Abstract
The invention discloses a kind of rotary small-sized automatic immersed solder machine.It is to adopt a motor to drive two worm gear cases that gearratio is identical, the cam of the same specification of two opposite phases of transmission, the four station cross pivoted arm immersed solder framves that link rotation and rightabout vertical synchronization campaign about little tin pot is done are to finish the immersed solder action automatically.It is the desirable small-sized automatic immersed solder equipment on the electronic product production line.
Description
The present invention is a kind of automatic rotary dip-soldering machine, is applicable to multi pack electronic devices and components on the electronic product flow production line, is particularly useful for the wicking welding of transformer and so on many pins device.
The automatic tin soldering bonding machine of using on the existing electronic product flow production line, its structure is complicated usually, and volume is big, cost is high, not easy-maintaining and use, so adapt to users' needs not to the utmost.For example vapour-pressure type immersed solder machine, injecting type bonding machine.
In order to overcome the above-mentioned shortcoming of prior art, purpose of the present invention, provide a kind of small portable, low-cost, the automatic immersed solder machine of rotary four stations that applicability is big, its component part comprises a body, the control cabinet of one stepless speed regulation circuit device is housed in one, one by a motor, driving-belt, main worm gear case, the main drive that cam and pivoted arm wheel constitute, a cross pivoted arm frame that moves with the timing rotation and the vertical up and down immersed solder of do of above-mentioned main drive interlock, transmission device of forming by driven worm gear case and worm-wheel shaft overhead cam thereof by the interlock of driving-belt and main worm gear case, do and the move up and down transmission device of the opposite synchronous vertically-acting up and down of direction of cross pivoted arm frame with the tin pot that makes that above-mentioned inverted cam links for one, one by a big tin pot, a little tin pot that its position is adjustable and an electric furnace form in solder bath and a scraping plate of automatic device of scraping the black layer of scolding tin solution surface oxidation in the detin pot automatically of scolding tin solution are housed, automatic immersed solder agent and device for discharging.
The present invention is under stepless speed regulation circuit control, make rotatablely moving as the motor in machine power source, pass to two worm gear cases that gearratio is identical simultaneously by driving-belt, make it operation, two worm-wheel shafts of cam that the same specification of an opposite phase (differing 180 °) respectively is housed above the drive are done the constant speed rotation, wherein worm gear main shaft that a coupling device is housed drives the driven shaft that the upper end that is coupled with it is fixed with a cross pivoted arm frame and does regularly interrupted (90 ° of regularly stalls of revolution) clockwise rotation continuously, during this rotation (90 °), screeding device is finished the action of removing the black layer of scolding tin solution surface oxidation in the tin pot.When one 90 ° of pivoted arm frame rotations, when putting stall in place, its decoupling mechanism (pivoted arm wheel) above cam main shaft and the former driven shaft decoupling (closing) that is coupled and rotates, cross pivoted arm frame stops operating, meanwhile, roller by the driven shaft lower end closely contacts with cam working face, along with cam rotates a week, force the driven shaft of band cross pivoted arm frame to do once to move both vertically up and down, simultaneously, cam working face in another worm gear case on the worm gear main shaft also closely contacts mutually with the roller of little tin pot lowering or hoisting gear main shaft lower end, along with this cam rotates a circle, its lowering or hoisting gear is moved both vertically up and down, thereby the little tin pot that links move up and down.Because the vertically-acting up and down of little tin pot and cross pivoted arm frame is two opposite phase cam drives that are subjected to same motor, same gearratio worm gear case and same specification, so its action is synchronous, its direction is opposite (differing 180 °).
The length at immersed solder position can be finished by the adjustment of little tin pot position adjusting mechanism.
The present invention finishes the action of taking off workpiece for finish automatic immersed solder agent operation and immersed solder before automatic immersed solder after, the space below cross pivoted arm frame one symmetric arms front end is respectively equipped with a solder dipping machine and a shedding mechanism.
The present invention is attractive in appearance and immersed solder quality in order to ensure immersed solder position gloss, space below cross pivoted arm frame, be parallel to little tin pot scolding tin solution surface, a scraping plate of automatic device is housed, this device can carry out deoxidation layer casting skin one time to scolding tin solution surface in the little tin pot in cross pivoted arm frame immersed solder mechanism finishes four immersed solder processes.Designed according to this invention automatically the immersed solder machine volume is little, in light weight except that having, simple structure with cost low, it can be effectively than workman's immersed solder raise the efficiency 3-4 times, working stability reliably, immersed solder position neat and consistent, gloss.It is a desirable small-sized automatic immersed solder machine during electronic product is made.
