Description

Technical Field

[0001] The present invention relates to the technical field of copper foil detection, and particularly relates to a thickness detection device for a rolled metal copper foil. Background Technique

[0002] Industrial copper foils can be commonly classified into two categories: rolled copper foils and electrolytic copper foils. Among them, rolled copper foils have better ductility and other characteristics and were the copper foils used in early flexible board manufacturing processes, while electrolytic copper foils have the advantage of lower manufacturing costs compared to rolled copper foils. For either type of copper foil, thickness detection is required during production winding.

[0003] The prior art discloses a copper foil uniform thickness detection and processing device with a publication number of CN216081336U. Through the design of adding a processing base plate, a uniform support, a fixing plate, a first uniform roller, an adjusting plate, a second uniform roller, a micro motor, a support bracket, a rotating rod, a through rod, a clamping ring, a motor, and a laser thickness gauge, it can detect the thickness of copper foil during the production process and can also make the thickness of the copper foil uniform again before detection, with strong functionality. However, when the copper foil is improperly extruded or transported, the edges are prone to warping, which will have a greater impact on the detection results. Moreover, when there are debris on the surface of the copper foil, it will also affect the accuracy of copper foil thickness detection. Summary of the Invention

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. First, the copper foil is preliminarily detected by the preliminary inspection structure. When the thickness of the copper foil strip is abnormal, the induction probe will be triggered. The induction probe emits a signal, which is processed by the single-chip microcomputer and then controls the finishing structure to smooth the edge of the copper foil strip and blow off the dust and debris on the surface of the copper foil strip at the same time. After the preliminary treatment is completed, the re-inspection structure will perform a second measurement.

[0016] 2. When the distance between the movable block and the fixed block changes, the precision rack will drive the first gear to rotate, so that the second gear rotates. The second gear with a larger diameter drives the third gear with a smaller diameter to rotate, so as to realize the conversion of the slight distance change between the movable block and the fixed block into a larger angle change on the pointer, thereby improving the detection accuracy;

[0017] 3. The arranged induction probe can slide along the slip ring. After the induction probe is placed at the specified position, when the pointer rotates past the induction probe, the induction probe will be triggered. The induction probe emits a signal, which is processed by the single-chip microcomputer and then controls the finishing structure to perform multiple smoothing treatments on the edge of the copper foil strip and blow off the dust and debris on the surface of the copper foil strip at the same time, preventing other factors from affecting the copper foil.

Detailed implementation manners

[0036] 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.

[0037] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present invention.

[0038] Refer to Figure 1 - Figure 17, a device for detecting the thickness of a metal copper foil roll, comprising a copper foil strip 1, a preliminary inspection structure 2, a re-inspection structure 3 and a finishing structure 4. The preliminary inspection structure 2 and the re-inspection structure 3 are both clamped outside the copper foil strip 1 for detecting the thickness of the copper foil strip 1. The finishing structure 4 is located between the preliminary inspection structure 2 and the re-inspection structure 3 for processing the copper foil strip 1 with abnormal thickness. The preliminary inspection structure 2 and the re-inspection structure 3 have the same structure. The preliminary inspection structure 2 and the re-inspection structure 3 both include two parallel pressure rollers 5. The two pressure rollers 5 are located on the upper and lower sides of the copper foil strip 1. Both ends of the two pressure rollers 5 are movably connected with a detection structure 6. The bottom of the detection structure 6 is fixedly connected with a mounting bracket 7. The detection structure 6 includes a limiting plate 8. A sliding groove 9 is formed on the outer wall of the limiting plate 8. An activity block 11 and a fixed block 12 are arranged on the outside of each limiting plate 8. The fixed block 12 is fixedly connected with the outer wall of the limiting plate 8. The end of the pressure roller 5 passes through the limiting plate 8 and is rotatably connected with the fixed block 12. The end of the other pressure roller 5 passes through the sliding groove 9 and is rotatably connected with the inner wall of the activity block 11. A spring 16 is fixedly connected between the activity block 11 and the fixed block 12. A measuring disk 13 is fixedly connected to the outer wall of the fixed block 12. A pointer 14 is rotatably connected to the middle of the measuring disk 13. A transmission structure for adjusting the rotation angle of the pointer 14 according to the distance between the activity block 11 and the fixed block 12 is installed inside the fixed block 12. A slip ring 17 is fixedly connected to the outside of the measuring disk 13. An induction probe 15 cooperating with the pointer 14 is slidably connected to the outer wall of the slip ring 17.

