Description

Technical Field

[0001] This invention relates to the field of semiconductor silicon wafer inspection technology, specifically to a structure for improving the consumption of spotlights on a final appearance visual inspection stage and a method for reducing costs and increasing efficiency. Background Technology

[0002] The existing Osram 24V 250W spotlight bulbs on the surface inspection machine have heat dissipation issues. When visual inspectors examine silicon wafers for defects, the inspection station operates 24 hours a day, generating significant heat. If this heat cannot be dissipated promptly, it can lead to excessively high bulb temperatures, causing accelerated light decay, color temperature drift, short circuits in the base, and a significantly shortened lifespan. Current heat dissipation methods, such as small ventilation holes in the cover, have limited efficiency and are insufficient for high-power or enclosed environments.

[0003] Existing visual inspection table lighting technology generally suffers from the following problems: (1) The spotlight suffers severe wear and tear and has a short lifespan: High-power light-emitting elements (such as halogen lamps or high-power LEDs) generate a lot of heat when they are working.

[0004] Existing equipment often lacks efficient active heat dissipation measures or has an unreasonable heat dissipation structure design, resulting in heat accumulating inside the lamp cover.

[0005] Prolonged exposure to high temperatures accelerates the aging (light decay) of light-emitting elements and the wear and tear of filaments / substrates, leading to frequent spotlight failures and increasing equipment maintenance and consumable costs.

[0006] (2) Delayed heat dissipation affects lighting quality: Many devices only begin to dissipate heat after the lights are turned on, or stop dissipating heat immediately when the lights are turned off. This "thermal lag" phenomenon can cause the lights to heat up rapidly during the initial startup phase, or cause them to continue to be damaged after shutdown because residual heat cannot be dissipated.

[0007] Heat buildup can also lead to unstable light intensity or spectral shift, affecting the accuracy of visual inspection.

[0008] (3) Low testing efficiency and high labor intensity: Traditional visual inspection tables are mostly static, with products fixed in place. To inspect the sides and back of the product, operators must manually pick it up and flip or rotate it.

[0009] This "manual flipping" method not only increases the labor intensity of operators, leading to hand fatigue, but also reduces testing efficiency and makes it easy for products to fall or be scratched due to unstable hand grip.

[0010] (4) The equipment layout is not compact: In existing technologies, heat dissipation pipes and support structures are often designed separately, resulting in bulky equipment, loose structures, and excessive workshop space occupation. Summary of the Invention

[0011] This invention addresses the shortcomings of existing technologies by providing a structure and a cost-saving and efficiency-enhancing method for improving the consumption of spotlights in visual inspection tables. It features a compact structure, extended spotlight lifespan, reduced operating costs, stable testing environment, improved product quality, increased testing efficiency, and reduced labor intensity. It also solves the problem of rapid consumption and shortened lifespan of spotlights in visual inspection tables due to heat buildup during operation.

[0012] The above-mentioned technical problems of the present invention are mainly solved by the following technical solutions: A structure for improving the consumption of spotlights on a final appearance inspection table includes a frame, an inspection table at the top of the frame, an upper frame connected and fixed to the frame around the inspection table, a plurality of spotlights on the upper part of the upper frame, a heat sink for heat dissipation of the spotlights at the upper end of the upper frame, a support column between each spotlight and the top of the upper frame, and an air inlet pipe and an air outlet pipe fixed to the support column between the heat sink and the spotlights.

[0013] Preferably, the radiator includes an exhaust fan, one end of which is provided with an air supply pipe connected to an air inlet pipe, and the other end of which is provided with an air outlet pipe connected to an exhaust pipe.

[0014] Preferably, the spotlight includes a lampshade connected to an air inlet pipe and an air outlet pipe, a lamp head at the front end of the lampshade, a light-emitting element inside the lampshade, and a lamp body connected to the light-emitting element via a circuit between the lamp head and the light-emitting element.

[0015] Preferably, the frame is equipped with a heat sink and a power supply for powering the spotlight and the inspection table.

[0016] Preferably, the upper end of the inspection table is provided with several inspection fixtures arranged in a ring with equal spacing. The inspection table is driven by a motor to rotate and drive the inspection fixtures to rotate, so as to achieve inspection at different angles.

[0017] A method for reducing costs and increasing efficiency by improving the consumption of spotlights on a final appearance inspection table includes the following steps: Step 1: Equipment startup and preparation.

[0018] S1: Check if the power connection inside the rack is normal; check if the visual inspection fixture on the visual inspection table is installed securely, and ensure that the spotlight and heat dissipation pipes on the upper frame are properly connected.

[0019] S2: Connects the internal power supply of the rack to power the spotlight and heat sink.

[0020] S3: Turn on the exhaust fan in the radiator to remove the heat generated inside the spotlight.

[0021] Step 2: Product testing.

[0022] S4: After the cooling system has stabilized, turn on the spotlight. The light shines on the inspection table area, providing a high-brightness inspection environment.

[0023] S5: The operator places the product to be inspected on any of the visual inspection fixtures arranged in a ring on the visual inspection table.

