[0040] like Figure 1-2As shown, this embodiment provides an automatic transportation device, including a mounting frame 1, a transmission mechanism 2 and a driving mechanism 3, the transmission mechanism 2 includes a transmission belt 21, a driving shaft 22 and a driven shaft 23, the driving shaft 22 and the driven shaft 23 are parallel to, spaced apart and rotatably arranged on the mounting frame 1 along the length direction of the mounting frame 1, the driving shaft 22 and the driven shaft 23 jointly tension the transmission belt 21; the driving mechanism 3 includes a driving cylinder 31, a transmission assembly 32 and a ratchet 33, the driving cylinder 31 is arranged on the mounting frame 1, the ratchet 33 is transmission-connected to one end of the driving shaft 22, the driving cylinder 31 is configured to drive the ratchet 33 to rotate through the transmission assembly 32, thereby driving the driving shaft 22 to rotate, the driving shaft 22 cooperates with the driven shaft 23 to realize the continuous rotation of the transmission belt 21, and then realizes the transportation of the workpiece on the transmission belt 21. Compared with the motor drive device in the traditional automatic transport equipment, this embodiment adopts the drive cylinder 31, the transmission assembly 32 and the ratchet 33 to realize the transmission of the workpiece by the transmission mechanism 2, which can greatly reduce the manufacturing cost of the automatic transport equipment and reduce the transmission cost of the workpiece.

[0041] In this embodiment, if Figure 3 As shown, the ratchet 33 is clamped with the driving shaft 22, and the connection method is simple and efficient. The specific clamping method includes but is not limited to a mortise and tenon structure or a latch, etc., which is not limited here. Of course, in other embodiments, the ratchet 33 and the driving shaft 22 can also be fixed by bolt connection or other methods, which is not limited here.

[0042] Continue as Figure 2 As shown, the transmission assembly 32 includes a rocker arm 321, a tenon 322 and an elastic member 323. One end of the rocker arm 321 is connected to the output end of the driving cylinder 31, and the ratchet 33 is rotatably arranged on the other end of the rocker arm 321; the tenon 322 is slidably arranged on the rocker arm 321 along the radial direction of the ratchet 33, and the first end of the tenon 322 can extend into the tooth groove of the ratchet 33; an elastic member 323 is arranged between the second end of the tenon 322 and the rocker arm 321; the driving cylinder 31 can drive the rocker arm 321 to rotate with the center of the ratchet 33 as the rotation center, so that the tenon 322 moves along the radial direction of the ratchet 33, and at the same time pushes the ratchet teeth of the ratchet 33 to drive the ratchet 33 to rotate.

[0043] For example, Figure 2 and Figure 3 As shown, for the convenience of description, the tooth groove directly facing the tenon 322 at a certain moment is called the first tooth groove 331, and the tooth groove adjacent to the first tooth groove 331 and located in the rotation direction of the first tooth groove 331 along the ratchet 33 ( Figure 3The tooth groove on the rear side (in the direction indicated by the middle arrow) is called the second tooth groove 332, and the three ratchet teeth surrounding the first tooth groove 331 and the second tooth groove 332 are respectively called the first ratchet tooth 333, the second ratchet tooth 334 and the third ratchet tooth 335, wherein the second ratchet tooth 334 is located between the first ratchet tooth 333 and the third ratchet tooth 335, and the first ratchet tooth 333 is located on the front side of the second ratchet tooth 334 along the rotation direction of the ratchet wheel 33, and the third ratchet tooth 335 is located on the rear side of the second ratchet tooth 334 along the rotation direction of the ratchet wheel 33. When the output end of the driving cylinder 31 is extended, the rocker arm 321 rotates with the center of the ratchet wheel 33 as the rotation center, and the tenon 322 moves along the radial direction of the ratchet wheel 33 toward the center of the ratchet wheel 33 while rotating with the rocker arm 321, and pushes the first ratchet tooth 333 to rotate the ratchet wheel 33; when the output end of the driving cylinder 31 is retracted, the ratchet wheel 33 is fixed, and the rocker arm 321 rotates in the opposite direction with the center of the ratchet wheel 33 as the rotation center, at this time, the tenon 322 can slide into the second tooth groove 332 along the second ratchet tooth 334 toward the side of the first tooth groove 331; reciprocating, thereby realizing the rotation of the ratchet wheel 33. The setting of the elastic member 323 can ensure that the tenon 322 smoothly slides from the first tooth groove 331 over the second ratchet tooth 334 into the second tooth groove 332.

