[0064] Inside the main body part of the cabinet, a marble adjusting frame 530 is arranged, a marble 540 is horizontally placed on the marble adjusting frame 530, a high-precision turntable 510 (a single-shaft high-precision turntable is adopted in the utility model, the measurement range is 0-360°, the digital display resolution is 1″, and the graduation accuracy is 6″) is horizontally placed on the plane of the marble 540, a conductive slip ring 520 is installed on a horizontal beam inside the cabinet main body through a slip ring installation plate 111, so as to realize the communication connection between the to-be-measured inclination sensor and the hardware control system, and the back surface of the high-precision turntable 510 is fixed on the same horizontal beam inside the cabinet main body through a bolt locking, so as to prevent the high-precision turntable 510 from being accidentally touched and falling to cause a safety accident.

[0065] The high-precision rotary table 510 has a T-shaped groove mounting disc surface extending out of the front panel of the cabinet, and a tooling assembly is fixed on the mounting disc surface of the high-precision rotary table 510. The tooling assembly is divided into horizontal tooling assembly, vertical tooling assembly and disc tooling assembly according to different installation modes of products. The three tooling assemblies can be switched according to different use scenarios. A plurality of to-be-tested inclination sensors are fixed on the tooling assembly. For example, the inclination product with a housing (single-axis, double-axis, three-axis, etc.) in a horizontal installation mode is suitable for the horizontal tooling assembly. The inclination product with a housing (single-axis, double-axis, three-axis, long-angle, etc.) in a vertical installation mode is suitable for the horizontal vertical tooling assembly. The disc tooling assembly can be compatible with all inclination products with a housing except the product in the vertical installation mode, especially the product (such as an inclination switch) with a circular plastic / metal housing. In addition, the utility model can also debug the bare board product. Only a conversion board assembly for bare board debugging needs to be added to the tooling assembly, and other wiring fixing modes remain unchanged.

[0066] As shown in Figures 6-8 The three tooling assemblies each include a tooling plate and elbow clamps 401 (8 are provided in the utility model, and hardware and software can be expanded as needed), elbow clamp pads 403, wiring terminal tables 402 and 24PIN quick connection terminals 404 respectively installed on the tooling plate. The tooling plate is fixedly connected to the T-shaped groove on the mounting disc surface through a T-shaped nut. The tooling plates of the horizontal tooling assembly, the vertical tooling assembly and the disc tooling assembly correspondingly adopt horizontal square plates, vertical square plates and circular plates respectively. The elbow clamp pads 403 are arranged between the elbow clamps 401 and the tooling plate, and are used for adjusting the installation position of the elbow clamps 401. The elbow clamps 401 are adjusted in cooperation to be compatible with inclination sensor products of different heights. The 24PIN quick connection terminals 404 are used for connecting the rotor wire of the conductive slip ring 520 and the wiring terminal table 402, and can realize the interchange between different tooling assemblies.

The horizontal tooling assembly and the vertical tooling assembly only need to be clamped once to complete the entire debugging process when debugging the single-axis inclination sensor product. For the double-axis inclination sensor product, after debugging one axis, the product needs to be rotated by 90° and clamped again for debugging the other axis. The disc tooling assembly can be compatible with the debugging of single-axis and double-axis products. The single-axis inclination sensor product can complete the entire debugging process by clamping once. The double-axis inclination sensor product needs to rotate the circular plate by 90° after debugging one axis to complete the debugging of the other axis. The disc tooling assembly is provided with a 90° limiting and locking mechanism, so that the circular plate only needs to be rotated by 90° to complete the reversing of the test axis, and the double-axis inclination sensor product does not need to be clamped again in the middle, thereby greatly saving the time consumed for disassembling and assembling the product, and improving the debugging efficiency.

[0087] The servo control board 310: used to communicate with the upper computer, analyze the instructions sent by the upper computer, and generate corresponding instructions to send to the servo motor driver 316;

[0088] The servo motor driver 316: receives the instructions sent by the servo control board 310, analyzes and generates corresponding instructions, and then controls the operation of the high-precision turntable 510;

[0089] The high-precision turntable 510: the tooling assembly is installed on the high-precision turntable 510, and the to-be-debugged tilt angle sensor product is installed on the tooling assembly. When the upper computer controls the operation of the high-precision turntable, it is equivalent to controlling the rotation angle, rotation direction and operation track of the to-be-debugged tilt angle sensor product. That is, the output data of the to-be-debugged tilt angle sensor product will change with the change of the high-precision turntable 510, and the most important step in the automatic debugging process of the to-be-debugged tilt angle sensor product is to send different debugging instructions to the product when the to-be-debugged tilt angle sensor product is at different angles. The realization of this process depends on the operation of the high-precision turntable 510.

