Description

Technical Field

[0001] This invention belongs to the field of display inspection technology, and particularly relates to an AOI inspection device, panel inspection equipment and method. Background Technology

[0002] In the manufacturing process of various display panels such as TFT, LTPS, and AM-OLED, optical inspection of the display panels is required to check for defects such as color unevenness (mura) and bright / dark spots.

[0003] AOI (Automatic Optical Inspection) is a device that uses optical principles to detect surface defects in materials under inspection. Automation of production equipment is a crucial indicator of the level of automation in a production line and a vital guarantee of product quality and performance.

[0004] Typically, during AOI inspection of LCD screens, the product needs to remain in a dotted state to obtain more accurate inspection results. However, existing AOI inspection devices usually use multiple different robotic arms to move the product under test between different mechanisms, which is complex, has low inspection efficiency, and makes it difficult to ensure that the product under test remains in a dotted state during AOI inspection.

[0005] Therefore, there is a need to develop an AOI inspection device that can reduce the use of handling mechanisms while improving equipment operating efficiency, and that can provide continuous power to the product while it is undergoing AOI inspection. Summary of the Invention

[0006] In view of all or part of the deficiencies of the prior art described above, the purpose of this invention is to provide an AOI inspection device (automatic optical inspection equipment) that uses a toothed fork to transfer the product to be tested between different mechanisms, reducing interference from the external environment and human intervention in product inspection, while enabling continuous screen display of the product during AOI inspection; another purpose is to provide an AOI inspection method that enables high-efficiency operation of loading, unloading, AOI inspection, and unloading of the product to be tested.

[0007] To achieve the above-mentioned objectives, the present invention provides the following technical solution: an AOI inspection device, characterized in that it includes a receiving mechanism, at least one AOI inspection mechanism, and at least one insertion / removal mechanism; the receiving mechanism is disposed between the loading mechanism and the unloading mechanism; the insertion / removal mechanism includes at least one moving unit, the moving unit including a mounting frame and an insertion / removal fork disposed on the mounting frame; the insertion / removal fork receives the product to be tested from the receiving mechanism and drives the product to be tested to move between the insertion / removal station and the AOI inspection mechanism. The beneficial effects of this technical solution are that by arranging the receiving mechanism, the insertion / removal mechanism, and the AOI inspection mechanism in the same device, the entire process of insertion / removal and AOI inspection of the product to be tested is automated, reducing the use of handling mechanisms and reducing manual contact with the product during the inspection process; simultaneously, the layout design of the insertion / removal mechanism, the AOI inspection mechanism, and the receiving mechanism improves space utilization and equipment operating efficiency.

[0008] The receiving mechanism further includes a receiving moving component, and the receiving tooth fork is disposed on the receiving moving component; the receiving tooth fork is provided with a receiving suction cup for adsorbing the product to be tested; the receiving moving component includes a motor mounting bracket and a first driving component fixedly mounted on the motor mounting bracket.

[0009] Furthermore, the first driving component is a linear motor, which includes two moving parts and a stator, with the two moving parts disposed at both ends of the stator; the receiving fork includes a first receiving fork and a second receiving fork, which are respectively fixedly connected to the two moving parts. By setting up a linear motor and having the first and second receiving forks respectively disposed on the moving parts at both ends of the linear motor, different receiving forks are used to complete the loading and unloading of products, separating the loading and unloading processes of the products to be tested, reducing the cycle time of other mechanisms waiting, and improving the operating efficiency of the equipment.

[0010] The mounting frame is equipped with a first movable component, on which a mounting base is slidably connected. A second driving component is fixedly mounted on the mounting base. The insertion / extraction fork is fixedly connected to the output end of the second driving component. The insertion / extraction fork is equipped with a vacuum suction cup and a current collector for adsorbing the product under test. The advantages of this technical solution are that by setting a movable component on the insertion / extraction mechanism, the insertion / extraction fork can move the product between the insertion / extraction station and the AOI inspection mechanism, achieving the purpose of product handling. Simultaneously, by fixing the output ends of the insertion / extraction fork and the second driving component, the second driving component can drive the insertion / extraction fork to perform lifting and lowering movements, allowing the insertion / extraction fork to operate at different heights, providing the possibility of using multiple insertion / extraction forks to handle products. Furthermore, the current collector on the insertion / extraction fork enables continuous screen scanning of the product under test after wiring, ensuring the effectiveness of AOI inspection.

