Description

Technical Field

[0001] The present application relates to the field of iron core technology, and in particular to a manufacturing system for a glue-coated part and an iron core. Background Art

[0002] The motor core is generally made of multiple stacked electrical steels. During the manufacturing process of the motor core, the electrical steel is generally processed in two steps. The first step is to coat the electrical steel with glue, then solidify, cool and roll the coated electrical steel. The second step is to use a stamping die to stamp, stack and bond the electrical steel processed in the first step. The reason for the two-step process is that during the stamping process, the punch in the stamping die will punch the electrical steel. If the glued electrical steel is not cured, the punch may become glued during the stamping process, affecting the subsequent use of the stamping die. It is impossible to punch holes while coating glue, which makes the manufacturing process of the motor core complicated and the manufacturing cost high.

[0003] At present, in the process of gluing, glue is generally applied by dispensing glue or surface glue. However, these two methods also have defects. The former is prone to serious glue overflow during the stamping process, affecting the overall performance of the motor core. The latter is prone to uneven and insufficient bonding strength of the motor core and serious waste of glue. Utility Model Content

[0004] In order to solve the above-mentioned deficiencies of the prior art, the first purpose of the present application is to provide a glue-coated part that is conducive to stamping electrical steel while applying glue, and the glue-coated part can not only improve the bonding strength between electrical steels, but also reduce the waste of glue and reduce the manufacturing cost of the iron core.

[0005] The present application is implemented through the following technical solutions: a glue coating part, which is used to coat electrical steel with glue, the glue coating part is a glue coating roller, the glue coating roller can rotate axially, the outer circumferential surface of the glue coating roller is provided with a glue coating area and a shielding area, the glue coating area is located on the same circumferential surface, the glue coating area is used to bond glue and coat the electrical steel with glue, the distance from the glue coating area to the central axis of the glue coating roller is greater than the distance from the shielding area to the central axis of the glue coating roller; or the glue coating part is a glue coating block, the glue coating block can move vertically up and down, the glue coating block includes a lower end surface, the lower end surface is provided with a glue coating area and a shielding area, the glue coating area is located on the same plane, the glue coating area is used to bond glue and coat the electrical steel with glue, and the glue coating area is located below the shielding area.

[0006] The second object of the present application is to provide a core manufacturing system, comprising a feeder, a glue coating device and a stamping mold arranged in sequence, the glue coating device comprises a support member and the glue coating member, the glue coating member and the support member are arranged up and down, the electrical steel is mounted above the support member for transmission and movement, and the glue coating member glues the electrical steel during transmission and movement.

[0007] Furthermore, a curing device is provided between the gluing device and the stamping die.

[0008] Furthermore, a cooling device is provided between the curing device and the stamping die.

[0009] Furthermore, a heating and pressurizing device is also provided in the stamping die.

[0010] The present application sets a gluing area and a shielding area on the gluing part. The shielding area corresponds to the punching holes on the electrical steel. The gluing area is coated with glue to avoid the glue coating at the corresponding position of the punching holes. After the gluing treatment, the stamping mold can be directly used for stamping, and the punch will not be sticky. The technical effect of stamping while gluing is achieved, which simplifies the manufacturing process of the iron core, shortens the manufacturing time of the iron core, and reduces the manufacturing cost of the iron core. On the basis of ensuring the bonding strength between the electrical steels, the amount of glue used is greatly reduced, further reducing the manufacturing cost of the iron core.

[0026] The following is a detailed description of a manufacturing system of a glue-coated part and an iron core of the present application in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments can be combined with each other. Example 1

[0027] Please refer to Figure 1 , 2 As shown, the present application provides a glue coating part, which is used to coat electrical steel 8 with glue. The glue coating part is a glue coating roller 1. The glue coating roller 1 is cylindrical and can rotate axially. The outer circumferential surface of the glue coating roller 1 is provided with a glue coating area 4 and a shielding area 5. The glue coating area 4 is used to bond glue and coat the electrical steel 8 with glue. The glue coating area 4 is located on the same circumferential surface to ensure the uniformity of the glue coating of the electrical steel by the glue coating area 4. The distance from the glue coating area 4 to the central axis of the glue coating roller 1 is greater than the distance from the shielding area 5 to the central axis of the glue coating roller 1.

