[0027] In order to make the technical solutions and advantages in the embodiments of the present application more clear and apparent, the exemplary embodiments of the present application are further described in detail below with reference to the drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.
[0028] Embodiment 1
[0029] As shown in the figure, the present embodiment proposes a spot ironing device, which can be arranged in a spot ironing machine and used for spot ironing and melting of a film. The spot ironing device specifically comprises: Figure 1 a heating assembly for melting the film;
[0030] a cooling assembly for cooling the film;
[0031] a controller for controlling the actions of the heating assembly and the cooling assembly.
[0032] Specifically, in the present embodiment, the heating assembly can melt the film in a predetermined area through heat conduction. The cooling assembly is arranged beside the heating assembly and can move together with the heating assembly. The cooling assembly can apply cooling gas to the film in the predetermined area, so that the heating assembly can perform cooling treatment on the melted film while heating and melting the film. The controller can adjust the position of the heating assembly and control the start and stop of the heating assembly and the cooling assembly.
[0033] More specifically, in the present embodiment, the controller can control the heating assembly to move towards or away from the film. When the heating assembly needs to melt the film on the backplane glass, the heating assembly is controlled to move towards the film. At the same time, the controller controls the cooling assembly to work and applies cooling gas to the heating area between the heating assembly and the film. When the film is melted, the heating assembly is controlled to move away from the film. At the same time, the controller controls the cooling assembly to be closed. In the present embodiment, the cooling gas is usually normal temperature air, which can achieve the purpose of cooling. Of course, other gases can also be selected according to actual conditions, which are not specially limited in the present embodiment.
[0034] More specifically, in the present embodiment, the controller can control the heating assembly to move towards or away from the film. When the heating assembly needs to melt the film on the backplane glass, the heating assembly is controlled to move towards the film. At the same time, the controller controls the cooling assembly to work and applies cooling gas to the heating area between the heating assembly and the film. When the film is melted, the heating assembly is controlled to move away from the film. At the same time, the controller controls the cooling assembly to be closed. In the present embodiment, the cooling gas is usually normal temperature air, which can achieve the purpose of cooling. Of course, other gases can also be selected according to actual conditions, which are not specially limited in the present embodiment.
[0035] The embodiment sets a cooling assembly beside the original spot ironing machine heating assembly. The cooling assembly can cool the film while the heating assembly is heating and melting the film. After the film is melted by the spot ironing, the cooling time of the film can be shortened, the film deviation when the back glass flows out of the spot ironing machine can be avoided, and the production rhythm of the workshop can not be affected.
[0036] In some optional embodiments, the heating assembly comprises:
[0037] The spot ironing welding head 1 is used to apply heat to the film.
[0038] The lifting unit is used to drive the spot ironing welding head 1 to move towards or away from the film.
[0039] Specifically, the spot ironing welding head 1 is electrically connected with the controller, and the start and stop of the spot ironing welding head 1 can be controlled by the controller. The spot ironing welding head 1 is the original welding head of the spot welding machine, and no improvement is made to it in the embodiment. The main purpose of the spot ironing welding head 1 is to provide heat to the film to melt the film.
[0040] The lifting unit (not shown in the figure) is electrically connected with the controller, and the lifting unit can be controlled by the controller to drive the spot ironing welding head 1 to move towards or away from the film. During the movement of the spot ironing welding head 1 driven by the lifting unit, the spot ironing welding head 1 maintains a stable temperature, so that the heating state can be ensured during the operation of the spot ironing machine, and the production rhythm will not be affected.
[0041] In some optional embodiments, the lifting unit is a telescopic air cylinder.
[0042] Specifically, the telescopic air cylinder can be electrically connected with the controller, or can be connected with the processor carried by the spot ironing machine itself, as long as the purpose of driving the spot ironing welding head 1 to move can be achieved. The fixed end of the telescopic air cylinder can be fixed on the shell of the spot ironing machine, and the moving end is fixedly connected with the spot ironing welding head 1. The movement position of the spot ironing welding head 1 can be determined by the extension distance of the telescopic air cylinder.
[0043] In some optional embodiments, the cooling assembly comprises:
[0044] The blowing pipe 2 is used to blow air to the film in a certain area.
[0045] The air pump 3 is used to pump cooling gas to the blowing pipe 2.
[0046] The electric valve 5 is used to control the opening and closing of the air path between the blowing pipe 2 and the air pump 3.
[0047] Specifically, the air blower 2 is positioned beside the spot welding head 1, and the airflow direction of the air blower 2 is towards the adhesive film in the designated area. The air pump 3 is connected to the air blower 2 via a gas pipe 4, allowing it to pump cooling gas into the air blower 2. An electric valve 5 is located in the gas passage between the gas pipe 4 and the air blower 2 and is electrically connected to the controller. When the heating element moves closer to the adhesive film, the controller opens the electric valve 5, causing the air pump 3 to pump cooling gas to the air blower 2, which then blows the cooling gas onto the adhesive film in the designated area. When the heating element moves away from the adhesive film, the electric valve 5 closes. During this process, the pumping speed of the air pump 3 can be adjusted based on the degree of melting or cooling of the adhesive film, thereby changing the airflow speed from the air blower 2 to the heating area.
[0048] Example 2
[0049] like Figure 2 As shown, this embodiment proposes a spot-heating machine, which includes a spot-heating device for melting and cooling the adhesive film, and the number of the spot-heating device is at least one. The specific structure and working principle of the spot-heating device can be referred to the content described in Embodiment 1, and will not be repeated in this embodiment.
[0050] In some alternative embodiments, the number of hot-melt devices inside the hot-melt machine can be set to four, depending on the actual amount of adhesive film to be melted for the back glass. Furthermore, these four hot-melt devices can be distributed at the four corners of the hot-melt station. This hot-melt station is the operating area for melting the adhesive film.
[0051] In some alternative embodiments, a conveyor 6 is provided inside the hot stamping machine.
[0052] Specifically, the conveyor 6 can be implemented using a traditional workshop production line conveyor belt. The conveyor 6 can transport the backplate glass with the adhesive film laid in the upstream laying machine to the hot stamping machine for film melting. Furthermore, after the adhesive film has melted, the backplate glass can be conveyed away from the hot stamping station to flow into downstream equipment.
[0053] In some alternative embodiments, multiple position sensors 7 are also installed inside the heat exchanger to detect the position of the back glass inside the heat exchanger.
[0054] Specifically, the multiple position sensors 7 can be installed beside the heat exchange station and electrically connected to the controller. The area enclosed by the multiple position sensors 7 is the heat exchange station. When the back panel glass is located at this heat exchange station, the controller controls the heating and cooling components to operate.
[0055] Obviously, many modifications and variations of the present application are possible in light of the above teachings. It is, therefore, to be understood that within the scope of the appended claims and their equivalents, the application can be practiced otherwise than as specifically described.
