Description
Technical field
The utility model relates to a kind of thermostatically-controlled equipment, more particularly, is a kind of thermostatically-controlled equipment of SMT tin cream spray printing.
Background technology
Point gum machine is a kind of injection-moulding device commonly used, uses very extensively, needs exactly the position of paster to put in advance a kind of special glue on pcb board, fixes surface mount elements, passes through wave-soldering after the curing again.The point adhesive curing of surface element has very consequence in the SMT technological process.And in a glue process, environment temperature is very large on the impact of the viscosity of glue and flow velocity, and temperature is crossed and lowly the wire drawing phenomenon can be occurred, and the glue flow velocity is excessively slow, will cause the electronic component bottom not to be filled and does not have the fully effect of protection; Excess Temperature can make glue solidify in advance, can't flow and stop up Glue dripping head, and these will directly cause a glue bad, thereby affect production procedure and product quality.Therefore, the effect of heating devcie of glue-dropping machine also seems particularly important.
The temperature requirements of SMT production technology tin cream is responsive, the thermostatic control system that need to be designed with, and the utility model is realized the temperature of jet-printing head materials part is added heat control by temperature controller and constant-temperature circuit.
The utility model content
It is a kind of easy and simple to handle that the purpose of this utility model is to provide, and can carry out Real-Time Monitoring and the thermostatically-controlled equipment of regulating the SMT tin cream spray printing that arranges.
For achieving the above object, the utility model has adopted following technical scheme:
A kind of thermostatically-controlled equipment of SMT tin cream spray printing, it is characterized in that: mainly consisted of by temperature controller, thermostatic control system and jet-printing head, temperature controller is carried out Real-Time Monitoring and regulate to be arranged by computing machine, and the work of temperature controller control thermostatic control system is provided with heat conductive rod at the afterbody of jet-printing head.
Described thermostatic control system is comprised of ADC converter, audio-frequency generator, temperature element and heating element, the ADC converter is converted to analog control signal with the digital controlled signal of temperature controller, act on temperature element and heating element, audio-frequency generator is carried out Real Time Monitoring and is reported to the police under the monitoring of temperature controller.
Described temperature element is positioned at the afterbody of the heat conductive rod of jet-printing head, and heating element is carried out temperature survey, and test result is fed back to audio-frequency generator carries out Real Time Monitoring.
Described heating element is positioned at the afterbody of jet-printing head heat conductive rod, and heat conductive rod is heated.
The utlity model has following beneficial effect:
(1) simple in structure, meet the responsive requirement of the temperature control of SMT production technology tin cream;
(2) easy and simple to handle, can carry out Real-Time Monitoring and regulate setting.
Description of drawings
Fig. 1 is one-piece construction figure of the present utility model.
Wherein, 1-computing machine, 2-temperature controller, 3-thermostatic control system, 4-ADC converter, 5-audio-frequency generator, 6-temperature element, 7-heating element, 8-jet-printing head, 9-heat conductive rod.
Embodiment
As shown in Figure 1, a kind of thermostatically-controlled equipment of SMT tin cream spray printing, it is characterized in that: mainly consisted of by temperature controller 2, thermostatic control system 3 and jet-printing head 8, temperature controller 2 is carried out Real-Time Monitoring and is regulated setting by computing machine 1,3 work of temperature controller 2 control thermostatic control systems are provided with heat conductive rod 9 at the afterbody of jet-printing head 8.Temperature controller is according to the temperature variation of working environment; in the inner generation of switch physical deformation, thereby produce some special effects, produce conducting or disconnect a series of Automatic Control Components that move; also be temperature detect switch (TDS), temperature protector, temperature controller, be called for short temperature controller.
Further, thermostatic control system 3 is comprised of ADC converter 4, audio-frequency generator 5, temperature element 6 and heating element 7, ADC converter 4 is converted to analog control signal with the digital controlled signal of temperature controller 2, act on temperature element 6 and heating element 7, audio-frequency generator 5 is carried out Real Time Monitoring and is reported to the police under the monitoring of temperature controller 2.The effect of A/D conversion is that Time Continuous, amplitude also continuous analog quantity are converted to also discrete digital signal of time discrete, amplitude, and therefore, the A/D conversion generally will be through taking a sample, keep, quantize and encode 4 processes.
Further, temperature element 6 is positioned at the afterbody of the heat conductive rod 9 of jet-printing head 8, and heating element 7 is carried out temperature survey, and test result is fed back to audio-frequency generator 5 carries out Real Time Monitoring.
Preferably, heating element 7 is positioned at the afterbody of jet-printing head 8 heat conductive rods 9, and heat conductive rod 9 is heated.
In actual spray printing process, in the software systems of computing machine 1, carry out respectively first the setting of heating power and alarm temperature.Then, the software systems of computing machine 1 are sent control command, the control command of controller 2 receiving computers 1, and send the control figure signal, ADC converter 4 is converted to the control simulation signal with the control figure signal, drive respectively temperature element 6 and heating element 7 work, temperature element 6 with the temperature survey of heat conductive rod out and feeds back to audio-frequency generator 5, if be higher than when setting alarm temperature, audio-frequency generator 5 sends the warning that pipes, heating element 7 stopped heating work; Otherwise heating element 7 continues heating, until be heated to just stopped heating of alarm temperature.
The responsive requirement of temperature control that the utility model satisfies SMT production technology tin cream can realize that temperature is in setting value ± 0.2.The control of ℃ scope is carried out Real-Time Monitoring by computer software and is arranged with regulating.
