Description

Technical Field

[0001] This invention relates to the field of photovoltaic frame detection technology, specifically to a photovoltaic frame intelligent detection device and its detection method. Background Technology

[0002] As a crucial component of photovoltaic (PV) modules, the quality of the frame directly impacts the structural strength, sealing performance, and lifespan of the PV module. During the PV frame manufacturing process, due to factors such as material properties and processing techniques, the frame may exhibit appearance defects such as bending, twisting, and localized deformation, as well as latent deformation caused by insufficient compression or springback. If these defects are not detected in a timely manner, they will lead to difficulties in subsequent assembly, degraded module performance, and even premature failure.

[0003] Currently, the quality inspection of photovoltaic frames mainly relies on manual visual inspection or measurement with simple tools, which suffers from low efficiency, high labor intensity, strong subjectivity, and poor consistency. Although some automated inspection equipment has been put into use, the following shortcomings still exist: poor process coordination: each link from conveying and flipping to inspection and sorting often operates independently, and the connection between equipment is not smooth, resulting in low overall inspection efficiency and easy secondary damage due to repeated handling. This phenomenon has become a problem that urgently needs to be solved by people in this field. Summary of the Invention

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] Please see Figure 1-14 The present invention provides a technical solution: a photovoltaic frame intelligent inspection device, including a conveying mechanism, a testing mechanism, a receiving mechanism and a control system. The photovoltaic frame is sent to the testing mechanism by the conveying mechanism, and the quality of the photovoltaic frame is divided into three levels: high, medium and low by the testing mechanism. The inspected photovoltaic frame is then sent to the receiving mechanism, which classifies the photovoltaic frames into high, medium and low levels to complete the classification.

[0050] The conveying mechanism includes a folding channel assembly, a discharge assembly, a flipping assembly, and a removal assembly. The folding channel assembly and the discharge assembly are equipped with components that are spaced apart from each other, so that the photovoltaic frame on one set of discharge assemblies can be moved to another set of discharge assemblies through the folding channel assembly. The removal assembly corresponds to the testing mechanism, and the photovoltaic frame can be moved into the testing mechanism for intelligent detection.

[0051] The folding channel assembly includes a support frame 28 and two sets of conveyor frames 30. Two sets of push cylinders 29 are fixed at the bottom of the support frame 28. A connecting seat 32 is fixed on the side of the support frame 28 near the discharge assembly. There are two sets of connecting seats 32. A rotating shaft 33 is connected to the two sets of conveyor frames 30 by bearings. The rotating shaft 33 is connected to the two sets of conveyor frames 30. A connecting frame 31 is fixed on the two sets of conveyor frames 30. The output ends of the two sets of push cylinders 29 are hinged to the connecting frame 31.

[0052] Both sets of conveyor frames 30 are equipped with conveyor belts, which are connected by gear transmission. The rotating shaft 33 is also connected to the gear transmission on the conveyor frame 30. This technology is existing technology and will not be described in detail here. One set of conveyor frames 30 is equipped with a drive motor, which is fixedly connected to the rotating shaft 33.

[0053] The material discharge assembly includes a second support frame 6, a support platform 3, and a mounting base. The second support frame 6 is made of a multi-layer frame welded together. The support platform 3 has a transmission wheel 4 connected to the bearing to support and transport the cut photovoltaic frame. The second support frame 6 is equipped with three sets of second conveyor frames 5. The structure of the second conveyor frames 5 is the same as that of the first conveyor frame 30, which will not be described in detail here. One end of each of the three sets of second conveyor frames 5 is connected to the rotating shaft 33 through gear transmission. Therefore, when the rotating shaft 33 is started, it can simultaneously drive the first conveyor frame 30 and the second conveyor frame 5 to drive synchronously.

[0054] The mounting base is fixed on the support frame 2 6 and located above the conveyor frame 2 5. Multiple sets of mounting bases are provided, each set with a lifting cylinder 7 fixed on it. A connecting plate 8 is fixed to the output end of the lifting cylinder 7. A connecting shaft 10 is connected to the lower bearing of the connecting plate 8, and a feeding roller 9 is fixed to one side of the connecting shaft 10. The feeding roller 9 is initially flush with the transmission wheel 4, facilitating the movement of the photovoltaic frame on the transmission wheel 4 onto the feeding roller 9.

