[0037] As shown in the accompanying drawings, a screen glass grinding device according to a specific embodiment of the present invention comprises:

[0038] A load-bearing bracket 110;

[0039] A grinding mechanism 120 for grinding the screen glass, the grinding mechanism 120 is mounted on the supporting bracket 110, the grinding mechanism 120 comprises a plurality of grinding modules, the grinding modules comprise a driver 121, a transmission mechanism and a plurality of grinding heads 125, the driver 121 and the grinding heads 125 are mounted on the supporting bracket 110, the transmission mechanism is used for transmission connection between the driver 121 and the grinding heads 125;

[0040] A conveying mechanism 130 for conveying the screen glass, the conveying mechanism 130 comprising a driving assembly 134 and a conveying belt 131, the driving assembly 134 being mounted on the supporting bracket 110, the conveying belt 131 being in transmission connection with the driving assembly 134, and the conveying belt 131 being arranged in a closed loop;

[0041] A plurality of adsorption components 132 are used to place and position the screen glass. The plurality of adsorption components 132 are fixedly mounted on the conveyor belt 131. The driving component 134 drives the conveyor belt 131 to move. The conveyor belt 131 drives the plurality of adsorption components 132 to move synchronously in a closed loop.

[0042] Exemplarily, the support bracket 110 serves as the supporting body of the screen glass polishing device 100, and the other components are mounted on the support bracket 110. The conveying mechanism 130 includes a conveyor belt 131, and the closed-loop setting of the conveyor belt 131 drives multiple adsorption components 132 to move synchronously in a closed loop. Such a structural design can realize the circulation of multiple screen glasses while linearly conveying the screen glass, thereby improving the working efficiency of the polishing equipment and realizing automated production processing.

[0043] In this embodiment, specifically, Figure 1 and Figure 2 As shown, the transmission mechanism includes a plurality of transmission chains 124 and a plurality of transmission shafts 122, wherein the plurality of transmission shafts 122 are rotatably mounted on the support bracket 110, and a transmission sprocket 123 is disposed on the transmission shaft 122, and the transmission sprockets 123 are transmitted through the transmission chain 124, wherein, specifically, Figure 1 As shown, there are multiple rows of transmission shafts, each row has 3 shafts, and each row of transmission shafts is driven to rotate by a driver. The specific arrangement of the driver is shown in the figure.

[0044] like Figure 1 , Figure 3 As shown, as an embodiment, the conveyor belt 131 includes two conveying parts 1311 and two arc transition parts 1312, the conveying parts 1311 are plate-shaped, the arc transition parts 1312 are semicircular, and the conveying parts 1311 and the arc transition parts 1312 are sequentially connected at intervals to enclose a closed loop. Exemplarily, the conveyor belt 131 is in a long trough-shaped closed loop. In this embodiment, the conveyor belt 131 is a belt, that is, the conveying mechanism 130 of this embodiment is actually a belt transmission mechanism.

[0045] like Figure 1 , Figure 3 As shown, as an implementation, two drive assemblies 134 are provided, and the two drive assemblies 134 are respectively connected to the two arc transition parts 1312. For example, in this embodiment, the drive assembly 134 is a servo motor, and the servo motor can accurately control the distance of advancement, because the conveying mechanism 130 must be able to control the distance well and accurately transport the screen glass on the conveyor belt 131 to the bottom of the polishing mechanism 120, so it is necessary to control the distance of advancement of the conveyor belt 131 well.

[0046] like Figure 1 , Figure 3As shown, as an embodiment, the adsorption component 132 is circular, and the length of the arc transition portion 1312 along the second direction is greater than the diameter of the adsorption component 132, and the second direction is perpendicular to the first direction. For example, in this embodiment, the adsorption components 132 are circular, and their diameters can be equal. In addition, the circular structure will leave gaps when each adsorption component 132 is laid on the conveying mechanism 130, so that the water spraying mechanism 140 arranged at the lower end of the adsorption component 132 can pass the sprayed liquid through the gap to the screen glass for cooling and cleaning. It should be noted that the reason why the length of the arc transition portion 1312 along the second direction is greater than the diameter of the adsorption component 132 is to enable the adsorption component 132 located at the upper end of the conveying portion 1311 to move to the lower end of the conveying portion 1311 through the arc transition portion 1312, and then move back to the upper end of the conveying portion 1311. In this way, the circular motion of the adsorption component 132 is realized.

[0047] like Figure 1 , Figure 3 As shown, as an embodiment, a plurality of adsorption components 132 are arranged in multiple rows and columns and are spaced and distributed on the conveyor belt 131. For example, in this embodiment, a plurality of adsorption discs 1322 are spaced and distributed in multiple rows and five columns on the conveyor belt 131, wherein the conveyor belt 131 is a closed-loop long trough structure, that is, the middle section is rectangular, and the two short sides are replaced by semicircles, and the adsorption discs 1322 are small in size, and attached to the conveyor belt 131, the conveyor belt 131 can be rotated with a smaller rotation diameter.

