Description

Technical Field

[0001] This application relates to the field of flexible board manufacturing, and in particular to etching equipment for a flexible board DES production line. Background Technology

[0002] The DES line is the core production line in printed circuit board (PCB) manufacturing, encompassing developing, etching, and stripping. With the development of the electronics industry, the requirements for its quality and efficiency are increasingly stringent. Its stable operation directly affects PCB yield, production costs, and production cycle, thus impacting the performance and quality of electronic devices.

[0003] In existing technologies, etching equipment typically has baffles at both ends to ensure normal circuit board production and prevent chemicals from the previous process from entering the next. However, the presence of these baffles also blocks the entry of cleaning agents, leading to inadequate maintenance, affecting subsequent production and increasing circuit board defects. Furthermore, it causes chemical residue buildup, resulting in the scrapping of equipment components. To ensure the production quality of the DES line, etching equipment undergoes maintenance and cleaning. Simple chemical changes are performed 1-2 times daily, while comprehensive cleaning and maintenance are conducted every 7-10 days. The current standard practice for cleaning the roller conveyor mechanism involves operators manually disassembling the baffle and roller conveyor devices for soaking and cleaning. However, this method has significant drawbacks. Manual disassembly and soaking are not only cumbersome but also greatly reduce maintenance efficiency.

[0004] Therefore, developing an etching device for a flexible board DES production line to solve the technical problems of low maintenance efficiency and cumbersome cleaning in the existing technology has become an important issue that urgently needs to be addressed. Utility Model Content

[0005] To address the technical problems of low maintenance efficiency and cumbersome cleaning in existing etching equipment, this application provides an etching device for a flexible board DES production line.

[0006] An etching device for a flexible board DES production line includes an etching chamber body and a cleaning chamber body connected to the etching chamber body. The etching chamber body contains a first roller conveying mechanism and a first spraying device for spraying etching solution onto the flexible board on the first roller conveying mechanism. The first roller conveying mechanism includes a plurality of first drive rollers arranged in an array. The etching chamber body has an inlet and an outlet at both ends. The outlet is equipped with a baffle plate device, which has a through hole for the flexible board to pass through. The flexible board enters the cleaning chamber body through the through hole. A cleaning assembly is installed inside the baffle plate device, and the cleaning assembly is used to clean the first drive rollers located at the baffle plate device.

[0007] By adopting the above technical solution, a cleaning component is installed inside the baffle device at the discharge port of the etching box in the etching equipment of the flexible board DES production line. This component can clean the first drive roller located at the baffle device, thus promptly removing impurities and chemical residues from the first drive roller, keeping it clean, and preventing contamination of the flexible board by impurities and chemical residues. This ensures the normal operation of the etching and cleaning processes and improves the production quality of the flexible board. At the same time, the cleaning component can perform cleaning during equipment operation, eliminating the need for frequent disassembly of the baffle device and the first drive roller, improving maintenance efficiency and reducing equipment downtime.

[0008] Furthermore, the water baffle device includes a first baffle and a second baffle, the through hole passes through the first baffle and the second baffle, and the cleaning component is disposed between the first baffle and the second baffle.

[0009] By adopting the above technical solution, the baffle device consists of a first baffle and a second baffle. A through hole passes through the first baffle and the second baffle, allowing the flexible plate to pass smoothly into the cleaning tank body. The cleaning component is placed between the first baffle and the second baffle. This structural design allows the cleaning component to accurately clean the first drive roller at the baffle device, avoiding waste of cleaning agent. At the same time, it can effectively prevent the previous process solution from entering the next process, ensuring the normal operation of the production line. Moreover, the cleaning effect is better, which can reduce the maintenance time and improve maintenance efficiency.

[0010] Furthermore, the cleaning assembly includes multiple long-tube nozzles, the nozzles of which face the first drive roller inside the baffle device. A cleaning agent storage tank is provided outside the etching box body, and the cleaning agent storage tank is connected to the long-tube nozzles via a constant pressure pump.

[0011] By adopting the above technical solution, during the maintenance of etching equipment, the cleaning agent in the cleaning agent storage tank can be directly rinsed through the long tube nozzle of the water baffle device under the action of a constant pressure pump, which can effectively clean the impurities on the transmission roller. The DES cleaning line does not need to be stopped or unnecessary disassembly is required, which not only improves maintenance efficiency and reduces the maintenance time, but also reduces the damage and scrapping of equipment parts caused by disassembly, and improves the maintenance effect, reducing the occurrence of circuit board defects in production.

[0012] Furthermore, the bottom of the baffle device is provided with a drain port, which is connected to the cleaning tank body. The waste liquid after rinsing by the long-tube nozzle is discharged through the drain port into the collection tank inside the cleaning tank body.

