[0008] Preferably, a winding roller is provided on the inner side of the mounting frame, and quadrangular prisms are inlaid on both ends of the winding roller. One end of the quadrangular prism is installed on one side of the mounting plate through a bearing, and the other end of the quadrangular prism rotates through the mounting frame and is fixedly connected to the driving end of the motor. The motor is installed on one side of the mounting frame.

[0009] Preferably, the mounting plate is threadedly connected to an upper portion of one side of the mounting frame, a square hole is formed between the mounting plate and the mounting frame, a limiting column is embedded in the square hole, and hexagonal holes are evenly distributed on one side of the mounting plate away from the quadrangular column.

[0010] Preferably, one side of the upper surface of the base is connected to a mounting seat via an electric push rod, and the electric push rod is arranged on both sides of the bottom end of the mounting seat.

[0011] Preferably, the upper middle portion of the detection rod is arranged in a U shape and the U-shaped protrusion faces the slide groove.

[0012] Preferably, the top block extends in the through slot and becomes shorter from top to bottom with equal length, one end of the top block is aligned in the slide slot and the top block is connected to the inner wall of the slide slot through spring 2, the spring 2 becomes shorter from top to bottom with equal length, and a counting switch is provided on the inner wall of the slide slot on the side of the spring 2 facing the top block, and the counting switch and the top block correspond one to one.

[0013] Preferably, one side of the bottom end of the detection rod is connected to the lower side wall of the through slot through a spring.

[0014] A method for using a roll copper foil packaging device comprises the following steps:

[0015] Step 1, put the two ends of the winding roller on the two ends of the quadrangular prism, then screw the mounting plate into the mounting frame, after the mounting plate is screwed in, insert the limit pin into the mounting plate and the mounting frame to fix the mounting plate and the mounting frame, the copper foil passes between roller one and roller two, then the copper foil is wound on the winding roller, the mounting frame is slid on the slide bar, the mounting frame is positioned in the groove, and compressed air is introduced into each limiting tube through the air pipe. At this time, the pressure of the gas introduced into the limiting tube by the air pipe on one side of the mounting frame is consistent, and the pressure of the gas introduced into the limiting tube by the air pipe on the other side of the mounting frame is consistent. After compressed air is introduced into the limiting tube, the pressure parameter can be read intuitively from the pressure gauge, and after compressed air of different pressures is introduced into the limiting tube, the slide rod slides in the limiting tube through the rubber plug;

[0016] Step 2: The motor uses the quadrangular prism to realize the winding roller winding the copper foil. During winding, the slide bar slides in the limit tube due to air pressure through the rubber plug. If the winding of the copper foil causes the winding roller to be subjected to excessive tension, the air pressure inside the limit tube changes, the mounting frame slides on the slide bar, and the gas squeezes the rubber sleeve inside the slide bar to deform it. The gas in the slide bar flows through the air holes to realize the deformation of the rubber sleeve, thereby achieving good winding of the copper foil.

[0017] The present invention provides a roll copper foil packaging device and a method for using the same. The device has the following beneficial effects:

[0018] In the present invention, the copper foil is wound by driving the winding roller through a motor. During the winding, the rubber plug inside the limit tube realizes the movement of the slide bar, thereby realizing the movement of the mounting frame. If the winding of the copper foil causes the winding roller to be subjected to excessive tension, the air pressure inside the limit tube changes, the mounting frame slides on the slide bar, and the gas squeezes the rubber sleeve inside the slide bar to deform it. The gas in the slide bar flows through the air holes to realize the deformation of the rubber sleeve, thereby realizing the adjustment of the dynamic tension of the copper foil. When the winding roller is working, the slide bar dynamically slides in the limit tube, and at the same time, a pressure buffer is given to the slide bar in combination with the rubber sleeve. Regardless of whether the mounting frame and the winding roller are subjected to large tension or small tension, the tension of the copper foil intermediate product can be dynamically regulated to ensure good winding of the copper foil.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Example:

