Description

Technical Field

[0001] This utility model relates to the field of die-cutting quality inspection technology, and in particular to a manual inspection device for folded SCF. Background Technology

[0002] As a key composite material in the production of flexible circuit boards, SCF has an internal copper foil structure that is sensitive to bending stress. Excessive bending can easily lead to copper foil breakage and performance failure. Therefore, SCF monomers are generally supplied in roll form in the industry, and the monomers after the roll is unrolled need to be temporarily stored and transported in a Z-shaped folding manner to avoid damage to the copper foil.

[0003] Currently, existing SCF lamination lines are highly automated. Although SCF units are supplied in rolls, the copper foil is not resistant to excessive bending, so the rolls need to be folded in a Z-shape. This shape means that quality inspection still relies on manual folding: operators need to manually unfold the folded SCF to check for surface scratches, foreign objects, hole blockages, misalignment, and other defects. However, there are obvious problems: folding back and forth causes the product to wrinkle and shift easily, requiring additional sorting after inspection, which is inefficient. Furthermore, the light source is unstable and lacks fixed support when handheld, making it impossible to effectively inspect the hole area, which is easy to miss. Long-term operation can also cause operator fatigue and reduce inspection accuracy. Moreover, existing flexible material inspection devices mostly focus on automated transmission, which are complex in structure and expensive, and are not suitable for flexible manual inspection of small batches and multiple specifications of Z-folded SCF. The industry still lacks a suitable lightweight solution.

[0004] To address this, a manual inspection device for folded SCFs is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a manual inspection device for folded SCF (Super Foil Fabric). This device addresses the problem that while existing SCF bonding lines are highly automated, and SCF units are supplied in rolls, the copper foil is susceptible to excessive bending, requiring the rolls to be folded in a Z-shape. This folding method means quality inspection still relies on manual folding: operators must manually unfold the folded SCF to inspect for surface scratches, foreign objects, hole blockages, misalignment, and other defects. However, this method has significant problems: repeated folding causes the product to wrinkle and shift, requiring additional finishing after inspection, resulting in low efficiency. Furthermore, the handheld operation is hampered by unstable light sources and lack of fixed support, making it difficult to effectively inspect hole areas and leading to missed inspections. Prolonged operation also causes operator fatigue, reducing inspection accuracy. Moreover, existing flexible material inspection devices primarily focus on automated transmission, resulting in complex structures and high costs, making them unsuitable for the flexible manual inspection of small batches and multiple specifications of Z-shaped folded SCF. The industry still lacks a suitable lightweight solution.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a manual inspection device for folded SCF, comprising a base, wherein a test slot and a placement slot are respectively provided on the left and right sides of the bottom inside the base, and an inspection component is provided in the middle inside the base. The inspection assembly includes a bottom frame disposed inside the base, with a light-illuminating structure inside the bottom frame.

[0008] Preferably, a display screen is embedded in the front side of the controller, and the display screen is electrically connected to the controller.

[0009] Preferably, a control button and a dimming knob are respectively provided on the right side of the front side of the display screen. The dimming knob is located on top of the control button, and both the control button and the dimming knob are electrically connected to the controller.

[0010] Preferably, the closed structure includes a fixed sleeve fixedly connected to the bottom front side of the base frame, and a closing cover is rotatably connected to the inner side of the fixed sleeve.

[0011] Preferably, magnetic sheets are embedded in both sides of the rear side of the sealing cover, and magnetic strips are embedded in both sides of the front side of the bottom frame, with the magnetic strips being magnetically connected to the magnetic sheets.

[0012] Preferably, the inner walls of both the test tank and the placement tank are provided with elastic buffer pads, and the elastic buffer pads are made of silicone.

[0013] Preferably, the surface of the inclined transition plate is coated with a Teflon coating, and the inner wall of the bottom frame is bonded with an aluminum foil layer.

[0015] Preferably, a partition is fixedly connected to the middle of the inside of the storage box, and a soft sponge pad is adhered to the bottom side of the inside of the storage box.

