Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be completely conveyed to those skilled in the art.
[0023] Such as Figures 1 to 8As shown in the figure, a device picking and placing mechanism includes an X-direction guiding block 1, an X-direction sliding block 2, an L-shaped seat 3, a connecting plate 4 and a handle 5. A linear guide rail is provided on the side of the X-direction guiding block 1. The X-direction sliding block 2 is slidably matched with the linear guide rail. The L-shaped seat 3 is fixedly connected to the X-direction sliding block 2. The connecting plate 4 is rotatably connected to the L-shaped seat 3 through a rotating shaft 6. A handle 5 is installed at one end of the connecting plate 4, and a long circular hole 7 is provided at the other end. A Y-direction guiding block 8 is installed on the L-shaped seat 3. A linear guide rail is provided on the side of the Y-direction guiding block 8. A Y-direction sliding block 9 is slidably matched with this linear guide rail. The Y-direction sliding block 9 is fixed on a bracket 10. A connecting rod 11 is connected to the bracket 10. A suction nozzle 12 is installed at the end of the connecting rod 11. A pin 13 is installed on the bracket 10, and one end of the pin 13 extends into the long circular hole 7 on the connecting plate 4.
[0024] In this embodiment, a handle seat 14 is detachably installed at the end of the connecting plate 4. A limiting groove 15 is provided on the top surface of the handle seat 14. A first limiting column is provided at the bottom of the handle 5. The first limiting column is fitted in the limiting groove 15, and the handle 5 is detachably connected to the handle seat 14.
[0025] In this embodiment, a limiting plate 16 is detachably installed on the bracket 10. A second limiting column 17 is provided on the bottom surface of the limiting plate 16. A limiting hole 18 is provided on the top surface of the X-direction guiding block 1. The second limiting column 17 is fitted in the limiting hole 18. Three limiting holes 18 are provided on the top surface of the X-direction guiding block 1, so as to conveniently position the suction nozzle 12 to three specified positions, that is, the initial position, the device suction position and the device placement position.
[0026] In this embodiment, a micro switch 19 is installed on the X-direction guiding block 1 corresponding to the limiting hole 18. The position of the suction nozzle is further accurately confirmed through the micro switch 19.
[0027] In this embodiment, a limiting block 20 is provided at the top of the Y-direction guiding block 8. The upward movement of the bracket 10 out of the linear guide rail is avoided through the limiting block 20.
[0028] In this embodiment, a wire trough drag chain 21 is installed outside the L-shaped seat 3.
[0029] In this embodiment, a positioning part 22 is installed on the bottom surface at the end of the connecting rod 11. A connecting column 23 is provided on the top of the suction nozzle 12. A long circular hole 24 is opened on the connecting column 23. The connecting column 23 and the positioning part 22 are installed on the connecting rod 11 through a connecting pin, and the connecting pin passes through the long circular hole 24. A spring 25 is sleeved on the connecting column 23 between the positioning part 22 and the suction nozzle 12.
[0030] Both ends of the connecting rod 11 are provided with air holes, and an air supply channel connecting the air holes is arranged inside the connecting rod 11. A connector 26 is installed on one of the air holes and connected to an air source through a pipeline, and a suction nozzle 12 is installed on the other air hole. A conical groove is provided on the bottom surface of the suction nozzle 12 to facilitate sucking and fastening the device. A control button 27 is installed on the handle 5 to control the opening or closing of the suction nozzle 12.
[0031] During use, press down the handle 5, so that the connecting plate 4 rotates around the rotating shaft 6 as the axis, and the other end of the connecting plate 4 is lifted upward. By cooperating with the long circular hole 7 on the connecting plate 4 through the pin 13, the bracket 10 is driven to move upward in the vertical direction. The Y-direction slider 9 plays a guiding role. At the same time, the limiting plate 16 moves upward, so that the second limiting column 17 moves out of the limiting hole 18. Then, push the L-shaped seat 3 forward along the X-direction guiding block 1 through the handle 5. When moving to the position for sucking the device, put down the handle 5, the bracket 10 moves downward, and the second limiting column 17 is inserted into the limiting hole 18. At the same time, the bottom surface of the limiting plate 16 touches the microswitch 19, and the suction nozzle 12 is controlled to work through the control button 27 on the handle 5 to suck the device; press down the handle 5 again, the bracket 10 drives the limiting plate 16 to move upward, and the second limiting column 17 moves out of the limiting hole 18; continue to push the L-shaped seat 3 forward along the X-direction guiding block 1 through the handle 5. When moving to the position for placing the device, put down the handle 5, the bracket 10 moves downward, the second limiting column 17 is inserted into the limiting hole 18, and at the same time, the bottom surface of the limiting plate 16 touches the microswitch 19. The control button 27 on the handle 5 controls the suction nozzle 12 to close, and the device loses the suction force of the suction nozzle and falls to the designated position.
