[0031] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] like Figures 1 to 15 An appearance detection module shown includes a frame 1, which includes a feeding mechanism 2, a material conveying mechanism 3, a rotating mechanism 4, an appearance detection mechanism 5, and a flipping mechanism 6. The feeding mechanism 2 is provided with a feeding tray 21 for placing materials, and a feeding drive assembly 22 for driving the feeding tray 21 to move. The material conveying mechanism 3 is provided with a conveying drive assembly 31 for moving between the feeding mechanism 2 and the rotating mechanism 4, and a material picking assembly 32 connected to the conveying drive assembly 31 and used to drive material transfer. The rotating mechanism 4 is provided with a rotating mechanism accommodating tray 41 for the material to extend into, and a rotating drive assembly 42 for driving the rotating mechanism accommodating tray 41 to rotate to the detection area of ​​the appearance detection mechanism 5. The appearance detection mechanism 5 is used to detect the material on the rotating mechanism accommodating tray 41, and the flipping mechanism 6 is used to flip the material located on the rotating mechanism accommodating tray 41 and at least one side of which has been detected. The design of the present invention enables materials to be fully inspected in an automated environment, effectively solving the problems existing in the existing detection method combining manual and auxiliary equipment, improving detection accuracy and efficiency, reducing manual operation errors, reducing labor intensity and labor costs, and improving the continuity and stability of the production line.

[0033] Specifically, staff or equipment such as manipulators can transfer the materials to be inspected to the feed tray in advance. The feed drive assembly can drive the feed tray to move, ensuring that the materials are smoothly and continuously transported to the next processing link, reducing material damage or position deviation caused by improper human operation. The conveying drive assembly moves between the feed mechanism and the rotating mechanism to facilitate the transfer of materials. The material collection assembly is connected to the conveying drive assembly and is responsible for accurately taking the materials from the upper side of the feed tray and transferring them to the rotating mechanism accommodating tray. This material transfer method reduces the need for manual handling and improves the efficiency and accuracy of material transportation. The rotating mechanism accommodating tray is used to temporarily store the materials to be inspected. The rotating drive assembly can drive the rotating mechanism accommodating tray to rotate and deliver the materials to the working areas of the appearance inspection mechanism and the flipping mechanism in turn. The rotating mechanism can accurately control the position of the materials to ensure that the angle of the material rotation is consistent each time, and each side of the material can be accurately inspected by the appearance inspection mechanism. The appearance inspection mechanism can perform a full range of appearance inspection on the material rotated to the inspection area and record the inspection results in real time. The appearance inspection mechanism includes high-precision cameras, sensors and other equipment, which can quickly and accurately detect the appearance quality of the material and reduce human visual fatigue and errors. The flipping mechanism flips the material that has been inspected on at least one side so that the appearance inspection mechanism can inspect the remaining sides to ensure the comprehensiveness of the inspection.

[0034] Furthermore, by integrating the feeding, conveying, rotation, detection and flipping into an automated module, the automated detection process of the present invention reduces human intervention and improves the accuracy and efficiency of detection. The appearance detection module can be monitored and managed by the control system to achieve real-time data collection and analysis, as well as automatic diagnosis and processing of faults. All-round detection ensures that each surface of the material can be effectively detected. Intelligent control improves the reliability and ease of use of the system and reduces missed detection and false detection.

[0035] Specifically, workers only need to monitor the operating status of the equipment and do not need to concentrate for a long time on manual inspection, which reduces labor intensity and improves work safety by reducing inspection errors caused by visual fatigue. Close cooperation between various mechanisms realizes continuous and stable transmission and inspection of materials, reducing production interruptions and waiting time caused by improper manual operation.

[0036] like Figure 4In the illustrated appearance inspection module, the feed drive assembly 22 includes a conveying bracket 221, a feed conveying line 222 located inside the conveying bracket 221, and the feed tray 21 is provided with a tray stopper 211 that is in contact with the conveying bracket 221, and a plurality of tray accommodating cavities 212 for placing the materials. Furthermore, the conveying bracket is firmly installed in the working area as a supporting structure to provide support and positioning reference for subsequent material conveying. The conveying bracket is made of metal such as stainless steel or other strong materials, and can withstand wear and impact during continuous operation.

