AI Technical Summary
When the current is unstable, the linear motor moves faster. After a power outage, the moving worktable is demagnetized and moves freely, which may damage the device or cause property damage.
A limiting component is adopted, including an electromagnet and a limiting rod. The position of the limiting rod is controlled by energizing and de-energizing the electromagnet, which restricts the movement of the slide and ensures that the slide is limited when the power is off, and can move freely when the power is on.
This effectively prevents the slide from moving freely when the power is off, protecting the integrity of the device and avoiding property damage.

[0018] The technical scheme of the utility model will be described clearly and completely in combination with the drawings, and obviously, the described embodiment is a part of the embodiment of the utility model, instead of all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by the ordinary skill in the art without making the creative labor all belong to the scope of protection of the utility model.
[0019] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "vertical", "horizontal", "inside", "outside", "front", "back" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.
[0020] like Figures 1 to 4 As shown, the present invention proposes an automatic power-off linear module, comprising a linear module body 110 and a slide 120. The linear module body 110 has a guide portion 111, and the slide 120 is slidably connected to the guide portion 111. The sliding connection between the slide 120 and the guide portion 111 has a cavity, in which a limit assembly is disposed. The limit assembly is used to limit the movement of the slide 120 according to the operating state of the linear module. The slide 120 is slidably connected to the guide portion 111 via a sliding portion at its bottom.
[0021] Typically, the linear module is controlled by an external controller. When the controller detects that the current is unstable, it will directly cut off the switch that supplies power to the linear module to stop the linear module from running and achieve automatic power off. Furthermore, in order to prevent the slide 120 from moving freely, the movement of the slide 120 will be restricted by the limit assembly when the linear module is powered off.
[0022] Specifically, the limiting assembly includes an electromagnet 121, a hinge seat 122, a limiting rod 123, and a limiting bar 112. The electromagnet 121 is arranged in the slide seat 120, the limiting rod 123 is rotatably installed in the cavity through the hinge seat 122, and the limiting bar 112 is arranged along the length direction of the guide part 111, and a plurality of limiting grooves 113 are evenly arranged in the length direction of the limiting bar 112.
[0023] Optionally, the limiting rod 123 is made of magnetic material. When the electromagnet 121 is energized, the limiting rod 123 disengages from the limiting slot 113 to allow the slide 120 to move. When the electromagnet 121 is de-energized, the limiting rod 123 enters the limiting slot 113 under the action of gravity to limit the movement of the slide 120.
[0024] Alternatively, a magnetic piece 124 is embedded in the limiting rod 123. When the electromagnet 121 is energized, the limiting rod 123 is separated from the limiting groove 113 by magnetic attraction with the magnetic piece 124 to allow the slide 120 to move. When the electromagnet 121 is de-energized, the limiting rod 123 enters the limiting groove 113 under the action of gravity to limit the movement of the slide 120.
[0025] The limiting rod 123 is under the action of gravity and enters the limiting groove 113 to limit the movement of the sliding seat 120 in the state of power-off of the electromagnet 121, and the limiting rod 123 is separated from the limiting groove 113 by adsorbing the limiting rod 123 or the magnetic sheet 124 on the limiting rod 123 in the state of power-on of the electromagnet 121, thereby realizing the release of the limiting of the sliding seat 120, so that the sliding seat 120 can freely move.
[0026] The electromagnet 121 is arranged above the cavity. The electromagnet 121 is arranged above the cavity, thereby realizing the adsorption of the limiting rod 123 or the magnetic sheet 124.
[0027] In the description of the utility model, it is necessary to explain that, unless there is definite stipulation and limitation, the term "mounting", "connection", "arrangement" should be understood broadly, for example, can be fixed connection, also can be detachable connection, or integrally connected, can be mechanical connection, can be directly connected, also can be indirectly connected through intermediate medium. For ordinary skilled in the art, according to the specific circumstances, the specific meaning of the above-mentioned terms in the utility model is understood.
