DETAILED DESCRIPTION
[0043] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.
[0044] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should be understood by people with ordinary skills in the field to which the present application belongs. The "first", "second" and similar words used in the present application do not represent any order, quantity or importance, but are only used to distinguish different components. "Including" or "comprising" and similar words mean that the elements or objects listed in front of the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connecting" or "connected" and similar words are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.
[0045] See also Figure 1 and Figure 2 As shown, currently conventional large-size capacitive screens mostly fix tempered glass 02, capacitive film 04 and liquid crystal display panel 06 to form an integrated display screen, and then install a front shell 05 around the display screen, and then install a back plate on the back of the display screen to finally form a capacitive screen product.
[0046] The width of the black border of a capacitive screen is an important factor affecting its practicality and aesthetics. The industry has been studying how to reduce the width of the black border of a capacitive screen as much as possible.
[0047] See also Figure 2 As shown, the whole black border H of the capacitive screen includes the capacitor black border M, the extra black border P of the tempered glass (that is, the part where the tempered glass 02 is more than the capacitor film 04) and the black border caused by installing the front shell 05. Among these three parts, since the high-end capacitive screen requires higher recognition accuracy and more stable recognition accuracy, this requires sufficient capacitor black border M to arrange the channel routing, so the capacitor black border M cannot be reduced, otherwise it will reduce the recognition accuracy and accuracy of the product. At present, the black border caused by installing the front shell 05 has basically reached the process limit and it is difficult to continue to reduce it. Therefore, at present, the only way to reduce the whole black border H of the capacitive screen is to reduce the width of the extra black border P of the tempered glass.
[0048] However, the existing installation method of the front shell 05 and the display screen is to fix them with glue 03, and the glue 03 is used to fix the tempered glass 02 of the display screen to the front shell 05, and the adhesive area N of the glue 03 must be on the tempered glass 02 outside the capacitor film 04. Once the glue 03 sticks to the capacitor film 04, the capacitor film 04 will be damaged. Figure 2 In order to prevent the glue 03 from sticking to the capacitor film 04, the size of the tempered glass 02 must be made very large, so that the tempered glass 02 has a larger adhesive area N and a reserved area than the size of the capacitor film 04 to prevent the glue 03 from flowing near the capacitor film 04, which results in a wider extra black border P of the tempered glass of the capacitor screen. In addition, when the glue 03 is bonded, the glue 03 changes from liquid to solid, and the stress is concentrated. Moreover, the solid glue makes it impossible to eliminate the stress. Once there is a strong mechanical disturbance, it is easy to cause the glue 03 to fail and crack, and the adhesive substrate is also easily damaged.
[0049] Based on this, see Figure 3 and Figure 4 The present application provides a display device, comprising: a display screen 1 and a frame 3. The display screen 1 comprises a cover plate 11, a capacitive touch film 12 and a display panel 13 stacked in sequence. The frame 3 is arranged around the display screen 1, and the frame 3 is bonded to a side of the capacitive touch film 12 away from the cover plate 11 through a first adhesive member 2.
[0050] Specifically, the capacitive touch film 12 includes a display area (ie Figure 4The AA area in the capacitive touch film 12 and the non-display area are the capacitive black border M. The frame 3 is bonded to the non-display area of the capacitive touch film 12 by the first adhesive 2, so that the display screen 1 and the frame 3 can be fixed, and the capacitive black border M can be used to fix the frame 3. There is no need to provide extra space to fix the frame 3, and there is no need to use the cover plate 11 to connect with the frame 3. Therefore, the cover plate 11 only needs to cover the capacitive touch film 12, and there is no need to extend the capacitive touch film 12 too much. The width of the cover plate 11 extending beyond the capacitive touch film 12 can be reduced, so that the black border of the product can be reduced to achieve a narrow frame, and the capacitive black border M will not be reduced. The black width of the product can be reduced while ensuring the accuracy and precision of product recognition, thereby improving the practicality and aesthetics of the product.
[0051] The first adhesive member 2 may be a double-sided adhesive tape, such as Very High Bond (VHB) acrylic tape, 3M double-sided adhesive tape, etc. Since the first adhesive member 2 has a certain buffering effect, it can provide better buffering and shock resistance, and can better protect the display screen 1.
[0052] The cover plate 11 may be tempered glass, and the display panel 13 may be a liquid crystal display panel. It is worth noting that the display panel 13 may be a liquid crystal display panel of any existing structure, and its specific structure is not limited here.
