The automatic detection device 200 is used to automatically detect the material 2 to be detected transferred from the assembly line 400, and transmit the detection result to the control device 202. The material 2 after detection is transferred to the assembly line 400 again, and the material after detection is transferred to the automatic material receiving device 300 through the assembly line 400. The automatic material receiving device 300 automatically classifies and outputs the material 2 after detection according to the detection result of the control device 202.

[0031] Please also read Figures 2 to 5, are schematic diagrams of the three-dimensional structure of the automatic loading device 100 of the present invention at different angles and schematic diagrams omitting some structures, respectively. As shown in the figure, the automatic loading device 100 includes a frame body 10, a material storage turntable 20, a turntable power device 30, a turntable positioning device 40, a material lifting device 50 and a material conveying device 60. The frame body 10 is used to fix the material storage turntable 20, the turntable power device 30 and the turntable positioning device 40; the material storage turntable 20 is used to store the material 2 to be conveyed, and the material lifting device 50 is used to lift the material 2 to be detected upward to lift the material 2 to a suitable position to facilitate the material conveying device 50 to take the material. The turntable power device 30 is used to provide power when the material storage turntable 20 needs to rotate, and the turntable positioning device 40 is used to fix the material storage turntable 20 when the material storage turntable 20 needs to be fixed, and the material conveying device 60 is used to convey the material 2 to be detected in the material storage turntable 20 to the automatic detection device 200 for detection.

[0032] Among them, the frame body 10 includes a load-bearing plate 12 and four support columns 14 for supporting and fixing the load-bearing plate 12. A mounting hole (not shown) is provided at the center position of the load-bearing plate 12. The load-bearing plate 12 is further provided with a limiting hole 122 near the material lifting device 50.

[0033] Please refer to Figure 6 The material storage turntable 20 includes six rotating blades 22, a turntable bearing 24, a turntable mounting block 26 and a control device 28, wherein the number of the rotating blades 22 can also be set to other numbers according to specific needs, such as two, three or four, etc. For the convenience of description, the specific embodiment of the present invention is described with six blades. During specific operation, only one of the rotating blades 22 is located in the working position to provide materials for the material conveying device 60 to convey. A central axis hole 21 is further provided at the center of the material storage turntable 20, the turntable mounting block 26 is fixed on the frame bearing plate 12, the turntable bearing 24 is mounted on the turntable mounting block 26, the turntable bearing 24 can simultaneously pass through the mounting hole on the frame bearing plate 12 and the central axis hole 21 of the material storage turntable 20, and then the material storage turntable 20 is mounted on the turntable bearing 24 and is located above the bearing plate 12 at the same time, and the material storage turntable 20 can rotate around the turntable bearing 24.

[0034] Further, each rotating blade 22 includes a rotating body 222, an extension 224, and a connection 225 connecting the rotating body 222 and the extension 224. There is a certain distance between the rotating body 222 and the extension. A positioning groove 226 is formed on the outer side of the connection 225. When the rotating blade 22 is in the working position, the positioning groove 226 corresponds to the limiting hole 122 on the carrier plate 12. The rotating body 222, the extension 224, and the connection 225 are surrounded to form a material accommodating space 228. The middle of the accommodating space is hollowed out for storing the material 2 to be detected. Two material limiting columns 229 are respectively provided on the body 222 and the extension 224, which are used to limit the material 2 stored in the material accommodating space 228 to prevent the material from falling during the conveying process. Of course, the limiting columns 229 can also be set to other numbers, such as setting a limiting column on the rotating body 222 and the extension 224 respectively, and widening the limiting column 229. By setting the height of the material limiting column 229, a number of materials 2 to be detected can be stored on each rotating blade 22. During specific detection, the height of the material limiting column 229 can be adjusted according to actual conditions.

[0035] For the convenience of description, in the following specific description, the rotating blade located at the working position is called the first rotating blade 22, the rotating blade located adjacent to the first rotating blade 22 is called the second rotating blade 22', and the rotating blade located on the other side of the second rotating blade 22' is called the third rotating blade 22".

