Description

Technical Field

[0001] The invention belongs to the technical field of visual inspection, and in particular relates to an auxiliary inspection device for products after an isolation film spot coating process. Background Art

[0002] AOI (Automated Optical Inspection) is automatic optical inspection. The slitting machine AOI combined inspection device integrates the AOI inspection system on the basis of the slitting machine. The slitting machine is mainly used to slit wide materials (such as paper, objects to be inspected, magnetic tapes, etc.) into narrow materials. The AOI inspection part uses optical principles to capture the image of the slit product through a camera, and then uses image processing algorithms to analyze the image to detect product size, shape, surface defects and other quality-related parameters.

[0003] Dispensing is a process of precisely applying materials to a specific area. The dispensing machine is used to apply the patch glue to the specified area of ​​the PCB, and the size of the glue dots is controlled by pressure and time. The dispensing AOI equipment obtains the image information of the dispensing area through a high-precision optical imaging system, and then uses image processing algorithms and intelligent recognition technology to analyze and process the image, thereby detecting quality problems in dispensing, such as lack of glue, overflow of glue, leakage of glue, irregular shape of glue dots, uneven glue thickness, etc.

[0004] The AOI inspection assembly needs to perform surface defect inspection on film products during the film winding and unwinding process. During the film transmission process, its surface may be contaminated with dust, fibers and other impurities, which will affect the effect of visual inspection. Therefore, a cleaning process is required to remove these impurities to ensure that the film surface is clean and tidy. For example, some tiny dust particles may be mistaken for defects in the isolation film coating during visual inspection. The cleaning method in the prior art generally uses the form of an air curtain to align the air duct opening with the film surface for dust removal. However, some dust will float and be contaminated on the surface of the tensioning roller after being blown off the film surface. When the tensioning roller is in contact with the film surface, the dust impurities will be pressed on the film surface again, affecting subsequent inspections. In order to prevent dust from being blown by the wind curtain and adhering to the surface of the tensioning roller, some technicians will use vacuuming to directly vacuum the film surface with negative pressure. However, this method is difficult to control the strength of negative pressure vacuuming. For thinner film products, if the negative pressure suction force is too large, the film product will be directly adsorbed and pulled with the film product roll, resulting in tearing of the film product. If the negative pressure suction force is reduced, or a gap is left between the negative pressure source and the film product to prevent the negative pressure source from directly adsorbing the film product, this method will result in some dust being unable to be effectively removed from the surface of the film product. As for the clean room, the equipment for producing thin films is usually large in size. If these equipment are to be placed in the clean room, they need to be specially designed and modified to meet the requirements of the clean room, which will undoubtedly increase the investment cost of the equipment. Moreover, the operation and maintenance of these equipment in the clean room also require more stringent operation and management, further increasing the cost of using the equipment.

[0005] Therefore, an auxiliary inspection device for products after the isolation film dot coating process is designed to solve the technical problems in the prior art that during the transmission of thin film products, negative pressure vacuum directly adsorbs the thin film products, affecting the transmission of thin film products, or it is difficult to effectively adsorb and remove dust on the surface of the thin film products, affecting the subsequent visual inspection effect.

[0030] According to research, the AOI inspection assembly needs to perform surface defect inspection on film products during the film winding and unwinding process. During the film transmission process, its surface may be contaminated with dust, fibers and other impurities, which will affect the visual inspection effect. Therefore, a cleaning process is required to remove these impurities to ensure that the film surface is clean and tidy. For example, some tiny dust particles may be mistaken for defects in the isolation film coating during visual inspection. The cleaning method in the prior art generally uses the form of an air curtain to align the air duct opening with the film surface for dust removal. However, some dust will float and contaminate the surface of the tensioning roller after being blown off the film surface. When the tensioning roller is in contact with the film surface, the dust impurities will be pressed again on the film surface, affecting subsequent inspections. In order to prevent dust from being blown by the wind curtain and adhering to the surface of the tensioning roller, some technicians will use vacuuming to directly vacuum the film surface with negative pressure. However, this method is difficult to control the strength of negative pressure vacuuming. For thinner film products, if the negative pressure suction force is too large, the film product will be directly adsorbed and pulled with the film product roll, resulting in tearing of the film product. If the negative pressure suction force is reduced, or a gap is left between the negative pressure source and the film product to prevent the negative pressure source from directly adsorbing the film product, this method will result in some dust being unable to be effectively removed from the surface of the film product. As for the clean room, the equipment for producing thin films is usually large in size. If these equipment are to be placed in the clean room, they need to be specially designed and modified to meet the requirements of the clean room, which will undoubtedly increase the investment cost of the equipment. Moreover, the operation and maintenance of these equipment in the clean room also require more stringent operation and management, further increasing the cost of using the equipment.

