[0016] Compared with the existing technology, the present invention provides a fully automatic paper decal inspection machine with the following beneficial effects:

[0017] 1. This fully automatic decal inspection machine, through the rotation of a dual-axis motor and the setting of a negative pressure suction head, can automatically pick up and place stacked decals individually onto the conveyor belt. In combination with the setting of long and short linear guides, the inspection camera can fully and automatically inspect the entire sheet of decals, thereby effectively improving inspection efficiency.

[0018] 2. This fully automatic paper decal inspection machine utilizes a pull cord and piston plate. During the placement of the decals, the pull cord pulls the piston plate downward along the inner wall of the piston box, compressing the gas in the lower chamber of the piston box. After the decals are initially flattened, the gas is blown obliquely along the air holes toward the top surface of the paper. This utilizes the high-speed airflow to flatten the paper onto the conveyor belt, ensuring a flat lay and improving the accuracy of decal inspection.

[0019] 3. This fully automatic paper decal inspection machine uses a reset spring to generate negative pressure suction inside the piston box during paper decal removal. This suction is ultimately transmitted to the input end of the suction pipe, thereby drawing airflow around the inspection camera's searchlight end into the piston box, replenishing the airflow required for the next flattening operation. This effectively prevents dust from adhering to the inspection camera's searchlight end, ensuring the clarity of the camera's searchlight and thus improving the inspection accuracy of paper decals.

[0020] 4. This fully automatic paper decal inspection machine uses the cooperation of the limit pressure ring and the lifting cylinder to ensure that the paper decals stacked on the top of the supporting platform always maintain the same height, so as to cooperate with the negative pressure suction head to carry out multiple material removal operations.

[0032] Example:

[0033] Reference Figures 1-8The top of the two sets of side fixing plates 31 are symmetrically fixed on the side walls of the frame 1, and the conveyor belt 3 is fixed on the top of the multiple sets of side fixing plates 31, wherein both sides of the top of the frame of the conveyor belt 3 are fixedly connected with long linear guide rails 32, and the tops of the two sets of long linear guide rails 32 are slidably connected with short linear guide rails 33, and the short linear guide rails 33 are provided with a detection part for detecting the flower paper, a driving plate 4, and a dual-axis motor 41 is fixedly connected to the driving plate 4. The output ends of the dual-axis motor 41 on both sides are fixedly connected with a rotating box 42, and a material picking part for picking up the flower paper stacked on the carrying platform 22 is provided between the tops of the two sets of rotating boxes 42.

[0034] Reference Figure 2 、 Figure 5 、 Figure 7 and Figure 8 The feeding part includes a positioning shaft 6, which is fixedly connected between the rotating boxes 42 on both sides. Both sides of the positioning shaft 6 are rotatably connected with positioning blocks 61. The bottom of the positioning block 61 is fixedly connected to the feeding rack 62. A plurality of groups of negative pressure suction heads 63 are fixed at equal intervals on the feeding rack 62. A negative pressure pump 64 is fixedly connected to the feeding rack 62. The input end of the negative pressure pump 64 is communicated with the inner cavity of the negative pressure suction head 63. A blowing box 7 is fixedly connected to the side wall of the feeding rack 62. Blowing holes 71 are opened at equal intervals on the side wall of the blowing box 7, and an air guide for filling the blowing box 7 with air flow is provided on the rotating box 42. Two groups of blowing boxes 7 are provided, and the two groups of blowing boxes 7 are symmetrically distributed on both sides of the feeding rack 62. The two groups of blowing boxes 7 are used to apply uniform counterweight to the feeding rack 62, and two groups of corresponding inflation hoses 761 are also provided, and each group of inflation hoses 761 is provided with an electromagnetic valve.

[0035] Through the arrangement of the above structure, the dual-axis motor 41 is started to drive the rotating boxes 42 on both sides to rotate, so that the negative pressure suction head 63 moves to the front end of the top of the flower paper on the supporting platform 22, and then the negative pressure pump 64 is turned on to generate negative pressure suction in the negative pressure suction head 63, thereby adsorbing the front end of the flower paper on the multiple rows of negative pressure suction heads 63, and then the dual-axis motor 41 drives the rotating box 42 to rotate in the opposite direction, so that the adsorbed flower paper moves onto the conveyor belt 3. In this process, the counterweight effect of the material picking rack 62 and the blowing box 7 is utilized to make the positioning block 61 rotate along the positioning shaft 6, always keeping the negative pressure suction head 63 in a vertical downward state, and finally dragging the flower paper onto the conveyor belt 3.

