Description

Technical Field

[0001] This utility model relates to the field of medical device manufacturing technology, and in particular to a hydrogel physiotherapy patch for attaching flexible circuit boards and non-woven fabric devices. Background Technology

[0002] Hydrogel therapy patches are a type of physical therapy product widely used to relieve muscle soreness and promote blood circulation. Their core components typically include a flexible circuit board with conductive properties, a non-woven fabric layer, and a hydrogel layer. The flexible circuit board conducts signals or energy, the non-woven fabric provides support and comfort, and the hydrogel layer adheres directly to the skin to deliver the therapeutic effect. During the production of hydrogel therapy patches, the flexible circuit board and non-woven fabric must be accurately adhered to the material strip to ensure product functionality and user experience.

[0003] In existing physiotherapy patch production equipment, the adhesion of flexible circuit boards and non-woven fabrics is typically accomplished using mechanical grippers or vacuum adsorption devices. However, in actual operation, this is easily affected by various factors, such as inaccurate positioning of the mechanical grippers, insufficient adsorption force, and offset during the movement of the material belt. These factors can cause deviations in the bonding position of the flexible circuit board on the material belt. Such deviations not only affect the appearance and function of the physiotherapy patch but may also render the product unusable, severely impacting production efficiency and product quality.

[0004] Therefore, there is an urgent need for a device that can improve the accuracy of the bonding position of flexible circuit boards and non-woven fabrics. By optimizing the picking and bonding mechanism, the flexible circuit board can be accurately attached to the designated position on the material strip, thereby solving the bonding position deviation problem in the existing technology and improving the production efficiency and quality of hydrogel therapy patches. Utility Model Content

[0005] In view of at least one of the above technical problems, the present invention provides a device for attaching a hydrogel physiotherapy patch to a flexible circuit board and a non-woven fabric, thereby improving the adhesion accuracy through structural improvements.

[0006] According to a first aspect of the present invention, a hydrogel therapy patch with a flexible circuit board and a nonwoven fabric device is provided, comprising: The material conveying mechanism includes multiple sets of roller assemblies arranged along the material conveying line, as well as a flexible circuit board positioning assembly and a non-woven fabric positioning assembly. The roller assemblies convey the material belt with positioning holes. Both the flexible circuit board positioning assembly and the non-woven fabric positioning assembly include positioning plates. The positioning plates can be relatively close to or far away from the surface of the material belt. A flexible circuit board feeding mechanism is provided on one side of the material conveying mechanism, including a feeding station, wherein the feeding station has a material tray for placing flexible circuit boards; A flexible circuit board picking mechanism includes a flexible circuit board picking claw that can be relatively moved between the flexible circuit board positioning component and the feeding station. A non-woven fabric feeding mechanism is located on one side of the material conveying mechanism; The nonwoven fabric feeding mechanism includes a nonwoven fabric feeding claw that can be relatively moved between the nonwoven fabric feeding mechanism and the nonwoven fabric positioning component. The positioning plate has a positioning pin, which is positioned opposite to the positioning hole. The positioning plate is attached to the material belt, and the positioning pin extends into the positioning hole.

[0007] In some embodiments of this utility model, both the flexible circuit board positioning assembly and the nonwoven fabric positioning assembly include a lifting drive component and a fixing plate connected to the output end of the lifting drive component.

There is a gap between the positioning plate and the fixed plate. When the positioning pin is configured such that there is a gap between the positioning plate and the fixed plate, the end of the positioning pin is lower than the surface of the positioning plate near the material belt. When the positioning plate and the fixed plate are in contact, the end of the positioning pin extends out of the positioning plate.

[0009] In some embodiments of this utility model, the positioning plate also has two limiting strips arranged opposite to each other on both sides of the material belt running direction, and the side of the limiting strip has an arc groove opposite to the position of the pin hole.

[0010] In some embodiments of this utility model, a first paper guide roller is disposed on opposite ends of the fixed plate, and a second paper guide roller is disposed on opposite ends of the positioning plate, with a material belt passing between the first paper guide roller and the second paper guide roller.

[0011] In some embodiments of this utility model, the flexible circuit board feeding mechanism further includes a material preparation station for placing multiple full material trays and a material unloading station for placing empty material trays. The material conveying station is located between the material preparation station and the material unloading station. The material preparation station, the material conveying station and the material unloading station are also provided with a transmission component that can be relatively slidably arranged to pick up and place material trays.

