Description

Technical Field

[0001] The utility model relates to the technical field related to rivet equipment, in particular to a universal stapling and riveting equipment. Background Art

[0002] Rivet connection is a method of connecting multiple parts by using axial force to thicken the nail rod in the rivet hole of the part and form a nail head. For the hardware assembly industry, rivet connection is an indispensable process. And nailing is one of the key steps in the riveting process. The accuracy and efficiency of nailing determine the riveting accuracy of the parts and the efficiency of the riveting process.

[0003] In the existing riveting process, manual nailing is usually used, and then the stamping process is performed to achieve the riveting of multiple parts. However, relying on manual nailing before stamping is not only very dangerous and inefficient, but also has high labor costs.

[0004] Therefore, in order to avoid the defects of manual stapling, which is dangerous, inefficient and costly, the use of mechanical equipment for automatic stapling is one of the solutions currently adopted in the industry.

[0005] For example, Suzhou Derun Precision Manufacturing Co., Ltd. has disclosed a universal semi-automatic riveting device (patent publication number: CN 114211224A), which includes a frame, a nail supply system is installed on the left side of the upper surface of the frame by screws, a robot is fixedly arranged near the middle of the upper surface of the frame, a riveting mechanism is also arranged on the upper end of the frame, a direct module is arranged on the upper surface of the frame, a riveting die assembly is arranged on the upper end of the direct module, and the nail supply system automatically supplies nails, which are then taken away by the robot and placed in the riveting die assembly. This technical solution adopts a nail supply system to realize automatic nail supply, and then the robot takes away and puts the riveting die assembly to realize the stapling process.

[0006] For another example, Dongguan Xinhangcheng Automation Equipment Co., Ltd. discloses an automatic riveting machine (patent publication number: CN108115073A), including a frame, a first Y-axis module and a second Y-axis module are arranged on the working table of the frame, a nail suction and feeding group is arranged inside the first Y-axis module and the second Y-axis module, and a nail pressing mechanism module is also arranged on the frame, and the nail pressing mechanism module includes a gas-liquid booster cylinder, a nail pressing feeding group, an X-axis module and a clamping nozzle. The automatic riveting machine realizes automatic feeding, has full-automatic suction and nail pressing dual functions, and realizes the stapling process.

[0007] However, although the above-mentioned prior art realizes the function of automatic stapling of the manipulator to a certain extent, it can only perform stapling of a single type of rivets and lacks versatility. If the stapling function of rivets of other specifications is to be realized, the suction nozzle of the manipulator needs to be adaptively adjusted, especially when rivets of different specifications need to be riveted on parts, riveting machines of different specifications need to be arranged in an assembly line, and after the riveting process of the corresponding specification is performed on the first riveting machine, the parts are transferred to the next process for the riveting process of another specification. This will greatly increase the complexity of the equipment, and it is impossible to achieve the flexibility and versatility of the equipment, resulting in a waste of resources and a corresponding reduction in riveting efficiency.

[0029] Please refer to Figure 1 The utility model embodiment provides a universal stapling and riveting equipment, which includes a frame 1, a stapling module, a punching module 6 and a feeding assembly line. The stapling module, the punching module 6 and the feeding assembly line are installed on the frame 1. The feeding assembly line is used to transfer the parts to be riveted to the stapling station or the punching station, so as to facilitate the stapling process at the stapling station and the punching process at the punching station to achieve the final riveting forming; the stapling module is used to load the rivet into the riveting hole of the part, and the punching module 6 is used to punch the rivet in the riveting hole of the part to achieve the riveting of the part.

[0030] The stapling module includes a multi-head manipulator 4 and a sieve plate 5, and the multi-head manipulator 4 includes at least two groups of suction heads or clamps of different specifications.

When the first multi-head manipulator completes stapling and returns to the sieve tray 5, the second multi-head manipulator performs stapling. It can be seen that the first multi-head manipulator and the second multi-head manipulator can perform stapling work alternately, which greatly improves the stapling efficiency.

[0035] In a possible embodiment, the loading line includes a mobile base 3 and a transfer platform 2 movably arranged on the mobile base, and the transfer platform 2 is used to hold the parts.