[0031] Based on the above research, an embodiment of the present disclosure provides an auxiliary detection device for products after the isolation film dot coating process. By providing a cleaning mechanism, dust contaminated on the surface of the film is removed during the film transmission process, and dust adhered to the surface of the tensioning roller is adsorbed in real time during the process of the tensioning roller rotating to tension the film, thereby preventing the dust blown off the film from adhering to the surface of the tensioning roller and being pressed against the surface of the film as the tensioning roller rotates, affecting the subsequent visual inspection effect.

[0032] The defects existing in the above solutions are the results obtained by the inventor after practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed by the present invention in this article for the above problems should be the contributions made by the inventor to the present invention during the disclosure process.

[0033] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0034] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0035] In some embodiments, Figure 1 As shown, before starting to inspect the film product for defects, the operator manually passes the film product 2 to be inspected between the two tensioning rollers 51 and connects it to the winding roller 12 in the winding frame 11, and then uses a motor or other driving method to utilize the rotation of the winding roller 12 to drive the film product 2 to be inspected to be transported in the bracket 1, and sets each two mutually parallel pillars 50 as a group, and each group includes two tensioning rollers 51 arranged in parallel up and down. By setting multiple groups, the transmission route of the film product 2 to be inspected is lengthened, providing an effective inspection space for subsequent visual inspection work; Specifically, Figure 2 As shown, a plurality of projection light machines 10 are arranged on the route of the film product 2 to be inspected transmitted in the direction of F3, and are located above the film product 2 to be inspected, for common defect detection such as pinholes, oil stains, black spots, etc. Synchronously, upper and lower smart cameras are arranged on the upper and lower sides of the film product 2 to be inspected, respectively, and first and second fill-light components are arranged corresponding to the upper and lower sides of the film product 2 to be inspected. In the figure, the lower smart camera 30 and the first fill-light component 31 are in a straight line, and the first fill-light component is used to illuminate the film product 2 to be inspected, so that the image taken by the lower smart camera 30 is clear. The working principles of the upper smart camera 40 and the second fill-light component 41 are the same as described above. By synchronously detecting the upper and lower sides of the film product 2 to be inspected, defects such as missing points, few points, and many points on the coating film surface of the film product 2 to be inspected are detected, and missed detection is fully avoided.

[0036] In some embodiments, Figure 3 and Figure 4 As shown, in the process of the winding roller 12 rotating to drive the film product to be inspected to be transmitted, the first driver 521 located on the upper end surface of the sliding cavity 511 on one of the pillars 50 is started, and its output end drives the bidirectional screw 522 to rotate, thereby driving the two sliders 523 that are respectively engaged with the two ends of the bidirectional screw 522 to slide closer to each other, so as to drive the two tensioning rollers 51 to approach each other to increase the clamping force of the film product 2 to be inspected. Since the winding speed of the winding roller 12 is constant, the film product 2 to be inspected being transmitted at this time will be tensioned, so as to avoid wrinkles in the film product 2 to be inspected during the winding process and affect the visual inspection results.