[0053] The frame 3 is arranged around the display screen 1 to fix and protect the display screen 1. For example, the frame 3 can be arranged only around a portion of the display screen 1, or can be arranged around the entire display screen 1. The specific setting position of the frame 3 is set according to actual needs and is not limited here.
[0054] In some embodiments, a boss 35 is provided on the side of the frame 3 away from the display screen 1, and the top of the boss 35 is higher than the top of the display screen 1, so that the frame 3 can protect the display screen 1 and prevent the display screen 1 from being accidentally worn or damaged. At the same time, the setting of the boss 35 can also limit the movement of the display screen 1 and prevent the display screen 1 from moving under the action of external force. There is a gap between the boss 35 and the display screen 1, which not only facilitates the installation between the frame 3 and the display screen 1, but also prevents the boss 35 from being too close to the display screen 1 during the installation process, thereby causing damage to the display screen 1.
[0055] The capacitive touch film 12 is usually connected to a flexible circuit board 6, which is used to electrically connect the circuit on the capacitive touch film 12 with an external circuit, for example, to electrically connect the circuit on the display screen 1 of the mobile phone with the circuit board inside the mobile phone. The flexible circuit board 6 is preferably bonded or bound to the capacitive touch film 12 by hot pressing. One end of the flexible circuit board 6 is connected to the capacitive touch film 12, and the other end extends outward to connect to the capacitive control board 9.
[0056] Since the existing capacitive screen uses glue 03 to fix the front shell 05 and the display screen 1, in order to prevent the flow of glue 03 from affecting the installation of the flexible circuit board of the capacitive film 04, a safe distance must be reserved between the installation position of the flexible circuit board and the adhesive area N, which further increases the width of the extra black border P of the tempered glass, so that the width of the black border H of the existing capacitive screen is relatively wide, and a narrow border cannot be achieved.
[0057] Based on this, in some embodiments, see Figure 5 The display device of the present application further includes a flexible circuit board 6. One end of the flexible circuit board 6 is connected to the lead-out area of the capacitive touch film 12, and the other end of the flexible circuit board 6 is used to connect to the capacitive control board 9.
[0058] Specifically, since the present application uses the first adhesive 2 to bond the capacitive touch film 12 to the frame 3, the first adhesive 2 has no fluidity and will not affect the installation of the flexible circuit board 6, so that the flexible circuit board 6 can be directly connected to the line output area of the capacitive touch film 12 without considering the position of the first adhesive 2 and without reserving a safe area, thereby reducing the space required for installing the flexible circuit board 6 (the space required in the direction of the black border width), and can further reduce the excess width of the cover plate out of the capacitive touch film 12 to further reduce the black border of the product.
[0059] One end of the flexible circuit board 6 is connected to the output area of the capacitive touch film 12, and the other end of the flexible circuit board 6 is used to connect to the capacitor control board 9, so that the flexible circuit board 6 can connect the circuit on the capacitive touch film 12 to the capacitor control board 9, and then the flexible circuit board 6 can transmit the data signal generated by the capacitive touch film 12 to the capacitor control board 9.
[0060] The capacitor control board 9 is connected to the main control board (such as a control chip) of the display device, so that the capacitor control board 9 can transmit the data signal generated by the capacitive touch film 12 to the main control board, and can also transmit the control signal issued by the main control board to the capacitive touch film 12, thereby realizing data transmission between the capacitive touch film 12 and the main control board.
[0061] When installing the existing flexible circuit board 6, after connecting one end of the flexible circuit board 6 to the capacitive touch film 12, the other end of the flexible circuit board 6 needs to pass through the frame 3, bracket and other metal structures below the display screen 1 before connecting to the capacitor control board 9. This connection method, on the one hand, increases the installation space of the flexible circuit board 6, thereby increasing the black edge of the product; on the other hand, the flexible circuit board 6 passes through various metal structures, and the metal structures may cause wear on the wires of the flexible circuit board 6, causing the flexible circuit board 6 to fail to work normally. In addition, this connection method makes the assembly efficiency extremely low, and inspection and maintenance are also relatively difficult. At the same time, the installation of the existing flexible circuit board 6 requires the cover plate 11 as a support, so the cover plate 11 needs to have extra space to support the flexible circuit board 6, resulting in the size of the cover plate 11 being large, which in turn causes the width of the black edge of the product to be wider.