[0090] Angle digital display table 202: the angle digital display table 202 reads the current rotated angle of the high-precision rotary table 510 at any time, and carries out data interaction with the upper computer; the upper computer compares the rotated angle of the rotary table sent by the angle digital display table 202 with the target angle buffered in the upper computer, and then dynamically and real-timely adjusts the operation parameters of the high-precision rotary table 510, such as the operation direction (clockwise or counterclockwise) and the operation speed (the rotated angle of the rotary table is closer to the target angle, and the operation speed is smaller), so that the high-precision rotary table 510 is accurately controlled to the target angle in the optimal mode;

[0091] Industrial network switch 303: used for assembling the internal local area network of the automatic debugging device, so that the functional modules in the whole device are connected in the same local area network, and the upper computer can uniformly schedule the functional modules;

[0094] Serial port server: the utility model adopts an RS232 / RS485 / RS422 serial port server 304, which is a multi-channel data conversion module; the main function of the serial port server is to convert the data sent by the system interface conversion board into network data of a corresponding format, and sends the data to the upper computer through the network interface of the industrial network switch 303; meanwhile, the serial port server also converts the data sent by the upper computer into data that can be parsed by the system interface conversion board, and forwards the data to the system interface conversion board;

[0095] The first network relay control board 308 can control power supply of other modules, and can collect switch signals output by the to-be-tested tilt sensor product and send to the upper computer. In addition, one end of the module communicates with the analog quantity collector 306 through RS485 with stronger anti-interference capability, so as to convert the received data packet into network signals and send to the upper computer. The other end of the module communicates with the upper computer through the industrial network switch 303, converts the relevant data sent by the upper computer into RS485 signals, and then sends to the analog quantity collector 306.

[0096] The second network relay control board 309 can be controlled by the upper computer through the network interface of the industrial network switch 303.

[0100] As shown in the figure, the operation process of the operator when using the automatic debugging device to debug the tilt product in batches is as follows: Figure 12

[0101] 1) Device startup: start the automatic upper computer in the upper computer and log in, load the product debugging file corresponding to the to-be-tested tilt sensor product after initialization, and automatically complete the connection of the upper computer and each functional module, including the relay control module (the first network relay control board 308 and the second network relay control board 309), the serial port server (RS232 / RS485 / RS422 serial port server 304), the digital quantity communication related module (the analog quantity collector 306), the digital quantity communication related module (the first system interface conversion board 301 and the second system interface conversion board 302), the turntable control related module (the servo control board 310 and the servo motor driver 316). The product debugging file contains parameters related to data analysis method of the to-be-tested tilt sensor product, parameter information of each functional module and corresponding debugging step information.

[0102] ​2) Enter information: After the connection of each functional module is normal, the product number, device address, customer SN code and other information of multiple angle sensor products to be debugged are entered into the upper computer through scanning a two-dimensional code or manual input;

[0103] 3) Install the product: according to the model of the angle sensor to be debugged, select the corresponding tool assembly, install the angle sensor to be debugged on the tool assembly and connect the power supply line and signal line, for example, single-axis angle sensor products and angle switch products can use horizontal tool assemblies or vertical tool assemblies, and double-axis angle sensor products can use disc tool assemblies;

[0104] 4) Start automatic debugging: after confirming that the power supply and communication are normal, start the automatic debugging function of the automatic upper computer, and the upper computer controls the entire automatic debugging device and the angle sensor product to be tested according to the step information in the product debugging configuration file, including command transmission and parameter configuration, and in the case of controlling the operation of the high-precision turntable, the product is sent with debugging and calibration related instructions in a timely manner, and the debugging content includes shaft zero correction, accuracy correction and accuracy verification;

[0105] Generally, the debugging process of the angle sensor product to be tested does not require human intervention, but in some special cases, the system will remind the user to intervene by issuing a beeping sound and flashing an indicator light, such as poor communication of the angle sensor product to be debugged, data errors, and the need for reversing operation of the product to be debugged.

[0106] 5) Automatic debugging ends: when the upper computer completes all the debugging steps according to the related parameters of the product debugging configuration file, the automatic debugging process ends; after the automatic debugging process of the angle sensor product to be tested ends, the upper computer automatically uploads the product debugging test result data, i.e. the debugging index data to the remote server, and at the same time uploads the product parameter backup data, the debugging process prompt data file and the product communication file in the debugging process to the remote server; finally, the automatic upper computer is closed, the power of the upper computer and the entire automatic debugging device is turned off, and the automatic debugging of the angle sensor product to be tested of the current batch and model is completed.

[0107] For the above product debugging and calibration process, if all the production staff needs to manually operate according to the debugging guide, not only the time is very large, but also the error probability is very large, and at the same time only one product can be debugged and calibrated, the production efficiency is low, the use of the automatic debugging device for product debugging and calibration greatly improves the production efficiency, and reduces the occurrence of errors caused by human intervention, and the production staff only needs to perform the following operations:

[0108] 1) Install the horizontal tool assembly to the high-precision turntable;

[0109] 2) Load the product's debugging file to the host computer;

[0110] 3) Scan the product number of the 8 products to be debugged;

[0111] 4) Install the 8 products to be debugged on the horizontal tooling assembly;

[0112] 5) Click "automatic debugging" on the host computer;

[0113] 6) After the automatic debugging is completed, check the completeness and correctness of the data;

[0114] 7) Remove the products that have been debugged from the tooling assembly and properly store them.
