Description

Technical Field

[0001] This utility model relates to the field of reflectivity testing instruments, and in particular to a reflectivity testing instrument. Background Technology

[0002] In the coatings industry, color difference is a key factor affecting product quality and market acceptance. As an important tool for accurately measuring color difference, the performance of a coating reflectance tester directly impacts quality control and R&D innovation. Existing technology discloses a coating reflectance testing device (application number 202220745426.X), which defines a test space within a test chamber that surrounds the light source, test plate support, and testing instruments. A matte material layer is provided on the walls of the test space to prevent external environmental influences, simulating cloudy natural light conditions. However, this existing technology can only perform tests at a single fixed angle, failing to meet multi-angle measurement needs and comprehensively reflecting the reflective characteristics of coatings at different viewing angles, leading to biased measurement results. Therefore, we propose a reflectance tester to solve these problems. Utility Model Content

[0003] In response to the shortcomings of the above-mentioned problems, this utility model provides a reflectivity tester that enables multi-angle, high-precision reflectivity testing of coating samples to meet more complex testing needs and overcome the limitations of existing technologies in terms of testing flexibility and comprehensiveness.

[0004] To solve the above problems, the technical solution provided by this utility model is as follows:

[0005] A reflectivity tester includes a base, a light source emitter, and a testing instrument. From left to right, the upper end of the base is provided with a support frame, a glass mechanism, a lifting and adjusting cylinder for the testing instrument, and a movable seat. A fixing mechanism is located above the movable seat. A slot is formed in the base, within which a servo motor and a lead screw are installed. The output end of the servo motor is fixedly connected to the left end of the lead screw, and the right end of the lead screw is rotatably connected to the inner wall of the slot. A movable threaded sleeve is threaded onto the lead screw and fixedly installed at the lower end of the movable seat. A top frame is fixedly installed at the upper end of the support frame, and a hydraulic cylinder is mounted on the top frame. The output end of the hydraulic cylinder is fixedly connected to the lifting frame. The light source emitter is installed below the lifting frame. A propulsion cylinder is provided on the base, and its output end is connected to the glass mechanism. The testing instrument is installed to the right of the output end of the lifting and adjusting cylinder for the testing instrument.

[0006] Furthermore, the glass mechanism includes a glass plate, a glass mounting side frame, and a glass mounting base. The two sides of the glass plate are fixedly connected to the glass mounting base via the glass mounting side frame. A slider is provided at the lower end of the glass mounting base. A sliding groove is provided on the base corresponding to the position of the slider. The slider is slidably connected to the sliding groove in the left and right directions. The output end of the propulsion cylinder is fixedly connected to the glass mounting base.

[0007] Furthermore, a rotating motor is installed on the right side of the fixing mechanism.

[0008] Furthermore, the fixing mechanism includes a connecting platform, a turntable, a vertical plate, a push rod, a clamping plate adjusting seat, a clamping plate drive motor, and a clamping plate. The rotating motor is fixedly installed on the right side of the turntable, and the output shaft of the rotating motor is fixedly connected to the connecting platform. The connecting platform is rotatably connected to the turntable, and the lower end of the turntable is fixedly connected to the movable seat. The vertical plates are symmetrically arranged on both sides of the connecting platform. A push rod is installed between the vertical plate and the clamping plate adjusting seat. The output end of the push rod is fixedly connected to the clamping plate adjusting seat, and the clamping plate adjusting seat is slidably connected to the connecting platform. A clamping plate drive motor is installed on the clamping plate adjusting seat, and the output end of the clamping plate drive motor is fixedly connected to the clamping plate.

[0009] Furthermore, a rubber pad is provided on the inner side of the clamping plate.

[0010] Furthermore, a triangular fixing plate is fixedly installed on the glass mounting side frame.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] 1. The rotating motor on the right side of the fixed mechanism drives the turntable to rotate the sample in all directions. Combined with the layout of the light source and testing instruments, it can obtain reflectivity data from different angles, which solves the limitation of single-angle testing and makes the measurement results more comprehensive.

[0013] 2. The testing instrument's lifting and adjusting cylinder, servo motor lead screw moving seat, and glass mechanism controlled by the propulsion cylinder can adjust the height and horizontal position of the testing instrument, change the relative position of the glass, adapt to various samples, simulate different optical environments, meet complex testing needs, and improve testing accuracy.

[0014] In summary, this reflectivity tester has broad applicability, addressing the problem that existing technologies mentioned in the background art can only perform tests at a single fixed angle, failing to meet the needs of multi-angle measurements and comprehensively reflecting the reflectivity characteristics of coatings at different viewing angles, resulting in biased measurement results.

Detailed Implementation

[0021] To make the objectives, technical solutions and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and examples, but the examples given are not intended to limit the present utility model.

