Description

Technical Field

[0001] This utility model relates to the field of magnetic steel bonding mold technology, and more specifically, to a Heilbeck-type array modular magnetic steel bonding mold. Background Technology

[0002] Hellbeck arrays are magnetic structures, near-ideal engineering structures designed to generate strong magnetic fields with a small number of magnets. They are further divided into linear arrays and ring arrays. Linear arrays consist of basic Hellbeck arrays; this type of array can be considered a combination of radial and tangential arrays. They are mainly used in linear motors, magnetic levitation trains, and other fields. Some existing modular Hellbeck array magnet products include a base plate. Multiple main magnets arranged at intervals are first bonded to the base plate with adhesive, and then auxiliary magnets are bonded to the slots between adjacent main magnets. During installation, the repulsive force between like poles increases the difficulty of installation, making it hard to correctly align the main / auxiliary magnets. Operators also need considerable strength to adjust the magnets' positions, hindering the bonding process. Furthermore, the attraction between opposite poles during bonding can cause rapid magnet adsorption, leading to impact damage, surface scratches, or mis-adhesion. Manual assembly is slow and difficult to precisely control due to the repulsion and attraction between like and opposite poles, making it unsuitable for mass production and compromising product performance and reliability. Utility Model Content

[0003] To address at least one of the aforementioned problems, this utility model provides a Hellbeck-style modular magnet bonding mold, comprising a main magnet mounting mechanism suitable for bonding a plurality of main magnets at intervals to a base plate. The main magnet mounting mechanism includes a mounting base, a main magnet positioning plate, and a plurality of auxiliary magnet prostheses. The base plate and the main magnet positioning plate are both connected to the mounting base, with the base plate positioned between the main magnet positioning plate and the mounting base. The auxiliary magnet prostheses are spaced apart on the side of the main magnet positioning plate closest to the base plate. The base plate is provided with a mounting surface for bonding the main magnets. The steel bonding portion includes a through groove on the main magnet positioning plate corresponding to the bonding portion. When bonding the main magnet, adhesive is applied to the bonding portion through the through groove, and the main magnet is passed through the through groove to the bonding portion for bonding. The auxiliary magnet prosthesis is used to limit the movement of the main magnet passing through the through groove. This utility model, a Heilbeck array modular magnet bonding mold, is equipped with a main magnet mounting mechanism and an auxiliary magnet mounting mechanism, making it less prone to displacement of the main and auxiliary magnets during their respective bonding operations, resulting in more accurate bonding positions, convenient operation, and improved product reliability.

[0004] Optionally, the mounting base is provided with two limiting blocks, and the base plate is placed between the two limiting blocks for limiting.

[0005] Optionally, a first bolt connects the base plate, the mounting base, and the main magnet positioning plate. The base plate is provided with a first bolt hole for installing the first bolt, the mounting base is provided with a second bolt hole for installing the first bolt, and the main magnet positioning plate is provided with a third bolt hole for installing the first bolt.

[0006] Optionally, a second bolt connects the auxiliary magnet prosthesis to the main magnet positioning plate, the auxiliary magnet prosthesis is provided with a fourth bolt hole for installing the second bolt, and the main magnet positioning plate is provided with a fifth bolt hole for installing the second bolt.

[0007] Optionally, the Heilbeck-type modular magnet bonding mold further includes a secondary magnet mounting mechanism suitable for bonding several secondary magnets to the base plate. The secondary magnets are bonded in the gap groove between two adjacent main magnets. The secondary magnet mounting mechanism includes a mounting plate and a secondary magnet positioning plate disposed on the mounting plate. The base plate is detachably connected to the mounting plate. The secondary magnet positioning plate is provided with a positioning groove communicating with the gap groove. A limit cover plate is connected between the mounting plate and the secondary magnet positioning plate. The limit cover plate is used to limit the secondary magnets in the gap groove and the positioning groove. When bonding the secondary magnets, an adhesive is applied to the bottom surface of the gap groove, the secondary magnets are placed into the positioning groove, and an external force drives the secondary magnets to enter the gap groove along the positioning groove.