[0037] Optionally, the feed conveyor line is located on the inner side of the conveying bracket and can be a continuous belt conveyor, roller conveyor, chain conveyor, roller system or other form of linear moving device. The feed conveyor line is driven by a motor, and the power is transmitted to the conveyor line through a transmission system (such as pulleys, chains, gears, etc.). It can transport materials from one end to the other along a preset path, thereby realizing continuous and uniform transportation of materials. Preferably, the feed conveyor line is a conveyor belt.

[0038] Specifically, the feed tray is used in conjunction with the feed conveyor line to transport materials to designated locations in an orderly manner. The tray limiter is used to limit and abut with the conveying bracket, which can ensure that the tray maintains a stable posture and position during the conveying process and prevent the materials from tipping over or shifting during the conveying process. The feed tray is provided with a plurality of tray accommodating cavities, which are used to place and fix materials. The shape, size and layout of the tray accommodating cavity are coordinated with the shape and size of the material to ensure the stability and safety of the material during the conveying process. In addition, shock-absorbing materials, fixing belts or separators can be arranged inside the tray accommodating cavity to prevent the materials from colliding with each other or being damaged during the conveying process.

[0039] Specifically, the material to be inspected is first placed in the tray accommodating cavity of the feed tray, and the feed tray containing the material is transported to the inspection area along the conveying bracket through the feed conveyor line. The tray limit part abuts against the conveying bracket limit to ensure the stable position of the feed tray during the conveying process to avoid the displacement of the material position due to shaking. After the material arrives at the inspection area, the appearance inspection step is performed.

[0040] like Figure 4 and Fig.13In the appearance inspection module shown, the feed drive assembly 22 also includes a feed lifting assembly 223 located at the lower side of the feed tray 21, and a conveying bracket limiting portion 224 connected to the conveying bracket 221 and abutting against the tray limiting portion 211, and the feed lifting assembly 223 is used to lift the feed tray 21 to move toward the material picking assembly 32. Furthermore, the feed lifting assembly enables the feed tray to rise from a low position to a high position, and the feed tray can automatically move toward the material picking assembly without human intervention or manual operation, thereby greatly improving the automation level of the production line. This not only reduces labor costs, but also reduces errors and delays that may be caused by human factors. The close abutment between the tray limiting portion and the conveying bracket limiting portion provides a strong guarantee for the stability of the feed tray during the conveying process, reduces the possibility of displacement or tilting of the feed tray due to external forces, and thus enhances the stability and reliability of the entire feed drive assembly.

[0041] Specifically, the tray limiting portion is arranged in parallel with the conveying bracket limiting portion. When the tray limiting portion abuts against the conveying bracket limiting portion, the upper end surface of each material to be detected is on a horizontal plane at the same height, avoiding the entire tray from tilting, thereby ensuring that the material picking component can grab or adsorb the material at the same position each time.

[0042] Specifically, when the feeding tray reaches the designated position, the feeding lifting assembly starts to lift the feeding tray and move it toward the material taking assembly. After the feeding tray is lifted into place, the tray limiter abuts against the conveying bracket limiter, and the material taking assembly takes the material out of the tray accommodating cavity for subsequent inspection or processing.

[0043] Furthermore, in order to improve the stable structure of the feed tray, a first blocking cylinder 2231 and a second blocking cylinder 2232 are provided on both sides of the feed lifting assembly. The first blocking cylinder and the second blocking cylinder are respectively provided with a gear rod that can abut against both sides of the feed tray, a piston connected to the gear rod, an elastic member connected to the piston, and a control valve. When the feed tray needs to leave the specified position, compressed air flows into the first blocking cylinder and the second blocking cylinder through the control valve, thereby pushing the piston to move downward, thereby causing the gear rod to drop, and the feed tray is released. When the control valve releases the gas, the piston will reset under the elastic force of the elastic member, and the gear rod will rise to block the movement of the next feed tray.