[0037] In some embodiments, Figure 4 and Figure 5 As shown, during the transmission of the film product 2 to be detected, the second driver 535 located on the connecting plate 8 is started, and its output end drives the rotating shaft 537 and a plurality of fan blades 536 fixed on the rotating shaft 537 to rotate, and the blowing direction of the fan blades 536 is toward the film product 2 to be detected during the transmission process, so as to blow off dust and other impurities on its surface to avoid affecting the subsequent detection results; during the sliding process of the upper and lower tensioning rollers 51 to approach each other, the connecting rods 532 set on the two tensioning rollers 51 will be driven to approach each other, and the connecting rods 532 set on the two tensioning rollers 51 will be driven to approach each other. Figure 5 As shown, a long rod is provided inside each of the two tensioning rollers 51, one end of the long rod is fixed to the corresponding slider 523, and the other end is slidably connected to the support 50 on the other side, and the corresponding connecting rod 532 is fixed on the long rod, and the tensioning roller 51 on each long rod is connected to the corresponding long rod bearing. Figure 5 As shown, as the two tensioning rollers 51 slide towards each other, the conductive sheet 533 slides on the surface of the conductive member 531, and both are connected in series with the second driver 535 through the wire 534. The conductive member 531 is preferably a resistor. At this time, as the conductive sheet 533 slides, the resistance in the circuit where the second driver 535 is located decreases, that is, at this time, the output power of the second driver 535 increases, and the rotation speed of the fan blades increases, thereby improving the efficiency of blowing off dust on the surface of the tensioned film product 2 to be inspected. When the film product 2 to be inspected does not need to be tensioned, the resistance of the circuit where the second driver 535 is located increases, thereby reducing the rotation speed of the fan blades, thereby preventing the film product 2 to be inspected that is not in a tensioned state from being blown by excessive wind speed and actively generating wrinkles that affect the detection results.

[0038] In some embodiments, through the combined detection of a transmitted light machine and upper and lower smart cameras, different spot coating process detections can be met, such as single-sided spot coating, double-sided spot coating, ceramic spot coating, and base film spot coating, etc. When the above-mentioned spot coating processes are inspected after completion, the image contrast is inconsistent. At this time, the operator improves the image contrast by adjusting the lighting angle of each fill light toward the thin film product to be inspected to improve the detection efficiency.

[0039] In some embodiments, Figure 6 As shown, in order to prevent dust on the surface of the film product 2 to be inspected or dust on the surface of the tensioning roller 51 from affecting the results of visual inspection, a cleaning mechanism 6 is provided on a pair of tensioning rollers 51 that first come into contact with the film product 2 to be inspected, and an external positive pressure air source (preferably a compressed air system) is connected to the air inlet pipe 62. The positive pressure airflow passes through the air inlet pipe 62 and is blown to the surface of the film product 2 to be inspected through the air flow plate 60 to remove dust on the surface of the film product 2 to be inspected.

[0040] In some embodiments, Figure 7 As shown, the positive pressure airflow is blown along the vertical airflow cavity 600a in the T-shaped airflow cavity 600 to the surface of the film product 2 to be detected for dust removal. At the same time, the horizontal airflow cavity 600b in the T-shaped airflow cavity 600 will passively generate negative pressure suction. At this time, when the surface of the tensioning roller 51 close to the airflow plate 60 rotates through the horizontal airflow cavity 600b, the dust adhered to the surface of the tensioning roller 51 will be sucked into the horizontal airflow cavity 600b and intercepted by the filter 601, so as to remove the dust on the surface of the tensioning roller 51 and prevent the dust from being pressed on the surface of the film product 2 to be detected as the tensioning roller 51 rotates. The exhaust pipe 65 is connected to an external negative pressure gas source (preferably a vacuum pump), and the gas in the hollow tube 63 is extracted through the exhaust pipe 65 to generate negative pressure in the hollow tube 63, that is, negative pressure is formed in the adsorption chamber 64 connected to each air inlet hole 630. As the tensioning roller 51 rotates, when the adsorption chamber 64 contacts the surface of the film product 2 to be detected, the film product 2 to be detected is adsorbed and driven to move to avoid slipping. When the adsorption chamber 64 rotates to be connected to the horizontal airflow chamber 600b, it is only necessary to control the negative pressure suction force in the adsorption chamber 64 to be greater than the negative pressure suction force generated by the vertical airflow chamber 600a on the horizontal airflow chamber 600b to absorb the dust intercepted by the filter 601. The dust enters the hollow tube 63 through the air inlet hole 630 and is finally discharged and collected by the exhaust pipe 65.
