The NG product return device 40 transports the bar that does not meet the preset values ​​to the NG product return waiting station 42 for a second re-inspection based on the inspection results. The NG product handling device 50 transports the bar to be re-inspected to the station of the feeding device 10 again to feed the bar to the inspection device 30 for a second round of size and appearance defect inspection. Based on the results of the second round of inspection, it is finally determined whether the bar is an NG product. The bar that is determined to be an NG product is then transported to the NG product collection box 43 with the corresponding size / appearance defect setting, thereby realizing the classification and storage of NG product bars. Meanwhile, the material handling device 60 picks up the qualified bar stock located at the end station 22 and places it on the material tray 61 for sorting. The automatic boxing device 70 can sequentially transport a row of qualified bar stock that has been sorted to the material box 71 for storage, thereby realizing the automatic sorting and boxing of qualified bar stock.

Combined with the function of the NG product return device 40, the defective bar stock is returned, so that the detection device 30 can re-inspect the size and appearance defects of the bar stock. The bar stock without defects (i.e., qualified products) is directly conveyed to the end station 22 of the conveying device 20 to wait for sorting and boxing.

[0088] The detection control module 812 controls the diameter detection module 34 to detect the diameter of the bar located at the diameter detection station 313; the handling control module 811 handles the bar to the chamfering detection station 314 when the diameter of the bar meets the preset value; the NG product return control module 813 controls the NG product return device 40 to handle the bar to the diameter defect NG product collection box 433 set in the diameter defect NG product return station 413 when the diameter detection module 34 detects that the diameter of the bar does not meet the preset value.

[0089] The detection control module 812 controls the chamfer dimension detection module 35 to perform chamfer dimension detection on the bar located at the chamfer dimension detection station 314; when the chamfer dimension of the bar meets the preset value, the handling control module 811 handles the bar to the bar defect detection station 315; when the chamfer dimension detection module 35 detects that the chamfer dimension of the bar does not meet the preset value, the NG product return control module 813 controls the NG product return device 40 to handle the bar to the chamfer dimension defect NG product collection box 434 set in the chamfer dimension defect NG product return station 414.

[0092] As described above, the conveying device 20, the detection device 30, and the NG (Not Good) return device 40 work together to complete the second round of dimensional and appearance defect detection of the bars. Bars without defects (i.e., qualified products) are directly conveyed to the end station 22 of the conveying device 20 to await sorting and boxing. Bars still with defects are classified as NG (Not Good). Simultaneously, the NG return device 40 conveys the NG bars to the corresponding defect collection box, achieving classified storage of bar defects. Bars initially found to have defects are conveyed to the feeding device 10 via the NG return device 40 for re-inspection by the detection device 30. Based on the inspection results, the final NG bars are determined, thus avoiding an increase in the NG rate due to detection errors.

[0093] Please also refer to Figure 6 ,for Figure 3 The diagram shows a three-dimensional structure of the feeding device.

[0094] The feeding device 10 includes: a first bar hopper 111, a second bar hopper 112, a first sliding platform 121, a first servo motor 13, a first material distribution mechanism 14, a clamping device 15, a door opening mechanism 16, a positioning device 17, and a connecting device 18.

[0095] The feeding device 10 is fixed to the side wall of the equipment base 11 by the connecting plate of the connecting device 18.

[0096] The feeding device 10 is pre-set with a waiting station A, a working station B, and a unloading station C.

[0097] The first sliding platform 121 is provided with a first bar hopper 111 and a second bar hopper 112. Corresponding to the first bar hopper 111, a positioning mechanism 1701, clamping components 151 and 152, and a first door opening mechanism 161 are provided. The positioning mechanism 1701 is installed below the first sliding platform 121, pulling the first bar hopper 111 to slide and position itself on the first sliding platform 121. The clamping components 151 and 152, fixed on the first sliding platform 121 and distributed on both sides of the first bar hopper 111, press the first bar hopper 111 firmly onto the first sliding platform 121. Similarly, the positioning mechanism 1702 is installed below the first sliding platform 121, pulling the second bar hopper 112 to slide and position itself on the first sliding platform 121. The clamping components 153 and 154, fixed on the first sliding platform 121 and distributed on both sides of the second bar hopper 112, press the second bar hopper 112 firmly onto the first sliding platform 121.

