The specific embodiment
Be elaborated below in conjunction with the technical scheme of accompanying drawing to invention:
Heat gun of the present invention comprises main body, controller, heater, fan, sensor, tuyere, square tube; Wherein said controller, heater, fan are positioned at main body, are used to form hot blast; Described controller is connected with heater, fan, sensor respectively.
Structured flowchart of the present invention as shown in Figure 1, described square tube is positioned at main center's shaft position, an end is connected with main body, the other end is connected with range sensor; Described tuyere is connected with square tube.Described tuyere lower end is four prisms cylinder, the upper end is the rectangular pyramid body, four of four prisms cylinder faces four faces of corresponding rectangular pyramid bodies respectively wherein, and four prisms cylinder and rectangular pyramid body connect by first active connection between corresponding two faces respectively, and the summit of four faces of described rectangular pyramid is passed through second active connection respectively and is connected with square tube; Each face of described four prisms cylinder and rectangular pyramid body comprises the n part respectively, and wherein n is the natural number greater than 1.Described tuyere comprises two, and wherein second tuyere is arranged on the first tuyere inside, and four face correspondences of two tuyere four prisms cylinder ends be arranged in parallel; Described first, second tuyere is connected with square tube by connector respectively.Described sensor comprises temperature sensor, range sensor, and described temperature sensor is for detection of the temperature signal of hot blast, and described range sensor is connected with square tube, for detection of the size for the treatment of Operand size of devices and welding foot.Tuyere four prisms cylinder part includes corresponding a plurality of parts with the rectangular pyramid body portion, connects by first active connection, makes things convenient for the change of tuyere size.
Described square tube adopts heat-barrier material, is used for connecting first, second tuyere, and the inner connecting line that is used for arranging between each parts prevents that connecting line is subjected to heat ageing or damage for a long time simultaneously.
Adopt two tuyeres, make hot blast blow to components and parts by two tuyeres are middle, and only heat the pin of components and parts, do not influence peripheral components and parts, avoid long-time heating to treat the Operand device outer case simultaneously, cause component aging or damage, prolong components and parts service time.
Second tuyere, one end adopts the rectangular pyramid structure, makes the air flow resistance of heating reduce, and more passes through two tuyere intermediate flows to components and parts to be heated.
When needs operation BGA encapsulation or the components and parts of welding pin below shell, need whole components and parts heating, but folk prescription is to mobile active connection, make that hot blast only needs simultaneously to blow out from hot blast nozzle, different mode of operations can be changed the relative position relation of first, second tuyere, convenient multiple application.
The present invention also comprises drive motors, is connected with described first, second active connection, is used for the action of control connection part.
The course of work of the present invention is as follows:
Range sensor detects size and the pad size of IC package casing, detected signal is sent to controller, controller is according to the signal that receives, judge the size of required tuyere, by control drive motors revolution control tuyere size, according to the difference that detects size and current tuyere size, required tuyere size is calculated the drive motors revolution, sets the drive motors revolution then, sends control signal, the control drive motors rotates, drive motors drives the active connection motion, when detected size greater than current tuyere size, controller is judged needs to strengthen the tuyere size, drive motors just changes, and drives the motion connector and shrinks; When detected size less than in current tuyere size, controller is judged need reduce the tuyere size, the drive motors counter-rotating drives connector and stretches; When drive motors arrives the revolution of setting, stop operating, tuyere reaches the required size of IC to be welded or dismounting.
When range sensor does not detect components and parts to be measured, controller sends standby signal, closes the work of heat gun, has reduced because not closing heat gun to operating personnel's injury, has saved electric energy.
Controller preestablishes heating-up temperature, starts heater, and temperature sensor detects Current Temperatures, when reaching predefined heating-up temperature, heater keeps steady temperature, starts fan, and tuyere air outlet guiding components and parts to be heated are crossed in the circulation of air after the heating.
