Description

[0003] In the winding device, when the winding roller winds the copper foil, air will be trapped between the copper foil layers, causing gaps between the copper foils. Gaps will prevent the foil from being wound tightly, which will cause the foil to be loose, called loose winding. At the same time, since the state of the copper foil (such as thickness, humidity, surface treatment, etc.) may vary from production batch to production batch, there may be a certain error in the line speed. Therefore, when the line speed decreases, a gap is likely to appear between the copper foil and the winding roller; when the line speed of the copper foil increases, the copper foil is prone to breakage.

[0018] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention. Example

[0019] like Figure 1-Figure 3As shown, the present invention provides a standard copper foil surface treatment machine, including: an unwinding device 11, a tank treatment unit 12, a drying device 13, and a winding device 14, which are arranged in sequence, wherein the tank treatment unit 12 includes a pickling tank 121, a pickling tank 2 122, a roughening tank 1 123, a curing tank 1 124, a roughening tank 2 125, a curing tank 2 126, a roughening tank 3 127, a curing tank 3 128, a washing tank 1 129, a blackening tank 1210, a washing tank 2 1211, an ashing tank 1212, a washing tank 3 1213, a passivation tank 1214, a washing tank 4 1215, a washing tank 5 1216, and a silane tank 1217. , wherein the winding device 14 comprises a base 1, fixed frames 2 are installed on both sides of the base 1, a winding roller bearing seat 21 and a supporting roller bearing seat 22 are installed on the top of the fixed frame 2 in sequence, and a winding roller 3 and a supporting roller 4 are installed respectively through the winding roller bearing seat 21 and the supporting roller bearing seat 22, a clamping roller 5 is installed on the top of the supporting roller 4 of the fixed frame 2, a driving motor 23 for driving the winding roller 3 to rotate is installed on the fixed frame 2, a reducer 24 is installed between the driving motor 23 and the winding roller 3 of the fixed frame 2, a tensioning mechanism 6 is installed on the opposite sides of the two fixed frames 2, and a tracking roller mechanism 7 is installed between the two fixed frames 2 and the winding roller 3 and the supporting roller 4; like Fig.13 As shown, three guide rollers are arranged in the tank body of the tank body processing unit 12: an inlet roller, a submerged roller, and an outlet roller. The rotation of the three guide rollers is driven by a servo motor reducer through a synchronous belt.

[0020] The material of the feed roller (conductive roller) is a stainless steel sprayed Hastelloy roller; the material of the outlet roller and the submersible roller is SUS316L, and the submersible roller is coated with hard rubber.

[0021] The tank body in the tank body treatment unit 12 is equipped with liquid inlet and liquid discharge pipes, and the tank body is equipped with liquid inlet pipes so that the liquid can flow smoothly. Each liquid tank is equipped with an anode plate, which is installed in parallel with the copper foil, with a pole distance of 62±0.5mm. The side of the anode plate facing the copper foil is coated with DSA. On both sides of the anode plate, the liquid tank is also equipped with a shielding device that can adjust the shielding amount. The anode plate outlet position is perpendicular to the tank body for easy connection; the distance between the anode plate and the copper foil surface can be adjusted, and the bottom of the tank body has a slope for convenient liquid and sewage discharge.

[0022] A total of 8 conductive rollers are arranged on the liquid tank (the maximum current of the first 6 rollers is 6KA, and the maximum current of the last 2 rollers is 3KA). The roller surface material of the 6 conductive rollers is stainless steel sprayed Hastelloy. All conductive rollers have cooling water channels, and are equipped with conductive copper rings and conductive oil-type conductive devices at both ends. The rated current of the 6 conductive devices can reach 6KA.

[0023] A squeezing roller with a compression method is installed above each guide roller to squeeze out the liquid on the copper foil. The squeezing roller above the conductive roller is an adjustable spring compression type, and the rest are self-weight compression types, and the adjustable spring compression type is pneumatically controlled.

