Description

Technical Field

[0001] The utility model relates to the technical field of sealing ring assembly equipment, in particular to an alternating transfer table of a sealing ring assembly machine. Background Art

[0002] Among the sealing rings, O-rings are the most commonly used. O-rings are the most widely used seals on various mechanical equipment. They have an extremely simple cross-sectional structure and are self-sealing with reliable sealing performance. They are mainly used for static sealing and reciprocating motion sealing.

[0003] In order to improve the sealing effect of the workpiece, it is necessary to insert the O-ring into the groove of the workpiece. During installation, the O-ring should be expanded and passed over any end of the workpiece before being inserted into the groove. As the shape of the workpiece becomes smaller and smaller, the size of the O-ring is also getting smaller and smaller, which brings great inconvenience to the installation work. The traditional assembly of O-rings generally relies on manual assembly, resulting in a high rate of product failure, limited assembly efficiency, time-consuming and labor-intensive, and greatly increased production costs. At the same time, due to the low assembly speed of manual operation, it is difficult to adapt to the needs of automated assembly and the needs of fierce market competition.

[0004] Therefore, an automatic assembly device for O-rings was later developed, which can realize the automation of O-ring assembly. For example, an automatic assembly device for O-rings disclosed in a Chinese patent document with the announcement number CN103317336B includes an upper ring support module and a ring transfer and ring removal module; the upper ring support module forms a feeding station and a ring support station; when the O-ring feeding device is in the feeding station, the O-ring feeding device transfers the O-ring to the O-ring feeding device; the feeding needle cylinder drives the O-ring feeding device to move to the ring support station, and the ring support device performs a ring support action on the O-ring, and the ring support device transfers the O-ring to the ring transfer and ring removal module, and the ring transfer and ring removal module transfers the enlarged O-ring from the ring support station to the ring removal station, and separates from the enlarged O-ring so that it is sleeved in the groove of the workpiece to be assembled, thereby realizing the automatic assembly of the workpiece and the O-ring. It can realize the automation of O-ring assembly, greatly improve product qualification rate and assembly efficiency, reduce labor intensity and reduce production costs.

[0005] Another example is a double seal ring assembly line and working method for inner and outer nested parts disclosed in the Chinese patent document with announcement number CN114770101A, which includes an inner insert feeding unit, an inner insert detection unit, an inner seal ring feeding assembly unit, an outer set feeding unit, an outer seal ring feeding assembly unit, an inner and outer parts assembly unit, an unqualified rejection unit, a qualified product unloading unit, a set of workpiece fixing seats, a divider, a rotating working platform, a machine table and a chassis, wherein the rotating working platform drives the workpiece fixing seat to pass through the inner insert feeding unit, the inner insert detection unit, the inner seal ring feeding assembly unit, the outer seal ring feeding assembly unit, the outer set feeding unit, and the inner and outer parts assembly unit. The double seal ring assembly line for inner and outer nested parts realizes the automatic assembly of four components by passing through each station during the rotation of the rotating working platform, focusing on the assembly of the inner and outer double seal rings, greatly improving the product qualification rate and assembly efficiency, and reducing labor intensity, labor, and production costs.

[0006] There are problems to be improved: For the feeding of the corresponding sealing ring, the existing technology feeds the material through the vibration plate, and then the pneumatic clamp directly opens and grabs the sealing ring, which leads to a slow loading speed and affects the feeding speed.

In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0038] An alternate transfer table of a sealing ring assembly machine of this embodiment, such as Figures 1 to 7 As shown, it includes a transfer support 21, the two ends of the transfer support 21 are used as a material preparation station 211 and a material retrieving station 212, and two first slide rails 213 and two second slide rails 214 are arranged in parallel and staggered in height between the material preparation station 211 and the material retrieving station 212. The first slide rail 213 and the second slide rail 214 are respectively provided with a loading module 22, and the transfer support 21 is provided with an alternating shift driving module 26, which is used to drive the loading modules 22 on the first slide rail 213 and the second slide rail 214 to alternately switch between the material preparation station 211 and the material retrieving station 212.

[0039] Specifically, the alternating shift drive module 26 includes an alternating transmission belt 261, an alternating transmission pulley 262 and an alternating drive motor 263. The alternating transmission belt 261 is elliptical and is installed on the transfer support 21 via the alternating transmission pulley 262. The alternating drive motor 263 is used to drive the alternating transmission pulley 262 to rotate. The loading module 22 of the first slide rail 213 and the loading module 22 of the second slide rail 214 are respectively fixedly connected to two sections of the alternating transmission belt 261 with opposite movement directions, so that the two groups of loading modules 22 synchronously move alternately in the material preparation station 211 and the material collection station 212. At the material preparation station 211, the peripheral mechanical arm moves multiple sealing rings to the loading module 22; at the material collection station 212, the peripheral mechanical arm takes out multiple sealing rings on the loading module 22 for the next step of assembly.

[0040] In this embodiment, each group of loading modules 22 includes a loading base plate 221 and a ring plate 222, and the ring plate 222 is mounted on the loading base plate 221.

[0046] Specifically, the follower slide 215 includes a low section 2151, a transition section 2152 and a high section 2153. The two high sections 2153 correspond to the material preparation station 211 and the material picking station 212.