[0055] The flipping assembly includes two sets of support frames 13. Mounting plates 14 are fixed to the top of each set of support frames 13. A motor screw drive is installed at the bottom of the mounting plate 14. A linear slide rail drive is connected to the motor screw drive. A linear slide rail drive 21 is slidably connected below the linear slide rail drive 1. A U-shaped plate is slidably connected to one side of the linear slide rail drive 21. A flipping motor 17 is fixed to one side of the U-shaped plate. A flipping block 18 is installed at the other end of the U-shaped plate. The output end of the flipping motor 17 is fixedly connected to the flipping block 18. A camera 19 is fixed to the outside of the U-shaped plate. A camera 29 is fixed to the top of the support frame 13. Cameras 19 and 29 are electrically connected to the control system.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] The testing mechanism includes a lifting component and a detection component. The lifting component includes a support frame 15, which has two sets of short beams and one set of long beams. Linear slide rail drives (not shown in the figure) are installed on the two sets of short beams. Linear slide rail drives 38 are slidably connected to the two sets of linear slide rail drives. A sliding frame 16 is slidably connected to the linear slide rail drives 38. An installation strip 27 is fixed to the bottom of the sliding frame 16. Finger cylinders 26 are fixed to both ends of the installation strip 27.

[0062] Three sets of conveyor frames 22 are provided on the side of the support frame 515 near the receiving mechanism. The three sets of conveyor frames 22 are arranged at the top, middle and bottom. The structure of the conveyor frames 22 is the same as that of the conveyor frame 30, so it will not be described in detail here.

[0063] The detection component includes a support frame six, with a base plate fixed to the top of the support frame six. A placement platform 23 is fixed to the base plate. The placement platform 23 is L-shaped and adapted to the photovoltaic frame. Several grooves 1 are formed at the lower part of the L-shape of the placement platform 23, and several grooves 2 are formed at the higher part of the L-shape of the placement platform 23. Sensor 1 25 is placed inside the groove 1, and sensor 2 20 is placed inside the groove 2. Sensor 1 25 and sensor 2 20 are electrically connected to the control system.

[0064] It should be added that sensor 25 and sensor 20 are laser displacement sensors.

[0065] The material receiving mechanism includes a three-axis manipulator 1, a robot group 24, and a collection component. The three-axis manipulator 1 consists of an X-axis motion group, a Y-axis motion group, and a Z-axis motion group. There are two Y-axis motion groups. Each Z-axis motion group has a clamping component at its end. The clamping component includes a fixed plate 34, which is located at the end of the Z-axis motion group. A telescopic cylinder 37 is fixed to one side of the fixed plate 34. A support plate 36 is fixed to the output end of the telescopic cylinder 37. The support plate 36 is located below the fixed plate 34. Slide rods 35 are fixed to both sides of the fixed plate 34. A connecting sleeve is slidably connected to each slide rod 35. The connecting sleeve is fixedly connected to the support plate 36. The stability of the movement of the support plate 36 is ensured by the cooperation of the slide rods 35 and the connecting sleeve.

[0066] Robot group 24 is located on one side of the three-axis manipulator 1 and close to the detection component. The end of robot group 24 is equipped with finger cylinder 2.

[0067] The collection component is located below the three-axis robot 1 and includes three collection boxes 2, which collect photovoltaic frames of different grades respectively.

[0068] When the photovoltaic frame moves below the detection component, the movement of the sliding frame 16 is controlled by the cooperation of linear slide rail drive 4 38 and linear slide rail drive 5, which drives the finger cylinder 1 26 to move, moving the photovoltaic frame on the placement frame 12 onto the placement platform 23, so that the photovoltaic frame contacts the L-shaped surface of the placement platform 23. The sensors 1 25 and 2 20 detect whether the photovoltaic frame is in complete contact with the L-shaped surface of the placement platform 23, and transmit the signal to the control system for recording and analysis of the appearance of the photovoltaic frame.

[0069] After the analysis is completed, the photovoltaic frames are divided into three levels: high, medium and low by the control system. The detected photovoltaic frames are clamped onto the conveyor frame 22 by the finger cylinder 2 on the robot group 24. Since the conveyor frame 22 is set with three sets, the photovoltaic frames of different levels can be set in layers. Then, the three-axis robot arm 1 is started and moved to one side of the conveyor frame 22. The two sets of telescopic cylinders 37 are started at the same time, controlling the two sets of trays 36 to move closer to the photovoltaic frames and clamp them. Then, the clamped photovoltaic frames are moved into the collection box 2 by the movement of the three-axis robot arm 1, completing the classification and collection of photovoltaic frames.

[0070] A detection method for a photovoltaic frame intelligent detection device includes the following specific operation steps:

[0071] Step 1: By cooperating with the discharge component and the folding channel component, move the photovoltaic frame to the side closer to the discharge component, flip the photovoltaic frame to the set orientation by the flipping component, and then move the photovoltaic frame to the placement rack 12. While holding the photovoltaic frame, determine whether the photovoltaic frame will deform.

