[0038] Please refer to Figure 1 and Figure 2 In one embodiment of the present application, the present application proposes a driving device (not shown), which includes a driving member (not shown) and a transmission structure 100.

[0039] Among them, the driving member (not shown) can be a motor to provide a rotational driving force. The transmission structure 100 may include a driving wheel 10, a driven wheel 30, a belt 50 and a sliding platform 70. The driving wheel 10 can be connected to the driving member, and then the driving wheel 10 is driven to rotate by the driving member; the driven wheel 30 and the driving wheel 10 are arranged at intervals, the belt 50 is sleeved on the driving wheel 10 and the driven wheel 30, and the sliding platform 70 is connected to the belt 50. At this time, the object to be moved (not shown) (for example: a laser head or other object for emitting laser for laser processing) can be installed on the sliding platform 70, and then the sliding platform 70 is driven when it moves with the belt 50, thereby realizing the driving device (not shown) driving the object to be moved (not shown).

[0040] Please refer to Figure 1 and Figure 2 In one embodiment of the present application, the present application also proposes the above-mentioned transmission structure 100.

[0041] Please refer to Figures 1 to 3 In one embodiment of the present application, the present application further proposes the above-mentioned sliding platform 70, which can be used to connect with the belt 50 and the object to be moved as described above. The belt 50 can be a closed-loop belt (such as Figure 1 50 in the figure), or an open loop belt (such as Figure 2 ). Furthermore, the belt 50 includes a belt body 51 and a plurality of belt teeth 53 provided on one side of the belt body 51. The belt teeth 53 may be provided on the inner side of the belt body 51, or may be provided on the outer side of the belt body 51. At this time, the inner side and the outer side of the belt body 51 are both defined by the state in which the belt 50 is sleeved on the driving wheel 10 and the driven wheel 30. In addition, the sliding platform 70 and the object to be moved may be connected by a screw connection 75 (which may include screws, or may include bolts and nuts), or may be connected by a snap connection or a magnetic connection, etc. The present application does not limit the connection method between the sliding platform 70 and the object to be moved.

[0042] Next, the structure of the sliding platform 70 proposed in this application is explained and illustrated by an embodiment. In an implementation of this application, please refer to Figures 1 to 3 The sliding platform 70 proposed in the present application is provided with a convex tooth portion 731 and a contact portion 711; the number of the convex tooth portions 731 is at least two, and at least two convex tooth portions 731 are configured to engage with the belt teeth 53; the contact portion 711 and the convex tooth portion 731 are arranged at a relative interval, and the contact portion 711 is configured to contact the side of the belt body 51 away from the belt teeth 53.

[0043] The sliding platform 70 may be a plate structure, or a shell structure or a frame structure formed by a combination of multiple columns, etc. The present application does not limit the structural type and shape of the sliding platform 70.

[0044] The number of the convex tooth portions 731 may be two, three or more, and they are arranged in sequence along the first direction, and the first direction may be parallel to the conveying direction of the belt 50. Therefore, when the sliding platform 70 is connected to the belt 50, after the convex tooth portions 731 and the belt teeth 53 of the belt 50 are engaged, the sliding platform 70 and the belt 50 can be relatively limited in the first direction. Wherein, when the belt 50 is a closed-loop belt, each belt tooth 53 of the belt 50 can be engaged between two adjacent convex tooth portions 731. When the belt 50 is an open-loop belt, and the number of the convex tooth portions 731 is two, the two adjacent belt teeth 53 at the head and tail ends of the belt 50 can be engaged together between the two adjacent convex tooth portions 731. Of course, when the number of the convex tooth portions 731 is three or more, the belt teeth 53 on the head and tail ends of the belt 50 can also be engaged between the two adjacent convex tooth portions 731 respectively.

