Description

Technical Field

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

[0002] Vehicle body panels, trim pieces, and structural components involve a large number of sheet metal parts. The appearance quality of these parts directly affects the overall aesthetics and safety of the vehicle. Therefore, visual inspection of these sheet metal parts is a crucial task during vehicle production. Currently, the visual inspection of vehicle sheet metal parts mainly relies on visual observation by inspectors using inspection lights. Existing inspection lights are usually fixed in place, requiring them to be moved to different locations when inspecting sheet metal parts of different shapes and positions. This lack of flexibility significantly limits the efficiency of the visual inspection work. Furthermore, existing inspection lights typically use a point light source design, resulting in overly concentrated light that causes some areas of the sheet metal to be too bright while other areas remain too dark, failing to clearly display the details of the sheet metal surface and leading to poor visual inspection results. Utility Model Content

[0003] The main purpose of this invention is to propose a mobile appearance inspection light, which aims to solve the technical problems of insufficient flexibility and poor inspection effect of the inspection lights for vehicle parts in the prior art.

[0004] To achieve the above objectives, the present invention proposes a mobile appearance inspection lamp comprising a bracket, a lamp housing, and a light-transmitting plate. The bracket includes two vertically arranged vertical rods, the bottom of each vertical rod being connected to a base. A traveling wheel is installed at the bottom of the base. Two connecting rods are connected between the two vertical rods at vertical intervals. The connecting rods are arranged horizontally, and the two vertical rods and the two connecting rods together enclose an installation space. The lamp housing is installed within the installation space, forming a receiving cavity. Multiple lamp tubes are installed within the receiving cavity, and the multiple lamp tubes are arranged at horizontal intervals. Each lamp tube extends vertically. At least one side of the lamp housing along the longitudinal direction has a light-transmitting opening communicating with the receiving cavity. The light-transmitting plate covers the light-transmitting opening, and the side of the light-transmitting plate forms an inspection side for inspecting vehicle parts. The light-transmitting plate is provided with multiple light-shielding strips at intervals, and a light-transmitting gap is formed between any two adjacent light-shielding strips.

[0005] In one embodiment, the lamp housing has two light-transmitting openings on opposite sides along the longitudinal direction, and two light-transmitting plates are respectively covered at the two light-transmitting openings to form two detection sides. On one of the light-transmitting plates, a plurality of light-shielding strips are arranged at intervals along the lateral direction and each light-shielding strip extends vertically. On the other light-transmitting plate, a plurality of light-shielding strips are arranged at intervals along the vertical direction and each light-shielding strip extends horizontally.

[0006] In one embodiment, the edge of each of the light-transmitting plates is bonded to the edge of the light-transmitting opening provided on the same side thereon, and a sealing strip is provided at the bonding point between the light-transmitting plate and the lamp housing.

[0007] In one embodiment, the lamp housing has heat dissipation holes communicating with the receiving cavity on both sides along the lateral direction.

[0008] In one embodiment, a plurality of the lamps are connected in series by a cable, and a cable reel is mounted on one of the vertical poles to accommodate the cable.

[0009] In one embodiment, a control cabinet is mounted on one of the vertical poles, and the control cabinet is electrically connected to each of the lamps via the cable.

[0010] In one embodiment, a diagonal strut connects each of the bases and the vertical rods attached thereto.

[0011] In one embodiment, a counterweight is installed at the bottom of the base.

[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 lamp tube is an LED lamp tube, and a plurality of LED beads are disposed on the lamp tube. The plurality of LED beads are evenly distributed at intervals along the extension direction of the LED lamp tube, and the light-transmitting plate is a glass plate.

[0014] This utility model proposes a mobile appearance inspection lamp. Two vertical rods and two connecting rods provide stable support for the lamp housing. The two vertical rods are respectively connected to two bases, each equipped with wheels. The lamp housing can be moved via a bracket, allowing the lamp to be positioned to illuminate the appearance of vehicle panels for inspection, effectively improving its flexibility. Multiple lamp tubes are arranged horizontally at intervals within the lamp housing. Multiple horizontally spaced light-shielding strips are provided on the light-transmitting plate, with each strip corresponding to one of the lamp tubes. A light-transmitting gap is formed between any two adjacent light-shielding strips, allowing the inspection light emitted from the lamp tubes to shine onto the vehicle panels through this gap. When the inspection light from multiple lamp tubes exits through the same light-transmitting gap, interference occurs, forming alternating light and dark stripes on the surface of the vehicle panels. This contrast makes defects on the vehicle panels clearer, making them easier for inspectors to detect and effectively improving the appearance inspection results of vehicle panels.

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.

[0025] Existing inspection lights are typically fixed in place. When inspecting panels of different shapes and locations, the lights need to be moved to different positions, resulting in poor flexibility and significantly limiting the efficiency of the inspection work. Furthermore, existing inspection lights often use a point light source design, leading to overly concentrated light that causes some areas of the vehicle panel to be too bright while other areas remain too dark, failing to clearly display the details of the panel surface and resulting in poor appearance inspection results.