[0016] Compared with the prior art, the beneficial effects of this utility model are: 1. This application effectively solves the core problem of manual inspection of Z-shaped folded SCF by setting up a test slot, a placement slot, and an inspection component: the test slot and the placement slot can respectively and orderly store the folded SCF units to be inspected and those that have been inspected, avoiding product creases and displacement caused by manual folding, saving extra sorting steps and improving inspection efficiency; in the inspection component, the horizontal and vertical scale lines of the transparent acrylic plate can quickly locate the hole area, and the top focusing micro-hole, together with the light-illuminating structure below, can accurately focus on the hole area, solving the problem of missed inspection of hole areas caused by unstable light source and lack of support when handheld inspection, while eliminating the need for personnel to hold the device for a long time, reducing operator fatigue and ensuring inspection accuracy; 2. This application ensures the long-term stable operation of the illumination structure by setting a closed structure. At the same time, the closed structure reduces light leakage, allowing the light to be more concentrated and act on the SCF aperture area through the focusing micro-hole, further improving the clarity of the aperture area inspection. This indirectly solves the problem of low light source utilization efficiency in manual inspection. Moreover, the overall structure is simple and lightweight, which is suitable for the manual inspection needs of small batches and multiple specifications of Z-shaped folded SCFs, filling the gap in lightweight solutions in the industry.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-7 The present invention provides the following technical solution: A manual inspection device for folded SCF includes a base 1, with a test slot 2 and a placement slot 3 respectively opened on the left and right sides of the bottom inside the base 1, and an inspection component 4 arranged in the middle inside the base 1. The inspection component 4 includes a bottom frame 401 disposed inside the bottom side of the base 1. A light-illuminating structure 402 is disposed inside the bottom frame 401. A closed structure 403 is disposed on the front side of the bottom frame 401. Baffles 404 are fixedly connected to the front and rear sides of the top of the bottom frame 401. Inclined transition plates 405 are fixedly connected to both sides of the inner side of the baffles 404. The bottom end of the left inclined transition plate 405 is fixedly connected to the top of the test groove 2, and the bottom end of the right inclined transition plate 405 is fixedly connected to the top of the placement groove 3. A transparent acrylic plate 406 is disposed on the top of the inclined transition plate 405 and the baffles 404. The transparent acrylic plate 406 is located on top of the light-illuminating structure 402. A horizontal scale line 407 and a vertical scale line 408 are respectively disposed on the top of the transparent acrylic plate 406. Several focusing micro-holes 409 are opened on the top of the transparent acrylic plate 406.

[0021] In this embodiment: by setting up a base 1, a test slot 2, a placement slot 3, and an inspection component 4, the Z-shaped folded SCF units to be inspected are first placed into the test slot 2 on the left side of the base 1, achieving orderly temporary storage of the products to be inspected and avoiding wrinkles or chaos caused by random stacking. During inspection, the operator takes out a single folded SCF from the test slot 2 and slides it smoothly along the left inclined transition plate 405 to the top surface of the transparent acrylic plate 406. The inclined structure of the inclined transition plate 405 can guide the smooth transmission of the SCF, while the baffle 404 can limit the SCF from deviating from both sides during the sliding process, ensuring that it falls accurately in the inspection area. At this time, the lighting structure 402 in the bottom frame 401 is activated, and the light shines upward, forming a directional beam through the focusing micro-hole 409 on the top of the transparent acrylic plate 406, which accurately acts on the hole area of ​​the SCF. The operator can use the horizontal scale line 407 and the vertical scale line 408 on the acrylic plate to quickly locate the hole area on the SCF and compare the scale to determine whether the hole position is misaligned. Simultaneously, by observing the penetration of the focused beam, defects such as blockages in the aperture area can be visually identified. Scratches and foreign objects on the SCF surface can also be observed. After inspection, qualified SCF units are slid into the placement slot 3 on the right side of the base 1 along the right inclined transition plate 405, completing the storage of inspected products. Throughout the process, the closed structure 403 on the front side of the bottom frame 401 can prevent external dust from entering the light structure 402 and affecting the light effect, and can also reduce light leakage, ensuring the light intensity at the focusing micro-aperture 409, further improving the inspection clarity. This design eliminates the need for manual handling and folding of SCFs. The orderly flow of products is achieved through the test slot 2 and placement slot 3. The inclined transition plate 405 and baffle 404 ensure transmission stability. The horizontal scale line 407, vertical scale line 408, and focusing micro-aperture 409 work together with the light structure 402 to improve inspection accuracy. This design not only solves the problems of low efficiency and high missed detection rate of manual inspection, but also adapts to the manual inspection needs of small batches and multiple specifications of SCFs through a simple structure.

