Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of cleaning devices, in particular to a cleaning device for producing magnesium alloy handles of electric vehicles. Background Art
[0002] Magnesium alloy handlebars for electric vehicles are a key component for controlling and supporting electric vehicles. Typically made of magnesium alloy, handlebars are essential for drivers to operate electric vehicles, primarily for controlling speed and direction. They offer a good grip, comfortable hand support, and an enhanced riding experience. Handles not only provide control but also provide stable support, allowing riders to ride safely and comfortably. Magnesium alloys can be easily designed into streamlined shapes, enhancing the overall appearance of electric vehicles. The lightness and durability of magnesium alloy handlebars for electric vehicles meet daily travel needs and enhance the overall riding experience. For high-performance electric vehicles, magnesium alloy handlebars offer excellent strength and lightweight design, supporting high-speed travel and complex maneuvers. Due to their lightweight, corrosion-resistant, and high-strength design, magnesium alloy handlebars for electric vehicles have become an indispensable component in modern electric vehicles. They not only enhance the performance of electric vehicles, but also provide a better riding experience and greater design freedom.
[0003] The existing cleaning work of electric vehicle handles is to place the handles in a cleaning device for cleaning, which requires multiple processes. When the handles are transferred through each of these cleaning methods, accidents such as the handles falling may occur, resulting in damage to parts. In addition, the "Utility Patent Publication No. CN221361664U discloses a cleaning device" uses a six-axis robot to drive the components for cleaning. This method requires multiple motors to cooperate with the clamping of parts, and a certain reaction speed is required when clamping the components. It is inefficient to not grab the parts immediately. Summary of the Invention

[0014] Working principle: Place the brake handle in the loading box, and then place the loading box on the sliding slot. The sliding slot is connected to an inclined slide to facilitate the loading box to slide to the side of the moving inclined block. Then start the cylinder to drive the moving plate to move downward, thereby driving the lower plate and the first moving rod to move downward. The downward movement of the first moving rod drives the rolling rod to move the moving inclined block to the left through the inclined surface set on the moving inclined block. At this time, the loading box is slid to the bottom of the limit clamp by gravity by the same loading box at the rear end. Then the lower plate moves to the top of the limit clamp, press the fixed bracket downward to move the contact brake handle and the brake handle The round head on the limit clamp is pressed between the limit clamps by the inclined surface provided on the limit clamp. When pressed, the limit clamp moves backward. Then, after the upper end of the brake handle passes through the protrusion in the middle of the limit clamp, the limit clamp is pushed toward the middle under the action of the third spring and the third slide bar to limit the brake handle. Then, the cylinder is started to pull the moving plate back to its original position, and the fixed bracket is also pulled upward to its original position through the second slide bar and the second spring, thereby pulling the brake handle out of the loading box, and when the moving plate returns to its original position, the rolling rod moves upward, and the moving oblique block also returns to its original position through the first slide bar and the first spring. The loading box is thereby pushed to the collecting tank for collection, and the next loading box on the sliding tank moves to contact the side surface of the moving inclined block, and then the motor in the moving car is started to drive the first gear to rotate, thereby driving the moving car to move on the track. When the moving car moves to the top of the ultrasonic cleaning tank, the inclined surface of the limit clamping block contacts the inclined surface set on the limit plate, and the fixed bracket is pulled down to the inside of the ultrasonic cleaning tank to start the ultrasonic cleaning tank to clean the brake handle. At the same time, the second gear contacts the tooth plate to engage and drive the fixed block to rotate to prevent uneven cleaning. Then the material taking device leaves the limit plate and is fixed. The block returns to its original position under the action of the torsion spring, and then passes through the washing tank for washing. The material-retrieving device performs the same operation, and then moves to the drying equipment for drying. Then it moves to the top of the placement tank, and the cylinder is started to drive the second moving rod to move downward, and the fixed bracket is pressed down by the limit clamp. The limit bevel contacts the upper end of the placement tank, and then the placement tank moves the limit clamp backward through the inclined surface of the limit bevel, thereby releasing the limit on the brake handle, and falls to the middle of the placement tank for collection. Then the cylinder drives the moving plate back to its original position, and the mobile car starts to drive the fixed block back to its original position and repeat the operation.