[0036] Reference Figure 4, wherein the detection part includes a sliding plate 5, which is slidably connected to the short linear guide rail 33, a mounting rod 51 is fixedly connected to the top of the sliding plate 5, a detection camera 52 is fixedly connected to the end of the mounting rod 51, a telescopic cylinder 53 is fixedly connected to the side wall of the sliding plate 5, and a seal 531 is fixedly connected to the output end of the telescopic cylinder 53.

[0037] Through the arrangement of the above structure, after the decals are spread flat on the conveyor belt 3, the negative pressure suction in the negative pressure suction head 63 is released, so that the decals are spread flat on the conveyor belt 3, and then the controller 91 is used to make the sliding plate 5 slide on the short linear guide 33, and the short linear guide 33 slides on the long linear guide 32, so that the detection camera 52 can fully inspect the entire sheet of decals; at the same time, when unqualified decals appear, the telescopic cylinder 53 pushes the seal 531 to approach the top of the decal, and finally marks the top of the decal so that the operator can distinguish between qualified and unqualified products. Finally, the conveyor belt 3 is operated to bring out the inspected decals, and then the decal inspection work can be completed at once, effectively improving the efficiency of automated inspection.

[0038] Reference Figure 2 、 Figure 5 、 Figure 7 and Figure 8 , wherein the air guide part includes two side piston boxes 72, which are respectively fixed on the two side rotating boxes 42, and a piston plate 73 is slidably connected in the piston box 72. A return spring 731 is fixedly connected between the bottom of the piston plate 73 and the bottom of the piston box 72, and a pull rope 74 is fixedly connected to the bottom of the piston plate 73. A sealing ring 75 is fixedly connected between the pull rope 74 and the bottom of the piston box 72, and the other end of the pull rope 74 is fixed on the side fixed plate 31. An inflation tube 76 is fixed and connected between the lower parts of the side walls of the two groups of piston boxes 72, and an inflation hose 761 is fixedly connected to the top center of the inflation tube 76. The other end of the inflation hose 761 is connected to the inner cavity of the blowing box 7, and a one-way valve is provided in the inflation tube 76.

[0039] It should be noted that the one-way valve in the inflation tube 76 can only allow the gas in the piston box 72 to enter the blowing box 7.

[0040] Through the arrangement of the above structure, in the process of rotating box 42 rotating toward the top of conveyor belt 3, the distance between piston box 72 and the fixed end of pull rope 74 will gradually increase. At this time, pull rope 74 will pull piston plate 73 to slide downward along the inner wall of piston box 72, thereby compressing the gas in the lower cavity of piston box 72. When the flower paper moves into place, the solenoid valve in the inflation hose 761 on the side away from the detection camera 52 is opened. Under the action of high-pressure gas, the one-way valve in the inflation tube 76 will be pushed open, allowing the gas to enter the blowing box 7 along the inflation tube 76 and the inflation hose 761, and finally blown obliquely along the blowing hole 71 toward the top of the flower paper, thereby utilizing the action of high-speed airflow to flatten the flower paper on conveyor belt 3, ensuring the flattening effect of the flower paper and improving the accuracy of flower paper detection.

[0041] Reference Figure 2-Figure 5 and Figure 7 , wherein, the output ends on both sides of the dual-axis motor 41 are rotatably connected to the positioning frames 43, and the other ends of the two groups of positioning frames 43 are fixed on the corresponding side fixing plates 31, and the positioning frames 43 are fixedly connected to the air guide columns 44, and the air guide rings 441 are rotatably connected to the air guide columns 44, and the air guide rings 441 are connected to the inner cavities of the air guide columns 44, and the mounting rod 51 is fixedly connected to the air intake pipe 81, and the lower parts of the side walls of the two groups of piston boxes 72 are fixed and connected to the air intake pipe 81, and the other ends of the air intake pipe 81 are fixedly connected to the air guide ring 441, and the air intake pipe 81 is connected to the inner cavity of the air guide ring 441, and the ends of the air guide columns 44 on both sides are fixed and connected to the air collecting pipe 82, and the air collecting pipe 82 is fixed and connected to the air guide pipe 83, and the other end of the air guide pipe 83 is connected to the air intake pipe 8, and the input end of the air intake pipe 8 faces the searchlight end of the detection camera 52, and a one-way valve is provided in the air intake pipe 8.

[0042] It should be noted that the one-way valve in the air intake pipe 8 can only allow external airflow to enter the piston box 72.

