Description

Technical Field

[0001] This utility model relates to the field of automated production equipment for LED bulbs, and in particular to a lamp head alignment mechanism. Background Technology

[0002] LED bulbs are equipped with standardized lamp holders, which are used to establish a mechanical-electrical connection with the matching lamp base. When the lamp holder is screwed into the lamp base with a power interface such as a household power grid, a power supply circuit is formed. During the automated assembly of LED bulbs, the lamp holder needs to be precisely installed into the preset position on the lamp reflector, and the lamp reflector already has a lamp plate with two power cords pre-fixed on it.

[0003] The B22 type lamp holder is an industry-standard lamp holder with two wire holes at the end and a latching structure protruding on the side wall. During assembly, ensure that the two power wires of the lamp board pass through the corresponding wire holes, and then press the metal electrode contacts to the outside of the wire holes to achieve a reliable electrical connection between the lamp holder and the lamp board.

[0004] For the automated assembly of the B22 lamp head, a key requirement is to ensure precise alignment of the wire hole and the power cord using a precision positioning system. While current lamp heads can be automatically unloaded and kept upright by a vibratory feeder, the circumferential angular position of the two wire holes cannot be guaranteed. Therefore, a lamp head alignment mechanism needs to be designed to automatically adjust the lamp head to the designated position. Utility Model Content

[0005] The purpose of this utility model is to provide a lamp head alignment mechanism. The technical problem to be solved is how to achieve automatic rotation of the lamp head so that the two wire holes on the lamp head are at a set circumferential angle position.

[0006] To achieve the above objectives, the solution of this utility model is: a lamp head alignment mechanism for rotating and aligning the position of the lamp head, the lamp head being cylindrical with a latch protruding on the side of the lamp head, including a receiving plate, a driving component, a first elastic component, and a pressure head;

[0007] The top surface of the receiving plate is used for the lamp holder to be placed upright;

[0008] The drive unit is located above the receiving plate and can be raised, lowered, and rotated. The pressure head is slidably mounted on the bottom of the drive unit.

[0009] The first elastic element is located between the pressure head and the driving element, and the elasticity causes the pressure head to slide down relative to the driving element.

[0010] A relief cavity is formed in the center of the bottom surface of the pressure head, which is used for the top of the lamp head on the top surface of the receiving plate to extend into. An outer abutment edge is formed on the bottom surface of the pressure head around the relief cavity. The outer abutment edge is used to press down on the latch. A groove is provided on the outer abutment edge. The pressure head and the driving component rotate synchronously. When the pressure head rotates to the point where the groove is aligned with the latch, it can continue to slide down under the action of the first elastic component, so that the latch enters the groove, thereby driving the lamp head to rotate together with the pressure head.

[0011] Furthermore, the friction between the bottom surface of the lamp head and the top surface of the receiving plate is sufficient to ensure that when the pressure head rotates by pressing against the latch through the outer edge, the rotation of the pressure head will not cause the lamp head to rotate.

[0012] Furthermore, a limiting component is provided between the pressure head and the driving component. The limiting component limits the downward sliding limit position of the pressure head on the driving component. When the groove and the catch are aligned, the pressure head can slide down to the limit position, allowing the catch to enter the groove. At this time, there is a longitudinal gap between the top and bottom of the groove and the top of the catch.

[0013] Furthermore, the driving component can drive the pressure head to rise to a distance between it and the lamp head on the receiving plate, so as to make way for the lamp head.

[0014] Furthermore, the driving component and the pressure head are coaxial with the lamp head in the longitudinal direction, and the axis of rotation during rotation is the axis of the three components. The driving component can drive the pressure head to repeatedly stop rotating at a set angle.

[0015] Furthermore, the lamp holder is a B22 model lamp holder, with two protruding latches on the side of the lamp holder and two corresponding grooves formed on the outer edge.

