Description

Technical Field

[0001] The present invention relates to the technical field of aluminum-based copper clad laminate processing, and particularly to a surface leveling device for processing aluminum-based copper clad laminates. Background Art

[0002] Aluminum-based copper clad laminates, as the core substrate materials in the manufacturing of printed circuit boards, play a crucial role. During the processing of aluminum-based copper clad laminates, it is necessary to level the aluminum-based copper clad laminates so that the surface is flat without affecting subsequent use.

[0003] A Chinese patent with the publication number CN114850994B discloses a surface leveling device for processing aluminum-based copper clad laminates, including a working platform. One side of the upper surface of the working platform is provided with a support frame, and a support table is installed on the upper surface of the working platform near the support frame. A power roller is installed in the middle of the support frame, and several horizontal rollers are arranged side by side directly below the power roller at the bottom of the support frame. A laser scanner for detecting surface protrusions of the aluminum-based copper clad laminate is installed at the top of the support frame. Above the support table, there is a support plate. Support columns for maintaining stability are provided at the four corners of the support plate. A first lead screw slide is embedded in the middle of the support plate. A second lead screw slide is installed on the slider of the first lead screw slide, and a hydraulic rod is installed on the slider of the second lead screw slide. Although the above patent can level the aluminum-based copper clad laminate, due to the inconsistent concavo-convex degree of the aluminum-based copper clad laminate, if a rigid leveling roller is directly used to apply force forcibly, it may not only cause excessive indentations or damages on the surface of the plate, but also result in poor leveling effect due to uneven stress.

[0004] The present invention aims to solve the problems existing in the above patent. Therefore, a surface leveling device for processing aluminum-based copper clad laminates is proposed, which can gradually increase the pressing force to level the aluminum-based copper clad laminate, so as to ensure the safety of leveling and improve the leveling effect. Summary of the Invention

[0005] In order to overcome the disadvantages that due to the inconsistent concavo-convex degree of the aluminum-based copper clad laminate, if a rigid leveling roller is directly used to apply force forcibly, it may not only cause excessive indentations or damages on the surface of the plate, but also result in poor leveling effect due to uneven stress, the present invention provides a surface leveling device for processing aluminum-based copper clad laminates, which can gradually increase the pressing force to level the aluminum-based copper clad laminate, so as to ensure the safety of leveling and improve the leveling effect.

[0006] The present invention is realized through the following technical solutions: A surface leveling device for processing aluminum-based copper clad laminates, comprising a workbench and placing tables symmetrically fixed on the workbench. An electric roller is rotatably connected to the placing table. A fixed frame is fixedly connected to the top of the workbench, and a conveying roller is installed on the fixed frame. An electric lifting seat is installed between the two sides of the fixed frame. It further includes a leveling roller I rotatably passing through the electric lifting seat. The leveling roller I corresponds to the conveying roller. Sliders are slidably passed through both sides of the electric lifting seat. A leveling roller II corresponding to the conveying roller is rotatably passed through between the corresponding sliders. Sliding frames corresponding to the sliders are slidably passed through the electric lifting seat at equal intervals. Connecting springs are symmetrically connected between the sliding frames and the sliders. Electric screw rods threadedly connected to the sliding frames are installed at equal intervals on the top of the electric lifting seat. The electric screw rods are used to drive the sliding frames to move downward, and the sliding frames press on the connecting springs to adjust the force for pressing and leveling the leveling roller II, so that the leveling roller II gradually levels the aluminum-based copper clad laminate. A driving component is arranged on the electric lifting seat for driving the leveling roller I and the leveling roller II to rotate.

[0007] Further description, the driving component includes a rotating shaft rotatably connected to the electric lifting seat. The rotating shaft is located on the right side of the leveling roller I. A connecting rod is rotatably connected between the end of the rotating shaft and the end of the leveling roller II for driving the leveling roller II to rotate. Worms are fixedly sleeved on both the leveling roller I and the rotating shaft. An electric worm is installed on the electric lifting seat and meshes with the worm.

