Description

Technical Field

[0001] The invention relates to LED lamp bead packaging technology, and in particular to an LED lamp bead packaging transfer device. Background Art

[0002] In the production process of LED lamp beads, the transfer of package parts is a crucial link. The traditional transfer method usually adopts negative pressure adsorption, and the package parts are adsorbed by negative pressure suction cups and moved to the next station. However, in the actual operation process, the package parts may be offset during adsorption, resulting in the package parts not being accurately adsorbed at the predetermined position. In the subsequent processing process, manual or auxiliary devices are required to reposition the package parts, which not only increases the processing cost, but also seriously affects the production efficiency.

[0003] A Chinese invention patent with authorization announcement number CN117727679B discloses an LED lamp bead packaging and welding device. When placing the lamp bead through an adsorption-type boss, the lamp bead is placed on the adsorption-type boss with its corner facing the right angle of the right-angle baffle, and is abutted against the inner side of the right-angle baffle. The position of the lamp bead is initially fixed by negative pressure adsorption, thereby ensuring the accuracy of the position of the lamp bead when it is fixed. Subsequently, the position of the lamp bead is fixed by flipping the elastic limiting structure and abutting against the other two sides of the lamp bead. The LED lamp bead packaging and welding device transfers and fixes the lamp bead through negative pressure adsorption. The lamp bead is pushed and adjusted by flipping the elastic limiting structure. However, during the pushing process, the lamp bead may fall off due to the excessive movement of the lamp bead. Similarly, when the remaining packaged components are transferred in this way, the packaged components may fall off, resulting in the need for secondary intervention by humans or equipment, thereby reducing processing efficiency.

[0034] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0035] Embodiment 1:

[0036] See also Figures 1 to 4 , an LED lamp bead package transfer device, including a mechanical arm 1, a negative pressure suction cup 2 and an air pipe 3, the material of the air pipe 3 is a hard material, the negative pressure suction cup 2 is used to absorb the package, the negative pressure suction cup 2 is arranged on the execution end side of the mechanical arm 1, the top of the negative pressure suction cup 2 is connected to the bottom of the air pipe 3, the top of the air pipe 3 is connected to the external negative pressure generator through a pipeline, and also includes: A support 4, B support 5, positioning mechanism 6, receiving mechanism 7 and mobile driving mechanism 8;

[0037] One side of the A support member 4 is fixedly connected to the execution end of the robot arm 1 through a bracket;

[0038] The B support member 5 is arranged at the bottom of the A support member 4, and the positioning mechanism 6 is installed on the B support member 5, and the positioning mechanism 6 is used to adjust the position of the package adsorbed by the negative pressure suction cup 2;

[0039] One side of the B support member 5 is connected to a moving driving mechanism 8 for driving the B support member 5 to move along the length direction of the trachea 3;

[0040] The receiving mechanism 7 is installed on the B support member 5, and the receiving mechanism 7 includes a receiving member 71, a support column 72 and a rotation driving mechanism 73. The bottom end of the support column 72 is connected to the receiving member 71, and the upper end of the support column 72 is connected to the B support member 5. The receiving member 71 can rotate around the axis of the support column 72 to the A position and the B position. The A position is located at the bottom of the negative pressure suction cup 2, and the B position is located at the side of the negative pressure suction cup 2. One side of the receiving member 71 is connected to the rotation driving mechanism 73 which can drive the receiving member 71 to move to the A position or the B position.

[0041] In the existing practice, when transferring LED lamp bead packages, negative pressure adsorption is usually used. However, when adsorbing the packages, the packages may deviate from the predetermined adsorption points, resulting in a position shift of the packages. When the packages are transferred to the next station, manual or auxiliary devices are required to reposition the packages, which reduces processing efficiency.

[0042] To this end, the present application provides a positioning mechanism 6, and installs the positioning mechanism 6 on the B support 5. The position of the package adsorbed by the negative pressure suction cup 2 is adjusted by the positioning mechanism 6, and the position of the package is adjusted during the transfer of the package to improve the processing efficiency, and the B support 5 is driven by the mobile driving mechanism 8 to move along the length direction of the trachea 3. The B support 5 can drive the positioning mechanism 6 and the receiving mechanism 7 to move through the B support 5, so that the negative pressure suction cup 2 moves relative to the B support 5, so that the B support 5, the positioning mechanism 6 and the receiving mechanism 7 do not hinder the negative pressure suction cup 2 from adsorbing the package. Since the package is adsorbed by the negative pressure suction cup 2, when the position of the package is adjusted, there is a possibility that the package deviates from the predetermined adsorption When the distance between the points is too large, the package will break away from the adsorption of the negative pressure suction cup 2 and fall off when the package is pushed to adjust its position. For this reason, the present application is provided with a receiving mechanism 7. When the position of the package is adjusted by the positioning mechanism 6, the rotating drive mechanism 73 drives the receiving member 71 to rotate around the axis of the support column 72 to the bottom of the negative pressure suction cup 2 to receive the package. The package dropped on the receiving member 71 can be driven by the moving drive mechanism 8 to move the B support member 5, and the negative pressure suction cup 2 moves downward relative to the B support member 5, and the negative pressure suction cup 2 adsorbs the package again, thereby avoiding the situation where the package deviates from the predetermined adsorption point by a large distance when the package is pushed and breaks away from the adsorption of the negative pressure suction cup 2 and falls to the ground or other equipment.

