Detailed implementation mode

[0023] The technical solutions in the embodiments of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention:

[0024] As Figure 1-2 shown, a double-mover linkage three-axis grasping mechanism based on a magnetic drive conveying system mainly consists of a guide rail 1, a first mover 11, a second mover 12, a drive adapter mounting 2, a connecting plate 3 and a grasping unit. The guide rail 1 includes a straight section and an arc section, and the first mover 11 and the second mover 12 are slidably mounted on the guide rail 1 through pulleys.

[0025] When the first mover 11 and the second mover 12 are located on the straight section of the guide rail 1, the drive adapter mounting 2 is fixedly mounted on the side of the first mover 11 away from the guide rail 1. It is fixedly connected to the first mover 11 through an L-shaped plate. And the inner side of the drive adapter mounting 2 is provided with a track one 21, and the outer side is provided with a rack one 23 and a rack two 24. The second mover 12 is slidably mounted on the track one 21 through the connecting plate 3. A slider 211 is slidably mounted on the track one 21. The side of the slider 211 away from the track one 21 is fixedly connected to the connecting plate 3. At the same time, a guide groove 22 is opened on the outer side of the drive adapter mounting 2. The guide groove 22 includes an uphill section and two horizontal sections, and the two horizontal sections are arranged at both ends of the uphill section.

[0026] As Figure 3-6As shown, the grasping unit is arranged at one end of the connecting plate 3 away from the track 21, and it includes a rod-bearing one 4, an adapter 41 and a mounting seat 42 which are connected in sequence. Among them, the rod-bearing one 4 is slidably mounted in the guide groove 22 to form a moving pair. When the first mover 11 and the second mover 12 generate relative displacement, the grasping unit can also move relatively with the driving adapter mounting member 2. A gear shaft one 43 is arranged through the mounting seat 42. The gear shaft one 43 meshes with the rack one 23. And a pinion 44 is provided at the bottom end of the gear shaft one 43. The two sides of the pinion 44 are meshed and connected with a grasping slide 45. A small rack 451 meshing with the pinion 44 is mounted on the grasping slide 45. A pair of tracks two 421 are mounted at the bottom of the mounting seat 42. Two sliding seats 422 are provided on the track 421. The bottoms of the two sliding seats 422 are respectively connected with the grasping slides 45 on both sides. When the gear shaft one 43 rotates, it drives the pinion 44 to rotate synchronously, thereby driving the relative movement of the small rack 451, and further realizing the approaching / separating movement of the grasping slide 45. The adapter 41 includes a fixed seat 411, a connecting seat 412 and a rotating plate 413 which are connected in sequence. A gear shaft two 414 is arranged through the connecting seat 412. The gear shaft two 414 meshes with the rack two 24. The lower end of the gear shaft two 414 is connected with the rotating plate 413 through a bearing 415. A connecting rod 416 is provided between the rotating plate 413 and the mounting seat 42. When the gear shaft two 414 rotates, it can drive the whole below to rotate. A pair of guiding bearings 417 are provided on both sides of the top end of the fixed seat 411. A lifting guide rod 418 is slidably inserted into the guiding bearings 417 to form a guiding pair. The top end of the lifting guide rod 418 is fixedly connected with the connecting plate 3. When the grasping unit approaches the second mover 12, the guiding bearings 417 move rightward in the guide groove 22, and drive the grasping unit to lift when passing through the uphill section.

[0027] A limiting member 5 is provided above the gear shaft one 43, such as Figure 7As shown in the figure, the limiting member 5 includes a guide rod 51 and a limiting seat 52. One end of the guide rod 51 is sleeved with a spring 511, and a rod-bearing two 53 is installed at the other end. A through groove 521 matching the guide rod 51 is formed on the limiting seat 52. The free end of the spring 511 is connected to the inner wall of the through groove 521. A guide bar 231 is provided on the first rack 23. The rod-bearing two 53 contacts the outer side surface of the guide bar 231. A limit pin 54 is provided on the guide rod 51. The lower end of the limit pin 54 slides through the limiting seat 52, and a channel for the movement of the limit pin 54 is formed on the limiting seat 52. A limit groove 431 matching the limit pin 54 is provided on the first gear shaft 43. In the initial state, the rod-bearing two 53 contacts the guide bar 231, driving the guide rail 51 to move into the through groove 521 and compress the spring 511. The limit pin 54 is located inside the first gear shaft 43. When the first gear shaft 43 is about to disengage from the first rack 23, the rod-bearing two 53 moves upward to disengage from the guide bar 231, and the guide rod 51 moves outward under the reaction force of the spring 511, thereby driving the limit pin 54 to snap into the limit groove 431 to lock the first gear shaft 43. When the first gear shaft 43 is about to mesh with the first rack 23, the rod-bearing two 53 contacts the guide bar 231 again, driving the guide rail 51 to move into the through groove 521, and the limit pin 54 disengages from the limit groove 431 accordingly, avoiding the phenomenon of gear collision.

[0028] To further improve the transfer stability, a limiting member 5 can be provided above the second gear shaft 414. At the same time, a limit groove is formed on the second gear shaft 414, and a guide bar is provided on the second rack 24 to cooperate with the limiting member 5 for operation.

[0029] When the first mover 11 and the second mover 12 are located on the arc section of the guide rail 1, a dislocation occurs between the first mover 11 and the second mover 12. A rotating shaft unit needs to be provided between the first mover 11 and the driving transfer mounting member 2, and between the second mover 12 and the connecting plate 3 to realize the distance adjustment of the first mover 11 and the second mover 12 passing through the arc section, as Figure 8 shown. The rotating shaft unit includes a rotating shaft 6 and a bolt 61. Connecting holes 62 are respectively formed on the first mover 11 and the second mover 12. One end of the rotating shaft 6 is rotatably installed in the connecting hole 62 through a bearing seat, and the other end is fixedly connected to the driving transfer mounting member 2 and the connecting plate 3 through bolts 61 respectively, so that when the first mover 11 and the second mover 12 pass through the arc section, the driving transfer mounting member 2, the connecting plate 3 and the grasping unit below can rotate relative to the mover to prevent the mechanism from jamming.

[0030] The above embodiments are only a part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