[0039] When the present invention detects the thickness of the copper foil strip 1, the preliminary inspection structure 2 first conducts a preliminary inspection on the copper foil. The two pressure rollers 5 on the preliminary inspection structure 2 will clamp the copper foil strip 1. The change in the distance between the activity block 11 and the fixed block 12 represents the thickness of the copper foil. The set transmission structure can output the distance between the activity block 11 and the fixed block 12 to the pointer 14 after amplification. The thickness of the copper foil is shown through the rotation angle of the pointer 14 and the scale on the measuring disk 13. This method can detect and display even tiny distance changes, with higher precision in detecting the thickness of the copper foil strip 1. Moreover, the set induction probe 15 can slide along the slip ring 17. After placing the induction probe 15 at a specified position, when the pointer 14 rotates past the induction probe 15, the induction probe 15 will be triggered, and the induction probe 15 will send a signal. After being processed by a single-chip microcomputer, it controls the finishing structure 4 to smooth the edge of the copper foil strip 1 and blow off the dust and debris on the surface of the copper foil strip 1 at the same time. After the preliminary processing is completed, the re-inspection structure 3 conducts a second measurement. If the measurement result of the re-inspection structure 3 is still that the copper foil thickness is abnormal, it is determined that the copper foil thickness is abnormal, and then an alarm is given through the single-chip microcomputer, and the whole device is controlled to stop, so as to prevent misjudgment.

[0040] As a preferred embodiment of the present invention, there is an interference fit between the induction probe 15 and the slip ring 17, so that the induction probe 15 will be stuck on the slip ring 17 after being adjusted to the designated position and is difficult to move by itself. Two conductive elastic contacts are installed on the induction probe 15. When the pointer 14 sweeps across the two elastic contacts, the elastic contacts bend and connect together, thereby emitting an electrical signal. The number of induction probes 15 can be one or two. With two induction probes 15, an alarm can be issued when the detected thickness is too low or too high, so as to achieve the effect of effectively monitoring the thickness of the copper foil and prevent false alarms caused by other factors.

[0041] Specifically, a limiting post 10 for limiting is arranged inside the movable block 11 and the fixed block 12. Both ends of the limiting post 10 are fixedly connected with stop pieces. The movable block 11 and the fixed block 12 are both slidably connected to the outer wall of the limiting post 10. The transmission structure includes a precision rack 19. The precision rack 19 is installed on one side of the movable block 11 close to the fixed block 12. An activity groove 20 for the precision rack 19 to move is opened on one side of the fixed block 12 close to the movable block 11. The inner wall of the activity groove 20 is rotatably connected with a first gear 18 meshing with the precision rack 19. A second gear 21 and a third gear 22 are also rotatably connected inside the fixed block 12. The second gear 21 meshes with the third gear 22. The axis of the second gear 21 is fixedly connected with the axis of the first gear 18. The axis of the third gear 22 is fixedly connected with the axis of the pointer 14. The transmission structure is used to amplify the slight distance change between the movable block 11 and the fixed block 12 into an angular change to achieve a more accurate detection effect. Specifically, when the distance between the movable block 11 and the fixed block 12 changes, the precision rack 19 will drive the first gear 18 to rotate, thereby causing the second gear 21 to rotate. The second gear 21 with a larger diameter drives the third gear 22 with a smaller diameter to rotate, so as to convert the slight distance change between the movable block 11 and the fixed block 12 into a larger angular change on the pointer 14, thereby improving the detection accuracy.

