Description

Technical Field

[0001] This utility model relates to the field of lamp aging testing, specifically a multi-station automatic lamp loading and unloading aging testing line. Background Technology

[0002] A light bulb is a lighting device that converts electrical energy into light energy. The manufacturing process of a light bulb involves multiple steps: from making the glass shell, to installing the light-emitting components, to filling with a specific gas (if necessary), to welding the base, and finally sealing it. To ensure that every light bulb leaving the factory has good quality and performance, aging tests are conducted on each bulb after production and assembly. In this stage, the bulb is lit for a period of time under simulated real-world conditions to evaluate its stability and lifespan. This not only filters out products that may fail in the short term but also provides manufacturers with valuable data to help optimize product design and manufacturing processes.

[0003] Chinese patent document "CN221667095U, an LED lamp testing device" includes: a worktable with two symmetrical sliding grooves; a testing component disposed on the worktable; a sliding mechanism disposed within the sliding grooves; a lifting cylinder disposed on the sliding mechanism; a placement component including a placement frame disposed at the output end of the lifting cylinder and having a placement through hole, a rotary motor disposed on the placement frame, a rotary shaft driven and connected by the rotary motor, a drive gear disposed on the rotary shaft, a gear ring rotatably disposed on the placement frame and meshing with the drive gear, and a plurality of support blocks slidably disposed on the placement frame and having protrusions, the gear ring having a sliding groove for the protrusions to slide and for driving the support blocks to move inward or outward when the gear ring rotates; an LED lamp abutting against the support blocks; and a controller disposed on the worktable and controlling the connected electrical equipment.

[0004] The equipment can only test one LED at a time. When facing large-scale production, more manpower and time are needed to perform multiple individual testing operations, which not only increases production costs but also reduces the flexibility and response speed of the production line. Utility Model Content

[0005] The purpose of this invention is to provide an aging test line with multi-station automatic lamp loading and unloading to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An aging test line with multi-station automatic lamp loading and unloading includes a frame with an annular conductive rail. An electrical box electrically connected to the annular conductive rail is located inside the frame. Multiple lamp loading test carriages are electrically connected to the annular conductive rail. A drive mechanism for moving the lamp loading test carriages along the annular conductive rail is located on the inner side of the annular conductive rail. Four detection devices are located on the top of the frame, symmetrically arranged in pairs on the inner side of the frame. The detection ends of the detection devices are located above the lamp loading test carriages. An automatic loading device and an automatic unloading device with identical structures are symmetrically arranged on one side of the frame.

[0008] Furthermore, the drive mechanism includes four top plates, which are respectively located at the four corners of the top of the frame. Each of the four top plates is rotatably connected to a synchronous pulley. The frame is equipped with a synchronous motor that is connected to the synchronous pulleys. The four synchronous pulleys are connected by a synchronous belt, which is connected to the lamp loading test vehicle.

[0009] Furthermore, the lamp loading test vehicle includes a conductive tray, the bottom of which is electrically in contact with an annular conductive rail. The bottom of the conductive tray is provided with four rollers, and the conductive tray slides in cooperation with the annular conductive rail through the four rollers. The conductive tray is provided with six mounting holes for installing lamps, and the bottom of the conductive tray is also provided with two sliding blocks that slide in cooperation with the annular conductive rail.

[0010] Furthermore, the detection device includes a bracket, on which a downward-facing photoelectric sensor is mounted, and the photoelectric sensor is electrically connected to an electrical box.

[0011] Furthermore, the automatic feeding device includes a conveyor belt and a support frame. The conveyor belt carries a lamp box that is placed manually. The lamp box has two placement positions for placing lamps. A movable slide is horizontally arranged on the support frame. A movable plate is provided on the movable end of the movable slide. Two lifting cylinders are symmetrically arranged on the movable plate. A fixed plate is installed on the lifting end of the two lifting cylinders. Two gripper cylinders are symmetrically installed at the bottom of the fixed plate. Two symmetrical gripping arms are connected to the working end of the gripper cylinders. A contoured rubber pad is provided on the gripping arm. The lamps on the lamp box are placed sequentially onto the lamp loading and testing vehicle through the gripping arms.

[0013] Furthermore, the conductive tray has an upwardly extending baffle on its outer edge.

[0014] The beneficial effects of this utility model are:

[0015] This invention allows for the simultaneous aging and testing of multiple lamps by setting up multiple lamp loading test vehicles on a circular guide rail, thus greatly shortening the lamp testing cycle.

[0016] By symmetrically setting up four detection devices in pairs, the system is automatically activated when the lighting test vehicle passes by, performing multiple tests on the lighting fixtures. This effectively reduces the errors that may occur in a single test and provides more reliable and accurate test results.

[0017] By applying automatic feeding and unloading devices, this multi-station aging line automatic lamp detection device not only significantly reduces reliance on manual operation and lowers labor costs, but also effectively avoids the possibility of workers directly contacting the circular conductive rail, thereby eliminating the risk of electric shock accidents caused by accidental contact with live parts and significantly improving the safety of the production process.

