Description

Technical Field

[0001] This utility model belongs to the field of motor installation technology, specifically relating to a silicon steel sheet sealing device for motors. Background Technology

[0002] Silicon steel sheets are a soft magnetic alloy of silicon and iron with extremely low carbon content. Adding silicon can increase the resistivity and maximum permeability of iron, and reduce coercivity, core loss (iron loss), and magnetic aging. It is mainly used to make the cores of various transformers, motors, and generators.

[0003] In the field of motor manufacturing, silicon steel sheets are the core material of the iron core, and their sealing process directly affects the magnetic properties and structural stability of the motor. Traditional silicon steel sheet sealing devices usually have certain technical defects. For example, the adsorption components (such as suction cups) mostly adopt a fixed structure. When a single or partial suction cup fails to airtightness or the pipeline is blocked, the entire machine needs to be shut down for maintenance. After the maintenance is completed, the equipment parameters need to be readjusted, resulting in the interruption of the production process. Utility Model Content

[0004] The purpose of this utility model is to provide a silicon steel sheet sealing device for motors, in order to solve the problem mentioned in the background art that the adsorption components (such as suction cups) mostly adopt a fixed structure. When a single or part of the suction cups fails to airtightness or the pipeline is blocked, the whole machine needs to be shut down for maintenance. After the maintenance is completed, the equipment parameters need to be readjusted, which leads to the interruption of the production process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a silicon steel sheet sealing device for motors, comprising a worktable, a limiting sleeve one and a limiting sleeve two, wherein the surface of the worktable is provided with grooves that match the limiting sleeve one and the limiting sleeve two, and cylinder one and cylinder two are respectively installed on the bottom wall of the inner cavity of the worktable, and a push plate and a heating plate one are respectively fixed at the output ends of cylinder one and cylinder two, and two mounting slots are provided on the surface of the worktable, wherein a linear reciprocating motor is installed in the mounting slots, and a fixed box is installed at the drive end of the linear reciprocating motor; A mounting plate is movably connected between the two fixed boxes. Mounting bracket one and mounting bracket two are respectively mounted on the bottom of the mounting plate. A roller brush is rotatably connected inside mounting bracket one. A stepper motor is mounted on one outer wall of mounting bracket two, and an air pipe is fixed to the output end of the stepper motor. Multiple suction cups are mounted on the upper and lower outer walls of the air pipe.

[0006] In a further embodiment, a drive motor is mounted on the surface of the fixed box, a guide screw is fixed to the output end of the drive motor, and a guide block that is fixedly connected to the mounting plate is threaded onto the outer wall of the guide screw.

[0007] In a further embodiment, a liquid storage tank is mounted on the surface of the mounting plate, and a plurality of guide tubes extending into the mounting frame are mounted on the bottom of the liquid storage tank.

[0008] In a further embodiment, a cylinder three is mounted on the surface of the mounting plate, and a heating plate two is mounted on the output end of the cylinder three.

[0009] In a further embodiment, a negative pressure pump is mounted on the surface of the mounting plate, and a connecting pipe extending into the vent pipe is mounted on the suction end of the negative pressure pump, and the connecting pipe is rotatably connected to the vent pipe through a bearing.

[0010] In a further embodiment, the top of the liquid storage tank is provided with a feed hole and a vent hole, and a feed pipe and a vent pipe are respectively installed in the feed hole and the vent hole.

[0011] The technical effects and advantages of this utility model are as follows: This silicon steel sheet sealing device for motors is designed to drive the air pipe to rotate via a stepper motor. When the suction cup above or below the air pipe malfunctions, the intact suction cup on the other side can be rotated to the working position immediately without stopping the machine for maintenance, significantly shortening maintenance time. The liquid storage tank is linked with the roller brush through the guide tube to achieve uniform application of glue. Heating plate one and heating plate two work together to hot-press and cure the silicon steel sheet immediately after sealing, avoiding the glue layer displacement caused by transportation in the traditional process. The hot pressing temperature and pressure can be precisely controlled, which effectively improves the bonding strength of the silicon steel sheet stack. Cylinder 1 and Cylinder 2 work together with Limiting Sleeve 1 and Limiting Sleeve 2 to achieve automatic feeding and positioning of silicon steel sheets. A linear reciprocating motor drives the sealing assembly to reciprocate, forming a "adsorption-transfer-coating-hot pressing" assembly line operation mode. This design improves processing efficiency while reducing manual intervention and labor intensity. This silicon steel sheet sealing device for motors can not only improve processing efficiency, but also reduce downtime maintenance time. Attached Figure Description

