Description

Technical Field

[0001] This utility model is a copper foil testing device for a copper foil production machine, belonging to the field of copper foil testing. Background Technology

[0002] In today's rapidly developing electronics industry, copper foil, as a key basic material for core components such as printed circuit boards (PCBs) and lithium-ion batteries, directly determines the performance and reliability of electronic products. With the explosive growth in demand for copper foil from fields such as 5G communication and new energy vehicles, the industry's requirements for the surface quality of copper foil are becoming increasingly stringent. Any minute defects such as pinholes, burrs, or uneven thickness can lead to serious problems such as short circuits and reduced battery capacity. Therefore, efficient and accurate online inspection technology for copper foil has become a core link in ensuring product quality and production efficiency.

[0003] Traditional copper foil inspection devices often operate independently using single functional modules, separating the inspection and marking processes. Some inspection devices are only equipped with CCD cameras for defect identification, but lack effective light-shielding protection measures. External light interference causes blurry image acquisition. Other devices, although equipped with light-shielding structures, cannot be linked with the inspection module in real time, making it difficult to quickly adjust the light-shielding range when the copper foil width changes, affecting the continuity of inspection. Therefore, it is necessary to design a copper foil inspection device for copper foil production machines. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a copper foil testing device for a copper foil production machine to solve the problems mentioned in the background art.

[0013] The beneficial effects of this utility model are:

[0014] 1. The three modules of detection, light shielding, and marking work closely together to form an integrated closed-loop process of "detection-light shielding-marking". The light shielding component isolates external interference in real time, the CCD detection component scans quickly, and the laser marking component marks instantly. The second lead screw located in the slide grooves at both ends of the top plate acts as a positive and negative lead screw. When it rotates, it drives the first lead screw nuts on both sides to move synchronously through the L-shaped plate and the light shielding component. When the width of the copper foil changes, the light shielding component can quickly adjust the coverage area to further refine the light shielding area. During the copper foil operation, it continuously isolates external light interference, providing a stable optical environment for CCD detection behind the foil outlet of the foil production machine and ensuring the quality of image acquisition.

[0015] 2. Driven by the third lead screw, the second lead screw nut moves the CCD detection assembly laterally along the slide groove in the center of the top plate, achieving dynamic scanning of the full width of the copper foil. Operators can control the rotation of the vertical lead screw by rotating the handle, causing the third lead screw nut, connecting plate, and carrier plate to move up and down, precisely adjusting the vertical distance between the CCD detection camera and the copper foil to adapt to the detection needs of copper foils of different thicknesses. The clamping plate is mainly used for clamping and fixing the CCD detection camera. Its cooperation with the adjustment groove on the carrier plate facilitates quick camera installation and removal, significantly reducing maintenance difficulty and shortening downtime for repairs. Meanwhile, the uniform illumination provided by the ring light ensures clear and complete images.

[0016] 3. Once the CCD camera detects a copper foil defect, the first servo motor immediately starts, driving the first lead screw to rotate. This causes the movable plate mounted on the slide rod and the first lead screw to move laterally, quickly transporting the laser marking assembly above the defect location. In the laser marking assembly, the movable slot is horizontally positioned. After the rotary motor starts, it drives the movable frame to rotate around the rotary motor. The laser is used to mark the defect area with a frame, clearly identifying the defect location. At the same time, the hydraulic telescopic rod pushes the laser marking machine to slide within the horizontal movable slot through the connecting plate, flexibly adjusting the marking range. Whether it is a tiny pinhole or a large area defect, accurate and suitable marking can be achieved, ensuring clear and accurate marking of the defect location even when the copper foil is continuously running.

[0043] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0044] Please see Figures 1 to 7This utility model provides a technical solution: a copper foil detection device for a copper foil production machine, including a top plate 1, with outwardly extending mounting plates 101 on both sides of one end of the top plate 1, and three equally spaced sliding grooves 103 at the bottom of the top plate 1. A movable plate 9 is arranged between two mounting plates 101, and a laser marking component 10 is installed at the bottom of the movable plate 9. A third lead screw 15 is installed in the sliding groove 103 located in the center of the top plate 1, and a third servo motor 11 with its output end connected to the third lead screw 15 is installed at the center of one side of the top plate 1. A second lead screw nut 17 is fitted on the third lead screw 15, and a CCD detection component 16 is installed at the bottom of the second lead screw nut 17. A second lead screw 13 is installed in the sliding grooves 103 at both ends of the top plate 1, and the second lead screw 1... 3 is a positive and negative threaded lead screw. The second lead screw 13 is symmetrically provided with a first threaded nut 12 that is adapted to it. The bottom of the four first threaded nuts 12 are all connected to the light shielding component 3. The CCD detection component 16 is located inside the light shielding component 3. The third lead screw 15 in the central slide groove 103 cooperates with the second threaded nut 17 to drive the CCD detection component 16 to perform precise horizontal scanning and realize comprehensive detection of the copper foil surface. The positive and negative threaded second lead screws 13 in the slide grooves 103 at both ends drive the light shielding component 3 to open and close through the first threaded nut 12 and the L-shaped plate 1201, so that the light shielding range can closely fit the width of the copper foil, effectively isolate external light interference, provide a stable optical environment for the CCD detection camera 1603, and significantly improve the clarity of image acquisition and the accuracy of detection results.