[0008] Further description, it further includes a heating component. The heating component includes spiral tubes fixedly passing through the leveling roller I and the leveling roller II. The outer wall of the spiral tube contacts the inner walls of the leveling roller I and the leveling roller II. Circular shells are rotatably sleeved on the first to the third spiral tubes from the right. Collection hoppers are fixedly passed through both the leveling roller I and the leveling roller II. Guide liquid pipes are rotatably connected to the ends of the first to the third collection hoppers from the right. The tail ends of the guide liquid pipes are connected and communicated with the adjacent circular shells. A heating box is installed on the top of the workbench. A drain pipe is connected to the heating box, and the tail end of the drain pipe is connected to the bottom of the rightmost circular shell. A liquid inlet pipe is connected to the top of the heating box, and the tail end of the liquid inlet pipe is connected to the end of the leftmost collection hopper. A water inlet component is arranged between the guide liquid pipe and the heating box for discharging cold water into the guide liquid pipe.

[0009] Further description, the water inlet component includes a four-way pipe connected to the top of the heating box. The tail end of the four-way pipe is connected to the guide liquid pipe for discharging cold water into the guide liquid pipe. An electric control valve is installed on the four-way pipe. Temperature detectors are installed at equal intervals on the inner side of the electric lifting seat. The temperature detectors are arranged staggeredly with the leveling roller II. The temperature detectors and the electric control valve are electrically connected through a control module.

[0010] Further description, the surface leveling device for processing aluminum-based copper clad laminates further includes a detection component. The detection component includes an n-shaped plate fixedly connected to the top of one of the placement tables. Digital height gauges are symmetrically and fixedly inserted through the n-shaped plate for detecting the flatness of the surface of the aluminum-based copper clad laminate. An L-shaped rod is fixedly connected to the probe of the digital height gauge. Movable blocks are slidably inserted through both sides of the n-shaped plate. A cross bar that contacts the inner side of the L-shaped rod is fixedly connected between the movable blocks for limiting the L-shaped rod. A return spring is connected between the movable block and the n-shaped plate. A trigger component is arranged between the movable block and one of the placement tables for driving the movable block to move. A conveying component is arranged between the placement table and the workbench for driving the aluminum-based copper clad laminate to move.

[0011] Further description, the trigger component includes a rack fixedly connected to the movable block. A rotating rod is rotatably inserted through one of the placement tables. A gear meshing with the rack is fixedly sleeved at the end of the rotating rod. Contact blocks are fixedly sleeved at equal intervals on the rotating rod.

[0012] Further description, the conveying component includes an electric frame arranged between the placement table and the workbench. Driving rollers are rotatably connected at equal intervals on the electric frame to drive the aluminum-based copper clad laminate to move for re-leveling. An electric conveyor is installed on the workbench for driving the aluminum-based copper clad laminate to move.

[0013] Further description, the surface leveling device for processing aluminum-based copper clad laminates further includes fixing blocks symmetrically and fixedly connected between the electric lifting seat and the fixed frame. A brush roller is rotatably connected between the corresponding fixing blocks for removing impurities on the aluminum-based copper clad laminate.

[0014] The beneficial effects of the present invention are as follows: 1. By starting the electric screw rod to drive the sliding frame to move downward, the sliding frame compresses the connecting spring. The greater the degree of compression of the connecting spring, the greater the pressure exerted by the leveling roller II. After adjusting the pressure exerted by the three leveling rollers II to gradually increase from right to left, the aluminum-based copper clad laminate can be made to contact the leveling roller II and the leveling roller I in sequence from right to left for leveling. In this way, by adjusting the pressure exerted by the leveling roller II, the pressure applied can be gradually increased to level the aluminum-based copper clad laminate, preventing damage to the aluminum-based copper clad laminate caused by forcibly applying a large force, ensuring the safety of leveling, and thus improving the leveling effect.

[0015] 2. Under the action of the detection component, whenever the leveled aluminum-based copper clad laminate moves to the left, the digital height gauge can detect the flatness of the surface of the aluminum-based copper clad laminate, making the unqualified aluminum-based copper clad laminate leveled again, preventing the incomplete leveling of the surface of the aluminum-based copper clad laminate from affecting subsequent use, and thus ensuring the leveling effect of the aluminum-based copper clad laminate.

[0016] 3. Under the action of the brush roller, every time the aluminum-based copper clad laminate moves to the left, the brush roller can remove the impurities on the aluminum-based copper clad laminate. After the impurities are removed, the aluminum-based copper clad laminate continues to move to the left and is leveled, which can prevent the leveling failure caused by impurities adhering to the aluminum-based copper clad laminate, thereby further ensuring the smooth leveling of the aluminum-based copper clad laminate.