[0012] In some embodiments of this utility model, both the material preparation station and the unloading station have a hopper for placing multiple material trays. The hopper has a discharge port and a gripper for holding the material trays at the discharge port. It also has a receiving component arranged opposite to the discharge port, including at least two receiving plates that can be relatively close to or away from the material trays.

[0013] In some embodiments of this utility model, the flexible circuit board positioning assembly and the material conveying station are further provided with a positioning detection mechanism, including a positioning detection plate of the same size as the flexible circuit board. The positioning detection plate is provided with baffles on two adjacent sides, and push plates that can be relatively close to or far away from the positioning detection plate are provided on two adjacent sides.

[0014] In some embodiments of this utility model, the flexible circuit board picking claw has two parts: one can move relatively between the flexible circuit board positioning component and the positioning detection mechanism, and the other can be relatively moved between the positioning detection mechanism and the material conveying station.

[0015] In some embodiments of this utility model, the roller assembly at the end of the material belt in the output direction also has a waste discharge assembly. The waste discharge assembly includes a waste discharge shovel fixedly connected to the roller assembly, and the waste discharge shovel and the material belt are adjustable and can be scheduled together.

[0016] The beneficial effects of this utility model are as follows: By setting multiple sets of roller assemblies in the material conveying mechanism, and combining them with a material belt with positioning holes and positioning pins, this utility model ensures that the material belt can be accurately positioned during the conveying process, thereby providing a reliable foundation for the subsequent adhesion of flexible circuit boards and non-woven fabrics; the flexible circuit board positioning assembly and the non-woven fabric positioning assembly, through the positioning plate, further combine the positioning pins with the positioning holes on the material belt to precisely limit the bonding position of the flexible circuit board and the non-woven fabric, effectively avoiding bonding errors caused by improper positioning; through the cooperation of the flexible circuit board feeding mechanism, the flexible circuit board picking mechanism, the non-woven fabric feeding mechanism, and the non-woven fabric picking mechanism, the automated operation from feeding to bonding is realized, and the relative movement design of the picking claws improves the flexibility of operation and the bonding accuracy.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] This invention features a dedicated circular die-cutting station before the flexible circuit board and nonwoven fabric bonding stations. This station processes the hydrogel and graphite assembly using a circular die. The die-cutting machine precisely cuts the assembly with a circular blade, ensuring dimensional consistency and processing accuracy, thus providing a precisely matched substrate for subsequent bonding processes. After processing, the assembly is mechanically rotated 180° to remove the backing film, exposing the substrate and improving its compatibility with the flexible circuit board and nonwoven fabric bonding processes. During production, the assembly enters the flexible circuit board and nonwoven fabric bonding station without tension. This effectively prevents deformation or misalignment of the substrate due to tension changes during transport, providing a more accurate material reference for subsequent bonding operations. This creates favorable conditions for precise bonding of the flexible circuit board and nonwoven fabric, providing technical support for the efficiency and reliability of the entire production line.

[0024] like Figures 1 to 9 The hydrogel therapy patch with flexible circuit board and non-woven fabric shown includes: The material conveying mechanism 1 includes multiple sets of roller assemblies 11 arranged along the material conveying line, as well as a flexible circuit board positioning assembly 12 and a non-woven fabric positioning assembly 13. The roller assembly 11 conveys the material belt with positioning holes. Both the flexible circuit board positioning assembly 12 and the non-woven fabric positioning assembly 13 include positioning plates 14, which can be relatively close to or away from the surface of the material belt. It should be noted that the roller assembly 11 can take many forms, such as an air-expanding shaft, a roller with anti-slip texture, or a flexible roller, or other types of rollers. In this invention, the material belt enters without tension, and the rollers mainly serve to support and guide it. Specifically, the material belt in this invention has positioning holes. To improve the accuracy of pasting the flexible circuit board and non-woven fabric, the positioning pins 14a cooperate with the positioning holes to prevent the material belt from shifting during pasting, thereby improving the accuracy of pasting. Meanwhile, when pasting flexible circuit boards or non-woven fabrics, first attach the positioning plate 14 to the material strip, and then raise the positioning pin 14a and insert it into the positioning hole to achieve positioning.

