Technical Field

[0001] The utility model relates to the technical field of photovoltaic frames, in particular to an appearance detection device for photovoltaic frames. Background Art

[0002] The photovoltaic frame is an important component of the photovoltaic module, located in the middle and lower reaches of the photovoltaic industry chain. The frame is an important part of the solar photovoltaic module, which plays a role in encapsulating materials such as battery chips, glass, and backplanes, enhancing the strength of the module, facilitating transportation, installation, and protecting the photovoltaic module. The product is required to have strong bearing capacity and corrosion resistance; the performance of the photovoltaic frame has a direct impact on the installation and service life of the battery module. The manufacturing process of the photovoltaic aluminum frame is divided into four stages: melting and casting, extrusion, oxidation, and deep processing.

[0003] At present, after the deep processing of the photovoltaic frame is completed, enterprises often need to conduct appearance detection on it to determine whether the production of the product meets the standards. The existing detection methods for photovoltaic frames usually include machine inspection and manual inspection. After the photovoltaic frame is stamped, the photovoltaic frame is conveyed to the inspection table by the conveying component to detect the processing size, and then the surface is manually inspected one by one for scratches, black spots, uneven color, etc., which is time-consuming and laborious, greatly increasing the labor intensity of workers. Content of the Utility Model

[0004] The purpose of the utility model is to solve the shortcomings that the existing detection methods for photovoltaic frames usually include machine inspection and manual inspection. After the photovoltaic frame is stamped, the photovoltaic frame is conveyed to the inspection table by the conveying component to detect the processing size, and then the surface is manually inspected one by one for scratches, black spots, uneven color, etc., which is time-consuming and laborious, greatly increasing the labor intensity of workers, and to propose an appearance detection device for photovoltaic frames.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An appearance detection device for photovoltaic frames includes a conveying component and a vision system. The conveying component includes a connecting frame, rollers, and a transmission mechanism for driving the rollers to rotate. A flipping component is arranged in the middle of the connecting frame. The flipping component includes a first flipping plate, a second flipping plate, and a rotating component. A rotating assembly is arranged between the first flipping plate and the second flipping plate. The rotating assembly includes a bracket, a gear, and a second driving member. The bracket is movably connected to the gear. An outer cover is installed on the conveying component.

[0007] By adopting the above technical solution, the material to be detected is conveyed to the second turning plate of the turning assembly through the rollers on the conveying assembly. Then, after the first driving member of the turning assembly operates, the first turning plate of the turning assembly rotates counterclockwise by [X] degrees. Then, through the operation of the second driving member of the rotating assembly, the second driving member uses a micro stepping motor to make the corresponding gear rotate at a low speed, realizing the turning action of the material to be detected. And through the anti-slip sheet wrapped outside the gear, the friction between the gear and the material to be detected is increased, so that the gear can smoothly drive the material to be detected to perform the turning adjustment action when rotating at a low speed, completing the multi-sided turning work of the part to be detected, enabling the subsequent vision system to smoothly transmit the pictures taken of each fixed frame of the material to be detected to the external display device to complete the appearance detection work, which is beneficial to improving the appearance detection work of the material to be detected, greatly reducing the labor intensity of workers, saving time and effort.

[0008] Preferably, the output shaft of the second driving member penetrates through the bracket and is fixedly connected to the gear. The teeth of the gear are wrapped with an anti-slip sheet. The bracket is of a U-shaped structure, and the outer wall of the second driving member is fixedly connected to the outer wall of the bracket.

[0009] Preferably, the bracket and the rotating member form a detachable structure through screws, and the number of brackets is equal to the number of first turning plates.

[0010] Preferably, the rotating member includes a main rotating rod and a baffle. The connection between the baffle and the main rotating rod is connected through a bearing.

[0011] Preferably, a first driving member is installed outside the baffle. The output shaft of the first driving member is connected to the end of the main rotating rod, and the outer wall of the first driving member is fixedly connected to the outer wall of the baffle.

[0012] Preferably, a lifting assembly is arranged below the baffle. The lifting assembly includes a telescopic member, and a fixing frame is installed at the bottom of the telescopic member. Both ends of the fixing frame are connected to the inner side of the connecting frame.

[0013] Preferably, the baffle and the fixing frame form a lifting mechanism through the telescopic member.

[0014] Preferably, the vision system includes a CCD camera, an image processing module, and a light source. The CCD camera is arranged in the middle of the inner top of the outer cover, and the vision system is electrically connected to an external control system.

