[0050] The following is a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only for explaining and understanding the present invention, and are not used to limit the present invention.

[0051] As Figure 1 , Figure 2 , Figure 3 shown, the feeding device provided in this embodiment includes: a belt main body 100, a position detection member 200, a blowing member 300, and an adsorption member 400; the material 10 is placed on the belt main body 100, and the belt main body 100 drives the material 10 to move, thereby transporting the material 10.

[0052] The position detection member 200 forms a detection area. Specifically, the position detection member 200 includes two opposed sensors, which are respectively arranged on the left and right sides of the belt main body 100. A detection area is formed between the two opposed sensors. When the material 10 enters the detection area, the material 10 can be sensed, and a control signal is generated and transmitted to the external controller. The external controller controls the belt main body 100 to stop working, and the material 10 can be transported in place.

[0053] The blowing member 300 is arranged above the belt main body 100, and the blowing member 300 is configured to be able to blow air toward the detection area, so that the film under the material 10 in the detection area is closely attached to the belt main body 100.

[0054] Regarding the structure and shape of the blowing member 300, specifically:

[0055] The blowing member 300 includes a blowing nozzle 310 and a positive pressure air source 320; the blowing nozzle 310 is located above the belt main body 100, and the blowing direction of the blowing nozzle 310 is toward the detection area; the positive pressure air source 320 is connected to the blowing nozzle 310, and the positive pressure air source 320 conveys positive pressure gas to the blowing nozzle 310 and sprays it through the blowing nozzle 310. The gas sprayed by the blowing nozzle 310 can blow toward the material 10 in the detection area, so that the film under the material 10 is closely attached to the belt main body 100, and the film is closely attached and flat.

[0056] In addition, optionally, a plurality of blowing nozzles 310 may also be provided, and the blowing directions of the plurality of blowing nozzles 310 are different, so that the positive pressure gas blows toward the entire area of the belt main body 100, so that during the process of the material 10 being transported by the belt main body 100, the film under the material 10 can always be closely and flatly attached to the belt main body 100.

[0057] The belt main body 100 has adsorption holes 110, and a plurality of adsorption holes 110 are provided. The plurality of adsorption holes 110 are arranged in an array. The adsorption member 400 is configured to be able to transmit negative pressure through the adsorption holes 110 so that the material 10 is closely attached to the belt main body 100.

[0058] Regarding the structure and shape of the adsorption member 400, specifically:

[0059] The adsorption member 400 includes a vacuum cavity 410 and a vacuum air source 420; the vacuum cavity 410 is arranged in the inner cavity formed by enclosing the belt main body 100. The vacuum cavity 410 is of a box structure with an opening at the top, and the opening faces the belt main body 100 located above. A vacuum chamber is formed inside the vacuum cavity 410; the vacuum air source 420 is connected to the vacuum cavity 410, and the vacuum air source 420 evacuates to form a negative pressure in the vacuum chamber, so as to transmit the negative pressure to the film under the material 10 on the belt main body 100 through the adsorption holes 110.

[0060] In an alternative embodiment, the vacuum chamber covers the detection area so that the film under the material 10 entering the detection area is always adsorbed inside the vacuum belt.

[0061] In addition, optionally, the vacuum chamber can also cover the entire area of the belt main body 100, so that during the transportation of the material 10 by the belt main body 100, the film under the material 10 can always be adsorbed on the belt main body 100.

[0062] The feeding device provided in this embodiment transmits the negative pressure generated by the adsorption member 400 through the adsorption holes 110 to closely attach the material 10 to the belt main body 100, so that it is not easy to generate frictional static electricity between the material 10 and the belt main body 100, effectively avoiding the film bulge caused by static electricity. And, by blowing air towards the detection area formed by the in-place detection member 200 through the blowing member 300, the film on the material 10 located in the detection area is closely attached to the surface of the material 10, so as to flatten the film, alleviating the technical problems existing in the prior art that the transportation of the material 10 with a film uses a flat belt for transportation, which is easy to generate static electricity when contacting the film, resulting in the film bulge, and the uneven film causes the detection laser to reflect on the film surface, affecting the detection accuracy of the sensor.

[0063] In an alternative embodiment, in order to install the belt main body 100, the in-place detection member 200 and the adsorption member 400, the feeding device further includes two mounting frames 510 arranged in parallel; a rotating roller 120 is arranged between the two mounting frames 510, and both ends of the rotating roller 120 are rotatably connected to the two mounting frames 510 respectively, so that the rotating roller 120 can rotate along its own axis direction, and the belt main body 100 is wound around the rotating roller 120, thereby installing the belt main body 100.

[0064] The vacuum chamber 410 is located between two mounting brackets 510, and the vacuum chamber 410 is respectively connected to the two mounting brackets 510 to install the vacuum chamber 410.

[0065] Two opposed sensors are arranged relatively parallel, and the two opposed sensors are relatively mounted on the two mounting brackets 510.

