Description

Technical Field

[0001] This utility model relates to the field of automated equipment for bulb assembly, and in particular to a lamp cup flipping mechanism on an LED bulb assembly line. Background Technology

[0002] LED bulbs have a lamp holder mounted on one end and a light-transmitting bulb shell mounted on the other. Current automated LED bulb assembly equipment typically has a positioning seat to support the bulb, allowing it to move gradually between assembly stations to sequentially install the lamp holder and bulb shell onto the bulb. In some of these automated assembly machines, the lamp holder and bulb shell are installed from top to bottom onto the bulb. This necessitates flipping the bulb between the lamp holder and bulb shell installation stations. However, the shapes of the bulb holder end and the bulb shell end are different (e.g., some bulbs are conical). This causes the lifting stroke of the robotic arm used for flipping to differ from the descent stroke when returning the bulb to the positioning seat. Therefore, the robotic arm needs to compensate for this stroke difference. Traditional solutions require high-precision electrically controlled robotic arms with programmable lifting control to achieve stroke compensation through preset parameters, but this inevitably leads to a significant increase in equipment manufacturing costs.

[0003] The question of how to provide a simple, low-cost robotic arm capable of compensating for lifting strokes and flipping the lamp cups during LED bulb assembly remains to be solved. Utility Model Content

[0004] The purpose of this utility model is to provide a lamp cup flipping mechanism on an LED bulb assembly line. The technical problem to be solved is to provide a simple and low-cost robotic arm that can compensate for the lifting stroke and is used to flip the lamp cup during the LED bulb assembly process.

[0005] To achieve the above objectives, the solution of this utility model is: a lamp cup flipping mechanism on an LED bulb assembly line, used to pick up the lamp cup from the positioning seat, flip it over and put it back on the positioning seat, including a first sliding seat, a second sliding seat, a first telescopic cylinder, a second telescopic cylinder, a gripper, a gripper flipping drive mechanism and a gripper opening and closing drive mechanism.

[0006] The first sliding seat rises and falls under the action of the first telescopic cylinder;

[0007] The second sliding seat is located below the first sliding seat and is connected to the first sliding seat via a second telescopic cylinder. It moves up and down synchronously with the first sliding seat under the drive of the first telescopic cylinder, and also moves up and down relative to the first sliding seat under the drive of the second telescopic cylinder.

[0008] The gripper, gripper flipping drive mechanism, and gripper opening and closing drive mechanism are mounted on the second sliding seat. As the second sliding seat rises and falls, the two claws of the gripper extend laterally. Driven by the gripper opening and closing drive mechanism, the two claws move closer or further apart to grip or release the lamp cup. The gripper flipping drive mechanism is used to drive the gripper to flip so that the lamp cup gripped by the gripper is flipped up and down.

[0009] Furthermore, there is a height difference between the upward stroke of the lamp cup when it is lifted from the positioning seat and the downward stroke when the lamp cup is flipped over and put back into the positioning seat, and the extension stroke of the second telescopic cylinder or the first telescopic cylinder is consistent with the height difference.

[0010] Furthermore, the first or second telescopic cylinder, whose telescopic stroke is consistent with the height difference, is a telescopic stroke adjustable cylinder.

[0011] Furthermore, a column is also provided, and the first sliding seat and the second sliding seat are both slidably mounted on the column. The first telescopic cylinder is connected between the column and the first sliding seat.

[0012] Furthermore, the gripper flipping drive mechanism is a rotary cylinder with a turntable for pneumatic rotation on the side. The turntable rotates around its own laterally extending axis, and the gripper opening and closing drive mechanism is mounted on the turntable.

[0013] Furthermore, the two claw-shaped flaps 10 are centrally symmetrical about the rotation axis of the turntable 12.

[0014] Furthermore, the gripper opening and closing drive mechanism is a pneumatic finger.

[0015] Furthermore, the lamp cup is a cone shape that gradually tapers inward from the front to the back. The positioning seat is provided with a positioning cavity for the lamp cup to be inserted downward. The center of the positioning cavity gradually tapers inward from top to bottom so that the back of the lamp cup can be inserted downward for positioning. The outer ring of the top port of the positioning cavity is provided with a retaining edge so that the front of the lamp cup can be inserted downward for positioning.

[0016] The beneficial effects of this utility model after adopting the above solution are as follows: the first sliding seat rises and falls under the drive of the first telescopic cylinder; the second sliding seat is below the first sliding seat and connected to the first sliding seat through the second telescopic cylinder, so that it rises and falls synchronously with the first sliding seat under the drive of the first telescopic cylinder, and also rises and falls relative to the first sliding seat under the drive of the second telescopic cylinder; the gripper, the gripper flipping drive mechanism, and the gripper opening and closing drive mechanism are installed on the second sliding seat and rise and fall with the second sliding seat; the two claws of the gripper extend laterally, and under the drive of the gripper opening and closing drive mechanism... Two claws move closer or further apart to grip or release the lamp cup. A gripper flipping drive mechanism drives the grippers to flip, causing the lamp cup gripped by the grippers to turn upside down. By making the extension stroke of the second or first telescopic cylinder match the height difference when the lamp cup is lifted from the positioning seat, flipped, and then put back into the positioning seat, the height difference when the lamp cup is flipped and put back into the positioning seat can be compensated. This provides a simple and low-cost robotic arm that can compensate for the lifting stroke and is suitable for flipping lamp cups during LED bulb assembly. Attached Figure Description

Detailed Implementation

[0022] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Unless otherwise expressly defined, the use of directional terms such as "center," "lateral," "longitudinal," "horizontal," "vertical," "top," "bottom," "inner," "outer," "upper," "lower," "front," "rear," "left," "right," "clockwise," and "counterclockwise" in the claims, description, and accompanying drawings of this invention is merely for the convenience of describing the invention and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the specific scope of protection of this invention.

