Description

TECHNICAL FIELD

[0001] The present application relates to the field of circuit board, especially to a surface treatment equipment for PCB circuit board processing. BACKGROUND

[0002] After the PCB circuit board is processed, it needs to be immersed in chemical water OSP (organic solderability preservative) on the surface of the circuit board for the next electronic component welding process. The chemical water OSP is used for protection of exposed copper to avoid oxidation of copper. In order to improve the immersion efficiency, the existing immersion method is to make multiple circuit board bodies contact with the soaking liquid in the tank at the same time, so that the soaking liquid adheres to the surface of the circuit board body. Then the circuit board body is taken out to drain the excess soaking liquid. Since there are many blind holes on the circuit board body, the soaking liquid will enter the inside of the blind hole during the soaking process. The inside of the blind hole is prone to residual soaking liquid during the draining process. The existing method is to make the residual soaking liquid in the blind hole flow out naturally by swinging. However, this method cannot completely drain the soaking liquid in the blind hole. The residual soaking liquid will cause low drying efficiency in the blind hole and relatively higher thickness of the protective layer in the blind hole, which affects the performance of the PCB board and reduces the draining efficiency.

[0029] The cleaning assembly comprises electric sliding rails 106, sliding blocks 107, a connecting block 108, electric push rods II 109, connecting rods 1010, electric push rods III 1011, rectangular plates 1012, connecting pipes 1013, absorbing cylinders 1014, electric rollers 1015 and absorbing cotton 1016; the connecting plate 103 is provided with a plurality of sliding grooves 1031; the two electric sliding rails 106 are bolted to the connecting plate 103; each electric sliding rail 106 is slidably connected with a sliding block 107; all the sliding blocks 107 are fixedly connected with the connecting block 108, and the connecting block 108 slides in the corresponding sliding groove 1031; each electric push rod II 109 is fixedly connected to the connecting block 108; the telescopic end of each electric push rod II 109 is fixedly connected with a connecting rod 1010, and the connecting rod 1010 is slidably connected with the corresponding connecting block 108; the lower end of each connecting rod 1010 is bolted with an electric push rod III 1011; the telescopic end of each electric push rod III 1011 is fixedly connected with a rectangular plate 1012; each rectangular plate 1012 is rotatably connected with a connecting pipe 1013; each connecting pipe 1013 is connected with an absorbing cylinder 1014, and a sponge is arranged outside the absorbing cylinder 1014, and the absorbing cylinder 1014 is located below the corresponding connecting rod 1010; two electric rollers 1015 are rotatably connected to the lower end of each connecting rod 1010; all the electric rollers 1015 are wound with absorbing cotton 1016, and the absorbing cotton 1016 passes around the outside of the corresponding absorbing cylinder 1014.

[0030] The connecting pipe 1013 is provided with a plurality of inflation holes, and the absorbing cylinder 1014 is made of rubber.

[0031] The connecting pipe 1013 and the absorbing cylinder 1014 are detachably connected.

[0032] In use, first, inject the special chemical soaking liquid OSP for PCB circuit board into the soaking box 2, initially, the fixed frame 101 is located at the rear side of the soaking box 2, the external conveying pump is communicated with the connecting pipe 1013, then the operator controls the telescopic end of the electric push rod I 102 to drive the connecting plate 103 and the clamping plate 104 to rise upwards until the clamping plate 104 is higher than the upper side of the fixed frame 101, then clamps a plurality of circuit board bodies 8 on every two clamping plates 104 in the left-right direction, then controls the telescopic end of the electric push rod I 102 to drive the connecting plate 103 and the clamping plate 104 to slide downwards, the clamping plate 104 slides in the rectangular groove 11 until the lower end of the clamping plate 104 with the circuit board body 8 is flush with the lower side of the fixed frame 101, then controls the electric guide rail I 3 to drive the moving block I 4 to drive the mounting plate 6 and the fixed frame 101 to move forward until the fixed frame 101 is located directly above the soaking box 2, as shown in FIG. Figure 1 At this time, the circuit board body 8 is a certain distance (20 cm) away from the soaking liquid surface.

[0033] Then, the extension end of the electric push rod 102 drives the connecting plate 103 and the clamping plate 104 to slide slowly downward until the clamping plate 104 completely immerses the circuit board body 8 into the soaking tank 2, and then the circuit board body 8 is in contact with the soaking liquid in the soaking tank 2, so that the soaking liquid adheres to the surface of the circuit board body 8. During the soaking process, the soaking liquid enters the blind hole 81 on the circuit board body 8, so that the soaking liquid is easily left in the blind hole 81 during the draining process. Therefore, after the soaking is completed, the extension end of the electric push rod 102 drives the connecting plate 103, the clamping plate 104 and the circuit board body 8 to slowly rise until the circuit board body 8 is separated from the soaking liquid and returns to the initial position. Most of the soaking liquid adhering to the surface of the circuit board body 8 falls downward and returns to the soaking tank 2, and the soaking liquid left in the blind hole 81 cannot flow downward under the action of its own gravity.

