[0043] In order to explain the technical content and structural features of the present invention in detail, the following is a further description in conjunction with the embodiments and the accompanying drawings.

[0044] See also Figure 1 The present invention provides a shrapnel inspection device 1000, comprising a flexible loading device 100, a conveying and reflowing device 200, a visual inspection mechanism, an inspection device 300, and a discharge device 400, all mounted on a frame. The flexible loading device 100 is used for flexible discharge of shrapnel 1001. The flexible loading device 100 includes an inspection camera 30 and an adjustment jig 40. The inspection camera 30 is used to identify the discharge state of the shrapnel 1001 so as to place shrapnel 1001 in the same state on the same area of ​​the adjustment jig 40, so that all shrapnel 1001 arriving at the conveying and reflowing device 200 are in the same state. The conveying and reflowing device 200 is used to convey the shrapnel 1001. The visual inspection mechanism is used to inspect the appearance of the shrapnel 1001. The inspection device 300 is used to inspect the size of the shrapnel 1001. The discharge device 400 is used to convey qualified shrapnel 1001 to the next process or to transfer unqualified shrapnel 1001 out of the discharge device 400.

[0045] After adopting the above technical solution, the shrapnel detection equipment 1000 of the present invention includes a flexible loading device 100 for flexible loading, a conveying and reflowing device 200 for conveying workpieces and reflowing the flow-pulling jig 215, a visual inspection mechanism for visual appearance inspection, a detection device 300 for visual and dimensional inspection, and a discharge device 400 for discharging. The use of flexible loading can avoid damaging the shrapnel 1001. A detection camera 30 and an adjustment jig 40 are also provided on the flexible loading device 100. Since the shrapnel 1001 will have three situations when discharging, namely, side A, side B, and standing, and subsequent inspections require the state of the shrapnel 1001 to be consistent, so as to facilitate better inspection. A detection camera 30 is provided to capture the state of the shrapnel 1001 when discharging, and an adjustment jig 40 is provided. The shrapnel 1001 can be adjusted to the same state by adjusting the rotation of the jig 40 to facilitate subsequent inspection. After being inspected by the visual inspection mechanism and the inspection device 300, the shrapnel 1001 is discharged by the unloading device 400 and any defective parts are recovered. The shrapnel inspection device 1000 of the present invention has a rational structure, achieves consistent workpiece transport, automatically transports and positions the workpiece, and automatically inspects the workpiece, effectively improving automation, inspection efficiency, and accuracy.

[0046] See also Figure 2 and Figure 3In some optional embodiments, the flexible feeding device 100 further comprises a flexible vibration disc 10 and a first picking mechanism 20, and the detection camera 30 is located above the flexible vibration disc 10 to detect the state of each bullet 1001 in the flexible vibration disc 10. When the bullets 1001 are discharged from the flexible vibration disc 10, there are three cases of A face, B face and standing. The state of each bullet 1001 can be determined by the capture of the detection camera 30. There is a first picking mechanism 20 on each side of the flexible vibration disc 10, and each first picking mechanism 20 is used to pick up the bullets 1001 in the corresponding area of the vibration disc. When the detection camera 30 detects that there are more bullets 1001 with A face in the corresponding area, the corresponding first picking mechanism 20 only picks up the bullets 1001 with A face in the area and places them in the corresponding discharging mechanism 401. When the detection camera 30 detects that there are more bullets 1001 with B face in the corresponding area, the corresponding first picking mechanism 20 only picks up the bullets 1001 with B face in the area and places them in the corresponding discharging mechanism 401. When it is detected that there are more bullets 1001 standing, no picking is performed, and the bullets are discharged by vibration again. On the other hand, the adjustment jig 40 comprises a plurality of discharging mechanisms 401 that rotate, and the first picking mechanism 20 places the bullets 1001 with the same state in the same discharging mechanism 401. Before the bullets 1001 are discharged, the discharging mechanisms 401 rotate clockwise / counter-clockwise according to the A face or B face of the bullets 1001, so that when the first picking mechanism 20 discharges the bullets 1001 on the discharging mechanisms 401 and the discharging mechanisms 401 return to the original position, the state of all the bullets 1001 is consistent. That is, after the plurality of discharging mechanisms 401 return to the original position, the bullets 1001 on the adjustment jig 40 are all in the same state.

