As it is shown in figure 1, a kind of solder paste stirrer of the present invention, including base 1, base 1 being provided with support bar 2 and tin cream fixes cylinder 5, the rear end of lifting arm 3 is arranged on support bar 2, and lifting arm 3 can move up and down on support bar 2.Lifting arm 3 is arranged on support bar 2 by the various ways of prior art and is formed with support bar 2 and is slidably matched, as turbine and worm designs.Motor 4 is installed below the front end of lifting arm 3, control box 20 can be installed above the front end of lifting arm 3, control box 20 and be connected by electric wire with motor 4, realize the control to motor 4 by controlling box 20.Motor 4 is positioned at tin cream and fixes the surface of cylinder 5, and the output shaft of motor 4 is provided with stirring rod component 6.Tin cream fixes cylinder 5 for placing tin cream box body, and the most traditional tin cream box body is circular, is directly placed at tin cream and fixes in cylinder 5, then is stirred it by stirring rod component 6.
As in figure 2 it is shown, stirring rod component 6 includes the stirring rod fixing head 7 being arranged on motor 4 output shaft, upper hard stirring rod 8 and elastic stirring rod 9 are installed in stirring rod fixing head 7.The stirring of tin cream in tin cream box body of upper hard stirring rod 8, the elastic stirring rod 9 tin cream stirring at tin cream inboard wall of cartridge.Owing to tin cream box body is working of plastics, if using traditional hard stirring rod to be stirred, the inwall of the tin cream box body that do not simply fails to fit, and easily cause the Housing failure of tin cream box body, at this, special employing has resilient material and is stirred at tin cream inboard wall of cartridge.Therefore elastic stirring rod 9 can select the material into iron wire, copper wire or flexiplast.
Upper hard stirring rod 8 includes the cross bar 21 being arranged in stirring rod fixing head 7, and the two ends of cross bar 21 are provided with the perpendicular rod A22 and perpendicular rod B23 being perpendicular to cross bar 21, i.e. erects rod A22, cross bar 21 and perpendicular rod B23 three and combines in inverted " u " font.Equally, elastic stirring rod 9 includes the resilient cross-bar 24 being arranged in stirring rod fixing head 7, the two ends of resilient cross-bar 24 are provided with the elastic rod A25 and elastic rod B26 being perpendicular to resilient cross-bar 24, and elastic rod A25, resilient cross-bar 24 and elastic rod B26 three combine in inverted " u " font.Maximize to realize stirring scope, resilient cross-bar 24 and both cross bars 21 are arranged in " ten " font, and the length of resilient cross-bar 24 is more than cross bar 21, the length of resilient cross-bar 24 equals to or less than tin cream box body diameter, and resilient cross-bar 24 is stirred for tin cream at the inwall of tin cream box body.
In order to increase stirring scope further, simultaneously because upper hard stirring rod 8 and elastic stirring rod 9 are arranged in " ten " font, and the mixing effect of elastic stirring rod 9 is poorer than hard stirring rod, therefore connecting rod 32 can also be included, connecting rod 32 be used for adding load hard stirring mix rod 31, connecting rod 32 is vertically mounted on the lower section of cross bar 21.The lower section of connecting rod 32 is provided with lower hard stirring rod 31, and lower hard stirring rod 31 includes the sheer pole 33 being arranged on below connecting rod 32.In like manner, the two ends of sheer pole 33 are provided with the perpendicular rod C34 and perpendicular rod D35 being perpendicular to sheer pole 33, and perpendicular rod C34, sheer pole 33 and perpendicular rod D35 form inverted " u " font.The position of sheer pole 33 is corresponding with resilient cross-bar about 24, to make up the defect of the mixing effect difference of elastic stirring rod 9.Same in order to increase stirring scope, it is achieved the stirring to tin cream box body central spot, it is also possible to include that perpendicular rod E36, perpendicular rod E36 are arranged on the lower section of sheer pole 33 so that it is be stirred for tin cream box body central spot.Perpendicular rod E36 is " several " font, adds the range of disturbance of tin cream to the full extent.
