Description

Technical Field

[0001] The invention relates to the technical field of touch screen production, and in particular to an edge grinding device used for touch screen production. Background Art

[0002] In the production process of touch screens, edge grinding is a crucial step, especially in the production of borderless touch screens. Borderless touch screens are usually cut from glass substrates, and transverse microcracks and sharp edges will be generated during the cutting process. These microcracks and edges are easily affected by external forces during subsequent assembly and use, causing crack expansion and even glass breakage, seriously affecting the quality and reliability of the product. Therefore, it is necessary to use edge grinding equipment to grind the edges of the touch screen to eliminate microcracks and perform chamfering, thereby improving the mechanical strength and safety of the touch screen.

[0003] In the patent titled: An edge grinding device for producing borderless touch screens, with publication number: CN113245950B, it is proposed that when the grinding wheel rotates, the edge positions on both sides of the rotation axis rotate in opposite directions, and an upward grinding force and a downward grinding force are applied to the touch screen. The force on the touch screen unit is uneven, which can easily cause cracks to expand and affect product quality. In addition, the dust generated by grinding can easily be adsorbed on the surface of the touch screen due to static electricity and cannot be cleaned. The cleanliness of the touch screen surface is poor, which affects the subsequent process flow and product quality. The airflow generated by the static eliminator is used to blow air on the touch screen surface to reduce the adsorption of dust generated during the grinding process on the touch screen surface. The surface of the polished touch screen is cleaner, but the static-eliminating airflow blown to the touch screen is blown to both sides of the touch screen. In the process of blowing, because the dust collecting mechanism is at the bottom, once the polished dust is thrown upward due to the inertia force generated during the polishing process, the dust collecting mechanism at the bottom cannot absorb the dust that has drifted upward due to insufficient suction force, which will cause a large amount of dust to adhere to the top of the chassis. This will cause the dust on the top wall of the chassis to fall due to the vibration generated during the opening process, and then fall onto the touch screen again. At the same time, dust will be scattered everywhere. Therefore, an edge grinding device for touch screen production is proposed. Summary of the invention

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Embodiment 1: Figure 1As shown, the present application is an edge grinding device for touch screen production, including a control base 100, a mobile component is installed on the control base 100, and two support frames 114 are installed on the mobile end of the mobile component. The support frame 114 is internally rotatably connected to a grinding roller 116, and the outside of the support frame 114 is fixedly connected to a first drive motor 115. The output shaft of the first drive motor 115 passes through the outer wall of the support frame 114 and is fixedly connected to the grinding roller 116. The support frame 114 is internally installed with an air outlet pipe 117 and a collection box 118, and the air outlet pipe 117 and the collection box 118 are respectively installed. The collecting box 118 is located on both sides of the grinding roller 116, and a gas delivery and adsorption component is installed on the movable component. The gas delivery end of the gas delivery and adsorption component is connected with the air outlet pipe 117, and the air inlet end of the gas delivery and adsorption component is connected with the collecting box 118. The air outlet of the air outlet pipe 117 is inclined toward the first movable seat 106. A movable slide groove 600 is provided on the control base 100, and the internal sliding connection of the movable slide groove 600 is connected with a fixed seat 101. A plurality of negative pressure adsorption holes are provided on the fixed seat 101. The touch screen is placed on the fixed seat 101 and fixed and limited by a plurality of negative pressure adsorption holes.

[0020] Specifically, during use, the staff pulls the fixing seat 101 out of the control base 100 through the movable slide groove 600. After pulling out the control base 100, the staff places the touch screen to be polished on the fixing seat 101, and adsorbs and fixes the touch screen through the negative pressure adsorption hole. After the adsorption and fixation are completed, the fixing seat 101 is pushed back to the original position and fixed by the limiting structure. The limiting of the touch screen is a prior art and will not be described in detail here.

