[0015] A method for using a container size measuring device using laser measurement includes the following steps:

[0016] Step 1: Initial Installation

[0017] Attach the right-angled edge of the right-angled pallet to a corner of the container, and start the vacuum pump in the second mounting slot. The vacuum pump extracts air from the elastic suction cup through the suction pipe, causing the elastic suction cup in the suction hole to adhere to the surface of the container, thereby fixing the right-angled pallet to the corner of one side of the container.

[0018] Step 2: Split

[0019] After the right-angled plate is fixed, release the connection between the box and the right-angled plate, rotate the fastener to disengage it from the slot, pull the protrusion out of the connection slot, and remove the mounting rod from the fastener to complete the separation of the box and the right-angled plate;

[0020] Step 3: Fix the box and prepare the laser reflector assembly

[0021] Move the disassembled box to the other side of the container away from the right-angle pallet, adjust the position of the multiple sets of magnets on one side of the box, and make the magnets fit better on the container surface through the movement of the articulated ball between the spherical groove and the articulated ball seat. Use the magnetic force of the magnets to fix the box to the container. At this time, the photoelectric sensor will detect that the box has been fixed to one side of the container, start the docking motor to drive the second rotating shaft to rotate, so that the rotating bracket rotates, docking the second linear guide with the first linear guide, and start the electric slider to slide on the first and second linear guides, driving the laser reflector to move to the specified position;

[0022] Step 4: Prepare the laser ranging component

[0023] Pulling the handle causes the limit plate to compress the locking spring, and the locking tongue is pulled out of the locking groove. Under the action of the flip cover spring, the flip cover rotates open around the first rotation axis, exposing the laser ranging sensor. The laser ranging sensor emits a laser beam, which passes through the optical lens and is directed to the laser reflector. After being reflected by the laser reflector, it is received by the laser ranging sensor. The control module calculates the distance to the laser reflector based on the time difference between laser emission and reception, thereby completing the measurement of the corresponding dimensions of the container;

[0024] Step 5: Storage

[0025] After the measurement is completed, turn off the laser ranging sensor, push the flip cover to rotate it around the first rotation axis and close it, and the locking tongue is inserted into the locking slot under the action of the locking spring to lock the flip cover. Release the fixation of the right-angle pallet and the box to the container, and reassemble the right-angle pallet and the box for carrying. If you need to measure the dimensions of other parts of the container, repeat steps 1 to 4 to fix the right-angle pallet and the box at different positions of the container for a new round of inspection.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. Through the arrangement of the right-angle pallet and the box body, during assembly, the box body is mounted on the clamping piece on one side of the right-angle pallet through the mounting rod, and then one end of the clamping piece at the bottom of the box body is buckled into the slot, which is convenient for carrying; when in use, the right-angle pallet is first fixed to a corner of the container through the first fixing component, and then the box body is disassembled, moved to the other side of the container and fixed with the second fixing component. This split structure does not require the aid of additional handling equipment. The staff can flexibly move the device to the containers at different locations in the port for size measurement, which solves the problem that the traditional container size detection device is bulky and difficult to move, and improves the convenience of measurement.

[0028] 2. Through the setting of the laser ranging component and the laser reflector component, the second linear guide rail can be docked with the first linear guide rail through the docking motor, and then the electric slider can drive the laser reflector plate to the specified position, and cooperate with the photoelectric sensor to detect the fixed status of the box to ensure the accuracy of the measurement preparation work; the laser beam emitted by the laser ranging sensor is directed to the laser reflector plate in place through the optical lens, and then reflected back to the sensor. The control module calculates the distance based on the time difference between laser emission and reception to realize container size measurement, reduce human interference, and improve measurement accuracy.

[0029] 3. Through the setting of the waterproof shell and the flip cover, the flip cover on the waterproof shell is connected to the rotating hole through the flip spring and can be rotated 90 degrees to open or close. When not in use, it can protect the laser ranging sensor from external environmental influences such as dust and water vapor. The locking groove at one end of the flip cover cooperates with the mechanical locking structure. The locking tongue is inserted into or pulled out of the locking groove to lock and unlock the flip cover. The operation is convenient and the locking is reliable, ensuring the safety and stability of the laser ranging sensor during transportation and when not in use.

[0030] 4. Through the arrangement of the first fixing component and the second fixing component, the right-angled plate and the box body are fixed respectively by elastic suction cups and magnets. The elastic suction cups are connected to the vacuum pump through the suction pipe to adapt to different container surface materials and shapes. The magnets can flexibly adjust the angle through the movement of the articulated ball between the spherical groove and the articulated ball seat to better fit the container surface. This makes the device adaptable to various types of containers. Whether the surface is flat or slightly curved, it can achieve stable fixation, thereby completing the dimensional measurement work and broadening the application range of the device.