[0025] The flexible circuit board feeding mechanism 2 is located on one side of the material conveying mechanism 1, including a feeding station 21, and a material tray 22 for placing flexible circuit boards is provided on the feeding station 21. The flexible circuit board picking mechanism 3 includes a flexible circuit board picking claw 31 that can be relatively movable between the flexible circuit board positioning component 12 and the conveying station 21. The flexible circuit board picking claw 31 picks up the material tray 22 on the conveying station 21 and transfers it to the material conveying mechanism 1 to bond the positioned material strip. It should be noted that the flexible circuit board picking claw 31 can take many forms, such as an adsorption picking claw, a mechanical gripper, or an electrostatic picking claw, etc., which can pick up flexible circuit boards.

[0026] The nonwoven fabric feeding mechanism 4 is located on one side of the material conveying mechanism 1. It should be noted that the nonwoven fabric feeding mechanism 4 can take many forms, such as a roll-type nonwoven fabric supply mechanism, a single-piece automatic separation supply mechanism, or other forms that can supply nonwoven fabric.

[0027] The nonwoven fabric picking mechanism 5 includes a nonwoven fabric picking claw 51 that can be relatively moved between the nonwoven fabric feeding mechanism 4 and the nonwoven fabric positioning component 13; it has the same form as the flexible circuit board picking mechanism 3 described above, and will not be described again here.

[0028] The positioning plate 14 has a positioning pin 14a, which is positioned opposite to the positioning hole. The positioning plate 14 is in contact with the material belt, and the positioning pin 14a extends into the positioning hole.

[0029] like Figure 1 , Figure 2As shown, in the specific working process of this utility model, the material conveying mechanism 1 transmits the material belt through multiple sets of roller assemblies 11 arranged along the material belt conveying line. The material belt has pre-set positioning holes, and the flexible circuit board positioning assembly 12 and the non-woven fabric positioning assembly 13 cooperate with the positioning plate 14 for precise spatial positioning. The positioning plate 14 is provided with positioning pins 14a, which are positioned opposite to the positioning holes on the material belt. When the positioning plate 14 gradually adheres to the material belt, the positioning pins 14a extend into the positioning holes, achieving a reliable positioning effect and ensuring the stability and accuracy of the material belt during transmission. The flexible circuit board is fed through the flexible circuit board feeding mechanism 2, which is located on one side of the material conveying mechanism 1. A material tray 22 for storing flexible circuit boards is placed on the conveying station 21. The flexible circuit board picking mechanism 3 is located between the flexible circuit board positioning assembly 12 and the conveying station 21. Its flexible circuit board picking claw 31 picks up the flexible circuit board from the material tray 22 by relative movement and precisely places it into the designated flexible circuit board positioning area on the material belt. Nonwoven fabric feeding is achieved by nonwoven fabric feeding mechanism 4, which is located on the other side of material conveying mechanism 1. Nonwoven fabric picking mechanism 5, through linkage with nonwoven fabric feeding mechanism 4 and nonwoven fabric positioning component 13, realizes nonwoven fabric picking and positioning. During the relative movement, nonwoven fabric picking claw 51 picks up nonwoven fabric from the feeding station and accurately places it into the predetermined nonwoven fabric positioning area on the material belt.

[0030] This invention, by setting multiple sets of roller assemblies 11 in the material conveying mechanism 1, and combining them with a material belt with positioning holes and positioning pins 14a, ensures that the material belt can be accurately positioned during the conveying process, thereby providing a reliable foundation for the subsequent adhesion of flexible circuit boards and non-woven fabrics. The flexible circuit board positioning assembly 12 and the non-woven fabric positioning assembly 13, through the positioning plate 14, further combine the positioning pins 14a with the positioning holes on the material belt to accurately limit the bonding position of the flexible circuit board and the non-woven fabric, effectively avoiding bonding errors caused by improper positioning. Through the cooperation of the flexible circuit board feeding mechanism 2, the flexible circuit board picking mechanism 3, the non-woven fabric feeding mechanism 4, and the non-woven fabric picking mechanism 5, the automated operation from feeding to bonding is realized, and the relative movement design of the picking claws improves the flexibility of operation and the bonding accuracy.

