Abstract
Description
Technical Field
[0001] This utility model belongs to the field of circuit board processing technology, specifically a dust removal device for circuit board cutting. Background Technology
[0002] In the circuit board manufacturing process, the cutting process is an indispensable step. During this process, the friction between the high-speed rotating cutting tool and the circuit board material inevitably generates a large amount of fine dust. If these dust particles are released directly into the air without treatment, they will cause serious pollution to the workshop environment and also pose a potential threat to the respiratory system of operators.
[0003] The commonly used dust removal method is to install an exhaust fan above the cutting machine to collect dust. However, this method has obvious drawbacks: firstly, the single suction action is insufficient to create an effective dust-capturing airflow, resulting in low dust removal efficiency; secondly, high-speed airflow can easily re-entrain settled dust, causing secondary pollution and exacerbating the deterioration of the working environment. Therefore, developing a high-efficiency and reliable dust removal device for circuit board cutting is particularly necessary. Utility Model Content
[0004] To address the problems mentioned in the background art, this utility model provides the following technical solution: a dust removal device for circuit board cutting, including a cutting blade, an outer cover for the cutting blade, an air duct on the outer cover, the air duct having a front section and a rear section, a pipe detachably connected between the front section and the rear section, a filter screen inside the rear section, and a fan connected to the rear section.
[0005] Preferably, the upper end of the pipe is fixedly connected to a plug-in block, and a plug-in groove is provided on the duct, with the plug-in block cooperating with the plug-in groove.
[0006] Preferably, the front segment and the rear segment are connected by a connecting block.
[0007] Preferably, a baffle is installed at the lower end of the outer cover, and a roller is rotatably installed at the lower end of the baffle. The rotation direction of the roller is the same as the rotation direction of the cutting blade.
[0008] Preferably, a slider is fixed to the side of the baffle, and a groove is provided on the lower inner wall of the outer cover. The slider is inserted into the groove and can slide along the groove.
[0009] Preferably, the lower end of the outer cover has a vertical section, and a groove is formed on the inner wall of the vertical section.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] When this device is in use, the outer cover covers the cutting blade. While the cutting blade is cutting the circuit board, the fan is also running. The fan draws air through the air duct, thereby sucking up the debris generated during the cutting process. This not only improves dust removal efficiency but also prevents dust from other locations from being stirred up. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0017] Depend on Figure 1-2 The present invention discloses a dust removal device for circuit board cutting, including a cutting blade 1, an outer cover 2 is provided on the outside of the cutting blade 1, and an air duct 5 is provided on the outer cover 2. The air duct 5 has a front section and a rear section, and a pipe 6 is detachably connected between the front section and the rear section. A filter screen 8 is provided in the rear section, and a fan is connected to the rear section.
[0018] When this device is in use, the outer cover 2 covers the cutting blade 1. While the cutting blade 1 is cutting the circuit board, the fan is also running. The fan draws air through the air duct 5, thereby sucking up the debris generated during the cutting process of the cutting blade 1. This not only improves the dust removal efficiency, but also prevents dust from other locations from being stirred up.
[0019] The upper end of the pipe 6 is fixedly connected to a plug block 7, and a plug groove is provided on the air duct 5, with the plug block 7 cooperating with the plug groove.
[0020] The combination of the plug-in block 7 and the plug-in slot allows users to easily disassemble or install the pipe 6 by plugging and unplugging. In practice, a sealing plate can also be installed in the plug-in slot to increase the sealing performance.
[0021] The front and rear sections are connected by a connecting block so that the duct 5 remains a single unit after the pipe 6 is removed.
[0022] A baffle 4 is installed at the lower end of the outer cover 2. A roller 10 is rotatably installed at the lower end of the baffle 4. The rotation direction of the roller 10 is the same as the rotation direction of the cutting blade 1, so as to facilitate the left and right sliding of the baffle 4.
[0023] A slider 9 is fixed to the side of the baffle 4. A groove 3 is provided on the lower inner wall of the outer cover 2. The slider 9 is inserted into the groove 3 and can slide along the groove 3.
[0024] The lower end of the outer cover 2 has a vertical section, and the groove 3 is formed on the inner wall of the vertical section.
[0025] The baffle 4 can move up and down, thereby minimizing the splashing of debris during the cutting process and allowing for more comprehensive suction of the debris.