[0026] This utility model proposes a mobile appearance inspection lamp, including a bracket 10, a lamp housing 20, and a light-transmitting plate 30. The bracket 10 includes two vertically arranged vertical rods 11, the bottom of each vertical rod 11 being connected to a base 12. A traveling wheel 121 is installed on the bottom of the base 12. Two vertically spaced connecting rods 13 are connected between the two vertical rods 11, with each connecting rod 13 arranged horizontally. The two vertical rods 11 and the two connecting rods 13 together enclose an installation space. The lamp housing 20 is installed within the installation space. The lamp housing 20 forms a receiving cavity, and multiple lamp tubes 21 are installed in the receiving cavity. The multiple lamp tubes 21 are arranged horizontally at intervals and each lamp tube 21 extends vertically. At least one side of the lamp housing 20 along the longitudinal direction has a light-transmitting opening 22 that communicates with the receiving cavity. A light-transmitting plate 30 is covered at the light-transmitting opening 22. The side where the light-transmitting plate 30 is located forms a detection side for detecting vehicle parts. Multiple light-shielding strips 31 are arranged at intervals on the light-transmitting plate 30, and a light-transmitting gap 32 is formed between any two adjacent light-shielding strips 31.

[0027] Please see Figure 1 and Figure 2 , Figure 1 The left and right directions in the middle are the horizontal directions. Figure 2 The front-to-back direction in the middle is the longitudinal direction. Figure 1 and Figure 2 The vertical direction is defined as the vertical direction. Two vertical rods 11 are supported on two bases 12 respectively. A connecting rod 13 connects the top of the two vertical rods 11, and another connecting rod 13 connects the middle of the two vertical rods 11. The two vertical rods 11 and the two connecting rods 13 together form an installation space for the stable installation of the lamp housing 20. Multiple lamp tubes 21 are installed horizontally at intervals inside the lamp housing 20, and each lamp tube 21 extends vertically, so that the multiple lamp tubes 21 are evenly distributed inside the lamp housing 20, providing uniform illumination for the vehicle's panels. A light-transmitting plate 30 is placed over the light-transmitting opening 22 to seal it. The light-transmitting plate 30 is made of transparent material and has multiple light-shielding strips 31. The multiple light-shielding strips 31 are spaced apart to form multiple spaced light-transmitting gaps 32, so that the light emitted by each lamp tube 21 shines out from the multiple light-transmitting gaps 32 and faces the inspection side to provide inspection light to the vehicle panel placed on the inspection side, thereby facilitating the inspection of the appearance quality of the vehicle panel.

[0028] The mobile appearance inspection lamp proposed in this utility model provides stable support for the lamp housing 20 through two vertical rods 11 and two connecting rods 13. The two vertical rods 11 are respectively connected to two bases 12, and the bases 12 are equipped with wheels 121, which can drive the lamp housing 20 to move via the bracket 10, so that the appearance inspection lamp can be moved to different positions to provide illumination for the appearance inspection of vehicle panels, effectively improving the flexibility of the appearance inspection lamp. Multiple lamp tubes 21 are arranged horizontally at intervals inside the lamp housing 20, and multiple light-shielding strips 31 are provided on the light-transmitting plate 30. A light-transmitting gap 32 is formed between any two adjacent light-shielding strips 31, so that the inspection light emitted by the lamp tubes 21 shines on the vehicle panels through the light-transmitting gap 32. When the inspection light emitted by multiple lamp tubes 21 shines out from the same light-transmitting gap 32, interference occurs, forming alternating light and dark stripes on the surface of the vehicle panels, thus creating a contrast between light and dark, making the defects on the surface of the vehicle panels clearer, making them easier for inspectors to detect, and effectively improving the appearance inspection effect of vehicle panels.

[0029] In one embodiment, the lamp housing 20 has two light-transmitting openings 22 on opposite sides along the longitudinal direction, and two light-transmitting plates 30 are respectively covered at the two light-transmitting openings 22 to form two detection sides. Multiple light-shielding strips 31 on one light-transmitting plate 30 are arranged laterally at intervals and each light-shielding strip 31 extends vertically. Multiple light-shielding strips 31 on the other light-transmitting plate 30 are arranged vertically at intervals and each light-shielding strip 31 extends laterally.

[0030] Understandably, the lamp housing 20 has two light-transmitting openings 22 on opposite sides along its longitudinal direction, forming two detection sides. A light-transmitting plate 30 is installed over each light-transmitting opening 22, allowing detection light to exit from both sides of the lamp housing 20 and illuminate the vehicle panels located on the two detection sides. Multiple light-shielding strips 31 on one light-transmitting plate 30 are spaced laterally, forming multiple light-transmitting gaps 32 to facilitate the formation of light and dark stripes spaced laterally. Multiple light-shielding strips 31 on the other light-transmitting plate 30 are spaced vertically, forming multiple light-transmitting gaps 32 spaced vertically. Through the two detection sides, the panels can be inspected laterally and vertically respectively, providing comprehensive multi-directional inspection of the panels. This meets the inspection needs of panels with different shapes and effectively improves the accuracy of surface inspection.

