Working principle: (1) A workbench is provided in the middle of the top of the base, and a plurality of vertically extending first through holes are provided on the workbench. A mounting hole extending vertically and arranged on the base is provided below the first through hole. A guide column spring and a guide column are provided inside the mounting hole. The guide column spring is arranged below the guide column, and the top end of the guide column passes through the first through hole upward. Thus, the product back cover can be placed on the top of the base and the workbench. At this time, under the elastic action of the guide column spring, the top end of the guide column passes through the first through hole and the third through hole 1201 of the product back cover in turn upward and enters the sliding groove of the product back cover. Then, one end of the product spring is inserted into the buckle of the product back cover, and the other end of the product spring is inserted into the top end of the guide column. (2) A limit table fixed to the top of the workbench is provided on one side of the first through hole. The elastic force of the guide column spring can make the top end of the guide column higher than the limit table. Thus, when the slider is placed downward into the sliding groove of the product back cover, the mounting column on the slider moves downward. Corresponding to the top of the guide column, the slider is pressed down at the same time, and the downward pressure of the slider causes the guide column to move downward, while the limit table can prevent the end of the product spring inserted into the guide column from also moving downward; (3) a second through hole is provided through the side wall of the first through hole, and a guide column positioning groove is provided on the side wall of the guide column. A plurality of drive blocks are provided on the top edge of the base, and a positioning column is provided on the side of the drive block close to the workbench. The positioning columns of the plurality of drive blocks are respectively inserted into the plurality of second through holes, and the positioning columns and the guide column positioning grooves can achieve positioning and disengagement; thus, when the guide column is pressed down to a certain extent, the guide column positioning groove of the guide column and the positioning column of the drive block achieve positioning and disengagement. At this time, the guide column is pressed down into place, and the installation column on the slider completes the insertion of the end of the product spring originally inserted into the guide column. At the same time, the slider is installed in place in the sliding groove of the product back cover, and then the product cover is covered on the top of the product back cover and the slider, and the driving end of the slider is exposed upward through the cover opening of the product cover.In this way, the front and rear, upper and lower limits of the slider are completed, so that the slider can only move left and right in the sliding groove, and the main function of the product spring is to provide power for the slider to reset. (4) Remove the assembled vehicle-mounted product, disengage the positioning column and the guide column positioning groove, and the guide column resets upward under the elastic force of the guide column spring, thereby completing a cycle of product spring assembly. From the above analysis, it can be seen that the technical effects obtained by the present invention are as follows: through the low-cost simple mechanical structure design, this spring installation device is independently developed to eliminate the problems of missing installation, wrong installation, inadequate assembly, inconsistency, etc. caused by blind installation of the spring; the spring installation has the engineering characteristics of process consistency, stable working hours, high product yield and high quality.
