Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0078] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0079] In the description of this specification, the description with reference to the terms "embodiment", "specific embodiment", "example", etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0080] It should be noted that the terms "first", "second", etc. in the specification and claims of this application and the above drawings are used to distinguish different objects rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0081] See also Figure 1 , Figure 1 It is a schematic diagram of a coating product 1 provided in an embodiment of the present application.

[0082] In this embodiment, the coating product 1 includes a substrate 10a and a coating 10b, and the coating 10b is located on the surface of the substrate 10a. Among them, the substrate 10a can be a glass substrate made of glass. The shape of the substrate 10a is a quadrilateral. Exemplarily, the size of the substrate 10a can be 750mm×650mm, 630mm×585mm, 210mm×195mm or 250mm×220mm, etc., and the present application does not specifically limit the size of the substrate 10a. Specifically, the substrate 10a includes a first surface and a second surface disposed opposite to each other. The first surface includes a coating area 11 and a marking area 12, the coating area 11 is located in the middle area of ​​the first surface, and the marking area 12 is located in the edge area of ​​the first surface and is arranged around the coating area 11.

[0083] In this embodiment, the shape of the coating area 11 is a quadrilateral. The center of the coating area 11 coincides with the center of the first surface, and the four sides of the coating area 11 are respectively parallel to the four sides of the first surface. It should be noted that in some other embodiments, the shape of the coating area 11 can also be circular, triangular or irregular, etc., and the present application does not specifically limit the shape of the coating area 11.

[0084] The coating 10b is located on the first surface of the substrate 10a. The coating 10b can be formed on the first surface by coating a conductive silver paste. Specifically, the coating 10b is located in the coating area 11 of the first surface. It should be noted that during the production process, the quality of the coating 10b in the coating product 1 is related to the electrical properties of the final product, so it is necessary to perform a quality inspection on the coating 10b of the coating product 1 before proceeding to the next production process.

[0085] It should be understood that in the existing production process, the coating detection process is generally carried out after the drying process, that is, after the conductive silver paste of the coating 10b is completely in a solid state. In the embodiment of the present application, the coating detection process is set between the coating process and the drying process. At this time, the conductive silver paste of the coating 10b may be in a solid state or a semi-solid state, that is, the coating 10b of the coated product 1 can be directly measured after the coating process, and the abnormal products in the production process can be timely controlled before the drying process, so that when the quality of the conductive silver paste of the coating 10b is unqualified, the defective products can be eliminated in time, the drying process of the defective products can be reduced, the cost can be saved, and the production efficiency can be improved.

[0086] In addition, the coating product 1 is also provided with an alignment mark A and an identity mark B. Specifically, the alignment mark A and the identity mark B are both arranged in the marking area 12 to prevent the alignment mark A and the identity mark B from affecting the quality of the coating 10b. In the present embodiment, there are four alignment marks A, and the four alignment marks A are respectively arranged at the four corners of the marking area 12. The identity mark B is arranged on one side of the marking area 12. Among them, the identity mark B is located between the two alignment marks A, and is spaced apart from the two alignment marks A. Among them, the alignment mark A can be any text or pattern such as a cross or a dot, so that each device in the subsequent process flow can position the coating product 1, and the identity mark B can be a certain text or pattern such as a barcode or a QR code, so that each device in the subsequent process flow can read the product code and other related product information of the coating product 1.

[0087] Please also read Figure 2 and Figure 3 . Figure 2 It is a structural schematic diagram of a coating detection device 2 provided in the present application. Figure 3 yes Figure 2 The plan structure diagram of the coating detection device 2 is shown.

[0088] The coating inspection device 2 is used to inspect the quality of the coating 10b in the coated product 1. It should be noted that since there are a variety of coated products 1 of different sizes, and the sizes of the coated products 1 in the same batch are the same. When inspecting the quality of the coating 10b in the same batch of coated products 1, the coating inspection device 2 can adaptively inspect the quality of the coating 10b in the batch of coated products 1 according to a preset program.

[0089] Next, for the convenience of description, the length direction of the coating detection device 2 is defined as the X-axis direction, the width direction of the coating detection device 2 is defined as the Y-axis direction, and the height direction of the coating detection device 2 is defined as the Z-axis direction. The X-axis direction, the Y-axis direction and the Z-axis direction are perpendicular to each other.

[0090] It should be understood that the product is produced in an assembly line manner. In the embodiment of the present application, the coating detection process is arranged between the coating process and the drying process, that is, the coating detection equipment 2 is located downstream of the coater and upstream of the dryer.

[0091] According to the different detection processes of the coating detection device 2, the coating detection device 2 can be roughly divided into 8 working areas, which are the first area 21, the second area 22, the third area 23, the fourth area 24, the fifth area 25, the sixth area 26, the seventh area 27 and the eighth area 28. The first area 21, the second area 22, the third area 23 and the fourth area 24 are arranged in sequence along the positive direction of the X axis, the fourth area 24, the fifth area 25 and the sixth area 26 are arranged in sequence along the positive direction of the Y axis, and the fifth area 25, the sixth area 26, the seventh area 27 and the eighth area 28 are arranged in sequence along the negative direction of the X axis. The third area 23 and the seventh area 27 are arranged in sequence along the positive direction of the Y axis, and the first area 21 and the second area 22 can be arranged in sequence with the eighth area 28 along the positive direction of the Y axis.

[0092] The coating detection device 2 can complete the automatic handling of the coating product 1 in the first area 21, the second area 22, the third area 23, the fourth area 24, the fifth area 25, the sixth area 26, the seventh area 27 and the eighth area 28 according to the preset scheme. Specifically, the principle of formulating the preset scheme is that the area of ​​the first surface of the coating product 1 that the coating detection device 2 can touch accounts for less than or equal to 10% of the area of ​​the first surface of the coating product 1, and the coating detection device 2 cannot have rolling friction relative to the second surface of the coating product 1. Based on this, preset schemes are designed for different types of coating products 1, so that the coating detection device 2 can complete the automatic handling process of the coating product 1 in the first area 21, the second area 22, the third area 23, the fourth area 24, the fifth area 25, the sixth area 26, the seventh area 27 and the eighth area 28, and complete the appearance inspection, position accuracy inspection and film thickness inspection of the coating 10b.

[0093] In this embodiment, the coating detection device 2 includes a housing (not shown), a machine (not shown), a first feeding mechanism 31, an appearance detection mechanism 32, a second feeding mechanism 33, a composite detection mechanism 34, a discharging mechanism 36, a re-judgment mechanism 37, a conveying mechanism 35, a cache mechanism 38, a discharging mechanism 39 and a processor. The machine, the first feeding mechanism 31, the appearance detection mechanism 32, the second feeding mechanism 33, the composite detection mechanism 34, the conveying mechanism 35, the discharging mechanism 36, the re-judgment mechanism 37, the cache mechanism 38, and the discharging mechanism 39 are all located inside the housing. Among them, the housing can play the role of dust prevention and protection, so as to extend the service life of the coating detection device 2 and ensure the reliability of the coating detection device 2. It should be noted that the embodiment of the present application does not specifically limit the structure of the housing, and the structure of the housing can be designed according to the needs.

[0094] The first feeding mechanism 31, the appearance inspection mechanism 32, the second feeding mechanism 33, the composite inspection mechanism 34, the conveying mechanism 35, the discharging mechanism 36, the re-judgment mechanism 37, the buffer mechanism 38, and the unloading mechanism 39 are all installed on the top side of the machine. The processor is electrically connected to the first feeding mechanism 31, the appearance inspection mechanism 32, the second feeding mechanism 33, the composite inspection mechanism 34, the conveying mechanism 35, the discharging mechanism 36, the re-judgment mechanism 37, the buffer mechanism 38, and the unloading mechanism 39. Among them, the processor is used to control the automatic handling process of the coating inspection equipment, run and store the data processing system, that is, it can send operation instructions to each mechanism so that each mechanism performs corresponding operations.

[0095] It should be noted that the directional terms such as "top" and "bottom" used in the present embodiment to describe the coating inspection device 2 are mainly based on the coating inspection device 2 attached. Figure 2 The display orientation is explained in detail, with the positive direction of the Z axis being the "top" and the negative direction of the Z axis being the "bottom", which does not constitute a limitation on the orientation of the coating inspection device 2 in actual application scenarios.

[0096] See also Figure 1 , Figure 2 and Figure 4 . Figure 4 yes Figure 2 A schematic structural diagram of the first feeding mechanism 31 in the coating inspection device 2 is shown.

[0097] The first loading mechanism 31 includes a bearing assembly 311, a first support frame 312, a first slide rail 313, a first slider 314, a transfer arm 315, a lifting mechanism 316 and a first driving member (not shown). The transfer arm 315, the lifting mechanism 316 and the first driving member are all electrically connected to the processor, and the transfer arm 315, the lifting mechanism 316 and the first driving member can all work according to the instructions of the processor.

[0098] The bearing assembly 311 is located in the first area 21 and is used to bear the coated product 1. In this embodiment, the bearing assembly 311 includes two mounting seats 3114, two brackets 3111, two bearing members 3112 and four stoppers 3113. The two mounting seats 3114 are both mounted on the top surface of the machine, and the two brackets 3111 are respectively mounted on the top surfaces of the two mounting seats 3114 and can slide relative to the mounting seats 3114 along the Y-axis direction. Along the Y-axis direction, the two mounting seats 3114 are spaced apart and arranged opposite to each other, and the two brackets 3111 are spaced apart and arranged opposite to each other.