[0045] When the sliding platform 70 is connected to the belt 50, the abutment portion 711 can abut the side of the belt 50 away from the belt teeth 53. At this time, the abutment portion 711 and the convex tooth portion 731 are defined to be arranged at intervals in the second direction, so the abutment portion 711 and the convex tooth portion 731 can form a clamping space, and the abutment of the abutment portion 711 can further achieve relative positioning of the sliding platform 70 and the belt 50 in the second direction, thereby fixing the belt 50 and reducing the possibility of separation of the belt teeth 53 and the convex tooth portion 731 of the belt 50. Among them, the abutment portion 711 can be a strip plate structure, a plurality of sub-plates or a cylindrical structure, so that it can include a flat or curved abutment surface 712 as described below, and then the abutment surface 712 can be used to abut and limit the side of the belt 50 away from the belt teeth 53, so as to achieve "face-to-face" abutment. Of course, the abutment portion 711 can also include a plurality of V-shaped structures or prism structures, etc. At this time, the abutment portion 711 includes an abutment edge, and then the side of the belt 50 away from the belt teeth 53 is abutted and limited by multiple abutment edges to achieve "line and surface" abutment. It can be seen that the present application does not limit the structural type of the abutment portion 711, and the abutment form of the abutment portion 711 and the belt 50. Among them, the belt 50 can be pressed between the abutment portion 711 and the convex tooth portion 731, and the belt 50 can be interference fit with the sliding platform 70 to improve the connection stability.

[0046] When the sliding platform 70 of the technical solution of the present application is connected to the belt 50, since the sliding platform 70 is provided with relatively spaced convex teeth 731 and abutment 711, both the closed-loop belt and the open-loop belt can be a structure including a belt body 51 and belt teeth 53 provided on one side of the belt body 51. Therefore, the closed-loop belt or the open-loop belt can be placed between the convex teeth 731 and the abutment 711, so that the convex teeth 731 and the belt teeth 53 are engaged and limited, and the abutment 711 is used to abut and limit the side of the belt body 51 away from the belt teeth 53, so as to realize the sliding platform 70 and the closed-loop belt (such as Figure 1 as shown) or an open loop belt (as Figure 2 As shown), that is, the sliding platform 70 is compatible with two types of belts 50 for connection and use.

[0047] Please refer to Figure 1 or Figure 2 In one embodiment of the present application, the abutment portion 711 and the convex tooth portion 731 are spaced apart in the second direction, the sliding platform 70 has a center line 70a in the second direction, and the number of the convex tooth portions 731 located on opposite sides of the center line 70a is the same.

[0048] In this embodiment, the number of the convex teeth 731 on both sides of the center line 70a of the sliding platform 70 is set to be the same, so that the belt 50 can be evenly stressed at both ends of the driving wheel 10 and the driven wheel 30, which is conducive to improving the stability of the connection of the belt 50 on the sliding platform 70, so as to improve the stability of the belt 50 transmission. In particular, for an open-loop belt, the stability of the connection between the head and tail ends of the belt 50 and the sliding platform 70 can be improved, thereby improving the uniformity and stability of the overall stress of the belt 50. Of course, it should be noted that the present application is not limited to this. In other embodiments, the number of the convex teeth 731 on both sides of the center line 70a of the sliding platform 70 can also be different, and it can even be that the convex teeth 731 is only set on one side of the center line 70a of the sliding platform 70. At this time, the docking position of the head and tail ends of the open-loop belt also deviates from the side of the center line 70a of the sliding platform 70 accordingly, so as to be meshed and connected with the convex teeth 731 eccentrically on the side of the center line 70a of the sliding platform 70.

[0049] Please refer to Figure 1 or Figure 2 In one embodiment of the present application, the number of the protruding tooth portions 731 located on opposite sides of the center line 70a is at least two.

[0050] In this embodiment, the number of the convex teeth 731 located on both sides of the center line 70a of the sliding platform 70 is set to at least two, which can increase the meshing point between the belt 50 and the sliding platform 70, so as to further improve the stability of the overall connection of the belt 50 on the sliding platform 70. Among them, the number of the convex teeth 731 located on both sides of the center line 70a of the sliding platform 70 can be two, three or more. Of course, the present application is not limited to this. In other embodiments, the number of the convex teeth 731 located on both sides of the center line 70a of the sliding platform 70 can be set to one.

