Description

Technical Field

[0001] This application relates to the field of mobile phone screen grinding equipment technology, and in particular to a grinding device for processing mobile phone screens. Background Technology

[0002] In the production process of mobile phone screens, screen components made of glass substrates or other materials need to be ground to remove excess material generated during processing. This helps ensure that the screen components achieve the required size and shape accuracy, and improves the surface smoothness of the screen by removing scratches, defects and uneven parts on the screen surface. Grinding also prepares the screen for subsequent processing steps such as polishing and coating, making it an indispensable step in the production and processing of mobile phone screens.

[0003] When existing grinding equipment grinds mobile phone screens, it usually uses clamping or vacuum suction cups to fix the screen. When using clamping to fix the screen, the clamping device may affect the grinding equipment's processing of the screen. Furthermore, improper clamping design or excessive clamping force may cause damage or deformation to the screen surface. This is especially true for fixing flexible screens, which are generally fixed using vacuum suction cups.

[0004] However, existing grinding equipment uses vacuum adsorption to fix the mobile phone screen. When grinding the mobile phone screen, the screen is prone to movement due to excessive grinding speed or excessive grinding pressure. In addition, existing grinding equipment uses grinding fluid to wash the screen, and the waste particles generated during grinding are not completely washed away, which can easily cause scratches on the mobile phone screen. Summary of the Invention

[0005] This application proposes a grinding device for mobile phone screen processing. When the mobile phone screen is fixed by using a vacuum suction cup to adsorb it, the mobile phone screen is not easy to move, and the waste generated by grinding is not likely to cause scratches to the mobile phone screen. This solves the problems of existing grinding equipment for grinding mobile phone screens, which are prone to screen movement due to grinding pressure and screen scratches caused by grinding waste.

[0006] To achieve the above objectives, this application adopts the following technical solution: a grinding device for processing mobile phone screens, comprising a processing tank containing grinding fluid, and a first grinding device and a second grinding device disposed within the processing tank.

[0007] The grinding device includes a rotating shaft on which a plurality of grinding rollers are mounted at equal intervals. The positions of the grinding rollers in the two grinding devices correspond one-to-one, and the two grinding rollers at corresponding positions in the two grinding devices grind a mobile phone screen at the same time. The two grinding rollers grinding a mobile phone screen rotate in opposite directions, and the grinding liquid in the processing tank immerses the mobile phone screen being ground.

[0008] It also includes a transfer device for transferring mobile phone screens. Two lifting hydraulic cylinders are fixedly installed on the transfer device. The piston shafts of the two lifting hydraulic cylinders are connected to a passive beam. Several vacuum adsorption devices are arranged at equal intervals at the bottom of the passive beam. The vacuum adsorption devices are used to adsorb mobile phone screens.

[0009] Furthermore, the processing tank includes a base and a surrounding plate. The surrounding plate is fixedly installed on the top of the base. Both sides of the bottom of the base are connected to liquid guide pipes. One liquid guide pipe adds grinding liquid to the inside of the surrounding plate, and the other liquid guide pipe discharges grinding liquid.

[0010] Furthermore, a support plate is fixedly installed inside the processing tank. There are two support plates, which are respectively located on both sides inside the processing tank, and two grinding devices are arranged between the two support plates.

[0011] Furthermore, a number of equidistant positioning sleeves are mounted on the rotating shaft via bearings, and each positioning sleeve has a sealing sleeve at both ends to seal the bearing between the inner side of the positioning sleeve and the outer side of the rotating shaft. Grinding rollers are provided on both sides of the positioning sleeve.

[0012] Furthermore, a positioning block is fixedly installed on the outer side of the positioning sleeve. The top and bottom of the positioning block are provided with grooves perpendicular to the rotation axis. Positioning shafts are movably fitted on the two grooves respectively. Both ends of the positioning shafts are movably connected to the inner wall of the processing groove. The positioning shafts limit the positioning on the upper and lower sides of the positioning block to ensure that the positioning block, positioning sleeve, rotation axis and grinding roller in the two grinding devices always maintain a stable horizontal state, thereby improving the stability of the device.

[0013] Furthermore, in the first grinding device, both ends of the rotating shaft are fixedly installed to the two support plates via bearings. A first motor that drives the rotating shaft in the first grinding device to rotate is fixedly installed on one of the support plates, and a limiting sleeve that is movably fitted to the other end of the rotating shaft in the first grinding device is fixedly installed on the other support plate. Both support plates are provided with sliding grooves. In the second grinding device, both ends of the rotating shaft are respectively equipped with sliding sleeves via bearings, and the two sliding sleeves at both ends of the rotating shaft are movably fitted to the sliding grooves on the two support plates. A baffle is fixedly fitted on the outer side of one of the sliding sleeves, and the baffle is movably connected to the outer side of one of the support plates. A second motor is fixedly installed on the outer side of the other sliding sleeve, and the second motor is movably connected to the outer side of the other support plate. The second motor drives the rotating shaft in the second grinding device to rotate. The inner sides of both support plates are provided with adjusting devices that push the second grinding device toward or away from the first grinding device.

