[0002] At present, for the appearance of the raw material products of mobile phone middle frames, the yield of customer-supplied materials is not high, and the types and quantities of defective products are relatively large. After passing through the detection equipment, it is necessary to subdivide the types of defective products and require that the appearance of the defective products cannot cause secondary damage, so as to facilitate subsequent secondary repair and use. At present, most appearance detection equipment places the products on the conveyor belt after detection, and the products are sent to different positions through the conveyor belt, and the air cylinders are used to push the products into the defective product collection box, so as to achieve the effect of product classification. The above-mentioned material storage method has the following disadvantages:

[0003] (1) Using the air cylinder to push the products, and then the products slide down the slope to the defective product collection box. During the process of sliding towards the defective product box, the products collide with each other, which is likely to cause secondary damage to the appearance of the products;

[0004] (2) Because the number of defective products is large, in order to reduce secondary damage such as secondary collision, scratching, chemical damage, and pressing damage to the appearance of the defective products, it is necessary for someone to always stay at the defective product outlet to collect materials in real time, and collect them frequently, which wastes human resources;

[0005] (3) The defective products are likely to accumulate in the defective product box, forming a "small mountain", which not only wastes the storage space of the defective product box, but also requires manual smoothing of the "small mountain" in time. During the manual smoothing process, the defective products will also collide with each other, causing secondary damage;

[0006] (4) The defective product box cannot store materials for a long time, and manual collection is required frequently. Summary of the Utility Model

[0037] As Figures 1 to 6 shown, a multi-layer sorting and storage mechanism is installed at the tail of the belt assembly and in front of the receiving station, and is used for sorting and storing the workpiece 1. It includes three sorting and storage units. The sorting and storage unit includes a waste removal cylinder assembly and a multi-layer bin storage assembly arranged in one-to-one correspondence. A transition plate 21 is provided between the waste removal cylinder assembly and the multi-layer bin storage assembly;

[0038] The belt assembly includes a ribbed synchronous belt 8 for conveying the workpiece 1;

[0039] The multi-layer material storage component includes a bin frame 3, and two detachable bins 14 are provided on the bin frame 3. The first cylinder 2 of the waste removal cylinder component first pushes the workpiece 1 through the transition plate 21 and then into the bin 14.

[0040] A lifting component for driving the bin frame 3 to move up and down is provided below the bin frame 3.

[0041] The transition plate 21 is set lower than the ribbed synchronous belt 8, and the bottom plate of the bin 14 is set lower than the transition plate 21; the distance H1 between the ribbed synchronous belt 8 and the transition plate 21 is 1 mm, and the distance H2 between the transition plate 21 and the bottom plate of the bin 14 is 0.7 mm. The ribbed synchronous belt 8, the transition plate 21, and the bottom plate of the bin 14 are set at different heights and there are distances, which can ensure that the workpiece 1 is smoothly pushed out from the ribbed synchronous belt 8, passes through the transition plate 21, and finally falls onto the bottom plate of the bin 14, preventing the workpiece 1 from jamming in the transition area between the ribbed synchronous belt 8 and the transition plate 21 and the transition area between the transition plate 21 and the bottom plate of the bin 14.

[0042] The multi-layer material storage component further includes a baffle 5. The upper end of the baffle 5 is rotatably installed on the first-layer bin 14, the lower end of the baffle 5 extends to the last-layer bin 14, and the baffle 5 is arranged away from the first cylinder 2.

[0043] The lifting component includes a second cylinder 18, and a lifting plate 16 and a bottom plate 15 arranged up and down. Guide shafts 17 are provided at the four corners of the bottom plate 15. The lifting plate 16 is sleeved on the guide shafts 17 and the lifting plate 16 is located below the bin frame 3. The rod of the second cylinder 18 is connected to the lifting plate 16. When the rod of the second cylinder 18 extends, it lifts the lifting plate 16 and further lifts the bin frame 3, so that the bin 14 rises to the target height.

