Description
Technical Field
[0001] The invention belongs to the technical field of punching and cutting all-in-one machines, and relates to a punching and blanking structure of a microneedle patch punching and cutting roller cutting, tearing, wasting and pasting all-in-one machine. Background Art
[0002] like Figure 1 As shown, the microneedle patch is punched out from a soluble microneedle original sheet. During the punching process, a larger soluble microneedle original sheet is usually cut into corresponding shapes multiple times to form a soluble microneedle sheet 1 that can be absorbed. At the same time, the composite film 2 is roller-cut. After the cutting, the composite film 2 is connected with an adhesive sheet 3 of the corresponding shape. The inner edge of the adhesive sheet 3 has an inner adhesive surface 31. The punching station cuts the soluble microneedle original sheet 4. After the cutting, the soluble microneedle original sheet 4 forms multiple groups of soluble microneedle sheets 1. The robot places the cut soluble microneedle sheet 1 on the adhesive sheet 3. The soluble microneedle sheet 1 is bonded to the exposed inner adhesive surface 31 on the inner edge of the adhesive sheet 3 to form a microneedle patch.
[0003] Existing punching and cutting roller cutting, tearing and pasting all-in-one machines, such as Chinese patent application [application publication number: CN119550431A] discloses a punching and cutting roller cutting, tearing and pasting all-in-one machine for microneedle patches, including a frame, a cutting roller knife seat is provided on the frame, a bottom roller and a cutting roller are rotatably connected to the cutting roller knife seat, a space between the bottom roller and the cutting roller can allow a composite film to pass through and cut it, the cutting roller has multiple groups of roller blade groups arranged along the circumference of the cutting roller and multiple pairs of connecting roller knives arranged along the circumference of the cutting roller, each group of roller blade groups includes waist-shaped roller blade 1, roller blade 2 and roller blade 3, the roller blade 1 of the same group is located in the inner circle of roller blade 2, the roller blade 2 of the same group is located in the inner circle of roller blade 3, and both ends of the roller blade 2 are An opening is opened, and the two end ends of the connecting roller knife connect the opening walls of roller blade two in the two adjacent roller blade groups. The middle part of the connecting roller knife intersects with the corresponding roller blade three. Roller blade three has a reserved notch on the blade at the intersection with the connecting roller knife. The edge height of roller blade two is lower than the edge height of roller blade one and roller blade three. A truss robot that can grab and move the soluble microneedle sheet to the waist-shaped sheet is connected to the frame. The front and rear ends of the soluble microneedle sheet pasting unloading table are fixedly connected with support rollers that can horizontally tension the cut composite film. The soluble microneedle sheet pasting unloading table is also hinged with a unloading tray that can absorb the waist-shaped sheet. The truss robot can push the soluble microneedle sheet to drive the waist-shaped sheet to move downward until it is pressed on the unloading tray.
[0004] The soluble microneedle sheet in the above structure is grabbed by a truss robot, and after being grabbed, it is moved by the truss robot to the composite film cut on the soluble microneedle sheet pasting unloading table. The composite film is tensioned by a tensioning roller, and the truss robot presses the composite film on the unloading tray and moves synchronously with the unloading tray to realize the demolding of the microneedle patch pasted on the composite film. However, since the composite film is only tensioned by the tensioning roller, the tensioning effect of the composite film on the unloading tray is poor during the gradual downward movement, making it difficult to pull the microneedle patch out of the composite film, resulting in some microneedle patches unable to detach from the composite film, thereby affecting the yield of the molded product, reducing production efficiency and unloading efficiency, and when moving downward, the composite film is prone to displacement deviation during the continuous pulling process, reducing the yield of the microneedle patch. Summary of the Invention
[0005] The purpose of the present invention is to address the above-mentioned problems in the existing technology and propose a punching and blanking structure of a microneedle patch punching roller cutting, tearing, and pasting all-in-one machine. The technical problem to be solved by the present invention is: how to solve the problem of low yield of existing microneedle patch processing equipment when processing smaller microneedle patches for a long time.
