Description

Technical Field

[0001] The invention belongs to the technical field of automobile rearview mirror production and manufacturing, and in particular relates to a laser testing device for automobile rearview mirror products. Background Art

[0002] Laser testing of automotive rearview mirrors utilizes laser technology to examine various performance indicators to ensure compliance with relevant standards and safety requirements, thereby ensuring driving safety. Key testing items include reflectivity, laser damage resistance, laser scattering, and optical distortion.

[0003] Currently, existing automotive rearview mirror testing technology lacks precise and effective positioning and fixing mechanisms in traditional loading and unloading methods. This results in the mirror holder being easily misaligned and shifted during loading and unloading, making it difficult to accurately position the mirror for testing, seriously affecting the accuracy of subsequent testing. Furthermore, the loading process relies heavily on manual labor, resulting in low efficiency and the potential for errors due to human error. This not only reduces loading efficiency but can also damage the tested mirror, increasing production costs and lead times.

[0004] In summary, the existing laser testing devices for automobile rearview mirrors have problems such as inaccurate positioning and fixation, large testing errors, low efficiency, and easy product damage. Summary of the Invention

[0005] The present invention provides a laser testing device for automobile rearview mirror products, which can solve the problems of inaccurate positioning and fixing, large testing errors, low efficiency and easy product damage in the laser testing device for automobile rearview mirror products in the prior art.

[0006] To achieve the above-mentioned object, according to an embodiment of the first aspect of the present invention, a laser testing device for an automobile rearview mirror product is provided, comprising a testing base; A laser test assembly, mounted on a test base, is used to measure the reflectivity of the rearview mirror to lasers of different wavelengths to evaluate its reflective performance; A transmission component is provided on the test base and is used for transporting the rearview mirror; Also includes: A pushing mechanism, the pushing mechanism includes a mounting base fixedly mounted on a base plate on the same side, a pushing cylinder fixedly mounted on the side of each mounting base, a pair of electric guide rails fixedly mounted on both sides of the surface of the test base, and a sliding plate arranged on the electric guide rail, a pair of track 2 fixedly mounted on the surface of each sliding plate, a plurality of track 1s distributed at equal intervals are provided on the transmission component, a notch is provided on the same side of each track 1 and track 2, a material seat is provided on the sliding plate, a sliding rod is fixedly mounted on the bottom surface of the material seat in conjunction with track 2, and a placement groove is provided on the surface of the material seat; The rearview mirror mold is arranged in the placement groove, and the surface of the rearview mirror mold is provided with a rearview mirror groove for placing the rearview mirror; The connecting and separating components are arranged on the material base and the pushing cylinder, and are used for connecting and separating the material base and the pushing cylinder.

[0007] A further improvement is that the laser testing assembly includes a pair of fixed plates fixedly mounted on one side of the surface of the test base and a laser reflectivity tester rotatably arranged in a port of the fixed plate. The test base is provided with a notch on one side of the fixed plate, and an adjusting cylinder is arranged in the notch. The bottom surface of the laser reflectivity tester and the bottom surface of the notch are both fixedly mounted with a connecting seat, the bottom end of the adjusting cylinder is rotatably arranged in the connecting seat port on the bottom surface of the notch through a rotating shaft, and the end of the rod body of the adjusting cylinder is rotatably arranged in the connecting seat port on the bottom surface of the laser reflectivity tester through a rotating shaft.

[0008] A further improvement is that the transmission component includes a pair of substrates fixedly mounted on the test base, a number of conveying rollers rotatably arranged on both sides of the substrate port and a conveyor belt wound around the conveying rollers, a pressure plate for supporting the conveyor belt is fixedly mounted on the inner side of the substrate, a DC servo motor is fixedly mounted on the substrate, the main shaft of the DC servo motor is connected to the conveying rollers, and a number of the tracks are fixedly mounted on the surface of the conveyor belt.

[0009] A further improvement is that each of the two sides of the sliding rod is fixedly installed with an adsorption magnetic block 1, and each track 2 and the inner wall of track 1 on the side away from the notch are fixedly installed with an adsorption magnetic block 2. The adsorption magnetic block 1 and the adsorption magnetic block 2 initially fix the material holder at a preset position on track 2 through magnetic adsorption.