[0021] Specifically, after the touch screen is limited and fixed, the staff starts the moving component to drive the support frame 114 and the grinding roller 116 to gradually approach the fixed touch screen. After the position of the grinding roller 116 is adjusted by the moving component, the first drive motor 115 is started to drive the grinding roller 116 to rotate, so that the touch screen is polished by the rotation of the grinding roller 116. In the process of polishing the touch screen, the dust generated by the polishing can be blown away and absorbed by the air supply and adsorption component in conjunction with the air outlet pipe 117 and the collection box 118.

[0022] Specifically, when the gas delivery adsorption component continuously delivers the gas to the inside of the air outlet pipe 117 , the gas can be blown out through the air outlet pipe 117 , and the direction of the gas blowing out is the same as the direction of the grinding roller 116 .

[0023] Furthermore, after the air outlet pipe 117 blows out the gas, it can meet the dust generated during the grinding process of the grinding roller 116, so that the gas is blown in the direction of the collection box 118. In the process of continuously blowing the gas in the direction of the collection box 118, the dust can be blown into the collection box 118 together, and the collection box 118 can continue to generate an air suction function. In the case of continuously generating an air suction process, the dust can be blown into the interior of the collection box 118 together, thereby continuously adsorbing the dust and completing the dust collection work. The air outlet pipe 117 is used for the cleaning of the dust. 17 and the collecting box 118 are respectively located on both sides of the grinding roller 116, so that in the process of the grinding roller 116 continuously rotating to generate dust, the generated dust can enter the interior of the collecting box 118 immediately after being generated, and the dust will not be scattered and drift to other locations. In addition, the air outlet duct 117 and the collecting box 118 are also relatively close to the grinding roller 116, so that the escape of dust can be minimized during the grinding process of the grinding roller 116, and the blown air flow can also assist the rotation of the grinding roller 116 to a certain extent.

[0024] like Figure 1-Figure 10 As shown, the moving assembly includes a square placing box 102, the square placing box 102 is fixedly connected to the outside of the control base 100, the inside of the square placing box 102 is fixedly connected to the second driving motor 500, the output shaft of the second driving motor 500 is fixedly connected to the screw rod 501, the external thread of the screw rod 501 is connected to the jacking moving plate 103, the top of the jacking moving plate 103 is fixedly connected to the top plate 104, the bottom of the top plate 104 is fixedly connected to the X-direction moving module 105, the outside of the X-direction moving module 105 is installed with a first moving seat 106, and the bottom of the first moving seat 106 is fixedly connected to two Y-direction moving seats. The second moving seat 108 is installed on the moving modules of the two Y-direction moving modules 107, the bottom of the second moving seat 108 is hinged with a third moving seat 110, a positioning hole 109 is opened inside the second moving seat 108, a micro motor 111 is fixedly connected inside the positioning hole 109, the output shaft of the micro motor 111 is fixedly connected to a driving pulley 112, the outside of the third moving seat 110 is fixedly connected to a driven pulley 113, the driving pulley 112 and the driven pulley 113 are connected by belt transmission, and the support frame 114 is fixedly connected to the bottom of the third moving seat 110.

[0025] Specifically, in the moving component, the second driving motor 500 can be started to drive the screw rod 501 to rotate, and during the rotation of the screw rod 501, the lifting moving plate 103 can be driven to move up and down inside the square placement box 102, and the up and down movement of the lifting moving plate 103 will drive the top plate 104 to move up and down, and the up and down movement of the top plate 104 will drive the support frame 114 to move up and down as a whole, and during the front, back, left and right movement of the support frame 114, the first moving seat 106 can be driven to move forward and backward by starting the X-direction moving module 105, and during the front and back movement of the first moving seat 106, the second moving seat 108 and the support frame 114 can be driven to move forward and backward, and after the first moving seat 106 moves to the specified position front and back , and the two Y-direction moving modules 107 can be started to drive the two second moving seats 108 to move in the left and right directions respectively, thereby driving the support frame 114 and the grinding roller 116 to approach the touch screen that needs to be polished in the left and right directions respectively. At the same time, in the further use process, the micro motor 111 can be started to drive the active pulley 112 to rotate. During the rotation of the active pulley 112, the driven pulley 113 can be driven to rotate, and the driven pulley 113 is fixed to the outside of the third moving seat 110. When the micro motor 111 drives the active pulley 112 to cooperate with the driven pulley 113 to rotate slightly, the support frame 114 can be driven to adjust the angle, thereby driving the support frame 114 and the grinding roller 116 to adjust the angle.

