Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0037] It should be noted that in this embodiment, the directions or positional relationships indicated by "upper", "lower", "front", "back", etc. are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present application. In addition, "first", "second", "third", and "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
[0038] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0039] Please refer to Figures 1 to 6In this embodiment, an ultrasound probe quick-change device is provided, which includes a mounting assembly 1, a clamping assembly 2 and a telescopic assembly 3. The mounting assembly 1 includes a first mounting plate 11 mounted on the action end of the robot arm and a second mounting plate 12 hinged to the middle of the first mounting plate 11. The first mounting plate 11 and the second mounting plate 12 are rotatably connected through a hinge portion 13. At the same time, the first mounting plate 11 and the second mounting plate 12 are arranged at intervals. A support block 121 is provided between the second mounting plate 12 and the first mounting plate 11. The support block 121 can be fixed on the board surface of the first mounting plate 11 or on the board surface of the second mounting plate 12. No excessive restrictions are made here.
[0040] The clamping assembly 2 includes a first clamping plate 21 and a second clamping plate 22 which are arranged on the side of the second mounting plate 12 away from the first mounting plate 11. The first clamping plate 21 is movably arranged on the second mounting plate 12 in a direction close to the second clamping plate 22, and a clamping space for accommodating an ultrasonic probe is formed between the first clamping plate 21 and the second clamping plate 22; that is, when the first clamping plate 21 moves toward the second clamping plate 22, the two will form abutment, and in the abutment state, a clamping space for clamping the ultrasonic probe is formed.
[0041] The telescopic assembly 3 is arranged on the second mounting plate 12, and the telescopic assembly 3 and the support block 121 are respectively located on both sides of the hinge between the first mounting plate 11 and the second mounting plate 12, that is, distributed on both sides of the hinge portion 13. The telescopic assembly 3 includes a first action end 33 and a second action end 34, the first action end 33 is located between the first mounting plate 11 and the second mounting plate 12, and the second action end 34 is located on the side of the second mounting plate 12 away from the first mounting plate 11. Among them, the second action end 34 is connected to the first clamping plate 21 through the pull rope 5 to drive the first clamping plate 21 to move toward the second clamping plate 22.
[0042] It should be noted that when the second action end 34 is extended, the pull rope 5 will be driven to drive the first clamping plate 21 to move, and when the first clamping plate 21 abuts against the second clamping plate 22, the pull rope 5 will be tightened. As the second action end 34 continues to extend, relying on the reaction force, it will push the first action end 33 to move toward the first mounting plate 11 until the first action end 33 abuts against the first mounting plate 11. The first mounting plate 11 will rotate under the action of the hinge 13, and the other side of the first mounting plate 11 will abut against the support block 121, so that the relative position between the first mounting plate 11 and the second mounting plate 12 is fixed. Next, the second action end 34 continues to extend, forming further tension on the pull rope 5, so that the first clamping plate 21 and the second clamping plate 22 clamp and fix the ultrasonic probe.
[0043] In summary, the present application is connected to the action end of the robotic arm through an installation component 1, and the installation component 1 is provided with a clamping component 2 and a telescopic component 3. The clamping component 2 fixes the ultrasonic probe through a first clamping plate 21 and a second clamping plate 22. The clamping force of the clamping component 2 comes from the telescopic component 3, and the first clamping plate 21 is driven to move by the second action end 34 of the telescopic component 3, thereby forming a clamping space that cooperates with the second clamping plate 22, and when the second action end 34 drives the first clamping plate 21 to form a preliminary clamping, the pull rope 5 can be in a taut state, and as the second action end 34 continues to extend, the reaction force of the pull rope 5 will cause the first action end 33 to move toward and abut the first mounting plate 11, so that under the cooperation of the support block 121, the first action end 33 and the support block 121 can be pressed tightly between the first mounting plate 11 and the second mounting plate 12, forming a fixed connection with the robotic arm. At the same time, when the first action end 33 is pressed against the first mounting plate 11, it can also provide a stable support point for the second action end 34 in the reverse direction, so that when the second action end 34 continues to extend, it further forms a pulling force on the taut pull rope 5, so that the first clamping plate 21 and the second clamping plate 22 change from the initial clamping state to the fixed clamping state, thereby forming a fixed clamping of the ultrasonic probe. When it is necessary to disassemble the ultrasonic probe, it is only necessary to retract the second action end 34 to disengage the first action end 33 from the abutment with the first mounting plate 11, and the first clamping plate 21 and the second clamping plate 22 are disengaged from the clamping state, so that the ultrasonic probe can be quickly disassembled. Therefore, the present application can achieve the fixation between the ultrasonic probe and the mechanical arm without the need for external tools, thereby improving the efficiency and convenience of replacing the ultrasonic probe.
