[0039] Application Examples

[0040] Applying adhesive to the bezel of a curved screen significantly improves the overall structural strength of the phone, making it more drop-resistant and durable. Secondly, due to the design characteristics of curved screen phones, gaps easily form between the screen and the frame. Adhesive application effectively seals these gaps, preventing dust, moisture, and other external impurities from entering, thus extending the phone's lifespan and maintaining its good appearance. Furthermore, adhesive application technology can also enhance the phone's water resistance, providing additional protection. However, the adhesive used for applying adhesive to the phone's frame is a spatial curved surface, which traditional three-axis printing equipment cannot accurately print.

[0041] The working principle of the curing-following five-axis printing system used for dispensing adhesive onto the curved screen bezel of a mobile phone in this embodiment is as follows:

[0042] The relative position and angle between the curing follow-up mechanism and the printing mechanism are adjusted using an adjustment mechanism:

[0043] A lifting assembly drives the light generator to move along the Z-axis relative to the print head, and a flipping assembly drives the light generator to flip around the print head. A lifting electric cylinder drives the slider to move the light generator along a slide rail, and a lifting limit block limits the stroke of the light generator along the slide rail. A flipping electric cylinder drives the light generator to flip around a flipping axis, and a flipping limit block limits the relative angle between the light generator and the print head. The structural diagram of the light generator in its initial state is shown below. Figure 4 As shown, a schematic diagram of the light generator in its flipped state is as follows: Figure 5 As shown;

[0044] A printing mechanism is used to print UV-curable adhesive onto the surface of a curved screen bezel on a mobile phone, and an observation mechanism is used to monitor the printing status of the printing mechanism in real time.

[0045] A light generator is used to emit curing light to cure the light-curing adhesive that flows from the printing mechanism onto the surface of the curved screen bezel of the mobile phone.

[0046] In summary, this invention integrates the printing mechanism, adjustment mechanism, and curing follow-up mechanism onto the Z-axis of a five-axis printing device. The adjustment mechanism adjusts the relative position and angle between the curing follow-up mechanism and the printing mechanism, solving the verticality and straightness problems of five-axis printing. It also addresses the issue of existing five-axis printing devices where the UV curing lamp cannot flexibly adjust to changes in the five-axis direction when dispensing adhesive onto curved surfaces, leading to high difficulty in curing. A lifting component drives the light generator to move along the Z-axis relative to the printing needle, and a flipping component drives the light generator to rotate around the printing needle, adjusting the relative angle between the light generator and the printing needle. This allows the UV curing lamp to flexibly adjust to changes in the five-axis direction, reducing the difficulty of curing. A lifting limit block limits the travel of the light generator along the slide rail, and a flipping limit block limits the relative angle between the light generator and the printing needle. This makes the degree to which the adjustment mechanism adjusts the relative position and angle between the curing follow-up mechanism and the printing mechanism controllable, improving the accuracy of photocuring. Therefore, this invention effectively overcomes the various shortcomings of existing technologies and has high industrial application value.
