Description

Technical Field

[0001] The present invention relates to stamping detection technology, specifically an on-line monitoring and inspection device and method for pre-punching rolling in coordination with stamping actions. Background Art

[0002] With the rapid development of the automotive industry, the requirements for the quality and efficiency of auto parts production are getting higher and higher. Most auto parts molds are relatively expensive and precise, and downstream customers have strict requirements for the product supply time. Especially for multi-station stamping, the process is complex, the mold cost is high, and the states of each process need to be consistent.

[0003] In order to ensure reliable stamping quality, it can be detected during the stamping process. Currently, the mainstream detection is mainly visual detection.

[0004] For existing stamping visual detection devices, most of the visual detection devices are connected to the stamping equipment through sensors, that is, the sensors control the visual detection devices to perform detection actions by detecting the state of the stamping equipment. Among them, the delay in the data transmission process will cause a certain action delay between the stamping equipment and the visual detection device, affecting the coordination of their actions. Moreover, the sensors are greatly affected by external factors, resulting in a decrease in the accuracy of their data collection, which will further increase the action delay amount between the stamping equipment and the visual detection device, causing an increase in the action neutral zone between the stamping equipment and the visual detection device. Seriously, the visual detection device will not be able to accurately collect data, affecting the detection results. Summary of the Invention

[0050] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0051] In addition, an element in the present invention is referred to as being "fixed to" or "disposed on" another element, and it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation manner.

[0052] Please refer to Figures 1 to 11 , in the embodiment of the present invention, a pre-rolling forward online monitoring and inspection device for a coordinated stamping action is installed on a stamping device 1. An upper die 4 and a lower die 3 are provided on the stamping device 1, and the upper die 4 is connected to a hydraulic cylinder 5 provided on the stamping device 1;

[0053] It includes: a visual detection device 6 and a telescopic frame body.

[0054] The visual detection device 6 is connected to a limit component installed on the stamping device 1, and the limit component can enable the visual detection device 6 to maintain a state facing the upper die 4 or the lower die 3;

[0055] A support frame body 2 is fixedly installed on the stamping device 1. The limit component includes a connecting frame 9 detachably connected to the support frame body 2. A rotating shaft 7 is rotatably installed on the connecting frame 9, and the rotating shaft 7 is fixedly connected to the visual detection device 6. Specifically, the detachable connection between the support frame body 2 and the connecting frame 9 includes bolt connection or snap connection to improve the disassembly and assembly portability of the connecting frame 9.

[0056] The limiting component further includes an energy storage structure connected to the connecting rod 9. A follower sleeve 12 is connected to the energy storage structure. The follower sleeve 12 is slidably sleeved on the rotating shaft 7. A hysteresis structure is provided between the follower sleeve 12 and the rotating shaft 7. The hysteresis structure cooperates with the energy storage structure to enable the visual detection device 6 to deflect upward or downward. The energy storage structure includes a chute 901 arranged along the length direction of the connecting rod 9. A sliding connector 10 is slidably installed in the chute 901. The sliding connector 10 is fixedly connected to the follower sleeve 12. A cylindrical spring 11 is connected to the sliding connector 10. One end of the cylindrical spring 11 away from the sliding connector 10 is connected to the side wall of the chute 901;

[0057] The hysteresis structure includes a first convex 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. The first convex shaft 1201 can slide in the connecting groove;

[0058] The connecting groove includes two groups of spiral grooves 701 symmetrically arranged along the axial direction of the rotating shaft 7. A protrusion 702 is formed at the connection of the two groups of spiral grooves 701.

[0059] In the initial state, the cylindrical spring 11 is in a stretched state. At this time, the first convex shaft 1201 is at one end of one of the spiral grooves 701 away from the protrusion 702. In this state, under the elastic force provided by the cylindrical spring 11, the first convex shaft 1201 can be kept at the end of the spiral groove 701, so that the visual detection device 6 can maintain a stable deflection state, improve the stability of the visual detection device 6 during the detection operation, and ensure the detection accuracy.

