[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Embodiment 1 See also Figure 1-Figure 8 A vehicle battery pack upper cover stamping device with a self-checking function comprises a stamping bed 1 and a press 11 mounted on the stamping bed 1, characterized in that: a conveying path 13, a discharge mechanism 2, a cleaning component 4 and a detection component 5 are arranged on the stamping bed 1, the conveying path 13 is located on the side of the press 11, a discharge port 131 is opened on one end thereof close to the press 11, an electric conveyor belt 14 is installed in the conveying path 13, the discharge mechanism 2 comprises a fixed plate 22 and a discharge rod 3, the fixed plate 22 is mounted on the upper side of the stamping bed 1, located above the conveying path 13, the fixed plate 22 can move horizontally on the stamping bed 1, and two discharge rods 3 are symmetrically connected to one end of the fixed plate 22 facing the press 11, and the discharge rods 3 are arranged in sequence A fixed clamp 31 and a movable clamp 37 are provided. When the fixed plate 22 moves, the two unloading rods 3 are driven to move toward each other and clamp the two sides of the workpiece. At the same time, the unloading rod 3 drives the movable clamp 37 to move toward the fixed clamp 31 to clamp the end of the workpiece, so that the workpiece is sent from under the press 11 into the conveying path 13. The cleaning component 4 includes a cleaning brush 43. The cleaning brush 43 is installed at the top of one end of the conveying path 13 close to the unloading port 131 and cooperates with the electric conveyor belt 14. When the electric conveyor belt 14 transports the workpiece to the detection component 5, it drives the cleaning brush 43 to rotate on the fixed disk 41. The detection component 5 is installed at the top of the conveying path 13, on the side of the fixed disk 41 away from the unloading port 131, and is used to detect the cleaned workpiece.

[0020] When in use, the sheet is first punched into a workpiece by the press 11. At this time, the fixed plate 22 is close to the press 11 in the initial state, and the unloading rods 3 thereon are in the open state, distributed on both sides of the workpiece. The spacing between the movable clamping jaws 37 and the fixed clamping jaws 31 on the unloading rods 3 is the maximum distance, corresponding to the two ends of the workpiece respectively. When the press 11 completes the punching, the two unloading rods 3 move toward each other and approach the workpiece, thereby clamping the two sides of the workpiece. At the same time, as the unloading rods 3 move, the unloading The movable jaw 37 on the rod 3 will move toward the fixed jaw 31, thereby reducing the distance between the movable jaw 37 and the fixed jaw 31, and clamping the two ends of the workpiece. When the two unloading rods 3 are clamped on both sides of the workpiece, the movable jaw 37 and the fixed jaw 31 clamp the two ends of the workpiece, thereby fixing the workpiece on the unloading mechanism 2. Subsequently, the fixed plate 22 drags the workpiece toward the unloading port 131. When the workpiece moves above the unloading port 131, the two unloading rods 3 start to move in the opposite direction, and the workpiece is finished. The two sides of the workpiece are clamped. At the same time, the movable jaw 37 moves away from the fixed jaw 31, thereby increasing the distance between the movable jaw 37 and the fixed jaw 31, and ending the clamping of the two ends of the workpiece. After the workpiece loses the fixation of the unloading mechanism 2, it will enter the conveying path 13 from the unloading port 131 and fall on the electric conveyor belt 14. The electric conveyor belt 14 thus conveys the workpiece toward the detection component 5. At the same time, the press 11 starts to punch the next plate. The fixed plate 22 pushes the opened unloading rod 3 toward the press 11, returns to the initial state, and waits for the next plate to be punched into a workpiece. When the electric conveyor belt 14 conveys the workpiece toward the detection component 5, the workpiece will first pass under the cleaning component 4, and the rotating cleaning brush 43 cleans the workpiece to prevent the workpiece from affecting the detection of the detection component 5 due to dirt attached to it. Then the electric conveyor belt 14 conveys the cleaned workpiece to the detection component 5 for defect detection to check whether there are defects such as cracks on the surface of the workpiece. After the workpiece is detected, it is discharged from the conveying path 13.

[0021] The difference from the above embodiment is that the unloading mechanism 2 also includes a guide rail 21, which is fixedly mounted on the punching bed 1 and located above the conveying path 13. The fixed plate 22 is slidably mounted on the guide rail 21 through a slider. Two driving racks 221 are fixedly mounted on one end of the fixed plate 22 close to the press 11. The two driving racks 221 are respectively distributed on both sides of the fixed plate 22. Sliding grooves 222 are provided on both sides of the fixed plate 22. The sliding grooves 222 are located on the side of the driving rack 221 away from the press 11. A motor groove 223 is provided on the fixed plate 22, and the motor groove 223 is located between the two sliding grooves 222.

