Component 3 uses infrared heating device, and the two forms the infrared preheating zone to wiring board.
In conjunction with shown in Figure 10, the lower zone in the bottom of mainframe 1, PCBA fixed jigs 2 is provided with guide y
The y of rail sliding assembly 14 and the is provided with jet flow to servo-drive component 141 on a y direction guiding rails sliding assembly 14
Tin furnace module 5, the jet flow tin furnace module 5 includes tin furnace cradle 51, lifting table plate 52, tin furnace device 53, wherein, tin furnace cradle
51 is cuboid framework, and a pair of surface middle parts in its four side are separately installed with a longitudinal screw mandrel 511, another to surface middle part
Der Laengslenker 512 is respectively mounted, two longitudinal screw mandrels, 511, two Der Laengslenkers 512 are respectively by longitudinal nut seat 513, longitudinal direction
Guide rod bearing block 514 is connected with the corner of lifting table plate described in one 52；The bottom of the longitudinal screw mandrel 511 is provided with synchronizing wheel
515, lifting motor 54 is additionally provided with the side of tin furnace cradle 51, the output end of lifting motor 54 passes through synchronous pulley driving mechanism
541 are connected with the synchronizing wheel of the bottom of longitudinal screw mandrel 511；
Worked by lifting motor 54 and rotated, make two longitudinal screw mandrels 511 synchronous by synchronous pulley driving mechanism 541
Rotation, and then lifting table plate 52 is produced elevating movement by longitudinal nut seat 513, so that the tin stove dress on lifting table plate 52
Put 53 common liftings；Der Laengslenker 512 plays a part of to share support and stabilization lifting；Again by a y to servo-drive group
Part 141 drives whole jet flow tin furnace device 5 to move along the y-axis direction, and the x with PCBA fixed jigs 2 is engaged to movement, realizes
PCBA comprehensive movements in the horizontal plane, so as to be positioned to carry out sealing-off, change the position of part；Jet flow tin furnace device 5 itself can
With along its tin furnace cradle 51 in z to elevating movement, so as to the jet nozzle for realizing tin furnace device 53 is relative with PCBA welding positions
Motion；
In conjunction with shown in Figure 11, Figure 12, the upper area at the top of the mainframe 1, PCBA fixed jigs 2 is provided with
Robot device 6, the robot device 6 includes the 2nd y direction guiding rails sliding assembly 15 and the 2nd y installed in the top of mainframe 1
To servo-drive component 151, the z on the 2nd y direction guiding rails sliding assembly 15 to installing plate 61, installation z to installing plate 61
On a z direction guiding rails sliding assembly 611 and the z that is attached thereto to servo-drive component 612, installed in guide z
Electric rotating machine 62 and reduction box 63 and reduction box 63 on rail sliding assembly 611 output end connection z to air cylinder support 64,
Installed in z to the z in air cylinder support 64 to cylinder 641 and installed in clamping jaw supporting plate 65 from z to the both sides of air cylinder support 64,
The clip claw mechanism 66 being connected to cylinder 641 on the inside of clamping jaw supporting plate 64 and with z；2nd y drives to servo-drive component 151
The slide of dynamic 2nd y direction guiding rails sliding assembly 15 is along y to moving；Z controls the release of clip claw mechanism 66 and clamps to cylinder 641,
Electric rotating machine 62 and reduction box 63 control whole z to cylinder 641 and its z to air cylinder support 64 and whole clip claw mechanism 66 rotation
And angle, so as to turn to the angle of most suitable clamping according to the angles and positions of plug connector on PCBA, it is ensured that pull out the accurate of part
And stabilization.
Furthermore, also it is separately installed with a hot blast in the outside of two clamping jaw supporting plates 65 of the robot device 6
Pipe 67, the air outlet of warm-air pipe 67 is towards the bottom of clip claw mechanism 66.Wiring board upper surface is entered by the warm-air pipe 67 of both sides
Row auxiliary heating, thermal compensation is carried out to wiring board in sealing-off as needed, prevent because heat scatter and disappear it is too fast and caused by tin melt
Do not cause thoroughly to pull out part difficulty, suitable circuit plate thickness is larger, welding hole relatively carries radiating module etc. deeply and on electronic device
The occasion of sealing-off operation is carried out during structure；For normal or relatively thin PCBA, heat and can subtract by the auxiliary of warm-air pipe 67
Few wicking time, it is to avoid because melting the phenomenons such as copper caused by wicking overlong time, so as to further lift repair welding quality.
In above-mentioned automatic repairing machine：The z of robot device 6 is also associated with vibration motor 642 to the back side of air cylinder support 64, leads to
Crossing the work of vibration motor 642 can produce vibrations, the clip claw mechanism 66 of air cylinder support 64 and its underpart is produced vibrations, its effect
It is that after wiring board wicking removes tin, clip claw mechanism 66 is clamped when device is taken, and the vibrations produced using vibration motor 642 are applied to
Device, makes device be easier to separate with wiring board, and can be played a protective role to wiring board and device, it is to avoid strong to pull out
The wiring board that part is caused is damaged.
In conjunction with shown in Figure 11-Figure 14, in above-mentioned automatic repairing machine：The clip claw mechanism 66 of robot device 6 include with z to
First transverse axis 661 of the output end connection of cylinder 641, the two ends of the first transverse axis 661 are vertically located on clamping jaw supporting plate 65
In bar hole 651, bar hole 651 provides activity space and spacing first transverse axis 661 for the lifting of the first transverse axis 661；In two pieces of folders
Between pawl supporting plate 65, the lower section both sides of the first transverse axis 661 further respectively have the second transverse axis 662 parallel with it, each second
The two ends of transverse axis 662 are articulated with a pair relative to the movable jaw 663 that the first transverse axis 661 is arranged symmetrically, same second respectively
