The lifting platform 11 can be selected to be parallel to the bottom surface of the collection box 1, and the lifting platform 11 can be selected to move in the vertical direction inside the collection box 1, and the works to be collected are stacked on the lifting platform 11.

[0032] The above-mentioned grasping component 3 can be specifically selected as a panel with a negative pressure adsorption tube. The work is connected to the panel through the negative pressure adsorption tube. The panel is flipped 180° so that the work faces the camera 21. Of course, the grasping component 3 can also be selected as a robot. The robot has four adsorption devices. The four adsorption devices are connected to the four corners of the work on the lifting platform 11. The robot is flipped so that the work faces the camera 21.

[0033] The above-mentioned controller 4 can be connected to the camera 21, lifting platform 11 and grabbing component 3 through data cables and wires. Of course, the controller 4 can also be connected to the camera 21, lifting platform 11 and grabbing component 3 through a local wireless network, so that the controller 4 can send control signals to the camera 21, lifting platform 11 and grabbing component 3.

[0034] During specific use, the side of the artwork with the picture is regarded as the front side, and the front sides of the artworks are stacked downwards to form a artwork group, and the artwork group is placed on the lifting platform 11. The controller 4 controls the lifting platform 11 to rise in the collection box 1, so that the artwork group is close to the grabbing component 3. The grabbing component 3 grabs the artwork on the top of the artwork group in the lifting platform 11, and the lifting platform 11 descends. The grabbing component 3 flips over, and the artwork flips upward with the grabbing component 3, and the front side of the artwork faces the camera 21. The controller 4 controls the camera to take a picture of the artwork. After taking the picture, the grabbing component is flipped over again. When the artwork forms a 45° angle with the pick-up and drop window, the grabbing component 3 releases the artwork, and the artwork floats out of the pick-up and drop window and out of the collection box 1. The lifting platform 11 rises again to repeat the photo-taking operation.

[0035] By setting up a collection box 1, a lifting platform 11, a camera 21, a grabbing assembly 3 and a controller 4, a pick-up and drop window is provided on the side of the collection box 1, and the lifting platform 11, the camera 21 and the grabbing assembly 3 are all located inside the collection box, and the camera 21 is located on the top of the collection box 1, the lifting platform 11 is located below the camera 21, and is used to fix the works to be collected and drive the works to be collected to move up and down, the grabbing assembly 3 is rotatably set between the lifting platform 11 and the camera 21, and is used to grab and flip the works to be collected on the lifting platform; at the same time, the controller 4 is connected to the camera 21, the lifting platform 11 and the grabbing assembly 3 to control the actions of the camera 21, the lifting platform 11 and the grabbing assembly 3, and finally the stacked works of art are close to the grabbing assembly 3 on the lifting platform 11, the grabbing assembly 3 grabs the back of the topmost work of art and flips it so that the front of the work of art faces the camera 21 to complete the shooting of the work of art, thereby realizing the automatic shooting and collection of the work of art and improving the efficiency of the collection of the work of art.

[0036] Reference Figure 1 、 Figure 2 and Figure 3As shown, in some embodiments, the gripping assembly 3 includes a carrier plate 31, an adsorption device, and a sensing device. The carrier plate 31 is rotatably connected to the collection box 1 and can rotate at least 180° relative to the collection box 1. The adsorption device is provided on the carrier plate 31, and the sensing device is located inside the collection box 1, suitable for sensing the distance between the carrier plate 31 and the lifting platform 11, and sending a signal to the controller 4 to control the operation of the carrier plate 31 and the adsorption device. Specifically, the carrier plate 31 can be selected as a rectangular panel, and the carrier plate 31 is arranged in the collection box 1 parallel to the bottom surface of the collection box 1. The opposite side edges of the carrier plate 31 are rotatably connected to the side walls of the collection box 1, so that the carrier plate 31 can rotate at least 180° relative to the collection box 1, thereby completing the flipping action of the carrier plate 31. The camera 21 can be selected to be located directly above the center of the carrier plate 31 so that the shooting area of ​​the camera 21 covers the carrier plate 31.

[0037] The aforementioned adsorption device can be a fan. When the fan is brought close to the artwork, it is turned on, creating a negative pressure between the fan and the artwork, causing the fan to adsorb the artwork. Five fans can be installed on the carrier plate 31, with one fan located in the center of the carrier plate 31 and the remaining fans located at the four corners of the carrier plate 31. The fans blow air toward the carrier plate 31, so that the side away from the carrier plate 31 can generate negative pressure to adsorb the artwork. Of course, other numbers of fans can be installed on the carrier plate 31, as long as the fans can stably adsorb the artwork to the carrier plate 31 after activation.