[0015] Preferably, a dust blowing system is installed on the outer cover. The dust blowing system includes a suction pump and air outlets, and the air outlets are distributed on the inner wall of the inner side of the outer cover.

[0016] In summary, due to adopting the above technical solution, the beneficial effects of the present utility model are:

[0017] 1. In the present utility model, after the flipping assembly rotates the material to be detected by 45 degrees, the second driving member on the rotating assembly drives the gear to rotate intermittently at a low speed, so that the material to be detected is in a state of turning over and pausing, realizing multi-sided flipping work. This enables the smooth driving of the material to be detected for multi-sided turning-over actions, facilitating the multi-sided appearance inspection of the part to be detected through mechanical turning-over actions, improving the efficiency of the appearance inspection work of the material to be detected, greatly reducing the manual labor intensity, and saving time and effort.

[0019] 3. In the present utility model, through the action of the suction pump and the air outlet on the dust blowing system, it is convenient to blow clean the material to be detected on the first flipping plate and the second flipping plate, so that there are no attachments on the surface of the material to be detected, which affects the subsequent appearance inspection, and it has high practicability.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] Referring to Figures 1-4 , a photovoltaic frame appearance detection device includes a conveying assembly 1 and a vision system 6. The conveying assembly 1 includes a connecting frame 101, a roller 102, and a transmission mechanism 103 for driving the roller 102 to rotate. A flipping assembly 2 is provided in the middle of the connecting frame 101. The flipping assembly 2 includes a first flipping plate 201, a second flipping plate 202, and a rotating member 203. A rotating assembly 3 is provided between the first flipping plate 201 and the second flipping plate 202. The rotating assembly 3 includes a bracket 301, a gear 302, and a second driving member 304. The bracket 301 is movably connected to the gear 302. An outer cover 4 is installed on the conveying assembly 1.

[0028] By adopting the above technical solution, the material to be detected passes through the roller 102 on the conveying assembly 1 and is conveyed to the second flipping plate 202 of the flipping assembly 2. Then, after the first driving member 204 of the flipping assembly 2 works, the first flipping plate 201 of the flipping assembly 2 rotates counterclockwise by 45 degrees. Then, through the work of the second driving member 304 of the rotating assembly 3, the second driving member 304 adopts a micro stepping motor, so that the corresponding gear 302 rotates at a low speed, realizing the flipping action of the material to be detected. And through the anti-slip sheet 303 wrapped on the gear 302, the friction between the gear 302 and the material to be detected is increased, so that when the gear 302 rotates at a low speed, it can smoothly drive the material to be detected to perform the flipping adjustment action, completing the multi-sided flipping work of the part to be detected, enabling the subsequent vision system 6 to smoothly transmit the pictures taken of each static surface of the material to be detected to an external display device to complete the appearance detection work, which is beneficial to improving the appearance detection work of the material to be detected, greatly reducing the labor intensity of manual work, and saving time and effort.

[0029] As Figure 3 shown in Figure 4 , the output shaft of the second driving member 304 penetrates through the bracket 301 and is fixedly connected to the gear 302. The teeth of the gear 302 are wrapped with an anti-slip sheet 303. The bracket 301 is in a U-shaped structure, and the outer wall of the second driving member 304 is fixedly connected to the outer wall of the bracket 301.

[0030] By adopting the above technical solution, through the anti-slip sheet 303 adhered to the external teeth of the gear 302, the anti-slip sheet 303 is a rubber gasket with anti-slip patterns, and the external part of the bracket 301 is also covered with a rubber sheet. When the gear 302 contacts the material to be detected under the covering of the anti-slip sheet 303, it will not produce a rigid collision with it. At the same time, through the anti-slip patterns, the friction between the gear 302 and the material to be detected can be increased, enabling the multi-faceted rotation of the material to be detected to be driven smoothly. The second driving member 304 adopts a micro stepping motor, so that the corresponding gear 302 started can rotate at a low speed, and the rotation speed of the driving component is adjusted by changing the pulse frequency, current magnitude or winding switching of the control system, realizing the turning and freezing actions of the material to be detected.

[0031] Further, the bracket 301 and the rotating member 203 form a detachable structure through screws, and the number of brackets 301 is equal to the number of the first flipping plates 201.