[0099] Each carrier 3112 is installed on a bracket 3111. Specifically, each carrier 3112 is installed on the top surface of a bracket 3111. The carrier 3112 has a bearing surface, and the bearing surface can bear the coated product 1. The bearing surfaces of the two carriers 3112 bear the coated product 1 together. At this time, the second surface of the substrate 10a in the coated product 1 contacts the bearing surfaces of the two carriers 3112.

[0100] Every two limit members 3113 are installed on a bracket 3111. Specifically, along the X-axis direction, every two limit members 3113 are installed on the top surface of a bracket 3111. Every two limit members 3113 are located on opposite sides of a support member 3112, and are spaced apart from the support member 3112. When the bearing surfaces of the two support members 3112 jointly carry the coating product 1, each bracket 3111 drives two limit members 3113 to slide relative to a mounting seat 3114, and the two brackets 3111 are relatively close, and the four limit members 3113 work together to clamp the coating product 1, and adjust the coating product 1 to a preset initial position of the data processing system. It can be understood that the coating products 1 of the same batch have the same size parameters, so the coating products 1 of the same batch have the same initial position.

[0101] The first support frame 312 is installed on the top surface of the machine, and the first slide rail 313 is installed on the top surface of the first support frame 312. Specifically, the first support frame 312 and the first slide rail 313 are both located between the two mounting seats 3114, and are spaced apart from the two mounting seats 3114. In this embodiment, the first support frame 312 and the first slide rail 313 both extend along the X-axis direction. Part of the first support frame 312 and part of the first slide rail 313 are located in the first area 21, part of the first support frame 312 and part of the first slide rail 312 are located in the second area 22, and part of the first support frame 312 and part of the first slide rail 312 are located in the third area 23.

[0102] The first slider 314 is slidably mounted on the first slide rail 313, and can slide on the first slide rail 313 along the X-axis direction under the action of the first driving member to shuttle between the first area 21, the second area 22 and the third area 23. The lifting mechanism 316 is installed on the top surface of the first slider 314, and can slide on the first slide rail 313 along the X-axis direction under the drive of the first slider 314.

[0103] The transfer arm 315 is installed on the top side of the lifting mechanism 316, and can move along the Z-axis direction driven by the lifting mechanism 316. The transfer arm 315 is used to transport the coated product 1 carried by the carrying component 311 to the second loading mechanism 33. Among them, the transfer arm 315 includes a plurality of first suction cups 3151, and the plurality of first suction cups 3151 can firmly adsorb the coated product 1 after the initial position is calibrated on the top side of the transfer arm 315 through vacuum suction. The coated product 1 can not only move along the Z-axis direction following the lifting mechanism 316 driven by the transfer arm 315, but also slide along the X-axis direction on the first slide rail 313 following the first slider 314 driven by the transfer arm 315 and the lifting mechanism 316.

[0104] Specifically, the coating product 1 formed after the coating process is located in the first area 21, and is carried on the bearing surfaces of the two bearing members 3112 in the bearing assembly 311, and the four limiting members 3113 limit the coating product 1 in the preset initial position. Subsequently, driven by the first driving member, the first slider 314 drives the lifting mechanism 316 and the transfer arm 315 to move along the X-axis direction on the first slide rail 313 to between the two mounting seats 3114 in the bearing assembly 311, and is located below the coating product 1. Thereafter, the first suction cup 3151 of the transfer arm 315 vacuum absorbs the coating product 1 through vacuum suction. At this time, the first suction cup 3151 is vacuum-absorbed on the second surface of the substrate 10a in the coating product 1.

[0105] Then, each bracket 3111 drives two stoppers 3113 to slide relative to a mounting seat 3114, and the two brackets 3111 move away from each other, and the four stoppers 3113 release the coated product 1. Subsequently, the lifting mechanism 316 drives the transfer arm 315 to move along the positive direction of the Z axis, so that the coated product 1 is separated from the bearing assembly 311 and is higher than the bearing surface of the bearing member 3112. Finally, the first slider 314, driven by the first driving member, drives the lifting mechanism 316, the transfer arm 315 and the coated product 1 to slide along the X axis on the first slide rail 313 to leave the first area 21 and enter the second area 22 and the third area 23 in turn. Thereafter, the coating detection device 2 can detect the coating 10b of the coated product 1.

[0106] Please also read Figure 5 . Figure 5 yes Figure 2 A schematic structural diagram of the appearance detection mechanism 32 in the coating detection device 2 is shown.

[0107] The appearance inspection mechanism 32 is located on one side of the bearing assembly 311 and in the second area 22. The appearance inspection mechanism 32 is used to inspect the appearance of the coating 10b of the coated product 1. The first slider 314 drives the lifting mechanism 316, the transfer arm 315 and the coated product 1 to slide along the X-axis direction on the first slide rail 313 to leave the first area 21 and enter the third area 23. The coated product 1 will pass through the second area 22. At this time, the appearance inspection mechanism 32 can dynamically shoot the appearance of the coating 10b to achieve appearance inspection of the coating 10b of the coated product 1.

[0108] In this embodiment, the appearance detection mechanism 32 includes a bracket 321, a camera group 322 and a light source group 323. The camera group 322 and the light source group 323 are electrically connected to the processor and can work according to the instructions of the processor. The bracket 321 is installed on the top surface of the machine and spans the first support frame 312 and the first slide rail 313 along the Y-axis direction. The camera group 322 is installed on the top side of the bracket 321. The light source group 323 is installed on the bottom side of the camera group 322 and is arranged opposite to the first support frame 312 and the first slide rail 313.

[0109] In this embodiment, the bracket 321 includes two side panels 3211 and a top panel 3212. Along the Y-axis direction, the two side panels 3211 are spaced apart and arranged opposite to each other. The top panel 3212 is located on the top side of the two side panels 3211 and is connected between the two side panels 3211. Specifically, the two side panels 3211 are both installed on the top surface of the machine and are respectively located on opposite sides of the first support frame 312 and the first slide rail 313. Among them, the camera group 322 is installed on the top surface of the top panel 3212, and the light source group 323 is located between the two side panels 3211.

[0110] In this embodiment, the camera group 322 is a device capable of photographing and detecting the appearance defects of the coating area 11, and the light source group 323 can provide a coaxial light source for the camera group 322 to photograph, thereby improving the detection accuracy of the appearance detection mechanism 32. The camera group 322 is used to photograph the coating 10b and upload the photographed data to the data processing system. Specifically, the camera group 322 can photograph the appearance defects of the coating 10b of the coating product 1 on the coating area 11, and upload the actual photos to the data processing system. The data processing system will compare the actual photos with the preset photos, and finally analyze whether the appearance of the coating 10b of the coating product 1 has defects to obtain whether the appearance inspection result of the coating 10b is qualified, and promptly enter the conclusion of whether the appearance inspection result of the coating product 1 is qualified into the system.

[0111] It should be noted that the appearance defects existing in the coating area 11 include but are not limited to scratches, missing, uneven coating 10b, etc. Before each batch of coating products 1 is fed to the first feeding mechanism 31 of the coating inspection device 2, one or more coating products 1 need to be sampled in the batch to judge whether the appearance of the coating 10b of the sampled coating products 1 meets the standard, and determine the main types of defects. Based on this, before the coating inspection device 2 starts working, the defect types and related information to be detected by the appearance inspection mechanism 32 are preset.

The two appearance slide rails 322b are both bar-shaped and mounted on the top surface of the mounting seat 322a. Along the X-axis direction, the two appearance slide rails 322b are parallel and spaced apart. Among them, the two appearance slide rails 322b extend in the same direction as the mounting seat 322a. Each of the two appearance sliders 322c is slidably mounted on an appearance slide rail 322b and can reciprocate along the Y-axis direction along the appearance slide rail 322b.

Two camera slide rails 322g are installed on the left side of the camera support frame 322f and are spaced apart along the Y axis. Each camera slide rail 322g extends along the Z axis.

[0116] It should be noted that the directional terms such as "left" and "right" used in the description of the appearance detection mechanism 32 in the embodiment of the present application are mainly based on the appearance detection mechanism 32 in the attached Figure 6 The display orientation is explained in detail, with the positive direction of the X-axis being "right" and the negative direction of the X-axis being "left", which does not constitute a limitation on the orientation of the appearance detection mechanism 32 in actual application scenarios.

Specifically, the two camera sliders 322h are slidably mounted on the camera slide rail 322g, and the two camera sliders 322h can slide along the Z-axis direction on the two camera slide rails 322g, respectively, thereby driving the first CCD camera support plate 332m to slide along the Z-axis direction. The first camera group 322p is installed on the left side of the first CCD camera support plate 322m, and can slide along the Z-axis with the first CCD camera support plate 322m. The camera driving member 322i can drive the first CCD camera support plate 322m to slide along the Z-axis direction, thereby driving the two camera sliders 322h and the first camera group 322p to slide relative to the two camera slide rails 322g along the Z-axis direction.

[0118] In this embodiment, the first CCD camera support plate 322m is provided with a first scale line 3221a and a first slide groove 3222a. The first scale line 3221a is located on the top surface of the first CCD camera support frame 322m, marking the position of the first camera group 322p in the Y-axis direction. The opening of the first slide groove 3222a is located on the left side of the first CCD camera support frame 3222m. The first slide groove 3222a is provided with a long strip slide groove and extends along the Y-axis direction.

[0119] It should be noted that the present application does not make any specific requirements on the numerical range of the first scale line 3221a, as long as it can adaptably enable the first camera group 322p to detect the coating area 11 of the entire coated product 1 in actual production.

