Further, the board feeding carrier 58 is arranged above the second fixing block 562, the board feeding carrier 58 is of a horizontal plate structure, a supporting column 580 extends from the lower side surface of the board feeding carrier 58, the supporting column 580 is fixedly arranged with the third base plate 53, and the horizontal surface of the board feeding carrier 58 is located below the lower pressing bracket 57 and forms a clamping space capable of clamping a PCB with the lower pressing bracket 57;

the front side surface of the board feeding carrier 58 is an inclined plane 581 structure, so that the PCB board can conveniently enter the clamping space between the pressing bracket 57 and the board feeding carrier 58, and the board feeding carrier 58 is recessed to form a fourth groove 582 corresponding to the cutting blade 568 and the movement space of the second pressing wheel 5601;

a photoelectric switch 5602 is arranged beside the driving cam 54, a photoelectric switch 5602 is arranged on one side of the board feeding carrier 58 corresponding to the fourth groove 582, and the photoelectric switch 5602 is used for detecting a corresponding action position to realize station detection of the telescopic rubberizing unit 56;

the control device is respectively connected to the first driving motor 21, the second driving motor 31, the third driving motor 51, the fourth driving motor 552, and the photoelectric switch 5602, and is used for controlling the cooperative operation of each station process.

In the above embodiments, the fixing and connecting manner of each component and each structure includes, but is not limited to, screwing, riveting, and the like, which are conventional in the art, and is not limited herein.

The working process is as follows: by applying the utility model, the PCB and the aluminum pad are fixedly placed on the processing substrate 4 in an overlapping manner, at the moment, the glue feeding unit 55 drives the adhesive tape to rotate, the adhesive tape surface is positioned at the front end opening position of the lower pressing bracket 57, the X-axis moving assembly 2 and the Y-axis moving assembly 3 drive the four adhesive tape sticking devices 5 to synchronously move to the side of the PCB, the side of the PCB enters the clamping space, the third driving motor 51 drives the driving cam 54 to move to push the telescopic adhesive tape sticking unit 56 to move, the lower pressing bracket 57 completes the lower pressing action, the adhesive tape is pressed to one side of the PCB, and the cutting blade 568 extends forwards to the adhesive tape to cut the adhesive tape;

drive cam 54 continues to promote flexible carrier 565 removes, first pinch roller 560, second pinch roller 5601 continue to remove towards the PCB board, and the sticky tape of the PCB board upper and lower downside that will overlap compresses tightly the laminating completely, accomplishes the automatic rubberizing action of PCB panel avris, removes subassembly 2, Y axle through the X axle and removes the drive of subassembly 3 rubberizing device 5 accomplishes the full-automatic rubberizing to PCB board four sides avris along the removal orbit of PCB board avris, and rubberizing parameter is accurate adjustable, and safe and reliable maintains the convenience, changes the tradition and removes artifical rubberizing mode, very is applicable to the working scene of PCB board, the full-automatic rubberizing in aluminium backing plate four sides.

For those skilled in the art, based on the teachings of the present invention, changes, modifications, substitutions and alterations to the embodiments will still fall within the scope of the invention.
