[0029] It should be noted that the terms used herein are only for the purpose of describing specific embodiments, and are not intended to limit the exemplary embodiments according to the present application. As used herein, the singular form is intended to include the plural form unless the context clearly indicates otherwise, and furthermore, it should be understood that when the terms "comprise" and / or "include" are used in the specification, they indicate the presence of a feature, step, operation, device, component and / or combination thereof.

[0030] As shown in Figures 1 to 5 In the present embodiment, the transfer system comprises a mechanical arm 100, a suction device group 120 and a control device. The base station 110 is connected to the mechanical arm 100, and the base station 110 has a picking position, a waste releasing position and a workpiece releasing position. The suction device group 120 is arranged at the bottom of the base station 110, and the suction device group 120 comprises a first suction device 121 and a second suction device 122 located on the circumferential outer side of the first suction device 121. The first suction device 121 and the second suction device 122 are electrically connected to the control device to realize the switching between the suction state and the release state. In the case that the base station 110 is located at the picking position, the control device controls the first suction device 121 and the second suction device 122 to be in the suction state. In the case that the base station 110 is located at the waste releasing position, the control device controls the first suction device 121 to be in the suction state and the second suction device 122 to be in the release state. In the case that the base station 110 is located at the workpiece releasing position, the control device controls the first suction device 121 to be in the release state.

[0031] The technical scheme of the embodiment is applied, after the punch press is completed, the waste 3 generated by the punch press is left on the punch press. At this time, the control device moves the base 110 to the taking position and controls the first adsorption device 121 and the second adsorption device 122 to be in the adsorption state. At this time, the first adsorption device 121 adsorbs the workpiece 2 to be processed, and the second adsorption device 122 adsorbs the waste 3 on the punch press. Then, the control device controls the mechanical arm 100 to move the base 110 to the waste releasing position. When the base 110 reaches the waste releasing position, the control device controls the second adsorption device 122 to switch to the releasing state, at this time, the waste 3 falls into the preset position for collection, and the workpiece 2 to be processed is continuously transported. When the base 110 reaches the workpiece releasing position, the control device controls the first adsorption device 121 to be in the releasing state, so as to release the workpiece 2 to be processed to the preset position for subsequent processing. That is, the above-mentioned transfer system not only can transfer the workpiece to the next position, but also has the effect of transferring the waste generated in the previous punching step to the preset position, realizing the automatic collection of the waste and reducing the labor intensity of the workers.

[0032] As shown in Figures 1 to 4 , in the embodiment, the first adsorption device 121 includes a first vacuum chuck 123a and a first vacuum pump, and the second adsorption device 122 includes a second vacuum chuck 123b and a second vacuum pump, and the control device is electrically connected with the first vacuum pump and the second vacuum pump. The above-mentioned structure is simple, easy to realize and low in cost. Of course, in other embodiments not shown in the figure, the first adsorption device and the second adsorption device can be electromagnetic adsorption devices.

[0033] As shown in Figure 2 and Figure 3 , in the embodiment, the second vacuum chuck 123b is arranged outside the four corners of the first adsorption device 121. The above-mentioned structure makes the waste generated by the punch press at the four corners be sucked away, thereby further reducing the amount of waste around the punch press.

[0034] Because there is a distance between the waste 3 and the upper surface of the workpiece 2 to be processed during the punching process. In order to enable the first vacuum chuck 123a and the second vacuum chuck 123b to successfully adsorb the workpiece 2 to be processed and the waste 3, as shown in Figure 1 , in the embodiment, the first plane where the second vacuum chuck 123b is located is lower than the second plane where the first vacuum chuck 123a is located, and the distance between the first plane and the second plane is a preset value. The above-mentioned structure makes the first vacuum chuck 123a be able to directly contact the upper surface of the workpiece 2 to be processed and the second vacuum chuck 123b be able to directly contact the waste 3 when the base 110 moves to the taking position, without having to adjust the height, thereby making the transfer system more efficient.

[0035] Of course, in other embodiments not shown in the figures, the second adsorption device 122 further comprises a height adjusting member arranged on the base 110, and the second vacuum chuck 123b is arranged on the height adjusting member. The above structure makes the displacement of the second vacuum chuck 123b in the vertical direction adjustable, that is, when the punching depth of the part 2 to be processed changes, the height of the second vacuum chuck 123b can be adjusted by the height adjusting member, so that the distance between the first plane and the second plane meets the new preset value. Therefore, the above structure has higher universality.

[0036] Of course, in other embodiments not shown in the figures, the base 110 can comprise a first mold group and a second mold group arranged vertically in the horizontal plane, the first mold group is arranged on the slider of the second mold group, and the second vacuum chuck 123b is arranged on the slider of the first mold group, so that the position of the second vacuum chuck 123b in the horizontal plane is adjustable, thereby further improving the universality of the transfer system.

[0037] As shown in Figure 1 and Figure 2 In the present embodiment, the transfer system 160 further comprises a horizontal extension arm 130, and the output shaft of the mechanical arm 100 is drivingly connected to one end of the extension arm 130 to make the extension arm 130 rotate in the horizontal plane, and the base 110 is fixed to the other end of the extension arm 130. The above structure makes the range of movement of the base 110 larger, thereby meeting the actual requirements.

[0038] As shown in Figure 5 The present application also provides a punching line, and an embodiment of the punching line according to the present application comprises a first punching bed 140, a second punching bed 150 and a transfer system 160, wherein the transfer system 160 is arranged between the first punching bed 140 and the second punching bed 150, and the transfer system 160 is the above-mentioned transfer system. When the base 110 is in the taking position, the base 110 is opposite to the working position of the first punching bed 140, when the base 110 is in the waste releasing position, the base 110 is between the first punching bed 140 and the second punching bed 150, and when the base 110 is in the workpiece releasing position, the base 110 is opposite to the working position of the second punching bed 150. Since the above-mentioned transfer system has the advantages of automatically collecting waste and reducing the labor intensity of workers, the punching line with the same also has the above-mentioned advantages.

[0039] As shown in Figure 5As shown, in the present embodiment, the stamping line further comprises a waste collecting bin 170. The waste collecting bin 170 is arranged between the first stamping bed 140 and the second stamping bed 150, and the base 110 is opposite to a waste inlet of the waste collecting bin 170 when the base 110 is in the waste releasing position. The above structure enables the waste 3 to be automatically collected in the collecting device, thereby facilitating the subsequent waste treatment.

[0040] In the present embodiment, the bottom of the waste collecting bin 170 is provided with a moving device (not shown in the figure). The above structure enables the waste collecting bin 170 to be easily transferred to a preset position, thereby facilitating the waste pouring.

[0041] In the present embodiment, the waste collecting bin 170 is provided with a sensor (not shown in the figure) for detecting whether the waste fills the waste collecting bin 170, and the sensor is electrically connected to the control device. Specifically, in the present embodiment, the sensor is a gravity sensor, and when the weight of the waste collecting bin 170 reaches a preset value, the control device alarms. At this time, the worker can move away the waste collecting bin 170 filled with waste, and move the empty waste collecting bin 170 to the preset position to continue to receive the waste.
