Abstract
Description
Technical Field
[0001] This utility model relates to the field of circuit board printed mesh cleaning technology, specifically a circuit board printed mesh cleaning structure. Background Technology
[0002] Printed circuit board (PCB) is a core process in the electronics industry for manufacturing printed circuit boards. This process uses screen printing to precisely transfer conductive ink onto an insulating substrate, forming the circuit patterns that interconnect electronic components. The manufacturing process includes steps such as chemical etching, drilling and metallization, and multilayer lamination. It can produce single-sided, double-sided, and multilayer boards to meet the wiring requirements of different electronic devices. PCB printing is widely used in computers, communication equipment, home appliances, and military equipment, providing fixed support, electrical connections, and signal transmission functions for electronic components. It is an indispensable key component of modern electronic products.
[0003] In the existing technology of printed circuit board (PCB) production process, the problem of ink residue and clogging of the printing screen mesh is quite prominent. During the printing process, ink inevitably adheres to the inner wall of the printing screen mesh. Due to the certain viscosity of the ink, it sticks tightly after drying and is difficult to remove completely by conventional cleaning methods. The residual ink gradually accumulates, continuously reducing the effective aperture of the mesh and eventually causing clogging. This not only prevents the ink from passing through the mesh evenly and smoothly during printing, resulting in quality problems such as incomplete printed patterns and blurred edges on the PCB, but also forces frequent production interruptions for cleaning, greatly reducing overall production efficiency and increasing production costs and time losses. Therefore, we need a PCB printing screen cleaning structure. Utility Model Content
[0004] The purpose of this invention is to provide a circuit board printing mesh cleaning structure to solve the problems mentioned in the background art, such as the difficulty in cleaning ink residue in existing printing meshes, easy clogging, and the impact on printing quality and efficiency.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a circuit board printed mesh cleaning structure, including a movable platform, a movable frame movably connected to one side of the movable platform, an adjusting component movably connected to one side of the movable frame, an air jet component provided on one side of the movable platform, a printed mesh fixedly connected to the inner wall of the movable frame, the air jet component including an air pump, the air pump being fixedly located on one side of the movable frame, an air supply pipe fixedly connected to one end of the air pump, an air outlet pipe fixedly connected to one end of the air supply pipe, and an air jet head provided on the outer wall of the air outlet pipe.
[0006] Preferably, the air pump is connected to the air outlet pipe via an air supply pipe, with one end of the air supply pipe connected to the output end of the air pump and the other end of the air supply pipe connected to one end of the air outlet pipe.
[0007] Preferably, the exhaust pipe and the jet head form a fixed structure, and multiple jet heads are distributed at equal intervals on the exhaust pipe.
[0008] Preferably, the aperture of the jet nozzle is the same as the mesh diameter on the printing screen, and the jet nozzle is perpendicular to the printing screen.
[0009] Preferably, the adjusting component includes a gear, which is fixed to the outer wall of the air outlet pipe. A rack is meshed with one side of the gear, and a threaded sleeve is fixedly connected to one side of the rack. A threaded rod is threadedly connected to the inner wall of the threaded sleeve, and a sliding rod is slidably connected to the inner wall of the threaded sleeve. One end of the threaded rod is fixedly connected to the output shaft of the motor.
[0010] Preferably, the motor forms a threaded structure through a threaded rod and a threaded sleeve, with one end of the threaded rod connected to the output end of the motor and the outer wall of the threaded rod connected to the threaded sleeve.
[0011] Preferably, the threaded rod forms a sliding structure with the sliding rod through the threaded sleeve, and the outer diameter of the sliding rod matches the inner diameter of the threaded sleeve, and the outer wall of the sliding rod is fitted to the inner wall of the threaded sleeve.
[0012] Preferably, the rack and the air outlet pipe form a rotating structure through the gear, and one side of the rack meshes with one side of the gear, and the inner wall of the gear is connected to the outer wall of the air outlet pipe.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] In the scheme of this application:
[0015] 1. To address the problem of difficult-to-clean and easily clogged ink residue in printing screen meshes in existing technologies, which affects printing quality and efficiency, this application, by setting up an air pump, air supply pipe, air outlet pipe, and air jet head, enables the air pump to be started after printing. The air is then delivered to the air outlet pipe through the air supply pipe, and then precisely sprayed vertically into the printing screen meshes by the air jet head. This quickly and efficiently removes residual ink from the meshes, prevents mesh clogging, effectively ensures the quality of subsequent printing, greatly simplifies the cleaning process, and improves the overall work efficiency of circuit board printing.
[0016] 2. To address the problem that existing ink cleaning equipment struggles to thoroughly and effectively clean ink from different angles within the mesh openings, resulting in suboptimal cleaning performance, this application incorporates components such as a motor, threaded rod, threaded sleeve, rack, gear, and air outlet pipe. During the air blowing process, the motor drives the threaded rod to rotate, causing the threaded sleeve to slide along a sliding rod, which in turn moves the rack, drives the gear to rotate, and ultimately adjusts the air outlet pipe. This allows for precise air blowing from different angles into the mesh openings, comprehensively and thoroughly removing residual ink without any blind spots. This significantly improves the thoroughness and effectiveness of mesh cleaning, ensuring the quality of subsequent printing. Attached Figure Description

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.
