[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] like Figure 1 As shown, an automatic punching platform includes a conveyor frame 2. The conveyor frame 2 is a main structure and is firmly installed in the working area. Its length and width are designed according to the size of the plate to be punched to ensure that the plate can be smoothly transported. 30 transmission rollers 3 for conveying the plate to be punched are installed on the conveyor frame 2. The left and right edges of the upper surface of the conveyor frame 2 are respectively fixed with a stopper 1. The design of the stopper 1 needs to take into account the width and shape of the plate to ensure that the plate can maintain a straight line motion during the conveying process to prevent deviation; a sliding platform 6 is provided on one side of the conveyor frame 2. 6 is installed with a sliding seat 7, and a stepping motor 8 is fixedly installed on the sliding seat 7. A drill bit 9 for drilling holes in the plate to be punched is fixedly installed on the output end of the stepping motor 8; a suspension beam 4 is fixedly installed on the other side of the conveying frame 2, and the upper end of the suspension beam 4 extends to the top of the conveying frame 2 and is fixedly installed with a clamping cylinder 5 for clamping the plate to be punched. The clamping cylinder 5 is installed on the suspension beam 4 through a fixing device, and a clamping claw or other clamping mechanism is installed at the end of its piston rod. The clamping cylinder 5 is used to firmly clamp the plate on the conveying frame 2 before punching to prevent the plate from moving during the punching process.

[0021] The transmission roller 3 is driven by an external motor through a transmission device such as a chain or a belt to provide power to move the plate forward. The external motor is installed in an appropriate position and is connected to the transmission roller 3 through a coupling, a reducer and other devices.

[0022] The sliding seat 7 includes a pushing mechanism, a translation mechanism and a lifting mechanism. The pushing mechanism and the translation mechanism both realize the horizontal movement of the sliding seat 7 on the sliding platform 6 through motors, screws, guide rails and other devices. The pushing mechanism drives the stepping motor 8 to drill holes, and the translation mechanism drives the adjustment of the drilling position; the lifting mechanism realizes the up and down lifting of the sliding seat 7 and the components thereon through cylinders, screws, springs and other devices.

[0023] A first infrared distance sensor 10 for detecting the position and length of the plate to be punched and a second infrared distance sensor 11 for detecting the thickness of the plate to be punched are also fixedly mounted on the conveyor frame 2 .

[0024] It also includes a controller with a PLC. The first infrared distance sensor 10, the second infrared distance sensor 11, the clamping cylinder 5 and the stepping motor 8 are all electrically connected to the controller. The PLC controller, as the core of the entire system, is installed in a position that is convenient for operation and maintenance. The first infrared distance sensor 10, the second infrared distance sensor 11, the clamping cylinder 5, the stepping motor 8 and the subsequently added compressed air gun and other components are electrically connected to the PLC controller through cables or wirelessly to ensure that the PLC can receive signals from each component and issue control instructions according to preset programs.

[0025] An installation position for a compressed air gun is set on the conveyor rack 2. The compressed air gun is connected to an external air source through an air pipe and is started after the punching is completed to blow away dust and debris on the plate. The control switch of the compressed air gun is connected to the PLC controller, and the PLC issues a start command based on the punching completion signal.

[0026] Working principle: When in use, place the plate to be punched on the conveyor rack 2, and start the external motor to drive the transmission roller 3 to rotate, so that the plate is conveyed forward. When the first infrared distance sensor 10 detects the position and length of the plate, the PLC sends a signal to control the clamping cylinder 5 to clamp and fix the plate. At the same time, the second infrared distance sensor 11 detects the thickness of the plate and transmits the data to the PLC. The PLC adjusts the position of the stepper motor 8 and the lifting height of the sliding seat 7 according to the thickness of the plate. The PLC sends an instruction to start the stepper motor 8 to drive the drill bit 9 to rotate the pushing mechanism to advance the stepper motor 8 to perform the punching operation. After the punching is completed, the stepper motor 8 reverses to pull out the drill bit 9. At the same time, the clamping cylinder 5 releases the plate, and the compressed air gun starts to blow away the dust and debris on the plate. The transmission roller 3 continues to rotate to transport the punched plate to the next process or collection area.

[0027] The conveying frame 2, the driving roller 3, the clamping cylinder 5, the sliding seat 7, the stepping motor 8, the drill bit 9, the first infrared distance sensor 10, the second infrared distance sensor 11, the controller with PLC, and the compressed air gun are all universal standard parts or components known to those skilled in the art. Their structures and principles can be known to those skilled in the art through technical manuals or through conventional experimental methods, so they will not be described in detail here.

[0028] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited to the above embodiments. The above embodiments and descriptions only illustrate the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model will also have various changes and improvements, and these changes and improvements will fall within the scope of the utility model to be protected.
