[0002] O-rings, as common sealing elements, are widely used in mechanical, hydraulic, and pneumatic fields. During assembly, the O-ring typically needs to be expanded to a certain size to fit onto the workpiece. Traditionally, this is done manually, which is difficult and inefficient.

[0003] The prior art CN116214420A discloses a sealing ring assembly tooling, which can use a self-expanding mechanism to expand the ring and a lifting mechanism to fit the ring into the workpiece. However, during the assembly process, the sealing ring picking, sliding drive mechanism, and sealing ring placement all need to be completed manually, which is a semi-automatic or manual tooling, and the production efficiency is still low. Summary of the Invention

[0008] In one embodiment of this application, the ring expanding and ring-catching mechanism includes: Several vertically arranged swing arms are distributed in a circular array; the lower end of each swing arm is hinged to the lifting plate of the moving mechanism, and the upper end is provided with an expanding claw. The rocker arm drive assembly is used to drive each rocker arm to swing inward simultaneously so that the expanding claws converge and extend into the sealing ring to be assembled; and to drive each rocker arm to swing outward simultaneously so that the sealing ring is expanded by the expanding claws. Several unloading ring components are installed one by one on the swing arm to push the enlarged sealing ring away from the expanding ring claw so that it can be fitted onto the product located inside the expanding ring claw.

[0009] In one embodiment of this application, the middle part of the swing rod is provided with an inclined guide groove; when the swing rod is vertical, the circumference diameter of the lower end of each guide groove is smaller than the circumference diameter of the upper end.

[0010] In one embodiment of this application, the ring expanding and ring-catching mechanism further includes: The product positioning seat, located inside the swing arm and below the expanding claw, is used to place the product after the expanding claw opens; and The positioning seat lifting assembly is used to adjust the height of the product positioning seat.

[0011] In one embodiment of this application, the positioning seat lifting assembly includes: The second lead screw is vertically positioned on the outside of the swing arm; The second lifting block, one end of which is mounted on the second lead screw, and the other end extending into the inside of the swing arm for use with and installation of a product positioning seat; and The second lead screw drive assembly is used to drive the second lead screw to rotate, thereby causing the second lifting block to rise and fall to adjust the height of the product positioning seat.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] This application provides a sealing ring assembly machine, which will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments of this application. Furthermore, in the following embodiments, the descriptions of each embodiment have their own emphasis; parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments.

[0024] See Figure 1 and Figure 2 In one embodiment, the sealing ring assembly machine includes: Feeding mechanism 1 is used to supply sealing rings; The moving mechanism 2 is located on one side of the feeding mechanism 1; The ring-expanding and ring-catching mechanism 3 is mounted on the moving mechanism 2; wherein... The moving mechanism 2 is used to drive the ring expanding and ring fitting mechanism 3 to move to the sealing ring outlet of the feeding mechanism 1 to pick up the material, and then drive the ring expanding and ring fitting mechanism 3 to the ring fitting position to fit the sealing ring onto the product.

[0025] In this embodiment, the feeding mechanism 1 automatically sorts and feeds the sealing rings 100, and then the moving mechanism 2 drives the ring expanding and ring fitting mechanism 3 to complete the material picking, ring expanding, and ring fitting operations in sequence. The entire process does not require manual intervention in material picking, feeding, assembly, etc., and realizes full automation of sealing ring assembly. Compared with the existing semi-automatic tooling, it further improves production efficiency and reduces the intensity of manual labor.

[0026] See Figure 10 In one embodiment, the feeding mechanism 1 includes: a vibratory feeder 11; a feeding plate 12, on which a feeding channel 121 is provided; the inlet end of the feeding channel 121 is connected to the vibratory feeder 11, and the outlet end is provided with a narrowing section 122; wherein the vibratory feeder 11 is used to transport the sealing ring to the narrowing section 122 of the feeding channel 121 to wait for the ring expanding and ring closing mechanism 3 to pick up the material.

[0027] In this embodiment, the width of the feeding channel 121 can be adapted to the outer diameter of a single sealing ring to ensure that one sealing ring passes through at a time. The narrowing portion 122 can prevent the sealing ring from falling off the outlet end of the feeding channel 121. Furthermore, a notch is provided at the bottom of the narrowing portion 122 to facilitate the expansion claw 32 of the ring expanding and purging mechanism 3 extending upwards into the sealing ring. Then, during the translational movement of the ring expanding and purging mechanism 3, the sealing ring can be carried away from the narrowing portion 122, completing the ring removal process.

[0028] See Figure 2 In one embodiment, the moving mechanism 2 includes: a lateral moving component 21, and a lifting component 22 mounted on the lateral moving component 21; the expanding and looping mechanism 3 is disposed on the lifting component 22.