[0031] In one embodiment, the edge of each light-transmitting plate 30 is bonded to the edge of the light-transmitting opening 22 provided on the same side, and a sealing strip is provided at the bonding point between the light-transmitting plate 30 and the lamp housing 20.

[0032] It can be explained that the light-transmitting plate 30 and the light-transmitting opening 22 are bonded together to ensure a stable connection between the light-transmitting plate 30 and the lamp housing 20. The edge of the light-transmitting plate 30 abuts against the edge of the lamp housing 20 through a sealing strip to maintain the sealing of the internal environment of the lamp housing 20. This effectively prevents external dust, moisture and other impurities from entering the interior of the lamp housing 20 through the gap between the light-transmitting plate 30 and the lamp housing 20, extending the service life of the lamp tube 21 and ensuring the normal operation of the appearance inspection lamp.

[0033] In one embodiment, the lamp housing 20 has heat dissipation holes communicating with the receiving cavity on both sides along the lateral direction.

[0034] It should be noted that the lamp tube 21 generates a large amount of heat during continuous illumination. By opening heat dissipation holes in the lamp housing 20, the heat generated by the lamp tube 21 can be dissipated outwards through the heat dissipation holes, preventing localized heat accumulation inside the lamp housing 20. This helps maintain the stability of the internal temperature of the lamp housing 20, allowing the lamp tube 21 to operate in a relatively stable temperature environment. It can be noted that the heat dissipation holes can be sealed with a heat dissipation mesh, as is currently available, allowing air to circulate through the holes while trapping pollutants from the external environment, preventing them from entering the lamp housing 20.

[0035] In one embodiment, a plurality of lamps 21 are connected in series by cables, and a cable reel 40 for holding the cables is mounted on one of the vertical rods 11.

[0036] Understandably, multiple lamps 21 are connected in series via cables and connected to an external power source via cables, enabling the multiple lamps 21 to switch on and off synchronously. A cable reel 40 is installed on one of the vertical rods 11 to accommodate the cables. The cable reel 40 provides space for the cables, allowing them to be neatly stored within it. The length of the cable extending beyond the cable reel 40 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 40; after testing, the cable can be neatly retracted into the cable reel 40, maintaining the cleanliness and order of the equipment.

[0037] In one embodiment, a control cabinet 50 is mounted on one of the vertical poles 11, and the control cabinet 50 is electrically connected to each lamp tube 21 via a cable.

[0038] Furthermore, the control cabinet 50 is electrically connected to each lamp tube 21 via cables. The control cabinet 50 adopts the existing technology that can control the on / off state of the cables and the magnitude of the current. Operators can conveniently send control commands such as switching on and off and adjusting the brightness of each lamp tube 21 through the control cabinet 50, thereby realizing centralized and flexible control of the entire appearance inspection lights, and thus flexibly adjusting the illumination effect of the appearance inspection lights according to different vehicle parts.

[0039] In one embodiment, a diagonal strut 60 is connected between each base 12 and the vertical rod 11 attached thereto.

[0040] Please see Figure 2 An inclined support rod 60 is connected between the end of the base 12 and the vertical rod 11, forming a triangular support structure between the inclined support rod 60, the base 12 and the vertical rod 11. This effectively enhances the connection strength between the vertical rod 11 and the base 12, preventing the vertical rod 11 from tilting or swaying when subjected to external forces, thereby improving the structural stability of the bracket 10.

[0041] In one embodiment, a counterweight is installed at the bottom of the base 12. Furthermore, the counterweight installed at the bottom of the base 12 lowers the center of gravity of the entire appearance inspection light, thereby improving the stability of the entire appearance inspection light and preventing it from tipping over during movement.

[0042] In one embodiment, the traveling wheel 121 is a swivel wheel, and a braking device is provided on the traveling wheel 121.

[0043] Understandably, the casters can move the lamp tube 21 to the inspection position via the base 12, allowing the appearance inspection lamp to flexibly change direction during movement. This facilitates quick adjustment of the appearance inspection lamp's position by the operator according to actual inspection needs. The braking device can securely lock the casters, preventing the appearance inspection lamp from moving due to accidental contact or uneven ground during inspection, thereby improving the reliability and repeatability of the inspection. The braking device uses existing brake technology, which will not be described in detail here.

[0044] In one embodiment, the lamp tube 21 is an LED lamp tube 21, and a plurality of LED beads 211 are disposed on the lamp tube 21. The plurality of LED beads 211 are evenly distributed at intervals along the extension direction of the LED lamp tube 21, and the light-transmitting plate 30 is a glass plate.

[0045] It can be explained that the glass plate has good transparency and optical properties, ensuring efficient transmission of detection light. The lamp tube 21 adopts the existing LED lamp tube 21, with multiple LED beads 211 on each lamp tube 21 evenly distributed along the vertical interval, so that the light generated by the LED lamp tube 21 can evenly illuminate the surface of the board, providing good lighting conditions for detection and avoiding areas with excessively strong or weak light, thereby improving the accuracy and reliability of detection.

[0046] 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.
