Description

Technical Field

[0001] This invention relates to the technical field of mobile phone component manufacturing, specifically to a flip-top disassembly device for a mobile phone welding fixture. Background Technology

[0002] When assembling mobile phone components, small parts and glass are placed on the front of the welding fixture, while welding is performed on the back. Since the weld is at the back of the component, welding inspection requires manual flipping of the fixture. After flipping, a cover plate is magnetically attached to the bottom plate of the fixture, which must be manually removed before the welding fixture and the component can be placed into the weld inspection station. This process is dangerous due to the manual flipping of the fixture, and the manual flipping and cover removal are inefficient and cannot meet the production line's needs. Summary of the Invention

[0003] To address the aforementioned issues, this invention provides a flipping and unpacking device for mobile phone welding fixtures. This device automatically flips the fixture over and removes the cover plate to facilitate subsequent inspection and material unloading. This device solves the dangers and uncertainties of manually flipping fixtures, saves the entire production line's operating time and manpower, thereby indirectly improving the overall production efficiency of the line.

[0004] A flip-up and cover-removal device for a mobile phone welding fixture, characterized in that it comprises:

[0006] The fixture flipping module includes a lifting frame, a hollow rotating platform mounting plate, a hollow rotating platform, a lifting drive cylinder, and a gripper assembly. The lifting drive cylinder drives the hollow rotating platform mounting plate to move up and down along the lifting frame. The hollow rotating platform is provided at the front end of the hollow rotating platform mounting plate. The hollow rotating platform is provided with a mounting frame protruding forward. The mounting frame is provided with a gripper assembly, which is used to grip the two sides of the fixture.

The first horizontal module is arranged along the crossbeam of the gantry frame. The output end of the first horizontal module is provided with the second lifting module. The output end of the second lifting module is fixedly mounted with a connecting bracket. Pneumatic gripper assemblies are respectively arranged on both sides of the connecting bracket. The lower two ends of the connecting bracket are provided with downward protruding stop bar mechanisms.

[0008] The cover plate conveyor line is used to transfer the cover plates removed from the cover plate disassembly module to the forward workstation.

[0009] And the base;

[0010] A streamline module is provided at the upper front end of the base. Above the upper streamline, gripper assemblies and pneumatic gripper assemblies are arranged sequentially along the material travel direction. A fixture flipping module is arranged on the material inlet side of the base, and a cover plate removal module is arranged on the material outlet side of the base. The fixture flipping module flips the fixture and places it back on the upper streamline. The upper streamline drives the flipped fixture to the bottom of the pneumatic gripper assembly. The pneumatic gripper assembly removes the cover plate from the fixture and transfers it to the input end of the cover plate conveyor line.

[0011] Its further features are:

[0012] It also includes a feeding mechanism, which includes a cover plate placement cavity, in which the cover plate is placed, and the bottom of the feeding mechanism is fixedly mounted to the rear side of the input end of the cover plate conveyor line.

[0013] The upper streamline step has N workstations, and the workstation of the fixture flipping module is synchronously equipped with N sets of fixture flipping modules, and the workstation of the cover plate removal module is synchronously equipped with N sets of cover plate removal modules, where N is a natural number ≥ 2.

[0014] The bottom of the cover plate placement cavity is provided with a second linear module. When a NG product appears on the cover plate, the second linear track module drives the cover plate placement cavity to be placed at the rear position of the pneumatic gripper assembly corresponding to the first horizontal module. The pneumatic gripper assembly drives the cover plate to be added to the input end position of the cover plate input line.

[0015] The gripper assembly includes a first gripper cylinder, a left gripper, a right gripper, a gripper connector, and a first horizontal support rail. The first gripper cylinder is fixedly mounted on the central control rotating platform, and its two output ends are respectively fixedly connected to the corresponding left gripper and right gripper through the gripper connector. The bottoms of the left gripper and right gripper are respectively supported on the first horizontal support rail through guide rail pairs. The first horizontal support rail is fixedly mounted on the surface of the mounting frame.

[0016] The lifting frame is equipped with a lifting rail, and the lifting frame is also equipped with an upper hydraulic buffer and a lower hydraulic buffer. The back side of the hollow rotating platform mounting plate is respectively embedded in the corresponding lifting rail. The upper and lower parts of the hollow rotating platform mounting plate are limited by the upper hydraulic buffer and the lower hydraulic buffer, respectively. The upper hydraulic buffer and the lower hydraulic buffer ensure the reliable height position of the hollow rotating platform mounting plate.

[0017] The pneumatic gripper assembly includes two gripper mechanisms on both sides and a second gripper cylinder. The base plate of the connecting bracket is provided with a second horizontal support rail on both sides. The second gripper cylinder is fixedly mounted at the bottom center of the base plate.

The upper part of the connecting rod is fixedly connected to the base plate, and the lower part of the connecting rod is fixedly installed with the pressure block. The pressure block is used to press and hold the outer frame of the fixture, so that the grippers on both sides separate the upper cover plate and the fixture.

[0019] After adopting the above technical solution, the fixture, carrying the welded components, enters the upper flow line. The upper flow line transports the fixture step-by-step to directly below the gripper assembly of the fixture flipping module. The gripper assembly moves down to clamp the fixture, then moves up and flips it. Afterward, the fixture flipping module flips the fixture and places it back on the upper flow line. The upper flow line carries the flipped fixture to below the pneumatic gripper assembly. The pneumatic gripper assembly moves down to remove the cover plate on the fixture and transfers it to the input end of the cover plate conveyor line. After flipping and removing the cover plate, the component flows into the subsequent weld inspection station for inspection. It automatically flips the fixture over and removes the cover plate to facilitate subsequent inspection and unloading. This equipment solves the danger and uncertainty of manually flipping fixtures, saves the entire line's operating time and manpower, and thus indirectly improves the overall production efficiency of the line.

[0041] In practice:

[0042] The jig 60 has an overall length of 236mm. During the flipping process, the center of the jig 60 is concentric with the center of the hollow rotating platform 23, ensuring that the position remains unchanged after flipping.

[0043] The lifting drive cylinder 24 is specifically a thin cylinder; the jig 60 has a rotation radius of 128mm and a stroke of 200mm to avoid interference with the upper streamline during rotation; the two jig flipping modules operate at a distance of 301.25mm at the same time, and when the grippers are open, the distance between the left and right grippers is 288mm, so the two mechanisms will not interfere with each other when they operate at the same time.

[0044] Its working principle is as follows: The fixture, carrying the welded components, enters the upper flow line. The upper flow line transports the fixture step-by-step to directly below the gripper assembly of the fixture flipping module. The gripper assembly moves down to hold the fixture, then moves up and flips it. After that, the fixture flipping module flips the fixture and places it back on the upper flow line. The upper flow line carries the flipped fixture to below the pneumatic gripper assembly. The pneumatic gripper assembly moves down to remove the cover plate on the fixture and transfers it to the input end of the cover plate conveyor line. After flipping and removing the cover plate, the component flows to the weld inspection station for inspection. It automatically flips the fixture over and removes the cover plate to facilitate subsequent inspection and unloading. This equipment solves the danger and uncertainty of manually flipping fixtures, saves the entire line's operating time and manpower, and thus indirectly improves the overall production efficiency of the line.
