[0021] In one embodiment, please refer to Figures 1 to 4 As shown, the present invention provides a copper clad laminate withstand voltage insulation testing device, including a workbench 1, a withstand voltage insulation testing module 2, an appearance fixing module 3, a vertical moving module 4, and an appearance acquisition module 5.

[0022] The workbench 1, as the supporting base of the entire equipment, is a rectangular structure with a clear length and width direction, providing a spatial reference for the movement and positioning of each module.

[0023] The withstand voltage insulation test module 2 is fixedly connected to the workbench 1 and has a test base 6. The test base 6 is provided with a first test area 21 for placing the copper-clad laminate. The first test area 21 is provided with a flip bracket 7 that can rotate along the width direction of the workbench 1. Inside the flip bracket 7, a first insulation test component 8 is provided that abuts against one end face of the copper-clad laminate. The first test area 21 positions the copper-clad laminate for testing, and the flip bracket 7 fixes the copper-clad laminate. The first insulation test component 8 is electrically connected to an external high-voltage generator. The first insulation test component 8 has an upward-facing electrode test surface that maintains good contact with the lower end face of the copper-clad laminate placed on the flip bracket 7.

[0024] The appearance fixing module 3 is fixedly connected to the workbench 1 and has a second test area 31. The flipping bracket 7 can flip the copper-clad board on the first test area 21 to the second test area 31. The second test area 31 is used to position the copper-clad board after it is flipped and to provide stable support for appearance image acquisition.

[0025] The vertical moving module 4 is fixedly connected to the workbench 1 and has a vertically movable sliding base 41. The sliding base 41 can move towards or away from the test base 6, and its interior is provided with a second insulation test assembly 42 that abuts against the other end face of the copper-clad laminate. The second insulation test assembly 42 is connected to another external high-voltage generator and has a downward-facing test surface. When the sliding base 41 moves to the test position, the test surface of the second test electrode array presses against the upper end face of the copper-clad laminate located in the first test area 21.

[0026] The appearance acquisition module 5 is fixedly connected to the workbench 1 and has an appearance moving end 51 that can move along the length of the workbench 1. An image acquisition device 52 is fixed on the appearance moving end 51. The image acquisition device 52 can move above the first test area 21 or the second test area 31 to acquire images of the copper-clad laminate. The image acquisition device 52 is an industrial camera used to acquire surface images of the copper-clad laminate.

[0027] Workflow: Step 1: The operator or robot places the copper-clad laminate to be tested on the flip bracket 7 in the first test area 21, ensuring that its position is accurate; Step 2: The control system drives the appearance moving end 51 to move the image acquisition device 52 above the first test area 21 to acquire an image of the initial upper surface of the copper-clad board. After the acquisition is completed, the appearance moving end 51 moves and the image acquisition device 52 moves above the second test area 31. Step 3: The control system drives the vertical moving module 4 to lower the sliding base 41 to a predetermined height, and drives the sliding base 41 to move towards the test base 6, so that the electrode array of the second insulation test component 42 is in close contact with the upper surface of the copper-clad laminate. The high voltage generator of the second insulation test component 42 is started, and the insulation withstand voltage performance between the upper surface of the copper-clad laminate and the internal conductive layer is tested according to the preset program. After the test is completed, the second insulation test component 42 is reset. Step 4: The operation of the withstand voltage insulation test module 2 drives the flip bracket 7 and the copper-clad plate on it to rotate 180 degrees. After flipping, the original lower surface of the copper-clad plate becomes upward and is transferred to the second test area 31 of the appearance fixing module 3. Step 5: Image acquisition device 52 acquires an image of the initial upper surface of the copper-clad laminate. After the test is completed, the copper-clad laminate is removed.

[0028] Specifically, this example achieves integrated continuous testing of the double-sided insulation withstand voltage performance and double-sided appearance quality of the same copper clad laminate sample through the collaborative design of the withstand voltage insulation test module 2, appearance fixing module 3, vertical movement module 4 and appearance acquisition module 5. This reduces the movement and waiting time during the copper clad laminate testing process and improves the testing efficiency and production cycle of the copper clad laminate.

