[0017] The present application will be further described in detail below with reference to the accompanying drawings.
[0018] AsFigure 1 As shown, the device comprises a workbench 1, on which a heating station 2 and two processing stations 3 are installed side by side. The heating device is used for quickly and sufficiently heating the hot melt adhesive, and each processing station 3 is used for subsequent bonding of the hot melt adhesive with acrylic double-sided adhesive (acrylic adhesive layer) and the like. After bonding and cooling, the peeling force between the hot melt adhesive and the acrylic double-sided adhesive needs to be greater than 700 gf / 25 mm to be qualified. According to the set pressure parameters
[0019] Preferably, a control panel 9 (flat in the figure, only the side is shown) is arranged on the workbench 1, through which the machining can be controlled and the status can be displayed. When the heating temperature reaches the set temperature, the machine will issue an alarm to remind the operator to start processing according to the set pressure parameters.
[0020] As shown Figures 2-3 The heating station 2 comprises a bottom plate 11, two vertical support plates 10 are arranged side by side on both sides of the bottom plate 11, and two ends of a heating steel roller 4 and a bottom rubber roller 5 that can rotate respectively are connected to the two support plates 10. The heating steel roller 4 is located above the bottom rubber roller 5, and the two can jointly feed the hot melt adhesive passing through the middle, and the bottom rubber roller 5 is connected to a servo motor (not shown in the figure) for providing power.
[0021] One end of the heating steel roller 4 is connected to a heating rod 6, and heat-conducting oil is arranged in the heating steel roller 4. The heating rod 6 is in contact with the heat-conducting oil. By transferring heat from the heating rod 6 to the heat-conducting oil, the heating temperature in the heating steel roller 4 can be more uniform.
[0022] Two roller lifting cylinders 7 are respectively arranged on the top of the two support plates 10, and the two ends of the heating steel roller 4 are connected to the two roller lifting cylinders 7. An infrared temperature detector 8 is arranged on the side of one of the support plates 10, located above and facing the heating steel roller 4, and connected to the two roller lifting cylinders 7.
[0023] When the heating steel roller 4 is heated, its temperature needs to be limited within a range, generally about 90°C, and the allowable temperature difference is ±10°C. When the temperature of the heating steel roller 4 exceeds the upper limit of the limited temperature, the two roller lifting cylinders 7 will automatically lift the heating steel roller 4. At this time, in order to ensure that the heating steel roller 4 is uniformly heated, corresponding auxiliary wheels (not shown in the figure) can also be arranged to drive the heating steel roller 4 to continue rotating.
[0024] Preferably, two pressure sensors 12 are respectively arranged on the two supporting plates 10, and are arranged above the two ends of the heating steel roller 4, so as to sense the relevant pressure of the heating steel roller 4, and ensure the accuracy of the material walking, wherein the required pressure range of the heating steel roller 4 is 25-30KG.
