As a key component of many electronic products, the quality and performance of 48PIN transformers are directly related to the quality of terminal products. For precision 48PIN transformers, traditional manual inspection methods are difficult to meet the current stringent requirements for inspection accuracy and reliability. Manual inspection is not only inefficient and difficult to keep up with the pace of large-scale production, but also prone to problems such as missed inspections and false inspections due to human factors, increasing the risk of defective products flowing into subsequent production links, thereby raising production costs and after-sales risks.

[0074] A detection method for 48PIN transformer AOI visual inspection equipment, the detection method comprising the following steps:

[0075] S1. Place the material tray equipped with a 48PIN transformer on the material tray upper and lower mechanism 101, start the transfer mechanism 102, the servo motor 17 drives the screw module 18, drives the screw module 2 19 to move horizontally, so that the suction fixture 25 is aligned with the product position, the servo motor 2 191 drives the screw module 2 19 to move longitudinally, adjust the height of the material picking component, the suction magnet telescopic cylinder 23 moves, drives the suction fixture 25 to adsorb the product, and completes the material picking;

[0076] S2, material distribution operation, the transfer mechanism 102 sends the 48PIN transformer to the material distribution mechanism 103, starts the speed regulating motor 31, cooperates with the synchronous wheel 34 to drive the flat belt 30 to run, and the limiting side plates 301 on both sides of the flat belt 30 limit the transformer. When the transformer is transported to the material distribution clamping plate 302, the material distribution cylinder 1 32 pushes the material distribution clamping plate 302 to clamp the transformer to achieve material distribution;

[0077] S3, the 48PIN transformer after material distribution is sent into the guide groove 43 by the cam mechanism 104. When the transformer blocks the signal of the optical fiber assembly 411, the material distribution cylinder 2 36 pushes the push block 42 to push the transformer to the feeding mechanism 105;

[0078] S4, the feeding mechanism 105 starts the servo motor 3 44, drives the X-direction moving cam 48 and the Y-direction moving cam 49 to rotate, and the cam drives the related components to make the fork block 54 move in a specific direction, and push the 48PIN transformer to the AOI visual inspection mechanism 106 inspection area for inspection;

[0079] S5. The 48PIN transformer that has been tested enters the unloading mechanism 107. Depending on whether the product is good or defective, the material separation moving cylinder body 71 and the lifting cylinder 72 work together to send the good and defective products into the feeding track body 60 and the material pipe on the left and right sides respectively. When the material pipe is full, the material pipe is pushed to the storage box through the external pushing mechanism.

[0080] Working principle:

[0081] The first step is to place the tray with the 48PIN transformer on the tray upper and lower mechanism 101, and cooperate with the transfer mechanism 102 to transfer the 48PIN transformer;

[0082] When the transfer mechanism 102 is working, the servo motor 17 is started to provide the driving force of the screw module 18, and the screw module 18 is used to drive the screw module 2 19 to move horizontally to change the lateral position of the suction fixture 25, so that the suction fixture 25 moves to the position where the product is located or the position where the product needs to be placed. Then, the servo motor 2 191 is started to increase the driving force of the screw module 2 19, and the screw module 2 19 is used to drive the module connecting plate 20 to move longitudinally to lower or increase the position of the material picking component. After that, the position of the material picking component is lowered to the appropriate position of the product by using the screw module 2 19, and the suction magnet telescopic cylinder 23 is started to push down the cylinder connecting block 24 and the suction magnet body 26 to drive the suction fixture 25 to move down close to the product or move up away from the product, and the suction fixture 25 cooperates with the suction magnet body 26 to absorb or release the product to perform the product picking or product placement operation;

[0083] Use magnetic suction to clamp the transformer:

[0084] 1. Unlike the traditional clamping method, the magnetic suction method will not exert pressure on the transformer that may cause damage. Since the transformer is adsorbed by magnetic force, it avoids problems such as deformation of the transformer shell, damage to the internal winding or bending of the pins due to excessive clamping pressure. For products with relatively delicate structures such as 48PIN transformers, it can effectively protect the integrity and performance of the product;

[0085] Second, the magnetic suction method has better adaptability when facing transformers of different shapes and sizes. No matter the transformer is a regular rectangular parallelepiped or has a special shape, as long as it contains magnetizable materials, the suction fixture 25 can be adsorbed by magnetic force;

[0086] When the material suction magnet body 26 moves downward, it will drive the guide shaft 28 to slide up and down inside the linear bearing 27. The linear bearing 27 and the guide shaft 28 can guide the movement of the material suction magnet body 26, thereby improving the stability of the material suction magnet body 26 moving downward or upward.

