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.

These terms are used solely for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," etc., are only used to distinguish multiple components or structures with the same or similar structures and do not indicate any special limitation on the arrangement order or connection relationship.

[0029] Please refer to Figures 1 to 4This invention provides a vertical cleaning and grinding device, comprising: a first mounting base 110, a vertical mounting assembly, a rotating device, and a grinding assembly; the vertical mounting assembly is disposed on the first mounting base 110 and includes a positioning assembly for positioning and assembling a display screen; the rotating device includes a first drive assembly 131 and a first mounting frame 132 disposed on the top of the first mounting base 110 and rotatably connected to the first mounting base 110, the vertical mounting assembly being disposed on the top of the first mounting frame 132, and the first drive assembly 131 driving the first mounting frame to rotate; the grinding assembly includes a second mounting base 141, a second mounting frame 142 disposed on the top of the second mounting base 141, a grinding head 143 slidably disposed on the top of the second mounting frame 142, a second drive assembly 144 for driving the grinding head 143 to rotate and grind, and a third drive assembly 145 for driving the second mounting frame 142 to slide. Further, the first mounting base 110 refers to a base structure for supporting and fixing other components, specifically made of metal or engineering plastic, serving to support the vertical mounting assembly, the rotating device, and the grinding assembly. The vertical mounting assembly can specifically employ a bracket with positioning grooves and an adsorption device to fix the display screen in a vertical position and maintain its stable position, avoiding polishing slurry residue that would occur with horizontal placement. The rotating device refers to the combination structure of the drive assembly and the rotating bracket. Specifically, it can use a motor or cylinder in conjunction with a rotating shaft to achieve rotation, allowing the vertical mounting assembly to rotate around the axis, facilitating adjustment of the display screen angle to adapt to different polishing requirements. The polishing assembly is an integrated module containing a polishing head 143, a drive unit, and a sliding mechanism. Specifically, it can use an electric slide rail in conjunction with a servo motor to control the movement path of the polishing head 143, combining vertical sliding and rotary polishing actions to improve surface finish and reduce secondary contamination.

[0030] This application uses a vertical mounting component to fix the display screen vertically, combined with a rotating device to adjust the workpiece angle, and with the multi-directional motion control of the grinding component, to achieve a vertical posture of the workpiece during the grinding process. The grinding fluid and water flow into the receiving tank 122 by gravity, effectively avoiding the problems of grinding fluid retention and surface contamination, and improving processing efficiency and finished product quality.

[0031] In this embodiment, the positioning component includes a receiving groove 122 disposed on the top of the first mounting bracket 132. The receiving groove 122 contains a plurality of suction nozzles 123 for adsorbing the display screen. At least two positioning blocks 124 are also disposed on the top of the first mounting bracket 132, and an adsorption plate 125 for cooperating with the suction nozzles 123 to adsorb the display screen is disposed between the two positioning blocks 124. Further, the receiving groove 122 is located in the top planar area of ​​the mounting bracket, and the number of suction nozzles 123 is four or more, evenly distributed on the bottom surface of the receiving groove 122, and connected to an external negative pressure device via a vacuum pipeline. The positioning blocks 124 are made of hard alloy material and are symmetrically distributed perpendicular to the edge of the receiving groove 122, with a distance between them slightly greater than the length of the display screen. The adsorption plate 125 is made of porous ceramic material, with a surface covered by an elastic silicone layer, and overlaps with the adsorption area of ​​the suction nozzles 123.

[0032] Specifically, when the display screen is placed in the receiving slot 122, its edges are blocked by the positioning block 124, and the limiting protrusion 126 abuts against the side of the display screen. At this time, the suction nozzle 123 is activated to generate negative pressure, adsorbing and fixing the bottom surface of the display screen. The adsorption plate 125 transmits the negative pressure evenly to the surface of the display screen through its porous structure. The elastic silicone layer fills the microscopic gap between the display screen and the adsorption plate 125 to avoid local pressure concentration. The combined action of the positioning block 124 and the adsorption plate 125 keeps the display screen stable during rotation, ensuring adsorption stability.

