[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0024] like Figures 1-5 As shown, this utility model provides a quick assembly and disassembly conveying mechanism based on wet circuit board process, including a transmission component, multiple power wheels 9, and a conveying base 10. The top two sides of the conveying base 10 are inclined to avoid the residue washed off (such as photoresist residue and saponified substances from chemical reactions) from stagnating on the surface of the conveying base 10 and becoming difficult to clean due to long-term adhesion.

[0025] The conveying base 10 is provided with a plurality of evenly symmetrical insertion holes 101. A power wheel bracket 12 is provided in the insertion hole 101. The power wheel bracket 12 is provided with an axial shaft hole 120. A U-shaped groove 121 is provided radially on the top side of the power wheel bracket 12. The shaft hole 120 is rotatably connected to the bottom end of the conveying shaft 13. The top of the conveying shaft 13 is movably connected to the conveying shaft fixing seat 16. A groove 92 is provided circumferentially on the edge of the power wheel 9.

[0026] Multiple conveying rollers 14 are provided on the conveying shaft 13, and threaded holes are provided through the sleeves of the conveying rollers 14, with locking screws 15 connected inside the threaded holes.

[0027] The two ends of the shaft of the power wheel 9 are movably connected to two symmetrically arranged U-shaped grooves 121.

[0028] Both ends of the conveyor shaft fixing seat 16 are provided with slots, and the top of the conveyor shaft 13 is rotatably connected with a conveyor bearing cap 17, which is movably disposed in the slot.

[0029] A conveying bevel gear 8 is fixedly installed at the bottom of the conveying shaft 13, and a driven bevel gear 91 is installed on one side of the power wheel 9.

[0030] The transmission assembly includes: a transmission base 1 respectively disposed on both sides of the conveying base 10; a transmission bearing seat 2 fixedly disposed on the outer side of the transmission base 1; the transmission bearing seat 2 being rotatably connected to a transmission shaft 3; a plurality of driving bevel gears 4 fixedly disposed on the transmission shaft 3; and a plurality of driven bearing seats 11 disposed on the outer side of the conveying base 10 and on the transmission base 1; the driven bearing seats 11 being rotatably connected to the driven shaft 6. This method facilitates maintenance.

[0031] Driven bevel gear 5 and driven bevel gear 7 are fixedly installed at both ends of driven shaft 6, and driven bevel gear 4 meshes with driven bevel gear 5. Driven bevel gear 7 meshes with conveying bevel gear 8, and conveying bevel gear 8 meshes with driven bevel gear 3 on one side of power wheel 9.

[0032] The detailed working process of this utility model is as follows: 1. The two ends of the shaft of the drive wheel 9 are movably connected to two symmetrically arranged U-shaped grooves 121. The conveying rollers 14 are symmetrically and vertically arranged on the conveying base 10. The grooves on the drive wheel 9 cooperate with the conveying rollers 14 to form a conveying channel for the printed circuit board. In use, the drive shaft 3 drives multiple driven shafts 6 to rotate through multiple driving bevel gears 4 and multiple driven bevel gears 5. The multiple driven shafts 6 drive multiple conveying shafts 13 and multiple drive wheels 9 to rotate through multiple driven bevel gears 7 and multiple conveying bevel gears 8. The multiple conveying shafts 13 drive several conveying rollers 14 to rotate, thereby conveying the printed circuit board 18.

[0033] 2. When replacing the power wheel 9, simply lift the conveyor shaft 13 upwards to remove the power wheel 9 for replacement; after replacement, lower the conveyor shaft 13 so that the conveyor bevel gear 8 meshes with the driven bevel gear on the new power wheel 9, and the device starts working again.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