[0011] Furthermore, the insertion / removal mechanism includes two parallel moving units; the insertion / removal forks of the two moving units are slidably connected to the two first moving parts respectively. By setting two moving units in the insertion / removal mechanism, and setting the two insertion / removal forks facing each other in the two moving units, the alternating use of the two insertion / removal forks can be realized, effectively improving the operating efficiency of the equipment.

[0012] The device includes two insertion / removal mechanisms and two AOI (Automated Optical Inspection) mechanisms. The two insertion / removal mechanisms and the two AOI mechanisms are arranged side-by-side, with each insertion / removal mechanism corresponding to one AOI mechanism. By incorporating two insertion / removal mechanisms and two AOI inspection mechanisms into the inspection device, multiple products can be inspected simultaneously, further improving product inspection efficiency.

[0013] The AOI inspection device also includes a loading mechanism, which comprises a loading unit, a barcode reader for reading product information, and an alignment component. The loading unit includes a loading fork and a loading moving component disposed thereunder. The loading moving component drives the loading fork to move. By incorporating a barcode reader in the loading mechanism to read the product information under test, subsequent recording is facilitated. The precise transfer of the product under test is achieved through the moving component and alignment component, thereby improving the accuracy of subsequent AOI inspection.

[0014] The alignment component is fixedly configured on one side of the feeding mechanism, and includes an alignment motor and two alignment cameras. The alignment motor drives the two alignment cameras to move in opposite directions or towards each other. By setting two alignment cameras in the alignment component and driving the two alignment cameras to move in opposite directions or towards each other through a second servo motor, the alignment requirements of products of different sizes can be met.

[0015] The AOI inspection mechanism also includes a fixed fork and an AOI optical assembly disposed above it for product inspection. The fixed fork is equipped with a fixed fork suction cup for adsorbing the product and a sensor for sensing the product. By using a fixed fork in the AOI inspection mechanism to place the product under test and keep it stable during inspection, the inspection results are improved. The fixed fork suction cup and sensor on the fixed fork achieve the above objectives. The AOI optical assembly completes the product inspection.

[0016] Furthermore, the fixed tooth fork includes a plurality of forks and a plurality of fixed tooth fork suction cups.

[0017] A panel inspection device is provided, comprising the aforementioned AOI inspection apparatus. Utilizing the aforementioned AOI inspection apparatus in the panel inspection device can effectively improve the efficiency of panel inspection.

[0018] An AOI (Automated Optical Inspection) method includes the following steps: S1: The feeding fork in the feeding mechanism picks up the product to be tested after code reading and alignment, and places it on the insertion / removal fork of the insertion / removal mechanism; S2: The insertion / removal fork moves the product to be tested to the insertion / removal station for wire insertion. The insertion / removal fork receiving the product after insertion interlocks with the fixed fork, transferring the product to the fixed fork, and performing optical inspection on the product using AOI optical components; S3: The insertion / removal fork picks up the product placed on the fixed fork and, after inspection, moves it to the insertion / removal station for wire removal. The beneficial effect of this technical solution is that the above process achieves efficient and orderly execution of the entire process of product loading, wire insertion, AOI inspection, wire removal, and unloading, effectively improving inspection efficiency.

[0019] Step S2 includes: S21, after receiving the product to be tested, the insertion / removal fork rises to the operating height and moves to the insertion / removal station while maintaining the height; the insertion / removal fork then descends to the insertion / removal height to insert wires into the product to be tested; S22, after receiving the product with inserted wires, the insertion / removal fork rises to the operating height and moves to the AOI inspection mechanism while maintaining the height; the insertion / removal fork descends below the fixed fork, transferring the product onto the fixed fork; the insertion / removal fork remains stationary until the product completes AOI inspection. The beneficial effect of this technical solution is that by using a second servo motor to drive the insertion / removal fork to move up and down, the insertion / removal fork can operate at different heights, thereby achieving the goal of setting two insertion / removal forks in the same insertion / removal mechanism, and allowing each fork to operate independently. This effectively shortens the insertion / removal time required for the product to be tested, reduces the waiting time of other mechanisms, and improves the overall operating efficiency of the equipment.

