Description

Technical Field

[0001] This invention relates to the field of tooling, and more particularly to a material handling device. Background Technology

[0002] Material handling devices typically require lifting and lateral movement of materials during material handling. To achieve simultaneous lateral and longitudinal movement, existing technologies often employ two drive motors with lead screws: one for lateral movement and the other for longitudinal movement. The longitudinal movement device is connected to the lateral movement device, and both motors operate simultaneously to lift and move the material laterally. However, this structure is relatively expensive due to the use of two motors, and the reciprocating motion requires constant forward and reverse rotation, necessitating high levels of motor control.

[0003] Patent publication number CN214454950U discloses a precision cam-based pick-and-place mechanism, including a base, bearings, a central shaft, a transverse guide rail, a slide, two vertical guide rails, a swing arm, and a motor. The front side of the base is provided with an inverted U-shaped guide groove. The bearing is adapted to the guide groove and moves back and forth along the guide groove. By using the motor to drive the swing arm, in conjunction with the left-right and up-down movement of the transverse and longitudinal guide rails, the mechanism realizes the grabbing, handling, and releasing actions of the product. It enables the item to be grabbed from one place and placed in another place by moving a distance. Although this pick-and-place structure uses only one motor to realize the lifting and lateral movement of materials, it still requires the motor to rotate in both directions to achieve the reciprocating handling, resulting in relatively high control costs. Summary of the Invention

[0005] To achieve the above objectives, the main technical solutions adopted by the present invention include:

[0006] A material handling device, comprising:

[0007] Pick-and-place assembly, used for picking up and placing workpieces;

[0008] The first drive motor is used to drive the output shaft to rotate;

[0009] An eccentric wheel is connected to the output shaft to prevent rotation and allows the pick-and-place assembly to have lateral displacement.

[0010] The drive wheel is connected to the output shaft to prevent rotation and allows the pick-and-place assembly to have longitudinal displacement.

[0011] The vertical moving component is fixedly connected to the pick-and-place component;

[0012] A lateral moving component is connected to a longitudinal moving component; the longitudinal moving component is slidably connected to the lateral moving component and can move relative to the lateral moving component in the longitudinal direction; the lateral moving component is connected to an eccentric wheel through a first guide member; the first guide member has a lateral displacement under the action of the eccentric wheel, thereby driving the lateral moving component to have a lateral displacement;

[0015] Furthermore, the first drive motor is connected to the synchronous pulley on the output shaft via a synchronous belt; the first drive motor is fixed on the mounting plate.

[0016] Furthermore, the longitudinal moving component includes a longitudinal connecting member connected to the pick-and-place component; the longitudinal connecting member is provided with a transverse slider connected to the reset component.

[0018] Furthermore, the first guide includes a first connecting shaft connected to the lateral movement assembly; the eccentric wheel is connected to the output shaft for anti-rotation via a connecting hole; and a gap is provided between the eccentric wheel and the drive wheel.

[0023] Furthermore, it also includes a support assembly; the support assembly is provided with a support platform; the material handling device is disposed on the support platform.

[0024] The beneficial effects of this invention are as follows: The second return spring in this invention not only presses the first guide member onto the eccentric wheel, but also achieves self-locking at a specific position.

[0036] like Figure 1-3 As shown, a material handling device includes a handling component 100, a first drive motor 200, an eccentric wheel 240, a drive wheel 250, a longitudinal movement component 400, a transverse movement component 300, and a reset component 500. The handling component 100 is used to handle workpieces and can be operated using a robotic arm or vacuum suction cup commonly used in the prior art. The handling component 100 is connected to the longitudinal movement component 400, and the longitudinal movement component 400 is connected to the transverse movement component 300, thereby enabling the handling component 100 to move in the transverse and longitudinal directions and to transport the workpiece.

