Description

Technical Field

[0001] The invention relates to the technical field of heat treatment of soft magnetic materials, and in particular to a heat treatment system of soft magnetic materials of an electromagnetic shielding sheet. Background Art

[0002] Under the background of rapid development of modern electronic technology, electromagnetic shielding technology is of vital importance to ensure the normal operation and stable performance of electronic equipment. As a key component to achieve electromagnetic shielding, the performance of electromagnetic shielding sheet directly affects the anti-interference ability and signal transmission quality of electronic equipment. As the core component of electromagnetic shielding sheet, the performance of soft magnetic material is determined by the heat treatment process and treatment system.

[0003] Traditional heat treatment systems for soft magnetic materials have many shortcomings in practical applications and are difficult to meet the increasingly demanding performance requirements of electronic equipment. During the heat treatment process, heating uniformity is one of the key factors affecting the performance of soft magnetic materials. However, existing systems are often unable to effectively heat all parts of the coil evenly, resulting in poor performance consistency of soft magnetic materials and affecting the overall shielding effect of electromagnetic shielding sheets. In some traditional heat treatment equipment, the position of the coil in the furnace is relatively fixed, and heating can only be achieved through overall temperature control in the furnace. This can easily cause large differences in heating in different parts of the coil, causing deviations in the magnetic properties of soft magnetic materials in different areas, reducing the reliability of electromagnetic shielding sheets in practical applications.

[0004] In order to improve the quality and efficiency of heat treatment of soft magnetic materials for electromagnetic shielding sheets, enhance the performance of soft magnetic materials, and meet the needs of the continuous development of electronic equipment, it is of great practical significance and urgent market demand to develop a heat treatment system for soft magnetic materials for electromagnetic shielding sheets with reasonable design and compact structure, which can effectively improve the uniformity of heating and the efficiency of picking and placing, and ensure stable fixation of the coil and good transmission.

When taking and placing the coil 5, it is only necessary to rotate the storage bracket 301 to a position aligned with the take-in and place port, and then push the moving bar 304 toward the take-in and place port through the horizontal driving mechanism, so that the moving bar 304 and the support box 4 can be pushed out from the take-in and place port to the outside of the vacuum heat treatment furnace 1, thereby improving the take-in and place efficiency of the coil 5.

[0048] Example 2

[0049] Reference Figure 1-15 , the difference between this embodiment and embodiment 1 is that the horizontal driving mechanism includes a screw rod 308, a threaded sleeve 313 is installed on the outer side of the screw rod 308, the threaded sleeve 313 and the moving bar 304 are fixed to each other, and a bevel gear A309 is fixed to one end of the screw rod 308;

[0050] When the driving screw 308 rotates, it can drive the threaded sleeve 313 to move horizontally, and then drive the moving bar 304 to move horizontally. A vertical shaft 310 is installed on the storage bracket 301. A bevel gear B311 is fixed to the bottom end of the vertical shaft 310. The bevel gear A309 is meshed with the bevel gear B311. A polygonal sleeve 312 is fixed to the top end of the vertical shaft 310. When the driving vertical shaft 310 rotates, the driving screw 308 can be driven to rotate through the meshing of the bevel gear A309 and the bevel gear B311.

By controlling the extension of the hydraulic cylinder 314, the polygonal pin 316 can be driven to move downward, so that the polygonal pin 316 is inserted into the polygonal sleeve 312. Then, the second rotating motor 317 is turned on to drive the polygonal sleeve 312 to rotate through the engagement of the spur gear A315 and the spur gear B318, thereby driving the screw rod 308 to rotate.

