Description

Technical Field

[0001] This invention relates to the field of electrical and electronic component manufacturing and testing technology, specifically to a fully automatic aging and power measurement device for halogen tungsten lamps. Background Technology

[0002] The failure rate of electrical and electronic components during use is a function of usage time. In the initial stage of use, the failure rate rises sharply over time, then drops sharply, maintaining a low failure rate for the remainder of its lifespan until the later stages, when it rises again. This is known as the "bathtub curve" of product failure rate. To identify products with high failure rates in the early stages of use, a quality control point in the product manufacturing process—the aging process—is implemented. This simulates the product's usage conditions, allowing it to operate for a period of time, and discarding any products that fail during this period to ensure the quality of the products leaving the factory. Withstand voltage testing is crucial for product and user safety, so it is generally conducted after aging to facilitate the detection of faulty products. Halogen tungsten lamps, as electronic components, also require this type of testing before leaving the factory. Currently, there is no highly efficient, integrated, fully automated aging and power measurement equipment. Summary of the Invention

[0036] The present invention will be further described in detail below with reference to specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. In the description of the present invention, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description, and do not 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 a limitation of the present invention. In the description of the present invention, it should be noted that unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention through specific circumstances.

[0037] like Figure 1 , 2 As shown, the present invention provides a fully automatic aging and power measurement device for halogen tungsten lamps, including a feeding and conveying unit A, a feeding and direct vibration unit B, an aging and power measurement unit C, a feeding unit D, a discharging unit E, and a defective discharge unit F. The feeding and conveying unit A, the feeding and direct vibration unit B, the aging and power measurement unit C, the feeding unit D, the discharging unit E, and the defective discharge unit F are all controlled by a PLC.

[0038] like Figure 3 As shown, the feeding conveyor unit A and the feeding direct vibration unit B are interconnected. The feeding conveyor unit A sends the halogen tungsten lamps A3 (workpieces) to the feeding direct vibration unit B in batches. The feeding direct vibration unit B is used to lay the stacked halogen tungsten lamps A3 flat and send them sequentially to the next detection unit at intervals.

[0039] The feeding and conveying unit A includes a conveyor belt A1 located on a conveyor belt frame A4. Multiple dividing baffles A2 are set at intervals on the conveyor belt A1. Halogen tungsten lamps A3 are placed in the dividing baffles A2 respectively and are slowly fed into the feeding and conveying unit B in batches. The bottom of the conveyor belt frame A4 has an adjusting slide rail A5, which can be used to adjust the width of both sides of the conveyor belt A1 to make it suitable for workpieces of different specifications.

[0040] like Figure 4As shown, the feeding vertical vibration unit B includes a guide plate B1, two fixed outer frame plates B3 arranged opposite each other, two inner frame plates B4 driven by cylinders and movable vertically, two parallel and spaced guide rods B5, and a feeding rack B8 driven by cylinders and capable of horizontal reciprocating along the workpiece flow direction. The guide plate B1 is located at the unloading end of the conveyor belt A1. The guide plate B1 is inclined to receive the halogen tungsten lamps A3 falling from the conveyor belt A1 and to prevent the halogen tungsten lamps A3 from falling, thereby controlling the accumulation height of the halogen tungsten lamps A3 at the tail end of the guide plate B1. A lifting block driven by a cylinder and movable vertically is provided at the tail end of the guide plate B1. The lifting block is used to lift the halogen tungsten lamps A3 at the tail end of the guide plate B1 to the top of the outer frame plates B3. The tops of both the outer frame plates B3 and the inner frame plates B4 have stepped teeth, with the supporting edge of the teeth being inclined. The frame plate B3, in conjunction with the vertically moving inner frame plate B4, allows the stacked halogen lamps A3 to be conveyed in small batches and laid out flat onto the guide rod B5. Vertically movable stop blocks B6 are installed at the middle and outer ends of the guide rod B5 to control the speed at which the halogen lamps A3 pass through, preventing localized accumulation. A limiting pressure block B7 is installed above the end of the guide rod B5 to ensure that each halogen lamp A3 is placed onto the feeding rack B8 at the end of the guide rod B5. The feeding rack B8 includes two opposing frames with multiple slots on top corresponding to halogen lamps A3. Each slot can hold one halogen lamp A3. Once the slots are full, the feeding rack B8 moves horizontally to the aging and power measurement unit C under the action of a driving element. Sensors for feedback signals are installed at the end of the guide plate B1, and at the middle and end of the guide rod B5.