[0098] The feeding device 10 also includes a first sliding mechanism 122 connected to the first sliding platform 121 and mounted on the connecting device 18. The first bar stock bin 111 and the second bar stock bin 112 are arranged parallel to each other and side-by-side on the first sliding platform 121. The first sliding mechanism 122 can slide in response to the drive of the feeding control module 810, thereby switching the first bar stock bin 111 and the second bar stock bin 112 between the waiting station A, the working station B, and the unloading station C. For example, initially, the first bar stock bin 111 is in the waiting station A, and the second bar stock bin 112 is in the working station B. After all the bars in the second bar stock bin 112 have been inspected, the second bar stock bin 112 moves to the unloading station C, while the first bar stock bin 111 moves to the working station B. At this time, station A becomes the unloading station. An AGV or manual labor removes the empty bar stock bin from the unloading station and then replenishes it with a new full bar stock bin.

[0099] The first bar bin 111 and the second bar bin 112 are respectively provided with a first door opening mechanism 161 and a second door opening mechanism 162 that can open and close the bin doors.

[0100] When the first bar hopper 111 or the second bar hopper 112 is in working position B, the corresponding first door opening mechanism 161 or second door opening mechanism 162 responds to the control of the feeding control module 810 to control the opening and closing of the hopper door of the first bar hopper 111 or the second bar hopper 112 located in working position B.

[0101] The first material distribution mechanism 14 is mounted on the connecting device 18, corresponding to the working station B, and is located adjacent to the front end of the bar stock bin at working station B. The first material distribution mechanism 14 consists of two discs, left and right, with 10 grooves evenly distributed on each disc. When the first door opening mechanism 161 opens the door of the first bar stock bin 111, and the second door opening mechanism 162 opens the door of the second bar stock bin 112, all the bars roll down the inclined surface of the bin and come into contact with the two discs. The first servo motor 13 drives the discs to rotate, thereby hooking the bars into the grooves. Since the grooves are evenly distributed and spaced, intermittent feeding of the bars is achieved.

[0102] The working principle of the feeding device 10 is as follows:

[0103] The feeding control module 810 controls the first sliding mechanism 122 to move the first bar stock bin 111 or the second bar stock bin 112 containing the bar stock from the waiting station A of the first sliding platform 121 to the working station B. Through the combined action of the positioning device 17 and the clamping device 15, the first bar stock bin 111 or the second bar stock bin 112 is positioned and clamped on the working station B. The first door opening mechanism 161 or the second door opening mechanism 162 opens the door of the first bar stock bin 111 or the second bar stock bin 112 in response to the control of the feeding control module 810. The feeding control module 810 also controls the first servo motor 13 to rotate, thereby driving the first dispensing mechanism 14 to rotate and retrieve bar stock from the first bar stock bin 111 or the second bar stock bin 112, and transfer the retrieved bar stock to the conveying component of the starting station 21 of the conveying device 20.

[0104] As described above, the feeding device 10 moves the first bar bin 111 or the second bar bin 112 containing the bar stock from the waiting station A to the working station B and positions it, so that the first door opening mechanism 161 or the second door opening mechanism 162 automatically opens the corresponding first bar bin 111 or second bar bin 112, so that the first dispensing mechanism 14 can obtain the bar stock from the first bar bin 111 or the second bar bin 112 and transport it to the transport component of the transport device 20, thereby completing the automatic feeding of the bar stock, so that the transport device 20 can transport it to the detection device 30 for the detection of the size and appearance defects of the bar stock.

[0105] Please see Figure 7 ,for Figure 3 The diagram shows a three-dimensional structural schematic of the conveying device.

[0106] The conveying device 20 includes: a starting station 21, an ending station 22, an intermittent conveying component 23, a synchronous belt 24, a synchronous pulley 25, and a second servo motor 26.

[0107] The conveying device 20 is disposed on the table surface of the equipment platform 11, and the starting station 21 is disposed on the side of the table surface of the equipment platform 11, close to the side of the feeding device 10; the ending station 22 is disposed on the side of the table surface of the equipment platform 11, and opposite to the side of the table surface where the starting station 21 is disposed.

[0108] The starting station 21 is set near the first material distribution mechanism 14 of the feeding device 10; further, the starting station 21 is set at the beginning of the synchronous belt 24, and the ending station 22 is set at the end of the synchronous belt 24.

[0109] Specifically, the conveying device 20 includes several intermittent conveying components 23, which are installed on the combined splicing plate and driven by the linkage mechanism driven by the synchronous belt 24, thereby realizing intermittent motion; the synchronous pulley 25 is connected to the second servo motor 26, and the synchronous belt 24 is arranged to bypass the synchronous pulley 25.

