Description

Technical Field

[0001] This invention relates to the field of magnetic head housing production, and particularly to a welding apparatus for magnetic head housing production. Background Technology

[0002] A magnetic head consists of a magnetic core and a head shell. The head shell contains a grounding plate, which connects the magnetic core to the FPC grounding pad or the cable ground wire. Currently, manufacturers use welding to attach the grounding plate to the head shell during production. However, due to the limited internal space and obstructed view of the head shell, welders often struggle to accurately determine the welding position of the grounding plate. This can lead to incorrect welding parameters, inconsistent grounding plate positions within the same batch, or insufficient welding strength, posing a risk of detachment. All of these issues can severely impact head performance, causing incomplete or inaccurate data readings, or shortening the head's lifespan. Furthermore, if the grounding plate detaches from a semi-finished head shell, the process of re-welding it is even more complex.

[0003] To address this issue, a welding fixture for producing magnetic head housings, such as the one with patent number CN217493022U, was developed. However, this equipment has the following drawbacks in practical applications: when grounding plates need to be welded on both sides of the housing, the grounding plate on one side of the housing needs to be removed after welding, and the part of the housing that needs to be welded later is to be facing upwards. Then, the housing is placed on the welding head and the limiting block for fixation before the next welding work can be carried out. This increases the difficulty of the housing welding work and seriously affects its processing efficiency. Summary of the Invention

[0019] The top of the machine table 1 in the embodiment is provided with an L-shaped frame, and the L-shaped frame is provided with a driving mechanism for driving the upper electrode 10 to move up and down.

[0020] The feeding mechanism 7 includes a large circular groove 71 and a small circular groove 72 arranged on the top of the base 2, the axis lines of the large circular groove 71 and the small circular groove 72 are arranged in parallel with the installation inclined surface 6, the large circular groove 71 and the small circular groove 72 are arranged in communication, the top of the base 2 is provided with a feeding port 73 for communicating the small circular groove 72 with the upper guide groove 12, the inner bottom walls of the large circular groove 71 and the small circular groove 72 are inclined, and the inner bottom walls of the large circular groove 71, the small circular groove 72, the feeding port 73 and the upper guide groove 12 form a straight line, the top of the base 2 is further provided with a mounting frame 74 located above the small circular groove 72, the mounting frame 74 is provided with a motor II 75, the motor II 75 is provided with a vertical rod 76 extending into the small circular groove 72 and arranged coaxially with the small circular groove 72, and four groups of baffles 77 are arranged radially in the vertical rod 76.

[0021] As Figure 1 , 2The output shaft of the electric push rod 17 is provided with a fixing seat 16 for fixing the conductive block 14, the diameter of the conductive block 14 is smaller than the inner diameter of the vertical end opening of the H-shaped mounting channel 13, and a straight line is formed between the vertical ends of the conductive block 14 corresponding to the H-shaped mounting channel 13.

[0022] As shown in Figure 2 , 3 , the height between the upper and lower ends of the welding head II11 is equal to the spacing between the upper and lower groups of guide grooves 12, and the thickness of the horizontal end of the welding head II11 is smaller than the height of the horizontal end of the H-shaped mounting channel 13.

[0023] When in use, a plurality of grounding sheets are laid in the large circular groove 71, and the inclined rod 83 is rotated counterclockwise with the pivot 82 as the center, so that the metal ball 86 is separated from the left end of the strip-shaped seat 31, and then the magnetic head shell 4 is buckled on the left end of the strip-shaped seat 31 for fixation, and then the inclined rod 83 is loosened, and under the pulling force of the contraction of the spring 84, the inclined rod 83 is rotated clockwise, and finally the metal ball 86 on the mounting seat 85 is pressed against the left side of the shell 4, and at this time, the strip-shaped seat 31 and the metal ball 86 play a fixing role on the shell 4, preventing the shell 4 from sliding off the left end of the strip-shaped seat 31, and when the motor I32 drives the strip-shaped seat 31 to rotate with the shell 4, the left end surface of the shell 4 can rotate on the metal ball 86 and drive the metal ball 86 to rotate in the accommodating groove, so that the locking mechanism 8 can always lock and fix the shell 4 on the strip-shaped seat 31, and at the same time, it will not affect the rotation of the shell 4 to change the orientation.

