Description

Technical Field

[0001] The invention relates to the technical field of automatic soldering machines, in particular to an automatic soldering machine for insulators of metal shells. Background Art

[0002] With the rapid development of integrated circuit technology in recent years, the process has gradually matured, and the metal-ceramic insulator package shell has been used more and more, occupying a place in the packaging field. Although there are many types of this shell, its structure is basically the same, generally consisting of a base, a frame, a ceramic insulator, a lead and solder, and a brazing machine is generally required for assembly.

[0003] At present, the brazing machine in the prior art is generally a high-temperature brazing furnace. When in use, the furnace body is opened, and then the ceramic insulators and metal parts to be brazed are coated with solder and placed inside the furnace body, and then the furnace body is closed for brazing. When the brazing is completed, due to the high temperature inside the furnace body, burns are easily caused during the picking process, which poses a great safety hazard. Moreover, after the furnace body is opened, hot air scatters and causes waste, and the clamping and welding processes cannot be carried out at the same time, resulting in slow production speed. At the same time, during the welding process, the positions of the ceramic insulators and metal parts are fixed, which makes the welding speed slow and the welding uniformity poor. Therefore, it is of great significance to study a new metal shell insulator automatic brazing machine to solve the above problems. Summary of the invention

At this time, the sealed space can be heated by the heating guide wire, and the vacuum is drawn by the exhaust component to realize the brazing operation between the metal shell and the insulator. After welding, the heat-insulating shell is reset upward by the electric push rod. At this time, the elastic force of the first spring drives the sealing plate to reset downward and press it on the upper annular plate, thereby sealing the heat-insulating shell and preventing heat leakage, which leads to the problem of slow subsequent preheating operation.

[0021] 2. The automatic brazing machine for insulators of the metal shell drives the first gear and the second gear through the motor, so that the annular bar drives the turntable to rotate, and the turntable drives the transmission component and the elastic component to move in a circle. When the first bevel tooth and the bevel tooth segment are transmitted, the elastic potential energy of the torsion spring is stored, and when the roller moves and is squeezed by the arc block, the roller drives the bracket to move upward, so that the first bevel tooth is separated from the bevel tooth segment, and the second bevel tooth is upwardly meshed with the third bevel tooth. At this time, the torsion force of the torsion spring drives the first bevel tooth and the rotating shaft to rotate, so that the rotating shaft drives the second bevel tooth and the third bevel tooth to transmit, and the connecting shaft drives the connecting disk and the template to rotate. The rotation of the template can drive the metal shell and the insulator to rotate, so as to maintain the uniform brazing operation of the insulator and the metal shell.

[0022] 3. The automatic brazing machine for insulators of the metal shell drives the first gear and the second gear to transmit through the motor, and the rotation of the turntable drives the steering assembly to move, so that relay feeding can be carried out, and when the first bevel gear moves and meshes with the bevel gear segment, the first bevel gear drives the torsion spring to store elastic potential energy, and when the roller moves to the arc block position, the roller is squeezed by the arc block to drive the bracket to move upward, so that the bracket drives the transmission assembly to move upward, so that the first bevel gear is separated from the bevel gear segment, and at this time, the second bevel gear and the third bevel gear are transmitted, and at this time, the brazing part to be brazed is located below the heat insulation shell, and at the same time, the electric push rod drives The heat-insulating shell moves downward, so that the sealing gasket fits on the turntable, and through continuous pressure, the first spring is deformed, and the sealing plate is pushed up by the sliding rod, so that the heat-insulating shell continues to move downward and covers the periphery of the template. At this time, the hot air stored in the heat-insulating shell can first preheat the metal shell and insulator, and there is no need to preheat for a period of time by the heat generated by the heating wire, thereby shortening the brazing time. In addition, the torsion force of the torsion spring drives the rotating shaft to rotate, and the rotating shaft drives the second bevel gear and the third bevel gear to transmit, so that the connecting shaft drives the template to rotate. At this time, uniform heating can be ensured, thereby improving the brazing efficiency and the brazing quality. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, the torsion force of the torsion spring 206b drives the rotating shaft 206a to rotate, and the rotating shaft 206a drives the second bevel gear 206e and the third bevel gear 207b to transmit, so that the connecting shaft 207a drives the template 207d to rotate, and at this time, uniform heating can be ensured, thereby improving the brazing efficiency and the brazing quality.

[0051] The working principle of the present invention is as follows: the fixing bolt 208a can be rotated in advance, so that the fixing bolt 208a pushes the movable plate 208c and the pulley 208d to move, so that the pulley 208d is attached to the roller 206d, and the degree of tightness between the pulley 208d and the roller 206d can be adjusted by the degree of tightening the fixing bolt 208a, so the rotation speed of the roller 206d can be adjusted, and then the metal shell and insulator to be brazed are placed in the inner cavity of the template 207d, and then the motor 204b is controlled to run, the motor 204b drives the first gear 204c and the second gear 204d to transmit, the second gear 204d drives the turntable 205 to rotate through the annular strip 204e, and the turntable 205 drives the steering assembly 2 07, the support rod 211 and the support bar 210 rotate to rotate the elastic component 203, when the first bevel tooth 206c meshes with the bevel tooth segment 209, the first bevel tooth 206c rotates and drives the torsion spring 206b to store elastic potential energy, and the roller 203b moves to the position of the arc block 202, the arc block 202 squeezes the bracket 203a to move upward, the bracket 203a drives the rotating shaft 206a to move upward, the first bevel tooth 206c and the second bevel tooth 206e move upward, the second bevel tooth 206e and the third bevel tooth 207b drive, and the template 207d is located below the heat insulation shell 103a, the electric push rod 101b can push the heat insulation shell 103a to move downward, the heat insulation shell 103a 3a drives the ceramic fiber sealing layer 104 to move downward, so that the sealing pad 105e contacts the turntable 205 downward, and by continuously applying pressure, the lower annular plate 105d drives the sliding rod 105b to move upward, and the sliding rod 105b drives the sealing plate 105a to move, so that the heat insulation shell 103a is located at the template 207d position. At this time, the heating guide wire 103b performs a heating operation, and the vacuum device 102a can extract the air inside the heat insulation shell 103a through the exhaust pipe 102b to make it a vacuum state. At this time, the brazing operation can be performed by heating. During the brazing process, the torsion of the torsion spring 206b is released to drive the rotating shaft 206a and the second bevel gear 206e to rotate, and the second bevel gear 206e The third bevel tooth 207b drives the connecting shaft 207a to rotate, and the connecting shaft 207a drives the connecting disk 207c to rotate, so that the template 207d rotates to keep the metal shell and the insulator evenly heated for brazing. After the brazing is completed, the electric push rod 101b retracts, so that the elastic potential energy of the first spring 105c drives the sealing plate 105a to reset downward, so that the sealing plate 105a is pressed on the upper annular plate 106 to keep the insulation shell 103a sealed, and at the same time, the internal hot air can be retained, so as to facilitate the subsequent heating brazing operation. Then the motor 204b continues to move to rotate the turntable 205, so that the insulator after brazing is exposed and then taken out.
