[0030] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In the detailed description below, many specific details are proposed to provide a comprehensive understanding of the present application. However, it is obvious to those skilled in the art that the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating examples of the present application. In the accompanying drawings and the following description, at least some of the known structures and technologies are not shown to avoid unnecessary ambiguity in the present application; and, for clarity, the size of some structures may be exaggerated. In addition, the features, structures or characteristics described below may be combined in one or more embodiments in any suitable manner.
[0031] The directional words appearing in the following description are all directions shown in the figures, and do not limit the specific structure of the assembly device and the robotic arm of the present application. In the description of the present application, it should also be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.
[0032] In order to better understand this application, Figures 1 to 5 The assembly device and the robot arm of the embodiment of the present application are described in detail.
[0033] See also Figure 1 The embodiment of the present application proposes an assembly device 100 for assembling a sealing ring. The assembly device 100 includes a base 10 and an adjusting ring body 20. The adjusting ring body 20 is arranged on the base 10. The adjusting ring body 20 includes a plurality of movable monomers 21. At least a portion of the plurality of movable monomers 21 encloses the adjusting ring body 20 for the sealing ring to be sleeved. The plurality of movable monomers 21 are movably connected to the base 10 along the inner and outer directions. The movable monomers 21 are moved relative to the base 10 to adjust the size of the adjusting ring body 20 so that the sealing ring is sleeved on the adjusting ring body 20.
[0034] As shown in the figure, in this embodiment, multiple movable units 21 are all enclosed to form an adjustment ring body 20, and each movable unit 21 can move relative to the base 10 along the inner and outer directions, wherein the inner and outer directions refer to the inside and outside of the adjustment ring body 20 formed by the movable units 21, and can also be understood as radial movement along the adjustment ring body 20.
[0035] It is understandable that in the process of adjusting the adjustment ring body 20, each movable unit 21 needs to be moved synchronously to achieve the adjustment of the adjustment ring body 20 in the inner and outer directions, thereby ensuring the integrity of the adjustment ring body 20 so that the sealing ring can be smoothly mounted on the adjustment ring body 20.
[0036] Optionally, the sealing ring can be an O-ring structure, and the sealing ring can be assembled using the assembly device 100 in this embodiment. It should be noted that the assembly device 100 can be used for the installation of sealing rings required at various positions and can be applied to various technical fields, rather than being limited to a specific technical field.
[0037] With regard to the structure of the assembly device 100 in this embodiment, the base 10 can be a disc-shaped base structure, one end of the base 10 is used to connect to the robot arm and an adjustment ring body 20 is provided on the other end surface. The adjustment ring body 20 can perform telescopic reciprocating motion on the base 10 relative to the base 10, thereby forming different ring body sizes.
[0038] Specifically, the adjustment ring body 20 is formed by a plurality of movable monomers 21. The present application does not impose any special limitation on the number of movable monomers 21, which can be determined according to the size of the sealing ring to be sleeved as actually required. For example, in this embodiment, three movable monomers 21 are taken as an example for explanation.
[0039] Each mobile unit 21 can move relative to the base 10 after being connected to the base 10. For example, after each mobile unit 21 is moved radially, the overall radial size of the adjustment ring body 20 can be adjusted to meet the socketing of sealing rings of different radial sizes. The present application does not impose any special limitation on the movement mode of the mobile unit 21, and it is sufficient to realize the movement and adjustment of the mobile unit 21 on the base 10.
[0040] The moving range of each movable unit 21 on the base 10 determines the overall size adjustment range of the adjusting ring body 20. The size adjustment range of the adjusting ring body 20 can be set according to the size of the sealing ring actually required to be assembled to meet the assembly of sealing rings of different sizes and avoid problems such as the sealing ring being too large or too small, which makes it impossible to fit into the adjusting ring body 20.
