Description

Technical Field

[0001] This invention relates to the field of robotic gripper technology, specifically to an automated picking and placing mechanism for electronic cigarette hooks. Background Technology

[0002] In the large-scale automated production and processing of e-cigarettes, e-cigarette hooks are core micro-components used for assembling, positioning, and hanging e-cigarette components. Due to their small size and irregular shape, they are difficult to handle manually. This has led to the development of e-cigarette hook handling mechanisms to handle e-cigarette hooks. Specifically, a conventional operation method is adopted, which uses a vibratory feeder to sort and load e-cigarette hooks in a fixed vacuum adsorption system. The specific workflow is as follows: the vibratory feeder generates high-frequency micro-vibration to sort and arrange the large number of e-cigarette hooks stacked randomly in the hopper, and continuously transports them to the loading trough with a V-shaped bottom structure to complete the waiting position. Then, an industrial robot drives the handling component equipped with a fixed vacuum adsorption structure to move to the designated handling position. The adsorption holes with fixed angles and positions press down vertically to attempt to align with the square structure on the upper part of the hook, and then the handling operation is completed by negative pressure adsorption.

[0003] However, the traditional vacuum adsorption structure of the picking and placing mechanism is a rigid, fixed design. The adsorption holes cannot achieve circumferential rotation and adaptive fine-tuning alignment. Furthermore, the vibratory plate generates continuous micro-vibrations during continuous operation, which prevents the hook body, which has been sorted and is ready for picking in the feeding trough, from remaining completely still. There is always slight shaking and slight angle deviation, which makes it difficult for the fixed adsorption holes to accurately match the orientation of the square structure on the upper end of the hook. This easily leads to problems such as hole position misalignment and excessive alignment deviation. Not only does it easily cause the adsorption holes to fail to fit smoothly into the hook body and misaligned picking, but it also frequently causes picking jams. This greatly reduces the accuracy and success rate of picking up e-cigarette hooks, seriously affects the continuous operation stability of automated production lines, and significantly restricts the overall production and processing efficiency and product assembly quality of e-cigarettes. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention proposes an automated picking and placing mechanism for electronic cigarette hooks. This invention features a retractable and rotatable movable sleeve at the lower end of the adsorption cylinder. This allows the square adsorption hole inside the movable sleeve to better align with the upper end of the hook body as it rotates back and forth, thereby enabling the hook body to smoothly and quickly enter the adsorption hole to complete the picking action, making electronic cigarette production smoother and more stable.

[0014] The beneficial effects of this invention are as follows:

[0015] 1. This invention provides a retractable and rotatable movable sleeve at the lower end of the adsorption cylinder. This allows the square adsorption hole inside the movable sleeve to better align with the upper end of the hook body as it rotates back and forth. This enables the hook body to smoothly and quickly enter the adsorption hole to complete the material retrieval action, making the production of electronic cigarettes smoother and more stable.

[0016] 2. In this invention, the circular block can smoothly move down past the left and right offset blocks, allowing the ring to move down without rotating. The ring will drive the movable sleeve to move down, so that the movable sleeve moves down without rotating and is fitted onto the hook body. This avoids the hook body from rotating with the suction hole during the fitting process, making the hook body more stable in the feeding groove and making the process of the movable sleeve fitting onto the hook body more stable.

[0017] 3. After the movable sleeve is lowered and reset, the right rack presses against the upper surface of the ring again, further pressing the ring. This ensures that the movable sleeve will not move within the movable hole due to the adsorption force during the transfer of the hook body, thus preventing the adsorption hole from detaching from the hook body and improving the stability of the hook body's adsorption transfer.

