[0033] In order to illustrate the technical solutions described in the present application, the following will be described in detail in combination with specific drawings and embodiments.

[0034] In combination with Figs. 1-3 As shown in one or more embodiments, the present application provides a flexible circuit board (FPC: Flexible Printed Circuit) pressure maintaining jig, which comprises: a positioning platform 100 and a first moving device 101; the positioning platform 100 is used to support a display screen and a flexible circuit board; the first moving device 101 comprises a first linear driving mechanism 102 and a pressure head 103, the first linear driving mechanism 102 is used to make the pressure head 103 move linearly, and the pressure head 103 can approach or move away from the display screen; wherein the pressure head 103 can be in contact with the flexible circuit board, so that the flexible circuit board is clamped between the pressure head 103 and the display screen. The flexible circuit board pressure maintaining jig provided by the present application makes the positioning platform 100 bear the display screen with the flexible circuit board attached, then places the display screen on the positioning platform 100, then makes the first linear driving mechanism 102 drive the pressure head 103 to move, so that the pressure head 103 is in contact with the flexible circuit board, so that the flexible circuit board is clamped between the pressure head 103 and the display screen, then waits for a set time, and then moves the pressure head 103 away from the display screen. In this way, the pressure head 103 can uniformly press the flexible circuit board, and can be compacted, thereby reducing the occurrence of the edge lifting phenomenon of the flexible circuit board, reducing the local area leakage of the flexible circuit board, thereby ensuring the overall appearance of the product and the function of the product. In addition, the pressure head 103 can also maintain uniform force during pressing, thereby avoiding the occurrence of wrinkles in the flexible circuit board, thereby being conducive to ensuring product quality and improving production efficiency.

[0035] In some embodiments, the positioning platform 100 is used to support and position the display screen. After the release film on the flexible circuit board is removed, the flexible circuit board is attached to the display screen at a designated position, the double-sided adhesive on the flexible circuit board is adhered to the designated position of the display screen, and then the positioning platform 100 is used to position the position of the display screen. Thus, after the pressing head 103 moves towards the display screen, the pressing head 103 can contact the flexible circuit board to press the flexible circuit board, so that the double-sided adhesive on the flexible circuit board fully contacts the display screen, and the flexible circuit board and the display screen are firmly adhered. For example, the linear motion of the pressing head 103 can be linear motion in the vertical direction, so that the pressing head 103 can move up and down under the driving of the first linear driving mechanism 102. The display screen can be a touch display screen, and the touch display screen includes a touch screen. The material of the touch screen can be ITO glass.

[0036] In combination Figs. 1-3 As shown in the drawings, in some embodiments, the positioning platform 100 includes a support panel 104 and a plurality of positioning blocks 105. The positioning blocks 105 are installed on the support panel 104. Thus, the support panel 104 can be used to support the display screen, and the positioning blocks 105 can be used to position the position of the display screen on the support panel 104. For example, the plurality of positioning blocks 105 can be used to position two adjacent side edges of the display screen. In use, a part of the plurality of positioning blocks 105 are located at one side edge of the display screen and contact the side edge, and the remaining part of the plurality of positioning blocks 105 are located at the adjacent side edge of the display screen and contact the side edge. Thus, the position of the display screen on the support panel 104 is positioned, so that the pressing head 103 below can be aligned with the flexible circuit board. The panel surface of the support panel 104 can be flat, so as to support the display screen.

[0037] In combination Figs. 1-3 As shown in the drawings, in some embodiments, a plurality of positioning holes 106 can be arranged on the support panel 104 in rows and columns. One side of the positioning block 105 facing the support panel 104 can be fixed with a positioning pin. The positioning pin and the positioning hole 106 can be in interference fit. The positioning pin is inserted into the positioning hole 106 to fix the position of the positioning block 105 on the support panel 104. Because a plurality of positioning holes 106 are provided, the position of the positioning block 105 can be changed as needed. It can be understood that although the positioning pin and the positioning hole 106 are in interference fit, the positioning pin can still be forcibly pulled out to change the position of the positioning block 105.