[0038] The above-mentioned sensing device can be selected as a laser distance sensor, and the sensing device can be selected to be set on the carrier plate 31, so as to detect the distance between the carrier plate 31 and the artwork stacked on the lifting platform 11. Of course, the sensing device can also be selected to be set on the collection box 1, and the sensing device can be selected to be connected to the collection box 1 by bolts. The distance between the sensing device and the bottom surface of the collection box 1 is equal to the distance between the carrier plate and the bottom surface of the collection box 1.

[0039] The controller 4 can receive a signal from the sensing device to raise the lifting platform 11. When the artwork on the lifting platform 11 approaches the carrier 31, the controller 4 stops the movement of the lifting platform 11, activates the adsorption device to adsorb the artwork onto the carrier 31, and then controls the carrier 31 to rotate 180° so that the front of the artwork faces the camera 21, thereby enabling the camera 21 to capture an image of the artwork.

[0040] By setting a carrier plate 31, an adsorption device and a sensing device as a grasping component 3, the carrier plate 31 is rotatably connected to the collection box 1, so that the carrier plate 31 can be rotated at least 180° relative to the collection box 1, thereby giving the carrier plate 31 a flipping function, and the adsorption device is set on the carrier plate 31, so that the adsorption device can adsorb and connect the art work to the carrier plate 31. The sensing device is located inside the collection box 1, suitable for sensing the distance between the carrier plate 31 and the lifting platform 11, and sending a signal to the controller 4 to control the carrier plate 31 and the adsorption device to operate, and finally the art work is connected to the carrier plate 31 through the adsorption device. The adsorption device adsorbs the back of the art work to avoid damaging the art work. After adsorbing the art work, the carrier plate 31 rotates 180°, so that the front of the art work faces the camera 21, realizing the automatic collection of the art work image.

[0041] Reference Figure 1 、 Figure 2 and Figure 3 As shown, in some embodiments, the adsorption device includes multiple adsorption fans 32, one of which is arranged at the center of the carrier plate 31, and the remaining adsorption fans 32 are arranged at least one circle around the center of the carrier plate. Specifically, an adsorption fan 32 can be connected to the center of the carrier plate 31 by bolts as a main fan, and multiple adsorption fans 32 can be arranged around the main fan as a first adsorption fan group, and multiple adsorption fans 32 can be arranged around the first adsorption fan group as a second adsorption fan group. Specifically, the first adsorption fan group can be selected to have four adsorption fans 32, and the second adsorption fan group can be selected to have four adsorption fans 32. Of course, the first adsorption fan group can also be selected to have four adsorption fans and the second adsorption fan group can be selected to have six adsorption fans. It can be understood that multiple adsorption fans 32 can be selected to be arranged around the second adsorption fan group as a third adsorption fan group, and the number of adsorption fan groups can be reasonably set according to the size of the paper in actual use.

[0042] The above-mentioned adsorption fan 32 can be selectively controlled by the controller 4. When the paper size of the work to be collected is large, the controller 4 controls the main fan, the first adsorption fan group and the second adsorption fan group to start, so that the contact positions of the adsorption fan 32 and the paper are evenly distributed on the paper, thereby improving the stability of multiple adsorption fans 32 when adsorbing the paper to the carrier plate 31; and the controller 4 can also control the speed of the adsorption fan 32. When the paper thickness is large, the speed of the adsorption fan 32 is accelerated, thereby improving the stability of the connection between the adsorption fan 32 and the art work.

[0043] The adsorption device includes a plurality of adsorption fans 32, one of which is disposed at the center of the carrier plate 31, and the remaining adsorption fans 325 are disposed at least around the center of the carrier plate 31.

[0044] The adsorption fan 32 at the center of the carrier plate 31 is arranged around the center of the carrier plate 31 for a circle, so that the adsorption fan 32 can adsorb the center of the artwork. The multiple adsorption fans 32 arranged around the center of the carrier plate 31 for at least a circle can adsorb the rest of the artwork at multiple points, ensuring the stability of the connection between the artwork and the carrier plate 31 through the adsorption device.

