Description

Technical Field

[0001] This invention relates to the field of workpiece processing equipment technology, and in particular to a middle frame assembly machine. Background Technology

[0002] A workpiece refers to the object being processed during the machining process. It can be a single part or a combination of several parts fixed together. When processing a workpiece, it is usually necessary to use corresponding processing equipment. A shielding box is a metal body that uses conductive or various shapes to shield electromagnetic energy within a certain space and is used to suppress radiation interference. In the processing of shielding boxes, it is usually necessary to use corresponding assembly equipment.

[0003] Current mid-frame assembly methods suffer from several drawbacks during shielding box processing. Workers are prone to hand injuries, workpiece deformation occurs, and the workload is heavy. Furthermore, contact pieces cannot be installed manually, resulting in insufficient equipment flexibility and stability, directly impacting workpiece processing efficiency. Additionally, the current mid-frame assembly equipment lacks operational controllability, and the workpiece finishing quality needs improvement. Therefore, we propose a mid-frame assembly machine. Summary of the Invention

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a mid-frame assembly machine, comprising a machine body, a frame connected to the bottom of the machine body, a shielded box vibratory feeder, a contact piece vibratory feeder one, and a contact piece vibratory feeder two respectively mounted on the upper end of the frame, and an electromagnetic vibration mechanism connected to the bottom end of each of the shielded box vibratory feeder, contact piece vibratory feeder one, and contact piece vibratory feeder two for vibrating material feeding, so that the contact piece parts and the shielded box are sequentially exported; a first guide rail is provided on one side of the shielded box vibratory feeder, a second guide rail is provided on one side of the contact piece vibratory feeder one, and a third guide rail is provided on one side of the contact piece vibratory feeder two; an electromagnetic vibrator is installed at the lower end of the first guide rail on one side of the shielded box vibratory feeder for vibrating material feeding; a photoelectric sensor is provided at the output end of the first guide rail on one side of the shielded box vibratory feeder to sense whether the contact piece has reached the position; a shielded box is provided below the photoelectric sensor. A placement platform is provided, with a first operating table on one side of the shielding box placement platform. A shielding box robot arm is provided above the shielding box placement platform for picking up shielding boxes. The bottom of the shielding box robot arm is connected to a suction cup to adsorb the contact pieces. The position of the shielding box robot arm is adapted to the position of a photoelectric sensor to form an operating position correspondence. That is, after the photoelectric sensor detects, it drives the shielding box robot arm to pick up the shielding box. A first robot arm is provided above the first operating table, and a second operating table is provided on one side of the first operating table. A second robot arm is provided above the second operating table. Both the first and second robot arms are connected to a mounting plate. The first and second robot arms work together and operate synchronously. A slide rail is provided at the bottom of the second operating table, and the bottom of the second operating table slides with the slide rail, so that the second operating table can move back and forth.

[0006] A first telescopic cylinder is connected to one side of the second operating table for moving the second operating table back and forth, so that the middle frame on the second operating table can be switched between positions adapted to the second robot and the pressing guide plate as needed. A rotating mechanism is provided at the output end of the third guide rail on one side of the contact plate vibratory plate for rotating the contact plate to adapt to the installation position of the middle frame. A core groove is connected to one side of the rotating mechanism, and a pressing cylinder is installed at the upper end of the core groove. The core groove is installed on the rotating mechanism, and the pressing cylinder presses the contact plate through the core groove to the feeding block. A second telescopic cylinder is installed on one side of the feeding block for pushing the contact plate to the appropriate position of the pressing guide plate. A pressing cylinder is installed at the upper end of the pressing guide plate, and the output end of the pressing cylinder is adapted to the position of the pressing guide plate for pressing and fixing the contact plate.

[0007] The second robotic arm is connected to a mounting plate at its upper end. A third telescopic cylinder is connected to one side of the sliding plate. The third telescopic cylinder serves as a driving mechanism, and it drives the first robotic arm and the second robotic arm to be mounted on the same mounting plate.

[0008] Both the first and second contact plate vibratory disks are equipped with mounting platforms at their bottom ends. The mounting platforms are threadedly connected to the frame and are used to adjust the height of the first and second contact plate vibratory disks. Rubber blocks are fixed on the mounting platforms to cooperate with the buffer support of the vibratory disks to limit their movement.

[0009] The second and third guide rails are both set at an angle of 15°, and the input end of the guide rails is higher than the output end, which facilitates gravity-driven material feeding;

[0011] The photoelectric sensor is communicatively connected to the drive mechanism of the shielded box robot. When the photoelectric sensor detects that the workpiece has fallen onto the shielded box placement platform, the shielded box robot moves immediately.

[0012] A middle frame is placed on the upper surface of the first and second operating tables. The opening diameter of the first and second robotic arms is adapted to the middle frame for synchronous grasping. During this process, the first robotic arm moves from the first operating table to the second operating table; the second robotic arm moves from the second operating table to the material box.

[0014] The bottom ends of the shielded box vibratory plate, contact plate vibratory plate one, and contact plate vibratory plate two are all equipped with buffer supports to enhance the vibration protection effect. The fixed round hole above the mounting platform corresponds to the rubber pad at the bottom of the vibratory plate and plays a limiting role. The rubber block fixed on the mounting platform cooperates with the buffer support of the vibratory plate to play a limiting role.

[0015] The output end of the first guide rail on one side of the vibratory feeder of the shielding box is also provided with a moving cylinder. A fourth telescopic cylinder is connected to one side of the moving cylinder. The moving cylinder is the up-and-down moving cylinder of the shielding box robot, and the fourth telescopic cylinder is the left-and-right moving cylinder of the shielding box robot.

The first robotic arm 7 clamps the assembly box onto the second operating table 10. The bottom of the second operating table 10 is connected to a slide rail 12, which is pulled backward by the first telescopic cylinder 11 until the contact pieces vibrate. The workpiece is rotated 75° to adapt to the corresponding track by moving plate 4 and contact plate vibrating plate 25.
