Description
Technical field
The present invention relates to a kind of electric energy meter production technologies, specially take control intelligent electric energy meter production technology, belong to ammeter life
Produce technical field.
Background technology
Ammeter, the abbreviation of electric energy meter is the instrument for measuring electric energy, also known as kilowatt-hour meter, energy meter, electric energy meter, kilowatt small
When table, refer to the instrument for measuring various electrical quantities.Ammeter is divided into ammeter, voltmeter, electric energy meter, and ammeter is electric in measuring circuit
The tool of size is flowed, voltmeter is a kind of instrument for measuring voltage, and electric energy meter is the instrument for measuring electric energy.Earliest electric energy
Table (also referred to as ammeter) be 1881 according to made of electrolysis principle, it is very stupid although this electric energy meter every weighs tens kilograms
Weight, and the guarantee without precision, still, were still valued by people and were praised by an invention of great significance as scientific and technological circle at that time
It raises, and soon employs it in engineering, with the development of science and technology, 1888, the discovery and application of alternating current, and to
The development of electric energy meter proposes new requirement.By the effort of scientist, induction type electric energy meter is born.Due to inductive power
Table has the series of advantages such as simple in structure, safe operation, inexpensive, durable and easy to repair and batch production, so development is very
Soon.The function that intelligent electric meter has has been embodied on original Semi-intelligent Modular formula electric energy meter, is national grid nothing but
The function of network communication and photoelectric communication is mixed to ammeter again, the general service life of table that generated electricity in the form of professional standard is 6 years,
Once to be examined, looked after and guided according to the every 6 years ammeters of national regulation, replaced and etc., to ensure Electrical Safety.In ammeter
In production, take control intelligence there is presently no a kind of suitable flow line production dedicated for single-phase charge-controlled intelligent electric meter production
Electric energy meter production technology.
Invention content
The purpose of the present invention be that provide to solve the above-mentioned problems a kind of suitable flow line production dedicated for
Single-phase charge-controlled intelligent electric meter production takes control intelligent electric energy meter production technology.
The present invention is achieved through the following technical solutions above-mentioned purpose：
Take control intelligent electric energy meter production technology, include the following steps：First, mainboard silk-screen, it is right using full-automatic vision printing equipment

2-3 DEG C of warm area slope/S, cooling zone are produced when being less than 5 DEG C/S, in production process, are detected at any time using visual inspection, core
Do not conform to lattice point to what machine tested out, it is labelled at underproof position, to the unqualified place of discovery, carry out repair welding；4th,
Wiring board after Reflow Soldering is mounted on fixture by plug-in unit, is then inserted into crystal oscillator, discharge tube, electrolysis electricity respectively in different station
Appearance, thermistor, varistor, transformer；5th, wave-soldering, using dual waves welding machine to complete previous step wiring board into
Row wave-soldering, it is 130 DEG C that wave-soldering temperature region, which preheats 1 area's temperature, and 2 area's temperature of preheating are 140 DEG C, and 3 area's temperature of preheating are 150
DEG C, speed chain 1500mm/min；6th, it cleans, polylith workpiece is put into rinse bath, carried out using supersonic wave cleaning machine clear
It washes, is dried after the completion of cleaning；7th, repair welding, the wiring board after detection cleaning check emphatically rosin joint, even solder skip, weldering, pin
It is excessively high（More than 2mm）, it is found that rosin joint, solder skip are modified in time using repair welding, then with constant temperature electric iron different station according to
It is secondary that crystal oscillator, switch, battery, key of uncapping, 12 foot sockets, backlight, 4 foot sockets are respectively welded, liquid crystal display is then fixed on finger
Positioning is put, then drags weldering liquid crystal display pin, LED light, then cuts foot, labelling；8th, it checks, first checks the welding of pcb board component
Position, polarity, dialysance, re-inspection component whether there is damaged, missing, crooked, and whether reexamine each solder joint bright and clean, full,
Rosin joint, solder skip are whether there is, after confirming qualification, the dispensing at crystal oscillator, you can be packaged into finished product.The environment temperature of entire production technology
It it is 23 DEG C ± 3 DEG C, humidity is 50%RH ± 10%RH.The operating personnel of entire production technology are required to wear antistatic wrist strap.It is whole
It is first produced in a production technology using more jigsaw, then carries out scoreboard after mainboard silk-screen, wave-soldering respectively.The plug-in unit step
In, the different model of same electronic device is inserted into different station.In the plug-in unit step, it should ensure that component pin is not curved
In the case of song, component need to be inserted into bottom, and electrolytic capacitor needs to pay attention to polarity, and the hypographous part of pcb board silk-screen corresponds to electrolysis
The cathode of capacitance, thermistor will be kept upright, ontology it is small be partially toward transformer, varistor is kept upright, and not fallen
To transformer, thermistor, the pin of transformer is corresponding with the position in hole on PCB.In the wave-soldering, scaling powder selection dimension
Special idol GW9810A-5 types.In the wave-soldering, according to the determining spray velocity of the width+50 of jig, jig width -10 determines spray
Mist width.In the cleaning step, according to Wei Te idols GW804：Wei Te idols GW9810A-5=3:Cleaning agent is poured into rinse bath by 1.
The beneficial effects of the invention are as follows：The component of different model is subjected to grafting in different station respectively, to greatest extent
It avoids leakage to insert, misplug, and the design of pure pipeline system production, ensure that the high efficiency of production, the production technology multiple step format
Operation, convenient for production, production process is checked at any time, it is therefore prevented that batch is bad.In addition, more jigsaw are first used in production technology
Production, scoreboard is then carried out after mainboard silk-screen, wave-soldering, improves production efficiency respectively.