[0006] The purpose of the present invention can be achieved through the following technical solutions:
[0007] A punching and blanking structure of a microneedle patch punching and roller cutting and tearing and pasting all-in-one machine, the microneedle patch punching and roller cutting and tearing and pasting all-in-one machine includes a frame, a cutting roller knife seat arranged on the frame and capable of roller cutting a composite film, and a soluble microneedle sheet pasting and blanking platform arranged on the frame and located behind the cutting roller knife seat. The punching and blanking structure includes a truss manipulator that is slidably connected to the frame in the left and right directions and can transfer the soluble microneedle sheet to the composite film and press the composite film down onto the blanking tray. The truss manipulator is located on one side of the soluble microneedle sheet pasting and blanking platform. The soluble microneedle sheet pasting and blanking platform includes two support plates arranged opposite to each other in the left and right directions, and multiple support plates are connected to the support plates. The cam is connected to the support frame by a hinged shaft, and the upper end of the support frame is connected to the support frame by a hinged shaft. The upper end of the support frame is fixed with a plurality of positioning strips, and the lower end of the support frame is provided with positioning grooves corresponding to the positioning strips. The positioning strips are embedded in the corresponding positioning grooves and can slide relative to the groove walls of the positioning grooves. The top surface of the positioning strips is lower than the highest point of the tensioning roller and can be higher than the upper end surface of the unloading disc. The positioning strips are arranged at intervals in the front and rear directions. The truss manipulator has a downwardly protruding suction cup, and when the truss manipulator is pressed down, the suction cup can be embedded between two adjacent positioning strips.
[0008] During production, the composite film is first roll-cut by a cutting roller holder. The cutting roller holder is like the cutting roller holder in the comparative document mentioned above. The cutting of the composite film is achieved by the cooperation of the bottom roller and the cutting roller. The cut composite film is tensioned by the tensioning roller of the soluble microneedle sheet pasting unloading table, and then the cut soluble microneedle sheet is transferred to the cut composite film by the truss manipulator, and the composite film is pressed on the unloading disc. After pressing, the truss manipulator moves downward synchronously with the unloading disc, and moves to the positioning bar to disengage from the positioning groove. At this time, the soluble microneedle sheet is bonded to the adhesive sheet on the composite film and separated from the composite film, thereby realizing rapid unloading of the microneedle patch. The top surface of the positioning bar is set below the highest point of the tensioning roller, and the unloading disc gradually moves downward. When the positioning strip is moved, the top surface is higher than the upper end surface of the discharge tray, and the positioning strips are spaced apart in the front-to-back direction. The truss manipulator is provided with a downwardly protruding suction cup, which can adsorb the soluble microneedle sheet. When the truss manipulator is pressed down, the suction cup can be embedded between two adjacent positioning strips, so the positioning strip has the resistance to push the composite film upward, and the truss manipulator and the discharge tray have the thrust to push the composite film downward. With the mutual cooperation of the two, the microneedle patch bonded to the composite film can be quickly detached from the composite film, thereby facilitating the unloading of the microneedle patch. After the microneedle patch is detached from the composite film and placed on the discharge tray, the truss manipulator is moved upward, and the discharge tray rotates along with the hinge shaft, so that the microneedle patch can quickly slide out from the discharge tray to achieve unloading.
[0009] The present application is to provide a positioning strip. When the blanking tray moves downward, the positioning strip cooperates with the positioning groove on the blanking tray to guide the blanking tray, ensuring that the truss robot can stably stick the soluble microneedle sheet on the corresponding adhesive sheet. Since it takes time to compact it during the pasting process, in order to avoid displacement deviation during the compacting process, the positioning strip is used to ensure the stability of the blanking tray's up and down movement. In the process of gradual downward movement, although the tensioning roller is used to tension the composite film, the area of the composite film above the blanking tray is large, so the positioning strip can also provide resistance to prevent the composite film from moving downward, helping the microneedle patch to fall off the composite film, thereby ensuring the stability of the pasting and achieving rapid blanking, improving the convenience of blanking and demolding, and also improving the product yield.
[0010] One of the support plates is connected to a blanking rotary cylinder, and a motor shaft of the blanking rotary cylinder is fixedly connected to one end of the hinge shaft and drives the hinge shaft to rotate.
[0011] In the punching and blanking structure of the above-mentioned microneedle patch punching, roller cutting, tearing, and pasting integrated machine, the positioning strip is in the shape of a long strip, the width direction of the positioning strip is arranged vertically, and the outer side wall of the positioning strip can fit with the groove wall of the positioning groove.
