Description

Technical Field

[0001] This utility model relates to the field of spraying, and in particular to an automatic color difference comparison lighting box for sprayed parts. Background Technology

[0002] Liquid coatings only form a protective or decorative coating on the substrate after application. After application and curing, the appearance, color, and performance of the coating film must be inspected. Color is the most visually apparent difference, and color variation is a crucial factor affecting the film's appearance and even its overall quality. Furthermore, color variation is not only strictly controlled after application, but it is also a mandatory and critical aspect of coating product development, color adjustment, and production testing.

[0003] In the common process of car paint repair and painting, the traditional comparison method used by car mechanics is to compare the painted part with a color difference comparison board. However, the recognition accuracy of visual inspection is inherently flawed, and the influence of ambient light will greatly affect the overall inspection accuracy. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figs. 1-3 An automatic color difference comparison lighting box for sprayed parts includes a comparison box 1 and a colorimeter 5 installed inside the comparison box 1. The front of the comparison box 1 is provided with a placement slot 2. A protective cover plate 3 matching the front of the placement slot 2 is also provided on the front of the comparison box 1. A placement seat 4 is installed at the bottom of the placement slot 2 on the front of the comparison box 1. The colorimeter 5 is installed on the inner wall of the placement slot 2. A control panel 6 is also provided on the front of the upper part of the comparison box 1. An lighting port 7 communicating with the placement slot 2 is provided at the bottom of the inner cavity of the upper part of the comparison box 1. A rotating shaft 8 is provided for horizontal rotation of the inner cavity of the upper part of the comparison box 1. Multiple sets of arc-shaped lamp holders 9 are fixedly installed on the outside of the rotating shaft 8. A lighting lamp 10 is installed at the bottom of the lamp holder 9. Baffles 11 are connected to the inner wall of the upper part of the comparison box 1 on both sides of the lighting port 7, and the arc-shaped lamp holders 9 are engaged between the baffles 11 and connected to the lighting port 7.

[0022] It should be added that the bottom of the placement seat 4 is connected to the bottom of the placement slot 2 via a motor. The motor can rotate and adjust the rotation of the sprayed parts placed on the upper part of the placement seat 4, facilitating color difference comparison at multiple locations. Furthermore, the control panel 6 on the front of the comparison box 1 includes a motor switch and a switch for the lighting lamp 10, facilitating operation by staff. It should also be noted that the colorimeter 5 is a common colorimeter model available on the market, and will not be specified or elaborated upon here.

[0023] One end of the rotating shaft 8 is movably connected to the comparison box 1 and fixedly connected to a first handle 801, facilitating the rotation of the rotating shaft 8 to switch between different lamp holders 9 and the bottom lighting lamp 10. The upper end of the baffle 11 has an arc-shaped surface design, and the arc-shaped surface of the upper end of the baffle 11 contacts and cooperates with the arc-shaped lamp holder 9. The bottom of the baffle 11 is provided with a storage groove, and the inner wall of the storage groove is connected to the inner wall of the upper part of the comparison box 1 by a spring telescopic pin 1101. The spring telescopic pin 1101 is in the extended state by default. When the rotating shaft 8 rotates to switch between different light sources, the first handle 801 drives the rotating shaft 8 to rotate, and the arc-shaped lamp holder 9 on the outer side of the rotating shaft 8 rotates accordingly. The arc-shaped lamp holder 9 contacts the arc-shaped surface of the upper end of the baffle 11 and presses the baffle 11, while compressing the spring telescopic pin 1101. When the lamp holder 9 is inserted between the two sets of baffles 11, the elastic restoring force of the spring telescopic pin 1101 drives the baffle 11 to rise, stably locking the lamp holder 9 between the two sets of baffles 11, and connecting it to the upper end of the lighting port 7 to illuminate the bottom of the sprayed part. Different illumination light sources (the lighting lamp 10 can be selected from daylight simulation lamps, incandescent lamps, and ultraviolet lamps) are switched for color difference comparison.

[0024] The comparison box 1 is fixedly connected to two sets of mounting seats 12 on the inner wall of the placement slot 2. The colorimeter 5 is fixedly connected to the mounting shafts 1201 on both sides by bolts. The mounting shafts 1201 on both sides are rotatably connected to the inner walls of the two sets of mounting seats 12. One set of mounting shafts 1201 extends to the outside of the mounting seat 12 after passing through it. The outer end of the set of mounting shafts 1201 is fixedly connected to a second handle 1202. A threaded pin 1204 is provided through the outer side of the second handle 1202. The outer side of the mounting seat 12 corresponding to the second handle 1202 is provided with multiple sets of positioning holes 1203. The threaded pin 1204 is threaded into the positioning hole 1203. Considering that the detection angle of the colorimeter is different when comparing different spraying materials, the operator can first rotate the threaded pin 1204 to disengage it from the positioning hole 1203. Then, the detection angle of the colorimeter 5 can be adjusted by rotating the mounting shaft 1201. After adjustment, the threaded pin 1204 can be inserted into the corresponding positioning hole 1203 to maintain the stability of the colorimeter 5.

[0025] Based on the above structural design, when using this device, the operator places the sprayed part to be tested on the upper part of the placement base 4, pre-selects and adjusts the illumination light source 10, and simultaneously adjusts the detection angle of the colorimeter 5. Then, a standard color card is aligned with the bottom of the colorimeter 5 and the standard color is recorded. The colorimeter 5 is then used to detect the color on the surface of the sprayed part on the upper part of the placement base 4 and compared with the standard color to obtain the first result. Subsequently, different illumination lights 10 are switched for a second comparison, and this process is repeated. All results are recorded uniformly to facilitate the final comparison conclusion. Simultaneously, the placement base 4 can be rotated to compare the color of other parts of its surface, resulting in a better comparison effect.

[0026] It should be added that the inner wall of the comparison box 1 is equipped with an anti-reflection layer to reduce light reflection interference. Additionally, the protective cover 3 can be closed during testing to prevent interference from external light sources. (The protective cover is connected to the comparison box via hinges and latches.)
