Description

Technical Field

[0001] This invention belongs to the field of automotive parts measurement technology, and specifically relates to a laser measurement device for the dimensions of injection-molded automotive headlights. Background Technology

[0002] Automotive lamp covers are injection-molded transparent plastic parts. Their shape, curvature, and overall dimensional accuracy directly affect the sealing performance, appearance gaps, and overall vehicle assembly effect when assembled with the lamp housing. Currently, dimensional inspection of automotive lamp covers after injection molding relies heavily on manual single-point measurements using conventional measuring tools. This method suffers from low measurement efficiency, large human error, and poor data consistency, making it difficult to meet the inspection requirements of mass production.

[0003] A search revealed that Chinese Patent Publication No. CN104266621B, authorized on August 8, 2017, discloses a device for measuring the dimensions of a vehicle headlight housing. This device uses five support components on a base to house seven measuring gauges for measuring the dimensions of various parts of the headlight housing, resulting in high efficiency compared to previous methods that measured each component sequentially. Furthermore, the contact between the measuring probe of each gauge and the headlight is controlled by steel wire ropes, each connected to a steel wire rope switch mechanism. This mechanism allows for convenient and rapid control of the tension of all steel wire ropes, thereby controlling the contact of the measuring probes and initiating or stopping the measurement. The device is highly convenient and accurate; simply installing the headlight housing and turning on the switch quickly yields all the dimensional data. This invention features a simple structure, is easy to operate, improves production efficiency, saves labor costs, and provides rapid and accurate measurements, making it suitable for measuring vehicle headlight housings.

[0004] However, the equipment still has the following drawbacks: For automotive lamp covers with complex curved shapes, in order to complete the measurement of the inner and outer wall dimensions of the lamp cover, it is usually necessary to manually disassemble and flip the workpiece repeatedly. This is not only cumbersome and labor-intensive, but also easy to cause scratches and deformation on the surface of the lamp cover during the flipping process, affecting the detection accuracy and product appearance quality.

[0015] In one embodiment of this application, the hinge includes a first pin seat, a second pin seat, and a connecting rod. The first pin seat is fixedly installed on the support block, and the second pin seat is fixedly installed on the bottom of the support plate. A pin shaft is rotatably installed on both the first and second pin seats. One end of the connecting rod is hinged to the first pin seat via the pin shaft, and the other end of the connecting rod is hinged to the second pin seat via the pin shaft.

[0016] In one embodiment of this application, the surface of the boss is provided with a flexible buffer layer, and the surface of the flexible buffer layer is provided with clearance holes corresponding to the vacuum suction cup nozzle.

[0017] In one embodiment of this application, the motion mechanism includes a first electric slide, a second electric slide, and a third electric slide fixedly mounted on a bracket. The third electric slide is fixedly mounted on the side of the second electric slide, and the second electric slide is fixedly mounted on the sliding part of the first electric slide. Two sets of laser three-dimensional contour sensors are respectively fixedly mounted on the sliding parts of the second electric slide and the third electric slide.

[0018] In one embodiment of this application, a rotating member is provided on the support plate, and the rotating member is used to drive the boss to rotate;

[0019] The rotating component includes a second motor, a driving component, a bearing, and a fixed tube. The fixed tube passes through the surface of the support plate. The second motor is fixedly mounted on the support plate, and the rotating component is located inside the boss. The second motor is connected to the driving component for transmission. The inner ring of the bearing is fixedly sleeved on the fixed tube, and the bearing is connected to the driving component.

[0020] In one embodiment of this application, a barrier is provided on the table of the machine tool, and the inner sidewall of the barrier is covered with a sound-absorbing cotton board; a dust blowing nozzle is fixedly installed on the third electric slide, the orientation of the dust blowing nozzle is consistent with the detection direction of the laser three-dimensional contour sensor, and the dust blowing nozzle is connected to a high-pressure air pump through an air pipe.

[0021] In one embodiment of this application, the driving component includes a connecting pipe, a first gear and a second gear, the first gear being connected to a second motor for transmission, the first gear meshing with the second gear, the second gear being fixedly sleeved on the outer wall of the connecting pipe, and the outer ring of the bearing being fixedly connected to the inner wall of the connecting pipe.

[0022] In one embodiment of this application, a spring is provided on the side of the vacuum suction cup away from the suction nozzle, and one end of the spring is fixedly connected to the boss.