[0012] The width direction of the positioning strip is arranged vertically to minimize the area of the upper end surface of the discharge tray occupied by the top surface of the positioning groove, thereby ensuring that the contact area between the composite film and the discharge tray is less affected, ensuring that the truss robot can stably press the composite film on the discharge tray, and ensuring fast and stable discharge of the microneedle patch.
[0013] In the punching and blanking structure of the above-mentioned microneedle patch punching, roller cutting, tearing, and pasting integrated machine, a blanking cylinder is connected to the middle of the hinge shaft, the piston rod of the blanking cylinder is fixedly connected to the front end of the blanking disk, and all positioning strips are located behind the hinge shaft.
[0014] By fixing the piston rod of the discharge cylinder to the front end of the discharge tray, and the positioning bar is arranged behind the hinge shaft, after the microneedle patch is separated from the composite film, the discharge tray rotates with the rotation of the hinge shaft, and the rear end of the discharge tray swings downward, that is, the discharge tray under the positioning bar will swing downward, thereby realizing the discharge of the microneedle patch. Therefore, the position of the positioning bar will not affect the discharge of the microneedle patch on the discharge tray, thereby ensuring stable discharge of the microneedle patch.
[0015] In the punching and blanking structure of the above-mentioned microneedle patch punching, roller cutting, tearing, waste and pasting all-in-one machine, the positioning strips are arranged parallel to each other, and the plurality of positioning strips are evenly distributed along the front-to-back direction.
[0016] Since the adhesive sheets on the cut composite film are arranged in multiple rows evenly distributed along the front-to-back direction, the positioning strips are parallel and evenly distributed along the front-to-back direction. When cutting the material, the adhesive sheets are blocked on the positioning strips and are located between two adjacent positioning strips, which ensures the accuracy of the adhesive bonding while improving the stability of the cutting.
[0017] In the punching and blanking structure of the above-mentioned microneedle patch punching, roller cutting, tearing, waste and pasting all-in-one machine, the upper end surface of the positioning strip is flush with the upper end surface of the support plate.
[0018] The setting of this structure does not affect the support of the composite film by the support roller, and after installation, the positioning strip can be stably limited by the support plate. If it is set in a protruding manner, scratches and the like will occur during installation. Moreover, since the positioning strip is only fixed on the support plate at both ends, when the composite film moves downward, the positioning strip is subjected to the downward pressure of the composite film. Therefore, the two ends of the positioning strip need to be stably set on the support plate to improve the stability of the blanking, thereby improving the yield of the microneedle patch.
[0019] In the punching and blanking structure of the above-mentioned microneedle patch punching roller cutting, tearing, and pasting integrated machine, a punching table located on one side of the soluble microneedle patch pasting and blanking table is fixed on the frame, and a rotating cylinder is connected to the truss manipulator, and a suction cup plate is fixed to the rotating axis of the rotating cylinder, and a plurality of pairs of the above-mentioned suction cups are provided on the suction cup plate, and the suction cups are eccentrically arranged relative to the rotation axis. The punching table has a bottom plate for placing the cut soluble microneedle original sheet and can slide out of the punching table along the left and right directions of the frame, and a plurality of groups of independently arranged air vents are provided on the bottom plate, and the truss manipulator can absorb the soluble microneedle sheet on one group of air holes through the suction cup and transfer it to the composite film stretched on the soluble microneedle sheet pasting and blanking table, and the other groups of air holes absorb the cut soluble microneedle original sheet on the bottom plate.
