[0026] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings:

[0027] As shown in the figure, an automatic calibration device includes a calibration tool 1 for installing the product to be calibrated, several transfer carts 2 for carrying the calibration tool 1 and the product to be calibrated, a temperature box 4 with a three-axis motion system 3 and an intelligent control system, and a manipulator 5 for grabbing the calibration tool 1 and the product to be calibrated on the transfer cart 2 into the temperature box 4. The lower end of the manipulator 5 is provided with a sliding device 6 for driving it, for example, in a linear direction, such as lateral displacement; this technical solution adopts an intelligent control system, which can achieve precise control of the transfer cart, manipulator, three-axis motion system and temperature box. Through the coordinated work of the above components, the fully automatic integrated three-dimensional calibration equipment can achieve efficient and accurate three-dimensional calibration work. This calibration equipment not only improves the automation level of calibration work and reduces labor costs, but also improves the accuracy and reliability of calibration results, providing strong support for product quality control and performance improvement; the equipment can work in high and low temperature environments, so that it can simulate various extreme environmental conditions for product calibration, thereby ensuring the performance and stability of the product in different environments.

[0028] An example of a calibration product is an inertial module. A temperature chamber is used to simulate calibration scenarios under different temperature environments. By controlling the temperature inside the temperature chamber, the performance of the product to be calibrated can be tested at different temperatures, thereby ensuring that the calibration results have good applicability and accuracy under various environmental conditions.

[0029] Here, the horizontal direction can be understood as referring to the length direction of the incubator, for example.

[0030] Among them, the sliding device can adopt a structure in which a servo motor drives a ball screw pair, or a conveyor belt mechanism combined with a guide rail for auxiliary guidance. There are many devices in the prior art that can achieve lateral sliding, which will not be elaborated here.

[0031] This utility model patent effectively solves the production capacity limitation through a new calibration method, and has unique market prospects and practical value. The intelligent control system serves as the brain of the entire calibration equipment, responsible for coordinating the work of various components, and can achieve precise control of transfer carts, such as AGV carts, six-axis robots, three-axis motion systems and temperature boxes. At the same time, the intelligent control system also has powerful data processing capabilities, and can perform real-time analysis and processing of the data generated during the calibration process, providing accurate calibration results and feedback.

[0032] The three-axis motion system 3 includes:

[0033] A rack 31 is provided in the temperature box 4;

[0034] A turntable 32 is rotatably mounted on the frame 31 and is provided with a plurality of mounting positions 321 arranged along the circumference;

[0035] An X-axis clamp, which is mounted on the frame 31 and has a first transmission assembly at one end thereof that drives it to move along the X-axis direction;

[0036] A Y-axis clamp, which is mounted on the frame 31 and has a second transmission assembly at one end that drives it to move along the Y-axis direction;

[0037] The turntable 32 is provided with a through hole 33 for the Y-axis clamp to pass through at the position of each mounting position 321; a motor (not shown) is provided below the turntable to drive its rotation. The turntable drives the calibration tooling in the mounting position 321 and the product to be calibrated to rotate circumferentially. When the calibration tooling rotates to the position directly above the Y-axis clamping jaw, the Y-axis clamping jaw moves upward under the drive of the second transmission assembly, and continues to move upward smoothly after pushing the calibration tooling. After that, the X-axis clamping jaw moves laterally close to the calibration tooling. The X-axis clamping jaw and the Y-axis clamping jaw work together to achieve the lateral and vertical displacement of the calibration tooling. The multiple mounting positions arranged along the circumference of the turntable allow multiple calibration tools to be installed at the same time, improving the parallel processing capability of the calibration process. In one calibration cycle, multiple products can be calibrated at the same time, and different calibration products can be automatically switched to the working position, which significantly improves the calibration efficiency.

[0038] The Y-axis clamp includes a base 36 and top columns 37 installed at the four corners of the base 36. The upper end of the top column 37 is provided with protrusions 38 corresponding to the four corners of the calibration tooling, which realizes stable clamping of the calibration tooling and prevents calibration errors caused by shaking or displacement of the tooling. The design of the protrusions enables the Y-axis clamp to accurately align and clamp the four corners of the calibration tooling. This precise positioning capability is crucial to ensuring the correct position of the calibration tooling in the temperature chamber, thereby ensuring the accuracy of the calibration results. It should also be known that the design can be modified according to the shape of the tooling to be matched. Through the correspondence between the protrusions and the four corners of the calibration tooling, the Y-axis clamp can quickly and accurately clamp the tooling. This shortens the tooling replacement time during the calibration process and improves the calibration efficiency.

