Positioning frame 4 is composed of a first plate, a second plate and a third plate. The first ends of the first plate and the third plate are respectively fixed on the two ends of the first side of the second plate. The first plate and the second plate are arranged parallel to each other. The second plate is provided with a first slot 5 connecting the top surface and the bottom surface of the second plate. The first slot 5 is composed of eleven linearly arranged first through holes and ten first channels. Two adjacent first through holes are connected by a first channel. The width of the first channel is smaller than the diameter of the first through hole. An elastic layer is provided on the inner wall of the first slot 5. Positioning frame 4 is connected to the rotating part of the rotating mechanism. The rotating mechanism is used to perform a flipping operation on positioning frame 4. Four first rectangular rings 6; the first side of one first rectangular ring 6 is disposed in a first through hole and presses against the elastic layer of the first slot 5, and its second side is disposed outside the first side of the second plate. The first rectangular ring 6 can be moved by external force and under the deformation of the elastic layer from one first through hole to another first through hole through a first channel. The propulsion mechanism is connected to the second end of the first plate and the second end of the third plate respectively at both ends. The propulsion end of the propulsion mechanism is provided with a push plate 12 that is parallel to the second plate. The first side of the push plate 12 faces the first side of the second plate, and the pushing direction of the propulsion end points to the second plate. The push plate 12 is provided with a second slot 11 that connects the top and bottom surfaces of the push plate 12. The second slot 11 is composed of eleven linearly arranged second through holes and ten second channels. Two adjacent second through holes are connected by a second channel.

[0016] Example 2 The difference between this embodiment and Embodiment 1 is that, as Figure 2 As shown, the lifting tray includes: The slide rail and the slider are fixedly laid on the base plate 1. The slide rail is set between the projections of the first plate and the second plate on the base plate 1 and is parallel to the projections of the first plate and the second plate. The slider is slidably set on the slide rail. First telescopic motor 16; First telescopic motor 16 is connected to drive module, first telescopic motor 16 is fixedly mounted on slider, and telescopic rod of first telescopic motor 16 is set vertically upward; Disc 15; Disc 15 is horizontally positioned on the end face of the telescopic rod of the first telescopic motor 16.

[0017] In this embodiment, after the circuit board 7 is raised to a preset height by the first telescopic motor 16, the operator can manually push the slider so that one side of the circuit board 7 on the disc 15 contacts the first rectangular ring 6. Then, the pusher plate 12 is pushed by the pusher mechanism so that the second rectangular ring 8 and the second side of the first rectangular ring 6 are pressed into contact with the two sides of the circuit board 7 respectively, so as to fix the circuit boards 7 of different sizes.

[0018] Example 3 The difference between this embodiment and Embodiment 1 is that, as Figure 1 , Figure 2 As shown, the rotating mechanism includes: Fixing plate 2; Fixing plate 2 is vertically mounted on base plate 1; Motor mount 10; Motor mount 10 is fixedly mounted on base plate 1; Drive motor 9; Drive motor 9 is fixedly mounted on motor base 10. Drive motor 9 is connected to control module. The shaft of drive motor 9 is horizontally set and fixedly inserted into the outer side of the third plate. Connecting shaft 3; one end of connecting shaft 3 is fixedly connected to fixed plate 2, and connecting shaft 3 and the rotating shaft of drive motor 9 are on the same horizontal line; Bearing; the outer side of the first plate is provided with a blind hole, the outer ring of the bearing is fixedly connected to the inner wall of the blind hole, and the second end of the connecting shaft 3 is inserted into the inner ring of the bearing and fixedly connected to the inner ring of the bearing.

[0019] Example 4 The difference between this embodiment and Embodiment 1 is that, as Figure 1 , Figure 2 and Figure 3 As shown, the propulsion mechanism includes: First cover plate 14; two mounting strips are provided on both sides of the bottom surface of the first cover plate 14, and the two mounting strips of the first cover plate 14 are fixedly connected to the top surface of the second end of the first plate and the top surface of the second end of the third plate, respectively. The second cover plate has two mounting strips on both sides of its top surface. The two mounting strips of the second cover plate are fixedly connected to the bottom surface of the second end of the first plate and the bottom surface of the second end of the third plate, respectively. The second telescopic motor 13 is connected to the control module. The second telescopic motor 13 is fixedly mounted between the first cover plate 14 and the second cover plate. The telescopic rod of the second telescopic motor 13 is set towards the second plate and is fixedly connected to the push plate 12.

[0020] Example 5 The difference between this embodiment and embodiment 1 is that the material of the side of the first rectangular ring 6 and the second rectangular ring 8 that contacts the circuit board 7 is rubber. The rubber material can provide a certain buffer when the circuit board 7 is squeezed and contacted to avoid damage.

[0021] Example 6 The difference between this embodiment and Embodiment 1 is that the elastic layer is made of rubber. In this application, the cross-section of the first side of the first rectangular ring 6 and the second rectangular ring 8 is circular. The diameter of the first side of the first rectangular ring 6 and the second rectangular ring 8 is smaller than the width of the first channel and the second channel, respectively. However, the spacing between the elastic layers on the two side walls of the first slot 5 / second slot 11 is smaller than the diameter of the first side of the first rectangular ring 6 / second rectangular ring 8, so that the first rectangular ring 6 / second rectangular ring 8 are always in a state of compression contact. For example... Figure 5 As shown in the figure, the shaded area is the elastic layer of the first slot 5. When the first rectangular ring 6 is in the first through hole, it is pressed and contacted with the elastic layer in the first through hole. When the operator moves the first rectangular ring 6 to another first through hole, the first rectangular ring 6 presses the elastic layer in the first channel to deform it so that the first rectangular ring 6 can pass through.

[0022] Example 7 The difference between this embodiment and Embodiment 1 is that, as Figure 4As shown, each of the two sides of the second side of the first rectangular ring 6 and the second rectangular ring 8 is provided with a locking block 17. The locking block 17 contacts the first side of the second plate or the first side of the push plate 12. The locking block 17 can prevent the first rectangular ring 6 and the second rectangular ring 8 from rotating about their own first side as the axis of rotation.
