[0022] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the specific implementation manner of the present application will be clearly and completely described below in conjunction with the drawings in the present application.

[0023] like Figure 1 As shown, the present application provides a detection device 100 , which is used for appearance detection of a photovoltaic component 200 .

[0024] In order to clearly illustrate the technical solution of this application, the following is also defined: Figure 1 Front, back, left, right, up and down as shown.

[0025] The detection device 100 includes an outer frame 110, a first frame detection mechanism 120 and a second frame detection mechanism 130. The first frame detection mechanism 120 is fixedly connected to the outer frame 110, and the second frame detection mechanism 130 has a degree of freedom of movement relative to the detection device 100. The first frame detection mechanism 120 and the second frame detection mechanism 130 respectively detect the appearance quality of the adjacent two sides of the photovoltaic module 200.

[0026] The projection of the photovoltaic module 200 along the vertical direction of the detection device 100 is basically a rectangle. Therefore, the frame of the photovoltaic module 200 includes a long frame and a short frame, and the first frame detection mechanism 120 and the second frame detection mechanism 130 can respectively shoot and detect the frame appearance and frame glue line of the long frame and the short frame on the photovoltaic module 200, thereby improving the integration of the detection device 100, and the detection of the frame appearance and frame glue line of the photovoltaic module 200 can be completed in one detection device 100, thereby shortening the production line length of the detection device 100 of the photovoltaic module 200 and reducing the floor space of the production line.

[0027] More specifically, the second inspection mechanism 130 inspects the long frame of the photovoltaic module 200. Since the inspection range required for the long frame is larger than the inspection range for the short frame, the second inspection mechanism 130 with the freedom of movement can perform a mobile appearance quality inspection on the long frame, so that the second inspection mechanism 130 can inspect the complete long frame of the photovoltaic module 200, thereby improving the inspection integrity of the photovoltaic module 200 by the inspection device 100.

[0028] like Figure 2 , Figure 3 and Figure 4 As shown, as an implementation, the structure of the first border detection mechanism 120 is the same as the structure of the second border detection mechanism 130 .

[0029] Specifically, the first frame detection mechanism 120 includes a connection base 121, a first bracket 122, a second bracket 123, a frame camera 124 and a frame light source 125. The connection base 121 is fixedly connected to the outer frame 110 to achieve fixed installation of the first frame detection mechanism 120, so that the first frame detection mechanism 120 can detect the short frame of the photovoltaic module 200.

[0030] Specifically, the second frame detection mechanism 130 includes a connection base 131, a first bracket 132, a second bracket 133, a frame camera 134 and a frame light source 135. The connection base 131 has a degree of freedom of movement relative to the outer frame 100, which can facilitate the second frame detection mechanism 130 to detect the long frame of the photovoltaic module 200.

[0031] Since the first frame detection mechanism 120 and the second frame detection mechanism 130 have the same structure, the present application takes the structure of the first frame detection mechanism 120 as an example for explanation, and does not elaborate on the structure of the second frame detection mechanism 130.

[0032] In the present application, the first bracket 122 and the second bracket 123 are at least partially connected to the connection base 121. The frame camera 124 is fixedly connected to the first bracket 122, and the frame camera 124 is used to shoot and detect the short frame of the photovoltaic module 200; the frame light source 125 is fixedly connected to the second bracket 123, and the frame light source 125 is used to illuminate the short frame of the photovoltaic module 200, so as to cooperate with the frame camera 124 to shoot and improve the shooting clarity of the frame camera 124.

[0033] Among them, the first bracket 122 and the second bracket 123 both have rotational freedom relative to the connecting seat 121, so as to realize the rotation adjustment of the first bracket 122 and the second bracket 123. More specifically, through the rotation adjustment of the first bracket 122, the frame camera 124 can be rotationally adjusted, so that the frame camera 124 can focus on the short frame of the photovoltaic component 200, which is conducive to improving the clarity of the frame camera 124 shooting the short frame of the photovoltaic component 200. Through the rotation adjustment of the second bracket 123, the frame light source 125 can be rotationally adjusted, so that the frame light source 125 can be moved according to the shooting position of the frame camera 124, which is conducive to cooperating with the shooting detection of the frame camera 124.

