Description

Technical Field

[0001] The present invention relates to the technical field of actuator production lines, and in particular to an assembly production line for thin-film linear pneumatic actuators. Background Art

[0002] A diaphragm linear pneumatic actuator uses air pressure to deform a diaphragm to achieve linear motion. It features a compact structure, fast response, and high control precision, making it widely used in automation control. Its core components include the diaphragm, spring, push rod, upper and lower diaphragm covers, and a bracket. Assembly requires the assembly of the actuator bracket, lower diaphragm cover, assembly, spring seat, spring, and upper diaphragm cover, as well as bolt tightening.

[0003] In the prior art, the assembly of such actuators mainly relies on manual operation, which has the following problems:

[0004] 1. The manual assembly steps are cumbersome, and the connection between each process relies on manual handling and positioning, which is time-consuming and difficult to meet the needs of large-scale production;

[0005] 2. Manual operation is easily affected by fatigue and skill level, resulting in fluctuations in product quality;

[0006] 3. Labor costs continue to rise, and manual assembly can easily cause safety hazards, further increasing management costs.

[0007] Although some automated equipment has been applied in industrial assembly, dedicated production lines for thin-film linear pneumatic actuators still have shortcomings. For example, existing production lines are mostly linear in layout, which cannot achieve closed-loop continuous production; the automated mechanisms have single functions, which makes it difficult to cover the coordinated operation of multiple processes; and there is a lack of efficient feeding and positioning solutions for precision components such as springs and nuts.

It can solve the problems in the prior art that the assembly of actuators mainly relies on manual operation, resulting in low production efficiency, large quality fluctuations and high labor costs; and the embedded nut mechanism adopted in the present invention is driven by a rotating motor to drive the circular turntable in conjunction with the pushing cylinder, which can realize the precise feeding of nuts and gaskets; the tapered end and expansion groove design of the material picking head ensure the stability of component grasping and placement, and reduce assembly errors.