[0020] Compared with the prior art, the present invention has at least the following beneficial effects: 1) By setting the loading mechanism, unloading mechanism, receiving mechanism, insertion and removal mechanism, and AOI inspection mechanism in the same equipment, the entire process of loading, insertion and removal, AOI inspection, and unloading of the product to be tested is automated, reducing the use of handling mechanisms and reducing manual contact with the product during the inspection process; 2) By setting the receiving mechanism between the loading and unloading mechanisms, and setting the insertion and removal mechanism and AOI inspection mechanism parallel to the receiving mechanism, this unique layout improves space utilization and equipment operating efficiency; 3) By setting on the insertion and removal tooth fork... The current collector box enables continuous screen illumination of the product under test after wiring is performed, ensuring the effectiveness of AOI inspection; 4) By setting a second driving component to drive the insertion and removal fork to move up and down, the insertion and removal fork can operate at different heights, thereby achieving the goal of setting two insertion and removal forks in the same insertion and removal mechanism and enabling each fork to operate independently, effectively shortening the time required for insertion and removal of the product under test, reducing the waiting time of other mechanisms, and improving the overall operating efficiency of the equipment; 5) Through the above methods, the entire process of loading, wiring, AOI inspection, wire removal, and unloading of the product under test is carried out efficiently and orderly, effectively improving the inspection efficiency.

Detailed Implementation

[0035] The technical solutions in specific embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. 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.

[0036] Example 1

[0037] This embodiment provides an AOI detection device, such as Figure 1 and Figure 2 As shown, this equipment includes a feeding mechanism 1, a receiving mechanism 2, an insertion / removal mechanism 3, an AOI inspection mechanism 4, and a discharging mechanism 5. Specifically, as... Figure 3 As shown, the feeding mechanism 1 includes a feeding unit. Above the junction of the feeding mechanism 1 and the receiving structure, a code reader 62 and an alignment component 61 are also provided. The feeding unit includes a feeding fork 101 and a moving component disposed below it. The feeding fork 101 is equipped with feeding suction cups 1011 for adsorbing the product to be tested. The feeding suction cups 1011 are arranged in rows of three on the feeding fork 101. Figure 4As shown, the moving component includes a θ-axis 111, an X-axis 112, and a Z-axis 113 arranged sequentially from top to bottom, and the three are slidably connected to each other. The loading fork 101 is fixedly connected to the θ-axis 111, and the upstream process places the product to be tested on the loading fork 101. The barcode reader 62 is fixedly installed on the mounting bracket 6 above the intersection of the loading fork 101 and the receiving fork. When the product to be tested placed on the loading fork 101 moves to this point, the barcode reader 62 reads the code of the product to be tested for subsequent recording of product information. After the code is read, the loading fork 101 completes the alignment with the alignment component 61 and the moving component (which achieves position correction through the movement of the θ-axis 111, X-axis 112, and Z-axis 113), realizing the precise handshake between the loading fork 101 and the receiving fork to complete the step of transferring the product to be tested from the loading fork 101 to the receiving fork. Specifically, the alignment component 61 is mounted on the mounting bracket 6 above the receiving fork, such as... Figure 5 As can be seen, the alignment component 61 includes an alignment motor 612 and an alignment camera. More specifically, an alignment camera is provided on each of the left and right sides of the alignment component, namely a left alignment camera 610 and a right alignment camera 611. The alignment motor 612 can drive the alignment camera to move horizontally along the camera guide rail 613, so that the left and right alignment cameras can move towards each other or in opposite directions to meet the alignment requirements of products of different sizes. One side of the camera guide rail 613 is provided with an alignment drag chain 614 for accommodating the line.

