Description

Technical Field

[0001] This invention relates to the field of electronic product technology, and more specifically to a rolling friction heating platform. Background Technology

[0002] Full lamination is a technology that seamlessly bonds a touchscreen and a display screen together using materials such as water-based adhesives or optical adhesives. The following is a detailed introduction:

[0003] In terms of manufacturing process, vacuum hard-to-hard bonding equipment is generally used to tightly bond the panel and the touch screen. Commonly used bonding materials include OCA optical adhesive and water-based adhesive. Among them, OCA optical adhesive has superior light transmittance, clarity, and adhesion, while water-based adhesive is lower in cost but relatively more difficult to apply.

[0004] Display Performance: Full lamination technology eliminates the air gap between screens, significantly reducing light reflection and light loss, thereby improving brightness and contrast for a clearer and more transparent picture and better visual effects; Screen Cleanliness: The absence of air gaps effectively prevents dust, moisture, and other impurities from entering, keeping the screen clean and reducing display problems caused by dust and other factors; Touch Performance: The tight integration of the touchscreen and display panel not only enhances strength but also effectively reduces noise interference with touch signals, improving the smoothness and accuracy of touch operations for a more natural and fluid user experience;

[0005] Currently, in the industry, defective products in the full lamination process require rework. This necessitates placing the CG and LCM on a heated platform and repeatedly pulling the fishing line left and right to cut the OCA (Optical Cordless Acrylic Acid) between the CG and LCM for rework. However, traditional fishing line separation devices have very sharp platform edges (e.g., ...). Figure 1 As shown in the figure, the fishing line is prone to breakage due to sliding friction after contact with it. In addition, the fishing line's abrasion resistance is reduced by heat during operation, making it more likely to break. After the fishing line breaks, it needs to be reconnected, which takes a long time to complete a single piece, wasting material and labor costs.

[0006] The information disclosed in the background section is only intended to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0007] The purpose of this invention is to design a rolling friction heating platform that prevents the fishing line from being broken by the sharp edges of the heating platform and improves its service life, thereby overcoming the aforementioned shortcomings in the technology.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a rolling friction heating platform for processing OCA bonded between CG and LCM, comprising an electrical control box, a heating platform mounted on the top of the electrical control box, the four sides of the top of the heating platform being acute angles, CG contacting the top of the heating platform, and a repeatedly pulled thread between CG and LCM, wherein a receiving groove is opened on one side of the heating platform on the top of the electrical control box, a lifting roller in contact with the thread is arranged in the receiving groove, an active adjustment component is installed at one end of the lifting roller, and a driven adjustment component is installed at the other end, both the driven adjustment component and the active adjustment component being fixedly connected to the outer wall of the electrical control box;

[0009] The distance between the lifting roller and the top surface of the heating platform is adjusted by active and passive adjustment components, so that the yarn becomes rolling contact when it is repeatedly pulled on the lifting roller. While not contacting the sharp edge of the heating platform, the heat on the yarn is transferred to the lifting roller for cooling.

[0010] Preferably, the active adjustment component includes a first positioning block fixedly installed on the outer wall of the electrical control box, a micrometer fixedly installed at the bottom of the first positioning block, a first slider vertically slidably installed on one side of the first positioning block, a first support block and a guide plate fixedly installed on the side wall of the first slider, a guide groove opened in the guide plate, and a guide rod slidably installed in the guide groove. The guide rod is threadedly connected to the side wall of the first positioning block. The output end of the micrometer is vertically upward and in contact with the bottom surface of the first slider. The end of the lifting roller is detachably connected to the top of the first support block.

[0011] Preferably, the driven adjustment component includes a slide rail fixedly installed on the outer wall of the electrical control box, a second slider vertically slidably installed on the slide rail, and a second support block fixedly installed on the second slider. The second support block is detachably connected to the end of the lifting roller, and the first support block and the second support block are on the same plane.

