Description

Technical Field

[0001] This utility model relates to the field of clutch manufacturing technology, specifically to an automatic stacking device for clutch discs. Background Technology

[0002] As a core component of automotive transmission systems, clutch plate assemblies are typically composed of alternating stacks of friction plates and steel plates. In traditional manufacturing processes, this stacking is primarily manual, with the following procedure: workers retrieve friction plates or steel plates one by one from a hopper, manually adjust their angular positions, and then stack them sequentially onto a tooling table. However, with the automotive industry's increasing demands for production efficiency and component precision, traditional manual stacking has revealed significant drawbacks. For example, manual grasping, angular adjustment, and stacking are time-consuming; the stacking time for a single plate assembly, such as 7 friction plates + 6 steel plates, far exceeds the requirements of automated equipment. The large errors in manual visual angular adjustment lead to decreased transmission performance after assembly. Operator fatigue or distraction can easily cause problems such as missing plates, incorrect plate counts, or reversed plate order, requiring additional quality control and rework, increasing costs. On high-speed production lines, close-range manual operation of mechanical tooling poses safety hazards such as pinching and collisions. In recent years, the rapid development of industrial automation technology has provided new solutions for clutch plate stacking processes. For instance, the application of technologies such as robotic arm collaborative operation and machine vision inspection can significantly improve production efficiency and precision. However, existing automated equipment still has limitations. For example, a single robotic arm cannot complete the alternating stacking of multiple plates within 54 seconds. It lacks a real-time detection and servo compensation system. The angular consistency after stacking still relies on manual re-inspection. An unreasonable hopper design can easily lead to plate jamming or overlap, affecting continuous production. Based on this, there is an urgent need to develop a highly efficient and high-precision fully automatic clutch plate stacking device. Through the alternating operation of dual robotic arms, intelligent angular detection and compensation, and a modular feeding system, it can break through the technical bottlenecks of traditional processes and meet the stringent requirements of the automotive industry for production efficiency, precision, and safety.

A friction plate angular detection camera 13 is provided above the friction plate horizontal pushing device 11, and a steel plate angular detection camera 14 is provided above the steel plate horizontal pushing device 12. The friction plate hopper 2 is equipped with a friction plate hopper turntable 201 rotatably connected to the base 1.

[0030] Both the friction plate lifting device 4 and the steel plate lifting device 5 include: a lifting cylinder and a lifting lever.

[0031] When using this invention, firstly, multiple friction plate storage racks 202 are evenly distributed circumferentially on the friction plate storage turntable 201 inside the friction plate storage bin 2. The friction plate storage turntable 201 rotates, aligning one of the friction plate storage racks 202 with the friction plate lifting device 4. The lifting cylinder of the friction plate lifting device 4 drives the lifting paddle to vertically lift the friction plate to a preset height. The steel plate storage turntable 301 of the steel plate storage bin 3 rotates synchronously, aligning the steel plate storage rack 302 with the steel plate lifting device 5. The steel plate lifting device 5 vertically lifts the steel plate to the target height using its lifting cylinder. The horizontal pushing cylinder of the friction plate horizontal pushing device 11 drives the pushing plate to horizontally push the lifted friction plate to the robotic arm gripping position. The steel plate horizontal pushing device 12 operates synchronously, pushing the steel plate... The friction sheet and steel sheet are sent to the corresponding gripping position. The friction sheet angular detection camera 13 and the steel sheet angular detection camera 14 respectively perform angular detection on the friction sheet and steel sheet after feeding, and record the current angular deviation. The lateral movement cylinder 802 of the robot arm lateral movement device 8 drives the lateral movement connecting plate 804 to slide along the lateral movement guide rail 803, so that the friction sheet robot arm 9 moves to the friction sheet gripping position. The friction sheet lifting cylinder 903 of the friction sheet robot arm 9 drives the friction sheet lifting connecting plate 902 to descend along the friction sheet lifting slide rail 901. The friction sheet gripper 9044 clamps the friction sheet through the friction sheet gripping cylinder 9041 and then rises. According to the angular detection result, the friction sheet rotary motor 9042 drives the friction sheet gripper 9044 to rotate to compensate for the angular deviation and ensure that the sheet angle is consistent. The friction sheet robot arm 9 carries the adjustment The adjusted friction plate is moved laterally to the first position of the two-position rotary table 6. Simultaneously, the friction plate robot 9 moves above the rotary table 6, and the steel sheet robot 10 moves to the steel sheet gripping position. The friction plate lifting cylinder 903 and the steel sheet lifting cylinder 1003 descend synchronously, and the friction plate gripper 9044 releases, precisely placing the friction plate at the workstation. The steel sheet gripper 10044 clamps the steel sheet via the steel sheet gripping cylinder 10041. Then, the friction plate lifting cylinder 903 and the steel sheet lifting cylinder 1003 rise synchronously. The steel sheet rotary motor 10042 drives the steel sheet gripper 10044 to rotate based on the angular detection results, compensating for angular deviations and ensuring consistent sheet angles. The friction plate robot 9 and the steel sheet robot 10 move synchronously, and the friction plate robot 9 moves back to the friction plate gripping position. The steel sheet robot arm 10 moves to the first station of the two-position turntable 6, and then places the steel sheet on top of the friction plate at the same station, completing the alternating stacking. This action is repeated until the first station has completed the alternating stacking of 7 friction plates and 6 steel sheets. When a set of sheets is stacked, the rotary motor of the two-position turntable 6 drives the rotating shaft, causing the worktable to rotate 180°, rotating the finished sheet set to the unloading position. At the same time, the vacated second station returns to the stacking start position, and the next set of sheets immediately begins stacking at the second station, realizing continuous production. The control system, such as a PLC, coordinates the timing of the actions of each component: the actions of the lifting device and the pushing device are synchronized to ensure continuous material supply; the robot arm's lateral movement, gripping, and rotation are strictly matched with the turntable rotation to ensure that 13 sheets are stacked within 54 seconds.Angular detection data is fed back to the rotary motor in real time to ensure angular consistency.
