[0051] According to an embodiment of the utility model, on the one hand, an auxiliary tool for chip welding is provided, the auxiliary tool is used to weld the chip to be welded and the wire harness to be welded together, and the chip to be welded is provided with a welding pad and a vent. The auxiliary tool comprises a base 1, a tin-planting plate 2 and a connection component.

[0052] Specifically, in the embodiment of the utility model, the base 1 is provided with a chip slot 11 and a harness slot 12, and the chip slot 11 and the harness slot 12 are connected to each other. The chip slot 11 is used to place the chip 8 to be welded, and the harness slot 12 is used to place the harness 9 to be welded.

[0053] Further, in the embodiment of the utility model, the tin-planting plate 2 is arranged on the base 1. The tin-planting plate 2 is provided with a tin-planting hole 7, and when the tin-planting plate 2 covers the chip slot 11 and the harness slot 12, the tin-planting hole 7 corresponds to the position of the pad 81 of the chip 8 to be welded in the chip slot 11. The tin-planting plate 2 has a first position covering the chip slot 11 and the harness slot 12, and a second position opening the chip slot 11 and the harness slot 12.

[0054] That is to say, in actual operation, the tin-planting plate 2 is first moved to the second position, and then the chip 8 to be welded and the wire harness 9 to be welded are placed on the chip slot 11 and the wire harness slot 12 of the base 1. Then the tin-planting plate 2 is moved to the first position, and then the tin-planting operation and welding operation can be performed. Thus, the chip 8 to be welded and the wire harness 9 to be welded are welded together.

[0055] Further, in the embodiment of the utility model, the connecting component connects the tin-planting plate 2 to the base 1. For example, one end of the connecting component can be connected to the tin-planting plate 2, and the other end of the connecting component can be connected to the base 1, so that the tin-planting plate 2 and the base 1 are connected together.

[0056] In the embodiment of the utility model, the connection assembly can be composed of multiple connection plates and multiple connection rods, and of course, it can also be composed of a combination of connection plates and connection rods. This embodiment is only an example of the composition of the connection assembly, but it is not limited to this.

[0058] Specifically, in the embodiment of the utility model, for the movable connection method, the connection component can adopt the method of screws and screw holes, the method of snap-on slots, or the method of magnetic attraction.

[0059] The following is an example of a movable connection method. For example, additional fixing plates can be set around the edge of the base 1. The technicians in this field can change the number of fixing plates according to the actual situation, to 1, 2, 3, 4, etc., and then open a screw hole on the fixing plate, and then open another screw hole on the tin-planting plate 2 at the position corresponding to the screw hole, and then pass the screw through the screw hole on the fixing plate and the screw hole on the tin-planting plate 2 in sequence to connect the base 1 with the tin-planting plate 2. Furthermore, when fixing by means of buckles and slots, additional buckles can be set around the edge of the base 1. The technicians in this field can change the number of buckles according to the actual situation, to 1, 2, 3, 4, etc., and then open a slot on the tin-planting plate 2 that can work with the buckle at the position corresponding to the buckle, and then the buckle on the base 1 is directly embedded in the slot on the tin-planting plate 2, so as to connect the base 1 with the tin-planting plate 2. When fixing by magnetic attraction, additional magnetic sheets can be arranged around the edge of the base 1. The technicians in this field can change the number of magnetic sheets according to the actual situation, 1, 2, 3, 4, etc., and then open the opposite magnetic sheets that can be attracted to the magnetic sheets at the positions corresponding to the magnetic sheets on the tin-planting plate 2. Then, the magnetic sheets on the base 1 are directly aligned with the opposite magnetic sheets embedded in the tin-planting plate 2, so that the base 1 and the tin-planting plate 2 are magnetically connected.

[0060] Of course, this embodiment is only an example of a fixed connection method and a movable connection method, but it is not limited to this. Those skilled in the art can make changes according to actual conditions as long as the same technical effect can be achieved.

The connection column 3 is interference fit with the first connection hole 21 and the second connection hole 13, and the first connection hole 21 and the second connection hole 13 can stably clamp the connection column 3.

[0064] In actual operation, the compression spring 4 is put on the connecting column 3, and inserted into the first connecting hole 21 and the second connecting hole 13 in sequence, and then the compression spring 4 is assembled on the base 1. When starting welding, the connecting column 3 is first loosened outward to move the tin-planting plate 2 to the second position, and then the chip 8 to be welded and the wire harness 9 to be welded are placed on the chip slot 11 and the wire harness slot 12 of the base 1. After moving the tin-planting plate 2 to the first position, the tin-planting plate 2 is fixed to the base 1 through the connecting column 3. After that, the tin-planting operation and welding operation can be carried out.

[0065] Furthermore, after the tin is implanted through the tin implant hole 7, the connecting column 3 is loosened outward by a certain displacement to ensure that the clamping spring 4 is completely relaxed, and then the tin implant plate 2 is lifted up along the connecting column 3 and rotated 180 degrees, and then the connecting column 3 is inserted downward to make the clamping spring 4 clamp the tin implant plate 2, and then the wiring harness 9 to be welded and the chip 8 to be welded are welded.

[0066] At this time, the soldering plate 2 has been completely placed on one side of the chip slot 11, and the pad 81 of the chip 8 to be welded is completely exposed. After all the chips in the chip slot 11 are welded, the welded chip harness assembly is taken out, and the next batch of harnesses 9 to be welded and the chips 8 to be welded are placed on the base 1 and fixed.

[0067] Then loosen the connecting column 3 outward to completely relax the compression spring 4, and then rotate the tin-planting plate 2 180 degrees around the connecting column 3 to align the tin-planting holes 7 with the pads 81 of the chip 8 to be soldered one by one, and then perform tin-planting, and repeat the above steps for soldering.

[0068] Furthermore, in an optional embodiment, in order to facilitate the operation of technicians, the connecting column 3 can be selected as a threaded column, and the first connecting hole 21 and the second connecting hole 13 can be correspondingly selected as threaded holes that match the threaded column.

The limiting hole 5 is arranged on one of the base 1 and the tin-planting plate 2, and the limiting column 6 is arranged on the other of the base 1 and the tin-planting plate 2, and the limiting hole and the limiting column are arranged correspondingly. For example, the limiting hole 5 can be arranged on the base 1, and then the limiting column 6 is arranged on the tin-planting plate 2, or the limiting hole 5 can be arranged on the tin-planting plate 2, and the limiting column 6 can be arranged on the base 1.

[0071] During actual application, when the tin-planting plate 2 is aligned with the base 1 , the limiting column 6 is inserted into the limiting hole 5 , thereby limiting the tin-planting plate 2 and the base 1 .

In this embodiment, multiple limiting columns 6 may be provided in the circumferential direction of the edge of the base 1, and multiple limiting holes 5 may be correspondingly provided on the tin-planting plate 2, that is, the positions of the limiting holes 5 correspond one to one with the positions of the limiting columns 6.

[0073] For example, in this embodiment, the number of limit posts 6 can be 4, 5, 6, 7, 8, 9, 10, etc. Of course, this embodiment is only an example to illustrate the number of limit posts 6, but does not limit it.