[0033] In this embodiment, three positioning blocks 124 are provided. Each positioning block 124 has a limiting protrusion 126 on its top. The display screen is positioned between the three positioning blocks 124. The limiting protrusion 126 restricts the displacement of the display screen, and one end of the display screen extends to the top of the suction nozzle 123. Furthermore, the three positioning blocks 124 are arranged in a triangular pattern to form a stable support structure. The limiting protrusion 126 is a square protrusion structure. A buffer layer with a thickness of 0.1-0.3 mm is provided in the contact area between the display screen and the positioning blocks 124.

[0034] Specifically, when the display screen is placed in the triangular support area formed by the three positioning blocks 124, the limiting protrusions 126 constrain the displacement of the display screen in both the planar and vertical directions. The contact surface between the edge of the display screen and the limiting protrusions 126 forms a three-point limit. When the first mounting bracket 132 rotates, the triangularly distributed positioning blocks 124 can counteract inertial forces in different directions. When one end of the display screen extends to the top area of ​​the suction nozzle 123, the negative pressure suction force generated by the suction nozzle 123 and the mechanical limiting of the limiting protrusions 126 form a double fixation.

[0035] In this embodiment, the rotating device includes a rotating shaft 133 and rotating seats 134 disposed on both sides of the top of the first mounting base 110. The rotating shaft 133 and the rotating seats 134 are rotatably connected by bearings and bearing seats. The first mounting bracket 132 is fixed on the rotating shaft 133. A first drive assembly 131 for driving the rotating shaft 133 to rotate is disposed between the two rotating seats 134. Further, the rotating seats 134 are disposed on both sides of the top of the mounting base to form a symmetrical support structure. The rotating shaft 133 is connected to the rotating seats 134 through bearings and bearing seats. The inner ring of the bearing is interference-fitted with the rotating shaft 133, and the outer ring of the bearing is fixedly connected to the bearing seat. The first drive assembly 131 is linked to the rotating shaft 133 through gears or belts, and the output end of the drive assembly is located between the two rotating seats 134.

[0036] Specifically, the bearing housing is bolted to the rotating base 134, and the mounting bracket is fixed to the middle of the rotating shaft 133 by welding or interference fit. The first drive assembly 131 is connected to the rotating shaft 133 via a coupling or by gear meshing to transmit torque. The centrally positioned first drive assembly 131 ensures a symmetrical power transmission path, preventing the rotating shaft 133 from bending due to unilateral force. Therefore, the rotating device can maintain smooth rotation when driving the mounting bracket, reducing vibration and offset, and improving grinding accuracy and equipment stability. Furthermore, the first drive assembly 131 can be a cylinder or a motor.

[0037] In this embodiment, the first mounting base 110 includes a base body, the top of which is provided with a receiving groove 138. A first electric slide rail 150 is disposed within the receiving groove 138, and a first sliding seat 151 is disposed on the first electric slide rail 150. A U-shaped connecting block 137 is disposed at the bottom of the first mounting frame 132. One end of the U-shaped connecting block 137 is connected to the bottom of the first mounting frame 132, and the other end passes through the bottom of the receiving groove 138 and is connected to the first sliding seat 151. Furthermore, the base body serves as a supporting foundation, the receiving groove 138 provides installation space for the first electric slide rail 150, the first electric slide rail 150 achieves linear motion control via electric drive, and the first sliding seat 151 slides along the track of the first electric slide rail 150 and forms a rigid connection with the first mounting frame 132 through the U-shaped connecting block 137. One end of the U-shaped connecting block 137 is fixed to the bottom of the first mounting bracket 132, and the other end extends to the bottom of the receiving slot 138 and is fixed to the first sliding seat 151 to form a bridging structure.