[0048] like Figure 1 , Figure 3 As shown, as an embodiment, the conveying mechanism 130 also includes a plurality of mounting plates 133, which are sequentially arranged on the conveyor belt 131 at intervals, and the adsorption assembly 132 is mounted on the mounting plates 133. By way of example, in this embodiment, the mounting plates 133 are made of metal. Of course, in a specific application, the mounting plates 133 can also be made of non-flexible materials. The function of the mounting plates 133 is to fix the adsorption assembly 132. It should be noted that the mounting plates 133 are rectangular, and the width of the mounting plates 133 should be about the same as the size of the adsorption assembly 132, while the conveyor belt 131 is made of flexible materials such as rubber. The purpose of this is that, on the one hand, the adsorption assembly 132 can be fixed on the conveyor belt 131 through the mounting plates 133, and on the other hand, the mounting plates 133 and the adsorption assembly 132 on the mounting plates 133 can pass over the arc transition portion 1312, thereby realizing rotation.

[0049] like Fig. 9 , Fig.10As shown, as an embodiment, the screen glass grinding device 100 also includes a power assembly 190, and the adsorption assembly 132 has a through slot 1321A. The power assembly 190 is connected to the through slot 1321A, and the top of the through slot 1321A is used to place the screen glass. Exemplarily, the adsorption assembly 132 includes a base 1321 and an adsorption plate 1322, and the adsorption plate 1322 is rotatably mounted on the base 1321. Exemplarily, the adsorption plate 1322 is used to place and position the screen glass, and the adsorption plate 1322 and the base 1321 can rotate relative to each other. Since the grinding head of the present application grinds the screen glass by rotating, the screen glass on the adsorption plate 1322 will also rotate during the grinding process. This is beneficial to the all-round grinding of the screen glass on the one hand, avoiding the situation that some parts cannot be polished. On the other hand, during the grinding process, the screen glass rotates along the direction of rotation of the grinding head, which can avoid the rigid collision between the screen glass and the grinding head, resulting in damage to the screen glass or the grinding head. In addition, it should be noted that during the polishing process, the rotation of the screen glass and the polishing head are not synchronized.

[0050] like Fig. 9 , Fig.10 As shown, as an embodiment, the adsorption plate 1322 is provided with an adsorption slot 1322A, the base 1321 has a through slot 1321A, the through slot 1321A is connected to the adsorption slot 1322A and is sealed, and the screen glass polishing device 100 also includes a power assembly 190 for providing vacuum negative pressure, and the power assembly 190 is connected to the through slot 1321A. Exemplarily, specifically, in this embodiment, the adsorption slot 1322A is composed of a plurality of strip slots laid on the adsorption plate 1322, and the basic shape is a "king" shape composed of three horizontal strip slots and one vertical strip slot, and then the vertical strip slots are connected to the two ends of the three horizontal strip slots. It is equivalent to saying that the adsorption slot 1322A is laid on the adsorption plate 1322, and the purpose of such a structural design is to adapt to screen glasses of various shapes, such as screen glass of mobile phones, tempered films, or screen glasses of various sizes such as display screens of other electronic products. Of course, in specific applications, the shape of the adsorption slot 1322A is not limited to this, and can also be other shapes, and no excessive restrictions are made here. In addition, it should be noted that the adsorption plate 1322 of the present application is equivalent to a mold, which can be replaced and reused according to needs, rather than only fixing a certain specification of adsorption plate 1322 or using it once. The adsorption plate 1322 and the base body 1321 are sealed and connected. The power assembly 190 includes a vacuum pump and a pipeline. The pipeline is connected between the vacuum pump and the through groove 1321A. The power assembly 190 is installed on the supporting bracket 110, and the vacuum pump provides negative pressure to adsorb the screen glass.

[0051] like Fig. 9 , Fig.10 As shown, as an embodiment, the adsorption assembly 132 also includes a bearing (not shown in the figure), and the seat body 1321 is rotatably connected to the adsorption plate 1322 via the bearing. Exemplarily, in this embodiment, the seat body 1321 and the adsorption plate 1322 are rotatably connected via a bearing. Since the force between the grinding head of the grinding mechanism 120 and the screen glass is relatively large during the grinding process of the screen glass by the grinding mechanism 120, and as mentioned above, the screen glass needs to rotate during grinding, the seat body 1321 and the adsorption plate 1322 reduce the friction by setting a bearing, so that the adsorption plate 1322 can more easily rotate relative to the seat body 1321.

