[0014] Dispensing assembly for dispensing adhesive onto the top surface of the lamp holder;

[0015] Bulb mounting assembly for placing bulbs on the top surface of the lamp reflector;

[0016] Between the lamp holder mounting assembly and the second lamp cup flipping assembly, a lamp holder riveting assembly is also provided, which is used to radially compress and deform the lamp holder to clamp and fix it to the lamp cup.

[0017] Furthermore, a cable management assembly is provided between the first lamp cup flipping assembly and the lamp head mounting assembly. The cable management assembly includes a first cable management gripper, a second cable management gripper, and a cable management lifting drive. The first cable management gripper can open and close laterally to clamp the wire. The second cable management gripper is above the first cable management gripper and can open and close laterally to clamp the wire above the first cable management gripper. The cable management lifting drive is connected to and used to drive the second cable management gripper to lift and straighten the wire upward.

[0018] Furthermore, a first lighting detection component is provided between the lamp holder mounting component and the wire cutting and bending component. The first lighting detection component is used to contact and connect the wire to the circuit, thereby lighting up the lamp board.

[0019] A second lighting detection component is provided between the electrode mounting assembly and the second lamp cup flipping assembly. The second lighting detection component is used to contact and connect the electrode to the circuit, thereby lighting up the lamp board.

[0023] The lamp head discharge mechanism is used to discharge the lamp head;

[0024] The lamp head pushing mechanism has a lamp head receiving plate that is supported at the outlet of the lamp head discharging mechanism. The lamp head pushing mechanism is also equipped with a pushing head, which is located above the lamp head receiving plate and is slidably arranged laterally. It is used to push the lamp head above the lamp head receiving plate into the lamp head limiting seat located next to the lamp head receiving plate.

[0025] The lamp holder includes a first half and a second half of the lamp holder that are horizontally openable and closable. When the first half and the second half of the lamp holder are closed, they receive and position the lamp holder pushed from the lamp holder receiving plate. When the first half and the second half of the lamp holder are open, the lamp holder can fall downwards to the top of the lamp cup on the positioning seat below it. When the first half and the second half of the lamp holder are closed, they also form a wire hole for the wire of the top of the lamp cup on the positioning seat below it to pass through.

[0026] The lamp holder assembly includes a conduit and a lamp holder pressure head. The conduit is height-adjustable so that after it is lowered, it can pass through the wire hole on the lamp holder and enter the lamp holder, and mate with the wire hole so that the wire passing through the wire hole can enter. The lamp holder pressure head is height-adjustable so that when the first half and the second half of the lamp holder limiting seat are open, it can press the lamp holder down to the top of the lamp cup.

[0027] Furthermore, the wire cutting and bending assembly includes a fixed blade, a movable blade, a movable blade drive mechanism, and a bending pressure head. The fixed blade is located above the positioning seat of the wire cutting and bending assembly and has a wire cutting hole for the wire to pass through upward.

The front end of the movable blade is provided with a cutting end so that it cooperates with the wire cutting hole to cut the wire when the cutting end passes through the wire cutting hole. The movable blade has a punch through hole at the rear of the cutting end. A wire pressing arm for pressing and fixing the wire protrudes radially inside the punch through hole. When the punch through hole coincides with the wire cutting hole, the bending pressure head moves downward through the punch through hole and the wire cutting hole to bend the wire.

[0028] Furthermore, the electrode mounting assembly includes an electrode discharge device and an electrode loading suction head. The electrode discharge device is used to discharge the electrode in a set posture, and the electrode loading suction head is used to pick up the electrode discharged by the electrode discharge device and place it at a predetermined position on the top of the lamp head.

[0030] Furthermore, the lamp head riveting assembly has multiple riveting heads, which can descend to the riveting position of the lamp head and then approach the lamp head along the lamp head axis to squeeze and deform the lamp head to clamp it to the top of the lamp cup. The multiple riveting heads can also rise to avoid obstructing the lamp cup conveyed on the positioning seat below and the lamp head above the lamp cup.

[0031] Furthermore, an LED bulb includes a lamp cup, a lamp board, a lamp holder, electrodes, and a bulb shell;

[0032] The front of the lamp cup has a lamp plate mounting cavity, and the cross-sectional shape of the lamp plate mounting cavity is able to allow the lamp plate to be interference-fitted and fixed.

