Description

Technical Field

[0001] This utility model relates to the technical field of motors, and in particular to a linear motor. Background Technology

[0002] A linear motor is a transmission device that directly converts electrical energy into linear motion mechanical energy without any intermediate conversion mechanism. It can be viewed as a rotary motor cut radially and unfolded into a plane. Linear motors have gradually replaced ball screws as the mainstream for driving linear motion.

[0003] A search revealed Chinese patent CN 222068227 U, which discloses a linear motor comprising a stator slide rail and a mover slidably fitted onto the stator slide rail. The linear motor is connected to an oil box with an oil reservoir. An oil guide component is provided within the oil reservoir. The oil guide component has a buffer surface and an oil inlet extending from the buffer surface to the opposite side. The oil guide component is connected to a lubrication unit for lubricating the linear motor. However, because the stator and mover attract each other, a downward pulling force is generated. Thus, the moving base must bear not only the external load but also the mutual attraction between the stator and mover, resulting in a reduction in the load capacity of the module. Utility Model Content

[0004] The purpose of this invention is to provide a linear motor that supports and pulls the mover through support rollers and a vertical plate, guiding the movement direction of the mover and providing support, thereby effectively improving the load capacity of the module. When the mover moves, the guide groove slides on the guide protrusion. When the mover abuts against the mounting guide groove, it can reduce the load on the guide protrusions on both sides and improve the service life. When the mover is isolated from the mounting guide groove, it can reduce friction and make the operation more stable.

[0005] The technical solution adopted by this utility model is as follows: A linear motor includes a housing, a stator, a mover, two mounting guide slots, two vertical plates, multiple support rollers, two first guide wheels, two second guide wheels, a mounting plate, a moving component, a guiding component, and a sealing assembly. The housing has a mounting slot inside, the stator is located in the mounting slot, the mover slides with the stator, the moving component and the guiding component are installed between the mover and the mounting slot of the housing, and the sealing assembly is installed inside the housing.

[0006] The moving part includes two mounting guide slots, which are respectively installed at the front and rear ends of the upper part of the mounting slot. Two vertical plates are fixedly installed at the front and rear ends of the upper part of the mover. Multiple support rollers are rotatably installed on the vertical plates, and the support rollers roll within the mounting guide slots.

[0007] The guide component includes guide ribs, two guide ribs are respectively installed on the side walls of the front and rear mounting guide grooves, and the mover is provided with guide grooves that match the guide ribs;

[0008] The enclosed assembly includes a tape reel and a connecting plate. A rotating cavity is provided at the bottom of the housing. Limiting grooves are provided at both ends of the upper part of the mounting groove. The tape reel is located in the rotating cavity. The left and right ends of the tape reel slide in the limiting grooves. A connecting plate is installed on the mover. The connecting plate is connected to the left and right ends of the tape reel by screws.

[0009] Furthermore, two first guide wheels are rotatably mounted on the upper left and right sides inside the housing, and two second guide wheels are rotatably mounted on the lower left and right sides inside the housing.

[0010] Furthermore, a mounting plate is installed on the top of the mover, and the mounting plate has multiple mounting holes.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. By supporting the moving part with support rollers and vertical plates, the moving part is guided in the direction of movement and supported, which can effectively improve the load capacity of the module.

[0013] 2. When the mover moves, the guide groove slides on the guide protrusion. When the mover abuts against the mounting guide groove, it can reduce the load on the guide protrusions on both sides and improve the service life. When the mover is isolated from the mounting guide groove, it can reduce the friction and make the operation more stable.

[0014] 3. When the mover moves, it is driven to rotate by the conveyor belt. The conveyor belt can seal the mounting slot to prevent dust and impurities from affecting the normal operation of the linear motor. Attached Figure Description
