Description

Technical Field

[0001] This invention relates to the field of electrical and electronic component manufacturing and testing technology, specifically to a fully automatic halogen tungsten lamp high-voltage application, rod cutting, rod grinding, and visual inspection equipment. Background Technology

[0002] The structure of the halogen tungsten lamp tube in the printer is roughly a cylindrical tube with a molybdenum rod extending from both ends. During the production process, the lamp tube needs to undergo several steps, including high-voltage testing to detect poor solder joints (Toshiba tests luminous flux with high voltage), visual inspection of brightness, cutting the rods (the molybdenum rods extending from both ends), grinding the rods, and visual inspection of the cutting rod length and the grinding effect. In existing technologies, these steps are generally performed separately, which is inefficient and has high labor costs. To improve operational efficiency, there is an urgent need in the market for a device that can integrate the above steps into a single set of equipment with a high degree of automation. Summary of the Invention

[0003] The problem to be solved by the present invention is to provide a fully automatic device for high voltage application, rod cutting, rod grinding and visual inspection of halogen tungsten lamps, which overcomes the shortcomings of the prior art.

Those skilled in the art can understand the specific meaning of the above terms in the present invention through specific circumstances.

[0060] This invention provides a fully automatic device for high-voltage application, rod cutting, rod grinding, and visual inspection of halogen tungsten lamps, such as... Figure 1 , 2 As shown, the chain conveyor includes loading station A, loading pitch transfer station B, workpiece alignment and air nozzle position detection station E, high-pressure optical flux meter detection station F, high-pressure vision inspection station H, laser cutting, grinding, and dust removal station J, vision inspection station K, unloading pitch transfer station L, unloading station M, and the chain conveyor with through-workpiece alignment and air nozzle position detection station E, high-pressure optical flux meter detection station F, high-pressure vision inspection station H, and laser cutting, grinding, and dust removal station J (see...). Figure 6 ), and electronic sensing elements and PLCs (not shown in the figure) installed in each of the above workstations and controlling the circuit systems of each of the above workstations.

[0061] Chain conveyors are used for the transfer of workpieces between workstations, such as... Figure 6 As shown, the conveyor chain of the chain conveyor has toothed grooves that correspond one-to-one with the workpieces, and the chain conveyor is equipped with multiple workpiece lifting mechanisms to cooperate with the above-mentioned workstation operations.

[0062] Among them, the workpiece alignment and nozzle position detection station E, the nozzle position detection station, the high-pressure optical flux meter detection station F, the high-pressure visual inspection station H, and the visual inspection station K are all equipped with defect removal stations. The structures of each defect removal station are the same. Taking the second defect removal station at the high-pressure optical flux meter detection station F as an example, Figure 9 As shown, the system includes a defective product discharge fixture G1 and a defective product receiving tray G2 for collecting defective products. The defective product discharge fixture G1 can move up and down under the action of a driving device, while the defective product receiving tray G2 can move horizontally under the action of a driving device. After a defective product is detected at the inspection station, the defective product discharge fixture G1 moves downward to pick up the defective workpiece from the chain conveyor. The defective product receiving tray G2 moves horizontally to below the defective product discharge fixture, and the defective product discharge fixture G1 places the defective workpiece into the defective product receiving tray G2. The defective product receiving tray G2 then resets.

[0063] The workpieces to be processed are placed in the lamp trays, and multiple lamp trays are stacked at the loading station. The workpieces then enter the fully automated halogen tungsten lamp high-pressure, rod cutting, rod grinding, and vision inspection equipment from the loading station. Figure 3 , Figure 4 As shown, the loading station includes a lamp tray placement platform, a loading conveyor belt A1, and a loading workpiece transfer unit. The loading conveyor belt A1 is located on one side of the lamp tray placement platform, and the loading workpiece transfer unit is located above the lamp tray placement platform. Its transfer range extends from the loading conveyor belt A1 to the loading variable-pitch transfer station. The lamp tray placement platform is used to stack lamp trays A2 containing lamps. The loading workpiece transfer unit includes a guide rail A3 aligned with the workpiece orientation and a longitudinal moving component A4 located on the guide rail A3 and capable of moving along the direction of the guide rail A3. The longitudinal moving component A4 can move up and down under the action of the drive equipment. The lower end of the longitudinal moving component A4 has a loading workpiece transfer clamp A5, as shown. Figure 5 As shown, the bottom of the workpiece transfer fixture A5 has multiple workpiece clamps A7 arranged side by side for clamping workpieces. The two sides of the workpiece transfer fixture A5 have lamp tube tray clamping plates A6 driven by a power unit for clamping lamp tube trays A2. The other two sides of the workpiece transfer fixture A5 have alignment plates A8 driven by a drive device for aligning workpieces in lamp tube trays A2.

