Description

Technical Field

[0001] The present invention relates to the technical field of circuit board processing equipment, and in particular to a circuit board desmearing device and method. Background Art

[0002] In the circuit board manufacturing process, desmearing is a key process link. Its main purpose is to remove the resin smear remaining on the circuit board surface and in the holes during drilling or other processing. If these smears are not effectively removed, it will directly affect the quality of subsequent metallized holes and even cause defects such as circuit short circuits or open circuits, affecting the performance and reliability of the circuit board.

[0003] Currently, common desmear removal equipment typically immerses the circuit board in a sol to soften the smear, then physically scrubs the surface with a rotating brush to remove any remaining smear. However, over time, a large amount of smear adheres to the brush, reducing its scrubbing efficiency and impacting the removal process. Furthermore, the sol gradually loses its effectiveness over time due to smear accumulation and changes in its chemical composition, necessitating electrolytic regeneration or replacement.

[0032] like Figures 8-10 As shown, the immersion assembly includes a fixed plate 25, a third screw motor 26, a liquid storage tank 27, an electrolysis mechanism 28, a collection frame 29, a connecting spring 30, a drain pipe 31 and a control valve 32. The lower part of the support frame 1 is connected to the fixed plate 25, and the middle part of the fixed plate 25 is installed with the third screw motor 26. The top right side of the fixed plate 25 is slidingly connected to two liquid storage tanks 27, and the lower parts of the two liquid storage tanks 27 are both threadedly connected to the screw of the third screw motor 26. The inside of the two liquid storage tanks 27 is installed with an electrolysis mechanism 28. The top left side of the fixed plate 25 is slidingly connected to the collecting frame 29, and a connecting spring 30 is connected between the lower part of the collecting frame 29 and the fixed plate 25. The bottom right side of the collecting frame 29 is connected to the drain pipe 31 and keeps it connected, and a control valve 32 is installed on the drain pipe 31.

[0033] When the device is needed, first install the device at the designated position, so that the front conveyor 24 is docked with the discharge conveyor of the previous processing step of the circuit board, so that the discharge conveyor can transport the circuit board backward to the front conveyor 24, and the rear conveyor 24 will be docked with the feed conveyor of the next processing step of the circuit board; then put an appropriate amount of sol liquid into the two liquid storage tanks 27, and then drive the right lifting frame 17 to move downward through the second screw motor 19 on the right, and the right lifting frame 17 can drive the right discharge frame 18 to move downward, so that the right discharge frame 18 is aligned with the conveyor 24, and then pass through the front conveyor 2 4 The circuit board is conveyed backward to the discharge frame 18 on the right. At this time, the bottom of the circuit board will contact the roller 21, and then the second screw motor 19 on the right drives the discharge frame 18 on the right to continue to move downward. The discharge frame 18 on the right can drive the circuit board to move downward into the liquid storage tank 27 on the left, so that the circuit board can fully contact the sol liquid. Then, the second screw motor 19 on the right drives the discharge frame 18 on the right to move upward and reset, so that the discharge frame 18 on the right is higher than the conveyor 24. The discharge frame 18 on the right can drive the circuit board to move upward away from the liquid storage tank 27 on the left, and make the top of the circuit board contact the brush cylinder 6 on the lower side, and then the second screw motor 19 drives the circuit board to move upward and away from the liquid storage tank 27 on the left, and make the top of the circuit board contact the brush cylinder 6 on the lower side. The machine 14 drives the second worm 15 to rotate, and the second worm 15 drives the second worm gear 16 to rotate 180 degrees. The second worm gear 16 drives the rotating frame 2 to rotate 180 degrees. The rotating frame 2 can drive the two discharge frames 18 to rotate 180 degrees, so that the two discharge frames 18 exchange positions; then the driving motor 5 drives the brush cylinder 6 to rotate, and the brush cylinder 6 can brush the surface of the circuit board to remove the residual glue residue on the surface of the circuit board. At this time, the sol liquid remaining on the surface of the circuit board will fall down by gravity into the collection frame 29 for collection. In the process of cleaning the circuit board, the above operation is repeated to transport the next circuit board to the other discharge frame 18 and pass The circuit board is driven downward by another unloading frame 18 to be immersed in the sol liquid; then the rotating frame 2 is controlled to rotate 180 degrees again, so that the two unloading frames 18 can be swapped again, and the glue residue remaining on the surface of the next circuit board can be removed at this time; when the unloading frame 18 with the processed circuit board is lowered to be aligned with the conveyor 24, the rotating rod 20 and the roller 21 can be driven to rotate by the third motor 22 and the pulley assembly 23. The roller 21 can convey the circuit board backward to the conveyor 24 on the rear side through the friction between it and the circuit board. The circuit board can be conveyed backward to the next processing step of the circuit board through the conveyor 24 on the rear side;Then the conveyor 24 on the front side can convey a new circuit board into the discharge frame 18, and then the first motor 7 can drive the first worm 8 to rotate, the first worm 8 can drive the first worm gear 9 to rotate 180 degrees, the first worm gear 9 can drive the rotating frame 4 to rotate 180 degrees, and the rotating frame 4 drives the upper and lower brush cylinders 6 to rotate 180 degrees, so that the upper and lower brush cylinders 6 exchange positions, so that the new circuit board can be cleaned of glue residue by the new brush cylinder 6; and the used brush cylinder 6 will contact with the cleaning frame 10, and as the brush cylinder 6 rotates The cleaning rack 10 can scrape off the glue residue adhering to the brush barrel 6, so that the glue residue falls on the cleaning rack 10, and then the first screw motor 11 regularly drives the movable plate 13 to move back and forth left and right, and the movable plate 13 can push the glue residue on the cleaning rack 10 to fall into the collection box 12, and so on. The brush barrel 6 can be cleaned automatically to ensure the cleaning effect of the brush barrel 6; when the sol liquid in the left liquid storage tank 27 is about to expire, the two liquid storage tanks 27 can be driven to move a specified distance to the left by the third screw motor 26. When the left liquid storage tank 27 When it contacts the collecting frame 29, it can push the collecting frame 29 to move to the left, and the connecting spring 30 is compressed. At this time, the two liquid storage tanks 27 are respectively located directly below the two discharge frames 18, so that the subsequent circuit boards can enter the right liquid storage tank 27 for sol soaking when they descend, and the sol remaining on the surface of the circuit board where the glue residue is being removed will fall down to the left liquid storage tank 27 by gravity for collection. At this time, the electrolysis mechanism 28 in the left liquid storage tank 27 can be energized, and the sol in the liquid storage tank 27 can be eluted by the action of the electrolysis mechanism 28. Similarly, when the sol in the right liquid storage tank 27 is about to expire, the third screw motor 26 can be used to drive both liquid storage tanks 27 to move rightward and reset. At this time, the left liquid storage tank 27 will be separated from the collection frame 29, and the connecting spring 30 will return to its original state, driving the collection frame 29 to move rightward and reset, so that the collection frame 29 can collect the sol again. When the sol in the collection frame 29 needs to be removed, the control valve 32 can be opened to allow the sol in the collection frame 29 to be discharged downward through the drain pipe 31, facilitating manual one-time collection.

