Description

Technical Field

[0001] This application relates to the field of photovoltaic frame processing technology, and in particular to an automatic detection device for photovoltaic frame processing. Background Technology

[0002] The amount of electricity output by a photovoltaic (PV) module is directly proportional to the amount of sunlight it absorbs. PV modules are mounted on a frame using a PV frame to ensure they absorb the maximum amount of sunlight and achieve maximum conversion efficiency. The material of the PV frame itself must be oxidation-resistant and corrosion-resistant, and, more importantly, able to withstand the loads of various natural environments such as wind, snow, and hail. Therefore, after the PV frame is manufactured, its length, width, cutting angle, and the location of the mounting holes need to be inspected.

[0003] Because photovoltaic frames require testing for multiple data points, and currently all photovoltaic frame testing is done manually, the workload is large, time-consuming, and inefficient. Summary of the Invention

[0004] To address the aforementioned issues, this application provides an automatic inspection device for photovoltaic frame processing.

[0005] The automatic detection device for photovoltaic frame processing provided in this application adopts the following technical solution:

[0006] An automatic inspection device for photovoltaic frame processing includes a worktable. The worktable is equipped with a feeding component, a first inspection component, a second inspection component, a hole position inspection component, and a pushing component. The feeding component includes a feeding belt that is wound around the worktable and is used to carry the workpiece. The first inspection component is used to detect the length and cutting angle of the workpiece. The second inspection component is used to detect the width and curvature of the workpiece. The hole position inspection component is used to detect the opening position of the mounting holes on the workpiece. The pushing component includes a pushing block that is used to push the workpiece to separate it from the feeding belt.

[0007] By adopting the above technical solution, the workpiece is placed on the feeding belt, which carries the workpiece to the first detection component to detect the length and cutting angle of the workpiece. If it is unqualified, the pusher block pushes the workpiece to separate it from the feeding belt for recycling. If it is qualified, the feeding belt continues to move. The second detection component and the hole position detection component work in the same way. After the detection is completed, if all the data of the workpiece are qualified, the detection is completed. This realizes the automation of the workpiece detection process and allows unqualified workpieces to be recycled in time, improving detection efficiency and detection accuracy.

[0008] Preferably, the feeding assembly further includes a feeding motor and several feeding shafts and feeding wheels. The feeding motor is fixedly connected to the worktable, the feeding shafts are rotatably connected to the worktable, the feeding motor drives the feeding shafts to rotate, the feeding wheels are coaxially fixed on the feeding shafts, and the feeding belt is wound around the feeding wheels.

[0009] By adopting the above technical solution, the feeding motor is preset by the PLC program, the feeding motor drives the feeding shaft to rotate, and the feeding shaft drives the feeding belt to move, so that the workpiece placed on the feeding belt can be moved to the corresponding inspection position according to the inspection needs.

[0010] Preferably, the first detection component includes a placement block, a first moving block, and a second moving block. The placement block moves up and down relative to the worktable. The first moving block and the second moving block are respectively located at opposite ends of the placement block. The first moving block and the second moving block move towards or away from each other synchronously. An angle detection block is provided on both the first moving block and the second moving block. The surface of the angle detection block closest to the workpiece is the detection surface. The detection surface is inclined at 45° and abuts against the end face of the workpiece.

[0011] By adopting the above technical solution, when the first detection component detects the workpiece, the first moving block and the second moving block move closer to each other until the detection surface of the angle detection block is completely against the end face of the workpiece. At this time, it can be determined whether the end face cutting angle of the workpiece is qualified.

[0012] Preferably, the first detection component further includes a driving component, which includes a drive motor and a double-threaded screw. The double-threaded screw is fixedly connected to the output shaft of the drive motor. The placement block has a moving groove, and the first moving block and the second moving block are threadedly connected to the double-threaded screw and located in the moving groove.