[0032] like Figure 1-10As shown, the embodiment of the present invention provides a roll copper foil packaging device, including a base 8, a mounting seat 9 and a mounting frame 5. A groove 12 is provided in the middle of the upper surface of the base 8. The bottom end of the mounting frame 5 is slidably connected in the groove 12 through a slide bar 13. Both the front and rear ends of the mounting frame 5 are fixedly connected to one end of a slide rod 4. A rubber plug 14 is provided on the outer periphery of the end of the slide rod 4 away from the mounting frame 5. A rubber sleeve 19 is provided inside the end of the slide rod 4 away from the mounting frame 5. Through the slide rod 4 sliding inside the limit tube 1, the pressure gauge 2 can detect the air pressure inside the limit tube 1, and the force on the slide rod 4 can be clearly detected. At the same time, when the winding roller 16 is working, the slide bar 4 dynamically slides in the limit tube 1, and at the same time, the rubber sleeve 19 is combined to give the slide bar 4 a pressure buffer. No matter whether the mounting frame 5 and the winding roller 16 are subjected to a large tension or a small tension, when the winding roller 16 becomes larger, the tension of the copper foil can be dynamically adjusted, thereby ensuring the flexible adjustment of the copper foil tension. At the same time, there is no need for excessive manual intervention in the copper foil tension, and the copper foil will not be deformed due to abnormal tension changes, thereby ensuring the safety of copper foil winding. The interior of the mounting seat 9 is evenly distributed with through grooves 23 from front to back, and the through grooves 23 are connected to the inspection holes through the rotating shaft. The measuring rod 20 and the through slot 23 are both connected with a slide slot 24 at the rear side, and a top block 25 is slidably arranged in the slide slot 24 from top to bottom in sequence. A roller 10 is rotatably arranged on the upper part of one side of the base 8, and a roller 2 11 is arranged on the upper part of the roller 10. When the copper foil is wound by the winding roller 16, the bottom of the copper foil rubs against the top of the measuring rod 20. The top of the measuring rod 20 is in an arc shape. If there is a bulge at the bottom of the copper foil, the copper foil will push the measuring rod 20 to realize the rotation of the measuring rod 20 in the through slot 23. The U-shaped protrusion of the measuring rod 20 will push the top block 25. The moving distance of the measuring rod 20 can push different The top block 25 of different lengths is shorter, and the moving distance of the detection rod 20 is longer, then the bulge of the copper foil impurities is larger. The top block 25 presses against the counting switch 27 for counting. Different counting switches 27 count copper foil impurities of different depths. Through the setting of different contacts, it can be ensured that the defects on the surface of the copper foil can be detected, and the quality of the copper foil can be directly controlled during winding. The quality of the copper foil can be known during winding, and mechanical precise monitoring is realized, which saves manpower. At the same time, no human visual observation is required, which ensures the inspection accuracy of the copper foil and improves work efficiency.

