[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0024] like Figure 1 and Figure 2 and Figure 3As shown, the automatic stacking and conveying system includes a frame 1 and a material frame 2, wherein the frame 1 has a conveying portion for conveying the material frame, and the material frame 2 is used to place the conveyed workpiece, and also includes a material control component, a material receiving component and a material discharging component. The material control component can make the material frame 2 intermittently move at the conveying portion according to the set action, and the material receiving component can move the material frame 2 at the conveying portion upward in a stacked manner. The number of the material control components is several, and the material control component can maintain a set distance between two adjacent material frames 2. The material receiving component and the material discharging component are arranged front and back along the conveying direction of the conveying portion, and the material discharging component can grab the material frame 2 at the end of the conveying portion and send it to a set storage place.

[0025] The material control assembly is used to make the material frame 2 move intermittently at the conveying part according to a set method.

[0026] The receiving assembly can store the material frames 2 at the conveying part in a stacked manner, so that the space occupied by the several material frames 2 temporarily stored therein is relatively small. Of course, the material frames 2 at the uppermost part of the receiving part 9 can stably enter the detection operation place and the discharging place.

[0027] The material frame 2 on the conveying part that has not been picked up by the receiving part 9 continues to move along the conveying part. When this part of the material frame 2 enters the output end of the conveying part, it can be stably grasped and sent to the corresponding storage place under the action of the discharging component.

[0028] The two ends of the frame 1 are movably connected with a driving roller 3 and a driven roller 4 respectively, and also include a conveyor belt 5, which is sleeved on the driving roller 3 and the driven roller 4.

[0029] The active roller 3 is connected to an external driving member, such as a motor. When the motor drives the active roller 3 to rotate, the conveyor belt 5 can move smoothly.

[0030] The material control component includes a sensor 6 and a locking tongue structure, and the locking tongue structure and the sensor 6 are both connected to the frame 1 and adjacent to the conveyor belt 5.

[0031] The upper part of the conveyor belt 5 forms a conveying portion for conveying the material frame 2 .

[0032] In the initial state, the locking tongue structure is located at the conveyor belt 5 and can block the material frame 2 at the conveying part 5. When the sensor 6 detects that a material frame 2 passes through, the locking tongue structure can retract and make it separate from the conveying part. At this time, the material frame 2 at the conveying part can move smoothly.

[0033] The sensor 6 can detect whether a corresponding material frame 2 passes through the conveying part. The signal detected by the sensor 6 is judged by the system and then controlled by the lock tongue structure to determine whether the material frame 2 passes through.

[0034] The locking tongue structure comprises a cylinder and a stopper rod, wherein the stopper rod is fixedly connected to the piston rod of the cylinder, and in the initial state, the stopper rod is away from the conveying part. After the cylinder is actuated, the stopper rod is located at the conveying part, and the stopper rod can block the material frame.

[0035] The material receiving assembly includes a material receiving part 9 fixedly connected to the frame 1 and located directly above the conveying part. The interior of the material receiving part 9 is a cavity and a plurality of material frames 2 can be stored in the material receiving part 9 in a stacked manner. It also includes a lifting structure and a clamping structure. The lifting structure is connected to the frame 1, and the clamping structure is connected to the lifting structure. The clamping structure is located between the material receiving part 9 and the conveying part. The lifting structure is connected to the clamping structure and the lifting structure can drive the clamping structure to move up and down.

[0036] A plurality of material frames 2 stacked up and down in sequence reduces the occupied space, and the material frame 2 at the uppermost portion of the material receiving portion 9 can be stably and conveniently taken out, and during the taking out process, the material frame at this position will not interfere with the material frame at the conveying portion.

[0037] The lifting structure includes a bracket 10 and a driving member 11. The bracket 10 is fixedly connected to the frame 1 and is located directly above the conveying part. The driving member 11 is fixedly connected to the bracket 10 and is connected to the clamping structure.

[0038] After the clamping structure clamps the corresponding material frame 2, the driving member 11 can make the clamping structure move up and down stably.

