Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the utility model.

[0032] Embodiment one:

[0033] Reference Figure 1 A full-automatic feeding and discharging nameplate visual detection device, including control cabinet 10, feeding mechanism 11, conveying mechanism 12, visual detection machine 13, display screen 14, material taking mechanism 15, transport mechanism 16, discharging mechanism 17 and material 20, the left side of control cabinet 10 is installed with feeding mechanism 11, one side of feeding mechanism 11 is installed with discharging mechanism 17, one side of discharging mechanism 17 is installed with conveying mechanism 12, conveying mechanism 12 contains several strip belts 121, conveying mechanism 12 is installed with visual detection machine 13, the right end of conveying mechanism 12 is installed with material taking mechanism 15, one side of material taking mechanism 15 is installed with transport mechanism 16 below, visual detection machine 13 is installed with display screen 14.

[0034] In the above scheme, first, material 20 is placed and stacked on feeding mechanism 11, and feeding mechanism 11 transports material 20 to discharging mechanism 17; then, material 20 on feeding mechanism 11 is taken out by discharging mechanism 17, and material is placed on conveying mechanism 12 by discharging mechanism 17, and strip belt 121 on conveying mechanism 12 transports material 20 through visual detection machine 13 below, and visual detection machine 13 scans and identifies on display screen 14; then, material 20 after scanning and identifying by visual detection machine 13 is transported to one side of material taking mechanism 15 by conveying mechanism 12, and material 20 on conveying mechanism 12 is taken down by material taking mechanism 15; finally, material 20 is placed on the surface of transport mechanism 16 by material taking mechanism 15.

[0035] Note that: conveying mechanism 12 is mainly composed of a plurality of belts, transport mechanism 16 is composed of an entire belt cloth, conveying mechanism 12 and transport mechanism 16 are attached with corresponding driving devices for driving the movement of the belt. The whole working process is automatically controlled by control cabinet 10, and PLC automatic control program is used to control the whole working process. Visual detection machine 13 uses advanced image acquisition device (such as industrial camera) and image processing system to complete identification.

[0036] Reference Figures 1-5, the feeding mechanism 11 comprises a conveying belt 111 installed above the console 10, a partition plate 112 is installed above the conveying belt 111, an L-shaped push plate 113 is installed on the conveying belt 111, and the material 20 is placed on the L-shaped push plate 113.

[0037] In the above scheme, the partition plate 112 is provided with two groups, each group of partition plates 112 is two partition plates 112, and each group of partition plates 112 is used for placing the material 20, and the transportation of the conveying belt 111 drives the displacement of the L-shaped push plate 113, so as to push the material 20 on the conveying belt 111 to the direction of the discharging mechanism 17. It should be noted that the conveying belt 111 is provided with a motor for driving the rotation of the conveying belt 111, which is not explicitly shown in the figure.

[0038] Reference Figure 4 and Figure 5 The discharging mechanism 17 comprises an axis plate 174, one end of the axis plate 174 is provided with a gearbox 172, the gearbox 172 is provided with a first motor 171, an output end of the gearbox 172 is provided with a transmission shaft 173, two swing arms 175 are installed on the transmission shaft 173, one end of the swing arm 175 is provided with a mounting plate 176, and a negative pressure suction cup 177 is installed on one side of the mounting plate 176.

[0039] In the above scheme, Figure 4 is a discharging diagram of the discharging mechanism 17, Figure 5 is a material taking diagram of the discharging mechanism 17. The conveying belt 111 transports the material 20 close to the discharging mechanism 17, the PLC automatic control program automatically controls the first motor 171 to start, the power output of the first motor 171 is given to the gearbox 172, the transmission shaft 173 is driven by the gearbox 172, the rotation of the transmission shaft 173 changes the angle of the swing arm 175 (refer to Figure 5 ), the negative pressure suction cup 177 sucks the material 20 on the L-shaped push plate 113, at this time, when the negative pressure suction cup 177 sucks the material 20, the first motor 171 is reversed (refer to Figure 4 ), the negative pressure suction cup 177 rotates to below the belt on the conveying mechanism 12, the material 20 contacts the belt and is separated from the negative pressure suction cup 177, so that the material is placed on the conveying mechanism 12 for transportation, that is, the material 20 passes below the visual inspection machine 13 and completes the detection. It should be noted that when the negative pressure suction cup 177 sucks a material 20, the conveying belt 111 starts to rotate, and the L-shaped push plate 113 displaces a small distance; here the start of the conveying belt 111 is intermittent, and the negative pressure suction cup 177 needs to suck a material 20, so that the conveying belt 111 starts to rotate, thereby making up the vacancy caused by the last material 20, so as to accurately adsorb the material 20.