[0013] By adopting the above technical solution, when the workpiece moves to the corresponding inspection position, the drive motor starts to drive the double threaded screw to rotate. Since the first moving block and the second moving block are both threadedly connected to the double threaded screw, the first moving block and the second moving block move synchronously along the moving groove and abut against the workpiece, reducing the manual operation of the centering steps and improving the automation level of the inspection process.

[0014] Preferably, the first moving block and the second moving block are provided with a first pressure sensor and a first distance sensor. The first pressure sensor is located inside the angle detection block, and the first distance sensor is located on the first moving block. The first pressure sensor and the first distance sensor are electrically connected. The first pressure sensor transmits a signal to the first distance sensor. The first distance sensor is used to measure the distance between the first moving block and the second moving block.

[0015] By adopting the above technical solution, when the detection surface abuts against the end face of the workpiece, the first pressure sensor detects pressure and can determine that the cutting angles on both sides meet the requirements. Then, the first pressure sensor transmits a signal to the first distance sensor. The first distance sensor measures whether the distance between the two moving blocks is consistent with the preset value, and then determines whether the length of the workpiece is qualified. If it is qualified, the feeding belt can carry the workpiece to continue moving to the next detection position. Otherwise, the pusher block is activated to separate the workpiece from the feeding belt, thereby improving the detection efficiency.

[0016] Preferably, the second detection component includes a first clamping block and a second clamping block, which are slidably connected to the worktable. The first clamping block and the second clamping block are centrally symmetrically arranged. The first clamping block includes an abutment plate that abuts against the workpiece. The abutment plate is provided with a plurality of curvature detectors for detecting the curvature of the workpiece.

[0017] By adopting the above technical solution, the workpiece rotates and moves with the feeding belt, and stops at the second detection component. The first clamping block and the second clamping block move relative to the worktable and move closer to each other, so that the abutment plate abuts against one side of the workpiece. The abutment plate is equipped with multiple curvature detectors. If all the multiple curvature detectors can detect the workpiece, the workpiece is qualified; otherwise, it is unqualified.

[0018] Preferably, both the first clamping block and the second clamping block include clamping plates. The two clamping plates abut against opposite sides of the workpiece in the width direction and clamp the workpiece. A second distance sensor is provided on the clamping plate. The curvature detector is electrically connected to the second distance sensor. The curvature detector transmits a signal to the second distance sensor. The second distance sensor is used to detect the distance between the two clamping plates. The second distance sensor is electrically connected to the feeding motor and transmits a signal to the feeding motor.

[0019] By adopting the above technical solution, the first clamping block and the second clamping block move, so that the two clamping plates clamp the workpiece in the width direction. When the curvature detector detects the workpiece, the curvature of the workpiece is qualified. Then the curvature detector sends a signal to the second distance detector. The second distance detector detects whether the distance between the two clamping plates is consistent with the preset value and determines whether the width dimension of the workpiece is qualified. If it is qualified, the second distance detector transmits a signal to the feeding motor. The feeding motor drives the feeding belt to continue moving for the next dimension detection. Otherwise, the pusher block is activated to separate the workpiece from the feeding belt and recover it in time, reducing wasted time and improving operating efficiency.

[0020] Preferably, the hole position detection assembly includes a connecting frame and at least two laser detectors. The connecting frame is fixedly connected to the worktable and located above the workpiece. A connecting plate is slidably connected to the connecting frame. At least two laser detectors are fixedly connected to the connecting plate. At least two receiving blocks are provided on the worktable and below the workpiece. The spacing between two adjacent receiving blocks is the same as the spacing between two adjacent laser detectors. The receiving blocks are used to receive laser detector signals.

[0021] By adopting the above technical solution, the feeding belt carries the workpiece to the next detection position, and the connecting plate carries the laser detector. When at least two receiving blocks can receive the laser signal from the laser detector synchronously, it can be determined that the hole position on the workpiece is accurate; if the receiving blocks cannot receive the laser signal synchronously, it is determined that the hole position on the workpiece is deviated, and the workpiece is unqualified.