The output ends of the first cylinder 4 and the second cylinder 6 are respectively fixed with a push plate 5 and a heating plate 7. The push plate 5 and the heating plate 7 are movably connected to the first limiting sleeve 2 and the second limiting sleeve 3. An electric heating tube is installed in the heating plate 7. The surface of the worktable 1 is provided with two mounting slots. A linear reciprocating motor 8 is installed in the mounting slots, and a fixed box 9 is installed at the drive end of the linear reciprocating motor 8.

The bottom of the guide screw 11 is rotatably connected to the bottom plate of the fixed box 9 through a bearing, thereby ensuring the stability of the guide screw 11 when rotating. A guide block 12 is threadedly connected to the outer wall of the guide screw 11 and fixedly connected to the mounting plate 13. Guide grooves for the guide block 12 to move are opened on the opposite surfaces of the two fixed boxes 9. When the drive motor 10 drives the guide screw 11 to rotate, it can restrict the movement path of the guide block 12 and the mounting plate 13, ensuring that the mounting plate 13 moves vertically and stably between the two fixed boxes 9. A liquid storage tank 14 is mounted on the surface of the mounting plate 13. The top of the liquid storage tank 14 is provided with a feed hole and a vent hole. A feed pipe and a vent pipe are installed in the feed hole and the vent hole, respectively. The vent pipe is set to ensure the air pressure balance in the liquid storage tank 14. The liquid storage tank 14 stores glue. A mounting bracket 15 and a mounting bracket 21 are mounted on the bottom of the mounting plate 13. A roller brush 17 is rotatably connected in the mounting bracket 15. Multiple guide pipes 16 extending into the mounting bracket 15 are installed at the bottom of the liquid storage tank 14.

[0020] Working principle: In use, the silicon steel sheet sealing device for motors places the silicon steel sheet to be processed inside the limiting sleeve 2. The linear reciprocating motor 8 drives the fixed box 9 to move, so that the suction cup 24 moves above the limiting sleeve 2. The drive motor 10 drives the guide screw 11 to rotate, which drives the mounting plate 13 to descend through the guide block 12. At the same time, the solenoid valve on the suction cup 24 below the vent pipe 23 is opened, and the negative pressure pump 20 is started. The silicon steel sheet is adsorbed by the suction cup 24. The linear reciprocating motor 8 drives the fixed box 9 to continue to move, so that the suction cup 24 moves above the limiting sleeve 3. The negative pressure pump 20 is turned off, so that the silicon steel sheet falls into the limiting sleeve 3. The adhesive in the storage tank 14 is evenly applied to the roller brush 17 through the guide tube 16. The linear motor 8 drives the fixing box 9 to reset, so that the suction cup 24 moves above the limiting sleeve 2. During the movement of the fixing box 9, the adhesive on the roller brush 17 is evenly applied to the surface of the silicon steel sheet. The above steps are repeated. At the same time, the cylinder 4 and the cylinder 6 cooperate with each other to keep the upper surface of the silicon steel sheet in the limiting sleeve 2 and the limiting sleeve 3 at the same level. After the sealing is completed, the cylinder 18 drives the heating plate 19 to descend and press it against the surface of the sealed silicon steel sheet. At the same time, the heating plate 7 works to heat the silicon steel sheet, so that the silicon steel sheet is tightly bonded together. After the hot pressing is completed, the cylinder 18 resets and the cylinder 6 starts to push the silicon steel sheet out of the limiting sleeve 3.