[0034] Further, a horizontal plane 101 (refer to Figure 1 ), the shooting direction of the frame camera 124 intersects with the horizontal plane 101, and the irradiation direction of the frame light source 125 intersects with the horizontal plane 101, so that the frame camera 124 can perform tilted shooting of the photovoltaic module 200, and the frame light source 125 can perform tilted illumination of the photovoltaic module 200. Among them, the tilted frame camera 124 can facilitate focusing on the short frame of the photovoltaic module 200, and at the same time, the irradiation position of the frame light source 125 basically coincides with the shooting position of the frame camera 124, and the irradiation of the frame light source 125 improves the shooting clarity of the frame camera 124.

[0035] Furthermore, the number of the first frame detection mechanism 120 and the second frame detection mechanism 130 are both set to two. The two first frame detection mechanisms 120 respectively shoot and detect the two short frames on the photovoltaic module 200, and the two second frame detection mechanisms 130 respectively shoot and detect the two long frames on the photovoltaic module 200. In this way, the integrity of the frame of the photovoltaic module 200 is achieved, and there will be no omission in the detection, thereby improving the detection accuracy of the frame of the photovoltaic module 200 by the first frame detection mechanism 120 and the second frame detection mechanism 130.

[0036] like Figure 5 As shown, as an embodiment, the first bracket 122 is rotatably connected to the connecting seat 121 through a pivot shaft 1221. The first bracket 122 is also provided with an arc hole 1222 for limiting the rotation range of the first bracket 122, and the arc hole 1222 extends along an arc segment, and the center of the arc segment is located on the axis of the pivot shaft 1221. A limiting column 1213 is provided on the connecting seat 121, and the limiting column 1213 is always located in the arc hole 1222. The first bracket 122 and the connecting seat 121 are rotatably connected through the pivot shaft 1221, so as to adjust the rotation angle of the first bracket 122; at the same time, the setting of the arc hole 1222 can cooperate with the limiting column 1213 to rotate around the pivot shaft 1221, so as to limit the rotation range of the first bracket 122, so as to avoid the rotation angle of the first bracket 122 being too large, resulting in 124 being in a position where 200 cannot be photographed, thereby improving the shooting accuracy of 124.

[0037] Among them, the connection method between the first bracket 122 and the connecting seat 121 is the first connection method, and the connection method between the second bracket 123 and the connecting seat 121 is the second connection method. The first connection method is the same as the second connection method, so that the first bracket 122 and the second bracket 123 can both rotate relative to the connecting seat 121, thereby adjusting the angle of the first bracket 122 and the second bracket 123 relative to the connecting seat 121, and then the frame light source 125 can also rotate relative to the connecting seat 121 to adjust the angle of the frame light source 125 relative to the connecting seat 121, so as to cooperate with the frame camera 124 to illuminate the photovoltaic component 200 and improve the shooting clarity of the frame camera 124.

[0038] As an embodiment, the outer wall of the limiting column 1213 is provided with an external thread, so that a locking nut can be installed on the limiting column 1213, and tightening the locking nut can fix the first bracket 122 or the second bracket 123 to the connecting seat 121, thereby avoiding the shaking of the first bracket 122 during the shooting detection process, and improving the connection stability of the first bracket 122 and the second bracket 123 with the connecting seat 121. In addition, loosening the locking nut can make the first bracket 122 and the second bracket 123 rotate relative to the connecting seat 121, thereby adjusting the angles of 124 and 125.

[0039] It should be noted that the locking nut is a fixing method for fixing the first bracket 122 and the second bracket 123 to the connecting base 121, and the present application does not limit the fixing method of the first bracket 122 or the second bracket 123 to the connecting base 121.

[0040] like Figure 3 and Figure 4 As shown, as an embodiment, the connection seat 121 includes a seat body 1211 and a side plate 1212. The connection seat 131 includes a seat body 1311 and a side plate 1312. The seat body 1211 is fixedly connected to the outer frame 110, and the seat body 1311 has a degree of freedom of movement relative to the outer frame 110.

[0041] Since the structures of the connection socket 121 and the connection socket 131 are the same, the present application takes the connection socket 121 as an example and does not repeat the structure of the connection socket 131.

