Description

Technical Field

[0001] This utility model relates to the field of flexible electronic processing technology, and in particular to an aluminum silver paste dipping device. Background Technology

[0002] FPC (Flexible Printed Circuit Board) is a flexible circuit board made of polyimide or polyester film as a substrate. It features high reliability, thinness, and three-dimensional wiring. In medical devices, it can be used for external heating therapy.

[0003] During the processing of FPC boards for heating therapy, silver paste needs to be coated at the nodes of the heating area of ​​the FPC board to concentrate the heat output, which can achieve the effect of local high conductivity and heat conduction.

[0004] Currently, in the coating process, silver paste is usually applied to the nodes manually using a screen. Workers need to repeatedly position the coating, which can easily lead to deviations in the coating points, making it time-consuming and labor-intensive. Utility Model Content

[0005] To address the aforementioned problems, this application provides an aluminum silver paste dipping device.

[0006] This application provides an aluminum silver paste dipping device, which adopts the following technical solution: An aluminum silver paste dipping device includes a frame, a paste holding mechanism for holding silver paste, a coating mechanism for coating silver paste onto an FPC board, and a drive mechanism for moving the coating mechanism. The slurry-holding mechanism includes a feeding plate mounted on the frame; The coating mechanism includes several sponge heads; The upper end of the feeding plate is provided with several feeding slots, which are adapted to the sponge head and correspond one-to-one. The fixed end of the drive mechanism is located on one side of the frame; The sponge head is located at the moving end of the drive mechanism.

[0007] By adopting the above technical solution, the driving mechanism is manipulated to move the coating mechanism, and several sponge heads are used to pick up the silver paste in the paste holding mechanism and then apply the silver paste to the FPC board. This method is highly efficient and does not require manual positioning. When the coating mechanism is used too many times, it can also be cleaned by the cleaning mechanism to ensure the coating effect on the FPC board.

[0008] Optionally, the movable end of the drive mechanism is provided with a fixed plate, and the coating mechanism includes a pressing assembly installed below the fixed plate. The pressing assembly includes a movable plate and several elastic elements, which are all disposed between the movable plate and the fixed plate, and several sponge heads are all disposed at the lower end of the movable plate.

[0009] By adopting the above technical solution, when applying silver paste, the fixed plate is moved closer to the movable plate, and several elastic elements are compressed, thereby increasing the pressure on the movable plate and the sponge head, and adhering the silver paste on the sponge head to the FPC board, thereby increasing the amount of silver paste adhering to the FPC board and improving product quality.

[0010] Optionally, the movable plate is slidably connected to the fixed plate, and a number of guide posts are provided on the side of the movable plate near the fixed plate. The fixed plate is provided with limiting holes that are adapted to the number of guide posts, and the guide posts slide within the limiting holes.

[0011] By adopting the above technical solution, the guide column can play a guiding role, thereby improving the stability of the fixed plate moving towards the moving plate, thereby increasing the pressure on the sponge head, ensuring the amount of silver paste adhering to the FPC board, and thus ensuring product quality.

[0012] Optionally, the frame is provided with a feeding assembly, which includes a hopper and a scraper. The hopper is slidably connected to the frame, and a feeding port is opened at the bottom of the hopper. The scraper is located at the bottom of the hopper and surrounds the feeding port. The end of the scraper away from the hopper is attached to the upper surface of the feeding plate.

[0013] By adopting the above technical solution, during feeding, the hopper is slid above several feeding troughs. At this time, some silver paste enters the feeding troughs. Then, the hopper is slid away from the feeding troughs, and the scraper cleans the silver paste on the surface of the feeding plate, thus completing the feeding. The structure is simple and the feeding is convenient.

[0014] Optionally, a cleaning mechanism mounted on the frame is also included, which includes a cleaning cloth for cleaning the sponge head.

[0015] By adopting the above technical solution, after the sponge head has been dipped in silver paste a certain number of times, several sponge heads can be placed on the cleaning cloth for cleaning, thereby improving the subsequent paste dipping effect and improving product quality.

[0016] Optionally, the cleaning mechanism further includes an unwinding roller and a take-up roller, which rotate at both ends of the frame width direction, with one end of the cleaning cloth in the length direction wound around the unwinding roller and the other end of the cleaning cloth in the length direction wound around the take-up roller.