[0040] Further, two negative pressure suction cups 177 are arranged side by side on the mounting plate 176. With the arrangement of two negative pressure suction cups 177, when the area of the material 20 is too high, the upper negative pressure suction cup 177 can assist in sucking the material 20, improving the stability of the material sucking. Conversely, when the area of the material 20 is small, only one negative pressure suction cup 177 below is needed to suck.

[0041] Further reference Figure 4 and Figure 5 When the material 20 is placed, the back is towards the negative pressure suction cup 177, the slitting belt 121 is equidistantly arranged on the conveying mechanism 12, and the swing arm 175 is hidden between the slitting belts 121.

[0042] In a further embodiment, the back of the material 20 faces the negative pressure suction cup 177 (as shown in Figure 5 ), that is, the surface of the negative pressure suction cup 177 is adsorbed on the back of the material 20; at the same time, since the swing arm 175 is hidden between the slitting belts 121 (refer to Figure 4 ), when the swing arm 175 is turned over, the front of the material 20 will be upwards, and the back of the material 20 will be in contact with the slitting belt 121, thereby completing the material removal, that is, the material 20 is transported on the slitting belt 121.

[0043] This further scheme ingeniously realizes the contact between the negative pressure suction cup 177 and the back of the material 20, and at the same time realizes the upward of the front of the material 20, which is convenient for the visual inspection machine 13 to detect without obstruction. The back of the material 20 faces the negative pressure suction cup 177, and the front of the material 20 is upwards when placed, so as to protect the detection surface from secondary damage.

[0044] Reference Figure 2 , Figures 6-8 The taking mechanism 15 comprises a first track 151 symmetrically arranged above the console 10, a first sliding block 152 slidingly installed on the first track 151, a horizontal arm 153 installed on the first sliding block 152, a connecting plate 154 installed at the middle part of the horizontal arm 153, a second track 155 installed on the connecting plate 154, a second sliding block 156 slidingly installed on the second track 155, an extension arm 157 centrally installed on the second sliding block 156, vertical plates 158 perpendicularly installed on both sides of the extension arm 157, a metal frame 159 installed below the vertical plates 158, and a taking disc 1591 installed on the metal frame 159.

[0045] In the above scheme, the first sliding block 152 and the second sliding block 156 are linear motors, and reference Figure 6When the material 20 passes under the visual inspection machine 13 and the detection is completed, the material 20 continues to be transported by the conveying mechanism 12 to the vicinity of the material taking mechanism 15. When the material taking mechanism 15 takes the material: the second sliding block 156 is started to move upward, i.e. to drive the lower material taking disc 1591 to move, and then the first sliding block 152 is started to transport the second sliding block 156 to the upper side of the material 20; then the second sliding block 156 is started to slide downward, so that the material taking disc 1591 contacts and adsorbs the material 20; after the material taking disc 1591 adsorbs the material 20, the first sliding block 152 is started to drive the second sliding block 156 to move close to the conveying mechanism 16, and finally the second sliding block 156 is started to place the material 20 adsorbed by the material taking disc 1591 on the conveying mechanism 16, and the conveying mechanism 16 completes the final transportation to perform subsequent packaging or packaging operations.

[0046] Embodiment two (in combination with embodiment one):

[0047] With reference to Figures 5-7 The two ends of the second track 155 are provided with first installation boxes 1552, one side of each first installation box 1552 is provided with a first belt box 1553, one end of the first belt box 1553 is provided with a second motor 1551, and a rotating wheel 1555 is installed in the first installation box 1552, a conveying belt 1554 is wound on the rotating wheel 1555, the second sliding block 156 is connected with the conveying belt 1554, and one end of the rotating wheel 1555 is connected with the output end of the second motor 1551 through a belt.

