Description

Technical Field

[0001] This invention relates to the field of temperature instrument manufacturing equipment technology, specifically a temperature instrument error calibration device. Background Technology

[0002] Temperature instruments are widely used in industrial production, scientific research experiments, medical testing, and many other fields. Their measurement accuracy directly affects production safety, experimental results, and product quality. Therefore, temperature instruments must undergo rigorous error calibration before leaving the factory or during periodic verification. Currently, most temperature instrument calibrations are performed manually or using semi-automated equipment. During the calibration process, the temperature instruments must be placed one by one at the calibration station, and their posture must be manually adjusted to ensure that the temperature sensor is aligned with the heating element. Then, the deviation between the instrument reading and the standard temperature is manually monitored to determine the error and make subsequent corrections.

[0003] With the increase in the production of temperature instruments, traditional calibration methods can no longer meet the needs of mass production. Although existing semi-automatic calibration equipment can realize some of the functions of conveying and calibration, it still has shortcomings in terms of conveying stability, temperature transmission uniformity and automation connection, which makes it difficult to further improve calibration efficiency and calibration accuracy, and cannot adapt to the needs of large-scale and high-precision calibration.

[0004] The existing temperature instrument error calibration process has the following technical problems: First, manual or semi-automatic conveying methods are difficult to achieve stable batch conveying of temperature instruments. During the conveying process, instruments are prone to offset or tipping, resulting in inaccurate alignment at the calibration station. This not only affects the continuity of calibration but also reduces calibration efficiency. Second, the fit between the temperature sensor and the heating element is insufficient, resulting in gaps. This leads to significant heat loss during heat transfer, uneven and unstable temperature transfer, and consequently, large calibration errors, affecting calibration accuracy. Therefore, this invention provides a temperature instrument error calibration device to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a temperature instrument error calibration device to address the problems in existing temperature instrument error calibration processes, such as the difficulty in achieving stable batch transport of instruments using manual or semi-automatic conveying methods, the tendency for instruments to tip over, insufficient contact between the temperature sensor and the heating element, and uneven heat transfer.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a temperature instrument error calibration device, comprising: a workbench and two conveyor frames fixedly connected to the top of the workbench, wherein a fixed seat is fixedly connected to one side of each conveyor frame, and a clamping assembly is provided on the top of the fixed seat; A plurality of temperature instruments are provided and placed above the conveyor frame. The inner side of the conveyor frame is provided with a conveying assembly for conveying the temperature instruments. A knob is installed at the front end of the temperature instrument and is rotatably connected to the temperature instrument. A temperature sensor is installed at the detection part of the temperature instrument. A heating auxiliary component for heating the temperature sensor is provided at the bottom of the workbench below the temperature sensor.

[0007] As a further embodiment of the present invention: the clamping assembly includes a first electric push rod mounted on the top of the two fixed seats, and the output end of the first electric push rod is fixedly connected to a clamping block.

[0008] As a further embodiment of the present invention: the conveying assembly includes two conveying rollers rotatably connected to the inner side of each of the conveying frames, a conveyor belt is installed on the outer wall of the two conveying rollers, and the stacked temperature instruments are placed on top of the conveyor belt. At the four corners of each temperature instrument, a stop block for limiting the movement of the temperature instrument is fixedly connected to the top of the conveyor belt. A first drive motor for driving the conveying rollers to rotate is installed on one side of each of the conveying frames.

[0009] As a further embodiment of the present invention: the heating auxiliary component includes a tray fixedly connected between the two conveyor frames, three support seats fixedly connected to the top of the tray, a heating block is provided on the inner side of each support seat, a rotating shaft is fixedly connected to both sides of the heating block, one end of the rotating shaft passes through the outer wall of the support seat and is rotatably connected to the support seat, and a torsion spring is installed between the rotating shaft and the support seat.

[0010] As a further embodiment of the present invention: the heating auxiliary component further includes a second electric push rod installed on the top of the workbench, the output end of the second electric push rod is fixedly connected to a connecting plate, and the top of the connecting plate is fixedly connected to three top rods, one end of each top rod extending through to the top of the tray and located on the back of one of the heating blocks.

