[0027] It should be noted that the PCB board positioning tooling 6 is determined according to the model characteristics of the PCB board and is not limited to the structure of this embodiment, so it will not be elaborated. Therefore, the PCB board positioning tooling 6 can adopt existing known tooling or fixtures that can be used for PCB board positioning.

[0028] See Figures 1-3 , wherein, four first sliding sleeves 2-11 are fixedly arranged on the bottom surface of the first conveying plate 2-1 and are respectively in sliding fit with two upper guide rods 1-1.

[0029] See Figures 7-8 , in this embodiment, the second conveying unit 3 includes a second conveying plate 3-1, a second rack 3-2, a tray 3-3 and a lifting drive cylinder 3-4; the second rack 3-2 is fixedly connected to the front side wall of the second conveying plate 3-1; the tray 3-3 is located above the second conveying plate 3-1 and is driven by the lifting drive cylinder 3-4 to move up and down; a gear 5 and a power source capable of directly or indirectly driving the gear 5 to rotate are installed on the conveying frame 1; the gear 5 is simultaneously meshed with the first rack 2-2 and the second rack 3-2; in the middle of the upper surface of the tray 3-3, a PCB board positioning tooling 6 is provided.

[0030] Specifically, the first rack 2-2 and the second rack 3-2 are horizontally arranged and distributed up and down, and the gear 5 is located between the first rack 2-2 and the second rack 3-2.

[0031] See Figures 7-8 , in addition, the tray 3-3 is in sliding fit with the second conveying plate 3-1 through a vertical guide rod 3-5; specifically, the upper end of the vertical guide rod 3-5 is fixedly connected to the lower surface of the tray 3-3, and the second conveying plate 3-1 is provided with a guide hole for sliding fit with the vertical guide rod 3-5.

[0033] See Figures 1-3 , in this embodiment, the power source adopts a driving cylinder 4-1; the driving cylinder 4-1 is fixedly installed on the second conveying plate 3-1, and the output end of the driving cylinder 4-1 is fixedly connected to the conveying frame 1.

[0034] Specifically, both the lifting driving cylinder 3-4 and the driving cylinder 4-1 adopt cylinders (i.e., telescopic cylinders).

[0035] See Figures 1-3 , initially, the PCB board positioning tooling on the second conveying unit and the PCB board positioning tooling on the first conveying unit are distributed left and right and at the same height. At this time, the execution mechanism of the chip mounter is located above the PCB board positioning tooling on the first conveying unit and is in position correspondence, and the chip mounter can mount the PCB board placed on the PCB board positioning tooling on the first conveying unit; and when the mounting is completed, then start the integrated circuit conveying switching device to perform the conveying switching work as follows:

[0036] S10. First, start the lifting driving cylinder 3-4 on the second conveying unit 3 to work. The lifting driving cylinder 3-4 drives the tray 3-3 to descend and reach the position. At this time, the PCB board positioning tooling on the second conveying unit and the PCB board positioning tooling on the first conveying unit remain distributed left and right, but the PCB board positioning tooling on the second conveying unit has descended to the low position (see Figures 9-11 );

[0037] S20. Then, start the power source on the second conveying unit 3 to work. The power source directly or indirectly drives the gear 5 to rotate counterclockwise. The gear 5 drives the first rack 2-2 and the second rack 3-2 to move symmetrically in the opposite direction and reach the position. At this time, the PCB board positioning tooling on the second conveying unit and the PCB board positioning tooling on the first conveying unit are switched to be distributed right and left, and the PCB board positioning tooling on the second conveying unit is still in the low position (see Figures 12-14 );

[0038] S30. Then, start the lifting driving cylinder 3-4 on the second conveying unit 3 to work. The lifting driving cylinder 3-4 drives the tray 3-3 to ascend and reach the position. At this time, the PCB board positioning tooling on the second conveying unit and the PCB board positioning tooling on the first conveying unit are distributed right and left, and the PCB board positioning tooling on the second conveying unit ascends to the position and is at the same height left and right. At this time, the PCB board (not shown in the figure) on the PCB board positioning tooling on the second conveying unit also corresponds to the position of the execution mechanism of the chip mounter (see Figures 15-17 );

[0039] S40. The mounter mounts the PCB board positioned and placed on the PCB board positioning fixture of its second conveying unit.

