[0019] 2. The present invention uses the connecting plate and the buffer silica gel sleeve to press the copper foil, and reduces the pressure of the connecting plate on the copper foil through the buffer silica gel sleeve. At the same time, the contact area between the buffer silica gel sleeve and the copper foil is reduced through the reserved groove, thereby reducing the contact friction between the copper foil and the buffer silica gel sleeve, ensuring that the buffer silica gel sleeve fits and slides on the surface of the copper foil when the connecting plate moves without tearing the copper foil;

[0020] 3. The present invention places the copper foil unfolded and tightened by the flattening plates on the surface of the arc-shaped table. Subsequently, the buffer strip is placed in the middle of the arc-shaped table and pressed. Then, the buffer strip is pulled to slide on the surface of the arc-shaped table to smooth the copper foil in a direction perpendicular to the unfolding direction, ensuring that there are no wrinkles on the surface of the copper foil. At the same time, the part of the copper foil exceeding the edge of the arc-shaped table is cut during the smoothing operation, ensuring the size of the copper foil and the quality after surface processing.

Specific embodiments

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0031] The lifting hydraulic rod (model number YQ22-10), telescopic electric push rod (model number ZWMD0023), adjusting motor (model number 5IK60RGN-CF), and rotating motor (model number 6IK180W-200W) mentioned in the present invention can all be obtained by purchasing from the market or customizing privately.

[0032] As Figure 1 and Figure 2 shown, for a copper foil manufacturing surface processing equipment, two groups of symmetric lifting hydraulic rods 3 are fixed on the upper surface of the fixed seat 1. The tops of the two symmetric lifting hydraulic rods 3 are fixed with a support cross beam 11. In the middle of the upper surface of the support cross beam 11, a lifting support block 4 is fixed. A rotating support shaft 7 is rotatably inserted through the middle of the lifting support block 4. One end of the rotating support shaft 7 is fixed with a rotating frame 10. The other end of the rotating support shaft 7 is provided with a rotating motor 8. The bottom of the rotating motor 8 is provided with a support plate 9. One end of the support plate 9 is fixed to the lifting support block 4.

[0033] As Figure 1 , Figure 5 and Figure 6As shown in the figure, two flattening components 5 are installed between two rotating frames 10 and are symmetrically distributed. The flattening component 5 includes two fixing plates 501. The two fixing plates 501 are respectively fixed to the two rotating frames 10. A double-headed lead screw 502 is rotatably installed between the two ends of the fixing plate 501. Two symmetrically distributed adjusting sliders 503 are sleeved on the outer side of the double-headed lead screw 502. The adjusting slider 503 is in threaded transmission with the double-headed lead screw 502. A telescopic electric push rod 504 is fixed to the outer side of the adjusting slider 503. A flattening plate 505 is installed at the movable end of the telescopic electric push rod 504. A lead screw gear 508 is fixed at the middle of the double-headed lead screw 502. An adjusting gear 507 is meshed and connected to the outer side of the lead screw gear 508. One end of the adjusting gear 507 is connected to an adjusting motor 506. The adjusting motor 506 is fixedly connected to the fixing plate 501. The telescopic electric push rod 504 is used to push the flattening plate 505 to move to clamp the naturally drooping copper foil from the middle. Then, the adjusting motor 506 drives the double-headed lead screw 502 to rotate through the adjusting gear 507 and the lead screw gear 508, so that the two adjusting sliders 503 drive the two upper and lower adjacent telescopic electric push rods 504 and the flattening plates 505 to move away from each other, and the naturally drooping copper foil is straightened to avoid wrinkles on the copper foil.

[0034] As Figure 7 shown, the flattening plate 505 includes a connecting plate 5051. A buffer silica gel sleeve 5052 is sleeved on the outer side of the connecting plate 5051. The movable end of the telescopic electric push rod 504 penetrates through the buffer silica gel sleeve 5052 and is fixed to the connecting plate 5051. A reserved groove 5053 is provided on the surface of the buffer silica gel sleeve 5052. The thickness of the buffer silica gel sleeve 5052 is 0.5 - 1 cm. The connecting plate 5051 and the buffer silica gel sleeve 5052 are used to press the copper foil, and the pressure of the connecting plate 5051 on the copper foil is reduced through the buffer silica gel sleeve 5052. At the same time, the contact area between the buffer silica gel sleeve 5052 and the copper foil is reduced through the reserved groove 5053, so as to reduce the contact friction between the copper foil and the buffer silica gel sleeve 5052, and ensure that the buffer silica gel sleeve 5052 slides along the surface of the copper foil when the connecting plate 5051 moves and does not tear the copper foil.

