[0002] As we all know, equipment needs to undergo rigorous testing before it is put into production. For example, the loading and unloading performance of the transportation equipment must be tested. The currently commonly used testing method is to test whether each transportation equipment can jointly transport the materials to the destination. If so, it is determined that the performance of the transportation equipment is good. However, in actual scenarios, the successful transportation of materials only indicates that the transported products are qualified, and cannot reflect the loading and unloading performance of the transportation equipment.

[0062] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0063] Reference Figure 1 , Figure 1 This is a structural diagram of the loading and unloading test equipment in the hardware operating environment involved in the embodiment of the present invention.

The memory 1005 may optionally be a storage device independent of the aforementioned processor 1001.

[0065] Those skilled in the art will understand that Figure 1 The structure shown in the figure does not constitute a limitation on the loading and unloading test equipment, and may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0066] like Figure 1 As shown, the memory 1005 as a storage medium may include an operating system, a network communication module, a user interface module, and a loading and unloading test program.

[0067] exist Figure 1 In the loading and unloading test equipment shown, the network interface 1004 is mainly used for data communication with the network integration platform workstation; the user interface 1003 is mainly used for data interaction with the user; the processor 1001 and the memory 1005 in the loading and unloading test equipment of the present invention can be set in the loading and unloading test equipment, and the loading and unloading test equipment calls the loading and unloading test program stored in the memory 1005 through the processor 1001, and executes the loading and unloading test method provided by the embodiment of the present invention.

[0068] Based on the above hardware structure, an embodiment of the loading and unloading testing method of the present invention is proposed.

[0069] Reference Figure 2 , Figure 2 Schematic diagram of the flow of the first embodiment of the loading and unloading testing method of the present invention.

[0070] In a first embodiment, the loading and unloading test method includes the following steps:

[0071] Step S10: upon receiving the loading and unloading test instruction, obtaining the adsorption force of the target material transported by the first transport equipment.

[0072] It should be noted that the executor of this embodiment is the loading and unloading test equipment, and it can also be other equipment that can achieve the same or similar functions, such as a test controller, etc. This embodiment does not limit this. In this embodiment, the test controller is used as an example for explanation.

[0073] It should be understood that the loading and unloading test instruction refers to an instruction for testing the loading and unloading performance of the transportation equipment. The loading and unloading test instruction can be sent by the control center. The target material can be a magnetic workpiece. The first transportation equipment refers to the equipment for transporting the target material. The first transportation equipment can be a robot. The adsorption force refers to the suction force of the suction nozzle on the first transportation equipment to absorb the target material. The greater the adsorption force, the more difficult it is for the target material to fall when the first transportation equipment is transporting it.

[0074] Step S20: When it is detected that the target material is placed on the conveyor belt of the second transport equipment, an initial image and an initial weight of the target material are obtained.

[0075] It can be understood that the initial image refers to the image of the target material at the moment it is placed on the conveyor belt of the second transport equipment, the initial weight refers to the weight of the target material placed on the conveyor belt of the second transport equipment, and the second transport equipment refers to the equipment that transports the target material. The second transport equipment can be a conveyor. When it is detected that the target material is placed on the conveyor belt of the second transport equipment, it indicates that the first transport equipment has transported the target material and placed it on the conveyor belt of the second transport equipment. At this time, the initial image and initial weight of the target material are obtained.

[0076] Step S30: determining an initial position of the target material on the second transport device according to the initial image.

[0077] It should be understood that the initial position refers to the position of the target material on the conveyor belt of the second transport equipment, and the initial position can be represented by coordinates.

[0078] Further, step S30 includes: obtaining the first end point of the second transport equipment and the transport direction of the conveyor belt of the second transport equipment; constructing a spatial rectangular coordinate system based on the first end point and the transport direction; determining the first distance between the target material and the first boundary of the conveyor belt and the first distance between the target material and the second boundary of the conveyor belt based on the initial image; determining the initial position of the target material on the second transport equipment based on the first distance between the target material and the first boundary of the conveyor belt and the first distance between the target material and the second boundary of the conveyor belt through the spatial rectangular coordinate system.

