Description

Technical Field

[0001] The present invention relates to the technical field of automobile manufacturing, and specifically to an injection molded part surface treatment device and method thereof. Background Art

[0002] The automobile side panel is located on both sides of the automobile body. It is a large panel that covers the side of the body from the front of the vehicle to the rear, roughly in the area where the door is located and between the front and rear fenders. It separates the interior space of the automobile from the outside world. It is usually composed of an outer panel and an inner panel. The outer panel is part of the vehicle's appearance, with a smooth curved surface and smooth lines. During the injection molding process of the inner panel of the side panel, burrs may be generated at the edges, orifices and other parts. These burrs will not only affect the appearance, but may also cause poor coating adhesion or scratch the operators during subsequent processing. Generally, methods such as grinding, polishing and chemical deburring are used to ensure the smooth surface of the side panel. The dry ice machine uses extremely low-temperature dry ice particles, which are sprayed onto the object to be processed under the action of compressed air, so that the surface dirt is rapidly frozen to embrittlement and bursting. When the dry ice particles drill into the cracks of the dirt, they immediately vaporize, and their volume expands nearly 600 times instantaneously, thus taking the dirt away from the surface of the object.

[0003] Chinese Patent with the publication number CN118905884A proposes an automobile injection molded part surface treatment device and treatment method, including a mounting plate. A handle is installed at the center of the top of the mounting plate. Two groups of fixing plates are symmetrically arranged at both ends of the mounting plate. A group of support plates is arranged directly below each group of fixing plates. A group of first electric push rods is installed at the center of the top of each group of support plates. The output end of each group of first electric push rods is installed at the center of the bottom of one of the groups of fixing plates. Two groups of mounting cavities are symmetrically opened at the bottom of each group of support plates. A group of second electric push rods is arranged in each group of mounting cavities. Each group of second electric push rods is installed on the inner wall of the top of the support plate. A group of moving devices is installed on the output end of each group of second electric push rods. Each group of moving devices is located in the mounting cavity.

[0015] To better achieve the object of the present invention, the present invention also provides a method for an injection molded part surface treatment device, including the following steps: Step 1: The double-speed conveyor line of the conveying device conveys the automotive side panel. When the automotive side panel is conveyed below the special-shaped part clamping device, the output end of the lifting mechanism moves upward to lift the sliding table of the double-speed conveyor line, so that the automotive side panel on the sliding table moves upward. The automotive side panel moves to the middle side of the frame, and the output end of the lifting mechanism moves downward to return to the initial state; Step 2: The output end of the cylinder of the special-shaped part clamping device extends to drive the connecting plate to move towards the automotive side panel in the middle side of the frame. The connecting plate moving towards the automotive side panel drives the adaptive offset mechanism to move towards the automotive side panel. The rotating bracket of the adaptive offset mechanism approaches the automotive side panel, and the rotating bracket moves and closely adheres to the side wall of the automotive side panel.

9. A method for a surface treatment device of an injection molded part, for the surface treatment device of the injection molded part according to claim 8, characterized in that, It includes the following steps: Step 1: The double-speed conveyor line (51) of the conveying device (5) conveys the automobile side panel. When the automobile side panel is conveyed below the special-shaped part clamping device (3), the output end of the lifting mechanism (52) moves upward to lift the sliding table of the double-speed conveyor line (51), so that the automobile side panel on the sliding table moves upward. The automobile side panel moves to the middle side of the frame (1), and the output end of the lifting mechanism (52) moves downward to return to the initial state. Step 2: The output end of the cylinder (31) of the special-shaped part clamping device (3) extends to drive the connecting plate (34) to move towards the automobile side panel in the middle side of the frame (1). The movement of the connecting plate (34) towards the automobile side panel drives the adaptive offset mechanism to move towards the automobile side panel. The rotating bracket (312) of the adaptive offset mechanism approaches the automobile side panel, and the rotating bracket (312) moves to closely adhere to the side wall of the automobile side panel. The rotating bracket (312) adaptively rotates and adheres according to the shape of the side wall of the automobile side panel. At the same time, the rotation angle of the rotating bracket (312) is limited by the limit strip (313). The movement of the rotating bracket (312) drives the movement of the rotating plate (311). The movement of the rotating plate (311) drives the movement of the support seat (310). The movement of the support seat (310) drives the left and right movement of the slider (36). The left and right movement of the slider (36) drives the left and right movement of the C-shaped plate (37). After the C-shaped plate (37) moves to a suitable position, tighten the threaded rod (38). One end of the threaded rod (38) closely adheres to the connecting plate (34), so that the C-shaped plate (37) is quickly fixed. At this time, the special-shaped part clamping device (3) is in the shape of the automobile side panel, and the equipment debugging is completed. Step 3: The output end of the electric rotating table (22) of the flipping device (2) rotates to drive the flipping bracket (21) to rotate. The rotation of the flipping bracket (21) drives the special-shaped part clamping device (3) to rotate, driving the automotive side panel on the special-shaped part clamping device (3) to rotate. The output end of the first linear module (41) of the cleaning device (4) moves back and forth to drive the second linear module (42) and the nozzle (43) to move back and forth. The output end of the second linear module (42) moves left and right to drive the nozzle (43) to move left and right, so that the nozzle (43) moves in the horizontal direction. Cooperating with the flipping device (2) to drive the automotive side panel on the special-shaped part clamping device (3) to rotate, the nozzle (43) moves along the surface of the automotive side panel. The nozzle (43) is connected to the output pipeline of an external dry ice machine. The output pipeline of the external dry ice machine generates high-speed dry ice particles, which enter the nozzle (43) and are sprayed onto the surface of the automotive side panel through the nozzle (43) to quickly clean the burrs, grease, etc. on the surface of the automotive side panel; Step 4: After the cleaning is completed, the output end of the lifting mechanism (52) moves upward to lift the sliding table of the double-speed conveyor line (51). The special-shaped part clamping device (3) releases the cleaned automotive side panel. The output end of the lifting mechanism (52) moves downward to drive the sliding table of the double-speed conveyor line (51) to move downward, so that the automotive side panel on the sliding table returns to the double-speed conveyor line (51) again for discharging.
