[0045] like Figure 1-Figure 9As shown, the O-ring installation device (hereinafter referred to as "device") provided in this embodiment includes a bracket 1, a workpiece grabbing mechanism 2 and an O-ring grabbing mechanism 3. The bracket 1 is provided with a material holding assembly 11, on which a plurality of O-rings 5 ​​are placed; the workpiece grabbing mechanism 2 is connected to the bracket 1 and is arranged above the material holding assembly 11, and the workpiece grabbing mechanism 2 can clamp and drive the workpiece 6 to move; the O-ring grabbing mechanism 3 is arranged above the material holding assembly 11 and below the workpiece grabbing mechanism 2, and the O-ring grabbing mechanism 3 includes a rotating assembly 31 and a grabbing assembly 32 for grabbing the O-ring 5, one side of the rotating assembly 31 is connected to the bracket 1, and the other side is connected to the grabbing assembly 32, and the rotating assembly 31 can drive the grabbing assembly 32 to rotate in a vertical plane, so that the grabbing assembly 32 rotates and moves the O-ring 5 on the material holding assembly 11 to the right below the workpiece 6, and can sleeve the O-ring 5 on the workpiece 6.

[0046] The device integrates the workpiece grasping mechanism 2 and the O-ring grasping mechanism 3 on the bracket 1 so that the O-ring 5 can be sleeved on the workpiece 6. The bracket 1 is provided with a material holding assembly 11, which includes a storage part and a conveying part. Several O-rings 5 ​​are placed in the storage part. One end of the conveying part is connected to the storage part, and the other end extends to the bottom of the O-ring grasping mechanism 3. When the O-ring 5 needs to be sleeved, the conveying part can sequentially transport several O-rings 5 ​​in the storage part to the position where the O-ring grasping mechanism 3 can grasp them, so that the O-ring 5 can be sleeved on the workpiece 6. In view of the fact that the material holding assembly 11 is an existing structure, its specific structural composition and principle will not be described in detail here.

[0047] In the vertical direction, the workpiece grasping mechanism 2, the O-ring grasping mechanism 3 and the material holding assembly 11 are arranged in sequence from top to bottom, and the O-ring grasping mechanism 3 plays a transmission role in changing the spatial position of the O-ring 5. The O-ring grasping mechanism 3 includes a rotating assembly 31 and a grasping assembly 32, and the grasping assembly 32 can grasp the O-ring 5, and driven by the rotating assembly 31, the O-ring 5 is rotated from the bottom of the grasping assembly 32 to the top of the grasping assembly 32. Since the O-ring grabbing mechanism 3 has no horizontal displacement, the movement of the O-ring 5 is realized only by rotating in the vertical plane, which can reduce the positioning difficulty of the workpiece grabbing mechanism 2, and avoid the increase in the positioning difficulty between the two caused by the O-ring grabbing mechanism 3 and the workpiece positioning mechanism 2 both including horizontal displacement, so that the workpiece 6 grabbed by the workpiece grabbing mechanism 2 can be more easily positioned directly above the rotated O-ring 5, and the workpiece 6 is driven by the workpiece grabbing mechanism 2 to penetrate into the O-ring 5, and driven by the O-ring grabbing mechanism 3 to make the O-ring 5 detach from the grabbing assembly 32 and then sleeved on the workpiece 6, thereby improving the assembly efficiency and assembly quality of the O-ring 5. The device can reduce the need for horizontal movement during the assembly process of the O-ring 5, reduce the difficulty of the alignment of the O-ring 5 and the workpiece 6, and thus improve the assembly efficiency and assembly quality of the O-ring 5 and the workpiece 6.

[0048] Preferably, the bracket 1 is a frame structure, and the bracket 1 includes a plurality of pillars. The workpiece grasping mechanism 2 and the O-ring grasping mechanism 3 can be arranged on the same pillar or on different pillars, and the relative positions of the two can realize the O-ring 5 being sleeved on the workpiece 6. The bottom of the bracket 1 is provided with a support foot so that the device can remain stable during operation and play a role in buffering and absorbing vibration.

[0049] Continue to refer to Figure 1-Figure 9 Optionally, the rotating assembly 31 includes a rotating cylinder 311, a fixed end of the rotating cylinder 311 is connected to the bracket 1, and a movable end of the rotating cylinder 311 is connected to the grabbing assembly 32, so that the grabbing assembly 32 can rotate in a vertical plane relative to the bracket 1.