[0034] Then, the position of the blind hole 81 on the circuit board body 8 is observed by the camera 105. The camera 105 controls the electric slide rail 106 to move the sliding block 107, the connecting block 108 and the connecting pipe 1013 and the absorbing cylinder 1014 left and right horizontally, and then controls the electric push rod 109 to move the connecting rod 1010 and the parts thereon vertically, so that the connecting pipe 1013 and the absorbing cylinder 1014 are positioned in front of the corresponding blind hole 81. Then, the electric push rod 111 is controlled to move the rectangular plate 1012, the connecting pipe 1013 and the absorbing cylinder 1014 to the side close to the corresponding blind hole 81, so that the absorbing cylinder 1014 and the corresponding absorbing cotton 1016 are separated from each other until the absorbing cylinder 1014 enters the blind hole 81. The sponge on the surface of the absorbing cylinder 1014 absorbs and cleans the excess soaking liquid in the blind hole 81, which avoids the problem that the soaking liquid left in the blind hole cannot be completely drained in the prior art, resulting in a relatively higher thickness of the protective layer in the blind hole and a low draining efficiency. It should be noted that since multiple circuit board bodies 8 are soaked at the same time, the gap between the multiple circuit board bodies 8 is small, and the existing mechanical hand is not convenient for cleaning the excess soaking liquid in the blind hole 81 between the multiple circuit board bodies 8.

[0035] After the cleaning is completed, the electric push rod 111 is controlled to move the rectangular plate 1012, the connecting pipe 1013 and the absorbing cylinder 1014 to the side away from the corresponding blind hole 81, so that the absorbing cylinder 1014 recontacts with the absorbing cotton 1016. At this time, one of the electric rollers 1015 is controlled to rotate to wind the absorbing cotton 1016, and the other electric roller 1015 is controlled to rotate to unwind the absorbing cotton 1016. The connecting pipe 1013 and the absorbing cylinder 1014 rotate relatively under the friction between the connecting pipe 1013 and the absorbing cotton 1016, so that the absorbing cotton 1016 absorbs the soaking liquid in the sponge outside the absorbing cylinder 1014, and the sponge outside the absorbing cylinder 1014 maintains the adsorption ability.

[0036] In view of the fact that the blind holes 81 on the circuit board body 8 have different sizes, if the blind hole 81 with a larger aperture is considered, the absorption cylinder 1014 is difficult to absorb all the excess soaking liquid in the blind hole 81, and if the blind hole 81 with a smaller aperture is considered, the absorption cylinder 1014 is difficult to be put into the blind hole 81. At this time, the connecting pipe 1013 is gasified by controlling the external delivery pump, the gas inflates or deflates the absorption cylinder 1014 made of rubber through the inflation hole, and the absorption cylinder 1014 is adaptively expanded or shrunk under the elastic action of itself, so as to change the diameter of the absorption cylinder 1014 and improve the adaptability of the absorption cylinder 1014.

[0037] In view of the fact that the elasticity of the absorption cylinder 1014 made of rubber is weakened after long-term expansion and shrinkage, the connecting pipe 1013 and the absorption cylinder 1014 are detachably connected, so that the absorption cylinder 1014 can be conveniently and quickly replaced from the connecting pipe 1013.

[0038] In example 2, on the basis of example 1, as shown in Figure 5 The hollow pipes 201 are fixed to the fixed frame 101, and each circuit board body 8 is located between two hollow pipes 201; and the front side, the rear side and the lower side of each hollow pipe 201 are provided with a plurality of delivery holes 2001.

[0039] The liquid collecting hopper 202, the electric guide rail II 203 and the moving block II 204 are further included; the fixed frame 101 is fixedly connected with two electric guide rails II 203; each electric guide rail II 203 is slidably connected with a moving block II 204; and the two moving blocks II 204 are jointly fixedly connected with a liquid collecting hopper 202, and the liquid collecting hopper 202 is located below the corresponding circuit board body 8.

[0040] Each liquid collecting hopper 202 is provided with a plurality of circular holes 2021, and each circular hole 2021 is provided with an electromagnetic valve; and the liquid collecting hopper 202 is arranged in an inverted triangular shape.

[0041] In this embodiment, the external pump machine is communicated with the hollow tube 201. Considering that the circuit board body 8 will generate harmful gases (VOCs gases) and acid mist which are not conducive to the air environment when it is soaked in the soaking tank 2, and which will affect the physical and mental health of the operator, therefore, during the soaking process, the external pump machine is controlled to suck the surface of the soaking liquid through the hollow tube 201, so as to timely suck away the generated harmful gases. Meanwhile, before the circuit board body 8 moves downward into the soaking liquid, if there is dust impurity on the surface of the circuit board body 8 or there is a lot of air in the blind hole 81, the soaking liquid will not be firmly adsorbed on the surface of the circuit board body 8, and the surface of the circuit board body 8 is prone to problems such as air bubble cavity. Therefore, during the process that the circuit board body 8 moves downward into the soaking liquid, the relative movement between the hollow tube 201 and the circuit board body 8 is realized, so that the dust impurity attached to the surface of the circuit board body 8 and the air existing in the blind hole 81 are sucked away by the conveying hole 2001 of the hollow tube 201, and the adhesion effect of the soaking liquid is improved.