Detailed implementation manners

[0029] Example: A surface leveling device for processing aluminum-based copper clad laminates. Please refer to Figures 1 - 7 As shown, it includes a workbench 1 and placing tables 2 symmetrically and fixedly connected to the top of the workbench 1 on the left and right. The placing table 2 can be used to place the aluminum-based copper clad laminate. Three electric rollers 21 are rotatably connected to the placing table 2. A fixing frame 3 is fixedly connected to the middle of the top of the workbench 1. A conveying roller 5 is installed on the fixing frame 3. An electric lifting seat 4 is installed between the front and rear sides of the fixing frame 3. It also includes a leveling roller I 6, a slider 7, a leveling roller II 8, a sliding frame 9, a connecting spring 10, an electric screw 11 and a driving assembly. The leveling roller I 6 is rotatably inserted through the left side of the electric lifting seat 4. The leveling roller I 6 corresponds to the conveying roller 5. Sliders 7 are slidably inserted through the lower parts of the front and rear sides of the electric lifting seat 4. A leveling roller II 8 is rotatably inserted between the corresponding sliders 7 on the front and rear sides. The leveling roller II 8 corresponds to the conveying roller 5. Three sliding frames 9 are slidably inserted through the upper part of the electric lifting seat 4 at equal intervals. The three sliding frames 9 respectively correspond to the three sliders 7. Connecting springs 10 are symmetrically connected between the bottom of the sliding frame 9 and the top of the slider 7. Three electric screws 11 are evenly installed at the middle of the top of the electric lifting seat 4. The three electric screws 11 are respectively threadedly connected to the upper parts of the three sliding frames 9. The electric screw 11 is used to drive the sliding frame 9 to move downward. The sliding frame 9 presses on the connecting spring 10 to adjust the force for pressing and leveling the leveling roller II 8, so that the leveling roller II 8 gradually levels the aluminum-based copper clad laminate. A driving assembly is arranged on the electric lifting seat 4. When the driving assembly operates, the driving assembly can drive the leveling roller I 6 and the leveling roller II 8 to rotate.

[0030] Please refer to Figure 3 and Figure 4As shown in the figure, the driving component includes a rotating shaft 12, an electric worm 121, a worm wheel 122 and a connecting rod 123. There are three rotating shafts 12 rotatably connected to the front side of the electric lifting seat 4. The rotating shafts 12 are located on the right side of the leveling roller I 6. There is a connecting rod 123 rotatably connected between the rear ends of the three rotating shafts 12 and the front ends of the three leveling rollers II 8. The connecting rod 123 can drive the leveling roller II 8 to rotate. Worm wheels 122 are fixedly sleeved on the front sides of both the leveling roller I 6 and the rotating shaft 12. An electric worm 121 is transversely installed on the front side of the electric lifting seat 4. The electric worm 121 meshes with the four worm wheels 122.

[0031] Please refer to Figures 5 - 7 As shown in the figure, it further includes a heating component arranged between the leveling roller I 6 and the leveling roller II 8. The heating component includes a spiral tube 13, a collecting hopper 131, a heating box 132, a liquid inlet pipe 133, a liquid discharge pipe 134, a circular shell 135, a liquid guide pipe 136 and a water inlet component. Spiral tubes 13 are fixedly inserted through the rear sides of both the leveling roller I 6 and the leveling roller II 8. The outer wall of the spiral tube 13 is in contact with the inner walls of the leveling roller I 6 and the leveling roller II 8. Circular shells 135 are rotatably sleeved on the rear sides of the first to the third spiral tubes 13 from the right. Collecting hoppers 131 are fixedly inserted through the middle parts of the rear sides of both the leveling roller I 6 and the leveling roller II 8. The rear ends of the first to the third collecting hoppers 131 from the right are rotatably connected to a liquid guide pipe 136. The tail end of the liquid guide pipe 136 is connected and communicated with the adjacent circular shell 135. A heating box 132 is installed on the rear side of the top of the workbench 1. The right side of the top of the heating box 132 is connected to a liquid discharge pipe 134. The tail end of the liquid discharge pipe 134 is connected to the bottom of the rightmost circular shell 135. The left side of the top of the heating box 132 is connected to a liquid inlet pipe 133. The tail end of the liquid inlet pipe 133 is connected to the rear end of the leftmost collecting hopper 131. A water inlet component is arranged between the liquid guide pipe 136 and the heating box 132. When the water inlet component operates, the water inlet component can discharge cold water into the liquid guide pipe 136. The water inlet component includes a four-way pipe 137, an electric control valve 138 and a temperature detector 139. The right side of the top of the heating box 132 is connected to a four-way pipe 137. The three tail ends of the four-way pipe 137 are respectively connected to the three liquid guide pipes 136. The four-way pipe 137 can discharge cold water into the liquid guide pipe 136. Electric control valves 138 are installed at the three tails of the four-way pipe 137. Three temperature detectors 139 are evenly spaced and installed on the rear side of the inner top of the electric lifting seat 4. The three temperature detectors 139 are staggered with the three leveling rollers II 8. The temperature detector 139 and the electric control valve 138 are electrically connected through a control module.