[0120] The first camera group 322p is slidably mounted in the first slide groove 3222a, and can slide in the first slide groove 3222a along the Y-axis direction. Specifically, the first camera group 322p includes three first CCD cameras 3223, and the three first CCD cameras 3223 can slide relatively independently in the first slide groove 3222a along the Y-axis direction. It should be noted that in some other embodiments, the first camera group 322p can also include one, two, four, etc. first CCD cameras 3223, and the present application does not specifically limit the number of first CCD cameras 3223 included in the first camera group 322p, and the number of second CCD cameras 3224 included in the second camera group 322q.

[0121] See also Figure 8 , Figure 8 yes Figure 6 A schematic structural diagram of the first CCD camera 3223 in the camera group 322 is shown.

[0122] In this embodiment, the three first CCD cameras 3223 have the same structure. The first CCD camera 3223 includes a first camera adjustment base plate 3223a, a first pointer 3223b, a first camera scale plate 3223c, a first adjustment fixing plate 3223d, a first positioning member 3223e, a first rotation fine adjustment mechanism 3223f, and a first single-line camera 3223g.

The first adjustment fixing plate 3223d is mounted on the front surface of the first camera scale plate 3223c through the first positioning member 3223e. The first rotation fine-tuning mechanism 3223f is mounted on the front surface of the first adjustment fixing plate 3223d. At the same time, the first single-line camera 3223g is mounted on the first rotation fine-tuning mechanism 3223f, and can be driven by the first rotation fine-tuning mechanism 3223f to rotate relative to the first adjustment fixing plate 3223d to fine-tune the angle of the first single-line camera 3223g relative to the first adjustment fixing plate 3223d.

[0124] It should be noted that the directional terms such as "front" and "rear" used in the description of the appearance detection mechanism 32 in the embodiment of the present application are mainly based on the appearance detection mechanism 32 in the attached Figure 6 The display orientation is explained in detail, with the positive direction of the Y-axis being “rear” and the negative direction of the Y-axis being “front”, which does not constitute a limitation on the orientation of the appearance detection mechanism 32 in the actual application scenario.

Specifically, there are multiple positioning holes, and the multiple positioning holes are located at the top of the first camera scale plate 3223c and are arranged in an arc shape at intervals.

The arc formed by the arrangement of the multiple positioning holes and the arc formed by the scale lines are concentrically arranged.

[0126] A pointer is provided at the bottom of the first adjustment fixing plate 3223d. When the first positioning member 3223e is installed in different positioning holes, the first adjustment fixing plate 3223d can be rotated to different angles relative to the first camera scale plate 3223c, so that the first single-line camera 3223g can be adjusted within a certain arc range through the positioning holes to complete the detection of different defect types. At this time, the position indicated by the pointer on the scale line is the rotation angle of the first adjustment fixing plate 3223d relative to the first camera scale plate 3223c, thereby realizing the visualization of the adjustment angle of the first single-line camera 3223g.

[0127] It should be noted that the present application does not specifically limit the numerical range of the scale lines of the first camera scale plate 3223c. It can be any integer from 0 to 10, or any integer from -10 to 5. The numerical range can be determined according to actual production needs.

[0128] Please refer to Figure 7 The two side rails 322j are installed on the right side of the camera support frame 322f and are spaced apart along the Y-axis direction. Each pair of side rails 322j extends along the Z-axis direction.

[0129] The two opposite side sliders 322k are both installed on the left side of the second CCD camera support plate 322n and are spaced apart along the Y-axis direction. Specifically, the two opposite side sliders 322k are slidably mounted on the opposite side rails 322j, and the two opposite side sliders 322k can slide along the Z-axis direction on the two opposite side rails 322j, respectively, thereby driving the second CCD camera support plate 322n to slide along the Z-axis direction.

The opening of the second slide groove 3222b is located on the right side of the second CCD camera support frame 3222n. The second slide groove 3222b is provided with a long strip slide groove and extends along the Y-axis direction.

[0131] It should be noted that the present application does not make any specific requirements on the numerical range of the second scale line 3221b, as long as it can adaptably enable the second camera group 322q to detect the coating area 11 of the entire coated product 1 in actual production.

[0132] The second camera group 322q is slidably mounted on the second slide groove 3222b, and can slide in the second slide groove 3222b along the Y-axis direction. Among them, the first camera group 322p and the second camera group 322q are both located on the top side of the first slide rail 313. The second camera group 322q is located on the side of the first camera group 322p facing the composite detection mechanism 34.

Specifically, the second camera group 322q includes three second CCD cameras 3224, and the three second CCD cameras 3224 can slide relatively independently in the second slide groove 3222b along the Y-axis direction. It should be noted that in some other embodiments, the second camera group 322q can also include one, two, four, etc. second CCD cameras 3224, and the present application does not specifically limit the number of second CCD cameras 3224 included in the second camera group 322q and the number of second CCD cameras 3224 included in the second camera group 322q.

[0133] Please also read Fig. 9 , Fig. 9 yes Figure 7A schematic structural diagram of the second CCD camera 3224 in the camera group 322 is shown.

[0136] In addition, the second camera scale plate 3224c is provided with positioning holes and scale lines. Specifically, there are multiple positioning holes, and the multiple positioning holes are located at the top of the second camera scale plate 3224c and are arranged in an arc shape at intervals. The scale lines are located at the bottom side of the second camera scale plate 3224c and are in an arc shape. The arc formed by the arrangement of the multiple positioning holes and the arc formed by the scale lines are concentrically arranged.

[0137] A pointer is provided at the bottom of the second adjustment fixing plate 3224d. When the second positioning member 3224e is installed in different positioning holes, the second adjustment fixing plate 3224d can be rotated to different angles relative to the second camera scale plate 3224c, so that the second single-line camera 3224g can be adjusted within a certain arc range through the positioning holes to complete the detection of different defect types. At this time, the position indicated by the pointer on the scale line is the rotation angle of the second adjustment fixing plate 3224d relative to the second camera scale plate 3224c, thereby realizing the visualization of the adjustment angle of the second single-line camera 3224g.

[0138] It should be noted that the present application does not specifically limit the numerical range of the scale lines of the second camera scale plate 3224c. It can be any integer from 0 to 10, or any integer from -10 to 5. The numerical range can be determined according to actual production needs.

Among them, the three first CCD cameras 3223 are all used to detect the first appearance defect A, and the three second CCD cameras 3224 are all used to detect the second appearance defect B. The defect types of the first appearance defect A and the second appearance defect B are different. It should be noted that the specific types of the appearance defect type A and the appearance defect type B detected by the first camera group 322p and the second camera group 322q can be designed according to the needs. In some other embodiments, the specific types of the first appearance defect A and the second appearance defect B may also be the same.

[0140] See also Figure 5 , Fig.10 and Fig.11 . Fig.10 yes Figure 5 A schematic structural diagram of the light source group 323 in the appearance detection mechanism 32 is shown. Fig.11 yes Fig.10 The structure diagram of the light source group 323 shown is shown at another angle.

[0141] The light source group 323 includes a first mounting bracket 3231, a first angle adjustment member 3232, a first coaxial light source 3233, a second mounting bracket 3234, a second angle adjustment member 3235, and a second coaxial light source 3236. The first mounting bracket 3231, the first angle adjustment member 3232, the first coaxial light source 3233, the second mounting bracket 3234, the second angle adjustment member 3235, and the second coaxial light source 3236 are all mounted on the bottom side of the mounting seat 322a in the camera group 322.

[0142] There are two first angle adjustment members 3232. Along the Y-axis direction, the two first angle adjustment members 3232 are respectively installed at opposite ends of the first mounting frame 3231, and both can rotate relative to the first mounting frame 3231. The first coaxial light source 3233 is located at the bottom side of the first mounting frame 3231, and is fixedly connected between the two first angle adjustment members 3232. Specifically, one end of each first angle adjustment member 3232 is installed on the first mounting frame 3231, and the other end of the first angle adjustment member 3232 is fixedly connected to the first coaxial light source 3233. At this time, the first coaxial light source 3233 can be driven by the two first angle adjustment members 3232 to rotate relative to the first mounting frame 3231, thereby adjusting the inclination angle of the first coaxial light source 3233.

[0143] In this embodiment, the first mounting frame 3231 is provided with a first light source positioning hole 3231a and a first light source scale line 3231b. Specifically, the opening of the first light source positioning hole 3231a is located on the front surface of the first mounting frame 3231, and the first light source scale line 3231b is located on the front surface of the first mounting frame 3231. Among them, the first light source positioning hole 3231a and the first light source scale line 3231b are both arc-shaped, and the arcs of the first light source positioning hole 3231a and the first light source scale line 3231b are concentrically arranged to achieve the correspondence between the first light source positioning hole 3231a and the first light source scale line 3231b.

[0144] The first angle adjustment member 3232 is installed on the first mounting frame 3231 through the first light source positioning hole 3231a. The first angle adjustment member 3232 can be fixed at different positions of the first light source positioning hole 3231a, so that the relative rotation angle between the first angle adjustment member 3232 and the first mounting frame 3231 can be adjusted within a certain arc range, so that the first coaxial light source 3233 can adjust the irradiation angle within a certain arc range. At this time, the first light source scale line 3231b can accurately reflect the relative rotation angle of the first angle adjustment member 3232 relative to the first mounting frame 3231, and then identify the angle adjusted by the first coaxial light source 3233 relative to the first mounting frame 3231, so that the adjustment angle of the first coaxial light source 3233 can be visualized, and the first camera group 322p can provide corresponding light irradiation requirements for detecting different defect types.

[0145] It should be noted that the present application does not specifically limit the numerical range of the first light source scale line 3231b of the first mounting frame 3231, which can be any integer from 0 to 10, or any integer from -10 to 20, and its numerical range can be determined according to actual production needs.

