Technical Field

[0001] This utility model relates to the technical field of automatic LED bulb assembly equipment, and in particular to a multi-station LED bulb assembly line. Background Technology

[0002] Currently, there are automated machines on the market for assembling LED bulbs. However, each station of such machines can only assemble one bulb at a time, resulting in limited production efficiency. The only way to increase production capacity is to increase the number of machines, but this will lead to a significant increase in equipment purchase costs and space requirements.

[0003] The question of how to use automated equipment to assemble LED bulbs to increase production capacity while minimizing equipment costs and space usage remains to be addressed. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-station LED bulb assembly line, and the technical problem to be solved is how to increase the production efficiency of LED bulb assembly equipment by a factor of two while saving costs as much as possible.

[0005] To achieve the above objectives, the solution of this utility model is: a multi-station LED bulb assembly line for assembling LED bulbs, including a first workbench, a second workbench, and a transfer robot;

[0006] The top surface of the first workbench is provided with a first conveying device. The first conveying device is used to cyclically convey multiple first positioning seats. The top surface of the first positioning seat is used for embedding and placing lamp cups. Multiple feeding stations are formed around the first workbench. The feeding stations are used for people to place lamp cups into the first positioning seats and place lamp boards on the lamp cups.

[0007] The top surface of the second workbench is equipped with a second conveying device, which is used to cyclically convey multiple second positioning seats. The top surface of the second positioning seats is used for embedding and placing lamp cups. The transfer robot is used to pick up and place the lamp cups on the first positioning seats into the second positioning seats downstream of the loading station. The top surface of the second workbench is equipped with multiple lamp head mounting components, multiple wire cutting and bending components, multiple nailing components, multiple second lamp cup flipping components, multiple glue dispensing components, and multiple blister packing components in sequence along the conveying path of the second positioning seats downstream of the transfer robot. A corresponding number of lamp head riveting components are also provided between the lamp head mounting components and the second lamp cup flipping components.

[0008] Furthermore, the first workbench is also equipped with a lamp plate pressing assembly, which is located above the first positioning seat conveying path on the first workbench and downstream of the loading station and upstream of the transfer robot. The lamp plate pressing head is provided to press the lamp plate down and embed it into the lamp cup.

[0009] Furthermore, the first workbench is also provided with a first lamp cup flipping assembly, which is located downstream of the lamp pressing plate assembly and upstream of the transplanting robot, and is used to flip the lamp cup in the first positioning seat up and down and put it back into the first positioning seat.

[0010] Furthermore, the first workbench is also equipped with a hanging edge line station, which is located downstream of the first lamp cup flipping assembly and upstream of the transplanting robot, so that a person can hook the edge line on the lamp plate inside the first positioning seat onto the lamp cup.

[0011] Furthermore, the second workbench is also equipped with multiple cable management components. The cable management components are located upstream of the lamp holder components. The cable management components include a first cable management gripper and a second cable management gripper. The first cable management gripper can open and close laterally to clamp the center line. The second cable management gripper is above the first cable management gripper and can open and close laterally to clamp the center line above the first cable management gripper. The second gripper can rise and fall to straighten the center line upwards.

[0012] Furthermore, along the conveying path of the second positioning seat, the top surface of the second workbench is sequentially equipped with two lamp holder assembly, two wire cutting and bending assembly, two nailing assembly, two second lamp cup flipping assembly, two glue dispensing assembly, and two blister packing assembly.

[0013] Furthermore, the lamp holder assembly is used to place the lamp holder onto the lamp cup and to allow the center line on the lamp plate to pass through the lamp holder upwards. The top of the lamp holder has a center line through-hole, and the center line passes through the center line through-hole and exits the lamp holder upwards.

[0014] The wire cutting and bending assembly is used to cut and bend downwards through the center line of the lamp holder;

[0015] A mounting assembly for attaching and securing the electrodes to the lamp holder;

[0016] The second lamp cup flipping assembly is used to flip the lamp cup in the second positioning seat up and down and then put it back into the second positioning seat;

[0017] Dispensing assembly for dispensing adhesive onto the top surface of the lamp holder;

[0018] Bulb assembly, used to place the bulb on the top surface of the lamp cup;

[0019] The lamp holder riveting assembly is used to radially compress and deform the lamp holder to secure it to the lamp cup.

