[0002] Flexible circuit board or FPC soft cable is a kind of flexible printed circuit board. Many electronic devices, such as cameras, LCDs, etc., are connected to circuit boards by cables. Since the gold fingers of the cable are very thin, usually the width of each gold finger is as small as 0.3mm and the spacing is as small as 0.5mm, the operator needs to align the cable very accurately when soldering it to the circuit board.

[0003] However, since the flexible cable is relatively soft, the two welding components on the flexible cable are in irregular states, making manual welding difficult. After welding, the welding points cannot be guaranteed to be concentric, resulting in low yield and low efficiency.

[0004] In order to solve the positioning problem, the prior art uses PIN pin positioning welding. However, the welding part of the flexible flat cable is easily adhered to the PIN pin and is difficult to remove.

[0031] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0032] Reference Figure 1 As shown, the utility model discloses a welding fixture, comprising: a carrier 1, a bottom plate 2 and a material taking column 3, wherein: the carrier 1 is used to carry the components to be welded, referring to Figure 2 As shown, a plurality of positioning through holes 11 are provided on the carrier 1, and the bottom plate 2 is arranged below the carrier 1. Figure 3As shown, a positioning PIN needle 21 extending toward the carrier 1 is provided on the bottom plate 2. When the carrier 1 and the bottom plate 2 are attached, the positioning PIN needle 21 passes through the positioning through hole 11, and the positioning PIN needle 21 can cooperate with the component to be welded to position the component to be welded. For example, in this embodiment, the component to be welded is a flexible flat cable, and a positioning PIN needle 21 is provided. The N pin 21 passes through two positions on the flexible flat cable, which can realize concentric welding of the flexible flat cable components, solve the problem of eccentric welding of the flexible flat cable components, and improve the yield and efficiency; a material extraction through hole 22 is opened on the base plate 2, and the material extraction column 3 is arranged under the carrier 1 and connected to the carrier 1, and the material extraction column 3 passes through the material extraction through hole 22, and the material extraction column 3 can drive the carrier 1 to move relative to the base plate 2, and under the drive of the material extraction column 3, the carrier 1 and the base plate 2 can be driven to separate, so that the positioning PIN pin 21 is taken out from the positioning through hole 11. After the welding of the flexible flat cable is completed, the welding fixture only needs to support the material extraction column 3. Under the action of gravity, the base plate 2 will be away from the carrier 1, so that the positioning PIN pin 21 can be automatically separated from the product without power, thereby solving the problem of adhesion and difficulty in extracting materials after welding.

[0033] Specifically, in this embodiment, in order to fix the component to be welded in the carrier 1, refer to Figure 2 As shown, the carrier 1 is provided with a contoured groove 12 for placing the component to be welded, and the shape of the contoured groove 12 is the same as the shape of the component to be welded. The component to be welded is placed in the contoured groove 12, and the contoured groove 12 can limit and fix the component to be welded to ensure that its position is fixed during welding.

[0034] Furthermore, in this embodiment, in order to improve the application efficiency of the jig, a plurality of profiling grooves 12 are provided in the carrier 1, that is, a plurality of components to be welded can be carried in one jig, and the plurality of components to be welded are positioned by the jig. Corresponding to the number of the profiling grooves 12, a plurality of positioning PIN needles 21 are also provided on the bottom plate 2, which can position the components to be welded in each profiling groove 12. After welding is completed, the synchronous separation of the plurality of components to be welded and the positioning PIN needles 21 is achieved by moving the bottom plate 2 and the jig away from each other, thereby further improving the use efficiency of the jig;

[0035] Specifically, a plurality of contoured grooves 12 are distributed in a rectangular array in the carrier 1, which also facilitates the use of welding equipment to weld each component to be welded, that is, by setting the moving path of the welding head of the welding equipment, automatic welding of the components to be welded can be achieved.

[0036] Reference Figure 3As shown, in the present embodiment, two types of positioning PIN pins 21 are provided, namely, product positioning PIN pins 211 and welding positioning PIN pins 212. Compared with the positioning PIN pins 21 in the prior art, when welding two components, the welding position is only fixed by the positioning PIN pins 21. In the present embodiment, product positioning PIN pins 211 and welding positioning PIN pins 212 are used, and not only the positions of the two components are positioned at the welding position by the welding positioning PIN, but also the placement positions of the two components are positioned by the product positioning PIN pins 211. In this way, the method of determining a unique straight line by two points can more accurately determine the positional relationship between the two components and ensure the accuracy of the welding position.