[0011] Compared with the prior art, the beneficial effects of the present invention are: By coordinating components such as conveyor belts and employing an intermittent conveyor belt and limit block structure, temperature instruments are transported in batches stably, preventing instrument offset and tipping, thus improving calibration efficiency and continuity. Simultaneously, multiple sets of heating blocks are driven by electric push rods to tightly grip the temperature sensor head, ensuring close contact between the heating surfaces, reducing heat loss through gaps, and achieving uniform and stable temperature transmission, significantly reducing calibration errors. Combined with precise temperature control by PLC and real-time detection by camera, temperature instrument errors are automatically identified and located for calibration, resulting in high detection accuracy and facilitating subsequent marking processes, demonstrating a high degree of overall automation.

[0016] Please see Figures 1-5 This embodiment provides a temperature instrument error calibration device, including: a workbench 1 and two conveyor frames 4 fixedly connected to the top of the workbench 1. Each conveyor frame 4 has a fixed base 2 fixedly connected to one side, and a clamping assembly is provided on the top of the fixed base 2; multiple temperature instruments 3 are stacked on top of the conveyor frames 4, and a conveying assembly for conveying the temperature instruments 3 is provided on the inner side of the conveyor frame 4. A knob 19 is installed on the front end of the temperature instrument 3 and is rotatably connected to the temperature instrument 3. A temperature sensor 11 is installed on the detection part of the temperature instrument 3. A heating auxiliary component for heating the temperature sensor 11 is provided at the bottom of the workbench 1 below the temperature sensor 11. The clamping assembly includes a first electric push rod 9 installed on the top of the two fixed bases 2, and a clamping block 8 is fixedly connected to the output end of the first electric push rod 9. The conveying assembly includes two conveyor rollers 6 rotatably connected to the inner side of each conveyor frame 4, and a conveyor belt 7 is installed on the outer wall of the two conveyor rollers 6. Temperature gauge 3 is placed on top of conveyor belt 7. At the four corners of each temperature gauge 3, a stop block is fixedly connected to limit the movement of the temperature gauge 3. A first drive motor 5 for driving the conveyor roller 6 to rotate is installed on one side of each conveyor frame 4. The heating auxiliary component includes a tray 13 fixedly connected between two conveyor frames 4. Three support seats 20 are fixedly connected to the top of the tray 13. A heating block 14 is provided on the inner side of each support seat 20. A rotating shaft 17 is fixedly connected to both sides of the heating block 14. One end of the rotating shaft 17 passes through the outer wall of the support seat 20 and is rotatably connected to the support seat 20. A torsion spring 18 is installed between the rotating shaft 17 and the support seat 20. The heating auxiliary component also includes a second electric push rod 12 installed on the top of the workbench 1. A connecting plate 15 is fixedly connected to the output end of the second electric push rod 12. Three push rods 16 are fixedly connected to the top of the connecting plate 15. One end of each push rod 16 passes through the top of the tray 13 and is located on the back of one of the heating blocks 14. First, a camera for monitoring is installed at the bottom of the fixed frame 10 above the temperature instrument 3. A heating module for heating is installed inside the heating block 14. The heating temperature is controlled by a PLC controller. When the temperature instrument 3 needs to be calibrated, the temperature instrument 3 is placed on the top of the conveyor belt 7 one by one and limited by the stop block at the top of the conveyor belt 7. Then, the first drive motor 5 is started intermittently by the PLC controller. The output end of the first drive motor 5 drives the conveyor roller 6 to rotate, thereby driving the conveyor belt 7 to move the temperature instrument 3 intermittently to the bottom of the fixed frame 10 below the camera. Then, the second electric push rod 12 is started. The output end of the second electric push rod 12 drives the connecting plate 15 to move upward. Then, the three push rods 16 push one heating block 14 to rotate towards the temperature sensor 11. When the second electric push rod 12 stops moving, the three heating blocks 14 hold the temperature sensor 11 tightly and the inner heating module generates a temperature test to check whether the temperature instrument 3 has an error. When the camera detects an error in temperature gauge 3, it moves to another location to perform re-laser marking or inkjet coding. The four corner blocks at the top of the conveyor belt 7 limit the temperature instrument 3, preventing it from tipping or shifting during transport. Combined with the rotation of the heating blocks to generate calibration and clamp the instrument, the temperature sensor 11 can be precisely positioned within the effective area of ​​the heating block 14. Simultaneously, the second electric push rod 12 drives the top rod 16 to push the three heating blocks 14 to clamp the temperature sensor 11, ensuring full contact between the heating blocks 14 and the temperature sensor 11. This reduces heat transfer gap loss, ensures the stability and uniformity of temperature transfer, significantly reduces calibration errors caused by positional deviations, and thus improves the accuracy of the temperature instrument 3.