[0024] S6: Start the motor of the visual inspection table to rotate. The rotation of the visual inspection table drives the visual inspection fixture and the product on it to rotate. During the rotation, the product passes through the illumination area of ​​the spotlight at different angles in sequence. The operator can stay still next to the workstation and clearly observe the appearance of the product from all sides without having to manually flip the product.

[0025] Step 3: Continuous monitoring and shutdown.

[0026] S7: Throughout the entire testing process, the radiator continues to operate, and cold air continuously flows through the air intake duct, lamp cover, and exhaust duct.

[0027] S8: After the test is completed, remove the product; repeat S5-S7 to test the next product.

[0028] S9: After the test is completed, turn off the spotlight first. Let the heatsink continue running for a while, then turn off the heatsink and the power supply of the entire machine.

[0029] As a preferred embodiment, the exhaust fan delivers airflow into the inlet duct through the supply duct. The airflow then enters the lamp housing through the inlet duct, directly carrying away the heat generated by the light-emitting element. After absorbing the heat, the airflow enters the exhaust duct and flows back to the radiator or is directly discharged through the outlet duct, thus establishing a cooling cycle before the spotlight starts working.

[0030] The present invention can achieve the following effects: This invention provides a structure and a method for improving the consumption of spotlights in a final appearance inspection table. Compared with the prior art, it has the advantages of compact structure, extended spotlight life, reduced usage cost, stable inspection environment, improved product quality, increased inspection efficiency and reduced labor intensity. It solves the problem of rapid consumption and shortened life of spotlights in inspection tables due to heat accumulation during operation.

[0031] Significantly extends spotlight lifespan and reduces operating costs: Active forced cooling: A forced air-cooling circulation system is constructed by setting up independent heat sinks, exhaust fans, and air inlet and outlet ducts connected to the lamp cover. Cool air directly enters the lamp cover and carries away the heat from the light-emitting elements, resulting in extremely high heat dissipation efficiency and effectively avoiding localized high temperatures.

[0032] Optimized control logic: The method specifies "turn on the heat sink first, then turn on the light" and "turn off the light first, then turn off the heat sink." This logic ensures that the lamps start up in low-temperature environments and cool down sufficiently after shutdown, eliminating the impact of sudden heating and cooling on the lamps, thereby significantly extending the lifespan of the spotlights and reducing replacement frequency and procurement costs.

[0033] Ensuring a stable testing environment and improving product quality: Continuous constant temperature cooling keeps the spotlight intensity stable, avoiding light decay or color temperature drift caused by excessive temperature. This ensures that the visual inspection station area always has a high-brightness, high-quality lighting environment, which helps operators to more accurately identify product appearance defects and prevent missed inspections.

[0034] Improve inspection efficiency and reduce labor intensity: Automated multi-angle inspection: The inspection table is driven by a motor to rotate, and with the help of three equally spaced inspection fixtures in a ring, the product can automatically display all sides during the rotation.

[0035] Hands-free operation: Operators can simply stand still at their workstations to observe, without manually flipping products. This not only significantly increases inspection speed (enabling continuous cyclical operation) but also significantly reduces operator fatigue.

[0036] Compact structure and reasonable layout: The radiator is placed at the top of the upper frame, and the air inlet and outlet ducts are fixed by the support column between the spotlight and the upper frame. This design cleverly utilizes the existing space, making the duct layout neat and beautiful, without taking up extra space, and the overall structure is stable.

[0037] Scientific airflow circulation design: It adopts a closed or directional circulation path of "air supply duct → air inlet duct → lamp cover → air exhaust duct → air outlet duct", which can accurately cool the heat-generating core (light-emitting element) and prevent hot air from running around inside the rack and affecting the life of other electrical components.

[0042] The technical solution of the invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0043] Example: Figure 1 , Figure 2 and Figure 3 As shown, a structure for improving the consumption of spotlights on a final appearance inspection table includes a frame 9, with an inspection table 8 at the top of the frame 9. Three equally spaced inspection fixtures 7 are arranged in a ring on the top of the inspection table 8. The inspection table 8 is driven by a motor to rotate, causing the inspection fixtures 7 to rotate and achieve inspection at different angles. An upper frame 1, connected and fixed to the frame 9, surrounds the inspection table 8. Three spotlights 6 are located on the upper part of the upper frame 1. Each spotlight 6 includes a lampshade 15, which is connected to an air inlet pipe 4 and an air outlet pipe 5. A lamp head 13 is located at the front end of the lampshade 15, and a light-emitting element 16 is located inside the lampshade 15. A lamp body 14, which is electrically connected to the light-emitting element 16, is located between the lamp head 13 and the light-emitting element 16. The upper frame 1 has a heat sink 3 for dissipating heat from the spotlight 6. The heat sink 3 includes an exhaust fan 11. One end of the exhaust fan 11 has an air supply pipe 10 connected to the air inlet pipe 4, and the other end of the exhaust fan 11 has an air outlet pipe 12 connected to the exhaust pipe 5. Support columns 2 are provided between the spotlight 6 and the top of the upper frame 1. An air inlet pipe 4 and an exhaust pipe 5, fixed to the support columns 2, are provided between the heat sink 3 and the spotlight 6. The frame 9 contains the heat sink 3 and a power supply for powering the spotlight 6 and the inspection table 8.

