Detailed description of the invention
Fig. 1 is that SMT printing machine tin cream backs detecting system schematic diagram in the utility model embodiment；
Fig. 2 is that SMT printing machine tin cream backs the schematic diagram of detection method in the utility model embodiment.
Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched
The embodiment stated is a part of the embodiment of the utility model, instead of all the embodiments.Based on the reality in the utility model
Apply example, those of ordinary skill in the art's every other embodiment obtained without making creative work, all
Belong to the range of the utility model protection.
The utility model provides a kind of SMT printing machine tin cream and backs detection system, as shown in Figure 1, the system includes: light
Electric transducer, comparator, controller and warning device,
The comparator is connect with the photoelectric sensor, the tin cream that the comparator detects the photoelectric sensor
Print pass is compared with preset times, generates control signal；
The controller is connect with the comparator and the warning device respectively, and the controller receives the control
When signal, the operation or out of service of printing machine, and the opening and closing of control warning device are controlled.
In embodiments herein, by detecting whether print pass reaches preset times, when reaching preset times,
Control printing machine is out of service and issue early warning, and prompting need to back tin cream in time, avoids the occurrence of tin cream leakage brush, few tin feelings
Then condition judges whether to be operated according to preset requirement, printing machine resumes operation after executing as requested.The utility model
Traditional count mode is changed to autonomous detection pattern by the technical solution of offer, by detecting and calculating the paste solder printing frequency to print
Brush machine is controlled and makes corresponding prompting, it is ensured that paste solder printing frequency accuracy, validity, mistake proofing.Reduce artificial behaviour
The extraneous factors such as work lead to tin cream leakage brush, few tin hidden danger.
In some embodiments of the present application, warning device includes: audible alarm unit and light warning device.
Wherein, audible alarm unit can be buzzer, and light warning device can be charactron.
In some embodiments of the present application, the system further include: display screen, the display screen and the photoelectric sensor
Connection, the display screen show the number for the paste solder printing that the photoelectric sensor detects.
In some embodiments of the present application, the system further include: tin cream backs device, and the tin cream backs device and institute
Controller connection is stated, when the controller receives control signal, the tin cream is controlled and backs the opening or closing of device.
The utility model implementation method is as shown in Figure 2:
Detect the number of paste solder printing；
When print pass reaches preset times, printing machine is out of service and issues warning note；
