[0002] During the stamping die production process, due to material and process reasons, the fixed area of ​​the parts will be filled with chips. The generation of chips cannot be eliminated by optimizing the die cutting edge, flanging in sequence, etc., which eventually causes shutdown and part repair. At present, the known solutions to solve the chips include die cutting edge clearance, verticality, finish, flanging in sequence, intact rate, etc. When the above measures cannot solve the chips, the shutdown caused by chips cannot be solved. In addition, in the traditional method, according to the principle of chip cutting generation, the chips in some areas cannot be solved. Summary of the invention

[0003] In view of the above problems, the present invention provides a method and device for cleaning stamping parts on an automated production line, which uses a purge device to blow stubborn chips away from the workpiece, thereby eliminating the problem of padding chips.

[0005] Furthermore, the controller starts compressed air blowing according to a preset cycle or triggers compressed air blowing according to preset conditions, for example, setting the cycle according to the time it takes for the workpiece to be transferred between two processes, or triggering the blowing according to a sensor when the workpiece passes a certain position, so that the chips can be cleaned up in time.

[0006] Furthermore, the controller can adjust the blowing direction and blowing intensity of the compressed air blowing, so that the blowing direction and blowing intensity can be adjusted according to specific circumstances to ensure effective cleaning of the material chips.

[0007] The present invention further provides a stamping part material chip cleaning device on an automated production line, which includes a purge device, the purge device including: a controller, a compressed air supply device, an air intake pipeline and a purge nozzle, the compressed air control valve of the air supply device is connected to the controller, the air supply device is controlled by the controller to deliver compressed air to the purge nozzle through the air intake pipeline, and the purge nozzle is installed on the end picker. Installing the purge nozzle with the help of the end picker can avoid occupying the floor space of the production line on the one hand, and can also more conveniently install the air intake pipeline and electrical circuits on the other hand.

[0008] Furthermore, the purge nozzle is connected to the end effector via a universal mechanism.

[0009] Furthermore, the universal mechanism is electrically connected to the controller so that the jet direction of the purge nozzle can be conveniently adjusted through the controller.

[0010] Furthermore, a speed regulating valve is provided on the air intake pipeline, and the speed regulating valve is electrically connected to the controller so that the jet blowing intensity can be more conveniently controlled by the controller.

[0011] Furthermore, the controller opens the compressed air control valve according to a preset cycle or preset conditions.

[0012] Furthermore, the diameter of the air inlet port of the purge nozzle is smaller than the diameter of the air outlet port, so as to enhance the strength of the jet airflow and ensure the efficiency of chip cleaning.

[0013] The beneficial effects of the present invention are:

[0014] (1) The present invention breaks the conventional thinking and decomposes the process of padding crumbs into steps. According to the conventional method, optimization is performed from the perspective of avoiding the “generation of crumbs”, while the present invention starts from the perspective of “the transportation of crumbs accompanying parts”. By removing the crumbs on the parts, the generation of padding crumbs and machine downtime is avoided, thereby improving production efficiency.

[0019] The technical scheme of the preferred embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Embodiment 1:

[0021] This embodiment provides a method for cleaning the material chips of stamping parts on an automated production line, which includes cleaning the material chips between the process of generating the material chips and the stamping process (such as Figure 1 and Figure 2 The step of blowing the location of the padding crumbs is performed between the S3 step and the S4 step as shown, wherein the blowing step is performed by blowing with compressed air, and the compressed air blowing is controlled by a controller. Figure 1 The figure shows a production line of the prior art. As shown in the figure, the residual chips after the S3 process will cause the workpiece to be padded with chips during the stamping process of the S4 process, resulting in an indentation defect. The method of this embodiment is used to blow the chips away from the workpiece after the S3 process, which can effectively avoid the occurrence of this defect. Figure 2 shown.

[0022] In a preferred embodiment, the controller starts compressed air purge according to a preset cycle or triggers compressed air purge according to preset conditions; preferably, the purge direction and purge intensity can be adjusted by the controller.

[0023] Embodiment 2:

[0024] This embodiment provides a stamping parts material chip cleaning device on an automated production line, such as Figure 2 and Figure 3 As shown, it includes a purge device, which includes: a controller 1, a compressed air supply device, an air intake pipeline 20 and a purge nozzle 33. The compressed air control valve 21 of the air supply device is connected to the controller 1. The air supply device is controlled by the controller to deliver compressed air to the purge nozzle 33 through the air intake pipeline. The purge nozzle 33 is installed on the end effector. The purge nozzle 33 is connected to the end effector through a universal mechanism 32.

[0025] Preferably, the universal mechanism 32 is electrically connected to the controller 1. A speed regulating valve 23 is provided on the air intake pipeline 20, and the speed regulating valve 23 is electrically connected to the controller 1 so as to adjust the airflow intensity through electrical control.

[0026] In a preferred embodiment, the controller 1 opens the compressed air control valve according to a preset cycle or preset conditions. To enhance the purging intensity, the air inlet port diameter of the purging nozzle is smaller than the air outlet port diameter to enhance the intensity of the airflow ejected by the purging nozzle and ensure the cleaning efficiency.

[0027] This embodiment can be combined with existing equipment and components. The following uses the application in a fast horizontal bar type automatic conveying system (SpeedBar) as an example to illustrate the specific implementation method and specific functions of each part:

[0028] Controller 1: The controller 1 can be directly edited and implemented by borrowing the original control unit of the equipment, or an independent controller can be set up separately. In the illustrated embodiment, the controller that is only used to control the cylinder action of the SpeedBar end picker in the prior art is transferred to the control of the purge device. Relying on the cam angle of the automation equipment for control, the compressed air output end of the SpeedBar realizes cyclic and timed blowing, that is, during a certain period of time in the process of SpeedBar transporting parts, the purge device blows the gasket chips from the inside to the outside of the parts, and it is performed once for each piece.

[0029] Inlet pipe 20: responsible for the compressed air transmission between the SpeedBar compressed air output end and the purge nozzle. This unit combines the air line connector and the air pipe connector, and the air pipe connector and the universal unit. The air pipe is color-coded and fixed with a band. The throttle speed regulating valve 23 is used to control the air blowing intensity of the air line to prevent the chips from having adverse effects on the surrounding equipment and molds.

[0030] Fixed wing 31: fixedly connects the universal mechanism 32 and the end tool, and can adjust different angles.

[0031] Universal mechanism 32: realizes the adjustment of the blowing direction of the parts and connects the air inlet pipeline 20 and the purge nozzle 33.

[0032] Blowing nozzle 33: The compressed air is ejected at high pressure by narrowing the air path. The actual application is the sheet material layer blowing joint. This unit expands the new use of the blowing joint by changing its shape.

[0033] In summary, in the closed automated cold stamping parts production process, the present invention realizes the functions of circulating and regularly cleaning part material chips through the application of existing equipment, component assembly, and air blow joint deformation, thereby avoiding the possibility of subsequent workstations stopping due to the generation of padding chips, improving production efficiency, avoiding the generation of quality defects in part padding chips, and reducing part rework costs.

[0034] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it.
