Description

Technical Field

[0001] This utility model relates to the field of flexible circuit board (FPCB) interconnection technology, and in particular to a flexible circuit board manufacturing device for pure FPCB interconnection. Background Technology

[0002] Pure flexible circuit board (PVC) adapters refer to the efficient transmission and connection of signals and power between different functional modules in flexible electronic systems by leveraging the bendability and lightweight characteristics of flexible circuit boards. Compared to traditional rigid circuit board adapters, PVC adapters do not require additional connectors or complex mechanical fixing structures. They can be freely bent and folded according to the internal space layout of the device, greatly saving space and improving the integration and portability of electronic devices. The flexible circuit board is a printed circuit with high reliability and excellent flexibility made of flexible insulating materials such as polyimide or polyester film. The flexible substrate with double-layer circuit design is used to meet the needs of long-distance circuit connection.

[0003] Traditional manufacturing methods are extremely inconvenient for transport due to the limited size of the worktable, making mass production impossible. Furthermore, during the etching process, the long circuit boards make it difficult to etch evenly using traditional methods, requiring large amounts of etching solution and wasting costs. Traditional lamination equipment also struggles to precisely control pressure and temperature, easily leading to interlayer misalignment and air bubbles. While current lamination equipment uses online monitoring devices to track pressure, temperature, and displacement parameters in real time, triggering alarms and automatic adjustments to the equipment's operation if parameters deviate from preset ranges, continuous mass production is still impossible for long circuit boards, resulting in low production efficiency. Additionally, the large amounts of etching solution required for longer circuit boards further increase costs. Utility Model Content

In order to enhance the stability and transmission efficiency of the device, rings 10 are fixedly connected to the outer walls of multiple shafts 6 and shafts 9. A circulation mechanism 2 is fixedly connected to the rear side of the outer wall of the outer shell 1. The circulation mechanism 2 is used to etch the circuit board.

[0032] Specifically, a conveyor platform 3 is fixed to the inner wall of the outer casing 1 for conveying circuit boards. A protective shell 4 is fixed to the rear side of the outer wall of the conveyor platform 3 to ensure the safe operation of internal components. A motor 5 is fixed inside the protective shell 4 as a power source, and its output end is connected to a rotating shaft 6.

Then, a circulation mechanism 2 is fixed to the rear side of the outer wall of the outer casing 1 for etching circuit boards.

[0033] Please see the appendix Figure 2 - Appendix Figure 4 The circulation mechanism 2 includes a solution tank 201. The front part of the outer wall of the solution tank 201 is tightly connected to the outer shell 1 by a fixed connection to ensure its stability. Inside the solution tank 201, a water pump 202 is fixedly connected. The main function of the water pump 202 is to extract and transport the liquid in the solution tank 201. The output end of the water pump 202 is fixedly connected to a transmission pipe 203. The function of the transmission pipe 203 is to transport the liquid output by the water pump 202 to a designated location. The outer wall of the transmission pipe 203 is connected to multiple infusion pipes 204. These infusion pipes 204 are responsible for distributing the liquid to each nozzle 205. The bottom of the outer wall of the pipe 204 is connected to a nozzle 205. The nozzle 205 is used to spray the liquid evenly to the required area. A filter plate 206 is fixedly connected to the middle of the inner wall of the outer shell 1. The function of the filter plate 206 is to filter the circulating liquid to ensure its cleanliness. A circulation pump 207 is also fixedly connected to the bottom of the inner wall of the outer shell 1.

[0034] Specifically, the circulation mechanism 2 includes a solution tank 201, whose outer wall front side is fixedly connected to the outer shell 1 to ensure stability. A water pump 202 is fixed inside the solution tank 201 for extracting and transporting liquid. The output end of the water pump 202 is connected to a transmission pipe 203 to transport the liquid to a designated location.

A circulation pump 207 is fixed at the bottom to pump the filtered liquid back to the solution tank 201. Its output end is connected to a circulation pipe 208. A circulation groove 209 is opened on the top of the outer wall of the conveyor platform 3 so that the solution sprayed during etching flows into the filter plate 206 for filtration.

