the transmission member 430 causes the top block 420 to rotate in the third circumferential direction when the needle 200 moves in the first axial direction away from the robot arm 300, the transmission member 430 causes the top block 420 to rotate in the fourth circumferential direction when the needle 200 moves in the first axial direction toward the robot arm 300, and causes the top block 420 to move in the radial direction of the needle 200 toward the needle 200, and the displacement of the top block 420 to move toward the needle 200 is larger than the displacement of the top block 420 to rotate in the fourth circumferential direction away from the needle 200. The first axial direction is the vertical direction in fig. 2, the second axial direction is the tangential direction of the flying probe 200, and the second axial direction is perpendicular to the first axial direction.
In this embodiment, the mounting assembly 400 further includes a connecting member 440, the connecting member 440 is located in the sleeve 410, the mounting end of the flying probe 200 is fixedly connected with the connecting member 440, and the connecting member 440 abuts against the mechanical arm 300; a plurality of transmission parts 430, each transmission part 430 including a first rack 431, a second rack 432, a third rack 433, a first gear 434, and a second gear 435; the first rack 431, the second rack 432 and the third rack 433 are all arranged along the first axial direction, the first rack 431 can be slidably mounted on the connecting piece 440 along the radial direction of the flying probe 200, and a compression spring (not shown in the figure) is arranged between the first rack 431 and the connecting piece 440, and the compression spring urges the first rack 431 to be far away from the connecting piece 440; the second rack 432 is fixed to the sleeve 410, and the first gear 434 is rotatably installed between the first rack 431 and the second rack 432 around the second axis and is engaged with the first rack 431 and the second rack 432, respectively; the top block 420 is fixedly connected with the first gear 434; the second gear 435 is fixedly connected with the first gear 434 and is coaxial with the first gear 434; the third rack 433 is slidably mounted on the sleeve 410 along the first axial direction, and the third rack 433 is in frictional contact with the sleeve 410; an elastic element 436 is arranged between the third rack 433 and the sleeve 410, and the elastic element 436 causes the third rack 433 to move away from the mechanical arm 300; the third rack 433 comprises a tooth part and a plate part, the plate part is positioned at one side of the tooth part far away from the mechanical arm 300, teeth of the third rack 433 are distributed on the plate part, and the teeth extend along the radial direction of the flying probe 200; the width of the tooth portion of the third rack 433 in the radial direction of the flying needle 200 is gradually increased along the first axial direction toward the mechanical arm 300, so that when the second gear 435 moves along the third rack 433 toward the mechanical arm 300, the displacement of the second gear 435 in the direction toward the flying needle 200 is greater than the displacement of the top block 420 away from the flying needle 200 when the second gear 435 rotates along the fourth circumferential direction; in the initial state, the second gear 435 is in contact with the plate portion of the third rack 433, and the third rack 433 makes the teeth of the teeth portion in contact with the side of the second gear 435, which is close to the mechanical arm 300, under the action of the elastic member 436.
During installation, the flying probe 200 is manually fixed, and the sleeve 410 is pushed along the first axial direction towards the direction approaching the mechanical arm 300; when the sleeve 410 drives the second rack 432 to move towards the direction approaching the mechanical arm 300 relative to the flying probe 200 along the first axial direction, the second rack 432 drives the first gear 434 to rotate along the third circumferential direction and enable the first gear 434 to move towards the direction approaching the mechanical arm 300, the second gear 435 rotates along the third circumferential direction along with the first gear 434 and pushes the third rack 433 to move towards the direction approaching the mechanical arm 300 when moving towards the direction approaching the mechanical arm 300, meanwhile, the sleeve 410 drives the third rack 433 to synchronously move towards the direction approaching the mechanical arm 300 through the elastic piece 436, so that the second gear 435 is kept in abutting connection with a plate part of the third rack 433, and teeth of the third rack 433 are kept in abutting connection with one side, approaching the mechanical arm 300, of the second gear 435.

When the flying needle 200 is moved along the first axial direction to the direction away from the mechanical arm 300, the flying needle 200 drives the first rack 431 to move along the direction away from the mechanical arm 300 relative to the second rack 432, and further drives the first gear 434 to rotate along the third circumferential direction and move along the direction close to the mechanical arm 300, so that the top block 420 is further abutted against the flying needle 200, the pushing force of the top block 420 on the flying needle 200 is increased, and the flying needle 200 is prevented from further moving along the direction away from the mechanical arm 300; if the flying probe 200 moves along the first axial direction toward the direction approaching the mechanical arm 300, the flying probe 200 drives the first rack 431 to move toward the direction approaching the mechanical arm 300 relative to the second rack 432, so as to drive the first gear 434 to rotate along the fourth circumferential direction and move toward the direction approaching the mechanical arm 300, the second gear 435 is meshed with the tooth portion of the third rack 433 when the second gear 435 rotates along the fourth circumferential direction and moves toward the direction approaching the mechanical arm 300 along with the first gear 434, and the meshing position of the second gear 435 and the third rack 433 moves toward the direction approaching the mechanical arm 300, so that the pushing of the third rack 433 of the second gear 435 moves along the direction approaching the flying probe 200, and drives the first gear 434 and the top block 420 to move toward the direction approaching the flying probe 200, and simultaneously presses the first rack 431 toward the direction approaching the flying probe 200, the distance between the top block 420 and the flying probe 200 is reduced, and the pushing force of the top block 420 to the flying probe 200 is further increased; the third rack 433 further abuts against the inner wall of the sleeve 410 under the pressing of the second gear 435 along the radial direction of the flying needle 200 while the ejector block 420 abuts against the flying needle 200, so that the friction between the third rack 433 and the sleeve 410 is increased, and the third rack 433 is prevented from moving under the action of the elastic member 436.
In the present embodiment, there are two second gears 435 of each transmission part 430, the two second gears 435 are respectively located at two sides of the first gear 434 along the second axis, and the diameter of the second gear 435 is larger than that of the first gear 434; the second rack 432 is located between the two second gears 435, and the second rack 432 is engaged with the first gear 434 while restricting movement of the two second gears 435 in the second axis. The larger the diameter of the second gear 435 is different from the diameter of the first gear 434, the larger the displacement of the third rack 433 moving under the transmission of the second gear 435 when the second gear 435 rotates by the same angle with the first gear 434, the larger the displacement of the second gear 435 moving toward the flying needle 200 under the pushing of the third rack 433 when the second gear 435 moves toward the direction approaching the mechanical arm 300 relative to the third rack 433, and thus the faster the ejector block 420 pushes against the flying needle 200.
