[0037] This embodiment provides a posture adjustment structure 20, such as Figures 2-6 As shown, the device includes a base 100, a rotating assembly 200, a clamping assembly 300, and an attitude recognition assembly 400. The rotating assembly 200 is disposed on the base 100 and has a through channel 210 extending along the X direction. The clamping assembly 300 is tractively connected to the rotating assembly 200 and is configured to clamp the part 10 to be adjusted and rotate under the drive of the rotating assembly 200 to adjust the circumferential angle of the part 10 to be adjusted. The attitude recognition assembly 400 is disposed on the base 100, and the attitude recognition assembly 400, the through channel 210, and the clamping assembly 300 are arranged sequentially along the X direction. The attitude recognition assembly 400 is configured to recognize the attitude of the part 10 to be adjusted held by the clamping assembly 300 through the through channel 210.
[0038] This embodiment also provides an assembly fixture, including a feeding device, a fastening device, and the above-mentioned posture adjustment structure 20. The feeding device, posture adjustment structure 20, and fastening device are configured such that: the feeding device transfers the part to be adjusted 10 to the posture adjustment structure 20, the posture adjustment structure 20 adjusts the circumferential angle of the part to be adjusted 10, and transfers the adjusted part after adjusting the circumferential angle to the fastening device.
[0039] The posture adjustment structure 20 provided in this embodiment is used to adjust the circumferential angle of the part to be adjusted 10. The posture recognition component 400 and the clamping component 300 are located on the outer side of the first end and the outer side of the second end of the through channel 210 along the X direction, respectively. During the rotation of the clamping component 300 driven by the rotating component 200, its clamping part is always kept in the extension area of the through channel 210 along the X direction to the outer side of its second end, and there is no obstruction between the clamping part and the through channel 210, so that the posture recognition component 400 can recognize the posture of the part to be adjusted 10 clamped by the clamping part through the through channel 210.
[0040] When the posture adjustment structure 20 is applied to the assembly fixture, the feeding device transports the workpiece 10 with an uncertain circumferential angle to a position near the clamping part of the clamping assembly 300. At this time, the workpiece 10 is located outside the through channel 210 and in the extension area of the through channel 210. There is no obstruction between the posture recognition assembly 400 and the workpiece 10, and the posture of the workpiece 10 can be recognized through the through channel 210. When the circumferential angle of the workpiece 10 does not meet the assembly requirements, the clamping assembly 300 can clamp the workpiece 10 transferred by the feeding device, and drive the clamping assembly 300 to rotate the workpiece 10 by the corresponding circumferential angle so that the circumferential angle of the workpiece 10 meets the assembly requirements, thereby realizing a first posture adjustment of the workpiece 10. After the initial posture adjustment is completed, the clamping part clamps the workpiece 10. The adjusting component 10 is still located in the extension area of the through channel 210. The attitude recognition component 400 can re-check and recognize the adjusting component 10 through the through channel 210. When the circumferential angle of the adjusting component 10 still does not meet the assembly requirements, the corresponding circumferential angle is rotated again by the rotation component 200 to achieve a secondary attitude adjustment of the adjusting component 10. This process is repeated until the circumferential angle of the adjusting component 10 meets the assembly requirements and becomes the adjusting component, thus completing the adjustment of the circumferential angle of the adjusting component 10. Subsequently, the clamping component 300 transfers the adjusting component after the circumferential angle adjustment to the fastening device. The fastening device carries the adjusting component into the assembly process to perform a fastening operation. The adjusting component with a precise circumferential angle can ensure effective assembly with the component to be assembled in the assembly process and reduce the damage to the adjusting component 10 caused during the assembly process.
