As Figures 1 - 3 shown, this embodiment provides a pressing device, which includes a pressing assembly 100. The pressing assembly 100 includes a support frame 110 and a flexible pressing surface 120. The support frame 110 is set in a U shape and can be placed on the edge of the panel to be pressed; the flexible pressing surface 120 is arranged inside the support frame 110, and a pressing cavity is surrounded between the flexible pressing surface 120 and the inner wall of the support frame 110. The volume of the pressing cavity is adjustable to drive the flexible pressing surface 120 to deform. When the flexible pressing surface 120 deforms towards the inside of the support frame 110, it can flexibly press against the front and / or back of the panel to be pressed 1.

[0037] By providing the pressing assembly 100, it is used to press the mylar attached to the panel. A flexible pressing surface 120 is arranged inside the support frame 110 of the pressing assembly 100, and a pressing cavity is formed between the flexible pressing surface 120 and the inside of the support frame 110. According to the change of the volume of the pressing cavity, the flexible pressing surface 120 can deform. When the volume of the pressing cavity becomes larger, the flexible pressing surface 120 deforms towards the inside of the support frame 110. At this time, the flexible pressing surface 120 can flexibly press against the front and back of the panel to be pressed 1 to press the mylar on the front and back of the panel to be pressed 1, ensuring the reliable adhesion between the mylar and the panel to be pressed 1. The contact between the flexible pressing surface 120 and the panel to be pressed 1 is surface contact, which can effectively reduce the fragment caused by uneven stress on the panel to be pressed 1; at the same time, the surface contact is also beneficial to increasing the contact area with the panel to be pressed 1 and ensuring the pressing effect; in addition, the flexible pressing surface 120 is flexibly arranged, and it is no longer a hard force contact with the panel to be pressed 1, further reducing fragments; and it can also reduce or avoid damage to the electronic components on the panel to be pressed 1. By pressing the panel to be pressed 1 with the pressing device, the labor cost is effectively reduced, the pressing quality is improved, and at the same time, the yield rate is effectively reduced.

[0038] Specifically, an air inlet and an air outlet communicating with the pressing cavity are arranged on the support frame 110. The air inlet is used to introduce air into the pressing cavity, and the air outlet is used to discharge the gas in the pressing cavity. By changing the amount of gas in the pressing cavity to change the volume of the pressing cavity, the damage of the flexible pressing surface 120 to the panel to be pressed 1 and the electronic components thereon can be further reduced, thereby reducing the occurrence of fragment situations.

[0039] Figure 4 It is a schematic diagram of the vacuum generator of the pressing device provided by the specific embodiment of the present utility model. As Figure 4 shown, in this embodiment, the pressing device further includes a vacuum generator 300. By setting the vacuum generator 300, it is used to supply air or exhaust air into the pressing cavity to change the volume of the pressing cavity. The vacuum generator 300 is provided with an air supply port 320 and a vacuum port 330. Among them, the vacuum port 330 is used to extract air to create negative pressure and supply air to create positive pressure. A vacuum valve 331 is provided on the vacuum port 330; the air supply port 320 is used to supply air to the vacuum port 330, and an air supply valve 321 is provided on the air supply port 320. Both the vacuum valve 331 and the air supply valve 321 are communicatively connected to the control board 340, and the control board 340 is used to control the on / off and opening degree of the vacuum valve 331 and the air supply valve 321. Preferably, the vacuum generator 300 is further provided with a silencer 310 to reduce the noise during air supply and exhaust.

[0040] Furthermore, the pressing device further includes an intake pipe 111 and an exhaust pipe 112. The intake pipe 111 is communicated with the intake port, and the exhaust pipe 112 is communicated with the exhaust port. It can be understood that one end of the intake pipe 111 away from the intake port is communicated with the air supply port 320 of the vacuum generator 300, and one end of the exhaust pipe 112 away from the exhaust port is communicated with the vacuum port 330 of the vacuum generator 300. Optionally, both the intake port and the exhaust port are arranged on the bottom edge of the U-shaped support frame 110, which is convenient for installing the intake pipe 111 and the exhaust pipe 112.

[0041] Exemplarily, four pressing components 100 are provided, corresponding to the four sides of the panel 1 to be pressed respectively, which is beneficial to improving the pressing efficiency of the panel 1 to be pressed. And the support frame 110 is adapted to the side length of the panel 1 to be pressed, so that the four sides of the panel 1 to be pressed can be pressed by the flexible pressing surface 120, ensuring the reliability of the pressing.

[0042] Preferably, a pressure detection component is provided on the flexible pressing surface 120 for detecting the pressure between the flexible pressing surface 120 and the panel 1 to be pressed; and / or, a pressure detection component is provided in the pressing cavity for detecting the pressure of the gas in the pressing cavity. It can be understood that the pressure between the flexible pressing surface 120 and the panel 1 to be pressed and the pressure of the gas in the pressing cavity can both be used to monitor the pressing force of the pressing component 100 on the panel 1 to be pressed, so as to ensure the pressing effect without damaging the panel 1 to be pressed and the electronic components thereon.

[0043] Specifically, when the flexible pressing surface 120 deforms towards the inner side of the support frame 110, it presses against at least one side of the panel 1 to be pressed for a preset distance h. The length of the side perpendicular to this side is d, and the ratio of h to d is set to 1 / 5 - 1 / 4. This setting ensures that there is a certain contact area between the pressing assembly 100 and the panel 1 to be pressed, thereby ensuring the pressing effect.

[0044] Furthermore, the pressing device further includes a handling assembly. The pressing assembly 100 is arranged at the handling end of the handling assembly. By setting the handling assembly, it is used to drive the pressing assembly 100 to approach or move away from the panel 1 to be pressed, improving the automation degree of the pressing device. Optionally, the handling assembly and the pressing assembly 100 are arranged in one-to-one correspondence, and the handling assembly can be set as a robotic arm.

[0045] In this embodiment, the pressing device further includes a support assembly 200. The support assembly 200 is used to support the panel 1 to be pressed. It can be understood that the support assembly 200 supports the panel 1 to be pressed to suspend the edge of the panel 1 to be pressed, so as to avoid interference with the pressing of the panel 1 to be pressed by the pressing assembly 100.

[0046] Specifically, the support assembly 200 includes a support table 210, and an adsorption head 220 is arranged on the support table 210. The adsorption head 220 can be used to adsorb the panel 1 to be pressed. By adsorbing the panel 1 to be pressed with the adsorption head 220, while realizing the fixation of the panel 1 to be pressed, it will not cause damage to the panel 1 to be pressed.

[0047] The use process of the above pressing device is as follows: First, place the panel 1 to be pressed on the support assembly 200, adsorb and fix it through the adsorption head 220, and suspend the edge of the panel 1 to be pressed; then the handling assembly transports the pressing assembly 100 to cover the edge of the panel 1 to be pressed; next, the vacuum generator 300 injects air into the pressing cavity to make the flexible pressing surface 120 press the edge of the panel 1 to be pressed and last for a preset time; finally, the vacuum generator 300 discharges the air in the pressing cavity, and the handling assembly transports the pressing assembly 100 away from the panel 1 to be pressed.
