[0038] To address the problems of large space occupation, low power transmission accuracy, and poor handling efficiency in related technologies, this invention provides a handling device that improves handling efficiency by shortening the handling distance and enabling the transfer of items to be handled.
[0039] like Figures 1 to 8As shown, the handling device includes a base 10, a rotary drive 20, a rotary assembly, a picking assembly, and a connecting rod assembly 60. A fixed shaft 140 is provided on the top surface of the base 10. The rotary drive 20 is mounted on the base 10. The rotary assembly includes a first bushing 410 and a second bushing 430 fixedly connected. The first bushing 410 is rotatably sleeved on the fixed shaft 140. The rotary drive 20 is drivenly connected to the first bushing 410. The picking assembly includes at least a rotary shaft 510 and a gripping mechanism 520 disposed on the rotary shaft 510.

The connecting rod assembly 60 includes a first crank 610 connected to the fixed shaft 140, a second crank 630 connected to the rotary shaft 510, and a rocker arm 620. The two ends of the rocker arm 620 are rotatably connected to the first crank 610 and the second crank 630, respectively.
[0040] Specifically, the handling device provided by this invention can achieve the effect of cyclic handling of workpieces and products, greatly shortening the handling distance and easily realizing the handling of items over short distances, thereby improving the practicality and timeliness of the equipment. Furthermore, the use of mechanical means eliminates the need for manual intervention, avoiding human error, improving the speed and accuracy of cyclic handling, reducing labor costs, and increasing the rate of cyclic handling, further enhancing handling efficiency. Simultaneously, compared to the assembly line structure in the prior art, the handling device of this application has the advantages of small footprint and good operational stability. Therefore, the handling device provided by this application can solve the problems of large space occupation, low power transmission accuracy, and poor handling efficiency of existing handling devices, achieving the effect of improving handling efficiency.
[0041] Furthermore, the base 10 includes a top plate 130, a floor, and a support column 120. One end of the support column 120 is disposed on the base plate 110, and the other end of the support column 120 is connected to the top plate 130. A fixed shaft 140 is disposed on the top plate 130 and extends in a direction away from the base plate 110. A rotary drive 20 is mounted on the top plate 130.
[0042] The top plate 130 and the bottom plate are spaced apart to form a mounting cavity. The rotary drive 20 is mounted on the top plate 130 by fasteners. To enhance the stability of the installation of the rotary drive 20, the rotary drive 20 can also be mounted on both the top plate 130 and the support column 120.
[0043] Furthermore, the rotary drive 20 is mounted on the end face of the top plate 130 facing the bottom plate 110, and the output shaft of the rotary drive 20 passes through the top plate 130 and is driven to connect with the first bushing 410. The output shaft extends in the same direction as the fixed shaft 140, and the top plate 130 is provided with a hole structure, through which the output shaft extends to the outside of the mounting cavity and is used for drive connection with the first bushing 410.
[0044] It should be noted that the rotary drive component 20 is a rotary motor or a rotary cylinder, which is designed to provide the first bushing 410 with rotary driving force.
[0045] like Figures 1 to 8 As shown, the fixed shaft 140 and the rotating shaft 510 are spaced apart and arranged in parallel. The rotating assembly also includes a swing arm 420. The first bushing 410 and the second bushing 430 are fixedly connected through the swing arm 420. The rotating drive 20 drives the rotating shaft 510 to rotate around the fixed shaft 140 through the rotating assembly.
[0046] One end of the swing arm 420 is fixedly connected to the first bushing 410, and the second end of the swing arm 420 is fixedly connected to the second bushing 430. When the rotary drive 20 drives the first bushing 410 to rotate around the fixed shaft 140, the first bushing 410 drives the second bushing 430 to rotate around the fixed shaft 140 through the swing arm 420, and the second bushing 430 drives the rotary shaft 510 to rotate synchronously.
[0047] Specifically, the swing arm 420 has a first position and a second position. When the swing arm 420 is in the first position, the gripping mechanism 520 is in the first gripping position. When the swing arm 420 rotates from the first position to the second position by a first angle, the swing arm 420 drives the rotating shaft 510 and the gripping mechanism 520 to rotate around the fixed shaft 140 by a first angle. At the same time, the first crank 610 drives the rotating shaft 510 and the gripping mechanism 520 to rotate by a first angle through the swing arm 620, and the gripping mechanism 520 rotates to the second gripping position.
