[0022] Specifically, a human-machine interaction device 14 is installed on one side of the device housing 11 , and the staff can control various devices in the photovoltaic welding ribbon 2 detection through the human-machine interaction device 14 .

[0023] Two mounting frames 111 are fixedly connected to the detection guide structure 1, one on the left and one on the right. Two guide wheels 112 are rotatably sleeved on the outside of the mounting frame 111, and one end of the unwound photovoltaic welding ribbon 2 is inserted into the device housing 11, so that one end of the photovoltaic welding ribbon 2 passes through the two guide wheels 112 at the rear side and then passes through the stepped curved plate 17 and the light-absorbing cloth 18 fixedly connected to the stepped curved plate 17. Four guide rods 113 are arranged at the bottom of the stepped curved plate 17, such as Figure 2 As shown, one end of the photovoltaic welding ribbon 2 passes through the top of the two top guide rods 113 and then passes through the bottom of the two bottom guide rods 113, and then one end of the photovoltaic welding ribbon 2 passes through between the two top guide rods 113 and then passes through the stepped curved plate 17 and the light-absorbing cloth 18, and finally one end of the photovoltaic welding ribbon 2 passes through the inside of the two front guide wheels 112 and then passes through the device housing 11 to the outside of the device housing 11 and is rolled up by the winding device; A plurality of mounting frames 114 are fixedly connected to one side of the device housing 11, so that the photovoltaic welding strip 2 passes through the plurality of U-shaped mounting frames 114, and a rubber sleeve 115 and two symmetrically arranged rubber sleeves 116 are rotatably sleeved on the outer sides of the plurality of mounting frames 114. Figure 5 As shown, the rotatable rubber sleeve 115 and the rubber sleeve 2 116 can limit and guide the photovoltaic welding ribbon 2, the mounting frame 3 114, the rubber sleeve 115 and the two rubber sleeves 116 form a guide member, and the multiple guide members are distributed on a longer inclined path. The photovoltaic welding ribbon 2 performs a small angle tilting movement under the action of the multiple guide members. Without damaging the photovoltaic welding ribbon 2, the portion of the photovoltaic welding ribbon 2 passing through the two rear guide wheels 112 and the portion of the photovoltaic welding ribbon 2 passing through the two front guide wheels 112 are at the same height. When the four guide rods 113 and the multiple guide members cooperate to turn downward, the portion of the photovoltaic welding ribbon 2 passing through the two rear guide wheels 112 is in a state of facing the camera 19 from the front, and the portion of the photovoltaic welding ribbon 2 passing through the two front guide wheels 112 is in a state of facing the camera 19 from the back, as shown in FIG. Figure 2 shown.

[0024] The photovoltaic welding ribbon intelligent detection method composed of the detection guide structure 1 and the detection simulation structure 3 is as follows: Step 1: Control the camera 19 to work. When the four guide rods 113 and multiple guide parts cooperate to turn downward, the camera 19 can simultaneously shoot the front and back sides of the photovoltaic welding ribbon 2, and provide data for the computer 16 to intelligently analyze the quality of the photovoltaic welding ribbon 2. The front and back sides of the photovoltaic welding ribbon 2 can be photographed and inspected at one time, reducing the time cost investment and number of operations required for the inspection of the photovoltaic welding ribbon 2, and reducing human damage to the photovoltaic welding ribbon 2.

[0025] Step 2: The pneumatic cylinder 1 31 in the detection simulation structure 3 installed inside the device housing 11 is inserted and fixed on the partition plate 15, and the fixing plate 32 fixedly installed at the piston end of the pneumatic cylinder 1 31 is fixedly connected with the mounting frame 4 33, as shown in FIG. Figure 6 As shown, when the control pneumatic cylinder 1 31 is working, the pneumatic cylinder 1 31 can control the up and down position of the mounting frame 4 33 through the fixing plate 32, and the ends of the mounting frame 6 313 and the mounting frame 4 33 close to each other are fixedly connected with the mounting frame 7 314, and the plurality of telescopic rods 315 are fixedly installed between the two mounting frames 7 314, as shown in FIG. Figure 7 As shown, under the action of the telescopic rod 315 and the mounting frame seven 314, the mounting frame six 313 and the mounting frame four 33 move up and down synchronously, and rubber plates 35 are arranged on the tops of the two right guide wheels one 112 and the two guide wheels two 310, and the tops of the four rubber plates 35 are fixedly connected with fixed vertical rods 34, of which two fixed vertical rods 34 are fixedly connected to the mounting frame four 33, and the other two fixed vertical rods 34 are fixedly connected to the mounting frame six 313, so the four rubber plates 35 move up and down synchronously with the mounting frame four 33 and the mounting frame six 313, so that the pneumatic cylinder one 31 can control the four rubber plates 35 to move up and down synchronously; The staff uses the human-computer interaction device 14 to control the operation of the pneumatic cylinder 31 in a timely manner, and controls the suspension of the reeling of the photovoltaic welding ribbon 2, so that the pneumatic cylinder 31 controls the four rubber plates 35 to move downward, two of which move toward the two guide wheels 112 on the right, and the two rubber plates 35 cooperate with the two guide wheels 112 to clamp the photovoltaic welding ribbon 2 at the upper position of the two guide wheels 112 on the right; the other two rubber plates 35 move toward the two guide wheels 2 310, and the two rubber plates 35 cooperate with the two guide wheels 2 310 to clamp the photovoltaic welding ribbon 2 at the upper position of the two guide wheels 2 310, so that the part of the photovoltaic welding ribbon 2 facing the camera 19 on the front side and the part of the photovoltaic welding ribbon 2 facing the camera 19 on the back side are clamped and limited at two positions.