[0110] The transport control module 811 controls the second servo motor 26 to rotate, thereby driving the synchronous pulley 25 to rotate, so that the synchronous belt 24 can move from the starting station 21 to the end station 22 under the drive of the synchronous pulley 25, thereby driving a number of intermittent transport components 23 distributed on it to move from the starting station 21 to the end station 22.

[0111] Specifically, the working principle of the conveying device 20 is as follows:

[0112] The second servo motor 26 rotates in response to the control of the transport control module 811, thereby driving the synchronous belt 24 to move and move the intermittent transport component 23 located at the starting station 21 toward the ending station 22. Meanwhile, driven by the first servo motor 13, the first material distribution mechanism 14 transfers the bar stock in the disc groove to the intermittent transport component 23 at the starting station 21.

[0113] As described above, the conveying device 20 moves the intermittent conveying component 23 by setting a movable synchronous belt 24 between the starting station 21 and the ending station 22 and moving it under the drive of the second servo motor 26, thereby realizing the conveying of the bar material.

[0114] Please see Figure 8 ,for Figure 3 The diagram shows a three-dimensional structure of the detection device.

[0115] The detection device 30 is disposed on the table surface of the equipment platform 11. Specifically, the length detection station 311, the end face defect detection station 312, the diameter detection station 313, the chamfer size detection station 314, the bar body defect detection station 315, and the chamfer defect detection station 316 are arranged sequentially on the table surface of the equipment platform 11. Among them, the length detection station 311 is disposed near the starting station 21 of the conveying device 20, and the chamfer defect detection station 316 is disposed near the ending station 22 of the conveying device 20.

[0116] Furthermore, corresponding to the length detection station 311, end face defect detection station 312, diameter detection station 313, chamfer size detection station 314, rod body defect detection station 315, and chamfer defect detection station 316, a length detection module 32, an end face defect detection module 33, a diameter detection module 34, a chamfer size detection module 35, a rod body defect detection module 36, and a chamfer defect detection module 37 are respectively provided.

[0117] Specifically, the working principle of the detection device 30 is as follows:

[0118] When the intermittent conveying component 23 of the conveying device 20 moves from the starting station 21 to the ending station 22, it passes through the length detection station 311, end face defect detection station 312, diameter detection station 313, chamfer size detection station 314, rod body defect detection station 315, and chamfer defect detection station 316 of the detection device 30 in sequence.

[0119] When the intermittent transport component 23 moves the bar from the starting station 21 to the length detection station 311, the detection control module 812 controls the length detection module 32 to perform length detection on the bar at the station. If the detection result meets the preset value, the intermittent transport component 23 continues to move the bar towards the end face defect detection station 312. If the detection result does not meet the preset value, the first blocking mechanism 49 is controlled to block the bar moved by the intermittent transport component 23 and cause the bar to roll down to the NG product return waiting station 42 of the NG product return device 40 (which will be described in detail in the corresponding section below).

[0120] Similarly, when the detection result meets the preset value, the transport control module 811 controls the intermittent transport component 23 to move the bar to the next detection station for the next detection; when the detection result does not meet the preset value, it controls the first blocking mechanism 49 to block the bar moved by the intermittent transport component 23 and make the bar roll down to the NG product return waiting station 42 of the NG product return device 40.

[0121] As described above, when the detection result meets the preset value, the handling control module 811 controls the intermittent handling component 23 to move the bar to the next detection station for the next detection. When the detection result does not meet the preset value, the module controls the first blocking mechanism 49 to block the bar moved by the intermittent handling component 23 and make the bar roll down to the NG product return waiting station 42 of the NG product return device 40, thereby automatically realizing the simultaneous detection of multiple parameters of bar size and appearance defects.

[0122] Please see Figure 9 ,for Figure 3The diagram shows a three-dimensional structure of the NG product recirculation device.

[0123] The NG product return device 40 includes: NG product return station 41, NG product return waiting station 42, NG product collection box 43, first motor 44, rotary device 45, second motor 46, main belt 47, branch belt 48, and first blocking mechanism 49.

