As the air in the air pressure control mechanism is reciprocated and compressed, the compressed air is further compressed into the connected deep cleaning assembly, causing the elastic airbag to inflate and expand, pushing the cleaning part to move. Thus, during the reciprocating polishing, the cleaning brush on the cleaning part of the deep cleaning assembly further reciprocates against the copper busbar, achieving cleaning treatment for the groove defects or gap defects of the copper busbar, avoiding blockages from affecting the subsequent filling of the fluorescent mixture, and providing accuracy of the detection results by effectively cleaning the blockages in the copper busbar defects.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figures 1 to 11 As shown, this embodiment of the invention provides a copper busbar surface inspection device, including a base 1 and a support frame 2 fixed to the side of the base 1. A composite drive assembly 9 is fixedly provided on the top of the base 1, and a reciprocating pushing mechanism is also provided on the top of the base 1. A mounting frame 5, a coating treatment mechanism 3, and a defect detection assembly 7 are sequentially spaced on the side of the support frame 2. A trimming treatment mechanism 6 is movably fitted inside the mounting frame 5. An auxiliary supply mechanism 4 is connected to the top of the coating treatment mechanism 3. A coating cleaning part 8 is provided at the end of the defect detection assembly 7. The front end of the copper busbar passes through the trimming treatment mechanism 6, the coating treatment mechanism 3, the coating cleaning part 8, and the defect detection assembly 7 in sequence. The coating treatment mechanism 3 coats the copper busbar with an internal fluorescent solution. The defect detection assembly 7 detects the residual fluorescent solution after the copper busbar is cleaned by the coating cleaning part 8. The composite drive assembly 9 controls the reciprocating pushing mechanism to move synchronously, and causes the trimming treatment mechanism 6 to slide back and forth and causes the auxiliary supply mechanism 4 to intermittently squeeze the internal fluorescent solution.

[0022] Example 1: In use, the rectangular copper busbar to be inspected is inserted along the trimming mechanism 6 inside the mounting frame 5, passes through the coating mechanism 3, and passes through the defect detection component 7. During inspection, the external drive mechanism causes the rectangular copper busbar to move laterally, activating the composite drive component 9. The motor 91 in the composite drive component 9 is activated, driving the gear 92 to rotate, which in turn drives gear 14 and gear 2 16 to rotate, causing cam 13 and cam 2 15 to rotate. As cam 2 15 rotates, it pushes the contact block 63 in the trimming mechanism 6. With the elasticity of spring 14, the movable frame 61 slides back and forth along the inside of the mounting frame 5, scraping off protruding particles and burrs from the outer surface of the copper busbar, polishing the surface, and completing the oxide layer treatment. As cam 13 rotates, the rectangular copper busbar moves laterally. The auxiliary supply mechanism 4 below is pushed and compressed, causing the pressure plate 42 in the auxiliary supply mechanism 4 to reciprocate and compress the fluorescent mixture stored inside the connecting frame 41. This causes the fluorescent mixture with a certain viscosity to be squeezed along the inside of the frame 31 and the inner ring cavity 33 in the coating treatment mechanism 3 onto the outer surface of the internally sleeved rectangular copper busbar. Under pressure, the fluorescent mixture fills and penetrates into the surface cracks and depressions of the previously treated copper busbar. As the copper busbar moves out, when it passes through the coating cleaning section 8, the cleaning inner frame 82 scrapes off the fluorescent liquid attached to the surface. The fluorescent liquid embedded in the cracks and depressions remains on the copper busbar. When it passes through the defect detection component 7, the fluorescent detection section 73 inside the defect detection component 7 detects and identifies whether there is fluorescence on the four outer surfaces of the copper busbar. When it is detected, it is determined that there is a defect on the outer surface of the copper busbar.

