Abstract
The invention discloses a manufacturing method of a diode and an automatic output device of the diode. The manufacturing method is mainly formed by nine steps, namely filling, welding, scouring, slivering, pre-drying, gluing, glue curing, compression molding and post-curing under certain conditions. The automatic output device used for achieving the process comprises a machine frame and is characterized in that delivery guide rails are arranged on the machine frame, a plurality of fixed shaft arranged at equal interval are arranged between the delivery guide rails, and an idler wheel or a bearing is sleeved on the shaft. A cooling frame parallel to the delivery guide rails is arranged right above delivery guide rails, and a plurality of cooling fans which are downwards to align to the delivery guide rails are installed on the cooling frame. Users do not need to wait when using the automatic output device which can directly enter a furnace, so that exposed time in the air is shortened, and pollution of foreign ion is reduced. Manual transit shipment is not needed when the automatic output device comes out of the furnace, so that personal factors are reduced, and labor time is saved.
Description
Technical field
The present invention relates to a kind of diode making process, specifically is to adopt filling, welding, pickling, sliver, preliminary drying, gluing, adhesive curing, compression molding, back to solidify the manufacturing approach that these nine steps constitute.In order to realize above method, the invention still further relates to a kind of automatic conveying device.
Background technology
Traditional preliminary drying technology is: the stainless steel disc that will fill product is placed on a transit wagon earlier, when treating the full baking oven of sliver (30 dish), one coils in baking oven of threading again; 150 ℃ of oven temperatures, 30 minutes time, and then one coil and take out; Loading onto transit wagon delivers between gluing; The shortcoming of this technology is: the time of coming out of the stove is longer, and intermediate link is more, and it is longer that the tube core that causes having cleaned is exposed to the airborne time; Receive dust in air and steam and stain, it is electrically bad that finished product is produced.
Summary of the invention
Main task of the present invention is to provide a kind of manufacturing process of diode, specifically is a kind ofly can effectively solve electrically bad diode manufacturing process of product.
In order to solve above technical problem, a kind of diode making process of the present invention is mainly solidified eight steps by filling, welding, pickling, sliver, preliminary drying, gluing, adhesive curing, compression molding, back and is constituted; It is characterized in that: in the preliminary drying operation, peak temperature in the stove is controlled at 203 ℃-216 ℃; The interior temperature of stove was controlled at 30 minutes greater than 150 ℃ time; After preliminary drying finishes; Temperature is controlled at 160～180 ℃ comes out of the stove, the product of coming out of the stove places on the automatic conveying device comes out of the stove, and directly delivers to glue process by automatic conveying device; In carrying the way, product temperature needs to be cooled to required 38 ℃-45 ℃ of gluing by automatic conveying device.
The present invention also provides a kind of automatic conveying device of realizing diode manufacturing process, comprises frame, it is characterized in that: frame is provided with a conveying, is provided with the fixed axis that some equidistance are arranged between the conveying, is set with roller or bearing on the axle; Directly over conveying, be provided with cooling support in parallel, the cooling fan of some downward aligning conveyings is installed on the cooling support.The invention has the advantages that:
1. use automatic conveying device need not wait for; Directly advance stove; Reduced the time that exposes in the air; Also reduced the pollution of foreign ion, had into the stove mode now and accomplish that sliver finishes to advance stove immediately, former mode is that card of every completion can advance stove (time interval reaches 10 minutes between first pallet and last pallet).
2. coming out of the stove is directly connected to the gluing station, accomplishes first in first out, has reduced the time that exposes in the air, has also reduced the pollution of foreign ion.
3. coming out of the stove need not artificial transfer, has reduced human factor (the turnover baking oven is overtime or when subtracting, the people is for bumping phenomenons such as curved), has saved labor hour.
4. because accomplish to pass in and out the first in first out of stove, and there is stationary temperature to do assurance, production assurance has been had strong assurance.
5. the raising, particularly high-temperature current leakage that have guaranteed conventional electrically consistency of product and high-temperature behavior obviously reduce before the change.
Description of drawings

Fig. 2 is the conveying vertical view of the utility model automatic conveying device.
Embodiment
The present invention specifically is made up of following steps:
A, filling: in Shi Muzhou, the row of lead-in wire is loaded layer weld tabs and crystal grain by routine backward, and then load onto a layer weld tabs and compress.
B, welding: the Shi Muzhou of the weld tabs that installs is sent to more than 300 ℃, is full of in the furnace chamber in the stove of nitrogen, and high-temperature baking is more than 12 minutes in this road, and the temperature peak in the assurance stove is come out of the stove after welding finishes at 360～370 ℃.
C, the diode semi-finished product after the above-mentioned welding are carried out pickling, sliver by routine.
D, preliminary drying: the initial temperature in the stove is controlled at 100 ℃, heats up then, at 203 ℃-216 ℃ product is carried out preliminary drying to peak temperature; During preliminary drying in the stove temperature be controlled at 30 minutes greater than time of 150 ℃; After preliminary drying finishes, temperature is controlled at 160～180 ℃ comes out of the stove, coming out of the stove is delivered to glue process through automatic conveying device.
Specify the control that product is come out of the stove below in conjunction with automatic conveying device, automatic conveying device is following: like Fig. 1, shown in 2, comprise frame 1, conveying 2, fixed axis 3, roller 4, cooling support 5, cooling fan 6.
Above-mentioned frame 1 is provided with the conveying 2 that a horizontal direction is extended, and between conveying 2, is provided with the fixed axis 3 that some equidistance are arranged, and is set with roller 4 or bearing on the every axle, and the rotating direction of roller 4 is identical with conveying 2 bearing of trends.
Directly over conveying 2, be provided with cooling support 5 in parallel, the cooling fan 6 that several aim at conveying 2 downwards is installed on cooling support 5.
During use; The outlet of the preceding termination soldering furnace of conveying 2; End connects the glue process corresponding apparatus, through soldering furnace pre-baked graphite boat 7 in the wings under the promotion of graphite boat successively along conveying 2 reaches, in the time of reach; Carry out air-cooledly through cooling fan 6 blowing, last graphite boat carries out photoresist coating process from the glue application device at conveying 2 entering rears.
E, gluing: gluing is carried out conventional gluing with the gluing speed of 50PCS/MIN under being 38～41 ℃ temperature in material temperature.
F, be that solidify conventional adhesive curing, compression molding, back at last, final finished product.Above step is conventional steps entirely, this no longer tired stating.
The diode of producing by above step because whole production line has realized automatic continuous productive process through automatic conveying device, and process conditions in some aspects improve, the product of gained have fabulous electrically.Can obtain reverse leakage current VR＜1 μ AVR=1000V, it leaks electricity far below standard VR＜5 μ AVR=1000V.