[0042] Specifically, the side plate 1212 has a degree of freedom of movement relative to the base 1211, and can be moved and adjusted relative to the base 1211. The first bracket 122 and the second bracket 123 are both mounted on the side plate 1212. Through the above arrangement, the movement of the side plate 1212 can drive the first bracket 122 and the second bracket 123 to move relative to the base 1211, thereby increasing the movement and adjustment positions of the first bracket 122 and the second bracket 123. When adjusting the frame camera 124 for rotational focus and / or adjusting the frame light source 125 for lighting, the adjustment positions of the frame camera 124 and the frame light source 125 can be increased, which facilitates the frame camera 124 to focus and shoot the photovoltaic module 200 and the frame light source 125 to illuminate the photovoltaic module 200.

[0043] Specifically, a waist-shaped hole 1211a for connecting the side plate 1212 is provided on the base 1211, and the extension direction of the waist-shaped hole 1211a intersects with the horizontal plane 101, wherein the side plate 1212 has a degree of freedom of movement along the extension direction of the waist-shaped hole 1211a relative to the base 1211. Thus, in the extension direction of the waist-shaped hole 1211a, the side plate 1212 can adjust the installation position to drive the first bracket 122 and the second bracket 123 to move along the extension direction of the waist-shaped hole 1211a, and then the distance between the first bracket 122 and the second bracket 123 and the photovoltaic module 200 can be adjusted, so that the frame camera 124 can find a suitable angle to shoot the photovoltaic module 200, and it is beneficial for the frame light source 125 to find a suitable angle to illuminate the photovoltaic module 200.

[0044] It should be noted that the extension direction of the waist-shaped hole 1211a may also be parallel to the horizontal plane 101, and this application does not impose any limitation thereto.

[0045] As an embodiment, the side plate 1212 and the base 1211 can be fixed by bolts and nuts. Specifically, the bolt passes through the waist-shaped hole 1211a and the side plate 1212, the head of the bolt abuts against the side plate 1212 or the base 1211, and the nut is fixed to the side of the bolt away from the head to achieve the fixation between the side plate 1212 and the base 1211.

[0046] In the present application, tightening the nut can compress the base 1211 and the side plate 1212, thereby fixing the base 1211 and the side plate 1212, thereby preventing the side plate 1212 from sliding in the waist-shaped hole 1211a during the shooting and detection process. In addition, loosening the nut can make the side plate 1212 slide in the waist-shaped hole 1211a to adjust the position of the first bracket 122 and the second bracket 123.

[0047] It should be noted that the connection method of bolts and nuts is a connection method between the side plate 1212 and the seat body 1211. The present application can also realize the connection with the waist-shaped hole 1211a by interference fitting the side plate 1212 into the waist-shaped hole 1211a by plugging and unplugging the side plate 1212. Therefore, the present application does not limit the connection method between the side plate 1212 and the seat body 1211.

[0048] like Figure 1 , Figure 2 and Figure 6 As shown, as an embodiment, the detection device 100 further includes a driving assembly 140, which is fixedly connected to the outer frame 110, and the driving assembly 140 is in transmission connection with the second frame detection mechanism 130, so that the driving assembly 140 drives the second frame detection mechanism 130 to move. The moving direction of the second frame detection mechanism 130 driven by the driving assembly 140 is parallel to the extension direction of the long frame of the photovoltaic module 200, thereby realizing the quality detection of the long frame of the photovoltaic module 200.

[0049] As an embodiment, the driving assembly 140 includes a slide rail cylinder, which is fixedly connected to the outer frame 110 and is transmission-connected to the second frame detection mechanism 130. The slide rail cylinder drives the second frame detection mechanism 130 to move along an extension direction of the long frame parallel to the photovoltaic assembly 200.

[0050] like Figure 1As shown, as an embodiment, the detection device 100 further includes a first surface detection mechanism 150 and a second surface detection mechanism 160. The first surface detection mechanism 150 is fixedly connected to the outer frame 110, and the first surface detection mechanism 150 is located above the photovoltaic assembly 200, so that the first surface detection mechanism 150 can detect the upper surface of the photovoltaic assembly 200. The second surface detection mechanism 160 is fixedly connected to the outer frame 110, and the second surface detection mechanism 160 is located below the photovoltaic assembly 200, so that the second surface detection mechanism 160 can detect the lower surface of the photovoltaic assembly 200. The first surface detection mechanism 150 and the second surface detection mechanism 160 can be used to detect the quality of the upper surface and the lower surface of the photovoltaic module 200. In conjunction with the first frame detection mechanism 120 and the second frame detection mechanism 130 that are simultaneously arranged on the outer frame 100, the upper surface quality detection, the lower surface quality detection and the frame quality detection of the photovoltaic module 200 can be completed on one detection device, thereby further improving the integration of the detection device 100, shortening the production line length of the detection device 100, and reducing the floor space occupied by the production line.