[0023] First, by utilizing the trimming mechanism 6, composite drive assembly 9, coating mechanism 3, auxiliary supply mechanism 4, defect detection assembly 7, reciprocating push mechanism, and coating cleaning unit 8, the copper busbar is transported and inspected. Surface treatment is performed through the wire to remove burrs and flash, and to remove protruding particles from the surface, completing the pre-surface processing of the copper busbar. After processing, a fluorescent mixture containing viscous liquid is promptly applied to the surface of the copper busbar. The reciprocating compression auxiliary supply mechanism 4 enhances the effect of the fluorescent mixture filling and penetrating the defects on the surface of the copper busbar. This, combined with surface scraping after coating, allows the fluorescent detection unit 73 to identify and detect the copper busbar after surface scraping. The solution in the grooves and cracks covered by surface scraping is used to achieve fluorescent detection, thus completing defect detection. For the copper busbar, defect detection is completed in various areas during transport, especially the identification and detection of surface grooves and cracks. Simultaneously, surface processing and polishing of the copper busbar are also completed during inspection, achieving simultaneous processing while completing inspection.

[0024] Furthermore, by reusing the trimming mechanism 6, the composite drive assembly 9, and the reciprocating push mechanism, and combining them with the deep cleaning assembly 11 and the air pressure control mechanism 12, during the inspection process, as the composite drive assembly 9 and the reciprocating push mechanism cause the trimming mechanism 6 to reciprocate, the reciprocating push mechanism also simultaneously activates the air pressure control mechanism 12. As the air in the air pressure control mechanism 12 is reciprocated and compressed, the compressed air is further compressed into the connected deep cleaning assembly 11, causing the elastic airbag 111 to inflate and expand, pushing the cleaning part 112 to move. Thus, during the reciprocating polishing, the cleaning brush on the cleaning part 112 in the deep cleaning assembly 11 further reciprocates against the copper busbar, achieving cleaning treatment for the copper busbar groove defects or gap defects, avoiding blockages from affecting the subsequent filling of the fluorescent mixture, and improving the accuracy of the inspection results by effectively cleaning the blockages in the copper busbar defects.

[0025] Example 2: During the inspection process, as the trimming mechanism 6 reciprocates, the four outer surfaces of the copper busbar are deburred, have burrs, flash, and oxide layers removed under friction treatment. At the same time, the surface temperature of the copper busbar rises. As the dynamically treated copper busbar continues to be transported to the oxidation detection unit 10, the temperature detector 103 in the inner ring cavity 102 senses and collects the temperature of the four outer surfaces of the copper busbar in the corresponding area, and transmits the data to the control terminal. After comparing the data with the data after the normal copper busbar is heated by friction, the presence of high-temperature areas is identified, and the presence of oxidation marks on the surface of the copper busbar is identified.

[0026] First, by reciprocating the reciprocating motion of the finishing mechanism 6, the surface temperature of the copper busbar is raised during finishing and polishing, and the surface oxide layer is removed. For the oxide layer marks after cleaning, the outer surface of the copper busbar is heated by the heating effect after contact polishing. Taking advantage of the difference in thermal conductivity between the copper busbar body and the oxide layer marks, after the grinding and heating, the temperature detector 103 in the oxidation detection unit 10 senses and detects the surface temperature of the copper busbar after finishing. For any abnormally high temperature points, the presence of oxide marks on the copper busbar is identified, and further inspection of the copper busbar is completed.

[0027] The coating processing mechanism 3 includes a frame 31, an outer frame 32, and an inner ring cavity 33. The outer frame 32 is fixedly sleeved on the outer side of the frame 31. The inner ring cavity 33 is opened on the inner wall of the frame 31 and communicates with the interior of the outer frame 32. The fluorescent liquid is mixed with an adhesive. The auxiliary supply mechanism 4 includes a connecting frame 41, a pressure plate 42, a top plate 43, and a middle rod 44. The connecting frame 41 is fixed on the top of the outer frame 32 and communicates with the interior of the outer frame 32. The pressure plate 42 is movably sleeved in the connecting frame 41. The top plate 43 is elastically connected above the connecting frame 41. The middle rod 44 is fixedly connected between the pressure plate 42 and the top plate 43 and moves through the top of the connecting frame 41.

[0028] The coating treatment mechanism 3 guides the liquid supply from four sides through its internal mechanism. In the non-detection stage, the socket frame can be fitted into the coating treatment mechanism 3 to achieve a seal. When the copper busbar is fitted, it is automatically filled. The auxiliary supply mechanism 4 opens through the sealing port (not shown in the figure) on the side to add the viscous fluorescent mixture. On the other hand, it is pushed by the reciprocating pushing mechanism to achieve reciprocating extrusion. The extrusion action ensures that there is pressure in the coating treatment mechanism 3 and further compresses the viscous fluorescent mixture into the cracks of the copper busbar. By enhancing the penetration effect, it ensures subsequent detection.