[0041] In the posture adjustment structure 20 provided in this embodiment, the posture recognition component 400 performs posture recognition and posture verification on the part to be adjusted 10. Then, based on the recognition result, the clamping component 300 is driven to clamp the part to be adjusted 10 and perform corresponding circumferential angle rotation adjustment, thereby adjusting the posture of the part to be adjusted 10 to meet the assembly requirements and become an adjustment part. This ensures the effective assembly of the adjustment part with the part to be assembled in subsequent assembly processes and reduces damage to the adjustment part caused by the assembly process. In addition, in this posture adjustment structure 20, the posture recognition component 400 and the clamping component 300 are respectively located on opposite sides of the rotating component 200 along the X direction, and a through channel 210 is provided in the rotating component 200 to connect the posture recognition component 400 and the clamping component 300. While ensuring that the posture recognition component 400 effectively recognizes the posture of the part to be adjusted 10 clamped in the clamping component 300, it reduces the number of posture recognition components 400 and clamping components 300 arranged on the same side of the rotating component 200. Located on the periphery of the clamping assembly 300, it is easy to interfere with the clamping assembly 300's reception of the part to be adjusted 10 or the delivery of the part to be adjusted, thus limiting the occurrence of angle adjustment of the clamping assembly 300, thereby increasing the angle adjustment range of the part to be adjusted 10, and ensuring that the clamping assembly 300 receives the part to be adjusted 10 and delivers the part to be adjusted; at the same time, the attitude recognition assembly 400, the rotation assembly 200 and the clamping assembly 300 are arranged in sequence along the X direction, with a compact structure, which can also reduce the space occupied by the attitude adjustment structure 20 in the Z direction.
[0042] For example, the attitude adjustment structure 20 can adjust the circumferential angle of the component 10 to be adjusted through the following two operation steps:
[0043] The first method: In use, the feeding device transports the part 10 to be adjusted, whose circumferential angle is uncertain, to a position near the clamping part of the clamping assembly 300. At this time, the part 10 to be adjusted is located outside the second end of the through channel 210 and in the extension area of the through channel 210. The posture recognition component 400 performs posture recognition on the part 10 to be adjusted through the through channel 210. When the circumferential angle of the part 10 to be adjusted does not meet the assembly requirements, the rotating component 200 rotates the clamping assembly 300 around the X-axis by the corresponding circumferential angle. Then, the feeding device translates and transfers the part 10 to be adjusted to the clamping assembly 300. The rotating component 200 drives the clamping assembly 300 to rotate back to the initial position with the part 10 to be adjusted. The part 10 to be adjusted rotates around the X-axis by a first preset angle with the clamping assembly 300 so that its circumferential angle meets the assembly requirements, thereby realizing the assembly of the part 10 to be adjusted. Secondary posture adjustment: After the initial posture adjustment is completed, the part to be adjusted 10 is still located in the extension area of the through channel 210. The posture recognition component 400 can re-check and recognize the part to be adjusted 10 through the through channel 210. When the circumferential angle of the part to be adjusted 10 still does not meet the assembly requirements, the clamping component 300 will transfer the coaxial line to the feeding device, and then rotate it to the corresponding second preset angle under the drive of the rotating component 200. Then the feeding device will transfer the part to be adjusted 10 to the clamping component 300. The rotating component 200 will drive the clamping component 300 to carry the part to be adjusted 10 back to the initial position, thereby realizing the secondary posture adjustment of the part to be adjusted 10. This process is repeated until the circumferential angle of the part to be adjusted 10 meets the assembly requirements and becomes an adjusted part. The feeding device will then exit, thus completing the adjustment of the circumferential angle of the part to be adjusted 10.
[0044] The second method involves the feeding device transferring the part 10 to be adjusted, whose circumferential angle is uncertain, to the clamping assembly 300. At this time, the part 10 is located in the extension area of the through channel 210. The attitude recognition assembly 400 can recognize the attitude of the part 10 through the through channel 210. When the circumferential attitude of the part 10 does not meet the assembly requirements, the rotating assembly 200 drives the clamping assembly 300 to rotate the part 10 by a corresponding angle so that the circumferential angle of the part 10 meets the assembly requirements, thereby realizing the first attitude adjustment of the part 10; the initial attitude adjustment is completed. Afterwards, the part to be adjusted 10 is still located in the extension area of the through channel 210. The attitude recognition component 400 can recheck the attitude of the part to be adjusted 10 through the through channel 210. When the circumferential angle of the part to be adjusted 10 still does not meet the assembly requirements, the rotating component 200 drives the clamping component 300 to carry the part to be adjusted 10 to rotate again by a certain angle, thereby realizing the secondary attitude adjustment of the part to be adjusted 10. This is repeated until the attitude recognition component 400 recognizes that the circumferential angle of the part to be adjusted 10 meets the assembly requirements, thereby completing the adjustment of the circumferential angle of the part to be adjusted 10.
[0045] Of course, the adjustment operation steps of the attitude adjustment structure 20 for the adjustment component 10 are not limited to the two methods mentioned above; any other adjustment operation that can be implemented is acceptable.