[0029] In one embodiment, when the ring is being removed, the lateral moving component 21 can move the ring expanding and ring fitting mechanism 3 to below the sealing ring outlet of the feeding mechanism 1. The lifting component 22 drives the ring expanding and ring fitting mechanism 3 to rise, so that its ring expanding claw 32 extends into the sealing ring. The lateral moving component 21 drives the ring expanding and ring fitting mechanism 3 to leave, and the ring expanding claw 32 thereby moves the sealing ring out of the feeding mechanism 1 and into the subsequent ring expanding and ring fitting stage.

[0030] See Figure 2Optionally, the transverse movement assembly 21 includes: a base plate 211 on which a slide rail 212 is provided; a transverse movement plate 213 mounted on the slide rail 212; and a transverse movement driver 214 fixed on the base plate 211, with its drive rod connected to the transverse movement plate 213. The transverse movement driver 214 can be a linear cylinder, which can drive the transverse movement plate 213 to make stable transverse reciprocating movements along the slide rail 212. It has a fast action response speed and precise control, and can accurately drive the ring expanding and ring-forming mechanism 3 to move and switch between the feeding position and the ring forming position.

[0031] See Figure 2 , Figure 3 and Figure 4 In this embodiment, the lifting assembly 22 includes: a translation plate 221, disposed above the transverse plate 213; pulleys 222 are provided on both sides of the translation plate 221; a pulley groove 2131 for accommodating the pulleys 222 is provided on the upper surface of the transverse plate 213; a lifting plate 223, disposed above the transverse plate 213, for mounting the expanding ring mechanism 3; a mating block 224 supported on the corresponding pulley 222 is provided on the lower surface of the lifting plate 223; the lower surface of the mating block 224 is higher on one side and lower on the other side, and transitions through an inclined surface; and a translation driver 225, fixed on the transverse plate 213, for driving the translation plate 221 to move, so as to drive the lifting plate 223 to rise and fall through the cooperation of the pulleys 222 and the mating block 224.

[0032] In this embodiment, the lifting drive method has a simple structure. Lifting action can be achieved through translation drive, resulting in a low overall height and reduced overall equipment size. Simultaneously, the action is stable and reliable, easy to control, and allows for precise adjustment of the lifting plate 223's height to meet the height requirements of different processes during the ring expansion and ring setting. Preferably, the translation plate 221 can have a frame-like structure, and the translation driver 225 can be a linear cylinder, located inside the translation plate 221, further saving space.

[0033] See Figure 4 The bottom surface of the mating block 224 can be Z-shaped. When the pulley 222 moves to the right, the mating block 224 rises; when the pulley 222 returns to its original position to the left, the mating block 224 falls. The pulley groove 2131 can limit the movement trajectory of the pulley 222.

[0034] Optionally, the transverse plate 213 may be provided with several columns 2132, and the lifting plate 223 may be fitted onto the columns 2132 and slidably engaged, so that the lifting plate 223 can be raised and lowered stably.

[0035] Further, see Figure 5 , Figure 6In one embodiment, the ring-expanding and ring-fitting mechanism 3 includes: a plurality of vertically arranged swing rods 31 arranged in a circular array; the lower end of each swing rod 31 is hinged to the lifting plate 223 of the moving mechanism 2, and the upper end is provided with an expanding claw 32; a swing rod driving assembly 33 is used to drive each swing rod 31 to swing inward simultaneously, so that the expanding claw 32 gathers and extends into the sealing ring to be assembled; and to drive each swing rod 31 to swing outward simultaneously, so as to expand the sealing ring through the expanding claw 32; a plurality of ring-unloading assemblies 34 are correspondingly arranged on the swing rods 31, and are used to push the expanded sealing ring away from the expanding claw 32 so as to fit it onto the product located inside the expanding claw 32.

[0036] In one embodiment, there may be multiple swing arms 31, such as six, arranged in a circular array on the lifting plate 223. When retrieving the ring, the swing arms 31 are positioned as follows: Figure 5 When the sealing ring is in the converged state as shown, the expanding claw 32 is also in the converged state. During the expansion, the rocker arm drive assembly 33 drives each rocker arm 31 to swing outward simultaneously, opening the expanding claw 32 and expanding the diameter of the sealing ring. After the diameter is expanded, the product can be placed inside the sealing ring, and then the unloading assembly 34 actuates to push the sealing ring away from the expanding claw 32, thus fitting it onto the product.

[0037] Optional, see Figure 7 The expanding claw 32 includes: a claw portion 321, which is arranged vertically; and a connecting rod 322, one end of which is fixedly connected to the upper end of the swing rod 31, and the other end of which is fixedly connected to the lower end of the claw portion 321.