[0029] The trimming mechanism 6 includes a movable frame 61, a side frame 62, a contact block 63, and a spring 64. The movable frame 61 is movably fitted inside the mounting frame 5. The side frame 62 is fixed to the outside of the movable frame 61. The contact block 63 is fixed to the inner wall of the side frame 62. One end of the spring 64 is fixed to the inner wall of the side frame 62, and the other end of the spring 64 is fixed to the mounting frame 5.

[0030] The finishing mechanism 6, through reciprocating motion, generates relative movement with the copper busbar that is fitted and moved, completing surface polishing and simultaneously removing burrs and flash. It can also effectively handle abnormal protrusions on the surface.

[0031] The defect detection component 7 includes a frame 71, an inner ring cavity 72, and a fluorescence detection unit 73. The inner ring cavity 72 is formed on the inner wall of the frame 71, and the fluorescence detection unit 73 is disposed in the four side areas of the inner ring cavity 72. The coating and cleaning unit 8 includes a fixed sleeve 81 and a cleaning inner frame 82. The fixed sleeve 81 is fixed to the end of the frame 71, and the cleaning inner frame 82 is fixedly sleeved in the fixed sleeve 81.

[0032] The defect detection component 7, together with the coating and cleaning unit 8, completes the squeezing and scraping of the fluorescent liquid in the non-defective areas after coating, and the fluorescent detection unit 73 in the defect detection component 7 detects the four sides of the copper busbar, thus quickly completing the defect detection of the rectangular copper busbar.

[0033] The reciprocating drive mechanism includes cam 13, gear 14, cam 2 15, and gear 2 16. Cam 13 and cam 2 15 are rotatably mounted on the support plate via intermediate shafts and bearings. There are two support plates, both fixed to the top of the base 1. Gear 14 is fixedly sleeved on the intermediate shaft of cam 13, and gear 2 16 is fixedly sleeved on the intermediate shaft of cam 2 15. When cam 13 rotates, it reciprocates to push the top plate 43. When cam 2 15 rotates, it reciprocates to push the contact block 63. The composite drive assembly 9 includes a motor 91 and a drive gear 92. The motor 91 controls the drive gear 92 to rotate. The drive gear 92 simultaneously meshes with gear 14 and gear 2 16.

[0034] The reciprocating push mechanism and the composite drive component 9 cooperate with each other to realize the rotation of cam 13 and cam 2 15 under rotation. The rotation of cam 13 completes the reciprocating compression of the auxiliary supply mechanism 4. Cam 2 15 realizes the lateral reciprocating action of the trimming and processing mechanism on the one hand, and reciprocatingly controls the action of the air pressure control mechanism 12 on the other hand, to complete the reciprocating action of the deep cleaning component 11.

[0035] The trimming and processing mechanism 6 has a deep cleaning component 11 inside. The top of the mounting frame 5 has a pneumatic control mechanism 12, which is connected to the deep cleaning component 11. The reciprocating pushing mechanism also controls the deep cleaning component 11 to reciprocate in expansion and contraction via the pneumatic control mechanism 12. The deep cleaning component 11 includes an elastic airbag 111, a cleaning part 112, and a guide frame 113. The mounting frame 5 has a reserved cavity 17 inside. The elastic airbag 111 is nested on the inner wall of the movable frame 61. The cleaning part 112 is fixed to the inner side of the elastic airbag 111. The guide frame 113... Fixed to the top of the movable frame 61, the movable frame 61 is located in the reserved cavity 17 and is connected to the elastic airbag 111. The air pressure control mechanism 12 includes an air storage box 121, a push plate 122, a bottom plate 123 and a second intermediate rod 124. The air storage box 121 is fixed to the top of the mounting frame 5. The push plate 122 is elastically sleeved in the air storage box 121. The second intermediate rod 124 is fixedly connected to the bottom of the push plate 122. The movable end of the second intermediate rod 124 moves through the bottom of the air storage box 121 and is fixedly connected to the bottom plate 123. The bottom plate 123 abuts against the outer side of the second cam 15.

