The combined four-axis manipulator 4 is provided with a combined fixture 9, and the combined fixture 9 comprises a fixture connecting seat 90, a circuit board lifting cylinder 91 arranged on both sides of the fixture connecting seat 90, a circuit board vacuum suction cup group 92 arranged on the circuit board lifting cylinder 91, a pressing base 93 arranged at the bottom of the fixture connecting seat 90, a pressing slide 96 lifted and lowered along the pressing base 93, a shield cover picking and placing cylinder 97 arranged on the pressing slide 96, and a shield cover vacuum suction cup group 92 arranged on the shield cover picking and placing cylinder 97. A suction nozzle 99 and an upper pressing seat 98 are arranged at the bottom of the pressing slide 96. The bottom of the pressing seat is provided with an upper pressing ridge 990 extending along the edge of the shielding cover. The upper pressing seat 98 is provided with a suction nozzle avoidance hole 991 for avoiding the vacuum suction cup of the shielding cover. A pressing elastic member 95 is connected between the pressing slide 96 and the pressing base 93. The pressing elastic member 95 applies a downward elastic force to the pressing slide 96; when the vacuum suction cup of the shielding cover is in the upper limit position, the bottom of the vacuum suction nozzle 99 of the shielding cover is higher than the upper pressing ridge 990, and when the vacuum suction cup of the shielding cover is in the lower limit position, the bottom of the vacuum suction nozzle 99 of the shielding cover is lower than the upper pressing ridge 990; the tray loading assembly 6 is used to provide loading and unloading of the tray, and the conveyor line 5 is used to convey circuit boards.

[0027] By combining the combined fixture 9 on the four-axis manipulator 4, the shielding cover can be automatically taken and placed and then pressed. The circuit board can be automatically loaded and unloaded through the conveyor line 5, and the whole process can be unmanned, which improves work efficiency and ensures the consistency of pressing. The combination of the shielding cover vacuum suction nozzle 99 and the upper pressing seat 98 facilitates the reduction of the structural volume. The pressing elastic part 95 prevents the pressing failure caused by the large impact force during pressing.