[0046] Specifically, the attitude recognition component 400 can be a CCD camera. In use, the rotation component 200, the clamping component 300 and the attitude recognition component 400 are all communicatively connected to the controller. The CCD camera takes pictures of the workpiece 10 to be adjusted held by the clamping part through the through channel 210 and transmits the captured image to its controller. The controller recognizes the attitude of the workpiece 10 to be adjusted based on the image and calculates the circumferential angle that the workpiece 10 to be adjusted needs to rotate. The controller then controls the rotation component 200 and the clamping component 300 to operate accordingly to achieve the adjustment of the circumferential angle of the workpiece 10 to be adjusted.
[0047] Specifically, the CCD camera includes a camera, a lens, and a light source, which are arranged sequentially along the X-axis and coaxial with the through channel 210.
[0048] In this embodiment, as Figure 2 and Figure 5 As shown, the through channel 210 coaxially passes through the rotation axis 220 of the rotating assembly 200, and the clamping area of the clamping assembly 300 is coaxial with the through channel 210. The clamping part of the clamping assembly 300 clamps the area enclosed by the positioning part 12 of the member to be adjusted 10 as the clamping area, which is approximately the same as the outer contour of the positioning part 12. The through channel 210 passes through the rotation axis 220 and other areas of the rotation assembly 200 along the X direction. During the circumferential angle adjustment, with the rotation axis 220 as the reference, as the rotation assembly 200 drives the clamping assembly 300 to rotate through its rotation axis 220, the through channel 210 and the clamping area of the clamping part of the clamping assembly 300 remain coaxial with the rotation axis 220. They only rotate circumferentially and do not undergo radial displacement. Correspondingly, the position of the member to be adjusted 10 clamped in the clamping area remains approximately fixed during the circumferential angle adjustment. It always remains coaxial with the through channel 210 and can be ensured to be located in the recognition area of the attitude recognition component 400. This ensures that the recognition component can effectively recognize the member to be adjusted 10 in the full range, reduces the limitation of the recognition angle, and reduces the requirements of the recognition range of the attitude recognition component 400.
[0049] In this embodiment, as Figures 2-6As shown, the attitude adjustment structure 20 also includes a lifting component 500, which is configured to lift the assembly part 11 of the adjustment component after circumferential angle adjustment. The part to be adjusted 10 includes a positioning part 12 and an assembly part 11. The positioning part 12 is used to be clamped and positioned by the clamping part of the clamping assembly 300. The assembly part 11 is used to fasten and assemble with the part to be assembled in the assembly process. When the clamping part clamps the positioning part 12, the assembly part 11 extends out of the clamping area of the clamping part. Initially, the lifting assembly 500 is located in the avoidance position to avoid the clamping assembly 300, so as to ensure that the clamping assembly 300 and the rotating assembly 200 cooperate to clamp and rotate the part to be adjusted 10. When the circumferential angle of the part to be adjusted 10 is adjusted and it becomes an adjustment part, the lifting assembly 500 extends upward and lifts the assembly part 11 to ensure that the assembly part 11 maintains its current posture and reduces the occurrence of changes in the posture of the assembly part 11 due to drooping and displacement. Furthermore, the fastening device can receive adjustment parts with high circumferential angle accuracy and carry the adjustment parts for fastening operation, thereby ensuring the effective fastening and assembly of the assembly part 11.
[0050] Specifically, in this embodiment, as Figure 2 , Figure 3 and Figure 5 As shown, the lifting assembly 500 includes a lifting drive unit 510 and a lifting arm 520. The lifting drive unit 510 is fixed to the base 100. The lifting arm 520 includes a connecting arm body 521 and a lifting arm 520 body connected to each other. The connecting arm body 521 is slidably connected to the housing of the clamping assembly 300 or the rotation shaft 220 of the rotating assembly 200. The clamping assembly 300 has a lifting position. When the clamping assembly 300 is in the lifting position, the lifting drive unit 510 and the lifting arm 520 are configured such that the lifting drive unit 510 can push the connecting arm body 521 upward along the Z direction to drive the lifting arm 520 body to lift the assembly part 11 of the adjustment member upward.
[0051] The lifting drive unit 510 and the lifting arm 520 of the lifting assembly 500 are separately arranged. Initially, the lifting drive unit 510 is in a retracted state, and there is no connection between the lifting drive unit 510 and the lifting arm 520. During the process of the rotating assembly 200 driving the clamping assembly 300 to clamp the member to be adjusted 10 and rotate to adjust the circumferential angle of the member to be adjusted 10, the lifting arm 520 rotates synchronously with the clamping assembly 300, while the lifting drive unit 510 remains in a fixed position. On the basis of adjusting the circumferential angle of the member to be adjusted 10, the circumferential space occupied by the entire lifting assembly 500 as the clamping assembly 300 rotates is reduced, thereby reducing the circumferential space occupied by the posture adjustment structure 20 during construction and improving its structural compactness.
