Abstract
Description
Technical Field
[0001] This application relates to the field of mechanical assembly, and in particular to a laser printer photosensitive drum mounting device. Background Technology
[0002] In the manufacturing process of laser printer cartridges, the installation of the photosensitive drum is a crucial assembly step. Existing assembly lines mostly rely on manual methods for gripping, positioning, and locking the photosensitive drum. Operators need to repeatedly handle materials, resulting in high labor intensity and significant efficiency bottlenecks. Furthermore, the precision of the fit between the photosensitive drum shaft and the cartridge bearing hole during manual installation is limited by the operator's skill level, easily leading to misaligned installation and subsequent striped development defects in printing.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
[0027] like Figure 1 and Figure 2 As shown, the embodiment of the laser printer photosensitive drum mounting device includes a frame 100, a transmission unit 200, a processing cartridge loading unit 300, and a photosensitive drum mounting unit 400. The frame 100 serves as the supporting structure for the entire device, used to mount and fix the various functional units. The transmission unit 200 is mounted on the frame 100, and its main function is to progressively transport the printer's processing cartridges along a preset transmission path. Several processing cartridge fixtures 210 are provided along the transmission path on the transmission unit 200. These fixtures are used to fix the processing cartridges, maintaining their stable position during transmission to facilitate precise operation in subsequent processes. The transmission unit 200 can employ a stepper motor-driven conveyor belt structure, achieving progressive transmission through a control system. The processing cartridge loading unit 300 is located at the beginning of the transmission path and is used to load the processing cartridges onto the processing cartridge fixtures 210. The photosensitive drum mounting unit 400 is located behind the processing box loading unit 300 along the transport path, that is, the next station after the processing box has been loaded. The main function of this unit is to mount the photosensitive drum to the corresponding position in the processing box. The photosensitive drum mounting unit 400 may include a photosensitive drum feeding mechanism 420 and a photosensitive drum transfer mechanism 410. The former is responsible for transporting the photosensitive drum to the mounting position, while the latter completes the precise installation of the photosensitive drum.
[0028] With the cooperation of the above components, after the processing box is placed on the fixture by the feeding unit, the transmission unit 200 steps it to the photosensitive drum installation station, and then the photosensitive drum installation unit 400 precisely installs the photosensitive drum into the corresponding position of the processing box, thereby realizing the automated assembly of the printer processing box and the photosensitive drum.
[0029] Understandable, such as Figure 2 and Figure 4As shown, the photosensitive drum mounting unit 400 includes a photosensitive drum transfer mechanism 410 disposed on the side of the transmission unit 200. This transfer mechanism is a key component for transferring the photosensitive drum from the feeding position to the processing box mounting position. Its structure mainly includes a first horizontal moving module 411, a first vertical driving member 412, and a first clamping member 413. The first horizontal moving module 411 is fixedly mounted on the frame 100, parallel to the moving direction of the transmission unit 200, and can adopt a linear motor, belt drive, or slider guide rail structure. The moving end of the first horizontal moving module 411 is connected to the first vertical driving member 412, which is responsible for driving the first vertical driving member 412 to move horizontally along a first path. The first path is a straight track, with one end located at the photosensitive drum mounting position (i.e., the position where the processing box stays on the transmission unit 200 waiting for the photosensitive drum to be installed), and the other end usually connected to the feeding area of the photosensitive drum. The first vertical drive unit 412 is fixed to the moving part of the first horizontal moving module 411 via a connector, and can be a cylinder, a servo motor, a lead screw drive, or a gear and rack mechanism. The drive end of the first vertical drive unit 412 is connected to the first clamping member 413, and its main function is to drive the first clamping member 413 to move upward and downward in the vertical direction, so that the first clamping member 413 can accurately approach the photosensitive drum mounting position of the processing box.
