Description

Technical Field

[0001] This utility model relates to the technical field of circuit board testing tools, and in particular to a circuit board inspection table. Background Technology

[0002] In the circuit board manufacturing process, inspecting for copper defects inside the circuit board holes is a crucial step in ensuring circuit board quality. Currently, existing inspection methods have many inconveniences and shortcomings.

[0003] Traditional inspection methods involve a worker placing a red adhesive film on the back of the PCB board (to reduce glare from holes) in one hand and using a magnifying glass in the other to inspect for copper defects within the holes. In practice, the worker must simultaneously adhere the red adhesive film to the board surface with their hand, requiring sustained pressure to maintain this contact. Maintaining this posture for extended periods easily leads to hand fatigue, impacting inspection efficiency and accuracy. Furthermore, the lack of effective securing measures allows the red adhesive film to slip during inspection. This slippage causes visual confusion and uncertainty in the inspection location, making it difficult to accurately assess the copper content within the holes. This can result in defective PCBs being shipped out, causing serious quality problems in subsequent production and use. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a circuit board inspection table that solves the problems of worker hand fatigue, slippage of the red adhesive film leading to inconvenient inspection, and defect leakage in existing circuit board inspection methods, thereby improving the accuracy and convenience of inspecting copper defects inside circuit board holes.

By setting a first light source and a second light source, emitting red and white light respectively, suitable lighting can be provided according to different inspection needs. Furthermore, the light-transmitting plate allows the light source to pass through evenly, providing stable and uniform illumination for the circuit board, enabling workers to more clearly observe the copper condition inside the holes, thus improving inspection accuracy. Through the cooperation of the fixing components and support bars, the circuit board is stably fixed on the light-transmitting plate, avoiding the problem of the red film easily slipping when manually held, eliminating the visual confusion and uncertain detection position caused by the slipping of the red film, effectively reducing the risk of defective circuit boards leaving the site, and improving product quality.

[0023] Reference Figure 1 , Figure 2 and Figure 3This utility model proposes a circuit board inspection table, including a tabletop 100 and a support platform 200. Specifically, the support platform 200 is inclined, a design that conforms to ergonomic principles, allowing workers to maintain a more comfortable posture while inspecting circuit boards and reducing fatigue from prolonged inspections. The support platform 200 is equipped with a first light source and a second light source, used to emit red light and white light respectively. Red light reduces glare within the holes, facilitating worker observation of the copper inside; white light provides more comprehensive illumination when needed, meeting the requirements of different inspection scenarios.

[0024] Furthermore, the support platform 200 is provided with a light-transmitting plate 230, which is positioned above the first light source and the second light source. The light-transmitting plate 230 allows the light source to pass through evenly, providing stable and uniform illumination for the circuit board placed on it, ensuring that workers can clearly observe the details of the copper inside the holes of the circuit board.

[0025] It should be noted that the support platform 200 is equipped with fixing members 220, which are located on both sides of the light-transmitting plate 230. The fixing members 220 can engage with the support strip 400, which supports the bottom of the circuit board so that the circuit board can be placed on the light-transmitting plate 230. Through the cooperation of the fixing members 220 and the support strip 400, the circuit board can be stably fixed on the light-transmitting plate 230, avoiding the inconvenience of manually holding the red film and the problem of the red film slipping, thus improving the accuracy and stability of the inspection.

[0026] Understandably, the inclined design of the support platform 200 is ergonomic, allowing workers to avoid prolonged periods of discomfort while inspecting circuit boards, significantly reducing hand fatigue and improving the comfort and sustainability of the inspection process. By incorporating a first light source and a second light source, emitting red and white light respectively, suitable lighting can be provided according to different inspection needs. The light-transmitting plate 230 ensures uniform light transmission, providing stable and even illumination for the circuit boards, allowing workers to more clearly observe the copper within the holes and improving inspection accuracy. The cooperation of the fixing component 220 and the support strip 400 stably fixes the circuit board to the light-transmitting plate 230, avoiding the problem of the red film slipping when manually held, eliminating visual confusion and uncertain inspection positions caused by film slippage, effectively reducing the risk of defective circuit boards leaving the site, and improving product quality. The entire circuit board inspection table is rationally designed and has a simple structure, allowing workers to easily place circuit boards on the light-transmitting plate 230 for fixing and inspection. This convenient operation improves inspection efficiency and reduces production costs.

