[0002] In daily life, many electronic products or smart wearable products need to install a flexible printed circuit board (FPC). The flexible printed circuit board is used to connect electrical signals or perform signal connection with the outside world (receiving antenna). However, in electronic products, due to limited space, a flexible printed circuit board FPC with a smaller size can be adopted. After being bent, the occupied space is smaller, which can meet the design requirements.

[0003] After the flexible printed circuit board FPC is bent, it occupies multiple planes; it is also necessary to bond and fit the flexible printed circuit board on multiple surfaces of the housing, so as to realize the assembly of the flexible printed circuit board and the housing.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are one embodiment of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0034] Please refer to Figures 1 to 12 , the present invention provides a fitting device for a flexible printed circuit board and a housing.

[0035] The first implementation mode of the fitting device: The fitting device is for the first flexible printed circuit board 2 as shown in Figure 1 , and only needs to be fitted on both sides, and the fitting method is relatively simple.

[0036] The fitting device includes a frame 1 and a lateral conveying component 3 for laterally conveying the housing 4; further, the lateral conveying component 3 is installed at the bottom of the frame 1, a laterally moving flat plate 5 is installed on the frame 1, a first placing fixture 6 for placing the housing 4 is installed on the laterally moving flat plate 5, the laterally moving flat plate 5 and the first placing fixture 6 move laterally together, move below the loading and picking component 7, and dock with the loading and picking component 7; the loading and picking component 7 is installed on the frame 1; a hollow groove 19 is provided on the frame 1, the loading and picking component 7 moves vertically downward, passes through the hollow groove 19, picks up the housing 4 on the lateral conveying component 3, and at the same time, the first placing fixture 6 moves laterally below the loading and picking component 7, and the loading and picking component 7 places the housing 4 into the first placing fixture 6.

[0037] In other embodiments, the loading and picking component 7 can also be driven by a multi-axis manipulator to drive the loading and picking component 7 to pick up the housing 4 on the lateral conveying component 3 and place it into the first placing fixture 6; wherein, due to the drive of the multi-axis manipulator, the lateral conveying component 3 can be installed on one side of the frame 1, on the right side of the first placing fixture 6, and the loading and picking component 7 realizes automatic loading and unloading under the drive of the multi-axis manipulator.

[0038] Further, a loading and fitting manipulator 9 is also installed on the frame 1; after the housing 4 is placed inside the first placing fixture 6, the loading and fitting manipulator 9 is used to automatically load the bent flexible circuit board 2 and fit it inside the housing 4 in the first placing fixture 6.

[0039] The movement process of the fitting device: First, manually or automatically place the housing 4 on the lateral conveying component 3, and the lateral conveying component 3 automatically laterally conveys the housing 4 and laterally transfers the housing 4 below the loading and picking component 7; second, the loading and picking component 7 moves vertically downward, passes through the hollow groove 19, picks up the housing 4 on the lateral conveying component 3, and moves vertically upward together with the housing 4; third, the first placing fixture 6 moves laterally below the loading and picking component 7, and the loading and picking component 7 moves vertically downward and places the housing 4 in the first placing fixture 6; the first placing fixture 6 places and positions the housing 4; finally, the loading and fitting manipulator 9 adsorbs, transfers, and automatically fits the bent flexible circuit board 2 with the housing 4; it realizes the automatic loading of the flexible circuit board 2 and the housing 4, and also realizes the automatic fitting of the flexible circuit board 2 inside the housing 4, improving the fitting efficiency and fitting consistency.

[0040] Next, the specific structures of each component will be introduced and how to transfer the fitted housing 4 again, transfer it onto the lateral conveying component 3, and the lateral conveying component 3 laterally transfers the fitted housing 4 for unloading.

[0041] As Figure 5 shown, the loading pick-up part 7 is a pneumatic U-shaped claw. A gap is provided in the middle of the pneumatic U-shaped claw for being clamped into the side surface of the housing 4, and the two sides of the pneumatic U-shaped claw are driven by gas to clamp the housing 4. Further, the pneumatic U-shaped claw can be purchased as an existing mature product.

[0042] Furthermore, the loading pick-up part 7 is in transmission connection with a vertical driving assembly 71, and the vertical driving assembly 71 is installed at one end of the frame 1; the vertical driving assembly 71 drives the loading pick-up part 7 to move vertically back and forth for picking up the housing 4 and moving vertically back and forth; the vertical driving assembly 71 can adopt a vertical driving module or a single multi-stage cylinder.