[0124] The NG product return device 40 is installed on the equipment base 11; wherein, the NG product return waiting station 42, the length defect NG product return station 411, the end face defect NG product return station 412, the diameter defect NG product return station 413, the chamfer size defect NG product return station 414, the bar body defect NG product return station 415, and the chamfer defect NG product return station 416 are distributed on the equipment base 11 in sequence; the length defect NG product return station 411 is located near the starting station 21 of the conveying device 20, and the chamfer defect NG product return station 416 is located near the ending station 22 of the conveying device 20.

[0125] The NG product collection box 43 is respectively set up for the NG product return station 41 mentioned above;

[0126] The first motor 44 is mounted below the equipment base 11 via a connecting plate;

[0127] Rotary device 45 is installed on the platform of the equipment base 11;

[0128] The second motor 46 is installed below the equipment base 11 via a connecting plate;

[0129] A first blocking mechanism 49 is installed below the table surface of the equipment platform 11; wherein, one first blocking mechanism 49 is provided for each NG product return station 41.

[0130] The main belt 47 is located below the equipment platform 11 and extends along the NG product return station 41. It is used to transport the bars that fall from the NG product return station 41 onto the main belt 47 from the corresponding station to the NG product return waiting station 42.

[0131] The belt branch line 48 is located below the equipment platform 11 and is distributed perpendicularly along the direction of the main belt line 47. Specifically, a belt branch line 48 is provided for each return station to transport the bar material that falls on the belt branch line 48 from the current station to the main belt line 47.

[0132] Specifically, the working principle of the NG product return device 40 is as follows:

[0133] When the detection control module 812 initially determines a part to be non-conforming based on the detection results of the detection station, that is, when an NG (Not Good) product is detected, the NG product return control module 813 is used to:

[0134] The first blocking mechanism 49 set at the corresponding transport station is controlled to stop the bar driven by the intermittent transport component 23 and cause the bar to roll onto the corresponding belt branch 48.

[0135] Controlling the first motor 44 to operate to drive the belt branch 48 to transport the bar to the belt main 47; and

[0136] The second motor 46 is controlled to work to drive the main belt 47 to transport the bar to the NG product return waiting station 42.

[0137] When the detection control module 812 determines that the re-inspection result is a defective part based on the detection result of the detection station, that is, when it determines that the product is NG (Not Good), the NG product return control module 813 is used to:

[0138] The first blocking mechanism 49 set at the corresponding transport station is controlled to stop the bar driven by the intermittent transport component 23 and cause the bar to roll onto the corresponding belt branch 48.

[0139] The rotary device 45 is controlled to drive the belt branch line 48 to transport the bar to the corresponding NG product collection box 43.

[0140] As described above, the seven inspection stations are set up adjacent to each other with seven corresponding NG product return channels, which are driven and conveyed by the first motor 44. Under the combined action of the sensor and the rotary device 45, the NG products on the seven belt branch lines 48 fall alternately and orderly onto the main belt line 47, and are driven and conveyed by the second motor 46, flowing back to the NG product return waiting station 42.

[0141] If the control device 80 still determines that the NG product is unqualified after a round of re-inspection, the NG product will be directly returned to the corresponding NG product collection box 43 through the channel of belt branch 48 and rotary device 45, thereby realizing the classified collection of NG products.

[0142] Please see Figure 10 ,for Figure 3 The diagram shows a three-dimensional structure of the NG (Not in the Own Goods) handling device.

[0143] The NG product handling device 50 includes: a re-inspection waiting bin 51, a first handling mechanism 52, a gripper 53, a rotary mechanism 54, a second handling mechanism 55, and a second blocking mechanism 56.

[0144] The NG product handling device 50 is located on the side wall of the equipment platform 11 and close to the feeding device 10.

[0145] The first handling mechanism 52 is mounted on the table surface of the equipment base 11 via a connecting bracket;

[0146] The gripper 53 is fixed below the rotary mechanism 54 via a transition connecting plate;

[0147] The rotary mechanism 54 is fixed on the bracket at the end of the first conveying mechanism 52;

[0148] The second handling mechanism 55 is mounted on the table surface of the equipment base 11 via a transition bracket;

[0149] The second blocking mechanism 56 is fixed below the second conveying mechanism 55 via a transition connecting plate;

[0150] Specifically, the working principle of the NG product handling device 50 is as follows:

[0151] The NG product handling control module 814 controls the gripper 53 to pick up the NG product bar from the NG product return waiting station 42 of the NG product return device 40, and controls the first handling mechanism 52 to move it above the re-inspection waiting hopper 51. It also controls the rotary mechanism 54 to drive the gripper 53 and the NG product to rotate together. Then the gripper 53 is released, allowing the NG product to fall into the re-inspection waiting hopper 51.