[0038] In this embodiment, the receiving mechanism 2 is disposed between the loading mechanism 1 and the unloading mechanism 5. Specifically, it is composed of... Figure 6 and Figure 7 As can be seen, the receiving mechanism 2 includes a moving component and a receiving fork. More specifically, in this embodiment, the moving component includes a linear motor mounting bracket 204 and a linear motor 205. The linear motor 205 includes a stator and two movers, which are distributed at both ends of the stator. The timing and path of its operation are controlled by an encoder according to a pre-set program. The receiving fork includes a first receiving fork 201 for receiving the product to be tested from the feeding fork 101 and a second receiving fork 202 for unloading the tested product. The first receiving fork 201 is fixedly mounted on the mover near the feeding mechanism 1, and the second receiving fork 202 is fixedly mounted on the mover near the unloading mechanism 5. Linear motor 205 drives the first receiving fork 201 to reciprocate between the loading mechanism 1 and the insertion / removal mechanism 3, and drives the second receiving fork 202 to reciprocate between the insertion / removal mechanism 3 and the unloading mechanism 5. The movements of the first receiving fork 201 and the second receiving fork 202 are independent of each other, achieving loading and unloading using the same mechanism while ensuring that the loading and unloading processes do not interfere with each other, making the equipment operation more orderly and efficient. Of course, in some embodiments, other driving components that can achieve the purpose of this invention can be used as moving components, such as a combination of two separate stepper motors.

[0039] Furthermore, the stator of the linear motor 205 is equipped with a dust cover for dust prevention, and the receiving fork is fixedly connected to the mover via a fork fixing plate. In addition, in this embodiment, the receiving fork includes six receiving forks 21, with the two middle receiving forks 21 in close contact without gaps. Each of these two receiving forks is equipped with three receiving suction cups 22 for adsorbing the product to be tested placed thereon. Of course, in other embodiments, the number and position of the receiving suction cups 22 can be set according to requirements and are not limited here.

[0040] After receiving the product to be tested, the first receiving fork 201 moves to the insertion / removal mechanism 3 under the drive of the mover. The product is then transferred to the insertion / removal fork 33 through the interaction between the first receiving fork 201 and the insertion / removal fork 33. Specifically, by... Figure 8-10 It is known that the insertion / removal mechanism 3 includes a moving unit and an insertion / removal toothed fork 33. The insertion / removal toothed fork 33 is equipped with an insertion / removal suction cup 331 and a current collector box 330. In this embodiment, the insertion / removal mechanism 3 is provided with two moving units, each of which is equipped with an insertion / removal toothed fork 33. The insertion / removal toothed fork 33 includes six insertion / removal forks 332, which are arranged equidistantly and parallelly. Three insertion / removal suction cups 331 for picking up the product to be tested are provided on each of the two middle insertion / removal forks. Specifically, the moving unit includes a mounting frame 30 and a long-distance slide 31 disposed thereon. The second driving member is slidably connected to the slide 31 through a mounting base 320. The insertion / removal toothed fork 33 is fixedly connected to the output end of the second driving member. The second driving member can drive the insertion / removal toothed fork 33 to perform lifting and lowering movements. In this embodiment, the second driving component is a lifting motor 32. However, in other embodiments, a lifting cylinder or other lifting elements can also be used as the driving component to drive the insertion / removal tooth fork 33 for lifting and lowering. The insertion / removal tooth fork 33 of the insertion / removal mechanism 3 includes a first insertion / removal tooth fork 301 and a second insertion / removal tooth fork 302. The slide table 31 includes slide table I and slide table II. Slide table I and slide table II are arranged parallel to each other on their respective mounting brackets 30 (of course, in the case of multiple insertion / removal mechanisms 3, two slide tables 31 can share one mounting bracket 30, as detailed below). Figure 9 As shown), the No. 1 insertion / extraction tooth fork 301 is located on the right side of slide I, and the No. 2 insertion / extraction tooth fork is located on the left side of slide II. This arrangement allows the No. 1 insertion / extraction tooth fork 301 and the No. 2 insertion / extraction tooth fork 302 to operate independently without interfering with each other.