[0027] In some embodiments, the tabletop 100 is made of durable wood with a smooth, flat surface, providing stable support for the support platform 200. The support platform 200 is bolted to the surface of the tabletop 100 and is tilted at 30°. This tilt angle was determined through ergonomic research to allow workers to maintain a natural posture while inspecting circuit boards, reducing neck and hand fatigue. The first and second light sources are LED bulbs, installed on opposite sides inside the support platform 200. The first light source emits red light, and the second light source emits white light; both light sources can be switched on and off via a switch. The light-transmitting plate 230 is made of transparent acrylic glass, offering good light transmission and wear resistance. It is positioned above the first and second light sources, evenly distributing light onto the circuit board. The fixing members 220 are metal slots, symmetrically distributed on both sides of the light-transmitting plate 230. The support strip 400 is a long strip of plastic, with both ends capable of engaging the slots in the fixing members 220. When inspecting the circuit board, the worker first places the board on the light-transmitting plate 230, then inserts the support strip 400 into the slot of the fixing component 220, so that the support strip 400 supports the bottom of the circuit board, thus stably fixing the circuit board on the light-transmitting plate 230. The worker turns on the first light source, and the red light shines through the light-transmitting plate 230 onto the circuit board, reducing reflections inside the holes. The worker can then use a magnifying glass to clearly observe whether there are any defects in the copper inside the holes. If more comprehensive lighting is needed, the worker can turn on the second light source; the combination of white and red light further improves the observation effect.

[0028] In other embodiments, the tabletop 100 is made of metal, providing higher strength and stability. The support platform 200 has a 45° tilt angle, suitable for workers of different heights. The first and second light sources utilize fiber optic light guide plates, providing more uniform and softer light. The light-transmitting plate 230 is made of tempered glass, offering higher transparency and impact resistance. The fixing members 220 are magnetic clips located on both sides of the light-transmitting plate 230, and the support strips 400 are magnetic metal strips. When fixing the circuit board, the worker brings the support strips 400 close to the fixing members 220, and the magnetic attraction secures the support strips 400 to the fixing members 220, thereby supporting the bottom of the circuit board. This fixing method is more convenient and faster, improving inspection efficiency. During use, the worker can also turn on the first or second light source as needed, using the uniform light from the light-transmitting plate 230 to accurately inspect the copper inside the circuit board holes, avoiding problems such as the slippage of the red film in traditional inspection methods, effectively improving the quality and efficiency of circuit board inspection.

[0029] Reference Figure 1 and Figure 2Specifically, multiple fasteners 220 are evenly distributed longitudinally on both sides of the support platform 200. When inspecting circuit boards of different thicknesses or requiring different viewing heights due to special design, workers can select the appropriate fastener 220 to install the support rail 400 according to the actual situation. For example, for thinner circuit boards, the support rail 400 is installed near the bottom of the light-transmitting plate 230, placing the circuit board at a lower position; for thicker circuit boards, the support rail 400 is installed near the top of the light-transmitting plate 230, placing the circuit board at a higher position for easier observation by the worker. By setting multiple longitudinally distributed fasteners 220, the inspection needs of circuit boards of different heights can be met, improving the versatility and flexibility of the circuit board inspection platform. There is no need to design different inspection platforms specifically for circuit boards of different heights, reducing production costs and providing workers with a more convenient and comfortable inspection environment, thus improving inspection efficiency.

[0030] In some embodiments, the light-transmitting plate 230 of the support platform 200 has two rows of protrusions 221 longitudinally distributed on both sides, with multiple protrusions 221 in each row. Adjacent protrusions 221 are spaced a certain distance apart to form a fixing slot 222. The support strip 400 is a long strip that matches the size of the fixing slot 222. When placing a circuit board, the worker inserts the support strip 400 into the fixing slot 222 at a suitable height, allowing the support strip 400 to support the bottom of the circuit board. For example, when inspecting a medium-thickness circuit board, the support strip 400 is inserted into the fixing slot 222 in the middle position to ensure the circuit board is stably placed on the light-transmitting plate 230. The structure using protrusions 221 to form the fixing slot 222 is simple and stable. The support strip 400 can be easily inserted and removed, facilitating quick adjustment of the circuit board's placement height. Simultaneously, the design of two rows of protrusions 221 increases the stability of the fixing, effectively preventing the support strip 400 from shaking during inspection, ensuring the circuit board's position is fixed, and improving inspection accuracy.

[0031] In other embodiments, the light-transmitting plate 230 of the support platform 200 has two rows of fixed protrusions longitudinally distributed on both sides, with multiple fixed protrusions in each row. The support strip 400 has fixed circular grooves at both ends that match the diameter of the fixed protrusions. When placing the circuit board, the worker aligns the fixed circular grooves at both ends of the support strip 400 with the fixed protrusions of appropriate height, and then presses them firmly to engage the fixed circular grooves with the fixed protrusions, thereby securing the support strip 400 and the circuit board. For example, when inspecting a small circuit board, a lower fixed protrusion is selected for engagement. This fixing method is simple and quick, allowing workers to rapidly install and remove the support strip 400, improving inspection efficiency. The engagement structure of the fixed protrusions and fixed circular grooves is robust and reliable, capable of withstanding a certain amount of external force, ensuring that the support strip 400 will not loosen during inspection, guaranteeing stable placement of the circuit board, and facilitating accurate observation of the copper inside the holes.

