Testing the withstand voltage of the copper busbar is to test the insulation withstand voltage performance of the copper busbar's insulation layer, and testing the insulation withstand voltage performance of the copper busbar's insulation layer is to test the maximum voltage that the copper busbar's insulation layer can withstand without breakdown.

[0003] At present, the existing copper busbar withstand voltage test is usually carried out using a withstand voltage tester. The copper busbar usually includes a copper conductor A, a copper conductor B, and an insulating layer that insulates the copper conductor A and the copper conductor B. When testing the withstand voltage of the copper busbar, the positive and negative poles of the test line of the withstand voltage tester are connected to the copper conductor A and the copper conductor B respectively, the withstand voltage tester is started, and the test voltage is applied according to the set test conditions. The display screen of the withstand voltage tester is observed, and the voltage and current changes during the test are monitored. When the insulation layer breaks down, the withstand voltage tester sends an alarm signal or displays that the test result is unqualified, so as to achieve the purpose of the copper busbar withstand voltage test.

[0024] Please refer to Figure 1-Figure 13 The present invention provides an automated copper busbar withstand voltage test device, comprising a base 1, an industrial computer (not shown), a rotating mechanism 2, a labeling device 3, a label scanning unit 4, a leak detection device 5, a withstand voltage test device 6, a material taking device 7 and a conveying system 8.

[0025] Fig.14 Schematic diagram of the structure of the copper busbar 9 of this embodiment.

[0026] Reference Figure 1-Figure 5A fixed disk 10 is fixed on the base 1, and an industrial computer (industrial control computer) is arranged on the base 1. The industrial computer serves as the control system of the copper busbar withstand voltage test automation equipment. The rotating mechanism 2 is arranged on the base 1. Of course, the rotating mechanism 2 is controlled by the industrial computer. Among them, the rotating mechanism 2 includes a first driving unit 21 and a rotating disk 22. The rotating disk 22 is rotatably arranged on the base 1. The rotating disk 22 is coaxial with the fixed disk 10. The fixed disk 10 is located above the rotating disk 22. A positioning fixture 20 is fixed on the rotating disk 22. The positioning fixture 20 is used to position and fix the copper busbar 9 to be tested. The first driving unit 21 is arranged on the base 1, and is used to drive the rotating disk 22 to rotate. The first driving unit 21 is connected to the industrial computer, and the first driving unit 21 uses a driving motor. Before the copper busbar withstand voltage test automation equipment is started, the positioning fixture 20 is located at the loading station 102 on the corresponding base 1. At this time, the operator positions and fixes the copper busbar 9 on the positioning fixture 20. After the copper busbar 9 is positioned and fixed on the positioning fixture 20, the industrial computer controls the first drive unit 21 to drive the rotating disk 22 to rotate to start the operation of the equipment. During loading, in order to identify whether the copper busbar 9 is fixed on the positioning fixture 20, an identification sensor 101 controlled by the industrial computer is set on the fixed disk 10. After the operator positions and fixes the copper busbar 9 on the positioning fixture 20, the identification sensor 101 identifies and senses that there is a copper busbar 9 on the positioning fixture 20. At this time, the industrial computer controls the first drive unit 21 to drive the rotating disk 22 to rotate clockwise.