[0052] By adjusting the operation of the rotating component 200 and the clamping component 300, the clamping component 300 is positioned in the lifting position when it clamps the part to be adjusted 10 and completes the circumferential angle adjustment, as described in the first operation method above. After the circumferential angle adjustment of the part to be adjusted 10 is completed, the clamping component 300 is in the initial position, which can be set as the lifting position. When the clamping component 300 is in the lifting position, the connecting arm 521 of the lifting arm 520 is located directly above the lifting drive unit 510, and the lifting arm 520 body is located directly below the assembly unit 11. The lifting drive unit 510 extends upward and connects to the lifting arm 520. The bottom end of the arm 521 abuts against and continues to push the connecting arm 521 and the lifting arm 520 upward, so that the lifting arm 520 lifts the assembly part 11 upward, so that the assembly part 11 maintains its current posture, thereby improving the posture stability and accuracy of the assembly part 11 and ensuring its effective fastening assembly with the part to be assembled; after the clamping assembly 300 transfers the adjustment part to the fastening device, the lifting drive part 510 retracts downward to the initial position and no longer lifts the connecting arm 521, and the connecting arm 521 and the lifting arm 520 return to their original positions under the action of gravity.
[0053] Preferably, in this embodiment, as Figure 2 and Figure 3 As shown, an elastic reset member 610 is connected between the lifting arm 520 and the housing or rotating shaft 220. The elastic reset member 610 is configured to pull the lifting arm 520 away from the clamping part of the clamping assembly 300. When lifting is required, the lifting drive unit 510 can push the connecting arm body 521 upward to overcome the restoring force of the elastic reset member 610, so that the lifting arm 520 body lifts the assembly part 11 upward. After the adjustment member is transferred to the fastening device, the lifting drive unit 510 moves downward to disengage from the connecting arm body 521. The restoring force of the elastic reset member 610 drives the connecting arm body 521 downward until the lifting arm 520 body abuts against the housing or rotating shaft 220, to ensure that the lifting arm 520 body does not interfere with the clamping operation of the clamping part, and to ensure the connection stability between the connecting arm body 521 and the housing or rotating shaft 220.
[0054] Specifically, in this embodiment, as Figure 2 , Figure 3 and Figure 5As shown, the lifting arm 520 includes a first arm segment 522a and a second arm segment 522b along its length. The end of the first arm segment 522a facing away from the second arm segment 522b is fixed to the connecting arm body 521. The lifting side of the second arm segment 522b is provided with a lifting boss 522c, which corresponds to the assembly part 11 of the part to be adjusted 10. The lifting boss 522c protrudes upward relative to the first arm segment 522a. During the lifting process, when the lifting boss 522c lifts the assembly part 11 upward, the height of the second arm segment 522b is lower. This ensures that the lifting boss 522c effectively lifts the assembly part 11 while reducing interference and collisions caused by the second arm segment 522b to the clamping part, etc.
[0055] Optionally, in this embodiment, as Figures 2-6 As shown, the clamping assembly 300 includes a clamping drive unit 310 and a first jaw 320 and a second jaw 330 connected to the clamping drive unit 310. The clamping drive unit 310 is configured to drive the first jaw 320 and the second jaw 330 to move towards or away from each other. In use, the clamping drive unit 310 can drive the first jaw 320 and the second jaw 330 to move away from each other to create a gap between them. When it is necessary to clamp the member to be adjusted 10, the positioning part 12 of the member to be adjusted 10 enters the gap between the first jaw 320 and the second jaw 330. Then, the clamping drive unit 310 drives the first jaw 320 and the second jaw 330 to move towards each other until the positioning part 12 is clamped, thereby achieving the clamping and positioning of the member to be adjusted 10. Similarly, when transferring the member to the fastening device, the clamping drive unit 310 drives the first jaw 320 and the second jaw 330 to move away from each other to release the positioning part 12, thereby transferring the member to the fastening device.
[0056] Specifically, the clamping drive unit 310 can be a parallel cylinder to drive the first gripper 320 and the second gripper 330 to move towards each other or away from each other.
