Description

Technical Field

[0001] This invention relates to the field of measuring device technology, specifically to a non-stop dynamic measuring device for cargo and its measuring method. Background Technology

[0002] Currently, for handling large palletized goods, we mainly rely on traditional weighing devices and volume measurement devices. These devices are usually static measurements, requiring palletized goods to be forked onto the platform scale one by one to obtain their weight in a static manner. Similarly, volume measurement also needs to be done through separate static volume measurement devices, such as volumetric volume measuring instruments or volume measuring instruments. The collected weight and volume data are then integrated and then incorporated into the customer's system.

[0003] This process is clearly inefficient. Each measurement requires using a forklift to move the goods from the stacking area to the measurement area of ​​the platform scale. After the test is completed, the goods are moved back to their original location or loaded onto a truck. This series of steps is not only time-consuming but also increases operating costs. In order to improve efficiency, we urgently need to optimize the existing weighing and volume measurement process. Summary of the Invention

[0029] The present invention also provides a measurement method for a cargo non-stop dynamic measurement device, the method comprising the following steps:

[0030] The weight information of the goods is obtained by the forklift scale on the forklift and transmitted to the on-board flatbed and / or control console;

[0031] When the forklift travels to the measurement area, it captures the barcode on the goods through the dynamic barcode scanning component and creates a measurement task for the goods. After creating the measurement task for the goods, it collects the weight information of the corresponding goods through the on-board tablet and / or console, and captures the volume information of the corresponding goods through the volume measurement component and transmits it to the console.

[0032] The collected volume, weight, and barcode information of the corresponding goods are exchanged between the vehicle-mounted tablet and the control console;

[0033] The console and / or vehicle-mounted tablet will upload the weight, volume, and barcode information of the corresponding goods.

[0034] By employing the above technical solution, the present invention provides a non-stop dynamic measurement device for cargo, which has at least the following beneficial effects:

[0035] 1. This invention uses dynamic measurement technology, which involves installing a forklift scale on the front teeth of a forklift. When the forklift picks up the goods and moves to the goods placement area, the forklift scale automatically acquires the weight of the goods, the dynamic barcode scanning component automatically captures the barcode on the goods, and the volume measurement component automatically captures the volume information of the goods. This allows the weight and volume of the goods to be measured during transportation, without the need for static measurement by stopping the vehicle. This not only reduces the frequency of forklift use but also greatly improves the efficiency of measurement.

[0036] 2. In this invention, the first motor starts and drives the first threaded rod to rotate, so that the moving frame moves back and forth inside the fixed box. As the moving frame moves, the barcode scanning camera fixed on it also moves back and forth accordingly, so that the barcode scanning camera can automatically capture the barcode on the goods. This realizes the automatic tracking and dynamic capture function of the barcode scanning camera, improving the efficiency and accuracy of barcode scanning.

[0037] 3. In this invention, during the forward and backward movement of the movable frame, the fixed frame moves synchronously. During this process, the slide bar slides back and forth inside the rotating sleeve to ensure the stability of the structure. At the same time, the limiting rod slides back and forth in the limiting groove inside the rotating sleeve. The rotating sleeve plays a guiding and limiting role to prevent deviation or shaking during the movement.

[0038] 4. In this invention, when the barcode scanner needs adaptive adjustment, the second motor starts running and drives the slide bar to rotate. Since the limit rod is connected to the slide bar, the rotation of the limit rod will cause the rotating sleeve to rotate on the fixed frame. The rotational force is transmitted to the first bevel gear through the second bevel gear. Due to the meshing relationship between the two, the first bevel gear will also rotate. The rotation of the first bevel gear will further drive the second threaded rod connected to it to rotate. As the second threaded rod rotates, the sliding block moves up and down in the moving frame. Since the sliding block is connected to the barcode scanner, the barcode scanner will also move up and down accordingly, so that the position of the barcode scanner can be flexibly adjusted from multiple angles to meet the scanning requirements of goods at different heights, and avoid the situation where the barcode on the goods cannot be captured due to the different heights when the forklift lifts the goods.