[0033] The rubber plugs 14 are all slidably arranged in the limit tubes 1, and the limit tubes 1 are all arranged at the four corners of the base 8. The middle part of the limit tube 1 away from the rubber plug 14 is installed with an air pipe 3, and the upper side of the limit tube 1 away from the sliding rod 4 is installed with a pressure gauge 2. The limit tubes 1 are on both sides of the base 8, and there are four of them in total. When working, the limit tubes 1 on one side of the mounting frame 5 are a group. In this way, the sliding rod 4 in the limit tube 1 can uniformly push the mounting frame 5 to move, and the mounting frame 5 slides on the sliding bar 13 to keep the mounting frame 5 stable. The pressure gauge 2 can detect the movement of the mounting frame 5 through the pressure in the limit tube 1. For example, if the copper foil is subjected to tension to one side, the sliding rod 4 on one side will push the rubber plug 14 to move, and the limit tube 1 on this side will be subjected to gas pressure, and the pressure gauge 2 The value changes. Secondly, if the pressure on one side is too high, the gas inside the limit tube 1 compresses the rubber sleeve 19 to achieve pressure regulation inside the limit tube 1, so that the copper foil will not break or even stretch out due to excessive tension. The interior of the slide rod 4 is hollow, and the upper part of the slide rod 4 close to one end of the mounting frame 5 is provided with air holes 15. When the pressure in the limit tube 1 becomes larger, the rubber sleeve 19 is compressed, and the gas inside the hollow slide rod 4 flows out through the air holes 15. A winding roller 16 is provided on the inner side of the mounting frame 5. Both ends of the winding roller 16 are inlaid with quadrangular prisms 18. The quadrangular prism 18 at one end is installed on one side of the mounting plate 6 through a bearing, and the quadrangular prism 18 at the other end rotates through the mounting frame 5 and the quadrangular prism 18 at the other end is fixedly connected to the driving end of the motor 17. The motor 17 is installed On one side of the mounting frame 5, the motor 17 realizes the winding roller 16 winding the copper foil through the quadrangular prism 18. During the winding, the slide bar 4 slides in the limit tube 1 through the rubber plug 14 due to the air pressure. If the winding of the copper foil causes the winding roller 16 to be subjected to excessive tension, the air pressure inside the limit tube 1 changes, and the mounting frame 5 slides on the slide bar 13. The gas squeezes the rubber sleeve 19 inside the slide bar 4 to deform it. The gas in the slide bar 4 flows through the air hole 15 to realize the deformation of the rubber sleeve 19, thereby realizing the adjustment of the dynamic tension of the copper foil and the quality inspection of the copper foil. When the winding roller 16 winds the copper foil, the bottom of the semi-finished copper foil rubs against the top of the detection rod 20. The top of the detection rod 20 is arc-shaped. If there is dirt or impurities on the bottom of the copper foil, the copper foil will push the detection rod 20 to realize the detection rod 20. The U-shaped protrusion of the detection rod 20 will push the top block 25 when it rotates in the through groove 23. The moving distance of the detection rod 20 can push the top blocks 25 of different lengths. The shorter the top block 25 that is touched, the longer the moving distance of the detection rod 20, and the greater the bulge of the copper foil. The top block 25 presses against the counting switch 27 for counting. Different counting switches 27 count the copper foil protrusions of different depths. The mounting plate 6 is threadedly connected to the upper part of one side of the mounting frame 5. A square hole is formed between the mounting plate 6 and the mounting frame 5, and a limiting column 7 is embedded in the square hole. The side of the mounting plate 6 away from the quadrangular prism 18 is evenly distributed with hexagonal holes. The limiting column 7 is used to prevent the mounting plate 6 and the mounting frame 5 from rotating in the thread, and the displacement of the winding roller 16 is prevented. The hexagonal hole facilitates the insertion of a wrench into the mounting plate 6 for rotation.The mounting plate 6 is mounted on the mounting frame 5, and one side of the upper surface of the base 8 is connected to the mounting seat 9 through an electric push rod 21. The electric push rod 21 is arranged on both sides of the bottom end of the mounting seat 9. The electric push rod 21 can flexibly adjust the height of the mounting seat 9 to ensure that it fits normally on the bottom of the copper foil, does not deform the copper foil, and does not cause the copper foil to be unable to contact. The upper and middle parts of the detection rod 20 are set to be U-shaped and the U-shaped protrusion is directly opposite to the slide groove 24. When the detection rod 20 rotates, it can accurately squeeze the top block 25. The top block 25 extends in the through groove 23 and the top block 25 is shortened from top to bottom. One end of the top block 25 is aligned in the slide groove 24 and the top block 25 is connected to the inner wall of the slide groove 24 through the spring 26. The spring 26 is shortened from top to bottom. The inner wall of the slide groove 24 on the side of the spring 26 facing the top block 25 is provided with a counting switch 27. The counting switch 27 and the top block 25 are in one-to-one correspondence. The spring 26 is a light spring to ensure that the top block 25 automatically resets inside the through groove 23. The counting switch 27 can well ensure repeated counting. The shorter the top block 25 is, the more the counting switch 27 with greater copper foil deformation can be detected. The counting switch 27 can count again and again. The counting switch 27 is a prior art and will not be described in detail here. The bottom side of the detection rod 20 is connected to the lower side wall of the through groove 23 through the spring 1 22. The spring 1 22 is a light spring. As long as it is subjected to force, it will be compressed and deformed. When the detection rod 20 moves, it can realize the automatic reset of the detection rod 20 in time to ensure normal use.

[0034] A method for using a roll copper foil packaging device comprises the following steps:

[0035] After the first and second rollers 10 and 11 are rotated, the first rollers 10 and 11 are rotated together, and the second ...

[0036] Step 2. During winding, the motor 17 realizes the winding roller 16 winding the copper foil through the quadrangular prism 18. During winding, the slide bar 4 slides in the limit tube 1 through the rubber plug 14 due to air pressure. If the winding of the copper foil causes the winding roller 16 to be subjected to excessive tension, the air pressure inside the limit tube 1 changes, and the mounting frame 5 slides on the slide bar 13. The gas squeezes the rubber sleeve 19 inside the slide bar 4 to deform it. The gas in the slide bar 4 flows through the air hole 15 to realize the deformation of the rubber sleeve 19, thereby realizing the adjustment of the dynamic tension of the copper foil.