[0060] Specifically, in the initial state, the upper die 4 is in a state of being in contact with the lower die 3. At this time, the cooperation between the two can achieve the stamping action on the workpiece. At the same time, the visual inspection device 6 is in an inclined upward state. When the upper die 4 moves upward to separate from the lower die 3, when the upper die 4 rises to a predetermined position, the visual inspection device 6 can perform visual inspection on the lower surface of the upper die 4. And when the upper die 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 inspects the lower die 3. At this time, it includes the inspection of the stamped parts and the lower die 3 itself. When the stamped parts are removed and new stamping materials are placed, the upper die 4 can move toward the lower die 3 to perform the stamping action. At this time, the upper die 4 can drive the visual inspection device 6 to deflect in the reverse direction through the telescopic frame and return to the inclined upward state, that is, the mechanical interlock between the action of the visual inspection device 6 and the action of the upper die 4 is realized. During one stamping process, the visual inspection device 6 can follow the action of the upper die 4 to perform a reciprocating deflection, and complete the inspection of the upper die 4, the lower die 3, and the stamped parts, improving the action coherence of the visual inspection device 6 and the cooperative matching with the action of the upper die 4. Compared with the existing technology that uses sensors for cooperative matching, the action delay between the action of the visual inspection device 6 and the action of the upper die 4 is smaller, so that the visual inspection device 6 has sufficient inspection time and improves the inspection accuracy.

[0061] Further, when the rotating shaft 7 drives the visual inspection device 6 to deflect, the first convex shaft 1201 can move along the length direction of one set of spiral grooves 701 and further stretch the cylindrical spring 11. And when it moves past the protrusion 702, the cylindrical spring 11 can also actively drive the visual inspection device 6 to deflect actively, making the visual inspection device 6 deflect faster and in a shorter time, so that the visual inspection device 6 can quickly switch the deflection state to perform the corresponding inspection operation.

[0062] Through the above settings, with the cooperation of the spiral grooves 701, the first convex shaft 1201 and the cylindrical spring 11, on the one hand, it can ensure the stability of the visual inspection device 6 during deflection, so that its stability during the inspection operation is higher, ensuring the inspection accuracy. On the other hand, it can make the visual inspection device 6 deflect faster and in a shorter time, so that the visual inspection device 6 can quickly switch the deflection state to perform the corresponding inspection operation.

[0063] Please refer to Figures 3 to 4 、 Figure 7 , the telescopic frame is connected to the upper die 4, and two sets of abutting parts are formed on the telescopic frame and are distributed in the vertical direction of space. The abutting parts are adapted to the trigger plate 8 provided on the limit assembly;

[0064] When the telescopic frame moves upward to the end of the stroke, the abutting part located at the lower part can cooperate with the trigger plate 8 to drive the visual detection device 6 to switch from facing the upper die 4 to facing the lower die 3;

[0065] The telescopic frame includes a follower 13 detachably connected to the upper die 4, and a first abutting shaft 14 is installed on the follower 13;

[0066] The telescopic frame further includes a telescopic frame 15 slidably sleeved with the follower 13, and a second abutting shaft 16 parallel to the first abutting shaft 14 is arranged on the telescopic frame 15;

[0067] The first abutting shaft 14 and the second abutting shaft 16 form two groups of abutting parts;

[0068] The follower 13 and the telescopic frame 15 are connected by a sliding kit. The sliding kit includes a retention groove 1301 arranged along the length direction of the follower 13 and a retention shaft 1501 connected to the telescopic frame 15. When the follower 13 descends to the lowest point of the stroke, the retention shaft 1501 can slide in the retention groove 1301.

[0069] When the upper die 4 performs a stamping action, the follower 13 follows the upper die 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 being in contact with the stamping equipment 1. At the same time, the visual detection device 6 is in an upwardly inclined state. When the upper die 4 moves upward, the upper die 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 retention shaft 1501 moves to the lower end of the retention groove 1301, the telescopic frame 15 can follow the follower 13 to move upward together. When the upper die 4 moves to the upper end of the stroke, the second abutting shaft 16 can abut against the trigger plate 8, and the trigger plate 8 is used to drive the rotating shaft 7 to rotate, so that the visual detection device 6 can deflect downward. After the first convex shaft 1201 moves past the protruding part 702, the upper die 4 will stop moving. At this time, the cylindrical spring 11 can actively drive the rotating shaft 7 to rotate until the visual detection device 6 rotates into place. At this time, the visual detection device 6 can detect the lower die 3 and the stamped part.