[0037] In one embodiment, the first drive motor 200 drives the output shaft 230 to rotate; the output shaft 230 is provided with an eccentric wheel 240 and a drive wheel 250; both the eccentric wheel 240 and the drive wheel 250 are anti-rotationally connected to the output shaft 230; the anti-rotation connection is usually a keyed connection; in one embodiment, the output shaft 230 can also be configured with a flat-head structure to achieve anti-rotation connection with the eccentric wheel 240 and the drive wheel 250; the eccentric wheel 240 drives the lateral movement component 300 to have lateral displacement, thereby... This allows the pick-and-place component 100 to have lateral displacement; the lateral movement component 300 is connected to the longitudinal movement component 400; the longitudinal movement component 400 is slidably connected to the lateral movement component 300 and can move longitudinally relative to the lateral movement component 300; the lateral movement component 300 is connected to the eccentric wheel 240 via a first guide member 330; the first guide member 330 has lateral displacement under the action of the eccentric wheel 240, thereby driving the lateral movement component 300 to have lateral displacement; the drive wheel 250 drives the longitudinal movement component 100 to have lateral displacement. The moving component 400 has longitudinal displacement, which in turn causes the picking and placing component 100 to have longitudinal displacement; the reset component 500 is connected to the longitudinal moving component 400 and can reset the longitudinal moving component 400's displacement in the lateral and longitudinal directions; the reset component 500 is connected to the drive wheel 250 through the second guide member 540; the drive wheel 250 is provided with two limiting grooves 251 that cooperate with the second guide member 540; in one embodiment, the limiting grooves 251 are arranged opposite to each other, corresponding to two moving positions respectively; when the second guide member 540 cooperates with the limiting groove 251, it is located at a low position, and when it cooperates with the non-limiting groove 251 area, it is located at a high position, so that the second guide member 540 has longitudinal displacement under the action of the drive wheel 250, which in turn drives the longitudinal moving component 400 to have longitudinal displacement through the reset component 500; the present invention realizes the simultaneous lateral and longitudinal displacement of the picking and placing component 100 through a first drive motor 200, thereby effectively handling the workpiece, greatly reducing costs, and at the same time, the reset component 500 can effectively reduce energy consumption.

[0038] In one embodiment, multiple limiting grooves 251 can be provided on the second guide member 540 to realize the handling at multiple positions; preferably, two limiting grooves 251 are provided, and the two positions represent the pick-up and placement positions of the workpiece, respectively.

[0039] In one embodiment, the first drive motor 200 is connected to a synchronous pulley 220 on the output shaft 230 via a synchronous belt 210; the first drive motor 200 is fixed on the mounting plate 260; it should be noted that the motor transmission shaft of the first drive motor 200 is also provided with another synchronous pulley 220 that cooperates with the synchronous belt 210; a bearing is usually also fitted between the output shaft 230 and the mounting plate 260, and such connection methods are common in the art; in another embodiment, the first drive motor 200 can also directly drive the output shaft 230 to rotate via a belt; in one embodiment, the first drive motor 200 can directly drive the output shaft 230 to rotate;

[0040] In one embodiment, the longitudinal moving component 400 includes a longitudinal connector 410; the longitudinal connector 410 is used to fix the pick-and-place component 100; a transverse slider 420 is also connected to the longitudinal connector 410; the transverse slider 420 is used to connect to the reset component 500, and can be used in conjunction with the second reset spring 561 to reset the longitudinal moving component 400 in the transverse displacement.

[0041] In one embodiment, the lateral movement component 300 includes a first slider 310 slidably connected to a lateral guide rail 261; the lateral guide rail 261 is fixedly connected to a mounting plate 260; the lateral movement component 300 can only move in the lateral direction; the lateral movement component 300 is provided with a longitudinal guide groove 320; the longitudinal movement component 400 is slidably connected to the longitudinal guide groove 320 via a longitudinal slider 430; thereby enabling the longitudinal movement component 400 to move laterally in addition to its own longitudinal movement, it can also be driven by the lateral movement component 300 to move laterally.