[0026] Step 3: Control the operation of the pneumatic cylinder 2 316 in the position control component through the human-computer interaction device 14. Since the pneumatic cylinder 2 316 is fixedly inserted on the mounting frame 5 36, and the piston end of the pneumatic cylinder 2 316 is fixedly connected to the square tube 311, the operation of the pneumatic cylinder 2 316 can control the left and right position of the square tube 311. One end of the L-shaped column 312 inserted inside the square tube 311 is fixedly connected to the mounting frame 6 313. Therefore, the left and right movement of the square tube 311 drives the mounting frame 6 313 to move left and right through the L-shaped column 312. The mounting frame 4 33 is restricted by the pneumatic cylinder 1 31 and the fixed plate 32 and can only move left and right. The telescopic rod 315 installed between the mounting frame 4 33 and the mounting frame 6 313 can be telescoped, so the mounting frame 6 313 will not be affected by the mounting frame 4 33 when it moves left and right within a certain range. Both ends of the transverse axis 39 provided inside the mounting frame 5 36 are fixedly connected with protrusions 38, and guide grooves 37 are provided on both sides of the mounting frame 5 36, and two protrusions 38 are respectively inserted into the two guide grooves 37. Under the action of the protrusions 38 and the mounting frame 5 36, the transverse axis 39 cannot rotate on its own and can move left and right inside the mounting frame 5 36 fixedly installed on the equipment housing 11, and the square tube 311 is fixedly connected to one of the protrusions 38, so the square tube 311 can drive the transverse axis 39 to move synchronously through the protrusions 38; Therefore, when the pneumatic cylinder 2 316 controls the square tube 311 to move left and right, the horizontal axis 39 and the two guide wheels 2 310 mounted on the horizontal axis 39 will move left and right, and the square tube 311 will drive the mounting frame 6 313 to move left and right. The mounting frame 6 313 is fixed by two rubber plates 35 fixed by two fixed vertical rods 34 and the guide wheels 2 310 to move left and right synchronously while clamping the photovoltaic welding strip 2. Therefore, the pneumatic cylinder 2 316 is controlled to extend and push the square tube 311 to move right, so that the guide wheels 2 310 The guide wheel 112 moves to the right side, so that the part of the photovoltaic welding ribbon 2 that is clamped and fixed between the guide wheel 2 310 and the guide wheel 1 112 is wrinkled and bent, and then the pneumatic cylinder 2 316 drives the horizontal axis 39 and the mounting frame 6 313 to reset, which is a bending detection. After the control detection simulation structure 3 works to perform bending detection on the photovoltaic welding ribbon 2, the human-computer interaction device 14 controls the camera 19 to capture the image of the photovoltaic welding ribbon 2 after multiple bending at the bottom, and provides data for the computer 16 to intelligently analyze the quality of the photovoltaic welding ribbon 2; Step 4: Control the pneumatic cylinder 2 316 to apply a certain force to the left to the square tube 311, so that the horizontal axis 39 and the mounting frame 6 313 are subjected to a certain force to the left, so that the photovoltaic welding ribbon 2 located between the guide wheel 2 310 and the guide wheel 1 112 is subjected to tension. Then the pneumatic cylinder 2 316 stops working to unload the force, and the horizontal axis 39 and the mounting frame 6 313 are restored. This is a one-side stretching test. After multiple stretching tests, the camera 19 works to shoot the photovoltaic welding ribbon 2 to provide data support for the computer 16 to intelligently analyze the quality of the photovoltaic welding ribbon 2.