[0152] After all the NG products in the first round are collected, the second conveying mechanism 55 moves to move the re-inspection waiting bin 51 (along with the NG products) into the first bar bin 111 or the second bar bin 112 of the feeding device 10. The second blocking mechanism 56 opens, so that all the NG products fall into the first bar bin 111 or the second bar bin 112.

[0153] As described above, the NG product handling device 50 handles and collects the bars that have been identified as NG products in the first round of inspection into the re-inspection waiting bin 51. After the first round of inspection of all bars is completed, the re-inspection waiting bin 51 is transported to the loading bin of the loading device 10, so that the loading device 10 can reload these NG product bars to be re-inspected and transport them to the inspection device 30 for the second round of inspection, thereby realizing the collection of NG product bars and the handling for secondary inspection.

[0154] Please see Figure 11 ,for Figure 3 The diagram shows a three-dimensional structure of the material handling device.

[0155] The material handling device 60 includes: a material tray 61, a second material distribution mechanism 62, a third servo motor 63, a first conveying device 64, a second conveying device 65, and a connecting bracket 66.

[0156] The material handling device 60 is located on the side of the equipment platform 11 and near the end station 22 of the conveying device 20.

[0157] The third servo motor 63 is connected to the second material distribution mechanism 62 via a coupling. The third servo motor 63 can rotate under the control of the material handling control module 815, thereby driving the second material distribution mechanism 62 to rotate synchronously.

[0158] The second material distribution mechanism 62 is supported and fixed by a bearing seat, then installed on the connecting bracket 66, and finally fixed on the table surface of the equipment base 11;

[0159] The material tray 61 is disposed near the second material distribution mechanism 62. A plurality of grooves 610 are distributed on the surface of the material tray 61 to accommodate bars. Specifically, the size of each groove 610 is such that it can accommodate one bar. Further, each groove 610 is an arc-shaped groove, and the plurality of grooves 610 are parallel to each other and arranged side-by-side on the surface of the material tray 61, with the long side of each arc-shaped groove extending perpendicular to the rotation direction of the second material distribution mechanism 62.

[0160] The second conveying device 65 is fixed to the connecting bracket 66 by a transition plate and is located below the material tray 61. It can move along the surface of the material tray 61 in response to the control of the material handling control module 815, and the direction of movement is perpendicular to the extension direction of the long side of the groove 610, thereby pushing the bars rolling on the surface of the material tray 61 into the corresponding grooves 610. The second conveying device 65 pushes the bars into the corresponding grooves 610 in the order in which they roll down, according to the distribution order of the grooves 610 from near to far, and pushes them forward continuously to arrange them in a row on the material tray 61.

[0161] The first conveying device 64 is fixed on the connecting bracket 66 by a transition plate and is set on one side of the material tray 61. It can respond to the control of the material handling control module 815 to push a row of bars into the boxing gripper 73 of the automatic boxing device 70 for automatic boxing.

[0162] Specifically, the working principle of the material handling device 60 is as follows:

[0163] The material handling control module 815 controls the rotation of the third servo motor 63 to drive the second material distribution mechanism 62 to rotate synchronously. Under the drive of the second servo motor 26, the conveying device 20 transfers the bar material on the intermittent conveying component 23 of the end station 22 to the disc groove of the second material distribution mechanism 62, and drives the disc of the second material distribution mechanism 62 to continue rotating so that the bar material can roll onto the material tray 61.

[0164] The second handling device 65 responds to the control of the material handling control module 815 to push the bars that roll onto the material tray 61 into the corresponding grooves 610, so that the multiple bars that roll down one after another are successively accommodated into the corresponding grooves 610, thereby pushing the bars into a row and completing the sorting before boxing.

[0165] When the grooves 610 on the material tray 61 accommodate the required number of bars, the first handling device 64, in response to the control of the material handling control module 815, pushes a row of bars that has been sorted by the second handling device 65 into the boxing gripper 73 of the automatic boxing device 70 for automatic boxing.

[0166] As described above, the material handling device 60, through the cooperation of the second material distribution mechanism 62 and the second conveying device 65, sorts the bars that roll onto the material tray 61 one by one, arranges them neatly on the material tray 61, and then the second conveying device 65 pushes the sorted row of bars into the boxing gripper 73 of the automatic boxing device 70. This reciprocating action realizes the batch feeding of the automatic boxing device 70.

