Description

Technical Field

[0001] This application relates to the field of visual inspection, and in particular to a visual inspection platform for small industrial products. Background Technology

[0002] In industrial production, efficient and accurate visual inspection of small industrial products (such as electronic components, precision parts, connectors, and small assemblies) is a key step in ensuring product quality. Dedicated inspection platforms or workbenches provide a standardized operating environment for such inspections, typically including a table for placing the product under test and necessary auxiliary systems, among which lighting systems are particularly important.

[0003] Traditional visual inspection platforms typically employ top direct lighting. Specifically, the light source (such as LED strips or bulbs) is usually mounted directly above the inspection table or above the operator via a fixed bracket or adjustable cantilever. This design aims to provide basic brightness to the entire table surface.

[0004] However, top lighting with a single light source has the following drawbacks: When operators approach the testing table and bend over to perform fine operations (such as observing subtle product features, checking surface defects, reading minute scales or markings, or performing manual adjustments), their head, shoulders, or upper body will naturally be positioned between the light source and the product under test. This results in the operator's own projection (shadow) forming in the key observation area of ​​the product under test (especially in the area directly in front of or below the operator). The light intensity in these shadowed areas is significantly reduced, forming local dark areas that may obscure the product's detailed features. Operators also need to frequently move their head and body or adjust the product angle to avoid the shadow or find a suitable light angle, thus affecting the overall efficiency and accuracy of visual inspection. Utility Model Content

[0005] To improve the problem of shadow occlusion caused by a single light source, this application provides a small-scale industrial product visual inspection platform.

[0006] The technical solution adopted in this application for a small-scale industrial product visual inspection platform is as follows: A small-scale industrial product visual inspection platform, comprising: The testing table includes a tabletop and a support fixedly mounted on the tabletop; A fixed lighting mechanism, fixedly mounted on the bracket, includes a first lighting lamp whose lighting direction faces the table surface; The movable lighting mechanism, located below the fixed lighting mechanism, includes a second light fixture movably mounted on the bracket, and also includes a telescopic adjustment component and a rotation adjustment component. The telescopic adjustment component is used to adjust the distance between the second light fixture and the operator in the horizontal direction, and the rotation adjustment component is used to adjust the lighting direction of the second light fixture.

[0007] The fixed lighting mechanism provides basic ambient light; the operator adjusts the position of the second light lamp by telescopic adjustment components and changes the illumination angle of the second light lamp by rotating adjustment components. The two work together to project the light source directly and accurately onto the key observation area directly in front of the operator, forming effective lateral supplementary lighting, which helps to reduce shadows and thus improve the clarity, accuracy and efficiency of visual inspection.

[0008] Furthermore, the bracket includes several vertical support rods, and also includes an upper support and a lower support plate fixedly connected to the support rods. The upper support and the lower support plate are both horizontally arranged. The first lighting lamp is fixedly arranged on one side of the upper support, and the second lighting lamp is movably arranged on one side of the lower support plate.

[0009] The upper support and lower support plate provide independent, stable, and hierarchically distinct mounting foundations for the fixed and movable lighting mechanisms. This structure effectively separates the two lighting systems in space, avoiding mutual interference between the mechanisms and making the lighting layout more rational. The first lighting lamp is installed high on the upper support to ensure broad ambient light coverage; the second lighting lamp is installed low on the lower support plate, creating the necessary conditions for providing illumination from below and the sides and reducing shadows.

[0010] Furthermore, both the first and second lights are elongated and horizontally positioned, and the rotation axis of the second light is also horizontally positioned.

[0011] Using a long, horizontally oriented light source creates a uniform and wide strip of light, which effectively reduces glare and strong light-shadow contrast compared to point light sources. Setting the rotation axis of the second light source horizontally also allows the light to be "sweeped" to different positions on the table, making it easy to operate and highly directional.

[0012] Furthermore, a fixed seat is fixedly connected to the lower end face of the lower support plate, and the telescopic adjustment assembly includes a slide rod that slides through the fixed seat. The slide rod is horizontally arranged and its axis points towards the operator. A mounting base is fixedly connected to one end of the slide rod, and a connecting frame is rotatably connected to the mounting base. The second lighting lamp is fixedly mounted on the connecting frame.

[0013] The horizontal sliding of the slider enables linear stepless adjustment of the distance between the light and the operator, meeting the needs of different operating scenarios; the illumination angle of the second light can be adjusted by rotating the connecting bracket.

[0014] Furthermore, the bottom of the fixed base is threaded with a threaded knob, the threaded knob includes a screw and a knob fixed to one end of the screw, the screw is threaded through the fixed base, and the end of the screw away from the knob abuts against the side wall of the slide rod.

