[0001] The utility model relates to the technical field of PCB circuit boards, in particular to a surface treatment device for processing PCB circuit boards. Background Art

[0002] SMT patch refers to the abbreviation of a series of process flows based on PCB circuit boards. When patching PCB circuit boards, a plasma surface treatment machine is usually required to clean the surface of the PCB circuit board.

[0003] However, in the existing plasma surface treatment machines, when in use, most of them place the PCB circuit board on a slide, and drive the slide and the plasma treatment head to move vertically and horizontally through two screws to treat the surface of the circuit board. Therefore, there are certain requirements for the movement of the two screws, which increases the processing difficulty and cost. Therefore, we propose a surface treatment device for PCB circuit board processing to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a surface treatment device for PCB circuit board processing to solve the problem that the current plasma surface treatment machine proposed in the above background technology, during use, mostly places the PCB circuit board on a slide, and drives the slide and the plasma treatment head to move vertically and horizontally by two screw rods to process the surface of the circuit board, so it is necessary to have certain requirements on the movement of the two screw rods, which increases the difficulty of processing and increases the cost.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a surface treatment device for PCB circuit board processing, comprising:

[0006] A plasma processing machine body, wherein a boss is arranged on the top right side of the plasma processing machine body, and a slide is arranged above the boss;

[0007] A guide rail frame, the guide rail frame is arranged above the middle part of the plasma processing machine body, and a guide rod is installed on the top of the guide rail frame, a shaft rod is installed on the left side of the guide rail frame, and a second turntable is installed on the top of the shaft rod, a first turntable is arranged at the bottom of the shaft rod, and a motor is installed at the bottom end of the shaft rod, and the motor is fixedly connected to the plasma processing machine body;

[0008] The slider is arranged on the outside of the guide rod, and the top of the slider is connected to the second turntable through a pull rod. The bottom of the slider is connected to a mounting plate, and the bottom end of the mounting plate is installed with a plasma processing head.

[0009] Preferably, friction strips are symmetrically arranged on the left and right sides of the boss, and the friction strips are fixedly connected to the boss via fastening screws.

[0010] Preferably, the slide is arranged in a "concave" structure, and the slide and the convex platform constitute a sliding structure, and a serrated structure is arranged on the left side of the slide.

[0011] Preferably, a serrated structure is provided on both the left and right sides of the first rotating disk, and the serrated structure on the first rotating disk is meshed with the serrated structure on the sliding platform.

[0012] Preferably, the second turntable is eccentrically rotationally connected to the pull rod, and the pull rod is rotationally connected to the slider, and the second turntable forms a transmission mechanism through the pull rod and the slider.

[0013] Preferably, the slider is snap-connected with the guide rail frame, and the slider forms a sliding structure with the guide rail frame via a guide rod.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows: the surface treatment device for PCB circuit board processing can drive the first turntable and the second turntable to rotate synchronously through the rotation of the shaft rod. When the first turntable rotates, the sawtooth structure on the first turntable can drive the slide table to slide, thereby facilitating the movement of the PCB circuit board on the slide table. The sawtooth structure on the first turntable is separated from the sawtooth structure on the slide table, which is convenient for the PCB circuit board to stay. At the same time, the second turntable can pull the slide table to slide back and forth through the pull rod, thereby facilitating comprehensive treatment of the PCB circuit board, and there is no need to use two screw rods to drive the slide table and the plasma treatment head to move, thereby improving operation stability and saving costs.

[0015] Friction strips are arranged at the slide and the boss to increase the friction between the slide and the boss, so that when the sawtooth structure on the slide is separated from the sawtooth structure on the first rotating disk, the slide will not slide, thereby improving the accuracy.

[0025] A guide rail frame 6, the guide rail frame 6 is arranged above the middle part of the plasma processing machine body 1, and a guide rod 7 is installed on the top of the guide rail frame 6, a shaft rod 8 is installed on the left side of the guide rail frame 6, and a second turntable 10 is installed on the top of the shaft rod 8, a first turntable 9 is arranged at the bottom of the shaft rod 8, and a motor 11 is installed at the bottom end of the shaft rod 8, and the motor 11 is fixedly connected to the plasma processing machine body 1;

[0026] The slider 12 is arranged on the outside of the guide rod 7, and the top of the slider 12 is connected to the second turntable 10 through a pull rod 15. A mounting plate 13 is connected below the slider 12, and a plasma processing head 14 is installed at the bottom end of the mounting plate 13.

[0027] like Figure 1 , Figure 2 and Figure 3 Friction strips 3 are symmetrically arranged on the left and right sides of the middle boss 2, and the friction strips 3 are fixedly connected to the boss 2 by fastening screws 4, which is convenient for increasing the friction between the slide 5 and the boss 2 so that the slide 5 can stay stably. The slide 5 is arranged in a "concave" structure, and the slide 5 and the boss 2 constitute a sliding structure, and a serrated structure is arranged on the left side of the slide 5 to improve the sliding stability of the slide 5 and the boss 2.

[0028] like Figure 1 , Figure 2 , Figure 4 and Figure 5 The left and right sides of the first turntable 9 are provided with serrated structures, and the serrated structures on the first turntable 9 are meshed with the serrated structures on the slide 5, so that the first turntable 9 drives the slide 5 to slide. The second turntable 10 is eccentrically connected to the pull rod 15, and the pull rod 15 is rotatably connected to the slider 12, and the second turntable 10 forms a transmission mechanism with the slider 12 through the pull rod 15, so that the second turntable 10 drives the slider 12 to slide through the pull rod 15. The slider 12 is engaged with the guide rail frame 6, and the slider 12 forms a sliding structure with the guide rail frame 6 through the guide rod 7, which increases the stability of the slider 12 and facilitates the horizontal movement of the plasma processing head 14.

[0029] Working principle: When using the surface treatment device for PCB circuit board processing, Figure 5 As shown, the PCB circuit board is placed on the slide 5, and the motor 11 is started to drive the shaft 8 to rotate. When the shaft 8 rotates, the pull rod 15 is pulled by the second turntable 10 to drive the slider 12 to slide on the guide rod 7, thereby driving the plasma processing head 14 to move and process the surface of the PCB circuit board. At the same time, when the shaft 8 rotates, the shaft 8 drives the sawtooth structure on the first turntable 9 to engage with the sawtooth structure on the slide 5, so that the first turntable 9 drives the slide 5 to slide on the boss 2, and the unprocessed surface on the slide 5 is moved. The PCB circuit board is moved to the bottom of the plasma processing head 14. After the sawtooth structure on the first turntable 9 is separated from the sawtooth structure on the slide 5, the slider 12 is driven to move in the opposite direction under the continuous rotation of the second turntable 10 to clean the PCB circuit board. The rotation of the first turntable 9 and the second turntable 10 driven by the shaft 8 can respectively drive the slide 5 and the slider 12 to move vertically and horizontally, thereby facilitating comprehensive cleaning of the PCB circuit board. After the PCB circuit board is cleaned, the slide 5 can be manually pulled to reset.

[0030] like Figure 4 As shown, the friction strips 3 at the slide 5 and the boss 2 increase the friction between the slide 5 and the boss 2, so that the slide 5 can stop stably, avoiding different movement distances of the slide 5 each time. This is the entire working process of the surface treatment device for PCB circuit board processing.