[0024] A lamp holder flipping mechanism on an LED bulb assembly line, such as Figures 1-4 As shown, this device is used to pick up the lamp cup 1 from the positioning seat 2, flip it over, and put it back on the positioning seat 2. The lamp cup 1 is a cone shape that gradually tapers inward from the front to the back. The positioning seat 2 is provided with a positioning cavity 13 for the lamp cup 1 to be inserted downward. The center of the positioning cavity 13 gradually tapers inward from top to bottom so that the back of the lamp cup 1 can be inserted downward for positioning. The outer ring of the top port of the positioning cavity 13 is provided with a baffle 14 for the lamp cup 1 to be inserted downward for positioning. Due to the shape of the lamp cup 1, there will be a height difference between the upward stroke when the lamp cup 1 is picked up from the positioning seat 2 and the downward stroke when the lamp cup 1 is flipped over and falls back to the positioning seat 2. However, the traditional pneumatic lifting robot is limited by the cylinder extension principle, and the upward and downward strokes are the same, so it is impossible to compensate for this height difference.

[0025] The lamp holder flipping mechanism on an LED bulb assembly line includes a first sliding seat 3, a second sliding seat 4, a first telescopic cylinder 5, a second telescopic cylinder 6, a gripper 7, a gripper flipping drive mechanism 8, and a gripper opening and closing drive mechanism 9. The first sliding seat 3 rises and falls under the drive of the first telescopic cylinder 5. The second sliding seat 4 is located below the first sliding seat 3 and is connected to the first sliding seat 3 via the second telescopic cylinder 6, so that it rises and falls synchronously with the first sliding seat 3 under the drive of the first telescopic cylinder 5, and also rises and falls relative to the first sliding seat 3 under the drive of the second telescopic cylinder 6. The gripper 7, the gripper flipping drive mechanism 8, and the gripper opening and closing drive mechanism 9 are mounted on the second sliding seat. 4. As the second sliding seat 4 rises and falls, the two claw segments 10 of the gripper 7 extend laterally. Driven by the gripper opening and closing drive mechanism 9, the two claw segments 10 move closer or further away to grip or release the lamp cup 1. The gripper flipping drive mechanism 8 is used to drive the gripper 7 to flip so that the lamp cup 1 gripped by the gripper 7 flips up and down. There is a height difference between the upward stroke of the lamp cup 1 when it is picked up from the positioning seat 2 and the downward stroke when the lamp cup 1 is flipped and put back into the positioning seat 2. The extension stroke of the second telescopic cylinder 6 or the first telescopic cylinder 5 is consistent with the height difference, so that while controlling the lifting and lowering with a low-cost cylinder, the height difference can also be compensated.

[0026] In order to adapt to different shapes of lamp cups (different shapes of lamp cups produce different height differences after being flipped), in a preferred embodiment, the first telescopic cylinder 5 or the second telescopic cylinder 6, whose extension stroke is consistent with the height difference, is a telescopic stroke adjustable cylinder. More specifically in this embodiment, the first telescopic cylinder 5 is a telescopic stroke adjustable cylinder. The extension and retraction stroke of the cylinder can be changed by manual adjustment (but the extension and retraction strokes are still consistent after adjustment). The specific internal structure is a conventional technique in the art and will not be described in detail in this embodiment.

[0027] In a more specific embodiment, a column 11 is also provided. The first sliding seat 3 and the second sliding seat 4 are both slidably mounted on the column 11. The first telescopic cylinder 5 is connected between the column 11 and the first sliding seat 3. Specifically, a mounting plate 15 extends laterally from the top of the column 11. The first telescopic cylinder 5 has a first cylinder 16 and a first piston rod 17. The first cylinder 16 is fixed on the mounting plate 15, and the first piston rod 17 extends downward through the mounting plate 15, with its end fixed to the first sliding seat 3. The second telescopic cylinder 6 has a second cylinder 18 and a second piston rod 19. The second cylinder 18 is fixed on the first sliding seat 3, and the second piston rod 19 extends downward, with its end fixed to the second sliding seat 4.

[0028] The gripper flipping drive mechanism 8 is a rotary cylinder, and a turntable 12 for pneumatic rotation is provided on the side. The turntable 12 rotates around its own laterally extending axis, and the gripper opening and closing drive mechanism 9 is installed on the turntable 12.

[0029] The gripper opening and closing drive mechanism 9 is a pneumatic finger. One end is used for mounting the two claw segments 10 of the gripper 7, and the other end is used to fix it on the turntable 12, so that the two claw segments 10 are symmetrical about the rotation axis of the turntable 12.

[0030] The above description is only a preferred embodiment of this utility model and is not intended to limit the design of this case. All equivalent changes made based on the key design of this case shall fall within the protection scope of this case.