[0064] The operator manually places multiple stacked lamp trays A2 containing workpieces onto the lamp tray placement table. The workpiece transfer fixture A5 picks up the workpieces from the lamp trays A2 and moves them along the guide rail to the loading variable pitch transfer station B. The workpieces are placed in the loading variable pitch transfer station B by the workpiece transfer fixture A5. After the workpiece transfer fixture A5 returns to the lamp tray placement table, it picks up the empty lamp trays A2 and places them on the loading conveyor belt A1. Then it returns to the lamp tray placement table to repeat the workpiece loading action.

[0065] like Figure 3 As shown, the loading and variable-pitch transfer station includes a loading track aligned with the workpiece's direction, a moving feeding variable-pitch frame B3, and a fixed variable-pitch frame B2. The moving feeding variable-pitch frame B3 includes a liftable variable-pitch frame base plate B4 driven by a drive device, and two opposing variable-pitch frame support side plates B5 located on the base plate B4. The upper edge of the support side plates B5 has multiple holding slots corresponding to the workpieces. The cross-section of the holding slots is an inverted triangular structure, and the spacing between the bottoms of adjacent holding slots is the same as the spacing of the toothed grooves on the chain conveyor. The base plate B4 is located on the loading track and can be driven by the drive device. Driven by the equipment, it moves along the feeding track. One end of the feeding track extends into the end of the chain conveyor. The fixed pitch frame B2 is fixed above the feeding track. The fixed pitch frame B2 has placement slots that correspond one-to-one with the workpieces. The spacing at the bottom of the placement slots is the same as the spacing of the workpieces in the lamp tray A2. The workpiece is placed in the placement slot on the fixed pitch frame B2 by the feeding workpiece transfer fixture A5, and then moved to the tooth groove of the chain conveyor by the moving feeding pitch frame B3. The chain conveyor drives the workpiece into the workpiece centering station in the workpiece centering and air nozzle position detection station.

[0066] like Figure 7 As shown, the centering station includes two primary centering and shaping plates E1 and two secondary centering and shaping plates E2 arranged opposite to each other. Both the primary centering and shaping plates E1 and the secondary centering and shaping plates E2 can be moved up and down, or towards each other or away from each other by the drive equipment. The primary centering and shaping plate E1 is a flat plate structure that can abut against the two ends of the workpiece and the end of the molybdenum rod. The upper surface of the secondary centering and shaping plate E2 is provided with multiple slots at intervals. Each slot can correspond to a workpiece. The molybdenum rods extending from both ends of the workpiece lifted by the lifting mechanism can pass through the slots. The secondary centering and shaping plate E2 can abut against the two ends of the tubular structure of the workpiece.

[0067] like Figure 8As shown, the nozzle position detection station includes two sets of opposing lower roller groups E5, an upper roller group E4 positioned above the lower roller groups E5, and a nozzle position sensor E3. Both the upper and lower roller groups E4 include multiple rollers and belts wrapped around them. The belts can contact the workpiece surface and rotate the workpiece due to friction. The lower roller group E5 is fixed to a lower roller frame, which is mounted on a lifting mechanism. The lower roller frame is lifted by the lifting mechanism to raise the workpiece to a position where it contacts the upper roller group E4. The workpiece rolls under the action of the upper and lower roller groups E4 and E5. The nozzle position sensor E3 detects whether the workpiece is correctly positioned relative to the nozzle to determine if its placement orientation is correct. Workpieces with incorrect placement orientation are discharged through the first defective discharge station behind the workpiece alignment and nozzle position detection station E5. The upper roller assembly E4 is fixed on the upper roller frame, which is slidably connected to a slide rail of the air nozzle detection station perpendicular to the workpiece direction, so as to adjust the coordinates of the upper roller assembly E4 to make it suitable for workpieces of various specifications.

[0068] The high-voltage luminous flux meter testing station F and the high-voltage visual inspection station H are both located inside light shields. Station F is used to check for cold solder joints at both ends of the workpiece tube. This step is also known in the industry as Toshiba high-voltage testing, and its function is similar to high-voltage inspection, except that Toshiba's high-voltage testing is not visual inspection, but rather detection of the light emitted when powered on using a photocell. Each lamp tube corresponds to a luminous flux meter. Its structure includes a high-voltage luminous flux leveling frame F4, a high-voltage luminous flux centering and shaping frame F5, a power-on detection clamp F1, and a stabilizing clamp F2, as shown below. Figure 11 As shown, the structure of the high-voltage luminous flux leveling frame F4 is the same as that of the high-voltage luminous flux leveling frame, and the structure of the high-voltage luminous flux centering and shaping frame F5 is the same as that of the high-voltage luminous flux centering and shaping frame H3. The energized detection clamp F1 contains a luminous flux detector and multiple high-voltage luminous flux detection stations corresponding one-to-one with the molybdenum rods on the workpiece. The energized detection clamp F1 is opened and closed by a bidirectional cylinder. The stabilizing clamp F2 can move up and down under the action of the drive device. The lifting mechanism lifts the workpiece from... The chain conveyor rises, and the stabilizing clamp F2, in conjunction with the lifting mechanism, holds the workpiece in place. The energized detection clamp F1 clamps the molybdenum rods extending from both ends of the workpiece. After power is applied, the optical flux detector checks whether the workpiece has a poor weld. After the inspection is completed, the energized detection clamp F1 opens, the stabilizing clamp F2 rises, and the lifting mechanism descends, placing the inspected workpiece back onto the chain conveyor. The chain conveyor continues to transport the workpiece to the high-pressure visual inspection station. Workpieces that fail the inspection will be picked up through the second defective discharge station G.

