Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, and in particular to a device for cleaning a faulty circuit board before repair. Background Technology

[0002] Circuit boards, also known as printed circuit boards, are widely used in modern communications, aerospace, computers, and other intelligent technology fields. They play a crucial role in artificial intelligence and other high-end cutting-edge technologies. Since various working environments and improper operation can damage circuit boards, they must be repaired. Before repairing a circuit board, it is necessary to remove dust and oil stains from it.

[0003] Utility model disclosure CN221790380U discloses a clamp and a cleaning device for circuit boards, relating to the field of circuit board processing technology. The device includes an ultrasonic cleaner. The ultrasonic cleaner has a mesh plate at its bottom, with side rods fixed to both ends of the mesh plate's sidewalls. L-shaped plates are provided on both sides of the ultrasonic cleaner. Circuit boards are placed vertically, with their ends inserted into clamping plates at both ends. The clamping plates form a clamp through the elastic force of spring push rods, thus holding the circuit boards. Rotation of the screw presses down on the pressure plate. After passing through the pressure groove, the pressure plate presses down on the slider in the slide rail, thus keeping the circuit boards held vertical by the spring push rods and clamping plates. This ensures that when the mesh plate enters the ultrasonic cleaner, adjacent circuit boards maintain a distance, preventing collisions.

[0004] When the device disclosed in the above utility model changes the spacing between adjacent circuit boards, it is necessary to manually adjust the position of several sliders on both sides in the corresponding slide rails. This operation is cumbersome and it is difficult to keep the movement distance of each slider uniform. Summary of the Invention

[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.

[0017] Reference Figure 1-4 A device for cleaning a faulty circuit board before repair includes an ultrasonic cleaner 1. A mesh basket 2 is placed inside the ultrasonic cleaner 1. A clamping mechanism 3 is provided on the upper part of the mesh basket 2. Two movable plates 4 are drivenly connected to the clamping mechanism 3. The movable plates 4 are located inside the mesh basket 2 and are controlled by the clamping mechanism 3 to move towards each other. Several movable rods 5 are provided on the side of the two movable plates 4 that are close to each other. The bottom of each of the movable rods 5 is connected to a clamping plate 6. The clamping plates 6 on the two movable plates 4 are arranged opposite each other. The movable rods 5 located at the center of the two movable plates 4 are fixedly connected to the movable plates 4. Every two adjacent movable rods 5 on the same movable plate 4 are rotatably connected. One of the movable rods 5 located at the edge of the movable plate 4 is connected to the telescopic rod of an electric telescopic rod 7, which is installed on the corresponding movable plate 4.

[0018] In use, several circuit boards are placed between opposing clamping plates 6. The clamping mechanism 3 drives two movable plates 4 to move closer together, thereby driving the clamping plates 6 on both sides to move closer to the circuit boards and fix them in place. When the spacing between the circuit boards needs to be adjusted, the user controls the electric telescopic rod 7. When the telescopic end of the electric telescopic rod 7 moves towards the main body, it drives the movable rod 5 connected to its telescopic end to move towards the center around the middle movable rod 5. The movable rod 5 drives the clamping plates 6 and the circuit boards to move synchronously, thereby reducing the spacing between the circuit boards. When the telescopic end of the electric telescopic rod 7 moves away from the main body, the movable rods 5 move towards both ends around the middle movable rod 5, driving the clamping plates 6 and the circuit boards to move synchronously to both sides, thereby increasing the spacing between the circuit boards.

[0019] Specifically, in this embodiment, each of the two movable plates 4 has a limiting groove 8, and a limiting block 9 is installed at one end of each of the several movable rods 5 that is connected to the movable plate 4. The limiting block 9 is slidably connected in the corresponding limiting groove 8, so that the several movable rods 5 can be slidably connected to the corresponding movable plate 4 through the compatibility between the limiting block 9 and the limiting groove 8, so that the several movable rods 5 can only move along the direction of the limiting groove 8 when they move, and so that the several movable rods 5 always move horizontally to both sides, thereby achieving the purpose of adjusting the distance between two adjacent movable rods 5.

[0020] Specifically, in this embodiment, the clamping mechanism 3 includes a bidirectional lead screw 31 rotatably connected to the basket 2. The bidirectional lead screw 31 is driven by a servo motor 32, which is mounted on the outer wall of the basket 2. Two movable plates 4 are threadedly connected to both ends of the bidirectional lead screw 31. When the servo motor 32 operates, it drives the bidirectional lead screw 31 to rotate synchronously, thereby driving the two movable plates 4 threadedly connected to the bidirectional lead screw 31 to move closer or further apart, so as to achieve the purpose of clamping and fixing the circuit board by moving the opposing clamping plates 6.

[0021] Specifically, in this embodiment, the basket 2 has two connecting grooves 33, and both ends of the two movable plates 4 are slidably connected in the connecting grooves 33, so that the movable plates 4 can be slidably connected to the basket 2, thereby reducing the load on the movable plates 4. At the same time, the moving direction of the movable plates 4 is restricted by the connecting grooves 33, thereby providing a guarantee for the two movable plates 4 to move towards each other in the horizontal direction.

[0022] Specifically, in this embodiment, each of the movable rods 5 mounted on a movable plate 4 is equipped with a connecting rod 10. The two ends of the connecting rod 10 are respectively connected to two opposing movable rods 5, and the connecting rod 10 is telescopic. The connecting rod 10 allows the opposing movable rods 5 on both sides to be connected as a whole, so that when one movable rod 5 moves, the other movable rod 5 can move equidistantly via the connecting rod 10, thus achieving consistent movement of the two movable rods 5. The telescopic nature of the connecting rod 10 ensures that the space within the basket 2 can accommodate the occupancy requirements of the connecting rod 10 under different conditions during the operation of the clamping mechanism 3.

[0023] Specifically, in this embodiment, a skirt 12 is provided at the upper edge of the basket 2. The skirt 12 contacts the top wall of the ultrasonic cleaner 1, so that the weight of the basket 2 and the components and circuit boards on the basket 2 can be distributed on the ultrasonic cleaner 1, thereby reducing the load on the basket 2 and extending the service life of the device.

[0024] Specifically, in this embodiment, a handle 13 is provided on the skirt 12. The handle 13 facilitates the user to remove the mesh basket 2 from the ultrasonic cleaner 1 to complete the loading and unloading operation of the circuit board.

[0025] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
