Description
Technical Field
[0001] This utility model relates to the field of magnetic material handling technology, specifically a weak magnetic pull-out type large-area planar iron picker. Background Technology
[0002] A small permalloy shielding shell made of thin strip is a precision component used for electromagnetic shielding, and is usually machined from permalloy thin strip.
[0003] Traditional magnetic pick-up devices use high-energy-product permanent magnets (such as neodymium iron boron) or electromagnets to transfer magnetic workpieces using a strong magnetic pull-type pick-up device. However, when transferring existing permalloy shielding shells after they have been neatly arranged and cleaned, the use of a strong magnetic pull-type pick-up device can cause deformation of the shielding shell, leading to additional losses during the product transfer process. To address these issues, the inventors have proposed a weak magnetic pull-type large-area planar magnetic pick-up device. Utility Model Content
[0004] To address the issue of deformation of the permalloy shielding shell caused by the transfer of the iron picker using a strong magnetic pull-out type, the purpose of this invention is to provide a weak magnetic pull-out type large-area planar iron picker.
[0005] To solve the above technical problems, this utility model adopts the following technical solution: a weak magnetic pull-out type large-area planar iron picker, including a support frame, an mounting plate slidably disposed between the support frames, a support frame disposed below the mounting plate, a first stainless steel plate slidably disposed within the support frame, a weak magnetic soft magnet fixedly disposed at the bottom end of the first stainless steel plate, a second stainless steel plate fixedly disposed on the bottom surface of the support frame, a frame fixedly disposed on the bottom surface of the second stainless steel plate, a soft magnetic layer placed within the frame, the soft magnetic layer being tightly attached to the bottom surface of the second stainless steel plate; a cylinder is mounted on the top surface of the mounting plate, a connecting plate is fixedly disposed at the output end of the cylinder, a traction rod is fixedly disposed on the bottom surface of the connecting plate, the traction rod is slidably inserted into the support frame, and the traction rod is fixedly disposed on the top surface of the first stainless steel plate. Firstly, when transfer is required, the device is moved below the permalloy shielding shell, and then, by turning on the motor, the rotating shaft is... The rotation drives the first bevel gear to rotate, which meshes with the second bevel gear, causing the bidirectional lead screw to rotate. This causes the threaded block to slide within the fixed plate. Simultaneously, one end of the guide rod is hinged to the bottom of the threaded block, and the other end is hinged to the top surface of the mounting plate. This causes the frame to slide down close to the permalloy shielding shell. Then, the weak magnetic soft magnet is connected to an external power source and the power is turned on, causing the soft magnetic layer to adhere to the bottom of the second stainless steel plate. When the frame approaches the neatly arranged and cleaned permalloy shielding shell, it can be magnetically attracted into the frame, allowing it to be transferred. After being transferred to the designated position, the cylinder is activated, causing the connecting plate to move the traction rod and causing the first stainless steel plate and the weak magnetic soft magnet to rise and slide within the support frame. This causes the soft magnetic layer and the permalloy shielding shell to detach from the second stainless steel plate, thus preventing plastic deformation of the shell caused by strong magnetic field adsorption and avoiding additional losses during product transfer.
[0006] Then, the weak magnetic soft magnet attracts the permalloy shielding shell into the frame, and then the motor is turned on again, causing the shaft to reverse and the frame to rise. This makes it easier to adjust the height of the frame so that products on different platforms can be adjusted, thus facilitating the transfer of the permalloy shielding shell.
[0007] Preferably, a fixing block is fixedly provided on the bottom surface of the mounting plate, the bottom end of the fixing block is fixedly provided on the top surface of the support frame, a groove is provided in the support frame, and positioning blocks are fixedly provided on both sides of the first stainless steel plate, the positioning blocks being slidably provided in the groove.
