[0028] Therefore, the present utility model provides a CCS automatic hot riveting welding detection production line.

[0029] In the embodiments of the present utility model, please refer to Figure 1 , the CCS automatic hot riveting welding detection production line includes a loading workbench 10, a processing device 20 and a detection device 30. The loading workbench 10 is used for loading aluminum bars, substrates and nickel sheets. The processing device 20 is arranged adjacent to the loading workbench 10 and is used for processing the aluminum bars, substrates and nickel sheets to form a CCS integrated busbar. The detection device 30 is arranged on one side of the processing device 20 away from the loading workbench 10 and is used for quality inspection of the processed CCS integrated busbar.

[0030] In this embodiment, after the loading workbench 10 moves the carrier into place, the blocking mechanism on the loading workbench 10 rises to block the carrier. At this time, the staff manually loads the substrate, aluminum bar and nickel sheet onto the carrier. Then the loading workbench 10 is started, and the carrier on which the substrate, aluminum bar and nickel sheet have been placed is driven to flow out of the loading workbench 10. The carrier will be scanned by the scanner provided on the loading workbench 10 at the moment of flowing out, and the nickel sheet QR code will be entered into the main controller of the CCS automatic hot riveting welding inspection production line. The loading workbench 10 loads the carrier plates with the aluminum bar, the substrate and the nickel sheet to the processing equipment 20 respectively. When the carrier plates with the aluminum bar, the substrate and the nickel sheet are moved to the processing equipment 20, the processing equipment 20 will hot rivet the aluminum bar and the substrate together, and then weld the aluminum bar and the nickel sheet together, thereby completing the processing of the CCS integrated busbar; the assembled CCS integrated busbar is then moved to the testing equipment 30, and the testing equipment 30 is used to directly perform various inspections, so that the CCS integrated busbar can be processed and inspected at one time, and there is no need to transfer the processed CCS integrated busbar to the testing equipment 30 for further processing, thereby improving the working efficiency of the CCS automatic hot riveting welding inspection production line.

[0031] In one embodiment, see Figure 1 The processing equipment 20 includes a multi-point hot riveting machine 21 and a laser welding machine 22. The multi-point hot riveting machine 21 is arranged adjacent to the loading workbench 10, and the multi-point hot riveting machine 21 is used to hot rivet the aluminum bar and the substrate; the laser welding machine 22 is arranged on a side of the multi-point hot riveting machine 21 away from the loading workbench 10, and the laser welding machine 22 is used to weld the nickel sheet and the aluminum bar.

[0032] Specifically, the processing equipment 20 is provided with a multi-point hot riveting machine 21 and a laser welding machine 22 to cooperate in the hot riveting process and the welding process of the aluminum bar, the substrate and the nickel sheet; wherein the pressure of the hot riveting head of the multi-point hot riveting machine 21 is adjusted by a spring, and the welding pressure is not affected by the fluctuation of the gas source pressure, and it has multiple hot riveting positions, which improves the hot riveting efficiency of the multi-point hot riveting machine 21. The main unit of the multi-point hot riveting machine 21 has a built-in integrated design and strong anti-interference ability. The floor-standing design is convenient for transportation and wiring. The multi-point hot riveting machine 21 also adopts a special temperature feedback riveting head, and the heating-maintaining-cooling process is all real-time temperature acquisition + PID control. The laser welding machine 22 welds the aluminum bar and the nickel sheet in a non-contact manner, reducing the impact on the aluminum bar and the nickel sheet, thereby improving the welding effect of the aluminum bar and the nickel sheet.

[0033] In one embodiment, see Figure 1 The multi-point hot riveting machine 21 includes a casing, a driving member and a positioning plate. The driving member is installed in the casing, and the positioning plate is lifted and connected to the outer wall of the casing and is transmission-connected to the driving member; the positioning plate is detachably connected with a universal hot riveting head and a special hot riveting head, and the universal hot riveting head and the special hot riveting head are arranged at intervals and are used to hot-rivet the aluminum bar and the substrate together.

[0034] Specifically, by arranging a driving member and a positioning plate inside the casing of the multi-point hot riveting machine 21, the driving member is used to drive the positioning plate to lift inside the casing, so that the general hot riveting head and the special hot riveting head arranged on the positioning plate can also lift inside the casing, realizing the change of the distances between the general hot riveting head and the special hot riveting head and the aluminum bar and the substrate, and improving the hot riveting effect of the multi-point hot riveting machine 21.

[0035] The general hot riveting head can be applied to the hot riveting of aluminum bars and substrates of multiple models, while the special hot riveting head can be replaced according to the hot riveting requirements of aluminum bars and substrates of different models, thereby increasing the hot riveting range of the multi-point hot riveting machine 21.

[0036] In one embodiment, please refer to Figure 1 , the detection device 30 includes an insulation withstanding voltage tester 31, a comprehensive tester 32, an AOI detector 33 and a Pin pin detector 34. The insulation withstanding voltage tester 31, the comprehensive tester 32, the AOI detector 33 and the Pin pin detector 34 are arranged and connected in sequence. The insulation withstanding voltage tester 31 is adjacent to the side of the laser welding machine 22 away from the multi-point hot riveting machine 21.

