It can be understood that N sound magnetic anti-theft tags manufactured in batches can be used independently after being torn from the whole plate.

Example two

In this embodiment, the assembling operation after the alignment of the upper and lower covers is described by taking a snap-fit assembly as an example. In this embodiment, a buckle locking structure is adopted, each hard tag bottom case 11 has a plurality of first buckling members 12, each hard tag upper cover 21 has a plurality of second buckling members 22, and step S3 covers the upper cover plate 2 on the bottom case plate 1, so that each hard tag upper cover 21 and each hard tag bottom case 11 are aligned one by one and assembled into N acoustic magnetic anti-theft hard tags, specifically:

In addition, considering that when the existing acoustic-magnetic anti-theft hard tag is processed, tag parts need to be processed first, and then the tag parts are placed into a shell formed by the upper cover and the lower cover after forming corresponding finished products, for example, a magnetic stripe and a wafer need to be subjected to a film coating process, and then the tag parts are placed into the shell after being sleeved with a film layer, for example, a coil or a lock cylinder needs to be placed into a protective shell, and then the coil or the lock cylinder needs to be placed into the shell formed by the upper cover and the lower cover, which undoubtedly increases the processing flow steps and is not beneficial to the mass production of the product, in the embodiment, the tag parts at least comprise a magnetic stripe without a film, a wafer without a film coating, and a lock cylinder without a film coating; in view of this, as a further improvement, the present embodiment improves the assembly mode of the anti-theft component, and the component assembly mechanism 3 includes a plurality of vacuum chucks arranged in an array to achieve batch and synchronous filling.

and taking N lock cylinders corresponding to the N hard tag bottom shells 11 one by one, and synchronously assembling the N lock cylinders in the lock cylinder accommodating cavities 15 of the N hard tag bottom shells 11.

It should be noted that the above steps may be performed in a sequence or simultaneously, the part assembling mechanism 3 may simultaneously take N wafers, magnetic strips, and lock cylinders for synchronous assembling, or may take the wafers/the magnetic strips/the lock cylinders in different sequences, and sequentially perform assembling, for example, first taking the wafers and assembling in the wafer accommodating cavities, second taking the magnetic strips and assembling in the magnetic strip accommodating cavities, and third taking the lock cylinders and assembling in the lock cylinder accommodating cavities. If it is desired to assemble 2 or more wafers, then repeating the wafer pick-and-place operation can be accomplished.

In addition, at least N suction cups are distributed at the bottom of the component mounting mechanism 3, so that N anti-theft components can be obtained simultaneously, for example, N wafers are sucked by the component mounting mechanism 3 in fig. 6 or fig. 3, and then the N wafers can be placed into the corresponding wafer accommodating cavities 13 simultaneously (the operation can be repeated to place a plurality of wafers, for example, three wafers can be placed by repeating 3 times, that is, K is 3), and automatic alignment is realized simultaneously. The structure replaces the traditional shell to internally place magnetic bar coils or acoustic magnetic soft labels and other finished product anti-theft pieces, the processing flow is simpler and easier, the product cost is further reduced, and the production efficiency is further improved.

Of course, other clamping mechanisms such as magnetic attraction can be selected by the part assembling mechanism 3, and the distribution of the clamping mechanisms is the same as that of the first array, so that N label parts can be obtained simultaneously, a plurality of label parts can be put into corresponding accommodating cavities simultaneously, automatic alignment is realized, and the processing efficiency is greatly improved.

In addition, it should be noted that the magnetic stripe accommodating cavity 14 is located at one side of the wafer accommodating cavity 13, and the key cylinder accommodating cavity 15 is located at the head of the hard tag bottom case 11. The bottom of the upper cover 21 of the hard tag is provided with a first protruding part 23 for covering the opening of the wafer accommodating cavity 13 and a second protruding part 24 for covering the opening of the magnetic stripe accommodating cavity 14, so that the stability of the acoustic magnetic anti-theft hard tag is ensured. Of course, the structure of the housing is only an example, and the shape of the housing may be selected according to the product design requirements of the actual acoustic magnetic anti-theft hard tag, which is not described herein again.
