[0025] The specific implementation is as follows: Step 1: Pick up chip 825: Figure 1 , Figure 3 and Figure 4 As shown, the first electric telescopic rod 3 is started, and the extended end of the first electric telescopic rod 3 drives the sleeve 4 and the handle pad 5 to descend, and the handle pad 5 drives the two picking air pipes 7 to descend, and the picking air pipe 7 descends and drives the pressure rod 813 to descend, prompting the pressure rod 813 to press the L-shaped force rod 812 in advance, and the L-shaped force rod 812 is forced to drive the slide plate 809 and the seesaw 811 to descend, and the seesaw 811 is blocked by the top block 826 when it descends and then flips, until the seesaw 811 and the top block 826 are staggered and are at the bottom of the uppermost top block 826, when the pressure rod 813 is lowered into place, the corresponding left picking air pipe 7 is at the top of the top support plate 805, and then the vacuum pump 6 is started to prompt the left picking air pipe 7 to adsorb the chip 825; Step 2: Workstation replacement: Figure 1 , Figure 8 , Fig. 9 , Fig.10As shown, the first electric telescopic rod 3 is started, causing the extended end of the first electric telescopic rod 3 to retract, and the retraction of the first electric telescopic rod 3 drives the sleeve 4, the storage sleeve 901 and the toothed plate 903 to rise. The toothed plate 903 will be blocked by the blocking plate 909 after rising for a certain distance, and then the toothed plate 903 is squeezed, and the toothed plate 903 is gradually retracted to the inside of the storage sleeve 901 due to the meshing of the toothed plate 903 with the gear 906, the gear 906 will drive the rotating shaft 905 to rotate, and the rotating shaft 905 rotates through the fit of the plane side of the short bevel block 9111 and the long bevel block 9113, so as to cause the first bevel gear 907 to rotate synchronously, and the rotation of the first bevel gear 907 will mesh with the second bevel gear 908. After the toothed plate 903 retracts to the limit, the second bevel gear 908 drives the sleeve 4, the handle pad 5 and the picking air pipe 7 to rotate 180 degrees to complete the position conversion; After the positions of the corresponding two picking air pipes 7 are changed through the upward and retracting linkage of the extended end of the first electric telescopic rod 3, since the L-shaped force-bearing rod 812 loses the downward pressure of the pressure rod 813, the L-shaped force-bearing rod 812 is pulled up and reset through the elastic cooperation of the first limiting sleeve 806, the first limiting rod 807 and the first reset spring 808, and the sliding plate 809 rises and resets to drive the seesaw 811 to lift the bottom of the top top block 826, and the top block 826 drives the placement frame 804 to rise, so that the second-layer pallet 805 synchronously carries the chip 825 to replace the position of the chip 825 on the first-layer pallet 805; Figure 7 As shown, the pallet 805 is automatically unfolded: when the second-layer pallet 805 replaces the first-layer pallet 805 loading position, the first-layer pallet 805 will be out of the interception limit range of the two bending limit plates 820, so during the rise of the first-layer pallet 805, it will be pushed out by the elasticity of the reset rod 818 and the fourth reset spring 819, and move to the outside of the placement frame 804, thereby automatically unblocking the subsequent adsorption loading surface of the chip 825; Step 3: Adsorption of chip 825 and docking of chip 825 with the PCB mainboard installation position: Before installing the right chip 825, place the PCB mainboard into the mainboard mold frame 11 in advance, and align the chip installation position on the top of the PCB mainboard with the bottom of the right pickup air pipe 7; After the workstation is switched, the bottom end of the picking air tube 7 on the left side does not have the chip 825 adsorbed thereon, while the bottom end of the picking air tube 7 on the right side adsorbs and carries the chip 825, and then the first electric telescopic rod 3 is started, and the extended end of the first electric telescopic rod 3 drives the sleeve 4 and the handle pad 5 to descend, and the handle pad 5 drives the two picking air tubes 7 to descend, and the picking air tube 7 descends and drives the pressure rod 813 to descend at the same time, prompting the pressure rod 813 to press the L-shaped force rod 812 in advance, and the L-shaped force rod 812 is forced to drive the slide plate 809 and the rocker 811 to descend, and the rocker 811 descends and is blocked by the top block 826 and then flips over at an angle until the rocker 81 1 is staggered with the top block 826 and is at the bottom of the second-layer top block 826, preparing for the loading of the chip 825 on the third-layer support plate 805. When the pressure rod 813 drops to the limit position, the corresponding left-side picking air pipe 7 contacts the chip 825 on the top of the second-layer support plate 805, and then the vacuum pump 6 is started to cause the unloaded left-side picking air pipe 7 to adsorb it. At this moment, the right-side picking air pipe 7 adsorbs the chip 825, and the chip 825 is located on the mounting surface at the top of the PCB mainboard. Then the right-side vacuum pump 6 is turned off to cause the right-side picking air pipe 7 to release the chip 825. Subsequently, it is only necessary to perform upper and lower limit travel operation on the extension end of the first electric telescopic rod 3 to continuously and synchronously realize the chip 825 picking, automatic station conversion and chip 825 release and installation; It should be noted that when the extension end of the first electric telescopic rod 3 extends downward from the limit height, the toothed plate 903 in the corresponding retracted state will gradually extend from the inside of the storage sleeve 901 due to the loss of the passive pressure of the blocking plate 909, and the toothed plate 903 extends out and meshes with the gear 906, prompting the gear 906 to drive the rotating shaft 905 to reverse, and the rotating shaft 905 reverses to drive the inclined surface of the short bevel block 9111 to squeeze the inclined surface of the long bevel block 9113. Since the first bevel gear 907 is in meshing state with the second bevel gear 908, and the second bevel gear 908 is in meshing state, There is a non-return cooperation between the connected sleeve 4 and the first electric telescopic rod 3, namely, a non-return bevel block 9102 and a non-return groove 9104, so the first bevel gear 907 is in a limited non-return state at this moment. Therefore, the bevel of the short bevel block 9111 squeezes the bevel of the long bevel block 9113, and the long bevel block 9113 retracts into the movable slide groove 9112, so that the rotating shaft 905 carries the short bevel block 9111 to perform its own reverse idling, so that it will not rotate during the process of picking up the air pipe 7 and descending, thereby ensuring the stability of the adsorption chip 825 and the stability of the installation chip 825.