[0026] like Figure 1-Figure 6 As shown, the gas delivery adsorption component includes an air pump 123, which is fixedly connected to the top of the top plate 104, and the air outlet of the air pump 123 is connected to the second multi-way diverter valve 126, and the two air outlets of the second multi-way diverter valve 126 are both connected to the static eliminator 122, and the air outlet of the static eliminator 122 is connected to the air outlet conveying pipe 119, and the end of the air outlet conveying pipe 119 away from the static eliminator 122 passes through the outer wall of the support frame 114 and is connected to the air outlet pipe 117, and the air inlet of the air pump 123 is connected to the first multi-way diverter valve 124, and two air inlets of the first multi-way diverter valve 124 are both connected to the dust box 125, and the outside of the dust box 125 is connected to the air inlet collecting pipe 121, and the end of the air inlet collecting pipe 121 away from the dust box 125 passes through the outer wall of the support frame 114 and is connected to the collecting box 118.

[0027] Specifically, in the gas delivery component, the gas can be continuously delivered to the interior of the second multi-way diverter valve 126 by starting the air pump 123, and the gas delivered to the interior of the second multi-way diverter valve 126 will be continuously delivered to the interior of the static eliminator 122, and the static eliminator 122 generates ions for removing static electricity, and when the ions are generated, they are delivered to the interior of the air outlet delivery pipe 119 together with the gas generated by the air pump 123. When the ionized gas is delivered to the interior of the air outlet pipe 117 through the air outlet delivery pipe 119, the ionized gas can be removed through the air outlet pipe 117. The ionized air is ejected, and when the ionized air is ejected, the static electricity generated during the grinding process can be removed, thereby reducing the phenomenon of dust being adsorbed at different positions due to static electricity. The air outlet pipe 117 is divided into two sections, the upper end and the lower section are connected by a plurality of holes. The upper end can continuously receive ionized gas in the air outlet pipe 119 and store the ionized gas in the upper section. When the ionized gas in the upper section continues to increase, it will be evenly ejected through the holes between the upper section and the lower section, so that the ionized gas can be evenly ejected through the lower section of the air outlet pipe 117.

[0028] Furthermore, during the operation of the air pump 123, air can also be continuously inhaled through multiple air inlets outside the first multi-way diverter valve 124. During the continuous inhalation of air, the suction force generated by the air pump 123 will cooperate with the collection box 118 and the air inlet collection pipe 121 to continuously inhale dust. During the continuous inhalation process, the dust will continue to enter the interior of the dust box 125, and in the process of the gas continuously entering the interior of the dust box 125, the dust will be blocked by the internal filter of the dust box 125, thereby collecting the dust through the dust box 125.

[0029] The technical solution in the above-mentioned embodiment of the present application has at least the following technical effects or advantages: relative to the prior art, in the present embodiment, by respectively arranging an air outlet duct 117 and a collection box 118 on both sides of the grinding roller 116, ionized air is blown out through the air outlet duct 117 during the rotation of the grinding roller 116, thereby removing static electricity around the grinding roller 116, and in the process of removing static electricity, the dust generated by the grinding roller 116 grinding the touch screen can also be blown to the position of the collection box 118, and the dust is collected by the collection box 118, so that the dust will neither fall onto the touch screen nor scatter and adhere to other positions even after being blown by the gas.