[0016] Furthermore, it also includes a transplanting assembly and a lamp holder assembly, the lamp holder assembly including a positioning plate, a first lifting frame and a second lifting frame;

[0017] The transplanting assembly is used to pick up the lamp holders from the receiving plate and place them onto the positioning plate;

[0018] The top surface of the positioning plate is used to position the lamp head upright. The positioning plate is made up of multiple petals that are horizontally joined together. A wire passage is also formed between the petals. The bottom of the positioning plate is used for the lamp cup to enter. The lamp cup has a power cord extending upward. The positioning plate and the lamp cup below can be brought closer or further apart, so that the power cord can pass upward through the wire passage when they are close together.

[0019] The first lifting frame is located above the positioning plate, with a lifting mechanism and a downward-extending conduit for cable threading.

[0020] The second lifting frame is located above the positioning plate and connected to the first lifting frame. It can rise and fall with the first lifting frame and slide up and down relative to the first lifting frame. A second elastic element is provided between the second lifting frame and the first lifting frame. A pressing part is provided on the second lifting frame. After the second lifting frame descends with the first lifting frame, the pressing part can press down on the lamp head on the top surface of the positioning plate. When the first lifting frame continues to descend, the second elastic element can elastically deform. As the second lifting frame continues to descend, it can also drive the wire tube down to pass through the wire hole in the lamp head and connect to the wire channel to allow the power cord to enter. Each part can separate and open, and move away from below the lamp head to allow the second elastic element to spring down the second lifting frame, which in turn drives the lamp head pressed under the pressing part to spring down onto the lamp cup below the positioning plate.

[0021] Furthermore, the lamp holder assembly also includes a main lifting frame, which is raised and lowered. The positioning plate, the first lifting frame, and the second lifting frame are all installed on the main lifting frame so that they can rise and fall with the main lifting frame.

[0022] Furthermore, the threading channel formed by the splicing of each petal is shaped like an inverted funnel, expanding outward at the bottom and gradually contracting inward at the top.

[0023] Furthermore, the lamp holder is a B22 model lamp holder, with two power cords extending upward from the lamp cup. The segments are joined together to form two wire passages, allowing the two power cords to pass through upwards accordingly. Two wire passage tubes are also provided, each used to connect to the corresponding two wire passages.

[0024] Furthermore, a positioning cavity for the top of the lamp head to be inserted is formed in the center of the bottom surface of the crimping part, and a conical guide groove is provided on the outer edge of the bottom surface of the crimping part. The conical guide groove tapers inward from bottom to top, which is used to allow the latch on the lamp head to enter when the lamp head is inserted into the positioning cavity upward.

[0025] After adopting the above solution, the beneficial effects of this utility model are as follows: the top surface of the receiving plate is used for the lamp head to be placed upright. The driving component can drive the pressure head to descend. After descending, the top of the lamp head enters the relief cavity in the center of the bottom surface of the pressure head. The pressure head presses against the latch on the side wall of the lamp head through the outer edge of the relief cavity. Then, when the driving component continues to descend, the pressure head stops descending because it is blocked by the latch. At this time, the first elastic element will store energy. Then, the driving component drives the pressure head to rotate until the groove on the outer edge of the pressure head is aligned with the latch. Since the latch will no longer block the pressure head, the first elastic element will be released, driving the pressure head to descend further, so that the latch enters the groove. Then, the lamp head will rotate with the pressure head and can stop rotating with the pressure head at the set pressure head stopping angle, thereby realizing automatic adjustment of the lamp head to the specified position.