[0014] Furthermore, the adjusting device includes two L-shaped plates fixedly installed inside the support plate. The two L-shaped plates are located on the upper and lower sides of the rotating shaft. A slider is movably fitted between the two L-shaped plates. The slider is movably fitted on the outside of the rotating shaft. A limiting block is fixedly installed at one end of each of the two L-shaped plates. An adjusting hydraulic cylinder is fixedly installed on the side of the limiting block away from the slider. The piston shaft of the adjusting hydraulic cylinder passes through the limiting block and is connected to a linkage sleeve. The side of the linkage sleeve away from the piston shaft of the adjusting hydraulic cylinder is fixedly connected to one side of the slider.

[0015] Furthermore, the slider and the rotating shaft, as well as the adjusting hydraulic cylinder and the linkage sleeve, are all connected by bearings, and the connection between the rotating shaft and the slider, and the connection between the adjusting hydraulic cylinder and the linkage sleeve are respectively provided with sealing rings to seal the bearings.

[0016] Furthermore, the transfer device includes two hollow beams, with three sets of carrier plates fixedly installed between the two hollow beams. Each set of carrier plates consists of two plates, and each set of carrier plates is located on the upper and lower sides of the hollow beam. One set of carrier plates is located in the middle of the two hollow beams, and a passive block is fixedly installed on one of the carrier plates located in the middle of the two hollow beams. A lead screw is threaded into the middle of the passive block, and two limit rods are movably mounted on the passive block, located on both sides of the passive block. The other two sets of carrier plates are located at both ends of the hollow beams, and a lifting hydraulic cylinder is fixedly installed on one of the carrier plates located at both ends of the two hollow beams.

[0017] Furthermore, the vacuum adsorption device includes a mounting plate fixedly installed at the bottom of the passive beam. A fixing box is fixedly installed at the bottom of the mounting plate. At least two positioning connecting pipes are fixedly installed at the bottom of the fixing box. A suction cup is fixedly installed at the bottom end of the positioning connecting pipe. An air guiding hose is connected between two adjacent fixing boxes. An air supply hose is connected to the outside of one of the fixing boxes. One end of the air supply hose is connected to a negative pressure pump. The air supply hose, the air guiding hose, and the positioning connecting pipe are connected in a continuous manner.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. This application provides a grinding device for mobile phone screen processing. By setting two grinding devices in the processing tank, the positions of the grinding rollers in the two grinding devices for grinding the mobile phone screen are one-to-one, and the two grinding rollers for grinding the mobile phone screen rotate in opposite directions. This allows the forces exerted on the mobile phone screen by the two grinding rollers during grinding to cancel each other out, which facilitates stable fixation of the mobile phone screen during grinding. Compared with existing grinding equipment that uses vacuum adsorption to fix the mobile phone screen, this effectively reduces the possibility of screen movement caused by excessive grinding speed or excessive grinding pressure during grinding, thereby ensuring the quality of mobile phone screen grinding.

[0020] 2. The present application provides a grinding device for mobile phone screen processing, which simultaneously grinds a mobile phone screen by two grinding rollers at corresponding positions in two grinding devices, thereby improving the grinding efficiency of a single mobile phone screen. Furthermore, the grinding rollers used for grinding mobile phone screens are set in multiple groups, which can grind multiple mobile phone screens at the same time, further improving the processing efficiency of mobile phone screens.

[0021] 3. The grinding apparatus for mobile phone screen processing provided in this application uses a grinding roller in a processing tank to grind the mobile phone screen from below. The grinding liquid in the processing tank immerses the mobile phone screen being ground, ensuring full contact between the screen surface to be processed and the grinding liquid. This facilitates full utilization of the grinding liquid, promotes uniform grinding of the screen, and improves the grinding effect. Furthermore, by completely immersing the screen surface in the grinding liquid, and with the addition of a circulation system, compared to existing grinding equipment that uses grinding liquid rinsing, this effectively avoids the problem of incomplete rinsing of grinding debris particles, which can easily cause scratches on the screen. This improves the grinding quality of the mobile phone screen and reduces the driving energy consumption of grinding liquid rinsing. Attached Figure Description

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] like Figures 1-2 A grinding apparatus for mobile phone screen processing includes a processing tank containing grinding fluid and a transfer device for transferring mobile phone screens for grinding. The processing tank includes a base 1 and a surrounding plate 2. The surrounding plate 2 is fixedly installed on the top of the base 1. Both sides of the bottom of the base 1 are connected to liquid guide pipes 3. One liquid guide pipe 3 adds grinding fluid to the inside of the surrounding plate 2, and the other liquid guide pipe 3 discharges grinding fluid, so as to circulate and dissipate heat and filter impurities in the grinding fluid. The specific circulation system and filtration structure can use existing publicly available technologies, which will not be described in detail here. This allows the grinding fluid to be used for lubrication, cooling and cleaning during the mass production grinding of mobile phone screens, so as to ensure the grinding quality of mobile phone screens.

