Description

Technical Field

[0001] The utility model belongs to the technical field of circuit board processing, and in particular relates to a desmearing device for circuit board processing. Background Art

[0002] Circuit boards are providers of electrical connections for electronic components. According to the number of layers of the circuit boards, they can be divided into single-sided boards, double-sided boards, four-layer boards, six-layer boards and other multi-layer boards. In the process of connecting panels with two layers or more, it is generally necessary to use glue to stick the panels together. In the process of gluing, it is inevitable that glue will overflow on the side walls, which needs to be de-glueized.

[0003] Existing desmearing devices for circuit board processing have certain problems in practical application: for example, the circuit board is placed on a screen frame and then immersed in an immersion box for desmearing. After the desmearing is completed, in order to save time, the screen frame is generally taken out directly, and then replaced with the screen frame containing the circuit board to be desmeared. The circuit board that has been desmeared cannot be effectively drained, resulting in waste of desmearing liquid and dripping of the desmearing liquid on the factory floor. Utility Model Content

[0004] In order to solve the problems raised in the above background technology, the utility model provides a desmearing device for circuit board processing, which has the characteristics of effectively draining water from the desmeared circuit board without affecting the desmearing efficiency.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a desmearing device for circuit board processing, comprising a desmearing box, a mounting bracket is connected to the top of the desmearing box, a rotating frame is rotatably arranged on the mounting bracket, a motor is installed on one side of the mounting bracket, the output end of the motor is connected to the rotating shaft of the rotating frame, and a plurality of mesh frames are hung on the rotating frame.

[0006] Furthermore, the rotating frame includes two symmetrically arranged supporting side plates, the supporting side plates are provided with two or three supporting feet, and a hanging rod is connected between the supporting feet opposite to the two supporting side plates. The two or three supporting feet are arranged in rotational symmetry.

[0007] In order to accurately control the rotation angle of the rotating frame, further, the motor is a servo motor.

[0008] In order to facilitate the disassembly and assembly of the net frame and the hanging rod, two symmetrically arranged hooks are further connected to the top of the net frame.

[0009] In order to facilitate taking and placing the screen frame, two symmetrically arranged handles are further connected to the top of the screen frame.

[0010] In order to separate and limit the circuit board, further, a plurality of separation blocks arranged at equal intervals are provided on the inner wall of the screen frame.

[0011] In order to pad the bottom of the circuit board and provide a gap between the bottom of the circuit board and the screen frame, thereby ensuring that the circuit board can fully contact with the deslagging liquid, further, a pad is provided at the inner bottom of the screen frame between two adjacent partition blocks.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model installs a rotating frame above the de-glue slag box, and two screen frames are hung on the rotating frame. The rotating frame is driven by a motor to rotate. When one screen frame is located inside the de-glue slag box for de-glue slag operation, the other screen frame is located above the de-glue slag box, so that the de-glue liquid can be effectively drained to avoid the de-glue liquid from being wasted or dripping on the factory floor;

[0014] 2. The upper part of the net frame of the utility model is connected with two symmetrically arranged hooks, which facilitates the disassembly and assembly of the net frame and the hanging rod;

[0015] 3. The utility model is provided with three supporting feet on the supporting side plate, and the three supporting feet are arranged in rotational symmetry. By arranging the three supporting feet, the drainage time can be effectively increased, thereby ensuring the drainage effect;

[0016] 4. The inner bottom of the screen frame of the utility model is provided with a pad between two adjacent partition blocks to raise the bottom of the circuit board so that there is a gap between the bottom of the circuit board and the screen frame, thereby ensuring that the circuit board can fully contact with the slag removal liquid.
