[0002] FPC is a flexible printed circuit board, which is highly favored for its excellent properties such as light weight, thin thickness, and free bending and folding. It is a printed circuit with high reliability and excellent flexibility made of polyester film or polyimide as the substrate. By embedding the circuit design on the flexible and thin plastic sheet, a large number of precision components can be stacked in a narrow and limited space, thus forming a flexible circuit. The FPC components are soldered or assembled into FPCA, which is assembled using flexible circuit boards. The board has bendability and is used in high-end products such as mobile phones, with high assembly density.

[0035] The invention is further described below with reference to the accompanying drawings and specific embodiments: Example

[0036] See also Figure 1-4 According to an embodiment of the present invention, an FPCA gluing jig includes a base plate 1, a groove 2 is provided at the upper end of the base plate 1, foam 3 is laid on the groove 2, a plurality of through grooves 4 are provided at the upper end of the foam 3, and a card slot 5 corresponding to the through groove 4 is provided at the upper end of the groove 2 for clamping a positioning mechanism 6.

[0037] Through the above-mentioned scheme of the present invention, by opening a groove 2 on one side of the base plate 1 and laying foam 3 in the groove 2, the product can be prevented from directly contacting the surface of the jig during the FPCA production process, thereby protecting the product. The provided card slot 5 can insert the positioning pin 7 into the card slot 5 according to the positioning hole of the product, and the through groove 4 provided in the foam 3 can avoid blocking the positioning pin 7, so that the positioning pin 7 is easy to match the positioning hole on the FPCA, making the jig a universal jig, greatly reducing the cost of the gluing process, and reducing the time required for installing the jig, which can increase the scope of use of the equipment jig and can be used for various product models. Example

[0038] See also Figure 2-3 According to an FPCA glue jig according to an embodiment of the present invention, the positioning mechanism 6 includes a positioning pin 7, a sleeve 8 and a clamping assembly 9. The positioning pin 7 is provided in the slot 5. The outer wall of the lower end of the positioning pin 7 is slidably sleeved with a sleeve 8. A piston 10 is slidably sleeved in the sleeve 8 and fixedly connected to the positioning pin 7. A clamping assembly 9 is provided between the sleeve 8 and the positioning pin 7. The clamping assembly 9 includes a slider 11, a slider 2 12 and a connecting rod 13. The outer wall of the sleeve 8 is provided with a plurality of C-shaped grooves 14. The connecting rods 13 are rotatably connected to the C-shaped grooves 14 through a rotating shaft. The upper end of the connecting rod 13 is hinged to the slider 11 The lower end of the connecting rod 13 is hinged with a slider 2 12, and the upper and lower ends of one side of the slider 11 are processed with bevels. The outer wall of the piston 10 is processed with a trapezoidal groove 15 that cooperates with the slider 11, and an elastic member 16 is provided between the other side of the slider 11 and the inner wall of the C-shaped groove 14. The lower end of the slider 2 12 is processed with a bevel, and a limiting boss 17 that cooperates with the slider 2 12 is fixedly connected in the slot 5. A spring 18 is fixedly provided between the upper end of the piston 10 and the inner wall of the sleeve 8. The outer wall of the positioning pin 7 is fixedly connected to a limiting ring 19, and the limiting ring 19 is located above the sleeve 8.

[0039] The locking cam 17 is engaged with the locking cam 18 and the locking cam 19 is engaged with the locking cam 11. The locking cam 18 is engaged with the locking cam 11 and the locking cam 12. The locking cam 18 is engaged with the locking cam 11 and the locking cam 12 is engaged with the locking cam 11. The limiting boss 17 prevents the housing 8 from moving, thereby causing the piston 10 to continue to move upward on the inner wall of the housing 8, so that the trapezoidal groove 15 opened on the outer wall of the piston 10 contacts the slider 11, and the slider 11 is ejected by the elastic member 16, driving the connecting rod 13 to retract the slider 2 12 into the C-shaped groove 14, thereby separating the housing 8 from the limiting boss 17, so that the positioning pin 7 can be quickly removed, making the assembly and disassembly steps of the positioning pin 7 simpler. When the housing 8 is separated from the limiting boss 17, the piston 10 is pushed downward in the housing 8 by the elastic force of the spring 18, and the upper end of the slider 11 is also processed with an oblique angle, so that the slider 11 will not block the downward movement of the piston 10, so that the piston 10 can be reset in the housing 8, and the limiting ring 19 arranged on the outer wall of the positioning pin 7 can prevent the piston 10 from falling out of the housing 8. Example

[0040] See also Figure 4 According to an embodiment of the present invention, a method for using an FPCA glue jig includes the following steps:

[0041] S101, make the shape of the fixture according to the drawing;

[0042] S102, slotting one side of the jig according to the maximum size of the product;

[0043] S103, a plurality of slots 5 are processed in the slot;

[0044] S104, fixing and connecting the limiting boss 17 in the slot;

[0045] S105, laying foam 3 at the groove;

[0046] S106, the outer wall of the foam 3 is processed with a through groove 4 corresponding to the card slot 5;

[0047] S107, inserting the positioning pin 7 into the card slot 5 according to the positioning hole of the FPCA;

[0048] S108, pressing the housing 8 so that the clamping assembly 9 in the housing 8 engages with the limiting boss 17 to fix the positioning pin 7;

[0049] S109, placing the FPCA product on the foam 3 in the fixture through the robot.

[0050] Through the above method of the present invention, the positioning pin 7 can be fixed at the card slot 5 according to the positioning hole of the FPCA product, so that the clamping component 9 is clamped with the limiting boss 17 to fix the positioning pin 7, so that the fixture can adjust the positioning position according to the shape of the FPCA product, making the application range of the fixture wider and reducing the cost of manufacturing the fixture.

[0051] In order to facilitate understanding of the above technical solutions of the present invention, the working principle or operation mode of the present invention in actual process is described in detail below.

[0052] In actual application, the foam 3 is laid on the bottom plate 1, and then the positioning pin 7 is inserted into the corresponding card slot 5 according to the positioning hole of the FPCA. When the piston 10 contacts the limiting boss 17, the housing 8 is pressed to make the housing 8 slide down, so that the piston 10 moves up in the housing 8, squeezing the slider 11 to retract the slider 11 into the C-shaped groove 14, and the slider 2 12 is pushed out of the C-shaped groove 14 through the connecting rod 13. Then the slider 2 12 contacts the lower end of the limiting boss 17 to clamp the housing 8, so that the positioning pin 7 is fixed. When the positioning pin 7 needs to be removed, it is only necessary to pull the positioning pin 7 so that the positioning pin 7 drives the piston 10 to move upward in the housing 8, thereby making the trapezoidal groove 15 contact the slider 11, and the elastic member 16 pushes the slider 11 to be inserted into the trapezoidal groove 15 to drive the slider 2 12 to retract into the C-shaped groove 14, so that the housing 8 and the limiting boss 17 are no longer stuck, and the housing 8 and the limiting boss 17 are separated, and the provided spring 18 will push the piston 10 to move downward in the housing 8, thereby resetting the piston 10.
