At this time, the conveying mechanism picks up the outermost material and transports it to the next position. Since the materials are separated by inputting high-pressure gas before the materials are transported away, adhesion can be avoided during the transportation of the materials, and feeding errors can be avoided.

[0036] See also Figure 1 and Figure 2 Now, the feeding mechanism provided in the embodiment of the present application is described. The feeding mechanism provided in the embodiment of the present application is used to feed the material 90 .
[0037] Among them, refer to Figure 1 , the material 90 is in the form of a sheet and is provided with a through hole 91. The material 90 is in the form of a sheet, and its outer shape may be a rectangular, circular, polygonal or other shape. The material 90 is also provided with a through hole 91, and the shape of the through hole 91 may be a circular, rectangular, polygonal or other shape. If the outer shape of the material 90 is circular and the through hole 91 is circular, the material 90 is in the form of a ring. If the outer shape of the material 90 is square and the through hole 91 is circular, the material 90 is in the form of a square sheet with a circular hole. If the outer shape of the material 90 is circular and the through hole 91 is square, the material 90 is in the form of a circular sheet with a square hole. Hereinafter, the material 90 is explained by taking the outer shape of the material 90 as a circular shape and a ring shape with a through hole 91 as an example. Specifically, the material 90 is made of metal, that is, the material 90 is a metal ring.
[0038] The feeding mechanism includes a feeding component 10 and a material moving component 20 .
[0039] Reference Figure 3 , multiple materials 90 can be stacked and sleeved on the feeding piece 10, and the feeding piece 10 is provided with an air channel 11. The air inlet 111 of the air channel 11 is provided at one end of the feeding piece 10 and is used to connect the high-pressure air source. The air outlet 112 of the air channel 11 is provided on the side of the other end of the feeding piece 10, and the length of the air outlet 112 along the axial direction of the feeding piece 10 is greater than the thickness of the material 90 along the axial direction. The feeding piece 10 is in the shape of a rod, and its outer diameter matches the inner diameter of the through hole 91 of the material 90, so that the material 90 can be sleeved on the feeding piece 10. Since the feeding piece 10 has a certain length and the material 90 is in the shape of a sheet, multiple materials 90 can be stacked and sleeved on the feeding piece 10 at one time. The feeding piece 10 can be placed vertically, horizontally, or tilted. The following takes the vertical placement of the feeding piece 10 as an example for explanation.
[0040] It can be understood that the shape of the feeding piece 10 is adapted to the shape of the through hole 91, so that the material 90 can move along the feeding piece 10. For example, if the through hole 91 is circular, the cross-sectional shape of the feeding piece 10 is circular; if the through hole 91 is rectangular, the cross-sectional shape of the feeding piece 10 is rectangular.
[0041] Reference Figure 2, an air passage 11 is provided in the feeding member 10, and an air inlet 111 and an air outlet 112 of the air passage 11 are respectively located at the two ends of the feeding member 10. Specifically, the feeding member 10 is placed vertically, and a plurality of materials 90 are attached to each other (i.e., stacked) on the feeding member 10 due to the effect of gravity. The air inlet 111 is provided at the lower end of the feeding member 10, and the air outlet 112 is provided at the upper end of the feeding member 10. The air inlet 111 is connected to a high-pressure gas source, which may be an air pump or an air supply system of a production workshop. The air outlet 112 is provided on the peripheral surface of the feeding member 10. If the stacked material 90 is located at the air outlet 112, the high-pressure gas ejected from the air outlet 112 may pass through between two stacked materials 90 to separate the two materials 90.
[0042] The length of the air outlet 112 along the axial direction of the feeding member 10 is greater than the thickness of the material 90 along the axial direction, ensuring that the air outlet 112 can at least separate two stacked materials 90 (ie, the topmost and the second material 90).
[0043] Reference Figure 6 and Figure 7 The material moving assembly 20 includes a pusher 21 and a driver 22. The pusher 21 is provided with an opening 211 for the feeding member 10 to pass through. The pusher 21 can move along the axial direction of the feeding member 10. The driver 22 can drive the pusher 21 to move so as to push the material 90 stacked on the feeding member 10 to the end of the feeding member 10 provided with the air outlet 112 to cover the air outlet 112. The pusher 21 is sleeved on the feeding member 10. It can be driven by the driver 22 to move from one end of the feeding member 10 to the other end. When a plurality of materials 90 are sleeved on the feeding member 10, the movement of the pusher 21 will push the plurality of materials 90 together, so that the materials 90 move on the feeding member 10 to the end of the feeding member 10 provided with the air outlet 112. It can be understood that the pusher 21 is located on the side of the material 90 on the feeding member 10 away from the air outlet 112. When the feeding member 10 is placed vertically, with the air outlet 112 at the top and the air inlet 111 at the bottom, the pusher 21 is below the material 90, and the stacked material 90 falls on the pusher 21 under the action of gravity. The driver 22 can drive the pusher 21 to carry the material 90 upward, so that the stacked material 90 moves to the upper end of the feeding member 10, and at this time, the stacked material 90 is sheathed on the outside of the air outlet 112 (the air outlet 112 is located on the peripheral surface).
