Description

Technical fields:

[0001] This utility model relates to the field of resistance technology, and in particular to a feeding device for thermistors. Background technology:

[0002] A thermistor is a sensor resistor whose resistance changes with temperature. It is small in size and can measure the temperature of gaps, cavities, and blood vessels in living organisms that other thermometers cannot measure. It also has good stability and strong overload capacity.

[0003] In the production of thermistors, a resistor forming machine is required. The resistor forming machine is generally a belt type. The resistor leads are cut off by the forming machine. However, because the thermistors produced are of different models and sizes, the resistors of different types and sizes are piled up together after forming. During feeding, manual screening is required to select resistors that meet the specifications and sizes required for the current batch. This is not only time-consuming and labor-intensive, but also affects the processing efficiency. Summary of the Invention:

[0004] The purpose of this invention is to provide a feeding device for thermistors that addresses the shortcomings of existing technologies. This device can automatically sieve and feed the formed resistors without manual operation, thus effectively improving feeding efficiency.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a feeding device for thermistors, comprising a support base, a support frame, a storage support seat, a resistor sieving mechanism, and a resistor discharging mechanism. The support frame is disposed on the support base, the storage support seat is disposed on the support base, the resistor sieving mechanism is disposed on the storage support seat, and the resistor discharging mechanism is disposed on the support frame. The resistor sieving mechanism is used to sieve and discharge resistors stored in the storage tank, and the resistor discharging mechanism is used to transport the resistors sieved by the resistor sieving mechanism to the next production line. The resistor sieving mechanism includes a vibrating plate, a spiral track, and a screening baffle. The vibrating plate is disposed on the storage support seat, and the spiral track starts from the bottom of the vibrating plate and winds around the inner wall of the vibrating plate from bottom to top. The screening baffle is disposed on the spiral track and is perpendicular to the inner wall of the vibrating plate. The bottom of the screening baffle is provided with a screening notch that matches the size of the thermistor.

[0006] A further improvement to the above scheme is that several screening notches are evenly arranged side by side along the bottom of the screen.

[0007] A further improvement to the above scheme is that the screening baffle is detachably mounted on the spiral track.

[0008] A further improvement to the above solution is that the resistor discharge mechanism includes an X-axis guide rail, an X-axis slider, an X-axis drive assembly, a discharge base, a discharge push rod, a discharge drive assembly, a feed pipe, and a limiting assembly. The X-axis guide rail is mounted on the support base, and the X-axis slider is slidably mounted on the X-axis guide rail. The power output end of the X-axis drive assembly drives and connects to the X-axis slider. The discharge base is mounted on the X-axis slider, and a discharge channel is provided through the discharge base along the X-axis direction. A feed inlet is provided at the top of the discharge channel. The discharge push rod is slidably mounted in the discharge channel, and the power output end of the discharge drive assembly drives and connects to the discharge push rod. The feed pipe is located above the discharge base, with its inlet end connected to the outlet of the spiral track and its outlet end connected to the feed inlet. The horizontal height of the inlet end of the feed pipe is higher than the horizontal height of the outlet end.

[0009] A further improvement to the above solution is that the X-axis drive assembly includes an X-axis drive cylinder, a piston rod, and a drive connector. The X-axis drive cylinder is fixedly mounted on the bottom of the support frame, and the piston rod is located at the power output end of the X-axis drive cylinder. The X-axis drive cylinder drives and connects to the piston rod. The tail of the piston rod is fixedly connected to one end of the drive connector, and the other end of the drive connector is fixedly connected to the X-axis slider. The X-axis drive cylinder drives the piston rod to reciprocate along the X-axis, thereby driving the X-axis slider to slide along the X-axis guide rail.

[0010] A further improvement to the above solution is that the discharge drive assembly includes a push rod motor, which is disposed above the support frame, and the power output end of the push rod motor drives and connects to the discharge push rod.

[0011] A further improvement to the above solution is that the limiting component includes a limiting slider, a limiting drive motor, a limiting push rod, and a limiting plate. The limiting slider is slidably mounted on the X-axis guide rail. The limiting drive motor is mounted on the push rod motor. The limiting push rod is mounted on the power output end of the limiting drive motor. The limiting drive motor drives and connects to the front end of the limiting push rod. The limiting plate is fixedly mounted on the side of the discharge base. The rear end of the limiting push rod is fixedly connected to the limiting plate.

[0012] A further improvement to the above solution is that the bottom of the vibratory feeder is also provided with shock-absorbing rubber pads.

[0013] The beneficial effects of this utility model are as follows: This utility model includes a support base, a support frame, a storage support seat, a resistance screening mechanism, and a resistance discharge mechanism. The support frame is disposed on the support base, the storage support seat is disposed on the support base, the resistance screening mechanism is disposed on the storage support seat, and the resistance discharge mechanism is disposed on the support frame. The resistance screening mechanism is used to screen and discharge the resistors stored in the storage tank, and the resistance discharge mechanism is used to transport the resistors screened by the resistance screening mechanism to the next production line. The resistance screening mechanism includes a vibrating plate, a spiral track, and a screening baffle. The vibrating plate is disposed on the storage support seat, and the spiral track starts from the bottom of the vibrating plate and winds around the inner wall of the vibrating plate from bottom to top. The screening baffle is disposed on the spiral track and is perpendicular to the inner wall of the vibrating plate. The bottom of the screening baffle is provided with a screening notch that matches the size of the thermistor.

[0014] This utility model is equipped with a resistance screening mechanism, including a vibrating plate, a spiral track, and screening baffles. When the resistors pass through the screening baffles on the spiral track, resistors that do not meet the specifications are blocked by the screening gaps at the bottom of the screening baffles that match the size of the thermistors. Resistors that meet the specifications of the current batch pass through automatically. The resistors that meet the specifications pass through and enter the next production line through the resistor discharge mechanism. This realizes the automation of resistance screening, replaces manual screening, reduces labor costs, improves screening efficiency, and is easy to use. Attached image description:
