Description

Technical Field

[0001] The utility model relates to the field of motion controllers, and more specifically, to a moisture-proof structure for a motion controller. Background Art

[0002] The motion controller is a controller specially used to control the operation mode of the motor, and is installed with the motor. When the motor is used in some relatively humid environments, the motion controller may be damp, causing it to not work properly. At present, desiccant is generally used to prevent moisture from entering the motion controller. If the desiccant is placed directly on the motion controller housing, the desiccant will be completely exposed to the outside air and will soon be filled with moisture and become ineffective. It is also not realistic to set the desiccant inside the motion controller, as the motion controller itself is very compact.

[0003] In order to solve the moisture-proof problem of motion controllers, the utility model patent with the authorization announcement number CN 213783825 U provides a moisture-proof motion controller, which is provided with an additional shell, the motion controller is arranged in the shell, and a drying material is arranged in the shell to dry the motion controller. In order to facilitate the replacement of the drying material, a cover plate and a driving structure for opening and closing the cover plate are arranged at the upper end, resulting in the above-mentioned moisture-proof motion controller having a complex structure, and the shell is much larger than the volume of the motion controller, resulting in a large space occupied during installation.

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0028] It should be noted that, in the description of the present invention, the terms "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description. They 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, and therefore cannot be understood as a limitation on the present invention.

[0029] Figure 1-Figure 2 A moisture-proof structure for a motion controller provided in an embodiment of the utility model comprises:

[0030] The housing 1 has an open end and is detachably connected to a baffle 2, wherein the baffle 2 is provided with a threading hole 3;

[0031] A base 4, which is arranged on the bottom wall of the housing 1, and an upper end of which is provided with a mounting groove 5 corresponding to the motion controller;

[0032] A ventilated drying box, wherein an air inlet matching the ventilated drying box 7 is provided on the side wall of the housing 1, and the ventilated drying box is detachably arranged at the air inlet;

[0033] The fan 6 is provided at the upper end of the housing 1 with a mounting hole matching the fan 6, and the fan 6 is embedded in the mounting hole.

[0034] In this embodiment, when installing the motion controller, first remove the baffle 2 on the housing 1, set the motion controller on the base 4 inside the housing 1, then pass the various connecting wires that need to be connected to the motion controller through the threading holes 3 on the threading plate, and then install the baffle 2 at one end of the housing 1. The threading hole 3 is large in diameter to facilitate the end connector of the connecting wire to pass through. After installing the baffle 2, the threading hole 3 can be filled with sealant to seal the threading hole 3 to ensure that the baffle 2 can completely seal the opening at one end of the housing 1. During the operation of the motion controller, the fan 6 discharges the air inside the housing 1 to the outside, and the external air enters through the air inlet. After passing through the breathable drying box, the water vapor in the air is absorbed by the breathable drying box, so that the air entering the housing 1 is dry. The fan 6 accelerates the circulation of the air inside the housing 1, which can have a heat dissipation effect on the motion controller. According to actual conditions, when the temperature and humidity of the use environment are not too high, the fan 6 can work intermittently. The detachable connection between the breathable drying box and the housing 1 is convenient for maintenance and replacement of the breathable drying box.

[0035] Preferably, as another embodiment of the present utility model, Figure 2 and Figure 3 As shown, the air-permeable drying box comprises:

[0036] A box body 7, one end of which is open and the other end of which is evenly distributed with a plurality of air holes, the box body 7 passes through the air inlet and fits with the inner wall thereof;

[0037] A mesh plate 8, which is detachably arranged at the air inlet and connected to an opening at one end of the box body 7;

[0038] A desiccant 9 is filled in the box body 7 .

[0039] In this embodiment, the mesh plate 8 is detachably connected to the shell 1, and the box body 7 is detachably connected to the mesh plate 8, so that after the box body 7 is removed from the air inlet of the shell 1, the box body 7 can be opened to replace the desiccant 9 inside. The desiccant 9 is water-absorbing resin particles. The gaps between the water-absorbing resin particles are used to allow air to pass through the desiccant 9, and when passing through the desiccant 9, the water vapor inside is absorbed by the water-absorbing resin particles. Since the volume of the water-absorbing resin particles increases after absorbing water, the staff needs to regularly check the water-absorbing resin particles in the box body 7 to avoid the water-absorbing resin particles from increasing in volume due to long-term use, resulting in a decrease in the gaps between the water-absorbing resin particles, which affects the air permeability of the desiccant 9. Specifically, as one of the specific connection methods, such as Figure 3As shown, the connection between the mesh plate 8, the box body 7 and the mesh plate 8 can adopt the following structure: a plurality of threaded rods 10 are arranged at intervals on the outer side of the air inlet, an outer flange is arranged at one end of the box body 7, a positioning groove matching the outer flange is arranged on the mesh plate 8, and a plurality of through holes corresponding to and equal in number to the threaded rods 10 are arranged on the outer flange and the mesh plate 8, the threaded rods 10 pass through the corresponding through holes, and nuts 11 are threadedly installed thereon, and the box body 7, the mesh plate 8 and the shell 1 can be connected and fixed by tightening the nuts 11.

[0040] Preferably, as another embodiment of the utility model, it also includes:

[0041] A one-way valve 12 is disposed at the upper end of the housing 1 and communicated with the mounting hole.

[0042] In this embodiment, a one-way valve 12 is provided at the upper end of the mounting hole, so that at the mounting hole, only the air inside the shell 1 can flow outward, and the air outside the shell 1 cannot enter the shell 1. When the fan 6 is not working, the gas outside the shell 1 cannot enter the shell 1 through the mounting hole.

[0043] Preferably, as another embodiment of the utility model, it also includes:

[0044] An air humidity sensor, which is arranged in the housing 1;

[0045] A controller is communicated with the air humidity sensor and the fan 6 respectively.

[0046] In this embodiment, the air humidity inside the shell 1 is detected by an air humidity sensor, and the humidity data of the air in the shell 1 is sent to the controller in real time. The humidity alarm threshold is set in the controller in advance. When the air humidity in the shell 1 is lower than the humidity alarm threshold, the controller controls the fan 6 not to work; when the air humidity in the shell 1 reaches or exceeds the humidity alarm threshold, the controller controls the fan 6 to start working.

[0047] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation scheme. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented.