[0070] When the upper die 4 moves downward again to perform a stamping action, the follower 13 will follow the upper die 4 to move downward again. When the upper die 4 moves to the lower end of the stroke, the first abutting shaft 14 will abut against the trigger plate 8 again, and the rotating shaft 7 can drive the visual detection device 6 to deflect upward, so that the visual detection device 6 is reset.

[0071] With the above settings, when the upper die 4 moves, the first abutting shaft 14 and the second abutting shaft 16 can follow the movement, and cooperate with the trigger plate 8 to drive the vision detection device 6 to perform a deflection action, so that the action of the vision detection device 6 is mechanically interlocked with the action of the upper die 4. During a stamping process, the vision detection device 6 can follow the movement of the upper die 4 to perform a reciprocating deflection once, and complete the detection of the upper die 4, the lower die 3, and the stamped part, improving the action coherence of the vision detection device 6 and the cooperative matching with the action of the upper die 4.

[0072] Please refer to Figure 2 、 Figure 8 , the in-line monitoring and inspection equipment for co-matching stamping actions further includes: an air supply head 18, a right-angle plugging member 19, and a switching assembly.

[0073] The air supply head 18 is connected to the linear drive module 17 provided on the support frame 2. The air supply head 18 is arranged in a cuboid shape, and conduction grooves 1801 are provided on four side edges of the air supply head 18;

[0074] There are two groups of right-angle plugging members 19 which are slidably arranged inside the air supply head 18, and communication grooves 1901 adapted to the conduction grooves 1801 are provided on the right-angle plugging members 19.

[0075] During use, first connect the external air pumping device to the air supply head 18 through pipelines. At this time, the air compressed by the external air pumping device can enter the air supply head 18 and be sprayed onto the upper die 4 and the lower die 3 through the conduction grooves 1801, so as to clean the stamping particle dust adhering to the upper die 4 and the lower die 3, reduce the influence of the particle dust generated during the stamping process on the detection results, and 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 part.

[0076] It should be noted that the air supply head 18 is arranged in a cuboid shape and its diagonals are on the same horizontal plane. At this time, the compressed air sprayed through the conduction grooves 1801 can be sprayed onto the upper die 4 and the lower die 3 in a 45° inclined state.

[0077] Please refer to Figures 8 to 11 , the switching assembly is connected to the two groups of right-angle plugging members 19, and cooperates with two groups of trigger members 24 provided on the support frame 2, and can make the conduction grooves 1801 on the side of the air supply head 18 facing the upper die 4 and the lower die 3 conduct when the air supply head 18 moves to the end of the stroke;

[0078] 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;

[0079] 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.

[0080] 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;

[0081] The connection kit further includes an engaging groove 2201 disposed on the rotating disk 22 , and the two groups of the second protruding shafts 21 can slide in the engaging groove 2201 .

[0082] 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.

[0083] 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.

[0084] As an embodiment of the present invention, a method for inspection using the online monitoring and inspection device for forward rolling with coordinated stamping actions is also proposed, including the following steps:

[0085] Step 1: Under the action of the limit component, the visual detection device 6 is in an upwardly deflected state. At this time, when the stamping is completed, the visual detection device 6 can first detect the upper die 4;

[0086] Step 2: When the upper die 4 rises to the end of the stroke, one set of abutting parts on the telescopic frame body cooperate with the trigger plate 8, so that the visual detection device 6 switches from the upwardly deflected state to the upwardly deflected state to detect the lower die 3;

[0087] Step 3: When the upper die 4 moves downward to perform the stamping action, the upper die 4 can drive the telescopic frame body to act again, so that the visual detection device 6 returns to the upwardly deflected state;

[0088] Step 4: Repeat the above steps 1 to 3, so that the visual detection device 6 can cooperate with the stamping device 1 for visual inspection.
