[0027] In order to facilitate the understanding of the present invention, specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.
[0028] Unless otherwise specified or defined, the "first, second..." used in this article is merely used to distinguish names and does not represent a specific quantity or order.
[0029] Unless specifically stated or defined otherwise, the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0030] It should be noted that, in this document, “fixed to” or “connected to” may mean directly fixing or connecting to an element, or indirectly fixing or connecting to an element.
[0031] It should be noted that the double-stroke drive mechanism 100 can be used to drive the workpiece to move to a preset position. Specifically, in this embodiment, the double-stroke drive mechanism 100 is mainly used to drive the slide rack and the slide thereon to move from a previous station to a next station. Of course, in other embodiments, the double-stroke drive mechanism 100 can also be used to drive the movement of workpieces in other fields, and no special limitation is made here.
[0032] The present utility model embodiment provides a double stroke driving mechanism 100, such as Figure 1 and Figure 2 As shown, the double stroke driving mechanism 100 includes a fixed seat 1, a first movable seat 2, a driving device 3, a second movable seat 4, a first transmission device and a motion conversion device 7.
[0033] The first movable seat 2 is movably disposed on the fixed seat 1 . The driving device 3 is connected to the first movable seat 2 and drives the first movable seat 2 to move linearly relative to the fixed seat 1 .
[0034] The second movable seat 4 is movably arranged on the first movable seat 2, and the motion conversion device 7 is also arranged on the first movable seat 2. The first movable seat 2 is connected to the motion conversion device 7 through the first transmission device, and the motion conversion device 7 is driven to rotate through the transmission action of the first transmission device. The motion conversion device 7 is connected to the second movable seat 4, and the motion conversion device 7 can convert the rotational motion into the linear motion of the second movable seat 4, so as to drive the second movable seat 4 to move linearly relative to the first movable seat 2. Among them, the motion conversion device 7 can be any device that can convert the rotational motion into the linear motion, and there is no special limitation here.
[0035] When the driving device 3 drives the first movable seat 2 to move forward relative to the fixed seat 1, the linear motion of the first movable seat 2 can form a rotational driving force of the motion conversion device 7 through the transmission action of the first transmission device, and the rotational drive is further converted into linear motion through the motion conversion device 7, which can synchronously drive the second movable seat 4 to move linearly relative to the first movable seat 2. Therefore, the double-stroke driving mechanism 100 can realize the movement of two movable seats under the drive of one driving device 3, that is, a single driving device 3 can simultaneously drive the movement of two movable seats to realize double-stroke driving, which can effectively reduce the structural volume and space occupancy rate.
[0036] Specifically, the first transmission device includes a gear 5 and a rack 6. The fixed seat 1 is provided with the rack 6 along the movement extension direction of the first movable seat 2. The gear 5 is provided on the first movable seat 2, and the rack 6 is meshed with the gear 5 for transmission. The gear 5 is connected to the second movable seat 4 through a motion conversion device 7. The first movable seat 2 can move forward during the driving process of the driving device 3, and the gear 5 is driven to move. Since the gear 5 and the rack 6 are meshed for transmission, the gear 5 will be meshed with the rack 6 during the movement process, thereby driving the gear 5 to rotate while moving forward. The gear 5 is connected to the second movable seat 4 through the motion conversion device 7. The motion conversion device 7 can convert the rotational motion of the gear 5 into the linear motion of the second movable seat 4, so as to drive the second movable seat 4 to move linearly relative to the first movable seat 2. Therefore, the double stroke driving mechanism 100 can realize the movement of two movable seats under the drive of one driving device 3, that is, a single driving device 3 can simultaneously drive the two movable seats to move to realize the double stroke drive, which can effectively reduce the structural volume and space occupancy rate. Of course, in other embodiments, the first transmission device may be other devices capable of converting linear motion into rotational motion, and no particular limitation is imposed herein.

Specifically, one side of the first synchronous belt 72 and located between the first driving wheel 71 and the first driven wheel 73 is connected to the second movable seat 4, thereby driving the second movable seat 4 to form a linear motion. Among them, the rotation of the gear 5 drives the first driving wheel 71 to rotate, and the transmission is realized between the first driving wheel 71 and the first driven wheel 73 through the first synchronous belt 72, wherein the first synchronous belt 72 drives the second movable seat 4 to move linearly through the first connecting member 74 during the transmission process. Specifically, a slot may be provided on the first connecting member 74 , and the slot is fixedly engaged with the first synchronous belt 72 , so that the linear movement of the first synchronous belt 72 between the first driving wheel 71 and the first driven wheel 73 can be converted into the linear movement of the second movable seat 4 .
[0038] In some embodiments, the extension direction of the rack 6 is the same as the tensioning direction of the first synchronous belt 72. Specifically, the first connecting member 74 and the side of the first synchronous belt 72 to be connected can be adjusted according to the movement direction to be formed by the second movable seat 4 relative to the first movable seat 2. For example, when the first movable seat 2 needs to move in the same direction as the second movable seat 4, the first connecting member 74 is connected to the side of the first synchronous belt 72 that is consistent with the movement direction of the first movable seat 2. When the first movable seat 2 needs to move in the opposite direction to the second movable seat 4, the first connecting member 74 is connected to the side of the first synchronous belt 72 that is opposite to the movement direction of the first movable seat 2. Specifically in the present embodiment, the first connecting member 74 is connected to the side of the first synchronous belt 72 that is consistent with the movement direction of the first movable seat 2, so that the first movable seat 2 and the second movable seat 4 move in the same direction, so as to form a double stroke movement under the drive of a driving device 3.

The driving source component 31 can be a stepping motor. Specifically, the driving source component 31 drives the second driving wheel 321 to rotate, and the transmission is realized between the second driving wheel 321 and the second driven wheel 323 through the second synchronous belt 322, wherein the second synchronous belt 322 drives the first movable seat 2 to move linearly through the second connecting member 324 during the transmission process. Among them, the second connecting member 324 may be provided with a card slot, and the card slot is fixedly engaged with the second synchronous belt 322. The transmission structure formed by the cooperation of the second driving wheel 321, the second synchronous belt 322, the second driven wheel 323 and the second connecting member 324 can make the output shaft of the driving source member 31 non-coaxial with the moving direction of the first movable seat 2, and can reduce the space occupied by the moving extension direction of the first movable seat 2.
