Description

Technical Field

[0002] In the rapidly developing modern automobile industry, the air valve pump is the core component of the automobile air suspension system. Its performance and assembly accuracy are directly related to the vehicle's handling stability and ride comfort. However, in the assembly process of the air valve pump, the valve core feeding link has always been a key step that needs to be improved. The traditional feeding method mainly relies on manual or semi-automatic mechanical means. Although these methods meet production needs to a certain extent, they inevitably expose their inherent limitations.

[0003] Although the manual feeding method is flexible, it is limited by human physical strength and concentration, which often leads to low feeding efficiency. Long working hours significantly increase labor intensity and make it difficult to ensure assembly accuracy. With the increasing maturity of automation technology, semi-automatic feeding mechanisms have gradually replaced traditional manual feeding methods and become an important part of modern production lines. However, although the existing semi-automatic feeding mechanisms, such as robotic arms and conveyor belts, have improved feeding efficiency to a certain extent, they face many challenges in actual operation. When these mechanisms are transmitting valve cores, they often suffer from mechanical vibration or insufficient transmission accuracy, which leads to the inability to fully guarantee the stability of the valve core during the transmission process, thereby affecting the subsequent assembly accuracy. In addition, for valve cores of different specifications and shapes, these mechanisms usually need to replace or adjust the transmission components, which not only increases the complexity of operation, but also significantly increases maintenance costs.

[0051] In the above-described scheme, two groups of double-axis cylinders 607 are symmetrically installed at the front ends of both sides of the rectangular support frame 604. When the piston rods of the double-axis cylinders 607 extend forward, they will push the movable plate 608 to move toward the middle, thereby causing the round-headed positioning pins 609 fixedly installed at both ends of the movable plate 608 to move toward each other, wherein the round-headed positioning pins 609 are adapted to the positioning holes 12 opened on the side walls of the valve core tray 4.

[0054] Furthermore, when the valve core tray 4 is unloaded from the first multiple chain conveyor line 2, the valve core tray 4 will automatically enter the feed port of the rectangular support frame 604. At this time, after the position sensor 605 arranged behind the rectangular support frame 604 detects that the valve core tray 4 is in place, the double-axis cylinder 607 starts to work, pushing the movable plate 608 to move to the middle, so that the round-headed positioning pin 609 is inserted into the positioning hole 12 of the valve core tray 4; at the same time, the first magnetically coupled rodless cylinder 601 starts to work, driving the rectangular support frame 604 to translate along the limiting guide rail 18, thereby moving the valve core tray 4 to the top of the predetermined transfer platform 7. After reaching the predetermined position, the piston rod of the double-axis cylinder 607 retracts, thereby driving the round-headed positioning pin 609 to withdraw from the positioning hole 12, so that the valve core tray 4 is taken away by the transfer platform 7 and the next step is carried out. The entire translation assembly 6 realizes the smooth and precise movement of the valve core tray 4 from the first multiple chain conveyor line 2 to the transfer platform 7 through precise control and layout.