[0043] In one embodiment of the present invention, a through hole is opened in the middle of the A support member 4, and the inner wall of the through hole is fixedly connected to the outer wall of the trachea 3, and the A support member 4 can be fixed to the trachea 3 by bolts.

[0044] See also Figures 4 to 6 In one embodiment of the present invention, the positioning mechanism 6 includes an A driving assembly and four positioning members 61, the four positioning members 61 are evenly distributed on the circumference of the negative pressure suction cup 2, one side of the four positioning members 61 is respectively connected to the A driving assembly, and the A driving assembly is used to drive the four positioning members 61 to move radially along the trachea 3 respectively;

[0045] The four positioning members 61 are driven by the A driving assembly to move radially along the air pipe 3. When the package deviates to one side of one of the positioning members 61, the positioning member 61 pushes the package to reposition the package.

[0046] In one embodiment of the present invention, the A driving assembly includes a turntable 62, a gear ring 63, a gear 64, an A rotating driving member 65 and four push rods 66. The bottom ends of the four push rods 66 are respectively connected to the adjacent positioning members 61. The turntable 62 is rotatably mounted on the B support member 5. The axis of the turntable 62 is colinear with the axis of the trachea 3. Four inclined grooves 67 are opened on the turntable 62, and the four inclined grooves 67 are arranged in a circular array with the axis of the turntable 62 as the center line. The outer side walls of the four push rods 66 are respectively connected to the adjacent inclined grooves 6 7 is slidably connected to the inner wall, four slide grooves are arranged at the bottom end of the B support member 5, and the inner walls of the four slide grooves are slidably connected to the push rods 66 adjacent thereto respectively, and the ring gear 63 is fixedly sleeved on the outside of the turntable 62, and one side of the ring gear 63 is meshed with the gear 64, and one side of the gear 64 is connected to the A rotation driving member 65 for driving the gear 64 to rotate around its own axis, and the A rotation driving member 65 is a rotary cylinder or a motor, and the gear 64 is fixedly sleeved on the outside of the output shaft of the A rotation driving member 65, and the A rotation driving member 65 is fixedly installed on the B support member 5;

[0047] A rotary drive member 65 drives the gear 64 to rotate, and the gear 64 drives the turntable 62 to rotate through the ring gear 63. The extension line of the length direction of the slide groove intersects with the axis of the trachea 3. Under the restriction of the slide groove on the push rod 66, when the turntable 62 rotates, the inner wall of the inclined groove 67 pushes the push rod 66 to move along the inner wall of the slide groove, and the push rod 66 drives the positioning member 61 to move, thereby realizing the radial movement of the positioning member 61 along the trachea 3.

[0048] See also Figures 4 to 5 In one embodiment of the present invention, the positioning member 61 includes a pushing plate 611, a guide rail 612 and a screw rod 613. The top of the pushing plate 611 is slidably connected to the guide rail 612, the upper surface of the guide rail 612 is fixedly connected to the push rod 66 adjacent thereto, the outer side wall of the screw rod 613 is fixedly connected to the pushing plate 611, and both ends of the screw rod 613 are rotatably connected to the guide rail 612 respectively;

[0049] Since different packages have different specifications and models, such as packages for side-light-emitting devices and packages for front-light-emitting devices, most packages are in the shape of a rectangular parallelepiped. By rotating the screw 613, the screw 613 drives the pushing plate 611 to move along the inner wall of the guide rail 612, so that the position of the pushing plate 611 can be pre-adjusted, so that the four pushing plates 611 can better push the package to adjust the position of the package.

[0050] See also Figure 2 , Figures 7 to 9In one embodiment of the present invention, the rotary drive mechanism 73 includes an A sleeve 731, a push rod 732, a fixing member 733, a B sleeve 734 and a limiting member. The A sleeve 731 is fixedly sleeved on the outer side of the upper end of the support column 72, and the outer side wall of the support column 72 is rotatably connected to the B support member 5. A spiral groove 730 is provided on the outer side of the A sleeve 731, and one end of the push rod 732 is slidably connected to the inner wall of the spiral groove 730, and the other end of the push rod 732 is fixedly connected to the fixing member 733, and the top end of the fixing member 733 is fixedly connected to the A support member 4, the B sleeve 734 is sleeved on the outer side of the support column 72, and the top end of the B sleeve 734 is rotatably connected to the A support member 4, and the bottom end of the B sleeve 734 is fixedly connected to the receiving member 71, and the limiting member is installed on the B sleeve 734;