[0017] By adopting the above technical solution, after cleaning the sponge head once, the unwinding roller can be operated to unwind the cleaning cloth, and the take-up roller can be operated to take up the used cleaning cloth, thereby improving the subsequent cleaning effect of the sponge head and making cleaning more convenient.

[0018] Optionally, a plurality of sponge heads are disposed on one side of the movable plate along its length, and a plurality of cleaning heads are disposed on the other side of the movable plate along its length, with the spacing between the plurality of sponge heads being the same as the spacing between the plurality of cleaning heads.

[0019] By adopting the above technical solution, when several sponge heads apply silver paste to the FPC board, several cleaning heads come into contact with the positions on the FPC board where silver paste will be applied later, and clean the surface of the positions on the FPC board where silver paste will be applied later, thereby improving the silver paste adhesion effect of the subsequent FPC board.

[0020] In summary, this application includes at least one of the following beneficial technical effects: The driving mechanism moves the coating mechanism, which uses several sponge heads to pick up silver paste from the paste-holding mechanism and then coats the silver paste onto the FPC board. This method is highly efficient and does not require manual positioning. When the coating mechanism is used too many times, it can be cleaned by the cleaning mechanism to ensure the coating effect on the FPC board. During the silver paste application process, the fixed plate is moved closer to the movable plate, compressing several elastic elements and increasing the pressure on the movable plate and the sponge head. This causes the silver paste adhering to the sponge head to be transferred to the FPC board, thereby increasing the amount of silver paste adhering to the FPC board and improving product quality.

Detailed Implementation

[0027] The present application will be further described in detail below with reference to all the accompanying drawings.

[0028] This application discloses an aluminum silver paste dipping device.

[0029] Reference Figure 1 and Figure 2 An aluminum silver paste dipping device includes a frame 1, a paste holding mechanism for holding silver paste, a coating mechanism for coating silver paste onto an FPC board 100, a drive mechanism 3 for moving the coating mechanism, and a cleaning mechanism for cleaning the coating mechanism. An FPC board 100 to be dipped is provided on one side of the frame 1. The driving mechanism 3 drives the coating mechanism to pick up the silver paste from the paste holding mechanism, and then coats the silver paste onto the FPC board 100. When the coating mechanism is used too many times, the cleaning mechanism can also clean the coating mechanism to ensure the coating effect on the FPC board 100.

[0030] Reference Figure 1 and Figure 3 The slurry holding mechanism includes a feeding plate 11, a cylinder 12, a limiting rod, and a feeding assembly. The upper end of the feeding plate 11 is provided with several feeding grooves 111. The feeding assembly includes a hopper 5 and a scraper 6. One side of the hopper 5 is fixedly connected to the piston of the cylinder 12, and the other side of the hopper 5 is slidably connected to the limiting rod. The bottom of the hopper 5 is provided with a feeding port. The scraper 6 is located at the bottom of the hopper 5 and surrounds the feeding port. The end of the scraper 6 away from the hopper 5 is attached to the upper surface of the feeding plate 11. Silver paste is placed in the hopper 5. When replenishing the paste, the piston of the cylinder 12 is moved to move the hopper 5 above the feeding trough 111. Some silver paste enters the feeding trough 111. Then the piston of the cylinder 12 is moved to move the hopper 5 away from the feeding trough 111. The scraper 6 scrapes the silver paste off the upper surface of the feeding plate 11.

[0031] Reference Figure 4 and Figure 5 The coating mechanism includes a fixed plate 31, a pressing assembly, several sponge heads 2, and a cleaning head 312. The pressing assembly is installed below the fixed plate 31 and includes a movable plate 32 and several elastic elements 4. The elastic elements 4 are all disposed between the movable plate 32 and the fixed plate 31. The movable plate 32 is slidably connected to the fixed plate 31. Several guide posts 321 are provided on the side of the movable plate 32 near the fixed plate 31. The fixed plate 31 has limiting holes 311 adapted to the several guide posts 321, and the guide posts 321 slide within the limiting holes 311. Several sponge heads 2 and cleaning heads 312 are all disposed at the lower end of the movable plate 32. Several sponge heads 2 and a feeding trough 111 (see reference) Figure 3 One-to-one correspondence.

[0032] In one specific implementation, the cylinder in this embodiment is preferably a rodless cylinder. In other embodiments, a cylinder, a hydraulic cylinder, or an electric cylinder can also be used to drive the hopper 5.