[0022] The difference from the above embodiment is that the unloading mechanism 2 also includes a driving motor 23, which is fixedly installed in the motor slot 223, and the output end of the driving motor 23 is equipped with a bidirectional threaded rod 231, which is rotatably installed in the sliding slot 222, and a driving cylinder 24 is arranged under the fixed plate 22, and the driving cylinder 24 is fixedly installed on the punching bed 1, and the output rod of the driving cylinder 24 is fixedly connected to the end of the fixed plate 22 away from the press 11.

[0023] Among them, the threads at both ends of the bidirectional threaded rod 231 are in opposite directions. When the workpiece needs to be clamped, the driving motor 23 drives the bidirectional screw to rotate in the opposite direction, so that the unloading rod 3 moves towards each other. After the unloading rod 3 clamps and fixes the workpiece, the driving motor 23 stops working, and the driving cylinder 24 extends the output rod, so that the output rod pushes the fixed plate 22 to slide on the guide rail 21, and transports the workpiece to the top of the unloading port 131. At this time, the driving motor 23 drives the bidirectional threaded rod 231 to rotate forward, so that the unloading rod 3 moves in the opposite direction, thereby ending the clamping of the workpiece and putting the workpiece into the unloading port 131. The driving motor 23 stops working again. After completing the placement of the workpiece, the driving cylinder 24 retracts the output rod, so that the output rod drives the fixed plate 22 to slide in the opposite direction on the guide rail 21 and moves back to the side of the press 11.

[0024] The difference from the above embodiment is that the fixed clamp 31 is fixedly connected to the end of the unloading rod 3 away from the fixed plate 22, a displacement groove 32 is provided on the unloading rod 3, the displacement groove 32 is close to the other end of the unloading rod 3, a driving groove 33 is provided at the bottom of the unloading rod 3, the driving groove 33 is located between the displacement groove 32 and the other end of the unloading rod 3, the tooth surface of the driving rack 221 extends into the driving groove 33, and a driving block 34 is fixedly connected to the other end of the unloading rod 3, the driving block 34 is located in the sliding groove 222, and is threadedly engaged with the bidirectional threaded rod 231.

[0025] The difference from the above embodiment is that a driving rod 35 is rotatably installed in the displacement groove 32, and the end of the driving rod 35 away from the fixed clamping jaw 31 passes through the driving groove 33, a thread is provided on the driving rod 35 located in the displacement groove 32, and a driving gear 36 is coaxially fixedly connected to the driving rod 35 located in the driving groove 33, and the driving gear 36 is engaged with the driving rack 221, one end of the movable clamping jaw 37 is slidably installed in the driving groove 33, and the movable clamping jaw 37 is assembled on the threaded section of the driving rod 35 through a thread.

[0026] Among them, when the bidirectional threaded rod 231 rotates in the opposite direction, the driving block 34 in the sliding groove 222 drives the unloading rod 3 to move toward the driving motor 23, thereby clamping the two sides of the workpiece. At the same time, during the movement of the unloading rod 3, the driving rack 221 drives the driving gear 36 to drive the driving rod 35 to rotate forward, so that the driving rod 35 drives the movable clamping jaw 37 to move in the driving groove 33 through the thread, and approaches the fixed clamping jaw 31 to clamp the two ends of the workpiece. When the bidirectional threaded rod 231 rotates forward, the driving block 34 in the sliding groove 222 drives the unloading rod 3 away from the driving motor 23, thereby ending the clamping of the two sides of the workpiece. At the same time, during the movement of the unloading rod 3, the driving rack 221 drives the driving gear 36 to drive the driving rod 35 to rotate in the opposite direction, so that the driving rod 35 drives the movable clamping jaw 37 to move in the driving groove 33 through the thread, away from the fixed clamping jaw 31, thereby ending the clamping of the two ends of the workpiece.

[0027] The difference from the above embodiment is that a stamping die 12 is arranged on the stamping bed 1, the upper die of the stamping die 12 is fixedly connected to the press 11, the lower die of the stamping die 12 is fixedly installed on the stamping bed 1, the conveying path 13 is located at one end of the discharge port 131 and is in a slope shape, the end of the conveying path 13 away from the discharge port 131 is the discharge port 132, a side opening 133 is opened on the side of the conveying path 13, and the side opening 133 is between the detection component 5 and the discharge port 132, and a main pulley 142 is fixedly connected to the first rotating shaft 141 at the end of the electric conveyor belt 14 close to the discharge port 131.

