Description

Technical Field

[0001] This utility model relates to the field of vehicle production and testing technology, and in particular to a mobile testing light. Background Technology

[0002] In vehicle manufacturing, various curved workpieces are frequently encountered, such as curved components in car doors and curved covers in engine compartments. The appearance quality of these curved workpieces has a crucial impact on the overall aesthetics, assembly precision, and final product quality of the vehicle. Currently, the appearance inspection of curved workpieces includes instrument inspection and visual inspection. Visual inspection requires illuminating the surface of the curved workpiece with an inspection lamp. Existing inspection lamps are usually fixed light sources, requiring the curved workpiece to be moved close to the lamp for inspection, resulting in low inspection efficiency. Furthermore, because the inspection lamp is a point light source, the distance between the lamp and various positions on the curved workpiece is inconsistent, leading to poor illumination uniformity and unsatisfactory surface inspection results for curved workpieces. Utility Model Content

[0003] The main purpose of this invention is to propose a mobile inspection lamp, which aims to solve the technical problems of low inspection efficiency and poor inspection effect when performing appearance inspection on curved workpieces of vehicles in the prior art.

[0004] To achieve the above objectives, this utility model proposes a mobile inspection lamp for inspecting curved workpieces on vehicles. The mobile inspection lamp includes a base, an arc-shaped plate, and a lamp assembly. Wheels are mounted below the base. The arc-shaped plate is an adjustable-curvature plastic plate, mounted on the base and extending upwards. Multiple mounting positions are formed on the inner arc surface of the arc-shaped plate, each extending axially along the plate. These mounting positions are spaced apart from the bottom to the top of the arc-shaped plate. The lamp assembly includes a cable and multiple light strips. Each mounting position has a corresponding light strip installed. The extension direction of each light strip is consistent with the extension direction of its corresponding mounting position, and each light strip faces the curved workpiece. The multiple light strips are connected in series via the cable to an external power source, and a switch is provided on the cable.

[0005] In one embodiment, the inner arc surface of the arc plate protrudes inward to form a plurality of bosses, the plurality of bosses are spaced apart from the bottom to the top of the arc plate, the top surface of each boss forms the mounting position, and a groove is formed between any two adjacent bosses.

[0006] In one embodiment, the top surface of the boss is provided with a mounting groove, the light strip is snapped, threaded, or glued into the mounting groove, and the connection between the mounting groove and the light strip is filled with sealant.

[0007] In one embodiment, the outer arc surface of the arc plate is provided with a plurality of first reinforcing ribs spaced apart from the bottom to the top of the arc plate and a plurality of second reinforcing ribs spaced apart along the axial direction of the arc plate. Each first reinforcing rib extends along the axial direction of the arc plate, and each second reinforcing rib extends along the direction from the bottom to the top of the arc plate. The plurality of first reinforcing ribs and the plurality of second reinforcing ribs are arranged intersectingly.

[0008] In one embodiment, the first reinforcing rib near the base is a support rib, and a plurality of support rods are connected between the support rib and the base. The plurality of support rods are distributed at intervals along the axial direction of the arc-shaped plate, and each support rod is inclined.

[0009] In one embodiment, a first counterweight and a second counterweight are respectively installed on the base at the inner and outer sides of the arc-shaped plate, with the first counterweight installed below the base and the second counterweight installed above the base.

[0010] In one embodiment, the light strip is an LED light strip, and the LED light strip is provided with a plurality of LED beads, which are evenly distributed on the light strip at intervals along the extension direction of the light strip.

[0011] In one embodiment, the outer arc surface of the arc-shaped plate is provided with a cable reel for receiving the cable.

[0012] In one embodiment, the traveling wheel is a swivel wheel, and the traveling wheel is equipped with a braking device.

[0013] In one embodiment, the arc-shaped plate is provided with two handrails on each side along its axial direction.