[0045] A lamp holder alignment mechanism, combined with Figure 1-16 As shown, the lamp head 1 is used for rotational alignment. The lamp head 1 is cylindrical, with a latch 2 protruding on its side. Specifically, the lamp head 1 is a standard B22 model lamp head. The lamp head 1 has two latches 2 protruding on its side, and two wire holes 25 are formed at the end of the lamp head 1. Of course, these are standard designs for B22 model lamp heads, and will not be described in detail in this embodiment. The lamp head alignment mechanism includes a receiving plate 3, a driving component 4, a first elastic component 5, and a pressure head 6. The top surface of the receiving plate 3 is used for the lamp head 1 to be placed upright, with the end of the lamp head 1 facing upwards. The driving component 4 is above the receiving plate 3 and can be raised, lowered, and rotated. Specifically, the driving component 4 is raised, lowered, and rotated under the drive of the driving component lifting cylinder 26 and the driving component rotating cylinder 27. The pressure head 6 is slidably mounted on the bottom of the driving component 4. The first elastic component 5 (only when...) Figure 3(As shown in the diagram, other views omitted) Located between the pressure head 6 and the driving member 4, the pressure head 6 is elastically driven to slide down relative to the driving member 4; a relief cavity 7 is formed in the center of the bottom surface of the pressure head 6, which is used for the top of the lamp head 1 on the top surface of the receiving plate 3 to extend into; an abutment outer edge 8 is formed on the bottom surface of the pressure head 6 around the relief cavity 7, which is used to press down on the latch 2; a groove 9 is provided on the abutment outer edge 8, specifically in this embodiment there are two grooves 9, corresponding to the two latches 2 on the lamp head, the groove width of the groove 9 is the same as the width of the latch 2. The pressure head 6 and the driving component 4 rotate synchronously. When the pressure head 6 rotates to the point where the groove 9 is aligned with the latch 2, it can continue to slide down under the action of the first elastic component 5, so that the latch 2 enters the groove 9, thereby driving the lamp head 1 to rotate together with the pressure head 6. The driving component and the pressure head are coaxial with the lamp head in the longitudinal direction, and the axis of rotation is the axis of the three. The driving component 4 can drive the pressure head 6 to repeatedly stop rotating at a set angle. In this embodiment, a rotary cylinder 27 is used to achieve this, so that the lamp head 1 can be in a set angle posture after stopping.

[0046] Specifically, in this embodiment, the vibratory feeder 28 discharges the material onto the receiving plate 3. The vibratory feeder 28 arranges the scattered parts into a row and sends them out, which is a conventional technique in the art. The structure and principle will not be described in detail in this embodiment. In this embodiment, the discharge port of the vibratory feeder 28 is connected to the receiving plate 3. The vibratory feeder 28 discharges the lamp head 1 upright onto the receiving plate 3. During this process, the driving component 4 can drive the pressure head 6 to rise to a vertical distance from the lamp head 1 on the receiving plate 3, allowing the lamp head 1 to move in and out. In a preferred embodiment, to allow the latch 2 to enter the groove 9 more quickly, the friction between the bottom surface of the lamp head 1 and the top surface of the receiving plate 3 is sufficient so that when the pressure head 6 rotates by pressing against the latch 2 through the outer edge 8, the rotation of the pressure head 6 will not cause the lamp head 1 to rotate. Of course, this requires a comprehensive design combining the elasticity of the first elastic element 5 and the descending stroke of the driving component 4 to achieve the above effect.

[0047] In a preferred embodiment, a limiting member is provided between the pressure head 6 and the driving member 4. The limiting member limits the downward sliding limit position of the pressure head 6 on the driving member 4. When the groove 9 and the latch 2 are aligned, the pressure head 6 can slide down to the limit position, allowing the latch 2 to enter the groove 9. At this time, there is a longitudinal gap 10 between the top and bottom of the groove 9 and the top of the latch 2. Thus, during the rotation of the pressure head 6 with the lamp head 1, the friction between the bottom surface of the lamp head 1 and the receiving plate 3 is minimized, avoiding damage to the lamp head 1 due to excessive friction. Specifically, the driving component 4 is column-shaped, and the pressure head 6 is fitted onto the bottom of its column shape and slides up and down. The first elastic component 5 is a spring, which is fitted onto the driving component 4 and pushes the pressure head 6 downward. The limiting component is a limiting pin 29 that is horizontally inserted and fixed on the driving component 4. The limiting pin 29 protrudes from the side wall of the driving component 4. A longitudinally extending long groove 30 is formed on the pressure head 6. The limiting pin 29 extends into the long groove 30 to limit the up and down sliding stroke of the pressure head 6 and to allow the pressure head 6 to rotate with the driving component 4.

