Description

Technical Field

[0001] The utility model relates to the technical field of thermistor production, in particular to a thermistor chip sorting machine. Background Art

[0002] A thermistor is a sensor resistor whose resistance value changes with temperature. It is divided into positive temperature coefficient thermistors and negative temperature coefficient thermistors according to different temperature coefficients. The resistance value of a positive temperature coefficient thermistor increases with increasing temperature, while the resistance value of a negative temperature coefficient thermistor decreases with increasing temperature. They are both semiconductor devices.

[0003] Thermistors need to be sorted during production, and those with appearance defects can be sorted out. However, when the current sorting machines are used, the thermistors are usually spread out for manual sorting. Manual sorting may not only result in missed selections, but also greatly affects the sorting efficiency. Therefore, we propose a thermistor chip sorting machine to solve the above problems.

DETAILED DESCRIPTION

[0018] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 In the utility model, a thermistor chip sorting machine includes a bottom plate 1, a support 2 is fixedly connected to the upper surface of the bottom plate 1, and the left and right sides of the support 2 are rotatably connected with a rotating shaft 15, and the ends of the two rotating shafts 15 that are away from each other are fixedly connected with a support plate 14, and the upper surfaces of the two support plates 14 are commonly fixedly connected with a carrier plate 5, and the rotating shaft 15 can drive the carrier plate 5 to deflect, so that the thermistor chips can be classified. A conveyor belt 4 is arranged on the left side of the carrier plate 5, and the conveyor belt 4 is located above the carrier plate 5. The conveyor belt 4 can be used to transport the thermistor chips, replacing the manual operation of the thermistor chips. The resistor chip is placed on the carrier 5, and a baffle 12 is fixedly connected to the upper surface of the carrier 5. The baffle 12 is located on the right side of the carrier 5. The baffle 12 can be used to block the right side of the carrier 5 to prevent the thermistor chip from sliding when it falls onto the carrier 5. Two limit plates 13 are fixedly connected to the bottom surface of the carrier 5. The two limit plates 13 are respectively located on the front side of the pillar 2 and the back side of the pillar 2. The limit plates 13 are located below the carrier 5. When the carrier 5 deflects, the limit plates 13 will first contact the pillar 2, and then they can form a barrier for the carrier 5 to prevent the carrier 5 from deflecting too much.

[0021] One of the two rotating shafts 15 passes through the support plate 14 and is fixedly connected to the first gear 16. The upper surface of the base plate 1 is fixedly connected to the L-shaped plate 6. The bottom surface of the L-shaped plate 6 is installed with an appearance inspection device 8. The appearance inspection device 8 can be used to inspect the appearance of the thermistor chip and distinguish the damage to the appearance of the thermistor chip.

[0022] A motor 10 is installed on the left side of the L-shaped plate 6, and a second gear 11 is fixedly connected to the output end of the motor 10. A single-chip microcomputer 9 is installed on the left side of the L-shaped plate 6. The appearance detection device 8 can send a signal to the single-chip microcomputer 9. The single-chip microcomputer 9 will control the motor 10 to rotate forward and reverse according to the signal sent by the appearance detection device 8, thereby driving the carrier board 5 to deflect in different directions, so as to complete the sorting of thermistor chips.

[0023] The front and back sides of the carrier board 5 are both provided with guide frames 7, which are located at both sides of the carrier board 5. When the carrier board 5 is deflected, the thermistor chip on the carrier board 5 will enter the guide frames 7 to prevent the thermistor chip from deviating.

[0024] Two collecting frames 3 are placed on the upper surface of the bottom plate 1 , and the sorted thermistor chips can be collected by using the provided collecting frames 3 , so that the workers can conveniently process the sorted thermistor chips in a centralized manner.

[0025] The working principle of the utility model is: when in use, the thermistor chip is conveyed to the carrier plate 5 by controlling the conveyor belt 4 to work, and then the appearance detection device 8 will detect the thermistor chip on the carrier plate 5. When it is detected that there is no defect in the appearance, the single-chip microcomputer 9 will control the motor 10 to rotate forward, and at the same time the second gear 11 will drive the first gear 16 to rotate, and the first gear 16 will drive the shaft 15 and the carrier plate 5 to tilt backward, and the thermistor chip on the carrier plate 5 will fall into the collection frame 3. On the contrary, when a defect is detected, the single-chip microcomputer 9 will control the motor 10 to flip, and the carrier plate 5 will tilt forward, so that the thermistor chips can be classified and collected, and the classification efficiency can be guaranteed.