[0014] This invention proposes a mobile inspection lamp that uses multiple light strips arranged on the inner arc surface of an arc-shaped plate. When the arc-shaped plate approaches the arc-shaped workpiece to be inspected, the multiple light strips illuminate the surface of the workpiece, facilitating visual inspection. The arc-shaped plate is mounted on a movable base, allowing the base to move the plate to the side of the workpiece's adjustment equipment. The multiple light strips on the arc-shaped plate then perform visual inspection, enabling simultaneous adjustment and visual inspection of the workpiece. This significantly improves the flexibility of the mobile inspection lamp and thus increases the efficiency of visual inspection of arc-shaped workpieces. The arc-shaped plate is made of a plastic material, such as stainless steel or aluminum, giving it plasticity and allowing it to change its curvature under external force to adapt to workpieces of varying curvatures. This ensures that the curvature of the arc-shaped plate matches that of the workpiece, allowing the multiple light strips to evenly illuminate the workpiece surface, guaranteeing uniform illumination and improving surface inspection results.

If the specific posture changes, the directional indicators will also change accordingly.

[0025] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0026] In this utility model, the descriptions of directions such as "up", "down", "front", "back", "left", and "right" are as follows: Figure 1 and Figure 2 The directions shown are for reference only and are used to interpret the location. Figure 1 and Figure 2 The relative positional relationship between the components in the shown posture is such that if the specific posture changes, the directional indication will also change accordingly.

[0027] Currently, the appearance inspection of curved workpieces includes instrument inspection and visual inspection. When performing visual inspection, it is necessary to use an inspection lamp to illuminate the surface of the curved workpiece. Existing inspection lamps are usually fixed light sources, which require moving the curved workpiece closer to the inspection lamp for inspection. This results in low inspection efficiency. Furthermore, since the inspection lamp is a point light source, the distance between the inspection lamp and various positions on the curved workpiece is inconsistent, leading to poor illumination uniformity and unsatisfactory surface inspection results for the curved workpiece.

[0028] This utility model proposes a mobile inspection lamp for inspecting curved workpieces on vehicles. The mobile inspection lamp includes a base 10, an arc plate 20, and a lamp assembly 30. Wheels 11 are mounted below the base 10. The arc plate 20 is an adjustable-curvature plastic plate, mounted on the base 10 and extending upwards. Multiple mounting positions are formed on the inner arc surface 21 of the arc plate 20, each extending axially along the arc plate 20. These mounting positions are spaced apart from the bottom to the top of the arc plate 20. The lamp assembly 30 includes a cable and multiple light strips 31. Each mounting position has a corresponding light strip 31, and the extension direction of each light strip 31 is consistent with the extension direction of its corresponding mounting position. Each light strip 31 faces the curved workpiece. The multiple light strips 31 are connected in series via a cable to an external power source, and a switch is installed on the cable.

[0029] Please see Figure 1 and Figure 2 , Figure 1 and Figure 2 The left-right direction is the axial direction of the arc plate 20. The arc plate 20 is set on the base 10. Multiple light strips 31 are provided on the inner arc surface 21 of the arc plate 20. When the base 10 moves via the traveling wheels 11, it drives the arc plate 20 to move, allowing the arc plate 20 to approach the arc-shaped workpiece of the vehicle. The multiple light strips 31 illuminate the surface of the arc-shaped workpiece for visual inspection. The arc plate 20 is a plastic plate that can be bent under external force to change its curvature, making the curvature of the arc plate 20 consistent with the curvature of the arc-shaped workpiece to be inspected. This allows the arc plate 20 to better fit the surface of the arc-shaped workpiece, thus adapting to arc-shaped workpieces with different curvatures. The multiple light strips 31 are connected in series by a cable with a switch connected in series on the cable. The switch controls the on / off state of the cable, thereby controlling the opening and closing of each light strip 31. This facilitates centralized control of multiple light strips 31. The switch uses existing technology. It can be noted that the mobile detection lamp proposed in this utility model can be equipped with multiple arc plates 20, and the multiple arc plates 20 are spliced ​​together along the axial direction of each arc plate 20, so as to adapt to arc workpieces of different lengths.