[0022] Preferably, the pushing assembly further includes a pushing platform and a pushing cylinder. The pushing cylinder is fixedly connected to the pushing platform, and the pushing block is fixedly connected to the piston rod of the pushing cylinder. A single pushing cylinder and a single pushing block form a group.

[0023] By adopting the above technical solution, if a defective workpiece is found during the process of moving and inspecting the workpiece on the workbench, the pusher cylinder is activated to drive the pusher block to move, so that the workpiece is separated from the feed belt in time and enters the recycling vehicle for centralized recycling of defective workpieces, which can also improve the inspection efficiency of workpieces.

[0024] Preferably, it also includes a recycling vehicle, which is detachably connected to the workbench and located below the first detection component, the second detection component and the hole position detection component.

[0025] By adopting the above technical solution, no matter which step the workpiece inspection is at, as long as unqualified inspection data is obtained, the pusher block can promptly push the workpiece away from the feeding belt and into the recycling vehicle for centralized recycling and processing.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. By setting up a feeding assembly, a first detection assembly, a second detection assembly, and a hole position detection assembly, the workpiece is placed on the feeding belt. The feeding belt carries the workpiece to the first detection assembly, where the length and cutting angle of the workpiece are detected. If it is unqualified, a pusher block pushes the workpiece to separate it from the feeding belt for recycling. If it is qualified, the feeding belt continues to move. The second detection assembly and the hole position detection assembly work similarly. After the detection is completed, if all the data of the workpiece are qualified, the detection is completed. This automates the workpiece detection process and allows unqualified workpieces to be recycled in a timely manner, improving both detection efficiency and accuracy.

[0028] 2. By setting the curvature detector and the second distance sensor, the first clamping block and the second clamping block move, so that the two clamping plates clamp the workpiece in the width direction. When the curvature detector detects the workpiece, the curvature of the workpiece is qualified. Then the curvature detector sends a signal to the second distance detector. The second distance detector detects whether the distance between the two clamping plates is consistent with the preset value and determines whether the width dimension of the workpiece is qualified. If it is qualified, the second distance detector transmits a signal to the feeding motor. The feeding motor drives the feeding belt to continue moving for the next dimension detection. Otherwise, the pusher block is activated to separate the workpiece from the feeding belt and recover it in time, reducing wasted time and improving operating efficiency. Attached Figure Description

Detailed Implementation

[0037] The following is combined with Figure 1-7 This application will be described in further detail.

[0038] This application discloses an automatic detection device for photovoltaic frame processing, such as... Figure 1 and 2 As shown, the workbench 1 is provided with a first detection component 4, a second detection component 5 and a hole position detection component 6. The first detection component 4 is used to detect the length and end face cutting angle of the workpiece 8, the second detection component 5 is used to detect the width and curvature of the workpiece 8, and the hole position detection component 6 is used to detect the opening position of the mounting hole 83 on the workpiece 8.

[0039] like Figure 1 As shown, it also includes a feeding assembly 2, which includes a feeding motor (not shown in the figure), a feeding belt 22 and multiple feeding shafts 21. The feeding motor is fixedly connected to the worktable 1, and the multiple feeding shafts 21 are rotatably connected to the worktable 1. A feeding wheel 211 is coaxially fixed on the feeding shaft 21, and the feeding belt 22 is wound around the feeding wheel 211. The feeding motor drives the feeding shaft 21 to rotate and drives the feeding belt 22 to move. The worktable 1 is provided with three detection areas. The feeding belt 22 carries the workpiece 8 to move and detects the workpiece 8 one by one.