[0052] like Fig. 9 , Fig.10 As shown, as an embodiment, the adsorption plate 1322 includes a connecting portion 1322B and a placing portion 1322C, and the placing portion 1322C is connected to the base body 1321 through the connecting portion 1322B. For example, in this embodiment, the placing portion 1322C is rectangular and is a bearing platform for placing the screen glass. Of course, the shape of the placing portion 1322C is not limited to this. For example, it can also be circular, and no excessive restrictions are made here. The placing portion 1322C is arranged at one end away from the base body 1321. The connecting portion 1322B is a component that connects the placing portion 1322C and the base body 1321. The connecting portion 1322B and the placing portion 1322C can be integrally formed, or they can be separately processed and then assembled.

[0053] like Fig. 9 , Fig.10 As shown, as an implementation method, the seat body 1321 and the connecting portion 1322B are both disc-shaped. For example, in this embodiment, the seat body 1321 and the connecting portion 1322B are circular and can be adapted to each other, and their diameters can be equal. In addition, the circular structure will leave a gap when each adsorption component 132 is laid on the conveying mechanism 130, so that the water spraying mechanism 140 set at the lower end of the adsorption component 132 can pass the sprayed liquid through the gap to the screen glass for cooling and cleaning.

[0054] like Figure 4As shown, as an embodiment, the screen glass grinding device 100 also includes a water spraying mechanism 140 for spraying liquid to cool the heat generated during the screen glass grinding process, and a wastewater collecting mechanism 150 for collecting the liquid sprayed by the water spraying mechanism 140. The water spraying mechanism 140 is installed on the supporting bracket 110; the wastewater collecting mechanism 150 is arranged below the water spraying mechanism 140; wherein the water spraying mechanism 140 is connected with the wastewater collecting mechanism 150 so that the wastewater collecting mechanism 150 flows back into the water spraying mechanism 140. In this embodiment, since heat is generated due to friction during the grinding process, and powder particles are generated, which affects the grinding of the screen glass by the grinding mechanism 120, the water spraying mechanism 140 is arranged below the conveying mechanism 130. The water spraying mechanism 140 can spray liquid (water in this embodiment), which can cool the heat generated during the grinding process on the one hand, and can also clean the powder particles generated during the grinding process on the other hand, so as to avoid the powder particles affecting the processing and further improve the quality of the screen glass. At the same time, the waste liquid is collected by a water collecting mechanism disposed below the water spraying mechanism 140, and after being treated, the waste liquid flows back into the water spraying mechanism 140 for secondary utilization, thereby making rational use of resources and being green and environmentally friendly.

[0055] like Figure 4 As shown, as an embodiment, the wastewater collection mechanism 150 includes a collection tray 151 and a storage container 152, and the water spraying mechanism 140, the collection tray 151, and the storage container 152 are arranged in sequence along the first direction, and the water spraying mechanism 140 is connected to the storage container 152. Exemplarily, the liquid sprayed by the water spraying mechanism 140 becomes waste liquid after cooling the screen glass, and the function of the collection tray 151 is to collect these waste liquids. Then the waste liquid in the collection tray 151 flows to the storage container 152 for storage, and is transferred to the water spraying mechanism 140 for secondary use when it is needed. In this embodiment, the first direction is a vertical direction, and the nozzle of the water spraying mechanism 140 sprays upward, and the collection tray 151 is arranged below the water spraying mechanism 140 to facilitate the collection of waste water. The conveying mechanism 130 is arranged between the water spraying mechanism 140 and the grinding mechanism 120, and the conveying mechanism 130 has a hollow area so that the water spraying mechanism 140 sprays the liquid onto the grinding head of the grinding mechanism 120. In addition, it should be noted that the polishing device provided by the present application is mainly used to polish screen glass, and very few debris particles are generated. In addition, during the polishing process, most of the debris particles will adhere to the bristles of the polishing head, that is, the bristles of the polishing head have a certain filtering effect. Therefore, the waste water can be reused. Of course, the number of reuses should not be too many, and it can be replaced regularly. In addition, in this embodiment, the collection tray 151 is rectangular and the storage container 152 is cylindrical. Of course, in specific applications, the shapes of the collection tray 151 and the storage container 152 are not limited.

[0056] like Figure 1 As shown, as an embodiment, the support bracket 110 has a loading station 111, a grinding station 112 and a unloading station 113 arranged in sequence along the first direction, the grinding mechanism 120 is arranged at the grinding station 112, and the conveying mechanism 130 conveys the screen glass from the loading station 111 to the unloading station 113 through the grinding station 112. Exemplarily, in this embodiment, when the device is working, it is necessary to manually place the screen glass at the loading station 111, and then the conveying mechanism 130 conveys the screen glass to the grinding station 112, and after being polished by the grinding mechanism 120, it is conveyed to the unloading station 113 through the conveying mechanism 130, and unloading is performed manually. In addition, the second direction is the direction in which the screen glass moves in this device during processing.