[0051] The limiting member can be switched between a limiting state and a non-limiting state. When the limiting member is in the limiting state, the limiting member prevents the support column 72 from rotating relative to the B sleeve 734 around the axis of the B sleeve 734, and does not prevent the B sleeve 734 from rotating relative to the B support member 5 around the axis of the B sleeve 734; when the limiting member is in the non-limiting state, the limiting member prevents the B sleeve 734 from rotating relative to the B support member 5 around the axis of the B sleeve 734, and does not prevent the support column 72 from rotating relative to the B sleeve 734 around the axis of the B sleeve 734;

[0052] Before the negative pressure suction cup 2 is used to absorb and transfer the package, the mobile driving mechanism 8 drives the B support member 5 to move upward relative to the negative pressure suction cup 2 to avoid interference from the positioning mechanism 6. At this time, the receiving member 71 is in the B position. After the negative pressure suction cup 2 absorbs the package, the execution end of the robot arm 1 moves to transfer the package. During this process, the mobile driving mechanism 8 drives the B support member 5 to move downward relative to the negative pressure suction cup 2, and the positioning mechanism 6 adjusts the position of the package. When the B support member 5 moves downward relative to the negative pressure suction cup 2, the B support member 5 moves downward relative to the A support member 4. Due to the fixing member 733 is fixed on the A support member 4, and the push rod 732 slides along the inner wall of the spiral groove 730. The push rod 732 pushes the inner wall of the spiral groove 730 to drive the support column 72 to rotate. At this time, the control limiter is in a restricted state, so that the support column 72 can drive the B sleeve 734 to rotate through the limiter, and the B sleeve 734 drives the receiving member 71 to rotate to the A position, that is, the receiving member 71 rotates to the bottom of the negative pressure suction cup 2. Similarly, when the mobile driving mechanism 8 drives the B support member 5 to move upward relative to the negative pressure suction cup 2, the B sleeve 734 can drive the receiving member 71 to rotate to the B position;

[0053] When the package falls onto the receiving part 71, the negative pressure suction cup 2 needs to re-absorb the package. At this time, the control limiting part is in a non-restrictive state. When the support column 72 rotates, it cannot drive the B sleeve 734 to rotate, and the B sleeve 734 cannot rotate relative to the B support part 5, so that the receiving part 71 is fixed to the bottom of the negative pressure suction cup 2, so that the negative pressure suction cup 2 can re-absorb the package.

[0054] In one embodiment of the present invention, the limiting member includes a fixing frame 735, a positioning rod 736, a C sleeve 737, a positioning plate 738 and a B driving assembly. The C sleeve 737 is fixedly sleeved on the outside of the support column 72, and the top of the positioning plate 738 is fixedly connected to the B support member 5. The C sleeve 737 and the positioning plate 738 are both provided with a plug hole for inserting the end of the positioning rod 736. The outside of the positioning rod 736 is slidably connected to the B sleeve 734. One side of the fixing frame 735 is fixedly connected to the positioning rod 736, and the other side of the fixing frame 735 is connected to the B driving assembly for driving the fixing frame 735 to move axially along the positioning rod 736.

[0055] When the fixing frame 735 is driven to move by the B driving assembly, the fixing frame 735 drives the positioning rod 736 to move. When the positioning rod 736 is partially inserted into the insertion hole on the C sleeve 737 and the positioning rod 736 is not in the insertion hole on the positioning plate 738, the limiting member is in a limiting state; when the positioning rod 736 is partially inserted into the insertion hole on the positioning plate 738 and the positioning rod 736 is not in the insertion hole on the C sleeve 737, the limiting member is in a non-restricting state.

[0056] In one embodiment of the present invention, the B driving component is a B telescopic driving component 739, the moving end of the B telescopic driving component 739 is fixedly connected to the fixed frame 735, the fixed end of the B telescopic driving component 739 is fixedly connected to the B sleeve 734 through a bracket, the B telescopic driving component 739 is a telescopic cylinder or a hydraulic cylinder, and when the moving end of the B telescopic driving component 739 moves, it drives the fixed frame 735 to move, and the fixed frame 735 drives the positioning rod 736 to move.

[0057] See also Figure 3 to Figure 4 In one embodiment of the present invention, the mobile driving mechanism 8 includes a guide rod 81 and an A telescopic driving member 82, the A telescopic driving member 82 is a telescopic cylinder or a hydraulic cylinder, the fixed end of the A telescopic driving member 82 is fixedly connected to the A support member 4, the moving end of the A telescopic driving member 82 penetrates the A support member 4 and is fixedly connected to the B support member 5, the bottom end of the guide rod 81 is fixedly connected to the B support member 5, the top end of the guide rod 81 penetrates the A support member 4 and the outer wall of the guide rod 81 is slidably connected to the A support member 4, under the guidance of the guide rod 81, the moving end of the A telescopic driving member 82 moves to drive the B support member 5 to move.