[0044] In some embodiments, the first mounting plate 11 and the second mounting plate 12 can be circular plates, rectangular plates, etc., and there are no excessive restrictions here. They can be set according to actual conditions and fall within the protection scope of this application. The second mounting plate 12 has two opposite connecting plates 122 integrally formed on the plate surface facing away from the first mounting plate 11. The first clamping plate 21 and the second clamping plate 22 are located between the two connecting plates 122. The two sides of the second clamping plate 22 are fixedly connected to the two connecting plates 122. The two sides of the first clamping plate 21 are hingedly connected to the two connecting plates 122. The first clamping plate 21 can rotate toward the second clamping plate 22 with the hinge as the axis.
[0045] The second clamping plate 22 and the two connecting plates 122 can be integrally formed, and the second clamping plate 22 can also be integrally formed with the second mounting plate 12, that is, the second mounting plate 12, the connecting plate 122, and the second clamping plate 22 are integrally formed. Through such a configuration, on the one hand, the two connecting plates 122 realize the hinged connection between the first clamping plate 21 and the second mounting plate 12; on the other hand, the two connecting plates 122 strengthen the upper end of the second clamping plate 22, thereby improving the bending strength of the upper end of the second clamping plate 22.
[0046] The first clamping plate 21 and the second clamping plate 22 are provided with a receiving groove on the opposite side. After the first clamping plate 21 and the second clamping plate 22 are in contact, the two receiving grooves cooperate to form a clamping cavity 23 for receiving the ultrasonic probe, and the side wall of the clamping cavity 23 clamps the ultrasonic probe. In order to reduce the damage of the side wall of the clamping cavity 23 to the ultrasonic probe, the inner surface of the clamping cavity 23 is covered with a flexible layer 24, and the flexible layer 24 can be made of rubber, silicone and other materials.
[0047] In addition, connecting grooves 25 are provided at the ends of the first clamping plate 21 and the second clamping plate 22 facing away from the second mounting plate 12. The connecting groove 25 extends from the first clamping plate 21 to the second clamping plate 22. The pull rope 5 is slidably arranged in the connecting groove 25, and a connecting block 26 is provided in the connecting groove 25 on the first clamping plate 21. The end of the pull rope 5 is connected to the connecting block 26, so that the pull rope 5 pulls the first clamping plate 21 to move along the extension direction of the connecting groove 25, thereby forming a clamping fit between the first clamping plate 21 and the second clamping plate 22.
[0048] To prevent the pull rope 5 from falling off the first clamping plate 21 and the second clamping plate 22, the connecting groove 25 should have a certain groove depth. At the same time, the side of the pull rope 5 facing away from the connecting block 26 extends along the outer plate surface of the second clamping plate 22 toward the second mounting plate 12. A connecting groove 25 can be correspondingly arranged on the outer plate surface of the second clamping plate 22, and the pull rope 5 is located in the connecting groove 25.
[0049] As the pull rope 5 extends, it will enter between the first mounting plate 11 and the second mounting plate 12 at the first through hole 123 on the second mounting plate 12. The second mounting plate 12 is also provided with a second through hole 124 for allowing the pull rope 5 to extend toward the second mounting plate 12 away from the first mounting plate 11. The pull rope 5 extending from the second through hole 124 is connected to the second actuating end 34. When the second actuating end 34 moves away from the second mounting plate 12, that is, when the second actuating end 34 is extended, the pull rope 5 drives the first clamping plate 21 to move toward the second clamping plate 22.
[0050] In this embodiment, the free end of the pull rope 5 is connected to the bottom of the second action end 34. When the second action end 34 extends downward, the pull rope 5 is pulled, and the first clamping plate 21 approaches the second clamping plate 22 to complete the clamping of the ultrasonic probe.
[0051] The telescopic assembly 3 also includes a third mounting plate 31 and a rotating column 32. Two mounting feet are formed on the lower side of the second mounting plate 12, and the third mounting plate 31 is fixed to the bottom of the second mounting plate 12 by the two mounting feet; the rotating column 32 is rotatably arranged on the third mounting plate 31 and is slidably arranged relative to the third mounting plate 31 in the axial direction. The rotating column 32 is located between the third mounting plate 31 and the second mounting plate 12. The interior of the rotating column 32 is hollow, and a baffle 321 is provided in the rotating column 32. The baffle 321 divides the hollow cavity of the rotating column 32 into a first cavity and a second cavity.
[0052] Among them, the second action end 34 is inserted into the second cavity, and the inner wall of the second cavity is threadedly matched with the outer wall of the second action end 34 to form a screw nut structure, so as to drive the second action end 34 to move axially through the rotation of the rotating column 32; the first action end 33 extends toward the first cavity through the second through hole 124, and is inserted into the first cavity to abut against the baffle 321.
