[0103] Reference Figures 1 to 11 The technical solution of the present invention relates to a PCB production line, comprising: a loading station 200, which is arranged adjacent to each other in sequence, for uploading workpieces into a tray; a glue dispensing station 300, which is used to dispense glue and perform optical inspection on the workpiece; a safety test station 400, which is used to perform safety testing on the workpiece; a laser marking station 500, which is used to mark the workpiece corresponding to the processing; a downline station 600, which is used to separate the finished workpieces and the NG workpieces, and to pack the finished workpieces for downline; a rotary line assembly 100, which comprises a first elevator 110, a second elevator 120, and an upper transmission line 130 and a lower transmission line 140 arranged between the first elevator 110 and the second elevator 120, wherein the first elevator 110 is arranged on one side of the loading station 200, and the second elevator 120 is arranged between the downline station 600 and the laser marking station 500, and the upper transmission line 130 and the lower transmission line 140 are respectively used to transport the tray loaded with workpieces and the empty tray.

[0104] During the production process, the upper transmission line 130 transmits the empty tray to the loading station 200, the workpiece is placed in the tray at the loading station 200 by manual feeding, and the tray loaded with the workpiece is transmitted to the dispensing station 300 by the upper transmission line 130. A lifting mechanism 390 is provided at the junction of the upper transmission line 130 and the dispensing station 300, as well as at the junction of the upper transmission line 130 and the safety testing station 400 and the laser marking station 500. The tray transmitted to the corresponding station is lifted up and separated from the upper transmission line 130 by the lifting mechanism 390, and is transmitted to the corresponding station by the belt to carry out the corresponding process. After the tray enters the dispensing station 300, it is lifted by the dispensing worker. The dispensing head 330 in the position 300 dispenses glue to the workpiece, and the detection component 360 detects the dispensing condition of the workpiece and the overall appearance of the workpiece. Then the tray returns to the upper transmission line 130, and is further transported by the upper transmission line 130 to the safety testing station 400 for a withstand voltage test, and is transported to the laser marking station 500 for processing the corresponding logo, and is finally transported to the second elevator 120. After the workpiece on the tray is obtained by the offline station 600, the second elevator 120 lowers the empty tray to the lower transmission line 140, and is transported back to the first elevator 110 by the lower transmission line 140. The first elevator 110 raises the empty tray to the upper transmission line 130 to continue the above process.

[0105] Through the upper transmission line 130 and the lower transmission line 140 in the rotary line assembly 100, the trays loaded with workpieces and the empty trays are transferred between the loading station 200, the dispensing station 300, the safety testing station 400, the laser marking station 500 and the offline station 600 respectively. The first elevator 110 and the second elevator 120 are used to lift and transfer the trays between the upper transmission line 130 and the lower transmission line 140. The whole process does not require manual transfer of workpieces and trays. Manual loading of workpieces into the trays is only required at the loading station 200, thereby improving the production efficiency of the entire production line.

[0106] According to some embodiments of the present invention, the glue dispensing station 300 includes: a first machine 310, on which a first conveyor belt 315 is provided along the X-axis direction, the first conveyor belt 315 is arranged perpendicular to the upper transmission line 130, and a lifting mechanism 390 is arranged at the intersection of the first conveyor belt 315 and the upper transmission line 130; a displacement module 320, which is arranged on the first machine 310 and located above the first conveyor belt; a glue dispensing head 330, which is arranged on the displacement module 320, and the displacement module 320 is used to drive the glue dispensing head 330 to approach the workpiece on the tray for glue dispensing; a verification component 340, which is arranged on the first machine 310, and the verification component 340 is used to position the glue dispensing head 330; a scraping component 350, which is arranged on the first machine 310, and the scraping component 350 is used to scrape off the residual glue on the glue dispensing head 330; a detection component 360, which is arranged on the first machine 310 and located above the first conveyor belt, and the detection component 360 is used to detect the integrity and glue dispensing condition of the product.

[0107] The displacement module 320 drives the dispensing head 330 to approach the material tray and dispense glue to the workpiece on the material tray. During the process, the dispensing head 330 is positioned and glued by the verification component 340 and the scraping component 350 respectively. Finally, the integrity and dispensing of the workpiece are optically inspected by the detection component 360. The whole process is automated without manual intervention, which improves the position accuracy of dispensing and the precise control of the dispensing amount, thereby improving the yield rate of the workpiece.
