[0026] When slight shaking occurs during the transferring of the suspension assembly, the buffer plate 717 is always in contact with the limiting blocks on the two limiting buffer rods 715 due to the absorption of the force generated by the shaking by the buffer spring 718 and the anti-back-off ratchet plate 730, so that the suspension assembly is basically in a stable state during the entire transferring process. When the suspension assembly is transferred to the uppermost part of the placement table 11 and stops transferring, inertia is generated on the suspension assembly, and the buffer plate 717 is moved along the limiting buffer rod 715 by overcoming the action of the buffer spring 718. In this process, the inertia force is completely absorbed by the continuous compression of the buffer spring 718, and after the absorption, the buffer plate 717 is not pushed by the force instantaneously released by the buffer spring 718 due to the blocking of the two anti-back-off ratchet plates 730, thereby avoiding causing greater shaking. In this process, the buffer ratchet plate 714 and the anti-back-off ratchet plate 730 are interconnected and combined by the gravity of the suspension assembly itself, and the inertia force generated at the moment of stopping the conveying is absorbed by the buffer spring 718, and after the inertia force is eliminated, the buffer plate 717 is not pushed by the force instantaneously released by the buffer spring 718 due to the blocking of the two anti-back-off ratchet plates 730, thereby avoiding causing greater shaking. Thus, the risk of suspension falling due to severe shaking is avoided, and the safety hazard is reduced. When the suspension assembly is placed on the placement table 11, the sliding plate 703 rises due to the lack of the influence of its gravity, so that the buffer plate 717 leaves the two anti-back-off ratchet plates 730, and is reset under the action of the buffer spring 718, thereby ensuring the subsequent work.

[0027] With reference to Figure 1 , Figure 6 and Figure 7 , in a preferred embodiment, the positioning assembly 9 comprises: the partition plates 905, two partition plates 905 are fixedly connected to the upper side of the workbench 1 away from the conveying roller 2 at equal intervals; the alarm 901, which is arranged on the outer wall of one of the partition plates 905.

[0029] When the installation of the suspension assembly is completed, the installation table 15 and the suspension assembly are then conveyed along the grooved track 3 by the conveying roller 2 to above the positioning table 902, the positioning table 902 is lowered under the gravity of the installation table 15 and the suspension assembly, overcoming the action of the plurality of extension springs 906, while the plurality of hammers 904 follow it and press the corresponding pressure sensors 903, in the process, if the data of the plurality of pressure sensors 903 are different, the control panel 5 receives the model and feeds back to the alarm 901 to alarm the staff to check whether the jam occurs, and the data of the pressure sensor 903 can be detected to determine whether the total weight of the suspension assembly is the same as the actual product weight, so as to avoid the product quality decline caused by installation omission, and the positioning table 902 and the installation table 15 are limited by the two partitions 905, preventing the suspension assembly from deviating in the subsequent lifting process, and improving the work efficiency.