[0020] Furthermore, an LED bulb includes a lamp cup, a lamp board, a lamp holder, electrodes, and a bulb shell;

[0021] 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.

[0022] The light panel is equipped with LED beads and has a center line and side line that are electrically connected to the LED beads and used to supply power to the LED beads. After the light panel is embedded into the lamp cup, the LED beads face the front of the lamp cup, the center line and side line face the back of the lamp cup and extend out of the lamp cup. The side line is used to hook onto the lamp cup.

[0023] The lamp holder is used to fit onto the back end of the lamp cup. After fitting, it is electrically connected to the edge wire and is tightened onto the back end of the lamp cup after radial compression deformation. A center line through hole is formed on the lamp holder. When the lamp holder is fitted onto the back end of the lamp cup, the center line through hole allows the center line to pass through and protrude.

[0024] The electrode can be snapped onto the end of the lamp holder away from the lamp cup and connected to the neutral wire after snapping.

[0025] 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.

[0026] The beneficial effects of this utility model after adopting the above solution are as follows: The first conveying device is used to cyclically convey multiple first positioning seats. Multiple loading stations are formed around the periphery of the first workbench. The loading stations are for personnel to place lamp cups into the first positioning seats and place lamp boards on the lamp cups. A second conveying device is provided on the top surface of the second workbench. The second conveying device conveys the second positioning seats. The transfer robot is used to pick up and place the lamp cups on the first positioning seats into the second positioning seats downstream of the loading stations. Along the conveying path of the second positioning seats downstream of the transfer robot, the top surface of the second workbench is sequentially provided with multiple lamp head mounting components, multiple wire cutting and bending components, multiple nailing components, multiple second lamp cup flipping components, multiple glue dispensing components, and multiple bubble filling components. The housing assembly also includes multiple lamp head riveting assemblies located between the lamp head assembly and the lamp cup flipping assembly. Thus, manual operations such as loading the lamp cup and lamp board are completed on the first workbench, independent of the second workbench. This avoids occupying space on the second workbench for the various automated components and allows for flexible scheduling of operators based on production capacity needs, while also enhancing operator safety. The second workbench features multiple lamp head assembly, wire cutting and bending assembly, nailing assembly, second lamp cup flipping assembly, glue dispensing assembly, bulb housing assembly, and lamp head riveting assembly, enabling the simultaneous assembly of multiple LED bulbs. This achieves a significant increase in production efficiency at minimal cost. Attached Figure Description

[0039] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] 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.

[0041] A multi-station LED bulb assembly line is used to assemble LED bulbs 1. The LED bulb 1 includes a lamp holder 7, a lamp board 9, a lamp base 28, an electrode 30, and a bulb shell 31, with a focus on combining... Figure 11 As shown; the lamp cup 7 has a lamp plate mounting cavity 32 formed on its front side, and the cross-sectional shape of the lamp plate mounting cavity 32 is suitable for the lamp plate 9 to be interference-fitted and fixed; LED beads are provided on the lamp plate 9, and a center line 27 and a side line 23 are provided for electrically connecting to the LED beads and supplying power to the LED beads. After the lamp plate 9 is embedded into the lamp cup 7, the LED beads face the front of the lamp cup 7, and the center line 27 and the side line 23 face the back of the lamp cup 7 and extend out of the lamp cup 7 from the back of the lamp cup 7. The side line 23 is used to hook onto the lamp cup 7; the lamp head 28 is used to fit onto the back end of the lamp cup 7. After fitting, it contacts the side line 23 to form an electrical connection. The lamp head 28 is tightened after radial compression deformation. At the rear end of the lamp cup 7, a center line through hole 29 is formed on the lamp holder 28. When the lamp holder 28 is fitted onto the rear end of the lamp cup 7, the center line through hole 29 allows the center line 27 to pass through and extend. The electrode 30 can be snapped onto the end of the lamp holder 28 away from the lamp cup 7 and is electrically connected to the center line 27 after snapping. The bulb shell 31 is used to adhere to the front of the lamp cup 7 to cover the lamp plate 9 inside. The bulb shell 31 is made of a light-transmitting material to transmit light when the LED beads emit light. The above is an E27 specification LED bulb. Of course, the layout and design of a multi-station LED bulb assembly line of the present invention are also applicable to assembly equipment for other specifications of LED bulbs such as B22.