[0036] Please also read Figures 7 to 9, is a schematic diagram of a turntable power device and a turntable positioning device of a specific embodiment of the present invention. As shown in the figure, the turntable power device 30 and the turntable positioning device 40 are both fixed below the bearing plate 12. Among them, the turntable power device 30 includes a first cylinder 32, a first mounting plate 34, a second mounting plate 36, a turntable power plate 38 and a buffer device 39. The two ends of the first cylinder 32 are respectively fixed on the first mounting plate 34 and the second mounting plate 36. The first mounting plate 34 and the second mounting plate 36 are respectively fixed on the frame body 10. A long strip chute 342 is provided in the center of the first mounting plate 34. The first cylinder 32 further extends toward one end of the first mounting plate 34 to form a telescopic rod 322. The turntable power plate 38 can be locked at the end of the telescopic rod 322 through a bearing structure, and can rotate along the central axis perpendicular to the telescopic rod 322. The turntable power plate 38 is in the shape of a long strip, and its lower half is arranged in the slide groove 342. The slide groove 342 can provide a space for the lower half to move when the turntable power plate 38 rotates, and its upper half can pass through the material storage space 228" of the third rotating blade 22" and protrude from the upper surface of the third rotating blade 22". Of course, the turntable power plate 38 can also be arranged in the material storage space 228 of other rotating blades 22 according to actual needs. For the convenience of explanation, the present invention takes the case where it is located on the third rotating blade 22" as an example. A avoidance groove 382 is arranged in the middle of the turntable power plate 38 corresponding to the position of the telescopic rod 322, which can provide the turntable power plate 38 with an avoidance space when the telescopic rod 322 is extended to avoid collision with the turntable 22. The control device 28 can control the first cylinder 32 to work, so that the telescopic rod 322 shrinks inward or stretches outward. When the telescopic rod 322 shrinks inward, it can drive the turntable power plate 38 to move horizontally and collide with the rotating body 222' of the second rotating blade 22'. When the telescopic rod 322 extends outward, it can drive the turntable power plate 38 to move horizontally. When the turntable power plate 38 moves horizontally, the other side of the upper part collides with the rotating body 222" of the third rotating blade 22". After the back side of the turntable power plate 38 is subjected to force, the lower half of the turntable power plate 38 slides in the slide groove 342 in the first mounting plate 34. Due to the action of the avoidance groove 382, ​​the turntable power plate 38 rotates and tilts forward, forming an angle θ with the first mounting plate 34. The top of the turntable power plate 38 is lower than the bottom surface of the third rotating blade 22". When the bottom of the back side of the turntable power plate 38 collides with the buffer device 39, the turntable power plate 38 will tilt backwards due to the force on the bottom of the back side of the turntable power plate 38. The turntable power plate 38 is in a 90-degree vertical state with the telescopic rod 322, so that the turntable power plate 38 is located in the material accommodating space 228 again.

[0037] The turntable positioning device 40 includes a second cylinder 42, a second cylinder mounting plate 44 and a positioning column 46 disposed on the second cylinder. The second cylinder mounting plates 44 are respectively fixed on both sides of the second cylinder 42 and are simultaneously fixed on the frame body 10. The second cylinder 42 is located at the bottom of the material storage turntable 20. The positioning column 46 includes a positioning body 462 and a telescopic portion 464 disposed on the positioning body 462. The telescopic portion 464 can extend or retract the positioning body 462 under the action of the second cylinder 42. When the control device 28 controls the second cylinder 42 to work and makes the telescopic portion 464 in an extended state, the telescopic portion 464 can pass through the limiting hole 122 on the frame bearing plate 12 and snap into the positioning groove 226 on the first rotating blade 22, thereby fixing the first rotating blade 22 in the working position. When the material 2 in the first rotating blade 22 is taken away, the control device 28 can control the tray power device 30 to collide with the rotating body 222 of the second rotating blade 22' to drive the material storage turntable 22 to rotate counterclockwise, and the telescopic part 464 retracts into the positioning body 462 to provide rotation space for the material storage turntable 20.

[0038] Please combine again Figure 2 , Figure 3 and Fig.10 The material lifting device 50 includes a first slide rail 52, a slide 54 slidingly arranged on the first slide bar 52, a lifting plate 58 fixed at the bottom of the slide 54, a first sensor 56 arranged on the lifting plate 58, and a first driving device 59 arranged at the top of the first slide bar 52. The first slide bar 52 is fixed on the frame body 10. One end of the lifting plate 58 is fixed at the bottom of the slide 54, and the other end extends to the bottom of the material storage space 228 of the first rotating blade 22. The extended part of the structure used for lifting the material is close to the shape of the material to be detected, so as to facilitate lifting the material upward. When the material storage space 228 is filled with material, the lifting plate 58 can hold the material 2 at the bottom. When the first driving device 59 drives the slide 54 to slide up and down along the first slide rail, the slide 54 can drive the lifting plate 58 to move up and down, thereby driving the material 2 to be detected to be lifted upward, so that the top portion of the material 2 to be detected is in the standard material taking position. The first sensor 56 is disposed at the end of the lifting plate 58 and is used to sense whether there is material 2 to be conveyed on the first rotating blade 22 .

[0039] Please combine again Figure 2 , Figure 3 and Fig.11The material conveying device 60 includes a second slide bar 61, a second slide table 62 arranged on the second slide bar 61, a first connecting plate 63 fixed on the second slide table 62, a vacuum generator 66 fixed on the first connecting plate 63, a third cylinder 65 fixed on the first connecting plate 63, a second connecting plate 64 fixed at the bottom of the third cylinder 65, a suction cup 67 fixed at the bottom of the second connecting plate 64, and a second driving device 69 arranged at one end of the second slide rail 61. The second slide bar 61 is fixed on the frame body 10, the second driving device 69 can drive the second slide table 62 to move left and right on the second slide bar 61, the vacuum generator 66 can control the suction cup 67 to suck up or put down the material 2 to be detected, and the third cylinder 65 can control the suction cup to move up and down, so that the suction cup 67 moves upward for a distance after sucking the material 2, so that when the second slide table 62 moves horizontally, the suction cup 67 will not touch the material limiting column 229 on the rotating blade 22. The bottom of the second connecting plate 64 is adjacent to the position of the suction cup 67.