[0033] The lamp board is equipped with LED beads and wires that are electrically connected to the LED beads for supplying power to them. After the lamp board is embedded into the lamp cup, the LED beads face the front of the lamp cup, the wires face the back of the lamp cup, and extend out of the lamp cup from the back of the lamp cup.

[0034] The lamp holder is used to fit onto the back end of the lamp cup, so that it can be tightened onto the back end of the lamp cup after radial compression deformation. A wire through hole is formed on the lamp holder, which allows the wire to pass through and protrude when the lamp holder is fitted onto the back end of the lamp cup.

[0035] The electrode can be snapped onto the end of the lamp holder away from the lamp cup, and after snapping, it is electrically connected to the wire for external power supply.

[0036] The bulb is used to attach to the front of the lamp cup to cover the lamp panel inside, and it is made of a light-transmitting material.

[0037] After adopting the above solution, the beneficial effects of this utility model are as follows: At the lamp cup and lamp plate feeding station, the operator can place the lamp cup face up on the positioning seat, and then place the lamp plate on top of the lamp cup. The positioning seat then carries the lamp cup to the lamp plate pressing assembly, which presses the lamp plate down and embeds it into the lamp cup, thus fixing the lamp plate and lamp cup. Then, the positioning seat carries the lamp cup to the first lamp cup flipping assembly, which flips the lamp cup upside down and places it back on the positioning seat to facilitate the subsequent installation of the lamp head and electrode. Then, the positioning seat carries the lamp cup to the lamp head mounting assembly, which places the lamp head on the lamp cup and allows the wires on the lamp plate to pass through the wire hole at the top of the lamp head and exit upwards. Finally, the positioning seat carries the lamp cup to the wire cutting and bending assembly. The assembly process involves several steps: a wire cutting and bending assembly cuts and bends the wire through the lamp holder, then a positioning seat carries the lamp cup to an electrode mounting assembly. The electrode mounting assembly inserts and fixes the electrode to the lamp holder. Next, the positioning seat carries the lamp cup to a second lamp cup flipping assembly, where the lamp cup is inverted and placed back on the positioning seat for bulb installation. The positioning seat then carries the lamp cup to a dispensing assembly for dispensing, and finally to a bulb mounting assembly where a bulb is placed on top of the lamp holder to adhere it. Between the lamp holder mounting assembly and the second lamp cup flipping assembly, a lamp holder riveting assembly is provided to radially deform the lamp holder and clamp it to the lamp holder, achieving riveting fixation between the lamp holder and the lamp holder, thus improving the automation level of the LED bulb assembly process.

[0052] An LED bulb assembly line, such as Figure 1-10 As shown, the LED bulb 1 is assembled using conventional techniques in the art, and is a standard structure of commercially available LED bulbs 1. Specifically, in this embodiment... Figure 11As shown (the figure is only a schematic diagram for the purpose of understanding the content of this application and does not represent the actual structure of the assembled LED bulb), the LED bulb 1 specifically includes a lamp cup 4, a lamp plate 6, a lamp holder 10, an electrode 15, and a bulb shell 19; the lamp cup 4 is usually a white injection molded part, with a lamp plate mounting cavity 58 formed on the front side. The cross-sectional shape of the lamp plate mounting cavity 58 allows the lamp plate 6 to be interference-fitted and fixed; LED beads are provided on the lamp plate 6, and wires 11 are provided for electrically connecting to the LED beads and supplying power to the LED beads. After the lamp plate 6 is embedded in the lamp cup 4, the LED beads face the front of the lamp cup 4, and the wires 11 face the back of the lamp cup 4 and extend out of the lamp cup 4 from the back of the lamp cup 4; the lamp holder 10 is used to fit onto the back end of the lamp cup 4, so as to tighten onto the back end of the lamp cup 4 after radial compression deformation. A wire through hole 12 is formed on the lamp holder 10. At the end of the back of the cup 4, the wire through hole 12 allows the wire 11 to pass through and protrude. When the LED bulb is in use, it is electrically connected to the lamp holder by rotating the knob of the lamp holder 10. The lamp holder is connected to the household circuit to provide power for the LED bulb to emit light. The electrode 15 can be snapped onto the end of the lamp holder 10 away from the lamp cup 4 and is electrically connected to the wire 11 after snapping. The snapping structure between the electrode 15 and the lamp holder 10 can be any existing design in the art, which is a common technical means in the art and will not be specifically described. The electrode 15 is a contact point used to conduct the circuit and is used for external power supply. The bulb shell 19 is used to adhere to the front of the lamp cup 4 to cover the lamp plate 6 inside, and is made of light-transmitting material. The main functions of the bulb shell 19 include allowing the light emitted by the LED beads on the lamp plate 6 to pass through the LED bulb, so as to filter the light, protect the lamp, and extend the service life.

