Description

Technical Field

[0001] The utility model relates to the technical field of coating, in particular to a stacking mechanism for coating workpieces. Background Art

[0002] Painting is an important link in modern product manufacturing process. The quality of rust-proof and corrosion-proof coating is one of the important aspects of product overall quality. The appearance quality of the product not only reflects the product protection and decorative performance, but also is an important factor in the value of the product. Due to the wide range of engineering machinery, many specifications, heavy whole machine and large parts, spraying is generally used for painting. The spraying tools include air spray guns, high-pressure airless spray guns, air-assisted spray guns and portable electrostatic spray guns. The spraying efficiency of air spray guns is low, and the high-pressure airless spray gun wastes paint. The common feature of the two is that the environmental pollution is serious, so they have been and are being replaced by air-assisted spray guns and portable electrostatic spray guns. After the workpieces are painted, they need to be stacked and transported by forklifts (or other transportation tools). Most of the existing workpieces are stacked by manually lifting one workpiece to another for stacking. This method has high labor intensity and low work efficiency. Summary of the invention

[0003] The utility model aims to overcome the shortcomings of the prior art and provide a stacking mechanism for workpiece coating which has a reasonable structure and good use effect.

[0004] To achieve the above-mentioned purpose, the technical solution provided by the utility model is: a stacking mechanism for workpiece painting, which includes a base, side panels are fixed on the top of both sides of the base, and the lower parts of the two side panels on the opposite sides are provided with mounting grooves formed by concave shapes, a supporting plate is movably installed in the mounting groove, a limiting plate is installed at the bottom of the mounting groove below the supporting plate, the limiting plate cooperates with the supporting plate, a side positioning plate is installed on the side plate below the mounting groove, a positioning area is reserved between the two side positioning plates after installation, a feeding plate is installed on the side plate below the side positioning plate, a lifting cylinder is installed on the top of the base between the two feeding plates, a lifting plate is installed on the top of the lifting cylinder, and a rear positioning plate is fixed to the top of the rear end of the lifting plate.

[0005] The support plate is fixed with mounting shafts at both ends, and the support plate is movably installed in the mounting groove through the mounting shafts. An inclined guide surface is provided at the bottom outer side of the support plate, and an arc-shaped smooth transition is adopted on the inner side of the support plate. A tension spring is connected to the end of the support plate located outside the mounting shaft, and the bottom of the tension spring is downwardly connected to the limit plate.

[0006] A side ball is installed on the side positioning plate located at one side of the positioning area, and a buffer spring is connected to the other side of the side positioning plate, and the buffer spring is connected to the side plate.

[0007] The front ends of the two side positioning plates are bent in opposite directions to form guide plates.

[0008] A lower ball bearing is installed on the top of the feeding plate.

[0009] After the utility model adopts the above scheme, the workpiece processed in the previous process is transported to the feeding plate by the conveyor belt. During transportation, the two sides of the workpiece are positioned by the two side positioning plates. When the workpiece contacts the rear positioning plate, the piston rod of the lifting cylinder extends to drive the lifting plate to move upward, and the lifting plate drives the workpiece to move upward. When the workpiece moves upward, it drives the supporting plate to rotate upward with the installation axis as the center. When the workpiece moves to the top of the supporting plate, the supporting plate rotates downward with the installation axis as the center under the tension of the tension spring to reset. When the supporting plate conflicts with the limit plate, the reset of the supporting plate is completed, and the piston rod of the lifting cylinder contracts to drive the lifting plate to move downward, so that the lifting plate can move upward. The workpiece moves to the bottom of the feeding plate for reset. The workpiece moves downward under its own gravity and is supported by the supporting plate. The conveyor belt continues to transport the workpiece to the feeding plate. The piston rod of the lifting cylinder extends out to drive the workpiece to move upward through the lifting plate. When the workpiece moves upward, it lifts up the workpiece on the upper supporting plate to stack the workpieces. When the bottom workpiece moves to the top of the supporting plate, the supporting plate is reset under the tension of the tension spring, and the piston rod of the lifting cylinder contracts to drive the lifting plate to move downward and reset. The workpiece moves downward under its own gravity, so that the bottom workpiece is supported by the supporting plate and can be stacked again. The utility model has a reasonable structure and good use effect after adopting the above scheme. BRIEF DESCRIPTION OF THE DRAWINGS
