Implementation Method

[0026] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following examples. It should be understood that the following text is only used to describe one or more specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0027] As used herein, the terms "parallel," "perpendicular," and the like are not limited to their strict geometric definitions, but include allowances for reasonable and inconsistent machining or human errors.

[0028] like Figure 1 、 2 As shown, an LED lamp assembly conveying device includes a conveying line for conveying a light-transmitting cover body 60. The light-transmitting cover body 60 is annular, and the cross section of the light-transmitting cover body 60 is an inverted U-shaped. A connecting claw 61 is provided on the inner wall surface of the light-transmitting cover body 60. The lower end of the connecting claw 61 extends to the lower side of the lower side of the light-transmitting cover body 60 (that is, the clamping end of the connecting claw 61 extends to the outside or exterior of the light-transmitting cover body 60). The connecting claws 61 are arranged at intervals along the circumference of the light-transmitting cover body 60. A claw adjustment mechanism is provided on the conveying path of the conveying line to adjust the connecting claws 61 on the light-transmitting cover body 60 to a desired state. The structure of the light-transmitting cover body 60 is specifically as follows Figure 9 As shown, the light-transmitting cover 60 is placed upside down.

[0029] Specifically, the claw adjustment mechanism includes a clamping unit 20 that clamps or compresses the light-transmitting cover 60, a rotation unit that rotates the light-transmitting cover 60, and a lifting and lowering adjustment unit. The lifting and lowering adjustment unit adjusts the clamping unit 20 and the rotation unit. The conveyor line is equipped with a clamping body 31 that supports each light-transmitting cover. The claw adjustment mechanism adjusts the state of the connecting claws 61 of the light-transmitting cover 60 supported by the clamping body 31. The conveyor line consists of an endless conveyor belt or a turntable 05. The specific operation can be selected based on the subsequent automated assembly process.

[0030] A more specific solution is as follows: the rotating unit includes a rotating adjustment shaft 10 that is vertically rotatably mounted, and the rotating adjustment shaft 10 is provided with an upper connecting member 14 for transmission connection with the lower connecting member 34 provided on the clamping body 31. The lifting and lowering adjustment unit adjusts the rotating adjustment shaft 10 to lift and lower, and the clamping unit 20 is provided on the rotating adjustment shaft 10. A loading station and an unloading station are provided on the conveyor line, and an adjustment station is provided between the loading station and the unloading station, and the claw adjustment mechanism is provided at the adjustment station. The rotating adjustment shaft 10 includes an upper shaft body 11 and a lower shaft body 12 arranged upper and lower, and the lower shaft body 12 is installed on the upper shaft body 11 through an elastic driving member 13, and the clamping unit 20 and the upper connecting member 14 are provided on the lower shaft body 12, and the elastic driving member 13 adjusts the lower shaft body 12 to move downward. The lifting and adjusting unit lowers the rotating adjustment shaft 10 to compress the light-transmitting cover 60. When the connecting claw 61 on the light-transmitting cover 60 falls into the recess 32 on the supporting surface, the elastic driving member 13 drives the lower shaft 12 downward, thereby achieving a transmission connection between the upper connecting member 14 and the lower connecting member 34, thereby driving the lower connecting member 34 to move, thereby adjusting the posture of the light-transmitting cover 60 to a predetermined state. The adjustment support device rotates 90 degrees synchronously with the rotating adjustment shaft 10, primarily to address the problem of the connecting claw 61 (made of plastic) being easily damaged by rotational inertia.