[0041] When the sealing ring needs to be assembled, the specific process is to first adjust the position of each movable unit 21 on the base 10, and adjust the overall size of the adjusting ring body 20 to a smaller state, so that the size of the adjusting ring body 20 is smaller than the size of the sealing ring to be assembled. At this time, the robotic arm can be used to drive the assembly device 100 downward so that the adjusting ring body 20 can be inserted into the sealing ring.
[0042] Then, the position of each movable unit 21 is adjusted again to gradually increase the overall size of the adjusting ring body 20. Since the sealing ring is usually made of flexible materials such as rubber and has a certain shrinkage performance, when the adjusting ring body 20 gradually increases, radial pressure will be generated on the sealing ring, so that the sealing ring will gradually be expanded after being subjected to pressure, and will have a larger size compared to the static state. At this time, due to the static friction between the adjusting ring body 20 and the sealing ring, the sealing ring can be firmly mounted on the adjusting ring body 20 and will not fall off.
[0043] Finally, the assembly device 100 is driven upward by a robotic arm to complete the picking of the sealing ring, and then the sealing ring is moved to the top of the matching structure, and the adjusting ring body 20 is driven downward by the robotic arm so that the matching structure is located inside the adjusting ring body 20, and the sealing ring is gradually moved downward relative to the adjusting ring body 20 until it is detached from the adjusting ring body 20 and then sleeved on the matching structure, completing the assembly process of the sealing ring.
[0044] When assembling the sealing ring, no matter what the size of the sealing ring is, the size of the adjusting ring body 20 can be adjusted to achieve the sleeve connection with the sealing ring, thereby completing the above transfer and assembly process.
[0045] The embodiment of the present application provides an assembly device 100, by setting an adjustment ring body 20 on the base 10 of the assembly device 100, and enclosing the adjustment ring body 20 by a movable unit 21, and utilizing the characteristic that the movable unit 21 can move relative to the base 10, the position of the movable unit 21 on the base 10 can be adjusted according to different actual needs, thereby adjusting the overall size of the adjustment ring body 20, so that the adjustment ring body 20 can adapt to sealing rings of different sizes and meet the conditions that sealing rings of various specifications can be sleeved on the adjustment ring body 20, and finally the adjustment ring body 20 is used to complete the transfer and assembly of the sealing ring, and the adjustment function of the assembly device 100 can better adapt to the assembly of sealing rings of different sizes, thereby improving the flexibility and diversity of the assembly, having better assembly capabilities, and not affecting the assembly efficiency.
[0046] As an alternative embodiment, see Figure 1 and Figure 2 The assembly device 100 includes a driving component 30 arranged on the base 10, the driving component 30 includes a rotating member and a transmission member, the rotating member is rotatably connected to the base 10, the transmission member is transmission-connected to the rotating member, the transmission member has a guide groove 33 whose extension direction intersects with the inner and outer directions, and the movable unit 21 is provided with a matching portion, which is movably matched with the guide groove 33 along the extension direction of the guide groove 33.
[0047] Optionally, the rotating part includes a gear 31 and the transmission part includes a plurality of racks 32, the rack 32 has a guide groove 33, the moving unit 21 is arranged on the side of the rack 32 away from the base 10 and is inserted into the guide groove 33, the moving unit 21 can move relative to the rack 32 in the guide groove 33, and the tangent direction of the meshing point between the rack 32 and the gear 31 intersects with the extension direction of its own guide groove 33.
[0048] Optionally, the movement of each mobile unit 21 on the base 10 can be achieved by utilizing the drive of the driving component 30. Specifically, the driving component 30 is set to a gear 31 and a plurality of racks 32 that mesh with each other, and the mobile unit 21 is set on the rack 32. Since the present embodiment is described by taking the setting of three mobile units 21 as an example, the corresponding number of racks 32 is also three, and the three racks 32 are meshed at circumferential intervals around the gear 31.
[0049] Among them, each rack 32 can adopt a block structure, and each rack 32 is respectively engaged along the tangential direction of the gear 31. When the motor drives the gear 31 to rotate, the gear 31 can drive multiple racks 32 to rotate. Since the two are connected by the tangential engagement of the gear 31, the rack 32 rotates along the tangential direction of the gear 31 during rotation.
