[0002] When performing fine-grained parts processing, CNC machine tools (CNC) are usually used for automated processing. CNC is an automated machine tool equipped with a program control system. It can input information into the CNC device through an information carrier, and after calculation and processing, the CNC device sends various control signals to control the movement of the machine tool. It automatically processes parts according to the shape and size required by the drawing.

[0003] When performing automated processing on some small precision parts, it is usually necessary to use a fixture to clamp the raw material, and then extend the raw material to a certain distance to feed the CNC.

DETAILED DESCRIPTION

[0027] The following is combined with Figure 1 -Attached Figure 3 , further details of this application are given.

[0028] When performing automated processing on some small precision parts, it is usually necessary to use a fixture to clamp the raw material, and then extend the raw material to a certain distance for feeding to the CNC. Due to the small size of the parts and the short distance the raw material is extended, the accuracy requirements for the fixture feeding are higher. In the prior art, when the CNC completes the processing of the previous batch of parts, it is usually necessary for the staff to manually control the fixture to feed the next batch of raw materials. The manual control method results in a slow feeding speed, which is prone to problems such as low processing efficiency and low finished product yield. Therefore, the present application provides an automatic feeding control system, referring to Figure 1 and Figure 2, including a controller 1, a driving device 2, a clamping device 3 and a relay module 4. Among them, the driving device 2 is the part of the automatic feeding device used to drive the raw material to move up and down, that is, for feeding, and the clamping device 3 is the part of the automatic feeding device used to clamp and fix the raw material, that is, for clamping. The controller 1 includes a driving signal output terminal 11, a clamping signal output terminal 12, a CNC control signal output terminal 13 and a CNC feedback signal input terminal 14. The driving signal output terminal 11 of the controller 1 is connected to the driving device 2. When the feeding process starts, the controller 1 generates a driving signal and sends the driving signal to the driving device 2, so that the driving device 2 drives the raw material to move upward by a preset feeding distance. The clamping signal output terminal 12 of the controller 1 is connected to the clamping device 3. After the driving device 2 drives the raw material to move upward by a preset feeding distance, the controller 1 generates a clamping signal and sends the clamping signal to the clamping device 3, so that the clamping device 3 clamps the raw material after moving upward. The CNC control signal output terminal 13 and the CNC feedback signal output terminal of the controller 1 are connected to the relay module 4, and the relay module 4 is connected to the external CNC. After the clamping device 3 clamps the raw material, the controller 1 generates a CNC control signal and sends the CNC control signal to the external CNC through the relay module 4, so that the external CNC starts processing. When the external CNC processing is completed, the external CNC generates a CNC feedback signal and sends the CNC feedback signal to the controller 1 through the relay module 4, so that the controller 1 starts the next feeding process until all feeding processes are completed.

[0029] The implementation principle of the embodiment of the present application is: the feeding, clamping and external CNC processing are uniformly controlled by the controller 1, and the next feeding process is started by receiving the CNC feedback signal after the external CNC processing is completed. No manual operation is required throughout the process, which effectively improves the feeding efficiency of CNC automated processing of precision parts.

[0030] During the specific implementation process, the clamping device 3 is controlled to open and close through the solenoid valve, thereby controlling the clamping or loosening of the raw material. During the upward movement of the driving device 2, the clamping device 3 needs to be synchronously controlled to loosen the raw material to ensure that the raw material can move upward under the drive of the driving device 2.

[0031] like Figure 1 As shown, since the driving device 2 drives the raw materials to move upward during the feeding process, the driving device 2 needs to be reset after all feeding processes are completed. Therefore, the initial position of the driving device 2 of the present application is provided with a plurality of sensors 5, and the controller 1 also includes an origin signal input terminal 15. The origin signal input terminal 15 of the controller 1 is connected to a plurality of sensors 5 through an origin signal line. When all feeding processes are completed, the controller 1 controls the driving device 2 to descend to the initial position and triggers the sensor 5. The sensor 5 triggers the generation of the origin signal and sends it to the controller 1. After receiving the origin signal, the controller 1 records the position of the driving device 2 as zero.