[0045] For example, a slide rod 7 is fixed at one end of the two mounting plates 101 near the top plate 1, and a first lead screw 8 is rotatably connected at the other end of the two mounting plates 101 away from the top plate 1. A first servo motor 4 is fixed on the mounting plate 101 on one side of the first lead screw 8, and the output end of the first servo motor 4 is connected to the first lead screw 8. A movable plate 9 is mounted on the slide rod 7 and the first lead screw 8, and the movable plate 9 has a slide rod groove that matches the outer diameter of the slide rod 7 and a lead screw groove that matches the first lead screw 8. The slide rod 7 provides rigid support for the movable plate 9 and limits its radial sway during movement. When the CCD detection component 16 identifies the location of the copper foil defect, the first servo motor 4 can quickly drive the first lead screw 8, causing the movable plate 9 and the laser marking component 10 to move to the corresponding position for marking.

[0046] For example, both ends of the top plate 1 are provided with protrusions 102, and the bottom of each protrusion 102 is fixed with a column 2. A light-shielding edge 14 is installed at the bottom edge of the top plate 1. A second servo motor 5 is installed at the center of the top plate 1 away from the third servo motor 11. The output end of the second servo motor 5 is connected to two second lead screws 13 through a sprocket mechanism 6. The sprocket mechanism 6 includes a drive wheel connected to the output end of the third servo motor 11 and two driven wheels connected to the ends of the second lead screws 13 respectively, as well as a chain for driving the drive wheel and the driven wheels. A light-shielding edge 14 is installed at the bottom edge of the top plate 1. The light-shielding edge 14 installed at the bottom edge of the top plate 1 works in conjunction with the light-shielding component 3 to form an all-round light-shielding protection system.

[0047] Please see Figure 2 The light-shielding assembly 3 includes a side plate 301, a main plate 302, and a telescopic plate 303. The top two ends of the side plate 301 are fixedly connected to the L-shaped plates 1201 corresponding to the bottom of the first nut 12 by bolts. Main plates 302 are provided at both ends between the two side plates 301. Telescopic plates 303 are retractably connected to both sides of the main plate 302, and the side of the telescopic plate 303 away from the main plate 302 is connected to the end of the side plate 301. Telescopic grooves 3021 with an inner width matching the thickness of the telescopic plate 303 are provided on both sides of the main plate 302. The telescopic plates 303 and the telescopic plate 303... The sliding connection of the expansion groove 3021 and the four telescopic plates 303, each with a horizontally evenly arranged limiting groove 3031 at the end away from the CCD detection component 16, are all provided with limiting protrusions 3022 on the inner sidewall of the expansion groove 3021 that match the limiting groove 3031. The side plate 301 is fixedly connected to the L-shaped plate 1201 below the first screw nut 12 by bolts, which can quickly respond to changes in the width of the copper foil and move synchronously under the drive of the second screw 13. The pull-out connection design between the main board 302 and the expansion plate 303 further refines the adjustment accuracy of the light-shielding range. When the width of the copper foil changes, the expansion plate 303 can slide in the expansion groove 3021, and achieve precise positioning through the cooperation of the limiting protrusions 3022 and the limiting groove 3031, ensuring that the light-shielding area is always tightly attached to the edge of the copper foil.

The top of the lifting rail 1601 is connected to the second lead screw nut 17 by bolts, and the mounting structure 1606 is fixed to the bottom of one end of the lifting rail 1601. The rotating handle 1607 is installed at the bottom of the lifting rail 1601, and the vertical lead screw 1604 is rotatably connected inside the lifting rail 1601. The top output end of the rotating handle 1607 is connected to the bottom of the vertical lead screw 1604, and a lifting mechanism is movably connected to the lifting rail 1601. The ring light 1605 is installed at the bottom of the mounting structure 1606 and the lifting structure 1602 is provided with clamps 1608 on both sides near the ring light 1605. A CCD detection camera 1603 is clamped between the clamps 1608. The vertical screw 1604 is driven to rotate by rotating the handle 1607, which drives the lifting structure 1602 to move up and down along the lifting rail 1601 to adjust the distance between the camera and the copper foil surface, ensuring that the camera is at the optimal shooting focal length. The ring light 1605 is fixed to the bottom of the lifting rail 1601 by the mounting structure 1606, which can provide 360° uniform illumination, eliminate shadows in the detection area, and ensure clear and complete images.