[0044] Linear bearings 20 are provided on the lifting plate 16, and the guide shafts 17 pass through the linear bearings 20; a second cylinder speed control valve 19 is provided on the second cylinder 18. The second cylinder speed control valve 19 can adjust the working speed of the second cylinder 18.

[0045] Teflon tape layers are respectively provided on the transition plate 21 and the bottom plate of the bin 14.

[0046] The waste removal cylinder component further includes a pusher plate 11, and the pusher plate 11 is installed at the rod end of the first cylinder 2; a fiber optic sensor 12 for detecting whether the workpiece 1 is in place is provided on the pusher plate 11, and a first cylinder speed control valve 13 is provided on the first cylinder 2. The first cylinder speed control valve 13 can adjust the working speed of the first cylinder 2.

[0047] The belt assembly further includes a driving pulley 6 and a driven pulley 7 that drive the ribbed synchronous belt 8 to work. The driving pulley 6 and the driven pulley 7 are respectively located at both ends of the ribbed synchronous belt 8. The belt assembly further includes a first sensor 9 and a second sensor 10, and the first sensor 9 and the second sensor 10 are respectively installed on the outer side of the ribbed synchronous belt 8. The first sensor 9 is used to sense whether the ribs of the ribbed synchronous belt 8 are in place. If in place, the workpiece 1 is loaded. The second sensor 10 is convenient for detecting whether there is a workpiece 1 between two ribs. If there is a workpiece 1, the subsequent material removal operation of the first cylinder 2 is carried out.

[0048] A good product receiving plate 4 is provided at the tail output end of the belt assembly, which is convenient for receiving good products.

[0049] The working process of this multi-layer storage and feeding mechanism is specifically as follows:

[0050] (1). In the multi-layer material storage component, the first-layer bin 14 rises to the target height, and the bottom plate of the first-layer bin 14 is slightly lower than the transition plate 21, and the preparatory work is done.

[0051] (2). According to the detection results of the previous process detection equipment and the types of defective products, the corresponding material removal and storage unit works. After the fiber optic sensor 12 in the material removal and storage unit detects that the workpiece 1 is in place, the first cylinder 2 works, the push plate 11 extends, and the workpiece 1 is pushed through the transition plate 21 and then pushed into the first-layer bin 14 until the first-layer bin 14 is filled with workpieces 1.

[0052] (3). After the first-layer bin 14 is filled, the second cylinder 18 works, and the lifting bin frame 3 is lifted through the lifting plate 16, so that the bottom plate of the second-layer bin 14 is slightly lower than the transition plate 21. The first cylinder 2 works, and the workpiece 1 is pushed through the transition plate 21 and then pushed into the second-layer bin 14 until the second-layer bin 14 is filled with workpieces 1. During the process of loading the workpiece 1 into the second-layer bin 14, the first-layer bin 14 can be replaced, the full bin 14 is taken out, and an empty bin 14 is replaced.

[0053] (4). After the second-layer bin 14 is filled, the ejector rod of the second cylinder 18 retracts, and the bin frame 3 descends, so that the bottom plate of the first-layer bin 14 is slightly lower than the transition plate 21, and the first-layer bin 14 continues to carry out the material storage work. At this time, the rotating baffle 5 can be rotated to take out the filled second-layer bin 14.

[0054] This multi-layer storage and feeding mechanism has a simple structure and is easy to operate, and has the following advantages:

[0055] (1). Multiple material removal and storage units are set according to the grading of defective products, and the grading effect is good.

[0056] (2) The multi-layer material storage component includes a bin frame 3, on which there are multiple layers of detachable bins 14. The first cylinder 2 first pushes the workpiece 1 past the transition plate and then into the bin. The workpieces are arranged in a single layer on the bin, and the workpieces will not collide with each other, avoiding secondary damage to the appearance of the workpieces.

[0057] (3) After the first layer of bins in the bin frame is filled with workpieces, the ejector rod of the second cylinder 18 extends to lift the bin frame 3, and the second layer of bins is slightly lower than the transition plate 21. The first cylinder 2 continues to push the workpieces into the second layer of bins, facilitating long-term storage of workpieces without the need for frequent manual material collection.
