[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0034] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0036] In the description of this embodiment, the terms "upper", "lower", "right", etc., directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0037] In this embodiment, a feeding device is provided, which includes a moving mechanism and an adsorption device. The adsorption device is connected to the moving mechanism, and the moving mechanism can drive the adsorption device to move along a preset path to complete the adsorption and transportation of the workpiece. By adsorbing and transporting the workpiece by the adsorption device, damage to the workpiece can be effectively avoided. However, the problem that immediately arises is that when adsorbing a larger workpiece, the adsorption force may be insufficient, causing the workpiece to fall. If the adsorption device corresponding to the size is replaced before transportation, the feeding efficiency will be reduced.

[0038] To solve the above technical problems, Figure 1 and Figure 2 As shown, this embodiment also provides an adsorption device, which includes a main pipe 10 and a connecting assembly 20. The main pipe 10 is penetrated by a first pipeline 11 and a second pipeline 12 along its axial direction, and the first pipeline 11 and the second pipeline 12 are not connected to each other; the connecting assembly 20 is arranged at one end of the main pipe 10, and the connecting assembly 20 includes a first connecting member 21 and a second connecting member 22. The first connecting member 21 is connected to the first pipeline 11, and the second connecting member 22 is connected to the second pipeline 12. The end of the connecting assembly 20 away from the main pipe 10 is used to be connected to the negative pressure generator, so that the negative pressure effect can be transmitted to the end of the main pipe 10 away from the connecting assembly 20 through the first pipeline 11 and / or the second pipeline 12 and adsorb the workpiece.

[0039] When adsorbing a workpiece of a certain size, the first connector 21 or the second connector 22 can be opened first to form a negative pressure effect in the first pipeline 11 or the second pipeline 12, adsorb the workpiece, and move the workpiece through the moving mechanism; when encountering a workpiece of a larger size, the first connector 21 and the second connector 22 can be opened at the same time, and the first pipeline 11 and the second pipeline 12 can simultaneously generate a negative pressure effect, thereby generating a sufficiently large adsorption force to transport the larger workpiece. In this process, there is no need to replace the adsorption device, and it is only necessary to open or close the first connector 21 or the second connector 22 according to actual needs. The operation is simple and convenient and does not reduce the transportation efficiency.

[0040] It should be noted here that the first connector 21 and the second connector 22 are both gas circuit connectors, which are convenient for connecting with the negative pressure generator and are easy to install. In addition, the device is provided with a through hole 13 along the axial direction. When the end of the main pipe 10 adsorbs and transports the workpiece to the preset station, after closing the gas circuit connector, both sides of the workpiece are at atmospheric pressure, which makes it easier to fall, thereby improving the feeding efficiency. It is further noted that in this embodiment, the workpiece is a gasket of different specifications. In other embodiments, this device can also be used to adsorb different workpieces, and the scope of use of the adsorption device is not limited in this embodiment.

[0041] In order to ensure a good adsorption effect, the main pipe 10 is provided with a first annular cavity and a second annular cavity along the axial direction, the first annular cavity can form a first pipeline 11, and the second annular cavity can form a second pipeline 12. In this structure, a negative pressure effect can be generated in both the first annular cavity and the second annular cavity, so that an annular adsorption effect can be formed on the end face of the main pipe 10. Compared with a straight pipe structure, this method has a better adsorption effect, can make the workpiece more evenly stressed, and thus ensure that it will not fall during the loading process.

[0042] like Figure 1 As shown, the inner diameters of the first pipeline 11 and the second pipeline 12 are different. This structure enables the first pipeline 11 and the second pipeline 12 to produce different negative pressure effects, thereby further expanding the scope of use. Specifically, as Figure 2As shown, the inner diameter of the second pipeline 12 is smaller than that of the first pipeline 11. Under the premise of the same flow rate, the smaller the diameter, the higher the flow velocity of the fluid. Therefore, the air flow velocity in the first pipeline 11 is smaller than that in the second pipeline 12. Further, according to the Bernoulli principle, the pressure generated at the port of the first pipeline 11 is smaller than the pressure generated at the port of the second pipeline 12. Therefore, the smaller the diameter, the better the negative pressure effect. That is, the second pipeline 12 can adsorb larger workpieces than the first pipeline 11. According to this feature, for small-sized workpieces, the first connector 21 can be opened for adsorption alone; for medium-sized workpieces, the second connector 22 can be opened for adsorption alone; for large-sized workpieces, the first connector 21 and the second connector 22 can be opened at the same time for adsorption, thereby further improving adjustability.

