Fully automated assembly is achieved, saving labor costs.

[0035] The present invention achieves a high degree of automation. From the assembly jig that is circulated on the circular conveyor line, to the precise operation of each assembly mechanism (including end cover assembly and metal locking claw assembly), to the flexible scheduling of the push assembly components, no direct human involvement is required, which greatly reduces the labor cost, avoids the assembly errors caused by human factors, and improves the operation efficiency of the entire production line.

The unloading mechanism is responsible for the orderly output of the finished products, avoiding the backlog and damage of the finished products on the production line, and ensuring the quality of the final finished products. Through the characteristics of high efficiency, precision, flexibility and intelligence, the present invention significantly improves production efficiency and product quality, reduces production costs and maintenance difficulties.

[0037] The automatic assembly method of mechanical mechanism significantly improves production efficiency and assembly accuracy through the highly integrated automatic assembly line design. First, the shell loading step realizes continuous and stable material supply. In the metal belt assembly stage, the precise assembly positioning part is matched with the rectangular groove and round hole on the metal belt to ensure the accuracy and stability of the metal belt installation and reduce the error caused by manual operation. At the same time, the parallel end cap assembly process realizes the rapid and efficient assembly of the end cap and the metal lock claw through the coordinated operation of the ring conveyor line and a variety of automatic mechanisms, and cleverly uses the push assembly mechanism to ensure that the metal lock claw is accurately embedded in the end cap, which enhances the structural strength and sealing of the product. The end cap assembly link further consolidates the connection between the metal belt and the shell through precise grasping and pressing fixation, and improves the stability of the overall assembly. The application of ultrasonic welding and hot melt riveting technology not only realizes the firm combination of the end cap and the assembly groove, but also covers the outer edge of the protrusion by hot melt, which enhances the appearance and durability of the product. At the same time, the design of hot melt fixing of the metal belt further improves the reliability of assembly and ensures the stability and safety of the product during long-term use. The present invention significantly improves the assembly efficiency and product quality of mechanical mechanisms through its high efficiency, precision and stability.

[0066] This embodiment achieves a high degree of automation. From the assembly jig 9 that is circulated on the ring conveyor line 1, to the precise operation of each assembly mechanism (including end cover assembly and metal locking claw assembly), to the flexible scheduling of the push assembly component 11, no direct human involvement is required, which greatly reduces the labor cost, avoids the assembly error caused by human factors, and improves the operation efficiency of the entire production line.

A method for automatic assembly of a mechanical mechanism, characterized in that: An automated mechanical structure assembly line comprising any one of claims 1 to 8; The automatic assembly method comprises the following steps: Step S1, shell loading: placing the shell on the assembly transfer line for conveying, and the assembly transfer line drives the shell to pass through the metal belt assembly mechanism, the ring conveyor line, the ultrasonic welding mechanism, the hot melt mechanism and the unloading mechanism in sequence; Step S2, metal belt assembly: the assembly transfer line conveys the shell to one side of the metal belt assembly mechanism, the metal belt assembly mechanism is used to grab the metal belt and place it on the assembly positioning part, the metal belt is provided with a rectangular groove and a round hole, the assembly positioning part is provided with a positioning pin and a rectangular positioning block, so as to directional assemble the rectangular groove and the round hole of the metal belt, and the rectangular positioning block is located in the assembly groove; Step S3, end cap assembly: while performing step S2, the annular conveyor line drives the assembly jig to circulate, the end cap is assembled to the first fixing groove by the end cap assembly mechanism, the metal locking claw is grabbed and assembled to the second fixing groove by the metal locking claw assembly mechanism, and then the assembly jig is transported to the push assembly mechanism under the action of the annular conveyor line, the metal locking claw is pushed from the second fixing groove to the first fixing groove by the push assembly mechanism, and is installed into the end cap through the guidance of the assembly slide groove; Step S4, end cap assembly: the annular conveyor line transfers the assembly jig with the assembled end cap to the side close to the assembly transfer line, and the end cap picking assembly is used to grab the end cap on the assembly jig and assemble it into the assembly groove, and one end of the metal strip is pressed and fixed by the end cap; Step S5, ultrasonic welding: the assembly transfer line transports the shell of the assembled end cap toward the ultrasonic welding mechanism, and the end cap is welded and fixed on the assembly groove by the ultrasonic welding mechanism; Step S6, hot melt riveting: the assembly transfer line transports the ultrasonically welded shell toward the hot melt mechanism, hot melts the raised outer edge to cover the end cover on the assembly groove, and hot melts the assembly positioning part to fix the metal strip. After the hot melt riveting is completed, the material is unloaded through the unloading mechanism.
