As shown in FIG. 1, a guide rod 27 is disposed on the inner side wall 14 of the paste applying apparatus, and a first sensor 28 and a second sensor 29 which can move along the guide rod are disposed on the guide rod 27. The first sensor 28 and the second sensor 29 face the front and rear side positions of the retainer 26, respectively. The second sensor 29 and the first sensor 28 are used for respectively detecting whether the PCB which is completely pasted leaves the area of the positioning supporting plate 22 or not and whether the PCB to be pasted completely reaches the designated position on the positioning supporting plate 22 or not, so that the automatic positioning, the automatic conveying and the automatic pasting of the PCB are realized.

As shown in fig. 3, a controller is connected to the first sensor 28 and the second sensor 19, and the controller controls the operation of the electric cylinder 251 and the conveyor belt 211. The first sensor 28 and the second sensor 29 are respectively a first photoelectric switch and a second photoelectric switch, and the emitting end 281 and the receiving end 282 of each of the first photoelectric switch and the second photoelectric switch are respectively arranged on two sides of the paste coating device parallel to the conveying belt 211.

Under the action of the first photoelectric switch, the second photoelectric switch and the controller, the conveyer belt 211 can be conveyed quickly, and the conveying and pasting operation can be realized at the maximum speed. As shown in fig. 6, the specific operations are:

after the gluing of the glued PCB 101 is completed, the gluing scraper resets, at this time, a signal is transmitted to the controller, and the upgrading mechanism 25 is controlled by the controller to drive the glued PCB 101 to descend onto the conveyer belt 211. At this time, the upgrading mechanism 25 is completely lowered, so that the positioning stoppers 26 on the positioning blade 22 are moved to a position lower than the conveying surface of the conveyor belt 211, so that the PCB 101 on which the glue is applied is not stopped in the forward conveyance.

Then, the lifting mechanism 211 stops descending, and transmits a signal to the controller, the conveyor belt 211 is controlled by the controller to convey forward, the glued PCB 101 is conveyed forward to the 102 position, which is called as an output PCB, the tail end of the output PCB just passes through a second photoelectric switch, and the second photoelectric switch senses that the output PCB is completely separated from the positioning support plate 22, and transmits the signal to the controller. The controller synchronously controls the lifting mechanism 25 to drive the positioning support plate 22 to move upwards, so that the positioning baffle 26 moves to a position higher than the conveying surface of the conveying belt 211, the upper surface of the positioning support plate 22 is still lower than the conveying surface of the conveying belt 211, and at this time, the upgrading mechanism 25 stops lifting. Meanwhile, the conveyer belt 211 is continuously conveyed forwards, the PCB100 to be glued is conveyed to the positioning supporting plate 22, the front end of the PCB100 to be glued and the rear side door base of the positioning top plate 26 are arranged, the first photoelectric switch senses a signal of the PCB100 to be glued and transmits the signal to the controller, and the conveyer belt 211 is controlled by the controller to stop conveying.

After the conveying belt 211 stops conveying, the lifting mechanism 25 moves upwards to drive the PCB board 100 to be glued to move upwards to the small surface of the paste coating screen 12, and then the lifting mechanism 25 stops working to perform the gluing operation. After the glue application is completed, the glued PCB board 101 is conveyed outward according to the above steps, and the PCB board 100 to be glued is conveyed onto the positioning pallet 22.

As can be seen from the above, when the PCB 101 subjected to the glue coating is conveyed outwards, the PCB is not required to be completely conveyed out of the glue coating apparatus, and only the PCB is required to be conveyed out of the positioning support plate 22, so that the conveying time of the PCB 101 subjected to the glue coating is shortened. Meanwhile, the PCB100 to be glued does not need to enter the positioning support plate 22 after the glued PCB 101 is completely conveyed out of the gluing device, and only needs to keep a certain distance between the PCB100 to be glued and the glued PCB 101, so that the positioning support plate 22 can be lifted when the glued PCB 101 is conveyed out of the positioning support plate 22, and at this time, the PCB100 to be glued does not reach the position of the positioning baffle 26 on the positioning support plate 22. The distance between two adjacent PCB boards on the conveyer belt 211 has been reduced to the setting of first photoelectric switch and second photoelectric switch, has improved rubber coated efficiency.
