Technical Field

The present invention relates to a gold plating suspension device having an impact buffering structure, and more particularly, to a gold plating suspension device having an impact buffering structure, which transfers a hanger at a uniform speed, reduces noise and impact generated during transfer, and forms a uniform gold plating layer on a substrate.

Background

In general, the manufacture of printed circuit boards is an aggregate of numerous processes, the steps of which are also extremely complex. The gold plating process, i.e., the metallization process, plays a central role in providing current and voltage to electrical components. Further, recently, printed circuit boards have been on the trend of being light, thin, short, and small, and the sizes of via holes for accessing metal wires and electronic components have been gradually reduced, which requires that gold plating be performed more uniformly. In the gold plating process of the printed wiring board, a method of forming a grain layer by electroless gold plating and then forming a metal layer by electrolytic gold plating is generally used for forming a circuit or a gold plating via. In order to implement the above fixing process, a technique for transferring a printed circuit board is disclosed, such as Korean registration No. 10-2001-.

As described above, when gold plating is performed on a printed circuit board, the hanger is moved along the guide rail by the driving device, the hanger is provided with the jig to which the printed circuit board is fixed, and the hanger and the printed circuit board are simultaneously moved by the driving of the driving device in a state where the printed circuit board is immersed in the water tank filled with the gold plating solution to form a uniform gold plating layer.

However, the conventional printed circuit board transfer structure has disadvantages in that: the hanger and the guide rail are coupled by the rack to move, and in the moving process, vibration or shaking is generated by meshing between the gears, the vibration is transmitted to the hanger, and parts of the hanger are loosened, so that the maintenance is required to be repeated. Also, the following serious drawbacks often occur: the vibration is transmitted to the jig combined with the hanger and the printed circuit board, causing the printed circuit board to be separated from the jig or the gold plating to be unevenly formed.

The above-described invention is a background art to which the present invention pertains, and does not mean a conventional art.

Also, the following terms are terms defined in consideration of functions of the present invention, which are according to the purpose or convention of users, operators, or are different. Therefore, the terms are to be defined according to the entire contents of the present specification.

The scope of the present invention is not limited to the following examples, which are intended to provide examples only, and various embodiments achieved by the technical idea can be provided.

As shown in the drawings, a suspension device for gold plating 10 having an impact buffering structure according to the present invention (hereinafter, referred to as a "suspension device for gold plating" for convenience) provides a suspension device to be moved by a transfer device composed of a guide platform 200, a rail housing 300, the guide platform 200 being screwed or welded along the outer surface of the water tub 100 and having a guide wall 210 integrally formed at the upper side; the guide frame 300 is installed on the upper portion of the guide platform 200, and includes a driving motor 320 for rotating the plurality of driving gears 310 and the plurality of driving gears 310, thereby moving and fixing the jig 400 on which the substrate immersed in the water bath 100 is fixed.

The suspension device 10 for gold plating according to the present invention is composed of a transfer frame 20, a fixed block 30, an elastic spring 40, a terminal panel 50, a base plate 60, a support portion 70, and a guide portion 80.

The rail housing 300 is provided with the driving motor 320 and the driving gear 310 at a predetermined interval along the longitudinal direction thereof to transfer the gold plating suspension 10 and the printed circuit board.

The transfer frame 20 is made of a metal material, has a rack portion 21 on a bottom surface thereof so as to be guided by a plurality of driving gears 310 provided on an upper surface of the rail frame 300 to move, has a plurality of locking holes 22 formed on the upper surface thereof, and has a lifting long hole 23 formed on a side surface thereof to communicate with the locking holes 22.

The locking holes 22 and the long lifting holes 23 are formed at regular intervals along the longitudinal direction of the transfer frame 20.

At this time, as shown in fig. 4, a long hooking groove 231 is further formed at one end of the long elevation hole 23 so that the support bush 32 is hooked and elevated.

Wherein, preferably, the hooking elongated slot 231 communicates with the side surface.