[0012] Preferably, the lifting roller includes a connecting roller installed between the first support block and the second support block, and two rolling elements rotatably mounted on the connecting roller. The central axis of each rolling element coincides with the central axis of the connecting roller, and the two ends of the thread contact the outer peripheral surfaces of the two rolling elements respectively.

[0013] Preferably, the connecting roller includes a first column in contact with the first support block, a first shaft fixedly installed at the end of the first column, a threaded column fixedly installed at the end of the first shaft, a second column in contact with the second support block, a second shaft fixedly installed at the end of the second column, a threaded hole at the end of the second shaft, and a sleeve sleeved over the first column and the second column. The threaded column is threadedly connected to the threaded hole, and the two rolling elements are respectively sleeved over the first shaft and the second shaft. The sleeve is located between the two rolling elements.

[0014] Preferably, both the first column and the second column have blind holes at opposite ends, and the first support block and the second support block each have mounting columns fixedly installed at opposite ends that are interference-fitted with the blind holes.

[0015] Preferably, the rolling element includes two rings, a hollow column disposed outside the two rings, a plurality of vent holes opened at both ends of the outer circumferential surface of the hollow column, and a plurality of blades arranged in a circumferential array and fixedly installed between the hollow column and the rings.

[0016] Preferably, two retaining rings are fixedly installed on the outer circumferential surface of the hollow column, and the distance between the two retaining rings is smaller than the distance between the vent holes at both ends of the outer circumferential surface of the hollow column.

[0017] Preferably, the hollow column, the blade, the ring, and the retaining ring are all metal components with a thickness of less than 0.1 mm.

[0018] Preferably, both the first column and the second column are rubber-coated rollers.

[0019] The technical effects and advantages provided by the present invention in the above technical solution are as follows:

[0020] 1. This invention, through the active adjustment of the gold, the driven adjustment component and the lifting roller, can adjust the wire to prevent it from being scraped by line contact sliding friction with the sharp edge of the heating platform when processing the OCA bond between CG and LCM, thereby avoiding the wire breakage caused by sliding friction with the sharp edge.

[0021] 2. This invention changes the sliding friction between the wire and the acute edge of the platform to the rolling friction of the lifting roller, reducing wear caused by friction and improving the service life of the wire. At the same time, when the wire is repeatedly pulled left and right at an angle downward on the lifting roller, the wire that was originally in contact with CG, LCM and OCA will come into contact with the surface of the rolling parts on the lifting roller, thereby transferring heat to the rolling parts and preventing the wire from losing its wear resistance due to high temperature, thus further improving the service life of the wire.

[0022] 3. At the same time, when the yarn of the present invention rolls and rubs on the rolling element, the rolling element will rotate, thereby driving the internal blades to rotate, introducing air into the interior and then discharging it, thereby reducing the heat of the rolling element, so that every time the yarn moves from contact with CG, LCM, OCA to the rolling element, the temperature of the rolling element is lower than the temperature of the yarn to absorb heat.

