( And (3) injection: there is the clearance between spacing rail 2 and micro-conveyor 1, avoids spacing rail 2 to influence micro-conveyor 1's operation. )
With continued reference to fig. 3, one side of the micro conveyor belt 1 is provided with a dragging structure 3, the dragging structure 3 is fixed on a frame body of the micro conveyor belt 1 through a bolt, and referring to fig. 4, an assembly schematic diagram of the dragging structure 3 is shown, it can be seen from the figure that the dragging structure 3 comprises a groove body 301, the groove body 301 extends along the length direction of the limit rail 2, a screw shaft 302 is arranged in the groove body 301, and two ends of the screw shaft 302 extend along the length direction of the groove body 301 and are rotationally connected with the groove body 301; a motor is arranged on the groove body 301, an output shaft of the motor is connected with the screw shaft 302, and the motor outputs power for driving the screw shaft 302 to rotate; the sliding body 303 is connected in a sliding way in the groove body 301, a screw hole is formed in the sliding body 303, and the screw hole and the screw shaft 302 are matched; the side of the groove 301, which is close to the limit rail 2, is provided with a slideway, and the left side surface of the sliding body 303 is provided with an adsorbent (for example, the adsorbent can directly adopt a magnetic strip 304, the magnetic strip 304 and the magnet 18 in the limit rail 2 form opposite attraction effect), and the adsorbent can drag the magnet 18 to a position vertically aligned with the upper spring plate 17 by utilizing the attraction force generated between the adsorbent and the magnet 18.
Principle of operation of the drag structure 3: firstly, the magnet 18 after dispensing is transported to the tail end close to the dragging structure 3 by means of the micro-conveyor belt 1 so that the dragging structure 3 adsorbs the magnet 18, and the initial transportation of the magnet 18 is realized; then, the magnet 18 can be transported for the second time by means of the dragging structure 3, so that the magnet 18 moves below the corresponding part of the upper spring plate 17, and the subsequent magnet 18 and the upper spring plate 17 are convenient to align and bond.
Further, during the transportation of the magnets 18 by the micro conveyor belt 1, there may be a case where the magnets slip on the surface of the micro conveyor belt 1, in order to avoid the occurrence of the above-mentioned case; for this reason, in this embodiment, the material of the micro conveyor belt 1 is mixed with a magnetic material, and a magnetic attraction is formed between the magnetic material and the magnet 18; in the present invention, the self magnetism of the magnet 18 is utilized, and no other external force is needed, regardless of the attraction between the magnet 18 and the magnetic stripe 304 or the attraction between the magnet 18 and the magnetic material.

Working principle of the alignment structure 4: firstly, starting a motor 402, wherein the motor 402 drives a ring body 401 to rotate (single rotation of 90 degrees) so that the opening of an alignment groove 5 is opposite to the outlet of a limit rail 2; then, the magnet 18 enters the alignment groove 5 under the drive of the dragging structure 3 until the magnet 18 is in contact with the blocking plate 6; because the position of the closure plate 6 is set in advance, after the magnet 18 contacts with the closure plate 6, the magnet 18 can be positioned at the corresponding position below the upper spring plate 17, so that the subsequent magnet 18 can be accurately adhered to the corresponding position of the upper spring plate 17.
Further, after the magnet 18 enters the alignment groove 5 and contacts the closure plate 6, the adsorbing body for adsorbing the magnet 18 is removed; for this purpose, the invention also installs an electromagnet (model: XDA-65/30; not shown in the figure) on the telescopic cylinder, the magnetic force of the electromagnet to the magnet 18 is larger than the magnetic force of the adsorbent to the magnet 18, when the adsorbent needs to be removed, the electromagnet is started, the electromagnet adsorbs the magnet 18, and the adsorbent is removed.

The magnetic block 8 has the advantages that: firstly, the magnet 8 can stabilize the position of the shell 16 on the upright post 7; secondly, the extrusion force (i.e. adsorption magnetic force) generated between the magnetic block 8 and the upright post 7 and used for extruding the shell 16 and the upper elastic sheet 17 can avoid the situation that the upper elastic sheet 17 falls after the shell 16 is reversely buckled.
At this time, after the shell 16 is fixed, a telescopic cylinder is started, and drives the magnet 18 to move upwards until the glue on the magnet 18 contacts with the upper elastic sheet 17; on one hand, the accurate alignment of the corresponding parts of the magnet 18 and the upper elastic sheet 17 is realized through the telescopic cylinder; on the other hand, after the glue contacts with the upper spring 17, the magnet 18 is driven by the telescopic cylinder to move upwards for a certain distance for more firm adhesion; when the magnet 18 is required to be separated from the alignment groove 5, the electromagnet is powered off.