[0024] The functions of the pickling tank 1 121 and the pickling tank 2 122 are to remove the oxide layer on the surface of the rough foil (copper foil before treatment). The pickling tank 1 121 preliminarily removes the oxide layer on the surface of the copper foil.

[0025] A pre-pickling tank is set at the pickling tank 121 and the pickling tank 2 122, with two sprays for each smooth surface and rough surface. After pickling, a transition tank is set between each liquid tank, and each transition tank is equipped with four spray pipes. Each spray pipe cleans the front and back sides of the copper foil. The water hole size is 1.8mm, the rough hole distance is 20mm, and the smooth hole distance is 30mm. All spray pipes imitate the three-ship model for easy disassembly.

[0026] The main functions of the roughening groove 123, the roughening groove 2 125 and the roughening groove 3 127 are to increase the roughness of the surface of the copper foil, thereby improving the adhesion and stability of the copper foil to other materials.

[0027] The curing tank 1 124 , the curing tank 2 126 , and the curing tank 3 128 are used to perform curing treatment on the copper foil to make the treatment layer on the surface of the copper foil more solid.

[0028] Water washing tank 1 129, water washing tank 2 1211, water washing tank 3 1213, water washing tank 4 1215 and water washing tank 5 1216 are used to clean the electrolyte and other impurities attached to the surface of the copper foil. After the copper foil is treated with pickling and roughening, some chemical substances will remain on the surface. The water washing tank removes these residues by flushing with clean water to ensure the cleanliness of the copper foil surface. They are all equipped with liquid inlet and liquid discharge pipes. The water inlet distributor is made of 316L. The liquid inlet pipe is connected to eight ball valves. There are eight spray pipes in the tank. Each spray pipe is equipped with a stainless steel nozzle to clean the front and back of the copper foil.

[0029] The blackening tank 1210 is mainly used to perform blackening treatment on the copper foil. After the blackening treatment, a special oxide film is formed on the surface of the copper foil, which can enhance the bonding force between the copper foil and materials such as resin and improve the use effect of the copper foil in the multi-layer PCB board.

[0030] The ashing tank 1212 is mainly used to perform galvanizing treatment on the copper foil to form a barrier layer, which can improve the anti-oxidation ability of the copper foil in natural air and also help to improve the bonding strength between the copper foil and materials such as resin.

[0031] The passivation tank 1214 is used to perform passivation treatment on the copper foil, that is, to form a dense oxide film on the surface of the copper foil to improve the oxidation resistance and heat resistance of the copper foil.

[0032] The silane tank 1217 is provided with a spraying device, which can coat the silane coupling agent on both sides of the copper foil.

[0033] The reducers 24 and the drive shafts of the unwinding device 11 and the rewinding device 14 are connected via synchronous belts; the frames of the unwinding device 14 and the rewinding device 11 have an integral deviation adjustment function.

[0034] The bearing seat 21 of the winding roller of the winding device 14 and the bearing seat of the unwinding roller of the unwinding device 11 also have the function of adjusting the deviation.

[0035] The middle roller system consists of an active roller and a passive roller. The active roller is driven by a motor reducer via a synchronous belt, and the passive roller is driven by a flat belt and a pulley. The advantage of the flat belt is that it can slip moderately according to the different states of the foil surface to compensate for the error of the linear speed and avoid slippage between the roller shaft and the copper foil. Slippage between the roller shaft and the copper foil will cause scratches on the foil surface.

[0036] In the drying device 13, there is an exhaust hood at the oven inlet to exhaust water vapor; there is a wind knife at the oven outlet to blow cold air to cool the foil surface; a flattening roller, also called an arc roller or a stretching roller, is arranged behind the wind knife to prevent the folded foil from being affected by tension and gathering in the middle to cause folding.