[0167] Please see Figure 12 ,for Figure 3 The diagram shows a three-dimensional structure of the automatic boxing device 70.

[0168] The automatic boxing device 70 includes: a material box 71, a two-axis module 72, a boxing gripper 73, a second sliding platform 74, a rotating mechanism 78, and a connecting plate 79.

[0169] The automatic boxing device 70 is pre-set with a material feeding station 75, a working station 76, and a material waiting station 77.

[0170] The second sliding platform 74 is provided with a material box 71; in this embodiment, the number of material boxes 71 provided is 2, namely a first material box 711 and a second material box 712; the second sliding platform 74 includes a second platform 741 and a second sliding mechanism 742 provided on the second platform 741; the first material box 711 and the second material box 712 are arranged parallel to each other and side by side on the second sliding mechanism 742; the second sliding mechanism 742 can slide in response to the drive of the automatic boxing control module 816, thereby driving the material box 71 to switch between the unloading station 75, the working station 76 and the waiting station 77.

[0171] The dual-axis module 72 includes a Z-axis motion mechanism 721, an X-axis motion mechanism 722, and a support 723. The Z-axis motion mechanism 721 is mounted on the X-axis motion mechanism 722 via a transition plate. In response to the drive of the automatic boxing control module 816, the rotating mechanism 78, together with the boxing gripper 73, reciprocates along the Z-axis direction. The X-axis motion mechanism 722 is mounted on the support 723 via a transition plate. In response to the drive of the automatic boxing control module 816, the Z-axis motion mechanism 721, together with the rotating mechanism 78 and the boxing gripper 73, reciprocates along the X-axis direction.

[0172] The boxing gripper 73 is disposed on the rotating mechanism 78, which is disposed at the free end of the Z-axis motion mechanism 721. Under the drive of the Z-axis motion mechanism 721, the X-axis motion mechanism 722 and the rotating mechanism 78, the boxing gripper 73 can be displaced in the Z-axis and X-axis directions and rotated, thereby pushing the second conveying device 65 of the material handling device 60 into a row of bars in the boxing gripper 73 and conveying them into the material box 71 located on the working station 76.

[0173] Specifically, the working principle of the automatic cartoning device 70 is as follows:

[0174] The automatic boxing control module 816 controls the second sliding mechanism 742 to move the empty material box 71 to the working station 76, and controls the reciprocating motion of the two-axis module 72 and the rotational motion of the rotating mechanism 78 to drive the boxing gripper 73 to push the second conveying device 65 of the material sorting device 60 into a row of bars in the boxing gripper 73, and transport them to the second material box 712 located at the working station 76, thereby realizing the multi-stage and layered boxing of the bars; when the second material box 712 located at the working station 76 is full of bars, the automatic boxing control module 816 also drives the second sliding mechanism 742 to move the second material box 712 from the working station 76 to the unloading station 75, and at the same time moves the empty first material box 711 located at the waiting station 77 to the working station 76, waiting to continue to hold bars.

[0175] As described above, the automatic boxing device 70 can push the second conveying device 65 of the material handling device 60 into a row of bars in the boxing gripper 73 and transport them to the material box 71 located at the working station 76, thereby boxing the qualified bars (which have been sorted by the material handling device 60) in batches and layers.

[0176] This invention also provides an automatic bar detection and packaging control method, which operates in the automatic bar detection and packaging equipment 1 described above. Please refer to [link to relevant documentation]. Figure 13 This is a flowchart illustrating an automatic bar material detection and packaging control method according to the first embodiment of the present invention.

[0177] The automatic detection and packaging control method for bar stock includes the following steps:

[0178] In step S100, the feeding control module 810 controls the feeding device 10 to pick up the bar to be tested and transfer the bar to be tested to the starting station 21 of the conveying device 20.

[0179] In step S110, the handling control module 811 controls the handling device 20 to transport the bar located in the starting station 21 to the detection station of the detection device 30.

[0180] In step S120, the detection control module 812 controls the detection device 30 to perform size and appearance defect detection on the bar located in the detection station, and determines whether the bar meets the preset value based on the detection result; if yes, proceed to step S130; otherwise, proceed to step S160.

[0181] In step S130, the transport control module 811 transports the bar to the end station 22 of the transport device 20.