[0034] like Figure 11As shown, it also includes a fixing assembly, which includes a slide bar 33, a pressure plate 34, a connecting plate 35, a return spring 36, a guide rod 37, a contact frame 38 and an electric push rod 39. The lower part of the two discharging frames 18 facing each other is slidably connected with two slide bars 33, and a pressure plate 34 is connected between one end of the two slide bars 33. The pressure plate 34 is located on the inner side of the discharging frame 18, and a connecting plate 35 is connected between the other ends of the two slide bars 33. The upper end of the connecting plate 35 is set to an arc surface. A return spring 36 is wound around the outside of each sliding rod 33, and the two ends of the return spring 36 are respectively connected to the discharge frame 18 and the connecting plate 35. A guide rod 37 is slidably connected to the lower right side of the rotating frame 2, and the bottom of the guide rod 37 is connected to the contact frame 38. The left and right sides of the contact frame 38 are provided with inclined surfaces, and the inclined surfaces on the contact frame 38 are in contact with the arc surface on the connecting plate 35. An electric push rod 39 is installed on the left side of the lower part of the rotating frame 2, and the telescopic rod of the electric push rod 39 is connected to the contact frame 38.

[0035] When the brush barrel 6 is removing glue residue from the surface of the circuit board, the contact frame 38 can be driven downward by the electric push rod 39. Since the right discharge frame 18 drives the circuit board to move downward into the liquid storage tank 27 for sol liquid immersion, the right discharge frame 18 will drive the right connecting plate 35 to move downward for a distance, so the contact frame 38 will not contact the right connecting plate 35, and the contact frame 38 will squeeze the left connecting plate 35 to move to the left. The left return spring 36 is compressed, and the left connecting plate 35 will drive the left slide bar 33 and the left pressure plate 34 to move to the left. The left pressure plate 34 is made to contact the side of the circuit board. The pressure plate 34 cooperates with the discharge frame 18 to clamp and fix the circuit board to prevent the circuit board from moving due to the friction between it and the brush cylinder 6, thereby ensuring the cleaning effect of the brush cylinder 6. When the cleaning work is completed, the contact frame 38 can be driven upward by the electric push rod 39 to reset. The contact frame 38 will be disengaged from the left connecting plate 35. At this time, the left reset spring 36 will return to its original state, driving the left connecting plate 35, the left slide bar 33 and the left pressure plate 34 to move to the right and reset, so that the left pressure plate 34 releases the circuit board.

[0036] like Figure 11 As shown, it also includes an air pump 40, a connecting pipe 41 and an air outlet frame 42. The air pump 40 is installed on the front left and rear right sides of the lower part of the rotating frame 2. The air outlets of the two air pumps 40 are connected to the connecting pipes 41 and remain connected. The lower ends of the two connecting pipes 41 are connected to the air outlet frames 42 and remain connected. When the brush barrel 6 is removing glue residue from the surface of the circuit board, air can be extracted through the air pump 40, and a large amount of air can be transported to the air outlet frame 42 through the connecting pipe 41, so that the air outlet frame 42 can blow air toward the circuit board, so that the sol liquid remaining on the surface of the circuit board can be quickly drained.

[0037] like Figure 12As shown, a filter frame 43 is also included. The filter frame 43 is placed on the upper inner part of the two liquid storage tanks 27, and the filter frame 43 is located above the electrolysis mechanism 28; the filter frame 43 can filter the sol liquid in the liquid storage tank 27 to prevent impurities in the sol liquid from falling down into the electrolysis mechanism 28, ensuring that the electrolysis mechanism 28 can operate normally. When there are too many impurities remaining on the filter frame 43, the filter frame 43 can be directly taken out of the liquid storage tank 27 for cleaning, and then the filter frame 43 can be put back in place.