[0042] In one embodiment, the reset assembly 500 includes two opposing longitudinal guide blocks 510 fixedly connected to the mounting plate 260; each longitudinal guide block 510 is slidably connected to a first guide rod 520; both ends of the first guide rod 520 extend beyond the longitudinal guide block 510; the first guide rod 520 is typically a circular rod, capable of moving longitudinally relative to the longitudinal guide block 510; a first fixing rod 530 is fixedly connected to the top of the first guide rod 520, and each end of the first fixing rod 530 is connected to the top of one of the first guide rods 520; a second guide member 540 is connected to the first fixing rod 530; a connecting block 550 is connected to the bottom of each of the two first guide rods 520; and a sleeve is fitted on the first guide rod 520. A first return spring 521 is provided; in one embodiment, the first return spring 521 is disposed between the bottom of the longitudinal guide block 510 and the top of the connecting block 550. The first return spring 521 is normally always compressed, thereby providing elastic force at all times to press the second guide member 540 against the drive wheel 250, ensuring that the drive wheel 250 can effectively drive the second guide member 540 to move when it is working; in one embodiment, the first return spring 521 is disposed between the top of the longitudinal guide block 510 and the bottom of the first fixed rod 530; a second guide rod 560 is provided between the connecting blocks 550; the transverse slider 420 is slidably connected to the second guide rod 560; a second return spring 561 is provided on the second guide rod 560; the second return spring 561 is disposed between the connecting block 550 and the transverse slider 420, such as Figure 1 As shown, the second return spring 561 is located on the left side of the second guide rod 560. The second return spring 561 is usually always compressed, so as to provide elastic force at all times and ensure that the first guide member 330 is in close contact with the eccentric wheel 240.

[0043] In one embodiment, the second guide member 540 is connected to the first fixed rod 530 via an extension block 541; the extension block 541 facilitates control of the distance between the second guide member 540 and the first fixed rod 530; the first guide member 330 and the extension block 541 can be integrally formed, or the second guide member 540 can be configured as a rotatable structure; when the second guide member 540 is configured as a rotatable structure, the rotation of the drive wheel 250 to drive the second guide member 540 can be more effortless; the second guide member 540 always abuts against the outside of the drive wheel 250; in one embodiment, the first guide member 330 includes a first connecting shaft 331 connected to the lateral movement assembly 300; the first connecting shaft 331 allows the first guide member 330 to rotate, and the eccentric wheel 240 can push the first guide member 330 more effortlessly; in one embodiment, the first connecting shaft 331... The shaft 331 can also be interference-fitted with the lateral movement component 300, so that the first guide member 330 itself cannot rotate, while the corresponding eccentric wheel 240 can still effectively cooperate with the first guide member 330. It should be noted that the first guide member 330 is usually circular, but not limited to circular. The first guide member 330 can also be semi-circular, square, triangular or other polygonal. Under normal circumstances, when the first guide member 330 has a relatively flat plane that abuts against the outside of the eccentric wheel 240, it will not affect the rotation of the eccentric wheel 240. Since the second guide member 540 needs to cooperate with the limiting groove 251 and needs to be able to slide smoothly out of the limiting groove 251, the second guide member 540 is preferably circular, specifically cylindrical. In some special cases, the second guide member 540 can also be semi-cylindrical, and the semi-cylindrical arc surface cooperates with the limiting groove 251 and the outer wall of the drive wheel 250, which can also move smoothly.

[0044] In one embodiment, the eccentric wheel 240 is anti-rotatingly connected to the output shaft 230 via a connecting hole 241; a spacer 242 is provided between the eccentric wheel 240 and the drive wheel 250; the spacer 242 is typically an integrally protruding structure on the eccentric wheel 240; in one embodiment, the spacer 242 may also be an integrally protruding structure on the drive wheel 250; in one embodiment, the spacer 242 may be a separate component; by providing the spacer 242, the distance between the eccentric wheel 240 and the drive wheel 250 is separated, ensuring that the first guide member 330 and the eccentric wheel 240 have reasonable mating dimensions, and the second guide member 540 and the drive wheel 250 also have reasonable mating dimensions, thus avoiding interference;

[0045] In one embodiment, two second guide rods 560 are arranged in parallel; this can increase the straightness during lateral movement.

