For example, "connection" can be a wall-mounted connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.
[0048] refer to Figure 1-8This embodiment provides a fully automatic conductive nail 52 visual inspection machine, which includes a feeding device 1, a cleaning device 2, a visual inspection device 3, and a discharging device 4 arranged sequentially along the transport direction of the workpiece 5. For example... Figure 8 The workpiece 5 includes a main body and two protruding edges 51 extending from the bottom of the workpiece 5 along its width direction. Conductive nails 52 are provided on the protruding edges 51. By sequentially arranging a feeding device 1, a cleaning device 2, a vision inspection device 3, and a discharging device 4 along the transport direction of the workpiece 5, the automated feeding, cleaning, inspection, and sorting of the workpiece 5 are achieved, improving inspection efficiency and accuracy and reducing labor costs.
[0049] like Figure 1 The specific structure of the fully automatic conductive nail 52 visual inspection machine is as follows: the feeding device 1 includes a conveyor belt 11 for transporting the workpiece 5 to the visual inspection device 3. The conveyor belt 11 includes an input end 12 and an output end 13, and the output end 13 is connected to the visual inspection device 3. The cleaning device 2 is installed on the conveyor belt 11, and the cleaning device 2 is located near the input end 12. The conveyor belt 11 transports the workpiece 5 through the cleaning device 2, and the cleaning device 2 cleans the conductive nail 52. The visual inspection device 3 includes a delivery component 31, a camera inspection component 32, and a unloading component 33. The delivery component 31 receives the workpiece 5 transported by the conveyor belt 11 and sends it to the camera for inspection. The location of component 32 is inspected; camera inspection components 32 are provided on both sides of the inspection component 31 along the width direction of the conveyor belt 11; the unloading component 33 is used to unload the inspected workpiece 5 to the unloading device 4; the unloading device 4 includes a first unloading channel 41, a second unloading channel 42 and a switching component 44; the switching component 44 is used to switch between the first unloading channel 41 and the second unloading channel 42; the switching component 44 is electrically connected to the camera inspection component 32; the camera inspection component 32 detects the conductive nail 52 and feeds back to the switching component 44; based on the feedback, the switching component 44 selects to switch between the first unloading channel 41 and the second unloading channel 42 for unloading.
[0050] like Figure 2 The feeding device 1 further includes a guiding device 14, which is located behind the input end 12 of the conveyor belt 11. The guiding device 14 includes two guiding plates 141, which are arranged opposite each other on both sides of the conveyor belt 11 along its width. The gap between the two guiding plates 141 allows the workpiece 5 to pass through. The two guiding plates 141 are used to correct the position of the workpiece 5. When the workpiece 5 is placed on the conveyor belt 11 for transportation, the workpiece 5 enters from the input end 12 of the conveyor belt 11. Guided by the guiding plates 141, the position of the workpiece 5 is adjusted and corrected to avoid positional deviations in subsequent operations.
[0051] There is a gap between the bottom of the guide plate 141 and the conveying surface 111 of the conveyor belt 11. This gap allows the protruding edge 51 to pass through. The gap ensures that the main body of the workpiece 5 can pass smoothly through the gap between the two guide plates 141, and also allows the protruding edge 51 at the bottom of the workpiece 5 to pass through the gap at the bottom of the guide plate 141 without obstruction, thereby preventing the workpiece 5 from getting stuck when passing through the guide device 14.
[0052] The guide plate 141 includes a first inclined surface 142 and a second inclined surface 143, which are disposed at the inlet end of the guide plate 141. The first inclined surface 142 is disposed on the inner side of the guide plate 141, which is the side of the two guide plates 141 facing each other. The second inclined surface 143 is disposed at the bottom of the guide plate 141, and the first inclined surface 142 is connected to the second inclined surface 143.
[0053] The first inclined surface 142 and the second inclined surface 143 guide the workpiece 5 smoothly into the gap between the two guide plates 141. When the workpiece 5 approaches the guiding device 14, the first inclined surface 142 gradually guides the main body of the workpiece 5 to the correct position between the two guide plates 141, while the second inclined surface 143 guides the protruding edge 51 at the bottom of the workpiece 5 smoothly through the gap at the bottom of the guide plates 141. Through the guidance of the first inclined surface 142 and the second inclined surface 143, the position of the workpiece 5 can be effectively corrected before it enters the conveyor belt 11 for transportation.