[0087] In the second step, the transfer mechanism 102 is used to transfer the 48PIN transformer to the material distribution mechanism 103 for material distribution. When the material distribution mechanism 103 is working, the speed regulating motor 31 is started, and the synchronous wheel 34 is cooperated to provide the driving force of the flat belt 30 and the turning track 35, and the 48PIN transformer is placed on the top of the flat belt 30. The 48PIN transformer is transported by the flat belt 30. The limiting side plates 301 on both sides of the top of the flat belt 30 limit the transported 48PIN transformer to prevent the 48PIN transformer from falling from the flat belt 30, thereby ensuring the stability of the transformer during transportation;

[0088] When the 48PIN transformer is transported between the material dividing clamping plates 302, the material dividing cylinder 1 32 is used to push the material dividing clamping plates 302 to clamp the 48PIN transformer, blocking the transformer to be transported subsequently. The transformer that is not clamped is transported by the flat belt 30 to the flip track 35 for further transportation. After a certain distance from the clamped transformer, the material dividing cylinder 1 32 drives the material dividing clamping plates 302 to retreat and stop clamping the transformer. Repeat the above operation to process multiple transformers.

[0089] The side wall corresponding to the feed inclined block 303 is a bevel, and the bevel side wall of the feed inclined block 303 can guide the transformer being transported, so that the transformer can be accurately transported between the material dividing clamping plates 302;

[0090] The tensioning wheel 33 is used to adjust the tension of the flat belt 30 to ensure that the flat belt 30 does not slip or deviate due to being too loose or too tight during operation, thereby ensuring stable operation and transmission efficiency of the flat belt 30 .

[0091] In the third step, the 48PIN transformer that has been divided by the dividing mechanism 103 is sent to the feeding mechanism 105 by the cam mechanism 104. When the cam mechanism 104 is working, the 48PIN transformer enters the guide groove 43 from the feeding groove 431, and the 48PIN transformer enters the guide groove 43 along the front end wall of the pusher block 42. When the right side of the 48PIN transformer collides with the inner right wall of the guide groove 43, the 48PIN transformer blocks the signal of the opposite-shooting optical fiber component 411. The insertion of the 48PIN transformer is detected by the opposite-shooting optical fiber component 411, and the dividing cylinder 2 36 is started to push the pusher block 42.

[0092] When the pushing block 42 is pushed and moved by the material distribution cylinder 2 36 , it will push the 48PIN transformer in the guide groove 43 to move, thereby pushing the 48PIN transformer to the required position for loading work.

[0093] In the fourth step, the 48PIN transformer is fed into the feeding mechanism 105 by the cam mechanism 104, and the feeding mechanism 105 pushes the 48PIN transformer to the position of the AOI visual inspection mechanism 106 for visual inspection;

[0094] When the feeding mechanism 105 is working, the servo motor 3 44 is started to drive the X-direction moving cam 48 and the Y-direction moving cam 49 to rotate. The Y-direction moving cam 49 first contacts the rear end of the cam rod 51, pushes the rear end of the cam rod 51 to tilt it, and the front end of the cam rod 51 drives the Y-axis cam follower 53 to push the Y-direction moving plate 521 to drive the fork block 54 to move toward the position of the inverter in the trough body 541. The slider at the bottom of the Y-direction moving plate 521 follows it to move on the Y-direction moving guide rail 52. When the groove of the fork block 54 is stuck on the outside of the inverter, the slider at the bottom of the Y-direction moving plate 521 is locked, so that the fork block 54 remains inserted in the position outside the inverter. At this time, the moving direction of the fork block 54 toward the inverter is the +y direction. Figure 4 As indicated by the arrow in the middle;

[0095] Afterwards, the X-direction moving cam 48 rotates and pushes the X-axis cam follower 50 to move the X-direction moving plate 551 connected by the push rod 501 forward, and the slider at the bottom of the X-direction moving plate 551 follows it to move on the X-axis direction moving guide rail 55. When the X-direction moving cam 48 stops pushing the X-axis cam follower 50, the slider at the bottom of the X-direction moving plate 551 is locked, so that the position of the X-direction moving plate 551 is fixed, and the movement of the X-direction moving plate 551 drives the fork block 54 to move forward, thereby pushing the inverter in the groove of the fork block 54 forward. At this time, the moving direction of the fork block 54 is the +x direction, such as Figure 4 As indicated by the arrow in the middle;

[0096] Then, the slider at the bottom of the Y-direction moving plate 521 cooperates with the Y-direction moving guide rail 52 to drive the Y-direction moving plate 521 and the fork block 54 to move toward a position away from the inverter, and the moving direction is the -y direction. Figure 4 As indicated by the logo;

[0097] After the fork block 54 is away from the inverter, the slider at the bottom of the X-direction moving plate 551 cooperates with the X-axis moving guide rail 55 to drive the Y-direction moving plate 521 and the fork block 54 to move backward and reset, and the moving direction is the -x direction. Figure 4 As indicated by the logo;

[0098] Repeat the above operation, the moving direction of the fork block 54 is first moving in the +y direction to approach the inverter, then moving in the +x direction to push the inverter to move, then moving in the -y direction to retreat away from the inverter, and finally moving in the -x direction to reset and push the next group of inverters. Repeat this cycle in sequence, and the fork block 54 can move back and forth to transport the inverter.

