Plating tank cathode moving device
Technical field
The present invention relates to a kind of plating tank, is plating tank to make electroplating parts carry out the cathode moving device of horizontal reciprocating movement specifically.
Background technology
At present, in electroplating industry, plating tank uses the most a kind of electroplating device, and it can implement electroplating activity by the electroplate liquid in groove to the electroplated workpiece hung on wherein.Traditional plating tank is all that opening part arranges copper bar at its upper end, then the workpiece suspension electroplated by band, on copper bar, makes workpiece be sunken in electroplate liquid, and the Main Function hanging workpiece prevents from contacting between workpiece with plating tank cell body, avoid plating not exclusively, thus improve electroplating quality.But, when the workpiece of electroplated be sunken to electroplate in electroplate liquid time, workpiece surface can produce a large amount of bubbles, if can not remove bubble timely, then the workpiece surface electroplated can be caused to have gas bubbles left, electroplate uneven, thus affect electroplating quality.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of plating tank cathode moving device, adopts this device, can remove the bubble on electroplating parts surface in time, makes workpiece surface electroplate evenly, improves electroplating quality.
For solving the problem, take following scheme:
Plating tank cathode moving device of the present invention comprises cell body, and there is copper bar at cell body upper end open place.Be characterized in that all there is pulley both sides, described cell body upper end open place, pulley all has the groove of annular, described copper bar is put in the groove of two pulleys.There is bearing side, described cell body upper end, bearing has motor, the output terminal of motor is fixed with driving wheel.One end of described copper bar is fixed with Connection Block, Connection Block is fixed with downward orienting lug, orienting lug has vertical groove.Described driving wheel has guiding bolt in the position away from the center of circle, and this guiding bolt stretches in the groove of orienting lug.
Further improvement of the present invention scheme be on described guiding bolt cover have sliding sleeve, guiding bolt by between this sliding sleeve and orienting lug groove in being slidably matched.Like this, driving wheel can be reduced in rotation process, the friction between guiding bolt and orienting lug groove, reduce the damage of parts.
Further improvement project of the present invention described driving wheel has the hole for fixed guide bolt being no less than 2, and this some holes is all unequal to the distance in the driving wheel center of circle, can by these pore distributions on the line gradually far away in the driving wheel center of circle.Like this, be conducive to the motion amplitude increasing or reduce copper bar on cell body according to actual needs gradually, the scope of application is comparatively extensive.
Take such scheme, have the following advantages:
Because plating tank cathode moving device of the present invention has bearing in side, cell body upper end open place, bearing there is motor, the output terminal of motor is fixed with driving wheel, driving wheel has guiding bolt in the position away from the center of circle, and this guiding bolt stretches in the groove of the orienting lug being fixed on copper bar one end.Therefore, when machine operation, the guiding bolt driven on it slides up and down relative to orienting lug by the rotation of driving wheel, and orienting lug then does horizontal reciprocating movement with driving wheel, thus makes also to do horizontal reciprocating movement with orienting lug in the copper bar be fixedly connected with.Like this, when workpiece carries out electroplating activity, copper bar can drive suspension workpiece thereon to do horizontal reciprocating movement in electroplate liquid, and the bubble that workpiece surface produces is removed fast in movement, thus it is even to ensure that workpiece surface is electroplated, and improves electroplating quality.

Embodiment
As depicted in figs. 1 and 2, plating tank cathode moving device of the present invention comprises cell body 1 and copper bar 3, and all there is pulley 2 both sides, cell body 1 upper end open place, and the axis of two pulleys 2 is parallel to each other, and the line of two pulley 2 centerline and axis perpendicular.Described two pulleys 2 all have the groove of annular circumferentially, described copper bar 3 is placed in the groove of these two pulleys 2.There is bearing 9 side, described cell body 1 upper end in the outside of pulley 2, bearing 9 has motor 8, the output terminal of motor 8 is fixed with driving wheel 7, and the axis of driving wheel 7 parallels with the axis of pulley 2.One end of the corresponding motor 8 of described copper bar 3 is fixed with Connection Block 5, and Connection Block 5 is fixed with orienting lug 4, orienting lug 4 is positioned at the below of copper bar 3 axis, and orienting lug 4 has vertical groove 10.Described driving wheel 7 has guiding bolt 6 in the position away from the center of circle, the axis of guiding bolt 6 parallels with driving wheel 7 axis, and guiding bolt 6 stretches in the groove 10 of orienting lug 4.Guiding bolt 6 on cover have sliding sleeve 11, guiding bolt 6 by between this sliding sleeve 11 and orienting lug groove 10 in being slidably matched.Guiding bolt 6 stretches out one end outside orienting lug groove 10 can mounting nuts or jump ring, makes in use, slippage can not occur between orienting lug 4 and guiding bolt 6.
Wherein, described driving wheel 7 has the hole being no less than 2, this some holes can be blind hole, screw or through hole, and its effect is used to fixed guide bolt 6, and this some holes is all unequal to the distance in driving wheel 7 center of circle.For the ease of adjustment and operation, by these pore distributions on the line gradually far away in driving wheel 7 center of circle, thus can make when the bolt 6 that leads is arranged in different holes, copper bar 3 can obtain different transverse movement amplitudes.
During operation, open motor 8 power supply, driving wheel 7 rotates together with guiding bolt 6, guiding bolt 6 does moving up and down relative to orienting lug 4 in orienting lug groove 10, and orienting lug 4 does side-to-side movement relative to motor 8, thus drive the workpiece of copper bar 3 and upper suspension thereof to do bilateral reciprocation, make workpiece in electroplate liquid, remain regular kinestate, the bubble on its surface can be disposed fast and effectively, thus improves electroplating quality.