[0032] By adopting the above technical solution, through the detachable structure of the bracket 301 and the main rotating rod 2032 of the rotating member 203, it is convenient to replace the gear 302 on the bracket 301 according to the specifications of the material to be detected, enabling the turning work of the material to be detected to proceed smoothly.

[0033] Such as Figure 3 And Figure 4 As shown, the rotating member 203 includes a main rotating rod 2032 and a baffle 2031, and the connection between the baffle 2031 and the main rotating rod 2032 is connected through a bearing.

[0034] By adopting the above technical solution, when the first driving member 204 drives the main rotating rod 2032 to rotate, the rotation action can be carried out smoothly.

[0035] Specifically, a first driving member 204 is installed outside the baffle 2031. The output shaft of the first driving member 204 is connected to the end of the main rotating rod 2032, and the outer wall of the first driving member 204 is fixedly connected to the outer wall of the baffle 2031. When the first driving member 204 works, it drives the main rotating rod 2032 to rotate, enabling the first flipping plate 201 and the second flipping plate 202 on the main rotating rod 2032 to carry out the rotating work on the material to be detected, facilitating the appearance detection work on the material to be detected. This design has a simple structure, is practical, has a high utilization rate, and a wide application range.

[0036] Such as Figure 1 And Figure 2 As shown, a lifting assembly 7 is provided below the baffle 2031. The lifting assembly 7 includes a telescopic member 701. The bottom of the telescopic member 701 is installed with a fixing frame 702, and both ends of the fixing frame 702 are connected to the inner side of the connecting frame 101. The telescopic member 701 adopts a hydraulic telescopic cylinder.

[0037] Specifically, the baffle 2031 and the fixed frame 702 form a lifting mechanism through the telescopic member 701.

[0038] By adopting the above technical solution, when the telescopic member 701 of the lifting assembly 7 drives the baffle 2031 to move up and down within the connecting frame 101, the position of the main rotating rod 2032 can be adjusted. After the flipping assembly 2 flips the material to be detected by 45 degrees, the telescopic member 701 is convenient to push the main rotating rod 2032 upward, so that the rotating assembly 3 on the main rotating rod 2032 moves out from the gap between the rollers 102, and the flipping work on the part to be detected is carried out, which is convenient for subsequent appearance detection.

[0039] Preferably, the vision system 6 includes a CCD camera 601, an image processing module 602 and a light source 603. The CCD camera 601 is arranged in the middle of the inner top end of the outer cover 4, and the vision system 6 is electrically connected to an external control system.

[0040] By adopting the above technical solution, the area of the material to be detected is illuminated by the light source 603, so that the pictures of the items taken by the CCD camera 601 are clearer, which is beneficial to improving the quality of appearance detection.

[0041] As Figure 1 shown in Figure 2 Figure, a dust blowing system 5 is installed on the outer cover 4. The dust blowing system 5 includes a suction pump 501 and an air outlet 502, and the air outlets 502 are distributed on the inner wall of the inner side of the outer cover 4.

[0042] By adopting the above technical solution, it is convenient to blow clean the material to be detected on the first flipping plate 201 and the second flipping plate 202, so that there are no attachments on the surface of the material to be detected to affect the subsequent appearance detection, which has high practicability.

[0043] Working principle: After the material to be inspected that has completed dimensional inspection is sent onto the conveying component 1 of this device through the conveying device of the production line, it is conveyed to one side of the flipping component 2 through the roller 102 on the conveying component 1. After the first driving part 204 of the flipping component 2 works, the first flipping plate 201 of the flipping component 2 rotates counterclockwise and / or clockwise by 45 degrees, placing the material to be inspected under the CCD camera 601 of the vision system 6. Through the work of the second driving part 304 of the rotating component 3, the second driving part 304 uses a micro stepping motor, making the corresponding gear 302 rotate at a low speed. By changing the pulse frequency, current magnitude or winding switching of the control system to adjust the rotation speed of the driving part, the turning and freezing action of the material to be inspected is realized. And through the anti-slip sheet 303 wrapped outside the gear 302, the friction between the gear 302 and the material to be inspected is increased, enabling the gear 302 to smoothly drive the material to be inspected to perform the turning adjustment action when rotating at a low speed, completing the multi-sided flipping work of the part to be inspected. Then, the vision system 6 transmits the pictures taken of each frozen surface of the material to be inspected to an external display device for appearance inspection work, which is beneficial to improving the appearance inspection work of the material to be inspected, greatly reducing the labor intensity of workers, and saving time and effort.