[0027] Reference Figure 1-Figure 3 and Figure 6-Figure 7The labeling device 3 is controlled by the industrial computer and is arranged on the base 1. The labeling device 3 is used to attach the label to the labeling position on the copper bus 9 positioned on the positioning fixture 20. That is, it can be understood that when the positioning fixture 20 rotates to the station corresponding to the labeling device 3, the labeling device 3 attaches the label to the labeling position on the copper bus 9. The labeling device 3 includes a labeling machine 30, a label peeling mechanism (not shown), a label conveying mechanism 31 and a labeling mechanism 32, all of which are arranged on the base 1. The labeling machine 30 is used to provide a label with release paper, and the label peeling mechanism is used to peel the label on the release paper onto the label conveying mechanism 31. The labeling mechanism 32 absorbs the label on the label conveying mechanism 31 by vacuum adsorption and attaches the label to the labeling position on the copper bus 9. Among them, the labeling machine 30 uses the existing labeling machine 30, and the label peeling mechanism also uses the existing label peeling mechanism, that is, how the label peeling mechanism peels the label with release paper onto the label conveying mechanism 31 belongs to the prior art. The label conveying mechanism 31 includes an electric cylinder 310 and a sliding plate 311. The electric cylinder 310 is controlled by an industrial computer and is fixed on the base 1. The telescopic end of the electric cylinder 310 is drive-connected to the sliding plate 311. The sliding plate 311 is slidingly arranged on the outer shell of the electric cylinder 310 along the horizontal Y direction. When the electric cylinder 310 drives the sliding plate 311 to slide to the label outlet position of the label machine 30, the label peeling mechanism peels the label with release paper output by the label machine 30 to the upper surface of the sliding plate 311. At this time, the sliding plate 311 is driven by the electric cylinder 310 to move out of the label outlet position of the label machine 30.

[0028] Reference Figure 1 and Figure 6The labeling mechanism 32 includes a support seat 320, a first linear module 321, a first lifting unit 322 and a rotating label mechanism 323. The support seat 320 is fixed on the base 1 in the vertical direction, the first linear module 321 is arranged on the support seat 320 in the horizontal X direction, the slider of the first linear module 321 is connected with a mounting seat 3210, and the rotating label mechanism 323 is arranged on the mounting seat 3210 in a vertical sliding manner. The rotating label mechanism 323 is used to absorb the label on the label conveying mechanism 31, and the rotating label mechanism 323 is also used to drive the absorbed label to rotate. Driven by the first linear module 321, the rotating label mechanism 323 can move to the top of the label conveying mechanism 31 or the top of the positioning fixture 20; the first lifting unit 322 is fixed on the mounting seat 3210, and the lifting end of the first lifting unit 322 is drivingly connected to the rotating label mechanism 323. The first lifting unit 322 is used to drive the rotating label mechanism 323 to absorb the label on the label conveying mechanism 31, and the first lifting unit 322 is also used to enable the rotating label mechanism 323 to attach the label to the copper bus 9 of the positioning fixture 20. Specifically, it can be understood that when the electric cylinder 310 drives the sliding plate 311 to move out of the label outlet position of the labeling machine 30, the first linear module 321 drives the rotating label mechanism 323 to move above the sliding plate 311 along the horizontal X direction. At this time, the first lifting unit 322 drives the rotating label mechanism 323 to descend and absorb the label on the sliding plate 311. Then, the first linear module 321 drives the rotating label mechanism 323 to move above the positioning fixture 20 along the horizontal X direction. Then, the first lifting unit 322 drives the rotating label mechanism 323 to descend, so that the rotating label mechanism 323 can attach the label to the copper bus 9. Since the positioning fixture 20 rotates with the rotating disk 22, when the positioning fixture 20 rotates to the workstation corresponding to the labeling device 3, the positioning fixture 20 is at a certain angle to the horizontal X axis or the horizontal Y axis. Therefore, when the rotating label mechanism 323 moves to the top of the positioning fixture 20, the rotating label mechanism 323 needs to rotate the label absorbed by itself by a certain angle to avoid the label being attached obliquely to the copper bus 9.

[0029] The first lifting unit 322 of the present embodiment uses a lifting cylinder; of course, in other embodiments, the first lifting unit 322 may also use an electric push rod, which is not limited here.