[0039] 5. The third motor starts, causing the third bevel gear to rotate. This rotation further drives the fourth bevel gear, which in turn rotates the ball screw within the sleeve. The ball screw engages with the ball nut inside the sleeve, converting rotational motion into linear motion, allowing the sleeve to move up and down along the axis of the ball screw. Simultaneously, the telescopic rod extends and retracts, and the sleeve's vertical movement drives the volume measuring camera on the volume measuring assembly to move up and down. This allows the volume measuring camera to adjust its distance from the goods according to actual needs, enabling flexible adjustment of its posture based on the actual height of the goods. Whether dealing with low or tall goods, it can easily handle them, ensuring accuracy and efficiency during measurement and enhancing flexibility and practicality.

[0040] 6. The fourth motor starts, causing the small gear to rotate. The rotation of the small gear drives the large gear to rotate. The rotation of the large gear, through the connection of the telescopic rod, is converted into the rotational motion of the volume measuring component. The telescopic rod not only serves as a connection and support but also ensures smooth up-and-down movement without interfering with the height adjustment of the volume measuring component. As the volume measuring component rotates, the volume measuring camera also rotates, thus enabling the adjustment of its angle. The volume measuring camera can flexibly adjust its shooting angle to adapt to different goods or different measurement needs, avoiding errors in the volume of goods caused by forklift deviation.

[0041] 7. When the fifth motor starts, the drive gear begins to rotate. Since the teeth of the drive gear mesh with the teeth of one of the racks, the rotation of the drive gear will cause the base to slide along the length of the support rod. The auxiliary gear ensures the stability and straightness of the base during the sliding process, and drives the volume measuring camera to move. Since different goods have different shapes and sizes, and some goods even have irregular shapes, the position of each volume measuring camera can be adjusted as needed to ensure that the volume measuring camera can capture the best view of the goods, reduce measurement errors caused by improper viewing angles or blind spots, and thus improve the accuracy of volume measurement.

[0042] 8. When the bidirectional threaded rod rotates, the opposite thread directions on both sides allow the nuts on both sides to move towards or away from each other. The connecting column moves with the nuts, and the rotating rod is pushed or pulled by the support rod. The stabilizing wheel will adjust its position with the rotation of the rotating rod, ensuring that the groove of the stabilizing wheel is always in rolling contact with the outer surface of the limit strip. This enhances the stability of the volume measurement camera when it moves and also facilitates the installation and disassembly of the base. Attached Figure Description

[0061] 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, and 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.

[0062] Example 1:

[0063] Please see Figure 1 and Figure 2 A non-stop dynamic measurement device for goods includes a stand 1 and a forklift scale. The forklift scale is installed on the front teeth of the forklift and connected to the forklift's onboard flatbed. The forklift scale can move with the forklift and measure the weight of the goods in real time.

[0064] A dynamic barcode scanning component 2 is fixedly connected to the upright frame 1. The dynamic barcode scanning component 2 is used to dynamically capture the barcode on the goods, which greatly improves the efficiency and accuracy of barcode scanning. A connector 3 is fixedly connected to the top of the upright frame 1. A posture adjustment component 4 is fixedly connected to one end of the connector 3. A volume measurement component 5 is connected to the bottom of the posture adjustment component 4. The posture adjustment component 4 is used to drive the volume measurement component 5 to adjust at multiple angles. The volume measurement component 5 adaptively captures the volume information of the goods.

[0065] A non-stop dynamic measurement device for goods also includes a display screen 6, an alarm device 7, and a control console 8. The display screen 6 and the alarm device 7 are fixedly connected to the stand 1. The display screen 6 is used to display the goods measurement data and scanning results in real time, so that the operator can intuitively understand the information of the goods. The alarm device 7 can issue an alarm when abnormal situations occur to ensure the safe and stable operation of the device. Abnormal situations include measurement abnormalities or data abnormalities.

[0066] The alarm device 7 can be one of the following: an electronic buzzer, an alarm light, an LED display screen, and a vibrator, or a combination of these devices. When an abnormality occurs during the measurement or scanning process, such as scanning failure, goods size exceeding the preset range, or equipment failure, the alarm device 7 will immediately issue an alarm.

