The glue needs to be coated on the tape and then completed through multiple processes such as heating, pressing, and cutting. After coating, the tape needs to be dried to solidify the adhesive and make the surface of the tape smooth. In order to ensure the bonding performance of the tape and the quality of the final product, the effectiveness of the curing process is crucial. Traditional tape curing methods mostly rely on natural drying or high-temperature baking, which is not only time-consuming, but also has strict requirements on environmental conditions and is easily affected by humidity and temperature changes. Therefore, how to improve the production efficiency and final quality of the tape is an urgent problem to be solved. Summary of the invention

With the laser drying mechanism, through precise laser irradiation, an efficient curing process is achieved, the curing time is greatly shortened, and production efficiency is improved. After that, through cooling and shaping, the tape can maintain a good shape and size during the shaping process, reduce deformation, ensure product quality and reliability, and solve the problems raised in the above background technology.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention proposes a drying device for processing glue that dries evenly. Through a drying method that combines preheating and laser curing, the preheating box ensures that the tape reaches a suitable temperature before entering the laser curing. This process can effectively remove surface moisture, improve the fluidity of the glue, and enhance adhesion, which not only improves work efficiency, but also improves the curing effect of the tape and the final product quality.

[0017] In this embodiment, a heating box 403 is provided at the rear end of the preheating box 4, a fan 404 is provided on one side of the heating box 403, and a connecting tube 402 is connected to the upper end of the preheating box 4. The heating box 403 is fixedly connected to the connecting tube 402 through a connecting tube 401. An electric heating rod is provided inside the heating box 403. After the electric heating rod and the fan 404 are powered on, the electric heating rod can heat the air blown out by the fan 404, and then guide and transport the air through the connecting tube 401, and enter the heating box 403 through the connecting tube 402. A temperature sensor and an air vent pipe are also provided in the heating box 403. The temperature sensor is convenient for effectively controlling the temperature in the heating box 403 to avoid damage to the tape caused by excessive heating. The preheating box 4 ensures that the tape reaches a suitable temperature before entering the laser curing. This process can effectively remove surface moisture, improve the fluidity of the glue, and enhance adhesion.
[0018] In this embodiment, the laser drying mechanism 3 includes a support frame 301, and the support frame 301 is located at the upper end of the base 1. A guide rail 302 is provided at the upper end of the support frame 301. A linear motor 303 is slidably provided at the upper end of the guide rail 302. A laser heater is installed on the linear motor 303, and there are several laser heaters. The laser heater includes a heating head 304, an optical fiber 305 and a laser 306. The laser 306 is coupled to the heating head 304 through the optical fiber 305. The heating head 304 is fixedly installed on the linear motor 303. In order to be able to The intensity and irradiation time of the laser can be controlled. The laser device of this embodiment also includes a controller, which is electrically connected to the laser 306 in the laser heater. The laser emitted by the laser 306 is transmitted to the heating head 304 via the optical fiber 305 to form a rectangular spot that irradiates the surface of the tape. By laser curing and heating the tape, the processing cost can be effectively controlled. In addition, the laser has strong penetrating ability, easy energy absorption and concentration, small thermal sensitivity effect, and can evenly heat and cure the tape, with a higher yield rate than traditional ultraviolet photolithography curing.
[0019] Laser curing adopts the principle of point light source irradiation and heating. Since the wavelength of the laser is easily absorbed by the tape, and the energy is concentrated, the heat-affected area is small, and the tape is quickly heated in a short time, the temperature reaches about 160 degrees, and the tape is completely and thoroughly cured from the inside to the outside, from hidden to visible within one minute, which greatly shortens the processing time and improves production efficiency. Due to the strong penetrating ability of the laser beam, the energy of the laser beam is easy to absorb and concentrate. In other words, laser irradiation is a three-dimensional and all-round absorption of laser energy by the tape. The irradiated tape can quickly achieve uniform heating and uniform curing from the inside to the outside, and the curing effect is better for thick layers of tape. The service life of the semiconductor laser 306 is longer, which reduces the maintenance cost.
[0020] Laser curing uses high-energy laser beams, which can be designed according to the actual production requirements through beam shaping. The curing temperature can be adjusted by controlling the power of the laser 306, and real-time monitoring can be performed. The laser spot diameter is very small, and some can even be micron-level. The laser wavelength is easy to absorb quickly and can irradiate fine glue. The irradiation point is very precise and fine, and the energy is concentrated. After the energy carried by the laser beam is quickly absorbed by the tape within the irradiation range, the tape is quickly heated and cured in a very short time, and the heat basically does not diffuse and conduct outward.
[0021] In this embodiment, vertical plates 8 are provided at the upper and lower ends of one side of the base 1, and the vertical plates 8 are fixedly connected to the base 1. The guide roller 6 and the cooling roller 7 are respectively connected to the vertical plates 8 through support rods. A material trough 101 is opened inside the base 1, and the material trough 101 is located between the guide roller 6 and the cooling roller 7. The laser-cured and heated tape is then shaped by the cooling roller 7 under the guidance of the guide roller 6. Through the guidance of the guide roller 6, the tape can maintain good shape and size consistency when passing through the cooling roller 7, reducing deformation and warping. The cooling roller 7 can effectively control the cooling rate of the tape to avoid internal defects caused by thermal stress. During the cooling process, the surface quality of the tape will be improved, reducing defects such as bubbles and wrinkles, ensuring that the tape has a smooth and uniform surface, and improving the appearance and performance of the product.
[0022] A receiving roller 502 is arranged inside the receiving box 5, and a driving motor 501 is installed at the front end of the receiving box 5, and the output end of the driving motor 501 is connected to the rotating shaft of the receiving roller 502. The receiving roller 502 is driven by the driving motor 501 to realize the winding of the tape.
[0023] Working principle: When in use, first power on the electric heating rod and the fan 404. The electric heating rod can heat the air blown out by the fan 404, and then guide and transport it through the connecting pipe 401, and enter the heating box 403 through the connecting cylinder 402. Then the coated tape enters the preheating box 4 from between the upper roller and the lower roller for preheating. Preheating can make the tape solidify faster after coating and shorten the drying time. Then the tape passes through the laser drying mechanism 3. The laser emitted by the laser 306 is transmitted to the heating head 304 through the optical fiber 305 to form a rectangular light spot on the surface of the tape. The tape is laser cured and heated by laser. The laser cured and heated tape is then shaped by the cooling roller 7 under the guidance of the guide roller 6, and then rolled into the receiving box 5.