[0039] A magnetic connector 39 for supplying power to the product to be calibrated is installed on the base 36, and a number of positioning seats 11 for guiding and positioning the magnetic connector 39 are provided on the calibration tool 1. After the four protrusions on the base contact the four corners of the calibration tool, the vertical height position of the calibration tool is adjusted, and the magnetic connector is inserted into the product through the positioning seat, and then power is supplied to the product, which improves the automation level of the calibration process and eliminates the need to interrupt the calibration process for power supply operations; this improves calibration efficiency and reduces calibration failures or errors that may be caused by power supply problems.

[0040] The X-axis clamp includes a clamping base 34 and clamping plates 35 installed at both ends of the clamping base 34. The spacing between the clamping plates 35 is adapted to the size of the calibration tooling. The clamping plates can clamp both sides of the calibration tooling. The relative positions of the clamping plates at both ends can be adaptively adjusted according to the size of the tooling. The clamping method is fast and can provide stable support for the calibration tooling, which helps to ensure the stability of the calibration tooling during transportation and reduce calibration errors that may be caused by bumps or vibrations. In addition, since the clamping plates clamp the tooling on the outside, this clamping form can be regarded as a protective clamping to some extent to avoid damage to the tooling during clamping or transportation.

[0041] The clamping seat 34 is equipped with a magnetic connector 39 for supplying power to the product to be calibrated. The calibration tooling 1 is provided with a number of positioning seats 11 for guiding and positioning the magnetic connector 39. When the Y-axis clamp drives the calibration tooling to the same height position as the X-axis clamping seat, the X-axis clamping seat moves laterally and the clamping plate clamps both sides of the calibration tooling. The magnetic connector is just inserted into the product through the positioning seat, and then the product is powered, which improves the automation level of the calibration process and does not require interrupting the calibration process for power supply operations; this improves the calibration efficiency and reduces calibration failures or errors that may be caused by power supply problems.

[0042] Among them, the magnetic connector has the advantages of strong adsorption force and good connection effect through the structural design of magnet-to-magnet contact and attraction.

[0043] The first transmission assembly and the second transmission assembly have the same structure. This standardized design simplifies the manufacturing process of the equipment and reduces production costs. At the same time, the standardized components are also convenient for subsequent maintenance and replacement, and both include a driving member and a transmission rod 8 connected to the output end of the driving member. The transmission rod 8 of the first transmission assembly is arranged horizontally, and the transmission rod 8 of the second transmission assembly is arranged vertically. This layout has a high space utilization rate.

[0044] The driving member adopts a servo motor, and an encoder is provided between the driving member and the transmission rod 8 to connect the two. The high-precision motor and encoder can ensure the accuracy and stability of the movement.

[0045] The transfer vehicle 2 adopts an AGV automatic guided vehicle and adopts advanced navigation and positioning technology, which can ensure the stability and accuracy of the calibration tooling during the movement process, laying a solid foundation for subsequent calibration work.

[0046] The manipulator 5 is a six-axis robot with a sensor 51 installed at its end. The six-axis robot can accurately position and grasp the calibration tooling in three-dimensional space due to its flexible joint design and precise motion control. The end of the six-axis robot is equipped with a high-precision sensor that can detect and feedback the position and posture information of the calibration tooling in real time, ensuring that the calibration tooling, for example, constructed as a cube, is accurately delivered to the incubator.

[0047] The calibration tool 1 adopts a hollow cubic frame. The calibration tool serves as a bridge between the product to be calibrated and the calibration equipment. The tool is made of high-strength aviation aluminum alloy material, which can ensure sufficient strength and precision requirements and is relatively light in weight. At the same time, its structure is compact and easy to install and disassemble; the design of the cubic frame can also enable the calibration tool to be grouped and form a square array, further improving the parallel processing capability of the calibration equipment.

[0048] In summary, this automatic calibration device can be used in scenarios without plugging in at high and low temperature environments.
