[0036] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0037] This embodiment provides a bending fixture for ribbon cables (hereinafter referred to as bending fixture), such as Figure 1 and Figure 2 As shown, the bending fixture includes a base 1 and a flipping assembly 3. A first fixing seat 11 is provided on the base 1, which can fix an electronic product. The electronic product is connected to a ribbon cable 100, and the free end 101 of the ribbon cable 100 extends out of the electronic product. The flipping assembly 3 is provided on the base 1. The flipping assembly 3 includes a flipping member 32 and a rotating shaft 33. A fixing member 200 is provided on the flipping member 32. The flipping member 32 has an adsorption hole 323 to adsorb the fixing member 200. The flipping member 32 rotates along the rotating shaft 33 to have a first position and a second position. When the flipping member 32 is in the first position, the free end 101 is located on the fixing member 200. When the flipping member 32 is in the second position, the fixing member 200 bends the ribbon cable 100 and fixes the free end 101 of the ribbon cable 100 to the electronic product.

[0038] In this bending fixture, the first fixing seat 11 of the base 1 is used to fix the electronic product, and the electronic product is connected to a ribbon cable 100. The free end 101 of the ribbon cable 100 extends out of the edge of the electronic product. When the flipping member 32 of the flipping assembly 3 rotates from the first position to the second position, it drives the ribbon cable 100 to bend around the pressure rod 22 and is fixed to the electronic product by the fixing member 200. In this embodiment, the fixing member 200 is a ribbon cable film with adhesive properties. When the ribbon cable film rotates to the second position with the flipping member 32, it is pressed against the electronic product by the flipping member 32 and adhered to the electronic product through adhesiveness, thereby fixing the ribbon cable 100.

[0039] In this embodiment, the electronic product is described using screen 300 as an example.

[0040] In order to ensure that the screen 300 is positioned accurately and stably on the first fixed base 11, the first fixed base 11 is provided with a plurality of limiting blocks 12. The plurality of limiting blocks 12 are arranged around the screen 300 in the circumferential direction and position the screen 300.

[0041] During the bending process, the ribbon cable 100 is prone to damage due to inconsistent bending positions or excessively small bending radii, affecting production efficiency and costs. For example... Figures 1-3 As shown, to solve the above problems, the bending fixture also includes an auxiliary component 2. The auxiliary component 2 includes a pressure rod 22, which is positioned above the ribbon cable 100. When the flipping component 32 is in the second position, the fixing component 200 bends the ribbon cable 100 around the pressure rod 22, thereby bending the ribbon cable 100 in a fixed position and ensuring a sufficient bending radius, thus avoiding damage to the ribbon cable 100, improving production efficiency and reducing costs.

[0042] In this embodiment, the pressure rod 22 can move along the first direction (X direction in the figure) to press against or avoid the ribbon cable 100. When the free end 101 of the ribbon cable 100 is fixed to the screen 300 by the fixing member 200, the ribbon cable 100 is equivalent to being wound around the pressure rod 22. At this time, the pressure rod 22 can be pulled out by moving along the first direction, so that the operator can take out the screen 300.

[0043] Preferably, the auxiliary component 2 further includes a second fixed base 21 and a rotating arm 23. The second fixed base 21 is disposed on the base 1, and the rotating arm 23 is rotatably connected to the second fixed base 21. The pressure rod 22 is movable along the first direction and disposed on the rotating arm 23. This structure allows the operator more space to place and retrieve the screen 300. When it is necessary to place the screen 300 on the first fixed base 11 or remove it from the first fixed base 11, the rotating arm 23 rotates and moves the pressure rod 22 away from the screen 300. When it is necessary to bend the ribbon cable 100, the rotating arm 23 rotates and moves the pressure rod 22 closer to the screen 300, and then moves the pressure rod 22 along the first direction so that the pressure rod 22 is positioned above the ribbon cable 100.