[0029] In an optional example, please refer to Figures 1 to 4 As shown, the first test area 21 is provided with a length positioning block 9 and a width positioning block 10 that are fixed to the test base 6 by bolt connection. The length positioning block 9 is set along the length direction of the worktable 1, and the width positioning block 10 is set along the width direction of the worktable 1. The first test area 21 is provided with a width clamping block 11 that can reciprocate along the width direction of the worktable 1 and a length clamping block 12 that can reciprocate along the length direction of the worktable 1. The width clamping block 11 and the width positioning block 10 are set opposite to each other and are used to clamp the two sides of the copper-clad laminate along the width direction of the worktable 1. The length clamping block 12 and the length positioning block 9 are set opposite to each other and are used to clamp the two sides of the copper-clad laminate along the length direction of the worktable 1. The length positioning block 9 and the width positioning block 10 together form a right-angle reference for initial positioning of the adjacent sides of the copper-clad laminate. The length positioning block 9, the width positioning block 10, the width clamping block 11, and the length clamping block 12 are all made of insulating materials, such as insulating plastic. When it is necessary to fix the copper-clad laminate, the copper-clad laminate is placed in the first test area 21, so that its adjacent two sides are respectively close to the length positioning block 9 and the width positioning block 10. The width clamping block 11 moves towards the width positioning block 10 to press the copper-clad laminate from the other side. At the same time, the length clamping block 12 moves towards the length positioning block 9 to press the copper-clad laminate from the other end to complete the fixation. After all tests are completed, the two sets of clamping blocks move in opposite directions to release the copper-clad laminate, making it easy to flip or remove.

[0030] Specifically, this example achieves rapid positioning and fixing of the insulating board through the cooperation of the length positioning block 9, the width positioning block 10, the width clamping block 11 and the length clamping block 12, ensuring accurate contact between the test electrodes of the first insulation test component 8 and the second insulation test component 42 and the copper-clad laminate, thereby improving the detection accuracy of the withstand voltage insulation test module 2.

[0031] In an optional example, please refer to Figures 1 to 5 As shown, the upper end of the test base 6 is provided with a positioning end face 61, and a downwardly extending flipping groove 62 is formed on the positioning end face 61. The flipping bracket 7 is provided with an adsorption end face 71. The flipping bracket 7 can be rotatably inserted into the flipping groove 62, so that the positioning end face 61 and the adsorption end face 71 are on the same horizontal plane and are combined to form the first test area 21. The flipping bracket 7 is provided with a detection through groove 72 that extends through the flipping bracket 7 along the height direction of the flipping bracket 7. The first insulation test component 8 can pass through the detection through groove 72 and abut against one end face of the copper-clad laminate. The test base 6 can be made of insulating material, such as insulating plastic.

[0032] Specifically, this example ensures the stability of the copper-clad laminate placement by designing the positioning end face 61 and the adsorption end face 71 as a test plane, avoids stress concentration caused by unevenness of the copper-clad laminate, ensures the precise contact between the test electrodes of the first insulation test component 8 and the second insulation test component 42 and the copper-clad laminate, and improves the detection accuracy of the withstand voltage insulation test module 2.

[0033] In an optional example, please refer to Figures 1 to 5 As shown, the test base 6 is provided with a first support part 63 and a second support part 64. The flipping bracket 7 is fixed with a first rotating shaft 13 and a second rotating shaft 14. The first rotating shaft 13 is rotatably connected to the first support part 63 and extends out of the first support part 63. A driven gear 15 is fixedly fitted on the outer wall of the first rotating shaft 13 by a key connection. A sliding rack 16 is slidably mounted on the test base 6 and meshes with the driven gear 15. A flipping telescopic cylinder 17 is fixed on the test base 6 by bolt connection. The telescopic end of the flipping telescopic cylinder 17 is fixedly connected to the sliding rack 16 by bolt connection. The second rotating shaft 14 is rotatably connected to the second support part 64. Among them, a rack groove located outside the first test area 21 is opened on the test base 6 along the length direction of the workbench 1, and the sliding rack 16 is slidably inserted into the rack groove.

[0034] Specifically, in this example, the operation of the flip telescopic cylinder 17 drives the movement of the sliding rack 16, causing the driven gear 15 to rotate, which in turn drives the flip bracket 7 to complete the flipping action, thus ensuring the stability of the copper-clad laminate during rotation.

[0035] In an optional example, please refer to Figures 1 to 6 As shown, a flipping negative pressure channel 701 is provided inside the flipping bracket 7. Several sets of first negative pressure holes 711 are opened on the adsorption end face 71, and the first negative pressure holes 711 are connected to the flipping negative pressure channel 701. A shaft flow channel 141 is opened inside the second rotating shaft 14. The shaft flow channel 141 has several side wall holes 142 opened on the outer wall of the second rotating shaft 14, and the side wall holes 142 are connected to the flipping negative pressure channel 701. The end of the shaft flow channel 141 extends to the end of the second rotating shaft 14 facing away from the flipping bracket 7. The second rotating shaft 14 is connected to an external negative pressure device through a rotary joint. The negative pressure device is used to provide negative pressure. The first negative pressure holes 711 form an adsorption area and directly contact the back of the copper-clad laminate being adsorbed.

