[0024] During operation, a material tray containing materials is placed inside the silo structure 20, and the tooling 90 follows the circulation structure 30a to flow to the positioning mechanism 30b, and the positioning mechanism 30b positions the tooling 90. The material picking and placing mechanism 40 drives the material picking structure 50 and the angle adjustment mechanism 60 to move to the silo structure 20, and the material picking structure 50 picks up the materials. The material picking and placing mechanism 40 then drives the material picking structure 50, the angle adjustment mechanism 60 and the picked up materials to move to the visual inspection structure 70, and the visual inspection structure 70 inspects the materials. The visual inspection mechanism 70 inspects the materials. After the information is detected, an electrical signal is sent out. The angle adjustment mechanism 60 adjusts the angle of the material picking structure 50 according to the detection information of the visual detection structure 70, thereby adjusting the angle of the material. The material picking and placing mechanism 40 then places the material after the angle adjustment on the tooling 90 at the positioning mechanism 30b. The tooling 90 and the material follow the flow structure 30a to flow to the assembly station. The material picking and placing and angle adjustment are all completed by the angle-adjustable loading device, which does not require manual participation, can improve the efficiency and accuracy of picking and placing materials, and solves the problem of low efficiency and low accuracy of manual picking and placing of materials.

[0026] In the present invention, the angle adjustment mechanism 60 includes a mounting frame 61 fixed to the output portion of the material picking and placing mechanism 40, a rotation drive mechanism 62 fixed to the mounting frame 61, and the material picking structure 50 is fixed to the output portion of the rotation drive mechanism 62. The rotation drive mechanism 62 drives the material picking structure 50 to rotate, thereby adjusting the direction of the material on the material picking structure 50, such as Figure 2 and Figure 3 As shown, Figure 3 Only the bottom plate portion of the overall structure of the mounting frame 61 is shown, and the rest is omitted.

[0027] Specifically, the material taking structure 50 is a profiling seat, on which a suction nozzle is provided, and the material is adsorbed on the profiling seat by suction. Of course, a clamping claw structure can also be provided on the profiling seat to clamp the material.

[0028] like Figure 2 and Figure 3 As shown, the angle adjustment mechanism 60 also includes a position detection sensor 64 fixed to the mounting frame 61 at a position on the side of the material picking structure 50, and a sensing sheet 63 fixed on the material picking structure 50. The sensing sheet 63 rotates with the material picking structure 50, and the corresponding position of the sensing sheet 63 and the position detection sensor 64 is the initial angle. Angle adjustment is performed based on this, which can improve the adjustment accuracy.

[0029] In order to further improve work efficiency, two groups of material picking structures 50 are arranged on the output part of the material picking and placing mechanism 40, and an angle adjustment mechanism 60 is respectively provided at each group of material picking structures 50. Specifically, the mounting frames 61 of the two groups of angle adjustment mechanisms 60 are connected to form a supporting structure for easy installation.

[0030] Usually, the rotation drive mechanism 62 is a motor, and usually, an axial through hole is provided on the rotating shaft of the motor to facilitate communication with the suction nozzle. Of course, the rotation drive mechanism 62 can also be an electric turntable.

[0031] In the utility model, a height adjustment mechanism is also installed on the output part of the material picking and placing mechanism 40. The material picking structure 50 and the angle adjustment mechanism 60 are installed on the output part of the height adjustment mechanism. When the material picking structure 50 needs to pick and place materials and the visual inspection mechanism 70 performs visual inspection on the materials, the height adjustment mechanism can control the height of the material picking structure 50 and the angle adjustment mechanism 60 to better cooperate with the material picking and placing and visual inspection processes.

[0032] Specifically, the height adjustment mechanism is a cylinder, and of course, it can also be an inductor.

[0033] When two sets of material picking structures 50 and angle adjustment mechanisms 60 are provided on the output part of the material picking and placing mechanism 40, the support structure is fixedly connected to the output part of the height adjustment mechanism, and the support structure is mounted on the output part of the material picking and placing mechanism 40 and slides, so that the height adjustment can be achieved more stably.

