DETAILED DESCRIPTION

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0028] Embodiment 1

[0029] Reference Figure 1-Figure 5 As shown, a laser curing device of the utility model comprises:

[0030] A laser light source module 1, the laser light source module 1 is connected to a plurality of optical fibers 11;

[0031] The light source output module 2 includes a coaxially connected housing 21 and a base 22. A plurality of fixing holes 211 are provided at one end of the housing 21 close to the base 22. A ferrule 212 is coaxially arranged in each fixing hole 211. The optical fiber 11 is respectively inserted into one ferrule 212. A through hole 221 corresponding to the position of the ferrule 212 is provided on the base 22. A scattering sheet 23 is coaxially arranged at one end of the base 22 away from the housing 21. A plurality of photosensors 24 are arranged between the scattering sheet 23 and the base 22.

[0032] The driving module 3 is connected to the laser light source module 1 and the photosensitive sensor 24 respectively.

[0033] Specifically, the laser light source module 1 provides a light beam with a stable wavelength for the light source output module 2 through the optical fiber 11; the core 212 is arranged in the shell 21 and one end of the core 212 is coaxially bonded to each fixing hole 211 by inorganic glue, and each core 212 is provided with a central hole for the output end of the optical fiber 11 to pass through, and the optical fiber 11 is stably fixed on each core 212, and the light beam emitted from the output end of the optical fiber 11 can pass through the scattering plate 23 provided on the base 22 and irradiate the product that needs to be cured and dried; at the same time, the photosensitive sensor 24 located between the scattering plate 23 and the base 22 can detect the intensity of the scattered light of the reflected light and the emitted light on the scattering plate 23 in real time, and transmit the real-time detection data to the driving module 3, and the driving module 3 can monitor and feedback the working status of the laser light source module 1 and each optical fiber 11 based on these data, and at the same time, the driving module 3 can power the laser light source module.

[0034] The utility model provides a laser curing device, which adopts laser as a light source, can provide a light beam with a stable wavelength and light energy with a higher intensity, and is provided with a light source output module 2 with a unique structure, which can well fix and distribute a single or multiple optical fibers connected to the laser light source module 1, and can produce a light beam with a higher collimation effect and better uniformity in cooperation with a scattering plate 23, and has a higher curing efficiency. At the same time, a photosensor 24 is also provided, which can provide real-time feedback on the working status of the light source output module 2 and each optical fiber 11, and can ensure the stable operation of the entire curing device.

[0035] Reference Figure 3 , Figure 4 and Figure 5 As shown, further, the shell 21 is a cylindrical structure with an open end, and a top cover 25 is coaxially arranged at the open end of the shell 21 to form an internal cavity, and a cylindrical protrusion is coaxially arranged at the end of the shell 21 away from the top cover 25, and a plurality of fixing holes 211 connecting the cavity are opened on the protrusion, and the core 212 is coaxially connected to each fixing hole 211 by an adhesive.

[0036] Furthermore, a plurality of fixing holes 211 are arranged on the protrusion in a linear, matrix or circumferential manner. Specifically, the arrangement of the fixing holes 211 can be set according to actual use requirements to meet different use scenarios. More preferably, the housing 21 can be set as a split structure, specifically, the protrusion is set as a detachable structure, for example, a threaded hole that can be threadedly connected to the protrusion is set on the housing 21, so that different protrusions can be replaced according to different use requirements (the arrangement of the fixing holes 211 on the protrusion is different).

[0037] Furthermore, the diameter of the through hole 221 matches the diameter of the protrusion, and the base 22 is coaxially sleeved on the protrusion through the through hole 221 and connected to the housing 21. The protrusion cooperates with the through hole 221, which can facilitate the installation of the entire light source output module 2, and also further reduce the volume of the device, which can improve the applicable scenarios of the curing device to a certain extent.

[0038] Furthermore, the top cover 25 is provided with a through hole for the optical fiber to pass through.

[0039] Furthermore, two connecting ears are symmetrically arranged on the side surface of the top cover 25, and connecting holes are formed on both connecting ears.

It can be imagined that the scattering sheet 23 can not only make the light beam more uniform, but also can be used as an isolating member to protect the photosensitive sensor 24 and the optical fiber 11, so as to prevent the emission end of the photosensitive sensor 24 and the optical fiber 11 from being contaminated, and to a certain extent, the service life of the optical fiber 11 and the photosensitive sensor 24 can be improved.

[0041] Furthermore, the circuit board 26 includes an annular main body 261, and an annular groove 222 corresponding to the main body 261 is provided at one end of the base 22 away from the housing 21. The main body 261 is embedded in the annular groove 222 and is coaxial with the through hole 221, and a plurality of photosensitive sensors 24 are connected to the main body 261. It can be imagined that the annular main body 261 not only prevents the circuit board 26 from interfering with the light beam emitted by the optical fiber 11, but also enables the photosensitive sensors 24 to be evenly arranged along the main body 261, which is conducive to the photosensitive sensors 24 to monitor the power at different positions.

[0042] Furthermore, a strip-shaped connecting portion 262 is vertically extended from the side of the main body portion 261, and a through groove 223 matching the shape of the connecting portion 262 is provided at one end of the base 22 away from the housing 21, and the connecting portion 262 is embedded in the through groove and connected to the driving module 3. Specifically, a receiving groove matching the shape and size of the scattering sheet 23 is provided on the bottom surface of the base 22, and the position of the scattering sheet 23 can be limited by the receiving groove to ensure the stability of the scattering sheet 23; the above-mentioned annular groove 222 and through groove 223 are provided on the bottom surface of the receiving groove, which can fix the circuit board 26 and also make the structure of the entire light source output module 2 more compact.

It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