[0010] A further improvement is that the connection and separation component includes a magnetic plate 1 fixedly installed on the bottom surface of the placement groove, protrusions arranged at the four corners of the surface of the magnetic plate 1 and a magnetic plate 2 fixedly installed on the bottom surface of the rearview mirror mold. Each of the protrusions and the magnetic plate 1 are integrated, and the bottom surface of the magnetic plate 2 is provided with a groove for matching the installation of each protrusion.

[0011] A further improvement is that the connection and separation component also includes a magnetic plate three fixedly installed on the same side of each material holder, and the rod of each pushing cylinder passes through the base plate, and a main magnet is fixedly installed at the end. The main magnet is attracted to the magnetic plate three when powered.

[0012] A further improvement is that it also includes a prompt component, which includes a mounting plate fixedly mounted on the side of each mounting seat, elastic touch switch 1 and elastic touch switch 2 fixedly mounted on the inner sides of the two mounting plates, a rubber strip fixedly mounted on the edge of the conveyor belt located on one side of the mounting seat, and several circular metal blocks fixedly mounted on the rubber strip at equal intervals; when the conveyor belt rotates, the contact blocks on the rubber strip at its edge contact the elastic touch switch 1 and elastic touch switch 2 in turn.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The present invention achieves the initial positioning of the material holder on the second track by inserting the bottom slide bar of the material holder into the second track port and using the adsorption magnetic blocks on the side of the slide bar and the inner wall of the second track for magnetic adsorption, effectively preventing deviation during the loading process, ensuring the accuracy of the loading position, and laying the foundation for the accuracy of subsequent tests. The material holder is automatically transported with the help of the electric guide rail at the bottom of the second track. During the transportation process, the conveying roller and the conveyor belt are driven by a DC servo motor to move at a constant speed. When the contact block triggers the elastic touch switch 1, the microprocessor can promptly control the motor to stop and start the push cylinder, and the subsequent contacts trigger signals in turn, realizing orderly automatic operation and improving the loading efficiency. After the push cylinder adsorbs and fixes the main magnet and the magnetic plate on the side of the material holder, the cylinder contracts to slide the bottom slide bar of the material holder into the first track on the surface of the conveyor belt, and is fixed by the adsorption magnetic block on the other side for a second magnetic attraction. This double fixing method enhances the stability of the material holder during transportation and ensures the smooth progress of the loading process.

[0014] After loading is complete, a conveyor belt transports the material holder to the testing area. The laser reflectivity tester then emits a laser beam to illuminate the rearview mirror surface, measuring the reflected light intensity and calculating the reflectivity. This simple and quick operation allows for rapid acquisition of rearview mirror reflectivity data. To collect data at different angles, an adjustable cylinder drives the laser reflectivity tester around its axis, changing the laser's incident angle. The reflected light intensity at each angle is measured and compared with the incident light intensity, ultimately outputting multiple sets of reflectivity data. This meets the needs of multi-angle testing, providing more comprehensive and accurate test results and enabling more precise evaluation of rearview mirror performance.

[0015] The present invention allows the edge contact block of the conveyor belt to trigger the second elastic touch switch when the test is completed. The microprocessor immediately controls the motor to stop and starts the push cylinder to push the material holder out. The bottom slide bar of the material holder slides along the track to the other side track and is fixed by magnetic attraction to complete the material discharge operation. The entire process is highly automated and does not require excessive human intervention, thereby improving the material discharge efficiency. Subsequent rearview mirrors perform material discharge operations in accordance with the same process, ensuring the orderliness of the material discharge process. The magnetic fixation method ensures the stability of the material holder during the material discharge process, avoiding problems such as confusion or material holder displacement. The design of the present invention reduces dependence on manual labor, reduces labor costs, and reduces the interference of human factors in the testing process, further improving the stability and consistency of the test.