[0023] The beneficial effects of this invention are:

[0024] 1. After measuring the outer wall of the headlight cover, the first motor rotates, driving the screw to rotate. The hinge limits the support blocks, causing the two support blocks to move linearly along the screw as it rotates. This drives the connecting rod to rotate around the pin, pushing the two support plates to rotate relative to each other. This causes the headlight cover on the boss to rotate 90°, while the boss on the other support plate contacts the rotated headlight cover. The vacuum suction cup on the boss then adheres to the outer wall of the headlight cover. At this point, the vacuum suction cup used to adhere to the inner wall of the headlight cover stops adhering to it. The first motor rotates in the opposite direction, causing the two support plates to reset, thus completing the rotation of the headlight cover. This process reduces manual operation, lowers the workload of workers, and reduces errors caused by manual operation.

[0025] 2. When measuring the outer wall of the headlight cover, the use of the first, second, and third electric slides, along with the flipping mechanism and rotating parts, allows for comprehensive internal and external measurements of the headlight cover, improving measurement quality, reducing manual operation, and increasing measurement efficiency.

[0026] 3. By using the rotating component, when inspecting the outer wall of the headlight cover, the second motor drives the first gear to rotate, which in turn drives the second gear to rotate, thereby causing the boss and bearing to rotate together. This causes the third electric slide to drive the laser three-dimensional contour sensor to perform a comprehensive measurement of the outer wall of the headlight cover. In conjunction with the measurement components, a comprehensive measurement of the outer wall of the headlight cover can be performed, which can improve the measurement quality of the headlight cover.

[0027] 4. When the headlight cover is pressed onto the vacuum suction cup, the spring is compressed, and the vacuum suction cup is pressed into the clearance hole. Through the support of the spring, the vacuum suction cup can be pushed to contact the headlight cover. After the headlight cover is removed, the spring can drive the vacuum suction cup to return to its original position, so that the vacuum suction cup protrudes from the boss, ensuring that the vacuum suction cup can contact the headlight cover. When the vacuum suction cup is working, it can ensure the adsorption effect of the vacuum suction cup on the headlight cover.

Detailed Implementation

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] This invention provides a laser measurement device for the dimensions of injection-molded automotive headlights, see reference. Figures 1-9 It includes a machine base 1, a support 2, a measuring component 3, and a fixing mechanism 4;

[0042] The bracket 2 is fixedly installed on the machine base 1;

[0043] The measuring component 3 includes a laser three-dimensional contour sensor 301 and a motion mechanism 302. The motion mechanism 302 is mounted on the support 2, and the laser three-dimensional contour sensor 301 is mounted on the motion mechanism 302. Two sets of laser three-dimensional contour sensors are provided.

[0044] The fixing mechanism 4 includes a support plate 401 and a flipping mechanism 402. The support plate 401 is rotatably mounted on the machine base 1 via a first bearing seat 403. The flipping mechanism 402 is disposed inside the machine base 1 and is used to flip the support plate 401.

[0045] The support plate 401 is provided with a protrusion 404 that fits into the headlight cover;

[0046] A vacuum suction cup 405 is provided on the boss 404;

[0047] The vacuum suction cup 405 is used to adsorb and fix the headlight cover.

[0048] It should be noted that the boss 404 has a cavity inside;

[0049] When the headlight cover is placed on the boss 404, the contact parts between the boss 404 and the inner and outer walls of the headlight cover can fit together.

[0050] There are two support plates 401 and two bosses 404. The two bosses 404 are respectively used to contact the inner wall of the headlight cover and the outer wall of the headlight cover.

[0051] A spring 9 is provided on the side of the vacuum suction cup 405 away from the suction nozzle, and one end of the spring 9 is fixedly connected to the boss 404.

[0052] Spring 9 is used to support vacuum suction cup 405;

[0053] When the headlight cover is pressed onto the vacuum suction cup 405, the spring 9 is compressed, and the vacuum suction cup 405 is pressed into the clearance hole. Through the support of the spring 9, the vacuum suction cup 405 can be pushed to contact the headlight cover. After the headlight cover is removed, the spring 9 can drive the vacuum suction cup 405 to return to its original position, so that the vacuum suction cup 405 protrudes from the boss 404, ensuring that the vacuum suction cup 405 can contact the headlight cover. When the vacuum suction cup 405 is working, it can ensure the adsorption effect of the vacuum suction cup 405 on the headlight cover.

[0054] Using the above solution, when performing laser measurement on the headlight cover, the motion mechanism 302 drives the laser three-dimensional contour sensor 301 to move and measure the size of the headlight cover. No manual measurement is required, which can improve accuracy and work efficiency. At the same time, the headlight cover is flipped by the flipping mechanism 402, which can measure the size of the inner wall of the headlight cover. It can measure both the inner and outer walls of the headlight cover and complete the headlight cover measurement, thus improving the accuracy and quality of the measurement.