[0036] Specifically, this example avoids the problems of entanglement, pulling, wear or interference that may occur when the external hose is rotated at high speed by completely embedding the negative pressure flow channel inside the rotating shaft and the bracket body. This enables high-speed, large-angle, and repetitive mechanical rotation of the copper-clad laminate, ensuring the service life of the withstand voltage insulation test equipment.

[0037] In an optional example, please refer to Figures 1 to 8 As shown, the flip bracket 7 includes a first flip layer 73 and a second flip layer 74 that are fixedly connected to each other.

[0038] The first flip layer 73 is provided with a first lug 731 and a second lug 732, and the second flip layer 74 is provided with a first lug 741 and a second lug 742. The first lug 731 and the first lug 741 are combined to form a first support part 63. The first lug 731 has a first ear hole 733 that penetrates the first lug 731, and the first lug 741 has a second ear hole 743 that penetrates the first lug 741. The first ear hole 733 and the second ear hole 743 are connected and used to fix the first rotating shaft 13. The second lug 732 and the second lug 742 are combined to form a second support part 64. The end of the flip layer 74 facing the first flip layer 73 is provided with a flow channel groove 746. The second support ear 732 is provided with a support ear groove 734, and the second support ear 742 is provided with a support ear groove 744. A third ear hole 745 is opened in the second support ear 744, penetrating the second support ear 742. The flow channel groove 746 is connected to the first support ear groove 734 and the second support ear groove 744, and together they form a flip negative pressure flow channel 701 with a cavity structure. The second rotating shaft 14 passes through the third ear hole 745 and is fixed in the first support ear groove 734. The side wall hole 142 is provided in the space between the first support ear groove 734 and the second support ear groove 744.

[0039] In an optional example, the first flip layer 73 and the second flip layer 74 may be manufactured by stamping and fixed by welding, and their surfaces may be coated with insulating materials, such as insulating plastic, insulating rubber, etc.

[0040] In another alternative example, the first flip layer 73 and the second flip layer 74 can be made of insulating hard plastic and fixed to each other by adhesive or hot melting. A sealing ring or sealant can be provided between the mating surfaces to ensure that the flip negative pressure flow channel 701 formed by the combination has good airtightness.

[0041] Specifically, this example effectively reduces the manufacturing difficulty and cost of the flip bracket 7 by splitting the flip bracket 7 into a first flip layer 73 and a second flip layer 74.

[0042] In an optional example, please refer to Figures 1 to 9As shown, the test base 6 has a first sliding groove 65 at the end facing the appearance fixing module 3. The length clamping block 12 is inserted into the first sliding groove 65 by sliding. The lower part of the test base 6 is fixed with a length telescopic cylinder 66 by bolt connection. The upper end of the worktable 1 has a working through groove 101 that runs vertically through the worktable 1. The length clamping block 12 has a downward extending extension block 121. The extension block 121 passes through the working through groove 101 and is fixedly connected to the telescopic end of the length telescopic cylinder 66 by bolt connection.

[0043] Specifically, in this example, the length telescopic cylinder 66 is arranged below the workbench 1, so that there is no interference above the workbench 1 surface of the first test area 21, ensuring the flatness of the test plate, avoiding bumps during the movement of the copper-clad board, and ensuring the surface quality of the copper-clad board. At the same time, the length clamping block 12 cooperates with the first slide groove 65 through a plug-in method, which has extremely high resistance to torsion and lateral force, preventing the clamping block from tilting or shaking when subjected to clamping reaction force.

[0044] In an optional example, please refer to Figures 1 to 10 As shown, the test base 6 has a second sliding groove 67 on its side wall. The width clamping block 11 is slidably inserted into the second sliding groove 67. A side end plate 18 is fixed to the side wall of the test base 6 by bolts. A side motor 19 is fixed to the side end plate 18 by bolts. A side lead screw 20 is rotatably installed in the second sliding groove 67. The output shaft of the side motor 19 is driven by the side lead screw 20. The width clamping block 11 has a drive threaded hole 111. The side lead screw 20 is threadedly inserted into the drive threaded hole 111. One end of the side lead screw 20 is installed in the second sliding groove 67 by bearing connection, and the other end of the side lead screw 20 is connected to the side end plate 18 by bearing connection.

