[0031] In the embodiment of the present invention, the handle is U-shaped, and both ends thereof extend forward to pass through the transfer frame and are fixedly connected to the transfer frame, and the rear end of the handle extends obliquely backward and upward; the bottom of the stacking frame is supported by support legs 28.

[0032] In the embodiment of the present invention, a baffle 6 is provided on the left side of the lifting frame to prevent the artificial board from sliding out, so as to prevent the artificial board from falling under the continuous horizontal transportation of the roller conveying mechanism. The baffle is inclined upward from right to left.

[0033] In order to facilitate the adjustment of the distance between the baffle and the roller closest to the baffle, so that the middle part of the artificial board can be located directly above the rear belt conveyor mechanism, thereby facilitating the longitudinal transportation of the artificial board, a straight groove 61 is provided on the baffle, in which a positioning pin 62 is fixed, and a baffle cylinder 7 for pulling the baffle to slide along the inclined groove is provided on the lifting frame to adjust the distance between the baffle and the roller closest to the baffle; the upper end of the baffle cylinder is hingedly fixed on the lifting frame, and the output shaft of the baffle cylinder is hingedly fixed on the baffle; when the length of the artificial board increases or decreases, and the distance between the baffle and the roller closest to the baffle needs to be increased or decreased, the baffle is pulled by the baffle cylinder to slide along the inclined groove for adjustment.

[0034] There is a certain distance between the baffle and the roller closest to the baffle. A guide roller 8 for assisting in guiding the artificial board to move along the rear belt conveyor mechanism is arranged on the left side of the baffle. The guide roller is arranged vertically.

[0037] A pneumatic cylinder or hydraulic cylinder is arranged under the above-mentioned stepping lift table to drive the stepping lift table to move up and down. Since the suction cup mechanism can only move forward and backward, when the artificial board on the stepping lift table is sucked up by the suction cup mechanism and sent to the roller conveying mechanism, the pneumatic cylinder or hydraulic cylinder drives the stepping lift table to lift up, so that the stacked artificial board rises by the thickness of one artificial board, so as to facilitate the next suction of the suction cup mechanism; in addition, the suction cup mechanism can also be provided with a lifting mechanism to assist in sucking the artificial board.

7. The working method of the automatic drilling device for artificial panels is characterized by: The automatic drilling device for artificial boards as described in any one of claims 1 to 6 is used, and the following steps are followed: first, the pulley is pushed to the side position of the stacking rack, and the artificial boards stacked on the transfer rack can be pushed forward and pushed onto the stacking rack; then the pulley is continued to be moved to place the artificial boards on the adjacent stacking rack, and then the artificial boards on the stacking rack are pushed onto the stepping lifting platform to complete the preparation work; secondly, the stepping lifting platform lifts the stacked artificial boards to a height that the suction cup mechanism can absorb, the suction cup mechanism sucks up the left and right artificial boards and moves them from back to front, the lifting frame rises, the suction cup mechanism deflates and places the two artificial boards on the lifting frame, the lifting frame descends and resets, the rear belt conveyor mechanism is started, and the artificial boards on the left are conveyed along the length direction of the rear belt conveyor mechanism, at this time the lifting frame is slightly lifted again, so that the roller conveyor mechanism is higher than the rear belt conveyor mechanism to prevent interference, at this time the roller conveyor mechanism is started, and the one on the right The artificial board moves to the left side, and the lifting frame descends and resets. The artificial board is fully in contact with the rear belt conveyor mechanism and is also conveyed along the belt conveyor mechanism, and the cycle is repeated; finally, the artificial board is uniformly conveyed to the front belt conveyor mechanism by the rear belt conveyor mechanism. When it is conveyed to the bottom of the positioning cylinder, the front and rear belt conveyor mechanisms stop, and the piston rod of the positioning cylinder extends and presses down on the artificial board, and the artificial board is supported by the support frame; when conveying through the rear limit block, the artificial board will press down the rear limit block, and the spring will be compressed until the artificial board is conveyed to the bottom of the positioning cylinder, and the spring will be reset. At this time, the limit cylinder will be contracted and the front limit cylinder will be pushed out, so that the rear limit block is connected to the rear end of the artificial board and the front limit block is connected to the front end of the artificial board. After the limit is completed, the drill bit and the drilling cylinder can be started to drive the drill bit to move up to drill holes in the artificial board to complete the drilling work. After completion, the drilling cylinder, the limit cylinder and the front limit cylinder are reset, and the front and rear belt conveyors continue to convey, and the cycle is repeated.
