At the moment, a gap is reserved between the PCB (14) and the feeding belt assembly (7), and the assembly line can also perform feeding action. The two actions interfere complementarily.

When the PCB top plate (5) does not work, and the assembly line works (as shown in figure 6), the PCB top plate (5) descends to the lower part of the feeding belt component (7), the limiting block (6) limits the descending distance of the PCB top plate (5), and the feeding belt component (7) drives the PCB (14) to move.

The working principle and the process of the product are as follows:

firstly, dividing a chip mounter assembly line into three areas: the PCB processing system comprises a PCB waiting area (A), a PCB working area (B) and a PCB discharging area (C). Each zone has a photosensor: waiting for a photoelectric sensor (16), a working photoelectric sensor (17) and a board-out photoelectric sensor (18), wherein the photoelectric sensor is at a high level and indicates that a PCB is available, and the photoelectric sensor is at a low level and indicates that no PCB is available.

The chip mounter sends a signal for the PCB, the PCB (14) flows into a working area of the chip mounter,

feeding motor (8) drive feeding belt subassembly (7) and flow, take first PCB board (14) toward PCB waiting area, at this in-process, wait for photoelectric sensor (16) in the PCB workspace and be in the low level, host computer software judges that the PCB workspace does not have PCB board (14), the chip mounter is not working, so first PCB board (14) do not wait in PCB waiting area, direct flow to PCB workspace under the drive of feeding belt subassembly (7).

When the first PCB (14) reaches the PCB working area, the working photoelectric sensor (17) of the PCB working area is switched from low level to high level, the upper computer software detects a signal, the feeding motor (8) stops rotating, and therefore the feeding belt assembly (7) stops flowing.

Cylinder (1) is aerifyd, the cylinder ejector pin stretches out, drive ejector pin (2) horizontal motion, ejector pin (2) drive connecting rod (3) motion, it uses a rotatory hole of assembly line seat (41) to rotate as the center to drive and sways piece (4), it rotates to drive and sways piece (4), it sways a rotatory hole of PCB roof (42) on piece (4) to sway, use and sway a rotatory hole of assembly line seat (41) and rotate as the center, thereby drive PCB roof (5) upward movement. The first PCB (14) is separated from the feeding belt component (7) and moves upwards together, so that the first PCB (14) is fixed between the PCB pressing block (11) and the PCB top plate (5). At this time, the chip mounter works.

When the chip mounter works, waiting photoelectric sensor (16) in the PCB waiting area is at low level, the host computer judges that the PCB waiting area does not have PCB board (14), the chip mounter sends out and wants PCB board signal, second PCB board (14) flow into chip mounter work area, feeding motor (8) drive feeding belt subassembly (7) and flow, second PCB board (14) are taken toward the PCB waiting area, in this process, working photoelectric sensor (17) of PCB work area are at high level, host computer software judges that the PCB work area has first PCB board (14), and the chip mounter has work, feeding belt subassembly (7) take second PCB board (14) to the PCB waiting area, waiting photoelectric sensor (16) of PCB waiting area is switched to high level by low level, feeding motor (8) stop rotating, thereby feeding belt subassembly (7) stop flowing. The second PCB board (14) waits for the completion of the work of the first PCB board (14) in the waiting area.

When first PCB board (14) work is accomplished, cylinder (1) gassing, through a series of connecting rod actions, PCB roof (5) descend, and first PCB board (14) also along with descending, again with feeding belt subassembly (7) contact, feeding motor (8) drive feeding belt subassembly (7) flow after that, two actions take place simultaneously this moment: 1. a first PCB (14) of the PCB working area is transmitted to a discharging belt, and a working photoelectric sensor (17) of the PCB working area is switched from a high level to a low level; 2. a second PCB board (14) of the PCB waiting area is transferred to the PCB working area, and a waiting photoelectric sensor (16) of the PCB waiting area is switched from a high level to a low level.

Ejection of compact motor (10) rotate and drive ejection of compact belt subassembly (9) and flow, first PCB board (14) flow to ejection of compact belt subassembly (9) from feeding belt subassembly (7) above, ejection of compact belt subassembly (9) take first PCB board (14) to stay PCB out of the board district, PCB out of the board photoelectric sensor (18) of board district switch to the high level by the low level, host computer software judges that PCB out of the board district has first PCB board (14), host computer software, if receive the signal that next stage equipment prepared, direct transfer to next stage equipment, if not received, just go out subordinate signals such as board district at PCB.

When the second PCB (14) reaches the PCB working area, the working state of the first PCB (14) is repeated.

At the moment, a waiting photoelectric sensor (16) in a PCB waiting area is switched from a high level to a low level, an upper computer judges that the PCB waiting area has no PCB (14), a chip mounter sends a signal of the PCB, a third PCB (14) flows into a working area of the chip mounter, a feeding motor (8) drives a feeding belt component (7) to flow and brings the third PCB (14) to the PCB waiting area, in the process, a working photoelectric sensor (17) in the PCB working area is at the high level, upper computer software judges that the PCB working area has the second PCB (14), the chip mounter works, the feeding belt component (7) brings the third PCB (14) to the PCB waiting area, the waiting photoelectric sensor (16) in the PCB waiting area is switched from the low level to the high level, the feeding motor (8) stops rotating, and therefore the feeding belt component (7) stops flowing. The third PCB board (14) waits for the second PCB (14) to complete in the waiting area.

At this time, the assembly line has three boards, a first PCB (14) in the PCB out-board area, a second PCB (14) in the PCB working area, and a third PCB (14) in the PCB waiting area.

This is the three-stage working mode of PCB pipeline.

A production line is composed of two production line seats (12), the assembly mode of each production line seat (12) is the same, and only one production line seat (12) and related parts thereof are shown in figures 4-9.
