In one embodiment, referring to fig. 14 to 18, the inclined slide 320, the substrate separating mechanism 330 and the substrate pushing mechanism 340 are all mounted on the middle mold plate 130, and the vibrating plate 310 and the middle mold plate 130 are all fixedly mounted on the frame 101.

The working principle of the substrate conveying device is as follows: firstly, the substrates are automatically arranged and output by the vibrating disk 310, then the substrates are conveyed into the substrate separating mechanism 330 through the inclined slide 320, the substrates are queued and sequentially enter the horizontal guide chute 336 and the vertical separating chute 337, then the substrate separating telescopic driving mechanism 335 drives the separating push plate 334 to extend out, and a single substrate in the vertical separating chute 337 is horizontally moved to the position above the vertical guide sleeve 339, so that the substrate passes through the vertical guide sleeve 339 and then falls into the clamping groove 343 of the automatic clamping jaw 342; the automatic clamping jaw 342 extends the substrate pushing and stretching driving mechanism 341 after clamping the substrate, and pushes the substrate to the upper part of the mold cup 131, specifically to the lower core bar 111; after the upper core rod 111 supports against the substrate, the automatic clamping jaw 342 is loosened, the substrate pushes the telescopic driving mechanism 341 to contract, and the automatic clamping jaw 342 returns to the original position.

controlling the pressing device 100 to work, wherein the upper core rod 141 and the upper punch 142 are pressed downwards, the upper core rod 141 firstly props against the matrix, the compression spring 148 is compressed in the process that the upper punch 142 descends for a certain distance, the upper core rod 141 and the upper punch 142 continue descending, the matrix is pressed on the lower core rod 111 and continues descending, and meanwhile, the lower core rod 111, the upper core rod 141 and the upper punch 142 synchronously descend together to send the matrix into powder in the die cup 131; when the upper punch 142 starts to press the powder in the die cup 131, the lower punch 121 also starts to move upwards at the same speed as the upper punch 142, and the powder is pressed in two directions under the extrusion of the upper punch 142 and the lower punch 121; after the powder in the die cup 131 is pressed to a preset height, the upper punch 142, the lower punch 121 and the lower core rod 111 stop moving, and the pressure is maintained for a period of time, so that the pressed and formed powder is fully shaped; finally, the upper punch 142, the lower punch 121 and the lower core rod 111 move upwards to eject the pressed beads out of the die cup 131.

the base pushing telescopic driving mechanism 341 retracts, the third telescopic driving mechanism 143 slowly extends, the upper core rod 141 and the upper punch 142 slowly descend by a predetermined distance (e.g., 10 mm), until the compression spring 148 is compressed to the bottom, the upper core rod 141 and the lower core rod 111 push the base without clearance, when the pressure of the pressure sensor 113 on the lower core rod 111 obviously rises (e.g., 50 kg), the first telescopic driving mechanism 112 slowly retracts, the upper punch 142 and the upper core rod 141 synchronously descend by a predetermined distance (e.g., 12 mm), the second telescopic driving mechanism 122 rapidly extends, the lower punch 121 rapidly rises by a predetermined distance (e.g., 30 mm) and then slowly rises by a predetermined distance (e.g., 5 mm), and meanwhile, the upper punch 142 also slowly descends by a predetermined distance (e.g., 7 mm), and bidirectional pressing is completed.

S8, pressure maintaining:

after the upper punch 142 and the lower punch 121 are pressed in place, the preset time is kept, and the specific time is determined according to the actual pressing effect.

S9, bead unwinding:

the third telescopic driving mechanism 143 retracts rapidly, and the upper punch 142 and the upper core rod 141 are raised by a predetermined distance (e.g., 90 mm) and retract to the initial position; simultaneously, the lower punch 121 and the lower core rod 111 are raised at a medium speed by a predetermined distance (e.g., 20 mm) to a zero position to eject the pressed beads out of the die cup 131.

S10, resetting the lower punch 121:

the first telescopic driving mechanism 112 is rapidly withdrawn and the lower punch 111 is rapidly lowered by a predetermined distance (e.g., 55 mm) to return to the initial position.

S11, start the next cycle:

the next cycle was carried out in the same manner as in S1 to S10, and the previous pressed beads were pushed out while feeding the powder.