[0044] like Figure 3 As shown, the auxiliary component 2 also includes a limiting structure 24, which includes a first limiting part 241, a second limiting part 242, and a sliding rod 243 connecting the first limiting part 241 and the second limiting part 242. The sliding rod 243 is slidably disposed on the rotating arm 23 in a first direction, and the rotating arm 23 is disposed between the first limiting part 241 and the second limiting part 242. The pressure rod 22 is connected to the limiting structure 24.

[0045] The limiting structure 24 can slide relative to the rotating arm 23 via the slide bar 243, thereby driving the pressure bar 22 to move. This allows the pressure bar 22 to be positioned above the cable 100 to assist in bending the cable 100, and also allows the pressure bar 22 to move out of the cable 100's range after bending. Moreover, the limiting structure 24 limits both positions of the pressure bar 22, which can improve the operator's efficiency in moving the pressure bar 22 while ensuring movement accuracy, making operation easier.

[0046] like Figure 3 As shown, the rotating arm 23 includes a rotating part 231 and an adjusting part 232. The rotating part 231 is rotatably connected to the second fixed seat 21. The pressure rod 22 is disposed on the adjusting part 232. The adjusting part 232 and the rotating part 231 are radially movable to adjust the position of the pressure rod 22 relative to the cable 100.

[0047] By adjusting the relative movement of the rotating part 231 and the adjusting part 232, the position of the pressure rod 22 in the second direction when it is above the cable 100 can be adjusted, which means adjusting the bending position of the cable 100, thus improving the applicability of the bending fixture. It is worth noting that the adjusting part 232 has a slotted hole, and the adjusting part 232 is connected to the rotating part 231 by a screw passing through the slotted hole, so as to adjust the relative position of the rotating part 231 and the adjusting part 232.

[0048] Furthermore, the second fixing seat 21 can rotate relative to the base 1 to adjust the angle of the pressure rod 22, so that the bending fixture can be adapted to the screen 300 where the ribbon cable 100 is angled. Figure 3 As shown, specifically, the second fixing seat 21 has a first fixing hole 211 and a second fixing hole 212. The second fixing hole 212 is an arc-shaped hole with the first fixing hole 211 as the center. The screw fixes the second fixing seat 21 to the base 1 through the first fixing hole 211 and the second fixing hole 212. Therefore, the second fixing seat 21 can rotate around the first fixing hole 211 to adjust the angle of the pressure rod 22.

[0049] like Figure 4 and Figure 5 As shown, the flip assembly 3 includes a third fixing base 31 and a flip block 37. The third fixing base 31 is disposed on the base 1, and the rotating shaft 33 passes through the flip block 37 and is rotatably connected to the flip block 37. The flip member 32 is fixedly connected to the flip block 37. The third fixing base 31 can fix the flip assembly 3 as a whole on the base 1, so that the flip assembly 3 and the first fixing base 11 have the same reference body, thereby ensuring the stability of the relative position of the flip member 32 and the screen 300, so that the flip member 32 is in the same state every time the screen 300's ribbon cable 100 is bent.

[0050] To facilitate operation, a handle 38 is provided on the flip block 37, which allows the operator to drive the flip block 37 to rotate.

[0051] It's worth noting that the location of the flex cable 100 varies depending on the type of screen (300). For example... Figure 1 and Figure 2As shown, in order to improve the applicability of the bending fixture, the axial direction of the rotating shaft 33 is set along the first direction, and the third fixed seat 31 can move along the second direction (Y direction in the figure). That is, by moving the third fixed seat 31, the position of the rotation axis of the flipping member 32 can be adjusted to adapt to flipping the ribbon cable 100 in different positions.

[0052] Specifically, the third fixing seat 31 has an oblong hole, and the third fixing seat 31 is fixed by screws passing through the oblong hole, thereby realizing the adjustability of the third fixing seat 31.

[0053] In this embodiment, the flipping member 32 includes a first fixing part 321 and a second fixing part 322 that are spaced apart. Both the first fixing part 321 and the second fixing part 322 are provided with adsorption holes 323 to adsorb the fixing member 200. When the flipping member 32 is in the second position, the pressure rod 22 is located between the first fixing part 321 and the second fixing part 322.