[0067] The control console 8 is connected to the dynamic barcode scanning component 2, the attitude adjustment component 4, the volume measurement component 5, the display screen 6, the alarm device 7, and the forklift scale. The dynamic barcode scanning component 2, the attitude adjustment component 4, the volume measurement component 5, the display screen 6, and the alarm device 7 can be connected to the control console 8 via wired connection, while the forklift scale can be connected to the control console 8 via wireless connection. Specifically, the forklift scale is connected to the forklift's onboard flatbed, and the onboard flatbed and control console 8 exchange and transmit signals. The signals exchanged and transmitted include, but are not limited to, the weight data, volume data, and barcode scanning data of the goods.

[0068] The control console 8 adopts an integrated design, combining an industrial touchscreen, PC host, mouse, and keyboard. It features data processing and display capabilities, receiving measurement data from the forklift scale, dynamic barcode scanner 2, and volume measurement module 5. After internal processing, the data is displayed in real-time on the screen 6, or transmitted to a vehicle-mounted tablet. This allows operators to intuitively understand the measurement data and barcode scanning results of the goods, enabling timely decision-making and adjustments. Furthermore, the control console 8 can judge the measurement data according to preset rules and thresholds. When abnormalities or out-of-range conditions occur, an alarm is triggered via the alarm device 7 to alert the operator.

[0069] The console 8 and the vehicle-mounted tablet also have the ability to communicate with other systems or devices. They can connect with the enterprise's management system, database, etc., to achieve data sharing and exchange. This allows the measurement data of goods to be easily imported into the enterprise's management system for subsequent statistical analysis, inventory management, and other operations, thereby improving the enterprise's management level and efficiency.

[0070] This invention employs dynamic measurement technology, installing a forklift scale on the front teeth of a forklift. When the forklift picks up goods and travels to the goods placement area, the forklift scale automatically acquires the weight of the goods, the dynamic barcode scanning component 2 automatically captures the barcode on the goods, and the volume measurement component 5 automatically captures the volume information of the goods. This allows the weight and volume of the goods to be measured during transportation, without the need for static measurement by stopping the vehicle. This not only reduces the frequency of forklift use but also greatly improves measurement efficiency.

[0071] Specifically, in this embodiment, the measurement process of the non-stop dynamic measurement device for goods can be as follows:

[0072] The weight information of the goods is obtained by the forklift scale on the forklift and transmitted to the on-board flatbed and / or control console 8;

[0073] When the forklift travels to the measurement area, the barcode on the goods is captured by the dynamic barcode scanning component 2 and a measurement task for the goods is created. After the measurement task for the goods is created, the weight information of the corresponding goods is collected by the on-board tablet and / or the console 8, and the volume information of the corresponding goods is captured by the volume measurement component 5 and transmitted to the console 8.

[0074] The collected volume, weight, and barcode information of the corresponding goods are exchanged between the vehicle-mounted tablet and the control console 8.

[0075] The console 8 and / or the vehicle-mounted tablet will upload the weight, volume, and barcode information of the corresponding goods.

[0076] Example 2:

[0077] like Figures 3-7As shown, this embodiment is based on embodiment one, but differs from embodiment one in that the dynamic scanning component 2 includes a fixed box 201, a movable frame 202 is slidably connected inside the fixed box 201, and a threaded sleeve 203 is embedded on the movable frame 202.

[0078] The first motor 204 is fixedly connected inside the fixed box 201. The output end of the first motor 204 is fixedly connected to the first threaded rod 205. One end of the first threaded rod 205 passes through the threaded sleeve 203 and is rotatably connected to the fixed box 201. A barcode scanner 206 is connected to the front of the fixed box 201.

[0079] The first motor 204 starts and drives the first threaded rod 205 to rotate, so that the moving frame 202 moves back and forth inside the fixed box 201. As the moving frame 202 moves, the barcode scanning camera 206 fixed on it also moves back and forth accordingly, so that the barcode scanning camera 206 can automatically capture the barcode on the goods. This realizes the automatic tracking and dynamic capture function of the barcode scanning camera 206, improving the efficiency and accuracy of barcode scanning.

[0080] The movable frame 202 is rotatably connected to a second threaded rod 207. The outer surface of the second threaded rod 207 is threaded with a sliding block 208. The sliding block 208 is slidably connected inside the movable frame 202. The barcode camera 206 is fixedly connected to the front of the sliding block 208.