[0146] The first angle adjustment member 3232 includes a first light source fixing plate 3232a, a first light source positioning member 3232b and a first scale pointer 3232c. The first light source positioning member 3232b passes through the first light source positioning hole 3231a to mount the first light source fixing plate 3232a on the first mounting frame 3231, and the first scale pointer 3232c is fixedly connected to the first light source fixing plate 3232a and is located on the front side of the first mounting frame 3231, and cooperates with the first light source scale line 3231b to indicate the rotation angle of the first angle adjustment member 3232 relative to the first mounting frame 3231.

[0147] The first coaxial light source 3233 is fixedly connected between the first light source fixing plates 3232a of the two first angle adjustment members 3232, and can move synchronously with the two angle adjustment members 3232 under the drive of the two first light source fixing plates 3232a. Among them, the first coaxial light source 3233 is located between the first camera group 322p and the first slide rail 313. The first coaxial light source 3233 can be driven by the first light source fixing plate 3232a, and the position of the first light source positioning member 3232b on the first mounting frame 3231 changes, and rotates relative to the first mounting frame 3231 to adjust the angle at which the first coaxial light source 3233 can irradiate the coated product 1. It should be understood that the first light source positioning member 3232b is a component that can be installed on the first mounting frame 3231 and can change position relative to the first mounting frame 3231.

[0148] The first coaxial light source 3233 is provided with a light-through slot 3233a, and the opening of the light-through slot 3233a is located on the top surface of the first coaxial light source 3233. When the first camera group 322p takes pictures of the appearance of the coated product 1, the three first CCD cameras 3223 of the first camera group 322p all take pictures of the appearance of the coated product 1 through the light-through slot 3233a. Specifically, the light-through slot 3233a is provided with a reflection light path, and when the light reflected from the first surface of the coated product 1 passes through the light-through slot 3233a, the reflected light in different directions can be uniformly converged into the lens range of the three first CCD cameras 3223, and when the coated product 1 passes under the three first CCD cameras 3223, it can be received by the three first CCD cameras 3223, so that the three first CCD cameras 3223 take pictures of the appearance of the coated product 1 through the light-through slot 3233a, and complete the detection of the appearance defect type A. Thereby, the imaging of the three first CCD cameras 3223 is clearer, and the accuracy of the detection result is improved.

[0149] The second mounting frame 3234 is provided with a second light source positioning hole 3234a and a second light source scale line 3234b. Specifically, the opening of the second light source positioning hole 3234a is located on the front surface of the second mounting frame 3234, and the second light source scale line 3234b is located on the front surface of the second mounting frame 3234. The second light source positioning hole 3234a and the second light source scale line 3234b are both in arc shape, and the arc shape of the second light source positioning hole 3234a and the second light source scale line 3234b are concentrically arranged to achieve the correspondence between the second light source positioning hole 3234a and the second light source scale line 3234b.

[0150] The second angle adjustment member 3235 is installed on the second mounting frame 3234 through the second light source positioning hole 3234a. The second angle adjustment member 3235 can be fixed at different positions of the second light source positioning hole 3234a, so that the relative rotation angle between the second angle adjustment member 3235 and the second mounting frame 3234 can be adjusted within a certain arc range, so that the second coaxial light source 3236 can adjust the irradiation angle within a certain arc range. At this time, the second light source scale line 3234b can accurately reflect the relative rotation angle of the second angle adjustment member 3235 relative to the second mounting frame 3234, and then mark the angle adjusted by the second coaxial light source 3236 relative to the second mounting frame 3234, so that the adjustment angle of the second coaxial light source 3236 can be visualized, and the corresponding light irradiation requirements are provided for the second camera group 322q to detect different defect types.

[0151] It should be noted that the present application does not specifically limit the numerical range of the second light source scale line 3234b of the second mounting frame 3234. It can be any integer from 0 to 10, or any integer from -10 to 20. Its numerical range can be determined according to actual production needs.

[0152] The second angle adjustment member 3235 includes a second light source fixing plate 3235a, a second light source positioning member 3235b, and a second scale pointer 3235c. The second light source positioning member 3235b passes through the second light source positioning hole 3234a to mount the second light source fixing plate 3235a on the second mounting frame 3234. The second scale pointer 3235c is fixedly connected to the second light source fixing plate 3235a and is located on the front side of the second mounting frame 3234, and cooperates with the second light source scale line 3234b to indicate the rotation angle of the second angle adjustment member 3235 relative to the second mounting frame 3234.

[0153] The second coaxial light source 3236 is fixedly connected between the second light source fixing plates 3235a of the two second angle adjustment members 3235, and can move synchronously with the two angle adjustment members 3232 under the drive of the two second light source fixing plates 3235a. Among them, the second coaxial light source 3236 is located between the second camera group 322q and the first slide rail 313. The second coaxial light source 3236 can be driven by the second light source fixing plate 3235a, and the position of the second light source positioning member 3235b on the second mounting frame 3234 changes, and rotates relative to the second mounting frame 3234 to adjust the angle at which the second coaxial light source 3236 can irradiate the coated product 1. It should be understood that the second light source positioning member 3235b is a component that can be installed on the second mounting frame 3234 and can change position relative to the second mounting frame 3234.

[0154] When the second camera group 322q takes a picture of the appearance of the coated product 1, the first surface of the coated product 1 can reflect the light emitted by the second coaxial light source 3236 to the lens range of the three second CCD cameras 3224 of the second camera group 322q, and when the coated product 1 passes under the three second CCD cameras 3224, the three second CCD cameras 3224 can receive the light, so that the three second CCD cameras 3224 can take a picture of the appearance of the coated product 1 and complete the detection of appearance defect type B.

[0155] See also Figure 2 In this embodiment, after the carrying component 311 calibrates the initial position of the coated product 1, the transfer arm 315 can carry the coated product 1 calibrated to the initial position, starting from the first area 21, through the second area 22, and the camera group 322 will detect the appearance of the coating 10b of the coated product 1, and upload the result of the appearance detection to the data processing system. Finally, the transfer arm 315 will transport the coated product 1 to the third area 23. After the transfer arm 315 stops moving, the coating detection equipment 2 will use the barcode scanner 334 to photograph and identify the identity mark B of the coated product 1, obtain the product information of the coated product 1, and upload it to the data processing system in correspondence with the appearance detection result. It can be understood that the product information is the unique product code corresponding to each coated product 1 and other related product information.

[0156] Please also read Fig.12 . Fig.12 yes Figure 2 A schematic structural diagram of the second feeding mechanism 33 in the coating inspection device 2 is shown.

[0157] The second feeding mechanism 33 is located on the side of the appearance inspection mechanism 32 away from the bearing assembly 311, and is located in the third area 23. The second feeding mechanism 33 is used to deliver the coated product 1 that has completed the appearance inspection to the composite inspection mechanism 34. The second feeding mechanism 33 includes a support frame (not shown), a sliding member 331, a bearing plate 332, a transmission mechanism (not shown) and a barcode scanner 334. The support frame is installed on the top surface of the machine. The support frame includes two support plates. Along the Y-axis direction, the two support plates are respectively located on opposite sides of the first slide rail 313, and are spaced and arranged opposite to each other. The sliding member 331 is installed on the top surfaces of the two support plates. The bearing plate 332 is used to carry the coated product 1. There are two bearing plates 332, and the two bearing plates 332 are fixedly connected to the sliding member 331, and are arranged spaced apart from each other along the Y-axis direction. Each carrier plate 332 includes a carrier surface 332a facing away from the support frame, and a plurality of suction cups are provided on the carrier surface 332a, which can firmly adsorb the coated product 1 on the two carrier plates 332 through vacuum suction. The transmission mechanism is used to drive the sliding member 331 to slide along the X-axis direction, and then the two carrier plates 332 slide along the X-axis direction to transport the coated product 1 carried on the carrier plates 332 to the composite detection mechanism 34.

[0158] Please also read Figure 2 and Figure 4 In this embodiment, when the transfer arm 315 transports the coated product 1 to the third area 23, the transfer arm 315 is located at the bottom side of the two carrying plates 332 and does not contact the carrying plates 332. At this time, the barcode scanner 334 can scan the identity mark B of the coated product 1, identify and record the product information of the coated product 1. Thereafter, the transfer arm 315 can rise under the drive of the lifting mechanism 316, and transfer the coated product 1 after identity recognition to the top side of the two carrying plates 332. At this time, the transfer arm 315 is located between the two carrying plates 332.

[0159] Subsequently, the first suction cup 3151 of the transfer arm 315 stops working, and the first suction cup 3151 loses the vacuum suction force on the coated product 1. The suction cups on the two carrying plates 332 generate suction force, adsorbing the coated product 1 on the carrying surfaces 332a of the two carrying plates 332, so that the coated product 1 is separated from the transfer arm 315. Driven by the transmission mechanism, the coated product 1 adsorbed on the two carrying plates 332 is transferred to the fourth area 24, so that the composite detection mechanism 34 can detect the accuracy and film thickness of the coating 10b of the coated product 1.

[0160] In some other embodiments, the second loading mechanism 33 also includes a suction cup device 335. The suction cup device 335 can be set to absorb small-sized coated products 1, but the suction cup device 335 should be absorbed on the glass of the coated product 1, not on the coating 10b of the coated product 1, to avoid damaging the coating 10b of the coated product 1.

[0161] See also Figure 2 and Fig.13 . Fig.13 yes Figure 2 A schematic structural diagram of the composite detection mechanism 34 in the coating detection device 2 is shown.

