Optionally, the screen printing plate 20 is of a gauze structure; the ink is black ink so that the marking effect of the marking point 50 is more obvious.

The scanning device recognizes the position of each marking point 50 by the light reflecting portion 52 of each marking point 50.

In order to ensure the relative fixing effect between each mark point 50 and the corresponding guard point 31, an adhesive layer is disposed at the ink dyeing part 51 of each mark point 50, so that each mark point 50 and the corresponding guard point 31 are adhered by the adhesive layer. Specifically, each of the marking points 50 is provided with an adhesive layer at the ink-staining portion 51 on the side facing the corresponding guard point 31.

In a specific implementation process, after the screen printing plate 20 is removed from the reflective plate 10, painting an adhesive on the ink dyeing part 51 of each mark point 50 to form an adhesive layer on the ink dyeing part 51 of each mark point 50; the application of the adhesive should be avoided during the application of the adhesive to the retroreflective portions 52 of the respective marking points 50.

Alternatively, the adhesive applied to the dye portion 51 of each marking point 50 is a liquid glue.

Specifically, the reflective sheet 10 is a reflective tape; the reflective layer is made of granular powder, and the light bottom layer 12 is light bottom paper; the protective sheet 30 is glassine base paper, which has a characteristic of being easily separated from glue.

Specifically, each cutter ring 42 is annular, and the diameter of each cutter ring 42 is equal to the outer diameter of the corresponding mark point 50; i.e., the diameter of each cutter ring 42 is equal to the outer diameter of the inking part 51 of the corresponding index point 50.

Optionally, the substrate 41 is a wood substrate.

In this embodiment, the mark point forming assembly further includes a first transfer film 60, and after the guard points 31 are formed, the first transfer film 60 is disposed on the side of the guard points 31 far from the mark points 50, so that each guard point 31 is attached to the first transfer film 60; the base layer 12, the first transfer film 60, and the plurality of indicia 50 and the plurality of guard dots 31 positioned between the base layer 12 and the first transfer film 60 together form the indicia carrier assembly 90.

In this embodiment, the mark forming assembly further includes a second transfer film 70, after the light base layer 12 is detached from the plurality of mark points 50, the second transfer film 70 is disposed on a side of the mark points 50 away from the first transfer film 60, so that the plurality of mark points 50 are attached to the second transfer film 70; that is, a plurality of marking points 50 are arranged on the second transfer film 70 in the above-described predetermined pattern.

In this embodiment, the marking point forming assembly further includes a transparent plate 80, and a side of the plurality of marking points 50, which is away from the second transfer film 70, is adhered to the transparent plate 80 after the first transfer film 60 and each of the shielding points 31 are detached from the corresponding marking point 50.

Since the first adhesive layer is disposed on the side of the reflective layer of the reflective plate 10 facing the bottom layer 12, the reflective layer of the reflective plate 10 and the bottom layer 12 are adhered by the first adhesive layer, i.e., the plurality of mark points 50 are partially adhered to the bottom layer 12 by the first adhesive layer at each mark point 50. Since the adhesive layer is not disposed on the optical substrate 12, that is, the optical substrate 12 itself has no adhesive property, in order to adhere the plurality of marking points 50 of the plurality of marking points 50 to the transparent plate 80 in the form of the predetermined pattern, the second adhesive layer is disposed on the side of the second transfer film 70 adjacent to the plurality of marking points 50, such that, after the plurality of marking points 50 are attached to the second transfer film 70 in the form of the predetermined pattern, the side of the second transfer film 70 having the plurality of marking points 50 is attached to the transparent plate 80 through the second adhesive layer thereof, wherein the plurality of marking points 50 are located between the second transfer film 70 and the transparent plate 80, and at this time, the side of the plurality of marking points 50 away from the second transfer film 70 is adhered to the transparent plate 80; then, the second transfer film 70 is detached from the transparent plate 80, and the plurality of marking points 50 are retained on the transparent plate 80 in the predetermined pattern.

It should be noted that the mark points 50 have a scanning surface and a connecting surface, that is, when the ink penetrates into the reflective layer, the ink penetrates from the scanning surface of each mark point 50 to the connecting surface; each marker dot 50 is connected to the photobase layer 12 by its connecting surface; each index point 50 is connected to the second transfer film 70 through a connection surface thereof; when the plurality of marking points 50 reside on the transparent plate 80, the scanning surface of each marking point 50 faces the transparent plate 80.

Optionally, the first adhesive layer is made of pressure-sensitive adhesive (i.e., pressure-sensitive adhesive); the second adhesive layer is made of pressure-sensitive adhesive.

Alternatively, the first transfer film 60 and the second transfer film 70 are both PVC films.

In practical use, the surface of the bottom layer 12 of the retroreflective sheeting 10 is covered with a smooth film, which results in poor adhesion between the bottom layer 12 and the plurality of marking points 50; since the adhesive coated on the ink-dyed portion 51 of each of the plurality of mark points 50 is a liquid adhesive having a viscosity greater than that of the pressure-sensitive adhesive, the plurality of mark points 50 can be adhered to the transparent plate 80 after the second transfer film 70 is detached from the transparent plate 80.

Specifically, the transparent plate 80 has a light transmittance of 92% or more. Optionally, the transparent plate 80 is a glass plate; preferably, the transparent plate 80 is an ultra-white glass plate.