[0020] The punching table is provided with a cutter that can move in the up and down directions. The cutter is a prior art. The soluble microneedle original sheet is cut by the cutter to form multiple groups of soluble microneedle sheets. One group of soluble microneedle sheets on the bottom plate is sucked up by the suction cup through the truss manipulator. At this time, only the vent holes corresponding to the group of soluble microneedle sheets on the bottom plate are ventilated, while the other groups maintain vacuum adsorption, so that the suction cup can quickly and stably absorb the group of soluble microneedle sheets. After absorption, the truss manipulator is moved to place the group of soluble microneedle sheets on the composite film of the soluble pasting unloading table to achieve pasting. When it is necessary to absorb other groups of soluble microneedle sheets again, the truss manipulator can be moved left and right or the rotary cylinder can be driven to rotate the suction cup plate. The suction cup plate can grab other groups of soluble microneedle sheets on the bottom plate in turn and repeat the above actions. When grabbing, the bottom plate will ventilate the corresponding air holes and adsorb the soluble microneedle original sheets on the bottom plate through other air holes, so as to facilitate the stable grabbing of the corresponding soluble microneedle sheets and place them on the cut composite film. In this process, only the truss manipulator moves a small distance in the left and right directions or drives the rotary cylinder to rotate the suction cup plate 180 degrees to realize the absorption of soluble microneedle sheets in different positions. There is no need to adjust the relative positions of multiple groups of suction cups on the suction cup plate many times, which reduces the error accumulation, thereby ensuring the convenience of absorption and the accuracy of position, thereby improving the yield of microneedle patches during long-term processing.
[0021] The bottom plate and the rack are connected by slide rails and sliders.
[0022] In the punching and blanking structure of the above-mentioned microneedle patch punching roller cutting, tearing, and pasting machine, a rotating disk is connected to the rotating shaft of the rotating cylinder, the suction cup plate is fixed under the rotating disk, and the outer shell of the rotating cylinder protrudes downward to form a guide disk corresponding to the rotating disk. The upper end surface of the rotating disk is in contact with the lower end surface of the guide disk and can rotate relative to each other.
[0023] By coordinating the rotating disk and the guide disk, the stability of the suction cup plate driven by the rotating shaft is increased. By increasing the contact area of the rotation, the stability of the rotation is improved, thereby improving the accuracy of the position of the suction cup after rotation.
[0024] In the punching and blanking structure of the above-mentioned microneedle patch punching, roller cutting, tearing, scrapping and pasting all-in-one machine, the suction cup plate is provided with an air suction communication port corresponding to each pair of suction cups.
[0025] The setting of this structure allows the suction cup to suck the soluble microneedle sheet individually or the entire suction cup to suck the soluble microneedle sheet, which facilitates the suction of a pair of soluble microneedle sheets and improves the versatility of the truss manipulator.
[0026] In the punching and blanking structure of the above-mentioned microneedle patch punching, roller cutting, tearing, waste and pasting integrated machine, the lower end of the base plate is connected to a ventilation tube arranged in a one-to-one correspondence with the vent, and the length direction of the ventilation tube is arranged along the sliding direction of the base plate.
[0027] The setting of the ventilation pipe only requires opening a plurality of ventilation holes on the base plate, which makes the processing of the base plate convenient, and the setting of the ventilation pipe also facilitates maintenance and inspection in the subsequent long-term production process.
[0028] In the punching and unloading structure of the above-mentioned microneedle patch punching, roller cutting, tearing, and pasting all-in-one machine, a preliminary cutting station is provided on one side of the punching station, and a preliminary cutting knife fixed on the frame and used for preliminary cutting of the soluble microneedle original sheet and a preliminary cutting plate that can slide along the left and right directions of the frame are provided on the preliminary cutting station. The preliminary cutting plate is located below the preliminary cutting knife, and a material picking robot is connected to the frame along the horizontal sliding direction. A material picking cylinder is installed on the material picking robot, and a material picking plate is connected to the material picking shaft of the material picking cylinder. At least two suction discs that can absorb the cut soluble microneedle original sheet are provided on the material picking plate, and the suction discs are eccentrically arranged relative to the axis of the material picking shaft. The material picking robot can transfer the soluble microneedle original sheet cut on the preliminary cutting plate to the bottom plate.
[0029] Since the entire soluble microneedle original sheet is relatively large, a primary cutting table can be set up. The primary cutting knife can be a cross-shaped blade to cut the soluble microneedle original sheet on the primary cutting plate. The soluble microneedle original sheet is first cut into several large pieces, and then sucked up by the material picking plate and transferred to the punching table, realizing secondary punching, which is convenient for the rapid and continuous production and cutting of microneedle patches. It also adopts an eccentric design, and by driving the material picking cylinder to rotate, it can realize the grabbing of large pieces at different positions, thereby improving the convenience of grabbing.
[0030] The primary cut plate and the rack are connected by slide rails and sliders.
