Description
Technical field
What the present invention relates to is a kind of device of electronic technology field, specifically is a kind of plumb joint that is used for the radio frequency recognizing electronic label packaging line.
Background technology
Automatic identification technology commonly used in industrial and agricultural production and the daily life mainly comprises shooting (image recognition), bar code, magnetic card, IC-card, REID etc., and wherein, REID has obtained extensive use in recent years.The composition of RF identification (RFID) system generally comprises two parts at least: electronic tag, reader.At present, minority foreign corporation has the manufacturing technology of electronic tag, the domestic electronic tag packaging production line that does not still have independent intellectual property right.The complete electronic tag packaging line of one cover should comprise following main function: modules such as loading and unloading, some glue, pre-binding, whole binding and detection, for realizing this energy altogether, the requirement of butt joint has: 1) can guarantee high-precision constant temperature welding temperature; 2) can apply constant welding pressure to chip; 3) can strict antistatic; 4) owing to have several plumb joints to work simultaneously on the streamline, therefore require single plumb joint power consumption less; 5) for realizing the processing flexibility of streamline, require and can select dress by butt joint, therefore need the plumb joint volume less according to processing technology, and easy accessibility; 6) the non-heating part of plumb joint needs heat dispersion preferably, influences the operate as normal of surrounding devices to prevent it.
At present, this class welder does not have fixing version, and different packaging production lines design separately according to technological requirement.Common design guidance scheme has two kinds, and a kind of scheme utilizes ultrasonic generator that the scolder fusion between chip and the substrate is welded, and this method cost is lower, the efficient height, but realize that difficulty is higher, and versatility is relatively poor; Another kind of scheme directly utilizes heater to push chip, makes chip be connected with substrate.
Find through literature search prior art, be published in electronic building brick in 2000 and technology international conference opinion (" Electronic Components and Technology Conference; 2000.2000Proceedings.50th; the article classification number is: document 6721863) " the submicron upside-down mounting binding technology that is used for photoelectron device " (Submicron Flip Chip Bonding Technology ForOpto-electronic Devices); proposed a kind of typical design in this article; this scheme adopts electrical heating head that chip is heated, and by the air slide device non-heater block is cooled off again.But should design need to eliminate heating head static, and the heat abstractor overall dimensions is bigger, makes this plumb joint only be fit to the single-piece operation.And in order to enhance productivity, the RFID packaging production line requires the dozens of plumb joint to work simultaneously, and therefore, this scheme can't be used for the encapsulation of RFID chip.
Summary of the invention
The present invention is directed to above shortcomings in the prior art, a kind of plumb joint that is used for the radio frequency recognizing electronic label packaging line is provided, make it be used for radio frequency recognizing electronic label packaging production line binding unit eventually, make it heat pressurization, realize the welding between chip and the radio-frequency antenna electronic label chip.The present invention can guarantee high-precision constant temperature welding temperature, can apply constant welding pressure to chip, the strict antistatic of energy, and single plumb joint power consumption is less, and volume is less, and easy accessibility, and non-heating part has heat dispersion preferably.
The present invention is achieved by the following technical solutions, the present invention includes: heating head, radiator, cylinder piston connector, gas path joint, tracheae, cylinder, base, permanent magnetic iron.Adopt bolt to be connected between heating head and the radiator, and, carry out heat insulation with mica spacer between the two; Heat insulation between radiator and the cylinder piston connector with mica spacer, connect by bolt; The cylinder piston joint element for bar is designed to the structure of hollow, connects two tracheaes by gas path joint, and two tracheaes are bled respectively and blown to realize the purpose of heat exchange; The base of the square hollow of cylinder tip designs, the inner permanent magnetic iron of installing of base is fixed by the mode and the irony installed surface of adhesive, and is guaranteed its mounting stability by marking closely screw.
Heating head is made by ceramic material, and inside is provided with cylindrical PCT thermostatic element, and thermostatic element two bottom surfaces are provided with flake aluminum.During installation, the heating head inner bottom surface is close in a bottom surface of thermostatic element, fills gap thermostable heat-conductive material between thermostatic element and the heating head inner chamber, fills with high-temperature resistant thermal insulating material on another bottom surface of thermostatic element.
Compared with prior art, beneficial effect of the present invention is as follows: the 1) heating head made of ceramic material, and the structure of this heating head designs according to heat transfer principle, and having following advantage: a can strict antistatic; Temperature stabilization during the b heating; C ceramic material wearability is better, can obviously improve the service life of product, and guarantees repeatedly to use still have degree of precision; The d low cost of manufacture.2) use the PTC thermistor to carry out and to heat as thermal source, radio electronic label manufacture process requirement plumb joint provides constant welding temperature, and the PTC thermistor has constant temperature heating, the flames of anger, thermal conversion rate height, is subjected to supply voltage to influence advantages such as minimum, that natural life-span is long.3) radiator adopts heat conductivility preferred metal material to make, be designed to porous shape structure to increase area of dissipation, simultaneously, connect ventilation equipment by two pores on the piston rod connector, a pore is taken out area of dissipation, simultaneously, connect ventilation equipment by two pores on the piston rod connector, a pore is bled, and a pore is blown, to realize the purpose of quick heat radiating.4) cylinder plays the effect that guarantees welding pressure.The present invention drives heating head with cylinder and contacts with soldered chip, pressure when controlling welding by the air pressure in the control cylinder, the power control accuracy of this mode and flexibility are apparently higher than adopting spring controlled mode, and cost is lower, realizes that difficulty is also far below relying on motion control to guarantee the design of weld force.5) the cylinder tip designs irony base of magnetic, plumb joint is installed on the optional position of irony installed surface easily, and reinforces by marking closely screw, such design can make plumb joint dismantle at any time, and is easy to use.