[0030] Embodiment 2: Considering that the outlet direction of the air outlet pipe 117 is fixed during use, some dust may adhere to the surface of the grinding roller 116 after long-term use of the grinding roller 116. When the dust adheres to the surface of the grinding roller 116, the air outlet pipe 117 with a fixed outlet direction cannot blow the gas to the surface of the grinding roller 116 in a completely covering manner. In addition, during the grinding process, different sizes and styles of first movable seats 106 are required for touch screens with different requirements. When the first movable seat 106 is larger or smaller, the outlet direction of the air outlet pipe 117 also needs to be adjusted. In view of the above technical problems, the present application proposes the following technical solutions to solve the above technical problems, specifically: like Figure 2-Figure 5 As shown, the air outlet of the air outlet conveying pipe 119 is connected to the electric control valve 120, the outside of the air outlet conveying pipe 119 is connected to the first diversion conveying hose 200, the inner bottom wall of the air outlet pipe 117 is integrally formed with an elastic stretching membrane 203, the elastic stretching membrane 203 and the inner bottom wall of the air outlet pipe 117 form an air storage cavity, the air outlet of the first diversion conveying hose 200 is connected to the air storage cavity, and the inner side walls of the first diversion conveying hose 200 are respectively fixedly connected to the first strong magnet 201 and the first electromagnet 202.

[0031] Specifically, during use, when a smaller grinding roller 116 is replaced, the electric control valve 120 can be closed. When the electric control valve 120 is closed, the gas will be transported to the inside of the first diversion delivery hose 200. When the gas enters the inside of the first diversion delivery hose 200, the staff can energize the first electromagnet 202. When the first electromagnet 202 is energized, a repulsive force can be generated between the first electromagnet 202 and the first strong magnet 201. When the repulsive force is generated, the first diversion delivery hose 200 and the elastic stretch film 2 03 are interconnected, and when interconnected, the gas entering the first diversion conveying hose 200 can be concentrated into the gas storage cavity. When enough gas enters the gas storage cavity, the elastic stretch membrane 203 will extend and expand. When the elastic stretch membrane 203 extends and expands, the shape of the outlet of the air outlet pipe 117 can be changed. By changing the shape of the outlet of the air outlet pipe 117, the direction in which the gas is ejected from the outlet of the air outlet pipe 117 can be changed, so that when the smaller grinding roller 116 is replaced, the gas can be continuously transported to the outside of the smaller grinding roller 116.

[0032] like Figure 2-Figure 7As shown, the air outlet of the air outlet conveying pipe 119 is connected to the second diversion conveying hose 204, and the end of the second diversion conveying hose 204 away from the air outlet conveying pipe 119 is fixedly connected to the diversion box 207, and the outside of the diversion box 207 is connected to two pushing bags 208, and the end of the pushing bags 208 away from the diversion box 207 is fixedly connected to the inner bottom wall of the air outlet pipe 117, and the bottom side walls of the air outlet pipe 117 are both semi-hard elastic rubber, and the two pushing bags 208 are respectively located on both sides of the elastic extension membrane 203.

[0033] Specifically, when a larger grinding roller 116 is installed, the first electromagnet 202 can be de-energized, so that the first electromagnet 202 and the first strong magnet 201 close the first shunt delivery hose 200, and the second electromagnet 206 is energized. In the process of energizing the second electromagnet 206, a repulsive force is generated between the second electromagnet 206 and the second strong magnet 205, thereby opening the connecting space between the second shunt delivery hose 204 and the shunt box 207, so that the gas continues to enter the inside of the shunt box 207. When the gas continues to enter When the gas enters the diversion box 207, the diversion box 207 will divert the internal gas, so that the gas is diverted to the two pushing bags 208. When the gas continues to enter the pushing bags 208, the pushing bags 208 will expand. When the pushing bags 208 expand, the inner wall and bottom wall of the air outlet pipe 117 will be pushed to deform, thereby expanding the opening degree of the outlet of the air outlet pipe 117, further increasing the gas ejection range, and adapting to the shape of the larger diameter grinding roller 116, thereby delivering more anti-static airflow to the outside of the larger diameter grinding roller 116.

