[0038] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0040] This invention provides, for example Figures 1-12 The diagram illustrates a rolling friction heating platform used to process OCA bonded between CG1 and LCM2. It includes a control box 3 (as in the prior art), with a heating platform 4 mounted on top of the control box 3. The four edges of the heating platform 4 are acute angles 5. CG1 is bonded to the top surface of the heating platform 4. The heating platform 4 transfers heat to CG1, causing the OCA to reach a certain temperature and become rubbery. Then, a thread 6 is placed between CG1 and LCM2, and the platform is repeatedly pulled left and right to gradually move the thread 6 from one end of CG1 and LCM2 to the other. This process removes OCA. However, since the four sides of the top of the heating platform 4 are acute angles 5, when the two ends of the wire 6 are repeatedly pulled diagonally downwards and left and right, the wire 6 will scrape and slide against the acute angles 5 of the heating platform 4. In addition, the wire 6 will also absorb heat when scraping off OCA. Since the wire 6 is generally made of fishing line, the internal structure of the fishing line ages after being heated, and its wear resistance decreases. The combination of these two factors makes the wire 6 easy to break during operation. At this time, the staff needs to reconnect the wire. The operation of a single piece takes a long time, wastes material costs, and wastes labor costs.

[0041] To this end, the heating platform 4 is provided with a containing groove 7 on one side, and a jacking roller 8 is arranged in the containing groove 7. The jacking roller 8 is composed of a connecting roller 81 and two rolling members 82 rotatably connected to the connecting roller 81. The connecting roller 81 is composed of a first column 811, a first shaft 812 fixedly installed at the end of the first column 811, a threaded column 813 fixedly installed at the end of the first shaft 812, a second column 814 in contact with the second support block 103, a second shaft 815 fixedly installed at the end of the second column 814, a threaded hole 816 formed at the end of the second shaft 815, and a sleeve 817 sleeved on the first column 811 and the second column 814. Here, the first column 811 and the second column 814 are both rubber-coated rollers, and blind holes 818 are formed at the ends of the first column 811 and the second column 814 opposite to each other. The rolling member 82 is composed of two annular rings 821, a hollow column 822 arranged outside the two annular rings 821, a plurality of air holes 823 formed at the outer circumferential surface of the hollow column 822 at both ends, a plurality of blades 824 fixedly installed between the hollow column 822 and the annular ring 821 and arranged in a circumferential array, and two stop rings 825 fixedly installed on the outer circumferential surface of the hollow column 822. Here, the hollow column 822, the blades 824, the annular ring 821, and the stop ring 825 are all metal members, such as copper, with a thickness less than 0.1 mm, achieving the effects of lightness and high thermal conductivity. The distance between the two stop rings 825 and the two annular rings 821 is less than the distance between the air holes 823 at both ends of the hollow column 822. When the silk thread 6 is pulled left and right downward on the hollow column 822, heat is transferred to the hollow column 822 through contact. The two hollow columns 822 rotate in opposite directions, and the stop ring 825 can prevent the silk thread 6 from deviating from the hollow column 822 to the first column 811, the second column 814, and the sleeve 817. When the hollow column 822 rotates, the blades 824 rotate, so that air is sucked from the air holes 823 at one end and then discharged from the air holes 823 at the other end, discharging heat on the hollow column 822, the blades 824, and the annular ring 821 to the air, achieving the purpose of cooling the silk thread 6.

[0042] And we install the active adjusting part 9 and the driven adjusting part 10 on the opposite ends of the first column 811 and the second column 814 respectively, the active adjusting part 9 comprises the first positioning block 91 fixedly installed on the outer wall of the electric control box 3, the micrometer 92 fixedly installed on the bottom of the first positioning block 91, the first sliding block 93 vertically and slidingly installed on one side of the first positioning block 91, the first supporting block 94 and the guide piece 95 fixedly installed on the side wall of the first sliding block 93, the guide groove 96 opened in the guide piece 95, and the guide rod 97 slidingly installed in the guide groove 96, the guide rod 97 is threadedly connected with the side wall of the first positioning block 91, and the output end of the micrometer 92 is vertically upwardly in contact with the bottom surface of the first sliding block 93; the driven adjusting part 10 comprises the slide rail 101 fixedly installed on the outer wall of the electric control box 3, the second sliding block 102 vertically and slidingly installed on the slide rail 101, and the second supporting block 103 fixedly installed on the second sliding block 102, the second supporting block 103 is detachably connected with the end of the jacking roller 8, the first supporting block 94 and the second supporting block 103 are in the same plane, and the opposite ends of the first supporting block 94 and the second supporting block 103 are fixedly installed with the mounting column in interference fit with the blind hole 818; therefore, we can rotate the input end of the micrometer 92 to adjust the height of the output end of the micrometer 92 to jack up the first sliding block 93, the first sliding block 93 drives the first supporting block 94, the first supporting block 94 drives the jacking roller 8 through the mounting column, the jacking roller 8 drives the second supporting block 103, and the second supporting block 103 drives the second sliding block 102 to slide on the guide rail, so as to adjust the distance between the hollow column 822 and the heating platform 4, so that the height between the wire 6 and the heating platform 4 changes when the wire 6 is connected on the hollow column 822, so that the wire 6 does not have line contact friction with the acute angle 5 edge of the heating platform 4, and cooperates with the heat dissipation effect of the rolling part 82 when rotating, further reduces the possibility of breaking as the wire 6;

[0043] When using the device, first, according to the thickness of the CG1, rotate the micrometer 92 to adjust the distance between the wire 6 hung on the hollow column 822 and the heating platform 4, so that when the fishing line is repeatedly pulled in the obliquely downward direction, the acute angle 5 edge of the heating platform 4 does not contact and slide with the wire 6, but directly rolls with the hollow column 822, at the same time of transferring heat to the hollow column 822, drives the hollow column 822 to rotate, thereby driving the blade 824 to suck air and then discharge, taking away the heat on the hollow column 822, achieving the dual purpose of changing friction and cooling, and improving the service life of the fishing line.

[0044] It is important to note that the construction and arrangement of the application shown in the various exemplary embodiments is illustrative only. Although only a few embodiments have been described in detail in this disclosure, those skilled in the art who review this disclosure will readily appreciate that many modifications are possible (e.g., variations in sizes, dimensions, structures, shapes and proportions of the various elements, values of parameters, mounting arrangements, use of materials, colors, orientations, etc.) without materially departing from the novel teachings and advantages of the subject matter described in the application.