[0050] A guide groove 33 is provided on each rack 32 , and the guide groove 33 extends along a single direction. Each moving unit 21 is inserted into the guide groove 33 on the rack 32 , thereby forming a connection between the two, wherein the moving unit 21 can move relative to the rack 32 in the guide groove 33 .
[0051] The extension direction of the guide groove 33 is set to intersect with the tangent of the meshing position of the corresponding rack 32 and the gear 31, so that the guidance of the guide groove 33 to the moving unit 21 and the direction of the tangent form a composite direction, that is, the moving direction of each moving unit 21 relative to the base 10, and the extension direction of the guide groove 33 determines the final composite direction. Optionally, the extension direction of the guide groove 33 on each rack 32 can be set accordingly according to the required moving direction of the moving unit 21. The present application does not impose any special limitation on the extension direction of the guide groove 33.
[0052] When it is necessary to adjust the adjustment ring body 20 on the base 10 according to the sealing ring of different sizes, it is necessary to adjust the position of each mobile unit 21 on the base 10 respectively. At this time, the driving assembly 30 is turned on, and the gear 31 can drive the multiple racks 32 to rotate, thereby driving the mobile units 21 on the racks 32 to form a tangential rotation. At the same time, due to the setting of the guide groove 33 on the rack 32, the mobile unit 21 will move along the guide groove 33 due to the centrifugal force during rotation. Therefore, the mobile unit 21 will move along the synthetic direction of the two directions under the combined action of the tangential rotation and the guided movement of the guide groove 33, thereby realizing the movement of each mobile unit 21 relative to the base 10.
[0053] When the plurality of movable units 21 move relative to the base 10 at the same time, the size of the integrally formed adjusting ring body 20 changes. The size of the adjusting ring body 20 can be increased or decreased as required to meet the sleeve connection requirements of the sealing ring.
[0054] An embodiment of the present application provides an assembly device 100. By configuring the drive component 30 as a structure in which a gear 31 meshes with a plurality of racks 32, a driving method for moving a mobile unit 21 relative to a base 10 is provided. The driving method can enable a plurality of mobile units 21 to move relative to the base 10 at the same time, so that the entirety of the adjustment ring body 20 contracts and stretches evenly, thereby ensuring uniformity when the sealing ring is sleeved, avoiding irregular deformation of the sealing ring, and reducing damage to the sealing ring.
[0055] As an alternative embodiment, see Figure 2 The combined direction of the tangent direction at the meshing point between the rack 32 and the gear 31 and the extension direction of its own guide groove 33 is the radial direction of the adjustment ring body 20 , and the movable unit 21 can move radially relative to the base 10 on the rack 32 .
[0056] Optionally, the combined direction of the tangent direction at the rack 32 and the extension direction of the guide groove 33 can be the radial direction of the adjustment ring body 20, that is, when the size of the adjustment ring body 20 is adjusted, each movable unit 21 moves along the radial direction, and the adjustment ring body 20 as a whole forms radial adjustment.
[0057] In this way, when the adjusting ring body 20 is adjusted, the adjusting ring body 20 maintains a concentric shrinkage or expansion, thereby adapting to concentric sleeve sealing rings of different diameters. Sealing rings of various diameters can be sleeved on the adjusting ring body 20 of the assembly device 100.
[0058] The embodiment of the present application provides an assembly device 100, which realizes the radial adjustment of the adjustment ring body 20 by moving each movable unit 21 in the radial direction, satisfies the socket connection of sealing rings of different diameters, makes the sealing ring evenly stressed on the adjustment ring body 20, forms even deformation in the radial direction, and avoids the phenomenon of stress concentration on the sealing ring and causing damage to the sealing ring.
[0059] As an alternative embodiment, see Figure 2 The rack 32 has a plurality of guide grooves 33, and the plurality of guide grooves 33 are arranged parallel to each other.