[0041] In this embodiment, as Figure 11As shown, after the loading fork 101 receives the product to be tested, the No. 1 insertion / removal fork 301 moves to the handover station under the drive of the slide table I. When the loading fork 101 moves to this position under program control, the No. 1 insertion / removal fork 301 rises to the hand-holding height 321 under the drive of the lifting motor 32. Then, the No. 1 insertion / removal fork 301 and the first receiving fork 201 hold each other and pick up the product to be tested placed on it. Subsequently, the lifting motor 32 drives the No. 1 insertion / removal fork 301 to rise to the running height 322 again, and maintains this height while moving to the insertion / removal station 34 under the drive of the slide table I. The lifting motor 32 drives the No. 1 insertion / removal fork 301 to descend to the insertion / removal height 323. After the descent is completed, the product to be tested placed on it is manually connected to the current collector box 330 fixed on the No. 1 insertion / removal fork 301 (i.e., wired). The current collector box 330 continuously supplies power to the product to be tested, so that the product remains on the screen during the AOI inspection process.

[0042] After the wire insertion is completed, the lifting motor 32 drives the No. 1 insertion fork 301 to rise to the operating height 322 and moves to the AOI inspection mechanism 4 under the drive of the slide table I. Then, the lifting motor 32 drives the No. 1 insertion fork 301 to descend to the interlocking height 321 to complete the interlocking of the No. 1 insertion fork 301 with the fixed fork 41. After the fixed fork 41 picks up the product to be tested, the lifting motor 32 drives the No. 1 insertion fork 301 to descend again by 10~20mm to prevent the No. 1 insertion fork 301 from affecting the subsequent inspection effect, and maintains this height until the product to be tested completes the AOI inspection.

[0043] In this embodiment, the AOI inspection mechanism 4 includes a fixed fork 41 and an AOI optical component 42 for product inspection disposed above it. The fixed fork 41 is provided with a fixed fork suction cup 412 for adsorbing products and a sensor 411 for sensing products. Specifically, as Figure 12 As shown, the fixed tooth fork 41 includes five fixed forks 410, which are arranged equidistantly in parallel, and the width of each fixed fork 410 is wider than the width of the insertion / removal fork 332. In this embodiment, four fixed tooth fork suction cups 412 are provided on each of the three middle fixed forks 410, and the four fixed tooth fork suction cups 412 are arranged in a square; a sensor 411 for sensing whether there is a product to be tested on the fixed tooth fork 41 is provided on the middle fixed fork 410. Of course, in other embodiments, the number and position distribution of the fixed tooth fork suction cups 412 can be set according to requirements, and are not limited here.

[0044] The AOI optical component 42 also includes a mechanism mounting frame and an AOI optomechanical component. The AOI optomechanical component and the fixed tooth fork are installed sequentially from top to bottom on the mechanism mounting frame. When the fixed tooth fork 41 picks up the product, the AOI optomechanical component performs AOI inspection on the product to be tested.

[0045] After the product inspection is completed, the lifting motor 32 drives the No. 1 insertion and extraction tooth fork 301 to rise to the grasping height 321 to pick up the product and transfer the product to the No. 1 insertion and extraction tooth fork 301. After that, the lifting motor 32 drives the No. 1 insertion and extraction tooth fork 301 to rise to the running height 322 and move to the insertion and extraction station 34 under the drive of the slide table I. Then, the lifting motor 32 drives the No. 1 insertion and extraction tooth fork 301 to descend to the insertion and extraction height 323. After the descent is completed, the product to be tested placed on it is disconnected from the current collector box 330 fixed on the No. 1 insertion and extraction tooth fork 301 (i.e., wire disconnection).

[0046] After the wire pulling is completed, the lifting motor 32 drives the No. 1 insertion and extraction tooth fork 301 to rise to the operating height 322 and move to the unloading handover position under the drive of the slide table I. Then, the lifting motor 32 drives the No. 1 insertion and extraction tooth fork 301 to fall to the hand-holding height 321. At the same time, the second receiving tooth fork 202 moves to the unloading handover position under the drive of the linear motor 205, completing the hand-holding of the No. 1 insertion and extraction tooth fork 301 and the second receiving tooth fork 202. The second receiving tooth fork 202 picks up the product through the receiving suction cup 22 set on it. After that, the second receiving tooth fork 202 moves to the unloading machine 5 under the drive of the linear motor 205.

