The size of the bottom plate should be sufficient to accommodate the following shock-absorbing device mounting holes. A fixed vertical plate 2, an adjustable vertical plate 3, and shock-absorbing device mounting holes are provided on the bottom plate. The heights of the fixed vertical plate and the adjustable vertical plate should be able to hold the outer contour of the electronic device to form a surface contact positioning.

[0032] The fixed vertical plate is fixedly connected to the bottom plate by screwing. A sliding groove for the adjustable vertical plate to slide is provided on the bottom plate. After the adjustable vertical plate slides along the sliding groove to an appropriate position, it is fixedly connected to the bottom plate by screwing.

One is arranged along the length direction of the bottom plate, and the other is arranged along the width direction of the bottom plate. The adjustable vertical plate is arranged along the width direction of the bottom plate, and the sliding groove is arranged along the length direction of the bottom plate. After the shock-absorbing device 4 and the base 6 are screwed to the bottom plate through the shock-absorbing device mounting holes, a part of the outer edge of the base protrudes out of the bottom plate to facilitate welding after positioning. The position of the shock-absorbing device mounting holes on the bottom plate is determined according to the relative positions of the shock-absorbing device and the base with respect to the fixed vertical plate and the adjustable vertical plate in the final assembly state, that is, the theoretical plane position of the shock-absorbing device when the electronic device is in the final assembly state. The bottom plate, the fixed vertical plate, and the adjustable vertical plate are all aluminum plates.

[0037] Step 3, as Figure 3 shown, place the combined positioning tooling on the assembly platform 7 of the electronic device 5. After the two fixed vertical plates are fitted to the outer contour of the electronic device, then slide the adjustable vertical plate along the sliding groove to make it also fit the outer contour of the electronic device, and then fixedly connect the adjustable vertical plate to the bottom plate by screwing. Through the method of datum transfer, with the aid of the positioning between the combined positioning tooling and the electronic device, the positioning between the shock-absorbing device and the electronic device is completed, ensuring the assembly accuracy of the shock-absorbing device and the electronic device with different dimensional accuracies and geometric tolerances.

[0038] Specifically, the two fixed vertical plates are respectively attached to two adjacent faces on the outer contour of the electronic device, and the adjustable vertical plate is attached to the third face on the outer contour of the electronic device.

[0039] Step 4: After marking the position of the base on the assembly platform, remove the electronic device from the assembly platform. After confirming that the base is in the marked position, perform intermittent welding along the outer contour line of the base to weld the base to the assembly platform.

[0040] Step 5: Remove the combined positioning tooling from the assembly platform and remove the shock-absorbing device from the combined positioning tooling.

[0041] Step 6: After confirming that the base is in the marked position, perform continuous welding along the outer contour line of the base to weld and fix the base to the assembly platform.

[0042] Step 7: As Figure 4 shown, install the shock-absorbing device on the top of the base, and set a gasket between the shock-absorbing device and the base. Adjust the thickness of the gasket to make the shock-absorbing device reach the required height, so that the silicone rubber part on the top of the shock-absorbing device is in contact limit with the electronic device.