[0044] In order to prevent the ratchet 33 from reversing when the output end of the driving cylinder 31 is retracted, in this embodiment, the two tooth surfaces of the ratchet teeth between two adjacent tooth grooves on the ratchet 33 are arranged in such a manner that the angle between the tooth surface facing the front side of the rotation direction of the ratchet 33 and the groove bottom of the tooth groove corresponding to the side is an obtuse angle, and the angle between the tooth surface facing the rear side of the rotation direction of the ratchet 33 and the groove bottom of the tooth groove corresponding to the side is a right angle. Adaptively, the first end of the tenon 322 is adapted to the tooth groove on the ratchet 33, and can be tightly abutted against the groove bottom of any tooth groove and the tooth surfaces on both sides of the groove bottom. For the convenience of description, the side of the first end of the tenon 322 that abuts against the tooth surface on the front side of the rotation direction of the ratchet 33 is referred to as the first side, and the side of the first end of the tenon 322 that abuts against the tooth surface on the rear side of the rotation direction of the ratchet 33 is referred to as the second side. When the output end of the driving cylinder 31 is extended, the first side of the tenon 322 cooperates with the tooth surface of the first ratchet tooth 333 on the rear side of the rotation direction of the ratchet 33 to realize the rotation of the ratchet 33; when the output end of the driving cylinder 31 is retracted, the second side of the tenon 322 cooperates with the tooth surface of the second ratchet tooth 334 on the front side of the rotation direction of the ratchet 33, so that the tenon 322 can smoothly extend from the first tooth groove 331 over the second ratchet tooth 334 into the second tooth groove 332. Since the angle between the tooth surface facing the front side of the rotation direction of the ratchet 33 and the bottom of the tooth groove corresponding to this side is an obtuse angle, when the output end of the driving cylinder 31 retracts, the second surface of the tenon 322 slides along the tooth surface of the second ratchet tooth 334 toward the front side of the rotation direction of the ratchet 33 and moves along the radial direction of the ratchet 33 away from the ratchet 33 until it enters the next tooth groove without pushing the ratchet 33 to reverse.

[0045] like Figure 4 Combination Figure 2 As shown, a receiving chamber 3211 for receiving the ratchet 33 is provided at one end of the rocker arm 321 away from the driving cylinder 31, and a sliding groove 3212 communicating with the receiving chamber 3211 is also provided on the rocker arm 321, and the tenon 322 is slidably provided in the sliding groove 3212. By providing the receiving chamber 3211 on the rocker arm 321, the ratchet 33 and the rocker arm 321 can be assembled, and the stability of the relative movement between the two can be ensured; by providing the sliding groove 3212 on the rocker arm 321, a guide can be provided for the movement of the tenon 322 to ensure that it has a stable movement trajectory, so that the ratchet 33 can rotate stably.

[0046] Among them, a detachable protective structure 3213 is also provided in the sliding groove 3212, and the elastic member 323 and the tenon 322 are sequentially inserted into the protective structure 3213, and the first end of the tenon 322 can extend out of the protective structure 3213 and enter into the tooth groove of the ratchet 33. By setting the protective structure 3213, the elastic member 323 and the tenon 322 can be prevented from falling off from the side opening of the sliding groove 3212; and by setting the detachable protective structure 3213, the elastic member 323 and the tenon 322 are limited, and there is no need to disassemble the entire transmission assembly 32 during installation and disassembly, which can facilitate the installation and disassembly of the elastic member 323 and the tenon 322.