[0048] It also includes a transplanting assembly 11 and a lamp holder assembly 12, the lamp holder assembly 12 including a positioning plate 13, a first lifting frame 14 and a second lifting frame 15;

[0049] The transplanting assembly 11 is used to pick up the lamp head 1 from the receiving plate 3 and place it onto the positioning plate 13. In this embodiment, the transplanting assembly 11 can also be used to position the lamp head 1. It has a transplanting gripper 31 with two claws. The two claws can move to the discharge port of the vibrating plate 28, so that the two claws are located on both sides of the discharge port. The two claws can move closer and further away from each other. When they move closer, a clamping space is formed between the two claws. The clamping space is connected to the discharge port on the side facing the discharge port. Then, the lamp head 1 discharged from the discharge port will directly enter between the two claws of the transplanting gripper 31. The transplanting gripper 31 is connected to a pushing cylinder 33. The pushing cylinder 33 is used to drive the transplanting gripper 31 to move laterally, so that the transplanting gripper 31 pushes the lamp head 1 between the two claws from the receiving plate 3 to the positioning plate 13.

[0050] The top surface of the positioning plate 13 is used for positioning the lamp holder 1 upright. Specifically, positioning is achieved by setting a positioning groove 34 on the top surface of the positioning plate 13 that matches the bottom contour of the lamp holder 1. The positioning groove 34 allows the bottom of the lamp holder 1 to fall into the positioning groove. The positioning plate 13 is formed by horizontally abutting multiple segments 16, and the positioning groove 34 is also formed after abutting. Specifically, in this embodiment, two segments 16 are provided, and a wire-passing channel 17 is formed between each segment 16. The bottom of the positioning plate 13 is used for the lamp cup 18 to enter. A power cord 19 extends upward from the lamp cup 18. In this embodiment, a B22 lamp holder is to be installed on the lamp cup 18, therefore two power cords 19 extend upward. Of course, corresponding to the two power cords 19, [further details are needed]. Two wire-passing channels 17 are provided, allowing the positioning plate 13 and the lower lamp holder 18 to move closer or further apart (specific structure will be given later) so that when they move closer, the corresponding power cord 19 passes upward through the corresponding wire-passing channel 17. The first lifting frame 14 is located above the positioning plate 13, is raised and lowered, and is provided with a downward-extending wire-passing tube 20. In this embodiment, two wire-passing tubes 20 are provided for the two power cords 19 corresponding to the B22 lamp holder. The second lifting frame 15 is located above the positioning plate 13 and is connected to the first lifting frame 14. It can rise and fall with the first lifting frame 14 and can also slide up and down relative to the first lifting frame 14. A second elastic element 38 is provided between the second lifting frame 15 and the first lifting frame 14 (only on the first lifting frame 14). Figure 11 (As shown in the diagram, other views omitted), the second lifting frame 15 is provided with a pressing part 21. After the second lifting frame 15 descends with the first lifting frame 14, the pressing part 21 can press down on the lamp head 1 on the top surface of the positioning plate 13. When the first lifting frame 14 continues to descend, the second lifting frame 15 stops descending, causing the second elastic member 38 to deform elastically. The first lifting frame 14 continues to descend until it drives the wire tube 20 down to pass through the wire hole on the lamp head 1 and connects with the wire channel 17 so that the power cord 19 can enter the wire tube 20. Each petal 16 can separate and open, and move away from below the lamp head 1, so that the second elastic member 38 can spring down the second lifting frame 15, driving the lamp head 1 pressed under the pressing part 21 to spring down onto the lamp cup 18 below the positioning plate 13.

[0051] In a specific embodiment, the lamp holder assembly 12 further includes a main lifting frame 22, which is pneumatically lifted. The positioning plate 13, the first lifting frame 14, and the second lifting frame 15 are all mounted on the main lifting frame 22 to move up and down with it. The two segments 16 of the positioning plate 13 are laterally slidably mounted on the main lifting frame 22, and are pneumatically driven to approach and separate. The first lifting frame 14 and the second lifting frame 15 are vertically slidably mounted on the main lifting frame 22. A first lifting frame drive cylinder 35 is provided between the first lifting frame 14 and the main lifting frame 22. The lifting frame drive cylinder 35 drives the first lifting frame 14 to rise and fall relative to the main lifting frame 22. The second lifting frame 15 is located below the first lifting frame 14. A guide rod 36 is fixed on the second lifting frame 15. The guide rod 36 extends longitudinally upward and passes through and engages with the first lifting frame 14. A limiting part 37 is radially protruding at the top of the guide rod 36. When the limiting part 37 abuts against the first lifting frame 14, it limits the second lifting frame 15 from falling further relative to the first lifting frame 14. The second elastic element 38 is a spring sleeved on the guide rod 36, which is compressed when the first lifting frame 14 and the second lifting frame 15 approach each other.

