Description
Technical field
The utility model relates to production of electronic components equipment, particularly the adjustable for height tin cream applying device of one.
Background technology
At surface mounting technology (the Surface Mount Technology of 20 century 70s, be called for short SMT), refer to printing on printed circuit board pad, coating tin cream, and Surface Mount Component is placed with accurately scribbles on the pad of tin cream, according to specific reflux temperature curve heater circuit plate, allow tin cream melt, between components and parts with printed circuit board, form solder joint after its alloying component cooled and solidified and realize the metallurgical technology be connected.
Tin cream is a kind of Novel welding material arisen at the historic moment along with SMT.Tin cream is by the lotion of solder powder, scaling powder and other additives mixed.Tin cream has certain viscosity at normal temperatures, can be bonded at commitment positions by the beginning of electronic devices and components, under welding temperature, along with the volatilization of solvent and portions additive, welded components and parts is formed permanent connection together with printed circuit pad solder.
Circuit board is the carrier of electronic devices and components, and electronic devices and components, by surface mounting technology or jack technology, are then firmly connected with circuit board by the technique of reflow soldering.What smear tin cream employing at present is manual method, is spread upon on alloy or other material surface by craft brush by tin cream, this method inefficiency.
Utility model content
In order to overcome above-mentioned defect, the utility model provides a kind of tin cream coating device, can by tin cream uniform application on a printed circuit board.
The utility model is achieved through the following technical solutions:
Adjustable for height tin cream applying device, comprise workbench, described workbench is provided with the bearing stage of level, the workbench of bearing stage relative to both sides is provided with parallel track, the portal trestle of back and forth movement is provided with above bearing stage, the two ends foot of described portal trestle and track are slidably matched, portal trestle is driven by driving mechanism, elastic scraper is provided with in portal trestle, the length of described scraper is greater than the width of bearing stage, the both sides of described portal trestle are provided with vertical bolt hole, and scraper two ends are fixedly connected with portal trestle through after bolt hole.
There is the angle between 30 ° ~ 90 ° on described scraper and bearing stage surface.
Described scraper material is metal or plastic-steel.
Described driving mechanism is be located at stepper motor above workbench and the chain horizontally rotated driven by stepper motors, and described portal trestle top is fixedly connected with chain bottom surface by connector.
The beneficial effects of the utility model are, employing the technical solution of the utility model can fast by tin cream uniform application on a printed circuit board, and replace artificial, apply effective, operating efficiency is high.And the utility model can regulate the height of hobboing cutter according to the circuit board of different-thickness, make hobboing cutter lower surface effectively can be fitted in the surface that circuit board need apply tin cream.
Accompanying drawing explanation

Detailed description of the invention
As shown in Figure 1, the utility model comprises workbench 1, and described workbench 1 is provided with the bearing stage 2 of level.Bearing stage 2 need apply the printed circuit board of tin cream for placing.
Above bearing stage 2, be provided with the portal trestle 4 of back and forth movement, as shown in Figure 3, the workbench 1 of the relative both sides of bearing stage 2 is provided with parallel track 3, and two ends foot and the track 3 of portal trestle 4 are slidably matched.
Still as shown in Figure 1, be provided with elastic scraper 5 in portal trestle 4, in order to obtain better elasticity and toughness, scraper 5 material can select metal or plastic-steel, such as iron, alloy plastic-steel etc. material.The length of described scraper 5 is greater than the width of bearing stage 2.
The both sides of portal trestle 4 are provided with vertical bolt hole 11, and scraper 5 two ends are fixedly connected with portal trestle 4 through after bolt hole 11.The two ends of scraper 5 can arrange screw thread, are then fixed by nut.
There is the angle between 30 ° ~ 90 ° on the surface of scraper 5 and bearing stage 2.If pliability is good, the angle (namely scraper 5 is perpendicular to bearing stage 2 upper surface) of 90 ° more can adapt to scraper 5 and come and go the printed circuit board surface blade coating tin cream back and forth on bearing stage 2, tin cream coating is needed on a printed circuit board in the solder joint groove of welding.
Composition graphs 1, Fig. 2 and Fig. 3, portal trestle 4 is driven by driving mechanism, in the present embodiment, driving mechanism is the stepper motor 6 be located at above workbench 1 and the chain 7 horizontally rotated driven by stepper motor 6, and described portal trestle 4 top is fixedly connected with by the bottom surface of connector 8 with chain 7.Sprocket wheel 9 identical sized by the two ends of chain 7, sprocket wheel 9 is fixed on the roller bearing 10 of level, and stepper motor 7 and one of them sprocket wheel 9 are in transmission connection, and drives chain 7 to move.Because the bottom of chain 7 is fixedly connected with by connector 8 with portal trestle 4, therefore stepper motor 6 drives chain 7 rotating, achieves the back and forth movement of portal trestle 4.