[0038] In some embodiments, the claw portion 321 may not be completely vertical; it may be slightly inclined inwards. This prevents the claw portion 321 from tilting outwards excessively when the sealing ring is expanded to the correct diameter, facilitating the pushing of the sealing ring from bottom to top. Optionally, the claw portion 321 and the connecting rod 322 may be integrally formed.

[0039] Furthermore, the ring unloading assembly 34 includes: a ring unloading driver 341, fixed on the corresponding swing arm 31; and a ring unloading rod 342, the outer end of which is connected to the ring unloading driver 341, and the inner end of which extends to the outer side of the lower part of the claw portion 321.

[0040] In some embodiments, the ring unloading driver 341 may be a cylinder. The upper surface of the inner end of the ring unloading rod 342 is a flat portion for supporting the sealing ring and maintaining its horizontal position.

[0041] See Figure 6For clarity, the figure conceals part of the swing arm 31 and components located inside the swing arm. As an optional implementation of the swing arm 31's oscillation, the swing arm 31 has an inclined guide groove 311 at its center; when the swing arm 31 is vertical, the circumference diameter of the lower end of each guide groove 311 is smaller than the circumference diameter of its upper end. The swing arm drive assembly 33 includes: a first lead screw 331, vertically disposed inside each swing arm 31; a first lifting block 332, mounted on the first lead screw 331; a locking block 3321 for engaging with each guide groove 311 on the first lifting block 332; and a first lead screw drive assembly 333 for driving the first lead screw 331 to rotate, thereby causing the first lifting block 332 to rise and fall, thus driving the swing arm 31 to swing inward and outward through the cooperation of the locking block 3321 and the guide groove 311.

[0042] In this embodiment, when the first lead screw drive assembly 333 drives the first lead screw 331 to rotate, the rotation of the first lead screw 331 will drive the first lifting block 332 to move vertically along the first lead screw 331. When the first lifting block 332 descends, the locking block 3321 descends synchronously. Through cooperation with the inclined guide groove 311, it squeezes each swing rod 31 to rotate outward and open simultaneously, driving the expanding claw 32 to expand outward, thereby expanding the inner diameter of the sealing ring gathered on the expanding claw 32 to meet the size requirements of the product. When the first lifting block 332 rises, the locking block 3321 rises synchronously. The pressure on the guide groove 311 changes, causing each swing rod 31 to rotate inward and retract simultaneously, allowing the expanding claw 32 to return to the gathered state so that it can be inserted into the sealing ring to be assembled next time to complete the material picking action. This driving method, which uses a lead screw to lift and drive the swing arms to swing synchronously, ensures that the swing amplitude of each swing arm is consistent. This guarantees that the sealing ring expands in a uniform manner throughout, preventing issues such as excessive local expansion that could cause deformation or damage to the sealing ring, or insufficient local expansion that would prevent it from being fitted into the product. This improves the stability and quality of the ring expansion action.

[0043] Optionally, the ring expanding and ring-attaching mechanism 3 further includes: a product positioning seat 38, which is disposed inside the swing arm 31 and below the ring expanding claw 32, for placing the product after the ring expanding claw 32 is opened; and a positioning seat lifting assembly 35, for adjusting the height of the product positioning seat 38.

[0044] In some applications, the height of the product positioning seat 38 can be pre-adjusted using the positioning seat lifting assembly 35. After the sealing ring is expanded to the correct diameter by the expanding claw 32, the lower end of the product can be placed on the product positioning seat 38 for positioning. Then, the ring removal assembly 34 removes the ring, thereby ensuring that the sealing rings are uniformly fitted on each product and improving assembly accuracy.

[0045] Optional, see Figure 8The positioning seat lifting assembly 35 includes: a second lead screw 351, which is vertically arranged; a second lifting block 352, which is fixedly connected to the lower end of the vertical support rod 381 of the product positioning seat 38 and threadedly engaged with the second lead screw 351; and a second lead screw drive assembly 353, which drives the second lead screw 351 to rotate, thereby driving the second lifting block 352 to rise and fall, thereby adjusting the height of the product positioning seat 38.

[0046] In this embodiment, the height of the product positioning seat 38 can be precisely adjusted by the second lead screw drive assembly 353 to adapt to products of different heights and sizes, improve the adaptability of the equipment, and meet the assembly requirements of products of different specifications.

[0047] Optionally, the product positioning seat 38 includes: a plurality of vertical support rods 381 disposed between two swing rods 31; the lower end of the vertical support rods 381 is fixed on the second lifting block 352; and a plurality of horizontal rods 382; the outer end of the horizontal rods 382 is fixed to the upper end of the corresponding vertical support rods 381, and the inner end extends to the lower part of the expanding claw 32 for supporting the product.

[0048] In some embodiments, the number of crossbars 382 can be three or more. The crossbars 382 cooperate to form a stable support structure, which will not interfere with the swing of the swing arm 31 or the opening and closing action of the expanding claw 32. At the same time, it can stably support products of different specifications, and the structure is simple and reliable.

