Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-5 The utility model provides a technical solution: a hot melt adhesive laminating device with a preheating function, comprising: a base 1, and a first support frame 2 arranged at the rear side of the base 1, and further comprising:

[0027] A driving component 3 is installed inside the base 1, and a mounting plate 4 is provided on the upper side of the driving component 3, a limiting frame 5 is provided inside the mounting plate 4, and a heating tube 6 is provided in the middle of the limiting frame 5, and a temperature conducting plate 7 is provided on the upper side of the heating tube 6, a second motor 8 is provided at the upper left end of the first support frame 2, and a second connecting rod 9 is provided at the lower end of the second motor 8, a second support frame 10 is provided at the lower end of the second connecting rod 9, and a first guide rod 13 is provided on the rear side of the second support frame 10, a material storage trough 11 is provided inside the second support frame 10, and a material inlet 12 is provided on the right side of the material storage trough 11, a third motor 14 is provided at the upper right end of the first support frame 2, and the lower end of the third motor 14 is connected to the third connecting rod 15, the lower end of the third connecting rod 15 is provided with a third support frame 16, and a second guide rod 17 is provided on the rear side of the third support frame 16, constituting a complete hot melt adhesive bonding device.

[0028] like Figure 1 and Figure 2 As shown, the driving assembly 3 includes a first motor 301 installed on the left side of the base 1, and the right side of the first motor 301 is connected to the first connecting rod 302, and a guide block 303 is provided in the middle of the first connecting rod 302, the first connecting rod 302 and the guide block 303 are relatively threadedly connected, and the guide block 303 and the base 1 are relatively slidably arranged, and the longitudinal section of the guide block 303 is a "T"-shaped structure. The first motor 301 drives the first connecting rod 302 to rotate inside the base 1, so that the first connecting rod 302 pushes the guide block 303 to move to the right. At this time, the guide block 303 drives the mounting plate 4, the heat conduction plate 7 and the touch screen to move to the lower end of the third support frame 16, thereby completing the driving work of the touch screen.

[0029] like Figure 1 、 Figure 3 and Figure 4As shown, the limit frame 5 and the mounting plate 4 are arranged to slide relative to each other, and the cross-section of the heating tube 6 arranged on the inner side of the limit frame 5 is a wavy structure, the heat conducting plate 7 and the mounting plate 4 are relatively engaged with each other, the second connecting rod 9 and the second support frame 10 are relatively threaded, and the second support frame 10 and the first guide rod 13 are relatively slidable. By placing the touch screen on the upper side of the heat conducting plate 7, heat is dissipated through the heating tube 6 arranged inside the limit frame 5. At this time, due to the thermal conductivity of the heat conducting plate 7, the heating tube 6 quickly heats the touch screen and maintains the touch screen at a set temperature. At this time, hot melt adhesive is poured into the interior of the second support frame 10 through the feeding port 12, and at the same time, the second motor 8 drives the second connecting rod 9 to move at the lower end of the first support frame 2, so that the second connecting rod 9 pushes the second support frame 10 to move downward along the first guide rod 13 and contact the heat conducting plate 7. At this time, the hot melt adhesive falls into the upper side of the touch screen through the storage trough 11. At the same time, due to the influence of high temperature, the fluidity and adhesion of the hot melt adhesive on the upper side of the touch screen are greatly improved, thereby completing the rapid application of the hot melt adhesive.

The third guide rod 20 and the third support frame 16 are arranged to slide relative to each other, and the third guide rod 20 is arranged symmetrically about the central axis of the pressing plate 19. By installing the touch screen cover plate inside the third support frame 16, the third motor 14 cooperates with the third connecting rod 15 to push the third support frame 16 to move downward along the second guide rod 17 and contact the heat conduction plate 7. At this time, the hot melt adhesive sticks the touch screen and the touch screen cover plate together, and at the same time, the electric telescopic rod 18 pushes the pressing plate 19 to move downward along the third guide rod 20, so that the pressing plate 19 presses the touch screen cover plate, and promotes the rapid curing of the hot melt adhesive through appropriate pressure to stick the touch screen and the touch screen cover plate together.