[0032] Initially, the four-way pipe 137 is externally connected to cold water, and the cold water is discharged into the four-way pipe 137. First, start the electric screw 11 according to the situation of the aluminum-based copper clad laminate. The forward rotation of the electric screw 11 drives the sliding frame 9 to move downward. The downward movement of the sliding frame 9 compresses the connecting spring 10. The greater the compression degree of the connecting spring 10, the greater the pressure exerted by the flattening roller II 8. After the compression degree of the connecting spring 10 is adjusted, turn off the electric screw 11. In this way, the compression degrees of the three groups of connecting springs 10 can be adjusted, and the compression degrees of the connecting springs 10 gradually increase from right to left, that is, the pressing forces of the three flattening rollers II 8 gradually increase from right to left. After the pressing forces of the three flattening rollers II 8 are adjusted, start the reverse rotation of the electric roller 21 and the conveying roller 5, and then start the rotation of the electric worm 121. The electric worm 121 drives the worm wheel 122 to rotate. The leftmost worm wheel 122 drives the flattening roller I 6 to rotate forward, and the remaining worm wheels 122 drive the rotating shaft 12 to rotate forward. The rotating shaft 12 drives the flattening roller II 8 to rotate forward through the connecting rod 123. At the same time, start the heating box 132 to heat the water into hot water, and the heating box 132 discharges the hot water into the drain pipe 134. The hot water in the drain pipe 134 is discharged into the spiral pipe 13 through the rightmost circular shell 135. The spiral pipe 13 discharges the water into the rightmost flattening roller II 8. The hot water heats the rightmost flattening roller II 8. As the hot water flows, the hot water in the rightmost flattening roller II 8 is discharged into the rightmost liquid collecting hopper 131 and then into the rightmost liquid guiding pipe 136. The rightmost liquid guiding pipe 136 discharges the hot water into the next circular shell 135. The hot water in the next circular shell 135 is discharged into the corresponding spiral pipe 13, so that the next flattening roller II 8 is heated. Repeating this way, the flattening roller II 8 and the flattening roller II 8 can be heated. The hot water in the flattening roller II 8 is discharged into the liquid inlet pipe 133 through the leftmost liquid collecting hopper 131, and the hot water in the liquid inlet pipe 133 is discharged back into the heating box 132 for continuous use, so that the hot water is continuously recycled. Then the operator places the aluminum-based copper clad laminate on the right placing table 2 from the right side. The aluminum-based copper clad laminate contacts the right electric roller 21. The reverse rotation of the right electric roller 21 drives the aluminum-based copper clad laminate to move leftward. The aluminum-based copper clad laminate moves leftward to between the flattening roller II 8 and the conveying roller 5. The reverse rotation of the conveying roller 5 and the forward rotation of the flattening roller II 8 drive the aluminum-based copper clad laminate to move leftward. The aluminum-based copper clad laminate contacts the three flattening rollers II 8 in sequence from right to left. Since the pressing forces of the three flattening rollers II 8 gradually increase from right to left, the three flattening rollers II 8 flatten the aluminum-based copper clad laminate from the smallest pressing force to the largest pressing force, making the surface of the aluminum-based copper clad laminate flat. As the aluminum-based copper clad laminate continues to move leftward and contacts the flattening roller I 6, the cooperation between the flattening roller I 6 and the conveying roller 5 performs the final flattening of the aluminum-based copper clad laminate. At the same time, since the flattening roller II 8 and the flattening roller II 8 are heated, the flattening roller II 8 and the flattening roller I 6 can better flatten the aluminum-based copper clad laminate through high temperature. The high temperature makes the plasticity of the aluminum-based copper clad laminate stronger, further improving the flattening effect. At the same time, start the temperature detector 139,The temperature detector 139 detects the temperature of the aluminum-based copper clad laminate during leveling. When the temperature of the aluminum-based copper clad laminate is relatively high, the temperature detector 139 controls the corresponding electric control valve 138 to start through the control module. When the electric control valve 138 starts, the cold water in the four-way pipe 137 is discharged into the liquid guide pipe 136. The cold water discharged mixes with the hot water in the liquid guide pipe 136, which causes the temperature of the hot water to drop. The hot water with the reduced temperature is discharged into the leveling roller II 8 for use. Repeating this process can gradually cool down the hot water. When the temperature detector 139 detects that the temperature of the aluminum-based copper clad laminate is at the normal temperature, the temperature detector 139 controls the electric control valve 138 to close through the control module, and the cold water stops being discharged into the liquid guide pipe 136. When the leveled aluminum-based copper clad laminate continues to move leftward and contacts the left electric roller 21, the left electric roller 21 rotates in reverse to drive the aluminum-based copper clad laminate to move leftward for conveying and collecting. Repeating this process can continuously level the aluminum-based copper clad laminate. Moreover, by adjusting the pressing force on the leveling roller II 8, the pressing force can be gradually increased to level the aluminum-based copper clad laminate, preventing damage to the aluminum-based copper clad laminate caused by applying too much force forcibly, so as to ensure the safety of leveling and improve the leveling effect. When all the aluminum-based copper clad laminates are leveled, the conveying roller 5 and the electric roller 21 are turned off. At the same time, the heating box 132 and the electric worm 121 are turned off. The electric worm 121 stops driving the worm gear 122 to rotate. The leveling roller I 6 and the leveling roller II 8 stop rotating forward. The hot water stops being discharged into the drain pipe 134, and the hot water also stops being discharged into the leveling roller II 8 and the leveling roller I 6, and then the subsequent processing of the leveled aluminum-based copper clad laminate can be carried out.,