[0163] The support platform 342 is used to support the coated product 1. The top surface of the support platform 342 is provided with a plurality of suction cups, which can adsorb the second surface of the coated product 1 transmitted through the third area 23, so that the composite detection mechanism 34 can detect the accuracy and film thickness of the coating 10b of the coated product 1. The rotation adjustment device 341 and the air-floating shock-absorbing platform are both located on the bottom side of the support platform 342, and are used to adjust the position of the support platform 342 on the XY plane. The air-floating shock-absorbing platform can reduce the impact of the vibration of the machine and the bottom surface on the detection. The multifunctional detection device 343, the Y-axis slide rail 348 and the Y-axis slider 349 are all located on the top side of the support platform 342. The multifunctional detection device 343 is used to detect the accuracy and film thickness of the coating 10b of the coated product 1.

[0164] The first X-axis rail 344 and the second X-axis rail 345 both extend in the X-axis direction. In the Y-axis direction, the first X-axis rail 344 and the second X-axis rail 345 are respectively located on opposite sides of the carrier 342 and are spaced apart from the carrier 342. The first X-axis slider 346 is slidably mounted on the first X-axis rail 344 and can slide on the first X-axis rail 344 in the X-axis direction, and the second X-axis slider 347 is slidably mounted on the second X-axis rail 345 and can slide on the second X-axis rail 345 in the X-axis direction.

[0165] The Y-axis slide rail 348 is installed on the first X-axis slider 346 and the second X-axis slider 347. Specifically, one end of the Y-axis slide rail 348 is installed on the first X-axis slider 346, and the other end is installed on the second X-axis slider 347. Among them, the Y-axis slide rail 348 extends along the Y-axis direction. The X-axis driving member can drive the Y-axis slide rail 348 to slide along the X-axis direction, thereby simultaneously driving the first X-axis slider 346 and the second X-axis slider 347 to slide on the first X-axis slide rail 344 and the second X-axis slide rail 345 respectively. In addition, the Y-axis slider 349 is slidably installed on the Y-axis slider 349, and can slide on the Y-axis slide rail 348 along the Y-axis direction. The Y-axis driving member can drive the Y-axis slider 349 to slide on the Y-axis slide rail 348.

[0166] The multifunctional detection device 343 is used to detect the position accuracy and film thickness of the coating 10a of the coating product 1. The multifunctional detection device 343 is installed on the Y-axis slider 349, and can slide along the Y-axis direction driven by the Y-axis slider 349. In this embodiment, the multifunctional detection device 343 includes an accuracy detection component 3431 and a film thickness measurement component 3432. The accuracy detection component 3431 and the film thickness measurement component 3432 are independent of each other, and are both installed on the side of the Y-axis slider 349 away from the Y-axis slide rail 348. Among them, along the Y-axis direction, the accuracy detection component 3431 and the film thickness measurement component 3432 are spaced from each other, and the accuracy detection component 3431 is located on the side of the film thickness measurement component 3432 facing the first X-axis slide rail 344.

[0167] The precision detection component 3431 is used to detect the position accuracy of the coating 10b of the coated product 1. That is, the precision detection component 3431 is used to detect the accuracy of the position area of ​​the coating 10b on the coated product 1. In this embodiment, the precision detection component 3431 includes an area array camera 3431a and an annular light source 3431b. The area array camera 3421a is used to take pictures of the coated product 1, and the annular light source 3431b provides a light source for the area array camera 3431a to detect the position accuracy of the coated product 1. It should be noted that the precision detection component 3431 is a device that can identify the position of the coated product 1 on the carrier 342, and can be photographed and identified using the area array camera 3431a. This application does not make any special restrictions on the precision detection component 3431.

[0168] The film thickness measurement component 3432 is used to measure the film thickness of the coating 10b of the coating product 1. In this embodiment, the position accuracy detection can be performed simultaneously with the film thickness detection. The film thickness measurement component 3432 includes a non-contact laser interferometer. The area array camera 3431a, the annular light source 3431b and the non-contact laser interferometer can move as a whole. The film thickness measurement component 3432 is a device for measuring the vertical distance between a plane and the film thickness measurement component 3432, which can be a non-contact laser interferometer or an infrared interferometer. The present application does not make any special limitation on the film thickness measurement component 3432.

[0169] Please also read Figure 1 , the film thickness measurement component 3432 can slide along the X-axis direction and the Y-axis direction under the drive of the Y-axis slider 349, and move to the first position along the path preset by the data processing system. At this time, the array camera 3431a takes a picture of the alignment mark A on the coating product 1, obtains the real-time position information of the alignment mark A, and uploads it to the data processing system. Since the preset position information of the alignment mark A is stored in the data processing system. Then the data processing system will compare the real-time position information of the alignment mark A with the preset position information, obtain the deviation value between the real-time position information of the alignment mark A and the preset position information, and convert the deviation value into a displacement signal through a preset calculation program, and send it to the rotation adjustment device 341. After receiving the displacement signal, the rotation adjustment device 341 adjusts the position of the carrier 342, thereby adjusting the coating product 1 adsorbed by the carrier 342, and moves the alignment mark A of the coating product 1 to the preset position information to complete the positioning of the coating product 1.

[0170] Subsequently, the multifunctional detection device 343 can slide again along the X-axis direction and the Y-axis direction driven by the Y-axis slider 349, and move to the second position located at the top side of the marking area 12 along the path preset by the data processing system. At this time, the area array camera 3431a takes a photo of the coated product 1 to obtain the first shooting position information X1; at the same time, the non-contact laser interferometer measures the distance to obtain the vertical distance from the coated product 1 to the non-contact laser interferometer, that is, the distance from the top surface of the marking area 12 of the coated product 1 to the non-contact laser interferometer is the first distance data L1. Then the first distance data L1 will be uploaded to the data processing system.

[0171] After obtaining the first distance data L1, the multifunctional detection device 343 is driven by the Y-axis slider 349 to slide again along the X-axis direction and the Y-axis direction, and passes through the third position, the fourth position, the fifth position ... the Nth position on the coating area 11 along the path preset by the data processing system, where N is any positive integer greater than or equal to 3. At the corresponding position, the area array camera 3431a is used to take a picture of the coating product 1 to obtain the second shooting position information X2, the third shooting position information X3, the fourth shooting position information X4 ... the Nth shooting position information Xn, and X2, X3, X4 ... Xn are compared with the corresponding preset information in the data processing system, the information of the coating area 11 deviating from the preset position is evaluated, and the final result of the position accuracy detection is obtained and entered into the data processing system.

[0172] While the multifunctional detection device 343 moves to the third position, the fourth position, the fifth position ... the Nth position, the non-contact laser interferometer works to measure the distance, and obtains the vertical distances from N positions on the coating 10b in the coating product 1 to the non-contact laser interferometer, and takes the average of these vertical distances to obtain the second distance data L2, L2 is the distance between the top surface of the coating 10b in the coating product 1 and the non-contact laser interferometer.

[0173] Specifically, when the multifunctional detection device 343 moves to the third position, the first vertical distance A1 from the area corresponding to the third position to the top surface of the coating 10b of the coated product 1 is obtained; when the multifunctional detection device 343 moves to the fourth position, the second vertical distance A2 from the area corresponding to the fourth position to the non-contact laser interferometer is obtained; when the multifunctional detection device 343 moves to the fifth position, the third vertical distance A3 from the top surface of the coating area 11 of the coated product 1 to the non-contact laser interferometer is obtained; when the multifunctional detection device 343 moves to the Nth position, the Nth distance data An from the top surface of the coating area 11 of the coated product 1 to the non-contact laser interferometer is obtained.

[0174] Thus, the second distance data The second distance data L2 does not include the thickness of the coating 10b, and the second distance data L2 is uploaded to the data processing system. Finally, the thickness L0 of the coating 10b of the coating product 1 is obtained, that is, L0=L2-L1, and then L0 is compared with the preset threshold of the data processing system. The final result of the film thickness detection is obtained and entered into the data processing system.

[0175] In this embodiment, the left and right ends of the Y-axis slide rail 348 are respectively installed on the first X-axis slider 346 and the second X-axis slider 347 and are fixedly connected. The precision detection component 3431 and the film thickness measurement component 3432 are both installed on the Y-axis slider 349, and can slide along the Y-axis slide rail 348 driven by the Y-axis slider 349, so that the precision detection component 3431 and the film thickness measurement component 3432 can achieve shooting and scanning of the coating product 1 in the same area, and send the shooting and scanning results to the data processing system, which are processed by the preset calculation program of the data processing system, thereby completing the detection of the position accuracy and film thickness of the coating 10b in the fourth area 24.

Specifically, part of the discharge slide rail 40 is located in the fifth area 25, part of the discharge slide rail 40 is located in the seventh area 27, and part of the discharge slide rail 40 is located in the eighth area 28.

[0178] The discharging mechanism 36 is slidably mounted on the discharging rail 40 and can slide on the discharging rail 40 along the X-axis direction. Specifically, the discharging mechanism 36 can reciprocate between the fifth area 25, the seventh area 27 and the eighth area 28 along the direction of the discharging rail 40. In this embodiment, the discharging mechanism 36 includes a discharging table 361, a discharging drive 362, a discharging suction cup 363 and a discharging lifting mechanism 364. The discharging table 361 is slidably mounted on the discharging rail 40 and can slide on the discharging rail 40 along the X-axis direction. The discharging drive 362 can drive the discharging table 361 to slide on the discharging rail 40 along the X-axis direction to the cache mechanism 38 or the unloading mechanism 39. Among them, the discharging drive 362 and the discharging lifting mechanism 364 are electrically connected to the processor, and both can work according to the instructions of the processor.