The fixed block 30 is inserted into the long elevation hole 23 in an elevation manner, and a connection shaft 31 on which a support bush 32 is disposed is formed at one end.

The support bush 32 is fixed by welding or screwing after being inserted into the connecting shaft 31, and is disposed in the hook long groove 231 to prevent the connecting shaft 31 from being separated from the long elevation hole 23.

As shown in fig. 1, the fixing blocks 30 are provided in the transfer frame 20 so as to be respectively caught in the elevation long holes 23.

The elastic spring 40 is inserted into the locking hole 22 and presses the connecting shaft 31 disposed in the long elevation hole 23.

The terminal panel 50 is connected to the fixing blocks 30, is fixed to the fixing blocks 30 by being screwed, and has one end formed with a plurality of protruding panels in one piece, so that the protruding panels press the elastic springs 40.

The protruding panel supports the connection shaft 31, is inserted into the locking hole 22, and has an upper end portion pressing an upper portion of the elastic spring 40 protruding from the locking hole 22.

The base plate 60 has a plurality of fixing blocks 30 fixed to the upper surface thereof by screws or welding while maintaining a predetermined interval therebetween, and a plurality of upper rollers 61 on the bottom surface thereof for hooking and guiding the fixing blocks to the outer surface of the guide wall 210.

The support part 70 is composed of a fixing plate 71 screwed to one side of the base plate 60 and a support plate 72 integrally formed at a lower portion of the fixing plate 71.

As shown in fig. 6, the fixing plate 71 and the support plate 72 face the inner side surface of the guide wall 210.

The guide portion 80 is composed of a guide plate 81 formed at a lower portion of the support plate 72, a connection plate 82 formed at a side surface of the guide plate 81 to fix the jig 400, and a lower roller 83 formed at an upper surface of the guide plate 81 to be guided to a side surface of the guide table 200.

The jig 400 is composed of a frame or a frame having a plurality of chucks, and moves in a state where the chucks are fixed with the printed circuit board, and the jig 400 or the printed circuit board fixed to the jig 400 is immersed in the water tank 100 filled with the gold plating solution.

At this time, one end of the end panel 50 presses the elastic spring 40 and is disposed at an upper portion of the transfer frame 20 so that an elastic space (S) is formed between the end panel 50 and an upper surface of the transfer frame 20, thereby moving the fixed block 30 and the guide 80 up and down to a height as shown in the drawing of the elastic space (S).

Preferably, guide protrusions are formed on both sides of the guide wall 210, and the upper roller 61 and the lower roller 83 further form an annular guide groove to be caught by the guide protrusions and guided, thereby preventing the gold plating hanger 10 from being separated from or deviated from the driving gear 310 when hooking or popping occurs during movement.

The guide rail groove is further locked with a U-shaped elastic buffering hose so as to be buffered when collision occurs with the guide rail protrusion, and optimally, the inner side surface of the elastic buffering hose is further locked with a ball bearing so as to reduce friction between the elastic buffering hose and the guide rail protrusion.

Hereinafter, the suspension 10 for gold plating having the shock absorbing structure is described in an activated state. First, in a state where the chuck of the jig 400 is hooked and fixed to the printed circuit board, the printed circuit board is immersed in the water tank 100 filled with the gold plating solution, and the driving gear 310 is engaged with the rack portion 21, the driving motor 320 is started to rotate the driving gear 310, and the gold plating suspension 10 and the printed circuit board move along with the gold plating tank to form a gold plating layer on the printed circuit board, thereby completing a series of steps.

At this time, as the weight of the fixing block 30, the base plate 60, the supporting portion 70, the guide portion 80, and the end panel 50 from the printed circuit board, the jig 400, and the gold plating suspension 10 presses the elastic spring 40, the elastic spring 40 sequentially presses the connecting shaft 31, and the connecting shaft 31 presses the transfer frame 20, so that the contact force between the transfer frame 20 and the driving gear 310 is increased to transfer at a uniform speed, and noise generated when transferring through the elastic spring 40 can be reduced. When the rack portion 21 and the driving gear 310 are hooked or flicked during the transfer, the elastic spring 40 can absorb the impact caused by the hooking or flicking.

