Description

Technical Field

[0001] This invention relates to the field of automated inspection equipment technology, and in particular to an automated production line and method for product size measurement and AOI inspection. Background Technology

[0002] During product manufacturing, it is typically necessary to inspect the product's dimensional parameters and surface appearance to determine whether the product meets preset quality requirements. Dimensional inspection is mainly used to obtain parameters such as the product's length, width, thickness, or outline dimensions, while AOI inspection mainly uses image acquisition and analysis to determine whether there are appearance defects on the product surface, such as scratches, dirt, defects, or assembly abnormalities.

[0003] In existing production lines, dimensional measurement equipment and AOI (Automated Optical Inspection) equipment are typically set up separately. After dimensional measurement, products need to be transferred, repositioned, or reloaded before entering the AOI equipment for appearance inspection. Multiple pick-up and transfer of products between different inspection devices not only increases intermediate transport links but also easily affects the inspection cycle time and the continuity of the entire line. Furthermore, products are usually transported along the conveyor line by carriers, but during AOI inspection, products often need to be removed from the carriers and transferred to independent inspection positions. When the carrier enters the AOI inspection area with the product, the carrier may occupy space for both inspection and product transfer; when the carrier is idle or handled separately in other ways, it can easily cause a mismatch between the cycle time of carrier transport and product inspection, affecting the continuous operation of the automated production line. Therefore, an automated production line for product dimensional measurement and AOI inspection is proposed to solve the above problems. Summary of the Invention

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] The following is in conjunction with the appendix Figure 1 - Appendix Figure 11 The present invention will be further described in detail below.

[0023] Reference Figure 1 , Figure 2 , Figure 5 and Figure 11 The present invention provides an automated production line for product size measurement and AOI inspection, including a carrier conveying assembly 1, a size measurement and transfer assembly 2, at least one size measurement assembly 3, an AOI diversion and transfer assembly 4, a positioning assembly 5, a product transfer device 6, at least one AOI inspection assembly 7, a flow processing assembly 8, and a control assembly 9. The carrier conveyor assembly 1 forms a carrier conveyor path that sequentially passes through a dimensional measurement station, an image acquisition station, an AOI splitting station, a carrier bypass section, and a merging station. After the product and carrier separate at the AOI splitting station, the product enters the AOI inspection area along the product inspection path, while the carrier bypasses the AOI inspection area along the carrier bypass section. The product to be tested is carried in the carrier and passes through different inspection and processing stations sequentially along the carrier conveyor path. The dimension measurement transfer assembly 2 is used to transfer the product from the carrier to the dimension measurement assembly 3, where the dimension measurement assembly 3 measures the product's dimensions, and then returns the product to the original carrier after measurement. The AOI diversion transfer assembly 4 is used to separate the product from the carrier at the AOI diversion station, the positioning assembly 5 is used to define the product's position and orientation, and the product transfer device 6 is used to send the positioned product into the AOI inspection assembly 7 for appearance inspection. After the product is separated from the carrier, the carrier bypasses the AOI inspection area along the carrier bypass section, thereby reducing the carrier's occupation and interference with the working space of the AOI inspection component 7 and the product transfer device 6. The product that has completed AOI inspection rejoins the bypassed carrier and is transported to the convergence station with the carrier; The confluence processing component 8 performs qualified loading or abnormal diversion of the products that have completed inspection according to the processing instructions output by the control component 9; the control component 9 generates the processing instructions based on the dimensional measurement results and the appearance inspection results. As a result, the product can complete dimensional measurement and AOI inspection sequentially on the same carrier transport path, and be loaded into qualified or diverted from abnormal based on the comprehensive inspection results.

[0024] Reference Figure 1 , Figure 2 , Figure 7 , Figures 9 to 11 The carrier conveying assembly 1 includes multiple carrier conveying sections 28 arranged along the product inspection process; the multiple carrier conveying sections 28 are interconnected to form a carrier conveying path for the carrier to move from the dimensional measurement station to the confluence station; The vehicle transport assembly 1 is provided with multiple obstruction detection units 40 at intervals along the vehicle transport path. (Refer to...) Figure 10 Each blocking detection unit 40 includes a switchable blocking component 26 and a position detection component 27 corresponding to the switchable blocking component 26; The arrival detection component 27 is used to detect whether the carrier has reached the corresponding workstation or the predetermined position. Based on the arrival signal output by the arrival detection component 27, the control component 9 controls the corresponding switchable blocking component 26 to switch between blocking and releasing states. When the carrier arrives at the corresponding workstation and needs to stop for processing, the switchable blocking component 26 switches to the blocking state to restrict the carrier from continuing to move; when the corresponding workstation completes processing and allows the carrier to continue transporting, the switchable blocking component 26 switches to the releasing state. Multiple obstruction detection units 40 can be respectively set at the size measurement station, image acquisition station, AOI diversion station, vehicle detour section and merging station, etc., to realize the positioning, waiting and orderly release of the vehicle at different stations.

