Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0018] Please refer to Figures 1-14 , the present application provides a technical solution: a photovoltaic frame intelligent detection device, which comprises a conveying mechanism, a testing mechanism, a material collecting mechanism and a control system. The photovoltaic frame is sent to the testing mechanism through the conveying mechanism, the quality of the photovoltaic frame is divided into high, medium and low grades through the testing mechanism, the detected photovoltaic frame is conveyed to the material collecting mechanism, the material collecting mechanism classifies the photovoltaic frames of the three grades, and the classification is completed.

[0019] The conveying mechanism comprises a folding channel assembly, a discharging assembly, an overturning assembly and a moving-out assembly. The folding channel assembly and the discharging assembly are provided with assemblies and are arranged at intervals, so that the photovoltaic frames on one set of discharging assemblies can be moved to another set of discharging assemblies through the folding channel assembly. The moving-out assembly corresponds to the testing mechanism, and the photovoltaic frames can be moved to the testing mechanism through the moving-out assembly for intelligent detection.

[0020] The folding channel assembly comprises a support frame 28 and two groups of conveying frames 30. The bottom of the support frame 28 is fixed with two groups of push air cylinders 29. The side of the support frame 28 close to the discharging assembly is fixed with two groups of connecting seats 32. The two groups of connecting seats 32 are bearing-connected with rotating shafts 33. The rotating shafts 33 are connected to the two groups of conveying frames 30. The two groups of conveying frames 30 are fixed with connecting frames 31. The output ends of the two groups of push air cylinders 29 are hingedly connected with the connecting frames 31.

[0021] The two groups of conveying frames 30 are provided with conveying belts. The conveying belts are connected through gear transmission. The rotating shafts 33 are in gear transmission connection with the gears on the conveying frames 30. This technology is prior art and will not be described in detail here. One of the two groups of conveying frames 30 is provided with a driving motor. The driving motor is fixedly connected with the rotating shaft 33.

[0022] The discharging assembly comprises a support frame 6, a support table 3 and a mounting seat. The support frame 6 is welded by multiple layers of frames. The support table 3 is bearing-connected with a transmission wheel 4 for supporting the conveying of the cut photovoltaic frame. The support frame 6 is provided with three groups of conveying frames 5. The conveying frames 5 have the same structure as the conveying frames 30 and will not be described in detail here. One end of the three groups of conveying frames 5 is in gear transmission connection with the rotating shaft 33. Therefore, the rotating shaft 33 can drive the conveying frames 30 and the conveying frames 5 to synchronously transmit when the rotating shaft 33 is started.

[0023] The mounting seat is fixed to the support frame 6 and located above the conveying frames 5. The mounting seat is provided with multiple groups. Each group of the mounting seat is fixed with a lifting air cylinder 7. The output end of the lifting air cylinder 7 is fixed with a connecting plate 8. The lower part of the connecting plate 8 is bearing-connected with a connecting shaft 10. The side of the connecting shaft 10 is fixed with a discharging roller 9. The initial state of the discharging roller 9 is flush with the transmission wheel 4, which facilitates the movement of the photovoltaic frame on the transmission wheel 4 to the discharging roller 9.

[0024] The turnover assembly comprises two groups of support frames 13. The top of each group of the support frames 13 is fixed with a mounting plate 14. The bottom of the mounting plate 14 is provided with a motor lead screw drive. The motor lead screw drive is connected with a linear slide rail drive 1. The lower part of the linear slide rail drive 1 is slidingly connected with a linear slide rail drive 2 21. The side of the linear slide rail drive 2 21 is slidingly connected with a Z-shaped plate. The side of the Z-shaped plate is fixed with a turnover motor 17. The other end of the Z-shaped plate is provided with a turnover block 18. The output end of the turnover motor 17 is fixedly connected with the turnover block 18. The outer side of the Z-shaped plate is fixed with a camera 1 19. The top of the support frame 13 is fixed with a camera 2 39. The camera 1 19 and the camera 2 39 are electrically connected with a control system.