[0081] A fixed frame 209 is fixedly connected to the bottom of the movable frame 202. One end of the second threaded rod 207 passes through and extends into the interior of the fixed frame 209. A first bevel gear 210 is fixedly sleeved on one end of the second threaded rod 207. A rotating sleeve 211 is rotatably connected inside the fixed frame 209. A second bevel gear 212 is fixedly sleeved on the outer surface of the rotating sleeve 211. The teeth of the second bevel gear 212 mesh with the teeth of the first bevel gear 210. A drive module is connected inside the fixed box 201. The drive module is used to drive the rotating sleeve 211 to rotate.

[0082] Example 3:

[0083] like Figures 5-7 As shown, this embodiment is based on embodiment two, but differs from embodiment two in that the drive module includes a second motor 213, which is fixedly connected inside the fixed box 201. The output end of the second motor 213 is fixedly connected to a slide rod 214, and the outer surface of the slide rod 214 is slidably connected to the inner wall of the rotating sleeve 211.

[0084] Limiting rods 215 are fixedly connected to both sides of the outer surface of the slide rod 214, and limiting grooves 216 are opened on both sides of the inner wall of the rotating sleeve 211, with the limiting rods 215 located inside the limiting grooves 216.

[0085] During the forward and backward movement of the movable frame 202, the fixed frame 209 will move synchronously. During this process, the slide bar 214 slides back and forth inside the rotating sleeve 211 to ensure the stability of the structure. At the same time, the limiting rod 215 slides back and forth in the limiting groove 216 inside the rotating sleeve 211. The rotating sleeve 211 plays a guiding and limiting role to prevent deviation or shaking during the movement.

[0086] When the barcode scanner 206 needs adaptive adjustment, the second motor 213 starts running, driving the slide bar 214 to rotate. Since the limit rod 215 is connected to the slide bar 214, the rotation of the limit rod 215 will drive the rotating sleeve 211 to rotate on the fixed frame 209. The rotational force is transmitted to the first bevel gear 210 through the second bevel gear 212. Due to the meshing relationship between the two, the first bevel gear 210 will also rotate. The rotation of the first bevel gear 210 further drives the second threaded rod 207 connected to it to rotate. As the second threaded rod 207 rotates, the sliding block 208 moves up and down in the moving frame 202. Since the sliding block 208 is connected to the barcode scanner 206, the barcode scanner 206 will also move up and down accordingly, so that the position of the barcode scanner 206 can be flexibly adjusted at multiple angles to meet the barcode scanning needs of goods at different heights, and to avoid the situation where the barcode on the goods cannot be captured due to uneven height when the forklift lifts the goods.

[0087] During the non-stop dynamic scanning of goods, the height, position and angle of the goods are different, and it is difficult for the fixed-position barcode camera 206 to adapt to these changes. By dynamically and adaptively adjusting the position of the barcode camera 206, it can be ensured that the barcode camera 206 is always aligned with the barcode on the goods, thereby accurately capturing barcode information, reducing the occurrence of scanning failures or repeated scanning, and greatly improving the accuracy and efficiency of barcode scanning.

[0088] like Figure 3 As shown, first dustproof folding cloths 217 are fixedly connected to both the left and right sides of the movable frame 202 and the fixed frame 209, with one side of the first dustproof folding cloth 217 fixedly connected to the inner wall of the fixed box 201; second dustproof folding cloths 218 are fixedly connected to both the upper and lower sides of the sliding block 208, with one end of the second dustproof folding cloth 218 fixedly connected to the inner wall of the movable frame 202. The first dustproof folding cloths 217 and the second dustproof folding cloths 218 have a certain degree of flexibility, and can naturally extend or retract as the movable frame 202, the fixed frame 209, and the sliding block 208 move, protecting the internal structure of the fixed box 201 from dust pollution caused by forklift movement.

[0089] Example 4:

[0090] like Figures 8-10 As shown, this embodiment is based on embodiment three, but differs from embodiment three in that...

[0091] The attitude adjustment component 4 includes a mounting plate 401, which is fixedly connected to the connector 3. The bottom of the mounting plate 401 is fixedly connected to a mounting bracket 402 and a third motor 403. The output end of the third motor 403 is fixedly fitted with a third bevel gear 404.