[0044] The air inlet 111 inputs high-pressure gas when the conveying mechanism presses down to pick up a material 90. When the pusher 21 pushes the material 90 to the end of the feeding member 10 provided with the air outlet 112, the conveying mechanism can come over to pick up the material 90 at the outermost end (for example, the material 90 at the top). When the conveying mechanism presses down on the material 90, the stacked material 90 is supported by the pusher 21 at the bottom and pressed down by the conveying mechanism at the top, so that the stacked material 90 forms a closed cavity. At this time, the air inlet 111 inputs high-pressure gas, and the high-pressure gas opens the cavity, so that the materials 90 that are attached to each other are separated by the gas, and then the conveying mechanism takes away the top material 90. That is, the materials 90 are separated by inputting high-pressure gas between the stacked materials 90. The conveying mechanism can be a manipulator, and the manipulator can use a suction cup or a clamping finger to pick up the material 90.
[0045] Reference Figure 7 Specifically, the driver 22 can be a screw mechanism, which may include a motor, a screw and a nut mounted on the screw. The motor drives the screw to rotate, thereby driving the nut to rise and fall. The nut is connected to the push piece 21, thereby driving the push piece 21 to push the material 90.
[0046] Reference Figure 1 and Figure 2 The air outlet 112 includes a first air outlet hole 1121 provided on the end surface of the feeding member 10 and an air outlet groove 1122 provided on the end surface. The air outlet groove 1122 is connected to the first air outlet hole 1121, and both ends of the air outlet groove 1122 pass through the peripheral surface of the feeding member 10. The compressed air in the air passage 11 is guided to the air outlet groove 1122 through the first air outlet hole 1121, and then discharged from the peripheral surface of the feeding member 10 from the air outlet groove 1122, thereby separating the laminated materials 90 sleeved outside the feeding member 10 to avoid mutual adhesion. It should be noted that since the first air outlet hole 1121 is provided on the end surface of the feeding member 10, when the conveying mechanism conveys the material 90, the picking structure of the conveying mechanism needs to block the end of the first air outlet hole 1121 to prevent the high-pressure gas from being discharged from the end of the first air outlet hole 1121.
[0047] Reference Figure 2 and Figure 3 The depth of the gas outlet groove 1122 along the axial direction of the feeding piece 10 is greater than the thickness of the material 90 along the axial direction, so as to ensure that the gas outlet groove 1122 can be opposite to the gap between the two pieces of material 90 and input the high-pressure gas into the gap between the two pieces of material 90.
[0048] Reference Figure 4 and Figure 5The feeding mechanism also includes a feeding string 30, which includes a gripping portion 31, a feeding rod 32, a protrusion 33 and a plug 34 connected in sequence. The feeding rod 32 can be stacked with multiple materials 90, and the plug 34 can be removably inserted into the first air outlet 1121. The protrusion 33 can be at least partially embedded in the air outlet groove 1122. The plug is coaxial with the feeding rod 32. The size of the gripping portion 31 along the first direction is greater than the outer diameter of the feeding rod 32, and the first direction is perpendicular to the axial direction of the feeding rod 32. The loading string 30 can be used to set multiple materials 90. Specifically, multiple materials 90 can be set on the loading rod 32 manually, and then the loaded loading string 30 is turned upside down and inserted into the feeding member 12 (the pusher 21 on the feeding member 12 has been lowered to the bottom in advance), that is, the plug 34 and the protrusion 33 are respectively inserted into the first air outlet 1121 and the air outlet groove 1122. At this time, the feeding rod 12 and the loading rod 32 are coaxial, and the material 90 on the loading rod 32 can be transferred to the feeding rod 12 along the loading rod 32. That is, through the loading string 30, multiple materials 90 can be stacked and set on the feeding member 10 in turn, which greatly improves the efficiency of switching materials 90 of the feeding member 10.
