[0018] In order to further explain the technical solution of the present utility model, the present utility model is described in detail below through specific embodiments.

[0019] The fully automatic mobile weighing device disclosed in this embodiment includes a self-propelled vehicle 1 and a weighing system 2 mounted on the self-propelled vehicle 1. Figure 1 , Figure 2 and Figure 3 As shown, the self-moving vehicle 1 is a basic carrier, and the self-moving vehicle of the prior art structure can be adopted or referred to, such as a transfer AGV, which can usually include an intelligent mobile control system, a dual-drive mobile chassis 11, and a laser obstacle avoidance and collision avoidance unit installed on the drive mobile chassis 1 (mainly used for navigation and obstacle avoidance), a magnetic cruise unit (mainly used for cruising with the magnetic strips, magnetic nails, etc. arranged on the moving route), a QR code scanning module (mainly used for positioning the moving position), a safety protection unit (mainly including anti-collision, safety warning, emergency stop, etc.), a control panel unit (used for setting, controlling operations) and / or a self-charging module (including realizing the power consumption, power monitoring and charging of the power module, and sending signals for judging the end of charging, etc.), which are not numbered in the aforementioned feature diagrams. The intelligent mobile control system includes a remote communication module, a controller, etc., which realizes remote control or remote control by pre-setting or by signal or data transmission with the remote communication module, thereby realizing the movement of the self-moving vehicle, and can perform unmanned driving operation, autonomous navigation or cruising to the weighing station, achieve more accurate station positioning and automatically adjust to the corresponding weighing posture, etc.

[0020] The weighing system 2 is the execution part that realizes the weighing action task. Figure 2 and Figure 3 As shown in the figure, the structure of the utility model is set as a lifting type weighing, by placing the workpiece to be weighed on the weighing turntable, controlling the self-moving vehicle 1 to move and dive under the weighing turntable to perform weighing, the execution part includes a lifting seat 21 arranged on the self-moving vehicle 1, a weighing control system (not numbered in the figure) and a leveling module 22, a weighing module 23 arranged on the lifting seat 21, a centering mechanism 24 arranged on the weighing module 23 and a lifting assembly 25 arranged on the centering mechanism 24, and a horizontal inclination sensor for sensing the horizontal inclination state of the weighing module 23. The weighing control system controls the operation of the weighing system, which may include a remote communication module, a controller, etc., and completes the weighing task and data recording transmission by pre-setting or by remote control or remote control through signal or data transmission with the remote communication module; the lifting component 25 is constructed to be conducive to the stable lifting of the workpiece to be weighed; the lifting seat 21 can rise so that the lifting component 25 can lift the workpiece to be weighed in situ for weighing, and can be retracted after descending, and the overall height is reduced, which can facilitate more flexible shuttle activities in the industrial production line and the frame, that is, the lifting seat 21 is constructed to be a structure that can drive the lifting component 25 to lift or lower; the setting of the horizontal inclination sensor and the leveling module 22 can automatically obtain the horizontal state and adjustment of the weighing module 23 during weighing. The whole weighing module 23 is in a horizontal state, so as to ensure the stable weighing and the effective and accurate weighing data. Therefore, the horizontal inclination sensor is used to sense the horizontal inclination state of the lifting seat 21 and generate a signal. If it is not in a horizontal state, the weighing control system controls the leveling module 22 to adjust it to a horizontal state. Therefore, the leveling module 22 is arranged according to the structure that can be adjusted from the mobile vehicle 1 to make the weighing module 23 in a horizontal state; the centering mechanism 24 is mainly used to center the workpiece to be weighed during lifting, so as to ensure the stability of lifting and the accuracy of weighing data. Therefore, the centering mechanism 24 is constructed into an adjustable lifting component 25 to adapt to the structure of lifting the workpiece to be weighed; and the mobile vehicle 1 and the weighing system 2 can realize the recording and remote transmission of various data. The following is a detailed description of the structural arrangement and position connection relationship of each part of the weighing system 2 in this embodiment in conjunction with the accompanying drawings.

[0021] In the drawings of this embodiment, in order to enable the lifting seat 21 to achieve the characteristics of greater weighing and lifting (i.e., large load-bearing capacity), higher lifting height (i.e., large compression ratio) and lower manufacturing cost, the lifting seat 21 includes a scissor-type lifting mechanism 211 installed on the self-moving vehicle 1 and a horizontal mounting seat 212 connected to the upper end of the scissor-type lifting mechanism 211. The scissor-type lifting mechanism 211 can be combined with the application of a rigid chain. Both are existing technical structural products and can be set up in conventional structural applications. The rigid chain has a small size and good load-bearing performance. The chain of the rigid chain can withstand both tension and It can withstand pressure, so it can ensure smooth movement during lifting and lowering. The kinetic energy of the scissor-type lifting mechanism 211 can use a DC servo motor; the weighing module 23 is fixedly installed on the horizontal mounting seat 212, and the horizontal inclination sensor is also fixedly installed on the horizontal mounting seat 212, centrally arranged, and not visible in the figure. The horizontal inclination sensor determines the horizontal inclination state of the weighing module 23 fixed thereon by sensing the horizontal inclination state of the horizontal mounting seat 212. The weighing module 23 and the horizontal inclination sensor can be applied to existing electronic equipment products.