[0037] like Figure 3 As shown, one end of the copper foil is fixed on the winding roller 3, and the winding roller 3 is driven to rotate by the driving motor 23 to realize the winding of the copper foil. The other end of the copper foil passes between the supporting roller 4 and the clamping roller 5. The supporting roller 4 is made of rubber. The supporting roller 4 provides support and protection for the copper foil to prevent the copper foil from being scratched. At the same time, the copper foil is clamped by cooperating with the clamping roller 5 to provide tension for the copper foil winding, so as to avoid gaps between the copper foil winding layers, resulting in loose rolls. like Fig.12 As shown, the tracking roller mechanism 7 includes two limit seats 71 fixedly connected to the two fixing frames 2, a tracking roller 72 is arranged between the two limit seats 71, a circular arc groove 73 is opened in the limit seat 71, and the tracking roller 72 includes a rotating shaft 74 arranged at both ends of the tracking roller 72, and the rotating shaft 74 is located in the circular arc groove 73; Two sliders 75 are slidably connected at both ends of the rotating shaft 74 in the circular arc groove 73 , and a spring 76 is installed between the opposite sides of the two sliders 75 and the circular arc groove 73 .

[0038] The two sliders 75 are slidably connected to opposite sides thereof with balls 77 , and the two balls 77 are respectively located at two ends of the rotating shaft 74 .

[0039] The copper foil moves from the supporting roller 4 to the tracking roller 72 and is then wound on the winding roller 3. The sliders 75 on both sides of the rotating shaft 74 in the arc groove 73 stably clamp the tracking roller 72 through the elastic force of the springs 1 76 on both sides. When the springs 1 76 on both sides are not subjected to external force, the tracking roller 72 is tangent to the winding roller 3. Therefore, when there is no copper foil on the winding roller 3, the tracking roller 72 can still remain tangent to the winding roller 3 and stably stationary. When the copper foil wound on the winding roller 3 is thicker, the copper foil on the surface of the winding roller 3 squeezes the tracking roller 72, causing it to move upward along the arc groove 73, thereby increasing the distance between it and the winding roller 3. At the same time, the spring 1 76 on one side of the rotating shaft 74 is squeezed and the other side is stretched, so that the tracking roller 72 always keeps in contact with the copper foil on the winding roller 3, and the elastic force of the spring 1 76 causes the tracking roller 72 to always apply pressure to the copper foil, so that the copper foil is wound on the winding roller 3 without a gap, thereby avoiding the phenomenon of loose winding.

[0040] It should be noted that the rotating shaft 74 is clamped by the balls 77 to reduce the frictional resistance to the rotating shaft 74, so that the tracking roller 72 and the copper foil rotate synchronously.

[0041] A section of the copper foil is clamped by the support roller 4 and the clamping roller 5, and a section of the copper foil close to the winding roller 3 is clamped by the tracking roller 72, so that the copper foil is always kept in a taut state during winding, so that the copper foil can be tightly wound on the winding roller 3.

[0042] like Figure 3-Figure 6 As shown, a cylinder 25 is installed on the opposite side of the two fixing frames 2, and a support plate 26 is fixedly connected to the output end of the cylinder 25. A clamping roller bearing seat 27 is installed on the top of the support plate 26, and both ends of the clamping roller 5 are rotatably connected to the clamping roller bearing seat 27.

[0043] The height of the support plate 26 and the clamping roller bearing seat 27 are changed by the cylinder 25, and the height of the clamping roller 5 is adjusted so that the gap between it and the support roller 4 is adapted to the thickness of the copper foil.