[0023] This utility model embodiment provides a circuit board printed mesh cleaning structure, such as Figure 1 , Figure 2 and Figure 3As shown, the device includes a movable platform 1, a movable frame 2 movably connected to one side of the movable platform 1, an adjusting component 3 movably connected to one side of the movable frame 2, a jet assembly 4 installed on one side of the movable platform 1, a printing screen 5 fixedly connected to the inner wall of the movable frame 2, and a jet assembly 4 including an air pump 401 fixedly attached to one side of the movable frame 2. One end of the air pump 401 is fixedly connected to an air supply pipe 402, and one end of the air supply pipe 402 is fixedly connected to an air outlet pipe 403. A jet nozzle 404 is installed on the outer wall of the air outlet pipe 403. Firstly, through… The movable frame 2 moves on the movable table 1, causing the movable frame 2 to move down to the top of the circuit board. The material feeding and hanging components are activated, which allows printing on the circuit board. After printing is completed, the air pump 401 is activated, which outputs gas and transports it through the air supply pipe 402. The air supply pipe 402 transports the air into the air outlet pipe 403, where it is sprayed out by the jet nozzle 404. At the same time, the jet nozzle 404 is aligned with the mesh on the printing screen 5, which allows air to be blown vertically into the mesh of the printing screen 5.
[0024] Furthermore, such as Figure 3 As shown, the air pump 401 is connected to the air outlet pipe 403 through the air supply pipe 402. One end of the air supply pipe 402 is connected to the output end of the air pump 401, and the other end of the air supply pipe 402 is connected to one end of the air outlet pipe 403. Through the air pump 401, the air pump 401 can deliver gas to the air outlet pipe 403 by means of the air supply pipe 402.
[0025] Furthermore, such as Figure 3 As shown, the air outlet pipe 403 and the jet head 404 form a fixed structure, and multiple jet heads 404 are distributed at equal intervals on the air outlet pipe 403. By setting multiple jet heads 404, the cleaning of the printing screen 5 can be enhanced.
[0026] Furthermore, such as Figure 3 As shown, the aperture of the jet nozzle 404 is the same as the diameter of the mesh on the printing screen 5, and the jet nozzle 404 is perpendicular to the printing screen 5, which allows the jet nozzle 404 to blow air into the mesh on the printing screen 5 to clean the ink inside the mesh.
[0027] In a further preferred embodiment of this utility model, such as Figure 1 , Figure 2 and Figure 4As shown, the adjustment component 3 includes a gear 301, which is fixed to the outer wall of the air outlet pipe 403. A rack 302 is meshed with one side of the gear 301, and a threaded sleeve 303 is fixedly connected to one side of the rack 302. A threaded rod 304 is threadedly connected to the inner wall of the threaded sleeve 303, and a sliding rod 305 is slidably connected to the inner wall of the threaded sleeve 303. One end of the threaded rod 304 is fixedly connected to the output shaft of the motor 306. When the motor 306 is started, it drives the threaded rod 304 to rotate, which allows the threaded rod 304 to rotate through the threaded sleeve 303, which allows the threaded sleeve 303 to move, which allows the threaded sleeve 303 to slide along the sliding rod 305, which allows the threaded sleeve 303 to drive the rack 302 to move, which allows the rack 302 to drive the gear 301 to rotate, which allows the gear 301 to drive the air outlet pipe 403 to rotate and adjust, thereby cleaning the ink in the mesh from different angles.
[0028] Furthermore, such as Figure 4 As shown, the motor 306 forms a threaded structure with the threaded rod 304 and the threaded sleeve 303. One end of the threaded rod 304 is connected to the output end of the motor 306, and the outer wall of the threaded rod 304 is connected to the threaded sleeve 303. The motor 306 can drive the threaded rod 304 to rotate, and push the threaded sleeve 303 through the threaded sleeve 303.
[0029] Furthermore, such as Figure 4 As shown, the threaded rod 304 forms a sliding structure with the threaded sleeve 303 and the slide rod 305. The outer diameter of the slide rod 305 matches the inner diameter of the threaded sleeve 303, and the outer wall of the slide rod 305 is fitted to the inner wall of the threaded sleeve 303. Through the threaded sleeve 303, the threaded sleeve 303 can slide along the outer wall of the slide rod 305 under the drive of the threaded rod 304.
[0030] Furthermore, such as Figure 4 As shown, the rack 302 forms a rotating structure with the air outlet pipe 403 through the gear 301, and one side of the rack 302 meshes with one side of the gear 301, and the inner wall of the gear 301 is connected to the outer wall of the air outlet pipe 403. Through the rack 302, the rack 302 can move to drive the gear 301 to rotate, and the gear 301 can drive the air outlet pipe 403 to rotate.
[0031] Working principle: For printing on the circuit board, the movable frame 2 moves on the movable table 1, causing it to descend to the top of the circuit board. This activates the material feeding and hanging components, allowing printing to proceed. After printing, the air pump 401 is activated, outputting gas which is transported through the air supply pipe 402 to the air outlet pipe 403. The air is then ejected from the nozzle 404, which is aligned with the mesh of the printing screen 5, allowing the printing process to proceed vertically towards the screen. 5. Air is blown into the mesh. During the blowing process, the motor 306 is started, which drives the threaded rod 304 to rotate. The threaded rod 304 rotates through the threaded sleeve 303, which moves the threaded sleeve 303. The threaded sleeve 303 slides along the slide rod 305, which drives the rack 302 to move. The rack 302 drives the gear 301 to rotate, which drives the air outlet pipe 403 to rotate and adjust, thereby cleaning the ink in the mesh from different angles.