[0028] The glue coating area 4 can be convexly arranged on the outer peripheral surface of the glue coating roller 1, or it can be the outer peripheral surface of the glue coating roller 1. When the glue coating area 4 is the former, the outer peripheral surface of the glue coating roller 1 is provided with a first convex block or a fixed sleeve is provided with a convex ring 6, and the first convex block or the convex ring 6 is away from one end of the outer peripheral surface of the glue coating roller 1 to form the glue coating area 4, and the shielding area 5 can be the outer peripheral surface of the glue coating roller 1, please refer to Figure 1 As shown, the shielding area 5 can also be recessed on the outer peripheral surface of the glue coating roller 1, and the shielding area 5 can also be convexly disposed on the outer peripheral surface of the glue coating roller 1. At this time, the convex height of the shielding area 5 is less than the height of the first protrusion or the convex ring 6. When the glue coating area 4 is the latter, the shielding area 5 is recessed on the outer peripheral surface of the glue coating roller 1. Example 2

[0029] Please refer to Figure 3 , 4 As shown, the difference between this embodiment and embodiment 1 is that the glue coating part is a glue coating block 2, the glue coating block 2 can move vertically up and down, the glue coating block 2 includes a lower end surface 3, and the lower end surface 3 is provided with a glue coating area 4 and a shielding area 5, the glue coating area 4 is located on the same plane, the glue coating area 4 is used for bonding glue and gluing the electrical steel 8, and the glue coating area 4 is arranged below the shielding area 5.

[0030] The shape of the glue coating block 2 is not limited, and the shape of the lower end surface 3 is also not limited.

[0031] The glue coating area 4 can be convexly arranged on the lower end surface 3 of the glue coating block 2, or it can be the lower end surface 3 of the glue coating block 2. When the glue coating area 4 is the former, a plurality of second protrusions 7 are provided on the lower end surface 3 of the glue coating block 2. The second protrusion 7 is flat at one end away from the glue coating block 2 and forms the glue coating area 4. The shielding area 5 can be the lower end surface 3 of the glue coating block 2, or the shielding area 5 can also be concavely arranged on the lower end surface 3 of the glue coating block 2, or the shielding area 5 can also be convexly arranged on the lower end surface 3 of the glue coating block 2. At this time, the height of the shielding area 5 is less than the height of the second protrusion 7. When the glue coating area 4 is the latter, the shielding area 5 is concavely arranged on the lower end surface 3 of the glue coating block 2. Example 3

[0032] Please refer to Figures 5 to 8 As shown, this embodiment provides a core manufacturing system, including a feeder 9, a glue coating device 10 and a stamping mold 11 which are arranged in sequence, the glue coating device 10 includes a support member 12 and the glue coating member, the glue coating member and the support member 12 are arranged up and down, the electrical steel 8 is mounted above the support member 12 for transmission and movement, and the glue coating member glues the electrical steel 8 during transmission and movement.

[0033] The feeder 9 drives the electrical steel 8 to move along the conveying path, and the stamping die 11 stamps, stacks and bonds the electrical steel after being coated with glue to form an iron core. The feeder 9 and the stamping die 11 are the same as the existing technology and will not be described in detail here.

[0034] The glue coating part in the glue coating device 10 is the glue coating roller 1 in Example 1 or the glue coating block 2 in Example 2. The glue coating roller 1 or the glue coating block 2 is used to coat the electrical steel 8 with glue. The glue coating area 4 is used to coat the electrical steel 8 with glue. The shielding area 5 corresponds to the punching position of the electrical steel. The shielding area 5 does not contact the electrical steel, that is, the position corresponding to the punching is not coated with glue, so that the electrical steel can be directly stamped after being coated with glue. Since the position corresponding to the punch in the stamping mold is not coated with glue, the punch will not have the problem of sticking glue, and the electrical steel does not need to be processed in steps. The technical effect of stamping while coating with glue can be achieved, shortening the manufacturing process and manufacturing time of the iron core, and greatly reducing the manufacturing cost.