[0031] In a more detailed solution, the elastic driving member 13 is composed of a driving spring, and the upper connecting member 14 is composed of an upper end face gear provided at the lower end of the lower shaft body 12. The clamping unit 20 includes a pressure plate 21 fixed to the lower shaft body 12, and an annular groove 22 arranged concentrically with the lower shaft body 12 is provided on the lower plate surface of the pressure plate 21. An annular guide ring 23 extending downward is provided at the notch of the inner groove wall of the annular groove 22, and the outer wall radius of the annular guide ring 23 gradually decreases from top to bottom. Figure 4 As shown, the provision of the annular guide ring 23 can guide the light-transmitting cover 60 during the downward movement, so that the light-transmitting cover 60 and the rotation adjustment shaft 10 are arranged concentrically. Specifically, a support frame 02 can be provided next to the turntable 05. A cantilevered mounting arm 06 can be provided at the upper end of the support frame 02. The assembly end of the mounting arm 06 can slide and be assembled on the support frame 02 in a vertical direction. The rotation adjustment shaft 10 can be mounted on the other end of the mounting arm 06 in a cantilevered manner. The rotation adjustment shaft 10 is connected to the rotation drive motor 03 provided on the mounting arm 06. The lifting and adjusting unit includes a lifting and adjusting cylinder 04 located next to the turntable 05. The piston rod of the lifting and adjusting cylinder 04 is connected to the mounting arm 06. The support frame 02 and the turntable 05 are both assembled on the frame 01.

[0032] like Figure 3 、 4As shown, the supporting device includes a clamping body 31, which is rotatably mounted on the turntable 05. The clamping body 31 is arranged at intervals along the circumference of the turntable 05. The clamping body 31 is provided with a supporting surface for supporting the light-transmitting cover 60. The supporting surface is provided with recessed portions 32 for accommodating the connecting claws 61. The recessed portions 32 are arranged at intervals along the circumference of the centerline of the clamping body 31. The clamping body 31 has a lower connecting member 34, which is used for detachable transmission assembly connection with the claw body adjustment mechanism. A circular void is provided in the middle of the clamping body 31, and the recessed portions 32 are arranged in the circular void. The circular void is used to expose the lower connecting member 34, allowing it to be transmission-connected to the upper connecting member 14.

[0033] A more preferred solution is that the lower connecting member 34 is movably mounted on the clamping body 31, and the position of the lower movable connecting member is adjusted to achieve separation from the claw body adjustment mechanism. The lower connecting member 34 is assembled and movably in the vertical direction. The lower connecting member 34 is movably mounted on the clamping body 31 in the vertical direction by an adjustment spring 35. The adjustment spring 35 drives the lower connecting member 34 downward. When the lower connecting member 34 is in the high position, it is used to assemble and connect with the claw body adjustment mechanism. The lower connecting member 34 moves downward from the high position to achieve separation from the claw body adjustment mechanism. It also includes an adjustment constraint 40, which is used to ensure that the lower connecting member 34 remains in the high position during rotation. The height of the support surface is less than the height of the turntable 05. The lower connecting part 34 is installed in the middle of the upper surface of the assembly part 33. The circular assembly part 33 is movably installed on the clamping body 31 through four guide rods. The adjustment spring 35 is set on the guide rod. The middle of the lower surface of the assembly part 33 is provided with an assembly foot 37. Three assembly feet 37 are provided. Specifically, a circular tube section can be provided in the middle of the lower surface of the assembly part 33, and the assembly foot 37 is provided on the lower end surface of the circular tube section.

[0034] The adjustment constraint 40 is set at the adjustment station. The adjustment constraint 40 is installed on the constraint lifting adjustment mechanism. The constraint lifting adjustment mechanism adjusts the adjustment constraint 40 to lift and lower. The clamping body 31 is also provided with an auxiliary adjustment member 36. The auxiliary adjustment member 36 is used to adjust the clamping body 31 to restore the initial state. The lower connecting member 34 is provided with a protruding assembly foot 37. The adjustment constraint 40 is composed of a vertically arranged circular adjustment tube. The upper end of the adjustment tube is provided with an accommodating notch 41. The accommodating notch 41 is arranged at intervals along the circumference of the adjustment tube. The arc angle between adjacent accommodating notches 41 is 120°. The lower connecting member 34 is composed of a lower end face gear. The upper end face gear and the lower end face gear form a clutch mechanism.

