A lamp cap threading mechanism

Abstract

This utility model discloses a lamp holder wiring mechanism. The top surface of the positioning plate is used to position the lamp holder upright. The positioning plate is composed of multiple segments laterally joined together, forming a wiring channel between adjacent segments. The lamp holder enters from below the positioning plate. After the positioning plate approaches the lamp holder, the power cord of the lamp holder passes upward through the wiring channel. A first lifting frame is provided with a downward-extending wiring tube. A second lifting frame is provided between the first and second lifting frames. The second lifting frame has a pressing part. After the second lifting frame descends with the first lifting frame, the pressing part presses down on the lamp holder on the top surface of the positioning plate. As the first lifting frame continues to descend, the elastic element deforms elastically, and the wiring tube descends to pass through the wiring hole in the lamp holder and aligns with the wiring channel, allowing the power cord to enter. When the segments separate and retract below the lamp holder, the elastic element springs down the second lifting frame, causing the lamp holder below the pressing part to spring down onto the lamp holder. This achieves automatic wiring of the power cord from the lamp holder through the wiring hole in the lamp holder.

Description

Technical Field

[0001] This utility model relates to the technical field of automatic bulb assembly equipment, and in particular to a lamp holder threading mechanism. Background Technology

[0002] LED bulbs are equipped with standardized lamp holders, which establish a mechanical-electrical connection with the matching lamp base. When the lamp holder is screwed into a 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. The lamp reflector already has a lamp plate with a power cord pre-fixed on it, and the lamp holder has a wire-passing hole. During assembly, the power cord needs to be precisely passed through this hole. Because the power cord has a certain degree of flexibility and is prone to bending, causing its end position to shift, achieving automated wire-passing through the hole presents a challenge.

[0003] There is a current need for a lamp holder wiring mechanism to automatically thread the power cord from the lamp holder through the wiring hole on the lamp holder during the assembly process of the lamp holder and lamp reflector. Utility Model Content

[0004] The purpose of this utility model is to provide a lamp holder wire threading mechanism, and the technical problem to be solved is how to automatically thread the power cord on the lamp holder through the threading hole on the lamp holder during the assembly process of the lamp holder and the lamp cup.

[0005] To achieve the above objectives, the solution of this utility model is: a lamp holder wire threading mechanism, including a positioning plate, a first lifting frame, and a second lifting frame;

[0006] 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. The positioning plate also forms a wire passage. The wire passage is formed between adjacent petals after the petals are joined together. 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 moved closer or further apart, so that the power cord can pass upward through the wire passage when they are close together.

[0007] The first lifting frame is located above the positioning plate, with a lifting mechanism and a downward-extending conduit for cable threading.

[0008] 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. An 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. Then, when the first lifting frame continues to descend, the elastic element can elastically deform, so that the first lifting frame continues to descend relative to the second lifting frame, thereby driving the cable tube down to pass through the cable hole in the lamp head and connect to the cable channel to allow the power cord to enter. Each part can separate and open, and withdraw below the lamp head, so that the elastic element can spring down the second lifting frame, driving the lamp head pressed under the pressing part to spring down onto the lamp cup below the positioning plate.

[0009] Furthermore, the top surface of the positioning plate is provided with a positioning groove that matches the contour of the bottom end of the lamp head, and the positioning groove allows the bottom end of the lamp head to fall into the positioning.

[0010] Furthermore, the bottom of the threading channel formed by the splicing of each segment is shaped like an inverted funnel, with the bottom expanding outwards and the top gradually narrowing inwards, to guide the power line as it is threaded upwards.

[0011] Furthermore, the threading channel formed by the splicing of each segment is funnel-shaped with the bottom end narrowing inward and the top end gradually widening outward, so as to guide the insertion of the threading tube when the threading tubes are connected.

[0012] Furthermore, the number of wire holes on the lamp head, the number of wire channels between each segment, and the number of wire tubes are all consistent with the number of power lines extending upward from the lamp cup, so that each power line can pass through a wire channel and then be inserted into a wire tube connected to that wire channel.

[0013] Furthermore, the lamp head sidewall has a protruding latch, and a positioning cavity for the top of the lamp head to be inserted is formed in the center of the bottom surface of the pressing part. A conical guide groove is provided on the outer edge of the bottom surface of the pressing part. The conical guide groove tapers inward from bottom to top and is used to allow the latch on the lamp head to enter when the lamp head is inserted into the positioning cavity upward, so as to position the lamp head.

