Description

Technical Field

[0001] This utility model relates to the field of thermistor detection technology, and in particular to a thermistor safety detection device. Background Technology

[0002] Thermistors, as temperature-sensitive semiconductor resistors, are widely used in temperature monitoring and overheat protection scenarios of electronic equipment. Their performance stability is directly related to the safe operation of the equipment. Therefore, strict safety testing is required before production and use, including testing of multiple indicators such as resistance accuracy, temperature response characteristics, and withstand voltage performance.

[0003] However, in the existing technology, thermistor detection mostly relies on manual operation, which has problems such as low detection efficiency and large human intervention error. In addition, the feeding, positioning, pressure application and unloading processes lack automated coordination, which can easily lead to distorted detection data due to inaccurate positioning. At the same time, the collected materials after detection are scattered, which increases the subsequent processing cost. Utility Model Content

[0004] The purpose of this invention is to solve the problems of low automation in thermistor detection, significant impact of manual operation on detection accuracy, poor coordination among various links, and inconvenience in material collection in the existing technology, and to propose a thermistor safety detection device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a thermistor safety detection device, comprising a frame and a control console fixedly installed on its top, a detection mechanism fixedly installed on the upper surface of the frame, the detection mechanism comprising a support platform, a detection platform, and a vertical rod slidably connected inside the detection platform, the detection platform being fixedly installed on the top of the support platform, a pressure rod being fixedly installed on the top of the vertical rod, the pressure rod being located above the detection platform, a guide platform being fixedly installed on the upper surface of the detection platform, a detector being fixedly installed at one end of the upper surface of the detection platform, and the guide platform being located below the detector.

[0006] Preferably, a first electric cylinder is fixedly installed at the other end of the upper surface of the testing platform, and the first electric cylinder and the guide platform are located on the same straight line.

[0007] Preferably, a motor and belt drive assembly are fixedly installed on the upper surface of the support platform, and one end of the belt of the motor and belt drive assembly is connected to a pulley, which is located below the testing platform.

[0008] Preferably, a positioning frame is fixedly connected between the testing platform and the support platform, and the rotating wheel is rotatably installed on the inner side of the positioning frame.

[0009] Preferably, a transmission rod is rotatably connected to the eccentric part of the wheel, and one end of the transmission rod is rotatably connected to the bottom end of the vertical rod.

[0010] Preferably, a feeding cylinder is fixedly connected to one side of the detector, and the feeding cylinder is located at the discharge port of the guide table.

[0011] Preferably, a receiving box is placed on the upper surface of the support platform, and grippers are provided on both sides of the receiving box.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, the rotating wheel is driven by a belt. Since one end of the transmission rod is rotatably connected to the eccentric part of the rotating wheel, the rotational motion of the rotating wheel is converted into the up-and-down reciprocating sliding of the vertical rod through the transmission rod. During detection, a stable pressure can be applied to the thermistor placed on the guide platform to ensure good contact between the thermistor and the detector, reduce errors caused by poor contact, improve detection efficiency and accuracy, and reduce errors and labor intensity of manual operation.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a thermistor safety detection device, including a frame and a control console 1 fixedly installed on its top. A detection mechanism 2 is fixedly installed on the upper surface of the frame. The detection mechanism 2 includes a support platform 21, a detection platform 22, and a vertical rod 29 slidably connected inside the detection platform 22. The detection platform 22 is fixedly installed on the top of the support platform 21. A pressure rod 213 is fixedly installed on the top of the vertical rod 29. The pressure rod 213 is located above the detection platform 22. A guide platform 212 is fixedly installed on the upper surface of the detection platform 22. A detector 23 is fixedly installed at one end of the upper surface of the detection platform 22. The guide platform 212 is located below the detector 23. A motor and belt drive assembly 26 is fixedly installed on the upper surface of the support platform 21. One end of the belt of the motor and belt drive assembly 26 is connected to a pulley 27. The pulley 27 is located below the detection platform 22. A transmission rod 28 is rotatably connected to the eccentric part of the pulley 27. One end of the transmission rod 28 is rotatably connected to the bottom end of the vertical rod 29.