[0059] Please refer to Figure 2 、 Figure 6 and Figure 10As shown, a snap-in slot 106 is provided on one side of the box body 102, and a snap-in piece 107 is provided on one side of the right-angled card plate 101. The snap-in piece 107 is detachably passed through the snap-in slot 106 and is provided with a handle 108. A mounting rod 109 is provided in the snap-in slot 106, and the box body 102 is detachably mounted on the snap-in piece 107 through the mounting rod 109; a connecting slot 110 is provided at the bottom of the box body 102, and a protrusion 111 is also provided on one side of the right-angled card plate 101 corresponding to the connecting slot 110. The protrusion 111 can be detachably connected to the connecting slot 110, and a rotatable snap-in piece 112 is provided on one side of the connecting slot 110, and a snap-in slot 113 is provided at the bottom of the protrusion 111. One end of the snap-in piece 112 is detachably buckled in the snap-in slot 113; when the device needs to be carried, the box body 102 is mounted on the snap-in piece 10 on one side of the right-angled card plate 101 through the mounting rod 109. 7, and then buckle one end of the fastener 112 at the bottom of the box body 102 into the slot 113. The overall structure is compact and easy to carry. When in use, first fix the right-angle clamping plate 101 to a corner of the container through the first fixing component, then disassemble the box body 102, rotate the fastener 112 to disengage it from the slot 113, pull the protrusion 111 out of the connecting groove 110, and at the same time remove the mounting rod 109 from the fastener 107 to complete the separation of the box body 102 and the right-angle clamping plate 101. Then move the box body 102 to the other side of the container and fix it with the second fixing component. This split structure does not require the aid of additional handling equipment. The staff can flexibly move the device to the containers at different locations in the port for size measurement, which solves the problem that the traditional container size detection device is bulky and difficult to move, and improves the convenience of measurement.

[0060] A method for using a container size measuring device using laser measurement includes the following steps:

[0061] Step 1: Initial Installation

[0062] The right-angled side of the right-angled plate 101 is attached to a corner of the container. The vacuum pump 506 in the second mounting slot 502 is then activated. The vacuum pump 506 begins to work, extracting air from the elastic suction cup 501 through the suction pipe 507. As the air is extracted, the pressure inside the elastic suction cup 501 decreases. The elastic suction cup 501 in the suction hole 505 is subjected to the external atmospheric pressure and is adsorbed to the surface of the container, thereby fixing the right-angled plate 101 to the corner of the container. This completes the initial installation work.

[0063] Step 2: Split

[0064] After the right-angled plate 101 is fixed, the box 102 and the right-angled plate 101 are separated. The operator rotates the fastener 112 to disengage the fastener 113, then pulls the protrusion 111 out of the connecting groove 110 and removes the mounting rod 109 from the fastener 107, completing the separation of the box 102 and the right-angled plate 101.

[0065] Step 3: Fix the box and prepare the laser reflector assembly

[0066] The disassembled box 102 is moved to the other side of the container away from the right-angled plate 101, and the positions of the multiple groups of magnets 401 on one side of the box 102 are adjusted. The movement of the hinge ball 403 between the ball groove 402 and the hinge ball seat 404 allows the magnet 401 to better fit the surface of the container, and the box 102 is fixed to the container by the magnetic force of the magnet 401. During the fixing process of the box 102, the photoelectric sensor 304 in the first mounting hole 302 will detect that the box 102 has been fixed to one side of the container. When it is detected that the box 102 is fixed in place, the docking motor 308 is started to drive the second rotating shaft 309 to rotate, thereby rotating the rotating bracket 307 to dock the second linear guide 310 with the first linear guide 306. After the docking is completed, the electric slider 303 is started. The electric slider 303 slides on the first linear guide 306 and the second linear guide 310, driving the laser reflector 301 to move to the specified laser reflection position, completing the preparation of the laser reflection assembly.

[0067] Step 4: Prepare the laser ranging component

[0068] Pulling the handle 219 causes the limit plate 217 to compress the locking spring 218, and the locking tongue 214 is withdrawn from the locking groove 213. Under the action of the flip cover spring 208, the flip cover 205 rotates 90 degrees around the first rotation axis 207 to open, exposing the laser ranging sensor 201. The laser ranging sensor 201 starts to emit a laser beam, which passes through the optical lens 212 and is emitted to the laser reflector 301. After being reflected by the laser reflector 301, the laser ranging sensor 201 receives the laser beam. The control module 221 calculates the distance to the laser reflector 301 based on the time difference between laser emission and reception, thereby completing the measurement of the corresponding dimensions of the container.

[0069] Step 5: Storage

[0070] After the measurement is completed, the laser ranging sensor 201 is turned off, and the flip cover 205 is pushed to rotate it around the first rotation axis 207 and close. At this time, the locking tongue 214 is inserted into the locking groove 213 under the action of the locking spring 218 to lock the flip cover 205; then, the fixation of the right-angle clamping plate 101 and the box body 102 to the container is released, and the right-angle clamping plate 101 and the box body 102 are reassembled according to the reverse steps of the assembly for carrying; if it is necessary to measure the dimensions of other parts of the container later, repeat steps one to four, and fix the right-angle clamping plate 101 and the box body 102 at different positions of the container for a new round of inspection to achieve all-round dimension measurement of the container. Example

[0071] Based on the container dimension measurement device and method using laser measurement provided in Example 1 of this application, Example 2 of this application provides a container dimension measurement device and method using laser measurement. This Example 2 is merely a preferred embodiment of Example 1, and the implementation of Example 2 does not affect the independent implementation of Example 1. The second embodiment of the present invention will be further described below.