[0042] When the circuit board body 8 moves away from the soaking liquid after soaking, part of the soaking liquid will fall into the soaking tank 2 and splash, causing waste. Therefore, during the draining process, the electric guide rail II 203 is controlled to move the moving block II 204 to drive the liquid collector 202 to move, until the liquid collector 202 is located directly below the corresponding circuit board body 8. The soaking liquid falling downward on the circuit board body 8 is collected by the liquid collector 202 on the lower side of the clamping plate 104. Initially, the liquid collector 202 is located away from the circuit board body 8, so as to prevent the liquid collector 202 from hindering the downward movement of the circuit board body 8 for soaking.

[0043] During the draining process, the electromagnetic valve in the circular hole 2021 is first controlled to be closed, so that the circular hole 2021 is closed, and the liquid collector 202 collects the falling paint soaking liquid. After the draining is completed, the electromagnetic valve in the circular hole 2021 is controlled to be opened, so that the circular hole 2021 is opened, and then the soaking liquid in the liquid collector 202 flows back into the soaking tank 2 from the circular hole 2021. Since the liquid collector 202 is arranged in an inverted triangular shape, the soaking liquid continuously flows out of the circular hole 2021 under the action of its own gravity, reducing the residual soaking liquid in the liquid collector 202.

[0044] In embodiment 3, on the basis of embodiment 2, as shown in Figure 7 The connecting rod 1010 is hollow and made of transparent material. Two front and rear symmetrical infrared lamps 301 are fixed in each connecting rod 1010, and there is a gap between the infrared lamps 301 in the same connecting rod 1010.

[0045] The light supplement lamp 302 is further included. One light supplement lamp 302 is fixed to each connecting pipe 1013.

[0046] Each absorption cylinder 1014 is provided with an arc-shaped part 1001 near one side of the corresponding circuit board body 8.

[0047] In this embodiment, the external air pump is connected with the connecting rod 1010. In the process of absorbing the soaking liquid in the absorption cylinder 1014 by the absorbing cotton 1016, acid mist and harmful gas are generated, which pollutes the surrounding working environment. Therefore, when the absorbing cotton 1016 absorbs the liquid in the absorption cylinder 1014, the external air pump is controlled to start, and the absorbing cotton 1016 is sucked through the hollow connecting rod 1010, so that the generated acid mist and VOCs gas are removed.

[0048] During the draining process of the soaked circuit board body 8, the soaking liquid on the surface of the circuit board body 8 needs to be dried and solidified to form a protective layer by firmly adsorbing the soaking liquid on the surface of the circuit board body 8. At this time, the electric push rod II 109, the connecting rod 1010 and the parts thereon are first controlled to move downward until the lower end of the infrared lamp 301 in the connecting rod 1010 is flush with the lower side of the circuit board body 8, and then the infrared lamp 301 is powered on. The heat radiation generated by the infrared lamp 301 passing through the transparent connecting rod 1010 irradiates the circuit board body 8 on both sides at the same time. During the irradiation process, the electric sliding rail 106 is controlled to move the sliding block 107 and the connecting block 108 and the connected parts horizontally, so that the infrared lamp 301 dries and solidifies the soaking liquid on both sides of each circuit board body 8.

[0049] During the irradiation and solidification process, the external air pump is controlled to start, and air is blown downward along the gap between the two infrared lamps 301 through the hollow connecting rod 1010, so as to cool the back of the two infrared lamps 301, preventing the infrared lamps 301 from being affected by poor heat dissipation in the relatively small space of the connecting rod 1010.

[0050] Considering that the light of the infrared lamp 301 cannot accurately irradiate the inside of the blind hole 81, the soaking liquid in the blind hole 81 cannot be completely dried and solidified, which affects the overall draining efficiency of the circuit board body 8. Therefore, the light supplementing lamp 302 is powered on, and then the position of the blind hole 81 is observed by the camera 105, and the electric sliding rail 106, the electric push rod II 109 and the electric push rod III 1011 are controlled by the camera 105 to move the corresponding connecting pipe 1013 and the light supplementing lamp 302 to the area of the corresponding blind hole 81, so that the light supplementing lamp 302 irradiates the inside of the blind hole 81, and then the inside of the blind hole 81 is quickly dried, and the draining efficiency is improved.

[0051] Further considering that the resistance between the outer wall of the absorbing cylinder 1014 and the inner wall of the blind hole 81 is large when the connecting pipe 1013 and the absorbing cylinder 1014 enter the inside of the blind hole 81 in Embodiment 1, so that the absorbing cylinder 1014 is difficult to enter the inside of the blind hole 81, therefore, the arc-shaped part 1001 is arranged on the side of the absorbing cylinder 1014 close to the circuit board body 8, so as to reduce the resistance when the absorbing cylinder 1014 enters the inner wall of the blind hole 81, and facilitate the absorbing cylinder 1014 to enter the inside of the blind hole 81.

[0052] The above merely describes the preferred embodiments of the present application, and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