[0048] In the above scheme, one end of the rotating wheel 1555 is connected with the output end of the second motor 1551 through a belt, the belt is installed in the first belt box 1553, and a belt transmission mode is adopted to replace a linear motor to drive the displacement of the second sliding block 156.

[0049] Further, the two ends of the first track 151 are provided with second installation boxes 1521, one end of each second installation box 1521 is provided with a second belt box 1522, one end of the second belt box 1522 is provided with a third motor 1523, a rotating wheel 1555 is installed in the second installation box 1521, and a synchronous shaft 1524 is connected to one end of the rotating wheel 1555.

[0050] In a further embodiment, the two ends of the second installation box 1521 are linked through the synchronous shaft 1524 to improve the stability of the first sliding block 152 on both sides, and the output end of the third motor 1523 is also connected with the rotating wheel 1555 through a belt, the third motor 1523 is started to drive the synchronous shaft 1524 to rotate, the synchronous shaft 1524 drives the rotating wheels 1555 at both ends to rotate, and the conveying belt 1554 on the rotating wheel 1555 drives the first sliding block 152 to move.

[0051] Finally, the negative pressure suction disc 177 and the material taking disc 1591 in the utility program adopt negative pressure material taking technology. The negative pressure generated by the vacuum pump or air compressor forms a vacuum state inside the suction disc. When the suction disc contacts and seals the material, the air inside the suction disc is extracted to form a negative pressure environment. At this time, the atmospheric pressure outside the suction disc is greater than the pressure inside the suction disc, thereby generating an inward pressure difference. This pressure difference is sufficient to overcome the gravity or other external force of the adsorbed material, so that the material is firmly adsorbed on the suction disc.

[0052] The entire material processing process is automatically operated through the PLC automatic control program, reducing manual intervention, improving production efficiency, and reducing production cost. From the transportation, suction, unloading, placement to the final transportation of the material, each step is automatically completed by mechanical equipment, ensuring the continuity and stability of the process. The material passes through the visual inspection machine during the conveying process, realizing online monitoring of the material quality, which helps to timely discover and handle unqualified materials and ensure product quality.

[0053] The specific implementation process of the utility model is as follows:

[0054] Step one: the transportation of the conveying belt 111 will drive the L push plate 113 to displace, thereby pushing the material 20 on the conveying belt 111 in the direction of the unloading mechanism 17.

[0055] Step two: the PLC automatic control program automatically controls the first motor 171 to start, and the power output of the first motor 171 is given to the gearbox 172, which drives the transmission shaft 173, and the rotation of the transmission shaft 173 changes the angle of the swing arm 175 (reference Figure 5 The negative pressure suction disc 177 will suck the material 20 on the L push plate 113, and at this time the negative pressure suction disc 177 sucks the material 20, the first motor 171 is reversed (reference Figure 4 ), the negative pressure suction disc 177 rotates to the below of the belt on the conveying mechanism 12, the material 20 contacts the belt and separates from the negative pressure suction disc 177, so that the material is placed on the conveying mechanism 12 for transportation, that is, the material 20 passes below the visual inspection machine 13 and completes the detection.

[0056] Step three: the material 20 continues to be transported by the conveying mechanism 12 to be close to the material taking mechanism 15.

[0057] Step four: when the taking mechanism 15 takes the material, the second sliding block 156 starts to displace upward, i.e. drives the lower taking tray 1591 to displace, then the first sliding block 152 starts to transport the second sliding block 156 to above the material 20; then the second sliding block 156 starts to slide downward, so that the taking tray 1591 contacts and adsorbs the material 20; when the taking tray 1591 adsorbs the material 20, the first sliding block 152 starts to drive the second sliding block 156 to move close to the transporting mechanism 16, and finally the second sliding block 156 starts to place the material 20 adsorbed by the taking tray 1591 on the transporting mechanism 16.

[0058] Step five: the transporting mechanism 16 completes the final transportation to carry out subsequent packaging or packaging work.

[0059] Step six: repeating steps one to five.