[0040] S50. After the mounting is completed, the return movement is started again and it returns to the initial state, and the conveying and station switching are completed again. At this time, the PCB board positioning fixtures on the second conveying unit and the PCB board positioning fixture on the first conveying unit are distributed left and right and at the same height (i.e., the initial state, see Figures 1-3 ). At this time, the actuator of the mounter is located above the PCB board positioning fixture on the first conveying unit and in corresponding positions, and the mounter can mount the next PCB board positioned and placed on the PCB board positioning fixture on the first conveying unit again.

[0041] In this embodiment, during the process of the actuator of the mounter mounting the PCB board on the PCB board positioning fixture on the first conveying unit, the already-mounted PCB board on the PCB board positioning fixture on the second conveying unit can be unloaded first and then the next PCB board to be mounted can be placed (manual or automatic operation by a manipulator) simultaneously. When the mounting of the PCB board on the first conveying unit is completed, the next PCB board to be mounted has been positioned and placed on the PCB board positioning fixture on the second conveying unit; then the above-mentioned conveying and switching work (double-station left-right switching) is started; then, during the process of the actuator of the mounter mounting the PCB board on the PCB board positioning fixture on the second conveying unit, similarly, the already-mounted PCB board on the PCB board positioning fixture on the first conveying unit can be unloaded first and then the next PCB board to be mounted can be placed (manual or automatic loading and unloading by a manipulator). When the mounting of the PCB board on the second conveying unit is completed, the next PCB board to be mounted has been positioned and placed on the PCB board positioning fixture on the first conveying unit; then the above-mentioned conveying and switching work is started again and so on in a cycle.

[0042] This embodiment can achieve double-station automatic conveying and switching between the first conveying unit and the second conveying unit and can be completed in a very short time (3 - 5 s); at the same time, during the process of unloading the already-mounted PCB board from the PCB board positioning fixture and placing the PCB board to be mounted on the PCB board positioning fixture, it will not affect the mounting work of the mounter, they do not interfere with each other, and the mounter will not be interrupted during workpiece loading and unloading, thus improving production efficiency.

[0043] In this embodiment, the power source uses the telescopic movement of the output end of the driving cylinder to drive the second conveying plate 3-1 and the second rack 3-2 to displace and slide relative to the conveying frame 1. The second rack 3-2 will drive the first rack 2-2 to move through the gear 5, and then the first conveying plate 3-1 will displace and slide relative to the conveying frame 1. By controlling the reverse and symmetric movement of the second rack 3-2 and the first rack 2-2 through the gear 5, the left-right relative switching displacement of the second conveying plate 3-1 and the first conveying plate 2-1 is realized.

[0044] Embodiment 2: This embodiment is basically the same as Embodiment 1, except that:

[0045] See Figure 8 , in this embodiment, the power source uses the motor 4-2; the motor 4-2 is installed on the conveying frame 1, and the output end of the motor 4-2 is coaxially connected to the gear 5. Therefore, the motor 4-2 can directly drive the gear 5 to rotate, and the gear 5 controls the reverse and symmetric movement of the first rack 2-2 and the second rack 3-2, thereby realizing the left-right relative switching displacement of the second conveying plate 3-1 and the first conveying plate 2-1. The above has described in detail the preferred specific embodiments of the present invention. It should be understood that those of ordinary skill in the art can make many modifications and changes based on the concept of the present invention without creative labor. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field of the present invention through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the prior art should be within the protection scope determined by the claims.
