Diode sizer
Technical field
The present invention relates to diode and manufacture field, be specifically related to a kind of diode sizer.
Background technology
Diode is in the middle of electronic component, a kind of device with two electrodes, only allows electric current to be flow through by single direction.The most general function of diode is exactly only allow an electric current by single direction by (being called forward bias voltage drop), blocks (being called reverse bias) time reverse.Therefore, diode can be thought of as the non-return valve of electronic edition.
In the production technology of existing axial diode, its technological process is: lead is to-cDNA microarray-chip filling-welding, and----------plastic packaging-----------examine outward--and pack Post RDBMS in plating by lettering test in baking in gluing in pickling.Wherein going up glue process refers to after pickling, and the die surfaces through hyperthermia drying moisture is coated with one deck silicon rubber makes tube core P-N junction and external environment keep apart, and to avoid surrounding impurities on the impact of device performance, can play protection tube core, stablize die surfaces.Diode gluing mode of the prior art is by diode arrangement in upper adhesive tape, by manually carrying out gluing one by one to diode, after gluing, diode being delivered to oven dry place and carrying out glue curing.Its defect is: gluing efficiency is low, can not carry out batch gluing to diode, and labor strength is large, easily produces the underproof diode of gluing.
Summary of the invention
The invention is intended to provide a kind of diode sizer, to facilitate, batch gluing is carried out to diode, improve gluing efficiency, reduce labour intensity.
For achieving the above object, basic technology scheme of the present invention is as follows: diode sizer, comprises base, control unit and glue injection units.Described base is rectangular box, and described control unit is positioned at the inside of base, and the front side of base is provided with the control board be electrically connected with control unit.Described base is fixed with the bracing frame of " door " shape, the upper end of base is provided with longitudinal slide rail, and slide rail slidably connects holder, and described slide rail and fixed seating are in the below of bracing frame.Described glue injection units is slidably connected at the top of bracing frame, described glue injection units comprises the slide that can slide on bracing frame, the inside of described slide is provided with the vertical cylinder installed, the bottom of slide is provided with packing element and presss from both sides for embracing of fixing packing element, and the output of described cylinder is connected with the top of packing element.
Principle and the advantage of this programme are: during operation, after arranging, are fixed on needing the diode of gluing on holder by graphite boat on graphite boat.Make holder drive graphite boat vertically moving by control board and control unit, make slide transverse shifting on bracing frame, by the position adjustment of vertical and horizontal, the glue discharging mouth of packing element is alignd with the gluing point of diode on graphite boat like this.Cylinder drives packing element in vertical movement, glue is dripped on the diode from the glue discharging mouth of packing element, completes the gluing of diode.Movement that is longitudinal, horizontal and vertical three directions can be realized by arranging slide rail, bracing frame and cylinder, feeding control is carried out by control unit, compared to traditional mode of production by manually carrying out gluing one by one to diode, operate simpler, reduce labor strength, improve gluing efficiency, more convenient to batch the diode be arranged on upper sealing rubber die accurately locate gluing, can complete fast and the gluing of batch diode is operated.
Preferred version one, based on scheme one improve, described holder is the aluminium sheet of rectangle.The holder light quality of aluminum, with low cost, there is alumina layer on surface, and glue is not easily bonded on holder, easy cleaning.
Preferred version two, preferably the one of is improved, and one-body molded on holder have four reference columns, and described four reference columns are in the rectangular distribution in the upper end of holder.Be arranged through reference column like this to position upper sealing rubber die, on when avoiding holder to move on slide rail, sealing rubber die generation skew causes to carry out accurate gluing to diode.
Preferred version three, preferably two one improve, the sidewall of support frame as described above upper end is provided with illuminating lamp, described illuminating lamp by connection by metal hose on bracing frame.Arrange illuminating lamp conveniently to observe in time diode gluing situation, metal hose enables illuminating lamp throw light on from each angle, and making does not have dead angle during observation, makes monitoring in time more comprehensive.

Embodiment
Below by embodiment, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: base 1, bracing frame 2, slide rail 3, slide 4, packing element 5, reference column 6, electricity-saving lamp 7, control board 8, holder 9.
Embodiment is substantially as shown in Figure 1: diode sizer, comprises base 1, control unit and glue injection units.Described base 1 is rectangular box, and described control unit is positioned at the inside of base 1, and the front side of base 1 is provided with the control board 8 be electrically connected with control unit.Described base 1 is fixed with the bracing frame 2 of " door " shape, the upper end of base 1 is provided with longitudinal slide rail 3, slide rail 3 slidably connects holder 9, and described slide rail 3 and holder 9 are positioned at the below of bracing frame 2.Described holder 9 is the aluminium sheet of rectangle, and one-body molded on holder 9 have four reference columns 6, the described rectangular upper end being distributed in holder 9 of four reference columns 6.Described glue injection units is slidably connected at the top of bracing frame 2, described glue injection units comprises the slide 4 that can slide on bracing frame 2, the inside of described slide 4 is provided with the vertical cylinder installed, the bottom of slide 4 is provided with packing element 5 and presss from both sides for embracing of fixing packing element 5, and the output of described cylinder is connected with the top of packing element 5.The top of slide 4 is provided with the flat cable be connected with bracing frame 2 top, and the sidewall of support frame as described above 2 upper end is provided with electricity-saving lamp 7, described electricity-saving lamp 7 by connection by metal hose on bracing frame 2.
In the present embodiment, during operation, after arranging needing the diode of gluing on graphite boat, graphite boat is fixed on holder 9.Make holder 9 drive graphite boat vertically moving by control board 8 and control unit, make slide 4 transverse shifting on bracing frame 2, by the position adjustment of vertical and horizontal, the glue discharging mouth of packing element 5 is alignd with the gluing point of diode on graphite boat like this.Cylinder drives packing element 5 in vertical movement, glue is dripped on the diode from the glue discharging mouth of packing element 5, completes the gluing of diode.Holder 9 light quality of aluminum, with low cost, there is alumina layer on surface, and glue is not easily bonded on holder 9, easy cleaning.Positioned upper sealing rubber die by reference column 6, on when avoiding holder 9 to move on slide rail 3, sealing rubber die generation skew causes to carry out accurate gluing to diode.Arrange electricity-saving lamp 7 conveniently to observe in time diode gluing situation, metal hose makes electricity-saving lamp 7 can throw light on from each angle, makes do not have dead angle during observation, makes monitoring in time more comprehensive.Movement that is longitudinal, horizontal and vertical three directions can be realized by arranging slide rail 3, bracing frame 2 and cylinder, feeding control is carried out by control unit, compared to traditional mode of production by manually carrying out gluing one by one to diode, operate simpler, reduce labor strength, improve gluing efficiency, more convenient to batch the diode be arranged on upper sealing rubber die accurately locate gluing, can complete fast and the gluing of batch diode is operated.