[0062] Based on this, see Figure 6 and Figure 7 In some embodiments, the flexible circuit board 6 includes a bending area 63, and the bending area 63 forms a protrusion 61 on the side of the capacitive touch film 12 away from the cover plate 11. The frame 3 is provided with a first groove 31 at a position corresponding to the protrusion 61, and the protrusion 61 is at least partially located in the first groove 31.
[0063] Specifically, in the present application, the flexible circuit board 6 includes a bending area 63, one end of the flexible circuit board 6 is fixed to the capacitive touch film 12, and the other end of the flexible circuit board 6 is bent at the edge of the capacitive touch film 12 and then extends out in turn along the edge direction of the capacitive touch film 12 and the display panel 13 and connected to the capacitive control board 9, so that the flexible circuit board 6 does not need to pass through any metal structure, and will not cause damage to the flexible circuit board 6 by the metal structure. At the same time, the bending of the flexible circuit board 6 can reduce the space required for installing the flexible circuit board 6, further reducing the black edge of the product.
[0064] At the same time, after the edge of the capacitive touch film 12 is bent, the other end of the flexible circuit board 6 extends out along the edge direction of the capacitive touch film 12 and the display panel 13 in sequence, so that the installation and bending of the flexible circuit board 6 do not require the cover plate 11 as a support, so there is no need for the cover plate 11 to be too much farther away from the capacitive touch film 12, so that the size of the cover plate 11 can be further reduced to further reduce the black edge of the product.
[0065] Since the wires of the flexible circuit board 6 cannot be directly folded in half, and folding in half may cause damage to the wires of the flexible circuit board 6, the bending of the flexible circuit board 6 will cause the bending area 63 to form a protrusion 61 on the side of the capacitive touch film 12 away from the cover plate 11. In this way, in order to cooperate with the installation of the protrusion 61, in the present application, the frame 3 is provided with a first groove 31 at a position corresponding to the protrusion 61, so that the protrusion 61 is at least partially located in the first groove 31, which is convenient for installation, and can further save the installation space of the flexible circuit board 6, and further reduce the black edge of the product.
[0066] In some embodiments, see Figure 7 The bending area 63 includes a first portion 631 and a second portion 632 that are arranged opposite to each other. The first portion 631 is connected to the capacitive touch film 12 , and the second portion 632 is spaced apart from the capacitive touch film 12 .
[0067] Continue to see Figure 8 and Fig. 9 In order to further reduce the installation space of the flexible circuit board 6, in the present application, the display device further includes a second adhesive member 7, the second adhesive member 7 bonds part of the first portion 631 and part of the second portion 632, and the unbonded portion of the first portion 631 and the second portion 632 forms the protrusion 61. For example, see Fig. 9 As shown, the unbonded parts of the first portion 631 and the second portion 632 form two small raised sub-portions 611 , and the two raised sub-portions 611 constitute the raised portion 61 .
[0068] Specifically, by providing the second adhesive 7, the second adhesive 7 can bond part of the first portion 631 and part of the second portion 632 to reduce the space occupied by the raised portion 61. At the same time, since the flexible circuit board 6 cannot be directly folded, even if the second adhesive 7 is provided, the unbonded portion of the first portion 631 and the second portion 632 will form two small raised sub-portions 611, which can ensure that the flexible circuit board 6 will not be excessively bent and fail.
[0069] In some embodiments, see Figure 5 and Figure 6 The capacitive touch film 12 includes an outlet side 121, the frame 3 includes an outlet side frame 33, and the outlet side frame 33 is arranged opposite to the outlet side 121; the outlet side 121 includes the outlet area, and the outlet side frame 33 is provided with a first groove 31, and the first groove 31 is arranged corresponding to the outlet area.
[0070] Specifically, the outgoing line side of the capacitive touch film 12 can be any side, which is not limited here.
[0071] The outlet side frame 33 is provided with a first groove 31 at a position corresponding to the outlet area, so that the protrusion 61 can be located exactly in the first groove 31, which is convenient for installation, and can further save the installation space of the flexible circuit board 6 and further reduce the black edge of the product.