[0051] Furthermore, the minimum distance between the first surface detection mechanism 150 and the second surface detection mechanism 160 along the up and down direction of the detection device 100 is greater than the thickness of the photovoltaic component 200 along the up and down direction of the detection device 100, thereby avoiding collision and interference between the photovoltaic component 200 and the first surface detection mechanism 150 and the second surface detection mechanism 160.

[0052] like Figure 1 As shown, as an implementation manner, the structure of the first surface detection mechanism 150 is the same as the structure of the second surface detection mechanism 160 .

[0053] Specifically, the first surface detection mechanism 150 includes a detection camera 151 and a detection light source 152 ; the second surface detection mechanism 160 includes a detection camera 161 and a detection light source 162 .

[0054] Since the structure of the first surface detection mechanism 150 is the same as that of the second surface detection mechanism 160 , the present application takes the first surface detection mechanism 150 as an example and does not elaborate on the structure of the second surface detection mechanism 160 .

[0055] In this embodiment, the detection camera 151 is fixedly connected to the outer frame 110, and the detection camera 151 is used to photograph the appearance quality of the upper surface of the photovoltaic module 200. The detection light source 152 is connected to the outer frame 110, and the detection light source 152 is used to illuminate the upper surface of the photovoltaic module 200, so as to cooperate with the detection camera 151 to improve the shooting clarity of the detection camera 151.

[0056] Among them, both the detection camera 151 and the detection light source 152 have a rotational freedom relative to the outer frame 110, so that the detection camera 151 and the detection light source 152 can be rotated and adjusted. The shooting angle of the detection camera 151 can be adjusted by rotating the detection camera 151, so that the detection camera 151 focuses on the upper surface of the photovoltaic component 200. The lighting angle of the detection light source 152 can be adjusted by rotating the detection light source 152, so as to cooperate with the detection camera 151 to illuminate the upper surface of the photovoltaic component 200, and the lighting position of the detection light source 152 and the shooting position of the detection camera 151 are basically coincident, so as to facilitate improving the shooting clarity of the detection camera 151.

[0057] like Figure 1 and Figure 6 As shown, as an embodiment, the detection device 100 further includes a moving mechanism 170, and the moving mechanism 170 is supported by the outer frame 110. Specifically, the moving mechanism 170 is used to support the photovoltaic assembly 200 and drive the photovoltaic assembly 200 to move to the detection position. The photovoltaic assembly 200 is driven to move by the moving mechanism 170 to achieve the purpose of automatic transmission of the photovoltaic assembly 200, thereby improving the moving efficiency of the photovoltaic assembly 200 in the detection device 100.

[0058] In this embodiment, the moving mechanism 170 includes a motor 171, a driving wheel 172, a driven wheel 173 and a conveyor belt 174. The motor 171 is fixedly connected to the outer frame 110. The driving wheel 172 is transmission-connected to the motor 171. The driven wheel 173 is rotationally connected to the outer frame 110, and the driving wheel 172 and the driven wheel 173 are respectively arranged at the front and rear ends of the outer frame 110. The front and rear ends of the conveyor belt 174 are transmission-connected to the driving wheel 172 and the driven wheel 173 respectively.

[0059] Specifically, the photovoltaic assembly 200 is placed on the conveyor belt 174, and the motor 171 drives the driving wheel 172 to rotate, and cooperates with the driven wheel 173 to drive the conveyor belt 174 to rotate, so that the conveyor belt 174 can drive the photovoltaic assembly 200 to move to the detection position.

[0060] like Figure 6 As shown, as an implementation manner, the detection device 100 further includes a blocking mechanism 180 , and the blocking mechanism 180 is fixedly connected to the outer frame 110 .

