It is characterized by complex process flow, high precision requirements, and continuously improving level of automation. It is a crucial link in the modern electronic manufacturing industry chain.

[0003] During the drilling process of circuit boards, the high-speed rotating drill bit generates intense friction with the board, which continuously peels off the surface material of the board, producing a large number of fine and dispersed drill chips. These chips are not only easily scattered by the airflow and adhere to various parts of the processing equipment, but may also block the chip discharge port or stick to the board surface, affecting subsequent processes. Cleaning them is very troublesome, usually requiring repeated blowing and wiping by a dust collector or manual cleaning, which greatly increases the maintenance workload and processing costs.

[0029] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0031] Example, according to Figures 1-4 ,like Figure 1As shown in the figure, the circuit board processing device provided by this utility model aims to solve the problem of drill chips flying and difficult cleaning in the existing drilling process. Its core is to realize the synchronous chip suction operation in the drilling process by setting up an elastic telescopic tube 702 component with adsorption and collection function, thereby greatly improving the processing cleanliness and automation level.

[0032] Specifically, it includes a three-axis gantry 1, and also includes: a support base 2, which is fixed on the moving part of the three-axis gantry 1; a drilling assembly 7, which is set on the support base 2; and a motor 3, which is fixed on one side of the support base 2. The drilling assembly 7 is driven by the motor 3 to perform drilling action. The drilling assembly 7 includes a rotating shaft 701 rotatably installed inside the support base 2. A drill rod 703 is fixedly installed on the lower part of the rotating shaft 701. Before processing, the control system controls the three-axis gantry 1 to move the drilling assembly 7 to the target drilling position according to a preset path. The motor 3 starts and drives the drilling assembly 7 installed on the support base 2 to rotate, driving the rotating shaft 701 to rotate at high speed, thereby realizing the high-speed drilling action of the drill rod 703.

[0033] The drill rod 703 is provided with an elastic telescopic tube 702 on the outside; the elastic telescopic tube 702 includes a fixed tube 7021 fixed to the lower part of the support base 2, and a lifting tube 7022 is slidably installed on the lower part of the fixed tube 7021 through a spring 7023. The fixed tube 7021 is used to connect to an external air intake source. At the same time, the structure of the elastic telescopic tube 702 starts to work. The fixed tube 7021 is fixed to the lower part of the support base 2 and establishes a negative pressure channel with the external air intake source through a connecting pipe. The lower part of the fixed tube 7021 is connected to the lifting tube 7022 slidably installed through a spring 7023. When the drill rod 703 moves downward with the rotating shaft 701 to approach the board surface for drilling, the lifting tube 7022 slides downward with the drill rod 703 under the action of the spring 7023 and finally fits against the board surface, realizing a local sealing and closing area between the drill rod 703 and the board surface.

[0034] During use, the three-axis gantry 1 moves the drill rod 703 to the designated position to perform a downward drilling action, and the lifting pipe 7022 is in close contact and sealed with the workpiece. The drill chips generated by the drill rod 703 are sucked out and collected by an external air source. As the drilling action continues, a large number of fine drill chips generated by the drill rod 703 are effectively restricted from scattering in this sealed area. Through the continuous negative pressure suction in the fixed pipe 7021, the chips are quickly sucked from the drilling point into the telescopic pipe channel and transported to the external collection device to prevent them from remaining on the board surface or falling into the gaps of the equipment.

[0035] Furthermore, thanks to its elastic telescopic structure, the 7022 lifting tube can automatically adapt to plates of varying thicknesses and heights, ensuring both sealing performance and chip collection efficiency. It maintains good contact even on non-horizontal surfaces or under conditions of slight displacement, enhancing the device's adaptability and stability. This highly integrated structure, with its excellent motion coordination, enables efficient and synchronous chip collection without compromising drilling accuracy, effectively reducing the frequency of manual cleaning and the risk of processing contamination.

[0036] In this embodiment, the sealing performance and operational visibility of the drilling assembly 7 are further optimized in terms of structure, and the stability and transmission accuracy of the system are improved in the construction of the three-axis moving mechanism.

[0037] Specifically, a rubber sleeve 7025 is fixedly connected to the lower part of the lifting pipe 7022 for sealing in contact with the plate. A transparent plate 7024 is embedded in the outer wall of the lifting pipe 7022 for observing the drilling progress. The three-axis gantry 1 includes a support frame 101. A longitudinal linear transmission platform 102 is fixedly installed on the upper part of the support frame 101. A vertical linear transmission platform 104 is fixedly installed on the moving part of the transverse linear transmission platform 103, which is fixedly installed on the moving part of the longitudinal linear transmission platform 102. The support base 2 is fixed on the moving part of the vertical linear transmission platform 104.

[0038] During equipment operation, the three-axis gantry 1 serves as the main motion platform, relying on its structural composition to achieve high-precision movement of the drilling assembly 7 in three-dimensional space.

[0039] The gantry includes a support frame 101 with a stable lower part, and a longitudinal linear transmission platform 102 fixed above the support frame 101 for linear movement along the X-axis. A transverse linear transmission platform 103 is installed on the moving part of the longitudinal transmission platform for transmission along the Y-axis. A vertical linear transmission platform 104 is installed on the moving part of the transverse platform to achieve vertical lifting along the Z-axis. The drilling assembly 7 is fixed to the moving part of the vertical platform by a support base 2, thereby enabling precise three-axis linkage positioning and drilling.

