Description

Technical Field

[0001] The invention relates to the field of electronic device demagnetization equipment, in particular to a demagnetization processing device for electronic communication equipment. Background Art

[0002] In today's era of rapid development of electronic communication technology, electronic communication equipment is widely used in various fields, such as smart phones, tablet computers, communication base station equipment, etc. However, these devices may be magnetized to varying degrees during the manufacturing process, after long-term use, or when affected by an external strong magnetic field environment.

[0003] Once electronic communication equipment is magnetized, it will cause many serious problems. For example, in terms of signal transmission, magnetization may cause signal distortion, attenuation or even interruption, greatly reducing the quality and stability of communication. For communication base station equipment and smart phones that have extremely high requirements for signal accuracy, this will seriously affect the user's communication experience, such as frequent call interruptions and network delays. In terms of equipment performance, magnetization will cause the working parameters of electronic components to shift, resulting in adverse consequences such as equipment heating, increased energy consumption, and shortened service life, increasing equipment maintenance costs and replacement frequency, and placing a heavy economic burden on companies and industries that use electronic communication equipment on a large scale.

[0004] There are many shortcomings in the existing demagnetization technologies and equipment on the market. Some traditional demagnetization methods, such as simple heating demagnetization, are difficult to accurately control the degree of demagnetization, and may cause thermal damage to the precision components of electronic equipment, affecting the overall performance and reliability of the equipment. Although some demagnetization devices can eliminate magnetism to a certain extent, they often have problems such as incomplete demagnetization, complicated operation, and low efficiency. For example, some demagnetization equipment can only demagnetize local areas of the equipment and cannot achieve a full-range and uniform demagnetization effect, resulting in some residual magnetism inside the equipment, which cannot meet the needs of modern electronic communication equipment for high-precision demagnetization. In addition, the existing demagnetization equipment lacks good adaptability and versatility when demagnetizing electronic communication equipment of different shapes and sizes, and often requires cumbersome adjustments and modifications for specific equipment, which increases the cost of use and the difficulty of operation.

[0022] In this embodiment, rack plates 12 are fixedly connected at the staggered positions of the inner ends of the movable blocks 8, a transmission gear 13 is movably installed in the middle of the movable groove 7 through a bearing seat, and the two sides of the transmission gear 13 are respectively meshed and connected with the two rack plates 12.

The telescopic cylinder 14, as a power source, can quickly and forcefully push the movable block 8 to move, thereby starting the entire clamping and fixing operation process.

[0023] Specifically, the electronic device to be demagnetized is carefully placed inside the outer cover 32, and then the telescopic cylinder 14 is started. The telescopic cylinder 14 will quickly push the movable block 8 on one side to move precisely inward along the movable groove 7. While the movable block 8 moves, it will drive the rack plate 12 fixed on its inner end to follow the movement, and the rack plate 12 will precisely mesh with the transmission gear 13. Due to the special structure and position of the transmission gear 13, it can drive the rack plate 12 and the movable block 8 on the other side to move inward synchronously, thereby realizing the simultaneous and smooth movement of the two movable blocks 8 inward. Through this coordinated movement of the two movable blocks 8, the transmission rod 9, the fixed seat 6, the mounting frame 10 and the clamping cylinder 11 on both sides can be driven to move precisely inward at the same time, and then the clamping cylinder 11 can be used to clamp and fix the electronic device.

[0024] Furthermore, a driving bevel gear 15 is fixedly installed on the middle outer diameter of the transmission rod 9, and a driven bevel gear 17 is fixedly connected to the outer end of the short shaft 16, and the bottom end of the driven bevel gear 17 is meshed and connected with one end of the corresponding side driving bevel gear 15. This bevel gear transmission structure can effectively change the transmission direction and speed, realize the rotation movement of the clamping cylinder 11, thereby driving the electronic equipment to rotate continuously to meet the all-round needs during the demagnetization process.

[0025] Furthermore, outer rods 18 are movably installed on both sides of the top of the base 1, and inner rods 19 are movably installed inside the outer rods 18. Key slots 21 are provided on both sides of the inner part of the outer rod 18. Splines 20 are fixedly connected at both ends of the inner rod 19, and the outer ends of the splines 20 are movably arranged inside the corresponding side key slots 21. The matching structure of the key slots and the splines can not only ensure the stable rotation of the inner rod 19 in the outer rod 18, but also realize the effective transmission of power. Universal shafts 22 are movably installed on the top of the inner rod 19, and the bottom ends of the transmission rods 9 extend to the bottom of the table 3 and are movably arranged at the ends of the universal shafts 22 on the corresponding sides. The setting of the universal shafts 22 makes the transmission more flexible, which can adapt to the power transmission requirements at different angles and ensure the smooth operation of the entire transmission system.

