Abstract
An application of spot welding technique to the down-lead connection of slice vibrant electrical loop winding, including the welding of the down-lead and double-faced PCB board. This invention does not need welding materials and plumbum; the enamel wire welding does not need pre-removing enamel cover and stannum soaking pre-processing, and reduces the industrial pollution caused by using lacquer removing solution and welding assistant. This invention uses half-mechanization of electronic spot welding machine, avoids the weak points of the hand welding operation, and effectively prevent of bad contact phenomenon. Therefore, this invention not only reduces the cost, but also improves the working efficiency and greatly increases the eligible ratio of the welding.
Description
[technical field]
What the present invention relates to is that electronic spot-welding technology is used, the especially application of electronic spot-welding technology on chip vibrating motor coil winding leads connects.
[technical background]
The chip vibrating motor is called button or monetary apparatus vibrating motor again.Be mainly used in beauty making appliances such as the noiseless alarm of vibration of mobile phone or massager, massage cushion, vibromassage rod.
The chip vibrating motor is a kind of of direct current machine, comprising: brush chip vibrating motor and brushless chip vibrating motor are arranged.It is coil windings that the rotor of brush chip vibrating motor is arranged, and the stator of brushless chip vibrating motor is a coil windings.
For satisfying the flattening structural requirement of chip vibrating motor, the coil windings of rotor no matter, or the coil windings of stator all is floor plan, forms by 2 to 4 hollow tread flaking coil groups.Be that example is described as follows with 3 common coil windings now: 3 coil windings are bonded to the assigned address on a circuitron (PCB) plate earlier; This two-sided pcb board overall dimension is pressed the specification processing of rotor or stator; By the interconnection requirement of 3 coil windings, in the wiring of the one side designed lines of two-sided pcb board and leave pad; Each coil windings has 2 lead-in wires, and 3 coil windings have 6 lead-in wires; Adopt plumber's solder with electric iron with 6 lead-in wires one by one correspondence be soldered on the relevant pad, thereby finish the interconnection requirement of these 3 groups of coil windings.In addition, also designed corresponding line, pad etc.,, the chip vibrating motor has been devoted oneself to work by pcb board another side pad or with brush contact conduction or connect motor power with lead in addition at the another side of two-sided pcb board.The weldering of slicker solder material is adopted in the connection of above-mentioned coil windings lead-in wire usually, based on the electric iron manual operations.Its advantage is that technology is simply ripe, and cost is low.But there is following defective in it:
1, coil windings adopts the enamelled wire coiling usually, before the weldering of lead-in wire slicker solder material, must carry out the coating removal skin to lead ends earlier and handle, and copper cash behind the coating removal skin and pad can be welded together.The coating removal skin is handled had both increased operational sequence, also can improve processing charges.
If 2 remove lead-in wire coating removal skin treatment process from, adopt special varnish envelope curve coiling winding, because the more common enamelled wire price of special varnish envelope curve is expensive, therefore can increase cost.
3, manual slicker solder material welding operation, the piling height of solder joint is wayward, can cause wire bonds lack of standardization, inconsistent, thereby influences the qualification rate of wire bonds.
4, required scaling powder, the cleaning agent of slicker solder material weldering all belongs to chemicals, and it uses the pollution that can cause undoubtedly environment.
[summary of the invention]
The objective of the invention is the deficiency that manual welding exists at above-mentioned coil windings lead-in wire, the application of electronic spot-welding technology on chip vibrating motor coil winding leads connects is provided, it can overcome the defective of prior art.
The application of electronic spot-welding technology of the present invention on chip vibrating motor coil winding leads connects comprises the welding between the Copper Foil pad on lead-in wire and the two-sided pcb board.
The application principle of electronic spot-welding technology of the present invention on chip vibrating motor coil winding leads connects is: by the tip-shape parallel double electrode of the band chopper of electronic spot welder; affact the enamelled wire head surface of coil windings lead-in wire; rely on this mechanical pressure to puncture the coat of paint protective layer on enamelled wire surface; finish the ohmic contact of parallel double electrode and the end of a thread copper core; then under the low-voltage, high-current impulse action; make the lead end copper core heating power under the pressing of parallel double electrode; instantaneous time just reaches the high temperature of copper core fusing, makes lead end directly and the Copper Foil pad melted join on the pcb board.For Copper Foil pad molten solder coupling on the enamelled wire lead end that adapts to different thicknesses line footpath and the pcb board, can between 0-2V, adjust low-voltage, high-current pulse amplitude (Pulse Amplitude); Also can between 0-20ms, adjust pulse conduction duration (Pulse Duration).
The present invention compared with prior art has the following advantages and effect:
One,, thoroughly unleaded fully without scolder;
Two, the enamelled wire welding need not prior coating removal skin and wicking preliminary treatment, has not only reduced production cost, has improved work efficiency, also can reduce the industrial pollution because of using chemicals such as paint remover, scaling powder to cause;
Three, use the semi-mechanized operation of electronic spot welder, overcome the defective that hand-held electric iron welding operation exists, effectively prevented phenomenons such as the common rosin joint of manual welding, loose contact, both improved work efficiency, improved solder yield again greatly;
Four, owing to, just do not have the accumulation of scolder, reduced the height space that solder joint occupies, the microminaturization of favourable product without scolder.
The concrete grammar of the application of electronic spot-welding technology of the present invention on chip vibrating motor coil winding leads connects is provided in detail by following examples.
