This increases the number of steps in manufacturing the motor and makes it more complicated. In order to improve the heat dissipation effect of the motor, the length of the iron core is usually extended, but this will reduce the output force of the motor. Summary of the invention

[0007] Preferably, the glue filling port extends upward to form a baffle, and the glue filling port is axially arranged on the upper cover shell; through the arrangement of the above-mentioned baffle, an obstacle can be added for the filling of the colloid to avoid splashing outside and causing waste during glue filling, and to avoid overflow of the colloid after filling, so that it is difficult to clean after the colloid dries.
[0008] Preferably, the stator is formed by splicing a plurality of stator teeth in a ring shape, and a coil skeleton is inserted into the top and bottom ends of each stator tooth; through the arrangement of the above-mentioned stator teeth, the stator can be spliced, which is convenient for replacement and maintenance of damaged stators or coils, and is convenient for production and cost saving. The arrangement of the coil skeleton can increase the protection of the stator, reduce the loss of the coil to the stator, and facilitate the glue filling and sealing and fixing of the upper and lower cover shells by cooperating with the structure of the upper and lower cover shells.
[0009] Preferably, each of the stator teeth and every two of the coil frames are wound with a coil winding, and the wire ends of the coil windings are centrally led out of the glue filling port through the circuit board; through the above-mentioned setting of the coil windings, the circuit can be sorted out to avoid mutual interference between the windings to increase the circuit burden and improve the current output effect.
[0010] Preferably, the stator is fixed in the casing by an interference fit with the casing; the interference fit can strengthen the fastening force between the stator and the casing, facilitate the assembly of the stator, effectively strengthen the fixing force, and avoid damage and influence on the fixed colloid when the bolts are fixed.
[0011] Preferably, a strip groove is provided on the outer side of each stator tooth; by providing the strip groove, when the stator and the housing are interference fit, the deformation capacity of the stator is increased to avoid damage to the stator due to excessive extrusion of the stator.
[0012] The present invention has the following advantages: through the arrangement of the above-mentioned structure, the device can avoid the tedious enameling of the coil, so that the copper wire of the coil is directly wound on the stator and then infiltrated and wrapped by the sealant to achieve the insulation effect, and the gap between the stators can be sealed, which can play a certain waterproof role while isolating oxygen to avoid oxidation of the coil, and the colloid can improve the heat dissipation effect, shorten the length of the iron core, and improve the output force of the motor.

[0016] like Figure 1-3As shown, a cutting motor for mask production includes a casing 1, a front cover 12 and a rear cover 11 fixed above the two ends of the casing 1, a stator 21 arranged in the casing 1, and a rotor 13 arranged in the stator, wherein the two ends of the stator 21 are respectively provided with an upper cover shell 22 and a lower cover shell 23, and the gap enclosed by the stator, the upper cover shell 22 and the lower cover shell 23 is filled with glue, and the upper cover shell 22 and the lower cover shell 23 are fixed to the two ends of the stator 21 by the glue. Through the coordinated arrangement of the upper cover shell and the lower cover shell, and the glue treatment, the coil winding in the above-mentioned motor can be thoroughly insulated and wrapped by the glue penetration, avoiding the trouble of painting the coil, and can play a certain waterproof role, and at the same time can improve the heat dissipation effect of the motor, so that the manufacturing length of the iron core can be shorter, thereby increasing the current and improving the output force of the motor.
[0017] like Figure 2 As shown, a glue injection port 231 is provided on the top surface of the upper cover shell 23, and glue is injected from the glue injection port 231 to fill the gaps between the stator 21, the upper cover shell (22) and the lower cover shell 23. The glue injection port 231 extends upward to form a stopper. The glue injection port 231 is axially arranged on the upper cover shell 23. Through the setting of the above-mentioned glue injection port, the glue can be injected therefrom, providing a glue injection path, and at the same time, a lead-out port for the coil can be provided to ensure the sealing of the coil winding. Through the setting of the above-mentioned stopper, an additional barrier can be provided for the injection of the glue, thereby avoiding splashing of the glue outside during injection and causing waste, and avoiding overflow of the glue after injection, so that the glue is difficult to clean after drying.
[0018] Before glue pouring, insert a core rod in the middle of the stator, and use nuts at both ends of the core rod to press the upper and lower covers onto the stator core and cover the windings. Then pour the glue through the glue pouring port to allow the glue to penetrate completely. After a certain period of time, the glue solidifies and the stator and the casing are fixed together by heat fitting. The two side walls of the upper and lower covers are matched with the structure of the coil skeleton to ensure the closed fit of the upper and lower covers to the stator and the stability of the glue pouring seal.
[0019] like Figure 2 As shown, the stator 21 is fixed in the casing 1 by an interference fit with the casing 1. By setting the interference fit, the fastening force between the stator and the casing can be strengthened, which facilitates the assembly of the stator, effectively strengthens the fixing force, and avoids damage and influence on the fixed colloid when the bolts are fixed. The interference fit adopts a heat fit method, and the fixation between the stator and the casing can also adopt a snap fit method.
[0020] like Figure 2-3As shown, the stator 21 is formed by a plurality of stator teeth 211 spliced in a ring shape, and the top and bottom ends of each stator tooth 211 are plugged with a coil skeleton 212. Through the arrangement of the above-mentioned stator teeth, the stator can be spliced, which is convenient for replacing and maintaining a damaged stator or coil, and is convenient for production and cost saving. The arrangement of the coil skeleton can increase the protection of the stator, reduce the loss of the coil to the stator, and facilitate the glue sealing and fixing of the upper and lower cover shells by cooperating with the structure of the upper and lower cover shells; each stator tooth 211 and every two coil skeletons 212 are wound with a coil winding, and the wire ends of the coil winding are all centrally led out of the glue filling port 231 through the circuit board. Through the above-mentioned arrangement of the coil winding, the line can be sorted to avoid the windings interfering with each other to increase the circuit burden, thereby improving the current output effect.
[0021] The upper end of the stator tooth is connected to a coil frame through structural cooperation, and the lower end of the stator tooth is also connected to a coil frame through structural cooperation. The coil is wound on the coil frame and the stator tooth. The wire ends of the coil winding on each stator tooth are fixed on the circuit board, and then the lead wires on the circuit board are led out of the glue filling port.
[0022] like Figure 3 As shown, a strip groove 213 is provided on the outer side of each stator tooth 211. Through the provision of the above-mentioned strip groove, when the stator and the housing are interference-fitted, the deformation capacity of the stator is increased to avoid damage to the stator due to excessive extrusion of the stator; the card grooves and the card parts on the side walls of two adjacent stator teeth are plugged into each other to be connected, thereby forming a complete stator, and multiple strip grooves can be provided as needed.