[0045] When multiple adsorption fans 32 are arranged around the center of the carrier plate 31 for multiple circles, it is suitable for adsorbing papers of different sizes, thereby improving the adaptability of the adsorption device to papers of different sizes.

[0049] The carrier plate 31 can be driven to rotate, and the rotating motor 34 is connected to the controller 4 , so that the controller 40 can control the rotation angle of the carrier plate 31 through the rotating motor 34 .

[0050] By setting up a rotation mechanism, connecting the rotation mechanism to the carrier 31 so that it is suitable for driving the carrier 31 to rotate, and connecting the rotation mechanism to the controller 4, the controller 4 can finally control the rotation angle of the carrier 31 by controlling the rotation mechanism, thereby realizing the automatic control of the rotation of the carrier 31 by the controller 4.

The blowing direction of the blowing fan 33 points to the pick-and-place window. Specifically, the blowing fan 33 can be set on the side of the carrier plate 31 provided with the adsorption device. When the adsorption fan 32 is downward, two blowing fans 33 can be set on the edge of the side of the carrier plate 31 close to the pick-and-place window. When the carrier plate 31 is turned over after adsorbing the artwork through the adsorption device, the blowing direction of the blowing fan 33 is in the direction of the pick-and-place window. Of course, the blowing fan 33 can also be set on the side of the collection box 1 opposite to the pick-and-place window.

[0053] By configuring the grabbing assembly 3 to also include a plurality of blowing fans 33, the blowing fans 33 are arranged at the edge of the carrier plate 31, or the blowing fans 33 are arranged in the collection box 1, and the blowing direction of the blowing fans 33 is directed toward the pick-up and placement window. Finally, after the artwork on the carrier plate 31 is collected, the adsorption device stops working, and the blowing fans 33 are started to blow the artwork out of the pick-up and placement window through air flow, thereby realizing the function of automatically detaching the artwork from the carrier plate 31 after the artwork is photographed.

Of course, a slide rail can also be selected to be set on the lifting platform 11, and the bottom of the positioning member 12 can be inserted into the slide rail to make the positioning member 12 slidably connected to the slide rail.

[0066] By arranging multiple positioning members 12 on the lifting platform 11, the multiple positioning members 12 are arranged around the center of the lifting platform 11, and the multiple positioning members 12 can slide toward the center of the lifting platform 11. When the art work is placed at the center of the lifting platform 11, the positioning members 12 slide toward the center of the lifting platform 11 to limit the position of the art work, thereby preventing the art work from moving due to vibration during the lifting process of the lifting platform 11, which affects the image acquisition quality of the subsequent art work.

[0067] Reference Figure 1 、 Figure 2 、 Figure 4 and Figure 5 As shown, in some embodiments, the positioning member 12 includes a limiting panel 122, a guide plate 123 and a sliding portion 121. A plurality of slide rails 124 are provided on the lifting platform 11, at least two slide rails 124 are perpendicular to each other, the sliding portion 121 is slidably connected to the slide rails 124, the limiting panel 122 is arranged on the sliding portion 121, the limiting panel 122 is perpendicular to the lifting platform 11, the guide plate 123 is arranged at the end of the limiting panel away from the lifting platform 11, and the guide plate 123 is inclined in the direction away from the center of the lifting platform 11.

[0068] Specifically, when the lifting platform 11 is a rectangular panel, one slide rail 124 can be set along the length direction of the lifting platform 11, and two slide rails 124 can be set along the width direction of the lifting platform 11. One end of the slide rail 124 along the width direction is connected to the slide rail 124 set along the length direction, and the other end is connected to one side edge of the lifting platform 11.

[0069] The above-mentioned limiting panel 122 can be selected as a rectangular panel, the limiting panel 122 is perpendicular to the lifting platform 11, the sliding part 121 can be selected as two sliding panels set at the bottom of the limiting panel 122, the two sliding panels are arranged opposite to each other, and when the sliding part 121 is connected to the slide rail 124, the slide rail 124 is located between the two sliding panels, and the guide plate 123 can be selected as a panel with a rectangular structure. Of course, it can also be selected as a semicircular panel, and the straight side edge of the semicircular panel is connected to the side edge of the top of the limiting panel 122, as long as the artwork reaches the position of the limiting panel 122 under the guidance of the guide plate 123.

