Description
Technical Field
[0001] The utility model relates to the technical field of hinge assembly, in particular to a hinge production line with a detection function. Background Art
[0002] A hinge is a mechanical device used to connect two relatively independent solid bodies, allowing them to rotate relative to each other. Hinges are very commonly used as connectors for furniture doors, utilizing the principle of a living hinge to allow the door to open and close around an axis. A hinge is primarily assembled from a cup head, rocker arm, arm body, triangular piece, laminated plates, base, U-shaped staples, damping tube, torsion spring, plastic round tube, and several connecting staples and screws. Hydraulic hinges utilize high-density oil flowing through the damping tube to achieve a cushioning effect, ensuring a gentle closing even when the door is slammed hard. During overall hinge assembly, the connections between the various components must be aligned, ensuring that the matching connection holes and screw holes in the arm body, base, inner rail assembly, and rocker arm are aligned. The components are then assembled together using rivets. With the exception of the pivoting cup head, the arm body is already assembled with the other components, collectively known as the arm body assembly.
[0003] The existing technology usually assembles the various parts of the hinge in a certain order, then rivets the connecting nails by riveting, finally completing the assembly of the hinge, and then testing the hinge. In actual application, this common assembly method is not scientific and reasonable in the assembly order of the various parts of the hinge, making it difficult to ensure work efficiency. It is also prone to assembly errors or defective products. Once a defective product is detected, when disassembling the defective product for reuse, the riveted part of the rivet needs to be ground off because the nailing and riveting are carried out simultaneously, which can easily damage other accessories such as the arm body. The hinge can only be disassembled after the rivets are removed. The rework process is cumbersome, time-consuming and labor-intensive, wasting a lot of human resources and increasing the production costs of the enterprise. Therefore, production efficiency and product quality need to be improved.
[0004] Currently, hinge opening and closing detection usually uses manual arms to rotate the hinges for opening and closing detection. However, since the human arm cannot ensure that the hinge is completely rotated horizontally during the measurement process and there is still lateral force, when conducting the detection, it is necessary to wait for the opening and closing process of the buffer hinge under inspection to be completed and then restore it before the next buffer hinge can be tested. In the process of testing large quantities of buffer hinges, the buffer closing time of common buffer hinges varies from 4 to 8 seconds. Waiting for the buffer closing time of the buffer hinge will greatly affect the detection efficiency. Utility Model Content

The production line includes at least a loading station, an assembly station, a riveting station and a feeding station, and also includes a detection station. The detection station is set before the riveting station. When a defective hinge is detected, it is only necessary to directly remove the rivet in the hinge 8 and disassemble the components for reuse. There is no need to grind off the riveted part, which saves manpower and time and avoids damaging the arm body. The inspection station includes a rotating disk 1 and a loading mechanism 2, a cup head pressing mechanism 3, a cup head closing mechanism 4, a cup head opening mechanism 5, and a feeding mechanism 6 arranged along the rotation direction of the rotating disk 1. The rotating disk 1 is provided with several inspection carriers 11 that can accommodate the hinge 8.

The transfer clamp 21 includes a first clamp block 213 and a second clamp block 214 that are movable and arranged close to or apart on both sides. The first clamp block 213 and the second clamp block 214 have a first step surface 2131 and a second step surface 2141 on the opposite end surfaces for clamping the lower surface of the arm body assembly 81. The first clamping jaw 211 also has an upper pressure block 215 that abuts against the upper surface of the arm assembly 81. A rotating base 25 is provided at the bottom of the intermediate transfer tool 22.

The feeding jaw 61 clamps the hinge on the detection carrier 11 to feed the material. The structure of the feeding jaw 61 is the same as the first jaw 211. The sorting chute 62 is arranged on one side of the feeding jaw 61. The feeding jaw 61 is slidably arranged on the guide rail 63. After the feeding jaw 61 clamps the hinge 8 on the detection carrier 11, it moves along the guide rail 63 to the top of the sorting chute 62 and releases it. The sorting chute 62 includes a finished product chute 621 and a defective product chute 622. The sorting chute 62 feeds the hinge 8 through the finished product chute 621 or the defective product chute 622 according to the detection result of the detection camera 55.
[0038] The intermediate transfer tool 22 and the rotating base 25 facilitate the hinge 8 to be placed directly on the inspection carrier 11. The cup head pressing mechanism 3 presses the cup head 82 downward, and the cup head 82 slowly closes. The rotating disk has an appropriate time interval for the cup head 82 to move. The cup head closing mechanism 4 pushes the cup head 82 that has not been completely closed to the closed position. The cup head opening mechanism 5 then opens the cup head 82 and uses the inspection camera 55 to observe whether it is open. Those that meet the set requirements pass through the finished product chute 621 to enter the next process, and the rest enter the defective product chute 622 for rework.
[0039] The first, second and cup head opening mechanisms 3, 4 and 5 can detect the buffer hinge 8 from opening to buffer closing and then opening again, while the detection camera 55 and the discharge mechanism 6 sort the hinge 8 without stopping, which effectively improves the detection efficiency of the hinge 8. It can also be applied to the detection of various hinges such as straight arm type, small curved arm type, large curved arm type hinge and aluminum frame hinge.