[0050] Driven by the rotary cylinder 311 , the grabbing assembly 32 can realize 180° rotation in the vertical plane, so that the grabbing assembly 32 can rotate between two upper and lower positions in the vertical direction, thereby grabbing the O-ring 5 on the material holding assembly 11 to the bottom of the workpiece grabbing mechanism 2 .

[0051] Optionally, the fixed end of the rotating cylinder 311 is connected to the bracket 1 through the first lifting cylinder 312 to drive the grabbing assembly 32 to move in the vertical direction.

[0052] The provision of the first lifting cylinder 312 enables the rotating cylinder 311 to move up and down in a vertical plane, so that it can be used for material holding components 11 and workpiece grasping mechanisms 2 at different heights, thereby improving the applicability of the device.

[0053] Optionally, the grabbing assembly 32 includes a first clamping cylinder 321 and a plurality of first clamping jaws 322, the fixed end of the first clamping cylinder 321 is arranged on the movable end of the rotating cylinder 311, the movable end of the first clamping cylinder 321 is connected to the plurality of first clamping jaws 322, and the O-ring 5 is stretched open by the plurality of first clamping jaws 322 to drive the O-ring 5 to move.

[0054] Driven by the first clamping jaw cylinder 321, the plurality of first clamping jaws 322 can move closer to or farther from each other, so as to change the size of the space enclosed by different first clamping jaws 322, thereby being able to open the O-ring 5 or detach the O-ring 5 from the first clamping jaws 322. Preferably, the movable end of the first clamping jaw cylinder 321 is connected with four first clamping jaws 322. The O-ring 5 is elastic, and when in use, the four first clamping jaws 322 can be contracted first, and after being inserted into the middle circular hole of the O-ring 5, the four first clamping jaws 322 can be opened, so that the O-ring 5 is sleeved on the outer wall of the first clamping jaw 322.

[0055] Optionally, a limiting groove is provided on the first clamping jaw 322 so that the O-ring 5 can be clamped in the limiting groove when the first clamping jaw 322 opens the O-ring 5 .

[0056] Preferably, the limiting groove is a concave structure provided on the outer side wall of the first clamping jaw 322, which can make the O-ring 5 receive a certain clamping effect at the limiting groove, and can also increase the friction between the O-ring 5 and the first clamping jaw 322, so as to prevent the O-ring 5 from accidentally slipping off the first clamping jaw 322, thereby affecting the sleeve efficiency and assembly quality. It is understandable that a groove can also be provided on the workpiece 6, so as to facilitate the positioning and sleeve of the O-ring 5 on the workpiece 6, thereby improving the sleeve quality of the O-ring 5.

[0057] Optionally, the grabbing assembly 32 also includes a unloading cylinder 323, a guide member 324 and a unloading member 325. The fixed end of the unloading cylinder 323 is connected to the movable end of the rotating cylinder 311, the movable end of the unloading cylinder 323 is connected to one end of the guide member 324, and the other end of the guide member 324 is connected to the unloading member 325. The unloading member 325 is sleeved on the outer periphery of the first clamp 322, so that the O-ring 5 can be separated from the first clamp 322.

[0058] Preferably, both ends of the guide member 324 are fixedly connected; the middle part of the discharge member 325 is provided with a through hole that matches the outer periphery of the first clamping jaw 322. The telescopic end of the discharge cylinder 323 drives the guide member 324 to move, so that the discharge member 325 at the other end of the guide member 324 can move up and down along the axis direction of the first clamping jaw cylinder 321, thereby pushing the O-ring 5 sleeved on the outer wall of the first clamping jaw 322 to come out, so that the O-ring 5 is transferred from the first clamping jaw 322 to the workpiece 6. Further, the O-ring 5 is pushed into the groove of the workpiece 6, so that the O-ring 5 is reliably sleeved on the workpiece 6. Specifically, the guide member 324 is a rod-shaped structure; the discharge member 325 is a plate-shaped structure.