[0039] The clamping structure includes a U-shaped base plate 12, a driving member 13 is fixedly connected to the U-shaped opening of the base plate 12, and a grab plate 14 is fixedly connected to the driving member 13. In the initial state, the grab plate 14 is away from the material frame 2. When the driving member 13 drives the grab plate 14 to move, the grab plate 14 can be supported at the bottom of the material frame 2.

[0040] After the second driving member 13 drives the grab plate 14 to move, the grab plate 14 can be brought into contact and connected with the material frame 2 to achieve grabbing of the material frame 2 .

[0041] The material receiving portion 9 has a one-way structure that can only allow the material frame 2 to move horizontally from bottom to top.

[0042] The one-way structure can prevent the material frame 2 from falling back after being moved upward.

[0043] The one-way structure includes a bottom plate 15, a latch tongue 16 and a latch slot 2a recessed at the bottom edge of the material frame 2. The bottom plate 18 is fixedly connected to the material receiving portion 9. The inner end of the latch tongue 16 is hinged to the upper portion of the bottom plate. The outer end of the latch tongue 16 extends out of the bottom plate 15. Under the action of its own gravity, the latch slot 2a of the material frame 2 rests against the outer end of the latch tongue 16.

[0044] The bayonet 2 a matches the outer end of the latch tongue 16 . Once the latch tongue 16 is inserted into the bayonet 2 a , the latch tongue 16 can support the material frame 2 . At this time, the material frame 2 cannot move downward.

[0045] When the material frame 2 moves upward, the latch tongue 16 can swing around its hinge and disengage from the material frame 2 under the pushing effect of the material frame 2. When the latch tongue 16 is directly opposite to the bayonet 2a, the latch tongue 16 returns to its original position and locks the material frame 2 again.

[0046] The lower portion of the outer end of the latch tongue 16 has a smoothly transitioning portion 16 a .

[0047] The transition portion 16a is a chamfer at the lower portion of the outer end of the latch tongue 16. Such a structure enables the outer end of the latch tongue 16 to be smoothly embedded in the bayonet 2a. Of course, it is also feasible that the transition portion 16a is a rounded corner at the lower portion of the outer end of the latch tongue 16.

[0048] The frame 1 is also fixedly connected with a grabbing mechanism, which is located at the upper part of the material receiving part 9. The grabbing mechanism can grab the material frame 2 at the uppermost end of the material receiving part 9, and the grabbed material frame 2 can be transferred to the inspection process and the discharging station.

[0049] The grabbing mechanism includes a transversely arranged guide rail 17, to which a slide plate 18 capable of translating along the guide rail 17 is connected, and the slide plate 18 has a manipulator 19 for grabbing the material frame 2, and the guide rail 17 is also connected to a driving member 20 capable of driving the slide plate 18 to translate.

[0050] The material frame 2 at the uppermost end of the material receiving portion 9 can be stably grasped by the grasping mechanism.

[0051] A second sensor 23 is provided at the upper part of the receiving part, and the second sensor 23 can detect whether there is a material frame at the upper part of the receiving part. If there is no material frame, the lifting structure cooperates with the clamping structure to grab a new material frame at the conveying part and send it into the receiving part.

[0052] Of course, after the lower part of the receiving part enters the new material frame, the one-way structure can prevent it from falling back. And the uppermost material frame is pushed by the lower material frame, and the uppermost material frame re-enters the second sensor position, ensuring that the upper part of the receiving part always has a fixed material frame in a state to be grabbed.

[0053] Although the system also has a manipulator, the manipulator in the technical solution is only responsible for grasping and will not make complex spatial trajectory movements. Compared with manipulators with complex movements, the manipulator in the technical solution is obviously simpler in structure and has a lower cost because it only realizes grasping.

[0054] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present invention, and are not intended to limit the present invention. As long as they are within the spirit of the present invention, appropriate changes and modifications to the above embodiments are within the scope of protection claimed by the present invention.