[0052] Example 3

[0053] Reference Figure 1-15 The difference between this embodiment and embodiment 2 is that a fixed sleeve 2 is provided on the outside of the rotating support shaft 3, the rotating support shaft 3 passes through the fixed sleeve 2, and the fixed sleeve 2 is fixed to the inner wall of the bottom end of the vacuum heat treatment furnace 1, and a spur gear C201 is fixed on the outside of the fixed sleeve 2 near the top position, a plurality of upper sleeves 305 are rotatably installed on the bottom end of the storage bracket 301, and a plurality of lower sleeves 402 are rotatably installed on the top end of the support box 4, and the two ends of the coil 5 are respectively inserted into the upper sleeve 305 and the lower sleeve 402, a spur gear D306 is fixed on the outside of the upper sleeve 305, and a spur gear E307 is rotatably installed between adjacent spur gears D306, and the spur gear D306 and the spur gear E307 are meshed in sequence, and one of the spur gears D306 is meshed with the spur gear C201;

[0054] After the storage bracket 301 is retracted into the vacuum heat treatment furnace 1, the spur gear D306 closest to the spur gear C201 is meshed with the spur gear C201. Therefore, during the heat treatment process, when the first rotating motor 302 can drive the rotating support shaft 3 to rotate, and then drive the coil 5 to continuously change its position, the closest spur gear D306 will rotate, and then through the transmission of the spur gear E307, the multiple coils 5 can rotate synchronously, further improving the uniformity of heating and improving the efficiency and effect of heat treatment.

[0055] In order to facilitate the taking and placing of the coil 5 and improve the stability of the installation of the coil 5, a top rod 401 is vertically and movably installed at the top of the support box 4, and the top of the top rod 401 is rotatably connected to the lower sleeve 402, and the bottom end of the top rod 401 extends to the inside of the support box 4 and is fixed with a horizontal bar 403, and a groove is provided at the bottom end of the horizontal bar 403, and a horizontal shaft 404 is rotatably installed in the support box 4, and a cam 408 is fixed to the outside of the horizontal shaft 404, and the top of the cam 408 extends into the groove, and one end of the cam 408 extends to the outside of the support box 4 and is fixed with a transmission rod 405, and a torsion spring 407 is installed on the outside of the horizontal shaft 404, and a spiral guide groove 406 is provided on the outside of the transmission rod 405, and a guide rod 203 is fixed to the outside of the fixed sleeve 2 near the bottom end through the horizontal rod 202, and the guide rod 203 is an "L"-shaped structure, and the bent end of the guide rod 203 is inserted into the spiral guide groove 406;

[0056] When the storage bracket 301 is retracted into the vacuum heat treatment furnace 1, the transmission rod 405 moves toward the cross bar 202, and the guide rod 203 is inserted into the spiral guide groove 406. When the storage bracket 301 continues to move, the guide rod 203 moves along the spiral guide groove 406, thereby driving the transmission rod 405 to rotate, and then driving the horizontal shaft 404 to rotate. When the storage bracket 301 is completely retracted into the vacuum heat treatment furnace 1, the cam 408 just pushes the lower sleeve 402 to the highest point, thereby passing through the lower sleeve 402. 02 and the upper sleeve 305 clamp the coil 5. When the storage bracket 301 is moved out into the vacuum heat treatment furnace 1, the torsion spring 407 drives the cam 408 to rotate 180 degrees, so that the lower sleeve 402 moves to the lowest point. At this time, the upper sleeve 305 is separated from the top of the coil 5, so that the coil 5 can be easily removed or a new coil 5 can be installed. The storage bracket 301 is automatically clamped and fixed when it is retracted, and the coil 5 is automatically released when the storage bracket 301 is moved out.

The axial array distribution of the sleeve 305 is such that when the coil 5 is clamped and fixed, the clamped top end of the coil 5 will push the lifting plate 3054 upward, causing the rack 3056 to move upward, thereby driving the clamping member 3052 to move toward the top end of the coil 5 through the engagement of the rack 3056 with the spur gear F3053, automatically clamping the coil 5. The clamping member 3052 is an arc-shaped structure, and a vertical anti-skid ridge is provided on the side where the clamping members 3052 are close to each other.
