Description

Technical Field

[0001] The utility model relates to the technical field of high-temperature resistor classification equipment, in particular to a linear high-temperature thermistor classification machine. Background Art

[0002] A high-temperature thermistor is a sensor resistor whose resistance value changes with the change of the operating temperature. Its own heat-resistant temperature is usually between 10 degrees and 180 degrees. Different high-temperature thermistor resistance ranges require precision. When measuring, the measured resistance value of the high-temperature thermistor is compared with the resistance value of the high-temperature thermistor used as a calibration, and they are classified and cut according to the range of the detection values.

[0003] At present, manual detection and classification are usually used in the market for screening and classification, and the detected temperature range is 10 degrees to 100 degrees. The detection and classification speed is slow and requires a lot of manpower, which wastes time and corporate costs.

[0071] Next, the jig with the thermistors will first pass through the leveling mechanism 400, in which the positions of the thermistors are arranged to make their height and flatness uniform, and then the jig will be transported to the next testing mechanism 500 for testing and analysis, wherein a comparison component 520 is provided in the testing mechanism 500, in which a group of thermistors with standard values ​​are provided as a reference group for comparison and analysis, and the results of the tested thermistors are uploaded, analyzed and compared by the central control system 130, and a material picking signal is sent to the material picking mechanism 600.

[0072] Then, the lower conveying track 220 will convey the tested jigs with thermistors backwards, so that they pass through the oil receiving groove 540 and stop moving forward, so that the oil attached to the thermistors can drip down and be collected, and then convey them to the material taking mechanism 600 for taking materials. At this time, the material taking mechanism 600 receives the material taking information sent by the central control system 130, and takes and discharges thermistors at different positions, so that the tested thermistors can be accurately placed in the NG material box 650, the high material box 650, the low material box 650 or the OK material box 650;

[0073] Since the test NG material collection component 610 and the test low material collection component 630 are located at the rear and lower part of the lower conveying track 220, when the material collection clamping claw 660 takes out the thermistors in both cases, the jig with the remaining thermistors will be moved upward through the jig lifting mechanism 700 and placed in the upper conveying track 210. At this time, the test high material collection component 620 and the test OK material collection component 640 will classify the thermistors and collect the materials, thereby completing the detection classification.

[0074] After the tested thermistors are sorted and picked up by the picking mechanism 600, the jig moves forward along the upper conveying track 210, and passes through the residual material sensor 900. The residual material sensor 900 performs a sensing check on the jig to check whether there are any missing thermistors and uploads the detection information. If any missing thermistors are found, an alarm will be issued in time through the central control system 130 to remind the operator to take out the missing thermistors.

[0075] At the head end of the upper conveying track 210, the idle jig above is lowered by the jig lowering mechanism 800, and the jig is placed on the jig unloading component 320 through the unloading transfer component 330, waiting for secondary reuse.

[0076] The above are only preferred embodiments of the present invention, and only specifically describe the technical principles of the present invention. These descriptions are only for the purpose of explaining the principles of the present invention, and cannot be interpreted as limiting the scope of protection of the present invention in any way. Based on the explanation here, any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention, and other specific implementation methods of the present invention that can be associated with by technicians in this field without creative labor, should be included in the scope of protection of the present invention.