[0099] When the 48PIN transformer is sent to the detection area of ​​the AOI visual inspection mechanism 106 by the feeding mechanism 105, the camera body 121 and the lens 9 are used to detect the 48PIN transformer, and the detection data is transmitted to the terminal device. At the same time, the light source body 12 can be used to perform fill light operation on the camera body 121 to ensure the detection effect of the 48PIN transformer;

[0100] The profile side panel 3 and the angle adjustment plate 8 are used to adjust the detection angle of the lens 9. The hand wheel 10 drives the screw of the screw slide body 11 to rotate and drive the slide to move to adjust the distance of the light source body 12 to ensure that it can be in the most suitable position for the lens 9, thereby performing fill light.

[0101] In the fifth step, the 48PIN transformers inspected by the AOI visual inspection mechanism 106 are transported by the unloading mechanism 107, and good products and bad products are separated. When the unloading mechanism 107 is working, the whole device is tilted, and the left feeding track body 60 is set as the good product conveying area, and the right feeding track body 60 is set as the bad product conveying area. The clamping cylinder 57 pushes the material tube limit block 56 to clamp on the side wall of the material tube to limit the material tube. It should be noted that the material tube can store 48PIN transformers so that they are arranged in the material tube, and a storage box is provided at the bottom of the material tube;

[0102] When the incoming 48PIN transformer is good, the material distribution moving cylinder body 71 pushes the material distribution moving block 68 to move to the material inlet position at the rear end of the incoming track 66, and the material blocking floating mechanism 70 moves with the material distribution moving block 68. Subsequently, the good 48PIN transformer is sent into the material distribution moving block 68 and blocked by the material blocking floating mechanism 70. After that, the lifting cylinder 72 pushes up the floating lifting block 69 to drive the material blocking floating mechanism 70 to move out of the material distribution moving block 68. The 48PIN transformer that loses the blocking of the floating lifting block 69 enters the left feeding track body 60, and the 48PIN transformer enters the left material pipe for storage.

[0103] When the incoming 48PIN transformer is defective, the material dividing moving cylinder body 71 first pushes the material dividing moving block 68 to move to the material inlet position at the rear end of the incoming track 66, and the material stopping floating mechanism 70 moves with the material dividing moving block 68. Subsequently, the good 48PIN transformer is sent into the material dividing moving block 68 and is stopped by the material stopping floating mechanism 70. After that, the material dividing moving cylinder body 71 drives the material dividing moving block 68 to move to the position of the right side feeding track body 60 of defective products. Finally, the lifting cylinder 72 pushes up the floating lifting block 69 to drive the material stopping floating mechanism 70 to move out of the material dividing moving block 68. The 48PIN transformer that loses the stopping of the floating lifting block 69 enters the right side feeding track body 60, and the 48PIN transformer enters the right side material pipe for storage.

[0104] A 48PIN transformer is fed in by the incoming material track 66. After the incoming material arrival detection optical fiber 65 detects the 48PIN transformer, the incoming material dividing cylinder body 67 is started to block the subsequent 48PIN transformer. When the incoming 48PIN transformer is divided, the 48PIN transformer is fed into the position of the feed track body 60 and detected by the product arrival optical fiber 62. In cooperation with the incoming material dividing cylinder body 67, the subsequent 48PIN transformer is stopped to allow the next 48PIN transformer to be fed in for dividing.

[0105] When a sufficient number of 48PIN transformers are stored in the material tube, the tube clamping cylinder 57 is first used to drive the material tube limit block 56 to move away from the side wall of the material tube to stop the tight fixation of the material tube. At the same time, the material tube is in place and the tightening cylinder 75 loses the tight fixation on the rear end of the material tube. Afterwards, the push-tube moving plate 74 is pushed by the outward pushing mechanism at the bottom of the push-tube moving plate 74 to move the material tube outward, and the material tube is moved to the storage box at the bottom of the equipment. Since the equipment is tilted, at this time, the 48PIN transformer stored in the material tube slides into the storage box at the bottom of the equipment.