[0037] Specifically, in this embodiment, in order to cooperate with the use of the positioning PIN needle 21, a positioning hole is opened in the component to be welded, and the positioning hole is matched with the positioning PIN needle 21. The positioning PIN needle 21 passes through the positioning hole to determine a unique position relationship. When the positioning PIN needle 21 passes through the positioning holes of the two welding components in turn, and then the two components are welded, the concentricity of the positioning holes of the two components can be fully guaranteed, thereby ensuring the accuracy of the welding positions of the two components.

[0038] In other embodiments, according to the form of the positioning PIN needle 21, the component to be welded can also be provided with other features to cooperate with the positioning PIN needle 21, such as: the form of protrusion and groove cooperation, etc., as long as it can be determined that the component to be welded and the positioning PIN needle 21 have a unique cooperation and positioning relationship.

[0039] Reference Figure 4 As shown, in the present embodiment, in order to support the material taking column 3 to pass through the base plate 2 and slide relative to the base plate 2, a bearing 4 for the material taking column 3 to pass through is provided on the base plate 2, and the material taking shaft is guided and supported by the bearing 4, so that the material taking column 3 is limited to slide in the bearing 4, and the direction of relative movement between the base plate 2 and the carrier 1 can be determined, thereby determining the direction of the positioning PIN needle 21 when demolding, and preventing the positioning PIN needle 21 from moving and damaging the welding quality of the welding position.

[0040] In one embodiment of the utility model, two material taking columns 3 are set to jointly support the carrier 1. In other embodiments, different numbers of material taking columns 3 can also be set according to the size of the base plate 2 to ensure the stability when the base plate 2 and the carrier 1 are separated. For example, when the area of ​​the base plate 2 is small, one material taking column 3 can be set at the center position of the base plate 2 to complete the separation drive. When the area of ​​the base plate 2 is large, four material taking columns 3 can also be set at the four corners of the base plate 2 to jointly support the separation drive of the base plate 2 and the carrier 1.

[0041] Reference Figure 5 As shown, during welding, in order to further fix the position of the component to be welded on the carrier 1, the welding fixture of the utility model further includes a cover plate 5, and the cover plate 5 is buckled and arranged above the carrier 1 corresponding to the bottom plate 2. After the component to be welded is placed on the carrier 1, the cover plate 5 is buckled and arranged above the carrier 1. The cover plate 5 can press and fix the component to be welded on the carrier 1, and can ensure that during the welding process, even if it is subjected to large vibration, the position of the component to be welded remains unchanged, and the quality of welding can be guaranteed;

[0042] At the same time, in order not to affect the normal welding action, a welding through hole 51, i.e., an avoidance hole, is provided on the cover plate 5 at the position corresponding to the element to be welded, and the welding equipment is arranged to pass through the welding through hole 51 to weld the designated position of the element to be welded.

[0043] Reference Figure 6 and Figure 7 As shown, in order to cooperate with the separation of the carrier 1 and the base plate 2 after welding by the welding jig described in this embodiment, the utility model also provides a material collection plate 6, and the material collection plate 6 is provided with a support column 61 and a material collection platform 62. The welding jig is placed on the material collection plate 6, and the support column 61 is in contact with the base plate 2. The material collection column 3 can be inserted into the material collection platform 62. The material collection platform 62 pushes the material collection column 3 to drive the carrier 1 and the base plate 2 to move relative to each other, so that the positioning PIN needle 21 is taken out from the positioning through hole 11. In this way, after the welding is completed, it is only necessary to place the welding jig on the material collection plate 6. Under the action of gravity, the base plate 2 will move away from the carrier 1, so that the positioning PIN needle 21 can be automatically separated from the product without power, thereby solving the problem of adhesion and difficulty in material collection after welding.

[0044] Specifically, on the basis of the above embodiments, the utility model discloses a welding device, including: a welding gun and a welding table, wherein the welding table can carry the welding jig.

[0045] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