Detailed Implementation

[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0032] like Figures 1 to 11 As shown, the present invention includes the following embodiments:

[0033] Example 1: An automated loading and unloading mechanism for electronic cigarette hooks includes a robot body 1 and a vibration feeding assembly 2 on one side of the robot body 1; the output end of the robot body 1 is fixedly connected to a vacuum adsorption assembly 3 and a camera assembly 4 via an integrated bracket 11 facing downwards; the vibration feeding assembly 2 vibrates and feeds the hook body 5 into a feeding trough 21; the output end of the robot body 1 can drive the vacuum adsorption assembly 3 to adsorb the hook body 5 in the feeding trough 21; the vacuum adsorption assembly 3 includes an inverted stepped adsorption cylinder 6; the adsorption cylinder 6 has a circular cavity 61 communicating with a suction source (not shown in the figure); the circular cavity 61 has a downwardly penetrating hole 6 for a movable sleeve 7 to be movably and sealingly connected. 2; The movable sleeve 7 is provided with suction holes 71 through its upper and lower sections, which are adapted to the cross-section of the upper half of the hook body 5; The circular cavity 61 is elastically connected to the upper and lower sections of a circular ring 8 that is fixedly connected to the movable sleeve 7; A circular block 82 is provided in the notch 81 at the edge of the circular ring 8; A left offset block 63 and a right offset block 64 are fixedly connected to the arc-shaped inner wall of the circular cavity 61 near the notch 81; An arc-shaped groove 65 is provided on the inner wall of the circular cavity 61 away from the left offset block 63 and the right offset block 64; The arc-shaped groove 65 is movably connected to the arc block 83 that is fixedly connected to the circular ring 8; The arc block 83 can move along the circumference and axial direction of the circular ring 8 within the arc-shaped groove 65; The left offset block 63 and the right offset block 64 are offset from the circular block 82 by half a body position in the circumferential direction.

[0034] In this embodiment, an annular guide groove 66 is provided at the upper end of the circular cavity 61; the upper inner wall of the annular guide groove 66 is abutted against the circular ring 8 by a first spring 67.

[0035] The vibratory feeding assembly 2 is a vibratory feeder that uses vibration for feeding. The hook body 5 in the vibratory feeding assembly 2 is fed under vibration (circular vibration), causing the hook body 5 to enter the feeding trough 21 under vibration (linear vibration). The bottom of the feeding trough 21 has a V-shaped structure, which is adapted to the bottom of the hook body 5. After the hook body 5 is in place in the feeding trough 21, the robot body 1 will move the vacuum adsorption assembly 3 and camera assembly 4 on the integrated support 11 in three-dimensional space. The camera assembly 4 will photograph the hook body 5 that needs to be adsorbed and picked up in the feeding trough 21. After determining whether it is in position, the vacuum adsorption component 3 is controlled to approach the hook body 5. After the adsorption cylinder 6 moves to directly above the corresponding hook body 5, the adsorption cylinder 6 is controlled to move downward. During the downward movement of the adsorption cylinder 6, the lower end will move closer to the hook body 5. The lower half of the adsorption cylinder 6 is stepped, and the outer diameter decreases from top to bottom. Therefore, the smaller volume of the lower end of the adsorption cylinder 6 can avoid the adjacent hook body 5 of the hook body 5 to be picked up. During the downward movement of the lower end of the adsorption cylinder 6, the lower end of the movable sleeve 7 will contact the upper end of the hook body 5 (pressing the hook body 5).