[0072] After the protrusion 61 is placed in the first groove 31, in order to continue to provide good support and protection for the flexible circuit board 6, in some embodiments, Figure 6 and Figure 7 The outlet side frame 33 includes a side frame body 331 and a first bracket 332. The first bracket 332 is arranged on a side of the side frame body 331 close to the display screen 1. In a first direction, the first groove 31 is formed between the side frame body 331 and the first bracket 332. The first direction is a direction parallel to the display screen 1 (such as Figure 6 ZS direction shown).
[0073] A protective layer 4 is disposed on the first bracket 332 near the flexible circuit board 6 . The flexible circuit board 6 further includes a flat region 62 . The protective layer 4 is connected to the flat region 62 .
[0074] Specifically, the protective layer 4 is provided at the position of the first bracket 332 close to the flexible circuit board 6, that is, the protective layer 4 is provided at the position of the first bracket 332 close to the capacitive touch film 12 and the position of the first bracket 332 close to the protrusion 61, so that the protective layer 4 can protect the flexible circuit board 6 without causing damage to the flexible circuit board 6.
[0075] Furthermore, the protection layer 4 is connected to the flat area 62 to achieve better support for the flexible circuit board 6. The flat area 62 of the flexible circuit board 6 can be bonded to the side of the capacitive touch film 12 away from the cover plate 11 to achieve better fixation.
[0076] See also Fig.10 In some embodiments, the wire-outlet side also includes a non-wire-outlet area, and the wire-outlet side frame 33 also includes a second bracket 333 , the second bracket 333 is bonded to the non-wire-outlet area through the first adhesive 2 , and the second bracket 333 is connected to the side frame body 331 .
[0077] Specifically, the second bracket 333 is bonded to the non-line-outgoing area of the capacitive touch film 12 through the first adhesive 2, so that the position corresponding to the line-outgoing side frame 33 and the non-line-outgoing area can still be connected to the second adhesive 7 through the second bracket 333, thereby realizing the bonding of the frame 3 and the capacitive touch film 12.
[0078] The second bracket 4 is connected to the side frame body 331. For example, the second bracket 4 can be connected to the side frame body 331 by bonding, snapping, fixed connection, etc., and the specific connection method is not limited.
[0079] Exemplarily, a mounting groove 3311 is provided at a position of the side frame body 331 corresponding to the non-wire-outlet area, and the second bracket 333 includes a mounting portion 3331, and the mounting portion 3331 is snap-fitted and fixed to the mounting groove 3311, thereby achieving fixation between the frame 3, the second bracket 333 and the display screen 1.
[0080] Specifically, a portion of the mounting portion 3331 extends into the mounting groove 3311, a portion of the mounting portion 3331 that does not extend into the mounting groove 3311 is provided with a snap-in groove, and a side wall of the mounting groove 3311 extends into the snap-in groove, thereby achieving snap-in connection between the mounting portion 3331 and the mounting groove 3311.
[0081] After the mounting portion 3331 and the mounting groove 3311 are engaged, they can be fixed by bonding, bolting, screwing, etc. In this embodiment, after the mounting portion 3331 and the mounting groove 3311 are engaged, the mounting portion 3331 and the mounting groove 3311 are fixedly connected by screws to ensure the stability of the connection between the frame body 331 and the second bracket 333.
[0082] Optionally, the mounting groove 3311 can be manufactured into the same structure as the first groove 31 using the same process, so that the side frame body 331 has the same structure in the wire outlet area and the non-appearance area, and thus there is no need to distinguish between the wire outlet area and the non-wire outlet area during installation, and the protrusion 61 can be placed in the first groove 31 at the corresponding position without deliberate alignment. At the same time, the mounting groove 3311 can also be snap-connected with the second bracket 333 to achieve fixation between the frame 3, the second bracket 333 and the display screen 1, which is convenient for actual production and installation and reduces the complexity of the installation process.
[0083] In some embodiments, the first bracket 332 and the second bracket 333 are formed as an integrated structure, which ensures the stability of the connection between the first bracket 332, the second bracket 333 and the frame body 331 on the one hand, and facilitates the actual assembly process on the other hand, so that the first bracket 332 and the second bracket 333 can be installed to a specific position more quickly during actual assembly.
[0084] In some embodiments, see Fig.10The second bracket 333 is provided with a second groove 5, one side of the first adhesive member 2 is bonded to the bottom wall of the second groove 5, and the other side is bonded to the capacitive touch film 12. The second groove 5 can limit the first adhesive member 2, facilitate the installation of the first adhesive member 2, and prevent the first adhesive member 2 from being displaced under the action of external forces.
