Description

Technical Field

[0001] This utility model relates to the field of suction cup feeding technology, and in particular to a material-grabbing suction cup mechanism. Background Technology

[0002] In the FPC industry, the current material-grabbing suction cup mechanism that picks up a stack of alternating products to be processed and partition paper is generally composed of a negative pressure suction nozzle. However, since the partition paper is made of ordinary paper material and has air-permeable properties, while the products to be processed do not have air-permeable properties, when using a negative pressure suction cup to pick up materials, the air-permeable properties of the partition paper may cause the products under the partition paper to be picked up as well, resulting in incorrect material placement and affecting production and processing.

[0003] The technical problem to be solved by this application is: to design a suction cup mechanism that can pick up the product to be processed and the separator paper one by one. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a suction cup mechanism that can pick up the product to be processed and the separator paper one by one.

[0005] The technical solution adopted by this utility model is as follows: a material-picking suction cup mechanism, including a mounting main board, which is provided with a plurality of positive pressure suction cups for picking up paper and negative pressure suction nozzles for picking up products to be processed. The mounting main board is also provided with a lifting mechanism for driving the positive pressure suction cups to rise and fall, and the mounting main board is also provided with a material detection sensor fixedly connected thereto for identifying the type of material.

[0006] In some embodiments, the positive pressure suction cup includes an outer shell, an air outlet channel located in the middle of the outer shell, and an inner seat connected to the outer shell. An airflow groove is formed between the outer shell and the inner seat, and the airflow groove communicates with the bottom of the positive pressure suction cup to the outside.

[0007] In some embodiments, one end of the air outlet channel extends to the inner seat, and the inner seat has a plurality of airflow channels inside, with the two ends of the airflow channels connected to the air outlet channel and the airflow groove, respectively.

[0008] In some embodiments, the lifting mechanism includes a guide cylinder disposed on the surface of the mounting main board, a connecting plate connected to the drive end of the guide cylinder, the connecting plate being L-shaped, and a positive pressure suction cup having a connecting suction rod fixedly connected thereto, the connecting suction rod being fixedly connected to the connecting plate.

[0009] In some embodiments, the negative pressure nozzle is provided with an air suction tube connected thereto, and the top end of the air suction tube is provided with a T-connector.

[0010] In some implementations, the mounting motherboard is also provided with several manifold blocks, which are connected to the tee connectors.

[0011] In some implementations, the material sensor is signal-connected to the guide cylinder.

[0012] This invention has the following technical advantages: By equipping the mainboard with several positive pressure suction cups and negative pressure suction nozzles, and by also equipping the mainboard with a material detection sensor for identifying the type of material, when picking up material, the material detection sensor first identifies whether the material to be picked up is the product to be processed or the separator paper. If it is identified as separator paper, the lifting mechanism drives the positive pressure suction cups to descend and pick up the separator paper. If it is identified as the product to be processed, the negative pressure suction nozzle picks up the material. By using positive pressure suction cups and negative pressure suction nozzles to pick up separator paper and product to be processed respectively, the phenomenon of picking up the product below along with the separator paper can be avoided, thereby avoiding production and processing errors.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4This utility model provides a technical solution: a material-grabbing suction cup mechanism, including a mounting main board 1, a connecting transition plate 7 on the mounting main board 1, wherein the connecting transition plate 7 is provided with a driving device for driving the overall lifting of the mounting main board 1, the driving device including but not limited to driving actuators such as lifting cylinders, a plurality of positive pressure suction cups 2 and negative pressure suction nozzles 3 are provided on the mounting main board 1, the mounting main board 1 is also provided with a lifting mechanism 4 for driving the positive pressure suction cups 2 to lift, and a material detection sensor 5 for identifying the type of material is also provided on the mounting main board 1, wherein the positive pressure suction cup 2 includes a housing 20, an air outlet channel 21 located in the middle of the housing 20, and a connection to the housing 20. The inner seat 22 is located inside the outer shell 20. The gap between the inner seat 22 and the outer shell 20 forms an airflow groove 23, which is connected to the outside of the bottom of the positive pressure suction cup 2. One end of the air outlet channel 21 extends to the inner seat 22, and the end of the air outlet channel 21 inside the inner seat 22 is closed. Several airflow channels 220 are provided inside the inner seat 22, and the two ends of the airflow channels 220 are connected to the air outlet channel 21 and the airflow groove 23, respectively. Therefore, when it is necessary to pick up materials, the main board 1 is first driven to descend as a whole by the drive device. When the positive pressure suction cup 2 and the negative pressure suction nozzle 3 are about to contact the paper separator, the drive device stops. The system drives the positive pressure suction cup 2, then uses the material detection sensor 5 to detect whether the material on the top layer is a separator or the product to be processed. If it is a separator, the material detection sensor 5 sends a signal to the lifting mechanism 4, which then drives the positive pressure suction cup 2 to descend, so that the lower surface of the positive pressure suction cup 2 is about 3-5mm away from the separator. At this time, the lower surface of the positive pressure suction cup 2 is lower than the lower surface of the negative pressure suction nozzle 3. Then, when gas is injected into the air outlet channel 21, the gas flows into the air outlet groove 23 through the air outlet channel 220, and then blows out from the bottom of the positive pressure suction cup 2 after passing through the air outlet groove 23. The air outlet groove 23 is annular inside the positive pressure suction cup 2. The outlet of 3 is an annular outlet at the bottom of the positive pressure suction cup 2, so the airflow also flows out in an annular shape. According to Bernoulli's principle, the outlet of the airflow channel 23 is in a high-pressure state, while the middle of the annular outlet of the airflow channel 23, which is directly below the inner seat 22, is in a low-pressure state. Since the product to be processed is below the partition paper, and the product to be processed does not have air permeability, the airflow blown out from the airflow channel 23 is blocked by the product to be processed. At this time, the airflow will pass through the partition paper and be blocked by the product, and then pass through the partition paper again and flow to the middle of the annular outlet of the airflow channel 23. It is equivalent to the airflow flowing from the high-pressure area to the low-pressure area, thereby generating an adsorption force to adsorb and pick up the material from the partition paper.