[0034] The technical scheme in the above-mentioned embodiment of the present application has at least the following technical effects or advantages: relative to embodiment one, in this embodiment, by injecting gas into the first diversion conveying hose 200, the elastic stretch membrane 203 can be expanded outward, and when the elastic stretch membrane 203 expands outward, the outlet degree of the air outlet pipe 117 can be reduced so as to adapt to the smaller grinding roller 116, so that the anti-static gas can be accurately sprayed to the outside of the smaller grinding roller 116, and at the same time, by conveying gas to the inside of the second diversion conveying hose 204, the two propulsion bags 208 can be expanded, and when the two propulsion bags 208 expand, the inner bottom wall of the air outlet pipe 117 can be supported and pushed, thereby expanding the outlet opening degree of the air outlet pipe 117, further increasing the amount of gas blown out, so that even when a larger grinding roller 116 is installed, it is still possible to ensure that the gas is continuously delivered to the outside of the grinding roller 116.

[0035] Embodiment 3: Considering that when the elastic stretch film 203 expands, although the opening diameter of the air outlet of the air outlet pipe 117 can be adjusted, when the elastic stretch film 203 expands, the air storage cavity is filled with gas, and the bottom side wall of the air outlet pipe 117 is also semi-hard elastic rubber. Therefore, when the air outlet pipe 117 blows out gas, the gas blown to the surface of the elastic stretch film 203 will cause the surface of the elastic stretch film 203 and the bottom of the air outlet pipe 117 to continue to shake. In the case of continuous shaking, the direction of gas blowing may change due to the shaking, and the gas cannot be stably blown to the grinding position of the grinding roller 116. In view of the above technical problems, the present application proposes the following technical solutions to solve the above technical problems, specifically: like Figure 2-Figure 9 As shown, the elastic stretch film 203 and the lower inner part of the air outlet pipe 117 made of elastic material are integrally formed with an inner storage tank 300 , and the inner storage tank 300 is filled with a lower supporting electrorheological fluid 301 .

[0036] Specifically, during use, when the gas is filled into the gas storage cavity and the elastic stretch film 203 is expanded, the lower supporting electrorheological fluid 301 inside the inner storage slot 300 can be energized through a conductive wire connected to the outside. When the lower supporting electrorheological fluid 301 is energized, the lower supporting electrorheological fluid 301 can be hardened. When the lower supporting electrorheological fluid 301 is hardened, a hard support can be formed for the elastic stretch film 203 and the bottom of the air outlet pipe 117. When the hard support is formed, it can be ensured that even when the air outlet pipe 119 transports gas, the gas will not be blown to the surface of the elastic stretch film 203 to cause the elastic stretch film 203 to rebound repeatedly, thereby further avoiding the phenomenon of misalignment of the gas blowing direction caused by repeated rebound of the elastic stretch film 203.

[0037] The technical solution in the above-mentioned embodiment of the present application has at least the following technical effects or advantages: relative to the second embodiment, in the present embodiment, by energizing the lower supporting electrorheological fluid 301 located inside the inner storage tank 300, the lower supporting electrorheological fluid 301 can be hardened after being energized. After the lower supporting electrorheological fluid 301 is hardened, a hard support can be formed for the elastic stretch membrane 203 and the soft bottom of the air outlet pipe 117. When the hard support is formed, the phenomenon of unstable blowing direction caused by repeated rebound of the elastic stretch membrane 203 when the gas is blown to the surface of the elastic stretch membrane 203 can be avoided.

[0038] Embodiment 4: When a large amount of gas enters the gas storage cavity and the elastic stretch film 203 expands, it will squeeze the lower supporting electrorheological fluid 301 located inside the inner storage tank 300. The flowing lower supporting electrorheological fluid 301 may cause all the lower supporting electrorheological fluid 301 to be dispersedly accumulated under the inner storage tank 300 when squeezed. When the lower supporting electrorheological fluid 301 is dispersed, it will be impossible to complete continuous hard support. In view of the above technical problems, the present application proposes the following technical solutions to solve the above technical problems, specifically: like Figure 2-Figure 9 As shown, a secondary soft film 302 is integrally formed on one side of the elastic stretch film 203 close to the inner bottom wall of the air outlet duct 117, a temporary storage cavity is formed between the secondary soft film 302 and the elastic stretch film 203, and a flow hole is opened on the outside of the elastic stretch film 203, which is connected to the temporary storage cavity and the inner storage groove 300.

