[0044] See also Figures 1 to 6 As shown, according to an embodiment of the utility model, a microneedle film feeding device is provided, comprising:

[0045] The tray trolley 11 comprises a plurality of upper and lower parallel and spaced brackets 111 and a microneedle tray 112 on the top surface of the bracket 111, each drug film cavity 1122 on the microneedle tray 112 is equipped with a microneedle drug film (not shown or labeled in the figure), and the microneedles of the microneedle drug film face the bottom wall of the drug film cavity 1122. It can be understood that the aforementioned microneedle tray 112 can be placed on the top surface of each layer of the bracket 111, so that the tray trolley 11 can transport more microneedle trays 112 at one time;

[0046] The tray positioning platform 12 is arranged adjacent to the tray trolley 11, and has a tray positioning area on its top surface, that is, the microneedle tray 112 transferred from the bracket 111 is positioned in the aforementioned tray positioning area, and then the microneedle drug film in the microneedle tray 112 can be taken out from the drug film cavity 1122 under the operation of subsequent corresponding equipment (such as a manipulator with a suction cup);

[0047] The tray transfer component 13 is disposed adjacent to the tray positioning platform 12 , and the tray transfer component 13 can transfer the microneedle tray 112 between the bracket 111 and the tray positioning area.

[0048] In this technical solution, each microneedle drug film prepared in the upstream process is carried on each microneedle tray 112 and transported to the target area by the pallet trolley 11, and the pallet transfer component 13 sequentially transfers each microneedle tray 112 on the pallet trolley 11 and places it in the pallet positioning area of ​​the pallet positioning platform 12, thereby realizing the automated transfer and loading of the microneedle tray 112, improving the automated production efficiency of the microneedle drug film, and meeting the subsequent automated packaging requirements of the microneedle drug film.

[0049] In some embodiments, the microneedle film loading device also includes: a trolley positioning jaw 14, including a first positioning jaw 141 and a second positioning jaw 142 arranged opposite to each other, and a transverse driving member 143 is provided between the first positioning jaw 141 and the second positioning jaw 142, and the transverse driving member 143 can drive the first positioning jaw 141 and the second positioning jaw 142 to move closer or farther.

[0050] In this technical solution, the position of the pallet trolley 11 between the two positioning jaws is locked by moving the first positioning jaw 141 and the second positioning jaw 142 of the trolley positioning jaw 14 toward or away from each other, thereby ensuring that the position of the pallet trolley 11 is at the same position each time, simplifying the movement control of the pallet transfer component 13.

[0051] As a specific embodiment, the pallet trolley 11 has a bottom plate 113, and two positioning blocks 115 arranged at a relative interval are arranged on the top surface of the bottom plate 113. Corresponding rollers can be arranged on the bottom surface to facilitate the movement of the position of the pallet trolley 11. There is a positioning concave-convex structure between the vertical surfaces of the positioning blocks 115 facing each other and the clamping surfaces of the first positioning clamping jaw 141 and the second positioning clamping jaw 142. The aforementioned positioning concave-convex structure can be, for example, a convex column arranged on the clamping surface of the positioning clamping jaw and a concave hole (such as Figure 3 As shown in FIG. 1 , the size of the protrusion matches the size of the concave hole, and when in the clamping state, the protrusion is accommodated in the concave hole. The above positioning concave-convex structure can ensure that the position of the pallet trolley 11 is reliable and stable.

[0052] In some embodiments, the top surface of the bottom plate 113 is further provided with vertical columns 114 arranged relatively spaced apart, each of the brackets 111 is connected to the spaced area between two adjacent vertical columns 114, and the top surface of each bracket 111 is provided with a stop column 1111 at its outer peripheral edge, and each of the stop columns 1111 together forms a placement area for the microneedle tray 112, see for details Figure 6 shown.

