The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0031] See also Figure 1 to Figure 11 In the embodiment of the present invention, the rolling front punching online monitoring and inspection equipment cooperating with the punching action is installed on the punching equipment 1, and the punching equipment 1 is provided with an upper die 4 and a lower die 3, and the upper die 4 is connected to the hydraulic cylinder 5 provided on the punching equipment 1; It includes: a visual inspection device 6 and a telescopic frame.

[0032] The visual inspection device 6 is connected to a limiting assembly installed on the stamping equipment 1, and the limiting assembly can enable the visual inspection device 6 to maintain a state of facing the upper mold 4 or the lower mold 3; A support frame 2 is fixedly mounted on the stamping equipment 1, and the limiting assembly includes a connecting frame 9 detachably connected to the support frame 2. A rotating shaft 7 is rotatably mounted on the connecting frame 9, and the rotating shaft 7 is fixedly connected to the visual inspection device 6. Specifically, the detachable connection between the support frame 2 and the connecting frame 9 includes a bolt connection or a snap connection to improve the portability of the connecting frame 9 for disassembly and assembly.

[0033] The limiting assembly also includes an energy storage structure connected to the connecting frame 9, a follower sleeve 12 is connected to the energy storage structure, the follower sleeve 12 is slidably fitted with the rotating shaft 7, and a hysteresis structure is arranged between the follower sleeve 12 and the rotating shaft 7, the hysteresis structure cooperates with the energy storage structure, and can make the visual detection device 6 deflect upward or downward, the energy storage structure includes a slide groove 901 arranged along the length direction of the connecting frame 9, a sliding connector 10 is slidably installed in the slide groove 901, the sliding connector 10 is fixedly connected to the follower sleeve 12, and a columnar spring 11 is connected to the sliding connector 10, and one end of the columnar spring 11 away from the sliding connector 10 is connected to the side wall of the slide groove 901; The hysteresis structure includes a first protruding shaft 1201 arranged on the inner wall of the follower sleeve 12 and a connecting groove arranged on the outer wall of the rotating shaft 7, and the first protruding shaft 1201 can slide in the connecting groove; The connection groove includes two groups of spiral grooves 701 which are symmetrically arranged along the axial direction of the rotating shaft 7 , and a protrusion 702 is formed at the connection of the two groups of spiral grooves 701 .

[0034] In the initial state, the cylindrical spring 11 is in a stretched state, and at this time the first protruding shaft 1201 is at one end of one of the spiral grooves 701 away from the protrusion 702. In this state, under the action of the elastic force provided by the cylindrical spring 11, the first protruding shaft 1201 can be kept at the end of the spiral groove 701, so that the visual inspection device 6 can maintain a stable deflected state, thereby improving the stability of the visual inspection device 6 when performing inspection operations and ensuring the inspection accuracy.

[0035] Specifically, in the initial state, the upper mold 4 is in a state of being in contact with the lower mold 3, and the cooperation of the two can realize the stamping action on the workpiece. At the same time, the visual inspection device 6 is in an inclined upward state, so that when the upper mold 4 moves upward to separate from the lower mold 3, when the upper mold 4 rises to a predetermined position, the visual inspection device 6 can perform visual inspection on the lower surface of the upper mold 4, and when the upper mold 4 rises to the maximum height, it can drive the visual inspection device 6 to deflect downward through the telescopic frame, so that the visual inspection device 6 can inspect the lower mold 3, including the inspection of the stamped parts and the lower mold 3 itself, and when the stamped parts are removed and new stamping materials are placed, the upper mold 4 can move toward the lower mold 3 to perform During the stamping operation, the upper mold 4 can drive the visual inspection device 6 to deflect in the opposite direction through the telescopic frame and restore to an inclined upward state, thereby realizing the mechanical linkage between the action of the visual inspection device 6 and the action of the upper mold 4, so that during a stamping process, the visual inspection device 6 can follow the action of the upper mold 4 and perform a reciprocating deflection to complete the inspection of the upper mold 4, the lower mold 3, and the parts after stamping, thereby improving the action continuity of the visual inspection device 6 and the coordination with the action of the upper mold 4. Compared with the method of using sensors for coordination in the prior art, the action delay between the action of the visual inspection device 6 and the action of the upper mold 4 is smaller, so that the visual inspection device 6 has sufficient inspection time and the inspection accuracy is improved.

[0036] Furthermore, when the rotating shaft 7 drives the visual inspection device 6 to deflect, the first protruding shaft 1201 can move along the length direction of one set of spiral grooves 701 and further stretch the cylindrical spring 11, and after moving past the protrusion 702, the cylindrical spring 11 can also actively drive the visual inspection device 6 to actively deflect, and deflect the visual inspection device 6 faster and in a shorter time, so that the visual inspection device 6 can quickly switch the deflection state and perform the corresponding inspection operation.

