Description

Technical Field

[0001] This utility model belongs to the field of circuit board processing technology, and in particular relates to a vertical rotation and swing device for wet circuit board processing with an edge-driven mode. Background Technology

[0002] The manufacturing process of circuit boards is much more complex than that of most products. Industry professionals generally refer to processes that are more closely related to water as wet processes, and processes that are less related to water as dry processes. Wet processes can be further divided into subtractive wet processes, additive wet processes, and cleaning wet processes. Subtractive wet processes, such as developing, etching, and film removal, remove material from the work-in-process using wet methods. Additive wet processes can be divided into chemical plating and electroplating. For example, immersion copper and immersion nickel are chemical plating, while electroplating copper and electroplating tin-lead are electroplating. Cleaning wet processes include water washing and DI water washing.

[0003] Currently, most traditional wet subtractive manufacturing processes, such as developing, etching, stripping, and chemical cleaning, are horizontal processes. Therefore, they inevitably involve a pooling effect, which refers to the phenomenon caused by the accumulation of chemicals such as etchants and developers on the surface of the PCB during spraying. This pooling effect hinders the uniformity of the chemical reaction, causing the lower surface of the workpiece to react faster than the upper surface, and the central area to react faster than the surrounding areas.

[0004] Currently, traditional additive wet processes, whether chemical plating or electroplating, all employ a static processing mode. The risk of static processing is that air bubbles can easily get trapped inside the holes, causing processing defects, especially in products with many small holes and micro-holes. As electronic products become increasingly miniaturized, circuit boards with micro-hole designs are becoming more and more common. In many cases, defects caused by air bubbles inside micro-holes can render an entire circuit board unusable due to a single void in a hole.

[0005] Moreover, both traditional subtractive wet processing and additive wet processing have relatively long production lines, ranging from tens to hundreds of meters in length. This makes them difficult for some R&D-oriented, self-use, or small-to-medium-sized OEM companies to use due to their large footprint. The sheer size of traditional wet processing equipment inevitably leads to other problems, such as high start-up costs, inconvenience for intermittent production, and increased environmental pollution, posing health risks to employees and the surrounding environment, thus increasing the company's waste treatment costs.

[0006] In addition, the existing production equipment has a slow turnover rate of chemical reaction interface solutions, resulting in low processing efficiency. Utility Model Content

[0036] Specifically, a speed reducer can also be installed on the slide 3A-4-2, the shaft of the motor 3A-4-3 is connected to the speed reducer, the shaft of the speed reducer is connected to the transmission wheel, and the axes of the motor and the speed reducer are perpendicular.

[0037] Specifically, the input mechanism 3A-1 and the output mechanism 3A-2 have the same structure, such as... Figure 5 As shown, each includes a chain support frame 3A-1-1, a chain 3A-1-2, a driving gear 3A-1-3, and a driven gear 3A-1-4.

[0039] More specifically, the lifting mechanism 3A-3 includes a bracket 3A-3-1, a first electric cylinder 3A-3-2, a chain rod 3A-3-3, and an insert rod 3A-3-4; the top of the bracket 3A-3-1 is provided with a first electric cylinder 3A-3-2 that extends and retracts in the vertical direction, the end of the extension rod of the first electric cylinder 3A-3-2 is hinged to the upper end of the chain rod, and the lower end of the chain rod is provided with an insert rod 3A-3-4; the chain support frame 3A-1-1 is provided with an elongated hole 3A-1-5 extending along the length of the chain support frame 3A-1-1 near the drive gear 3A-1-3, and the insert rod 3A-3-4 is slidably inserted into the elongated hole 3A-1-5; one end of the chain support frame 3A-1-1 with the driven gear 3A-1-4 is supported by a support 3A-1-6.

[0041] Specifically, in order not to hinder the jig's forward and backward movement, the inner side of the guide plate is arc-shaped, and the radius of the arc is larger than the radius of the jig, so that when the jig moves to the transmission wheel, the guide plate and the jig are offset from each other.

[0042] Working principle:

[0043] When using this device, the fixture is first placed on the chain of the input mechanism. The teeth of the chain match the edge of the fixture. The chain moves, causing the fixture to move along the chain. Simultaneously, the lifting mechanism raises the chain at a certain angle so that the fixture can engage between the upper and lower drive wheels. The fixture enters the work box, where a guide plate prevents it from tipping over until it rotates to the drive wheels and engages with them. Then, the chain is lowered, and the fixture disengages from the chain. Driven by a motor, the upper and lower drive wheels rotate the fixture clockwise or counterclockwise. At the same time, a second electric cylinder drives the fixture to swing back and forth. After processing, only the upper drive wheel is rotated to disengage the fixture from the upper and lower drive wheels. The fixture then moves to the chain of the output mechanism and is conveyed out of the work box by the chain.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
