The pressing device 100 comprises a bearing member 110, a pressing device 120 and a counterweight member 130, wherein the bearing member 110 comprises a first side surface 111 and a second side surface 112 arranged oppositely, the pressing device 120 is arranged on the first side surface 111, and the pressing device 120 comprises at least one roller 121 for pressing a screen, so that the operation of pressing a display device is more smooth. Meanwhile, the counterweight member 130 is detachably arranged on the second side surface 112 to counterweight the at least one roller 121, so that the display glass is fully contacted with the back plate and is tightly adhered. When the pressing device 100 is used to press the display device, the display glass can be pressed with different forces by means of detaching and assembling the counterweight member 130 with different weights, so that the counterweight member 130 with different weights can be replaced in a simple way, and the force acting on each part of the display glass can be accurately controlled, so that the display glass is uniformly stressed when being pressed, thereby further improving the adhesion effect of the display glass and the back plate.

[0029] It should be noted that the detachable connection manner between the counterweight member 130 and the second side surface 112 is not limited in the embodiments, for example, the detachable connection manner between the counterweight member 130 and the second side surface 112 can be one of buckle connection, screw connection or magnetic attraction connection, as long as the purpose of fixing the counterweight member 130 to the second side surface 112 and detaching the counterweight member 130 from the second side surface 112 can be achieved.

[0030] Optionally, the bearing member 110 can further comprise a first side edge 113 and a second side edge 114. For example, Figure 1As shown, the first side edge 113 and the second side edge 114 are oppositely arranged on the second side surface 112 and extend away from the pressing device 120. Meanwhile, the first side edge 113 is provided with a first extension 115A at an end away from the second side surface 112, the second side edge 114 is provided with a second extension 115B at an end away from the second side surface 112, and the first extension 115A and the second extension 115B are oppositely arranged and extend towards the counterweight 130 and abut against the counterweight 130 to fix the counterweight 130 and prevent the counterweight 130 from falling off the second side surface 112 when the pressing apparatus 100 presses the display glass.

[0031] In addition, please refer to Figure 3 , Figure 3 The overall structure of the pressing apparatus provided in the embodiment is shown in the figure. In the embodiment, the first extension 115A and the second extension 115B can be arranged at two ends of the counterweight 130, and the first extension 115A and the second extension 115B can be provided with an arc edge 1151 on a side facing the counterweight 130, and meanwhile, the two ends of the counterweight 130 can be provided with an arc surface 131 corresponding to the arc edge 1151, that is, the first extension 115A and the second extension 115B can abut against the left and right ends of the counterweight 130, thereby improving the fixing effect of the first extension 115A and the second extension 115B on the counterweight 130; the arc edge 1151 cooperates with the arc surface 131, which not only further improves the fixing effect of the first extension 115A and the second extension 115B on the counterweight 130 by increasing the contact area, but also enables the counterweight 130 to be detached from the second side surface 112 along the contact surface of the arc edge 1151 and the arc surface 131, thereby improving the detaching efficiency. It can be understood that the arc edge 1151 and the arc surface 131 in the embodiment can be in interference fit, thereby further improving the fixing effect of the first extension 115A and the second extension 115B on the counterweight 130 to prevent the counterweight 130 from falling off when the pressing apparatus 100 moves.

[0032] Optionally, the carrier 110 can further include a third side edge 116 and a fourth side edge 117. Please refer to Figure 4 , Figure 4 The side surface structure of the pressing apparatus provided in the embodiment is shown in the figure. The third side edge 116 and the fourth side edge 117 are oppositely arranged on the first side surface 111 and extend away from the counterweight 130, and meanwhile, the pressing device 120 can further include a rotating shaft 122, and at least one roller 121 is rollingly connected to the rotating shaft 122, one end of the rotating shaft 122 is connected to the third side edge 116, and the other end is connected to the fourth side edge 117 to fix the roller 121. In addition, as shown in Figure 1 and Figure 2In other embodiments, the third side edge 116 and the fourth side edge 117 can also be provided with a plurality of through holes 118, and the shaft 122 can be arranged through the through holes 118 of the third side edge 116 and the fourth side edge 117, so as to better fix the roller 121. It can be understood that in embodiments, the number of the shaft 122 and the roller 121 can be multiple groups, such as 3 groups, 4 groups or 5 groups, each shaft 122 can be arranged through the through holes 118 of the third side edge 116 and the fourth side edge 117, and each roller 121 is arranged between the third side edge 116 and the fourth side edge 117 and is rolling connected to the shaft 122, and the plurality of rollers 121 are arranged along the same axial direction, so that when the pressing device 100 is used to press the display glass, the plurality of rollers 121 can press the same position of the display glass for multiple times in a stroke, thereby improving the pressing effect.