[0059] Optionally, the grabbing assembly 32 also includes a first connecting member 326 and a linear bearing 327. The first connecting member 326 is L-shaped or T-shaped. A unloading cylinder 323 is provided at one end of the first connecting member 326 and is connected to the movable end of the rotating cylinder 311. A guide hole is provided at the other end of the first connecting member 326 and is connected to the fixed end of the first clamping cylinder 321. A linear bearing 327 is sleeved in the guide hole, and the guide member 324 is passed through the linear bearing 327.

[0060] The fixed end of the discharge cylinder 323 can be fixedly connected to one end of the first connecting member 326 close to the rotating cylinder 311, and the movable end of the discharge cylinder 323 can be inserted into the guide hole at the other end of the first connecting member 326 to drive the guide member 324 to move up and down along the axis direction of the first clamping cylinder 321. Preferably, the movable end of the discharge cylinder 323 is connected with a transition piece, and the side of the transition piece away from the discharge cylinder 323 is connected to the guide member 324. Specifically, two guide members 324 can be provided, and the two guide members 324 are respectively connected to the two ends of the transition piece, and guide holes are provided at both ends of the first connecting member 326, so that the guide members 324 can be separately provided on both sides of the first clamping cylinder 321, and then both ends of the discharge member 325 can be guided and driven, thereby improving the reliability when pushing the O-ring 5. A linear bearing 327 is provided in the guide hole, so that the guide member 324 cooperates with the linear bearing 327, which can reduce friction and improve reliability.

[0061] Understandably, Figure 1-Figure 3 The O-ring grabbing mechanism 3 in the figure is a simulated state in two working positions. When the device is actually used, the grabbing assembly 32 can only be Figure 4 and Figure 5 As shown, it is located on one side close to the material holding component 11, or as shown Figure 7 The side shown is close to the workpiece gripping mechanism 2, which is one of the two position states.

[0062] Optionally, the workpiece grasping mechanism 2 includes a second clamping cylinder 21 and a plurality of second clamping jaws 22, the fixed end of the second clamping cylinder 21 is connected to the bracket 1, and the movable end of the second clamping cylinder 21 is connected to the plurality of second clamping jaws 22 to drive the plurality of second clamping jaws 22 to clamp the workpiece 6.

[0063] Optionally, the workpiece grasping mechanism 2 further includes a second lifting cylinder 23 , and the second clamping jaw cylinder 21 is connected to the bracket 1 via the second lifting cylinder 23 , so as to be able to drive the workpiece 6 to move in the vertical direction.

[0064] Optionally, the workpiece grasping mechanism 2 further includes a transverse servo motor 24, and an output end of the transverse servo motor 24 is connected to the second lifting cylinder 23 to drive the second lifting cylinder 23 to move in a horizontal plane.

[0065] When the workpiece grasping mechanism 2 is in use, the second lifting cylinder 23 can be driven by the transverse servo motor 24 to realize horizontal movement, and the second lifting cylinder 23 can be driven by the second clamping jaw cylinder 21 to realize vertical movement, so that the second clamping jaw 22 can realize the clamping of the workpiece 6 and make the workpiece 6 match with the O-ring 5 opened by the first clamping jaw 322. After the workpiece 6 and the O-ring 5 are moved to the matching position, that is, when the workpiece 6 is located in the conical space surrounded by the O-rings 5 ​​opened by the first clamping jaws 322, the relative positions of the two are fixed, and the O-ring 5 is pushed from the first clamping jaw 322 to the groove of the workpiece 6 by the unloading member 325, so as to achieve the purpose of sleeve-mounting the O-ring 5 on the workpiece 6. Preferably, the second clamping jaw cylinder 21 can be connected to the second lifting cylinder 23 through the second connecting member 25. Specifically, the second connecting member 25 can be an L-shaped connecting plate or a T-shaped connecting plate, or other connecting structures that can realize the connection function and avoid interference. It is understandable that the storage position of the workpiece 6 is set at a position where the workpiece grasping mechanism 2 can grasp it; a plurality of workpiece grasping mechanisms 2 can be provided to improve the installation efficiency of the O-ring 5.

[0066] Continue to refer to Figure 1-Figure 9 Optionally, the device also includes an O-ring positioning mechanism 4, the O-ring positioning mechanism 4 includes a sliding assembly 41, the sliding assembly 41 includes a fixing member 411 and a sliding member 412, the fixing member 411 is arranged at one end of the material holding assembly 11 close to the O-ring grasping mechanism 3, so as to be able to receive the O-ring 5 transmitted by the material holding assembly 11, the sliding member 412 is slidably connected to the fixing member 411, and the sliding member 412 can drive the O-ring 5 to move to the bottom of the O-ring grasping mechanism 3.

