[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] The utility model provides a multifunctional integrated placement machine for PCBA production, such as Figure 1 、 Figure 2 and Figure 3As shown, the placement machine includes a base plate 1, a work frame 2 fixedly mounted on the base plate 1, a placement box 10 arranged on the work frame 2, a circuit board 15 arranged inside the placement box 10, a rotating shaft 11 fixedly mounted on the placement box 10, and a support block 7 fixedly mounted on the work frame 2, a rotating groove is opened on the support block 7, the rotating shaft 11 is inserted into the rotating groove, a mounting plate 3 is fixedly connected to the work frame 2, a servo motor 4 is fixedly connected to the mounting plate 3, and an output end of the servo motor 4 is fixedly connected to the end of the rotating shaft 11 away from the placement box 10.

[0026] When the placement machine is working, the circuit board 15 needs to be placed inside the placement box 10. After the components on one side of the circuit board 15 are placed, the servo motor 4 can be started to drive the placement box 10 to flip 180 degrees on the spot through the rotating shaft 11, thereby facilitating the placement of components on the other side of the circuit board 15. The setting of the support block 7 is used to support the placement box 10 on the one hand, and to improve the stability of the rotating shaft 11 during rotation on the other hand.

[0027] Furthermore, in order to reduce the possibility of the circuit board 15 being damaged by compression, as Figure 1 、 Figure 2 and Figure 4 As shown, the interior of the mounting box 10 is fixedly connected to an insertion rod 12, and a first buffer frame 14 is movably connected to the insertion rod 12. A first spring 13 is sleeved on the insertion rod 12, and one end of the first spring 13 is fixedly connected to the mounting box 10, and the other end of the first spring 13 is fixedly connected to the first buffer frame 14. The circuit board 15 is movably connected to the insertion rod 12, and the circuit board 15 is in contact with the side of the first buffer frame 14 away from the first spring 13.

[0028] A second buffer frame 16 is movably connected to the insertion rod 12, and one side of the second buffer frame 16 is in contact with the side of the circuit board 15 away from the first buffer frame 14. A limiting rod 17 is fixedly connected to the second buffer frame 16, and a mounting frame 19 is movably connected to the limiting rod 17. A second spring 18 is provided between the mounting frame 19 and the second buffer frame 16, and both ends of the second spring 18 are fixedly connected to the mounting frame 19 and the second buffer frame 16 respectively. The second spring 18 is sleeved on the insertion rod 12, and the side of the mounting frame 19 close to the second spring 18 is in contact with the end of the insertion rod 12 away from the mounting box 10.

[0029] The first buffer frame 14 is in a fixed state relative to the mounting box 10 and cannot be removed from the mounting box 10. The second buffer frame 16, the second spring 18 and the mounting frame 19 are a separate whole. The upper limit rod 17 on the second buffer frame 16 is set to prevent the second buffer frame 16 from detaching from the mounting frame 19. When the circuit board 15 is installed in the mounting box 10, it is necessary to let the insertion rod 12 pass through the notch on the circuit board 15 to fix the circuit board 15. Then, the second buffer frame 16, the second spring 18 and the mounting frame 19 are installed inside the mounting box 10, and the insertion rod 12 passes through the second buffer frame 16 and the second spring 18. At this time, the first buffer frame 14 and the second buffer frame 16 are respectively fitted with the two sides of the circuit board 15. When components are mounted on the circuit board 15, the first buffer frame 14 and the second buffer frame 16 can provide buffering for the circuit board 15 through the first spring 13 and the second spring 18, reducing the possibility of the circuit board 15 being squeezed and damaged.

[0030] In order to improve the stability of the mounting frame 19 during operation, Figure 2 、 Figure 4 and Figure 5 As shown, a limiting shell 20 is fixedly connected to the mounting box 10, and a clamping block 21 is slidably connected inside the limiting shell 20. The clamping block 21 fits with the side of the mounting frame 19 away from the insertion rod 12. A third spring 23 is provided inside the limiting shell 20, and one end of the third spring 23 is fixedly connected to the clamping block 21, and the other end of the third spring 23 is fixedly connected to the limiting shell 20. A shifting block 22 that passes through the limiting shell 20 is fixedly connected to the clamping block 21, and a sliding groove for the shifting block 22 to slide is provided on the limiting shell 20.

[0031] A notch is provided on the second buffer frame 16. When the second buffer frame 16 and the mounting frame 19 are mounted inside the mounting box 10, the second buffer frame 16 will not contact the block 21, and the mounting frame 19 will squeeze the block 21, forcing the block 21 and the third spring 23 to shrink toward the inside of the limiting shell 20. When the mounting frame 19 is completely installed inside the mounting box 10, the block 21 can be quickly popped out by the force of the third spring 23, fixing the mounting frame 19 inside the mounting box 10.

[0032] It should be noted that in order to improve the stability of the mounting box 10 during operation, Figure 1 and Figure 3 As shown, an electric push rod 5 is fixedly connected to the bottom plate 1 , and a support plate 6 for supporting the mounting box 10 is fixedly connected to the movable end of the electric push rod 5 .

[0033] The mounting box 10 can be turned 180 degrees in situ with the circuit board 15. By controlling the electric push rod 5, the electric push rod 5 pushes the support plate 6 so that the support plate 6 is close to the mounting box 10, which can improve the stability of the mounting box 10. When the mounting box 10 needs to be turned over, the electric push rod 5 can be controlled to drive the support plate 6 to move downward to provide space for the mounting box 10 to turn over. There are two electric push rods 5, and they work synchronously. This setting can fully improve the stability of the support plate 6 during movement and work, so that the support plate 6 can better serve the mounting box 10.

[0034] Furthermore, in order to realize the mounting of components on the circuit board 15, as shown in FIG. Figure 1 and Figure 3 As shown, a mounting frame 8 is fixedly connected to the work frame 2 , and a placement arm 9 for placing components on the circuit board 15 is fixedly connected to the mounting frame 8 .

[0035] By connecting the placement hand 9 via an external control terminal, the placement hand 9 can be controlled to extend, retract and rotate, thereby enabling the placement hand 9 to place components at corresponding positions on the circuit board 15 .

[0036] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