[0025] The removal component includes a support frame four, with a linear slide rail drive three 11 fixed to the top of the support frame four. Two sets of placement racks 12 are slidably connected to the top of the linear slide rail drive three 11, and the placement racks 12 have placement slots that are the same size as the photovoltaic frame.

[0026] The cut photovoltaic frame is transported to the discharge assembly by external power. The photovoltaic frame is placed on the transmission wheel 4 and then enters the unloading roller 9. The lifting cylinder 7 is then controlled to lower the photovoltaic frame so that it contacts the three sets of conveyor frames 2 5. Since the conveyor frames 2 5 are always in the starting state, they can be conveyed to the side close to the folding channel assembly. At this time, the conveyor frame 1 30 is pushed by the cylinder 29 to retract. The conveyor frame 1 30 moves away from the conveyor frame 2 5 around the rotating shaft 33. When the photovoltaic frame moves above the conveyor frame 2 5, the cylinder 29 is pushed to extend and control the conveyor frame 1 30 to rotate closer to the conveyor frame 2 5 until the photovoltaic frame contacts the surface of the conveyor frame 2 5. The photovoltaic frame is then moved to the side of the support frame 3 13 by the action of the conveyor frame 2 5.

[0027] It should be noted that the purpose of the cylinder 29 in the folding channel assembly retracting state to drive the first conveyor frame 30 away from the second conveyor frame 5 around one side of the rotation axis 33 is to leave a passage for people to walk through. When people do not pass through, the cylinder 29 is pushed to make the first conveyor frame 30 and the second conveyor frame 5 parallel.

[0028] When the photovoltaic frame approaches one side of the support frame 13, the camera 19 is driven to approach both ends of the photovoltaic frame through the coordination of the motor screw drive, linear slide rail drive one, and linear slide rail drive two 21. The camera captures the cross-section and orientation of the photovoltaic frame, transmitting the signal to the control system and recording the orientation. The uniform orientation of the photovoltaic frame needs to be pre-set in the control system. Then, the motor screw drive, linear slide rail drive one, and linear slide rail drive two 21 are synchronized to bring the flipping block 18 into contact with both ends of the photovoltaic frame, clamping it. The flipping motor 17 is then activated to rotate the flipping block 18, aligning the photovoltaic frame with the orientation set in the control system for subsequent testing. The clamped photovoltaic frame is placed on the placement slot on the placement rack 12, and the two sets of placement racks 12 are moved into the testing mechanism via the linear slide rail drive three 11 for subsequent testing.

[0029] It should be added that the photovoltaic frame of the discharge module on the side near support frame 313 no longer needs to pass through the folding channel module.

[0030] The testing mechanism comprises a lifting assembly and a detection assembly. The lifting assembly comprises a support frame five 15, which has two groups of short beams and one group of long beams. Linear slide rails drive five (not shown in the figure) are arranged on the two groups of short beams. Linear slide rails drive four 38 are slidably connected to the two groups of linear slide rails drive five. A sliding frame 16 is slidably connected to the linear slide rails drive four 38. An installation strip 27 is fixed to the bottom of the sliding frame 16. Finger air cylinders one 26 are fixed to the two ends of the installation strip 27.

[0031] Three groups of conveying frames three 22 are arranged on the side of the support frame five 15 close to the material collecting mechanism. The three groups of conveying frames three 22 are arranged in an upper, middle and lower manner. The structure of the conveying frames three 22 is consistent with that of the conveying frame one 30, and thus will not be described in detail here.

[0032] The detection assembly comprises a support frame six. A bottom plate is fixed to the top of the support frame six. A placement table 23 is fixed to the bottom plate. The placement table 23 is L-shaped and is adapted to the photovoltaic frame. A plurality of grooves one are arranged in the low part of the L-shaped placement table 23. A plurality of grooves two are arranged in the high part of the L-shaped placement table 23. A sensor one 25 is arranged in the grooves one. A sensor two 20 is arranged in the grooves two. The sensor one 25 and the sensor two 20 are electrically connected to the control system.

[0033] It should be noted that the sensor one 25 and the sensor two 20 are laser displacement sensors.