[0092] A rotating sleeve 405 is rotatably connected to the middle of the mounting bracket 402. A ball screw 406 is rotatably connected inside the rotating sleeve 405. A fourth bevel gear 407 is fixedly sleeved on the top of the ball screw 406. The teeth of the fourth bevel gear 407 mesh with the teeth of the third bevel gear 404.

[0093] A sleeve 408 is fitted on the outer surface of the ball screw 406. A volume measuring component 5 is connected to the bottom of the sleeve 408. The volume measuring component 5 includes multiple volume measuring cameras 508. A ball nut is fixedly connected inside the sleeve 408. The ball nut is threaded onto the outer surface of the ball screw 406. A support frame 409 is slidably fitted on the outer surface of the sleeve 408. The top of the support frame 409 is fixedly connected to the rotating sleeve 405.

[0094] The third motor 403 starts, causing the third bevel gear 404 to rotate. The rotation of the third bevel gear 404 further drives the fourth bevel gear 407 to rotate. As the fourth bevel gear 407 rotates, the ball screw 406 also begins to rotate within the rotating sleeve 405. The ball screw 406 engages with the ball nut inside the sleeve 408, converting the rotational motion into linear motion, allowing the sleeve 408 to move up and down along the axis of the ball screw 406. At this time, the telescopic rod 412 extends and retracts, and the up-and-down movement of the sleeve 408 drives the volume measuring camera 508 on the volume measuring assembly 5 to move up and down. In this way, the volume measuring camera 508 can adjust the distance between itself and the goods according to actual needs, allowing it to flexibly adjust its posture based on the actual height of the goods. Whether dealing with low or tall goods, it can easily handle them, ensuring accuracy and efficiency during measurement, and enhancing flexibility and practicality.

[0095] In practical applications, goods of different heights require different measurement angles and distances. By adjusting the height of the volume measuring camera 508, it can be ensured that the volume measuring camera 508 is always in the best shooting position, thereby obtaining more accurate volume data. This design not only improves the accuracy of measurement, but also reduces the difficulty of operation, making the whole measurement process more convenient.

[0096] A large gear 413 is fixedly mounted on the outer surface of the rotating sleeve 405. Multiple small gears 411 are circumferentially rotatably connected to the bottom of the mounting bracket 402. The teeth of the small gears 411 mesh with the teeth of the large gear 413. A fourth motor 410 is fixedly connected inside the mounting bracket 402. The output end of the fourth motor 410 is fixedly connected to one of the small gears 411. Telescopic rods 412 are fixedly connected to both sides of the bottom of the large gear 413. The bottom of the telescopic rods 412 is connected to the volume measuring component 5.

[0097] The fourth motor 410 starts, causing the small gear 411 to rotate. The rotation of the small gear 411 drives the large gear 413 to rotate. The rotation of the large gear 413 is converted into the rotation of the volume measuring component 5 through the connection of the telescopic rod 412. The telescopic rod 412 not only plays a connecting and supporting role, but also ensures the smooth up and down movement, and does not interfere with the height adjustment of the volume measuring component 5. As the volume measuring component 5 rotates, the volume measuring camera 508 also rotates, thereby realizing the adjustment of its angle. The volume measuring camera 508 can flexibly adjust its shooting angle to adapt to different goods or different measurement needs, avoiding errors in the volume of goods caused by forklift deviation.

[0098] The volume measuring camera 508 can flexibly adjust its shooting angle, which is of great significance in practical applications. By adjusting the shooting angle of the volume measuring camera 508, it can be ensured that the volume measuring camera 508 can capture the complete outline of the goods, thereby obtaining accurate volume data. In addition, when the forklift deviates during transportation, adjusting the position of the volume measuring camera 508 can effectively avoid the measurement error caused by this, and improve the reliability of the data.

[0099] Example 5:

[0100] like Figures 11-14 As shown, this embodiment is based on Embodiment 4, but differs from Embodiment 4 in that...

