UTILITY MODEL CONTENT

[0004] The utility model aims at providing a dustproof magnetic track of linear motor to solve the problems in the above background.

[0005] To achieve the above object, the utility model provides the following technical scheme:

[0006] A dustproof magnetic track of linear motor, including yoke and a plurality of magnets, a plurality of the magnets are arranged at intervals on the yoke, and the magnets are fixedly connected with the yoke, a plurality of the magnets are provided with gaps, the gaps are filled with colloid, and the colloid is used to fill the gaps between the magnets.

[0007] Further technical scheme, the magnet is rubidium magnetic sticker, the side of the rubidium magnetic sticker towards the yoke is smeared with glue, and the rubidium magnetic sticker is pasted with the yoke through glue.

[0008] Further technical scheme, the colloid is plastic filling spacer, and the plastic filling spacer is made of POM material.

[0009] Further technical scheme, the yoke is made of S45C material.

[0010] Further technical scheme, the plastic filling spacer includes conical plastic strip.

[0011] Further technical scheme, the length of the plastic filling spacer ranges from 67.4cm to 67.6cm.

[0012] In a further technical solution, the width of the plastic filler spacer ranges from 1.97cm to 2.03cm.

[0013] In a further technical solution, the height of the plastic filler spacer ranges from 3.5cm to 3.7cm.

[0014] The beneficial effects of this utility model are:

[0015] During assembly, this invention first places several magnets on an assembly plate with spaced teeth. Notably, the magnets are neodymium magnets, with adhesive applied to the side of the magnet facing the yoke. The yoke is then placed on the assembly plate, allowing the neodymium magnets to adhere to the yoke with adhesive. This ensures the magnets and yoke remain in a fixed position. Several adhesive bodies are pre-made using a plastic mold and then inserted sequentially between two magnets to fill the gaps, preventing foreign objects from falling into the gaps and affecting magnetism and mover movement. Compared to the process of attaching a stainless steel cover plate after the magnets are attached, this magnetic track structure eliminates the curing and pressure holding processes, preventing the risk of damaging the magnetic track structure during pressure holding and reducing the cost of cleaning the stainless steel cover plate and removing the protective film. Compared to filling the gaps between magnets with epoxy resin after the magnets are attached, this device eliminates the processes of setting glue-filling limits, using special glue-filling equipment, and waiting for the glue to cure, reducing the time required to clean the glue-filling limit tape.

[0016] Other features and advantages of this invention will be described in detail in the following detailed description section. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Please refer to Figures 1-3 ;

[0023] To prevent foreign objects from falling through the gap between the magnets 2 of the magnetic rail and damaging the magnetism, existing magnetic rails typically undergo two processes after manufacturing:

[0024] The first process involves attaching a stainless steel cover plate after magnet 2 is applied. However, attaching the stainless steel cover plate requires a relatively long curing time, with the adhesive needing to be pressurized for at least 25 minutes during curing, and a special fixture is required for on-site pressurization. Furthermore, the stainless steel cover plate is prone to appearance and functional abnormalities during pressurization, resulting in a low tolerance for error. There are also issues with cleaning the stainless steel cover plate and removing the protective film, which is relatively time-consuming and leads to higher management costs. Pressurized stainless steel cover plates occupy production space, and the small installation gaps result in low versatility.

[0025] The first process involves filling the spaces between magnets 2 after they are attached with epoxy resin and allowing it to cure. However, before filling the space with the resin, it is necessary to set the filling limit, which takes a relatively long time. It also requires the use of special filling equipment. The process involves mixing the resin according to the specified ratio and vacuuming the resin, which is complicated and requires a relatively high level of technical expertise. Furthermore, the resin takes a long time to cure after filling, requiring more than 4 hours for natural air drying and more than 2 hours for oven baking. There are also issues with the limited number of units that can be baked in the oven, relatively high safety risks, and the time-consuming cleaning of the filling limit after filling.

[0026] Therefore, this application discloses a dustproof magnetic track for a linear motor, aiming to save time and simplify operation. It includes a magnetic yoke 1 and several magnets 2. The magnetic yoke 1 is made of S45C material. Several magnets 2 are arranged at intervals on the magnetic yoke 1 and are fixedly connected to the magnetic yoke 1. There is a gap 3 between several magnets 2. The gap 3 is filled with a colloid 4. The colloid 4 is used to fill the gap 3 between the magnets 2. The colloid 4 can be a hard glue. The hard glue is inserted into the gap 3 to fill the gap 3 and prevent external debris from falling into the gap 3 and damaging the magnetism. However, the use of hard glue may cause tiny, imperceptible gaps in the gap 3, making the hard glue unstable and easy to fall off, and easy to accumulate tiny dust, resulting in a decrease in magnetism. Furthermore, the colloid 4 is a plastic filler septum 41, which is made of POM material.

[0027] During assembly, first, several magnets 2 are placed on an assembly plate (not shown in the figure) with spaced teeth. It is worth noting that the magnets 2 are neodymium magnets, and glue is applied to the side of the neodymium magnet facing the yoke 1. Then, the yoke 1 is placed on the assembly plate, so that the neodymium magnet and the yoke 1 are glued together. This ensures that the positions of the magnets 2 and the yoke 1 are fixed. Several colloids 4 are pre-made using a plastic mold, and then the colloids 4 are inserted sequentially between two magnets 2, filling the gap 3 to prevent foreign objects from falling into the gap 3 and affecting the magnetism. Compared to the process of attaching a stainless steel cover plate after magnet 2 is attached, this magnetic track structure eliminates the curing and pressure holding processes, preventing the risk of damaging the magnetic track structure during pressure holding and reducing the cost of cleaning the stainless steel cover plate and removing the protective film. Compared to the process of filling the space between magnet 2 with epoxy resin after magnet 2 is attached, this device eliminates the processes of setting glue limiters, using special glue filling equipment, and waiting for the glue to cure after filling, reducing the time required to clean the glue limiter tape after filling.

[0028] In this embodiment, the plastic filling spacer 41 includes a frustoconical plastic strip 411. The length of the plastic filling spacer 41 ranges from 67.4cm to 67.6cm, the width of the plastic filling spacer 41 ranges from 1.97cm to 2.03cm, and the height of the plastic filling spacer 41 ranges from 3.5cm to 3.7cm.

[0029] Specifically, the length of the plastic filler 41 is preferably 67.5cm, the width of the plastic filler 41 is preferably 2cm, and the height of the plastic filler 41 is preferably 3.6cm. When the plastic filler 41 is inserted into the gap 3 between the magnets 2, the frustum plastic strip 411 can be inserted downwards to improve the ease of insertion and the efficiency of insertion. In addition, the frustum plastic strip 411 can also be inserted from the left or right side of the magnet 2.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