[0047] Please refer to Figure 3 and Figure 4In some optional embodiments, each discharge mechanism 401 is provided with a rotating assembly and a positioning assembly connected to the rotating assembly. The discharge mechanism 401 is slidably arranged on the base of the adjustment jig 40 through a first sliding assembly 47. The rotating assembly includes a first power member 41, a first support seat 42, a second support seat 43 and a rotating shaft 44. The rotating shaft 44 is located between the first support seat 42 and the second support seat 43 and is located at the output end of the first power member 41. A plurality of discharge members 46 are inserted through the rotating shaft 44. The first power member 41 is actuated to cause the rotating shaft 44 to drive the plurality of discharge members 46 to rotate. The other end of the rotating shaft 44 is connected to the second power member 45. The second power member 45 is actuated to enable the spring piece 1001 to be placed on the discharge member 46, or to complete the positioning of the spring piece 1001 on the discharge member 46. Specifically, each discharge member 46 includes a first discharge portion 461 and a second discharge portion 462 disposed opposite each other. A first magnetic member 463 is provided on each of the first discharge portion 461 and the second discharge portion 462. The rotating assembly operates to position the spring piece 1001 on the first discharge portion 461 or the second discharge portion 462. The discharge member 46 is also provided with a buffering and limiting assembly 464. When the spring piece 1001 is placed on the first discharge portion 461 or the second discharge portion 462, the first magnetic member 463 adsorbs and secures the spring piece 1001. The second power member 45 operates to engage the buffering and limiting assembly 464 with the spring piece 1001 to complete the positioning of the spring piece 1001 on the discharge mechanism 401.

[0048] See also Figure 5 and Figure 6In some optional embodiments, a second picking mechanism 50 is provided at one end of the conveying and reflowing device 200, and the second picking mechanism 50 is used to place the spring piece 1001 on the adjustment jig 40 on the conveying and reflowing device 200. The second picking mechanism 50 is installed on the frame through a support seat and is close to the conveying and reflowing device 200. Specifically, the second picking mechanism 50 includes a plurality of picking components 51 and a fixed seat for fixing the plurality of picking components 51. Each picking component 51 is slidably arranged on the fixed seat, and the picking component 51 can be lifted and slid along the fixed seat to pick up and discharge materials. The picking component 51 includes a positioning block 511 for positioning and movable clamping jaws 512 located on both sides of the positioning block 511, and the clamping jaws 512 are movable to cooperate with the positioning block 511 to pick up and place the spring piece 1001. Since the workpiece to be clamped is a spring sheet 1001, which is in a figure-eight shape, the legs on both sides of the spring sheet 1001 have a certain range of elastic movement. Clamping with the clamping jaws 512 alone would cause certain inconveniences when retrieving the material. Therefore, a positioning block 511 is provided in the retrieving assembly 51, which can extend into the spring sheet 1001. The clamping jaws 512 on both sides cooperate with the central positioning block 511 to clamp the spring sheet 1001. The positioning block 511 is provided with a protruding limiter, and the clamping jaws 512 on both sides are opened to allow the positioning block 511 to extend into the spring sheet 1001. Limiters protrude from both sides of the positioning block 511 to limit the upward and downward movement of the spring sheet 1001. The limiters contact the spring sheet 1001, and the clamping jaws 512 on both sides of the positioning block 511 then clamp the spring sheet 1001, allowing the spring sheet 1001 to be securely clamped.

[0049] See also Figure 7 and Figure 8In some optional embodiments, the conveying and reflowing device 200 includes a conveying and reflowing mechanism 210 located at the starting end, and a conveying line 230, a reflow line 220, and a detection line 240 connected to the conveying and reflowing mechanism 210. A flow-pulling jig 215 for placing the spring pieces 1001 is provided on the conveying line 230, and the reflow line 220 is used for reflowing the flow-pulling jig 215. The conveying and reflowing mechanism 210 includes a first cylinder 211, a first docking portion 212 connected to the conveying line 230, a second cylinder 213, a second docking portion 214 connected to the reflow line 220, and the flow-pulling jig 215. The flow-pulling jig 215 is placed on the first docking portion 212, and the second material picking mechanism 50 picks up the spring pieces 1001 on the adjustment jig 40 and places them on the flow-pulling jig 215. The flow-pulling jig 215 is provided with a second magnetic part 2151 for adsorbing the workpiece, and an avoidance portion 2152 is provided at the location where the spring piece 1001 is placed. The avoidance portion 2152 enables the second material-picking mechanism 50 to better place the spring piece 1001 when picking it up and placing it on the flow-pulling jig 215, without causing interference between the second material-picking mechanism 50 and the flow-pulling jig 215. Specifically, the flow-pulling jig 215 on the first docking portion 212 is pushed onto the conveyor line 230 by the first cylinder 211, and the spring piece 1001 on the conveyor line 230 is the spring piece 1001 to be inspected. A visual inspection mechanism is provided on one side of the conveyor line 230, and the spring piece 1001 on the conveyor line 230 is manually or automatically picked up and placed on the visual inspection mechanism for appearance and dirt inspection. The visual inspection mechanism can be manual inspection using visual tools or automatic inspection equipment. Qualified spring pieces 1001 are pre-positioned at the pre-positioning mechanism 311 for flow into the next process for inspection. Unqualified spring pieces 1001 are recycled. The flow jig 215 on the transmission line is propelled near the pre-positioning mechanism 311 to the return line 220 for recirculation. When the flow jig 215 returns to the second docking station 214, it is pushed by the second cylinder 213 to the first docking station 212 for placement of the spring piece 1001. This cycle repeats itself continuously.