[0067] Preferably, the sliding assembly 41 can be a sliding cylinder. The fixing member 411 can be fixedly arranged on the bracket 1 to maintain the stability of the sliding assembly 41. The fixing member 411 can be arranged at a preset height, so as to reduce the height difference when the O-ring 5 falls onto the sliding member 412, and avoid the posture of the O-ring 5 from being greatly offset due to the fall. The sliding member 412 includes at least two sliding positions, one of which is located at the end of the conveying part of the material holding assembly 11 away from one end of the storage part, so as to be able to receive the O-ring 5 conveyed by the conveying part; the other sliding position is located directly below the O-ring grabbing mechanism 3, so that the O-ring 5 can be placed directly below the grabbing assembly 32, so that the grabbing assembly 32 can grab the O-ring 5 from the sliding member 412. Specifically, the sliding assembly 41 can also include a limiter to make the sliding of the sliding member 412 stable and reliable.

[0068] Optionally, a positioning groove 4121 is provided on the sliding member 412 , and a supporting structure 4122 is provided on the positioning groove 4121 , so that the O-ring 5 can be mounted on the positioning groove 4121 , and the first clamping jaw 322 can extend into the positioning groove 4121 to open and grab the O-ring 5 .

[0069] The shape of the positioning groove 4121 is adapted to the shape of the O-ring 5, so that after the O-ring 5 falls onto the sliding member 412, it can cooperate with the positioning groove 4121. The supporting structure 4122 is a supporting frame or a supporting rod, which is used to prevent the O-ring 5 from passing through the positioning groove 4121 and falling, and plays a role in supporting the O-ring 5. When the O-ring 5 falls onto the positioning groove 4121, the first clamping jaw 322 can first pass through the positioning groove 4121 by contraction, and then open the first clamping jaw 322 after passing through the positioning groove 4121, so that the O-ring 5 is sleeved on the first clamping jaw 322 and moves in the vertical direction to take the O-ring 5 away from the sliding member 412, that is, the O-ring 5 is transferred from the O-ring positioning mechanism 4 to the O-ring grabbing mechanism 3. Preferably, the positioning groove 4121 is a through groove. It should be noted that the size of the positioning groove 4121 is set according to actual needs so as to enable the first clamping jaw 322 to be opened and drive the O-ring 5 to move.

[0070] Optionally, the O-ring positioning mechanism 4 further includes a sensor 42 , which is disposed on the sliding member 412 and can sense whether the O-ring 5 is located at a preset position on the sliding member 412 .

[0071] The sensor 42 is connected to the sliding member 412 and can move horizontally with the sliding member 412. The two ends of the sensor 42 are respectively arranged on both sides of the positioning groove 4121, so that the sensor 42 can sense the placement of the O-ring 5 on the positioning groove 4121, so as to detect whether the O-ring 5 dropped from the conveying part is located at the preset position on the positioning groove 4121, so as to ensure that the subsequent O-ring grabbing mechanism 3 can grab it normally. The setting of the sensor 42 can also timely detect the deviation of the falling position of the O-ring 5, so as to make timely corrections. In this embodiment, the O-ring 5 can be moved from the conveying part to the sliding member 412 by vibration. Preferably, a bearing member can be arranged on the sliding member 412, so that the positioning groove 4121 and the sensor 42 are both arranged on the bearing member, so as to fix the sensor 42 and reduce the difficulty of installation. Specifically, the sensor 42 is an optical fiber sensor.

[0072] Preferably, the support 1 is further provided with a control mechanism 7, which can be arranged at the lower end of the support 1, so as to maintain the stability of the support 1 and reduce the space occupied in the horizontal direction. The control mechanism 7 is electrically connected to the material holding assembly 11, the workpiece grasping mechanism 2, the O-ring grasping mechanism 3 and the O-ring positioning mechanism 4, so as to control the movement of each structure, and to set the linkage relationship between each part as needed, so as to achieve the purpose of sleeve the O-ring 5 on the workpiece 6.
