The first linear module 41 is connected to a second linear module 42, and the second linear module 42 is drivenly connected to the conveying gripper 5. The first linear module 41 and the second linear module 42 are arranged perpendicularly to each other, forming a two-axis motion module, which can easily drive the conveying gripper 5 to move in space, resulting in high conveying efficiency and accurate material picking position.

The support surface 77 is provided with a limiting pin 78 that matches the tray 3, which can prevent the tray 3 from shaking and causing planar displacement, thus ensuring the transfer accuracy of the tray 3.

[0048] In one embodiment of this utility model, the positioning component 8 includes a positioning frame 81, with clamping components 82 on both sides of the positioning frame 81, and material blocking components 83 on both sides of the clamping components 82.

[0049] Specifically, the clamping cylinder 821 drives the clamping block 822 to clamp the two sides of the support plate 75. The support plate supports the material tray 3 and the stop rod 831 positions the edge of the material tray 3, quickly completing the positioning of the material tray 3, facilitating accurate loading of the product into the material tray 3 and reducing the difficulty of loading the product.

[0050] In one embodiment of this utility model, the material blocking component 83 includes a material blocking rod 831, and material blocking cylinders 832 are provided on both sides of the positioning frame 81.

The material blocking cylinders 832 drive the material blocking groove 833 on the material blocking rod 831 to position the material tray 3.

[0051] Specifically, the lifting cylinder 73 drives the support tray and material tray 3 on the vacuum tray to rise, so that the edge of the material tray 3 is clamped on the material blocking groove 833, so that the material blocking groove 833 is aligned with the material tray 3 for material blocking and positioning, which can effectively prevent the material tray 3 from shaking. At the same time, the material blocking cylinder 832 drives the material blocking rod 831 to move, thereby adjusting the minimum distance between the two material blocking rods 831 to adapt to clamping and positioning material trays 3 of different sizes.

[0052] Usage process

[0053] The product-loaded trays 3 are stacked one by one on the loading rack 11. The bottom of the trays 3 is supported by the support plate 12. The guide grooves 15 on the loading plate 14 support and guide the four corners of the stacked trays 3, allowing the trays 3 to be accurately lifted to the loading position along the guide grooves 15. The lifting linear module 22 drives the lifting plate 24 on the lifting frame 21 to move upward, so that the lifting plate 24 passes through the hollow part 13 and abuts against the stacked trays 3. Under the action of the lifting linear module 22, the trays 3 are lifted to the loading position. The entire stacked tray 3 is lifted, so that the top tray 3 is lifted to the loading position, ensuring the efficiency of loading the tray 3 and facilitating subsequent handling operations. The first linear module 41 and the second linear module 42 are vertically arranged to form a two-axis motion module. The two-axis motion module drives the handling gripper 5 to move to the loading position. The barcode scanner 54 on the test frame scans and records the barcode on the tray 3. Then, the spring suction cup 53 on the handling plate 52 picks up the surface of the tray 3. The two-axis motion module... The assembly then moves the material tray 3, gripped by the handling gripper 5, to the limiting mechanism 6. The two-axis motion module then moves the material tray 3 onto the support plate 75 on the transfer assembly 7. The limiting cylinders 62 on both sides of the limiting frame 61 drive the limiting push blocks 63 to center and position the material tray 3 on the transfer assembly 7. The transfer linear module 71 then drives the support tray and the material tray 3 on the vacuum tray to move to the positioning assembly 8. The blocking cylinder 832 aligns the blocking groove 833 on the blocking rod 831 with the edge of the material tray 3. The lifting cylinder 73 drives the support tray and material tray 3 on the vacuum tray to rise, so that the edge of the material tray 3 is clamped on the material stop groove 833, so that the material stop groove 833 is aligned with the material tray 3 for material stop positioning. At the same time, the clamping cylinder 821 drives the clamping block 822 to clamp the two sides of the support plate 75. Through the support tray supporting the material tray 3 and the material stop rod 831 positioning the edge of the material tray 3, the positioning of the material tray 3 is quickly completed, which facilitates the accurate loading of the product into the material tray 3 and reduces the difficulty of loading the product.