[0022] Specifically, such as Figure 5 As shown, the lighting structure 402 includes a heat dissipation substrate 4021 disposed inside the bottom side of the bottom frame 401. An LED fill light 4022 is disposed on the top of the heat dissipation substrate 4021. The LED fill light 4022 is located at the bottom of the transparent acrylic plate 406. A controller 4023 is disposed on the front side of the front baffle 404. The controller 4023 is electrically connected to the LED fill light 4022.

[0023] Specifically, such as Figure 5 As shown, a display screen 4024 is embedded in the front side of the controller 4023, and the display screen 4024 is electrically connected to the controller 4023.

[0024] Specifically, such as Figure 5As shown, a control button 4025 and a dimming knob 4026 are respectively provided on the right side of the front of the display screen 4024. The dimming knob 4026 is located on top of the control button 4025. Both the control button 4025 and the dimming knob 4026 are electrically connected to the controller 4023.

[0025] In this embodiment: By setting up the lighting structure 402, the heat dissipation substrate 4021 inside the bottom frame 401 directly supports the LED fill light 4022, which can quickly conduct the heat generated by the LED during operation, avoid the lamp body aging due to high temperature, and ensure the stability of the fill light. The LED fill light 4022 is located directly below the transparent acrylic plate 406, which can ensure that the light shines vertically upward, providing sufficient basic light source for hole area inspection. The controller 4023 on the front baffle 404 is electrically connected to the LED fill light 4022. The operator can quickly start and stop the LED fill light 4022 through the control button 4025 on the front of the controller 4023 without having to bend over frequently. If the thickness of the SCF single unit is... For different or varying hole depths, the brightness of the LED supplementary light 4022 can be adjusted by rotating the dimming knob 4026 located on top of the control button 4025 via the controller 4023. This adapts to different inspection scenarios. For example, for thick SCF, the light needs to be brightened to ensure clear penetration of the hole area, while for thin SCF, the brightness should be lowered to avoid glare interference. At the same time, the display screen 4024 embedded in the controller 4023 can display parameters such as the current brightness and working time of the LED supplementary light 4022 in real time, making it convenient for operators to monitor the light source status and avoid affecting inspection accuracy due to improper brightness or equipment malfunction. Overall, the light source achieves "convenient adjustment, stable output, and visible status," effectively solving the problem of unstable light source during manual inspection.

[0026] Specifically, such as Figure 6 As shown, the closed structure 403 includes a fixed sleeve 4031 fixedly connected to the bottom front side of the base frame 401, and a closed cover 4032 is rotatably connected to the inner side of the fixed sleeve 4031.

[0027] Specifically, such as Figure 6 As shown, magnetic pieces 4033 are embedded in both sides of the rear side of the closed cover 4032, and magnetic strips 4034 are embedded in both sides of the front side of the bottom frame 401. The magnetic strips 4034 are magnetically connected to the magnetic pieces 4033.