[0054] like Figure 3 The cleaning device 2 has the following specific structure: it includes a fixed frame 21 arranged on both sides of the conveyor belt 11 along the width direction, and a brush 22 installed on the fixed frame 21. The fixed frame 21 serves to support and fix the brush 22. The height of the fixed frame 21 can be adjusted according to the height of the conveying surface 111 of the conveyor belt 11 to accommodate workpieces 5 of different heights.
[0055] The brush head 23 of the brush 22 is suspended above the conveyor surface 111 of the conveyor belt 11; the brush head 23 is used to clean the conductive nails 52 on the workpiece 5. The brush head 23 of the brush 22 is made of a soft and elastic material, such as nylon or animal hair, which can effectively clean impurities without damaging the surface of the workpiece 5 and the conductive nails 52.
[0056] The cleaning process is as follows: when workpiece 5 is transported via conveyor belt 11, the conductive nails 52 on workpiece 5 pass through the brush head 23 of brush 22. The bristles of brush 22 contact the surface of the conductive nails 52, and the impurities and dust on the surface of the conductive nails 52 are cleaned away through the friction of the bristles. The cleaning device 2 cleans the impurities and dust on the surface of the conductive nails 52, ensuring that the camera detection component 32 can clearly capture the surface of the conductive nails 52, thereby improving the accuracy of the detection.
[0057] like Figure 4 The specific structure of the inspection component 31 is as follows: the inspection component 31 includes an inspection plate 311, an inspection fixture 312, and a lifting cylinder 313. The inspection plate 311 is connected to the output end 13 of the conveyor belt 11 and is used to receive the workpiece 5. The camera detection component 32 is arranged vertically above the inspection plate 311. The workpiece 5 is pushed to the inspection plate 311 by the conveyor belt 11, and pushes the previous workpiece 5 placed on the inspection plate 311 to the inspection fixture 312. The lifting cylinder 313 vertically drives the inspection fixture 312 to have a first position 314 and a second position 315. When the inspection fixture 312 is in the first position 314, the workpiece 5 is fed from the inspection plate 311 to the inspection fixture 312. When the inspection fixture 312 is in the second position 315, the camera detection component 32 detects the conductive nails 52 on the workpiece 5.
[0058] The inspection plate 311 is connected to the output end 13 of the conveyor belt 11 and is used to receive the workpiece 5 conveyed from the conveyor belt 11. The surface of the inspection plate 311 is flat and smooth to reduce the friction of the workpiece 5 during the pushing process. The size of the inspection plate 311 should be designed according to the size of the workpiece 5 to ensure that the workpiece 5 can be stably placed on the inspection plate 311.
[0059] like Figure 5 The inspection component 31 further includes a photoelectric sensor 316, which is disposed opposite to the inspection plate 311 on both sides of the inspection fixture 312. When the inspection fixture 312 is in the first position 314, the photoelectric sensor 316 is used to detect the placement of the workpiece 5 on the inspection fixture 312. The photoelectric sensor 316 is electrically connected to the lifting cylinder 313 to realize automated detection and control, thereby improving the operating efficiency and reliability of the equipment.
[0060] The inspection operation is as follows: when the inspection fixture 312 is in the first position 314, the workpiece 5 is pushed from the inspection plate 311 onto the inspection fixture 312. A photoelectric sensor detects whether workpiece 5 is placed on the inspection fixture 312. If the photoelectric sensor 316 detects that workpiece 5 is already placed on the inspection fixture 312, it sends a signal to the lifting cylinder 313, instructing the lifting cylinder 313 to drive the inspection fixture 312 to the second position 315 for inspection. If the photoelectric sensor 316 does not detect workpiece 5, the lifting cylinder 313 will not move, and the inspection fixture 312 will remain in the first position 314, waiting for the next workpiece 5 to be pushed.
[0061] like Figure 4 The unloading assembly 33 is disposed above the inspection plate 311. The unloading assembly 33 includes a pusher cylinder 331. When the inspection fixture 312 is in the second position 315, the inspection fixture 312 corresponds to the position of the discharge device 4. The pusher cylinder 331 pushes the workpiece 5 toward the discharge device 4 so that the workpiece 5 falls into the discharge device 4.