[0040] For ease of understanding, the working process of the automatic feeding device 100 is described in detail below:

[0041] Please also see Figure 2 and Figure 5When a number of materials 2 to be detected are mounted on the first rotating blade 22, the positioning column 46 of the turntable positioning device 40 is located in the positioning groove 226 of the first rotating blade, and the telescopic portion 464 extends out of the surface of the positioning body 462 to fix the first rotating blade 22 in the working position and prevent it from rotating left and right. The upper half of the turntable power plate 38 of the pallet power device 30 is vertically located in the material accommodating space 228 of the third rotating blade 22" and is opposite to the second rotating blade 22', and the lower half of the turntable power plate 38 is located in the slide groove 342 on the first mounting plate 34. The lifting plate 58 of the material lifting device 50 is located at the bottom of the material 2 to be detected, and supports the bottom piece of material 2 to be detected. When working, first, the first sensor 56 on the lifting plate 58 will sense whether there is material on the lifting plate 58. If so, the first driving device 59 drives the first slide 54 to move upward along the first slide rail 52, thereby driving the lifting device 50 to move upward, so that the lifting plate 58 lifts the material 2 upward, and according to the control information of the control device 28, the top piece of material 2 to be detected is located in the standard position; the second sensor 6 8 senses whether there is material 2 at the pick-up and placement position. If it is detected, the vacuum generator 66 drives the suction cup 68 to suck up the material 2, and the third cylinder 65 drives the second connecting plate 64 to move upward, thereby driving the material 2 on the suction cup 68 to move upward a certain distance. The second drive device 69 drives the second slide 62 to move right to transfer the material 2 to the top of the assembly line 400 and place the material on the assembly line 400. The second drive device 69 then drives the second slide 62 to move left back to the material picking position. In the process of the suction cup 67 sucking the material 2 and moving it upward, the first sensor 56 continues to sense whether there is material 2 on the lifting plate 58. If it is detected, the material lifting device 50 and the material conveying device 60 repeat the previous material picking and feeding actions, and so on and so forth until all the material 2 on the first rotating blade 22 is completely transferred.

[0042] Please combine Figure 12-14 When the first sensor 56 detects that there is no material 2 on the lifting plate 58, the control device drives the second cylinder 42 to control the telescopic portion 464 on the positioning column 46 to retract into the positioning body 462 (such as Fig.12), and at the same time, the first cylinder 32 is driven to work, so that the telescopic rod 322 contracts, and the turntable power plate 38 is driven to collide with the rotating body 22 of the second rotating blade 22'. After the rotating body 22 is subjected to force, the material storage turntable 20 rotates counterclockwise under the action of the turntable bearing 24. The control device 28 can control the force of the first cylinder 32 to drive the turntable power plate 38 to collide with the second rotating blade 22', so that the position where the material storage turntable 20 rotates after the force is applied is just the distance of a rotating blade 22, that is: the original second rotating blade 22' is rotated to the position of the original first rotating blade 22. When the second rotating blade 22' rotates to the position of the original first rotating blade 22, the control device 28 controls the second cylinder 42 to work, so that the telescopic part 464 extends out of the positioning body 462, and at the same time, the telescopic part 464 can pass through the limiting hole 122 on the frame bearing plate 12, and be snapped into the positioning groove 226 on the second rotating blade 22', thereby fixing the second rotating blade 22' in the working position.

[0043] Also see Fig.13 and Fig.14 As shown, after the second rotating blade 22' is fixed, the control device 28 controls the first cylinder 32 to work, so that the telescopic rod 322 extends, thereby driving the turntable power plate 38 to extend forward. When the turntable power plate 38 extends, the back of the upper part of the turntable power plate 38 will collide with the rotating body 222" of the third rotating blade 22". After the back of the upper part of the turntable power plate 38 is subjected to force, the lower part of the turntable power plate 38 slides in the slide groove 342 in the first mounting plate 34. Due to the effect of the avoidance groove 382, ​​the turntable power plate 38 rotates and tilts forward. , an angle θ is formed between the first mounting plate 34, and the top of the turntable power plate 38 is lower than the bottom surface of the third rotating blade 22". When the bottom of the back of the turntable power plate 38 collides with the buffer device 39, the turntable power plate 38 will tilt backward due to the force on the bottom of the back of the turntable power plate 38. The turntable power plate 38 is in a 90-degree vertical state with the telescopic rod 322, so that the turntable power plate 38 is located in the material accommodating space 228 again. The material lifting device 50 and the material conveying device 60 repeat the previous working process again, and so on.

[0044] Since each rotating blade 22 is provided with a material limiting column 229, a lot of materials to be tested can be placed on each rotating blade 22, generally about 100 materials can be placed, and six rotating blades 22 can simultaneously place about 600 test materials, which greatly improves the detection efficiency and saves a lot of time. In addition, the tray power device 30 of the present invention does not use any driving motor, but only uses a cylinder to realize the power of the material storage turntable 20 to rotate, which greatly reduces the cost, is simple to operate, and has high detection efficiency.
