Description

Technical Field

[0001] The utility model relates to the technical field of linear motor modules, in particular to a long-stroke linear motor module. Background Art

[0002] When current passes through the coil on the stator of a long-stroke linear motor module, a magnetic field is generated. This magnetic field interacts with the permanent magnet on the mover to generate a force perpendicular to the direction of the magnetic field. This force pushes the mover (slider) to move linearly along the guide rail. Due to the direct action of the magnetic force, the linear motor module can achieve extremely high acceleration and deceleration, as well as precise positioning and repeatability.

[0003] Existing devices generate dust on the running track. When too much dust accumulates, it will hinder the operation of the linear motor. Manual cleaning by workers not only takes a lot of time, but is also inconvenient and cannot be carried out efficiently. Utility Model Content

[0004] The utility model discloses a long-stroke linear motor module, which aims to solve the technical problem that the long-stroke linear motor module generates dust during operation. When the dust accumulates to a certain extent, it will hinder the operation of the device and cause loss of the device. At the same time, manual cleaning will consume a lot of time.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A long-stroke linear motor module comprises a long-stroke linear motor housing, and cleaning mechanisms are provided on both sides of the long-stroke linear motor housing. The cleaning mechanism comprises a double-headed motor, and fixed frames are provided on both sides of the double-headed motor.

[0007] By providing a long-stroke linear motor housing and a cleaning mechanism, when the long-stroke linear motor module is working, the double-headed motor is started to drive the rotating threaded rod to rotate, and during the rotation of the rotating threaded rod, the sliding seat located on the outside reciprocates according to the movement trajectory of the sliding frame. At the same time, the cleaning roller on the support rod fixedly connected to the sliding seat cleans the inside of the limiting track under the reciprocating motion of the sliding seat. During the process, the cleaning mechanism effectively cleans the inside of the limiting track, keeps the inside of the track clean, and avoids excessive dust accumulation inside the track that hinders the movement of the sliding frame and causes machine damage.

[0008] In a preferred embodiment, a load-bearing device is provided above the long-stroke linear motor housing, the load-bearing device includes a storage plate, and the bottom ends of the storage plates are connected to symmetrical fixed rods through threads, both ends of the fixed rods are movably connected to multiple movable rods, and the ends of the multiple movable rods away from the fixed rods are movably connected to multiple connecting seats, the side of the connecting seat away from the movable rod is fixedly connected to multiple telescopic rods, the side of the connecting seat away from the movable rod is fixedly connected to multiple telescopic springs, and the telescopic springs are all located on the outside of the telescopic rod, and a symmetrical connecting shaft is fixedly connected between the two telescopic rods, the two sides of the symmetrical connecting shaft are fixedly connected to the symmetrical telescopic springs, and the bottom ends of the connecting shafts are fixedly connected to groove seats, the top ends of the groove seats are movably connected to the symmetrical connecting seats, and the bottom ends of the groove seats are movably connected to movable wheels.

[0009] By providing a load-bearing device, when the long-stroke linear motor module is running, the material is placed on the storage plate, and the weight of the material drives the movable rod to slide on the inner side of the groove seat, and then the telescopic rod and the telescopic spring are used for buffering. The connecting shaft fixes the position of the groove seat. When the material leaves, the buffer spring and the elastic effect of the spring restore the movable rod to its original state, and the movable wheel assists the reciprocating action of the sliding frame. During the process, the load-bearing device not only increases the weight of the transportation, but also prevents the long-stroke linear motor module from being damaged and deformed due to excessive weight of the material.

[0010] In a preferred solution, both ends of the long-stroke linear motor housing are fixedly connected to sealing covers, both sides of the long-stroke linear motor housing are fixedly connected to limiting rails, and the inner top ends of the limiting rails are fixedly connected to linear guide rails, the top ends of the linear guide rails are in contact with the cleaning rollers, the top ends of the linear guide rails are movably connected to sliding frames, the double-headed motors are located above the sliding frames, and the front sides of the sliding frames are fixedly connected to support frames, and the top ends of the support frames are fixedly connected to the bottom ends of the storage plates.

[0011] By setting a limited position track, a sliding frame, a support frame, a linear guide rail and a sealing cover, the sealing cover seals the long-stroke linear motor housing to prevent dust from entering the interior of the long-stroke linear motor housing. The support frame fixes the position of the load-bearing equipment, allowing the load-bearing equipment to perform reciprocating motion, while the sliding frame slides on the linear guide rail.

[0012] From the above, it can be seen that the long-stroke linear motor module provided by the utility model has a cleaning mechanism during the process, which effectively cleans the inside of the limit track, keeps the inside of the track clean, and avoids excessive dust accumulation inside the track that hinders the movement of the sliding frame and causes machine loss.