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] Please refer to Figure 1-7 ;

[0029] An aging test line with multi-station automatic lamp loading and unloading includes a frame 1, on which a ring-shaped conductive rail 2 is mounted. An electrical box (not shown) electrically connected to the ring-shaped conductive rail 2 is located inside the frame 1. The electrical box provides the necessary power support for the entire device. Multiple lamp loading test carts 3 are electrically connected to the ring-shaped conductive rail 2. By placing the lamps on these test carts, the power provided by the electrical box can be transmitted to each lamp loading test cart 3 through the ring-shaped conductive rail 2, ensuring a stable current supply for the lamps, thus enabling smooth startup and continuous illumination. A drive mechanism 4 is located on the inner side of the ring-shaped conductive rail 2 to move the lamp loading test carts 3 along the ring-shaped conductive rail 2. Four detection devices 5 are located on the top of the frame 1. The testing devices 5 are symmetrically arranged in pairs on the inner side of the frame 1. The testing end of the testing device 5 is located above the lamp loading test vehicle 3. When the lamp loading test vehicle 3 passes directly below the corresponding testing device 5, the testing device 5 will be automatically activated to test the lamp. Multiple testing devices 5 can reduce errors. On one side of the frame 1, there are symmetrically arranged automatic feeding devices 6 and automatic unloading devices 7 with the same structure. The automatic feeding device 6 is located at the beginning of the aging test line, and the automatic unloading device is located at the end of the aging test line. Before the test starts, the automatic feeding device 6 can automatically place the lamp to be tested onto the lamp testing vehicle. After the test is completed, the automatic unloading device 7 is responsible for automatically removing the lamp that has completed the test. This not only improves the testing efficiency but also reduces manual operation and lowers labor costs.

[0030] In this embodiment, the drive mechanism 4 includes four top plates 41, which are respectively located at the four corners of the top of the frame 1. Synchronous pulleys 42 are rotatably connected to the four top plates 41. A synchronous motor (not shown in the figure) is provided inside the frame 1 and is driven by the synchronous pulleys 42. The four synchronous pulleys are connected by a synchronous belt 43, which is connected to the lamp loading test vehicle 3. Preferably, a connecting block is provided on the side of the synchronous belt 43 corresponding to the lamp loading test vehicle 3 to fix them together. When the synchronous belt 43 moves, it drives the connecting block and drives the lamp loading test vehicle 3 to move together. When the lamp is tested, the automatic feeding device 6 places the lamp on the lamp loading test vehicle 3. Then, the synchronous motor starts and drives one of the synchronous pulleys 42 to rotate. This rotating synchronous pulley 42 is transmitted to the other three synchronous pulleys 42 through the synchronous belt 43, so that they rotate synchronously. With the movement of the synchronous belt 43, the lamp loading test vehicle 3 moves smoothly along the annular conductive rail 2 and passes under each testing device 5 in sequence to ensure that each lamp can undergo comprehensive aging test.

[0031] In this embodiment, the lamp loading test vehicle 3 includes a conductive tray 31. The bottom of the conductive tray 31 is in electrical contact with the annular conductive rail 2, enabling the annular conductive rail 2 to transmit power to the conductive tray 31. The conductive tray 31 includes at least one power line (not shown in the figure), which provides the power required by the lamp to be tested placed on the conductive tray 31 during aging testing. The bottom of the conductive tray 31 is provided with four rollers 32, which slide in cooperation with the annular conductive rail 2. The conductive tray 31 is provided with six mounting holes 33 for mounting lamps. Preferably, the lamp is a direct-insertion bulb. When the automatic feeding device places the lamp into the mounting hole, the lamp can be powered on and illuminated by directly inserting the bulb into the mounting hole. The bottom of the conductive tray 31 is also provided with two sliding blocks 34 that slide in cooperation with the annular conductive rail 2. Through the combined action of these two sliding blocks 34 and the four rollers 32, the conductive tray 31 can not only move smoothly on the annular conductive rail 2, but also effectively prevent derailment.

[0032] In this embodiment, the detection device 5 includes a bracket 51, on which a downward-facing photoelectric sensor 52 is mounted. The photoelectric sensor 52 is electrically connected to the electrical box. The specific detection method is described in technical document "CN104166106B, Horizontal Cyclic Aging System for Lamp Holders and Fixtures". During the aging test, when the lamp loading test vehicle 3 carries the aged lamps to the area below the detection device 5, the photoelectric sensor 52 automatically activates to detect the lamp's luminous state. If the lamp fails to emit light normally or exhibits flickering, the photoelectric sensor 52 records this anomaly and transmits the detection data to the computer system in real time. This data is then used for further analysis and recording to evaluate the aging performance and quality of the lamps, as well as for subsequent improvements to lamp production technology.