[0036] As the adsorption cylinder 6 continues to move downwards, the movable sleeve 7 moves upwards relative to the movable hole 62. The movable sleeve 7 drives the ring 8 to move upwards relative to the circular cavity 61. The ring 8 moves upwards against the elastic force of the first spring 67. The ring 8 drives the arc-shaped block 83 to move up and down within the arc-shaped groove 65. The circumferential thickness of the arc-shaped block 83 is less than the arc length of the arc-shaped groove 65. Therefore, the arc-shaped block 83 retains the arc-shaped freedom within the arc-shaped groove 65. During the axial movement of the ring 8 within the circular cavity 61, it drives the circular block 82 to alternately pass through the right offset block 64 and the left offset block 63. The number of right offset blocks 64 and left offset blocks 63 is unlimited, and they rotate counterclockwise or clockwise in the circumferential direction. The rings are arranged in a clockwise and counterclockwise pattern, alternating axially. The right-biased block 64 is circumferentially offset to the right relative to the circular block 82, and the left-biased block 63 is circumferentially offset to the left relative to the circular block 82. As the circular block 82 moves axially within the circular cavity 61 along with the circular ring 8, it rotates counterclockwise around the center of the circular ring 8 under the pressure of the right-biased block 64 (top view), and rotates clockwise around the center of the circular ring 8 under the pressure of the left-biased block 63 (top view). This causes the circular block 82 to drive the circular ring 8 to rotate back and forth. Since the first spring 67 abuts against the circular ring 8, it does not affect the rotation of the circular ring 8. During the rotation of the circular ring 8, the movable sleeve 7 rotates back and forth. As the movable sleeve 7 rotates back and forth, it causes the square suction hole 71 to rotate back and forth around the circumference of the movable sleeve 7. This allows the suction hole 71 to better align with the upper half of the square structure of the hook body 5 (achieving the purpose of alignment). After the suction hole 71 is aligned with the hook body 5, the first spring 67 will elastically return to its original position, thereby pushing the ring 8 to move downward. As the ring 8 moves downward, it causes the movable sleeve 7 to move downward, so that the movable sleeve 7 moves the suction hole 71 onto the upper half of the hook body 5. The movable sleeve 7 will then contact the lower half of the hook body 5. Then, the suction source (air pump) is activated, and the space inside the cavity 61 is suctioned using a hose, thus making the cavity... A negative pressure is generated at 61, and the suction hole 71 will form a negative pressure suction, thereby tightening the hook body 5. The suction cylinder 6 is controlled to move upward, driving the hook body 5 to move out of the feeding trough 21. The vibrating feeding component 2 will then vibrate to feed, thereby replenishing the space vacated in the feeding trough 21 with the hook body 5. The vacuum suction component 3 moves the hook body 5 to the feeding position along with the robot body 1. Before feeding, the feeding position can be determined by the camera component 4. After the hook body 5 moves to the feeding position, the suction source is released, causing the suction hole 71 to release the suction. The suction cylinder 6 moves upward and disengages from the hook body 5, and the above actions are repeated.

[0037] The present invention provides a retractable and rotatable movable sleeve 7 at the lower end of the adsorption cylinder 6, which allows the square adsorption hole 71 inside the movable sleeve 7 to be better aligned with the upper end of the hook body 5 as it rotates back and forth. This enables the hook body 5 to smoothly and quickly enter the adsorption hole 71 to complete the material picking action, making the production of electronic cigarettes smoother and more stable.

[0038] Example 2: The circular block 82 is inclined downward at the end away from the movable sleeve 7 with a slope 821; the notch 81 of the ring 8 is provided with a notch 84 corresponding to the circular block 82; the circular block 82 is slidably connected in the notch 84; the circular block 82 is connected to the bottom of the notch 84 by a notch spring 85.

[0039] In this embodiment, the cross-sectional shape of the circular block 82 is elliptical.

[0040] In this embodiment, the arc-shaped groove 65 is movably connected to the arc-shaped piece 651 along the circumference of the ring 8; the arc-shaped block 83 is located between the two arc-shaped pieces 651; the vertical length of the arc-shaped piece 651 is adapted to the vertical length of the arc-shaped groove 65; the arc-shaped piece 651 is connected to the vertical inner wall of the arc-shaped groove 65 by an arc-shaped spring 652; the elastic force of the arc-shaped spring 652 is greater than the elastic force of the missing spring 85.

