DETAILED DESCRIPTION OF THE EMBODIMENTS

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention;

[0035] Please refer to Figures 1-7, in the present invention: a pneumatic positioning type bending device, comprising a workbench 1, two conveyor belts 2 are installed on the top of the workbench 1, the left conveyor belt 2 is lower than the right conveyor belt 2, both the left and right sides of the workbench 1 are penetrated with a cylinder 1 3 fixedly connected thereto, opposite ends of the two cylinders 1 3 are fixedly connected with mounting blocks 4, opposite sides of the two mounting blocks 4 are rotatably connected with clamping plates 5, a motor 6 is installed inside the left mounting block 4, an output shaft of the motor 6 is fixedly connected with the left clamping plate 5, the top of the workbench 1 is fixedly connected with a box body 7, a dust cleaning mechanism 8 is arranged on the box body 7, a camera 9 is arranged above the left conveyor belt 2, the top of the camera 9 is installed on the workbench 1, a controller 10 and an image processing and analysis module 11 are installed on the front of the workbench 1, an output end of the camera 9 is in signal connection with the image processing and analysis module 11, an output end of the image processing and analysis module 11 is in signal connection with the controller 10, an electric push rod 12 fixedly connected thereto is penetrated through the top of the workbench 1, a telescopic end of the electric push rod 12 is fixedly connected with a pressing block 13, a groove 14 adapted to the pressing block 13 is formed in the top of the workbench 1, a positioning mechanism 15 is arranged on the workbench 1, and an input end of the electric push rod 12 is in signal connection with the controller 10; the positioning mechanism 15 includes a positioning plate 151, the bottom of the positioning plate 151 is fixedly connected with the workbench 1, a vertical plate 152 is fixedly connected to the top of the workbench 1, a cylinder 2 153 fixedly connected thereto is penetrated through the vertical plate 152, and a push plate 154 is fixedly connected to a telescopic end of the cylinder 2 153.

[0036] In the present invention, when the mylar sheet is bent, first place the mylar sheet on the top of the right conveyor belt 2, the conveyor belt 2 will move the mylar sheet closer to the two clamping plates 5. When the mylar sheet is located between the two clamping plates 5, simultaneously start the two cylinders 1 3, and the cylinders 1 3 will drive the two clamping plates 5 to approach the mylar sheet until the two clamping plates 5 are both in close contact with the mylar sheet, thereby realizing the preliminary positioning of the mylar sheet and clamping it.

[0037] After the mylar sheet is clamped, simultaneously start the two cylinders 1 3 to drive the two clamping plates 5 to move leftward. During the process, the mylar sheet will move to the bottom of the camera 9, and the camera 9 will collect the top image of the mylar sheet. Then the user starts the motor 6 to drive the clamping plate 5 to rotate 180 degrees, the mylar sheet will be turned over, and then start the camera 9 again to complete the collection of the reverse image of the mylar sheet.

[0038] After collecting the double-sided images of the mylar sheet, the image processing and analysis module 11 will analyze and process the images. When there are too many or too deep scratches and cracks on the surface of the mylar sheet, it is determined that the mylar sheet is a defective product. The defective product will break and deform during bending. If there are no cracks and scratches on the surface of the mylar sheet, or the scratches and cracks that appear are few and not deep, it is determined that the mylar sheet can be bent and processed without breaking and deforming.

[0039] When defective products appear, the two cylinders 3 are opened one after the other until the clamping plates 5 are reset. The opening of the two cylinders 3 one after the other will cause the two clamping plates 5 to lose their clamping on the mylar sheet, so the mylar sheet will fall onto the conveyor belt 2 on the left side. The conveyor belt 2 conveys the defective products to the rear of the workbench 1, completing the discharging of the defective products.

[0040] When the mylar sheet can be bent subsequently, after driving the mylar sheet above the groove 14, the cylinder two 153 is opened to drive the push plate 154 to move. The push plate 154 will push the mylar sheet towards the positioning plate 151, thereby achieving the effect of positioning the mylar sheet. Then, the electric push rod 12 is opened to drive the pressing block 13 to descend. The pressing block 13 will press the mylar sheet into the groove 14. The outer side of the mylar sheet will contact the inner wall of the groove 14 and the pressing block 13 respectively, thereby achieving the bending and forming of the mylar sheet and completing the bending effect of the mylar sheet.