[0024] As shown in Figure 4 , when the shell 4 is installed, the motor II75 rotates the baffle 77 through the vertical rod 76, so that the opening formed between the two groups of baffles 77 covers the communication opening between the large circular groove 71 and the small circular groove 72, and under the influence of the inclined arrangement of the inner bottom wall of the large circular groove 71, a group of grounding sheets inside will enter the small circular groove 72 through the communication opening between them and the small circular groove 72, and at this time, the motor II75 drives the vertical rod 76 to rotate the baffle 77, so that the two groups of baffles 77 drive the grounding sheets located between them to rotate in the small circular groove 72, while switching the orientation of the remaining baffles 77, so that the grounding sheets in the large circular groove 71 continuously enter the opening formed between any two adjacent groups of baffles 77, and when the grounding sheets driven by the baffle 77 in the small circular groove 72 move to the feeding port 73, they will flow into the upper guide groove 12, so as to intermittently feed the grounding sheets in the upper guide groove 12 at this time.

[0025] The ground sheet entering the upper guide groove 12 flows into the end of the guide groove 12 in the shell 4 along the bottom slope of the guide groove 12 at this time, or the ground sheet is smoothly slid in the guide groove 12 and flows into the shell 4 by artificial intervention, the depth of the guide groove 12 is greater than the thickness of the ground sheet, so that the ground sheet is facilitated to flow in the guide groove 12 and into the shell 4, and the problem that the thickness of the ground sheet matches the depth of the guide groove 12 to affect the subsequent flow into the shell 4 is prevented, and the welding head II 11 can slightly move downward in the H-shaped mounting channel 13 under the influence of its own gravity, so that the top end is retracted into the top opening in the H-shaped mounting channel 13, and the partial retraction in the H-shaped mounting channel 13 does not affect the flow of the ground sheet in the guide groove 12.

[0026] When the ground sheet flows to the designated position in the guide groove 12, the driving device drives the upper electrode 10 to move downward with the welding head I 9 and abuts against the top wall of the shell 4 above the ground sheet, the electric push rod 17 pushes the conductive block 14 into the bottom opening of the vertical end of the H-shaped mounting channel 13, and the welding head II 11 is slightly pushed upward in the H-shaped mounting channel 13, so that the top end of the welding head II 11 slides out of the top opening of the H-shaped mounting channel 13, and the top end pushes the ground sheet upward and closely abuts against the top wall in the shell 4, then the upper electrode 10 and the lower electrode 15 are respectively electrified, and the ground sheet and the head shell 4 are fused and integrated due to the high temperature generated between the welding head I 9 and the welding head II 11, so that the welding is completed.

[0027] After the welding of the ground sheet on the top wall in the shell 4 is completed, the conductive block 14 moves downward and resets, and the welding head I 9 moves upward and resets, then the motor I 32 drives the strip-shaped seat 31 and the shell 4 to rotate by 180 degrees, so that the inner wall of the shell 4 to be welded with the ground sheet is located above, and a straight line is formed between the upper guide groove 12 and the bottom walls in the large circular groove 71 and the small circular groove 72 at this time, so that the top wall in the shell 4 can be fed and welded by the foregoing steps, and the shell 4 is rotated to adjust the orientation by the positioning mechanism 3 and is intermittently fed in the shell 4 by the feeding mechanism 7, so that the welding work of the ground sheet on the upper and lower side walls in the shell 4 can be completed, the operation difficulty is reduced, and the work efficiency is improved.

[0028] The above detailed description of the present application is only a preferred embodiment of the present application, and cannot be considered as limiting the scope of the present application. Any equivalent changes and improvements made within the scope of the present application should still belong to the patent coverage of the present application.