[0053] In this technical solution, by arranging a plurality of stop posts 1111 spaced apart at the outer edge of the bracket 111 , it is possible to ensure that the microneedle tray 112 is securely placed on the bracket 111 , thereby preventing the risk of the microneedle tray 112 detaching and falling during transportation.

[0054] As a specific embodiment of the tray transfer component 13, the tray transfer component 13 includes a first material picking jaw 131 and a second material picking jaw 132 that are relatively spaced apart, the microneedle tray 112 includes a tray body and supporting ears 1121 located on both sides of the width of the tray body, and the top surfaces of the first material picking jaw 131 and the second material picking jaw 132 are respectively formed with supporting grooves (not marked in the figure) for accommodating each of the supporting ears 1121, and the first material picking jaw 131 and the second material picking jaw 132 can be driven to rise and fall synchronously or to move synchronously between the tray positioning platform 12 and the tray trolley 11. Specifically, the first material picking jaw 131 and the second material picking jaw 132 are respectively located on the left and right sides of the tray positioning platform 12 (with the first and second material picking jaws 131 and 132 being located on the left and right sides of the tray positioning platform 12). Figure 1The orientation shown is for reference). When it is necessary to pick up materials from the tray trolley 11, the two material picking clamps are controlled to move synchronously in a straight line close to the tray trolley 11, and the position height is adjusted with the target microneedle tray 112. When the supporting ear 1121 is in the supporting groove, the two material picking clamps are controlled to rise a certain distance (higher than the height of the stop column 1111) to disengage the microneedle tray 112 from the placement area surrounded by the stop columns 1111, and then the two material picking clamps are controlled to move synchronously away from the tray trolley 11 to above the tray placement area, and then they are controlled to descend so that the microneedle tray 112 is placed on the tray placement area, and the two material picking clamps are controlled to move away to release the clamping of the microneedle tray 112. The aforementioned lifting and linear translation can be achieved by using a combination of transverse screw modules.

[0055] See Figure 5 As shown, in some embodiments, the bracket 111 has a first supporting area (not marked in the figure) and a second supporting area (not marked in the figure), the first supporting area is between the second supporting area and the pallet positioning platform 12, and the straight line direction passing through the two supporting ears 1121 at the same time is defined as the width direction of the bracket 111, the width of the first supporting area is not greater than the width of the pallet body, the width of the second supporting area is not less than the width between the two supporting ears 1121, and the supporting ears 1121 are in the first supporting area. Since the width of the first supporting area is not greater than the width of the pallet body, the first material picking clamp 131 and the second material picking clamp 132 can be moved in a straight line to form a cooperative positioning with the supporting ears 1121.

[0056] In a preferred embodiment, a tray position correction structure (not marked in the figure) is also provided on the tray positioning platform 12, and the tray position correction structure is used to position the microneedle tray 112 transferred by the tray transfer component 13 within the tray positioning area, so as to accurately position the microneedle tray 112 within the tray positioning area, which is beneficial for the accurate alignment of the suction cup of the subsequent transfer equipment with each microneedle film in the microneedle tray 112.

[0057] See Figure 2 As shown, in some embodiments, the tray position correction structure includes a first direction correction component and a second direction correction component, wherein the first direction correction component includes a front limit block 121 and a rear limit block 122 spaced apart along the first direction, and the spacing between the front limit block 121 and the rear limit block 122 can be controlled and adjusted; the second direction correction component includes a left limit block 123 and a right limit block 124 spaced apart along the second direction, and the spacing between the left limit block 123 and the right limit block 124 can be controlled and adjusted, the first direction is perpendicular to the second direction and both are in the horizontal plane, refer to Figure 2 In the orientation shown, the aforementioned first direction is also the left-right direction, and the second direction is also the inside-outside direction.

[0058] In this technical solution, before the microneedle tray 112 is placed in the aforementioned tray positioning area, the first direction correction component and the second direction correction component are both outside the tray positioning area. After the microneedle tray 112 is placed in the tray positioning area, the aforementioned correction component is controlled to move closer along the corresponding correction direction, so that the microneedle tray 112 can be accurately positioned at the preset position, ensuring the smooth subsequent detachment of the drug film.