[0031] In the punching and blanking structure of the above-mentioned microneedle patch punching, roller cutting, tearing, waste and pasting integrated machine, the material taking plate is in a long strip shape, and one end of the material taking plate can be inserted into the punching table.
[0032] The arrangement of this structure makes it possible for the base of the punching table to not need to move toward the primary cutting table, and the soluble microneedle original sheet after the primary cutting can be moved and unloaded simply by rotating, which is easy to control.
[0033] Compared with the prior art, the present invention has the following advantages:
[0034] 1. By providing a positioning strip, when the blanking tray moves downward, the positioning strip cooperates with the positioning groove on the blanking tray to guide the blanking tray, ensuring that the truss manipulator can stably stick the soluble microneedle sheet on the corresponding adhesive sheet. Since it takes time to compact it during the pasting process, in order to avoid displacement deviation during the compaction process, the positioning strip is used to ensure the stability of the blanking tray's up and down movement. In the process of gradual downward movement, although the tensioning roller is used to tension the composite film, the area of the composite film above the blanking tray is large, so the positioning strip can also provide resistance to prevent the composite film from moving downward, helping the microneedle patch to fall off the composite film, thereby ensuring the stability of the pasting and achieving rapid blanking, improving the convenience of blanking and demoulding, and also improving the product yield.
[0035] 2. The truss manipulator moves a short distance in the left and right direction or drives the rotary cylinder to rotate the suction cup plate 180 degrees to absorb the soluble microneedle sheets at different positions. There is no need to adjust the relative positions of multiple groups of suction cups on the suction cup plate many times, which reduces the error accumulation and ensures the convenience of absorption and the accuracy of position, thereby improving the yield of microneedle patches during long-term processing.

[0050] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.
[0051] Example 1
[0052] like Figure 2 and Figure 5As shown, the punching and blanking structure of the microneedle patch punching and cutting roller cutting and tearing waste pasting integrated machine includes a frame 5, a cutting roller knife seat 6 set on the frame 5 and capable of rolling the composite film 2, and a soluble microneedle sheet pasting blanking table 7 set on the frame 5 and located behind the cutting roller knife seat 6. The punching and blanking structure includes a sliding connection on the frame 5 along the left and right directions and can transfer the soluble microneedle sheet 1 to the composite film 2 to transfer the composite film 2 to the composite film 2. The truss manipulator 8 is pressed down onto the blanking tray 72. The truss manipulator 8 is located on one side of the soluble microneedle sheet pasting blanking platform 7. The soluble microneedle sheet pasting blanking platform 7 includes two support plates 71 arranged opposite to each other in the left and right directions. The support plates 71 are connected to a plurality of tensioning rollers 75 that can tension the cut composite film 2. A hinge shaft 74 is rotatably connected between the two support plates 71, and the hinge shaft 74 is connected to the blanking tray 72 that can move up and down relative to the hinge shaft 74.
[0053] Specifically, if Figure 2 、 Figure 3 、 Figure 5 、 Figure 6 、 Figure 9 and Figure 12 As shown, a plurality of positioning bars 73 are fixedly connected to the upper end of the support plate 71, and a positioning groove 72a corresponding to the positioning bars 73 is opened on the unloading tray 72. The positioning bars 73 are embedded in the corresponding positioning groove 72a and can slide relative to the groove wall of the positioning groove 72a. The top surface of the positioning bar 73 is lower than the highest point of the tensioning roller 75 and can be higher than the upper end surface of the unloading tray 72. The positioning bars 73 are arranged at intervals in the front-to-back direction. The truss manipulator 8 has a downwardly protruding suction cup 83. When the truss manipulator 8 is pressed down, the suction cup 83 can be embedded between two adjacent positioning bars 73.