[0048] During the rotation of the swing arm 420, the rotating shaft 510 rotates around the fixed shaft 140. When the rotating shaft 510 rotates, the first crank 610 drives the second crank 630 and the rotating shaft 510 to rotate around the rotating shaft 510 through the rocker arm 620.
[0049] Furthermore, the first bushing 410, the swing arm 420, and the second bushing 430 are integrally formed.
[0050] In this embodiment, when the first angle is 90°, the rotating shaft 510 and the gripping mechanism 520 rotate 90° around the fixed shaft 140. At the same time, the first crank 610 pulls the second crank 630 through the swing rod 620, causing the rotating shaft 510 and the gripping mechanism 520 to rotate 90° around the axis of the rotating shaft 510, that is, the gripping mechanism 520 rotates 180°.
[0051] Furthermore, the rocker arm 620 is arranged parallel to the rocker arm 420 of the rotating assembly.
[0052] Furthermore, the rocker arm 620 is set perpendicular to the extension direction of the fixed shaft 140.
[0053] Furthermore, the first crank 610 is fixedly connected to the end face of the fixed shaft 140 away from the base 10, and the second crank 630 is fixedly connected to the end face of the rotating shaft 510 away from the gripping mechanism 520.
[0054] like Figures 1 to 8 As shown, the connecting rod assembly 60 also includes a connecting shaft extending in the same direction as the fixed shaft 140, and the rocker arm 620 is rotatably connected to the first crank 610 and the second crank 630 through the connecting shaft.
[0055] Furthermore, the connecting shaft is fixedly connected to the rocker arm 620, and the connecting shaft is rotatably connected to the first crank 610 and the second crank 630.
[0056] Of course, it is not limited to the above-mentioned structure in which the connecting shaft and the rocker arm 620 are fixedly connected. It can also be that the connecting shaft and the rocker arm 620 are rotatably connected, and the connecting shaft is fixedly connected to the first crank 610 and the second crank 630.
[0057] like Figures 1 to 8 As shown, the conveying device also includes a transmission assembly 30, which includes a first transmission member 310 and a second transmission member 320. The rotary drive member 20 is drivenly connected to the first transmission member 310. The second transmission member 320 is disposed on the first bushing 410, and the first transmission member 310 and the second transmission member 320 are rotatably connected.
[0058] Specifically, the rotary drive 20 is rotatably connected to the first transmission member 310 and the second transmission member 320, thereby driving the first bushing 410 to rotate.
[0059] Furthermore, the first transmission member 310 is a first gear, and the second transmission member 320 is a second gear. The first gear has a through hole, and at least a portion of the output shaft of the rotary drive member 20 extends into the through hole, thereby fixing the first gear onto the output shaft. The second gear has a through hole, and the first bushing 410 passes through the through hole and is fixedly connected to the second gear. The first gear and the second gear mesh, and the rotary drive member 20 drives the first bushing 410 to rotate by meshing the first gear and the second gear.
[0060] In this embodiment, the number of teeth of the first gear is less than the number of teeth of the second gear, so that there is a transmission ratio between the first gear and the second gear. The transmission ratio can be adjusted by changing the number of teeth of the gears by replacing them.
[0061] like Figures 1 to 8 As shown, the gripping mechanism 520 includes a displacement drive 521, a mounting frame 523, and a gripping member 524. The displacement drive 521 is fixedly mounted on the rotating shaft 510 and connected to the mounting frame 523. The displacement drive 521 provides driving force for the mounting frame 523 to move up and down. The gripping member 524 is mounted on the mounting frame 523.
[0062] Specifically, the displacement drive 521 drives the mounting bracket 523 to move up and down, so that the mounting bracket 523 drives the gripper 524 to move up and down. The gripper 524 descends to grip the object to be gripped, and the gripper 524 rises to facilitate the transfer of the object to be gripped.
[0063] Furthermore, the mounting bracket 523 has a guide shaft 5231 extending along a first direction, and the gripper 524 is slidably mounted on the guide shaft 5231. The guide shaft 5231 has a guiding function so that the gripper 524 slides along the extension direction of the guide shaft 5231, thereby changing the position of the gripper 524 to grip objects at different positions.
[0064] The guide shaft 5231 is provided in one or more ways. When there are multiple guide shafts 5231, the multiple guide shafts 5231 are spaced apart along a second direction that is perpendicular to the first direction.