[0031] The material belt is transported without tension, and it is usually in a stretched or relaxed state during transport. This can easily cause wrinkles or undulations when it is applied to flexible circuit boards and non-woven fabrics, thus affecting the accuracy and stability of the bonding process. Figures 3 to 5As shown, in some embodiments of this utility model, both the flexible circuit board positioning assembly 12 and the nonwoven fabric positioning assembly 13 include a lifting drive 15 and a fixing plate 16 connected to the output end of the lifting drive 15. The fixing plate 16 and the positioning plate 14 are arranged parallel to each other. A positioning pin 14a is fixedly installed on the fixing plate 16. The positioning plate 14 has a pin hole 16a through which the positioning pin 14a passes. The lifting drive 15 drives the fixing plate 16 and the positioning plate 14 to move relatively closer or further away from the material belt. By setting the lifting drive 15 in the flexible circuit board positioning assembly 12 and the nonwoven fabric positioning assembly 13, the fixing plate 16 and the positioning plate 14 are driven to move in coordination, thereby achieving effective support and laying of the material belt. Under the action of the lifting drive 15, the fixing plate 16 drives the positioning pin 14a to push the material belt upward. The positioning pin 14a accurately extends into the positioning hole on the material belt, completing the support and positioning of the material belt, thereby keeping the material belt in a flat state. This ensures that the material belt can be laid accurately and flat evenly under tension-free transmission, providing a stable foundation for the precise bonding of flexible circuit boards and non-woven fabrics. Simultaneously, the positioning plate 14 has pin holes 16a through which positioning pins 14a pass. The positioning pins 14a can extend or retract into the pin holes 16a, preventing them from contacting the material belt during transmission and thus avoiding any impact on the conveying process.

[0032] Based on the above technical solutions, we will continue to refer to Figures 3 to 5The positioning pin 14a can extend or retract into the pin hole 16a to ensure more precise timing of its insertion and locking. A compression assembly 17 is also included, comprising a cylinder 17a fixedly connected to a fixed plate 16, and a piston rod 17b fixedly connected to the positioning plate 14. A gap 18 exists between the positioning plate 14 and the fixed plate 16. When the gap 18 exists between the positioning plate 14 and the fixed plate 16, the end of the positioning pin 14a is lower than the surface of the positioning plate 14 closest to the material conveyor belt; when the positioning plate 14 and the fixed plate 16 are in contact, the end of the positioning pin 14a extends beyond the positioning plate 14. The compression assembly 17, comprising the cylinder 17a fixedly connected to the fixed plate 16 and the piston rod 17b fixedly connected to the positioning plate 14, forms a flexible movement structure between the positioning plate 14 and the fixed plate 16. When a gap 18 is maintained between the positioning plate 14 and the fixing plate 16, the end of the positioning pin 14a is lower than the surface of the positioning plate 14 near the material belt, keeping the positioning pin 14a hidden and preventing contact with the material belt, thus avoiding interference with the material belt when not in operation. When the compression drive unit drives the positioning plate 14 to adhere to the fixing plate 16, the end of the positioning pin 14a extends outside the positioning plate 14 and is precisely inserted into the positioning hole on the material belt. This achieves effective compaction and flattening of the material belt, completing the precise positioning function and ensuring that the material belt remains stable and tension-free during the bonding process. It should be noted that the compression component 17 can flexibly adjust the compaction action of the positioning plate 14 according to the thickness, material, and actual transmission state of the material belt, ensuring uniform pressure distribution and stable, flat material, significantly improving the accuracy and reliability of flexible circuit board and non-woven fabric bonding.

[0033] The material conveyor belt may deviate or misalign in its running direction due to uneven tension or external interference. This problem not only affects the bonding and alignment accuracy of the flexible circuit board and non-woven fabric, but may also prevent the positioning pin 14a from being accurately inserted into the positioning hole, seriously affecting production efficiency and product quality. Figures 3 to 5As shown, the positioning plate 14 also has two limiting strips 14b arranged opposite each other on both sides of the material conveyor belt's running direction. The limiting strips 14b have arc-shaped grooves 14b1 on their sides that correspond to the positions of the pin holes 16a. The two limiting strips 14b on the positioning plate 14 are arranged opposite each other on both sides of the material conveyor belt's running direction, and have arc-shaped grooves 14b1 on their sides that correspond to the positions of the pin holes 16a, thus providing additional lateral limiting function when the positioning pin 14a engages with the material conveyor belt. When the material conveyor belt reaches the pasting station, the limiting strips 14b can precisely constrain both sides of the material conveyor belt, while the arc-shaped grooves 14b1, while maintaining compatibility with the positioning pin 14a, further ensure that the positioning pin 14a and the positioning hole of the material conveyor belt can be precisely aligned. When the pin hole 16a enters the constrained area of ​​the limiting strip 14b through the arc-shaped groove 14b1, the position of the material conveyor belt around its perimeter is completely fixed, preventing interference with precise pasting due to positional offset.