[0040] like Figure 1As shown, it also includes a pushing assembly 3, which includes a pushing platform 31, a pushing cylinder 32, and a pushing block 33. The pushing platform 31 is located on one side of the worktable 1. The pushing cylinder 32 is fixedly connected to the pushing platform 31, and the pushing block 33 is fixedly connected to the piston rod of the pushing cylinder 32. The piston rod of the pushing cylinder 32 drives the pushing block 33 to move towards the worktable 1. One pushing cylinder 32 and one pushing block 33 form a group. In this embodiment, there are three groups, which correspond one-to-one with the three detection areas.

[0041] like Figure 3 As shown, it also includes a recycling cart 7, which is placed on the workbench 1 and located directly below the three inspection areas to facilitate the recycling of defective workpieces 8.

[0042] like Figure 1 and 3 As shown, the first detection component 4 is located in the first detection area. The first detection component 4 includes a placement block 41, a driving component 42, a first moving block 43, and a second moving block 44. A moving hole 11 is provided on the worktable 1. A sliding plate 111 is slidably connected inside the wall of the moving hole 11. The other side of the sliding plate 111 is fixedly connected to the placement block 41. The driving component 42 includes a driving motor 421 and a double-threaded screw 422. The driving motor 421 is fixedly connected to one side of the placement block 41. A moving groove 411 is provided on the placement block 41. One end of the double-threaded screw 422 is fixedly connected to the output shaft of the driving motor 421, and the other end passes through the placement block 41 and is fixedly connected to a limit plate. The first moving block 43 and the second moving block 44 are located in the moving groove 411, and both are threadedly connected to the double-threaded screw 422. Angle detection blocks 431 are fixedly connected to both the first moving block 43 and the second moving block 44. The surfaces of the angle detection blocks 431 that are close to each other are detection surfaces, and the detection surfaces are inclined at 45°. A first pressure sensor is fixedly connected to each angle detection block 431, and a first distance sensor 432 is fixedly connected to each of the first moving block 43 and the second moving block 44. The first pressure sensor is electrically connected to the first distance sensor 432, and the first distance sensor 432 is electrically connected to the sliding plate 111 and the pusher cylinder 32 corresponding to the first detection area.

[0043] like Figure 1 , 2As shown in Figure 3, workpiece 8 includes a first plate surface 81 and a second plate surface 82. Workpiece 8 is placed on the feeding belt 22, with the first plate surface 81 adhering to the feeding belt 22. Workpiece 8 moves with the feeding belt 22 to the first detection area. The drive motor 421 starts, driving the double-threaded screw 422 to rotate, causing the first moving block 43 and the second moving block 44 to move closer to each other. The detection surface of the angle detection block 431 completely abuts against both ends of workpiece 8. At this time, if the first pressure sensor does not detect pressure or only one can detect pressure, the cutting angle of the end face of workpiece 8 is unqualified; if all the first pressure sensors on the angle detection block 431 detect pressure, the cutting angle of the end face of workpiece 8 is qualified. Then, the first pressure sensor sends a signal to the first distance sensor 432. After receiving the signal, the first distance sensor 432 starts and measures the distance between the first moving block 43 and the second moving block 44. If the measured value is consistent with the preset length value in the PLC program, the length of workpiece 8 is qualified; the first moving block 43 and the second moving block 44 reset, and the feeding motor continues to run. If the measured value of the first distance sensor 432 is inconsistent with the preset length value, it is determined that the length of the workpiece 8 is unqualified. At this time, the first distance sensor 432 sends a signal to the sliding plate 111, and the sliding plate 111 drives the placement block 41, the first moving block 43 and the second moving block 44 to move downward along the worktable 1. At the same time, the corresponding pusher cylinder 32 receives the signal and starts, driving the pusher block 33 to move closer to the workpiece 8 and push the workpiece 8 away from the feeding belt 22, so that the unqualified workpiece 8 can enter the recycling vehicle 7 in time.