[0051] Please refer to Figures 1 to 3 In one embodiment of the present application, the abutting portion 711 includes an abutting surface 712 , the abutting surface 712 and the convex tooth portion 731 are arranged relatively spaced apart, and the abutting surface 712 is configured to abut against a side of the belt body 51 away from the belt teeth 53 .

[0052] In this embodiment, the abutting portion 711 is configured to abut the belt 50 through the abutting surface 712, which can facilitate the abutting of the abutting portion 711 and the belt 50, and increase the contact area between the two, thereby facilitating the abutting and limiting effect of the abutting portion 711 on the belt 50. Among them, the abutting surface 712 can be a plane. At this time, the abutting surface 712 can be parallel to the belt 50, thereby facilitating further improving the abutting effect of the abutting surface 712 and the belt 50, and increasing the contact area between the two. At the same time, the abutting portion 711 can be configured as a plate structure, so that the shape and structure of the abutting portion 711 are relatively simple, thereby facilitating improving the convenience of manufacturing the abutting portion 711. For example: the abutting portion 711 can be configured as a strip-shaped flat plate structure, or include a plurality of sub-plate bodies spaced apart in the first direction, and the abutting surface 712 can include sub-contact surfaces, each of which can be arranged on a sub-plate body. Of course, in some embodiments, the abutting surface 712 can also be an arc surface.

[0053] Please refer to Figures 1 to 3 In one embodiment of the present application, at least two convex tooth portions 731 are arranged sequentially in the first direction, and the abutment portion 711 and the convex tooth portion 731 are arranged at intervals in the second direction; the abutment portion 712 and the convex tooth portion 731 have equal length dimensions in the third direction, and the third direction, the second direction and the first direction intersect each other.

[0054] In this embodiment, the length dimensions of the abutting surface 712 and the convex tooth portion 731 in the third direction are set to be equal, so that the outer side and the inner side of the belt 50 can be uniformly contacted and limited, which is conducive to further improving the force stability of the belt 50 and improving the stability of the connection between the belt 50 and the sliding platform 70. Of course, the present application is not limited to this, and in other embodiments, the length dimensions of the abutting surface 712 and the convex tooth portion 731 in the third direction can also be set to be unequal.

[0055] Please refer to Figures 1 to 3 In one embodiment of the present application, the sliding platform 70 includes a platform body 71 and a fixed plate 73, the platform body 71 has a first surface 715, and the first surface 715 is provided with abutment 711; the fixed plate 73 is arranged on the first surface 715 and is relatively spaced apart from the abutment 711, and the fixed plate 73 is provided with a convex tooth portion 731 on the side facing the abutment 711.

[0056] In this embodiment, the sliding platform 70 is configured to include a platform body 71 and a fixed plate 73, so that the sliding platform 70 can be split into two parts, the platform body 71 and the fixed plate 73. At this time, the structures of the sliding platform 70 and the fixed plate 73 are relatively simple, and the two can be manufactured separately, and then assembled together to form a sliding platform 70 as a whole, thereby improving the convenience of manufacturing the sliding platform 70. In addition, the platform body 71 can also have a second surface 716 opposite to the first surface 715, and the second surface 716 can be used to install an object to be moved. At this time, the object to be moved and the belt 50 can be connected to the opposite sides of the platform body 71, respectively, thereby realizing full utilization of the space on the opposite sides of the platform body 71, so as to improve the compactness of the distribution between the several and the convenience of installation and arrangement.

[0057] Please refer to Figure 1 or Figure 2 In one embodiment of the present application, the abutting portion 711 includes a strip plate body provided on the first surface 715, so that the abutting portion 711 can abut the belt body 51 more fully. In other embodiments, the abutting portion 711 can also include a plurality of sub-plate bodies, and the plurality of sub-plate bodies can be arranged in sequence along the first direction. Among them, the abutting portion 711 can be integrally formed with the platform body 71, or the abutting portion 711 can be fixed on the first surface 715 by welding, fasteners, etc.

