Description

Technical Field

[0001] The utility model belongs to the technical field of photosensitive drum assembly, in particular to a universal joint gear positioning mechanism for a photosensitive drum of a toner drum automatic line. Background Art

[0002] A universal joint gear is provided at the end of the photosensitive drum. The universal joint gear is provided with a universal joint that can rotate in multiple directions. Specifically, when assembling the photosensitive drum, the universal joint gear needs to be fastened to the end of the photosensitive drum to prevent it from falling off. The existing practice is to manually put the universal joint gear on the end of the photosensitive drum and press it to fasten the universal joint gear to the end of the photosensitive drum. This requires workers to press repeatedly and apply a large force, resulting in high labor intensity for the workers. In addition, the manual pressing force is not uniform. When the applied pressure is small, the universal joint gear may become loose, affecting the quality of assembly. In addition, the efficiency of manual assembly is low and cannot meet the needs of mass production. Utility Model Content

[0005] (II) Technical solution

[0006] To achieve the above objectives, the technical solutions provided by this application are as follows:

[0007] A photosensitive drum universal joint gear positioning mechanism for a toner drum automatic production line, comprising: a movable first adjustment component, which can extend when a photosensitive drum with a universal joint gear pre-installed at the end moves to its corresponding position, driving universal joints mounted on the universal joint gear facing both sides and downward to swing to a horizontal state that coincides with the center of the universal joint gear; a second adjustment component movably arranged above the first adjustment component, which can move downward when the first adjustment component moves below the universal joint, driving the universal joint facing upward to swing downward to a horizontal state that coincides with the center of the universal joint gear on the first adjustment component; and further comprising: a power shaft, which can be movably arranged, and can press the universal joint and the universal joint gear when the universal joint is adjusted to a horizontal state, so that the universal joint gear and the end of the photosensitive drum are fastened to each other;

[0008] The present application sets the first and second adjustment components and the power shaft. In the previous processing step, the universal joint gear is pre-mounted on the end of the photosensitive drum but not pressed. When the photosensitive drum is transmitted to the positions of the first and second adjustment components and the power shaft, the first and second adjustment components and the power shaft cooperate with each other. The first and second adjustment components first adjust the angle of the universal joint to adjust the universal joint to a horizontal state that coincides with the center of the universal joint gear. Then the power shaft abuts against the universal joint to apply pressure to the universal joint to press the universal joint gear into the end of the photosensitive drum, so that the universal joint gear is tightly combined with the end of the photosensitive drum. In this way, there is no need for workers to press and assemble the universal joint gears one by one, thereby reducing labor intensity. In addition, due to the mechanized operation, the pressure applied to the universal joint gear can be unified to ensure that the universal joint gear can be stably fixed to the end of the photosensitive drum, thereby improving the efficiency of assembly.

[0009] In some embodiments, the first adjustment assembly includes: a first vertical drive device arranged vertically, a first transverse drive device arranged transversely on the first vertical drive device, and a limiter arranged on the first transverse drive device, wherein the power shaft is arranged on the first transverse drive device.

[0011] The limiting member is configured to include a limiting portion with a V-shaped structure and a long connecting portion, and the length of the connecting portion is configured to be longer than the power shaft. In this way, when the power shaft and the first adjusting component approach the direction of the universal joint synchronously, the first adjusting component can first adjust the direction of the universal joint through the limiting portion with the V-shaped structure, and when the power shaft moves to a position abutting the universal joint, the universal joint gear can be pressed against the photosensitive drum.

[0012] In some embodiments, the second adjustment assembly includes: a second lateral drive device, a second vertical drive device disposed on the second lateral drive device, and an auxiliary pressure plate disposed on the second vertical drive device to drive the universal joint to swing downward;

[0013] In some embodiments, it further comprises: a fixed seat provided with a guide rail on the first transverse driving device, a sliding seat provided on the fixed seat and slidably matched with the guide rail, wherein the limiter and the power shaft are both provided on the sliding seat, and further comprises: a buffer provided between the sliding seat and the fixed seat, wherein one end of the buffer is connected to the sliding seat, and the other end is connected to the fixed seat;

[0014] By providing a buffer, the impact force of the power shaft can be buffered, thereby preventing the power shaft from hard collision with the universal joint and the universal joint gear, which may cause easy damage to the universal joint and the universal joint gear.