[0026] Specifically, after the clamping and fixing is completed, the stepper motor 23 is started, and the stepper motor 23 drives the long shaft 24 to rotate stably. When the long shaft 24 rotates, it will drive the first worm gears 26 on both sides thereof to rotate synchronously, and the first worm gear 26 will mesh with the first worm wheel 25 on the outer rod 18 for transmission, thereby driving the first worm wheel 25 and the outer rod 18 to rotate accurately, and by utilizing the limiting cooperation between the keyway 21 in the outer rod 18 and the spline 20 on the outer side of the inner rod 19, the inner rod 19 will follow the outer rod 18 to rotate stably, and the rotating inner rod 19 will drive the universal joint 22 to rotate flexibly, thereby driving the two transmission rods 9 to rotate at the same time, and when the transmission rod 9 rotates, it will drive the active bevel gear 15 on its outer diameter to rotate synchronously, and through the precise meshing transmission of the active bevel gear 15 and the driven bevel gear 17, the short shaft 16 and the clamping cylinder 11 can be driven to rotate, thereby driving the electronic equipment to rotate continuously, so as to achieve an all-round demagnetization effect.

[0027] Furthermore, a stepper motor 23 is movably mounted on one side of the base 1, a long shaft 24 is fixedly mounted on the driving end of the stepper motor 23, a first worm gear 25 is fixedly mounted on the outer diameter of the outer rod 18, a first worm 26 is fixedly mounted on the outer diameters of both sides of the long shaft 24, and the inner side of the first worm 26 is meshed and connected with one end of the first worm gear 25 on the corresponding side. The stepper motor 23, as one of the main power sources in the device, can accurately control the rotation of the outer rod 18 through the transmission mode of the worm gear, thereby driving the movement of a series of components, realizing the rotation of the electronic device and the generation and change of the magnetic field.

[0028] Furthermore, a straight rod 27 is movably installed in the middle of the top of the base 1, a second worm gear 28 is fixedly installed on the lower outer diameter of the straight rod 27, a second worm 29 is fixedly installed on the middle outer diameter of the long shaft 24, and the second worm 29 is meshingly connected with the inner end of the second worm gear 28, the top of the straight rod 27 extends to the top of the table 3 and is fixedly connected to a rotating disk 30, and electromagnets 31 are fixedly installed on both sides of the top of the rotating disk 30. This worm gear transmission structure is also used to drive the rotating disk 30 and the electromagnet 31, so that the electromagnet 31 can make a circular motion with the rotation of the long shaft 24, generate an interactive magnetic field, and effectively disrupt and rearrange the internal magnetic domains of the electronic equipment, thereby realizing the function of preliminary demagnetization.

[0029] Specifically, when the long shaft 24 rotates, it will also drive the second worm 29 in the middle to rotate, and the second worm 29 will mesh with the second worm wheel 28 on the straight rod 27 to drive the second worm wheel 28 and the straight rod 27 to rotate, thereby driving the second worm wheel 28 and the straight rod 27 to rotate, and then driving the rotating disk 30 to rotate stably. When the rotating disk 30 rotates, it will drive the two electromagnets 31 on the top to make circular motion. When the electromagnets 31 are turned on, the two electromagnets 31 will generate an interactive magnetic field, and the interactive magnetic field will rotate continuously with the movement of the electromagnets 31. This rotating magnetic field can effectively disrupt and rearrange the basic arrangement of the internal magnetic domains of the electronic device, thereby achieving preliminary demagnetization and improving the subsequent demagnetization quality.

[0030] Furthermore, a light rod 36 is movably installed inside the outer cover 32 at a position above the guide rod 33, and a bidirectional spiral groove 37 is opened on the middle outer diameter of the light rod 36. A round head pin 38 is fixedly installed on the top of the slide 34, and the end of the round head pin 38 is movably arranged inside the bidirectional spiral groove 37. When the light rod 36 rotates, the bidirectional spiral groove 37 will drive the round head pin 38 to move. Due to the limiting effect of the guide rod 33 on the slide 34, the slide 34 can only reciprocate left and right along the direction of the guide rod 33, thereby realizing the left and right movement of the pulse demagnetizer 35, so that it can apply a full-range pulse magnetic field to the rotating electronic equipment, thereby enhancing the demagnetization effect.

[0031] Furthermore, a driving wheel 39 is fixedly installed at the end of the long shaft 24, one end of the light rod 36 extends to the outside of the outer cover 32 and is fixedly installed with a driven wheel 40, and the outer diameters of the driving wheel 39 and the driven wheel 40 are connected by a synchronous belt 41. Through this synchronous belt transmission method, the rotation of the long shaft 24 can be accurately transmitted to the light rod 36, driving the light rod 36 to rotate, realizing the coordinated work of the left and right movement of the pulse demagnetizer 35 and the movement of other components, further improving the overall performance and demagnetization effect of the device.

