[0037] like Figure 1 and Figure 2 As shown, some embodiments of the present application provide an automatic cutting device, including a frame 1, and a mobile platform mechanism 2, a detection mechanism 3 and a cutting mechanism 4 installed on the frame 1. Among them, a placement platform 11 is provided on the frame 1. The mobile platform mechanism 2 is installed on the placement platform 11, and includes a working platform 21, a first moving component 22 and a second moving component 23. The first moving component 22 can drive the working platform 21 to move along a first direction, and the second moving component 23 can drive the working platform 21 to move along a second direction, and the first direction and the second direction are arranged horizontally and vertically, so that the first moving component 22 and the second moving component 23 can drive the working platform 21 to move freely on a horizontal plane. The detection mechanism 3 is located above the working platform 21, and is used to detect local defects of the product 5 placed on the working platform 21. The cutting mechanism 4 includes a matching upper cutting component and a lower cutting component. When the detection mechanism 3 detects a local defect of the product 5, the first moving component 22 and the second moving component 23 move the local defect of the product 5 to the cutting position of the upper cutting component and the lower cutting component to cut off the local defect of the product 5. The detection mechanism 3 can quickly identify local defects of the product 5 and accurately cut them off through the cutting mechanism 4. No human intervention is required throughout the process, which is conducive to improving work efficiency.

[0038] like Figure 3As shown, in some embodiments, the working platform 21 includes a bottom plate 211 and a tray 212 connected to the bottom plate 211. The bottom plate 211 and the tray 212 are hollowed out in the middle so as to make way for the cutting mechanism 4 when cutting local defects of the product 5. A positioning pin 213 is provided on the tray 212 to position the product 5 on the tray 212. Furthermore, a reinforcing rib corresponding to the rib of the product 5 is provided in the hollowed-out middle of the tray 212 to support the product 5.

[0039] In some embodiments, the inspection mechanism 3 is also used to re-inspect the cut product 5 to determine whether the local defects of the product 5 are cut cleanly, so as to ensure that the cut product 5 will not cause residual pins to fall into the mold after entering the next process, resulting in batch defects of the product 5.

[0040] Exemplarily, the detection mechanism 3 includes a bracket 31 and a camera 32 mounted on the bracket 31, and the bracket 31 is mounted on the frame 1 so that the camera 32 is located above the working platform 21. The camera 32 is used to take a picture of the product 5 and detect local defects of the product 5 by image recognition.

[0041] like Figure 4 As shown, in some embodiments, the first moving assembly 22 includes a first driving component, a first guide member 221 and a moving plate 222. The moving plate 222 is connected to the driving end of the first driving component and the first guide member 221 at the same time, so that the first driving component can drive the moving plate 222 to move along the guide direction of the first guide member 221. Since the guide direction of the first guide member 221 is consistent with the first direction, the first driving component can drive the moving plate 222 to move along the first direction.

[0042] Exemplarily, the first driving component includes a first driving member 223, a first transmission screw 224 and a first transmission nut 225. The first driving member 223 is mounted on the placement platform 11, the first transmission nut 225 is mounted on the first transmission screw 224, and the two ends of the first transmission screw 224 are respectively mounted on the driving end of the first driving member 223 and the base 43 of the lower cutting assembly. The moving plate 222 is connected to the first transmission nut 225. When the first driving member 223 drives the first transmission screw 224 to rotate, the length direction of the first transmission screw 224 is consistent with the first direction, so as to drive the moving plate 222 to move along the first direction.

[0043] It should be noted that the first direction can be set to the Y-axis direction, that is, the horizontal longitudinal direction of the placement platform 11.

[0044] Exemplarily, the first driving member 223 provides driving force for the rotation of the first lead screw, including but not limited to being set as a motor, etc.

[0045] like Figure 5 As shown, in some embodiments, the second moving assembly 23 is installed on the moving plate 222, so that the first driving member 223 can drive the second moving assembly 23 to move along the first direction. The second moving assembly 23 includes a second driving component and a second guide member 231, and the guiding direction of the second guide member 231 is consistent with the second direction. The working platform 21 is connected to the driving end of the second driving component and the second guide member 231 at the same time, so that the second driving component can drive the working platform 21 to move along the second direction, that is, the working platform 21 can realize the movement along the first direction and the second direction under the drive of the first moving assembly 22 and the second moving assembly 23.

[0046] Exemplarily, the second driving component includes a second driving member 232, a second transmission lead screw 233, a second transmission nut 234 and a bearing seat 235, wherein the second transmission nut 234 is mounted on the second transmission lead screw 233, and both ends of the second transmission lead screw 233 are respectively connected to the driving end of the second driving member 232 and the bearing seat 235, and the second driving member 232 and the bearing seat 235 are both mounted on the moving plate 222. The working platform 21 is connected to the second transmission nut 234, and when the second driving member 232 drives the second transmission lead screw 233 to rotate, since the length direction of the second transmission lead screw 233 is consistent with the second direction, the working platform 21 is driven to move along the second direction.

[0047] It should be noted that the second direction can be set to the X-axis direction, that is, the horizontal lateral direction of the placement platform 11.

