Referring to fig. 1, in a first embodiment of the present invention, a method for welding a charging head is provided, where the charging head includes a charging connector and a welding plate, the charging connector includes a conductive metal material, and charging or signal transmission to a corresponding electronic product is implemented through the conductive metal. The welding plate can be understood as a welding position of the charging connector, the welding plate is used for transmitting power, such as voltage, to the charging connector, and the welding plate can be a soft circuit board or a circuit board with a certain hard material, and the welding method comprises the following steps:
and S10, the positions of the welding plate and the charging connector are close to each other, and a welding gap is formed between the welding plate and the charging connector.
Specifically, the welding plate may be fixed, the charging connector may be moved closer to the welding plate, the charging connector may be fixed, the welding plate may be moved closer to the charging connector, or the welding plate and the charging connector may be moved closer to each other. For example, the charging connector is fixed by the fixing device, and the welding operator directly moves the welding plate or moves the welding plate to the charging connector by the moving device, so that the welding operation is started. When the distance between the welding plate and the charging connector is fixed, the welding plate and the charging connector are fixed in position, so that accuracy deviation cannot occur during welding, and the distance between the welding plate and the charging connector can effectively ensure that the welding tin connects the welding plate and the charging connector together. The welding distance between the welding plate and the charging connector can be adjusted according to the design and use requirements. For example, the width of the welding gap is between 0.05mm and 0.2mm, and when the width of the welding gap is 0.05mm, the positions of the charging connector and the welding plate are more compact, so that the soldering tin can be effectively ensured to be welded and connected with the charging connector and the welding plate. When the width of the welding gap is 0.2mm, the soldering tin is easy to spray, in other words, enough space is available for carrying out the tin spraying operation, and the smooth carrying out of the tin spraying operation is ensured. The width of the welding gap can be 0.1mm, so that the welding connection between the welding plate and the charging connector can be ensured, and enough operation space can be provided for tin spraying operation.
Step S20, spraying molten solder at the welding gap position.
In the related art, solder is generally soldered to a soldering board in advance, and then soldered by melting the solder. As can be seen from step S20, molten solder is directly sprayed onto the solder joint at the position of the solder joint between the solder plate and the charging connector, and the solder joint between the solder plate and the charging connector is realized by air-drying cooling or natural cooling. Therefore, the process of hot melting the soldering tin on the welding plate in advance in the traditional welding mode is reduced, and the operation steps are simple and the welding efficiency is effectively improved when the charging connector is arranged for welding.
In the technical scheme of this embodiment, in the welding gap position department of welded plate and charging connector, spray molten state's soldering tin, avoid among the prior art, with the soldering tin repeated welding reheat process, just can accomplish welding operation through once hot melt to spraying soldering tin, effectively reduced operating procedure, improved welding efficiency.