[0030] Understandably, the first clamping member 413 consists of a first bidirectional symmetrical drive assembly and two clamping claws. The fixed end of the first bidirectional symmetrical drive assembly is connected to the drive end of the first vertical drive member 412, forming a vertically movable end effector. The two clamping claws are respectively arranged opposite each other at the two drive ends of the first bidirectional symmetrical drive assembly, forming a symmetrical arrangement. This symmetrical design ensures the balance of clamping force, which is beneficial for the stable gripping of the photosensitive drum. The first bidirectional symmetrical drive assembly can be a pneumatic gripper, an electric gripper, or other mechanism capable of generating symmetrical movement. Its main function is to control the two clamping claws to move synchronously and with equal amplitude toward or away from each other. When it is necessary to clamp the photosensitive drum, the drive assembly causes the two clamping claws to move toward each other until they contact the photosensitive drum and apply an appropriate clamping force; when it is necessary to release the photosensitive drum, it controls the clamping claws to move away from each other, so that the photosensitive drum can remain smoothly in the mounting position of the processing box. The shape and material of the clamping claws are designed according to the specific structural characteristics of the photosensitive drum, and materials with anti-slip and anti-damage surface treatment are usually used to ensure that the surface of the photosensitive drum is not damaged during the clamping process.
[0031] For example, during the entire photosensitive drum transfer process, the first lateral movement module 411 drives the first vertical drive component 412 to move to the photosensitive drum feeding position. The first vertical drive component 412 drives the clamping component to descend to a suitable height. The first bidirectional symmetrical drive assembly controls the clamping claws to close and clamp the photosensitive drum. Then, the first vertical drive component 412 rises, and the first lateral movement module 411 drives the entire assembly to move above the photosensitive drum mounting station. The first vertical drive component 412 descends again to accurately place the photosensitive drum into the predetermined position of the processing box. Finally, the clamping claws release and retract. Understandably, to avoid damage to the surface coating of the photosensitive drum by the clamping claws, the first clamping component 413 can be designed to use clamping claws to grip both end faces of the photosensitive drum.
[0032] Furthermore, to provide a stable material supply to the photosensitive drum transfer mechanism 410, the processing box loading unit 300 is also equipped with a photosensitive drum feeding mechanism 420. For example... Figure 2 and Figure 4 As shown, the photosensitive drum feeding mechanism 420 is located at the material picking end of the photosensitive drum transfer mechanism 410. In this embodiment, the photosensitive drum feeding mechanism 420 adopts the form of a rocker-type stepping material channel. The whole is composed of a guide rail assembly, a support assembly and a rocker assembly. Its movement rhythm is synchronized with the photosensitive drum transfer mechanism 410.
[0033] The guide rail assembly is horizontally arranged along the conveying direction. Its upper surface is provided with several first limiting portions, preferably V-shaped or arc-shaped grooves, slightly larger than the outer diameter of the photosensitive drum, used to position the photosensitive drum radially and axially. The center distance between adjacent first limiting portions is one feeding pitch. Its downstream end corresponds to the material handling position of the photosensitive drum transfer mechanism 410, and its upstream end allows for manual or upstream component replenishment of the photosensitive drum. The support assembly is positioned below and parallel to the guide rail assembly. Its upper surface also has several second limiting portions along its length, with the pitch of these second limiting portions being the same as the pitch of the first limiting portions. The moving end of the rocker assembly is connected to the support assembly, and the driving method can be an eccentric wheel-linkage or servo swing arm structure. Its movement trajectory is a closed loop of "rising - horizontal forward movement - falling - returning," corresponding to a composite motion of "lifting - lateral movement - lowering" generated by the support assembly.
