[0030] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.

[0031] Please refer to Figures 1 to 10 , a mobile phone spindle welding jig includes a base and a pressure plate assembly and a product placement platform arranged on the base; the product placement platform and the base are respectively provided with a first positioning pin and a first positioning hole that cooperates with the first positioning pin, and a positioning groove is provided on a side of the product placement platform close to the pressure plate assembly; the pressure plate assembly can be movable relative to the base to approach or move away from the positioning groove, and an operating window and an air supply channel are opened on the pressure plate assembly, one end of the air supply channel is connected to the operating window, and the other end of the air supply channel is connected to the side of the pressure plate assembly.

[0032] As can be seen from the above description, the beneficial effects of the present invention are: the mobile phone spindle welding jig is simple and convenient to use. When welding mobile phone spindle parts, the parts are first placed in the positioning slots of the product display platform. The pressure plate assembly then presses against the parts to be welded to prevent them from moving during the welding process. The working window is used to avoid the welding head so that the welding head can contact the welding part of the part. The gas supply channel is used to input inert gas into the working window to prevent the parts from oxidizing and blackening during welding.

[0033] Furthermore, a cylinder is provided on the base, and the cylinder is drivingly connected to the pressure plate assembly.

[0034] From the above description, it can be seen that providing a cylinder can reduce manpower consumption and improve work efficiency.

[0035] Furthermore, the product placement platform includes a carrier plate and a plurality of limit blocks detachably mounted on the carrier plate, and the positioning groove is formed between at least two of the limit blocks.

[0036] From the above description, it can be seen that the shape and size of the positioning groove can be changed by changing the shape and size of the limit block, so that the positioning groove can be suitable for different models of mobile phone spindle parts, which is beneficial to improve the applicability of the product placement platform and reduce equipment costs.

[0037] Furthermore, at least one plunger is provided on the product placement platform.

[0038] As can be seen from the above description, the plunger is used to abut against the part, thereby accurately limiting the position of the part.

[0039] Furthermore, the product placement platform is also provided with magnetic parts.

[0040] As can be seen from the above description, the magnetic member can absorb some parts to prevent the parts from accidentally exiting the positioning groove.

[0041] Furthermore, the pressure plate assembly includes an upper base plate, a floating pressure plate and an elastic member. The floating pressure plate is arranged on the side of the upper base plate close to the product placement platform. The operating window is opened on the floating pressure plate. The elastic member is arranged between the upper base plate and the floating pressure plate. The elastic member is used to drive the floating pressure plate to move toward the direction close to the product placement platform.

[0042] As can be seen from the above description, a floating pressure plate of corresponding shape can be selected according to the shape of the product to be welded. The elastic member can make the floating pressure plate press tightly against the part during welding, thereby preventing the part from moving accidentally.

[0043] Furthermore, the floating pressure plate and / or the upper base plate are respectively provided with limiting pits, and the ends of the elastic members are arranged in the limiting pits.

[0044] It can be seen from the above description that the limiting pit is used to limit the position of the elastic member and prevent the elastic member from being damaged due to excessive pressure.

[0045] Furthermore, the gas supply channel includes a first gas supply hole opened on the upper base plate and a second gas supply hole opened on the floating pressure plate, the two ends of the first gas supply hole are respectively connected to the side of the upper base plate and the side of the upper base plate close to the floating pressure plate, and the two ends of the second gas supply hole are respectively connected to the side of the floating pressure plate close to the upper base plate and the working window.

[0046] As can be seen from the above description, splitting the gas channel into a first gas hole and a second gas hole allows the opening connecting the gas channel to the external gas supply to be located on the side of the upper base plate, thereby reducing the overall thickness of the floating pressure plate and lowering equipment costs. When the mobile phone spindle welding jig is in operation, the first gas hole and the second gas hole are connected to form the gas channel.

[0047] Furthermore, the pressure plate assembly and the product placement platform are respectively provided with a second positioning pin and a second positioning hole that cooperates with the second positioning pin.

[0048] From the above description, it can be seen that the second positioning pin and the second positioning hole can limit the relative position of the pressure plate assembly and the product placement platform, so that the pressure plate assembly can accurately press on the product parts to avoid damaging the product parts.

[0049] Furthermore, a gas pipe quick connector connected to the gas transmission channel is provided on the side of the pressure plate assembly.

[0050] As can be seen from the above description, the gas pipe quick connector can facilitate the connection between the gas transmission channel and the external gas supply equipment.