[0025] Reference Figure 1 , Figure 2 and Figure 4 The dimension measurement and transfer component 2 is disposed at the dimension measurement station. The dimension measurement and transfer component 2 includes a first robot 32 and a first pick-and-place part 33 disposed at the end of the first robot 32. The first robot 32 can drive the first pick-and-place unit 33 to move between the carrier loading position and the dimension measuring component 3. After the carrier arrives at the dimension measuring position, the corresponding blocking detection unit 40 restricts the carrier at the carrier loading position. The first pick-and-place unit 33 takes out the product to be measured from the carrier and, driven by the first robot 32, places the product at the measuring position of the dimension measuring component 3; The dimension measurement component 3 measures at least one of the product's length, width, thickness, outline dimensions, hole dimensions, or other preset dimension parameters, and sends the obtained dimension measurement results to the control component 9. After the dimension measurement is completed, the first robot 32 drives the first pick-and-place unit 33 to remove the product from the dimension measurement component 3 and place it back into the corresponding carrier; The first pick-and-place section 33 can adopt pick-and-place methods such as adsorption, clamping, or a combination of adsorption and clamping, depending on the shape, material, and surface condition of the product.

[0026] Reference Figure 2 and Figure 3 An image acquisition and transfer component 10 is provided between the downstream of the dimensional measurement station and the upstream of the AOI diversion station. The image acquisition and transfer component 10 includes a transverse carrying component 11, a transverse driving component 12, at least one product pick-and-place component 13, a first identification reading component 14, and an image acquisition component 15. The transverse driving component 12 is connected to the transverse carrying component 11 and is used to drive the transverse carrying component 11 to move between the carrier pick-and-place position, the identification reading position, and the image acquisition position. The product pick-and-place component 13 is disposed on the transverse carrying component 11 and is used to remove the product from the carrier or put the product back into the carrier. The first identification reading component 14 and the image acquisition component 15 are set on the moving path of the product picking and placing component 13. After the carrier arrives at the image acquisition station, the product picking and placing component 13 takes out the product from the carrier and passes through the identification reading position and the image acquisition position in sequence with the transverse carrier component 11. When the product arrives at the identification reading position, the first identification reading component 14 reads the product's QR code, barcode, character code or other identifiable identification, and sends the first identification reading result to the control component 9. When the product arrives at the image acquisition position, the image acquisition component 15 acquires the image of the product's preset area, and sends the corresponding image acquisition result to the control component 9. Along the transport direction of the carrier, a front-end abnormal receiving component 23 is provided downstream of the image acquisition and transfer component 10. The control component 9 judges the first identification reading result and the image acquisition result. When both the identification reading result and the image acquisition result meet the corresponding preset conditions, the control component 9 controls the product pick-and-place component 13 to put the product back into the carrier. When the identification reading fails, the identification information does not match, the image acquisition fails, or at least one result does not meet the corresponding preset conditions, the control component 9 outputs a front-end abnormal diversion command, causing the product pick-and-place component 13 to transfer the corresponding product to the front-end abnormal receiving component 23. The front-end anomaly receiving component 23 is used to centrally receive abnormal products that have not yet entered the AOI inspection work area, thereby preventing products with abnormal identification or image acquisition from continuing to enter subsequent inspection stations.

[0027] Reference Figure 2 , Figure 5 , Figure 7 and Figure 8 The AOI diversion and transfer component 4 is set at the AOI diversion station. The AOI diversion and transfer component 4 includes a second robot 34, and a diversion product pick-up and place part 35 and a diversion carrier pick-up and place part 36 respectively set at the end of the second robot 34. After the product-carrying carrier arrives at the AOI sorting station, the second robot 34 first removes the product from the carrier via the product sorting pick-and-place section 35 and transfers the product to the positioning component 5. Subsequently, the second robot 34 picks up and places the carrier separated from the product via the carrier sorting pick-and-place section 36 and transfers the carrier to the carrier bypass section; The positioning component 5 includes a pre-inspection positioning component 16 and a pre-reassembly positioning component 17. The pre-inspection positioning component 16 is located between the AOI diversion station and the AOI inspection component 7, and is used to define the position and orientation of the product before it enters the AOI inspection component 7. The pre-reassembly positioning component 17 is located downstream of the AOI inspection component 7 and upstream of the product loading station, and is used to define the position and orientation of the product before it is loaded into the output carrier. The pre-detection positioning component 16 includes a positioning structure for defining the position and orientation of the product, the positioning structure including at least one of a positioning surface, a positioning pin, a limiting block, a clamping member, and an adsorption member.

