Further, referring to fig. 11 and 12, the handling mechanism 400 includes a traversing module 410, a lifting module 420, and at least one pick-and-place member 430. The traversing module 410 is a linear module adapted to move along the width direction of the first rail structure 110 and/or the second rail structure 310. The lifting module 420 is a linear module, and is suitable for moving along the vertical direction, and the lifting module 420 is in transmission connection with the traversing module 410 so as to move under the driving of the traversing module 410. The pick-and-place member 430 is specifically a suction nozzle structure, and is used for picking and placing materials, and the pick-and-place member 430 is in transmission connection with the lifting module 420. Indeed, in other embodiments, the handling mechanism 400 may be provided with other traversing structures, such that the pick-and-place member 430 may also be capable of moving along the length of the first rail structure 110 and/or the second rail structure 310.

Preferably, in order to improve the handling efficiency, the picking and placing members 430 are arranged at intervals along the length direction of the first rail structure 110 and/or the second rail structure 310, and the lifting modules 420 are plural and correspond to the picking and placing members 430 one by one, so that each picking and placing member 430 can lift independently and pick and place materials.

Because the tray 200 is provided with a plurality of placement grooves along the length direction and the width direction of the first guide rail structure 110 and/or the second guide rail structure 310, the material is not placed in place in the process of carrying, which results in that the material is not completely placed in the placement grooves, so that the placement reliability is poor, and the subsequent stacking is affected.

Preferably, the handling mechanism 400 further includes a camera assembly 440 drivingly connected to the traverse module 410, and the camera assembly 440 is adapted to photograph the tray 200 to obtain the material condition in the tray 200.

Referring to fig. 2, 9 and 10, the first rail structure 110 is provided with a beating assembly 170 at the first carrying station 100c, the second rail structure 310 is also provided with a beating assembly 170 at the second carrying station 300b, when the tray 200 is fully loaded with qualified or unqualified products, the camera assembly 440 is adapted to shoot the tray 200 to determine whether the material in the tray 200 is put in place, and when the material is not put in place, the beating assembly 170 is adapted to beat the tray 200 to vibrate the material to make it completely put in the placing groove.

The beating assembly 170 includes a beating cylinder 171 fixedly connected with the rail structure and a beating block 172 drivingly connected with the beating cylinder 171, the beating cylinder 171 being a linear cylinder which can drive the beating block 172 to move along the width direction of the first rail structure 110 and/or the second rail structure 310 and beat the tray 200. Preferably, in order to improve the vibration effect, at least two beating assemblies 170 are disposed on each of the first and second rail structures 110 and 310, and the two beating assemblies 170 are disposed opposite to each other in the width direction of the first and/or second rail structures 110 and 310 to match the beating tray 200.

Further, referring to fig. 1,2, 10 and 13, the first stacking mechanism 500 and the second stacking mechanism 600 have the same structure, and the first stacking mechanism 500 is exemplified as the first stacking mechanism 500, and the first stacking mechanism 500 includes a stacking frame 510, a supporting member 520 and a jacking assembly 530. Openings are provided at the top and bottom of the stacking frame 510, and the tray 200 can be stacked and accommodated in the stacking frame 510 from the bottom of the stacking frame 510 or taken out from the top of the stacking frame 510. The number of the supporting members 520 is plural, and the supporting members 520 are respectively disposed on two sides of the stacking frame 510 in the width direction of the first rail structure 110, and the supporting members 520 on two sides are adapted to cooperate to carry the tray 200. The supporting member 520 is rotatably connected with the stacking frame 510, so as to turn upwards and avoid the tray 200 during the process of stacking the tray 200 into the stacking frame 510, and when stacking is completed, the supporting member 520 is suitable for turning downwards under the action of gravity and carrying the stacked tray 200.

The jacking assembly 530 is located right below the stacking frame 510, and the jacking assembly 530 includes a jacking module 531 and a jacking member 532 in transmission connection with the jacking module 531, where the jacking member 532 can lift the tray 200 upwards into the stacking frame 510 under the driving of the jacking module 531. The jacking module 531 is a linear module, and the disclosure is not described herein.

The number of the lifting members 532 is two, and the two lifting members 532 are oppositely arranged in the width direction of the first rail structure 110, the two lifting members 532 are matched with the lifting tray 200, and the first conveying table 120 can move between the two lifting members 532 to be located right below the tray 200.

the first conveying platform 120 moves to enable the first conveying platform 120 at the front end to move to the second loading station 100b and clamp the empty material tray 200, then the first conveying platform 120 continues to move to enable the first conveying platform 120 at the rear end to be positioned at the first loading station 100a and clamp the material-filled material tray 200, and the first conveying platform 120 at the front end is positioned at the first carrying station 100c; meanwhile, one of the second conveying tables 320 moves to the third loading station 300a to clamp the tray 200 filled with the material and drive it to move to the second carrying station 300b;

Since most of the materials in the tray 200 fully loaded with the detected materials are qualified products, in general, the conveying mechanism 400 conveys the unqualified materials in the tray 200 of the second conveying station 300b to the tray 200 of the first conveying station 100c, after the conveying is completed, the first conveying table 120 at the rear end moves to the first conveying station 100c, the conveying mechanism 400 conveys the qualified materials in the tray 200 of the first conveying station 100c to the tray 200 of the second conveying station 300b, when the tray 200 of the second conveying station 300b is fully loaded with the qualified products, the second conveying table 320 drives the tray 200 to move to the second discharging station 300c to perform discharging, in this process, the other second conveying table 320 continues to move to the third feeding station 300a to receive a new tray 200 fully loaded with materials, and when the tray 200 fully loaded with the qualified products moves to the second discharging station 300c, the new tray 200 fully loaded with the materials moves to the second conveying station 300b so as to perform continuous conveying operation between the first conveying mechanism 400 b and the second conveying station 300 c; when the tray 200 of the first carrying station 100c is fully loaded with the reject, the first conveying table 120 at the rear end moves to the first blanking station 100d to perform blanking on the tray 200, after the blanking is completed, the first conveying table 120 at the rear end moves to the first loading station 100a, and at the same time, the first conveying table 120 at the front end is positioned at the first carrying station 100c so as to continue carrying operation; the steps are repeated, so that materials can be continuously transported, and the transportation efficiency is effectively improved.