[0037] Two support plates 4 are fixedly installed inside the processing groove. The two support plates 4 are located on opposite sides inside the processing groove, and both support plates 4 are fixed to the top of the base 1 by L-shaped fasteners. (See [link to relevant documentation]). Figures 2-5 Two grinding devices are provided between the two support plates 4, namely the first grinding device and the second grinding device. The grinding device includes a rotating shaft 5, on which a number of equidistantly arranged positioning sleeves 6 are mounted via bearings. Each positioning sleeve 6 has a sealing sleeve at both ends to seal the bearing between the inner side of the positioning sleeve 6 and the outer side of the rotating shaft 5. Grinding rollers 7 are mounted on the rotating shaft 5 on both sides of the positioning sleeves 6. The positions of the grinding rollers 7 in the two grinding devices correspond one-to-one, and the two grinding rollers 7 at corresponding positions in the two grinding devices grind a mobile phone screen at the same time. This allows the two grinding devices to process multiple mobile phone screens at the same time, improving the efficiency of mobile phone screen grinding. At the same time, by controlling the rotation direction of the two grinding rollers 7 to be opposite, the forces exerted on the mobile phone screen by the two grinding rollers 7 during grinding can cancel each other out, which facilitates stable fixation of the mobile phone screen during grinding.

[0038] A positioning block 8 is fixedly installed on the outer side of the positioning sleeve 6. The top and bottom of the positioning block 8 are provided with grooves perpendicular to the rotating shaft 5. Positioning shafts 9 are movably fitted on the two grooves respectively. Both ends of the positioning shafts 9 are movably connected to the inner wall of the surrounding plate 2. The positioning shafts 9 limit the positioning on the upper and lower sides of the positioning block 8 to ensure that the positioning block 8, positioning sleeve 6, rotating shaft 5 and grinding roller 7 in the two grinding devices always maintain a stable horizontal state, thereby improving the stability of the device.

[0039] Please continue reading. Figure 4 , Figures 6-8 In the first grinding device, both ends of the rotating shaft 5 are fixedly installed between the two support plates 4 via bearings. A first motor 10 that drives the rotating shaft 5 in the first grinding device to rotate is fixedly installed on one of the support plates 4, and a limiting sleeve 11 that is movably connected to the other end of the rotating shaft 5 in the first grinding device is fixedly installed on the other support plate 4. A sealing ring is provided at the connection between the limiting sleeve 11 and the rotating shaft 5 to seal the connection, so that the first grinding device is fixedly installed between the two support plates 4.

[0040] Both support plates 4 are provided with sliding grooves 401. Sliding sleeves 12 are mounted on both ends of the rotating shaft 5 in the second grinding device via bearings. The two sliding sleeves 12 at both ends of the rotating shaft 5 are movably engaged with the sliding grooves 401 on the two support plates 4, allowing the two sliding sleeves 12 to move along the sliding grooves 401 on the two support plates 4 towards or away from the first grinding device. This, in turn, allows the second grinding device to move towards or away from the first grinding device, adjusting the distance between the two grinding rollers 7 at corresponding positions in the second and first grinding devices. This distance is half the length of the mobile phone screen, allowing for grinding according to different screen sizes. When grinding begins, the grinding roller 7 in one grinding device grinds from one end of the mobile phone screen, while the grinding roller 7 in the other grinding device grinds from the middle of the mobile phone screen. A baffle 13 is fixedly fitted on the outer side of one sliding sleeve 12, and the baffle 13 is movably connected to the outer side of one support plate 4. A second motor 14 is fixedly installed on the outer side of the other sliding sleeve 12, and the second motor 14 is movably connected to the outer side of the other support plate 4. The second motor 14 drives the rotating shaft 5 in the second grinding device to rotate. The inner sides of both support plates 4 are provided with adjustment devices that push the second grinding device toward or away from the first grinding device.

