[0022] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0023] The embodiments of the present application provide an automatic pure water hole cleaning device, which solves the problem in the prior art that when cleaning PCB boards, a cleaning tank is usually used for vibration cleaning, and a robotic arm swings the PCB board up and down. This cleaning method can easily lead to inadequate cleaning of the inside of the PCB board holes, thereby causing the subsequent electroplating process to fail and reducing the quality of the PCB board.

[0024] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0025] The utility model discloses an automatic pure water hole cleaning device, according to the attached Figure 1-5As shown, it includes a cleaning pool 1 and a positioning frame 2 that is movably clamped on the cleaning pool 1, and the positioning frame 2 is provided with a clamping mechanism 3 for clamping the cleaning pool 1; the clamping mechanism 3 includes a sleeve 301 fixedly connected to the positioning frame 2 and a screw rod 302 threadedly connected to the sleeve 301, and a clamping block 303 is rotatably connected to the screw rod 302, and the clamping block 303 is slidably connected to the inside of the sleeve 301 and fits with the cleaning pool 1, and a lateral support rod 304 is fixedly connected to the clamping block 303, and the lateral support rod 304 is slidably connected to the sleeve 301.

[0026] The device is designed with a clamping mechanism 3, which makes it easy to clamp the positioning frame 2 on the cleaning pool 1 and limit the position. When clamping and limiting the positioning frame 2, the positioning frame 2 is first clamped with the cleaning pool 1 and moved horizontally to adjust the position. After adjusting to the target position, the screw rod 302 is rotated so that the screw rod 302 drives the clamping block 303 to move, so that the clamping block 303 clamps the side wall of the cleaning pool 1, forming a limit for the positioning frame 2;

[0027] When the clamping block 303 moves, the lateral support rod 304 is driven to move synchronously. The design of the lateral support rod 304 allows the clamping block 303 to be laterally supported, and has good stability.

[0028] A protective cover 4 is fixedly connected to the positioning frame 2, and an ultrasonic generator body 5 is movably inserted into the interior of the protective cover 4;

[0029] The device is provided with a protective cover 4 and an ultrasonic generator body 5 on a positioning frame 2. When cleaning a PCB board, pure water is added to the interior of the cleaning tank 1, and the ultrasonic generator body 5 is oscillated to form a pure water-wetting hole. The wetting effect is good, and the cleanliness of the hole is kept good, thereby achieving a good electroplating effect of the subsequent PCB board. The protective cover 4 is designed to provide protection for the ultrasonic generator body 5.

[0030] An L-shaped top plate 6 is provided on the top of the ultrasonic generator body 5, and a locking mechanism 7 is provided on the L-shaped top plate 6. The locking mechanism 7 includes a guide rail frame 701 fixedly connected to the L-shaped top plate 6, a slider 702 is slidably connected to the guide rail frame 701, a locking rod 703 is fixedly connected to the slider 702, a locking hole 201 is opened on the positioning frame 2, and the locking rod 703 is movably inserted into the locking hole 201. A spring 704 is fixedly connected between the guide rail frame 701 and the slider 702, and a pull rod 705 is fixedly connected to the slider 702.

[0031] The automatic pure water hole cleaning device is designed with an L-shaped top plate 6 and a locking mechanism 7, so that the ultrasonic generator body 5 can be easily disassembled and assembled inside the protective cover 4, thereby making the ultrasonic generator body 5 easy to disassemble, inspect and maintain regularly.

[0032] When installing the ultrasonic generator body 5, first align the ultrasonic generator body 5 with the inside of the protective cover 4 and snap it in. At the same time, pull the pull rod 705 to make the slider 702 and the locking rod 703 move as a whole and squeeze the spring 704 at the same time. When the ultrasonic generator body 5 is completely snapped into the inside of the protective cover 4, release the pull rod 705. At this time, the spring 704 stretches and pushes the slider 702 and the locking rod 703 to move, so that the locking rod 703 is inserted into the inside of the locking hole 201.

[0033] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention.