[0044] A method for reducing costs and increasing efficiency by improving the consumption of spotlights on a final appearance inspection table includes the following steps: Step 1: Equipment startup and preparation.

[0045] S1: Check if the power connection inside the rack 9 is normal; check if the visual inspection fixture 7 on the visual inspection table 8 is installed securely, and ensure that the spotlight 6 and heat dissipation pipes on the upper frame 1 are properly connected.

[0046] S2: Connect the internal power supply of rack 9 to power spotlight 6 and heat sink 3.

[0047] S3: Turn on the exhaust fan 11 in the radiator 3 to remove the heat generated inside the spotlight 6.

[0048] The exhaust fan 11 sends airflow into the air inlet pipe 4 through the air supply pipe 10. The airflow enters the lamp cover 15 of the spotlight 6 through the air inlet pipe 4, directly carrying away the heat generated by the light-emitting element 16. After absorbing the heat, the airflow enters the exhaust pipe 5 and flows back to the radiator or is directly discharged through the air outlet pipe 12, thereby establishing a cooling cycle before the spotlight is put into operation.

[0049] Step 2: Product testing.

[0050] S4: After the heat dissipation system is running stably, turn on the spotlight 6; the light shines on the inspection stage 8 area, providing a high-brightness inspection environment.

[0051] S5: The operator places the product to be inspected on any of the visual inspection fixtures 7 arranged in a ring on the visual inspection table 8.

[0052] S6: Start the motor of the inspection table 8 to rotate. The rotation of the inspection table 8 drives the inspection fixture 7 and the product on it to rotate. During the rotation, the product passes through the illumination area of ​​the spotlight 6 at different angles in sequence. The operator can stay still next to the workstation and clearly observe the appearance of the product from all sides without having to manually flip the product.

[0053] Step 3: Continuous monitoring and shutdown.

[0054] S7: Throughout the entire testing process, the radiator 3 continues to operate, and cold air continuously flows through the air inlet pipe 4, the lamp cover 15, and the exhaust pipe 5.

[0055] S8: After the test is completed, remove the product; repeat S5-S7 to test the next product.

[0056] S9: After the test is completed, turn off spotlight 6 first; radiator 3 continues to run for a period of time, then turn off the radiator and the power supply of the whole machine.

[0057] Working principle: Forced air cooling reduces the power consumption of the spotlight. The airflow circulation path is as follows: Air intake: When the exhaust fan 11 is running, it sends airflow into the air intake pipe 4 through the air supply pipe 10.

[0058] Cooling: Airflow enters the lamp cover 15 of the spotlight 6 and flows directly through the light-emitting element 16, carrying away the heat.

[0059] Exhaust air: The airflow that has absorbed heat enters the exhaust duct 5.

[0060] Return / Exhaust: Hot air flows back to the radiator for treatment or is directly discharged through the air outlet duct 12.

[0061] Key advantage: A cooling cycle is established before the spotlight is put into operation, ensuring that the luminaire always operates at a suitable temperature.

[0062] By employing the strict logic of "pre-cooling before lighting" and "turning off the lights before turning off the fans," the sudden brightening of the light-emitting element 16 at high temperatures or the accumulation of residual heat is avoided, which significantly slows down light decay and aging, and reduces the frequency of spotlight replacement and electricity costs.

[0063] The design employs a three-tool ring distribution combined with a rotary table, enabling continuous operation and automated multi-angle inspection. This eliminates the time wasted on manual product flipping and significantly increases daily inspection capacity.

[0064] In summary, the improved structure for spotlight consumption in the final appearance inspection table and its cost-reduction and efficiency-enhancing methods have the advantages of compact structure, soft appearance, complete functions, environmental protection and safety, integrated reading and storage, and clear handwriting.

[0065] Extending the lifespan of lighting fixtures and reducing costs is achieved by using an independent air intake and exhaust system to directly remove the heat generated by the light-emitting elements through airflow, thus avoiding high temperature accumulation.

[0066] The logic of "turning on the heat dissipation first, then turning on the light" and "turning off the light first, then turning off the heat dissipation" prevents the lamps from working without airflow for cooling or with residual heat, thus significantly reducing the aging rate of the LED beads / bulbs.

[0067] To improve testing quality and increase efficiency, an automated multi-angle inspection system was achieved by using a rotating visual inspection table in conjunction with a ring-shaped fixture, reducing the time spent manually flipping products.

[0068] Good heat dissipation ensures the stability of the spotlight's light intensity (high temperature usually leads to light decay), ensuring that the detection field of view is always clear.

[0069] Compact structure: The heat dissipation system is integrated into the top of the upper frame by using support columns as pipe supports, which saves space and ensures ventilation efficiency.

[0070] The above description is only a specific embodiment of the present invention, but the structural features of the present invention are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present invention are covered by the patent scope of the present invention.