[0032] In the specific implementation process, the driving device 2 of the embodiment of the present application includes four drivers 21, and the four drivers 21 drive four motors 22 respectively, and also includes a moving plate for placing and driving the raw materials to move up and down. The moving plate is driven by the driving motor 22 so that it can move up and down, and four sensors 5 are provided accordingly. When resetting, the driving motor 22 drives the moving plate to move downward until it hits the sensor 5. The sensor 5 triggers the generation of the origin signal and sends it to the controller 1. After the controller 1 receives the origin signal, it indicates that the moving plate has been reset to the initial position, and the position of the driving device 2 is recorded as zero, so as to facilitate the subsequent new raw material feeding process.

[0033] like Figure 1 As shown, the relay module 4 of the embodiment of the present application includes a first relay 41 and a second relay 42, the first relay 41 is connected to the CNC control signal output terminal 13 of the controller 1 and the control terminal of the external CNC, and the second relay 42 is connected to the feedback terminal of the external CNC and the CNC feedback signal input terminal 14 of the controller 1. The CNC control signal and the CNC feedback signal are transmitted respectively by the first relay 41 and the second relay 42, and the relay can amplify the CNC control signal and the CNC feedback signal, thereby expanding the control range of the controller 1.

[0034] like Figure 1 As shown, the embodiment of the present application further includes a transfer connection board 6, which connects the clamping signal output terminal 12 of the controller 1 and the clamping device 3, and the transfer connection board 6 is also connected to an external power supply. The external power supply is connected through the transfer connection board 6 to ensure that the power supply input to the automatic feeding control system meets the voltage required by the controller 1.

[0035] like Figure 1 As shown, the embodiment of the present application further includes a switch module 7, which connects the external power supply and the clamping device 3. When the switch module 7 is closed, the external power supply and the clamping device 3 are connected; when the switch module 7 is disconnected, the external power supply and the clamping device 3 are disconnected. In the specific implementation process, the external power supply and the clamping device 3 are directly turned on or off by the switch module 7. When an unexpected situation occurs that causes a control system failure or when maintenance is required, the clamping device 3 can be manually controlled to work by the switch module 7.

[0036] like Figure 1As shown, the switch module 7 of the embodiment of the present application is also connected to the external power supply and the first relay 41. When the switch module 7 is closed, the external power supply and the first relay 41 are connected; when the switch module 7 is disconnected, the external power supply and the first relay 41 are disconnected. In the specific implementation process, the external power supply and the first relay 41 are directly turned on or off by the switch module 7. When an unexpected situation occurs and causes a control system failure or during maintenance, the switch module 7 can be manually operated to control the first relay 41 to turn on, thereby controlling the external CNC connected to the first relay 41 to work.

[0037] The present application also provides an automatic feeding control method, referring to Figure 3 , applied to an automatic feeding control system, including a feeding process S1, specifically including: S11, when the feeding process starts, the controller 1 generates a driving signal and sends the driving signal to the driving device 2, so that the driving device 2 drives the raw material to move upward a preset feeding distance.

[0038] Specifically, the controller 1 controls the driving device 2 through a driving signal to drive the raw material to move upward. The preset feeding distance is set according to the size of the parts currently to be processed. The feeding distance of each part is pre-stored in the controller 1. When the feeding process starts, the controller 1 calls the corresponding feeding distance, adds the feeding distance to the driving signal and sends it to the driving device 2, thereby controlling the driving device 2 according to the feeding distance.

[0039] S12. After the driving device 2 drives the raw material to move upward by a preset feeding distance, the controller 1 generates a clamping signal and sends the clamping signal to the clamping device 3, so that the clamping device 3 clamps the raw material after moving upward.

[0040] Specifically, since the raw material needs to be clamped and fixed during CNC processing, when the raw material rises to the required feeding distance, the controller 1 continues to control the clamping device 3 to clamp and fix the raw material.

[0041] S13, after the clamping device 3 clamps the raw material, the controller 1 generates a CNC control signal and sends the CNC control signal to the external CNC through the relay module 4, so that the external CNC starts processing.