[0053] Key points combined Figure 1 , Figure 2 and Figure 6As shown, the LED bulb assembly line includes a conveyor line 2 for conveying positioning seats 3. The positioning seats 3 are cylindrical and upright, allowing the lamp cups 4 to be embedded and positioned downwards. The conveyor line 2 also includes a flexible belt 60, which lies flat on the machine table. The flexible belt 60 is limited by multiple guide wheels to form a loop on the machine table. Multiple positioning seats 3 are sequentially fixed on the flexible belt 60. Among the guide wheels is a drive wheel connected to a drive mechanism. The rotation of the drive wheel drives the flexible belt 60 to convey the positioning seats 3 along the loop path. Along the conveying path of the positioning seats 3, there are sequentially arranged lamp cup / lamp plate loading stations 5. The assembly includes a lamp pressing plate assembly 59, a first lamp cup flipping assembly 8, a lamp head mounting assembly 9, a wire cutting and bending assembly 13, an electrode mounting assembly 14, a second lamp cup flipping assembly 16, an adhesive dispensing assembly 17, and a bulb mounting assembly 18. A lamp head riveting assembly 20 is also provided between the lamp head mounting assembly 9 and the second lamp cup flipping assembly 16. Preferably, a wire management assembly 21 is provided between the first lamp cup flipping assembly 8 and the lamp head mounting assembly 9. Preferably, a first lighting detection assembly 25 is provided between the lamp head mounting assembly 9 and the wire cutting and bending assembly 13. Preferably, a second lighting detection assembly 26 is provided between the electrode mounting assembly 14 and the second lamp cup flipping assembly 16.

[0054] Station 5 for lamp cup and lamp plate loading, focusing on... Figure 1 As shown, an operating space 7 is formed in which the lamp cup 4 is placed face up on the positioning seat 3 and the lamp plate 6 is placed above the lamp cup 4. Specifically, in this embodiment, during operation, the operator manually places the lamp cup 4 and the lamp plate 6 on the positioning seat 3 at the operating space 7. Of course, an automatic feeding mechanism can also be set to automatically place the lamp cup 4 and the lamp plate 6 on the positioning seat 3 at the operating space 7. It is not specifically limited.

[0055] Light-pressing panel assembly 59, focusing on integration Figure 3 As shown, the lamp plate 6 is pressed down and embedded into the lamp cup 4. Specifically, it includes a lamp plate pressing head 61. When the positioning seat 3 carries the lamp cup 4 and the lamp plate 6 and moves to the lamp plate pressing head 61, the lamp plate pressing head 61 moves down electrically or pneumatically, pressing down the lamp plate 6 and pressing the lamp plate 6 into the lamp plate mounting cavity 58 of the lamp cup 4, so that the lamp plate 6 is interference-fitted and fixed into the lamp cup 4.

[0056] The first lamp cup flipping component 8, with key integration Figure 4 As shown, it is used to flip the lamp cup 4 upside down and put it back on the positioning seat 3, so that the lamp cup 4 turns to face up. The more specific structure of the first lamp cup flipping component 8 is given later.

[0057] Key points combined Figure 5As shown, the cable management assembly 21 includes a first cable management gripper 22, a second cable management gripper 23, and a cable management lifting drive 24. The first cable management gripper 22 is electrically or pneumatically driven to open and close laterally. When closed, it is used to clamp the wire 11, and when opened, it releases the wire 11 and makes way for the wire 11 during the transmission process. The second cable management gripper 23 is above the first cable management gripper 22 and is electrically or pneumatically driven to open and close laterally. When closed, it is used to clamp the wire 11 above the first cable management gripper 22. The cable management lifting drive 24 is connected to and used to drive the second cable management gripper 23 to lift and lower, so as to straighten the wire 11 when it clamps the guide 11 and moves upward. When the second cable management gripper 23 opens, it releases the wire 11 and makes way for the wire 11 during the transmission process.