[0034] The material conveyor belt rises under the drive of the lifting drive component 15, and is positioned by the locating pin 14a. However, loosening may still occur in the extension direction of the material conveyor belt due to the lack of tension. Figures 3 to 5 As shown, the system also includes a first guide roller 16b disposed at opposite ends of the fixed plate 16, and a second guide roller 14c disposed at opposite ends of the positioning plate 14. The material belt passes between the first guide roller 16b and the second guide roller 14c. By disposing of the first guide roller 16b at opposite ends of the fixed plate 16 and the second guide roller 14c at opposite ends of the positioning plate 14, a flexible combination of guiding and supporting functions is achieved. The material belt passes between the first guide roller 16b and the second guide roller 14c, and is lifted and positioned by the lifting drive 15. The first guide roller 16b is fixed to the fixed plate 16, providing initial stable support on the transmission path and ensuring that the material belt is in a controllable state before entering the positioning area. The second guide roller 14c is fixed to the positioning plate 14 and its height is flexibly adjusted according to the lifting action of the positioning plate 14. When the lifting drive component 15 drives the positioning plate 14 to rise, the second guide roller 14c effectively lifts the material strip, unfolds it flat, and keeps it firm and stable during the bonding of the flexible circuit board and non-woven fabric. Through multi-point dynamic support, it plays a role in fixing the material strip, preventing displacement and unevenness, thus providing a reliable guarantee for the accurate insertion of the positioning pin 14a and the subsequent bonding process.

[0035] To achieve fully automated production on the production line and improve production efficiency. For example... Figure 6 , Figure 7As shown, in some embodiments of this utility model, the flexible circuit board feeding mechanism 2 further includes a preparation station 23 for placing multiple full material trays 22, and a discharge station 24 for placing empty material trays 22. A conveying station 21 is located between the preparation station 23 and the discharge station 24. A transmission component 25 is also provided between the preparation station 23, the conveying station 21, and the discharge station 24, which can be relatively slidably arranged to pick up and place material trays 22. The preparation station 23 is used to place multiple full material trays 22 to ensure a continuous supply to meet production needs; the conveying station 21 serves as the core material supply point, supplying the flexible circuit boards from the full material trays 22 to the material picking mechanism piece by piece; the discharge station 24 is used to place empty material trays 22, realizing closed-loop management of material flow. The transmission component 25 acts as a bridge connecting the material preparation station 23, the material conveying station 21, and the material unloading station 24. It can slide and convey the material tray 22 between each station, ensuring that the full tray of material quickly enters the material conveying station 21, while automatically transferring the empty tray of material to the material unloading station 24. This makes the entire feeding process efficient and continuous, and realizes fully automated operation.

[0036] like Figure 6 , Figure 7 As shown, in some embodiments of this utility model, both the material preparation station 23 and the unloading station 24 have a hopper 26 for placing multiple material trays 22. The hopper 26 has a discharge port 26a and a gripper 26b set at the discharge port 26a to hold the material trays 22. It also has a receiving component 27 arranged opposite to the discharge port 26a, including at least two receiving plates 27a that can be relatively close to or away from the material trays 22.

[0037] The hopper 26 stores multiple material trays 22. Its compact structure adapts to continuous production requirements. Grippers 26b are positioned at the outlet 26a of the hopper 26 to precisely grip the material trays 22, preventing slippage or tipping during operation. The receiving assembly 27 consists of at least two receiving plates 27a that can be positioned relative to or away from the material trays 22. Its function is to first contact and lift the material trays 22 within the hopper 26, then the grippers 26b open to release the current material tray 22. The receiving assembly 27 then moves down to the position of one more material tray 22, followed by grippers 26b gripping the next material tray 22. The receiving assembly 27 then smoothly transfers the previously released material tray 22 to the next workstation. This operational process, through the flexible cooperation of the grippers 26b and the receiving assembly 27, ensures the sequential separation and precise transfer of the material trays 22 within the hopper 26, maintaining the trays 22 in a stable and orderly manner at all times.