[0044] like Figure 1 and 4As shown, it also includes an actuating assembly 9, which includes an abutment wheel 91, a rotating rod 911, a drive wheel 912, a transmission wheel 92, and an actuating rod 921. The rotating rod 911 is rotatably connected to the worktable 1. The abutment wheel 91 is coaxially and fixedly connected to the end of the rotating rod 91 away from the worktable 1, and the wheel surface of the abutment wheel 91 abuts against the feeding belt 22. The drive wheel 912 is coaxially and fixedly fixed to the rotating rod 911. A fixed plate 93 is fixedly connected to the worktable 1. The actuating rod 921 passes through the fixed plate 93 and rotates relative to the fixed plate 93, and the length direction of the actuating rod 921 is perpendicular to the length direction of the rotating rod 911. The transmission wheel 92 is coaxially and fixedly connected to one end of the actuating rod 921, and the transmission wheel 92 meshes with the drive wheel 912. An actuating plate 922 is fixedly connected to the end of the actuating rod 921 away from the transmission wheel 92. After the length and cutting precision of workpiece 8 pass the inspection, the feeding motor continues to run, driving the feeding belt 22 to move. The feeding belt 22 drives the abutment wheel 91 to rotate, which in turn drives the rotating rod 911 and the drive wheel 912 to rotate synchronously. The drive wheel 912 drives the transmission wheel 92 and the actuating rod 921 to rotate, and the actuating rod 921 drives the actuating plate 922 to rotate. According to the distance preset in the PLC program, the feeding belt 22 moves from the first inspection area to the abutment wheel 91. The actuating plate 922 actuates the second plate surface 82 of workpiece 8, so that the second plate surface 82 is placed in contact with the feeding belt 22.

[0045] like Figure 3 and 5 As shown, the second detection component 5 is located in the second detection area. The second detection component 5 includes a first clamping block 51 and a second clamping block 52. The first clamping block 51 includes a sliding rod 511, an abutment plate 512, and a clamping plate 513. Sliding grooves 12 are provided on both inner walls of the worktable 1. The bottom of the sliding grooves 12 is arc-shaped, and the openings of the two sliding grooves 12 are opposite to each other. One end of the sliding rod 511 extends into the sliding groove 12 and moves along the sliding groove 12, while the other end is fixedly connected to the abutment plate 512. The clamping plate 513 is fixedly connected to one side of the abutment plate 512, and the surfaces of the abutment plate 512 and the clamping plate 513 are perpendicular to each other. Two curvature detectors 5121 are fixedly connected to each individual abutment plate 512, and a second distance sensor 5131 is fixedly connected to the clamping plate 513. A receiving plate 13 is movably connected inside the sliding trough 12. The receiving plate 13 moves along the depth of the trough. The second distance sensor 5131 is electrically connected to the receiving plate 13. A second pressure sensor 121 is provided at one end of the sliding trough 12 near the recycling vehicle 7. The second pressure sensor 121 is electrically connected to the receiving plate 13 and the corresponding pushing cylinder 32.

[0046] The second plate surface 82 of workpiece 8 is placed against the feeding belt 22 and continues to move. When it moves to the second detection area, the first clamping block 51 and the second clamping block 52 move along the sliding groove 12 from the receiving plate 13 to one end of the sliding groove 12 near the feeding belt 22. The two abutting plates 512 are in contact with each other and abut against the second plate surface 82 of workpiece 8. If all four curvature detectors 5121 on the abutting plate 512 detect the plate surface of workpiece 8, then workpiece 8 is qualified. At the same time, the two clamping plates 513 clamp the workpiece 8 on opposite sides in the width direction of workpiece 8. When the four curvature detectors 5121 detect the second plate surface 82, they move towards the second distance sensor 513. 1. A signal is sent, and the second distance sensor 5131 measures the distance between the two clamping plates 513 and compares it with the width value preset by the PLC program. If it matches the preset width value, the width of the workpiece 8 is qualified; if it does not match, it is unqualified. The second distance sensor 5131 sends a signal to the receiving plate 13, and the receiving plate 13 moves toward the bottom of the sliding groove 12. When the first clamping block 51 is reset, it moves along the sliding groove 12 to one end of the sliding groove 12 and abuts against the groove wall. After the second pressure sensor 121 located in the sliding groove 12 detects the pressure, it sends a signal to the corresponding pusher cylinder 32. The corresponding pusher cylinder 32 drives the pusher block 33 to push the workpiece 8.