[0065] Furthermore, the gripping mechanism 520 also includes a bracket 525, which is slidably connected to the guide shaft 5231. Each bracket 525 is provided with one or more gripping elements 524. When multiple gripping elements 524 are provided, they are spaced apart along the second direction. A bracket 525 can be slidably mounted on one guide shaft 5231, or a bracket 525 can be slidably mounted on multiple guide shafts 5231 simultaneously. The structure of using multiple guide shafts 5231 is beneficial to enhancing the installation stability of the bracket 525, thereby improving the stability of the gripping elements 524.
[0066] Furthermore, one or more brackets 525 are provided. When multiple brackets 525 are provided, they are spaced apart along the first direction on the guide shaft 5231. When multiple brackets 525 are provided, multiple gripping elements 524 can be provided on each bracket 525. Thus, by moving the bracket 525, the positions of multiple gripping elements 524 can be moved simultaneously, which facilitates adjustment and improves gripping efficiency.
[0067] In this embodiment, the gripping mechanism 520 further includes a linear bearing 528. A bracket 525 is slidably connected to a guide shaft 5231 via the linear bearing 528. Along the height direction of the bracket 525, a first end of the bracket 525 is fixedly connected to the linear bearing 528, and a second end of the bracket 525 is detachably connected to the gripping member 524, thereby allowing the bracket 525 to be slidably mounted on the guide shaft 5231 via the linear bearing 528. To improve safety during use, a limiting ring is fitted onto the guide shaft 5231.
[0068] The bracket 525 has a mounting hole at its first end, and at least a portion of the linear bearing 528 is mounted inside the mounting hole to achieve the connection between the bracket 525 and the linear bearing 528.
[0069] Furthermore, the gripper 524 is snapped into the bracket 525 or the gripper 524 is connected to the bracket 525 by fasteners.
[0070] In this embodiment, the gripping component 524 is a suction cup, specifically a vacuum suction cup. The vacuum generator is mounted on the mounting bracket 523 and connected to the vacuum suction cup tube. The displacement driving component 521 is a telescopic motor or a telescopic cylinder.
[0071] like Figures 1 to 8 As shown, at least two brackets 525 are provided along the first direction. The gripping mechanism 520 also includes a spacing adjustment assembly, which includes a spacing adjustment drive 522, a positioning post, a locking shaft 527, a connecting rod 526, and a limiting assembly. The spacing adjustment drive 522 is mounted on the mounting bracket 523 and provides driving force for the brackets 525 to move along the first direction. Each bracket 525 is equipped with a positioning post. The spacing adjustment drive 522 is drivenly connected to the brackets 525 and / or the positioning posts. The locking shaft 527 forms a... In the configuration, two locking shafts 527 are arranged in pairs and spaced apart along the second direction to form a locking shaft group. A locking shaft group is provided between two adjacent brackets 525. The connecting rods 526 are arranged in pairs and are arranged crosswise between two adjacent locking shaft groups. The crosswise positions of the two connecting rods 526 can be rotatably sleeved on the positioning post. One of the locking shaft groups is slidably engaged with the mounting bracket 523 through a limiting component, so that the two locking shafts 527 in the pair in the locking shaft group move closer or further apart from each other along the second direction.
[0072] Specifically, two locking shafts 527 of a locking shaft group used in conjunction with the limiting component move closer to each other in the second direction, thereby causing other locking shaft groups to move away from each other in the first direction. At the same time, under the action of the linkage rod 526, two locking shafts 527 in other locking shaft groups move closer to each other in the second direction. Similarly, two locking shafts 527 of a locking shaft group used in conjunction with the limiting component move away from each other in the second direction, thereby causing other locking shaft groups to move closer to each other in the first direction. At the same time, under the action of the linkage rod 526, two locking shafts 527 in other locking shaft groups move away from each other in the second direction.
[0073] Since all the linkage rods 526 have the same length, the distance that the linkage rod 526 moves along with the positioning column is also the same, so as to achieve the effect of equidistant movement.
[0074] Furthermore, the spacing adjustment drive 522 is a telescopic motor or a telescopic cylinder.
[0075] Furthermore, the multiple brackets 525 are arranged in sequence as a first bracket, a second bracket, and a third bracket, with the direction away from the spacing adjustment drive member 522. The limiting component is disposed in the area between the first bracket and the second bracket, so that the multiple brackets 525 move closer to the position area of the limiting component.
[0076] It should be noted that only one limiting component is provided, allowing multiple brackets to approach or move away from the limiting component. The location of the limiting component is not limited to being between the first and second brackets; it can also be located between the second and third brackets.