The invention also provides a marking point forming method, as shown in fig. 6, the marking point forming method comprises the following steps: step S10, forming a plurality of mark points 50 on the reflective layer of the reflective sheet 10; in step S20, the retroreflective layer is cut by the cutting member 40 to obtain a plurality of marking points 50.

Wherein the step S10 of "forming a plurality of marking dots 50" is to form a plurality of marking dot patterns on the retroreflective layer, and the plurality of marking dots 50 are connected together by the rest of the retroreflective layer; the step S20 "obtaining a plurality of mark points 50" is that after the plurality of mark point patterns are formed and the retroreflective layer is cut by the cutting member 40, the plurality of mark points 50 are all distributed on the retroreflective layer 12 of the retroreflective sheeting 10 independently of each other.

In step S10, the method of forming a plurality of marker points 50 includes: step S11, superimposing the silk screen plate 20 having the plurality of penetration portions 211 on the reflective layer of the reflective sheet 10; step S12, the screen printing plate 20 is painted with ink so that the ink permeates the reflective layer through the plurality of permeating portions 211 to form a plurality of mark points 50 on the reflective layer of the reflective sheet 10.

After forming the plurality of mark points 50 on the reflective layer of the reflective sheet 10, the mark point forming method further includes: step S30, covering the protective plate 30 on the side of the reflective layer far away from the light bottom layer 12 of the reflective plate 10; step S40, arranging the cutting component 40 on the side of the protective plate 30 far away from the reflective layer, and enabling the cutter rings 42 of the cutting component 40 to correspond to the mark points 50 one by one; in step S50, the cutting member 40 is moved toward the masking sheet 30 to cut out the plurality of marking points 50 and the plurality of masking points 31 attached to the corresponding marking points 50.

Specifically, in step S30, before the protective sheet 30 is covered on the side of the reflective layer away from the bottom layer 12 of the reflective sheet 10 and after a plurality of mark points 50 are formed on the reflective layer of the reflective sheet 10, the screen printing plate 20 is removed from the reflective sheet 10 and the adhesive is applied at the inked portions 51 of the respective mark points 50 to form an adhesive layer on the inked portions 51 of the respective mark points 50.

Specifically, the base plate 41 is used to be fixed on the blanking apparatus to drive the base plate 41 toward the sheathing plate 30 by a driving mechanism of the blanking apparatus.

The marking point forming method further comprises the following steps: step S60, after cutting the plurality of mark points 50 and the plurality of guard points 31, removing the remaining portions of the reflective layer except the plurality of mark points 50 and the remaining portions of the guard plate 30 except the plurality of guard points 31; step S70, the first transfer film 60 is overlaid on the side of the plurality of guard dots 31 away from the plurality of marker dots 50 to form the marker dot carrier assembly 90.

After forming the marker dot carrier assembly 90, the marker dot forming method further comprises: step S80, detaching the light base layer 12 of the reflective sheet 10 from the plurality of marked points 50; in step S90, the second transfer film 70 is overlaid on the side of the plurality of marker points 50 away from the first transfer film 60.

After the second transfer film 70 is coated on the side of the plurality of index dots 50 away from the first transfer film 60, the index dot forming method further includes: in step S100, the first transfer film 60 is detached from the second transfer film 70 to remove each guard point 31 from the corresponding marking point 50.

After each guard point 31 is removed from the corresponding marker point 50, the marker point forming method further comprises: step S110 of adhering one side of the plurality of marker points 50, which is far from the second transfer film 70, to the transparent plate 80; in step S120, the second transfer film 70 is detached from the transparent plate 80 to retain the plurality of marking points 50 on the transparent plate 80.

From the above description, it can be seen that the above-described embodiments of the present invention achieve the following technical effects:

in the mark point forming assembly of the present invention, it includes the silk screen plate 20 and the cutting means 40 with multiple infiltration parts 211, the multiple infiltration parts 211 on the silk screen plate 20 are arranged in the form of the predetermined figure, the silk screen plate 20 is used for superposing with the reflective layer of the reflective board 10, so as to make the ink infiltrate into the reflective layer of the reflective board 10 through the infiltration parts 211 by painting the ink on the silk screen plate 20, thus make the infiltrated part on the reflective layer form multiple mark points 50; the cutting member 40 includes a base plate 41 and a plurality of cutter rings 42 provided on the base plate 41, the plurality of cutter rings 42 being provided in one-to-one correspondence with the plurality of index points 50, i.e., the plurality of cutter rings 42 are arranged on the base plate 41 in the form of the above-described predetermined pattern; each cutter ring 42 is matched with the corresponding mark point 50, and the cutting part 40 and the reflective board 10 are arranged in a relative motion way, so that when the cutting part 40 moves towards the reflective board 10, the corresponding mark points 50 on the reflective layer can be cut through the cutter rings 42 of the cutting part 40, and the plurality of mark points 50 are arranged on the light bottom layer 12 in a preset pattern; compared with the prior art, the marking point forming assembly can not only accurately measure the object to be measured so as to improve the accuracy of the established model, but also improve the forming efficiency of the marking points by manually pasting the marking points one by one; therefore, the marking point forming assembly can solve the problem that the marking point forming efficiency of the marking point forming method in the prior art is low.