[0028] Among them, when stamping the workpiece, the press 11 lifts the upper die of the stamping die 12. When the plate is placed on the lower die of the stamping die 12, the press 11 pushes the upper die of the stamping die 12 downward to close the stamping die 12 and stamp the plate into a workpiece. After the stamping is completed, the press 11 lifts the upper die of the stamping die 12 again, and the unloading mechanism 2 takes the workpiece away from the stamping die 12. When the workpiece falls into the unloading port 131, the workpiece will slide along the slope of the conveyor path 13 to the electric conveyor belt 14. At this time, the rotating shaft 141 of the electric conveyor belt 14 drives the electric conveyor belt 14 to rotate toward the detection component 5. When the rotating shaft 141 rotates, it will drive the main pulley 142 to rotate synchronously. When the detection component 5 detects that the workpiece has defects, the defective workpiece will be discharged from the conveyor path 13 from the side opening 133, and the workpiece without defects will be discharged from the discharge port 132.

[0029] The difference from the above embodiment is that the cleaning assembly 4 also includes a fixed disk 41, which is fixedly mounted on the top of the conveying path 13, and a rotating shaft 42 is fixedly connected to the top of the cleaning brush 43. The rotating shaft 42 is rotatably mounted on the fixed disk 41, and a worm gear 421 is coaxially fixedly connected to the upper end of the rotating shaft 42 located in the fixed disk 41. A worm 44 is rotatably mounted in the fixed disk 41, and the worm 44 cooperates with the worm gear 421, and one end of the worm 44 penetrates the side wall of the fixed disk 41 and protrudes from the fixed disk 41. The protruding end of the worm 44 A secondary pulley 441 is coaxially fixedly connected to the end, and the secondary pulley 441 is connected to the main pulley 142 through a transmission belt 45. A dust suction head 46 is fixedly connected to the side of the fixed disk 41 close to the detection component 5. The dust suction head 46 extends out of the fixed disk 41 and is located above the cleaning brush 43. The upper end of the dust suction head 46 is fixedly connected to one end of the dust suction pipe 47, and the other end of the dust suction passes through the upper side of the stamping bed 1 and is fixedly connected to the dust suction device 48. The dust suction device 48 is fixedly installed on the stamping bed 1 and is located on the side of the guide rail 21.

[0030] Among them, when the main pulley 142 rotates, the secondary pulley 441 will be driven by the transmission belt 45 to drive the worm 44 to rotate, and the rotating worm 44 will drive the worm wheel 421 to drive the rotating shaft 42 to rotate, so that the rotating shaft 42 drives the cleaning brush 43 to rotate on the workpiece, and the dirt on the workpiece is brushed off. At the same time, the dust suction device 48 is started, and the dust suction head 46 sucks the dirt brushed off by the cleaning brush 43 into the dust suction pipe 47, and discharges it into the dust suction device 48, thereby cleaning the workpiece.

[0031] The difference from the above embodiment is that the detection component 5 includes a fixed seat 51, the upper end of the fixed seat 51 is fixedly connected to the top of the conveying path 13, and the lower end of the fixed seat 51 is fixedly installed with a detection head 52, which is used to detect surface defects of the workpiece.

[0032] The detection head 52 is an industrial camera that detects the workpiece by visual detection.

[0033] The difference from the above embodiment is that a rejecting cylinder 6 is fixedly installed outside the conveying path 13 , and the output shaft of the rejecting cylinder 6 is fixedly connected to a push plate 61 , which corresponds to the side opening 133 .

[0034] When the detection head 52 detects that the workpiece has defects, when the electric conveyor belt 14 conveys the defective workpiece to the side opening 133 , the rejection cylinder 6 pushes the push plate 61 through the output shaft, so that the push plate 61 pushes the defective workpiece out of the side opening 133 .

[0035] Embodiment 2 The difference from the above embodiment is that a sliding door 15 is slidably installed on the side of the punching bed 1 , the position of the sliding door 15 corresponds to the side opening 133 , and a collection frame 7 is placed inside the sliding door 15 , and the collection frame 7 corresponds to the bottom of the side opening 133 .

