Description
Technical Field
The invention relates to the technical field of linear motors, in particular to a method for manufacturing a stator core for a linear motor.
Background
The existing stator core for the linear motor is formed by stacking a plurality of pieces of core base materials, and then the core base materials are fixedly connected in a riveting mode, so that some core base materials are tightly attached to each other. However, the conventional riveting method is obviously difficult to form the stator core into the structure. Therefore, epoxy resin glue is used for bonding the iron core base material in the prior art so as to improve the output value of the motor. The stator core is mostly a hollow structure with teeth, and the structure is the prior art.
In the traditional glue coating process, the glue is uniformly coated on the surface of a steel plate or an iron core substrate by adopting a roller or spraying process. But is applied to manufacturing the linear motor iron core. The problem that results from this process is that, after the glue melts during the thermocompression bonding process, part of the glue is squeezed out from the edges of the two adjacent core substrates, thereby affecting the dimensional tolerance of the final core teeth. The tolerance of the iron core tooth part is too large, so that the enameled wire coil is difficult to be matched with the stator iron core of the original model for installation, if the enameled wire coil is normally installed, the size of the enameled wire coil can be only increased, the number of the enameled wire coils which can be installed on the stator iron core is reduced, and the output power of the motor is influenced.
Accordingly, the prior art is yet to be improved and developed.

In order to solve the above technical problem, as shown in fig. 1, the present invention provides a method for manufacturing a stator core for a linear motor, including the steps of:
step S1: the method comprises the steps of enclosing a first plane on the surface of a steel plate, enabling a first vertical projection of an iron core substrate forming a stator iron core on the surface of the steel plate to coincide with the first plane, laying the iron core substrate on the surface of the steel plate by utilizing a silk screen, processing a second plane on the surface of the silk screen, enabling a plurality of glue filtering holes to be formed in the second plane, enabling a second vertical projection of the iron core substrate on the surface of the silk screen to fall into the second plane, enabling the outline shape of the second vertical projection to be the same as that of the second plane, spraying epoxy resin glue on the second plane, and enabling the epoxy resin glue to fall into the first plane after penetrating through the glue filtering holes;
step S2: the steel plate in the step S1 is sent to a constant temperature environment for heating;
step S3: making the steel plate in the step S2 into a plurality of iron core base materials for forming the stator iron core, wherein the surface of the iron core base material is provided with an epoxy resin glue layer with the same thickness as the surface of the steel plate in the step S1;
step S4: conveying the iron core base materials in the step S3 into a die device for stacking and extruding;
step S5: the multiple iron core substrates in the step S4 are sent to a constant temperature environment for heating;
step S6: and (5) placing the iron core substrate heated in the step (S5) in air for curing to obtain the stator iron core.
The traditional glue coating process is to uniformly coat the glue on the whole surface of a plate by adopting a roller or a spraying process. However, when the process is applied to bonding of multiple iron core base materials for manufacturing the linear motor iron core, the problem caused by the process is that in the process of hot pressing the iron core, after glue is heated and melted, part of the glue can be extruded from the edges of the two adjacent iron core base materials, and therefore the dimensional tolerance of the final iron core tooth part is affected. The tolerance of the iron core tooth part is too large, so that the enameled wire coil is difficult to be matched with the stator iron core of the original model for installation, if the enameled wire coil is normally installed, the size of the enameled wire coil can be only increased, the number of the enameled wire coils which can be installed on the stator iron core is reduced, and the output power of the motor is influenced. Therefore, the process adopted by the invention is to utilize a screen 2 to process the second plane 3, the second plane 3 is provided with a plurality of glue filtering holes (not shown in the figure), and the epoxy resin glue layer falls into the first plane 4 of the surface of the steel plate 1 (because the section describes the processing mode of the steel plate 1, the steel plate 1 is only marked in the section) after passing through the glue filtering holes, so that the coating range of the glue is controlled to be slightly smaller than the edge of the iron core substrate, and the glue cannot overflow from the edge of the iron core substrate during hot-press bonding. Thereby ensuring the final size of the core. And taking out the silk screen 2 after the glue is coated.
In the invention, the thickness of the epoxy resin adhesive layer on the surface of the steel plate in the step S1 is 0.2-1 mm. In the step S2, the steel plate is heated in a thermostat at the heating temperature of 40-80 ℃ for 20-120 min. In step S3, the steel sheet in step S2 may be cut by a laser cutter, or the steel sheet in step S2 may be fed into a die press and processed into a multi-piece core base material. Before the step S4, a forming and positioning mold device with a certain depth can be manufactured according to the shape of the iron core base material, in the step S4, the iron core base material in the step S3 can be stacked in the forming and positioning mold device piece by a manipulator, and then the iron core base material is pressed by a punching machine falling from the top, so that the bonding among the multiple layers of iron core base materials is firm, in the step S4, the surface pressure of the iron core base material is 5-25 KN, and the pressing force is controlled within the value range, so that the iron core base material can be prevented from being pressed and deformed, and a good bonding effect is achieved. In the step S5, the iron core substrate is heated in a thermostat at the heating temperature of 120-220 ℃ for 0.5-2 h. The stator core manufactured by the method has the advantages that the epoxy resin glue layers are arranged among the core substrates for bonding, the core substrates are prevented from being conducted with each other, the magnetic field can be cut independently, and each core substrate is fully utilized, so that the output value of the motor can be greatly improved when the stator core is used for manufacturing the linear motor.
