[0022] The present utility model provides an AGV cart with an automatic weighing function, as Figure 1As shown in the figure, it includes: a vehicle body 1 and at least one fork arm assembly 2; the fork arm assembly 2 is detachably connected to the vehicle body 1; the fork arm assembly 2 includes a fork arm upper cover 21 and a fork arm lower cover 22; a first weighing module 3 for weighing the picked-up goods once is arranged on the fork arm upper cover 21; a second weighing module 4 for weighing the picked-up goods twice is arranged on the bottom of the fork arm lower cover 22; a vehicle body cover plate 11 is arranged on the top of the vehicle body 1; and a plurality of third weighing modules 5 for weighing the picked-up goods three times are arranged on the vehicle body cover plate 11.

[0023] Specifically, three weighing modules are arranged on the AGV trolley. Among them, the first weighing module 3 is arranged on the fork arm upper cover 21 and is used for weighing the goods picked up by the fork arm for the first time, preliminarily weighing the picked-up goods to obtain the first weighing result; the second weighing module 4 is arranged on the fork arm lower cover 22 and is used for weighing the picked-up goods for the second time to ensure the accuracy of the weighing data and obtain the second weighing result; the third weighing module 5 is arranged on the vehicle body 1 and is used for weighing the picked-up goods for the third time to obtain the third weighing result; by comparing the three weighing results and taking the average value, a more accurate weight of the goods can be obtained, and the weight change of the goods during transportation can be monitored in real time, further increasing the accuracy of detecting the weight of the goods; in the specific use process, each weighing module can be used alone or in combination, further meeting the use requirements in different use scenarios.

[0024] Furthermore, there are also provided: a plurality of module cover plates 12 corresponding to the third weighing module 5 one by one for protecting the third weighing module 5; threaded holes are opened at the top and bottom of the third weighing module 5; the bottom of the weighing module is threadedly connected to the vehicle body cover plate 11; and the top of the weighing module is threadedly connected to the corresponding module cover plate 12.

[0025] Specifically, each third weighing module 5 is equipped with a corresponding module cover plate 12, and threaded holes are provided inside for connecting to the vehicle body cover plate 11, providing additional mechanical protection and improving the durability and stability of the third weighing module 5.

[0026] Furthermore, a square groove 13 corresponding to the fork arm assembly 2 is opened on the vehicle body 1; the fork arm assembly 2 is placed in the square groove 13.

[0027] Specifically, the opened square groove 13 is used to place the fork arm assembly 2, avoiding the fork arm assembly 2 occupying too much space of the vehicle body 1, resulting in a relatively large overall volume of the AGV trolley and reducing the convenience during the actual working process.

[0028] Furthermore, a display screen 14 for displaying the state of the AGV trolley is arranged on the top of the vehicle body 1; the display screen 14 is located among a plurality of the third weighing modules 5.

[0029] Specifically, a display screen 14 is installed on the top of the vehicle body 1 to provide visualization of the operating status and weighing information of the AGV vehicle, and is located between the plurality of third weighing modules 5 to facilitate instant viewing by operators.

[0030] Furthermore, it also includes: a driving assembly 6 corresponding to the fork arm assembly 2 one by one and used for lifting the corresponding fork arm upper cover 21; the driving assembly 6 includes: a driving member 61 and a scissor arm 62; the driving member 61 is detachably connected to the fork arm lower cover 22; the output end of the driving assembly 6 is transmission-connected to the input end of the scissor arm 62; the output end of the scissor arm 62 is hinged to the fork arm upper cover 21.

[0031] Specifically, a corresponding driving assembly 6 is configured to lift the fork arm upper cover 21. The driving assembly 6 includes a driving member 61 and a scissor arm 62. The driving member 61 is detachably connected to the fork arm lower cover 22 to form a flexible lifting system, which provides good power for lifting and forking the fork arm.

[0032] Furthermore, a support rod 63 for supporting the fork arm upper cover 21 is provided; one end of the support rod 63 is hinged to the fork arm lower cover 22 , and the other end is hinged to the scissor arm 62 .

[0033] Specifically, the support rod 63 realizes effective support for the fork arm upper cover 21 through an articulated design, with one end being hinged to the fork arm lower cover 22 and the other end being hinged to the fork arm upper cover 21 to ensure the overall stability of the fork arm assembly 2.

[0034] Furthermore, the first weighing module 3 , the second weighing module 4 and the third weighing module 5 can be used in combination, or can be used independently.

[0035] In implementation one, when the AGV forks goods, the first weighing module 3 on the fork arm upper cover 21 performs a preliminary inspection on the forked goods and obtains a first weighing result, which is a preliminary inspection result; when the goods are forked onto the AGV body 1 and the fork arm assembly 2 is in a retracted state, the second weighing module 4 on the fork arm lower cover 22 weighs the forked goods for a second time and obtains a second weighing result. At the same time, the third weighing module 5 on the body 1 weighs the forked goods for a third time and obtains a third weighing result. By comparing the three weighing results, a more accurate weight of the goods can be obtained.

[0036] In the second embodiment, only the first weighing module 3 and the second weighing module 4 can be used, or only the first weighing module 3 and the third weighing module 5 can be used; the first weighing module 3 on the upper cover 21 of the fork arm conducts a preliminary detection on the picked goods to obtain the first weighing result, and the first weighing result is the preliminary detection result; the second weighing result is obtained through the second weighing module 4 or the third weighing module 5, and the more accurate weight of the goods is obtained by comparing the two weighing results; this weighing method takes less time and is applicable to short-distance transportation. It can monitor the weight change of the picked goods in real time during transportation, avoiding property losses caused by situations such as the weight of the goods dropping due to environmental factors such as vibration during transportation.

[0037] In the third embodiment, only the first weighing module 3, or the second weighing module 4, or the third weighing module 5 can be used alone. The weight of the picked goods can be quickly understood through the results obtained by each weighing module, achieving the effect of real-time monitoring of the goods weight.

[0038] An AGV cart with an automatic weighing function according to the present invention is provided with a first weighing module 3, a second weighing module 4, and a third weighing module 5 on the AGV cart. The three weighing modules can be used in combination, and there are three weighing processes for the picked goods, making the weighing data more accurate; they can also be used alone to obtain the weight of the picked goods, and are used specifically according to the specific scenario, further improving the adaptability of the AGV cart.
