[0002] With the widespread adoption of electric vehicles, demand for high-precision inertial navigation products is increasing, making quality control and product performance stability particularly important for autonomous driving. During the assembly and testing of high-precision intelligent navigation systems, rubber cushions are essential to reduce the impact of vibration stress on measurement accuracy. This also allows for testing and data traceability of press-fit testing equipment.

[0003] There are two main types of intelligent manufacturing, pressing and testing for traditional inertial navigation products: one is to assemble the PCBA and rubber pads to the housing, press them with a manual press, and configure the rubber pad profiling head on the jig; the other is to add it during the product inspection process.

[0004] Traditional inertial navigation product assembly and testing methods rely on press-fitting and testing equipment, which poses certain quality risks and renders data traceable throughout the entire testing process. Therefore, the ability to innovatively design automated inertial navigation product testing equipment and data traceability is crucial. Utility Model Content

[0033] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] Reference Figure 1 and Figure 2 The following is a schematic diagram of the automatic driving inertial navigation product press-fit detection device and its application. The specific structure is as follows:

[0035] On the inspection table 9, a servo dividing plate 1 with a fixed rotating shaft is set. The servo dividing plate 1 can be driven to rotate along its rotating shaft. A number of placement positions for inspected products (4 in this embodiment) are set on the disk surface of the servo dividing plate 1. These placement positions for inspected products are on a concentric circle relative to the rotating shaft of the servo dividing plate.

[0036] Correspondingly, several (4 in this embodiment) workstations for performing related operations are set on the disk surface of the servo dividing disk 1. As shown in the figure, the ST1 workstation is used to remove the inspected product and replace it with the new inspected product at the inspection zero position. A barcode scanning device (such as an automatic barcode scanning gun) is set at the ST1 workstation for identifying the identification code of the inspected product (such as the SN code such as the product traceability code); at the ST2 workstation, a CCD detector (such as a CCD camera) is installed to detect whether the shock-absorbing rubber pads (usually 4 shock-absorbing rubber pads) of the inspected product are missing; at the ST3 workstation, a pressure sensor 4 driven by a first servo motor 6 is set. The first servo motor 6 drives the pressure sensor 4 to press down, acting on the shock-absorbing rubber pad of the product, and applying the set pressure to the rubber pad. The pressure detection is used to detect whether the rubber pad is assembled (for example, whether the rubber pad is flattened after installation); at the ST4 workstation, the second servo motor 7 drives the displacement sensor 5 to detect whether the four shock-absorbing rubber pads have horizontal displacement and the amount of displacement.

[0037] The product placed on each inspected product placement position on the servo indexing plate 1 is driven by the rotation of the servo indexing plate, passing through the zero position (ST1 position), ST2 position, ST3 position and ST4 position in sequence, and then returning to ST1 position. After the relevant inspection items are completed, a new inspected product is loaded on the inspected product placement position.

[0038] Of course, in order to ensure the matching of the detection, the distance between each detection station and the servo indexing disk rotation axis is consistent with the radius of the concentric circle where each inspected product is placed.

[0039] In this embodiment, four workstations are arranged at 90-degree intervals on a circle.

[0040] Furthermore, it can also be matched with a host computer and a PLC control system for information interaction and command execution. As shown in the figure, a start button 8 is also provided on the test platform 9, which further increases the degree of automation of the entire device.

[0041] That is, the working principle of the inertial navigation product assembly and detection device of the present invention is as follows: the product is placed in the ST1 station: the automatic scanning of the product is started to scan the SN code for product traceability; at the ST2 station, the CCD is used to detect whether the 4 shock-absorbing rubber pads are missing; at the ST3 station, the pressure is detected and the servo motor drives it back to its position after the set pressure holding time is completed; and the displacement of the rubber pad is detected at the ST4 station. This realizes the automatic detection process steps of automatic code scanning-CCD detection of whether the rubber pad is missing-pressure and time-displacement detection. Among them, the pressure sensor of the ST3 station and the displacement sensor of the ST4 station can be calibrated regularly, and the pressing time is timed by the PLC. The working principle of the downward pressure holding is: the servo automatically presses down to the set servo upper limit stroke, the pressure starts to detect the set pressure, and when the pressure is reached, the servo stops pressing down, the PLC counts, and when the set time is reached, the servo rises to a safe position and waits for the next product.