Fix cylinder 5 due to tin cream and the installation of tin cream box cannot be ensured its stable effect, also there will be the situation that tin cream box rotates when stirring rod component 6 is stirred, cylinder 5 sidepiece can be fixed at tin cream and install clamp assembly 10 additional.As shown in Figure 3 and Figure 4, clamp assembly 10 includes screw rod fixed station 11, screw rod fixed station 11 is arranged on tin cream and fixes on the outer wall of cylinder 5, screw thread mouth 12 is had on screw rod fixed station 11, screw rod fixed station 11 and tin cream are fixed and be there is also a certain distance redundancy between the outer wall of cylinder 5, for installing outer catch 16 slot milling.Banking pin 15 is fixed from tin cream and is outwards sequentially passed through tin cream stay 13, fixing cylinder stay 14 and tin cream in cylinder 5 and fix the barrel of cylinder 5, i.e. tin cream stay 13, fixing cylinder stay 14 and be positioned at tin cream and fix cylinder 5, by banking pin 15 through fixing.The head of banking pin 15 is positioned at tin cream and fixes cylinder 5, and tin cream stay 13, fixing cylinder stay 14 are spacing in tin cream fixes cylinder 5 by the blunt portion (disk) of banking pin 15.The bottom of banking pin 15 is positioned at tin cream and fixes outside cylinder 5, i.e. cylinder 5 is fixed, outside tin cream fixes cylinder 5 through tin cream in the tip of banking pin 15.The quantity of banking pin 15 can be 2, the bottom limiting nail 15 is installed with outer catch 16, thus tin cream stay 13, fixing cylinder stay 14 and outer catch 16 are all run through fixing by restriction nail 15, but tin cream stay 13, fixing cylinder stay 14 are positioned at tin cream and fix cylinder 5, and outer catch 16 is positioned at tin cream to be fixed outside cylinder 5.Outer catch 16 is provided with through hole A17, tin cream is fixed the barrel of cylinder 5 and is provided with through hole B18, screw thread mouth 12, through hole A17 and through hole B18 three are located on the same line, and threaded rod 19 is arranged on the screw thread mouth 12 of screw rod fixed station 11 and sequentially passes through through hole A17 and through hole B18.
When at this, the purpose of design tin cream stay 13, fixing cylinder stay 14 and outer catch 16 is to prevent rotating threaded rod 19 from limiting tin cream box body, the most excessive, tin cream box body is racked.In order to form tin cream stay 13 effectively fixing tin cream box body, the move distance making tin cream stay 13 meets the fixing needs to tin cream box body, the length of banking pin 15 distance less than screw thread mouth 12 to through hole B18, and when tin cream box body be arranged on tin cream fix in cylinder 5 time, the length of banking pin 15 fixes the distance of cylinder 5 inwall more than tin cream box body outer wall to tin cream.When threaded rod 19 is when further rotating, the active force of its threaded rod 19 acts on fixing cylinder stay 14, i.e. presses tin cream box body at crowded tin cream stay 13, fixing cylinder stay 14.This uses the active force of an original point to become the active force in a face, and stressed effect is good, but single-point pressure-bearing is little.At the same time it can also be tin cream stay 13 and fixing cylinder stay 14 are arc, the radian of fixing cylinder stay 14, less than tin cream stay 13, so makes fixing cylinder stay 14 can produce certain elastic force for tin cream stay 13.Therefore, tin cream stay 13 and fixing cylinder stay 14 can select copper sheet.
When actually used, first tin cream box body is fixed.Tin cream box body is placed on tin cream fix in cylinder 5, screws threaded rod 19.The fixing cylinder stay 14 of threaded rod 19 extruding, fixing cylinder stay 14 moves to tin cream box body direction against tin cream stay 13 in the range of movement of banking pin 15, causes tin cream stay 13 to be pushed against by tin cream box body.When tin cream is fixed after cylinder 5 pushes against and put in place by tin cream stay 13, the power that rotating threaded rod 19 produces again, though acting on tin cream stay 13, but tin cream stay 13 is fixed on the outer catch 16 that tin cream is fixed outside cylinder 5 by banking pin 15 in conjunction with fixing cylinder stay 14, that is tin cream stay 13, fixing cylinder stay 14 can only move in the range of banking pin 15, its motion beyond the scope of banking pin 15, thus can not cause threaded rod 19 to rotate again.When the distance of rotating threaded rod 19 has reached tin cream stay 13, the fixing cylinder stay 14 range of movement limit on banking pin 15, even if stepping up rotating threaded rod 19 the most again, tin cream stay 13, fixing cylinder stay 14 simply can be made to produce deformation, and not producing chucking power again for tin cream box body, it is therefore prevented that the extruding of tin cream box body ruptures.After tin cream box body fixes, re-use lifting arm 3 to be moved down by stirring rod component 6, motor 4 works, the elastic stirring rod 9 of stirring rod component 6 is to carrying out Stirring at the inwall of tin cream box body, the upper hard stirring rod 8 of stirring rod component 6, lower hard stirring rod 31 and perpendicular rod E36 carry out uniform stirring to other positions of tin cream box body.