[0079] It can be understood that the first endpoint can be the lower right endpoint of the transport equipment, and the transmission direction refers to the direction in which the conveyor belt of the second transport equipment transmits the target material, and the transmission direction includes the downward transmission direction and the upward transmission direction. Then, the first endpoint is used as the coordinate origin, and the horizontal axis is established with the transmission direction parallel to the conveyor belt and the vertical axis is established with the transmission direction perpendicular to the conveyor belt, thereby completing the establishment of the spatial rectangular coordinate system. The first boundary refers to the boundary of the transmission direction parallel to the conveyor belt, and the second boundary refers to the boundary of the transmission direction perpendicular to the conveyor belt. Then, the initial position of the target material on the second transport equipment is determined. For example, the first distance between the target material and the first boundary of the conveyor belt is 10 cm, and the first distance between the target material and the second boundary of the conveyor belt is 16 cm. Then the initial position of the target material on the second transport equipment is (10, 16).

[0080] Step S40: After the test is completed, the time consumed for transporting the target material, the target position, and the target weight are determined.

[0081] It can be understood that the time spent on transporting the target material refers to the time spent on transporting the target material from one end of the conveyor belt to the other end, the target position refers to the position of the target material on the boundary of the conveyor belt after the test is completed, and the target weight refers to the total weight of the target material after the test is completed. Since deviations may occur during transportation, resulting in loss of the target material, the weight of the target material after the test is completed may be inconsistent with the initial weight.

[0082] Furthermore, step S40 includes: after the test is completed, obtaining the transmission start time and transmission end time of the target material; calculating the time consumed in transmitting the target material based on the transmission start time and transmission end time; obtaining a target image of the target material, and determining the second distance between the target material and the first boundary of the conveyor belt and the second distance between the target material and the second boundary of the conveyor belt based on the target image; determining the target position based on the second distance between the target material and the first boundary of the conveyor belt and the second distance between the target material and the second boundary of the conveyor belt through a spatial rectangular coordinate system.

[0083] It should be understood that the transmission start time refers to the time when the second transport equipment starts to transport the target material, and the transmission end time refers to the time when the second transport equipment ends to transport the target material. Then, the time consumed to transport the target material is calculated based on the transmission start time and the transmission end time. For example, the transmission start time is 14:01:51, and the transmission end time is 14:09:58, then the time consumed to transport the target material is 8 minutes and 7 seconds. After obtaining the second distance between the target material and the first boundary of the conveyor belt and the second distance between the target material and the second boundary of the conveyor belt, the target position is determined. For example, the second distance between the target material and the first boundary of the conveyor belt is 1300 cm, and the first distance between the target material and the second boundary of the conveyor belt is 12 cm, then the initial position of the target material on the second transport equipment is (1300, 12).

[0084] Step S50 , obtaining a test result of the loading and unloading performance of the transport equipment according to the adsorption force, time, initial weight, target weight, initial position and target position.

[0085] It should be understood that after obtaining the time, initial weight, target weight, initial position and target position, the test results of the loading and unloading performance of the transportation equipment are comprehensively obtained in combination with the adsorption force of the target material transported by the first transportation equipment.

[0086] Furthermore, after step S50, it also includes: obtaining a total performance characteristic value based on the test results of the loading and unloading performance of the transportation equipment; when the total performance characteristic value is less than a preset performance characteristic threshold, obtaining a test result of the transmission performance of the loading and unloading of the second transportation equipment based on the test results of the loading and unloading performance of the transportation equipment; comparing the transmission loss performance characteristic value, the transmission stability performance characteristic value and the transmission efficiency performance characteristic value in the test results of the transmission performance of the loading and unloading of the second transportation equipment with the corresponding performance characteristic values; analyzing the comparison results of the performance characteristic values ​​to obtain the loading and unloading performance influencing factors; and adjusting the components of the second transportation equipment according to the loading and unloading performance influencing factors.

[0087] It can be understood that the total performance characteristic value refers to a characteristic value that characterizes the loading and unloading performance of the transportation equipment. The total performance characteristic value can be obtained by accumulating the product of the performance characteristic values ​​of each indicator and the set weight. When it is determined that the total performance characteristic value is less than the preset performance characteristic threshold, it indicates that the loading and unloading performance of the transportation equipment is poor. At this time, it cannot be put into production and performance optimization is required. Since the performance of the first transportation equipment has little impact on the total performance characteristic value, the performance of the second transportation equipment is optimized at this time. Specifically, the transmission loss performance characteristic value, the transmission stability performance characteristic value and the transmission efficiency performance characteristic value in the test results of the transmission performance of the loading and unloading of the second transportation equipment are compared with the corresponding performance characteristic values, and then the comparison results of the performance characteristic values ​​are analyzed. For example, the comparison results of the performance characteristic values ​​are that the transmission loss performance characteristic value is lower than the preset loss performance characteristic threshold and the transmission stability performance characteristic value is lower than the preset stability performance characteristic threshold. Then, it is analyzed that the influencing factor of the loading and unloading performance may be the loosening of the installation point of the conveyor belt, which in turn causes friction damage to the conveyor belt. At this time, the components of the second transportation equipment are adjusted according to the influencing factors of the loading and unloading performance, specifically by replacing the conveyor belt and tightening the installation point.