The test base 1 is provided with an opening 101 on one side of the fixed plate 41, and an adjusting cylinder 43 is arranged in the opening 101. A connecting seat 44 is fixedly mounted on the bottom surface of the laser reflectivity tester 42 and the bottom surface of the opening 101. The bottom end of the adjusting cylinder 43 is rotatably arranged in the port of the connecting seat 44 on the bottom surface of the opening 101 through a rotating shaft, and the end of the rod of the adjusting cylinder 43 is rotatably arranged in the port of the connecting seat 44 on the bottom surface of the laser reflectivity tester 42 through a rotating shaft. By adjusting the extension and contraction of the rod of the adjusting cylinder 43, the laser reflectivity tester 42 is driven to rotate around the rotating shaft, thereby adjusting the angle of the laser reflectivity tester 42, so that the laser beam is irradiated to the surface of the rearview mirror at different angles, measuring the light intensity of the reflected light at different angles, and comparing it with the light intensity of the incident light to calculate the reflectivity; The transmission component 2 is arranged on the test base 1; Specifically, the transmission assembly 2 includes a pair of base plates 22 fixedly mounted on the test base 1, a plurality of conveying rollers 23 rotatably arranged on both sides of the inner port of the base plates 22, and a conveyor belt 21 wound around the conveyor rollers 23.

A DC servo motor is fixedly mounted on the base plates 22, and the main shaft of the DC servo motor is connected to the conveyor rollers 23. It should be noted that the laser test assembly 4 and the transmission assembly 2 are prior art. The embodiment of the present invention is implemented based on the above prior art and works together with the following pushing mechanism 3; The pushing mechanism 3 includes a mounting base 221 fixedly mounted on a base plate 22 on the same side, a pushing cylinder 31 fixedly mounted on the side of each mounting base 221, a pair of electric guide rails 33 fixedly mounted on both sides of the surface of the test base 1, and a sliding plate 35 arranged on the electric guide rail 33.

A notch is provided on the same side of each track 1 32. Each track 2 34 has a notch on the side of the track 1 32. A material seat 36 is provided on the sliding plate 35. A slide rod 302 is fixedly mounted on the bottom surface of the material seat 36 in conjunction with the track 2 34. A placement groove 301 is provided on the surface of the material seat 36. Specifically, each slide bar 302 is fixedly mounted with an adsorption magnetic block 1 303 on both sides, and each track 2 34 and track 1 32 is fixedly mounted with an adsorption magnetic block 2 304 on the inner wall on the side away from the notch. The adsorption magnetic blocks 1 303 and the adsorption magnetic blocks 2 304 use magnetic adsorption to initially fix the material holder 36 at a preset position on the track 2 34, or fix it to the track 1 32 of the conveyor belt 21 after feeding. It should be noted that there are several material holders 36. As the conveyor belt 21 rotates, the adjacent pair of tracks 1 32 and the pair of tracks 2 34 on each sliding plate 35 correspond to each other. Whenever a pair of tracks 1 32 and tracks 2 34 correspond to each other, the material holder 36 on the sliding plate 35 slides onto the conveyor belt 21. The rearview mirror mold 5 is placed in the placement groove 301, and the surface of the rearview mirror mold 5 is provided with a rearview mirror groove 51. like Figures 2 to 5 As shown, this embodiment also provides an implementation scheme, which is as follows: On the basis of the above embodiment, a connection and separation component 6 is further included. The connection and separation component 6 includes a magnetic plate 1 61 fixedly mounted on the bottom surface of the placement groove 301, protrusions 62 provided at the four corners of the surface of the magnetic plate 1 61, and a magnetic plate 2 63 fixedly mounted on the bottom surface of the rearview mirror mold 5.

Specifically, the connection and separation assembly 6 further includes a third magnetic plate 65 fixedly mounted on the same side of each material holder 36. The rod of each push cylinder 31 passes through the base plate 22, and a main magnet 66 is fixedly mounted at its end. When powered, the main magnet 66 is attracted to the third magnetic plate 65. like Figure 7 As shown, this embodiment also provides an implementation scheme, which is as follows: In addition to the above embodiment, a prompt assembly 7 is further included. The prompt assembly 7 comprises a mounting plate 71 fixedly mounted on the side of each mounting seat 221, a first elastic touch switch 72 and a second elastic touch switch 75 fixedly mounted on the inner sides of the two mounting plates 71, a rubber strip 73 fixedly mounted on the edge of the conveyor belt 21 located on one side of the mounting seat 221, and a plurality of circular metal blocks fixedly mounted on the rubber strip 73 at equal intervals. When the conveyor belt 21 rotates, the contact blocks 74 on the rubber strip 73 at its edge contact the first elastic touch switch 72 and the second elastic touch switch 75 in sequence. It should be noted that both elastic touch switch 1 72 and elastic touch switch 2 75 are microswitches that generate electrical signals when in contact with contact block 74. A microprocessor is fixedly mounted on the outer side of mounting plate 71. Elastic touch switch 1 72, elastic touch switch 2 75, the DC servo motor, and main magnet 66 are all connected by the microprocessor, receiving signals and controlling outputs. The principle of this circuit connection is conventional and will not be elaborated in this embodiment; it will be used directly.