[0033] Reference Figure 1 The drive mechanism 3 includes a robotic arm. The fixed end of the robotic arm is located on one side of the frame 1, and the movable end of the robotic arm is equipped with an electric cylinder. The piston rod of the electric cylinder is connected to the upper end of the fixed plate 31.

[0034] Reference Figure 1 and Figure 5 The robotic arm drives the coating mechanism to move above the loading plate 11. Then, the piston rod of the electric cylinder extends, placing several sponge heads 2 into the loading trough 111, where silver paste adheres to the sponge heads 2. The robotic arm drives the electric cylinder and coating mechanism to move above the FPC board 100. The piston rod of the electric cylinder extends, moving the fixed plate 31, movable plate 32, sponge heads 2, and cleaning head 312 closer to the FPC board 100, where several sponge heads 2 come into contact with the FPC board 100. As the electric cylinder continues to press down, the fixed plate 31 moves closer to the movable plate 32, compressing several elastic elements 4, thereby increasing the pressure on the movable plate 32 and sponge heads 2, and adhering the silver paste on the sponge heads 2 to the FPC board 100, thus increasing the amount of silver paste adhered. At this time, several cleaning heads 312 come into contact with the positions on the FPC board 100 where silver paste will be applied later, cleaning the FPC board 100 and thus improving the subsequent silver paste adhesion effect.

[0035] In one specific implementation, the elastic element 4 in this embodiment is preferably a spring. In other embodiments, it can also be other elastic elements 4, as long as they can compress the sponge head 2.

[0036] Then, the feeding component is manipulated to add silver paste to the upper feed tank 111, and the robotic arm is manipulated to move the coating mechanism to the paste holding mechanism, so that the sponge head 2 is dipped in silver paste again and contacts the position of the subsequent silver paste to be applied to the FPC board 100. The efficiency is high and the coating accuracy is high.

[0037] Reference Figure 2 and Figure 5 The cleaning mechanism includes a cleaning cloth 7, an unwinding roller 8, and a winding roller 9. The unwinding roller 8 and the winding roller 9 rotate at both ends of the width direction of the frame 1, respectively. One end of the cleaning cloth 7 is wound around the unwinding roller 8, and the other end of the cleaning cloth 7 is wound around the winding roller 9. After the sponge head 2 is dipped in paste a certain number of times, the sponge head 2 is moved onto the cleaning cloth 7 by a robotic arm in conjunction with an electric cylinder. The cleaning cloth 7 cleans the surface of the sponge head 2, thereby increasing the amount of silver paste that the sponge head 2 can dip in at one time, thus increasing the amount of silver paste adhered to the FPC board 100 and improving product quality.

[0038] After cleaning the sponge head 2 once, the unwinding roller 8 can be operated to unwind the cleaning cloth 7, and the take-up roller 9 can be operated to take up the used cleaning cloth 7, thereby improving the subsequent cleaning effect on the sponge head 2 and making cleaning more convenient.

[0039] The implementation principle of the aluminum silver paste dipping device in this embodiment is as follows: Silver paste is added to the loading tank 111 via a sliding hopper 5. Then, the hopper 5 is moved away from the loading tank 111 to make room. A robotic arm is manipulated to move the coating mechanism, moving the sponge head 2 into the loading tank 111 to dip into the silver paste. The robotic arm then moves the coating mechanism above the FPC board 100. The piston rod of the electric cylinder extends, causing the fixed plate 31, movable plate 32, sponge head 2, and cleaning head 312 to move closer to the FPC board 100, with several sponge heads 2 contacting the FPC board 100. As the electric cylinder continues to press down, the fixed plate 31 moves closer to the movable plate 32. Several elastic elements 4 are compressed, thereby increasing the pressure on the movable plate 32 and the sponge head 2, and adhering the silver paste on the sponge head 2 to the FPC board 100, thereby increasing the amount of silver paste adhering and making the coating more precise. At this time, several cleaning heads 312 contact the position of the FPC board 100 where the silver paste is to be applied later, and clean the FPC board 100, thereby improving the subsequent silver paste adhesion effect. After the sponge head 2 is dipped in paste a certain number of times, the robotic arm and electric cylinder move the sponge head 2 to the cleaning cloth 7. The cleaning cloth 7 cleans the surface of the sponge head 2, thereby increasing the amount of silver paste that the sponge head 2 can dip in at one time, thereby increasing the amount of silver paste adhering to the FPC board 100 and improving product quality.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