[0030] The mobile inspection lamp proposed in this utility model uses multiple light strips 31 arranged on the inner arc surface 21 of the arc plate 20. When the arc plate 20 is close to the arc-shaped workpiece to be inspected, the multiple light strips 31 illuminate the surface of the arc-shaped workpiece to facilitate visual inspection of the workpiece surface. The arc plate 20 is mounted on a movable base 10, allowing the base 10 to move the arc plate 20. The arc plate 20 can be moved to the side of the adjustment equipment for the arc-shaped workpiece, and the multiple light strips 31 on the arc plate 20 perform visual inspection of the arc-shaped workpiece. This allows the adjustment and visual inspection of the arc-shaped workpiece to be performed simultaneously, effectively improving the flexibility of the mobile inspection lamp and thus increasing the efficiency of visual inspection of arc-shaped workpieces. The curved plate 20 is made of plastic plate, such as stainless steel plate or aluminum plate in the existing technology, so that the curved plate 20 itself has plasticity and can change its curvature under the action of external force to adapt to curved workpieces with different curvatures. This ensures that the curvature of the curved plate 20 is consistent with that of the curved workpiece, so that multiple light strips 31 can evenly illuminate the surface of the curved workpiece, ensuring the uniformity of illumination and thus improving the surface inspection effect.

[0031] In one embodiment, the inner arc surface 21 of the arc plate 20 protrudes inward to form a plurality of bosses 211. The plurality of bosses 211 are spaced apart from the bottom to the top of the arc plate 20. The top surface of each boss 211 forms a mounting position, and a groove 212 is formed between any two adjacent bosses 211.

[0032] Please see Figure 3 and Figure 4Each boss 211 protrudes inward from the inner arc surface 21 of the arc plate 20. The platform of the boss 211 forms a mounting position for mounting the light strip 31, so that the light strip 31 protrudes inward. When the arc plate 20 is close to the arc-shaped workpiece, the light strip 31 can get closer to the surface of the arc-shaped workpiece, thereby improving the surface inspection effect. Two adjacent bosses 211 form a groove 212, which extends along the axial direction of the arc plate 20. When the arc of the arc plate 20 is adjusted, the distance between two adjacent bosses 211 also changes. The groove 212 can prevent two adjacent bosses 211 from colliding, thereby preventing two adjacent light strips 31 from interfering with each other.

[0033] In one embodiment, the top surface of the boss 211 is provided with a mounting groove, and the light strip 31 is snapped, threaded, or glued into the mounting groove, and the connection between the mounting groove and the light strip 31 is filled with sealant.

[0034] It can be explained that each boss 211 has a mounting groove on its top surface. The shape of the mounting groove is adapted to the bottom of the light strip 31. The light strip 31 is fixed in the mounting groove by snap-fit, threaded connection, or adhesive bonding. The snap-fit ​​method uses elastic buckles on both sides of the mounting groove. When the light strip 31 is inserted, the buckles deform and automatically reset to lock the light strip 31 in place. The threaded connection uses a nut pre-embedded in the bottom of the mounting groove, and the bottom of the light strip 31 has a threaded hole, which is tightened with screws for fixation. The adhesive method uses high-temperature resistant silicone rubber adhesive to stick the light strip 31 into the mounting groove. The connection between the mounting groove and the light strip 31 is filled with sealant using a special glue injection device. After the sealant cures, it forms a sealing layer, ensuring a tight connection between the light strip 31 and the mounting groove. This prevents external environmental contaminants from entering the arc plate 20, ensuring the reliability and detection accuracy of the detection lamp under complex working conditions.

[0035] In one embodiment, the outer arc surface 22 of the arc plate 20 is provided with a plurality of first reinforcing ribs 221 spaced apart from the bottom to the top surface of the arc plate 20 and a plurality of second reinforcing ribs 222 spaced apart along the axial direction of the arc plate 20. Each first reinforcing rib 221 extends along the axial direction of the arc plate 20, and each second reinforcing rib 222 extends along the direction from the bottom to the top of the arc plate 20. The plurality of first reinforcing ribs 221 and the plurality of second reinforcing ribs 222 are arranged intersectingly.