[0008] Preferably, a fixed plate is fixedly provided on the top surface of the support frame, a bidirectional lead screw is rotatably provided inside the fixed plate, a threaded block is threaded on the outer surface of the bidirectional lead screw, a guide rod is hinged to the bottom surface of the threaded block, and the bottom end of the guide rod is hinged to the top surface of the mounting plate. A rotating shaft is rotatably provided inside the fixed plate, a first bevel gear is fixedly provided on the outer surface of the rotating shaft, a second bevel gear is fixedly provided at one end of the bidirectional lead screw, and the first bevel gear meshes with the second bevel gear. A motor is installed on one side of the fixed plate, and the output end of the motor is fixedly connected to the rotating shaft. Slider blocks are fixedly provided on both sides of the mounting plate, and the sliders are slidably provided inside the support frame. A sliding groove is opened inside the support frame, and a sliding rod is fixedly provided in the sliding groove. The sliders are slidably provided on the outer surface of the sliding rod.
[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0010] 1. When the frame approaches the neatly arranged and cleaned permalloy shielding shell, it can be magnetically attracted into the frame, causing the soft magnetic layer and permalloy shielding shell to enter the frame, thereby avoiding plastic deformation of the shell caused by strong magnetic field adsorption and avoiding additional losses during product transfer.
[0011] 2. As the frame slides down and approaches the permalloy shielding shell, the weak magnetic soft magnet attracts the permalloy shielding shell into the frame. Then the frame rises, making it easier to adjust the height of the frame so that products on different platforms can be adjusted, thus facilitating the transfer of the permalloy shielding shell.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Example: Figure 1-5 As shown, this utility model provides a weak magnetic pull-out type large-area planar iron picker, including a support frame 1, an mounting plate 3 slidably disposed between the support frames 1, a support frame 35 disposed below the mounting plate 3, a first stainless steel plate 36 slidably disposed within the support frame 35, a weak magnetic soft magnet 37 fixedly disposed at the bottom end of the first stainless steel plate 36, a second stainless steel plate 4 fixedly disposed on the bottom surface of the support frame 35, a frame 41 fixedly disposed on the bottom surface of the second stainless steel plate 4, a soft magnetic layer 42 placed inside the frame 41, the soft magnetic layer 42 being tightly attached to the bottom surface of the second stainless steel plate 4; a cylinder 31 is mounted on the top surface of the mounting plate 3, a connecting plate 33 is fixedly disposed at the output end of the cylinder 31, a traction rod 34 is fixedly disposed on the bottom surface of the connecting plate 33, and the traction rod 34 is slidably inserted into the support frame 3. Inside the first stainless steel plate 36, the traction rod 34 is fixed on the top surface of the first stainless steel plate 36. By connecting the weak magnetic soft magnet 37 to an external power source and starting the power, the soft magnetic layer 42 is attracted to the bottom of the second stainless steel plate 4. When the frame 41 approaches the neatly arranged and cleaned permalloy shielding shell, it can be magnetically attracted into the frame 41, thus enabling its transfer. After being transferred to the designated position, the cylinder 31 is activated, causing the connecting plate 33 to move the traction rod 34, which in turn causes the first stainless steel plate 36 and the weak magnetic soft magnet 37 to rise and slide within the support frame 35. This causes the soft magnetic layer 42 and the permalloy shielding shell to detach from the second stainless steel plate 4, thereby avoiding plastic deformation of the shell caused by strong magnetic field attraction and avoiding additional losses during product transfer.
[0021] A fixing block 32 is fixedly provided on the bottom surface of the mounting plate 3. The bottom end of the fixing block 32 is fixedly provided on the top surface of the support frame 35. A groove 351 is provided in the support frame 35. Positioning blocks 38 are fixedly provided on both sides of the first stainless steel plate 36. The positioning blocks 38 are slidably provided in the groove 351.
[0022] By adopting the above technical solution, when the first stainless steel plate 36 slides, it drives the positioning blocks 38 on both sides to slide in the groove 351, thereby assisting the first stainless steel plate 36 and the weak magnetic soft magnet 37 to slide.
