Utility model content
The utility model, which mainly solves the existing big welding quality of microminiaturized product lead welding difficulty, can not be guaranteed and weld
Connect the low technical problem of efficiency；The pre- hot charging of Product jointing for providing a kind of energy fast lifting preheating temperature and being easy to lead to weld
Put.
In order to solve above-mentioned technical problem, the utility model mainly uses following technical proposals：
A kind of Product jointing preheating device of the present utility model, the external lead wire for microminiaturized product weld, described device
Including base and the lower platen that is fixedly arranged on base, the lower platen is provided with column, is arranged with the column and lower platen
The top board for matching and being moved along column, formed between top board and lower platen and house and clamp the sky of the microminiaturized product
Between, the lower platen inner face is installed with the heater to be matched with microminiaturized product, and microminiaturized product is positioned over the top board with
Between pressing plate, its bottom surface fitting heater hot face, its top surface reclines top board inner face, and device in adjustable distance by pushing
Space between plate houses and clamped microminiaturized product, exposes the lead solder-joint of microminiaturized product, is easy to carry out under the microscope
Weld job, and microminiaturized product is directly placed at heater surfaces so that the welding region of microminiaturized product can reach required weldering
Connect preheating temperature, while the hot face size of heater is small, hand is not easy to encounter and scald during operation, the security of welding also compared with
It is high.
Preferably, the lower platen is oblique, pushing plate surface and susceptor surface has angle α, inclined to push
Plate can be such that the lead solder-joint of microminiaturized product exposes after clamping in oblique top, be easy to observe welding process under the microscope.
Preferably, described device also includes clamping plate and cam spanner, the clamping plate is located on the inside of the top board and covered
Loaded on the column, the cam spanner is fixedly arranged on top board, the cam leading section of cam spanner against and promote clamping plate
Moved axially along column, pull cam spanner, promote clamping plate to push and compress microminiaturized product, holding microminiaturized product is in welding
Clamped condition, without departing from or it is mobile, ensure the welding quality of microminiaturized product.
Preferably, being additionally provided with the fastening bolt for being fixed with the column on the upper vertical plate, fastening bolt will be upper
Pressing plate is fixed on column, and the distance in welding in guarantee between lower platen will not be offset.
Preferably, being provided with the temperature sensor of control heater hot-face temperature in the heater, outside control is external to
The temperature sensor of circuit processed can combine temperature lift-down curve and accurate temperature controlling is carried out to heater, conveniently preheating during welding.
The beneficial effects of the utility model are：Space between the upper lower platen that device passes through adjustable distance come it is accommodating simultaneously
Microminiaturized product is clamped, exposes the lead solder-joint of microminiaturized product, is easy to carry out weld job under the microscope, and microminiaturized product leads to
The effect for crossing cam spanner directly rides over heater surfaces so that the welding region of microminiaturized product can be rapidly achieved required weldering
Connect preheating temperature, improve welding quality, while the hot face size of heater is small, the scald of hand, welding will not be caused during operation
Security is higher.