[0088] Furthermore, the components of the second transport equipment are adjusted according to the factors affecting the loading and unloading performance, including: determining the transmission loss performance characteristic value, transmission stability performance characteristic value and transmission efficiency performance characteristic value of the loading and unloading of the second transport equipment after adjusting the components; calculating the target total performance characteristic value according to the transmission loss performance characteristic value, transmission stability performance characteristic value, transmission efficiency performance characteristic value and the test results of the transportation performance of the loading and unloading of the first transport equipment; when the performance characteristic value is greater than or equal to the preset performance characteristic threshold, the test results of the transportation performance of the loading and unloading of the first transport equipment and the test results of the loading and unloading of the second transport equipment after adjusting the components are displayed.

[0089] It should be understood that after adjusting the components of the second transport equipment, the transmission loss performance characteristic value, transmission stability performance characteristic value and transmission efficiency performance characteristic value of the second transport equipment for loading and unloading after the components are adjusted are determined, and then the target total performance characteristic value is calculated based on the transmission loss performance characteristic value, transmission stability performance characteristic value, transmission efficiency performance characteristic value and the set weight of the second transport equipment for loading and unloading after the entire components are adjusted, and then it is determined whether the performance characteristic value is greater than or equal to the preset performance characteristic threshold. If so, the test results of the transportation performance of the first transport equipment for loading and unloading and the test results of the second transport equipment for loading and unloading after the components are adjusted are displayed, indicating that the loading and unloading performance of the first transport equipment and the second transport equipment are better and can be put into production and use.

[0090] This embodiment obtains the adsorption force of the target material transported by the first transport equipment when receiving the loading and unloading test instruction; obtains the initial image and initial weight of the target material when detecting that the target material is placed on the conveyor belt of the second transport equipment; determines the initial position of the target material on the second transport equipment according to the initial image; after the test, determines the time consumed for transporting the target material, the target position and the target weight; obtains the test results of the loading and unloading performance of the transport equipment according to the adsorption force, time, initial weight, target weight, initial position and target position; through the above method, after obtaining the adsorption force, the test results of the loading and unloading performance of the transport equipment are jointly determined in combination with the time consumed for transporting the target material, the initial weight, target weight, initial position and target position, thereby effectively improving the efficiency and accuracy of the test.

[0091] In one embodiment, if Figure 3 Based on the first embodiment, a second embodiment of the material loading and unloading test method of the present invention is proposed. Step S50 includes:

[0092] Step S501: obtaining a critical value for adsorption and detachment of a target material from a first transport device.

[0093] It should be understood that the critical value refers to the adsorption critical value at which the target material falls from the suction nozzle of the first transport equipment. When the adsorption force of the suction nozzle of the first transport equipment is less than the critical value, it indicates that the first transport equipment cannot transport the target material to the conveyor belt of the second transport equipment.

[0094] Step S502: obtaining a moving speed of the first transport equipment in transporting the target material.

[0095] It can be understood that the moving speed refers to the speed at which the first transport equipment transports the target material to the conveyor belt of the second transport equipment. In order to effectively improve the transmission efficiency, the moving speed is greater than the running speed of the conveyor belt of the second transport equipment.

[0096] Step S503: determining the inertia borne by the target material according to the moving speed.

[0097] It should be understood that inertia refers to the force exerted on the target material due to inertia when the first transporting equipment transports the target material. The faster the moving speed, the greater the inertia exerted on the target material.

[0098] Step S504 : Calculating a target adsorption force according to the inertia and adsorption force borne by the target material.

[0099] It can be understood that the target adsorption force refers to the adsorption force of the suction nozzle on the target material after taking into account the inertia. The direction of the force corresponding to the inertia is consistent with the transport direction of the first transport equipment. The target adsorption force is then calculated based on the force corresponding to the inertia and the adsorption force borne by the target material.

[0100] Step S505 , calculating the adsorption difference between the target adsorption force and the critical value of adsorption / desorption.

