When the taping mechanism 200 is used for taping a PCB to be bordured, firstly, the adhesive tape wraps the corner of the PCB to be bordured manually, then under the driving action of the driving mechanism 100, the PCB to be bordured moves to drive the adhesive tape to rotate around the first positioning column 221 through the adhesive tape, and the adhesive tape sleeved on the first positioning column 221 rotates under the pulling action of the adhesive tape to enable the adhesive tape wound on the adhesive tape to be torn off from the adhesive tape for taping. In this embodiment, the user puts the taping tape over the first rolling bearing 223. In the process of the edge covering mechanism 200 for edge covering the PCB to be edge-covered, on one hand, the tape for edge covering, which is sleeved on the first rolling bearing 223, can rotate around the first rolling bearing 223, and on the other hand, the tape for edge covering, which is sleeved on the first rolling bearing 223, can rotate along with the rotation of the first rolling bearing 223. Thus, the first rolling bearing 223 ensures that the taping for edge covering can smoothly rotate under the tearing action of the adhesive tape, reduces the influence on the rotation of the taping for edge covering caused by overlarge friction force between the taping for edge covering and the first positioning column 221, stably provides the adhesive tape for the PCB edge covering device, and improves the working stability of the adhesive tape fixing component 220.

In the process of tearing the adhesive tape, the tearing direction of the adhesive tape is changed by the adhesive tape receiving assembly 230 so as to facilitate edge covering of the PCB to be edge-covered. Specifically, the smooth surface of the adhesive tape is in sliding contact with the second positioning column 221. During the hemming process, on the one hand, the gummed paper can slide along the second rolling bearing 233. On the other hand, when the friction between the adhesive tape and the second rolling bearing 233 is too large, the second rolling bearing 233 is forced to rotate to drive the adhesive tape to move. Thus, the second rolling bearing 233 ensures that the adhesive tape can smoothly slide to be continuously torn off from the adhesive tape when passing through the adhesive tape receiving assembly 230, reduces the influence on the rotation of the adhesive tape for edge covering caused by the excessive friction force between the adhesive tape and the second positioning post 221, stably provides the adhesive tape for the PCB edge covering device, and improves the working stability of the adhesive tape receiving assembly 230.

In another embodiment, the control mechanism includes an upper computer and a lower computer, the upper computer being electrically connected to the lower computer. In the working process of the PCB edge covering device, the control mechanism controls the transmission motor 410 in the transmission mechanism 400 to rotate so as to drive the transmission belt 420 to move, and the containing groove 401 formed in the transmission belt 420 is used for containing a PCB to be covered. After the control mechanism controls the conveying motor 410 to rotate for a first preset time, a PCB to be edged is pushed to the driving shafts 120 in the driving mechanism 100 under the pushing action of the conveying belt 420. The control mechanism controls the driving motor 110 to rotate to drive the plurality of driving shafts 120 to rotate, so as to drive the plurality of driving wheels 121 to rotate. A number of drive wheels 121 rotate to drive the PCB to be edged towards the working space 201. The control mechanism controls each pushing member 250 to push a carrying plate 210 to move so as to regulate and control the distance between the two binding mechanisms 200, namely the width of the working space 201. The width of the working space 201 is made to be matched with the width of the PCB to be covered, and the application range of the PCB covering device is widened. Further, when the driving mechanism 100 drives the PCB to be wrapped to the working space 201, the control mechanism controls the auxiliary motor 510 to rotate to drive the auxiliary rotating shaft 520 to rotate so as to further receive and drive the PCB to be wrapped. In order to correct the position of the PCB to be wrapped, when the PCB to be wrapped is pushed onto the plurality of driving shafts 120, the control mechanism controls the transverse air cylinders 311 arranged on both sides of the plurality of driving shafts 120 to push the transverse pushing frame 312 to correct the position of the PCB in the transverse direction. It should be noted that, when the lateral correcting component 310 corrects the position of the PCB to be wrapped, the control mechanism controls the driving mechanism 100 to stop working, and after the correction is completed, the control mechanism controls the driving mechanism 100 to continue working. When the PCB to be edged is pushed to the working space 201, the longitudinal roller 321 provided between the edging mechanism 200 and the driving shaft 120 performs a limiting process in the vertical direction on the PCB to be edged. So that the position of the PCB to be wrapped by the correction mechanism 300 is corrected. The control mechanism coordinates the driving motor 110, the transmission motor 410, the pushing piece 250, the auxiliary motor 510 and the two transverse cylinders 311, and improves the working stability of the PCB edge covering device.
