipment for powder knives. At the same time, the powder knives are uniformly installed through the automatic assembly equipment for powder knives, and the assembly process is unified. Therefore, the development quality can also be guaranteed, and the automatic assembly equipment for powder knives has high production efficiency, which can greatly reduce labor costs.
