As a part of mounting technology, reflow soldering process technology and equipment have also been developed accordingly and are increasingly widely used.

[0003] In the existing welding process for automobile headlight connectors, floating welding is prone to occur in automobile headlight connectors during automatic welding, especially when there are other parts (other mounted connectors or welding harnesses, etc.). The main reason is that the harness is easy to shake on the jig. This interference will cause the PCBA connector to shake and displace, and finally lead to the inability to control the welding accuracy of the automobile headlight connector and a high rate of non-compliance with production capacity. Therefore, a jig for improving the welding accuracy of automobile headlight connectors is proposed. Utility Model Content

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0028] like Figure 1 As shown, a jig for improving the welding accuracy of automobile headlight connectors in this embodiment is applied to a soldering machine, and includes a base 1, a tray 2 and at least one set of wire harness components 3, wherein the tray 2 is fixedly arranged on the base 1, and the tray 2 is used to place the PCBA connector 5 to be soldered. Considering that the wiring 6 of the PCBA connector 5 to be soldered is prone to empty soldering due to shaking, the wire harness component 3 is detachably arranged on the base 1, and is used to lock the wiring 6 of the PCBA connector 5 to be soldered.

[0029] Further explanation, such as Figure 1 As shown, a receiving cavity 4 is provided on the tray 2, and the receiving cavity 4 is used for clamping and accommodating the PCBA connector 5 to be soldered. The clamping of the PCBA connector 5 to be soldered by the receiving cavity 4 can ensure the stability of the PCBA connector 5 to be soldered, limit the shaking of the PCBA connector 5 to be soldered, ensure the welding accuracy, and avoid empty soldering. Figure 4 As shown, the wire harness assembly 3 includes two groups of wire harness lines 31, and the wire harness lines 31 are fixed to the base 1 by bolts, for example. A wire harness slot 32 is formed between the two groups of wire harness lines 31. The wire harness assembly 3 locks the wiring 6 of the PCBA connector 5 to be soldered through the wire harness slot 32, thereby limiting the shaking of the wiring 6, ensuring the welding accuracy, and avoiding empty welding.

[0030] In addition, it should be noted that the base 1 and the tray 2 are preferably made of fr4 fiberglass board, which has good insulation and high temperature resistance properties and is suitable for welding processing.

[0031] In one embodiment, if Figure 2As shown, the jig for improving the welding accuracy of the automobile lamp connector also includes an upper cover 7, which is magnetically connected to the tray 2. The upper cover 7 can locally press the PCBA connector 5 to be soldered, and the local refers to the location on the surface of the PCBA connector 5 to be soldered that does not need to be processed.

[0032] Specifically, Figure 1-3 As shown, both the upper cover 7 and the tray 2 are provided with assembly holes, in which magnets 8 are fixed, and the upper cover 7 and the tray 2 are fixed by the magnets 8. In addition, a positioning hole is fixed on the upper cover 7, and a positioning column is fixed on the tray 2. The positioning column and the positioning hole are matched, so as to facilitate the assembly of the upper cover 7. Both the upper cover 7 and the tray 2 are engraved with anti-fool marks 9, and workers do not need to read the instruction manual, thereby reducing the placement and overall assembly time.

[0033] Considering that the thickness of the wire 6 of the PCBA connector 5 to be soldered is different, in order to limit the position of the wire 6 of different thicknesses, as shown in FIG. Figure 4 and 5 As shown, a plurality of bolt holes 24 distributed linearly are provided on the base 1. By driving bolts into corresponding bolt holes 24, the position of the harness wires 31 can be adjusted, and the width of the harness slots 32 between the two groups of harness wires 31 can be controlled to accommodate the wiring 6 of the PCBA connectors 5 to be soldered of different thicknesses.

[0034] To prevent the wiring 6 of the PCBA connector 5 to be soldered from being higher than the upper surface of the tray 2, Figure 1 As shown, in a certain embodiment, a wire passing groove 21 is provided on the tray 2, the wire passing groove 21 is communicated with the accommodating cavity 4, and the height of the wire passing groove 21 is greater than the diameter of the wiring 6 of the PCBA connector 5 to be soldered, ensuring that the horizontal height of the wiring 6 of the PCBA connector 5 to be soldered will not be equal to the horizontal height of the upper surface of the tray 2, thereby avoiding the wiring 6 from interfering with the welding.

[0035] like Figure 1 , 3 As shown in 5, considering that the accommodating cavity 4 sometimes needs to process two groups of PCBA connectors 5 to be soldered, the accommodating cavity 4 includes two groups of placement cavities 41, and the two groups of placement cavities 41 are respectively used to accommodate the two groups of PCBA connectors 5 to be soldered, and the sizes and shapes of the two groups of placement cavities 41 are different, which is convenient for distinguishing and accommodating and not easy to confuse.

[0036] Further explanation, such as Figure 1As shown, when there are two groups of placement cavities 41, the number of PCBA connectors 5 and wiring 6 are both two groups, that is, one wiring 6 is needed between the two groups of PCBA connectors 5. In order to limit the one wiring 6 used between the two groups of PCBA connectors 5, a wire harness groove 22 is also provided on the tray 2. The wire harness groove 22 connects the two groups of placement cavities 41, and the wire harness groove 22 is used to accommodate the wiring 6 of the PCBA connector 5.

[0037] It should be noted that if Figure 1 , 3 As shown in FIG. 6 , there are card cavities 23 on both sides of the wire harness groove 22 , and the card cavities 23 are used to card the wiring 6 of the PCBA connector 5 to limit the swing of the wiring 6 of the PCBA connector 5 .

[0038] The number of the accommodating cavities 4 is not less than one group, so that the tray 2 can be clamped and accommodate multiple groups of PCBA connectors 5 to be soldered, such as Figure 1 As shown, the number of the accommodating chambers 4 is preferably four groups.

[0039] When in use, the anti-fool mark 9 facilitates the clamping and accommodation of the PCBA connector 5 to be soldered, and facilitates the assembly of the upper cover 7, while the accommodating cavity 4 clamps and accommodates the PCBA connector 5 to be soldered, ensuring the stability of the PCBA connector 5 to be soldered, and cooperates with the wire harness assembly 3 to lock the wire 6 using the wire harness slot 32 between the two sets of wire harness lines 31 to avoid shaking and interference of the wire 6, thereby controlling and improving the welding accuracy.

[0040] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
