[0030] Currently, the loading and unloading of display screens during edge grinding is achieved by controlling the lifting and lowering settings of the conveyor, thereby improving the loading and unloading efficiency. However, this method of moving the display screen onto the suction cup for support and fixation can easily lead to uneven suction force, causing the display screen to tilt. Furthermore, issues such as aging suction cups, differences in suction force among multiple suction cups, and vacuum pump malfunctions can all cause the display screen to become loose or tilted, thus affecting the edge grinding process. In addition, the frequent up-and-down movement of the conveyor can affect the loading and unloading of the display screen, and frequent lifting and lowering can easily cause the display screen to shift on the conveyor during transport, affecting the accuracy of the edge grinding.

[0031] This utility model provides a glass edging device for display screens, such as... Figure 1As shown, in this embodiment, the display glass edge grinding equipment includes a body 1 and a conveying mechanism 3 and an edge grinding mechanism 2 disposed within the body 1. The bottom of the body 1 is provided with support feet, and inlets and outlets are provided on both sides of the body 1 for the loading and unloading of display glass. The conveying mechanism 3 supports and conveys the display glass, feeding it into the body 1 from one end and sending it out from the other end after edge grinding. In this embodiment, the edge grinding mechanism 2 includes an edge grinding assembly, a horizontal control module for controlling the horizontal multi-directional movement of the edge grinding assembly, and a lifting control module for controlling the lifting motion of the edge grinding assembly. The horizontal control module is configured as a transmission assembly of a lead screw and a motor, and the lifting motion control module can be configured as a cylinder. The edge grinding assembly is used to grind the edges of the display glass. The above structures are all relatively mature existing technologies, and the specific connection and installation details are not elaborated in this application. To meet the requirements of loading and unloading from both ends of the body 1, such as... Figure 2 As shown, the conveying mechanism 3 is configured with both ends extending out of the machine body 1 through its inlet and outlet. The support portion of the conveying mechanism 3 is fixedly installed inside the machine body 1. In this embodiment, the conveying mechanism 3 includes at least a support frame 31, a motor, a drive roller 33, and a conveyor belt 32. The support frame 31 provides support inside the machine body 1, supporting and connecting the drive roller 33 and the motor. The motor controls the drive roller 33 to rotate, driving the conveyor belt 32 to convey the glass. Both the conveyor roller and the conveyor belt 32 are configured as double units, located inside the machine body 1 to support the display screen glass from both sides. A lifting groove is formed between the two conveyor belts 32, and the rotating shafts of the conveyor rollers on both sides are connected by the same motor. The drive ensures the synchronicity of the conveyor belts 32 on both sides; a lifting mechanism 4 is provided inside the machine body 1. The lifting mechanism 4 is located at the bottom of the conveyor mechanism 3, and the lifting mechanism 4 can extend from the lifting groove to the upper end of the conveyor mechanism 3. That is, when working, the lifting mechanism 4 can lift the display glass placed on the conveyor belt 32 to be supported by the lifting mechanism 4 (this action is performed after the conveyor belt 32 stops moving); at the same time, an upper pressure block 5 is fixed inside the machine body 1. The upper pressure block 5 is located at the upper end of the conveyor mechanism 3 and directly above the lifting mechanism 4. The lifting mechanism 4 can cooperate with the upper pressure block 5 to clamp and fix the display glass.

[0032] Based on the above structure, when this utility model is in operation, the display screen glass is first placed on the conveyor belt 32 of the conveying mechanism 3 from one side of the machine body 1. The conveying mechanism 3 starts to convey the display screen glass into the machine body 1. When the display screen glass is conveyed to the bottom of the upper pressure block 5, the conveying stops. The lifting mechanism 4 is started to push the display screen glass upward to the top and press it against the upper pressure block 5. The display screen glass is fixed by the cooperation of the lifting mechanism 4 and the upper pressure block 5. Then the edge grinding mechanism 2 is started to perform edge grinding. After the edge grinding is completed, the lifting mechanism 4 is lowered and the display screen glass returns to the conveyor belt 32 and is supported by the conveyor belt 32. The conveying is started again to transport the display screen glass out of the machine body 1.

[0033] Through the above technical solution, this utility model uses the lifting mechanism 4, which works in conjunction with the upper pressure block 5, to fix the display screen glass. Compared with the prior art, the suction cup adsorption support is replaced with a more stable pushing and clamping method to fix the display screen glass. The fixation of the display screen glass is more stable, avoiding the phenomenon of the display screen glass tilting due to uneven adsorption force when supported by the suction cup, and avoiding the phenomenon of the display screen glass moving during edge grinding due to insufficient adsorption force. This improves the stability of the display screen glass fixation and the accuracy of edge grinding. At the same time, the conveying mechanism 3 is changed to a setting that does not require lifting and conveying, ensuring the stability of the display screen glass loading and unloading, and avoiding the phenomenon of the display screen glass shifting during conveying due to frequent lifting and lowering of the conveying mechanism 3.