[0050] See also Figure 9 and Figure 10In some optional embodiments, the detection device 300 includes a turntable 1002 located on a frame. A loading mechanism 310, a first detection mechanism 320, a second detection mechanism 330, and a unloading mechanism 340 are arranged sequentially along the circumference of the turntable 1002 along its rotation direction. A plurality of positioning mechanisms 350 for unloading are provided along the circumference of the turntable 1002.

A pre-positioning mechanism 311 for pre-positioning the spring piece 1001 is also provided on the frame near the loading mechanism 310. The pre-positioning mechanism 311 is used to pre-position the spring piece 1001. After the spring piece 1001 is pre-positioned by the pre-positioning mechanism 311, the loading mechanism 310 picks up the spring piece 1001 at a specific position on the pre-positioning mechanism 311, enabling more precise placement of the spring piece 1001 on the positioning mechanism 350. The specific position on the pre-positioning mechanism 311 is where the spring piece 1001 is discharged. The loading mechanism 310 is used to pick up the spring piece 1001 from the pre-positioning mechanism 311 and place it on the positioning mechanism 350. The first detection mechanism 320 is used to detect the dimensions of the first surface of the spring piece 1001, the second detection mechanism 330 is used to detect the dimensions of the second surface of the spring piece 1001, and the unloading mechanism 340 is used to unload the inspected spring piece 1001.

A third magnetic member 3111 for adsorbing the spring clip 1001 is provided on the pre-positioning station. The number of the third magnetic members 3111 can be three, so as to adsorb the head and two legs of the spring clip 1001, making the adsorption more secure. A limiting member 3112 is also provided on the pre-positioning station. The spring clip 1001 cooperates with the third magnetic member 3111 and abuts against the limiting member 3112, so that the spring clip 1001 can be accurately pre-positioned at the pre-positioning station. A sensor 3113 for detecting whether there is a workpiece is also provided on the pre-positioning mechanism 311 , and the sensor 3113 is used to determine whether there is a spring piece 1001 on the corresponding pre-positioning station.

The first pushing member 3522 and the second pushing member 3523 are respectively provided with pushing inclined surfaces that cooperate with the first rolling member 3516 and the second rolling member 3517. The fourth cylinder 3521 is actuated so that the pushing inclined surface on the first pushing member 3522 acts on the first rolling member 3516, the pushing inclined surface on the second pushing member 3523 acts on the second rolling member 3517, and the pushing member 3524 acts on the push block 3518. This causes the first clamping assembly 3511 and the second clamping assembly 3512 on the positioning fixture 351 to move away from each other, and the pressing assembly 3514 is lifted upward, so that the spring 1001 on the storage member 3510 can be removed. Alternatively, the fourth cylinder 3521 is actuated to move the first pushing member 3522 away from the first rolling member 3516, the second pushing member 3523 away from the second rolling member 3517, and the pushing member 3524 away from the push block 3518. This causes the first clamping assembly 3511 and the second clamping assembly 3512 on the positioning fixture 351 to approach each other to clamp the spring piece 1001 horizontally, while the pressing member moves downward to press the spring piece 1001, thereby restricting the movement of the spring piece 1001 in the horizontal and vertical directions, allowing the spring piece 1001 to be securely placed on the storage member 3510. It is understood that the action of a single power assembly 352 can simultaneously act on the first clamping assembly 3511, the second clamping assembly 3512, and the pressing assembly 3514.

