Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of support pad equipment, and in particular to a support pad equipment for pressing the gear components of a car rear wiper motor. Background Technology
[0002] As a core component of the vehicle's electronic control system, the rear wiper motor is essentially a small DC permanent magnet motor. It receives command signals from the vehicle control module or wiper switch, efficiently converting electrical energy into rotational mechanical energy to drive the rear window wiper blades to reciprocate and clear obstructions. With the widespread adoption of SUVs and MPVs, it has become a standard feature ensuring driving safety and convenience in inclement weather. The automotive industry's stringent quality management systems, with their strict standards for component assembly precision and consistency, further highlight the necessity of upgrading the assembly process for the motor's gear components. Traditional gear component support pad pressing and lubrication processes rely on purely manual operation, which presents significant drawbacks. The system suffers from two major shortcomings: quality and efficiency. On the quality front, manual pressing lacks precise force control and positioning methods, which can easily lead to problems such as missing or broken support pads. Manual lubrication, on the other hand, cannot achieve directional and quantitative control, resulting in uneven lubrication, positional deviations, and imbalances in lubrication volume. These defects directly cause performance issues such as abnormal noise from the wiper motor, lubrication failure, and accelerated gear wear. On the efficiency front, the serial operation mode of manual operation lacks parallel design, and the accuracy of the movements depends on the skill of the operator. The processing time for a single piece is long, making it difficult to adapt to the high-volume, high-speed production needs of the automotive industry. This restricts the release of production capacity and increases the product defect rate and after-sales maintenance costs. Utility Model Content

The end of the discharge track of the vibratory feeder 47 is aligned with the initial position of the push rod 55 for continuously conveying the support pad to the lifting area.
[0017] Working Principle: Using this invention, the timing linkage of the platform and pressing mechanism 1, oiling mechanism 2, rotary guide mechanism 3, and automatic feeding mechanism 4, combined with multi-sensor closed-loop control and flexible force control technology, enables the automated and high-precision completion of the pressing and oiling process of the gear component support pad. The automatic feeding mechanism 4 serves as the core unit for supplying the support pad. The vibratory feeder 47 uses high-frequency vibration to transport the bulk support pads in a uniform orientation to the top material area. The second photoelectric sensor 48, installed on the mounting sheet metal 49, monitors the position of the support pad in real time. When the support pad is detected to have reached the preset position, the third cylinder 50 is triggered. The third cylinder 50 drives the top material rod 55 to push the support pad to the picking position along the guide trajectory. The limit block 53 and the adjusting pull plate... 54. The adjustable mounting plate 51 and mounting base 52 work together to ensure consistent top material position. The top material stroke can be flexibly adjusted according to the support pad specifications to ensure compatibility with different workpiece models and provide a stable material supply foundation for subsequent material handling processes. The rotary guide mechanism 3 achieves parallel connection between material handling and pressing processes through multi-station cycles. The rotary actuator 35, installed on the heat dissipation mounting component 36, drives the turntable 40 to rotate intermittently at a preset angle. The slotted switch 34 and the sensing element 33 on the switch mounting block 32 constitute an external zero-origin detection unit to calibrate the rotation angle of the turntable 40 in real time, ensuring the alignment accuracy of the pressing head 44 with the pressing station when the equipment restarts or operates continuously. When the pressing head 44 on the turntable 40 rotates to the material handling station, it is fixed to the second cylinder mounting plate 14. The second cylinder 13 is guided downward along the double-shoulder linear bearing 41. The pressing head 44 is fixedly connected to the guide shaft 42 by the external hexagonal nut 45. Its internal cavity precisely fits the contour of the support pad. The ball-head elastic plunger 46 securely locks the support pad inside the cavity through elastic preload. The polyurethane washer 43 buffers the contact stress between the pressing head 44 and the guide shaft 42 to prevent displacement or detachment during material handling. After material handling is completed, the second cylinder 13 drives the pressing head 44 to move upward and return to its original position under the elastic restoring force of the compression spring 38. The first metal washer 37 and the second metal washer 39 disperse the force of the compression spring 38. The turntable 40 continues to rotate to transport the pressing head 44 carrying the support pad to the pressing station. The frame and pressing mechanism 1 serve as the core execution unit, driven by the first... A first support column 16 and a second support column 18 support the upper plate 17 and the equipment mounting plate 19, while the lower plate 20 provides stable support at the bottom, ensuring the overall rigidity of the mechanism. Its action logic and safety protection system are deeply integrated. After the operator places the gear component into the cavity of the oil injection block 28 of the oil injection mechanism 2, they need to leave the closed area of the equipment safety light curtain 5. The safety light curtain 5 is fixed by the light curtain mounting block 6 and meets industrial safety standards. At this time, the first photoelectric sensor 25 installed on the photoelectric mounting plate 24 detects that the gear component has been accurately positioned, triggering the start of the pressing process. The first cylinder 8 fixed on the first cylinder mounting plate 7 receives the command and outputs downward pressure. The pressure reducing valve 9 on the valve mounting plate 10 can accurately adjust the pressing force to a suitable range according to the material of the support pad and the assembly requirements.Through the buffering effect of the internally threaded polyurethane pressure block 15 and the embedded polyurethane pressure block 21, the pressing head 44 of the rotating guide mechanism 3 is driven to apply pressure to the gear component, avoiding overpressure that could cause the support pad to break or insufficient pressing. The touch screen 11 fixed by the mounting bracket 12 provides real-time feedback on the pressing parameters. After pressing, the preset holding time is maintained to ensure the support pad is assembled stably. Then, the first cylinder 8 moves upward and returns, and the pressing head 44 is reset under the action of the compression spring 38. The turntable 40 rotates synchronously to the next material picking station, realizing the parallel cycle of pressing and picking processes. The detection and oiling processes form a closed-loop control of pressing verification, precise lubrication, and anti-interference positioning. After pressing, the color mark sensor 26 installed on the color mark mounting plate 27 immediately detects the surface of the gear component to confirm whether the support pad is successfully assembled. If a missing part is detected, the equipment alarm is triggered to prevent defective products from flowing into the next process. If the detection is qualified, the gripper cylinder 22 drives the lower gripper 30 to clamp the gear component, limiting its vertical displacement to offset the positional shift caused by the instantaneous oil pressure during subsequent oiling, and preventing the first photoelectric sensor from being detected. When the color mark sensor 26 misjudges the signal, the quantitative oil injection valve installed on the quantitative oil injection valve mounting block 23 is activated. Oil is precisely sprayed through the pre-set oil outlet of the oil injection block 28 to the critical gear meshing area. The oil injection deviation is controlled within ±5%. The oil injection sealing plate 29 and the support plate 31 work together to effectively prevent oil splashing and contamination of the equipment. After oil injection, the gripper cylinder 22 drives the lower gripper 30 to release, allowing the operator to remove the gear component that has been press-fitted and oiled. The entire process achieves automated closed-loop operation without human intervention. Through the precise coordination of various mechanisms, real-time feedback from multiple sensors, and the deep application of flexible force control technology, the equipment, with the coordinated cooperation of all components—from the support structure of the frame to the power transmission of the actuators, from the precise feedback of sensor detection to the positioning and protection of tooling components—not only specifically solves the problems of unstable quality and low efficiency in traditional manual processes, but also adapts to the assembly needs of multiple gear component models through modular design and adjustable parameters, fully meeting the high-precision and highly automated production requirements of the automotive industry.
