Description

A kind of barrel plating formula copper facing equipment
Technical field
Electroplating device field is the utility model is related to, more particularly to a kind of barrel plating formula copper facing equipment.
Background technology
Copper-plating technique is the process for plating a thin layer layers of copper on some metal surfaces using electrolysis principle, in production application Middle electroplating technology copper-plating technique has great significance, by can be improved in metal surface electro-coppering metal corrosion resistance, Electric conductivity and having improved aesthetic appearance effect etc., such as the Chinese patent that notification number is CN205501443U disclose a kind of barrel plating rolling Cylinder, including fixed mount, in fixed mount be used for contain workpiece cylinder, driving cylinder rotation power set, passing power Transmission device and give electric installation for power supply;Cylinder includes stack shell, two first gears positioned at stack shell both sides, positioned at the Two fixed sides on the outside of one gear, positioned at stack shell inwall to reduce the projection of workpiece and cylinder contact area, two are solid Determine to offer three first through hole relatively in the middle part of side plate, wearing a middle first through hole to electric installation thinks that cylinder is powered, and passes Dynamic device wears middle first through hole to drive cylinder to rotate, and two side plate tops are relatively set with the extension for supplying outside driving hanging Part.Workpiece is contacted and is changed to a contact, is advantageous to protect roller, barrel plating effect good by the roller with the contact site of roller by face, And peg is not easy burn into and advantageously reduces potential safety hazard.
In actual use, after the completion of plating, transfer plating piece needs roller and drive device integrally proposing electroplating bath, It is more troublesome.
Utility model content
The purpose of this utility model is to provide a kind of barrel plating formula copper facing equipment, has and is easy to take out the excellent of plating piece in roller Point.
Above-mentioned technical purpose of the present utility model technical scheme is that:
A kind of barrel plating formula copper facing equipment, including electroplating bath and the roller that is rotatably connected in electroplating bath, on the roller The drive device of its rotation of driving is provided with, the roller includes barrel shell and plating piece box, and the roller side is offered for plating piece The opening that box plug connects, offer some through holes on the plating piece box and roller, set on the plating piece box it is restricted its from opening The locating part of mouthful abjection, is provided with the hoisting device for slinging plating piece box from opening on the electroplating bath.
By in this way, it is necessary to when taking out the plating piece in roller after the plating of plating piece is completed, without by whole roller Lift, plating piece box is sling out of roller by hoisting device after only need to untiing locating part, subsequently takes out plating piece out of plating piece box , it is convenient and strength-saving, and certain energy consumption can be reduced.
The utility model is further set:It is provided with the plating piece box and carries block, the locating part is connected to including sliding Motion bar on plating piece box, the neck coordinated with motion bar is offered on the barrel shell, is set between the locating part and motion bar It is equipped with and keeps motion bar and the first spring of neck clamping.
So when needing to take out plating piece box, only need to press and overcome the elastic force of the first spring to be compressed it, motion bar from Plating piece box can be lifted by being removed in neck, and similarly motion bar can be in the first spring after plating piece box is placed in barrel shell and unclamped Elastic force effect under be caught in again in neck, it is simple in construction.
The utility model is further set:The hoisting device includes the suspension bracket fixed with electroplating bath, and the suspension bracket rises Drop is connected with suspension rod, and the actuator of its lifting of driving is fixed with the suspension rod, is provided with the suspension rod and carries block for clamping And the fixture for driving motion bar to move, it is described that to carry block section T-shaped.
What section was T-shaped first, which carry block, easily facilitates and carries, and drives suspension rod to move down by actuator, and clamped by fixture Carry block and above proposed operation, and promote motion bar one end to overcome the elastic force of the first spring to realize plating during clamp Part box is untied with barrel shell clamping, subsequently directly can above be carried, and without manual operation, operation is more convenient to be saved whole process Power.
The utility model is further set:The actuator includes the first motor being fixed on suspension rod, first electricity Rotating wheel is provided with the output shaft of machine, the rack engaged with rotating wheel is fixed with the suspension bracket.
Because rack is fixed on suspension bracket, therefore suspension rod can be driven to lift when motor rotates, realized plating piece box from cylinder Shell proposes that without artificially going to operate, operation is more laborsaving for operation.
The utility model is further set:The fixture includes the fixed plate fixed with suspension rod, is set in the fixed plate There is projection, the both sides of the projection are provided with the chuck be hinged with it, and sliding block is fixed with the chuck, the fixed plate On offer the slide opening slided for sliding block, stretch to be connected with the fixed plate and fixed with projection and drive pushing away for chuck folding Bar.
It is sliding by promoting push rod movement to carry block to drive chuck to clamp so after suspension rod is dropped into the position of needs On the one hand hole coordinates with sliding block can play a part of guiding, can also play spacing effect in addition, avoid chuck from rotating excessive Situation occur.
The utility model is further set:It is provided between the bottom of the push rod and fixed plate outside driving push rod and moves reset Second spring, be provided between the push rod and fixed plate and keep chuck to be in the locking piece of clamped condition.
When push rod is moved to chuck clamping and carries block, push rod is locked by locking piece so that chuck can be stablized Be in clamp position, avoid occurring situation about releasing during plating piece box is lifted, and after locking piece is untied, push rod meeting Cause chuck to be in open mode in the elastic reset of second spring, be easy to the gripping of next time.
The utility model is further set:The locking piece includes the snap-on being arranged on push rod, is opened in the fixed plate Provided with snap-on clamping and for the fixing hole of its evagination.
When push rod is moved to chuck clamping and carries block, snap-on is in correspondence position with fixing hole, and snap-on is under elastic force effect Be caught in and pass fixing hole, it is necessary to unlock state when need to only press snap-on, it is simple in construction and easy to operate.
The utility model is further set:The plating piece box includes box body and cover plate, and the cover plate passes through screw with box body It is fixed.
When placing the abjection of internal plating piece to cover box body by cover plate, then needing to take out or place plating piece, only need to unclamp Screw.