[0033] Please refer to Figures 8 - 10As shown in the figure, the surface leveling device for processing aluminum-based copper clad laminates further includes a detection component installed between the workbench 1 and the placement table 2. The detection component includes an n-shaped plate 14, a digital display height gauge 141, a trigger component, a movable block 146, a conveying component, an L-shaped rod 149, a cross bar 1410, and a return spring 1411. On the right side of the top of the left placement table 2, an n-shaped plate 14 is fixedly connected. The digital display height gauges 141 are symmetrically and fixedly inserted through the front and back of the top of the n-shaped plate 14. The digital display height gauge 141 can detect the flatness of the surface of the aluminum-based copper clad laminate. On the lower left side of the probes of the digital display height gauges 141 on both the front and back sides, L-shaped rods 149 are fixedly connected. On both the front and back sides of the n-shaped plate 14, movable blocks 146 are slidably inserted. A cross bar 1410 is fixedly connected between the movable blocks 146 on both the front and back sides. The cross bar 1410 contacts the inner sides of the L-shaped rods 149 on both the front and back sides. The cross bar 1410 can limit the L-shaped rods 149. A return spring 1411 is connected between the bottom of the movable block 146 and the inner side of the n-shaped plate 14. A trigger component is arranged between the movable block 146 and the left placement table 2. When the trigger component operates, the trigger component can drive the movable block 146 to move downward. A conveying component is arranged between the placement table 2 and the workbench 1. When the conveying component operates, the conveying component can drive the aluminum-based copper clad laminate to move; The trigger component includes a rotating rod 142, a contact block 143, a gear 144, and a rack 145. On the right side of the bottom of the movable blocks 146 on both the front and back sides, racks 145 are fixedly connected. On the right side of the left placement table 2, a rotating rod 142 is rotatably inserted. On both the front and back ends of the rotating rod 142, gears 144 are fixedly sleeved. The gears 144 on both the front and back sides are respectively meshed with the racks 145 on both the front and back sides. Four contact blocks 143 are fixedly sleeved on the rotating rod 142 at equal intervals; The conveying component includes an electric frame 147, a driving roller 148, and an electric conveyor 1481. Electric frames 147 are arranged between the left and right placement tables 2 and the workbench 1. Three driving rollers 148 are rotatably connected at equal intervals on the upper part of the electric frame 147. When the driving roller 148 rotates, the driving roller 148 can drive the aluminum-based copper clad laminate to move for re-leveling. An electric conveyor 1481 is installed in the middle of the bottom of the workbench 1. The electric conveyor 1481 can drive the aluminum-based copper clad laminate to move to the right.