[0034] The material collecting mechanism comprises a three-axis manipulator 1, a robot group 24 and a collecting assembly. The three-axis manipulator 1 comprises an X-axis movement group, a Y-axis movement group and a Z-axis movement group. The Y-axis movement group is arranged in two groups. A clamping assembly is arranged at the end of each Z-axis movement group. The clamping assembly comprises a fixed plate 34. The fixed plate 34 is arranged at the end of the Z-axis movement group. A telescopic air cylinder 37 is fixed to one side of the fixed plate 34. A supporting plate 36 is fixed to the output end of the telescopic air cylinder 37. The supporting plate 36 is located below the fixed plate 34. Slide rods 35 are fixed to the two sides of the fixed plate 34. A connecting sleeve is slidably connected to each group of slide rods 35. The connecting sleeve is fixedly connected to the supporting plate 36. The cooperation of the slide rods 35 and the connecting sleeve ensures the stability of the movement of the supporting plate 36.

[0035] The robot group 24 is arranged on one side of the three-axis manipulator 1 and close to the detection assembly. Finger air cylinders two are arranged at the end of the robot group 24.

[0036] The collecting assembly is arranged below the three-axis manipulator 1 and comprises three groups of collecting frames 2 for collecting photovoltaic frames of different grades.

[0037] When the photovoltaic frame moves under the detection assembly, the cooperation of linear slide drive four 38 and linear slide drive five drives the movement of the sliding frame 16 to move the finger cylinder one 26, moves the photovoltaic frame on the placing rack 12 to the placing table 23, so that the photovoltaic frame contacts with the L-shaped surface of the placing table 23, and the sensor one 25 and the sensor two 20 detect whether the photovoltaic frame is completely in contact with the L-shaped surface of the placing table 23, and transmit the signal to the control system for recording and analyzing the appearance of the photovoltaic frame.

[0038] When the analysis is finished, the photovoltaic frame is divided into high, medium and low three levels by the control system, the detected photovoltaic frame is clamped on the conveying rack three 22 by the finger cylinder two on the robot group 24, because the conveying rack three 22 is provided with three groups, the photovoltaic frames of different levels can be layered, and then the three-axis robot 1 is started to move to one side of the conveying rack three 22, two groups of telescopic cylinders 37 are started at the same time, the two groups of supporting plates 36 are controlled to move close to one side of the photovoltaic frame, the photovoltaic frame is clamped, then the three-axis robot 1 moves to move the clamped photovoltaic frame to the collection frame 2, and the classification and collection of the photovoltaic frame are completed.

[0039] A detection method of a photovoltaic frame intelligent detection device, comprising the following specific operation steps: Step one: through the cooperation of the discharging assembly and the folding channel assembly, the photovoltaic frame is moved to one side close to the moving-out assembly, the photovoltaic frame is turned over to the setting direction by the turnover assembly, and then the photovoltaic frame is moved to the placing rack 12, while clamping the photovoltaic frame, whether the photovoltaic frame will deform is judged; Step two: the two groups of placing racks 12 are moved under the lifting assembly by the linear slide drive three 11, and then the photovoltaic frame is moved to the detection assembly to detect the appearance shape of the photovoltaic frame and judge the quality level of the photovoltaic frame; Step three: the detected photovoltaic frame is classified, the photovoltaic frame is moved to the collection frame 2 by the three-axis robot 1 for classification, and is divided into high, medium and low levels.

[0040] Through the above steps, the problems that in the prior art, each link from conveying, turning over to detection and sorting is often independently operated, the devices are not smoothly connected, the overall detection efficiency is low, and secondary damage is easily caused by multiple handling are overcome, and the work efficiency is improved.

[0041] Step one includes the following specific operation steps: Step one-a: before the turnover assembly works, the camera one 19 first shoots the photo of the end face of the photovoltaic frame and transmits it to the control system to record the direction of the photovoltaic frame at this time; Specifically, the camera one 19 can shoot the end face of the photovoltaic frame and transmit it to the control system to judge whether the end face of the photovoltaic frame is qualified.