[0023] A fixed plate 2 is fixedly mounted on the top surface of the support frame 1. A bidirectional lead screw 24 is rotatably mounted inside the fixed plate 2. A threaded block 25 is threadedly fitted on the outer surface of the bidirectional lead screw 24. A guide rod 26 is hinged to the bottom surface of the threaded block 25. The bottom end of the guide rod 26 is hinged to the top surface of the mounting plate 3. A rotating shaft 22 is rotatably mounted inside the fixed plate 2. A first bevel gear 23 is fixedly fitted on the outer surface of the rotating shaft 22. A second bevel gear 27 is fixedly mounted on one end of the bidirectional lead screw 24. The first bevel gear 23 and the second bevel gear 27 mesh. A motor 21 is mounted on one side of the fixed plate 2. The output end of the motor 21 is fixedly connected to the rotating shaft 22. Slider blocks 12 are fixedly mounted on both sides of the mounting plate 3. The sliders 12 are slidably mounted inside the support frame 1. A sliding groove 101 is opened inside the support frame 1. A sliding rod 11 is fixedly mounted inside the sliding groove 101. The slider 12 is slidably mounted on the outer surface of the sliding rod 11.
[0024] By adopting the above technical solution, when transfer is required, the motor 21 is turned on, causing the rotating shaft 22 to rotate, which in turn drives the first bevel gear 23 to rotate. The first bevel gear 23 meshes with the second bevel gear 27, thereby causing the bidirectional lead screw 24 to rotate, causing the threaded block 25 to slide within the fixed plate 2. At the same time, one end of the guide rod 26 is hinged to the bottom end of the threaded block 25, and the other end of the guide rod 26 is hinged to the top surface of the mounting plate 3, thereby causing the frame 41 to slide down and approach the permalloy shielding shell. This allows the weak magnetic soft magnet 37 to attract the permalloy shielding shell into the frame 41. Then, the motor 21 is turned on again, causing the rotating shaft 22 to reverse, thereby causing the frame 41 to rise. This facilitates the adjustment of the height of the frame 41, enabling adjustments to products on different platforms, and thus facilitating the transfer of the permalloy shielding shell.
[0025] Working principle: First, when transfer is required, the device is moved below the permalloy shielding shell. Then, by turning on the motor 21, the rotating shaft 22 rotates, driving the first bevel gear 23 to rotate. The first bevel gear 23 meshes with the second bevel gear 27, causing the bidirectional lead screw 24 to rotate. This causes the threaded block 25 to slide within the fixed plate 2. Simultaneously, one end of the guide rod 26 is hinged to the bottom of the threaded block 25, and the other end is hinged to the top surface of the mounting plate 3. This causes the frame 41 to slide down close to the permalloy shielding shell. Then, the weak magnetic soft magnet 37 is connected to an external power source, and the power supply is started. This allows the soft magnetic layer 42 to be adsorbed onto the bottom of the second stainless steel plate 4. When the frame 41 approaches the neatly arranged and cleaned permalloy shielding shell, it can be magnetically attracted into the frame 41, thus enabling its transfer. After being transferred to the designated position, the cylinder 31 is activated, causing the connecting plate 33 to move the traction rod 34, which in turn causes the first stainless steel plate 36 and the weak magnetic soft magnet 37 to rise and slide within the support frame 35. This causes the soft magnetic layer 42 and the permalloy shielding shell to detach from the second stainless steel plate 4, thereby preventing the shell from being plastically deformed due to strong magnetic field adsorption and avoiding additional losses during product transfer.
[0026] Then, the weak magnetic soft magnet 37 attracts the permalloy shielding shell into the frame 41, and then the motor 21 is turned on again, causing the rotating shaft 22 to reverse, thereby raising the frame 41. This makes it easier to adjust the height of the frame 41 so that products on different platforms can be adjusted, thus facilitating the transfer of the permalloy shielding shell.
