Not only this, it is also difficult for the current feeding mechanism to accurately secure the position of the microneedle original sheet, resulting in positional deviation for subsequent cutting and attaching.

Therefore, there is a need to develop a feeding system for soft medical beauty products such as microneedle base sheets, silica gel sheets, facial masks and the like, which can ensure the smoothness and position accuracy of sheet-shaped material pieces during feeding and provide guarantee for subsequent product processing.

In which both the sheet material 100 and the sheet material carrier 200 of fig. 1 are shown in a transparent manner for the convenience of explanation.

Referring to fig. 1 to 3, an embodiment of the present invention provides a feeding system, which is used for realizing automatic feeding of sheet-shaped material pieces 100, so as to automatically transfer and accurately position the sheet-shaped material pieces 100 at a discharging station. At the emptying station, the sheet material 100 can be automatically joined to the carrier 200, and the carrier 200 supports the sheet material 100 to perform subsequent processing procedures, such as cutting, attaching and the like. Herein, the sheet stock 100 may be a microneedle stock sheet, which is not limited to use in making eye masks, but may also be a patch for other functions.

Specifically, the feeding system comprises a feeding device 1, a discharging device 2 and a sheet taking device 3. The feeding system is provided with a loading station, a piece taking station and a discharging station.

The charging device 1 comprises at least one charging platform for loading the sheet elements 100. For efficiency, it is preferable that the loading platform is plural. As in some embodiments, the loading platforms comprise two loading platforms, a first loading platform 11 and a second loading platform 12, respectively, which are distributed at 180 °, the first loading platform 11 and the second loading platform 12 being generally identical in structure. As in other embodiments, the loading platforms comprise more than two loading platforms, such as three, four or more, all loading platforms being distributed over 360 °.

The loading device 1 further comprises a loading driving mechanism 13 connected with the loading platform to drive the loading platform to rotate horizontally or move horizontally so as to drive the loading platform to rotate or move from the loading station to the piece taking station, preferably, the loading driving mechanism 13 drives the loading platform to rotate horizontally, and more preferably, a plurality of loading platforms are distributed symmetrically or asymmetrically around a rotating axis.

In the following description, although two loading platforms distributed at 180 ° are taken as an illustration, the present invention is not limited thereto, and one skilled in the art should understand that the number of the loading platforms may be one or more than two.

When the loading platform is multiple, the loading device 1 further comprises a transfer platform 14 connected with the loading driving mechanism 13. The first loading platform 11 and the second loading platform 12 are distributed 180 ° around the transfer platform 14. Alternatively, the number of the loading platforms exceeds two, and all the loading platforms are distributed around the transfer platform 14 in 360 degrees, so that the loading efficiency is higher. The loading driving mechanism 13 is used for driving the adapter platform 14 to horizontally rotate around the axis of the adapter platform 14, so that the first loading platform 11 and the second loading platform 12 are driven to horizontally rotate around the adapter platform 14, and the switching of each loading platform between the loading station and the piece taking station can be realized.

For example, after the sheet material 100 is placed on the first loading platform 11, the loading driving mechanism 13 drives the transfer platform 14 to rotate horizontally by 180 °, so that the second loading platform 12 rotates from the original sheet taking station to the current loading station to prepare for loading, and simultaneously the first loading platform 11 rotates from the original loading station to the current sheet taking station to prepare for taking material. At the loading station, the sheet material 100 is placed manually, mainly by hand, on the first loading platform 11 or on the second loading platform 12. At the picking station, the sheet material 100 on the first loading platform 11 or the second loading platform 12 is picked by the picking device 3.

The advantage of providing two or more loading platforms is that on the one hand a continuous loading of sheet material pieces 100 is achieved, the loading waiting time is reduced, the loading efficiency is improved, and on the other hand it is convenient to provide a manual work area and a mechanical work area to ensure the safety of manual operation. Therefore, the feeding system is provided with a manual operation area and a mechanical operation area; the loading station is arranged in a manual operation area, and the taking station is arranged in a mechanical operation area; the loading station is close to the operator, and the piece taking station is far away from the operator, so that the operation safety is improved.

The sheet taking device 3 is arranged above the charging device 1 and the discharging device 2. The sheet taking device 3 comprises a suction cup 31 and further comprises a sheet taking driving mechanism 32, wherein the suction cup 31 is connected with the sheet taking driving mechanism 32. The suction cup 31 is used for vacuum adsorption of the sheet-shaped material piece 100, and the sheet taking driving mechanism 32 is used for driving the suction cup 31 to move. After the suction cups 31 move to the sheet taking station, the suction cups 31 take the sheet-shaped material 100 from the first loading platform 11 or the second loading platform 12, and then the sheet-shaped material is transferred from the sheet taking station to the discharging station, so that the sheet-shaped material 100 is automatically released on the discharging device 2.