[0037] Through the above-mentioned arrangement, with the cooperation of the spiral groove 701, the first cam shaft 1201 and the cylindrical spring 11, on the one hand, the stability of the visual inspection device 6 under deflection can be guaranteed, so that it has higher stability when performing inspection operations and ensures the inspection accuracy; on the other hand, the visual inspection device 6 can be deflected faster and in a shorter time, so that the visual inspection device 6 can quickly switch the deflection state and perform the corresponding inspection operation.

[0038] See also Figure 3~Figure 4 , Figure 7 The telescopic frame is connected to the upper mold 4, and two groups of abutment portions distributed in the vertical direction of space are formed on the telescopic frame, and the abutment portions are adapted to the trigger plate 8 provided on the limit assembly; When the telescopic frame moves upward to the end of the stroke, the abutment portion at the lower portion can cooperate with the trigger plate 8 to drive the visual inspection device 6 to switch from facing the upper mold 4 to facing the lower mold 3; The telescopic frame body includes a follower 13 detachably connected to the upper mold 4, and a first abutment shaft 14 is mounted on the follower 13; The telescopic frame body further comprises a telescopic frame 15 which is slidably fitted with the follower 13, and a second abutment shaft 16 which is parallel to the first abutment shaft 14 is provided on the telescopic frame 15; The first abutment shaft 14 and the second abutment shaft 16 form two sets of abutment portions; The follower 13 is connected to the telescopic frame 15 via a sliding kit, which includes a hysteresis groove 1301 arranged along the length direction of the follower 13, and a hysteresis shaft 1501 connected to the telescopic frame 15. When the follower 13 descends to the lowest point of the stroke, the hysteresis shaft 1501 can slide in the hysteresis groove 1301.

[0039] When the upper mold 4 performs a stamping action, the follower 13 follows the movement of the upper mold 4 and is at the lowest point of the stroke. At this time, the telescopic frame 15 is partially retracted into the follower 13 due to the lower end abutting against the stamping device 1. At the same time, the visual inspection device 6 is in an upward tilted state. When the upper mold 4 moves upward, the upper mold 4 can drive the follower 13 to move upward. At this time, the telescopic frame 15 can remain stationary and slide relative to the follower 13. When the hysteresis shaft 1501 moves to the lower end of the hysteresis groove 1301, the telescopic frame 15 can It can move upward with the follower 13, and when the upper mold 4 moves to the upper end of the stroke, the second abutment shaft 16 can abut against the trigger plate 8, and the trigger plate 8 drives the rotating shaft 7 to rotate, so that the visual inspection device 6 can deflect downward, and after the first convex shaft 1201 moves over the protrusion 702, the upper mold 4 will stop moving. At this time, the cylindrical spring 11 can actively drive the rotating shaft 7 to rotate until the visual inspection device 6 rotates into place, and the visual inspection device 6 can inspect the lower mold 3 and the stamped parts.

[0040] When the upper mold 4 moves downward again to perform the stamping action, the follower 13 will move downward with the upper mold 4, and when the upper mold 4 moves to the lower end of the stroke, the first abutment shaft 14 will abut against the trigger plate 8 again, so that the rotating shaft 7 can drive the visual inspection device 6 to deflect upward, thereby resetting the visual inspection device 6.

[0041] Through the above-mentioned arrangement, when the upper mold 4 moves, the first abutment shaft 14 and the second abutment shaft 16 can follow the movement, and cooperate with the trigger plate 8 to drive the visual inspection device 6 to perform a deflection movement, so that the movement of the visual inspection device 6 is mechanically linked with the movement of the upper mold 4, and in the process of completing a stamping process, the visual inspection device 6 can follow the movement of the upper mold 4 and perform a reciprocating deflection to complete the inspection of the upper mold 4 and the lower mold 3, and the parts after stamping, thereby improving the movement continuity of the visual inspection device 6 and the coordination with the movement of the upper mold 4.

[0042] See also Figure 2 , Figure 8 The rolling forward punching online monitoring and inspection equipment that cooperates with the punching action also includes: an air supply head 18, a right-angle blocking piece 19 and a switching component.

[0043] The air supply head 18 is connected to the linear drive module 17 disposed on the support frame 2. The air supply head 18 is disposed in a rectangular parallelepiped, and the four sides of the air supply head 18 are provided with conducting grooves 1801. The right-angle blocking members 19 are provided in two groups and are slidably arranged on the inner side of the air supply head 18 . The right-angle blocking members 19 are provided with connecting grooves 1901 adapted to the conducting grooves 1801 .