[0014] Furthermore, it also includes a main lifting frame, a lifting mechanism for the main lifting frame, and a positioning plate, a first lifting frame, and a second lifting frame, all of which are installed on the main lifting frame so that they can rise and fall with the main lifting frame. The positioning plate rises and falls with the main lifting frame, allowing the positioning plate to move closer to or further away from the lamp cup below.

[0015] Furthermore, a first lifting frame drive cylinder is provided between the first lifting frame and the main lifting frame. The first lifting frame drive cylinder drives the first lifting frame to rise and fall relative to the main lifting frame. The second lifting frame is located below the first lifting frame. A guide rod is fixed on the second lifting frame. The guide rod extends longitudinally upward and passes through and engages with the first lifting frame. A limiting part is radially protruding at the top of the guide rod. When the limiting part abuts against the first lifting frame, it limits the second lifting frame from falling further relative to the first lifting frame. The second elastic element is a spring sleeved on the guide rod, which is compressed when the first lifting frame and the second lifting frame approach each other.

[0016] The beneficial effects of this utility model after adopting the above solution are as follows: After the positioning plates are assembled, the top surface is used for the lamp head to be upright and positioned. The second lifting frame is provided with a pressing part. 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. Then, when the first lifting frame continues to descend, the elastic element between the second lifting frame and the first lifting frame elastically deforms, allowing the first lifting frame to continue to descend relative to the second lifting frame, so as to drive the wire guide tube on the first lifting frame to descend to the wire guide hole in the lamp head and then connect with the wire guide tube. On the wire channel, the area below the positioning plate is used for the lamp cup to enter. The lamp cup extends upwards with a power cord. The positioning plate and the lamp cup below can move closer or further apart, so that when they move closer, the power cord passes upward through the wire channel and enters the wire tube that is connected to the wire channel. Each part can separate and open, and move away from below the lamp head, so that the elastic element can pop down the second lifting frame, which will drive the lamp head pressed under the crimping part to pop down onto the lamp cup below the positioning plate. This realizes that during the assembly of the lamp head and the lamp cup, the power cord on the lamp cup is automatically passed through the wire hole on the lamp head. Attached Figure Description

[0029] A lamp holder wiring mechanism, such as Figure 1-9 As shown, it includes a positioning plate 1, a first lifting frame 2, and a second lifting frame 3;

[0030] The top surface of the positioning plate 1 is used for positioning the lamp head 4 upright. The top of the lamp head 4 has a wire hole 13. Specifically, positioning is achieved by setting a positioning groove 12 on the top surface of the positioning plate 1 that matches the bottom contour of the lamp head 4. The positioning groove 12 allows the bottom of the lamp head 4 to fall into the positioning. The positioning plate 1 is formed by horizontally assembling multiple petals 5. The positioning groove 12 is also formed after assembly. Specifically, in this embodiment, there are two petals 5. After the petals 5 are assembled, the seam between adjacent petals 5 is also assembled to form a wire passage 6. The bottom of the positioning plate 1 is used for the lamp cup 7 to enter. The lamp cup 7 has a power line 8 extending upward. The positioning plate 1 and the lamp cup 7 below can move closer or further apart vertically (the specific structure is given later) so that when they move closer, the corresponding power line 8 passes upward through the corresponding wire passage 6. The first lifting frame 2 is above the positioning plate 1, is set to move up and down, and is provided with a downward extension The number of wire holes 13 on the lamp holder 4, the number of wire channels 6 between each segment 5, and the number of wire tubes 9 are all consistent with the number of power cords 8 extending upward from the lamp cup 7, so that each power cord 8 can pass through a wire channel 6 and then through a wire tube 9 connected to that wire channel 6, and each wire tube 9 can pass through a corresponding wire hole 13. In this embodiment, the lamp cup 7 is to be installed with a B22 lamp holder (with two wire holes 13), so the lamp cup 7 has two power cords 8 extending upward, and two wire channels 6 and two wire tubes 9 are provided for the two power cords 8; the second lifting frame 3 is above the positioning plate 1 and connected to the first lifting frame 2, and can rise and fall with the first lifting frame 2, and can also slide up and down relative to the first lifting frame 2. An elastic element 10 is provided between the second lifting frame 3 and the first lifting frame 2 (only on the first lifting frame 2). Figure 3 and Figure 5 As shown in the diagram, the second lifting frame 3 is provided with a pressing part 11. After the second lifting frame 3 descends with the first lifting frame 2, the pressing part 11 can press down on the lamp head 4 on the top surface of the positioning plate 1. When the first lifting frame 2 continues to descend, the second lifting frame 3 stops descending, causing the elastic element 10 to elastically deform. Figure 3 Before deformation, Figure 5 After deformation, the conduit 9 is lowered to pass through the conduit hole on the lamp head 4 and then docks with the conduit channel 6 to allow the power cord 8 to enter. Each petal 5 can separate and open, and move away from below the lamp head 4 to allow the elastic element 10 to spring down the second lifting frame 3, which in turn causes the lamp head 4, which is pressed below the pressing part 11, to spring down onto the lamp cup 7 below the positioning plate 1.