[0085] In some embodiments, see Figure 4 and Figure 5 The capacitive touch film 12 further includes a non-outlet side 122, and a third groove 32 is provided on the non-outlet side frame 34 of the frame 3 corresponding to the non-outlet side 122. One side of the first adhesive member 2 is bonded to the bottom wall of the third groove 32, and the other side is bonded to the capacitive touch film 12. The third groove 32 can limit the first adhesive member 2, facilitate the installation of the first adhesive member 2, and prevent the first adhesive member 2 from being displaced under the action of external forces.
[0086] Specifically, the display device provided in the present application may be a product with an image display function, such as: a display, a television, a billboard, a digital photo frame, a laser printer with a display function, a telephone, a mobile phone, a personal digital assistant (PDA), a digital camera, a portable camcorder, a viewfinder, a navigator, a vehicle, a large-area wall, a home appliance, an information query device (such as business query equipment and monitors of e-government, banks, hospitals, power and other departments).
[0087] In the actual manufacture of the display device of the present application, bending the flexible circuit board 6 is an essential step. In the actual manufacture, the free end of the flexible circuit board 6 that is not connected to the capacitive touch film 12 needs to be bent from Fig.11 Bend to the position shown Fig.12 The position shown in the figure is then connected to the free end of the bent flexible circuit board 6 and the capacitor control board 9. The capacitor control board 9 is usually arranged on the backlight side (ie, the non-light emitting side) of the backlight module of the display screen 1.
[0088] At present, the bending of the flexible circuit board 6 is all done manually, which has the following two problems: (1) During the manual bending process, the bending force of each cable in the flexible circuit board 6 is different, resulting in different lengths and offset angles of the cables after bending. If the cables are too short or offset after bending, the cables will be stressed when connected to the capacitor control board 9 or even unable to connect to the capacitor control board 9. If the cables are too long, they will bulge. (2) It takes about 35 seconds to complete the manual bending of each cable, which is a long time and has low production efficiency.
[0089] Based on this, see Fig.13 and Fig.14The present application also provides a mounting fixture for the display device, including a flexible circuit board mounting fixture 8, wherein the flexible circuit board mounting fixture 8 includes a base 81, wherein the base 81 is provided with a mounting opening 82, wherein a roller 83 is rollingly arranged in the mounting opening 82, wherein the roller 83 is used for rolling and squeezing a portion to be squeezed in a bending area of the flexible circuit board 6, so that a non-to-be-extruded portion of the bending area forms a raised portion 61 on a side of the capacitive touch film 12 away from the cover plate 11.
[0090] Specifically, the non-to-be-extruded portion refers to the portion of the bending area other than the to-be-extruded portion. A roller 83 is provided in the mounting opening 82 for rolling, and the rolling roller 83 can extrude the to-be-extruded portion of the bending area, so that the flexible circuit board 6 on both sides of the to-be-extruded portion can be better attached or bonded, and at the same time, the non-to-be-extruded portion of the bending area is not extruded, and a convex portion 61 is formed.
[0091] In the present application, by rolling the roller 83 to squeeze the part to be squeezed, the space occupied by the raised portion 61 can be reduced as much as possible to reduce the installation space. The roller 83 squeezes each cable on the flexible circuit board 6 with the same force, so that the bending force of each cable on the flexible circuit board 6 is the same, so that the length and angle of the cable after folding are almost the same, ensuring the neatness of the cable after folding, and preventing the cable from having different lengths. In addition, by using the roller 83 to squeeze each wire of the flexible circuit board 6 at the same time, the bending can be completed in only 10 seconds, which can improve the bending efficiency of the flexible circuit board 6.
[0092] In some embodiments, the portion to be extruded in the bending area is provided with the second adhesive member 7, see Fig.15 As shown, in actual use, the part to be extruded is extruded by the rolling roller 83, so that the second adhesive 7 is connected to the flexible circuit board 6 on both sides opposite to the bending area. At the same time, the part of the bending area not to be extruded (that is, the position where the second adhesive 7 is not set in the bending area) is not extruded, and a protrusion 61 will be formed.