[0060] Considering the stability of the connection between the mobile unit 21 and the rack 32, a plurality of guide grooves 33 may be provided on the rack 32. Since the guide grooves 33 are mainly used to provide guidance for the mobile unit 21, the plurality of guide grooves 33 need to be arranged parallel to each other to provide guidance for the mobile unit 21 together.
[0061] Since the plurality of guide grooves 33 cover a larger area of the rack 32 , there is a larger contact area between the moving unit 21 and the rack 32 , so that the relative movement of the moving unit 21 on the rack 32 has better stability.
[0062] The embodiment of the present application provides an assembly device 100, which provides better guiding performance for the mobile unit 21 by providing a plurality of mutually parallel guide grooves 33 on the rack 32, thereby avoiding the displacement of the mobile unit 21 during the adjustment process, and at the same time ensuring the plug-in area between the mobile unit 21 and the rack 32, so that the movement of the mobile unit 21 relative to the rack 32 is more stable, preventing the mobile unit 21 from falling off and other undesirable phenomena.
[0063] As an alternative embodiment, see Figure 3 The movable unit 21 includes a movable baffle 22 , and the movable baffle 22 includes an arc-shaped structure. A plurality of movable baffles 22 are enclosed to form an adjusting ring body 20 .
[0064] Optionally, the movable baffle 22 may adopt a bearing structure. Since the adjustment ring body 20 formed by the enclosure is a ring structure, each movable baffle 22 adopts an arc structure, and the adjustment ring body 20 can be formed after being spliced end to end.
[0065] Optionally, the movable baffle 22 can be set to different heights according to different actual needs. Since the movable baffle 22 needs to be socketed by the sealing ring, a suitable height needs to be set to ensure the stability of the socketing between the sealing ring and the adjustment ring body 20. The present application does not make any special restrictions on the height of the movable baffle 22, so as to facilitate the socketing of the sealing ring.
[0066] The embodiment of the present application provides an assembly device 100, which sets the movable unit 21 as a movable baffle 22, allows the sealing ring to be sleeved on the movable baffle 22, and adjusts the movable baffle 22 to a suitable height, so that the sleeve connection between the sealing ring and the movable baffle 22 has higher stability, avoids the sealing ring from falling off during the transfer process, and has higher assembly reliability.
[0067] As an alternative embodiment, see Figure 3 The moving unit 21 includes an adapter 23, which is arranged on a side of the moving baffle 22 close to the rack 32. The adapter 23 has a protrusion on the side close to the rack 32. The adapter 23 is inserted into the guide groove 33 through the protrusion to connect the moving unit 21 to the rack 32.
[0068] Optionally, the adapter 23 is a block structure, and the movable baffle 22 can be set on the adapter 23. The protrusion at the bottom of the adapter 23 is used to connect with the guide groove 33 on the rack 32. At the same time, the protrusion can also be used to drive the movable baffle 22 to move in the guide groove 33.
[0069] The present application does not impose any special restrictions on the specific structure of the adapter 23, so that the protrusion at the bottom of the adapter 23 can be plugged into the guide groove 33, and the movable baffle 22 is connected to the rack 32 through the adapter 23. The movable baffle 22 and the rack 32 are indirectly connected. The plug-in relationship between the adapter 23 and the guide groove 33 can be understood as the reciprocating sliding of the slider on the guide rail.
[0070] When the gear 31 starts to rotate, it drives the rack 32 meshing with it to rotate together. The adapter 23 in the guide groove 33 will move in the guide groove 33 due to the centrifugal force during rotation, and combined with the movement direction of the rack 32, it will produce movement relative to the base 10, so that the adapter 23 drives the movable baffle 22 connected to it to move, thereby realizing the overall size adjustment of the adjustment ring body 20.
[0071] The embodiment of the present application provides an assembly device 100, which forms an indirect connection between the moving baffle 22 and the rack 32 by setting an adapter 23 in the moving unit 21. The moving direction is transmitted by the adapter 23, thereby avoiding a direct connection between the moving baffle 22 and the rack 32, so that the moving unit 21 as a whole has better stability during the movement process.