[0038] When the transfer component 25 moves to the unloading station 24, it moves the empty material tray 22 to the discharge port 26a of the hopper 26 at the unloading station 24. Simultaneously, the gripper 26b reopens, and through the pushing action of the receiving component 27, the empty material tray 22 is precisely fed into the hopper 26. After pushing, the gripper 26b clamps all the material trays 22 in the hopper 26, and the receiving component 27 moves back to its initial position, ensuring safety and stability during operation. This achieves efficient dynamic management of multiple material trays 22 and optimizes the operation process of flexible circuit board loading and empty tray recycling through real-time separation and transfer.

[0039] In the process of loading and positioning flexible circuit boards, ensuring that each flexible circuit board accurately enters the positioning area and meets the precision requirements of the workstation is key to improving production quality and efficiency. For example... Figure 8 As shown, a positioning detection mechanism 6 is also provided between the flexible circuit board positioning assembly 12 and the conveying station 21. This mechanism includes a positioning detection plate 61 of the same size as the flexible circuit board. The positioning detection plate 61 has baffles 61a on its two adjacent sides, and push plates 61b on its two adjacent sides that can move closer to or further away from the positioning detection plate 61. By setting the positioning detection mechanism 6 between the flexible circuit board positioning assembly 12 and the conveying station 21, precise detection and dynamic adjustment of the flexible circuit board's transmission status are achieved. The positioning detection mechanism 6 includes a positioning detection plate 61 of the same size as the flexible circuit board, ensuring complete coverage of the detection range. Baffles 61a are provided on the two adjacent sides of the positioning detection plate 61 to physically restrict the lateral position of the flexible circuit board, preventing positional misalignment due to inertial sliding or transport deviation. Push plates 61b are provided on the other two sides of the positioning detection plate 61, which can move closer to or further away from the positioning detection plate 61. The push plates 61b can be dynamically adjusted to precisely fine-tune the edges of the flexible circuit board, correcting any deviation from the detection plate area back to the correct position. The dynamic correction method significantly improves the precision control capability, ensuring that the flexible circuit board is always in the optimal position when entering the positioning component area.

[0040] The aforementioned positioning adjustment of the flexible circuit board by the six-pronged inspection mechanism is designed to make the picking-up of the flexible circuit board by the claw 31 more convenient and faster. For example... Figure 2As shown, there are two flexible circuit board picking claws 31. One is movable relative to the flexible circuit board positioning assembly 12 and the arrival detection mechanism 6, and the other is movable relative to the arrival detection mechanism 6 and the conveying station 21. One picking claw is movable relative to the arrival detection mechanism 6 and the conveying station 21 to pick up the flexible circuit board from the conveying station 21 and deliver it to the arrival detection mechanism 6. The other picking claw is movable relative to the flexible circuit board positioning assembly 12 and the arrival detection mechanism 6 to pick up the flexible circuit board from the flexible circuit board positioning assembly 12 or the arrival detection mechanism 6 and complete the internal transfer within the area. The dual picking claws, through the phased relay transfer at multiple stations, avoid the efficiency bottleneck of the original single picking claw long-path operation. After the fine-tuning of the position of the arrival detection mechanism 6, the flexible circuit board can be picked up again and pasted onto the material belt more accurately, improving the transfer efficiency of the flexible circuit board and the smoothness of the process connection.

[0041] During the production of hydrogel therapeutic patches, as the process progresses, excess edge material or waste is usually generated after the pasting process is completed. This waste needs to be processed through a waste removal device. For example... Figure 9 As shown, the roller assembly 11 at the output end of the material belt also has a waste removal component 19. The waste removal component 19 includes a waste removal shovel 19a fixedly connected to the roller assembly 11, and the waste removal shovel 19a and the material belt can be adjusted and configured. By adding the waste removal component 19 to the roller assembly 11 at the output end of the material belt, automatic removal and efficient processing of waste are achieved. The waste removal component 19 includes a waste removal shovel 19a fixedly connected to the roller assembly 11, and the waste removal shovel 19a can be flexibly configured and configured with the material belt by adjusting its position. During the conveying process, the waste material is transported to the output end with the material belt, and the waste removal shovel 19a quickly and stably separates it by direct contact with the waste material and guides it to the waste recycling area or waste collection device. This ensures the cleanliness and smoothness of the production line and provides more flexible adaptability for material belts of different specifications and materials.
