[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used herein in the description of the present utility model are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0019] The following further details the embodiments of the present utility model in conjunction with the drawings:

[0020] Since there are already various conveying devices on the market at present, they meet the basic requirements of material transmission to a certain extent. However, with the continuous development and upgrading of industrial production, the requirements for conveying devices are also increasing day by day, especially the requirements for their volume, weight, installation convenience, and dust-proof performance are more urgent. Therefore, this utility model designs such a motion platform, such as Figure 1 shown, which includes a base 1, 13 groups of synchronous belts and sliders 2 located on the base 1, and also includes a dust-proof cover 3. Slots 4 are provided at both opposite ends of the slider 2. The two side walls of the dust-proof cover 3 are respectively located in the slots 4. The dust-proof cover 3 covers the base 1. The slider 2 can slide on the dust-proof cover 3. That is, when the slider 2 slides to different positions through the slots 4, the internal 13 groups of synchronous belts and other structures are blocked by the dust-proof cover 3. That is, the dust-proof cover 3 effectively isolates the influence of the external environment on the motion mechanism, reduces friction and wear caused by dust, impurities, etc., thereby improving the motion accuracy and stability; secondly, the dust-proof cover 3 reduces the wear and failure rate of components such as the synchronous belt 13 and the slider 2, and extends the service life of the entire motion platform; in addition, this kind of motion structure has advantages in terms of volume, weight, and installation convenience.

[0021] Specifically, two groups of optical axes 5 are also provided on the base 1. The optical axes 5 are arranged along the length of the base 1. Two limiting walls 6 are provided on the upper surface of the base 1. Embedding grooves 7 for installing the optical axes 5 are provided on the opposite surfaces of the two limiting walls 6. Part of the optical axes 5 are exposed outside the embedding grooves 7. Two groups or four groups of sliding parts are also provided on the slider 2. When there are two groups, each optical axis 5 is adapted to a group of sliding parts. When there are four groups, each optical axis 5 is adapted to two groups of sliding parts. The sliding parts include eccentric wheels 8 and bearings 9. The eccentric wheels 8 are connected to the bottom of the slider 2. The bearings 9 are located below the eccentric wheels 8. There is a gasket between the bearings 9 and the eccentric wheels 8, and the bearings 9 and the eccentric wheels 8 are coaxially connected. When the slider 2 is slidably connected to the optical axis 5, the outer surface of the bearing 9 contacts the optical axis 5. When the slider 2 slides, the eccentric wheel 8 therein can ensure the rotation of the bearing 9 to make the sliding process stable.

[0022] In addition, in order to improve the stability of the slider 2, a U-shaped groove matching with the optical axis 5 is provided on the outer surface of the bearing 9. Part of the optical axis 5 exposed outside the embedding groove 7 is stuck in the U-shaped groove. When the bearing 9 rotates to make the slider 2 slide, it can prevent the slider 2 from disengaging from the optical axis 5.

[0023] A photoelectric trigger board 10 is also provided on the slider 2, and a photoelectric wire 11 matching with the photoelectric trigger board 10 is provided on the base 1. The current purpose of the photoelectric trigger board 10 and the photoelectric wire 11 is mainly to prevent the sliding distance of the slider 2 from exceeding the limit, so as to prevent the slider 2 from hitting both sides, and can also prevent the motor from still outputting after the slider 2 slides to the limit position, protecting the motor to the greatest extent.

[0024] In addition, anti-collision silica gels 12 are also provided on the base 1. When the sliding speed of the slider 2 is too fast or it reaches the limit position, the anti-collision silica gels 12 on both sides of the base 1 can prevent the slider 2 from hitting and play a buffering role.

[0025] The 13 groups of synchronous belts include synchronous belts 13, motors, synchronous pulleys and motor fixing seats. At the connection of both ends of the synchronous belt 13, there are synchronous belt 13 fixing plates for connecting both ends. The slider 2 is also provided with a synchronous belt 13 tooth pressing plate connected to the synchronous belt 13. The main purpose of setting the synchronous belt 13 fixing plate and the synchronous belt 13 tooth pressing plate at the connection of both ends of the synchronous belt 13 is to ensure the stability of the connection of the synchronous belt 13 and the accuracy of transmission. The synchronous belt 13 fixing plate is used to firmly connect both ends of the synchronous belt 13 together to prevent it from falling off or loosening during the transmission process. The synchronous belt 13 tooth pressing plate increases the friction between the teeth and the belt by pressing the tooth-shaped part of the synchronous belt 13, improving the stability and efficiency of transmission.

[0026] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art in this technical field, several improvements and refinements made without departing from the principle of the present invention should also be regarded as within the protection scope of the present invention.