[0049] Optionally, the ring-expanding and ring-jointing mechanism 3 further includes a lead screw fixing plate 36 and a guide rod 37. The upper and lower ends of the first lead screw 331 and the second lead screw 351 can be rotatably mounted on the lead screw fixing plate 36. The lead screw fixing plate 36 is fixedly connected to the lifting plate 223 via the guide rod 37, thereby ensuring the stability of the overall structure. Furthermore, see... Figure 9 The lead screw fixing plate 36 can be located between the crossbar 382 and the first lifting block 332. The upper end of the first lead screw 331 can be installed on the plate of the lead screw fixing plate 36 located inside the swing arm 31, and the upper end of the second lead screw 351 can be installed on the plate of the lead screw fixing plate 36 located outside the swing arm 31. The first lifting block 332 and the second lifting block 352 can slide with the corresponding guide rod.

[0050] Further, see Figure 1 , Figure 6 and Figure 8The lower ends of the first lead screw 331 and the second lead screw 351 both extend below the lifting plate 223 of the moving mechanism 2; the first lead screw drive assembly 333 includes a first motor 3331 mounted on the lifting plate 223, whose output shaft extends below the lifting plate 223 and is connected to the first lead screw 331 via a first transmission belt 3332; and the second lead screw drive assembly 353 includes a second motor 3531 mounted on the lifting plate 223, whose output shaft extends below the lifting plate 223 and is connected to the second lead screw 351 via a second transmission belt 3532.

[0051] In this embodiment, the layout of placing transmission components such as the transmission belt below the lifting plate 223 can make full use of the idle space below the lifting plate 223, avoid occupying the space of the swing arm 31 area above the lifting plate 223, avoid interference with components such as the swing arm and positioning seat, further optimize the overall structure of the equipment, reduce the equipment footprint, and make the overall structural layout more compact and reasonable.

[0052] Based on the above embodiments, an embodiment of the present invention also provides a working method of the above-mentioned sealing ring assembly machine, including: expanding the diameter of the sealing ring with an expanding claw; placing the product to be assembled through the expanded sealing ring on the product positioning seat below the expanding claw; the unloading assembly pushes the enlarged sealing ring away from the expanding claw to be fitted onto the product located inside the expanding claw; after the assembled product is taken out, the moving mechanism drives the expanding claw to move to the sealing ring outlet of the feeding mechanism to pick up the material, and then returns to the ring fitting position.

[0053] In some embodiments, a product detection sensor 101 electrically connected to the control module can be disposed above the expanding claw 32 to detect whether a product is placed on the product positioning seat 38. A sealing ring detection sensor 102 can be disposed at the outlet of the feeding channel 121 to detect the presence or absence of a sealing ring at the narrowing section 122. The vibratory feeder 11, the transverse drive 214, the translation drive 225, the first motor 3331, the unloading drive 341, the second motor 3531, etc., can all be electrically connected to the control module. Both the product detection sensor 101 and the sealing ring detection sensor 102 can be photoelectric sensors.

[0054] The following is an example of the working process of a sealing ring assembly machine in one application scenario; The ring-expanding and ring-fitting mechanism 3 can expand the diameter of a sealing ring at the expansion position and then wait. The product can be placed on the product positioning seat 38 manually, by a product loading / unloading robot, or by other means. After the product detection sensor 101 detects the product, the control module controls the ring-unloading driver 341 to actuate, thereby fitting the sealing ring onto the product. After the product is removed from the product positioning seat 38, the control module controls the first motor 3331 to actuate, causing the ring-expanding claw 32 to retract. The control module then controls the transverse driver 214 to actuate, moving the ring-expanding claw 32 below the outlet of the feeding channel 121. The translation driver 225 actuates, raising the ring-expanding claw 32 below the sealing ring. The transverse driver 214 resets, driving the ring-expanding and ring-fitting mechanism 3 back to the expansion position. The translation driver 225 resets, and the ring-expanding claw 32 descends. The first motor 3331 actuates, causing the ring-expanding claw 32 to open outward, thus expanding the diameter of the sealing ring, awaiting the product to be placed into the product positioning seat 38.

[0055] In summary, this sealing ring assembly machine, through the coordination of the feeding mechanism, the moving mechanism, and the ring expanding and fitting mechanism, achieves fully automated assembly of sealing rings from sorting and feeding to complete fitting into the product, eliminating the need for manual intervention, significantly improving assembly efficiency and reducing labor costs. Simultaneously, the screw-linked swing arm ring expanding structure ensures uniform ring diameter expansion. The adjustable-height product positioning seat adapts to different product specifications. The overall structure is compact, with high space utilization, stable and reliable operation, and can meet the automated assembly needs of various sealing ring specifications.