[0042] Specifically, the sorting structure 4 includes two vertical plates 23 which are located on both sides of the copper foil strip 1. At both the upper and lower ends of the vertical plates 23, two cross plates 24 are fixedly connected. Between the two cross plates 24 near the upper end of the vertical plate 23, two symmetrically distributed flattening structures 25 are movably connected. Between the two cross plates 24 near the lower end of the vertical plate 23, two symmetrically distributed flattening structures 25 are also movably connected. On the outer wall of each flattening structure 25, a transmission rack 27 is fixedly connected. Between the two cross plates 24 near the upper end of the vertical plate 23, a transmission gear 26 is rotatably connected. Between the two cross plates 24 near the lower end of the vertical plate 23, a transmission gear 26 is also rotatably connected. The two transmission racks 27 between the two cross plates 24 near the upper end of the vertical plate 23 are engaged with the transmission gear 26. The two transmission racks 27 between the two cross plates 24 near the lower end of the vertical plate 23 are engaged with another transmission gear 26. On the outer wall of the cross plate 24, a limiting groove 28 for limiting the transmission rack 27 is formed. On the outer wall of the cross plate 24, a push rod 29 is fixedly connected. One end of the push rod 29 is fixedly connected with a connecting block 30. The push rod 29 is connected to the flattening structure 25 through the provided connecting block 30. There are two push rods 29 which respectively control the movement of the C-shaped frames 31 on the upper and lower sides. The flattening structure 25 includes a C-shaped frame 31. Inside the C-shaped frame 31, a vertically arranged sliding rod 32 is fixedly connected. On the outer wall of the sliding rod 32, a first connecting strip 34 is slidably connected. One end of the first connecting strip 34 is fixedly connected with a second connecting strip 35. The end of the second connecting strip 35 far from the first connecting strip 34 is fixedly connected with a pressing block 36. On both sides of the end of the second connecting strip 35 near the first connecting strip 34, guiding columns 41 are fixedly connected. On both sides of the first connecting strip 34, limiting tracks 33 are arranged. The second connecting strip 35 is slidably connected to the limiting tracks 33 through the provided guiding columns 41. The outer wall of the limiting track 33 is fixedly connected with the outer wall of the cross plate 24. When the initial inspection structure 2 detects that the thickness of the copper foil strip 1 is abnormal, the two push rods 29 are controlled to make reciprocating movements synchronously. The connecting blocks 30 on the push rods 29 drive the C-shaped frames 31 to move. When the C-shaped frames 31 move, they will drive the transmission racks 27 to move along the limiting grooves 28. Under the transmission of the transmission gears 26 and the transmission racks 27, the adjacent C-shaped frames 31 will also move relatively. When the C-shaped frames 31 move, since the guiding columns 41 on the second connecting strip 35 are limited by the limiting tracks 33, the limiting tracks 33 will move up and down along the sliding rod 32. When the pressing block 36 is pushed to the edge of the copper foil strip 1, the pressing block 36 contacts the copper foil strip 1 and flattens the warped edge of the copper foil strip 1. And the air inlet joint 40 is used to connect high-pressure gas, and the high-pressure gas is ejected from the jet head 39, so that the dust and debris on the surface of the copper foil strip 1 can be cleaned, thereby eliminating the influence of other factors on the measurement and preventing false alarms from occurring.

[0043] Specifically, a long arc groove 42 is formed on the outer wall of the limit track 33. The outer wall of the limit track 33 is also provided with a first horizontal groove 43, an inclined groove 44 and a second horizontal groove 45. Both the first horizontal groove 43 and the second horizontal groove 45 are horizontally arranged. The lower end of the long arc groove 42 is connected to one end of the first horizontal groove 43. One end of the first horizontal groove 43 far from the long arc groove 42 is connected to the lower end of the inclined groove 44. The middle part of the inclined groove 44 is connected to one end of the second horizontal groove 45. One end of the second horizontal groove 45 far from the inclined groove 44 is connected to the long arc groove 42. A movable baffle 46 is rotatably connected to the connection part of the second horizontal groove 45 and the long arc groove 42. The lower end of the movable baffle 46 is rotatably connected to the inner wall of the limit track 33. Among them, the guide post 41 is slidably connected to the limit track 33. When the C-shaped frame 31 moves in a direction away from the transmission gear 26, the guide post 41 will be limited by the limit track 33 and first slide down along the long arc groove 42 until it slides into the first horizontal groove 43. At this time, the pressing block 36 moves to the edge of the copper foil strip 1, and at the same time, the bottom of the pressing block 36 contacts the copper foil strip 1. When passing through the first horizontal groove 43 for a certain distance, the pressing block 36 will flatten the edge of the copper foil strip 1. Subsequently, the guide post 41 slides along the inclined groove 44, causing the pressing block 36 to lift as a whole, and the pressing block 36 is separated from the copper foil strip 1. Then the push rod 29 contracts, and the guide post 41 slides into the second horizontal groove 45 along the inclined groove 44. When passing through the movable baffle 46, it pushes the movable baffle 46 to rotate along the bottom rotating shaft into the long arc groove 42, so that the guide post 41 can slide from the inside of the second horizontal groove 45 into the long arc groove 42 again and slide along the long arc groove 42 to the top of the long arc groove 42, so that when the pressing block 36 is retracted as a whole, the bottom of the pressing block 36 no longer contacts the surface of the copper foil strip 1, preventing the edge of the copper foil strip 1 from curling again.