[0058] Lamp holder mounting component 9, focusing on combination Figure 7As shown, the lamp holder 10 is placed on the lamp cup 4, and the wire 11 on the lamp plate 6 passes upward through the lamp holder 10. The top of the lamp holder 10 has a wire through hole 12, and the wire 11 passes upward through the wire through hole 12 and exits the lamp holder 10. Those skilled in the art can design and implement the above functions by combining conventional technical means in the art. In a more specific and preferred embodiment, the lamp holder mounting assembly 9 includes a lamp holder discharging mechanism 35, a lamp holder pushing mechanism 36, a lamp holder limiting seat 37, and a lamp holder pressing assembly 38. The lamp holder discharging mechanism 35 is a vibratory feeder, used to discharge the lamp holder 10 with its back facing upward. The lamp holder pushing mechanism 36 has a lamp holder receiving port that receives the lamp holder at the discharging port of the lamp holder discharging mechanism 35. The lamp head 10, discharged from the lamp head discharge mechanism 35, enters the lamp head receiving plate 39 in its original position (back side up). The lamp head pushing mechanism 36 is also provided with a pushing head 40, which is located above the lamp head receiving plate 39 and is laterally slidable. It is used to push the lamp head 10 above the lamp head receiving plate 39 into the lamp head limiting seat 37 located next to the lamp head receiving plate 39. The lamp head limiting seat 37 includes a first half 41 and a second half 42 of the lamp head limiting seat that are laterally openable and closeable. The first half 41 and the second half 42 of the lamp head limiting seat are closed to receive and position (forming a positioning groove that matches the shape and contour of the front side of the lamp head 10, i.e., the side that is installed in the lamp cup) from the lamp head receiving plate. The lamp holder 10 is pushed in, and the first half 41 and the second half 42 of the lamp holder limiting seat open to allow the lamp holder 10 to fall downwards onto the top of the lamp cup 4 on the positioning seat 3 below it. When the first half 41 and the second half 42 of the lamp holder limiting seat are closed, they form a wire hole 43 for the wire 11 at the top of the lamp cup 4 on the positioning seat 3 below it to pass through. The lamp holder pressing assembly 38 includes a wire tube 44 and a lamp holder pressing head 45. The wire tube 44 is raised and lowered so that after falling, it can pass through the wire hole 12 on the lamp holder 10 into the lamp holder 10 and mate with the top of the wire hole 43 so that the wire 11 that passes upwards out of the wire hole 43 can enter. The lamp holder limiting seat 37, the wire tube 44 and the lamp holder pressing head 45 are connected. The lamp holder pressure head 45 can rise and fall together. During operation, the conduit 44 and the lamp holder pressure head 45 descend first, and the lamp holder pressure head 45 presses on the lamp holder 10. The conduit 44 passes down through the wire hole 12 on the lamp holder 10 and extends into the lamp holder 10, connecting with the wire hole 43. Then, the lamp holder limiting seat 37, the conduit 44 and the lamp holder pressure head 45 descend together, so that the wire 11 at the top of the lamp cup 4 located below the lamp holder limiting seat 37 passes through the wire hole 43 and enters the conduit 44. Then, the first half 41 and the second half 42 of the lamp holder limiting seat open, and the lamp holder pressure head 45 presses down on the lamp holder 10 to the top of the lamp cup 4, thereby realizing the installation of the lamp holder 10 and the lamp cup 4, and realizing the wire threading of the guide 11 on the lamp holder 10.In a more specific embodiment, when the conduit 44 descends, the lamp holder pressure head 45 descends along with it. An elastic element is provided between the two. After the lamp holder pressure head 45 presses down to the top of the lamp holder 10, the conduit 44 continues to descend. At this time, the elastic element is compressed. Then, when the first half 41 and the second half 42 of the lamp holder limiting seat open, the elastic force of the elastic element causes the lamp holder pressure head 45 to spring downwards, causing the lamp holder 10 to press down to the top of the lamp cup 4.

[0059] The first lighting detection component 25 is used to contact and connect the circuit to the wire 11 to light up the lamp board 6 and detect defective products with abnormal lighting.