[0054] This structure allows the flip member 32 to avoid the pressure bar 22 so that the fixing member 200 can be directly pressed against the screen 300, which increases the pressure and thus improves the reliability of fixing the free end 101 of the cable 100. At the same time, it also allows the fixing member 200 to be fixed on both sides of the pressure bar 22, increasing the connection area and preventing it from coming apart.

[0055] Preferably, the fixing member 200 includes an adhesive portion 201. When the flipping member 32 presses the fixing member 200 against the screen 300, both the first fixing portion 321 and the second fixing portion 322 press against the adhesive portion 201 to ensure that the fixing member 200 is adhered to the screen 300 on both sides of the pressure rod 22.

[0056] like Figure 4 and Figure 5 As shown, the flipping assembly 3 also includes a positioning pin 34, which is telescopically mounted on the flipping component 32. The fixing component 200 has a positioning hole. When the positioning pin 34 extends out of the flipping component 32, it passes through the positioning hole to position the fixing component 200. The positioning pin 34 can position the fixing component 200, ensuring that the free end 101 of the ribbon cable 100 is in the same position when the fixing component 200 is attached. The telescopic movement of the positioning pin 34 can avoid the pressure rod 22, preventing the positioning pin 34 from abutting against the pressure rod 22 and causing the flipping component 32 to fail to flip into place.

[0057] Preferably, the flip assembly 3 further includes an elastic element 35, which is configured to drive the positioning pin 34 to extend out of the flip assembly 32. When the flip assembly 32 is in the first position, the elastic element 35 drives the positioning pin 34 to extend out of the flip assembly 32 to position the fixing member 200, ensuring the accurate position of the fixing member 200. When the flip assembly 32 rotates to the second position, the positioning pin 34 can compress the elastic element 35 and retract, avoiding the pressure bar 22 while ensuring that the flip assembly 32 can press the fixing member 200 against the screen 300.

[0058] In this embodiment, the flipping member 32 is provided with a stepped hole 324, which includes a large diameter section and a small diameter section. The positioning pin 34 includes a positioning part 341 and a limiting boss 342. The positioning part 341 passes through the small diameter section, and the limiting boss 342 is slidably disposed in the large diameter section. The elastic member 35 abuts against the limiting boss 342 and drives the limiting boss 342 to move toward the step between the large diameter section and the small diameter section.

[0059] The step between the large diameter section and the small diameter section can limit the positioning pin 34, so that when the flipping part 32 is in the first position, the positioning pin 34 is driven by the elastic part 35 to abut against the step, which can both prevent the positioning pin 34 from dislodging from the step hole 324 and ensure the relative stability between the flipping part 32 and the positioning pin 34.

[0060] Preferably, the flipping member 32 and the flipping block 37 are connected by a flipping arm 39. The large-diameter section of the stepped hole 324 of the flipping member 32 extends to the surface of the flipping member 32. The flipping arm 39 is fixedly connected to the flipping member 32 and blocks the large-diameter section. The elastic member 35 is disposed in the large-diameter section, and the two ends of the elastic member 35 abut against the limiting boss 342 and the flipping arm 39, respectively.

[0061] It's worth noting that the 300mm screen is relatively fragile. For example... Figure 1 , Figure 2 and Figure 4 As shown, to prevent the flip component 32 from cracking the screen 300, the flip assembly 3 also includes a limiting component 36. The limiting component 36 is connected to the flip component 32. When the flip component 32 is in the second position, the limiting component 36 abuts against the base 1. The limiting component 36 can limit the position of the flip component 32, ensuring that the pressure exerted by the flip component 32 on the screen 300 is sufficient to bond and fix the fixing component 200, thus avoiding excessive pressure that could affect the normal use of the screen 300.

[0062] Preferably, the position of the limiting member 36 relative to the flipping member 32 is adjustable. That is, the limiting member 36 can adjust the relative distance between the flipping member 32 and the screen 300 when the flipping member 32 is in the second position by adjusting the position, thereby adjusting the pressure of the flipping member 32 on the fixing member 200.

[0063] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