[0041] After completing the bending of the mylar sheet, the bent mylar sheet is taken out from the groove 14, and the clamping plates 5 are reset, then the bending process can be carried out on the next mylar sheet.

[0042] Please refer to Figures 1-4 As shown in the figure, the dust cleaning mechanism 8 includes a blower 801. The blower 801 is installed on the top of the box body 7. Two air outlet pipes 802 are communicated with the bottom of the box body 7. The bottom ends of the two air outlet pipes 802 both penetrate through the workbench 1 and extend to both sides of the camera 9.

[0043] In the present invention, when the mylar sheet is flipped and the graphic is collected, the user can turn on the blower 801 to input air into the box body 7. The air will be sprayed from the air outlet pipes 802 onto the surface of the mylar sheet, thereby achieving the effect of cleaning the dust on the surface of the mylar sheet, effectively avoiding the situation that the dust on the surface of the mylar sheet affects the bending quality and effect.

[0044] Please refer to Figure 2 As shown in the figure, a filter plate 16 is inserted into the left side of the box body 7 and is slidably connected to it. The right side of the filter plate 16 is located inside the box body 7.

[0045] In the present invention, the setting of the filter plate 16 can filter the air sprayed onto the mylar sheet, avoiding the situation that the dust in the air contaminates the mylar sheet, thereby improving the dust cleaning effect on the mylar sheet.

[0046] Please refer to Figure 2 As shown in the figure, two electric heating rods 17 are installed on the left side of the box body 7. The heating ends of the two electric heating rods 17 both penetrate through and extend into the box body 7.

[0047] In the present invention, the electric heating rod 17 can heat the air sprayed onto the surface of the Mylar sheet after being turned on. The heated air will heat the Mylar sheet. By heating the Mylar sheet, its flexibility can be increased, stress concentration during bending can be reduced, and the risk of breakage can be reduced.

[0048] See also Figure 6 , wherein: one side of the clamping plate 5 is fixedly connected with an anti-skid pad 18, and the anti-skid pad 18 is a rubber layer.

[0049] In the present invention, the provision of the anti-skid pad 18 can increase the friction between the clamping plate 5 and the Mylar sheet, thereby improving the stability of clamping the Mylar sheet.

[0050] See also Figure 7 , wherein: a cylinder three 19 is embedded in the inner bottom wall of the groove 14, a top plate 20 is fixedly connected to the telescopic end of the cylinder three 19, and the outer side of the top plate 20 is slidably connected to the inner wall of the groove 14.

[0051] In the present invention, after the bending of the Mylar sheet is completed, the user turns on the cylinder three 19 to drive the top plate 20 to rise, and the top plate 20 can push the Mylar sheet out of the groove 14, and then the Mylar sheet can be clamped again by using the two clamping plates 5. The cylinder one 3 is turned on to drive the Mylar sheet to move to the right through the clamping plates 5, until the Mylar sheet moves to the top of the conveyor belt 2 on the left, and the cylinders one 3 are turned on one after the other to achieve the resetting of the clamping plates 5 and release the processed Mylar sheet. The bent Mylar sheet will fall onto the conveyor belt 2 on the left. Turning on the conveyor belt 2 on the left can drive the Mylar sheet to move to the front, thereby achieving the effect of unloading the Mylar sheet.

[0052] See also Figure 5 , wherein: a comparison module 21 is bidirectionally connected to the controller 10 , and a voltage regulation module 22 is bidirectionally connected to the controller 10 .

[0053] In the present invention, the setting of the comparison module 21 can compare the conditions of scratches and cracks on the front and back sides of the Mylar sheet. By turning on the motor 6, the side of the Mylar sheet with a worse condition is set downward. At this time, when the Mylar sheet is bent, the scratches are mainly subjected to compression force during the downward pressing of the pressing block 13. Compared with the tensile force, the compression force is less likely to cause the material to crack, thereby effectively reducing the occurrence of cracks in the Mylar sheet.

[0054] Moreover, when bending a Mylar sheet with many scratches on the surface that do not affect bending, the voltage regulating module 22 can reduce the voltage input to the electric push rod 12, thereby reducing the descending speed of the pressure block 13 to achieve the effect of slow bending. Slow bending can reduce stress concentration and avoid the occurrence of fractures caused by excessive stress at the scratches, thereby further reducing the occurrence of fractures in the Mylar sheet.

[0055] The above are only the preferred specific embodiments of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
