Abstract
The utility model discloses a kind of automatic liquid dispenser, comprise ARM control panel (1) and band EEPROM (2), described ARM control panel (1) is connected electromagnetic valve (3), stepper motor (4), encoder (5) and external balance (6) respectively, encoder (5) connects stepper motor (4), stepper motor (4) connects injector (7), and the upper limit position switch (8) of injector (7) is connected ARM control panel (1) respectively with lower position switch (9); Band EEPROM (2) connects ARM control panel (1).The utility model can realize automatic liquid matching, can not only improve precision, and operation can be made more humane, reduces costs simultaneously.
Description
Technical field
The utility model relates to a kind of chemical dosing equipment, particularly a kind of automatic liquid dispenser.
Background technology
The liquid dispenser used in the market, mostly adopt motor or peristaltic pump, then carry out opened loop control in conjunction with drive circuit, precision is lower.This series products is mainly by import in addition, and expensive, cost is high, and operation is hommization not also.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of automatic liquid dispenser, can not only improve precision, can reduce costs simultaneously, thus overcome above-mentioned the deficiencies in the prior art.
For solving the problems of the technologies described above, the technical solution of the utility model is as follows:
A kind of automatic liquid dispenser, comprise ARM control panel and band EEPROM, described ARM control panel is connected electromagnetic valve, stepper motor, encoder and external balance respectively, encoder connects stepper motor, stepper motor connects injector, and the upper limit position switch of injector is connected ARM control panel respectively with lower position switch; Band EEPROM connects ARM control panel.
In above-mentioned automatic liquid dispenser, also comprise liquid crystal display, liquid crystal display connects ARM control panel.
The beneficial effects of the utility model: compared with prior art, the open loop control mode of traditional stepper motor is changed into closed-loop control by the utility model, namely while stepper motor work, the duty of stepper motor is detected in real time with code devices, if there is step-out phenomenon, at once the step number of losing is supplemented, so just reach and put forward high-precision object, through actual measurement, precision of the present utility model can bring up to 1 ‰, achieve the production domesticization of equipment, reduce cost.For strengthening man-machine interaction, the utility model adopts very color liquid crystal touch screen, in automatic liquid matching link, can carry out communication, realize the automation of dosing with balance.Like this, the object making equipment more humane is just reached.
Accompanying drawing explanation
Fig. 1 is structure principle chart of the present utility model.
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
Detailed description of the invention
Embodiment 1.As shown in Figure 1, comprise ARM control panel 1 and band EEPROM 2 (being called for short EEPROM), described ARM control panel 1 is connected electromagnetic valve 3, stepper motor 4, encoder 5 and external balance 6 respectively, encoder 5 connects stepper motor 4, stepper motor 4 connects injector 7 (syringe), and the upper limit position switch 8 of injector 7 (syringe) is connected ARM control panel 1 respectively with lower position switch 9; Encoder 5 is used for detecting stepper motor 4 distance of passing by, and upper limit position switch 8 and lower position switch 9 are used for detecting the piston position of injector 7 (syringe); Band EEPROM 2 connects ARM control panel 1.For convenience of man-machine interaction, be also provided with liquid crystal touch screen 10, liquid crystal touch screen 10 connects ARM control panel 1.
Operation principle: after start, equipment loads initialization data from band EEPROM 2, and self-inspection; After self-inspection completes, by the state of upper limit of detection bit switch 8, lower position switch 9, judge the piston position of injector 7 (syringe), then according to the position of piston, by the changing interface of liquid crystal touch screen 10 to corresponding display state; Under different interfaces, can proceed as follows respectively: liquid feeding, dosing, calibration, thus realize automatic liquid matching.
Embodiment of the present utility model is not limited to above-described embodiment, and the various changes made under the prerequisite not departing from the utility model aim all belong within protection domain of the present utility model.
Claims (2)
1. an automatic liquid dispenser, comprise ARM control panel (1) and band EEPROM (2), it is characterized in that: described ARM control panel (1) is connected electromagnetic valve (3), stepper motor (4), encoder (5) and external balance (6) respectively, encoder (5) connects stepper motor (4), stepper motor (4) connects injector (7), and the upper limit position switch (8) of injector (7) is connected ARM control panel (1) respectively with lower position switch (9); Band EEPROM (2) connects ARM control panel (1).
2. automatic liquid dispenser according to claim 1, is characterized in that: also comprise liquid crystal touch screen (10), and liquid crystal touch screen (10) connects ARM control panel (1).
