Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1-4, the utility model provides a PCB electroplating hanger 100, which comprises a wall hanging component 1, a supporting wall 2, a side lever 3 and a bolt 4.

The wall hanging assembly 1 comprises a wall hanging 11, a fixed wall 12 fixed to the lower surface of the wall hanging 11 and extending along the length direction of the wall hanging 11, two adjusting walls 13 horizontally arranged and perpendicular to the two opposite ends of the fixed wall 12, a clamping wall 14 parallel to the fixed wall 12 and provided with two ends respectively sleeved on the two adjusting walls 13 to form sliding connection, and an adjusting spring 15 sleeved on the adjusting walls 13.

The adjusting wall 13 is fixed on the fixed wall 12, one end of the adjusting spring 15 is fixed on one end of the adjusting wall 13 far away from the fixed wall 12, the other end of the adjusting spring 15 is fixed on one side of the clamping wall 14 far away from the fixed wall 12, when the adjusting spring 15 is in a natural state, the clamping wall 14 abuts against the fixed wall 12 to form pre-pressure, and therefore automatic adjustment according to the plate thickness is facilitated when the top end of the PCB is clamped between the clamping wall 14 and the fixed wall 12.

Support wall 2 interval set up in hang wall 11 below and with hang wall 11 parallel arrangement, support wall 2 is close to one side of hanging wall 11 is sunken to form support groove 21, support groove 21 along being on a parallel with support wall 2 length direction's relative both sides, two support groove walls paste respectively promptly and are equipped with the conducting strip 22 that is used for being connected with electroplating device electricity, the both ends of support wall 2 are equipped with screw hole 23.

The side bars 3 comprise two and are respectively located at opposite ends of the fixed wall 12. The top of side lever 3 with fixed wall 12 fixed connection, the bottom of side lever 3 runs through support wall 2 and forms sliding connection, two one side that side lever 3 is close to each other all caves in and forms constant head tank 31, constant head tank 31 extends to the both ends of side lever 3 along the length direction of side lever 3, the relative both sides of constant head tank 31, two relative constant head tank wall laminating have rubber wall 32 promptly. The side bar 3 is in contact with the threaded hole 23, i.e. the side bar 3 passes at least partly through the threaded hole 23 when penetrating the support wall 2.

The bolt 4 is in threaded connection with the threaded hole 23 and abuts against the side rod 3, so that the side rod 3 can be locked and positioned.

When the PCB needs to be clamped for electroplating, the bolt 4 is loosened to enable the supporting wall 2 to be separated from the side rods 3, the left side and the right side of the PCB are inserted into the positioning grooves 31 of the two side rods 3 and are upwards inserted into the positioning grooves until the top side of the PCB is clamped between the clamping wall 14 and the fixed wall 12, the supporting wall 2 is sleeved on the side rods 3, the lower side of the PCB is abutted to the supporting groove 21, clamping on the four sides of the PCB is formed, deformation of the PCB caused by insufficient thickness and hardness is effectively prevented, electroplating uniformity is improved, and reliability is better.

In this embodiment, the cross section of constant head tank 31 by the tank bottom of constant head tank 31 diminishes to its notch direction gradually, and after this structure set up, when the left and right sides of PCB board presss from both sides respectively and locates the constant head tank 31, through rubber wall 32 contact PCB board, avoid causing the mar to PCB board both sides, simultaneously, because of the cross section of constant head tank 31 by the tank bottom of constant head tank 31 diminishes to its notch direction gradually, then the clamping-force of notch is bigger, and the clamping-effect is better, and constant head tank 31 inner area is bigger moreover for the PCB board inserts the part inside of constant head tank 31 can not be caused the surface fish tail and influence whole electroplating effect by the extrusion.

The conducting strip that sets up in the support groove 21 is buckled and is the elastic construction of U type, can realize on the one hand forming the electrode with the electricity of electroplating device, and on the other hand forms the elasticity centre gripping to the lower extreme of PCB board, does not need accurate counterpoint can more swiftly centre gripping PCB board, effectively improves the efficiency of supporting wall 21 installation.

In this embodiment, one side of the hanging wall 11, which is far away from the supporting wall 2, extends to form a hanging ring 5, so as to hang the whole PCB board electroplating hanger on the electroplating equipment.

The above embodiments of the present invention are only described, and it should be noted that, for those skilled in the art, modifications can be made without departing from the inventive concept, but these all fall into the protection scope of the present invention.