[0044] like Figure 4The appearance inspection module shown in the figure, the conveying drive assembly 31 includes a first conveying track 311, a first conveying device 312 located on the first conveying track 311, a second conveying track 313 connected to the first conveying device 312, and a second conveying device 314 connected to the second conveying track 313, the first conveying track 311 is arranged in the horizontal direction, the second conveying track 313 is arranged in the vertical direction, the second conveying device 314 is provided with a variable distance assembly 3141 connected to the material picking assembly 32, the variable distance assembly 3141 can be extended or contracted in the horizontal direction, and the material picking assembly 32 is provided with an adsorption end 321 located at the lower side of the variable distance assembly 3141. Further, by combining the first conveying track and the second conveying track in the horizontal direction and the vertical direction respectively, and by using the variable distance assembly moving in the horizontal direction, the conveying drive assembly can realize the flexible transportation of materials in three-dimensional space, so that the materials can reach every corner of the inspection area more directly and efficiently. This layout makes full use of the three-dimensional space, reduces the floor space, and is particularly suitable for production environments with limited space.

[0045] Specifically, after the material moves horizontally to the predetermined position on the first conveying track, it can be vertically lifted or lowered through the second conveying track and directly sent to the next process without additional manual or mechanical handling. The seamless conveying method greatly shortens the material waiting time and improves the conveying efficiency of the entire production line.

[0046] Specifically, the variable pitch component on the second conveying device can be extended or contracted horizontally according to the specific position of the material picking component, thereby ensuring that the suction end can accurately align and adsorb the material, so that the conveying drive component can adapt to the material picking requirements of different heights and positions, and enhance the flexibility and adaptability of the production line. The precise control of the variable pitch component enables the suction end to maintain a stable posture and position during the material picking process, reducing the risk of material picking failure or material damage caused by position deviation. At the same time, the suction end ensures that the material can be firmly attached to the material picking component during the material picking process through adsorption, improving the accuracy and stability of material picking.

[0047] like Figure 5 and Figure 6 An appearance inspection module is shown, wherein the rotating mechanism accommodating tray 41 is provided with a plurality of rotating mechanism accommodating cavities 411 for the materials to extend into, and a accommodating cavity limiting portion 412 located in the rotating mechanism accommodating cavity 411 for limiting the materials, and the rotating drive assembly 42 includes a rotating shaft 421 fixedly connected to the rotating mechanism accommodating tray 41, an engaging member 422 connected to the rotating shaft 421, and a rotating drive member 423 for driving the engaging member 422 to rotate.

[0048] Furthermore, by setting up multiple rotating mechanism accommodating chambers, multiple materials can be processed simultaneously, significantly improving the efficiency of material processing. The parallel processing method reduces the time required for processing a single material, allowing the entire production line to complete tasks faster. The accommodating chamber limiter ensures the stability and accuracy of the material during the rotation process, can limit the movement range of the material, and prevent the material from shifting or tipping over during rotation, thereby ensuring the accuracy of subsequent processing or testing.

[0049] Specifically, the rotating shaft is fixedly connected to the rotating mechanism accommodating tray for transmitting the rotating power, the meshing member is connected to the rotating shaft for cooperating with the rotating driving member to transmit the rotating power, and the rotating driving member drives the meshing member to rotate, thereby driving the entire rotating mechanism to move. The rotating drive assembly realizes the automatic rotation of the material through the coordinated work of the rotating shaft, the meshing member and the rotating driving member. This automated operation not only reduces the labor intensity of the operator, but also improves the accuracy and consistency of the rotation, reduces the waiting time of the material during the processing or testing process, thereby improving the overall production speed, and avoiding errors that may be caused by human factors.