[0042] Specifically, the CNC control signal contains the processing data of the current part, and the processing data includes processing procedures, processing drawings and other data. When the external CNC receives the CNC control signal, it can process the raw material according to the processing data.

[0043] S14, when the external CNC processing is completed, the external CNC generates a CNC feedback signal and sends the CNC feedback signal to the controller 1 through the relay module 4, so that the controller 1 starts the next feeding process.

[0044] Specifically, after the current processing flow is completed, it is necessary to continue feeding for the next batch of parts processing. The controller 1 receives the CNC feedback signal to know that the current processing has been completed, and automatically enters the next feeding process, returns to step S11 to loop until all feeding processes of the current raw material are completed.

[0045] In order to retrieve processing data, the embodiment of the present application also includes a processing data acquisition process S2 before the feeding process starts, which specifically includes: S21. The controller 1 obtains current raw material information through a visual inspection device.

[0046] Specifically, after the raw materials are placed on the automatic feeding device, the visual inspection equipment can collect image data of the raw materials and perform image recognition on the image data, so that the current raw material information can be obtained based on the image recognition.

[0047] S22. The controller 1 obtains pre-stored processing data according to the raw material information.

[0048] Specifically, the controller 1 stores processing data corresponding to different raw material information, and the processing data includes information such as feeding distance, processing flow and processing drawings. After obtaining the current raw material information, the corresponding processing data can be retrieved according to the current raw material information.

[0049] S23, the controller 1 starts the feeding process according to the processing data.

[0050] Specifically, the controller 1 controls the driving device 2 to feed the material according to the feeding distance in the processing data, and controls the external CNC to process the raw material according to the processing flow and processing drawings in the processing data.

[0051] Since a raw material can be processed multiple times to obtain multiple parts, the specific number of processing times is set according to actual needs. After the processing is completed according to the number of processing times, waste may remain. Therefore, the embodiment of the present application also includes a waste recovery process S3 after all feeding processes are completed, which specifically includes: S31. The controller 1 uses a visual inspection device to determine whether there is waste material.

[0052] Specifically, the visual inspection equipment collects the current raw material image, performs image recognition on the image, and determines whether there is any waste material. If there is no waste material, the next raw material processing can be carried out directly.

[0053] S32. When there is waste, the controller 1 controls the clamping device 3 to release the waste, and controls the waste recovery device to recover the waste.

[0054] Specifically, the controller 1 controls the clamping device 3 to release the waste, and then recycles the waste. The waste recycling device can use a manipulator and other equipment to transfer the waste released by the clamping device 3 to a waste storage for unified treatment.

[0055] Since the driving device 2 drives the raw materials to move upward during the feeding process, the driving device 2 needs to be reset after all feeding processes are completed. The reset process S4 specifically includes: S41 , the controller 1 controls the driving device 2 to descend to the initial position and triggers the sensor 5 .

[0056] Specifically, the sensor 5 is arranged at the initial position of the driving device 2 , so when the driving device 2 descends to trigger the sensor 5 , it indicates that the driving device 2 has descended to the initial position.

[0057] S42 , the sensor 5 is triggered to generate an origin signal and send it to the controller 1 .

[0058] Specifically, the origin signal is used to identify the initial position and plays an important role in mechanical positioning. S43. After receiving the origin signal, the controller 1 records the position of the driving device 2 as zero.

[0059] Specifically, after the controller 1 receives the origin signal, it indicates that the movable plate has been reset to the initial position, and the position of the driving device 2 is recorded as zero to facilitate the subsequent new raw material feeding process.

[0060] The implementation principle of the embodiment of the present application is: automatically identify the raw materials to obtain processing data, and then generate drive signals, clamping signals and CNC control signals through the controller 1 to achieve full automation of feeding, clamping and processing, and start the next feeding process by receiving the CNC feedback signal after the external CNC processing is completed, and automatically perform waste recovery and reset the drive device 2 after all feeding processes are completed. No manual operation is required throughout the process, which effectively improves the feeding efficiency of CNC automated processing of precision parts.

[0061] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
