Technical Field

[0001] This utility model relates to the field of hinge manufacturing technology, and in particular to an assembly line for a 90-degree hinge and a hinge body. Background Technology

[0002] Chinese patent application number CN202010675429.6 discloses a fully automated hinge assembly production line that realizes the automated production and assembly of hinges.

[0003] However, the assembly equipment of this type of hinge assembly production line is arranged in a straight line, which makes the area occupied large. The semi-finished products between the equipment require a large number of transfer equipment, which makes the production process complicated. The large size of the equipment also makes the arrangement of the feeding mechanism more dispersed, which makes it inconvenient for the staff to operate.

[0004] Therefore, this case proposes a hinge assembly production line with a ring structure to reduce equipment size and the number of transfer devices required. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as large equipment size and numerous transfer nodes, by proposing an assembly line for a 90-degree hinge and the hinge body itself.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design an assembly line with a 90-degree hinge, including a turntable, on the upper surface of which multiple sets of placement racks for placing assemblies are arranged at equal intervals around the circumference of the turntable, and sequential assembly mechanisms are arranged at equal intervals around the periphery of the multiple sets of placement racks.

[0008] The sequential assembly mechanism includes the following components arranged in sequence: arm loading, cylinder loading, four-hole and spring loading, first screw-on mechanism, screw loading, second screw-on mechanism, bag loading, U-shaped screw loading, and material discharge and distribution.

[0009] The inner side of the multiple sets of placement racks is also provided with arm body oiling, a first nailing mechanism and a second nailing mechanism. The arm body oiling is set between the arm body loading and the oil cylinder. The first nailing mechanism and the four holes are set in correspondence with the spring. The second nailing mechanism and the screw are set in correspondence with the screw.

[0010] Preferably, the arm loading includes a loading conveyor belt, and a robotic arm for gripping the semi-finished arm and transporting it to the placement rack is installed on the side of the loading conveyor belt near the turntable.

[0011] Preferably, the arm body oiling includes a liquid pump facing the placement rack.

[0012] Preferably, the cylinder loading includes a conveyor frame, and a robotic arm is installed on the side of the conveyor frame near the turntable for placing the cylinder components in the conveyor frame into the semi-finished arm body.

[0013] Preferably, the four-hole component and spring assembly includes two sets of conveyor racks, which are used to store and transport the four-hole component and the spring component respectively. A robotic arm is installed on the side of the two sets of conveyor racks near the turntable to place the four-hole component and the spring component into the semi-finished arm body.

[0014] Preferably, both the first rivet insertion mechanism and the second rivet insertion mechanism include a cylinder and a feeding trough, and the first rivet turning mechanism and the second rivet turning mechanism are used to fasten the first rivet and the second rivet.

[0015] Preferably, the container includes a conveyor rack for storing and transporting the containers, and a robotic arm for placing the containers into the semi-finished product of the arm is installed on the side of the conveyor rack near the turntable.

[0016] Preferably, the bagging unit includes a conveyor rack for storing and transporting bagging parts. A robotic arm for placing the bagging parts into the semi-finished product arm is installed on the side of the conveyor rack near the turntable. The bagging unit includes a cylinder and a material trough.

[0017] Preferably, the material discharge and distribution includes a visual inspection camera and a material distribution cylinder.

[0018] A hinge body, assembled sequentially using the aforementioned 90-degree hinge assembly line, includes a semi-finished arm body. A hydraulic cylinder component is internally fixedly engaged within the semi-finished arm body. A pocket component is mounted at one end of the hydraulic cylinder component via a four-hole component and a sharp-point component. One end of the four-hole component and the sharp-point component is pinned to the pocket component via a U-shaped pin. The other ends of the four-hole component and the sharp-point component are pinned to the semi-finished arm body via a first rivet and a second rivet, respectively.

[0019] The present invention provides an assembly line for a 90-degree hinge and a hinge body, the advantages of which are:

[0020] The turntable allows for periodic control of its rotation to achieve sequential assembly, resulting in a circular assembly line with a more compact feeding device that is easier for workers to operate. Furthermore, the shape of the placement rack on the turntable matches the extension and retraction state of the hinge body, preventing stress on spring components and other structures, thus improving installation accuracy and yield.

[0021] The reasonable arrangement of each step in this case allows for better assembly of the hinge body, and the assembly process does not require flipping or other operations on the semi-finished products in the shelf, thus improving assembly efficiency. Attached Figure Description

The turntable 1 rotates and transfers the arm body semi-finished product A1. The arm body semi-finished product A1 is first lubricated by arm body oiling X2. Then, the arm body semi-finished product A1 is installed with the oil cylinder X3. After that, the four-hole component C1 and the spring component C3 are combined with the arm body semi-finished product A1 by installing four holes and springs X4. At the same time, the first rivet insertion mechanism X5 inserts the first rivet C2 for fixation. After the first rivet is inserted, the semi-finished product rotates to the first rivet insertion mechanism X5. 6. Tighten the first rivet C2. After tightening, insert the rivet part D1 through the rivet inserter X7. At the same time, insert the second rivet D2 through the second rivet insertion mechanism X8. After inserting the second rivet D2, the semi-finished product is rotated to the second rivet rotation mechanism X9 for tightening the second rivet D2. Then, insert the pocket part E1 through the pocket inserter X10. Combine the U-nail part F1 through the U-nail inserter X11. Finally, discharge the assembled part through the material discharge and distribution X12.

[0037] Furthermore, the arm loading X1 includes a loading conveyor belt for conveying the arm body semi-finished product A1.