[0030] Reference Figure 6The rotating label mechanism 323 includes a second driving unit 3230, a buffer mechanism 3231 and a vacuum adsorption head 3232. The second driving unit 3230 is vertically fixed to the lifting end of the first lifting unit 322. The second driving unit 3230 is connected to the vacuum adsorption head 3232 for driving the vacuum adsorption head 3232 to rotate. The second driving unit 3230 is controlled by an industrial computer. The second driving unit 3230 uses a stepping motor. The second driving unit 3230 drives the vacuum adsorption head 3232 to rotate at any angle. The vacuum adsorption head 3232 is used to absorb the label on the sliding plate 311. A buffer mechanism 3231 is provided between the vacuum adsorption head 3232 and the second driving unit 3230. The buffer mechanism 3231 is used to buffer the force of the vacuum adsorption head 3232 acting on the label conveying mechanism 31 or the copper bar 9, so as to avoid hard contact between the vacuum adsorption head 3232 and the copper bar 9 or the sliding plate 311 on the label conveying mechanism 31, which is conducive to improving the service life of the vacuum adsorption head 3232. The second lifting unit 72 of this embodiment uses a lifting cylinder; of course, in other embodiments, the second lifting unit 72 may also use an electric push rod, which is not limited here.

[0031] Reference Figure 1 , Figure 3 and Figure 8 The label scanning unit 4 is controlled by the industrial computer and is arranged on the base 1. The label scanning unit 4 is used to scan and read the barcode or QR code information on the label attached by the labeling device 3 on the copper bus 9. Specifically, the label scanning unit 4 includes a support rod 40, a mounting rod 41 and a scanner 42. The support rod 40 is fixed on the fixed disk 10 vertically, the mounting rod 41 is fixed on the mounting rod 41 horizontally, and the scanner 42 is fixed on the mounting rod 41. Of course, the scanner 42 is electrically connected to the industrial computer. The scanner 42 is located above the rotating disk 22. When the positioning fixture 20 on the rotating disk 22 rotates to the bottom of the corresponding scanner 42, the scanner 42 scans and reads the barcode or QR code information on the label of the copper bus 9 fixed on the positioning fixture 20, so that the information of the label on the copper bus 9 is displayed on the industrial computer.

[0032] Reference Figure 1 , Figure 3 and Fig. 9The leak detection device 5 includes a supporting and fixing component 50 and a plurality of color sensors 51. The supporting and fixing component 50 is fixed on the fixed disk 10 vertically. In this embodiment, there are 4 color sensors 51 but it is not limited thereto. The 4 color sensors 51 can be fixed on the supporting and fixing component 50 in an array, and the 4 color sensors 51 are all located above the rotating disk 22. The plurality of color sensors are all connected to the industrial control machine. When the positioning fixture 20 on the rotating disk 22 rotates to the bottom of the corresponding color sensor 51, the color sensor 51 identifies whether there is a missing part on the copper bar 9 of the positioning fixture 20. For example, the copper bar 9 has a connector for connecting the copper bar 9 to other electrical components. Of course, the connector on the copper bar 9 faces upward, and the color of the connector is different from that of the copper bar 9. The color sensor 51 can identify whether the connector is missing on the copper bar 9, thereby achieving the purpose of leak detection. Of course, in other embodiments, the color sensor 51 can also be replaced by a CCD camera, which is not limited here.

[0033] According to Figure 1 , Figure 3 and Figure 10-12 The withstand voltage test device 6 is controlled by the industrial computer and is arranged on the base 1. The withstand voltage test device 6 includes a first withstand voltage test unit 60 and a second withstand voltage test unit 61. The first withstand voltage test unit 60 is used to test the withstand voltage of the copper bar 9 before applying pressure to the insulation layer of the copper bar 9, and the second withstand voltage test unit 61 is used to test the withstand voltage of the copper bar 9 after applying pressure to the insulation layer of the copper bar 9. Of course, the test data of the first withstand voltage test unit 60 and the second withstand voltage test unit 61 are associated with the information on the label attached to the copper bar 9 and displayed on the industrial computer. In this way, the test data of the copper bar 9 can be obtained by tracing the information on the label on the copper bar 9, so that the test data of the withstand voltage test of the copper bar 9 has a traceability function.