[0042] Key points combined Figure 1-10As shown, the multi-station LED bulb assembly line includes a first workbench 2, a second workbench 3, and a transfer robot 4. A first conveying device 5 is provided on the top surface of the first workbench 2. The first conveying device 5 is used to cyclically convey multiple first positioning seats 6. Specifically, the first conveying device 5 includes a flexible belt 34 extending around the workbench 2. The flexible belt 34 is laid flat on the workbench 2 surface and is limited by multiple guide wheels to form a loop around the workbench 2 surface. Multiple first positioning seats 6 are sequentially fixed on the flexible belt 34. Among the multiple guide wheels is a drive wheel connected to a drive mechanism. The rotation of the drive wheel drives the flexible belt 34 to convey the first positioning seats 6 along the loop path. The first positioning seats 6 are cylindrical and upright, so that the top surface of the first positioning seats 6 is used for embedding and placing lamp cups 7. Multiple loading stations 8 are formed around the periphery of the first workbench 2. The loading stations 8 are used for personnel to place lamp cups 7 into the first positioning seats 6 and place lamp plates 9 on the lamp cups 7. When placing the lamp cup 7, the front of the lamp cup 7 should face upwards. Preferably, to reduce manpower, the first workbench 2 is also equipped with a lamp plate pressing assembly 20, a first lamp cup flipping assembly 19, and an edge hanging station 22. The lamp plate pressing assembly 20 is located above the conveying path of the first positioning seat 6 on the first workbench 2 and downstream of the loading station 8. It is equipped with a lamp plate pressing head (not shown in the attached figure, but capable of pressing down the lamp plate). The lamp plate pressing head is used to press down and embed the lamp plate 9 into the lamp cup 7. The first lamp cup flipping assembly 19 is downstream of the lamp plate pressing assembly 20 and is used to flip the lamp cup 7 in the first positioning seat 6 and put it back into the first positioning seat 6. The edge hanging station 22 is downstream of the first lamp cup flipping assembly 19 and is used for people to hook the edge line 23 on the lamp plate 9 in the first positioning seat 6 onto the lamp cup 7. The loading station 8 and the edge hanging station 22 require manual operation by operators. According to the production capacity, a corresponding number of operators can be arranged at the loading station 8 and the edge hanging station 22 to perform the operation.

[0043] The top surface of the second workbench 3 is provided with a second conveying device 10. The second conveying device 10 is used to cyclically convey multiple second positioning seats 11. The second conveying device 10 has the same structural principle as the first conveying device 5, so it will not be described in detail. The top surface of the second positioning seat 11 is used for embedding and placing the lamp cup 7. The transfer robot 4 is used to pick up and place the lamp cup 7 from the first positioning seat 6 into the second positioning seat 11 downstream of the loading station 8. Specifically, in this embodiment, the transfer robot 4 is set on the second workbench 3. The first workbench 3 is located next to the transfer robot 4, allowing the transfer robot 4 to pick up and place the lamp cup 7 from the first positioning seat 6 downstream of the edge hanging station 22. The base 6 grips the lamp cup 7. On the top surface of the second worktable 3, downstream of the transfer robot 4 and along the conveying path of the second positioning base 11, are sequentially arranged multiple lamp head assembly 12, multiple wire cutting and bending assemblies 13, multiple nailing assemblies 14, multiple second lamp cup flipping assemblies 15, multiple glue dispensing assemblies 16, and multiple bulb assembly assemblies 17. A corresponding number of lamp head riveting assemblies 18 are also arranged between the lamp head assembly 12 and the second lamp cup flipping assemblies 15 to complete the lamp head assembly, center line cutting, electrode installation, glue dispensing, bulb assembly, and lamp head riveting on the lamp cup 7, thereby completing the assembly of the entire LED bulb. In a preferred embodiment, the second worktable 3 is also provided with multiple wire management assemblies 24, located upstream of the lamp head assembly 12, to prevent the center line 27 from excessively bending during lamp head assembly, thus preventing it from passing through the center line perforation 29.