[0041] As the ring 8 moves upward along the cavity 61, it drives the arc-shaped block 83 to move upward within the arc-shaped groove 65 along the gap between the two arc-shaped pieces 651. Under the elastic force of their respective arc-shaped springs 652, the arc-shaped pieces 651 maintain the arc-shaped block 83 in the middle position of the arc-shaped groove 65. This positions the circular block 82 between the left and right offset blocks 63 and 64 on the circumference of the ring 8. As the ring 8 moves the circular block 82 into contact with the left and right offset blocks 63 and 64, the inclined surface 821 on the circular block 82 faces downward. Therefore, during the upward movement, the inclined surface 821 on the circular block 82 will not contact the left and right offset blocks 63 and 64. It will not retract into the notched hole 84, thus causing the circular block 82 to squeeze against the left offset block 63 and the right offset block 64, forcing the circular block 82 to drive the ring 8 to rotate back and forth. During the rotation of the ring 8, the arc block 83 will alternately squeeze the arc plate 651, so that the arc springs 652 on the opposite side of the two arc plates 651 will be squeezed in turn. After the circular block 82 passes over one of the left offset blocks 63 or the right offset block 64 (both can be set as cylindrical structures), the arc block 83 will return to the arc-shaped groove 65 arc-shaped middle position under the action of the two arc springs 652. The circular block 82 will also return to the position between the left offset block 63 and the right offset block 64 on the circumferential direction of the ring 8.

[0042] During the reciprocating rotation of the ring 8, the ring 8 will drive the suction hole 71 on the movable sleeve 7 to rotate back and forth, realizing the alignment process of the hook body 5. After the hook body 5 is aligned with the suction hole 71, the reaction force of the first spring 67 will push the ring 8 downward. During the downward movement of the ring 8, the circular block 82 will also move downward. The circular block 82 is elliptical, so the circular block 82 will not rotate within the missing hole 84. The inclined surface 821 of the circular block 82 always remains inclined downward. The circular block 82 will contact the left offset block 63 or the right offset block 64 through the inclined surface 821, so that the inclined surface 821 of the circular block 82 is pressed and drives the circular block 82 to overcome the missing hole. Spring 85 retracts into notched hole 84. The elastic force of arc spring 652 is greater than that of notched spring 85, which makes arc block 83 stable in arc groove 65. Round block 82 can smoothly pass over left offset block 63 and right offset block 64, so that ring 8 moves down without rotating. Ring 8 will drive movable sleeve 7 to move down, so that movable sleeve 7 moves down without rotating and is fitted onto hook body 5. This avoids the situation where hook body 5 rotates with the rotation of adsorption hole 71 during the fitting process, making hook body 5 more stable in feeding groove 21, and making the process of movable sleeve 7 fitting onto hook body 5 more stable.

[0043] Example 3: The vacuum adsorption assembly 3 includes a buffer cylinder 9; the buffer cylinder 9 is located directly above the adsorption cylinder 6; the top of the buffer cylinder 9 is fixedly connected to the output end of the robot body 1; a buffer groove 91 is provided on the lower surface of the buffer cylinder 9; an upper annular groove 92 is provided on the upper inner wall of the buffer groove 91; the top of the adsorption cylinder 6 is movably connected to the buffer groove 91; the top of the adsorption cylinder 6 and the upper inner wall of the upper annular groove 92 are connected by a buffer spring 93; an anti-rotation groove 94 is provided in communication between the arc-shaped inner wall of the buffer groove 91 and the arc-shaped outer wall of the buffer cylinder 9; an anti-rotation rod 95 is movably connected up and down in the anti-rotation groove 94; the anti-rotation rod 95 is threadedly connected to the threaded hole on the arc-shaped outer wall of the adsorption cylinder 6.

[0044] In this embodiment, a pressing groove 68 is provided at the top of the adsorption cylinder 6; a pressing gear 681 is rotatably connected to the inner wall of the pressing groove 68; the pressing gear 681 meshes with a left rack 682 and a right rack 683 on the left and right sides respectively; the left rack 682 is fixedly connected to the upper inner wall of the buffer groove 91; the pressing groove 68 is connected to the circular cavity 61 through a right groove 684; the right groove 684 is slidably and sealingly connected to the right rack 683.