Further, when the rack portion 21 and the driving gear 310 are caught or hooked to be flicked during the transfer, the connecting shaft 31 and the hook bushing are lifted and lowered along the lifting long hole 23 and the hook long groove 231, and are restored by the pressing force of the elastic spring 40, so that the impact is buffered, and the connecting shaft 31 is restored by the elasticity and fixed to the fixing block 30 without being lifted and lowered, so that the problem of bending or breaking caused by the accumulation of the impact on the connecting shaft 31 can be prevented.

A magnetic strip may be further inserted into the rack portion 21, and the drive gear 310 may be pressed and attached by the gold plating hanger 10 by the magnetic force of the magnetic strip.

As shown in fig. 7, the connection shaft 31 further sandwiches a buffer elastic tube 311, a plurality of coupling grooves 312 are formed on the outer surface of the buffer elastic tube 311, and the ball bearings 313 are further locked by the coupling grooves 312.

That is, in order to prevent the connecting shaft 31 from colliding with the long lifting holes when the connecting shaft is lifted up and down by vibration during the transfer, the connecting shaft 31 is sandwiched by the elastic buffer tube 311 made of an elastic synthetic resin material, and the impact due to the collision is buffered, thereby preventing the friction from occurring with the long lifting holes 23 during the lifting up and down by the ball bearings 313.

As shown in fig. 8, the vibrating portion 24 is further screwed or welded to the upper surface of the end panel 50 of the transfer frame 20.

The vibration part 24 is a vibrator, and the vibration of the vibration part 24 is transmitted to the jig 400 and the printed circuit board, and is transmitted to the transfer frame 20 while forming a uniform gold-plated layer on the printed circuit board, so as to prevent the rack 21 and the driving gear 310 from being caught.

As shown in fig. 9, a hooking long groove 231 is further formed at one end of the long lifting hole 23 to facilitate hooking of the support bush 32, and a friction surface 231a 'of the hooking long groove 231 further forms a lifting roller 231a' to prevent friction from occurring during lifting of the support bush 32 and to prevent the support bush 32 from being hooked or rubbed by the friction surface 231a during lifting of the support bush 32 together with the connecting shaft 31 due to impact and vibration.

As shown in fig. 10, a uniform pressing device 90 is further provided to sense the position of the gold plating hanger 10 and press the elastic spring 40 when the gold plating hanger is flicked or hooked during the transfer process, thereby increasing the adhesion force between the transfer frame 20 and the driving gear 310 and preventing the separation. The uniform pressing device 90 is composed of a pressing cylinder 91 provided on the end panel 50, a position sensing sensor 92 formed on the support plate 72, and a control unit 93 formed on the gold plating suspension device 10, and configured to receive a signal transmitted from the position sensing sensor 92 and drive the pressing cylinder 91. The pressing shaft of the pressing cylinder 91 further forms a pressing panel 911 to press the upper portion of the elastic spring 40.

That is, when the position sensor 92 senses that the position is higher than the set height of the guide wall 210 during the traveling, a signal is transmitted to the control unit 93, and the control unit 93 activates the pressing cylinder 91 to press the elastic spring 40, so that the rack 21 of the transfer frame 20 is brought into close contact with the drive gear 310, thereby returning the position of the gold plating suspension 10.

The gold plating suspension device 10 is preferably further provided with a wireless transmission unit for receiving and transmitting a signal transmitted from the control unit 93, and is preferably repaired after being recognized when a hooking or spreading phenomenon occurs during the travel of an operator.

As described above, one embodiment of the present invention is merely an example, and it will be understood by those skilled in the art of the present invention that various modifications may be made and other embodiments equivalent thereto may be derived.