[0028] Reference Figure 5 and Figure 6The product transfer device 6 includes at least one third robot 37 and an attitude conversion component 18 disposed at the end of the third robot 37. The third robot 37 can be a multi-axis robot capable of driving the product to move in multiple directions. The attitude conversion assembly 18 includes an AOI product pick-and-place section 38 and a rotary drive section 39 connected to the AOI product pick-and-place section 38. The AOI product pick-and-place section 38 is used to pick up and place products, and the rotary drive section 39 is used to drive the AOI product pick-and-place section 38 and the products held by the AOI product pick-and-place section 38 to rotate or flip. After the pre-inspection positioning component 16 completes product positioning, the third robot 37 retrieves the product through the AOI product pick-and-place unit 38 and sends the product into the inspection area of ​​the AOI inspection component 7. The AOI inspection component 7 uses an industrial camera, light source, and corresponding image processing device to acquire images of the product surface and make appearance judgments to obtain the appearance inspection results of the product. During the inspection process, the rotary drive unit 39 drives the AOI product pick-and-place unit 38 to rotate or flip between at least two inspection postures, enabling the AOI inspection assembly 7 to inspect different surfaces or different inspection areas of the product. After the appearance inspection is completed, the third robot 37 removes the product from the AOI inspection assembly 7 and rejoins the product with the carrier that bypasses the AOI inspection work area.

[0029] Reference Figures 7 to 10 The vehicle bypass section includes at least two vehicle transport sections 28 and at least one vehicle transfer assembly 19 disposed between two adjacent vehicle transport sections 28; the vehicle transfer assembly 19 includes a lateral vehicle pick-up and place section 24 and a vehicle transfer drive assembly 25, the vehicle transfer drive assembly 25 being connected to the lateral vehicle pick-up and place section 24 and used to drive the lateral vehicle pick-up and place section 24 to transfer between at least two vehicle transport sections 28; When the carrier separated from the product reaches the carrier transfer position, the corresponding arrival detection component 27 detects that the carrier has arrived. The control component 9 controls the corresponding switchable blocking component 26 to block the carrier and controls the transverse carrier pick-and-place unit 24 to pick up the carrier. Subsequently, the carrier transfer drive component 25 drives the transverse carrier pick-and-place unit 24 to move, transferring the carrier from one carrier transport section 28 to another carrier transport section 28. Through the cooperation of multiple carrier transport sections 28 and carrier transfer components 19, the carrier bypasses the AOI inspection work area where the AOI inspection component 7 and the third robot 37 are located, and is transported to the product converging position to wait for the products that have completed AOI inspection to be put back. This carrier bypass method enables the product to be independently inspected in multiple poses within the AOI inspection area, while allowing the carrier to continuously transport along a predetermined path, reducing the impact of the carrier on the motion space of the third robot 37 and the inspection space of the AOI inspection component 7.

[0030] Reference Figure 1 , Figure 2 , Figure 5 and Figure 11 The confluence processing component 8 is located downstream of the carrier conveying path. The confluence processing component 8 includes a carrier stacking mechanism 29, an output carrier feeding mechanism 30, at least one end transfer device 31, and an end abnormality receiving component 20. After the product that has completed AOI inspection rejoins the rerouted carrier, the carrier continues to transport the product to the end-of-line processing station. The end-of-line transfer device 31 removes the product from the carrier, separating the product from the carrier again, and transfers the empty carrier to the carrier stacking mechanism 29. The carrier stacking mechanism 29 is used to receive and store the carrier after it has been separated from the product. The end-of-line transfer device 31 transfers the product to the pre-reloading positioning component 17. The pre-reloading positioning component 17 limits the position and orientation of the product before it is loaded into the output carrier, so that the product can be loaded into the output carrier provided by the output carrier feeding mechanism 30 in a predetermined orientation. The control component 9 determines whether the product meets the qualified loading conditions based on the corresponding size measurement results and appearance inspection results; the end transfer device 31 transfers the product to the output carrier or the end abnormal receiving component 20 according to the qualified loading command or end abnormal diversion command output by the control component 9.