[0044] Specifically, in this embodiment, the top surface of the second workbench 3 is sequentially provided with two wire organizing components 24, two lamp holder mounting components 12, two wire cutting and bending components 13, two nailing components 14, two lamp holder riveting components 18, two second lamp cup flipping components 15, two glue dispensing components 16, and two blister packing components 17. Of course, the number is not limited to two. It can be understood that the more components the second workbench 3 is provided with, the more the number of loading stations 8, lamp pressing plate components 20, first lamp cup flipping components 19, and edge hanging stations 22 on the first workbench 2 should also be increased accordingly. Of course, the working speed of the operator at the loading station 8 and the edge hanging station 22 should also be considered. Those skilled in the art can match and set them according to actual needs. This doubles production capacity while saving costs and space compared to purchasing multiple single-station bulb assembly equipment for simultaneous production. Furthermore, the operators are positioned further away from the automated components on the second workbench 3 (such as the wire feeding assembly 24, the lamp holder assembly 12, the wire cutting and bending assembly 13, the nailing assembly 14, the lamp holder riveting assembly 18, the second lamp cup flipping assembly 15, the glue dispensing assembly 16, and the bulb shell assembly 17), making the process safer.

[0045] Specifically in this embodiment:

[0046] Key points combined Figure 4As shown, the cable management assembly 24 includes a first cable management gripper 25 and a second cable management gripper 26. The first cable management gripper 25 can open and close laterally to grip the center line 27. The second cable management gripper 26 is above the first cable management gripper 25 and can also open and close laterally to grip the center line 27 above the first cable management gripper 25. The second cable management gripper 26 can rise and fall to straighten the center line 27 upwards. When the second cable management gripper 26 opens, it releases the center line 27 and makes way for the center line 27 during the transmission process. More preferably, in this embodiment, in order to save costs, the first cable management grippers 25 of the two cable management assemblies 24 share a set of drive mechanisms for opening and closing, and the second cable management grippers 26 of the two cable management assemblies 24 also share a set of drive mechanisms for opening, closing and rising and falling. The drive mechanism mentioned in this paragraph is preferably pneumatic, so that the center lines on the lamp panels 9 in the two adjacent second positioning seats 11 below can be straightened upwards at a lower cost.

[0047] Key points combined Figure 5 and Figure 11As shown, the lamp holder assembly 12 is used to place the lamp holder 28 onto the lamp cup 7, and to allow the center line 27 on the lamp plate 9 to pass upward through the lamp holder 28. Specifically, the top of the lamp holder 28 has a center line through hole 29, and the center line 27 passes upward through the center line through hole 29. 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 assembly 12 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 28 with its back facing upward. The lamp holder pushing mechanism 36 has a lamp holder receiving plate that receives the lamp holder at the discharge port of the lamp holder discharging mechanism 35. 39. The lamp head 28 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 28 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 opened and closed. 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 28 that is installed in the lamp cup) the lamp head 28 pushed from the lamp head receiving plate 39.The lamp holder assembly 38 includes a conduit 44 and a lamp holder pressure head 45. The conduit 44, lamp holder pressure head 45, and lamp holder limiting seat 37 are all mounted on a sliding main frame 57. During operation, the conduit 44 descends on the sliding main frame 57, simultaneously lowering the lamp holder pressure head 45. The lamp holder pressure head 45 descends and presses against the lamp holder 28, after which it can no longer descend. An elastic element 58 is provided between the mounting structure of the lamp holder pressure head 45 and the mounting structure of the lamp holder conduit 44. When the conduit 44 continues to descend, it compresses the elastic element to store energy. The conduit 44 continues to descend until it passes through the centerline through-hole 29 on the lamp holder 28 and enters the lamp holder 28. After the first half 41 and the second half 42 of the lamp holder limiting seat are closed, a conduit hole 43 is formed. The conduit 44 continues... The main frame 57 descends and connects to the top of the threading hole 43. Then, the sliding main frame 57 descends, driving the threading tube 44, the lamp holder pressure head 45, and the lamp holder limiting seat 37 to descend simultaneously. After descending, the center line 27 of the lamp cup 7 extending upward below the lamp holder limiting seat 37 will first pass through the threading hole 43 and then enter the threading tube 44. The first half 41 and the second half 42 of the lamp holder limiting seat can open and be withdrawn below the lamp holder. After withdrawal, under the rebound action of the elastic member 58, the lamp holder pressure head 45 will spring down and press the lamp holder 28 down to the top of the lamp cup 7, thereby realizing the installation of the lamp holder 28 and the lamp cup 7, and realizing the threading of the center line 27 on the lamp holder 28. In this embodiment, the lamp holder mounting assembly 12 is specifically provided in two parts, so that the lamp holder 28 can be installed on the lamp cup 7 in the two adjacent second positioning seats 11 below at the same time.