[0054] During production, the composite film 2 is first roll-cut by the cutting roller holder 6. The cutting roller holder 6 is like the cutting roller holder 6 in the comparative document mentioned above. It realizes cutting of the composite film 2 by the cooperation of the bottom roller and the cutting roller. The cut composite film 2 is tensioned by the tensioning roller 75 of the soluble microneedle sheet pasting unloading table 7, and then the cut soluble microneedle sheet 1 is transferred to the cut composite film 2 by the truss manipulator 8, and the composite film 2 is pressed on the unloading tray 72. After pressing, the truss manipulator 8 moves downward synchronously with the unloading tray 72, and moves to the positioning bar 73 to disengage from the positioning groove 72a. At this time, the soluble microneedle sheet 1 is bonded to the adhesive sheet 3 on the composite film 2 and separated from the composite film 2, so as to realize rapid unloading of the microneedle patch. By setting the top surface of the positioning bar 73 to be below the highest point of the tensioning roller 75, and when the unloading tray 72 gradually moves downward The top surface of the positioning bar 73 is higher than the upper end surface of the blanking tray 72, and the positioning bars 73 are spaced apart in the front-to-back direction. The truss manipulator 8 has a downwardly protruding suction cup 83, which can adsorb the soluble microneedle sheet 1. When the truss manipulator 8 is pressed down, the suction cup 83 can be embedded between two adjacent positioning bars 73, so the positioning bar 73 has the resistance to push the composite film 2 upward, and the truss manipulator 8 and the blanking tray 72 have the thrust to push the composite film 2 downward. With the mutual cooperation of the two, the microneedle patch bonded to the composite film 2 can be quickly detached from the composite film 2, thereby facilitating the unloading of the microneedle patch. After the microneedle patch is detached from the composite film 2 and placed on the blanking tray 72, the truss manipulator 8 is moved upward, and the blanking tray 72 rotates along with the hinge shaft 74, so that the microneedle patch can quickly slide out of the blanking tray 72 to achieve unloading.
[0055] The present application is to provide a positioning bar 73. When the blanking tray 72 moves downward, the positioning bar 73 cooperates with the positioning groove 72a on the blanking tray 72 to guide the blanking tray 72, ensuring that the truss robot 8 can stably stick the soluble microneedle sheet 1 on the corresponding adhesive sheet 3. Since it takes time to compact it during the pasting process, in order to avoid displacement deviation during the compacting process, the positioning bar 73 is used to ensure the stability of the blanking tray 72 moving up and down. In the process of gradual downward movement, although the tensioning roller 75 is used to tension the composite film 2, the area of the composite film 2 above the blanking tray 72 is large, so the positioning bar 73 can also provide resistance to prevent the composite film 2 from moving downward, helping the microneedle patch to fall off the composite film 2, thereby ensuring the stability of the pasting and achieving rapid blanking, improving the convenience of blanking and demolding, and also improving the product yield.
[0056] In the specific process of taking materials, the suction cup 83 of the truss manipulator 8 is located Figure 12 When the position of e is Figure 12 The two groups of soluble microneedle sheets 1, a and b, of the cut soluble microneedle original sheet 4 are grabbed in sequence;
[0057] The suction cup 83 of the truss manipulator 8 rotates 180 degrees and is located at Figure 12 When the position is at f, it can Figure 12 The c-group soluble microneedle sheet 1 of the cut soluble microneedle original sheet 4 is grasped, and after grasping, the suction cup 83 is rotated 180 degrees again and is located at Figure 12 At position e in the middle, place the soluble microneedle sheet 1 on the suction cup 83 on the composite film 2, and repeat the above steps to grasp the soluble microneedle sheet 1 of group d, so that the grasping of the truss manipulator 8 is more convenient and simple, and the parameters required to be adjusted are smaller, thereby improving its grasping accuracy. Moreover, no matter which group c or d is grasped, the suction cup 83 can be rotated so that it can be pasted on the adhesive sheet 3 cut in the same row of the composite film.
[0058] like Figure 4 、 Figure 5 、 Figure 6 、 Figure 10 and Figure 11 As shown, the positioning strip 73 is in the shape of a long strip, and the width direction of the positioning strip 73 is arranged vertically. The outer side wall of the positioning strip 73 can fit into the groove wall of the positioning groove 72a. The middle part of the hinge shaft 74 is connected to the unloading cylinder 76, and the piston rod 76a of the unloading cylinder 76 is fixedly connected to the front end of the unloading tray 72. All positioning strips 73 are located behind the hinge shaft 74, and the positioning strips 73 are arranged parallel to each other. Multiple positioning strips 73 are evenly distributed along the front and rear directions. The upper end face of the positioning strip 73 is flush with the upper end face of the support plate 71, and a plurality of adsorption holes 72b are provided in front of the unloading tray 72.
