Description

Technical Field

[0001] This utility model belongs to the field of vehicle lamp housing size detection technology, specifically relating to a lamp housing size detection device. Background Technology

[0002] In modern manufacturing, the lamp housing is an important component of vehicle lights. Its dimensional accuracy directly affects the assembly quality, structural stability, and safety of vehicle lights. Dimensional deviations in the lamp housing can lead to problems such as difficulty in component assembly, reduced sealing performance, and optical distortion, and may even cause safety hazards. Therefore, efficient and accurate dimensional inspection of the lamp housing is an indispensable key link in the production process.

[0003] Currently, with the continuous improvement of automation and intelligence in the manufacturing industry, enterprises have increasingly higher requirements for production efficiency and product quality. The limitations of traditional manual inspection methods are becoming more and more prominent. In order to improve inspection efficiency and accuracy, semi-automatic inspection equipment has begun to be introduced. That is, the lamp housing is placed on the inspection station by a person, and then the size is measured by mechanical structure or optical system. Although this method improves the inspection accuracy to a certain extent, it still requires manual participation in feeding. Not only is the labor intensity not effectively reduced, but the speed and stability of manual feeding also limit the further improvement of overall inspection efficiency, which greatly reduces the inspection efficiency.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0027] This utility model provides, for example Figure 1-5 The lamp housing size detection device shown includes:

[0028] Frame 1, with side plates 2 connected to both sides of the frame 1;

[0029] A movable tray 3 is located within a frame 1. Two sets of guide rails 4 are connected within the frame 1. A slider is slidably connected within each guide rail 4 and is connected to the movable tray 3. A Y-axis servo lead screw linear module 7 is located within the frame 1 and between the two sets of guide rails 4. A movable top plate 5 is located on the top of the movable tray 3. A detection sensor 6 for detecting the size of the lamp housing is located on the movable top plate 5. Various models of the detection sensor 6 can be selected, such as laser displacement sensors, like the OSM40 laser rangefinder from Yike, or measuring gratings, like the SUNS series size detection gratings. The specific selection depends on factors such as the material, shape complexity, and detection accuracy requirements of the lamp housing.

[0030] The Y-axis moving slide of the Y-axis servo lead screw linear module 7 is connected to the moving tray 3, and the top of the frame 1 is equipped with a servo motor 8.

[0031] Two sets of lead screws 18 are rotatably connected inside the frame 1, and the two ends of the movable top plate 5 are connected to the lead screws 18 through lead screw nuts 24. A transmission wheel 20 is connected to the top of the lead screw 18. Several guide rods 9 are connected inside the frame 1, and the two ends of the movable top plate 5 are slidably sleeved on the guide rods 9. The guide rods 9 can restrict the movement direction of the movable top plate 5, so that it can only move vertically up and down along the guide rods 9, and prevent the movable top plate 5 from deviating when it moves.

[0032] The servo motor 8 is connected to the lead screw 18 via a transmission belt 21 and a transmission wheel 20. Three tensioning wheels 27 are installed on the top of the frame 1. The tensioning wheels 27 are in contact with the transmission belt 21 to keep the transmission belt 21 taut and ensure that the transmission belt 21 does not slip. This allows the two lead screws 18 to rotate stably. Two sets of cable carriers 10 are provided on the top of the frame 1. The cable carriers 10 can store various cables inside the equipment, such as sensor signal lines and motor power lines. They can extend, retract, or bend synchronously with the movement of each component, preventing the cables from being pulled, tangled, or worn due to messiness, and ensuring smooth and stable signal and power transmission.

[0033] The front end of the frame 1 is connected to a bracket 11 and a display 12 is mounted on the bracket 11. The top two ends of the movable tray 3 are provided with fixed cylinders 22 and the piston rods of the fixed cylinders 22 are connected to positioning clamps 25.

[0034] The frame 1 is connected to a mounting bracket 13 and a controller 14 is mounted on the mounting bracket 13. The front end of the frame 1 is provided with two sets of emergency stop switches 26. When an emergency occurs, the two sets of emergency stop switches 26 can allow the operator to quickly trigger the stop command within the shortest distance.

