Description

Technical Field

[0001] This invention relates to the field of hinge production equipment technology, specifically a multi-station synchronous hinge installation machine. Background Technology

[0002] A hinge is a mechanical device used to connect two solid objects and allow relative rotation between them. Hinges can consist of movable components or be made of foldable materials. Hinges are most commonly installed on cabinets and are mainly classified by material into stainless steel hinges and iron hinges. To provide a better user experience, hydraulic hinges, also known as damping hinges, have emerged. Their characteristic is that they provide a buffer function when the cabinet door closes, minimizing the noise generated by the door colliding with the cabinet body.

[0003] In traditional hinge assembly processes, the assembly process is quite cumbersome and complex. Therefore, most of the assembly is still carried out by combining manual labor with semi-automatic equipment. This not only results in low production efficiency, but also the assembly of products is subject to human constraints, which greatly affects the quality of the products. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a multi-station synchronous hinge installation machine, which solves the problem of low assembly efficiency in traditional methods.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A multi-station synchronous hinge installation machine includes a support box, the outer cover of which is provided with a protective cover. A frame turntable is provided on the top of the support box, and multiple fixtures are provided on the frame turntable. Eight stations are provided on the top of the support box for assembling hinges. The eight stations are arranged along the circumference of the frame turntable. The eight stations are, in sequence, a glue-attaching station, a movable piece-attaching station, a rubber pad-attaching station, a base-attaching station, an eccentric nail-attaching station, an eccentric nail-riving station, a screw-driving station, and an inspection station, thus completing the assembly and inspection process of the hinges.

[0006] Preferably, the granule loading station includes a first granule vibrating plate, a second granule vibrating plate, a first material handling robot, a first material distribution component, and a first vertical vibrating feed channel. The granules stored in the first and second granule vibrating plates are vibrated and then enter the first material handling robot. The granules then enter the feed block through the first vertical vibrating feed channel. The first material distribution component separates the granules. After that, the first material handling robot lifts the granules and places them into the fixture on the machine frame turntable. Finally, the pressing cylinder presses down the granules. During the return stroke, the first material handling robot lifts the product.

[0007] Preferably, the upper movable piece station includes a movable piece vibrating plate, a first feeding robot, a second distributing component, and a second vertical vibration material channel. The movable piece stored in the movable piece vibrating plate enters the second vertical vibration material channel through vibration. The movable piece enters the feeding block through the second vertical vibration material channel. A proximity switch detects that the product has been fed into place. Then, the second distributing component separates the products. Finally, the first feeding robot clamps the connector and places it into the fixture on the machine frame turntable.

[0008] Preferably, the pad feeding station includes a pad feeding vibratory plate, a material transfer robot, a third material distribution component, and a third vertical vibration material channel. The pads stored in the pad feeding vibratory plate are vibrated and enter the third vertical vibration material channel. The pads enter the feeding block through the third vertical vibration material channel. After the product is fed into place, the third material distribution component separates the product. Finally, the material transfer robot clamps the connector and places it into the fixture on the machine frame turntable.

[0009] Preferably, the upper base station includes a base vibrating plate, a second feeding robot and a third vertical vibration material channel. The base stored in the base vibrating plate is vibrated and enters the third vertical vibration material channel. The base enters the feeding block through the third vertical vibration material channel. After the product is fed into place, the second feeding robot clamps the connector and puts it into the fixture on the machine frame turntable.

[0010] Preferably, the upper eccentric nail station includes a base vibratory plate, a second material handling robot, a receiving component, and a fourth material distribution component. The eccentric nails stored in the base vibratory plate are vibrated and enter the fourth linear vibratory material channel. The eccentric nails enter the feeding block through the fourth linear vibratory material channel. After the product is fed into place, the fourth material distribution component separates the product. Finally, the second material handling robot picks up the eccentric nails and places them into the fixture on the machine frame turntable. During the placement process, the receiving component below holds the eccentric nails in place to prevent improper placement.

[0011] Preferably, the eccentric rivet station includes a riveting machine, a pressing assembly, and a blocking assembly. The pressing assembly presses down the product, and then the riveting machine rivets the eccentric rivet.

[0012] Preferably, the screw-driving station includes two servo motors, a stroke adjustment component, two screw-driving components, and two fixing components. The fixing components on the left and right sides press down the rubber pellets to prevent the screws from rotating when they are screwed in. Then the screw-driving components move downwards so that the clamps reach the set height. Finally, the servo motors rotate to drive the screws into the product.

[0013] Preferably, the inspection station includes a material distribution hopper, a material transfer component, a material ejection component, a material discharge robot, and an eccentric nail torque detection component. The material discharge robot picks up the assembled product from the fixture and places it into the material transfer component. If it is a defective product, the material distribution hopper opens, and the material transfer component moves it to the unloading position so that the product falls from the middle of the material distribution hopper. If it is a good product, it moves to the position of the eccentric nail torque detection component to detect the torque. If the torque is not qualified, the material distribution hopper opens and the product falls from the middle of the material distribution hopper.

[0014] Beneficial effects This invention provides a multi-station synchronous hinge installation machine. Compared with the prior art, it has the following advantages: 1. This multi-station synchronous hinge installation machine can automatically complete the assembly of each component of the hinge, replacing the existing manual assembly method. This not only greatly improves production efficiency and reduces manufacturing costs, but also ensures that each component is assembled in place.

[0015] 2. This multi-station synchronous hinge installation machine uses a detection component to inspect the assembled hinges, distinguishing between good and defective products, and quickly removing the defective products. Attached Figure Description
