Description
Technical Field
[0001] This utility model relates to a front door opening and closing structure for a 3D-AOI inspection machine, belonging to the technical field of door opening and closing structures. Background Technology
[0002] 3D-AOI inspection equipment / machines are essential inspection equipment in SMT factories. They can be used to detect defects in PCBA boards. Currently, AOI used in SMT processing plants to inspect the quality of chip mounting and soldering includes 2D and 3D AOI technologies. With the development of technology, equipment in various fields is becoming more diversified, miniaturized, and high-performance, placing higher demands on the precision, strength, and appearance of sheet metal casings. These casings need to be aesthetically pleasing, corrosion-resistant, and easy to clean. Therefore, the sheet metal structural components of the casings integrate materials science, mechanical design, and manufacturing processes, focusing on the industrial needs of lightweight and high protection. Currently, inspection equipment uses high-strength steel and square tubing welded together, with a transparent acrylic window installed in the middle section for visualization. The overall weight is relatively heavy.
[0003] Existing visualization windows all use sheet metal doors, which have a large opening arc that is higher than the height of personnel, resulting in a large gas spring stroke and a large rebound when opening. The overall weight of the door is heavy, making installation difficult and requiring multiple people to assemble and adjust it. In addition, the large opening arc and the center of gravity being at the front result in a large force when opening and closing the door, which is inconvenient for people of different body types. The monitor is usually mounted externally, occupying the horizontal space of the inspection equipment, which has a certain impact on compact connection. There is also a certain risk of collision with the monitor when opening and closing the door. The opening method of sheet metal doors is usually controlled by the gap between the guide wheel and the guide groove. If the gap is too large, it will cause the door to shake and generate noise when opening and closing. If the gap is too small, it will affect the smoothness and increase friction. Therefore, this application provides a front door opening and closing structure for a 3D-AOI inspection machine to meet the requirements. Utility Model Content
[0004] (a) Technical problems to be solved The purpose of this utility model is to provide a front door opening and closing structure for a 3D-AOI inspection machine to solve the above-mentioned problems, thereby addressing the technical issues in the prior art such as large gas spring stroke leading to large rebound when opening, heavy overall weight of the opening and closing door making installation difficult, large opening arc causing inconvenience for people of different body types, and externally mounted monitor occupying the horizontal space of the inspection equipment.

Each set of support frames consists of a vertical plate and a support plate horizontally connected to the top of the vertical plate. A guide groove plate for guiding the opening and closing trajectory of the front door is vertically connected to the inner side of the vertical plate. The back top surface of the front door is movably connected to a two-fold adapter bracket via a hinge to form the main two-fold door structure. The front door moves up and down along the extension direction of the guide groove plate. Main bearing assemblies are installed on both sides of the front door, and the main bearing assemblies are placed inside the groove cavity of the guide groove plate. The front of the intermediate connecting plate is movably connected to the second hinge via a hinge adapter bracket. The front part of the second fold plate is connected to the second fold adapter bracket, and the column part of the gas spring is connected to the bottom of the second fold plate with its cylindrical part facing upward.
[0006] Preferably, the main bearing assembly consists of a bearing, a washer, and a rubber-coated wheel. The bearing and the washer are fitted into the rubber-coated wheel and connected together by screws. The screws are used to lock the bearing and the washer so that the bearing can rotate smoothly without jamming.
[0007] Preferably, a display is embedded in the front of the front door, and the vertical height of the front door does not exceed the vertical height of the upright plate.
[0008] Preferably, the distance between the front of the pallet and the front of the intermediate connecting plate is equal to the width of the two-fold plate.