[0036] Among them, the defective workpieces discharged from the side opening 133 will fall into the collection frame 7, and the defective workpieces will be collected by the collection frame 7. When the defective workpieces in the collection frame 7 need to be emptied, the sliding door 15 is opened, the collection frame 7 is taken out, and then the empty collection frame 7 is put back into the stamping bed 1 and the sliding door 15 is closed.

[0037] Working principle: When in use, the press 11 first lifts the upper die of the stamping die 12. When the sheet is placed on the lower die of the stamping die 12, the press 11 pushes the upper die of the stamping die 12 downward to close the stamping die 12 and stamp the sheet into a workpiece. After the stamping is completed, the press 11 lifts the upper die of the stamping die 12 again. At this time, the fixed plate 22 is close to the press 11 in the initial state, and the unloading rods 3 thereon are in the open state, distributed on both sides of the workpiece, and the distance between the movable clamping jaw 37 on the unloading rod 3 and the fixed clamping jaw 31 is the maximum distance. They correspond to the two ends of the workpiece respectively. When the press machine 11 lifts the upper die of the stamping die 12, the driving motor 23 drives the bidirectional screw to rotate in the opposite direction, and the driving block 34 in the sliding groove 222 drives the unloading rod 3 to move toward the driving motor 23, so as to clamp the two sides of the workpiece. At the same time, during the movement of the unloading rod 3, the driving rack 221 drives the driving gear 36 to drive the driving rod 35 to rotate forward, so that the driving rod 35 drives the movable clamping jaw 37 to move in the driving groove 33 through the thread, and approaches the fixed clamping jaw 31 to clamp the two ends of the workpiece. When the two unloading rods 3 are clamped on both sides of the workpiece, the movable clamping jaws 37 and the fixed clamping jaws 31 clamp the two ends of the workpiece, thereby fixing the workpiece on the unloading mechanism 2. At this time, the driving motor 23 stops working, and then the driving cylinder 24 extends the output rod, so that the output rod pushes the fixed plate 22 to slide on the guide rail 21, and the workpiece is transported to the top of the unloading port 131. The driving motor 23 drives the bidirectional threaded rod 231 to rotate forward, and the driving block 34 in the sliding groove 222 drives the unloading rod 3 away from the driving motor 23, thereby ending the clamping of the two sides of the workpiece. At the same time, during the movement of the unloading rod 3, the driving rack 22 The driving gear 36 drives the driving rod 35 to rotate in the opposite direction, so that the driving rod 35 drives the movable clamping jaw 37 to move in the driving groove 33 through the thread, away from the fixed clamping jaw 31, and ends the clamping of the two ends of the workpiece. After the workpiece loses the fixation of the unloading mechanism 2, it will enter the conveying path 13 from the unloading port 131 and fall on the electric conveyor belt 14, and the electric conveyor belt 14 will transport the workpiece toward the detection component 5. At the same time, the press 11 starts to punch the next plate, and the fixed plate 22 pushes the opened unloading rod 3 to approach the press 11, returning to the initial state, waiting for the next plate to be punched into a workpiece; When the electric conveyor belt 14 transports the workpiece toward the detection component 5, the rotating shaft 141 of the electric conveyor belt 14 drives the main pulley 142 to rotate, and drives the secondary pulley 441 to drive the worm 44 to rotate through the transmission belt 45. The rotating worm 44 drives the worm wheel 421 to drive the rotating shaft 42 to rotate, so that the rotating shaft 42 drives the cleaning brush 43 to rotate on the workpiece. When the workpiece passes under the cleaning component 4, the rotating cleaning brush 43 cleans the workpiece to prevent the workpiece from being affected by the detection of the detection component 5 due to the dirt attached to it. Then the electric conveyor belt 14 transports the cleaned workpiece to the detection component 5 for defect detection, and checks the workpiece. Whether there are defects such as cracks on the surface of the workpiece, when the detection head 52 detects defects in the workpiece, when the electric conveyor belt 14 conveys the defective workpiece to the side opening 133, the rejection cylinder 6 pushes the push plate 61 through the output shaft, so that the push plate 61 pushes the defective workpiece out of the side opening 133, and the defective workpiece discharged from the side opening 133 will fall into the collecting frame 7, and the defective workpieces will be collected by the collecting frame 7. When the defective workpieces in the collecting frame 7 need to be emptied, the sliding door 15 is opened, the collecting frame 7 is taken out, and then the empty collecting frame 7 is put back into the punching bed 1, and the sliding door 15 is closed, and the intact workpiece is discharged from the discharge port 132.