Through setting up support piece, set up the metal conducting layer at support piece surface, can effectively reduce the quantity of using the metal to this reduce cost. Meanwhile, the material of the supporting piece can be selected from materials with light weight and low processing cost, for example, ABS (Acrylonitrile Butadiene Styrene) plastic, namely acrylonitrile-butadiene-styrene copolymer, or Polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS) and the like. The plastic material is generally lower in weight than the metal of the same volume, and thus the weight of the charging connector can be effectively reduced when one or more of the materials are used. The step S10 of creating a welding gap between the welding plate and the charging connector before the welding plate and the charging connector are positioned close to each other includes:
and S01, injection molding the support, and depositing a conductive layer on the outer surface of the support.
The shape and structure of the support member can be processed according to design requirements, for example, a plate shape or a bent shape with a certain included angle. The material of the support member comprises plastic, the plastic has strong plastic performance, specifically, the plastic is heated to reach the melting point of the plastic, the plastic starts to melt, and the melted plastic is injected into a pre-processing and forming mold to complete the injection molding of the support member.
After injection molding of the support, the conductive layer is deposited by deposition on the outer surface of the support. For example, the conductive layer is formed on the outer surface of the injection molded part by physical vapor deposition or chemical vapor deposition. The material of the conductive layer comprises copper, and the conductive layer can also comprise alloy, wherein the alloy conductive layer has oxidation resistance and good hardness, and the thickness of the conductive layer can be deposited according to the requirements of the use design. For example, the thickness of the conductive layer is between 0.05mm and 0.2 mm. When the thickness of the conductive layer is 0.05mm, the processing steps are simple and easy to realize. When the thickness of the conducting layer is 0.2mm, the conducting layer can play a role in supporting the structure of the conducting layer, and deformation of the conducting layer is avoided. In addition, the thickness of the conductive layer can be 0.1mm, so that the conductive layer can be ensured to be easy to process, and the conductive layer can also support the self structure.
Referring to fig. 3, a third embodiment is proposed on the basis of the second embodiment of the present invention, in which a support is injection molded, and a step S01 of depositing a conductive layer on an outer surface of the support includes:
and S010, injection molding the support piece, and laser molding the conductive layer on the outer surface of the injection molded support piece.
The laser forming comprises a laser direct forming technology (Laser Direct Structuring), namely an LDS technology, which is characterized in that a computer is used for controlling laser movement according to the track of a conductive pattern, and laser is projected onto a molded three-dimensional plastic device to form a circuit pattern within a few seconds. In brief, the technology of plating metal directly on the outer surface of the support member by using laser technology is adopted. The LDS technology can enable the conductive layer to be more stable and has stronger stripping resistance. And the LED calculation can be matched to various structural designs of the support.
A step S20 of jetting molten solder to the position of the soldering gap, comprising:
step S210, spraying molten solder to the welding gap between the welding plate and the conductive layer.
Wherein, support piece surface is provided with the conducting layer, and the charging connector includes the conducting layer, that is to say, the both sides in welding gap position are welded plate and conducting layer, realizes welded connection between welded plate and the conducting layer through the mode of spraying molten state soldering tin from this.
Referring to fig. 4, in addition to any of the first to third embodiments of the present invention, a fourth embodiment is provided, in which a step S20 of jetting molten solder to a solder gap position includes:
step S220, controlling the tin spraying equipment to spray molten tin at the welding gap position.
The tin spraying device comprises a laser tin spraying welding device, single-particle tin balls are conveyed to a designated spraying point in a mechanical movement mode, the tin balls are melted by laser, and the molten tin is sprayed to a designated position of a welding gap through a certain air pressure. Because the tin spraying technology adopted by the tin spraying equipment has the advantages of non-contact, small heat and controllable welding point position, the welding operation can be performed at the narrow welding gap position formed by the welding plate and the charging connector.
Referring to fig. 5 and 6, the present invention further provides a soldering apparatus for a charging head, where the charging head includes a charging connector 20 and a soldering board 10, and the charging connector 20 includes a conductive metal material, and charging or signal transmission to a corresponding electronic product is implemented through the conductive metal.

For example, the charging connector 20 is fixed by a fixing device, and a welding worker directly moves the welding plate 10 or moves the welding plate 10 toward the charging connector 20 by a moving device, and starts a welding operation. At a certain distance between the welding plate 10 and the charging connector 20, the positions of the welding plate 10 and the charging connector 20 are fixed, so that accuracy deviation can not occur during welding, and at the moment, the distance between the welding plate 10 and the charging connector 20 can effectively ensure that the welding tin 31 connects the welding plate 10 and the charging connector 20 together. The welding distance between the welding plate 10 and the charging connector 20 can be adjusted according to the design and use requirements. For example, the width of the welding gap is between 0.05mm and 0.2mm, and when the width of the welding gap is 0.05mm, the positions of the charging connector 20 and the welding plate 10 are more compact, so that the soldering tin can be effectively ensured to be welded and connected with the charging connector 20 and the welding plate 10. When the width of the welding gap is 0.2mm, the soldering tin is easy to spray, in other words, enough space is available for carrying out the tin spraying operation, and the smooth carrying out of the tin spraying operation is ensured. The width of the welding gap can be 0.1mm, so that the welding connection between the welding plate 10 and the charging connector 20 can be ensured, and enough operation space can be provided for tin spraying operation.
The soldering module 200 is used to spray the molten solder 31 at the soldering gap position. In the related art, the solder 31 is generally soldered to the soldering board 10 in advance, and then soldered by melting the solder 31.

Therefore, the process of hot-melting the soldering tin 31 on the soldering board 10 in the conventional soldering mode is reduced, and the soldering efficiency is effectively improved due to simple operation steps in the process of hot-melting the soldering tin 31 again when the charging connector 20 is arranged for soldering.
In the technical scheme of the embodiment, the molten solder 31 is sprayed at the welding gap position of the welding plate 10 and the charging connector 20, so that the process of repeatedly welding and re-melting the solder 31 in the prior art is avoided, the welding operation can be completed by once hot melting to spray the solder 31, the operation steps are effectively reduced, and the welding efficiency is improved.