[0179] The discharge lifting mechanism 364 is installed on the top surface of the discharge platform 361, and the discharge suction cup 363 is installed on the top side of the discharge lifting mechanism 364. Specifically, the discharge lifting mechanism 364 can drive the discharge suction cup 363 to move along the Z-axis direction. The discharge suction cup 363 includes a plurality of small suction cups, and the plurality of small suction cups can adsorb the coating product 1 transported from the composite detection mechanism 34 by the transport mechanism 35 on the top side of the discharge suction cup 363 through vacuum suction. At this time, the coating product 1 can follow the discharge suction cup 363 to move along the Z-axis direction under the drive of the discharge lifting mechanism 364, and can also follow the discharge platform 361 to slide along the X-axis direction on the discharge slide rail 40 under the drive of the discharge driving member 362.

[0180] The material removal mechanism 39 includes two material removal mounting seats 391, two material removal brackets 392, two material removal bearing members 393 and four material removal stoppers 394. The two material removal mounting seats 391 are both mounted on the top surface of the machine platform, and the two material removal brackets 392 are respectively mounted on the top surfaces of the two material removal mounting seats 391 and can slide relative to the material removal mounting seats 391 along the Y-axis direction. Along the Y-axis direction, the two material removal mounting seats 391 are spaced apart and arranged opposite to each other, and the two material removal brackets 392 are spaced apart and arranged opposite to each other.

[0181] Each material unloading support 393 is installed on a material unloading bracket 392. Specifically, each material unloading support 393 is installed on the top surface of a material unloading bracket 392. The material unloading support 393 has a bearing surface, and the bearing surface can bear the coating product 1. The bearing surfaces of the two material unloading support 393 bear the coating product 1 together. At this time, the second surface of the substrate 10a in the coating product 1 contacts the bearing surfaces of the two material unloading support 393.

[0182] Two material-cutting stoppers 394 are installed on a material-cutting bracket 392. Specifically, along the X-axis direction, every two material-cutting stoppers 394 are installed on the top surface of a material-cutting bracket 392. Every two material-cutting stoppers 394 are located on opposite sides of a material-cutting support 393, and are spaced apart from the material-cutting support 393. When the bearing surfaces of the two material-cutting support 393 jointly carry the coating product 1, each material-cutting bracket 392 drives the two material-cutting stoppers 394 to slide relative to a material-cutting mounting seat 391, and the two material-cutting brackets 392 are relatively close. At the same time, the four material-cutting stoppers 394 can be adjusted in position according to the different sizes of the coating product 1, and jointly form a bearing surface, so that the bottom surface of the coating product 1 contacts the bearing surface, and the coating product 1 is adjusted to a preset material-cutting position suitable for the next process. Then, the coating product 1 will enter the next process. It can be understood that the coating products 1 of the same batch have the same size parameters, so the coating products 1 of the same batch have the same preset material-cutting position.

[0183] Specifically, when the discharging mechanism 36 carries the coated product 1 and slides to the bottom of the unloading mechanism 39, the plane where the coated product 1 is located is higher than the top surface of the unloading mechanism 39. The discharging suction cup 363 stops working, and the suction force of the suction cup disappears. The discharging lifting mechanism 364 of the discharging mechanism 36 slides along the negative direction of the Z axis, so that the bottom surface of the coated product 1 contacts the top surface of the unloading mechanism 39. Then the discharging mechanism 36 slides along the negative direction of the X axis of the discharging slide rail to the fifth area 25.

[0184] The re-judgment mechanism 37 is located in the sixth area 26, and is used to perform a secondary inspection on the coating 10b of the coating product 1. Specifically, the re-judgment mechanism 37 is used to receive the coating product 1 that is judged to have appearance defects according to the appearance inspection results in the data processing system. The re-judgment mechanism 37 includes a re-judgment platform 371, and the re-judgment platform 371 is located on the top of the re-judgment mechanism 37. The top surface of the re-judgment platform 371 is a bearing surface, which can carry the coating product 1 transported by the transport mechanism 35. In addition, the re-judgment mechanism 37 is also provided with a manual workstation area (not marked in the figure). People can be located in the manual workstation area, and perform appearance inspection on the coating product 1 located on the bearing surface of the re-judgment platform 371 again, and give the result of the appearance inspection re-inspection. If the inspection result of the appearance inspection mechanism 32 is wrong, the appearance inspection result already in the system is replaced. If the inspection result of the appearance inspection mechanism 32 is correct, it is confirmed that the appearance inspection result already in the system can be used to reduce the misjudgment rate of the appearance inspection result of the coating inspection device 2.

[0185] The transport mechanism 35 is used to transport the coated product 1 located on the carrier 342 to the discharge platform 362 or the re-inspection mechanism 37, and is also used to transport the coated product 1 located on the discharge platform 362 to the re-inspection mechanism 37, and is used to transport the coated product 1 located on the re-inspection mechanism 37 to the discharge platform 362. In this embodiment, the transport mechanism 35 includes a transport bracket 351, an arm bracket 352, an arm suction cup 353, a transport slider 354, a transport rail 355 and a transport drive member (not shown).

In this embodiment, the transport bracket 351 includes three transport supports 3511 and a transport mounting member 3512. The three transport supports 3511 are arranged at intervals and along the Y-axis direction. The transport mounting member 3512 is located on the top side of the three transport supports 3511. The left side of the transport mounting member 3512 is installed with a barcode scanner 334, and the right side of the transport mounting member 3512 is installed with an arm suction cup 353, a transport slider 354 and a transport slide rail 355.

[0187] The transport rail 355 is installed on the transport bracket 351. Specifically, the transport rail 355 is installed on the side of the transport mounting member 3512 away from the unloading mechanism. The transport rail 355 is a strip-shaped body and extends along the Y-axis direction. Part of the transport rail 355 is located in the fourth area 24, part of the transport rail 355 is located in the fifth area 25, and part of the transport rail 355 is located in the sixth area 26. At this time, the transport rail 355 is located on the top side of the composite detection mechanism 34, the unloading mechanism 36 and the re-judgment mechanism 37.

[0188] The transport slider 354 is slidably mounted on the transport rail 355 and can slide on the transport rail 355 along the Y-axis direction. The transport driver can drive the transport slider 354 to slide on the transport rail 355. That is, along the Y-axis direction, the transport slider 354 can slide back and forth between the fourth area 24, the fifth area 25 and the sixth area 26 under the drive of the transport driver. The arm support 352 is mounted on the side of the transport slider 354 away from the transport rail 355 and can slide along the X-axis direction under the drive of the transport slider 354.

[0189] The arm suction cup 353 is installed on the arm bracket 352, and can slide relative to the arm bracket 352 along the Z-axis direction. Among them, the transport mechanism 35 also includes a transport lifting mechanism 357, and the transport lifting mechanism 357 is used to drive the arm suction cup 353 to slide relative to the arm bracket 352 along the Z-axis direction. Specifically, the arm suction cup 353 is installed at the bottom of the arm bracket 352. The arm suction cup 353 includes one or more suction cups that can generate vacuum suction, so that the arm suction cup 353 can grab the coated product 1, thereby driving the coated product 1 to slide relative to the arm bracket 352 along the Z-axis direction.

[0190] In this embodiment, the transport slider 354 can slide between the fourth area 24, the fifth area 25 and the sixth area 26 along the direction of the transport rail 355. The arm suction cup 353 of the arm bracket 352 can generate a vacuum suction force to suck the coated product 1. Thus, the transport slider 354 drives the coated product 1 to slide between the fourth area 24, the fifth area 25 and the sixth area 26 along the Y-axis direction.

[0191] First, the arm bracket 352 and the arm suction cup 353 of the conveying mechanism 35 move to the top of the coated product 1. The arm suction cup 353 descends to a preset position, and the arm suction cup 353 starts to work. So that the bottom surface of the arm suction cup 353 contacts the first surface of the coated product 1, and the coated product 1 is adsorbed on the arm suction cup 353. The arm suction cup 353 rises to a preset position so that the coated product 1 does not contact the composite detection mechanism 34, the discharging mechanism 36 and the re-inspection mechanism 37. When the coated product 1 moves to the target position along the conveying slide rail 355 with the arm bracket 352, the arm bracket 352 and the arm suction cup 353 descend until the coated product 1 contacts the discharging suction cup 363 or the re-inspection table 371, and the arm suction cup 353 stops working and loses the suction force on the first surface of the coated product 1. Then the arm support 352 and the arm suction cup 353 rise until the bottom surface of the arm suction cup 353 leaves the first surface of the coated product 1, and the coated product 1 is located on the top surface of the discharge suction cup 363 or the supporting surface of the review table 371, ready for the next process operation.

[0192] Please also read Fig.15 . Fig.15 yes Fig.14 A schematic structural diagram of the cache mechanism 38 is shown.

[0193] The cache mechanism 38 is located in the sixth area 26 and crosses the discharge slide rail 40 along the Y-axis direction. Specifically, the cache mechanism 38 is located between the unloading mechanism and the conveying mechanism 35, and is spaced apart from the unloading mechanism and the conveying mechanism 35. In this embodiment, the cache mechanism 38 includes a mounting bracket 381, a mounting plate 382, ​​a cache driving member 383, a lifting guide rod 384, a first positioning plate 385, a second positioning plate 386, a positioning guide rod 387 and a cache member 388.

[0194] The mounting bracket 381 is installed on the top surface of the machine. The mounting bracket 381 is used to support other components of the cache mechanism 38, and its shape can be designed according to actual production needs. The mounting plate 382 is installed on the top surface of the mounting bracket 381, the first positioning plate 385 is located on the top side of the mounting plate 382, ​​and the second positioning plate 386 is located on the bottom side of the mounting plate 382. The lifting guide rod 384 passes through the mounting plate 382 and can move relative to the mounting plate 382 along the Z-axis direction. Among them, one end of the lifting guide rod 384 is fixedly connected to the bottom surface of the first positioning plate 385, and the other end is fixedly connected to the top surface of the second positioning plate 386. Thereby, the first positioning plate 385 and the second positioning plate 386 can move relative to the mounting plate 382 along the Z-axis direction under the drive of the lifting guide rod 384.