[0057] like Figure 6 , Figure 7 , Figure 8 As shown, as an embodiment, the screen glass grinding device 100 further includes an air supply mechanism 170 for air-drying the water stains remaining on the screen glass after the grinding process, and the air supply mechanism 170 is installed on the supporting bracket 110. Exemplarily, in this embodiment, after the screen glass is polished, the air supply mechanism 170 is set to spray gas to air-dry the water stains remaining on the screen glass, which is conducive to further improving the processing quality of the screen glass.

[0058] like Figure 6 , Figure 7 , Figure 8 As shown, as an embodiment, the air supply mechanism 170 has an air inlet 1721, an air outlet 1722 and an air supply channel 1723, and the air inlet 1721 and the air outlet 1722 are connected through the air supply channel 1723. By way of example, in this embodiment, a fan (not shown in the figure) is connected to the air inlet 1721, and the wind generated by the fan enters from the air inlet 1721, passes through the air supply channel 1723 and is discharged from the air outlet 1722, wherein the air outlet 1722 is arranged at a position close to the screen glass, so that the water stains remaining on the screen glass can be dried by air.

[0059] like Figure 6 , Figure 7 , Figure 8As shown, as an embodiment, it is characterized in that the air supply mechanism 170 includes a fixed bracket 171 and an air supply bin 172, the air supply bin 172 is installed on the bearing bracket 110 through the fixed bracket 171, and the air inlet 1721, the air outlet 1722 and the air supply channel 1723 are all arranged on the air supply bin 172. Exemplarily, in this embodiment, the fixed bracket 171 is connected to the top of the air supply bin 172, and the air inlet 1721 is also arranged on the top of the air supply bin 172, while the air outlet 1722 is arranged at the bottom of the air supply bin 172. There are two air inlets 1721, and the screen glass is arranged below the air inlet 1721.

[0060] like Figure 5 As shown, as an embodiment, the power assembly 190 is used to provide vacuum negative pressure, and the power assembly 190 has a movable pipe joint 1931, and the pipe joint 1931 moves to connect or disconnect the pipe joint 1931 with the through groove 1321A. Exemplarily, in this embodiment, the pipe joint 1931 adopts linear movement, which is convenient for controlling the position alignment of the pipe joint 1931 and the through groove 1321A and the distance of the pipe joint 1931 to align the pipe joint 1931 with the through groove 1321A. Of course, in specific applications, the pipe joint 1931 can also adopt nonlinear movement. The screen glass grinding device 100 provided in the present application is provided with a movable pipe joint 1931 on the power assembly 190, and the pipe joint 1931 is connected or disconnected with the through groove 1321A of the adsorption assembly 132 by moving, and the control method is simple, thereby reducing the cost of the grinding equipment and increasing reliability.

[0061] like Figure 5 As shown, as an embodiment, the power assembly 190 includes a driving member 191, a guide assembly 192 and a pipe connector 193. The driving member 191 is installed on the supporting bracket 110, the guide assembly 192 is connected between the driving member 191 and the pipe connector 193, and the pipe connector 1931 is provided on the pipe connector 193. Exemplarily, in this embodiment, the driving member 191 is a telescopic cylinder, the guide assembly 192 is a slide rail slider, and the slide rail slider is used for guidance so that the position of the pipe connector 1931 can correspond to the position of the through groove 1321A, thereby improving the stability of the grinding equipment. The pipe connector 193 is arranged along the first direction, and the pipe connector 193 is a long metal tube. The pipe connectors 1931 are arranged in a row along the length direction of the pipe connector 193.

[0062] like Figure 1As shown, as an embodiment, the screen glass polishing device 100 also includes a lifting mechanism 160 for driving the polishing mechanism 120 to rise and fall. The lifting mechanism 160 is installed on the supporting bracket 110, and the lifting mechanism 160 is connected to the polishing mechanism 120. Exemplarily, the lifting mechanism 160 drives the polishing mechanism 120 to rise and fall. Since the polishing head and the screen glass are in contact when the screen glass is polished, the polishing can be performed. However, in this case, it is difficult to move the screen glass when it is polished and transferred out. Therefore, the lifting mechanism 160 is required to lift the polishing mechanism 120. That is to say, when polishing is required, the lifting mechanism 160 drives the polishing mechanism 120 to descend, and after the polishing is completed, the lowering mechanism drives the polishing mechanism 120 to rise. In this embodiment, the lifting mechanism 160 uses a cylinder, and four cylinders are set for driving, so the driving force is stronger and more stable.