[0062] The pusher cylinder 331 is the main power source of the unloading assembly 33. Its cylinder body is fixed on the bracket above the inspection plate 311, and the piston rod faces the discharge device 4. The extension and retraction of the piston rod are controlled by the air source, providing fast and stable pushing capability. When the inspection fixture 312 is in the second position 315, after the workpiece 5 has completed inspection on the inspection fixture 312, the inspection fixture 312 remains in the second position 315, corresponding to the position of the discharge device 4. The piston rod of the pusher cylinder 331 extends to push the workpiece 5 from the inspection fixture 312 to the inlet 43 of the discharge device 4. After the workpiece 5 is pushed to the discharge device 4, the piston rod of the pusher cylinder 331 retracts to the initial position, ready for the next pushing operation.
[0063] like Figure 6 The specific structure of the feeding component 33 is as follows: the inlet 43 of the first discharge channel 41 and the second discharge channel 42 intersect to form a herringbone-shaped discharge channel; a switching component 44 is provided at the intersection of the first discharge channel 41 and the second discharge channel 42; the switching component 44 switches the inlet 43 to connect with the first discharge channel 41 or the second discharge channel 42.
[0064] The inlet 43 of the first discharge channel 41 and the second discharge channel 42 intersect, and the two discharge channels share a single inlet 43 at the intersection, reducing the space occupied by the equipment and simplifying the unloading path of the workpiece 5. A switching component 44 is provided at the intersection of the first discharge channel 41 and the second discharge channel 42 to control the workpiece 5 to enter different discharge channels. The switching component 44 is electrically connected to the camera detection component 32 and can quickly switch the discharge channel according to the detection result.
[0065] The inspected workpiece 5 is pushed to the inlet 43 by the pusher cylinder 331. The switching component 44 quickly switches the connection status between the inlet 43 and the first discharge channel 41 or the second discharge channel 42 based on the feedback signal from the camera detection component 32. The workpiece 5 enters the corresponding discharge channel according to the inspection result, realizing classified unloading. For example, qualified products enter the first discharge channel 41, and unqualified products enter the second discharge channel 42.
[0066] like Figure 6-7 The specific structure of the switching component 44 is as follows: the switching component 44 includes a baffle plate 441, a telescopic cylinder 442, and a reversing component 443. The baffle plate 441 includes a rotating shaft 4411. The reversing component 443 is connected to the rotating shaft 4411 and the telescopic cylinder 442 respectively. The telescopic cylinder 442 extends and retracts and drives the rotating shaft 4411 to rotate through the reversing component 443, so that the rotating shaft 4411 rotates. The rotation of the rotating shaft 4411 causes the baffle plate 441 to swing in the channel to achieve switching.
[0067] like Figure 7 The reversing component 443 includes a connecting rod 4431 and a first limiting block 4432 and a second limiting block 4433 disposed on both sides of the connecting rod 4431. The two ends of the connecting rod 4431 are respectively connected to the rotating shaft 4411 and the telescopic cylinder 442. The first limiting block 4432 and the second limiting block 4433 are respectively disposed at the bottom of the first discharge channel 41 and the second discharge channel 42. The first limiting block 4432 and the second limiting block 4433 are used to limit the swing range of the connecting rod 4431 to ensure that the baffle plate 441 can be accurately switched to the target position.
[0068] The telescopic cylinder 442 extends and retracts, causing the connecting rod 4431 to swing. The connecting rod 4431 drives the baffle plate 441 to swing through the rotating shaft 4411. When the connecting rod 4431 swings to abut against the first limiting block 4432 or the second limiting block 4433, the baffle plate 441 switches the feed inlet 43 to connect with the first discharge channel 41 or the second discharge channel 42.
[0069] The switching component 44, through the cooperation of the telescopic cylinder 442 and the reversing component 443, can quickly and accurately switch the discharge channel, ensuring that the workpiece 5 enters the corresponding discharge channel according to the detection results, thus realizing classified material discharge.
[0070] The above description is only a preferred embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model by those skilled in the art within the scope of the technology disclosed in the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
