Referring to fig. 7 and fig. 8, this paragraph details a specific flow of the conveying apparatus 100 for conveying the circuit board 4. Firstly, the processing unit 1 controls the rolling coating device 2 to pivot reversely, so that the circuit board 4 positioned between the coating wheels 21 is pressed by the coating wheels 21 to roll upwards, and the two surfaces 41 of the circuit board 4 are simultaneously adhered with the ink in the rolling process. When the upper edge 42 of the circuit board 4 is rolled out of the coating wheel 21, the position of the circuit board 4 can be detected in real time by a sensor (not shown) electrically connected to the processing unit 1, and a signal is transmitted to the processing unit 1, the processing unit 1 controls the operation of the telescopic module 312 and the translation module 313 of the transmission unit 31, so that the chuck module 321 of the gripping device 3 aligns with the upper edge 42 of the circuit board 4 in the front-back direction D2 and the left-right direction D3, and the processing unit 1 can adjust the positions of the second sliding blocks 313b of the translation module 313 in the left-right direction D3 according to circuit boards 4 with different sizes, so that the chuck modules 321 respectively connected to the second sliding blocks 313b can be evenly clamped at the positions of the circuit board 4.
When the upper edge 42 of the circuit board 4 is rolled to be adjacent to the chuck module 321, the processing unit 1 controls the pressing member 321b of each chuck module 321 to move towards each other relative to the chuck body 321a, so that the pressing member 321b jointly clamps the circuit board 4. Then, the processing unit 1 controls the first slider 311c of the lifting module 311 to slide upward to drive the clamping unit 32 to move upward relative to the roll coating device 2 at the second speed. In this embodiment, the second speed is slightly greater than the first speed, so when the chuck module 321 clamps the circuit board 4 between the coating wheels 21 and is driven by the transmission unit 31 to pull up the circuit board 4, the rod 322d (see fig. 6) of the buffer module 322 is pulled down by the chuck module 321 due to the speed inconsistency between the clamping unit 32 and the roll coating device 2, and the gas in the cylinder body 322c (see fig. 6) of the buffer module 322 is compressed by the rod 322d to form a damping effect, so as to balance the first speed and the second speed, so that the circuit board 4 is not broken due to the different transmission speeds between the roll coating device 2 and the clamping unit 32, and a buffer force is accumulated during the balancing process.
When the gripping device 3 and the roll coating device 2 are continuously operated to clamp the coating wheel 21 on the lower edge 43 of the adjacent circuit board 4, the area of the coating wheel 21 contacting the surface 41 of the circuit board 4 decreases gradually, so that the friction force applied to the surface 41 decreases gradually until the buffer force in the buffer module 322 is greater than the friction force applied to the surface 41 by the coating wheel 21, and the gas in the cylinder body 322c pushes the connecting rod 322d to cause the clamping unit 32 to be instantly lifted upwards by the action of the connecting rod 322d, so that the circuit board 4 is instantly pulled out from between the coating wheels 21, and the ink is not accumulated on the lower edge 43 of the circuit board 4.
To sum up, the utility model discloses conveying equipment 100 is in through setting up a plurality of buffer module 322 transmission unit 31 with between the chuck module 321, make circuit board 4 can not cause the circuit board 4 fracture because the transmission rate of roll extrusion coating unit 2 and clamping unit 32 is different, and works as coating wheel 21 centre gripping is adjacent the lower edge 43 of circuit board 4, promptly coating wheel 21 centre gripping in the area of circuit board 4 reduces, the buffer capacity can be overcome coating wheel 21 is right the frictional force that circuit board 4 caused will circuit board 4 is followed take out in the twinkling of an eye between the coating wheel 21, makes printing ink can not accumulate in the lower edge 43 of circuit board 4, so can reach cost utility model's purpose really.