[0101] The volume measurement component 5 includes a base plate 501. Multiple support rods 502 are fixedly connected to the outer periphery of the base plate 501 at equal intervals. A rack 503 is embedded on both sides of the support rod 502. A base 504 is slidably sleeved on the bottom of the support rod 502. A fifth motor 505 is fixedly connected to one side of the base 504. A drive gear 506 is fixedly sleeved on the output end of the fifth motor 505. The teeth of the drive gear 506 mesh with the teeth of one of the racks 503. An auxiliary gear 507 is rotatably connected to the other side of the base 504. The teeth of the auxiliary gear 507 mesh with the teeth of another rack 503.

[0102] The volume measurement camera 508 is connected to the bottom of the base 504; in this embodiment, five volume measurement cameras 508 can be specifically set; the volume measurement camera adopts 3D structured light technology, which projects structured light onto the surface of the goods, the volume measurement camera receives the structured light reflected from the surface of the goods, the color camera dynamically acquires the image information of the object, and calculates the volume and size of the goods through the corresponding dynamic algorithm.

[0103] When the fifth motor 505 starts, the drive gear 506 begins to rotate. Since the teeth of the drive gear 506 mesh with the teeth of one of the racks 503, the rotation of the drive gear 506 will cause the base 504 to slide along the length of the support rod 502. The auxiliary gear 507 ensures the stability and straightness of the base 504 during the sliding process, and drives the volume measuring camera 508 to move. Since different goods have different shapes and sizes, and some goods even have irregular shapes, the position of each volume measuring camera 508 can be adjusted as needed to ensure that the volume measuring camera 508 can capture the best view of the goods, reduce measurement errors caused by improper viewing angles or blind spots, and thus improve the accuracy of volume measurement.

[0104] Example 6:

[0105] like Figure 15 and Figure 16 As shown, this embodiment is based on embodiment five. The difference from embodiment five is that an adjustable stabilizer 509 is connected to the top of the base 504, and a rectangular groove is provided at the bottom of the support rod 502. Limiting strips 510 are fixedly connected to both sides of the inner wall of the rectangular groove.

[0106] The adjustable stabilizer 509 includes a bidirectional threaded rod 5091, which is rotatably connected to the inside of the base 504. Nuts 5092 are threaded on both sides of the outer surface of the bidirectional threaded rod 5091. Connecting posts 5093 are fixedly connected to the outer surface of the nuts 5092. Two support rods 5094 are rotatably connected to the top and bottom of the connecting posts 5093 respectively.

[0107] Support sleeves 5095 are rotatably connected to both sides of the inner bottom wall of the base 504. Two rotating rods 5096 are rotatably connected to the upper and lower sides of the outer surface of the support sleeve 5095. One end of the support rod 5094 is rotatably connected to the corresponding rotating rod 5096. A stabilizing wheel 5097 is rotatably connected between the two corresponding rotating rods 5096. The groove of the stabilizing wheel 5097 is rolled on the outer surface of the limiting strip 510.

[0108] The rotating rod 5096 has a clearance hole in the middle, and the outer diameter of the bidirectional threaded rod 5091 is smaller than the inner diameter of the clearance hole.

[0109] In some embodiments, a locking element is also installed on the bidirectional threaded rod 5091. The locking element is a locking pin, a locking nut, or other locking structure. The locking element ensures that after the position of the stabilizing wheel 5097 is adjusted, the stabilizing wheel 5097 can be fixed in a specific position to prevent the bidirectional threaded rod 5091 from rotating accidentally due to vibration, gravity, or other external factors, thus ensuring the stability of the stabilizing wheel 5097.

[0110] When the bidirectional threaded rod 5091 rotates, the opposite thread directions on both sides of the bidirectional threaded rod 5091 allow the nuts 5092 on both sides to move towards or away from each other. The connecting column 5093 moves with the movement of the nuts 5092. The support rod 5094 pushes or pulls the rotating rod 5096. The stabilizing wheel 5097 adjusts its position with the rotation of the rotating rod 5096, ensuring that the groove of the stabilizing wheel 5097 is always in rolling contact with the outer surface of the limiting strip 510. This enhances the stability of the volume measurement camera 508 when it moves, and at the same time, facilitates the installation and disassembly of the base 504.

[0111] Working principle: The forklift scale is installed on the front teeth of the forklift. When the forklift picks up the goods and moves to the goods placement area, the forklift scale can move with the forklift and measure the weight of the goods in real time.