[0182] In step S140, the material handling control module 815 controls the material handling device 60 to pick up the bar stock located at the end station 22 and put it into the material tray 61, and to sort the bar stock in the material tray 61; and to push the sorted row of bar stock into the boxing gripper of the automatic boxing device 70.

[0183] In step S150, the automatic cartoning control module 816 controls the automatic cartoning device 70 to transport a row of rods from the cartoning gripper to the material box 71 for storage. Then, the process ends.

[0184] In step S160, the detection control module 812 determines whether the number of times the detection result that does not conform to the preset value occurs is greater than n based on the detection result; if so, proceed to step S190; otherwise, proceed to step S170.

[0185] Where n is a natural number; in this embodiment, n=1. In other embodiments, the value of n can be set according to the detection requirements.

[0186] In step S170, the handling control module 811 controls the handling device 20 to transport the bar to the corresponding NG product return station 41, and then the NG product return control module 813 controls the NG product return device 40 to transport the bar from the NG product return station 41 to the NG product return waiting station 42.

[0187] In step S180, the NG product handling control module 814 controls the NG product handling device 50 to transport the bars located in the NG product return waiting station 42 to the re-inspection waiting hopper 51 of the NG product handling device 50; and controls the NG product handling device 50 to transport the re-inspection waiting hopper to the station of the loading device 10; then, return to step S100.

[0188] In step S190, the NG item handling control module 814 transports the bars identified as NG items to the NG item collection box 43 with corresponding size / appearance defects; then, the process ends.

[0189] As described above, the bar inspection and packaging equipment 1 uses the inspection device 30 to perform a first round of inspection on the size and appearance defects of the bar to be inspected to determine whether the bar meets the preset values. The NG product return device 40 transports the bar that does not meet the preset values ​​to the NG product return waiting station 42 for a second re-inspection based on the inspection results. The NG product handling device 50 transports the bar to be re-inspected to the station of the feeding device 10 again to feed the bar to the inspection device 30 for a second round of size and appearance defect inspection. Based on the results of the second round of inspection, it is finally determined whether the bar is an NG product. The bar that is determined to be an NG product is transported to the NG product collection box 43 set in the NG product return station 41 with the corresponding size / appearance defect setting, thereby realizing the classification and storage of NG product bars. Meanwhile, the material handling device 60 picks up the qualified bar stock located at the end station 22 and places it on the material tray 61 for sorting. The automatic boxing device 70 can sequentially transport a row of qualified bar stock that has been sorted to the material box 71 for storage, thereby realizing the automatic sorting and boxing of qualified bar stock.

[0190] Please see Figure 14 ,for Figure 13 The diagram shows a flowchart illustrating the method of "the detection control module 812 controlling the detection device 30 to perform size and appearance defect detection on the bar located in the detection station, and judging whether the bar meets the preset value based on the detection results".

[0191] The detection device 30 includes: a length detection module 32, an end face defect detection module 33, a diameter detection module 34, a chamfer size detection module 35, a rod body defect detection module 36, and a chamfer defect detection module 37.

[0194] In step S120, the detection control module 812 controls the detection device 30 to perform dimensional and appearance defect detection on the bar located at the detection station, and determines whether the bar meets the preset value based on the detection results. Specifically, this includes the following steps:

[0195] In step S200, the detection control module 812 controls the length detection module 32 to perform length dimension detection on the bar located in the length detection station 311, and determines whether the bar meets the preset value based on the detection result; if yes, proceed to step S201; otherwise, proceed to step S170.

[0196] In step S201, the handling control module 811 controls the handling device 20 to transport the bar to the end face defect detection station 312.

[0197] In step S202, the detection control module 812 controls the end face defect detection module 33 to perform end face defect detection on the bar located in the end face defect detection station 312, and determines whether the bar meets the preset value based on the detection result; if yes, proceed to step S203; otherwise, proceed to step S170.

[0199] In step S204, the detection control module 812 controls the diameter detection module 34 to detect the diameter of the bar located in the diameter detection station 313, and determines whether the bar meets the preset value based on the detection result; if yes, proceed to step S205; otherwise, proceed to step S170.

[0200] In step S205, the handling control module 811 controls the handling device 20 to transport the bar to the chamfering dimension detection station 314.

[0201] In step S206, the detection control module 812 controls the chamfer dimension detection module 35 to perform chamfer dimension detection on the bar located in the chamfer dimension detection station 314, and determines whether the bar meets the preset value based on the detection result; if yes, proceed to step S207; otherwise, proceed to step S170.