[0077] In this embodiment, when the spacing adjustment drive 522 is in the extended state, the output shaft of the spacing adjustment drive 522 extends and the multiple supports 525 move closer to each other; when the spacing adjustment drive 522 is in the retracted state, the output shaft of the spacing adjustment drive 522 retracts and the multiple supports 525 move further apart.
[0078] Specifically, when the spacing adjustment drive 522 is in the retracted state, the spacing adjustment drive 522 drives the first bracket 525 to move toward the spacing adjustment drive 522, thereby enabling the two linkage rods 526 connected to the positioning post of the first bracket 525 to move with the first bracket 525, so that the locking shaft group between the displacement first bracket 525 and the second bracket 525 moves toward each other under the limitation of the limiting component, while under the action of the linkage rods 526, the other third brackets 525, etc., move at equal distances toward each other.
[0079] When the spacing adjustment drive 522 is in the extended state, the spacing adjustment drive 522 drives the first bracket 525 to move away from the spacing adjustment drive 522, thereby enabling the two linkage rods 526 connected to the positioning post of the first bracket 525 to move with the first bracket 525, so that the locking shaft group between the displacement first bracket 525 and the second bracket 525 moves away from each other under the limitation of the limiting component. At the same time, under the action of the linkage rods 526, other third brackets 525, etc., move at equal distances towards each other.
[0080] like Figures 1 to 8 As shown, the limiting component includes a first limiting member and a second limiting member 5232. The first limiting member is disposed on the end face of the locking shaft 527 facing the mounting bracket 523, and the second limiting member 5232 is disposed on the mounting bracket 523.
[0081] Furthermore, the first limiting member is a protruding structure, and the second limiting member 5232 is a sliding groove extending along the second direction. The protruding structure is slidably disposed inside the sliding groove. The protruding structure can be a cam, which slides inside the sliding groove, guiding the sliding between the first and second limiting members 5232, thereby allowing the two locking shafts 527 of the locking shaft assembly to move closer or further apart.
[0082] It should be noted that the first limiting member is not limited to a protruding structure, but can also be a groove structure, and the second limiting member is a limiting rib extending along the second direction. The limiting rib slides into the groove structure, and at least a portion of the limiting rib extends into the interior of the groove structure so that the groove structure slides into the limiting rib, thereby enabling the locking shaft 527 to move along the length direction of the limiting rib.
[0083] The operation steps of the conveying device of this application are as follows: A rotary drive 20 drives a first transmission component 310 to rotate. The first transmission component 310 and a second transmission component 320 are rotatably connected. The second transmission component 320 drives a first bushing 410 to rotate around a fixed shaft 140. The first bushing 410 drives a second bushing 430 to rotate around the fixed shaft 140 via a swing arm 420. The second bushing 430 drives a rotating shaft 510 to rotate around the fixed shaft 140. After the swing arm rotates 90°, the rotary drive 20 stops. While the swing arm rotates, the first crank 610 remains stationary. Therefore, during the rotation of the rotating shaft 510 and the second crank 630 around the fixed shaft 140, the swing arm 620 pulls the second crank 630 to cause the rotating shaft 510 to rotate 90°.
[0084] After the swing arm 420 rotates 90°, the gripping mechanism 520 rotates 90° around the fixed axis 140 and simultaneously rotates 90° on its own axis along with the rotating axis 510. That is, the gripping mechanism 520 rotates 180° to reach the preset position to grip the object to be gripped.
[0085] After the gripping mechanism 520 reaches the preset position, the displacement drive 521 drives the mounting bracket 523 to descend, while the spacing adjustment drive 522 extends or retracts to adjust the position of the gripping member 524, so as to adsorb the object to be gripped at the preset position. Then the displacement drive 521 drives the mounting bracket 523 to rise, completing the object retrieval.
[0086] After the object is picked up, the rotary drive 20 rotates in the opposite direction, which in turn drives the swing arm 420 to rotate 90° in the opposite direction to the initial position. At this time, the gripping mechanism 520 rotates 180° in the opposite direction to reach the placement position of the object to be gripped. The displacement drive 521 drives the mounting bracket 523 to descend, and the gripper 524 releases the gripper from adsorbing the object to be gripped and places the object to be gripped in the placement position. Then the displacement drive drives the gripper 524 to rise, completing one workflow. The workflow can be repeated.
