Description

Technical Field

[0001] The present invention relates to the technical field of iron core linear motors, and in particular to an iron core linear motor based on carbon fiber technology. Background Art

[0002] A linear motor is a transmission device that converts electrical energy directly into linear motion without any intermediate conversion mechanism. It can be thought of as a rotary motor cut radially and flattened into a flat surface. Linear motors are also called linear motors, linear motors, linear actuators, and pushrod motors. The most commonly used linear motor types are flat plate, U-slot, and tubular. The coils typically consist of three phases, with brushless commutation achieved using Hall effect elements. Linear motors are often simply described as flattened rotary motors, but the operating principle is the same. The mover is made by compressing the coils together with epoxy; the magnetic track is made by attaching magnets (usually high-energy rare earth magnets) to steel. The motor's mover consists of coil windings, a Hall effect element circuit board, a thermistor (temperature sensor for monitoring temperature), and an electronic interface. In rotary motors, the mover and stator require rotating bearings to support the mover and maintain an air gap between the moving parts. Similarly, linear motors require linear guides to maintain the mover's position within the magnetic field generated by the magnetic track. Just like rotary servo motors have encoders mounted on the shaft to provide position feedback, linear motors require a linear position feedback device—a linear encoder. This directly measures the load's position, improving its accuracy. Linear motors are controlled in the same way as rotary motors. Like brushless rotary motors, there's no mechanical connection between the mover and stator (brushless). Unlike rotary motors, where the mover rotates and the stator remains fixed, linear motor systems can be driven by either magnetic tracks or thrust coils (most positioning system applications use fixed magnetic tracks and thrust coils).

[0003] When the iron-core linear motor is in use, it is impossible to limit the movement of the iron-core linear motor, resulting in the iron-core linear motor being prone to shaking when used for a long time, affecting the normal use of the iron-core linear motor. At the same time, when the iron-core linear motor is usually integrated, the iron-core linear motor cannot be disassembled and repaired when it is damaged, which increases the use cost of the iron-core linear motor. Summary of the Invention

[0004] (1) Technical problems solved

[0005] In view of the deficiencies in the prior art, the present invention provides an iron core linear motor based on carbon fiber technology. When the iron core linear motor slides on the surface of the slide rail, the ball bearings are fitted with the upper surface of the cover plate, so that the ball bearings are affected by the friction force generated by the movement of the iron core linear motor, so that the ball bearings can move inside the load-bearing block. At the same time, the ball bearings are affected by the friction force to drive the swing plate to swing forward with the center of the movable seat to pull the first spring. When the swing plate swings to a certain extent, the baffle plate can block and limit the swing amplitude of the swing plate, so that multiple swing plates can use the rolling of the ball bearings on the surface of the cover plate, which can increase the stability of the iron core linear motor during linear movement. The cover plate is engaged with the linear motor housing so that the cover plate can drive the engaging seat to engage with the engaging plate, and the engaging seat inside the engaging seat is engaged. The rubber sleeve can increase the friction force between the embedding plate and the embedding seat, and at the same time can fill the connection between the embedding plate and the embedding seat, and utilize the sliding of the second connecting block and the embedding plate to push the second connecting plate upward, and the movement of the second connecting plate can drive the limit plate to move. When the limit plate moves to the specified position, the insertion rod can pass through the embedding seat and extend into the interior of the embedding plate. Through the continuous movement of the insertion rod, the sliding rod can be retracted into the interior of the insertion rod to fix the second spring, and the sliding rod can drive the second magnetic block to attract the inner wall of the embedding seat, and the insertion rod can drive the stop block to move, so that the first magnetic block can be attracted to the surface of the limit plate to fix the insertion rod, and the extrusion force of the sliding rod and the suction force of the first magnetic block and the second magnetic block can be used to increase the stability of the cover plate when connected to the linear motor housing.

[0021] 3. When multiple slide rails are in use, the elasticity of the third spring is utilized to form a pulling force between the extrusion plate and the inside of the plug-in plate. When the plug-in plate is engaged with the splicing seat, the extrusion plate can be pushed downward so that the extrusion plate can pull the third spring.