[0058] Please refer to Figure 1 or Figure 2 In one embodiment of the present application, the projection of the fixing plate 73 on the first surface 715 is located on the inner side of the platform body 71 .

[0059] In this embodiment, the projection of the fixing plate 73 is arranged to be located inside the platform body 71, so that in the first direction, the length dimension of the fixing plate 73 is smaller than the length dimension of the platform body 71. At this time, the two ends of the fixing plate 73 located inside the belt 50 can be far away from the driving wheel 10 and the driven wheel 30 also located inside the belt 50. In this way, the possibility of collision and interference between the fixing plate 73 and the driving wheel 10 or the driven wheel 30 can be reduced when the sliding platform 70 follows the belt 50 to slide, thereby facilitating the improvement of the safety of the sliding platform 70 in the process of following the movement of the belt 50. Of course, in other embodiments, it is also possible to arrange the two ends of the fixing plate 73 in the first direction to be flush with the two sides of the platform body 71 in the first direction or to protrude from the platform body 71.

[0060] In one embodiment of the present application, the fixing plate 73 is detachably connected to the platform body 71 .

[0061] In this embodiment, the fixing plate 73 is configured to be detachable, so that when the fixing plate 73 is damaged, it can be directly detached from the platform body 71, which is conducive to improving the convenience of its maintenance and replacement. Among them, the detachable connection of the fixing plate 73 can be connected by a screw connection 75 as described below, or it can be connected by a snap connection or magnetic fixation. In some other embodiments, the fixing plate 73 and the platform body 71 can also be fixedly connected.

[0062] Please refer to Figure 1 or Figure 2 In one embodiment of the present application, the fixing plate 73 is connected to the platform body 71 via a screw connection 75 .

[0063] The screw connection member 75 may be a screw, which may pass through the fixing plate 73 and be inserted into the platform body 71, or may pass through the platform body 71 and be inserted into the fixing plate 73. Of course, the screw connection member 75 may also be a combination of a bolt and a nut, in which case the bolt may pass through the fixing plate 73 and the platform body 71, and the nut may be sleeved on one end of the bolt away from the nut.

[0064] In this embodiment, the fixing plate 73 is connected by a screw connection 75, and the screw connection has the advantages of being simple and reliable, thereby facilitating the installation stability of the fixing plate 73 on the platform body 71 and improving the convenience of disassembling and assembling the fixing plate 73. At the same time, the installation stability of the fixing plate 73 on the platform body 71 is better, ensuring the connection stability between the belt 50 and the sliding platform 70.

[0065] Please refer to Figures 1 to 3In one embodiment of the present application, a positioning portion 713 is further provided on the first surface 715 , and the positioning portion 713 abuts against a side of the fixing plate 73 away from the protruding tooth portion 731 .

[0066] In this embodiment, the fixing plate 73 can be positioned on the platform body 71 by the positioning portion 713, which is conducive to improving the accuracy of the fixing plate 73 being installed on the platform body 71, and further facilitates the fixing plate 73 to ensure the accurate and stable spacing between the convex tooth portion 731 and the corresponding abutment portion 711 after installation, so that the belt 50 can be smoothly installed between the convex tooth portion 731 and the abutment portion 711 later. In addition, the positioning portion 713 can also support the fixing plate 73 to improve the stability of the fixing plate 73 installed on the platform body 71. The positioning portion 713 can be arranged opposite to the abutment portion 711, and an installation space is formed, and the fixing plate 73 is arranged in the installation space.

At the same time, the positioning portion 713 can be configured as a plate structure, so that the shape structure of the positioning portion 713 is relatively simple, thereby facilitating the improvement of the convenience of manufacturing the positioning portion 713. For example: the positioning portion 713 can be configured as a flat plate structure, or configured to include a plurality of sub-plates spaced apart in the first direction, and the positioning plane 714 can include sub-planes, each of which can be arranged on a sub-plate. Of course, in some embodiments, the positioning portion 713 can also include a plurality of columns arranged in sequence in the first direction.