[0041] The adjustment device includes two L-shaped plates 15 fixedly installed inside the support plate 4. The two L-shaped plates 15 are located on the upper and lower sides of the rotating shaft 5. A slider 16 is movably fitted between the two L-shaped plates 15. The slider 16 is movably fitted on the outside of the rotating shaft 5, and a bearing is provided between the slider 16 and the rotating shaft 5. A limiting block 17 is fixedly installed at one end of the two L-shaped plates 15. An adjustment hydraulic cylinder 18 is fixedly installed on the side of the limiting block 17 away from the slider 16. The piston shaft of the adjustment hydraulic cylinder 18 passes through the limiting block 17 and is connected to a linkage sleeve 19. The linkage sleeve 19 is away from the adjustment hydraulic cylinder. One side of the piston shaft of the pressure cylinder 18 is fixedly connected to one side of the slider 16. The piston shaft is driven by the adjusting hydraulic cylinder 18 to push the linkage sleeve 19, slider 16, rotating shaft 5 and grinding roller 7 to move as a whole. The two adjusting hydraulic cylinders 18 are used to control the spacing value of the two grinding rollers 7 at corresponding positions in the second grinding device and the first grinding device. The adjusting hydraulic cylinder 18 and the linkage sleeve 19 are connected by bearings. The connection between the rotating shaft 5 and the slider 16 and the connection between the adjusting hydraulic cylinder 18 and the linkage sleeve 19 are respectively provided with sealing rings to seal the bearings.

[0042] Please continue reading. Figures 2-3The transfer device includes two hollow beams 20, with three sets of carrier plates 21 fixedly installed between them. Each set of carrier plates 21 consists of two plates, located on the upper and lower sides of each hollow beam 20 and secured to it with bolts and nuts. One set of carrier plates 21 is positioned in the middle of the two hollow beams 20, and a passive block 22 is fixedly installed on one of the carrier plates 21 located in the middle of the two hollow beams 20. A lead screw 23 is threaded into the middle of the passive block 22, and the lead screw 23 drives the movement of the passive block 22 via a motor (this is existing technology and will not be described in detail here). The diagram does not show the motor that drives the lead screw to rotate, nor the fixing structures at both ends of the lead screw. The drive rotates, thereby controlling the passive block 22 to move the two hollow beams 20 and the three sets of carrier plates 21 along the lead screw 23. Two limiting rods 24 are movably mounted on the passive block 22, and the two limiting rods 24 are respectively located on both sides of the passive block 22. The other two sets of carrier plates 21 are respectively located at both ends of the hollow beams 20. A lifting hydraulic cylinder 25 is fixedly installed on one of the carrier plates 21 located at both ends of the two hollow beams 20. The piston shafts of the two lifting hydraulic cylinders 25 are fixedly installed on the passive beam 26. Several vacuum adsorption devices are arranged at equal intervals at the bottom of the passive beam 26.

[0043] Please see Figure 9 The vacuum adsorption device includes a mounting plate 27 fixedly installed at the bottom of the passive beam 26. A fixing box 28 is fixedly installed at the bottom of the mounting plate 27. At least two positioning connecting pipes 29 are fixedly installed at the bottom of the fixing box 28. A suction cup 30 is fixedly installed at the bottom end of the positioning connecting pipe 29. A gas guiding hose 31 is connected between two adjacent fixing boxes 28. A gas supply hose 32 is connected to the outside of one of the fixing boxes 28. One end of the gas supply hose 32 is connected to a negative pressure pump (the negative pressure pump is a prior art and is not shown in the figure). The gas supply hose 32, the gas guiding hose 31, and the positioning connecting pipe 29 are connected in a continuous manner.

[0044] In use, to process the desired size of the mobile phone screen, the adjusting hydraulic cylinders 18 on the two support plates 4 simultaneously drive the piston shaft to move, adjusting the position in the second grinding device so that the distance between the two grinding rollers 7 at corresponding positions in the two grinding devices is half the length of the mobile phone screen. The mobile phone screen is then adsorbed by the suction cups 30 in the vacuum adsorption device. The transfer device moves the vacuum adsorption device and the mobile phone screen together above the two grinding devices, positioning the center of the mobile phone screen directly above the grinding rollers 7 in the first grinding device. The lifting hydraulic cylinder 25 is then activated to drive the piston shaft to move, pushing the passive beam 26 to lower the vacuum adsorption device, causing the mobile phone screen adsorbed by the suction cups 30 in the vacuum adsorption device to adhere to the grinding rollers 7 in the first grinding device. Figure 1As shown, the grinding liquid in the processing tank completely submerges the mobile phone screen to be processed. The first motor 10 drives the grinding roller 7 in the first grinding device to rotate, and the second motor 14 drives the grinding roller 7 in the second grinding device to rotate in the opposite direction. Simultaneously, the vacuum adsorption device moves the mobile phone screen from the first grinding device towards the second grinding device. By utilizing the counter-rotating grinding rollers 7 in the two grinding devices, the mobile phone screen is simultaneously ground until... Figure 11 As shown in the image, grinding of a single mobile phone screen is now complete.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
