Description

[Technical field]

[0001] The invention relates to an assembling device and an assembling method for assembling a pipe fitting and a threaded sleeve. [Background technology]

[0002] The rods of photographic equipment usually include selfie sticks, tripod support rods, etc. In order to facilitate storage, carrying, adjustment and use, the rods of photographic equipment usually include pipes and screw sleeves connected to the corresponding end positions of the pipes to limit the telescopic adjustment of the inner pipe.

[0003] At present, the assembly of photographic equipment rods is generally done by manually applying glue to the corresponding ends of the pipes, and then the workers connect the screw sleeves to the corresponding ends of the pipes coated with glue. However, the manual assembly method increases the labor intensity, prolongs the working time, slows down the assembly speed of photographic equipment rods, reduces the production efficiency of photographic equipment rods, and the quality of the assembled products cannot be guaranteed.

[0004] In addition, today's pipe fittings are usually made of aluminum, carbon fiber, etc. It is difficult to evenly apply glue to the corresponding ends of the pipe fittings by manual coating; and in some low-temperature environments, the glue is prone to solidification, resulting in poor coating effect.

[0005] In addition, due to the presence of irritating odors, manual application of glue will have an adverse impact on the health and safety of workers.

[0006] Therefore, the present invention is studied and proposed in view of the above problems. [Summary of the invention]

[0060] The synchronous transport mechanism 8 transports the single pipe 100 of the pipe feeding mechanism 1 to the pipe rotation positioning device 2 for positioning. If the temperature sensor detects that the glue temperature is lower than the preset value, the glue heating device 31 starts to work to preheat the glue. If the temperature sensor detects that the glue temperature is higher than the preset value, the glue heating device 31 does not work. Then the pipe rotation positioning device 2 drives the pipe 100 to rotate accordingly and cooperates with the pipe glue coating mechanism 3 to coat at least one circle of glue on the corresponding end of the pipe 100. The synchronous transport mechanism 8 transports the pipe 100 coated with glue on the pipe rotation positioning device 2. 0 is transported to the pipe fitting rotation positioning mechanism 4 for positioning; at the same time, after the screw sleeve flip assembly mechanism 6 receives a single screw sleeve 110 from the screw sleeve supply mechanism 5, the screw sleeve 110 is flipped 90° to a preset position so that the screw sleeve 110 port is aligned with the corresponding end of the pipe fitting 100 on the pipe fitting rotation positioning mechanism 4, and then the pipe fitting rotation positioning mechanism 4 drives the pipe fitting 100 to rotate accordingly so that the screw sleeve 110 is threadedly connected to the end of the pipe fitting 100 coated with glue; the synchronous transport mechanism 8 transports the pipe fitting 100 on the pipe fitting rotation positioning mechanism 4 to complete the assembly of the screw sleeve 110 to the pipe fitting storage mechanism 7 for storage.