[0037] Specifically, the upper and lower layer PET films of the insulation withstanding voltage tester 31 are applied with high voltage through conductive cotton and a carrier, and the probe contacts the Busbar to detect that the leakage current is less than 1 mA within 2 s; the type withstanding voltage tester is a single-channel withstanding voltage tester. The upper and lower PET film carriers and the conductive cotton are in contact and DC2700V, 2S, and the short circuit with a leakage current less than 1 mA is used as the pressurizing end, and all Busbar probes are in contact and shorted as the withstanding voltage test end. Since the impedance of the product to be tested by the comprehensive tester 32 is small and the contact impedance between the probe and the product cannot be ignored, only the four-wire four-terminal test method can be used. At the same time, the environment where the test fixture and the product are placed in the equipment is constant temperature and constant humidity, considering the influence of temperature and humidity on the micro-resistance to generate temperature drift. Finally, a scheme of separately testing the micro-resistance and the withstanding voltage with two machines is adopted. The AOI detector 33 automatically scans the CCS integrated busbar through a high-definition CCD camera, collects images, compares the detected points of the test with the qualified parameters in the database, and after image processing, checks for defects on the target product, and displays / marks the defects through a display or an automatic sign for maintenance personnel to repair and SMT engineers to improve the process. Through the above-mentioned detection device 30 to detect the CCS integrated busbar in multiple aspects in this case, it is convenient to eliminate the CCS integrated busbars with unqualified quality, thereby improving the quality of the CCS integrated busbar.

[0038] In one embodiment, please refer to Figure 1 , the CCS automatic hot riveting welding detection production line further includes a cooling table 40. The cooling table 40 is arranged between the laser welding machine 22 and the insulation withstanding voltage tester 31 and is used to cool the welded CCS integrated busbar.

[0039] By arranging a cooling table 40 between the laser welding machine 22 and the insulation voltage withstand testing machine 31, the cooling table 40 can cool the CCS integrated busbar after welding, reduce the temperature of the CCS integrated busbar, so that the insulation voltage withstand testing machine 31 will not be affected by high temperature factors when detecting the CCS integrated busbar, and improve the detection accuracy of the insulation voltage withstand testing machine 31 for the CCS integrated busbar.

[0040] In one embodiment, please refer to Figure 1 , the CCS automatic hot riveting welding detection production line further includes a blanking workbench 50, and the blanking workbench 50 is adjacent to the side of the Pin pin detector 34 away from the AOI detector 33. The blanking workbench 50 is used to blank the qualified CCS busbar.

[0041] After the blanking workbench 50 moves the carrier plate in place, the blocking mechanism on the blanking workbench 50 rises to block the carrier plate from moving. At this time, the staff manually blanks the CCS integrated busbar to other positions, realizing the blanking speed of the CCS integrated busbar, and thus improving the working efficiency of the CCS automatic hot riveting welding detection production line.

[0042] In one embodiment, please refer to Figure 1 , the CCS automatic hot riveting welding detection production line further includes a first lifting table 60, and the first lifting table 60 is adjacent to the side of the loading workbench 10 away from the processing equipment 20.

[0043] Specifically, the first lifting table 60 is arranged on the starting side of the loading workbench 10. After the carrier plate moves to the first lifting table 60, the stopper of the first lifting table 60 will rise to block the carrier plate from continuing to move, facilitating the staff to place the substrate, aluminum bar and nickel sheet on the carrier plate; when the CCS integrated busbar is formed by processing and the detection process is completed and the detection result is qualified, the staff will move the CCS integrated busbar to the blanking workbench 50 for blanking.

[0044] In one embodiment, please refer to Figure 1 , the CCS automatic hot riveting welding detection production line further includes a second lifting table 70, and the second lifting table 70 is adjacent to the side of the detection equipment 30 away from the processing equipment 20.

[0045] Specifically, the second lifting table 70 is arranged on the starting side of the loading workbench 10. When the CCS integrated busbar is formed by processing and the detection process is completed and the detection result is qualified, the staff will move the CCS integrated busbar to the blanking workbench 50 for blanking. At this time, the carrier plate is in an empty state. The second lifting table 70 lowers the empty carrier plate to the blanking position, facilitating the carrier plate to flow back to the position of the first lifting table 60.

[0046] In one embodiment, please refer to Figure 1The CCS automatic hot riveting welding inspection production line also includes a transmission track, which runs through the loading workbench 10, the processing equipment 20 and the inspection equipment 30, and is used to transmit aluminum bars, substrates and nickel sheets between the loading workbench 10, the processing equipment 20 and the inspection equipment 30.

[0047] Specifically, the transmission track in this case uses an anti-static transmission belt, which eliminates the static impact of the product during the production process. The transmission track adopts a modular structure design and an automatic detection device. After the track is unloaded for a certain period of time, it automatically enters a static state to save energy.

[0048] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
