Description

Technical Field

[0001] The utility model relates to the technical field of sealing ring assembly equipment, in particular to a transplanting and assembling device for an O-shaped sealing ring. 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.

[0007] Furthermore, the existing robotic arms for grabbing sealing rings for assembly can only grab one sealing ring at a time, and the reciprocating material picking and assembly take up a lot of space, resulting in a long assembly time for a single sealing ring, which affects production efficiency.

[0049] The following will be combined with the accompanying drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0050] A transplanting and assembling device of an O-ring in this embodiment, such as Figures 1 to 13 As shown, it includes a workbench 1, and the following components are arranged on the workbench 1: an alternating transfer table 2 for preparing sealing rings, a product conveying line 4 for circulating sealing ring products to be assembled, and a robot 3 for transferring the sealing rings on the alternating transfer table 2 and assembling them onto the products on the product conveying line 4.

[0051] The alternating transfer table 2 is located beside the product conveyor line 4, and includes a transfer support 21. The two ends of the transfer support 21 (towards the direction away from the product conveyor line 4) are respectively used as a material preparation station 211 and a material collection station 212. 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 collection station 212. The first slide rail 213 is higher than the second slide rail 214. 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 collection station 212.

[0052] 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 the upper and lower 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, a manual or peripheral robot arm moves multiple sealing rings to the loading module 22; at the material collection station 212, the robot 3 takes out multiple sealing rings on the loading module 22 and performs the next step of assembly.

[0053] 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. A plurality of ring columns 223 arranged in an array are arranged on the top of the ring plate 222, and a plurality of rod placement grooves 224 are opened around the outer wall of the ring column 223 in the circumferential direction, and a plurality of ring expansion grooves 225 are opened on the side of the ring column 223 and penetrate the rod placement grooves 224 one by one. When in use, the sealing ring is sleeved outside the ring column 223, and the ring expansion rod 3223 of the manipulator 3 is inserted into the rod placement groove 224, and then moved toward the ring expansion groove 225, so that the sealing ring can be expanded and separated from the ring column 223 and taken out.

[0054] Specifically, the ring column 223 includes an introduction cone section 2231 and a clamping ring straight section 2232 arranged up and down. The introduction cone section 2231 is small at the top and large at the bottom, and is used to introduce the sealing ring. The outer diameter of the clamping ring straight section 2232 matches the inner diameter of the sealing ring, and the sealing ring tightens the clamping ring straight section 2232 with an interference fit.

[0055] In this embodiment, the number of the ring-carrying plates 222 on each group of the loading bottom plate 221 is two, and the loading bottom plate 221 is provided with an auxiliary guide rail 226, and the two ring-carrying plates 222 are slidably mounted on the auxiliary guide rail 226, and a compression spring 227 is provided between the two ring-carrying plates 222 to keep a preset distance from each other. The material-retrieving station 212 is provided with a close-up driving member 27, which is used to overcome the force of the compression spring 227 and drive the two ring-carrying plates 222 on the loading bottom plate 221 to approach each other. At the material preparation station 211, the two ring-carrying plates 222 of the loading module 22 are far away from each other, so that a certain distance is maintained so that there is a large space around the ring-carrying plates 222, which is convenient for different robotic arms to load sealing rings on different ring-carrying plates 222 respectively. At the material-retrieving station 212, the two ring-carrying plates 222 are close to each other or even spliced ​​together, which is convenient for the robotic arm to take away the sealing rings on the two ring-carrying plates 222 at the same time. The approaching drive member 27 in this embodiment adopts a cylinder structure, which can be changed to other linear drive modules in practice, or it can be changed to a drive member set on the loading bottom plate 221, as long as it can drive the ring plate 222 to move along the auxiliary guide rail 226.

[0056] In this embodiment, the two groups of loading modules 22 are at the same height at the material preparation station 211 and the material taking station 212, and the loading modules 22 on the first slide rail 213 and the loading modules 22 on the second slide rail 214 can longitudinally avoid each other when shifting. The first slide rail 213 is higher than the second slide rail 214, and the loading bottom plate 221 of the loading module 22 located on the first slide rail 213 is slidably arranged on the first slide rail 213 via a slide seat; the second slide rail 214 is slidably provided with an auxiliary plate 23 via a slide seat, and the loading bottom plate 221 of the loading module 22 located on the second slide rail 214 is installed on the auxiliary plate 23 in a liftable manner.

[0057] Specifically, the auxiliary plate 23 is provided with a directional guide hole 231, and the loading bottom plate 221 of the loading module 22 on the auxiliary plate 23 is provided with a directional guide column 2211, which can slide up and down through the directional guide hole 231 to provide stable guidance for the lifting of the loading module 22 on the auxiliary plate 23.

[0058] Specifically, the transfer support 21 is provided with a follower slide groove 215 with a height difference, and the loading bottom plate 221 of the loading module 22 on the auxiliary plate 23 is provided with an extension seat 24, and the extension seat 24 is provided with a follower roller 25 that rolls in the follower slide groove 215, so that the loading module 22 on the auxiliary plate 23 changes with the height change of the follower slide groove 215.

[0059] 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. When the loading module 22 of the second slide rail 214 is located at the high sections 2153 at both ends, the heights are the same and are higher than the loading module 22 on the first slide rail 213. The transition section 2152 is obliquely connected between the high section 2153 and the low section 2151; when the loading module 22 of the second slide rail 214 is located at the low section 2151, its height is less than the loading module 22 on the first slide rail 213, thereby achieving avoidance.

[0060] The robot 3 is located above the product conveyor line 4, and includes a support frame 31, and a pick-and-place ring module 32 and a longitudinal and transverse driving mechanism 33 arranged on the support frame 31.

The ring-unloading plate 3231 is provided with a plurality of ring-unloading holes 32311 for inserting the ring-expanding rods 3223 of a plurality of pneumatic jaws 322. When the plurality of ring-expanding rods 3223 of each pneumatic jaw 322 are away from each other, the ring-expanding rods 3223 abut against the inner wall of the ring-unloading hole 32311; the ring-unloading driving member 3232 can drive the ring-unloading plate 3231 to move in a straight line, so that the sealing rings clamped by the plurality of pneumatic jaws 322 are simultaneously pushed out of the ring-expanding rod 3223 by the ring-unloading plate 3231. Specifically, the knockout driving member 3232 is a knockout cylinder, a cylinder barrel of the knockout cylinder is fixed to the bearing plate 321 , and a piston rod of the knockout cylinder is fixed to the knockout plate 3231 .