[0008] Optionally, the mounting plate is provided with a first mounting block, the first mounting block is provided with a mounting groove, one end of the limiting cover is placed in the mounting groove, and the other end of the limiting cover is connected to the auxiliary magnet positioning plate.

[0009] Optionally, a wedge-shaped pull block is slidably disposed on the first mounting block, and a slow-descent ramp is disposed on the side of the wedge-shaped pull block near the auxiliary magnet, and a clearance groove for avoiding the adhesive on the bottom surface of the groove is disposed on the side of the wedge-shaped pull block near the base plate.

[0010] Optionally, the bottom of the positioning groove is provided with a guide slope.

[0011] Optionally, the mounting plate is provided with a driving mechanism, which is used to drive the auxiliary magnet in the positioning groove into the gap groove. The driving mechanism includes a second mounting block disposed on the mounting plate and a driving bolt threadedly connected to the second mounting block.

[0012] Optionally, an anti-scratch block is placed between one end of the drive bolt and the auxiliary magnet.

[0013] Compared to existing technologies, the Heilbeck-style modular magnet bonding mold of this invention features a main magnet mounting mechanism and a secondary magnet mounting mechanism. This design minimizes displacement of the main and secondary magnets during their respective bonding operations, resulting in more accurate bonding positions, easier operation, and improved product reliability. The mounting base has two limiting blocks, with the base plate positioned between them for positioning, further preventing displacement of the base plate and enhancing the accuracy of the main magnet's installation position. A limiting cover plate connects the mounting plate and the secondary magnet positioning plate, limiting the secondary magnet within the gap and positioning grooves to prevent displacement due to magnetic repulsion during the pushing process. After the secondary magnet is pushed into the gap groove and positioning groove, it will be attracted and held in the gap groove by a magnetic force. A slow-descent ramp is provided on the side of the wedge-shaped pull block near the secondary magnet. When the secondary magnet completely detaches from the positioning groove and enters the gap groove, the wedge-shaped pull block is pulled out by external force. During this process, the slow-descent ramp ensures that one end of the secondary magnet contacts the bottom surface of the gap groove first, and the other end slowly contacts the bottom surface of the gap groove. This prevents the secondary magnet from colliding with the bottom surface of the gap groove due to the magnetic force, thus improving the product yield and reliability. An anti-scratch block is placed between one end of the drive bolt and the secondary magnet to prevent the drive bolt from scratching the secondary magnet, improving product quality.

[0027] See Figures 1-5 The mounting base 3 is equipped with two limiting blocks 301. The base plate 2 is placed between the two limiting blocks 301 for limiting, so that the base plate 2 is not easy to move and improves the accuracy of the installation position of the main magnet 1.

The mounting base is equipped with two limiting blocks, and the base plate is placed between the two limiting blocks for restraint, preventing the base plate from shifting and improving the accuracy of the main magnet's installation position. A limiting cover plate connects the mounting plate and the secondary magnet positioning plate, which is used to limit the secondary magnet in the gap groove and positioning groove, preventing the secondary magnet from shifting out of the gap due to magnetic repulsion during the pushing process. The slot and positioning slot are designed so that when the auxiliary magnet is pushed into the slot, it will be attracted and held in the slot. A slow-descent ramp is provided on the side of the wedge-shaped pull block near the auxiliary magnet. When the auxiliary magnet completely detaches from the positioning slot and enters the slot, external force pulls out the wedge-shaped pull block. During this process, the slow-descent ramp ensures that one end of the auxiliary magnet contacts the bottom surface of the slot first, and the other end slowly contacts the bottom surface of the slot, preventing the auxiliary magnet from colliding with the bottom surface of the slot due to attraction and thus avoiding damage. This improves the product yield and reliability.