[0020] The lifting mechanism 4 includes a guide cylinder 40 mounted on the surface of the mounting main board 1 and a connecting plate 41 connected to the drive end of the guide cylinder 40. The connecting plate 41 is L-shaped. The top of the positive pressure suction cup 2 is provided with a connecting suction rod 24 fixedly connected to it. The connecting suction rod 24 is hollow and its interior is connected to the air outlet channel 21. Gas can be injected into the air outlet channel 21 by connecting the connecting suction rod 24 to the air pipe. The connecting suction rod 24 is fixedly connected to the connecting plate 41. The positive pressure suction cup 2 can be lifted and lowered by driving the connecting plate 41 through the guide cylinder 40.

[0021] The negative pressure suction nozzle 3 is connected to a suction pipe 30, and a three-way connector 31 is provided at the top of the suction pipe 30. Several manifold blocks 6 are also provided on the mounting main board 1. The manifold blocks 6 are connected to the three-way connector 31. By providing the manifold blocks 6, the three-way connector 31 can be connected to an external vacuum source, so that the negative pressure suction nozzle 3 can vacuum and adsorb materials. When the material detection sensor 5 detects that the material below is the product to be processed, the guide cylinder 40 drives the positive pressure suction cup 2 to rise, so that the lower surface of the positive pressure suction cup 2 is higher than the lower surface of the negative pressure suction nozzle 3. Then, the driving device drives the entire mounting main board 1 to descend, so that the lower surface of the negative pressure suction nozzle 3 can contact the surface of the product to be processed. Then, the negative pressure suction nozzle 3 is used to vacuum and adsorb the product to be processed.

[0022] In order to enable the guide cylinder 40 to drive the positive pressure suction cup 2 to rise and fall in a timely manner, the material detection sensor 5 is connected to the guide cylinder 40. When the material detection sensor 5 detects the material below, it can send a corresponding signal to the guide cylinder 40 to control the rise and fall of the positive pressure suction cup 2.

[0023] The working principle of this utility model is as follows: Several positive pressure suction cups 2 and negative pressure suction nozzles 3 are respectively provided on the mounting main board 1, and a material detection sensor 5 for identifying the type of material is also provided on the mounting main board 1. When picking up materials, the material detection sensor 5 first identifies whether the material to be picked up is the product to be processed or the partition paper. If it is identified as partition paper, the lifting mechanism 4 drives the positive pressure suction cup 2 to descend and pick up the partition paper. If it is identified as the product to be processed, the negative pressure suction nozzle 3 picks up the material. By using the positive pressure suction cup 2 and the negative pressure suction nozzle 3 to pick up the partition paper and the product to be processed respectively, the phenomenon of picking up the product below when picking up the partition paper can be avoided, thereby avoiding production and processing errors.

[0024] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