[0055] For example, the flipping mechanism 402 includes a support rod 4021, a first motor 4022, a transmission component 4023, and a hinge component 4024. The first motor 4022 is fixedly mounted on the support rod 4021 and is connected to the transmission component 4023. One end of the hinge component 4024 is disposed on the transmission component 4023, and the other end of the hinge component 4024 is disposed at the bottom of the support plate 401.

[0056] The transmission component 4023 includes a second bearing seat 40231, a screw 40232, and a support block 40233. The end of the screw 40232 is rotatably mounted in the second bearing seat 40231, and the second bearing seat 40231 is fixedly mounted on the support rod 4021. The support block 40233 is threadedly connected to the screw 40232, and the screw 40232 is drive-connected to the first motor 4022.

[0057] It should be noted that there are two support blocks 40233, and the two support blocks 40233 move in opposite directions when the screw 40232 rotates;

[0058] The hinge 4024 includes a first pin seat 40241, a second pin seat 40242, and a connecting rod 40243. The first pin seat 40241 is fixedly installed on the support block 40233, and the second pin seat 40242 is fixedly installed on the bottom of the support plate 401. A pin shaft 40244 is rotatably installed on both the first pin seat 40241 and the second pin seat 40242. One end of the connecting rod 40243 is hinged to the first pin seat 40241 through the pin shaft 40244, and the other end of the connecting rod 40243 is hinged to the second pin seat 40242 through the pin shaft 40244.

[0059] Using the above scheme, after completing the measurement of the outer wall of the headlight cover, the first motor 4022 rotates, driving the screw 40232 to rotate. The hinge 4024 limits the support block 40233, causing the two support blocks 40233 to move linearly along the screw 40232 as it rotates. This drives the connecting rod 40243 to rotate around the pin 40244, thereby pushing the two support plates 401 to rotate relative to each other, causing the headlight cover on the boss 404 to flip 9 degrees. At 0°, the boss 404 on the other support plate 401 contacts the headlight cover that has been rotated 90°. The vacuum suction cup 405 on the boss 404 adsorbs the outer wall of the headlight cover. At this time, the vacuum suction cup 405 used to adsorb the inner wall of the headlight cover stops adsorbing the headlight cover. The first motor 4022 rotates in the opposite direction, driving the two support plates 401 to reset, thereby completing the rotation of the headlight cover. This can reduce manual operation, reduce the workload of workers, and reduce the error caused by manual operation.

[0060] To prevent wear on the outer or inner wall when the headlight cover comes into contact with the boss 404 during measurement, a flexible buffer layer is provided on the surface of the boss 404. The surface of the flexible buffer layer has clearance holes corresponding to the suction nozzle of the vacuum suction cup 405. The flexible buffer layer is made of rubber.

[0061] For example, the motion mechanism 302 includes a first electric slide 3021, a second electric slide 3022, and a third electric slide 3023 fixedly mounted on a bracket. The third electric slide 3023 is fixedly mounted on the side of the second electric slide 3022, and the second electric slide 3022 is fixedly mounted on the sliding part of the first electric slide 3021. Two sets of laser three-dimensional contour sensors 301 are respectively fixedly mounted on the sliding parts of the second electric slide 3022 and the third electric slide 3023.

[0062] Using the above scheme, when measuring the outer wall of the headlight cover, the use of the first electric slide 3021, the second electric slide 3022 and the third electric slide 3023 allows the third electric slide 3023 to follow the movement of the second electric slide 3022 when the first electric slide 3021 moves. When the second electric slide 3022 and the third electric slide 3023 are working, the laser three-dimensional contour sensor 301 can be driven to perform laser measurement on the outer wall of the headlight cover.

[0063] When measuring the outer wall of the headlight cover, the first electric slide 3021 can drive the second electric slide 3022 to move. The second electric slide 3022 works to drive the optical three-dimensional contour sensor to perform laser measurement on the inner wall and edge of the headlight cover.

[0064] It can comprehensively measure the inside and outside of the headlight cover, which can improve measurement quality, reduce manual operation, and improve measurement efficiency.

[0065] For example, the support plate 401 is provided with a rotating member 5, which is used to drive the boss 404 to rotate;

[0066] The rotating component 5 includes a second motor 501, a driving component 502, a bearing 503, and a fixing tube 504. The fixing tube 504 passes through the surface of the support plate 401. The second motor 501 is fixedly installed on the support plate 401, and the rotating component 5 is located inside the boss 404. The second motor 501 is connected to the driving component 502 in a transmission connection. The inner ring of the bearing 503 is fixedly sleeved on the fixing tube 504, and the bearing 503 is connected to the driving component 502.