[0034] During the working cycle of the photosensitive drum feeding mechanism 420, the photosensitive drums are first placed sequentially within each of the first limiting parts, with the supporting component at its lowest position and the second limiting part located in the gap between adjacent photosensitive drums. The rocker assembly drives the supporting component to rise, which in turn drives the photosensitive drums to rise. Then, it moves laterally forward one pitch, and the second limiting part pushes and lifts each photosensitive drum, causing it to move forward as a whole and cross into the first limiting part in front. The supporting component descends, and the photosensitive drum falls back into the first limiting part, achieving one step. At this point, one photosensitive drum in the last first limiting part downstream of the track assembly reaches the picking position for the transfer mechanism to grip. The rocker assembly returns to its initial position, completing one feeding cycle, and awaits the start of the next cycle. Through the above structure and action coordination, the photosensitive drum is always subject to the dual constraints of the first and second limiting parts during the feeding process, keeping its axis parallel to the guide rail and preventing rolling and posture deviation. At the same time, the rocker-type mechanism only requires a single-axis drive to achieve step-by-step feeding, with a simple structure and high reliability, meeting the requirements of high-speed cycle while ensuring positioning accuracy.
[0035] Understandably, the photosensitive drum mounting unit 400 also includes a photosensitive drum locking mechanism. This mechanism is designed to ensure that the photosensitive drum is securely fixed in its corresponding position on the processing box after installation, preventing loosening or displacement during subsequent use. The photosensitive drum locking mechanism is located near the photosensitive drum mounting station, typically to the side of the photosensitive drum transfer mechanism 410, maintaining a certain distance from the transmission unit 200 for easy operation and without interfering with the movement of other mechanisms. The photosensitive drum locking mechanism mainly consists of three core components: a locking sensor, a locking drive, and a locking operation component. The locking sensor is installed near the photosensitive drum mounting station and can be a photoelectric sensor, proximity switch, or vision inspection system. Its main function is to detect whether the photosensitive drum is accurately positioned in its corresponding position on the processing box. The locking process only continues when the sensor confirms the photosensitive drum is correctly positioned. This detection mechanism effectively prevents damage to incorrectly installed photosensitive drums during the locking operation. The locking drive can be a combination of actuators such as cylinders, electric push rods, or servo motors. The locking drive is fixedly mounted on the frame 100, and its placement ensures precise proximity to the locking structure of the photosensitive drum on the processing cartridge. The drive end of the locking drive is connected to the locking operating component. Through precisely controlled linear or rotary motion, the locking operating component is moved to the corresponding position on the processing cartridge to perform the locking operation. The locking operating component is the working part that directly contacts the processing cartridge and the photosensitive drum; its structural design must match the locking mechanism on the processing cartridge. Depending on the specific structure of the printer's processing cartridge, the locking operating component may be a screwdriver, a pressure block with a specific shape, etc.
[0036] After the photosensitive drum transfer mechanism 410 completes the installation of the photosensitive drum, the locking sensor detects the position of the photosensitive drum. If the detection result shows that the photosensitive drum is correctly positioned, the locking drive is activated, moving the locking operating component to the locking position of the photosensitive drum on the processing box. The locking operating component performs specific locking actions (such as rotation, pressing, or pushing the latch) to ensure a tight fit between the locking structure on the processing box and the photosensitive drum. After locking is completed, the locking drive returns the locking operating component to its initial position, awaiting the next work cycle. It is worth noting that, in addition to detecting the position of the photosensitive drum, the locking sensor can also monitor the completion status of the locking operation through torque feedback or displacement detection, ensuring that each locking operation achieves the expected effect. Furthermore, the control system of the locking mechanism usually has a fault detection function, which can promptly alarm and stop the machine when the locking operation is abnormal, preventing damage to equipment or products due to improper locking. The use of the photosensitive drum locking mechanism not only ensures the stability of the photosensitive drum in the processing cartridge, but also improves the automation and reliability of the entire assembly process, providing quality assurance for the subsequent use of the laser printer.
[0037] In some embodiments, the laser printer drum mounting device includes, in addition to the frame 100, transmission unit 200, processing cartridge loading unit 300, and drum mounting unit 400, a toner blade mounting unit 500. The toner blade is a crucial component in the processing cartridge that works in conjunction with the drum; its main function is to control and evenly scrape the toner from the drum surface to ensure print quality. Figure 1 and Figure 2 As shown, the powder discharge knife mounting unit 500 is located on the rear side of the processing box feeding unit 300 along the transmission path. It can be arranged sequentially or in parallel with the photosensitive drum mounting unit 400. Its main function is to install the powder discharge knife to the corresponding position in the processing box.