[0036] By utilizing the reciprocating compression of the air pressure control mechanism 12, the connected deep cleaning component 11 reciprocates, and strengthens the squeezing and cleaning of the outer surface of the copper busbar in the trimming mechanism 6. In conjunction with the cleaning brush in the deep cleaning component 11, the grooves and cracks on the outer surface of the copper busbar are effectively cleaned.

[0037] Among them, the side of the support frame 2 is fixedly provided with an oxidation detection unit 10. The oxidation detection unit 10 detects the surface temperature of the copper busbar after being processed by the trimming mechanism 6. The oxidation detection unit 10 includes a frame 3 101, an inner ring cavity 3 102 and a temperature detector 103. The inner ring cavity 3 102 is opened inside the frame 3 101, and the temperature detector 103 is arranged in the four corresponding chambers of the inner ring cavity 3 102.

[0038] By using the oxidation detection unit 10 in conjunction with the finishing processing mechanism 6, the outer surface temperature of the copper busbar after being heated by the finishing processing mechanism 6 is detected. By utilizing the difference in thermal conductivity between the copper busbar itself and the surface oxide marks, and by utilizing the characteristics of the oxide zone, which exhibits higher temperature rise and slower cooling due to its low thermal conductivity and different surface properties, the abnormally high temperature area after friction heating is identified by distinguishing it from the normal copper busbar temperature, thus identifying the presence of residual oxidation marks on the copper busbar and expanding the detection range.

[0039] The working principle and usage process of this invention are as follows: During use, the rectangular copper busbar to be inspected is inserted along the trimming mechanism 6 inside the mounting frame 5, passes through the interior of the coating mechanism 3, and passes through the defect detection component 7. During inspection, the external drive mechanism causes the rectangular copper busbar to move laterally, activating the composite drive component 9. This activates the motor 91 within the composite drive component 9, driving the gear 92 to rotate, which in turn drives gear 14 and gear 2 16 to rotate, causing cam 13 and cam 2 15 to rotate. As cam 2 15 rotates, it pushes the trimming mechanism... The contact block 63 in the coating mechanism 6, in conjunction with the elasticity of the spring 64, causes the movable frame 61 to slide back and forth along the inside of the mounting frame 5, scraping off protruding particles and burrs from the outer surface of the copper busbar inside, while simultaneously polishing the surface and completing the oxide layer treatment. As the cam 13 rotates, it reciprocates and pushes the auxiliary supply mechanism 4 below, causing the pressure plate 42 in the auxiliary supply mechanism 4 to reciprocate and compress the fluorescent mixture stored inside the connecting frame 41. This causes the fluorescent mixture, with a certain viscosity, to spread along the inside of the frame 31 and the inner ring cavity 33 within the coating treatment mechanism 3. The fluorescent liquid is squeezed onto the outer surface of the internally sleeved rectangular copper busbar. Under pressure, the fluorescent liquid fills and penetrates into the surface cracks and depressions of the previously treated copper busbar. As the copper busbar moves out, when it passes through the coating and cleaning section 8, the cleaning inner frame 82 scrapes off the fluorescent liquid adhering to the surface. The fluorescent liquid built into the cracks and depressions remains on the copper busbar. When it passes through the inside of the defect detection component 7, the fluorescent detection section 73 inside the defect detection component 7 detects and identifies whether there is fluorescence on the four outer surfaces of the copper busbar. When it is detected and identified, it is determined that there is a defect on the outer surface of the copper busbar. During the inspection process, as the trimming mechanism 6 reciprocates, the four outer surfaces of the copper busbar are deburred, have burrs, flash, and oxide layers removed through friction. Simultaneously, the surface temperature of the copper busbar increases. As the dynamically processed copper busbar continues to be transported to the oxidation detection unit 10, the temperature detector 103 in the inner ring cavity 102 senses and collects the temperature of the four outer surfaces of the copper busbar in the corresponding area, and transmits the data to the control terminal. After comparing the data with that of a normal copper busbar after friction and temperature rise, the presence of high-temperature areas is identified, and areas with oxide marks on the surface of the copper busbar are identified.

[0040] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