The discharging device 2 comprises a discharging platform 21, and the discharging platform 21 is arranged on one side of the charging platform and is far away from the manual operation area. The emptying platform 21 provides an emptying station. After the suction cups 31 take the sheet-like material 100 on the loading platform and move to the discharging station, the suction cups 31 release the sheet-like material 100 to the discharging platform 21, and during the releasing process, the sheet-like material 100 can be accurately aligned and jointed with the carrier 200. The engagement of the sheet member 100 with the carrier 200 means that the sheet member 100 is disposed on the carrier 200, and the sheet member 100 is dragged by the carrier 200 to move, but the sheet member 100 does not fall off the carrier 200. For example, the carrier 200 is selected from a low viscosity film, and the carrier 200 is moved by a roller. It will be appreciated that the carrier 200 has been accurately positioned at the drop station and the take-off device 3 can accurately release the sheet 100 on the drop platform 21 to achieve accurate alignment of the sheet 100 with the carrier 200 for engagement.

In practice, the loading platform is used for vacuum-absorbing the sheet-shaped material piece 100, and the loading platform can generally provide vacuum pressure of-70 kPa to-20 kPa. Fig. 1 shows the sheet material 100 in a state of being vacuum-sucked to the first loading platform 11. Since the first and

second loading platforms

11 and 12 are identical in structure, only the first loading platform 11 will be described below, and the structure of the second loading platform 12 can be referred to the first loading platform 11.

The first loading platform 11 is provided with a plurality of air suction holes 111, and the distribution mode and the number of the air suction holes 111 are set according to actual needs. At the loading station, after the sheet material 100 is manually placed on the first loading platform 11, for example, the first loading platform 11 starts vacuum adsorption, that is, the sheet material 100 is vacuum-adsorbed and fixed on the first loading platform 11. The suction holes 111 may be various shapes, but are generally circular suction holes 111. The diameter of the suction hole 111 may be 2 to 4 mm.

However, in the actual charging process, the sheet-shaped material 100 is soft (such as soluble microneedle original sheet, mask, silicone sheet, etc.) and is a sheet material, which is very easy to curl and wrinkle, and if the sheet-shaped material 100 is manually flattened, the efficiency is very low, the operation is inconvenient, and the flattening effect is not good. Therefore, the feeding system is also provided with a flatness adjusting device, and the flatness adjusting device limits the shape of the sheet-shaped material 100 so that the sheet-shaped material 100 is adsorbed on the loading platform in a straight state in a vacuum manner, so that manual flattening operation is omitted, the efficiency is improved, and the flatness is effectively improved.

The specific structure of the flatness adjusting device is not limited in this application, and includes but is not limited to the following exemplified grooves, suction holes, and for example, blowing or pressing may also be used.

According to a preferred embodiment of the present invention, the flatness adjusting means includes a groove 112 provided on the charging platform, the shape of the groove 112 matches the shape of the sheet member 100, and a suction hole 111 is provided on the bottom wall of the groove 112. Optionally, the depth of the groove 112 is 4-6 mm, preferably 5-6 mm, so as to ensure a sufficient limiting depth. The sheet material 100 is disposed directly in the groove 112. Through the shape fit of the groove 112 and the sheet material 100, the problem of curling or folding of the sheet material 100 can be effectively avoided, and the position of the sheet material 100 can be accurately positioned, and meanwhile, the structure is simple and easy to realize, so that the feeding efficiency is improved, the feeding operation is simplified, and the flatness of the sheet material 100 during feeding is finally improved.

According to another preferred embodiment of the present invention, the flatness adjusting means includes a plurality of suction holes 111 on the loading platform. As shown in fig. 4a and 4b, the plurality of suction holes 111 form a central suction area 113 and an edge suction area 114 on the loading platform. For ease of illustration, the location of each adsorption zone is indicated generally by the dashed box in fig. 4a and 4 b. Wherein the edge suction region 114 provides a vacuum suction force greater than that of the center suction region 113, the edge suction region 114 serves to vacuum-suck the edge portion (the edge portion being a blank region) of the sheet-like member 100, and the center suction region 113 serves to vacuum-suck the middle portion of the sheet-like member 100. It should be understood that the central suction area 113 is not narrowly construed as an absolute intermediate position, and similarly, the intermediate portion of the sheet material member 100 is not narrowly construed as an absolute intermediate position. The edge suction areas 114 are at least two and are oppositely disposed, and two oppositely disposed edge suction areas 114 are shown in fig. 4 a. In other embodiments, the number of edge suction zones 114 may also be four, as shown in FIG. 4 b.

In some embodiments, the distribution density of the suction holes 111 of the edge suction region 114 is greater than that of the central suction region 113, and in this case, the size and shape of the suction holes 111 are generally the same, as shown in fig. 4a and 4 b.

In some embodiments, the suction holes 111 of the edge suction region 114 are larger in size than the suction holes 111 of the center suction region 113. The size of the air suction holes 111 is larger, and the adsorption capacity is stronger. At this time, the shapes of the suction holes 111 of the edge suction region 114 and the suction holes 111 of the center suction region 113 may be the same or different, and preferably, are the same. Optionally, the aperture of the air suction hole 111 of the edge adsorption area 114 is 3-4 mm, and the aperture of the air suction hole 111 of the central adsorption area 113 is 2-3 mm.

In other embodiments, a plurality of independent vacuum chambers that are not communicated are disposed inside the suction cup 31, and the central suction region 113 and the edge suction region 114 are respectively communicated with a corresponding one of the vacuum chambers.
