[0002] The laser tube cutting equipment bed consists of a laser tube cutting device and a matching fully automated tube feeding device. When conducting aging tests on a newly introduced laser tube cutting equipment bed, both the laser tube cutting device and the fully automated tube feeding device need to be installed in the factory and tested as a whole. However, in actual production scenarios, it's not always possible to install both devices simultaneously. After the fully automated tube feeding device is installed, it must wait for the laser tube cutting device to complete the test, as the fully automated tube feeding device cannot perform the test independently. This limits the testing conditions and reduces testing efficiency. Summary of the Invention

[0042] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this invention.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0044] The independent testing method for pipe feeding equipment provided in this embodiment of the invention is executed by computer equipment, and correspondingly, the independent testing system for pipe feeding equipment runs in computer equipment.

[0045] Figure 1 This is a schematic flowchart illustrating a method according to an embodiment of the present invention. Wherein, Figure 1 The executing entity can be an independent testing system for pipe feeding equipment. Depending on different requirements, the order of steps in this flowchart can be changed, and some steps can be omitted.

[0046] like Figure 1 As shown, the method includes:

[0047] Step 110: Simulate and generate the presence signal of the laser tube cutting equipment, and control the tube feeding equipment to execute the feeding program;

[0048] Step 120: Collect position detection data of the first sensor during the pipe feeding process on the pipe feeding equipment. The first sensor is set at a key position on the pipe feeding equipment.

[0049] Step 130: Collect the weight data of the transported pipes collected by the second sensor, which is installed on the pipe receiving equipment;

[0050] Step 140: Generate test results for the pipe feeding equipment based on location detection data, weight data, and pipe transport record data of the pipe feeding equipment.

[0051] To facilitate understanding of the present invention, the following description further illustrates the independent testing method for pipe feeding equipment provided by the present invention, based on the principle of the method and the process of independently testing the pipe feeding equipment in the embodiments.

[0052] Specifically, the independent testing method for the pipe feeding equipment includes:

[0053] S1. Simulate and generate the presence signal of the laser tube cutting equipment, and control the tube feeding equipment to execute the feeding program.

[0054] The laser pipe cutting equipment recognition option parameter of the PLC of the pipe feeding equipment is modified to "recognized" using a pre-edited test script.

[0055] The above method is licensed at the software level. In other embodiments of the present invention, a relay can also be connected to generate a switching signal, thereby simulating the presence signal of the laser tube cutting device.

[0056] After the pipe feeding equipment starts feeding, the specific feeding steps are as follows:

[0057] (1) The pipe material is placed on the material carrier belt. The quantity of pipe material is preset in the test script, and the feeding equipment is started.

[0058] (2) The material carrier belt starts feeding the tube material to the feeding mechanism area. The material carrier belt feeding is frequency-controlled, which can adjust the speed.

[0059] (3) The material feeding mechanism delivers the pipe material to the top material area. The material feeding mechanism delivers the pipe material to the top material area through vertical lifting and horizontal movement. The material feeding mechanism adopts servo drive control, which utilizes the characteristics of fast response speed, high positioning accuracy and reliable stability of servo drive to realize the pipe material conveying.

[0060] (4) The top feeding mechanism rises to deliver the pipe to the clamping mechanism area. After the pipe arrives at the top feeding mechanism, the top feeding mechanism rises to deliver the pipe to the clamping mechanism area. The top feeding mechanism is frequency-controlled, which can realize speed adjustment.

[0061] (5) The clamp arm moves to the area where the clamp can clamp the pipe, the clamp tightens the pipe, and delivers the pipe to the waiting position. The movement of the clamp arm is servo driven. The clamp clamping is pneumatically controlled. A waiting trolley is set up at the waiting position. The waiting trolley is equipped with a pressure sensor. After the waiting trolley is full, it transports the pipe to the material carrier belt for cyclic testing.

[0062] S2. Collect position detection data of the first sensor during the pipe feeding process on the pipe feeding equipment. The first sensor is set at a key position on the pipe feeding equipment.

[0063] After receiving the location identification signal sent by the first sensor, the timestamp of the received signal is recorded in a pre-created location monitoring list.

[0064] Photoelectric switches are installed at key locations on the pipe feeding equipment to detect whether the pipe has passed through that location during the feeding process. For example, a photoelectric switch can be installed at the junction of the feeding mechanism and the top feeding mechanism. The photoelectric switches are connected to the PLC.

[0065] When a pipe passes the photoelectric switch, the PLC receives the signal and records the timestamp of the received signal in the monitoring list. Theoretically, each pipe transported corresponds to a timestamp. However, if the pipe is skewed, the photoelectric switch may not detect its passage, indicating a problem with the pipe feeding equipment that needs to be calibrated.

[0066] S3. Collect the weight data of the transported pipes collected by the second sensor, which is installed on the pipe receiving equipment.

[0067] The system receives pressure data from the second sensor and converts the pressure data into gravity data according to a pre-set rule; it calculates the fluctuation value of the gravity data and the time when the fluctuation occurs; it filters out the fluctuation value and the corresponding fluctuation time that match the weight of a single pipe and saves them as pipe data to the acceptance record list.

[0068] Similarly, the pressure sensor on the material receiving vehicle is first connected to a controller, such as a CPLD (Complex Programmable Logic Device), and then the pressure sensor value is sent to the PLC via a wireless communication module. Assuming a vehicle can carry 20 pipes, the PLC receives the pressure values ​​periodically reported by the CPLD and converts them into weight values. It calculates the difference between the current weight value and the previous weight value; if the difference equals the weight of one pipe, a timestamp is generated. The timestamp is then saved to the receiving record list.

[0069] S4. Generate test results for the pipe feeding equipment based on position detection data, weight data, and pipe transport record data of the pipe feeding equipment.

[0070] Determine if the pipe delivery record data matches the data in the location monitoring list and the acceptance record list: if yes, the pipe loading equipment is deemed to have passed the test; if no, the pipe loading equipment is deemed to have failed the test.

[0071] Specifically, the total number of pipes transported for the test device and the time of each pipe transport are obtained from the pipe transport record data of the PLC.

[0072] The test is considered normal if the number of timestamps is equal to the total number of pipes transported, based on the time required for each pipe to be transported to the key location and the matching timestamps in the monitoring list. The number of transports that do not have matching timestamps is output as abnormal transports.

[0073] The test is considered normal if the number of timestamps in the acceptance record list is counted and equal to the total number of pipes transported. If the number of timestamps is not equal to the total number of pipes transported, the test is further conducted by searching for the matching timestamps in the acceptance record list for each pipe transport time based on the time required to transport the pipes to the waiting vehicle. The number of transports that do not have matching timestamps is output as the number of abnormal transports.

[0074] This invention enables the feeding equipment to undergo trial operation and aging before being connected to the cutting machine, simulating the actual working motion when connected to the cutting machine. This overcomes the problem of production capacity being affected by waiting for the cutting machine to be tested before adjusting the feeding equipment. To some extent, it improves work efficiency and shortens the production cycle.

[0075] In some embodiments, the independent testing system 200 for pipe feeding equipment may include multiple functional modules composed of computer program segments. The computer programs for each program segment in the independent testing system 200 may be stored in the memory of a computer device and executed by at least one processor to perform (see details).