[0027] Step 5: A temperature control component is provided at the bottom of the mounting frame 5 36, and the winding device and the unwinding device are controlled to stop working for a period of time through the human-machine interaction device 14, so that the photovoltaic welding ribbon 2 stops moving, and then the heat exchanger 318 in the temperature control component and the exhaust fan 319 fixedly installed at the air inlet end of the heat exchanger 318 are controlled to work through the human-machine interaction device 14, and the isolation plate 317 is fixedly connected between the stepped curved plate 17 and the bottom wall of the inner cavity of the equipment housing 11, and when the door handle 13 fixedly installed on one side of the door body 12 is in the closed state, the door handle 1 3 is in close contact with the stepped curved plate 17 and the isolation plate 317. The equipment housing 11, the door handle 13, the stepped curved plate 17 and the isolation plate 317 form a relatively sealed environment simulation space. A guide pipe 1 320 is fixedly connected between the air inlet end of the exhaust fan 319 and the isolation plate 317. One end of the guide pipe 1 320 extends to the inside of the environment simulation space. Therefore, the exhaust fan 319 extracts air from the inside of the environment simulation space through the guide pipe 1 320. One end of the guide pipe 2 321 fixedly installed at the air outlet end of the heat exchanger 318 passes through the isolation plate 317. Figure 3 As shown, the exhaust fan 319 draws air flow and transports it to the inside of the heat exchanger 318. The heat exchanger 318 cools the air flow to a preset temperature and then transports it to the inside of the diverter box 322 fixedly connected to one end of the guide tube 321. The diverter box 322 is provided with multiple blowing holes 323 on the side close to the photovoltaic welding strip 2. The multiple blowing holes 323 spray cold air onto a larger area on one side of the photovoltaic welding strip 2, simulating the working condition of the photovoltaic welding strip 2 in a cold environment and providing data for the quality inspection of the photovoltaic welding strip 2.

[0028] Step six: After a period of time, the temperature control component is controlled to stop working, the winding device and the unwinding device are controlled to work, and the photovoltaic welding ribbon 2 moves normally, so that the contact position of the photovoltaic welding ribbon 2 and the low-temperature airflow sprayed by the temperature control component is suspended to the bottom of the camera 19, and the camera 19 works to shoot and collect data.

[0029] Step 7: Control the detection simulation structure 3 to perform steps 3 and 4, and collect data on multiple bending and stretching of the photovoltaic ribbon 2 in a low temperature environment.

[0030] The detection simulation structure 3 can be controlled to work, simulating the situation of the photovoltaic welding ribbon 2 after multiple bending and multiple stretching, as well as the situation of the photovoltaic welding ribbon 2 after multiple bending and stretching in a low temperature environment, so as to perform a relatively comprehensive quality inspection on the photovoltaic welding ribbon 2 at one time, ensure the reference value of the quality inspection result under the common use conditions of the photovoltaic welding ribbon 2, and reduce the time cost investment and staff operation steps required for the inspection of the photovoltaic welding ribbon 2.

[0031] In addition, such as Figure 2 As shown, the detection guide structure 1 includes a camera 19 and a computer 16. The camera 19 is arranged on the top of the photovoltaic welding strip 2. The partition plate 15 fixedly connected to the bottom of the computer 16 is fixedly connected to the device housing 11, which completely separates the computer 16 from the detection simulation structure 3 to prevent the operation of the detection simulation structure 3 from affecting the safety of the computer 16. The mounting frame 110 fixedly mounted on the outside of the camera 19 is fixedly connected to the device housing 11, and the camera 19 is installed on the top of the photovoltaic welding strip 2.

[0032] In addition, such as Figure 2 and Fig.11 As shown, a stepped bent plate 17 is fixedly installed inside the device housing 11, and a light-absorbing cloth 18 is fixedly connected to the side of the stepped bent plate 17 close to the mounting frame 111. The light-absorbing cloth 18 is arranged at the bottom of the camera 19 to serve as a shooting background to prevent reflective objects other than the photovoltaic welding strip 2 in the shooting path of the camera 19 from affecting the shooting results.

[0033] In addition, the CNC program and PLC control program are stored inside the human-computer interaction device 14 and cooperate with the electrical components inside the device housing 11 to realize the automatic control of the camera 19 and the related equipment in the detection simulation structure 3, which is a common public technology; the trained detection model is stored inside the computer 16 to perform quality inspection on the photovoltaic welding strip 2, which is a common public technology. The public technology is not elaborated in this application, and the specific application can be designed according to actual needs.

[0034] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