[0015] Locking is achieved by tightening the knob, which utilizes the end of the screw to directly abut against and increase the friction between it and the slide rod, eliminating the need for a complex clamping mechanism. This method is convenient to adjust, provides sufficient and stable locking force, and ensures that the second light will not shift due to accidental contact after being adjusted to the correct position, thus guaranteeing the stability of the lighting status.

[0016] Furthermore, a protrusion is fixed to the end of the slide rod away from the mounting base.

[0017] The protrusions limit the movement and prevent the operator from pulling the slide bar out of the fixed seat, thus avoiding the risk of the lighting mechanism falling off.

[0018] Furthermore, the rotation adjustment assembly includes threaded shafts fixed to both ends of the connecting bracket. The axial direction of the threaded shafts is horizontal. Both ends of the mounting base are provided with through holes for the corresponding threaded shafts to pass through. Locking elements are provided on the threaded shafts for locking the threaded shafts.

[0019] Rotating the connecting bracket around the threaded shaft allows for adjustment of the angle of the second lighting lamp; the locking mechanism secures the lamp after rotational adjustment.

[0020] Furthermore, the locking element includes a threaded swivel ring threaded to the threaded shaft; when the threaded swivel ring is tightened to the threaded shaft, one side of the threaded swivel ring abuts against the mounting base.

[0021] Tighten the threaded swivel so that its end face fits tightly against the side wall of the mounting base, and prevent the threaded shaft (and connecting bracket) from rotating by friction; this locking method has high torque, good self-locking performance, and convenient operation for loosening and locking.

[0022] Furthermore, both the knob and the threaded ring have anti-slip structures on their outer periphery.

[0023] Anti-slip structures (such as knurling, texture, grooves, etc.) help increase the friction between the hand and the knob or threaded ring, thereby improving the ease of operation.

[0024] Furthermore, the fixed lighting mechanism is provided in one or more sets, and the movable lighting mechanism is provided in one or more sets, with the number of fixed lighting mechanisms and movable lighting mechanisms being the same and their positions corresponding one-to-one.

[0025] Setting up multiple workstations on the testing platform, with each workstation corresponding to a set of fixed lighting mechanisms and movable lighting mechanisms, helps to improve the applicability of the testing platform.

[0026] In summary, this application includes the following beneficial technical effects: This application adds a movable lighting mechanism (second lighting lamp) with horizontal telescopic adjustment and lighting direction rotation adjustment functions. This allows the light source to be moved directly and flexibly and aligned with the work area directly in front of the operator, which is equivalent to providing supplementary lighting from the side of the observation angle. This improves the problem of shadows caused by the operator's body blocking the top light source (first lighting lamp) and helps to improve the clarity and accuracy of visual inspection.

[0029] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0030] This application discloses a small-scale visual inspection platform for industrial products. (Refer to...) Figure 1 The small industrial product visual inspection platform includes an inspection table 1, a fixed lighting mechanism 2, a movable lighting mechanism 3, and a collection mechanism 4. In this embodiment, the inspection table 1 is provided with four inspection stations, and each inspection station is provided with a set of fixed lighting mechanisms 2 and a set of movable lighting mechanisms 3.

[0031] Reference Figure 1 and Figure 2 The testing table 1 includes a table surface 11 and a support 12 fixedly installed on the table surface 11. The support 12 includes several vertical support rods 121, and also includes an upper support 122 and a lower support plate 123 fixedly connected to the support rods 121. The upper support 122 and the lower support plate 123 are both horizontally arranged.

[0032] Reference Figure 1 and Figure 2 The fixed lighting mechanism 2 is fixedly installed on one side of the support 122 on the bracket 12, and includes a first light 21 with the lighting direction facing the table surface 11. The first light 21 is elongated and horizontally positioned, and is mounted on the upper support 122 by a cantilevered mounting bracket. The position of the first light 21 is usually above the operator's head, and the lighting direction is fixed downwards to provide basic ambient light.

[0033] Reference Figure 1 and Figure 2 The movable lighting mechanism 3 is located below the fixed lighting mechanism 2 and includes a second light 31 movably mounted on one side of the lower support plate 123 of the bracket 12. The second light 31 is elongated and horizontally positioned. The lengths of both the first light 21 and the second light 31 are greater than the width of the product being inspected and also greater than the width of the operator's body. The position of the second light 31 is typically below the operator's head. The movable lighting mechanism 3 also includes a telescopic adjustment component and a rotation adjustment component. The telescopic adjustment component is used to adjust the distance between the second light 31 and the operator in the horizontal direction, and the rotation adjustment component is used to adjust the lighting direction of the second light 31.