[0072] As an alternative embodiment, see Figure 3 The mobile unit 21 includes a transmission mechanism 24, which includes an active component, a passive component and a driving motor 24c. The active component is arranged on the mobile baffle 22 and connected to the passive component. The passive component is sleeved on the mobile baffle 22. The driving motor 24c is transmission-connected to the active component. The active component can drive the passive component to move relative to the mobile baffle 22.
[0073] Optionally, the active component includes a transmission wheel 24b and the passive component includes a conveyor belt 24a, the conveyor belt 24a is arranged around the movable baffle 22 along the height direction of the movable baffle 22, the transmission wheel 24b is arranged between the conveyor belt 24a and the movable baffle 22 and is connected to the driving motor 24c, and the driving motor 24c can drive the transmission wheel 24b to rotate to drive the conveyor belt 24a to move relative to the movable baffle 22.
[0074] Considering that after the sealing ring is completely fitted with the adjustment ring body 20, it is necessary to take off the sealing ring after moving to a predetermined position, and the prior art method of using a guide rod to push the sealing ring is not suitable for sealing rings with larger widths, the conveying mechanism 24 can be used in this embodiment to realize automatic assembly of the sealing ring.
[0075] Specifically, the conveying mechanism 24 is configured as a conveyor belt 24a, a conveyor wheel 24b and a driving motor 24c. The conveyor belt 24a is arranged around the height direction of the movable baffle 22. When the driving motor 24c is turned on, the driving motor 24c drives the conveyor wheel 24b to rotate, and the conveyor wheel 24b further drives the conveyor belt 24a to rotate, and the conveyor belt 24a can start to convey relative to the movable baffle 22.
[0076] Since the sealing ring is sleeved on the outer wall of the movable baffle 22, when the conveyor belt 24a starts to convey, the sealing ring on the outer wall is driven to move together until the sealing ring is separated from the movable baffle 22 and sleeved to a predetermined position, completing the automatic installation of the sealing ring.
[0077] Optionally, different numbers of conveying mechanisms 24 can be set according to different assembly requirements. The more conveying mechanisms 24 there are, the better the assembly capacity of the sealing ring will be, and the higher the assembly efficiency will be, so that the sealing ring can be separated from the movable baffle 22 more quickly to complete the assembly. For example, two sets of conveyor belts 24a can be set at intervals as needed, and after the drive motor 24c is turned on at the same time, the sealing ring is conveyed together. The present application does not specifically limit the number of conveying mechanisms 24.
[0078] As for the coverage area of the conveyor belt 24a, the larger the coverage area is, the larger the contact area with the sealing ring is, so that the sealing ring can be better transported by the conveyor belt 24a to achieve automatic assembly.
[0079] Of course, in order to improve the transmission efficiency of the transmission mechanism 24, multiple transmission wheels 24b connected to the conveyor belt 24a can be set, and the frequency of the driving motor 24c can be replaced to increase the transmission speed of the conveyor belt 24a, etc., as long as the frequency adjustment is performed on the basis of completing automatic transmission.
[0080] Since the conveyor belt 24a is transported relative to the movable baffle 22, in order to further improve the transport efficiency of the conveyor belt 24a, the conveyor belt 24a can also be made of low-friction material to reduce the friction between the movable baffle 22, while also reducing the risk of wear of the conveyor belt 24a. The friction can also be reduced by applying lubricating oil between the two. The present application does not specifically limit the specific method of improving the transport efficiency.
[0081] Optionally, a conveying mechanism 24 can be set on each movable unit 21, so that when the sealing ring is assembled, the conveyor belts 24a on each movable unit 21 can work simultaneously to jointly push the sealing ring downward to separate from the movable baffle 22, making the separation of the sealing ring smoother and avoiding the imbalance of the sealing ring.