[0069] like Figure 12 , Figure 13As shown, the high-pressure visual inspection station H includes two high-pressure leveling frames, two high-pressure centering and shaping frames H3 arranged opposite each other, two sets of energized high-pressure clamping blocks H1 arranged opposite each other, and a high-pressure inspection camera. The two high-pressure leveling frames can move up and down synchronously under the drive of the driving device. The two high-pressure centering and shaping frames H3 can move up and down synchronously, opposite each other, or away from each other under the drive of the driving device. The high-pressure centering and shaping frames H3 are located between the high-pressure leveling frames and the energized high-pressure clamping blocks H1. The upper edge of the high-pressure leveling frames has multiple inclined edges arranged side by side. The structure of the high-pressure centering and shaping frames H3 is consistent with that of the workpiece centering station. The secondary centering and shaping plate E2 has the same structure. Multiple high-pressure stations, each corresponding to a molybdenum rod on the workpiece, are set inside the energized high-pressure clamping block H1. The energized high-pressure clamping block H1 is controlled to open and close by a bidirectional cylinder H2. A high-pressure detection camera is positioned above the area between the energized high-pressure clamping blocks H1. The high-pressure visual inspection station can detect any incomplete welds at both ends of the workpiece and whether the brightness of the light source inside the workpiece is up to standard. The energized high-pressure clamping block H1 clamps the molybdenum rods at both ends of the workpiece conveyed by the chain conveyor. After energizing the workpiece, the high-pressure detection camera inspects it. Unqualified products are picked up at the third defective discharge station I. Qualified workpieces continue to be conveyed by the chain conveyor to the laser cutting, grinding, and dust removal station J.

[0070] Laser cutting, grinding, and dust removal station J is used to cut the molybdenum rods extending from both ends of the workpiece to ensure that the length of the extended molybdenum rods meets the requirements, such as... Figure 14 As shown, the laser cutting, grinding, and dust removal station J includes a laser cutting machine J3, a lifting frame J5, a side clamping plate J6, an upper pressure plate, a grinding belt J7, and an air blowing nozzle structure, as follows: Figure 16 As shown, the laser cutting machine J3 is mounted on the transverse guide rail J2, which is slidably connected to the longitudinal guide rail J1. The laser cutting machine J3 can move up and down under the action of the drive device. Figure 15 As shown, the upper clamping plate and upper pressure plate of the side clamping plate J6 can move up and down under the action of the driving device. The side clamping plate J6 is used to clamp the ends of the molybdenum rods at both ends of the workpiece, and the upper pressure plate is used to cooperate with the lifting mechanism to press down the middle of the workpiece. The lifting frame J5 has a assisted rotating roller. The lifting frame J5 cooperates with the grinding belt J7 to grind the molybdenum rods on the workpiece after laser cutting. The air blowing nozzle structure is used to blow away the ground molybdenum rods. The workpiece is lifted from the chain conveyor by the lifting mechanism. The side clamping plate J6 clamps the two ends of the workpiece, and the lower pressure plate presses down the middle of the workpiece to keep the workpiece stable during cutting. The laser cutter J3 cuts the molybdenum rods at both ends of the workpiece. Then the lifting mechanism sinks down to put the workpiece back on the chain conveyor. The workpiece moves with the chain conveyor to below the grinding belt. The lifting mechanism lifts the workpiece again until the molybdenum rods are in contact with the grinding belt. Figure 18As shown, the lifting mechanism here has an auxiliary rotating roller J10 that drives the workpiece to rotate, and its structure is similar to... Figure 8 Similar to the process described above, the cutting area of ​​the molybdenum rod is ground using a sanding belt. After grinding, the workpiece continues to move via a chain conveyor to the air blowing nozzle structure, where the dust adhering to the ground area of ​​the molybdenum rod is blown off. Dust collection equipment is installed at the laser cutting area, sanding area, and air blowing nozzle structure of this station to collect the dust generated during laser cutting and air blowing. The dust collection equipment includes a suction pipe J8, a collection box, and a negative pressure pump.

[0071] The workpiece enters the vision inspection station K via a chain conveyor. The vision inspection station is used to check whether the length of the cut molybdenum rod is up to standard and whether the grinding degree of the molybdenum rod is up to standard. Figure 19 As shown, the visual inspection station K includes two sets of upper light sources K1, two sets of lower light sources K2, and an inspection camera K3. The upper light sources K1 and lower light sources K2 are arranged opposite to each other. The upper light source K1 has a ring structure, and the inspection camera K3 is set inside the upper light source K1.