[0112] The first motor 204 starts and drives the first threaded rod 205 to rotate, so that the moving frame 202 moves back and forth inside the fixed box 201. As the moving frame 202 moves, the barcode camera 206 fixed on it also moves back and forth accordingly.

[0113] During the forward and backward movement of the movable frame 202, the fixed frame 209 will move synchronously. During this process, the slide bar 214 slides back and forth inside the rotating sleeve 211 to ensure the stability of the structure. At the same time, the limiting bar 215 slides back and forth in the limiting groove 216 inside the rotating sleeve 211.

[0114] When the second motor 213 starts running, it drives the slide bar 214 to rotate. Since the limiting rod 215 is connected to the slide bar 214, the rotation of the limiting rod 215 will drive the rotating sleeve 211 to rotate on the fixed frame 209. The rotational force is transmitted to the first bevel gear 210 through the second bevel gear 212. Due to the meshing relationship between the two, the first bevel gear 210 will also rotate. The rotation of the first bevel gear 210 will further drive the second threaded rod 207 connected to it to rotate. As the second threaded rod 207 rotates, the sliding block 208 moves up and down in the moving frame 202. Since the sliding block 208 is connected to the barcode scanner 206, the barcode scanner 206 will also move up and down accordingly, so that the position of the barcode scanner 206 can be flexibly adjusted at multiple angles. The barcode scanner 206 can automatically track and capture the barcode of the goods.

[0115] The third motor 403 starts, causing the third bevel gear 404 to rotate. The rotation of the third bevel gear 404 further drives the fourth bevel gear 407 to rotate. As the fourth bevel gear 407 rotates, the ball screw 406 also begins to rotate within the rotating sleeve 405. The ball screw 406 engages with the ball nut inside the sleeve 408, converting the rotational motion into linear motion, allowing the sleeve 408 to move up and down along the axis of the ball screw 406. At this time, the telescopic rod 412 extends and retracts, and the up and down movement of the sleeve 408 drives the up and down movement of the volume measuring camera 508 on the volume measuring assembly 5.

[0116] The fourth motor 410 starts, causing the small gear 411 to start rotating. The rotation of the small gear 411 drives the large gear 413 to rotate. The rotation of the large gear 413 is converted into the rotation of the volume measuring component 5 through the connection of the telescopic rod 412. The telescopic rod 412 not only plays the role of connection and support, but also ensures the smooth up and down movement, and will not interfere with the height adjustment of the volume measuring component 5. As the volume measuring component 5 rotates, the volume measuring camera 508 also rotates, thereby realizing the adjustment of its angle. The volume measuring camera 508 can flexibly adjust its shooting angle to adapt to different goods or different measurement needs.

[0117] When the fifth motor 505 starts, the drive gear 506 begins to rotate. Since the teeth of the drive gear 506 mesh with the teeth of one of the racks 503, the rotation of the drive gear 506 will drive the base 504 to slide along the length of the support rod 502. The auxiliary gear 507 ensures the stability and straightness of the base 504 during the sliding process, and drives the volume measuring camera 508 to move. Since different goods have different shapes and sizes, and some goods even have irregular shapes, the position of each volume measuring camera 508 can be adjusted as needed to ensure that the volume measuring camera 508 can capture the best view of the goods and reduce measurement errors caused by improper viewing angles or blind spots.

[0118] When the bidirectional threaded rod 5091 rotates, the nuts 5092 on both sides can move towards or away from each other because the threads on both sides of the bidirectional threaded rod 5091 are in opposite directions. The connecting column 5093 moves with the movement of the nuts 5092. The rotating rod 5096 is pushed or pulled by the support rod 5094. Since the bottom of the rotating rod 5096 is rotatably connected to the base 504, the stabilizing wheel 5097 adjusts its position with the rotation of the rotating rod 5096, ensuring that the groove of the stabilizing wheel 5097 is always in rolling contact with the outer surface of the limiting strip 510, which enhances the stability of the volume measurement camera 508 when it moves.

[0119] This invention enables the measurement of weight and volume of goods during transportation without requiring static measurement by stopping the vehicle. This not only reduces the frequency of forklift use but also greatly improves measurement efficiency.

[0120] It should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