[0047] In this embodiment, the unloading mechanism 5 includes a lifting and discharging fork conveying mechanism, on which a lifting and discharging fork, an NG material discharging station, and an OK material discharging station are provided. The NG material discharging station and the OK material discharging station are located at different heights at the same position and are downstream of the lifting and discharging fork, receiving NG material or OK material from the lifting and discharging fork. When the second receiving fork 202 moves to the unloading mechanism 5, the second receiving fork 202 interacts with the lifting and discharging fork, transferring the inspected product from the second receiving fork 202 to the lifting and discharging fork. The lifting and discharging fork then discharges the inspected product to the NG material discharging station or the OK material discharging station according to the product inspection result.

[0048] In this embodiment, as shown in the figure, two AOI detection mechanisms 4 and two insertion / removal mechanisms 3 are provided. The two AOI detection mechanisms 4 are arranged side by side between the loading mechanism 1 and the unloading mechanism 5, and the two insertion / removal mechanisms 3 are arranged side by side in front of the AOI detection mechanisms 4. Each AOI detection mechanism 4 corresponds to one insertion / removal mechanism 3. Of course, in other embodiments, the number of insertion / removal mechanisms 3 and AOI detection mechanisms 4 can be set according to requirements, such as three or four, etc., and is not limited here. Specifically, AOI detection mechanism I and AOI detection mechanism II are arranged side by side between the loading mechanism 1 and the unloading mechanism 5. Insertion / removal mechanism I is arranged in front of AOI detection mechanism I, and insertion / removal mechanism II is arranged in front of AOI detection mechanism II. When the No. 1 insertion / removal tooth fork 301 in insertion / removal mechanism I receives the product to be tested from the first receiving tooth fork 201, during the process of insertion, AOI detection, and removal of the product to be tested driven by the No. 1 insertion / removal tooth fork 301, after receiving another product to be tested from the feeding mechanism 1, the first receiving tooth fork 201 moves horizontally to the insertion / removal junction of insertion / removal mechanism II under the drive of the linear motor 205. The No. 3 insertion / removal tooth fork 303 on insertion / removal mechanism II grasps the first receiving tooth fork 201, and picks up the product to be tested. The No. 3 insertion / removal tooth fork 303 drives the product to move, completing the insertion, AOI detection, and removal of the product to be tested. This process is consistent with the movement process of the No. 1 insertion / removal tooth fork 301 and will not be described again here. Of course, in some embodiments, the running height 322 and insertion / removal height 323 of the No. 3 insertion / removal tooth fork 303 may be different from the No. 1 insertion / removal tooth fork 301, and can be set according to the needs of equipment operation, which is not limited here.

[0049] When both the No. 1 insertion / removal fork 301 of insertion / removal mechanism I and the No. 3 insertion / removal fork 303 of insertion / removal mechanism II are receiving products to be tested, the first receiving fork 201 receives the product to be tested from the feeding mechanism 1 and moves to the insertion / removal junction position of insertion / removal mechanism I under the drive of linear motor 205. The No. 2 insertion / removal fork 302 of insertion / removal mechanism I grasps and picks up the product with the first receiving fork 201, driving the product to be tested to complete the insertion, AOI detection and removal process. After that, the first receiving fork 201 receives the product to be tested and moves to the insertion / removal junction position of insertion / removal mechanism II to transfer the product to the No. 4 insertion / removal fork 304. The movement process of the No. 4 insertion / removal fork 304 is the same as that of the No. 3 insertion / removal fork 303. However, in some embodiments, the running height 322 and insertion / removal height 323 of the No. 4 insertion / removal fork 304 and the No. 3 insertion / removal fork 303 may be different.