[0043] When the cam 72 is in the air, the cam 73 is in the air, and the air is sucked out of the air filter 76, so that the cam 73 is in the air, and the air is sucked out of the air filter 76. When the cam 72 is in the air, the cam 73 is in the air, and the air is sucked out of the air filter 76, the cam 73 is in the air, and the air is sucked out of the air filter 76. When the cam 72 is in the air, the cam 73 is in the air, and the air is sucked out of the air filter 76, the cam 73 is in the air, and the air is sucked out of the air filter 76.

[0044] Reference Figure 2 、 Figure 5 and Figure 6 , wherein the limiting part includes four groups of limiting plates 23, which are all fixed on the top of the mounting plate 2, and the four groups of limiting plates 23 are distributed at the corners of the supporting platform 22 close to the conveyor belt 3. A plurality of groups of limiting guide rods 24 are symmetrically fixed to the bottom of the supporting platform 22, and the bottom ends of the limiting guide rods 24 extend through and extend to the bottom of the mounting plate 2; an adjusting rod 25 is fixedly connected to the top of the mounting plate 2, and a mounting piece 251 is fixedly sleeved on the adjusting rod 25, and a micromotor 26 is fixedly connected to the mounting piece 251, and the end of the micromotor 26 is fixedly connected to a limiting pressure ring 261; by utilizing the cooperation of the limiting pressure ring 261 and the lifting cylinder 21, the flower paper stacked on the top of the supporting platform 22 can always be kept at the same height, so as to cooperate with the negative pressure suction head 63 to perform multiple material picking operations.

[0045] Reference Figure 1 A shell 9 is provided on the outer side of the frame 1, and a controller 91 is provided on the shell 9. The controller 91 is electrically connected to each group of electrical components provided on the frame 1; the controller 91 is used to electrically control each group of electrical components to realize the automatic operation of the equipment, thereby effectively improving the detection efficiency.

[0046] Reference Figures 1-8 Then, the double-axis motor 41 is started to drive the rotating boxes 42 on both sides to rotate, so that the negative pressure suction head 63 moves to the front end of the top of the flower paper on the supporting platform 22, and then the negative pressure pump 64 is turned on to generate negative pressure suction in the negative pressure suction head 63, thereby adsorbing the front end of the flower paper on the multiple rows of negative pressure suction heads 63, and then the double-axis motor 41 drives the rotating box 42 to rotate in the opposite direction, so that the adsorbed flower paper moves onto the conveyor belt 3, and in this process, the counterweight effect of the material picking rack 62 and the blowing box 7 is used to make the positioning block 61 rotate along the positioning shaft 6, always keeping the negative pressure suction head 63 in a vertical downward state, and finally dragging the flower paper onto the conveyor belt 3.

[0047] Next, the negative pressure suction in the negative pressure suction head 63 is released, so that the decal paper is spread flat on the conveyor belt 3. Then, through the controller 91, the sliding plate 5 slides on the short linear guide 33, and the short linear guide 33 slides on the long linear guide 32, so that the detection camera 52 can fully inspect the entire decal paper. At the same time, when unqualified decal paper appears, the telescopic cylinder 53 pushes the seal 531 to approach the top of the decal paper and finally marks the top of the decal paper so that the operator can distinguish between qualified and unqualified products. Finally, the conveyor belt 3 is operated to bring out the inspected decal paper, and then the decal paper inspection work can be completed at once, effectively improving the efficiency of automated inspection.

[0048] In addition, as the rotating box 42 rotates toward the top of the conveyor belt 3, the distance between the piston box 72 and the fixed end of the pull rope 74 will gradually increase. At this time, the pull rope 74 will pull the piston plate 73 to slide downward along the inner wall of the piston box 72, thereby compressing the gas in the lower cavity of the piston box 72. When the flower paper moves into place, the solenoid valve in the inflation hose 761 on the side away from the detection camera 52 is opened. Under the action of high-pressure gas, the one-way valve in the inflation tube 76 will be pushed open, allowing the gas to enter the blowing box 7 along the inflation tube 76 and the inflation hose 761, and finally blown obliquely along the blowing hole 71 toward the top of the flower paper, thereby utilizing the action of high-speed airflow to flatten the flower paper on the conveyor belt 3, ensuring the flattening effect of the flower paper and improving the accuracy of flower paper detection. The cam 73 is then released to the air filter 76, which in turn releases the air from the air filter 77. The cam 73 is then released to the air filter 76, which in turn releases the air from the air filter 77. The cam 73 is then released to the air filter 76, which in turn releases the air from the air filter 77.
