[0010] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0011] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0012] like Figure 1 , Figure 2 As shown, the syringe-type automatic welding head includes a welding fixed cylinder 11, a motor buckle 1 is arranged inside the welding fixed cylinder 11, and a numerical control motor 2 is connected inside the motor buckle 1, so that the motor buckle 1 and the numerical control motor 2 constitute the numerical control motor area of ​​the present invention. The output shaft of the numerical control motor 2 is connected to the gear shaft 4 through the bevel gear steering mechanism 3, and the gear shaft 4 is connected to the crank piston mechanism. The piston 7 in the crank piston mechanism constitutes the crank piston propulsion area, and the gear shaft 4 connects the numerical control motor area with the crank piston propulsion area. The other end of the piston 7 extends into the main pipeline of the electric soldering iron 9, and a tin inlet 8 is arranged on the upper part of the electric soldering iron 9, and the outlet of the tin inlet 8 is connected to the main pipeline of the electric soldering iron. An epitaxial needle 10 is arranged at the end of the electric soldering iron 9. Thus, the tin inlet 8, the electric soldering iron 9 and the epitaxial needle 10 constitute the soldering iron tin melting area.

[0013] Further, the crank piston mechanism means that the gear shaft 4 is arranged at one end of the first crank 5, the other end of the first crank 5 is hinged to the second crank 6, and the other end of the second crank 6 is hinged to one end of the piston 7. In this way, the crank piston propulsion area is composed of a group of crank piston mechanisms, and the piston 7 performs intermittent linear motion to push the tin liquid column inside the main pipe of the electric soldering iron 9.

[0014] Furthermore, the temperature of the soldering iron 9 is maintained above 600 degrees, and the tin wire in the tin inlet is quickly melted into liquid and enters the main pipeline of the soldering iron 9. The tin liquid column inside the main pipeline of the soldering iron 9 is pushed by the piston 7 to form tin droplets at the end of the epitaxial needle 10, and the stripped wire is connected to complete the welding at the interface of the semiconductor refrigeration plate.

[0015] Furthermore, the epitaxial needle 10 is detachably connected to the end of the electric soldering iron 9 by means of a snap or thread connection, so that epitaxial needles of different lengths can be easily replaced to meet different welding requirements.

[0016] The present invention provides a syringe-type automatic welding head, and its working principle is as follows: it mainly includes a numerical control motor area, a crank piston propulsion area, and a soldering iron tin melting area. Power is generated by the numerical control motor area, and steering is performed through a bevel gear steering mechanism 3, and a first crank 5 is connected through a gear shaft 4, and then a second crank 6 is connected. In this way, the crank piston mechanism transmits power, and the piston 7 continuously propels the tin liquid column in the electric soldering iron 9 to form tin droplets. The epitaxial needle 10 is detachable, and epitaxial needles of different lengths can be replaced to meet different welding requirements.

[0017] The syringe-type automatic welding head of the present invention is suitable for welding in narrow gaps, which can greatly improve welding efficiency, reduce production costs, and increase production output. Due to the special shape of semiconductor refrigeration plates, traditional manual welding methods are currently used in production, and workers are prone to problems such as fatigue and misoperation, and the welding quality is determined by the technical ability of the operator, and it is impossible to generate a unified standard. The automation technology used in the present invention can accurately control the welding parameters, ensure the consistency of welding quality, and improve the quality and service life of the refrigeration plate.

[0018] In summary, the syringe-type automatic welding head is a very important tool in the production of semiconductor refrigeration chips. It can improve production efficiency, improve the stability of welding quality, and has many advantages.

[0019] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several changes and improvements can be made without departing from the overall concept of the present invention, which should also be regarded as the scope of protection of the present invention.