[0013] By adopting the above technical solution, a drain port is set at the bottom of the baffle device and connected to the cleaning tank body. This allows the waste liquid after the long-tube nozzle washes the first drive roller to be smoothly discharged into the collection tank inside the cleaning tank body. This avoids the accumulation of waste liquid in the baffle device, preventing corrosion and damage to the equipment due to waste liquid residue, and extending the service life of the equipment. At the same time, collecting the waste liquid centrally in the cleaning tank body facilitates subsequent unified treatment of the waste liquid, reduces equipment costs and floor space, and improves the overall practicality and economy of the equipment.

[0014] Furthermore, the first spraying device includes a first spray pipe and a second spray pipe located at the upper and lower ends of the first roller conveying mechanism, and both the first spray pipe and the second spray pipe are provided with a plurality of nozzles facing the first roller conveying mechanism.

[0015] By adopting the above technical solution, the first spray pipe and the second spray pipe of the first spraying device are located at the upper and lower ends of the first roller conveying mechanism, and each is equipped with multiple nozzles facing the conveying mechanism. This allows the etching liquid to be sprayed onto the flexible plate on the first roller conveying mechanism from both the upper and lower directions, so that the etching liquid can be more evenly covered on the surface of the flexible plate, thereby improving the etching effect and making the etching of the flexible plate more thorough and comprehensive, which helps to improve the processing quality and production efficiency of the flexible plate.

[0016] Furthermore, the cleaning tank body is provided with a second roller conveying mechanism and a second spraying device for spraying clean water onto the flexible plate on the second roller conveying mechanism. The second roller conveying mechanism includes a plurality of second drive rollers arranged in a row.

[0017] By adopting the above technical solution, the second roller conveying mechanism inside the cleaning box can transport the flexible plate, and the second spraying device can spray clean water onto the flexible plate to effectively remove residual etching solution and impurities on the flexible plate, ensuring the cleanliness of the flexible plate, thereby improving the cleaning quality and efficiency of the flexible plate and meeting the requirements of the etching equipment of the flexible plate DES production line for the cleaning of the flexible plate.

[0018] Furthermore, the second spraying device includes a third spray pipe and a fourth spray pipe located at the upper and lower ends of the second roller conveying mechanism, and both the third spray pipe and the fourth spray pipe are provided with multiple nozzles facing the second roller conveying mechanism.

[0019] By adopting the above technical solution, the third and fourth spray pipes of the second spray device are located at the upper and lower ends of the second roller conveying mechanism, respectively, and each is equipped with multiple nozzles facing the second roller conveying mechanism. This allows for simultaneous spraying of clean water onto the flexible plate on the second roller conveying mechanism, ensuring that both the upper and lower surfaces of the flexible plate are fully in contact with the clean water. This improves the comprehensiveness and uniformity of the cleaning, effectively removes impurities and residual etching solution from the surface of the flexible plate, and guarantees the cleaning effect and quality of the flexible plate.

[0020] Furthermore, the etching chamber body also includes an etching solution circulation pump, which is disposed on the top of the etching chamber body. The etching solution circulation pump is connected to the first spray pipe and the second spray pipe respectively, and is used to provide etching solution to the first spray pipe and the second spray pipe.

[0021] By adopting the above technical solution, the etching solution circulation pump set on the top of the etching box body is connected to the first spray pipe and the second spray pipe, which can continuously and stably supply etching solution to the first spray pipe and the second spray pipe. This allows the etching solution to be sprayed evenly and sufficiently onto the flexible plate on the first roller conveying mechanism, ensuring that the flexible plate can fully contact the etching solution, thereby effectively improving the etching effect and etching efficiency of the flexible plate and reducing etching quality problems caused by insufficient or uneven supply of etching solution during the etching process.

[0022] Furthermore, the first and second drive rollers are made of corrosion-resistant materials.

[0023] By adopting the above technical solution, the first and second drive rollers are made of corrosion-resistant materials, which can prevent them from being corroded by etching solutions, cleaning solutions, etc. during etching and cleaning processes, extend the service life of the drive rollers, reduce equipment maintenance costs and replacement frequency, ensure the stable operation of the etching equipment in the flexible board DES production line, thereby ensuring the continuity of production and product quality, and improving production efficiency.

[0024] In summary, this application has at least the following beneficial technical effects: by incorporating a cleaning component, a constant pressure pump, and a cleaning agent storage tank inside the baffle device, this application achieves the effects of improving maintenance efficiency and reducing the maintenance time required. The DES production line does not need to be stopped; the first drive roller at the baffle device can be cleaned simply by turning on the constant pressure pump, avoiding manual disassembly and improving maintenance efficiency.
