Please refer to Table 1 for the angle DOE verification data of this embodiment.

In addition, the shape of the front end of the separation rod 121 has a slope surface 122. The design of the slope surface 122 at the front end can guide the separation rod 121 into the interlayer gap 154, and can accurately complete the separation operation of the sandwich structure 150. In addition, the separating rod 121 also has an opening 123 communicating with the interlayer gap 154 to facilitate subsequent dispensing operations.

The angle positioning mechanism 130 is disposed on one side of the carrying platform 110. Please refer to FIG. 5 together. The angle positioning mechanism 130 includes an angle limiting mechanism 132 and a rotation mechanism 135 to drive the bearing platform 110 to rotate so that the included angle of the sandwich structure 150 with respect to the horizontal plane is greater than 0 degrees and less than 90. In other words, the angle positioning mechanism 130 can make the sandwich structure 150 appear inclined (see FIG. 2C), instead of the traditional 90-degree vertical state. In this embodiment, the angle DOE verification shows that the angle positioning mechanism 130 makes the included angle of the sandwich structure 150 relative to the horizontal plane preferably 65 degrees.

After the separation lever 121 separates the sandwich structure 150, the dispensing mechanism 140 can perform the dispensing operation on the sandwich gap 154 through the opening 123 on the separation lever 121. .

In addition, please refer to FIG. 6 together. The sandwich type dispensing apparatus 100 of this embodiment further includes one or more air nozzles 160. The air nozzles 160 are disposed on one side of the loading platform 110 for blowing air toward the sandwich structure 150. .

Referring to FIG. 7, a flowchart of a sandwich dispensing method according to an embodiment of the present invention will be described. The detailed steps are as follows: Step S101, providing the aforementioned sandwich dispensing device 100.

See step S102, placing the sandwich structure 150 on the supporting platform 110.

In step S103, the separation rod 121 is extended into and stretches the interlayer gap 154 between the first flexible substrate 151 and the second flexible substrate 152.

In step S104, the bearing platform 110 is driven to rotate by the angle positioning mechanism 130, so that the included angle of the sandwich structure 150 with respect to the horizontal plane is greater than 0 degrees and less than 90 degrees.

In step S105, the interlayer gap 154 of the interlayer structure 150 is dispensed through the opening 123 by the dispensing mechanism 140.

In step S103, before the interlayer gap 154 between the first flexible substrate 151 and the second flexible substrate 152 is opened by the separating rod 121, the air can be blown toward the sandwich structure 150 through the air nozzle 160 first. Gas for cleaning.

As shown in FIG. 8A and FIG. 8B, it is a schematic diagram showing the dispensing situation of the sandwich type dispensing equipment provided by the embodiment of the present invention. The present invention utilizes the flow characteristics of the glue 11 to expel air from the bottom of the interlayer gap 154, which can avoid the problem of air bubbles caused by the air remaining in the glue 11. As shown in the figure, when dispensing, because the sandwich structure 150 is inclined, the glue 11 will first contact the second flexible substrate 152 on one side of the sandwich structure 150, and then, the glue 11 will flow to the first side of the other side. For a flexible substrate 151, the air in the interlayer gap 154 is pushed out of the interlayer gap 154 by the flow of the glue 11. After the dispensing is completed, since the air in the glue 11 has been exhausted, there is no problem of remaining bubbles.

The invention is particularly suitable for light and thin, sandwich products and machines for high-precision dispensing operations.