[0044] When in use, first connect the external air pump device to the air supply head 18 through a pipeline. At this time, the air compressed by the external air pump device can enter the air supply head 18 and be sprayed toward the upper mold 4 and the lower mold 3 through the conducting groove 1801, thereby cleaning the stamping particle dust adhering to the upper mold 4 and the lower mold 3, so as to reduce the influence of the particle dust generated during the stamping process on the detection results. At the same time, the cleaning of the particle dust can also ensure the stamping quality and avoid the presence of particle dust affecting the flatness of the stamped parts.

[0045] It is worth noting that the air supply head 18 is arranged in a rectangular parallelepiped and its diagonals are in the same horizontal plane. At this time, the compressed air injected through the conducting groove 1801 can be injected toward the upper mold 4 and the lower mold 3 at a 45° inclination.

[0046] See also Figure 8~Figure 11 The switching assembly connects the two groups of right-angle blocking members 19, and the switching assembly cooperates with the two groups of trigger members 24 arranged on the support frame 2, so that when the air supply head 18 moves to the end of the stroke, the air supply head 18 is connected to the conducting groove 1801 on one side of the upper mold 4 and the lower mold 3; The switching assembly includes a turntable 22 rotatably mounted on the air supply head 18, and two groups of abutment protrusions 23 are symmetrically arranged on the turntable 22, and the abutment protrusions 23 are adapted to the trigger member 24; An inclined guide surface 2401 is formed on one end of the trigger member 24 facing the rotating disk 22. The inclined guide surface 2401 cooperates with the abutting protrusion 23 to enable the rotating disk 22 to rotate. The switching assembly further includes a connection kit connecting the rotating disk 22 and the two groups of right-angle blocking pieces 19, the connection kit including a connection shaft 20 fixedly connected to the right-angle blocking piece 19 and passing through the air supply head 18, and a second convex shaft 21 is provided at one end of the connection shaft 20 away from the right-angle blocking piece 19; The connection kit further includes an engaging groove 2201 provided on the rotating disk 22 , and the two groups of the second protruding shafts 21 can slide in the engaging groove 2201 .

[0047] In the initial state, the linear drive module 17 can drive the air supply head 18 to move. At this time, the conducting grooves 1801 on the two side surfaces of the air supply head 18 facing the direction of its movement are in a state of overlapping with the connecting grooves 1901, that is, the compressed air can be sprayed through the two side surfaces, while the conducting grooves 1801 on the two side surfaces away from the direction of movement of the air supply head 18 are in a blocked state. When the air supply head 18 moves to the end of the stroke, the abutting protrusions 23 on the turntable 22 can abut against the inclined guide surfaces 2401 on the corresponding triggering member 24, so that the turntable 22 rotates, and at this time, with the cooperation of the second convex shaft 21 and the interlocking groove 2201, the two groups of right-angle blocking members 19 can move synchronously and staggeredly, so that the originally blocked conducting groove 1801 is in a conducting state, and the originally conducted conducting groove 1801 is in a blocked state, so that when the air supply head 18 moves in the reverse direction, the compressed air can always be sprayed in the direction of its movement, that is, the direction in which the air supply head 18 delivers compressed air can always be consistent with its movement direction, so that the compressed air can directionally drive away the particulate dust generated by the stamping, thereby improving the cleaning effect.

[0048] Through the above arrangement, firstly, compressed air is sprayed toward the upper mold 4 and the lower mold 3 through the conducting groove 1801, which can clean the stamping particle dust adhering to the upper mold 4 and the lower mold 3, so as to reduce the influence of the particle dust generated during the stamping process on the detection results. At the same time, the cleaning of the particle dust can also ensure the stamping quality and avoid the existence of particle dust affecting the flatness of the stamped parts. Secondly, the pumping direction of the compressed air can always be consistent with the movement direction of the air supply head 18, so that the compressed air can directionally drive away the particle dust generated by the stamping, thereby improving the cleaning effect.

[0049] As an embodiment of the present invention, a method for performing inspection using the rolling front punching online monitoring and inspection device for cooperating with the punching action is also proposed, comprising the following steps: Step 1: Under the action of the limit assembly, the visual inspection device 6 is in an upward deflection state. At this time, when the stamping is completed, the visual inspection device 6 can first inspect the upper mold 4; Step 2: When the upper mold 4 rises to the end of the stroke, one set of abutment portions on the telescopic frame cooperates with the trigger plate 8, so that the visual inspection device 6 switches from the upward deflection state to the upward deflection state to inspect the lower mold 3; Step 3: When the upper mold 4 moves downward to perform the stamping action, the upper mold 4 can drive the telescopic frame to move again, so that the visual inspection device 6 returns to the upward deflected state; Step 4: Repeat the above steps 1 to 3 so that the visual inspection device 6 can cooperate with the stamping equipment 1 to perform visual inspection.