[0057] When the clamping assembly 300 adopts the above-described form, such as Figure 2 , Figure 3 and Figure 5 As shown, the connecting arm 521 is slidably connected to the housing of the clamping assembly 300 via the guide mechanism 620. The first arm segment 522a of the lifting arm 520 extends to the other side through the space below the clamping area of the first clamp 320 and the second clamp 330. The second arm segment 522b and its lifting boss 522c and the connecting arm 521 are located on opposite sides of the first clamp 320 and the second clamp 330, respectively. When the lifting drive unit 510 pushes the connecting arm 521 upward, the lifting boss 522c has already contacted the assembly unit 11 to achieve lifting before the first arm segment 522a interferes with the first clamp 320 and the second clamp 330 upward.
[0058] In this embodiment, as Figure 4 and Figure 6 As shown, the clamping drive unit 310 is a translation drive unit. The clamping side of the first jaw 320 is provided with a first clamping groove 321 that runs through the X direction. The first clamping groove 321 matches the corresponding clamping area of the part to be adjusted 10, and the circumferential extension area of the first clamping groove 321 is less than half a circumference. The clamping side of the second jaw 330 is provided with a second clamping groove 331 that runs through the X direction. The second clamping groove 331 matches the corresponding clamping area of the part to be adjusted 10, and the circumferential extension area of the second clamping groove 331 is less than half a circumference.
[0059] The first gripper 320 and the second gripper 330 are located away from the ends of the gripping drive unit 310 and serve as gripping parts. The gripping part of the first gripper 320 faces the side wall of the second gripper 330, which is its gripping side. A first gripping groove 321 is provided on the gripping side of the first gripper 320 and extends through it in the X direction. The gripping part of the second gripper 330 faces the side wall of the first gripper 320, which is its gripping side. A second gripping groove 331 is provided on the gripping side of the second gripper 330 and extends through it in the X direction. The second gripping groove 331 and the first gripping groove 321 correspond to each other.
[0060] In use, the clamping drive unit 310 drives the first gripper 320 and the second gripper 330 to move away from each other along the Y direction, and the first clamping groove 321 and the second clamping groove 331 move away from each other to form a gap. When the positioning part 12 of the member to be adjusted 10 enters the gap, the clamping drive unit 310 drives the first gripper 320 and the second gripper 330 to move towards each other along the Y direction until the bottom of the first clamping groove 321 and the second clamping groove 331 clamp the member to be adjusted 10 on both sides of the Y direction. At this time, the outline of the clamping area enclosed by the first clamping groove 321 and the second clamping groove 331 is aligned with the positioning part 12. The outer wall contours are consistent, and the circumferential extension areas of the first clamping groove 321 and the second clamping groove 331 are both less than half a circumference, so that there is a gap between them to ensure the clamping of the positioning part 12. The positioning part 12 is embedded in the first clamping groove 321 and the second clamping groove 331. The area enclosed by the first clamping groove 321 and the second clamping groove 331 can clamp the part to be adjusted 10 and limit its radial position, so as to further improve the positional accuracy and stability of the clamping component in clamping the part to be adjusted 10, and correspondingly further improve the accuracy of the attitude adjustment structure 20 in adjusting the circumferential angle of the part to be adjusted 10.
[0061] In this embodiment, as Figure 4 and Figure 6As shown, of the clamping sides of the first gripper 320 and the second gripper 330, one has an insertion groove 322 and the other has an insertion protrusion 332, which matches the insertion groove 322. When clamping the part to be adjusted 10, the clamping drive unit 310 drives the first gripper 320 and the second gripper 330 to move towards each other, and the insertion protrusion 332 is inserted into the insertion groove 322 to limit the relative position of the first gripper 320 and the second gripper 330 in the X direction, thereby further improving the accuracy and stability of the first gripper 320 and the second gripper 330 in clamping the part to be adjusted 10.
[0062] This embodiment also provides an attitude adjustment device, such as... Figure 1 As shown, the device includes two posture adjustment structures 20, which are symmetrically arranged along the X-axis, and the clamping components 300 of the two posture adjustment structures 20 are arranged facing each other. Both posture adjustment structures 20 in this posture adjustment device can adjust the circumferential angle of the part 10 to be adjusted. Specifically, they can be used for posture adjustment at both ends of the same part 10, such as adjusting the circumferential angle of the two end fastening heads of a coaxial line, thereby improving the adjustment efficiency and functionality of the posture adjustment device.
[0063] Specifically, the bases 100 of the two attitude adjustment structures 20 can be used independently or share the same base 100.