[0067] It should be noted that the fixing tube 504 penetrates through the support plate 401;

[0068] The driving component 502 includes a connecting pipe 5021, a first gear 5022 and a second gear 5023. The first gear 5022 is connected to the second motor 501 for transmission. The first gear 5022 meshes with the second gear 5023. The second gear 5023 is fixedly sleeved on the outer wall of the connecting pipe 5021. The outer ring of the bearing 503 is fixedly connected to the inner wall of the connecting pipe 5021.

[0069] The tubing of the vacuum suction cup 405 can pass through the connecting tube 5021 and the fixing tube 504.

[0070] By adopting the above scheme, when the outer wall of the headlight cover is inspected by the use of the rotating component 5, the second motor 501 drives the first gear 5022 to rotate, which in turn drives the second gear 5023 to rotate. This causes the boss 404 and the bearing 503 to rotate together, and the third electric slide 3023 drives the laser three-dimensional contour sensor 301 to perform a comprehensive measurement of the outer wall of the headlight cover. This is linked with the measurement component 3 to perform a comprehensive measurement of the outer wall of the headlight cover, which can improve the measurement quality of the headlight cover.

[0071] For example, a barrier 6 is provided on the table surface of the machine 1, and the inner side wall of the barrier 6 is covered with a sound-absorbing cotton board 7; a dust-blowing nozzle 801 is fixedly installed on the third electric slide 3023, the orientation of the dust-blowing nozzle 801 is consistent with the detection direction of the laser three-dimensional contour sensor 301, and the dust-blowing nozzle 801 is connected to a high-pressure air pump 802 through an air pipe. By using the dust-blowing nozzle 801, air can be blown on the lamp cover to reduce surface dust and improve measurement quality. By using the sound-absorbing cotton board 7, wind noise can be reduced.

[0072] In summary, based on the above embodiments, the beneficial effects of this application are as follows:

[0073] After measuring the outer wall of the headlight cover, the first motor 4022 rotates, driving the screw 40232 to rotate. The hinge 4024 limits the support block 40233, causing the two support blocks 40233 to move linearly along the screw 40232 when the screw 40232 rotates. This causes the connecting rod 40243 to rotate around the pin 40244, thereby pushing the two support plates 401 to rotate relative to each other. This causes the headlight cover on the boss 404 to rotate 90°. At this time, the boss 404 on the other support plate 401 contacts the headlight cover that has rotated 90°. The vacuum suction cup 405 on the boss 404 adsorbs the outer wall of the headlight cover. At this time, the vacuum suction cup 405 used to adsorb the inner wall of the headlight cover stops adsorbing the headlight cover. The first motor 4022 rotates in the opposite direction, driving the two support plates 401 to reset, thus completing the rotation of the headlight cover. This reduces manual operation, reduces the workload of workers, and reduces errors caused by manual operation.

[0074] When measuring the outer wall of the headlight cover, the use of the first electric slide 3021, the second electric slide 3022 and the third electric slide 3023, in conjunction with the flipping mechanism 402 and the rotating part 5, can comprehensively measure the inner and outer parts of the headlight cover, which can improve the measurement quality, reduce manual operation and improve measurement efficiency.

[0075] By using the rotating component 5, when inspecting the outer wall of the headlight cover, the second motor 501 drives the first gear 5022 to rotate, which in turn drives the second gear 5023 to rotate. This causes the boss 404 and the bearing 503 to rotate together, and the third electric slide 3023 drives the laser three-dimensional contour sensor 301 to perform a comprehensive measurement of the outer wall of the headlight cover. This is linked with the measurement component 3 to perform a comprehensive measurement of the outer wall of the headlight cover, which can improve the measurement quality of the headlight cover.

[0076] When the headlight cover is pressed onto the vacuum suction cup 405, the spring 9 is compressed, and the vacuum suction cup 405 is pressed into the clearance hole. Through the support of the spring 9, the vacuum suction cup 405 can be pushed to contact the headlight cover. After the headlight cover is removed, the spring 9 can drive the vacuum suction cup 405 to return to its original position, so that the vacuum suction cup 405 protrudes from the boss 404, ensuring that the vacuum suction cup 405 can contact the headlight cover. When the vacuum suction cup 405 is working, it can ensure the adsorption effect of the vacuum suction cup 405 on the headlight cover.

[0077] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