[0034] When the leveled aluminum-based copper clad laminate moves leftward and contacts the contact block 143, the aluminum-based copper clad laminate drives the contact block 143 to swing leftward. The leftward swing of the contact block 143 drives the rotating rod 142 to reverse. The reverse rotation of the rotating rod 142 drives the gear 144 to reverse. The reverse rotation of the gear 144 drives the rack 145 to move downward. The downward movement of the rack 145 drives the movable block 146 to move downward, compressing the return spring 1411. The downward movement of the movable block 146 drives the cross bar 1410 to move downward. The downward movement of the cross bar 1410 stops limiting the probe of the digital display height gauge 141. The probe of the digital display height gauge 141 moves downward and contacts the top of the leftward moving aluminum-based copper clad laminate. The digital display height gauge 141 detects the flatness of the surface of the aluminum-based copper clad laminate. When the surface of the aluminum-based copper clad laminate is not completely leveled, the data detected by the digital display height gauge 141 changes significantly. Thus, when the incompletely leveled aluminum-based copper clad laminate moves leftward and is on the left driving roller 148, the aluminum-based copper clad laminate disengages from the contact block 143. Due to the action of the return spring 1411, the movable block 146 moves upward to reset, driving the cross bar 1410 to move upward to reset. The cross bar 1410 drives the probe of the digital display height gauge 141 to move upward to reset through the L-shaped rod 149. Start the electric frame 147 to move downward, driving the driving roller 148 to move downward. The downward movement of the left driving roller 148 drives the aluminum-based copper clad laminate to move downward. When the driving roller 148 and the electric conveyor 1481 are at the same horizontal height, turn off the electric frame 147, and the driving roller 148 stops moving downward. The left driving roller 148 stops driving the aluminum-based copper clad laminate to move downward. At this time, start the left and right driving rollers 148 and the electric conveyor 1481 to rotate forward. The forward rotation of the left driving roller 148 drives the aluminum-based copper clad laminate to move rightward and contact the electric conveyor 1481. The forward rotation of the electric conveyor 1481 drives the aluminum-based copper clad laminate to move rightward for conveying. The aluminum-based copper clad laminate moves rightward and disengages from the left driving roller 148. The aluminum-based copper clad laminate continues to move rightward and contacts the right driving roller 148. The forward rotation of the right driving roller 148 drives the aluminum-based copper clad laminate to move rightward and be on the right electric frame 147. Turn off the left and right driving rollers 148 and the electric conveyor 1481, and then start the electric frame 147 to drive the driving roller 148 to move upward to reset. The right driving roller 148 drives the aluminum-based copper clad laminate to move upward to reset. Then start the right driving roller 148 to reverse, driving the aluminum-based copper clad laminate to move leftward and contact the conveying roller 5 and the leveling roller II 8 to be leveled again. In this way, it can prevent the incomplete leveling of the surface of the aluminum-based copper clad laminate from affecting subsequent use, thereby ensuring the leveling effect of the aluminum-based copper clad laminate.

[0035] Please refer to Figure 11As shown in the figure, the surface leveling device for processing aluminum-based copper clad laminates further includes a fixing block 15 and a brush roller 16. Fixing blocks 15 are fixedly connected to the lower part of the right side of the electric lifting seat 4 and the upper part of the right side of the fixing frame 3 symmetrically in the front and back. A brush roller 16 is rotatably connected between the corresponding fixing blocks 15 on the front and back sides. When the aluminum-based copper clad laminate moves and contacts the brush roller 16, the brush roller 16 can remove the impurities on the aluminum-based copper clad laminate.

[0036] When the aluminum-based copper clad laminate moves leftward and contacts the brush roller 16, the aluminum-based copper clad laminate drives the brush roller 16 to rotate. The rotation of the brush roller 16 can remove the impurities on the aluminum-based copper clad laminate. The aluminum-based copper clad laminate after removing the impurities continues to move leftward and is leveled. When the aluminum-based copper clad laminate moves leftward and disengages from the brush roller 16, the brush roller 16 stops rotating. In this way, it can prevent the aluminum-based copper clad laminate from being attached with impurities and causing the leveling to fail, thereby further ensuring that the aluminum-based copper clad laminate is smoothly leveled.
