Description

Technical Field

[0001] This utility model relates to the technical field of circuit board cutting and processing equipment, and in particular to a high-speed circuit board cutting platform with electrostatic dust removal function. Background Technology

[0002] In printed circuit board (PCB) manufacturing processes, high-speed cutting platforms are widely used for precision depaneling, trimming, and forming. However, during actual cutting, due to the fineness of the materials and the high cutting speed, a large amount of micro-dust is easily generated around the cutting path. If this micro-dust is not removed in time, it can easily accumulate in the circuit area, causing circuit contamination, short circuit hazards, or reduced coating adhesion, affecting product yield. Traditional dust removal methods mainly use fixed suction ports, relying on negative airflow for adsorption, which is difficult to cover the entire cutting area. Especially for mobile cutting platforms, the dust removal efficiency is insufficient, the lag is obvious, and it is impossible to accurately approach the source of micro-dust. Therefore, there is an urgent need for a high-efficiency dust removal structure that is linked to the cutting head, has a compact structure, and can accurately act on the cutting path area. Utility Model Content

[0003] The purpose of this invention is to provide a high-speed circuit board cutting platform with electrostatic dust removal function to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A high-speed circuit board cutting platform with electrostatic dust removal function includes a base, a cutting worktable, a cutting slide rail mechanism, a cutting head module, and an electrostatic dust removal assembly. The cutting worktable is fixedly mounted on the base. The cutting slide rail mechanism is positioned above the cutting worktable and extends along the length of the circuit board. The cutting head module is slidably mounted on the cutting slide rail mechanism for high-speed cutting operations on the circuit board. The electrostatic dust removal assembly is fixedly mounted on the lower side of the tail of the cutting head module. The electrostatic dust removal assembly includes a plasma electrostatic generator, an adsorption guide hood, and a dust collection channel. The opening of the adsorption guide hood faces the cutting path area on the surface of the circuit board. The dust collection channel is connected to an external dust removal host. The plasma electrostatic generator releases a high-voltage ion current into the internal space of the adsorption guide hood during the cutting process, forming a micro-dust adsorption field. This allows fine dust particles generated behind the cutting head to be simultaneously adsorbed and guided into the dust removal host through the dust collection channel.

[0006] Preferably, the adsorption guide hood is a semi-enclosed inverted U-shaped structure with a diversion inclined plate at the front end and inwardly tapering guide arc walls on both sides, which are used to limit the diffusion of the high-pressure ion field and concentrate the airflow direction.

[0007] Preferably, the plasma electrostatic generator is connected to the cutting head module via a conductive bracket and is driven by an independent power supply, and is turned on and off synchronously with the cutting main control system.

[0008] Preferably, the electrostatic dust removal component and the cutting head module are integrated into one structure, and the cutting path is covered and dusted in real time throughout the entire process of the cutting head moving.

[0009] Preferably, the bottom edge of the adsorption guide cover is 3mm to 8mm away from the surface of the circuit board, forming a negative pressure adsorption gap.

[0010] Preferably, the dust collection channel is made of high-temperature resistant soft conduit and is equipped with a follow-up traction chain to adapt to the movement stroke of the cutting head.

[0011] Preferably, the dust removal host is equipped with a negative pressure fan, a particulate filter and an electrostatic dust collection box, and the particle collection accuracy reaches the PM5 level.

[0012] Preferably, an auxiliary pressure plate assembly is provided in front of the cutting head module to press the edge of the circuit board before cutting, preventing dust accumulation and obstruction.

[0013] Preferably, the plasma electrostatic generator has a modular structure, including a high-voltage ion needle assembly, a shielding cover, and a control circuit board, which can be replaced and maintained as a whole.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This high-speed circuit board cutting platform with electrostatic dust removal function features a compact plasma electrostatic adsorption module that is close to the source of micro-dust generation. Its dust removal synchronization is higher than that of traditional air intake structures, effectively preventing dust diffusion and deposition.

[0016] 2.

[0023] 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.