[0036] Please see Figure 2 The first reinforcing rib 221 and the second reinforcing rib 222 are both provided on the outer arc surface 22 of the arc plate 20. The first reinforcing rib 221 extends along the axial direction of the arc plate 20, and the second reinforcing rib 222 extends along the direction from the bottom to the top of the arc plate 20. The first reinforcing rib 221 and the second reinforcing rib 222 intersect each other to form a mesh support structure, which together support the outer arc surface 22 of the arc plate 20, effectively improving the structural strength and overall rigidity of the arc plate 20, and ensuring that the arc plate 20 provides stable support for the lighting assembly 30.

[0037] In one embodiment, the first reinforcing rib 221 near the base 10 is a support rib, and a plurality of support rods 223 are connected between the support rib and the base 10. The plurality of support rods 223 are distributed at intervals along the axial direction of the arc plate 20, and each support rod 223 is inclined.

[0038] Please continue reading. Figure 2 The first reinforcing rib 221 at the bottom of the arc plate 20 is a support rib. A support rod 223 is connected between the edge of the base 10 and the support rib. The support rod 223, the base 10 and the arc plate 20 together form a triangular support structure, which further improves the support stability of the arc plate 20 and ensures that the arc plate 20 can provide stable support for the lighting assembly 30.

[0039] In one embodiment, a first counterweight 224 and a second counterweight 225 are respectively installed on the base 10 at the inner and outer sides of the arc plate 20. The first counterweight 224 is installed below the base 10, and the second counterweight 225 is installed above the base 10.

[0040] It should be noted that the curved plate 20 is bent inwards, and the first counterweight 224 located on the inner side of the curved plate 20 is installed below the base 10, while the second counterweight 225 located on the outer side of the curved plate 20 is installed above the base 10. This effectively lowers the center of gravity of the entire mobile inspection lamp and brings the center of gravity of the mobile inspection lamp closer to the middle of the base 10, thereby improving the stability of the mobile inspection lamp, effectively preventing the base 10 from tipping over and sliding, and ensuring the reliability of the mobile inspection lamp during the inspection process.

[0041] In one embodiment, the light strip 31 is an LED light strip 31, and a plurality of LED beads are disposed on the LED light strip 31. The plurality of LED beads are evenly distributed on the light strip 31 at intervals along the extension direction of the light strip 31.

[0042] Understandably, multiple LED beads are evenly distributed along the extension direction of the light strip 31, ensuring that the light generated by the LED light strip 31 can uniformly illuminate the surface of the curved workpiece, providing good lighting conditions for inspection and avoiding areas with excessively strong or weak light, thereby improving the accuracy and reliability of the inspection. The LED beads used are those from existing technologies.

[0043] In one embodiment, the outer arc surface 22 of the arc plate 20 is provided with a cable reel 226 for storing cables.

[0044] Understandably, by setting up the cable reel 226, the cable can be neatly stored inside, avoiding unnecessary friction and collisions with external objects during movement, thereby extending the cable's service life. Simultaneously, the length of the cable extending out of the cable reel 226 can be flexibly adjusted according to actual testing needs. When a longer cable is required, the appropriate length can be pulled out of the cable reel 226; after testing, the cable can be neatly retracted into the cable reel 226, maintaining the equipment's cleanliness and order.

[0045] In one embodiment, the traveling wheel 11 is a swivel wheel, and a braking device is provided on the traveling wheel 11.

[0046] Understandably, the casters can move the lamp assembly 30 to the inspection position via the base 10, allowing the inspection lamp to flexibly change direction during movement. This facilitates quick adjustment of the inspection lamp's position by the operator according to actual inspection needs. The braking device securely locks the casters, preventing the inspection lamp from moving due to accidental contact or uneven ground during inspection, thereby improving the reliability and repeatability of the inspection. It should be noted that the braking device uses existing technology that can cooperate with the casters, which will not be elaborated further here.

[0047] In one embodiment, the arc-shaped plate 20 is provided with two handrails 227 on each side along its axial direction.

[0048] Please see Figure 2 Two handrails 227 are respectively set on the left and right sides of the arc-shaped plate 20. When moving the detection light, the operator can easily push or pull the detection light by holding the handrails 227, making the movement process more stable and effortless. The handrails 227 not only improve the convenience of operation, but also increase the safety of operation, preventing the operator from having an accident due to contact with other parts of the detection light during the movement.

[0049] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