[0082] The embodiment of the present application provides an assembly device 100, which disposes a conveying mechanism 24 on a movable unit 21, and utilizes a driving motor 24c to drive the movement of a conveyor belt 24a, thereby driving the automatic removal and installation of the sealing ring, thereby realizing an automatic assembly process of the sealing ring. On the basis of sleeve transfer of sealing rings of different sizes, it is suitable for the assembly of sealing rings of various sizes, thereby improving the applicability of the assembly device 100, while reducing the labor of manual assembly, reducing the difficulty of assembly, improving the assembly efficiency of the sealing ring, and having a better automation effect.
[0083] As an alternative embodiment, see Figure 4 The conveying mechanism 24 further includes a friction portion 24d, which is disposed on the conveying belt 24a and protrudes from the conveying belt 24a, and the friction portion 24d is configured to drive the sealing ring to move.
[0084] Optionally, the friction part 24d can adopt a structure such as a plurality of wedge blocks, and the friction part 24d can be set on the outer surface of the conveyor belt 24a, so that the friction part 24d can contact the sealing ring and complete the transmission. The position where the friction part 24d contacts the sealing ring has a larger friction force, and the friction force between the two can better drive the sealing ring to move downward.
[0085] The present application does not make any special limitation on the specific structure of the friction portion 24d. Any structure that can increase the friction force when the conveyor belt 24a contacts the sealing ring and facilitates the detachment of the sealing ring is acceptable. Optionally, the friction portion 24d can be provided locally on the conveyor belt 24a, or on the entire conveyor belt 24a as required.
[0086] The embodiment of the present application provides an assembly device 100, which provides a friction portion 24d on the conveyor belt 24a and utilizes the friction between the friction portion 24d and the sealing ring to further provide power for the movement of the sealing ring, making it easier for the sealing ring to detach from the movable baffle 22, thereby completing the assembly process of the sealing ring and having higher assembly efficiency.
[0087] As an alternative embodiment, see Figure 4 and Figure 5 The end of the movable baffle 22 facing away from the rack 32 has a guide surface 25 , and the guide surface 25 extends toward the inside of the adjustment ring body 20 .
[0088] Since the sealing ring needs to be gradually separated from the movable baffle 22, a guide surface 25 can be set at the end of the movable baffle 22 away from the rack 32 in this embodiment, and the guide surface 25 is gradually extended toward the inside of the ring body, thereby providing an effective transition for the sealing ring to slide off the outer wall of the movable baffle 22.
[0089] Optionally, the inclination angle of the guide surface 25 of the movable baffle 22 relative to the outer wall can be set according to actual needs. When the sealing ring moves to the guide surface 25, due to a certain step difference, the sealing ring can more easily slide out of the movable baffle 22 at the guide surface 25 with the help of the inclination angle, thereby completing the assembly of the sealing ring.
[0090] The embodiment of the present application provides an assembly device 100, which sets a guide surface 25 at the end of the movable baffle 22. The step formed by the guide surface 25 helps the sealing ring to slide down, making it easier to complete the assembly and reducing the friction resistance between the sealing ring and the movable baffle 22.
[0091] An embodiment of the present application provides a robotic arm, comprising the assembly device 100 as described above.
[0092] The embodiment of the present application provides an assembly device and a robotic arm. An adjustment ring body is provided on the base of the assembly device and is formed by enclosing a movable unit. The movable unit can be moved relative to the base to adjust the position of the movable unit on the base according to different actual needs, thereby adjusting the overall size of the adjustment ring body so that the adjustment ring body can adapt to sealing rings of different sizes and meet the conditions for sealing rings of various specifications to be sleeved on the adjustment ring body. Finally, the adjustment ring body is used to complete the transfer and assembly of the sealing ring. The adjustment function of the assembly device can better adapt to the assembly of sealing rings of different sizes, thereby improving the flexibility and diversity of the assembly and having better assembly capabilities without affecting the assembly efficiency.
[0093] Although the present application has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present application. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there are no structural conflicts. The present application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