[0040] During the drilling process, the rubber sleeve 7025 located at the lower part of the lifting tube 7022 will first contact the circuit board surface when the drill bit approaches the board surface, forming a good fit and ensuring a sealed space to prevent drill cuttings from flying. At the same time, the outer wall of the lifting tube 7022 is provided with an embedded transparent plate 7024, which allows the operator or monitoring system to observe the drilling depth and processing status of the drill bit in real time, ensuring processing accuracy and operational safety. This structure not only enhances the functionality of the lifting tube 7022, but also improves the adaptability and intelligence level of the device in different application environments.

[0041] In this embodiment, by integrating the transmission component 4, the air pump 5, and the dual filter component 6 on the support base 2, a closed-loop system for efficient adsorption of drill cuttings and air purification during the drilling process is realized, further optimizing the working environment and the operational stability of the equipment.

[0042] Specifically, the upper part of the support base 2 is provided with a transmission assembly 4, which includes a double-layer rotating wheel 401 fixed to the output end of the motor 3. The double-layer rotating wheel 401 is driven by a first driven rotating wheel 402 fixed to the upper part of the rotating shaft 701. An air pump 5 is fixedly installed on the other side of the support base 2. A second driven rotating wheel 403 fixed to the outside of the drive shaft of the air pump 5 is driven by the double-layer rotating wheel 401. A filter assembly 6 is also provided on one side of the support base 2. The filter assembly 6 includes a first filter cartridge 601 inserted and installed on one side of the support base 2. The input end of the first filter cartridge 601 is connected to the fixed pipe 7021 through the first transmission pipe 602. The output end of the first filter cartridge 601 is fixedly connected to the input end of the air pump 5 through the second transmission pipe 603. The output end of the air pump 5 is screwed with a second filter cartridge 604, which performs a double filtration action.

[0043] Before drilling begins, the motor 3 on the support 2 is started, and a double-layer wheel 401 is fixedly installed on its output shaft. The double-layer wheel 401 is designed to drive power output in two directions at the same time.

[0044] Firstly, through belt drive, the double-layer rotating wheel 401 is connected to the first driven rotating wheel 402 installed on the upper part of the rotating shaft 701, thereby driving the rotating shaft 701 inside the drilling assembly 7 to rotate, realizing the high-speed drilling action of the drill rod 703.

[0045] Secondly, the double-layer wheel 401 on the other side is connected to the second driven wheel 403 outside the drive shaft of the air pump 5 on the other side of the support base 2 via a belt, forming a synchronous drive structure, thereby driving the air pump 5 to run during drilling operations.

[0046] After the air pump 5 is started, it generates a continuous negative pressure suction force. With the help of the chip suction channel formed by the fixed pipe 7021 and the external air suction source, the fine debris and dust generated during the drilling process are sucked into the first filter cartridge 601 set on the side of the support base 2 along the first transmission pipe 602. After the first filter cartridge 601 performs preliminary filtration of large particles, its output end is connected to the input end of the air pump 5 through the second transmission pipe 603, which delivers the relatively clean airflow into the air pump 5 for secondary suction treatment. Subsequently, the second filter cartridge 604 connected to the output end of the air pump 5 performs further high-precision filtration of the remaining fine particles to ensure that the discharged gas is clean and unpolluted, thereby achieving air quality control of the processing environment.

[0047] This dual filtration system is compact, operates synchronously, and is highly efficient. It not only improves the thoroughness of drill cuttings collection and prevents them from clogging pipelines or causing secondary pollution to the equipment, but also ensures the protection of the air pump and the cleanliness of the exhaust during long-term operation of the equipment. It has good industrial adaptability and reliability.

[0048] The working principle of this utility model is as follows:

[0049] By integrating a three-axis gantry 1, a drilling assembly 7, an elastic telescopic chip suction structure, a transmission assembly 4, an air pump 5, and a dual filtration system, efficient collaborative operation of drilling and synchronous chip suction is achieved.

[0050] At the start of processing, the three-axis gantry 1 moves the drilling assembly 7 to the target position according to the set path. The motor 3 drives the double-layer rotary wheel 401, which drives the rotating shaft 701 to rotate through the belt to realize the drilling action of the drill rod 703. At the same time, it drives the air pump 5 to start, forming a continuous suction.

[0051] The drill rod 703 is externally equipped with an elastic telescopic tube 702, which includes a fixed tube 7021 and a lifting tube 7022. The lower end of the lifting tube 7022 is provided with a rubber sleeve 7025 that fits against the surface of the plate to ensure a closed space. As the drill rod 703 moves down to drill, the drill cuttings are sucked into the fixed tube 7021 in the sealed area, enter the first filter cartridge 601 through the first transmission tube 602 for initial filtration, and then enter the air pump 5 through the second transmission tube 603. After being sucked in by the air pump 5, further filtration is completed in the second filter cartridge 604. Clean gas is discharged, and the drill cuttings are collected.

[0052] The 7022 lifting pipe has elastic compensation capabilities, which can adapt to plates of different thicknesses. It also features an external transparent observation window for easy monitoring of the drilling status. The three-axis transmission platform structure ensures accurate drilling positioning and stable operation. The entire system works in coordination to effectively improve drilling accuracy, processing cleanliness, and the level of automation.

[0053] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
