[0071] Furthermore, a second aspect of this embodiment provides a trimming method for an automatic trimming device, comprising the following steps:

[0072] S1. The board material to be trimmed enters the first mounting frame 110 via the first conveyor belt 120;

[0073] S2. When the first positioning photoelectric sensor 140 detects that the plate has reached the front end of the first mounting beam 111, the first conveyor belt 120 stops moving.

[0074] S3. The first lifting unit lifts the plate on the first conveyor belt 120 to a specified height; then, two first positioning electric cylinders 220 simultaneously push one side of the plate to a specified position for centering, and two second pushing cylinders 230 extend to assist in straightening the other side of the plate. After centering, the first pushing cylinder 230 returns to its original position first, and the first positioning electric cylinder 220 returns to its original position later to prevent deviation. After centering, the first positioning electric cylinder 220 and the first pushing cylinder 230 retract, the first lifting unit descends, and the plate is placed back on the first conveyor belt 120.

[0075] S4. The first conveyor belt 120 continues to move. When the plate after centering passes the first mounting beam, the first cutting unit 330 cuts the two longitudinal sides of the plate. At this time, the collecting cylinder 132 lifts the collecting plate 131, and the cut edge material falls onto the collecting plate 131. After the cutting is completed, the collecting cylinder 132 retracts, and the collecting plate 131 tilts downward so that the edge material falls into the first collecting frame 133. After the cutting is completed, the plate is transported to the conveyor table 400 by the first conveyor belt 120.

[0076] S5. The conveyor table 400 conveys the sheet material to the second conveyor belt 520. The sheet material is conveyed on the second conveyor belt 520 until it abuts against the stop unit 530, and the second conveyor belt 520 stops moving.

[0077] S6, the lifting frame 620 lifts the plate to the specified height; then the two second positioning electric cylinders 710 simultaneously push the plate to center it, and the two second pushing air cylinders 720 extend to assist in straightening the plate. After centering is completed, the second positioning electric cylinder 710 and the second pushing air cylinder 720 clamp the plate.

[0078] S7. The transverse drive unit 820 drives the crossbeam to slide along the second direction on the second slide rail 514, and the two second cutting units 840 cut the two sides of the plate in the transverse direction; the cut edge material falls into the lifting frame 620.

[0079] S8. The second positioning electric cylinder 710 retracts first, the second pushing air cylinder 720 retracts later, the lifting frame 620 descends, and the trimmed board and edge material are transported back to the second conveyor belt 520. The board is then transported out through the second conveyor belt 520 to complete the trimming. At the same time, the edge material is conveyed through the second conveyor belt and falls into the second collection frame 540.

[0080] As can be seen from the above, this utility model automatically adjusts the position of the board before trimming by setting the first adjustment component and the second adjustment component, thereby improving processing accuracy and realizing automatic trimming of the board; by setting a stop unit on the second transmission component, processing accuracy is improved; by setting a collection unit to support the edge strip during cutting to prevent corner and edge chipping, and by setting a second collection frame to collect the edge strip after cutting, the edge material is automatically recycled, reducing the labor intensity of technicians, improving the working environment of technicians, increasing work efficiency, and reducing the production cost of enterprises; at the same time, the positions of the first cutting unit and the second cutting unit in this application are adjustable, which can adapt to the processing of various specifications of boards; in this embodiment, the long side and the short side of the board are processed at two different workstations, which improves efficiency; when processing the same type of board, the first adjustment component, the second adjustment component, and the lifting of the cutting head do not need to be adjusted, which improves the convenience of processing.

[0081] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