[0035] Please see the appendix Figure 1 - Appendix Figure 2 The conveyor platform 3 shown has a groove 11 on its rear side at the top. The bottom of the conveyor platform 3 is fixed with support columns 12 by a sturdy connection, which are evenly distributed at the four corners of the conveyor platform 3 to ensure the stability and load-bearing capacity of the conveyor platform 3. Each support column 12 is firmly fixed with a rubber pad 13 at its bottom. These rubber pads 13 can effectively reduce friction and vibration and provide better support. A sealing plate 14 is reliably fixed to the top of the outer wall of the groove 11. The function of the sealing plate 14 is to prevent external impurities from entering the interior of the groove 11. Similarly, a door 15 is installed on the top of the outer wall of the solution tank 201 by a fixed connection. The door 15 facilitates the operator to access and maintain the interior of the solution tank 201. A fixing plate 16 is also fixedly connected to the top of the outer wall of the door 15.

[0036] Specifically, the conveyor 3 has a groove 11 on the rear side of the top, and four support columns 12 are fixed at the bottom corners to ensure stable load bearing. The bottom of the support columns 12 is connected to rubber pads 13 to reduce friction and vibration. The top of the groove 11 is connected to a sealing plate 14 to prevent impurities from entering. Then, the solution tank 201 is fitted with a door 15 on the top for easy access and maintenance. The top of the door 15 is also fixed with a fixing plate 16.

[0037] Please see the appendix Figure 3 - Appendix Figure 5 Both fixing plates 16 are securely connected at the top of their outer walls and have handles 17 for easy gripping, facilitating operation and handling. The fixing plates 16 are threadedly connected at the top of their outer walls and have screws 18 to ensure the fixing plates 16 and the door 15 are securely fastened. The outer shell 1 has connecting plates 19 on both sides of its inner walls, which provide important structural support and connection. Both connecting plates 19 are threadedly connected at the top of their outer walls and have screws 20 for fastening and adjustment. Nuts 21 are threadedly connected to the screws 20 on their outer walls, allowing for easy rotation and adjustment. The protective shell 4 has a heat dissipation vent 22 on the rear side of its outer wall.

[0038] Specifically, each of the two fixed plates 16 has a handle 17 fixed to its top for easy operation and handling. The top area is connected by screws 18 to ensure that it is fixed to the door 15. The inner walls of the outer shell 1 are connected to the left and right sides of the connecting plates 19 for support and connection. The top of the connecting plates 19 is connected to the screws 20 for fastening and adjustment. The screws 20 are connected to the nuts 21 for easy rotation and adjustment. The protective shell 4 has a heat dissipation vent 22 on the rear side for heat dissipation.

[0039] Working principle: First, the circuit board to be etched is placed on the conveyor table 3. At this time, the motor 5 inside the protective shell 4 is started, which drives the rotating shaft 6 to rotate. Since the rear end of the rotating shaft 6 is connected to the small gear 7, the meshing of multiple small gears 7 causes multiple rotating shafts 6 to rotate simultaneously. The circuit board is placed on the rotating shaft 6 and moves through the ring 10 on the rotating shaft 6. When it is about to enter the interior of the shell 1, there are rotating shafts 9 on both sides of the inner wall of the shell 1. Since the large gear 8 at the rear end of the rotating shaft 9 meshes with the small gear 7 at the bottom, the rotating shaft 9 will also rotate. When the circuit board enters, the ring 10 on the rotating shaft 9 makes it enter more smoothly, achieving a smoother entry into the etching area. At the same time, since it relies on the drive device, multiple circuit boards can be placed continuously on the conveyor table 3 for processing.

[0040] When the circuit board enters the housing 1, the water pump 202 in the solution tank 201 is started. The water pump 202 draws out the solution from the solution tank 201 and transports it along the transmission pipe 203 to multiple infusion pipes 204 connected to its outer wall. Then, the nozzles 205 on the infusion pipes 204 spray the solution onto the circuit board to etch it. During the etching process, after etching is completed, the solution enters the bottom of the housing 1 through the circulation tank 209 opened in the conveyor 3. After being filtered by the filter plate 206, the circulation pump 207 is started to transport the filtered solution back to the solution tank 201 to complete the circulation. This saves costs and allows for large-scale and precise etching.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