[0035] As Figure 1 and Figure 4 shown, an operating table 2 is installed between two groups of lifting hydraulic rods 3. The operating table 2 includes a column 201. The bottom end of the column 201 is fixed to the fixed seat 1. The top end of the column 201 is fixed with a placing table 202. An arc-shaped tabletop 203 is provided on the upper surface of the placing table 202. The edge of the arc-shaped tabletop 203 is an arc surface. The placing table 202 with the arc-shaped tabletop 203 is used to place the flattened and tightened copper foil, and then the copper foil is smoothed from the middle of the arc-shaped tabletop 203 to both sides to ensure that the copper foil is completely unfolded and there are no wrinkles on the surface, and to ensure the quality of the copper foil after surface processing.

[0036] AsFigure 1 and Figure 3 As shown in Figure 3 , an auxiliary flattening plate 6 is placed on the surface of the arc-shaped tabletop 203. The auxiliary flattening plate 6 includes a hand-held plate 601. The length dimension of the hand-held plate 601 is the same as the width dimension of the placement table 202. A buffer strip 602 is installed below the hand-held plate 601. A positioning card slot is provided on the upper surface of the buffer strip 602. The bottom end of the hand-held plate 601 is clamped in the positioning card slot and is adhesively connected to the buffer strip 602 through glue. The bottom end of the buffer strip 602 has two symmetrical inclined surfaces, and the two inclined surfaces form a V shape. The connection at the bottom edge of the two inclined surfaces is an arc surface. The elastic buffer strip 602 installed at the bottom of the hand-held plate 601 is used to flatten the copper foil placed on the surface of the arc-shaped tabletop 203, and the copper foil will not be damaged during flattening.

[0037] Cutting blades 603 are detachably installed at both ends of the hand-held plate 601. The bottom end of the cutting blade 603 is a V-shaped blade. A fastening screw 604 is inserted through the top end of the cutting blade 603. The threaded end of the fastening screw 604 is screwed into the end part of the hand-held plate 601. With the cutting blades 603 detachably installed at the end part of the hand-held plate 601, when the buffer strip 602 flattens the copper foil, the part of the copper foil that extends beyond the edge of the adjusting slider 503 is cut to ensure the product size of the copper foil.

[0038] Working principle: First, let the copper foil naturally drop between the four flattening plates 505, and then turn on the power of the device. After the power is turned on, the telescopic electric push rod 504 drives the flattening plates 505 to approach the copper foil until the four flattening plates 505 clamp the copper foil from the middle of the copper foil. At this time, the telescopic electric push rod 504 drives the flattening plates 505 to retreat slightly to ensure that the flattening plates 505 unfold and tighten the copper foil when moving and will not tear the copper foil. Subsequently, the adjusting motor 506 is powered on and starts to drive the double-headed lead screw 502 to rotate through the adjusting gear 507 and the lead screw gear 508. At this time, the double-headed lead screw 502 drives the two adjusting sliders 503 to move towards both ends of the double-headed lead screw 502 through the threaded transmission with the adjusting sliders 503. The adjusting sliders 503 drive the telescopic electric push rod 504 and the flattening plates 505 to move. At this time, the two adjacent flattening plates 505 move away from each other, and the flattening plates 505 moving away unfold and tighten the copper foil;

[0039] After the copper foil is unfolded and tightened by the flattening plates 505, the rotating motor 8 is powered on and starts to drive the rotating support shaft 7 and the rotating frame 10 to rotate. At this time, the rotating support shaft 7 drives the rotating frame 10 to rotate by ninety degrees, so that the unfolded and tightened copper foil is parallel to the placement table 202. The lifting hydraulic rod 3 starts and drives the lifting support block 4 to move downward. The lifting support block 4 drives the flattening plates 505 and the copper foil unfolded and tightened by the flattening plates 505 to move downward simultaneously through the rotating support shaft 7, the rotating frame 10 and the fixed plate 501 until the copper foil contacts the arc-shaped tabletop 203;

[0040] Next, the staff presses the buffer strip 602 at the bottom of the handheld plate 601 against the middle of the arc-shaped tabletop 203 and pulls the buffer strip 602 to slide on the surface of the arc-shaped tabletop 203, so that the buffer strip 602 slides from the middle of the arc-shaped tabletop 203 to one side. During this process, the buffer strip 602 smooths the unfolded and tightened copper foil. While smoothing, the part of the copper foil that extends beyond the edge of the arc-shaped tabletop 203 is cut with the cutting blade 603 to control the size of the copper foil. The buffer strip 602 is used to smooth the copper foil and fit it on the surface of the arc-shaped tabletop 203. Finally, surface treatment operations such as tin spraying, immersion gold, and immersion silver are performed on the copper foil on the surface of the arc-shaped tabletop 203, and the copper foil is fully unfolded and smoothed to ensure that there are no wrinkles on the surface of the copper foil and no omissions on the surface of the copper foil during surface treatment, ensuring the quality of the copper foil after surface treatment.

[0041] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