[0195] The positioning guide rod 387 and the buffer member 388 are both located at the bottom side of the second positioning plate 386. One end of the positioning guide rod 387 is fixedly connected to the bottom surface of the second positioning plate 386, and the other end is fixedly connected to the top surface of the buffer member 388. Thus, the positioning guide rod 387 and the buffer member 388 can move along the Z-axis direction under the drive of the second positioning plate 386.

[0196] The cache member 388 is a device capable of storing the coated product 1, and is located at the bottom of the cache mechanism 38. The cache member 388 is fixedly connected to the positioning guide rod 387, and can slide along the Z-axis direction driven by the positioning guide rod 387. The cache member 388 is a multi-layer structure, and is used to store multiple coated products 1.

[0197] The cache component 388 includes a cache component mounting plate 3881, a cache component bracket 3882 and a cache component carrier 3883. The cache component mounting plate 3881 is fixedly connected to the positioning guide rod 387, and can slide along the Z-axis direction under the drive of the positioning guide rod 387. The cache component bracket 3882 is fixedly connected to the bottom side of the cache component mounting plate 3881. The cache component carrier 3883 is fixedly connected to the cache component bracket 3882. The cache component carrier 3883 is a multi-layer structure, and each layer of the cache component 388 can store a coating product 1 to prevent the first surface of the coating product 1 from being bumped. At the same time, the cache component 388 can cooperate with the discharging mechanism 36, so that the discharging mechanism 36 can smoothly access any layer of the coating product 1 stored on the cache component carrier 3883.

[0198] In this embodiment, the cache drive member 383 is a screw structure, that is, the motor 3831 of the cache drive member 383 can drive the screw 3832 to rotate. The screw nut 3833 is fixedly connected to the second positioning plate 386, so that the screw 3832 pushes the first positioning plate 385 and the second positioning plate 386 to reciprocate along the lifting guide rod 384 in the Z-axis direction. And the second positioning plate 386 can drive the cache member 388 to reciprocate along the positioning guide rod 387 in the Z-axis direction. So as to realize that the cache drive member 383 drives the cache member 388 to reciprocate in the Z-axis direction. And the cache member 388 can cooperate with the discharging mechanism 36 to realize the storage and access of the coating product 1 that fails the appearance inspection.

[0199] In this embodiment, when the coated product 1 completes the position accuracy detection and film thickness detection in the fourth area 24, the suction cup of the composite detection mechanism 34 will stop working, and the suction cup loses the suction force on the coated product 1. As a result, the conveying mechanism 35 can absorb the coated product 1 on the bottom of the conveying mechanism 35 through the suction force of the arm suction cup 353, and move with the conveying mechanism 35 to the area set by the data processing system.

[0200] After the conveying mechanism 35 firmly adsorbs the coated product 1, the data processing system will send a corresponding electrical signal H to the conveying mechanism 35 according to the appearance inspection result of the coated product 1 and the idle status of the re-judgment mechanism 37, and place the coated product 1 in the corresponding area.

[0201] Specifically, the electrical signal H includes five types, and the five electrical signals H are respectively a first electrical signal H1, a second electrical signal H2, a third electrical signal H3, a fourth electrical signal H4 and a fifth electrical signal H5.

[0202] When the appearance inspection result of the coated product 1 adsorbed by the conveying mechanism 35 is qualified, and there may or may not be a product under inspection on the re-judgment mechanism 37, the data processing system will send a first electrical signal H1 to the conveying mechanism 35, and place the coated product 1 on the top surface of the discharging mechanism 36, and then the discharging mechanism 36 will transport the coated product 1 to the unloading mechanism 39.

[0203] When the appearance inspection result of the coated product 1 adsorbed by the conveying mechanism 35 is unqualified and there is no product under inspection on the re-inspection mechanism 37, the data processing system will send a second electrical signal H2 to the conveying mechanism 35, and place the coated product 1 in the sixth area 26 for manual re-inspection. Then, a third electrical signal H3 is sent to the conveying mechanism 35, so that the conveying mechanism 35 places the coated product 1 on the sixth area 26 on the top surface of the discharging mechanism 36, and the discharging mechanism 36 then transports the coated product 1 to the unloading mechanism 39.

[0204] When the appearance inspection result of the coated product 1 adsorbed by the conveying mechanism 35 is unqualified, and there is a product under inspection on the re-judgment mechanism 37, the data processing system will send a fourth electrical signal H4 to the conveying mechanism 35, and place the coated product 1 on the top surface of the discharging mechanism 36. Then the discharging mechanism 36 will transport the coated product 1 to the cache mechanism 38. Specifically, with the cooperation of the driving member, the cache member 388 will drop to a position horizontal to the top surface of the discharging mechanism 36, so that the discharging mechanism 36 can carry the coated product 1 and move along the negative direction of the X-axis to the bottom preset position of the cache member 388, so that the coated product 1 can be stored in the cache member 388. When there is no product under inspection in the re-judgment mechanism 37, the discharging mechanism 36 will transport the coated product 1 in the cache member 388 to the fifth area 25. The data processing system sends a fifth electrical signal H5 to the conveying mechanism 35, so that the conveying mechanism 35 places the coated product 1 located on the top surface of the discharging mechanism 36 on the top surface of the re-judgment mechanism 37 for manual re-judgment inspection. Then, a third electrical signal H3 is sent to the transport mechanism 35 , so that the transport mechanism 35 places the coated product 1 located on the sixth area 26 on the top surface of the discharge mechanism 36 , and then the discharge mechanism 36 transports the coated product 1 to the unloading mechanism 39 .

[0205] In the coating inspection device 2 provided by the present application, the appearance inspection mechanism 32 can realize the appearance inspection of the coating 10b of the coating product 1, and the composite inspection mechanism 34 can realize the detection of the position accuracy and film thickness of the coating 10b of the coating product 1, that is, the coating inspection device 2 can automatically realize the appearance inspection, position accuracy inspection and film thickness inspection of the coating 10b of the coating product 1. Compared with manual inspection, it realizes the automatic handling of products, and greatly improves the inspection rate and accuracy, thereby saving costs and improving production capacity.

[0206] See also Fig.16 . Fig.16 : is a flow chart of a coating detection method provided in an embodiment of the present application, which is implemented by the above-mentioned coating detection device 2. The coating detection method includes:

[0207] Step S1, placing the coated product 1 on the carrying assembly 311. The coating 10b is located on the side of the substrate 10a away from the carrying assembly 311. Specifically, the carrying assembly 311 of the first loading mechanism 31 carries the coated product 1 that has completed the previous process flow, and calibrates the coated product 1 to the initial state preset by the data processing system.

[0208] In step S2, the transfer arm 315 carries the coated product 1 carried by the carrying assembly 311 to the second loading mechanism 33, and at the same time, the appearance inspection mechanism 32 inspects the appearance of the coating 10b. Specifically, the transfer arm of the first loading mechanism 31 carries the coated product 1 located in the first area 21 and slides to the third area 22, and passes through the appearance inspection mechanism 32 located in the second area 22, and at the same time, the appearance of the coated product 1 is inspected.

[0209] Specifically, after the bearing assembly 311 calibrates the initial position of the coated product 1, the lifting mechanism 316 and the transfer arm 315 move to the bottom of the coated product 1. The first suction cup 3151 of the transfer arm 315 uses vacuum suction to firmly adsorb the coated product 1 on the top side of the transfer arm 315. The lifting mechanism 316 moves along the positive direction of the Z axis to separate the coated product 1 from the plane where the bearing assembly 311 is located. After completing the above actions, the first slider 314, under the power provided by the first driving member, drives the coated product 1, the lifting mechanism 316 and the transfer arm 315 to pass through the first area 21, the second area 22 and the third area 23 in turn, and finally stays in the third area 23, waiting for the second loading mechanism 33 to perform the next step of the operation on the coated product 1.

[0210] When passing through the second area 22, the camera group 322 of the appearance inspection mechanism 32 takes photos of the appearance of the coating 10b of the coated product 1 for inspection, the first camera group 322p detects the first appearance defect of the coating 10b, and the second camera group 322q detects the second appearance defect of the coating 10b, and the results of the appearance inspection are uploaded to the data processing system, and the appearance inspection of the coated product 1 is completed at the same time. At this time, the first coaxial light source 3233 provides a coaxial light source for the first camera group 322p, and the second coaxial light source 3236 provides a coaxial light source for the second camera group 322q. Among them, the defect type of the second appearance defect is different from that of the first appearance defect.

[0211] Step S3, the barcode scanner 334 obtains the product information of the coated product 1 carried on the carrying plate 332. Specifically, after the transfer arm 315 stops moving, the coating inspection device 2 will use the barcode scanner 334 to take a photo of the identity mark B of the coated product 1 to obtain the original information of the coated product 1, and upload it to the data processing system in correspondence with the appearance inspection result. It can be understood that the original information is the unique product code and product information corresponding to each coated product 1.

[0212] In step S4, the transmission mechanism transports the coated product 1 carried on the carrier plate 332 to the carrier platform 342, wherein the coating 10b is located on the side of the substrate 10a away from the carrier platform 342. Specifically, after obtaining the product code, product information and corresponding appearance inspection results of the coated product 1, the first suction cup 3151 of the transfer arm stops working, and the first suction cup 3151 loses the vacuum suction force on the coated product 1. The suction cup device 335 of the second feeding mechanism 33 generates suction force to separate the coated product 1 from the transfer arm 315. Driven by the transmission mechanism, the coated product 1 placed on the top side of the carrier plate 332 is transferred to the composite inspection mechanism 34 located in the fourth area 24.