[0042] Step one-b: through the control system to calculate the orientation of the photovoltaic frame, facilitate the flip assembly to rotate the photovoltaic frame to the set orientation, and then clamp the photovoltaic frame; Specifically, since the orientation is set in the control system, the photo of the end face of the photovoltaic frame taken in real time is compared with the set image, and the angle at which the flip motor 17 needs to be flipped is calculated. When the flip block 18 clamps the end face of the photovoltaic frame, the flip motor 17 flips the photovoltaic frame according to the angle calculated by the control system, so that it is consistent with the set photo, and then the photovoltaic frame is placed on the placing rack 12.

[0043] It should be noted that the calculated angle of the flip motor 17 is a formula set in the control system, which will not be described in detail here.

[0044] It should be noted that the flip assembly clamps the photovoltaic frame, and the camera two 39 takes a photo of the photovoltaic frame before clamping and transmits it to the control system as a comparison reference photo.

[0045] Step one-c: when the clamped photovoltaic frame is clamped, further squeeze the photovoltaic frame to make it deform.

[0046] Specifically, the flip block 18 at both ends of the photovoltaic frame further clamps the photovoltaic frame, and then can squeeze the photovoltaic frame to make it deform, and then place the photovoltaic frame on the placing rack 12 to make it stand for a period of time. At this time, the photo of the photovoltaic frame taken by the camera two 39 is transmitted to the control system for comparison with the reference photo. If the comparison is consistent, it means that the photovoltaic frame has not deformed after springback. If the comparison is inconsistent, mark this photovoltaic frame in the control system.

[0047] Step two includes the following specific operation steps: Step two-a: when the linear slide rail drive three 11 moves the placing rack 12 under the lifting assembly, clamp the photovoltaic frame on the placing rack 12 to the placing table 23.

[0048] Step two-b: detect the straightness of the appearance of the photovoltaic frame through the sensor one 25 and the sensor two 20 on the placing table 23.

[0049] Specifically, when the photovoltaic frame contacts the L-shaped surface on the placing table 23, the surface of the photovoltaic frame contacts the sensor one 25 and the sensor two 20. If each group of sensor one 25 and sensor two 20 contacts the photovoltaic frame, it means that the straightness of the photovoltaic frame is high. When multiple groups of sensor one 25 or sensor two 20 do not contact, it means that the straightness of the photovoltaic frame is medium. When multiple groups of sensor one 25 and sensor two 20 do not contact at the same time, it means that the straightness of the photovoltaic frame is low.

[0050] When the straightness of the photovoltaic frame is intermediate and low, and the photovoltaic frame is marked, it indicates that the photovoltaic frame is deformed during the extrusion in the previous process, indicating that the quality of the photovoltaic frame is intermediate; when the straightness of the photovoltaic frame is high, and the photovoltaic frame is marked, it indicates that the photovoltaic frame restores the shape after extrusion, indicating that the quality of the photovoltaic frame is high; when the straightness of the photovoltaic frame is intermediate and low, and the photovoltaic frame is not marked, it indicates that the photovoltaic frame itself has quality defects, not defects caused by extrusion, and the quality of the photovoltaic frame is low.

[0051] Step two-c: when the quality of the photovoltaic frame is intermediate, further analyze the profile defect distribution of the photovoltaic frame.

[0052] When the straightness of the photovoltaic frame is intermediate and low, the straightness distribution can be further analyzed, when a plurality of sensors (including sensor one 25 and sensor two 20) do not detect contact with the photovoltaic frame, it indicates that the photovoltaic frame is linearly deformed when it is extruded, and a slope (as shown in Figure 13 ) is generated; when there is a gap between the sensors that do not contact the surface of the photovoltaic frame, it indicates that the photovoltaic frame is irregularly deformed (as shown in Figure 14 ) when it is extruded, the deformation of the photovoltaic frame can be further analyzed to facilitate subsequent workers to understand the specific quality of the photovoltaic frame.

[0053] Through the above steps, the quality of the photovoltaic frame is intelligently detected, and the overall process of transportation-detection-collection replaces the manual operation in the prior art, thereby improving work efficiency and saving labor cost.