[0033] Optionally, the bearing 110 can also be provided with a mounting portion 119. For example, as shown in the figure, Figure 4 The mounting portion 119 is arranged on the side of the fourth side edge 117 away from the roller 121, and protrudes away from the roller 121 on the fourth side edge 117. Meanwhile, the pressing device 100 can also include a limiting piece 160, which is detachably connected to the mounting portion 119 along the gravity direction, and the length of the limiting piece 160 away from the fourth side edge 117 along the gravity direction is greater than the radius of the roller 121, so that in embodiments, the limiting piece 160 can be used to abut a position of the display panel, so as to limit the pressing device 100 and prevent the pressing device 100 from deviating from the original stroke when moving. In addition, the limiting piece 160 in the embodiment can also be in the form of a wheel and rolling connected to the mounting portion 119, so that when the pressing device 100 moves, the friction between the limiting piece 160 and the display panel can be reduced, so as to facilitate the movement of the pressing device 100. It can be understood that the mounting portion 119 can also be arranged on the side of the third side edge 116 away from the roller 121, and protrude away from the roller 121 on the third side edge 116, and the limiting piece 160 can also be adjusted to the side close to the third side edge 116. In addition, the detachable connection mode of the limiting piece 160 and the mounting portion 119 in the embodiment is not limited, for example, the detachable connection mode of the limiting piece 160 and the mounting portion 119 can be one of buckle connection, screw connection or magnetic attraction connection.

[0034] Optionally, the pressing device 100 can also include a handle 140. For example, as shown in the figure, Figure 3 and Figure 4The handle 140 is connected to the carrier 110 along the central axis of the counterweight 130, and the height of the handle 140 is greater than the height of the counterweight 130, the first extension 115A and the second extension 115B, that is, the handle 140 covers the counterweight 130, the first extension 115A and the second extension 115B, so that when the pressing device 100 is used to press the display glass, the operator can move the pressing device 100 by holding the top of the handle 140 to press the display glass, thereby solving the problem that the pressing device is always controlled by power in the prior art, which causes power waste. At the same time, the handle 140 is arranged at the central axis of the counterweight 130, which can better control the movement of the pressing device 120 by the handle 140, and ensure that the display glass is uniformly stressed when being pressed. It can be understood that the handle 140 in the embodiment can not only be arranged in a manner covering the first extension 115A and the second extension 115B, but also can be arranged in a manner that one end is connected to the third side 116 and the other end is connected to the fourth side 117, and arranged along the central axis of the counterweight 130.

[0035] In addition, please refer to Figure 4 and refer to Figure 5 , Figure 5 The working schematic diagram of the pressing device provided by the embodiment of the present application when pressing the display equipment. When the pressing device 100 needs to be operated to press the display glass, the limiting piece 160 can be abutted to one side of the display equipment 200, and the counterweight 130 with accurate weight is placed on the second side 112, and then the pressing device 100 is moved by holding the handle 140, so that the pressing device 100 can move around the periphery of the display equipment 200 to accurately press the four sides of the display equipment 200. When the four sides of the display equipment 200 are pressed, the limiting piece 160 can be dismounted from the mounting portion 119, at this time, the counterweight 130 with the original weight value can be replaced by a counterweight 130 with other weight value and installed on the second side 112, and the pressing device 100 is moved again by holding the handle 140 to press the middle area of the display equipment 200, so as to ensure that the display glass of the display equipment 200 is uniformly stressed when being pressed, and avoid the situation that some areas of the display glass are excessively stressed, which causes damage to the display glass, or some areas of the display glass are insufficiently stressed, which causes poor adhesion between the display glass and the back plate.

[0036] Optionally, the second side 112 can also be provided with a groove 1121. Please refer to Figure 6 , Figure 6The schematic diagram of the overall structure of the screen pressing device after hiding the counterweight is provided for another embodiment of the present application. The groove 1121 comprises a bottom surface 1122 and a side surface 1123 arranged around the bottom surface 1122, the side surface 1123 is provided with a sliding groove (not shown in the figure), and a plurality of sliding members 1124 are arranged in the sliding groove. Meanwhile, the first side edge 113 and the second side edge 114 are arranged in the groove 1121 and have a certain gap with the bottom surface 1122, and one end of the first side edge 113 close to the bottom surface 1122 and one end of the second side edge 114 close to the bottom surface 1122 are connected with the plurality of sliding members 1124, so that the first side edge 113 and the second side edge 114 are slidably connected to the second side surface 112. In addition, the screen pressing device 100 can further comprise at least two springs 150, one end of one of the at least two springs 150 is connected to one side of the handle 140, and the other end is connected to the first side edge 113; one end of the other of the at least two springs 150 is connected to the other side of the handle 140, and the other end is connected to the second side edge 114. Since the volume of the counterweight 130 will change accordingly after replacing the counterweight 130 with different weight values (under the same density, the counterweight 130 with a larger weight value has a larger volume, and the counterweight 130 with a smaller weight value has a smaller volume), the spring 150 is used in cooperation with the sliding member 1124 to fix the counterweight with different volumes. When the volume of the counterweight is large, the first side edge 113 and the second side edge 114 are driven by the sliding member 1124 to move towards both sides, at this time, since the spring 150 is compressed, the spring 150 will also exert a force towards the first side edge 113 and the second side edge 114, so that the counterweight with a larger volume can be better fixed; when the volume of the counterweight is small, the first side edge 113 and the second side edge 114 can be driven by the sliding member 1124 to move towards the middle of the groove 1121, until abutting against the counterweight with a smaller volume and fixing the counterweight 130, at this time, the spring 150 will restore and will not exert a force on the first side edge 113 and the second side edge 114.

[0037] It should be noted that the specific shape of the sliding member 1124 is not limited in the embodiment, for example, the sliding member 1124 can be in the shape of a wheel, a square, etc.; and the friction coefficient between the sliding member 1124 and the sliding groove can be increased to achieve a better fixing effect of the counterweight 130.