[0043] like Figure 1 and Figure 2 As shown, the adsorption device further includes a suction head 30, which is arranged at one end of the main pipe 10 away from the connecting assembly 20. The diameter of the suction head 30 is larger than the diameter of the main pipe 10, and is connected to both the first pipe 11 and the second pipe 12. This arrangement enables the negative pressure effect of the first pipe 11 and the second pipe 12 to be transmitted to the suction head 30, and forms a negative pressure at the end face of the suction head 30. Since the diameter of the suction head 30 is larger than the diameter of the main pipe 10, the contact area with the workpiece is increased, thereby ensuring a better adsorption effect and a better force effect on the workpiece, thereby efficiently feeding the material.

[0044] It is worth noting that, in the present embodiment, a first adsorption hole 31 and a second adsorption hole 32 are provided inside the suction head 30, wherein the first adsorption hole 31 is connected to the first pipeline 11, and the second adsorption hole 32 is connected to the second pipeline 12, and the first adsorption hole 31 and the second adsorption hole 32 are both connected to the end face of the suction head 30, so that a negative pressure effect can be formed on the end face of the suction head 30 through the first adsorption hole 31 and the second adsorption hole 32, thereby completing the adsorption work of the workpiece (gasket).

[0045] To ensure good airtightness, Figure 2As shown, the suction head 30 is sleeved on the outer periphery of the main pipe 10, and a first sealing member 40 is provided between the suction head 30 and the main pipe 10. This method is not only easy to install, but also convenient to use. The first sealing member 40 provided between the suction head 30 and the main pipe 10 can also effectively avoid air leakage between the main pipe 10 and the suction head 30, thereby ensuring good adsorption. In addition, a second sealing member 60 is provided at the connection between the first adsorption hole 31 and the first pipeline 11, and the second adsorption hole 32 and the second pipeline 12, thereby avoiding air leakage at the gap between the first adsorption hole 31 and the first pipeline 11, and the second adsorption hole 32 and the second pipeline 12, thereby ensuring a good adsorption effect. It should be noted here that, in this embodiment, the first sealing member 40 is a sealing ring, and the second sealing member 60 is a sealing gasket. The sealing ring and the sealing gasket have a simple structure, low price, and high sealing effect.

[0046] In addition, if Figure 1 and Figure 2 As shown, the adsorption device also includes an end cap 50, which is detachably arranged at one end of the main pipe 10 near the connecting assembly 20, the first pipeline 11 is arranged on the inner periphery of the second pipeline 12, and the first pipeline 11 is connected to the end cap 50, and the first connector 21 is arranged on the end cap 50. This arrangement is not only convenient for the arrangement and arrangement of the first pipeline 11 and the second pipeline 12, but also can effectively avoid interference with the second pipeline 12 when the first connector 21 is arranged, and the first connector 21 can be directly arranged and connected to the end cap 50, thereby reducing the processing difficulty and processing cost. At the same time, since the end cap 50 and the main pipe 10 are detachably connected, it is convenient to repair and replace the first connector 21.

[0047] like Figure 2 As shown, in order to ensure good sealing, a second sealing member 60 is provided between the end cap 50 and the main pipe 10. The second sealing member 60 can ensure the airtightness of the connection between the end cap 50 and the main pipe 10, thereby avoiding air leakage, and further ensuring that a good negative pressure effect can be formed in the first pipeline 11. It should be noted here that in this embodiment, the second sealing member 60 is a sealing gasket.

[0048] To further simplify the overall structure, Figure 1 and Figure 2 As shown, the adsorption device also includes a mounting frame 70, which is detachably connected to the outer periphery of the main pipe 10, and the second pipeline 12 is connected to the mounting frame 70, and the second connecting member 22 is arranged on the mounting frame 70. In this structure, the second connecting member 22 can be directly arranged on the mounting frame 70, thereby simplifying the connection structure between the second connecting member 22 and the main pipe 10, and the detachable connection method can also facilitate subsequent maintenance and replacement. In addition, a plurality of mounting holes 71 are arranged on the mounting frame 70, and the device can be directly mounted on the mobile mechanism using bolts, screws and other structures, thereby improving the convenience of use.

[0049] In addition, if Figure 2 As shown, a first seal 40 (sealing ring) is provided between the mounting frame 70 and the main pipe 10. By providing the first seal 40, air leakage at the connection between the inner periphery of the mounting frame 70 and the outer periphery of the main pipe 10 can be avoided, thereby ensuring that a good negative pressure effect can be formed in the second pipeline 12, thereby ensuring the stability of the adsorption process.

For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention.
