It is understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for the convenience of description, only the parts related to the present invention are shown in the accompanying drawings, rather than all the contents.

[0025] like Figure 1-5 As shown, the strip material special-shaped end chamfering processing equipment provided by the embodiment of the present invention comprises: a frame 6 and a conveying roller 1 arranged on the frame 6, an end chamfering processing mechanism, a supporting and conveying mechanism, and a follow-up scanning and positioning mechanism.

[0026] The conveyor roller 1 is arranged along the length direction of the frame 6, and the conveyor roller 1 provides rotational power for the conveyor roller through the conveying motor and the chain sprocket transmission. The roller of the conveyor roller 1 is provided with a roller 20 at one end close to the upper crossbeam. A plurality of rollers 20 form a roller line.

[0027] The input end of the frame 6 is connected to the strip feeding device 21, and the strip feeding device 21 transfers the strips between the chamfering machine of the strip automatic processing production line and the chamfering processing equipment of this embodiment. A photoelectric sensor is provided at the input end of the frame 6, and when the strips are input into the chamfering processing equipment of the present invention, the photoelectric sensor can sense the signal. An upper crossbeam and a middle crossbeam parallel to the conveying direction of the conveyor roller 1 are provided on one side of the frame 6, and a blanking platform 18 is provided on the other side; a plurality of storage racks 19 are arranged below the blanking platform 18, and the storage racks 19 can receive the strips dropped from the blanking platform 18.

[0028] The end chamfering processing mechanism is slidably arranged on the upper crossbeam. The end chamfering processing mechanism includes: an x-axis module 7, a y-axis module 8 and a z-axis module 9; the x-axis module 7 is arranged on the upper crossbeam; the x-axis module 7 is slidably connected to multiple groups of y-axis modules 8, the y-axis module 8 is slidably connected to the z-axis module 9, and a processing power head 10 is installed at the terminal of the z-axis module 9. The processing power head 10 can adopt a special power head for intelligent chamfering of special-shaped steel plates. The processing power head 10 can be moved in space under the mutual cooperation of the x-axis module 7, the y-axis module 8 and the z-axis module 9.

[0029] The support and transfer mechanism includes: multiple groups of single-axis robots 2; the single-axis robots 2 are arranged below the conveying roller 1, and the conveying direction of the single-axis robots 2 is perpendicular to the conveying direction of the conveying roller 1. The single-axis robot 2 is equipped with a blocking cylinder 3 and a supporting cylinder 4, and the blocking cylinder 3 is located on the side close to the blanking table 18; the plunger of the supporting cylinder 4 is equipped with an electromagnet 5, and the electromagnet 5 can absorb the strip when it is energized; the initial positions of the blocking cylinder 3 and the supporting cylinder 4 are between two adjacent rollers of the conveying roller 1, and the blocking cylinder 3 and the supporting cylinder 4 can move in the y-axis direction under the drive of the single-axis robot 2, and the electromagnet 5 can support the strip, so that the supporting cylinder 4 drives the strip to move to the processing position.

[0030] like Figure 6As shown, the follow-up scanning positioning mechanism includes: a follow-up module 11 arranged on the middle cross beam, and at least one group of follow-up modules is slidably installed on the follow-up module 11. The follow-up module 11 is parallel to the conveying direction of the conveyor roller 1. The follow-up module includes: a sliding structure 12, a baffle lifting cylinder 14 and a group of contour scanning sensors 13; the sliding structure 12 is cooperatively arranged on the follow-up module 11, and the sliding structure 12 can slide on the follow-up module 11. The contour scanning sensor 13 is arranged on the sliding structure 12, and the baffle lifting cylinder 14 is vertically downwardly installed at the bottom of the sliding structure 12; a lifting block 15 is installed at the plunger end of the baffle lifting cylinder 14, and a baffle 16 is elastically installed on one side of the lifting block 15. Specifically, the baffle 16 is installed on one side of the lifting block 15 through a sliding rod and a spring. A displacement sensor 17 is also installed on the lifting block 15.

[0031] In addition, the bar material special-shaped end chamfering processing equipment of this embodiment also includes an external numerical control operation box and an air source. The pneumatic components in this embodiment are connected to the air source. The electric components and the air source are both electrically connected to the numerical control operation box.

[0032] The working process of the bar material special-shaped end chamfering processing equipment provided in this embodiment is as follows:

[0033] Strip input: the blocking cylinder 3 and the supporting cylinder 4 are initially in a descending state, and the follower module is initially at the input end of the conveyor roller 1; the strip is conveyed from the strip feeding device 21 to the conveyor roller 1, and the photoelectric sensor senses the signal of the strip input; the baffle lifting cylinder 14 descends, driving the baffle 16 to descend; when the strip flows into the equipment along the roller line reference edge (the long side of the strip may not be completely close to the roller line reference edge), the special-shaped end of the strip contacts the baffle 16, the displacement sensor 17 feedbacks the signal, and the follower module follows the roller line. The follower module accurately records the length direction position of the strip. After it is in place, the support transfer mechanism works to move the strip horizontally; a power device can be set in the sliding structure 12 of the follower module, which can be reset under the action of the power device.

[0034] Strip profile scanning: The single-axis robot 2 works, driving the blocking cylinder 3 and the supporting cylinder 4 to move. The blocking cylinder 3 rises and pushes the strip to the reference edge of the roller line. The blocking cylinder 3 drops and resets. The single-axis robot 2 moves the supporting cylinder 4 to the center of the strip width direction. The supporting cylinder 4 rises, the electromagnet 5 is energized, and the strip rises. At this time, the baffle lifting cylinder 14 rises, and the electromagnet 5 absorbs the strip to position. The follower module moves along the roller line direction, and the profile scanning sensor 13 works until the profile scanning is completed.

[0035] The strip is transferred to the processing position: the single-axis robot 2 moves toward the blanking table 18, and the supporting cylinder 4 moves the strip to the processing position close to the edge of the equipment. The trajectory formed after the contour scanning sensor 13 scans the contour is calculated and compared with the electromagnet distribution coordinates for automatic avoidance.

[0036] Strip material processing: The processing power head 10 of the end chamfering processing mechanism processes according to the trajectory obtained after the contour scanning. After the processing is completed, the processing power head 10 returns to the origin, and the single-axis robot 2 moves the strip material to the unloading position at the edge of the equipment. The supporting cylinder 4 descends and the electromagnet 5 loses power, and the strip material slides along the unloading table 18 to the storage rack 19.

[0037] The device of this embodiment can be provided with a plurality of positioning and processing areas. When the first strip is transversely moved to the processing area, the second strip can enter the device for positioning, scanning and processing.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that modifying the technical solutions described in the aforementioned embodiments, or replacing some or all of the technical features therein by equivalents, does not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
