DETAILED DESCRIPTION
[0017] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0018] Depend on Figure 1-4 The utility model includes an electroplating pool 1 and a circuit board 10. First hydraulic rods 2 are fixedly installed on both sides of the electroplating pool 1. Top plates 3 are fixedly installed at the telescopic ends of the two first hydraulic rods 2. Vertical connecting plates 5 are fixedly installed at both ends of the bottom of the top plate 3. A U-shaped storage rack 4 is fixedly installed between the bottom ends of the two connecting plates 5. Grooves are provided at the tops of the vertical parts on both sides of the storage rack 4. Second hydraulic rods 7 are fixedly installed in the two grooves. Lifting plates 8 are fixedly installed at the telescopic ends of the two second hydraulic rods 7. A recessed area is provided at the bottom of the lifting plate 8. A pressing plate 9 is movably installed, and a plurality of slots 12 are evenly opened at the bottom of the pressing plate 9. A bottom plate 11 having the same number of slots 12 is evenly and fixedly installed on the top of the horizontal portion of the storage rack 4. A circuit board 10 is located between the bottom plate 11 and the pressing plate 9, and the bottom end of the circuit board 10 is plugged into the top of the bottom plate 11. The top end of the circuit board 10 is engaged in the slot 12 at the bottom of the pressing plate 9. Two left-right symmetrical vibration motors 6 are fixedly installed at the bottom of the horizontal portion of the storage rack 4. The vibration generated by the vibration motor 6 can remove surface bubbles from the circuit board 10 immersed in the electroplating bath 1.
[0019] like Figure 2 and Figure 4 As shown, a slot 16 is provided at the top of the bottom plate 11, and limiting slots 17 are provided at both ends of the slot 16. The bottom end of the circuit board 10 is located in the slot 16 at the top of the bottom plate 11, and the two ends of the bottom of the circuit board 10 are respectively engaged in the limiting slots 17 at both ends of the slot 16.

Through the arrangement of the spring 15, a reserved space for the pressing plate 9 to move upward can be provided, thereby preventing the pressing plate 9 from excessively squeezing the circuit board 10, and preventing the vibration generated by the vibration motor 6 from damaging the circuit board 10. If the circuit board 10 is completely fixed and clamped, the vibration generated by the vibration motor 6 can easily cause damage to the squeezed position of the circuit board 10.
[0021] like Figure 2 and Figure 3 As shown, the diameter of the top end of the connecting bolt 14 is greater than the diameter of the through hole 13, so that the connecting bolt 14 can be inserted into the through hole 13 and cannot be separated from the through hole 13.
[0022] like Figure 1 As shown, when the bottom of the top plate 3 contacts the top of the electroplating tank 1 , the racks 4 are located in the middle of the electroplating tank 1 , so that the multiple circuit boards 10 fixedly clamped between the racks 4 can be immersed in the electroplating tank 1 at the same time.
[0023] like Figure 1 and Figure 2 As shown, the card slot 12 at the bottom of the pressing plate 9 is engaged with the middle position of the top of the circuit board 10 , so that the pressing plate 9 can be stably pressed against the middle position of the top of each circuit board 10 .