[0035] The area of ​​the glue coating zone 4 is generally much smaller than that of the electrical steel coated with surface glue, which not only ensures the bonding strength between the electrical steels, but also greatly reduces the amount of glue used. After extensive use by the inventor, the amount of glue used in manufacturing the iron core using this manufacturing method can be reduced by at least 60% under the same bonding strength compared to the iron core manufactured by surface glue coating, and can even be reduced to more than 70%.

[0036] The area of ​​the glue coating area 4 is much larger than that of the electrical steel glue coating method using glue dot coating. The glue coating area is arranged at the periphery of the shielding area, and part of the glue coating area is close to the shielding area corresponding to the tooth part in the punching hole. Such an arrangement can not only improve the bonding strength between the electrical steels, but also effectively solve the serious problem of glue overflow, and can improve the overall performance of the iron core.

[0037] In order to facilitate the transport and movement of the electrical steel, the support member 12 is generally a cylinder, and can be a plurality of closely arranged or a plurality of spaced arrangements.

[0038] The core manufacturing system further includes a material puller 13, which is arranged behind the stamping die 11 and is used to pull the stamped electrical steel scrap so that the electrical steel can move smoothly along the conveying path. Of course, the material puller 13 is not necessary. Example 4

[0039] Please refer to Figures 5 to 8As shown, the difference between this embodiment and embodiment 3 is that the manufacturing system of the iron core also includes a curing device 14, and the curing device 14 is arranged between the glue coating device 10 and the stamping forming mold 11. The curing device 14 is used to cure the glue coated on the electrical steel 8. The curing device 14 is also the same as the prior art and will not be described in detail here.

[0040] Of course, the curing device 14 can be room temperature curing or heating curing. When room temperature curing is adopted, the curing device may not be installed, and the transmission line between the glue coating device 10 and the stamping forming mold 11 may be extended. Please refer to Figure 5 As shown, when heating curing is adopted, a cooling device 15 can also be arranged between the curing device 14 and the stamping forming die 11. The cooling device 15 is used to cool the electrical steel after heating and curing. The cooling device 15 is also the same as the prior art and will not be described in detail here.

[0041] Regardless of whether it is room temperature curing or heating curing, where the curing temperature is lower than the heating temperature in the stamping die 11, the curing device 14 only has a preliminary curing effect, that is, without the curing device 14, it can also be supplied to the stamping die 11 for stamping, stacking and bonding. If it is first cured by the curing device 14, the fluidity of the glue between the electrical steels in the stamping die can be reduced, thereby further ensuring the overall performance of the core after forming.

[0042] The curing device 14 and the heating and pressurizing device in the stamping mold 11 in this embodiment are arranged because the glue for the gluing process is epoxy glue, while the curing device and the heating and pressurizing device are not used in the embodiment 3 because the glue for the gluing process is anaerobic glue. The heating and pressurizing device is also the same as the prior art, and will not be described in detail here.

[0043] In both Example 4 and Example 3, the glue coating parts in Example 1 or Example 2 are used. During the transmission of the electrical steel, the glue coating roller 1 rotates at a certain frequency to coat the glue on the electrical steel, or the glue coating block 2 moves up and down at a certain frequency to coat the glue on the electrical steel. The electrical steel after coating is subsequently processed to achieve the technical effect of stamping while coating, thereby solving the technical problem that the glue cannot be preserved for a long time after coating.

[0044] The above is only a preferred embodiment of the present application and does not constitute any form of limitation to the present application. Although the present application has been disclosed as a preferred embodiment as above, it is not intended to limit the present application. Any technician familiar with the profession can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present application. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present application without departing from the content of the technical solution of the present application still falls within the scope of the technical solution of the present application.
