Description
Technical field
The utility model belongs to field of semiconductor manufacture, particularly the utility appliance of diode chip pickling process, the i.e. tank level control system of acid solution on the diode production line.
Background technology
Diode chip must carry out fountain with acid solution and clean before welding, gluing and encapsulation, cleaning quality has influence on later process and diode end product quality; Acid solution is the strong liquid of corrosivity, easily form acid mist, to equipment, environment and human body harmful, therefore must place in the airtight container, the liquid that must keep constant level in the level tank makes follow-up spray equipment continuously, equably the diode chip on the automatic assembly line is carried out spray Cleaning for High Capacity.The diode pickler of a few days ago supplying on the market is and adds acid manually, adds the disadvantage of acid manually: the one, need to be equipped with the labour, and monitor the acid solution liquid level in the level tank at any time; The 2nd because acid solution is enclosed in the airtight container, artificial look-out difficulty, it is inhomogeneous therefore to add acid manually, difficulty or ease make the acid solution in the level tank keep constant liquid level position, often occur because of liquid level height, acid amount in the level tank too much, spray equipment sprays more; Or liquid level is low, acid solution is very few, the phenomenon that spray equipment sprays less, if the acid solution consumption is then wasted in many sprays, then diode chip is cleaning dirty if spray less.
Summary of the invention
It is a kind of simple in structure, reliable that the purpose of this utility model is to provide, and can control liquid level in the level tank automatically, both saved the cleaning fluid consumption, can guarantee that again diode chip can be cleaned clean tank level control system.
In order to achieve the above object, the technical solution of the utility model is: a kind of tank level control system, comprise liquid reserve tank, total valve, manual liquid feeding valve, level tank and pipeline, filling opening is arranged at liquid reserve tank top, liquid outlet is arranged at the liquid reserve tank bottom, inlet and liquid outlet are arranged at the level tank bottom, it is characterized in that: also comprise the unidirectional electrical magnet valve, float-ball type liquid level meter and three spacing photoelectric sensors, the liquid outlet of liquid reserve tank bottom is connected with total valve one end through pipeline, the other end of total valve is connected with an end of manual liquid feeding valve and the inlet of unidirectional electrical magnet valve respectively through pipeline, and manually the other end of liquid feeding valve and the liquid outlet of unidirectional electrical magnet valve are connected through the inlet of pipeline with the level tank bottom; The ball float of float-ball type liquid level meter floats on the interior liquid level of level tank, the induction column of float-ball type liquid level meter passes through the top cover of level tank and the top cover top that the induced indicia on the induction column is exposed to level tank, the top cover of level tank also is fixed with the sensor erection column outward, and three spacing photoelectric sensors are fixed on the sensor erection column compartment of terrain successively along the short transverse of liquid level.
Described three spacing photoelectric sensors are respectively lower limit photoelectric sensor, liquid feeding start bit photoelectric sensor and liquid feeding position of rest photoelectric sensor.
Described liquid reserve tank is positioned at the top of level tank.
The utlity model has following advantage; The utility model is by the unidirectional electrical magnet valve, float-ball type liquid level meter and spacing photoelectric sensor, can be when liquid level be lower than the lower limit liquid level, open the unidirectional electrical magnet valve, level tank is carried out liquid feeding, when liquid level in the level tank is higher than the upper limit liquid level, close the unidirectional electrical magnet valve, stop level tank being carried out liquid feeding, when liquid level in the level tank is lower than acoustic control lower limit liquid level, then remind the operative employee, carry out manual intervention, thereby keep the interior liquid level of level tank constant, reduce the fluctuation of spray equipment cleaning liquid inside operational throughput, this system architecture is simple, reliable, can save the acid solution consumption when being used for the diode chip descaling bath, can guarantee the diode chip cleaning quality again.
