Description

Technical Field

[0001] This utility model relates to the field of positioning and guiding equipment technology, specifically a workpiece positioning and guiding device for immersion electrophoresis lines. Background Technology

[0002] Electrophoretic coating is a coating technology in which the object to be coated is immersed in a water-soluble coating as the anode (anodic electrophoresis), and a corresponding cathode is set up. A direct current is passed between the two electrodes, and the coating is uniformly applied to the object by the physicochemical action generated by the current. The workpiece positioning and guiding device in the immersion electrophoretic coating line is a device used in the immersion electrophoretic coating production line to position and guide the workpiece, which can ensure the accurate position and stable operation of the workpiece during the electrophoresis process, and improve the quality and efficiency of electrophoretic coating.

[0003] Traditional positioning methods often employ manually adjustable bolt fixing or snap-on structures, requiring operators to frequently enter the electrophoresis tank for installation and disassembly. This is not only cumbersome and inefficient but also increases the safety risk of operators coming into contact with the electrophoresis solution. Therefore, a tank-immersion electrophoresis line workpiece positioning and guiding device is needed. Summary of the Invention

[0004] The purpose of this invention is to provide a workpiece positioning and guiding device for immersion electrophoresis lines, which solves the problems mentioned in the background art.

[0005] This application provides a workpiece positioning and guiding device for an immersion electrophoresis line, including an electrophoresis tank. Support plates are fixedly connected to both outer walls of the electrophoresis tank. Electric push rods are fixedly connected to the tops of the two support plates. Fixed sleeves are fixedly fitted to the tops of the piston rods of the two electric push rods. Mounting frames are fixedly connected to the tops of the two fixed sleeves. Positioning blocks are fixedly connected between the vertical plates of the two mounting frames. Guide grooves are formed on both inner walls along the length of the electrophoresis tank. A mounting frame is fixedly connected to the side of the mounting frame facing the guide groove. A guide wheel is rotatably connected inside the mounting frame via a rotating shaft. The guide wheel is in rolling contact with the inner wall of the guide groove. Fixed blocks are fixedly connected to the bottom ends of both sides of the positioning blocks along the width direction. Guide rods are slidably mounted on the fixed blocks and fixedly connected to the bottom inner end of the electrophoresis tank.

[0006] In use, first, according to the shape of the workpiece, place it in the square, round, or arc-shaped groove on the top of the positioning block. Then, activate the electric push rod. The piston rod of the electric push rod extends and transmits the thrust to the positioning block through the mounting frame, causing it to move smoothly downward. During this process, the mounting frame not only acts as a force transmission medium but also connects the electric push rod and the positioning block, ensuring their coordinated movement. When the positioning block descends, the guide wheels inside the mounting frame roll in the guide grooves on the inner wall of the electrophoresis tank. The two work closely together, effectively limiting the horizontal displacement (X and Y directions) and lateral sway of the positioning block, preventing uneven soaking of the workpiece due to misalignment. At the same time, the guide rods at both ends of the positioning block work in conjunction with the fixed block. The guide rods move along the guide channels within the fixed block. The sliding guide provides stable support and guidance for the lifting and lowering of the positioning block, further enhancing its stability during vertical lifting. Even when carrying heavy workpieces or experiencing impacts from the flow of electrophoretic solution, it can maintain a stable posture. As the positioning block continues to descend, it eventually immerses the workpiece completely in the electrophoretic solution in the electrophoresis tank, completing the positioning and immersion process. This process does not require manual handling or adjustment of the positioning block. Operators only need to set parameters in the control system and start the equipment to achieve automated operation, effectively avoiding direct contact between humans and the electrophoretic solution, reducing safety hazards. Furthermore, the rolling contact method between the guide wheel and the guide groove significantly reduces the frictional resistance during the lifting and lowering of the positioning block, increasing the smoothness of vertical lifting and lowering, making the entire positioning and immersion process efficient and stable.

[0007] Optionally, a drain pipe is fixedly installed through the front wall of the electrophoresis tank, and a valve is installed on the drain pipe.

[0008] By adopting the above technical solution, the electrophoresis solution in the electrophoresis tank can be discharged through the drain pipe for regular cleaning, and the valve can open or close the drain pipe.

[0009] Optionally, the top of the positioning block is provided with a square groove, a circular groove and an arc-shaped groove from left to right.

[0010] By adopting the above technical solution, it is possible to adapt to workpieces of different shapes and achieve continuous positioning of multiple types of workpieces on the same positioning block, avoiding the time cost of changing different positioning devices.

[0011] Optionally, the bottom end of the fixed sleeve is provided with an installation groove that matches the piston rod of the electric push rod, and a bolt is threaded through the outer wall of the fixed sleeve, the bolt being threadedly connected to the piston rod of the electric push rod.

[0012] By adopting the above technical solution, the firmness of the fixed sleeve installed on the electric push rod piston rod is further improved.

[0013] Optionally, the mounting bracket has an inverted L-shaped structure.

[0014] By adopting the above technical solution, direct contact between the piston rod of the electric push rod and the electrophoresis liquid can be avoided, thus protecting the electric push rod.

[0015] Optionally, the guide wheel is made of ceramic material.

[0016] By adopting the above technical solution, the wear resistance and corrosion resistance of the guide wheel are increased, and its service life is extended.

[0017] Optionally, the mounting bracket is made of 304 stainless steel.

[0018] By adopting the above technical solutions, the strength, toughness, and corrosion resistance of the mounting bracket are increased.

[0019] Optionally, the piston rod of the electric push rod extends and retracts synchronously.

[0020] By adopting the above technical solution, it is beneficial to make the positioning block rise and fall smoothly, and avoid the phenomenon of different heights on both sides.

[0021] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0022] The technical solution of this application uses an electric push rod to drive the L-shaped mounting bracket for lifting and lowering, eliminating the need for manual handling or adjustment of the positioning blocks, thus significantly improving production efficiency. It also avoids contact between personnel and the electrophoresis solution, reducing safety hazards. The cooperation of the guide wheel in the guide groove can limit the horizontal displacement and lateral swing of the positioning block. At the same time, under the action of the guide rod and the fixed block, the stability of the positioning block during lifting and lowering can be improved. Furthermore, the guide wheel can also increase the smoothness of the vertical lifting and lowering of the positioning block. Through the cooperation of the above structures, operators do not need to frequently enter the electrophoresis tank for installation and disassembly, making it convenient and practical.

Furthermore, the rolling contact between the guide wheel 3 and the guide groove 9 significantly reduces the frictional resistance during the lifting and lowering of the positioning block 12, increasing the smoothness of vertical lifting and lowering, making the entire positioning and immersion process efficient and stable.