[0044] Specifically, a unwind roller 49 is installed at one end of the copper foil strip 1, a winding roller 51 is installed at the other end of the copper foil strip 1, and two guide rollers 50 for guiding the copper foil strip 1 are arranged between the unwind roller 49 and the winding roller 51.

[0045] Specifically, an arc-shaped pressing strip 37 is movably connected to the outer edge of one side of the briquette 36 close to the copper foil strip 1, and a straight pressing strip 38 is movably connected to the side of the briquette 36 close to the copper foil strip 1. A plurality of receiving cavities 47 for limiting the arc-shaped pressing strip 37 are formed at the outer edge of the briquette 36, and a receiving cavity 47 for receiving the straight pressing strip 38 is also formed on the outer wall of the briquette 36. Rubber particles 48 are fixedly connected to the inner wall of the receiving cavity 47. A plurality of air jet nozzles 39 are fixedly connected to the outer wall of the briquette 36 close to the unwinding roller 49, and an air inlet joint 40 communicated with the plurality of air jet nozzles 39 is fixedly connected to the outer wall of the briquette 36. Specifically, when the briquette 36 presses the surface of the copper foil strip 1, the arc-shaped pressing strip 37 and the straight pressing strip 38 on the two briquettes 36 will elastically change according to the thickness of the copper foil strip 1 when pressing the copper foil strip 1. When the thickness of the copper foil strip 1 is relatively thick, the arc-shaped pressing strip 37 and the straight pressing strip 38 will slide along the receiving cavity 47 and press the rubber particles 48. When the thickness of the copper foil strip 1 is relatively thin, the rubber particles 48 will also eject the arc-shaped pressing strip 37 and the straight pressing strip 38 so that the arc-shaped pressing strip 37 and the straight pressing strip 38 will both fit the surface of the copper foil strip 1.

[0046] Working principle: When the present invention detects the thickness of the copper foil strip 1, the copper foil is preliminarily detected by the preliminary detection structure 2 first. The two pressing rollers 5 on the preliminary detection structure 2 will clamp the copper foil strip 1. The change in the distance between the movable block 11 and the fixed block 12 represents the thickness of the copper foil. The set transmission structure can amplify the distance between the movable block 11 and the fixed block 12 and output it to the pointer 14. The thickness of the copper foil is shown through the rotation angle of the pointer 14 and the scale on the measuring disc 13. This method can detect and display even tiny spacing changes, and has a higher detection accuracy for the thickness of the copper foil strip 1. Moreover, the set induction probe 15 can slide along the slip ring 17. After placing the induction probe 15 at a specified position, when the pointer 14 rotates past the induction probe 15, the induction probe 15 will be triggered, and the induction probe 15 will send a signal. After being processed by the single-chip microcomputer, it controls the finishing structure 4 to perform multiple smoothing processes on the edge of the copper foil strip 1, and at the same time blows off the dust and debris on the surface of the copper foil strip 1. After the preliminary processing is completed, the re-inspection structure 3 performs a second measurement. If the measurement result of the re-inspection structure 3 is still that the copper foil thickness is abnormal, it is determined that the copper foil thickness is abnormal, and then the single-chip microcomputer gives an alarm and controls the entire device to stop, so as to prevent misjudgment.

[0047] Further explanation, the above fixed connection, unless otherwise clearly specified and limited, should be understood in a broad sense. For example, it can be welding, gluing, or integrally formed setting, etc., which are common means well-known to those skilled in the art.

[0048] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
