[0021] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0022] This utility model provides a stamp-type UV dispensing device, which can solve the problems of large dispensing equipment and high scrap rate required in related technologies.

[0023] See Figure 1 As shown, this utility model provides a stamp-type UV dispensing device, which may include: a dispensing device, which includes a driving mechanism 1 and a dispensing head 2. The driving mechanism 1 is used to drive the dispensing head 2 to dispense adhesive. A microstructure stamp 3 is provided at the bottom of the dispensing head 2; a UV lamp 5 is provided above the dispensing head 2. In this embodiment, the dispensing device adopts a commonly used dispensing machine in the industry. By designing the microstructure stamp 3 on the dispensing head 2, the required pattern can be designed on the microstructure stamp 3. After dispensing, the stamp is used to imprint the adhesive, and then UV (ultraviolet) light is used for curing. It does not require the use of large equipment, improves the quality of finished products, and reduces the scrap rate.

[0024] See Figure 2As shown, in some embodiments, an adapter 4 is installed at the lower end of the drive mechanism 1, and the dispensing head 2 is detachably installed on the adapter 4. In this embodiment, by connecting the adapter 4 to the dispensing device and by detachably installing the dispensing head 2, the dispensing head 2 with different patterns of microstructure stamp 3 can be replaced as needed, thus expanding its applicability.

[0025] See Figure 2 As shown, the adapter 4 is further provided with a threaded hole 41 at the bottom, and the upper end of the dispensing head 2 is provided with a matching external thread 21. The dispensing head 2 and the adapter 4 are connected by threads. In this embodiment, by using threads to connect the adapter 4 and the dispensing head 2, installation and removal are convenient, the threaded structure connection is stable, the support surface is large, and it is easy to imprint.

[0026] See Figure 2 As shown, in some embodiments, the bottom of the adapter 4 is provided with a plurality of threaded holes 41. In this embodiment, by providing a plurality of threaded holes 41, a plurality of dispensing heads 2 can be installed at the same time and dispensing and pressing can be performed simultaneously, thereby improving work efficiency.

[0027] See Figure 2 As shown, in some embodiments, the multiple threaded holes 41 are arranged in a straight line. In this embodiment, the multiple dispensing heads 2 can change the position or number on the threaded holes 41 arranged in a straight line, so that there are different distances between each pair of dispensing heads 2, thus making them suitable for products with different needs and having a wider range of applications.

[0028] See Figure 2 As shown, in some embodiments, a rubber plug 42 is provided at the upper end of the threaded hole 41, and a small hole is provided in the center of the rubber plug 42. In this embodiment, when the dispensing head 2 is not installed in the threaded hole 41, the rubber plug 42 plays the role of blocking the glue. After the dispensing head 2 is installed in the threaded hole 41, the rubber plug 42 is located between the threaded hole 41 and the dispensing head 2, which can play a sealing role.

[0029] See Figure 2 As shown, in some embodiments, the upper end of the dispensing head 2 is provided with a connector 22. The diameter of the connector 22 is larger than the diameter of the small hole of the rubber stopper 42. In this embodiment, the connector 22 is inserted into the small hole of the rubber stopper 42, which can compress the rubber stopper 42 to form a sealing structure, thereby further improving the sealing effect.

[0030] See Figure 2 As shown, in some embodiments, the diameter of the connector 22 is smaller than the diameter of the dispensing head 2. In this embodiment, after the connector 22 is inserted into the small hole of the rubber plug 42, since the diameter of the dispensing head 2 is larger, its top surface can abut against the bottom of the rubber plug 42, forming a better sealing structure and further improving the sealing effect.

[0031] See Figure 2 As shown, in some embodiments, a heater 7 is installed inside the adapter 4, and a heating element 6 is provided on the microstructure stamp 3. The heating element 6 is connected to the heater 7. In this embodiment, by using the heating element 6 to heat the microstructure stamp 3, for some products with low requirements, UV adhesive can be omitted for imprinting. Instead, the microstructure stamp 3 can be made of metal and heated to a temperature between 120° and 160°. This hot stamping head can then directly press the PMMA (polymethyl methacrylate) or PC (polycarbonate) layer to form a hot-pressed microstructure on its surface.

[0032] See Figure 2 As shown, in some embodiments, the heating element 6 is disposed on the inner wall of the microstructure stamp 3, and the heat of the heating element 6 is directly conducted to the microstructure stamp 3, resulting in faster heating speed and more uniform heating effect.