[0072] Step 2: Move the two sets of placement racks 12 to below the lifting component using the linear guide drive 311, then move the photovoltaic frame onto the detection component to detect the appearance and shape of the photovoltaic frame and determine the quality level of the photovoltaic frame;

[0073] Step 3: Classify the inspected photovoltaic frames. The three-axis robot 1 moves the photovoltaic frames to the collection box 2 for classification into high, medium and low grades.

[0074] The above steps overcome the problems in existing technologies where each link from conveying and flipping to detection and sorting often operates independently, with poor connection between equipment, resulting in low overall detection efficiency and easy secondary damage due to repeated handling, thus improving work efficiency.

[0075] Step one includes the following specific steps:

[0076] Step 1-a: Before the flipping module starts working, take a picture of the end face of the photovoltaic frame through camera 19 and transmit it to the control system to record the orientation of the photovoltaic frame at this time;

[0077] Specifically, camera 19 can capture images of the photovoltaic frame's end face and transmit them to the control system to determine whether the photovoltaic frame's end face is qualified.

[0078] Step 1-b: The control system calculates the orientation of the photovoltaic frame to facilitate the rotation of the photovoltaic frame to the set orientation when flipping the module, and then clamps the photovoltaic frame;

[0079] Specifically, since the orientation is set in the control system, the real-time captured photo of the photovoltaic frame end face is compared with the set image to calculate the angle that the flip motor 17 needs to flip. 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 placement rack 12.

[0080] It should be noted that the calculated angle of the flip motor 17 is based on a formula set in the control system, which will not be elaborated on here.

[0081] It should be added that the camera 239 takes a picture of the photovoltaic frame before it is clamped by the flip component and transmits it to the control system as a comparison reference picture.

[0082] Step 1-c: Once the photovoltaic frame is properly clamped, further squeeze the photovoltaic frame to deform it.

[0083] Specifically, the flipping blocks 18 at both ends of the photovoltaic frame further clamp the photovoltaic frame, which can then squeeze the photovoltaic frame to deform it. The photovoltaic frame is then placed on the placement rack 12 and left to stand for a period of time. At this time, the photovoltaic frame is photographed by the camera 39 and 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 during the rebound. If the comparison is inconsistent, the photovoltaic frame is marked in the control system.

[0084] Step two includes the following specific operational steps:

[0085] Step 2-a: When the linear slide rail drive 3 11 moves the placement frame 12 below the lifting component, the photovoltaic frame on the placement frame 12 is then clamped onto the placement platform 23.

[0086] Step 2-b: Detect the straightness of the photovoltaic frame appearance using sensor 25 and sensor 20 on the placement platform 23.

[0087] Specifically, when the photovoltaic frame contacts the L-shaped surface on the placement platform 23, the surface of the photovoltaic frame contacts sensor 1 25 and sensor 2 20. If each set of sensor 1 25 and sensor 2 20 contacts the photovoltaic frame, it indicates that the straightness of the photovoltaic frame is high. When multiple sets of sensor 1 25 or sensor 2 20 do not contact, it indicates that the straightness of the photovoltaic frame is medium. When multiple sets of sensor 1 25 and sensor 2 20 do not contact at the same time, it indicates that the straightness of the photovoltaic frame is low.

[0088] When the straightness of the photovoltaic frame is rated as medium or low, and it is a marked photovoltaic frame, it indicates that the photovoltaic frame was deformed during the extrusion process in the previous step, indicating that the quality of the photovoltaic frame is medium. When the straightness of the photovoltaic frame is rated as high, and it is a marked photovoltaic frame, it indicates that the photovoltaic frame recovered its shape after extrusion, indicating that the quality of the photovoltaic frame is high. When the straightness of the photovoltaic frame is rated as medium or low, and it is an unmarked photovoltaic frame, it indicates that the photovoltaic frame itself has quality defects, which are not caused by extrusion, and the quality of the photovoltaic frame is low.

[0089] Step 2-c: When the quality of the photovoltaic frame is set to medium, further analyze the distribution of shape defects in the photovoltaic frame.

[0090] When the straightness of the photovoltaic frame is at a medium or low level, the straightness distribution can be further analyzed. When several consecutive sensors (including sensor 25 and sensor 20) fail to detect contact with the photovoltaic frame, it indicates that the photovoltaic frame undergoes linear deformation under pressure, resulting in a sloping surface (such as...). Figure 13 As shown), when there are gaps between the sensors that are not in contact with the photovoltaic frame surface, it indicates that the photovoltaic frame undergoes irregular deformation when squeezed (e.g., Figure 14 As shown in the figure, the deformation of the photovoltaic frame can be further analyzed, which will help subsequent staff to understand the specific quality of the photovoltaic frame.

[0091] By implementing the above steps, the quality inspection of photovoltaic frames will be made intelligent, replacing manual operations in the existing technology with the entire process of transportation, inspection and collection, thereby improving work efficiency and saving labor costs.