[0054] See also Figures 12 to 15In the embodiment, the first material clamping assembly 3511 and the second material clamping assembly 3512 are symmetrically arranged on two sides of the article 3510. The first material clamping assembly 3511 and the second material clamping assembly 3512 are slidably arranged on the mounting plate through the slide rail. The first material clamping assembly 3511 comprises a first clamping piece for clamping the workpiece, the second material clamping assembly 3512 comprises a second clamping piece for clamping the workpiece, and the first fixed block and the second fixed block are further arranged on the mounting plate, the first fixed block is close to the first clamping piece, and the second fixed block is close to the second clamping piece. The first buffer piece is arranged between the first fixed block and the first clamping piece, and the second buffer piece is arranged between the second fixed block and the second clamping piece. The first buffer piece and the second buffer piece can be spring structures. The first buffer piece and the second buffer piece are arranged, when the power assembly 352 moves away from the positioning jig 351, the first buffer piece and the second buffer piece can drive the first clamping piece and the second clamping piece to slowly reset to clamp the elastic sheet 1001 after the elastic sheet 1001 is placed. On the other hand, the elastic piece for driving the material pressing piece to reset is also arranged on the push block 3518, and the material pressing piece can also be reset under the action of the elastic piece to press the elastic sheet 1001 when the power assembly 352 moves away from the positioning jig 351. The arrangement of the first buffer piece, the second buffer piece and the elastic piece can also avoid damaging the elastic sheet 1001.

[0055] Please refer to Figures 12 to 15 In some optional embodiments, the first positioning assembly 3513 linked with the first material clamping assembly 3511 and the second material clamping assembly 3512 is further arranged on the article 3510. When the first material clamping assembly 3511 and the second material clamping assembly 3512 clamp the elastic sheet 1001, the first positioning assembly 3513 penetrates through the first material clamping assembly 3511 and the second material clamping assembly 3512 to limit the movement of the elastic sheet 1001 in the first direction. When the first material clamping assembly 3511 and the second material clamping assembly 3512 move away from each other, the first positioning assembly 3513 is separated from the elastic sheet 1001. Specifically, the first positioning assembly 3513 can be connected to the first material clamping assembly 3511 or the second material clamping assembly 3512, so as to drive the first positioning assembly 3513 to act when the first material clamping assembly 3511 and the second material clamping assembly 3512 act. The first positioning assembly 3513 comprises a first positioning piece capable of cooperating with the groove on the elastic sheet 1001 and a magnetic piece for adsorbing and fixing the first positioning piece. The magnetic piece is arranged to enable the first positioning piece to cooperate with the elastic sheet 1001 more stably.

[0056] Please refer to Figures 12 to 15In some optional embodiments, the positioning jig 351 is further provided with a second positioning assembly 3515 for positioning. The second positioning assembly 3515 is slidably mounted on the positioning jig 351. Furthermore, the feeding mechanism 310 includes a first toggle assembly 312 for driving the second positioning assembly 3515. The first toggle assembly 312 acts on the second positioning assembly 3515 to slide the second positioning assembly 3515 into position within the spring 1001. Specifically, the second positioning assembly 3515 includes a second positioning member, a toggle block connected to the second positioning member, and a guide rail assembly. The second positioning member is mounted on the mounting plate via the guide rail assembly, with the toggle block protruding above the second positioning member. The first toggle assembly 312 includes a toggle block 3121 that cooperates with the toggle block. Actuation of the power element on the first toggle assembly 312 causes the toggle block 3121 to act on the toggle block, thereby driving the second positioning member to slide between the two legs of the spring 1001, thereby restricting the forward and backward movement of the spring 1001. Through the cooperation of the first clamping assembly 3511 , the second clamping assembly 3512 , the first positioning assembly 3513 , the pressing assembly 3514 and the second positioning assembly 3515 , the spring piece 1001 is stably placed on the storage piece 3510 .

[0057] See also Figure 16 In some optional embodiments, the first inspection mechanism 320 includes a first camera inspection assembly 321 and a first light source assembly 322 for inspection. The first camera inspection assembly 321 is located at the top of the turntable 1002, and the first light source assembly 322 is located at the bottom of the turntable 1002. The first camera inspection assembly 321 and the first light source assembly 322 cooperate to inspect the appearance and dimensions of the first surface of the spring clip 1001 on the positioning fixture 351 of the turntable 1002. When the first inspection mechanism 320 inspects the spring clip 1001, the spring clip 1001 is in a clamped state.

