Abstract
The utility model discloses the welded joint structural improvement for a pulsation welding machine. A first welded joint is connected to a main machine, a second welded joint is inversely arranged below the main machine and faces to the first welded joint of the main machine, and the first and the second welded joints are connected to an output binding post of a transformer by a conducting wire. The technique can ensure that the double surface of a welded object can be synchronously heated, the loss heat amount is little, the welded object can be evenly heated, welding flux can be fully melted in approximate 250 DEG C., and an insulator of a coaxial line can not be damaged. The utility model can achieve a satisfactory welding effect.
Description
Technical field
The utility model relates to a kind of pulse machine plumb joint.
Background technology
Present disposing of pulse machine: one in transformer, one of control cabinet, one in main frame of welding, weld first.This bonding machine since only design a plumb joint is arranged, can only be used for single face contact welding.As it is blocked up to weld target, in the middle of the welding object continuous gap or other hot non-conductors is arranged, and then heat lose greatlyyer from contact-making surface to back side conductive process, guarantee enough heat melts scolders weld interval thereby need to improve welding temperature and extend.
At present notebook computer, LCD in the LCD TV, generally adopts a kind of 40amg to transmit signal to 32amg miniature diameter coaxial cable assembly.In this CA cable assembly,, generally clamp and be welded on the screen layer of the many coaxial cables of putting side by side with two thin scale coppers at the connector and the connector end that is connected display screen that connect mainboard.Technology is to adopt single cover pulse machine at present, pushes down the heating of single face copper bar with a soldering tip, and heat is transmitted on the scolder by the contact copper sheet, is transmitted on the screen layer of coaxial line again, is transmitted at last on the scolder and copper sheet at the back side.Thermal loss is very big in this course.According to international environmental requirement, in this product, must adopt lead-free solder.Welding temperature will be set in the abundant fusing that could guarantee scolder about 340 degrees centigrade.
The insulating barrier of coaxial cable is a Teflon, and fusing point is about 280 degrees centigrade, and is can Yin Wendu in existing single face contact heating welding procedure too high and scald the insulating barrier of cable, thereby causes phenomenons such as defective insulation or short circuit.
Fraction defective is more than 3.5% in the actual job.Therefore the scrappage that causes is more than 1.5%.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of pulse machine plumb joint structural improvement, this pulse machine makes with the plumb joint structural improvement that object is two-sided to be heated simultaneously, thermal loss is few, object is heated evenly, about 250 degrees centigrade,, do not damage the insulator of coaxial line, reach satisfied welding effect with regard to the abundant melting solder of energy.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of pulse machine plumb joint structural improvement, first plumb joint is connected on the main frame, second plumb joint is inverted under the main frame and first plumb joint on the main frame, and first and second plumb joint is linked on the output wiring terminal of transformer by lead.
First and second plumb joint is parallel on the output wiring terminal of transformer by lead.
The beneficial effects of the utility model are: because first plumb joint is connected on the main frame, second plumb joint is inverted under the main frame and first plumb joint on the main frame, and first and second plumb joint is parallel on the output wiring terminal of transformer by lead; Can guarantee like this that object is two-sided is heated simultaneously, and thermal loss is few, and object is heated evenly, and abundant melting solder just about 250 degrees centigrade does not damage the insulator of coaxial line, reaches satisfied welding effect.Whole world notebook computer, LCD, liquid crystal display television by using miniature diameter coaxial cable assembly comes from China more than 90%.
Domestic miniature diameter coaxial cable assembly shipment amount is as follows respectively:
Notebook computer consumption: 2,000 ten thousand/year
LCD consumption: 1,000 ten thousand/year
LCD TV consumption: 5,000,000/year
Unit price is respectively 4 dollars, and 2 dollars, 4 dollars
The present invention can reduce by 1.5% scrap, and can save ten thousand dollars of 2000*1.5%*4+1000*1.5%*2+500*1.5%*4=180; Be that this utility model benefit can reach 1,800,000 dollars every year.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is a schematic diagram of the present utility model;
The specific embodiment
Embodiment: referring to Fig. 1, a kind of pulse machine plumb joint structural improvement, first plumb joint 1 is connected on the main frame 2, and second plumb joint 3 is inverted in main frame 2 times and first plumb joint 1 on the main frame 2, and first and second plumb joint is linked on the output wiring terminal of transformer 4 by lead.
First and second plumb joint is parallel to by lead on the output wiring terminal of transformer, can guarantee the heat unanimity that first and second plumb joint produces like this.
Operation principle of the present utility model and use are:
This case is heated evenly the welding thing to the two-sided heating simultaneously of welding object, makes scolder in lower temperature and fully fusing in the short period, makes the weld scolder full, firm welding.
Connect power supply, on control cabinet, configure the required temperature and time of welding.On the welding object, add scolder, the welding object is placed on second plumb joint, touch and open switch by fixed jig, first plumb joint is depressed, and the welding object is pressed on second plumb joint, when setting-up time and temperature arrival, first and second plumb joint unclamps automatically, and welding is finished.
In this example, available two transformers and even a plurality of, first and second plumb joint connects a transformer respectively, belongs to the no creationary replacement that is equal to, and is similarly this routine claimed scope.
