Abstract
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 X-axis two-end drive 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

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] like Figure 1-5 As shown, a vertical rotation and oscillation device for wet circuit board manufacturing with X-axis two-end drive mode includes a work box 1, a fixture 2 for placing products, and a rotation and oscillation unit 3D. The work box 1 has an open front and an inlet / outlet 1-1 on the top. The fixture 2 enters the work box vertically through the inlet / outlet 1-1. The rotation and oscillation unit 3D includes a right drive mechanism 3D-1 and a left drive mechanism. The left drive mechanism and the right drive mechanism 3D-1 have the same structure, both including left and right pushing components, a second motor 3D-1-5, and a transmission shaft. 3D-1-7 and side gripper 3D-1-8; the drive shaft 3D-1-7 is horizontally rotatably inserted into the left or right side of the work box 1. One end of the drive shaft 3D-1-7 extends into the work box 1 and is connected to the side gripper 3D-1-8, and the other end is connected to the second motor 3D-1-5. The left and right pushing component is set outside the second motor 3D-1-5 and connected to the second motor 3D-1-5. The left and right pushing component drives the second motor 3D-1-5, the drive shaft 3D-1-7 and the side gripper 3D-1-8 to reciprocate left and right.
[0033] The fixture 2 is provided with a hollow mounting groove 2-1 for holding the product in place, so as to facilitate the processing of both sides of the product. The fixture can be rectangular.
[0034] For example, the left and right pushing assembly includes a first motor 3D-1-2, a turntable 3D-1-3, and a connecting rod 3D-1-4. The turntable 3D-1-3 rotates horizontally and is driven to rotate by the first motor 3D-1-2. One end of the connecting rod 3D-1-4 is connected to a second motor 3D-1-5, and the other end of the connecting rod 3D-1-4 is connected to the edge of the turntable 3D-1-3.
[0035] Specifically, the first motor 3D-1-2 is fixed on the mounting base 3D-1-1, and the mounting base 3D-1-1 is also provided with a guide rail 3D-1-6. The second motor 3D-1-5 is slidably mounted on the guide rail 3D-1-6.
[0036] More specifically, the second motor 3D-1-5 is also connected to a reducer, which is slidably mounted on the guide rail 3D-1-6. The shaft of the reducer is connected to the side gripper 3D-1-8, and the axis of the second motor 3D-1-5 is perpendicular to that of the reducer.
[0037] For example, the drive shaft 3D-1-7 includes a first connecting section 3D-1-7-1, a second connecting section 3D-1-7-2, a third connecting section 3D-1-7-3, a first spring 3D-1-7-4, and a limiting rod 3D-1-7-5; one end of the first connecting section 3D-1-7-1 is connected to a side gripper 3D-1-8, and the other end of the first connecting section 3D-1-7-1 is connected to the second connecting section 3D-1-7-2; the diameter of the second connecting section 3D-1-7-2 is smaller than the diameter of the first connecting section 3D-1-7-1. The second connecting segment 3D-1-7-2 is also slidably inserted inside the third connecting segment 3D-1-7-3; a limiting rod 3D-1-7-5 is provided on the side wall of the second connecting segment 3D-1-7-2 inserted inside the third connecting segment 3D-1-7-3, and a sliding hole 3D-1-7-6 is provided on the side wall of the third connecting segment 3D-1-7-3 for the limiting rod 3D-1-7-5 to pass through and move; a first spring 3D-1-7-4 is sleeved on the second connecting segment 3D-1-7-2 located outside the third connecting segment 3D-1-7-3.
[0038] When the fixture swings left and right, one motor pushes forward and the other motor retracts. There may be a slight asynchrony between the two motors. The transmission shaft structure can maintain a certain thrust through the first spring-assisted side gripper, so that the side gripper can clamp the front and back sides of the workpiece.
[0039] For example, the side gripper 3D-1-8 includes a gripper seat 3D-1-8-1, a fixed shaft 3D-1-8-2, a chuck 3D-1-8-3, and a second spring 3D-1-8-4. The gripper seat 3D-1-8-1 has a U-shaped cross-section. The left and right side walls of the gripper seat 3D-1-8-1 are provided with grooves 3D-1-8-1-1 for the chuck 3D-1-8-3 to pass through. The chuck 3D-1-8-3 has an L-shaped structure. The bent part of the chuck 3D-1-8-3 is rotatably connected to the groove 3D-1-8-1-1. The second spring 3D-1-8-4 is also provided between the rear side wall of the gripper seat 3D-1-8-1 and the chuck 3D-1-8-3.
[0040] The toilet gripper has a self-tightening structure. When tightening from left to right, the internal lever structure and the third spring of the side gripper will tighten the fixture.
[0041] Specifically, such as Figure 5 As shown, the jaws 3D-1-8-3 on the left and right side walls of the jaw holder 3D-1-8-1 are arranged alternately.
[0042] Working principle:
[0043] Before placing the fixture, pull the side jaws on both sides outward a little so that the fixture does not come into close contact with the side wall of the jaws when it is placed into the work box. At this time, the side jaws do not clamp tightly in front and behind, but the groove structure of the side jaws can still support the workpiece.
[0044] Then, the first motor drives the two side grippers to move towards each other, and the fixture is locked onto the side wall of the grippers and in close contact with them, thereby clamping the fixture tightly with the side grippers. After that, the first and second motors of the left and right drive mechanism are activated. The two second motors drive the fixture to rotate, while the two first motors push forward and retract backward, realizing the left and right swing of the fixture.
[0045] 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.