[0041] like Figure 5 , Figure 6As shown, the aging and power measurement unit C includes a feeding belt C1 that runs through the entire aging and power measurement unit C. The feeding belt C1 has slots corresponding one-to-one with halogen tungsten lamps A3, each slot capable of holding one halogen tungsten lamp A3. One end of the feeding belt C1 receives workpieces fed onto it from the feeding frame B8. A sensing element is located at the limiting block B7. When a workpiece is detected at one end of the feeding belt C1, the feeding frame B8 lowers, causing the workpiece to fall into a slot on the feeding belt C1. Then, the slot on the feeding belt C1 moves horizontally. The feeding belt C1 has a [missing information - likely referring to a specific component or feature] at a position before entering the aging and voltage measurement assembly. A shaping plate C2, driven by a cylinder, moves in opposite directions to align the two ends of the halogen tungsten lamp A3. Then, a feeding belt C1 sequentially feeds the workpiece into three aging components and one power measurement component arranged side-by-side. The aging and power measurement components have identical structures, each with eight stations. Each component includes a mounting frame C4, a bidirectional cylinder C5, and eight parallel inspection stations C6 composed of upper and lower clamping blocks. The bidirectional cylinder C5 is fixed to the mounting frame C4 and drives the upper and lower clamping blocks to clamp the metal rods at both ends of the halogen tungsten lamp A3. The contact points between the upper and lower clamping blocks and the metal rods have conductive structures. The voltage supplied to the halogen tungsten lamp by the three aging components increases at the aging stations. The voltage is measured at the midpoint of the aging station values ​​at the inspection stations, and the voltage can be adjusted in segments between 0V and 300V. The workpiece fed into the aging and power measurement component by the feeding belt C1 is clamped by the upper and lower clamping blocks inside the component. After the aging or power measurement step is completed, the upper and lower clamping blocks open, and the workpiece returns to the tooth groove of the feeding belt C1 and continues to move forward along the workpiece movement direction. The workpiece coming out of the power measurement component moves with the feeding belt C1 to the defective discharge unit F.

[0042] A protective cover 2 needs to be added at the aging and power measurement unit C. A cooling and exhaust device should be installed inside the protective cover 2 to remove heat in a timely manner.

[0043] like Figure 7As shown, the defective discharge unit F includes a defective discharge mounting frame F1, a collection tray F2, a defective discharge cylinder F3, and a receiving cylinder F5. Both the defective discharge cylinder F3 and the receiving cylinder F5 are fixed on the defective discharge mounting frame F1. The telescopic rod end of the defective discharge cylinder F3 has four clamps F4 arranged at intervals and staggered. The four clamps F4 are arranged in pairs, and the two pairs of clamps F4 correspond to the halogen tungsten lamps A3 at stations one, three (five, seven) and two, four (six, eight) respectively. The clamps F4 move up and down under the drive of the defective discharge cylinder F3. The receiving cylinder F5 is connected to the collection tray F2 and drives the collection tray F2 to move in the horizontal direction. The detection data from the aging and power measurement unit C is transmitted back to the PLC, recorded, and printed by the printing device 4 connected to the PLC. The detection data is saved in the PLC program. Abnormal data signals are transmitted to the defective product discharge unit F via electrical signals. The defective product discharge unit F picks up the defective products using the gripper F4. The collection tray F2 moves under the gripper F4 driven by the receiving cylinder F5 to collect the defective products. Qualified products will enter the unloading unit D driven by the feeding belt C1, and then enter the discharge unit E through the unloading unit D.

[0044] like Figure 8 The diagram shows the unloading unit D, which includes a base plate D1, a push-pull rod D6, two slide rods D4, and two push blocks D2. The slide rods D4 are positioned above the base plate D1, and the push-pull rod D6 is connected to the base plate D1. The push-pull rod D6 is driven by a driving element to move horizontally. The push blocks D2 are fixed to the base plate D1 by a lifting rod and are located outside the slide rods D4. The push blocks D2 have a push plate D3 that can move horizontally, with the push plate D3 facing the end of the base plate D1. The base plate D1 has a retractable stop rod D5, and a sensing element is located at the stop rod D5. Halogen lamps A3, falling from the feeding belt C1, slide down from slide bar D4. At this time, stop bar D5 extends to prevent them from falling further. When a certain number of workpieces accumulate at stop bar D5, push bar D5 pushes bottom plate D1 to a position close to discharge unit E. Stop bar D5 returns to its original position, push block D2 rises, and push plate D3 pushes the workpieces forward to guide frame E6 in tray E3 of discharge unit E. Push bar D6 pulls bottom plate D1 back to a position close to feeding belt C1. Stop bar D5 extends and repeats the above unloading action.

[0045] like Figure 9 As shown, the discharge unit E includes a pallet frame E8, on which multiple pallets E3 are placed at intervals from top to bottom. Belts E4 and pulleys E5 are provided on both sides of the pallet frame E8. Belts E4 are connected to the pallet frame E8, and pulleys E5 are driven by a motor E2. Guide posts E7 are provided on both sides of the pallet frame E8, and guide frames E6 are provided inside the pallets E3.

[0046] The embodiments of the present invention have been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made in accordance with the scope of the present invention should still fall within the patent coverage of the present invention.