[0038] The powder dispensing blade mounting unit 500 can adopt a similar overall structural design to the photosensitive drum mounting unit 400, including three main functional modules: a powder dispensing blade transfer mechanism 510, a powder dispensing blade feeding mechanism 520, and a powder dispensing blade locking mechanism. These three modules cooperate to complete the entire process of automatic feeding, precise movement and installation, and secure locking of the powder dispensing blade. Specific implementation methods can be found above and will not be repeated here.
[0039] Understandably, the processing cartridge loading unit 300 is the first working unit of the laser printer's photosensitive drum mounting equipment. Its main function is to orderly introduce the processing cartridges to be processed into the production line and accurately place them onto the processing cartridge fixture 210 of the transfer unit 200. For example... Figure 3As shown, this unit includes two key collaborative mechanisms: a processing box loading mechanism 310 and a processing box feeding mechanism 320. The processing box loading mechanism 310 is the actuator for precise positioning and handling of the processing boxes. Its construction typically employs a three-axis robotic arm driven by a servo motor, controlling movement in the X, Y, and Z directions respectively. The end effector of the loading mechanism is equipped with a dedicated gripper, which can be designed with corresponding gripping points according to the structural characteristics of the processing box. It typically uses a combination of pneumatic vacuum suction cups or mechanical grippers to ensure a stable grip on the processing box without damaging its surface. The robotic arm's motion trajectory is optimized to complete the precise placement action from the feeding area to the fixture using the shortest path, and the positioning status of the processing box is detected by photoelectric or vision sensors. The processing box feeding mechanism 320 is responsible for providing a continuous and stable material supply to the loading mechanism. This mechanism can adopt a multi-layer belt-type buffer conveyor structure, with the inlet end connecting to a manual loading station or the automatic output of an upstream process, and the outlet end connecting to the material picking area of the loading mechanism. The feeding mechanism is equipped with multiple sets of sensors to detect the arrival status of the processing boxes, the number of boxes in the queue, and potential jamming situations. This information is fed back to the control system to synchronize the feeding and loading cycles. To prevent positional shifts in the processing boxes during transport, adjustable limit guides are installed on both sides of the feeding line to accommodate variations in the size of different processing box models.
[0040] Understandably, to ensure the quality and reliability of the photosensitive drum installation, the laser printer photosensitive drum installation equipment in this embodiment is equipped with a detection unit at the end of the transmission path. This unit, as a quality monitoring link for the entire assembly line, can comprehensively inspect the processing box after the photosensitive drum installation is completed, promptly identifying and reporting any potential assembly defects. The detection unit includes several image detection modules, which are arranged around the key parts of the processing box to form a multi-angle, all-around detection network. Each image detection module typically consists of a high-resolution industrial camera, a dedicated lighting system, and image processing software. For example, the image detection modules mainly detect the following key aspects:
[0041] Check the position of the photosensitive drum to ensure it is fully seated in the mounting groove of the processing box;
[0042] The axial alignment of the photosensitive drum ensures that both ends are coaxial with the support structure of the processing box;
[0043] Check the locking status of the photosensitive drum locking mechanism to verify whether the latches or screws are properly secured;
[0044] Check for scratches, stains, or other visible damage on the surface of the photosensitive drum;
[0045] The overall assembly relationship between the processing box and the photosensitive drum was checked to ensure there was no interference or abnormal gaps.
[0046] The detection unit adopts a master-slave control architecture. Each image detection module transmits the acquired image data to the central processing unit in real time, where a dedicated algorithm performs comprehensive analysis and judgment. When any non-compliance is detected, the system immediately issues an alarm and records detailed information. Simultaneously, it can trigger the transmission unit 200 to pause operation or automatically divert defective products to the rework area. Furthermore, the detection unit also has data statistics and analysis functions, generating real-time quality reports to provide decision-making support for production management.
[0047] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