[0048] Exemplarily, the second driving member 232 provides driving force for the rotation of the second lead screw, including but not limited to being set as a motor, etc.

[0049] In some embodiments, the mobile platform mechanism 2 further includes a lifting assembly 24, and the lifting assembly 24 includes a fixed end and a movable end that can move linearly relative to the fixed end. The fixed end of the lifting assembly 24 is connected to the second transmission nut 234 and the second guide member 231 at the same time, so that the second moving assembly 23 can drive the lifting assembly 24 to move along the second direction; the movable end of the lifting structure is connected to the working platform 21, so that the lifting assembly 24 drives the working platform 21 to move along the second direction and approach or move away from the lower cutting assembly.

[0050] When the product 5 is placed on the working platform 21 and the inspection mechanism 3 inspects the product 5, the lifting assembly 24 drives the working platform 21 away from the lower cutting assembly to place the product 5 and inspect the product 5. When the inspection mechanism 3 detects that the product 5 has a local defect, the first moving assembly 22 and the second moving assembly 23 move the local defect of the product 5 to the cutting position of the cutting mechanism 4. Subsequently, the lifting assembly 24 drives the working platform 21 close to the lower cutting assembly so that the cutting mechanism 4 cuts the local defect of the product 5.

[0051] Exemplarily, the fixed end may be set as a guide sleeve 241, and the movable end may be set as a third driving member 242 and a guide column 243. The third driving member 242 is located at the bottom of the working platform 21, and the guide column 243 is installed at the bottom of the working platform 21 and is connected with the guide sleeve 241. When the third driving member 242 drives the working platform 21 to move along the guide direction of the guide sleeve 241, it approaches or moves away from the lower cutting assembly, so that the cutting mechanism 4 cuts the local defects of the product 5 or the detection mechanism 3 detects the local defects of the product 5.

[0052] Exemplarily, the third driving member 242 is installed on the moving plate 222 through a supporting member. The third driving member 242 provides a driving force for the working platform 21 to approach or move away from the lower cutting assembly, including but not limited to being set as a linear cylinder.

[0053] like Figure 6 As shown, in some embodiments, the upper cutting assembly includes a fourth driving member 41 and an upper punch 42, and the upper punch 42 is mounted on the driving end of the fourth driving member 41. The lower cutting assembly includes a base 43 and a lower die 44, and the base 43 is mounted on the placement platform 11, and the lower die 44 is mounted on the upper part of the base 43. The upper punch 42 and the lower die 44 are correspondingly arranged, and when the fourth driving member 41 drives the upper punch 42 to move toward the lower die 44, the local defects of the product 5 are cut.

[0054] Exemplarily, the fourth driving member 41 provides driving force for the movement of the upper punch 42, including but not limited to being set as an electric cylinder, etc.

[0055] In some embodiments, the upper cutting assembly also includes a buffer component installed between the fourth driving member 41 and the upper punch 42. When the fourth driving member 41 drives the upper punch 42 to move toward the lower die 44, the buffer component buffers the cooperation between the upper punch 42 and the lower die 44, thereby preventing the upper punch 42 from crushing the lower die 44 under the drive of the fourth driving member 41.

[0056] Exemplarily, the buffer component includes an upper connecting plate 45 and a lower connecting plate 46, and an elastic member 47 connected between the upper connecting plate 45 and the lower connecting plate 46. The upper connecting plate is mounted on the driving end of the fourth driving member 41, and the upper convex mold 42 is mounted on the side of the lower connecting plate 46 facing the lower concave mold 44.

[0057] Exemplarily, the elastic member 47 includes but is not limited to being set as a spring and the like.

[0058] In some embodiments, a first waste discharge channel 12 is also provided on the frame 1, and the lower cutting assembly is provided with a second waste discharge channel 48 connected to the lower die 44. The first waste discharge channel 12 and the second waste discharge channel 48 are connected to collect local defects cut from the product 5.

[0059] In some embodiments, a display screen 6 is also installed on the frame 1 for displaying the operation content and working status of the automatic cutting device of the present application.

[0060] like Figure 7 As shown, in some embodiments, the automatic cutting device of the present application is further provided with a control host 7, in which a controller 71 is provided, and the controller 71 is electrically connected to the driver 8 and the sensing device 9. The driver 71 is electrically connected to the mobile platform mechanism 2 and the cutting mechanism 4, so that the mobile platform mechanism 2 moves the local defects of the product 5 to the cutting position of the upper cutting component and the lower cutting component, and the cutting mechanism 4 cuts off the local defects of the product 5. The sensing device 9 is electrically connected to the detection mechanism 3, and the sensing device 9 is used to sense whether there is a product 5 placed on the mobile platform mechanism 2. When the product 5 is sensed, the detection mechanism 3 detects the local defects of the product 5.

[0061] To summarize, the present invention provides an automatic cutting device, which detects local defects of products placed on a working platform by setting up a detection mechanism, and drives the local defects of the product to move along a first direction through a first moving component, and drives the local defects of the product to move along a second direction through a second moving component, thereby moving the local defects of the product to the cutting position of the upper cutting component and the lower cutting component to cut off the defective products. The local defects of the product can be quickly identified and accurately removed without manual participation in the entire process, which is conducive to improving work efficiency.