The connecting plate 6041 is fixed to the lifting end of the first lifting mechanism 603. The first probes 6042 are fixed on the connecting plate 6041. The two first probes 6042 are respectively electrically connected to the positive and negative poles of the test lead of the withstand voltage tester. When testing the insulation withstand voltage performance of the insulating layer between the copper conductor A90 and the copper conductor B91, the first lifting mechanism 603 drives the first probe mechanism 604 to descend, so that the two first probes 6042 are respectively in contact with the copper conductor A90 and the copper conductor B91, and the insulation withstand voltage performance of the insulating layer between the copper conductor A90 and the copper conductor B91 can be tested. After the first probe mechanism 604 is tested, the industrial computer controls the first drive unit 21 to drive the rotating disk 22 to rotate, so that the positioning fixture 20 rotates to the position corresponding to the second withstand voltage test unit 61. The copper conductor A90 and the copper conductor B91 are regarded as a whole and defined as the copper conductor A90B. The second withstand voltage test unit 61 is mainly used to test the insulation withstand voltage performance of the insulation layer between the copper conductor A90B and the copper conductor C92.

[0036] Reference Figure 1-Figure 3 and Figure 11-Figure 12The second withstand voltage test unit 61 includes a withstand voltage tester, a second support assembly 610, a second lifting mechanism 611, a second probe mechanism 612, a pressure block 6122, a pressure detection element 613, a third lifting mechanism 614 and a third probe mechanism 615. The withstand voltage tester of the second withstand voltage test unit 61 uses the withstand voltage tester of the first withstand voltage test unit 60, that is, the second withstand voltage test unit 61 and the first withstand voltage test unit 60 share a withstand voltage tester. The second probe mechanism 612 is located above the rotating disk 22, the third probe mechanism 615 is located below the rotating disk 22, the second support assembly 610 is vertically arranged on the base 1, the second lifting mechanism 611 uses a pressure electric cylinder 310, the second lifting mechanism 611 is vertically arranged on the base 1 and is drivingly connected to the second probe mechanism 612. The second probe mechanism 612 includes a fixing plate 6120 and at least two second probes 6121. The fixing plate 6120 is fixed to the lifting end of the second lifting mechanism 611. The second probes 6121 are vertically fixed on the fixing plate 6120. The two second probes 6121 are used to contact the copper conductor A90 and the copper conductor B91 respectively.

[0037] Reference Figure 1 , Fig.11 or Fig.12, the pressing block 6122 is fixed on the fixing plate 6120 of the second probe mechanism 612, and the distance between the pressing block 6122 and the positioning fixture 20 is smaller than the distance between the probe on the second probe mechanism 612 and the positioning fixture 20, so that when the second probe mechanism 612 descends and contacts the copper conductor A90, the pressing block 6122 first contacts the copper conductor A90, and applies pressure to the insulating layer between the copper conductor A90 and the copper conductor B91, and then the two second probes 6121 contact the copper conductor A90 and the copper conductor B91 respectively. Among them, the pressure detection element 613 is arranged between the lifting end of the second lifting mechanism 611 and the second probe mechanism 612, and the pressure detection element 613 uses a pressure sensor to detect the pressure of the pressing block 6122 pressing on the copper bar 9. When the positioning fixture 20 rotates to the bottom of the second probe mechanism 612, the second probe mechanism 612 descends to apply pressure to the insulating layer of the copper bar 9 and then tests the pressure resistance of the copper bar 9. The third lifting mechanism 614 uses an electric cylinder 310. The third lifting mechanism 614 is arranged on the base 1 and is connected to the third probe mechanism 615. The positioning fixture 20 is provided with a perforation 201 that penetrates the opposite surface of itself. The rotating disk 22 is provided with an avoidance groove 220 at a position corresponding to the perforation 201. The probe of the third probe mechanism 615 can pass through the avoidance groove 220 and the perforation 201 in sequence to contact the copper conductor C92 of the copper bus 9 on the positioning fixture 20. As a test scenario, when testing the insulation withstand voltage performance of the insulating layer between the copper conductor A90B and the copper conductor C92, the positioning fixture 20 rotates to the bottom of the second probe mechanism 612. While the second lifting mechanism 611 drives the second probe mechanism 612 to descend, the third lifting mechanism 614 drives the third probe mechanism 615 to rise. In this way, the pressure block 6122 on the second probe mechanism 612 first contacts the copper conductor A90, and after applying pressure to the insulating layer between the copper conductor A90 and the copper conductor B91, refer to Fig.12 , the two second probes 6121 on the opposite sides of the pressing block 6122 are in contact with the copper conductor A90 and the copper conductor B91 respectively, and the probe of the third probe mechanism 615 (the third probe 6150) is in contact with the copper conductor C92. Since the two second probes 6121 on the second probe mechanism 612 that are in contact with the copper conductor A90 and the copper conductor B91 respectively are both electrically connected to the positive electrode of the test line of the withstand voltage tester, and the probe of the third probe mechanism 615 (the third probe 6150) is electrically connected to the negative electrode of the test line, the insulation withstand voltage performance of the insulation layer between the copper conductor A90B and the copper conductor C92 can be tested.