[0053] Since the second action end 34 is threadedly connected to the rotating column 32, and the second action end 34 only moves in the axial direction, when the rotating column 32 rotates, the second action end 34 performs telescopic movement. When the rotating column 32 rotates in one direction and the second action end 34 extends downward, the pull rope 5 will gradually tighten as the second action end 34 continues to extend. When the first clamping plate 21 abuts against the second clamping plate 22, the pull rope 5 is already in a tightened state. Therefore, when the rotating column 32 continues to rotate in this direction, the pull rope 5 will hinder the second action end 34 from extending downward, thereby generating an upward reaction force on the rotating column 32, causing the rotating column 32 to rotate and move upward, thereby pushing the first action end 33 to move upward; when the first action end 33 abuts against the first mounting plate 11, the other side of the first mounting plate 11 abuts against the support block 121, and the first mounting plate 11 and the second mounting plate 12 are relatively fixed. At this time, the rotating column 32 cannot continue to rise. If the rotating column 32 is rotated in this direction, the second action end 34 will continue to slightly extend, thereby further tightening the pull rope 5, so that the first clamping plate 21 and the second clamping plate 22 clamp the ultrasonic probe. Under the self-locking of the thread, the position between the second action end 34 and the rotating column 32 is locked, and the second mounting plate 12 and the robot arm are fixedly connected.
[0054] When the staff needs to remove the ultrasonic probe, they rotate the rotating column 32 in the opposite direction to retract the second action end 34, thereby releasing the fixation. At the same time, the reaction force on the first action end 33 will disappear, and the first action end 33 will be separated from the abutment with the first mounting plate 11, so that the first mounting plate 11 and the second mounting plate 12 can move relatively. It can be seen that the ultrasonic probe can be fixed to the mechanical arm only by rotating the rotating column 32, thereby greatly improving the efficiency and convenience of the connection between the ultrasonic probe and the mechanical arm.
[0055] In order to facilitate the rotation of the rotating column 32, a hand wheel 4 is rotatably connected between the second mounting plate 12 and the third mounting plate 31. The outer wall of the hand wheel 4 and the outer wall of the rotating column 32 are provided with mutually meshing spur teeth. The hand wheel 4 extends outward from the third mounting plate 31 to facilitate manual rotation. When the staff needs to rotate the rotating column 32, they only need to rotate the hand wheel 4, and the rotating column 32 can be rotated under the meshing action of the spur teeth; at the same time, since the rotating column 32 is formed with spur teeth and the spur teeth are along the vertical direction, the rotating column 32 can move up and down while rotating.
[0056] A slot hole 311 is provided on the plate surface of the third mounting plate 31 facing the second mounting plate 12, and the rotating column 32 is provided in the slot hole 311. The slot hole 311 needs to meet the rotation and sliding of the rotating column 32. In order to prevent the second action end 34 and the third mounting plate 31 from rotating relative to each other and only slide in the axial direction, an anti-rotation hole 312 circumferentially limited to the outer wall of the second action end 34 can be provided at the position of the slot hole 311. The second action end 34 passes through the third mounting plate 31 through the slot hole 311 and the anti-rotation hole 312 and only slides in the axial direction.
[0057] Specifically, the cross section of the anti-rotation hole 312 can be "D" shaped, and the cross section of the second action end 34 is also correspondingly set in a "D" shape. The second action end 34 and the anti-rotation hole 312 are adapted so that the second action end 34 can only slide axially along the anti-rotation hole 312. Of course, the specific configuration of the anti-rotation hole 312 includes but is not limited to the above-mentioned methods, which will not be described in detail here. It is sufficient to ensure that the second action end 34 can be circumferentially limited and axial sliding can be maintained, which all fall within the protection scope of this application.
[0058] In addition, in order to make the structure of the device more compact, a clearance groove 331 can be provided at the first action end 33, a third through hole 322 corresponding to the clearance groove 331 can be provided on the baffle plate 321, and a fourth through hole 341 corresponding to the third through hole 322 can be provided on the second action end 34. The pull rope 5 passes through the clearance groove 331, the third through hole 322 and the fourth through hole 341 in sequence and is fixed to the bottom end of the second action end 34. At the same time, in order to fix the pull rope 5 and the bottom end of the second action end 34, a receiving hole 342 is provided at the bottom end of the second action end 34, and a wire outlet groove 343 is provided on the side wall of the receiving hole 342. After the pull rope 5 enters the receiving hole 342, it bends toward the wire outlet groove 343. Then, a locking member 344 is provided at the bottom end of the second action end 34 to lock the pull rope 5 at the bottom of the second action end 34. The locking member 344 can be a screw, etc. The threaded end of the screw squeezes the pull rope 5, so that the side wall of the receiving hole 342 and the threaded end of the screw clamp and fix the pull rope 5.
[0059] In order to achieve a better clamping effect of the first clamping plate 21 and the second clamping plate 22, two pull ropes 5 can be provided, and the two pull ropes 5 are symmetrically distributed on both sides of the clamping assembly 2. After passing through the first through hole 123, the two pull ropes 5 converge on the plate surface of the second mounting plate 12 facing the first mounting plate 11, and after merging, they merge into one pull rope 5 and pass through the second through hole 124. In order to ensure that the two pull ropes 5 are not deflected when tightened, a group of guide bars 125 are integrally formed on the top of the second mounting plate 12. The pull ropes 5 are located between the guide bars 125, and the guiding direction of the guide bars 125 faces the second through hole 124, thereby preventing the two pull ropes 5 from deflecting when the two pull ropes are pulled up, thereby ensuring that the tension of the two pull ropes is uniform, which is conducive to the clamping of the ultrasonic probe.
[0060] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