[0046] In one embodiment, a material handling device is disposed on a support assembly 600; a support platform 610 is provided on the support assembly 600; the material handling device is disposed on the support platform 610; in one embodiment, the mounting plate 260 is connected to the support platform via a support column 262; in one embodiment, the mounting plate 260 and the support column 262 can be an integral structure; in one embodiment, a second drive motor 270 is provided on the support platform; the second drive motor 270 is used to drive the displacement of the worktable 280, the worktable 280 being used to place workpieces.

[0047] Working principle: such as Figure 1 At this time, the position of the pick-and-place device is biased to the right, and the second guide 540 is located in the limiting groove 251. The second guide 540 is in a low position, and the corresponding pick-and-place component 100 is in a low position. The pick-and-place component 100 is in the initial position for gripping the workpiece. A material conveying device (not shown in the figure) is provided below the pick-and-place component 100. The material conveying device can be a conveyor belt or a vibrating conveyor, which are common technical means in this field and will not be described in detail here. The first drive motor 200 drives the output shaft 230 to rotate counterclockwise. The rotation of the eccentric wheel 240 will push the first guide 330 to move to the left, thereby driving the lateral movement. The moving component 300 moves to the left, thereby causing the longitudinal moving component 400 and the pick-and-place component 100 to move to the left; simultaneously, the rotation of the drive wheel 250 also pushes the second guide block upward, thereby causing the first fixed rod 530 and the second guide rod 560 to move upward, which in turn causes the longitudinal moving component 400 and the pick-and-place component 100 to move upward; the pick-and-place component 100 forms a compound motion of moving to the left and upward simultaneously. Furthermore, after the drive wheel 250 rotates 180°, the second guide member 540 will fall into the limiting groove 251 on the opposite side, and the latter half of the pick-and-place component 100 will perform a compound motion of moving to the left and downward, ultimately as follows: Figure 4 In the current state, the first guide member 330 and the connecting hole 241 are on the same horizontal plane, that is, the central axis of the first guide member 330 and the center line of the connecting hole 241 are on the same horizontal plane, forming a self-locking structure; the elastic force of the second return spring 561 is transmitted to the first guide member 330, and the force applied by the first guide member 330 to the eccentric wheel 240 passes through the center of the connecting hole 241, thus preventing the eccentric wheel 240 from rotating; during the above movement process, the first return spring 521 undergoes a compression-release process, thereby ensuring that the second guide member 540 is always in contact with the outer wall of the drive wheel 250; the second return spring 561 is always further compressed; from Figures 4 to 1In this state, the output shaft 230 rotates counterclockwise. At this time, the rotation of the eccentric wheel 240 causes the pressure applied by the first guide member 330 to the eccentric wheel 240 to not pass through the center of the connecting hole 241. The compressed elastic force of the second return spring 561 can be effectively released, thereby allowing the first guide member 330 to push the eccentric wheel 240 to rotate further. Figure 1 The second return spring 561 in this invention not only presses the first guide member 330 against the eccentric wheel 240, but also achieves self-locking at a specific position. After releasing the self-locking, it can effectively release the elastic force and restore the workpiece to its original state. Figure 1 The second guide 540 and the drive wheel 250 work together to ensure the effectiveness of self-locking at a specific position. The present invention realizes the movement of the pick-and-place component 100 in the horizontal and vertical directions through a first drive motor 200, which improves the efficiency of pick-and-place, and has a low coefficient of friction and low energy consumption. It can also effectively utilize the elastic force of spring compression to reduce power consumption. The first drive motor 200 can output the same motion state regardless of whether it rotates forward or backward, reducing the possibility of errors and improving safety.

[0048] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent modifications made based on the content of the present invention specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of the present invention.