[0038] In this embodiment, a waterproof cover plate (not shown in the figure) is provided on the top of the receiving channel 138. Furthermore, the waterproof cover plate covers the opening of the receiving channel 138, and its edge forms a sealed connection with the top edge of the receiving channel 138. The waterproof cover plate is made of corrosion-resistant metal or engineering plastic and is detachably connected to the top of the channel by bolts or a snap-fit ​​structure. The width of the waterproof cover plate is greater than the opening width of the receiving channel 138 to ensure complete coverage of the top area of ​​the channel.

[0039] Specifically, the waterproof cover extends along the length of the receiving groove 138, covering the entire groove opening. The waterproof cover continuously prevents external liquids and particles from entering the groove. When grinding fluid splashes or cleaning water flows across the mounting surface during the grinding process, the waterproof cover physically prevents liquid from seeping into the groove, thus preventing the first electric slide rail 150 from contacting the sliding seat and causing corrosion or jamming. This structure improves the equipment's sealing performance by adding independent protective components, ensuring the long-term stable operation of the electric slide rail system in humid environments.

[0040] In this embodiment, a second electric slide rail 170 is provided on the top of the second mounting base 141, a second sliding seat 171 is provided on the second electric slide rail 170, and a second mounting bracket 142 is disposed on the second sliding seat 171. The third drive assembly 145 is a drive motor, which drives the second mounting bracket 142 to slide on the second electric slide rail 170. Further, the second electric slide rail 170 is a linear guide rail structure, and the second sliding seat 171 achieves linear movement through a slider cooperating with the guide rail. The drive motor is connected to the second sliding seat 171 through a coupling or transmission mechanism, converting rotational motion into linear displacement. The second mounting bracket 142 is fixed to the second sliding seat 171 by bolts or clips and moves synchronously with the sliding seat.

[0041] In this embodiment, the grinding head 143 includes a head 143.1 and a rod 143.2 that is linked to the drive end of the second drive assembly 144. A linkage gear 147 is provided at the end of the rod 143.2 away from the head 143.1. The linkage gear 147 is connected to the drive end of the second drive assembly 144 through a transmission belt 148.

[0042] In this embodiment, a waterproof upright plate 180 is provided on the top of the second mounting base 141. The waterproof upright plate 180 has a through hole 181 for the rod 143.2 to pass through. An air inlet channel (not shown in the figure) connected to the air inlet pipe is provided on the top of the waterproof upright plate 180. An air outlet (not shown in the figure) is provided on the top of the through hole 181 and communicates with the air inlet channel. The air outlet continuously sprays airflow to prevent water from passing through the through hole 181. An air inlet valve 184 is provided at the inlet of the air inlet channel. Furthermore, the waterproof upright plate 180 is vertically fixed to the top of the second mounting base 141. The diameter of the through hole 181 is slightly larger than the outer diameter of the rod 143.2 to allow the rod 143.2 to rotate freely. The air inlet channel extends longitudinally along the interior of the waterproof upright plate 180, and the air outlets are arranged in a ring around the top edge of the through hole 181. An air pump or compressed air source is connected to the air inlet pipe, and the airflow is evenly distributed to each air outlet through the air inlet channel. When the linkage gear 147 is connected to the transmission belt 148, the airflow continuously forms an annular air curtain during the rotation of the rod 143.2.

[0043] Specifically, when the grinding head 143 rotates for grinding, the drive motor drives the second mounting bracket 142 to move along the second electric slide rail 170, and the rod 143.2 passes through the through hole 181 and is linked with the grinding head 143. The air pump delivers airflow to the air inlet pipe, and the airflow enters the air outlet through the air inlet channel, and is sprayed out in a ring at a certain pressure from the top of the through hole 181. The sprayed airflow forms a dynamic air curtain barrier above the through hole 181, preventing splashed water or grinding liquid from entering the interior of the through hole 181 during the grinding process. When the linkage gear 147 rotates with the rod 143.2, the air curtain can simultaneously cover the gap area between the rod 143.2 and the through hole 181. The waterproof upright plate 180 and the second mounting base 141 form a closed structure, which, together with the air curtain barrier, provides double protection to prevent liquid from seeping into the equipment and causing component corrosion or electrical failure.