[0022] The centering mechanism 24, as shown in the figure, includes a base plate 241 fixedly mounted on the weighing module 23, a bidirectional screw drive mechanism 242 respectively arranged on opposite sides of the base plate 241, and two centering sliders 243 with different driving directions respectively arranged on the screw of the bidirectional screw drive mechanism 242. Based on the structural setting of the centering mechanism 24, the lifting assembly 25 includes supporting blocks 251 respectively fixedly mounted on two centering sliders 243 of the same bidirectional screw drive mechanism 242. In this embodiment, it is suitable for the application of smoothly lifting curved surface workpieces. Furthermore, the opposite sides of the two supporting blocks 251 of the same bidirectional screw drive mechanism 242 are respectively formed with inclined surfaces 252 of corresponding angles, and a centering lifting space 253 with V-shaped relative inclined surfaces is formed between the two relative inclined surfaces 252. Through the above-mentioned structural setting, the centering lifting space 253 with V-shaped relative inclined surfaces can make the center of gravity of the lifting be centered. The middle sinking is particularly suitable for the stable lifting of curved surface workpieces. The spacing between the two support blocks 251 can be adjusted through the operation of the bidirectional screw drive mechanism 242 to realize the opening or closing of the two support blocks 251. The spacing between the two support blocks 251 can be controlled and adjusted according to the size of the workpiece to be lifted to avoid the spacing being too wide and the lifting contact surface being too low, which may be affected by other factors, and to avoid the spacing being too narrow and the lifting center of gravity being unstable. Here, in order to avoid the support block 251 contacting the workpiece surface and causing damage, a protective gasket such as felt, silicone pad, etc. can be set on the lifting surface of the support block 251. In addition, for workpieces that are in contact with other planes, the V-shaped relative inclined surface of the centering lifting space 253 can also adapt to lifting applications because the upper end of the support block 251 usually has a plane. Of course, a support block 251 without an inclined surface 252 can also be set.

[0023] The leveling module 22, as shown in FIG. Figure 3 As shown, there are multiple groups of multi-directionally arranged structures that can horizontally and stably support the self-moving vehicle 1. As shown in the figure, there is a group at each of the four corners of the self-moving vehicle 1. The structure of each group includes a supporting foot 221 and a screw lifting drive mechanism 222 that is fixedly installed on the self-moving vehicle 1 and connected to drive the supporting foot 221 to extend or retract. The kinetic energy of the screw lifting drive mechanism 222 is driven by a motor. The structure sets the leveling module 22 with a large supporting driving force, reliable and stable support, simple control and adjustment operation, and high adjustment accuracy.

[0024] A fully automatic mobile weighing equipment with the above structure can be used in the following operation process: when the controller of the intelligent mobile control system receives the operation command of the upper system, the self-moving vehicle 1 moves and positions itself directly below the object to be weighed according to the navigation path, and then the leveling module 22 moves downward until the driving wheel of the self-moving vehicle 1 leaves the ground, and ensures that the driving wheel is in a suspended state. The self-moving vehicle 1 will not deviate during the weighing process. The sensor data of the horizontal inclination sensor is used to determine whether the leveling module 22 is adjusted. After the adjustment of the leveling module 22 is completed, the lifting seat 21 works and moves upward. At the same time, the centering mechanism 24 adjusts the two supporting blocks 251 to an appropriate opening and closing size according to the size of the weighing object. When the two supporting blocks 251 contact the object to be weighed, the lifting seat 21 reduces its speed, and then continues to lift the object to be weighed until it leaves the original placement plane. After the lifting is completed, the weighing data of the weighing module 23 is stable, recorded, and transmitted back to the upper system. After the weighing operation is completed, the lifting seat 21 descends, and the weighing object is placed back to the position before being weighed during the descending process. After the lifting seat 21 descends back to the initial position, the leveling module 22 works to move the supporting feet 221 upward, so that the driving wheel group of the self-moving vehicle 1 contacts the ground, and the self-moving vehicle 1 can return to the standby position or perform the next weighing operation.

[0025] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present utility model.