[0213] Step S5, the rotation adjustment device 341 adjusts the position of the carrier 342. Specifically, the film thickness measurement component 3432 can slide along the X-axis direction and the Y-axis direction under the drive of the Y-axis slider 349, and move to the first position along the path preset by the data processing system. At this time, the array camera 3431a takes a picture of the alignment mark A on the coating product 1, obtains the real-time position information of the alignment mark A, and uploads it to the data processing system. Since the preset position information of the alignment mark A is stored in the data processing system. Then the data processing system will compare the real-time position information of the alignment mark A with the preset position information, obtain the deviation value between the real-time position information of the alignment mark A and the preset position information, and convert the deviation value into a displacement signal through a preset calculation program, and send it to the rotation adjustment device 341. After receiving the displacement signal, the rotation adjustment device 341 adjusts the position of the carrier 342, thereby adjusting the coating product 1 adsorbed by the carrier 342, and moving the alignment mark A of the coating product 1 to the preset position information to complete the positioning of the coating product 1.

[0214] Step S6, the multifunctional detection device 343 detects the position accuracy and film thickness of the coating 10b. Specifically, the accuracy detection component 3431 detects the position accuracy of the coating 10b, and uploads the position accuracy detection result to the data processing system, and the film thickness measurement component 3432 detects the film thickness of the coating 10b, and uploads the film thickness detection result to the data processing system. Among them, the annular light source 3431b of the accuracy detection component 3431 provides light source for the area array camera 3431a, the area array camera 3431a takes a picture of the coating product 1, and the non-contact laser interferometer detects the thickness of the coating 10b of the coating product 1.

[0215] Specifically, the left and right ends of the Y-axis slide rail 348 are fixedly connected to the first X-axis slider 346 and the second X-axis slider 347 respectively, and the precision detection component 3431 and the film thickness measurement component 3432 can be assembled with the Y-axis slider 349 and slide along the Y-axis slide rail 348, so that the area array camera 3431a and the non-contact laser interferometer of the precision detection component 3431 and the film thickness measurement component 3432 can scan the preset area of ​​the data processing system on the coating product 1, and after calculation by the data processing system, finally complete the position accuracy detection and film thickness detection of the coating product 1 in the fourth area 24 at the same time.

[0216] S7, judging whether the appearance inspection result of the coating 10b of the coated product 1 detected by the appearance inspection mechanism 32 is qualified, if so, executing step S8, if not, executing step S10. Specifically, the processor compares the actual photo fed back by the appearance inspection mechanism 32 with the preset photo, and finally analyzes whether the appearance inspection result of the coating 10b of the coated product 1 is qualified.

[0217] In step S8, the conveying mechanism 35 conveys the coated product 1 carried on the carrying platform 342 to the unloading platform 361. Specifically, the suction cup of the composite detection mechanism 34 stops working, and the suction cup loses the adsorption force on the coated product 1. Thus, the conveying mechanism 35 can adsorb the coated product 1 to the bottom of the conveying mechanism 35 through the suction force of the arm suction cup 353. At the same time, the processor sends a first electrical signal H1 to the conveying mechanism 35 according to the appearance inspection result of the coated product 1 and the idle state of the re-judgment mechanism 37, and the conveying mechanism 35 conveys the coated product 1 to the unloading platform 361.

[0218] Step S9, transfer the coated product 1 carried on the discharge platform 361 to the unloading mechanism 39. Specifically, the discharge mechanism 36 transfers the coated product 1 carried on the discharge platform 361 to the unloading support 393 of the unloading mechanism 39 to complete the detection of the coated product 1. Among them, the discharge platform 361 carries the coated product 1, starts from the fifth area 25, and slides along the direction of the discharge slide rail 40 to the bottom of the unloading mechanism 39. At this time, the plane where the coated product 1 is located is higher than the top surface of the unloading mechanism 39. The discharge suction cup 363 stops working, and the suction force of the discharge suction cup 363 disappears. The discharge lifting mechanism 364 of the discharge mechanism 36 slides along the negative direction of the Z axis, so that the bottom surface of the coated product 1 contacts the top surface of the unloading mechanism 39. Then the discharge mechanism 36 slides along the negative direction of the X axis of the discharge slide rail to the fifth area 25 to transfer the coated product 1 to the unloading mechanism 39.

[0219] Step S10, determine whether there is a product under inspection on the re-inspection mechanism 37, if not, execute step S11, if yes, execute step S14. Specifically, the processor determines whether there is a product under inspection on the re-inspection mechanism 37, and sends an electrical signal to the transport mechanism 35 according to the determination result.

[0220] In step S11, the conveying mechanism 35 conveys the coated product 1 carried on the carrying platform 342 to the re-inspection mechanism 37. Specifically, when the appearance inspection result of the coated product 1 adsorbed by the conveying mechanism 35 is unqualified and there is no product under inspection on the re-inspection mechanism 37, the processor sends a second electrical signal H2 to the conveying mechanism 35 and conveys the coated product 1 to the re-inspection mechanism 37.

[0221] Step S12, a secondary inspection is performed on the coating 10b of the coated product 1 placed in the re-inspection mechanism 37. Specifically, the coating 10b of the coated product 1 placed in the re-inspection mechanism 37 is manually re-inspected, and the result of the appearance inspection re-inspection is manually given. If the inspection result of the appearance inspection mechanism 32 is wrong, the existing appearance inspection result in the system is replaced. If the inspection result of the appearance inspection mechanism 32 is correct, the existing appearance inspection result in the system is confirmed to reduce the misjudgment rate of the appearance inspection result of the coating inspection device 2.

[0222] In step S13, the transport mechanism 35 transports the coated product 1 located at the re-judgment mechanism 37 to the discharge platform 361. Specifically, the processor sends a third electrical signal H3 to the transport mechanism 35, so that the transport mechanism 35 places the coated product 1 on the sixth area 26 on the top surface of the discharge mechanism 36. Then, step S9 is executed.

[0223] In step S14, the conveying mechanism 35 conveys the coated product 1 carried on the carrying platform 342 to the unloading platform 361. Specifically, when the appearance inspection result of the coated product 1 adsorbed by the conveying mechanism 35 is unqualified and there is a product under inspection on the re-judgment mechanism 37, the processor sends a fourth electrical signal H4 to the conveying mechanism 35 and places the coated product 1 on the unloading platform 361 of the unloading mechanism 36.

[0224] Step S15, the coated product 1 carried on the discharge table 361 is transferred to the cache mechanism 38. Specifically, the discharge mechanism 36 will transport the coated product 1 to the cache mechanism 38. Specifically, under the cooperation of the driving member, the cache member 388 will drop to a position horizontal to the fifth area 25, so that the discharge mechanism 36 can carry the coated product 1 and move along the negative direction of the X-axis to the bottom side preset position of the cache member 388, so that the coated product 1 can be placed in the cache member 388 for storage.

[0225] Step S16, transporting the coated product 1 placed in the buffer mechanism 38 to the discharging platform 361. Specifically, when the re-judgment mechanism 37 has no products under inspection, the discharging mechanism 36 transports the coated product 1 in the buffer 388 to the discharging platform 361.

[0226] In step S17, the transport mechanism 35 transports the coated product 1 carried on the discharge table 361 to the re-judgment mechanism 38. Specifically, the processor sends a fifth electrical signal H5 to the transport mechanism 35, so that the transport mechanism 35 places the coated product 1 located in the fifth area 25 to the re-judgment mechanism 37. Subsequently, step S12, step S13 and step S9 are sequentially executed.

[0227] The present application provides a coating inspection device 2. The coating product 1 is loaded from the first feeding mechanism 31, and driven by the second feeding mechanism 33, it moves according to the path preset by the data processing system. After the camera group 322 of the appearance inspection mechanism 32 takes pictures and calculates, the appearance inspection result of the coating product 1 is obtained, and the result is uploaded to the data processing system. Then the second feeding mechanism 33 carries the coating product 1 that has completed the appearance inspection to the composite inspection mechanism 34, and the multifunctional inspection device 343 measures and calculates the coating product 1 to obtain the coating 10b position accuracy inspection result and the coating 10b thickness inspection result, and uploads the result to the data processing system. After that, the conveying mechanism 35 firmly adsorbs the coating product 1, and at the same time, the data processing system will send a corresponding electrical signal H to the conveying mechanism 35 according to the appearance inspection result of the coating product 1 and the idle situation of the re-judgment mechanism 37, and place the coating product 1 in the corresponding area. Finally, the coating product 1 will be transported to the top side of the discharging mechanism 36, and the discharging mechanism 36 will transport the coating product 1 to the unloading mechanism 39. The fully automatic detection of the coating 10b appearance detection, the coating 10b position accuracy detection and the coating 10b film thickness detection of the coating product 1 greatly improves the detection speed and accuracy compared with manual detection, thereby saving costs and improving production capacity. The online detection method of the present application is simple and saves manpower and material costs.

[0228] In the coating inspection device 2 provided by the present invention, the processor controls the first feeding mechanism 31, the appearance inspection mechanism 32, the second feeding mechanism 33, the composite inspection mechanism 34, the discharging mechanism 36, the re-judgment mechanism 37, the transport mechanism 35, the buffer mechanism 38, and the unloading mechanism 39 through electrical connection; and enables the coating inspection device 2 to complete the appearance inspection, position accuracy inspection and film thickness inspection of the coating 10b of the coating product 1 according to the preset program of the data processing system. Compared with manual inspection, the product is automatically transported, and the inspection rate and accuracy are greatly improved, thereby saving costs and increasing production capacity.