[0039] Specifically, by setting the secondary soft film 302, when the elastic stretch film 203 is in a normal state, the lower supporting electrorheological fluid 301 will be located inside the temporary storage cavity, and when all the gas enters the gas storage cavity, the gas will gradually squeeze the secondary soft film 302, and during the expansion of the elastic stretch film 203, the secondary soft film 302 will gradually squeeze the lower supporting electrorheological fluid 301 into the inner storage tank 300, thereby avoiding the lower supporting electrorheological fluid 301 from being inside the inner storage tank 300 from the beginning, resulting in the elastic stretch film 203 as a whole expanding and stretching, and the lower supporting electrorheological fluid 301 being expanded and squeezed to various places, causing excessive dispersion and accumulation.

[0040] like Figure 6 As shown, the secondary soft film 302 is integrally formed with a plurality of micro electromagnet groups 400 on the outside, and the elastic stretch film 203 is integrally formed with a plurality of conductive rods 401 on the outside. The plurality of conductive rods 401 penetrate the outer wall of the elastic stretch film 203 and are connected to the inner storage slot 300 .

[0041] Specifically, considering that during use, the use of gas alone to squeeze the secondary soft film 302 may not allow the lower supporting electrorheological fluid 301 located inside the storage cavity to completely enter the inner storage tank 300, before the lower supporting electrorheological fluid 301 is energized and hardened, the multiple micro-electromagnet groups 400 can be energized, and during the process of energizing the multiple micro-electromagnet groups 400, adsorption can be generated between the multiple micro-electromagnet groups 400 and the multiple conductive rods 401. When the multiple micro-electromagnet groups 400 adsorb the conductive rods 401, the secondary soft film 302 can be driven to cling to the inner wall of the elastic stretch film 203, and the secondary soft film 302 can be driven to cling to the inner wall of the elastic stretch film 203. 02 When the elastic stretch membrane 203 is in close contact with the inner wall surface, the lower supporting electrorheological fluid 301 located inside the storage cavity can be smoothly squeezed into the inner storage tank 300, and when the air outlet pipe 117 continues to blow out wind with ions, the overall formed current can also be introduced into the lower supporting electrorheological fluid 301 located inside the inner storage tank 300 through the conductive rod 401, so that the lower supporting electrorheological fluid 301 is energized through the conductive rod 401. Under normal conditions, it is still necessary to use an external conductive wire to be inserted into the inner storage tank 300, so as to energize the lower supporting electrorheological fluid 301 that enters the inner storage tank 300.

[0042] like Figure 1 and Fig.11 As shown, the outside of the air inlet collecting tube 121 is integrally formed with an outer storage capsule 700, the interior of the outer storage capsule 700 is filled with an outer supporting electrorheological fluid 701, and the outer walls of the outer storage capsule 700 are fixedly connected to the outer walls of the second movable seat 108 and the third movable seat 110 respectively.

[0043] Specifically, during the overall use process, the outer supporting electrorheological fluid 701 located inside the outer storage bag 700 can be energized through the conductive wire to harden the outer supporting electrorheological fluid 701. During the hardening process of the outer supporting electrorheological fluid 701, support can be provided to the inclined support frame 114, and the grinding roller 116 can be provided with auxiliary support during the working process to increase its stability.

[0044] The technical solution in the above-mentioned embodiment of the present application has at least the following technical effects or advantages: relative to the third embodiment, in the present embodiment, the temporary storage cavity formed by the secondary soft film 302 can provide a storage space for the lower supporting electrorheological fluid 301, so that when it is necessary to inject the lower supporting electrorheological fluid 301 into the inner storage groove 300, the lower supporting electrorheological fluid 301 located in the temporary storage cavity can be squeezed into the inner storage groove 300 by squeezing the secondary soft film 302. When the elastic stretching film 203 is in an expanded state and when the lower supporting electrorheological fluid 301 is squeezed into the inner storage groove 300, the lower supporting electrorheological fluid 301 entering the inner storage groove 300 can be formed into a continuous bordering state, thereby avoiding the phenomenon of separation and accumulation, and avoiding the phenomenon of being unable to form a continuous hardened support after power-on.

[0045] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