It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0022] See also Figure 1-Figure 4 The utility model provides a toner cartridge automatic line photosensitive drum universal joint gear positioning mechanism, comprising: a movable first adjusting component, which can extend when a photosensitive drum 11 with a universal joint gear 12 pre-installed at the end moves to its corresponding position, driving universal joints 13 installed on the universal joint gear 12 to swing to a horizontal state that coincides with the center of the universal joint gear 12, and a second adjusting component movably arranged above the first adjusting component, which can move downward when the first adjusting component moves below the universal joint 13, driving the universal joint 13 facing upward to swing downward to a horizontal state on the first adjusting component that coincides with the center of the universal joint gear 12, and also includes: a power shaft 2, which can be movably arranged, and can squeeze the universal joint 13 and the universal joint gear 12 when the universal joint 13 is adjusted to a horizontal state, so that the universal joint gear 12 and the end of the photosensitive drum 11 are fastened to each other.

[0023] Specifically, the first adjustment assembly includes: a first vertical drive device 6 arranged vertically, a first horizontal drive device 7 arranged horizontally on the first vertical drive device 6, and a stopper 1 arranged on the first horizontal drive device 7, wherein the power shaft 2 is arranged on the first horizontal drive device 7. The first vertical drive device 6 and the first horizontal drive device 7 can be cylinders, and the first vertical drive device 6 and the first horizontal drive device 7 can drive the stopper 1 to move toward the center direction of the universal joint gear 12 to adjust the direction of the universal joint 13. Specifically, multiple first horizontal drive devices 7 can be arranged at the same time, and the multiple first horizontal drive devices 7 are driven and connected to each other, so that the moving stroke of the first horizontal drive device 7 can be extended.

[0024] Specifically, the limiter 1 includes: a connecting portion and a limiting portion. The connecting portion is a long strip structure connected to the first transverse drive device 7. The limiting portion is arranged at the end of the connecting portion and is a vertical V-shaped structure for engaging with both sides and the bottom surface of the universal joint 13. Specifically, the length of the connecting portion is longer than the power shaft 2.

[0025] Specifically, the second adjustment assembly includes: a second transverse driving device 8, a second vertical driving device 9 arranged on the second transverse driving device 8, and an auxiliary pressure plate 10 arranged on the second vertical driving device 9 to drive the universal joint 13 to swing downward.

[0026] Specifically, the assembly process is as follows:

[0027] In the previous step, the staff put the universal joint gear 12 on one end of the photosensitive drum 11 but did not press it, and then placed the photosensitive drum 11 with the universal joint gear 12 on the transmission line for downward flow. Since the universal joint 13 on the universal joint gear 12 will face different directions, when the transmission line flows to the position of the positioning mechanism, it stops, and the lower limit member 1 and the power shaft 2 are driven by the first vertical drive device 6 and the first horizontal drive device 7 to move forward synchronously. Since the length of the limit member 1 is longer than the power shaft 2, the limit part can drive the universal joint 13 facing left, right, and downward to swing to the horizontal direction during the movement. At the same time, While the power shaft 2 has not yet reached the contact with the universal joint 13, the auxiliary pressure plate 10 on the second adjustment assembly moves downward under the drive of the second vertical drive device 9 and the second horizontal drive device 8, driving the upward universal joint 13 to swing downward and adjust to the horizontal direction. When the power shaft 2 reaches the position of contact with the universal joint 13, the universal joint 13 has been adjusted to a horizontal state that coincides with the center of the universal joint gear 12. Driven by the first horizontal drive device, the power shaft 2 continues to move forward to apply pressure to the universal joint 13, so that the universal joint gear 12 is pressed into the end of the photosensitive drum 11, so that the universal joint gear 12 is tightly combined with the end of the photosensitive drum 11. Specifically, a jig can be placed on the transmission line to fix the position of the photosensitive drum 11 to prevent the position of the photosensitive drum 11 from shifting when the positioning mechanism presses the universal joint gear 12. The transmission line will stop intermittently during circulation to facilitate the positioning mechanism to perform processing operations.