[0038] As another test scenario, after applying pressure to the insulating layer between copper conductor A90 and copper conductor B91, the insulation withstand voltage of the insulating layer between copper conductor A90 and copper conductor B91 is tested. When the positioning fixture 20 rotates to the bottom of the second probe mechanism 612, the second probe mechanism 612 descends, and the pressing block 6122 on the second probe mechanism 612 first contacts the copper conductor A90. After applying pressure to the insulating layer between copper conductor A90 and copper conductor B91, the two second probes 6121 on the second probe mechanism 612 contact the copper conductor A90 and copper conductor B91 respectively, and the two second probes 6121 on the second probe mechanism 612 are also electrically connected to the positive and negative poles of the test line of the withstand voltage tester respectively. In this way, the second probe mechanism 612 can apply pressure to the insulating layer between copper conductor A90 and copper conductor B91, and then test the insulation withstand voltage performance of the insulating layer between copper conductor A90 and copper conductor B91.

[0039] When the copper busbar 9 is tested by the withstand voltage test device 6 , the positioning fixture 20 on the rotating disk 22 rotates to the unloading station 103 on the corresponding base 1 , and then the tested copper busbar 9 is placed on the conveying system 8 by the picking device 7 and output by the conveying system 8 .

[0040] Reference Figure 1 or Figure 2 or Figure 3 The conveying system 8 is controlled by the industrial computer and is arranged on the base 1. The conveying system 8 includes a first conveying device 80 and a second conveying device 81. The first conveying device 80 and the second conveying device 81 both use existing conveyor belt devices, which are not described here. The first conveying device 80 is used to output the copper bars 9 that have passed the test, and the second conveying device 81 is used to output the copper bars 9 that have failed the test. The conveying direction of the first conveying device 80 is along the horizontal Y direction, and the second conveying device 81 is along the horizontal X direction.

[0041] Reference Figure 3 and Fig.13The material taking device 7 is controlled by the industrial computer and is arranged on the base 1, and is used to clamp the copper bar 9 on the positioning fixture 20 and after being tested by the pressure test device 6, and place the copper bar 9 that has passed the test on the first conveying device 80, or place the copper bar 9 that has failed the test on the second conveying device 81. Specifically, the material taking device 7 includes a third support assembly 70, a second linear module 71, a second lifting unit 72, a rotary power unit 73 and a pneumatic clamp 74. The third support assembly 70 is arranged on the base 1, the second linear module 71 is arranged on the third support assembly 70, the slider on the second linear module 71 is connected with a fixed seat 710, the second lifting unit 72 uses a cylinder or an electric push rod, the second lifting unit 72 is arranged on the fixed seat 710, the second lifting unit 72 is used to drive the pneumatic clamp 74 to move up and down, and the pneumatic clamp 74 is used to clamp the copper bar 9; the rotating power unit 73 uses a driving motor, the rotating power unit 73 is fixed on the lifting end of the second lifting unit 72, the rotating power unit 73 is connected to the pneumatic clamp 74, and is used to drive the pneumatic clamp 74 to rotate, and the rotating power unit 73 can make the pneumatic clamp 74 flexibly place the copper bar 9 on the first conveying device 80 or the second conveying device 81. Among them, the second linear module 71 drives the fixed seat 710 to drive the pneumatic clamp 74 to place the copper bar 9 that has passed the test on the first conveying device 80, or to place the copper bar 9 that has failed the test on the second conveying device 81. It can be understood that when the positioning fixture 20 on the rotating disk 22 rotates to the unloading station 103 on the corresponding base 1, the second linear module 71 drives the fixed seat 710 to drive the pneumatic clamp 74 to move to the top of the positioning fixture 20, and then drives the pneumatic clamp 74 to descend through the second lifting unit 72. At this time, the pneumatic clamp 74 grabs the copper bar 9 on the positioning fixture 20. When the industrial computer determines that the copper bar 9 is qualified after the test, the second linear module 71 is controlled to drive the fixed seat 710 to drive the pneumatic clamp 74 to place the copper bar 9 that has passed the test on the first conveying device 80, and the qualified copper bar 9 is output by the first conveying device 80; when the industrial computer determines that the copper bar 9 is unqualified after the test, the second linear module 71 is controlled to drive the fixed seat 710 to drive the pneumatic clamp 74 to place the copper bar 9 that has failed the test on the second conveying device 81, and the unqualified copper bar 9 is output by the second conveying device 81.

