After the positioning component 4 centers and positions the tray 17 at the positioning station, the lifting component 7 drives the conveying track 1 to move so that the tray 17 on it is dropped onto the fixture component 5 for adsorption and positioning. This completes the positioning of the tray 17 and each product in the tray 17, ensuring the efficiency of online product inspection and greatly improving the accuracy of visual inspection. The blocking component 3 is used to block and limit the tray 17 at the positioning station, which can ensure the relative positional accuracy of the tray 17 and the fixture component 5, improve the positional accuracy of the tray 17 on the fixture component 5, and improve the accuracy of subsequent processing.

The material blocking cylinder 32 is drivenly connected to a material blocking bracket 33, and a material blocking rod 34 is provided on the material blocking bracket 33. The material blocking cylinder 32 drives the material blocking rod 34 to pass through the conveying track 1 to block and limit the material tray 17 at the positioning station. This can ensure the relative positional accuracy of the material tray 17 and the fixture component 5, improve the positional accuracy of the material tray 17 on the fixture component 5, and improve the subsequent processing accuracy.

The adsorption elements 6 are arranged one-to-one with the placement slots 63 on the material tray 17. The vacuum suction plate generates negative pressure on the adsorption elements 6, so that the adsorption elements 6 are used to adsorb and position the products in the placement slots 63, quickly positioning the products and the material tray 17, and ensuring detection accuracy.

[0042] In one embodiment of this utility model, the adsorption member 6 includes a plurality of adsorption blocks 61, which are arranged to form an adsorption station. The adsorption blocks 61 are provided with adsorption holes 62, which are connected to the vacuum suction plate. The storage tank 63 is provided with a through groove 64 that matches the adsorption blocks 61. The adsorption blocks 61 pass through the through groove 64 to pick up the product on the storage tank 63.

[0043] Specifically, the suction valve 55 and the control valve 54 are connected to the vacuum generator, which causes the suction holes 62 on the suction block 61 to generate negative pressure, thereby sucking up the products on the storage tank 63. This completes the positioning of the tray 17 and each product in the tray 17, improving the efficiency of online product detection.

[0044] In one embodiment of this utility model, the vacuum suction plate includes a mounting frame 51, an adapter plate 52 is provided on the mounting frame 51, a plurality of suction holes 53 are provided on the adapter plate 52, a control valve 54 is provided on the suction holes 53, a suction channel is provided inside the mounting frame 51, the suction channel is connected to the suction holes 53 on the adapter plate 52, a suction valve 55 is provided on the suction channel, a reference plate 56 is provided on the adapter plate 52, a guide hole 57 is provided on the reference plate 56, one end of the guide hole 57 is connected to the suction hole 53, and the other end is connected to the adsorption hole 62.

[0045] Specifically, the suction valve 55 and the control valve 54 are connected to the vacuum generator, and the suction channel, suction hole 53 and adsorption hole 62 are connected to each other, so that the adsorption hole 62 on the adsorption block 61 generates negative pressure, which picks up the product on the placement slot 63. Each adsorption element 6 adopts an independent vacuuming method, which can ensure the stability of product pick-up, avoid product position shaking during the monitoring process, and improve detection accuracy.

[0046] In one embodiment of the present invention, the positioning component 4 includes a positioning frame 41, a pusher frame 42 is slidably mounted on the positioning frame 41, a pusher rod 44 is slidably mounted on the pusher frame 42, a buffer is provided between the pusher rod 44 and the pusher frame 42, a pusher block 45 is provided at the free end of the pusher rod 44, and a positioning cylinder 43 is provided on the positioning frame 41, and the positioning cylinder 43 is drivenly connected to the pusher frame 42.

[0047] Specifically, the positioning cylinder 43 drives the pusher block 45 on the pusher rod 44 to abut against the side of the material tray 17. The pusher block 45 is a rotating wheel. The positioning components 4 on both sides push the material tray 17 on the conveying track 1 synchronously to center and position the material tray 17, ensuring the relative position accuracy between the material tray 17 and the fixture plate 58.

[0048] In one embodiment of this utility model, the buffer includes a buffer frame 46, which is disposed on the pusher frame 42. A spring 47 is disposed on the pusher rod 44, and the free end of the spring 47 is connected to the buffer frame 46. A limit frame 48 is disposed on the pusher rod 44, and a limit block 49 matching the limit frame 48 is disposed on the pusher frame 42. Under the action of the spring 47, the limit frame 48 abuts against the limit block 49. A detection piece 491 is disposed on the pusher frame 42, and a slotted photoelectric switch 492 matching the detection piece 491 is disposed on the positioning frame 41.

[0049] Specifically, under the reaction of the spring 47, the limiting frame 48 abuts against the limiting block 49, thereby limiting the position of the push rod 44 and preventing it from coming off. When the positioning cylinder 43 drives the push block 45 on the push rod 44 to push and position the material tray 17, if the material tray 17 experiences positional deviation, the spring 47 can be compressed to make the push rod 44 abut against the buffer frame 46, thus preventing damage to the material tray 17 while providing a certain buffer force to ensure the clamping and positioning effect of the material tray 17. The positioning frame 41 is equipped with a slotted photoelectric switch 492 that matches the detection piece 491. By detecting the position of the detection piece 491 through the slotted photoelectric switch 492, the relative position of the push frame 42 and the positioning frame 41 can be detected in real time, preventing excessive force on the push rod 44 from causing equipment damage and ensuring the stability of the push positioning.

[0050] Usage process

[0051] A tray 17 loaded with products is placed on the conveyor track 1. A blocking cylinder 32 drives a blocking rod 34 to pass through the conveyor track 1 to limit the material on the tray 17. The conveyor motor 14 synchronously drives the belt conveyor 12 to transport the tray 17 to the positioning station. Simultaneously, the front end of the tray 17 abuts against the blocking rod 34. Positioning components 4 on both sides synchronously push the tray 17 on the conveyor track 1 to center and position it, ensuring that the tray 17 is directly above the fixture plate 58. The lifting components... 7 drives the conveying track 1 to move downward, causing the material tray 17 on the conveying track 1 to fall onto the fixture component 5. The adsorption block 61 passes through the through groove 64 and abuts against the product on the placement slot 63. The suction valve 55 and the control valve 54 are connected to the vacuum generator, so that the adsorption hole 62 on the adsorption block 61 generates negative pressure, which sucks up the product on the placement slot 63. This completes the positioning of the material tray 17 and each product in the material tray 17, ensuring the efficiency of online product inspection and greatly improving the accuracy of visual inspection.