[0034] To ensure stability when clamping and fixing the display screen, and to prevent the display glass from being tilted; such as Figure 3 As shown, a pressure plate 6 is set at the bottom of the upper pressure block 5, and a pressure sensor 7 is set between the upper pressure block 5 and the pressure plate 6. Specifically, a pressure sensor 7 is set at each of the four corners of the pressure plate 6, and the four pressure sensors 7 are symmetrically arranged with the pressure plate 6 as the center. At the same time, the edge grinding equipment also includes a control module, which is used to receive the values ​​of each pressure sensor 7 and compare them. Specifically, when the pressure plate 6 is in contact with and fixed to the display glass, the values ​​of each pressure sensor 7 are obtained and compared. When the values ​​of the four pressure sensors 7 are the same, it indicates that the pressure is uniform, and the display glass is in a horizontal and untilted state. When the pressure values ​​of one or more pressure sensors 7 are different, it indicates that the display glass is tilted or the installation of the upper pressure block 5 and the pressure plate 6 is not accurate enough, and timely adjustment is required. At the same time, the setting of the pressure sensor 7 can obtain the clamping pressure on the display in real time, which facilitates timely adjustment of the lifting mechanism 4 and avoids damage to the display glass due to excessive pressure or unstable clamping due to insufficient pressure.

[0035] To ensure the stability of the lifting mechanism 4 in raising and lowering the display screen glass, and to ensure that the display screen is placed horizontally on the lifting mechanism 4; such as Figure 3 and Figure 4 As shown, the lifting mechanism 4 is configured as a horizontal support plate 41, a limiting member 42, and a lifting cylinder 43. The horizontal support plate 41 supports the display screen glass. The limiting member 42 and the lifting cylinder 43 are installed at the inner bottom of the body 1. The output end of the lifting cylinder 43 is connected to the center of the bottom of the horizontal support plate 41, and the lifting cylinder 43 drives the lifting of the machine. A limiting member 42 is connected to both ends of the horizontal support plate 41. Figure 5As shown, the limiting component 42 includes two columns 421, a positioning plate 422 fixed to the bottom of the columns 421, and a connecting plate 423 connected to the horizontal support plate 41; a positioning platform is fixed to the bottom of the machine body 1, and the positioning plate 422 is detachably installed on the positioning platform by screws for positioning; a sliding cavity is opened inside the column 421, the sliding cavity is vertically arranged in an upper strip shape, a sliding groove is opened on the side of the column 421, and a slider 424 that can slide up and down in the sliding cavity is provided in the sliding cavity. The side of the slider 424 is precisely fitted and slids with the slide rail on the inner wall of the sliding cavity. The two ends of the connecting plate 423 are respectively fixedly connected to the slider 424 in the two columns 421; when the lifting cylinder 43 drives the horizontal support plate 41 to rise and fall, the limiting component 42 limits the two sides of the horizontal support plate 41 to ensure the stability of the horizontal support plate 41 and prevent the horizontal support plate 41 from tilting when rising and falling.

[0036] To ensure the horizontal stability of the horizontal support plate 41 during installation, a level sensor is installed on the horizontal support plate 41 to detect its levelness after installation and during subsequent use. Meanwhile, the connecting plate 423 and the horizontal support plate 41 are designed for detachable connection, specifically a screw connection. A limiting groove 425 is provided on the top of the connecting plate 423 for placing one end of the horizontal support plate 41, which limits the installation on both sides of the horizontal support plate 41, ensuring installation accuracy. The detachable design also facilitates replacement of the horizontal support plate 41.

[0037] To further ensure the horizontal support plate 41 is level and prevent tilting when supporting the display screen glass, position sensors 426 are installed at the bottom of the sliders 424. The position sensors 426 of the four sliders 424 are all connected to the control module. The control module acquires the position information of the four position sensors 426 when the horizontal support plate 41 is raised or lowered. When the heights of the four position sensors 426 are consistent, it means that the heights of the four sliders 424 are consistent, which means that the horizontal support plate 41 is level. If the position information of the second horizontal sensor is inconsistent, the horizontal support plate 41 may be tilted, and the lifting mechanism 4 needs to be inspected. The multiple level sensor settings can ensure that the display screen glass is placed horizontally and improve the edge grinding accuracy.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