[0045] During the material handling process using the vacuum adsorption component 3, the buffer cylinder 9 moves along with the output end of the robot body 1 to directly above the corresponding hook body 5. As the buffer cylinder 9 moves downward, it drives the adsorption cylinder 6 downward. During the downward movement of the adsorption cylinder 6, it aligns the adsorption hole 71 in the movable sleeve 7 with the hook body 5. After the lower end of the movable sleeve 7 contacts the upper end of the hook body 5, as the buffer cylinder 9 continues to move downward, the contact between the lower end of the adsorption cylinder 6 and the hook body 5 acts on the buffer spring 93, causing the buffer spring 93 to be compressed. To buffer the vacuum adsorption assembly 3, the adsorption cylinder 6 moves axially within the buffer groove 91. The adsorption cylinder 6 drives the anti-rotation rod 95 to slide along the anti-rotation groove 94. The arc-shaped outer wall of the anti-rotation rod 95 can move with the anti-rotation groove 94 via a bearing (not labeled in the figure). As the upper end of the adsorption cylinder 6 retracts into the buffer groove 91, the left rack 682 meshes with the clamping gear 681, causing the clamping gear 681 to rotate counterclockwise. The clamping gear 681 then drives the right rack 683 to mesh, and the right rack 683 slides along the right groove 684. The right rack 683 gradually releases its pressure on the ring 8, allowing the movable sleeve 7 to move with the movable hole 62. As the movable sleeve 7 moves upward within the cavity 61, it works with the circular block 82, the left offset block 63, and the right offset block 64 to make the ring 8 rotate back and forth. The ring 8 will drive the suction hole 71 on the movable sleeve 7 to align with the hook body 5. After the suction hole 71 aligns with the hook body 5, the first spring 67 pushes the ring 8 downward to reset. The ring 8 will then drive the movable sleeve 7 downward to fit onto the upper half of the hook body 5. Then, the buffer cylinder 9 is moved upward to buffer... Spring 93 pushes the adsorption cylinder 6 away from the buffer groove 91 and towards the upper inner wall. Left rack 682 drives the clamping gear 681 to rotate clockwise. Right rack 683 moves down along right groove 684 under meshing. Right rack 683 presses against the upper surface of ring 8 again, achieving further clamping of ring 8. In this way, during the transfer of the adsorption hook body 5, the movable sleeve 7 will not move within the movable hole 62 due to the adsorption force, ensuring that the adsorption hole 71 will not detach from the hook body 5, thus improving the stability of the adsorption transfer of the hook body 5.

[0046] Example 4: The lower end of the adsorption cylinder 6 and the lower end of the movable sleeve 7 are respectively provided with a first guide surface 69 and a second guide surface 72; the first guide surface 69 and the second guide surface 72 form a guide cone surface that transitions to each other after the movable sleeve 7 moves to its limit position.

[0047] During the alignment process between the suction hole 71 at the lower end of the movable sleeve 7 and the hook body 5, the V-shaped structure at the lower end of the hook body 5 will not rotate within the feeding groove 21 at the bottom of the V-shaped groove. This ensures that the hook body 5 is aligned with the suction hole 71 under stable conditions. If the suction hole 71 of the movable sleeve 7 is not aligned with the upper end of the hook body 5, the movable sleeve 7 will move upward along the movable hole 62. The movable sleeve 7 will drive the second guide surface 72 to move upward, which, together with the first guide surface 69, forms a complete guide cone surface. This allows the upper end of the hook body 5 to smoothly enter the suction hole 71 under the guidance of the guide cone surface, thus making the material handling of the hook body 5 more stable. After the suction hole 71 of the movable sleeve 7 is aligned with the hook body 5, the movable sleeve 7 moves downward within the movable hole 62. The lower end of the movable sleeve 7 will re-contact the lower half of the hook body 5. The second guide surface 72 and the first guide surface 69 are misaligned, allowing more of the suction hole 71 to fit on the hook body 5. This makes the hook body 5 more stably adsorbed.

[0048] Example 5: The ring 8 is provided with a first through hole 86 and a second through hole 87 running through it vertically; the first through hole 86 is connected to the adsorption hole 71; the second through hole 87 is connected to the space below the ring 8 in the circular cavity 61.

[0049] The adsorption hole 71 is connected to the cavity 61 above the ring 8 through the first through hole 86. The cavities 61 on the upper and lower sides of the ring 8 are connected through the second through hole 87. In this way, the pressure in the cavities 61 on the upper and lower sides of the ring 8 is the same, which makes the ring 8 move more smoothly in the cavity 61.