[0038] In combination Figs. 1-3As shown, in some embodiments, the pressing head 103 comprises a flat plate 107 and a buffer layer 108, the buffer layer 108 is fixed on the flat plate 107; the flat plate 107 is connected with the first linear driving mechanism 102, the flat plate 107 is used to facilitate the connection with the first linear driving mechanism 102, and also facilitates the installation of the buffer layer 108 and the flat plate 107. For example, the plate surface of the flat plate 107 connected with the buffer layer 108 can be flat, and the buffer layer 108 and the flat plate 107 can be fixedly connected by bonding. The area of the surface of the buffer layer 108 in contact with the flexible circuit board is greater than the area of the flexible circuit board, so that sufficient pressure can be applied to the flexible circuit board.

[0039] In some embodiments, the material of the flat plate 107 is bakelite, and the material of the buffer layer 108 is foamed silica gel. The use of bakelite facilitates processing, and the use of foamed silica gel as the material of the buffer layer 108 can achieve buffering, which is beneficial to protect the display screen when the flexible circuit board is pressed.

[0040] In some embodiments, the first linear driving mechanism 102 is a pneumatic cylinder, an electric cylinder or a hydraulic cylinder. For example, the first linear driving mechanism 102 is a pneumatic cylinder, so that the linear motion of the pressing head 103 can be achieved by the extension and retraction of the pneumatic cylinder; the flat plate 107 of the pressing head 103 is fixedly connected with the end of the extension rod of the pneumatic cylinder.

The dotter 111 comprises a marker pen 113 and a fixing frame 114 mounted on the second linear driving mechanism, and the fixing frame 114 has a fixing hole, and the marker pen 113 is inserted and fixed in the fixing hole, for example, the marker pen 113 can be fixed by adhesion or clamping. In use, the second linear driving mechanism 112 can drive the dotter 111 to move up and down to realize the dotting operation of the marker pen 113 on the dotter 111 on the display screen. It should be noted that the dotter 111 is a mechanism with the marker pen 113, which realizes dotting by using the marker pen 113 to dot on the display screen; since the structure of the dotter 111 itself is not improved in the present application, the structure of the dotter 111 will not be described in detail.

[0043] In combination Figs. 1-3 As shown, in some embodiments, the first moving device 101 further comprises a first starting switch 115 for controlling the extension and retraction of the first linear driving mechanism 102, so that the first starting switch 115 can be used to control the first linear driving mechanism 102 to drive the pressure head 103 to approach or move away from the display screen, so as to realize the contact or separation of the pressure head 103 and the flexible circuit board on the display screen. It should be noted that, in order to ensure that the pressure head 103 will not damage the display screen, when manufacturing the flexible circuit board pressure maintaining jig, after the extension rod of the first linear driving mechanism 102 is extended to a certain length, the pressure head 103 will not damage the display screen after contacting the flexible circuit board, for example, the installation height of the first linear driving mechanism 102 on the bracket 109 can be adjusted, so that the movement distance of the pressure head 103 is a preset value, so as to ensure the pressure of the pressure head 103 on the flexible circuit board, i.e. to meet the pressure maintaining requirement and not to damage the display screen.

[0044] In some embodiments, the second linear driving mechanism 112 is a gas cylinder, an electric cylinder or a hydraulic cylinder; so that the linear motion of the dotter 111 can be realized by the extension and retraction of the gas cylinder; the fixing frame 114 of the dotter 111 is fixedly connected with the end of the extension rod of the gas cylinder. It can be understood that in some other possible implementations, the second linear driving mechanism 112 can also adopt other linear motion mechanisms, for example, an electric linear slide rail.

[0045] In combinationFigs. 1-3 As shown, in some embodiments, the second moving device 110 further comprises a second starting switch 116 for controlling the extension and retraction of the second linear driving mechanism 112; in this way, the second starting switch 116 can be used to control the second linear driving mechanism 112 to drive the marker pen 113 on the marker 111 to approach or move away from the display screen, so as to realize the contact or separation of the marker pen 113 on the marker 111 and the display screen. It should be noted that, in order to ensure that the marker 111 will not damage the display screen, when manufacturing the flexible circuit board pressure maintaining fixture, debugging is needed; after the extension rod of the second linear driving mechanism 112 extends to a certain length, the marker 111 will not damage the display screen after contacting the display screen. For example, the installation height of the second linear driving mechanism 112 on the support 109 can be adjusted, so that the movement distance of the marker 111 is a preset value, so as to realize the marking of the display screen by the marker 111 without damaging the display screen.