[0047] Continue as Figure 1 As shown, the conveying mechanism 2 further includes a material discharge portion 24, which is disposed on the mounting frame 1 and is located downstream of the transmission belt 21. The material discharge portion 24 gradually extends from top to bottom in a direction away from the transmission belt 21, and the workpiece enters the material discharge portion 24 after being transported by the transmission belt 21. By providing the material discharge portion 24, the conveying mechanism 2 can be docked with the next station whose height is lower than the transmission surface of the transmission belt 21, ensuring that the workpiece on the conveying mechanism 2 can be smoothly transported to the next station.

[0048] In order to limit the moving range of the workpiece, the automatic transport device further includes a first limiting mechanism 4, which includes a first limiting portion 41 located outside the unloading portion 24, and a first limiting space is formed between the first limiting portion 41 and the unloading portion 24, and the workpiece on the transmission belt 21 can be transferred to the next station through the first limiting space. It should be noted that the outside of the unloading portion 24 refers to the side of the unloading portion 24 away from the mounting frame 1.

[0049] Furthermore, the opening of the first limiting space toward the upstream direction of the transmission belt 21 is flared, so that the workpiece can smoothly enter the first limiting space and avoid being stuck by the first limiting portion 41. Specifically, the first limiting portion 41 includes at least two limiting rods spaced apart in a direction perpendicular to the transmission direction of the transmission belt 21, and the portion of the limiting rod facing the upstream of the transmission belt 21 is bent upward to form the flared opening of the first limiting space.

[0050] The first limiting mechanism 4 further includes a first adjusting component 42, which is configured to adjust the distance between the first limiting portion 41 and the blanking portion 24, thereby adjusting the size of the first limiting space according to the size of the workpiece or the preset moving range of the workpiece.

[0051] In this embodiment, the first adjustment assembly 42 includes an adjustment column 421, an adjustment bolt 422 and an adjustment plate 423. The adjustment plate 423 extends in a direction perpendicular to the transmission direction of the transmission belt 21. At least two limit rods are arranged on the adjustment plate 423. One end of the adjustment column 421 is connected to the adjustment plate 423, and the other end is slidably penetrated on the mounting frame 1. The adjustment bolt 422 is threadedly connected to the adjustment plate 423 and abuts against the mounting frame 1. When it is necessary to adjust the spacing between the first limit portion 41 and the blanking portion 24, the operator can screw the adjustment bolt 422 so that the adjustment plate 423 is close to or away from the mounting frame 1 along the axis direction of the adjustment column 421 under the limiting action of the adjustment column 421. When the adjustment plate 423 is adjusted to a preset position, the height of the adjustment plate 423 can be locked by fixing the adjustment column 421 relatively to the mounting frame 1, thereby realizing the locking of the first limit portion 41 relative to the blanking portion 24 at any position. The fixing method of the adjustment column 421 and the mounting frame 1 includes, but is not limited to, threaded connection or clamping, etc., which is not limited here.

[0052] Of course, in other embodiments, one end of the adjustment column 421 can be connected to the mounting frame 1, and the other end can be slidably penetrated into the adjustment plate 423; or the adjustment bolt 422 can be threadedly connected to the mounting frame 1 and abutted against the adjustment plate 423, which can also achieve the above effect.

[0053] Optionally, the spacing between two adjacent limit rods is adjustable. Specifically, a strip groove extending in a direction perpendicular to the transmission direction of the transmission belt 21 is provided on the adjustment plate 423, and each limit rod can correspond to a fastener, and each fastener can pass through the strip groove and be fixed on the corresponding limit rod. When it is necessary to adjust the spacing between two adjacent limit rods, the fastener can be loosened first, and then the corresponding limit rod can be slid to a suitable position along the extension direction of the strip groove, and finally the fastener can be tightened. By adjusting the spacing between two adjacent limit rods, it can be prevented that when the width of the workpiece is narrow, it falls from the gap between the two limit rods during the transmission process.

[0054] like Figure 1 and Figure 5As shown, the automatic transport device further includes an intermediate reversing mechanism 5, which includes a guide member 51 located below the unloading portion 24. The workpiece transferred from the unloading portion 24 to the top of the guide member 51 is transferred to the next station after being flipped by collision with the guide member 51. This design method can realize the automatic flipping of the workpiece to adapt it to the operation requirements of the next station.

