Description

Technical Field

[0001] This application relates to the field of resistance sorting and testing technology, specifically a rapid sorting and testing fixture for thermistors. Background Technology

[0002] Thermistor production is a systematic process from raw material processing to finished product testing. The core is to precisely control process parameters to manufacture products that meet resistance and temperature characteristics requirements. Sorting and testing is a critical quality control step in the later stages of production. In the thermistor manufacturing process, the head diameter is one of the key physical parameters affecting product performance, assembly compatibility, and application reliability. Screening large-diameter and small-diameter thermistors is labor-intensive and costly. Manual sorting requires a large number of operators to continuously repeat a single action, easily leading to occupational health problems such as hand strain and visual fatigue. Furthermore, additional quality inspectors are needed to perform secondary verification of the sorting results, resulting in high labor costs. Therefore, those skilled in the art have provided a rapid sorting and testing fixture for thermistors to solve the problems mentioned in the background. Utility Model Content

[0003] The purpose of this invention is to provide a rapid sorting and testing fixture for thermistors to solve the problems mentioned in the background art.

[0015] Please see Figs. 1-4 In this embodiment of the present invention, a rapid sorting test rack for thermistors includes a base plate 1. A fixing plate 25 is fixedly connected to the upper surface of the base plate 1. A first slide rail 21 is formed on the outer surface of the fixing plate 25. Two first sliders 22 are slidably connected inside the first slide rail 21. A scraper 26 is fixedly connected to one side of each of the two first sliders 22. A connecting rod 23 is fixedly connected between the two first sliders 22. A cylinder 24 is fixedly connected to the inner wall of the first slide rail 21. The output end of the cylinder 24 is fixedly connected to the outer surface of one of the first sliders 22. The upper surface of the base plate 1 is fixedly connected to the fixing plate 25. A workbench 20 is connected to the base plate 1. A fixed frame 3 is fixedly connected to the upper surface of the base plate 1. A controller 2 is installed on the outer surface of the fixed frame 3. An extension rod 11 is fixedly connected inside the fixed frame 3. An industrial camera 12 is fixedly connected to the bottom surface of the extension rod 11. When the thermistor is transported to the designated detection area of ​​the workbench 20, the operator starts the detection program through the controller 2 on the outer surface of the fixed frame 3. The industrial camera 12 fixed on the bottom surface of the extension rod 11 inside the fixed frame 3 starts to work, accurately photographs and collects data on the diameter of the thermistor head, and feeds back the detection results to the controller 2 in real time.

[0016] A first material hole 9 is provided on the upper surface of the base plate 1. Two second slides 13 are provided on the inner wall of the first material hole 9. A second slider 15 is slidably connected inside each of the two second slides 13. A first material box 14 is fixedly connected between the two second sliders 15. A second material hole 19 is provided on the upper surface of the base plate 1. Two third slides 18 are provided on the inner wall of the second material hole 19. A third slider 16 is slidably connected inside each of the two third slides 18. A second material box 17 is fixedly connected between the two third sliders 16. The controller 2 judges the size data fed back by the industrial camera 12. If the thermistor meets the preset first specification standard, the controller 2 sends a command to the cylinder 24. The output end of the cylinder 24 pushes the first slider 22 connected to it along the first slide on the fixed plate 25. One slide 21 slides, driving another first slider 22 to move synchronously via the connecting rod 23. The scraper 26 on one side of the two first sliders 22 pushes the thermistor of the specified specification, causing it to fall into the first material box 14 below through the first material hole 9. If the thermistor meets the preset second specification standard, the controller 2 controls the cylinder 24 to drive the scraper 26 to move in another direction, pushing the thermistor to the second material hole 19, and finally falling into the second material box 17. The first material box 14 is slidably connected to the second slide 13 on the inner wall of the first material hole 9 via the second slider 15. The second material box 17 is slidably connected to the third slide 18 on the inner wall of the second material hole 19 via the third slider 16. When the material box is full of thermistors, the staff can directly pull out the material box to complete the cleaning and replacement.

[0017] Four support rods 6 are fixedly connected to the upper surface of the base plate 1. The upper surfaces of the four support rods 6 are hinged to a bearing plate 5 via pins. A baffle 4 and a flow limiting plate 10 are fixedly connected to the upper surface of the bearing plate 5. Four support legs 7 are fixedly connected to the bottom surface of the base plate 1. Anti-slip pads 8 are installed on the bottom surface of each of the four support legs 7. The thermistors to be sorted are placed on the bearing plate 5. The bearing plate 5 is hinged to the four support rods 6 via pins, and the tilt angle can be adjusted according to actual needs. The baffle 4 and the flow limiting plate 10 on its surface work together to limit and regulate the thermistors, preventing the material from accumulating or shifting during the conveying process, and ensuring that the material is conveyed to the workbench 20 in an orderly manner. At the same time, the anti-slip pads 8 on the bottom of the four support legs 7 on the bottom surface of the base plate 1 enhance the overall placement stability of the equipment, preventing the equipment from shifting due to vibration or external force during operation, and ensuring the continuous and stable operation of the entire sorting process.

[0018] The working principle of this utility model is as follows: When the device is working, the thermistors to be sorted are first placed on the support plate 5. The support plate 5 is hinged to four support rods 6 by pins, and the tilt angle can be adjusted. The baffle 4 and the flow limiting plate 10 on its surface regulate the material and prevent accumulation and displacement, so that the material is transported to the workbench 20 in an orderly manner. When the material reaches the detection area of ​​the workbench 20, the operator starts the program through the controller 2 outside the fixed frame 3. The industrial camera 12 on the bottom surface of the extension rod 11 inside the fixed frame 3 takes pictures and collects the diameter data of the thermistor head, and feeds it back to the controller 2 in real time. The controller 2 judges based on the data. If it meets the requirements of the first step, the thermistor head diameter data is determined. If the specifications are met, the cylinder 24 is instructed to drive the first slider 22 to slide along the first slide rail 21 of the fixed plate 25. The connecting rod 23 drives another first slider 22 and scraper 26 to move, pushing the material through the first material hole 9 into the first material box 14. If the specifications are met, the material is pushed through the second material hole 19 into the second material box 17. The first material box 14 is pulled out and replaced by the second slider 15 cooperating with the second slide rail 13, and the second material box 17 is pulled out and replaced by the third slider 16 cooperating with the third slide rail 18. The anti-slip pads 8 of the four support legs 7 on the bottom surface of the base plate 1 ensure the stable operation of the equipment.

[0019] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