[0028] In this embodiment: By setting a closed structure 403, the fixing sleeve 4031 at the bottom front of the bottom frame 401 is rotatably connected to the closing cover 4032. The operator can rotate the closing cover 4032 around the fixing sleeve 4031 to open and close the front of the bottom frame 401. Before inspection, the closing cover 4032 can be opened for convenient maintenance or replacement of the LED supplementary light 4022. During inspection, the closing cover 4032 can be closed to prevent external dust and debris from entering the bottom frame 401 and avoid adhering to the LED supplementary light 4022 or the heat dissipation substrate 4021, thus affecting the light source output. To improve heat dissipation and ensure the long-term stable operation of the illumination structure 402, the magnetic sheet 4033 on the back of the sealing cover 4032 is magnetically connected to the magnetic strip 4034 on the front of the bottom frame 401. After closing, it can automatically be attracted and fixed without additional locking clips. It is convenient to operate and can ensure a tight seal. The tight sealing structure 403 can also reduce the light leakage of the LED supplement light 4022 from the front of the bottom frame 401, so that the light can be more concentrated and pass upward through the focusing micro-hole 409 of the transparent acrylic plate 406, further enhancing the illumination intensity of the hole area and improving the clarity of defect identification.

[0029] Specifically, such as Figure 3 As shown, the inner walls of both the test tank 2 and the placement tank 3 are provided with elastic buffer pads 5, which are made of silicone.

[0030] Specifically, such as Figure 2 , Figure 6 As shown, the surface of the inclined transition plate 405 is coated with a Teflon coating, and the inner wall of the bottom frame 401 is bonded with an aluminum foil layer 6.

[0031] In this embodiment: by setting silicone elastic buffer pads 5 on the inner walls of the test tank 2 and the placement tank 3, the collision force between the product and the tank wall can be buffered when the SCF monomer is placed or taken out in a Z-shaped fold, avoiding creases or damage to the SCF edge due to impact. At the same time, the anti-slip properties of the silicone material prevent the product from sliding and shifting in the tank, ensuring neat storage. The Teflon coating on the surface of the inclined transition plate 405 has low friction characteristics. When the SCF monomer slides along the inclined transition plate 405, the friction between the product and the plate surface can be greatly reduced, avoiding scratches on the SCF surface due to friction. At the same time, it ensures that the sliding process is smooth and does not jam, improving the inspection flow efficiency. The aluminum foil layer 6 bonded to the inner wall of the bottom frame 401 has a high reflectivity, which can reflect the light emitted by the LED supplement light 4022 to the direction of the transparent acrylic plate 406, reducing light waste and allowing more light to be concentrated on the SCF hole area, indirectly enhancing the irradiation intensity and helping to improve the accuracy of hole area defect identification.

[0032] Specifically, such as Figure 7 As shown, a storage frame 7 is fixedly connected to the bottom of the base 1, and a storage box 8 is slidably connected inside the storage frame 7.

[0033] Specifically, such as Figure 7As shown, a partition plate 9 is fixedly connected in the middle of the inside of the storage box 8, and a soft sponge pad 10 is glued to the bottom side of the inside of the storage box 8.

[0034] In this embodiment: the storage frame 7 at the bottom of the base 1 provides a fixed mounting carrier for the storage box 8. The storage box 8 is slidably connected to the storage frame 7 via a slide rail, allowing operators to easily push and pull the storage box 8 for convenient tool retrieval. The internal partition 9 of the storage box 8 divides the internal space into independent areas, which can be used to place inspection tools such as magnifying glasses, markers, and defect record sheets separately, preventing tools from being mixed up or lost and improving operational convenience. The soft sponge pad 10 on the bottom side of the storage box 8 has a cushioning and protective function, which can reduce collision damage when tools are placed in (such as preventing the magnifying glass lens from breaking due to impact), and at the same time can fix the position of the tools, preventing the tools from sliding and misaligning when pushing and pulling the storage box 8, ensuring that the tools are in the preset position every time they are used, further improving the efficiency of inspection assistance.