[0059] In some embodiments, the front limit block 121 and the rear limit block 122 each have two spaced apart along the second direction, and the two front limit blocks 121 are both fixed on the top surface of the pallet positioning platform 12, and the two rear limit blocks 122 can be arranged on the top surface of the pallet positioning platform 12 for linear movement along the first direction, and the two rear limit blocks 122 are both cylindrical.

[0060] In this technical solution, by designing the rear limit block 122 as a movable cylinder, it can be ensured that when the microneedle tray 112 is positioned in the first direction, the cylinder and the edge of one side of the microneedle tray 112 form two-point contact, thereby eliminating the need to ensure the straightness of the processing, thereby reducing the difficulty of processing.

[0061] The left limit block 123 and the right limit block 124 each have two spaced apart along the first direction, the two left limit blocks 123 are respectively located on both sides of the supporting ear 1121 on one side of the tray body, and the two right limit blocks 124 are respectively located on both sides of the supporting ear 1121 on the other side of the tray body. In a specific embodiment, the two left limit blocks 123 and the two right limit blocks 124 are respectively arranged one by one opposite to each other, thereby realizing accurate automatic positioning of the left and right sides of the tray body.

[0062] In some embodiments, a plurality of vacuum adsorption holes 125 are provided in the positioning area of ​​the tray, and the positions of the vacuum adsorption holes 125 correspond one-to-one to the positions of the drug film cavities 1122 of the microneedle tray 112. When the microneedle drug film is taken out from the drug film cavities 1122 of the microneedle tray 112, the vacuum adsorption holes 125 are controlled to generate vacuum adsorption force to prevent the silicone mold in the drug film cavity 1122 from being taken out synchronously with the microneedle drug film.

[0063] The tray positioning platform 12 is also provided with a tray pressing member 126, which has a tray picking position outside the tray positioning area and an adsorption sealing position within the tray positioning area and capable of applying downward pressure to the microneedle tray 112 in the tray positioning area. The tray pressing member 126 can be driven to switch between the tray picking position and the adsorption sealing position. When the microneedle tray 112 is placed in the tray positioning area, the tray pressing member 126 is controlled to press down the edge of the microneedle tray 112. Position, on the one hand, can further ensure the reliable and stable position of the microneedle tray 112, prevent it from moving in the height direction following the removal of the microneedle medicine film, on the other hand, can improve the sealing of the bottom surface of the microneedle tray 112 to the openings of each vacuum adsorption hole 125, thereby improving the adsorption effect of the silicone mold in the medicine film cavity 1122. In a preferred embodiment, a silicone film (not shown in the figure) is provided around the opening of each vacuum adsorption hole 125, which can further improve the sealing effect of the bottom surface of the microneedle tray 112 to the opening of each vacuum adsorption hole 125.

[0064] It can be understood that the lateral movement (approaching or moving away) of the first direction correction assembly and the second direction correction assembly, and the lifting and deflection movement of the tray pressing member 126 are all realized by corresponding driving members, such as a combination of lifting screws and deflection motors, and these driving members are preferably integrated into the tray positioning platform 12. The aforementioned vacuum adsorption hole 125 is controllably connected to the corresponding vacuum generating device, and the aforementioned vacuum generating device can be, for example, a vacuum pump, and the vacuum pump can also be integrated into the tray positioning platform 12.

[0065] It is easy for those skilled in the art to understand that, without conflict, the advantageous technical features of the above-mentioned methods can be freely combined and superimposed.

[0066] The above is only a preferred embodiment of the utility model, and is not intended to limit the utility model. Any modifications, equivalent replacements and improvements made within the spirit and principles of the utility model should be included in the protection scope of the utility model. The above is only a preferred implementation of the utility model. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the utility model, and these improvements and variations should also be regarded as the protection scope of the utility model.