[0202] In step S207, the handling control module 811 controls the handling device 20 to transport the bar to the bar defect detection station 315.

[0206] As described above, the conveying device 20 and the detection device 30 work together to complete the first round of size and appearance defect detection of the bar stock. Combined with the function of the NG product return device 40, the defective bar stock is returned, so that the detection device 30 can re-inspect the size and appearance defects of the bar stock. The bar stock without defects (i.e., qualified products) is directly conveyed to the end station 22 of the conveying device 20 to wait for sorting and boxing.

[0207] The NG (Not Good) product collection box 43 includes: a length defect NG product collection box 431, an end face defect NG product collection box 432, a diameter defect NG product collection box 433, a chamfer size defect NG product collection box 434, a rod body defect NG product collection box 435, and a chamfer defect NG product collection box 436; corresponding to the length defect NG product return station 411, the end face defect NG product return station 412, the diameter defect NG product return station 413, the chamfer size defect NG product return station 414, the rod body defect NG product return station 415, and the chamfer defect NG product return station 416, respectively.

[0208] Step S190, the NG item handling control module 814 transports the bars identified as NG items to the NG item collection box 43 with corresponding size / appearance defects, specifically including:

[0209] When the length detection module 32 detects that the length of the bar does not meet the preset value, the NG product return control module 813 controls the NG product return device 40 to transport the bar to the length defect NG product collection box 431 set in the length defect NG product return station 411.

[0210] When the end face defect detection module 33 detects that the end face of the bar does not meet the preset value, the NG product return control module 813 controls the NG product return device 40 to transport the bar to the end face defect NG product collection box 432 set in the end face defect NG product return station 412.

[0211] When the diameter detection module 34 detects that the diameter of the bar does not meet the preset value, the NG product return control module 813 controls the NG product return device 40 to transport the bar to the diameter defect NG product collection box 433 set in the diameter defect NG product return station 413;

[0212] When the chamfer size detection module 35 detects that the chamfer size of the bar does not meet the preset value, the NG product return control module 813 controls the NG product return device 40 to transport the bar to the chamfer size defect NG product collection box 434 set in the chamfer size defect NG product return station 414;

[0213] When the rod body defect detection module 36 detects that the surface of the rod body does not meet the preset value, the NG product return control module 813 controls the NG product return device 40 to transport the rod body to the rod body defect NG product collection box 435 set in the rod body defect NG product return station 415.

[0214] When the chamfer defect detection module 37 detects that the chamfer of the bar does not meet the preset value, the NG product return control module 813 controls the NG product return device 40 to transport the bar to the chamfer defect NG product collection box 436 set in the chamfer defect NG product return station 416.

[0215] As described above, the conveying device 20, the detection device 30, and the NG (Not Good) return device 40 work together to complete the second round of dimensional and appearance defect detection of the bars. Bars without defects (i.e., qualified products) are directly conveyed to the end station 22 of the conveying device 20 to await sorting and boxing. Bars still with defects are classified as NG (Not Good). Simultaneously, the NG return device 40 conveys the NG bars to the corresponding defect collection box, achieving classified storage of bar defects. Bars initially found to have defects are conveyed to the feeding device 10 via the NG return device 40 for re-inspection by the detection device 30. Based on the inspection results, the final NG bars are determined, thus avoiding increased NG rates due to detection errors.

[0216] The beneficial effects of the embodiments of the present invention are as follows: Unlike existing technologies, the technical solution disclosed in the embodiments of the present invention uses a detection device to perform a first round of detection on the size and appearance defects of the bar material to be tested to determine whether the bar material meets preset values. The NG (Not Good) product return device, based on the detection results, transports the bar material that does not meet the preset values ​​to the NG product return waiting station for a second re-inspection. The NG product handling device then transports the bar material to be re-inspected to the station of the feeding device to re-feed the bar material to the detection device for a second round of size and appearance defect detection. Based on the results of the second round of detection, it is finally determined whether the bar material is NG (Not Good). The NG bar material is then transported to the NG product collection box set at the NG product handling station corresponding to the size / appearance defect setting, thereby achieving the classified storage of NG bar material. Simultaneously, the sorting device picks up the qualified bar material located at the end station and places it on a sorting tray. The automatic boxing device can transport the sorted row of qualified bar material to the storage box, thereby achieving the automatic sorting and boxing of qualified bar material.