[0093] In some embodiments, the side walls opposite to the mounting opening 82 are each provided with a first mounting hole 811, and mounting portions 831 are provided at both ends of the roller 83. The two mounting portions 831 correspond one-to-one to the two first mounting holes 811, and the mounting portions 831 extend into the corresponding mounting holes so that the roller 83 can roll relative to the mounting opening 82, thereby facilitating rolling and extrusion of the roller 83.
[0094] In some embodiments, a second mounting hole 812 is further opened on the base 81, and the second mounting hole 812 is connected with the first mounting hole 811. The flexible circuit board mounting fixture 8 also includes an elastic member 85 and a fastener 84 located in the second mounting hole 812, one end of the fastener 84 is located outside the second mounting hole 812, and the other end extends into the second mounting hole 812 and is threadedly connected to the mounting portion 831, and the elastic member 85 is sleeved on the outer wall of the fastener 84.
[0095] Specifically, the fastener 84 is used to fix the roller 83 and the elastic member 85. The fastener 84 is threadedly connected to the mounting portion 831. The elastic member 85 is sleeved on the outer wall of the fastener 84, so that in actual use, the pressure of the elastic member 85 on the roller 83 can be adjusted by the locking depth of the fastener 84. Exemplarily, the fastener 84 can be a screw, a bolt, etc.
[0096] The elastic member 85 is used to apply pressure to the roller 83 under the pressure of the fastener 84, so that the roller 83 can press the bending area of the flexible circuit board 6 under a certain pressure. At the same time, the pressure of the elastic member 85 on the roller 83 can be adjusted by adjusting the locking depth of the fastener 84, and then the pressure applied by the roller 83 to the bending area can be adjusted to ensure that the roller 83 can press the part to be pressed in the bending area, and at the same time, it will not cause excessive pressing on the flexible circuit board 6, so as to avoid damage to the flexible circuit board 6. Exemplarily, the elastic member 85 can be a spring.
[0097] The roller 83 can roll along the side of the capacitive touch film 12 away from the cover plate 11 under the push of external force, and at the same time, under the action of the elastic member 85 and the fastener 84, directly apply pressure to the part to be squeezed in the bending area of the flexible circuit board 6 to achieve squeezing of the area to be squeezed.
[0098] In some embodiments, the side walls opposite to the mounting opening 82 are provided with support grooves 813, and the support grooves 813 are used to engage with the cover plate 11, so that the cover plate 11 can support the flexible circuit board mounting jig 8. At the same time, the flexible circuit board mounting jig 8 can move from the edge of the cover plate 11 toward the inside of the cover plate 11 under the push of external force, so as to drive the roller 83 to roll along the capacitive touch film 12.
[0099] For specific implementation, see Fig.16 and Fig.17 First, manually remove the free end of the flexible circuit board 6 that is not connected to the capacitive touch film 12 from Fig.11 Bend to the position shown Fig.12 Position shown.
[0100] Then, the support groove 813 of the flexible circuit board installation jig 8 is clamped on the cover plate 11, so that the roller 83 is on the side of the capacitive touch film 12 away from the cover plate 11, and the flexible circuit board 6 is located in the middle position of the roller 83. Check the downward pressure of the roller 83 squeezing the flexible circuit board 6. If the downward pressure is found to be too large, tighten the fasteners 84 on the left and right sides, increase the stroke of the elastic member 85, and reduce the spring force. Along the manual pushing direction Q, the flexible circuit board installation jig 8 is continuously pushed toward the display screen 1, and the roller 83 squeezes the area to be squeezed of the flexible circuit board 6, so that the flexible circuit boards on the opposite sides of the area to be squeezed are tightly attached or the second adhesive 7 of the area to be squeezed adheres the flexible circuit boards on both sides of the area to be squeezed. The roller 83 is continuously pushed until the area to be squeezed is completely rolled and squeezed. At this time, the jig is withdrawn to complete the bending process of the flexible circuit board 6. The L-shaped cables on the other two sides are folded in the same way.
[0101] In the present application, the flexible circuit board 6 is bent by the pressing of the roller 83, and the pressing force of the roller 83 is continuously adjusted by the elastic member 85 to prevent damage to the flexible circuit board 6 due to excessive pressure, and the elastic force of the elastic member 85 can be adjusted by the locking depth of the fastener 84, which can adapt to the folding of different cables, thereby improving the compatibility of the fixture to a greater extent. The rolling of the roller 83 to complete the folding of the cable improves the quality and efficiency of the operator's folding of the cable.
