Description

Technical Field

[0001] This utility model relates to the field of sheet metal parts painting pretreatment, and in particular to a sheet metal parts painting pretreatment equipment. Background Technology

[0002] In the manufacturing process of sheet metal parts, coating (such as painting or powder coating) is a crucial surface treatment step. To ensure the adhesion and quality of the coating, the sheet metal parts must be thoroughly pre-treated before coating to remove oil, impurities, and dust from their surfaces. Conventional pre-treatment processes typically include cleaning, rinsing, and drying.

[0003] Currently, for single or sparsely placed sheet metal parts, the common pretreatment method is to sequentially feed them into independent cleaning tanks, rinsing tanks, and drying chambers via a conveyor chain. However, in actual production, to improve efficiency, it is often necessary to stack multiple sheet metal parts horizontally for batch processing. When sheet metal parts are stacked horizontally, the gaps between adjacent sheet metal parts form narrow, enclosed spaces. Before entering the drying process, the liquid accumulated in the stack gaps is difficult to drain on its own due to the combined effects of surface tension and gravity. This can easily lead to water stains and spots during subsequent drying, and even affect coating adhesion due to cleaning agent residue, seriously impacting the final coating quality.

[0014] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] Please refer to Figures 1 to 4 This utility model provides a sheet metal parts painting pretreatment equipment, including a lifting mechanism 5, a moving mechanism 4, a flipping mechanism 6, a sheet metal clamp 7, and a processing box. The processing chamber is equipped with two partitions, which divide the processing chamber into a cleaning chamber 1, a soaking chamber 2, and a drying chamber 3 in sequence. The moving mechanism 4 is located on one side of the processing box, and the moving end of the moving mechanism 4 is connected to the lifting mechanism 5; The lifting end of the lifting mechanism 5 is connected to the tilting mechanism 6; The flipping end of the flipping mechanism 6 is connected to the sheet metal fixture 7.

[0016] In this embodiment, the sheet metal clamp 7 includes a bracket 71, an L-shaped rod 73, a clamping plate 74, and a clamping electric cylinder 72; Two sets of clamping electric cylinders 72 are installed on the bracket 71; The piston rod of the clamping electric cylinder 72 is connected to the horizontal part of the L-shaped rod 73; The vertical part of the L-shaped rod 73 is fixedly connected to the clamp 74; The inner wall of the clamping plate 74 is provided with multiple clamping grooves at equal intervals along the vertical direction; In use, drive one of the clamping electric cylinders 72 to bring the two clamping plates 74 closer together. Then insert both ends of the sheet metal parts into the corresponding clamping slots. After installing multiple sheet metal parts, drive the other clamping electric cylinder 72 to clamp them, thereby fixing the multiple sheet metal parts between the two clamping plates 74.

[0017] In use, the sheet metal clamp 7 clamps multiple horizontally arranged sheet metal parts, and together with the lifting mechanism 5 and the moving mechanism 4, they are placed into the cleaning chamber 1. The cleaning fluid in the cleaning chamber 1, together with the water circulation mechanism, continuously washes the sheet metal parts. After cleaning, the flipping mechanism 6 rotates the sheet metal clamp 7 by 90°, so that the sheet metal parts are set vertically, and the residual cleaning fluid in the adjacent sheet metal parts can be discharged. Then, the lifting mechanism 5 and the moving mechanism 4 place them into the soaking chamber 2, and the clean water in the soaking chamber 2 washes away the residual cleaning agent on the sheet metal parts. Finally, they are moved to the drying chamber 3 for drying.

[0018] This application integrates three major functions: cleaning, rinsing, and drying. Through the coordinated operation of the moving mechanism 4 and the lifting mechanism 5, it achieves automatic and precise transfer of sheet metal parts between the three processing stations. The entire pre-treatment process requires no manual intervention to handle or flip the parts, overcoming the shortcomings of traditional methods such as low efficiency and high labor intensity. It is particularly suitable for mass production, and production efficiency is greatly improved. By setting up a flipping mechanism 6, after the cleaning process and before the rinsing and drying processes, the horizontal sheet metal parts are flipped 90° to become vertical. This key operation breaks the closed space formed by the horizontal stacking of adjacent sheet metal parts, allowing the cleaning liquid and water accumulated in the interlayer to flow out fully by gravity. This fundamentally avoids water stains and spots caused by liquid residue and ensures the complete removal of cleaning agent, providing a clean and dry base for subsequent coating and greatly improving the adhesion of the coating and the quality of the final product.

[0019] In this embodiment, the flipping mechanism 6 includes a fixed arm 61, a flipping arm 62, a rotating shaft 63, a control rod 64, and a control cylinder 65; One end of the bottom of the flipping arm 62 is fixedly connected to the sheet metal clamp 7, and one end of the top of the flipping arm 62 is fixedly connected to the rotating shaft 63. Both ends of the rotating shaft 63 are rotatably connected to the inner wall of the fixed arm 61. One end of the rotating shaft 63 extends outward and is fixedly connected to the control rod 64. One end of the control cylinder 65 is rotatably connected to the control rod 64, and the other end of the control cylinder 65 is rotatably connected to the side wall of the fixed arm 61. In use, the control cylinder 65 drives the control lever 64 to rotate the rotating shaft 63, thereby realizing the rotation control of the tilting arm 62.

[0020] In this embodiment, both the lifting mechanism 5 and the moving mechanism 4 adopt ball screw mechanisms.

[0021] In this embodiment, a water inlet pipe is provided on the surface side wall of the cleaning chamber 1, and a water outlet pipe is provided on the back side wall of the cleaning chamber 1. The water inlet pipe is connected to the water pump and the water outlet pipe in sequence through the pipeline to realize water circulation, thereby rinsing the sheet metal parts in a horizontal state.

[0022] In this embodiment, a support frame is provided on one side of the surface of the drying chamber 3, and a hot air blower is installed on the support frame. The hot air blower is located directly above the opening of the drying chamber 3, and the hot air generated by the hot air blower quickly dries the adjacent sheet metal parts.