[0031] In this embodiment, the automated production line is equipped with at least three barcode scanning stations along the conveying path of the product and the carrier. The three barcode scanning stations acquire the corresponding identification information through the first identification reading component 14, the second identification reading component 21, and the third identification reading component 22, respectively. The first identification reading component 14 is set at the image acquisition station and is used to perform the first identification reading on the product taken out by the product pick-up and place component 13. The second identification reading component 21 is set at the pre-reassembly positioning component 17 and is used to read the identification information of the product again before the product is loaded into the output carrier to verify the product identity and its corresponding inspection record. The vehicle transport assembly 1 has an end transport section 41 located at the output end. The third identification reading assembly 22 is disposed below the end transport section 41 and is positioned toward the vehicle passing through the end transport section 41. The third identification reading assembly 22 is used to read vehicle identification information and send the vehicle identification reading result to the control assembly 9. The control component 9 establishes, verifies, or updates the inspection record corresponding to the corresponding product based on the scanning information obtained sequentially from each scanning station, and in combination with at least one of the scanning count information and conveying sequence information. The inspection record includes at least one of the following: product identification information, carrier identification information, inspection results, conveying sequence, and diversion results.

[0032] Specifically, the control component 9 is communicatively connected to the dimension measurement transfer component 2, dimension measurement component 3, AOI diversion transfer component 4, positioning component 5, product transfer device 6, AOI detection component 7, convergence processing component 8, image acquisition transfer component 10, first identification reading component 14, second identification reading component 21, third identification reading component 22, carrier transfer component 19, and each obstruction detection unit 40. The control component 9 may include at least one of a programmable controller, an industrial computer, a data storage module, and a communication module. The control component 9 controls actions such as carrier conveying, product picking and placing, product positioning, posture conversion, carrier detouring, qualified loading, and abnormal diversion based on the arrival detection signal, barcode information, dimension measurement results, appearance inspection results, and the action status of each actuator. When both the dimensional measurement results and the appearance inspection results meet the corresponding qualification conditions, the control component 9 will determine the corresponding product as a qualified product and output a qualified loading command; when at least one of the dimensional measurement results or the appearance inspection results does not meet the corresponding qualification conditions, the control component 9 will determine the corresponding product as a non-qualified product and output an end abnormal diversion command.

[0033] This invention also provides a product size measurement and AOI inspection method, which can be implemented using the above-mentioned automated production line, and includes the following steps: S1. Size Measurement: The carrier carrying at least one product to be measured is transported to the size measurement station by the carrier transport component 1. The product to be measured is transferred from the carrier to the size measurement component 3 by the size measurement transfer component 2 for size measurement, and the size measurement result is obtained. After the size measurement is completed, the product is put back into the carrier.

[0034] S2. Product and carrier separation and AOI inspection: The carrier is transported to the AOI separation station. The product is separated from the carrier by the AOI separation transfer component 4. The product is positioned by the positioning component 5. The product is transferred to the AOI inspection component 7 by the product transfer device 6 for appearance inspection and to obtain the appearance inspection results. At the same time, the carrier separated from the product is made to bypass the AOI inspection operation area along the carrier bypass path.

[0035] S3. Maintaining the association between the product and the inspection results: During the separation, inspection and reassembly of the product and the carrier, the control component 9 maintains the association between the dimensional measurement results and the appearance inspection results and the corresponding product based on at least one of the identification information, counting information and conveying sequence information; after the AOI inspection is completed, the product is reassembled with the carrier that bypasses the AOI inspection work area.

[0036] S4. Convergence and Diversion Processing: The product is transported to the convergence station via the carrier conveyor assembly 1. The control assembly 9 generates a qualified loading instruction or an abnormal diversion instruction based on the dimensional measurement results and appearance inspection results associated with the product. The convergence processing assembly 8 loads the product into the output carrier according to the qualified loading instruction, or transfers the product to the end abnormal receiving assembly 20 according to the abnormal diversion instruction.

[0037] Working principle During the operation of the automated production line, the carrier conveyor assembly 1 sequentially transports the carriers carrying products to the dimensional measurement station, the image acquisition station, and the AOI sorting station. The dimensional measurement transfer assembly 2 transfers the products to the dimensional measurement assembly 3 for dimensional measurement and then returns them to the carrier; the image acquisition transfer assembly 10 reads the product's identification and acquires images, and transfers any abnormal products from the previous stage to the previous stage abnormal receiving assembly 23. After the carrier arrives at the AOI diversion station, the AOI diversion and transfer component 4 separates the product from the carrier. The product is positioned by the pre-inspection positioning component 16 and then sent by the product transfer device 6 to the AOI inspection component 7 for appearance inspection. The carrier separated from the product bypasses the AOI inspection area along the carrier bypass section. After completing the AOI inspection, the product rejoins the bypassed carrier and is transported to the final processing station. Based on the dimensional measurement results and appearance inspection results associated with the product, the control component 9 controls the convergence processing component 8 to load qualified products into the output carrier, or to transfer unqualified products to the final abnormality receiving component 20.
