Description

Technical Field

[0001] The utility model relates to the technical field of drive modules, in particular to a linear drive module in a dust-free environment. Background Art

[0002] Linear motion modules are widely used in industrial automation equipment, especially in low-dust dust-free workshops. The existing modules have the following defects: simple structure, poor dust-proof effect, and easy to pollute the environment in the workshop. However, the existing linear modules are usually not sealed, so they are easily polluted by dust, which makes the debris in the working environment enter the guide rail and affect the movement of the linear module. In addition, it is not easy to install and maintain, which greatly shortens the service life of the linear module. In view of this, researchers in this field have designed a dust-free environment linear drive module. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a dust-free environment linear drive module with good sealing performance, so as to prevent external dust and other debris from entering the drive module and affecting the operation of the drive module.

[0004] The technical solution of the utility model is: a dust-free environment linear drive module, comprising a linear movable seat and a slide table slidably arranged on the linear movable seat, the upper surface of the linear slide groove is provided with an installation cavity through a groove, the linear movable seat has a plurality of stators linearly arranged at the bottom of the installation cavity, a mover is correspondingly arranged above the stator, an air gap exists between the stator and the mover, the slide table is fixedly connected to the mover, a magnetic strip is fixedly connected to the upper surface of the linear movable seat on both sides of the groove, a dustproof steel belt is arranged on the linear movable seat above the installation cavity, both ends of the dustproof steel belt are fixed on the linear movable seat, the dustproof steel belt is magnetically connected to the magnetic strip, the dustproof steel belt runs through the slide table, and trachea seats are arranged at both ends of the linear movable seat, and the trachea seats are communicated with the installation cavity.

[0005] It can be seen from the above scheme that the mover realizes linear motion on the stator, and the dust-proof steel belt is realized by magnetic connection with the magnetic strip to seal the installation cavity, thereby realizing dust prevention inside the linear moving seat, and the air pipe seat is used to fill gas into the installation cavity in the linear moving seat to prevent dust from entering the linear moving seat.

[0006] The stator is a rectangular magnet, and the mover is provided with a coil winding. It can be seen that the coil winding is driven on the stator to drive the slide to perform linear motion when powered on.

[0007] The slide includes a slide base plate, a slide seat arranged on the slide base plate, and a slide cover plate arranged on the slide seat. The bottom of the slide base plate is fixedly connected to the stator. The upper surface of the slide seat is inclined downward from the middle to both sides to form guide slopes. Wear-resistant sheets are arranged on the two groups of guide slopes. The dustproof steel sheet is in contact with the upper surface of the wear-resistant sheet.

[0008] Guide rails are arranged on both sides of the stator, and sliders are arranged on the guide rails. The bottom of the slide base is fixedly connected to the sliders. It can be seen that the sliders are slidably matched with the sliders to guide the linear motion of the mover on the stator, thereby ensuring the stability of the linear motion of the linear drive module.

[0009] The first oil injection hole and the second oil injection hole are respectively arranged on both sides of the slide seat, and the upper surface of the slide seat is provided with an oil injection groove, through which the first oil injection hole and the second oil injection hole are connected. It can be seen that the oil injection groove is used in combination with the first oil injection hole and the second oil injection hole to realize the oil injection maintenance of the linear drive module.

[0010] One side of the linear motion seat is provided with three groups of slot-type photoelectric sensors, and the other side is provided with a position detection member. It can be seen that the photoelectric sensors and the position detection member are both used for the position of the slide on the linear motion seat.

[0011] The position detection element is a magnetic scale or a grating scale. It can be seen that the grating scale and the magnetic scale are both position detection elements used to measure the position information of the linear motor. BRIEF DESCRIPTION OF THE DRAWINGS
