Description
Technical Field
[0001] The utility model relates to the technical field of circuit board processing, in particular to a circuit board copper deposition detection device. Background Art
[0002] Circuit boards make circuits miniaturized and intuitive, and play an important role in the mass production of fixed circuits and the optimization of electrical appliance layout. When actually processing circuit boards, it is necessary to copper-plate the inner walls of the through holes on the surface of the circuit boards. This process is called copper plating. After copper plating, the circuit boards need to use a backlight detection device to complete the copper plating coverage detection work. In actual use, it has the advantages of simple operation, stable structure and good use effect.
[0003] The prior art discloses a PCB hole wall metallization backlight detection fixture with publication number: CN210071693U, which includes a magnifying glass, a fixing seat, a mounting slot, a supporting plate, a light source, a pull-out slice clamp, a box body, a slice placement slot and a through hole. The ground backlight slice is placed in the slice placement slot on the upper part of the pull-out slice clamp, and the slice is pushed onto a transparent glass plate through the pull-out slice clamp. The LED light is turned on, and then the slice is observed through the through hole through a 50x high-foot magnifying glass. The backlight level is determined by the number of translucent bright spots in the slice. If the copper deposition coverage effect is not good, translucent bright spots will appear. The more translucent bright spots, the worse the backlight effect. The production cost is low, and the equipment maintenance cost is reduced.
[0004] When the above utility model is used, it is necessary to place the slice inside the slice placement groove, and then move the pull-out slice clamp into the installation groove. When the detection is completed, the pull-out slice clamp needs to be moved out of the installation groove. Due to the existence of the through hole, the magnifying glass and the support plate are placed in the air. When the dust in the air contacts the magnifying glass and the support plate, the impurities will affect the accuracy of subsequent backlight detection, thereby reducing the practicality of the use of this utility model.
[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0036] Working principle:
[0037] When the circuit board copper deposition detection device is actually used, the operator first makes the copper wall into slices, and then puts them into the pull-out slice clamp 9. The operator then manually inserts the pull-out slice clamp 9 through the T-shaped through slot 8. When one end of the pull-out slice clamp 9 is inserted into the slot 11, the cover plate 10 is located inside the T-shaped through slot 8. At this time, the T-shaped through slot 8 is sealed. At this time, using the fixed tube 16 and the bearing 17, since the thread of the wire lever 18 and the screw sleeve 19 cooperate with each other, the operator manually rotates the wire lever 18 counterclockwise to push the screw sleeve 19 to move left. The lead screw sleeve 19 can drive the two groups of baffles 7 to move leftward through the concave plate 15.

When the two groups of sealing plates 14 on the right side move into the two groups of first built-in grooves 1 2, the two sets of sealing plates 14 on the left side are moved into the two sets of second built-in grooves 13. At this time, due to the existence of the two sets of baffles 7, no impurities will contact the magnifying glass 2 and the transparent glass plate 4. The baffles 7 can prevent the magnifying glass 2 and the transparent glass plate 4 from contacting with impurities in the air and being scratched by them, thereby improving the practicality of the circuit board copper deposition detection device. At the same time, when it is necessary to disassemble the transparent glass plate 4, the control panel is used to make the round electric heater 24 work, and the high temperature generated by the round electric heater 24 can be The column 22 is transferred to the mounting hole plate 3, and the mounting hole plate 3 then transfers the high temperature to the glue 5 through multiple groups of metal rods 20. When the glue 5 melts, the transparent glass plate 4 can be removed. This operation can conveniently disassemble and assemble the transparent glass plate 4. The circular cover 23 can prevent foreign objects from contacting the circular electric heater 24. Multiple groups of asbestos tubes 21 serve the purpose of heat insulation.
