Description
Technical field
The present invention relates to capacitor production equipment fields, and in particular to the encapsulating device for capacitor.
Background technique
Capacitor is one of the electronic component largely used in electronic equipment, and capacitor is equivalent to disconnected in DC circuit
Road.Simplest capacitor is made of the pole plate at both ends and intermediate insulation dielectric.In order to improve the safety system of capacitor
Number injects casting glue on capacitive surface to seal up capacitor, to guarantee the peace in the service life and running engineering of capacitor
Entirely.
Existing encapsulating device includes tank body and cover, is arranged grip slipper in tank body, and when encapsulating grips capacitor
On grip slipper, encapsulating pipe is then corresponded into every block of capacitor, injects casting glue from encapsulating pipe when encapsulating, casting glue when encapsulating
It is flowed down from capacitive head or encapsulating pipe is located at capacitor one side and is potted, casting glue runs down on capacitor automatically and is potted
Shi Rongyi flowing is uneven, and encapsulating pipe is located at capacitor side, is only potted to a side of capacitor, the encapsulating of capacitor
Unevenly, and casting glue bubble easy to form in flow process, bubble, which stays in inside encapsulating layer, will affect heating conduction, when
It can make air bubble expansion after capacitor is heated and the accidents such as explosion occur.
Summary of the invention
The invention is intended to provide a kind of encapsulating device for capacitor, uniformly to coat casting glue on capacitor and reduce filling
Bubble in sealing.
The encapsulating device for capacitor in this programme, including tank body and the cover that top of the tank is arranged in, the cover
On offer gas outlet, the interior bottom of the tank body is equipped with multiple grip slippers, and unidirectional air outlet valve is equipped at the gas outlet, described
Tank interior is additionally provided with driving wheel and multiple driven wheels, and the driven wheel is located at driving wheel circumferentially and is turned by driving wheel drive
Dynamic, equal bias is connected with eccentric rod on the driven wheel, and the eccentric rod is equipped with for the injected rubber hose to capacitor encapsulating, described
Injected rubber hose is located at the lateral of grip slipper, the flabellum of fixed oriented gas outlet air draft on the eccentric rod.
The working principle and beneficial effect of this programme is: before encapsulating, capacitor is fixed in tank body by grip slipper, will be electric
After the completion of holding clamping, sealing of tank cover is on tank body；When being potted, circumferential driven wheel is driven in driving wheel rotation process
Rotation drives eccentric rod to rotate around capacitor, while the injected rubber hose on eccentric rod is arranged in eccentric rod when driven wheel rotates
Rotation is rotated around capacitor, and injected rubber hose coats casting glue to capacitor, is rotated to capacitor coating casting glue simultaneously in eccentric rod, eccentric rod
Flabellum rotation thereon is driven, the intracorporal air of tank is discharged the fan blade rotating movable property raw air-flow to gas outlet direction from gas outlet.
When driving wheel as power drive multiple driven wheels rotation when, realize using the same power to multiple capacitors into
Power is saved in row encapsulating, and injected rubber hose carries out rotary encapsulating to capacitor as eccentric rod is rotated, and rotary encapsulating can will fill
Sealing is coated on the circumferential surface of capacitor, while driving wheel rotation can simultaneously be potted multiple capacitors, and capacitor is made to coat encapsulating
Glue more evenly, improves the efficiency of capacitor casting glue coating；While coating casting glue to capacitor, the raw air-flow of fan blade rotating movable property
It is discharged from gas outlet, the intracorporal air of drain tank while coating casting glue to capacitor, when flabellum does not rotate, at gas outlet
Unidirectional air outlet valve close to avoid tank body outside air enter, from gas outlet be discharged air after can be reduced the intracorporal air of tank,
Fan blade rotating kinetic energy on the more eccentric rods continuously intracorporal air of drain tank, makes to form negative pressure in tank body, when being formed in tank body
After subnormal ambient, the bubble in casting glue can rupture, and reduce in potting process in casting glue bubble to reduce security risk.
Further, cavity is equipped in the eccentric rod, the injected rubber hose is located in cavity, the injected rubber hose and cavity inner wall
Between be equipped with insulating layer.
The heat that injected rubber hose loses in potting process is reduced, injected rubber hose temperature in potting process is avoided to reduce and block
Injected rubber hose
Further, it is equipped with rotary cylinder in the tank body, it is empty to form gas storage between the piston block and cylinder bottom of the rotary cylinder
Between, the cylinder bottom is equipped with air inlet, is equipped with breather cheek valve at the air inlet, the rotating bar of the rotary cylinder is equipped with
Sector rack is equipped with the shifting block that can toggle it to sector rack on the eccentric rod.
Existing rotary cylinder includes piston block and piston rod, and piston rod one end is connect with piston block, piston rod it is another
End is rotatably assorted and has eccentric wheel, and rotating bar is fixedly connected on eccentric wheel, and the interior bottom that piston block is not connected with piston rod side is cylinder bottom,
Under primary condition, piston block is located at cylinder bottom, in the design, when the shifting block on any one eccentric rod turns to sector rack
When side, shifting block stirs sector rack, and rotating bar rotation is driven when sector rack rotates, and rotating bar passes the power of rotation
It is delivered to eccentric wheel, allows eccentric wheel that piston rod is driven to haul piston block and leaves cylinder bottom, so that the intracorporal air of tank is pumped into cylinder
In, it extracts the air in tank body out, reduces the intracorporal air of tank, when sector rack is stirred in more eccentric rod rotations, every bias
Shifting block on bar all stirs sector rack, and rotating bar can be allowed to be continued for rotating, so that constantly extraction tank is intracorporal
Air, the time that the piston block of rotary cylinder is moved up from cylinder bottom in the design are an encapsulating period, when having in casting glue
When having bubble, with the reduction of air in tank body, negative pressure is formed in tank body, it can be by the gas in casting glue during encapsulating
Bubble removes, and avoids remaining bubble in capacitor encapsulating, and the breather cheek valve in air inlet can prevent the air being pumped into cylinder again
It enters in tank body.
Further, the rotating bar is communicated to outside tank body, and outlet passageway is offered in the rotating bar, and the outlet is logical
Road is connected to outside gas storage space and tank body inside rotary cylinder.
The air for being pumped into rotary cylinder is rejected to outside tank body by rotating bar, reaches the mesh to tank interior pumping
, while tank body can be evacuated repeatedly, the intracorporal air of tank is reduced, to extract the air in casting glue in bubble out, is reduced
The bubble of casting glue.
Further, the outlet passageway is located at the exit outside tank body equipped with pressure valve.
When the air that cylinder is extracted out from tank body make internal cylinder pressure increase after, due in rotary cylinder also continue into
Enter air, air pressure supports and opens pressure valve, and the air in cylinder can be automatically drained out.
Further, it is located on the cover on same circumference and is uniformly arranged multiple gas outlets, the gas outlet and eccentric rod
It corresponds.
When more eccentric rod rotations drive flabellum rotation, flabellum rotation excludes the intracorporal air of tank from gas outlet, out
Port corresponds with eccentric rod and the raw air of fan blade rotating movable property can be discharged in time, while air is discharged in multiple gas outlets simultaneously
It can accelerate the discharge of tank interior, quickly reduce the intracorporal air of tank, extract the air that bubble carries in casting glue out, reduce encapsulating
Bubble in glue.