[0050] like Figure 5 and Figure 6 In the appearance inspection module shown, the material picking components 32 are symmetrically provided with two, and the rotating mechanism accommodating cavity 411 is provided with a first rotating mechanism area 4111 located in the inspection area of ​​the appearance inspection mechanism 5, a second rotating mechanism area 4112 located in the flipping area of ​​the flipping mechanism 6, and a third rotating mechanism area 4113 and a fourth rotating mechanism area 4114 respectively located at the lower sides of the two material picking components 32. Further, by setting the first rotating mechanism area in the inspection area of ​​the appearance inspection mechanism, it can be ensured that the product is correctly positioned before entering the inspection area, reducing the detection failure or repeated detection caused by improper positioning, thereby saving time and improving the detection efficiency. The second rotating mechanism area is located in the flipping area of ​​the flipping mechanism, so that the product can be accurately aligned and fixed before and after flipping, simplifying the flipping process and improving the flipping efficiency and accuracy. The third rotating mechanism area and the fourth rotating mechanism area are respectively located at the lower sides of the two material picking components. Such a layout enables the material picking component to quickly and accurately grab the product that has been adjusted by rotation, reducing the waiting time for picking up materials and improving the overall production speed.

[0051] Specifically, two symmetrically arranged material-retrieving components can work simultaneously, respectively retrieving materials from the third rotating mechanism area and the fourth rotating mechanism area, thus realizing parallel processing and greatly improving production efficiency. The material enters the inspection area of ​​the appearance inspection mechanism from the first rotating mechanism area, and after inspection, continues to rotate to enter the flipping mechanism area for flipping processing, and finally arrives at the area below the material-retrieving component to wait for material retrieval. The continuous operation process reduces the waiting time and improves the overall operation efficiency. The compact layout of multiple rotating mechanism areas and material-retrieving components makes full use of the space of the production line, reduces the floor space, and improves space utilization. The area division and material transmission path design make the transmission of materials on the production line smoother, reducing production delays caused by path intersection or congestion.

[0052] like Figure 5 and Figure 6 In the appearance inspection module shown, the midpoint of the first rotating mechanism area 4111 and the midpoint of the fourth rotating mechanism area 4114 form a first connecting line 4115, the midpoint of the second rotating mechanism area 4112 and the midpoint of the third rotating mechanism area 4113 form a second connecting line 4116, the first connecting line 4115 is parallel to the second connecting line 4116, the second connecting line 4116 is parallel to the extension direction of the first conveying track 311, and the second connecting line 4116 is perpendicular to the horizontal movement direction of the variable pitch component 3141. Further, the parallel arrangement of the first connecting line and the second connecting line makes the overall layout of the rotating mechanism accommodating cavity more coordinated and balanced, so that the equipment can be arranged compactly, reducing the space occupied by the production line. This layout helps to reduce the direction change of the material during the transmission process, so that the material can move more smoothly between various areas. Since the second connecting line is parallel to the extension direction of the first conveying track, after the material enters the rotating mechanism accommodating cavity from the first conveying track, it can be transmitted in a relatively straight direction, reducing the number of turns and changes of direction, and improving the smoothness of material transmission. The appearance detection mechanism and the first rotating mechanism region are arranged at an angle relative to the material conveying direction, which can save the space occupied by the appearance detection module. Specifically, the angle is 45-60 degrees. Preferably, the angle is 45 degrees.

[0053] In addition, the perpendicular relationship between the second connecting line and the horizontal moving direction of the pitch-changing component means that when the pitch-changing component is extended or contracted, its moving direction is perpendicular to the moving direction of the material in the rotating mechanism accommodating chamber, which helps the pitch-changing component to locate and grab the material more accurately, reducing the risk of material failure or material damage caused by directional deviation. Since the moving path of the material in the rotating mechanism accommodating chamber is relatively straight and smooth, the waiting time between each process is reduced, thereby improving the collaborative work efficiency of the entire production line.