[0050] Please see Figure 5The lifting structure 1602 includes a third lead screw nut 16021 adapted to the vertical lead screw 1604, a connecting plate 16022, a carrier plate 16023, an adjusting groove 16024, an adjusting handle 16025, and a bidirectional lead screw 16026. The carrier plate 16023 is located at one end of the lifting rail 1601 near the ring light 1605, and both sides of the carrier plate 16023 are connected to the third lead screw nut 16021 through the connecting plate 16022. Both sides of the lifting rail 1601 are vertically provided with through grooves 16011 whose inner width is adapted to the thickness of the connecting plate 16022. Three horizontal adjusting grooves 16024 are equally spaced on the carrier plate 16023, and the two ends of the upper and lower adjusting grooves 16024 are provided with connecting blocks 16081 that match their shape. The adjusting groove 16024 is located in the center of the carrier plate 16023.

Both the connecting block 16081 and the lead screw sleeve 16082 are fixedly connected to the clamping plate 1608. The cooperation between the third lead screw nut 16021 and the vertical lead screw 1604 realizes the precise vertical adjustment of the lifting structure 1602. When the operator rotates the rotating handle 1607, the vertical lead screw 1604 drives the third lead screw nut 16021 to rise and fall smoothly along the lifting rail 1601. When the bidirectional lead screw 16026 rotates, the lead screw sleeves 16082 on both sides drive the clamping plate 1608 to move synchronously in opposite directions. Combined with the auxiliary positioning of the connecting block 16081 in the upper and lower adjustment groove 16024, the CCD inspection camera 1603 can be quickly disassembled and assembled, and maintenance or replacement can be completed quickly.

[0051] Please see Figure 5The mounting structure 1606 includes a mounting bracket 16061, fastening knobs 16062, limiting bolts 16063, and mounting rails 16064.

Mounting rails 16064 are fixed to both sides of the mounting bracket 16061 near the CCD detection camera 1603, and limiting bolts 16063 are provided within both mounting rails 16064. The mounting rail 16064 is threadedly connected to the top of the ring light 1605. The mounting bracket 16061 adopts a "U"-shaped cross-section design, which matches the width and height of the lifting rail 1601 to form a tightly wrapped installation. When the fastening knobs 16062 on both sides are rotated, their ends can evenly press against the side wall of the lifting rail 1601, firmly fixing the mounting bracket 16061 at the appropriate height of the lifting rail 1601, ensuring that the ring light 1605 is always in the ideal lighting position. The combination design of the mounting rail 16064 and the limiting bolt 16063 gives the ring light 1605 flexible installation and adjustment capabilities, ensuring that the light evenly covers the copper foil surface and eliminates shadows in the detection area.

[0052] Detailed Implementation: In use, the third servo motor 11 drives the third lead screw 15 to rotate. The third lead screw 15 cooperates with the second lead screw nut 17 to drive the CCD detection component 16 to scan horizontally back and forth along the copper foil running direction. In the CCD detection component 16, the operator rotates the rotating handle 1607 to drive the vertical lead screw 1604 to rotate. The vertical movement of the lifting structure 1602 is achieved through the third lead screw nut 16021, the connecting plate 16022, and the carrier plate 16023, accurately adjusting the distance between the CCD detection camera 1603 and the copper foil surface. The ring light 1605 is fixed to the bottom of the lifting rail 1601 through the mounting structure 1606 to provide uniform illumination and ensure clear and complete detection images. When the positive and negative tooth second lead screw 13 in the sliding grooves 103 at both ends of the top plate 1 rotates, it drives the first lead screw nut 12 through L The shaping plate 1201 drives the light-shielding component 3 to open and close synchronously. The side plate 301 of the light-shielding component 3 moves with the first nut 12. The pull-out connection between the main plate 302 and the telescopic plate 303 further refines the light-shielding range. When the CCD detection camera 1603 identifies the copper foil defect, the first servo motor 4 drives the first lead screw 8 to rotate, which drives the movable plate 9 installed on the slide rod 7 and the first lead screw 8 to move laterally, transporting the laser marking component 10 to above the defect position. In the laser marking component 10, the rotary motor 1003 drives the rotating sleeve 1004 to rotate, which drives the movable frame 1005 to achieve 360° rotation, marking the defect area with a frame. The hydraulic telescopic rod 1008 pushes the laser marking machine 1006 to slide in the horizontal movable groove 10051 through the connecting plate 10062, flexibly adjusting the marking range.