[0033] In this embodiment, the automatic feeding device 6 includes a conveyor belt 60 and a support frame 61. The conveyor belt 60 is electrically connected to the electrical box. A lamp box 62, which is placed manually, is conveyed on the conveyor belt 60. The lamp box 62 has two placement positions 621 for placing lamps. A movable slide 63 is horizontally arranged on the support frame 61. A movable plate 64 is provided on the movable end of the movable slide 63. Two lifting cylinders 65 are symmetrically arranged on the movable plate 64. The lifting end of the lowering cylinder 65 is fitted with a fixing plate 66. Two gripper cylinders 67 are symmetrically installed at the bottom of the fixing plate 66. The working end of the gripper cylinder 67 is connected to two symmetrical gripping arms 68. The gripping arms 68 are equipped with contoured rubber pads 69 to ensure safety and stability when gripping the lamps, while avoiding hard contact with the lamp glass and preventing damage to the lamp cover. The lamps on the lamp box 62 are placed onto the lamp loading test vehicle 3 in sequence through the gripping arms 68.

[0034] During operation, the conveyor belt 60 moves the lamp holder 62, containing the lamps, directly beneath the gripper arm 68. At this point, each lamp corresponds to one of the two gripper cylinders 67. Next, the lifting cylinder 65 lowers, causing the fixing plate 66 and the two gripper cylinders 67 to move downwards. As the gripper cylinders 67 descend, the two gripper arms 68 gradually open, ready to grasp the lamps. Once the clamping arm 68 reaches the predetermined position, the gripper cylinder 67 is activated, and the two clamping arms 68 close and firmly grasp the lamp. Subsequently, the lifting cylinder 65 rises, bringing the clamping arm 68 holding the lamp back to its initial height. The moving slide 63 drives the moving plate 64 to move horizontally, so that the clamping arm 68 is accurately aligned with the mounting hole 33 on the lamp loading test vehicle 3. Finally, the lifting cylinder 65 descends again, placing the lamp onto the lamp loading test vehicle 3. After placement, the clamping arm 68 is released, and the lifting cylinder 65 drives the clamping arm 68 back to the starting position, preparing for the next round of operation.

[0035] In this embodiment, the automatic unloading device 7 includes a second conveyor belt 70 and a second support frame 71. The second conveyor belt 70 is electrically connected to the electrical box. The second conveyor belt 70 carries a second lamp box 72 that is placed manually. The second lamp box 72 has two placement positions 721 for placing lamps. The second support frame 71 has a horizontally arranged movable slide 73. The movable end of the movable slide 73 has a movable plate 74. The movable plate 74 has two symmetrically arranged lifting cylinders 75. The lifting ends of the two lifting cylinders 75 are fitted with a fixed plate 76. The bottom of the fixed plate 76 has two symmetrically arranged gripper cylinders 77. The working ends of the gripper cylinders 77 are connected to two symmetrical gripping arms 78. The gripping arms 78 are provided with contoured rubber pads 79. The lamps on the lamp loading test vehicle 3 are placed onto the second lamp box 72 in sequence through the gripping arms 78 and then transported away by the second conveyor belt 70.

[0036] After the lamp testing is completed, conveyor belt 270 transports the empty lamp box 272 directly below clamping arm 278, ready to receive the tested lamps. Moving slide 273 moves moving plate 274 horizontally, aligning clamping arm 278 precisely with the lamps on the lamp loading test vehicle 3. Then, the lifting cylinder 275 lowers, causing the fixed plate 276 and two gripper cylinders 167 to move downwards. As gripper cylinders 277 descend, the two clamping arms 278 gradually open, ready to grasp the lamps. When clamping arms 278 reach the predetermined position, gripper cylinders 277 activate, and the two clamping arms 278 close. The system firmly grips the lamp, and the lifting cylinder 2 75 rises, bringing the clamping arm 2 78 holding the lamp back to its initial height. Then, the moving slide 2 73 drives the moving plate 2 74 to move horizontally again, so that the clamping arm 2 78 is accurately aligned with the placement position 2 721 on the lamp box 2 72. Finally, the lifting cylinder 2 75 descends again, placing the lamp smoothly on the placement position 2 721 of the lamp box 2 72. When both lamps have been placed, the conveyor belt 2 70 operates, transporting the lamp box 2 72 filled with lamps away and conveying a new empty lamp box 2 72 directly below the clamping arm 2 78, ready to receive the next set of lamps.

[0037] Since this device is used for aging testing of large batches of lamps, the simultaneous illumination of multiple lamps will produce extremely high brightness, which may damage the eyes of the operators. Therefore, an upward-extending baffle 35 is provided on the outer edge of the conductive tray 31. The baffle 35 can effectively block the strong light emitted by the lamps, protect the operator's vision from being affected, ensure the safety of the staff's eyes, and reduce the interference of strong light on the testing process, ensuring the accuracy and efficiency of the test.

[0038] In addition, the upper ends of the mounting holes 33 on the conductive tray 31, the placement position 621 of the first lamp box 62, and the placement position 721 of the second lamp box 72 form a conical inlet. The conical inlet helps guide the lamps to enter the corresponding installation positions more smoothly, reduces the difficulty of alignment during placement, improves the accuracy and efficiency of automated operation, and avoids the risk of damage caused by misplacement or positional deviation.