[0061] The blocking mechanism 180 includes a first separation position separated from the photovoltaic assembly 200 and a first abutment position abutting against the photovoltaic assembly 200. When the moving mechanism 170 drives the photovoltaic assembly 200 to move to the detection position, the blocking mechanism 180 moves from the first separation position to the first abutment position, so that the photovoltaic assembly 200 can be positioned to improve the positioning accuracy of the photovoltaic assembly 200 on the moving mechanism 170, thereby preventing the photovoltaic assembly 200 from moving to a position that cannot be detected by the first frame detection mechanism 120 and the second frame detection mechanism 130, so as to improve the detection accuracy of the detection device 100 on the photovoltaic assembly 200.

[0062] Specifically, the blocking mechanism 180 includes a blocking cylinder 181 and a blocking wheel 182. The blocking cylinder 181 is fixedly connected to the outer frame 110; the blocking cylinder 181 is in transmission connection with the blocking wheel 182, and the blocking cylinder 181 drives the blocking wheel 182 to move in the up-down direction of the detection device 100. The blocking wheel 182 has a rotational freedom relative to the blocking cylinder 181, and the rotation axis of 182 extends substantially in the up-down direction of the detection device 100. When the photovoltaic component 200 is in the detection position, the blocking cylinder 181 drives the blocking wheel 182 to move upward to the first abutment position, so that the blocking wheel 182 abuts against the photovoltaic component 200 to limit the position, so as to facilitate the first frame detection structure 120 and the second frame detection mechanism 130 to detect the photovoltaic component 200; after the detection of the photovoltaic component 200 is completed, the blocking cylinder 181 drives the blocking wheel 182 to move downward to the first separation position, so that the blocking wheel 182 no longer abuts against the photovoltaic component 200, so as to facilitate the photovoltaic component 200 to be moved out of the detection equipment 100 through the moving mechanism 170.

[0063] like Figure 6 As shown, as an implementation, the detection device 100 further includes a correction mechanism 190 , and the correction mechanism 190 is fixedly connected to the outer frame 110 .

[0064] Among them, the correction mechanism 190 includes a second separation position separated from the photovoltaic component 200 and a second abutment position abutting against the photovoltaic component 200. When the moving mechanism 170 drives the photovoltaic component 200 to move to the detection position, the correction mechanism 190 moves from the second separation position to the second abutment position, thereby realizing the positioning of the photovoltaic component 200, so as to facilitate driving the photovoltaic component 200 to move to the detection position for detection, thereby improving the detection accuracy of the first frame detection mechanism 120 and the second frame detection mechanism 130 on the photovoltaic component 200.

[0065] Specifically, the correction mechanism 190 is also provided with a guide wheel 191, and the guide wheel 191 abuts against the photovoltaic assembly 200. The number of the correction mechanisms 190 is set to two, and the two correction mechanisms 190 are distributed along the moving direction perpendicular to the photovoltaic assembly 200. When the correction mechanism 190 drives the guide wheel 191 to move to the second abutment position, the setting of the two correction mechanisms 190 can clamp and position the left and right ends of the photovoltaic assembly 200 at the same time, so that the short frame of the photovoltaic assembly 200 basically extends along the front and rear direction of the detection device 100, thereby driving the photovoltaic assembly 200 to move to the detection position, facilitating the cooperation with the first frame detection mechanism 120 and the second frame detection mechanism 130 for quality detection, avoiding the situation that the photovoltaic assembly 200 does not reach the detection position and causing incomplete detection, thereby improving the detection accuracy of the photovoltaic assembly 200 by the first frame detection mechanism 120 and the second frame detection mechanism 130.

[0066] In this embodiment, the correction mechanism 190 also includes a correction cylinder 192 and a connecting rod 193, wherein the correction cylinder 192 is fixedly connected to the outer frame 110; the correction cylinder 192 is transmission-connected to the connecting rod 193; and the guide wheel 191 is connected to the connecting rod 193. Among them, the guide wheel 191 has a rotational freedom relative to the connecting rod 193, and the rotation axis of the guide wheel 191 extends substantially along the up-and-down direction of 100. The extension direction of the connecting rod 193 is parallel to the moving direction of the photovoltaic assembly 200, and the number of guide wheels 191 on each connecting rod 193 is two, and the guide wheels 191 are arranged at the front and rear ends of the connecting rod 193. By setting two guide wheels 191, a two-point push can be achieved in the process of positioning against the photovoltaic assembly 200, thereby making the push of the guide wheel 191 on the photovoltaic assembly 200 more stable, and the photovoltaic assembly 200 will not tilt.