[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 Figure 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] Therefore, we opened a receiving groove 7 on one side of the heating platform 4, and installed a lifting roller 8 in the receiving groove 7. The lifting roller 8 consists of a connecting roller 81 and two rolling parts 82 rotatably connected to the connecting roller 81. The connecting roller 81 consists 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, and a section opened at the end of the second shaft 815. The component consists of a threaded hole 816 and a sleeve 817 fitted over the first post 811 and the second post 814. Both the first post 811 and the second post 814 are rubber-coated rollers, and each has a blind hole 818 at one of its opposite ends. The rolling element 82 consists of two rings 821, a hollow post 822 surrounding the two rings 821, multiple vent holes 823 at both ends of the outer circumference of the hollow post 822, and multiple blades arranged in a circular array fixed between the hollow post 822 and the rings 821. The hollow column 822 consists of a blade 824 and two retaining rings 825 fixedly installed on its outer circumference. All components, including the hollow column 822, blade 824, rings 821, and retaining rings 825, are made of metal, such as copper, with a thickness of less than 0.1 mm, achieving a lightweight and highly conductive effect. Furthermore, the distance between the two retaining rings 825 and the two rings 821 is smaller than the distance between the vent holes 823 at both ends of the hollow column 822. This allows the wire 6 to dissipate heat when pulled diagonally downwards and left and right along the hollow column 822. The heat is transferred to the hollow column 822 through contact. The two hollow columns 822 rotate in opposite directions. The retaining ring 825 can prevent the wire 6 from deviating from the hollow column 822 onto the first column 811, the second column 814 and the sleeve 817. When the hollow column 822 rotates, it will drive the blade 824 to rotate, so that air is drawn in from the vent 823 at one end and then discharged from the vent 823 at the other end, so as to dissipate the heat from the hollow column 822, the blade 824 and the ring 821 into the air, thereby achieving the purpose of cooling the wire 6.

[0042] Furthermore, we install an active adjustment component 9 and a passive adjustment component 10 at the opposite ends of the first column 811 and the second column 814, respectively. The active adjustment component 9 includes a first positioning block 91 fixedly installed on the outer wall of the electrical control box 3, a micrometer 92 fixedly installed at the bottom of the first positioning block 91, a first slider 93 vertically slidably installed on one side of the first positioning block 91, a first support block 94 and a guide plate 95 fixedly installed on the side wall of the first slider 93, a guide groove 96 opened in the guide plate 95, and a guide rod 97 slidably installed in the guide groove 96. The guide rod 97 is threadedly connected to the side wall of the first positioning block 91, and the output end of the micrometer 92 is vertically upward and in contact with the bottom surface of the first slider 93. The passive adjustment component 10 includes a slide rail 101 fixedly installed on the outer wall of the electrical control box 3, a second slider 102 vertically slidably installed on the slide rail 101, and a second support block 103 fixedly installed on the second slider 102. The second support block 103 is connected to the lifting roller 8. The ends are detachably connected. The first support block 94 and the second support block 103 are on the same plane, and each of the first support block 94 and the second support block 103 is fixedly installed with a mounting post that is interference fit with the blind hole 818 at one end. Therefore, we can adjust the height of the first slider 93 by rotating the input end of the micrometer 92. The first slider 93 drives the first support block 94, and the first support block 94 drives the lifting roller 8 through the mounting post. The lifting roller 8 drives the second support block 103, and the second support block 103 drives the second slider 102 to slide on the guide rail, thereby adjusting the distance between the hollow column 822 and the heating platform 4. This makes the height between the wire 6 and the heating platform 4 change when the wire 6 rolls 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. Combined with the heat dissipation effect of the rolling element 82 during rotation, the possibility of breakage of the wire 6 is further reduced.

[0043] When using this device, firstly, based on the thickness of CG1, the distance between the fishing line 6 and the heating platform 4 when it is hung on the hollow column 822 is adjusted by rotating the micrometer 92. This ensures that when the fishing line is repeatedly pulled diagonally downwards, it will not come into contact with the acute angle 5 at the top of the heating platform 4 for sliding friction, but will instead directly roll and rub against the hollow column 822. While transferring heat to the hollow column 822, it also drives the hollow column 822 to rotate, thereby causing the blades 824 to draw in and then expel air, carrying away the heat from the hollow column 822. This achieves the dual purpose of changing friction and cooling, thus improving the service life of the fishing line.

[0044] It is important to note that the constructions and arrangements of this application shown in several different exemplary embodiments are merely illustrative. Although only a few embodiments are described in detail in this disclosure, those who consult this disclosure will readily understand that many modifications are possible (e.g., changes in the size, dimensions, structure, shape and proportion of various elements, as well as parameter values ​​(e.g., temperature, pressure, etc.), installation arrangements, use of materials, color, orientation, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in this application.