[0043] If a vertical driving module is adopted, its output can be stably controlled to achieve multi-stage output; if a single multi-stage cylinder is adopted, stable multi-stage output can also be achieved; if a single ordinary cylinder is adopted, when placing the housing 4, it is directly released and placed, with a certain distance, resulting in a low placement success rate and a low subsequent qualified rate.

[0044] However, in this embodiment, the vertical driving assembly 71 includes a first vertical cylinder 711 and a second vertical cylinder 712 installed at the end of the first vertical cylinder 711. The first vertical cylinder 711 and the second vertical cylinder 712 are spliced together to achieve multi-stage control. Among them, the first vertical cylinder 711 is installed on the frame 1; the end of the second vertical cylinder 712 is installed with the loading pick-up part 7. Further, during the picking process, the first vertical cylinder 711 drives the second vertical cylinder 712 and the loading pick-up part 7 to move vertically downward to pick up the housing 4 and vertically return to the original position; during the process of placing the housing 4, the second vertical cylinder 712 moves vertically downward to vertically place the housing 4 into the housing 4 to achieve stable placement.

[0045] As Figure 5 shown, the transverse conveying component 3 is a conveyor belt. In addition, the transverse conveying component 3 can also be a chain belt transportation, and is not limited thereto.

[0046] In order to improve the transverse transportation accuracy of the housing 4, as Figure 6As shown, the bottom of the frame 1 is equipped with a first L-shaped bracket 11 installed at the front end and a second L-shaped bracket 12 installed at the rear end, the first L-shaped bracket 11 and the second L-shaped bracket 12 are equipped with a first side limit plate 13 on one side, and a second side limit plate 14 on the other side, and the ends of the first side limit plate 13 and the second side limit plate 14 are provided with an end limit plate 15, the first side limit plate 13 and the second side limit plate 14 are used to limit the left and right sides of the shell 4, and the end limit plate 15 is used to limit the left and right sides of the shell 4. One end of the shell 4 is limited so that the shell 4 can be fixed in a specific position; the end limit plate 15 can also be provided with an induction switch for sensing the shell 4; the first L-shaped bracket 11 and the second L-shaped bracket 12 are used as connecting parts to connect the first side limit plate 13, the second side limit plate 14 and the end limit plate 15 to the frame 1, so that the first side limit plate 13, the second side limit plate 14 and the end limit plate 15 do not contact the conveyor belt, thereby extending the service life and limiting the shell 4 at the same time.

[0047] Furthermore, in order to cooperate with the loading picking piece 7 and facilitate the loading picking piece 7 to clamp the shell 4, the first side limit plate 13 and the second side limit plate 14 are provided with a plurality of first clamping grooves 131 for the loading picking piece 7 to clamp; the loading picking piece 7 is inserted into the first clamping groove 131 to clamp the shell 4.

[0048] like Figure 5 As shown, a transverse moving plate 5 is installed on the upper part of the frame 1, and a first placement fixture 6 is fixedly installed on the transverse moving plate 5. The transverse moving plate 5 moves laterally together with the first placement fixture 6 to move the first placement fixture 6 laterally to the bottom of the loading and picking member 7 and away from the loading and picking member 7; specifically, the transverse moving plate 5 is transmission-connected with a first transverse driving member 51, and the first transverse driving member 51 is installed on the frame 1. The first transverse driving member 51 adopts a transverse driving cylinder. Figure 4 and Figure 5 It can be clearly seen that the first lateral driving member 51 drives the lateral movable plate 5 and the first placement fixture 6 to reciprocate laterally.

The third vertical cylinder 181 drives the first pressing block 182 and the first clamping assembly 17 to move vertically downward to press the housing 4 inside the first placement fixture 6, facilitating subsequent fitting and making the fitting accuracy higher; if the housing 4 is not pressed, direct fitting can be carried out, but the fitting accuracy and effect will be relatively ordinary.

[0052] Further, the first clamping assembly 17 includes a first longitudinal clamping cylinder 171 installed on the first pressing block 182 and first clamping jaws 172 installed on both sides of the first longitudinal clamping cylinder 171; the first longitudinal clamping cylinder 171 drives the first clamping jaws 172 on both sides to clamp the housing 4 inside the first placement fixture 6.

[0053] Even further, as Figure 11 shown; a first pressing block 182 is provided on the inner side of the housing 4, and first clamping jaws 172 are provided on the outer side. The first pressing block 182 and the first clamping jaws 172 cooperate with each other to clamp the housing 4.

[0055] In subsequent embodiments, after the flexible circuit board 2 after bending is fitted to the housing 4, it may not pass through the hollow groove 19 and be placed in the second placement jig 8. After being processed by the second placement jig 8, it is then blanked through the horizontal conveying component 3.