[0101] It should be understood that the adsorption difference refers to the difference between the target adsorption force and the critical value of adsorption separation. In order to ensure that the first transport equipment transports the target material, the target adsorption force is greater than the critical value of adsorption separation.

[0102] Step S506: obtaining a test result of the loading and unloading transportation performance of the first transportation equipment according to the adsorption difference.

[0103] It can be understood that after obtaining the adsorption difference between the target adsorption force and the critical value of adsorption detachment, the test results of the transportation performance of the first transportation equipment for loading and unloading materials are obtained according to the adsorption difference, that is, the larger the adsorption difference, the better the transportation performance of the first transportation equipment for loading and unloading materials.

[0104] Step S507 , obtaining a test result of the transport performance of the second transport equipment for loading and unloading materials according to the time, initial weight, target weight, initial position, and target position.

[0105] Furthermore, step S507 includes: calculating the weight difference between the initial weight and the target weight; determining the transmission loss performance characteristic value of the second transport equipment for loading and unloading based on the weight difference; determining the coordinate deviation based on the coordinates of the initial position and the coordinates of the target position; determining the transmission stability performance characteristic value of the second transport equipment for loading and unloading based on the coordinate deviation; obtaining the shortest transportation time of the same type of transport equipment; calculating the time difference between the time and the shortest transportation time; determining the transmission efficiency performance characteristic value of the second transport equipment for loading and unloading based on the time difference; obtaining the test results of the transmission performance of the second transport equipment for loading and unloading based on the transmission loss performance characteristic value, the transmission stability performance characteristic value and the transmission efficiency performance characteristic value.

[0106] It can be understood that after obtaining the target weight, the weight difference between the initial weight and the target weight is calculated, and then the transmission loss performance characteristic value of the second transport equipment for loading and unloading is calculated based on the weight difference and the transmission loss performance characteristic coefficient, and after obtaining the target position, the coordinate deviation is determined based on the coordinates of the initial position and the coordinates of the target position, and then the transmission stability performance characteristic value of the second transport equipment for loading and unloading is calculated based on the coordinate deviation and the transmission stability performance characteristic coefficient, and after obtaining the shortest transportation time, the time difference between the time and the shortest transportation time is calculated, and then the transmission efficiency performance characteristic value of the second transport equipment for loading and unloading is calculated based on the time difference and the transmission efficiency performance characteristic coefficient, and finally the test results of the transmission performance of the second transport equipment for loading and unloading are obtained based on the transmission loss performance characteristic value, the transmission stability performance characteristic value and the transmission efficiency performance characteristic value.

[0107] This embodiment obtains the critical value of adsorption and detachment between the target material and the first transport equipment; obtains the moving speed of the first transport equipment transporting the target material; determines the inertia borne by the target material according to the moving speed; calculates the target adsorption force according to the inertia borne by the target material and the adsorption force; calculates the adsorption difference between the target adsorption force and the critical value of adsorption and detachment; obtains the test result of the transportation performance of the first transport equipment for loading and unloading materials according to the adsorption difference; obtains the test result of the transmission performance of the second transport equipment for loading and unloading materials according to the time, initial weight, target weight, initial position and target position; through the above method, the test result of the transportation performance of the first transport equipment for loading and unloading materials is obtained according to the adsorption difference between the target adsorption force and the critical value of adsorption and detachment, and the test result of the transmission performance of the second transport equipment for loading and unloading materials is obtained according to the time, initial weight, target weight, initial position and target position, thereby effectively improving the accuracy of the performance test results of each transport equipment.

[0108] In addition, an embodiment of the present invention further proposes a storage medium, on which a loading and unloading test program is stored. When the loading and unloading test program is executed by a processor, the steps of the loading and unloading test method described above are implemented.

[0109] Since the storage medium adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0110] In addition, refer to Figure 4 The embodiment of the present invention further provides a loading and unloading testing device, the loading and unloading testing device comprising:

[0111] The receiving module 10 is used to obtain the adsorption force of the target material transported by the first transport equipment when receiving the loading and unloading test instruction.

[0112] The acquisition module 20 is configured to acquire an initial image and an initial weight of the target material when detecting that the target material is placed on the conveyor belt of the second transport equipment.

[0113] The determination module 30 is configured to determine an initial position of the target material on the second transport device according to the initial image.

[0114] The determination module 30 is further configured to determine the time consumed for transporting the target material, the target position, and the target weight after the test is completed.