[0050] In this embodiment, by setting up two sets of AOI inspection mechanisms 4 and insertion / removal mechanisms 3, when one AOI inspection mechanism 4 is running, the other AOI inspection mechanism 4 can be used to inspect the product under test, realizing the simultaneous inspection of multiple products under test and effectively improving the equipment operating efficiency. At the same time, two insertion / removal toothed forks 33 are set in each insertion / removal mechanism 3. When one insertion / removal toothed fork 33 is waiting for the product to complete the inspection at the AOI inspection mechanism 4, the other insertion / removal toothed fork 33 can be used to pick up the material, so that the insertion of another product under test can be completed while one product is being inspected by AOI. This effectively reduces the waiting time of each mechanism during equipment operation and effectively improves the inspection efficiency.

[0051] In some embodiments, the above-described AOI inspection device can be applied to other panel inspection equipment to improve the operating efficiency of the equipment and increase the panel inspection efficiency.

[0052] Example 2

[0053] Based on the AOI detection device provided in Embodiment 1, this embodiment provides an AOI detection method, including the following steps: S1, the product to be tested is fed into the feeding mechanism 1, the feeding tooth fork 101 in the feeding mechanism 1 drives the product to be tested to move under the drive of the moving component, after the code reader 62 and the alignment component 61 complete the code reading and position correction of the product to be tested, the feeding tooth fork 101 and the first receiving tooth fork 201 are grasped, and the first receiving tooth fork 201 picks up the product to be tested.

[0054] S2, the first receiving fork 201 moves under the drive of the linear motor 205 to transport the product to be tested to the insertion / removal mechanism I. The first receiving fork 201 and the first insertion / removal fork 301 are engaged, and the product to be tested is transferred from the first receiving fork 201 to the first insertion / removal fork 301. S3, the first insertion / removal fork 301 is raised to the operating height 322 under the drive of the lifting motor 32 and moves to the insertion / removal station 34 under the drive of the slide table I. Then, the lifting motor 32 drives the first insertion / removal fork 301 to descend. At insertion height 323, the product to be tested is inserted. After insertion, the No. 1 insertion fork 301, driven by the lifting motor 32, rises again to the running height 322 and moves along the slide table I to the AOI inspection mechanism 4. The No. 1 insertion fork 301, driven by the lifting motor 32, descends again to the grasping height 321 to complete the grasping of the No. 1 insertion fork 301 and the fixed fork 41, transferring the product to be tested onto the fixed fork 41. The AOI optical component 42 is used to complete the inspection of the product to be tested.

[0055] S4. After the inspection is completed, the No. 1 insertion and extraction tooth fork 301, which is waiting below the fixed tooth fork 41, rises under the drive of the lifting motor 32 to pick up the product that has been inspected and placed on the fixed tooth fork 41. Then it rises again to the running height 322 and moves along the slide table I to the insertion and extraction station 34. Under the drive of the lifting motor 32, it descends to the insertion and extraction height 323 to complete the wire extraction. After the wire extraction is completed, the No. 1 insertion and extraction tooth fork 301 rises to the running height 322 under the drive of the lifting motor 32 and moves along the slide table I to the handover position.

[0056] S5, the second receiving fork 202 moves to the handover position and grasps the first insertion fork 301, transferring the inspected product to the second receiving fork 202. Driven by the linear motor 205, the second receiving fork 202 moves the inspected product to the unloading mechanism 5 for unloading.

[0057] While one product is undergoing the above steps, another product can be transported to the insertion / removal mechanism II via the first receiving fork 201. The first receiving fork 201 then interacts with the third insertion / removal fork 303 in the insertion / removal mechanism II to transfer the product to be tested onto the third insertion / removal fork 303. This process is repeated, and the AOI inspection mechanism II completes the inspection of the other product. Simultaneously, the first and second insertion / removal forks 301 and 302 in the insertion / removal mechanism I can alternately transport the product to be tested, improving equipment operating efficiency. Similarly, the third and fourth insertion / removal forks 303 and 304 in the insertion / removal mechanism II can also alternately transport the product to be tested. This method allows for the simultaneous inspection of multiple products using the same equipment, effectively reducing the waiting time of each mechanism and optimizing inspection efficiency.

It should be noted that those skilled in the art can make several improvements and modifications to the present invention without departing from the principle of the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