[0032] Reference Figure 3 The tabletop 100 is rotatably connected to an adjusting rod 110 via a pivot. The bottom of the support platform 200 has multiple support platform steps of varying heights. When the tilt angle of the support platform 200 needs adjustment, the worker rotates the adjusting rod 110, positioning it against different support platform steps. For example, initially, the adjusting rod 110 is against the lowest support platform step, resulting in a smaller tilt angle. When a larger tilt angle is needed for more comfortable observation of the circuit board, the worker rotates the adjusting rod 110, positioning it against a higher support platform step, increasing the tilt angle. Through the coordination of the adjusting rod 110 and the support platform steps, the tilt angle of the support platform 200 can be easily adjusted to meet the operating habits and inspection needs of different workers. Workers can adjust the support platform 200 to the most suitable tilt angle based on their height, posture, and other factors, reducing fatigue from prolonged inspections and improving the comfort and efficiency of the inspection work.

[0033] Reference Figure 1 and Figure 2 In some embodiments, a rectangular mounting slot 201 is formed inside the support platform 200, and the first and second light sources are installed in the mounting slot 201. A power supply and controller are also installed within the mounting slot 201. The power supply provides power to the light sources, and the controller controls the switching and brightness adjustment of the light sources. A light-transmitting plate 230 is fixed to the opening of the mounting slot 201 with screws, enclosing the light sources inside while allowing light to pass through and illuminate the circuit board. Workers can turn the light sources on or off using the controller and adjust their brightness as needed. Integrating the light source, power supply, and controller within the mounting slot 201 makes the entire circuit board inspection table more compact and streamlined. The light-transmitting plate 230, by sealing the opening of the mounting slot 201, protects the internal light sources and electrical components from dust and debris, while ensuring uniform light transmission and providing stable illumination for the circuit board. Furthermore, centralized control of the light source's switching and brightness facilitates worker operation and improves inspection efficiency.

[0034] Furthermore, a wiring hole is provided on the side of the mounting slot 201, through which the wire connecting the control button 300 is passed, connecting it to the power supply and the controller respectively. The control button 300 is located on the side of the support platform 200 for easy operation by the worker. When the worker needs to turn on the first light source, pressing the corresponding control button 300 transmits current through the wire to the controller, which then controls the first light source to illuminate; similarly, pressing the button controlling the second light source turns on the white light. Alternatively, a master switch button can be provided to control both light sources simultaneously. By providing the wiring hole and control button 300, the control part of the light source is extended from inside the mounting slot 201 to a position easily accessible to the worker, allowing them to conveniently control the light source without complex operations inside the mounting slot 201. This design improves operational convenience and safety, reduces the risk of electric shock that may occur when operating inside the mounting slot 201, and also improves the efficiency of inspection work.

[0035] Reference Figure 1 and Figure 2 Within the mounting slot 201, multiple red light tubes 210 are installed as the primary light source, and multiple white light tubes 210 as the secondary light source. The tubes 210 are arranged equidistantly and evenly side-by-side to ensure uniform light illumination onto the light-transmitting plate 230. When the light source is turned on, the multiple tubes 210 emit light simultaneously, providing ample and uniform illumination, allowing workers to clearly observe the details of the copper within the circuit board holes. For example, when inspecting a circuit board with a complex circuit, uniform light helps workers accurately detect minute defects in the copper within the holes. Using multiple equidistant and evenly arranged tubes 210 as the light source provides more uniform and brighter light, avoiding the lighting blind spots and uneven light that can occur with a single light source. Uniform light helps workers more accurately observe the copper within the circuit board holes, improving the accuracy and reliability of the inspection and reducing missed or false detections due to lighting issues.

[0036] Reference Figure 1 It should be noted that a rubber foot 120 is installed at each of the four corners of the bottom of the tabletop 100. The rubber feet 120 have a certain degree of elasticity and anti-slip properties, ensuring the circuit board inspection table is stably placed on the ground while reducing the impact of vibration on the inspection work. A drawer 130 is installed under the tabletop 100, connected to the tabletop 100 via a sliding rail for easy pulling out. The drawer 130 can hold tools needed for inspecting circuit boards, such as a magnifying glass, tweezers, a recording pen, and a notebook.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
