As shown in fig. 1, a full-automatic expanding type dip welding machine includes a feeding mechanism 20, a translation mechanical arm 30, a turnover mechanism 40, a clamping and carrying mechanism 50, a tin-dipping mechanism 60 and a welding mechanism 70, which are arranged on a box 10, wherein after a stator 80 is conveyed to a predetermined position on the feeding mechanism 20, the translation mechanical arm 30 clamps and places the stator on the turnover mechanism 40, the turnover mechanism 40 drives the stator to turn over to a state that a terminal 81 is upward, and after the stator is clamped and placed at the tin-dipping mechanism 60 by the clamping and carrying mechanism 50 and dips the terminal 81, the stator continues to move to the welding mechanism 70 to complete welding. The specific structure and working process are as follows.

As shown in fig. 2, the feeding mechanism 20 includes a conveyor belt 21 for conveying the stator 80, a first position detection sensor 23 and an adsorption cylinder 24, the first position detection sensor 23 is disposed at a predetermined position downstream of the stator 80 in the moving direction, and the first position detection sensor 23 is electrically connected to a motor for driving the conveyor belt 21; the adsorption cylinder 24 is arranged at the downstream of the conveying direction of the conveying belt 21, the moving direction of the piston rod is consistent with the moving direction of the conveying belt 21, the adsorption cylinder 24 is fixedly connected with the adsorption magnetic steel 26 through the adsorption fixing frame 25, and the adsorption magnetic steel 26 transfers the stator 80 to the downstream position of the original preset position. The stator 80 is placed at the upstream of the conveyor belt 21 and moves to a preset position along with the conveyor belt 21, the first position sensor 23 adopts a correlation type photoelectric sensor, when the first position sensor detects that the stator 80 reaches the preset position, a signal is transmitted to stop the conveyor belt 21 to fix the position of the stator 80, then the adsorption air cylinder 24 drives the adsorption magnetic steel 26 to be close to the stator 80 and adsorb the stator 80 away from the original position, a distance is drawn between the stator 80 and other stators 80 on the conveyor belt 21, and the translation mechanical arm 30 is convenient to clamp the stator 80. Preferably, in order to limit the moving track and position of the stator 80 and ensure the clamping effect, the two sides of the moving track of the stator 80 are fixedly provided with limit stop rods 22, the limit stop rods 22 are fixedly connected to a fixing frame of the feeding mechanism 20, and a conveyor belt front baffle 27 is fixedly arranged at the downstream of the fixing frame and used for limiting in the moving process of the stator 80. The quantity of adsorbing magnet steel 26 is 2 or more, and parallel arrangement in the horizontal plane, the angle and the position of stator 80 when restricting adsorbing stator 80. After the adsorption magnetic steel 26 is attached to the stator 80, a gap exists between the surface of the stator 80 and the adsorption fixing frame 25, so that a space is provided for the clamping jaw of the translation mechanical arm 30.

As shown in fig. 3, the translation mechanical arm 30 is slidably disposed on the first translation module 31, the end of the translation mechanical arm 30 is disposed with a translation clamping cylinder 32 capable of rotating in a horizontal plane, and the translation clamping cylinder 32 can be a finger cylinder, and is used for clamping and transporting the stator 80 adsorbed by the adsorption magnetic steel 26 to the turnover mechanism 40. Depending on the relative position between the feeding mechanism 20 and the turnover mechanism 40, the translation robot arm 30 needs to rotate the stator 80 in the horizontal plane and then place the stator at the turnover mechanism 40.

Since the ends of the terminals 81 of the stator 80 protrude from the end surface of the stator 80, in order to smoothly convey the stator 80, the stator 80 is placed on the conveyor belt 21 in such a manner that the terminals 81 are kept upward, but the terminals 81 need to be placed downward when being dipped in tin, and therefore the stator 80 needs to be turned over at the turning mechanism 40. The structure of the turnover mechanism 40 is shown in fig. 4, and includes a rotary cylinder 41, a rotary shaft 42 and a turnover clamping cylinder 44, the rotary shaft 42 is driven by the rotary cylinder 41 and rotates around its axis in the horizontal plane, the rotary clamping cylinder 44 is fixedly connected to two ends of the rotary shaft 42 through a rotary shaft connecting block 43, and openings of the two rotary clamping cylinders 44 are arranged oppositely.

Preferably, the rotary clamping cylinders 44 are 2 groups, each group is 2 and is respectively arranged at two ends of the rotating shaft 42, and the 2 groups of rotary clamping cylinders 44 are arranged in central symmetry about the rotating shaft, so that 2 turning stations are formed, and the 2 groups of rotary clamping cylinders 44 can be used simultaneously to improve the processing efficiency.

The inverted stator 80 is taken and placed to the tin immersion mechanism 60 by the clamping and carrying mechanism 50, and the clamping and carrying mechanism 50 keeps a clamping state and a clamping position unchanged in the process of tin immersion of the terminal 81. As shown in fig. 7 and 8, the wicking mechanism 60 includes a flux box 61 and a lifting cylinder 62 fixedly disposed on the frame 10, the flux box 61 contains flux, the lifting cylinder 62 drives the lifting plate 63 to reciprocate above the flux box 61, one side of the lifting plate 63 close to the flux box 61 is fixedly connected with a bushing 65 through a connecting plate 64, the bushing 65 is disposed in the flux box 61 and is disposed corresponding to the number and position of the terminals 81, and the number and position of the flux box 61 and the bushing 65 are adjusted according to the number and position of the terminals 81. The sleeve 65 is driven by the lifting cylinder 62 to lift up and down in a reciprocating mode, the sleeve 65 sinks below the liquid level of the soldering flux in the soldering flux box 61 when descending, the soldering flux is contained in the hollow cavity when ascending, the sleeve 65 ascends until the terminal 81 is immersed in the soldering flux in the hollow cavity, and then the sleeve 65 descends to be separated from the terminal 81, so that the terminal 81 is immersed in tin. The structure replaces the prior tin immersion method of immersing the whole stator 80 downwards, so that the flux consumption required in the flux box 61 is reduced, and the flux can be coated on the surface of the terminal 81 more uniformly. Then the stator 80 is driven by the clamping and carrying mechanism 50 to complete welding at the position of the welding mechanism 70, and wave soldering is preferably adopted in the scheme.

The welded stator 80 is driven by the clamping and carrying mechanism 50 to be placed back to the vacant station of the turnover mechanism 40, and is transferred to the next process by the translation mechanical arm 30 without using other equipment. Preferably, in order to further save the equipment cost and the occupied space of the equipment, the turnover mechanism 40, the clamping and carrying mechanism 50, the dip-soldering mechanism 60 and the welding mechanism 70 are respectively 2 or more sets, and are arranged in parallel along the extending direction of the first translation module 31, so that 2 or more sets of dip-soldering equipment are fed by one set of the feeding mechanism 20 and the translation mechanical arm 30.