[0072] Please refer to Figure 14 and Figure 15As shown, the laser reflection assembly also includes an expansion motor 311. A first mounting hole 302 is provided on one side of the first mounting slot 105. A photoelectric sensor 304 is provided in the first mounting hole 302. The photoelectric sensor 304 detects whether the box body 102 is fixed to one side of the container, thereby starting the expansion motor 311 to drive the rotating plate 313 to rotate, so that the laser reflection plate 301 in the first mounting slot 105 rotates and moves to one side of the box body 102. A through slot is provided on one side of the first mounting slot 105, and two sets of rotating seats are provided at one end of the through slot. 312, a rotating plate 313 is rotatably provided between the two sets of rotating seats 312, and an unfolding motor 311 is provided on one side of one set of rotating seats 312, and the main shaft of the unfolding motor 311 is connected to the rotating plate 313; one end of the electric telescopic rod 314 is connected to the rotating plate 313, and the other end is connected to the mounting bracket 315, and an angle adjustment motor 317 is installed in the mounting bracket 315 through four sets of mounting columns 316. A through slot is provided on one side of the mounting bracket 315, and one end of the first connecting rod 318 passes through the through slot and is connected to the main shaft of the angle adjustment motor 317, and the other end The laser reflector 301 is connected to the laser reflector 301, and the laser reflector 301 is rotated by starting the angle adjustment motor 317 to adjust the vertical angle of the laser reflector 301 toward the laser distance sensor 201, and the expansion motor 311 can adjust the horizontal angle of the laser reflector 301 toward the laser distance sensor 201 to a certain extent; an electronic inclinometer 319 is provided on one side of the laser reflector 301, and the electronic inclinometer 319 can be a TLL-90S model; when the box body 102 and the right-angle card plate 101 are not separated, the right-angle card plate 101 is opened. After being fixed at the corner of one side of the container, the vertical angle and horizontal angle of the laser ranging sensor 201 at this time are recorded by the electronic inclinometer 319. When preparing the laser reflection component after disassembly, the laser reflection plate 301 can be adjusted accordingly by the expansion motor 311 and the angle adjustment motor 317 based on the previously recorded vertical angle and horizontal angle of the laser ranging sensor 201, so that the laser reflection plate 301 is perpendicular to the detection laser emitted by the laser ranging sensor 201 to reflect the laser, so as to measure the size of the container.

[0073] Compared with the method in the first embodiment where the electric slider 303 is moved on the first linear guide rail 306 and the second linear guide rail 310 to drive the laser reflector 301 to move from the first mounting groove 105 to the side of the box body 102, the second embodiment opens a through groove on one side of the first mounting groove 105, and sets two sets of rotating seats 312 at one end of the through groove. A rotating plate 313 is rotatably set between the two sets of rotating seats 312, and an expansion motor 311 is set on one side of one set of rotating seats 312 and connected to the rotating plate 313. One end of the electric telescopic rod 314 is connected to the rotating plate 313, and the other end is connected to the mounting plate 313. Mounting bracket 315, an angle adjustment motor 317 is installed in the mounting bracket 315 through four sets of mounting columns 316, one end of the first connecting rod 318 passes through the through slot and is connected to the main shaft of the angle adjustment motor 317, and the other end is connected to the laser reflector 301. The main difference is that the angle of the laser reflector 301 can be adjusted. The laser reflector 301 is driven to rotate by the angle adjustment motor 317 to adjust the vertical angle of the laser reflector 301, while the expansion motor 311 can adjust the horizontal angle of the laser reflector 301 to a certain extent, and on one side of the laser reflector 301 An electronic inclinometer 319 is provided. When the box body 102 and the right-angled plate 101 are not separated, the electronic inclinometer 319 can record the vertical angle and horizontal angle of the laser ranging sensor 201 through the electronic inclinometer 319 after the right-angled plate 101 is fixed to the corner of one side of the container. When the laser reflection assembly is prepared after separation, the angle of the laser reflection plate 301 is adjusted by the expansion motor 311 and the angle adjustment motor 317 according to the previously recorded vertical angle and horizontal angle, so that the laser reflection plate 301 and the laser ranging sensor 201 are aligned. Laser reflection is detected by detecting whether the laser is vertical. Therefore, compared with the method of simply moving the laser reflector 301 from the first mounting slot 105 to the side of the box 102 for laser reflection, this angle adjustment mechanism can improve the accuracy and stability of laser reflection, thereby further improving the accuracy of container size measurement. In actual application scenarios, whether facing a container with a regular shape or a container with a certain degree of deformation or tilt, the device of this embodiment 2 can accurately complete the size measurement task by virtue of its angle adjustment function; the remaining conditions are consistent with those of the embodiment 1, and therefore will not be repeated in this embodiment.