[0042] The working principle of the copper busbar withstand voltage test automation equipment of the present invention: When the copper busbar withstand voltage test automation equipment of the present invention is used, the copper busbar 9 to be tested is positioned on the positioning fixture 20, and the rotating disk 22 is driven to rotate by the first driving unit 21. When the positioning fixture 20 rotates to the station corresponding to the labeling device 3, the label is attached to the labeling position on the copper busbar 9 by the labeling device 3; after the labeling is completed, the rotating disk 22 is then driven to rotate by the first driving unit 21. When the positioning fixture 20 rotates to the station corresponding to the label scanning unit 4, the label information on the copper busbar 9 is scanned and read by the label scanning unit 4. The information of the label scanned and read by the label scanning unit 4 is displayed on the industrial computer; then the rotating disk 22 is driven to rotate by the first driving unit 21. When the positioning fixture 20 rotates to the station corresponding to the first withstand voltage test unit 60, the withstand voltage of the copper busbar 9 is tested by the first withstand voltage test unit 60 before applying pressure to the insulating layer of the copper busbar 9; then the rotating disk 22 is driven to rotate by the first driving unit 21. When the positioning fixture 20 rotates to the station corresponding to the second withstand voltage test unit 60, the copper busbar 9 is tested for withstand voltage before applying pressure to the insulating layer of the copper busbar 9. When the positioning fixture 20 is at the workstation of the test unit 61, the second withstand voltage test unit 61 applies pressure to the insulation layer of the copper busbar 9 and tests the withstand voltage of the copper busbar 9. The test data of the first withstand voltage test unit 60 and the second withstand voltage test unit 61 are associated with the information on the label of the copper busbar 9 and displayed on the industrial computer. The test data of the copper busbar 9 can be obtained by tracing the information on the label, so that the test data has a traceability function; after the withstand voltage test is completed, the first driving unit 21 continues to drive the rotating disk 22 to rotate. When the positioning fixture 20 rotates to the workstation corresponding to the material taking device 7, the copper busbar 9 on the positioning fixture 20 is clamped by the material taking device 7; when the industrial computer determines that the copper busbar 9 on the positioning fixture 20 is qualified, the material taking device 7 places the qualified copper busbar 9 on the first conveying device 80 and outputs it by the first conveying device 80; when the industrial computer determines that the copper busbar 9 on the positioning fixture 20 is unqualified, the material taking device 7 places the unqualified copper busbar 9 on the second conveying device 81 and outputs it by the second conveying device 81.

[0043] In summary, the present invention can test the pressure resistance of the copper bar 9 before applying pressure to the insulating layer of the copper bar 9, and can also test the pressure resistance of the copper bar 9 after applying pressure to the insulating layer of the copper bar 9. It can also make the pressure resistance test data of the copper bar 9 have a traceability function, and can realize the automated test of the pressure resistance of the copper bar 9, thereby effectively improving the pressure resistance test efficiency of the copper bar 9.