[0047] like Figure 6 and 7 As shown, the hole position detection component 6 is located in the third detection area. The hole position detection component 6 includes a connecting frame 61, at least two laser detectors 621, and a receiving block 631. The connecting frame 61 is fixedly connected to the worktable 1 and located above the workpiece 8, within the third detection area, and below the workpiece 8. A receiving plate 63 is fixedly connected to the worktable 1. In this embodiment, there are two mounting holes 83 on the workpiece 8, two laser detectors 621, and two receiving blocks 631. A connecting plate 62 is slidably connected to the connecting frame 61. Both laser detectors 621 are fixedly connected to the connecting plate 62, and both receiving blocks 631 are fixedly connected to the receiving plate 63. The spacing between the two laser detectors 621, the spacing between the two mounting holes 83, and the spacing between the two receiving blocks 631 are all the same. The feeding belt 22 carries the workpiece 8 to the third detection area. The connecting plate 62 carries the laser detector 621 and moves synchronously. The laser detector 621 continuously emits laser signals. If the two laser detectors 621 pass through the mounting hole 83 of the workpiece 8 synchronously, the receiving block 631 can receive the laser signal synchronously, and it can be determined that the hole position of the workpiece 8 is qualified. If the two receiving blocks 631 cannot receive the signal synchronously, it is determined that the hole position of the workpiece 8 is deviated, and the workpiece 8 is unqualified. At this time, the corresponding pusher cylinder 32 in the third detection area is activated, driving the pusher block 33 to push the workpiece 8 away from the feeding belt 22 and drop it into the recycling cart 7.

[0048] like Figure 6 As shown, if all dimensions of workpiece 8 pass inspection, the feeding belt 22 will continuously move workpiece 8. A receiving cart 14 is located on one side and below the workbench 1. The qualified workpieces 8 will eventually be collected into the receiving cart 14 for subsequent centralized bundling and transportation.

[0049] The implementation principle of the automatic detection device for photovoltaic frame processing in this application embodiment is as follows:

[0050] The inspector places the workpiece 8 on the feeding belt 22 and attaches the first plate surface 81 of the workpiece 8 to the feeding belt 22. The first moving block 43 and the second moving block 44 are used to inspect the workpiece 8's position. At the same time, the angle detection block 431 is used to detect the cutting angle of the two end faces of the workpiece 8. After passing the inspection, the feeding belt 22 continues to move with the workpiece 8. When it passes the actuating plate 922, the actuating plate 922 actuates the workpiece 8, so that the second plate surface 82 of the workpiece 8 is attached to the feeding belt 22. Moving to the second detection area, the first clamping block 51 and the second clamping block 52 move along the sliding groove 12, so that the abutment plate 512 abuts against the second plate surface 82 of the workpiece 8. The curvature detector 5121 set on the abutment plate 512 is used to detect the curvature of the second plate surface 82 of the workpiece 8. At the same time, the distance detector is used to measure the distance between the two clamping plates 513 to detect the width of the workpiece 8. After passing the test, the feeding belt 22 continues to carry the workpiece 8 to the third detection area. The laser detector 621 and the receiving block 631 cooperate to determine whether the hole position of the mounting hole 83 of the workpiece 8 is accurate.

[0051] During the entire automatic inspection process, if any workpiece is found to be of a non-conforming size, the pusher cylinder 32 drives the pusher block 33 to push the non-conforming workpiece 8 into the recycling cart 7. If all data of the workpiece 8 are found to be qualified, it is finally moved into the receiving cart 14 for centralized bundling and transportation.

[0052] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
