Both ends of the central shaft 26 are fixedly connected to the synchronous wheel A28. The outer sides of the two driving shafts 18 are fixedly connected to the synchronous wheels B29, and the synchronous wheels A28 and the corresponding synchronous wheels B29 are connected by a synchronous belt 30. Both ends of the outer side of the central shaft 26 are provided with threaded sections 31, and the threaded rotation directions of the two threaded sections 31 are opposite. The tops of the two displacement frames 12 are provided with guide assemblies, which are used to cooperate with the threaded sections 31 to adjust the distance between the two displacement frames 12. It should be noted that the tops of both ends of the assembly frame 11 are fixedly connected with stabilizing seats, and the two ends of the central shaft 26 are rotatably connected to the tops of the two stabilizing seats respectively. The setting of the stabilizing seats can provide auxiliary support for the central shaft 26 to prevent the two ends of the central shaft 26 from shaking; Example 2 like Figure 1 to Figure 9 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes a guiding component; In this embodiment, the guide assembly includes a linkage frame 32, a linkage cylinder 33, a support cylinder 34, a locking plate 35 and a guide screw 36. The top ends of the two displacement frames 12 are fixedly connected to the linkage frame 32, the middle part of the linkage frame 32 is rotatably connected to the linkage cylinder 33, and the two linkage cylinders 33 are respectively threadedly connected to the outer sides of the two threaded segments 31, the top end of the linkage frame 32 is fixedly connected to the support cylinder 34, the inner side of the support cylinder 34 is vertically slidably connected to the locking plate 35, the top end of the support cylinder 34 is threadedly connected to the guide screw 36, and one end of the guide screw 36 located inside the support cylinder 34 is also rotatably connected to the locking plate 35, the bottoms of both ends of the locking plate 35 are fixedly connected to locking rods 37, and the locking rods 37 are also clamped and connected to the linkage cylinder 33; Furthermore, multiple locking holes are provided at both ends of the outer side of the linkage cylinder 33, and the locking rod 37 is snap-connected to the inside of the locking hole.

[0021] A specific application of the above two embodiments is to set the manipulator body 1 in the production area of the flexible circuit board, then start the transmission motor 8 to drive the transmission shaft 3 to rotate, prompting the transmission spur gear 6 to shift the reduction spur gear 7, and then drive the mounting seat 5 to rotate through the support shaft 4, and start the drive motor 10 to drive the adjustment shaft 9 to rotate, and cooperate with the connection between the adjustment shaft 9 and the assembly frame 11, so that the assembly frame 11 follows the adjustment shaft 9 to adjust, thereby changing the adsorption position of the adsorption tube 13; The adsorption tube 13 is adjusted to contact the surface of the flexible circuit board through the manipulator body 1, and then the driving motor 24 is started to drive the driving spur gear A25 to shift the driving spur gear B27, thereby driving the central shaft 26 to rotate, and in conjunction with the setting of two synchronous belts 30, the power at the central shaft 26 can be transmitted to the two driving shafts 18 at the same time, thereby driving the two driving shafts 18 to rotate at the same time. Under the connection between the driving shaft 18 and the transmission screw 19, the transmission screw 19 can be displaced under the transmission of the driving shaft 18, changing the position of the displacement plate 20 inside the transmission cylinder 15. Through the change of the displacement plate 20 inside the transmission cylinder 15, the gas in the adsorption tube 13 can be guided to the inside of the transmission cylinder 15 through the transmission hose 17 and the confluence pipe 16, so as to generate negative pressure at the adsorption tube 13, and finally the flexible circuit board is adsorbed on the adsorption tube 13, and then the flexible circuit board is transferred by the manipulator body 1, so that the loading and unloading of the flexible circuit board can be realized; The guide screw 36 can be rotated, and the connection between the guide screw 36 and the support tube 34 is cooperated, so that the guide screw 36 can drive the locking plate 35 to move under the support of the support tube 34, until the locking rod 37 is engaged with the linkage tube 33, so as to lock the position of the linkage tube 33 and prevent the linkage tube 33 from rotating inside the linkage frame 32. The drive motor 24 is subsequently started to prompt the driving spur gear A25 to shift the driving spur gear B27, thereby driving the central shaft 26 to rotate, and the setting of the threaded sections 31 with opposite thread rotation directions at the two ends of the outer side of the central shaft 26. During the rotation of the central shaft 26, the linkage tube 33 no longer rotates with the threaded sections 31, but moves along the threaded sections 31, thereby adjusting the distance between the two displacement frames 12 to meet the adsorption requirements of flexible circuit boards of different sizes. After the adjustment, the guide screw 36 should be rotated to separate the locking rod 37 from the linkage tube 33. When the threaded section 31 rotates subsequently, the linkage tube 33 can be driven to idle inside the linkage frame 32, so that the displacement frame 12 will not follow the rotation of the threaded section 31 for position adjustment.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