[0055] Optionally, the intermediate reversing mechanism 5 also includes a second limiting portion 52, and the spacing between the second limiting portion 52 and the guide member 51 in the transmission direction of the transmission belt 21 is equal to or slightly larger than the size of the workpiece along the transmission direction when the workpiece is transmitted on the transmission belt 21. The workpiece is transmitted in the second limiting space defined between the guide member 51 and the second limiting portion 52 to ensure that the workpiece can be stably transmitted to the next workstation after colliding with the top of the guide member 51.

[0056] Continue as Figure 1 As shown, in the present embodiment, the number of the second limiting portions 52 is two, and the two second limiting portions 52 are arranged at intervals in a direction perpendicular to the transmission direction of the transmission belt 21, and the spacing between the two second limiting portions 52 is smaller than the width of the workpiece, so as to reduce the material used for the second limiting portions 52 and reduce the processing cost while achieving effective limiting of the workpiece.

[0057] Optionally, the intermediate reversing mechanism 5 further includes a second adjusting component 53 , each second position limiting portion 52 corresponds to a second adjusting component 53 , and the second adjusting component 53 is configured to adjust the distance between the corresponding second position limiting portion 52 and the guide member 51 . Specifically, in the present embodiment, the second adjustment component 53 comprises a first adjustment portion 531, an intermediate connection portion 532 and a second adjustment portion 533. The first adjustment portion 531 is mounted on the mounting frame 1 and is provided with a first adjustment slot extending along the transmission direction of the transmission belt 21; the intermediate connection portion 532 is slidably arranged on the first adjustment portion 531 along the transmission direction of the transmission belt 21, and the first locking member can pass through the first adjustment slot and lock on the intermediate connection portion 532 to lock the relative position between the first adjustment portion 531 and the intermediate connection portion 532; the intermediate connection portion 532 is provided with an adjustment hole penetrating in a direction perpendicular to the transmission direction of the transmission belt 21, one end of the second adjustment portion 533 is slidably arranged in the adjustment hole of the intermediate connection portion 532, and the other end is connected to the corresponding second limiting portion 52; the second locking member can lock the relative position between the second adjustment portion 533 and the intermediate connection portion 532. With the above arrangement, the distance between the two second limiting portions 52 and the distance between the second limiting portion 52 and the guide member 51 can be adjusted, thereby adapting to the transmission of workpieces of different sizes.

[0058] Alternatively, if Figure 5As shown, the intermediate reversing mechanism 5 also includes a guide adjustment component 54, which includes a first guide adjustment member 541, a second guide adjustment member 542 and a third guide adjustment member 543. The first guide adjustment member 541 is installed on the mounting frame 1 and is located below the unloading portion 24. The first guide adjustment member 541 is provided with a second adjustment groove extending in a direction perpendicular to the transmission direction of the transmission belt 21; the second guide adjustment member 542 is slidably arranged on the first guide adjustment member 541 in a direction perpendicular to the transmission direction of the transmission belt 21, and the third locking member can lock the relative position between the first guide adjustment member 541 and the second guide adjustment member 542; the third guide adjustment 543 is an L-shaped structure, and the vertical portion of the third guide adjustment 543 is rotatably connected to the second guide adjustment member 542; the guide member 51 is provided with a third adjustment groove extending in the transmission direction of the transmission belt 21, and the horizontal portion of the third guide adjustment 543 is provided with a plurality of locking holes arranged at intervals along the transmission direction of the transmission belt 21, and the fourth locking member can pass through the third adjustment groove and selectively lock in any locking hole. By adopting the above-mentioned setting method, it is possible to adjust the distance between the guide member 51 and the unloading part 24 in the transmission direction along the transmission belt 21 and the material receiving position and angle of the guide member 51 to ensure that the guide member 51 can collide with the workpiece to change the direction in which the workpiece falls.

[0059] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention.