[0044] like Figure 4 , Figure 6 , Figure 7 As shown, the tensioning mechanism 6 includes a fixed plate 61 fixedly connected to the fixed frame 2 at the support roller bearing seat 22, two tensioning roller bearing seats 62 are slidably connected to the top of the fixed plate 61, and the two tensioning roller bearing seats 62 are respectively located on both sides of the support roller bearing seat 22, and the fixed plate 61 is rotatably connected with a tensioning roller 63 between the two tensioning roller bearing seats 62 arranged on one side of the support roller 4; The tensioning mechanism 6 also includes a tensioning wheel 64 fixedly connected to both ends of the supporting roller 4 and a pressure-blocking plate 65 arranged above and below the tensioning wheel 64. Two rotating rods 66 are rotatably connected to both ends of the tensioning roller 63. The two rotating rods 66 are rotatably connected to two pressure-blocking plates 65 arranged above and below, respectively. The two tensioning rollers 63 are connected by two sets of rotating rods 66 and pressure-blocking plates 65, and the rotating rods 66, the pressure-blocking plates 65 and the tensioning rollers 63 are all rotationally connected. When the distance between the two tensioning roller bearing seats 62 increases, the angle of the two rotating rods 66 on the tensioning roller 63 becomes smaller, so that the two pressure-blocking plates 65 are closer to each other. When the distance between the two tensioning roller bearing seats 62 decreases, the angle of the two rotating rods 66 on the tensioning roller 63 becomes larger, so that the two pressure-blocking plates 65 are away from each other.

[0045] The tensioning wheels 64 at both ends of the support roller 4 are clamped by two pressure-blocking plates 65. The tensioning wheels 64 are made of elastic rubber. When the two pressure-blocking plates 65 approach each other, the friction between the pressure-blocking plates 65 and the tensioning wheels 64 is increased, thereby reducing the rotation speed of the tensioning wheels 64, that is, the rotation speed of the support roller 4, and then the support roller 4 slows down the transmission speed of the copper foil and further tightens the copper foil; conversely, when the two pressure-blocking plates 65 move away from each other, the support roller 4 reduces the tension on the copper foil; therefore, when the linear speed of the winding roller 3, that is, the copper foil, decreases, the copper foil can be kept in a taut state by increasing the tension on the copper foil, thereby avoiding the phenomenon of loosening of the copper foil due to the difference in linear speed; when the linear speed of the winding roller 3, that is, the copper foil, increases, the copper foil can be kept in a stable taut state by reducing the tension on the copper foil, thereby avoiding the phenomenon of broken foil due to the difference in linear speed.

[0046] like Figure 3-Figure 8 As shown, a threaded rod 67 is rotatably connected inside the fixed plate 61, the threads at both ends of the threaded rod 67 have opposite rotation directions, and the two ends of the threaded rod 67 are respectively threadedly connected to the two tensioning roller bearing seats 62, and one end of the threaded rod 67 close to the winding roller bearing seat 21 is fixedly connected to a connecting rod 68, the connecting rod 68 is rotatably connected to the fixed frame 2, and a gear 69 is fixedly connected to the outer side of the connecting rod 68.

[0047] The winding roller 3 includes a driving shaft 31 arranged at both ends of the winding roller 3 , the driving shaft 31 is rotatably connected to the winding roller bearing seat 21 , and the driving shaft 31 is connected to the reducer 24 .

[0048] like Figure 8-Figure 11 As shown, the tensioning mechanism 6 also includes a fixed seat 610 fixedly connected to the fixed frame 2 at the winding roller bearing seat 21, the driving shaft 31 passes through the winding roller bearing seat 21 and is rotatably connected to the fixed seat 610, a sleeve 611 is rotatably connected to one side of the fixed seat 610, a spiral guide groove 612 is opened on the surface of the sleeve 611, the driving shaft 31 is located in the sleeve 611, and a sliding ring 613 is slidably connected to the driving shaft 31, a limit pin 614 is fixedly connected to the outer side of the sliding ring 613, the limit pin 614 passes through the inner side of the spiral guide groove 612 and protrudes from the outside of the sleeve 611, and a flywheel 615 is fixedly arranged on the outer side of one end of the sleeve 611 close to the fixed seat 610.

[0049] A fixed block 616 is fixedly connected between the fixed frame 2 and the fixed seat 610, and a hollow groove 617 is opened in the fixed block 616, and a sliding seat 618 and a rack 619 are slidably connected through the hollow groove 617. The sliding seat 618 and the rack 619 are arranged up and down, and a sliding ring 620 is slidably connected to the end of the sliding seat 618 away from the rack 619. The sliding ring 620 is arranged on the outside of the sleeve 611, and the sliding ring 620 is fixedly connected to the limit pin 614, and the side of the rack 619 away from the sliding seat 618 is meshed with the gear 69.