[0070] By setting a limit panel 122, a guide plate 123 and a sliding part 121 as the positioning member 12, and providing a plurality of slide rails 124 on the lifting platform 11, at least two slide rails 124 are perpendicular to each other, and the sliding part 121 is slidably connected to the slide rails 124, and the limit panel 122 is set on the sliding part 121, and the limit panel 122 is perpendicular to the lifting platform 11, and the guide plate 123 is set at the end of the limit panel away from the lifting platform 11, and the guide plate 123 is inclined in the direction away from the center of the lifting platform 11, so that after the art work is placed on the guide plate 123, it will slide into the position of the limit panel 122 under the action of gravity, and at least two mutually perpendicular slide rails 124 are set on the lifting platform 11, so that when multiple positioning members 12 are set on the slide rails 124, they can slide relatively along the slide rails 124, thereby achieving the effect of multiple positioning members 12 limiting the position of the art work on the lifting platform 11.

[0071] In some embodiments, a paper sensor is further provided in the lifting platform 11, which is suitable for sensing the amount of paper in the lifting platform 11 and sending a signal to the controller 4. Specifically, the paper sensor can be selected to be installed on the lifting platform 11 by bolts. The paper sensor can be a laser sensor. When a work of art is placed on the lifting platform 11, the laser sensor is blocked. After the work of art is collected, there is no obstruction on the laser sensor, so it sends a signal to the controller 4 to stop the lifting action of the lifting platform 11. Of course, a paper sensor visual sensor can also be selected to set an identification mark on the work of art. When the visual sensor recognizes the identification mark, the lifting platform 11 works normally. When the visual sensor does not recognize the identification mark, the controller 4 controls the lifting platform 11 to stop working.

[0072] By also providing a paper sensor in the lifting platform 11, which is suitable for sensing the amount of paper on the lifting platform 11 and sending a signal to the controller 4, the controller 4 can control the lifting platform 11 to move normally when paper is placed on the lifting platform 11. When all the works of art on the lifting platform 11 have completed the image acquisition operation, the controller 4 controls the lifting platform 11 to stop working, thereby improving the degree of automation of the lifting platform 11.

[0073] The controller 4 may specifically include a PLC controller and a touch screen. The PLC controller is connected to the camera 21, the telescopic rod 211, the suction device, the air blower 33, the rotation mechanism, and the fill light device 22. The touch screen is connected to the PLC controller so that the touch screen sends signals to the PLC controller to control the camera 21's photo function, the extension and retraction of the telescopic rod 211 to control the camera 21's focus, the suction device to control the attachment and detachment of the artwork on the carrier plate 31, the activation of the air blower 33 to allow the artwork to float out of the collection box 1 through the access window, the rotation mechanism to control the rotation angle of the carrier plate 31, and the brightness of the fill light device 22 to control the exposure of the artwork. The PLC controller may be located inside the collection box 1, or may be located outside the collection box 1. The touch screen may be located outside the collection box 1 to facilitate the staff in sending signals to the PLC controller.

[0074] When in use, the front of the artwork to be inspected is stacked downward to form a group of artworks, and the group of artworks is placed on the lifting platform 11. The positioning member 12 is slid so that the group of artworks is located between the multiple positioning members 12 to maintain a stable position. The touch screen is operated to run the program, and the lifting platform 11 rises and gradually approaches the carrier 31. After the sensing device senses the lifting platform 11, it sends a signal to the controller 4, and the lifting platform 11 stops rising; multiple adsorption fans 32 are started, and the back of the artwork on the top layer of the group of artworks is adsorbed and connected to the carrier 31. The lifting platform 11 descends to the initial position, and the rotation mechanism is started to make the carrier 31 rotate 180 degrees. The front of the artwork faces the camera 21. After focusing by controlling the telescopic rod 211 and controlling the fill light device 22 for fill light, the camera 21 performs an image acquisition operation on the artwork. After the image acquisition is completed, the rotating mechanism rotates the carrier plate 31 45 degrees, causing the carrier plate 31 to tilt toward the side close to the pick-up and placement window. The adsorption fan 32 stops working and the blowing fan 33 starts at the same time. The artwork floats out of the pick-up and placement window and into the storage basket under the action of wind and its own gravity. The carrier plate 31 continues to rotate back to the initial state, and the lifting platform 11 rises. The above operation is repeated to capture the artwork in the artwork group.

[0075] When all the artworks on the lifting platform 11 have completed the image acquisition operation, the paper sensor sends a signal to the controller 4, the lifting platform 11 stops working, and the touch screen reminds the staff to put in a new group of artworks to be collected.