[0048] Key points combined Figure 6As shown, the wire cutting and bending assembly 13 is used to cut and bend downwards the center line 27 that passes through the lamp holder 28; it 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 second positioning seat 11 at the wire cutting and bending assembly 13, and is provided with a wire cutting hole 50 for the center line 27 to pass through upwards. The movable blade 47 is attached to the fixed blade 46 and slides on the top surface of the fixed blade 46 under the drive of the movable blade driving mechanism 48. The front end of the movable blade 47 is provided with a cutting end. When the cutting end passes through the cutting hole 50, it cooperates with the cutting hole 50 to cut the center line 27. The moving blade 47 is provided with a punch through hole 51 at the rear of the cutting end. The punch through hole 51 has a radially protruding pressing arm 52 for pressing and fixing the center line 27. The pressing arm 52 bends the wire by 90 degrees. When the punch through hole 51 coincides with the cutting hole 50, the bending pressing head 49 moves downward through the punch through hole 51 and the cutting hole 50 to bend the center line 27, so that the end of the center line 27 bends further downward, thereby being able to cut the center line 27 exposed in the lamp head 28 in the two adjacent second positioning seats 11 below at the same time.

[0049] Key points combined Figure 7 As shown, the mounting assembly 14 is used to insert and fix the electrode 30 to the lamp holder 28. It can adopt existing conventional designs with corresponding functions in the art and is not specifically limited. In a preferred embodiment, the mounting assembly 14 includes an electrode discharging device 53 and an electrode feeding suction head 54. The electrode discharging device 53 is used to discharge the electrode 30 in a set posture, and the electrode feeding suction head 54 is used to suck the electrode 30 discharged by the electrode discharging device 53 to a predetermined position at the top of the lamp holder 28. The mounting assembly 14 also includes an electrode pressing head (which can press the electrode 30 down from above, a conventional technical means, not shown in the figure) for pressing down the electrode 30 so that the electrode 30 is snapped and fixed to the lamp holder 28, thereby enabling the electrode 30 to be installed on the lamp holder 28 in the two adjacent second positioning seats 11 below at the same time.

[0050] Key points combined Figure 9 As shown, the lamp head riveting assembly 18 is used to radially compress and deform the lamp head 28 to clamp and fix it to the lamp cup 7. The riveting assembly 18 has multiple riveting heads 56. The multiple riveting heads 56 can descend to the riveting position of the lamp head 28 and then approach the lamp head 28 along the axial direction of the lamp head 28 to compress and deform the lamp head 28 to clamp it to the top of the lamp cup 7. The multiple riveting heads 56 can also rise to avoid the lamp cup 7 conveyed on the second positioning seat 11 below and the lamp head 28 above the lamp cup 7. This is a conventional design in the art and will not be described in more detail. In this way, the lamp head 28 and the lamp cup 7 in the two adjacent second positioning seats 11 below are fixed.

[0051] The second lamp cup flipping assembly 15 is used to flip the lamp cup 7 inside the second positioning seat 11 up and down and then put it back into the second positioning seat 11. It can be any kind of robot in the art that can achieve this function, preferably a pneumatic robot.

[0052] The dispensing assembly 16 is used to dispense adhesive onto the top surface of the lamp cup 7. Specifically, it performs circumferential dispensing on the outer ring of the top surface of the lamp cup. This is a conventional design in the art and will not be described in detail.

[0053] The bulb assembly 17 is used to place the bulb 31 on the top surface of the lamp cup 7. This can be achieved by using an existing robotic arm to place the bulb 31 onto the lamp cup 7.

[0054] 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.