[0032] Specifically, the rotating long shaft 24 will drive the driving wheel 39 to rotate, and the transmission effect of the synchronous belt 41 can accurately drive the driven wheel 40 and the light rod 36 to rotate. When the light rod 36 rotates, it will drive the bidirectional spiral groove 37 in the middle to rotate. Since the bidirectional spiral groove 37 is composed of two spiral grooves with opposite spiral directions but connected end to end, when it rotates, it will drive the round head pin 38 to slide accurately inside. By using the limiting effect of the guide rod 33 on the slide 34, the slide 34 can be made to reciprocate left and right along the direction of the guide rod 33, thereby driving the pulse demagnetizer 35 to move left and right. At this time, the pulse demagnetizer 35 is turned on to apply a pulse magnetic field to the electronic equipment, so as to give a stronger impact on the stubborn magnetic domains to rearrange them, and cooperate with the continuously rotating electronic equipment to achieve a better demagnetization effect.

[0033] Working principle: First, place the electronic device to be demagnetized inside the outer cover 32, and then start the telescopic cylinder 14. The telescopic cylinder 14 will quickly push the movable block 8 on one side to move inward along the movable groove 7. While the movable block 8 moves, it will drive the rack plate 12 fixed on its inner end to move along, and the rack plate 12 will mesh with the transmission gear 13 for transmission. Due to the special structure and position of the transmission gear 13, it can drive the rack plate 12 and the movable block 8 on the other side to move inward synchronously, thereby realizing the simultaneous and smooth inward movement of the two movable blocks 8. Through this coordinated movement of the two movable blocks 8, the transmission rods 9, the fixed seat 6, the mounting frame 10 and the clamping cylinder 11 on both sides can be driven to move inward at the same time, and then the clamping cylinder 11 can be used to implement The clamping and fixing work of the electronic device is now carried out. The clamping force and position can be flexibly adjusted according to the specific shape and size of the electronic device to ensure that the electronic device always maintains a stable position during the subsequent demagnetization process, which is convenient for subsequent efficient demagnetization work. After completing the clamping and fixing, the stepper motor 23 is started. The stepper motor 23 will drive the long shaft 24 to rotate. When the long shaft 24 rotates, it will drive the first worm 26 on both sides thereof to rotate synchronously. The first worm 26 will mesh with the first worm wheel 25 on the outer rod 18, thereby driving the first worm wheel 25 and the outer rod 18 to rotate. By utilizing the limited cooperation between the keyway 21 in the outer rod 18 and the spline 20 on the outer side of the inner rod 19, the inner rod 19 will rotate with the outer rod 18, and the rotating inner rod 19 will drive the outer rod 18 to rotate. The long shaft 24 rotates along the axis 22, thereby driving the two transmission rods 9 to rotate at the same time. When the transmission rod 9 rotates, the active bevel gear 15 on its outer diameter will be driven to rotate synchronously. Through the meshing transmission of the active bevel gear 15 and the driven bevel gear 17, the short shaft 16 and the clamping cylinder 11 can be driven to rotate, thereby driving the electronic equipment to rotate continuously to achieve a full range of demagnetization effects. At the same time, when the long shaft 24 rotates, it will also drive the second worm 29 in the middle to rotate. The second worm 29 will mesh with the second worm wheel 28 on the straight rod 27, thereby driving the second worm wheel 28 and the straight rod 27 to rotate, and then drive the rotating disk 30 to rotate stably. When the rotating disk 30 rotates, it will drive the two electromagnets 31 on the top to do circular motion. When the electromagnet is turned on, When the electromagnets 31 rotate, the two electromagnets 31 will generate an alternating magnetic field, and the alternating magnetic field will rotate continuously with the movement of the electromagnets 31. This rotating magnetic field can effectively disrupt and rearrange the basic arrangement of the internal magnetic domains of the electronic device, thereby achieving preliminary demagnetization and improving the quality of subsequent demagnetization. At the same time, the rotating long shaft 24 will drive the driving wheel 39 to rotate, and the transmission effect of the synchronous belt 41 can accurately drive the driven wheel 40 and the light rod 36 to rotate. When the light rod 36 rotates, it will drive the bidirectional spiral groove 37 in the middle to rotate. Since the bidirectional spiral groove 37 is composed of two spiral grooves with opposite spiral directions but connected end to end, when it rotates, it will drive the round head pin 38 to slide inside, and the guide rod 33 will limit the slide 34.The slide 34 can be reciprocated left and right along the direction of the guide rod 33, thereby driving the pulse demagnetizer 35 to move left and right. At this time, the pulse demagnetizer 35 is turned on to apply a pulse magnetic field to the electronic device, which has a stronger impact on the stubborn magnetic domains to rearrange them. In combination with the continuously rotating electronic device, a better demagnetization effect is achieved. After the demagnetization is completed, the clamping cylinder 11 is controlled to loosen and move outward synchronously, and the electronic device can be safely taken out.