[0067] When the photovoltaic assembly 200 is in the detection position, the return cylinder 192 drives the connecting rod 193 to drive the guide wheel 191 to move to the second contact position to abut against the photovoltaic assembly 200, so that the return mechanism 190 can cooperate with the blocking mechanism 180 to position the photovoltaic assembly 200, so as to facilitate the first frame detection mechanism 120 and the second frame detection mechanism 130 to accurately detect the photovoltaic assembly 200. After the detection of the photovoltaic assembly 200 is completed, the return cylinder 192 drives the connecting rod 193 to drive the guide wheel 191 to move to the second separation position, so that the guide wheel 191 will not interfere with the movement of the photovoltaic assembly 200.

[0068] In this embodiment, two first frame detection mechanisms 120 are disposed at the left and right ends of the outer frame 110 to detect the short frames at the left and right ends of the photovoltaic assembly 200 .

[0069] The second detection mechanism 130 is disposed behind the second frame detection mechanism 120 , and two second detection mechanisms 130 are disposed at the front and rear ends of the outer frame 110 to detect the long frames at the front and rear ends of the photovoltaic assembly 200 .

[0070] The driving assembly 140 drives the second detection mechanism 120 to move along the extension direction of the long frame of the photovoltaic assembly 200 , so that the second frame detection mechanism 130 can detect the long frame.

[0071] Specifically, the first frame detection mechanism 120 and the second frame detection mechanism 130 are both disposed above the photovoltaic assembly 200 .

[0072] The first surface detection mechanism 150 and the second surface detection mechanism 160 are both arranged in front of the first frame detection mechanism 120. The first surface detection mechanism 150 is arranged above the photovoltaic assembly 200 to detect the upper surface of the photovoltaic assembly 200. The second surface detection mechanism 160 is arranged below the photovoltaic assembly 200 to detect the lower surface of the photovoltaic assembly 200.

[0073] The moving mechanism 170 drives the photovoltaic assembly 200 to move in the front-rear direction.

[0074] The blocking mechanism 180 is disposed behind the moving mechanism 170 to block the photovoltaic assembly 200 .

[0075] Two alignment mechanisms 190 are disposed at the left and right ends of the outer frame 110 to achieve abutment and positioning of the left and right ends of the photovoltaic assembly 200 .

[0076] In this application, the working principle of the detection device 100 is as follows:

[0077] First, the photovoltaic module 200 enters the moving mechanism 170 in the detection device 100 from between the first surface detection mechanism 150 and the second surface detection mechanism 160. The upper surface of the photovoltaic module 200 is photographed and detected by the first surface detection mechanism 150, and the lower surface of the photovoltaic module 200 is photographed and detected by the second surface detection mechanism 160, thereby realizing the quality detection of the upper and lower surfaces of the photovoltaic module 200.

[0078] Secondly, the moving mechanism 170 drives the photovoltaic assembly 200 to move to the detection position. The blocking mechanism 180 moves to the first abutting position to abut against the photovoltaic assembly 200, and the correcting mechanism 190 moves to the second abutting position to abut against the photovoltaic assembly 200, thereby limiting the photovoltaic assembly 200 to the detection position, which is beneficial to the quality detection of the first frame detection mechanism 120 and the second frame detection mechanism 130.

[0079] After the photovoltaic assembly 200 is restricted to the detection position, the first frame detection mechanism 120 detects the left and right sides (i.e., the short frame of the photovoltaic assembly 200) of the photovoltaic assembly 200. At the same time, the second frame detection mechanism 130 is driven by the driving assembly 140 to move along the left and right direction of the detection device 100, so that the second frame detection mechanism 130 detects the front and back sides (i.e., the long frame of the photovoltaic assembly 200) of the photovoltaic assembly 200.

[0080] During the appearance quality inspection of the photovoltaic module 200, the first surface inspection mechanism 150, the second surface inspection mechanism 160, the first frame inspection mechanism 120 and the second frame inspection mechanism 130 located on the outer frame 110 can perform a comprehensive appearance inspection of the photovoltaic module 200, so that the appearance inspection of the photovoltaic module 200 can be completed in one device. Through the above settings, the integration of the inspection device 100 is high, the production line of the inspection device 100 is short, and there is no need to perform back-and-forth judgment between multiple inspection devices 100, which is convenient for operators to operate and improves the appearance inspection efficiency of the photovoltaic module 200.

[0081] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to this application.