[0035] like Figure 5 、 6As shown in Figures 7 and 8, an arcuate groove 42 is provided on the upper end surface of the adjusting tube, and a ball 38 is provided on the assembly foot 37, and the ball 38 cooperates with the arcuate groove 42. There are three assembly feet 37 and three accommodating notches 41. When the clamping body 31 is in the initial state, the assembly feet 37 and the arcuate groove 42 are staggered at 90°. After the upper connecting member 14 and the lower connecting member 34 are connected by transmission, the assembly foot 37 rotates 90°, and when it runs to the accommodating notch 41, it is driven by the adjustment spring 35 to fall into the accommodating notch 41, thereby separating the upper connecting member 14 and the lower connecting member 34. The constraint lifting and adjusting mechanism can be specifically composed of a constraint lifting and adjusting cylinder 43, and the adjusting tube is installed on the piston rod of the constraint lifting and adjusting cylinder 43, and the adjusting tube is adjusted to be lifted and lowered by the constraint lifting and adjusting cylinder 43. Since four notches 32 on the supporting surface correspond to the connecting claws 61, the angle between adjacent notches 32 is 90°. This allows the lower connecting member 34 to be reliably adjusted to rise to a high position for reliable transmission connection with the upper connecting member 14 when the adjusting member is in the high position, and to be reliably separated from the upper connecting member 14 after rotating 90°. The auxiliary adjusting member 36 can be specifically composed of an auxiliary adjusting gear provided on the clamping body 31. A fixedly mounted arc-shaped rack 50 is provided on the path of the clamping body 31 running from the adjustment station to the unloading station or from the unloading station to the loading station. During the rotation of the turntable, the arc-shaped rack 50 engages with the auxiliary adjusting gear to cause the clamping body 31 to rotate 90° in the opposite direction, thereby restoring the clamping body 31 to its initial state when the clamping body runs to the loading station again.

[0036] The method for using the above-mentioned conveying device provided by the present invention for assembling and conveying LED lamps is as follows: a loading station, an adjustment station and an unloading station are sequentially arranged on the conveying line along the conveying direction, and the light-transmitting cover body 60 is supported by various supporting devices arranged at intervals on the conveying line. The light-transmitting cover body 60 to be assembled is arranged on the supporting device at the loading station. At this time, the connecting claws 61 on the light-transmitting cover body 60 are supported and dragged by the supporting surface, and the supporting device conveys the light-transmitting cover body 60 to the adjustment station. At this time, the pressing unit descends to clamp or press the light-transmitting cover body 60, and then the rotating adjustment shaft 10 is adjusted to rotate, driving the light-transmitting cover body 60 to rotate. After the light-transmitting cover body 60 rotates, when the connecting claw 61 moves to the recessed portion 32 provided on the supporting surface, the light-transmitting cover body 60 moves downward, and the upper connecting member 14 and the lower connecting member 34 in the high position are connected by transmission, thereby driving the clamping body 31 to rotate together. After the clamping body 31 rotates 90°, the lower connecting member 34 moves downward, and the transmission between the upper connecting member 14 and the lower connecting member 34 is disconnected, thereby adjusting the light-transmitting cover body 60 to the required state. After the pressing unit moves upward, the supporting device is adjusted to run to the unloading station, and the light-transmitting cover body 60 at the unloading station can be taken out and assembled.

[0037] Preferably, after the connecting claw 61 falls into the recess 32, the light-transmitting cover 60 and the pressure plate 21 are separated. That is, the height to which the light-transmitting cover 60 descends is less than the height to which the upper transmission member 14 descends. This facilitates the separation of the clamping unit 20 and the light-transmitting cover 60. Once the upper transmission member 14 is in transmission connection with the lower transmission member 34, it no longer has the freedom to continue descending. That is, the upper transmission member 14 does not continue descending as the lower transmission member 34 descends. Each adjustment rotation of the adjustment shaft 10 rotates at least one full revolution.

[0038] In summary, the above solution provided by the present invention can effectively realize the reliable transportation and state adjustment of the light-transmitting cover 60 , ensure the automatic assembly of the LED lamp, and the damage rate of the light-transmitting cover 60 is low.

[0039] The foregoing is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained herein shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