[0060] Cutting and folding component 13, focusing on combination Figure 8 As shown, the wire 11 used for cutting and bending downwards through the lamp holder 10 can adopt existing conventional designs with corresponding functions in the art, and is not specifically limited; in a preferred embodiment, the wire cutting and bending assembly 13 includes a fixed blade 46, a movable blade 47, a movable blade driving mechanism 48, and a bending pressure head 49. The fixed blade 46 is located above the positioning seat 3 at the wire cutting and bending assembly 13, and is provided with a wire cutting hole 50 for the wire 11 to pass upwards. The movable blade 47 is attached to the fixed blade 46 and slides against the top surface of the fixed blade 46 under the drive of the movable blade driving mechanism 48. The blade 47 has a cutting end at its front end, which is used to cut the wire 11 when the cutting end passes through the wire cutting hole 50. The moving blade 47 has a punch through hole 51 at the rear of the cutting end. A pressure arm 52 for pressing and fixing the wire 11 protrudes radially inside the punch through hole 51. The pressure arm 52 bends the wire by 90 degrees. When the punch through hole 51 coincides with the wire cutting hole 50, the bending pressure head 49 moves downward through the punch through hole 51 and the wire cutting hole 50 to bend the wire 11, so that the end of the wire 11 is further bent downward.

[0061] Electrode mounting assembly 14, focusing on integration Figure 9 As shown, the electrode 15 is inserted and fixed onto the lamp holder 10. Existing conventional designs with corresponding functions in the art can be used, and are not specifically limited. In a preferred embodiment, the electrode mounting assembly 14 includes an electrode discharging device 54 and an electrode feeding suction head 55. The electrode discharging device 54 is used to discharge the electrode 15 according to a set posture, and the electrode feeding suction head 55 is used to suck up the electrode 15 discharged by the electrode discharging device 54 and place it at a predetermined position at the top of the lamp holder 10. The electrode mounting assembly 14 also includes an electrode pressing head 56, used to press down on the electrode 15 to snap and fix the electrode 15 onto the lamp holder 10, thereby completing the installation of the electrode 15 on the lamp holder 10.

[0062] The second lighting detection component 26 is used to contact and connect the circuit to the electrode 15 to light up the lamp board 6 and detect defective products with abnormal lighting.

[0063] Key points combined Figure 10 As shown, in this embodiment, the lamp head riveting assembly 20 is specifically located at the next station after the second lighting detection assembly 26. It is used to radially compress and deform the lamp head 10 to clamp and fix it to the lamp cup 4. The lamp head riveting assembly 20 has multiple riveting heads 57. The multiple riveting heads 57 can descend to the riveting position of the lamp head 10 and then approach the lamp head 10 along the axial direction of the lamp head 10 to compress and deform the lamp head 10 to clamp it to the top of the lamp cup 4. The multiple riveting heads 57 can also rise to avoid the lamp cup 4 conveyed on the positioning seat 3 below and the lamp head 10 above the lamp cup 4. This is a conventional design in the field and will not be described in more detail, thereby achieving the fixation of the lamp head 10 and the lamp cup 4.

[0064] The second lamp cup flipping assembly 16 is used to flip the lamp cup 4 upside down and place it back onto the positioning base 3; the first lamp cup flipping assembly 8 and the second lamp cup flipping assembly 16 have the same structure, with the key features being their combination. Figure 4 and Figure 6 As shown, the system includes a column 27, a first sliding seat 28, a second sliding seat 29, a lamp holder tilting first lifting cylinder 30, a lamp holder tilting second lifting cylinder 31, a lamp holder rotating cylinder 32, a lamp holder tilting gripper opening and closing drive 33, and a lamp holder tilting gripper 34. The first sliding seat 28 is longitudinally slidably mounted on the column 27, and the second sliding seat 29 is located below the first sliding seat 28 and longitudinally slidably mounted on the column 27. The lamp holder tilting first lifting cylinder 30 is connected between the column 27 and the first sliding seat 28, and is used to drive the first sliding seat 28 to slide longitudinally and the lamp holder tilting second lifting cylinder 31 to rotate. The lowering cylinder 31 is connected between the first sliding seat 28 and the second sliding seat 29, and is used to drive the second sliding seat 29 to slide longitudinally so as to move up and down relative to the first sliding seat 28.