[0034] In the utility model, the silo structure 20 includes a storage silo 21, a recovery silo 22 and a tray transfer mechanism 23 arranged between the storage silo 21 and the recovery silo 22; the storage silo 21 includes a storage silo body, a loading lifting drive mechanism arranged inside the storage silo body and a loading pallet fixed on the output part of the loading lifting drive mechanism; the recovery silo 22 includes a recovery silo body, a recovery lifting drive mechanism arranged inside the recovery silo body and an empty tray pallet fixed on the output part of the recovery lifting drive mechanism; the tray transfer mechanism 23 includes a tray translation drive mechanism, a transport lifting drive mechanism fixed on the output part of the tray translation drive mechanism and a transport structure fixed on the output part of the transport lifting drive mechanism.

[0035] During operation, the loading and lifting drive mechanism of the storage bin 21 drives the loading pallet to fall. After placing multiple layers of trays containing materials on the loading pallet, the material picking and placing mechanism 40 drives the material picking structure 50 and the angle adjustment mechanism 60 to move to the storage bin 21 to pick up the materials; after taking the materials on one layer of trays, the tray transfer mechanism 23 picks up the empty trays inside the storage bin 21 and places them on the empty tray pallet inside the recovery bin 22.

[0036] Specifically, the loading lifting drive mechanism, the recovery lifting drive mechanism and the tray translation drive mechanism are electric cylinders, and the transport lifting drive mechanism is an electric cylinder or a pneumatic cylinder.

[0037] In the present invention, the circulation structure 30a is a conveyor belt, which is driven to rotate by a motor.

[0038] Correspondingly, the positioning mechanism 30b includes blocks respectively arranged on opposite sides of the flow structure 30a, and a block translation driving mechanism for driving the block to move above the flow structure 30a or away from the flow structure 30a. Usually, the block translation driving mechanism is a cylinder, and of course, it can also be set as an electric cylinder.

[0039] In the present invention, the material picking and placing mechanism 40 is a four-axis robot.

[0040] In some other embodiments, the material picking and placing mechanism 40 can also be set as the following structure, including a picking and placing bracket fixed on the workbench, a first material translation drive mechanism fixed on the picking and placing bracket and arranged between the storage bin 21 of the bin structure 20 and the circulation structure 30a, a second material translation drive mechanism fixed on the output part of the first material translation drive mechanism and arranged vertically with the first material translation drive mechanism, and a material lifting drive mechanism fixed on the output part of the second material translation drive mechanism, and the material picking structure 50 and the angle adjustment mechanism 60 are installed on the output part of the material lifting drive mechanism. Usually, the first material translation drive mechanism, the second material translation drive mechanism, and the material lifting drive mechanism are electric cylinders.

[0041] In the present invention, the visual detection structure 70 includes a CCD camera and a light source. Specifically, the visual detection structure 70 is a well-known technology, and its specific structure is not repeated here.

[0042] In the present invention, the angle-adjustable feeding device further includes a buffer structure 80 disposed on the workbench.

[0043] Specifically, the cache structure 80 includes a base, and a material containing cavity is provided on the base.

[0044] When picking up materials, the material picking and placing mechanism 40 drives the picking structure 50, the angle adjustment mechanism 60 and the picked up materials to move to the visual detection structure 70. The visual detection structure 70 not only detects the position information of the material, but also detects the appearance of the material. When there are defects in the appearance of the material, the material picking and placing mechanism 40 drives the picking structure 50, the angle adjustment mechanism 60 and the picked up materials to move to the waste discharge structure for waste discharge. In order to avoid affecting the efficiency, the material picking and placing mechanism 40 drives the picking structure 50 and the angle adjustment mechanism 60 to move to the cache structure 80 to pick up materials for replenishment. When the angle-adjustable feeding device is in a pause interval, the material picking and placing mechanism 40 drives the picking structure 50 to replenish the cache structure 80.

[0045] Specifically, the buffer structure 80 is disposed at a side of the visual detection structure 70 .

[0046] Usually, two material containing cavities are provided on the base, which can hold two materials. Of course, other numbers can also be set according to actual needs.

[0047] The above descriptions are only some embodiments of the present invention and are not intended to limit the present invention.
