Description

Technical Field

[0001] This utility model relates to the field of PCB board processing technology, specifically a dust collection device for PCB board processing. Background Technology

[0002] Printed circuit boards (PCBs), as the core carrier of modern electronic devices, involve various mechanical processing steps in their manufacturing process, including drilling, milling, cutting, grinding, and grooving. During these processes, the high-speed rotation of the cutting tools acts on the copper-clad laminate material (mainly composed of epoxy resin, fiberglass cloth, and copper foil), inevitably generating a large amount of fine dust. This dust has a complex composition, primarily including epoxy resin particles, fiberglass fragments, and metallic copper powder.

[0003] Currently, the industry commonly uses dust collection devices to address dust issues during PCB manufacturing. Common configurations include installing nozzles on processing equipment and connecting them to standalone vacuum cleaners or centralized dust collection systems. However, existing technologies still have many shortcomings: for example, some nozzles have poor structural design and poor fit with the processing area, resulting in low dust collection efficiency and a large amount of dust escaping into the surrounding environment.

[0004] Therefore, there is an urgent need for a dust collection device for PCB board processing that is structurally sound, highly efficient, safe, and reliable. Utility Model Content

[0005] This utility model provides a dust collection device for PCB board processing. By connecting the nozzle to the dust collection pipe using an adapter, the position of the nozzle can be adjusted according to the actual use, thus solving the problem of poor fit with the processing area and low dust collection efficiency mentioned in the background art.

[0006] This utility model provides the following technical solution: A dust collection device for PCB board processing includes a dust cover and a dust collection pipe detachably connected to the dust cover. The dust collection pipe has a first connecting end and a second connecting end. The first connecting end is connected to a negative pressure component. One end of the second connecting end extending into the dust cover is connected to an adapter pipe. One end of the adapter pipe is fitted with a suction nozzle via a connector. When the negative pressure component is working, the suction nozzle is used to collect dust.

[0008] As a preferred technical solution of this utility model, the connector includes a ball with both ends through it. One end of the ball is fixedly connected to the adapter tube, and a rotating cavity is opened in one end of the suction nozzle. The other end of the ball extends into the rotating cavity.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0021] Example 1: Reference Figures 1-4 and Figure 6 A dust collection device for PCB board processing includes a dust cover 1 with an open bottom. During use, it covers the processing equipment, ensuring the internal suction nozzle 4 faces the processing position, thus reducing dust dispersion into the surrounding environment. Furthermore, the dust cover 1 is made of transparent acrylic, facilitating observation of the internal processing. It also includes a detachable suction pipe 2 connected to the dust cover 1. The suction pipe 2 has a first connecting end and a second connecting end. The first connecting end is connected to a negative pressure component, and the second connecting end extends into the dust cover 1, with an adapter pipe 3 inserted at one end. The negative pressure component is either a standalone vacuum cleaner or a central dust collection system. The top of the suction pipe 2 is connected to the suction end of the negative pressure component via a corrugated pipe. Preferably, a central dust collection system, model MJ-ZY-04, is used. One end of the adapter pipe 3 is fitted with a suction nozzle 4 via a connector. The nozzle 4 can be flat, cylindrical, or a ring-shaped tube. Flat nozzles are suitable for linear machining, arranged along the cutting path for wide coverage; cylindrical nozzles are suitable for single-point machining with concentrated suction; and ring-shaped nozzles can be designed to surround the tool, capturing dust at a large angle with high efficiency, making them the most common type in PCB manufacturing. Both the nozzle 4 and the suction pipe 2 are made of stainless steel, using metal pipes (such as galvanized steel pipes or stainless steel pipes) and are reliably grounded to prevent static electricity buildup that could cause a dust explosion. When the negative pressure assembly is working, the nozzle 4 is used to extract dust.

[0022] When in use, by connecting the nozzle 4 to the dust collection pipe 2 via the adapter pipe 3, on the one hand, the appropriate adapter pipe 3 can be selected according to the actual use situation, and on the other hand, the position of the nozzle 4 can be adjusted to increase the fit with the processing area, improve the dust collection efficiency, and reduce the dust from escaping into the surrounding environment.

[0023] Reference Figure 4 Multiple sealing rings 201 are provided on the outer wall of the second connecting end. There are two to six sealing rings 201, preferably four. All four sealing rings 201 abut against the inner wall of the adapter pipe 3. That is, when in use, the adapter pipe 3 is fitted onto the second connecting end. At this time, the second connecting end is located inside the adapter pipe 3, and the sealing rings 201 abut against the inner wall of the adapter pipe 3. On the one hand, this facilitates the installation and removal of the adapter pipe 3 and improves the flexibility of replacement. On the other hand, it can improve the sealing effect.

[0024] Reference Figures 2-4 Here, the connector includes a ball 301 extending through both ends. One end of the ball 301 is fixedly connected to the adapter tube 3. A rotating cavity is formed inside one end of the nozzle 4, and the other end of the ball 301 extends into the rotating cavity. A rubber pad is fixedly connected to the outer wall of the ball 301, and the outer wall of the rubber pad abuts against the inside of the rotating cavity. This not only increases damping but also improves the sealing effect. In use, by fixing the ball 301 to the adapter tube 3 and rotating the nozzle 4 to the ball 301, the angle of the nozzle 4 can be adjusted to increase the fit with the processing area and improve the dust collection effect.

[0025] Reference Figure 1 and Figure 2 A baffle is fixedly connected to the vacuum pipe 2, and a nut is threaded to one end of the vacuum pipe 2 that extends out of the dust cover 1. Both the baffle and the nut abut against the dust cover 1 through a sealing gasket. In use, by fixing the baffle to the vacuum pipe 2 and then threading the nut to the vacuum pipe 2, it is easy to install and remove the vacuum pipe 2, thus improving the usage effect.

[0026] Example 2: Reference Figure 5 Based on Embodiment 1, the connector is expanded. Here, the connector includes a universal bamboo tube 5, which is existing technology and can flexibly adjust the bending angle and maintain the adjusted state. One end of the universal bamboo tube 5 is fixedly connected to the adapter tube 3, and the nozzle 4 is fixedly connected to the other end of the universal bamboo tube 5. In this case, it is preferable to use a straight cylindrical structure for the nozzle 4. In use, by connecting the nozzle 4 to the adapter tube 3 using the universal bamboo tube 5, the position and angle of the nozzle 4 can be flexibly adjusted to improve the dust collection efficiency.