[0023] The specific setup and function of this embodiment are described below. The control console 1 controls the overall equipment operation. The support platform 21 in the detection mechanism 2 provides the mounting base for each component. The detection platform 22 serves as the main platform for the detection operation. The guide platform 212 above it positions and guides the thermistor, facilitating accurate detection by the detector 23. After the motor and belt drive assembly 26 starts, it drives the rotating wheel 27 to rotate via the belt. Since one end of the transmission rod 28 is rotatably connected to the eccentric part of the rotating wheel 27, the rotational motion of the rotating wheel 27 is converted into the up-and-down reciprocating sliding of the vertical rod 29 through the transmission rod 28. The pressure rod 213 at the top of the vertical rod 29 moves synchronously with the vertical rod 29, applying stable pressure to the thermistor placed on the guide platform 212 during detection, ensuring good contact between the thermistor and the detector 23. Simultaneously, the motor and belt drive assembly 26... The belt drive allows for stable adjustment of the rotation speed of the rotating wheel 27, thereby controlling the movement frequency and amplitude of the vertical rod 29 and the pressure rod 213, achieving dynamic detection of the thermistors. The support platform 21 ensures the overall stability of the detection mechanism 2. The detection platform 22 and the guide platform 212 ensure accurate positioning during thermistor detection, avoiding the impact of positional deviation on the detection results. The transmission system, consisting of the motor and belt drive assembly 26, the rotating wheel 27, and the transmission rod 28, can efficiently convert the rotational motion into the reciprocating motion of the vertical rod 29, driving the pressure rod 213 to apply stable pressure, ensuring good contact between the thermistor and the detector 23, and reducing errors caused by poor contact. With the coordinated work of all components, under the control of the control console 1, automated and precise detection of thermistors is achieved, improving detection efficiency and accuracy, and reducing errors and labor intensity caused by manual operation.

[0024] Example 2: Figure 2 , Figure 3 and Figure 4 As shown, a first electric cylinder 210 is fixedly installed at the other end of the upper surface of the detection table 22. The first electric cylinder 210 and the guide table 212 are on the same straight line. A positioning frame 214 is fixedly connected between the detection table 22 and the support table 21. The rotating wheel 27 is rotatably installed inside the positioning frame 214. A feeding cylinder 24 is fixedly connected to one side of the detector 23. The feeding cylinder 24 is located at the discharge port of the guide table 212. A receiving box 25 is placed on the upper surface of the support table 21. Grippers 211 are provided on both sides of the receiving box 25.

[0025] The overall implementation achieves the following effect: the first electric cylinder 210 on the testing table 22 is aligned with the guide table 212, which can push the part to be tested along the guide table 212 to the testing position. The positioning frame 214 fixes the testing table 22 and the support table 21, and provides rotational support for the rotating wheel 27. After testing, the part enters the feeding cylinder 24 through the discharge port of the guide table 212, and finally falls into the receiving box 25 on the support table 21. The grippers 211 on both sides of the receiving box 25 can fix its position. The first electric cylinder 210 realizes automatic feeding, improving the continuity of testing. The positioning frame 214 enhances the structural stability and ensures the accurate operation of the rotating wheel 27 and other parts. The feeding cylinder 24 guides the parts to fall in an orderly manner to avoid collisions. The grippers 211 fix the receiving box 25 to prevent displacement and missed connection. Through the cooperation of various parts, the automation level and testing efficiency are improved, and the error of manual intervention is reduced.

[0026] The operation and working principle of this device are as follows: First, start the device via the control console 1. Place the thermistor to be tested on the guide platform 212 of the detection platform 22. The first electric cylinder 210 starts and pushes the thermistor along the guide platform 212 to the detection position below the detector 23. Then, the motor and belt drive assembly 26 starts, driving the rotating wheel 27 inside the positioning frame 214 to rotate via the belt. The transmission rod 28 at the eccentric part of the rotating wheel 27 converts the rotational motion into the up-and-down reciprocating sliding of the vertical rod 29, causing the pressure rod 213 at the top of the vertical rod 29 to press down, ensuring that the thermistor is in close contact with the detector 23 to complete the detection. After the detection is completed, the pressure rod 213 is reset, and the thermistor continues to move along the guide platform 212, enters the discharge cylinder 24 through its outlet, and falls into the receiving box 25 fixed by the clamps 211 on both sides of the support platform 21. The whole process is automatically completed under the control of the control console 1, realizing continuous and accurate detection of the thermistor.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
