Description

Linear module with dustproof guiding device

The present invention is a linear transmission component, especially a linear module with a dustproof guiding device.

The linear transmission module is mainly composed of a transmission member, a guiding member, a platform and a casing. The platform is protruded from the outer side of the casing, and the platform is connected with the transmission member and the guiding member. The platform is displaced by the rotating motion of the transmission member, and the platform is guided by the guiding member to make a reciprocating motion of the same path, and the linear transmission module is used for a long time after being used for more foreign objects. In the environment, foreign matter will accumulate in the casing, which will affect the operation of the platform, and will also damage the linear transmission module.
However, in order to prevent the above problems from occurring, as in the Republic of China Announcement No. M351763, it is a new type of dust-proof device that exposes the dust-proof device of the linear drive module. The dust-proof belt is pressed by the roller, but the pressing effect of the roller is not good because it cannot be used. Adjusting the pressing force of the roller on the dust-proof belt, so if there is a poor processing of the size or after the roller is worn after a period of time, there will be a gap between the roller and the dust-proof belt, and the opposite roller also loses the effect of pressing the dust-proof belt, if When the roller is in contact with the dustproof tape, it is necessary to manually trim the size of the fit between the roller and the dustproof tape, which is time consuming and laborious, so the conventional technology still needs to be improved.

In view of the above problems, the main purpose of the present invention is to develop a linear module that reduces the friction between the dustproof tape and the guide and avoids the wear of the dustproof tape.
In order to achieve the above object, the present invention is a linear module with a dustproof guiding device, comprising a housing having a receiving portion; a transmission assembly disposed at the receiving portion and having a movement The body is linearly displaceable relative to the housing; a dustproof module comprising: a housing, an introducer, and a dustproof strap, the guide is disposed on the moving body, and the guide is respectively disposed at two ends There are two guiding portions, two guiding portions of the same end are kept at a distance, and the guiding portion is in contact with the lower surface of the dustproof tape, the outer casing is stacked on the dustproof belt, and the outer casing has At least two guiding portions, the two guiding portions are in contact with the upper surface of the dustproof belt.
Preferably, the cross-sectional width of the two guiding portions at one end of the guiding device and the dustproof tape is H; the width of the dustproof tape is A; H/A = 0.01-0.5.
Preferably, the two ends of the dustproof strap are fixed to both ends of the casing by a pressing block.
By the two guiding portions at one end of the guiding device maintaining a spacing arrangement, the contact area between the guiding portion and the dustproof belt is reduced, and the friction between the two is reduced, in addition to avoiding the dustproof belt from being worn. In addition to scratches on the surface, it can also avoid the problem of cracking that may occur for a long time.

Please refer to the first to fourth figures, which is a first embodiment of the present invention. The present embodiment is a linear module with a dustproof guiding device, which comprises a casing (2) having a capacity. a power supply (1), which is disposed at one end of the housing (2); a transmission assembly disposed on the receiving portion (21) and having a moving body (3) and a guide rail (not shown) and a screw shaft (not shown), the moving body (3) is sleeved on the guide rail and the screw shaft, and the power source (1) drives the screw shaft to rotate the movable body (3) The linear displacement of the housing (2), the moving body (3) is provided with a plurality of screw holes (31); a dustproof module comprising: a housing (5), an introducer (4) a dustproof belt (6) and a pressing block (8), the two ends of the dustproof belt (6) are fixed to the two ends of the casing (2) by the pressing block (8), and the pressing block (8) is The housing (2) is fixed to the housing (2) by a screw (7), and the guiding device (4) is disposed on the moving body (3), and the guiding device (4) is respectively provided with two guiding ends at two ends. lead The portion (41), the two guiding portions (41) at the same end are maintained at a spacing (D), and the guiding portion (41) is in contact with the lower surface of the dustproof belt (6), the outer casing (5) Is stacked on the dustproof tape (6), and the outer casing (5) has at least two guiding portions (52), and the guiding portions (52) are in contact with the upper surface of the dustproof tape (6); The outer casing (5) is provided with a through hole (51) opposite to the screw hole (31) of the moving body (3), and after the screw (7) is inserted through the through hole (51), the screw (7) is further The screw hole (31) is locked to fix the outer casing (5), and the guide (4) can be positioned on the moving body (3) when the outer casing (5) is fixed. In this embodiment, in order to optimize the matching between the dustproof belt (6) and the guide (4), it is recommended that the two guiding portions (41) at one end of the guiding device (4) and the dustproof The cross-section width of the belt (6) is H; the width of the dust-proof belt (6) is A, and H/A = 0.01-0.5.
In view of the above, the "industry availability" of this creation should be unquestionable.