[0035] Working Principle: When using the manual inspection device for folded SCF, the operator first places the Z-shaped folded SCF units to be inspected into the test slot 2 on the left side of the base 1. The silicone elastic buffer pad 5 on the inner wall of the test slot 2 can buffer the impact force when the product is placed in, avoiding creases or damage to the edges of the SCF. At the same time, the anti-slip properties of the silicone prevent the product from sliding or shifting in the slot, ensuring that the products to be inspected are stored neatly without the need for subsequent additional handling. Next, the closed cover 4032 on the front side of the base frame 401 is opened (it can be opened by rotating around the fixing sleeve 4031). The LED fill light 4022 is activated by the control button 4025 on the controller 4023 on the front baffle 404. At this time, the display screen 4024 embedded in the controller 4023 will display the LED fill light in real time. The brightness and working time of the LED fill light 4022 are adjusted by rotating the dimming knob 4026 on the controller 4023, based on the thickness of the SCF unit being inspected or the depth of the aperture area. The controller 4023 adjusts the brightness of the LED fill light 4022—brighter for thicker SCF units to ensure clear penetration into the aperture area, and dimmer for thinner SCF units to avoid glare. Simultaneously, the aluminum foil layer 6 on the inner wall of the bottom frame 401 reflects the light emitted by the LED fill light 4022 towards the transparent acrylic plate 406, reducing light waste and enhancing the illumination intensity of the aperture area. After brightness adjustment, the sealing cover 4032 is closed. The magnetic piece 4033 on its inner side automatically attaches and fixes itself to the magnetic strip 4034 on the front of the bottom frame 401, preventing external dust from entering the bottom frame 401 and affecting the light source output. To minimize light leakage and ensure focused light on the inspection area, the operator removes a single folded SCF from the test slot 2 and pushes it along the left-side inclined transition plate 405 towards the transparent acrylic plate 406. The Teflon coating on the inclined transition plate 405 significantly reduces friction between the product and the plate, preventing scratches on the SCF surface. Simultaneously, the inclined structure guides the product's smooth sliding. Combined with the baffles 404 on the front and rear sides of the top of the bottom frame 401, this prevents the SCF from shifting during sliding, ensuring it accurately lands in the inspection area of ​​the transparent acrylic plate 406. At this time, the light from the LED supplementary light 4022 shines vertically upwards through the transparent acrylic plate 406, forming a directional beam through the focusing micro-hole 409 at the top, precisely targeting the SCF's perforated area. Using the horizontal and vertical scale lines 407 and 408 on the acrylic plate, staff can quickly locate the hole areas on the SCF, compare the scale to determine if the holes are misaligned, and visually identify any blockages or other defects in the hole areas by observing the penetration of the focused beam. They can also simultaneously observe the SCF surface for scratches or foreign objects. During the inspection, the heat dissipation substrate 4021 inside the base frame 401 continuously conducts the heat generated by the LED supplementary light 4022, preventing the light body from aging due to high temperatures and ensuring a continuous and stable output of the light source. After inspection, the qualified SCF unit is slid into the placement groove 3 on the right side of the base 1 along the inclined transition plate 405. The silicone elastic buffer pad 5 on the inner wall of the placement groove 3 also provides protection and anti-slip properties, ensuring that the inspected products are stored in an orderly manner.If tools such as magnifying glasses and markers are needed during the inspection process, the storage box 8 inside the storage frame 7 at the bottom of the base 1 can be pushed or pulled (smoothly sliding via a rail). The dividers 9 inside the storage box 8 categorize the tools and place them in independent areas for easy and quick access. The soft sponge pad 10 on the bottom of the box prevents tool collision damage and also prevents tools from sliding or misaligning during pushing and pulling. The entire process eliminates the need for manual handling and folding of the SCF. Through the synergistic effect of various structures, a complete inspection process is achieved: "orderly product flow - precise light source control - efficient defect identification - convenient tool access." This solves the problems of low efficiency and high missed detection rate in traditional manual inspection and is suitable for the manual inspection needs of small batches and multiple specifications of Z-shaped folded SCFs.

[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