[0066] In addition, a connecting bracket 520 is provided below the two mounting brackets 510. The connecting bracket 520 is respectively connected to the two mounting brackets 510, so as to connect the two mounting brackets 510 into an integral structure and ensure the stability of the mounting brackets 510.

[0067] In order to ensure that the position where each material 10 stops each time is the same, in an alternative embodiment, the feeding device further includes a positioning adjustment member 600; the positioning adjustment member 600 is located in the conveying direction of the belt main body 100, and the positioning adjustment member 600 is used to block the movement of the material 10 sensed by the positioning detection member 200, so as to stop the material 10 and facilitate the subsequent robot to pick up the material 10.

[0068] It should be noted that when the positioning detection member 200 senses the material 10, the positioning detection member 200 generates a control signal to control the belt main body 100 to stop working. There is a time interval between when the positioning detection member 200 senses the material 10 and when the belt main body 100 stops working, that is, when the positioning detection member 200 senses the material 10, the belt main body 100 stops working after a period of time. Therefore, when the positioning detection member 200 senses the material 10, the material 10 will continue to move for a period of time. Therefore, the positioning adjustment member 600 is provided to realize that when the positioning detection member 200 senses the material 10, the positioning adjustment member 600 stops the continuously moving material 10.

[0069] In addition, in order to ensure that the position where it stops each time is the same, it is necessary to ensure that the material 10 can all contact the positioning adjustment member 600 and the material 10 can all be stopped by the positioning adjustment member 600. When the positioning detection member 200 senses the material 10, the material 10 will continue to move for a period of time and still cannot contact the positioning adjustment member 600. At this time, it is necessary to extend the continuous working time of the belt main body 100, so as to ensure that the material 10 can all be stopped by the positioning adjustment member 600 each time.

[0070] Regarding the structure and shape of the positioning adjustment member 600, specifically:

[0071] The in-place adjustment member 600 includes an adjustment driving member 610 and a blocking member 620; the adjustment driving member 610 is set as any one of a driving motor, a driving hydraulic cylinder or a driving air cylinder. Preferably, the adjustment driving member 610 is set as a driving air cylinder. The adjustment driving member 610 is connected to the mounting bracket 510. The blocking member 620 is specifically an L-shaped baffle structure. The adjustment driving member 610 is drivingly connected to the vertical plate of the blocking member 620. The horizontal plate of the blocking member 620 is used to contact the material 10.

[0072] The driving force generated by the adjustment driving member 610 can drive the blocking member 620 to move between a blocking position and an avoidance position; when the driving rod of the adjustment driving member 610 extends, the blocking member 620 is in the blocking position, and the blocking member 620 can block the movement of the material 10 sensed by the in-place detection member 200; when the material 10 stops moving, the driving rod of the adjustment driving member 610 retracts, so that the blocking member 620 is in the avoidance position, and there is a distance between the blocking member 620 and the material 10 sensed by the in-place detection member 200, which is convenient for the subsequent robotic arm to grab the material 10 sensed by the in-place detection member 200.

[0073] As Figure 3 shown, in an alternative embodiment, the feeding device further includes a belt power assembly 700; the belt power assembly 700 is connected to the mounting bracket 510, and the belt power assembly 700 is used to drive the movement of the belt body 100.

[0074] Specifically, the belt power assembly 700 includes a belt driving member 710 and a belt driving roller 720. The belt driving member 710 is drivingly connected to the belt driving roller 720. The driving force generated by the belt driving member 710 drives the belt driving roller 720 to rotate along its own axis. Since the belt body 100 is wound around the belt driving roller 720, the rotation of the belt driving roller 720 drives the movement of the belt body 100, thereby transporting the material 10.

[0075] In an alternative embodiment, the feeding device further includes a width adjustment plate 800 disposed above the belt body 100; the width adjustment plate 800 can contact the material 10 on the belt body 100 to adjust the orientation of the material 10. The two width adjustment plates 800 are respectively slidably connected to the two mounting brackets 510 to adjust the distance between the two width adjustment plates 800.

[0076] Specifically, a long slot 810 is formed in the width adjustment plate 800. The depth direction of the long slot 810 is the width direction of the belt main body 100. A connection hole is provided on the mounting bracket 510. Bolts pass through the long slot 810 and the connection hole to connect the width adjustment plate 800 to the mounting bracket 510. Due to the setting of the long slot 810, the position of the width adjustment plate 800 relative to the mounting bracket 510 can be freely adjusted, so as to adjust the distance between the two width adjustment plates 800, which is applicable to materials 10 of different width dimensions.

[0077] The feeding device provided in this embodiment can blow the film from above to be closely attached and flattened to the belt main body 100 through the blowing member 300; through the adsorption member 400, the film can be sucked from below to be closely attached to the belt; through the setting of the in-place adjustment member 600, it is ensured that the position where the material 10 stops each time is the same, so as to facilitate the subsequent manipulator to grab the material 10.

[0078] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