[0049] Reference Figure 1 and Figure 2 The feeding member 10 includes a feeding rod 12, a base 13 and an air nozzle 14 connected in sequence. The air channel 11 is arranged in the feeding rod 12 and the base 13. The air inlet 111 is arranged in the base 13 and communicated with the air nozzle 14. The air outlet 112 is arranged at the end of the feeding rod 12 away from the base 13. The shape of the base 13 is adapted to the shape of the opening 211 so that the opening 211 can pass through the base 13. The base 13 is used to support and fix the feeding rod 12. The feeding rod 12 can be placed on a table or installed on a corresponding workstation through the base 13. The air channel 11 is arranged in the feeding rod 12 and the base 13. The air nozzle 14 is connected to the high-pressure gas source through an air pipe to input the high-pressure gas from the air channel 11 to the air outlet 112 of the feeding rod 12. The shape of the base 13 is adapted to the shape of the opening 211, so that the pusher 21 can be lowered to make the opening 211 stuck under the base 13, so that the feeding rod 12 can accommodate more materials 90.
[0050] Reference Figure 1 and Figure 3 The feeding mechanism also includes a gasket 40, which is matched and mounted on the feeding member 10 and can move along the feeding member 10. The gasket 40 is located between the pusher 21 and the material 90, and the pusher 21 pushes the gasket 40 to move the material 90. The material 90 can fit with the gasket 40 on the feeding member 10, and can move as a whole when the gasket 40 moves. The push of the material 90 is holistic and uniform. The gasket 40 can assist the pusher 21, can better support the material 90, and push the material 90. The gasket 40 is in a circular ring shape, and the pusher 21 is in a fork shape. A shift fork can be used as the pusher 21.
[0051] Reference Figure 6 and Figure 7 The feeding mechanism also includes a material sensor 50, which is arranged on one side of the feeding member 10 and corresponds to the end of the feeding member 10 provided with the air outlet 112. The material sensor 50 is used to detect whether there is material 90 at the end of the end of the feeding member 10 provided with the air outlet 112. The driver 22 drives the pusher 21 to push the material 90 when the material sensor 50 detects that there is no material 90. After the conveying mechanism picks up and carries away the material 90 located at the top, the material sensor 50 detects that there is no material 90 at the top of the upper feeding member 10, and the driver 22 drives the pusher 21 to push the material 90 up until the material 90 is lifted to the top of the material rod and is detected by the material sensor 50, and the driving of the driver 22 is stopped. Through the cooperation between the material 90 passing through the device and the driver 22, the material 90 can be continuously lifted upward, so that the conveying mechanism can pick up the material 90, and the height of the conveying mechanism is consistent each time it descends.
[0052] Reference Figure 6 and Figure 7 The feeding mechanism further includes a position sensor 60, which is disposed at the end of the end of the feeding member 10 provided with the air outlet 112. The position sensor 60 is used to detect whether the pusher 21 reaches the end of the end of the feeding member 10 provided with the air outlet 112. When the position sensor 60 detects the pusher 21, the driver 22 stops driving the pusher 21. The position sensor 60 is used to detect the position of the pusher 21. As the conveying mechanism continuously conveys the material 90 on the main feeding member 10, the driver 22 continuously lifts the pusher 21 until all the material 90 is taken away. However, since all the material 90 is taken away, the material sensor 50 does not sense the material 90, and the driver 22 still lifts the pusher 21 and does not stop. Only when the pusher 21 continues to rise until it is detected by the position sensor 60, the driver 22 stops driving the pusher 21.
[0053] Reference Figure 6 and Figure 7 The embodiment of the present application also provides a feeding device, including a feeding mechanism for the material 90 as above, and also including a shifting mechanism 70 and a mounting frame 80, the mounting frame 80 is provided with a socket 81, the feeding piece 10 is provided with an end of the air inlet 111 which can be detachably inserted into the socket 81, the material shifting assembly 20 is arranged on the mounting frame 80, and the shifting mechanism 70 is used to drive the mounting frame 80 to switch between the feeding position and the material taking position.
[0054] The shift mechanism 70 may include a motor and a guide rail, and the mounting frame 80 is arranged on the guide rail. The motor can drive the mounting frame 80 to translate along the guide rail, so as to switch between the loading position and the picking position. The loading position is the position where the stacked material 90 is manually transferred to the feeding member 10 using the loading string 30, and the picking position is the position where the transport mechanism picks up the material 90 from the feeding member 10.
[0055] The feeding device of the embodiment of the present application includes the feeding mechanism for the material 90 in any of the above-mentioned embodiments, and thus has the beneficial effects brought by the feeding mechanism for the material 90 in any of the above-mentioned embodiments, which will not be elaborated here.
[0056] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