[0050] A second spring 621 is installed between the two ends of the sliding seat 618 and the empty slot 617 , a third spring 622 is installed between the two ends of the rack 619 and the empty slot 617 , and a stopper 623 is fixedly connected to the top of the rack 619 on both sides of the sliding seat 618 .

[0051] The adjustment mechanism of the two tensioning roller bearing seats 62 is as follows: like Figure 7 , Figure 8-Figure 11 As shown, when the winding roller 3 rotates, the limit pin 614 on the driving shaft 31 pushes the sleeve 611 to rotate synchronously through the spiral guide groove 612, and at the same time drives the flywheel 615 at one end of the sleeve 611 to rotate. When the rotation speeds of the winding roller 3 and the driving shaft 31 change, the sleeve 611 can maintain the original rotation speed due to the inertia of the flywheel 615, so that a rotation speed difference is generated between the sleeve 611 and the driving shaft 31; when the rotation speed of the driving shaft 31 is greater than the rotation speed of the sleeve 611, the limit pin 614 and the sliding ring 613 on the driving shaft 31 are blocked by the spiral guide groove 612 on the sleeve 611 and move in one direction of the spiral guide groove 612, thereby driving the sliding ring 620 to move, so that the sliding seat 618 fixedly connected to the limit pin 614 slides in one direction in the fixed block 616 The sliding seat 618 moves in the direction of the stopper 623 and pushes the stopper 623 on the rack 619, so that the rack 619 moves to one side of the fixed block 616 and drives the gear 69 meshing with the rack 619 to rotate, thereby driving the connecting rod 68 to rotate, and causing the threaded rod 67 connected to the connecting rod 68 to rotate. Since the tensioning roller bearing seat 62 is threadedly connected to the threaded rod 67, the tensioning roller bearing seat 62 is driven to move when the threaded rod 67 rotates. Since the threads at both ends of the threaded rod 67 rotate in opposite directions, the two tensioning roller bearing seats 62 are moved away from each other, reducing the friction between the pressure-blocking plate 65 and the tensioning wheel 64, thereby reducing the pulling force of the support roller 4 and the clamping roller 5 on the copper foil. When the speed of the winding roller 3 becomes faster, the pulling force on the copper foil is reduced while the copper foil is still kept in a tensioned state.

[0052] When the rotation speed of the driving shaft 31 is less than the rotation speed of the sleeve 611, the limit pin 614 and the sliding ring 613 on the driving shaft 31 are pushed by the spiral guide groove 612 on the sleeve 611 and move in the other direction of the spiral guide groove 612, thereby driving the sliding ring 620 to move, so that the sliding seat 618 fixedly connected to the limit pin 614 slides in the other direction in the fixed block 616, pushing another stopper 623 on the rack 619, causing the threaded rod 67 to rotate in the opposite direction, thereby increasing the distance between the two tensioning rollers 63, increasing the friction between the pressure-blocking plate 65 and the tensioning wheel 64, and further increasing the pulling force of the support roller 4 and the clamping roller 5 on the copper foil. When the rotation speed of the winding roller 3 slows down, the pulling force on the copper foil is increased while the copper foil is still kept in a tensioned state.

[0053] After the speed of the winding roller 3 changes, the rotation speed of the flywheel 615 on the sleeve 611 gradually becomes the same as the rotation speed of the driving shaft 31, so that the limit pin 614 slowly resets. At the same time, under the push of the spring two 621 on both sides of the sliding seat 618, the sliding seat 618 gradually returns to its original position, so that the rack 619 is reset under the push of the spring three 622 on both sides, and then the pressure resistance plate 65 returns to its original position, thereby ensuring the stable rotation of multiple support rollers 4 again, and cooperating with the clamping roller 5 to tighten the copper foil.