[0058] See also Figure 17In some optional embodiments, the second detection mechanism 330 comprises a second camera detection assembly 331 for detection, a second light source assembly 332, and a second poking assembly 334 for poking the positioning mechanism 350. The second camera detection assembly 331 is located at the bottom of the turntable 1002, and the second light source assembly 332 and the second poking assembly 334 are located at the top of the turntable 1002. The second camera detection assembly 331 cooperates with the second light source assembly 332 to detect the appearance and size of the second surface of the spring 1001 on the positioning jig 351 of the turntable 1002. When the second detection mechanism 330 detects the spring 1001, the spring 1001 is in a released state. The second poking assembly 334 is used to poke the poking block to make the second positioning member exit the spring 1001, so that the second detection mechanism 330 can well detect the appearance and size of the second surface of the spring 1001. Since the second camera detection assembly 331 for detection is located at the bottom of the turntable 1002, the lens faces upward and is easy to accumulate dust, thereby affecting the detection effect. Therefore, a cleaning assembly 333 for blowing cleaning is arranged near the second camera detection assembly 331 to blow and clean the lens of the second camera detection assembly 331 before detection, so as to ensure that there is no dust on the second camera detection assembly 331, thereby not affecting the detection effect.

[0059] Referring to Figure 18 In some optional embodiments, the blanking mechanism 340 comprises a dust removal structure located on the rack, and the dust removal structure comprises a blowing assembly 341 and a suction assembly 342. The blowing assembly 341 and the suction assembly 342 are oppositely arranged. The third taking mechanism 410 takes the spring 1001 after the spring 1001 passes through the dust removal structure. The blowing assembly 341 comprises a blowing member for blowing, and the suction assembly 342 is used to adsorb the dust on the spring 1001. The spring 1001 is cleaned by the blowing assembly 341 and the suction assembly 342, and then taken by the third taking mechanism 410.

[0060] Referring to Figure 19 and Figure 20In some optional embodiments, the unloading device 400 includes a third retrieving mechanism 410, a tray conveyor mechanism 420, and an unloading mechanism 430. The third retrieving mechanism 410 picks up the spring fragments 1001 that have completed inspection on the inspection device 300 and places them on the tray conveyor mechanism 420 or the unloading mechanism 430. The third retrieving mechanism 410 has a similar structure to the second retrieving mechanism 50, both being equipped with multiple retrieving assemblies 51 for retrieving the spring fragments. After inspection by the first inspection mechanism 320 and the second inspection mechanism 330, the spring fragments 1001 are transferred to the unloading mechanism 340. Qualified spring fragments 1001 are cleaned in the unloading mechanism 340 and then picked up by the third retrieving mechanism 410 and transferred to the tray conveyor mechanism 420 for the next process step. Unqualified spring fragments 1001 are directly picked up by the third retrieving mechanism 410 and placed on the unloading mechanism 430. The NG mechanism 430 includes an NG material tray 431 slidably disposed on a third sliding assembly 432 . There may be multiple NG material trays 431 for alternate operation.

[0061] like Figures 1 to 20 As shown, the shrapnel detection equipment 1000 of the present invention includes a flexible loading device 100 for flexible loading, a conveying and reflowing device 200 for conveying workpieces and reflowing the flow-pulling jig 215, a visual inspection mechanism for visual appearance inspection, an inspection device 300 for visual and dimensional inspection, and a discharge device 400 for discharging. The use of flexible loading can avoid damaging the shrapnel 1001. A detection camera 30 and an adjustment jig 40 are also provided on the flexible loading device 100. Since the shrapnel 1001 will have three situations when discharging, namely, side A, side B, and standing, and subsequent inspections require the state of the shrapnel 1001 to be consistent, so as to facilitate better inspection. A detection camera 30 is provided to capture the state of the shrapnel 1001 when discharging, and an adjustment jig 40 is provided. The shrapnel 1001 can be adjusted to the same state by adjusting the rotation of the jig 40 to facilitate subsequent inspection. After being inspected by the visual inspection mechanism and the inspection device 300, the shrapnel 1001 is discharged by the unloading device 400 and any defective parts are recovered. The shrapnel inspection device 1000 of the present invention has a rational structure, achieves consistent workpiece transport, automatically transports and positions the workpiece, and automatically inspects the workpiece, effectively improving automation, inspection efficiency, and accuracy.