[0052] The specific working process of installing the lamp holder assembly 12 is as follows: First, the lamp holder 1 is placed on the positioning plate 13 for positioning, and the bottom end of the lamp holder 1 falls into the positioning groove 34. Then, the first lifting frame 14 is lowered, which drives the second lifting frame 15 to lower. When it falls to a certain height, the pressing part 21 on the second lifting frame 15 will press down on the lamp holder 1. Then, when the first lifting frame 14 continues to fall, the second lifting frame 15 will no longer move downward, and the second elastic element 38 will be compressed. The first lifting frame 14 will continue to fall until the conduit 20 is positioned. The wire 19 passes through the wire hole 25 on the lamp head 1 and connects to the wire channel 17. Then the main lifting frame 22 will descend, allowing the power cord 19 on the lamp cup 18 located below the positioning plate 13 to pass upward through the wire channel 17 and then continue into the wire tube 20. Then the two petals 16 of the positioning plate 13 separate, allowing the positioning plate 13 to be removed from under the lamp head 1. The crimping part 21 will quickly push the lamp head 1 down to the top of the lamp cup 18 under the elastic drive of the second elastic member 38, thereby completing the wire threading of the lamp head 1 and the docking assembly with the lamp cup 18.

[0053] In order to ensure that the power cord 19 can smoothly enter the cable channel 17, in a preferred embodiment, the cable channel 17 formed by the splicing of the segments 16 is an inverted funnel shape with the bottom expanding outward and the top gradually narrowing inward.

[0054] To prevent the lamp head 1 from shifting at an angle when moving from the receiving plate 3 to the positioning plate 13, which would affect subsequent wire threading, in a preferred embodiment, a positioning cavity 23 is formed in the center of the bottom surface of the crimping part 21 for the top of the lamp head 1 to be inserted. A tapered guide groove 24 is provided on the outer edge of the bottom surface of the crimping part 21. The tapered guide groove 24 tapers inward from bottom to top and is used to allow the latch 2 on the lamp head 1 to enter when the lamp head 1 is inserted into the positioning cavity 23.

[0055] The above description is only a preferred embodiment of this utility model and is not a limitation on 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.

Each part (16) can separate and open, and withdraw below the lamp head (1) to make the second elastic element (38) spring down the second lifting frame (15), and drive the lamp head (1) pressed under the crimping part (21) to spring down onto the lamp cup (18) below the positioning plate (13).

8. The lamp holder alignment mechanism as described in claim 7, characterized in that: The lamp holder assembly (12) also includes a main lifting frame (22), which is raised and lowered. The positioning plate (13), the first lifting frame (14), and the second lifting frame (15) are all installed on the main lifting frame (22) so that they can be raised and lowered with the main lifting frame (22).

9. The lamp holder alignment mechanism as described in claim 7, characterized in that: The threading channel (17) formed by the splicing of each petal (16) is an inverted funnel shape with the bottom expanding outward and the top gradually contracting inward; The lamp holder (1) is a B22 model lamp holder. The lamp cup (18) extends upward with two power cords (19). The segments (16) are joined together to form two wire passages (17) for the two power cords (19) to pass through upwards. There are also two wire tubes (20), which are used to connect to the corresponding two wire passages (17).

10. The lamp holder alignment mechanism as described in claim 7, characterized in that: The bottom surface of the crimping part (21) forms a positioning cavity (23) for the top of the lamp head (1) to be inserted. A tapered guide groove (24) is provided on the outer edge of the bottom surface of the crimping part (21). The tapered guide groove (24) is tapered from bottom to top and is used to allow the latch (2) on the lamp head (1) to enter when the lamp head (1) is inserted into the positioning cavity (23) upward.