[0031] In a specific embodiment, it also includes a main lifting frame 18, which is pneumatically lifted. The positioning plate 1, the first lifting frame 2, and the second lifting frame 3 are all mounted on the main lifting frame 18 so that they can rise and fall with the main lifting frame 18. The two segments 5 of the positioning plate 1 are laterally slidably mounted on the main lifting frame 18, and are pneumatically driven to approach and separate. The first lifting frame 2 and the second lifting frame 3 are both vertically slidably mounted on the main lifting frame 18. A first lifting frame drive cylinder 19 is provided between the first lifting frame 2 and the main lifting frame 18. The drive cylinder 19 drives the first lifting frame 2 to rise and fall relative to the main lifting frame 18. The second lifting frame 3 is located below the first lifting frame 2. A guide rod 20 is fixed on the second lifting frame 3. The guide rod 20 extends longitudinally upward and passes through and engages with the first lifting frame 2. A limiting part 21 is radially protruding at the top of the guide rod 20. When the limiting part 21 abuts against the first lifting frame 2, it limits the second lifting frame 3 from falling further relative to the first lifting frame 2. The elastic element 10 is a spring sleeved on the guide rod 20, which is compressed when the first lifting frame 2 and the second lifting frame 3 approach each other.

[0032] The specific working process is as follows: First, the lamp head 4 is placed on the positioning plate 1 for positioning, and the bottom end of the lamp head 4 falls into the positioning groove 12. Then, the first lifting frame 2 is lowered, which drives the second lifting frame 3 to lower. When it falls to a certain height, the pressing part 11 on the second lifting frame 3 will press down on the lamp head 4. Then, when the first lifting frame 2 continues to fall, the second lifting frame 3 will no longer move downward, and the elastic element 10 will be compressed. The first lifting frame 2 will continue to fall until the wire tube 9 passes through the wire hole 1 on the lamp head 4. 3. Connect to the wiring channel 6, and then the main lifting frame 18 will descend, so that the power cord 8 on the lamp cup 7 located below the positioning plate 1 passes upward through the wiring channel 6, and then continues into the wiring tube 9. Then the two petals 5 of the positioning plate 1 separate, so that the positioning plate 1 is removed from below the lamp head 4. Under the elastic drive of the elastic member 10, the crimping part 11 will quickly push the lamp head 4 down to the top of the lamp cup 7, so that the lamp head 4 is installed on the lamp cup from top to bottom, thereby completing the wiring of the lamp head 4 and the docking assembly with the lamp cup 7.

[0033] In order to ensure that the power cord 8 can smoothly enter the cable passage 6, in a preferred embodiment, the bottom of the cable passage 6 formed by the splicing of the segments 5 is an inverted funnel with the bottom end expanding outward and the top end gradually narrowing inward, so as to guide the power cord 8 as it is inserted upward.

[0034] In order to ensure that the conduit 9 can be accurately connected to the conduit channel 6, in a preferred embodiment, the top of the conduit channel 6 formed by the splicing of each lobe 5 is funnel-shaped with the bottom end narrowing inward and the top end gradually widening outward, so as to guide the conduit 9 when it is connected.

[0035] To prevent the lamp head 4 from shifting at an angle when placed on the positioning plate 1, which would affect subsequent wiring, in a preferred embodiment, a positioning cavity 15 is formed in the center of the bottom surface of the crimping part 11 for the top of the lamp head 4 to be inserted. A tapered guide groove 16 is provided on the outer edge of the bottom surface of the crimping part 11. The tapered guide groove 16 tapers inward from bottom to top and is used to allow the latch 14 on the lamp head 4 to enter when the lamp head 4 is inserted into the positioning cavity 15 to position the lamp head 4.

[0036] 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.
