Description

Technical Field

[0001] The utility model relates to the technical field of automated assembly equipment, in particular to an end cover gear set assembly machine. Background Art

[0002] The toner cartridge for printers and copiers has a gear set installed on its side end cover, which is used to receive the driving force for driving the toner supply and development structure of the toner cartridge, such as the photosensitive drum, the developing roller, and the stirring frame, so the gear set is rotatably supported on the end cover 11. The gear set on the end cover 11 includes a first transmission gear 12 and a second transmission gear 13, and the first transmission gear 12 and the second transmission gear 13 are rotatably supported on the end cover 11 in meshing relationship with each other. Figure 1 shown.

[0003] In order to correctly mesh the first transmission gear 12 and the second transmission gear 13 assembled on the end cover 11, an existing assembly machine adjusts the transmission gear assembly assembled on the end cover 11 to be in a correct meshing state through an auxiliary meshing module. However, the auxiliary meshing module of the existing assembly machine includes a clamping mechanism, a meshing mechanism, a flat plate and a pressure plate. The clamping mechanism includes a frame, a clamping cylinder, a guide rod, a limit rod and a limiter. The frame is mounted on the conveyor frame, and the flat plate is fixed on the frame. There are two guide rods, which are symmetrically arranged on the flat plate. The clamping cylinder is arranged on the flat plate and is located between the symmetrically arranged guide rods. The limit rod is arranged under the guide rod. The limiter is arranged at the upper end of the guide rod. A pressure plate is provided at the output end of the clamping cylinder. The meshing mechanism includes a drive motor, a motor gear, a transition gear A, a transition gear B and a drive gear. The drive motor is arranged on the pressure plate. On the top, the motor gear is arranged on the driving motor, the transition gear A, the transition gear B and the driving gear are arranged on the side end of the pressure plate, the motor gear is meshed with the transition gear A, the transition gear A is meshed with the transition gear B, and the transition gear B is meshed with the driving gear. It can be seen that the structure of the existing auxiliary meshing module is too complicated, and the number of components is large, which greatly increases the production cost. At the same time, function transmission between too many components will reduce the working accuracy, thereby affecting the working stability and reliability, and function transmission between too many components will prolong the working rhythm response time, thereby reducing the production assembly efficiency.

The adjustment control mechanism is arranged on the lifting seat and can control the adjustment pressure head to rotate around the vertical direction. The adjustment pressure head can be pressed against the second transmission gear.

[0006] It can be seen from the above scheme that the drive mechanism of the end cover gear assembly machine of the utility model controls the workbench to rotate in the vertical direction, and transfers the jig with the end cover placed thereon to the first assembly mechanism. Then, the first control mechanism of the first assembly mechanism controls the first movable seat to move in the horizontal and vertical directions, and the first clamping mechanism controls the two first clamps to move toward each other, so that the two first clamps clamp the first transmission gear to be assembled on the end cover.
