Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-5, the present utility model provides a technical solution:

The utility model provides an electronic circuit board frictioning clean-up equipment, has offered cavity 2 in casing 1, and annular 3 has been seted up to casing 1's outer wall, and annular 3 department laminating has brush 6, and annular 3 department has been seted up the trompil 4 of intercommunication cavity 2, and casing 1's bottom fixedly connected with flat spade 5, cavity 2 internal rotation is connected with rotary rod 7, fixedly connected with arc piece 8 on rotary rod 7's the outer wall, be equipped with the shutoff piece to cavity 2 shutoff on the casing 1. The cavity 2 is used for receiving banana oil, the banana oil wets the hairbrush 6 through the opening 4, and a worker can use the hairbrush 6 to paint the banana oil on a waterproof glue position on the circuit board. The part of the inner ring sleeve of the brush 6, which is sleeved on the annular groove 3, is made of elastic materials, so that when the inner ring sleeve of the brush 6 is sleeved on the annular groove 3, the brush 6 is tightly connected with the annular groove 3, and when the brush 6 brushes banana water on a circuit board, the brush 6 cannot rotate.

Specifically, as shown in fig. 3, the plugging piece comprises a sleeve block 11 which is connected with the inner wall of the cavity 2 through threads, a vertical hole 12 which is connected with the rotary rod 7 in a sliding manner is formed in the sleeve block 11, a rubber plug 13 is fixedly connected to the sleeve block 11, and a limiting piece which limits the rotary rod 7 is further arranged on the shell 1. A sealing ring is arranged on the contact part of the vertical hole 12 and the outer wall of the rotary rod 7. Therefore, after the sleeve block 11 is sleeved on the rotary rod 7, the opening of the cavity 2 can be plugged under the action of the rubber plug 13, so that banana oil in the cavity 2 is prevented from leaking.

Specifically, as shown in fig. 2, the limiting member includes a polygonal slot 9 formed at the end of the rotary rod 7, a sliding hole 14 is formed in the housing 1, a bent rod 15 is slidably connected to the sliding hole 14, one end of the bent rod 15 is fixedly connected to a polygonal block 16, and the other end is fixedly connected to an end block 17. The bent rod 15 is sleeved with a spring 18, one end of the spring 18 is fixedly connected with the shell 1, and the other end of the spring is fixedly connected with the upper surface of the end block 17. The elastic force of the spring 18 pushes the polygonal block 16 to move downwards until the polygonal block 16 stretches into the polygonal groove 9 formed in the rotary rod 7, so that the rotary rod 7 is limited, and the rotary rod 7 cannot rotate under the force.

Specifically, as shown in fig. 4, a stop block 10 is fixedly connected to the inner wall of the cavity 2, and the arc-shaped block 8 rotates positively and negatively to contact with different surfaces of the stop block 10 to control whether the arc-shaped block 8 shields the opening 4 or not. Therefore, the rotation rod 7 has a limited forward and reverse rotation angle, and the forward and reverse rotation effects are different.

In summary, when the tool is used, banana oil is poured into the cavity 2, and then the sleeve block 11 can be rotated, so that the sleeve block 11 is connected with the cavity 2 through threads until the rubber plug 13 seals the opening of the cavity 2. After the circuit board is placed, the bent rod 15 is pushed to move upwards until the polygonal block 16 is separated from the polygonal groove 9, the rotary rod 7 can be rotated at the moment until the side wall of the arc-shaped block 8 is abutted with the stop block 10, the opening 4 is exposed at the moment, and banana water wets the hairbrush 6 through the opening 4. The pushing force to the bent rod 15 is released, and the bent rod 15 moves downwards under the action of the elastic force of the spring 18 until the polygonal block 16 stretches into the polygonal groove 9, so that the position of the rotating rod 7 is limited again. After waiting for a moment, the flat spade 5 on the shell 1 can be used for spading the waterproof glue on the circuit board.

The previous description of the embodiments is provided to enable any person skilled in the art to make or use the present utility model.
