DETAILED DESCRIPTION

[0024] See also Figures 1-4 , the embodiments of the utility model are further described;

[0025] like Figures 1-2 As shown, a punching device for aluminum plate processing comprises: a support base 1, a workbench 2, a hole detection component 6 and a PLC controller 5. The workbench 2 is fixed on the support base 1 and is used for aluminum plate punching operations. An inner groove 21 is opened inside the workbench 2. The upper end and one side end of the inner groove 21 penetrate the surface of the workbench 2, and the inner bottom of the inner groove 21 is an inclined surface. The height of the inner bottom of the inner groove 21 decreases from the inside to the outside, so as to facilitate the discharge of the debris generated by the punching from the inner groove 21. An elastic support member for supporting the hole position of the aluminum plate is installed in the inner groove 21, which can effectively prevent the hole position of the aluminum plate from being damaged due to the absence of elastic support members. The support causes the aluminum plate to deform during the punching process; the hole detection component 6 is installed on the support base 1 and is located obliquely above the workbench 2; the PLC controller 5 is installed on the support base 1, and the PLC controller 5 is electrically connected to the hole detection component 6. After the holes in the aluminum plate are punched, the hole detection component 6 will move to the top of the hole position of the aluminum plate under the control of the PLC controller 5 to detect the holes on the aluminum plate. The detection results will be fed back to the PLC controller 5. The workers can know whether the aluminum plate after punching meets the standards through the PLC controller 5, and can promptly discover whether the processed aluminum plate is defective.

[0026] like Figure 1 As shown in or 2, a pair of clamps 25 are installed on the workbench 2, and the inner groove 21 is located between the pair of clamps 25. The clamps 25 are used to clamp the aluminum plate to be punched. A hydraulic cylinder 3 is fixed on the top of the support seat 1, and a punch 4 is fixed on the output end of the hydraulic cylinder 3. The punch 4 is located above the inner groove 21, and a solenoid valve is installed at the oil inlet end of the hydraulic cylinder 3, and the solenoid valve is electrically connected to the PLC controller 5. An oil tank filled with hydraulic oil is provided outside the device, and a liquid pump is installed in the oil tank. The liquid pump is connected to the oil inlet end of the hydraulic cylinder 3, and the liquid pump is electrically connected to the PLC controller 5; when punching, the PLC controller 5 starts the liquid pump and the solenoid valve to drive the output end of the hydraulic cylinder 3 to move downward, thereby driving the punch 4 to punch the aluminum plate. This technology is based on the existing hydraulic system.

[0027] Specifically, Figure 3 As shown, the elastic support member includes a support block 22 and a plurality of spring shafts 23. The support block 22 is located above the inner groove 21 and is used to support the hole position of the aluminum plate. A slag discharge hole 24 is passed through the center of the surface of the support block 22. The slag discharge hole 24 matches the punch 4. The debris generated by punching will fall into the inner groove 21 through the slag discharge hole 24. One end of the plurality of spring shafts 23 is fixed to the bottom of the inner groove 21, and the other end is fixed to the bottom of the support block 22. The setting of the spring shaft 23 is conducive to the support block 22 to resist the hole position of the aluminum plate, which effectively solves the current problem of large deformation of the aluminum plate after punching due to the large area without support near the hole position of the aluminum plate. When punching and the support block 22 is subjected to impact force, the spring shaft 23 will undergo slight elastic deformation to buffer the impact force, thereby extending the service life of the elastic support member.

[0028] As Figure 1 , 2 and as shown in Figure 4, the hole detection component 6 includes an electric push rod 61, a mounting plate 62 and a pinhole camera 63. The electric push rod 61 is horizontally fixed on the support base 1 and is located obliquely above the workbench 2. The mounting plate 62 is fixed to the output end of the electric push rod 61. The electric push rod 61 is used to drive the mounting plate 62 to change the position of the mounting plate 62. The pinhole camera 63 is installed at the bottom of the mounting plate 62, and the pinhole camera 63 is electrically connected to the PLC controller 5. The pinhole camera 63 is used to photograph the aluminum plate after punching. The hole detection component 6 further includes an annular lamp 64. The annular lamp 64 is installed at the bottom of the mounting plate 62 and surrounds the pinhole camera 63. After the annular lamp 64 is turned on, it will illuminate the aluminum plate, which is beneficial for the pinhole camera 63 to clearly photograph the hole position of the aluminum plate.

[0029] The working principle of this device is as follows:

[0030] Before punching, first use the pinhole camera 63 in the hole detection component 6 to photograph the image of the aluminum plate standard part after punching. This image will be transmitted to the PLC controller 5 as the standard for qualified punching. Then, use the fixture 25 to clamp and fix the aluminum plate to be punched on the workbench 2, and align the hole position of the aluminum plate with the inner groove 21. At this time, under the elastic force of the spring shaft 23 of the elastic support member, the support block 22 of the elastic support member abuts against the punching position of the aluminum plate to support the punching position of the aluminum plate, effectively solving the problem that the aluminum plate undergoes large deformation after punching due to the lack of support in a large area near the hole position of the aluminum plate; it should be noted that the number of the inner grooves 21 provided and the distance between the inner grooves 21 can be set according to actual needs;

[0031] During punching, the hydraulic system is started through the PLC controller 5, so that the hydraulic cylinder 3 drives the punch 4 to punch down on the aluminum plate. The debris generated by punching will pass through the slag discharge hole 24 and fall to the bottom of the inner groove 21. Since the bottom of the inner groove 21 is an inclined surface, the debris in the inner groove 21 can be diverted outside the workbench 2, and there is no need for workers to manually clean the debris in the inner groove 21;

[0032] After punching, the PLC controller 5 controls the hydraulic system to drive the punch 4 to move upward through the hydraulic cylinder 3. When the punch 4 is far away from the aluminum plate, the PLC controller 5 will start the electric push rod 61 in the hole detection component 6 to drive the mounting plate 62 to move above the punching position of the aluminum plate. At this time, the PLC controller 5 will first start the annular lamp 64 to illuminate the aluminum plate after punching, then start the pinhole camera 63 to photograph the image of the aluminum plate, and then this image will be transmitted to the PLC controller 5. Workers can compare this image with the standard image to judge whether the aluminum plate after punching is qualified, or an image processing software can be installed in the PLC controller 5, and the PLC controller 5 automatically judges whether the aluminum plate after punching is qualified. This image processing technology is based on the existing image processing technology;

[0033] After the image is captured, the PLC controller 5 will control the electric push rod 61 to restore the mounting plate 62 to its original position, and then the electric push rod 61, the pinhole camera 63 and the ring light 64 will be turned off to continue the next round of aluminum plate punching.