[0024] Please see Figures 1 to 5 As shown, this utility model provides a high-speed cutting platform for circuit boards with electrostatic dust removal function, which is suitable for high-precision and high-cleanliness cutting operations such as board separation, trimming or grooving of precision electronic materials such as PCBs during the production process.

[0025] The platform includes a base (1), a cutting worktable (2), a cutting slide rail mechanism (3), a cutting head module (4), and an electrostatic dust removal assembly (5). The base is a rectangular cast aluminum or steel structure with a thickness ≥20mm, used to stably support the entire platform system. The cutting worktable is a vacuum adsorption carrier plate with multiple sets of negative pressure holes for temporarily fixing the circuit board (L) to prevent displacement during processing. The slide rail mechanism (3) is a linear slide rail assembly, using servo drive or ball screw structure, arranged along the length of the circuit board, and has a repeatability accuracy within 0.05mm to ensure cutting accuracy.

[0026] The cutting head module (4) is a high-speed rotating cutting device with a built-in spindle motor, Z-axis adjustment module, and pneumatic auxiliary mechanism, and the cutting speed can reach 30,000 rpm. The lower part of its tail integrates an electrostatic dust removal component (5), which mainly includes a plasma electrostatic generator (51), an adsorption guide hood (52), and a dust collection channel (53). The plasma electrostatic generator adopts a rod-shaped or needle array structure, including a high-voltage ion needle group, a control circuit board, and a metal shield. It is installed inside the lower housing of the cutting head through a conductive bracket (54), driven by an independent high-voltage power supply module, and connected to the main control system through a signal line to realize synchronous start and stop with the cutting action. The plasma generator continuously releases charged ion flow, forming a high-intensity local electrostatic field in the adsorption guide hood (52), which significantly improves the adsorption capacity of microparticles.

[0027] The adsorption guide hood (52) is an inverted U-shaped semi-enclosed structure made of lightweight aluminum alloy or high-temperature resistant ABS. A diversion ramp (521) is provided at the front end to guide the high-speed airflow close to the surface of the cutting path (P). Guide arc walls (522) are provided on both sides to focus the airflow path and prevent ion field diffusion. The distance between the bottom surface of the hood and the surface of the circuit board is controlled between 3 and 8 mm. An adsorption window is formed through the negative pressure zone to improve the efficiency of synchronous dust collection.

[0028] The dust collection channel (53) is a high-temperature resistant soft conduit (such as a silicone tube or PU hose), connecting the tail of the adsorption hood to the air inlet of the external dust collector (6). A follow-up traction chain (55) is installed on the outside of the channel, which can flexibly follow the cutting head throughout its movement, preventing excessive pulling or interference with other mechanisms. The dust collector (6) is equipped with a negative pressure fan, primary filter cotton, particulate filter screen and electrostatic dust collection box, which can classify and collect PM5 and smaller particles, with a dust collection efficiency of >95%.

[0029] To prevent dust from accumulating on the edge of the workpiece before cutting, this utility model also provides an auxiliary pressure plate assembly (7) at the front end of the cutting head module (4). The pressure plate is made of soft conductive silicone material and is installed on an elastic bracket. It can lightly press the edge of the circuit board before cutting to make the surface flat and make good contact, further preventing dust from being brought into the processed area.

[0030] The entire dust removal system is centrally controlled by the main control board, implementing the working logic of "cutting start-up - simultaneous activation of dust removal components - automatic shutdown of dust removal power at the end of cutting". In actual use, this structure can not only achieve simultaneous removal of dust along the cutting path, but also significantly reduce the temperature rise in the cutting area, improving processing quality and equipment lifespan.

[0031] Compared with traditional fixed air intakes, this utility model integrates the dust removal component with the cutting module into one unit, avoiding the problems of "dust suction lag" and "blind spots in cleaning", achieving synchronous dust removal throughout the entire process. The structure is more compact, the system response is faster, and it is suitable for various high-end circuit board manufacturing scenarios such as SMT front-end processes, FPC / rigid board composite board cutting, and automated unloading. It has excellent technical practicality and promotional value.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