[0034] The operator adjusts the position of the second illumination lamp 31 by extending and retracting the adjustment component, and changes the illumination angle of the second illumination lamp 31 by rotating the adjustment component. The two work together to project the light source directly and accurately onto the key observation area in front of the operator, forming effective lateral supplementary lighting, which helps to reduce shadows and thus improve the clarity, accuracy and efficiency of visual inspection.

[0035] To achieve the adjustment of the position of the second lighting lamp 31, refer to Figure 3 and Figure 4 At each testing station, two fixed seats 32 are fixedly connected to the lower end face of the lower support plate 123. The telescopic adjustment assembly includes a sliding rod 33 that slides through the fixed seat 32. The sliding rod 33 is horizontally set and its axis points towards the operator. The ends of the two sliding rods 33 are fixedly connected to a mounting base 331. A connecting frame 34 is rotatably connected to the mounting base 331. The second lighting lamp 31 is fixedly mounted on the connecting frame 34.

[0036] Reference Figure 4The bottom of the fixed base 32 is threadedly connected to a threaded knob 321. The threaded knob 321 includes a screw and a knob fixed to one end of the screw. The screw thread passes through the fixed base 32, and the axis of the screw is orthogonal to the axis of the slide rod 33. When the threaded knob 321 is tightened, the end of its screw away from the knob abuts against the side wall of the slide rod 33, thereby locking the slide rod 33. To facilitate the operator in turning the knob, anti-slip protrusions are provided on the outer periphery of the knob.

[0037] Loosen the threaded knobs 321 on the two fixed seats 32 to release the position lock of the slide rod 33. The operator can then adjust the horizontal position of the second light lamp 31 by pushing or pulling the mounting base 331 to slide the slide rod 33 along the corresponding fixed seat 32. After adjustment, tighten the threaded knobs 321 to lock the position of the second light lamp 31. To prevent the connecting bracket 34 from falling off the fixed seat 32 during the pushing and pulling process, refer to... Figure 4 A protrusion 332 is fixedly connected to the end of the slide rod 33 away from the mounting base 331.

[0038] To achieve the adjustment of the illumination angle of the second lighting lamp 31, refer to Figure 4 The connecting frame 34 includes a rotating seat (not shown) and a mounting plate fixed to the rotating seat. The second lighting lamp 31 is fixed to the mounting plate. The rotating seat is cylindrical, and the rotation adjustment assembly includes threaded shafts 341 coaxially fixed to both ends of the rotating seat. The axial direction of the threaded shafts 341 is horizontal. The mounting seat 331 is U-shaped and has a certain degree of elasticity. It can be made of plastic. Both ends of the mounting seat 331 are provided with through holes for the corresponding threaded shafts 341 to pass through, so that the connecting frame 34 is rotatably mounted on the mounting seat 331, and the rotation axis of the second lighting lamp 31 is also horizontal. A locking element is provided on the threaded shaft 341 for locking the threaded shaft 341.

[0039] Specifically, refer to Figure 4 The end of the rotating seat of the connecting frame 34 abuts against the inner side of the mounting base 331. The locking element includes a threaded ring 342 threadedly connected to the end of the threaded shaft 341. When the threaded ring 342 is tightened onto the threaded shaft 341, one side of the threaded ring 342 abuts against the outer side of the mounting base 331, causing the inner side of the mounting base 331 to abut against the end of the rotating seat of the connecting frame 34. The connecting frame 34 is locked by the friction between the inner side of the mounting base 331 and the end of the rotating seat of the connecting frame 34. To facilitate the operator in turning the threaded ring 342, anti-slip protrusions are provided on the outer circumference of the threaded ring 342.

[0040] Loosen the threaded swivel rings 342 at both ends of the mounting base 331 to release the lock of the connecting bracket 34. Rotate the connecting bracket 34 around the threaded shaft 341 to adjust the lighting angle of the second light lamp 31. After adjustment, tighten the threaded swivel rings 342 to fix the connecting bracket 34 on the mounting base 331, thereby fixing the lighting angle of the second light lamp 31.

[0041] Reference Figure 1 The collection mechanism 4 is located on both sides of the testing platform 1. (Refer to...) Figure 5 A fixing plate 42 is fixedly connected to the side of the tabletop 11. A horizontal slide rail 43 is fixedly connected to the fixing plate 42, and a slide block 44 is slidably mounted on the slide rail 43. The collection mechanism 4 includes a collection box 41, which can be used to collect debris or store testing tools. The collection box 41 and the slide block 44 are fixedly connected by a connecting plate 45. By pulling the collection box 41 along the length of the slide rail 43, the slide block 44 is disengaged from the slide rail 43, and the collection box 41 can be disassembled.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