[0022] like Figures 1-4 As shown, the embodiment of this utility model includes a base 1, a light source emitter 6, and a testing instrument 9.

The slider 704 is slidably connected to the sliding groove. The output end of the propulsion cylinder 8 is fixedly connected to the glass mounting base 703. A triangular fixing plate 705 is fixedly installed on the glass mounting side frame 702. By extending and retracting the propulsion cylinder 8, the glass mechanism 7 can be pushed to move left and right on the base 1, thereby adjusting the position of the glass plate 701.

[0025] The testing instrument 9 is installed on the right side of the output end of the testing instrument lifting and adjusting cylinder 10. By extending and retracting the testing instrument lifting and adjusting cylinder 10, the height of the testing instrument 9 can be adjusted to adapt to different testing scenarios.

[0026] The fixing mechanism 12 is set above the movable base 11. The base 1 has a slot 101. The servo motor 14 and the lead screw 15 are installed in the slot 101. The output end of the servo motor 14 is fixedly connected to the left end of the lead screw 15. The right end of the lead screw 15 is rotatably connected to the inner wall of the slot 101. A movable threaded sleeve 16 is threaded onto the lead screw 15. The movable threaded sleeve 16 is fixedly installed at the lower end of the movable base 11. When the servo motor 14 is started, it drives the lead screw 15 to rotate. The movable threaded sleeve 16 threaded onto the lead screw 15 is fixed at the lower end of the movable base 11. The rotation of the lead screw 15 causes the movable threaded sleeve 16 to move along the lead screw 15, thereby driving the movable base 11 to move back and forth on the base 1.

[0027] A rotary motor 13 is installed on the right side of the fixing mechanism 12. The fixing mechanism 12 includes a connecting platform 1201, a turntable 1202, a vertical plate 1203, a push rod 1204, a clamping plate adjusting seat 1205, a clamping plate drive motor 1206, and a clamping plate 1207. The rotary motor 13 is fixedly installed on the right side of the turntable 1202. The output shaft of the rotary motor 13 is fixedly connected to the connecting platform 1201. The connecting platform 1201 is rotatably connected to the turntable 1202. The lower end of the turntable 1202 is fixedly connected to the movable seat 11. Next, vertical plates 1203 are symmetrically arranged on both sides of the connecting platform 1201. A push rod 1204 is installed between the vertical plate 1203 and the clamping plate adjusting seat 1205. The output end of the push rod 1204 is fixedly connected to the clamping plate adjusting seat 1205. The clamping plate adjusting seat 1205 is slidably connected to the connecting platform 1201. A clamping plate drive motor 1206 is installed on the clamping plate adjusting seat 1205. The output end of the clamping plate drive motor 1206 is fixedly connected to the clamping plate 1207. A rubber pad is provided on the inner side of the clamping plate 1207.

[0028] The rotating motor 13 is fixed on the right side of the turntable 1202, and its output shaft is fixedly connected to the connecting platform 1201. By rotating the rotating motor 13, the connecting platform 1201 can be driven to rotate relative to the turntable 1202, thereby adjusting the angle of the fixing mechanism 12.

[0029] Vertical plates 1203 are symmetrically arranged on both sides of the connecting platform 1201. The push rod 1204 between the vertical plate 1203 and the clamp adjustment seat 1205 can push the clamp adjustment seat 1205 to slide on the connecting platform 1201 to adjust the lateral position of the clamp 1207.

[0030] The clamp drive motor 1206 on the clamp adjustment seat 1205 can drive the clamp 1207 to rotate or move. The rubber pad on the inner side of the clamp 1207 can increase the friction with the object to be tested, while avoiding damage to the surface of the object, thus achieving a firm fixation of the object to be tested.

[0031] 1. The object to be tested is fixed.

[0032] Start the servo motor 14 to move the moving base 11 to the appropriate position.

[0033] The control push rod 1204 adjusts the position of the clamp adjustment seat 1205, and the clamp drive motor 1206 is started, so that the clamp 1207 clamps and fixes the object to be measured. If necessary, the rotation motor 13 can be started to adjust the angle of the fixing mechanism 12.

[0034] 2. Adjustment of the position of the light source and testing instruments

[0035] The height of the light source emitter 6 is adjusted by hydraulic cylinder 4.

[0036] The height of the testing instrument 9 is adjusted using the lifting and adjusting cylinder 10 of the testing instrument.

[0037] Glass mechanism position adjustment: Start the propulsion cylinder 8 to push the glass mechanism 7 to the appropriate position.

[0038] 3. Reflectivity test: The light source emitter 6 is turned on to emit light. The light shines on the surface of the object to be tested. After reflection, it is received by the testing instrument 9. The testing instrument 9 analyzes the reflected light to obtain the reflectivity of the object.
