In order to make the first positioning ring 33 more stably placed on the base 31, the thickness of the positioning block 32 is less than or equal to the depth of the positioning groove 311 in the base 31, that is, the positioning block 32 is not protruded when being placed in the positioning groove 311, so as to prevent the positioning block 32 from abutting against the film 5 on the first positioning ring 33.
The positioning block 32 is provided with a positioning frame 321, the positioning frame 321 may be engraved on the positioning block 32, or may be drawn on the positioning block 32, and drawing is generally selected, so that repeated drawing can be eliminated, and product compatibility is improved. The positioning frame 321 defines the position where the small particle assembly 2 is placed on the membrane 5, and the membrane 5 is mainly expanded on the membrane 5 at the position during the membrane 5 expanding process. Meanwhile, when placing the small particle set 2, the location of the placement can be quickly and accurately found according to the positioning frame 321.
The first positioning ring 33 is disposed on the base 31, the first positioning ring 33 is disposed above the positioning slot 311, and the first positioning ring 33 is annular. The membrane 5 covers the first positioning ring 33, and the edge of the membrane 5 is positioned between the inner wall and the outer wall of the first positioning ring 33, so that the material of the membrane 5 is prevented from being wasted, and the influence on the subsequent process operation is reduced. In order to facilitate the first positioning ring 33 to be taken out from the base 31, a ring taking opening 313 is formed in the base 31, and the ring taking opening 313 is a groove in the base 31 and facilitates taking and placing of the first positioning ring 33.
The film 5 is made of transparent material or semitransparent material, and the positioning frame 321 on the lower positioning block 32 can be observed through the film 5 when the small particle sets 2 are attached to the film 5. The material of the film 5 also needs to have high tensile strength, the small particles in the small particle assemblies 2 are bonded by the adhesive, and the small particle assemblies 2 can be separated from each other only by the larger tensile amount of the film 5. Easy-to-observe factors can be considered in the selection of the material of the film 5, namely, the material of the film 5 can be made of a matte material, so that the appearance contrast of the small particles and the film 5 can be increased, and the small particles can be conveniently found from the film 5 clearly by a visual system. Specifically, the material of the film 5 may be one of polyvinyl chloride, polyethylene, and polyester.

The inner diameters of the second positioning upper ring 41 and the second positioning lower ring 42 are larger than the inner diameter of the first positioning ring 33, so that the second positioning assembly 4 can be positioned in the first positioning ring 33, and the membrane 5 on the first positioning ring 33 is clamped by the second positioning upper ring 41 and the second positioning lower ring 42. Because the inner diameter of the second positioning component 4 is larger than that of the first positioning ring 33, the membrane 5 after the material positioning can be fixed by the embedded connection of the second positioning upper ring 41 and the second positioning lower ring 42, which is convenient for the subsequent process operation
A small granule forming and subpackaging method using the positioning device comprises the following steps:
blanking: the block raw materials are cut into a plurality of long strips according with the size, the long strips are bonded by a bonding agent to form a long strip assembly 1, and then the bonded raw materials are cut into pieces to form a small particle assembly 2. The granule assembly 2 is composed of individual granules, and after the granule assembly 2 is dispersed, a granule is a product, for example, a granule is a prism.
Film covering: a film is covered on the first positioning ring 33 by using a film covering device, the film itself has certain viscosity, and the small particle assemblies 2 can be adhered through the viscosity of the film itself. The membrane covers the inner bore of the first positioning ring 33 and the edge of the membrane is on the first positioning ring 33, i.e. the outer edge of the membrane does not exceed the outer edge of the first positioning ring 33, which not only saves membrane material but also avoids the influence on the subsequent process operation.

Because the position of the positioning block 32 in the base 31 is also determined, the same relative position of the first positioning ring 33 and the positioning block 32 can be ensured in the operation process every time, so that the small particle set 2 can be attached to the same position in the first positioning ring 33 every time aiming at the same product
One side of the film on the first positioning ring 33 is close to the base 31, that is, one side of the film on the first positioning ring 33 faces downwards, and the other side of the film is not covered upwards, so that the film can be stretched upwards from the bottom of the first positioning ring 33 in the film expanding process, and the film is prevented from falling off from the first positioning ring 33 in the stretching process. The pellet assembly 2 is then placed on the membrane, with the pellet assembly 2 positioned within the positioning frame 321.
Since the film covered on the first positioning ring 33 is transparent or translucent, the positioning frame 321 drawn on the positioning block 32 can be seen through the film, and then the small particle sets 2 are sequentially attached to the back of the film on the first positioning ring 33 along the positioning frame 321.

The membrane expanding top column 6 moves upwards to the second positioning lower ring 42 to be connected with the second positioning upper ring 41 in a clamping and embedding manner, and the small particle sets 2 are in a dispersed state on the membrane. In the process, the membrane expansion can be carried out in two steps, namely a first membrane expansion stage and a second membrane expansion stage.
A first membrane expanding stage: at the beginning of the membrane expansion, the membrane expansion prop 6 moves upward until the second positioning lower ring 42 comes into contact with the membrane on the first positioning ring 33. The film expanding prop 6 stops moving, and the film expanding prop 6 starts heating to soften the adhesive in the small particle assemblies 2.
And a second membrane expanding stage: after the adhesive is heated for a certain time and softened, the film expanding top column 6 continues to move upwards, the part of the contacted film is upwards supported and stretched, the small particle assemblies 2 on the film are mutually separated along with the stretching of the film, the original mutual adhesion state is changed into a regular dispersion state on the film, and the small particle forming is completed. Meanwhile, the second positioning lower ring 42 is pressed upwards to be connected with the second positioning upper ring 41 in a clamping and embedding manner, and the membrane in the contact part area of the membrane expanding top column 6 is clamped and fixed by the clamped second positioning upper ring 41 and the second positioning lower ring 42 in a stretching state.
Cutting a film: after the film expanding is finished, cutting off the film outside the area of the second positioning assembly 4 in the film expanding machine, taking out the second positioning assembly 4 which is clamped and embedded and has dispersed small particles on the film, and waiting for subpackaging.
Subpackaging: the sub-packaging process in this embodiment is completed on a balance placing machine. The second positioning component 4 carrying dispersed small particles is placed on the left side of the plate placing machine, and the subpackaging receptor plate 8 is placed on the right side. The left camera on the plate placing machine scans all small-particle positions in a traversing manner, and the right camera scans all hole positions on the receptor plate 8 in a traversing manner and records the positions in the system respectively. The high-speed swing arm carries on suction nozzle 7 on the balance machine and sucks the granule on the second locating component 4 according to the order of sequence accuracy fast and put into in proper order downthehole in the receptor dish 8 on right side, accomplish granule partial shipment.