[0035] The bottom of the frame 1 is connected to several feet 15. In some uneven ground, the height of each foot 15 can be adjusted individually to keep the equipment stable and avoid instability caused by the tilt of the ground. The bottom of the frame 1 is also rotatably connected to several casters 16. The casters 16 make it easier to change the position of the equipment without the need for large lifting equipment. Operators can easily push the equipment to move.

[0036] The frame 1 is equipped with an inner grating protective cover 17, and the movable tray 3 is equipped with two sets of pneumatic multi-connectors 23. The pneumatic multi-connectors 23 are installed here to centrally connect the various pneumatic pipelines required by the tooling, avoiding the mess caused by the dispersed arrangement of pipelines. The inner grating protective cover 17 inside the frame 1 is always in working condition. The grating it emits forms an invisible protective barrier. When the operator's hand, arm or other body parts accidentally enter the dangerous area inside the frame 1, the grating will immediately detect the obstruction signal and quickly transmit the signal to the equipment controller 14. After receiving the signal, the controller 14 will issue an instruction in a very short time to stop the moving parts of the equipment from running, so as to avoid the moving parts causing squeezing, collision or other injuries to the human body.

[0037] The lamp housing size inspection equipment allows the operator to place the lamp housing to be inspected stably on the moving tray 3, ensuring that the lamp housing is in the correct position. Then, the operator operates the equipment through the controller 14 at the front end of the frame 1, and completes various basic settings according to the type of lamp housing and inspection requirements, in order to prepare for the inspection work.

[0038] When the device is started by the controller 14, the fixing cylinder 22 is activated. The piston rod of the fixing cylinder 22 pushes the positioning clamp 25 to move closer to the lamp housing, clamping and fixing the lamp housing to prevent it from shifting during subsequent movement and affecting the detection results. After the lamp housing is fixed, the Y-axis servo lead screw linear module 7 starts to work. Its internal servo motor drives the lead screw to rotate, which in turn drives the Y-axis moving slide to move along the lead screw direction. Since the moving tray 3 is connected to the Y-axis moving slide and the bottom of the moving tray 3 is connected to the slider on the guide slide rail 4, the moving tray 3 will slide smoothly along the Y-axis direction together with the Y-axis moving slide. The guide slide rail 4 plays a precise guiding role for the moving tray 3, limiting its sway in other directions and ensuring that the lamp housing can be accurately transported to the detection area directly below the detection sensor 6.

[0039] When the lamp housing reaches the detection area, the servo motor 8 at the top of the frame 1 receives the signal and starts. The servo motor 8 drives the transmission belt 21 to move, which in turn drives the two transmission wheels 20 to rotate. The transmission wheels 20 drive the lead screw 18 to rotate, and the lead screw 18 drives the movable top plate 5 to move downwards via the lead screw nut 24. Several guide rods 9 pass through the movable top plate 5 and are fixed to the frame 1, strictly limiting the movement direction of the movable top plate 5 so that it can only move vertically up and down along the guide rods 9. In this way, the detection sensor 6 installed on the movable top plate 5 also moves up and down accordingly. The vertical distance between the sensor and the lamp housing is adjusted, and the detection sensor 6 starts working after reaching the appropriate position. It scans or senses various dimensions of the lamp housing below. The detection sensor 6 converts the captured lamp housing size information into electrical signals and transmits the signals to the device controller 14 through internal circuitry. The controller 14 analyzes and processes the received signals and converts them into identifiable size information. This information is then sent to the display 12 at the front of the rack 1 and presented in a clear image or text format. The operator can clearly understand whether the lamp housing size meets the standard by observing the display 12.

[0040] After a test is completed, the controller 14 issues a command, and the servo motor 8 drives the moving top plate 5 and the detection sensor 6 to move upward and return to the initial position. At the same time, the Y-axis servo lead screw linear module 7 operates in reverse, driving the moving tray 3 to slide back to the initial position along the guide rail 4. At this time, the operator can remove the tested lamp housing and place the new lamp housing to be tested on the moving tray 3 to prepare for the next test. During the entire operation of the equipment, the cable chain 10 collects various cables inside the equipment, such as the sensor signal lines and the motor power lines. It extends, retracts, or bends synchronously with the movement of each component, avoiding the cables from being pulled, tangled, or worn due to messiness, and ensuring smooth and stable signal and power transmission.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