[0020] like Figures 1 to 7 As shown in this embodiment, it should be noted that the actual dimensions of the components in the application document will be selected and installed according to actual on-site requirements before implementation. In addition, it should be noted that this application document only addresses the shortcomings of existing automotive rearview mirror product laser testing devices, such as inaccurate positioning and fixation, low automation leading to large testing errors, low efficiency, and easy product damage, and does not address other aspects. The following is an introduction to the working principle of this automotive rearview mirror product laser testing device: The use process of the solution of the present invention is divided into three steps: loading, testing and unloading. The on-site tester needs to operate the test device at the unloading area of ​​the automobile rearview mirror assembly workshop. The details are as follows: Step 1: loading process; Initial positioning: The tester places the test device at the rearview mirror unloading area in the workshop, places the rearview mirrors to be tested one by one into the rearview mirror groove 51 of the rearview mirror mold 5, and then places the entire mold together with the rearview mirror into the placement groove 301 of the material holder 36.

[0021] Pre-fixation: Insert the slide bar 302 at the bottom of the material holder 36 into the port of the track 2 34 on the surface of the test base 1, and achieve the initial positioning of the material holder 36 on the track 2 34 through magnetic adsorption of the adsorption magnetic block 1 303 on the side of the slide bar 302 and the adsorption magnetic block 2 304 on its inner wall to prevent the loading from deflecting.

[0022] Track Conveying: The motorized guide rail 33 at the bottom of track 2 34 transports the material holder 36 to the designated location. During conveying, a DC servo motor drives the conveyor rollers 23 and conveyor belt 21 to move at a constant speed. When a contact block 74 on the rubber strip 73 at the edge of the conveyor belt 21 triggers the elastic touch switch 1 72, an external microprocessor immediately stops the motor and activates the push cylinder 31. Subsequently, each alternate contact block 74 sequentially contacts the elastic touch switch 1 72, triggering a signal.

[0023] Magnetic Transfer: The push cylinder 31 extends, causing the main magnet 66 to contact the magnetic plate 3 65 on the side of the material holder 36. The main magnet 66 is then powered on to generate a magnetic field, which attracts and secures the two. The cylinder then retracts, causing the slide bar 302 at the bottom of the material holder 36 to slide along the track 2 34 to the pair of tracks 1 32 on the surface of the conveyor belt 21. A secondary magnetic attraction occurs between the magnetic plate 1 303 on the other side of the slide bar 302 and the magnetic plate 2 304 on the inner wall of track 1 32, completing the loading of a single rearview mirror. Subsequent rearview mirrors are loaded in this same process.

[0024] Step 2: Testing process; Reflectivity detection: After loading is completed, the conveyor belt 21 transports the material holder 36 to the testing area, and the laser reflectivity tester 42 emits a laser beam to illuminate the surface of the rearview mirror and calculates the reflectivity by measuring the reflected light intensity.

[0025] Multi-angle acquisition: If data at different angles needs to be collected, adjust the cylinder 43 to drive the laser reflectivity tester 42 to rotate around the axis, change the laser incident angle, measure the reflected light intensity at each angle and compare it with the incident light intensity, and finally output multiple sets of reflectivity data.

[0026] Step 3: Cutting process; When the first tested rearview mirror is delivered to the other side of the test base 1 for unloading, the contact block 74 on the rubber strip 73 at the edge of the conveyor belt 21 triggers the elastic touch switch 2 75, and the external microprocessor immediately controls the motor to stop rotating and activates the push cylinder 31 to push out the material holder 36. The slide bar 302 at the bottom of the material holder 36 slides along the track 1 32 on the surface of the conveyor belt 21 to the track 2 34 on the surface of the sliding plate 35 on the other side until the magnetic block 1 303 on the side of the slide bar 302 is magnetically fixed to the magnetic block 2 304 on the inner wall of the track 2 34, completing the unloading of a single rearview mirror. Subsequent rearview mirrors are unloaded in sequence, completing the entire testing process.

[0027] The above embodiments are only used to illustrate the technical method of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