[0045] Specifically, this example achieves precise driving of the width clamping block 11 through the cooperation of the side motor 19 and the side lead screw 20, ensuring the accurate positioning of the copper-clad laminate and improving the clamping efficiency of the copper-clad laminate.

[0046] In an optional example, please refer to Figures 1 to 12 As shown, the vertical moving module 4 includes a vertical base 44 fixedly connected to the worktable 1 by bolts, a vertical guide rod 45 fixedly connected to the sliding base 41 by bolts, a vertical guide ring 46 fixedly connected to the vertical base 44 by bolts, the vertical guide rod 45 being slidably inserted into the vertical guide ring 46, and a vertical telescopic cylinder 43 fixedly connected to the vertical base 44 by bolts, the telescopic end of the vertical telescopic cylinder 43 being fixedly connected to the sliding base 41 by bolts.

[0047] The appearance acquisition module 5 includes an appearance base 53 fixedly connected to the workbench 1 by bolts. A length guide rail 54, extending along the length of the workbench 1, is fixedly mounted between the appearance base 53 and the vertical base 44 by bolts. The appearance moving end 51 includes a moving bracket, on which guide wheels 55 are fixedly mounted by bolts. The guide wheels 55 are slidably mounted on the length guide rail 54. A drive pulley 56 is mounted on the appearance base 53 by bearings. A driven pulley 57 is mounted on the vertical base 44 by bearings. A power belt 58 is installed between the drive pulley 56 and the driven pulley 57, and the power belt 58 is fixedly connected to the moving bracket by bolts. An appearance motor 59 is fixedly mounted on the appearance base 53 by bolts, and the output shaft of the appearance motor 59 is connected to the drive pulley 56 by a key. When the sliding base 41 is at its initial height, the length guide rail 54 is positioned below the sliding base 41.

[0048] Specifically, this example uses the insertion and engagement of the vertical guide rod 45 and the vertical guide ring 46 to form a high-rigidity structure that can withstand the huge reaction force generated when the second insulation test component 42 presses the copper-clad laminate, ensuring the stability of the copper-clad laminate during testing and guaranteeing the testing accuracy of the copper-clad laminate. At the same time, through the cooperation of the length guide rail 54, the drive pulley 56 and the driven pulley 57, interference with the vertical movement path of the sliding base 41 is avoided, realizing the rapid switching of the image acquisition unit 52 between the first test area 21 and the second test area 31.

[0049] In an optional example, please refer to Figures 1 to 12 As shown, the appearance fixing module 3 includes a negative pressure fixing plate that is fixedly connected to the workbench 1 by bolts. A negative pressure fixing channel 32 is provided inside the negative pressure fixing plate. The second test area 31 is located at the upper end of the negative pressure fixing plate. Several sets of second negative pressure holes 33 are provided inside the second test area 31. All the second negative pressure holes 33 are connected to the negative pressure fixing channel 32.

[0050] Specifically, this example uses a negative pressure fixing plate to achieve stable adsorption of the copper-clad laminate, ensuring the detection accuracy of the copper-clad laminate in the second test area 31 and improving the detection efficiency of the copper-clad laminate in the second test area 31.

[0051] In summary, this invention, through the collaborative design of the withstand voltage insulation test module 2, the appearance fixing module 3, the vertical movement module 4, and the appearance acquisition module 5, achieves integrated continuous testing of the double-sided insulation withstand voltage performance and double-sided appearance quality of the same copper-clad laminate sample. This reduces the movement and waiting time during the copper-clad laminate testing process, improving the testing efficiency and production cycle of the copper-clad laminate. Simultaneously, by designing the positioning end face 61 and the adsorption end face 71 as a single test plane, the stability of the copper-clad laminate placement is ensured, avoiding stress concentration caused by unevenness. This guarantees precise contact between the test electrodes of the first insulation test component 8 and the second insulation test component 42 and the copper-clad laminate, improving the testing accuracy of the withstand voltage insulation test module 2. Furthermore, by completely integrating the negative pressure flow channel within the rotating shaft and the support body, potential problems such as entanglement, pulling, wear, or interference of the external hose during high-speed rotation are avoided. This enables high-speed, large-angle, and repetitive mechanical rotation of the copper-clad laminate, ensuring the service life of the withstand voltage insulation testing equipment.