[0054] like Figure 5and Figure 6 An appearance detection module is shown, wherein the appearance detection mechanism 5 is provided with a 360-degree lens 50, a first detection device 51 located at the lower side of the 360-degree lens 50, and an appearance detection lifting assembly 52 located at the lower side of the first detection device 51, and the first rotating mechanism area 4111 is located between the first detection device 51 and the appearance detection lifting assembly 52, and the appearance detection lifting assembly 52 is used to lift the material to the detection range of the first detection device 51. Further, by adopting a 360-degree lens, a full range of visual inspection of the material can be achieved, and every detail of the material surface can be captured without blind spots. This full range of detection method greatly improves the accuracy and comprehensiveness of the detection, and reduces the omission or misdetection caused by the limitation of the viewing angle. The appearance detection lifting assembly can automatically lift the material to the detection range of the first detection device without manual intervention. This automated operation not only improves the detection efficiency, but also reduces the errors and uncertainties caused by human factors. At the same time, it also reduces the labor intensity of the operator and improves the safety of work.

[0055] In addition, the first rotating mechanism area is arranged between the first detection device and the appearance detection lifting assembly, so that the material can quickly enter the detection area after rotating to the specified position. This layout optimizes the detection environment, reduces the time consumption and position deviation of the material during the transmission process, and improves the accuracy and stability of the detection.

[0056] Specifically, the first detection device includes a first light source 501 located at the lower side of the 360-degree lens, and a second light source 502 located at the lower side of the first light source. A plurality of evenly arranged first lamp beads are arranged on the inner side of the first light source, and the lamp beads irradiate toward the inner side of the first light source. The second light source is provided with a plurality of second lamp beads irradiating toward the upper side, and a second light source light-transmitting plate located on the upper side of the second lamp beads, and the lamp beads irradiate toward the lower side of the first light source. The use of the first light source and the second light source can improve the detection effect of the 360-degree lens.

[0057] In addition, an appearance detection adsorption end 521 for adsorbing materials is provided on the upper side of the appearance detection lifting assembly. The appearance detection adsorption end can improve the accuracy of the moving trajectory of the materials and ensure that the materials are not deflected during the movement of the appearance detection lifting assembly.

[0058] like Figure 5 and Figure 6In the appearance inspection module shown, the flip mechanism 6 includes a flip and lift assembly 61 connected to the frame 1, a rotating member 62 connected to the flip and lift assembly 61, a connecting member 63 connected to the rotating member 62 and capable of simultaneously approaching or moving away from the second rotating mechanism region 4112, and two clamping parts 64 respectively hinged on the connecting member 63, and the rotating mechanism accommodating chamber 411 is provided with an avoidance groove 4117 for the clamping parts 64 to pass through. Furthermore, the two clamping parts are connected to the rotating member through a connecting member, and can simultaneously approach or move away from the second rotating mechanism region. The synchronous clamping design ensures the stability and balance of the material during the flipping process, and avoids the material offset or dumping due to uneven force on one side.

[0059] In addition, the avoidance groove of the rotating mechanism accommodating chamber provides sufficient space for the movement of the clamping part, so that the clamping part can pass smoothly up and down and complete the flipping action, further improving the accuracy and stability of the flipping.

[0060] Specifically, the flipping and lifting assembly can automatically lift the material to a certain height, and cooperate with the rotating part to realize the flipping of the material. The entire flipping process does not require human intervention, realizing automated operation, and improving production efficiency and safety. The close connection between the flipping mechanism and the rotating mechanism accommodating cavity reduces the waiting time of the material during the flipping process and improves the overall efficiency of the production line. The compact flipping and lifting assembly and rotating part design enable the flipping action to be completed efficiently in a limited space. By making full use of the space resources on the production line, the entire system occupies a small area. The close cooperation between the flipping mechanism and the rotating mechanism accommodating cavity allows the material to quickly enter the next processing link after the flipping is completed, realizing the continuous operation of the production line.

