Description

Technical Field

[0001] This utility model relates to the technical field of flexible substrate board disassembly fixtures, and in particular to a disassembly fixture for a flexible substrate board of a laptop touch screen. Background Technology

[0002] With the advancement of technology, the emergence of electronic products such as mobile phones and computers has brought great convenience to people's lives. However, the large size of the main unit makes it inconvenient to travel. To facilitate carrying computers, laptops have been designed. The touch screen makes it convenient for users to operate. The flexible substrate behind the touch screen greatly reduces the overall weight of the device and can be bent and changed shape, providing users with a more flexible way of use. Moreover, the flexible substrate has strong impact resistance, which can effectively protect the computer screen when it is subjected to external impact and disperse the damage caused by the impact. However, not only when facing repair or installation, it is often necessary to use specific tools to disassemble it so that it can be reinstalled in the original way after repair. Therefore, it is particularly important to propose a disassembly jig for the flexible substrate of the laptop touch screen.

[0029] When disassembling laptop touch screen flexible substrate, the clamping structure 8 of setting can clamp different specifications of touch screen, when touch screen is clamped and fixed, the glue between touch screen and substrate is heated and melted by heating structure 4 again, finally adjust adjusting structure, so that touch screen and substrate surface are exposed, to facilitate substrate disassembly and removal.

[0030] As Figure 1 , Figure 2 , Figure 3 And Figure 5 Indicated, clamping structure 8 includes horizontal sliding groove 801 being opened in the top end of support table 2 both sides, horizontal rotating shaft 802 being rotatably connected in the interior of horizontal sliding groove 801, horizontal sliding block 803 being threadedly connected to the outer side wall of horizontal rotating shaft 802, vertical sliding block 804 being fixedly connected to the top end of horizontal sliding block 803, vertical rotating shaft 805 being rotatably connected in the interior of vertical sliding block 804 and lifting block 806 being threadedly connected to the outer side wall of vertical rotating shaft 805, the thread direction of the outer side wall both ends of horizontal rotating shaft 802 is opposite, so that the horizontal sliding block 803 of the outer side wall of horizontal rotating shaft 802 can be relatively displaced, horizontal sliding groove 801 and vertical sliding block 804 are slidingly connected, vertical sliding block 804 and lifting block 806 are slidingly connected, the outer side wall of lifting block 806 and connecting block 5 are fixedly connected.

[0031] It should be noted that when positioning different sizes of touch screens, first place the touch screen on the top end of the supporting table 2, then place the heat insulation pad between the flexible substrate and the upper polarizing plate, start the large motor at the outer end of the horizontal rotating shaft 802 to drive the horizontal sliding block 803 to slide in the horizontal sliding groove 801, then start the small motor at the top end of the vertical sliding block 804 to drive the lifting block 806 to descend to the top end of the touch screen on the outer side wall of the vertical rotating shaft 805 and abut against the touch screen, which is more convenient for positioning different sizes of touch screens, thereby facilitating the subsequent disassembly of the substrate on the touch screen of different specifications.

[0032] Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown in the figure, the heating structure 4 includes an adjusting groove 401 opened in the inner side wall of the side plate 3, a heating assembly 402 slidingly connected inside the adjusting groove 401, and adjusting bolts 403 threadedly connected to both sides of the heating assembly 402. The air outlet at the outer end of the heating assembly 402 is directly opposite the top end of the supporting table 2. The heating assembly 402 is rotationally connected with the side plate 3. The air outlet of the heating assembly 402 is provided with a page sheet that can be adjusted in the upward and downward directions, so that the air direction can be adjusted as needed during heating to prevent the upper polarizing sheet from being damaged during heating.

[0033] It should be noted that when the touch screen is positioned, the heating assembly 402 can be started to heat the touch screen at the top end of the supporting table 2. When the thickness of the touch screen to be heated is high, in order to more conveniently control the air direction of the heating assembly 402, the adjusting bolts 403 are rotated to lift the heating assembly 402 in the adjusting groove 401 to the appropriate position, and then the page sheet in the heating assembly 402 is adjusted to control the air direction of the hot air.