[0061] like Figure 1 and Fig.15 As shown, further, after the feed tray leaves the detection area, the feed tray moves to the sorting area under the push of the material conveying mechanism, and a third blocking cylinder and a fourth blocking cylinder are provided at both ends of the sorting area, and the third blocking cylinder and the fourth blocking cylinder are respectively provided with a gear rod that can abut against both sides of the feed tray, a piston connected to the gear rod, an elastic member connected to the piston, and a control valve. When the feed tray needs to leave the specified position, compressed air flows into the third blocking cylinder and the fourth blocking cylinder through the control valve, thereby pushing the piston to move downward, and then causing the gear rod to drop, and the feed tray is released. When the control valve releases the gas, the piston will reset under the elastic force of the elastic member, and the gear rod will rise to block the movement of the next feed tray.

[0079] Specifically, the material is elliptical in shape, and the upper surface and the lower surface need to be detected during detection.

[0080] Specifically, the materials to be tested are first placed in the four tray accommodating cavities of the feed tray, recorded as material 1, material 2, material 3, and material 4. The feed tray containing the materials is transported to the detection area along the conveying bracket through the feed conveyor line. The tray limiter abuts against the conveying bracket limiter to ensure the stability of the position of the feed tray during the conveying process and avoid the displacement of the material position due to shaking. When the feed tray reaches the specified position, the feed lifting assembly is started to lift the feed tray and move it toward the direction of the material picking assembly. After the feed tray is lifted into place, the tray limiter abuts against the conveying bracket limiter, and the material picking assembly takes the material out of the tray accommodating cavity through the adsorption end, and moves horizontally to the upper side of the rotating mechanism through the first conveying track, and the variable pitch assembly extends horizontally. At the same time, the second conveying track is used to move vertically to the upper side of the rotating mechanism accommodating tray, and the adsorption end transfers the material to the rotating mechanism accommodating cavity.

After the appearance inspection mechanism completes the inspection, it records the appearance of the upper surface of the material, and the appearance inspection lifting assembly descends to place the material back in the rotating mechanism accommodating cavity.

[0082] S3, the rotating mechanism 4 rotates, the material moves to the flipping area of ​​the flipping mechanism 6, the flipping mechanism 6 flips the material, the material conveying mechanism 3 transfers the material to the rotating mechanism 4, until the flipped material moves back to the detection area of ​​the appearance detection mechanism 5, and the appearance detection mechanism 5 detects the appearance of the other side of the material and records it; Specifically, after inspection, the material continues to rotate and enter the flipping mechanism area for flipping processing. The other side of the material is flipped to other positions that will be detected by the appearance inspection mechanism. The rotating mechanism rotates to the area below the material picking component to wait for material picking. At this time, the system will determine that the inspection of the upper surface of the material has been completed. When the remaining side surfaces of the material, that is, the lower surface, have not been inspected, the material picking component stops picking up the material, and the rotating mechanism continues to rotate. The material is moved back to the inspection area of ​​the appearance inspection mechanism, and the appearance inspection mechanism inspects the appearance of the other side of the material, that is, the lower surface, and records it.

[0083] S4, the rotating mechanism 4 rotates, and the material moves to the turning area of ​​the turning mechanism 6. The turning mechanism turns the material over. When all sides of the material are detected, the material conveying mechanism 3 transfers the material to the feeding tray 21.

[0084] Specifically, after detection, the material continues to rotate and enter the flipping mechanism area for flipping. The lower surface of the material is flipped. At this time, the upper surface of the material will be detected by the appearance detection mechanism. The rotating mechanism rotates to the area below the material picking component to wait for material picking. At this time, the system will determine that the detection of the lower surface of the material has been completed. When all surfaces of the material have been detected, the material picking component starts to pick up the material and transfers the material to the feeding tray.

[0085] S5. When the feeding tray moves to the sorting area, the sorting area is equipped with a barcode scanning component to scan the tray barcode of the feeding tray. When the system records that material 3 in the feeding tray with number 1 is a defective product, the sorting component transfers the recorded defective material 3 to the defective product area, and then transfers the qualified materials 1, 2, and 4 to the finished product area. The defective product area and the finished product area are located on the sorting tray, and the moving direction of the sorting tray is perpendicular to the moving direction of the feeding tray, which can further save space.
